Description

[Technical field]

[0001] The invention belongs to the technical field of steam degreasing equipment, and in particular relates to a steam degreasing system and method capable of self-cleaning cleaning agents. [Background technology]

[0002] In the field of metal surface treatment technology, metal surface degreasing is a key step in the entire surface treatment process. The effect of metal surface degreasing plays a vital role in the smooth execution of subsequent processes and ensuring the final quality and service life of the product.

[0003] At present, organic solvent degreasing is one of the more commonly used methods in metal surface degreasing operations, including immersion, spraying and steam washing. However, practice has found that these traditional organic solvent degreasing methods have the problem of incomplete degreasing effect. The residual oil will form a thin layer of pollution on the metal surface. This pollution layer will interfere with the smooth progress of the next process. For example, it may cause the adhesion of the subsequent coating to decrease, the uniformity and density of the electroplating layer to deteriorate, and in the long run, the pollution will seriously affect the quality stability and service life of the entire product. With the continuous improvement of industrial production's requirements for the quality of metal products, this problem of incomplete degreasing has become increasingly prominent. There is an urgent need for an innovative technical solution that can effectively solve the problem of incomplete organic solvent degreasing on metal surfaces to meet the urgent needs of modern industrial production for high-quality metal surface treatment.

[0004] In a Chinese utility model patent with application number 201520340788.0 and application date May 25, 2015, a degreasing device for metal surface is disclosed, which includes a first degreasing tank, a second degreasing tank and a third degreasing tank connected in sequence. The first degreasing tank and the second degreasing tank are filled with organic solvents, the first degreasing tank has a first heating device and ultrasonic waves at the bottom, and the third degreasing tank has a second heating device at the bottom. The tops of the three degreasing tanks are all provided with cooling pipes, and the top of the first degreasing tank is provided with a spray device below the cooling pipe. The second degreasing tank is equipped with an air dryer workbench and a cooling device outside, and the metal workpiece to be processed is moved by a hoist. The first heating device and ultrasonic waves help the organic solvent to remove oil stains on the metal workpiece in the first degreasing tank, and the second degreasing tank further removes oil. The heating device at the bottom of the third degreasing tank may be used for subsequent processing or to maintain a certain temperature environment. The cooling pipe is used to control the temperature in each degreasing tank to prevent excessive volatilization of the organic solvent. The spray device of the first degreasing tank removes oil stains on the metal surface by spraying organic solvents. The air dryer workbench outside the second degreasing tank is used for air drying of the workpieces. The cooling device may be used to assist in controlling the temperature or to make the workpiece reach a suitable processing state. The elevator realizes the position transfer of the workpiece between the tanks, thereby completing the entire degreasing process and improving the degreasing effect of the metal surface.

[0005] However, the degreasing device for metal surfaces uses a spraying method for cleaning, which makes it difficult to clean the inner holes, deep holes and inner cavity surfaces of porous parts and parts with complex geometric structures. Moreover, the long spraying time can easily cause the parts to rust, resulting in poor cleaning effect. Secondly, the organic solvent cleaning agent is contaminated after repeated use in multiple tanks, and needs to be replaced and shipped out by a qualified third party for treatment, which has high use costs. In addition, since there is no condensation return device for the heating and cooling exhaust in production, a large amount of organic solvent cleaning agent steam is discharged with VOC waste gas or overflows the workshop, which will pollute the workshop environment. And endanger the occupational health of operators. The present invention provides a steam degreasing system with a self-cleaning cleaning agent to solve the technical problems in the prior art that when parts are degreasing, parts are prone to rust, the cleaning effect is poor, the cost of organic solvent cleaning agent treatment is high, and the overflow of organic solvent cleaning agent steam endangers the health and safety of operators. The present invention also provides a steam degreasing method with a self-cleaning cleaning agent to solve the above technical problems.

