Description

Technical Field

[0001] This utility model relates to the field of particle size screening technology, and in particular to a particle size screening device for processing potassium persulfate compound powder. Background Technology

[0002] Potassium persulfate compound is widely used for wastewater disinfection and the purification of ponds or aquaculture water. However, potassium persulfate compound with different particle sizes has different applications and effects. Granular potassium persulfate compound has a stable structure and slowly releases disinfectant components after entering the water; powdered potassium persulfate compound dissolves rapidly after entering the water and diffuses downwards from the water surface to achieve a whole-pond disinfection effect. Therefore, during processing and production, it is necessary to screen the particle size of potassium persulfate compound to select the application scenario based on the particle size, or to facilitate subsequent processing.

[0003] In current particle size screening of potassium persulfate compound, the compound is mainly passed through an inclined screening plate. However, the compound passes through the screening plate too quickly and too much material can cause accumulation, resulting in small particles of potassium persulfate compound being carried through, leading to incomplete screening and requiring multiple screening processes. Utility Model Content

[0004] The purpose of this invention is to provide a particle size sieving device for processing potassium persulfate compound powder, so as to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a particle size screening device for processing potassium persulfate compound powder, including a screening box and a guide base. At least two partition plates are fixedly connected inside the screening box, and at least three screening plates are fixedly connected inside the screening box. The screening plates are provided with through screening holes in the middle. The screening plates are inclined to guide the falling potassium persulfate compound particles. The sieve plates are fixedly connected to both sides of the partition plate, and there is a height difference between two adjacent sieve plates, which is used to screen potassium persulfate compound particles of different particle sizes. The upper end of the partition plate is provided with a snap-fit ​​groove, and the middle of the snap-fit ​​groove is slidably connected to the baffle plate. The baffle plate extends out of the snap-fit ​​groove to block the rolling potassium persulfate compound particles. Both sides of the screening box are fixedly connected to fixed protrusions, which are located in the middle of the guide base. The guide base is provided with a first electric push rod in the middle, which is used to drive the screening box to move back and forth.

[0006] Preferably, the screening box is provided with a feed inlet on the side, and there is a height difference between the feed inlet outlet and the screening plate for preliminary screening of potassium persulfate compound particles. The diameter of the screening holes on the screening plate near the feed inlet is smaller than the diameter of the screening holes on the screening plate away from the feed inlet.

[0007] Preferably, the upper ends of the partition plate and the baffle plate are inclined surfaces. When the baffle plate is retracted into the snap-fit ​​groove, the upper surfaces of the partition plate, the baffle plate and the sieve plate are smoothly connected to ensure that the potassium persulfate compound particles roll smoothly.

[0008] Preferably, an auxiliary plate is fixedly connected to the upper end of the baffle plate. The auxiliary plate has a U-shaped structure, and the side end of the auxiliary plate abuts against the inner side wall of the screening box. A second electric push rod is fixedly connected to the upper end of both auxiliary plates to control the baffle plate to extend or retract into the locking groove.

[0009] Preferably, the guide base has a connecting groove in the middle, the lower end of the screening box is fixedly connected to a drive plate, and the power output end of the first electric push rod is fixedly connected to the drive plate.

[0010] Preferably, both sides of the guide base are fixedly connected with L-shaped side plates, the top of which abuts against the side wall of the screening box to limit the sliding of the screening box.

[0011] Preferably, a limiting strip is fixedly connected to the side of the side plate facing the fixed protrusion. The limiting strip has an arc-shaped structure. The side of the fixed protrusion facing the side plate has an arc-shaped surface, and a ball bearing is embedded on the arc-shaped surface. The top of the limiting strip is directly opposite the ball bearing. A triangular space is formed between the limiting strip and the side plate. The ball bearing is embedded on the side of the fixed protrusion facing the guide base.

[0012] Preferably, at least three feed boxes are connected to the side of the screening box by snap-fit, and a feed box is provided below each screening plate to receive potassium persulfate compound particles of different sizes.

[0013] The beneficial effects of this utility model are as follows: the screening box is equipped with at least two partition plates and at least three inclined screening plates with screening holes. There is a height difference between adjacent screening plates. Under the action of gravity, the potassium persulfate compound particles can pass through the screening plates with screening holes of different diameters in sequence to achieve multi-stage screening. It can screen out a variety of products with different particle sizes at one time, which greatly improves the screening efficiency and meets the diverse requirements of different production needs for particle size.

[0014] When potassium persulfate compound particles fall onto the screening plate below, due to inertia, the particles of different diameters fall at different distances, thus assisting in the screening of potassium persulfate compound particles and increasing the screening effect.

