Description

Technical Field

[0001] This utility model relates to the field of dust filtration technology, specifically a dual-duct dust separation and filtration device. Background Technology

[0002] Metal scrap refers to metallic materials that have lost their economic value or cannot be reused during the production process. This metal scrap may originate from manufacturing, construction, automobile dismantling, and the processing of other scrap metal products, and the types of scrap metal are diverse. Recycling and reusing metal scrap can reduce dependence on natural resources, reduce energy consumption and emissions, mitigate the environmental impact of producing new metals, and also help save costs.

[0003] When recycling metal scrap, the scrap is usually put into metal scrap recycling equipment, where the internal filtration system separates and filters out dust particles. The scrap with the dust particles removed is then discharged into a transfer vehicle for transfer to subsequent processes.

[0004] When metal scrap accumulates inside the metal scrap recycling equipment, the metal scrap blocks each other from contacting, causing some dust particles or debris to be blocked and difficult to be effectively filtered and discharged. Utility Model Content

[0005] The purpose of this invention is to provide a dual-duct dust separation and filtration device, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A dual-duct dust separation and filtration device includes a metal scrap recycling equipment body. A feeding port and an exhaust section are located on one side of the top of the metal scrap recycling equipment body. A conveying pipe and a waste collection section are sequentially arranged below the feeding port within the metal scrap recycling equipment body. The feeding port, conveying pipe, and waste collection section are connected sequentially from top to bottom. A filter chamber with its top communicating with the exhaust section is located below the exhaust section within the metal scrap recycling equipment body. The device also includes a pair of filter cylinders, an air guiding mechanism, a first guide pipe, and a second guide pipe. The two filter cylinders are symmetrically arranged within the filter chamber, and the air guiding mechanism is located within the filter chamber. Above the two filter cylinders, a first guide pipe and a second guide pipe are used to vertically transport the air in the filter chamber upwards and discharge it to the outside of the metal waste recycling equipment body through the exhaust section. Both the first guide pipe and the second guide pipe are located inside the metal waste recycling equipment body. One end of the first guide pipe is connected to the bottom of the conveying pipe side, and the other end extends into the filter chamber and is connected to the inlet port of one of the filter cylinders. One end of the second guide pipe is connected to the top of the conveying pipe side, and the other end extends into the filter chamber and is connected to the inlet port of the other filter cylinder. The first guide pipe and the second guide pipe can guide the air individually or simultaneously.

[0008] Therefore, when the second guide pipe operates alone, an airflow is formed sequentially through the conveying pipe, the second guide pipe, and the filter chamber. This airflow can draw some of the metal scrap upwards from the conveying pipe, causing it to tumble and thus reducing obstruction of dust particles and debris, thereby improving the filtration effect. When the scrap falls into the scrap collection section, since dust particles and debris still remain in the conveying pipe, the simultaneous operation of the first and second guide pipes draws the dust particles and debris from both the upper and lower parts of the conveying pipe into the filter cartridge, maximizing the filtration effect.

[0009] Furthermore, a first electric valve is installed on the first guide pipe, and a second electric valve is installed on the second guide pipe.

[0010] Furthermore, intercepting nets are installed in both the first diversion pipe near the delivery pipe and the second diversion pipe near the delivery pipe.

[0011] Furthermore, the air guiding mechanism includes a first mounting frame, a support column, a second mounting frame, an air induced impeller, and a drive motor. The first mounting frame is installed inside the filter chamber, and the second mounting frame is installed above the first mounting frame via the support column. The air induced impeller is rotatably installed between the second mounting frame and the first mounting frame. The first mounting frame has a through air inlet at a position corresponding to the position of the air induced impeller. The drive motor is fixedly installed on the second mounting frame, and its output shaft is fixedly connected to the shaft end of the air induced impeller.

[0012] Furthermore, the side of the metal scrap recycling equipment body is provided with maintenance ports that communicate with the filter chamber at the positions corresponding to the two filter cylinders. Two cover plates are detachably installed on the side of the metal scrap recycling equipment body to seal the maintenance ports respectively.

[0013] Furthermore, a filter screen is installed inside the exhaust section.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. When the present invention operates by guiding the flow through the second guide pipe alone, an airflow is formed by passing through the conveying pipe, the second guide pipe and the filter chamber in sequence. This airflow can attract some of the metal waste in the conveying pipe upward, causing the metal waste to tumble in the conveying pipe, thereby reducing the obstruction of dust particles and dust and improving the filtration effect of dust particles and dust.

