Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically, it relates to an emergency treatment device for medical wastewater. Background Technology

[0002] Medical wastewater refers to sewage discharged by hospitals into the natural environment or urban pipelines. The main pollutants contained in medical wastewater include pathogens, organic matter, floating and suspended solids, and radioactive pollutants. Without effective treatment, it can become an important route for the spread of disease and seriously pollute the environment.

[0003] Medical wastewater contains solid waste such as used cotton swabs, gauze, and masks, which are covered with a large number of pathogens. To avoid infection from direct contact, these wastes need to be centrally processed. However, existing treatment devices simply pump the wastewater away without effectively separating the solid waste, resulting in incomplete treatment of the wastewater in subsequent processes.

[0004] Patent CN216737975U discloses an emergency treatment device for medical wastewater. The wastewater treatment device is divided into three stages: the first stage is used for preliminary solid-liquid separation of wastewater; the second stage is used to further remove solid impurities and purify water quality through activated sludge method; and the third stage is used to separate sludge and liquid water, disinfect the wastewater, and then discharge it.

[0005] However, the emergency treatment device for medical wastewater in this patent has the following drawbacks: the emergency treatment device discharges wastewater after sedimentation and disinfection through three-stage treatment; however, when separating solid and liquid wastewater, the solid waste is not centrally treated and disinfected, and the solid waste in the medical wastewater is only isolated by a screen, resulting in the separated solid waste still containing a high proportion of wastewater.

[0006] In the technical solutions of the aforementioned patents, although the emergency treatment device achieves disinfection and other treatments for wastewater, it does not take into account the problem that solid waste will adsorb wastewater, leading to incomplete treatment when treating solid waste. Utility Model Content

[0007] To address the technical problem in existing technologies where emergency treatment devices for solid waste neglect the adsorption effect of solid waste on wastewater, resulting in incomplete wastewater treatment, this utility model provides an emergency treatment device for medical wastewater.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] An emergency treatment device for medical wastewater includes a filter tank and a high-temperature drying and disinfection box installed at one end of the filter tank; a fixed block is provided on the filter tank, and a bidirectional screw is provided between the fixed blocks, with a sliding block connected to the bidirectional screw; a clamping plate is provided at the bottom of the sliding block, and a cylinder is provided on the other end of the filter tank away from the high-temperature drying and disinfection box, with the output end of the cylinder passing through the filter tank and connected to a push plate.

[0010] Furthermore, the fixing block is located in the middle of the upper surface of the filter tank, one end of the bidirectional lead screw is connected to the motor, and the other end of the bidirectional lead screw is rotatably connected to the fixing block on the opposite side of the motor; the bidirectional lead screw is threadedly connected to the sliding block.

[0011] Furthermore, the filter pool is equipped with a filter screen inside, which divides the filter pool into an upper chamber and a lower chamber.

[0012] Furthermore, a sedimentation and disinfection tank is provided on one side of the filtration tank, and an electromagnetic door is provided at one end of the filtration tank.

[0013] Furthermore, the pusher plate is located on the upper surface of the filter screen and between the two clamping plates.

[0014] Furthermore, the bottom of the push plate is provided with a groove cavity, and a brush roller is provided in the groove cavity. The brush roller has a cylindrical structure, and the two ends of the brush roller are connected to the two ends of the push plate. The brush roller is located at the bottom of the push plate and contacts the filter screen.

[0015] Furthermore, one end of the brush roller passes through the push plate and is connected to a gear. The bottom of the gear is engaged with a toothed rack. A groove is provided on the filter screen near the gear, and the toothed rack is located in the groove of the filter screen.

[0016] The beneficial effects of this utility model are:

[0017] This invention utilizes a motor to drive a sliding block to move relative to a bidirectional lead screw. The sliding block, in turn, moves clamping plates relative to each other, compressing the filtered solid waste between the two clamping plates and reducing the proportion of wastewater in the solid waste. Then, a cylinder drives a pusher plate to move, pushing the solid waste from the filter screen into a high-temperature drying and disinfection chamber for drying and disinfection until it meets emission standards before being discharged. This reduces the proportion of wastewater in the solid waste, enabling independent treatment of wastewater and centralized disposal of solid waste to prevent further interference with the wastewater treatment process and reduce the risk of solid waste spreading pathogens.

[0018] This invention uses a cylinder to retract a push plate, and a gear at the bottom of the push plate rotates on a gear rack. The gear drives a brush roller to rotate, which cleans the blockages on the filter screen and prevents the filter screen from clogging, so that the medical wastewater can be filtered and treated subsequently.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 , Figure 2 and Figure 3 As shown, an emergency treatment device for medical wastewater includes a filter tank 1 and a high-temperature drying and disinfection box 2 installed at one end of the filter tank 1.

[0029] The filter tank 1 has a rectangular structure. Symmetrical fixing blocks 101 are fixedly installed on both sides of the middle of the upper surface of the filter tank 1. A bidirectional lead screw 8 is provided between the two fixing blocks 101. One end of the bidirectional lead screw 8 is connected to the motor 4. The output end of the motor 4 passes through the fixing block 101 and is connected to one end of the bidirectional lead screw 8. A support block 401 is provided at the bottom of the motor 4. The other end of the bidirectional lead screw 8 is rotatably connected to the fixing block 101 on the opposite side of the motor 4. Symmetrical sliding blocks 7 are threaded on the bidirectional lead screw 8. The support block 401 provides support force to the motor 4 and is used to fix the motor 4.

