Description

Technical Field

[0001] This utility model relates to the field of acid and alkali wastewater treatment technology, specifically a wastewater treatment device based on acid and alkali adjustment. Background Technology

[0002] In the field of industrial processing, certain acidic and alkaline wastewater is usually generated. Acidic liquid is a waste liquid with a pH value of less than 6, while alkaline liquid is a waste liquid with a pH value of greater than 9. Because the pH values ​​of these two liquids are too high or too low, they will change the pH value of the liquid and soil when they enter the natural environment, thus causing a huge impact on the natural environment.

[0003] Chinese Patent CN202211310415.X relates to the field of industrial wastewater treatment equipment technology and discloses an environmentally friendly industrial wastewater mixing and treatment device based on acid-base adjustment. The device includes a neutralization tank, with support columns fixedly connected to the front and rear ends of both sides of the bottom. An inlet pipe is fixedly connected to the center of the top of the neutralization tank. The use of a condenser cools and condenses the liquid passing through it, ensuring that the liquid entering the separator is a coolant. Three hollow rotating rods allow the liquid entering the separator to enter the rotating rods. This allows the rotating rods and stirring blades to cool the heat generated during the neutralization process of the acid and base liquids in the first, second, and third treatment chambers, preventing overheating of the neutralization tank surface and thus preventing burns to the acid-base detector, temperature detector, and personnel outside the equipment.

[0004] Most existing methods for treating acidic and alkaline wastewater involve directly adding chemicals into the wastewater and then reacting them with the wastewater through stirring. However, in actual use, the addition of chemicals may result in problems such as excessively high local concentrations of chemicals or insufficient local concentrations of chemicals, preventing the wastewater from fully reacting.

[0005] Therefore, a wastewater treatment device based on acid-base adjustment is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this paper addresses the problem that most existing methods for treating acidic and alkaline wastewater involve directly adding chemicals into the wastewater and then reacting with the wastewater through stirring. However, in actual use, the addition of chemicals may result in either excessively high local concentrations or insufficient local concentrations, preventing the wastewater from fully reacting.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The wastewater treatment device based on acid-base adjustment of this utility model includes a neutralizing agent treatment component, a filter component installed on the side of the neutralizing agent treatment component, and a multi-stage reaction tank component installed at the bottom of the filter component; the neutralizing agent treatment component includes a water tank, a hinge is fixedly connected to one side of the water tank, and a cover plate is fixedly connected to the other side of the hinge; a first motor is fixedly connected to the top of the water tank, and a first threaded rod is fixedly connected to the end of the first motor, and a second threaded rod is engaged with the end of the first threaded rod; a nut is threadedly connected to the outer wall of the second threaded rod, and a stirring rod is provided at the bottom of the nut, and a solenoid valve is provided on the side of the stirring rod.

[0008] Preferably, the cover plate forms a rotating structure with the water tank via a hinge, and the water tank forms a communicating structure with the solenoid valve.

[0009] Preferably, the first motor forms a transmission structure with the stirring rod through the first threaded rod, the nut, and the second threaded rod, and the first threaded rod and the second threaded rod form an engaging structure, and both the first threaded rod and the second threaded rod form a threaded detachable structure with the nut.

[0010] Preferably, the filter assembly includes a housing, the inside of which is provided with a groove, and a slider is slidably connected inside the groove. A larger filter screen is fixedly connected to the side of the slider, and a smaller filter screen is provided at the bottom of the larger filter screen.

[0011] Preferably, the larger filter screen is formed by a slider, a groove and a housing to form a sliding structure, and the slider and the larger filter screen are integrated.

[0012] Preferably, the multi-stage reaction tank assembly includes a mounting shell, inside which a second motor is installed, and a transmission rod is fixedly connected to the top of the second motor. A stirring blade is fixedly connected to the outer wall of the transmission rod. A reaction tank body is provided on the side of the stirring blade, and a pH sensor is fixedly connected inside the reaction tank body. A ball valve is provided on the side of the pH sensor, and an outlet pipe is provided at the end of the ball valve.

[0013] Preferably, the second motor forms a transmission structure with the stirring blades via a transmission rod, and the stirring blades are arranged at equal intervals with respect to the outer wall of the transmission rod. The reaction tank body forms a communication structure with the ball valve, and the reaction tank body forms a communication structure with the water outlet pipe.

[0014] The advantages of this utility model are:

[0015] 1. This utility model incorporates a neutralizing drug treatment component. A water tank allows for the pre-dissolution and proportioning of the required drugs before they are added to the wastewater. This prevents drug accumulation and incomplete reactions during the reaction process. Furthermore, the bolted threaded rod and stirring rod facilitate disassembly, cleaning, and installation, effectively preventing excessively high local drug concentrations that could lead to incomplete drug reactions.

[0016] 2. This utility model incorporates a filtration system. First, a primary coarse filter is used to remove large particles, such as suspended solids and silt, from the wastewater. Then, a secondary filter, using activated carbon or fiber filter media, further removes smaller particles and organic matter, reducing the turbidity of the wastewater. This dual filtration method effectively reduces the impact of larger impurities in the wastewater on subsequent reactions.

[0017] 3. This utility model incorporates a multi-stage reaction tank assembly, with different levels that can be optimized for specific treatment objectives. For example, the first stage can quickly neutralize strong acids and alkalis in the wastewater, rapidly bringing the pH value closer to the target range; subsequent stages can precisely adjust residual trace amounts of acid and alkali, ensuring the wastewater's pH meets strict discharge standards. As the wastewater flows through different stages sequentially, the reaction time with the treatment agents is extended, increasing the opportunity for sufficient contact between the wastewater and treatment agents such as acid-base regulators and flocculants, thereby improving the completion rate of various reactions and resulting in a more significant treatment effect.

