[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0029] Example 1
[0030] Reference Figure 1-5 , which is the first embodiment of the utility model, provides an automatic metering device for ammonium thiocyanate solution, which comprises a circular box 1, a rotating disk 2 is rotatably mounted on the top of the circular box 1, and a circle of material trough 3 is opened on the top of the rotating disk 2 toward the outside;
[0031] A solution feeding structure 5, the feeding end of the solution feeding structure 5 is fixedly connected to the outlet end of the solution box, the interior of the solution box is provided with an ammonium thiocyanate solution, the solution feeding structure 5 comprises a metering pump 51, the liquid outlet end of the metering pump 51 is fixedly connected to a hose 52, the liquid outlet end of the hose 52 is fixedly connected to a U-shaped feeding pipe 53, the liquid outlet end of the U-shaped feeding pipe 53 is installed with an air blocking structure 56, the liquid inlet end of the U-shaped feeding pipe 53 is welded with a linkage block 55, the bottom of the linkage block 55 is fixedly connected to the movable end of an electric telescopic rod 54;
[0032] An air suction purification structure 4 is installed inside the circular box 1, and the air suction end of the air suction purification structure 4 is located outside the circular box 1. The air suction purification structure 4 has three air suction ends, two of which are located at the outlet end of the solution feeding structure 5, and the other is located at the bottle cap installation position.
[0033] The loading bottle is placed in the inner cavity of the material trough 3, and the rotating disk 2 is driven by the driving motor 8 to rotate, and the loading bottle is rotated to the position just below the discharge end of the solution feeding structure 5. At this time, the driving motor 8 stops, and the electric telescopic rod 54 shortens and drives the linkage block 55 to move downward, so that the discharge end of the U-shaped feeding tube 53 passes through the bottle mouth of the loading bottle and enters the interior of the loading bottle. Then, the metering pump 51 is controlled to pump the ammonium thiocyanate solution and enter the interior of the loading bottle through the hose 52 and the U-shaped feeding tube 53. The metering pump 51 calculates the flow rate passing through and controls the start and stop.
[0034] A driving motor 8 is arranged inside the circular box 1, and the driving end of the driving motor 8 is connected to the bottom end of the rotating disk 2. A circle of universal balls 9 is fixedly installed on the outer edge of the bottom of the rotating disk 2, and the rolling end of the universal balls 9 contacts the upper surface of the circular box 1.
[0035] The air blocking structure 56 includes a fixed ring 561 welded to the outlet end of the U-shaped feeding tube 53. The fixed ring 561 is slidably connected to a T-shaped rod 562 through a sliding hole opened thereon. A lower pressure ring 566 is fixedly connected between the movable ends of the two T-shaped rods 562. A spring 563 is sleeved on the rod end of the T-shaped rod 562. Under the elastic action of the spring 563, the rubber block 565 is tightly pressed against the bottle mouth of the loading bottle.
[0036] A rubber block 565 is bonded to the bottom end of the lower pressure ring 566, and the thickness of the rubber block 565 is one centimeter. The elasticity of the rubber block 565 makes it fit tightly with the bottle mouth of the loading bottle to avoid the existence of a gap.
[0037] When the ammonium thiocyanate solution is loaded into the loading bottle, the rubber block 565 blocks the bottle mouth to prevent the ammonium thiocyanate solution from volatilizing outwards, avoid the toxic gas from leaking outwards, reduce the volatilization amount of the ammonium thiocyanate solution, and avoid the toxic gas from spreading in large quantities in the device area.
[0038] During use, when the discharge end of the U-shaped feeding tube 53 enters the loading bottle, the rubber block 565 is first pressed on the bottle mouth of the loading bottle. As the U-shaped feeding tube 53 continues to descend, the rubber block 565 is subjected to the resistance of the loading bottle and compresses the spring 563. Under the elastic action of the spring 563, the rubber block 565 is tightly pressed against the bottle mouth of the loading bottle. When the ammonium thiocyanate solution is loaded into the loading bottle, the rubber block 565 blocks the bottle mouth to prevent the ammonium thiocyanate solution from volatilizing outward.

[0040] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0041] Guide strips 567 are welded on both sides of the outlet end of the U-shaped feeding tube 53 , and guide grooves 564 matching the guide strips 567 are formed on both sides of the inner wall of the lower pressure ring 566 .
[0042] The air intake purification structure 4 includes a purification bin 41 fixed to the bottom of the inner wall of the circular box 1, and the driving motor 8 is installed on the top of the purification bin 41, and a collecting bin 42 is welded on one side of the outer wall of the circular box 1, and the air outlet end of the collecting bin 42 is fixedly connected to the air intake end of the air pump, and the air outlet end of the air pump is connected to the air inlet end of the tail end of the purification bin 41, and a group of U-shaped air ducts 43 are installed on some of the outer walls of the circular box 1 near the solution feeding structure 5, and the air outlet end of the U-shaped air duct 43 is welded to the air intake end of the collecting bin 42, and an air intake head 44 is fixedly installed at the air intake end of the U-shaped air duct 43 to collect the volatile toxic gases and prevent them from spreading in the air.
[0043] Activated carbon adsorption layers 47 are installed on both sides of the purification chamber 41, and a titanium dioxide photocatalyst layer 45 is fixedly installed inside the purification chamber 41 and in the middle of the activated carbon adsorption layers 47 on both sides. An ultraviolet lamp 46 is installed inside the purification chamber 41 and between the purification chamber 41 and the activated carbon adsorption layer 47. The ultraviolet lamp 46 irradiates the titanium dioxide photocatalyst layer 45, and adsorbs and filters through the two activated carbon adsorption layers 47, and irradiates the titanium dioxide photocatalyst layer 45 through the gas blocking structure 56, catalytically oxidizes the ammonia and thiocyanate gases, converts them into harmless substances, and purifies the toxic gases to prevent them from endangering human health.
[0044] Two welding blocks 7 are welded on the side of the outer wall of the circular box 1 away from the air intake purification structure 4, and a shielding bin 6 is welded between the tops of the two welding blocks 7. Workers use the shielding bin 6 for shielding. A through hole is opened at the end of the vertical plate of the shielding bin 6 for the bottles to pass through.
[0045] During use, when loading is completed, the electric telescopic rod 54 drives the U-shaped loading tube 53 to rise and detach from the inside of the loading bottle, and the driving motor 8 drives the rotating disk 2 to continue to rotate. At this time, the toxic gas evaporates outward, and the air pump pumps and sucks. The suction force passes through the collection bin 42, the U-shaped air duct 43, and the suction head 44, and absorbs the toxic gas emitted in the space, and transports it to the inside of the purification bin 41, and is adsorbed and filtered through two activated carbon adsorption layers 47, and the titanium dioxide photocatalyst layer 45 is irradiated through the gas blocking structure 56, catalytically oxidizing the ammonia and thiocyanate gases, converting them into harmless substances, and purifying the toxic gas.
[0046] The remaining structures are the same as those of Example 1.
[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
