[0012] This invention provides a multi-channel negative pressure dust removal device and an X-ray sorting machine. Compared with the prior art, it has the following advantages:

[0013] This utility model device adopts a multi-channel design with several fixed connecting pipes and a mixture inlet pipe. Compared with a single inlet pipe structure, it can simultaneously connect to multiple exhaust points of the previous process box, realize the synchronous and centralized collection of dust-containing gas, and avoid local gas stagnation. With the stable negative pressure generated by the negative pressure fan, it ensures that the airflow flows in a directional manner along the preset channel, and there is no leakage or backflow during the introduction process. The collection efficiency is improved compared with the traditional natural flow method. This invention uses a synchronous adjustment component consisting of a drive motor, a double-sided rack and pinion plate, and adjusting gears to drive all filter cartridges to rotate synchronously, achieving flexible switching between "static filtration" and "dynamic filtration": when the dust concentration is low, static filtration can meet the requirements with lower energy consumption; when the dust concentration is high or the filtration efficiency decreases, dynamic adjustment is activated, and the rotation of the filter cartridges can not only clean the dust attached to the orifices, but also increase the contact area and relative velocity between the gas and the filter surface, which can greatly improve its dust removal efficiency.

[0017] To address the technical problems in the background section, a multi-channel negative pressure dust removal device is provided as follows: Combination Figure 1-3 As shown, this utility model provides a multi-channel negative pressure dust removal device, including a dust collection box 1, a conical feeding cylinder 2 with a mating cylinder 3 fixedly connected through the bottom surface, and an installation valve installed on the mating cylinder 3.

A mounting bracket 19 is fixedly installed between the connecting cylinder 6 and the negative pressure chamber 5. A negative pressure fan 20 is installed on the mounting bracket 19. A dust collection adjustment mechanism is provided on the dust collector 1, and the dust collection adjustment mechanism is connected to the negative pressure chamber 5.

[0018] The connecting component includes a mixture inlet pipe 9, which is located on one side of the second flange 10. A first flange 8 is fixedly installed on the mixture inlet pipe 9. A plurality of mounting bolts 4 are evenly arranged between the first flange 8 and the second flange 10 and are connected by the plurality of mounting bolts 4.

[0019] The dust removal adjustment mechanism includes several elongated cylinders 13, each of which is rotatably mounted on the dust removal box 1. Each elongated cylinder 13 is fixedly mounted with a filter cylinder 17 on the portion inside the dust removal box 1, and each filter cylinder 17 is connected to the corresponding elongated cylinder 13. The right end of each filter cylinder 17 is located inside the negative pressure box 5 and is connected to the negative pressure box 5. Several fixing blocks 14 are fixedly provided on the left side of the dust collector 1. A double-sided rack plate 15 is slidably provided between two adjacent fixing blocks 14. Several adjusting gears 12 are meshed on both sides of each double-sided rack plate 15. Each adjusting gear 12 is fixedly sleeved on the corresponding elongated cylinder 13. A synchronous adjusting component 16 is provided between the two double-sided rack plates 15 and the dust collector 1.

[0020] Each filter cartridge 17 has several conical filter holes 18 evenly distributed throughout it.

[0021] The synchronous adjustment component 16 includes a mounting plate 164 and an adjustment plate 161. The mounting plate 164 is fixedly mounted on the dust collection box 1. A drive motor 165 is fixedly mounted through the mounting plate 164. A turntable 162 is fixedly mounted on the power output end of the drive motor 165. An eccentric shaft 163 is fixedly mounted on the turntable 162. Each double-sided rack plate 15 is fixedly connected to the adjustment plate 161. An elliptical sliding hole is opened through the adjustment plate 161, and the eccentric shaft 163 is located in the elliptical sliding hole.

[0022] Working principle: The core power source of the device is the negative pressure fan 20 inside the negative pressure box 5. Before operation, two key connections need to be completed: First, by bolting the first flange 8 and the second flange 10 of several mixture inlet pipes 9, all inlet pipes are connected to the exhaust port of the previous process box to achieve multi-channel gas introduction; Second, by connecting the device to the next process box through the mounting flange 7 at the end of the connecting cylinder 6, a closed-loop airflow channel is formed. After the negative pressure fan 20 is started, its operation will generate a continuous negative pressure in the negative pressure box 5. This negative pressure is transmitted to the dust collection box 1 through the filter cylinder 17 of the dust removal adjustment mechanism, so that a pressure difference is formed between the dust collection box 1 and the previous process box, thereby driving the dust-laden gas generated in the previous process box to flow into the dust collection box 1 simultaneously along multiple mixture inlet pipes 9, completing the centralized collection and introduction of dust-laden gas. After the dust-laden gas enters the dust collector 1, it will naturally flow to the filter cylinder 17 connected to the negative pressure chamber 5 (because the right end of the filter cylinder 17 extends directly into the negative pressure chamber 5, forming the only outlet for airflow). Each filter cylinder 17 is fixed through to the elongated cylinder 13, and several conical filter holes 18 are evenly opened on the cylinder wall. This conical structure design has the dual functions of "conduction" and "interception": the gas can flow to the negative pressure chamber 5 through the through hole structure of the conical filter hole 18, and then enter the next process chamber through the connecting cylinder 6; while the dust particles entrained in the gas, because the particle size is larger than the aperture of the conical filter hole 18, are intercepted on the outer wall or in the channel of the filter cylinder 17 and cannot pass through with the airflow, thereby achieving efficient separation of gas and dust. At the same time, the conical feeding cylinder 2 at the bottom of the dust collector 1 will receive the dust that falls after being intercepted. With the help of the installation valve on the cylinder 3, the feeding time can be controlled to avoid dust accumulation in the dust collector 1. When the dust-laden gas concentration is high and static filtration alone cannot meet the dust removal requirements, the filtration efficiency is actively improved through the synchronous adjustment component 16. The working logic of the synchronous adjustment component 16 is as follows: The drive motor 165 on the mounting plate 164 is started, and its power output drives the turntable 162 to rotate. The eccentric shaft 163 on the turntable 162 then performs circular motion. Since the eccentric shaft 163 is embedded in the elliptical sliding hole of the adjustment plate 161, the circular motion is converted into a sliding thrust along the elliptical sliding hole, driving the adjustment plate 161 to perform reciprocating linear motion. The adjustment plate 161 is fixedly connected to two double-sided rack plates 15, thereby driving the double-sided rack plates 15 to move in a reciprocating linear motion. The slides synchronously back and forth within the through-track between adjacent fixed blocks 14; both sides of the double-sided rack plate 15 are engaged with several adjusting gears 12, and the adjusting gears 12 are fixedly sleeved on the elongated cylinder 13. Therefore, the sliding of the rack plate will drive all the adjusting gears 12 to rotate synchronously, and finally drive the filter cylinder 17, which is fixedly connected to the elongated cylinder 13, to rotate in the dust collection box 1. The rotation of the filter cylinder 17 changes its contact angle and relative flow velocity with the dust-laden gas. On the one hand, it avoids the blockage caused by local accumulation of dust on the surface of the conical filter hole 18, and on the other hand, it increases the frequency of contact between the gas and the filter hole, thereby significantly improving the efficiency and stability of filtration and dust removal.
