Description

Technical Field

[0001] This utility model relates to a filter cloth cleaning device and its filter press, belonging to the technical field of solid-liquid separation equipment. Background Technology

[0002] Filter presses, as core equipment for solid-liquid separation, are widely used in chemical, mining, environmental protection, and food industries. Filter cloth is a key component in filter presses for achieving solid-liquid separation, and its cleanliness directly affects filtration efficiency and filter cake moisture content. Most existing filter cloth cleaning devices for filter presses move along the slide under the traction of the plate puller, and then clean the filter cloth on each filter plate in turn. During use, the following technical defects were found in the current cleaning devices: (1) On the one hand, the cleaning device is slidably set on the slide by the sliding mechanism, and the cleaning device and the plate puller share the slide. Therefore, the sliding mechanism and the plate puller need to be set on the slide one after the other. On the other hand, in order to make the water washing pipe of the cleaning device aligned with the current filter plate pulled open by the plate puller, the water washing pipe and the lifting mechanism of the cleaning device need to be extended towards the filter plate using a cantilever structure. That is, the water washing pipe and the lifting mechanism will deviate from the support leg and the sliding mechanism in the direction of travel, resulting in a positional deviation between the center line of gravity of the cleaning device and its centroid line in the direction of travel. This will cause uneven stress on the overall structure of the cleaning device, which will easily generate an off-center load moment, resulting in uneven wear of the front and rear parts of the sliding mechanism in contact with the slide and increased travel resistance. Long-term operation will also cause deformation of the slide and affect the service life of the equipment. (2) The sliding mechanism of the existing cleaning device mostly adopts a wrap-around structure, that is, the slider is completely wrapped on the slide and moves by sliding friction. This structure has high frictional resistance, and the accumulation of material particles between the slider and the slide will accelerate wear. (3) The lifting of the water washing pipe of the existing cleaning device mostly uses multiple guide rods for guidance. Usually, one or more guide rods are set on both sides of the water inlet vertical pipe, which results in a complex overall structure, heavy weight, and high manufacturing cost. At the same time, it increases the load of the lifting drive and reduces the operating efficiency. (4) The locking mechanism between the existing cleaning device and the pull plate mostly adopts a pin or tongue structure. The locking status detection is not accurate enough, which is prone to malfunction and affects the safety and reliability of the equipment operation. Utility Model Content

The plug rod drive component is fixed on the support leg, and the plug rod is installed on the drive end of the plug rod drive component. When the traveling bracket moves to the point where the plug rod and the socket hole are coaxial, the plug rod drive component drives the plug rod to move up and down, so that the plug rod is inserted into or removed from the socket hole.

[0010] Specifically, the support member is formed by vertically connecting a horizontal plate and a vertical plate, with the support leg fixed on the horizontal plate and the support roller and upper limit wheel set on the vertical plate.

[0011] The water washing pipe fitting includes a horizontal pipe and a vertical pipe connected to the top of the horizontal pipe. The horizontal pipe is provided with water spray holes and brushes.

Detailed Implementation

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0017] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1-7 As shown, the filter cloth cleaning device provided by this utility model includes a walking support 100, a water washing pipe 200, a lifting mechanism 300, a sliding support mechanism, and an interlocking mechanism.

[0019] Specifically, the walking support 100 includes a crossbeam 110 and two sets of support legs 120 respectively set at the bottom of both ends of the crossbeam 110. The water washing pipe fitting 200 is installed on the crossbeam 110 through the lifting mechanism 300.

[0020] The sliding support mechanism includes a support member 410 located at the bottom of the support leg 120. Several support rollers 420 are provided on the side of the support member 410, and the axles of the support rollers 420 are parallel to the crossbeam 110.

[0021] The interlocking mechanism is used to lock and unlock the traveling support 100 and the filter press plate puller 630. Specifically, as follows: Figure 2 and Figure 4 , Figure 5 , Figure 7As shown, the interlocking mechanism includes a rod 510, a socket plate 520, and a rod drive component. The socket plate 520 has a socket, and the rod 510 and the socket are axially aligned vertically. The rod drive component is fixed to the bottom of the support leg 120, and the rod 510 is mounted on the drive end of the rod drive component. When the traveling bracket 100 moves to a position where the rod 510 is coaxial with the socket, the rod drive component drives the rod 510 to move up and down, allowing it to insert into or leave the socket. When the rod 510 is inserted into the socket, the traveling bracket 100 and the puller 630 are locked together. As the puller 630 moves, it synchronously moves the traveling bracket 100, sequentially cleaning the filter cloths on each filter plate 620. After the cleaning operation is completed, the rod 510 is removed from the socket, and the traveling bracket 100 and the puller 630 are separated and unlocked, disengaging their linkage.

