[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The solid dirt in the flushing sewage is filtered and collected by multiple filters, so that the solid dirt is filtered in the filter. The spray pipe in the arc-shaped groove sprays water to promote the filtration of the flushing sewage (the water acts as a lubricant and flushes the surface of the filter, avoiding the blockage of the filter holes by solid waste and facilitating the downward movement of the solid dirt, thus facilitating the subsequent compression and collection treatment of the solid dirt), improving the treatment efficiency of the device for the flushing sewage; The corresponding filter is moved from the first box body to the second box body through a multi-stage electric push rod. The multiple filters and the arc-shaped guiding part form a continuous and smooth curved surface. The telescopic scraping device and the driving device cooperate to clean the solid waste in the filter to the bottom of the second box body, facilitating the extrusion molding device to compress the solid waste, facilitating the subsequent device to separate the solid and liquid of the dirt, without manual participation, and improving the operation efficiency of the device; The third electric push rod drives the sealing door panel to move, and the first electric push rod drives the pressing plate to descend below the ventilation hole, so that a relatively sealed space is formed among the second box body, the pressing plate, the movable plate, the water-permeable plate and the sealing door panel. The first electric push rod compresses the solid waste and liquid, so that the liquid in the mixture is collected in the water collection tank through the water-permeable plate. The water-permeable plate also plays a role in filtering. Moreover, by repeating the above compression operation (both compressing and dewatering the solid waste and acting as a pump body to facilitate pressurizing the pressurized discharge device), the air can be compressed until the liquid in the water collection tank is fed into the pressurized discharge device, realizing the solid-liquid separation of the dirt. The second electric push rod controls the movement of the movable plate. After the compression is completed, the movable plate is opened to let the compressed waste slide naturally into the solid medical waste recycling box, completing the collection of solid medical waste without manual participation, reducing the risk of occupational exposure of medical workers and safeguarding the life and health of medical workers; The water level sensor monitors the water level height in the fourth box body, and the pressure sensor monitors the air pressure in the fourth box body. The one-way valve plays a role in preventing reverse flow, preventing reverse flow during the compression of the extrusion forming device and ensuring that a high-pressure state cannot be formed in the fourth box body.

A multi-stage electric push rod 43 is arranged between adjacent arc-shaped guiding parts 42 and telescopic scraper devices 44, and the output shaft of the multi-stage electric push rod 43 is fixedly connected to the end face of the filter. The corresponding filter is moved from the first box body 21 into the second box body 41 through the multi-stage electric push rod 43. The multiple filters and the arc-shaped guiding parts 42 form a continuous and smooth curved surface. The telescopic scraper devices 44 and the driving devices 45 cooperate to clean the solid waste in the filter to the bottom of the second box body 41, facilitating the compression treatment of the solid waste by the extrusion forming device 7 and facilitating the subsequent solid-liquid separation treatment of the dirt by the subsequent device without manual participation, improving the operating efficiency of the device.

[0032] The telescopic scraper device 44 includes an upper scraper 441. The top of the upper scraper 441 is provided with a rotating shaft 444.

