Description

Technical Field

[0001] This utility model belongs to the technical field of heat treatment workpiece cleaning equipment, specifically relating to a through-type vacuum cleaning machine. Background Technology

[0002] Before undergoing heat treatments such as carburizing, quenching, and nitriding, mechanical parts need to be cleaned. Ordinary cleaning machines or ultrasonic vacuum cleaning machines are required to remove surface oil and other contaminants to prevent uneven carburizing and other heat treatment problems after the parts have been treated.

[0003] In a conventional cleaning machine, materials enter the spray chamber through the feed door, descend to the alkaline water tank for immersion via a lifting mechanism, and after immersion, are lifted back to the spray chamber for spraying, then to the drying chamber for drying. After drying, the materials exit through the discharge door into the tempering furnace for tempering. This cleaning machine requires a lifting mechanism to complete the immersion washing of the workpieces, resulting in multiple processes and a long processing time.

[0004] An ultrasonic vacuum cleaner includes a cleaning chamber, a vacuum system, and a cleaning system. A cleaning cavity is formed inside the cleaning chamber. The vacuum system evacuates the cleaning cavity, and the cleaning system delivers cleaning fluid into the cleaning cavity to spray the workpiece inside, thereby achieving ultrasonic cleaning of the workpiece inside the cleaning chamber. However, current vacuum cleaning chambers usually use a single door for entry and exit, which cannot be used for continuous heat treatment production lines. Utility Model Content

[0027] Example 1

[0028] A type of through-type vacuum cleaner, such as Figures 1-3 As shown, it includes: a cleaning chamber 1, a vacuum system, a spray system, and a conveying system 10. The cleaning chamber 1 is a through structure, with a feed door 2 at one end and a discharge door 3 at the other end. A drain outlet 20 is located at the bottom of the cleaning chamber 1, and the air extraction port is also connected to a first back pressure port.

[0029] The vacuum system includes: a vacuum chamber 4, a vacuum pump 15, and a vacuum connecting pipe; the top of the cleaning chamber 1 is provided with an air extraction port 5, the vacuum connecting pipe connects the vacuum chamber 4 and the air extraction port 5, and is provided with a third solenoid valve; a second back pressure port is provided on the vacuum connecting pipe, and the vacuum pump 15 evacuates the vacuum chamber 4.

[0030] The spray system includes: a water tank 16, a spray pipe 6, and a spray head; the water tank 16 is located at the top of the cleaning chamber 1, and the water inlet of the spray pipe 6 is inserted into the water tank 16 and located near the bottom of the water tank 16; the spray pipe 6 is equipped with a booster pump 19 and a control valve 9, and its outlet is connected to the spray head located inside the cleaning chamber 1.

[0031] The conveying system 10 includes a conveyor belt and a conveyor motor; the conveyor belt is disposed on the bottom surface inside the cleaning chamber 1, and the conveyor motor is disposed on the outside of the side wall of the cleaning chamber 1, with its power output end connected to the drive wheel of the conveyor belt.

[0032] The working process of this utility model is as follows: before cleaning the workpiece, start the vacuum pump 15 to create a negative pressure in the vacuum chamber 4, and at the same time close the first solenoid valve, the second solenoid valve, and the third solenoid valve.

[0033] When cleaning the workpiece, the feed door 2 is opened, and the external system 25 feeds in the workpiece to be cleaned. The external system 25 can be a robotic arm or a robot, depending on the needs. After the workpiece enters the cleaning chamber 1 through the feed door 2, the conveyor motor is started, so that the workpiece to be cleaned is transported to the cleaning station by the conveyor belt. At this time, the feed door 2 is closed.

[0034] Subsequently, control valve 9 opens to a preset opening to control the flow rate of the cleaning fluid. The cleaning fluid in the water tank 16 is pressurized by the booster pump 19 and sprayed out through the spray pipe 6 into the spray head inside the cleaning chamber 1 to spray and clean the workpiece. At this time, since the feed door 2, the discharge door 3, and the first solenoid valve are all in the closed state, a water-sealed closed cavity is formed, so the cleaning fluid gradually accumulates and submerges the workpiece to be cleaned. Based on this setting, this utility model eliminates the need for an immersion tank, and there is no need to lower the workpiece into the immersion tank for immersion, thus eliminating the need for a lifting mechanism.

[0035] Then, the booster pump 19 is turned off, and the third solenoid valve is opened to connect the vacuum chamber 4 and the cleaning chamber 1 through the vacuum connection pipe. Since the vacuum chamber 4 is under negative pressure, the opening of the third solenoid valve allows the air pressure in the vacuum chamber 4 and the cleaning chamber 1 to quickly balance, thereby causing the air pressure in the cleaning chamber 1 to gradually decrease. This rapid decrease causes the cleaning fluid immersing the workpiece to quickly generate a large number of bubbles. These bubbles will wash over the workpiece, thus significantly improving the immersion cleaning effect.

