[0009] The filter cotton layer divides the interior of the impurity removal discharge pipe into a pre-filtration chamber and a post-filtration chamber. The post-filtration chamber is connected to the upper end of the solution discharge pipe and the backwash pipe, and the pre-filtration chamber is connected to the upper end of the impurity removal pipe.

[0010] Preferably, a fixed baffle is provided at the upper end of the pre-filtration chamber. The fixed baffle is fixed on the inner wall of the impurity removal discharge pipe, and the end of the fixed baffle away from the inner wall of the impurity removal discharge pipe is inclined downward. An entry channel is left between the fixed baffle and the filter cotton layer, and the entry channel allows the ammonium perchlorate raw material solution and metal impurities to enter the pre-filtration chamber.

[0011] Preferably, the impurity removal pipe, the solution discharge pipe, and the backwash pipe are respectively equipped with a first solenoid valve, a second solenoid valve, and a third solenoid valve.

[0012] Preferably, a movable baffle is fixedly provided at the upper end of the filter cotton layer. The movable baffle is arranged at an angle, and the end of the movable baffle near the fixed baffle is inclined downward.

[0013] Preferably, the first flange connecting plate and the second flange connecting plate are fixed together by screws and nuts, and the connection is kept sealed.

[0014] Preferably, when air is blown into the post-filter chamber through the backwash pipe, the gas passes through the filter cotton layer and blows below the movable baffle. The movable baffle flips up and fits against the lower surface of the fixed baffle, thus sealing the entry channel.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This impurity removal system can not only filter and remove metal impurities in ammonium perchlorate raw material solution, but also has convenient self-cleaning, eliminating the need for frequent manual cleaning and improving processing efficiency.

[0017] 2. When the third solenoid valve is opened, air can be blown into the filter chamber through the backwash pipe. The air backwashes the filter cotton layer and blows the metal impurities remaining in the impurity removal discharge pipe and on the surface of the filter cotton layer to the impurity removal pipe for discharge, thus achieving the purpose of backwash cleaning without the need for frequent manual cleaning.

[0018] 3. When air is blown into the filter chamber through the backwash pipe, the gas passes through the filter cotton layer and blows below the movable baffle.

[0024] This utility model provides, for example Figures 1-4 The present invention discloses a purification system for processing ammonium perchlorate raw materials. This purification system can not only filter and remove metal impurities in the ammonium perchlorate raw material solution, but also has convenient self-cleaning, eliminating the need for frequent manual cleaning and improving processing efficiency.

[0025] refer to Figure 1 As shown, a purification and discharge mechanism 2 is provided at the bottom of the reactor 1. The reactor 1 is used to store the ammonium perchlorate raw material solution, and the purification and discharge mechanism 2 is used to discharge the ammonium perchlorate raw material solution.

[0026] refer to Figure 2 As shown, the impurity removal and discharge mechanism 2 includes an impurity removal and discharge pipe 3, a first flange connecting plate 4, a second flange connecting plate 5, an impurity removal pipe 6, a solution discharge pipe 7, and a backwash pipe 8. The impurity removal and discharge pipe 3 is connected to the bottom of the reactor 1. The first flange connecting plate 4 is fixedly connected to the bottom of the impurity removal and discharge pipe 3. The first flange connecting plate 4 and the second flange connecting plate 5 are fixed together by screws and nuts. The impurity removal pipe 6, the solution discharge pipe 7, and the backwash pipe 8 are all set on the second flange connecting plate 5, and the impurity removal pipe 6, the solution discharge pipe 7, and the backwash pipe 8 are all connected to the interior of the impurity removal and discharge pipe 3.

[0027] Among them, the impurity removal pipe 6 is used to remove metal impurities from the ammonium perchlorate raw material solution, the solution discharge pipe 7 is used to discharge the ammonium perchlorate raw material solution, and the backwash pipe 8 is used to connect with an external air pump to achieve the purpose of airflow backwashing, so that the metal impurities remaining in the impurity removal discharge pipe 3 can continue to be discharged from the impurity removal pipe 6.

[0028] refer to Figure 3As shown, a filter cotton layer 11 is installed inside the impurity removal discharge pipe 3, dividing the interior of the impurity removal discharge pipe 3 into a pre-filtration chamber 13 and a post-filtration chamber 12. The post-filtration chamber 12 is connected to the upper end of the solution discharge pipe 7 and the backwash pipe 8. The pre-filtration chamber 13 is connected to the upper end of the impurity removal pipe 6. A fixed baffle 15 is installed at the upper end of the pre-filtration chamber 13. The fixed baffle 15 is fixed to the inner wall of the impurity removal discharge pipe 3, and the end of the fixed baffle 15 away from the inner wall of the impurity removal discharge pipe 3 is inclined downward to facilitate the passage of ammonium perchlorate raw material solution and metal impurities. An entry channel 16 is left between the fixed baffle 15 and the filter cotton layer 11, allowing the ammonium perchlorate raw material solution and metal impurities to enter the pre-filtration chamber 13. When impurities enter the pre-filtration chamber 13, the metal impurities are filtered out by the filter cotton layer 11 and remain in the pre-filtration chamber 13, while the ammonium perchlorate raw material solution enters the post-filtration chamber 12. The impurity removal pipe 6 and the solution discharge pipe 7 are respectively designed with a first solenoid valve 9 and a second solenoid valve 10. When the first solenoid valve 9 is opened, the metal impurities are discharged from the impurity removal pipe 6. When the second solenoid valve 10 is opened, the ammonium perchlorate raw material solution is discharged from the solution discharge pipe 7. The backwash pipe 8 is equipped with a third solenoid valve. When the third solenoid valve is opened, air can be blown into the post-filtration chamber 12 through the backwash pipe 8. The air backwashes the filter cotton layer 11, blowing the metal impurities remaining in the impurity removal discharge pipe 3 and on the surface of the filter cotton layer 11 to the impurity removal pipe 6 for discharge, thus achieving the purpose of backwashing and cleaning without the need for frequent manual cleaning.

[0029] refer to Figure 3 and Figure 4 As shown, a movable baffle 14 is further fixedly installed at the upper end of the filter cotton layer 11. The movable baffle 14 is arranged at an angle, and the end of the movable baffle 14 near the fixed baffle 15 is inclined downward. Since the filter cotton layer 11 has a certain degree of flexibility, when air is blown into the filtered chamber 12 through the backwash pipe 8, the gas will blow under the movable baffle 14 after passing through the filter cotton layer 11. The movable baffle 14 flips upward and fits against the lower surface of the fixed baffle 15, which can close the inlet channel 16 and prevent metal impurities from being discharged from the inlet channel 16 during air backwashing.