[0022] like Figure 4 As shown, the filter cloth cleaning device provided by this utility model is adapted for use with conventional filter press equipment. The filter press includes two parallel main beams 610, and filter plates 620 are arranged between the two main beams 610. Handles on both sides of the filter plates 620 are slidably supported on the top of the main beams 610. Each main beam 610 is equipped with a puller 630, an upper chain box 640, and a lower chain box 650. The puller 630 is slidably mounted on the upper chain box 640, and the chain is placed inside the upper chain box 640 and the lower chain box 650. The puller 630 is connected to the chain. When the chain rotates, it can drive the puller 630 to slide along the upper chain box 640. When unloading the cake after filtration, the puller 630 moves back and forth, pulling the filter plates 620 apart in sequence. The connection structure of the puller 630 with the upper chain box 640, the lower chain box 650, and the chain is a conventional configuration on filter presses in this field.

[0023] like Figure 2 As shown, in one specific embodiment, the insert rod drive is a cylinder. The cylinder body is fixed to the bottom of the support leg 120 by a mounting base, and the cylinder rod is connected to the insert rod 510. Typically, the insert rod is hinged to the end of the cylinder rod, which can compensate for alignment errors and absorb small offsets during movement.

[0024] The cylinder is a magnetic switch cylinder 530, which can be further adapted to be a magnetic switch guided cylinder. The piston of the magnetic switch cylinder 530 is equipped with a magnetic ring, and the cylinder body of the magnetic switch cylinder 530 is equipped with two magnetic switches. These switches are used to detect when the cylinder rod is in the extended position to interlock the traveling bracket 100 with the puller 630, and to detect when the cylinder rod is in the retracted position to unlock the traveling bracket 100 from the puller 630. The action detection is accurate and the feedback is timely, ensuring the stable and reliable linkage logic of the equipment.

[0025] like Figure 2As shown, the interlocking mechanism also includes a guide plate 540 disposed on the mounting base. The guide plate 540 has a guide hole, through which the insertion rod 510 passes. The guide hole can constrain the movement of the insertion rod, causing it to move vertically up and down. Two guide plates 540 can be disposed vertically. During interlocking, the insertion plate 520 is inserted between the two guide plates 540.

[0026] like Figure 4 As shown, the filter cloth cleaning device provided by this utility model also includes a positioning block 700 for limiting the stopping position of the traveling support 100. The positioning block 700 is fixed to the end of the main beam 610, corresponding to the stopping position of the traveling support 100. When the traveling support 100 returns to the stopping position, the support member 410 abuts against the end face of the positioning block 700, ensuring accurate stopping position. The positioning block 700 can be made of wear-resistant plastic material, possessing the characteristics of cushioning, noise reduction, scratch prevention, and wear resistance.

[0027] Furthermore, such as Figure 2 and Figure 6 As shown, the side of the support member 410 is also provided with an upper limit wheel 430, which is arranged parallel to the support roller 420 above it. For example, 2-4 support rollers 420 can be provided, and 1-2 upper limit wheels 430 can be provided. The support roller 420 rolls against the top of the lower chain box, effectively reducing wear and resistance, and extending the service life of the equipment.

[0028] Furthermore, a retaining edge 421 is provided around the outer periphery of the end of some of the support rollers 420. The retaining edge 421 can constrain the left and right position of the support rollers 420 on the lower chain box 650, thereby positioning the washing device left and right.

[0029] The support roller 420 bears the entire load of the cleaning device and is generally made of steel. The upper limit wheel 430 rolls against the bottom surface of the chain box 640, cooperating with the support roller 420 to form an upper and lower clamping and limiting structure. The upper limit wheel 430 can be made of polypropylene. When the traveling support 100 travels along the length of the main beam 610, the support roller 420 plays a load-bearing role, and the upper limit wheel 430 plays an anti-tipping role, solving the problems of high wear, easy shaking, and easy tipping of traditional sliding mechanisms, and greatly improving the traveling stability and service life of the cleaning device. Moreover, the sliding support mechanism is adapted to the existing chain box space, making the fit between the cleaning device and the filter press compact.

