Description

Technical Field

[0001] The invention relates to the technical field of fermentation, and in particular to a microbial fertilizer fermentation device. Background Art

[0002] In the fermentation process of microbial fertilizers, the raw materials are diverse, mainly divided into microbial agents and organic materials, among which the microbial agents mainly include Bacillus, yeast, actinomycetes, etc., and the organic materials mainly include livestock and poultry manure, corn stalks, vegetable residues, etc. No matter what the fermentation raw materials are, the fermentation raw materials need to be soaked in fermentation liquid in a tank to achieve fermentation.

[0003] During the fermentation process, due to the accumulation of fermentation raw materials, only the fermentation raw materials accumulated on the outer layer can be effectively fermented, which leads to the inability of all fermentation raw materials to be effectively fermented, resulting in uneven fermentation, affecting the fermentation quality, and causing deviations in the quality of the fertilizer after fermentation of the fermentation liquid. In addition, when the fermentation is completed and the fermentation liquid is discharged, the fermentation raw materials will accumulate in the filter bag under the action of gravity, resulting in the inability to discharge the internal moisture of the accumulated fermentation raw materials in time, and the residual fermentation liquid will be mixed with the subsequent fermentation liquid, thereby affecting the fermentation quality of different batches. At the same time, when the staff takes out the fermentation raw materials from the fermentation barrel, the moisture in the fermentation raw materials cannot be discharged in time, and the fermentation raw materials that are not completely discharged during the process of being taken out will drip, resulting in a waste of fermentation liquid. The dripping fermentation liquid will also pollute the surrounding equipment and environment, reducing the utilization rate of the fermentation liquid after fermentation. Summary of the invention

The magnetic poles on the near side are opposite, and the bottom of the movable rod 612 is fixedly connected to a connecting ring 614, and the bottom of the top cover 3 is fixedly connected to two storage tanks 615. The top of the storage tank 615 passes through the top cover 3, and the bottom of the storage tank 615 is set to be funnel-shaped. The upper surface of the connecting ring 614 is fixedly connected to a movable plug 616, and the top of the movable plug 616 slides inside the storage tank 615. The top of the movable plug 616 is set to be conical, and the top outer ring surface of the movable plug 616 is tightly fitted with the bottom of the inner cavity of the storage tank 615.

[0046] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0047] The initial state is:

[0048] The discharge pipe 2 is not opened, the fixed cover 41 is not threadedly connected to the top cover 3, the spring 1 45 is not stretched by the swing rod 46, the swing rod 57 is not squeezed, and the swing rod 57 is in a tilted state, so that the torsion spring 58 is not elastically tightened, the pressing plate 511 is not squeezed and is in the highest position, the pressing plate 511 makes the spring 2 510 not compressed, the pressing plate 511 makes the squeezing plate 513 fit the lower surface of the fixed cover 41 through the squeezing plate 513, the sealing cover 61 is not threadedly connected to the fermentation tank body 1, in addition, the spring 3 67 is not compressed by the piston plate 68, the magnet 1 69 is not magnetically attracted to the magnet 2 613, and at this time the connecting ring 614 makes the top of the movable plug 616 be in the lowest position inside the storage tank 615.

[0049] During use, the staff first puts the defoaming agent into the storage tank 615 from the top thereof. Since the top of the movable plug 616 is at the lowest position of the inner cavity of the storage tank 615 at this time, the movable plug 616 is in a blocked state with the bottom of the storage tank 615, and the defoaming agent put into the storage tank 615 will not leak out from the bottom of the storage tank 615. Then the staff puts water into the interior of the fermentation tank body 1, and then uses a filter bag to hold the soaked biological bacteria. At this time, the staff can hold the motor 42, insert the stirring shaft 43 into the biological bacteria in the filter bag, and then put the bag mouth of the filter bag on the rotating disk 52, so that the bag mouth of the filter bag can be hooked on the needle 55, and the needle 55 is inserted into the bag mouth of the filter bag, so that the filter bag can be initially and quickly fixed on the rotating disk 52, and it can also be convenient for subsequent removal.

