Abstract

PURPOSE:To purify and also clean the liquid inside liquid tanks quickly and simply with the liquid stored inside the tanks for various kinds of liquids by installing a backflow check valve for dust between a suction hole and a filter case or between the suction hole and a dust reservoir. CONSTITUTION:A backflow check valve 8 is installed between a suction hole 2 and a filter case 1 or between the suction hole 2 and a dust storage 1a. As a result, by putting the suction hole 2 into a liquid tank and starting a pump 7 in a pump chamber 3, the liquid in the tank (a) is purified by a filter 4 in the filter case 1 and discharged out into the tank (a) from a discharge port 5. By moving gradually the position of the suction hole 2 in the tank (a) and operating, dust and sediments in the tank (a) are collected by the filter 4 to clean inside the tank (a) and also purify the liquid inside.

Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention can clean the inside of a fish tank, pool, plating tank, or other tank containing a liquid while the liquid is still inside, and at the same time The present invention relates to a purification device for purifying liquid in a tank.

"Prior Art" Conventionally, there was no purifying device that also cleaned the inside of the liquid tank as described above, which was very inconvenient.

``Problems that the invention aims to solve'' For example, in a plating tank, there may be cases where objects to be plated or other precipitates that escaped from the plating basket into the tank during the plating process accumulate in the plating tank, or If the solution becomes dirty, the inside of the plating solution tank must be cleaned.

In such cases, conventionally, the plating solution was first transferred from the plating solution tank to another tank, and the plating solution was purified by filtration, and the plating material and other sediments that escaped from the plating basket and accumulated at the bottom of the plating tank were removed. It is necessary to take out the items, wash the inside of the tank with water, and return the purified plating solution to the tank.
This cleaning and purification of the solution is extremely time consuming, and the plating apparatus must be stopped during this time, and the quality of the plating solution may change when the plating solution is replaced for cleaning.

Furthermore, cleaning a fish tank is the same; you must move the fish inside to another tank, drain the water in the tank, clean the inside of the tank, and then fill the tank with water adjusted to the water quality suitable for the fish. Therefore, it is very time consuming and wasteful.

An object of the present invention is to be able to purify the internal liquid of a plating liquid tank, a fish culture tank, a swimming pool, and other various liquid tanks while still containing the liquid, and to purify the internal liquid. The object of the present invention is to provide a device that can be easily and quickly carried out.

``Means for Solving Problems'' A first invention provides a suction port, a filter case having a filter therein, a pump chamber having a pump, and a discharge port. A valve for preventing the backflow of dust is provided between the suction port and the filter case so that the air is communicated with the discharge port through a filter in the case.

The second invention is a suction port, a garbage chamber, a filter case having a filter therein, a pump chamber having a pump, and a discharge port. A valve for preventing backflow of dust is provided between the suction port and the dust collection chamber so that the dust is discharged from the discharge port in sequence.

"Operation" When the suction port is inserted into the liquid tank and the pump is started, the liquid in the tank is purified by the filter and discharged from the discharge port into the tank. When operated, the filter traps dust and sediment in the tank, cleaning the tank and purifying the liquid inside. Alternatively, by connecting an appropriate hose to the outlet, the purified liquid in the tank can be temporarily transferred to another container while cleaning the tank.

"Example" FIGS. 1 to 5 show an example of a purification device according to the first invention.

The liquid sucked in from the suction port 2 is purified by being filtered by a filter 4, and is returned to the liquid tank a from the discharge port 5. While the liquid in the can liquid tank a is being circulated in this way, the precipitates and floating dust in the liquid tank a are captured and removed by the filter 4, and
The fluid inside is purified as a whole. A dust backflow prevention valve 8 is provided between the suction port 2 and the filter case 1, so even if the pump 7 is stopped during use, the dust and other trapped objects in the filter case 1 will not flow back into the liquid tank a. do not.

A hose of an appropriate length may be attached to the outlet 5, or a hose may be attached to the outlet 5, and the purified liquid discharged from the outlet 5 can be received in another container and poured into a liquid tank. You may clean the inside of the liquid tank a.
If the tank is a fish culture tank or the like, and the inner bottom of tank a is covered with gravel, etc., a net 22 or a perforated plate is placed over the suction port 2 as shown in Fig. It may be used by configuring the port 2 or a porous suction port, or if there is deposits such as limescale on the inner wall of the liquid tank a, it may be used by arranging the suction port 2 around the suction port 2 toward the tip as shown in Fig. 4. Facing brush 23
It is preferable to attach the suction port 2 with a brush and use the brush 23 to scrub the inner wall.

FIG. 6 and FIG. 7 show an embodiment of the purifying device according to the second invention.

A dust collection chamber 1a is provided below the filter case l, and the filter case l and the dust collection chamber la have a transparent integral outer cylinder 13, and the upper end of the outer cylinder 13 is connected to the upper pump chamber 3. A screw cap 14 formed in the shape of a flange is screwed together, and a screw cap 15 having a socket portion 11 for connecting the communication pipe 21 in the center portion is screwed to the lower end of the outer cylinder.

An air bleed valve 18 is provided on the screw cap 14 at the upper end of the outer cylinder 13.1 When the filter case l is inserted into the liquid in the tank from the suction port (not shown), the liquid in the tank reaches the pump chamber 3. It is desirable that the filter case 1 and the dust collection chamber 1a are communicated with each other through a screen or a perforated plate 18 with holes 17, so that the filter case 1 and the dust collection chamber 1a are communicated with each other through a screen or a perforated plate 18 with holes 17 formed therein so that large dust can be easily started by the filter. It is desirable to avoid entering the case l.

An end 24 of a communication pipe 21, the other end of which is connected to a suction port (not shown), is inserted into the socket 11 of the screw cap 15 at the lower end of the outer cylinder 13 in such a manner that it projects into the waste collection chamber la. The distal end surface of the end portion 24 forms a valve seat of a check valve 8 provided between the suction port at the other end of the communication pipe 21 and the waste storage chamber 1a.

A cylindrical filter 4 provided in an edge shape inside the filter case 1 is attached to the outer periphery of an inner cylinder 41 having a plurality of holes 42 communicating with the pump chamber 3, and the upper end of the inner cylinder 41 is connected to a first Similar to the embodiment of the invention, the sleeve-like communication port 32 integrated with the pump chamber 3 is screwed together to connect the pump chamber 3.
In addition, a pipe bolt-shaped screw cap 44 that also serves as a guide cylinder for the check valve 8 is screwed into the lower end of the inner cylinder 41, and this screw cap 44 also supports the perforated plate 18. ing.