[0006] The technical solution of a steam degreasing system capable of self-cleaning detergent provided by the present invention is:

[0007] A steam degreasing system for self-cleaning cleaning agents comprises a degreasing tank and a heating system, a steam bath tank is provided at the bottom of the degreasing tank, the steam bath tank is used to hold the cleaning agent, a condensation recovery baffle is provided in the middle of the degreasing tank, a steam condensation zone is located above the condensation recovery baffle, a steam cleaning zone is located below the condensation recovery baffle, the condensate recovery baffle is used to recover the condensed cleaning agent liquid flowing down the tank wall from the steam condensation zone, a cleaning agent condensation recovery system is connected to the side wall of the steam condensation zone, the cleaning agent condensation system comprises a cleaning agent reflux pipe, the cleaning agent reflux pipe is connected to the condensate recovery baffle, a cleaning agent reflux control valve is provided on the cleaning agent reflux pipe, and the cleaning agent reflux pipe is connected to the steam bath tank.

[0008] Furthermore, the steam condensation zone comprises an inner groove wall of the condensation zone, an outer groove wall of the condensation zone is arranged outside the inner groove wall of the condensation zone, and condensate is passed between the inner groove wall of the condensation zone and the outer groove wall of the condensation zone.

[0009] Furthermore, the cleaning agent condensation recovery system includes a condensation tank, a steam inlet pipe, a first condensate inlet pipe and a second condensate inlet pipe. The condensation tank includes a condensate flow path and a steam flow path. The first condensate inlet pipe is used to connect the inner tank wall of the condensation zone and the outer tank wall of the condensation zone. The second condensate inlet pipe is used to connect the condensate flow path. The steam inlet pipe is used to connect the inside of the inner tank wall of the condensation zone and the inlet end of the steam flow path. The cleaning agent reflux pipe is connected to the outlet end of the steam flow path.

[0010] Furthermore, the cleaning agent condensation recovery system also includes an exhaust pipe and a condensate reflux pipe.

[0011] Furthermore, the cleaning agent reflux pipe is connected to the steam bath tank through the cleaning agent recovery tank, a steam bath tank recovery pipe is connected between the cleaning agent recovery tank and the steam bath tank, and a steam bath tank recovery control valve is provided on the steam bath tank recovery pipe.

[0012] Furthermore, a slot side exhaust device is provided at a position close to the top on the side wall of the steam condensation zone.

[0013] Furthermore, a parts support frame is provided above the steam bath tank for placing parts that need to be steam cleaned.

[0014] The beneficial effects are:

[0015] (1) A steam bath is set at the bottom of the degreasing tank to hold the cleaning agent, and a condensation recovery partition is set in the middle of the degreasing tank to divide the steam condensation area and the steam cleaning area. At the same time, a cleaning agent condensation recovery system is equipped to achieve the recycling of cleaning agents, reduce the waste of cleaning agents, reduce the cost of use, and also benefit environmental protection. Moreover, this structural design makes the steam degreasing process more efficient, improves the degreasing effect and work efficiency, because the steam can fully play a cleaning role in the cleaning area, and the condensation recovery partition can timely recover the condensed cleaning agent, ensuring the continuous and stable operation of the system.

[0016] (2) The steam condensation area is provided with an inner trough wall and an outer trough wall, and condensate is passed between them, which can speed up the condensation of steam and improve the condensation efficiency. The efficient condensation process helps to recover the cleaning agent steam in time and reduce the diffusion of steam in the working area, which not only further improves the recycling rate of the cleaning agent, but also improves the working environment and reduces the potential impact of steam on operators and surrounding equipment, such as reducing problems such as obstructed vision and dampness of equipment caused by steam diffusion.

[0017] (3) The cleaning agent condensation recovery system includes a complex and sophisticated structural design such as a condenser, a steam inlet pipe, a first condensate inlet pipe, and a second condensate inlet pipe, making the cleaning agent condensation recovery process more scientific and efficient. The steam inlet pipe can accurately introduce steam into the steam flow path of the condenser, and cooperate with the condensate entering through the first condensate inlet pipe and other condensates introduced by the second condensate inlet pipe to achieve full condensation and recovery of the cleaning agent in the steam. The cleaning agent return pipe is connected to the outlet end of the steam flow path to ensure that the recovered cleaning agent can be smoothly returned to the steam bath for reuse, which greatly improves the resource utilization and economic benefits of the entire system, while ensuring the stable operation and continuous and efficient cleaning capabilities of the steam degreasing system.

