Description

TECHNICAL FIELD

[0001] The present application relates to the field of industrial equipment cleaning, in particular to a water-gas switching equipment cleaning device. BACKGROUND

[0002] In the field of cleaning equipment technology, the limitations of traditional cleaning methods are gradually becoming the bottleneck of industry efficiency improvement. For example, the core problem of the widely used high-pressure water cleaning is the contradiction between cleaning efficiency and resource consumption: when facing stubborn stains such as hardened grease, carbon deposition and deep dust, high-pressure water flow is difficult to achieve complete stripping, and contaminants are still likely to remain after cleaning; at the same time, this method requires continuous output of high-flow water, and the water consumption of a single cleaning usually reaches 3-5 times that of ordinary cleaning methods, which is significantly insufficient in terms of economy in water resource shortage scenarios.

[0003] Another type of mainstream gas-water mixed cleaning, although it enhances the stain stripping ability through the impact effect of gas-liquid two-phase flow, to some extent, makes up for the efficiency shortcomings of high-pressure water cleaning, but it exposes serious synergy defects in the key drying link. The cleaning and drying system of most current equipment is in a "segmented independent" operation mode, lacking a dynamic linkage control mechanism - it cannot adjust the drying parameters (such as hot air temperature, air speed, drying time) in real time according to the material quality (such as metal, plastic, glass) of the cleaning object, surface humidity distribution and stain residue, nor can it intelligently adapt to changes in environmental temperature and humidity. This "one-size-fits-all" operation mode often leads to two extreme results: either excessive energy output to pursue drying effect, causing inefficient loss of electrical and thermal energy; or due to insufficient parameter adaptation, there are problems such as local water residue, uneven drying, which affect the quality of subsequent assembly, painting and other processes.

[0004] Especially in winter low temperature environment, the drawbacks of traditional drying method are more prominent. When the environmental temperature is lower than 5℃, the heat exchange efficiency of ordinary hot air drying system decreases significantly, and it needs to extend 2-3 times of drying time to reach the basic drying standard; if it encounters subzero temperature, surface water may even freeze, not only completely losing the drying function, but also possibly causing freeze cracking damage to the metal parts of the cleaning object, seriously restricting the normal use of the equipment in cold regions or winter conditions.

[0005] In summary, how to ensure cleaning effect while reducing energy consumption, and achieving good cleaning and drying effect in different environments has become a problem that researchers in the field need to solve. SUMMARY

[0006] The technical problem to be solved by the present application is: how to ensure cleaning effect while reducing energy consumption, and achieving good cleaning and drying effect in different environments; To solve the above technical problems, the technical scheme adopted by the present application is: The present application is a water-gas switching equipment cleaning device, comprising: a water inlet pipe, a first electromagnetic valve for selecting water inlet being arranged at one end of the top of the water inlet pipe, one end of the bottom of the water inlet pipe being located in a transition pipe, a Venturi tube being communicated with the bottom of the transition pipe, and a cleaning outlet being at the bottom of the Venturi tube; a second electromagnetic valve for selecting air inlet being arranged on one side of the transition pipe.

[0007] Further, the inner diameter of the water inlet pipe gradually decreases downward along the axis of the water inlet pipe.

[0008] Further, a collection cover with an opening downward is arranged at the Venturi tube.

[0009] Further, a baffle gradually expanding outward is arranged at the bottom of the collection cover, and the bottom of the baffle is lower than the cleaning outlet.

[0010] Further, a perforated plate is connected between the bottom of the collection cover and the top of the baffle, and the perforated plate is arranged at the throat of the Venturi tube.

[0011] Further, a three-phase separator is connected at the opening of the sidewall of the collection cover.

[0012] Further, the air outlet pipe of the three-phase separator can be connected with the second electromagnetic valve, and the liquid outlet pipe of the three-phase separator can be connected with the first electromagnetic valve.

[0013] Further, a temperature sensor, a dust concentration sensor, and a heater are arranged on the Venturi tube.

[0014] The present application has the following beneficial effects: 1. The present application uses the strong energy generated by the breaking of gas bubbles during gas-liquid mixing to significantly enhance the cleaning effect, and can effectively remove stubborn stains and dust, thereby improving the cleaning efficiency.

[0015] 2. The arrangement of the Venturi nozzle system enables the cleaning mode to be flexibly switched according to actual needs, and when facing general dust, pure water cleaning is adopted, and when encountering difficult-to-remove stains, strong cleaning is used by utilizing the cavitation effect, which not only ensures the cleaning effect, but also reduces energy consumption.

