Abstract
The invention discloses a middle part structure of a spraying granulation dryer. The middle part structure comprises a machine body; one end of the machine body is connected with a hierarchical cone, and a machine body cavity arranged at the other end of the machine body is internally provided with a guide plate; a middle check ring is arranged in the middle of the wall of the machine body inner cavity; two return spiral bodies are respectively arranged at the two sides of the middle check ring; the machine body inner cavity is internally provided with a shoveling plate. The middle part structure of the spraying granulation dryer is simple and is convenient to operate; the machine body is internally provided with the shoveling plate, so that a uniform material curtain is formed by material; slurry and compressed air are sprayed into the machine body by a spray gun and are evenly stuck with the fine particles in the material curtain, the mixture is dried to form granular products, and the granular products are finally screened and treated by a polygonal rotary screen; in the whole production process, the artificial loss is minimized, and the product quality is greatly improved.
Description
Technical field
The present invention relates to compound fertilizer producing equipment, be specifically related to a kind of spray granulation drier central structure.
Background technology
comminutor and drying machine are requisite equipment in composite heat transfer process; comminutor is mainly used in finished product or semi-finished product fertilizer to extrude; reach product quality requirement; drying machine is used for the material produced in comminutor to carry out drying; material is carried out in current industry granulating and drying to have to pass through above-mentioned two multiple steps of machine and come; because its intermediate link is too much, thus cause artificial loss large, product quality is not high.
Summary of the invention
The object of invention: in order to solve the deficiency having now technology, the invention provides a kind of spray granulation drier central structure.
Technical scheme: a kind of spray granulation drier central structure, described spray granulation drier central structure comprises body, one end of described body connects classfied cone, stock guide is provided with in the body chamber of the other end of described body, middle back-up ring is provided with in the middle part of described body internal chamber wall, described middle back-up ring both sides are provided with returning charge conveyor screw, are provided with flight in described body inner chamber.
As preferably, described classfied cone inside is provided with polygonal rotary screen.
Beneficial effect: a kind of spray granulation drier central structure of the present invention, structure is simple, easy to operate, is provided with flight in body, material shape can be made uniformly to expect curtain, slip and compressed air spray in body by spray gun, be bonded together, and form granular product through super-dry with the thin shape in material curtain is evengranular, screening process is carried out eventually through polygonal rotary screen, in whole production process, artificial loss is dropped to minimum, improve product quality greatly again simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Embodiment:
As shown in Figure 1, a kind of spray granulation drier central structure, comprise body 1, one end of described body 1 connects classfied cone 7, stock guide 5 is provided with in the body chamber of the other end of described body 1, be provided with middle back-up ring 4 in the middle part of described body 1 internal chamber wall, described middle back-up ring 4 both sides are provided with returning charge conveyor screw 2, are provided with flight 3 in described body 1 inner chamber; Described classfied cone 7 inside is provided with polygonal rotary screen 6.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
