Description

Technical Field

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

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering.

[0003] Wastewater treatment can be categorized into three types based on its function: physical, biological, and chemical methods. Chemical methods utilize chemical reactions to treat or recover dissolved or colloidal substances in wastewater. Commonly used chemical methods include coagulation, neutralization, oxidation-reduction, and ion exchange. Chemical methods typically involve adding wastewater treatment agents to the wastewater. These agents react with pollutants in the wastewater, purifying it. The probability and amount of contact between the wastewater treatment agent and the pollutants directly affect the purification effect. Therefore, a low probability and low amount of contact between the wastewater treatment agent and the pollutants will result in low agent utilization and ultimately poor wastewater purification.

[0004] Therefore, it is necessary to provide a wastewater treatment device that increases the contact probability between wastewater treatment agents and pollutants in wastewater, thereby increasing the contact amount between wastewater treatment agents and pollutants in wastewater, and thus improving the utilization rate of wastewater treatment agents and the purification effect of wastewater treatment agents on wastewater. Utility Model Content

[0005] To overcome the problems in the prior art, this utility model sets a conical disc between the sewage inlet and the spraying mechanism. When sewage enters the reaction tank from the sewage inlet, it falls onto the conical disc. Due to the obstruction of the conical disc, the sewage disperses in all directions and continues to fall. At this time, after the spraying mechanism sprays the sewage treatment agent, the sewage is in a dispersed state, and the pollutants in the sewage are also in a dispersed state. The probability and amount of contact between the sewage treatment agent and the pollutants in the dispersed sewage are increased, thereby improving the utilization rate of the sewage treatment agent and enhancing the purification effect of the sewage treatment agent on the sewage.

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

[0007] The wastewater treatment device includes a reaction tank 1, a tank cover 2 on the top of the reaction tank 1, a wastewater inlet 3 on the tank cover 2, the wastewater inlet 3 being connected to a wastewater source via a wastewater inlet pipe 4, a spraying mechanism 5 installed on the inner side wall of the reaction tank 1, the spraying mechanism 5 being connected to a wastewater treatment agent source via a pipe, a conical disc 6 installed inside the reaction tank 1, the conical disc 6 being located in the space between the wastewater inlet 3 and the spraying mechanism 5, and the center point of the conical disc 6 being on the same vertical line as the center point of the wastewater inlet 3, with the tip of the conical disc 6 facing the wastewater inlet 3, and a water outlet being opened at the bottom of the side wall of the reaction tank 1, with a valve 7 installed at the water outlet.

[0008] Preferably, the conical disc 6 is fixedly mounted on the bottom surface of the bucket lid 2 via a connecting rod 8.

[0009] Preferably, a nozzle 9 is installed on the side wall of the sewage inlet pipe 4, and the nozzle 9 is connected to the sewage treatment agent source through a pipe.

[0010] Preferably, a motor 10 is fixedly installed on the top surface of the bucket cover 2, and the output end of the motor 10 is connected to the stirring paddle 11 through a coupling.

[0011] Preferably, the bottom end of the stirring paddle 11 is fixedly connected to the scraper 12, and the bottom surface of the scraper 12 is in contact with the bottom surface of the inner side of the reaction tank 1.

[0012] Preferably, the spraying mechanism 5 includes an atomizing nozzle 501 and a nozzle pipe 502. The nozzle pipe 502 is fixedly installed on the inner side wall of the reaction tank 1. The atomizing nozzle 501 is installed on the nozzle pipe 502 and communicates with the nozzle pipe 502. The nozzle pipe 502 is communicated with the sewage treatment agent source.

[0013] Preferably, the nozzle pipe 502 is an annular pipe, and there are at least two atomizing nozzles 501, which are evenly arranged along the nozzle pipe 502.

