Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of color sorters, and in particular to a heat dissipation device for a sorting chamber box of a color sorter. Background Art

[0002] A color sorter distinguishes good and bad material particles based on their color and rejects inferior ones. It primarily consists of a feeder, a sorting chamber, a receiving device, a pneumatic system, and an electronic control system. The sorting chamber houses many of the machine's key components, including numerous electrical components. Heat dissipation and cooling are essential to prevent temperature rises from causing drift in the signals collected by the photoelectric sensor system, potentially affecting the machine's recognition capabilities.

[0003] The existing Chinese invention patent with publication number CN108449925A discloses a heat dissipation device for the sorting chamber of a color sorter. The invention presses the pressure rod up and down, causing the roller to drive the brush to clean the filter, making the cooling effect more significant. The refrigeration is cooled by the refrigeration unit, making the refrigeration pipe cooler, thereby turning the incoming air into cold air, which is used to cool and dissipate heat inside the sorting chamber.

[0004] However, the above device still has the following shortcomings. In this device, the refrigerator is arranged in the box, and the heat generated by the refrigeration work is also discharged into the box, resulting in a reduction in the cooling effect inside the box, and the cold air generated will directly blow the color sorting box to cool it down, causing the temperature of the side of the color sorting box close to the refrigerator to be lower, and the temperature of the side away from the refrigerator to be higher, making the overall cooling temperature of the color sorting box uneven. In addition, the side of the color sorting box close to the refrigerator will produce some condensed water mist due to the lower temperature. In addition, the device drives the rolling brush to perform cleaning work by pressing, and the bristles rolling along the surface of the filter will push the dust adhered to the surface of the filter into the mesh, further aggravating the clogging of the filter, resulting in poor air circulation, affecting the cooling effect of the device, and during the cleaning process, dust will escape when it falls off the surface of the filter, and the dust will adhere to the surfaces of other components.

[0042] The top of the sorting box body 1 is fixedly plugged with exhaust parts 3 distributed at equal distances. The exhaust parts 3 include an exhaust pipe 31 plugged into the sorting box body 1.

The air guide nozzle 32 corresponds to the installation position of the camera one by one. The increase of cold air in the body 1 causes the pressure to rise, and the airflow pushes the blocking block 33 to move upward along the exhaust pipe until the air guide cavity 34 is connected to the air guide nozzle 32, and the cold air is discharged from the air guide nozzle 32 until the pressure in the sorting box body 1 drops, wherein the opposite force between the magnetic blocks 37 drives the blocking block 33 to reset until the air pressure in the sorting box body 1 increases to repeatedly lift the blocking block 33, and perform precise blowing on the local surface of the transparent window corresponding to the camera, which can dry the outer surface of the transparent window when the temperature of the sorting box body 1 is low to avoid water vapor condensation affecting the camera image acquisition. In addition, during the intermittent blowing process, the dust that falls on the transparent window during the sorting work can be blown away, thereby improving the cleanliness of the transparent window.

[0043] The specific working method is: the air intake grille 11 introduces external air into the side box 2 when the air intake fan 20 is turned on, and the filter 9 at the bottom of the slide 8 filters the air entering the side box 2, so that the dust is concentrated on the outer wall of the bottom of the filter 9; the air is output from the air inlet 18 to the refrigeration mechanism 17 between the vertical plate 6 and the right-angle plate 5 channel through the air intake fan 20; the semiconductor cooling plate 171 introduces the heat on one side of the heat spreader 172 into the liquid cooling plate 173, and the heat exchange plate 174 connected to the heat spreader 172 and the strip groove 175 on the heat exchange plate 174 increase the exchange with the air. The staggered heat exchanger plates 174 absorb the heat of the air passing through the right-angle plate 5 and the vertical plate 6 and form cold air, wherein the heat exchange liquid in the liquid cooling plate 173 absorbs the heat generated by the semiconductor refrigeration plate 171, and the heated heat exchange liquid moves from the return pipe group to the heat exchanger 221, and the heat exchange solution flowing into the heat exchanger 221 is cooled by the heat sink 222 and the heat dissipation fan 223. The cooled heat exchange liquid re-enters the liquid cooling plate 173 from the circulation pump and the guide pipe group to continuously cool the semiconductor refrigeration plate 171.

[0044] The air duct 41 guides the cold air generated by the side box 2 into the sorting box body 1, wherein the triangular bar 43 uses two right-angled sides and the side block 44 to divert the cold air derived from the side port 42 to both sides, so that the cold air moves along the inner wall of the sorting box body 1 in a wrapped manner, avoiding the cold air from blowing directly on the camera and the transparent window, and preventing the camera lens and the outer surface of the transparent window from generating condensed water mist. Due to the increase of the cold air in the sorting box body 1 causing the pressure to rise, the airflow pushes the blocking block 33 to move upward along the exhaust pipe until the air guide cavity 34 is connected to the air guide nozzle 32, and the cold air The air is discharged from the air guide nozzle 32 until the pressure in the sorting box 1 drops, and the opposing forces between the magnetic blocks 37 drive the blocking block 33 to reset, until the air pressure in the sorting box 1 increases to repeatedly lift the blocking block 33, and perform precise blowing on the local surface of the transparent window corresponding to the camera. When the temperature of the sorting box 1 is low, the outer surface of the transparent window can be dried to prevent water vapor condensation from affecting the camera image acquisition. In addition, during the intermittent blowing process, the dust that falls on the transparent window during the sorting work can be blown away, thereby improving the cleanliness of the transparent window.

[0045] When the filter screen 9 needs to be cleaned, it is only necessary to push the horizontal bar 104 to drive the brush bar 105 and the two sliding sleeves 103 to slide in one direction along the sliding bar 101, wherein the bristles 106 at the bottom of the brush bar 105 slide along the top surface of the filter screen 9 to promote the dust adhering to the bottom of the filter screen 9 to fall off, and when the sliding sleeve 103 slides on the sliding bar 101, the tooth block 102 cooperates with the guiding effect of the inclined block 108 to realize that the sliding sleeve 103 presents a continuous up and down bumping action during the sliding process. When the sliding sleeve 103 moves upward, the bottom end of the bristles 106 will instantly break away from the filter screen 9 due to the delayed reset effect of the spring 1072, and then the spring 1072 drives the guide rod 1071 to drive The bristles 106 move downward until they collide with the top of the filter 9. Repeat the above action to achieve the purpose of high-frequency collision of the bristles 106 on the filter 9, further shaking off the dust adhering to the mesh of the filter 9, and the dust falls downward into the collection box 13. When the brush bar 106 moves to one end of the filter 9, you only need to pull the horizontal bar 104 upward until the inclined block 108 disengages from the tooth block 102, and then move the horizontal bar 104 and the brush bar 106 to the initial cleaning end of the filter 9 and release them, and continue to push the horizontal bar 104 to complete the repeated vibration cleaning work, and then perform the cleaning work when the door is opened. Cleaning from the back of the filter 9 is cleaner and more effective, and also prevents dust from escaping.