[0016] 2. When waste falls into the waste collection section, since dust particles and debris still exist in the conveying pipe, the first and second guide pipes work simultaneously to draw the dust particles and debris from the conveying pipe into the filter cartridge from both the upper and lower parts, thereby maximizing the filtration effect of dust particles and debris.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Please see Figures 1-4 This utility model provides a dual-duct dust separation and filtration device, including a metal waste recycling equipment body 1. The metal waste recycling equipment body 1 has a feeding port 11 and an exhaust section 15 on one side of its top. Inside the metal waste recycling equipment body 1, below the feeding port 11, a conveying pipe 12 and a waste collection section 13 are sequentially arranged. The feeding port 11, conveying pipe 12, and waste collection section 13 are connected sequentially from top to bottom. Inside the metal waste recycling equipment body 1, below the exhaust section 15, is a filter chamber 14 whose top communicates with the exhaust section 15. It also includes a pair of filter cylinders 2, an air guiding mechanism 3, a first guide pipe 4, and a second guide pipe 5. The two filter cylinders 2 are symmetrically arranged inside the filter chamber 14. 3 is located inside the filter chamber 14 and above the two filter cylinders 2. It is used to vertically transport the air inside the filter chamber 14 upward and discharge it to the outside of the metal waste recycling equipment body 1 through the exhaust section 15. The first guide pipe 4 and the second guide pipe 5 are both located inside the metal waste recycling equipment body 1. One end of the first guide pipe 4 is connected to the bottom side of the conveying pipe 12, and the other end extends into the filter chamber 14 and is connected to the inlet port of one of the filter cylinders 2. One end of the second guide pipe 5 is connected to the top side of the conveying pipe 12, and the other end extends into the filter chamber 14 and is connected to the inlet port of the other filter cylinder 2. The first guide pipe 4 and the second guide pipe 5 can guide the air individually or simultaneously.

[0026] When recycling metal scrap, the scrap is fed into the conveying pipe 12 through the inlet 11. The air guide mechanism 3 creates an upward airflow within the filter chamber 14. When the second guide pipe 5 is used for independent airflow guidance, the airflow sequentially passes through the conveying pipe 12, the second guide pipe 5, and the filter chamber 14, forming a single airflow that draws some of the metal scrap upwards from the conveying pipe 12. This causes the scrap to tumble within the conveying pipe 12, reducing the obstruction of dust particles and debris. The dust particles and debris are then drawn into one of the filter cartridges 2 through the second guide pipe 5 for filtration. The airflow is guided by the first guide pipe 4 alone, passing through the conveying pipe 12, the first guide pipe 4 and the filter chamber 14 in sequence to form an airflow. This airflow can attract the metal waste in the conveying pipe 12 downwards. Combined with the gravity of the waste, the waste falls into the waste collection section 13. When the waste falls into the waste collection section 13, since there are still dust particles and dust scattered in the conveying pipe 12, the first guide pipe 4 and the second guide pipe 5 work together to guide the airflow. The dust particles and dust in the conveying pipe 12 are sucked into the filter cylinder 2 from the upper and lower parts, so as to maximize the filtration effect of dust particles and dust.

[0027] Specifically, a first electric valve 41 is installed on the first guide pipe 4. By adjusting the first electric valve 41, the first guide pipe 4 can be opened and closed. A second electric valve 51 is installed on the second guide pipe 5. By adjusting the second electric valve 51, the second guide pipe 5 can be opened and closed.

[0028] Specifically, intercepting nets (not shown in the figure) are installed in the first guide pipe 4 near the conveying pipe 12 and in the second guide pipe 5 near the conveying pipe 12. By setting up the intercepting nets, metal waste can be prevented from being sucked into the first guide pipe 4 or the second guide pipe 5, thus preventing blockage or waste.

[0029] Specifically, the air guiding mechanism 3 includes a first mounting frame 31, a support column 32, a second mounting frame 33, an air-guiding impeller 34, and a drive motor 35. The first mounting frame 31 is installed inside the filter chamber 14. The second mounting frame 33 is installed above the first mounting frame 31 via the support column 32. The air-guiding impeller 34 is rotatably installed between the second mounting frame 33 and the first mounting frame 31. The first mounting frame 31 has a through air inlet 311 at a position corresponding to the air-guiding impeller 34. The drive motor 35 is fixedly installed on the second mounting frame 33, and its output shaft is fixedly connected to the shaft end of the air-guiding impeller 34. When the drive motor 35 works, its output shaft drives the air-guiding impeller 34 to rotate, thereby forming a vertically upward airflow in the filter chamber 14.

[0030] Specifically, the side of the metal scrap recycling equipment body 1 is provided with maintenance ports 21 that communicate with the filter chamber 14 at the corresponding positions of the two filter cylinders 2. Two cover plates 22 are detachably installed on the side of the metal scrap recycling equipment body 1 to seal the maintenance ports 21 respectively. By setting two maintenance ports 21 on the side of the metal scrap recycling equipment body 1, it is convenient to perform regular maintenance, replacement or repair of the two filter cylinders 2.

[0031] Specifically, the exhaust section 15 is equipped with a filter (not shown in the figure) to prevent dust particles in the outside air from entering the filter chamber 14 through the exhaust section 15 and causing pollution.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
