Description

Technical Field

[0001] This utility model belongs to the field of fertilizer production technology, specifically a coating material mixing device for slow-release pH-adjusting fertilizers. Background Technology

[0002] Slow-release pH-regulating fertilizers are key products for the synergistic development of "reducing fertilizer use and increasing efficiency" and "soil improvement" in modern agriculture. Their core technology lies in achieving two major goals through a functional coating layer: first, controlling the slow release of nutrients such as nitrogen, phosphorus, and potassium to match the nutrient requirements of crops throughout their entire growth cycle and reduce nutrient leaching and volatilization losses; second, gradually improving soil acidification or salinization problems through the long-term release of pH-regulating active ingredients in the coating layer, creating a suitable pH environment for crop roots. The performance of the coating layer directly depends on the mixing quality of the coating material, therefore, the performance of the mixing device selected during the mixing of the coating material is also particularly important.

[0003] However, currently, commonly used membrane material mixing devices often encounter problems when mixing coating raw materials. These raw materials include both powdered and liquid materials, such as binders and plasticizers. Due to the different states of these materials, the mixing devices typically only have one inlet for both powdered and liquid materials. This prevents simultaneous feeding of the powdered and liquid materials. Furthermore, the powdered materials tend to float inside the mixing drum after being poured in, preventing some of them from mixing with the liquid materials and thus affecting the mixing efficiency. Utility Model Content

[0004] This invention provides a mixing device for coating materials of slow-release pH-adjusting fertilizers, which can effectively solve the problem of uneven mixing caused by the inability of powdered and liquid materials in the coating raw materials to be fed synchronously during the mixing process in existing mixing devices: A mixing device for coating materials of slow-release pH-adjusting fertilizers includes a mixing drum for mixing coating materials. A powder feeding mechanism is installed on the top of the mixing drum, and a liquid storage tank is fixedly installed on the top of the mixing drum near the powder feeding mechanism. A pump box for conveying liquid raw materials inside the liquid storage tank is installed on one side of the mixing drum. A powder discharge chute is opened on the top of the mixing drum, and a guide plate is installed inside the mixing drum, located below the discharge chute. A liquid outlet pipe is installed at the discharge end of the pump box, and the end of the liquid outlet pipe passes through one side of the guide plate and is fixedly connected to a transverse pipe. Several rows of oblique nozzles facing the other side of the guide plate are installed on the outside of the transverse pipe.

[0005] As a further technical solution of this utility model, one side of the guide plate is vertically arranged and the other side is inclined. The feeding trough is located above the inclined section of the guide plate, and a horizontal slot is connected between the inclined section and the vertical section.

[0006] As a further technical solution of this utility model, a stirring shaft is installed inside the stirring cylinder, and a stirring motor for driving the stirring shaft is installed at the bottom center of the stirring cylinder.

[0007] As a further technical solution of this utility model, the height of the top of the stirring shaft is less than the height of the bottom of the guide plate, and a scraper is installed at the bottom of the stirring shaft.

[0008] As a further technical solution of this utility model, a discharge pipe is also installed at the bottom of the mixing drum. The discharge pipe is located on one side of the mixing motor and is connected to the interior of the mixing drum.

[0009] As a further technical solution of this utility model, the top of the liquid storage tank is equipped with a liquid inlet connector, and a liquid inlet pipe is connected between one side of the liquid storage tank and the suction end of the pump box.

[0010] As a further technical solution of this utility model, the powder feeding mechanism includes a mounting plate, a conveying auger is mounted on one side of the mounting plate, and a feeding port is fixedly mounted on the outside of the conveying auger. A discharge pipe is fixedly connected to the end of the conveying auger, and a drive motor for driving the spiral blades of the conveying auger is mounted on the other side of the mounting plate.

[0011] As a further technical solution of this utility model, the mounting plate is L-shaped, and one side of its horizontal section is fixedly connected to the outer wall of the mixing cylinder.

[0012] As a further technical solution of this utility model, a support plate is also fixedly connected to the bottom of the mounting plate. The support plate is inclined, and its end away from the mounting plate is fixedly connected to the outer wall of the mixing cylinder.

[0013] As a further technical solution of this utility model, the feeding pipe is interconnected with the inside of the mixing drum, and it is set perpendicular to the conveying auger, with the bottom of the feeding pipe aligned with the inside of the feeding trough.

