[0031] See also Figures 1 to 10 , the present invention provides a technical solution: a powder selection machine feeding and conveying device, characterized in that: it includes a shell 1, the upper end of the shell 1 is fixedly connected with a docking pipe 2, the inner end of the docking pipe 2 is flange-connected with an inner docking pipe 5, the lower end of the inner docking pipe 5 is fixedly connected with an air suction pump 22, and the lower end of the air suction pump 22 is fixedly connected with a feed dispersion port 7; a rotating sleeve 12, the inner end of the rotating sleeve 12 is fixedly connected with a conveying blade 6, the inner end of the conveying blade 6 is fixedly connected with an outer filter air-permeable sleeve 15, and the outer side of the outer filter air-permeable sleeve 15 is provided with a plurality of air holes 21; an inner condensing sleeve 8, the inner sleeve of the inner condensing sleeve 8 is provided with a cooling device, and the outer side of the inner condensing sleeve 8 is provided with a recoil device; the cooling device includes a condensing pipe interface 4, the inner end of the condensing pipe interface 4 is fixedly connected with a cooling device A condensate pumping circulation pump 10 is provided, and the output end of the condensate pumping circulation pump 10 is connected in a closed loop with a condenser pipe 9, and an insulating sleeve 11 is provided between the condenser pipes 9; the recoil device comprises a support frame 16, and a plurality of stamping springs 17 are fixedly connected to the lower end of the support frame 16 in a circular array, and an elastic support plate 18 is fixedly connected to the end of the stamping spring 17, and two support rods 19 are fixedly connected to the lower end surface of the elastic support plate 18, and an inclined bracket 20 is supported and connected at the lower end of the support rod 19, and the inclined bracket 20 is fixedly connected to the outer side of the inner condenser pipe 8, and the docking pipe 2 can be connected to the end of the powder selector through a flange. After the powder selector selects the powder, the dust can be sucked into the inner docking pipe 5 under the action of the suction pump 22, and the dust can be prevented from accumulating at the outlet of the powder selector, so as to realize stable transportation.

[0032] The outer side of the inner docking pipe 5 is fixedly connected to a limited mounting bracket 14, the inner side of the limited mounting bracket 14 is fixedly connected to a power bevel gear assembly 13, the output end gear of the power bevel gear assembly 13 is connected to the inner side of the rotating sleeve 12, the rotating sleeve 12 is sealingly rotatably connected to the outer side of the limited mounting bracket 14, and the upper end of the limited mounting bracket 14 is fixedly connected to a sealing sleeve 23. The power bevel gear assembly 13 can drive the rotating sleeve 12 to rotate stably in the outer casing 1 through gear transmission, and is sealed with the limited mounting bracket 14 to prevent dust from circulating in the limited mounting bracket 14.

[0033] The air holes 21 are arranged in a circular array on the outer filter air-permeable sleeve 15, and the support frame 16 is fixedly connected to the inner side of the outer filter air-permeable sleeve 15. Each circle of the air holes 21 is between the elastic support plate 18 and the inclined support 20. The upper end surface of the inclined support 20 is two centrally symmetrical inclined surfaces. The support rods 19 are one long and one short, and the ends of the support rods 19 are correspondingly supported on the upper end surface of the inclined support 20. The rear end of the housing 1 is fixedly connected with an outlet docking flange 3. When the rotating sleeve 12 rotates, the conveying blades 6 are driven to rotate to realize the transportation of dust, and at the same time drive the outer filter The air sleeve 15 rotates, so that the elastic support plate 18 and the inclined bracket 20 can rotate relative to each other. Under the support of the support rod 19, the stamping spring 17 is compressed, and part of the air outside the outer filter air sleeve 15 is sucked in. When the support rod 19 passes through the highest point of the inclined bracket 20, under the action of the stamping spring 17, the elastic support plate 18 recoils rapidly, and a high-pressure area is formed in the inclined bracket 20 and the elastic support plate 18, so that the air hole 21 can be recoiled to prevent dust from clogging the air hole 21. By repeating this process, air suction and anti-clogging can be achieved.

[0034] The outer side of the condenser 9 is threaded, and the inner reflux is a straight tube, which is inserted into the inner side of the threaded condenser 9. The outer side of the straight tube is provided with an insulating sleeve 11, and the inner condenser sleeve 8 is provided inside the outer filter breathable sleeve 15. The docking entrance of the condenser interface 4 is arranged on the outside of the outer shell 1. The condenser 9 can reduce the internal temperature to prevent some accidents caused by excessive temperature. At the same time, due to the large temperature difference near the inner condenser sleeve 8, condensed water vapor is more likely to appear, which has a certain impact on the quality of the dust. When the recoil device inhales air, it can absorb air and condense between the inner condenser sleeve 8 and the outer filter breathable sleeve 15, that is, humid and high-temperature gas is inhaled between the inner condenser sleeve 8 and the outer filter breathable sleeve 15, and at the same time, a certain amount of dust is blocked, so that the humid gas condenses water in the inner condenser 8 and sprays out dry and low-temperature gas, thereby achieving cooling and dehumidification, and effectively preventing the condensed liquid moisture from combining with dust to affect the dust quality.

[0035] In actual use, the docking pipe 2 can be connected to the end of the powder selector through a flange. After the powder selector selects the powder, the dust can be sucked into the inner docking pipe 5 under the action of the suction pump 22, and the dust can be prevented from accumulating at the outlet of the powder selector to achieve stable transportation. The power bevel gear assembly 13 can drive the rotating sleeve 12 to rotate stably in the outer shell 1 through gear transmission, and it is sealed with the limit mounting bracket 14 to prevent dust from circulating in the limit mounting bracket 14. When the rotating sleeve 12 rotates, it drives the conveying blades 6 to rotate to achieve dust transportation, and at the same time drives the outer filter air sleeve 15 to rotate, so that the elastic support plate 18 and the inclined bracket 20 can achieve relative rotation. Under the support of the support rod 19, the stamping spring 17 is compressed to inhale part of the air outside the outer filter air sleeve 15. When the support rod 19 passes through the highest point of the inclined bracket 20, the stamping spring 17 is pressed. Under the action, the elastic support plate 18 recoils rapidly, and a high-pressure area is formed in the inclined bracket 20 and the elastic support plate 18, so that the air hole 21 can be recoiled to prevent dust from clogging the air hole 21. By repeating this process, air suction and anti-clogging can be achieved. The condenser 9 can reduce the internal temperature to prevent some accidents caused by excessive temperature. At the same time, due to the large temperature difference near the inner condensation sleeve 8, condensed water vapor is more likely to appear, which has a certain impact on the quality of the dust. When the recoil device inhales air, it can absorb air and condense between the inner condensation sleeve 8 and the outer filter breathable sleeve 15, that is, humid and high-temperature gas is inhaled between the inner condensation sleeve 8 and the outer filter breathable sleeve 15, and at the same time, a certain amount of dust is blocked, so that the humid gas condenses water in the inner condenser tube 8, and sprays dry and low-temperature gas, thereby achieving cooling and dehumidification, and effectively preventing the condensed liquid moisture from combining with dust to affect the dust quality.
