Description

Technical Field

[0001] The invention belongs to the technical field of vacuum impregnation, and in particular to a method and a device for recovering and treating a spray cleaning liquid used for vacuum impregnation. Background Art

[0002] Impregnation, also known as dipping, soaking, and penetration, is a microporous penetration sealing process. The sealing medium is infiltrated into the micropores by natural penetration, vacuuming, and pressurization to fill the gaps, and then the sealing medium in the gaps is solidified by room temperature, cooling, or heating to achieve the effect of sealing the gaps. At present, most of the workpieces are impregnated by vacuum, and after the vacuum impregnation operation, the workpiece with the impregnant attached needs to be sprayed and cleaned twice. Generally, the impregnation processing operation of the workpiece is completed in the order of impregnation-spinning-first spray cleaning-second spray cleaning-thermal curing treatment. In the prior art, the cleaning liquid after two spray cleanings is generally recovered into a separation box, and then a separation agent is added to mix with the cleaning liquid to achieve phase separation, so that the upper layer of the impregnant and the lower layer of the cleaning water can be recovered separately. However, this recycling and processing method of the spray cleaning liquid has the following problems:

[0003] (1) In the prior art, the cleaning liquid after multiple spray cleaning is usually stored in a separation box and then a separation agent is added for separation. This operation makes it impossible to recycle the cleaning liquid in a timely manner;

[0004] (2) Since the separation agent has chemical components, the separation agent components remain in the impregnation agent and washing water after separation, which results in that the impregnation agent and washing water after separation cannot be directly recycled into the impregnation tank and spray tank for use. The separation agent often needs to be processed again, which makes the process complicated and reduces the recovery efficiency.

[0005] (3) After the impregnation agent and the cleaning water are separated, there is an adjacent position between the two. The impregnation agent and the cleaning water cannot be completely separated here. Regardless of whether the impregnation liquid recovery mechanism recovers the impregnation agent or the cleaning water recovery mechanism recovers the cleaning water, the solution recovered by one of the recovery mechanisms may contain other components. The solution mixed with other components still needs to be processed again after recovery, resulting in a poor recovery effect. Summary of the invention

[0006] Purpose of the invention: To provide a method and device for recycling spray cleaning liquid used for vacuum impregnation, so as to improve the recycling efficiency of the cleaning liquid after spray cleaning.

[0007] Technical solution:

[0008] A method for recovering and treating a spray cleaning liquid used for vacuum impregnation, specifically comprising the following steps:

[0009] S1: The workpiece that has completed the impregnation operation in the vacuum impregnation equipment is moved into the first spray chamber opened in the first spray tank. The first spray assembly arranged in the first spray chamber is connected to the first water storage chamber through the first spray cleaning water transmission mechanism. The first water storage chamber is arranged in the first spray tank and is connected to the municipal water pipeline. In the first cycle, the water source for the spray cleaning operation in the first spray tank is completely derived from the municipal water. The municipal water is input into the first water storage chamber through the municipal water pipeline. The first spray cleaning water transmission mechanism arranged on the first spray tank inputs the municipal water in the first water storage chamber into the first spray assembly, and performs the first spray cleaning operation on the workpiece located in the first spray chamber. A type of cleaning liquid generated by the first spray cleaning operation enters the recovery tank located below the first spray tank through the first cleaning liquid transmission mechanism. After the first spray cleaning operation The workpiece being processed is moved by the robot into the second spray chamber provided in the second spray tank for further cleaning. The second spray assembly provided in the second spray chamber is connected to the second water storage chamber through the second spray cleaning water transmission mechanism. The second water storage chamber is provided in the second spray tank and is connected to the municipal water pipeline. In the first cycle, the water source for the spray cleaning operation in the second spray tank is completely derived from municipal water. The municipal water is stored in the second water storage chamber through the municipal water pipeline. The second spray cleaning water transmission mechanism provided on the second spray tank inputs the municipal water in the second water storage chamber into the second spray assembly, and performs a second spray cleaning operation on the workpiece located in the second spray chamber. The second type of cleaning liquid generated by the second spray cleaning operation enters the recovery tank through the second cleaning liquid transmission mechanism. The workpiece that has undergone the second spray cleaning operation is transferred to the next process.

