Description

[Detailed description of the invention] The present invention relates to a raw material transfer structure for a rapid fermentation compost production device,
The purpose is to prevent clogging during the transfer process of fermented compost raw materials and achieve consistent transfer.

The rapid fermentation compost production equipment takes out a deep bed of human, livestock, poultry, etc., one or more types of moisture regulators such as sawdust, rice husks, and straw, and a fermentation accelerator from a raw material storage tank containing 0 of each type. The raw materials with uniform properties are sent via a screw conveyor for diagonal soil lifting to a crushing, sorting, mixing device that removes impurities such as stones, crushes nodules, and mixes the raw materials. The kneaded raw materials are taken out and sent to the primary fermentation tank using a screw conveyor for diagonal lifting, and then the raw materials that have completed the primary fermentation are sent to the secondary fermentation storage area. Raw material clogging occurs at the part where the raw material falls from the end of each process to the starting end of the diagonal lifting screw conveyor, that is, the raw material transfer relay part, and continuous raw material transfer cannot be achieved.

Therefore, it is necessary to constantly monitor the raw material transfer relay section.

Furthermore, since the amount of time required to fill the fermentation tank changes due to fluctuations in the amount of transfer, there are drawbacks such as the need to monitor the amount of input into the fermentation tank, which reduces compost production efficiency and increases worker fatigue. is inviting.

The present invention solves the problems of the conventional method because the material to be transferred is a material containing a relatively large amount of water for fermentation, and the angle between the falling path and the diagonal lifting path of the material is an acute angle. This was done by focusing on the fact that the transfer of lifting raw materials is obstructed by falling raw materials O, and from the raw material storage tank to the crushing, sorting and mixing process, primary fermentation process, secondary fermentation and deposition process, etc. In a rapid fermentation compost manufacturing apparatus in which the raw materials taken out from the end of each process are sequentially transferred by a screw conveyor for diagonal lifting, there is a line between the axis of the conveyor and the starting end of the screw conveyor for diagonal lifting. A series of relay screw conveyors are installed that intersect at approximately 90 degrees from above.
The relay screw conveyor is supported at its upper end and has a lower end force aa.
A short compare is driven by a motor with a free end and an upper end support, and the free end of the relay screw conveyor is exposed to the supply port of the diagonal lifting screw conveyor.
The gist of this paper is a raw material transfer structure for a rapid fermentation compost manufacturing apparatus in which raw materials from the end of the process fall into the upper part of a relay screw conveyor.

To explain the present invention in detail with reference to an illustrated example, in FIG.
A is a raw material storage tank, B is a crushing, sorting and mixing process section, and C is a primary fermentation process section.The raw materials that fall to the end of each process section are transferred to the next process section by a needle lifting screw conveyor D. E is a relay screw conveyor interposed between the terminal end of each process section and the diagonal lifting screw conveyor D.

As shown in detail in FIG. 2, this relay screw conveyor E has a screw conveyor 1 with one end supported and the other end free, surrounded by a casing 2, and a deceleration drive motor that controls the screw conveyor 1, with the end being visible. 3, and the casing 2 has a raw material receiving eye 4 that opens upward at an angle of 45 degrees to the axis of the screw conveyor 1, and an opening facing the free end of the screw conveyor that is perpendicular to the axis. It has a configuration in which it is opened to form a delivery port 5.

This relay screw conveyor E has a supply port D1 opened in the starting end case of the diagonal lifting screw conveyor D.
The feed ports 5 are aligned and fixed, and the raw material receiver is interposed by fixing the input hole 4 to the take-out port AH of the process section.

The transfer device configured as described above is such that the raw material falling from the outlet of each process section directly enters the relay screw conveyor E without entering the starting end of the diagonal lifting screw conveyor, and is placed inside the relay screw conveyor E. The material collides with the screw conveyor 1, and is sent to the starting end of the diagonal lifting screw conveyor D by the force in the transfer direction due to its own weight and the transfer force by the screw conveyor 1. Obstruction of the diagonal lifting blades caused by falling material, which occurs when the intersection angle with the axis of the conveyor is acute, is eliminated.

That is, the falling force of the raw material is once absorbed by the screw conveyor 1, and at the same time, it is diverted to the transport direction and becomes low speed, and this is diagonally lifted at an angle of 90 degrees in the transport direction of the screw conveyor D for diagonal lifting. In order to feed the raw material to the starting end of the screw conveyor D, the gap between the falling route of the raw material and the diagonally lifting route is widened, and the falling raw material is supplied at a lower speed without touching the diagonally lifting raw material. This eliminates the reduction in diagonal lifting and transfer force due to mutual contact between the raw materials and the falling blade of the supplied raw materials.

Therefore, if the raw material becomes clogged in the relay section, it can be transferred in a very smooth direction without causing a change in the transfer amount, and therefore, the entire equipment, ie, the entire fermentation tank, can be transferred continuously without having to monitor that section or the content of the fermentation tank. By operating the rapid fermentation compost production device, efficient production of fermentation compost can be achieved.

As described above, according to the present invention, the falling force of the raw materials does not obstruct the lifting blades of the diagonal lifting screw conveyor, thereby preventing the occurrence of raw material clogging at the relay section. Not only that, but also because the lower end, which is the free end, of the relay screw conveyor is exposed to the supply port of the diagonal lifting screw conveyor, the occurrence of raw material clogging can be prevented in advance.

In other words, since a general screw conveyor has a structure in which both ends of the screw are pivotally supported by the end walls at both ends of the casing, the transfer path of the transported object necessarily curves before the end wall, and therefore However, since the relay screw conveyor of the present invention has a free end at the lower end, and there is no end wall of the casing at the lower end, the raw material that is the transported material can accumulate. Instead of accumulating at the bottom of the conveyor, it is sent out straight along the axial direction of the screw and dropped into the next conveyor.

Therefore, the joint with the diagonal lifting screw conveyor can be smoothly connected without any problems.
