Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an industrial wastewater treatment pond. Background Technology

[0002] Industrial wastewater refers to wastewater and waste liquid discharged during the production process. It contains industrial raw materials, intermediate products, by-products, and pollutants generated during the production process that are lost with the water. It is an important cause of environmental pollution, especially water pollution.

[0003] When treating industrial wastewater, treatment tanks are often used, and flocculants and other chemicals are added to them for treatment. However, after adding the chemicals, the tanks need to be left to stand, which wastes a lot of time, affects treatment efficiency, and the treatment process is monotonous and the treatment effect is not good. Utility Model Content

[0004] The main objective of this invention is to provide an industrial wastewater treatment pond that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an industrial wastewater treatment tank, comprising multiple sewage discharge mechanisms and multiple filter tanks, wherein a conveying mechanism is installed on the upper part of the multiple filter tanks via a fixed frame, the lower part of the sewage discharge mechanism is installed in the middle of the bottom wall of the filter tank, the lower part of the filter tank is connected to an annular connecting pipe via a solenoid valve, the annular connecting pipe is connected to the bottom of the secondary filter, and a drain pipe is installed on the upper middle part of the secondary filter;

[0006] The conveying mechanism includes a conveying pipe, a storage tank, a support, a servo motor, a belt, two pulleys, and a discharge pipe. The upper end of the discharge pipe is rotatably connected to the lower left end of the conveying pipe. One of the pulleys is fixedly connected to the upper outer periphery of the discharge pipe, and the other pulley is fixedly connected to the lower output end of the servo motor. The two ends of the belt are meshed with the outer periphery of the pulleys. The servo motor is mounted on the lower part of the support, which is located on the left side of the conveying pipe. The storage tank is mounted on the upper part of the conveying pipe.

[0007] Preferably, the plurality of filter pools are arranged in a circular pattern.

[0008] Preferably, the material conveying pipe has multiple mixing pipes in the middle, and two adjacent mixing pipes are arranged in a mirror image.

[0009] Preferably, the sewage discharge mechanism includes a sewage discharge pipe, a feed inlet, a discharge outlet, a vertical pole, auger blades, and a geared motor. The lower part of the sewage discharge pipe is installed in the middle of the filter tank. The feed inlet is located at the lower part of the sewage discharge pipe. The discharge outlet is installed at the upper part of the sewage discharge pipe. The upper end of the vertical pole is rotatably connected to the inner top wall of the sewage discharge pipe. The middle part of the auger blades is fixedly connected to the outer periphery of the vertical pole. The geared motor is installed at the upper part of the sewage discharge pipe. The lower output end of the geared motor passes through the sewage discharge pipe and is fixedly connected to the upper end of the vertical pole.

[0010] Preferably, the screw conveyor blades have a gradually decreasing spiral spacing from bottom to top, and the drain pipe has multiple drainage holes in the middle.

[0011] Preferably, the secondary filtration includes a filter barrel, a filter screen, and a delivery pump. The lower part of the filter barrel is installed at the output end of the delivery pump via a pipe, the input end of the delivery pump is installed in the middle of the annular connecting pipe, the filter screen is installed in the middle of the filter barrel, and one end of the drain pipe is fixedly connected to the middle of the upper side of the filter barrel.

[0012] Preferably, activated carbon is provided inside the filter barrel, and the activated carbon is located at the bottom of the filter screen.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The servo motor drives a connected pulley to rotate, which in turn drives another pulley via a belt. This causes the feed pipe to sequentially inject treated industrial wastewater into multiple filter tanks. The industrial wastewater containing flocculants or other chemicals then settles inside the filter tanks. The precipitated impurities are then sequentially discharged. Finally, the solenoid valves at the bottom of the filter tanks after the impurities have been discharged are opened sequentially, allowing the treated industrial wastewater to be discharged. This reduces the settling time of the industrial wastewater and greatly improves the treatment efficiency.

