Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter bag removal, in particular to a filter bag removal device for a bag filter. Background Art
[0002] There are a large number of bag dust collection systems in the production of new dry cement, and the service life of the filter bags is short. In order to ensure the dust collection effect and achieve exhaust gas emissions in compliance with national standards, the filter bags in the dust collector need to be replaced regularly. However, due to the large number of filter bags in the dust collector, it takes a lot of time and manpower to remove and extract the waste filter bags from the dust collector board, and the surface of the filter bags absorbs a lot of dust, and even has a hardened crust. When the filter bags are removed from the dust collector board manually, not only is the labor intensity high, the removal time is long, and it is time-consuming and laborious, but also a lot of dust will be generated during the removal, which seriously endangers human health. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a bag filter removal device for a dust bag collector which can replace manual rapid extraction of waste filter bags and is convenient, fast, time-saving and labor-saving.
[0004] In order to solve the above technical problems, the technical solution of the utility model is: a bag filter bag removal device for a bag dust collector, comprising a support seat and a winding drum, a reduction motor is installed on the support seat, the output end of the reduction motor is connected to the winding drum through a coupling, and a clamping rod is fixedly connected to the outer side of the winding drum, and a clamping gap for the filter bag to be squeezed into is formed between the clamping rod and the cylinder surface of the winding drum. After the filter bag is squeezed into the clamping gap, the spring expansion ring at the end of the filter bag is clamped and fixed to the clamping rod.
[0005] As a preferred technical solution, a protective cover is installed on the outer peripheral side of the coupling.
[0006] As a preferred technical solution, the clamping gap is 3 to 8 cm.
[0007] As a preferred technical solution, the outer end portion of the clamping rod is located inside the outer end portion of the winding drum.
[0008] Due to the adoption of the above technical scheme, the utility model has at least the following beneficial effects: when removing and extracting the waste filter bag from the dust collector flower plate, the filter bag is first manually drawn upward to make the spring expansion ring at the end of the filter bag separate from the dust collector flower plate, and then the bag body of the end part of the filter bag is squeezed into the clamping gap between the clamping rod and the winding drum. When the bag body of the end part of the filter bag is squeezed into the clamping gap, the spring expansion ring at the end of the filter bag is naturally clamped and fixed with the clamping rod. Then the reduction motor is started, and the reduction motor drives the winding drum and the clamping rod to rotate. Under the action of the winding drum and the clamping rod, the filter bag is gradually drawn upward from the dust collector flower plate and wound onto the winding drum. Finally, the filter bag that is completely extracted into a roll can be drawn from the winding drum. In this way, the waste filter bag can be quickly extracted instead of manually, which is convenient, fast, time-saving and labor-saving, and can greatly improve the removal efficiency and reduce the labor intensity of workers.

[0014] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0015] like Figure 1 and Figure 2As shown, the bag filter removal device of the bag filter includes a support seat 1 and a winding drum 2. A reduction motor 3 is installed on the support seat 1. The output end of the reduction motor 3 is connected to the winding drum 2 through a coupling 4. The drum shaft of the winding drum 2 is welded and fixed to the coupling 4, so that the reduction motor 3 can drive the winding drum 2 to rotate; a clamping rod 5 is fixedly connected to the outer side of the winding drum 2, and a clamping gap 6 for the filter bag 9 to squeeze in is formed between the clamping rod 5 and the cylinder surface of the winding drum 2. When the filter bag 9 squeezes into the clamping gap 6, the spring expansion ring 7 at the end of the filter bag 9 and the clamping rod 5 are naturally clamped and fixed. The width H of the clamping gap 6 is preferably 3 to 8 cm, so that on the one hand, the filter bag 9 can be smoothly squeezed in, and on the other hand, the roll diameter of the filter bag when it is rolled can be minimized.
[0016] refer to Figure 1 A protective cover 8 is installed on the outer peripheral side of the coupling 4 to improve the safety of the motor when it is working.
[0017] Preferably, the outer end position A of the clamping rod 5 is located on the inner side of the outer end B of the winding drum 2, so as to reduce the axial resistance of the clamping rod 5 to the rolled filter bag, making it easier to extract and peel the rolled filter bag off the winding drum 2.
[0018] refer to Figures 2 to 4 When the bag cage in the waste filter bag is extracted and the waste filter bag 9 needs to be removed from the dust collector plate 10, the filter bag 9 is first manually pulled upward to make the spring expansion ring 7 at the end of the filter bag 9 separate from the dust collector plate 10, and then the end part of the bag body of the filter bag 9 is squeezed into the clamping gap 6 between the clamping rod 5 and the winding drum 2. When the end part of the bag body of the filter bag is squeezed into the clamping gap 6, the spring expansion ring 7 at the end of the filter bag 9 is naturally clamped and fixed with the clamping rod 5, and then the reduction motor 3 is started. The reduction motor 3 drives the winding drum 2 and the clamping rod 5 to rotate. Under the joint action of the winding drum 2 and the clamping rod 5, the filter bag 9 is gradually pulled upward from the dust collector plate 10 and wound around the winding drum 2. Finally, the completely extracted rolled filter bag 9 can be pulled down from the winding drum 2. After extracting one filter bag, use the same method to extract the next one. This can achieve the rapid extraction of batches of waste filter bags. It is convenient, fast, saves time and effort, and can greatly improve the removal efficiency, reduce the labor intensity of workers, reduce dust, and is safe and environmentally friendly.
[0019] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
