[0021] The cleaning mechanism 6 includes a wrapping plate 601, a rotating groove 602, a rotating plate 603, a gear groove 604, a rubber ring 605, a gear 606, a connecting shaft 607, a motor 608, a support frame 609, a bevel plate 610 and a bristle brush 611.

A rubber ring 605 is provided on the inner side of the rotating disk 603, a gear 606 is provided on the outer side of the surface of the gear groove 604, a connecting shaft 607 is fixedly connected to one side surface of the gear 606, one end of the connecting shaft 607 is fixedly connected to a motor 608, a support frame 609 is fixedly connected to one side surface of the wrapping disk 601, a beveled disk 610 is fixedly connected to one side surface of the rotating disk 603, a bristle brush 611 is fixedly connected to one side surface of the beveled disk 610, and a bristle brush 611 is fixedly connected to one side surface of the wrapping disk 601. The housing 1 is connected with a funnel 612, through the arrangement of the wrapping plate 601, the rotating groove 602, the rotating plate 603, the gear groove 604, the rubber ring 605, the gear 606, the connecting shaft 607, the motor 608, the support frame 609, the bevel plate 610 and the bristle brush 611, when it is necessary to clean the inner wall of the housing 1, the motor 608 is first turned on, and then the motor 608 drives the connecting shaft 607 to rotate, and then the connecting shaft 607 drives the gear 606 to rotate, at this time, through the gear 606 and The gear groove 604 is meshedly connected, thereby driving the rotating disk 603 to rotate in the rotating groove 602. When the rotating disk 603 rotates, it will drive the bevel disk 610 to rotate, and the bevel disk 610 will drive the bristle brush 611 to rotate. When the bristle brush 611 rotates, it will scrub the inside of the shell 1, so that the scrubbed stains flow into the funnel 612 through the bevel disk 610, and then flow into the sand storage box 5 through the funnel 612, so that the inner wall of the shell 1 can be cleaned.

[0022] Furthermore, the base frame 2 is provided with four pillars, and the rotating disk 603 and the rubber ring 605 are fitted together. Through the setting of the base frame 2, the stability of the device can be better, and the device will not cause shaking or collapse during operation. Through the setting of the rotating disk 603 and the rubber ring 605, liquid leakage can be prevented from occurring, which may cause the gear 606 to rust and hinder the operation of the machine.

[0023] Furthermore, the inner side of the gear slot 604 and the outer side surface of the gear 606 are meshed with each other, and the motor 608 and the support frame 609 are fixedly connected. Through the setting of the gear slot 604 and the gear 606, the rotating disk 603 can be rotated better, thereby driving the bevel disk 610 to rotate. Through the setting of the motor 608 and the support frame 609, the motor 608 can be fixed so that the motor 608 will not shake or rotate the shell 1 during movement, making the operation of the device more stable.

[0024] Furthermore, the slope of the outer surface of the funnel 612 is in contact with the bevel disk 610, and six groups of bristle brushes 611 are arranged on the bevel disk 610. Through the arrangement of the funnel 612 and the bevel disk 610, the gravel can slide downward better without clogging the gravel, so that the device can operate better. Through the arrangement of the bristle brushes 611 on the bevel disk 610, the gravel on the inner wall of the outer shell 1 can be better cleaned, and multiple brushing increases the work efficiency. At the same time, the distribution of the six groups of bristle brushes 611 will not affect the effect of centrifugal force.

[0025] Furthermore, the filtering mechanism 7 includes a filter mesh 701, a water filter trough 702, a fixed plug 703 and a sand storage trough 704. The filter mesh 701 is arranged inside the water inlet pipe 3, the filter trough 702 is opened inside the water inlet pipe 3, the fixed plug 703 is threadedly connected to the water inlet pipe 3, and a sand storage trough 704 is opened on one side surface of the fixed plug 703. Through the arrangement of the filter mesh 701, the filter trough 702, the fixed plug 703 and the sand storage trough 704, when sewage enters the water filter trough 702 through the water inlet pipe 3, the filter mesh 701 will intercept larger sand and gravel to achieve pretreatment, so that it passes through the interception of the filter mesh 701 and flows into the sand storage trough 704 inside the fixed plug 703. When it is necessary to replace the filter mesh 701 and pour out the sand in the sand storage trough 704, the fixed plug 703 is unscrewed from the water inlet pipe 3 so that the internal sand and gravel can be poured out and the filter mesh 701 can be replaced.

[0026] Furthermore, the outer surface of the filter mesh 701 is in contact with the inner wall of the water inlet pipe 3. By configuring the filter mesh 701 and the water inlet pipe 3, sewage can be better filtered so that larger gravel can be filtered out.

[0027] Furthermore, one end of the filter mesh 701 is fitted with the fixed plug 703. Through the setting of the filter mesh 701 and the fixed plug 703, the sand and gravel filtered by the filter mesh 701 can flow into the sand storage tank 704 better. At the same time, the fixed plug 703 can also support the filter mesh 701 to prevent it from shaking, and it is also convenient to replace the filter mesh 701.

[0028] Working principle: First, when sand removal is required, the water inlet pipe 3 and the water outlet pipe 4 are connected to the main device, and then the sewage is discharged. When the sewage enters the filter tank 702 through the water inlet pipe 3, it will pass through the filter screen 701 for pretreatment, and then the filter screen 701 will filter out larger gravel, so that the gravel falls into the sand storage tank 704 along the filter screen 701, and then the pretreated sewage enters the interior of the outer shell 1. Due to the action of the pipeline stamping, the sewage will pass through the centrifugal force along the inside, so that the heavier gravel will slide down along the inner wall of the outer shell 1, and then it will slide along the inner wall of the outer shell 1 to the funnel 612, and then to the sand storage box 5 for storage. After the centrifugal force, the sewage will be adsorbed upward along the outlet pipe 4 and flow out. Shell 1, when the machine removes sand, the inner wall of the shell 1 will be stuck with a lot of gravel, which needs to be processed. First, turn on the motor 608, and then the motor 608 drives the connecting shaft 607 to rotate, and then the connecting shaft 607 drives the gear 606 to rotate. At this time, the gear 606 and the gear groove 604 are engaged and connected, thereby driving the rotating disk 603 to rotate in the rotating groove 602. When the rotating disk 603 rotates, it will drive the bevel disk 610 to rotate, and the bevel disk 610 will drive the bristle brush 611 to rotate. When the bristle brush 611 rotates, it will scrub the inside of the shell 1, so that the scrubbed stains flow into the funnel 612 through the bevel disk 610, and then flow into the sand storage box 5 through the funnel 612, so that the inner wall of the shell 1 is cleaned.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
