[0018] Furthermore, a method for preparing an electronic-grade ammonia preparation device comprises the following steps:

[0019] S1: By providing a universal wheel at the lower corner of the base, the device can be easily moved. After the device is moved to a suitable position, the motor 1 is turned on. The motor 1 drives the bidirectional screw 1 to rotate through the output end. The rotation of the bidirectional screw 1 drives the two sets of nut blocks to approach each other. The two sets of nut blocks approach each other and drive the two sets of hinge seats 2 to approach each other. The two sets of hinge seats 2 approach each other and drive the angles of the two sets of support rods to increase, thereby cooperating with the hinge seat 1 to drive the lifting plate to descend. The descent of the lifting plate drives the support seat to descend to contact with the ground, thereby increasing the contact area between the device and the ground to ensure the stability of the device when in use. When the lifting plate is lifted, it drives the slider to slide inside the slide slot, thereby improving the stability of the lifting plate during the lifting process. The rotation of the bidirectional screw 1 drives the gear 1 to rotate. The rotation of the gear 1 drives the flexible toothed belt to rotate. The rotation of the flexible toothed belt drives the gear 2 to rotate. The rotation of the gear 2 drives the bidirectional screw 2 to rotate, thereby driving the other two sets of nut blocks to approach each other, thereby improving the stability of the lifting plate during the lifting process.

[0020] S2: Flange 1 and flange 2 are fixedly connected by bolts. At this time, the raw material is passed through the inside of the feed pipe, and ultrapure water is injected into the upper tank body and the lower tank body. Then, hot steam is injected into the steam bin through the steam inlet pipe and finally discharged through the steam outlet hole, so that the hot steam can be mixed with the raw material and ultrapure water. At this time, motor 2 is turned on. Motor 2 drives the stirring shaft to rotate through the output end, and the rotation of the stirring shaft drives the stirring blade to rotate, thereby realizing the production of ammonia. After the ammonia is produced, the ammonia is injected into the inside of the filter box through the air inlet pipe. After the ammonia is filtered, it enters the inside of the lower tank body. The rotation of the stirring shaft drives the second stirring component to rotate, thereby mixing the filtered ammonia with ultrapure water, thereby forming high-quality ammonia water. When the stirring shaft rotates, it drives the cross mounting seat to rotate, and the rotation of the cross mounting seat drives the stirring rod to rotate. The rotation of the stirring rod generates centrifugal force, thereby driving the spring 1 to stretch. When the stirring rod slides outward, it drives the limit block to slide inside the limit groove, thereby improving the stability of the sliding process of the stirring rod;

[0021] S3: When filtering ammonia, insert the mounting seat, magnetic filter plate and activated carbon filter plate into the filter box. Before inserting the mounting seat into the filter box, pull the handle, the handle pulls the pull rod, the pull rod pulls the limit plate and the fixing rod, and drives the second spring to compress. When the mounting seat is inserted into the filter box, release the handle, the second spring rebounds, and drives the fixing rod to insert into the fixing hole, thereby realizing the installation and fixation of the filter plate. At this time, the ammonia can be filtered through the filter plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with a moving mechanism, which can facilitate the movement of the device. When the device is moved to a suitable position, the support base can be driven by a motor to descend to contact the ground, thereby increasing the contact area between the device and the ground, thereby improving the stability of the device and avoiding too many pipelines in the device, which affects the transportation and is inconvenient to disassemble.

[0024] 2. The present invention is provided with a stirring mechanism, which can stir the raw materials and ultrapure water, thereby improving the stirring efficiency of the raw materials and ultrapure water. Through the setting of the second stirring component, the filtered ammonia gas and ultrapure water can be mixed to form formed ammonia water.

