Description

Technical Field

[0001] This utility model relates to the field of potassium sulfate production technology, and in particular to a screening machine for granular potassium sulfate production. Background Technology

[0002] In the production process of granular potassium sulfate, screening is a crucial step, as its effectiveness directly affects product quality and production efficiency. As a chlorine-free, high-quality, and efficient potassium fertilizer, potassium sulfate is an indispensable fertilizer in the cultivation of chlorine-sensitive crops such as tobacco, grapes, sugar beets, tea trees, potatoes, flax, and various fruit trees. Therefore, before potassium sulfate is prepared and bagged, it must be screened by a screening machine to prevent clumping.

[0003] At present, the screen plates in the screening machines used for granular potassium sulfate production can screen a fixed size. Once it is necessary to adjust the screening specifications of potassium sulfate granules, it is often only possible to replace the entire screen plate. This is not only cumbersome and time-consuming, but also causes production interruption, which seriously affects production efficiency. Moreover, frequent replacement of screen plates will also significantly increase production costs. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: the size that the sieve plate in the screening machine for granular potassium sulfate production can screen is constant. Once it is necessary to adjust the screening specifications of potassium sulfate particles, it is often only possible to replace the entire sieve plate. This is not only cumbersome to operate and consumes a lot of time and manpower, but also causes production interruption, which seriously affects production efficiency. Moreover, frequent replacement of sieve plates will also greatly increase production costs. Therefore, a screening machine for granular potassium sulfate production is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A screening machine for producing granular potassium sulfate includes a machine body with a circular screening trough on its surface. The top and bottom of the machine body have an inlet and an outlet connected to the screening trough, respectively. A screen plate is rotatably mounted inside the screening trough.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0016] Reference Figure 1 and Figure 6A screening machine for granular potassium sulfate production includes a machine body 1, a circular screening trough 2 on the surface of the machine body 1, an inlet and an outlet connected to the screening trough 2 at the top and bottom of the machine body 1, respectively, a screen plate 3 rotatably mounted inside the screening trough 2, and a rotating port connected to the screening trough 2 on the back of the machine body 1. Figures 3-5 As shown, a rotating rod 4 is rotatably installed inside the rotating port, with one end fixedly connected to the screen plate 3. Multiple strip-shaped screen openings 5 ​​are equidistantly opened on the surface of the screen plate 3. An electric telescopic rod 6 is fixedly installed on the side wall of the machine body 1. The drive shaft of the electric telescopic rod 6 is fixedly installed with a machine door 7. The four sides of the screen plate 3 slide in contact with the walls of the screening tank 2 and the surface of the machine door 7.

[0017] Reference Figure 8 The rotating rod 4 is controlled to reciprocate through the drive assembly. The screen plate 3 has an installation groove 8 on its surface near the machine door 7. The screen opening 5 has a through opening 9 on one side wall that is connected to the installation groove 8. A movable plate 10 is slidably inserted into the through opening 9. A first threaded rod 11 is horizontally rotatably installed in the installation groove 8. A slider 12 is fixedly installed at one end of the movable plate 10. Multiple sliders 12 are threadedly sleeved on the first threaded rod 11 at equal intervals.

[0018] Start the drive assembly to control the rotating rod 4 to rotate back and forth, causing the screen plate 3 to rotate in the screening tank 2. At this time, granular potassium sulfate is put in through the feed port. Particles that meet the specifications are discharged through the screen opening 5 and the discharge port. A receiving container (not shown) can be preset below the discharge port to collect qualified particles after screening. However, larger particles that do not meet the specifications cannot pass through the screen opening 5 and will remain on the upper surface of the screen plate 3.

[0019] When it is necessary to change the screening size, simply rotate the first threaded rod 11 in the mounting groove 8 to drive the multiple threaded sliders 12 to move, so that the movable plate 10 connected to the slider 12 slides in the opening 9. By changing the volume of the movable plate 10 in the screen opening 5, the opening and closing width of the screen opening 5 can be adjusted. When the volume of the movable plate 10 in the screen opening 5 increases, the width of the screen opening 5 will decrease, and when the volume of the movable plate 10 in the screen opening 5 decreases, the width of the screen opening 5 will increase.

[0020] After shutting down the equipment, start the electric telescopic rod 6 to control the machine door 7 away from the machine body 1, clean the remaining particles on the screen plate 3, and after cleaning, use the electric telescopic rod 6 to control the machine door 7 to move closer to the machine body 1 and block it.

[0021] Reference Figure 2 The drive assembly includes a telescopic cylinder 13 and a second threaded rod 14 fixedly installed at the end of the drive shaft of the telescopic cylinder 13. One end of the rotating rod 4 is provided with a threaded groove 15 that matches the thread on the surface of the second threaded rod 14. One end of the second threaded rod 14 is threadedly installed in the threaded groove 15. An L-shaped plate is fixedly installed on the back of the machine body 1, and the telescopic cylinder 13 is fixedly installed on the surface of the L-shaped plate.

