Description

Technical Field

[0001] This utility model relates to the technical field of silo unblocking equipment, and in particular to a vibrator. Background Technology

[0002] During the material unloading process, material often accumulates and clogs within the silo. Existing methods for unclogging typically involve manual unclogging after the machine is stopped, or using high-pressure gas to clear blockages via air cannons. However, existing air cannons usually have fixed nozzle positions, making it difficult to flexibly adjust their location according to the installation environment and silo structure. Furthermore, the coverage area of ​​a single air cannon is limited, resulting in a small radiation range. Therefore, there is an urgent need for a vibrator that allows for flexible nozzle installation while increasing the unclogging area. Utility Model Content

[0003] The purpose of this invention is to provide a vibrator that allows for flexible installation of the nozzle according to actual needs, while increasing the range of gas radiation, expanding the unblocking area, and improving the unblocking effect.

[0004] The present invention adopts the following technical solution:

[0005] A vibrator includes an air cannon, the interior of which is divided into two accommodating chambers by a partition. Each accommodating chamber is respectively provided with an air jet port, and each air jet port is connected to a nozzle via a flange. An injection assembly is provided on the outer shell of the air cannon corresponding to each accommodating chamber. A sealing sleeve is coaxially rotatably provided inside each nozzle, and injection holes are provided on the side walls of the sealing sleeve and the nozzle. A sealing plate is provided inside the nozzle at the end of the sealing sleeve, and guide holes are provided on the sealing sleeve and the sealing plate. When the injection hole is open, the guide hole is in a closed state, and when the injection hole is closed, the guide hole is in an open state.

[0006] Preferably, the two nozzles are disposed on both sides of the air cannon.

[0007] Preferably, a baffle is provided on the outer wall of the nozzle along its circumference.

[0008] Preferably, the injection holes on the nozzle are inclined away from the baffle.

[0009] Preferably, the end of the sealing sleeve and the guide holes on the sealing plate are coaxially arranged in multiple sets, both inner and outer.

[0010] Preferably, the injection hole on the sealing sleeve is not larger than the injection hole on the nozzle.

[0011] Preferably, the baffle is inclined toward the side near the injection hole.

[0012] Preferably, the outlet end of the nozzle is positioned downwards.

[0013] Preferably, a rubber pad is provided on the end face of the sealing sleeve that contacts the sealing plate, and the guide hole is opened through the rubber pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a partition inside the air cannon to divide its interior into two accommodating cavities, the nozzles that are connected to the accommodating cavities can be placed at different positions in the hopper to increase the radiation area of ​​the airflow and improve the unblocking effect; by connecting the nozzles to the nozzle of the air cannon using flanges, the setting angle of the nozzles can be flexibly adjusted to meet different installation conditions, thus enhancing the practicality of this utility model.

[0016] Figure 2 This is a cross-sectional view of the nozzle and sealing sleeve pipe according to an embodiment of this application;

[0017] Figure 3 This is a schematic diagram of the sealing plate in an embodiment of this application. Detailed Implementation

[0018] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0019] like Figures 1 to 3 As shown, the vibrator of this utility model includes an air cannon 1. The air cannon 1 is divided into two accommodating chambers 2 by a steel partition 11. Each accommodating chamber 2 is respectively provided with a jet nozzle 3 to increase the radiation range inside the silo. Each jet nozzle 3 is connected to a nozzle 4 by a flange 5. The flange 5 connection facilitates the adjustment of the installation angle of the nozzle 4 according to the installation conditions. The outlet end of the nozzle 4 is set downward so that the high-pressure airflow is evenly applied to the blockage material to achieve the unblocking operation. Each accommodating chamber 2 is provided with a jet assembly on the outer shell of the air cannon 1, which usually includes components such as a jet assembly, a quick-release valve, a three-way solenoid valve, and an air cannon 1 controller.