[0014] The beneficial effects of this utility model are as follows: By adopting a method of simultaneous feeding of powdered and liquid raw materials, this utility model can effectively improve the mixing efficiency of the mixing device. As the powdered raw materials enter the mixing drum, the liquid raw materials are sprayed through the inclined nozzles to contact them, achieving preliminary mixing of the powdered and liquid raw materials. This effectively avoids the problem of insufficient contact of raw materials due to long settling time during feeding of powdered raw materials, and greatly avoids the problem of powdered raw materials floating inside the mixing drum and failing to mix with liquid raw materials. Furthermore, the guide plate is set up to guide the premixed powdered and liquid raw material mixture to the lower part of the mixing drum for stirring, further improving the mixing efficiency of the coating material.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-3 As shown, a coating material mixing device for slow-release pH-adjusting fertilizer includes a mixing drum 1 for mixing the coating material. A powder feeding mechanism 2 is installed on the top of the mixing drum 1, and a liquid storage tank 4 is fixedly installed on the top of the mixing drum 1 near the powder feeding mechanism 2. A pump box 3 for conveying liquid raw materials inside the liquid storage tank 4 is installed on one side of the mixing drum 1. A powder discharge trough 10 is opened on the top of the mixing drum 1, and a guide plate 9 is installed inside the mixing drum 1. The guide plate 9 is located below the discharge trough 10. A liquid outlet pipe 11 is installed at the discharge end of the pump box 3. The end of the liquid outlet pipe 11 passes through one side of the guide plate 9 and is fixedly connected to a transverse pipe 12. Several rows of oblique nozzles 13 facing the other side of the guide plate 9 are installed on the outside of the transverse pipe 12.

[0020] Specifically, the powder is conveyed by the powder feeding mechanism 2, while the pump box 3 conveys the liquid raw material from the storage tank 4 to the inside of the mixing drum 1. The liquid raw material is sprayed out by the inclined nozzle 13 and comes into contact with the powder from the feed trough 10, thereby causing the powder to settle quickly and preventing the powder from floating inside the mixing drum 1.

[0021] One side of the guide plate 9 is vertically arranged, and the other side is inclined. The feed chute 10 is located above the inclined section of the guide plate 9, and a horizontal slot connects the inclined section and the vertical section. By setting the horizontal slot, the mixture of powder and liquid raw materials can be quickly discharged from its interior into the mixing drum 1 for mixing.

[0022] The mixing drum 1 is equipped with a stirring shaft 7, and a stirring motor 5 for driving the stirring shaft 7 is installed at the center of the bottom of the mixing drum 1.

[0023] The top height of the stirring shaft 7 is less than the bottom height of the guide plate 9, and a scraper is installed at the bottom of the stirring shaft 7. A discharge pipe 6 is also installed at the bottom of the stirring drum 1. The discharge pipe 6 is located on one side of the stirring motor 5 and is connected to the inside of the stirring drum 1. As the stirring shaft 7 rotates, the scraper scrapes the bottom of the stirring drum 1, which facilitates the quick discharge of the mixed coating material into the inside of the discharge pipe 6 and prevents the raw material from remaining at the bottom of the stirring drum 1 later.

[0024] The top of the storage tank 4 is equipped with a liquid inlet connector, and a liquid inlet pipe 8 is connected between one side of the storage tank 4 and the suction end of the pump box 3. The liquid inlet connector facilitates the delivery of liquid raw materials into the interior of the storage tank 4.

[0025] The powder feeding mechanism 2 includes a mounting plate 201. A conveying auger 202 is mounted on one side of the mounting plate 201, and a feeding port 204 is fixedly mounted on the outside of the conveying auger 202. A discharge pipe 203 is fixedly connected to the end of the conveying auger 202. A drive motor 205 for driving the spiral blades of the conveying auger 202 is mounted on the other side of the mounting plate 201. The mounting plate 201 is L-shaped, and one side of its horizontal section is fixedly connected to the outer wall of the mixing drum 1. A support plate 206 is also fixedly connected to the bottom of the mounting plate 201. The support plate 206 is inclined, and its end away from the mounting plate 201 is fixedly connected to the outer wall of the mixing drum 1. The discharge pipe 203 communicates with the inside of the mixing drum 1 and is perpendicular to the conveying auger 202. The bottom of the discharge pipe 203 is aligned with the inside of the discharge trough 10.

[0026] Specifically, the powder enters through the feed port 204, is conveyed by the conveying auger 202 to the inside of the discharge pipe 203, and then enters the guide plate 9 through the discharge chute 10, thereby realizing the feeding operation of the powder.

[0027] A coating material mixing device for slow-release pH-adjusting fertilizers is used in which the powder of the coating material is fed into the feed port 204 and enters the interior of the conveying auger 202. Then, driven by the drive motor 205, the conveying auger 202 transports the powder to the discharge pipe 203 and then into the interior of the mixing drum 1 through the discharge trough 10.

[0028] Meanwhile, the pump box 3 draws the liquid raw material from the coating material in the storage tank 4 into the outlet pipe 11, then into the horizontal pipe 12, and then sprays it outward through multiple inclined nozzles 13. The inclined nozzles 13 face the inclined section of the guide plate 9. As the powder enters through the feed chute 10, the liquid raw material sprayed by the inclined nozzles 13 comes into contact with the powder, thereby causing the powder to settle quickly and achieving the initial mixing of the powder and liquid raw material. As the inclined nozzles 13 continuously spray liquid raw material, the mixed liquid raw material and powder mixture falls down along the inclined surface of the guide plate 9 to the lower part of the mixing drum 1. The stirring motor 5 drives the stirring shaft 7 to continuously stir, thereby achieving the mixing operation.

[0029] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
