Description

Technical Field

[0001] The utility model relates to the technical field of electric dust collectors, in particular to an anti-blocking device for an electric dust collector ash hopper. Background Art

[0002] An electrostatic precipitator is a device used to remove particulate matter from exhaust gas. It applies a high-voltage electric field so that the charged particulate matter is adsorbed onto the electrode under the action of the electric field, thereby achieving the separation and removal of the particulate matter. The ash hopper of the electrostatic precipitator is an important component of the electrostatic precipitator. Its main function is to collect and store the dust captured by the precipitator.

[0003] When the existing electrostatic precipitator is working, the adsorbed dust will fall into the ash hopper for collection. However, when the ash hopper collects dust for a long time, some of the dust with adhesive properties will adhere to the ash hopper wall. Long-term aggregation will form lumps, which will cause the ash hopper to be blocked and affect the discharge of dust from the ash hopper. Therefore, we proposed a new type of electrostatic precipitator ash hopper anti-blocking device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when the ash hopper collects dust for a long time, some of the dust with adhesive properties will adhere to the ash hopper wall, and will form lumps due to long-term aggregation, thereby causing the ash hopper to be blocked and affecting the discharge of dust from the ash hopper to the outside. The utility model proposes an anti-blocking device for the ash hopper of an electrostatic precipitator.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-blocking device for an electrostatic precipitator ash hopper, comprising an ash hopper body and a motor, the ash hopper body is conical, the motor is arranged outside the ash hopper body, a rotating shaft is fixedly installed on the output end of the motor, the outer surface of the rotating shaft slides through the outer surface of the ash hopper body and extends to the inside, a gear is fixedly installed on the outer surface of the rotating shaft, a fixing ring is fixedly installed on the inner wall of the ash hopper body near the top, a U-shaped ring is rotatably arranged on the outer surface of the fixing ring, a face gear ring is fixedly installed on the top of the U-shaped ring, the gear is meshed with the face gear ring, and a scraper is symmetrically fixedly installed on the bottom of the U-shaped ring.

[0006] Furthermore, a bracket is fixedly mounted on the outer surface of the ash hopper body, and the motor is fixedly mounted on the top of the bracket.

[0007] Furthermore, the bottom of the ash hopper body is fixedly connected to a feed pipe, and the bottom end of the feed pipe is fixedly connected to a discharge pipe.

[0008] Furthermore, a connecting rod is fixedly connected between the outer surfaces of the two scrapers near the bottom, and the outer surfaces of the two scrapers are in contact with the inner walls of the ash hopper body and the discharge pipe.

[0009] Furthermore, a connecting bucket is fixedly installed on the top of the ash hopper body, and a protective cover is fixedly connected to the inner wall of the connecting bucket near the bottom.

[0010] Furthermore, the top of the connecting bucket is square-shaped, and the bottom of the connecting bucket is round-shaped.

[0011] Furthermore, one end of the discharge pipe is fixedly connected to an air duct, and a fan is provided on the outside of the air duct.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the motor is started to drive the rotating shaft to rotate, and the scraper is rotated under the cooperation of the gear and the face gear ring. Since the surface of the scraper is in contact with the inner wall of the ash hopper body and the inner wall of the discharge pipe at the same time, the dust or lumps attached to the inner wall of the ash hopper body and the discharge pipe can be scraped off or crushed, so as to avoid the dust from being attached to the inner wall of the ash hopper for a long time to form lumps, thereby improving the ash discharge effect of the ash hopper body.

[0014] 2. In the utility model, a protective cover is provided to protect the rotating shaft, gears and face gear rings to prevent dust from falling on these parts and affecting the mutual meshing.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides an anti-blocking device for an electrostatic precipitator hopper, including an ash hopper body 1 and a motor 3. The ash hopper body 1 is conical, and the motor 3 is arranged outside the ash hopper body 1. A rotating shaft 31 is fixedly installed at the output end of the motor 3. The outer surface of the rotating shaft 31 slides through the outer surface of the ash hopper body 1 and extends to the inside. A gear 32 is fixedly installed on the outer surface of the rotating shaft 31. A fixing ring 4 is fixedly installed near the top of the inner wall of the ash hopper body 1. A U-shaped ring 41 is rotatably arranged on the outer surface of the fixing ring 4. The top of the U-shaped ring 41 is fixedly installed. A face gear ring 42 is fixedly installed, the gear 32 is meshed with the face gear ring 42, a scraper 43 is symmetrically fixedly installed on the bottom of the U-shaped ring 41, a bracket 11 is fixedly installed on the outer surface of the ash hopper body 1, and the motor 3 is fixedly installed on the top of the bracket 11. The bottom of the ash hopper body 1 is fixedly connected with a discharge pipe 12, and the bottom end of the discharge pipe 12 is fixedly connected with a discharge pipe 13. A connecting rod 44 is fixedly connected between the outer surfaces of the two scrapers 43 near the bottom, and the outer surfaces of the two scrapers 43 fit the inner walls of the ash hopper body 1 and the discharge pipe 12.

