Description

Technical Field

[0001] The utility model relates to the technical field of filter cloth replacement of a filter press, in particular to a sewage and sludge filter press for quickly replacing filter cloth. Background Technique

[0002] A sewage and sludge filter press is a device specifically used for sludge dewatering in the wastewater treatment process of urban sewage treatment plants, pharmaceutical, electroplating, papermaking, leather, printing and dyeing, metallurgy, chemical industry, slaughtering, food, brewing and environmental protection projects. Its main purpose is to achieve filtration through the application of mechanical force, that is, the process of solid-liquid separation. When the filter press is in use, its filter cloth needs to be replaced regularly to make the filtration effect better.

[0003] As disclosed in a filter press for facilitating filter cloth replacement in Chinese Patent CN220385881U, the limit sliding design of the sliding seat and the sliding cavity and the matching design of the fixed pin and the clamping pin, through the connection design between the outer circumference of the fixed pin and the limiting plate and the elastic restoring force of the compression spring, can further make the fixed pin and the clamping pin maintain the clamped position to achieve fixation. Then, through the design of the pull handle and the concave pulling part of the pull handle, pulling the pull handle can separate the opening pin from the fixed pin, further facilitating the disassembly and assembly of the filter press plate. The concave design of the filter press plate and the pressing and clamping design of the pressing frame, through the threaded connection design of the threaded rod and the threaded sleeve and the connection design of the threaded sleeve and the pressing frame, and then through the meshing design of the driving bevel gear and the driven bevel gear and the connection design of the driven bevel gear and the threaded rod, when the driving rod is rotated, the threaded rod can be further rotated, driving the movement of the pressing frame, realizing the pressing and fixing design of the filter cloth, and playing a role in facilitating the disassembly and assembly of the filter cloth.

[0004] For this structure, although the filter cloth can be disassembled and replaced, it is necessary to remove the used filter cloth and then install the new filter cloth, and the operation is cumbersome. Therefore, we propose a sewage and sludge filter press for quickly replacing filter cloth that can synchronously disassemble the old filter cloth and install the new filter cloth to make the filter cloth replacement more convenient. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sewage and sludge filter press for quickly replacing filter cloth to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sewage and sludge filter press for quickly replacing filter cloth, including a base, a water collecting tank is fixedly installed on the top surface of the base, a vertical frame is arranged outside the water collecting tank, a filter cloth is arranged inside the vertical frame, and a processing component is arranged above the base. The processing component includes a disassembly and assembly component arranged above the base, and a filter pressing component is arranged outside the disassembly and assembly component.

[0007] Preferably, the disassembly and assembly component includes a mounting plate fixedly installed on the outer wall of the filter cloth. A limiting groove is formed inside the mounting plate. A sliding frame is slidably arranged inside the limiting groove. A sliding column is fixedly installed inside the sliding frame. A clamping pin is slidably arranged on the outer wall of the sliding column. An inclined groove is formed on the outer wall of the clamping pin. A spring is fixedly installed at one end of the sliding frame. An I-shaped frame is slidably arranged inside the mounting plate. A clamping groove is formed at the bottom of the I-shaped frame.

[0008] Preferably, the pressure filtration component includes a cylinder fixedly installed on the top surface of the vertical frame. A frame is fixedly installed at the end of the cylinder away from the vertical frame. A sliding plate is fixedly installed on the outer wall of the frame. An extrusion column is slidably arranged inside the sliding plate. A fixing plate is fixedly installed at the end of the extrusion column. A conveying pipe is communicatively arranged inside the frame. A limiting rod is fixedly installed on the outer wall of the vertical frame. A limiting block is slidably arranged on the outer wall of the limiting rod.

[0009] Preferably, the inclined groove is inclined. The clamping pin is clamped with the clamping groove. The mounting plate and the I-shaped frame are slidably arranged. Under its limitation, when the clamping pin is aligned with the clamping groove, the spring can be pushed to move the sliding frame, so that the outer wall of the sliding column slides and presses against the inner wall of the inclined groove, and the clamping pin is clamped with the clamping groove.

[0010] Preferably, one end of the spring is fixedly installed on the outer wall of the sliding frame, and the other end of the spring away from the sliding frame is fixedly installed on the inner wall of the limiting groove. Under the limitation of the spring, the clamping pin can be stably clamped with the clamping groove, avoiding the filter cloth from falling off during pressure filtration.

[0011] Preferably, there are two sliding plates, which are symmetrically distributed with respect to the center line of the top surface of the base. Under the limitation of the inclined sliding grooves formed on the outer walls of the sliding plates, the extrusion columns can be centered and gathered for pressure filtration.

