[0029] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0030] First embodiment

[0031] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic structural diagram of a first embodiment of a medical wastewater pretreatment device provided by the present invention; Figure 2 for Figure 1 A medical wastewater pretreatment device comprises:

[0032] A box body 1, wherein a cover plate 2 is provided on the top of the box body 1;

[0033] A driving device 3, wherein the driving device 3 is arranged on the surface of the cover plate 2;

[0034] A moving component 5 is arranged inside the box body 1, and the moving component 5 includes a threaded sleeve 51, and both sides of the threaded sleeve 51 are connected to connecting blocks 52, the surface of the threaded sleeve 51 is connected to a hydraulic telescopic rod 53, the top of the hydraulic telescopic rod 53 is connected to a connecting plate 54, both sides of the bottom of the connecting plate 54 are connected to connecting rods 55, and a filter box 56 is connected between the two connecting rods 55.

[0035] The threaded sleeve 51 is threadedly connected to the surface of the threaded rod 33. The coordinated operation of the hydraulic telescopic rod 53 and the connecting plate 54 with two connecting rods 55 can lift the filter box 56 upward after cleaning the suspended matter, which can play a role in solid-liquid separation. The two fixed blocks 31 are symmetrically connected to the surface of the cover plate 2 and are located at both ends of the rectangular connecting groove 4. The motor 32 is a servo motor. The thread on the surface of the threaded rod 33 is a reverse thread. The threaded sleeves 51 are threadedly connected on both sides of the surface of the threaded rod 31, and a partition block is arranged at the center of the surface of the threaded rod 33.

[0036] The driving device 3 includes two fixed blocks 31, wherein a motor 32 is fixedly mounted on one side of one of the fixed blocks 31, one end of the output shaft of the motor 32 is fixedly connected to a threaded rod 33 via a coupling, and one end of the threaded rod 33 is rotatably connected to one side of the other fixed block 31 via a rotating shaft.

[0037] A rectangular connecting groove 4 is provided at the center of the surface of the cover plate 2 .

[0038] The use of the rectangular through-channel 4 facilitates the movement of the movable component 5 .

[0039] A feeding pipe 7 and a discharging pipe 6 are respectively arranged on both sides of the surface of the box body 1 .

[0040] The feeding pipe 7 is installed above the side of the box body 1, and the discharging pipe 6 is installed below the side of the box body 1.

[0041] The working principle of a medical wastewater pretreatment device provided by the present invention is as follows:

[0042] When in use, when pre-treating wastewater, the wastewater is transported to the interior of the box body 1 through the feeding pipe 7 on one side of the box body 1, and then the motor 32 is started to drive the threaded rod 33 to rotate. When the threaded rod 33 rotates, it drives the threaded sleeves 51 on both sides of the surface to move to both sides. When the threaded sleeve 52 moves, it drives the filter box 56 to move to the side of the box body 1 through the connecting rod 55. When the filter box 56 moves, the suspended matter in the wastewater is cleaned. After the suspended matter is cleaned to the interior of 56 and moved to the side of the box body 1, the motor 32 is started, and then the hydraulic telescopic rod 53 is started to drive the connecting rods 55 on both sides to move upward through the connecting plate 54. When the two connecting rods 55 move upward, they drive the filter box 56 to move downward. When the filter box 56 moves to a suitable position, the hydraulic telescopic rod 53 is stopped, and then the pre-treated wastewater inside the box body 1 can be discharged through the discharge pipe 6.

[0043] Compared with the related art, the medical wastewater pretreatment device provided by the present invention has the following beneficial effects:

[0044] The present invention provides a medical wastewater pretreatment device. A driving device 3 is arranged on the surface of a cover plate 2 to cooperate with a moving component 5 inside a box body 1 to operate. When the suspended matter is cleaned, the suspended matter can be lifted upward and separated from the liquid, thereby preventing blockage when discharging the liquid and also improving the cleanliness of the inside of the box body 1.

[0045] Second embodiment

[0046] Please refer to Figure 3 and Figure 4Based on the medical wastewater pretreatment device provided in the first embodiment of the present application, the second embodiment of the present application proposes another medical wastewater pretreatment device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0047] Specifically, the difference of the medical wastewater pretreatment device provided in the second embodiment of the present application is that, in a medical wastewater pretreatment device, a collecting component 8 is provided on one side of the box body 1, and the collecting component 8 includes a collecting box 81, and a positioning block 82 is connected to one side of the collecting box 81, and a positioning groove 83 adapted to the positioning block 82 is opened on one side of the box body 1.

[0048] The use of the positioning block 82 and the positioning groove 83 can play a positioning role when the collection box 81 is installed. A through groove is opened between the box body 1 and the collection box 81 to facilitate the transportation of suspended matter.

[0049] A moving assembly 9 is arranged between the front and rear inner walls of the box body 1, and the moving assembly 9 includes two slide grooves 91, and a slider 92 is slidably connected inside the two slide grooves 91. A fixing rod 93 is connected to one side of the slider 92, and a fixing ring 94 is sleeved on the surface of the fixing rod 93.

[0050] The bottom of the fixing ring 94 is connected to a scraper 95 via a connecting block.

[0051] The working principle of a medical wastewater pretreatment device provided by the present invention is as follows:

[0052] When in use, when the filter box 56 moves upward and contacts the bottom of the scraper 95, the hydraulic telescopic rod 53 works at the same time, and then the slider 92 is driven to move inside the slide groove 91 by pulling the fixed rod 93. When the slider 92 moves inside the slide groove 91, it drives the scraper 95 to drop the suspended matter inside the filter box 56 through the through groove between the box body 1 and the collection box 81 to the inside of the collection box 81.

[0053] When the collection box 81 is to be cleaned, the collection box 81 is pulled to move to one side, and when the collection box 81 moves, the positioning block 82 is driven to separate from the positioning groove 83 on one side of the box body 1.

[0054] Compared with the related art, the medical wastewater pretreatment device provided by the present invention has the following beneficial effects:

[0055] The present invention provides a medical wastewater pretreatment device. A moving component 9 is arranged inside a box body 1 to cooperate with a collecting component 8 on the side of the box body 1 to centrally treat and dump suspended matter.
