Description

Technical Field

[0001] This utility model relates to the field of dust collectors, and in particular to a pulse dust collector with a negative pressure filtration structure. Background Technology

[0002] A dust collector is a device used to remove dust, particulate matter, and harmful gases generated during industrial production. A pulse dust collector with a negative pressure filtration structure refers to a dust collector that uses negative pressure design and pulse cleaning technology to ensure dust removal effect and operational stability. It uses a fan in conjunction with the dust chamber to generate negative pressure, and uses pulsed compressed air to periodically blow away the dust on the filter bags.

[0003] Existing technologies, such as the utility model patent with publication number CN205796791U, disclose a pulse bag filter dust collector. This patent employs a housing, a support frame, and a pulse cleaning system. The housing contains multiple filter bags, is mounted on the support frame, and has multiple dust collectors below it. Multiple partitions divide the housing into independent filter chambers. A common clean air chamber is located above the filter chambers, with its outlet on the housing. Each filter chamber corresponds to a dust collector. Each independent filter chamber has a lifting valve above it to connect and disconnect the clean air chamber and the dust collection chamber. A flue gas inlet is located on the housing and connects to the dust collectors below each independent filter chamber via branch pipes. These branch pipes are equipped with flue gas shut-off valves. By installing flue gas shut-off valves at the flue gas inlet of each chamber, these valves are closed before cleaning, ensuring the entire filter chamber and clean air chamber are under the same negative pressure. This reduces the need for greater thrust and pull force when opening and closing the lifting valves, protecting the cylinders.

[0004] The inventors discovered the following problems in the use of dust collectors during their daily work: the lack of a primary filtration structure allows large debris to enter the dust collection equipment, which can easily cause equipment failure, increase maintenance difficulty, lead to long downtime, and reduce work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of a primary filter structure, high maintenance difficulty, long downtime, and reduced work efficiency.

[0006] To solve the above technical problems, this utility model provides a pulse dust collector with a negative pressure filtration structure, comprising: a frame and an adjustment structure. A dust collection chamber is installed on the inner wall of the frame, and a bag filter is installed on the inner wall of the dust collection chamber. A clean air chamber is provided on the upper surface of the dust collection chamber. Several pulse valves are installed on one side of the clean air chamber corresponding to the position of the bag filter. An induced draft device is installed on one side of the clean air chamber. An air inlet pipe is installed on one side of the dust collection chamber via the adjustment structure. An adjustment structure is provided on the side of the dust collection chamber near the air inlet pipe. The adjustment structure includes a connecting box, which is fixedly connected to the dust collection chamber. The connecting box is fixedly connected to the air inlet pipe on the side away from the dust filter chamber. A rectangular frame is slidably connected to the inner wall of the connecting box. Two supports and two filter screens are fixedly connected to the inner wall of the rectangular frame. Several sealing rings are fixedly connected to the surface of the rectangular frame. Fixing frames are fixedly connected to both sides of the rectangular frame. Two positioning blocks are fixedly connected to the arc surface of the fixing frames. A positioning frame is fixedly connected to the upper surface of the connecting box. A positioning rod is slidably connected to the inner wall of the positioning frame. The arc surface of the positioning rod is slidably connected to the positioning block. A spring is sleeved on the arc surface of the positioning rod. The two ends of the spring are fixedly connected to the positioning frame and the positioning rod, respectively.

[0007] The above components achieve the following effects: they use filters to perform preliminary filtration of large-volume debris; the two filters on the rectangular frame can work alternately, reducing downtime and maintenance difficulty, and improving production efficiency.

[0008] Preferably, two storage slots are provided on the inner wall of the rectangular frame corresponding to the position of the filter screen.

[0009] The effect achieved by the above components is to collect debris that has not passed through the filter using a collection slot, providing convenience for maintenance personnel.

[0010] Preferably, the lower end of the positioning rod is arc-shaped.

[0011] The effect achieved by the above components is that the lower end of the positioning rod is arc-shaped, which makes it easier for the positioning rod to slide into the positioning block.

[0012] Preferably, a pull ring is rotatably connected to the upper end of the positioning rod.

[0013] The effect achieved by the above components is that the operating pull ring drives the positioning rod to move, making it convenient for the user to move the positioning rod.

