Description

Technical Field

[0001] This utility model relates to the field of pressure filtration separation, specifically a pressure filtration separation device for livestock and poultry manure. Background Technology

[0002] A diaphragm filter press is a highly efficient solid-liquid separation device. It is an improvement on the traditional chamber filter press by adding an elastic diaphragm between the filter plates and the filter cloth. This unique design allows for secondary pressing of the filter cake during the filtration process, greatly improving the solid-liquid separation effect.

[0003] Livestock and poultry manure contains a large amount of solid organic matter and moisture, which can cause serious environmental pollution if discharged directly. A diaphragm filter press can remove most of the moisture from livestock and poultry manure, significantly reducing its volume and facilitating subsequent transportation and storage.

[0004] In existing technology, the powder cake formed after dewatering materials by a diaphragm filter press will adhere to the diaphragm, so it needs to be removed manually. During use and observation, it was found that manual removal is usually done from both sides of the diaphragm, using tools such as shovels to remove the powder cake. This desorption method is difficult to remove the powder cake from the diaphragm quickly and consumes a lot of working time.

[0005] Therefore, a livestock and poultry manure pressure filter separation device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A livestock and poultry manure pressure filter separation device of this utility model includes a frame, one side of which is connected to a feed pipe; a first hydraulic cylinder is fixedly connected to the other side of the frame; a push plate is fixedly connected to the output end of the first hydraulic cylinder; multiple partitions are provided on the inner wall of the frame; the partitions near the feed pipe are connected to the feed pipe; the partitions near the push plate are fixedly connected to the push plate; a drain pipe is connected to one side of each partition, and filter membranes are fixedly connected to both sides of each partition; a radial moving module is fixedly connected to the top of the frame; a gantry frame is slidably fitted to the top of the radial moving module; a second hydraulic cylinder is fixedly connected to the top of the gantry frame; a connecting plate is fixedly connected to the output end of the second hydraulic cylinder, and a pair of scrapers are symmetrically fixed to the bottom of the connecting plate; through the combined action of the second hydraulic cylinder and the scrapers, the scrapers can be vertically controlled by the connecting plate, thereby removing the powder cake on both sides of the partition, improving the effect and speed of powder cake desorption by the device.

[0008] Preferably, ear plates are symmetrically fixed to both sides of the partition; a sliding rod is fixed to one side of the ear plate; a sleeve is fixed to the other side of the ear plate; the sliding rod and the sleeve are in sliding fit; through the cooperation of the sleeve and the sliding rod, multiple partitions can be pulled when the push plate is reset, and the sliding relationship between the sleeve and the sliding rod can also provide guidance for the movement between the partitions, reducing the offset that occurs during the movement of the partitions, thereby preventing misalignment of the mold cavities between the partitions.

[0009] Preferably, a positioning rod is fixedly connected to the top of the ear plate; round holes corresponding to the positioning rod are opened on both sides of the connecting plate; by setting the positioning rod, when the second hydraulic cylinder drives the connecting plate to move closer to the partition, the connecting plate will achieve the positioning of the scraper by the engagement between the positioning rod and the round hole, thereby improving the accuracy of the scraper in removing powder from both sides of the partition.

[0010] Preferably, water pipes are symmetrically fixed to both sides of the gantry frame; the inner wall of the water pipes is connected to multiple first nozzles and second nozzles, and the second nozzles are inclined; when the scraper has finished removing the powder cake from the surface of the partition and is retracted by the second hydraulic cylinder, water can be sprayed from the first nozzles and second nozzles by connecting the water pipes to the water pump. The water sprayed from the first nozzles is directed towards the surface of the scraper to rinse the material remaining on the outer wall of the scraper. At the same time, the inclined second nozzles can also clean the surface of the partition when the scraper moves to a certain stroke.

[0011] Preferably, a baffle is fixed to one side of the water pipe; the baffle has an arc-shaped structure; by setting the baffle, when the water jet from the first nozzle sprays onto the scraper surface, it will splash due to the impact, and the baffle can block the splashing water jet to reduce the contamination of these water droplets on the surrounding components.

[0012] Preferably, the outer wall of the slide rod is light-colored; by setting the slide rod to a light color, when the push plate presses multiple partitions together, the degree of closeness between the partitions can be judged by observing the exposed part of the slide rod, and thus the pressing force of the push plate can be appropriately controlled.

[0013] The advantages of this utility model are: 1. The livestock and poultry manure pressure filter separation device of this utility model, through the cooperation of the second hydraulic cylinder and the scraper, can vertically control the scraper through the connecting plate, thereby removing the powder cake on both sides of the partition, improving the effect and speed of powder cake desorption of the device.

[0014] 2. The livestock and poultry manure pressure filter separation device of this utility model, through the cooperation of the sleeve and the slide rod, allows multiple partitions to be pulled when the push plate is reset. At the same time, the sliding relationship between the sleeve and the slide rod can also provide guidance for the movement between the partitions, reducing the offset that occurs during the movement of the partitions, thereby preventing misalignment of the mold cavities between the partitions.

