DETAILED DESCRIPTION

[0021] Since part of the alumina powder is in the pore structure on the surface of the alumina particles, and the adjacent alumina particles are in close contact with each other, the alumina powder in the pores of the alumina particles is prone to remain.

[0022] Therefore, the present application provides a white clay bed alumina powder cleaning device, which comprises a vibration mechanism 100 and a cleaning mechanism 200.

[0023] The structure and shape of the white clay bed alumina powder cleaning device provided by the present embodiment are described in detail as follows: Figures 1-8 The white clay bed alumina powder cleaning device provided by the present embodiment comprises a vibration mechanism 100 and a cleaning mechanism 200. The vibration mechanism 100 comprises a vibration rod 110 and a bearing frame 120, and the vibration rod 110 is installed on the bearing frame 120; the cleaning mechanism 200 comprises a dust removal structure 210; the vibration rod 110 is inserted into the alumina filler layer to drive the alumina particles to vibrate, so that the alumina dust on the surface of the alumina particles is stripped; the dust removal structure 210 drives air to flow out of the alumina filler layer, so that the stripped alumina powder is separated from the alumina filler layer.

[0024] In the present embodiment, the alumina filler layer is layered, and the vibration rod 110 inserted into the alumina filler layer drives the alumina particles to vibrate, so that the alumina particles collide with each other, and then the alumina dust on the surface of the alumina particles is stripped; at the same time, the dust removal structure 210 drives air to flow out of the alumina filler layer, so that the stripped alumina powder is separated from the alumina filler layer.

[0025] In addition, the vibration rod 110 inserted into the alumina filler layer drives the alumina particles to vibrate, so that the gaps between the alumina particles increase, and then the dust removal structure 210 drives the air to flow out of the alumina filler layer to provide a path, in which the air provides an upward thrust to the alumina particles to reduce the influence of gravity on the vibration of the alumina particles, thereby increasing the vibration area and amplitude of the alumina particles.

[0026] Regarding the shape and structure of the cleaning mechanism 200 in more detail: As shown in Figure 4 , the dust removal structure 210 includes an exhaust insertion pipe 211, a duct fan 212, a dust filter tank 213 and an air inlet pipe 214 which are sequentially communicated; the outlet of the exhaust insertion pipe 211 is located in the alumina filler layer; the inlet of the air inlet pipe 214 is directed towards and above the alumina filler layer; The duct fan 212 drives the air to flow through the air inlet pipe 214, the dust filter tank 213, the duct fan 212, the exhaust insertion pipe 211 and the alumina filler layer in sequence to form a circulation, and in this process, the dust filter tank 213 separates the alumina powder in the air.

[0027] In order to avoid the alumina particles entering the air inlet pipe 214: As shown in Figure 4 , the inlet of the air inlet pipe 214 is provided with a screen, and the screen size of the screen is smaller than the diameter of the alumina particles, which separates the alumina particles while ensuring that the alumina powder in the air enters the air inlet pipe 214.

[0028] In order to avoid the exhaust insertion pipe 211 driving the alumina powder to move to the deep part of the alumina filler layer: As shown in Figure 4 , the dust removal structure 210 further includes a separation guide nozzle 215; the inlet of the separation guide nozzle 215 is communicated with the outlet of the exhaust insertion pipe 211; the surface of the separation guide nozzle 215 is provided with a plurality of separation holes for air flow and to avoid the alumina particles entering the exhaust insertion pipe 211, while guiding the air to flow to the side of the air inlet pipe 214 inlet.

[0029] In order to realize the separation guide nozzle 215 guiding the air to flow to the side of the air inlet pipe 214 inlet: The outlets of the plurality of separation holes are inclined or vertically upward to guide the air output by the separation guide nozzle 215 to flow to the side of the air inlet pipe 214 inlet.

[0030] In order to separate the alumina powder in the air flowing through the dust filter tank 213: As shown in Figure 5As shown, the dust filter tank 213 includes a shell 201, a conical filter cover 202 and a powder discharge pipe 203; the conical filter cover 202 is installed in the shell 201, and is used to filter the aluminum oxide powder in the air and guide the aluminum oxide powder to move toward its flared end; the powder discharge pipe 203 is connected to the shell 201, and the inlet is located on one side of the flared end of the conical filter cover 202, and is used to discharge the aluminum oxide powder.

