The second driving shaft 712 is horizontally and slidably connected with a limiting block 75, and a second guiding inclined plane 751 is formed on the side wall of the limiting block 75 away from the floating block 74. The extension spring 76 for driving the limiting block 75 to slide towards the inside of the second driving shaft 712 is arranged in the limiting block 75, the outer side wall of the second driving shaft 712 is connected with the third sealing plate 77 in a sliding mode, the third sealing plate 77 is located in the water storage tank 8, the third sealing plate 77 can cover the air inlet pipe 67, and the locking groove 771 is formed in the third sealing plate 77.
The third sealing plate 77 covers the air inlet pipe 67 to enable the cooling water to be stored in the water storage tank 8, the floating block 74 moves upwards in the cooling water under the buoyancy, and the first guiding inclined surface 741 presses the limiting block 75 to enable the limiting block 75 to move towards the outside of the second driving shaft 712 against the resistance of the stretching spring 76. When the pressure inside the tank body 1 decreases, air enters the air inlet pipe 67, and the air in the air inlet pipe 67 extrudes the second sealing plate 72 to move away from the air cylinder 71, so that the second sealing plate 72 is separated from the first limiting ring 631, and therefore, the air in the air inlet pipe 67 sequentially enters the tank body 1 through the second air conveying pipe 63, the air guide pipe 65 and the first air conveying pipe 6.
The second sealing plate 72 moves to move the first driving shaft 711 away from the cylinder 71, and the second driving shaft 712 moves close to the cylinder 71 in order to maintain the pressure inside the cylinder 71. The second driving shaft 712 drives the stopper 75 to move downward, at this time, the second guiding inclined surface 751 abuts against the third sealing plate 77, the stopper 75 continues to move downward, and the third sealing plate 77 presses the stopper 75 to move toward the inside of the second driving shaft 712 through the second guiding inclined surface 751. When the stopper 75 moves down to the locking groove 771, the stopper 75 is disengaged from the locking of the third sealing plate 77, and the stopper 75 moves outside the second driving shaft 712 into the locking groove 771, thereby fixing the third sealing plate 77 to the second driving shaft 712.
When the pressure inside the tank 1 is recovered, the return spring 73 drives the first driving shaft 711 to move close to the air cylinder 71, so that the second driving shaft 712 moves away from the air cylinder 71, the second driving shaft 712 drives the third sealing plate 77 to move upwards through the limiting block 75 to be separated from the air inlet pipe 67, and cooling water in the water storage tank 8 falls to the air inlet pipe 67 to wash the filter screen 68. After the flushing, the floating block 74 lacks the buoyancy provided by the cooling water and therefore makes free falling movement, so that the first guide inclined plane 741 is separated from the limiting block 75, the tension spring 76 drives the limiting block 75 to move towards the inside of the second driving shaft 712 and separate from the locking groove 771, the second driving shaft 712 is kept still, the third sealing plate 77 is separated from the limiting block 75 and moves downwards to reset to cover the air inlet pipe 67, and the water storage tank 8 can store the cooling water again.
By reducing the pressure inside the tank body 1, air enters the air inlet pipe 67 to drive the second driving shaft 712 to move downwards, the floating block 74 fixes the third sealing plate 77 by using the buoyancy of cooling water, and the third sealing plate 77 is separated from the air inlet pipe 67 after the pressure inside the tank body 1 is recovered, so that the function of flushing the filter screen 68 by cooling water in the water storage tank 8 is realized. The tank body 1 can be used for adjusting the internal pressure to reduce the probability of the tank body 1 being damaged by pressure, and meanwhile, the cooling water can be used for flushing the filter screen 68, so that the filtering efficiency of the filter screen 68 is improved, and the storage of urea solution is facilitated.
The implementation principle of the urea solution storage tank provided by the embodiment of the invention is as follows: when the temperature rises, ammonia in the tank body 1 enters the gas delivery valve 3, so that the first sealing plate 221 is separated from the water inlet pipe 21, cooling water is conveyed to the water storage tank 2 and the cooling cover 4, and the cooling cover 4 is unfolded to cover the tank body 1 to cool the inside of the tank body 1. The redundant ammonia in the tank body 1 sequentially enters the water storage tank 2 through the first air pipe 6, the second air pipe 63, the third air pipe 632 and the waterproof breathable film 64, and the ammonia is absorbed by the cooling water. When the external temperature is reduced and the urea solution in the tank body 1 is output, external air sequentially enters the tank body 1 through the air inlet pipe 67, the second air conveying pipe 63 and the air guide pipe 65, and the pressure in the tank body 1 is regulated. The second driving shaft 712 drives the third sealing plate 77 to be separated from the air inlet pipe 67 through the limiting block 75, and cooling water in the water storage tank 8 enters the air inlet pipe 67 to wash the filter screen 68.
In a second aspect, an embodiment of the present invention provides a method for using a urea solution storage tank, including a urea solution storage tank in the first aspect, where the method for using the urea solution storage tank is as follows:
s1, paving a cooling cover 4: the air temperature rises, ammonia gas in the tank body 1 enters the air delivery valve 3, so that the first sealing plate 221 is separated from the water inlet pipe 21, cooling water is conveyed to the water storage tank 2 and the cooling cover 4, and the cooling cover 4 is unfolded to cover the tank body 1;
s2, absorbing redundant ammonia: ammonia in the tank body 1 sequentially enters the water storage tank 2 through the first air pipe 6, the second air pipe 63, the third air pipe 632 and the waterproof breathable film 64, and the ammonia is absorbed by cooling water;
s3, improving the pressure in the tank body 1: outside air sequentially enters the tank body 1 through the air inlet pipe 67, the second air conveying pipe 63 and the air guide pipe 65, and the pressure intensity in the tank body 1 is regulated;
s4, flushing the filter screen 68: the second driving shaft 712 drives the third sealing plate 77 to be separated from the air inlet pipe 67 through the limiting block 75, and cooling water in the water storage tank 8 enters the air inlet pipe 67 to wash the filter screen 68.
