Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic cleaning, and specifically to a laboratory ultrasonic cleaning and drying process. Background Art

[0002] An ultrasonic cleaning machine emits high-frequency oscillation signals by an ultrasonic generator, and then converts them into high-frequency mechanical oscillations through a transducer and propagates them into the cleaning liquid. Under the action of ultrasonic waves, the micro-bubbles in the cleaning tank keep vibrating, and these bubbles will cover the surface of the object to be cleaned. When the air pressure reaches a certain level, the bubbles burst, destroying the adsorption between the dirt and the cleaning surface, and gradually shedding the stains on the object surface, so as to achieve the effect of dirt cleaning.

[0003] The existing ultrasonic cleaning machines have the following problems:

[0004] 1. When the existing ultrasonic cleaning machine cleans an object, the object is prone to collision due to vibration, which not only limits the number of fragile utensils such as glassware that can be cleaned, but also causes collision damage to fragile utensils such as glassware.

[0005] 2. Common laboratory ultrasonic cleaning machines do not have the function of high-pressure spray rinsing. After ultrasonic vibration cleaning, manual assistance is still required for rinsing, which takes time and energy.

[0006] 3. Common laboratory ultrasonic cleaning machines do not have the functions of drying, disinfection, and sterilization, which is not conducive to carrying out microbial aseptic tests in the laboratory.

[0007] 4. Common laboratory ultrasonic cleaning machines will generate cleaning wastewater during cleaning. This cleaning wastewater may contain residual chemical drugs, organic pollutants, and even toxic and harmful substances. Directly discharging it may not meet the national discharge standards, and it is also not conducive to the recycling and protection of water resources.

[0008] 5. Working the ultrasonic cleaning machine in a waterless state will damage the machine and affect its service life. Common laboratory ultrasonic cleaning machines do not have warning and pause functions in a waterless state.

[0009] In view of the above problems, the present invention proposes a laboratory ultrasonic cleaning and drying process, which is innovatively designed on the basis of the existing technology. Summary of the Invention

[0010] The purpose of the present invention is to provide a laboratory ultrasonic cleaning and drying process.

[0011] The present invention is implemented by the following technical solutions: A laboratory ultrasonic cleaning and drying process, characterized in that it includes the following steps:

[0012] S1 Ultrasonic cleaning

[0013] Set and display the ultrasonic power, the working time of the ultrasonic generator, the water temperature in the tank, the liquid level of the cleaning tank, the hot air drying time, the ultraviolet disinfection and sterilization time, and the high-pressure spraying time. Perform ultrasonic vibration cleaning on the utensils to be washed, and at the same time, the heating component heats the cleaning water body.

[0014] S2 Spraying, Drying and Sterilizing

[0015] When the preset ultrasonic cleaning time expires, the utensils to be washed in the cleaning tank are automatically lifted to the secondary spraying and rinsing area. The utensils to be washed are rinsed twice by high-pressure water spraying.

[0016] After the secondary spraying and rinsing is completed, hot air drying and ultraviolet disinfection and sterilization work synchronously. The hot air drying device removes the residual water stains and dries the utensils to be washed, and the ultraviolet disinfection and sterilization lamp disinfects and sterilizes the utensils to be washed.

[0017] S3 Circulating Filtration

[0018] Control the water level of the water body in the ultrasonic cleaning box. After the spraying, drying and sterilization are completed, or when the cleaning water body in the ultrasonic cleaning box exceeds the fixed water level, the cleaning water body in the ultrasonic cleaning box or the excess water body exceeding the fixed water level is filtered through a filter element type circulating filter to remove impurities, oil stains, residual chemical drugs, organic pollutants and toxic and harmful substances in the cleaning water body. A part of the treated cleaning water body enters the storage tank for storage and standby.

[0019] When the ultrasonic cleaning box is in a state of no water or lack of water, the treated cleaning water body stored in the storage tank is reused for the ultrasonic cleaning box. If the cleaning water body in the storage tank is surplus, it will be discharged up to standard.

[0020] Further, in the S1, the double-layer spring fixing net is adjusted according to the height position and size status of the utensils to be washed to fix the utensils to be washed and prevent the shaking and collision of glass fragile utensils. Among them, the number of layers of the double-layer spring fixing net can be increased according to the number of utensils to be washed, and the utensils to be washed need to be clamped into the upper and lower layers of spring nets during operation.

[0021] Further, in the S2, the cleaning tank is flipped 360° to drain the cleaning water body in the utensils to be washed and increase the contact area between the spraying and rinsing water body and the utensils to be washed.

[0022] Further, in the S2, when the spraying, drying and sterilization are completed, a buzzer is used for prompting.

