Description
Technical Field
[0001] This utility model relates to the field of scraper technology, and in particular to a belt scraper for a plate and frame filter press. Background Technology
[0002] Plate and frame filters, as a common solid-liquid separation device, are used in the chemical and environmental protection fields. During operation, sludge inevitably adheres to the surface of the belt. If not cleaned in time, it will affect the filtration efficiency and normal operation of the equipment. The belt scraper plays a crucial role at this time. By making close contact with the belt surface, it uses its own structure to scrape off the sludge on the belt, thereby ensuring that the belt is always in good working condition. This helps the plate and frame filter to efficiently complete the solid-liquid separation operation and provides a stable and reliable guarantee for subsequent production processes.
[0003] A search revealed Chinese Patent Publication No. CN219488707U, which discloses a belt-driven scraper, relating to the field of scraper technology. This utility model includes a stroke guide frame, one end of which is rotatably connected to a handwheel shaft. A threaded rod is rotatably connected to the inner side of the stroke guide frame, one end of which is fixedly connected to the handwheel shaft. Guide grooves are provided on both sides inside the stroke guide frame. A linkage adjustment scraper structure is threadedly connected to the outer side of the threaded rod. One end of the linkage adjustment scraper structure is fixedly connected to a collection and discharge structure by screws. This utility model... The design of the guiding and adjusting structure in conjunction with the scraper structure makes it easier to better guide the distance between the scraper and the belt, improving the accuracy of contact with the belt. The design of the collection and discharge structure facilitates the collection and timely discharge of scraped mud, avoiding the lack of collection after the mud is scraped off, which would affect the use effect. However, in actual use, the mud and impurities scraped off the belt have strong adhesion, which causes the mud to stick to the top of the scraper, resulting in blockage of the scraper and poor cleaning effect. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a belt scraper for a plate and frame filter press, which aims to improve the problem in the prior art where sticky mud adheres to the top of the scraper, causing the scraper to become clogged.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a belt scraper for a plate and frame filter press, comprising two support rods, with scrapers rotatably connected to adjacent sides of the top ends of the two support rods, and compression springs rotatably connected to the left and right sides of the outer walls of the scrapers, the bottom ends of the compression springs being rotatably connected to the bottom ends of the corresponding support rods, a striking mechanism being provided on the rear side of the support rods, and a quick-installation mechanism being provided at the bottom end of the support rods; The striking mechanism includes a rotating shaft, the left and right ends of which are rotatably connected to the middle of adjacent sides of the two support rods. Multiple cams are fixedly connected to the middle of the outer wall of the rotating shaft. Rotary plates are rotatably connected to the left and right sides of the outer wall of the rotating shaft. A limiting rod is fixedly connected to the rear top of each support rod. A tension spring is provided on the outer wall of the limiting rod. The top of the tension spring engages with the outer wall of the corresponding limiting rod, and the bottom of the tension spring engages with the middle of the outer wall of the corresponding rotating plate. A rotating column is rotatably connected to the rear of adjacent sides of the two rotating plates. Rollers are rotatably connected to the left and right sides of the middle of the outer wall of the rotating column. A transmission assembly is provided on the right side of the outer wall of the rotating column.
[0006] Through the above technical solution: the support rod provides stable support for the overall structure, and the contraction spring keeps the scraper 4 in close contact with the belt surface. When the conveyor belt starts to rotate, the roller is driven to rotate synchronously under the action of friction because it contacts the bottom of the conveyor belt. This causes the rotating column to rotate accordingly, and multiple cams in the middle of the rotating shaft also rotate synchronously. Under the tension of the tension spring, the rotating plate always maintains the tendency to rotate upward, ensuring that the roller is firmly in contact with the bottom of the conveyor belt and ensuring stable power transmission. At the same time, through the transmission component, the power is transmitted to the top of the rotating shaft. During the rotation of the cam, it will periodically push the rotating plate, and with the tension of the tension spring, the rotating plate will oscillate back and forth, driving the rotating column and roller to indirectly cause the cam to continuously strike the bottom side of the scraper. When there is mud stuck on the scraper, it is easier to fall off under the action of vibration, improving the mud scraping effect.
