Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a dust collector with a filter element self-cleaning function. Background Technology

[0002] In many scenarios such as industrial production, warehousing and logistics, and workshop processing, the air is often filled with large amounts of dust, particulate matter, and other impurities. These pollutants not only adversely affect the normal operation of production equipment, accelerating wear and aging and reducing its lifespan, but also pose a serious threat to the health of operators. Long-term exposure to high-dust environments can easily lead to respiratory diseases and other health problems. Therefore, effectively purifying airborne dust is a crucial step in ensuring production safety and the health of personnel.

[0003] Currently, there are many types of dust collectors on the market, among which cartridge dust collectors are widely used due to their high dust removal efficiency and relatively simple structure. However, traditional cartridge dust collectors still have many problems in actual use. On the one hand, when dealing with airflows containing a large amount of dust, the filtration load of a single filter element is large, which can easily lead to a decrease in filtration efficiency and rapid clogging. This makes it difficult to meet the rapid dust removal requirements in high-volume, high-concentration dust environments, affecting the overall purification effect and work efficiency.

[0004] On the other hand, after prolonged use, a large amount of dust and impurities accumulate on the surface of the filter element. If not cleaned in time, this will reduce the filter element's air permeability, increase the operating resistance of the equipment, and consume more energy. Most existing filter element cleaning methods require manual disassembly for cleaning or replacement, which is not only cumbersome and time-consuming, increasing labor costs, but also potentially causing secondary pollution during disassembly and installation. Frequent disassembly can also affect the sealing of the connection between the filter element and the equipment, reducing dust removal efficiency. Furthermore, the complex filter element installation structure of some dust collectors makes filter element replacement and maintenance difficult, causing considerable inconvenience to users.

[0005] Therefore, it is necessary to design a dust collector with a self-cleaning filter function to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dust collector with a self-cleaning filter element. This invention uses four dust collectors to quickly remove dust from the airflow, and facilitates the installation and disassembly of the filter element body. Furthermore, the horizontal pipe and transmission assembly allow the dust on the filter element body to be blown off and collected.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dust collector with a self-cleaning filter element includes a housing. An air inlet is located at the upper end of the housing. A horizontal plate is fixedly connected inside the housing, and a vertical plate is fixedly connected to the lower end of the horizontal plate. The horizontal and vertical plates divide the internal space of the housing into an air intake chamber, a filter chamber, and an installation chamber. An opening is located at the rear of the installation chamber. An air intake assembly is installed at the upper end of the horizontal plate, and the air outlet of the air intake assembly communicates with the filter chamber. Four filter elements are installed inside the filter chamber. Each filter element includes a first circular opening on the vertical plate. A second disc is rotatably connected to the first circular opening. Three horizontal bars are fixedly connected to the front of the second disc. A fixing frame is fixedly connected to the front of the three horizontal bars. A threaded rod is fixedly connected to the front of the fixing frame. A first disc is sleeved on the threaded rod. A filter element body is fixedly connected to the rear of the first disc. A nut is threaded onto the threaded rod. Multiple second circular openings are located on the front of the housing, and multiple first discs are located within these second circular openings.

[0009] Preferably, a rotating rod is fixedly connected to the rear side of each of the second discs. The rotating rod has a hollow structure, and one end of the rotating rod is connected to the internal space of the filter element body. Multiple rotating rods are connected by a transmission assembly. An installation plate is fixedly connected to the inner walls of the left and right sides of the mounting cavity. A drive motor is installed on the installation plate, and the end of the output shaft of the drive motor is fixedly connected to the rotating rod located below.

[0010] Preferably, an air pump is installed on the rear side of the vertical plate, and a horizontal pipe is fixedly connected to the front side of the vertical plate. The outer wall of the horizontal pipe is provided with multiple air outlets, and the air outlet end of the air pump is connected to the horizontal pipe through an air injection pipe.

[0011] Preferably, the bottom of the filter chamber is connected to a dust collection box, and multiple inclined plates are fixedly connected to the inner walls of the front and rear sides of the dust collection box.

[0012] Preferably, the transmission assembly includes sprockets mounted on multiple rotating rods, and the multiple sprockets are connected by a chain drive.

[0013] Preferably, a controller is mounted on the left side of the housing.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] 1. Compared with existing technologies, this device significantly improves the overall filtration area and processing capacity by setting four filtration components. It can quickly and efficiently remove dust from airflow in high-volume, high-concentration dust environments, effectively avoiding the problems of decreased filtration efficiency and clogging caused by excessive filtration load on a single filter element.

[0016] 2. Compared with the existing technology, this device uses a transmission component to drive the rotating rod and filter body to rotate, and at the same time, the air outlet of the horizontal pipe sprays out air, which can perform a comprehensive and uniform self-cleaning of the filter body without the need for manual disassembly and cleaning. This not only saves labor costs and reduces the complexity of operation, but also avoids secondary pollution that may be generated during disassembly, and ensures the stability of dust removal effect.