The end of the output shaft of the first electric push rod 72 is fixedly provided with a pressing plate 73 which is matched with the through hole. A plurality of ventilation holes 74 are uniformly opened on the second box body 41. A square through hole is opened on the bottom plate of the second box body 41 below the second support 71. A water permeable plate 76 is fixedly arranged in the square through hole. A water collecting tank 77 is fixedly arranged below the water permeable plate 76. The water collecting tank 77 is connected with the disinfection device 9 through a second connecting pipe 710. A second electromagnetic valve 711 is arranged on the second connecting pipe 710. One side of the water permeable plate 76 in the square through hole is rotatably installed with a movable plate 75 through a rotating shaft. A second electric push rod 78 is arranged below the movable plate 75. The two ends of the second electric push rod 78 are fixedly connected with the first support 1 and the movable plate 75 respectively through two universal connecting seats 79. A third electric push rod 712 is fixedly arranged above the top plate of the second box body 41 inside the second support 71. A sealing door plate 713 is slidably arranged in the second box body 41 and the end of the sealing door plate 713 is fixedly connected with the output shaft of the third electric push rod 712. The sealing door plate 713 is driven to move by the third electric push rod 712. The first electric push rod 72 drives the pressing plate 73 to descend below the ventilation holes 74, so that a relatively sealed space is formed by the second box body 41, the pressing plate 73, the movable plate 75, the water permeable plate 76 and the sealing door plate 713. The first electric push rod 72 compresses the solid waste and the liquid, so that the liquid in the mixture is collected in the water collecting tank 77 through the water permeable plate 76. The water permeable plate 76 also plays a role of filtering. Moreover, by repeating the above compression operation (both compressing and dehydrating the solid waste and acting as a pump body to facilitate pressurizing the pressurizing discharge device 8), the air can be compressed until the liquid in the water collecting tank 77 is fed into the pressurizing discharge device 8, so that the solid-liquid separation of the dirt is realized. The second electric push rod 78 controls the movement of the movable plate 75. After the compression is completed, the movable plate 75 is opened to allow the compressed waste to slide naturally into the solid medical waste recycling box 10, so that the collection work of the solid medical waste can be completed without manual participation, reducing the risk of occupational exposure of medical workers and safeguarding the life and health of medical workers.

[0034] The pressurized discharge device 8 includes a fourth box body 81. A water level sensor 83 is fixedly arranged inside the fourth box body 81. A cover plate 82 is fixedly arranged on the top of the fourth box body 81. A pressure relief valve 84 is fixedly arranged on the cover plate 82. A pressure sensor 85 is fixedly arranged on the cover plate 82 on one side of the pressure relief valve 84. The water collecting tank 77 is connected to the fourth box body 81 through a third connecting pipe 86. A check valve 87 is arranged on the third connecting pipe 86. The water level sensor 83 is used to monitor the water level height in the fourth box body 81, and the pressure sensor 85 is used to monitor the air pressure in the fourth box body 81. The check valve 87 plays a role in preventing reverse flow, preventing reverse flow when the extrusion forming device 7 compresses, so that a high-pressure state cannot be formed in the fourth box body 81.

[0035] When the device is in use, the flushing sewage is sent from the sewage inlet pipe 3 to the first box body 21. The first electromagnetic valve 28 is opened. The filtered mixed liquid in the fourth box body 81 is sprayed from the spray pipe 26 onto the filter through the first connecting pipe 27 to assist the filter in filtering the flushing sewage. The filtered sewage is sent to the disinfection device 9 through the first drain pipe 29 for disinfection, and then discharged externally through the second drain pipe 91. When more waste is filtered out on the filter, the sewage inlet pipe 3 is closed, and the multi-stage electric push rod 43 is started to move the first filter 22, the second filter 23, and the third filter 24 from the first box body 21 to the second box body 41. The water inlet valve 6 is opened, and water is sent into the second box body 41 through the water inlet pipe 5. The third electric push rod 712 is started to push the sealing door plate 713 to open externally. Then the driving device 45 is started, and then the telescopic scraping device 44 is driven to rotate, and the solid dirt in the filter is gradually swept above the movable plate 75 and the water permeable plate 76. After the sweeping is completed, the third electric push rod 712 is started to drive the sealing door plate 713 to close. The first electric push rod 72 is started to drive the pressing plate 73 to descend to compress the solid dirt and the liquid. The liquid is collected in the water collecting tank 77 through the water permeable plate 76. Then the first electric push rod 72 is reset, and external air enters from the air vent 74. Then the above operations are repeated, and the liquid in the water collecting tank 77 is pressed into the fourth box body 81 through the check valve 87. After the pressure sensor 85 in the pressurized discharge device 8 reaches the set pressure, the first electric push rod 72 returns to the initial position. Then the second electric push rod 78 is started to open the movable plate 75, so that the solid medical waste located above the movable plate 75 slides into the solid medical waste recycling box 10 to complete the collection of the solid medical waste. Finally, the second electromagnetic valve 711 is opened to divert the residual liquid in the water collecting tank 77 to the disinfection device 9. In this way, the liquid generated during the solid compression is collected in the fourth box body 81, and then the high-pressure state in the fourth box body 81 is used to spray the liquid from the spray pipe 26 to assist the filter in filtering, improving the practicability of the device.
