The third motor 23 controls the receiving shaft 22 to rotate, and the external end 24 drives the brush 25 to rotate, so that the brush 25 frictionally adapts to the rake tooth block 153, so as to achieve the effect of cleaning impurities on the surface of the component, thereby achieving the cleaning effect of the component, avoiding long-term adsorption of materials, affecting the subsequent grasping effect of the component, and avoiding impurities from corroding the component, thereby extending the service life of the equipment. The cleaning mechanism 26 frictionally adapts to the brush 25, so as to achieve the effect of cleaning impurities inside the brush 25, thereby achieving a certain self-cleaning effect, and preventing the subsequent friction effect of the brush 25 from being affected.
[0044] The cleaning mechanism 26 includes a cleaning frame 261, a first electric push rod 262 fixedly connected to the top of the cleaning frame 261, a connecting plate 263 fixedly connected to one side of the outside of the first electric push rod 262, a soft rubber column 265 fixedly connected to the side of the outside of the connecting plate 263 away from the first electric push rod 262, and an external bracket 264 fixedly connected to the outside of the soft rubber column 265. The first electric push rod 262 controls the distance between the soft rubber column 265 and the brush 25, thereby facilitating its contact with the inside of the brush 25. During the rotation of the brush 25, it rubs against the soft rubber column 265, thereby stripping impurities from the surface of the brush 25, preventing excessive accumulation of impurities inside the component and preventing them from affecting subsequent cleaning of the component. The external bracket 264 is arranged on the outside of the soft rubber column 265 to increase the contact area between the component, further improving the impurity stripping effect, and enhancing the cleaning effect of the component.
[0045] The third embodiment, based on the first and second embodiments, see Figures 8 to 10 As shown, the exhaust mechanism 28 includes an exhaust housing 281. A hole 282 is formed on the exterior of the exhaust housing 281 near the brush 25. A slide block 283 is fixedly connected to the inner wall of the exhaust housing 281 away from the hole 282. A friction mechanism 284 is slidably connected to the outer side of the slide block 283. Wind is generated by the fan 27 and blown through the exhaust housing 281 through the hole 282 toward the equipment, thereby flushing impurities from the surface of the components. The exhaust housing 281 acts as a barrier to impurities, preventing them from splashing when the brush 25 rotates and rubbing against impurities on the surface of the components, preventing them from entering the fan 27 and damaging the fan 27, thereby preventing them from affecting the subsequent operation of the components. The friction mechanism 284 slides on the slide block 283, causing the friction mechanism 284 to rub the side of the exhaust housing 281 near the hole 282, thereby cleaning impurities from the surface of the components and preventing impurities from clogging the hole 282 and affecting the ventilation of the components.
[0046] The friction mechanism 284 includes a friction frame body 2841, a second electric push rod 2842 is fixedly connected to an outer side of the friction frame body 2841, a receiving plate 2843 is fixedly connected to an outer side of the second electric push rod 2842 away from the friction frame body 2841, a friction shell 2844 is fixedly connected to an outer side of the receiving plate 2843 away from the second electric push rod 2842, a spherical block 2846 is provided on the inner side of the friction shell 2844, and a friction film 2845 is fixedly connected to an outer side of the friction shell 2844 close to the hole 282. The friction frame 2841 slides on the slide block 283 to achieve the purpose of reciprocating operation of the component. The distance between the friction shell 2844 and the side of the hole 282 is controlled by the second electric push rod 2842 to avoid excessive wear of the component due to long-term friction, thereby extending the service life of the component. When the friction film 2845 is in contact with one side of the hole 282, the spherical block 2846 squeezes each other on the friction shell 2844 to achieve the effect of shock absorption and buffering, avoiding damage to the component due to excessive extrusion pressure. Secondly, it is convenient for the component to fit on the surface of the component, so that the friction film 2845 rubs against the side of the hole 282, thereby realizing the cleaning operation of the component, avoiding blockage of the hole 282, and preventing the ventilation effect of the component from being affected.
[0047] 10. A method for adjusting the gap of a self-cleaning screen decontamination machine for sewage treatment, comprising the following steps:
[0048] Step 1: Cutting. The sewage flows from one side of the guide plate 16. Impurities in the sewage enter the cutting mechanism 17. The cutting mechanism 17 cuts the material in the sewage to reduce the volume of the material, avoid the large volume causing incompatibility with the equipment, and prevent the equipment from affecting operation.
[0049] Step 2: Grabbing. The first motor 14 controls the connecting shaft 12 to rotate, causing the chain belt 19 to drive the rake mechanism 15 to rotate, thereby achieving the function of driving the material to move, thereby achieving the cleaning operation of sewage impurities, intercepting and removing solid debris in the water, and preventing pipes and equipment from being blocked;
[0050] Step 3: Adjustment: The sliding block 152 slides on the rake tooth guide rail 151 to adjust the distance between the rake tooth blocks 153, thereby adjusting the rake tooth spacing to meet the subsequent operation requirements and avoid the material being stuck with the rake teeth, thereby avoiding affecting the subsequent operation efficiency;
[0051] Step 4: cleaning. When the rake tooth mechanism 15 rotates to grab the material, the composite device 2 performs friction cleaning on the rake tooth mechanism 15 to clean the impurities on the surface of the component, thereby achieving a cleaning effect on the component.
[0052] During use, sewage flows from one side of the cutting mechanism 17 to the dirt removal frame 11, and the cutting mechanism 17 cuts the material in the sewage to reduce the volume of the material, avoids the large volume causing incompatibility with the equipment, prevents the equipment from being affected, and prevents the material from being stuck in the equipment, prevents the operation efficiency from being affected, and the first motor 14 controls the connection shaft 12 to rotate, and the connection shaft 12 controls the rotating frame 13 to drive the chain belt 19 to rotate. During the rotation of the chain belt 19, the rake mechanism 15 is driven to rotate, and the rake mechanism 15 grabs the material, thereby achieving the effect of driving the material to move, thereby realizing the cleaning operation of sewage impurities, and the chain belt 19 rotates. Drive the sewage material to move and clean, and adjust the rake tooth density through the rake tooth mechanism 15 to achieve the function of adjusting the grabbing range, so as to meet the subsequent different operation requirements, and facilitate the subsequent cleaning of the rake teeth. A composite device 2 is set on one side of the decontamination frame 11, and the rake tooth mechanism 15 is cleaned through the composite device 2 to achieve the function of cleaning impurities on the surface of the equipment, avoid excessive accumulation of impurities, avoid "decreased grabbing ability", ensure that debris is effectively removed, prevent "equipment jamming or damage", avoid excessive operating resistance, reduce "secondary pollution", avoid backflow of debris or breeding of bacteria, so as to maintain the normal operation of the equipment and avoid affecting the equipment operation efficiency.