[0022] When the telescopic cylinder 13 is activated, its drive shaft extends and retracts, causing the second threaded rod 14 to move synchronously. Through the threaded engagement between the second threaded rod 14 and the threaded groove 15 at the end of the rotating rod 4, the linear motion of the telescopic cylinder 13 is converted into the reciprocating rotation of the rotating rod 4, which in turn drives the screen plate 3 to reciprocate within the screening trough 2, thereby achieving the screening operation.

[0023] Reference Figure 2 The machine body 1 has a mounting plate on its top, and a drive motor 16 is fixedly mounted on the surface of the mounting plate. The output shaft of the drive motor 16 is fixedly connected to a water pipe 17 corresponding to the feed inlet. A support plate is fixedly mounted on the upper surface of the machine body 1, and a mounting sleeve 29 is fixedly mounted on the top of the support plate. The mounting sleeve 29 is rotatably sleeved on the output shaft of the drive motor 16. Multiple water distribution pipes 18 are fixedly mounted at equal intervals on the surface of the water pipe 17. A water tank 19 is fixedly mounted on one side of the machine body 1. A water supply assembly for supplying water from the water tank 19 to the water pipe 17 is provided on the back of the machine body 1. The water supply assembly includes a mounting rod 20 and a plug rod 21 fixedly mounted on the back of the machine body 1. One end of the cylinder 0 has a slot, and the insertion rod 21 is slidably inserted into the slot. The mounting rod 20 is fixedly connected to the water pipe 17 through the water outlet hose 22, and the mounting rod 20 is fixedly connected to the water tank 19 through the water inlet pipe 23. Both the water inlet pipe 23 and the water outlet hose 22 are equipped with one-way valves. The one-way valve in the water inlet pipe 23 is directed from the water tank 19 to the slot, and the one-way valve in the water outlet hose 22 is directed from the slot to the water pipe 17. A sliding plate 24 is fixedly sleeved on the drive shaft of the telescopic cylinder 13. The surface of the sliding plate 24 has a through-hole 25 for the end of the insertion rod 21 to pass through. The sliding plate 24 is locked to the insertion rod 21 by a threaded component. Figure 7 As shown, the threaded component includes a locking bolt 26, a threaded hole 27 vertically opened on the top of the slide plate 24, and a locking groove 28 vertically opened on the surface of the insert rod 21. The locking bolt 26 is threadedly installed in the threaded hole 27, and the bottom end of the locking bolt 26 is inserted into the locking groove 28. The mounting sleeve 29 can provide stable support for the output shaft of the drive motor 16, and prevent the output shaft from shaking or deviating due to uneven force when the drive motor 16 drives the water pipe 17 and the water distribution pipe 18 to rotate, so as to ensure that the water pipe 17 and the water distribution pipe 18 rotate smoothly and ensure that the water flow is evenly sprayed during water supply or cleaning. On the other hand, it can reduce the operating load of the drive motor 16, reduce component wear, extend the service life of the drive motor 16, and improve the overall structural stability.

[0024] When cleaning the screening trough 2 and the screen plate 3, insert the end of the insert rod 21 through the through hole 25 of the slide plate 24, tighten the locking bolt 26, and insert the bottom end of the rod into the locking groove 28 to lock the slide plate 24 and the insert rod 21.

[0025] Then, start the drive motor 16 and control the water pipe 17 to rotate until it is horizontal above the feed inlet. At this time, start the telescopic cylinder 13, and drive the slide plate 24 to move back and forth, thereby driving the insertion rod 21 to slide in the slot. When the insertion rod 21 slides outward, the slot is under negative pressure, and water in the water tank 19 enters the slot through the one-way valve of the water inlet pipe 23. When the insertion rod 21 slides inward, the slot pressure increases, and water flows into the water pipe 17 through the one-way valve of the water outlet hose 22, and then flows out through the water distribution pipe 18. The water flowing out will enter the screening tank 2 from the feed inlet and will contact the reciprocating rotating screen plate 3 to achieve uniform water spraying and cleaning, which facilitates the cleaning of the inside of the machine body 1.

[0026] When screening particles without cleaning, first start the drive motor 16 to control the water pipe 17 to rotate vertically above the feed inlet so that the water pipe 17 does not block the input of raw materials into the feed inlet. Then rotate the locking bolt 26 so that its bottom end moves out of the locking groove 28, thereby releasing the lock between the slide plate 24 and the insertion rod 21. At this time, when the telescopic cylinder 13 is working, it only drives the rotating rod 4 to drive the screen plate 3 to screen, and the water supply component does not operate.

[0027] In this invention, simply rotating the first threaded rod 11 can drive multiple sliders 12 to move synchronously, thereby causing the moving plate 10 to slide within the opening 9, changing the actual opening and closing width of the sieve opening 5. This adjustment process does not require disassembly or replacement of the sieve plate 3, making the operation convenient and quick. It can easily adapt to the screening requirements of potassium sulfate particles of different sizes, greatly improving the equipment's adaptability to diverse production tasks, while avoiding the waste of manpower and time costs caused by frequent replacement of the sieve plate 3, and ensuring production continuity.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
