Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer technology, specifically to a compound fertilizer granulator with adjustable screening function. Background Technology

[0002] Compound fertilizer is a chemical fertilizer made of two or more nutrients, including major elements such as nitrogen, phosphorus, and potassium, as well as some trace elements. It has the advantages of balanced nutrition and long-lasting effect, and is widely used in agricultural planting, landscaping, and flower planting. In the production process of compound fertilizer, compound fertilizer granulators are indispensable forming equipment. In order to ensure the uniformity of compound fertilizer particles, it is necessary to use a compound fertilizer granulator with screening function to accurately screen compound fertilizer particles that meet the particle size range according to production requirements, remove particles that are too large or too small, make the product particles more uniform in size, and improve the quality and market competitiveness of the product.

[0003] However, existing compound fertilizer granulators with screening functions have simple structures and usually rely on a single screening component to screen the semi-finished compound fertilizer. They lack a structure for grading and screening the semi-finished compound fertilizer, resulting in low screening efficiency and accuracy. Therefore, we propose a compound fertilizer granulator with adjustable screening function. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a compound fertilizer granulator with adjustable screening function. It has a structure that uses a No. 1 screen and a No. 2 screen to classify and screen the compound fertilizer semi-finished product. It can effectively screen compound fertilizer semi-finished products with different particle sizes, thereby improving the uniformity of compound fertilizer particles. Moreover, both the No. 1 screen and the No. 2 screen have anti-clogging function, which can effectively improve screening efficiency and screening accuracy.

[0005] The technical solution adopted by this utility model to solve its technical problem is a compound fertilizer granulator with adjustable screening function, including a base, a granulation chamber, a screening channel, a first screening component and a second screening component. The screening channel is fixed at one end of the top of the base. The top of the screening channel is connected to the granulation chamber. A feeding hopper is installed on the top of the granulation chamber. The first screening component is provided at the upper end of one side of the screening channel. The first screening component includes a first hydraulic push rod, a first U-shaped connecting frame and a first screen. The output end of the first hydraulic push rod is connected to the first U-shaped connecting frame. The first screen is installed at one end of the first U-shaped connecting frame. A second screening assembly is provided at the lower end of one side of the screening channel. The second screening assembly includes a second hydraulic push rod, a second U-shaped connecting frame, and a second screen. The output end of the second hydraulic push rod is connected to the second U-shaped connecting frame, and a second screen is installed at one end of the second U-shaped connecting frame. A discharge channel is provided at the bottom of one side of the screening channel, and an inclined discharge plate is provided at the inner bottom of the discharge channel.

[0006] By adopting the above technical solution, this new compound fertilizer granulator has a structure that uses No. 1 screen and No. 2 screen to classify and screen the compound fertilizer semi-finished product. It can effectively screen compound fertilizer semi-finished products with different particle sizes, thereby improving the uniformity of compound fertilizer particles. Moreover, both No. 1 screen and No. 2 screen have anti-clogging function, which can effectively improve screening efficiency and screening accuracy.

[0007] Specifically, L-shaped support frames are fixed on both sides of the granulation chamber, and clamps are provided around the first hydraulic push rod and the second hydraulic push rod. Both ends of the clamps are connected to the L-shaped support frames by bolts.

[0008] By adopting the above technical solution, and through the cooperation of clamps and L-shaped support frames, personnel can securely install the No. 1 screening component and the No. 2 screening component on both sides of the screening channel.

[0009] Specifically, a storage cylinder is provided at the top of the base and at one end of the screening channel, and handles are installed on both sides of the storage cylinder.

[0010] Specifically, reserved openings are provided at the upper and lower ends of the outer side of the screening channel.

[0011] Specifically, a nameplate is mounted on one side of the base using screws.

[0012] The beneficial effects of this utility model are: (1) The compound fertilizer granulator with adjustable screening function described in this utility model allows the compound fertilizer semi-finished product particles to fall onto the surface of the No. 1 screen. The No. 1 screen can retain the compound fertilizer semi-finished product particles with larger particle size, while the semi-finished product particles smaller than the No. 1 screen aperture can pass through the No. 1 screen. The semi-finished product particles with a particle size larger than the No. 2 screen aperture cannot pass through the No. 2 screen and are retained by the No. 2 screen, while the semi-finished product particles smaller than the No. 2 screen aperture can pass through the No. 2 screen, thereby achieving the purpose of grading and screening the compound fertilizer semi-finished product particles.

