Abstract

A filter plate for filtration is used for high-pressure filtration. The method is mainly used for sludge dehydration treatment. There are two ways to increase the sludge dewatering rate, one is to lengthen the time for filtering the sludge to be filter-pressed, and the other is to apply a greater pressure to the sludge to be filter-pressed. Exert big pressure and need the filter screen to have sufficient intensity, the utility model discloses a constitute by the stack of many fluted plates, form many apertures, play the filtering action. The pressure resistance in the direction of the small hole is improved because the small hole can be lengthened. The filter plate of the utility model has simple structure, easy processing and constitution. The intersecting grooves formed in the groove plate can reduce or slow the occurrence of the phenomenon that the formed small holes are blocked.

Description

Filter plate for filtering

Technical Field

The invention belongs to the technical field of filtering equipment, and particularly relates to a filter plate for filtering.

Background

Filtration is often used in daily life and in factory production. For example, when bean curd is made in a house or a processing factory, the bean curd coagulated into blocks is wrapped by a filter cloth, and then some water is extruded under a proper pressure to make the bean curd into blocks which are convenient to eat. The filter cloth plays the role of a filter screen. In the aspect of environmental protection, the treatment of sludge is one of the means of squeezing out the moisture in the sludge through a filter screen. The sludge generated by mine ore washing needs to be squeezed out by adopting a filtering mode. The problem is that a certain pressure is required to squeeze out the water content in the sludge and the sludge generated by washing the ore. The pressure is high, the strength of the filter screen cannot bear, and the water content in the sludge is high due to low pressure. The effect on sludge treatment is not ideal.

Patent No. 201720638775.0 discloses a filter screen plate, which is made by extruding or cutting a high-strength plate through a die to form a plurality of grooves. The plates are then stacked to form a thicker plate, and the grooves, when aligned in the plane of the plates, define a plurality of apertures. The plates are used to form a filter plate to allow moisture in the sludge to pass through the pores to remove the dried sludge. The advantage of this filter screen plate is that its strength can be made very high, and in practical application, it can use different materials or the method of forming the thickness of the filter plate to meet the requirements of application.

Disclosure of Invention

The invention aims to provide a filter plate for filtering, which is also provided with grooves. Wherein the length of the groove extends from the plane of the plate to two end faces of the plate thickness, and emphasizes that the plate is provided with other grooves which are intersected with the groove, and the intersection part enables the grooves in different directions to be mutually communicated. The advantage of providing intersecting channels is that when a channel plate is superimposed on a planar plate, a plurality of apertures are formed. When some portion of the middle of the pores is blocked, the pores can no longer function as filters. If a plurality of crossed grooves are formed in the grooves, when a small hole is partially blocked, water can transversely flow through the crossed grooves and can be discharged through other communicated holes. Although the filter plates can be disassembled and reassembled into the filter plates after cleaning, compared with the filter plate of patent No. 201720638775.0, the filter plates with the crossed grooves can reduce or slow down the advantage of reducing the filtering effect caused by partial blockage.

The invention has simple structure, easy structure and simple processing method. It is thought that if it is desired to increase the strength of the filter screen, it is quite difficult to form many small holes in a thick steel plate.

The small holes can be lengthened, so that the formed filter plate has improved pressure resistance in the length direction of the small holes.

Technical scheme

A filter plate for filtration, comprising: end plates and fluted plates. The method is characterized in that:

a large end face of the grooved plate is provided with a plurality of first grooves in the same direction, and the grooves extend to the plane of the plate to end faces with two thicknesses. A plurality of second grooves in the same direction are formed in the same large end face of the groove plate and are communicated with the first grooves in a crossed mode. The shapes of the cross sections of the first groove and the second groove are not limited, so that liquid can conveniently flow. The cross-sections of the first and second trenches may be equal or unequal, but the advantage of the larger cross-section of the second trench responsible for the lateral conduction than the first trench is that the second trench is shunting-free and does not filter, so the cross-section of the second trench is large for shunting and is not easy to block.

One large end face of the end plate abuts the grooved face of the fluted plate. The grooved surfaces of the plurality of grooved plates abut the flat surfaces of the adjacent grooved plates on the sides where no grooves are formed.

As shown in fig. 1 and 2, the above description constitutes the basic function of the filter plate, and the end plates and the fluted plate constitute a plurality of small holes having a diameter smaller than the outer diameter of most particles of sludge. When one side of the filter plate contains sludge with moisture, the moisture in the sludge is removed through the holes under the action of pressure. Due to the difference in size, shape and physical properties of the sludge particles, elastic particles, plastic particles and particles with smaller size may enter the formed pores, i.e. the pores formed by the first grooves, causing the channels of some pores to be blocked. The second grooves are arranged in the same direction and are communicated with the first grooves in a crossed mode. The aim is to reduce and alleviate the occurrence of the blocking phenomenon. If a partial blockage occurs in one of the small holes, water in the hole is removed through the hole formed by one of the second grooves which intersect with the hole formed by one of the first grooves which is not blocked. The filter function of the filter plate is prevented from being lowered after the filter plate is partially clogged due to the excessive pores. The second groove is communicated with the first groove in a crossed mode, the crossed angle of the second groove is preferably 90 degrees, and therefore the filtered liquid cannot flow reversely to affect the filtering of a normal filtering channel.

