The adding device includes a storage device and an adjusting device. The storage device is installed on the upper part of the adjusting device. The storage device includes a first adjusting tube, a connecting tube, a storage tank and a first discharge hole. The first discharge hole is opened on one side of the bottom of the first adjusting tube. The storage tank is fixedly installed on the upper end of the first adjusting tube. The connecting tube is fixedly installed in the middle of the upper end surface of the storage tank. The adjusting device includes a second discharge hole, a telescopic spring, a second adjusting tube, a connecting rod and a floating block. The connecting rod is evenly fixedly installed on the upper end surface of the floating block. The second adjusting tube is fixedly installed on the upper end of the connecting rod. The second discharge hole is opened through one side of the bottom end of the second adjusting tube. The telescopic spring is fixedly installed on the upper end of the second adjusting tube.

[0005] Preferably, the telescopic spring is welded inside the first adjusting tube, and the second adjusting tube is slidably and sealingly inserted inside the first adjusting tube.

[0006] Preferably, the floating block is made of plastic, and the interior of the floating block is hollow.

[0007] Preferably, the first discharge hole and the second discharge hole have the same aperture.

[0008] Preferably, the first discharge hole and the second discharge hole are vertically located on the same straight line.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The bottom end of the second regulating tube of the present invention is connected and installed with a float block through a connecting rod. The float block is made of plastic and the inside of the float block is hollow. Therefore, as the liquid level of the liquid ingredients in the mixing tank continues to increase, the float block causes the second regulating tube to squeeze the telescopic spring, thereby causing the telescopic spring to contract and the second regulating tube to rise. The first discharge hole and the second discharge hole are vertically located on the same straight line, thereby achieving alignment of the second discharge hole with the first discharge hole. At this time, the additive stored in the storage tank will flow into the interior of the mixing tank from the first discharge hole, thereby mixing with the ingredients in the mixing tank. The amount of additive added can be controlled and set by controlling the apertures of the first discharge hole and the second discharge hole, so that the amount of additive added can be proportioned and mixed with the ingredients at one time. When the ingredients in the mixing tank are full, the positions of the first discharge hole and the second discharge hole are staggered under the buoyancy of the float block. At this time, the addition of additives is stopped, so that the additives and the ingredients are fully mixed and reacted.

[0015] 2. A pressure relief device is embedded on the sealing plate of the present invention. When the internal pressure of the mixing tank is relatively high, the gas pushes the sealing cover plate to rise, so that there is a gap between the sealing cover plate and the sealing groove, which plays a role in pressure relief. When the pressure inside the mixing tank returns to normal, the sealing cover plate is sealed and clamped in the inside of the sealing groove again under the action of the adjusting spring tension, thereby ensuring that the mixing tank will not explode.

[0024] The telescopic spring 20 is welded inside the first regulating tube 15, and the second regulating tube 21 is slidably sealed and plugged into the inside of the first regulating tube 15. The material of the float 23 is plastic, and the inside of the float 23 is hollow. The apertures of the first discharge hole 18 and the second discharge hole 19 are the same, and the first discharge hole 18 and the second discharge hole 19 are vertically located on the same straight line. The pressure relief ring 9 is embedded in the inside of the sealing plate 4, and the pressure relief hole 10 is connected with the inside of the mixing tank 6. The sealing cover plate 12 of the regulating spring 11 is sealed and clamped in the inside of the sealing groove 8 in the natural state, and the bottom end surface edge of the sealing cover plate 12 is embedded with a sealing rubber ring. The main conveying pipe 1 passes through the sealing plate 4 and is plugged into the inside of the mixing tank 6. The bottom end of the second regulating tube 21 is connected and installed with the float 23 through the connecting rod 22. The material of the float 23 is plastic, and the inside of the float 23 is hollow. Therefore, the float 23 moves with the inside of the mixing tank 6. When the liquid level of the liquid ingredients continues to increase, the float 23 causes the second regulating tube 21 to squeeze the telescopic spring 20, thereby causing the telescopic spring 20 to contract and the second regulating tube 21 to rise. The first discharge hole 18 and the second discharge hole 19 are vertically located on the same straight line, thereby realizing the alignment of the second discharge hole 19 with the first discharge hole 18. At this time, the auxiliary agent stored in the storage tank 17 will flow from the first discharge hole 18 into the interior of the mixing tank 6, thereby mixing with the ingredients inside the mixing tank 6. By controlling the apertures of the first discharge hole 18 and the second discharge hole 19, the amount of auxiliary agent added can be controlled and set, so that the amount of addition can be matched and mixed with the ingredients at one time. When the ingredients inside the mixing tank 6 are full, the positions of the first discharge hole 18 and the second discharge hole 19 are staggered under the buoyancy of the float 23. At this time, the addition of auxiliary agent is stopped, so that the auxiliary agent and the ingredients are fully mixed and reacted.

[0025] Working principle: the ingredients can be transported to the interior of the mixing tank 6 through the main conveying pipe 1, and the bottom end of the new second regulating pipe 21 is connected to a float 23 through a connecting rod 22. The material of the float 23 is plastic, and the interior of the float 23 is hollow. Therefore, as the liquid level of the liquid ingredients in the mixing tank 6 continues to increase, the float 23 causes the second regulating pipe 21 to squeeze the telescopic spring 20, thereby causing the telescopic spring 20 to contract and the second regulating pipe 21 to rise. The first discharge hole 18 and the second discharge hole 19 are vertically located on the same straight line, thereby achieving alignment of the second discharge hole 19 with the first discharge hole 18. At this time, the additive stored in the storage tank 17 will flow from the first discharge hole 18 into the interior of the mixing tank 6, thereby mixing with the ingredients in the mixing tank 6. The amount of additive added can be controlled and set by controlling the apertures of the first discharge hole 18 and the second discharge hole 19. The valve body 5 is opened to discharge the mixed liquid through the delivery pipe 5. When the ingredients in the mixing tank 6 are full, the first discharge hole 18 and the second discharge hole 19 are staggered under the buoyancy of the floating block 23. At this time, the addition of the auxiliary agent is stopped to ensure sufficient mixing and reaction between the auxiliary agent and the ingredients. The pressure relief device 2 is embedded in the sealing plate 4. When the internal pressure of the mixing tank 6 is large, the gas pushes the sealing cover plate 12 to rise, so that there is a gap between the sealing cover plate 12 and the sealing groove 8, which plays a role in pressure relief. When the pressure inside the mixing tank 6 returns to normal, the sealing cover plate 12 is sealed and clamped in the sealing groove 8 again under the tension of the adjusting spring 11, thereby ensuring that the mixing tank 6 will not explode. The auxiliary agent can be adjusted quickly and conveniently during use of the present invention, and it is safe and will not explode when the ingredients are mixed with the auxiliary agent.
