[0031] In order to further explain the technical means and effects adopted by the utility model for realizing the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0032] Please refer to Figures 1-10The purpose of the present embodiment is to provide a water-soluble fertilizer raw material horizontal screw mixer with impurity removal function. It includes a shell 1, a feed inlet 11 fixedly arranged at the top of the shell 1, a screw mixer 12 rotatably installed in the shell 1, a screening part 2 inserted into the feed inlet 11 for screening impurities in the water-soluble fertilizer raw material, the screening part 2 including several sieve plates with gradually decreasing hole diameters, a blower 3 fixedly arranged on one side of the feed inlet 11, and the blower 3 for blowing away dust and impurities.

[0033] The screw mixer 12 includes screw blades, which are shaped like a screw and usually consist of two to three blades arranged in a spiral on the stirring shaft. The outer diameter of the screw blade is equal to the pitch, which helps to generate strong shear and convection during mixing. The rotation of the screw blade also generates convection in the shell 1. Specifically, the inner screw transports the material outward, and the outer screw gathers the material inward, which helps to fully turn and mix the raw material in the shell 1, ensuring that the raw material in every corner is evenly stirred. The high-speed rotation of the screw blade also generates centrifugal force, which helps to scatter and disperse the raw material along the cylinder wall, further improving the mixing effect.

[0034] The screening part 2 includes at least a first sieve plate 21 and a second sieve plate 22, both of which are fixedly provided with magnets 4 in a grid columnar design and evenly distributed below the sieve plates. The main function of the magnets 4 is to adsorb and remove metal impurities such as iron filings and nails that may exist in the water-soluble fertilizer raw material. If these metal impurities are not removed, they may cause equipment damage or affect product quality during production. Through the adsorption of the magnets 4, these metal impurities can be effectively separated from the raw material, ensuring the purity and safety of the raw material.

[0035] The grid columnar design of the magnets 4 increases their surface area, thereby improving the adsorption efficiency of metal impurities. This allows the magnets 4 to more fully contact the water-soluble fertilizer raw material, ensuring that more metal impurities are adsorbed, and the gaps between them help prevent the water-soluble fertilizer raw material from clogging during screening. The magnets 4 also have strong adaptability, which can adapt to different types and properties of water-soluble fertilizer raw materials, ensuring that metal impurities can be effectively removed under various conditions.

[0036] The first sieve plate 21 is fixedly provided with a fixed plate 211 on both sides, which provides stable support and fixing. The first sieve plate 21 is additionally provided with a sliding groove 212 on the other two sides, and a connecting groove 214 is also provided in the first sieve plate 21, which is in communication with the sliding groove 212 to form an inverted L-shaped groove. The connecting groove 214 is provided with a limiting hole 213 at one end.

[0037] The second screen plate 22 is fixedly provided on two opposite sides of the second screen plate 22, and a sliding plate 221 is fixedly connected to one side of the sliding plate 221. The sliding plate 221 is slidingly installed in a sliding groove 212, and a connecting plate 222 is slidingly installed in a connecting groove 214, so that the second screen plate 22 is slidingly installed on the first screen plate 21.

[0038] The connecting plate 222 is vertically slidingly provided with a limiting column 223 at one end, and the limiting column 223 is inserted into a limiting hole 213. The main function of the limiting column 223 is to serve as a fixing and limiting mechanism. When the connecting plate 222 slides into the connecting groove 214, the limiting column 223 cooperates with the limiting hole 213. The lower end of the limiting column 223 is designed to be inclined. During the process of slidingly inserting the connecting plate 222 into the connecting groove 214, the inclined part of the limiting column 223 will first contact the lower wall of the connecting groove 214. With the continuous sliding of the connecting plate 222, the limiting column 223 will be gradually lifted until it is concentric with the limiting hole 213. When the limiting column 223 is concentric with the limiting hole 213, it will slide downward along the vertical part of the limiting hole 213 and finally be inserted into the limiting hole 213. At this time, the close cooperation between the limiting column 223 and the limiting hole 213 firmly fixes the second screen plate 22 on the first screen plate 21.

[0039] Through the inclined design of the limiting column 223 and the cooperative design of the limiting hole 213, the second screen plate 22 can be easily and stably installed on the first screen plate 21. This design not only improves the stability and efficiency of the screening part 2, but also makes the disassembly and replacement of the second screen plate 22 more convenient and fast. At the same time, the inclined limiting column 223 and the limiting hole 213 also have good self-guiding and self-positioning functions, which further simplify the installation process and improve the accuracy of installation.

[0040] Grooves 111 are formed on both sides of the feed inlet 11, and the fixed plate 211 is inserted into the grooves 111, so that the first screen plate 21 is inserted into the feed inlet 11, and the screening part 2 is inserted into the feed inlet 11. The fixed plate 211 is threadedly installed with screws at both ends, and the grooves 111 are designed with screw holes matched with the screws. These screw holes allow the screws to pass through the fixed plate 211 and be screwed into the grooves 111, so that the first screen plate 21 is firmly fixed on the feed inlet 11. The first screen plate 21 is fixed or disassembled by using a screwdriver to tighten or loosen the screws.

