Description

Technical Field

[0001] The utility model relates to a conveying device, in particular to a feeding and dust removal processing device. Background Art

[0002] In industrial production, for example, in the production of battery cathode and anode materials, powder feeding is often required. During the powder feeding process, relatively serious dust pollution will be generated. Currently, in order to reduce pollution, dust collectors are usually configured near the automatic unpacking type of ton bags and manual feeding stations, which can effectively reduce the dust emission at the front end of feeding. However, when the powder falls into containers such as mixing tanks or grinding tanks at the rear end, a large amount of dust will be raised and fill the pipeline connecting the container, forming a dust spray pipe phenomenon. Even if diaphragm valves and pneumatic butterfly valves are used to block at the front end, a large amount of dust will still be generated during the powder falling process. Therefore, there is an urgent need for a device that can reduce the dust emission at the front end of feeding. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a feeding and dust removal processing device to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A feeding and dust removal processing device includes: a processing device provided with a feed box; a feeding device having a feeding pipe connected to the feed box; a dust removal device including a dust removal pipe, a dust collector, an air pipe and a fan. One end of the dust removal pipe is connected to the feed box, the intake end of the dust collector is connected to the other end of the dust removal pipe, and both ends of the air pipe are respectively connected to the intake end of the fan and the outlet end of the dust collector.

[0006] This technical solution has at least the following beneficial effects: The processing device is used to process the input materials, such as stirring and grinding. A feed box for feeding is provided in the processing device. When the materials need to be processed, the feeding device feeds the materials into the feed box through the feeding pipe. The fan works, and a negative pressure is formed in the dust removal pipe through the dust collector. At this time, the dust raised in the feed box is sucked into the dust removal pipe, and after being dust-removed by the dust collector, it is discharged outwards. In this way, the efficiency of the materials entering the feed box is improved by using negative pressure during feeding, and the dust generated when the materials are put into the feed box can be filtered and exhausted, effectively reducing the dust pollution generated at the rear end of feeding and improving the cleanliness of the production environment.

[0007] As a further improvement of the above technical solution, the dust removal pipe is connected to the top side of the material box and extends upward, and the dust collector is connected to the top end of the dust removal pipe. The dust in the material box enters the dust removal pipe upward, and after being filtered by the dust collector, it is discharged outward. In this way, setting the dust collector above the material box is beneficial to directly recycling the dust filtered by the dust collector into the material box.

[0008] As a further improvement of the above technical solution, the dust collector includes a dust removal housing, a fixing frame, a gas source, a blowing pipe and a corrugated filter bag. A dust removal chamber is formed inside the dust removal housing. An air inlet communicating with the dust removal chamber is formed on the bottom side of the dust removal housing, and an air outlet communicating with the dust removal chamber is formed on the top side of the dust removal housing. The fixing frame is connected inside the dust removal chamber, and a plurality of the corrugated filter bags are connected to the fixing frame. The blowing pipe is connected to the gas source and communicates with the interiors of the plurality of corrugated filter bags. When filtering dust, the airflow with dust passes through the corrugated filter bag and then blows out outside the dust removal housing. The corrugated filter bag can play a main filtering role, and the corrugations of the corrugated filter bag itself can improve the gas filtering effect. After the dust collector is used for a long time, the gas source can blow air into the corrugated filter bag through the blowing pipe. By back-blowing the corrugated filter bag, the dust attached to the outside of the corrugated filter bag can be removed, so that the dust drops into the material box for recycling, which not only realizes the self-cleaning function of the dust collector but also improves the utilization rate of the dust.

[0009] As a further improvement of the above technical solution, a sphere is arranged inside the corrugated filter bag, the outer diameter of the sphere is larger than the inner diameter of the corrugated filter bag, air inlets are respectively arranged at the upper and lower ends of the corrugated filter bag, and the gas source can blow air into the corrugated filter bag through the blowing pipe from the two air inlets respectively. When the corrugated filter bag needs to be self-cleaned, the gas source can alternately blow air into the corrugated filter bag from the two air inlets through the blowing pipe. At this time, the sphere moves up and down inside the corrugated filter bag, and the sphere can expand the part of the corrugated filter bag it passes through outward, improving the efficiency of blowing and dropping the dust from the corrugated filter bag, and the corrugated filter bag refolds and restores under the elastic restoring force after the sphere passes.

[0010] As a further improvement of the above technical solution, vibration generators are respectively connected to the upper and lower ends of the corrugated filter bag on the fixing frame, and an elastic body is connected between the two vibration generators. The two vibration generators can drive the elastic body to generate elastic deformation in the horizontal direction and abut against the inner side of the corrugated filter bag. When the corrugated filter bag needs to be self-cleaned, the two vibration generators can drive the upper and lower ends of the elastic body to generate elastic deformation in the horizontal direction, repeatedly vibrating and hitting the corrugated filter bag from the inner side of the corrugated filter bag, thereby improving the efficiency of blowing and dropping the dust from the corrugated filter bag, and the corrugated filter bag refolds and restores under the elastic restoring force after the sphere passes.