[0014] Preferably, the wastewater treatment device further includes an electric push rod 13, of which there are at least two, which are evenly arranged around the circumference of the reaction tank 1. The base of the electric push rod 13 is fixedly installed on the outer wall of the reaction tank 1, and the end of the telescopic section of the electric push rod 13 is connected to the tank cover 2.

[0015] Preferably, the wastewater treatment device further includes a storage tank 14 for storing wastewater treatment agents. A dosing port 15 is provided on the top surface of the storage tank 14, and an infusion pump 16 is installed on the top surface of the storage tank 14. The inlet end of the infusion pump 16 is connected to the wastewater treatment agents stored in the storage tank 14 through a pipe, and the outlet end of the infusion pump 16 is connected to the spraying mechanism 5 and the nozzle 9 through branch pipes respectively.

[0016] Preferably, a glass window 17 is provided on the side wall of the reaction vessel 1.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model, by setting a conical disc, allows wastewater to fall onto the conical disc first after entering the reaction tank. Through the blocking effect of the conical disc, the wastewater changes from a stream to a dispersed state. The wastewater treatment agent sprayed by the spraying mechanism has a larger contact area with the dispersed wastewater, making it easier for the wastewater treatment agent to come into contact with pollutants in the wastewater. This increases the contact amount between the wastewater treatment agent and pollutants, ultimately improving the utilization rate of the wastewater treatment agent and enhancing its purification effect on wastewater.

[0019] 2. This utility model uses a stirring paddle to agitate the dispersed wastewater in the reaction tank and the wastewater treatment agent sprayed by the spraying mechanism, causing the dispersed wastewater and wastewater treatment agent to move in the reaction tank, thereby further increasing the probability of contact between the wastewater treatment agent and pollutants in the wastewater.

[0020] 3. By setting up a scraper, this utility model can scrape up the material deposited on the bottom surface of the reaction tank during the stirring process of the agitator, thus avoiding excessive material accumulation and increasing the difficulty of cleaning the reaction tank.

[0021] 4. This invention installs nozzles on the side wall of the sewage inlet pipe. After the nozzles spray sewage treatment agents, they can mix with the sewage flowing in the sewage inlet pipe, so that the sewage can be pre-treated, reducing the pollutant content of the sewage after it enters the reaction tank, and reducing the difficulty of sewage treatment in the reaction tank.

Detailed Implementation

[0027] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0028] like Figure 1-4 As shown, the wastewater treatment device includes a reaction tank 1, a tank cover 2 on the top of the reaction tank 1, a wastewater inlet 3 on the tank cover 2, the wastewater inlet 3 being connected to a wastewater source via a wastewater inlet pipe 4, a spraying mechanism 5 installed on the inner side wall of the reaction tank 1, the spraying mechanism 5 being connected to a wastewater treatment agent source via a pipe, a conical disc 6 installed inside the reaction tank 1, the conical disc 6 being located in the space between the wastewater inlet 3 and the spraying mechanism 5, and the center point of the conical disc 6 being on the same vertical line as the center point of the wastewater inlet 3, with the tip of the conical disc 6 facing the wastewater inlet 3, and a water outlet being opened at the bottom of the side wall of the reaction tank 1, with a valve 7 installed at the water outlet.

[0029] During wastewater treatment, the lid 2 is closed to the reaction tank 1. Wastewater flows through the wastewater inlet pipe 4 and enters the reaction tank 1 through the wastewater inlet 3. After entering the reaction tank 1, the wastewater falls to the conical disc 6 under gravity. When the wastewater flows into the reaction tank 1 from the wastewater inlet 3, it forms a stream. When the wastewater hits the conical disc 6, it is blocked by the conical disc 6 and becomes dispersed, continuing to fall. The spraying mechanism 5 located below the conical disc 6 sprays wastewater treatment agents. The wastewater treatment agents come into contact more easily with the dispersed wastewater, resulting in a larger contact area. This allows more wastewater treatment agents to easily contact the wastewater and react chemically with the pollutants in the wastewater, effectively improving the utilization rate of the wastewater treatment agents and ultimately enhancing the treatment effect of the wastewater. The treated wastewater is transformed into cleaner water and falls to the bottom of the reaction tank 1. Opening the valve 7 allows the cleaner water at the bottom of the reaction tank 1 to be discharged and collected for later use.

