Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a dust collection mechanism for a baghouse dust collector. Background Technology

[0002] A baghouse dust collector is a device used in industrial production to filter and remove dust from gases containing dust. It works by using filter bags to trap dust particles on the surface of the bags, thus purifying the gas. This equipment consists of components such as filter bags, frames, and a cleaning system. Different models of baghouse dust collectors have different components. It primarily works by changing the flow direction and velocity of the dust-laden gas, causing dust particles to be captured by the filter bags under the influence of inertia and gravity.

[0003] However, existing baghouse dust collectors have some problems when cleaning accumulated dust. When the dust reaches a certain level, cleaning is necessary to restore the filtration performance of the bags. However, current cleaning methods often lead to dust dispersion. During the cleaning process, dust is shaken off the bags, but due to a lack of effective collection and control measures, this dust disperses with the airflow. This dispersed dust not only re-enters the equipment, reducing dust removal efficiency, but may also permeate the workshop, affecting the normal operation of other equipment and even posing a health hazard to workers.

[0004] Therefore, it is necessary to design a dust collection mechanism for baghouse dust collectors that is practical and easy to collect accumulated dust to prevent it from scattering. Utility Model Content

[0005] The purpose of this utility model is to provide a dust collection mechanism for a bag filter to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dust collection mechanism for a bag filter, comprising a filter housing, characterized in that: a filter assembly is fixedly connected to the filter housing, the filter assembly includes a vortex shell, the vortex shell is fixedly connected to the inner top of the filter housing, a tangential hole is opened on the surface of the vortex shell, an outer cage is slidably connected inside the vortex shell, and a spiral column is slidably connected inside the outer cage.

[0007] According to the above technical solution, the spiral column includes a spiral disk, a support column is fixedly connected inside the spiral disk, a blocking disk is fixedly connected to the rear end of the support column, the blocking disk is slidably connected to the outer cage, and a thread is provided at the end of the support column, the thread being behind the blocking disk.

[0008] According to the above technical solution, a ventilation assembly is connected to the flange on the filter housing. The ventilation assembly includes a volute, which is connected to the flange on the filter housing. A dust collection groove is provided on the lower surface of the protruding left side of the volute.

[0009] According to the above technical solution, a threaded groove is provided on the left surface of the protrusion on the left side of the volute. The threaded grooves are arranged in sequence as a front empty groove, a second thread, and a rear empty groove.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-8 The present invention provides a technical solution: a dust collection mechanism for a bag filter, including a filter housing 1, a filter assembly 2 fixedly connected to the filter housing 1, the filter assembly 2 including a vortex shell 22, the vortex shell 22 being fixedly connected to the inner top of the filter housing 1, a tangential hole 221 being opened on the surface of the vortex shell 22, an outer cage 21 being slidably connected inside the vortex shell 22, and a spiral column 23 being slidably connected inside the outer cage 21.

[0015] The spiral column 23 includes a spiral disk 232, a support column 231 is fixedly connected inside the spiral disk 232, a blocking disk 233 is fixedly connected to the rear end of the support column 231, the blocking disk 233 is slidably connected to the outer cage 21, and a thread 234 is opened at the end of the support column 231, which is behind the blocking disk 233.

[0016] A ventilation assembly 3 is connected to the flange on the filter housing 1. The ventilation assembly 3 includes a volute 31, which is connected to the flange on the filter housing 1. A dust collection groove 32 is provided on the lower surface of the left protrusion of the volute 31, and a threaded groove 33 is provided on the left surface of the left protrusion of the volute 31. The threaded grooves 33 are arranged in sequence as a front empty groove 331, a second thread 332, and a rear empty groove 333. The lengths of the front empty groove 331, the second thread 332, the rear empty groove 333, and the first thread 234 are the same.

[0017] The ventilation component 3 is fixedly connected to the left side of the slide rail groove 34. The slide rail groove 34 is slidably connected to the motor 35. The output end of the motor 35 is fixedly connected to the end of the support column 231. The left end of the thread 234 on the support column 231 is exactly connected to the right end of the thread 332 on the volute 31.

[0018] Working principle: The filter bag is placed inside the outer cage 21 and fixed. The spiral column 23 is placed inside and opened up, and then placed inside the vortex shell 22. The flange of the ventilation component 3 is sealed. When air filtration is required, the motor 35 rotates in reverse. With the cooperation of thread 1 234 and thread 2 332, the spiral column 23 is pushed forward, causing the baffle plate 233 to block the dust collection groove 32 and seal the rear end of the ventilation component 3. The air to be treated is introduced into the volute 31 from the input end. The air source can be an air compressor. The air passes through the vortex shell 22 to form a cyclone and moves to the right along the support column 231. Through the filter bag supported on the surface of the spiral column 23, the impurities in the air are intercepted by the filter bag, thus filtering the air.

[0019] When the filter bag needs cleaning, the motor 35 rotates forward. With the threaded engagement of thread 234 and thread 332, it drives the spiral column 23 to move backward, causing the blocking disc 233 to leave the dust collection trough 32. The dust collection trough 32 is connected to the outside. The motor 35 continues to rotate forward. With the engagement of thread 332 and the rear empty groove 333, the support column 231 keeps spinning freely when the blocking disc 233 reaches behind the dust collection trough 32. The spiral column 23 continues to rotate and does not continue to move, driving the spiral disc 232 to cut the dust accumulated on the surface of the filter bag. At the same time, the volute 31 draws air outward. The outside air flows in through the tangential hole 221 on the surface of the vortex shell 22. With the engagement of the tangential hole 221 and the spiral disc 232, a vortex is formed to prevent the dust from escaping. When the vortex encounters the blocking disc 233, it is blocked and falls from the dust collection trough 32, achieving the purpose of dust collection and preventing escaping.
