Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, specifically to the piping system of a cleaning machine. Background Technology
[0002] Solvent-based cleaning machines utilize the dissolving power of organic solvents to remove contaminants such as grease, oil, and wax from the surface of workpieces. They are widely used in machining, electronics, automotive, aerospace and other fields.
[0003] Traditional solvent-based cleaning machines typically include a cleaning tank and a solvent circulation spray system.
[0004] Traditional solvent-based cleaning machines, when handling workpieces with a large amount of stubborn or high-temperature grease (such as rust inhibitors, cutting oils, and lubricating grease), rely on a solvent circulation spray system to clean the large amount of grease on the workpiece, which is not conducive to ensuring the proper removal of grease from the workpiece.
[0005] Currently, there is a lack of pre-steam degreasing pipeline systems that can dissolve greases with solvent vapor and pre-treat greases with steam. Utility Model Content
[0006] This invention provides a pre-steam degreasing pipeline system to solve at least one of the above-mentioned technical problems.
[0007] A pre-vapor degreasing pipeline system includes a working chamber, characterized in that it includes a vacuum pipeline, wherein a first pneumatic valve, a drying condenser, a second pneumatic valve, and a vacuum pump assembly are sequentially installed on the vacuum pipeline from the side adjacent to the working chamber.
[0008] It also includes a distillation vessel for heating to generate solvent vapor, the bottom of which is equipped with a heater, and the distillation vessel is connected to the working chamber via a steam delivery pipeline, on which a third pneumatic butterfly valve is installed;
[0009] The bottom of the working chamber is connected to the distillation tank via a recovery pipeline. The recovery pipeline is equipped with a fourth pneumatic butterfly valve, a circulation pump, and a fifth pneumatic valve in sequence from the working chamber to the distillation tank.
[0010] This invention utilizes a pre-steam degreasing pipeline system to spray high-temperature solvent vapor onto the surface of the workpiece within the working chamber, thereby improving the cleaning effect. The grease treated by the high-temperature solvent vapor on the workpiece is collected and stored in a distillation tank via a recovery pipeline.
[0011] More preferably, a discharge pipeline is connected to the area of the recovery pipeline located between the fourth pneumatic butterfly valve and the circulation pump.
[0012] The drain pipe facilitates the removal of cleaning fluid during subsequent cleaning processes within the working chamber.
[0013] More preferably, a working chamber level gauge is installed inside the working chamber.
[0014] More preferably, a distillation tank level gauge is installed inside the distillation tank.
[0015] More preferably, the top of the distillation tank is equipped with staggered baffles.
[0016] More preferably, the baffle is inclined, and the highest point of the baffle is fixedly connected to the inner wall of the distillation tank.
[0017] More preferably, the outer wall of the distillation tank and the outer wall of the steam delivery pipeline are covered with a heat insulation layer.
[0018] More preferably, the heater is a tubular heater.
[0019] More preferably, the heater is equipped with a capillary thermostat to prevent dry burning.
[0020] More preferably, a temperature sensor is installed at the bottom of the distillation tank to monitor the temperature of the heating container.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 As shown, a pre-steam degreasing pipeline system includes a working chamber 5, a vacuum pipeline, and a first pneumatic valve, a drying condenser 3, a second pneumatic valve, and a vacuum pump group 1 installed sequentially from the side adjacent to the working chamber 5 on the vacuum pipeline; it also includes a distillation tank 15 for heating and generating solvent vapor, with a heater 16 installed at the bottom of the distillation tank 15. The heater 16 is used to heat the solvent in the distillation tank. The distillation tank 15 is connected to the working chamber 5 via a steam delivery pipeline, on which a third pneumatic butterfly valve 11 is installed; the bottom of the working chamber 5 is connected to the distillation tank 15 via a recovery pipeline, from which a fourth pneumatic butterfly valve, a circulation pump 8, and a fifth pneumatic valve are installed sequentially from the working chamber 5 to the distillation tank 15. This utility model uses a pre-steam degreasing pipeline system to spray high-temperature solvent vapor onto the surface of the workpiece in the working chamber 5, thereby improving the cleaning effect on the workpiece. The grease on the workpiece after being treated with high-temperature solvent vapor is collected and stored in the distillation tank 15 through the recovery pipeline.
