Description

Technical Field

[0001] This application relates to the field of cement production equipment technology, and in particular to a blockage removal device for an air chute. Background Technology

[0002] Air chutes are widely used for conveying powdery materials such as cement and fly ash. The principle is to fluidize the material by compressing air and let it slide down the chute by gravity.

[0003] The existing air conveying chute screen plates are prone to clogging during use, requiring regular cleaning. Cleaning necessitates shutting down the equipment, resulting in low production efficiency. Furthermore, current cleaning methods mainly rely on manual labor or air pressure. Manual cleaning requires removing the screen plates and cleaning each clogged screen hole individually, which is time-consuming and labor-intensive. Air pressure cleaning cannot guarantee the cleanliness of the screen plates and also leads to increased energy consumption.

[0004] Therefore, there is an urgent need for a clearing device for air chute to solve the above problems. Utility Model Content

[0005] This application provides a device for clearing blockages in an air chute, which aims to prevent powder from accumulating on the conveying path while saving manpower and resources.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] A blockage removal device for an air chute includes a frame, a chute box, an inlet pipe, an outlet pipe, a fan, multiple air ducts, and a vibration assembly;

[0008] The frame is fixedly installed in the working area, and the two ends of the frame along its length are staggered at different heights.

[0009] The trough is fixedly installed on the top of the frame. The length of the trough is consistent with the horizontal plane of the top of the frame. A sieve plate is provided inside the trough along its length. The sieve plate is spaced apart from the bottom of the trough and has sieve holes along its thickness.

[0010] The feed pipe is connected to the high end of the tank, and the discharge pipe is connected to the low end of the tank.

[0011] The fan is located at the bottom of the frame;

[0012] The input ends of the multiple air ducts are connected to the output end of the fan, and their output ends pass through the bottom of the trough and abut against the bottom of the sieve plate.

[0013] Multiple rotating rods are fixedly installed on the surface of the sieve plate, and a cover plate for covering the sieve holes is rotatably connected to the periphery of the multiple rotating rods.

[0014] The vibration assembly is disposed on the periphery of the tank, and the working end face of the vibration assembly abuts against the periphery of the tank.

[0015] Furthermore, the vibration assembly includes a vibration motor, a vibration rod, and a buffer component;

[0016] The vibration motor is located on the periphery of the lower end of the tank, and the output end of the vibration motor faces the outer wall of the tank.

[0017] One end of the vibrating rod is fixedly connected to the output end of the vibrating motor, and the other end is close to the outer wall of the tank.

[0018] The buffer is fixedly installed at the end of the vibrating rod away from the vibrating motor, and a portion of the peripheral surface of the buffer abuts against the outer wall of the tank.

[0019] Furthermore, this also includes branch pipes;

[0020] One end of the branch pipe is connected to the high end of the tank, and the other end is connected to the low end of the tank. A pressure sensor for detecting the internal pressure of the tank is provided in the middle of the branch pipe, and the output end of the pressure sensor is electrically connected to the input end of the vibration motor.

[0021] Furthermore, an inspection port is provided on the top of the tank, and a sealing plate is hinged to the edge of the inspection port.

[0022] Furthermore, a polyester filter cloth is adhered to the bottom of the sieve plate, and the filter pore size of the polyester filter cloth is smaller than the sieve pore size of the sieve plate.

[0023] Furthermore, the cover plate is provided with inclined blocks at intervals along the length of the groove of the slot box, and the inclination direction of the upper and lower ends of the inclined blocks is consistent with the inclination angle of the frame.

