A microbial aeration wastewater purification device

Abstract

This utility model discloses a microbial aeration wastewater purification device, relating to the field of wastewater purification technology. It includes a water storage tank, with an air inlet assembly on one side to guide gas flow and a circulation assembly on the other side to maintain water circulation. An anti-clogging aeration assembly is located at the bottom of the water storage tank. In this utility model, the aeration head opening faces downwards, preventing suspended solids stirred up by the water flow from entering the aeration head through the aeration hood, thus avoiding pore blockage and ensuring good aeration effect. After the gas enters the bottom pipe, the air pressure overcomes the spring force to push the sealing ball away. When the air pump is turned off, the spring pushes the sealing ball to the top of the aeration head, where the sealing ball contacts the inner arc-shaped surface of the aeration head to complete the seal, preventing wastewater from flowing into the bottom pipe and extending the maintenance cycle. By engaging a wave-generating hood at the snap-fit ​​joint, the water outlet direction is controlled while maintaining water circulation, which helps the growth and reproduction of microorganisms and reduces the accumulation of harmful substances.

Description

Technical Field

[0001] This utility model belongs to the field of wastewater purification technology, and in particular relates to a microbial aeration wastewater purification device. Background Technology

[0002] Traditional wastewater purification generally uses chemical methods, which are usually complex, costly, and difficult to control in terms of dosage. Nowadays, water purification generally uses microbial degradation, which has the advantages of low cost and strong sustainability. It is particularly suitable for projects such as the treatment and reuse of rural domestic sewage, rivers and natural lakes. Aeration equipment is required in wastewater treatment to increase the oxygen content in the water and promote the reaction.

[0003] Comparing with Chinese Patent Publication No. CN217600459U, an integrated wastewater treatment microporous aeration component is disclosed, including a treatment tank, an aeration mechanism, and a stirring mechanism. The aeration mechanism includes an air outlet pipe, one end of which extends into the interior of the treatment tank. A first aeration branch pipe and a second aeration branch pipe are fixedly connected near the bottom and middle of the air outlet pipe, respectively. Multiple first tubular microporous aerators and second tubular microporous aerators are equidistantly distributed on the first and second aeration branch pipes, respectively. The air outlets of the multiple first tubular microporous aerators and second tubular microporous aerators are arranged opposite to each other. The stirring mechanism includes a first stirring shaft and a second stirring shaft, both of which are rotatably disposed inside the treatment tank. Multiple stirring blades are equidistantly distributed on both the first and second stirring shafts.

[0004] The disadvantage of the above-mentioned patent is that when the aeration mechanism stops operating or the air intake is insufficient, wastewater can easily flow into the aeration branch pipe through the air holes, and pollutants in the water can clog the air outlet. In order not to affect the aeration effect, frequent cleaning and maintenance are required. Utility Model Content

[0005] The purpose of this invention is to provide a microbial aeration wastewater purification device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A microbial aeration wastewater purification device includes a water storage tank. An air intake component for guiding gas flow is provided on one side of the water storage tank, and a circulation component for maintaining water circulation is provided on the other side. An anti-clogging aeration component is provided at the bottom of the water storage tank. The aeration component includes a bottom pipe with a plurality of aeration heads evenly arranged on it. A fine hood is provided at the opening of each aeration head, and a sealing ball is provided at the top of each aeration head. A spring is fixedly installed on the top of the sealing ball.

[0008] Preferably, the air intake assembly includes an air pump, the air pump output end is provided with a filter box, a filter plate is provided on one side of the filter box, and a diverter is provided at the bottom of the filter box.

[0009] Preferably, the circulation component includes a connecting pipe, one end of which is provided with an intercepting net, and the other end of which is connected to a water pump. The output end of the water pump is provided with a bayonet, and a wave generator is attached to the bayonet.

[0010] Preferably, the filter plate is plugged into the filter box.

[0011] Preferably, the sealing ball fits tightly against the inner wall of the aeration head, and the spring is bolted to the bottom tube.

[0012] Preferably, the aeration head has its opening facing downwards, and the aerating shroud is threadedly connected to the aeration head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the aeration head opening faces downwards, so that the suspended matter washed up by the water flow cannot enter the aeration head through the fine hood when it falls, thus avoiding clogging of the air holes and ensuring that the equipment has a good aeration effect.

[0015] 2. In this utility model, the air pump is started to allow gas to enter the bottom pipe. The air pressure overcomes the spring force and pushes the sealing ball away. When the air pump is turned off, the spring pushes the sealing ball to the top of the aeration head. The sealing ball is sealed by contacting the arc-shaped surface inside the aeration head, which prevents wastewater from flowing into the bottom pipe and extends the maintenance cycle.

