Description

Technical Field

[0001] This utility model belongs to the technical field of air pulse unblocking devices, specifically a buffered annular air pulse unblocking device with directional ring spray. Background Technology

[0002] An air pulse unblocking device is a device used to remove blockages from various containers or pipes. It uses pulsed airflow generated by compressed air to achieve the unblocking function. The device first compresses and stores air in an air tank. When unblocking is needed, the opening time and frequency of the valve are precisely controlled by a pulse controller, so that the compressed air in the air tank is released in the form of short and strong pulses. These high-speed pulsed airflows are directed to the blockage site through the blow pipe and nozzle. The impact force and vibration generated by the airflow can effectively break and loosen the blockage, causing it to fall off the attached surface and be discharged with the airflow or gravity, thereby achieving the purpose of unblocking.

[0003] In existing technologies, air pulse unblocking devices can achieve 360° annular unblocking and are typically installed at the bottom of material silos or chutes to achieve the unblocking effect. However, they usually have the following problems: The spray angle of the annular air outlet pulse nozzle of the air pulse unblocking device is usually fixed. In practical applications, the distribution and shape of the blockage are often irregular. A fixed spray angle may not be able to fully cover all blocked areas. For certain specific blockage situations, there may be an optimal spray angle that allows the pulse airflow to impact the blockage in the most effective way, breaking it up and removing it. However, a fixed-angle nozzle cannot be adjusted according to specific situations and can only spray at a preset angle. This may result in the airflow impact force not being able to fully act on the blockage, requiring more pulses and time to achieve the unblocking purpose, thus reducing the unblocking efficiency. Secondly, the annular air outlet pulse nozzle will come into contact with the material, and the material will rub against the annular air outlet pulse nozzle during the flow process. Over time, this will cause wear on the outer wall of the annular air outlet pulse nozzle, affecting its service life.

[0004] Therefore, a buffered annular air pulse unblocking device with directional ring spray is proposed to address the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 7 As shown, this utility model provides a buffered annular air pulse unblocking device with directional annular spray, including an air main pipe 1. An air storage tank 2 and a particle filter assembly 3 are arranged sequentially from left to right on the air main pipe 1. An annular air pipe 4 is connected to the right end of the air main pipe 1. A plurality of evenly distributed branch hoses 5 are connected to the top of the annular air pipe 4. An annular air outlet pulse nozzle 6 is connected to the end of the branch hoses 5. An annular air outlet pulse nozzle 6 is connected to a spray angle adjustment assembly 7. An anti-wear assembly 8 is sleeved on the outer side of the spray end of the annular air outlet pulse nozzle 6.

[0032] The spray angle adjustment component 7 includes an annular air outlet pulse nozzle 6 with an annular flexible belt 701 connected to the outside. The annular flexible belt 701 is connected to a fixed ring 702. Multiple evenly distributed first rotating shafts 703 are installed on the fixed ring 702. The first rotating shafts 703 are connected to an electric telescopic rod 704. One end of the electric telescopic rod 704 is connected to a second rotating shaft 705. The second rotating shaft 705 is installed on the annular air outlet pulse nozzle 6. It can flexibly adjust the spray angle according to different unblocking needs. By adjusting the spray angle, the pulse airflow can impact the blockage at the optimal angle, making better use of the impact force and vibration effect of the airflow, thereby more effectively breaking and loosening the blockage, reducing the number of unblocking times and time, and improving the unblocking efficiency.

[0033] The wear-resistant component 8 includes a fixed collar 801 connecting the annular flexible belt 701. A replacement collar 802 is provided on the side of the fixed collar 801 away from the annular flexible belt 701. A convex ring 803 and a groove 804 are respectively provided at corresponding positions of the fixed collar 801 and the replacement collar 802. The convex ring 803 extends into the groove 804. A plurality of equidistant positioning rings 805 are provided on the outer wall of the convex ring 803. A positioning groove 806 is opened on the inner wall of the groove 804 at the position corresponding to the positioning rings 805. A sealing ring 807 is provided between the fixed collar 801 and the replacement collar 802. The sealing ring 807 is sleeved on the convex ring 803. A protective ring is provided on the outside of the annular air outlet pulse nozzle 6 to avoid friction between the annular air outlet pulse nozzle 6 and the material flow, thereby extending the service life of the annular air outlet pulse nozzle 6. A corresponding connection structure is provided to facilitate the replacement of the replacement collar 802.