[0030] The conical disc 6 is fixedly installed on the bottom surface of the bucket lid 2 via a connecting rod 8.

[0031] When the wastewater treatment device is working, the lid 2 is closed to the reaction tank 1, allowing the conical disk 6 to work normally inside the reaction tank 1. When the wastewater treatment device is not working, opening the lid 2 allows the conical disk 6 to move together with the lid 2 and be removed from the reaction tank 1. This avoids the conical disk 6 obstructing the operation during cleaning or other operations inside the reaction tank 1.

[0032] Sprayer 9 is installed on the side wall of the sewage inlet pipe 4, and the sprayer 9 is connected to the sewage treatment agent source through a pipe.

[0033] When the sewage flows in the sewage inlet pipe 4, the nozzle 9 sprays out sewage treatment agent. The sprayed sewage treatment agent mixes and comes into contact with the sewage in the sewage inlet pipe 4, performing preliminary treatment on the sewage to reduce the pollutant content in the sewage to a certain extent, thereby reducing the difficulty of treating the sewage after it enters the reaction tank 1.

[0034] A motor 10 is fixedly installed on the top surface of the bucket cover 2, and the output end of the motor 10 is connected to the stirring paddle 11 through a coupling.

[0035] During the wastewater treatment process, the motor 10 is turned on, and the motor 10 drives the agitator 11 to rotate. The agitator 11 stirs the dispersed wastewater and wastewater treatment agents in the reaction tank 1, causing the wastewater and wastewater treatment agents to move within the reaction tank 1, thereby further increasing the contact amount between the wastewater treatment agents and the wastewater, which helps to improve the wastewater treatment effect.

[0036] The bottom end of the stirring paddle 11 is fixedly connected to the scraper 12, and the bottom surface of the scraper 12 is in contact with the bottom surface of the inner side of the reaction tank 1.

[0037] Since the treated wastewater or a small amount of unreacted wastewater treatment agent will eventually fall to the bottom of the reaction tank 1, as the reaction tank 1 is used for a longer period of time, sediment may be generated at the bottom of the reaction tank 1. If it is not treated, excessive sediment accumulation will affect the wastewater treatment work and increase the difficulty of cleaning the inside of the reaction tank 1. Therefore, when the stirring paddle 11 rotates and stirs, it drives the scraper 12 to rotate, scraping up the sediment deposited on the bottom surface of the reaction tank 1, so that the sediment can be discharged from the reaction tank 1, avoiding sediment accumulation, reducing the impact of sediment on the wastewater treatment work, and at the same time reducing the workload and difficulty of cleaning the inside of the reaction tank 1.

[0038] The spraying mechanism 5 includes an atomizing nozzle 501 and a nozzle pipe 502. The nozzle pipe 502 is fixedly installed on the inner side wall of the reaction tank 1. The atomizing nozzle 501 is installed on the nozzle pipe 502 and communicates with the nozzle pipe 502. The nozzle pipe 502 is communicated with the sewage treatment agent source.

[0039] Wastewater treatment agent is transported to the nozzle pipe 502 through a pipeline and flows in the nozzle pipe 502. The wastewater treatment agent in the nozzle pipe 502 is sprayed out in the form of atomization through the atomizing nozzle 501, so that more places in the reaction tank 1 have wastewater treatment agent, and the dispersed wastewater is more likely to come into contact with the wastewater treatment agent, which is conducive to improving the wastewater treatment effect.

[0040] The nozzle pipe 502 is an annular pipe, and there are at least two atomizing nozzles 501, which are evenly arranged along the nozzle pipe 502. This allows the wastewater treatment agent to be sprayed from more locations, and the spraying position is more uniform, resulting in a more even distribution of the wastewater treatment agent within the reaction tank 1.