[0024] One or more technical solutions provided in the embodiments of this utility model have at least the following technical effects or advantages:

[0025] In this application, the staggered heights at both ends of the frame tilt the trough. Material enters the higher end through the feed pipe, flows along the trough under gravity, and permeates downwards through the screen holes. An airflow channel is formed between the screen plate and the trough bottom. A blower delivers compressed air to the bottom of the screen plate through an air duct, fluidizing the material, reducing friction, and promoting its sliding to the discharge pipe for discharge. Simultaneously, the airflow impacts the screen holes to remove clogging particles, and the air duct output end rests against the bottom of the screen plate to improve unclogging efficiency. A vibration component causes the trough to vibrate slightly, loosening blockages. Furthermore, the cover plate partially flips under airflow or vibration, disturbing blockages and causing them to fall off, reducing the frequency of manual cleaning and saving manpower and resources.

[0032] like Figures 1-2 As shown, an air chute unclogging device includes a frame 10, a chute box 11, an inlet pipe 12, an outlet pipe 13, a fan 14, multiple air ducts 17, and a vibration assembly 30. The frame 10 is fixedly installed in the working area, with its two ends staggered in height along its length. The chute box 11 is fixedly installed on top of the frame 10, with its length aligned with the horizontal plane of the top of the frame 10. A screen plate 20 is installed inside the chute box 11 along its length, spaced apart from the bottom of the chute box 11, and the screen plate 20 has screen holes 20 along its thickness. 1; The feed pipe 12 is connected to the high end of the tank 11, and the discharge pipe 13 is connected to the low end of the tank 11; The blower 14 is located at the bottom of the frame 10; The input ends of multiple air pipes 17 are connected to the output ends of the blower 14, and their output ends pass through the bottom of the tank 11 and abut against the bottom of the screen plate 20; Multiple rotating rods 21 are fixedly installed on the surface of the screen plate 20, and the periphery of the multiple rotating rods 21 is rotatably connected to a cover plate 22 for covering the screen holes 201; The vibration assembly 30 is located on the periphery of the tank 11, and the working end face of the vibration assembly 30 abuts against the periphery of the tank 11.

[0033] In the above scheme, the two ends of the frame 10 are staggered, causing the tank 11 to form an inclined angle. The material enters the higher end of the tank 11 through the feed pipe 12, flows along the length of the tank 11 under the action of gravity, and permeates downward through the screen holes 201 of the screen plate 20. The screen plate 20 is spaced apart from the bottom of the tank, forming an airflow channel. The blower 14 delivers compressed air to the bottom of the screen plate 20 through multiple air ducts 17, causing the material to form a fluidized state on the surface of the screen plate 20, reducing friction, promoting the material to slide along the tank 11 to the lower end, and finally being discharged through the discharge pipe 13. Among them, the compressed air generated by the blower 14 acts directly on the bottom of the screen plate 20 through the air ducts 17, and the airflow impacts upward from the screen holes 201, clearing the particles blocked in the screen holes 201. The output end of the air duct 17 abuts against the bottom of the screen plate 20, ensuring that the airflow acts on the screen hole 201 area, improving the unblocking efficiency. The vibration assembly 30, through the periodic vibration trough 11, causes the screen plate 20 and the material to vibrate slightly, further loosening the blockage. When the screen hole 201 is blocked, the cover plate 22 is partially flipped under the action of airflow or vibration, disturbing the blockage and promoting its dislodgement, reducing the frequency of manual cleaning, thereby saving manpower and resources.

[0034] The vibration assembly 30 includes a vibration motor 31, a vibration rod 32, and a buffer 33. The vibration motor 31 is located on the periphery of the lower end of the tank 11, and the output end of the vibration motor 31 faces the outer wall of the tank 11. One end of the vibration rod 32 is fixedly connected to the output end of the vibration motor 31, and the other end is close to the outer wall of the tank 11. The buffer 33 is fixedly located at the end of the vibration rod 32 away from the vibration motor 31, and part of the periphery of the buffer 33 abuts against the outer wall of the tank 11.