[0014] Preferably, the connecting box has an auxiliary structure on the side away from the dust filter chamber. The auxiliary structure includes a support plate, which is fixedly connected to the connecting box. Two support rods are slidably connected to the inner wall of the support plate. Both ends of the two support rods are fixedly connected to a connecting plate. An installation rod is fixedly connected to the side of the two connecting plates that are close to each other. Several hooks are fixedly connected to the surface of the installation rod.

[0015] The effects achieved by the above components are: the position of the hook can be flexibly adjusted, making it convenient for users to perform high-altitude operations according to the position of the rectangular frame, increasing the working range, reducing the difficulty of operation when working at height, and improving the safety of operation.

[0016] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the inner wall of the hook.

[0017] The effect achieved by the above components is to increase the friction of the inner wall of the hook through the anti-slip pad, so that the hook and the escalator can be better engaged.

[0018] Preferably, a limiting rod is threadedly inserted into the upper surface of the support plate at the position corresponding to the support rod.

[0019] The effect achieved by the above components is that when the limiting rod is rotated, the limiting rod presses down on the support rod with the help of the threads, thereby improving the safety of operation.

[0020] Compared with related technologies, the pulse dust collector with a negative pressure filtration structure provided by this utility model has the following beneficial effects:

[0021] This utility model provides a pulse dust collector with a negative pressure filtration structure. By setting an adjustment structure, it uses a filter screen to perform preliminary filtration of large-volume debris. The operation of the positioning rod can release the limit on the fixed frame, and the horizontal movement of the fixed frame can adjust the position of the rectangular frame. The two filters on the rectangular frame can work alternately, which can reduce downtime and maintenance difficulty, and improve production efficiency.

[0022] By setting up an auxiliary structure, hooks are used in conjunction with ladders for operation. The position of the hooks can be flexibly adjusted, making it convenient for users to climb the ladder according to the position of the rectangular frame, increasing the working range, reducing the difficulty of operation when climbing, and improving the safety of operation.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 4 This utility model provides a pulse dust collector with a negative pressure filtration structure, comprising: a frame 1 and an adjustment structure 7. A dust filter chamber 2 is installed on the inner wall of the frame 1, and a bag filter is installed on the inner wall of the dust filter chamber 2. A clean air chamber 3 is provided on the upper surface of the dust filter chamber 2. Several pulse valves 4 are installed on one side of the clean air chamber 3 corresponding to the position of the bag filter. An exhaust fan 5 is installed on one side of the clean air chamber 3. An air inlet pipe 6 is installed on one side of the dust filter chamber 2 through the adjustment structure 7. The adjustment structure 7 is provided on the side of the dust filter chamber 2 near the air inlet pipe 6. An auxiliary structure 8 is provided on the side of the connecting box 701 away from the dust filter chamber 2.

[0031] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjusting structure 7 includes a connecting box 701, which is fixedly connected to the dust filter chamber 2. The side of the connecting box 701 away from the dust filter chamber 2 is fixedly connected to the air inlet pipe 6. A rectangular frame 702 is slidably connected to the inner wall of the connecting box 701. Two supports 703 and two filter screens 704 are fixedly connected to the inner wall of the rectangular frame 702. Several sealing rings 705 are fixedly connected to the surface of the rectangular frame 702. Fixing frames 707 are fixedly connected to both sides of the rectangular frame 702. Two positioning blocks 708 are fixedly connected to the arc surface of the fixing frame 707. A positioning frame 709 is fixedly connected to the upper surface of the connecting box 701. A positioning rod 710 is slidably connected to the inner wall of the positioning frame 709. The arc surface of the positioning rod 710 is slidably connected to the positioning block 708. A spring 711 is fitted onto the arc surface of the positioning rod 710. The two ends of the spring 711 are fixedly connected to the positioning frame 709 and the positioning rod 710 respectively. The filter screen 704 is used to perform preliminary filtration of large-volume debris. The two filters 704 on the rectangular frame 702 can work alternately to reduce downtime and maintenance difficulty and improve production efficiency. Two collection slots 706 are opened on the inner wall of the rectangular frame 702 corresponding to the position of the filter screen 704. The collection slots 706 are used to collect debris that has not passed through the filter screen 704, providing convenience for maintenance personnel. The lower end of the positioning rod 710 is arc-shaped, which makes it easy for the positioning rod 710 to slide into the positioning block 708. The upper end of the positioning rod 710 is rotatably connected to the pull ring 712. Operating the pull ring 712 drives the positioning rod 710 to move, which is convenient for the user to move the positioning rod 710.

