Description

Technical Field

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

[0002] Filter presses are core equipment in the solid-liquid separation industry, widely used in chemical, mining, and environmental protection fields. Their core working principle is to achieve solid-liquid separation through the squeezing action of filter plates and the filtration action of filter cloth. During continuous operation, a large amount of filter residue easily adheres to the surface of the filter cloth. If the filter cloth is not cleaned in time, it will directly lead to a significant decrease in the filtration efficiency of the filter press, and may even cause filter cloth blockage and filter plate damage. Therefore, a cleaning mechanism and a rapping mechanism are required to clean the filter cloth. Currently, the cleaning and rapping mechanisms of filter presses on the market are independent devices, increasing equipment costs and installation space. They also require separate operation, resulting in a cumbersome process and poor coordination. Furthermore, existing rapping mechanisms mostly rappe a single filter plate at a time, and cleaning mechanisms mostly clean each filter plate individually, failing to achieve simultaneous operation of multiple filter plates, leading to long overall operation times and difficulty in meeting the demands of high-efficiency production. Moreover, the currently used cleaning mechanisms are relatively tall, requiring significant plant height and occupying a large space. Utility Model Content

[0018] 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.

[0019] 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.

[0020] like Figures 1-14 As shown, the filter cloth cleaning and vibration device provided by this utility model includes a mounting frame 100, a traveling trolley, a cleaning mechanism and a vibration mechanism, both of which are mounted on the traveling trolley.

[0021] refer to Figure 1 The mounting bracket 100 includes two parallel support beams 110 and two support legs 120, with the two ends of the support beams 110 along their length fixed to the two support legs 120 respectively.

[0022] refer to Figure 2 The vehicle includes a frame 210 and a drive mechanism. The frame 210 is movably mounted on the mounting frame 100 along the length of the support beam 110, and the drive mechanism is used to drive the frame 210 to move on the mounting frame 100. Figure 1 The x-direction is the length direction of the supporting beam.

[0023] refer to Figure 3 The cleaning mechanism includes several water distribution pipes 310, the length of which is perpendicular to the length of the support beam 110. Each water distribution pipe 310 has a set of nozzles 320 installed on its left and right sides along its length. The nozzles 320 spray towards the lower left and lower right of the water distribution pipe 310, respectively. The nozzles 320 are used to spray cleaning media onto the filter cloth. Preferably, the nozzles 320 on the left and right sides of each water distribution pipe 310 are arranged alternately.

[0024] Furthermore, the cleaning mechanism also includes two parallel main water pipes 330, and each branch water pipe 310 is arranged between the two main water pipes 330. Both ends of each branch water pipe 310 are connected to the two main water pipes 330 respectively, forming an overall frame structure. The overall frame structure is connected to the vehicle frame through multiple hangers.

[0025] refer to Figure 1 , Figures 4-6The vibration mechanism includes several vibration units 410 respectively installed on the left and right sides of the frame 210 in the direction of travel. Each vibration unit 410 includes several vibration cylinders 411. The cylinder rod of the vibration cylinder 411 extends downward and a vibration rod 412 is provided at the lower end of the cylinder rod. In a preferred embodiment, each vibration unit 410 includes two vibration cylinders 411. The cylinder rods of the two vibration cylinders 411 are connected to the same vibration rod 412. One vibration rod 412 can simultaneously strike multiple adjacent hanging rods 810, thus saving the number of vibration cylinders 411.

[0026] During operation, the traveling vehicle moves back and forth on the mounting frame 100, driving the cleaning mechanism and the rapping mechanism to move above the filter plate, cleaning the filter plate and rapping to unload the filter cake.

[0027] like Figure 2 As shown, in a preferred embodiment, the left and right sides of the frame 210 are respectively provided with limiting wheels 211. The axles of the limiting wheels 211 are vertically arranged, and the wheel surface of each limiting wheel 211 on the left and right sides makes rolling contact with the vertical beam surface of the corresponding side support beam 110. When the frame 210 is running, the limiting wheels 211 on both sides move along the support beam 110, so that the frame 210 runs smoothly.