[0024] The effect achieved by the entire embodiment 1 is that the rotating shaft 31 is driven to rotate by starting the motor 3, thereby driving the gear 32 to rotate synchronously. When the gear 32 is meshed with the face gear ring 42 and drives the face gear ring 42 to rotate, the U-shaped ring 41 can be driven to rotate on the surface of the fixed ring 4. When the U-shaped ring 41 rotates, the scraper 43 at the bottom of the U-shaped ring 41 can be driven to rotate. Since the surface of the scraper 43 is in contact with the inner wall of the hopper body 1 and the inner wall of the discharge pipe 12 at the same time, the dust or lumps attached to the inner wall of the hopper body 1 and the discharge pipe 12 can be scraped off or crushed to avoid the dust from adhering to the inner wall of the hopper for a long time to form lumps, thereby improving the ash discharge effect of the hopper body 1. The scraped dust falls into the discharge pipe 13 under the action of gravity and is discharged from the end of the discharge pipe 13.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, a connecting bucket 2 is fixedly installed on the top of the ash hopper body 1, a protective cover 21 is fixedly connected to the inner wall of the connecting bucket 2 near the bottom, the top of the connecting bucket 2 is square, and the bottom of the connecting bucket 2 is round. One end of the discharge pipe 13 is fixedly connected to the air duct 51, and the outside of the air duct 51 is equipped with a fan 5.

[0026] The effect achieved by the entire embodiment 2 is that, by providing a connecting bucket 2 and setting the top of the device to a square shape corresponding to the electrostatic precipitator, it is convenient to connect the ash hopper body 1 with the electrostatic precipitator, and avoid the top circular shape of the ash hopper body 1 being incompatible with the electrostatic precipitator. By providing a protective cover 21, the rotating shaft 31, the gear 42 and the face gear ring 42 are protected to avoid dust falling on this part and affecting the mutual meshing. When dust is discharged from the discharge pipe 13, the fan 5 is started to suck in and pressurize the external air, and the high-pressure airflow enters the discharge pipe 13 through the air duct 51. Under the action of air pressure, the efficiency of dust discharge from the discharge pipe 13 can be greatly improved, and at the same time, it can avoid the dust from being blocked in the discharge pipe 13 due to poor fluidity.

[0027] Working principle: When in use, the motor 3 is started to drive the shaft 31 to rotate, thereby driving the gear 32 to rotate synchronously. When the gear 32 is meshed with the face gear ring 42 and drives the face gear ring 42 to rotate, the U-shaped ring 41 can be driven to rotate on the surface of the fixed ring 4. When the U-shaped ring 41 rotates, the scraper 43 at the bottom of the U-shaped ring 41 can be driven to rotate. Since the surface of the scraper 43 is in contact with the inner wall of the hopper body 1 and the inner wall of the discharge pipe 12 at the same time, the dust or agglomerates attached to the inner wall of the hopper body 1 and the discharge pipe 12 can be removed. Scrape or crush the dust to prevent it from adhering to the inner wall of the ash hopper for a long time and forming lumps, so as to improve the ash discharge effect of the ash hopper body 1. The scraped dust falls into the discharge pipe 13 under the action of gravity and is discharged from the end of the discharge pipe 13. When the dust is discharged from the discharge pipe 13, the fan 5 is started to suck in and pressurize the external air, and the high-pressure airflow enters the discharge pipe 13 through the air duct 51. Under the action of air pressure, the efficiency of discharging dust from the discharge pipe 13 can be greatly improved, and at the same time, it can be avoided that the dust is blocked in the discharge pipe 13 due to its poor fluidity.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