[0015] Flocculant or other chemicals are added to the conveying pipe through the storage tank. When the flocculant or other chemicals and industrial wastewater pass through the mixing pipe, they are mixed. Then, the geared motor drives the upright to rotate the auger blades, which causes the impurities settled at the bottom of the filter tank to enter the discharge pipe through the inlet. Finally, the rotating auger blades transport the impurities upward and discharge them through the discharge outlet. After the impurities inside the filter tank are discharged by its internal discharge mechanism, the solenoid valve at the bottom of the filter tank is opened to discharge the treated industrial wastewater. Then, the industrial wastewater is transported by the conveying pump into the filter tank, and then filtered through the filter screen and activated carbon. The treated industrial wastewater is discharged from the drain pipe. Through multiple treatment processes, the industrial wastewater treatment effect is better. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-6As shown, an industrial wastewater treatment tank includes multiple discharge mechanisms 2 and multiple filter tanks 7. A conveying mechanism 1 is mounted on the upper part of each filter tank 7 via a fixed frame. The discharge mechanisms 2 are installed in the middle of the bottom wall of each filter tank 7. The lower part of each filter tank 7 is connected to an annular connecting pipe 3 via a solenoid valve 6. The annular connecting pipe 3 is connected to the bottom of a secondary filter 4. A drain pipe 5 is installed on the upper middle part of the secondary filter 4. In summary, industrial wastewater is conveyed into the filter tank 7 through a conveying pipe 101 and a discharge pipe 107. Simultaneously, a control valve at the lower part of a storage tank 102 adds flocculant or other chemicals to the conveying pipe 101. When the flocculant or other chemicals and the industrial wastewater pass through a mixing pipe 108, they are mixed. Then, a servo motor 104 is driven, causing a connected pulley 106 to rotate. This, in turn, drives another pulley 106 via a belt 105, causing the discharge pipe 107 to sequentially inject treated industrial wastewater containing flocculant or other chemicals into the multiple filter tanks 7. The industrial wastewater containing the chemical solution is allowed to settle inside the filter tank 7, reducing the settling time and thus greatly improving the treatment efficiency. The drive motor 206 causes the upright 204 to rotate the auger blades 205, allowing impurities settled at the bottom of the filter tank 7 to enter the drain pipe 201 through the feed inlet 202. Finally, the rotating auger blades 205 transport the impurities upward. As the auger blades 205 gradually decrease in pitch from bottom to top, they compress the upward-transported impurities, causing excess water to be discharged from the drain hole 207, thus reducing water loss and resource waste. Finally, the impurities are discharged through the drain outlet 203. After the impurities inside the filter tank 7 are discharged by the internal drain mechanism 2, the solenoid valve 6 at the bottom of the filter tank 7 is opened, allowing the treated industrial wastewater to be discharged. Then, the industrial wastewater is transported by the transfer pump 403 into the filter tank 401, and then filtered through the filter screen 402. The treated industrial wastewater is discharged from the drain pipe 5.

[0025] The conveying mechanism 1 includes a conveying pipe 101, a storage tank 102, a support 103, a servo motor 104, a belt 105, two pulleys 106, and a discharge pipe 107. The upper end of the discharge pipe 107 is rotatably connected to the lower left side of the conveying pipe 101. One pulley 106 is fixedly connected to the upper outer periphery of the discharge pipe 107, and the other pulley 106 is fixedly connected to the lower output end of the servo motor 104. The two ends of the belt 105 are meshed with the outer periphery of the pulleys 106. The servo motor 104 is mounted on the lower part of the support 103, which is located on the left side of the conveying pipe 101. The storage tank 102 is also included. 2 is installed on the upper part of the conveying pipe 101. The industrial wastewater is transported into the filter tank 7 through the conveying pipe 101 and the discharge pipe 107. At the same time, the control valve at the lower part of the storage tank 102 adds flocculant or other chemicals into the conveying pipe 101. When the flocculant or other chemicals and the industrial wastewater pass through the mixing pipe 108, they will be mixed. Then, the servo motor 104 is driven, which drives the pulley 106 connected to it to rotate. In turn, the belt 105 drives another pulley 106 to rotate, so that the discharge pipe 107 sequentially injects the treated industrial wastewater into multiple filter tanks 7.

[0026] Multiple filter tanks 7 are arranged in a circular pattern, which allows treated industrial wastewater to be injected into the multiple filter tanks 7 sequentially when the feed pipe 107 rotates.

[0027] Multiple mixing pipes 108 are provided in the middle of the conveying pipe 101. Two adjacent mixing pipes 108 are arranged in a mirror image. When the industrial wastewater passes through the mixing pipe 108, it will rotate and mix with the flocculant or other liquids in the industrial wastewater. The mirrored mixing pipes 108 can change the rotation direction of the industrial wastewater, thereby better mixing the industrial wastewater and flocculant or other liquids.