[0026] The working chamber is used for cleaning workpieces. A movable door is installed in the working chamber for workpiece entry and exit. The working chamber also connects to a solvent circulation spray cleaning system. A spray connector for solvent circulation spraying is installed in the working chamber. A pre-steam degreasing pipeline system is set up independently of the solvent circulation spray cleaning system and is used to spray high-temperature solvent vapor onto the workpiece surface before the workpiece enters the conventional solvent spray cleaning stage.
[0027] A steam inlet for connecting to a steam delivery pipeline is installed at the top of the working chamber. A steam outlet for connecting to a steam delivery pipeline is installed at the top of the distillation tank.
[0028] A discharge line is connected to the recovery pipeline in the area between the fourth pneumatic butterfly valve 7 and the circulation pump 8. This discharge line facilitates the removal of the cleaning liquid during the subsequent cleaning process in the working chamber 5. A sixth pneumatic butterfly valve 13 is installed on the exhaust line. The recovery pipeline includes a vertically arranged outlet section, on which the fourth pneumatic butterfly valve is installed. The outlet section connects to the discharge line. The outlet section connects to an extension branch section, on which a circulation pump is installed. The recovery pipeline is equipped with an inlet pipe extending into the distillation tank, including a transverse pipe extending laterally into the distillation tank and a longitudinal pipe extending vertically. The lower end of the longitudinal pipe is open, and its upper end connects to the transverse pipe.
[0029] A working chamber level gauge 6 is installed inside the working chamber 5.
[0030] A distillation tank level gauge 17 is installed inside the distillation tank 15. An inlet for adding solvent is installed on the top of the distillation tank.
[0031] A staggered arrangement of baffles is installed on the top of the distillation tank 15. The baffles are inclined, and their highest points are fixedly connected to the inner wall of the distillation tank 15. The outer contour of the baffles is formed by a combination of straight segments and a superior arc segment. The superior arc segment of the baffle is fixedly connected to the inner wall of the distillation tank. The vertical projection of the straight segment of the upper baffle is directly opposite the vertical projection area of the lower baffle.
[0032] The outer wall of the distillation tank 15 and the outer wall of the steam conveying pipeline are covered with insulating cotton 12.
[0033] Heater 16 is a tubular heater.
[0034] A capillary thermostat 18 is installed on the heater 16 to prevent dry burning.
[0035] A temperature sensor 10 is installed at the bottom of the distillation tank 15 to monitor the temperature of the heating vessel.
[0036] Specific operating procedure: After the workpiece to be cleaned is pushed into the working chamber 5, the sliding door closes, the first pneumatic butterfly valve 4 and the second pneumatic butterfly valve 2 open, the third pneumatic butterfly valve 11 closes, and the fourth pneumatic butterfly valve 7 closes. The vacuum pump unit 1 starts to draw the pressure in the working chamber 5 to the design pressure. The first pneumatic butterfly valve 4 and the second pneumatic butterfly valve 2 close. At this time, the pressure in the working chamber 5 is lower than the pressure in the distillation tank 15. The third pneumatic butterfly valve 11 opens, and steam flows through the pipeline to the working chamber 5 to spray high-temperature solvent steam onto the surface of the workpiece for steam degreasing. After the set time is reached, the third pneumatic butterfly valve 11 closes, the fourth pneumatic butterfly valve 7 opens, the fifth pneumatic butterfly valve 9 opens, and the sixth pneumatic butterfly valve 13 closes. The circulation pump 8 starts to draw the liquid in the working chamber 5 back to the distillation tank 15. When the working chamber level gauge 6 has no signal, the circulation pump 8 stops, and the fourth pneumatic butterfly valve 7 closes and the fifth pneumatic butterfly valve 9 closes. After the pre-steam degreasing is completed, other cleaning procedures continue.
