Description

Technical Field

[0001] The present invention relates to the technical field of chemical production, and particularly relates to a filtering device for chemical industry. Background Art

[0002] In the process of chemical production, material filtration is one of the key technological links. Chemical materials sometimes get contaminated with other impurities or coagulate into larger lumps, which is not conducive to subsequent use and will directly affect product quality and production efficiency. Traditional chemical filtering devices mostly adopt fixed sieve meshes or vibrating sieve structures to achieve impurity filtration through physical screening. However, the following significant problems exist in the prior art: When dealing with highly viscous or caked materials, unbroken lumps are likely to block the pores of the sieve mesh, resulting in a sharp decline in filtration efficiency. Frequent shutdowns are required for cleaning, which seriously restricts continuous production. Most equipment needs to be additionally equipped with pre-crushing devices, leading to complex process flows, large floor areas of equipment, and some vibrating filtering devices only filter through a single filtering mechanism, with poor filtering effects. Repeated filtration or the cooperation of multiple filtering devices is required to operate simultaneously, with complex steps and being rather cumbersome. It is difficult for the equipment to operate in coordination, resulting in not only low production efficiency but also high energy consumption. Summary of the Invention

A plurality of openings 244 are evenly formed in the outer wall of the secondary fixing plate 241. The main gear 233 meshes with the secondary gear 238, and the secondary gear 238 meshes with the tooth ring 243. Materials can be put into the stirring and screening mechanism 2 through the plurality of openings 244. When the equipment is running, the required chemical materials to be filtered can also be continuously added into the stirring and screening mechanism 2 through the plurality of openings 244. Then, the motor 22 is started to drive the rotating shaft 232 to rotate at a high speed, driving the stirring blade 236 on the loading cylinder 234 to cut and crush the materials. The main gear 233 at the end of the rotating shaft 232 meshes with the secondary gear 238, and the secondary gear 238 further meshes with the tooth ring 243 on the inner wall of the sieve cylinder 242 to drive the sieve cylinder 242 to rotate synchronously. The crushed materials are dispersed in the sieve cylinder 242 with the rotating centrifugal force. The qualified fine materials fall through the sieve pores and fall on the filter plate 578 through the feeding port 59, while the large particles are intercepted and continue to be crushed.

[0012] Both the left and right ends of the loading cylinder 234 are fixedly connected with limiting disks 237. The main gear 233 is arranged between the loading cylinder 234 and the main fixed plate 231. The secondary gear 238 is rotatably connected to a non-central point position on the side of the main fixed plate 231 away from the motor 22.

The splash-proof scraping plate 8 is arranged between the two rod brackets 6. One side of the splash-proof scraping plate 8 is closely attached to the surface of the screen cylinder 242. The two rotating wheels 9 are respectively arranged on the sides of the two rod brackets 6 away from the splash-proof scraping plate 8. The splash-proof scraping plate 8 is closely attached to the surface of the screen cylinder 242, scraping off the adhering materials in real time to prevent blockage, and at the same time preventing the crushed chemical materials from being thrown out when the screen cylinder 242 rotates. The splashed chemical materials slide onto the guiding plate 10 after being blocked by the splash-proof scraping plate 8, which is convenient for unified recycling and reuse.

[0014] The shaking and filtering mechanism 5 includes a bottom box 51 fixedly connected to the inner wall of the middle part of the frame body 1, a linkage shaking and filtering component 57 fixedly connected to the middle part of the right side of the front end of the frame body 1, and a discharge port 55 opened on the lower side of the bottom box 51. An inlet 59 is opened on the upper side of one end of the bottom box 51 close to the guiding plate 10. A through port 54 is opened on the upper part of the front side of the bottom box 51. A discharge port 53 is opened in the middle of the rear side of the bottom box 51. The height of the discharge port 53 is lower than the height of the through port 54. The lower end of the arc plate 11 is arranged on the upper side of the rear end of the inlet 59. The height of the discharge port 53 is lower than that of the through port 54, ensuring the smooth discharge of larger-volume residues.

[0015] The linkage shaking and filtering component 57 includes a bracket 571 fixedly connected to the middle part of the right side of the front end of the frame body 1, a shaft rod 573 rotatably connected to the lower end of the bracket 571, and a pulley one 574 fixedly connected to the end of the shaft rod 573 away from the frame body 1.

A pulley two 575 is fixedly connected to the end of the fixed connection rod 572 away from the rotating shaft 232. The outer walls of the pulley two 575 and the pulley one 574 are connected by a synchronous belt 576.

[0016] One end of the shaft rod 573 close to the frame body 1 is fixedly connected with a turntable 577. One side of the turntable 577 close to the frame body 1 is fixedly connected with a fixed column block 5712. The fixed column block 5712 is fixedly connected at a non-central point position on the side of the turntable 577 close to the frame body 1.