[0012] Preferably, the limiting block is fixedly installed on the top surface of the I-shaped frame, and the end of the limiting rod is fixedly installed on the inner side of the vertical frame. Under its limitation, when the sliding plate slides on the outer wall of the extrusion column, the extrusion columns can be centered and gathered.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The sewage and sludge filter press with quick filter cloth replacement has a disassembly and assembly component as one of its parts. When the filter cloth of the filter press needs to be replaced, slide the mounting plate fixedly installed on the outer wall of the new filter cloth into the inside of the I-shaped frame. Extrude the sliding frame slidably arranged inside the I-shaped frame of the old filter cloth with the outer wall of the I-shaped frame fixedly installed above the new filter cloth, so that the sliding frame slides into the inside of the mounting plate, and the sliding column fixedly installed on the inner side of the sliding frame slides accordingly. Since the outer wall of the sliding column slides with the inner wall of the inclined groove opened on the outer wall of the pin, under its restriction, when the sliding column moves towards the spring direction, its outer wall presses against the inner wall of the inclined groove, causing the pin to slide into the inside of the limit groove, so that the pin no longer engages with the card slot opened at the bottom of the I-shaped frame. At this time, press the sliding frame above the new filter cloth to make the pin in a horizontal state inside the mounting plate, and push the new filter cloth into the inside of the I-shaped frame. The new filter cloth will push the old filter cloth towards the outside of the I-shaped frame. When the new pin slides to the inside of the I-shaped frame, at this time, the operator releases the sliding frame and just pushes the new filter cloth into the inside of the I-shaped frame. When the pin aligns with the card slot, under the elastic action of the spring, push the sliding frame towards the side away from the old filter cloth, so that the sliding column fixedly installed on the inner side of the sliding frame contacts and presses against the inner wall of the inclined groove, causing the pin to slide into the inside of the card slot to engage the new filter cloth with the I-shaped frame to achieve the installation effect. At this time, just pull out the old filter cloth from the inside of the I-shaped frame. This structure can quickly replace the filter cloth, and the engagement of the pin and the card slot can prevent the operator from tightening the filter cloth.

[0015] 2. The sewage and sludge filter press with quick filter cloth replacement has a filter pressing component as one of its parts. When sewage and sludge need to be filter pressed, convey it into the filter cloth through the conveying pipe. At this time, start the air cylinder, which pushes the frame upward. The frame drives the sliding plate to move upward accordingly, so that the inner wall of the inclined sliding groove opened on the outer wall of the sliding plate presses against the outer wall of the extrusion column. Under the restriction of the limit rod, the limit block fixedly installed on the top surface of the I-shaped frame slides on the outer wall of the limit rod, causing the extrusion column to drive the fixed plate to gather in the center. The fixed plate drives the I-shaped frame to move accordingly, and the I-shaped frame drives the filter cloth below to gather. Carry out the filter pressing work through the pressing plates arranged on the outer walls of the two sides of the filter cloth, and then collect the filter pressed water by the water collecting tank.

[0023] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] A preferred embodiment of a sewage and sludge pressure filter with a quick filter cloth replacement provided by the present utility model is as Figures 1 to 6 shown: A sewage and sludge pressure filter with a quick filter cloth replacement, including a base 1;

[0026] A water collecting tank 2 is fixedly installed on the top surface of the base 1;

[0027] An upright frame 3 is arranged outside the water collecting tank 2;

[0028] A filter cloth 4 is arranged inside the upright frame 3;

[0029] And a processing component 5 arranged above the base 1. The processing component 5 includes a disassembly and assembly component 51 arranged above the base 1. The disassembly and assembly component 51 includes a mounting plate 511 fixedly installed on the outer wall of the filter cloth 4. A limiting groove 512 is opened inside the mounting plate 511. A sliding frame 513 is slidably arranged inside the limiting groove 512. A sliding column 514 is fixedly installed inside the sliding frame 513. A pin 515 is slidably arranged on the outer wall of the sliding column 514. An inclined groove 516 is opened on the outer wall of the pin 515. A spring 517 is fixedly installed at one end of the sliding frame 513. An I-shaped frame 518 is slidably arranged inside the mounting plate 511. A card slot 519 is opened at the bottom of the I-shaped frame 518.

