Description

Technical Field

[0001] This utility model relates to the field of electrical appliance cleaning technology, and more specifically, to a cleaning device for an insulating oil sampling bottle. Background Technology

[0002] Ultrasonic cleaning technology is widely used in modern industrial production and laboratory operations due to its high efficiency, non-destructive nature, and environmental friendliness. Ultrasonic cleaning primarily utilizes the cavitation effect generated by ultrasound waves in liquids. The high-energy impact generated by the rapid formation and collapse of tiny bubbles effectively removes dirt, grease, and other impurities adhering to the surface of insulating oil sampling bottles.

[0003] However, when handling semi-enclosed and insulating oil sampling bottles of different sizes, the ultrasonic waves generated by traditional ultrasonic cleaning devices cannot directly penetrate the interior of the bottle, significantly reducing the cleaning effect. Furthermore, traditional ultrasonic cleaning devices directly discharge the cleaning solution after ultrasonic cleaning, preventing its recycling. Each subsequent ultrasonic cleaning of the insulating oil sampling bottle requires the refilling of new cleaning solution, leading to resource waste, increased cleaning costs, and a substantial reduction in cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies in the prior art and provide a cleaning device for insulating oil sampling bottles. This cleaning device can efficiently and deeply clean the inside and outer surface of the insulating oil sampling bottle, achieving a comprehensive cleaning effect. At the same time, the cleaning solution can be recycled for cleaning, thereby improving cleaning efficiency and reducing cleaning costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a cleaning device for insulating oil sampling bottles, characterized in that it includes a frame, a cleaning tank, an ultrasonic transducer, a circulation tank, a cleaning liquid supply mechanism, a spraying mechanism, a water inlet mechanism, and a drainage mechanism; the cleaning tank and the circulation tank are respectively connected to the frame;

[0006] The water inlet mechanism includes a main water inlet pipe assembly, water inlet pipe one, water inlet pipe two, several side spray pipes and several main spray pipes for spraying the outer surface and interior of the insulating oil sampling bottle. One end of each side spray pipe and main spray pipe is connected to the water inlet pipe assembly, and the other end extends into the cleaning tank. The main spray pipes serve as the working position for the insulating oil sampling bottle to be inverted. One end of water inlet pipe one is connected to the main water inlet pipe assembly, and the other end is connected to an external water supply device. One end of water inlet pipe two is connected to water inlet pipe one, and the other end is connected to the circulation tank.

[0007] The cleaning fluid supply mechanism is connected to the circulation tank to pump the cleaning fluid into the circulation tank; the ultrasonic transducer is installed on the cleaning tank; the drainage mechanism includes a main drain pipe, a first drain pipe, and a second drain pipe. One end of the main drain pipe is connected to the cleaning tank, and the other end is connected to the circulation tank through the first drain pipe. One end of the second drain pipe is connected to the main drain pipe, and the other end is connected to an external drainage device.

[0008] In the above scheme, the insulating oil sampling bottle is placed upside down on the main spray pipe. This invention utilizes ultrasonic technology and a spray mechanism to efficiently and deeply clean the outer surface and interior of the insulating oil sampling bottle, achieving a comprehensive cleaning effect. Furthermore, a circulating water path is formed between the circulation tank and the cleaning tank, allowing the cleaning solution to circulate continuously during the cleaning process. This significantly reduces the consumption of cleaning solution, improving cleaning efficiency and lowering cleaning costs.

[0009] The main water inlet pipe assembly includes a main water inlet pipe, a water distributor, and a water pump; the input end of the main water inlet pipe is connected to water inlet pipe one and water inlet pipe two respectively, and the output end is connected to the water distributor; the water pump is installed on the main water inlet pipe; the water distributor is provided with several interfaces, and several side spray pipes and several main spray pipes are respectively connected to the interfaces of the water distributor.

[0010] The spray nozzle of the side spray pipe is opposite to the position where the insulating oil sampling bottle is inverted; the main water inlet pipe is equipped with a pressure sensor for monitoring the water inlet pressure.

[0011] The first water inlet pipe is equipped with an external water inlet solenoid valve; the second water inlet pipe is equipped with a circulating water inlet solenoid valve.

[0012] The cleaning device also includes a main exhaust pipe; each main spray pipe is equipped with a branch exhaust pipe for venting the air inside the insulating oil sampling bottle during water storage cleaning; each branch exhaust pipe is connected to one end of the main exhaust pipe, and the other end of the main exhaust pipe is located above the cleaning tank or outside the cleaning tank.

[0013] A drainage pump is installed on the main drainage pipe; a circulating drainage solenoid valve is installed on the first drainage pipe; and an external drainage solenoid valve is installed on the second drainage pipe.

[0014] The main drain pipe is equipped with a water level sensor for monitoring the water level in the cleaning tank.

[0015] The cleaning fluid supply mechanism includes a cleaning fluid storage box, an inlet pipe, and an inlet pump mounted on the frame; the inlet pump is mounted on the inlet pipe, one end of which is connected to the cleaning fluid storage box and the other end is connected to the circulation tank.

