Description

Technical Field

[0001] The utility model belongs to the technical field of medical wastewater purification, and in particular relates to a deep purification device for medical wastewater. Background Art

[0002] Medical wastewater originates from various areas within hospitals, including treatment rooms, laboratories, wards, laundries, and operating rooms. Its composition is extremely complex and contains numerous pathogenic microorganisms (such as bacteria and viruses) and chemical residues. Due to its spatial contamination and the risk of acute and latent infections, this type of wastewater poses a serious threat to public health if discharged without proper disinfection. Therefore, efficient and comprehensive purification of medical wastewater is crucial.

[0003] Currently, most medical wastewater purification solutions rely on the manual addition of chemical reagents to achieve disinfection and purification. However, this method faces significant challenges in practical application:

[0004] 1. Manual feeding is not only inefficient, but also prone to errors, resulting in inaccurate dosage of chemical reagents, thus affecting the purification effect.

[0005] Second, manual operation increases labor costs, and during the operation, workers may be exposed to harmful wastewater and chemical reagents, posing a potential threat to their health.

[0006] 3. Due to the untimely and uncertain nature of manual feeding, it is difficult to ensure the continuity and stability of wastewater treatment, thus affecting the normal operation of the entire treatment system.

[0007] 4. Since wastewater is often in a static state during the treatment process, the diffusion rate of chemical reagents in it is limited, which not only prolongs the time required for purification and disinfection, but may also weaken the disinfection effect due to insufficient reaction, thereby reducing the overall treatment efficiency.

[0008] Therefore, in order to solve the above problems, it is necessary to design a deep purification device for medical wastewater. Utility Model Content

[0009] The utility model aims to provide a deep purification device for medical waste water to solve the technical problem of low efficiency of manual feeding.

[0010] In order to solve the above technical problems, the utility model provides a deep purification device for medical wastewater, comprising:

[0011] A purification box with a box cover on the top;

[0012] A water inlet pipe provided with a first solenoid valve is connected to one side of the purification box and is used to control the inflow of wastewater;

[0013] A feeding pipe provided with a second electromagnetic valve is connected to the box cover and is used to feed chemical reagents into the purification box;

[0014] The liquid level sensor is embedded in the tank cover and is used to detect the liquid level of wastewater and the mixture of wastewater and chemical reagents in the purification tank and upload it;

[0015] The main control module is electrically connected to the first solenoid valve, the second solenoid valve and the liquid level sensor;

[0016] When the liquid level sensor detects that the wastewater level reaches a preset threshold, the main control module controls the first solenoid valve to close to stop water inflow, and controls the second solenoid valve to open to start adding chemical reagents; and

[0017] When the liquid level sensor detects that the liquid level of the mixed liquid reaches another preset threshold, the main control module controls the second solenoid valve to close to stop adding chemical reagents.

[0018] Furthermore, a drainage pipe is connected to the lower part of one side of the purification box;

[0019] The drain pipe is provided with a third solenoid valve; and

[0020] The third solenoid valve is electrically connected to the main control module;

[0021] The main control module is suitable for controlling the opening and closing of the third solenoid valve.

[0022] Furthermore, a rotating shaft is provided in the purification box;

[0023] The rotating shaft is connected to the box cover bearing;

[0024] At least two first stirring paddles are arranged at equal intervals on the outer bottom of the rotating shaft.

[0025] Furthermore, at least two second stirring paddles are provided at equal intervals on the outer middle portion of the rotating shaft;

[0026] The rotating shaft is suitable for driving the first stirring paddles and the second stirring paddles to rotate when rotating, so as to stir the liquid in the purification box.

[0027] Furthermore, a reducer is provided on the top of the box cover;

[0028] The reducer is connected to the rotating shaft.

[0029] Furthermore, a motor is provided on one side of the reducer;

[0030] The motor is suitable for driving the shaft to rotate through the reducer;

[0031] The motor is electrically connected to the main control module; and

[0032] The main control module is suitable for controlling the start and stop of the motor.

[0033] Furthermore, a support frame is provided at the bottom of the purification box.

[0034] The beneficial effects of the utility model are:

[0035] (1) When wastewater enters the purification tank through the water inlet pipe, the liquid level sensor will detect the liquid level of the wastewater in real time and upload the information to the main control module. When the wastewater level reaches a preset threshold, the main control module will immediately close the first solenoid valve to stop water inflow and open the second solenoid valve to start adding chemical reagents. Subsequently, the liquid level sensor continues to monitor the liquid level of the mixed liquid. When the liquid level of the mixed liquid reaches another preset threshold, the main control module will close the second solenoid valve to stop adding chemical reagents. At this time, the wastewater and the chemical reagents mix and react to carry out subsequent purification treatment steps. Through the above steps, the effect of improving purification efficiency and reducing operating costs is achieved.

[0036] (2) When stirring is required, the main control module sends a start signal to the motor, and the motor starts to run after receiving the signal. The power of the motor is transmitted to the rotating shaft through the reducer, and the rotating shaft drives the first stirring paddles and the second stirring paddles to rotate in the purification box. The rotation of the first stirring paddles and the second stirring paddles causes the mixture of wastewater and chemical reagents to generate vortex and shear force. After the stirring process continues for a certain period of time, the main control module controls the motor to stop running. Through the above steps, sufficient mixing and reaction are achieved to improve the purification efficiency and ensure the purification effect.

When the wastewater level reaches a preset threshold, the main control module will immediately close the first solenoid valve 3 to stop water inlet, and open the second solenoid valve 5 to start adding chemical reagents. Subsequently, the liquid level sensor 7 continues to monitor the liquid level of the mixed liquid. When the liquid level of the mixed liquid reaches another preset threshold, the main control module will close the second solenoid valve 5 to stop adding chemical reagents.