[0030] The support member 410 is formed by vertically connecting the horizontal plate 411 and the vertical plate 412. The support leg 120 is fixed on the horizontal plate 411, and the support roller 420 and the upper limit wheel 430 are set on the vertical plate 412, so that the overall structure of the sliding support mechanism has strong integrity and high load-bearing stability.

[0031] like Figure 1 and Figure 4 As shown, the water washing fitting 200 includes a horizontal pipe 210 and a vertical pipe 220 connected vertically to the top of the horizontal pipe 210. The horizontal pipe 210 is provided with spray holes and a brush. High-pressure water is introduced through the vertical pipe 220 and sprayed out from the spray holes through the horizontal pipe 210 onto the filter cloth.

[0032] During the up-and-down movement of the lifting mechanism 300 driving the water washing pipe 200, the water flow and the brush work together to thoroughly wash the filter cloth. The lifting mechanism 300 includes a reduction motor 310, a gear 320, and a rack 330. The rack 330 is vertically fixed on the vertical pipe 220. The reduction motor 310 is mounted on the crossbeam 110. The gear 320 is located on the output shaft of the reduction motor 310. The gear 320 meshes with the rack 330, driving the vertical pipe 220 and the horizontal pipe 210 to move up and down stably.

[0033] In one specific embodiment, two sets of water washing pipes are symmetrically equipped on the walking support 100. The tops of the vertical pipes of the two sets of water washing pipes can be connected together by connectors to improve structural stability. This allows for simultaneous brushing of the filter cloth on both sides of the filter plate, and they all share a single geared motor 310. Typically, two bearing seats are installed on the crossbeam 110. A drive shaft is connected to each end of the output end of the geared motor 310. The two shafts pass through the bearing seats and connect to the gear 320. The bearing seats provide radial support to the drive shafts and gear 320, effectively offsetting the transmission load and reducing lifting and lowering vibrations.

[0034] like Figure 1 and Figure 3 As shown, the lifting mechanism 300 also includes a guide sleeve 340 fixed on the crossbeam 110. The vertical tube 220 and the rack 330 pass through the guide sleeve 340, which improves the lifting stability of the vertical tube 220. It integrates water supply, transmission and guiding functions, and does not require an extra guide rod structure. The structure is simplified and lightweight.

[0035] On the other hand, such as Figure 4 As shown, this utility model also provides a filter press, including two parallel main beams 610, each main beam 610 is provided with a puller 630, an upper chain box 640 and a lower chain box 650, the puller 630 is slidably installed on the upper chain box 640, and also includes the filter cloth cleaning device mentioned above.

[0036] The traveling support 100 spans two main beams 610. The crossbeam 110 of the traveling support 100 is perpendicular to the main beam 610 of the filter press. The two sets of support legs 120 are respectively connected to the lower chain box 650 on the corresponding side main beam 610 through a sliding support mechanism. The support roller 420 in the sliding support mechanism rolls and supports the top of the lower chain box 650.

[0037] like Figure 1 and Figure 6As shown, the vertical sides of the upper chain box 640 and the lower chain box 650 are respectively connected to the upper and lower parts of the vertical sides of the main beam 610. The pull plate 630 is slidably mounted on the top of the upper chain box 640. The support roller 420 extends into the area between the upper chain box 640 and the lower chain box 650 and rolls to support the top of the lower chain box 650.

[0038] Furthermore, the insertion plate 520 is mounted on the side of the puller facing the support member 410 via a connector and is located at one end of the puller 630 in the travel direction, while the insertion rod 510 is mounted at the same end of the support member 410 in the travel direction.

[0039] Furthermore, during actual processing, vertical baffles can be set at the edges of the insertion plate and guide plate. As the insertion plate and the insertion rod approach each other to become coaxial, the vertical baffles can provide auxiliary constraints on the approaching position of the insertion plate and the insertion rod, so that the insertion hole and the insertion rod are accurately aligned.

[0040] The filter cloth cleaning device and filter press provided by this utility model have a plate puller and a cleaning device that slide on their respective slides. The center line of gravity and the centroid line of the cleaning device are roughly aligned, eliminating the eccentric load moment of the traditional structure, so that the cleaning device is subjected to uniform force and runs smoothly.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," "linking," and "fixing" should be interpreted broadly.
