Technical Field
[0001] This utility model belongs to the technical field of dust removal equipment, specifically, it relates to an industrial dust collector with a multi-layer filtration structure. Background Technology
[0002] Industrial dust collectors, as indispensable environmental protection equipment in industrial production, are mainly used to remove dust and particulate matter from the air to ensure a clean working environment and the health of employees. Traditional industrial dust collectors typically use bag filter systems. Their working principle involves creating negative pressure inside the machine using a fan or air pump, drawing dust-laden air into the equipment. Impurities first undergo primary filtration through a non-woven fabric filter bag, then the air carrying fine dust undergoes secondary filtration through a specially designed filter, and finally, clean air is discharged from the exhaust vent. While this design achieves dust removal to some extent, its filtration method is relatively simple, relying mainly on physical interception, resulting in limited filtration efficiency, especially for capturing fine dust or particulate matter in high-humidity environments.
[0003] Chinese Patent No. CN 217431259 U discloses an industrial dust collector with a multi-layer filtration structure. The technical solution includes: a nozzle, a base plate, a circular cover, and a filter device. A first housing is fixed to one side of the base plate, and a second housing is fixed to the other side. The second housing has a circular groove, and a second holding groove is formed at the bottom of the circular groove. The filter device is inserted into the second holding groove. A suction device is fixed to the bottom of the second holding groove. A first pipe is fixed to one side of the outer wall of the second housing, and a bent pipe is fixed to the other side of the outer wall of the second housing. One side of the bent pipe is fixed to the first housing. The first housing has a circular hole, and the upper end of the outer wall of the nozzle extends into the circular hole and is fixed therein. A second pipe is fixed to the rear end of the first housing. This invention has the advantages of allowing filtration through different filtration methods, thus enhancing the filtration effect, and facilitating the replacement of the filter device.
[0004] However, in actual use, the filtration core of the aforementioned devices still relies on the filter bag material, resulting in a single filtration method that cannot adapt to complex dust compositions (such as oily dust or sticky particles). Dust accumulation can easily lead to a decrease in filtration efficiency. Secondly, the filter bags are prone to wear, blockage, or moisture absorption during long-term use, and the replacement process is cumbersome, requiring the disassembly of multiple mechanical parts (such as locking blocks and springs). This is not only time-consuming and labor-intensive but may also affect the equipment's sealing performance due to assembly errors, leading to the risk of secondary pollution. Finally, the overall structure lacks a modular design, requiring machine shutdown for maintenance, which affects production continuity. In view of this, this utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an industrial dust collector with a multi-layer filtration structure, thus solving the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An industrial dust collector with a multi-layer filtration structure includes: a dust collector main unit, mounting rails, filter plates, a water storage tank, and a wastewater tank. Both ends of the dust collector main unit are fixedly connected to interfaces. Two sets of mounting rails are provided, each fixedly connected to both sides of the inner wall of the dust collector main unit. The filter plates are snapped into the interior of the mounting rails. Two sets of filter plates are provided. The top of the dust collector main unit is fixedly connected to the water storage tank. A spray head is fixedly connected to the top wall of the dust collector main unit and connected to the water storage tank. The wastewater tank is located at the bottom of the dust collector main unit, directly below the spray head, and communicates with the inner cavity of the dust collector main unit. Support columns are fixedly connected to the four corners of the bottom of the dust collector main unit.
[0007] Optionally, a retaining strip is fixedly connected to the top of the filter plate, and a through groove is opened at the top of the dust collector main unit, which matches the model and specifications of the retaining strip.
[0008] Optionally, the mounting rail has a pressure strip inside, and a guide rod is fixedly connected to one side surface of the pressure strip. The guide rod is slidably inserted into the side wall of the mounting rail, and the other side surface of the pressure strip is tightly abutted against the edge of the filter plate.
[0009] Optionally, a spring is movably sleeved on the surface of the guide rod, one end of the spring abutting tightly against the surface of the pressure strip, and the other end of the spring abutting tightly against the inner wall of the mounting vertical rail.
[0010] Optionally, a pulse valve pipe is fixedly connected to the top of one side surface of the dust collector main unit, and two blow nozzles are fixedly connected to the pulse valve pipe through a pipe. The blow nozzles are located on one side of the top of the filter plate.
[0011] Optionally, the bottom of the dust collector main unit has two discharge troughs, which correspond to the bottom of the filter plate. Both sides of the discharge trough are fixedly connected to discharge troughs, and both sides of the discharge trough are fixedly connected to mounting rails. A material receiving channel is provided directly below the discharge trough, and the material receiving channel is slidably engaged with the mounting rails.
[0012] Optionally, two louvered grilles are fixedly connected to the inner wall of the dust collector main unit, and the two louvered grilles are arranged on both sides of the spray head.