[0007] As a further description of the above technical solution: The quick installation mechanism includes two limiting grooves. The outer walls of the two limiting grooves are formed at the bottom of the support rod. Sliding blocks are slidably connected to the inner walls of the limiting grooves. Limiting plates are fixedly connected to adjacent sides of the two sliding blocks. Fixing bolts are threaded to the rear side of the sliding blocks. The outer walls of the fixing bolts engage with the outer walls of the limiting grooves. Limiting clamps are fixedly connected to the top of adjacent sides of the two limiting plates. Fastening screws are threaded to the bottom of the two limiting plates. Clamping components are provided on adjacent sides of the two limiting plates.
[0008] The above technical solution involves fixing the scraper structure to the equipment, with the limiting groove providing a sliding track for the sliding block. By sliding the sliding block along the limiting groove, the relative position of the two limiting plates can be flexibly adjusted to adapt to different mounting base sizes. After adjustment, the fixing bolts are tightened to fix the sliding block to the limiting groove, completing the initial positioning. Finally, the fixing screws are tightened to further enhance the clamping force and ensure that the overall structure is stably installed on the equipment and is not easy to loosen.
[0009] As a further description of the above technical solution: The transmission assembly includes a pulley, the inner wall of which is fixedly connected to the right side of the outer wall of the rotating column, and a pulley fixedly connected to the right side of the outer wall of the rotating shaft. Both the inner walls of the pulley and the pulley are provided with transmission belts.
[0010] The above technical solution involves the following: In the transmission assembly, the pulley on the outer wall of the rotating column rotates with the rotating column, and the power is transmitted to the pulley on the right side of the outer wall of the rotating shaft through the transmission belt, thereby driving the rotating shaft to rotate.
[0011] As a further description of the above technical solution: The clamping assembly includes two slide rails, the outer walls of which are respectively fixedly connected to the middle of adjacent sides of the limiting plate, and a sliding clamping plate is slidably connected to the outer wall of the slide rails.
[0012] Through the above technical solution: in the clamping assembly, the sliding clamp slides along the slide rail and cooperates with the limiting clamp to clamp the mounting base from both sides.
[0013] As a further description of the above technical solution: The top of the fastening screw passes through the bottom of the limiting plate and is rotatably connected to the bottom of the sliding clamp. The sliding clamp and the limiting clamp are designed to be corrosion resistant.
[0014] Through the above technical solution: when the fastening screw is turned, the sliding clamp can be moved up and down along the slide rail, thereby adjusting the distance between the sliding clamp and the limit clamp to adapt to the mounting base of different thicknesses. The anti-corrosion design can effectively resist the corrosion of mud, water and chemicals in the working environment, and prevent the clamp from reducing the clamping performance due to rust.
[0015] As a further description of the above technical solution: The scraper is fixedly connected to the left and right sides of the front part, and the partitions and the front side of the scraper are designed to prevent sticking.
[0016] Through the above technical solution: the baffle can prevent the sludge scraped off by the scraper from spreading to both sides, preventing the sludge from falling to other parts of the equipment and causing pollution. At the same time, it confines the sludge to the front area of the scraper. In addition, the anti-sticking design of the baffle and the scraper can reduce the adhesion of sludge to its surface and prevent sludge from accumulating and clumping, which affects the smoothness of sludge scraping.
[0017] As a further description of the above technical solution: The front side of the scraper has multiple guide grooves, which are designed to be narrower at the top and wider at the bottom.
[0018] Through the above technical solution, the guide trough can guide the scraped sludge, allowing the sludge to flow downwards along the path of the trough, preventing the sludge from accumulating randomly on the scraper surface. At the same time, the sludge in the narrower area above gradually disperses as it moves downwards, increasing the flow space and effectively preventing sludge blockage in the trough.
[0019] As a further description of the above technical solution: The cam's protrusions are designed for wear resistance, and the pulley and belt pulley are the same size.
[0020] Through the above technical solutions: the wear-resistant design can significantly enhance the wear resistance of the bumps, reduce dimensional loss after long-term use, and ensure the stability of striking force and frequency. The pulley and belt pulley are the same size, which can ensure that they maintain the same speed during transmission, making the power transmission smoother.
[0021] This utility model has the following beneficial effects: 1. In this utility model, the scraper is made to adhere to the surface of the belt by the contraction spring. When the conveyor belt rotates, the rollers, due to contact with the bottom end of the conveyor belt, drive the rotating column to rotate under the action of friction. The transmission component transmits power to the rotating shaft, which drives the rotating shaft and multiple cams in the middle to rotate. Under the action of the tension spring, the rotating plate makes the rollers and the bottom end of the conveyor belt in close contact. The rotation of the cams indirectly causes the cams to strike the bottom side of the scraper, making the soil adhering to the scraper easier to fall off under vibration, thus improving the sludge scraping effect.
