Description

Water-saving water-saving device for reverse return method of construction machinery construction

The present invention relates to a water-saving water supply system for the reverse return method of construction machinery and equipment construction, and more particularly, in the case of central heating or district heating in an apartment house (apartment), etc. It relates to a water-saving water supply system for the reverse return method of the construction machinery facility construction improved so that it can be used.

In general, it is used in apartment complexes, etc. Currently, hot water supply (hot water) is a system that manages a certain area collectively, and a large amount of water is heated at once and supplied to the household (hereinafter referred to as the place of use).

As described above, the supplied hot water is continuously circulated within a certain range, but only the main main pipe is circulated. The hot water can be used only after the water contained in the pipe is discharged for a certain period of time after opening the faucet.

This problem occurs when the currently used system uses hot water at the place of use, especially in the morning, when re-using hot water after a certain period of time has elapsed. do.

Therefore, it can be seen that the amount of cooled water discharged and discharged while waiting for hot water at a desired temperature by the user at the place of use corresponds to the user residing in the apartment complex.

This is because the pipe branching into the place of use forms a considerable length through the hot water meter to the place of use, so not only heat loss occurs due to water in the supply pipe that is not circulated, but also the phenomenon of temperature drop in the pipe to the place of use is common in apartment houses, etc. It is even worse in the place where the square of the place of use is large.

Looking back at the conventional return system as described above, as shown in FIG. 1 , the water supplied from the storage tank through the heater 8 is supplied through the rising main pipe 4, and the rising main After being transferred to the transverse pipe 6 through the hot water pipe, the hot water circulated through the round hot water pipe and the hot water supply pipe directly supplied to the home are formed.

The hot water circulated to the round hot water pipe is circulated to the storage tank where it was initially sent through the round hot water pipe 12 so that the heated hot water is circulated so as not to cool it.

A hot water meter (not shown) is installed at the beginning of the conventional hot water supply pipe configured as described above to check the amount of hot water supplied and hot water supplied.

Therefore, the hot water supplied and circulated from the storage tank through the heater 8 is not introduced to the place of use, but is circulated only to the hot water meter installed at the inlet of the hot water supply pipe.

When hot water is used at the place of use by the return method as described above, the amount of water that cools down as much as the length of the pipe installed inside the place of use is quite large, and the problem of measuring the hot water bill that has never been used arises.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as being limited to the embodiments described herein.

2 to 5, the present invention is jointly managed with the central heating method or district heating method used in apartment complexes among the methods adopted to save water resources and energy, and in particular, ), a large storage tank/heater 8 is formed to heat and supply water to supply hot water to the place of use (household).

In order to supply hot water to the place of use in the apartment complex, etc., the heated water is transferred from the storage tank through the heater 8 through the standing main pipe (4).

The hot water transferred through the standing main pipe (4) is transferred to the horizontal main pipe (6) in order to transfer the hot water to the hot water supply pipe (16) for supplying it to the place of use in the complex made by each group.

Since the reverse return method is provided with piping at a distance from the complex and the place of use, it is classified into a standing main pipe (4) and a horizontal main pipe (6) as shown.

An automatic air discharge valve (2) is formed between the rising main pipe (4) and the transverse main pipe (6), which are piped as described above, for discharging air bubbles generated in hot water or air bubbles entering from the outside. to remove

The transverse pipe 6 is transferred to the hot water supply pipe 16 made up of each group, and the hot water transferred to the hot water supply pipe 16 is transferred to the place of use and circulated to the faucet of the place of use.

The hot water circulated up to the faucet 20 of the present invention is piped so that if it is not discharged through the outlet of the faucet 20, it is continuously circulated and discharged through the circulating water pipe 11.

Unused hot water circulated to the round-hot water pipe 11 is transferred back to the storage tank via the round-hot water pipe 12, then mixed with the previously stored hot water and heated, and then circulated in the same manner as above.

According to the present invention configured as described above, when the user opens the faucet 20 as shown in FIGS. 2 and 3 in order to use hot water at the place of use, the switch is installed on the faucet 20 as shown in FIG. 5 . When the state of the faucet 20 detects a change in the position of the faucet 20 to discharge hot water, the current automatically flows and operates the inflow switching valve 30 installed at the hot water inlet side of the place of use.