[0031] In order to prevent the alumina powder that has separated from the alumina filler layer from entering the air in the clay bed: like Figures 2-4 As shown, the cleaning mechanism 200 further includes an air collecting hood 220; the air collecting hood 220 is sleeved on the supporting frame 120; the inlet of the air inlet pipe 214 is connected to the outlet of the air collecting hood 220; The air collecting hood 220 is in contact with the alumina filler layer, and the air inputted from the separation guide nozzle 215 passes through the alumina filler layer and then enters the air collecting hood 220 .

[0032] In order to achieve that the gas collecting hood 220 abuts against the alumina filler layer: like Figure 8 As shown, the gas collecting hood 220 includes a conforming plate 221, two half-covers 222 and two elastic sealing strips 223; the conforming plate 221 is connected to the supporting frame 120; the two half-covers 222 are both installed on the conforming plate 221 to facilitate the disassembly and assembly of the gas collecting hood 220; the two elastic sealing strips 223 are respectively connected to the side of the two half-covers 222 away from the conforming plate 221, and the elastic sealing strips 223 seal the half-covers 222 and the alumina filler layer through elastic deformation.

[0033] In order to collect the aluminum oxide powder discharged from the powder discharge pipe 203: like Figures 2-3 As shown, the cleaning mechanism 200 further includes a dust storage box 230 ; the dust storage box 230 is detachably mounted on the gas collecting hood 220 ; the outlet of the powder discharge pipe 203 is communicated with the inlet of the dust storage box 230 .

[0034] In this embodiment, the vibration mechanism 100 is driven to move toward the alumina packing layer so that the vibration rod 110 and the exhaust tube 211 are inserted into the alumina packing layer. During this process, the separation guide nozzle 215 uses its own conical streamline structure to reduce the resistance borne by the exhaust tube 211 when inserted into the alumina packing layer, while preventing alumina particles from entering the exhaust tube 211 and being pinched. After the gas collecting hood 220 abuts against the alumina packing layer, the vibration mechanism 100 stops moving. At this time, the gas collecting hood 220 and the alumina packing layer form a dust removal chamber.

[0035] The air in the dust removal cavity driven by the pipeline fan 212 flows through the air inlet pipe 214, the dust filter tank 213, the pipeline fan 212 and the air outlet pipe 211 into the separation guide nozzle 215 in turn, and the air in the separation guide nozzle 215 flows to the air collecting cover 220 under the guidance of the separation hole. In this process, the alumina powder is separated from the alumina filler layer and enters the dust removal cavity, so that the alumina powder separated from the alumina filler layer does not enter the air in the white clay bed. At this time, the air forms a cycle between the inlet of the pipeline fan 212 and the outlet of the separation guide nozzle 215.

[0036] In this process, the air flowing through the dust filter tank 213 first enters the shell 201, and the air in the shell 201 passes through the conical filter cover 202 under the action of pressure. In this process, the conical filter cover 202 filters and separates the alumina powder in the air. The filtered and purified air is output from the shell 201. Since the conical end of the conical filter cover 202 faces the air input direction, the alumina powder on the surface of the conical filter cover 202 is moved to the flared end by the air. At the same time, the vibration rod 110 transmits vibration stress to the dust filter tank 213, so that the alumina powder stuck in the filter hole of the conical filter cover 202 is stripped and moved to the flared end, and the alumina powder at the flared end is driven to pass through the powder discharge pipe 203 into the dust storage box 230.

[0037] In the above operation process, the cleaning mechanism 200 drives the air in the white clay bed to pass through the alumina filler layer, so that the alumina powder is separated from the alumina filler layer. At the same time, the alumina powder separated from the alumina filler layer is filtered and collected by the dust filter tank 213 and the dust storage box 230, which avoids the entry of external substances into the white clay bed and reduces the probability of secondary pollution.