[0041] The blower 3 is installed above the screening part 2, and such a layout ensures that the air flow blown by the blower 3 can directly act on the water-soluble fertilizer raw materials on the screening part 2, thereby achieving the effect of dust removal and impurity removal. The blowing end of the blower 3 is inserted and connected with an air outlet plate 31, and a plurality of air outlets are formed through the air outlet plate 31. For raw materials with larger particles and heavier specific gravity, an air outlet plate 31 with larger air outlets can be selected to increase the penetration and coverage of the air flow. For raw materials with smaller particles and lighter specific gravity, an air outlet plate 31 with smaller air outlets can be selected to reduce the impact of the air flow and prevent the raw materials from flying. The insertion and connection of the air outlet plate 31 gives it great flexibility. Users can easily replace the air outlet plate 31 with different sizes of air outlets according to actual needs, thereby removing dust and impurities to the greatest extent while avoiding unnecessary damage or pollution to the raw materials. Such an insertion and connection design not only facilitates the replacement and cleaning of the air outlet plate 31, but also ensures the close connection between the air outlet plate 31 and the blower 3, thereby avoiding air flow leakage.

[0042] A guide plate 5 is hingedly arranged on one side of the inner wall of the feeding port 11, and the guide plate 5 is located below the blower 3. The main function of the guide plate 5 is to guide the air flow generated by the blower 3 so that it can uniformly cover the surface of the water-soluble fertilizer raw materials on the screening part 2. Since the guide plate 5 is hingedly arranged, its angle can be adjusted according to actual needs. By adjusting the angle of the guide plate 5, the flow direction and intensity of the air flow can be changed, thereby adapting to different types and properties of water-soluble fertilizer raw materials, making it more efficient to remove dust from various raw materials, improving production efficiency and product quality, and also avoiding the formation of dead angles or vortexes inside the feeding port 11, thereby improving dust removal efficiency.

[0043] A plurality of streamline-shaped shunt bars 51 are fixedly arranged on the guide plate 5. The shunt bars 51 are mainly used to disperse and uniformly distribute the air flow generated by the blower 3, and the inclination angles of the shunt bars 51 are different. The shunt bars 51 are inclined by 5-85° along the direction of the air outlets. The streamline design can reduce the resistance of the air flow on the surface of the shunt bars 51, making the air flow pass more smoothly. At the same time, the different shapes and inclination angles of the shunt bars 51 can also disperse the air flow, avoiding the impact on the raw materials caused by the concentration of the air flow. The shunt bars 51 uniformly distribute the air flow generated by the blower 3 on the surface of the water-soluble fertilizer raw materials on the screening part 2, which not only improves the dust removal efficiency, but also ensures that the raw materials are uniformly affected by the air flow during the screening process, thereby improving the screening efficiency and quality.

[0044] Under the joint action of the guide plate 5 and the splitter strip 51, the airflow generated by the blower 3 can uniformly cover the surface of the water-soluble fertilizer raw materials on the screening part 2. This uniform airflow distribution not only improves the dust removal efficiency, but also ensures that the raw materials are subjected to uniform forces during screening, thereby improving the screening efficiency and quality. At the same time, due to the streamline design of the splitter strip 51 and the combination of different shapes and inclination angles, unnecessary impact and loss of airflow on the raw materials can also be avoided.

[0045] Through the cooperation of the blower 3 and the air outlet plate 31, the dust and particulate impurities on the screening part 2 are effectively removed. This not only improves the purity of the water-soluble fertilizer raw materials, but also reduces the difficulty and cost in subsequent processing. At the same time, the raw materials after dust removal are smoother during screening, and the screening efficiency is also significantly improved.

[0046] In specific use, the sliding plate 221 of the second sieve plate 22 is aligned with the sliding groove 212 of the first sieve plate 21, the connecting plate 222 is aligned with the connecting groove 214, and is slidably installed. During the sliding process of the connecting plate 222, the limiting column 223 will be gradually lifted until it is concentric with the limiting hole 213, and then inserted therein. According to the need, select the appropriate air outlet plate 31 and insert it at the blowing end of the blower 3. According to the need, adjust the angle of the guide plate 5, start the blower 3 and the spiral belt mixer 12, and slowly put the water-soluble fertilizer raw materials into the shell 1 through the feeding port 11. During the feeding process, the dust and impurities in the water-soluble fertilizer raw materials will be blown away by the blower 3, and then enter the screening part 2, and the granular impurities of different sizes are screened and left by the sieve plate. During this process, the metal impurities in the water-soluble fertilizer raw materials are adsorbed by the magnet 4, and the impurity-removed water-soluble fertilizer raw materials enter the inside of the shell 1 and are mixed by the spiral belt mixer 12.

[0047] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiments with equivalent changes and modifications are still within the scope of the present application.
