Description

Technical Field

[0001] This application relates to the field of environmental wastewater purification and treatment technology, specifically to an odor-deodorizing environmental wastewater purification and treatment device. Background Technology

[0002] The deodorizing environmental wastewater purification and treatment device is an air purification and water treatment equipment that integrates wastewater treatment and deodorization functions. It uses physical, chemical or biological methods to remove harmful and odorous substances from wastewater to purify water quality and eliminate odors. It is widely used in the treatment of various types of wastewater, such as municipal sewage, industrial wastewater and domestic sewage, and is of great significance for improving environmental quality.

[0003] However, existing deodorizing wastewater treatment devices have two prominent drawbacks in actual use, severely affecting their treatment efficiency and purification rate. First, when adding the treatment agent, it is usually poured directly into the working shell through the inlet. Because the agent cannot immediately and evenly distribute with the wastewater upon pouring, the treatment effect is significantly uneven, thus reducing the overall treatment efficiency. Second, most purification devices use a stirring rod to mix the treatment agent with the wastewater, but conventional stirring rods rotate in one direction. This method results in a slow mixing speed and insufficient uniformity, further affecting the purification rate and failing to meet the actual requirements for efficient wastewater treatment. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an odor-removing environmental wastewater purification and treatment device to solve the problems mentioned in the background technology.

[0005] According to one aspect of this application, an odor-deodorizing environmental wastewater purification and treatment device includes a treatment cylinder, a support frame, an aeration mechanism, a stirring mechanism, and a dosing mechanism. The bottom of the treatment cylinder is fixedly connected to the support frame, which is located on the ground. An aeration mechanism is provided on the inner wall of the treatment cylinder, and the aeration mechanism is connected to an air pump via a vent pipe. The air pump is located on the ground. A stirring mechanism is provided at the axial position inside the treatment cylinder. Both the stirring mechanism and the aeration mechanism are vertically arranged along the axial direction of the treatment cylinder, and the aeration mechanism is distributed circumferentially on the inner wall of the treatment cylinder. The stirring mechanism is located at the axial position inside the treatment cylinder. An annular space is left between the stirring mechanism and the aeration mechanism to form an aeration channel. A dosing mechanism is provided at the top of the treatment cylinder, and the dosing mechanism is positioned directly opposite the aeration channel. An inlet pipe is connected to the top outer wall of the treatment cylinder, and an outlet pipe is connected to the bottom outer wall of the treatment cylinder. A shut-off valve is fixedly installed at the connection position between the outlet pipe and the treatment cylinder.

[0006] Preferably, the aeration mechanism includes an air supply pipe, an annular connecting pipe, and aerators. The air supply pipe is vertically fixed on the inner wall of the treatment cylinder along its axial direction. The top of the air supply pipe is connected to the ventilation pipe through an interface. Several horizontally arranged annular connecting pipes are equidistantly distributed along the axial direction of the air supply pipe. Each annular connecting pipe is circumferentially arranged along the inner wall of the treatment cylinder and is fixedly connected to the inner wall of the treatment cylinder by a fastener. Several aerators are equidistantly connected along the direction of each annular connecting pipe, and each aerator is oriented towards the inner axis of the treatment cylinder.

[0007] Preferably, the agitation mechanism includes a motor, a rotating shaft, and helical blades. The motor is fixedly installed on the bottom outer side of the processing cylinder. The output shaft of the motor is fixedly connected to the lower end of the rotating shaft. The rotating shaft is vertically arranged along the internal axis of the processing cylinder, and the upper and lower ends of the rotating shaft are respectively rotatably located on the upper and lower surfaces inside the processing cylinder. Helical blades are fixedly provided on the outer circumference of the rotating shaft along its axial direction, and the helical blades extend into the upper and lower parts inside the processing cylinder.

[0008] Preferably, the annular space between the outer periphery of the spiral blade and the plurality of annular connecting pipes is the aeration channel.

[0009] Preferably, the dosing mechanism includes a storage tank, a pump, a delivery pipe, an annular dosing pipe, and dosing nozzles. The storage tank is located on the ground, and the pump is installed on the storage tank. The inlet of the pump is connected to the storage tank, and the outlet of the pump is connected to one end of the delivery pipe. The other end of the delivery pipe is connected to the annular dosing pipe. The annular dosing pipe is located at the top of the treatment cylinder, and several dosing nozzles are equidistantly arranged along its direction. Each dosing nozzle penetrates downward through the top of the treatment cylinder and faces the aeration channel.