[0032] In the embodiments of this utility model, please refer to Figure 4 The auxiliary structure 8 includes a support plate 81, which is fixedly connected to the connecting box 701. Two support rods 82 are slidably connected to the inner wall of the support plate 81. Both ends of the two support rods 82 are fixedly connected to the connecting plates 83. An installation rod 84 is fixedly connected to the side of the two connecting plates 83 that is close to each other. Several hooks 85 are fixedly connected to the surface of the installation rod 84. The position of the hooks 85 can be flexibly adjusted to facilitate users to perform high-altitude operations according to the position of the rectangular frame 702, thereby increasing the working range, reducing the difficulty of operation when working at height, and improving the safety of operation. An anti-slip pad 86 is fixedly connected to the inner wall of the hook 85. The anti-slip pad 86 is a rubber pad. The anti-slip pad 86 increases the friction of the inner wall of the hook 85, making the hook 85 better engaged with the ladder. A limiting rod 87 is threadedly inserted on the upper surface of the support plate 81 at the position corresponding to the support rod 82. When the limiting rod 87 is rotated, the limiting rod 87 presses the support rod 82 downward with the thread, thereby improving the safety of operation.

[0033] The working principle of the pulse dust collector with negative pressure filtration structure provided by this utility model is as follows: By setting the adjustment structure 7, the positioning rod 710 is first moved away from the positioning frame 709. The positioning rod 710 moves upward away from the positioning block 708, and the spring 711 is in a stretched state, releasing the limitation on the fixed frame 707. At this time, the fixed frame 707 can be moved laterally. Observe the positional relationship between the filter screen 704 to be used on the rectangular frame 702 and the connecting box 701. Then, the fixed frame 707 is moved, and the fixed frame 707 drives the rectangular frame 702 to move along the inner wall of the connecting box 701, so that the filter screen 704 to be used moves into the connecting box 701, and at the same time, the other filter screen 704 moves out of the connecting box 701. After the positioning rod 710 is aligned with the positioning block 708 at the corresponding position, the positioning rod 710 is released. Under the elastic force of the spring 711, the positioning rod 710 moves towards the positioning frame 709 and slides down into the positioning block 708, fixing the position of the fixing frame 707. At this time, the filter screen 704, which has been removed from the connecting box 701, can be maintained as a whole. The positioning frame 709 on the rectangular frame 702 supports the filter screen 704, making the filter screen 704 protrude at a certain angle. The sealing ring 705 increases the airtightness between the rectangular frame 702 and the connecting box 701. The collection groove 706 collects the debris that has not passed through the filter screen 704, providing convenience for maintenance personnel. The lower end of the positioning rod 710 is arc-shaped, which makes it easy for the positioning rod 710 to slide into the positioning block 708. The operating pull ring 712 drives the positioning rod 710 to move, making it easy for the user to move the positioning rod 710.

[0034] By setting up auxiliary structure 8, first observe the positional relationship between rectangular frame 702 and connecting box 701. Then, operate the escalator to move the connecting plate 83 laterally. The connecting plate 83 drives the two support rods 82 to slide along the support plate 81. During this process, the support plate 81 drives the hook 85 to move through the mounting rod 84, so that the hook 85 is in the appropriate position of the connecting box 701. Then, operate the upper end of the escalator to lock in the hook 85. After the user climbs up the escalator, they should first rotate the limit rod 87. After the limit rod 87 squeezes the support rod 82, the subsequent operation can be carried out. Before climbing down the escalator, the limit rod 87 should be reversed to release the limit on the support rod 82. The anti-slip pad 86 increases the friction of the inner wall of the hook 85, making the hook 85 and the escalator lock better. Rotate the limit rod 87, and the limit rod 87 squeezes the support rod 82 downward with the help of the thread, improving the safety of operation.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