[0035] In the above scheme, the vibratory motor 31 is installed on the periphery of the lower end of the tank 11, with its output end facing the outer wall of the tank 11. When the vibratory motor 31 starts, the output end generates high-frequency reciprocating motion (e.g., 50-200Hz), driving the vibratory rod 32 to vibrate synchronously, while simultaneously causing the buffer 33 to continuously collide with the outer wall of the tank 11, causing the blockage on the screen plate 20 to loosen or fall off under the action of vibration. Moreover, the installation position of the vibratory motor 31 at the lower end can utilize the tilt angle of the tank 11 to more effectively transmit vibration energy to the screen plate 20 and the material, promoting the loosening of blockages. In this application, the buffer 33 is usually made of elastic material (e.g., rubber, polyurethane), which can effectively transmit vibration and reduce rigid impact on the tank 11.

[0036] It also includes a branch pipe 15; one end of the branch pipe 15 is connected to the high end of the tank 11, and the other end is connected to the low end of the tank 11. A pressure sensor 16 for detecting the internal pressure of the tank 11 is provided in the middle of the branch pipe 15. The output end of the pressure sensor 16 is electrically connected to the input end of the vibration motor 31.

[0037] In the above scheme, the two ends of the branch pipe 15 are connected to the high end and the low end of the tank 11, respectively, forming an internal pressure circulation loop. The pressure difference between the high end and the low end reflects the flow state of the material in the tank 11 and the degree of blockage of the screen plate 20. The pressure sensor 16 is installed in the middle of the branch pipe 15 to monitor the pressure value in the branch pipe 15 in real time. When the screen plate 20 is blocked, the material flow is obstructed, the pressure at the high end of the tank 11 increases, and the pressure at the low end decreases, resulting in an increase in the pressure difference in the branch pipe 15. The pressure sensor 16 converts the detected pressure signal into an electrical signal output and transmits the pressure signal to the control system of the vibrating motor 31 to realize the automatic start and stop of the vibrating motor 31, thereby reducing the need for manual operation and improving production efficiency.

[0038] To allow operators to easily observe the blockage status of the screen plate 20 (such as the degree of blockage of the screen holes 201 and the location of material accumulation) when the pressure sensor 16 or vibration assembly 30 cannot completely clear the blockage, an inspection port 111 is provided on the top of the tank 11, and a sealing plate 112 is hinged to the edge of the inspection port 111.

[0039] A polyester filter cloth 23 is adhered to the bottom of the sieve plate 20. The filter pore size of the polyester filter cloth 23 is smaller than the sieve hole size 201 of the sieve plate 20.

[0040] In the above scheme, polyester filter cloth 23 is adhered to the bottom of sieve plate 20, and its filter pore size (e.g., 0.1-1mm) is smaller than the sieve holes 201 of sieve plate 20, forming a second layer of fine filtration. The filter cloth can intercept fine particles (such as dust and debris) or adhesive materials, ensuring the purity of the conveyed materials. Furthermore, the air permeability of the polyester filter cloth 23 is matched with the airflow, ensuring that the airflow can effectively convey materials without causing filter cloth damage or material leakage due to excessive air pressure.

[0041] The cover plate 22 is provided with inclined blocks 24 at intervals along the length of the groove of the groove box 11. The inclination direction of the upper and lower ends of the inclined blocks 24 is consistent with the inclination angle of the frame 10.

[0042] In the above scheme, the inclined blocks 24 are spaced apart on the surface of the cover plate 22 along the length of the trough 11, and their inclination direction is consistent with the inclination angle of the frame 10 (e.g., 5°-15°), thus forming a flow guiding structure that matches the slope of the trough 11. When the airflow generated by the fan 14 flows upward from the bottom of the trough 11, the inclined blocks 24 guide the airflow along the length of the trough through their inclined surfaces to accelerate it, reducing the lateral diffusion of the airflow in the trough 11 and improving the material conveying efficiency. In addition, the inclined surfaces of the inclined blocks 24 can generate a slight pushing force on the material, preventing the material from accumulating or stagnating under the cover plate 22, which is especially suitable for materials with strong adhesion (such as wet fly ash).

[0043] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.

[0044] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this application.
