Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a dust collector for a dust removal device. Background Technology

[0002] The dust collector in a dust collector is a device used to collect and remove dust accumulated inside the dust collector. Its main function is to periodically remove the dust collected on the filter bags, allowing it to fall into the dust hopper and then be discharged through the dust removal system. A pulse jet cleaner is a high-efficiency dust collection device that uses pulse jet cleaning technology to remove dust from filter bags. Pulse jet cleaning is a common cleaning technology used in baghouse dust collectors. Its working principle involves rapidly injecting compressed air into the interior of the filter bags for a short period, generating an instantaneous high-pressure airflow that causes the filter bags to rapidly expand and contract, thereby shaking off the dust adhering to the outer surface of the filter bags.

[0003] Currently, dust collection equipment collects dust from pulse cleaning by installing a dust collection hopper at the bottom. The dust collection hopper is connected to the dust collection equipment body. Although dust collection is convenient, when air enters the dust collection equipment body, the dust collected in the hopper will diffuse and enter the hopper, causing the dust in the hopper to be stirred up and interfering with the operation of the dust collection equipment. Dust collected in the hopper for a long time can easily block the outlet, making it inconvenient for dust to be discharged from the hopper, and even causing dust to stick to the hopper.

[0022] like Figures 1 to 4 As shown, the dust collector of this embodiment includes a dust collection hopper 1. A dust collector body 3 is mounted on the top of the dust collection hopper 1 via an assembly mechanism 2. An anti-disturbance mechanism 4 is provided at the lower end of the dust collector body 3 above the dust collection hopper 1. A dust collection mechanism 5 is provided inside the dust collection hopper 1 below the anti-disturbance mechanism 4. A dust collection pipe 6 is connected to the bottom of the dust collection hopper 1. A dust discharge valve 61 is provided at the lower end of the dust collection pipe 6. A dust-laden inlet is provided on one side of the dust collector body 3 above the anti-disturbance mechanism 4. 7. A dust collector bag 8 is installed inside the dust collector body 3 above the dust inlet 7. A pulse jet cleaner 9 is installed on the dust collector body 3 above the dust collector bag 8. A purification outlet 10 is installed on the dust collector body 3 on the side away from the dust inlet 7 above the pulse jet cleaner 9. The dust discharge is smooth, convenient and with little retention. It improves the upward flow of air in the dust collector body 3 and prevents dust-laden air from flowing from the dust inlet 7 to the dust collection hopper 1. The anti-disturbance mechanism 4 prevents air disturbance from disturbing the dust collected in the dust collection hopper 1.

[0023] Specifically, the anti-disturbance mechanism 4 includes an anti-disturbance plate 41, a dust collection port 42, an inclined plate 43, and an upward guide plate 44. The dust collector body 3 below the dust inlet 7 is equipped with an anti-disturbance plate 41, a dust collection port 42 is provided on the anti-disturbance plate 41, an inclined plate 43 is provided inside the dust collection port 42, and an upward guide plate 44 is provided on the top of the anti-disturbance plate 41. The upward guide plate 44 on the top of the anti-disturbance plate 41 at the outlet of the dust inlet 7 guides and lifts the dust-laden air, thereby enhancing the upward flow of air within the dust collector body 3.

[0024] Furthermore, the dust collection mechanism 5 includes a servo motor 51, a motor base 52, and a discharge screw 53. The servo motor 51 is installed at the upper end of the dust collection hopper 1 through the motor base 52. The output end of the servo motor 51 is connected to the discharge screw 53 through a coupling. The lower end of the discharge screw 53 is located in the dust collection pipe 6 above the dust discharge valve 61. The servo motor 51 drives the discharge screw 53 to rotate in the dust collection hopper 1, and the dust is discharged from the dust collection pipe 6 into the dust collection hopper 1 through the discharge screw 53.