[0010] Preferably, the inlet of the sewage inlet pipe and the outlet of the sewage outlet pipe are provided with connecting flanges for connecting external equipment.

[0011] The advantages of this application compared to existing technologies are as follows: This application provides an odor-removing environmental wastewater purification device. By setting a dosing mechanism corresponding to an aeration channel, the dosing mechanism's spray nozzle can evenly spray the treatment agent into the aeration channel, replacing the traditional direct pouring dosing method. This allows the treatment agent to initially diffuse within the aeration channel. Combined with the bubble agitation generated by the aeration mechanism, this effectively avoids the problem of localized agent aggregation, ensuring uniform contact between the treatment agent and wastewater, improving the uniformity of the treatment effect, and thus increasing the device's treatment efficiency. Furthermore, the agitation mechanism of this invention uses spiral blades extending axially along the rotating shaft. When the motor drives the rotating shaft, the spiral blades can cause the wastewater to circulate vertically and in a circular motion, breaking with traditional methods. The limitation of a unidirectional stirring rod, which can only drive the sewage to flow in one direction, accelerates the mixing speed of the treatment agent and sewage. At the same time, the fine bubbles sprayed by the aeration mechanism further increase the contact area between the treatment agent and sewage, improve the mixing uniformity, and effectively improve the purification rate of the sewage. The aeration mechanism of this invention adopts multiple sets of annular connecting pipes equidistantly distributed along the axial direction of the treatment cylinder. Each annular connecting pipe is equipped with an aerator facing the center of the treatment cylinder, so that the aeration bubbles can be evenly distributed along the circumference and axial direction of the treatment cylinder. This not only accelerates the mixing of the treatment agent and sewage, but also fully removes odor substances contained in the sewage, improving the deodorization effect of the device. At the same time, the dissolved oxygen content in the sewage is increased during the aeration process, which facilitates the subsequent oxidation reaction and further improves the sewage purification effect.

[0019] To make the content of this application easier to understand, the appendices in the embodiments of this application will be described below. Figure 1-6 The technical solutions in the embodiments of this application will be clearly and completely described. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the appendix. Figure 2 In the context of direction, the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figures 1-6 As shown, an odor-deodorizing environmental wastewater purification and treatment device includes a treatment cylinder 1, a support frame 2, an aeration mechanism 3, a stirring mechanism 4, and a dosing mechanism 5. The bottom of the treatment cylinder 1 is fixedly connected to the support frame 2, which is set on the ground to provide stable support for the entire device and ensure that the device will not shake or tip over during operation. The support frame 2 can be made of stainless steel, and its height can be adapted to the actual size of the treatment cylinder 1 and the application scenario.

[0021] An aeration mechanism 3 is installed on the inner wall of the treatment cylinder 1. The aeration mechanism 3 is connected to an air pump 7 via a vent pipe 6. The air pump 7 is located on the ground. When the air pump 7 is working, it can deliver high-pressure gas into the aeration mechanism 3. The air pump 7 can be a Roots blower, and its rated air volume and pressure can be selected according to the volume of the treatment cylinder 1 and the sewage treatment capacity. An agitation mechanism 4 is installed at the axial position inside the treatment cylinder 1. Both the agitation mechanism 4 and the aeration mechanism 3 are vertically arranged along the axial direction of the treatment cylinder 1. The aeration mechanism 3 is distributed around the inner wall of the treatment cylinder 1, and the agitation mechanism 4 is located at the axial position inside the treatment cylinder 1. An annular space is left between the agitation mechanism 4 and the aeration mechanism 3 to form an aeration channel. The aeration channel allows the bubbles generated by the aeration mechanism 3 to diffuse evenly along the annular area, while providing buffering and initial diffusion space for the treatment agent added by the dosing mechanism 5.