[0011] As a further improvement of the above technical solution, a linear drive is connected to the fixing frame. The linear drive is drivingly connected to a piston. The outer diameter of the piston is larger than the inner diameter of the corrugated filter bag. The linear drive can drive the piston to move up and down. When self-cleaning of the corrugated filter bag is required, the linear drive can drive the piston to move up and down within the corrugated filter bag. The piston can expand the part of the corrugated filter bag it passes through outward, improving the efficiency of blowing dust off the corrugated filter bag and dropping it. After the piston passes, the corrugated filter bag refolds and restores under the elastic restoring force.

[0012] As a further improvement of the above technical solution, a drive motor is connected to the fixing frame. The drive motor is drivingly connected to an eccentric wheel. An offset block is eccentrically connected to the eccentric wheel. The offset block is located within the corrugated filter bag. The drive motor can drive the offset block to rotate along the inner side of the corrugated filter bag through the eccentric wheel. When self-cleaning of the corrugated filter bag is required, the drive motor can drive the offset block to rotate within the corrugated filter bag through the eccentric wheel, repeatedly vibrating and impacting the corrugated filter bag from the inner side, thereby improving the efficiency of blowing dust off the corrugated filter bag and dropping it. After the eccentric block passes, the corrugated filter bag refolds and restores under the elastic restoring force.

[0013] As a further improvement of the above technical solution, the bottom space of the dust removal chamber gradually narrows downward. This can facilitate the downward collection of dust and recycling it into the material box.

[0014] As a further improvement of the above technical solution, a pneumatic butterfly valve is provided on the dust removal pipe. When feeding is required, the dust removal pipe can be opened through the pneumatic butterfly valve, making the dust removal pipe communicate with the inside of the material box. After feeding is completed, the dust removal pipe is closed through the pneumatic butterfly valve to prevent materials from entering the dust removal pipe during processing.

[0015] As a further improvement of the above technical solution, the dust removal pipe and the material box are detachably connected. The dust removal pipe can be disassembled and assembled from the material box, providing convenience for subsequent use and maintenance. Description of the Drawings

Specific embodiments

[0023] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and the attached drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection relationships mentioned in the text do not refer only to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflicting with each other.

[0024] Referring to Figure 1 , a feeding and dust removal processing device includes: a processing device provided with a material box 100, and the processing device is mainly used for processing the input materials, which can be a grinding machine, a dispersing machine or a mixer, etc.; a feeding device 200 having a feeding pipe 210, and the feeding pipe 210 is connected to the material box 100. The feeding device 200 can be a manual feeding station or an automatic feeding station; a dust removal device including a dust removal pipe 310, a dust collector 320, an air duct and a fan 330. One end of the dust removal pipe 310 is connected to the material box 100, the air inlet end of the dust collector 320 is connected to the other end of the dust removal pipe 310, and both ends of the air duct are respectively connected to the air inlet end of the fan 330 and the air outlet end of the dust collector 320.

[0025] In this feeding and dust removal processing equipment, the processing device is used to process the input materials, such as stirring and grinding. A feed bin 100 is provided inside the processing device. When processing the materials is required, the feeding device 200 feeds the materials into the feed bin 100 through the feeding pipe 210. The fan 330 operates, creating a negative pressure in the dust removal pipe 310 through the dust remover 320. At this time, the dust raised in the feed bin 100 is sucked into the dust removal pipe 310, and after being dust-removed by the dust remover 320, it is discharged outwards. In this way, the negative pressure is utilized during feeding to improve the efficiency of the materials entering the feed bin 100, and the dust generated when the materials are put into the feed bin 100 can be filtered and exhausted, effectively reducing the dust pollution generated at the back end of feeding and improving the cleanliness of the production environment.

[0026] The dust removal pipe 310 can be installed at the side wall position of the feed bin 100. In order to facilitate the recovery of the materials in the dust removal pipe 310 into the feed bin 100, in this embodiment, the dust removal pipe 310 is connected to the top side of the feed bin 100 and extends upwards, and the dust remover 320 is connected to the top end of the dust removal pipe 310. The dust in the feed bin 100 enters the dust removal pipe 310 upwards, and after being filtered by the dust remover 320, it is discharged outwards. In this way, by arranging the dust remover 320 above the feed bin 100, it is beneficial to directly recover the dust filtered by the dust remover 320 into the feed bin 100.

[0027] The dust remover 320 is mainly used for filtering gases. It can be a housing with multiple filter meshes arranged along the air flow direction. In order to improve the service life of the dust remover 320, the dust remover 320 can be designed to have a self-cleaning function. Specifically, the dust remover 320 includes a dust removal housing, a fixing frame, a gas source, a blowing pipe, and a corrugated filter bag 321. An air dust removal chamber is formed inside the dust removal housing. An air inlet end communicating with the air dust removal chamber is formed at the bottom side of the dust removal housing, and an air outlet end communicating with the air dust removal chamber is formed at the top side of the dust removal housing. The fixing frame is connected inside the dust removal chamber, and a plurality of the corrugated filter bags 321 are connected to the fixing frame. The blowing pipe is connected to the gas source and communicates with the interiors of the plurality of corrugated filter bags 321. In practical applications, the gas source can be selected from solenoid valves or high-pressure air pumps, etc. When filtering the dust, the airflow with dust passes through the corrugated filter bag 321 and then blows outwards outside the dust removal housing. The corrugated filter bag 321 can play a major filtering role, and the corrugations of the corrugated filter bag 321 itself can improve the effect of gas filtration. After the dust remover 320 is used for a long time, the gas source can blow air into the corrugated filter bag 321 through the blowing pipe. By back-blowing the corrugated filter bag 321, the dust attached to the outer side of the corrugated filter bag 321 can be removed, so that the dust drops into the feed bin 100 for recovery, realizing both the self-cleaning function of the dust remover 320 and improving the utilization rate of the dust.

