Description

Technical Field

[0001] This utility model belongs to the field of dust collector technology, specifically relating to a rapid dust collector bag knocking dust collector and dust removal system. Background Technology

[0002] During dust collector bag replacement, dust accumulation on the outside of the bags and adhesion between the filter ribs and the bags have been two major challenges causing environmental degradation and limiting the speed of bag replacement. Dust accumulation on the outside of the bags cannot be completely removed with pulse air pressure; some dust detaches from the original air chamber during replacement, creating dust on-site and severely deteriorating the working environment. When the filter bags adhere to the filter ribs, the weight of the ribs and bags, as well as the friction between the bags and the tube sheet opening, makes lifting difficult. Currently, due to limited space above the dust collector chamber and the length of the filter ribs, automated equipment cannot be used to replace the bags. Only two people can lift them, and then separate them with blades or similar tools, increasing labor intensity and severely limiting the speed of bag replacement.

[0003] Chinese patent document CN212818922U (202021362514.9) discloses a dust removal device in the zinc powder production process. This device utilizes a centrifugal motion of dust removal balls relative to a dust removal rod, causing the dust removal balls to contact the dust collector bag and dislodge dust from the bag. However, the internal frame of the dust collector bag has a mesh structure, making it easy for the dust removal balls to get stuck. Therefore, this dust removal device cannot be used to remove dust from the frame, and its fixed position inside the bag hinders normal ventilation. Utility Model Content

[0004] The main purpose of this utility model is to provide a rapid dust collector bag knocking dust collector and dust removal system to solve the problems of environmental degradation during the replacement process caused by dust accumulation on the outside of the bag, and increased labor intensity and slow replacement speed caused by the adhesion of the bag frame.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a rapid dust removal bag knocking dust collector, including a rotating bracket, a flexible dust removal belt and a rotating drive device;

[0006] The flexible dust removal belt is installed at the lower end of the rotating support, and the upper end of the rotating support is connected to the rotating drive device.

[0007] The rotary drive device is used to drive the rotary support to rotate.

[0008] In a preferred embodiment of this invention, the rotating bracket includes a connecting rod and a fixing flange;

[0009] The fixed flange is coaxially mounted at the lower end of the connecting rod, and the upper end of the flexible dust collection belt is fixed to the edge of the fixed flange. By positioning the upper end of the flexible dust collection belt at the edge of the fixed flange, it is easier to swing the flexible dust collection belt up during the rotation of the fixed flange, thus enhancing the impact effect.

[0010] In a preferred embodiment of this invention, multiple flexible dust removal belts are arranged along the circumference of the fixed flange to improve the hammering effect and increase dust removal efficiency.

[0011] Preferably, this utility model also includes a telescopic rod, which is located between the rotating bracket and the rotating drive device, and is detachably connected to both the rotating bracket and the rotating drive device. To better adapt to the site environment and for ease of operation, the telescopic rod allows for tapping of keels at different heights, ensuring effective dust removal and sufficient vibration force at different heights of the keels.

[0012] Preferably, the rotary drive device of this invention is a handheld motor or an electric wrench. A handheld motor or electric wrench facilitates manual operation by the operator, and the electric wrench can be quickly connected to the lower rotary support via a quick-connect coupling.

[0013] Preferably, this invention also includes a connecting ring. The fixed flange has a connecting hole, and the upper end of the flexible dust collector belt is connected to the connecting hole via the connecting ring. Using the connecting ring to connect the flexible dust collector belt to the connecting hole of the fixed flange facilitates the installation and replacement of the flexible dust collector belt. When the flexible dust collector belt is damaged, a new one can be quickly replaced.

[0014] Preferably, the flexible dust removal belt of this invention is a rubber belt. Rubber belts have good tensile strength and elasticity, and are not easily damaged.

[0015] This utility model also discloses a rapid dust removal bag knocking dust removal system, which utilizes the above-mentioned rapid dust removal bag knocking dust removal device, including a bag dust collector, the bag dust collector including a dust collection chamber and a tube sheet, dust collection bags and a keel arranged in the dust collection chamber;

[0016] The tube sheet is provided with an air inlet hole, the upper end of the dust collector bag is connected to the air inlet hole, and the keel is set inside the dust collector bag;

[0017] The lower end of the rotating bracket extends into the dust collector bag. By inserting the lower end of the rotating bracket of the quick dust collector bag tapping dust remover into the dust collector bag, the accumulated dust on the keel and the keel can be effectively removed and the bag can be separated.

[0018] Preferably, this invention also includes a negative pressure fan, which is connected to the exhaust channel of the dust collection chamber. Under the action of the negative pressure fan, a negative pressure is generated in the dust collection chamber. The dust accumulated during the knocking process does not generate dust under the action of negative pressure, and the dust accumulation is reduced during the replacement of filter bags, which helps to improve the on-site operating environment and reduce the amount of dust inhaled by operators.

[0019] Preferably, in this invention, the width of the flexible dust removal belt is greater than or equal to the mesh width of the keel, which can effectively prevent the flexible dust removal belt from getting stuck in the mesh of the keel.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The quick dust removal bag knocking dust collector of this utility model has a flexible dust removal belt set at the lower end of the rotating support, and the upper end of the rotating support is connected to the rotating drive device. The rotating drive device drives the rotating support to rotate, thereby causing the flexible dust removal belt below to swing around the rotation center and beat the keel. Thus, the vibration of the keel causes the bag to vibrate, which promotes the falling of accumulated dust and the separation of the keel from the bag.

[0021] Replacing manual pulling and knocking of dust-adhesive bags with a rotary drive device helps reduce the labor intensity of operators. Attached Figure Description
