Description

Technical Field

[0001] The utility model relates to the technical field of dust treatment, in particular to a granulator dust removing device. Background Art

[0002] A granulator is a device used to process, press or extrude powdered or granular raw materials into granular products. Granulators are usually used in the pharmaceutical, food, chemical, metallurgical and other industries. Granulators can process a variety of different types of raw materials, such as fertilizers, granular chemical products, plastic granules, trees, paper, etc.

[0003] When the granulator uses paper as raw material, a large amount of paper dust will overflow due to the large amount of internal fibers in the paper. At the same time, because there is no good dust collection and treatment device, the dust is large, which is not only easy to cause harm to the health of production personnel, but also reduces work efficiency and easily causes safety hazards. Utility Model Content

[0007] When the granulator works with paper as raw material, one end of the air inlet pipe is passed into the granulator, and then the air pump is started. At this time, the paper dust will enter the interior of the processing box through the air inlet pipe, and then the nozzle starts to work to spray water mist inward. The paper dust will fall when it encounters the water mist, and then flow into the shell through the guide plate. The dust is processed through the cooperation between the collecting components, cleaning components and unloading components, so that the dust no longer floats in the air and causes harm to the staff, and at the same time, the safety hazards are eliminated.

[0008] A further improvement of the technical solution of the utility model is that: the collecting component includes a rotating shaft and a collecting assembly, the outer side of the rotating shaft is fixedly connected with a spiral blade, the outer side of the spiral blade is in contact with the shell, the bottom of the rotating shaft is fixedly connected with a first gear, the top of the first gear is fixedly connected with a guide plate, a notch is provided on the first gear, a shaft body is rotatably connected to the side of the processing box close to the first motor, the end of the shaft body away from the shell is fixedly connected to the output end of the first motor, a support shaft is rotatably connected to the support table, a second gear and bevel teeth are respectively fixedly connected to the support shaft, the first gear is meshed with the second gear, the shaft body is fixedly connected with bevel teeth, and the bevel teeth are meshed with each other.

[0009] The above-mentioned technical scheme is adopted. In this scheme, when paper dust encounters water, it will flow into the shell through the guide plate. At this time, the first motor is started, and the operation of the first motor will drive the shaft body fixedly connected to its output end to rotate. The rotation of the shaft body transmits power to the second gear through the mutual cooperation between the bevel teeth, and the first gear is engaged with the second gear to drive the first gear to rotate. The rotation of the first gear will drive the spiral blade to rotate through the rotating shaft, driving the water-encountered paper dust to move downward along the axis of the rotating shaft to the collection component. At the same time, the rotation of the spiral blade will generate a centrifugal force on the water-encountered paper dust, so that excess water will flow into the dust collection box through the through hole and out from the water outlet pipe, thereby achieving the purpose of facilitating collection.

[0010] A further improvement of the technical solution of the utility model is that: the collecting component includes a box body, the box body is fixedly connected to the support platform, a support column is slidably connected in the box body, an end of the support column close to the box body is fixedly connected to a spring, the other end of the spring is fixedly connected to the box body, the support column is slidably connected to the support platform, an end of the support column away from the spring is fixedly connected to a connecting plate, and the connecting plate is slidably connected to the opening.

When the unloading component unloads the wet paper dust on the connecting plate, the spring will return to its original position.

[0012] A further improvement of the technical solution of the utility model is that the cleaning component includes an electric push rod, the electric push rod is fixedly connected to the support platform, the output end of the electric push rod is fixedly connected to a brush, and the piston rod of the electric push rod is slidably connected to the dust box.

[0013] The above technical solution is adopted. In this solution, when the through hole opened on the shell is blocked, the electric push rod is started at this time, and the electric push rod will drive the brush fixedly connected to its output end to brush back and forth, thereby achieving the purpose of cleaning the shell and clearing the blocked through hole, thereby improving the working efficiency of the device.

