Description

Technical Field

[0001] This utility model relates to the field of filter plate positioning technology for filter presses, specifically a filter plate positioning mechanism for filter presses. Background Technology

[0002] As an important piece of equipment for solid-liquid separation, the filter press is widely used in industries such as chemical and food due to its efficient and stable separation performance. During the operation of the filter press, the filter plate is the key factor to ensure the normal operation and filtration effect of the filter press. However, the current filter plate unloading process has significant drawbacks, which has become a bottleneck restricting the overall efficiency improvement of the filter press. The plate-by-plate separation method will cause a lot of time to be wasted on the movement and adjustment of the filter plate, which cannot meet the growing industrial production needs. Therefore, a filter plate positioning mechanism for filter presses has emerged.

[0003] The original filter plate positioning device for the filter press has the following problems: First, when adjusting the position of the filter plates during unloading, only one filter plate can be moved. Each adjustment requires a complete process including drive calibration, which causes the auxiliary operation time to increase linearly. A large amount of time is spent on moving the filter plates during unloading, reducing the amount of filter plates processed per unit time. The cumulative adjustment time of multiple filter plates will significantly lengthen the entire filter press cycle, seriously affecting the production rhythm and failing to meet the needs of efficient continuous production, resulting in a significant decrease in equipment production efficiency. Second, during long-term operation of the equipment, the lack of lubrication between the track and the drive components will generate large friction, which will significantly increase the resistance of the drive device to push the filter plates. At the same time, frequent friction will aggravate the wear of the track and drive components, shorten the service life of key components of the drive device, and even cause the drive device to jam and malfunction, affecting the normal and stable operation of the filter press and reducing production continuity.

[0004] To address these issues, we provide a filter plate positioning mechanism for a filter press. Utility Model Content

[0005] The purpose of this utility model is to provide a filter plate positioning mechanism for a filter press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter plate positioning mechanism for a filter press, comprising a base and a constitutive mechanism, wherein the constitutive mechanism is provided above the base, a filter plate group driving mechanism is installed inside the base, and a lubrication assembly is provided inside the base.

[0007] Preferably, the structure includes two filter plate moving tracks fixedly connected to the inner side of the base, a hydraulic device is installed on the base, a connecting pipe is fixedly connected to one side of the hydraulic device, a pressure plate is fixedly connected to one side of the connecting pipe, and filter plates are slidably connected on the filter plate moving tracks.

[0008] Preferably, the filter plate group driving mechanism includes two guide rail grooves fixedly connected to the inner side of the base. The guide rail grooves are slidably connected to the base plate through rollers, so that the base plate can move in the direction defined by the guide rail grooves. A hydraulic press is fixedly connected to the upper end of the base plate, and a hydraulic rod is provided on one side of the hydraulic press.

[0009] Preferably, a hydraulic cylinder housing is fixedly connected to one side of the hydraulic rod, a push plate one is fixedly connected to one side of the hydraulic cylinder housing, a push plate two is fixedly connected to one side of the hydraulic cylinder housing, and a push plate three is fixedly connected to one side of the hydraulic cylinder housing. The push plates one, two, and three are equidistant and arranged on the hydraulic cylinder housing at the same horizontal line.

[0010] Preferably, the lubrication assembly includes an oil tank fixedly connected to one side of the base plate, a pressure pump fixedly connected above the oil tank, and a nozzle fixedly connected to one side of the oil tank, with the nozzle and the roller at the same horizontal level.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model constructs a filter plate group driving mechanism by adding a hydraulic cylinder housing and push plates. Three push plates are inserted into the gaps between the filter plates to push the filter plates to a predetermined distance to achieve separation. This eliminates the previous mode of moving filter plates one by one by mechanical devices, saving time. In the past, when moving filter plates one by one by mechanical devices, the movement of each filter plate required a series of processes such as starting and moving, and the time cost increased linearly. However, this mechanism can drive multiple filter plates to move synchronously, which improves the working efficiency of the filter press and effectively meets the demand for high efficiency in continuous production.

[0013] 2. This utility model incorporates a lubrication assembly consisting of a pressure pump and an oil tank. The pressure pump provides power to spray lubricating oil from the oil tank through the nozzle, lubricating the repeatedly moving rollers. This significantly improves the operation of the filter plate pushing device, greatly reduces the friction between the two, and makes the drive device push the filter plate more smoothly and efficiently, improving equipment operating efficiency, effectively reducing wear on the track and drive components, reducing maintenance frequency and costs, and ensuring the long-term stable operation of the filter press.

[0024] 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.

[0025] Please see Figure 1-6 The present invention provides an embodiment of a filter plate positioning mechanism for a filter press, comprising a base 1 and a constitutive mechanism 2. The constitutive mechanism 2 is disposed above the base 1, a filter plate group driving mechanism 3 is installed inside the base 1, and a lubrication assembly 4 is disposed inside the base 1.