[0030] By turning on the motor 4, the sliding block 7 moves relative to the bidirectional lead screw 8, causing the push plates 11 on both sides to move towards the center of the filter tank 1, thus squeezing the solid waste on the filter screen 9.

[0031] The filter tank 1 is equipped with a filter screen 9, which divides the filter tank 1 into an upper chamber and a lower chamber. When medical wastewater is discharged into the filter tank 1, the wastewater is discharged into the lower chamber of the filter tank 1 under the action of the filter screen 9, while solid waste is in the upper chamber of the filter tank 1.

[0032] A sedimentation and disinfection tank 3 is provided on the side of the filter tank 1 away from the motor 4. The filter tank 1 and the sedimentation and disinfection tank 3 are discharged through a water pipe, and a valve is installed on the water pipe to control the flow of wastewater.

[0033] The filtered wastewater is discharged into sedimentation and disinfection tank 3 for further sedimentation and disinfection until it meets the discharge standards before being discharged.

[0034] Both sliding blocks 7 are provided with clamping plates 10 at their bottoms. The clamping plates 10 are located at the end of the sliding block 7 near the inner wall of the filter tank 1. The bottom of the clamping plates 10 is in contact with the filter screen 9.

[0035] The motor 4 drives the bidirectional lead screw 8 to rotate, and the sliding block 7 on the bidirectional lead screw 8 moves relative to each other. The sliding block 7 drives the clamping plate 10 to move relative to each other, so that the filtered solid waste is squeezed between the two clamping plates 10, reducing the proportion of wastewater in the solid waste, so as to facilitate the subsequent drying and disinfection of the solid waste.

[0036] A cylinder 5 is provided on the filter pool 1 at the other end away from the high-temperature drying and disinfection box 2. The output end of the cylinder 5 passes through the filter pool 1 and is connected to the push plate 11. The push plate 11 is located on the upper surface of the filter screen 9 and between the two clamping plates 10.

[0037] Please see Figure 4 and Figure 5 As shown, the bottom of the push plate 11 near the cylinder 5 is provided with a groove 12, and a brush roller 13 is provided in the groove 12. The brush roller 13 has a cylindrical structure, and the two ends of the brush roller 13 are connected to the two ends of the push plate 11. The brush roller 13 is located at the bottom of the push plate 11 and contacts the filter screen 9.

[0038] One end of the brush roller 13 passes through the push plate 11 and connects to the gear 14. The bottom of the gear 14 is engaged with a toothed rack 15. The filter screen 9 near the gear 14 has a groove, and the toothed rack 15 is located in the groove of the filter screen 9.

[0039] The cylinder 5 drives the push plate 11 to retract, and the gear 14 at the bottom of the push plate 11 rotates on the gear rack 15. The gear 14 drives the brush roller 13 to rotate. The brush roller 13 is used to clean the blockage on the filter screen 9 so that the medical wastewater can be filtered and treated later.

[0040] By opening cylinder 5, the filtered solid waste on push plate 11 is pushed towards one end of the high-temperature drying chamber. Then, the electromagnetic door 6 is opened, pushing the solid waste into the high-temperature drying and disinfection chamber 2 for drying and disinfection.

[0041] Furthermore, an electromagnetic door 6 is provided on the filter pool 1 near the high-temperature drying and disinfection chamber 2. Similarly, an electromagnetic door 6 is provided on the high-temperature drying and disinfection chamber 2 near the filter pool 1. When the push plate 11 pushes the solid waste on the filter screen 9 to the electromagnetic door 6 10-15cm, the electromagnetic lock power is controlled to open the electromagnetic door 6, pushing the solid waste into the high-temperature drying and disinfection chamber 2 for drying and disinfection until the emission standards are met before discharge.

[0042] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0043] First, the medical wastewater is discharged into the filter tank 1. After filtration, the motor 4 is turned on, causing the sliding block 7 to move relative to the double-acting screw 8. The sliding block 7 drives the clamping plate 10 to move relative to each other, so that the filtered solid waste is squeezed between the two clamping plates 10, reducing the proportion of wastewater in the solid waste. Then, the motor 4 is reversed, causing the clamping plate 10 to move in the opposite direction.

[0044] Then, cylinder 5 is activated, which drives push plate 11 to move. When push plate 11 pushes the solid waste on filter screen 9 to electromagnetic door 6 at 10-15cm, electromagnetic door 6 is opened, and the solid waste is pushed into high-temperature drying and disinfection chamber 2 for drying and disinfection until the emission standards are met before being discharged.

[0045] The filtered wastewater is discharged into sedimentation and disinfection tank 3 for further sedimentation and disinfection until it meets the discharge standards before being discharged.

[0046] After the discharge is completed, the cylinder 5 drives the push plate 11 to retract. The gear 14 at the bottom of the push plate 11 rotates under the action of the gear rack 15. The gear 14 drives the brush roller 13 to rotate. The brush roller 13 is used to clean the blockage on the filter screen 9 so that the medical wastewater can be filtered and treated in the future.
