Description

Technical Field

[0001] The present invention relates to the field of ball mills, and particularly to a ball mill with a negative pressure dust removal and purification function. Background Art

[0002] A ball mill is a key device for further pulverizing materials after they are crushed. It is widely used in industries such as cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics, for dry or wet grinding of various ores and other grindable materials. The ball mill is suitable for grinding various ores and other materials and is widely used in industries such as beneficiation, building materials, and chemical engineering. During the operation of the ball mill, since the particle size of the crushed materials is relatively small, usually measured in microns, a large amount of dust is usually generated at the feeding end and the discharging end. Generally, the ball mill is equipped with air draft dust removal mechanisms at the feeding end and the discharging end to prevent dust diffusion and reduce dust pollution. However, because the particle size of the crushed materials is small and the air draft dust removal mechanisms are not completely sealed with the feeding end or the discharging end, it is inevitable that some dust is not removed in time and diffuses into the surrounding environment and gradually settles on other carriers, such as the outer surface of the cylinder body of the ball mill. If it is not cleaned for a long time, over time, the dust will continuously accumulate layer by layer on the outer surface of the cylinder body, adhering to the outer surface of the cylinder body, making it more troublesome, time-consuming, and laborious to clean later. At the same time, dust will be generated again during cleaning, causing environmental pollution.

[0003] When cleaning the dust on the outer surface of the cylinder body, negative pressure can be formed by using a blower to suck air, and the dust is adsorbed and then filtered. However, simply sucking air often cannot clean it thoroughly. The rotation of the ball mill can be used to generate power to brush the surface of the cylinder body, brushing up the dust on the surface of the cylinder body to make it clean. When sucking and filtering the dust, the filter component is often prone to blockage, which will affect the dust removal effect. Therefore, it is best to set up a device that can clean the filter component to extend the service life of the device. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: A ball mill with a negative pressure dust removal and purification function according to the present invention includes a support, a support plate is fixedly connected to the top of the support, a transmission member is slidably connected to the inner wall of the support, a ball mill is fixedly connected to the side of the transmission member, a bottom plate is fixedly connected to the bottom of the support, a dust suction member is fixedly connected to the top of the support plate, a cleaning member is slidably connected to the inner wall of the dust suction member, and an adjustment member is fixedly connected to the side of the cleaning member. The present device is provided with a cleaning member, and the cleaning member obtains power from the rotating ball mill cylinder through the transmission member. Since the outer surface of the ball mill cylinder does not always require dust removal, when dust removal and cleaning are not required, the transmission member can cut off the power to save energy, reduce the wear of the cleaning member, and extend the service life of the device. The cleaning member can also clean the filter plate in the filtering member. Timely cleaning of the filter plate can prevent the filter plate from being blocked, ensure the dust removal effect, and extend the service life of the device.

[0005] Further, the transmission member includes a spring, the side of the spring is fixedly connected to the support, one end of the spring away from the support is fixedly connected to a pull plate, the pull plate is slidably connected to the support near one end of the support, a snap ring is fixedly connected to the side of the pull plate away from the support, a friction disc is fixedly connected to the inner wall of the snap ring, a bevel gear is fixedly connected to the outside of the friction disc, a friction plate is slidably connected to the side of the friction disc away from the snap ring, a transmission disc is fixedly connected to the side of the friction plate away from the friction disc, the transmission disc away from the friction plate is fixedly connected to the ball mill, a pry bar is rotatably connected to the outside of the pull plate, and one end of the pry bar away from the pull plate is rotatably connected to the support. In a general state, the friction plate is in contact with the friction disc. The rotating ball mill cylinder will drive the friction plate to rotate through the transmission disc to provide power for the cleaning member. When the position of the cleaning member needs to be adjusted, or when dust removal and cleaning are not required, the pry bar can be rotated to drive the pull plate to move towards the support, thereby driving the friction disc to disengage from the friction plate and cutting off the power, which is convenient for adjusting the position of the cleaning member. Cutting off the power when dust removal is not required can save energy, reduce the wear of the cleaning member, and extend the service life of the device.