[0023] Advantages of the present invention:

[0024] 1. Through the design of the double-layer spring fixing net, this process can solve the problems of less single - time cleaning quantity of the existing ultrasonic cleaning machine and easy collision and damage of glassware, and reduce the loss of glassware in the cleaning process for the laboratory.

[0025] 2. In addition to the conventional ultrasonic cleaning function, this process also has the functions of secondary flushing, hot air drying and ultraviolet disinfection and sterilization, and is applicable to microbiology laboratories.

[0026] 3. This process has the function of circulating and filtering the cleaning water body. The filter element can be replaced regularly. At the same time, the generated cleaning wastewater can be recycled for reuse or discharged up to standard, which is conducive to the conservation and recycling of water resources.

[0027] 4. This process is equipped with a numerical control component and a buzzer, and has a warning and pause function in the waterless state, making the cleaning process automated and intelligent, and solving the problems of direct contact between staff and cleaning liquid and low cleaning efficiency. Specific implementation method

[0028] A laboratory ultrasonic cleaning and drying process includes the following steps:

[0029] S1 Ultrasonic cleaning

[0030] The main function of the ultrasonic cleaning unit is to perform ultrasonic vibration cleaning on the utensils to be washed.

[0031] The utensils to be washed enter through the upper inlet of the cleaning tank arranged inside the ultrasonic cleaning box. According to the height position and size of the utensils to be washed, the double-layer spring fixing net can be adjusted to fix the utensils to be washed and prevent the shaking and collision of fragile glass utensils. Among them, the number of layers of the double-layer spring fixing net can be increased according to the number of utensils to be washed, and the utensils to be washed need to be clamped into the upper and lower spring nets during operation.

[0032] After the utensils to be washed are fixed, the ultrasonic power, the working time of the ultrasonic generator, the water temperature in the tank, the liquid level of the cleaning tank, the hot air drying time, the ultraviolet disinfection and sterilization time and the high-pressure spraying time are set and displayed through the numerical control display screen on the numerical control component.

[0033] After the working parameters are set, the ultrasonic generator emits ultrasonic waves to perform vibration cleaning on the utensils to be washed, and at the same time the heating component heats the cleaning water body, and heating the water body is conducive to the dissolution of pollutants on the utensils to be washed in the water.

[0034] The lifting and turning device arranged on the cleaning tank can drive the cleaning tank to move up and down. When the sliding block on the lifting and turning device moves downward, the cleaning tank is placed in the ultrasonic cleaning unit. When the sliding block moves upward, the cleaning tank is placed in the spraying, drying and sterilization unit.

[0035] S2 Spraying, drying and sterilization

[0036] The main function of the spraying, drying and sterilization unit is to perform secondary flushing, spraying, drying and sterilization on the utensils to be washed.

[0037] When the preset ultrasonic cleaning time expires, the lifting and flipping device automatically lifts the cleaning tank to the spray drying and sterilization box. Subsequently, the rotating high-pressure spray device starts to work, and its blades spray high-pressure water synchronously while rotating to perform a secondary rinse on the utensils to be washed. At the same time, the lifting and flipping device flips the cleaning tank by 360° to facilitate the drainage of the cleaning water in the utensils to be washed and increase the contact area between the spray rinsing water and the utensils to be washed. After the high-pressure spraying ends, the hot air drying device and the ultraviolet disinfection and sterilization lamp work synchronously. The hot air drying device removes the residual water stains and dries the utensils to be washed, and the ultraviolet disinfection and sterilization lamp disinfects and sterilizes the utensils to be washed. When the spray drying and sterilization is completed, a prompt is given through the buzzer.

[0038] S3 Circulating filtration

[0039] The main function of the circulating filtration unit is to filter, process, and recycle the cleaning water.

[0040] After the spray drying and sterilization is completed, or when the cleaning water in the ultrasonic cleaning box exceeds the fixed liquid level, the liquid level float controller will transmit a drainage signal to the numerical control component. Subsequently, the numerical control component will output a signal to open the third water outlet switch, and pump the cleaning water in the ultrasonic cleaning box or the excess water exceeding the fixed liquid level through the third water outlet into the cartridge type circulating filter for filtration treatment to remove impurities, oil stains, residual chemical drugs, organic pollutants, and toxic and harmful substances in the cleaning water. A part of the treated cleaning water enters the liquid storage tank through the fourth water outlet for storage and standby.

[0041] When the ultrasonic cleaning box is in a waterless or water-deficient state, the liquid level float controller will transmit a water replenishment signal to the numerical control component. Subsequently, the numerical control component will output a signal to open the first water outlet switch, and pump the treated cleaning water stored in the liquid storage tank into the ultrasonic cleaning box through the first water outlet, that is, reuse it for the ultrasonic cleaning unit. If the cleaning water in the liquid storage tank is surplus, it will be discharged up to standard through the second water outlet.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