[0016] 3. In this utility model, by attaching a wave-generating cover at the snap-fit, the direction of water flow can be flexibly controlled while maintaining water circulation, increasing the oxygen content of the water, which helps the growth and reproduction of microorganisms and reduces the accumulation of harmful substances.

[0022] 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.

[0023] Please see Figures 1-4 A microbial aeration wastewater purification device includes a water storage tank 1, an air intake component 2 for guiding gas flow on one side of the water storage tank 1, a circulation component 3 for maintaining water circulation on the other side of the water storage tank 1, and an anti-clogging aeration component 4 at the bottom of the water storage tank 1.

[0024] In this embodiment: the air intake assembly 2 includes an air pump 201, a filter box 202 is provided at the output end of the air pump 201, a filter plate 203 is provided on one side of the filter box 202, and a distribution tank 204 is provided at the bottom of the filter box 202. The filter plate 203 is plugged into the filter box 202. A clean filter plate 203 is inserted into the filter box 202 in advance. The air pump 201 draws gas into the filter box 202, passes through the filter plate 203 and enters the distribution tank 204. The distribution tank 204 evenly distributes the gas into each bottom pipe 401.

[0025] In this embodiment: the circulation component 3 includes a connecting pipe 301, one end of which is provided with an intercepting net 302, and the other end of which is connected to a water pump 303. The output end of the water pump 303 is provided with a bayonet 304, and a wave generator 305 is attached to the bayonet 304. By twisting the wave generator 305 around the bayonet 304, the flow direction of the circulating water is adjusted. The water pump 303 draws water from the water storage tank 1, which flows in from the intercepting net 302 and flows out from the wave generator 305, maintaining the circulation of the water, increasing the oxygen content, and helping the growth and reproduction of microorganisms.

[0026] In this embodiment: the aeration assembly 4 includes a bottom pipe 401, on which a plurality of aeration heads 402 are evenly arranged. A fine hood 403 is provided at the opening of the aeration head 402, and a sealing ball 404 is provided at the top of the aeration head 402. A spring 405 is fixedly provided at the top of the sealing ball 404. The sealing ball 404 is tightly fitted to the inner wall of the aeration head 402. The spring 405 is bolted to the bottom pipe 401. The opening of the aeration head 402 faces downward. The fine hood 403 is threaded to the aeration head 402. The air pressure overcomes the elastic force of the spring 405 and pushes the sealing ball 404... 04. Finally, the gas is discharged into the water from the bottom of the aeration head 402 through the fine hood 403. Since the opening of the aeration head 402 faces downward, the suspended matter washed up by the water flow cannot enter the aeration head 402 through the fine hood 403 when it falls, thus avoiding clogging of the air holes and ensuring that the equipment has a good aeration effect. When the air pump 201 is turned off, the spring 405 pushes the sealing ball 404 to the top of the aeration head 402. The sealing ball 404 contacts the arc-shaped surface inside the aeration head 402 to complete the seal, preventing wastewater from flowing into the bottom pipe 401 and extending the maintenance cycle.

[0027] Working principle: Clean filter plates 203 are inserted into the filter box 202 beforehand. The wave generator hood 305 is rotated around the bayonet 304 to adjust the flow direction of the circulating water, discharging the wastewater to be treated into the storage tank 1. The air pump 201 draws gas into the filter box 202, passes through the filter plates 203, and enters the distribution tank 204. The distribution tank 204 evenly distributes the gas to each bottom pipe 401. The air pressure overcomes the elastic force of the spring 405, pushing the sealing ball 404 away. Finally, the gas is discharged into the water from the bottom aeration hood 403 of the aeration head 402. Simultaneously, the water pump 303 draws water from the storage tank 1. The water flows in through the interceptor 302 and out through the wave generator 305, maintaining water circulation, increasing oxygen content, and promoting the growth and reproduction of microorganisms. Since the aeration head 402 has its opening facing downwards, suspended solids lifted by the water flow cannot enter the aeration head 402 through the fine hood 403 when they fall, preventing pore blockage and ensuring good aeration effect. When the air pump 201 is turned off, the spring 405 pushes the sealing ball 404 to the top of the aeration head 402, and the sealing ball 404 contacts the arc-shaped surface inside the aeration head 402 to complete the seal, preventing wastewater from flowing into the bottom pipe 401 and extending the maintenance cycle.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