[0026] Furthermore, the constitutive mechanism 2 includes two filter plate moving tracks 201 fixedly connected to the inner side of the base 1. A hydraulic device 202 is installed on the base 1. A connecting pipe 203 is fixedly connected to one side of the hydraulic device 202, and a pressure plate 204 is fixedly connected to one side of the connecting pipe 203. Filter plates 205 are slidably connected on the filter plate moving tracks 201. The hydraulic device 202 generates force that is transmitted to the connecting pipe 203 and the pressure plate 204 respectively. The pressure plate 204 moves on the filter plate moving tracks 201. Under the force of the hydraulic device 202, several filter plates 205 on the filter plate moving tracks 201 are squeezed together to form a filter structure with filtration function, thereby realizing the filtration operation of the fluid medium.

[0027] Furthermore, the filter plate group drive mechanism 3 includes two guide rail grooves 301 fixedly connected to the inner side of the base 1. The guide rail grooves 301 are slidably connected to the base plate 302 through rollers 303, which allows the base plate 302 to move in the direction defined by the guide rail grooves 301. A hydraulic press 304 is fixedly connected to the upper end of the base plate 302. A hydraulic rod 305 is provided on one side of the hydraulic press 304. When the machine needs to separate several filter plates 205 to unload the mud after filtration, the hydraulic press 304 outputs power to push out the hydraulic rod 305 and the hydraulic cylinder housing 306 connected to it, allowing the filter plate group drive mechanism 3 to slide left and right. If it is not pushed out, the filter plate group drive mechanism 3 will be restricted from sliding left and right due to the obstruction of the filter plates 205. After pushing a group of filter plates 205 to complete the movement, the filter plate group drive mechanism 3 returns to the starting position in the pushed state and pushes the filter plates 205 in the unpushed state to ensure that the separation operation of the filter plates 205 can be carried out smoothly and continuously.

[0028] Furthermore, a hydraulic cylinder housing 306 is fixedly connected to one side of the hydraulic rod 305. A push plate 307, a push plate 308, and a push plate 309 are fixedly connected to one side of the hydraulic cylinder housing 306. The push plates 307, 308, and 309 are equidistant and on the same horizontal line on the hydraulic cylinder housing 306. During sludge unloading, given the equal spacing between the filter plates 205, the hydraulic cylinder housing 306, in its extended state, is driven... Push plates 307, 308, and 309 are inserted to match the gap between the filter plates 205. After adjustment, the hydraulic press 304 drives the filter plate group drive mechanism 3 from the push-out state to the non-push-out state. At this time, the three push plates are inserted into the gap between the filter plates 205 and push the filter plates 205 to a predetermined distance to achieve separation. After separation, the mechanism returns to the push-out state, and the filter plate group drive mechanism 3 retracts to the position of the unseparated filter plates 205. The hydraulic cylinder housing 306 readjusts the push plate spacing and repeats the above actions until all filter plates 205 are separated.

[0029] Furthermore, the lubrication assembly 4 includes an oil tank 401 fixedly connected to one side of the base plate 302, a pressure pump 402 fixedly connected above the oil tank 401, and a nozzle 403 fixedly connected to one side of the oil tank 401. The nozzle 403 and the roller 303 are at the same horizontal line. The pressure pump 402 provides power to spray the lubricating oil in the oil tank 401 from the nozzle 403 to lubricate the repeatedly moving roller 303 and extend its service life.

[0030] Working principle: After the machine finishes filtration, several filter plates 205 need to be separated to unload the sludge. At this time, the hydraulic press 304 outputs power to push out the hydraulic rod 305 and the hydraulic cylinder housing 306 connected to it, allowing the filter plate group drive mechanism 3 to slide left and right. If it is not pushed out, the filter plate group drive mechanism 3 will be restricted from sliding left and right due to the obstruction of the filter plates 205. After pushing a group of filter plates 205 to complete the movement, the filter plate group drive mechanism 3 returns to the starting position in the pushed state. In the non-pushed state, it pushes the filter plates 205 to ensure that the separation operation of the filter plates 205 can be carried out smoothly and continuously. Since the spacing between the filter plates 205 is equal, the hydraulic cylinder housing 306 in the pushed state drives the push plate 1 307, push plate 2 308 and push plate 309, so that the spacing between the three is equal to that between the filter plates 205. After the gap is fitted and inserted, the hydraulic press 304 drives the filter plate group drive mechanism 3 from the push-out state to the non-pull-out state. At this time, the three push plates are inserted into the gap of the filter plate 205 and push the filter plate 205 to the predetermined distance to achieve separation. After separation, the mechanism returns to the push-out state, and the filter plate group drive mechanism 3 retracts to the position of the unseparated filter plate 205. The hydraulic cylinder housing 306 readjusts the push plate spacing and repeats the above actions until all filter plates 205 are separated so that impurities between the filter plates 205 can be removed. Since the roller 303 of the filter plate group drive mechanism 3 needs to slide repeatedly in the guide rail groove 301, in order to extend its service life and ensure the smooth operation of the filter plate group drive mechanism 3, the pressure pump 402 provides power to spray the lubricating oil in the oil tank 401 from the nozzle 403 for regular maintenance.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
