Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a pull-out type bag dust collector. Background Technique

[0002] A bag dust collector is a dry dust filtering device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified. However, the loading and unloading of the filter bags of the existing bag dust collectors are relatively difficult, thus reducing the maintenance efficiency of the bag dust collectors.

[0003] For example, a pull-out type bag dust collector with the patent document number CN220736828U includes a box body, a fan, and filter bags. The box body is connected to the fan, and the filter bags are connected inside the box body. A pull-out frame is slidably connected inside the box body, and a connection and positioning part for connecting the pull-out frame is installed inside the box body. An installation mechanism for detachably connecting the filter bags is installed inside the pull-out frame, and a dust transmission mechanism for receiving and conveying dust is arranged at the bottom of the box body. This utility model facilitates the replacement and maintenance of the filter bags through the pull-out frame that can be horizontally moved into and out of the box body. The filter bags are quickly disassembled and assembled through the installation mechanism. The dust treatment efficiency is improved through the dust transmission mechanism.

[0004] However, this structure has the following defects: one is that the box body needs to be completely pulled out to replace the filter bags, and each installation is relatively cumbersome; the other is that when the box body is pulled out in this pull-out structure, it is easy to fall off and cause injury to personnel. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pull-out type bag dust collector to solve the problems existing in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a pull-out type bag dust collector, including a fan 1 and a box body 8. A conveying cover 14 is arranged at the top of the box body 8 and is connected to the fan 1 through a pipeline 4. A pull-out frame 2 is arranged inside the box body 8, and a dust collector discharge port 19 and a dust loading box 20 are arranged below. The characteristics are as follows: Symmetrical translation and sinking mechanisms are arranged on both sides of the pull-out frame 2, including a guide plate 3, an auxiliary moving support plate 10, and a connecting rod one 6 and a connecting rod two 7 that are respectively hinged to the auxiliary moving support plate 10 and the pull-out frame 2. The connecting rod one 6 and the connecting rod two 7 are parallel, and the auxiliary moving support plate 10 can slide in the upper guiding grooves 9 on both sides of the top of the box body 8.

[0007] Preferably, the auxiliary moving support plate 10 is provided with a translation guiding groove 11, a downward movement guiding groove 17 and a fixing groove 18, which are arranged in sequence from top to bottom, and the translation guiding groove 11 and the fixing groove 18 are parallel to the upper guiding groove 9.

[0008] Preferably, both sides of the top of the pull-out frame 2 are provided with more than 2 load-bearing wheels 13, and the distance from the innermost load-bearing wheel 13 to the opening of the box body 8 is less than the length of the translation guiding groove 11.

[0009] Preferably, the connecting rod 1 6 is provided with a guiding wheel 5 that cooperates with the translation guiding groove 11.

[0010] Preferably, the sliding distance of the guiding wheel 5 on the translation guiding groove 11 is greater than the total length of the pull-out frame 2.

[0011] Preferably, the top of the pull-out frame 2 and the box body 8 are respectively provided with a pull-out frame air inlet 21 and a box body air inlet 22 that are coaxial with the filter cloth 12.

[0012] Preferably, the depth of the upper guiding groove 9 is equal to the thickness of the guiding plate 3.

[0013] Compared with the prior art, the beneficial effect of the present utility model is that for this pull-out structure, only by pulling the pull-out frame in place can it be ensured that the pull-out frame is outside the box body and below the box body, and the pull-out frame will not fall off, ensuring that the pull-out frame can enter and exit the box body along the guide every time, improving safety and the convenience of replacing the filter cloth.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-2 , the present invention provides a technical solution: a pull-out bag filter, which includes a fan 1 and a box body 8. A conveying cover 14 is provided at the top of the box body 8 and is connected to the fan 1 through a pipeline 4. A pull-out frame 2 is provided inside the box body 8, and a dust collector discharge port 19 and a dust loading box 20 are provided below. The pull-out frame 2 and the top of the box body 8 are respectively provided with a pull-out frame air inlet 21 and a box body air inlet 22 coaxial with the filter cloth 12, and the pull-out frame 2 is provided with an electric suction door 15 and a handle 16.

[0019] Symmetrical translation and sinking mechanisms are provided on both sides of the pull-out frame 2, which include a guide plate 3, an auxiliary moving support plate 10, and a connecting rod one 6 and a connecting rod two 7 respectively hinged to the auxiliary moving support plate 10 and the pull-out frame 2. The connecting rod one 6 and the connecting rod two 7 are parallel, and the auxiliary moving support plate 10 can slide in the upper guide grooves 9 on both sides of the top of the box body 8. The auxiliary moving support plate 10 is provided with a translation guide groove 11, a downward movement guide groove 17, and a fixing groove 18, which are arranged in sequence from top to bottom, and the translation guide groove 11 and the fixing groove 18 are parallel to the upper guide groove 9; both sides of the top of the pull-out frame 2 are provided with more than 2 load-bearing wheels 13, and the distance from the innermost load-bearing wheel 13 to the opening of the box body 8 is less than the length of the translation guide groove 11; a guide wheel 5 is provided on the connecting rod one 6; the sliding distance of the guide wheel 5 on the translation guide groove 11 is greater than the total length of the pull-out frame 2, and the depth of the upper guide groove 9 is equal to the thickness of the guide plate 3.

[0020] The specific working principle is as follows:

[0021] When the handle 16 is pulled, the pull-out frame 2 moves along the directions of the translation guide groove 11 and the upper guide groove 9. Since the travel of the load-bearing wheels 13 and the total length of the pull-out frame 2 are less than the walking length of the guide wheel 5 on the translation guide groove 11, the pull-out frame 2 is outside the box body 8. Then the guide wheel 5 passes through the downward movement guide groove 17, which will drive the pull-out frame 2 to move downward. Finally, the guide wheel 5 stops moving at the fixing groove 18. At this time, the pull-out frame 2 is below the right side of the box body 8, which is convenient for replacing the filter cloth 12. After the replacement is completed, the pull-out frame 2 is pushed to move in the opposite direction and enter the box body 8.

[0022] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
