Specific implementation

[0025] The specific implementation of the utility model will be described in detail below in combination with the drawings, but it should be understood that the protection scope of the utility model is not limited by the specific implementation.

[0026] Reference Figures 1-2 As shown in the figure, a wastewater treatment tank is used for harmless treatment of acidic industrial wastewater, and the acidic wastewater is neutralized by injecting alkaline liquid into the neutralizing interval 2, so that the PH value of the acidic wastewater is increased to neutral or close to neutral. Subsequently, the foam generated in the neutralization reaction is eliminated by spraying defoaming agent through the overflow assembly, and the wastewater is injected into the treatment interval of other processes.

[0027] Reference Figures 4-5 As shown in the figure, in the process of neutralization reaction, the fan sleeve 5 with the fan 501 is installed on the wastewater liquid outlet and the neutralizing liquid liquid outlet, so that the sprayed liquid impacts the fan 501 and drives the fan 501 to rotate. The fan 501 installed on the wastewater liquid outlet and the neutralizing liquid liquid outlet rotates in the same direction, drives the mixed liquid in the neutralizing interval 2 to rotate, increases the reaction efficiency and reduces the phenomenon of incomplete reaction.

[0028] Reference Figures 1-3As shown, the wastewater treatment tank includes a tank body 1, which can be installed in a space of underground concrete pouring, or placed on the ground in the open air, and a support 101 is installed on one side of the tank body 1 to ensure stability. A neutralization chamber 2 is arranged in the tank body 1, which is used to mix the injected acidic wastewater and neutralizing liquid, so that they are fully contacted and reacted in the neutralization chamber 2. The bottom of the neutralization chamber 2 is provided with a hopper 201, and the neutralization chamber 2 is in the shape of a cube. The hopper 201 at the bottom of the neutralization chamber 2 can cooperate with the neutralization chamber 2 to facilitate the rotation and mixing of the liquid in the neutralization chamber 2, and when it is necessary to clean the space in the neutralization chamber 2, the bottom cover of the hopper 201 is opened to discharge the cleaning material in the neutralization chamber 2, that is, the hopper 201 is used for both the rotation of the mixed liquid in the neutralization chamber 2 and the cleaning of the interior of the neutralization chamber 2.

[0029] A second liquid inlet pipe 202 is installed in the neutralization chamber 2, and a first liquid inlet pipe 2011 is installed in the hopper 201. The second liquid inlet pipe 202 is used to inject alkaline neutralizing liquid into the neutralization chamber 2, and the first liquid inlet pipe 2011 is used to inject acidic industrial wastewater into the neutralization chamber 2. The alkaline neutralizing liquid and the acidic industrial wastewater are subjected to neutralization reaction in the neutralization chamber 2, and the mixed liquid flows into the next treatment area from the overflow assembly.

[0030] Reference Figures 4-6 As shown, the second liquid inlet pipe 202 and the first liquid inlet pipe 2011 are both provided with a joint assembly, which is used to change the longitudinal flow of the liquid to transverse spiral flow. A fan assembly is sleeved outside the joint assembly. When the liquid changed in flow direction by the joint assembly is sprayed, it impacts the fan assembly and drives the fan assembly to rotate around the joint assembly.

[0031] The joint assembly and the fan assembly are both provided with a matched liquid outlet. When the liquid transversely and spirally flows out of the joint assembly, it further changes the flow direction of the liquid and guides it to impact the fan 501 through the liquid outlet with an inclined angle on the fan assembly, so as to facilitate the rotation of the fan 501 to drive the liquid in the neutralization chamber 2 to rotate.

[0032] Reference Figures 4-6As shown, the joint assembly is used to connect the water pipe joint 6 to the second liquid inlet pipe 202 and the first liquid inlet pipe 2011, and the joint assembly changes the position of the liquid sprayed from below and sprays the liquid horizontally. The joint assembly comprises a water pipe clasp 603, a water pipe joint 6 and a connecting disc 7, and the water pipe clasp 603 and the connecting disc 7 are used to limit the fan sleeve 5 connected to the water pipe joint 6 and assist the rotation of the fan sleeve 5 around the water pipe joint 6. The water pipe joint 6 is fixedly connected to the water pipe clasp 603, the water pipe clasp 603 is connected to the second liquid inlet pipe 202, and the end of the water pipe joint 6 away from the water pipe clasp 603 is connected to the connecting disc 7. The water pipe joint 6 is provided with an internal thread 602, the connecting disc 7 is provided with an external thread 702, and the internal thread 602 and the external thread 702 are matched. The connecting disc 7 can be disassembled and assembled by using the internal thread 602 and the external thread 702. When the water flow direction does not need to be changed, the connecting disc 7 can be disassembled, and when the fan sleeve 5 needs to be installed, the connecting disc 7 can be tightened at the bottom of the water pipe joint 6 after installation, which not only limits the fan sleeve 5, but also changes the direction of the liquid spray.

