Description

Technical Field

[0001] The utility model belongs to the technical field of air purification, and specifically relates to an air filter. Background Art

[0002] Air filter refers to an air filtering device, which is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery and communication equipment. There are primary filter, medium filter, high efficiency filter and sub-high efficiency filter. Various models have different standards and performance. The main components of the air filter are the filter element and the casing. The filter element is the main filtering part, which is responsible for filtering the gas, and the casing is the external structure that provides necessary protection for the filter element. In order to provide more efficient air purification efficiency, multiple layers of air filters are often used to improve the filtering efficiency.

[0003] The main requirements of air filters are high filtration efficiency, good filtration effect, and long-term continuous use without maintenance. At present, existing air filters are all installed with fixed partitions. The smaller the partition spacing, the greater the air circulation resistance, the cleaner the air filtration, but the filtration efficiency is low; the larger the partition spacing, the smaller the air circulation resistance, the more dust content of the filtered air, but the filtration speed is faster. However, the dust content of air in different environments is different. If the partitions are all fixed, the air cannot be filtered well while minimizing the air circulation resistance, resulting in low filtration efficiency and poor filtration effect of the air filter. In addition, the filters currently used in the market are often placed in the external environment. Due to the harsh environment outside, heavy rain will invade the filter, and a large amount of rainwater will accumulate in the filter, causing the filter shell to be eroded by rainwater, broken and rotten, which in turn leads to the problem of shortened service life of various components inside the filter, shortening the overall filter service life and reducing the service life.

[0005] To achieve the above-mentioned purpose, the utility model provides an air filter, including a dust box body, which is composed of a plurality of mounting frames; a screen and a filter cloth are respectively provided on the front and rear sides of the dust box body, and a plurality of partitions are provided between the screen and the filter cloth; a protective box is provided on the top of the dust box body.

[0006] Preferably, the left and right sides of the dust box body and the bottom mounting frame are provided with a first drainage groove, the first drainage groove of the bottom mounting frame is provided with a plurality of drainage holes, and the drainage holes are provided with filters; a second drainage groove is provided on one side of the partition.

[0007] Preferably, a sliding hole is provided on the top of the dust box body, a plurality of sliding blocks are provided in the sliding hole, and a first mounting plate and a second mounting plate are respectively provided at both ends of the sliding block.

[0008] Preferably, a motor is provided at the bottom of each of the first mounting plates, and the output ends of the motor are connected to the top of the partition; and the rear sides of the two adjacent second mounting plates are respectively connected to the output ends of the same parallel cylinder.

[0024] Example

[0025] like Figure 1-3 As shown, an air filter comprises a dust box body 1, which is composed of a plurality of mounting frames 2. A screen 3 and a filter cloth are respectively arranged on the front and rear sides of the dust box body 1, and a plurality of partitions 4 are arranged between the screen 3 and the filter cloth. Particles and dust in the air are initially filtered through the screen 3 and then filtered twice through the filter cloth, thereby finally achieving the effect of purifying the air.

[0026] The left and right sides of the dust box body 1 and the bottom mounting frame 2 are both provided with first drainage grooves 6, and the first drainage grooves 6 of the bottom mounting frame 2 are provided with a plurality of drainage holes 7, and the drainage holes 7 are each provided with a filter 8, which can prevent debris outside the dust box body 1 from entering the interior. Figure 4As shown, a second drainage groove 9 is provided on one side of the partition 4. When a large amount of rainwater accumulates in the filter, the rainwater is drained through the first drainage groove 6 and the second drainage groove 9, and discharged out of the dust box body 1 through the drainage hole 7, which can avoid irreversible damage to various components of the equipment caused by the accumulation of rainwater and extend the life of the equipment.

[0027] like Figure 5-8 As shown, a sliding hole 10 is provided on the top of the dust box body 1, and a plurality of sliders 11 are provided in the sliding hole 10, and a first mounting plate 12 and a second mounting plate 13 are provided at both ends of the sliders 11. A motor 14 is provided at the bottom of the first mounting plate 12, and the output end of the motor 14 is connected to the top of the partition 4. The rear sides of two adjacent second mounting plates 13 are respectively connected to the output end of the same parallel cylinder 15. When it is necessary to adjust the spacing of the partition 4 according to the content of particles and dust in the air, the partition 4 can be rotated and moved left and right by starting the motor 14 and the parallel cylinder 15, so that the air can be better filtered while minimizing the air circulation resistance, thereby improving the filtering efficiency and filtering effect of the air filter.

[0028] A protective box 5 is provided on the top of the dust box body 1. A movable cover 16 is provided on the top of the protective box 5. The movable cover 16 is rotatably connected to the protective box 5 through a rotating assembly 17. A handle 18 is provided on the top of the movable cover 16 away from the rotating assembly 17. The protective box 5 can prevent rainwater from entering the interior of the dust box body 1 and damaging its internal components. When it is necessary to inspect or replace components, the movable cover 16 can be opened for easy inspection or replacement.

[0029] Therefore, the utility model adopts the above-mentioned air filter to solve the problem that the spacing between the existing air filter partitions cannot be adjusted, resulting in low filtration efficiency and poor filtration effect of the air filter, and can effectively prevent the accumulation of rainwater from causing irreversible damage to various components of the equipment.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
