Under the action of the collection frame 401, the sludge is centrally collected and processed. Subsequently, the user pulls the baffle door 104 to remove the baffle door 104 from the surface of the fixed box 101, and then pulls the collection frame 401 to pull the collection frame 401 out of the inside of the fixed box 101, and processes the sludge inside the collection frame 401 to realize the sludge processing function of the filter device.

[0032] Working principle: When in use, first place the device body 1 at the designated position, the user places the installation tube 107 on the surface of the water inlet pipe 106, and places the assembly tube 113 on the surface of the water outlet pipe 112, so that the installation tube 107 and the assembly tube 113 respectively drive the U-shaped frame 108 to move to contact the surfaces of the water outlet pipe 112 and the water inlet pipe 106, and the user tightens the installation studs 114 on the surface of the U-shaped frame 108, and under the action of the installation studs 114, the installation plate is driven to move to contact the surfaces of the water inlet pipe 106 and the water outlet pipe 112, and the installation tube 107 is installed on the surface of the water inlet pipe 106, and the assembly tube 113 is installed on the surface of the water outlet pipe 112. Subsequently, the hatching water enters the interior of the water guide pipe 109 through the installation tube 107 and the water inlet pipe 106, and the hatching water enters the interior of the filter box 105 through the pipe body 110.

[0033] Subsequently, the hatching water is filtered under the action of the filter grid plate 3032 inside the filter box 105, and then the hatching water enters the surface of the plate body 302, so that the hatching water enters the surface of the filter mesh plate 301 through the through-hole body 3031, and the hatching water is filtered again under the action of the filter mesh plate 301, so that the hatching water can obtain a better filtering and purification effect, so as to realize the function of the filter device to filter water in multiple layers, so that the filter device can perform multi-layer filtering and purification on the hatching water when in use, so that the filter device has a better filtering and purification effect on the hatching water.

[0034] Subsequently, the hatching water is purified under the action of the purification mesh 111. When the purification mesh 111 is used for a long time, the surface is prone to clogging. The user opens the door 102 and pulls the purification mesh 111 inside the filter box 105, so that the purification mesh 111 drives the fixed slider 2031 to slide inside the fixed slide groove 2032. Under the joint action of the fixed slider 2031 and the fixed slide groove 2032, the purification mesh 111 is guided. At this time, the elastic force of the spring body 202 inside the groove drives the arc-shaped clamping member 2033 to move. The arc-shaped clamping member 2033 moves away from one side of the purification mesh plate 111 toward the inside of the groove. At this time, the purification mesh plate 111 is away from the inside of the support frame 201, so that the purification mesh plate 111 is pulled out from the inside of the filter box 105, and the purification mesh plate 111 is replaced and cleaned to realize the anti-clogging function of the filter device. When the filter device is used, it can avoid the problem of surface clogging of the purification mesh plate 111 causing a reduction in water intake, which in turn causes large-scale death of fish eggs. It can ensure that the hatching environment of the fish eggs is not destroyed, and ensure sufficient water intake and normal use of the filter device.

[0035] Subsequently, the sludge in the hatching water falls into the bottom of the filter box 105, and the user operates the control button 103, so that the control button 103 controls the electric push rod 405 at the bottom of the filter box 105 to work, and the electric push rod 405 drives the shielding plate 403 to move, so that the shielding plate 403 is away from the surface of the discharge hole 404, so that the sludge inside the filter box 105 can pass through the discharge hole 404 into the interior of the discharge port 402, and then enter the interior of the collection frame 401 through the discharge port 402. Under the action of the collection frame 401, the sludge is collected and processed in a centralized manner. Then, the user pulls the baffle door 104 to remove the baffle door 104 from the surface of the fixed box 101, and then pulls the collecting frame 401 to pull the collecting frame 401 out from the inside of the fixed box 101, and processes the sludge inside the collecting frame 401 to realize the sludge processing function of the filtering device, so that the filtering device can process the sludge inside the filter box 105 when in use, and the filtering device can regularly clean and process the sludge inside the filter box 105 when in use, so that the use effect of the filtering device is better, and finally the use of the filtering device is completed.
