Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of waste treatment equipment, in particular to a medical sewage treatment device. Background Art
[0002] Medical wastewater, also known as medical wastewater, refers to liquid waste from hospitals that contains large amounts of pathogenic bacteria, viruses, and chemicals. Existing medical wastewater treatment equipment, due to the varying toxic and hazardous substances contained in the wastewater, requires the use of mixed disinfectants. While agitators are typically designed to accelerate mixing efficiency, these devices are unable to treat glass fragments and other solids and suspended matter mixed in the wastewater. Consequently, even after timely disinfection, separate treatment is still required, which is time-consuming, labor-intensive, and inefficient.
[0003] A search revealed, for example, (Authorization Announcement No. CN215516725U) and an environmentally friendly medical wastewater treatment device, comprising a housing and supporting legs fixedly connected at the four corners of the housing's bottom. A feeding pipe connected to the housing's inner cavity is located on one side of the top of the housing. A shaft is vertically installed in the center of the housing's inner cavity, with one end of the shaft extending through the top of the housing via a sleeve. This device addresses the problem of existing equipment that prevents multiple disinfectants from being fully mixed. However, this device cannot filter out glass fragments and suspended solids contained in the wastewater before treating medical wastewater, which reduces the device's treatment efficiency. Utility Model Content

[0029] Example
[0030] like Figures 1 to 4 As shown,
[0031] This embodiment includes:
[0032] The box body 1 is provided with a funnel-shaped feed hopper 5 on the top of the box body 1, and a sieve plate 6 for primary filtration is provided below the feed hopper 5. The fixed part of the sieve plate 6 is connected to the inner wall of the box body 1, and the sieve plate 6 is arranged obliquely inside the box body 1. A screening net 10 is installed inside the sieve plate 6. The screening net 10 can filter the medical waste water entering the feed hopper 5 and clean the solids and suspended matter contained in the waste water. A linear motor 11 arranged parallel to the sieve plate 6 is fixed on the inner wall of the box body 1, and a cleaning plate 19 is fixed to the moving part of the linear motor 11. The cleaning plate 19 is slidably connected to the screening net 10 to assist in cleaning the screening net 10, avoid mesh clogging caused by long-term use, and facilitate use.
[0033] The filter plate 7 for secondary filtration is located below the sieve plate 6, and both the filter plate 7 and the sieve plate 6 are embedded with a screening mesh 10. The end of the filter plate 7 is connected to the inner wall of the box body 1, and the inner bottom of the box body 1 is provided with a discharge port 8 for sewage discharge for initial treatment. The same screening mesh 10 as the sieve plate 6 is installed inside the filter plate 7, but the aperture of the screening mesh 10 inside the filter plate 7 is much smaller than the aperture of the inside of the sieve plate 6, and the filter plate 7 is parallel to the sieve plate 6. Through the action of the screening mesh 10, the glass fragments contained in the medical waste water are filtered to avoid direct dumping during subsequent operations or after treatment, which affects the surrounding area, thereby improving the practicality of the device.
[0034] A plurality of through slots 9 are provided on one side of the box body 1, two of which are connected to the connecting slot 16 and the feed slot 17. The feed slot 17 and the connecting slot 16 are both provided at the end of the processing box 4. The side wall of the processing box 4 is welded to the side wall of the box body 1. Through the provision of the feed slot 17, the solid waste filtered by the cleaning plate 19 and the sieve plate 6 can be collected and enter the interior of the processing box 4 through the feed slot 17.
[0035] A mounting groove is provided on one side of the processing box 4, a filter screen 12 is provided on the side wall of the mounting groove, and a fan 13 is connected to the mounting groove. The air outlet end of the fan 13 is connected to the side wall of the heating box 14, and through-holes 15 are provided on both sides of the heating box 14. The through-holes 15 are evenly spaced to facilitate the air to be blown out through the fan 13.
[0036] A number of heating rods 18 are arranged inside the heating box 14. The heating rods 18 use existing mature structures, such as electromagnetic, resistance and direct heating, to quickly heat up the heating rods 18 and the surrounding air, and cooperate with the fan 13 to complete the drying of the inside of the treatment box 4, so as to prevent the solid waste screened out from the inside of the box 1 from carrying a large amount of liquid and pathogens, and through the connecting groove 16 set at the bottom of the treatment box 4, the air with water vapor is input into the inside of the box 1. A cleaning port is provided at the bottom of the treatment box 4, and the cleaning port can regularly complete the cleaning of the inside of the treatment box 4.
[0037] A collecting box 3 is also provided below the processing box 4. The side wall of the collecting box 3 is connected to the box body 1 and is connected to the through groove 9 through a collecting groove provided on the side wall of the collecting box 3, so as to facilitate the collection of fine solid particle waste such as glass fragments filtered by the filter plate 7. Debris such as glass fragments can automatically gather inside the collecting box 3 under the impact of the liquid and the action of gravity. A collecting groove is also provided at the bottom of the collecting box 3. The collecting groove can be opened and closed and has a good sealing effect, and only needs to be processed regularly.
[0038] A hinged door 2 is provided on one side of the box body 1. The setting of the door 2 can facilitate regular maintenance of the internal structure of the device. A plurality of ultraviolet disinfection lamps with transparent sealing covers are installed on the inner top wall of the box body 1, so that the inside of the device can be disinfected when not treating medical waste water, avoiding cross-infection of pathogens due to maintenance or air circulation, and improving the safety of the device.
[0039] Pipes connected to the box body 1 are provided inside the processing box 4 and the collecting box 3. Hollow mesh plates are set between the two and the waste collection area. The bottom of the mesh plate is connected to the pipe, which can drain the liquid in the filtered debris and improve the drying efficiency and processing effect of the device.
[0040] The linear motor 11 and the fan 13 are both conventional instruments. Their working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail. The linear motor 11 works in a humid environment for a long time, so the linear motor 11 is waterproof and moisture-proof. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in this invention.
[0041] How it works
[0042] The medical wastewater treatment device, when using the device, is placed into the box body 1 through the feed hopper 5, and the moving part of the linear motor 11 is started to move, driving the connected cleaning plate 19 to move, and the sieve plate 6 and the embedded screening net 10 are cleaned. A treatment box 4 is set on one side of the box body 1, and a fan 13 is installed on the side wall of the treatment box 4. A heating box 14 is fixed inside the treatment box 4, and a heating rod 18 is connected to the inner wall of the heating box 14. The side wall of the heating box 14 is provided with through-type through holes 15 arranged at equal intervals, and the fan 13 is used to blow out hot air to complete the drying of the waste inside the treatment box 4.
[0043] Finally, the fine waste filtered by the filter plate 7 is filtered and collected through the filter plate 7 and the screening net 10 inside it, and the screened medical waste is directly put into the wastewater treatment device for treatment, and the collection box 3 and the treatment box 4 are cleaned regularly.