[0016] The circulating tank is equipped with a heater for heating the liquid. The heater of this invention can be a PTC heater, used to heat the liquid in the circulating tank. The PTC heater uses PTC ceramic material as the heating element. This material has a positive temperature coefficient characteristic, meaning that as the temperature increases, the resistance also increases, thereby achieving automatic adjustment of heating power, avoiding overheating, and improving safety.

[0017] The cleaning tank and the circulation tank are each equipped with a drain pipe to prevent liquid overflow; the drain pipes of the cleaning tank and the circulation tank are respectively connected to external drainage equipment.

[0018] The cleaning device for the insulating oil sampling bottle of this utility model also includes a control system, which is connected to a water inlet pump, a drain pump, a liquid inlet pump, an external water inlet solenoid valve, a circulating water inlet solenoid valve, a circulating drain solenoid valve, an external drain solenoid valve, a pressure sensor, a water level sensor, and an ultrasonic transducer. The control system controls each actuator to operate in sequence according to a preset program to achieve automatic switching between ultrasonic cleaning mode and clean rinsing mode.

[0019] Before the cleaning device for the insulating oil sampling bottle of this utility model is put into operation, the insulating oil sampling bottle is first placed upside down on the main spray pipe. The working process is as follows:

[0020] 1. Ultrasonic cleaning mode:

[0021] (1) Control the opening of the external water inlet solenoid valve and the circulating water inlet solenoid valve so that the tap water from the external equipment enters the circulating tank.

[0022] (2) Control the pump to deliver cleaning fluid to the circulation tank; control the external water inlet solenoid valve to close, and control the water inlet pump to deliver the cleaning water mixed with cleaning fluid from the circulation tank to the cleaning tank for water storage through the spray mechanism. When the main spray pipe is spraying, the air inside the insulating oil sampling bottle can be discharged through the exhaust pipe, so that the insulating oil sampling bottle can be immersed in the cleaning water.

[0023] (3) Control the operation of the ultrasonic transducer. The ultrasonic transducer generates high-frequency ultrasonic signals, which are converted into mechanical vibrations. These mechanical vibrations propagate through the cleaning water in the cleaning tank and form a large number of tiny bubbles in the liquid. These bubbles rapidly increase in size and suddenly burst under the action of ultrasonic waves, generating strong shock waves and local high temperature and pressure, i.e., cavitation effect. The cavitation effect can effectively destroy the bonding force between the stains and the insulating oil sampling bottle, causing the stains to fall off quickly, achieving a cleaning effect on the inside and outside surface of the insulating oil sampling bottle.

[0024] (4) After cleaning, control the solenoid valve of the circulating drain to open and control the drain pump to discharge the cleaning water of the cleaning tank into the circulating tank. The cleaning water in the circulating tank can be used for the next ultrasonic cleaning mode.

[0025] 2. Clean Rinse Mode:

[0026] The system controls the opening of the external water inlet solenoid valve and the closing of the circulating water inlet solenoid valve. It also controls the water pump to deliver external tap water to the spray mechanism, providing stable and sufficient water pressure so that the side spray pipes and main spray pipes can respectively flush the inside and outside surfaces of the insulating oil sampling bottle, thoroughly removing residual dirt and cleaning agents. Conversely, the system controls the closing of the circulating drain solenoid valve and the opening of the external drain solenoid valve, controlling the drain pump to discharge the clean water from the cleaning tank to the external drainage system.

[0027] The advantages of the cleaning device for the insulating oil sampling bottle of this utility model are:

[0028] 1. High-efficiency cleaning: This invention introduces a cleaning fluid circulation mechanism through ultrasonic cleaning mode. Utilizing the cavitation effect of ultrasound and the circulating flow of cleaning water, the ultrasound waves can act more evenly on the inner and outer surfaces of the insulating oil sampling bottle, quickly breaking down the adhesion between stains and the surface, causing the stains to detach rapidly. Simultaneously, the powerful water flow of the clean rinsing mode thoroughly removes residual dirt and cleaning agents, achieving high-efficiency and deep cleaning.

[0029] 2. Environmental Protection and Energy Saving: This utility model separates the ultrasonic cleaning mode structure from the clean rinsing mode structure. This design not only improves the cleaning effect but also demonstrates significant advantages in environmental protection and energy saving. The cleaning fluid circulation in the ultrasonic cleaning mode structure allows the cleaning fluid to be continuously recycled during the cleaning process, thereby greatly reducing the consumption of cleaning fluid. Secondly, the independent design of the clean rinsing mode structure and the ultrasonic cleaning mode structure avoids mutual interference between the two. This design ensures that each mode structure operates in its optimal state, thus fully utilizing its maximum function. This not only improves cleaning efficiency but also avoids resource waste caused by mutual influence between the structural modes.

[0030] 3. Wide range of applications: This device is suitable for cleaning insulating oil sampling bottles and other items of various shapes and sizes, and has a wide range of applications.

[0031] Compared with the prior art, the present invention has the following advantages and beneficial effects: the cleaning device of the insulating oil sampling bottle of the present invention can perform efficient and deep cleaning of the inside and outer surface of the insulating oil sampling bottle, achieving a comprehensive cleaning effect; at the same time, the cleaning solution can be recycled for cleaning, thereby improving cleaning efficiency and reducing cleaning costs.
