Description

Technical Field

[0001] This utility model belongs to the field of amine-containing wastewater recycling and treatment technology, and specifically relates to an amine-containing wastewater recycling and treatment device. Background Technology

[0002] Amine-containing wastewater usually refers to industrial wastewater containing ammonia or ammonium ions. This type of wastewater usually comes from industries such as chemical, pharmaceutical, fertilizer production, leather processing, and food processing. If amine-containing wastewater is discharged directly without proper treatment, it will cause eutrophication pollution of water bodies, affecting the ecological environment and human health. Therefore, it is particularly important to recycle and treat amine-containing wastewater, and special amine-containing wastewater recycling and treatment equipment is required.

[0003] Existing amine-containing wastewater recovery and treatment devices typically involve adding a precipitant to react with ammonia or ammonium ions in the wastewater to generate precipitates, which are then transferred to a sedimentation tank for separation. However, in traditional treatment methods, the precipitant is often added directly to the wastewater in a quantitative manner and mixed using a stirring rack. This simple mixing method is not only slow but also prone to insufficient sedimentation, thus significantly reducing treatment efficiency. Utility Model Content

[0004] In view of this, the present invention provides a device for the recycling and treatment of amine-containing wastewater, which can achieve efficient separation and resource recovery of amine-containing wastewater through forced convection, and can better mix and react with precipitant and amine-containing wastewater, thereby improving the efficiency of amine-containing wastewater recycling and treatment.

[0005] To solve the above-mentioned technical problems, this utility model provides a device for the recycling and treatment of amine-containing wastewater, including a treatment tank and a recycling and treatment mechanism installed therein. The recycling and treatment mechanism includes a stirring frame rotatably connected to the treatment tank. The outer arc surface of the stirring frame is provided with several drain pipes. Each drain pipe has several outlets on its outer arc surface, each with an outlet head. The outlet heads distributed in a ring form a group, and the outlet ends of two groups of outlet heads face opposite directions. Each outlet head is provided with a one-way valve. The treatment tank is also provided with an air supply component, and one end of the treatment tank is also provided with a liquid supply component. That is, through forced convection, the efficient separation and resource recovery of amine-containing wastewater are achieved, which enables the precipitant and amine-containing wastewater to mix and react better, thereby improving the efficiency of amine-containing wastewater recycling and treatment.

[0006] Several scrapers are provided at the edge of the mixing rack, and all of the scrapers are in contact with the inner arc surface of the processing tank to prevent waste from adhering to the tank wall.

[0007] The gas supply assembly includes exhaust pipes symmetrically arranged at both ends of the inner cavity of the processing tank. Each exhaust pipe has an exhaust head in several outlets on its outer arc surface. The exhaust heads at the same end form a group, and the exhaust ends of two groups of exhaust heads face each other. The exhaust pipe has a vortex structure, and each exhaust head is equipped with a one-way valve, which serves as a gas transmission valve.

[0008] The air supply assembly also includes a transmission pipe installed on the processing tank. Both ends of the transmission pipe have air outlets that penetrate the inner arc surface of the processing tank and are connected to the air inlet of the corresponding exhaust pipe on the same side. The processing tank is equipped with an air pump, and the air outlet of the air pump is connected to the air inlet of the transmission pipe, thus providing air supply.

[0009] The liquid supply assembly includes a liquid supply channel located at one end of the stirring rack. Several liquid inlet holes are provided at the outer end of the inner arc surface of the liquid supply channel, which serve to transfer the precipitant.

[0010] The liquid supply assembly also includes a fixed sleeve located at one end of the treatment tank near the liquid inlet. The fixed sleeve is rotatably connected to the outer arc surface of the stirring frame. Several liquid inlets are located inside the fixed sleeve. A connecting pipe is provided in the opening on the outer arc surface of the fixed sleeve, which serves to connect with the external precipitant liquid pump.

