Description

A filter press system equipped with vibration or rotation device of filter cloth

The present invention relates to a filter press system, and in particular, a filter press equipped with a filter cloth vibration or rotating device, which enables automatic vibration and simultaneous rotation of a plurality of filter cloths, thereby enabling automatic detachment and automatic cleaning of a cake attached to the filter cloth. It's about the system.

In general, wastewater treatment processes that purify or recover toxic substances or hazardous substances from wastewater generated by industrial processing of cement, aggregate, food, chemical, steel, aquatic products, pharmaceuticals, or paints are treated to a predetermined acceptable water quality. This is essential.

Wastewater treatment processes to remove toxic or harmful substances include physical treatment or microbiological treatment. Suspensions, slurries, etc. are generated during the treatment. However, these suspended solids, slurries, and the like contain moisture and are bulky and heavy. Therefore, dehydration is included to remove moisture contained in suspended solids, slurries, and the like in the wastewater treatment process.

One device used in the dehydration process is a filter press system. A filter press is an industrial pressure filtration apparatus for separating and filtering solids contained in a liquid into a liquid and a solid, respectively. The filter press is a device for applying a pressure to a filter plate equipped with a filter cloth to perform a dehydration process. Specifically, the filter press pressurizes the slurry, which is a liquid dehydration object in a liquid state, to a filtration chamber by pressurizing it with a pump or the like, and the slurry supplied to the filtration chamber is dehydrated by squeezing by using a plurality of filter plates. The slurry, which was in the state, is separated into a filtrate (dehydration solution) and a cake.

Next, the cake is separated downward by its own weight in the process of releasing the pressing and spaced apart the filter plates compressed with each other at predetermined intervals. As such, the slurry flows through the filter cloth attached to the filter plate, and the inevitable problem of cakes inevitably occurring during the filtration process is not attached to the filter cloth, etc., and the filtration efficiency decreases due to clogging of the filter cloth. Although not guaranteed, the desorption of cakes and contaminants that have not been removed from the filter cloth is a problem that is mostly performed by hand.

In the prior art "Patent Press Separation Device for Filter Press" of Patent Document 1, a filter cloth vibrating means for repeatedly expanding and relaxing the filter cloth bonded to the outside is used to separate the residual cake. However, in order to repeatedly drive the filter cloth to the left and right sides, a filter cloth vibration means composed of a cylinder inserted in both sides of the filter plate and a pair of pistons slidably in the transverse direction via a spring in the cylinder is separately required. There is a problem.

In consideration of the sizes of the hook portion 100, the gears and the shafts, the positions of the components may be variously configured in relation to the hook portion 100.

Further, according to the second aspect for the simultaneous roll rotation of the plurality of filter cloth 60 of the present invention, as shown in Figures 6 to 8,

Filter cloth 60 is mounted on the front and rear of each filter plate 50, it is mounted in the form of a circulation ring while wrapping the front and rear of the filter plate 50 up and down, respectively supported horizontally from the upper and lower sides by the filter cloth support rod (70) It can be configured in such a way.

The filter cloth 60 is supported by the upper and lower sides of the pair of filter cloth support rods 70 that are horizontally movable and rotatable on each of the upper frame (not shown) and the lower frame (not shown), respectively, the filter plate 50 It is disposed between and can be mounted in the form of a circulation ring while wrapping up and down the front and rear surfaces of each filter plate 50.

On the other hand, one of the pair of filter cloth support rods 70 for supporting the upper side and the lower side of the filter cloth 60 is provided with the following support gear 190 as the drive side, the other is provided with a roller (not shown) to the driven side Can be.

In addition to the main frame 10, the upper frame and the lower frame formed with a horizontal guide groove (not shown) to support the upper and lower filter cloth support rod 70, and a vertical frame (not shown) to vertically connect and support these frames Of course) may be further provided.

The inner side of the hook portion 100 is provided with a timing gear 180 that is coaxially connected to the main gear 110, not the configuration associated with the eccentric cam 130 of the first aspect, and is provided with the timing gear 180. A timing belt 185 and a support gear 190 to be connected may be provided outside the hook portion 100.

In consideration of the sizes of the hook part 100, the timing gears and the timing belts, the positions of the components may be variously configured in relation to the hook part 100.

The timing gear 180 is configured to adjust the rotation timing of the filter cloth 60 according to the rotation of the main gear 110, the support gear 190 is provided at the end of the at least one filter cloth support rod 70, thereby timing The belt 185 is wound around the timing gear 180 to support the roll rotation of the filter cloth 60 when the main gear 110 rotates.

Therefore, when the rotation driving force is transmitted to the main gear 110 by the one-way rotation of the ratchet gear 120 as described above, the support gear 190 is rotated by the timing gear 180 and the timing belt 185. , The filter cloth 60 is rotated up and down while the filter cloth 60 around the filter plate 50 with the upper and lower filter cloth support rods 70 as the axis to remove the cake or contaminants not detached.