[0017] 3. Compared with existing technologies, the filter element body of the device is connected to the fixing frame and the second disc through threaded rods and nuts, making the installation and disassembly process simple and convenient. This solves the problem of difficult replacement and maintenance caused by the complex installation structure of some dust collector filter elements, and greatly reduces the maintenance cost and time cost of the equipment.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4A dust collector with a self-cleaning filter element includes a housing 1. An air inlet 2 is located at the upper end of the housing 1, and a protective grille can be installed at the air inlet 2 to prevent large debris from entering the equipment. A horizontal plate is fixedly connected inside the housing 1, and a vertical plate is fixedly connected to the lower end of the horizontal plate. The horizontal and vertical plates are perpendicular to each other and are both made of high-strength steel plates to ensure stable separation of the internal space of the housing 1. The horizontal and vertical plates divide the internal space of the housing 1 into an air intake chamber, a filter chamber, and an installation chamber. The air intake chamber is located above the horizontal plate, the filter chamber is located below the horizontal plate and in front of the vertical plate, and the installation chamber is located behind the vertical plate. An opening is provided on the rear side of the installation chamber, and a removable cover can be installed at the opening for easy inspection and maintenance of the components inside the installation chamber. A suction assembly 12 is installed at the upper end of the horizontal plate. The suction assembly 12 can be a centrifugal fan or a high-pressure blower, providing stable suction power. The air outlet of the suction assembly 12 is connected to the filter chamber, which contains four filter components arranged symmetrically in two rows, significantly increasing the air handling capacity per unit time. Each filter component includes a first circular opening on a vertical plate, within which a second disc 17 is rotatably connected. A sealed bearing is installed between the second disc 17 and the first circular opening to ensure smooth rotation and prevent air leakage. Three horizontal bars 11 are fixedly connected to the front of the second disc 17, evenly distributed circumferentially to provide stable support for the mounting frame 10. The front of the three horizontal bars 11 is also fixedly connected to the mounting frame 10, which in turn is fixedly connected to a threaded rod 5. A first disc 4 is fitted onto the threaded rod 5, with its edge tightly fitted against the inner wall of the second circular opening to seal the filter chamber. A filter element body 9 is fixedly connected to the rear of the first disc 4. The filter element body 9 can be made of pleated filter cloth or HEPA filter material, providing high-efficiency dust filtration. A nut is threaded onto the threaded rod 5, and a washer can be installed between the nut and the first disc 4 to enhance the tightness of the fixation. The front side of the housing 1 is provided with multiple second circular openings, and multiple first discs 4 are located inside the second circular openings.

[0025] Each second disc 17 has a rotating rod 15 fixedly connected to its rear side. The rotating rod 15 has a hollow structure, and the hollow channel allows the filtered clean air to flow smoothly. One end of the rotating rod 15 communicates with the internal space of the filter element body 9. Multiple rotating rods 15 are connected by a transmission assembly 16. The transmission assembly 16 includes sprockets mounted on multiple rotating rods 15. The multiple sprockets are connected by a chain drive, which features smooth transmission and low power loss. The left and right inner walls of the mounting cavity are fixedly connected to a mounting plate 8. The mounting plate 8 is fixed to the inner wall of the housing 1 with bolts to ensure a stable installation. A drive motor 7 is mounted on the mounting plate 8. The drive motor 7 is a servo motor, and its speed can be adjusted by a controller 3. The output shaft of the drive motor 7 is fixedly connected to the rotating rod 15 located below. A controller 3 is mounted on the left side of the housing 1. The controller 3 can integrate a PLC control module to realize the automated control of the suction assembly 12, the drive motor 7, and the air pump 6.

[0026] An air pump 6 is installed on the rear side of the vertical plate, which generates high-pressure airflow to meet the air pressure requirements for cleaning the filter element. A horizontal pipe 14 is fixedly connected to the front side of the vertical plate. The horizontal pipe 14 is made of corrosion-resistant metal tubing to ensure structural stability under high-pressure airflow. The outer wall of the horizontal pipe 14 has multiple air outlets facing the surface of the filter element body 9 and is staggered to achieve comprehensive cleaning. The air outlet of the air pump 6 is connected to the horizontal pipe 14 through an air injection pipe 13. A dust collection box 18 is connected to the bottom of the filter chamber. The dust collection box 18 is connected to the filter chamber by a drawer-type connection, which facilitates periodic removal and cleaning of dust. Multiple inclined plates 19 are fixedly connected to the inner walls of the front and rear sides of the dust collection box 18. The inclined plates 19 are set at an angle downwards to guide dust to gather in the middle of the dust collection box 18 and prevent dust from accumulating in the corners.

[0027] The functional principle of this utility model can be explained through the following operation: First, during dust removal, the dust-laden airflow enters the suction chamber through the air inlet 2 at the upper end of the housing 1. At this time, the suction assembly 12 at the upper end of the horizontal plate is activated, drawing the dust-laden airflow in the suction chamber to the filter chamber. The four filter components in the filter chamber work simultaneously. When the dust-laden airflow passes through the filter element body 9, the dust and impurities are trapped by the filter element body 9, and the filtered clean airflow is discharged through the internal space of the filter element body 9 via the rotating rod 15, achieving efficient purification of the airflow.

[0028] When self-cleaning of the filter element body 9 is required, the drive motor 7 and air pump 6 are activated via the controller 3. The output shaft of the drive motor 7 drives the lower rotating rod 15 to rotate. Under the transmission action of the transmission assembly 16, the other rotating rods 15 rotate synchronously, thereby driving the second disc 17, the crossbar 11, the fixing frame 10, and the filter element body 9 to rotate together. At the same time, the air pump 6 delivers high-pressure gas to the horizontal tube 14 through the air injection pipe 13. The high-pressure gas is ejected from multiple air outlets on the outer wall of the horizontal tube 14, which blows the surface of the rotating filter element body 9 in all directions, blowing off the attached dust.

[0029] The blown dust falls to the bottom of the filter chamber under the action of gravity, and then enters the dust collection box 18. Multiple inclined plates 19 in the dust collection box 18 can guide the dust to gather, prevent the dust from flying, and facilitate subsequent centralized cleaning.

[0030] If the filter element body 9 needs to be replaced or maintained, simply unscrew the nut on the threaded rod 5 from the second round opening on the front side of the housing 1 to remove the first disc 4 and the filter element body 9 from the housing 1. During installation, place the filter element body 9 on the threaded rod 5 so that the first disc 4 is embedded in the second round opening, and then tighten the nut to complete the fixation. The operation is simple and convenient.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