[0010] S2: In the first cycle, the first type of cleaning liquid and the second type of cleaning liquid are sequentially entered into the four processing chambers opened in the recovery and processing tank. After the volume of the cleaning liquid in the first processing chamber reaches the first preset volume, it is switched to the second processing chamber. When the volume of the cleaning liquid in the second processing chamber reaches the first preset volume, it is switched to the third processing chamber. When the volume of the cleaning liquid in the third processing chamber reaches the first preset volume, at this time, the first water storage chamber and the second water storage chamber respectively store the second preset volume of municipal water, the municipal water pipeline is closed, and the first type of cleaning liquid and the second type of cleaning liquid do not enter the fourth processing chamber. The first cycle ends and enters the second cycle, wherein the time for the cleaning liquid in a single processing chamber to reach the first preset volume is half of the time required for the single processing chamber to be heated and kept at a constant temperature, and the sum of the volumes of the first water storage chamber and the second water storage chamber is greater than or equal to the sum of the first preset volume and the two second preset volumes;

[0011] S3: In the second cycle, when the first preset volume of cleaning liquid is injected into the third processing chamber, the cleaning liquid in the first processing chamber is allowed to stand still. The cleaning liquid in the first processing chamber is heated and allowed to stand at a constant temperature, and then separated to obtain upper and lower layered impregnation liquid, water-impregnation mixed liquid and water liquid. The impregnation liquid, the water liquid and the water-impregnation mixed liquid are sequentially extracted by the impregnation liquid recovery mechanism, the second cleaning water recovery mechanism and the first cleaning water recovery mechanism installed on the recovery tank until the first processing chamber is emptied. The output ends of the impregnation liquid recovery mechanism, the second cleaning water recovery mechanism and the first cleaning water recovery mechanism are respectively connected to the vacuum impregnation equipment, the second water storage chamber and the first water storage chamber, and the water-impregnation mixed liquid enters the first water storage chamber. The water-impregnation mixed liquid entering the first water storage chamber is used for the subsequent workpiece to be subjected to the second impregnation treatment. In one spray cleaning operation, the water enters the second water storage chamber, and the water entering the second water storage chamber is used to perform a second spray cleaning operation on subsequent workpieces. The first type of cleaning liquid discharged from the first spray chamber and the second type of cleaning liquid discharged from the second spray chamber enter the fourth processing chamber. When the volume of the cleaning liquid in the fourth processing chamber reaches the first preset volume, the cleaning liquid in the second processing chamber is left to stand still. The cleaning liquid in the second processing chamber is recycled and reused according to the treatment process of the cleaning liquid in the first processing chamber. The recycled water and water-infiltration mixed liquid are again discharged from the first spray chamber and the second spray chamber into the first processing chamber, and so on. By switching the four processing chambers in the second cycle, the city water used for spraying in the first cycle is recycled to achieve the purpose of recycling the spray cleaning liquid.

[0038] Beneficial effects of the present invention:

[0039] (1) A recovery tank is fixedly arranged below the spray tank, and an average of four processing chambers are arranged in the recovery tank, so that the cleaning liquid after two spray cleanings of different batches of workpieces can be recovered and stored. The four processing chambers can be switched for use. In the first cycle, when the first three processing chambers are filled with the first preset volume of cleaning liquid, while the cleaning liquid enters the fourth processing chamber, the cleaning liquid in the first processing chamber has been separated and recovered and input into the spray tank for spraying operation. At this time, the municipal water pipeline is closed and no external water source needs to be input. In the second cycle, the municipal water input before the municipal water pipeline is closed can be recycled. No municipal water needs to be input in the second cycle, which effectively improves the recovery rate of the cleaning liquid. While not affecting the cleaning effect, it can also achieve the purpose of saving water resources;

[0040] (2) A heating component is provided in the processing chamber, and the cleaning liquid entering the processing chamber is heated and kept at a constant temperature by the heating component for separation. Since the four switchable processing chambers can meet the time requirements for heating and keeping at a constant temperature, there is no need to use a separation agent, and thus there is no need to process the separation agent, so that the purity of the recycled cleaning water is better;