[0018] 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 scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figures 1 to 5As shown in the figure, a livestock and poultry manure pressure filtration and separation device according to an embodiment of the present invention includes a frame 1, one side of which is connected to a feed pipe 12; a first hydraulic cylinder 13 is fixedly connected to the other side of the frame 1; a push plate 14 is fixedly connected to the output end of the first hydraulic cylinder 13; a plurality of partitions 15 are provided on the inner wall of the frame 1; the partitions 15 near the feed pipe 12 are connected to the feed pipe 12; the partitions 15 near the push plate 14 are fixedly connected to the push plate 14; a drain pipe 17 is connected to one side of the partition 15, and filter membranes 16 are fixedly connected to both sides of the partition 15; the top of the frame 1 is fixedly connected to the filter membrane 16. A radial moving module 18 is connected; a gantry frame 19 is slidably fitted on the top of the radial moving module 18; a second hydraulic cylinder 110 is fixedly connected to the top of the gantry frame 19; a connecting plate 111 is fixedly connected to the output end of the second hydraulic cylinder 110, and a pair of scrapers 112 are symmetrically fixedly connected to the bottom of the connecting plate 111; during operation, the first hydraulic cylinder 13 can be activated to squeeze multiple partitions 15 through the push plate 14, so that the partitions 15 are close to each other, and then the material can be injected into the partitions 15 through the feed pipe 12 by the conveying pump. The material will accumulate between the filter membranes 16 through the cavity between the partitions 15. The pressure applied by the first hydraulic cylinder 13 and the conveying pump allows the moisture in the material to pass through the filter membrane 16 and be discharged into the water tank via the drain pipe 17. This is the working principle of the diaphragm filter press in the prior art, so the specific structure and principle involved will not be described in detail. After dewatering, the first hydraulic cylinder 13 can be activated to reset the diaphragm 15 via the push plate 14. After resetting, the gantry frame 19 can be controlled to slide along the radial moving module 18. The sliding control method can be electric control, i.e., linear motor or linear slide table, which will not be described in detail here. The gantry frame 19 is controlled to be at the top of the diaphragm 15. The second hydraulic cylinder 110 can then be activated to push the connecting plate 111 closer to the partition 15. The connecting plate 111, along with the scraper 112, will remove the powder cakes attached to both sides of the partition 15. The removed powder cakes can fall onto the conveyor and be transported to the next processing area. It is worth mentioning that the powder cakes at the end of the partition 15 can be removed manually due to obstruction by the pipe. Through the combined action of the second hydraulic cylinder 110 and the scraper 112, the connecting plate 111 can be used to vertically control the scraper 112, thereby removing the powder cakes on both sides of the partition 15 and improving the effect and speed of powder cake removal by the device.

[0021] Please see Figure 2 and Figure 3As shown, ear plates 2 are symmetrically fixed to both sides of the partition 15; a sliding rod 23 is fixed to one side of the ear plate 2; a sleeve 22 is fixed to the other side of the ear plate 2; the sliding rod 23 and the sleeve 22 are in sliding fit; when the first hydraulic cylinder 13 pulls the multiple partitions 15, the push plate 14 applies a pulling force to the adjacent partitions 15, and the partition 15 will slide along the sleeve 22 of the adjacent partition 15 with the sliding rod 23 until the sliding rod 23 and the inner wall of the sleeve 22 are in contact. At this time, the two partitions 15 will be in a relatively stationary state under the contact action of the sliding rod 23 and the inner wall of the sleeve 22, that is, the partition 15 can be moved through. The sleeve 22 and the slide rod 23 pull another partition 15. Repeat the above steps until the push plate 14 can pull the remaining partitions 15. It is worth mentioning that if the partition 15 near the feed pipe 12 is a sliding design, it should be connected to the feed pipe 12 through a flexible hose. Through the cooperation of the sleeve 22 and the slide rod 23, the push plate 14 can pull multiple partitions 15 when it resets. At the same time, the sliding relationship between the sleeve 22 and the slide rod 23 can also provide guidance for the movement between partitions 15, reducing the offset that occurs during the movement of partitions 15, and thus preventing misalignment of the mold cavities between partitions 15.

[0022] Please see Figures 1 to 4 As shown, a positioning rod 3 is fixedly connected to the top of the ear plate 2; the connecting plate 111 has round holes on both sides corresponding to the positioning rod 3; by setting the positioning rod 3, when the second hydraulic cylinder 110 drives the connecting plate 111 to move closer to the partition plate 15, the connecting plate 111 will achieve the positioning of the scraper 112 by the engagement between the positioning rod 3 and the round hole, thereby improving the accuracy of the scraper 112 in removing powder from both sides of the partition plate 15.

