[0023] The utility model will be described in further detail below in combination with the drawings and specific embodiments:

[0024] For example, Figures 1 to 8As shown, a chemical tank with self-adaptive adjusting air inlet structure, including tank body 1, the top of tank body 1 is provided with air inlet 2, the bottom is provided with air outlet 3, air inlet 2 is provided with air inlet valve 4, air outlet 3 is provided with air outlet valve 5. Air inlet valve 4 includes air inlet cylinder 6, the top and bottom of air inlet cylinder 6 are open and the bottom is fixedly provided with baffle 7, the center of baffle 7 penetrates and rotates shaft 8, the top end of shaft 8 is coaxially fixedly connected with the output shaft of first motor 9 arranged on the top of baffle 7, the bottom end is coaxially fixedly connected with rotating disc 10, rotating disc 10 abuts with baffle 7 and a plurality of fan-shaped air inlet through holes 11 are formed on both of them, air inlet through hole 11 on rotating disc 10 corresponds with air inlet through hole 11 on baffle 7 one by one and can coincide and stagger. The outer side of the middle part of air inlet cylinder 6 is fixedly sleeved with square mounting plate 12, the left and right sides of mounting plate 12 are both provided with through slot 13 along the front and back direction, the front and back sides of the bottom of mounting plate 12 are both fixedly provided with positioning block 14. The outer top of tank body 1 corresponding to air inlet 2 is fixedly provided with square support plate 15, the center of support plate 15 is provided with through hole 16 communicated with air inlet 2, the left and right sides of the top of support plate 15 are both provided with second motor 17, the output shaft of second motor 17 extends out of support plate 15 upwards and is fixedly connected with pressing block 18, the front and back sides of the top of support plate 15 are both provided with positioning slot 19. The lower part of air inlet cylinder 6 extends into tank body 1 through through hole 16 and air inlet 2, mounting plate 12 abuts on support plate 15, positioning block 14 corresponds with the same side positioning slot 19 and is inserted, pressing block 18 penetrates the same side through slot 13 to the top of mounting plate 12 and abuts on the top of mounting plate 12 after rotating 90 degrees. Tank body 1 is communicated with pressure gauge 20, the outer side wall of tank body 1 is fixedly provided with controller 21 and sound-light alarm 22, first motor 9, second motor 17, pressure gauge 20 and sound-light alarm 22 are all electrically connected with controller 21;

[0025] When the gas is injected, the corresponding gas pipeline is connected to the gas inlet cylinder 6, and the first motor 9 drives the rotating disc 10 to rotate, so that the gas inlet hole 11 on the rotating disc 10 is completely overlapped with the gas inlet hole 11 on the baffle disc 7, that is, the entire gas inlet valve 4 is in the fully open state, and the gas flow is the largest at this time, so that the required gas is injected into the tank body 1. During the gas injection process, as the total amount of gas injection increases, the pressure in the tank body 1 increases, so that the amount of input gas can be monitored by real-time detection of the pressure in the tank body 1 through the pressure gauge 20, and the corresponding pressure information is fed back to the controller 21, and the controller 21 is pre-set with a plurality of low-to-high pressure set values.