[0028] Furthermore, the filter cloth cleaning and vibration device provided by this utility model also includes a plate-picking triggering mechanism. The plate-picking triggering mechanism includes a plate-picking sensor 510 and a plate-picking trigger 520. The plate-picking sensor 510 is disposed on the left or right side of the frame 210, and the plate-picking trigger 520 is disposed on the filter plate 730. During the movement of the frame 210, when the plate-picking sensor 510 detects the plate-picking trigger 520 on the filter plate 730, it will send a command to the control system of the filter press to control the traveling carriage to stop moving and continue to perform the plate-pulling operation.

[0029] Specifically, such as Figure 7 As shown, the filter cloth cleaning and vibration device provided by this utility model also includes a plate washing triggering mechanism. The plate washing triggering mechanism includes a plate washing sensor 610 and a plate washing trigger 620. The plate washing sensor 610 is disposed on the left or right side of the frame 210, and the plate washing trigger 620 is disposed on the filter plate 730. During the movement of the frame 210, when the plate washing sensor 610 senses the proximity of the plate washing trigger 620 on the filter plate 730, it will send a command to the control system of the filter press to execute the vibration and cleaning program.

[0030] It should be noted that, as Figure 8As shown, the filter cloth cleaning and vibration device provided by this utility model is applicable to ordinary filter presses disclosed before the application date. In addition to components such as the main beam 710, thrust plate 720, filter plates 730, pressing plate 740, cylinder seat 750, and plate puller 760, ordinary filter presses are also equipped with a currently disclosed filter plate grouping and opening mechanism, as well as a control system for automatic operation. Furthermore, all filter plates are divided into several filter plate groups, and the filter plates 730 constituting each filter plate group are sequentially connected together by a hinge mechanism 770. For example, the invention application with publication number CN111437641A, entitled "A Filter Cloth Cleaning System for a Filter Press," discloses dividing all filter plates into several filter plate groups, connecting the filter plates within each filter plate group using a spacing maintaining device, and using a plate pulling trolley to pull the first filter plate in the filter plate group to sequentially open the filter plates within the group. For example, six filter plates 730 can be connected into a filter plate group by a hinge mechanism 770. The puller 760 can pull open the six filter plates 730 by moving once.

[0031] Based on the grouped pull plate, such as Figures 9-11 As shown, in each filter plate assembly, the plate-removing trigger 520 and the plate-washing trigger 620 are respectively disposed on the two outermost filter plates of each filter plate assembly. For example, during operation, the traveling vehicle moves from... Figure 9 The filter moves from right to left. The plate washing sensor 610 and the plate picking trigger 520 are located on the left side of the traveling vehicle, with the plate washing sensor 610 located to the left of the plate picking sensor. The plate picking trigger 520 and the plate washing trigger 620 are respectively located on the leftmost and rightmost filter plates of each filter plate group. After the filter pressing is completed, the operation is carried out according to the following steps: S1. As Figure 9 As shown in the diagram, the plate puller pulls the Nth filter plate group to the right to the first position, so that the filter plates in the first filter plate group are spaced apart; then, the traveling vehicle moves from the right side of the filter plate group to the left. S2. For example Figure 10 As shown, when the plate-picking sensor 510 approaches the left side of the Nth filter plate group and detects the plate-picking trigger 520 on its leftmost filter plate, the traveling vehicle stops. S3. For example Figure 11 As shown, the plate puller operates, pulling the N+1th filter plate group to the right. When the washing plate sensor 610 detects the washing plate trigger 620 on the right side of the N+1th filter plate group, the plate puller stops working, and the control system receives the instruction to execute the vibration and water washing program.

[0032] In this vibration and cleaning operation, the vibration and cleaning range includes the corresponding filter plates in the Nth filter plate group and the N+1th filter plate group. By repeating the above S1-S3, vibration and cleaning operations can be performed on all filter plate groups.

[0033] In actual production, the installation position of the washing trigger 620 is adjusted according to the distribution range of the rapping rod 412 and the water distribution pipe 310 to ensure that the working range of the rapping mechanism and the washing mechanism can cover the corresponding number of filter plates.