[0018] (4) An exhaust pipe and a condensate return pipe are added to the cleaning agent condensation recovery system. The exhaust pipe can promptly discharge the non-condensable gas generated in the system to ensure the smooth progress of the condensation process and avoid the accumulation of non-condensable gas in the system that affects the condensation effect and system pressure balance. The condensate return pipe further optimizes the condensate recovery path, ensuring that all recyclable condensate can be effectively collected and reused, improving the recovery rate of the cleaning agent, reducing the loss of the cleaning agent and the emission to the environment. At the same time, it also helps to maintain a stable operating environment within the system and reduce the failures and pollution problems that may be caused by residual condensate or improper discharge.

[0019] (5) The cleaning agent reflux pipe is connected to the steam bath tank through the cleaning agent recovery tank, and a steam bath tank recovery pipe and a steam bath tank recovery control valve are provided. The cleaning agent recovery tank can play a role in buffering and preliminary precipitation of impurities, preventing impurities from directly entering the steam bath tank and affecting the cleaning agent quality and subsequent cleaning effect. The steam bath tank recovery pipe and control valve facilitate flexible recovery and replenishment control of the cleaning agent in the steam bath tank, and adjust the liquid level and purity of the cleaning agent in the steam bath tank according to actual use conditions, ensuring that the steam degreasing system is always in the best working state, extending the service life of the cleaning agent, and improving the cleaning quality and system reliability.

[0020] (6) Installing trough exhaust equipment near the top of the side wall of the steam condensation area can timely and effectively discharge the small amount of residual steam and odorous gas generated during the steam degreasing process, further improve the air quality in the workplace, and provide operators with a more comfortable and healthy working environment. At the same time, good ventilation conditions help maintain the pressure stability in the system and avoid abnormal pressure caused by steam accumulation, thereby ensuring the safe and stable operation of the entire steam degreasing system and reducing the potential safety hazards caused by gas accumulation, such as explosion risks.

[0021] (7) A parts support rack is set above the steam bath to provide a stable and suitable placement for the parts that need to be steam cleaned, ensuring that the parts can fully contact the steam, so that the steam can evenly act on the oily parts on the surface of the parts, improving the cleaning effect and cleaning efficiency. In addition, the special parts support rack design can prevent the parts from directly contacting the bottom of the degreasing tank or other components, reduce the risk of collision and scratching of the parts during the cleaning process, ensure the integrity and surface quality of the parts, and improve the product yield. It is particularly suitable for cleaning operations of precision parts with high surface quality requirements.

[0022] The technical solution of a steam degreasing method with a self-cleaning detergent provided by the present invention is:

[0023] A steam degreasing method for a self-cleaning detergent: when parts need to be cleaned, open the cover of a steam bath, hoist the workpiece into the steam cleaning area in the steam bath, and then close the cover of the steam bath. Then, according to the size of the parts to be cleaned, select the cleaning temperature and cleaning time, start the heating system and the detergent condensation recovery system, heat the detergent at the bottom of the solvent tank to a certain temperature, vaporize the detergent into detergent steam, dissolve the oil attached to the surface of the parts and take it away, enter the steam condensation area, and the detergent steam with oil will liquefy after contacting the tank wall of the steam condensation area, flow along the steam bath tank wall to the condensate recovery partition, and then flow to the bottom of the steam cleaning area or the organic solution recovery tank through a reflux pipe.

[0024] Furthermore, when the cleaning time of the degreased parts reaches the set value, the heating system is turned off and the condensation recovery system continues to run for a fixed period of time to ensure that all steam in the steam bath is condensed and recovered. The condensation recovery system is then turned off and the parts are allowed to cool naturally. The temperature inside the steam bath is detected by a temperature sensor. When the temperature inside the steam bath drops to the set value, an audible and visual alarm is used to remind you. Then, the exhaust equipment on the side of the bath and the cover of the steam bath are opened to take out the cleaned parts from the top of the steam bath.

[0025] Furthermore, samples are taken from the sampling port regularly. When the oil concentration in the cleaning agent reaches the warning value, the heating system and the cleaning agent condensation recovery system are started, and the cleaning agent is vaporized into cleaning agent steam. The cleaning agent steam enters the steam condensation area, liquefies after contacting the tank wall of the steam condensation area, flows along the wall of the steam bath tank to the condensate recovery partition, and then flows to the bottom of the steam cleaning area or the organic solution recovery tank through the reflux pipe, and the sludge is cleaned from the inspection door.

