Problems solved by technology

[0005] The purpose of the present invention is to make the mixing between the fermented material and other materials more fully through the reverse stirring of the upper and lower layers, layered stirring, horizontal stirring and vertical turning through the function of the rotating sleeve. The protruding length of the column is controllable, which makes it easier for the motor to rotate when driving the stirring structure on the rotating shaft. The adjustment solution added in the sleeve is mixed with the fermentation material, which will not affect the activity of microorganisms, and solve the problems of uneven stirring of the fermentation material inside the fermenter, the obstruction of the start of the motor driving the stirring structure, and the failure of pH adjustment to affect the microbial activity. And propose a kind of microbial solid-state fermentation equipment based on organic bacterial fertilizer

Embodiment 1

[0033] see Figure 1-4As shown, a microbial solid-state fermentation device based on organic bacterial fertilizer includes a fermenter body 1 and a rotating shaft 2. The middle position of the upper surface of the fermenter body 1 is rotatably connected to the rotating shaft 2, and the outer wall of the rotating shaft 2 is close to the fermenter body. 1 is internally connected with a connecting frame 35, one end of the connecting frame 35 is connected to the outside of the rotating shaft 2, and the other end is connected to the sliding ring 32 at the corresponding position, so that the rotation of the rotating shaft 2 can drive the sliding ring 32 to rotate, and the fermenter body 1. There are several evenly distributed slide rails 31 connected to the inner side wall. A sliding ring 32 is slidably connected to the position corresponding to the connecting frame 35 inside the sliding rail 31. The inner wall of the sliding ring 32 is connected to a number of evenly distributed con...

Embodiment 2

[0037] see Figure 5-7 As shown, the outer wall of the rotating sleeve 34 is connected with several evenly distributed sealing gaskets 41, the outer wall of the rotating sleeve 34 is slidably connected with the stirring column 42 at the position corresponding to the sealing gasket 41, and the rotating sleeve 34 is provided with a sliding hole at the position corresponding to the stirring column 42. , the outer wall of the stirring column 42 is close to the inside of the rotating sleeve 34 and is provided with a return spring 43. When the stirring column 42 slides outward, the return spring 43 is stretched, so that the return spring 43 can be driven to stretch out under the action of self-resetting. The stirring column 42 is retracted inside the rotating sleeve 34, and the external end of the retracted stirring column 42 is flat with the surface of the sealing gasket 41 on the outer wall of the rotating sleeve 34, and the connecting rod 33 is connected with a center limit column...

Embodiment 3

[0041] see Figure 8-9As shown, the inner lower surface of the fermenter body 1 is connected to the position corresponding to the rotating shaft 2 with a filling sleeve 51 , and the inside of the liquid filling sleeve 51 is rotatably connected to a connecting shaft 52 at a position corresponding to the rotating shaft 2 . The connecting shaft 52 is connected to the rotating shaft 2 for rotation. The outer wall of the connecting shaft 52 is integrally formed with a rotating block 55 at the middle position corresponding to the liquid filling sleeve 51. An insulating plate 510 is connected to one side of the outer wall of the rotating block 55. One end of the insulating plate 510 is The inclination angle design makes it easier for the insulating plate 510 to be inserted between the two metal shrapnels in the metal shrapnel group 54 during the rotation process with the rotating block 55, and a support plate 59 is connected to the inside of the liquid filling sleeve 51 close to the r...

Abstract

The invention relates to a solid-state fermentation technology, aims to solve the problems that fermentation materials in a fermentation tank are non-uniformly stirred, starting of a motor for driving a stirring structure to rotate is blocked, pH value regulation is not timely, and microbial activity is affected, and particularly relates to microbial solid-state fermentation equipment based on organic bacterial manure. A rotating shaft is rotationally connected to the middle position of the upper surface of the fermentation tank body; through the action of the rotating sleeve, fermentation materials and other materials are mixed more sufficiently through reverse stirring, layered stirring, transverse stirring and vertical overturning of the upper layer and the lower layer, the extension length of a stirring column on the outer side of the rotating sleeve is controllable, and a motor rotates more easily when driving a stirring structure on a rotating shaft; the condition that starting of the motor is blocked due to large blocking acting force is avoided, and the activity of microorganisms is not affected by mixing the adjusting liquid added through the rotating sleeves distributed on all the layers in the fermentation tank body with the fermentation materials.

Description

technical field [0001] The invention relates to solid-state fermentation technology, in particular to a microbial solid-state fermentation equipment based on organic bacterial fertilizer. Background technique [0002] Solid-state fermentation is the fermentation method of microorganisms on a solid substrate with no or almost no free water. The three phases of gas, liquid and solid coexist in the solid substrate, that is, the porous solid substrate contains water and water-insoluble substances; [0003] In the prior art, during the fermentation process of the solid-state fermentation material inside the fermenter body, in order to ensure that the solid-state fermentation material is fully mixed with other additives during the fermentation process, the fermentation process inside the fermenter body is often carried out during the fermentation process. The material is stirred by a single stirring shaft, the stirring effect is poor, it is difficult to fully mix the fermented mat...