[0041] The wastewater treatment device also includes electric push rods 13, at least two of which are evenly arranged around the circumference of the reaction tank 1. The base of the electric push rod 13 is fixedly installed on the outer wall of the reaction tank 1, and the end of the telescopic section of the electric push rod 13 is connected to the tank cover 2.

[0042] Because the lid 2 is equipped with components such as the motor 10, and due to its own weight, the lid 2 may be quite heavy, making it difficult to open and close manually. Therefore, by extending the electric push rod 13, the lid 2 can be lifted, thus opening the lid 2. By shortening the electric push rod 13, the lid 2 can be placed back onto the reaction vessel 1, thus closing the lid. The telescopic end of the electric push rod 13 can be fixedly connected to the lid 2 or detachably connected. In the detachable connection method, a groove can be cut into the lid 2, with the groove located at the contact point between the lid 2 and the electric push rod 13. When the electric push rod 13 extends, its telescopic end can extend into the groove and lift the lid 2. Alternatively, the telescopic end of the electric push rod 13 can directly lift the lid 2, with the lid 2 pressing down on the telescopic end of the electric push rod 13 with its own weight to maintain stability during the extension of the electric push rod 13.

[0043] The wastewater treatment device also includes a storage tank 14, which stores wastewater treatment agents. A dosing port 15 is opened on the top surface of the storage tank 14, and an infusion pump 16 is installed on the top surface of the storage tank 14. The inlet end of the infusion pump 16 is connected to the wastewater treatment agents stored in the storage tank 14 through a pipe, and the outlet end of the infusion pump 16 is connected to the spraying mechanism 5 and the nozzle 9 through branch pipes respectively.

[0044] The wastewater treatment agent stored in the storage tank 14 serves as the wastewater treatment agent source. The agent is extracted from the storage tank 14 by the infusion pump 16 and pumped through branch pipes to the spraying mechanism 5 and the nozzle 9, enabling them to spray the wastewater treatment agent. Simultaneously, wastewater treatment agent can be replenished into the storage tank 14 through the dosing port 15.

[0045] A glass window 17 is provided on the side wall of the reaction tank 1. This allows staff to observe the interior of the reaction tank 1 through the glass window 17 to monitor the wastewater treatment process.

[0046] The working process of this utility model is as follows: When sewage treatment is required, the infusion pump and motor are first turned on. The motor drives the agitator to rotate. The infusion pump pumps the sewage treatment agent in the storage tank to the spraying mechanism and nozzles. The nozzles spray the sewage treatment agent into the sewage inlet pipe. The spraying mechanism sprays the sewage treatment agent into the reaction tank. At the same time, sewage is supplied to the reaction tank from the sewage source. The sewage enters the reaction tank through the sewage inlet pipe. The sewage treatment agent sprayed from the nozzles mixes with the sewage in the sewage inlet pipe and undergoes a chemical reaction, performing preliminary purification treatment on the sewage. After entering the reaction tank, the sewage falls to the conical plate, changing from a stream of water flow to... The water flows in a dispersed stream and continues to descend, coming into contact with the mist-like wastewater treatment agent sprayed by the spraying mechanism to produce a chemical reaction. The treated wastewater then falls to the bottom of the reaction tank. After a certain amount of water accumulates at the bottom, it can be drained through a valve for unified collection, thus completing the wastewater treatment process. During the treatment process, the agitator stirs the wastewater and wastewater treatment agent within the reaction tank, while a scraper lifts up the sediment deposited at the bottom of the tank, draining it along with the water for collection and subsequent treatment. The tank lid remains closed, and personnel can observe the wastewater treatment process through an observation window. If cleaning or other work is required, an electric actuator is activated, extending and lifting the tank lid to open it for cleaning.

[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
