Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate production, and in particular to a mobile quantitative feeding device for ammonium perchlorate production. Background Technology

[0002] Ammonium perchlorate is an inorganic compound, a white crystalline powder, and is hygroscopic. It is a strong oxidizing agent and will explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. Contact with strong acids poses a risk of combustion and explosion. It is used in the manufacture of explosives and fireworks, and as an analytical reagent.

[0003] For example, a patent entitled "A Quantitative Feeding Device for Ammonium Perchlorate Production" (patent application number: 202222523154.1) discloses a quantitative feeding device for ammonium perchlorate production. Through a pneumatic pusher, a moving plate can be driven to move left and right, alternately causing two container components to discharge and load materials. By using the two container components alternately, no extra time is needed to wait for reloading after a single discharge, improving the continuity of the discharge and thus increasing the efficiency of the equipment. However, since ammonium perchlorate is in powder form, after the container components are fed, the powder tends to stick to the inside of the container components and is not easy to discharge. If used continuously, the residual powder will affect the accuracy of the next discharge.

[0004] Therefore, it is necessary to propose a mobile quantitative feeding device for the production of ammonium perchlorate to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mobile quantitative feeding device for the production of ammonium perchlorate, in order to solve the problem in the prior art where, since ammonium perchlorate is in powder form, the powder tends to adhere to the inside of the container after feeding, making it difficult to discharge. If used continuously, the remaining powder will affect the accuracy of the next feeding.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mobile quantitative feeding device for the production of ammonium perchlorate, comprising a support frame, two quantitative cylinders fixed on one side of the support frame, a bottom plate hinged to the bottom of each quantitative cylinder, a fixed frame above the two quantitative cylinders, a sliding plate movably disposed within the fixed frame, a filling cylinder fixed to the top of the sliding plate, and an opening on the sliding plate corresponding to the bottom of the filling cylinder;

[0007] A connecting frame is fixed to one side of the bottom of the sliding plate, and a shovel plate is fixed to the bottom of the connecting frame. The shovel plate is attached to the bottom of the corresponding base plate. Two springs are fixed to the side of the connecting frame near the metering cylinder, and a striking ball is fixed to the end of each spring.

[0008] Preferably, the two striking balls are located on both sides of the corresponding filling cylinder, and a solenoid valve is provided in the inlet.

[0009] Preferably, slide rails are fixed on both sides inside the fixed frame, and a lead screw is rotatably connected between the two ends inside the fixed frame. A sliding plate is threaded onto the outside of the lead screw, and the sliding plate is slidably engaged on the two slide rails.

[0010] Preferably, auxiliary blocks are fixed on both sides of the sliding plate, and a fan is embedded in the bottom of each of the two auxiliary blocks.

[0011] Preferably, the hinge joints of the two base plates and the corresponding metering cylinders are arranged opposite each other.

[0012] Preferably, a drive motor is fixed to one side of the fixed frame, and the drive shaft of the drive motor is fixedly connected to one end of the lead screw.

[0013] Preferably, both sides of the shovel are provided with pointed ends.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the actual operation of this utility model, when the top of the filling cylinder and the corresponding metering cylinder are aligned by the sliding plate, the sliding plate simultaneously drives the shovel plate to block the bottom plate of the metering cylinder, so as to prevent the bottom plate and the metering cylinder from separating during metering. After the metering cylinder is filled, it can be moved to another metering cylinder by moving the sliding plate, so as to perform alternating filling and improve feeding efficiency.

[0016] 2. When the sliding plate leaves the first metering cylinder, the bottom plate and the shovel plate disengage, and the powder inside the metering cylinder automatically descends, completing the feeding of one metering cylinder volume. Furthermore, as the sliding plate moves, the striking ball, which is fixed at the end of the spring, will strike and collide with the outside of the metering cylinder during feeding. The resulting vibration can accelerate the descent of the ammonium perchlorate powder adhering to the inner wall of the metering cylinder, preventing it from remaining inside the metering cylinder and affecting the accuracy of feeding.

[0017] 3. Auxiliary blocks are fixed on both sides of the sliding plate. A fan is embedded in the bottom of each auxiliary block. When the sliding plate moves, the auxiliary blocks will move to the top of the metering cylinder in the feeding process. The fan inside the auxiliary block will start, and the air force can accelerate the discharge of ammonium perchlorate powder inside the metering cylinder, further improving the cleanliness inside the metering cylinder. At the same time, the top of the auxiliary block will rub against the top of the metering cylinder, thereby pushing away the ammonium perchlorate powder left on the top of the metering cylinder.

