Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust collector using a bag filter. Background Technology

[0002] Baghouse dust collectors are a widely used and highly efficient air purification device in industrial production. They purify the gas by guiding dust-laden gas through filter bags, intercepting and collecting dust particles. However, as the equipment operates for longer periods, dust accumulates on the surface of the filter bags, forming a dust layer. This significantly increases airflow resistance and reduces the system's processing capacity and purification efficiency.

[0003] To maintain the stable and efficient operation of a dust collector, the dust accumulated on the surface of the filter bags must be periodically cleaned; this process is called dust removal. Among the many dust removal methods, mechanical vibration dust removal is widely used due to its relatively simple structure and low cost. This method typically uses a mechanical device to drive the filter bags or their suspension frame to vibrate or shake, using inertial force to dislodge the attached dust.

[0004] However, existing mechanical vibration cleaning devices still have shortcomings in practical applications. Some devices have relatively simple vibration mechanisms, resulting in significant energy loss during transmission to the filter bags. Alternatively, the vibration frequency and amplitude may not be ideally matched, leading to insufficient effective vibration force transmitted to the filter bags and incomplete cleaning. This incomplete cleaning causes some dust to remain deep within the filter bag fibers for extended periods, eventually leading to "bag clogging"—the filter bags become blocked by dust, permanently reducing air permeability. This not only severely impacts the long-term operational stability of the equipment but also significantly shortens the filter bag's lifespan and increases the company's maintenance costs.

[0005] Therefore, this utility model proposes a dust collector for smoke and dust to overcome the shortcomings of the prior art. Utility Model Content

[0026] 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.

[0027] Please refer to Figures 1 to 4 This utility model provides a dust collector for smoke and dust, which aims to solve the problems of low vibration efficiency of the dust removal mechanism of the existing bag dust collector, which leads to easy clogging of the filter bag, and the cumbersome installation and disassembly of the filter bag and inaccurate positioning.

[0028] The dust collector includes a support frame 1, with a railing 6 fixed to the top of the support frame 1. A housing 2 is fixed to the support frame 1, and an air inlet pipe 3 and an air outlet pipe 4 are provided on the housing 2. A fan 5 is connected to the air outlet pipe 4, and a filter bag body 701 for filtering gas is provided inside the housing 2.

[0029] The dust collector also includes a cleaning assembly 8 for vibrating and cleaning the filter bag body 701; the cleaning assembly 8 includes a motor 810, symmetrically arranged eccentric wheels 801, connecting rods 802, fixing blocks 803, a first spring 804, a sliding cylinder 806, a connecting box 805, a vibrating rod 808, a second spring 807, and a vibrating plate 809; in the cleaning assembly 8, the eccentric wheels 801 are driven to rotate by the motor 810, one end of the connecting rod 802 is rotatably connected to the eccentric wheels 801, and the other end of the connecting rod 802 is rotatably connected to the fixing block 803, thereby converting the rotational motion of the eccentric wheels 801 into the up-and-down reciprocating motion of the fixing block 803;

[0030] The sliding cylinder 806 is fixed inside the housing 2. The connecting box 805 is fixedly connected to the fixing block 803 and slidably fitted inside the sliding cylinder 806. The first spring 804, which is symmetrically arranged, is connected between the fixing block 803 and the sliding cylinder 806 to assist and stabilize the reciprocating motion.

[0031] The vibrating rod 808 is inserted into the connecting box 805 and can move axially relative to the connecting box 805. The vibrating rod 808 is provided with a stop block. The inner wall of the connecting box 805 is configured to abut against the stop block during the up-and-down reciprocating motion. One end of the second spring 807 is connected to the connecting box 805, and the other end of the second spring 807 is connected to the vibrating rod 808. Through the relative movement and impact between the connecting box 805 and the vibrating rod 808, the vibrating rod 808 is driven to generate high-frequency vibration.

[0032] The vibrating plate 809 is fixed to the top of the vibrating rod 808 and is connected to the upper part of the bag body 701, thereby transmitting the vibration of the vibrating rod 808 to the bag body 701 to achieve shaking dust removal.

[0033] The mounting assembly 7 includes a limiting box 705 fixed to the outer wall of the slide 704, a slide 704 and a limiting groove 707 opened on the limiting box 705, a limiting block 703 rotatably disposed in the limiting box 705, a limiting post 706 fixed to the bag body 701, and a nozzle 702 fixed to the top outlet of the bag body 701.

[0034] The limiting box 705 serves as the mounting base, the slide groove 704 provides the main sliding guide for the movement of the bag body 701, the limiting groove 707 provides the movement trajectory guide for the limiting post 706, and the limiting block 703 is designed as a component that can rotate around its pivot to hold or release the limiting post 706 at a specific position.

[0035] In the assembled state, the frame of the bag body 701 is slidably engaged in the groove 704 of the limiting box 705, while the limiting post 706 on the bag body 701 is slidably engaged in the limiting groove 707 of the limiting box 705; when the bag body 701 is fully pushed into the predetermined position, the limiting block 703 rotates to the locking position and holds the limiting post 706, thereby completing the installation and fixing of the bag body 701.

