Description

A multi-purpose ash bin automatic blocking clearing device

Technical Field

The utility model belongs to the technical field related to ash bin cleaning, and in particular relates to a multi-purpose ash bin automatic blocking clearing device.

Background Art

In industrial production, dust removal is a process requirement as well as an environmental requirement. After being captured by the dust removal equipment, the dust will be temporarily stored in the ash bin, and then transported out by humidification or suction according to the process requirements. Since the two methods are not used at the same time and the use time is uncertain, the ash outlet that is not frequently used will be blocked and difficult to clean. The Chinese utility model patent with application number 201420606875.1 discloses a device for cleaning the silo material attached to the inner wall of a conical ash bin, including: a nozzle, an air collection bag, an air flow control valve, an air delivery duct and a compressed air intake pipe; there are at least two nozzles, and the nozzles are evenly fixed on the circumference of the ash bin opening; the air flow control valve is installed on the air delivery duct to control the air flow in the air collection bag to enter the ash bin; the air delivery duct is a hollow duct, one end of which is connected to the nozzle and the other end is connected to the air collection bag; the compressed air intake pipe is connected to the air collection bag to input compressed air into the air collection bag. The Chinese utility model patent with application number 201921196892.1 discloses a circular electrostatic precipitator ash bin auxiliary ash unloading device, including an ash hopper, the outer surface of the ash hopper is provided with an ash bin auxiliary ash unloading device, and the ash bin auxiliary ash unloading device is composed of a ring tube bracket, a nozzle, a connecting hose, upper and lower spray ring tubes, a branch pipe, a sleeve, a main air pipe and a solenoid valve. The outer wall of the ash hopper is fixedly installed with a ring tube bracket, the outer wall of the ash hopper is provided with evenly distributed interfaces and the interfaces are sleeved with nozzles, the end of the nozzle away from the ash hopper is fixedly connected with a connecting hose, and the upper surface of the ring tube bracket is clamped with upper and lower spray ring tubes. It can be seen that by installing high-pressure nitrogen at the ash hopper, it can act on the ash hopper wall of the ash hopper to clean up all the accumulated ash in the ash hopper, ensuring the smoothness and safety of the ash hopper during the entire ash unloading process. This gas blowing and cleaning method is not very effective for some sticky dusts because, even if the nozzles are arranged very densely, there is still a large area between the two nozzles that cannot be blown, and there will still be deposition problems, which will affect the normal operation of the ash bin.

See Figure 1-2, which is a schematic diagram of the structure of an embodiment of a multi-purpose ash bin automatic plugging device of the utility model. The ash bin 1 includes a straight section, a cone section and a bottom seal. The cone section is located at the bottom of the straight section, and the bottom seal is located at the bottom of the cone section. One side of the cone section is opened to connect the ash discharge pipe 2. The ash discharge pipe 2 is provided with an electric gate valve 3. The ash discharge pipe 2 is connected to the ash discharge pipeline. The cone section of the ash bin 1 is provided with a blowing mechanism and a cleaning mechanism for removing dust. The cleaning area of the cleaning mechanism is not less than the coverage area of the blowing mechanism. The ash discharge pipe 2 is blocked by the electric gate valve 3. A sealing ring is provided on the sealing surface of the valve plate on the electric gate valve 3, thereby avoiding the ash discharge pipe 2 from being blocked by water-containing dust when the ash bin 1 is humidified to transport dust outside. The ash bin 1 is provided with a blowing mechanism and a cleaning mechanism for removing dust, so that when the ash bin 1 discharges dust through the ash discharge pipe 2, the dust inside the ash bin 1 is powered by the blowing mechanism and the cleaning mechanism, thereby facilitating the dust to be discharged through the ash discharge pipe 2.

The blowing mechanism includes an air pump 4, an air blowing pipe 5, an air distribution pipe 7 and a nozzle 8. The outlet of the air pump 4 is connected to the air blowing pipe 5. The air blowing pipe 5 is provided with a valve 6 for controlling the opening and closing. The valve 6 is used to adjust the flow rate of the gas blown out. The output end of the air blowing pipe 5 is connected to the air distribution pipe 7. The air distribution pipe 7 is provided with a plurality of nozzles 8. The nozzles 8 are fixed on the mounting holes provided on the cone section of the ash bin 1. The air inside the air distribution pipe 7 is blown into the ash bin 1 through the nozzle 8, so that the dust inside the ash bin 1 is discharged by the electric gate valve 3 under the action of the airflow. In the embodiment, the air pump 4 can be a piston gas compressor or a screw gas compressor.

The cleaning mechanism includes a cleaning motor 9, a vertical rod 10, a side rod 11 and a cleaning brush 12. The cleaning motor 9 is installed on the top of the straight section of the ash bin 1. The output shaft of the cleaning motor 9 is connected to the vertical rod 10. The side rod 11 is welded on the surface of the vertical rod 10. The end of the side rod 11 is fixed with a cleaning brush 12, and the cleaning brush 12 contacts the inner wall of the cone section of the ash bin. When the output shaft of the cleaning motor 9 rotates with the vertical rod 10 and the side rod 11, the side rod 11 cleans the inner surface of the ash bin 1 through the cleaning brush 12 at the end, thereby removing dust from the inner surface of the ash bin 1 and preventing dust from collecting on the inner wall of the ash bin 1.

The outlet of the nozzle 8 is arranged obliquely downward, with an angle of 65° with the horizontal.

There are 4 to 6 side rods 11 and cleaning brushes 12 distributed around the vertical rod 10, at least one cleaning brush 12 is a rectangular structure, at least one cleaning brush 12 is an angular structure, and the angular structure cleaning brush is located at the connection between the straight section and the cone section and the connection between the cone section and the bottom seal.

The nozzles 8 are distributed in a circular array along the cone section of the ash bin, with 3 to 4 rows from top to bottom. The distance between adjacent nozzles 8 in each row is 60 mm through the air distribution pipe 7, and the distance between two rows is 200 mm. In order to achieve a better cleaning effect, the air distribution pipe 7 is divided into three rows, and the ratio of the diameter of each row is 15 mm: 20 mm: 30 mm from top to bottom, so that the gas flow rate sprayed by the three rows of nozzles 8 is different, so as to solve the practical problem that the dust inside the ash bin is more at the bottom, provide stable purge power, and prevent the bottom from being blocked and unable to be discharged.

The working principle and use process of the utility model are as follows: when in use, the ash discharge pipe 2 is blocked by the electric plug-in valve 3, and the ash bin 1 is used to collect dust. When the dust in the ash bin 1 needs to be discharged through the ash discharge pipe 2, the air generated by the air pump 4 is injected into the air distribution pipe 7 through the blowing pipe 5, and the air in the air distribution pipe 7 is blown out through the nozzle 8, so that the dust inside the ash bin 1 is moved and discharged from the ash discharge pipe 2 into the ash discharge pipeline. When the cleaning motor 9 is connected to an external power supply, the output shaft of the cleaning motor 9 rotates with the cleaning brush 12 through the vertical rod 10 and the side rod 11, and the cleaning brush 12 cleans the inner wall of the ash bin 1 to prevent dust from collecting on the inner wall of the ash bin 1.