[0013] (2) The compound fertilizer granulator with adjustable screening function described in this utility model has rhomboid holes on the No. 1 screen and the No. 2 screen. The four inclined sides of the rhomboid holes can form multi-directional flow surfaces, allowing the semi-finished particles to deflect at a larger angle. No matter which direction the semi-finished particles hit the screen holes, they can find a suitable passage path, avoiding the semi-finished products from getting stuck on the edge of the screen holes, thus achieving the purpose of preventing blockage.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] To improve screening efficiency and accuracy, No. 1 and No. 2 screens are used for grading and screening of compound fertilizer semi-finished products. Figure 1-4 As shown, the compound fertilizer granulator with adjustable screening function of this utility model includes a base 1, a granulation chamber 2, a screening channel 3, a first screening component 4 and a second screening component 5. The screening channel 3 is fixed at one end of the top of the base 1. The top of the screening channel 3 is connected to the granulation chamber 2. The top of the granulation chamber 2 is equipped with a feeding hopper 7. The first screening component 4 is provided at the upper end of one side of the screening channel 3. The first screening component 4 includes a first hydraulic push rod 401, a first U-shaped connecting frame 402 and a first screen 403. The output end of the first hydraulic push rod 401 is connected to the first U-shaped connecting frame 402. The first screen 403 is installed at one end of the first U-shaped connecting frame 402. A second screening component 5 is provided at the lower end of one side of the screening channel 3. The second screening component 5 includes a second hydraulic push rod 501, a second U-shaped connecting frame 502, and a second screen 503. The output end of the second hydraulic push rod 501 is connected to the second U-shaped connecting frame 502. The second screen 503 is installed at one end of the second U-shaped connecting frame 502. A discharge channel 11 is provided at the bottom of one side of the screening channel 3. An inclined discharge plate 13 is provided at the inner bottom of the discharge channel 11.

[0019] When in use, the compound fertilizer semi-finished particles fall onto the surface of the No. 1 screen 403. The No. 1 screen 403 can intercept the compound fertilizer semi-finished particles with larger particle sizes, while the semi-finished particles with smaller than the aperture of the No. 1 screen 403 can pass through the No. 1 screen 403. The semi-finished particles with larger than the aperture of the No. 2 screen 503 cannot pass through the No. 2 screen 503 and are intercepted by the No. 2 screen 503, while the semi-finished particles with smaller than the aperture of the No. 2 screen 503 can pass through the No. 2 screen 503, thereby achieving the purpose of grading and screening the compound fertilizer semi-finished particles. The apertures on screen 403 (No. 1) and screen 503 (No. 2) are designed to be rhomboid. The four slanted sides of the rhomboid aperture can form multiple flow guide surfaces, allowing semi-finished particles to deflect at a larger angle. No matter which direction the semi-finished particles hit the screen aperture, they can find a suitable passage path, avoiding the semi-finished products from getting stuck at the edge of the screen aperture, thus achieving the purpose of preventing blockage.

[0020] For example, such as Figure 1 As shown, L-shaped support frames 9 are fixed on both sides of the granulation chamber 2. Clamps 15 are provided on the periphery of the first hydraulic push rod 401 and the second hydraulic push rod 501. Both ends of the clamps 15 are connected to the L-shaped support frames 9 by bolts.

[0021] In use, by using the clamp 15 and the L-shaped support frame 9, personnel can secure the No. 1 screening component 4 and the No. 2 screening component 5 to both sides of the screening channel 3.

[0022] For example, such as Figure 1 As shown, a storage cylinder 6 is provided on the top of the base 1 and at one end of the screening channel 3, and handles 12 are installed on both sides of the storage cylinder 6.

[0023] When in use, the feed end of the storage cylinder 6 is located below the discharge end of the discharge channel 11, and the handle 12 facilitates the handling of the storage cylinder 6.

[0024] For example, such as Figure 2 , Figure 3 As shown, reserved openings 8 are provided at the upper and lower ends of the outer side of the screening channel 3.

[0025] When in use, the reserved openings 8 at the upper and lower ends of the outer side of the screening channel 3 facilitate the entry and exit of the No. 1 screen 403 and the No. 2 screen 503 into and out of the screening channel 3.

[0026] For example, such as Figure 1 As shown, a nameplate 10 is mounted on one side of the base 1 by screws.

[0027] In use, personnel can feed the raw materials required for compound fertilizer production into the granulation chamber 2 through the feeding hopper 7. After the raw materials are granulated in the granulation chamber 2, the semi-finished compound fertilizer can enter the screening channel 3. The semi-finished compound fertilizer falls onto the surface of the No. 1 screen 403. The aperture of the No. 1 screen 403 is designed to be smaller than the particle size of the semi-finished compound fertilizer. Therefore, the semi-finished compound fertilizer larger than the standard value is intercepted by the No. 1 screen 403, while the semi-finished product smaller than the aperture of the No. 1 screen 403 can pass through the No. 1 screen 403. Furthermore, the compound fertilizer semi-finished product continues to fall, landing on the surface of the second screen 503. The aperture of the second screen 503 is also standardized and smaller than that of the first screen 403. Therefore, among the semi-finished products that fall through the first screen 403, those with a particle size larger than that of the second screen 503 cannot pass through the second screen 503 and are retained by it, while those with a particle size smaller than that of the second screen 503 can pass through the second screen 503. Furthermore, the apertures on screen 403 (No. 1) and screen 503 (No. 2) are designed to be rhomboid. The four slanted sides of the rhomboid aperture can form multiple flow guide surfaces, allowing semi-finished particles to deflect at a larger angle. No matter which direction the semi-finished particles hit the screen aperture, they can find a suitable passage path, avoiding the semi-finished products from getting stuck at the edge of the screen aperture, thus achieving the purpose of preventing blockage. Furthermore, the compound fertilizer semi-finished product can be moved into the storage cylinder 6 through the discharge channel 11. After the granulator stops, the personnel can remove the storage cylinder 6 by gripping the handle 12, and then clean the storage cylinder 6.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