[0014] A further improvement of the technical solution of the utility model is that the unloading component includes a sensor, the sensor is fixedly connected to the support table, a transmission shaft is rotatably connected under the support table, a second motor is fixedly connected to the support table, the output end of the second motor is fixedly connected to one end of the transmission shaft, and a processing plate is fixedly connected to the end of the transmission shaft away from the second motor.

[0015] The above-mentioned technical solution is adopted. In this solution, when paper dust accumulates, the spiral blade will continue to rotate to feed downward. When a certain amount is reached, the sensor detects that the support column has moved to the appropriate position, and then starts the second motor. The second motor will drive the processing plate to rotate through the transmission shaft to clean up the paper dust that has encountered water on the connecting plate, and then the support column will be reset under the action of the spring.

[0016] A further improvement of the technical solution of the utility model is that the radius of the second gear is smaller than the radius of the first gear.

[0017] The above technical solution is adopted. In this solution, the radius of the second gear is set smaller than the radius of the first gear because the transmission ratio is relatively large, which can reduce the speed loss during the transmission process, thereby improving the transmission efficiency. At the same time, the speed of the large gear is slower than that of the small gear, which is also conducive to maintaining the operating stability and accuracy of the transmission system.

[0018] A further improvement of the technical solution of the utility model is that a smooth layer is provided on the surface of the guide plate.

[0019] The above technical solution is adopted. In this solution, because dust easily adheres to the surface of the drainage plate after meeting water, thereby forming accumulation and affecting the working efficiency of the device, the probability of dust adhering to the surface of the drainage plate after meeting water can be reduced by providing a smooth layer, thereby improving the working efficiency of the device.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides a granulator dust removal device. When the granulator uses paper as raw material, one end of the air inlet pipe is passed into the granulator, and then the air pump is started.

The paper dust will fall when encountering the water mist, and then flow into the shell through the guide plate. The dust is processed through the cooperation between the collecting component, the cleaning component and the unloading component, so that the dust no longer floats in the air to cause harm to the staff, and the safety hazard is eliminated at the same time.

[0022] 2. The utility model provides a granulator dust removal device. When paper dust meets water, it will flow into the shell through the drainage plate. At this time, the first motor is started. The operation of the first motor will drive the shaft body fixedly connected to its output end to rotate. The rotation of the shaft body transmits power to the second gear through the mutual cooperation between the bevel teeth. The first gear is meshed with the second gear to drive the first gear to rotate. The rotation of the first gear will drive the spiral blade to rotate through the rotating shaft, driving the water-infected paper dust to move downward along the axis of the rotating shaft to the collection component. At the same time, the rotation of the spiral blade will generate a centrifugal force on the water-infected paper dust, so that excess water will flow into the dust collection box through the through hole and flow out from the water outlet pipe, thereby achieving the purpose of facilitating collection.

[0039] When the paper dust meets water, it will flow into the shell 4 through the guide plate 5. At this time, the first motor 6 is started. The operation of the first motor 6 will drive the shaft 15 fixedly connected to its output end to rotate. The rotation of the shaft 15 transmits power to the second gear 17 through the mutual cooperation between the bevel teeth 18. The first gear 13 is meshed with the second gear 17 to drive the first gear 13 to rotate. The rotation of the first gear 13 will drive the spiral blade 11 to rotate through the rotating shaft 12, driving the water-infected paper dust to move downward along the axis of the rotating shaft 12 to the collection component.

[0044] Example 2

[0045] like Figure 3 , Figure 4 As shown, based on Example 1, the utility model provides a technical solution: preferably, an electric push rod is provided inside the processing box 2, the electric push rod is fixedly connected to the support platform 1, a brush 28 is fixedly connected to the output end of the electric push rod, and the piston rod of the electric push rod is slidably connected to the dust collection box 8.

[0047] Example 3

[0048] like Figure 3 As shown, based on Example 2, the utility model provides a technical solution: preferably, the radius of the second gear 17 is smaller than the radius of the first gear 13.