[0016] 3. The device can automatically adjust the cleaning and drying processes according to the dust concentration and air temperature, realizing the intelligentization and automation of cleaning and drying, without the need for manual intervention, thereby improving the work efficiency and avoiding energy waste, and achieving good cleaning and drying effects in different environments.

[0017] 4. The heater in this device can heat and dry the air in a low-temperature environment, ensuring that objects can be dried quickly even in low-temperature conditions such as winter, thus expanding the range of applications of the device. Attached Figure Description

The top of the water inlet pipe 1 is the water inlet 11, and a first solenoid valve for selective liquid intake is provided at the water inlet 11. In this embodiment, state one: when the second solenoid valve is closed and the first solenoid valve is open, this is suitable for ordinary cleaning scenarios. The cleaning fluid enters from the water inlet pipe 1 and is sprayed out from the cleaning outlet 31 through the venturi tube 3 to achieve the cleaning function. State 2: When the second solenoid valve is open and the first solenoid valve is open, this is suitable for scenarios requiring powerful cleaning. The cleaning fluid and gas are mixed and then accelerated in the venturi tube 3 before being sprayed out to achieve powerful cleaning of the equipment surface. State three: when the second electromagnetic valve is opened and the first electromagnetic valve is closed, which is suitable for the dry scene. The gas is accelerated by the venturi tube 3 and sprayed from the cleaning outlet 31 to achieve drying after equipment cleaning.

[0022] In some possible embodiments, the inner diameter of the water inlet pipe 1 gradually decreases along the axis of the water inlet pipe 1 downwardly; In the present embodiment, since the inner diameter of the water inlet pipe 1 gradually decreases, the flow rate of the cleaning liquid gradually increases when the cleaning liquid passes through the water inlet pipe 1, thereby enhancing the cleaning effect.

[0023] In some possible embodiments, the venturi tube 3 is provided with a collecting cover 4 with an opening downwardly; In the present embodiment, during the cleaning process, since the cleaning outlet 31 of the venturi tube 3 forms a local negative pressure, the collecting cover 4 is arranged to collect the splashed solid-liquid mixture generated during the cleaning process.

[0024] In some possible embodiments, the collecting cover 4 is provided with a baffle 5 with a gradually outwardly expanding bottom, and the bottom of the baffle 5 is lower than the cleaning outlet 31; By arranging the baffle 5, the liquid can be prevented from splashing to both sides during the cleaning process.

[0025] In some possible embodiments, the collecting cover 4 and the baffle 5 are connected by a perforated plate 6, and the perforated plate 6 is arranged at the throat 32 of the venturi tube 3; In the present embodiment, the edge of the perforated plate 6 is sealingly connected to the inner wall of the collecting cover 4, the perforated plate 6 can separate the solid impurities with a large diameter, and the remaining splashed solid-liquid mixture is collected by the collecting cover 4 under the negative pressure.

[0026] In some possible embodiments, a three-phase separator 7 is connected to the sidewall opening of the collecting cover 4; In the present embodiment, the mixture entering the collecting cover 4 enters the three-phase separator 7, the three-phase separator separates the mixture, the liquid is introduced into the water tank 71, the solid is discharged from the discharge port 72, and the gas is discharged from the top gas outlet pipe 73.

[0027] In some possible embodiments, the gas outlet pipe 73 of the three-phase separator 7 can be connected to the second electromagnetic valve, and the liquid outlet pipe (not shown in the figure) of the water tank 71 of the three-phase separator 7 can be connected to the first electromagnetic valve; In the present embodiment, the filtered gas separated by the three-phase separator 7 can re-enter the transition pipe 2 to participate in cleaning, and the filtered liquid separated by the three-phase separator 7 can re-enter the water inlet pipe 1 to participate in cleaning.

[0028] In some possible embodiments, the Venturi tube 3 is provided with a temperature sensor 8, a dust concentration sensor 9, and a heater 10; The dust concentration sensor 9 is used to detect the dust content of the cleaning surface in real time, and the state one and state two conversion is controlled according to the dust concentration data. If the dust content is small, the cleaning in state one is performed; if the dust content is large, the cleaning in state two is performed.

[0029] With the cleaning, when the dust concentration sensor 9 detects that the dust concentration is reduced below the dry threshold, it is switched to state three to dry the equipment. In the drying process, if the temperature sensor 8 detects that the ambient temperature is low, the heater 10 heats the air according to the set temperature. The temperature sensor 8 continuously monitors the ambient temperature and the temperature of the ejected air, and the automatic control system adjusts the power of the heating device in real time according to the temperature data to ensure the drying effect and efficiency, prevent the equipment from freezing, and accelerate the drying.