[0033] Reference Figures 4-6 As shown, the water pipe joint 6 is connected to the fan sleeve 5, the fan sleeve 5 is installed between the water pipe clasp 603 and the connecting disc 7, and the fan sleeve 5 can be replaced by disassembling the connecting disc 7. The water pipe clasp 603 and the connecting disc 7 not only limit the fan sleeve 5, but also assist the rotation of the fan sleeve 5. The first rolling body 6031 is installed on the lower end surface of the water pipe clasp 603, and the first rolling groove 502 matched with the first rolling body 6031 is formed on the upper end surface of the fan sleeve 5. The first rolling body 6031 can move along the first rolling groove 502 and roll in the first rolling groove 502, which greatly reduces the friction of the upper end surface of the fan sleeve 5 when rotating around the water pipe joint 6. Similarly, the second rolling body 701 is installed on the upper end surface of the connecting disc 7, and the second rolling groove 503 matched with the second rolling body 701 is formed on the lower end surface of the fan sleeve 5. The second rolling body 701 moves along the inside of the second rolling groove 503 and rolls in the second rolling groove 503, which reduces the friction of the lower end surface of the fan sleeve 5 when rotating around the water pipe joint 6. The second rolling body 701 and the first rolling body 6031 move in the first rolling groove 502 and the second rolling groove 503 respectively, which greatly reduces the friction when the fan sleeve 5 rotates around the water pipe joint 6, and facilitates the rotation of the fan sleeve 5 around the water pipe joint 6.

[0034] Reference Figures 4-6As shown, the water pipe joint 6 is provided with a through groove 601, which is helical around and penetrates through the water pipe joint 6, so that the liquid is sprayed laterally through the through groove 601 on the water pipe joint 6. The fan sleeve 5 is provided with a liquid outlet 504 matched with the through groove 601, so that the liquid sprayed longitudinally from the through groove 601 is further changed in the direction of spraying through the liquid outlet 504 on the fan sleeve 5, so that the liquid is further sprayed in the direction of the fan blade 501 installed on the fan sleeve 5, facilitating the rotation of the fan sleeve 5 around the water pipe joint 6. The angle of the liquid outlet 504 is thirty to sixty degrees, and the fan sleeve 5 is fixedly connected with a plurality of fan blades 501 matched with the liquid outlet 504. The liquid sprayed obliquely from the liquid outlet 504 directly impacts on the fan blade 501 and drives the fan blade 501 to rotate counterclockwise. The liquid sprayed from the second liquid inlet pipe 202 and the first liquid inlet pipe 2011 drives the fan sleeve 5 installed on the second liquid inlet pipe 202 and the first liquid inlet pipe 2011 to rotate in the same direction, i.e. the fan blades 501 installed on the upper and lower fan sleeves 5 rotate counterclockwise. At this time, the mixed liquid in the neutralization interval 2 rotates and reacts uniformly in the neutralization interval 2, and the rotation of the fan blade 501 can also be driven by the rotation of the mixed liquid in the neutralization interval 2.

[0035] Reference Figure 7 As shown, the pool body 1 is provided with a settling interval 4, and the neutralized and reacted acidic wastewater further enters the settling interval 4 for settling. When the acidic industrial wastewater is neutralized and reacted, foam is easily produced on the mixed liquid. A partition plate 203 for purifying foam is installed between the neutralization interval 2 and the settling interval 4, and an overflow interval 3 is installed on the partition plate 203. The foam accumulated in the overflow interval 3 is eliminated by the defoaming agent sprayed in the overflow interval 3. An overflow port 301 is formed on the top of the side of the overflow interval 3 close to the neutralization interval 2, and the liquid lifted from the neutralization interval 2 flows into the overflow interval 3 through the overflow port 301. A liquid outlet 302 is formed on the bottom of the side of the overflow interval 3 close to the settling interval 4, and the liquid flowing into the overflow interval 3 flows out through the liquid outlet 302 close to the bottom of the overflow interval 3. Because the height of the liquid outlet 302 is lower than the height of the overflow port 301, the foam floating on the liquid stays inside the overflow interval 3, and the liquid below the foam flows into the settling interval 4. A water pipe 303 is installed on the overflow interval 3, and a plurality of spray ports 3031 are installed on the water pipe 303. The defoaming agent is sprayed in a fan shape through the spray ports 3031 installed on the overflow interval 3 to cover the foam in the overflow interval 3, so as to eliminate the foam. The lower end surface of the spray port 3031 is higher than the upper end surface of the overflow port 301, so as to ensure that the defoaming agent sprayed from the spray port 3031 uniformly covers the internal space of the overflow interval 3.

[0036] Specific use, from the second liquid inlet pipe 202 out of the neutralizing liquid and from the first liquid inlet pipe 2011 out of the acid industrial wastewater in the neutralization interval 2, and overflow interval 3 flow into the settling interval 4, while the overflow interval 3 to the neutralization interval 2 flow of mixed liquid foam elimination. The second liquid inlet pipe 202 and the first liquid inlet pipe 2011 on the water pipe joint 6 will be transversely sprayed out, and the liquid will be sprayed out from the water pipe joint 6 opening 504 at the fan blade 501 driven fan sleeve 5 rotating around the water pipe joint 6. The second liquid inlet pipe 202 and the first liquid inlet pipe 2011 on the fan sleeve 5 are rotated in the same direction, driving the liquid in the neutralization interval 2 to rotate and uniformly neutralize the reaction, and the acid industrial wastewater is treated. The treated acid wastewater flows from the overflow port 301 into the overflow interval 3 and flows from the liquid outlet 302 into the settling interval 4, and the floating foam is left in the overflow interval 3 and is eliminated under the action of the defoaming agent sprayed at the spray port 3031.

[0037] Compared with the prior art, the beneficial effects of the utility model are that the water pipe assembly with automatic stirring of the neutralization reaction tank during liquid outlet is installed in the neutralization reaction tank of the wastewater treatment tank, which can automatically stir the tank during the neutralization of the acid wastewater, increase the efficiency of the neutralization reaction and reduce the occurrence of uneven and incomplete neutralization reaction.