[0030] In this embodiment, when the filter cloth 4 of the filter press needs to be replaced, the mounting plate 511 fixedly installed on the outer wall of the new filter cloth 4 is slid into the I-shaped frame 518, so that the outer wall of the I-shaped frame 518 fixedly installed above the new filter cloth 4 presses against the sliding frame 513 slidably arranged inside the I-shaped frame 518 in the old filter cloth 4, causing the sliding frame 513 to slide into the mounting plate 511. The sliding column 514 fixedly installed inside the sliding frame 513 slides accordingly. Since the outer wall of the sliding column 514 is slidably arranged on the inner wall of the inclined groove 516 opened on the outer wall of the pin 515, under its restriction, when the sliding column 514 moves towards the spring 517, its outer wall presses against the inner wall of the inclined groove 516, causing the pin 515 to slide into the limiting groove 512, so that the pin 515 no longer engages with the card slot 519 opened at the bottom of the I-shaped frame 518. At this time, press the sliding frame 513 above the new filter cloth 4 to make the pin 515 in a horizontal state inside the mounting plate 511, and push the new filter cloth 4 into the I-shaped frame 518. The new filter cloth 4 pushes the old filter cloth 4 towards the outside of the I-shaped frame 518. When the new pin 515 slides into the I-shaped frame 518, at this time the operator releases the sliding frame 513 and just pushes the new filter cloth 4 into the I-shaped frame 518. When the pin 515 aligns with the card slot 519, under the elastic action of the spring 517, the sliding frame 513 is pushed towards the side away from the old filter cloth 4, so that the sliding column 514 fixedly installed inside the sliding frame 513 contacts and presses against the inner wall of the inclined groove 516, causing the pin 515 to slide into the card slot 519 to engage the new filter cloth 4 with the I-shaped frame 518 to achieve the installation effect. At this time, just pull out the old filter cloth 4 from inside the I-shaped frame 518. This structure can quickly replace the filter cloth 4, and the engagement of the pin 515 with the card slot 519 can prevent the operator from fastening the filter cloth 4.

[0031] Further, the inclined groove 516 is inclined. The pin 515 engages with the card slot 519, and the mounting plate 511 is slidably arranged with the I-shaped frame 518. Under its restriction, when the pin 515 aligns with the card slot 519, the spring 517 can push the sliding frame 513, so that the outer wall of the sliding column 514 slides and presses against the inner wall of the inclined groove 516, causing the pin 515 to engage with the card slot 519.

[0032] Furthermore, one end of the spring 517 is fixedly installed on the outer wall of the sliding frame 513, and the end of the spring 517 away from the sliding frame 513 is fixedly installed on the inner wall of the limiting groove 512. Under the restriction of the spring 517, the pin 515 can be stably engaged with the card slot 519 to prevent the filter cloth 4 from falling off during pressure filtration.

[0033] Embodiment 2

[0034] On the basis of Embodiment 1, a preferred embodiment of a sewage and sludge filter press for quickly replacing the filter cloth provided by the present utility model is as follows Figures 1 to 6As shown in the figure: The filter press assembly 52 includes a cylinder 521 fixedly installed on the top surface of the vertical frame 3. One end of the cylinder 521 away from the vertical frame 3 is fixedly installed with a frame 522. The outer wall of the frame 522 is fixedly installed with a slide plate 523. An extrusion column 524 is slidably arranged inside the slide plate 523. One end of the extrusion column 524 is fixedly installed with a fixing plate 525. A conveying pipe 526 is communicatively arranged inside the frame 522. A limiting rod 527 is fixedly installed on the outer wall of the vertical frame 3. A limiting block 528 is slidably arranged on the outer wall of the limiting rod 527.

[0035] In this embodiment, when it is necessary to filter the sewage sludge, it is conveyed into the filter cloth 4 through the conveying pipe 526. At this time, the cylinder 521 is started, which pushes the frame 522 to move upward. The frame 522 drives the slide plate 523 to move upward accordingly, so that the inner wall of the inclined chute opened on the outer wall of the slide plate 523 extrudes the outer wall of the extrusion column 524. Under the restriction of the limiting rod 527, the limiting block 528 fixedly installed on the top surface of the I-shaped frame 518 slides on the outer wall of the limiting rod 527, so that the extrusion column 524 drives the fixing plate 525 to gather in the middle, and the fixing plate 525 drives the I-shaped frame 518 to move accordingly, so that the I-shaped frame 518 drives the filter cloth 4 below to gather. The filter press work is carried out through the pressing plates arranged on the outer walls of the two sides of the filter cloth 4, and then the filter press water is collected by the water collecting tank 2.

[0036] Furthermore, there are two slide plates 523, which are symmetrically distributed with respect to the center line of the top surface of the base 1. Under the restriction of the inclined chutes opened on the outer walls of the slide plates 523, the extrusion columns 524 can gather in the middle for filter pressing.

[0037] In addition, the limiting block 528 is fixedly installed on the top surface of the I-shaped frame 518, and the end of the limiting rod 527 is fixedly installed on the inner side of the vertical frame 3. Under its restriction, when the slide plate 523 slides on the outer wall of the extrusion column 524, the extrusion column 524 can gather in the middle.

[0038] The above is only a schematic specific embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the various components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be used alone according to actual needs or selected in combination. Therefore, the present invention should reasonably cover other combinations and specific applications related to the inventive points of this case.
