Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and more specifically relates to a wear-resistant dust collector. Background Art

[0002] In actual applications, dust collectors are mostly used to collect metal debris. The metal debris rotates downward in a spiral shape at high speed in the lower funnel of the dust collector, and finally falls into the collection bucket below the funnel. In this process, the high-speed rotating metal debris will rub against the inner wall of the funnel, causing wear of the inner wall of the funnel. In severe cases, holes will appear in the funnel. Because the funnel and the dust collector are integrally connected, it is necessary to manually repair the holes or replace the dust collector with a new one, which not only wastes manpower but also increases the cost of use.

[0021] See also Figures 1 to 4 The wear-resistant dust collector provided by the utility model is now described. The wear-resistant dust collector comprises a dust collector body 10 and a funnel 20. The funnel 20 is detachably connected to the bottom of the dust collector body 10. The funnel 20 has a through cavity 21 that passes through from top to bottom. The funnel 20 gradually gathers toward the central axis from top to bottom. The funnel 20 comprises an outer bucket body 22 that is detachably connected to the bottom of the dust collector body 10 and an inner bucket body 23 embedded in the outer bucket body 22. The inner circumferential wall of the inner bucket body 23 is connected with a rib 30 that extends along the slope direction of the inner bucket body 23 and is used to buffer the airflow. The inner circumferential wall of the inner bucket body 23 is coated with an anti-wear coating layer 40.

[0022] The rib plate 30 is first welded to the inner peripheral wall of the inner bucket body 23 , and then the anti-wear coating layer 40 is coated on the inner peripheral wall of the inner bucket body 23 .

[0023] The embodiment of the present application provides a wear-resistant dust collector. In its actual use, the detachable connection between the funnel 20 and the dust collector body 10 not only facilitates the staff to replace the inner bucket body 23 in time, but also facilitates the staff to observe the wear condition inside the inner bucket body 23. When the airflow drives the metal debris to rotate and move downward from the funnel 20, the airflow collides with the ribs 30, buffering the airflow and reducing the flow speed of the airflow, thereby reducing the degree of wear of the inner wall of the funnel 20 by the metal debris, and also enhancing the wear resistance of the inner wall of the funnel 20 through the anti-wear coating layer 40, avoiding the damage of the funnel 20, saving manpower, and reducing the use cost.

[0024] Compared with the prior art, the wear-resistant dust collector provided in the present embodiment can not only buffer the airflow in the funnel 20 through the ribs 30 to reduce the degree of wear of the inner wall of the funnel 20 by metal debris, but also enhance the wear resistance of the inner wall of the funnel 20 through the anti-wear coating layer 40, thereby avoiding damage to the funnel 20, eliminating the tedious process of manually repairing the leaks, saving manpower, and the detachable connection between the funnel 20 and the dust collector body 10 allows the inner bucket body 23 to be replaced in time without replacing the entire dust collector, thereby reducing the cost of use.

[0025] In a possible implementation, the dust collector body 10 is configured as follows: Figures 1 to 3 The structure shown, see Figures 1 to 3 A first flange 50 is disposed at the lower end of the dust collector body 10 , and a second flange 60 is disposed at the upper end of the outer bucket body 22 . The first flange 50 and the second flange 60 are connected by a bolt connector 80 .

[0026] Specifically, the connection between the first flange 50 and the second flange 60 by the bolt connector 80 can improve the sealing performance between the funnel 20 and the dust collector body 10 .

[0027] Furthermore, a sealing gasket is provided between the first flange 50 and the second flange 60 .

[0028] In some embodiments, see Figures 1 to 4 A third flange 70 is provided at the upper end of the inner bucket body 23 and is located between the first flange 50 and the second flange 60 . The first flange 50 , the second flange 60 and the third flange 70 are connected by a bolt connector 80 .

[0029] Specifically, by simultaneously connecting the first flange 50, the second flange 60 and the third flange 70 together through the bolt connector 80, the inner bucket 23, the outer bucket 22 and the dust collector body 10 can be made into a whole, thereby improving the stability of their relative positions and preventing the inner bucket 23 from rotating relative to the outer bucket 22 under the influence of the airflow.

[0030] In some embodiments, see Figures 1 to 4A plurality of first mounting grooves 51 opening outward are provided on the outer peripheral wall of the first flange 50, a plurality of second mounting grooves 61 corresponding to the first mounting grooves 51 are provided on the outer peripheral wall of the second flange 60, a plurality of third mounting grooves 71 corresponding to the second mounting grooves 61 are provided on the outer peripheral wall of the third flange 70, and the bolt connectors 80 are provided through the corresponding first mounting grooves 51, the second mounting grooves 61 and the third mounting grooves 71.

[0031] Specifically, the bolt connector 80 includes bolts located in the first mounting groove 51, the second mounting groove 61 and the third mounting groove 71 and nuts threadedly connected to the bolts. During installation, the first mounting groove 51, the second mounting groove 61 and the third mounting groove 71 are first aligned with each other, and then the nut is pre-connected to the lower end of the bolt, and the distance between the nut and the bolt head is kept greater than the total thickness of the first flange 50, the second flange 60 and the third flange 70, and then the bolt is inserted into the first mounting groove 51, the second mounting groove 61 and the third mounting groove 71 to reduce the number of turns of the nut during the locking process. In addition, during disassembly, it is only necessary to slightly loosen the bolt and the nut, and move the bolt and the nut as a whole to the opening of the first mounting groove 51, the second mounting groove 61 and the third mounting groove 71 (outside of the first flange 50, the second flange 60 and the third flange 70), so as to complete the disassembly, thereby realizing the rapid disassembly of the first flange 50, the second flange 60 and the third flange 70 and improving the work efficiency.

[0032] In a possible implementation, the inner bucket 23 is formed as follows: Figure 1 The structure shown, see Figure 1 The lower end of the inner bucket body 23 is connected to a material guide cylinder 231 extending downward to the bottom of the outer bucket body 22.

[0033] Specifically, the material guiding cylinder 231 has a material guiding cavity which is connected vertically, and the material guiding cylinder 231 can extend downward to a collecting hopper which is pre-placed under the funnel 20 to ensure that all impurities fall into the collecting hopper.

[0034] In some embodiments, see Figure 1 A threaded sleeve is provided on the outer peripheral wall of the material guide cylinder 231 with a fixing sleeve 90 for abutting and cooperating with the lower end of the outer bucket body 22 .

[0035] Specifically, the fixing sleeve 90 can be rotated and moved upward on the outer periphery of the material guide cylinder 231 to press against the lower end of the outer bucket body 22 , thereby limiting the axial position of the inner bucket body 23 and improving the stability of the relative position of the inner bucket body 23 and the outer bucket body 22 .

[0036] In a possible implementation, the rib plate 30 is formed as follows: Figure 1 The structure shown, see Figure 1A plurality of ribs 30 are arranged at intervals in the circumferential direction of the inner bucket body 23 .

[0037] Specifically, the arrangement of multiple ribs 30 can buffer the airflow multiple times, rapidly reduce the flow velocity of the airflow, minimize the wear of the inner bucket body 23, and increase the service life of the inner bucket body 23.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