The first and second aspects of the present invention are configured such that the rotational driving force is transmitted to the main gear 110 only by one direction rotation of the ratchet gear 120 by the configuration of the ratchet gear 120 and the main gear 110. Is the same.

That is, when the filter plate 50 is moved in the direction in which the filter plate 50 is pressed by the pressing plate 30, the ratchet gear 120 is idling while the rack chain 200 is not driven. No driving force acts on), but in the process of sequentially separating the filter plates 50 by the filter plate moving unit 40 to restore the original state after the compression and filtration, the rack chain ( The ratchet gear 120 is rotated by being engaged with the 200 to transmit the rotational driving force in one direction to the main gear 110 by the ratchet key 122 to rotate the main gear 110.

Accordingly, the filter cloth 60 is vibrated up and down by the eccentric cam 130 and the cam shaft 140 and / or the vertical shaft 160 connected to the main gear 110, or the timing gear connected to the main gear 110. The filter cloth 60 is roll-rotated by the 180 and the support gear 190.

In addition, the filter plate 50 is separated from the filter plate 50 in the original state by the filter plate moving part 40 as well as the process of transferring the filter plate 50 to the state before being compressed (see FIGS. 3 and 6 (b)). By driving the rack chain 200 at a predetermined speed by a separate rack chain driving means (not shown) in the state, the main gear 110 by simultaneously rotating the respective ratchet gears 120 engaged with the rack chain 200 By transmitting the rotational driving force to the filter cloth 60 can be vibrated or rotated at the same time.

During the process of transferring the filter plate 50 to the state before being compressed, since the stroke distances from which the compressed filter plates 50 are pressed to their original positions before compression are different for each filter plate 50, the filter cloth 60 according to each stroke distance The amount of oscillation or rotation is also different so that the same detachment / cleaning effect is not obtained for each filter cloth 60. To compensate for this, the filter cloth 60 is vibrated at the same time in a state in which the filter plate 50 is completely spaced apart. Or to rotate it.

In addition, the roll rotation direction of the filter cloth 60 can be changed according to the direction which drives the rack chain 200. FIG. That is, FIG. 8 illustrates a case in which the rack chain 200 is driven in a direction opposite to the direction in which the filter plate 50 moves to the state before the filter plate 50 is pressed. In the process of moving the filter plate 50, the filter cloth 60 is roll-rotated. And roll the filter cloth 60 in the same direction at the same time. However, when the rack chain 200 is driven in a direction moving to the state before the filter plate 50 is pressed, the filter cloth 60 is rotated in the opposite direction as the filter cloth 60 is rolled in the process of moving the filter plate 50. Rolls are rotated simultaneously.

Thus, contaminants not detached from the filter cloth 60 can be effectively removed.

In addition, in the process of transferring the filter plate 50 to the original state before being compressed, it is possible to cause the filter cloth 60 to occur only in a state in which all of the original state is not vibrated or rotated.

That is, when the filter plate 50 is moved in the pressing direction by the pressing plate 30, and in the process of sequentially transferring the filter plate 50 to the state before being pressed, the ratchet gear 120 is connected to the rack chain 200. The driving force of the filter plate 50 is not transmitted to the main gear 110 by being separated without being engaged, and the ratchet gear 120 is rack-chained when the separation of the filter plate 50 is completed as it is. After it is engaged with the 200 (for example, by moving the rack chain 200 provided in the main frame 10 by a separate drive means upwards in the direction of the ratchet gear 120) the rack chain by means of the rack chain drive means By driving the 200 in one direction, the ratchet gear 120 may rotate the plurality of ratchet gears 120 simultaneously in a direction in which the driving force may be transmitted to the main gear 110.

Although the speed at which the filter cloth 60 vibrates or rotates in the process of transferring the filter plate 50 to the state before being compressed is determined according to the driving speed of the filter plate moving part 40, the rack chain 200 is driven by the rack chain driving means. In the case of driving the rotation amount of the ratchet gear 120 is changed according to the driving speed of the rack chain 200, it is possible to vary the amount of vibration or rotation of the filter cloth 60 according to various operating conditions.

On the other hand, on the upper side of the main frame 10, for example, the water spraying the water while having a predetermined inclination with respect to the filter plate 50 at a position that can cover the range of stroke distance that the compressed filter plate 50 moves to its original position Injector 300 is included. At this time, the water can be sprayed only while the filter plate 50 is moved to the original position, or at the same time in the process of vibrating or rotating the filter cloth 60 in the state in which the filter plate 50 is moved away from the original position It can be sprayed with water.

The water injector 300 may be fixed at a predetermined position of the main frame 10 as shown in the illustrated ratio, or may spray water while moving along with the movement of the filter plate 50 along the main frame 10.

Although the present invention has been shown and described with reference to the preferred embodiments as described above, it is not limited to the above embodiments and those skilled in the art without departing from the spirit of the present invention. Various changes and modifications will be possible.
