With the increasing frequency of testing work, glassware cleaning has become a heavy and time-consuming task. Manual cleaning is not only inefficient but also makes it difficult to guarantee consistency and thoroughness, and may introduce the risk of cross-contamination due to human error. Furthermore, for glassware containing hazardous chemicals, manual cleaning poses certain safety hazards to personnel. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic cleaning device for aviation kerosene detector dishes, which can realize the mechanical automation of cleaning aviation kerosene detector dishes.

[0005] To solve the above-mentioned technical problems, the technical solution of the automatic cleaning device for aviation kerosene detector dishes of this utility model is as follows:

[0006] The system includes a cleaning operation chamber 10, a rinsing solution container 20, and a detergent container 30. A screen tray 11 is fixedly installed inside the cleaning operation chamber 10, and multiple nozzles 12 are fixedly arranged on the screen tray 11. The nozzles 12 are connected to the outlet of the cleaning pump 5. One end of the cleaning operation chamber 10 is connected to a hot air blower 2, and the other end is connected to an exhaust duct. A negative pressure generator 3 and a filter 4 are installed on the exhaust duct. The rinsing solution container 20 is connected to the cleaning operation chamber 10 through a rinsing waste liquid discharge pipe. The device 20 is connected to the water source 1 through the inlet pipe 41, and the outlet of the rinsing liquid container 20 is connected to the inlet of the cleaning pump 5 through the rinsing liquid delivery pipe; a rinsing liquid control valve 22 is installed on the rinsing liquid delivery pipe; the detergent container 30 is connected to the cleaning operation chamber 10 through the washing waste liquid discharge pipe; the detergent container 30 is connected to the water source 1 through another inlet pipe 41, and the outlet of the detergent container 30 is connected to the inlet of the cleaning pump 5 through the washing liquid delivery pipe; a washing liquid control valve 32 is installed on the washing liquid delivery pipe.

[0007] In another embodiment, the nozzle 12 is connected to the outlet end of the nozzle connecting pipe 50 via a pipe, and the inlet end of the nozzle connecting pipe 50 is connected to the outlet of the cleaning pump 5 via a media conveying pipe 51; a media conveying control valve 52 is provided on the media conveying pipe 51.

[0008] In another embodiment, the inlet end of the nozzle connecting pipe 50 is connected to the outlet end of the compressed air pipe 61, and the inlet end of the compressed air pipe 61 is connected to the compressor 6; a compressed air control valve 62 is provided on the compressed air pipe 61.

[0009] In another embodiment, the outlet of the detergent container 30 is connected to the inlet end of the drain pipe 71 via a first discharge pipe 33; a detergent discharge control valve 34 is provided on the first discharge pipe 33.

[0010] In another embodiment, the outlet of the rinsing liquid container 20 is connected to the inlet end of the drain pipe 71 via a second discharge pipe 23; a rinsing liquid discharge control valve 24 is provided on the second discharge pipe 23.

Under the combined action of high temperature and pressure, it can completely remove jet fuel and contaminants generated by jet fuel detection in a short time, restoring the jet fuel detector dish to its clean and original state.

[0018] This invention can effectively improve the efficiency, safety, and accuracy of utensil cleaning.

[0019] This invention standardizes the cleaning process by controlling the spraying time and temperature, avoiding the subjectivity and randomness of manual operation. The ability to perform multi-batch cleaning significantly improves efficiency, making it especially suitable for laboratories with high testing frequency.

[0020] This invention controls the spray pressure to allow the cleaning fluid to penetrate deep into internal crevices (such as ground joints and piston grooves) to remove jet fuel residue that is difficult to reach manually, thus achieving deep cleaning of complex-structured vessels.

[0021] This invention enables gradient rinsing, such as first using a special detergent to remove grease, and then rinsing in steps with deionized water / organic solvents, which can reduce chemical residues and cross-contamination, and avoid the problems of detergent residue or incomplete rinsing in traditional manual cleaning.

