Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate processing, and in particular to a solid-liquid separation device for ammonium perchlorate processing. Background Technology

[0002] Ammonium perchlorate, as a strong oxidizing agent, can be used to make explosives and fireworks, and as an analytical reagent. It can also be used to oxidize aluminum with magnesium, which in turn causes ammonium perchlorate to decompose and produce a large amount of gas for rocket launches. It is also used to manufacture ammonium perchlorate explosives, engraving agents, and artificial hail suppressants. It is widely used in the aerospace industry and people's daily lives.

[0003] For example, a patent entitled "A Recycling Device for Ammonium Perchlorate with a Solid-Liquid Separator" (patent application number: CN202323616903.6) discloses a recycling device for ammonium perchlorate with a solid-liquid separator. It is equipped with a moving separation component, which helps to fully separate the ammonium perchlorate crystals from the filtrate. The moving tube is driven by a hydraulic cylinder to move vertically, so that the filter holes and the feed inlet on the moving tube enter the arc-shaped guide plate in a step-by-step manner. This facilitates the treatment of the filtrate first, and then the remaining ammonium perchlorate crystals are treated centrally. However, the internal structure is complicated, the production cost is high, and it is difficult for personnel to clearly understand the completion of the internal processes.

[0004] Therefore, it is necessary to propose a solid-liquid separation device for ammonium perchlorate processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a solid-liquid separation device for ammonium perchlorate processing, in order to solve the problems of numerous internal structures, high production costs, and difficulty for personnel to clearly understand the completion status of internal processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separation device for ammonium perchlorate processing, comprising:

[0007] Separation tank, the separation tank being used to input ammonium perchlorate crystallization solution;

[0008] A discharge pipe is provided inside the separation tank, with its bottom end extending out of the separation tank;

[0009] A conical hopper, wherein the conical hopper is elastically raised and lowered to fit the outside of the discharge pipe;

[0010] The conical hopper has filter holes for the solution to pass through;

[0011] The discharge pipe has an opening on its outer side for solid particles to enter, and an induction switch is installed inside the opening.

[0012] Preferably, a top cover is installed at the top of the separation tank, an electric push rod is fixed at the bottom of the top cover, and a sealing plug is connected to the bottom of the electric push rod;

[0013] The sealing plug blocks the opening.

[0014] Preferably, the conical opening of the conical bucket is oriented upwards;

[0015] An elastic rope connects the conical bucket and the top cover.

[0016] Preferably, a prompting rod is fixed to the top of the conical bucket, and a through hole is provided on the top cover for the prompting rod to pass through;

[0017] The indicator bar is evenly distributed with at least two colors along its height.

[0018] Preferably, both the indicator rod and the electric push rod are equipped with position sensors corresponding to their positions.

[0019] Preferably, the top of the top cover is provided with a feed inlet, the bottom of the outer side of the separator is provided with a drain outlet, and a filter screen is provided inside the drain outlet.

[0020] Preferably, the bottom of the separation tank is fixed with four support legs.

[0021] The technical effects and advantages of this utility model are as follows:

[0022] 1. In the actual operation of this utility model, when the ammonium perchlorate crystallizing liquid is fed into the separator through the feed port, the liquid material will fall into the conical hopper. The conical hopper will automatically descend under the influence of gravity and drive the liquid down to the bottom of the separator. The liquid will gradually be discharged through the drain port, while the crystal blocks and particles in the liquid will be intercepted by the filter holes and remain inside the conical hopper.

[0023] 2. After all the liquid has been drained, the remaining crystals are lighter. With the pull of the elastic rope, they will move the conical hopper and the collected crystals upwards until the position sensors on the indicator rod and the electric push rod sense each other and transmit the signal to the controller. The controller controls the electric push rod to move the sealing plug upwards, exposing the opening. At this time, the material in the conical hopper enters the opening through the conical slope and is finally discharged from the separator through the discharge pipe, automatically completing the separation of liquid and crystals. When there are no more crystals, the conical hopper rises to its highest point.

[0024] 3. Simultaneously, as the conical bucket rises and falls, it will cause the indicator lever to rise and fall as well. The color displayed by the indicator lever extending from the separator tank indicates that the program inside the separator tank has reached the corresponding stage, which is convenient for personnel to be alerted.

[0030] This utility model provides, for example Figures 1-4 The solid-liquid separation device for ammonium perchlorate processing shown includes: a separation tank 1, which is used to input ammonium perchlorate crystallization solution and serves as the main container for the entire solid-liquid separation process. Four support legs 2 are fixed at the bottom of the separation tank 1 to support the entire device and ensure its stable operation.

[0031] The discharge pipe 3 is located inside the separator 1, with its bottom end extending out of the separator 1. A conical hopper 9 is elastically and vertically fitted to the outside of the discharge pipe 3. An electric push rod 12 is fixed to the bottom of the top cover 4, and a sealing plug 13 is connected to the bottom of the electric push rod 12. An inlet 5 is located at the top of the top cover 4. The conical hopper 9 has filter holes for the solution to pass through. The conical opening of the conical hopper 9 faces upwards; the upward-facing conical opening is used to collect materials.

[0032] In the actual operation of this utility model, when the ammonium perchlorate crystallizing liquid is fed into the separator 1 through the feed port 5, the liquid material will fall into the conical hopper 9. The conical hopper 9 will automatically descend under the influence of gravity and drive the liquid down to the bottom of the separator 1. The liquid will gradually be discharged through the drain port 8, while the crystal blocks and particles in the liquid will be intercepted by the filter holes and remain inside the conical hopper 9.

[0033] An inlet 14 for solid particles to enter is provided on the outside of the discharge pipe 3, and an induction switch is installed inside the inlet 14.

[0034] The top of the separator tank 1 is equipped with a top cover 4, and an elastic rope 10 is connected between the conical hopper 9 and the top cover 4. A drain port 8 is provided at the bottom of the outer side of the separator tank 1, and a sealing plug 13 blocks the opening 14.

[0035] A prompting rod 6 is fixed at the top of the conical bucket 9, and a through hole is provided on the top cover 4 for the prompting rod 6 to pass through. The prompting rod 6 is evenly arranged with at least two colors along the height direction.

[0036] Both the indicator lever 6 and the electric push rod 12 are equipped with position sensors 11 corresponding to their positions.

[0037] After all the liquid is discharged, the remaining crystals are lighter. With the pulling force of the elastic rope 10, they will move the conical hopper 9 and the collected crystals upward until the position sensor 11 on the indicator rod 6 and the electric push rod 12 sense each other and transmit the signal to the controller. The controller controls the electric push rod 12 to drive the sealing plug 13 to rise, exposing the outlet 14. At this time, the material in the conical hopper 9 enters the outlet 14 through the conical slope and is finally discharged from the discharge pipe 3 into the separator 1, automatically completing the separation of liquid and crystals. When there are no more crystals, the conical hopper 9 rises to the highest point.

[0038] At the same time, when the conical bucket 9 rises and falls, it will drive the indicator rod 6 to rise and fall. The color displayed by the part of the indicator rod 6 extending out of the separation tank 1 indicates that the program in the separation tank 1 has reached the corresponding program, which is convenient for reminding personnel.

[0039] For example, when the indicator lever 6 is divided into red and yellow, when both red and yellow are extended, it means that the conical hopper 9 is rising and the material is being discharged. If only the upper part of the red is exposed, it means that the conical hopper 9 is in the process of discharging material.

[0040] A filter screen 7 is installed inside the drain port 8 to prevent some particles from being discharged.