[0050] Installation of stirring components and feeding components:

[0051] The staff inserts the stirring shaft 43 wrapped with the filter bag into the interior of the fermentation tank body 1 through the placement hole in the middle of the top cover 3, so that the biological bacteria in the filter bag are immersed in the water, and the fixing cover 41 is threadedly connected to the top cover 3 by means of threads, thereby achieving the fixation of the fixing cover 41 and the motor 42. Then the staff threadably connects the sealing cover 61 to the top of the fermentation tank body 1 by means of threads. During the threaded installation of the sealing cover 61, the sealing cover 61 will push the pushing ring 63 downwards through the buffer ring 62 to push the pressing plate 511 downwards, so that the pressing plate 511 moves downwards to compress the spring 2 510, and at the same time, the pressing plate 511 will also be driven by the connecting rod 512 The movable extrusion plate 513 moves downward, and the downward movement of the extrusion plate 513 pushes the swing rod 57, so that the swing rod 57 swings downward with the hinge seat 56 as the axis. During the downward swinging of the swing rod 57, the torsion spring 58 is elastically tightened. In addition, the swing rod 57 also drives the second puncture needle 59 to move downward and penetrate into the bag opening of the filter bag sleeved on the rotating disk 52. The puncture-type fixation of the second puncture needle 59 can prevent the filter bag from rotating during the subsequent stirring process. At the same time, it is also convenient for the subsequent fixing tube 44 to effectively stir the biological bacteria in the filter bag, and can also prevent the filter bag from detaching from the rotating disk 52 during the subsequent stirring process, thereby ensuring the firmness of the fixed filter bag.

[0052] At the same time, after the sealing cover 61 is threadedly installed, the sealing plate 65 at the bottom of the pressure relief shell 64 can be attached to the upper surface of the top cover 3, and the sealing plate 65 can block the top of the storage tank 615 to prevent external gas from flowing from the storage tank 615 to the interior of the fermentation tank body 1, thereby preventing external air from affecting the fermentation of biological bacteria inside the fermentation tank body 1. After the sealing cover 61 is threadedly installed, the pressure relief shell 64 will be roughly aligned with the opening 610, which can ensure that the gas inside the fermentation tank body 1 passes through the opening 610 and only enters the interior of the pressure relief shell 64, and at the same time, magnet 1 69 will be magnetically attracted to magnet 2 613.

[0053] The stirring component assists the fermentation of biological bacteria:

[0054] During the fermentation of biological bacteria, the staff can start the motor 42, and the motor 42 drives the stirring shaft 43 to rotate. During the rotation, the stirring shaft 43 will drive the fixed tube 44 to stir the biological bacteria in the filter bag. In addition, during the process of the fixed tube 44 rotating and stirring the biological bacteria, the swing rod 46 will be thrown out to the outside of the fixed tube 44. During the process of the swing rod 46 being thrown out, the spring 45 will be stretched. The swing rod 46 is thrown out only to expand the range of stirring. If the swing rod 46 is affected by the excessive biological bacteria, it will not affect the normal stirring of the biological bacteria by the fixed tube 44. When the biological bacteria immersed in the water are too thin due to the increase of water, the swing rod 46 can also be thrown out normally. The stirring of the biological bacteria by the fixed tube 44 can prevent the accumulation of biological bacteria during the fermentation process, and can also prevent the problem of biological bacteria agglomeration, thereby ensuring the uniformity of biological bacteria fermentation and improving the fermentation quality of biological bacteria.

[0055] During the rotation of the stirring shaft 43, the stirring shaft 43 will drive the fixed ring 51 to rotate. Because the extrusion plate 513 conflicts with the swing rod 57 and cooperates with the limit bar to limit the swing rod 57, the swing rod 57 makes the hinge seat 56 keep the rotating disk 52 fixed. Therefore, the fixed ring 51 will rotate on the rotating disk 52 through the ball bearing 53, and the rotating disk 52 will not rotate, thereby ensuring that the filter bag will not rotate.