[0011] A motor is installed at the end of the processing tank away from the fixed sleeve. The output shaft of the motor is fixedly connected to the end of the stirring frame, which provides the driving source for the synchronous rotation of the stirring frame and its auxiliary mechanisms.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. The motor and air supply components start synchronously. The motor output shaft rotates, driving the stirring frame and its auxiliary mechanisms to rotate synchronously. The stirring frame and its several drain pipes achieve efficient stirring of the amine-containing wastewater. The external precipitant liquid pump transmits the liquid into several drain pipes through the liquid supply components. Finally, the precipitant is sprayed out from the outlet end towards two sets of opposite outlet heads. At the same time, the air supply components have opposite outlet ends. The gas will cause the amine-containing wastewater to move from both ends towards the center of the treatment tank, while the precipitant is sprayed out from the center of the treatment tank towards both ends. Through forced convection, efficient separation and resource recovery of the amine-containing wastewater are achieved. This allows the precipitant and amine-containing wastewater to mix and react better, improving the efficiency of amine-containing wastewater recovery and treatment. The scraper at the edge of the stirring frame contacts the inner arc surface of the treatment tank during rotation, preventing waste from adhering to the tank wall.

[0014] 2. The air pump delivers gas to the exhaust pipe through the transmission pipe, and the gas outlet on the exhaust pipe discharges the gas. Since the outlets of the two sets of gas outlets face each other, the gas will cause the amine-containing wastewater to move from both ends toward the center of the treatment tank, which plays a role in efficient jetting and ensures that the amine-containing wastewater can be forced to flow.

[0015] 3. The relevant operators connect the connecting pipe to the supply end of the external precipitant pump. The external precipitant pump transmits the precipitant into several discharge pipes through the connecting pipe, fixed sleeve, inlet hole and supply channel. Finally, the precipitant is sprayed out from the outlet end towards two sets of outlet heads in opposite directions, which plays the role of transmitting precipitant. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a device for the recovery and treatment of amine-containing wastewater, such as... Figure 1-4 As shown: It includes a processing tank 100 and a recycling mechanism disposed therein. The recycling mechanism includes a stirring frame 200 rotatably connected to the processing tank 100. The outer arc surface of the stirring frame 200 is provided with a plurality of drain pipes 201. Each drain pipe 201 has a plurality of outlets on its outer arc surface, and each outlet is provided with an outlet head 202. The outlet heads 202 distributed in a ring form a group. The outlet ends of two groups of outlet heads 202 face opposite directions. Each outlet head 202 is provided with a one-way valve. The processing tank 100 is also provided with an air supply component. One end of the processing tank 100 is also provided with a liquid supply component. The edge of the stirring frame 200 is provided with a plurality of scrapers 203. The scrapers 203 are all in contact with the inner arc surface of the processing tank 100.

[0023] The motor 500 and the air supply component start synchronously. The output shaft of the motor 500 rotates, driving the stirring frame 200 and its auxiliary mechanisms to rotate synchronously. The stirring frame 200 and its several drain pipes 201 achieve efficient stirring of the amine-containing wastewater. The external precipitant liquid pump transmits the liquid into the several drain pipes 201 through the liquid supply component. Finally, the precipitant is sprayed out from the outlet end towards two sets of outlet heads 202 in opposite directions. At the same time, the air outlet end of the air supply component faces opposite directions. The gas will cause the amine-containing wastewater to move from both ends towards the center of the treatment tank 100, while the precipitant is sprayed out from the center of the treatment tank 100 towards both ends. Through forced convection, efficient separation and resource recovery of the amine-containing wastewater are achieved. The precipitant and the amine-containing wastewater can be better mixed and reacted, improving the efficiency of amine-containing wastewater recovery and treatment. The scraper 203 at the edge of the stirring frame 200 contacts the inner arc surface of the treatment tank 100 during rotation to prevent waste from adhering to the tank wall.