[0022] This utility model provides, for example Figures 1-3 The mobile quantitative feeding device for the production of ammonium perchlorate shown includes a support frame 1, with two quantitative cylinders 12 fixed on one side of the support frame 1. The support frame 1 can provide fixed support for the sides of the two quantitative cylinders 12.

[0023] Both quantitative cylinders 12 are hinged to a base plate 13 at their bottom ends. A fixed frame 2 is provided above the two quantitative cylinders 12. A sliding plate 7 is movably arranged inside the fixed frame 2. A filling cylinder 6 is fixed at the top of the sliding plate 7. An opening is provided on the sliding plate 7 that corresponds to the bottom end of the filling cylinder 6, and a solenoid valve is provided inside the opening.

[0024] When the sliding plate 7 moves within the fixed frame 2, the position of the inlet can be aligned with the top of the two metering cylinders 12 respectively. Once the positions are aligned, the ammonium perchlorate powder inside the filling cylinder 6 can be poured into the corresponding metering cylinder 12 by opening the solenoid valve.

[0025] Specifically, slide rails 3 are fixed on both sides inside the fixed frame 2. A lead screw 4 is rotatably connected between the two ends inside the fixed frame 2. A sliding plate 7 is threaded on the outside of the lead screw 4 and slides on the two slide rails 3. A drive motor 5 is fixed on one side of the fixed frame 2. The drive shaft of the drive motor 5 is fixedly connected to one end of the lead screw 4. The drive motor 5 can drive the lead screw 4 to rotate through the drive shaft. The drive motor 5 can be used as a drive component to move the sliding plate 7.

[0026] In the actual operation of this utility model, when the drive motor 5 is started, it drives the lead screw 4 to rotate in both directions. At this time, the sliding plate 7 will move back and forth along the length direction of the lead screw 4, and the two slide rails 3 can maintain the stability of the sliding plate 7 when it moves.

[0027] A connecting frame 8 is fixed to one side of the bottom of the sliding plate 7. A shovel plate 11 is fixed to the bottom of the connecting frame 8. The shovel plate 11 is attached to the bottom of the corresponding bottom plate 13. Two springs 9 are fixed to the side of the connecting frame 8 near the metering cylinder 12. A striking ball 10 is fixed to the end of each of the two springs 9. The two striking balls 10 are located on both sides of the corresponding filling cylinder 6.

[0028] In the actual operation of this utility model, when the sliding plate 7 drives the top of the filling cylinder 6 and the corresponding metering cylinder 12 to align, the sliding plate 7 simultaneously drives the shovel plate 11 to block the bottom plate 13 at the bottom of the metering cylinder 12, so as to prevent the bottom plate 13 from separating from the metering cylinder 12 during metering. After the metering cylinder 12 has finished filling, it can be moved to another metering cylinder 12 by moving the sliding plate 7, so as to perform alternating filling and improve feeding efficiency.

[0029] Furthermore, when the sliding plate 7 leaves the first metering cylinder 12, the bottom plate 13 and the shovel plate 11 disengage, and the powder inside the metering cylinder 12 automatically descends, completing the feeding of one metering cylinder 12 volume. In addition, when the sliding plate 7 moves, the striking ball 10, which is fixed at the end of the spring 9, will strike and collide with the outside of the metering cylinder 12 during feeding. The resulting vibration can accelerate the descent of the ammonium perchlorate powder adhering to the inner wall of the metering cylinder 12, avoiding it from being left inside the metering cylinder 12 and affecting the accuracy of feeding.

[0030] Auxiliary blocks 14 are fixed on both sides of the sliding plate 7. A fan is embedded in the bottom of each of the two auxiliary blocks 14. When the sliding plate 7 moves, the auxiliary blocks 14 will move above the metering cylinder 12 in the feeding process. The fan in the auxiliary block 14 will start, and the air force can accelerate the discharge of ammonium perchlorate powder inside the metering cylinder 12, further improving the cleanliness of the inside of the metering cylinder 12.

[0031] At the same time, the top of the auxiliary block 14 will rub against the top of the metering cylinder 12, thereby pushing away the ammonium perchlorate powder left on the top of the metering cylinder 12.

[0032] The hinge joints of the two base plates 13 and the corresponding metering cylinders 12 are arranged opposite each other, which facilitates the two-stage scooping up of the base plates 13 by the shovel plate 11.

[0033] Both sides of the shovel plate 11 are equipped with sharp points.
