Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically to a three-way valve-linked water-air dual-circulation cleaning device. Background Technology
[0002] Steam cleaning utilizes high-temperature steam to decompose and remove stains. When high-pressure steam is sprayed onto an object's surface, the heat of the steam causes the stains to rapidly heat up and expand, while the steam pressure also impacts the stains. This combination makes it easier for the stains to separate from the object's surface. Existing steam cleaning equipment includes a steam source, a pressurization device connected to the steam source, a cleaning pipeline connected to the pressurization device, and a cleaning nozzle assembly located at the end of the cleaning pipeline. Continuous cleaning operations consume a large amount of steam and heat energy, which should be recycled. This application is made to address this need. Utility Model Content
[0003] The purpose of this invention is to provide a three-way valve-linked water-steam dual-circulation cleaning device with a reasonable structure and reliable operation, so as to solve the problem of high steam and heat energy consumption caused by continuous cleaning operations and achieve energy saving.
[0004] The technical solution of this utility model is:
[0005] A three-way valve-linked water-steam dual-circulation cleaning device includes a cleaning chamber, a steam source, a pressurizing device, a cleaning pipeline connected to the pressurizing device, and a cleaning nozzle assembly located at the end of the cleaning pipeline. The key technical features are: a gas phase recovery pipeline is located at the top of the cleaning chamber; a first circulation pump is located at the other end of the gas phase recovery pipeline; a heater is located at the end of the outlet pipeline of the first circulation pump; a buffer chamber is located at the end of the outlet pipeline of the heater; the outlet pipeline of the buffer chamber is connected to one inlet of a first three-way valve; the other inlet of the first three-way valve is connected to the gas phase outlet of the steam source; the outlet of the first three-way valve is connected to the inlet of the pressurizing device; and a pressure sensor is located in the buffer chamber. A liquid phase recovery pipeline is located at the bottom of the cleaning chamber; a filter device is connected at the other end of the liquid phase recovery pipeline; a second circulation pump is connected to the outlet pipeline of the filter device; the outlet pipeline of the second circulation pump is connected to one inlet of a second three-way valve; the other inlet of the second three-way valve is connected to a water supply pipeline; the outlet of the second three-way valve is connected to the liquid phase inlet of the steam source; and a liquid level sensor is located in the filter device.
[0006] The aforementioned three-way valve-linked water-steam dual-circulation cleaning equipment has a temperature sensor installed on the outlet pipe of the heater.
[0007] The aforementioned three-way valve-linked water-vapor dual-circulation cleaning equipment includes a filter device comprising a housing, a filter screen disposed within the housing, an inlet chamber and a purification chamber separated by the filter screen, and a liquid level sensor located at the top of the purification chamber.
[0008] The beneficial effects of this utility model are:
[0009] After the cleaning process, the high-pressure, high-temperature steam forms two parts: a cooled gas phase and a cooled liquid phase. The cooled gas phase is recovered using a gas phase recovery pipeline, a heater, and a buffer chamber. When the pressure sensor detects that the pressure in the buffer chamber has reached the set pressure, the first three-way valve switches, and the first circulation pump introduces the gas phase from the buffer chamber into the pressurization device, achieving the recycling of the cooled gas phase. Simultaneously, the cooled liquid phase is recovered using a liquid phase recovery pipeline and a filtration device. When the liquid level sensor detects that the liquid level in the purification chamber has reached the set height, the second three-way valve switches, and the second circulation pump introduces purified water into the steam source as steam source water, achieving the recycling of the cooled liquid phase. This invention, through the dual recycling of the cooled gas and liquid phases, solves the problem of high steam and heat energy consumption caused by continuous cleaning operations, achieving energy saving.

[0012] The present invention will be described in detail with reference to the accompanying drawings.
[0013] like Figure 1 As shown, the three-way valve-linked water-steam dual-circulation cleaning equipment includes a cleaning chamber 7, a steam source 1, a pressurizing device 13, a distributor 10 connected to the pressurizing device 13, multiple cleaning pipelines 11 connected to the distributor 10, and a cleaning nozzle assembly 8 located at the end of the cleaning pipelines 11.
[0014] The cleaning chamber 7 is equipped with a gas phase recovery pipeline 9 at its top. A first circulation pump 6 is located at the other end of the gas phase recovery pipeline 9. A heater 5 is located at the end of the outlet pipeline of the first circulation pump 6. A buffer chamber 3 is located at the end of the outlet pipeline of the heater 5. The outlet pipeline of the buffer chamber 3 is connected to one inlet of a first three-way valve 2. The other inlet of the first three-way valve 2 is connected to the gas phase outlet of the steam source 1. The outlet of the first three-way valve 2 is connected to the inlet of a pressurizing device 13. A pressure sensor 4 is located in the buffer chamber 3. In this embodiment, a temperature sensor 12 is located on the outlet pipeline of the heater 5.
[0015] The bottom of the cleaning chamber 7 is provided with a liquid phase recovery pipeline 20. The other end of the liquid phase recovery pipeline 20 is connected to a filter device 19. The outlet pipeline of the filter device 19 is connected to a second circulation pump 16. The end of the outlet pipeline of the second circulation pump 16 is connected to one inlet of a second three-way valve 14. The other inlet of the second three-way valve 14 is connected to a water supply pipeline 15. The outlet of the second three-way valve 14 is connected to the liquid phase inlet of the steam source 1. The filter device 19 is provided with a liquid level sensor 17. The filter device 19 includes a housing, a filter screen 18 disposed in the housing, and a water inlet chamber and a purification chamber separated by the filter screen 18. The liquid level sensor 17 is located at the top of the purification chamber.
[0016] Working principle:
[0017] 1. High-temperature steam generated by the steam source is transmitted to the pressurization device 13 through the first three-way valve 2. The high-pressure high-temperature steam is sprayed onto the surface of the object to be cleaned in the cleaning chamber 7 through the distributor 10, the cleaning pipeline 11 and the cleaning nozzle assembly 8 to achieve the cleaning purpose.
[0018] 2. After the cleaning operation, the high-pressure, high-temperature steam forms two parts: a cooled gas phase and a cooled liquid phase. The cooled gas phase, under the action of the first circulation pump 6, enters the heater 5 through the gas phase recovery pipeline 9, and after being heated, enters the buffer chamber 3 for storage. When the pressure sensor 4 detects that the pressure in the buffer chamber 3 has reached the set pressure, the first three-way valve 2 switches to connect the buffer chamber 3 and the pressurization device 13, and the gas phase in the buffer chamber 3 enters the pressurization device 13, realizing the first recycling.
[0019] 3. After the high-pressure and high-temperature steam is cooled, the liquid phase is collected by the liquid phase recovery pipeline 20 and sent to the filter device 19. After the filter device 19 filters out solid impurities, when the liquid level sensor 17 detects that the liquid level in the purification chamber has reached the set height, the second three-way valve 14 tangentially connects the purification chamber and the steam source 1. The second circulation pump 16 introduces the purified water into the steam source as steam source water, realizing the second recycling.
[0020] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