[0038] In order to improve the convenience of the alumina powder cleaning device in the operation process of the white clay bed: As shown in Figures 1-2 , the alumina powder cleaning device for the white clay bed further comprises a lifting lifting mechanism 300; the lifting lifting mechanism 300 is connected with the bearing frame 120 and is used to drive the bearing frame 120 to move along the vertical direction; the lifting lifting mechanism 300 comprises a lifting ring 310, and the lifting ring 310 is used for lifting.

[0039] In order to realize the movement of the bearing frame 120 along the vertical direction driven by the lifting lifting mechanism 300: As shown in Figure 7 , the lifting lifting mechanism 300 further comprises a lifting base 320, a lifting push rod 330 and a lifting frame 340; the lifting push rod 330 is installed on the lifting base 320, and the telescopic end is connected with the bearing frame 120; one end of the lifting frame 340 is connected with the lifting ring 310, and the other end is installed on the lifting base 320; the lifting push rod 330 drives the vibration mechanism 100 and the cleaning mechanism 200 to move along the vertical direction.

[0040] In order to facilitate the white clay bed alumina powder cleaning device to move in the white clay bed: As shown in Figure 7 The lifting mechanism 300 also includes a handle 350; the handle 350 is installed on the lifting frame 340, and is used to drive the lifting frame 340 to move.

[0041] In this embodiment, the lifting device lifts the device from the entrance of the white clay bed to the inside of the white clay bed through the lifting ring 310, and then the operator drives the device to move in the white clay bed through the handle 350. After the device moves to the starting point of the operation, the lifting push rod 330 drives the bearing frame 120 to move downward, so that the vibration rod 110 and the exhaust insertion pipe 211 are inserted into the alumina filler layer. The handle 350 drives the device to move along the alumina filler layer to clean the alumina powder in the alumina filler layer. During this process, the device is always in a lifting state to reduce the influence of gravity on the movement of the device.

[0042] The vibration rod 110 inserted into the alumina filler layer drives the alumina particles to vibrate, and at the same time the exhaust insertion pipe 211 injects air into the alumina filler layer from bottom to top through the partition guide nozzle 215. Under the combined action of the two, the alumina particles in the operation area of the device are in a liquefied flow state, so as to reduce the resistance of the vibration rod 110 and the exhaust insertion pipe 211 moving in the alumina filler layer.

[0043] In order to improve the flatness of the alumina filler layer: As shown in Figure 6 The vibration mechanism 100 also includes a flattening plate 130; the flattening plate 130 is installed on the bearing frame 120 and is sleeved on the vibration rod 110, and is used to flatten the alumina filler layer. The flattening plate 130 is sleeved on the exhaust insertion pipe 211, and is used to drive the exhaust insertion pipe 211 to vibrate synchronously.

[0044] In order to avoid deformation of the exhaust insertion pipe 211: As shown in Figure 6 The vibration mechanism 100 also includes a reinforcing support 140; the vibration rod 110 and the exhaust insertion pipe 211 are inserted into the reinforcing support 140, and are used to drive the exhaust insertion pipe 211 to vibrate synchronously.

[0045] In this embodiment, the gas collecting cover 220 and the flattening plate 130 move synchronously to the alumina filler layer. After the flattening plate 130 abuts against the alumina filler layer, the elastic sealing strip 223 elastically abuts against the alumina filler layer through elastic deformation, thereby reducing the stress borne by the gas collecting cover 220 and reducing the probability of deformation failure of the gas collecting cover 220.

[0046] The vibration rod 110 drives the flattening plate 130 to vibrate, and the vibrating flattening plate 130 flattens the surface of the moving aluminum oxide filler layer, while the flattening plate 130 and the reinforcing support 140 synchronously drive the exhaust insertion pipe 211 to vibrate, so as to reduce the resistance of the exhaust insertion pipe 211 moving in the aluminum oxide filler layer, and the flattening plate 130 and the reinforcing support 140 are sleeved on both ends of the exhaust insertion pipe 211, so as to reduce the probability of deformation failure of the exhaust insertion pipe 211.

[0047] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