[0036] After immersion cleaning, open the first and second solenoid valves and close the third solenoid valve. The cleaning solution used for immersion cleaning is discharged from the drain outlet 20. The discharged cleaning solution can be connected to the subsequent wastewater treatment device, and after wastewater treatment, it flows back into the water tank 16. At the same time, external air enters the cleaning chamber 1 through the first backpressure port 21 and the second backpressure port 22, causing the cleaning chamber 1 to return to its chamber pressure. After the cleaning solution used for immersion cleaning has been drained, restart the booster pump 19 to pump the cleaning solution into the spray head again for spray cleaning of the workpiece. The waste liquid from the spray cleaning is discharged from the drain outlet to the subsequent wastewater treatment device. After the cleaning chamber 1 returns to its chamber pressure, close the second solenoid valve.

[0037] After the spray cleaning is completed, close the first solenoid valve and open the third electronic valve and vacuum pump 15 to vacuum dry the cleaning chamber 1. After vacuum drying is completed, open the second solenoid valve and close the third electronic valve. After the cleaning chamber 1 returns to its original pressure, close the second solenoid valve.

[0038] Finally, the discharge gate 3 is opened and the conveyor motor is started, so that the cleaned workpiece is sent out of the cleaning chamber 1 by the conveyor belt and taken away by another peripheral system.

[0039] The improved through-type vacuum cleaner of this utility model is a combination of a conventional cleaner and a vacuum cleaner, and can be well applied to continuous heat treatment production lines.

[0040] Example 2

[0041] Based on the through-type vacuum cleaner of Example 1, such as Figure 1 As shown, the spray pipe 6 is connected to multiple top pipes 7 through the top main pipe 17 and to multiple vertical pipes 8 through the middle main pipe 18; the top pipes 7 are located near the top of the cleaning chamber 1, and the vertical pipes 8 are set on the inner walls of both sides along the through axis; spray heads are evenly arranged on the top pipes 7 and vertical pipes 8 facing the material position.

[0042] This setup connects the spray pipe 6 to the top pipe 7 and the vertical pipe 8 respectively, thereby providing multi-directional spraying from the top and sides to the workpiece to be cleaned. Compared with the traditional top spraying method, this utility model has a larger spraying range and better cleaning spraying effect.

[0043] Example 3

[0044] like Figures 3-4 As shown, based on the through-type vacuum cleaner of Embodiment 1, the vacuum system further includes a drainage system, which includes a storage chamber 24 and a drainage pump 23. The storage chamber 24 is connected to the vacuum chamber 4, and the drain outlet 20 of the cleaning chamber 1 is connected to the storage chamber 24. The bottom of the storage chamber 24 is connected to the waste liquid treatment system behind it through a drainage pipe, and a drainage pump 23 is installed on the drainage pipe.

[0045] Since the cleaning chamber 1 is generally humid during vacuuming, the humid air easily forms liquid accumulation in the vacuum chamber 4. When there is a large amount of liquid accumulation, it overflows into the storage chamber. The liquid accumulation in the vacuum chamber 4 can be discharged through the drain pipe 14 to the external waste liquid treatment system for treatment by starting the drain pump. The treated cleaning fluid can then be added to the water tank 16.

[0046] Example 4

[0047] Based on the through-type vacuum cleaner of Example 1, such as Figures 5-6 As shown, the feeding door 2 and the discharging door 3 have the same structure, both including: door panel 26 and lifting device; the lifting device includes: door frame 11 and lifting motor 12; the door panel is set inside the door frame 11 and slides up and down along the door frame 11; the lifting motor 12 drives the sprocket 13 to rotate, and the sprocket 13 is connected to a corresponding cable, one end of the cable is connected to the top of the door panel, and the other end is located in the storage groove.

[0048] When the door needs to be opened, the motor 12 drives the sprocket 13 to rotate, which in turn drives the cable upward, causing the door panel to move upward along the door frame 11, thus realizing the opening action. Conversely, the sprocket moves downward to close the door. A sliding water seal is achieved between the door panel and the door frame 11 by wrapping the sealing gasket around the edge of the door panel. This structure enables control of the door panel's opening and closing, achieving automated remote management and saving labor.

[0049] Example 5

[0050] Based on the through-type vacuum cleaner of Example 1, such as Figure 1 As shown, a pressure gauge is installed on the outer wall of the vacuum chamber 4 to display the vacuum level inside the vacuum chamber 4.

[0051] The vacuum chamber 4 is equipped with a pressure gauge to monitor the working pressure status of the vacuum pump 15 in real time, which facilitates control.

[0052] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
