Description

Technical Field

[0001] The utility model relates to the technical field of dust collector ash hoppers, in particular to a dust return hopper for a bag dust collector. Background Art

[0002] Bag-type dust collector is a common industrial dust removal equipment used to remove dust and particulate matter generated in the industrial production process. It uses a series of bag filter materials as the filter medium, and separates the dust through gravity sedimentation, inertial collision, interception, capture and other mechanisms, and collects it with a dust return hopper. It can efficiently remove dust and particulate matter generated in industrial production, thereby achieving the purpose of purifying the air and ensuring the cleanliness of the environment and the air quality in the workplace.

[0003] After searching, the Chinese patent publication number is CN220424857U, which discloses a dust return hopper for a bag dust collector. The filtered dust particles enter the feed port of the dust return hopper. The vibration plate can move up and down through the driving motor, thereby driving the dust hopper to move. When the dust hopper moves, the scraper slidingly connected to it can clean the dust attached to the inner wall of the dust hopper. The vibration plate drives the rack to move at the same time, the rack drives the gear meshing with it to move, the gear drives the second shaft to move, and the shaft drives the blades to move to prevent dust from being blocked in the dust return hopper so that it can be smoothly transported to the discharge port.

[0004] However, during use of the above patent, the scraper cannot clean the cylindrical position of the upper part of the dust return hopper, and a large amount of dust will adhere to the surface of the scraper after being used for a period of time, which needs to be cleaned in time. However, the above patent is relatively cumbersome when cleaning the scraper, which affects the actual use of the device. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, a dust return hopper for a bag dust collector includes a base plate 1, an anti-blocking mechanism is arranged on the top of the base plate 1, a hopper 5 is installed on the top of the anti-blocking mechanism, a plurality of pillars 101 are welded on the top of the base plate 1, a mounting plate 102 is welded on the top of the pillars 101, a rotating groove 103 is opened on the top of the mounting plate 102, a rotating mechanism is installed on the top of the mounting plate 102, and a cleaning mechanism is arranged in the rotating mechanism.

[0026] The rotating mechanism includes a first motor 201, which is connected to the top of the mounting plate 102 by bolts. The output shaft of the first motor 201 is connected to a gear 202 by a key. The outer side of the mounting ring 301 is connected to a gear ring 203 by a key. The gear 202 and the gear ring 203 are meshed. The movement of the first motor 201 drives the gear 202 to rotate, thereby driving the gear ring 203 to rotate. The cleaning mechanism includes a plurality of stabilizing columns 304, which are slidably connected to the rotating groove 103. The rotating groove 103 is embedded with a steel ball for improving sliding smoothness. The top of the stabilizing column 304 is connected to the rotating groove 103 by a steel ball for improving sliding smoothness. A mounting ring 301 is connected by screws, and a plurality of limit grooves 302 are provided on the top of the mounting ring 301. The limit grooves 302 are rectangular grooves, and a cleaning brush 303 is connected in the limit grooves 302 by bolts. The inner side of the cleaning brush 303 fits against the inner wall of the hopper 5, and the mounting ring 301 is driven to rotate by the rotation of the gear ring 203, thereby driving the cleaning brush 303 to rotate along the inner wall of the hopper 5, thereby achieving comprehensive cleaning of dust particles adhered to the inner wall of the hopper 5. During the rotation of the mounting ring 301, the stabilizing column 304 is driven to slide in the rotating groove 103, thereby increasing the rotation stability.

[0027] The anti-blocking mechanism includes a discharge pipe 401, which is welded to the top of the base plate 1. A second motor 402 is installed on the outer wall of the discharge pipe 401 through a bracket. A rotating shaft 403 is rotatably connected to the inner wall of the discharge pipe 401 through a bearing. The rotating shaft 403 is connected to the output shaft of the second motor 402 through a coupling. A plurality of stirring rods 404 are welded to the rotating shaft 403. The second steel ball (404) of the stirring rod is a hollow cylindrical tube made of stainless steel.

[0028] Working principle: When in use, after the filtered dust particles enter the hopper 5, the first motor 201 moves, driving the gear 202 to rotate, thereby driving the ring gear 203 to rotate. Through the rotation of the ring gear 203, the mounting ring 301 is driven to rotate, thereby driving the cleaning brush 303 to rotate along the inner wall of the hopper 5, thereby achieving comprehensive cleaning of the dust particles adhered to the inner wall of the hopper 5. During the rotation of the mounting ring 301, the stabilizing column 304 will be driven to slide in the rotating groove 103, thereby increasing the rotation stability and reducing shaking. At the same time, the second motor 402 moves, driving the rotating shaft 403 to rotate, and then driving the stirring rod 404 to rotate, achieving continuous stirring to prevent blockage. After a period of use, when the cleaning brush 303 needs to be cleaned, the cleaning brush 303 is taken out upward along the limiting groove 302 for cleaning, which is convenient for actual use.
