Description

Technical Field

[0001] This utility model belongs to the technical field of solid-liquid separation and filtration equipment, specifically relating to a bidirectional rapid feeding filter plate. Background Technology

[0002] Chamber filter presses are key equipment for solid-liquid separation in chemical, mining, environmental protection, food, and hazardous waste treatment industries. Traditional filter presses generally use a center-feed method, which has the following inherent drawbacks: First, the filter cloth must be threaded through the feed hole in the center of the filter plate, making the installation and replacement process cumbersome, time-consuming, and labor-intensive. Secondly, when using a large-area filter plate with a single-point feed in the center, the material has a long path to the edge of the filter chamber and high resistance, which can easily lead to uneven feed pressure distribution, slow filter cake formation and uneven thickness, resulting in low overall filtration efficiency, especially for materials with low solids content. Furthermore, the sealing of the feed inlet often relies on rigid contact, which is prone to wear and leakage under long-term high pressure and corrosive materials, affecting the filtration effect and creating safety hazards.

[0003] Therefore, developing a filter plate structure that can achieve rapid and uniform feeding and reliable sealing is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model discloses a bidirectional rapid feeding filter plate, and specifically discloses the following technical solutions: A bidirectional rapid feeding filter plate includes a filter plate body. Filter chambers are respectively provided on both sides of the filter plate body. A mesh filtrate groove is provided on the bottom surface of each filter chamber. A manifold is provided inside the filter plate body around the filter chambers, and the manifold is connected to the filter chambers via several manifold holes. A drain outlet connected to the manifold is provided at the corner of the filter plate body. Feed holes penetrating the filter plate body are respectively provided on both sides of the filter chambers at the upper part of the filter plate body. Feed channel holes penetrating the filter plate body are respectively provided on both sides of the filter chambers at the lower part of the filter plate body. A feed shoe is installed in each feed hole, and the feed shoe is used to guide the filtrate in the feed hole into the filter chambers.

[0005] Furthermore, the feed shoe includes an mounting cylinder and a guide groove. The mounting cylinder is installed inside the feed hole. The two ends of the mounting cylinder are respectively connected to the guide groove on the side near the filter press chamber. A receiving groove is provided on the surface of the filter plate body below each guide groove for accommodating the guide groove.

[0006] Furthermore, the feed shoe is made of fluororubber, and the end of the feed guide groove near the filter press chamber is bent upwards.

[0007] Furthermore, a number of support protrusions are evenly arranged on the bottom surface of the filter press chamber.

[0008] Furthermore, the filter plate body has annular mounting grooves at both ends of the feed channel hole, and a sealing ring is installed in the annular mounting groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: The bidirectional feeding design greatly shortens the material flow path, reduces flow resistance, and increases the feeding speed under the same pumping power.

[0010] The feed shoe, made of fluororubber, is used as a sealing element. Its excellent elasticity, wear resistance and high temperature resistance ensure the sealing reliability of the feed hole under long-term high pressure operation and reduce the risk of leakage.

[0011] The side-feed method eliminates the need for the filter cloth to be perforated in the center, simplifying the installation and removal process, making filter cloth replacement more convenient and quick, and reducing maintenance costs and downtime.

[0012] The combination of the mesh filtrate tank and the four-corner concealed drainage system ensures that the filtrate can be quickly collected and discharged, avoiding the extension of the filtration cycle caused by filtrate retention, and improving the overall filtration efficiency and dehydration effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-7 A bidirectional rapid feeding filter plate includes a filter plate body 1, with filter pressing chambers 2 respectively provided on both sides of the filter plate body 1, and a mesh filtrate trough 4 provided on the bottom surface of the filter pressing chamber 2. A manifold 12 is provided inside the filter plate body 1 around the filter pressing chamber 2, and the manifold 12 is connected to the filter pressing chamber 2 through a plurality of manifold holes 11. A drain outlet 5 connected to the manifold 12 is provided at the corner of the filter plate body 1. Feed holes 6 penetrating the filter plate body 1 are provided on both sides of the filter pressing chamber 2 at the upper part of the filter plate body 1, and feed channel holes 9 penetrating the filter plate body 1 are provided on both sides of the filter pressing chamber 2 at the lower part of the filter plate body 1. A feed shoe 7 is installed in the feed hole 6, and the feed shoe 7 is used to guide the filtrate in the feed hole 6 into the filter pressing chamber 2.

[0023] In this embodiment, the feed shoe 7 includes an installation cylinder and a guide groove 8. The installation cylinder is installed in the feed hole 6. The two ends of the installation cylinder are respectively connected to the guide groove 8 on the side near the filter press chamber 2. A receiving groove is provided on the surface of the filter plate body 1 below each guide groove 8 to receive the guide groove 8.

[0024] In this embodiment, the feed shoe 7 is made of fluororubber, and the end of the guide groove 8 near the filter press chamber 2 is bent upward.

[0025] In practical applications, several filter plates from this invention need to be stacked and combined. When several filter plates are pressed together in sequence, the feed channel holes 9 at the bottom of all adjacent filter plates are aligned, forming a sealed straight pipe feed channel that runs through the entire filter plate assembly. The front end of this channel can be connected to the feed pipe of the filter press, and the rear end is connected to the feed hole 6 at the top of the filter plate through a branch channel to form a loop channel. The feed hole 6 of the filter plate assembly is connected to form the first feed channel, and the feed channel holes 9 of the filter plate assembly are connected to form the second feed channel, realizing rapid feeding from both ends of the filter plate assembly, greatly shortening the distance of material transportation to each filter chamber, making the pressure distribution more uniform, and significantly improving the feeding speed.

[0026] When installing the filter cloth, it is first placed over the surface of the filter plate, with the edge of the filter cloth passing through the gap between the curved part of the guide groove 8 and the filter plate body 1. During plate assembly, the curved part of the guide groove 8 is flattened by force, pressing the filter cloth into the receiving groove, thus both fixing the filter cloth and forming a high-pressure seal. After assembly, a pressure filtration space is formed between the filter cloths, and the feed shoes 7 of adjacent filter plates are pressed together, connecting the feed hole 6 and the pressure filtration chamber 2 through the guide groove 8. The feed shoe 7 is not only part of the feed channel but also a highly efficient elastic sealing device.

[0027] To further address the issue of residual material, a venting device can be installed on the feed pipe connected to the feeding channel. This venting device can be a compressed air pump. After feeding is complete, close the feed valve and open the venting valve to allow compressed air or other harmless gases to be introduced, blowing out any residual material from the feeding channel and its feed pipe in the reverse direction. This cleans and vents the channel, preventing blockages and cross-contamination.

[0028] In this embodiment, the filter plate body 1 is integrally processed from reinforced homopolymer polypropylene material, which has excellent characteristics such as corrosion resistance, high strength, wide operating temperature range, lightweight and environmental protection and non-toxicity.

[0029] In this embodiment, a number of support protrusions 3 are evenly arranged on the bottom surface of the filter press chamber 2 to support the filter cloth and provide support when the plate is pressed together, so as to prevent the filter plate from deforming.

[0030] In this embodiment, annular mounting grooves are respectively opened on the outer periphery of both ends of the feed channel hole 9 on the filter plate body 1, and sealing rings 10 are installed in the annular mounting grooves to improve the sealing performance and prevent leakage.

[0031] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
