[0025] The following is a detailed description of a water bath cleaning trolley for forming a negative pressure device of the present invention with reference to the accompanying drawings.
[0026] like Figure 1-4 As shown, an embodiment of a water bath cleaning trolley for forming a negative pressure device according to the present invention includes a trolley frame 1 and a plurality of casters 11 mounted on the trolley frame 1, and the trolley frame 1 is movable by the casters 11. A water bath 2 for storing water is mounted on a bottom plate 12 within the trolley frame 1, a cleaning liquid storage tank 3 is mounted in the middle of the water bath 2, and the tank body of the cleaning liquid storage tank 3 is placed within the water bath 2, and the tank cover of the cleaning liquid storage tank 3 is placed on the top of the water bath 2; the tank body of the cleaning liquid storage tank 3 is made of a heat-conducting material, and after the water in the water bath 2 is heated to a specified temperature, the heat is transferred to heat the cleaning liquid in the cleaning liquid storage tank 3, and then the heated cleaning liquid is used to clean the negative pressure pipeline.
[0027] In order to heat the water in the water bath 2, a heating tube 24 is installed inside the water bath 2 through a mounting tube holder 23, and the energized end of the heating tube 24 is placed outside the water bath 2. When the heating tube 24 is energized, the water in the water bath 2 can be heated. In addition, the mounting tube holder 23 can be removed from the water bath 2 to facilitate replacement and maintenance of the heating tube 24. A temperature sensor 25 for detecting the water temperature is provided on the water bath 2. When the temperature sensor 25 detects that the water is heated to the set temperature, the heating tube 24 stops heating.
[0028] In addition, the water bath 2 is also equipped with a drain valve 21 and a first liquid level gauge 22 for detecting the liquid level. After opening the drain valve 21, the remaining water and scale in the water bath 2 can be discharged, which facilitates the replacement of the water in the water bath 2. When water replenishment is needed, water can be directly transported into the water bath 2 from the drain valve 21. Moreover, under the action of the first liquid level gauge 22, the water level in the water bath 2 can be observed at all times, and the water level can also be observed after heating multiple times. In addition, an anti-dry-burn device 26 is installed at the bottom of the inner wall of the water bath 2 to prevent the water level from being too low. The anti-dry-burn device 26 can be a liquid level sensor. When the anti-dry-burn device 26 detects that the water level is too low, it cannot energize the heating tube 24 to prevent dry-burning when the water level is too low.
[0029] Furthermore, a liquid conduit 31 for draining the cleaning liquid is connected to the bottom of the cleaning liquid storage tank 3. A drain valve 32 connected to the liquid conduit 31 is installed on the outside of the water bath 2. When the drain valve 32 is opened, positive pressure is applied to the interior of the cleaning liquid storage tank 3, thereby forcing the cleaning liquid out. A drain pipe 33 is connected to the outlet of the drain valve 32 for draining the cleaning liquid into the negative pressure pipe. The water in the water bath 2 is first heated by the heating pipe 24, thereby transferring heat to the cleaning liquid, thereby heating the cleaning liquid. After heating is completed, the drain valve 32 is opened to apply positive pressure to the interior of the cleaning liquid storage tank 3. The heated cleaning liquid is discharged from the drain pipe 33 and discharged into the negative pressure pipe. By heating the cleaning liquid, the dissolution rate of the crystals in the negative pressure pipe is accelerated, thereby improving the cleaning efficiency and enhancing the cleaning effect.
[0030] A suction valve 34 is provided at the top of the cleaning liquid storage tank 3, and a suction pipe 35 for sucking and recovering the cleaning liquid in the negative pressure pipe is connected to the liquid inlet of the suction valve 34; the heated cleaning liquid is discharged into the negative pressure pipe through the discharge pipe 33, and the crystals in the negative pressure pipe are dissolved and cleaned, and then the suction pipe 35 is connected to the negative pressure pipe to apply negative pressure to the inside of the cleaning liquid storage tank 3, and the cleaning liquid in the negative pressure pipe is sucked and recovered through the suction pipe 35 and recycled back into the cleaning liquid storage tank 3; a positive and a negative pressure are applied to the inside of the cleaning liquid storage tank 3 to achieve cleaning of the negative pressure pipe. A pressure port 36 is also provided at the top of the cleaning liquid storage tank 3 and is connected to the inside thereof. The pressure port 36 is used to connect to a vacuum generator or a booster pump (not shown in the figure). By running the vacuum generator or the booster pump, positive or negative pressure can be applied to the inside of the cleaning liquid storage tank 3.
[0031] A positive pressure control system 4 for controlling the positive pressure inside the cleaning liquid storage tank 3 and a negative pressure control system 5 for controlling the negative pressure inside the cleaning liquid storage tank 3 are installed on the trolley frame 1. By operating the positive pressure control system 4 and the negative pressure control system 5, the operation of the vacuum generator or the booster pump (not shown in the figure) can be controlled. The positive pressure control system 4 and the negative pressure control system 5 are both existing technologies. The positive pressure control system 4 includes a positive pressure switch, an air blowing switch, and a liquid discharge switch, etc., to control the positive pressure inside the cleaning liquid storage tank 3. The negative pressure control system 5 includes a negative pressure regulating valve, a vacuum pressure gauge, a negative pressure switch, and a liquid return switch, etc., to control the negative pressure inside the cleaning liquid storage tank 3. They are not described in detail here. In addition, a second level gauge 37 for detecting the liquid level of the cleaning liquid is provided next to the cleaning liquid storage tank 3, and the display part of the second level gauge 37 is placed outside the water bath 2. The second level gauge 37 can be used to observe the liquid level of the cleaning liquid in the cleaning liquid storage tank 3 at all times, so that the cleaning liquid can be replenished in time. A refill valve 38 for replenishing cleaning liquid is provided at the top of the cleaning liquid storage tank 3. When the cleaning liquid in the cleaning liquid storage tank 3 is less, the refill valve 38 is connected to a device for providing cleaning liquid (not shown in the figure) and the device is operated to replenish the cleaning liquid into the cleaning liquid storage tank 3.
[0032] The trolley frame 1 is equipped with a first filter 61 connected to the drain pipe 33 and used to filter the discharged cleaning liquid. It is also equipped with a second filter 62 connected to the suction pipe 35 and used to filter the recovered cleaning liquid. When cleaning the negative pressure pipeline, the discharged cleaning liquid is filtered by the first filter 61, and the recovered cleaning liquid is filtered by the second filter 62, allowing the cleaning liquid to be recycled multiple times, saving costs. The trolley frame 1 is equipped with a control panel 7 for controlling the entire cleaning trolley. By operating the control panel 7, the water bath cleaning trolley can be cleaned according to the instructions.
[0033] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
