[0002] Most existing ultrasonic tanks are made of an integral quartz tank. The cost of the entire tank is high, the procurement cycle is long, and it is not conducive to assembly line production. When performing ultrasound, a larger outer tank is required. A large amount of liquid is injected into the outer tank to immerse the bottom of the quartz tank. Then, ultrasonic conduction cleaning is performed, which consumes a lot of water.

[0003] In the prior art, to address this problem, the main tank is designed to be made of other non-metallic materials combined with a quartz bottom plate, so that water only needs to exceed the bottom quartz plate. However, in this solution, as the ultrasonic time increases, the bottom surface of the quartz bottom plate will be covered with small bubbles, thereby affecting the transmission of ultrasonic waves.

[0004] Therefore, a negative pressure exhaust circulation system is provided to solve the technical problem in the prior art that air is generated at the bottom of the quartz bottom plate and affects the transmission of ultrasonic waves. Utility Model Content

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Most existing ultrasonic tanks are quartz tanks with an integral structure. The cost of the entire tank is high, the procurement cycle is long, and it is not conducive to assembly line production. When performing ultrasound, a larger auxiliary tank is required. A large amount of liquid is injected into the auxiliary tank to immerse the bottom of the quartz tank body, and then ultrasonic conduction cleaning is performed, which consumes a large amount of water. In order to solve this problem, the existing technology designs the main tank to be a non-metallic material combined with a quartz bottom plate. The water only needs to exceed the bottom quartz plate. However, in this solution, there will be air between the bottom of the quartz bottom plate and the bottom surface of the inner wall of the main tank, which will affect the transmission of ultrasonic waves.

[0037] In order to solve the above technical problems, in at least one embodiment, a negative pressure exhaust circulation system is provided, comprising: an ultrasonic tank 30 and a main tank 1; wherein the main tank 1 is inserted into the inside of the ultrasonic tank 30, and the outer wall of the main tank 1 is in contact with the inner wall of the ultrasonic tank 30; and an exhaust box 8, whose exhaust end is arranged at the bottom of the main tank 1; wherein the exhaust box 8 is suitable for extracting the gas between the bottom of the main tank and the ultrasonic tank, so that the liquid level in the ultrasonic tank 30 is in contact with the bottom surface of the main tank 1;

[0038] By providing an exhaust box 8, the exhaust end of the exhaust box 8 is set between the quartz bottom plate 2 and the liquid surface of the ultrasonic tank 30. When the pump is started, negative pressure is evacuated between the two to extract the air between the two, so that there is no air between the quartz bottom plate 2 and the liquid surface, thereby improving the ultrasonic transmission effect.

[0039] In some embodiments, before work, water is added into the main tank 1 so that the added water submerges the quartz bottom plate 2 at the bottom of the main tank 1. The quartz bottom plate 2 and the main tank 1 are installed in the form of a pressure strip, and sealing strips are set above and below the quartz bottom plate 2 for sealing.

[0040] In some embodiments, the ultrasonic generator 3 is arranged at the bottom of the ultrasonic tank 30, the center of the inner bottom surface of the ultrasonic tank 30 is hollowed out, and its outer wall is fitted with the main tank 1 to wrap the main tank 1. The hollow part of the inner bottom surface of the ultrasonic tank 30 is matched with the bottom surface of the quartz bottom plate 2 in the main tank 1, so that the liquid level in the ultrasonic tank 30 infiltrates the bottom surface of the quartz bottom plate 2. At this time, the quartz bottom plate 2 is infiltrated by the liquid in the main tank 1 and the ultrasonic tank 30, the ultrasonic generator 3 is started to work, and the pneumatic pump 81 is started at the same time. The air between the quartz bottom plate 2 and the bottom surface of the main tank 1 is extracted into the exhaust pipe through the exhaust end of the exhaust box 8, and the pneumatic pump 81 is continuously started. As the ultrasonic generator 3 continues to work, small bubbles will continue to appear on the bottom surface of the quartz bottom plate 2, and the air in the generated bubbles will be continuously extracted through the exhaust pipe to ensure that there is no air gap between the quartz bottom plate 2 and the liquid level in the ultrasonic tank to avoid affecting the working effect.

[0041] In some embodiments, the gas exhausted from the exhaust box 8 passes through the one-way valve on the exhaust pipe 80 and is introduced into the outer wall of the ultrasonic tank 30 by the pneumatic pump 81. As can be seen from the figure, the exhaust pipe 80 is in contact with the outer wall of the ultrasonic tank 30. After the gas is introduced into it, it will stay inside the outer wall of the ultrasonic tank 30 and will not invade between the ultrasonic tank 30 and the quartz bottom plate 2. In the process of extracting the bubbles at the bottom of the quartz bottom plate 2, it is inevitable that part of the liquid in the ultrasonic tank 30 will be extracted. The ultrasonic tank 30 is connected to the water adding pipe 31, and water is added to the ultrasonic tank 30 by manually opening the manual water adding ball valve 32 to ensure that the liquid always soaks the bottom surface of the quartz bottom plate 2.

[0042] In some embodiments, an overflow groove 6 is provided on the upper part of the outer wall of the main groove 1. The overflow groove 6 is placed on the top of the ultrasonic groove 30 and is used to carry the liquid overflowing from the main groove 1. The water outlets of the overflow groove 6 and the ultrasonic groove 30 are both connected to the first drain pipe 5. After the work is completed, the first manual ball valve 50 is opened to discharge the liquid in the overflow groove and the ultrasonic groove 30.

[0043] In some embodiments, the bottom of the main tank 1 is separately connected to a second drain pipe 7 , and the liquid in the main tank 1 is drained by opening the second manual ball valve 70 .

[0044] In some embodiments, a side-mounted immersion heater 4 is used on the inner wall of the main tank 1 to ensure that the transmission of ultrasonic waves is not blocked.

[0045] In summary, by providing an exhaust box, the exhaust end of the exhaust box is set between the quartz bottom plate and the liquid surface of the ultrasonic tank, and negative pressure air is pumped between the two when the pump is started, and bubbles generated in the quartz bottom plate as the ultrasonic time increases are extracted in time, so that there is no air between the quartz bottom plate and the liquid surface, thereby improving the ultrasonic conduction effect.
