Description

Technical Field

[0001] This utility model relates to the field of pulse dust collector technology, and in particular to an anti-clogging device for pulse dust collectors. Background Technology

[0002] A pulse jet dust collector is a dust removal device that removes dust adhering to a filter medium by blowing compressed air. The dust conveying pipe in a pulse jet dust collector is located at the connection between the dust collector body and the cyclone separator bottle. Although the dust conveying pipe here is relatively short, it is the main channel for conveying dust from the dust collector to the collection device. Highly viscous or hygroscopic dust tends to accumulate on the inner wall of this pipe, resulting in a reduction in the flow area or even blockage. Therefore, anti-blocking devices are installed on the dust conveying pipe of the pulse jet dust collector to ensure the smooth conveying of dust.

[0003] Among them, a search revealed Chinese patent CN219848623U, which discloses an anti-clogging device for a pulse dust collector. In the application of the above-mentioned patent's technical solution, the scraper can only move back and forth and rotate within the ash conveying pipe of the pulse dust collector, resulting in insufficient ash removal within the ash conveying pipe. Therefore, in order to better realize the ash scraping function within the ash conveying pipe, promote technological progress in the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme for the ash scraping structure of the anti-clogging device that differs from the existing technology. Utility Model Content

[0004] The purpose of this invention is to solve the problem of insufficient ash scraping in the ash conveying pipe in existing anti-clogging devices, and to propose an anti-clogging device for pulse dust collectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pulse dust collector anti-clogging device includes a housing and a dust conveying pipe. A guide port is provided on one side of the housing, and a limiting port is provided on the other side of the housing. The limiting port communicates with the guide port. A sliding component is provided outside the limiting port. An electric push rod is fixedly connected to the top of the housing. The bottom end of the electric push rod is connected to the sliding component. The sliding component includes a support cylinder. Two drive motors are fixedly connected inside the support cylinder. A dust scraping component is provided at the output end of the drive motor. The dust scraping component extends from the top and bottom ends of the support cylinder.

[0007] Furthermore, a connecting cylinder is fixedly connected to one side of the support cylinder, a fixing block is fixedly connected to one end of the connecting cylinder, and the bottom end of the electric push rod is fixedly connected to the fixing block.

[0008] Furthermore, the scraping assembly includes a rotating column, which is fixedly connected to the output end of the drive motor. One end of the rotating column extends through the support cylinder and is fixedly connected to a connecting rod, and the other end of the connecting rod is fixedly connected to a scraping plate.

[0009] Furthermore, a side groove is provided on one side of the housing, which is connected to the limiting port. A baffle is slidably connected in the side groove, and the baffle is fixedly sleeved with the outer wall of the connecting cylinder.

[0010] Furthermore, a connecting cover is fixedly connected to one side of the housing, and the connecting cover blocks the outside of the guide opening.

[0011] Furthermore, support rings are bonded to both the top and bottom ends of the support cylinder, and the support rings are rotatably mounted to the rotating column via interlocking bearings.

[0012] Furthermore, a mounting plate is fixedly connected to one side of the housing, and the mounting plate is fixed to the ash conveying pipe by bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the motor, the scraping component scrapes the dust off the inner wall of the ash conveying pipe. Then, driven by the electric push rod, the sliding component moves within the guide port and the limit port to adjust the scraping position on the inner wall of the ash conveying pipe, thereby thoroughly cleaning the inner wall of the ash conveying pipe.

[0015] 2. The connecting cylinder drives the baffle to move in the side groove, so that the baffle is always blocked on one side of the limit port during dust cleaning, thereby preventing dust from entering the limit port and guide port, so as not to affect the operation of the sliding component and electric push rod.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A pulse dust collector anti-clogging device includes a housing 1 and an ash conveying pipe 13. A guide port 6 is provided on one side of the housing 1, and a limiting port 7 is provided on the other side of the housing 1. The limiting port 7 is connected to the guide port 6.

[0024] A sliding assembly 2 is provided on the outside of the limiting port 7. An electric push rod 5 is fixed to the top of the housing 1 by bolts. The bottom end of the electric push rod 5 is connected to the sliding assembly 2. Under the drive of the electric push rod 5, the sliding assembly 2 moves in the guide port 6 and the limiting port 7, thereby adjusting the scraping position on the inner wall of the ash conveying pipe 13 up and down.