The cross section of the second groove is larger than that of the first groove.

The purpose of this is to prevent the particles entering the filter holes from blocking in the holes formed by the second grooves to the greatest extent and to avoid the hole shunting effect formed by the second grooves from failing.

The cross section of one side of the first grooves is larger than that of the other side of the grooves, and the first grooves are tapered.

The purpose of the part is that when the water in the sludge is squeezed out, the water containing smaller particles is discharged together with the water entering the holes formed by the first grooves, if the small holes formed by the first grooves are conical, the smaller particles in the discharged water enter through the small hole side, and the cross section of the passing channel is larger and larger, so that the smaller particles in the water can be discharged.

The other large end face of the groove plate is provided with a plurality of identical first grooves and a plurality of second grooves which are mutually crossed and communicated with the first grooves. Wherein, the large cross sections of the first grooves on the two large end surfaces of the groove plate are arranged on the same side.

As shown in fig. 3, the same first grooves and second grooves are formed on both large surfaces of the groove plate, so that the number of filter holes constituting the filter plate is increased, in the case of a filter plate constituted by the same number of end plates and groove plates.

One large end face of the end plate abuts a large face of the fluted plate. The large faces of the plurality of groove plates abut against each other, and the large end face of the end plate similar to the end plate abuts against the outer side of the groove plate at the end. When the grooves are arranged on the two surfaces of the groove plate, the filter plate is provided with two end plates.

As shown in fig. 4, the purpose of this part is to realize a filter plate with more filter holes, and to emphasize that the formed tapered holes, small-end holes are all arranged on the same side of the filter plate, which is more beneficial to filtering.

Detailed Description

Example 1

A filter plate for filtration, comprising: an end plate 1 and a fluted plate 2. The method is characterized in that:

a large end face of the fluted plate 2 is provided with a plurality of first flutes 3 in the same direction, which extend to the plane of the plate to end faces of two thicknesses. A plurality of second grooves 4 in the same direction are arranged on the same large end face of the groove plate 2, and the grooves are communicated with the first grooves 3 in a crossed mode.

One large end face of the end plate 1 abuts the grooved face of the fluted plate 2. The grooved surfaces of the plurality of fluted plates 2 abut the flat surfaces of the adjacent fluted plates 2 on the sides where no grooves are formed.

As shown in fig. 1 and 2, the filter plate is configured such that water squeezed out of sludge is removed through the holes formed by the first grooves 3. If a partial blockage of a bore formed by the first channels 3 occurs, the drained water is transferred via the bore formed by the second channels 4 intersecting it to the other non-blocked bore formed by the first channels 3.

Compared with the filter sieve plate of patent No. 201720638775.0, the filter sieve plate of the invention has the greatest advantage that when some filter holes are partially blocked, the crossed channels are formed to excessively divide the liquid entering the filter plate to other non-blocked holes for removal. Therefore, the filter plate can reduce the deterioration of the filtering effect when a certain filtering hole is partially blocked, and prolong the single service life of the filter plate.

Example 2

Example 2 of a filter sheet for filtration is substantially the same as example 1, except that:

the cross section of the second groove 4 is larger than that of the first groove 3.

The impurities mixed into the formed small holes are not blocked in the hole channels formed by the second grooves 4 so as not to affect the flow dividing function of the hole channels formed by the second grooves 4.

Example 3

Embodiment 3 of a filter sheet for filtration is substantially the same as embodiment 2 except that:

the cross section of one side of the plurality of first grooves 3 is larger than that of the other side, and the first grooves 3 are tapered. I.e. the filter channel formed is flared.

When the mixed smaller particulate matters are injected into the filter plate through the small hole side along with the liquid to be discharged, the smaller particulate matters are not dissolved and blocked when passing through the discharge hole channel.

Example 4

Example 4 of a filter plate for filtration is substantially the same as example 3, except that:

the other large end face of the groove plate 2 is provided with a plurality of identical first grooves 3 and a plurality of second grooves 4 which are mutually crossed and communicated with the first grooves 3. Wherein, the large cross sections of the first grooves 3 on the two large end surfaces of the groove plate 2 are arranged on the same side.

The same first groove 3 and second groove 4 are opened on both sides of the groove plate 2, increasing the number of small holes formed by the groove plate 2.

Example 5

Example 5 of a filter plate for filtration is substantially the same as example 4, except that:

one large end face of the end plate 1 abuts against a large face of the fluted plate 2. The large surfaces of the plurality of groove plates 2 abut on each other, and the large end surface of the other end plate 1 similar to the end plate 1 abuts on the outer side of the groove plate 2 at the end.

The filter plate consisting of the groove plates 2 with the first grooves 3 and the second grooves 4 on both sides should have two end plates 1.

In order to realize the result that when a certain filter hole is partially blocked, the opened crossed channel excessively divides the liquid entering the filter plate to other non-blocked holes for removal, the technical scheme is obtained through repeated tests.