[0006] Furthermore, the cleaning member includes a cleaning bracket. Both ends of the cleaning bracket are slidably connected to the dust suction member. A middle rod is rotatably connected to the inner wall of the cleaning bracket. A cleaning brush is fixedly connected to the top of the middle rod. The cleaning brush at the top of the middle rod can be used to clean the filtering member when needed. A belt pulley is fixedly connected to the bottom of the middle rod. A belt is rotatably connected to the outer surface of the belt pulley. A driven wheel is rotatably connected to the inner wall of the belt. A support rod is fixedly connected to the bottom of the belt pulley. A limit key is fixedly connected to the bottom of the support rod. A driven gear is slidably connected to the outer surface of the limit key. The side surface of the driven gear is engaged with a bevel gear. A cleaning brush is fixedly connected to the bottom of the limit key. The driven gear is engaged with the bevel gear. The bevel gear drives the driven gear to rotate. The driven gear drives the support rod, the belt pulley, the middle rod and the cleaning brush to rotate through the limit key. The belt pulley drives the other driven wheels to rotate through the belt, that is, drives the other cleaning brushes to rotate. The cleaning brush located at the bottom cleans the outer surface of the cylinder body of the ball mill to ensure the dust removal effect. The cleaning member uses the power of the ball mill to clean the cylinder body and the dust suction member, improves the dust removal effect, can prevent the filter plate in the dust suction member from being blocked, and saves energy.

[0007] Furthermore, the dust suction member includes a dust suction hood. Both ends of the dust suction hood are fixedly connected to the support plates. A chute is clamped on the outer surface of the dust suction hood. A first half partition is slidably connected to the side surface of the dust suction hood. The first half partition can be pulled out from the outside of the dust suction hood. A fan is fixedly connected to the top of the dust suction hood. A filter plate is arranged at the bottom of the fan. The side surface of the filter plate is fixedly connected to the dust suction hood. T-shaped sliding keys are fixedly connected to both ends of the inner wall of the dust suction hood. The outer surface of the T-shaped sliding keys is slidably connected to the cleaning bracket. The cleaning bracket can slide up and down on the T-shaped sliding keys. A dust collecting channel is communicated with one side of the dust suction hood far away from the first half partition. A longitudinal partition is slidably connected to one end of the dust collecting channel close to the dust suction hood. A second half partition is slidably connected to the bottom of the dust collecting channel. A dust collecting bag is fixedly connected to the inner wall of the dust collecting channel. When dust removal and ash cleaning are required for the outer surface of the ball mill cylinder body, the first half partition and the second half partition can be pulled outwards to connect the fan with the bottom of the dust suction hood. The bevel gear drives the cleaning brush to rotate, sweeps up the dust on the cylinder body surface. The fan draws air to form negative pressure, sucks up the dust, filters and adsorbs it on the lower surface of the filter plate through the filter plate. The purified air is discharged from the fan. After the dust on the cylinder body surface is cleaned, the first half partition and the second half partition can be closed to cut off the connection between the fan and the bottom of the dust suction hood, pull up the longitudinal partition to connect the dust collecting channel with the fan, turn the fan over, lift the cleaning member to clean the bottom of the filter plate. The fan blows the cleaned dust into the dust collecting channel to be collected by the dust collecting bag, timely cleans the filter plate, can prevent the filter plate from being blocked, ensures the dust removal effect and efficiency, and prolongs the service life of the device.

[0008] Further, the structure-adjusting member includes a sliding rod, the bottom of the sliding rod is fixedly connected to the bottom plate, the top of the sliding rod is slidably connected with a lifting rod, the side surface of the lifting rod is threadedly connected with a lifting member, and the adjusting member here drives the lifting rod to adjust the position of the driven gear. The lifting member includes a stud, the outer surface of the stud is threadedly connected with the lifting rod, the top of the stud is rotatably connected with a top plate, the bottom of the stud is fixedly connected with a hand wheel, one end of the stud close to the hand wheel is rotatably connected with a fixed plate, the end of the fixed plate away from the stud is fixedly connected with an H-shaped bracket, the top of the H-shaped bracket is fixedly connected with a lifting member, the outer surface of the lifting member is threadedly connected with an adjusting rod, and the end of the adjusting rod away from the lifting member is fixedly connected with a cleaning bracket. The lifting member here adjusts the position of the cleaning bracket through the adjusting rod, that is, adjusts the height of the cleaning brush. The end of the lifting rod away from the sliding rod is rotatably connected to the bottom of the driven gear. Rotating the hand wheel in the lifting member drives the stud to rotate, and then the driven gear can be driven to lift or lower by the lifting rod, or the cleaning bracket can be driven to lift or lower by the adjusting rod. When dust removal is required on the outer surface of the cylinder body of the ball mill, rotate the lifting member connected to the adjusting rod to drive the cleaning bracket to descend so that the cleaning brush contacts the cylinder body, and the cleaning brush can clean the ash on the surface of the cylinder body. When it is necessary to clean the lower surface of the filter plate, drive the cleaning bracket to rise so that the cleaning brush located above contacts the lower surface of the filter plate to clean the lower surface of the filter plate. When the ash cleaning is completed and the power can be cut off, rotate the lifting member connected to the lifting rod to drive the driven gear to rise and disengage from the bevel gear, and the power can be cut off. The positions of the cleaning brush and the driven gear can be flexibly adjusted, the rotation of the cylinder body can be used to provide power for the cleaning and dust suction member and the ball mill, the power can be cut off in time, and the cleaning brush can be lifted to reduce the contact between the brush and the cylinder body, which can save energy, reduce the wear of the cleaning brush, and improve the service life of the device.