[0028] To further improve the self-cleaning effect of the dust remover 320, such asFigure 2 As shown, in the first embodiment, a sphere 322 is disposed inside the corrugated filter bag 321. The outer diameter of the sphere 322 is greater than the inner diameter of the corrugated filter bag 321. Air inlets are respectively disposed at the upper and lower ends of the corrugated filter bag 321. The air source can blow air into the corrugated filter bag 321 through the two air inlets via the blowpipe respectively. When self-cleaning of the corrugated filter bag 321 is required, the air source can alternately blow air into the corrugated filter bag 321 through the two air inlets via the blowpipe. At this time, the sphere 322 moves up and down inside the corrugated filter bag 321, and the sphere 322 can expand the part of the corrugated filter bag 321 it passes through outward, improving the efficiency of blowing and dropping dust from the corrugated filter bag 321. After the sphere 322 passes, the corrugated filter bag 321 refolds and restores under the elastic restoring force.

[0029] To further improve the self-cleaning effect of the dust collector 320, as Figure 3 shown, in the second embodiment, vibration generators 323 are respectively connected to the upper and lower ends of the corrugated filter bag 321 on the fixing frame. An elastic body 324 is connected between the two vibration generators 323. The two vibration generators 323 can drive the elastic body 324 to generate elastic deformation in the horizontal direction and abut against the inner side of the corrugated filter bag 321. When self-cleaning of the corrugated filter bag 321 is required, the two vibration generators 323 can drive the upper and lower ends of the elastic body 324 to generate elastic deformation in the horizontal direction, repeatedly vibrating and impacting the corrugated filter bag 321 from the inner side of the corrugated filter bag 321, thereby improving the efficiency of blowing and dropping dust from the corrugated filter bag 321. After the sphere 322 passes, the corrugated filter bag 321 refolds and restores under the elastic restoring force.

[0030] To further improve the self-cleaning effect of the dust collector 320, as Figure 4 shown, in the third embodiment, a linear drive member 325 is connected to the fixing frame. The linear drive member 325 is drivingly connected to a piston 326. The outer diameter of the piston 326 is greater than the inner diameter of the corrugated filter bag 321. The linear drive member 325 can drive the piston 326 to move up and down. The linear drive member 325 can be selected from a cylinder, a lead screw, a hydraulic cylinder, etc. When self-cleaning of the corrugated filter bag 321 is required, the linear drive member 325 can drive the piston 326 to move up and down inside the corrugated filter bag 321. The piston 326 can expand the part of the corrugated filter bag 321 it passes through outward, improving the efficiency of blowing and dropping dust from the corrugated filter bag 321. After the piston 326 passes, the corrugated filter bag 321 refolds and restores under the elastic restoring force.

[0031] To further improve the self-cleaning effect of the dust collector 320, as Figure 5As shown, in the fourth embodiment, a driving motor 327 is connected to the fixing frame. The driving motor 327 is drivingly connected to an eccentric wheel 328. An offset block 329 is eccentrically connected to the eccentric wheel 328. The offset block 329 is located inside the corrugated filter bag 321. The driving motor 327 can drive the offset block 329 to rotate along the inner side of the corrugated filter bag 321 through the eccentric wheel 328. When self-cleaning of the corrugated filter bag 321 is required, the driving motor 327 can drive the offset block 329 to rotate inside the corrugated filter bag 321 through the eccentric wheel 328, repeatedly vibrating and impacting the corrugated filter bag 321 from the inside of the corrugated filter bag 321, thereby improving the efficiency of blowing and dropping dust from the corrugated filter bag 321, and the corrugated filter bag 321 refolds and restores under the elastic restoring force after the eccentric block passes by.

[0032] In some embodiments, the bottom space of the dust removal chamber gradually narrows downward. This can facilitate the downward collection of dust and recycling it into the material box 100.

[0033] In some embodiments, a pneumatic butterfly valve 400 is provided on the dust removal pipe 310. When feeding is required, the dust removal pipe 310 can be opened through the pneumatic butterfly valve 400, so that the dust removal pipe 310 communicates with the inside of the material box 100. After the feeding is completed, the dust removal pipe 310 is closed through the pneumatic butterfly valve 400 to prevent materials from entering the dust removal pipe 310 during processing.

[0034] In some embodiments, the dust removal pipe 310 and the material box 100 are detachably connected. The dust removal pipe 310 can be disassembled and assembled from the material box 100, providing convenience for subsequent use and maintenance.