[0015] The baffle plate can block the rolling potassium persulfate compound particles, causing them to accumulate at each screening plate, and the screening box is moved back and forth by the first electric push rod, thereby increasing the screening efficiency. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] See Figures 1-4 The present invention provides a particle size sieving device for processing potassium persulfate compound powder, comprising a sieving box 2 and a guide base 1, characterized in that: at least two partition plates 14 are fixedly connected inside the sieving box 2, and the fixed connection method can also be welding, riveting, screwing or gluing, etc. The screening box 2 has at least three screening plates 16 fixedly connected inside. Each screening plate 16 has a through screening hole in the middle. The screening plates 16 are inclined to guide the falling potassium persulfate compound particles. Under the action of gravity, the potassium persulfate compound particles can pass through the screening plates with screening holes of different diameters in sequence, realizing multi-stage screening. It can screen out multiple products with different particle sizes at one time, which greatly improves the screening efficiency. Screening plates 16 are fixedly connected to both sides of the partition plate 14, with a height difference between adjacent screening plates 16, used for screening potassium persulfate compound particles of different sizes. A feed inlet 3 is provided on the side of the screening box 2, with a height difference between the outlet of the feed inlet 3 and the screening plates 16, used for preliminary screening of the potassium persulfate compound particles. The diameter of the screening holes on the screening plates 16 closer to the feed inlet 3 is smaller than the diameter of the screening holes on the screening plates 16 farther from the feed inlet 3. When the potassium persulfate compound particles fall onto the lower screening plates 16, due to inertia, particles of different diameters fall at different distances, thus providing auxiliary screening and increasing the screening effect.

[0023] A locking groove 15 is provided in the middle of the upper end of the partition plate 14. The locking groove 15 is slidably connected to the baffle plate 10. The baffle plate 10 extends out of the locking groove 15 to block the rolling potassium persulfate compound particles. An auxiliary plate 11 is fixedly connected to the upper end of the baffle plate 10. The auxiliary plate 11 has a U-shaped structure, and its side end abuts against the inner wall of the screening box 2. A second electric push rod 13 is fixedly connected to the upper end of both auxiliary plates 11 to control the baffle plate 10 to extend or retract into the locking groove 15. The baffle plate 10 can block the rolling potassium persulfate compound particles. When the screening box 2 is driven to move back and forth, the material on the screening plate 16 is shaken, thereby increasing the screening effect. When the second electric push rod 13 drives the auxiliary plate to move, the auxiliary plate drives the baffle plate 10 to retract into the locking groove 15. At this time, the potassium persulfate compound particles have no obstruction and roll onto the next screening plate 16.

[0024] The upper ends of the separator plate 14 and the baffle plate 10 are both inclined surfaces. When the baffle plate 10 is retracted into the snap-fit ​​groove 15, the upper surfaces of the separator plate 14, the baffle plate 10 and the sieve plate 16 are smoothly connected to ensure that the potassium persulfate compound particles roll smoothly.

[0025] Both sides of the screening box 2 are fixedly connected to fixed protrusions 8, which are located in the middle of the guide base 1. A first electric push rod 6 is located in the middle of the guide base 1, used to drive the screening box 2 to reciprocate. A connecting groove 4 is located in the middle of the guide base 1. A drive plate 5 is fixedly connected to the lower end of the screening box 2, and the power output end of the first electric push rod 6 is fixedly connected to the drive plate 5. The first electric push rod drives the drive plate and the screening box 2 to reciprocate, causing the material on the screening plate 16 to shake, thereby increasing the screening effect. A control chip is located on the outer wall of the screening box 2, used to control the two second electric push rods 13 to work sequentially and to control the first electric push rod 6 to drive the screening box 2 to reciprocate.

[0026] Both sides of the guide base 1 are fixedly connected with L-shaped side plates 12. The top of the side plates 12 abuts against the side wall of the screening box 2 to limit the sliding of the screening box 2. This allows the screening box 2 to move along the side plates 12, thus guiding the movement of the screening box 2.

[0027] A limiting strip 7 is fixedly connected to the side of the side plate 12 facing the fixed protrusion 8. The limiting strip 7 has an arc-shaped structure, and the side of the fixed protrusion 8 facing the side plate 12 is also arc-shaped, with ball bearings embedded on this arc-shaped surface. The top of the limiting strip 7 is directly opposite the ball bearings, forming a triangular space between the limiting strip 7 and the side plate 12, which increases the stability of the screening box 2. The fixed protrusion 8 also has ball bearings embedded on its side facing the guide base 1. The ball bearings reduce the friction when the screening box 2 moves. The limiting strip 7 and the side plate 12 work together to limit the movement of the screening box 2, preventing it from shaking during movement and ensuring its stability.

[0028] At least three feed boxes 9 are connected to the side of the screening box 2 via snap-fit ​​connections. Each screening plate 16 has a corresponding feed box 9 below it, used to receive potassium persulfate compound particles of different sizes. This allows products of different particle sizes to be collected separately into their respective feed boxes, facilitating subsequent packaging, storage, and use, and preventing the mixing of products of different particle sizes.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