[0013] Optionally, a discharge head is fixedly connected to one end of the wastewater tank, a sieve plate is fixedly connected to the inner wall of the wastewater tank to divide it into cavities, an extension plate is fixedly connected to both ends of the wastewater tank, and an L-shaped groove is opened at the top of the extension plate. Limiting studs are fixedly connected to the bottom of both sides of the dust collector main unit, and the L-shaped groove is engaged with the limiting studs.
[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: The dust collector main unit serves as the core load-bearing frame, connecting to external pipelines through interfaces at both ends. Two sets of internal mounting rails provide a stable mounting base for the filter plates, which are then engaged within these rails to form a layered filtration unit. A water tank at the top sprays liquid through nozzles, working in conjunction with the filter plates to form wet filtration. A wastewater tank at the bottom collects filtered wastewater directly opposite the nozzles. Four corner support columns ensure the stability of the main unit. The retaining strips at the top of the filter plates mate with the through-slots at the top of the main unit, providing a lateral positioning reference. Pressure strips within the mounting rails slide and adjust their position via guide rods, tightly abutting the edges of the filter plates. Combined with the elastic pressure of springs on the guide rod surfaces, this restricts lateral movement of the filter plates while accommodating minor deformations or assembly errors, maintaining a stable and secure fit. A pulse valve pipe at the top of one side of the dust collector main unit connects to a blower head via a pipeline, periodically releasing high-pressure gas to backflush and clean the filter plates, preventing clogging. A discharge trough at the bottom, corresponding to the bottom of the filter plates, discharges the filtered products. Mounting rails on both sides slide and engage with the receiving channels, facilitating the cleaning of accumulated impurities. The louvers on the inner wall, located on both sides of the spray head, guide the liquid to disperse evenly and slow down the airflow, enhancing the wet filtration effect. A drain head at one end of the wastewater tank facilitates wastewater discharge. The inner wall sieve plate separates impurities from the liquid, preventing clogging. The L-shaped groove at the top of the extension plate engages with the limiting studs on both sides of the main unit, allowing for detachable fixing and quick cleaning and maintenance of the wastewater tank. The overall structure, through modular design and functional synergy, balances filtration efficiency, operational stability, and ease of maintenance.

Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] Please see Figure 1-4 As shown, this embodiment provides an industrial dust collector with a multi-layer filtration structure, including: a dust collector main unit 100, mounting rails 200, filter plates 300, a water storage tank 600, and a wastewater tank 700. Both ends of the dust collector main unit 100 are fixedly connected to interfaces 106. Two sets of mounting rails 200 are provided, and the two sets of mounting rails 200 are respectively fixedly connected to both sides of the inner wall of the dust collector main unit 100. The filter plates 300 are snapped into the interior of the mounting rails 200. Two sets of equipment are provided. A water storage tank 600 is fixedly connected to the top of the dust collector main unit 100. A spray head 601 is fixedly connected to the top wall of the dust collector main unit 100. The spray head 601 is connected to the water storage tank 600. A wastewater tank 700 is located at the bottom of the dust collector main unit 100. The wastewater tank 700 is located directly below the spray head 601. The wastewater tank 700 is connected to the inner cavity of the dust collector main unit 100. Support columns 101 are fixedly connected to the four corners of the bottom of the dust collector main unit 100.
[0021] The connection to external pipelines is achieved through the two-end interfaces 106; two sets of mounting rails 200 are symmetrically arranged on both sides of the inner wall of the main unit 100, providing a stable mounting base for the filter plates 300; the two sets of filter plates 300 are snapped into the mounting rails 200, forming a layered filtration unit; the water storage tank 600 at the top sprays liquid downwards through the spray head 601, which works with the filter plates 300 to form wet filtration; the wastewater tank 700 at the bottom is directly opposite the spray head 601 and is used to collect the wastewater generated by filtration; the support columns 101 at the four corners provide stable support for the main unit 100. The overall structure operates collaboratively through modular design, achieving efficient filtration and centralized collection of wastewater, avoiding secondary pollution.
[0022] To simplify the installation process and reduce the risk of misalignment, its specific structure is as follows: Figure 1-3 As shown, a retaining strip 301 is fixedly connected to the top of the filter plate 300. A through groove is provided at the top of the dust collector main unit 100, matching the model and specifications of the retaining strip 301. The fit between the retaining strip 301 at the top of the filter plate 300 and the through groove at the top of the dust collector main unit 100 provides a lateral positioning reference for the installation of the filter plate 300, simplifying the installation process, reducing the risk of misalignment, and facilitating quick disassembly, maintenance, or replacement of the filter plate 300 later.