[0022] A dosing mechanism 5 is installed at the top of the treatment cylinder 1, which is directly opposite the aeration channel to ensure that the treatment agent can fall accurately into the aeration channel and fully contact the aeration bubbles and sewage. An inlet pipe 8 is connected to the top outer wall of the treatment cylinder 1, through which the sewage to be treated enters the treatment cylinder 1. An outlet pipe 9 is connected to the bottom outer wall of the treatment cylinder 1, through which the treated sewage that meets the standards is discharged. A shut-off valve 10 is fixedly installed at the connection between the outlet pipe 9 and the treatment cylinder 1. The shut-off valve 10 can control the opening and closing of the outlet pipe 9, which allows the staff to control the timing of drainage according to the sewage treatment progress. The shut-off valve 10 can be a ball valve or a gate valve to ensure good sealing performance and prevent sewage leakage.

[0023] The aeration mechanism 3 includes an air supply pipe 301, an annular connecting pipe 302, and an aerator 303. The air supply pipe 301 is vertically fixed to the inner wall of the treatment cylinder 1 along its axial direction. The air supply pipe 301 can be fixedly connected to the inner wall of the treatment cylinder 1 by welding to ensure a firm connection. The top of the air supply pipe 301 is connected to the air pipe 6 through an interface, and a sealing gasket can be installed at the interface to prevent gas leakage. Several horizontally arranged annular connecting pipes 302 are evenly distributed along the axial direction of the air supply pipe 301. The number of annular connecting pipes 302 can be set according to the height of the treatment cylinder 1. Each annular connecting pipe 302 is arranged circumferentially along the inner wall of the treatment cylinder 1 and is fixedly connected to the inner wall of the treatment cylinder 1 by a fastener 304. The fastener 304 can be bolted or welded to ensure that the annular connecting pipe 302 will not shift during operation. Each annular connecting pipe 302 is equidistantly connected with several aerators 303 along its direction. The number of aerators 303 can be adapted according to the circumference of the annular connecting pipe 302, and each aerator 303 is set towards the inner axis of the treatment cylinder 1, so that the bubbles sprayed by the aerator 303 can diffuse towards the central area of ​​the treatment cylinder 1 and fully mix with the sewage agitated by the stirring mechanism 4, thereby improving the aeration effect and deodorization and purification efficiency. The aerators 303 can be microporous aerators, and their pore size can be controlled between 10 and 20 micrometers to ensure that the generated bubbles are small and uniform, thereby increasing the contact area between the gas and the sewage.

[0024] The agitation mechanism 4 includes a motor 401, a rotating shaft 402, and a spiral blade 403. The motor 401 is fixedly installed on the bottom outer side of the processing cylinder 1. The motor 401 can be fixed to a mounting base at the bottom of the processing cylinder 1 by bolts. The mounting base is welded to the bottom of the processing cylinder 1. The output shaft of the motor 401 is fixedly connected to the lower end of the rotating shaft 402. The connection method can be a coupling to ensure stable power transmission. The rotating shaft 402 is vertically arranged along the internal axis of the processing cylinder 1, and the upper and lower ends of the rotating shaft 402 are respectively rotatably located on the upper and lower surfaces inside the processing cylinder 1. Bearing seats can be installed on the upper and lower surfaces inside the processing cylinder 1. The two ends of the rotating shaft 402 are rotatably connected to the bearing seats through bearings, which reduces the friction during the rotation of the rotating shaft 402 and extends the service life of the rotating shaft 402. A spiral blade 403 is fixedly provided on the outer periphery of the rotating shaft 402 along its axial direction. The spiral blade 403 can be fixedly connected to the rotating shaft 402 by welding. The spiral blade 403 extends into the upper and lower parts of the treatment cylinder 1 to ensure that the sewage in the upper and lower areas of the treatment cylinder 1 can be effectively agitated. When the motor 401 drives the rotating shaft 402 to rotate, the spiral blade 403 rotates accordingly, which can drive the sewage to circulate up and down and move in a circular motion, breaking the limitation of unidirectional stirring and accelerating the mixing speed of the treatment agent and sewage.

[0025] The annular space between the outer periphery of the spiral blade 403 and several annular connecting pipes 302 is an aeration channel. The width of the aeration channel can be designed according to the inner diameter of the treatment cylinder 1, the outer diameter of the spiral blade 403 and the installation position of the annular connecting pipes 302. It is usually controlled at 5 to 10 cm to ensure that the aeration bubbles can flow smoothly and facilitate the full diffusion of the treatment agent in the channel.