[0025] The sliding assembly 2 includes a support cylinder 201, a connecting cylinder 202 is detachably fixed to one side of the support cylinder 201 by bolts, a fixing block 203 is welded to one end of the connecting cylinder 202, and the bottom end of the electric push rod 5 is fixedly connected to the fixing block 203.

[0026] Two drive motors 3 are fixed inside the support cylinder 201 by bolts. The drive motors 3 are dustproof stepper motors. The wires of the drive motors 3 are set as spring wires and pass through the connecting cylinder 202. Finally, they pass out from the side wall of the housing 1 to connect to the power supply. The spring wires prevent them from being pulled by the movement of the electric push rod 5. The output end of the drive motor 3 is equipped with a dust scraping component 4. The dust scraping component 4 passes out from the top and bottom of the support cylinder 201. Driven by the drive motor 3, the dust scraping component 4 scrapes the inner wall of the dust conveying pipe 13, thereby scraping off the dust on the inner wall of the dust conveying pipe 13.

[0027] The ash scraping assembly 4 includes a rotating column 401, which is fixedly connected to the output end of the drive motor 3. One end of the rotating column 401 extends out of the support cylinder 201 and is fixed to a connecting rod 402 by bolts. The other end of the connecting rod 402 is fixed to a ash scraping plate 403 by bolts. A gap is left between the two ash scraping plates 403 to avoid collision with the connecting cylinder 202. The ash scraping plate 403 is located inside the ash conveying pipe 13, and the gap between the ash scraping plate 403 and the inner wall of the ash conveying pipe 13 is 0.5-1mm.

[0028] A side groove 8 is provided on one side of the housing 1. The side groove 8 is connected to the limiting port 7. A baffle 9 is slidably connected in the side groove 8. The baffle 9 is fixedly sleeved with the outer wall of the connecting cylinder 202. The connecting cylinder 202 drives the baffle 9 to move in the side groove 8. A corrugated shielding curtain is fixed between the baffle 9 and the two ends of the side groove 8. So that when cleaning dust, the baffle 9 is always blocked on one side of the limiting port 7, thereby preventing dust from entering the limiting port 7 and the guide port 6.

[0029] A connecting cover 10 is fixed to one side of the housing 1 by bolts. The connecting cover 10 blocks the outside of the guide port 6, thereby facilitating the cleaning of the sliding component 2.

[0030] Support rings 11 are bonded to both the top and bottom of the support cylinder 201. The support rings 11 and the rotating column 401 are rotatably mounted through an interlocking bearing, which facilitates the rotation of the rotating column 401.

[0031] A mounting plate 12 is welded to one side of the housing 1. The mounting plate 12 is fixed to the ash conveying pipe 13 by bolts, which facilitates the connection between the anti-clogging device and the ash conveying pipe 13 of the pulse dust collector.

[0032] The working principle of this embodiment is as follows: When in use, the anti-blocking device is fixedly installed on the ash conveying pipe 13 by bolts through the mounting plate 12, so that the support cylinder 201 is located at the center of the ash conveying pipe 13.

[0033] During dust removal, the drive motor 3 is started, and the rotating column 401 rotates under the drive of the drive motor 3, thereby driving the connecting rod 402 and the scraper 403 to rotate, which in turn causes the scraper 403 to scrape the inner wall of the ash conveying pipe 13, thereby scraping off the dust on the inner wall of the ash conveying pipe 13. At the same time, the electric push rod 5 is started, and the sliding component 2 moves within the guide port 6 and the limiting port 7 under the drive of the electric push rod 5, thereby driving the scraper component 4 to move up and down, thereby adjusting the scraper 403 to scrape the inner wall of the ash conveying pipe 13, thereby thoroughly cleaning the inner wall of the ash conveying pipe 13.

[0034] At the same time, the connecting cylinder 202 drives the baffle 9 to move in the side groove 8, so that the baffle 9 always blocks one side of the limiting port 7 during dust cleaning, thereby preventing dust from entering the limiting port 7 and the guide port 6.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
