Description

Technical Field

[0001] This utility model relates to a filtration device, and more particularly to a vacuum pump filtration device. Background Technology

[0002] The negative pressure operation at the kiln tail of a rotary kiln is a key aspect of its efficient operation. By using the exhaust fan at the kiln tail, a low-pressure airflow environment, known as kiln tail negative pressure, is created. This design ensures that flue gas can be smoothly discharged from the kiln head, maintaining high-speed flow and negative pressure of the flue gas, effectively guaranteeing normal emission of flue gas. At the same time, the negative pressure can introduce fresh hot airflow into the kiln, which greatly accelerates the calcination process of raw materials, improves production efficiency, and significantly reduces energy consumption in the cement production process through the recycling of hot airflow. It also helps control waste gas emissions, reduces environmental pollution, and embodies the concept of environmental protection.

[0003] In summary, the negative pressure operation at the kiln tail of the rotary kiln not only optimizes the production process but also achieves multiple goals of high efficiency, energy saving, and environmental protection. In order to maintain negative pressure at the kiln tail, a vacuum pump is needed to extract the air inside. Since the rotary kiln generates a large amount of dust during the production process, the incoming air needs to be filtered to prevent dust from entering the vacuum pump and damaging it. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vacuum pump filter device to prevent dust in the air from entering the vacuum pump.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum pump filtration device, comprising a body assembly, the body assembly including a pump body and a ventilation pipe disposed on one side of the pump body and communicating with the air inlet of the pump body so that air enters the pump body through the ventilation pipe, a filter assembly disposed inside the ventilation pipe, one end of the filter assembly being provided with a shielding component via a fixing component; the fixing component including a fixing plate, the side wall of the fixing plate being fixedly connected to the inner wall of the ventilation pipe, the fixing plate having a first ventilation groove; the shielding component including a filter plate, the filter plate being rotatably connected to the fixing plate, the filter plate having a second ventilation groove, the side wall of the filter plate being fixedly connected to a lever, the lever being slidably connected to the interior of a groove formed on the ventilation pipe.

[0006] Furthermore, a connecting component is provided at one end of the body component.

[0007] Furthermore, the connecting assembly includes a connecting frame, one end of which is fixedly engaged with one end of the ventilation pipe. A threaded rod is threadedly connected inside the connecting frame, and a movable rod is slidably connected inside the connecting frame. One end of the movable rod is in contact with one end of the threaded rod.

[0008] Furthermore, a ventilation component is provided at one end of the connecting component.

[0009] Furthermore, the ventilation assembly includes a movable plate and a connecting plate. The side of the movable plate is fixedly connected to the other end of the movable rod, and the side wall of the movable plate is slidably connected to the inner wall of the ventilation duct. A first slot is formed inside the movable plate. The side wall of the connecting plate is fixedly connected to the inner wall of the ventilation duct, and a second slot is formed inside the connecting plate.

[0010] Furthermore, the filter assembly includes a filter element, the side of which is fixedly installed inside the ventilation duct, and a baffle is fixedly installed at one end of the filter element.

[0011] Furthermore, the first slot and the second slot are staggered, and the first ventilation slot and the second ventilation slot are correspondingly arranged.

[0012] This utility model provides a vacuum pump filtration device, which has the following beneficial effects:

[0013] This vacuum pump filtration device discharges filtered air through a first ventilation slot in conjunction with a corresponding second ventilation slot. When the filter element needs to be replaced after prolonged use, rotating the lever moves it inside the slide groove, causing the lever to rotate the filter plate. This misaligns the first and second ventilation slots, allowing the filter plate to filter the air mixed with dust. This prevents dust-laden air from entering the pump body when the filter element is replaced, thus avoiding dust damage to the pump body and improving the effectiveness of preventing dust from entering the pump body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] The vacuum pump filtration device provided in this embodiment improves the filter structure to provide the advantage of filter element resistance during replacement. Specifically, taking a filtration device as an example, as a preferred solution in this embodiment, the filtration device is specifically a vacuum pump filtration device, which can prevent dust from entering during filter element replacement in vacuum pump filtration.

[0021] like Figure 1 and Figure 2 The vacuum pump filtration device shown includes a body assembly 1, a connecting assembly 2 at one end of the body assembly 1, a ventilation assembly 3 at the other end of the connecting assembly 2, a filter assembly 4 and a fixing assembly 5 inside the body assembly 1, and a shielding assembly 6 on the side of the fixing assembly 5. The body assembly 1 includes a pump body 101, and a ventilation pipe 102 is fixedly installed on the side of the pump body 101. A sliding groove 103 is opened on the side wall of the ventilation pipe 102. When the pump body 101 is started, the air inside the rotary kiln is extracted, and the gas is guided through the ventilation pipe 102.

