Description

TECHNICAL FIELD

[0001] The present application relates to an air cannon device used for unloading coal chute of thermal power plant and a method for returning the nozzle of the air cannon device to its original position. BACKGROUND

[0002] The unloading coal chute is a special channel used for receiving and transporting coal in power plants and other facilities, which is usually used in combination with train or automobile unloading coal operation. It is a kind of coal conveying building, which is mainly divided into two types of train unloading coal chute and automobile unloading coal chute, and the structure is usually designed as a slot type coal chute. During the transportation of coal, due to the humidity, particle size of coal and collision during the transportation process, etc., the coal in the unloading coal chute often appears to be blocked. This blockage not only affects the normal transportation efficiency of coal, but also can even cause the paralysis of the entire coal conveying system. The unloading coal chute air cannon unblocking device is a device specially used to solve the problem of coal accumulation and blockage in the unloading coal chute. It can generate a powerful shock wave by releasing high-pressure compressed air instantaneously to destroy the adhesion and friction between the coal, so as to restore the flowability of the material and ensure the smooth operation of the unloading process.

DETAILED DESCRIPTION

[0017] An embodiment provided by the present application: An air cannon device for clearing blockages in a coal unloading ditch includes a protective chamber 11 and a base 24. The protective chamber 11 is located on one side of the base 24. An adjusting chamber 17 is located on one side of the protective chamber 11. Both ends of the adjusting chamber 17 are rotatably connected to screws 15. A rotating shaft 16 is fixed between one end of the screws 15. A motor 10 is fixed inside the protective chamber 11. The output end of the motor 10 is fixedly connected to the drive end of the screws 15. A threaded seat 1 is threaded onto the screws 15. A movable seat 2 is fixed at the upper end of the threaded seat 1. Slide grooves 12 are provided on both sides of the upper end of the adjusting chamber 17 corresponding to the movable seat 2. A clamping block 3 is fixed at the upper end of one side of the movable seat 2. An air storage tank 4 is provided between the clamping blocks 3. Specifically, such as Figure 1 and Figure 5 As shown, when the motor 10 is started, the screw 15 rotates, driving the threaded seat 1 to move. The threads of the two screws 15 are in opposite directions, causing the two threaded seats 1 to move closer or further away from each other along the corresponding screws 15. This, in turn, drives the clamping block 3 to move through the moving seat 2. The two clamping blocks 3 cooperate with each other to position and clamp the gas tank 4, thereby protecting the gas tank 4. Furthermore, the inner wall of the clamping block 3 has several anti-slip protrusions evenly distributed, which further improves the stability of the clamping.

[0018] A pipe 6 is connected to the upper part of the front end of the gas storage tank 4, and a solenoid valve 5 is installed at the upper end of the pipe 6. Specifically, such as Figure 1 and Figure 2 As shown, when it is necessary to start the unblocking operation, the solenoid valve 5 is opened, and the high-pressure gas in the gas tank 4 can be quickly delivered to the unblocking nozzle 20 through the pipeline 6 to achieve efficient unblocking.

[0019] Both sides of the lower end of the base 24 are equipped with casters 13, and a push frame 9 is fixed on one side of the upper end of the base 24. Specifically, such as Figure 1 and Figure 2 As shown, the design of the push frame 9 makes it easy for staff to move and operate the entire device, while the universal wheels 13 make the device more flexible and convenient to move, and can adapt to the unblocking needs of different locations.

[0020] A support base 8 is fixed in the middle of one side of the push frame 9, and a receiving rod 7 is fixed in the middle of the support base 8 corresponding to the pipe 6. Specifically, such as Figure 1 and Figure 2 As shown, pipe 6 can be wound around the receiving rod 7 for arrangement and placement, improving the neatness and orderliness of pipe 6.

[0021] The pusher 9 has a relief cavity 14 in the middle, and a clearing nozzle 20 is provided in the relief cavity 14. One end of the clearing nozzle 20 is fixedly connected to the lower end of the pipe 6. Specifically, such as Figure 3 and 4 As shown in the figure, the unclogging nozzle 20 is inserted into the relief cavity 14 to position the unclogging nozzle 20.

[0022] The upper and lower ends of the relief cavity 14 are provided with adjustment chamber 23, and one end of the inner wall of the adjustment chamber 23 is connected to a spring 22; Specifically, such as Figure 3 and 4 As shown, when the guide block 19 is released, the spring 22 returns to its original position and the positioning block 21 moves, so that the positioning block 21 positions the upper and lower ends of the unclogging nozzle 20 together, preventing it from being bumped or scratched by the outside world due to random placement, and to a certain extent protecting the unclogging nozzle 20 and the pipeline 6.

[0023] One end of the spring 22 is fixed with a positioning block 21, and the front end of the positioning block 21 is fixed with a guide block 19. The front end of the adjustment chamber 23 is provided with a guide groove 18, and the guide groove 18 is slidably connected with the guide block 19. Specifically, such as Figure 3 and 4 As shown, the guide block 19 is pushed outward along the guide groove 18, which causes the spring 22 to compress and the positioning block 21 to move, making way for the unclogging nozzle 20.

[0024] When the motor 10 is started, the screw 15 rotates, driving the threaded seat 1 to move. The threads of the two screws 15 are in opposite directions, causing the two threaded seats 1 to move closer or further apart along the corresponding screws 15. This, in turn, drives the clamping block 3 to move via the moving seat 2. The two clamping blocks 3 cooperate to position and clamp the gas tank 4, thus protecting it. Furthermore, the inner wall of the clamping block 3 has several anti-slip protrusions evenly distributed, further improving the stability of the clamping. The design of the push frame 9 facilitates the movement and operation of the entire device by the operator, while the universal wheels 13 make the movement of the device more flexible and convenient, adapting to the unblocking needs in different locations. At the same time, the pipe 6 can be wrapped around the receiving rod 7 for organization and placement, improving the neatness and orderliness of the pipe 6. Then, the guide block 19 is pushed outward along the guide groove 18, which compresses the spring 22 and moves the positioning block 21 to make way for the unblocking nozzle 20. The unblocking nozzle 20 is then inserted into the clearance cavity 14 to position it. The guide block 19 is released, the spring 22 returns to its original position, and the positioning block 21 moves, so that the positioning block 21 positions the upper and lower ends of the unblocking nozzle 20 together, preventing it from being bumped or scratched by the outside world due to random placement. This provides a certain degree of protection for the unblocking nozzle 20 and the pipeline 6. In addition, when the unblocking operation needs to be started, the solenoid valve 5 is opened, and the high-pressure gas in the gas tank 4 can be quickly transported to the unblocking nozzle 20 through the pipeline 6 to achieve efficient unblocking. In summary, this device is convenient for replacing and maintaining the gas tank and for returning the pipeline and nozzle to their original positions.
