Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to an explosion-proof bag dust collector. Background Art

[0002] The dust bag is the heart of a bag-type dust collector and is generally called a dust bag or dust filter bag. The dust bag is a key part of the operation of a bag-type dust collector. Usually, a cylindrical filter bag is hung vertically in the dust collector. The fabric and design of the dust bag should strive for high-efficiency filtration, easy dust removal and durability. However, after long-term use, dust will be adsorbed on the surface of the bag. Only most of the dust will be removed by recoil, while some tightly adhered dust is difficult to recoil. For this reason, an explosion-proof bag dust collector is proposed. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] To this end, the technical solution adopted in this utility model is:

[0005] A kind of explosion-proof bag dust collector comprises a main shell, an ash discharger arranged at the bottom of the main shell, an air inlet installed at the front end of the main shell, a clean air bin fixedly installed on the top of the main shell, and a clean air discharge port opened at one end of the clean air bin, a dust bag is installed on the top of the main shell, a recoil pipe is fixedly installed on the inner wall of the clean air bin, a branch pipe is connected to the recoil pipe, and the bottom end of the branch pipe is connected to a recoil head, a motor is installed on the top of the clean air bin, a half-tooth gear is connected to the output shaft of the motor, a reciprocating plate is meshed with the half-tooth gear, and the upper and lower sides of the reciprocating plate are slidably connected with a limit plate, and the two ends of the reciprocating plate are fixedly connected with a connecting rod, and the end of the connecting rod is connected with a fixed joint, the bottom of the fixed joint is connected with a connecting plate, and the two ends of the connecting plate are connected with a flapping plate.

[0006] Preferably, a solenoid valve is provided on the recoil head, and the bottom end of the recoil head penetrates into the dust removal bag.

[0007] Preferably, a bracket is connected to the bottom of the limiting plate, and the bottom end of the bracket is fixedly mounted on the inner wall of the main body shell.

[0008] Preferably, sliders are fixedly mounted on the upper and lower sides of the reciprocating plate, a sliding groove fitting the slider is provided on the limiting plate, and the slider is slidably connected in the sliding groove.

[0009] Preferably, the number of the flapping plates is six groups of twelve, which matches the number of dust bags, and the distance between the flapping plates in a group is greater than the diameter of the dust bags.

[0010] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0011] In the utility model, a reciprocating plate is arranged in the middle position of multiple groups of dust bags, and a motor is used to drive the half-tooth gear to rotate. Therefore, the reciprocating plate meshing with the half-tooth gear will start to reciprocate as the half-tooth gear rotates. This is the power basis for the flapping plate to reciprocate and hit the dust bags. For this purpose, the flapping plate is connected to the reciprocating plate through a connecting rod and a connecting plate. Therefore, the flapping plate obtains the same running route as the reciprocating plate, thereby completing the hitting of the surface of the dust bag, realizing dust removal, and improving the practicability of the device.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] An explosion-proof bag dust collector provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0018] Example:

[0019] Combination Figure 1-2As shown, the utility model provides an explosion-proof bag dust collector, including a main body shell 101, a dust discharger 102 arranged at the bottom of the main body shell 101, an air inlet 103 installed at the front end of the main body shell 101, a clean air bin 105 fixedly installed on the top of the main body shell 101, and a clean air discharge port 109 opened at one end of the clean air bin 105. A dust bag 104 is installed on the top of the main body shell 101, a recoil pipe 106 is fixedly installed on the inner wall of the clean air bin 105, a branch pipe 107 is connected to the recoil pipe 106, and a recoil head 108 is connected to the bottom end of the branch pipe 107. The recoil head 108 is provided with a solenoid valve, and the bottom end of the recoil head 108 extends deep into the dust bag 104, and a motor 110 is installed on the top of the clean air bin 105. A half-tooth gear 111 is connected to the output shaft of the motor 110. The half-tooth gear 111 A reciprocating plate 112 is meshed, and the upper and lower sides of the reciprocating plate 112 are slidably connected with a limit plate 114. Slide blocks 113 are fixedly installed on the upper and lower sides of the reciprocating plate 112. A slide groove 115 that fits the slide block 113 is opened on the limit plate 114, and the slide block 113 is slidably connected in the slide groove 115. The bottom of the limit plate 114 is connected with a bracket 1141, and the bottom end of the bracket 1141 is fixedly installed on the inner wall of the main shell 101. The two ends of the reciprocating plate 112 are fixedly connected with a connecting rod 116, and the end of the connecting rod 116 is connected with a fixed joint 117. The bottom of the fixed joint 117 is connected with a connecting plate 118, and the two ends of the connecting plate 118 are connected with flapping plates 119. The number of flapping plates 119 is six groups of twelve, which matches the number of dust bags 104, and the distance between a group of flapping plates 119 is greater than the diameter value of the dust bag 104.

[0020] Specifically, the position of the reciprocating plate 112 is clamped by the limiting plate 114 so that it will not deviate during operation, thereby ensuring the uniformity of the striking of the flapping plate 119, thereby removing the dust firmly adhered to the dust bag 104, thereby extending the service life of the device and improving the practicability of the device.

[0021] The working principle and use process of the utility model are as follows: first, the air inlet 103 is connected to the smoke exhaust pipe, and then the device is started, and the smoke is filtered by the dust bag 104, and the purified air is discharged to the outside from the clean air exhaust port 109;

[0022] When the dust bag 104 has a large resistance to filtration, the electromagnetic backwash on the backwash head 108 is turned on, and the backwashing gas is connected to the backwashing pipe 106 to backwash the dust bag 104 to clean the dust on the dust bag 104. After cleaning, the dust bag 104 can continue to be used for filtering and dust removal;

[0023] When the recoil of the recoil head 108 makes it difficult to remove the dust on the dust bag 104, the starter motor 110 drives the half-tooth gear 111 to rotate, so that the reciprocating plate 112 meshing with the half-tooth gear 111 will reciprocate, and thus the flapping plate 119 fixedly connected to the reciprocating plate 112 will run synchronously, thereby hitting the dust bag 104 during the operation to remove the dust adhered thereto, and finally the device can be maintained regularly.

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
