Description

Technical Field

[0001] This utility model belongs to the field of air sorting equipment, specifically, it relates to an air sorting device with a pulse dispersing device. Background Technology

[0002] In the field of solid waste recycling and treatment, air separation is widely used in the treatment and recycling of municipal solid waste, fibrous solid waste, agricultural rice and wheat, and other wastes. Air separation is a device that uses the difference in suspension velocity between light and heavy materials to separate materials using airflow. Air separation can separate light and heavy materials, reducing the processing pressure of subsequent processing steps.

[0003] However, in actual use, we found that there are many mismatches between the light and heavy material outlets of the air sorting system. A significant reason for this is that the existing feeding devices cannot effectively break up the materials before they enter the air sorting process. When materials are piled up, mutually adsorbed, and wrapped, the sorting effect is not as expected, and the outlet materials are mixed. Moreover, most existing common material breaking devices rely on vibrating feeders to shake and feed the materials, which causes a large amount of dust to escape, resulting in a harsh on-site environment and serious dust pollution.

[0030] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0031] like Figure 1-3 As shown, an air separation device with a pulse dispersing mechanism includes: a Z-type air separator 7, with a feed inlet 1 at the top of the Z-type air separator 7, a fan 2 installed inside the feed inlet 1, and a pulse valve assembly 3 for dispersing materials on the side of the Z-type air separator 7. The pulse valve assembly 3 is connected to the interior of the Z-type air separator 7 and is located below the fan 2. An air separation inlet 13 is located on the lower side of one side of the Z-type air separator 7, and the air separation inlet 13 is connected to the outlet of a centrifugal fan 10.

[0032] This utility model discloses an air separation device with a pulse dispersing device. The outlet of the centrifugal fan 10 is connected to the air separation inlet 13 to provide airflow for air separation. During separation, when the mixture of light and heavy materials is fed into the separation channel of the Z-type air separator 7 through the feed inlet 1, it first enters the shut-off fan 2. The shut-off fan 2 can be a commercially available shut-off fan, which plays the role of locking the airflow and initially dispersing the materials to prevent the materials from escaping and causing dust pollution on site. After the materials are discharged from the outlet of the shut-off fan 2, they enter the separation channel of the Z-type air separator 7. A pulse valve group 3 for dispersing materials is provided on the side of the Z-type air separator 7. The pulse valve group 3 is connected to the inside of the Z-type air separator 7, thereby performing pulse dispersing treatment on the materials entering the separation channel of the Z-type air separator 7, effectively dispersing the mixture of light and heavy materials, which is conducive to improving the separation accuracy of the air separation equipment and improving the separation effect.

[0033] The air classifier inlet 13 has a fan-shaped structure. The diameter of the end of the air classifier inlet 13 connected to the centrifugal fan 10 is smaller than the diameter of the end of the air classifier inlet 13 furthest from the centrifugal fan 10.

[0034] The air inlet 13 adopts a fan-shaped structure with a small connection port diameter and a large distance port diameter, which helps to fully disperse the material in the initial stage of air separation, creating favorable conditions for subsequent air separation.

[0035] From the connection end to the end away from the centrifugal fan 10, the diameter of the air classifier inlet 13 gradually increases. During this process, the airflow gradually slows down and diffuses evenly, which can cover the air classifier area more widely, so that the material is affected by the airflow over a larger range. This avoids situations where the local airflow is too strong or too weak, ensuring the stability and consistency of the air classifier process. The fan-shaped structure design helps to guide the airflow smoothly into the air classifier, reducing the possibility of the airflow forming vortices at the air inlet, reducing airflow energy loss, and allowing the airflow to flow more smoothly, thereby improving energy utilization efficiency.

[0036] The bottom of the Z-type air classifier 7 is equipped with a heavy material outlet 8, which is connected to the feed inlet 1 through the internal separation channel of the Z-type air classifier 7. The heavy material sinks naturally due to gravity and is discharged through the heavy material outlet 8 into downstream equipment or collected.

[0037] A light material outlet 9 is located on the upper side of one side of the Z-type air separator 7. The light material outlet 9 and the air separation inlet 13 are located on the same side of the Z-type air separator 7. The light material outlet 9 is connected to the feed inlet 1 through the internal separation channel of the Z-type air separator 7. Driven by the airflow provided by the centrifugal fan 10, the light material enters the cyclone collector 11 through the pipe. The fact that the light material outlet 9 and the air separation inlet 13 are located on the same side of the Z-type air separator 7 allows the airflow introduced by the air separation inlet 13 to form a relatively simple and smooth flow path inside the Z-type air separator 7. The airflow can carry the light material to the light material outlet 9 more directly, reducing the detour and turbulence of the airflow inside the machine, reducing airflow energy loss, and improving the airflow's carrying capacity for light materials. This allows the light material to reach the light material outlet 9 from the feed inlet 1 through the separation channel more quickly and efficiently, thereby improving the overall air separation process. The sorting efficiency is improved. Due to the optimization of the airflow path, light materials can be separated more accurately under the action of stable and directional airflow. Compared with the case of complex airflow path, the same-side arrangement reduces the possibility of light materials and heavy materials mixing again, improves the separation accuracy of light materials and heavy materials, and makes the purity of the light materials collected in the end higher. The same-side arrangement allows the pipes and connecting parts related to the light material outlet 9 and the air separation inlet 13 to be concentrated on one side of the Z-type air separator 7, which is conducive to the compact layout of the equipment and can reduce the equipment footprint. This is very important for production workshops with limited space and can effectively improve the space utilization of the workshop.