[0022] This invention uses a cleaning operation chamber as a closed cleaning chamber, which can prevent external contamination and is especially suitable for high-sensitivity detection projects (such as the analysis of benzene series compounds in aviation kerosene), avoiding the introduction of environmental particles or fingerprint grease during manual operation.

[0023] This invention enables fully enclosed cleaning, eliminating the need for operators to directly contact highly corrosive cleaning solutions (such as chromic acid) or organic solvents (such as carbon tetrachloride), thereby reducing safety risks such as poisoning and burns.

[0053] The rinsing waste liquid discharge pipe is equipped with a rinsing liquid filter 25 and a one-way valve so that the medium flow direction of the rinsing waste liquid discharge pipe is from the self-cleaning operation chamber 10 to the rinsing liquid container 20.

[0054] A detergent filter 35 and another check valve are installed on the wastewater discharge pipe so that the medium flow direction of the wastewater discharge pipe is from the self-cleaning operation chamber 10 to the detergent container 30.

[0055] Heaters 21 and 31 are respectively installed at the bottom of the rinsing liquid container 20 and the detergent container 30;

[0056] The rinsing solution container 20 is connected to the water source 1 through the inlet pipe 41, and the outlet of the rinsing solution container 20 is connected to the inlet of the cleaning pump 5 through the rinsing solution delivery pipe; a rinsing solution control valve 22 is installed on the rinsing solution delivery pipe.

[0057] The detergent container 30 is connected to the water source 1 through another inlet pipe 41, and the outlet of the detergent container 30 is connected to the inlet of the cleaning pump 5 through the detergent delivery pipe; a detergent control valve 32 is installed on the detergent delivery pipe; during use, only one of the rinsing liquid control valve 22 and the detergent control valve 32 is open.

[0058] The outlet of the cleaning pump 5 is connected to the inlet end of the nozzle connecting pipe 50 via the medium conveying pipe 51. The outlet end of the nozzle connecting pipe 50 is connected to each nozzle 12 via pipes. A medium conveying control valve 52 is installed on the medium conveying pipe 51.

During use, only one of the detergent discharge control valve 34 and the rinse fluid discharge control valve 24 is open.

[0061] The working principle of this utility model is as follows:

[0062] Water source 1 delivers fresh water to rinse solution container 20 and detergent container 30 respectively;

[0063] The fresh water dilutes the detergent in the detergent container 30 into a washing liquid, and the heater 31 heats the washing liquid to about 85°C.

[0064] Heater 21 heats the fresh water (i.e., rinsing solution) in rinse solution container 20 to about 85°C;

[0065] The washing liquid control valve 32 and the media delivery control valve 52 are opened. The cleaning pump 5 delivers the hot washing liquid in the detergent container 30 to each nozzle 12 through the media delivery pipeline 51 and the delivery nozzle connection pipeline 50. The nozzles 12 spray the hot washing liquid onto the upside-down vessel 40 to be cleaned, thereby washing the vessel 40. The washing waste liquid generated by washing enters the washing waste liquid discharge pipeline through the bottom of the cleaning operation chamber 10. After being filtered by the detergent filter 35, the washing waste liquid flows back to the detergent container 30.

[0066] After the washing operation is completed, the washing liquid control valve 32 is closed, and then the rinsing liquid control valve 22 is opened. The cleaning pump 5 delivers the hot rinsing liquid in the rinsing liquid container 20 to each nozzle 12. The nozzle 12 sprays the hot rinsing liquid onto the vessel 40, thereby rinsing the vessel 40. The rinsing waste liquid generated by rinsing enters the rinsing waste liquid discharge pipe through the bottom of the cleaning operation chamber 10. After being filtered by the rinsing liquid filter 25, the rinsing waste liquid flows back to the rinsing liquid container 20.

[0067] After the rinsing operation is completed, turn on the hot air blower 2. The hot air blower 2 heats the air to about 50°C and sends it into the cleaning operation chamber 10. At the same time, the negative pressure generator 3 creates a negative pressure in the cleaning operation chamber 10 and discharges the air in the cleaning operation chamber 10, forming a circulating hot air in the cleaning operation chamber 10, thereby quickly drying the vessel 40 with hot air.

[0068] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