[0022] 2. In this utility model, the sliding block is provided with a track by the limiting groove. The sliding block slides along the limiting groove, and the relative position of the two limiting plates can be flexibly adjusted to adapt to different mounting base sizes. After adjustment, the fixing bolts are tightened to fix the sliding block and the limiting groove, completing the initial positioning. Subsequently, the sliding clamping plate slides along the slide rail and cooperates with the limiting clamping plate to clamp the mounting base from both sides. Finally, the fixing screws are tightened to enhance the clamping force, thereby ensuring that the overall structure is installed stably and is not easy to loosen. Attached Figure Description

[0025] 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.
[0026] Reference Figure 1 , Figure 4 and Figure 5 The present invention provides an embodiment of a belt scraper for a plate and frame filter press, comprising two support rods 1, with scraper 4 rotatably connected to the adjacent top sides of the two support rods 1, and compression springs 7 rotatably connected to the left and right sides of the outer wall of the scraper 4. The support rods 1 provide stable support for the overall structure, and the compression springs 7, by their own elastic tension, keep the scraper 4 in close contact with the belt surface. The bottom ends of the compression springs 7 are rotatably connected to the bottom ends of the corresponding support rods 1. A striking mechanism 2 is provided on the rear side of the support rods 1, and a quick installation mechanism 3 is provided on the bottom end of the support rods 1. The striking mechanism 2 includes a rotating shaft 201, with its left and right ends rotatably connected to the middle of adjacent sides of two support rods 1. Multiple cams 202 are fixedly connected to the middle of the outer wall of the rotating shaft 201. Rotating plates 204 are rotatably connected to both the left and right sides of the outer wall of the rotating shaft 201. A limiting rod 203 is fixedly connected to the rear top of each support rod 1. A tension spring 208 is provided on the outer wall of the limiting rod 203. The top ends of the tension springs 208 engage with the outer walls of the corresponding limiting rods 203, and the bottom ends engage with the middle of the outer walls of the corresponding rotating plates 204. Rotating columns 205 are rotatably connected to the rear of adjacent sides of the two rotating plates 204. The multiple cams 202 in the middle of the rotating shaft 201 also rotate synchronously. Under the tension of the tension springs 208, the rotating plates 204... The limiting rod 203 provides a top fixing point for the tension spring 208, which always maintains the tendency to rotate upwards, ensuring that the roller 206 is firmly in contact with the bottom of the conveyor belt, thus ensuring stable power transmission. At the same time, the cam 202 will periodically push the rotating plate 204 during rotation, which, together with the tension of the tension spring 208, causes the rotating plate 204 to oscillate back and forth, driving the rotating column 205 and the roller 206 to indirectly cause the cam 202 to continuously strike the bottom side of the scraper 4. The roller 206 is rotatably connected to the left and right sides of the middle of the outer wall of the rotating column 205. When the plate and frame filter starts, the conveyor belt above it begins to rotate. Because the roller 206 is in contact with the bottom of the conveyor belt, it is driven to rotate synchronously under the action of friction, thereby causing the rotating column 205 to rotate as well. A transmission component 207 is provided on the right side of the outer wall of the rotating column 205. The transmission assembly 207 includes a pulley 2071, the inner wall of which is fixedly connected to the right side of the outer wall of the rotating column 205. A pulley 2073 is fixedly connected to the right side of the outer wall of the rotating shaft 201. Both the inner walls of the pulley 2071 and the pulley 2073 are provided with a transmission belt 2072. The pulley 2071 on the right side of the outer wall of the rotating column 205 rotates with the rotating column 205 and transmits power to the pulley 2073 on the right side of the outer wall of the rotating shaft 201 through the transmission belt 2072. Specifically, support rod 1 provides stable support for the overall structure. The contraction spring 7, through its own elastic tension, keeps scraper 4 in close contact with the belt surface, continuously scraping away sludge from the belt. When the plate and frame filter press starts, the conveyor belt above it begins to rotate. Because roller 206 contacts the bottom end of the conveyor belt, it is driven to rotate synchronously under friction, causing the rotating column 205 to rotate accordingly. In the transmission assembly 207, the pulley 2071 on the right side of the outer wall of the rotating column 205 rotates with the rotating column 205, transmitting power to the pulley 2073 on the right side of the outer wall of the rotating shaft 201 via the transmission belt 2072, driving the rotating shaft 201 to rotate. The rotating shaft 201... Multiple cams 202 of the part also rotate synchronously. Under the tension of the tension spring 208, the rotating plate 204 maintains a tendency to rotate upward, ensuring that the roller 206 is firmly in contact with the bottom of the conveyor belt and ensuring stable power transmission. At the same time, the cam 202 will periodically push the rotating plate 204 during rotation, which, together with the tension of the tension spring 208, makes the rotating plate 204 swing back and forth, driving the rotating column 205 and the roller 206 to indirectly make the cam 202 continuously hit the bottom side of the scraper 4. When there is soil stuck on the scraper 4, it is easier to fall off under the vibration, improving the mud scraping effect.
