Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology and relates to an aeration device for hospital wastewater treatment. Background Technology

[0002] Hospitals generate large amounts of medical wastewater and domestic sewage during their operations and daily life. Wastewater requires treatment before discharge. Aeration is a crucial step in wastewater treatment; it involves introducing air or oxygen into the wastewater to increase contact between the wastewater and oxygen, ensuring that microorganisms in the treatment tank have sufficient dissolved oxygen to oxidize and decompose the organic matter in the wastewater.

[0003] To improve the contact between oxygen and water, a multi-microporous device is usually installed at the bottom of the water body, connected to an air pump, allowing gas to diffuse through the micropores. However, due to the large number of solid particles in wastewater, long-term use may cause blockage at the oxygen release points of the aeration device. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes an aeration device for hospital wastewater treatment, which effectively solves the issues in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An aeration device for hospital wastewater treatment includes:

[0007] A water storage tank, wherein an inlet and an outlet are provided at both ends of the water storage tank;

[0008] A diffuser, wherein the upper end of the diffuser is provided with multiple micropores and the diffuser is provided with an air inlet pipe;

[0009] Valve cores, with multiple valve cores installed one-to-one in the micropores;

[0010] An air pump, the output end of which is connected to the air inlet of the diffuser;

[0011] A circulation pump, the output end of which is fixedly installed at the upper end of the water tank, and the input end of which is fixedly connected to the bottom of the water tank.

[0012] Optionally, the diffuser includes:

[0013] The valve core and the intake manifold are located in the recessed portion;

[0014] The buoyancy part is fixedly installed on the sinking part, and the buoyancy part is an airbag;

[0015] A pressure relief valve, wherein the input end of the pressure relief valve is connected to the air inlet pipe and the output end is connected to the upper floating part;

[0016] An exhaust valve is fixedly installed on the upper floating part.

[0017] Optionally, the air intake pipe is a flexible hose.

[0018] Optionally, the valve core is threaded into the micropore.

[0019] Optionally, a plurality of sliding rods are fixedly installed at the bottom of the water tank, and a sliding hole is provided in the middle of the diffuser, and the diffuser is slidably installed on the sliding rods respectively.

[0020] Optionally, a horn-shaped pipe is provided at the bottom of the water storage tank, with the large-diameter end of the horn-shaped pipe connected to the bottom of the water storage tank and the small-diameter end of the horn-shaped pipe connected to the circulation pump.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting a one-way valve core as the structure for venting gas, the exhaust position is automatically closed when no gas is vented, reducing the possibility of solid particles clogging the exhaust position, and increasing the circulation of the circulation pump to reduce the settling of solid particles, further reducing the possibility of solid particles clogging the exhaust position;

[0023] 2. By setting up a pressure relief valve and an upward floating section, when a blockage occurs at the upper end of the diffuser, the pressure in the intake pipe increases, the pressure relief valve opens, and gas enters the upward floating section. The volume of the upward floating section expands, increasing the buoyancy of the diffuser and causing the diffuser to float, making it easier to detect and repair the diffuser.

[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 and Figure 2 This utility model discloses an aeration device for hospital wastewater treatment, comprising a water tank 1, with an inlet and an outlet at both ends of the water tank 1, a plurality of diffusers 2 at the bottom of the water tank 1, a plurality of micropores at the upper end of the diffusers 2, an air inlet pipe 201 at the diffusers 2, and valve cores 3 installed on the micropores. An air pump 4 and a circulation pump 5 are arranged on the outside of the water tank 1, the output end of the air pump 4 is connected to the air inlet end of the diffusers 2, the output end of the circulation pump 5 is fixedly arranged at the upper end of the water tank 1, and the input end of the circulation pump 5 is fixedly connected to the bottom of the water tank 1.

[0029] Specifically, the water storage tank 1 collects and releases hospital sewage through the inlet and outlet. A diffuser 2 is installed in the water storage tank 1, and the diffuser 2 is connected to an air pump 4. The air pump 4 supplies air to the diffuser 2, so that the gas is discharged from the micropores and comes into contact with the hospital sewage. A valve core 3 is installed in the micropores. The valve core 3 is unidirectional. The water storage tank 1 is also connected to a circulation pump 5 to increase the water flow in the water storage tank 1.

