Description

Technical Field

[0001] This utility model relates to the field of waste gas filtration technology, and in particular to a waste gas filtration device. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life activities, especially waste gas emitted from industrial sites such as chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries, as well as vehicle exhaust. These waste gases are one of the main sources of air pollution and have significant negative impacts on the environment and human health.

[0003] Exhaust gas often contains a large amount of dust and fine particles that are harmful to the human body. Traditional filtration devices will have their filters clogged by dust and fine particles after filtering the exhaust gas for a period of time, thus affecting the subsequent filtration of exhaust gas. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste gas filtration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste gas filtration device includes a filter housing, with an inlet pipe and an outlet pipe respectively provided at both ends of the filter housing, a discharge port provided at the bottom of the filter housing, three filter frames vertically slidably inserted inside the filter housing, the top of the filter frames being fixedly embedded in the top of the filter housing by screws, filter screens being provided inside the filter frames, and a base plate being horizontally inserted inside the filter housing.

[0007] The filter housing has a square groove on its back side, and a pull rod is slidably arranged in the square groove. Three impact components are installed on one side of the pull rod through three connectors.

[0008] In addition, a preferred structure is that the top of the filter housing has three sets of slots.

[0009] In addition, a preferred structure is that rubber strips are provided on both the top and bottom sides of the filter frame, and the rubber strips are engaged in the slots.

[0010] In addition, a preferred structure is that three sliding grooves are provided on one side of the inner wall of the filter housing, and the sliding grooves are connected to the square groove, and three baffles are fixedly installed on one side of the inner wall of the filter housing.

[0011] Furthermore, in a preferred configuration, the impact assembly includes a T-shaped rod that slides through a baffle, with an impact head at one end of the T-shaped rod, and the impact head making close contact with one side of the filter frame.

[0012] In addition, a preferred structure is that the T-shaped rod is fitted with a spring, and the two ends of the spring are fixedly installed to one side of the impact head and the other side of the baffle, respectively.

[0013] In addition, a preferred structure is that two sets of iron blocks are embedded and installed on one side of the filter housing.

[0014] In addition, a preferred structure is that magnet blocks are fixedly installed at both ends on one side of the base plate, and the magnet blocks are attracted to the iron blocks.

[0015] The beneficial effects of this utility model are as follows:

[0028] 1. 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.

[0029] Reference Figure 1-10 A waste gas filtration device includes a filter housing 1, with an inlet pipe 101 and an outlet pipe 102 respectively provided at both ends of the filter housing 1, a discharge port 103 provided at the bottom of the filter housing 1, three filter frames 3 vertically slidingly inserted inside the filter housing 1, the top of the filter frames 3 being fixedly embedded in the top of the filter housing 1 by screws, a filter screen 31 being provided inside the filter frames 3, and a base plate 2 being horizontally inserted inside the filter housing 1.

[0030] The filter housing 1 has a square groove 104 on its back side, and a pull rod 5 is slidably arranged in the square groove 104. Three impact components 6 are installed on one side of the pull rod 5 through three connectors 9.

[0031] Meanwhile, the top of the filter housing 1 has three sets of slots 106.

[0032] Furthermore, rubber strips 32 are provided on both the top and bottom sides of the filter frame 3. The rubber strips 32 are inserted into the slots 106 to enhance the sealing and prevent exhaust gas from escaping.

[0033] Meanwhile, three sliding grooves 105 are provided on one side of the inner wall of the filter housing 1, and the sliding grooves 105 are connected to the square groove 104. Three baffles 7 are fixedly installed on one side of the inner wall of the filter housing 1.

[0034] Meanwhile, the impact component 6 includes a T-shaped rod 62, which slides through the baffle 7. One end of the T-shaped rod 62 is provided with an impact head 61, which is in close contact with one side of the filter frame 3, so that the impact head 61 can impact the filter frame 3, causing the filter frame 3 and the filter screen 31 to vibrate.

[0035] Furthermore, a spring 63 is fitted around the T-shaped rod 62. The two ends of the spring 63 are fixedly installed on one side of the impact head 61 and the other side of the baffle 7, respectively. The impact head 6 impacts the filter frame 3 under the elastic action of the spring 53.

[0036] Meanwhile, two sets of iron blocks 8 are embedded and installed on one side of the filter housing 1.

[0037] Furthermore, magnet blocks 4 are fixedly installed at both ends on one side of the base plate 2. The magnet blocks 4 attract the iron block 8 and limit the position of the base plate 2.

[0038] In this embodiment, the air inlet pipe 101 and air outlet pipe 102 of the filter device are respectively connected to external pipes. When the exhaust gas enters the filter housing 1 through the air inlet pipe 101, the dust and other particulate matter in the exhaust gas are intercepted and trapped in the filter screen 31 under the filtering action of the filter screen 31, and the clean air is discharged through the air outlet pipe 102 after passing through the filter screen 31. After this filtration is completed, the bottom plate 2 is pulled horizontally to separate the magnet block 4 from the iron block 8, and the bottom plate 2 is taken out from the filter housing 1. Then the discharge port 103 is opened. At this time, the pulling rod 5 is pulled, and the pulling rod 5 passes through three Each connector 9 drives the three impact heads 61 to move synchronously. The T-shaped rod 62 slides inside the baffle 7, and the spring 63 is squeezed between the impact head 61 and the baffle 7. Then the pull rod 5 is loosened. At this time, the impact head 61 hits one side of the filter frame 3 under the elastic action of the spring 63, causing the filter frame 3 and the filter screen 31 to vibrate. At this time, the dust and other particles trapped in the filter screen 31 are released from the filter screen 31 under the action of vibration and then discharged through the discharge port 103. Repeat the above operation multiple times so that most of the dust is released from the filter screen 31.

[0039] When the filter screen 31 is used for a long time, a large amount of particles that are difficult to be removed by vibration will accumulate. At this time, turn the screws, take out the filter frame 3, clean the filter screen 31, and then insert the filter frame 3 vertically into the filter housing 1 and tighten it with screws.

[0040] In this invention, by pulling and releasing the pulling rod 5, the impact component 6 is driven to impact the filter frame 3, causing the filter frame 3 to vibrate. Dust and fine particles are dislodged from the filter screen 31 under the action of vibration, effectively preventing the filter screen 31 from becoming clogged, which is beneficial for long-term filtration of exhaust gas.

[0041] 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.
