Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for automobile parts production using room-temperature chemical degreasing treatment. Background Art

[0002] Degreasing is an important step in the process of automobile manufacturing and maintenance. Its main purpose is to thoroughly remove oil stains from the metal surface to improve the adhesion of the coating. This process is not achieved by pickling, but by using special industrial degreasers. Degreasing materials mainly include alkaline degreasers, acid degreasers and organic solvent degreasers. Alkaline degreasers use the chemical action of alkali to remove oil stains through a combination of saponification, emulsification, chemical dissolution and mechanical action. Organic solvent degreasers use their ability to dissolve various oil stains for degreasing. These methods together ensure the cleanliness of the surface of automobile parts, preparing for subsequent painting or treatment. After the degreasing of automobile parts is completed, the used wastewater needs to be treated.

[0003] Traditional wastewater treatment devices generally add purification agents and then filter and clean the mixed waste. However, since wastewater contains a variety of chemical wastes such as different metal ions, this traditional cleaning method cannot automatically detect the remaining content of different types of waste in the wastewater after treatment during actual use, and thus cannot ensure thorough cleaning. Furthermore, the wastewater treatment capacity of the device cannot be flexibly adjusted according to the test results, resulting in incomplete wastewater treatment. If the treatment is repeated, the filtration effect will not change because the device cannot flexibly adjust the wastewater filtration capacity, which not only affects the wastewater treatment efficiency of the device, but also has poor use effect.

[0017] The present invention has the following advantages: when in use, the purification agent is fully contacted and mixed with the wastewater to achieve full purification of the wastewater. After the chemical substances in the wastewater react with the agent, colloid and other impurities are generated. Then, the solenoid valve on the sewer pipe is opened, and the wastewater enters the filter box through the sewer pipe. The impurities precipitated in the wastewater are filtered under the action of the filter net. The wastewater then enters the purification box below through the water pipe. Under the action of the purification adsorption plate in the purification box, some impurities such as metal ions in the wastewater that do not react with the purification agent are adsorbed. Then, the wastewater enters another purification box below to filter and adsorb another kind of impurities.

[0018] The purified wastewater enters the detection box and flows through the purification detection plate. The purification detection plate has the same purification and adsorption function as the purification adsorption plate in the purification box. After the wastewater flows through the purification detection plate, if the wastewater is not completely purified by the purification method above, a certain amount of impurities will be adsorbed on the detection plate at this time, and the weight of the purification detection plate will increase and then squeeze the elastic part. The movable rod will move down a certain distance relative to the detection box. At this time, the transmission rod will contact the valve column, and the valve column will move laterally into the sensing block under the force of the transmission rod. The valve mouth will correspond to the through groove. At this time, the sensing block is in an open state. In this process, the greater the amount of waste detected by the purification detection board, the more sensing blocks will be opened. If the filtration and purification above are thorough, no sensing block will be opened. After the wastewater passes through the sensing rod after detection, the sensing rod will rotate and contact the sensor. At this time, the wastewater filtration and detection are completed, and the sensor controls the induction air pump to start, and the induction air pump is inflated. The gas passes through the opened sensing block. Finally, it enters the installation shell. The increased pressure in the installation shell drives the guide rod to move downward, and the purification adsorption plate moves down to the bottom of the purification box. This process increases the number of purification adsorption plates in the purification box, and the single purification effect of the device will be better. At the same time, the gas in the installation shell will enter the air guide column through the diversion groove and finally enter the installation cylinder. The increased pressure in the installation cylinder will drive the guide nozzle at the end of the piston rod to move. In the initial state, the guide nozzle is located on one side of the partition. If the detected wastewater is purified, the guide nozzle will not move, and the completely purified water will flow to one side of the partition for collection and use. If the purification is not clean, the guide nozzle will move to the other side of the partition, and under the action of the water pump, the incompletely purified wastewater will be sent into the purification box through the reflux pipe. Since the number of purification adsorption plates is increased in the purification box, the purification effect can be better achieved. This method can not only ensure that the device purifies the wastewater more thoroughly, but also can flexibly adjust the purification capacity according to the waste content in the wastewater, thereby improving the purification efficiency.

[0045] The actual principle of the use of this device is: when in use, the wastewater used for degreasing of automobile parts is placed in the mixing drum 6, and then the driving motor 7 is started to drive the rotating column 48 to rotate. Under the action of the stirring blade 49, the wastewater is stirred, and the purification agent is added at the same time. During the stirring process, the purification agent and the wastewater are fully contacted and mixed to achieve full purification of the wastewater. The chemical substances in the wastewater react with the agent to produce impurities such as colloids, and then the solenoid valve on the downpipe 9 is opened, and the wastewater enters the filter box 8 through the downpipe 9. Under the action of the filter screen 50, the impurities precipitated in the wastewater are filtered. The wastewater then enters the purification box 10 below through the water pipe 12. Under the action of the purification adsorption plate 54 in the purification box 10, some impurities such as metal ions in the wastewater that do not react with the purification agent are adsorbed, and then the wastewater enters another purification box 10 below to filter and adsorb another kind of impurities;

[0046] The purified wastewater enters the detection box 16, and the wastewater flows through the purification detection plate 31. The purification detection plate 31 has the same purification and adsorption function as the purification adsorption plate 54 in the purification box 10. After the wastewater flows through the purification detection plate 31, if the wastewater is not completely purified by the purification method above, a certain amount of impurities will be adsorbed on the detection plate at this time, and the weight of the purification detection plate 31 will increase and then squeeze the elastic member 34. The movable rod 32 will move down a certain distance relative to the detection box 16. At this time, the transmission rod 57 will contact the valve column 33. The valve column 33 will move laterally into the sensor block 25 under the force of the transmission rod 57. The valve port 56 will correspond to the through groove 43. At this time, the sensor block 25 is in an open state. In this process, the greater the amount of waste detected by the purification detection plate 31, the more the number of opened sensor blocks 25. If the filtration and purification above is thorough, no sensor block 25 will be opened. After the wastewater passes through the sensor rod 42 after detection, the sensor rod 42 will rotate and contact the sensor 44. At this time, it means that the wastewater filtration detection is completed, and the sensor 44 controls The control induction air pump 2 is started, the induction air pump 2 is inflated, and the gas finally enters the installation shell 15 through the opened induction block 25. The pressure increase in the installation shell 15 drives the guide rod 53 to move downward, and the purification adsorption plate 54 moves down to the bottom of the purification box 10. This process increases the number of purification adsorption plates 54 in the purification box 10, and the single purification effect of the device will be better. At the same time, the gas in the installation shell 15 will enter the air guide column 20 through the diverter groove 26, and finally enter the installation cylinder 3. The pressure increase in the installation cylinder 3 will drive The guide nozzle 40 at the end of the piston rod 37 moves. In the initial state, the guide nozzle 40 is located on one side of the partition 39. If the detected wastewater is purified, the guide nozzle 40 does not move, and the completely purified water flows to the side of the partition 39 for collection and standby use. If the purification is not thorough, the guide nozzle 40 moves to the other side of the partition 39, and under the action of the water pump 23, the incompletely purified wastewater is sent into the purification box 10 through the reflux pipe 13. Since the number of purification adsorption plates 54 is increased in the purification box 10, the purification effect can be better achieved.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