The inflow selector valve 30 is, until the hot water flowing from the hot water supply pipe 16 to the place of use is used, the inflow selector valve 30 is piped to one place of use in a reverse return method, and to the hot water supply pipe 16 Since it is installed right in front of the installed hot water flow meter 28, a bypass pipe 26 is formed with the hot water flow meter 28 as a boundary, and it circulates to every corner of the place of use, exits the place of use, and passes through the hot water pipe 11 ) is cycled.

However, when the interior of the place of use is generally classified as shown in FIG. 3 , only one faucet 20 among the kitchen faucet 40 , the bathroom 1 faucet 42 , and the bathroom 2 faucet 44 . Since the switch installed in the faucet operates even if it works, the inflow switching valve 30 converts the flow of hot water that immediately flows into the bypass pipe 26 to the pipe in which the hot water flow meter 28 is installed and sends it to the bypass pipe 26 side closed. From this time, the hot water flow meter 28 is operated to check the amount of hot water discharged through the faucet 20 .

Since the supplied hot water is piped to be circulated to the faucet 20 of the place of use, it has a feature of being piped so that the user can immediately obtain hot water of a desired temperature at the same time as the faucet 20 of the present invention is opened.

In order to measure only the quantity of hot water discharged to the faucet 20 of the present invention, in the present invention, a shut-off valve 24 is formed to block the flow of hot water and prevent circulation by blocking the flow of hot water at the end of the hot water pipe exiting through the place of use. When the faucet 20 is operated, it is operated simultaneously with the inflow switching valve 30 to control the quantity of hot water so that the quantity of incoming hot water is discharged only from the faucet 20, so that only the hot water used in the place of use is measured.

In addition, when the faucet 20 is closed at the place of use, contrary to the above operation, the contact point is dropped by a switch means such as a mercury switch that is detected by sensing the inclination, etc. If the state of the inflow switching valve 30 is changed to the bypass pipe 26 side, the operation of the hot water flow meter 28 is stopped.

In addition, the shut-off valve 24, which blocks the circulation of hot water, is also operated at the same time as the inflow switching valve 30 to open the blocked hot water to circulate. The flowing hot water does not cool and maintains an appropriate temperature.

Since hot water of the desired temperature can be obtained from the faucet 20 from the beginning by the device of the present invention as described above, there is no need to wait for the hot water to be discharged over time, and there is no need to wait for the hot water to be discharged over time, as well as a pipe of a certain length as in the conventional method. In order to discharge the cooled water from the faucet, there is a feature that the hot water can be used directly without the amount of water discharged through the faucet.

The water-saving water-saving water supply device for the reverse return method of the construction machinery and equipment construction of the present invention made as described above will be described in more detail while looking at the circuit diagram shown in FIG. 4 .

When any one of the switches of S/W1, S/W2, S/W3, S/W4, and S/W5 attached to the faucet 20 of the present invention is operated, the current flowing to both sides is connected and the relay 60 operates do.

When the relay 60 is operated, the contact R1(:|) shown in the drawing is attached, and as the contact part of R1(|:) falls, the timer 70 stops, and the relay 63 operates. And since the relay attaches the contact part of R2, the actuators 66 and 68 are operated to simultaneously operate the inflow selector valve 30 and the shutoff valve 24.

As described above, the inflow switching valve 30 switches the flow path to the hot water flow meter 28, and the shut-off valve 24 is closed to measure the used hot water.

In addition, it does not matter whether the number of switches installed in each faucet is increased and used, and since only the switch installed in one faucet is operated, there is no particular problem.

In addition, when switching the flow path of hot water flowing into the place of use, if the faucet 20 is closed in the reverse order to the above operation, the contact part of the switch cuts off the current flowing away, and blocks due to the operation of the switch as described above When the relay 60 is cut off operation.

When the operation is as described above, the R1 part (:|), where the relay 63 is installed, is disconnected, and conversely, the R1 part (|:) installed in the timer 70 part has a contact.

Therefore, the timer 70 is activated at the same time, and after a predetermined time has elapsed, the timer relay 62 is operated to cut the circuit.

Therefore, the relay 63 is cut off, and the R2 part and the actuators 66 and 68 are operated to change the flow path of the inflow selector valve 30 to the bypass pipe 26, and the shutoff valve 24 is installed so that it is opened. The hot water continues to circulate.

In particular, the introduction of the timer 70 is characterized by preventing the frequent operation of the inflow switching valve 30 and the shutoff valve 24 when the faucet 20 is opened and closed.

On the other hand, the heater 8 is a kind of boiler equipment, and since it is large-capacity, a stack (STC) is installed to exhaust harmful gases generated when burning LNG or LPG raw materials, and the stack (STC) is usually located on the roof (TOP). installed protrudingly.

