Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer production, specifically to a mixing tank for pretreatment of microbial compound fertilizer. Background Technology

[0002] Compound microbial fertilizers are live microbial products composed of specific microorganisms and nutrients, which can provide, maintain or improve plant nutrition, increase agricultural product yield or improve agricultural product quality. Microbial compound fertilizers are new types of fertilizers that add trace elements to the original chemical fertilizers, which can meet the needs of many crops.

[0003] The process flow of a compound fertilizer production line can generally be divided into: raw material preparation, raw material mixing, raw material granulation, granule drying, granule cooling, granule grading, finished product coating, and final finished product packaging. Among these, raw material mixing is a crucial step in the compound fertilizer preparation process. Uneven mixing of raw materials will result in uneven distribution of nutrients, thus affecting the subsequent fertilization effect. However, solid powder or small granular raw materials for compound fertilizers can clump together (due to moisture or slightly sticky surfaces). Mixing clumps with liquid raw materials requires a significant amount of time, increasing mixing time and easily leading to uneven mixing. Furthermore, after long-term use, some raw materials tend to adhere to the inner wall of the existing mixing equipment, making cleaning difficult. Utility Model Content

[0004] To address the aforementioned problems, specifically the issues raised in the background section, this utility model proposes a mixing tank for the pretreatment of microbial compound fertilizer. The tank comprises a tank body, a feed box, and a discharge pipe. The tank body has supporting legs at its bottom, and the bottom of the tank body is a frustum-shaped inverted cone. The feed box is fixed to the upper eccentric portion of the tank body via a pair of supporting plates. The other eccentric portion of the feed box is fixedly connected to the feed pipe. The lower eccentric portion of the feed box is connected to the upper side of the tank body via the discharge pipe. The tank body is equipped with a mixing structure, and the feed box contains a dispersing structure.

[0005] The stirring structure includes a motor, a shaft, a pair of pulleys, a belt, and a set of stirring blades;

[0006] The motor is installed at the bottom of the tank. The output end of the motor passes through the tank and is fixedly connected to the shaft. The upper end of the shaft is connected to and passes through the tank with a bearing. A set of evenly arranged stirring blades is fixedly connected to the outside of the shaft. A pulley is fixedly connected to the upper end of the shaft. A pair of pulleys are connected by a belt. The central shaft bearing of the other pulley is connected to the upper side of the tank. The other pulley is concentric with the feed box.

[0007] A further feature of this invention is that the dispersing structure includes a round rod, a circular filter plate, a set of dispersing rods, and a pair of brush plates.

[0008] The circular filter plate is placed in the middle of the feed box, and the circular rod is placed on the upper side of another pulley. The upper end of the circular rod is connected to and passes through the feed box and the circular filter plate. A set of evenly arranged dispersing rods is fixedly connected to the outer side of the circular rod. The set of dispersing rods is located on the upper side of the circular filter plate. The corresponding brush plates are fixedly connected to both sides of the circular rod, and a pair of brush plates are located on the lower side of the circular filter plate.

[0009] A further feature of this invention is that the brushes of the pair of brush plates are hard brushes, and the upper ends of the brushes of the pair of brush plates are inserted into the filter holes of the circular filter plate.

[0010] A further feature of this invention is that the bottom of the feed box is sloped, which avoids uneven mixing caused by clumping.

[0011] A further feature of this invention is that a trapezoidal scraper is fixedly connected to the lower end of the shaft, and the trapezoidal scraper fits against the bottom of the tank body.

[0012] A further feature of this invention is that: an annular ring is fixedly connected to the upper end of the trapezoidal scraper, and symmetrical arc-shaped scrapers are fixedly connected to the upper side of the annular ring; the annular ring and the pair of arc-shaped scrapers are fitted into the tank body.

[0013] A further feature of this invention is that all of the stirring blades are installed at an angle to reduce the resistance to stirring.

[0014] A further feature of this invention is that a discharge valve is fixedly connected at the eccentric position at the bottom of the tank.

[0015] A further feature of this invention is that the motor is a slow-speed motor.

[0016] The beneficial technical effects of this utility model are as follows: This utility model pours solid granular raw materials into the feeding box, and pours liquid raw materials and powdered raw materials that are easily soluble in liquid raw materials into the tank through the feeding pipe. When the device is started, the dispersing structure disperses the solid raw materials that are generally soluble and prone to clumping, so that they enter the tank in the form of powder or small particles for stirring, thus avoiding the problem of uneven stirring caused by agglomeration. The hard bristles of the brush rod are used to unclog the filter holes of the circular filter plate to prevent the filter holes from being blocked and affecting the material feeding. During stirring, the trapezoidal scraper and a pair of arc-shaped scrapers make it easy to scrape the raw materials attached to the inner wall of the tank and participate in the stirring. After the material is discharged, it is easy to clean the tank. Attached Figure Description

[0022] The following is a reference to the appendix. Figures 1-4 The preferred embodiments of this utility model are described below. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0023] This utility model proposes a mixing tank for pretreatment of microbial compound fertilizer. When using this device, liquid raw materials and powdered raw materials easily soluble in the liquid are sequentially poured into the tank body 4. Solid raw materials with moderate solubility and prone to clumping are poured into the feed box 1 (solid raw materials can also be poured into the feed box 1 at a uniform speed using an auger, depending on the mixing volume). The motor 9 is started, driving the shaft 6 to rotate. The shaft 6 drives a set of stirring blades 5 to rotate and stir. The shaft 6 drives the corresponding pulley 13 to rotate. One pulley 13 drives another pulley 13 to rotate via a belt 3. The other pulley 13 drives a circular rod 2 to rotate. The circular rod 2 drives a set of dispersing rods 12 and a pair of brush plates 15 to rotate. The brushes of the pair of brush plates 15 slide along the lower side of the circular filter plate 10. The dispersing rods 12 rotate to disperse the clumped solid raw materials. The dispersed powder or small particles fall through the filter holes of the circular filter plate 14 onto the inclined surface at the bottom of the feed box 1. Undispersed raw materials continue to be dispersed. The material continues to be dispersed on the circular filter plate 14. Qualified raw materials slide along the inclined surface into the feed pipe 11 and fall into the tank 4. Simultaneously, a set of brush plates 15 clears the filter holes of the circular filter plate 14 to prevent blockage and ensure proper material feeding. Solid raw materials fall into the tank 4 for stirring. At the same time, the shaft 6 drives the trapezoidal scraper 8 to slide along the bottom of the tank 4. The trapezoidal scraper 8, through the annular ring 7, drives a pair of arc-shaped scrapers 8 to slide along the tank 4. The trapezoidal scraper 8, in conjunction with the pair of arc-shaped scrapers... The scraper 8 scrapes the raw material adhering to the tank 4 and adds it to the mixing process, making the mixing more uniform. After the mixing is finished, the motor 9 is adjusted to a slow speed, and the discharge valve is opened to discharge the mixed compound fertilizer. During discharge, the scraper scrapes the raw material adhering to the tank 4 to avoid waste. After the raw material is discharged, the motor 9 is turned off. When cleaning the pipe 4, the motor 9 is restarted. With the help of the scraper, the raw material adhering to the inner wall of the tank 4 is scraped off, making the cleaning more convenient and reducing the difficulty of cleaning.
