Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening equipment technology, specifically to a screening device for potassium chloride production. Background Technology
[0002] Potassium chloride fertilizer is a common potassium-containing fertilizer that plays a crucial role in agriculture. Visually, it typically appears as white or light yellow crystalline granules with a relatively uniform texture. Granule size varies depending on the production process and intended use. In the production of potassium chloride fertilizer, the screening process is essential to ensure product quality. Overly large potassium chloride granules result in slow dissolution and uneven fertilization; therefore, screening is necessary.
[0003] Traditional screening equipment is mostly simple in structure, generally only equipped with a flat screen for material screening. However, in actual production applications, because potassium chloride fertilizer is granular, it is very easy for it to accumulate on the flat screen during the screening process, reducing the production efficiency of potassium chloride.
[0004] To address the aforementioned issues, we propose a screening device for potassium chloride production. Utility Model Content
[0005] The purpose of this invention is to provide a screening device for potassium chloride production to address the aforementioned shortcomings in the technology.

[0007] Preferably, a motor mounting cover is fixedly provided on one side of the outer wall of the screening cylinder, and the motor is installed inside the motor mounting cover.
[0008] Preferably, a discharge pipe is fixedly provided at the bottom center of the arc-shaped fixing cover through an opening.
[0009] Preferably, a discharge port is provided on the outer wall of one side of the bottom of the screening cylinder, and a door panel is movably connected to the top inner wall of the discharge port via a hinge. A handle is fixedly provided on one side of the outer wall of the door panel.
[0010] Preferably, a vertically upward feeding pipe is installed at the top center of the screening cylinder through an opening, and a feeding hopper is connected to the top of the feeding pipe.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] By setting an arc-shaped screen at the bottom of the screening cylinder and using an arc-shaped fixing cover, the electric motor drives the rotating rod and the turning plate to rotate. The outer wall of the turning plate is in contact with the inner wall of the arc-shaped screen, and the potassium chloride fertilizer can be continuously turned over during the rotation, avoiding the problem of insufficient screening caused by fertilizer accumulation and greatly improving the screening efficiency.

[0026] Example 2
[0027] Based on Embodiment 1, a motor 5 is installed at the center of the outer wall of one side of the screening cylinder 1. The motor 5 is first installed inside the motor fixing cover 4 fixed to the outer wall of one side of the screening cylinder 1. The output shaft of the motor 5 passes through the outer wall of the screening cylinder 1 and is fixedly connected to the rotating rod 6 through a coupling. The outer wall of the rotating rod 6 is fixed with the turning plates 7 at equal intervals through the bracket. The outer wall of the turning plates 7 is in contact with the inner wall of the arc-shaped screen 2. After the motor 5 is started, it drives the rotating rod 6 to rotate, thereby causing the turning plates 7 to turn over the potassium chloride fertilizer in the arc-shaped screen 2, thereby improving the screening efficiency.
[0028] Example 3
[0029] Based on Embodiment 1, a discharge port 9 is opened on the outer wall of one side of the bottom of the screening cylinder 1. The top inner wall of the discharge port 9 is movably connected to the door panel 10 by a hinge. A handle is fixedly installed on the outer wall of one side of the door panel 10. Large particles of potassium chloride fertilizer that have not passed through the arc-shaped screen 2 can be discharged from the discharge port 9 by opening the door panel 10. An opening is opened at the center of the top of the screening cylinder 1 and a vertically upward feeding pipe 11 is installed. The top of the feeding pipe 11 is connected to the feeding hopper 12. Potassium chloride fertilizer enters the screening cylinder 1 from the feeding hopper 12 through the feeding pipe 11.
[0030] Example 4
[0031] Based on Embodiment 1, fixing columns 13 are fixedly installed at the bottom of the outer walls on both sides of the screening cylinder 1. Vertical support legs 14 are fixedly installed on the outer walls of the fixing columns 13 to support the entire device. The motor 5 is connected to the power switch through wires, and the power switch is connected to the power cord. The start and stop of the motor 5 are controlled by operating the power switch.
[0032] Working principle of this utility model:
[0033] Refer to the instruction manual appendix Figure 1-4 When using this utility model, the supporting legs 14 are used to place the utility model in a designated position, and the power cord is connected. The granular potassium chloride fertilizer to be screened is poured into the feeding hopper 12. The fertilizer enters the screening cylinder 1 through the feeding pipe 11. Then, the power switch is turned on, the motor 5 starts, and its output shaft drives the rotating rod 6 to rotate. The turning plate 7 on the rotating rod 6 rotates accordingly and turns the potassium chloride fertilizer in the arc screen 2. Under the action of the turning plate 7, the fine granular potassium chloride fertilizer that meets the particle size requirements falls through the arc screen 2 into the arc fixed cover 3 and is discharged from the discharge pipe 8 at the bottom of the arc fixed cover 3. The large granular potassium chloride fertilizer that does not pass through the arc screen 2 remains in the screening cylinder 1. After the screening is completed, the power switch is turned off, the motor 5 stops rotating, and the door panel 10 is opened by pulling the handle to discharge the remaining large granular potassium chloride fertilizer in the screening cylinder 1 from the discharge port 9.