[0017] Support strip blocks 58 are fixedly connected to the inner walls of the middle parts of the left and right sides of the bottom box 51. The same filter plate 578 is slidably connected to the upper sides of the two support strip blocks 58. The rear end of the filter plate 578 is arranged in the middle of the discharge port 53, and the front end of the filter plate 578 is arranged in the middle of the through port 54. A fixed connection strip 579 is fixedly connected to the middle part of the right side of the filter plate 578. A strip opening 52 is formed in the middle of the right side of the bottom box 51. The fixed connection strip 579 is slidably connected to the middle of the strip opening 52. The screened chemical materials are guided by the arc plate 11 into the feeding port 59 of the bottom box 51 of the vibrating filtering mechanism 5. The rotating shaft 232 drives the belt pulley two 575 to rotate through the fixed connection rod 572, and drives the belt pulley one 574 and the shaft rod 573 to rotate through the synchronous belt 576, so that the turntable 577 rotates. As the turntable 577 rotates, the fixed column block 5712 rotates around the center and reciprocates. The fixed column block 5712 reciprocates in the positioning frame 5711, and drives the filter plate 578 to reciprocate along the support strip block 58 through the connecting rod 5710 and the fixed connection strip 579, so as to achieve the purpose of vibrating filtration. The continuous vibration of the filter plate 578 accelerates the flow of smaller particles in the material through the pores of the filter plate into the discharge port 55, and the larger solid residues move towards the discharge port 53 and are discharged along with the vibration.

[0018] A connecting rod 5710 is fixedly connected to the middle part of the side of the fixed connection strip 579 away from the filter plate 578. One end of the connecting rod 5710 away from the fixed connection strip 579 is fixedly connected with a positioning frame 5711. The fixed column block 5712 is arranged in the middle of the positioning frame 5711. A limiting frame 56 is fixedly connected to the outer wall of a section of the strip opening 52 close to the through port 54. The connecting rod 5710 is arranged in the middle of the limiting frame 56. The fixed connection strip 579 is in the middle of the strip opening 52, which can prevent the filter plate 578 from accidentally shifting. The connecting rod 5710 is arranged in the middle of the limiting frame 56, which can make the filter plate 578 move reciprocally along a specific route.

[0019] Working principle: The present invention integrates a stirring and screening mechanism 2 and a shaking and filtering mechanism 5 to achieve continuous crushing, dynamic screening, and efficient solid-liquid separation of materials. The materials can be put into the stirring and screening mechanism 2 through multiple openings 244. During the operation of the equipment, the required chemical materials to be filtered can also be continuously added into the stirring and screening mechanism 2 through the multiple openings 244. Subsequently, the motor 22 is started to drive the rotating shaft 232 to rotate at a high speed, driving the stirring blades 236 on the loading cylinder 234 to cut and crush the materials. The main gear 233 at the end of the rotating shaft 232 meshes with the sub-gear 238, and the sub-gear 238 further meshes with the tooth ring 243 on the inner wall of the screen cylinder 242, driving the screen cylinder 242 to rotate synchronously. The crushed materials are dispersed in the screen cylinder 242 under the rotating centrifugal force. The qualified fine materials fall through the screen pores and land on the filter plate 578 through the feed inlet 59, while the large particles are intercepted and continue to be crushed. The anti-splash scraper 8 closely adheres to the surface of the screen cylinder 242, scraping off the adhered materials in real time to prevent blockage, and at the same time preventing the screen cylinder 242 from throwing out the crushed chemical materials during rotation and splashing. The splashed chemical materials slide onto the guiding plate 10 after being blocked by the anti-splash scraper 8, which is convenient for unified recovery and reuse. The screened chemical materials are guided by the arc plate 11 into the feed inlet 59 of the bottom box 51 of the shaking and filtering mechanism 5. The rotating shaft 232 drives the second pulley 575 to rotate through the fixed connection rod 572, driving the first pulley 574 and the shaft rod 573 to rotate through the synchronous belt 576, causing the turntable 577 to rotate. As the turntable 577 rotates, the fixed column block 5712 rotates around the center and reciprocates. The fixed column block 5712 reciprocates in the positioning frame 5711, and drives the filter plate 578 to reciprocate along the support bar block 58 through the connecting rod 5710 and the fixed connection strip 579, so as to achieve the purpose of shaking and filtering. The fixed connection strip 579 is in the middle of the strip opening 52, which can prevent the filter plate 578 from accidentally shifting. The connecting rod 5710 is arranged in the middle of the limiting frame 56, which can make the filter plate 578 reciprocate along a specific route. The continuous shaking of the filter plate 578 accelerates the flow of smaller particles in the materials through the pores of the filter plate into the discharge port 55, while the larger solid residues move towards the discharge port 53 with the shaking and are discharged. The height of the discharge port 53 is lower than that of the through port 54 to ensure the smooth discharge of larger volume residues. A single motor 22 simultaneously drives the crushing, screening, and shaking and filtering actions, and realizes efficient power distribution through transmission components such as gears and synchronous belts, reducing energy consumption. The coordinated movement of the screen cylinder 242 and the filter plate 578, combined with the cleaning effect of the anti-splash scraper 8, significantly reduces the risk of blockage and ensures continuous production. Integrating the functions of crushing, screening, and shaking and filtering simplifies the process flow, reduces the floor area of the equipment. The single-motor drive of multiple mechanisms reduces energy consumption and maintenance costs. The cooperation between the dynamic screen and the shaking and filtering mechanism improves the filtering efficiency and material adaptability, especially suitable for high-viscosity or easily caking chemical materials.
