TECHNICAL FIELD

[0001] The utility model relates to a workshop fresh air technology field especially air filter device of workshop fresh air system. BACKGROUND

[0002] The fresh air system of the foam workshop is a complex air conditioning system, and its main function is to provide a constant temperature, humidity and pressure air environment for the spinning workshop. The system inhales external fresh air, adjusts the temperature and humidity through the composite foam air conditioner, and then sends the air into the foam workshop. At the same time, the process air after use is sucked into the process air fan through the return air pipe, mixed with fresh air, and then sent to the workshop again to form a cycle. Through fine adjustment and control, an ideal production environment is provided for the foam workshop.

[0003] After the air enters from the fresh air inlet, dust, lint and fibers and other impurities may be present. These impurities are easy to block the multi-stage filter bag, causing the filtering effect to continuously decrease. The common method is to maintain the filtering system, and remove dust and impurities through the spraying system (for reference, the background technology of application number CN202022429423.9, a suction device for a fresh air system). However, this method has the problems of high maintenance frequency and low cleaning efficiency, which affects the normal use of the fresh air system. UTILITARIAN CONTENT

[0014] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0015] Embodiment 1:

[0016] As shown in Figure 1 , Figure 2 The utility model discloses an air filtering device of workshop fresh air system, including connecting pipe 1, shell 3 and filter cylinder 2, the connecting pipe 1 is used for connecting the air inlet of fresh air system, the end of connecting pipe 1 is inserted into the inside of shell 3, and the shell 3 is sealingly connected with the connecting pipe 1, an air inlet is arranged on the side wall of shell 3 opposite to the connecting pipe 1, the filter cylinder 2 is sleeved on the connecting pipe 1 inside the shell 3, and the filter cylinder 2 is used for filtering air, a plurality of vertical wave-shaped plates 4 are arranged at intervals in the inside of shell 3 at the air inlet, a passage for air passing through is formed between the wave-shaped plates 4, a water inlet pipe 301 is arranged on the top of shell 3 directly above the wave-shaped plate 4, and a water outlet pipe 302 is arranged on the bottom of shell 3.

[0017] The corrugated plate 4 is arranged at the air inlet of the shell 3. During the process that the external air enters the interior of the shell 3 from the air inlet of the shell 3 and passes through the filter cylinder 2 to enter the connecting pipe 1, the external air needs to enter the interior of the shell 3 from the gap between the corrugated plates 4 first. The gap between the corrugated plates 4 is in a wavy structure, and the air entering process will generate turbulence. At the same time, the water inlet pipe 301 at the top of the shell 3 transports water inward, and the water is then split and flows downward along the corrugated plates 4, and finally is discharged from the water outlet pipe 302. During this process, due to the air turbulence, the impurities in the air will increase the contact with the water on the corrugated plate 4, so as to be adsorbed and discharged from the water outlet pipe 302 along the water flow. Of course, part of the impurities in the air will be filtered by the filter cylinder 2, so as to finally ensure that the air entering the connecting pipe 1 is clean and basically free of impurities, so as to improve the normal use performance of the fresh air system.

[0018] A sponge body 6 is arranged below the water inlet pipe 301 in the interior of the shell 3, and the sponge body 6 is located above the corrugated plate 4. The sponge body 6 covers the pipe opening of the water inlet pipe 301 and extends to the upper end of all the corrugated plates. The sponge body 6 is arranged below the water inlet pipe 301. After the water enters the sponge body 6, the water will not be directly concentrated and left, but diffused into the entire sponge body 6 and left from each part, so as to more comprehensively cover the corrugated plate, so that the water flows downward on the corrugated plate, so as to improve the cleaning of the impurities in the air passing between the corrugated plates.

[0019] The filter cylinder 2 and the connecting pipe 1 are rotationally connected through the bearing 201. The motor 202 is arranged on the connecting pipe 1 outside the shell 3. The output shaft of the motor 202 extends to the interior of the shell 3. The belt pulley is arranged on the output shaft of the motor 202 in the interior of the shell 3. The belt pulley is also arranged on the filter cylinder 2. The two belt pulleys are drivingly connected through the belt 203. The cutting head 5 is arranged on the end face of the filter cylinder 2 in intervals.

[0020] One end of the filter cylinder 2 is closed and is arrayed with filter holes, and the other end is sleeved with the end of the connecting pipe 1. The bearing 201 is arranged at the sleeving position of the two. The filter cylinder 2 and the connecting pipe 1 form a connecting pair through the bearing 201. The bearing 201 can adopt the existing commercially available sealed bearing 201. The output shaft of the motor 202 drives the filter cylinder 2 to rotate through the belt pulley and the belt 203. During the normal filtering process, the impurities such as fibers and lint will gather at the end of the filter cylinder 2, which will affect the filtering effect. During the rotation of the filter cylinder 2, due to the centrifugal force, the gathered impurities will be thrown outward and separated under the action of the cutting head 5 on the end face of the filter cylinder 2, so as not to be connected in a block shape, so as to be more easily separated and discharged from the water outlet pipe 302.

[0021] The cutting heads 5 are evenly spaced circumferentially on the end surface of the filter cartridge 2. The cutting heads 5 are stainless steel blades, which are not easily corroded during operation and have good performance. Moreover, the cutting heads 5 are evenly spaced, making it easier to cut impurities and achieving better results.

[0022] A first annular baffle 7 is provided at the air inlet of the housing 3, and the outer edge of the first annular baffle 7 is connected to the air inlet edge of the housing 3. The provision of the first annular baffle 7 can prevent water on the corrugated plate from flowing out of the air inlet of the housing 3, playing a role of water blocking.

[0023] A second annular baffle 8 is provided between the corrugated plate 4 and the air filter cartridge 2 inside the housing 3 , and an outer edge of the second annular baffle 8 is connected to the inner wall of the housing 3 .

[0024] The provision of the second annular baffle 8 can effectively prevent impurities cut off from the air filter cartridge 2 from entering between the corrugated plates 4 and causing blockage of the corrugated plates 4 .

[0025] The working principle of the utility model is as follows: the connecting pipe 1 is connected to the air inlet of the fresh air system and the water inlet pipe 301 is connected to the water supply pipeline, and the motor 202 is started. Under the action of negative pressure, air can enter from the air inlet of the shell 3 and be filtered by the air filter cartridge 2 to remove impurities in the air, and finally enter the fresh air system from the connecting pipe 1;

[0026] When the air passes through the gaps between the corrugated plates 4, the turbulence of the air between the corrugated plates 4 increases due to the curved shape of the corrugated plates 4. This helps the water flow on the corrugated plates 4 capture impurities contained in the air to complete the initial filtration. The impurities captured by the water flow can then be discharged from the water outlet pipe 302 together with the water flow, and the air will enter the rear end of the shell 3 under the action of negative pressure.

[0027] Subsequently, the remaining impurities contained in the air that has completed the initial filtration will be blocked by the air filter cartridge 2, and the air filter cartridge 2 will rotate rapidly under the drive of the motor 202. At this time, the impurities attached to the surface of the air filter cartridge 2 will be thrown off the surface of the air filter cartridge 2 under the action of centrifugal force and separated from the air filter cartridge 2, which helps to extend the working life of the filter medium and avoid impurities clogging the filter medium, causing the air filter cartridge 2 to fail quickly and require frequent cleaning. The impurities thrown off the air filter cartridge 2 can be uniformly discharged from the water outlet pipe 302.
