Description

Technical Field

[0001] This utility model relates to the field of medical wastewater treatment, and specifically discloses a device for collecting medical wastewater. Background Technology

[0002] Medical wastewater mainly comes from the sewage discharged from hospital clinics, laboratories, wards, laundry rooms, X-ray rooms, and operating rooms. Its sources and composition are very complex. Hospital wastewater contains a large number of pathogenic bacteria, viruses, and chemical agents, and has the characteristics of spatial pollution, acute infection, and latent infection. Medical wastewater collection devices are required when treating medical wastewater.

[0003] Chinese Patent Publication No. CN216998007U discloses a device for collecting medical wastewater, including a collection box. A movable cover is movably connected to the upper end of the collection box. A servo motor is fixedly connected to the upper surface of the movable cover. A rotating rod is fixedly connected to the output shaft of the servo motor. A filter screen is movably connected to the side surface of the rotating rod. This invention transports wastewater into the collection box through an inlet pipe for storage. Disinfectant is added to the collection box through a dosing port to disinfect the wastewater. The servo motor is activated, driving the rotating rod to rotate. Through a threaded connection, the filter screen rises, actively filtering the wastewater and causing solid impurities in the wastewater to rise until they are removed from the liquid surface, thus completing the filtration. Active filtration of solid impurities through the rising filter screen improves filtration efficiency. The collection box and movable cover are easily separable, facilitating the cleaning of impurities on the filter screen surface.

[0004] In actual use, the above-mentioned device requires frequent disassembly of the movable cover for manual cleaning of solid impurities after the filter screen filters the solid impurities in the water. This is not only time-consuming and labor-intensive, but also has low cleaning efficiency and may result in incomplete removal of residues on the filter screen surface. It also lacks an automatic cleaning function and is inconvenient to use, so it needs to be improved. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-5 A device for collecting medical wastewater includes a base plate 1. A collection box 2 is fixedly mounted on the upper surface of the base plate 1 via support legs. A top cover 201 is mounted on the top of the collection box 2. A first motor 202 is mounted on the top of the top cover 201. A stirring rod 203 is mounted inside the collection box 2 and coaxially fixedly connected to the first motor 202. A filter assembly is located outside the stirring rod 203 inside the collection box 2. The filter assembly includes a fixed cylinder 3 with open upper and lower end faces, a filter cylinder 301, and a discharge pipe 302 with a solenoid valve. The bottom of the fixed cylinder 3 is connected to the filter cylinder 301, and the bottom of the filter cylinder 301 is connected to the discharge pipe 302. The other end of the discharge pipe 302 extends to the bottom of the collection box 2. A cleaning mechanism is provided above the top cover 201. The cleaning mechanism includes a fixed plate 7. A rinsing pipe 701 with multiple nozzles and a brush plate 702 are fixedly mounted sequentially from front to back on the right side wall of the fixed plate 7. A drive mechanism is provided above the top cover 201.

[0025] In this embodiment: medical wastewater and disinfectant enter the collection tank 2 through the feed pipe 2011. The first motor 202 drives the stirring rod 203 to rotate and mix the medical wastewater and disinfectant. At the same time, the filter assembly performs solid-liquid separation of the wastewater. Solid residue is trapped in the filter cartridge 301, while the liquid enters the bottom of the collection tank 2 through the filter cartridge 301. By opening the valve on the drain pipe 205, the liquid is discharged through the drain pipe 205. When the solid residue in the filter cartridge 301 accumulates to a certain extent, the solenoid valve of the discharge pipe 302 can be opened to discharge the residue under gravity. The first motor 202 is started to drive the stirring rod 203 and the scraper 204 to rotate, cleaning the residue adhering to the inner wall of the discharge pipe 302, so as to facilitate the discharge of the residue.

[0026] When cleaning the filter cartridge 301, the third motor 803 is started, driving the screw 801 to rotate, causing the slider 802 to move the fixed plate 7, the flushing pipe 701, and the brush plate 702 downwards. This allows the flushing pipe 701 and the brush plate 702 to move through the through hole 6 into the collection box 2. At the same time, the bristles of the brush plate 702 can contact the outer wall of the filter cartridge 301. One end of the inlet pipe 901 is connected to an external water pipe, and the water pump 9011 is started, which pumps water through the inlet pipe 901 and... The hose 902 supplies water to the flushing pipe 701, causing multiple nozzles on the flushing pipe 701 to spray water to flush the filter cartridge 301. The drive mechanism (composed of the second motor 501, the first bevel gear 5, and the second bevel gear 502) drives the top cover 201 to slide along the limiting plate 401, making the top cover 201 rotatable. This allows the flushing pipe 701 and the brush plate 702 to rotate clockwise around the filter cartridge 301, thus brushing the filter cartridge 301 and achieving automatic cleaning of the filter cartridge 301.

[0027] As a technical optimization of this utility model, the driving mechanism includes vertical plates 4 located on both sides of the collection box 2 and fixedly installed on the upper surface of the base plate 1. On both sides of the two vertical plates 4, a U-shaped limiting plate 401 is detachably installed by bolts. The edge of the top cover 201 is located inside the two limiting plates 401 and is slidably connected to the two limiting plates 401. A first bevel gear 5 is fixedly installed on the upper end of the top cover 201. A second motor 501 is fixedly installed on the outer wall of one of the vertical plates 4. A second bevel gear 502 that is perpendicularly connected to the first bevel gear 5 is fixedly installed at the output end of the second motor 501.