[0009] The beneficial effects of the present invention are as follows: 1. By setting up the cleaning member, the cleaning member obtains power from the rotating cylinder body of the ball mill through the transmission member. Since dust removal is not required on the outer surface of the cylinder body of the ball mill all the time, when ash cleaning and dust removal are not required, the transmission member can cut off the power to save energy, reduce the wear of the cleaning member, and extend the service life of the device. The cleaning member can also clean the filter plate in the filtering member, clean the filter plate in time, prevent the filter plate from being blocked, ensure the dust removal effect, and extend the service life of the device.

[0010] 2. By providing a transmission member in the present invention, in the normal state, the friction plate is in contact with the friction disc. The rotating cylinder of the ball mill drives the friction plate to rotate through the transmission disc, providing power for the cleaning member. When the position of the cleaning member needs to be adjusted, or when dust removal is not required, the pry bar can be rotated to drive the pull disc to move towards the support, thereby driving the friction disc away from the friction plate and cutting off the power. This facilitates the adjustment of the position of the cleaning member. Cutting off the power when dust removal is not needed can save energy, reduce the wear of the cleaning member, and extend the service life of the device.

[0011] 3. By providing an ash suction member in the present invention, when dust removal is performed on the cylinder, the first half partition and the second half partition can be pulled outwards, so that the fan is communicated with the bottom of the ash suction cover. The bevel gear drives the cleaning brush to rotate, sweeping up the dust on the surface of the cylinder. The fan draws air to form a negative pressure, sucking up the dust, which is filtered by the filter plate and adsorbed on the lower surface of the filter plate. The purified air is discharged from the fan. When the dust on the surface of the cylinder is cleaned, the first half partition and the second half partition can be closed to cut off the communication between the fan and the bottom of the ash suction cover. The longitudinal partition is pulled up to connect the dust collection channel with the fan, and the fan is flipped to lift the cleaning member to clean the bottom of the filter plate. The fan blows the cleaned dust into the dust collection channel to be collected by the dust collection bag, cleaning the filter plate in time, preventing the filter plate from being blocked, ensuring the dust removal effect and efficiency, and extending the service life of the device.

[0012] 4. By providing an adjustment structure member in the present invention, when dust removal is required on the outer surface of the cylinder of the ball mill, the lifting member connected to the adjustment rod is rotated to drive the cleaning bracket to descend so that the cleaning brush contacts the cylinder, and the cleaning brush can clean the ash on the surface of the cylinder. When the lower surface of the filter plate needs to be cleaned, the cleaning bracket is driven to rise so that the cleaning brush located above contacts the lower surface of the filter plate to clean the lower surface of the filter plate. When the ash cleaning is completed and the power can be cut off, the lifting member connected to the lifting rod is rotated to drive the driven gear to rise and disengage from the bevel gear, thereby cutting off the power. The positions of the cleaning brush and the driven gear can be flexibly adjusted. The rotation of the cylinder can be used to provide power for the cleaning and ash suction members and the ball mill, and the power can be cut off in time, lifting the cleaning brush to reduce the contact between the brush and the cylinder, saving energy, reducing the wear of the cleaning brush, and improving the service life of the device.

[0021] The specific working process is as follows: After the dust cleaning on the surface of the cylinder body is completed, first stop the fan 64, push the first half partition plate 63 and the second half partition plate 67 inward to cut off the connection between the fan 64 and the bottom of the dust suction hood 61, pull up the longitudinal partition plate 69 to connect the dust collection channel 68 with the fan 64, rotate the pry bar 48 to cut off the power, rotate the lifting member 73 connected to the adjusting rod 75 to drive the cleaning bracket 51 to rise so that the cleaning brush 53 located above contacts the lower surface of the filter plate 65, then the lower surface of the filter plate 65 can be cleaned of dust. The fan 64 rotates in reverse to blow the cleaned dust into the dust collection channel 68 to be collected by the dust collection bag 610. After the dust cleaning of the cylinder body and the filter plate 65 are both completed, the fan 64 can be stopped, and the lifting member 73 connected to the lifting rod 72 is rotated to drive the driven gear 59 to rise and disengage from the bevel gear 45 to cut off the power.
