Problems solved by technology

[0004] The disadvantages of the above-mentioned background technology: one is that the material of the diaphragm does not meet the requirements of the food hygiene industry, especially in the production of wine, whether it is a rubber diaphragm, a composite rubber diaphragm, or a PP diaphragm, it directly affects the taste of the wine. Adverse effects; the second is that due to the poor elasticity of the rubber diaphragm, composite rubber diaphragm, and PP diaphragm itself, not only the sealing performance between the supporting plate core is poor, but also the sealing performance between the filter plate and the filter plate is poor. In order to achieve a reliable seal between the diaphragm and the plate core, and between the diaphragm and the filter plate, many technical solutions have been adopted, but due to the lack of flatness and proper Elasticity, the result is often unsatisfactory, and

Example Embodiment

[0021] Example 1: Refer to the attached image 3 . The diaphragm for an air chamber filter press, which includes a diaphragm, means that on the basis of the existing diaphragm, the diaphragm is a sheet-shaped silica gel diaphragm 1 and the four corners of the sheet-shaped silica gel diaphragm 1 are provided with convex liquid outlet channels 5 and convex There is a convex type air passage 3 between the convex type washing liquid channel 2 and the convex type washing liquid channel 2. The convex air passages 2 in the sheet-shaped silicone diaphragm 1 are one or more than one and are located on the sealing surface of the sheet-shaped silicone diaphragm. The sheet-shaped silica gel diaphragm 1 has no edges around it. The center of the sheet-like silicone diaphragm is the feed port 19.

Example Embodiment

[0022] Example 2: Refer to the attached Figure 7 with 8 . A diaphragm for an air chamber filter press, which includes a diaphragm, and is characterized in that: a high-strength cloth 20 or a mesh cloth or a net or a plate is built around the inlet 19 and the liquid outlet 4 of the sheet-like silica gel diaphragm 1 The core 6 faces the boss 7 faces the sheet-like silicone diaphragm opposite to the high-strength cloth 21 or mesh cloth or net on the back, or the sheet-like silicone diaphragm 1 has a built-in high-strength cloth 20 or around the inlet 19 and the liquid outlet 4 A high-strength cloth 21 or a net cloth or a net is placed on the back of the mesh cloth or net, and the sheet-like silicone membrane opposite to the boss 7 surface of the core surface 6.

Example Embodiment

[0023] Example 3: Refer to the attached Figure 4 . The plate core for the air chamber filter press, which includes a plate core, means that on the basis of the existing plate core, the sealing surface of the plate core 6 is provided with air holes 9 and communicates with the core cavity 10 of the plate core 6 ( There are channels 14), the plate core 6 is provided with a convex type washing liquid channel 2 and a convex type liquid outlet channel 5. The core surface of the plate core 6 is provided with three or more bosses 7 and the bosses 7 are distributed on the plate core 6 Around the liquid inlet. The board core sealing surface 11 in the board core 6 is lower than the boss 7 surface and any value within the range of 2-6 mm, including the end value. The board core surface in the board core 6 has no bumps.

Abstract

The invention relates to an air chamber-type press filter-used diaphragm plate, which comprises a diaphragm plate, wherein the diaphragm in the diaphragm plate is of the flaky silicon gel diaphragm; the back surfaces of the four corners of the flaky silicon gel diaphragm are provided with a boss-type liquid out passage and a boss-type liquid washing passage; a boss-type air passage is arranged between the boss-type liquid out passage and the boss-type liquid washing passage; a sealing surface of a plate core of the diaphragm plate is provided with an air hole that is communicated with a core cavity of the plate core; the plate core is provided with a boss-type liquid washing passage and a boss-type liquid out passage; the core surface of the plate core is provided with three or more than three bosses that are distributed around a liquid inlet of the plate core; and the boss-type liquid out passage, the boss-type liquid washing passage and the boss-type air passage are respectively spliced and matched with a liquid outlet, a liquid washing hole and the air hole that are arranged on the surface of the plate core. The air chamber-type press filter-used diaphragm plate has the advantages that: 1, the adverse effect to the mouthfeel of wine can not be caused; 2, the sealing is reliable, and the corrosion resistance is good; 3, the extrusion deformation between a filter plate and the diaphragm can be avoided, and the diaphragm can be prevented from being broken due to the extrusion; 4, the hidden air passage can not consume material and does not have trouble.

Description

technical field [0001] The invention relates to a diaphragm plate for an air box filter press which has good elasticity, does not make the diaphragm hard and brittle, and has the function of embossing a convex liquid outlet hole and an air hole, and belongs to the field of diaphragm plate manufacturing. Background technique [0002] CN2552579Y, name "diaphragm filter press converted from ordinary air chamber filter press", replaces the filter plate on the ordinary air chamber filter press with the filter plate spaced by the filter plate with diaphragm on both sides with air-filled holes on the side , Install a compressed air main pipe with branches equal to the number of diaphragm filter plates along the side of the air filling hole, and use high-pressure hoses to connect the air filling holes on the diaphragm filter plate with the branch pipes on the compressed air main pipe one by one , according to more economical and practical means, the advanced membrane filter press te...