[0038] The light material outlet 9 is connected to the inlet of the cyclone collector 11 via a pipe; the diameter of the end of the light material outlet 9 connected to the Z-type air separator 7 is larger than the diameter of the end of the light material outlet 9 furthest from the Z-type air separator 7. The air inlet of the centrifugal fan 10 is connected to the air outlet of the cyclone collector 11. The centrifugal fan 10 is a variable frequency fan.

[0039] The light material outlet 9 adopts a structure with a large connection port diameter to the Z-type air separator 7 and a small connection port diameter further away. When the airflow carrying light materials enters the light material outlet 9 from the Z-type air separator 7, the airflow velocity will decrease due to the increased cross-sectional area, according to the principles of fluid mechanics. This acts as a buffer, reducing the impact of the airflow on the outlet, reducing equipment wear, and extending the service life of the light material outlet 9 and related connecting parts. The reduced airflow velocity allows the light materials to be carried more stably, reducing the flying and scattering of light materials during the conveying process. Stable conveying helps ensure that the light materials can smoothly enter the subsequent pipeline and be conveyed to the cyclone collector 11, improving the reliability of the conveying process. The larger connection port diameter provides a wider channel for the light materials, reducing the possibility of accumulation and blockage at the outlet, and ensuring the continuous and stable operation of the air separator. As the outlet 9 for light materials moves further away from the port diameter of the Z-type air separator 7, the airflow velocity increases at this point, assuming a constant airflow rate, according to the continuity equation. This high-speed airflow carries the light materials into the inlet of the cyclone collector 11, allowing them to enter the collector at a higher velocity and enhancing the centrifugal force within the collector. Driven by the high-speed airflow, the light materials entering the cyclone collector 11 form a more efficient rotating airflow. Based on the principle of centrifugal force, impurities and heavier particles in the light materials are thrown against the collector wall and separated, improving the purity and efficiency of the collected light materials.

[0040] The discharge port of the cyclone collector 11 is equipped with a star-shaped unloader 12.

[0041] The pulse valve assembly 3 includes: multiple pulse valves, each of which is electrically connected to a pulse controller to adjust the dispersing frequency under the control of the pulse controller; one end of each pulse valve is connected to the Z-type air classifier 7 and communicates with the sorting channel of the Z-type air classifier 7; the other end of each pulse valve is connected to multiple air outlets of the air tank 5; the side of the air tank 5 is provided with an air inlet valve 4 for connecting to a compressed air source; and the bottom of the air tank 5 is provided with a drain valve 6.

[0042] The air inlet valve 4 on the side of the air tank 5 is connected to the compressed air source. When the system starts, the air inlet valve 4 opens, and compressed air flows into the air tank 5 from the compressed air source. The air tank 5 acts as a storage container, storing a certain amount of compressed air to provide a stable air source for the pulse valves. Since compressed air usually contains moisture, a drain valve 6 is installed at the bottom of the air tank 5. Regularly opening the drain valve 6 can drain the moisture accumulated in the air tank 5, ensuring the quality of the compressed air inside and preventing moisture from adversely affecting the pulse valves and the system, such as corrosion and blockage. The pulse controller is electrically connected to multiple pulse valves and can send a series of electrical signals according to a pre-set program. The pulse controller controls the opening and closing of multiple pulse valves through the output electrical signals, thereby adjusting the dispersing frequency. For example, different dispersing frequencies may be needed to achieve the best air separation effect under different air separation conditions. When rapid dispersing of materials is required, the pulse controller can shorten the time interval between pulse valve openings and increase the frequency; conversely, it can extend the time interval and decrease the frequency. When the pulse controller sends an electrical signal, the corresponding pulse valve will receive the signal and open. Since one end of the pulse valve is connected to the air outlet of the air tank 5 and the other end is connected to the sorting channel of the Z-type air classifier 7, when the pulse valve is opened, the compressed air stored in the air tank 5 will quickly enter the sorting channel of the Z-type air classifier 7 through the pulse valve. The compressed air entering the sorting channel will form a strong airflow impact, which will disperse the material in the sorting channel, helping to separate the agglomerated material particles and better disperse materials of different densities and particle sizes in the airflow, thereby improving the air classification effect. After the electrical signal sent by the pulse controller ends, the pulse valve will close and stop blowing compressed air into the sorting channel, waiting for the next signal to arrive. This cycle repeats to achieve continuous material dispersion.

Similar or identical parts between embodiments can be referred to interchangeably.