[0041] (3) After the cleaning liquid in the processing chamber is separated, the upper and lower layers of the impregnation liquid, the water-impregnation mixed liquid and the water liquid are obtained. The water liquid is located below the water-impregnation mixed liquid. It is farther away from the impregnation liquid and has a higher purity, which meets the requirements of the second spray cleaning. Therefore, it is recycled into the second spray tank to perform the second spray cleaning operation on the workpiece. The water-impregnation mixed liquid still contains a small amount of impregnation liquid, so it can be recycled into the first spray tank with a lower purity requirement to perform the first spray cleaning operation on the workpiece. The impregnation liquid can be recycled into the vacuum impregnation equipment to participate in the impregnation operation. This recycling method maximizes the utilization rate of the cleaning liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] S2.1: A heating assembly 42 is provided in each of the four processing chambers 41. The heating assembly 42 is used to heat the cleaning liquid entering the processing chamber 41. The heating assembly 42 includes a heating plate.

[0063] S3: In the second cycle, when the first preset volume of cleaning liquid is injected into the third processing chamber 41, the cleaning liquid in the first processing chamber 41 is allowed to stand, and the cleaning liquid in the first processing chamber 41 is heated and allowed to stand at a constant temperature, and then separated to obtain upper and lower layered impregnation liquid, water-impregnation mixed liquid and water liquid, and the impregnation liquid, the water liquid and the water-impregnation mixed liquid are sequentially extracted by the impregnation liquid recovery mechanism 6, the second cleaning water recovery mechanism 8 and the first cleaning water recovery mechanism 7 installed on the recovery tank 4 until the first processing chamber 41 is emptied, and the output ends of the impregnation liquid recovery mechanism 6, the second cleaning water recovery mechanism 8 and the first cleaning water recovery mechanism 7 are respectively connected to the vacuum tank 4.

