[0002] The plate and frame filter press is a key equipment for achieving solid-liquid separation in the production process of water purifiers. In the production process of water purifiers, when a suspension containing solid particles is pumped into the filter chamber of the plate and frame filter press, the solid particles are retained by the filter cloth in the filter chamber between the plates and frames to form a filter cake, while the filtered liquid flows out through the liquid outlet pipe between the filter cloth and the filter plate. The plate and frame filter press can effectively separate solid particles from liquid in the production process of water purifiers through its special filtering mechanism.

[0003] A Chinese invention patent with application number CN221112357U discloses a highly efficient and environmentally friendly industrial wastewater treatment device, which includes a frame and a filter press device, wherein the filter press device includes a brake plate mounted on the frame, a plurality of filter plates and a pull plate assembly.

[0004] The pull plate assembly in the existing filter press device includes multiple components such as a pawl, a dial, a lever, and a crowbar on the filter plate. The complex mechanical structure of the pull plate assembly not only increases the cost, but also during long-term use, the wear of the components may affect the overall operation effect, resulting in the filter plate opening and movement being not smooth. In addition, due to the complex structure of the pull plate assembly, when a failure occurs or maintenance is required, technicians need to spend more time to disassemble, inspect and replace components, resulting in a long maintenance time, which affects the production efficiency of the filter press.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model proposes a filter press device for producing water purifiers, including a frame 4, a brake plate 1 is installed at one end of the frame 4, and a drive seat 7 is installed at the other end. A plurality of filter plates 5 are arranged between the brake plate 1 and the drive seat 7, and the drive seat 7 is driven and connected to a dynamic pressure plate 6 for cooperating with the brake plate 1 to press the plurality of filter plates 5 together. The top ends of the plurality of filter plates 5 are all fixed with shifting blocks 54 protruding from the top end faces of the filter plates 5. The shifting blocks 54 are provided with driving inclined surfaces 541 on both sides along the length direction. After the plurality of filter plates 5 are pressed together, the driving inclined surfaces 541 between two adjacent shifting blocks 54 cooperate to form a driving groove 542. A plate separation mechanism 8 which can move downward to squeeze the driving groove 542 to separate the two adjacent filter plates 5 is installed above the brake plate 1 and the drive seat 7, and a wedge block 84 for squeezing the driving groove 542 is installed on the plate separation mechanism 8.

[0023] In the embodiment, the plate separation mechanism 8 includes a driving cylinder 83 that can slide above the brake plate 1 and the driving seat 7. The bottom of the driving cylinder 83 is provided with an output end that can be extended and retracted in the vertical direction, and a wedge block 84 is fixedly installed at the bottom of the output end.

[0024] In the embodiment, the cross-section of the wedge block 84 matches the cross-section of the driving groove 542 .

[0025] In the embodiment, the plate separation mechanism 8 also includes a slide rail 82 horizontally fixed above the brake plate 1 and the drive seat 7, a motor 81 is provided at one end of the slide rail 82, a slider is provided on the slide rail 82 and is driven by the motor 81 to slide along the slide rail 82, and a driving cylinder 83 is installed at the front end of the slider.

[0026] In the embodiment, side plates 2 for mounting a plurality of filter plates 5 are provided on both sides of the brake plate 1 and the driving seat 7 , and the plurality of filter plates 5 are slidably connected to the side plates 2 .

[0027] In the embodiment, brackets 51 are installed on the front and rear side walls of the non-pressed surfaces of several filter plates 5, and sliding wheels 52 perpendicular to the setting direction of the brackets 51 are installed at one end of the bottom of the brackets 51 on both sides. The filter plates 5 are slidably connected to the top end surfaces of the side plates 2 through the sliding wheels 52 on both sides.

[0028] In the embodiment, the bottom ends of the front and rear side walls of the non-pressed surfaces of the filter plates 5 are also provided with a liquid outlet pipe 53 connected to the inside of the filter plates 5, and the frame 4 is located below the liquid outlet pipe 53 and is correspondingly provided with a collection tank 3

[0029] In the embodiment, the collecting tank 3 is detachably fixed on the frame 4 .

[0030] In the embodiment, sealing rings are provided on the outer circles of both end surfaces of the pressed filter plates 5 .

[0031] The working principle of the filter press device for water purification agent production based on the first embodiment is as follows: a brake plate 1 is installed at one end of the frame 4, and a drive seat 7 is installed at the other end. The drive seat 7 is driven and connected to a dynamic pressure plate 6. A plurality of filter plates 5 are placed between the brake plate 1 and the dynamic pressure plate 6. Side plates 2 are also provided at both ends of the length direction of the frame 4. The filter plates 5 are slidably connected to the side plates 2 through a bracket 51 and a sliding wheel 52 installed at the bottom of the bracket 51. Sealing rings are provided on the outer ring surfaces of the two end faces of the filter plates 5 that are pressed together to ensure the close contact between the brake plate 1 and the filter plates 5, the filter plates 5 and the adjacent filter plates 5, and the filter plates 5 and the dynamic pressure plates 6 during the pressing process. Sealing; when the filter plate 5 is installed, the dynamic pressure plate 6 moves toward the brake plate 1 under the drive of the driving seat 7, and all the filter plates 5 arranged between the brake plate 1 and the dynamic pressure plate 6 are pressed together to form an internally interconnected whole, so that the water purifier raw material is introduced into the space between several adjacent filter plates 5 for filtration. During the filtration process, the solid particles in the water purifier are trapped by the space between the two filter plates 5, and the filtrate flows out from the liquid outlet pipes 53 at the bottom of the front and rear sides of the filter plate 5 and flows into the corresponding collection tank 3 under the frame 4. The collection tank 3 is designed to be detachable, which is convenient for the collection, transfer and treatment of the filtrate.

[0032] When the filtration process is completed and several filter plates 5 need to be separated, the motor 81 on the plate separation mechanism 8 drives the slider on the slide rail 82 to slide, driving the driving cylinder 83 installed at the front end of the slider to move, so that the driving cylinder 83 moves to the top of the filter plate 5, and the driving cylinder 83 drives the output end to extend in the vertical direction, so that the wedge block 84 fixedly installed on the output end moves downward to squeeze the driving groove 542 formed between the two shifting blocks 54 at the top of the two adjacent filter plates 5. Since the cross-section of the wedge block 84 coincides with the cross-section shape of the driving groove 542, the wedge block 84 can smoothly enter the driving groove 542, and the driving groove 542 is composed of two inclined driving inclined surfaces 541. The wedge block 84 continues to be pressed down under the driving action of the driving cylinder 83, so that the driving inclined surfaces 541 on both sides of the driving groove 542 are subjected to a horizontal driving force perpendicular to the downward pressure direction of the wedge block 84, thereby driving the two adjacent filter plates 5 to separate. After several filter plates 5 are separated, the solid matter in the filter plate 5 is taken out, and the filter plate 5 is cleaned to remove the residue.

[0033] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