[0020] Furthermore, the two nozzles 4 are arranged on both sides of the air cannon 1, and preferably at the farthest point at both ends of the air cannon 1, in order to reduce the overlap between the airflows sprayed when clearing the inside of the hopper, reduce mutual interference, and at the same time increase the clearing range and improve the clearing effect.

[0021] Furthermore, a sealing sleeve 6 is coaxially rotatably installed inside each nozzle 4. The end of the sealing sleeve 6 located outside the nozzle 4 is rotatably connected to the flange 5. During installation, since the nozzle 4 is fixedly connected to the hopper, the normal rotation adjustment of the sealing sleeve 6 can be ensured. Injection holes 7 are opened on the side walls of both the sealing sleeve 6 and the nozzle 4. After the nozzle 4 is installed on the hopper, the injection holes 7 are located inside the hopper and are located close to the inner wall of the hopper. In addition, the injection holes 7 on the sealing sleeve 6 are not larger than the injection holes 7 on the nozzle, ensuring the smooth flow of air and preventing leakage of air to the surrounding area during the spraying process, thus ensuring the injection pressure of the airflow. When the sealing sleeve 6 is rotated so that its spray hole 7 is aligned with the spray hole 7 on the spray pipe 4, airflow can be ejected from the spray hole 7 to clean the inner wall of the silo, preventing material from adhering to the inner wall of the silo and reducing the impact of the internal space of the silo on the normal falling of the material; a sealing plate 8 is provided in the spray pipe 4 at the end of the sealing sleeve, and guide holes 9 are provided on the sealing sleeve and the sealing plate 8 for the passage of airflow when clearing blockages inside the silo; when the spray hole 7 is open, the guide hole 9 is in a closed state, ensuring that the airflow flows out from the spray hole 7 and acts on the inner wall of the silo to clean the inner wall of the silo; when the spray hole 7 is closed, the guide hole 9 is in a closed state, ensuring that the airflow smoothly enters the silo during normal blockage clearing.

[0022] Furthermore, a baffle 10 is provided along the circumference of the outer wall of the nozzle 4. The baffle 10 can block the airflow ejected from the injection hole 7, causing the airflow to flow towards the inner wall of the hopper. The side of the baffle 10 closest to the injection hole 7 is inclined towards the injection hole 7, while the injection hole 7 on the nozzle 4 is inclined away from the baffle 10. This provides guidance for the ejected airflow, causing it to move along the inner wall of the hopper and blow off the material adhering to the inner wall of the hopper, thus preventing material accumulation from affecting normal material discharge.

[0023] Furthermore, multiple sets of inner and outer guide holes 9 are coaxially arranged at the end of the sealing sleeve 6 and on the sealing plate 8 to ensure smooth airflow and increase the airflow area. The specific number of sets of guide holes 9 can be matched according to the size of each guide hole 9 and the diameter of the sealing plate 8 and the sealing sleeve 6. In addition, a rubber gasket is provided on the end face of the sealing sleeve 6 that contacts the sealing plate 8, and the guide holes 9 are opened through the rubber gasket. The rubber gasket can improve the tightness of the contact between the sealing sleeve 6 and the sealing plate 8, prevent leakage when the guide holes 9 are closed, ensure a constant airflow pressure from the injection hole 7, and ensure the unblocking effect.

[0024] This invention not only increases the airflow spray area and improves the unblocking effect, but also periodically cleans the inner wall of the hopper during the material feeding process, preventing material from adhering to the inner wall and affecting the internal space of the hopper, thus ensuring smooth material feeding. Furthermore, this invention can install a toothed adjusting disc at the end of the sealing sleeve 6, which is rotatably connected to the flange 5. A cylinder is installed outside the hopper, and a drive rack is installed at the end of the cylinder. By controlling the opening of the cylinder, the drive rack engages with the adjusting disc to rotate, realizing the switching between the spray hole 7 and the guide hole 9, improving operational convenience. The above is only one form of controlling the rotation of the sealing sleeve 6; other transmission methods can be flexibly selected and set according to actual conditions.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
