Description

Technical Field

[0001] This utility model belongs to the technical field of water-soluble fertilizer production equipment, and in particular, it is a vibrating screen device for water-soluble fertilizer production. Background Technology

[0002] Water-soluble fertilizers refer to compound fertilizers containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid, etc., which can be completely dissolved in water. Solid water-soluble fertilizers are fast-acting fertilizers with good water solubility and no residue. They can be completely dissolved in water and directly absorbed and utilized by the roots and leaves of crops. Existing vibrating screen devices are prone to material accumulation and incomplete screening when processing large quantities of materials, which affects production efficiency.

[0003] A search revealed Chinese patent document (authorization announcement number CN221734077U), which discloses a vibrating screen device for water-soluble fertilizer production. This invention relates to the technical field of vibrating screen devices for water-soluble fertilizer production, and includes a screening box. The screening box has an internal screening mechanism for screening water-soluble fertilizer. The screening mechanism includes a screen assembly disposed inside the screening box, comprising a top plate fixedly installed inside the top plate of the screening box. Four upper mounting blocks are fixedly installed at the bottom of the top plate, and first spring plates are fixedly installed on the inner side of each upper mounting block. The device has a screen assembly where large-aperture and small-aperture screens are stacked together via a first spring plate and a second spring plate, thus separating the screening process. The large-aperture and small-aperture screens work independently without interfering with each other, which improves screening efficiency and accuracy. Furthermore, if either the large-aperture or small-aperture screen becomes worn or damaged and needs replacement or repair, it can be easily replaced or repaired, reducing maintenance costs. This device can meet basic usage requirements. However, when processing large quantities of material, the vibrating screen device is prone to material accumulation and incomplete screening, affecting production efficiency. Utility Model Content

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 The vibrating screen device for water-soluble fertilizer production shown includes a support frame 1 for supporting water-soluble fertilizer raw materials, and an anti-blocking box 2 is provided on the top of the support frame 1.

[0027] The vertical inner wall of the anti-clogging box 2 is equipped with a crushing disc 305 for crushing water-soluble fertilizer raw materials. A guide post 306 is rotatably connected inside the crushing disc 305. A sliding spring post 3 is installed on the top of the guide post 306. A compression spring 301 is connected inside the spring post 3. One end of the compression spring 301 is connected to a circular plate 302, which is slidably positioned inside the spring post 3. A connecting post 303 is connected to the outer periphery of the circular plate 302. Two U-shaped grooves for sliding of the connecting post 303 are symmetrically arranged on the outer periphery of the spring post 3. Both ends of the connecting post 303 are rotatably mounted... A crushing wheel 304 is provided for crushing large-particle water-soluble fertilizer raw materials. A limit post 204 is welded to the end of the circular plate 302 away from the compression spring 301. When too much water-soluble fertilizer raw material enters, the spring post 3 drives the connecting post 303 and the crushing wheel 304 to rotate. The crushing wheel 304 squeezes and crushes the water-soluble fertilizer raw material on the crushing disc 305 to prevent the water-soluble fertilizer raw material from clogging. The compression spring 301 pulls the circular plate 302 and the crushing wheel 304 to continuously contact the water-soluble fertilizer raw material on the crushing disc 305. The contact pressure between the crushing wheel 304 and the water-soluble fertilizer raw material can be adapted to prevent damage to the equipment.

[0028] The top of the anti-clogging box 2 is connected to a feed pipe 202 for the water-soluble fertilizer raw materials to enter. A servo motor 201 is installed on the top of the anti-clogging box 2. The output shaft of the servo motor 201 is connected to a rotating shaft 203 through a coupling. The end of the rotating shaft 203 is connected to the top of the limiting post 204. When the servo motor 201 is turned on, the servo motor 201 drives the rotating shaft 203, the limiting post 204 and the spring post 3 to rotate.

[0029] The bottom of the anti-clogging box 2 is connected to the dispersion box 104. Inside the dispersion box 104, a dispersion wheel 103 for dispersing water-soluble fertilizer raw materials is rotatably installed. The bottom of the dispersion box 104 is provided with a discharge port 105 for discharging the dispersed raw materials. Inside the support frame 1, a power unit 101 for providing power is installed. The power unit 101 is usually an electric motor, hydraulic motor or other power equipment. Through energy conversion such as electrical energy and hydraulic energy, it outputs rotational power (torque and speed). This is the source of the entire transmission chain. The output shaft of the power unit 101 is rigidly connected to the connecting part 102 (such as a coupling, gear set, belt / chain transmission mechanism, etc.) to transmit power to the dispersion wheel 103. The movable part of the power unit 101 is connected to the connecting part 102. The movable part of the connecting part 102 is connected to the dispersing wheel 103. The water-soluble fertilizer raw material is added to the crushing disc 305 in the anti-clogging box 2 through the feed pipe 202. The water-soluble fertilizer raw material enters the dispersing box 104 through the crushing disc 305. The power unit 101 is turned on. The power unit 101 drives the dispersing wheel 103 to rotate through the connecting part 102. The dispersing wheel 103 disperses the water-soluble fertilizer raw material and then enters the vibrating box 106 through the discharge port 105.

[0030] The support frame 1 is equipped with four vibration springs 109. The ends of the four vibration springs 109 are equipped with a vibrating box 106 for screening water-soluble fertilizer. The vibrating box 106 is equipped with a screen 107 for screening. The bottom of the vibrating box 106 is connected to a fine discharge pipe 108 for discharging the screened water-soluble fertilizer raw materials. A coarse discharge port 110 is provided on the side of the vibrating box 106. A vibrator is installed at the bottom of the vibrating box 106. The vibrator generates high-frequency vibration through electromagnetic or mechanical principles and transmits the vibration to the vibrating box 106. The material is kept in a flowing state under the action of vibration force and gravity, avoiding accumulation and blockage of the inlet. At the same time, it helps to disperse agglomerated materials and ensure smooth feeding. The vibrator drives the vibrating box 106 to vibrate. The screen 107 screens the water-soluble fertilizer raw materials. The screened fine raw materials are discharged through the fine discharge pipe 108, and the coarse raw materials are discharged through the coarse discharge port 110.

[0031] Working principle

[0032] In operation, the vibrating screen device for water-soluble fertilizer production first feeds the water-soluble fertilizer raw material into the crushing disc 305 inside the anti-clogging box 2 through the feed pipe 202. The raw material then enters the dispersion box 104 through the crushing disc 305. The power unit 101 is then turned on, and it drives the dispersing wheel 103 to rotate via the connecting part 102. The dispersing wheel 103 disperses the incoming water-soluble fertilizer raw material, which then enters the vibrating box 106 through the discharge port 105. The vibrator drives the vibrating box 106 to vibrate, and the screen 107 screens the water-soluble fertilizer raw material. The fine raw material is discharged through the fine discharge pipe 108, while the coarse raw material... The raw material is discharged through the coarse outlet 110. When too much water-soluble fertilizer raw material enters, the servo motor 201 is turned on. The servo motor 201 drives the rotating shaft 203, the limit post 204 and the spring post 3 to rotate. The spring post 3 drives the connecting post 303 and the crushing wheel 304 to rotate. The crushing wheel 304 squeezes and crushes the water-soluble fertilizer raw material on the crushing disc 305 to prevent the water-soluble fertilizer raw material from clogging. The compression spring 301 pulls the circular plate 302 and the crushing wheel 304 to continuously contact the water-soluble fertilizer raw material on the crushing disc 305. The contact pressure between the crushing wheel 304 and the water-soluble fertilizer raw material can be adapted to prevent damage to the equipment.
