[0016] See Figure 1-3 .

[0017] The refrigeration mechanism operates on the same principle as air conditioners and refrigerators, and is a common existing technology. Its specific structure will not be described in detail.

[0018] This utility model discloses a needle-type potassium perchlorate precipitation filtration device, including a precipitation box 1, a first cooling precipitation screen 2, and a second cooling precipitation screen 3. The main body of the precipitation box is a square box structure. Multiple first and second cooling precipitation screens are vertically arranged inside the precipitation box. The first and second cooling precipitation screens are horizontally inserted from a first insertion port 4 and a second insertion port 5 on one side, and are arranged alternately. The surfaces of both the first and second cooling precipitation screens are arc-shaped, with the convex surface of the first cooling precipitation screen facing upwards and the concave surface of the second cooling precipitation screen facing upwards. A residual liquid outlet 6 is provided on one side of the bottom of the precipitation box, and a liquid inlet 7 is provided in the middle of the top of the precipitation box. The solution is poured into the liquid inlet 7, and the solution sequentially passes through multiple layers of cooling precipitation screens for multi-level precipitation and crystallization.

The baffles of the first and second cooling precipitation screen plates are respectively matched with the first and second insertion ports. Larger first and second insertion ports allow for easy removal of the first and second cooling precipitation screen plates when a large amount of crystals are attached to them. The baffles 10 can seal the openings and prevent the solution from flowing outwards when the solution is introduced through the inlet 7.

[0021] A drain groove 11 is provided at the lowest center of the second cooling precipitation screen plate, and drain grooves 11 are provided at the lowest ends of both sides of the first cooling precipitation screen plate. When there are too many crystals on the first cooling precipitation screen plate 2 and the second cooling precipitation screen plate, and the solution cannot drain out, it can leak from the drain groove 11 into the next tank.

A refrigeration chamber 13 is installed above the refrigerator. The evaporator coil 14 of the refrigerator is installed inside the refrigeration chamber. The plate on which the refrigeration chamber and the precipitation chamber are attached is a metal plate. Insulation cotton is installed on the five outer sides of the refrigeration chamber. The refrigerator 12 cools the inside of the chamber to maintain an optimal precipitation temperature.