[0056] It should be noted that when the extrusion plate 513 moves downward, the limit bar at its bottom collides with the swing rod 57, and when the fixed tube 44 stirs the biological bacteria, a rotational torsional force in the stirring direction is applied to the filter bag, thereby preventing the filter bag and the rotating disk 52 from rotating. If the rotating disk 52 rotates slightly due to the stirring of the fixed tube 44 inside the filter bag, the swing rod 57 rotates and is embedded between the two limit bars. The limit bar can also be used to limit the swing rod 57, so that the swing rod 57 limits the rotating disk 52 through the hinge seat 56, so that the rotating disk 52 cannot rotate, and the filter bag remains stationary.

[0057] The feeding component feeds the defoamer according to the internal air pressure of the fermentation tank 1:

[0058] During the fermentation of biological bacteria, the biological bacteria will perform respiration or other metabolic reactions during the fermentation process, thereby generating gas. The generated gas will fill the interior of the fermentation tank body 1, and bubbles will also be generated in the water. When the gas pressure inside the fermentation tank body 1 is greater than the external air pressure, the gas inside the fermentation tank body 1 will push the piston plate 68 upward from the opening 610, so that the upward movement of the piston plate 68 will compress the spring three 67. The upward movement of the piston plate 68 will push the gas originally inside the pressure relief shell 64 outward from the pressure relief hole 66. During the upward movement of the piston plate 68, the movable rod 612 will be driven to move upward inside the limit plate 611 under the action of the magnetic connection between the magnet one 69 and the magnet two 613. The movable rod 612 drives the connecting ring 614 to move upward. The connecting ring 61 4 drives the movable plug 616 to move upward inside the storage tank 615. When the movable plug 616 moves upward, it cannot fit tightly with the storage tank 615. The defoamer inside the storage tank 615 falls downward from the gap between the storage tank 615 and the movable plug 616 under the action of gravity, and then the defoamer is put into the fermentation liquid mixed with water and biological bacteria in the fermentation tank body 1. After the defoamer is mixed with water, the bubbles in the fermentation liquid can be eliminated, thereby reducing the bubbles in the fermentation liquid inside the fermentation tank body 1, thereby avoiding the generation of foam due to excessive bubbles, further avoiding the space occupied by bubbles in the fermentation tank body 1, preventing bubbles from affecting the effective volume in the fermentation tank body 1, and also preventing the problem of excessive foam overflowing from the fermentation tank body 1, thereby reducing the loss of fermentation liquid due to the overflow of foam.

[0059] Fermentation liquid discharge:

[0060] When the biological bacteria fermentation is completed, the staff will open the discharge pipe 2 to discharge the fermentation liquid outward from the discharge pipe 2. When the fermentation liquid in the fermentation tank body 1 is gradually discharged, the biological bacteria will form accumulation in the filter bag under the action of gravity, resulting in the inability to discharge the internal moisture of the accumulated biological bacteria in time, so that part of the fermentation liquid will remain in the biological bacteria in the filter bag. At this time, the staff can start the motor 42, and the motor 42 will drive the stirring shaft 43 to rotate, and the stirring shaft 43 drives the fixed pipe 44 to stir the biological bacteria, thereby breaking up the accumulated biological bacteria, and the gaps between the broken biological bacteria become larger, so that the residual fermentation liquid of the biological bacteria can effectively flow out from the gaps where the biological bacteria are broken up, thereby reducing the dripping of the fermentation liquid in the subsequent process of taking out the filter bag, reducing the waste of the fermentation liquid, and avoiding the dripping of the fermentation liquid to pollute the surrounding equipment and environment, thereby improving the utilization rate of the fermented liquid after fermentation.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
