Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of slow-release fertilizers, in particular to a feeding device used for producing slow-release fertilizers. Background Art

[0002] One of the commonly used production and processing methods for slow-release fertilizers is to coat the surface of water-soluble fertilizer particles with a semi-permeable or insoluble coating, so that the coated water-soluble fertilizer particles have the characteristic of slowly releasing nutrients.

[0003] In order to make the coating material evenly coated on the surface of the fertilizer particles, the coating material is usually dissolved in a solvent; then the fertilizer particles are stirred while the solvent containing the coating material is sprayed. While stirring, the fertilizer particles are heated to dry the solvent, so that the coating material remains on the surface of the fertilizer particles.

[0004] In the prior art, when mass-producing slow-release fertilizers, fertilizer particles are generally put into a large horizontal mixing tank for mixing. In order to improve the drying efficiency, an annular insulation chamber is set along the outer circumference of the mixing tank; on this basis, in order to simplify the structure and facilitate later control and maintenance, the feeding port is usually set at one end of the mixing tank in the horizontal direction. At the same time, a feed guide pipe extending to the feeding port is set at the bottom of the hopper or tank to feed the fertilizer particles into the mixing tank. This brings some problems: the feed guide pipe will not only prevent the staff from observing the situation in the mixing tank from the feeding port, but also prevent the staff from entering the mixing tank for inspection and maintenance; and setting the feed guide pipe small will not only affect the feeding efficiency, but also may cause fertilizer particles to be blocked. Summary of the invention

[0005] The utility model aims to provide a feeding device for producing slow-release fertilizers, which is provided with a material guide pipe that can be easily disassembled and assembled; in this way, the material guide pipe can be set to be thicker to ensure feeding efficiency and avoid blockage; at the same time, it will not hinder staff from observing or entering and exiting from the feeding port.

Of course, according to the actual situation requirements, when it is necessary to feed materials into the mixing tank in batches, the hopper 2 can play the role of temporarily storing fertilizer particles by closing the valve.

[0042] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that without departing from the principle and essence of the present invention, various changes or modifications can be made to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