[0023] Please see Figure 4 and Figure 5 As shown, water pipes 4 are symmetrically fixed to both sides of the gantry frame 19; the inner wall of the water pipes 4 is connected to multiple first nozzles 42 and second nozzles 43, and the second nozzles 43 are inclined; when the scraper 112 has finished scraping off the powder cake on the surface of the partition 15 and is retracted by the second hydraulic cylinder 110, the water pipes 4 can be connected to the water pump so that water can be sprayed from the first nozzles 42 and the second nozzles 43. The water sprayed from the first nozzles 42 is directed towards the surface of the scraper 112 to wash the material remaining on the outer wall of the scraper 112. At the same time, the inclined second nozzles 43 can also clean the surface of the partition 15 when the scraper 112 moves to a certain stroke.

[0024] Please see Figure 5 As shown, a baffle 5 is fixed to one side of the water pipe 4; the baffle 5 has an arc-shaped structure; by setting the baffle 5, when the water jet from the first nozzle 42 sprays onto the surface of the scraper 112, it will splash due to the impact. The baffle 5 can block the splashing water jet to reduce the contamination of these water droplets on the surrounding components.

[0025] Please see Figure 2 and Figure 3 As shown, the outer wall of the slide rod 23 is set in a light color; by setting the slide rod 23 in a light color, when the push plate 14 presses the multiple partitions 15 close together, the degree of closeness between the partitions 15 can be judged by observing the exposed part of the slide rod 23, and the pressing force of the push plate 14 can be appropriately controlled.

[0026] Working principle: By activating the first hydraulic cylinder 13, multiple partitions 15 are squeezed together by the push plate 14, causing the partitions 15 to come into close contact with each other. Then, material is injected into the partitions 15 through the feed pipe 12 via the delivery pump. The material accumulates between the filter membranes 16 through the cavities between the partitions 15. Due to the pressure applied by the first hydraulic cylinder 13 and the delivery pump, the moisture in the material is discharged into the water tank through the drain pipe 17 via the filter membrane 16. This is the working principle of the diaphragm filter press in the prior art; therefore, the specific structure and principle involved will not be elaborated further. After dewatering, the partitions 15 can be reset by activating the first hydraulic cylinder 13 via the push plate 14. After reset, the gantry frame 19 can be controlled to move radially. Module 18 slides, and the sliding control method can be electric control, i.e., linear motor or linear slide table, which will not be elaborated here. The gantry 19 is positioned at the top of partition 15, and then the second hydraulic cylinder 110 can be activated to push the connecting plate 111 closer to partition 15. The connecting plate 111, along with the scraper 112, removes the powder cake attached to both sides of partition 15. The removed powder cake falls onto the conveyor for transport to the next processing area. It is worth mentioning that the powder cake at the end of partition 15 can be removed manually due to pipe obstruction. When multiple partitions 15 are pulled by the first hydraulic cylinder 13, the pusher 14 applies a pulling force to adjacent partitions 15, and the partition 15, along with the slide rod 23, moves along the sleeve of the adjacent partition 15. The slide bar 23 slides within the tube 22 until it contacts the inner wall of the sleeve 22. At this point, the two partitions 15 are relatively stationary due to the contact between the slide bar 23 and the inner wall of the sleeve 22. That is, partition 15 can pull the other partition 15 through the sleeve 22 and the slide bar 23. Repeat the above steps until the push plate 14 can pull the remaining partitions 15. It is worth mentioning that if the partition 15 near the feed pipe 12 is a sliding design, it should be connected to the feed pipe 12 through a flexible hose. By setting the positioning rod 3, when the second hydraulic cylinder 110 drives the connecting plate 111 to move closer to the partition 15, the connecting plate 111 will achieve the positioning of the scraper 112 by the engagement between the positioning rod 3 and the round hole, thereby improving the positioning of the scraper 112 on the partition. The accuracy of the position when removing powder from both sides of the plate 15; when the scraper 112 has finished removing the powder from the surface of the partition 15 and is retracted by the second hydraulic cylinder 110, water can be sprayed from the first nozzle 42 and the second nozzle 43 by connecting the water pipe 4 to the water pump. The water sprayed from the first nozzle 42 is directed towards the surface of the scraper 112 to wash away the material remaining on the outer wall of the scraper 112. At the same time, the inclined second nozzle 43 can also clean the surface of the partition 15 when the scraper 112 moves to a certain stroke. By setting the baffle 5, when the water sprayed from the first nozzle 42 sprays onto the surface of the scraper 112, it will splash due to the impact. The baffle 5 can block the splashing water to reduce the contamination of the surrounding parts by these water droplets.By setting the slide bar 23 to a bright color, when the push plate 14 presses the multiple partitions 15 closer together, the degree of closeness between the partitions 15 can be judged by observing the exposed part of the slide bar 23, thereby allowing for appropriate control of the pressing force of the push plate 14.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