[0030] In this way, by setting the unidirectional valve core 3 as the structure for venting gas, the exhaust position is automatically closed when no gas is vented, reducing the possibility of solid particles clogging the exhaust position, and increasing the circulation of the circulation pump 5 to reduce the settling of solid particles, further reducing the possibility of solid particles clogging the exhaust position.

[0031] In some feasible configurations, the water tank 1, inlet, and outlet are configured according to actual needs. The diffuser 2 is disc-shaped with a hollow interior. Micropores are located at the upper end of the diffuser 2. The valve core 3 is existing technology, often used for bicycle tire inflation. Its basic structure includes a circular tube with radial openings, one end of which is sealed, and the other end connected to the micropores. An elastic rubber ring is fitted at the radial opening. When there is no gas pressure, the rubber ring seals the radial opening; when there is gas pressure, the gas expands the elastic rubber ring and is discharged through the radial opening. The air pump 4 can be an air compressor pump or can supply oxygen directly from an oxygen cylinder to increase the oxygen content.

[0032] As a specific embodiment of an aeration device for hospital wastewater treatment provided in the application, the diffuser 2 includes a submerged part 21 and an upward floating part 22. The valve core 3 and the air inlet pipe 201 are disposed in the submerged part 21, and the upward floating part 22 is fixedly installed in the submerged part 21. The upward floating part 22 is an air bag. The air inlet pipe 201 is connected to a branch pipe, and the branch pipe is connected to a pressure relief valve 23. The output end of the pressure relief valve 23 is connected to the upward floating part 22, and the upward floating part 22 is provided with an exhaust valve.

[0033] Overall, by setting up the pressure relief valve 23 and the floating part 22, when the upper end of the diffuser 2 is blocked, the pressure in the intake pipe 201 increases, the pressure relief valve 23 opens, and the gas enters the floating part 22. The volume of the floating part 22 expands, increasing the buoyancy of the diffuser 2 and causing the diffuser 2 to float, so as to facilitate the detection and repair of the diffuser 2.

[0034] Furthermore, the valve core 3 is threaded into the micro-hole.

[0035] It should be understood that the threaded connection facilitates the disassembly and replacement of the valve core 3.

[0036] Furthermore, multiple sliding rods 6 are fixedly installed at the bottom of the water tank 1, and a sliding hole is provided in the middle of the diffuser 2. The diffuser 2 is slidably installed on the sliding rods 6.

[0037] It should be understood that by setting the slide bar 6 and the sliding hole, the diffuser 2 is made to rise along a predetermined path during the upward process, reducing the possibility of it floating randomly.

[0038] In some feasible configurations, the submerged portion 21 is annular, with its bottom outer side extending downwards to form a accommodating space for the floating portion 22. The floating portion 22 is a commonly used inflatable airbag, folded and compressed, and placed at the bottom of the submerged portion 21. The submerged portion 21 has a certain weight, causing the diffuser 2 to sink. The sliding rod 6 is a cylindrical rod fixedly installed at the bottom of the water tank 1. To facilitate the floating of the diffuser 2, the air inlet pipe 201 is a flexible hose. The exhaust valve can be set as a manual air valve.

[0039] To improve control of diffuser 2, pressure relief valve 23 includes a solenoid valve mounted on a branch pipe. The solenoid valve is connected to a differential pressure switch. The high-pressure side of the differential pressure switch is connected to the sinker 21, and the low-pressure side is connected to the atmosphere. When the pressure difference exceeds a set value, the differential pressure switch is triggered, causing the solenoid valve to actuate and opening the floating section 22 for inflation. Simultaneously, the solenoid valve can also be controlled by a control switch, allowing diffuser 2 to float actively and controllably, further facilitating maintenance.

[0040] As another specific embodiment of the aeration device for hospital wastewater treatment provided in the application, a bell pipe 11 is provided at the bottom of the water tank 1, with the large-diameter end of the bell pipe 11 connected to the bottom of the water tank 1 and the small-diameter end of the bell pipe 11 connected to the circulating pump 5.

[0041] Based on the specific application scenario, by setting up the horn tube 11, it is convenient to circulate the water in a larger area at the bottom of the water tank 1, thereby improving the uniformity of contact between the water and the gas in the diffuser 2.

[0042] In some feasible methods, a circular pipe is fixedly installed on the top of the water tank 1, and multiple openings are provided at the bottom of the circular pipe. The output end of the circulation pump 5 is connected to the circular pipe.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