[0022] In this embodiment, as Figure 2 As shown, the connecting assembly 2 includes a connecting frame 201. One end of the connecting frame 201 is fixedly engaged with one end of the ventilation pipe 102. A threaded rod 202 is threadedly connected inside the connecting frame 201. A movable rod 203 is slidably connected inside the connecting frame 201. One end of the movable rod 203 is in contact with one end of the threaded rod 202. The connecting frame 201 is fixed to one end of the ventilation pipe 102. At this time, rotating the threaded rod 202 will push the movable rod 203 to move inside the connecting frame 201, so that the movable rod 203 can slide inside the connecting frame 201.

[0023] like Figure 3As shown, the ventilation assembly 3 in this embodiment includes a movable plate 301 and a connecting plate 303. The movable plate 301 is fixedly connected to the movable rod 203. The side wall of the movable plate 301 is slidably connected to the inner wall of the ventilation pipe 102. The movable plate 301 has a first slot 302. The side wall of the connecting plate 303 is fixedly connected to the inner wall of the ventilation pipe 102. The connecting plate 303 has a second slot 304. The movable plate 301 is pushed to slide inside the ventilation pipe 102 by the movable rod 203, thereby controlling the distance between the movable plate 301 and the connecting plate 303. Since the first slot 302 and the second slot 304 are misaligned, the air intake volume inside the ventilation pipe 102 is controlled. The filter assembly 4 includes a filter element 401, which is fixedly installed inside the ventilation duct 102. A baffle 402 is fixedly installed at one end of the filter element 401. When air enters the ventilation duct 102, the filter element 401 filters the dust mixed in the air. The filter element 401 is assembled inside the ventilation duct, and the baffle 402 is fixedly installed in conjunction with the filter element 401 to ensure the filtration effect of the dust in the air.

[0024] In this embodiment, as Figure 4 As shown, the fixing component 5 includes a fixing plate 501. The side wall of the fixing plate 501 is fixedly connected to the inner wall of the ventilation pipe 102. A plurality of first ventilation slots 502 are provided on the fixing plate 501. The filtered air is ventilated through the first ventilation slots 502 on the fixing plate 501 inside the ventilation pipe 102.

[0025] See Figure 3 The shielding component 6 in this embodiment includes a filter plate 601, which is rotatably connected to a fixing plate 501. The filter plate 601 has several second ventilation slots 602 inside, with the number of first and second ventilation slots being equal. A lever 603 is fixedly connected to the side wall of the filter plate 601, and the lever 603 is slidably connected to a sliding groove 103. The filtered air is discharged through the first ventilation slot 502 in conjunction with the corresponding second ventilation slot 602. When the filter element 401 needs to be replaced after prolonged use, firstly, the connecting component 2 and ventilation component 3, which are fixedly installed at one end of the ventilation pipe 102, are disassembled, and then the matching component is removed from inside the ventilation pipe 102. When the filter element 401 is installed, the lever 603 is rotated to move it inside the slide groove 103. Since the opening width of the slide groove 103 is less than the thickness of the filter plate 601, the side end of the filter plate 601 that slides in contact with the ventilation duct 102 is sealed to the slide groove 103, preventing air from entering the duct 102 from the slide groove 103. When the lever 603 drives the filter plate 601 to rotate, the first ventilation groove 502 and the second ventilation groove 602 are misaligned, so that the filter plate 601 filters the air mixed with dust, thereby preventing the air mixed with dust from entering the pump body 101 when the filter element 401 is replaced, and thus preventing the dust from damaging the pump body 101.

[0026] When using the vacuum pump filtration device of this embodiment, firstly, the connecting frame 201 is fixed to one end of the ventilation pipe 102. The threaded rod 202 is rotated to push the moving rod 203 inside the connecting frame 201, causing the moving rod 203 to slide inside the connecting frame 201. The moving rod 203 pushes the moving plate 301 to slide inside the ventilation pipe 102, thereby controlling the distance between the moving plate 301 and the connecting plate 303. Due to the misalignment of the first slot 302 and the second slot 304, the air intake inside the ventilation pipe 102 is controlled. The pump body 101 is started to extract air from the rotary kiln. At this time, the gas is guided through the ventilation pipe 102. The air inside the kiln enters the ventilation pipe 102 and is filtered by the filter element 401 to remove dust mixed in the air. At this time, the baffle 402 cooperates with the filter element 401 to filter the air intake. The filter is fixed in place to ensure the filtration effect of dust in the air. The filtered air passes through the fixed plate 501 inside the ventilation pipe 102 and is ventilated through the first ventilation groove 502 inside the fixed plate 501. The first ventilation groove 502 cooperates with the corresponding second ventilation groove 602 to discharge the filtered air. When the filter element 401 needs to be replaced after long-term use, the lever 603 is rotated to move it inside the slide groove 103. This allows the lever 603 to drive the filter plate 601 to rotate, so that the first ventilation groove 502 and the second ventilation groove 602 are misaligned. This allows the filter plate 601 to filter the air mixed with dust, thereby preventing the air mixed with dust from entering the pump body 101 when the filter element 401 is replaced, and thus preventing dust from damaging the pump body 101.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