[0049] In this embodiment, the radius of the second gear 17 is set smaller than the radius of the first gear 13 because the transmission ratio is relatively large, which can reduce the speed loss during the transmission process, thereby improving the transmission efficiency. At the same time, the speed of the large gear is slower than that of the small gear, which is also beneficial to maintaining the operating stability and accuracy of the transmission system.

[0050] Example 4

[0051] like Figure 7 As shown, based on Example 3, the utility model provides a technical solution: preferably, a smooth layer 29 is provided on the surface of the guide plate 5.

[0052] In this embodiment, because dust easily adheres to the surface of the drain plate 5 after meeting water, thereby forming accumulation and affecting the working efficiency of the device, the probability of dust adhering to the surface of the drain plate 5 after meeting water can be reduced by providing a smooth layer 29, thereby improving the working efficiency of the device.

[0053] The following is a detailed description of the working principle of the granulator dust removal device.

[0054] like Figure 1-7As shown, when the granulator uses paper as raw material, one end of the air inlet pipe is passed into the granulator, and then the air pump is started. At this time, the paper dust will enter the interior of the processing box 2 through the air inlet pipe, and then the nozzle 3 starts to work to spray water mist inward. The paper dust will fall when it encounters the water mist, and then flow into the shell 4 through the guide plate 5. The dust is processed through the cooperation between the collecting component, the cleaning component and the unloading component, so that the dust no longer floats in the air and causes harm to the staff, and at the same time, the safety hazard is eliminated. When the paper dust meets water, it will flow into the housing 4 through the drainage plate 5. At this time, the first motor 6 is started. The operation of the first motor 6 will drive the shaft 15 fixedly connected to its output end to rotate. The rotation of the shaft 15 transmits power to the second gear 17 through the mutual cooperation between the bevel teeth 18. The first gear 13 is meshed with the second gear 17 to drive the first gear 13 to rotate. The rotation of the first gear 13 will drive the spiral blade 11 to rotate through the rotating shaft 12, driving the paper dust that meets water to move downward along the axis of the rotating shaft 12 to the collection component. At the same time, the rotation of the spiral blade 11 will generate a centrifugal force on the paper dust that meets water, so that the excess water will flow into the dust box 8 through the through hole 7 and flow out from the water outlet pipe, thereby achieving the purpose of facilitating collection. When the spiral blade 11 rotates, it will drive the paper dust that meets water to move downward, and then the paper dust that meets water will push on the connecting plate 22, and then the connecting plate 22 will move downward under pressure, and the spring 21 will be in a stretched state. When the unloading component unloads the paper dust that has met water on the connecting plate 22, the spring 21 will return to its original position. When the paper dust accumulates, the spiral blade 11 will continue to rotate and feed downward. When a certain amount is reached, the sensor 23 detects that the support column 20 has moved to a suitable position, and then the second motor 24 is started. The second motor 24 will drive the processing plate 25 to rotate through the transmission shaft 26 to clean up the paper dust that has met water on the connecting plate 22, and then the support column 20 will reset under the action of the spring 21. When the through hole 7 opened on the housing 4 is blocked, the electric push rod is started at this time, and the electric push rod will drive the brush 28 fixedly connected to its output end to brush back and forth, so as to achieve the purpose of cleaning the housing 4 and cleaning the blocked through hole 7, thereby improving the working efficiency of the device. The reason why the radius of the second gear 17 is set to be smaller than the radius of the first gear 13 is that the transmission ratio is relatively large, which can reduce the speed loss in the transmission process, thereby improving the transmission efficiency. At the same time, the speed of the large gear is slower than that of the small gear, which is also conducive to maintaining the operation stability and accuracy of the transmission system. Because dust easily adheres to the surface of the drainage plate 5 after meeting water, thereby forming accumulation and affecting the working efficiency of the device, the smooth layer 29 can reduce the probability of dust adhering to the surface of the drainage plate 5 after meeting water, thereby improving the working efficiency of the device.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