[0027] Reference Figure 3 , Figure 4 and Figure 5 The quick-installation mechanism 3 includes two limiting grooves 301. The outer walls of the two limiting grooves 301 are formed at the bottom of the support rod 1. The limiting grooves 301 provide sliding tracks for the sliding blocks 302. The sliding blocks 302 are slidably connected to the inner walls of the limiting grooves 301. Each adjacent side of the two sliding blocks 302 is fixedly connected to a limiting plate 303. The relative position of the two limiting plates 303 can be flexibly adjusted by sliding the sliding blocks 302 along the limiting grooves 301. The rear side of the sliding blocks 302 is threaded with a fixing bolt 30. 4. The outer wall of the fixing bolt 304 engages with the outer wall of the limiting groove 301. After adjustment, tighten the fixing bolt 304 to fix the sliding block 302 to the limiting groove 301, thus completing the initial positioning. The top of each adjacent side of the two limiting plates 303 is fixedly connected to a limiting clamping plate 305. The bottom of each of the two limiting plates 303 is threaded with a fastening screw 307. Tighten the fastening screw 307 to further enhance the clamping force. Each adjacent side of the two limiting plates 303 is provided with a clamping component 306. The clamping assembly 306 includes two slide rails 3062. The outer walls of the two slide rails 3062 are respectively fixedly connected to the middle of adjacent sides of the limiting plate 303. The outer walls of the slide rails 3062 are slidably connected to sliding clamping plates 3061. The sliding clamping plates 3061 slide along the slide rails 3062 and cooperate with the limiting clamping plates 305 to clamp the mounting base from both sides. Specifically, the scraper structure is fixed to the equipment. The limiting groove 301 provides a sliding track for the sliding block 302. By sliding the sliding block 302 along the limiting groove 301, the relative position of the two limiting plates 303 can be flexibly adjusted to adapt to the size of different mounting bases. After adjustment, the fixing bolts 304 are tightened to fix the sliding block 302 to the limiting groove 301, completing the initial positioning. In the clamping assembly 306, the sliding clamping plate 3061 slides along the slide rail 3062 and cooperates with the limiting clamping plate 305 to clamp the mounting base from both sides. Finally, the fixing screws 307 are tightened to further enhance the clamping force and ensure that the overall structure is stably installed on the equipment and is not easy to loosen.
[0028] Reference Figure 1 , Figure 2 and Figure 4 The top of the fastening screw 307 passes through the bottom of the limiting plate 303 and is rotatably connected to the bottom of the sliding clamp 3061. This allows the sliding clamp 3061 to move up and down along the slide rail 3062 when the fastening screw 307 is rotated, thus precisely adjusting the distance between the sliding clamp 3061 and the limiting clamp 305. Both the sliding clamp 3061 and the limiting clamp 305 are designed to resist corrosion, effectively resisting the corrosion of sludge, moisture, and chemicals in the working environment, preventing the clamps from reducing their clamping performance due to rust. Partition plates 5 are fixedly connected to the left and right sides of the front of the scraper 4. The partition plates 5 prevent the sludge scraped off by the scraper 4 from spreading to both sides, preventing sludge from falling to other parts of the equipment and causing pollution. The partition plates 5 and the scraper 4... The front side features an anti-sticking design to reduce sludge adhesion to its surface and prevent sludge buildup and clumping that could affect the smoothness of scraping. Multiple guide grooves 6 are provided on the front side of the scraper 4. These grooves guide the scraped sludge, allowing it to flow downwards along the groove path. The guide grooves 6 are narrower at the top and wider at the bottom, allowing the sludge in the narrower upper area to gradually disperse as it moves downwards, increasing the flow space and effectively preventing sludge blockage within the groove. The cam 202's protrusions feature a wear-resistant design, significantly enhancing their wear resistance and reducing dimensional wear after long-term use. The pulley 2071 and belt pulley 2073 are the same size, ensuring they maintain the same rotational speed during transmission, resulting in smoother power transmission. Specifically, the top of the fastening screw 307 passes through the bottom of the limiting plate 303 and is rotatably connected to the bottom of the sliding clamp 3061. This allows the sliding clamp 3061 to move up and down along the slide rail 3062 when the fastening screw 