Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a zero-discharge evaporation device for electroplating wastewater. Background Technology

[0002] The electroplating wastewater zero-discharge evaporation device is a type of equipment used to treat wastewater from the electroplating industry. It aims to achieve zero discharge of wastewater through evaporation technology, so that the treated wastewater is no longer discharged into the external environment, thus reducing environmental pollution.

[0003] When treating wastewater, electroplating wastewater zero-discharge evaporation devices typically require strict evaporation to separate water into water vapor and other impurities in the waste liquid. If the device can be strictly sealed and locked during evaporation, leakage of gas and vapor during the evaporation process can be effectively prevented. Therefore, we propose an electroplating wastewater zero-discharge evaporation device. Summary of the Invention

[0004] The purpose of this utility model is to provide a zero-discharge evaporation device for electroplating wastewater. By pressing down on the sealing cover, the sealing cover compresses the spring, and then the spring rebounds, causing the connecting ring to push the rubber ring, tightly adhering the rubber ring to the evaporation tank, thus solving the problem of sealing the device during evaporation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a zero-discharge evaporation device for electroplating wastewater, including a base, an evaporation tank fixedly connected to the inner wall of the base, a sealing mechanism on the evaporation tank, and a rapid condensation mechanism on the base.

[0007] The sealing mechanism includes a sealing cover, a connecting block fixedly connected to the outer surface of the evaporation tank, a bolt threadedly connected to the inner wall of the connecting block, a motor frame fixedly connected to the top of the sealing cover, a first motor fixedly connected to the inner wall of the motor frame, a stirring rod fixedly connected to the output shaft of the first motor via a coupling, a rubber ring slidably connected to the outer surface of the evaporation tank, a connecting ring fixedly connected to the top of the rubber ring, a sliding rod fixedly connected to the top of the connecting ring, a spring fixedly connected to the outer surface of the sealing cover, and a heater fixedly connected to the inner wall of the base.

[0008] Furthermore, the outer surface of the sealing cap is slidably connected to the outer surface of the evaporation tank, two connecting blocks are provided, the inner wall of the connecting block is slidably connected to the outer surface of the sealing cap, the outer surface of the bolt is rotatably connected to the inner wall of the sealing cap, the outer surface of the stirring rod is rotatably connected to the inner wall of the sealing cap, and the outer surface of the rubber ring is slidably connected to the inner wall of the sealing cap.

[0009] Furthermore, the outer surface of the connecting ring is slidably connected to the inner wall of the sealing cover, a plurality of sliding rods are provided, the outer surface of the sliding rods is slidably connected to the inner wall of the sealing cover, a plurality of springs are provided, the end of the spring away from the sealing cover is fixedly connected to the top of the connecting ring, and the inner side of the spring is sleeved with the outer surface of the sliding rod.

[0010] Furthermore, the rapid condensation mechanism includes a collection frame slidably connected to the inner wall of the evaporation tank, a connecting pipe fixedly connected to the inner wall of the sealing cover, and a shell slidably connected to the outer surface of the connecting pipe.

[0011] Furthermore, the bottom of the housing is fixedly connected to the outer surface of the base, a rotating door is rotatably connected to the inner wall of the housing, and a fixing block is slidably connected to the outer surface of the rotating door. There are two fixing blocks in total.

[0012] Furthermore, the inner wall of the fixing block is threaded with a second bolt, the outer surface of the second bolt is rotatably connected to the inner wall of the revolving door, the inner wall of the housing is slidably connected with a water storage tank, the inner wall of the housing is fixedly connected with a connecting cylinder, and the side of the housing away from the revolving door is fixedly connected with a second motor frame.

[0013] Furthermore, a second motor is fixedly connected to the inner wall of the motor frame, and a fan is fixedly connected to the output shaft of the second motor via a coupling. A dustproof plate is rotatably connected to the outer surface of the fan.

[0014] Furthermore, the outer surface of the dustproof plate is fixedly connected to the inner wall of the connecting cylinder, a limit block is fixedly connected to the inner wall of the connecting cylinder, and the inner wall of the limit block is rotatably connected to the outer surface of the fan.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a spring. When the sealing cover is placed on the evaporation tank, the rubber ring contacts the evaporation tank. Pressing the sealing cover downwards causes it to slide on the sliding rod, simultaneously compressing the spring. Once the sealing cover slides into the connecting block, the bolt is tightened into the connecting block. This sealing cover, which compresses the spring, achieves a strict seal on the evaporation tank during evaporation, effectively preventing gas and steam leakage. It also prevents harmful substances from entering the environment, avoiding the harm of toxic gases to operators and the surrounding environment, and ensuring the safety of the equipment.

[0017] 2. This utility model incorporates a fan. The evaporated water vapor enters the housing through the connecting pipe. At this time, the second motor causes the fan to rotate inside the connecting cylinder. The fan then rapidly cools the water vapor, causing it to condense into water and fall into the water storage tank. The bolt two can then be unscrewed from the fixing block and the rotating door. The second motor, which drives the fan to rotate, effectively converts the evaporated water vapor into water and recovers the water through the water storage tank. This improves the wastewater recovery rate, reduces water waste, and helps achieve the goal of zero emissions.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-8 As shown, this utility model is a zero-discharge evaporation device for electroplating wastewater, including a base 101, an evaporation tank 102 fixedly connected to the inner wall of the base 101, a sealing mechanism 2 provided on the evaporation tank 102, and a rapid condensation mechanism 3 provided on the base 101. The evaporation tank 102 can be sealed by the sealing mechanism 2, and the sealing mechanism 2 can also be stirred during heating to make the wastewater evenly heated. Then the rapid condensation mechanism 3 can quickly condense and collect the water vapor.