[0036] During disassembly, the locking block 703 can be unlocked by reversing the operation, and the bag body 701 can be pulled out along the slide groove 704.

[0037] This cooperative structure, which is guided by the slide groove 704 and locked by the limiting block 703 and the limiting post 706, ensures the ease of installation and the accuracy of positioning of the bag body 701.

[0038] Once the bag body 701 is installed in place, its top nozzle 702 connects with the air outlet pipe 4 to form a channel for the discharge of clean gas.

[0039] In a preferred embodiment, to further enhance the stability and rebound efficiency of the dust removal assembly 8, the dust removal assembly 8 also includes a symmetrically arranged first spring 804. The two ends of the first spring 804 are respectively connected between the fixed block 803 and the sliding cylinder 806. When the fixed block 803 drives the connecting box 805 to reciprocate, the first spring 804 undergoes elastic deformation, storing and releasing energy during the movement, thereby providing auxiliary force for the reverse movement of the connecting box 805, making the entire driving process more stable and efficient.

[0040] As another preferred embodiment, in order to achieve effective impact on the vibrating rod 808 to generate high-frequency vibration, the vibrating rod 808 is provided with an integrally formed stop block, and the inner wall of the connecting box 805 has an abutment surface corresponding to the stop block. During the reciprocating motion of the connecting box 805, the abutment surface of the inner wall of the connecting box 805 periodically impacts the stop block on the vibrating rod 808, and transmits the energy of the reciprocating motion to the vibrating rod 808 in an impact manner. This structural design ensures the efficient generation of vibration.

[0041] In a preferred embodiment, in order to effectively collect and export the clean gas filtered by the bag body 701, the mounting assembly 7 also includes a nozzle 702. The lower end of the nozzle 702 is fixed to the top outlet of the bag body 701, and the upper end of the nozzle 702 is connected to the air outlet 4. The nozzle 702 provides a sealed transition channel for the clean gas from the bag body 701 to the air outlet 4.

[0042] In a preferred embodiment, in order to provide the power for airflow to the entire dust removal system, a fan 5 is connected to the air outlet duct 4. The operation of the fan 5 generates negative pressure, which draws the dust-laden gas from the air inlet duct 3 into the housing 2 and discharges the filtered clean gas from the air outlet duct 4.

[0043] In a preferred embodiment, in order to provide stable support for the entire equipment and raise the main body of the equipment, the box 2 is fixed to the bracket 1 by welding or bolting. The bracket 1 is a steel structure frame, which reserves installation and operation space for the ash hopper below the equipment.

[0044] As a preferred embodiment, in order to ensure the safety of maintenance personnel when working at heights, a railing 6 is fixed around the top platform of the support 1.

[0045] Working principle: When filtering smoke and dust, the fan 5 starts and generates negative pressure in the housing 2. The dust-laden gas is drawn into the housing 2 through the inlet pipe 3. When the gas passes through the bag body 701, the dust is intercepted and adsorbed on the outer surface of the bag body 701, while the filtered clean gas enters the interior of the bag body 701 and is collected in the outlet pipe 4 through the spray pipe 702 which is fixedly connected to the top outlet of the bag body 701, and finally discharged by the fan 5.

[0046] When the dust adsorbed on the surface of the bag body 701 reaches a certain amount and needs to be cleaned, the dust removal component 8 starts working; the motor 810 drives the symmetrically arranged eccentric wheel 801 to rotate. Since one end of the connecting rod 802 is rotatably connected to the eccentric wheel 801 and the other end is rotatably connected to the fixed block 803, the rotational motion of the eccentric wheel 801 is converted into the up-and-down reciprocating linear motion of the fixed block 803; the connecting box 805, which is fixedly connected to the fixed block 803, slides in the sliding cylinder 806 fixed to the housing 2. During this process, the first spring connecting the fixed block 803 and the sliding cylinder 806... Spring 804 continuously extends and rebounds, stabilizing and assisting the movement. When the connecting box 805 moves up and down, the inner wall of the connecting box 805 moves relative to the vibrating rod 808 passing through the connecting box 805, and periodically impacts the stop block set on the vibrating rod 808. Under the synergistic action of the second spring 807, the vibrating rod 808 generates high-frequency vibration. This vibration is directly transmitted to the bag body 701 connected to the vibrating plate 809 fixedly connected to the top of the vibrating rod 808, causing the bag body 701 to shake violently, thereby shaking off the dust adsorbed on the surface.

[0047] When the bag body 701 needs to be cleaned or replaced, open the box 2 and manually rotate the limiting block 703 set in the limiting box 705 so that the limiting block 703 no longer jams the limiting post 706 on the bag body 701. At this time, the bag body 701 can be smoothly pulled out of the limiting box 705 by following the guide of the sliding groove 704 and the limiting groove 707 opened on the limiting box 705. During installation, push the new or cleaned bag body 701 inward along the sliding groove 704. When it reaches the predetermined position, the limiting post 706 will force the limiting block 703 to rotate and make room. After it is fully inserted, the limiting block 703 will automatically return to its original position under its own weight or elastic force, and re-jaw the limiting post 706, thus completing the quick and accurate installation and fixing.
