Description

Filter plate group structure improvement

The present invention relates to a filter plate, and more particularly to a filter plate assembly structure that is used on a filter press and selectively combined.

The structure of the filter plate set installed in the conventional filter press is improved, and the respective filter plates and filter cloths in the improvement of the filter plate group structure are selectively combined according to the operation of the filter press, thereby performing filtration.

However, after the combination of the filter plates and the filter cloths, the filter plates and the filter cloths are not tight enough, and leakage may occur during the filtration process, thereby reducing the filtration efficiency, and even the filter plates are subjected to excessive pressure, which causes the filter plates to rupture.

Moreover, the mud cake is deposited between the filter plates in the conventional use, and the mud cake pushing may also cause the filter plate to be deformed and damaged, and cannot be used, so the filter plate still needs to be improved.

In view of this, how to eliminate the above-mentioned defects is the technical difficulty point that the inventor of the case wants to solve; however, the inventor of this case is based on years of experience in the relevant industry, after many years of painstaking research, trial improvement, finally Successfully developed the case and made the invention born to enhance the efficacy.

In view of the above disadvantages, the filter plate assembly of the present invention has an improved structure, comprising: at least two filter plates, each of which has a filter cloth on one side of each of the filter plates, each filter plate having a plate frame and a central portion The plate frame has elasticity, and a first liquid discharge pipe is respectively disposed on both end faces of the frame frame; the center portion is recessed in the frame frame, and at least one plate body is embedded in the center portion. The central portion and the plate body are provided with at least one corresponding perforation, and the plate frame and the central portion have a step portion, and the step portion is respectively provided with a plurality of through holes communicating with the first drain pipe Each of the filter plates is combined at the time of filtration so that the perforations are opposed to each other, and a filter chamber communicating with the outside is formed between the central portions of each of the filter plates, each of the perforations providing a slurry flow through the mud to deposit the mud The filter chamber is filtered by each filter cloth, so that the liquid in the mud flows through the first drain pipe through each of the through holes.

The main purpose of the structural improvement of the filter plate set of the present invention is to:

1. By improving the stability and pressure resistance of the center by the plate body, it will not be deformed and damaged by the mud pushing.

2. The adhesion of each filter plate is higher, and a plurality of ribs are arranged on the filter plate, which can more effectively filter and discharge liquid, remove mud cake, and improve the degree of mud biscuits.

In order to facilitate the review of the contents of the present invention and the effects that can be achieved by the reviewing committee, the specific embodiments will be described with reference to the drawings, and the detailed description is as follows: Please refer to the first figure and the second figure, and the structure of the filter plate set of the present invention is improved. The first embodiment includes at least two filter plates 10, wherein each filter plate 10 has a plate frame 11 and a central portion 12, respectively.

The plate frame 11 has elasticity (in this embodiment, it is elastic on the outer side of the plate frame 11), and the first liquid discharge pipes 111 communicating with the outside are respectively disposed on both end faces of the plate frame 11.

The central portion 12 is recessed in the plate frame 11, and at least one plate body 13 is embedded in the center portion. In the embodiment, the plate body 13 is made of metal.

The central portion 12 and the plate body 13 are provided with at least one corresponding through hole 121. The plate frame 11 and the central portion 12 have a step portion 20, and the block portion 20 is respectively provided with a plurality of the first row The liquid pipe 111 communicates with the through hole 21.

The central portions 12 are each polygonal, and each of the central portions 12 is provided with a plurality of ribs 122.

At least two filter cloths 40 are respectively coupled to the corresponding side of each filter plate 10 Each of the filter cloths 40 has a cloth hole 41 corresponding to the through hole 121.

Referring to the first to third figures, each of the filter plates 10 is selectively combined to make Each of the perforations 121 is opposite, and a filter chamber 30 communicating with the outside is formed between the central portions 12 of each of the filter plates 10. Each of the perforations 121 provides a slurry flow through which the mud is deposited in the filter chamber 30, and each filter cloth 40 is filtered, and the stability and pressure resistance of the center portion are improved by the plate body 13 provided in the center portion 12, and deformation and damage are not caused by the mud pushing.

The liquid in the mud flows through the first drain pipe through each of the through holes 21 111.

After the initial filtration, the pressing pressure of the relative combination of the filter plates 10 can be further increased. The force causes the plate frame 11 of each filter plate 10 to be elastically compressed again, thereby pressing out the residual moisture in the mud cake and increasing the degree of the mud biscuit.

When the filter plate 10 is separated, the mud cake stuck in the filter chamber 30 can be removed.

Please refer to the fourth figure, which is a second embodiment of the present invention, due to the main structure filter plate The plate frame 11 and the center portion 12 of the first embodiment are the same as those of the first embodiment, and therefore the same portions will not be described again, and only the differences will be described below.

In the embodiment, the plate frame 11 is axially provided with a plurality of second drainage pipes 112. The through holes 21 of the class portion 20 are respectively connected to the second liquid discharge pipe 112. When filtering, the filter plates 10 are combined to make the respective through holes 121 and the second liquid discharge pipes 112 relatively communicate with each other. A filter chamber 30 is formed between the central portions 12, and each of the through holes 121 provides a slurry flow through, so that the mud is deposited in the filter chamber 30, and is filtered by each filter cloth 40, so that the fluid in the mud is again separated by the through holes 21 respectively. The flow passes through the second drain conduit 112.

Moreover, in practice, the first drain conduit 111 and the second drain conduit 112 can also Simultaneously disposed on the filter plate, each of the first drain pipes 111 communicates with the lower through hole 21, and the second drain pipe 112 communicates with the upper through hole 21, so that the filter plate 10 has two kinds of draining modes at the same time. .

The above detailed description is specific to one of the possible embodiments of the present invention, The examples are not intended to limit the scope of the invention, and the equivalents of the embodiments of the invention are intended to be included in the scope of the invention.

In summary, the present invention has achieved the breakthrough under the prior art structure. It is easy to think about the effect of the person who is not familiar with the art. Moreover, the invention has not been disclosed before the application, and its progressiveness and practicability have been consistent with the application requirements of the invention patent. For the application of the invention, you are requested to approve the application for the invention patent of this invention, so as to encourage the invention, and to the sense of virtue.