[0032] The sealing mechanism 2 includes a sealing cover 201. A connecting block 202 is fixedly connected to the outer surface of the evaporation tank 102. A bolt 203 is threadedly connected to the inner wall of the connecting block 202. A motor frame 204 is fixedly connected to the top of the sealing cover 201. A first motor 205 is fixedly connected to the inner wall of the motor frame 204. The motor frame 204 fixes the first motor 205 so that the first motor 205 will not rotate during operation, ensuring that the device can perform normal stirring, thereby making the wastewater evenly heated. The output shaft of the first motor 205 is fixedly connected to a stirring rod 206 through a coupling. A rubber ring 207 is slidably connected to the outer surface of the evaporation tank 102. The top of the rubber ring 207 is fixed. A connecting ring 208 is connected, and a slide rod 209 is fixedly connected to the top of the connecting ring 208. The slide rod 209 restricts the movement of the sealing cover 201. When the sealing cover 201 is pressed down, the slide rod 209 ensures that the sealing cover 201 can only slide along the slide rod 209, preventing the sealing cover 201 from shifting during movement. A spring 210 is fixedly connected to the outer surface of the sealing cover 201, and a heater 211 is fixedly connected to the inner wall of the base 101. The outer surface of the sealing cover 201 is slidably connected to the outer surface of the evaporation tank 102. Two connecting blocks 202 are provided. When the sealing cover 201 is pressed down, it will compress the spring 210 through the connecting ring 208, thereby causing the spring 210 to... The system is designed to spring back, ensuring the rubber ring 207 is tightly fitted onto the evaporator 102.

Several springs 210 are provided. The end of the spring 210 away from the sealing cover 201 is fixedly connected to the top of the connecting ring 208. The inner side of the spring 210 is sleeved with the outer surface of the slide rod 209. The slide rod 209 restricts the movement trajectory of the spring 210 to prevent the spring 210 from tilting or deviating during the movement, and ensures that the rubber ring 207 can seal the evaporation tank 102.

[0033] The rapid condensation mechanism 3 includes a collection frame 302 slidably connected to the inner wall of the evaporation tank 102, a connecting pipe 301 fixedly connected to the inner wall of the sealing cover 201, a housing 303 slidably connected to the outer surface of the connecting pipe 301, and the bottom of the housing 303 fixedly connected to the outer surface of the base 101. After the water vapor is completely evaporated, other substances in the waste liquid will remain in the collection frame 302. The collection frame 302 can be removed from the evaporation tank 102 to collect and process these substances. A rotating door 304 is rotatably connected to the inner wall of the housing 303, and a fixing block 305 is slidably connected to the outer surface of the rotating door 304. There are two fixing blocks 305. Bolt 306 is threaded into the wall and can be tightened into the fixing block 305. At this time, bolt 306 fixes the rotating door 304 to prevent condensed water vapor from flowing out of the housing 303. The outer surface of bolt 306 is rotatably connected to the inner wall of the rotating door 304. A water storage tank 307 is slidably connected to the inner wall of the housing 303. A connecting cylinder 308 is fixedly connected to the inner wall of the housing 303. A motor frame 309 is fixedly connected to the side of the housing 303 away from the rotating door 304. The condensed water vapor will enter the water storage tank 307. Then the water storage tank 307 can be removed from the housing 303 to collect the condensate.

[0034] A second motor 310 is fixedly connected to the inner wall of the second motor frame 309. The output shaft of the second motor 310 is fixedly connected to a fan 311 via a coupling. A dustproof plate 313 is rotatably connected to the outer surface of the fan 311. The second motor frame 309 fixes the second motor 310 to prevent it from rotating during operation, ensuring that the device can transmit power normally. The outer surface of the dustproof plate 313 is fixedly connected to the inner wall of the connecting cylinder 308. A limit block 312 is fixedly connected to the inner wall of the connecting cylinder 308. The inner wall of the limit block 312 is rotatably connected to the outer surface of the fan 311.

[0035] One specific application of this embodiment is:

[0036] When the equipment is needed, wastewater is first poured into the evaporation tank 102. Then, the sealing cap 201 is placed on the evaporation tank 102, at which point the rubber ring 207 will contact the evaporation tank 102. The sealing cap 201 is then pressed down, causing it to slide on the slide rod 209. Simultaneously, the sealing cap 201 compresses the spring 210. When the sealing cap 201 slides into the connecting block 202, the bolt 203 is tightened into the connecting block 202, fixing the sealing cap 201 in place. Due to the action of the spring 210, the rubber ring 207 is tightly fitted onto the evaporation tank 102, sealing it. This achieves a strict seal during evaporation, effectively preventing gas and steam leakage and preventing harmful substances from entering the environment. It also avoids the harm of toxic gases to operators and the surrounding environment, ensuring the safety of the equipment. The heater can then be started. 211 and the first motor 205. At this time, the heater 211 heats the inside of the evaporation tank 102. Then, the first motor 205 drives the stirring rod 206 to rotate inside the evaporation tank 102 to stir the waste liquid. The evaporated water vapor will enter the shell 303 through the connecting pipe 301. At this time, the second motor 310 will make the fan 311 rotate inside the connecting cylinder 308. Then, the fan 311 will quickly cool the water vapor, causing it to condense into water and fall into the water storage tank 307. This achieves the goal of quickly condensing water vapor into water, effectively converting the evaporated water vapor into water, and recovering the water through the water storage tank 307. This can improve the wastewater recovery rate, reduce water waste, and help achieve the goal of zero discharge. Then, the bolt 206 can be unscrewed from the fixing block 305 and the rotating door 304, and the rotating door 304 can be rotated to open the shell 303. Then, the water storage tank 307 can be pulled out from the shell 303 to collect the water.