[0028] Please see Figure 1 and Figure 5 The wastewater treatment device based on acid-base adjustment is shown, including a neutralizing agent treatment component 1, a filter component 2 installed on the side of the neutralizing agent treatment component 1, and a multi-stage reaction tank component 3 installed at the bottom of the filter component 2; the neutralizing agent treatment component 1 includes a water tank 101, a hinge 102 fixedly connected to one side of the water tank 101, and a cover plate 103 fixedly connected to the other side of the hinge 102; a first motor 104 fixedly connected to the top of the water tank 101, and a first threaded rod 105 fixedly connected to the end of the first motor 104; a second threaded rod 108 engaged with the end of the first threaded rod 105; a nut 106 threadedly connected to the outer wall of the second threaded rod 108; a stirring rod 109 provided at the bottom of the nut 106; and a solenoid valve 107 provided on the side of the stirring rod 109.

[0029] like Figure 3The cover plate 103 shown is connected to the water tank 101 via a hinge 102 to form a rotating structure, and the water tank 101 is connected to the solenoid valve 107. The first motor 104 is connected to the stirring rod 109 via a first threaded rod 105, a nut 106, a second threaded rod 108 to form a transmission structure, and the first threaded rod 105 and the second threaded rod 108 form a locking structure. Both the first threaded rod 105 and the second threaded rod 108 are connected to the nut 106 to form a threaded detachable structure. The threaded rod and stirring rod 109 with bolt connections can be more easily disassembled, cleaned and installed.

[0030] Please see Figure 4 The wastewater treatment device based on acid-base adjustment is shown. The filter assembly 2 includes a housing 201. A groove 202 is opened inside the housing 201, and a slider 203 is slidably connected inside the groove 202. A larger filter screen 204 is fixedly connected to the side of the slider 203, and a smaller filter screen 205 is set at the bottom of the larger filter screen 204. First, a primary coarse filter screen is set to remove large particulate matter, such as suspended solids and silt, from the wastewater. Then, the wastewater passes through a secondary filter screen, which uses activated carbon or fiber filter media to further remove smaller particles and organic matter, thereby reducing the turbidity of the wastewater. The dual filtration method can effectively reduce the occurrence of larger impurities in the wastewater and their impact on subsequent reactions.

[0031] like Figure 4 The larger filter screen 204 is connected to the outer shell 201 via a slider 203, a groove 202 to form a sliding structure. The slider 203 and the larger filter screen 204 are integrated, which makes it easier to clean and replace the filter screen.

[0032] Please see Figure 5 The diagram illustrates a wastewater treatment device based on acid-base adjustment. The multi-stage reaction tank assembly 3 includes a mounting shell 301. A second motor 302 is installed inside the mounting shell 301, and a transmission rod 303 is fixedly connected to the top of the second motor 302. A stirring plate 304 is fixedly connected to the outer wall of the transmission rod 303. A reaction tank body 305 is located on the side of the stirring plate 304, and a pH sensor 308 is fixedly connected inside the reaction tank body 305. A ball valve 306 is located on the side of the pH sensor 308, and an outlet pipe 307 is located at the end of the ball valve 306. By setting different stages, the device can be optimized for specific treatment objectives.

[0033] like Figure 5The first layer shown can quickly neutralize strong acids and alkalis in wastewater, rapidly bringing the pH value closer to the target range. Subsequent layers can precisely adjust residual trace amounts of acid and alkali, ensuring that the wastewater's pH meets strict discharge standards. The second motor 302 forms a transmission structure with the stirring blades 304 via the transmission rod 303, and the stirring blades 304 are arranged at equal intervals around the outer wall of the transmission rod 303. The reaction tank body 305 and the ball valve 306 form a communication structure, and the reaction tank body 305 and the effluent pipe 307 form a communication structure. As the wastewater flows through different layers sequentially, the reaction time with the treatment agents is extended, increasing the opportunity for sufficient contact between the wastewater and treatment agents such as acid-base regulators and flocculants, thereby improving the completion of various reactions and making the treatment effect more significant.

[0034] Working principle: First, the generated acidic and alkaline wastewater is transported to the reaction tank body 305 through the outer shell 201 and the larger filter screen 204 and the smaller filter screen 205. As it flows through the larger and smaller filter screens 204 and 205, larger impurities in the wastewater are filtered in layers, thus reducing the amount of impurities. After flowing into the reaction tank body 305, the pH level of the wastewater is monitored by the pH sensor 308. Then, the appropriate amount of chemicals is added based on the pH level. First, the water tank 101 is opened to allow clean water to enter through the cover 103. Then, a suitable amount of chemicals is added. The first motor 104 is then turned on. The first motor 104 drives the stirring rod 10 through the first threaded rod 105, nut 106, and second threaded rod 108. 9. Rotate the valve to melt and stir the drug evenly. Then, open the solenoid valve 107, and the drug solution inside the water tank 101 flows into the wastewater in the reaction tank body 305. At the same time, turn on the second motor 302. The second motor 302 drives the stirring plate 304 to rotate through the transmission rod 303, mixing the wastewater and the drug to accelerate the drug reaction. After reacting for a period of time in the first reaction tank, open the ball valve 306 by the handle, and the wastewater flows into the second reaction tank. The pH sensor 308 in the second reaction tank detects whether more drug solution needs to be added. At the same time, some ion precipitation reactions can be carried out in the second reaction tank. Then, open the ball valve 306 again, and the treated wastewater flows into the third reaction tank. The pH sensor 308 detects the wastewater again. After passing the test, the wastewater is discharged through the outlet pipe 307.