[0028] In this embodiment: by starting the second motor 501 (worm gear motor), the second bevel gear 502 can be driven to rotate. Since the second bevel gear 502 and the first bevel gear 5 are connected by transmission, the first bevel gear 5 and the top cover 201 can be driven to continue to rotate. At the same time, the two limiting plates 401 can restrict the movement direction of the top cover 201, so that the top cover 201 can rotate stably.

[0029] As a technical optimization of this utility model, the outer wall of the top cover 201 is provided with a through hole 6, and the bottom of the fixing plate 7 is fixedly installed with a plug 703 located inside the through hole 6 and adapted to the through hole 6.

[0030] In this embodiment: the through hole 6 can be blocked by moving the plug 703 into the through hole 6.

[0031] As a technical optimization of this utility model, a support plate 8 in the shape of an inverted "U" is fixedly installed on the upper end surface of the top cover 201, located on one side of the fixed plate 7. A third motor 803 is fixedly installed on the top of the support plate 8. The output end of the third motor 803 passes through the upper end of the support plate 8 and is fixedly installed with a screw 801 that is rotatably connected to the top cover 201. A slider 802 that is slidably connected to the inner side wall of the support plate 8 is threadedly connected to the outer side wall of the screw 801. A connecting plate 804 is fixedly installed on the outer side wall of the slider 802. The top of the fixed plate 7 is fixedly connected to the connecting plate 804.

[0032] In this embodiment: by starting the third motor 803 (worm gear motor), the screw 801 rotates and drives the slider 802 to move along the inner wall of the support plate 8. When the slider 802 moves, it can drive the connecting plate 804 to move, and the height of the connecting plate 804 can be adjusted.

[0033] As a technical optimization of this utility model, a vertical rod 9 is fixedly installed on the upper end face of one of the vertical plates 4. A water inlet pipe 901 is provided at the top of the vertical rod 9. A water pump 9011 fixedly installed on the outer wall of the water inlet pipe 901 is installed at the top of the vertical rod 9. The other end of the water inlet pipe 901 is connected to a hose 902 through a rotary joint. The other end of the hose 902 is connected to a flushing pipe 701.

[0034] In this embodiment: by starting the water pump 9011, the water flow from the external pipe is introduced into the hose 902 through the water inlet pipe 901 and the rotating structure, causing the hose 902 to deliver the water flow into the flushing pipe 701. By using a rotating joint, the top cover 201 can be moved to ensure a stable water supply.

[0035] As a technical optimization of this utility model, a scraper 204 that abuts against the discharge pipe 302 is fixedly installed at the bottom of the stirring rod 203, and a drain pipe 205 with a valve is connected to the bottom of the collection box 2 located outside the discharge pipe 302.

[0036] In this embodiment, when the scraper 204 rotates, it is convenient to clean the impurities adhering to the inner wall of the discharge pipe 302.

[0037] As a technical optimization of this utility model, the upper end face of the top cover 201 is connected to the feed pipe 2011.

[0038] In this embodiment: by setting up the feed pipe 2011, it is convenient to add wastewater and disinfectant into the collection box 2.

[0039] The working principle and usage process of this utility model are as follows: The device is electrically connected to an external power supply and a PLC touch screen. During use, medical wastewater enters the collection tank 2 through the feed pipe 2011, and disinfectant is added into the collection tank 2 through the feed pipe 2011. The first motor 202 drives the stirring rod 203 to rotate and mix the medical wastewater and disinfectant. At the same time, the filter cartridge 301 of the filter assembly performs solid-liquid separation of the wastewater. Solid residue is trapped in the filter cartridge 301, while the liquid enters the bottom of the collection tank 2 through the filter cartridge 301. By opening the valve on the drain pipe 205, the liquid is discharged through the drain pipe 205. When the solid residue in the filter cartridge 301 accumulates to a certain extent, the solenoid valve of the discharge pipe 302 can be opened to allow the residue to be discharged under gravity. The first motor 202 is then started to drive the stirring rod 203 and the scraper 204 to rotate, cleaning the residue adhering to the inner wall of the discharge pipe 302, making it easier to discharge the residue.

[0040] When cleaning the filter cartridge 301, the third motor 803 is started, driving the screw 801 to rotate, causing the slider 802 to move the fixed plate 7, the flushing pipe 701, and the brush plate 702 downwards. This allows the flushing pipe 701 and the brush plate 702 to move through the through hole 6 into the collection box 2. At the same time, the bristles of the brush plate 702 can contact the outer wall of the filter cartridge 301. One end of the inlet pipe 901 is connected to an external water pipe, and the water pump 9011 is started, which pumps water through the inlet pipe 901 and... The hose 902 supplies water to the flushing pipe 701, causing multiple nozzles on the flushing pipe 701 to spray water to flush the filter cartridge 301. The drive mechanism (composed of the second motor 501, the first bevel gear 5, and the second bevel gear 502) drives the top cover 201 to slide along the limiting plate 401, making the top cover 201 rotatable. This allows the flushing pipe 701 and the brush plate 702 to rotate clockwise around the filter cartridge 301, thus brushing the filter cartridge 301 and achieving automatic cleaning of the filter cartridge 301.