[0025] 3. The present invention is provided with an ammonia filtering mechanism, which can facilitate filtering and purifying ammonia. By providing a filter plate fixing assembly, the filter plate can be easily disassembled, thereby improving the use effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

The two sets of nut blocks 98 approach each other to drive the two sets of hinge seats 95 to approach each other. The two sets of hinge seats 95 approach each other to drive the angles of the two sets of support rods 94 to increase, thereby cooperating with the hinge seat 92 to drive the lifting plate 93 to descend. The lifting plate 93 descends and drives the support seat 91 to descend to the ground. When the lifting plate 93 is lifted or lowered, the slider 911 is driven to slide inside the slide groove 910, thereby improving the stability of the lifting plate 93 during the lifting process. The rotation of the bidirectional screw 96 drives the gear 1 991 to rotate, and the rotation of the gear 1 991 drives the flexible toothed belt 994 to rotate, and the rotation of the flexible toothed belt 994 drives the gear 2 993 to rotate, and the rotation of the gear 2 993 drives the bidirectional screw 2 992 to rotate, thereby driving the other two groups of nut blocks 98 to approach each other, thereby improving the stability of the lifting plate 93 during the lifting process.

[0060] S2: The flange 1 81 and the flange 2 87 are fixedly connected by bolts 86. At this time, the raw material is passed through the inside of the feed pipe 10, and then ultrapure water is injected into the upper tank body 11 and the lower tank body 15. Then, hot steam is injected into the steam bin 17 through the steam inlet pipe 12 and finally discharged through the steam outlet 16, so that the hot steam can be mixed with the raw material and ultrapure water. At this time, the motor 2 85 is turned on. The motor 2 85 drives the stirring shaft 84 to rotate through the output end. The rotation of the stirring shaft 84 drives the stirring blade 83 to rotate, thereby realizing the production of ammonia. After the ammonia production is completed, the ammonia is injected into the steam bin 17 through the air inlet pipe 5. The ammonia enters the interior of the filter box 4, and after being filtered, the ammonia enters the interior of the lower tank body 15. The stirring shaft 84 rotates to drive the second stirring component 82 to rotate, so as to mix the filtered ammonia with ultrapure water, thereby forming high-quality ammonia water. When the stirring shaft 84 rotates, it will drive the cross mounting seat 821 to rotate, and the rotation of the cross mounting seat 821 will drive the stirring rod 823 to rotate. The rotation of the stirring rod 823 will generate centrifugal force, thereby driving the spring 1 825 to stretch. When the stirring rod 823 slides outward, it will drive the limit block 824 to slide inside the limit groove 822, thereby improving the stability of the sliding process of the stirring rod 823;

[0061] S3: When filtering ammonia, the mounting seat 31, the magnetic filter plate 34 and the activated carbon filter plate 38 are inserted into the interior of the filter box 4.

At this time, the ammonia can be filtered through the filter plate.

After the device is moved to a suitable position, the motor 97 is turned on, and the motor 97 drives the bidirectional screw rod 96 to rotate through the output end. The rotation of the bidirectional screw rod 96 drives the two groups of nut blocks 98 to approach each other. The two groups of nut blocks 98 approach each other to drive the two groups of hinge seats 95 to approach each other. The two groups of hinge seats 95 approach each other to drive the angles of the two groups of support rods 94 to increase, thereby cooperating with the hinge seat 92 to drive the lifting plate 93 to descend, and the lifting plate 93 descends. The support seat 91 is driven down to contact with the ground, thereby increasing the contact area between the device and the ground to ensure the stability of the device when in use. When the lifting plate 93 is lifted or lowered, the slider 911 is driven to slide inside the slide groove 910, thereby improving the stability of the lifting plate 93 during the lifting process.

After the ammonia production is completed, the ammonia is fed into the steam bin 17 through the steam inlet pipe 12. The air pipe 5 is injected into the interior of the filter box 4, and the ammonia enters the interior of the lower tank 15 after being filtered. The stirring shaft 84 rotates to drive the second stirring component 82 to rotate, so as to mix the filtered ammonia with ultrapure water, thereby forming high-quality ammonia water. When the stirring shaft 84 rotates, it will drive the cross mounting seat 821 to rotate, and the rotation of the cross mounting seat 821 will drive the stirring rod 823 to rotate. The rotation of the stirring rod 823 will generate centrifugal force, thereby driving the spring 1 825 to stretch.
