Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for producing water-soluble fertilizers. Background Art

[0002] Water-soluble fertilizer refers to compound fertilizers containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid, etc. that can be completely dissolved in water. Compared with traditional superphosphate, granulated compound fertilizers and other varieties, water-soluble fertilizers have obvious advantages. It is a quick-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water and can be directly absorbed and utilized by the roots and leaves of crops. The use of water and fertilizer at the same time, with water carrying fertilizer, has achieved water and fertilizer integration. Its effective absorption rate is more than double that of ordinary chemical fertilizers, reaching 80%-90%; and the fertilizer effect is fast, which can meet the nutritional needs of high-yield crops during the rapid growth period. The water requirement of the drip irrigation system is only 30% of that of ordinary chemical fertilizers, and the fertilization operation can be almost labor-free, which greatly saves labor costs.

[0003] In the field of water-soluble fertilizer production technology, in order to allow various nutrient elements in the water-soluble fertilizer to blend with each other, a constant temperature stirring device is required for uniform mixing. However, the existing stirring devices used for the production of high-efficiency water-soluble fertilizers cannot achieve a constant temperature, and the temperature fluctuates, which easily causes the problem of insufficient reaction of the water-soluble fertilizer.

[0004] The prior art discloses a patent with a publication number of CN213590264U. The solution includes a stirrer housing, a thermocouple sensor is fixedly connected to the middle of the inner wall at the top of the stirrer housing, a processor is arranged on the right side of the thermocouple sensor, a timer is arranged on the left end of the thermocouple sensor, a heating tube is fixedly connected to the inner surface of the insulation layer, a number of heating molybdenum wires are arranged in the heating tube, and push doors are slidably connected to the left and right sides of the bottom of the stirrer housing. The thermocouple sensor monitors the temperature inside the stirrer housing in real time. If the temperature is low, the processor controls the heating molybdenum wire to heat. At the same time, the inner surface of the silicone shock-absorbing layer is fixedly connected to the insulation layer. When the stirring time is up, the processor controls the hydraulic pump station to output hydraulic oil to the hydraulic cylinder. The hydraulic oil pushes the piston rod to move, thereby pushing open the push door, so that the stirred material automatically falls into the discharge trough, and the stirring time is automatically controlled.

[0005] As the existing devices are used, the shortcomings of the technology are gradually exposed, mainly in the following aspects:

[0006] First, after the mixing box keeps the water-soluble fertilizer raw materials at a constant temperature, due to the high viscosity of the materials after constant temperature, it is limited by the influence of the stirring assembly at the bottom of the mixing box, so that a large amount of materials will remain in the mixing box at the end of discharging, affecting the thoroughness of discharging.

[0007] Second, after the mixing box keeps the water-soluble fertilizer raw materials at a constant temperature, the materials tend to adhere to the inner wall of the box due to their greater viscosity after constant temperature, affecting the discharge of the materials.