[0025] Furthermore, the ash collection mechanism 5 also includes a connecting rod 54 and a scraper 55. The discharge screw 53 is provided with a scraper 55 through the connecting rod 54. The side of the scraper 55 away from the connecting rod 54 is in contact with the inner wall of the ash collection hopper 1. The scraper 55 scrapes the inner wall of the ash collection hopper 1 to remove the dust adhering to the inner wall of the ash collection hopper 1.

[0026] Furthermore, several rising guide plates 44 are provided. The rising guide plate 44 is inclined on the side near the dust inlet 7. The inclined plate 43 is inclined in the same direction as the inclined surface of the rising guide plate 44. One of the rising guide plates 44 is located near the dust inlet 7. The inclined plate 43 in the ash discharge port 42 can block air from entering the ash collection hopper 1.

[0027] Furthermore, the assembly mechanism 2 includes a first flange 21, a second flange 22, and assembly bolts 23. The ash collection hopper 1 is arranged in a conical cylindrical structure. The top of the ash collection hopper 1 is provided with a first flange 21, and the bottom of the dust collector body 3 is provided with a second flange 22. The first flange 21 and the second flange 22 are fixed together by assembly bolts 23. The dust collector body 3 can be a cubic or cylindrical structure. A sealing ring is provided between the first flange 21 and the second flange 22. The ash collection hopper 1 with the ash collection mechanism 5 is fixedly installed at the bottom of the dust collector body 3.

[0028] Furthermore, the top of the motor base 52 is designed with an arc surface structure, so dust will not accumulate on the motor base 52. The top of the servo motor 51 is equipped with a vibration plate, and the top of the vibration plate abuts against the inclined plate 43. The vibration plate transmits the vibration of the servo motor 51 to the inclined plate 43 and the anti-interference plate 41. When the ash collection hopper 1 discharges ash, the vibration cleans the inclined plate 43 and the rising guide plate 44.

[0029] The usage method of this embodiment is as follows: First flange 21 and second flange 22 are fixed together using assembly bolts 23. Assembly mechanism 2 fixes the dust collection hopper 1, equipped with dust collection mechanism 5, to the bottom of the dust collector body 3. Dust-laden air enters the dust collector body 3 through dust inlet 7. The rising guide plate 44 on top of the anti-disturbance plate 41 at the outlet of dust inlet 7 guides and lifts the dust-laden air. The rising guide plate 44 enhances the upward flow of air within the dust collector body 3, and the inclined plate 43 in the dust collection port 42 prevents air from entering the dust collection hopper 1, thus preventing dust-laden air from flowing from dust inlet 7 to the dust collection hopper 1. The anti-disturbance mechanism 4 prevents air from disturbing the dust collected in the dust collection hopper 1. The dust-laden air rises and passes through the dust collector bag 8 for filtration, and is discharged through the purification outlet 10 after purification. The pulse cleaning machine 9 is started to perform pulse cleaning on the dust collector bag 8. The cleaned dust is then removed by the anti-disturbance mechanism. The dust falls into the dust collection hopper 1 through the dust discharge port 42 of the baffle plate 41. Since the rising guide plate 44 is inclined on the side near the dust inlet 7, and the inclined plate 43 is inclined in the same direction as the inclined surface of the rising guide plate 44, the dust enters the dust collection hopper 1 along the inclined surfaces of the rising guide plate 44 and the inclined plate 43. When discharging dust, the receiving box is placed at the bottom of the dust discharge pipe 6, and the dust discharge valve 61 on the dust discharge pipe 6 is opened. The servo motor 51 drives the discharge screw 53, the connecting rod 54 and the scraper 55 to rotate in the dust collection hopper 1. The dust is discharged from the dust discharge pipe 6 to the dust collection hopper 1 through the discharge screw 53. The scraper 55 scrapes the inner wall of the dust collection hopper 1, so the dust discharge is smooth, convenient and with little retention. The inclined plate 43 protects the dust discharge port 42 from overflow and prevents the dust inside the dust collection hopper 1 from rising into the dust collector 3, reducing the dust interference of the dust collection hopper 1 to the dust collector 3.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