[0024] like Figure 1-4 As shown, the air supply assembly includes exhaust pipes 300 symmetrically arranged at both ends of the inner cavity of the processing tank 100. Each of the several air outlets on the outer arc surface of the exhaust pipe 300 is provided with an air outlet head 301. The air outlet heads 301 at the same end form a group. The air outlet ends of two groups of air outlet heads 301 face each other. The exhaust pipe 300 has a vortex structure. Each air outlet head 301 is provided with a one-way valve. The air supply assembly also includes a transmission pipe 302 installed on the processing tank 100. The air outlet ends of the transmission pipe 302 penetrate the inner arc surface of the processing tank 100 and are connected to the air inlet end of the exhaust pipe 300 on the same side. An air pump 303 is installed on the processing tank 100. The air outlet end of the air pump 303 is connected to the air inlet end of the transmission pipe 302.

[0025] The air pump 303 delivers gas to the exhaust pipe 300 through the transmission pipe 302. The air outlet 301 on the exhaust pipe 300 discharges the gas. Since the outlet ends of the two sets of air outlets 301 face each other, the gas will cause the amine-containing wastewater to move from both ends toward the center of the treatment tank 100, which plays a role in efficient jetting and ensures that the amine-containing wastewater can be forced to flow.

[0026] like Figure 1-4 As shown, the liquid supply assembly includes a liquid supply channel 400 disposed at one end of the stirring frame 200. The outer end of the inner arc surface of the liquid supply channel 400 is provided with a plurality of liquid inlet holes 401, which are evenly distributed in a ring. The liquid supply assembly also includes a fixing sleeve 402 disposed at one end of the processing tank 100 near the liquid inlet holes 401. The fixing sleeve 402 is rotatably connected to the outer arc surface of the stirring frame 200. The plurality of liquid inlet holes 401 are all located inside the fixing sleeve 402. A connecting pipe 403 is provided in the opening provided on the outer arc surface of the fixing sleeve 402.

[0027] The relevant operators connect the connecting pipe 403 to the supply end of the external precipitant pump. The external precipitant pump transmits the precipitant into several drain pipes 201 through the connecting pipe 403, the fixed sleeve 402, the inlet hole 401 and the supply channel 400. Finally, the precipitant is sprayed out from the outlet end towards two sets of outlet heads 202 in opposite directions, which plays the role of transmitting the precipitant.

[0028] like Figure 1-2 As shown, a motor 500 is provided at the end of the processing tank 100 away from the fixed sleeve 402, and the output shaft of the motor 500 is fixedly connected to the end of the stirring frame 200.

[0029] When motor 500 starts, its output shaft drives the stirring rack 200 and its auxiliary mechanisms to rotate synchronously, thus providing a driving source for the synchronous rotation of the stirring rack 200 and its auxiliary mechanisms.

[0030] The working principle of the amine-containing wastewater recovery and treatment device provided by this utility model is as follows: First, the relevant operators connect the connecting pipe 403 to the supply end of the external precipitant pump, and then simultaneously pour the amine-containing wastewater into the treatment tank 100. Subsequently, the motor 500 and the air pump 303 start synchronously. The output shaft of the motor 500 rotates, driving the stirring frame 200 and its auxiliary mechanisms to rotate synchronously. The stirring frame 200 and its several drain pipes 201 achieve efficient stirring of the amine-containing wastewater. The external precipitant pump transmits the liquid into the several drain pipes 201 through the connecting pipe 403, the fixing sleeve 402, the inlet hole 401, and the supply channel 400. Finally, the liquid flows out from the outlet end towards two sets of outlet heads in opposite directions. 202 sprays out the precipitant. At the same time, the air pump 303 delivers gas to the exhaust pipe 300 through the transmission pipe 302. The gas outlet 301 on the exhaust pipe 300 discharges the gas. Since the outlet ends of the two sets of gas outlets 301 face each other, the gas will cause the amine-containing wastewater to move from both ends toward the center of the treatment tank 100, while the precipitant is sprayed from the center of the treatment tank 100 to both ends. Through forced convection, the efficient separation and resource recovery of the amine-containing wastewater are achieved, which can make the precipitant and the amine-containing wastewater mix and react better, thereby improving the efficiency of amine-containing wastewater recovery and treatment. The scraper 203 at the edge of the stirring rack 200 contacts the inner arc surface of the treatment tank 100 during rotation to prevent waste from adhering to the tank wall.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
