Description

Filter plate set

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

According to the filter plate set installed on the conventional filter press, each filter plate and filter cloth in the filter plate group are selectively combined according to the action 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. Therefore, 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 comprises: 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 having Elastic, and a first liquid discharge pipe is arranged on both end faces of the plate frame, and a plurality of second liquid discharge pipes are arranged in the axial direction of the plate frame; the central portion is recessed in the plate frame, and at least one perforation is arranged on the central portion There is a class part between the plate frame and the central part, and the plurality of through holes communicating with the first drainage pipe and each of the second drainage pipes are respectively arranged on the class part, and the filter plates are combined at the time of filtration so that the perforations are relatively And a filter chamber communicating with the outside is formed between the central portions of each filter plate, each perforation system provides mud circulation, so that the mud is deposited in the filter chamber, and is filtered by each filter cloth, so that the fluid in the mud is separated from each through hole Flow through the first drain conduit and the second drain conduit.

The main purpose of the filter plate set of the present invention is to combine the filter plates with elastic plate frames. The sealing degree is higher, and a plurality of ribs are arranged on the filter plate, which can more effectively filter and drain the liquid, remove the mud cake, and improve the degree of the mud biscuit.

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, which are described in detail below. Referring to the first and second figures, the first embodiment of the filter plate set 1 of the present invention An 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 the present embodiment, it is elastic on the outer side of the plate frame 11), and a first liquid discharge pipe 111 is respectively disposed on both end faces of the plate frame 11.

The central portion 12 is recessed in the plate frame 11, and the central portion 12 is respectively provided with at least one through hole 121. The plate frame 11 and the central portion 12 have a step portion 20, and the class portion 20 is respectively provided with a plurality of first and second portions. The drain 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 sides of the filter plates 10, and each filter cloth 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 combined at the time of filtration so that the perforations 121 are opposed to each other, and a filter chamber 30 communicating with the outside is formed between the central portions 12 of the filter plates 10, and each of the perforations 121 is The mud is passed through, the mud is deposited in the filter chamber 30, and filtered by each filter cloth 40, so that the fluid in the mud is again discharged from the through holes 21 through the first drain pipe 111.

After the initial filtration, the pressing pressure of the relative combination of the filter plates 10 can be further increased, so that the plate frame 11 of each filter plate 10 is elastically compressed again, thereby pressing out the residual moisture in the mud cake. Increase the degree of mud cookies.

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

Please refer to the fourth embodiment, which is a second embodiment of the present invention. Since the frame 11 and the central portion 12 of the main structure filter plate 10 are the same as those of the first embodiment, the same portions will not be described again. Only the differences will be described below. First described.

In the present embodiment, the plate frame 11 is axially provided with a plurality of second liquid discharge pipes 112, and the through holes 21 of the class portion 20 are respectively communicated with the second liquid discharge pipe 112. When filtering, the filter plates 10 are combined. Corresponding to each of the perforations 121 and the second drainage conduits 112, a filter chamber 30 is formed between the central portions 12 of each of the filter plates 10. Each of the perforations 121 provides a slurry flow through the slurry chamber 30 for depositing mud in the filter chamber 30. And filtered by each filter cloth 40, so that the fluid in the mud is again discharged from each of the through holes 21 through the second liquid discharge pipe 112.

In addition, in the implementation, the first drain pipe 111 and the second drain pipe 112 can also be disposed on the filter plate at the same time, and each of the first drain pipes 111 communicates with the lower through hole 21, and the second drain pipe 112 Then, it communicates with the upper through hole 21, so that the filter plate 10 has two kinds of liquid discharge modes at the same time.

The detailed description of the present invention is intended to be illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention. In the scope of patents.

In summary, the present invention has achieved the desired effect under the prior art structure, and is not easily understood by those skilled in the art. Furthermore, the present invention has not been disclosed before the application, and it has The progressiveness and practicability have been consistent with the application requirements of the invention patent, and the application for invention is filed according to law. You are requested to approve the application for the invention patent to encourage the invention.
