[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 4 As shown, the ammonium perchlorate quantitative feeding processing equipment of this embodiment includes a box body 1. A material cylinder 8 is arranged on the top of the box body 1, and two material cylinders 8 are symmetrically arranged on the left and right sides. The two material cylinders 8 are respectively used to hold two solutions for producing ammonium perchlorate: perchloric acid and ammonia. A quantitative mechanism is provided between the two material cylinders 8 and the box body 1 to ensure a fixed mixing ratio of the two solutions. Each of the two material cylinders 8 has a feed inlet 9 on its upper surface. A first filter screen 12 is connected inside each of the two material cylinders 8. The first filter screen 12 filters impurities when the solution is discharged from the inside of the material cylinder 8. A stirring rod 15 is installed on the inner wall of the left end of the box body 1. The stirring of the stirring rod 15 makes the ammonium perchlorate solution more soluble and soluble. Chloric acid and ammonia are fully mixed and reacted inside the tank 1. A sealing mechanism is provided on the right side of the stirring rod 15. Through the sealing mechanism, an independent space can be separated inside the tank 1 during the mixing process, so as to facilitate the filtration of the solution in the settling and cooling pot after mixing, so as to separate the ammonium perchlorate crystals from the mother liquor. A second filter screen 17 is provided on the right side of the sealing mechanism. After the sealing mechanism is removed, the crystals can be filtered by the fluidity of the solution itself and the second filter screen 17. A treatment mechanism is provided above the second filter screen 17. The ammonia gas generated during the reaction can be absorbed and treated by the treatment mechanism. An outlet 22 is opened at the bottom right end of the tank 1.

[0023] Specifically, the quantitative mechanism includes a housing 2, a first lead screw 4, and connecting blocks 5. The lower surface of the housing 2 is connected to the box 1. The first lead screw 4 is installed inside the housing 2. Multiple connecting blocks 5 are sleeved on the outer surface of the first lead screw 4. Two connecting pipes 7 are symmetrically arranged on the upper surface of the housing 2, and the two connecting pipes 7 are respectively connected to two material cylinders 8. The first lead screw 4 is composed of four sub-rods. The surface threads of adjacent sub-rods are opposite, and each sub-rod surface is connected to a connecting block 5. When the first lead screw 4 is driven to rotate by the motor, the four connecting blocks 5 will automatically slide at the same speed, and the sliding directions of two adjacent connecting blocks 5 are opposite. This seals and opens the connection between the housing 2 and the two material cylinders 8. When opening, since the sliding speed of the connecting blocks 5 is the same, the two spaces created below the two connection ports have the same volume, so that the discharge volume of the two solutions can be fixed at a 1:1 ratio.

[0024] Furthermore, a transparent window 3 is installed on the front surface of the outer shell 2, and a scale is set below the transparent window 3. A protruding rod 6 is connected to the top outer surface of the connecting block 5. Through the transparent window 3, the staff can see the internal situation of the outer shell 2 from the outside, and then, in conjunction with the scale, they can know the volume of the space created by the connecting block 5. The two connecting blocks 5 located on the inner side of the outer shell 2 are provided with protruding rods 6 on their facing surfaces. When the two blocks slide to create space, they will contact the middle inner wall of the outer shell 2. Two pressure sensors are installed on both sides of the middle inner wall. The pressure sensors are sensed by the pressure of the protruding rods 6, and the pressure signal generation time is detected. By comparing the two sets of pressure data, it can be determined whether there is an error in the sliding distance of the two connecting blocks 5. The model of the pressure sensor is selected according to actual needs.

[0025] Furthermore, the outer surfaces of the two material cylinders 8 are connected to a fixing ring 10, and the left and right ends of the fixing ring 10 are respectively connected to a support rod 11, so that the two material cylinders 8 are stably supported by the fixing ring 10 and the support rod 11.

[0026] Furthermore, a door 13 is connected to the front surface of the chamber 1. A pressure sensor 14 is installed on the outer surface of the door 13, and the input end of the pressure sensor 14 extends into the interior of the chamber 1. By opening the door 13, the ammonium perchlorate crystals filtered out inside the chamber 1 can be removed. The pressure sensor 14 can be used to know the change in internal pressure of the chamber 1, thereby knowing the amount of ammonia produced. The pressure sensor 14 is an existing product, and its model is selected according to actual needs.

[0027] Furthermore, the sealing mechanism includes a baffle 16 and a second lead screw 18. The baffle 16 is located inside the housing 1, and the top of the baffle 16 extends through to the outside of the housing 1 and is connected to the second lead screw 18. The top of the second lead screw 18 is connected to a motor. By driving the second lead screw 18 to rotate through the motor, the baffle 16 can slide up and down, thereby blocking the solution inside the housing 1 or allowing it to flow and contact the second filter screen 17.

[0028] Furthermore, the processing mechanism includes a chamber 19, a delivery pipe 20, and a suction pipe 21. The chamber 19 is located at the top right end of the housing 1. The delivery pipe 20 is inserted inside the chamber 19. The top end of the delivery pipe 20 is connected to the suction pipe 21 via an air pump. The bottom end of the suction pipe 21 extends into the interior of the housing 1. By starting the air pump, the interior of the housing 1 is drawn out through the suction pipe 21 and transported to the interior of the chamber 19 through the delivery pipe 20. The chamber 19 is pre-filled with clean water, and ammonia is dissolved in the water for treatment.

[0029] The method of use in this embodiment is as follows: Perchloric acid solution and ammonia water are respectively loaded into the two material cylinders 8. Then, by starting the motor connected to the end of the first lead screw 4, the first lead screw 4 is rotated, thereby creating two spaces of the same volume inside the outer shell 2. By loading the two solutions into the two spaces, the solution ratio is ensured to be one to one. At this time, by closing the valve on the connecting pipe 7, the valves on the two connecting pipes between the outer shell 2 and the box 1 are opened to discharge the two solutions into the box 1, and the mixed solution is stirred. After stirring, it is allowed to stand and cool. After cooling, the second lead screw 18 is rotated to make the baffle 16 rise. The solution flows on its own and comes into contact with the second filter screen 17, thereby separating the crystals from the mother liquor. Finally, the crystals are taken out.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