[0026] The dosing mechanism 5 includes a storage tank 501, a pump 502, a delivery pipe 503, an annular dosing pipe 504, and a liquid spray nozzle 505. The storage tank 501 is located on the ground and is used to store the treatment agent. The storage tank 501 can be made of corrosion-resistant material to prevent the treatment agent from corroding the tank body. The pump 502 is installed on the storage tank 501 and can be fixed to the top of the storage tank 501. The inlet of the pump 502 is connected to the storage tank 501. A filter can be installed at the inlet to prevent impurities in the treatment agent from entering the pump 502 and damaging the pump body. The outlet of the pump 502 is connected to one end of the delivery pipe 503, and the other end of the delivery pipe 503 is connected to the annular dosing pipe 504. The delivery pipe 503 can be made of corrosion-resistant rubber or steel. The annular dosing pipe 504 is located at the top of the treatment cylinder 1 and can be fixedly connected to the top of the treatment cylinder 1 by a bracket to ensure stable installation. Several liquid spray nozzles 505 are equidistantly connected along the direction of the annular dosing pipe 504. The number of liquid spray nozzles 505 is matched with the number of aerators 303 on the annular connecting pipe 302. Each liquid spray nozzle 505 is directed downward through the top of the treatment cylinder 1 and towards the aeration channel, so that the treatment agent can be evenly sprayed into the aeration channel through the liquid spray nozzle 505. After spraying, the treatment agent can be quickly and evenly mixed with the sewage under the disturbance of the aeration bubbles and the stirring action of the stirring mechanism 4, avoiding the problem of uneven treatment caused by local aggregation of treatment agent.

[0027] The inlet of the sewage inlet pipe 8 and the outlet of the sewage outlet pipe 9 are equipped with connecting flanges for connecting external equipment. The connecting flanges can be integrally formed with the sewage inlet pipe 8 and the sewage outlet pipe 9 or welded and fixed. The connecting flanges are provided with several connecting holes, which facilitates the fixed connection with the external sewage conveying pipeline by bolts, ensuring a tight connection and preventing sewage leakage. At the same time, it is convenient for the installation, disassembly and maintenance of the device.

[0028] The working process of this embodiment is as follows: In use, first connect the device to the external sewage conveying pipeline through the connecting flange of the inlet pipe 8, and connect the device to the treated sewage conveying pipeline through the connecting flange of the outlet pipe 9. Close the shut-off valve 10. Add an appropriate amount of sewage treatment agent into the storage tank 501 and tighten the cover. Start the air pump 7 and motor 401. When the air pump 7 is working, it delivers high-pressure gas to the air supply pipe 301 through the air pipe 6. The gas enters each annular connecting pipe 302 through the air supply pipe 301, and then sprays fine bubbles into the treatment cylinder 1 through the aerator 303 on the annular connecting pipe 302. The bubbles diffuse towards the center of the treatment cylinder 1 along the aeration channel. When the motor 401 is working, it drives the rotating shaft 402 to rotate, which in turn drives the spiral blades 403 to rotate. The spiral blades 403 cause the sewage inside the treatment cylinder 1 to circulate up and down and move in a circular motion.

[0029] Then, the pump 502 is started, drawing out the treatment agent from the storage tank 501 and delivering it through the delivery pipe 503 to the annular dosing pipe 504. The agent is then evenly sprayed into the aeration channel through the spray nozzles 505 on the annular dosing pipe 504. The sprayed treatment agent initially diffuses under the agitation of the aeration bubbles, and then, under the stirring action of the spiral blades 403, quickly and evenly mixes with the wastewater inside the treatment cylinder 1. The treatment agent undergoes chemical reaction and physical adsorption with the wastewater, removing harmful and odorous substances.

[0030] During the wastewater treatment process, staff can observe the wastewater's condition based on the treatment progress. Once the wastewater meets the treatment standards, the shut-off valve 10 is opened, and the treated wastewater is discharged through the outlet pipe 9 into the subsequent conveying pipeline. Throughout the entire process, the aeration mechanism 3 continuously aerates the wastewater, which not only assists in mixing the treatment agent with the wastewater but also removes odorous substances from the wastewater, achieving deodorization. The stirring mechanism 4 continuously stirs the wastewater, ensuring uniform and stable treatment results and effectively improving the device's treatment efficiency and purification rate.

[0031] The above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them. Although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, without departing from the spirit and scope defined by the claims of this application.
