Accordingly, the mixed powder filling grooves, having a half cylinder shape, is bound by roller and formed in a shape of granule due to adhesion between mixed powder.

Description

Device for manufacturing granular solid fertilizers {Device for manufacturing granular solid manure}

The present invention relates to a granular solid fertilizer manufacturing apparatus for producing a solid fertilizer (filed as the same as the original) solidified shell shell powder by using elm extract and clay powder as an additive, in particular having a roller to be suitable for mass production A granular solid fertilizer production apparatus.

Conventionally, since there has been no solid fertilizer using shell powder, no apparatus has been used for producing solid fertilizer. However, the extruded manufacturing apparatus shown in FIG. 1 was used to granulate the mixed powder in various fields such as livestock feed, pharmaceuticals, and confectionery. It is soft and can be used only when there is cohesion between particles due to the nature of the mixed powder, but it is a problem to be used to granulate shell powder with sharp edges of powder particles and no cohesion between powder particles (i.e. When mixing and granulating clay powder, the above-mentioned conventional apparatus produces a powder and a problem of low granulation efficiency. Even if a conventional apparatus is used to granulate the pot shell powder, the conventional apparatus is an extrusion method, so that the granulated fertilizer is pushed through the nozzle 123 by pushing the mixed powder 101 by the skews 121. Since the power consumption is considerable and the problem that the nozzle 123 is overheated when operating for a long time, there was a problem that is not suitable for mass production of granular fertilizer.

Accordingly, the applicant has developed a device of the present invention to solve the above problems of the conventional device and to be suitable for mass production of granular solid fertilizers filed with the same.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is to produce a granular solid fertilizer that can be produced in a large amount of granular solid fertilizer by mixing the elm extract and clay powder in shell powder To provide a device.

3 is a detailed view of a roller used in the apparatus of FIG.

4 is a plan view of the roller of the apparatus of FIG.

Figures 5a-5c is a cross-sectional view of the roller showing a process in which the solid fertilizer is produced by the pressure rotation of the roller.

Fig. 6A shows a state in which the mixed powder is contained in the semi-cylindrical grooves of each roller.

Fig. 6B is a view showing a granular solid fertilizer in which the mixed powder contained in each roller is formed into a cylindrical shape by the pressure contact rotation of the roller.

The present invention provides a granule comprising dispensing means for dispensing a mixed powder, granulating means for producing the mixed powder dispersed into granular solid fertilizer, and transporting means for conveying granular solid fertilizer formed by the granulating means. It is a solid solid fertilizer manufacturing apparatus.

In addition, in the granular solid fertilizer production apparatus of the present invention, the granule forming means includes a first roller and a second roller, the first roller and the second roller is constant in the longitudinal direction and the circumferential direction at mutually opposite points Having a plurality of grooves spaced apart from each other, the grooves having a half shape of the granular solid fertilizer such that the granular solid fertilizer is produced by the pressing force of each other at the point where the first roller and the second roller are engaged with each other and rotated. Each can have a.

In the granular solid fertilizer production apparatus of the present invention, the first and second roller grooves preferably have a semi-cylindrical shape.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to Figure 2, the granular production apparatus of the present invention is a mixed powder container (10) containing a mixed powder (11) mixed with shell powder, elm extract and clay powder, and the like to transport the mixed powder Hop conveyor 20, a powder distributor 30 that receives and distributes the mixed powder 11 transported by the hop cone 20, and the mixed powder 11 distributed from the powder distributor 30 It is composed of a granular roller 40 for producing a granular form, a convea 50 for transporting granular fertilizer discharged from the granular roller 40, and a dryer 60 for drying the granular fertilizer.

Since the other components except the granular rollers 41 and 42 are already known techniques before the present application, a detailed description thereof will be omitted, and hereinafter, the granular rollers 41 and 42 may be referred to as features of the present invention. It demonstrates in detail.

3 and 4 are a perspective view and a plan view of the granular roller 40 of the present invention, wherein the granular roller 40 is composed of two rollers (41, 42) which are pressed against each other while rotating at the same speed in the opposite direction to each other do. The plurality of grooves 43 and 44 formed on the surfaces of the rollers 41 and 42 respectively have a half shape of the shape of the granular solid fertilizer to be finally produced and the rollers in the circumferential and longitudinal directions of the rollers 41 and 42. It is formed spaced at regular intervals over the entire surface.

Here, the shape of the grooves 43 and 44 of the roller may include any shape that can achieve the object of the present invention, but preferably has a semi-cylindrical shape.

Figures 5a to 5c is a view showing the operation of the roller for molding the mixed powder 11 into a cylindrical granular solid fertilizer.

Referring to FIG. 5A, the mixed powder 11 dispensed from the powder distributor 30 is supplied between the roller 41 rotating clockwise and the remaining roller 42 rotating counterclockwise, so that each groove ( 43,44).

Referring to FIG. 5B, each of the mixed powders 11 filled in the grooves 43 and 44 is pressed into each other by the pressure welding rotation of the rollers 41 and 42 and formed into a granular solid fertilizer by the adhesive force between the mixed powders. .

Referring to FIG. 5C, the granular solid fertilizer is separated from the grooves 43 and 44 of the roller with the continuous rotation of the rollers 41 and 42 since the cohesive force between the mixed powder is stronger than the adhesion between the mixed powder and the roller. do.

Fig. 6A shows a granular solid fertilizer in which the mixing powder 11 is filled in the rollers 41 and 42 having semi-cylindrical shapes of the grooves 43 and 44, and shaped into semi-cylindrical shapes according to the shape of the grooves.

Fig. 6B shows a granular solid fertilizer in which the semi-cylindrical granular solid fertilizer of Fig. 6A is formed into a cylindrical shape by press-rotating the rollers 41 and 42. Figs.

The granular solid fertilizer production apparatus of the present invention has the effect of solidifying the powdered organic fertilizer using the shell powder.

In addition, the manufacturing apparatus of the present invention has less power consumption compared to the conventional extrusion manufacturing apparatus and there is no problem of overheating the device, so that it is possible to manufacture a large amount of granular solid fertilizer, so it is easy to process the shell wastes that are discarded in the beaches all over the country. It has the effect of preventing environmental pollution.