The present invention installs a turntable (TAB) rotatably on the rooftop (TOP) next to the stack (STC), and includes a support post (POS) rotatable by 90° by the turntable (TAB).

In this case, the support post (POS) is a fixed structure in the shape of 'a' having a bent end portion (TER) bent vertically.

And, the turntable (TAB) is configured to be rotatable by the rotary motor (MOT) by a known gear combination, for example, a bevel gear combination. However, since this assembly is a structure widely used in the industrial field, a detailed illustration of the structure will be omitted.

In addition, a winch WIN is fixed to the bent end TER, and the winch WIN is a funnel STC when the bent end TER is arranged in the radial direction at the top of the stack STC. It is arranged so that it can be located at the center of the circle.

In addition, the winch (WIN) is a double-axis winch, and a drum (DRM) is fixed at both ends, respectively, a wire (WIR) is wound around the drum (DRM), and the end of the wire (WIR) is the upper part of the purification tank (100) bound at both ends.

Therefore, as the winch (WIN) is operated, the purification tank 100 can be raised and lowered.

Here, the purification tank 100 is a kind of housing in which a plurality of known purification balls are filled, and since it is configured in a mesh shape, harmful substances contained in the atmosphere are finally discharged after purification treatment such as decomposition and absorption.

At this time, the purification ball is based on 100 parts by weight of the polyurethane resin, 10 parts by weight of vinyloxymosilane, 10 parts by weight of ferric chloride (FeCl ₃ ), 3.5 parts by weight of benzoguanamine, 5 parts by weight of a grass concentrate, 5 parts by weight of resorcinol After mixing parts by weight, 10 parts by weight of glutaryl concentrate, and 5 parts by weight of terbium, it is cooled while dropping it in the form of droplets to form a ball. do.

In this case, vinyl oxymosilane (Vinyl Oximeino Silane) is added to increase the binding strength of the transition metal ferric chloride.

In addition, ferric chloride (FeCl ₃ ) is a trivalent iron salt, which is a transition metal having oxidizing power. Since it has a strong oxidizing power in a high temperature environment, it reacts with the high temperature exhaust gas in the stack to increase the decomposition power of harmful components.

In addition, benzoguanamine is added to maintain adhesion stabilization while maintaining electrostatic properties, and grass concentrate is a dark brown dry distillate made when carbonizing wood. Therefore, it is added for this purpose.

In addition, resorcinol is intended to increase the wet and dry strength, and to increase the deodorization power while maintaining the crosslinking strength due to high temperature resistance.

In addition, Glutaral Concentrate absorbs and decomposes harmful components while reacting with heat.

In addition, terbium is a rare earth metal belonging to the lanthanide group, a silvery-white metal with high malleability and ductility, and reacts under high heat to absorb and remove harmful metal components.

On the other hand, the purification tank 100 is formed in a rectangular frame body, as in the example of FIG. 2 , a pair of side frames 110 , and an upper frame 120 assembled and fixed to the upper end of the side frame 110 , and a front frame 130 and a rear frame 140 respectively assembled to the front and rear ends of the side frame 110 and the upper frame 120 .

At this time, the side frame 110 , the upper frame 120 , the front frame 130 and the rear frame 140 have a heat-resistant iron mesh (W) fixed to the rectangular frame (F) so that the exhaust gas flows smoothly. made to go.

In this case, the iron mesh network (W) is configured to have strong rigidity and high heat resistance by being welded and fixed to the frame (F) so that it can sufficiently withstand in the stack (STC).

In addition, the side frame 110 , the upper frame 120 , the front frame 130 and the rear frame 140 are each manufactured as a single unit, and when they reach the stack (STC) to be installed, each frame is assembled and fixed with each other. Because it is installed in this way, the efficiency according to transportation and loading is increased.

In addition, since it is configured to be easily dismantled, there is an advantage of easy maintenance.

That is, by fastening each frame (side frame, upper frame, front frame, rear frame) with the clamp 200 in a state in which they are facing each other, it is possible to assemble and install the purification tank 100 very easily, quickly and strongly.

In order to have such a structure, it is better if the frame (F) is in the form of a square pipe.

And, the clamp 200 is clamped in such a way that the latch 220 provided on the push knob 210 is caught by the fixing member 230 .

To this end, the body of the push knob 210 is fixed to the frame (F) on one side of the frame in contact with each other, and the fixing member 230 is fixed to the frame (F) on the other side.