After the cleaning liquid is left to stand, the cleaning liquid in the second processing chamber 41 is recycled and reused according to the processing process of the cleaning liquid in the first processing chamber 41, and the recycled water liquid and water-infiltration mixed liquid are again discharged from the first spray chamber 111 and the second spray chamber 121 into the first processing chamber 41, and so on. By switching the four processing chambers 41 in the second cycle, the municipal water sprayed in the first cycle is recycled to achieve the purpose of recycling the spray cleaning liquid. For example, in the first cycle, before the three processing chambers 41 reach the first preset volume, the municipal water is continuously input into the first water storage chamber 115 and the second water storage chamber 125 through the municipal water pipe 9. In order to meet the needs of two spray cleaning operations for the first three groups of workpieces, when the third processing chamber 41 in the first cycle has also reached the first preset volume, the cleaning liquid in the first processing chamber 41 and the second processing chamber 41 that has reached the first preset volume is in a heating constant temperature static process. At this time, the fourth processing chamber 41 is empty, and the first water storage chamber 115 and the second water storage chamber 125 still retain the second preset volume of municipal water. The municipal water pipeline 9 is closed and no municipal water is introduced. The cleaning liquid in the first processing chamber 41 is static, and the impregnation liquid, water-impregnation mixed liquid and water liquid generated by the static are respectively recycled into the vacuum impregnation equipment (not shown in the figure), the first water storage chamber 115 and the second water storage chamber 125. In this recycling process,The second preset volume of municipal water in the two water storage chambers is respectively used for spray cleaning operation on the workpieces in the spray chambers through the corresponding spray components, and the continuity of the spray cleaning operation can be maintained before the water-infiltration mixture and the water enter the two water storage chambers. If the volumes of the first water storage chamber 115 and the second water storage chamber 125 are 1.25 tons respectively, the first preset volume is 2 tons of water, the second preset volume is 0.25 tons of water, and the volume of a single processing chamber 41 is greater than 2 tons, the first spray cleaning of the workpiece produces 1 ton of Class I cleaning liquid, and the second spray cleaning operation of the workpiece produces 1 ton of Class II cleaning liquid. In the first cycle, when 2 tons of cleaning liquid are respectively injected into the three processing chambers 41 to reach the first preset volume, there are 6 tons of cleaning liquid in the three processing chambers 41, and the two water storage chambers There is 0.5 tons of city water, and the time for extracting 2 tons of cleaning liquid into the processing chamber 41 to reach the first preset volume is preset to half an hour, and the heating and standing time of 2 tons of cleaning liquid is 4 hours to obtain the impregnation liquid located on the upper layer and the water-impregnation mixed liquid and water liquid with the same volume. The time for the same batch of workpieces to complete two spray cleanings in sequence is 2 hours. At the same time, the cleaning liquid generated during the two spray cleaning processes is also discharged into the processing chamber 41. The time for the cleaning liquid to be discharged into the processing chamber 41 to reach the first preset volume is half an hour, and this half an hour is included in the 2 hours of completing the two spray cleanings. This time includes the time for the pump body and the valve to switch and the time for taking and placing the workpieces. When the first batch of workpieces are completed after two spray cleaning operations and the generated cleaning liquid is also discharged into the first processing chamber When the first preset volume is reached in 41, the time for two spray cleanings and the time for the generated 2 tons of water to be discharged into the first processing chamber 41 is 2 hours in total. At this time, the second batch of workpieces starts the first spray cleaning operation, and the cleaning liquid in the first processing chamber 41 starts to be heated and allowed to stand for 4 hours. When the second batch of workpieces complete the two spray cleaning operations and the generated 2 tons of cleaning liquid enters the second processing chamber 41, it takes a total of 2 hours and reaches the first preset volume, the third batch of workpieces starts the first spray cleaning operation. At this time, the cleaning liquid in the first processing chamber 41 has been standing for 2 hours. When the third batch of workpieces completes the two spray cleaning operations of 2 hours and discharges the first preset volume of cleaning liquid into the third processing chamber 41, the first processing chamber 41 The cleaning liquid in the first processing chamber 41 has been standing for 4 hours, the cleaning liquid in the second processing chamber 41 has been standing for 2 hours, the municipal water pipe 9 is closed, and the fourth batch of workpieces begins to be sprayed with the municipal water of the second preset volume. At this time, the cleaning liquid in the first processing chamber 41 is recycled into the vacuum impregnation equipment (not shown in the figure), the first water storage chamber 115 and the second water storage chamber 125 while the fourth batch of workpieces are being sprayed and cleaned. The recovered solution entering the first water storage chamber 115 and the second water storage chamber 125 is used in conjunction with the municipal water of the second preset volume to clean the fourth batch of workpieces. When the cleaning liquid in the first processing chamber 41 is emptied in about half an hour, the fourth batch of workpieces has also completed the spray cleaning operation of about half an hour. The cleaning liquid in the second processing chamber 41 is left standing for 2 and a half hours.The cleaning liquid in the third processing chamber 41 is left to stand for half an hour. When the fourth batch of workpieces completes two spray cleaning operations for 2 hours and the first preset volume of cleaning liquid is discharged into the fourth processing chamber 41, the cleaning liquid in the second processing chamber 41 has been left to stand for 4 hours, and the cleaning liquid in the third processing chamber 41 is left to stand for 2 hours. At this time, the cleaning liquid in the second processing chamber 41 is recycled into the vacuum impregnation equipment (not shown in the figure), the first water storage chamber 115 and the second water storage chamber 125 respectively while the fifth batch of workpieces are being spray cleaned. The recovered solution entering the first water storage chamber 115 and the second water storage chamber 125 cooperates with the spray cleaning of the fifth batch of workpieces to provide a water source. When the cleaning liquid in the second processing chamber 41 is emptied in about half an hour, the fifth batch of workpieces has also completed the spray cleaning operation for about half an hour. By analogy, when the fifth batch of workpieces is cleaned and the cleaning liquid is discharged into the second processing chamber 41 to reach the first preset volume, the solution that has completed heating and standing in the third processing chamber 41 is recycled, and the sixth batch of workpieces are spray cleaned. By analogy, the city water is recycled and reused. ,