[0023] To improve installation compatibility, its specific structure is as follows: Figure 1-3 As shown, a pressure strip 201 is provided inside the mounting rail 200. A guide rod 202 is fixedly connected to one side surface of the pressure strip 201. The guide rod 202 is slidably inserted into the side wall of the mounting rail 200, and the other side surface of the pressure strip 201 is tightly abutted against the edge of the filter plate 300. By tightly abutting the edge of the filter plate 300 with one side surface of the pressure strip 201 inside the mounting rail 200, the lateral movement of the filter plate 300 within the mounting rail 200 can be restricted. The sliding insertion design of the guide rod 202 into the side wall of the mounting rail 200 allows the pressure strip 201 to be flexibly adjusted in the horizontal direction to adapt to filter plates 300 of different thicknesses or assembly errors, thus improving installation adaptability.
[0024] To prevent the filter plate 300 from loosening, its specific structure is as follows: Figure 1-3 As shown, a spring 203 is movably sleeved on the surface of the guide rod 202. One end of the spring 203 is in close contact with the surface of the pressure strip 201, and the other end of the spring 203 is in close contact with the inner wall of the mounting vertical rail 200. Through the spring 203 sleeved on the surface of the guide rod 202, one end of the spring 203 presses against the pressure strip 201, and the other end presses against the inner wall of the mounting vertical rail 200. The elastic restoring force of the spring 203 continuously pushes the pressure strip 201 to press the filter plate 300. Even if the filter plate 300 undergoes slight deformation due to long-term use, it can still maintain a tight fit, avoiding a decrease in filtration efficiency caused by the filter plate 300 loosening.
[0025] To prevent clogging of the filter channels, its specific structure is as follows: Figure 1-3 As shown, a pulse valve pipe 400 is fixedly connected to the top of one side surface of the dust collector main unit 100. Two blow nozzles 401 are fixedly connected to the pulse valve pipe 400 via pipes. The blow nozzles 401 are positioned on one side of the top of the filter plate 300. The two blow nozzles 401 are connected to the pulse valve pipe 400 at the top of one side of the dust collector main unit 100 via pipes, with the blow nozzles 401 facing the top of the filter plate 300. This allows for the periodic release of high-pressure gas to back-blow and clean the surface of the filter plate 300, effectively removing dust or particulate matter adhering to the filter plate 300, preventing clogging of the filter channels, and ensuring the continuous filtration performance of the filter plate 300.
[0026] To prevent impurities from accumulating and affecting equipment operation, its specific structure is as follows: Figure 1-3 As shown, the dust collector main unit 100 has two discharge troughs 103 at its bottom, corresponding to the bottom of the filter plate 300. Each discharge trough 103 has a fixed connection to both sides, and mounting rails 104 are fixedly connected to both sides of the discharge trough 103. A receiving channel 105 is located directly below the discharge trough 103, and the receiving channel 105 is slidably engaged with the mounting rails 104. Through the discharge troughs 103 at the bottom of the dust collector main unit 100 corresponding to the bottom of the filter plate 300, filtered dust or liquid can be collected and discharged. The sliding engagement of the mounting rails 104 on both sides of the discharge trough 103 with the receiving channel 105 provides stable positioning for the receiving channel 105 and facilitates periodic removal and cleaning of accumulated dust or liquid, preventing impurities from affecting equipment operation.
[0027] To prevent water from directly impacting the filter plate 300, its specific structure is as follows: Figure 1-2 As shown, two louvered grilles 500 are fixedly connected to the inner wall of the dust collector main unit 100, and the two louvered grilles 500 are arranged on both sides of the spray head 601. The two louvered grilles 500, which are fixedly connected to the inner wall of the dust collector main unit 100 and located on both sides of the spray head 601, can guide the liquid sprayed from the spray head 601 to be evenly dispersed, avoiding the water flow from directly impacting the filter plate 300 and causing excessive local pressure; at the same time, the louvered grilles 500 can slow down the airflow velocity, prolong the contact time between dust and liquid, and enhance the dust capture effect of wet filtration.
[0028] To ensure stable installation, its specific structure is as follows: Figure 1-4As shown. A drain head 701 is fixedly connected to one end of the wastewater tank 700. A sieve plate 703 is fixedly connected to the inner wall of the wastewater tank 700, dividing it into cavities. Extension plates are fixedly connected to both ends of the wastewater tank 700, and L-shaped grooves 702 are formed at the top of the extension plates. Limiting studs 102 are fixedly connected to the bottom of both sides of the dust collector main unit 100, and the L-shaped grooves 702 engage with the limiting studs 102. The drain head 701 at one end of the wastewater tank 700 facilitates centralized discharge of the internally collected wastewater; the cavitation design of the sieve plate 703 on the inner wall can separate larger particulate impurities from the liquid in the wastewater, preventing impurities from clogging the subsequent discharge pipes; the L-shaped grooves 702 at the top of the extension plates engage with the limiting studs 102 on both sides of the dust collector main unit 100, achieving both detachable fixing of the wastewater tank 700 to ensure stable installation and convenient removal of the wastewater tank 700 for cleaning and maintenance by disassembling the limiting studs 102.