307 is rotated, precisely adjusting the distance between the sliding clamp 3061 and the limiting clamp 305 to accommodate mounting bases of different thicknesses and ensure secure clamping. The sliding clamp 3061 and the limiting clamp 305 are designed to resist corrosion from sludge, moisture, and chemicals in the working environment, preventing the clamps from losing clamping performance due to rust, extending their service life, and ensuring the long-term stability of the installation structure. The partition 5 prevents the sludge scraped off by the scraper 4 from spreading to both sides, preventing sludge from falling to other parts of the equipment and causing pollution. It also confines the sludge to the area in front of the scraper 4 for easy collection and treatment. Furthermore, the partition 5 and the front of the scraper 4 are designed to prevent sludge from sticking together, reducing sludge buildup. The adhesion to its surface prevents sludge from accumulating and clumping, thus avoiding smooth scraping, reducing the frequency of manual cleaning, and maintaining efficient scraping operations. The guide groove 6 guides the scraped sludge, allowing it to flow downwards along the groove path, preventing sludge from accumulating randomly on the surface of the scraper 4. At the same time, the sludge in the narrower upper area gradually disperses as it moves downwards, increasing the flow space and effectively preventing sludge from clogging in the groove. This ensures that the sludge can smoothly slide into the collection device. The cam 202's protrusions are designed to be wear-resistant, significantly enhancing their wear resistance, reducing dimensional wear after long-term use, ensuring the stability of the striking force and frequency, and maintaining a good vibration desliming effect. The pulley 2071 and the belt pulley 2073 are the same size, ensuring that they maintain the same speed during transmission, making power transmission smoother and avoiding slippage and uneven tension of the transmission belt 2072 due to speed differences.
[0029] Working principle: First, the support rod 1 provides stable support for the overall structure. The compression spring 7, relying on its own elastic tension, keeps the scraper 4 in close contact with the belt surface, continuously scraping away the sludge on the belt. After the plate and frame filter press starts, the conveyor belt above it begins to rotate. Because the roller 206 is in contact with the bottom end of the conveyor belt, it is driven to rotate synchronously under the action of friction, which in turn causes the rotating column 205 to rotate. In the transmission assembly 207, the pulley 2071 on the right side of the outer wall of the rotating column 205 rotates with the rotating column 205. Through the transmission belt 2072, the power is transmitted to the pulley 2073 on the right side of the outer wall of the rotating shaft 201, driving the rotating shaft 201 to rotate. The middle part of the rotating shaft 201 Multiple cams 202 rotate synchronously. Under the tension of the tension spring 208, the limiting rod 203 provides the top fixing point for the tension spring 208, so that it always maintains the tendency to rotate upward, ensuring that the roller 206 is in close contact with the bottom of the conveyor belt, ensuring stable power transmission. At the same time, the cams 202 will periodically push the rotating plate 204 during rotation, which, together with the tension of the tension spring 208, makes the rotating plate 204 swing back and forth, driving the rotating column 205 and the roller 206, indirectly causing the cams 202 to continuously strike the bottom side of the scraper 4. When there is mud stuck on the scraper 4, it is easier to fall off under the vibration, thereby improving the mud scraping effect. Furthermore, the scraper structure is fixed to the equipment via the quick-installation mechanism 3. The limiting groove 301 provides a sliding track for the sliding block 302. By sliding the sliding block 302 along the limiting groove 301, the relative position of the two limiting plates 303 can be flexibly adjusted to adapt to the size of different mounting bases. After adjusting to the appropriate position, the fixing bolts 304 are tightened to fix the sliding block 302 to the limiting groove 301, completing the initial positioning. In the clamping assembly 306, the sliding clamping plate 3061 slides along the slide rail 3062 and cooperates with the limiting clamping plate 305 to clamp the mounting base from both sides. Finally, the fixing screws 307 are tightened to further enhance the clamping force and ensure that the overall structure is stably installed on the equipment and is not easy to loosen.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