[0028] The sewage discharge mechanism 2 includes a sewage discharge pipe 201, a feed inlet 202, a discharge outlet 203, a vertical pole 204, auger blades 205, and a reduction motor 206. The lower part of the sewage discharge pipe 201 is installed in the middle of the filter tank 7. The feed inlet 202 is located at the lower part of the sewage discharge pipe 201. The discharge outlet 203 is installed at the upper part of the sewage discharge pipe 201. The upper end of the vertical pole 204 is rotatably connected to the inner top wall of the sewage discharge pipe 201. The middle part of the auger blades 205 is fixedly connected to the outer periphery of the vertical pole 204. The geared motor 206 is installed on the upper part of the sewage pipe 201. The lower output end of the geared motor 206 passes through the sewage pipe 201 and is fixedly connected to the upper end of the upright 204. The geared motor 206 drives the upright 204 to drive the auger blades 205 to rotate, so that the impurities settled at the bottom of the filter tank 7 enter the sewage pipe 201 through the feed inlet 202, and are finally transported upward by the rotating auger blades 205, and finally discharged through the sewage outlet 203.

[0029] The screw conveyor blades 205 have a gradually decreasing spiral spacing from bottom to top. The sewage pipe 201 has multiple drainage holes 207 in the middle. As the screw conveyor blades 205 have a gradually decreasing spiral spacing from bottom to top, the impurities transported upward will be compressed, and the excess water will be discharged from the drainage holes 207, thereby reducing water loss and waste of resources.

[0030] The secondary filtration 4 includes a filter barrel 401, a filter screen 402, and a transfer pump 403. The lower part of the filter barrel 401 is connected to the output end of the transfer pump 403 via a pipe, and the input end of the transfer pump 403 is connected to the middle of the annular connecting pipe 3. The filter screen 402 is installed in the middle of the filter barrel 401. One end of the drain pipe 5 is fixedly connected to the upper middle part of the filter barrel 401. When the impurities inside the filter tank 7 are discharged by the internal sewage discharge mechanism 2, the solenoid valve 6 at the bottom of the filter tank 7 is opened to discharge the treated industrial wastewater. Then, through the transfer pump 403, the industrial wastewater enters the filter barrel 401 and is filtered by the filter screen 402. The treated industrial wastewater is then discharged from the drain pipe 5.

[0031] Activated carbon is installed inside the filter tank 401 and is located at the bottom of the filter screen 402. The activated carbon improves the filtration effect of industrial wastewater.

[0032] Working principle:

[0033] Industrial wastewater is conveyed into the filter tank 7 through the conveying pipe 101 and the discharge pipe 107. Simultaneously, a control valve at the bottom of the storage tank 102 adds flocculant or other chemicals to the conveying pipe 101. When the flocculant or other chemicals and the industrial wastewater pass through the mixing pipe 108, they mix. Then, the servo motor 104 is driven, causing the connected pulley 106 to rotate. This, in turn, drives another pulley 106 via the belt 105, causing the discharge pipe 107 to sequentially inject treated industrial wastewater into multiple filter tanks 7. The industrial wastewater containing flocculant or other chemicals then settles inside the filter tank 7, reducing the settling time and significantly improving the treatment efficiency. The drive motor 206 then drives the upright 204... The auger blades 205 rotate, causing impurities settled at the bottom of the filter tank 7 to enter the drain pipe 201 through the feed inlet 202. Finally, the rotating auger blades 205 transport them upward. As the auger blades 205 gradually reduce the spiral spacing from bottom to top, they compress the upward-transported impurities, causing excess water to be discharged from the drain hole 207, thereby reducing water loss and resource waste. Finally, the impurities are discharged through the drain outlet 203. After the impurities inside the filter tank 7 are discharged by its internal drain mechanism 2, the solenoid valve 6 at the bottom of the filter tank 7 is opened, allowing the treated industrial wastewater to be discharged. Then, through the conveying pump 403, the industrial wastewater enters the filter tank 401 and is filtered by the filter screen 402. The treated industrial wastewater is then discharged from the drain pipe 5.