[0034] Specifically, the left end of the air main pipe 1 is connected to an air source, which can be an air compressor. The air tank 2 needs to be connected to the air source to continuously replenish compressed air, maintain stable pressure inside the tank, and ensure sufficient air reserve for pulse clearing. An air inlet valve 9 is installed on the air main pipe 1 on the left side of the air tank 2. By opening and closing the air inlet valve 9, the compressed air entering the device can be precisely controlled. A pressure regulating valve 10 is installed on the air main pipe 1 between the air tank 2 and the particulate filter assembly 3. The pressure regulating valve 10 can adjust the unstable input pressure to a stable output pressure, providing a stable power source for the air pulse clearing device.

[0035] Furthermore, a drain kit 11 is connected to one side of the air tank 2 near the bottom. During the storage of compressed air, due to temperature changes and other reasons, water vapor in the air will condense into liquid water and accumulate at the bottom of the air tank 2. The drain kit 11 can periodically or automatically drain this condensate to prevent excessive accumulation of condensate in the air tank 2.

[0036] Furthermore, the particle filter assembly 3 includes a housing 301, with sealing end caps 302 connected to both ends of the housing 301. Two corresponding filter plates 303 are disposed inside the housing 301, and adsorption filler 304 is filled between the filter plates 303 to prevent particulate impurities in the airflow from clogging or throttling at the annular air outlet pulse nozzle, which would cause uneven airflow and affect the unclogging effect. Secondly, it can also prevent particulate impurities from contaminating the material.

[0037] It is worth noting that a ball valve 12 and a solenoid valve 13 are installed on the branch hose 5. The ball valve 12 can control the on / off state of the annular air vent pulse nozzle 6, and the solenoid valve 13 is used to control the generation of pulses.

[0038] It is worth noting that a sealing washer 14 is provided on the side of the fixing ring 702 away from the electric telescopic rod 704, and evenly distributed fixing bolts 15 are provided on the fixing ring 702. The screw of the fixing bolt 15 passes through the fixing ring 702 and the sealing washer 14. The fixing ring 702 is connected to the discharge pipe through the fixing bolt 15, and the sealing washer 14 can increase the sealing between the fixing ring 702 and the discharge pipe.

[0039] The electric telescopic pole 704 is existing technology and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail here.

[0040] Working principle and process: A through hole is made at the corresponding position on the discharge pipe to install the injection angle adjustment component 7 and the annular air outlet pulse nozzle 6. The left end of the air main pipe 1 is connected to an air source to continuously replenish compressed air, maintain stable pressure in the tank, and ensure sufficient air reserve for pulse clearing. The electric telescopic rod 704 of the injection angle adjustment component 7 is activated. The injection angle of the annular air outlet pulse nozzle 6 is adjusted by the extension and retraction of the electric telescopic rod 704. The annular flexible belt 701 connected to the annular air outlet pulse nozzle 6 can deform to avoid interfering with the annular airflow. The positional change of the pulse nozzle 6 allows the pulsed airflow to impact the blockage at the optimal angle. The airflow is drawn out from the air tank 2, passes through the annular air pipe 4 and the branch hose 5 in sequence, and is discharged from the annular air outlet pulse nozzle 6 to clear the blockage. When the airflow passes through the particle filter assembly 3, the filter plate 303 and the adsorption packing 304 can remove particulate impurities in the airflow, avoiding blockage or throttling of particulate impurities in the airflow at the annular air outlet pulse nozzle, which would cause uneven airflow and affect the blockage clearing effect. Secondly, it can also prevent particulate impurities from contaminating the material.
