Description

Technical Field

[0001] The utility model relates to the technical field of devices for preventing ball mill saturation, in particular to a device for preventing ball mill saturation. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are broken. This type of grinding machine is a machine that has a certain number of steel balls as grinding media in its cylinder.

[0003] The inventor found in daily use of the ball mill that after the inorganic powder is ground by the ball mill, the powder is extracted from the ball mill by the action of the Roots blower. However, due to insufficient grinding, short grinding time, and insufficient fineness of the powder, the powder will be blocked when passing through the internal mesh plate of the ball mill when it is extracted. Since the front end of the ball mill is still feeding, and the back end is blocked, the powder in the ball mill cannot be extracted, so that more and more materials are in the grinding chamber, resulting in saturation, which greatly reduces the grinding efficiency and causes an impact. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a device for preventing ball mill from being saturated.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device for preventing ball mill saturation, comprising a bracket, a ball mill is rotatably connected to the side of the bracket, a feed port is rotatably connected to the side of the bracket, a fan is fixedly connected to the side of the bracket, one end of the fan is rotatably connected to the ball mill, a rectangular plate is fixedly connected to the upper top of the bracket, a motor is fixedly connected to the side of the rectangular plate, a rotating shaft is fixedly connected to the output end of the motor, a gear is fixedly connected to the surface of the rotating shaft, a gear is fixedly connected to the surface of the ball mill, the gear ring is meshed with the gear for transmission, a filter is fixedly connected to the inside of the ball mill, a feed control device is arranged inside the ball mill, a cleaning device is arranged inside the ball mill, the feed control device comprises a round rod rotatably connected to the side of the filter, one end of the round rod is fixedly connected to the fan, the other end of the round rod is inserted into the inside of the feed port, and one end of the round rod is fixedly connected to an auger.

[0006] The effects achieved by the above components are: when the fan is started, the fan is driven to rotate, which in turn causes the auger to rotate, so that the powder can enter the interior of the ball mill. When the filter is blocked, the fan cannot extract the powder, and the fan stops rotating, causing the auger to stop rotating, thereby achieving the effect of controlling the feed. When using the ball mill, pour the material into the ball mill through the feed port, start the motor, so that the gear drives the gear ring to rotate, and then the ball mill is operated, and then the material is ground and crushed by the balls inside the ball mill. Start the fan so that the crushed material passes through the filter and enters the interior of the fan for collection.

[0007] Preferably, a sleeve rod is sleeved on the surface of the round rod, one end of the sleeve rod is fixedly connected to the side of the filter screen, and the round rod is rotatably connected inside the sleeve rod.

[0008] The effect achieved by the above components is that under the action of the sleeve rod, the round rod will not be impacted and deformed by the sphere inside the ball mill.

[0009] Preferably, an airbag is fixedly connected to the surface of the sleeve rod, and the interior of the airbag is filled with air.

[0010] The effect achieved by the above components is that, under the action of the airbag, the ball can be buffered when it hits the sleeve rod, thereby achieving a buffering effect.

[0011] Preferably, one end of the auger is fixedly connected to a conical block, and a trapezoidal plate is fixedly connected to the surface of the conical block.

[0012] The effects achieved by the above components are as follows: under the action of the trapezoidal plate and the conical block, the materials accumulated inside the feed port can be broken up, thereby facilitating transportation. After the fan is started, when the filter screen is not blocked by large particles of powder, the fan rotates, and then the auger, the conical block and the trapezoidal plate are driven to rotate through the round rod. Under the action of the trapezoidal plate and the conical block, the materials accumulated inside the feed port can be broken up, thereby facilitating transportation. When the mesh of the filter screen is blocked, the gas inside the ball mill does not circulate, and the fan cannot extract air from the inside of the ball mill, which causes the fan to stop rotating, and the material will not enter the inside of the ball mill. When the ball mill rotates, under the action of the sleeve rod, the round rod will not be impacted and deformed by the sphere inside the ball mill. Under the action of the airbag, the sphere can be buffered when it hits the sleeve rod, thereby achieving a buffering effect, thereby achieving a feeding control effect.

[0013] Preferably, the cleaning device comprises a rectangular groove opened on the inner wall of the ball mill, a fixing rod is fixedly connected to the inside of the rectangular groove, a top plate is slidably connected to the surface of the fixing rod, a top pin is fixedly connected to the side of the top plate, and the maximum diameter of the top pin is larger than the mesh diameter of the filter.

[0014] The effect achieved by the above components is that the mesh holes on the surface of the filter screen are cleaned under the action of the ejector pin and the ejector plate.

[0015] Preferably, a through groove is formed on the surface of the top plate, and the through groove and the ejector pins are arranged alternately.

[0016] The effect achieved by the above components is that, under the action of the through slot, the powder can enter the interior of the fan through the through slot.

[0017] Preferably, a spring is sleeved on the surface of the fixing rod, and two ends of the spring are fixedly connected to the inner wall of the rectangular groove and the side surface of the top plate respectively.

[0018] The effect achieved by the above components is that under the action of the spring, the top plate can be pressed against the side of the filter screen.

[0019] Preferably, a pad is fixedly connected to the side of the top plate, and the pad is a rubber pad.

[0020] The effects achieved by the above components are as follows: under the action of the pad, the side of the top plate will not directly contact the inner wall of the rectangular groove, avoiding the phenomenon of rigid contact. When the mesh of the filter is blocked, under the action of the spring, the top plate and the ejector pin are moved toward the position of the filter, and then the ejector pin is inserted into the interior of the filter to clean the mesh of the filter. When cleaning is completed, the top plate is moved away from the filter under the suction of the fan. Under the action of the pad, the side of the top plate will not directly contact the inner wall of the rectangular groove, avoiding the phenomenon of rigid contact, thereby achieving the cleaning effect.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by setting a controlled feeding device, after the fan is started, when the filter screen is not blocked by large particles of powder, the fan rotates, and then the auger, the conical block and the trapezoidal plate are driven to rotate through the round rod. Under the action of the trapezoidal plate and the conical block, the material accumulated inside the feed port can be broken up, thereby facilitating transportation. When the mesh holes of the filter screen are blocked, the gas inside the ball mill does not circulate, and the fan cannot extract air from the inside of the ball mill, thereby causing the fan to stop rotating, and the material does not enter the inside of the ball mill. When the ball mill rotates, under the action of the sleeve rod, the round rod will not be impacted and deformed by the ball inside the ball mill. Under the action of the airbag, the ball can be buffered when it hits the sleeve rod, thereby achieving the buffering effect, and then achieving the effect of controlling the feeding, thereby solving the problem that there is too much powder inside the ball mill that cannot be ground.
