Description

Technical Field

[0001] This utility model relates to the field of silicon fertilizer preparation technology, specifically a heater used in the silicon fertilizer preparation process. Background Technology

[0002] Silicon fertilizer is a high-quality, health-promoting, and plant-regulating fertilizer, a novel multifunctional fertilizer unmatched by other chemical fertilizers. It can be used both as a fertilizer to provide nutrients and as a soil conditioner to improve soil quality. Furthermore, it also has disease-preventing, insect-controlling, and toxicity-reducing effects. In the production process of silicon fertilizer, drying and dehydration are often required, necessitating the use of heating equipment to reduce its moisture content.

[0003] Chinese patent CN219502464U discloses a silicon-containing fertilizer production device, comprising a mixing cylinder body. A partition is fixed between the inner walls of the mixing cylinder body. Multiple support rods are fixed near the bottom edge of the inner walls of the mixing cylinder body. A motor is fixed between one end of each support rod. A connecting block is fixed to the output end of the motor. The top of the connecting block rotates through to the top of the partition. A rotating shaft is fixed to the top of the connecting block. Spiral blades and a stirring rod are fixed to the outer surface of the rotating shaft. This invention, by fixing both the spiral blades and the stirring rod to the rotating shaft, allows the rotating shaft to simultaneously stir and mix the fertilizer inside the mixing cylinder body, resulting in a more uniform mixture. Simultaneously, the stirring of the spiral blades creates downward pressure on the fertilizer inside the mixing cylinder body, facilitating its subsequent flow out through the partition.

[0004] However, the patent relies solely on the heating resistance wire installed on the side wall of the mixing cylinder to heat the silicon fertilizer in the inner cavity, which results in slow heating of the silicon fertilizer. At the same time, the slow heating makes the silicon fertilizer easy to condense on the spiral blades, which will reduce the mixing efficiency of the spiral blades over time. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical problems and provide a heater for preparing silicon fertilizer that provides uniform and rapid heating, uniform stirring, and prevents material from condensing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows.

[0007] A heater for preparing silicon fertilizer, the heater comprising a cylindrical tank 1 and a stirring shaft 2;

[0008] The cylindrical tank 1 is closed at both ends; an axial stirring shaft 2 is provided inside the cylindrical tank 1, one end of the stirring shaft 2 passes through the top of the cylindrical tank 1 and is connected to the output end of the stirring motor 3, and the other end of the stirring shaft 2 is rotatably connected to the bottom of the cylindrical tank 1.

[0009] Several U-shaped stirring rods 4 are spirally arranged on the stirring shaft 2.

[0010] Furthermore, a rotating conductive slip ring 6 is provided at the part of the stirring shaft 2 that protrudes from the top of the cylindrical tank 1;

[0011] The U-shaped stirring rod 4 is equipped with a first resistance wire 7 inside, which is connected to the rotating conductive slip ring 6.

[0012] Furthermore, a protective support cover 5 is installed on the top surface of the cylindrical tank 1, and a stirring motor 3 is fixed on the top surface of the protective support cover 5. A rotating conductive slip ring 6 is disposed inside the protective support cover 5.

[0013] Furthermore, a wire 61 passes through the rotating conductive slip ring 6, with the upper part of the wire 61 extending out of the protective support cover 5 and connected to the power supply equipment, and the lower part of the wire 61 passing into the stirring shaft 2 and connected to the first resistance wire 7.

[0014] Furthermore, the sidewall of the cylindrical tank 1 is provided with several turns of second resistance wire 8, which are electrically connected to the power supply equipment.

[0015] Furthermore, a third resistance wire 10 is provided on the outer side of the bottom of the cylindrical tank 1, and the third resistance wire 10 is electrically connected to the power supply equipment.

[0016] Furthermore, the first resistance wire 7, the second resistance wire 8, and the third resistance wire 10 are connected in parallel.

[0017] Furthermore, the side walls and bottom outer surfaces of the cylindrical tank 1 are covered with a heat insulation layer 9.

[0020] This utility model provides a heater for preparing silicon fertilizer. The combination of a first resistance wire, a second resistance wire, and a third resistance wire heats the material in the columnar tank from all directions. This not only ensures that the silicon fertilizer is heated evenly but also greatly increases the heating speed. It also prevents the silicon fertilizer from condensing and solidifying on the U-shaped stirring rod or the columnar tank due to slow heating.

[0021] This utility model provides a heater for preparing silicon fertilizer. The U-shaped stirring rod for stirring is spirally distributed on the outer surface of the stirring shaft, which allows for more thorough stirring of the silicon fertilizer, achieving rapid and uniform mixing. It also eliminates eddies.

[0022] The present invention provides a heater for preparing silicon fertilizer. The heat insulation layer can limit the heat transfer direction of the second and third resistance wires, and prevent the heat of the second and third resistance wires from being lost to the outside of the columnar tank, thereby accelerating the internal heating of the mixture and further improving the processing efficiency of silicon fertilizer.

A first resistance wire 7 is provided inside each U-shaped stirring rod 4 and is connected to the rotating conductive slip ring 6. The U-shaped stirring rods 4 are spirally distributed on the outer surface of the stirring shaft 2, which can make the silicon fertilizer more thoroughly stirred and achieve the purpose of rapid and uniform stirring. The rotating conductive slip ring 6 is provided to prevent the first resistance wire 7 from getting tangled during rotation, so that the first resistance wire 7 can still rotate even when connected to the wire 61.

[0033] A protective support cover 5 is installed on the top surface of the cylindrical tank 1. A stirring motor 3 is fixed to the top surface of the protective support cover 5. A rotating conductive slip ring 6 is housed inside the protective support cover 5. Because the rotating conductive slip ring 6 requires a certain degree of precision, the protective support cover 5 serves two purposes: firstly, it protects the rotating conductive slip ring 6 from malfunction in environments with high dust content; secondly, it provides support for the stirring motor 3. A wire 61 runs through the rotating conductive slip ring 6. The upper part of the wire 61 extends out of the protective support cover 5 and connects to the power supply equipment, while the lower part of the wire 61 passes through the stirring shaft 2 and connects to the first resistance wire 7.

The first resistance wire 7, together with the second resistance wire 8, heats the silicon fertilizer in the cylindrical tank 1 from all directions, which can not only make the silicon fertilizer heat evenly, but also greatly improve the heating speed, and prevent the silicon fertilizer from condensing and solidifying on the U-shaped stirring rod 4 or the cylindrical tank 1 due to slow heating.

[0035] The side walls and bottom surface of the cylindrical tank 1 are covered with a heat insulation layer 9. Both the cylindrical tank 1 and the U-shaped stirring rod 4 are made of heat-conducting material. Specifically, the heat insulation layer 9 can limit the heat transfer direction of the second resistance wire 8, preventing the heat of the second resistance wire 8 from being lost to the outside of the cylindrical tank 1, thereby accelerating the heating inside the cylindrical tank 1.

A temperature sensor is provided in the cylindrical tank 1. After the silicon fertilizer is stirred evenly and heated to the set value of the temperature sensor, the discharge valve 13 is opened, allowing the silicon fertilizer to flow out and proceed to the next step of processing.