[0034] like Figure 2 As shown, in a preferred embodiment, the drive mechanism includes a rack 221, a gear 222, a gear shaft 223, and a motor 224. Specifically, the gear shaft 223 is mounted on the frame, and its length direction is perpendicular to the length direction of the support beam 110. Gears 222 are mounted on both ends of the gear shaft 223. The rack 221 is mounted on the support beam 110, and the gears 222 mesh with the rack 221. The output shaft of the motor 224 is driven to the gear shaft 223 via a gearbox 222. When the motor 224 drives the gear shaft 223 to rotate via the gearbox 222, the gear shaft 223 drives the gear 222 to rotate, causing the gear 222 to move precisely along the rack 221, thereby accurately controlling the movement position of the frame 210.

[0035] Typically, the frame 210 has several wheels 212 on its left and right sides in the direction of travel, for example, two wheels 212 on each side, and the wheel surfaces of the wheels 212 are supported on the corresponding support beams 110. Preferably, two wheels 212 are respectively mounted on both ends of the gear shaft 223.

[0036] This utility model also provides a filter press, including the aforementioned filter cloth cleaning and vibration device.

[0037] Specifically, such as Figure 8 As shown, the filter press includes two parallel main beams 710. Between the two main beams 710, along the length of the main beams 710, a thrust plate 720, a filter plate 730, a pressing plate 740, and a cylinder seat 750 are arranged sequentially. The thrust plate 720 and the cylinder seat 750 are fixedly connected to the main beams 710. The filter plate 730 and the pressing plate 740 can move along the length of the main beams 710. Each filter plate 730 has a filter cloth 780 attached to both sides. Each filter plate 730 has a handle 790 on both sides, and the handles 790 on both sides are slidably supported on the two main beams 710.

[0038] The support beam 110 is mounted above the filter plate 730, and the length direction of the support beam 110 is parallel to the length direction of the main beam 710. The two support legs 120 are fixed on the thrust plate 720 and the cylinder seat 750, respectively.

[0039] like Figure 12As shown, a hanging rod 810 is provided directly above the filter plate 730. The length direction of the hanging rod 810 is perpendicular to the length direction of the main beam 710. The two ends of the hanging rod 810 are mounted on the filter plate 730 by vertically telescopic springs 820. The upper edges of the two filter cloths 780 on each filter plate 730 are connected to the hanging rod 810, and the lower part of the filter cloths 780 hangs down and covers the plate surface of the filter plate 730. The portions of the two filter cloths 780 located between the hanging rod 810 and the top of the filter plate 730 are inclined to the lower left and lower right of the length direction of the hanging rod 810, respectively.

[0040] like Figure 13 As shown, during cleaning, two sets of nozzles 320 on the same water distribution pipe 310 spray water obliquely downwards onto the upper inclined surface of the filter cloth 780 on two adjacent filter plates 730, allowing the water to flow downwards along the surface of the filter cloth 780 by its own weight. The rapping cylinder 411 is used to intermittently rappel downwards on the hanging rod 810, which causes the filter cloth 780 to shake up and down, removing the filter cake remaining on the filter cloth 780.

[0041] Typically, to guide the up-and-down movement of the hanging rod 810, through holes are provided at both ends of the hanging rod 810. A fixing seat is provided on each side of the filter plate 730, located above the handle 790. A guide rod is fixed to each fixing seat, with its upper part freely passing through the through holes at both ends of the hanging rod 810. An anti-detachment part is provided at the top of the guide rod to prevent it from dislodging from the through holes. A spring 820 is sleeved on the guide rod, with its upper and lower ends abutting against the hanging rod 810 and the fixing seat, respectively. Initially, the spring 820 is in a compressed state.

[0042] It should be noted that the filter cloth 780 hanging method used in this utility model is a structure that has been disclosed in the prior art. For example, the specific filter cloth hanging structure is disclosed in the utility model patent with announcement number CN219072194U and titled "A Filter Cloth Hanging and Vibrating Device for a Filter Press".

[0043] like Figure 14 As shown, during operation, the cylinder rod of the vibrating cylinder 411 reciprocates, driving the vibrating rod 412 to strike the hanging rod 810, causing the hanging rod 810 to slide up and down along the guide rod and compress or to reset the spring 820, thereby causing the filter cloth 780 to shake up and down, shaking off the filter cake remaining on the filter cloth 780.

[0044] Typically, the plate-removing sensor 510 and the plate-washing sensor 610 are proximity switches, the plate-removing trigger 520 is installed on the handle of the filter plate, and the plate-washing trigger 620 is installed on the fixed base.