[0026] A steam degreasing method for a self-cleaning detergent has the beneficial effects of the above-mentioned steam degreasing system for a self-cleaning detergent.

The condensation tank includes a condensate flow path and a steam flow path. The steam bath condensate inlet pipe is used to pass condensate between the inner groove wall of the condensation zone and the outer groove wall of the condensation zone. The condensate inlet pipe of the condensation tank is connected to the condensate flow path. The steam air inlet pipe is used to connect the inner groove wall of the condensation zone and the inlet end of the steam flow path. The cleaning agent reflux pipe is connected to the outlet end of the steam flow path. A condensation zone support frame is also arranged outside the outer groove wall of the condensation zone, and a condensation zone thermal insulation layer is arranged outside the condensation zone support frame. In this embodiment, the inner groove wall of the condensation zone, the outer groove wall of the condensation zone and the condensation zone support frame are all made of stainless steel, thereby effectively avoiding corrosion caused by the cleaning agent. In this embodiment, the cleaning agent reflux pipe is connected to the steam bath tank through the cleaning agent recovery tank, and a steam bath tank recovery pipe is connected between the cleaning agent recovery tank and the steam bath tank, and a steam bath tank recovery control valve is provided on the steam bath tank recovery pipe.

[0037] As shown in the figure, the steam cleaning area includes a cleaning area tank wall, a cleaning area support frame is arranged outside the cleaning area tank wall, a cleaning area thermal insulation layer is arranged outside the cleaning area support frame, a cleaning area thermal insulation layer support frame is arranged outside the cleaning area thermal insulation layer, a solvent tank is arranged at the bottom of the steam cleaning area, and a parts support frame is arranged above the solvent tank for placing parts that need to be steam cleaned.

[0040] A drain port is provided at the bottom of the solvent tank. When the cleaning agent with oily dirt needs to be separated, it is separated into the recovery tank, while the oily impurities and other sludge are left at the bottom of the steam bath tank, and then the sludge is cleaned from the drain port. The steam degreasing system of the self-cleaning cleaning agent also includes an electrical control cabinet, which includes a control cabinet, a temperature sensor, a temperature control meter, and cables. In this embodiment, the cleaning agent is an organic solvent.

[0041] The working process of the steam degreasing system with self-cleaning detergent is as follows:

[0042] When parts need to be cleaned, open the cover of the steam bath, lift the workpiece into the steam cleaning area of ​​the steam bath, place it on the part support frame, and then close the cover. Then, according to the size of the parts to be cleaned, select the set cleaning temperature and cleaning time, start the heating system, heat the cleaning agent at the bottom of the steam bath to a certain temperature to vaporize it, and the cleaning agent vapor will adhere to the surface of the parts to dissolve and take away the oil on the surface of the parts, and then enter the steam condensation area. After contacting the wall of the steam condensation area filled with cold water, the condensed liquefied droplets flow along the wall of the steam bath to the condensate recovery partition, and then flow through the reflux pipe to the bottom of the steam cleaning area or the organic solution recovery tank. The above steps can be repeated many times, so that the cleaning agent repeatedly undergoes evaporation and vaporization, adheres to and dissolves the oil, and carries the oil away, thereby achieving the purpose of effectively removing oil and cleaning the surface of the workpiece.

[0043] When the cleaning time of the parts that need to be reversed degreased reaches the set value, turn off the heating system and enable the condensation recovery system to continue running for a fixed period of time to ensure that all steam in the steam bath is condensed and recovered. Then turn off the condensation recovery system and wait for the parts to cool naturally. The temperature inside the degreasing tank is detected by the temperature sensor.

[0044] In addition, when the equipment is in the shutdown state, samples are taken from the sampling port regularly and the machine solvent cleaning agent is tested. When the oil concentration in the machine solvent cleaning agent reaches the warning value, the heating system is started, and the cleaning agent is evaporated by utilizing the different boiling points of the cleaning agent and the oil. Then the flow direction of the condensation reflux pipeline is adjusted and switched to separate the clean cleaning agent into the recovery tank, while the oil impurities and other sludge are left at the bottom of the steam bath. Then the sludge is cleaned from the drain port, and the clean cleaning agent is returned to the steam bath for continued use.
