Description

Technical Field

[0001] The present invention relates to the technical field of bio-enzyme production, and in particular to a system for producing enzyme fertilizer from perishable agricultural waste and a production method thereof. Background Art

[0002] The main purpose of bio-enzyme fermentation is to break down large molecules into small molecules, making them easier to absorb and utilize. Specifically, through the fermentation of microorganisms, large molecular proteins, polysaccharides and other components in raw materials such as plants and fungi are broken down into small molecular amino acids and monosaccharides.

[0003] In order to utilize discarded agricultural products, factories or individuals usually collect discarded agricultural products (such as rotten or spoiled fruits, vegetables and crops, etc.) and process the collected agricultural products into pulp, which can transform the discarded agricultural products into useful resources, thereby reducing the burden on the environment.

[0004] However, in the process of pulping agricultural products, it is necessary to introduce bio-enzyme fermentation technology to optimize the quality of the pulp. Through fermentation treatment, the undesirable components in the pulp can be removed and the value of the pulp can be improved. At the same time, bio-enzyme fermentation can also enhance the stability of the pulp and extend its shelf life.

[0005] At present, when pulping discarded agricultural products (such as vegetables, fruits and crops), it is first necessary to use tools to cut the larger agricultural products into several pieces, and then dump the cut agricultural products into a fermentation box for fermentation. However, since the sizes of crops cut manually vary, when the size of crops varies greatly, the water absorption and cooking degree will be inconsistent, which will affect the degree of protein denaturation and the utilization rate of raw materials. This means that some waste materials may not be effectively utilized by microorganisms due to insufficient cooking, thereby reducing the fermentation efficiency. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1 See also Figure 1-7 ,include: A fermentation box 8 is provided with a crushing box 1 on the outside. A crushing piece for crushing agricultural products is provided in the inner cavity of the crushing box 1. Before the discarded agricultural products (such as spoiled fruits, vegetables and crops) are fermented, the discarded agricultural products are poured into the crushing piece. Different types of agricultural products are quickly crushed by the crushing piece. The crushed agricultural products fall into the crushing box 1 under the action of their own gravity and the crushing piece. The crushed agricultural products are mixed with the water in the crushing box 1 until the crushed agricultural products and the water are completely mixed. The crushed agricultural products and the water are poured into the fermentation box 8. The fermentation box 8 heats the internal water, thereby increasing the activity of the microorganisms in the fermentation box 8 and improving the efficiency of agricultural product fermentation.

[0023] The crushing part includes a hydraulic cylinder 7 and a moving ring 4. The moving ring 4 is slidably installed just above the crushing box 1. The hydraulic cylinder 7 is symmetrically fixedly installed on the outer wall of the crushing box 1. The power output end of the hydraulic cylinder 7 is fixedly installed with a support plate 2. The end of the support plate 2 away from the hydraulic cylinder 7 is fixedly connected to the outer wall of the moving ring 4. By starting the two hydraulic cylinders 7 at the same time, the synchronous movement of the moving ring 4 can be achieved, and the tilting of the moving ring 4 when moving up and down can be prevented, which can improve the stability of the moving ring 4 moving up and down.

[0024] A crushing tube 5 is detachably installed in the inner cavity of the movable ring 4, a crushing roller 19 is rotatably installed in the inner cavity of the crushing tube 5, a spiral blade for crushing agricultural products is fixedly installed on the outer wall of the crushing roller 19, and a feeding pipe 6 connected to its own inner cavity is fixedly installed on the outer wall of the crushing tube 5, through which the discarded agricultural products can be dumped into the inner cavity of the crushing tube 5.

[0025] A transmission motor for rotating the crushing roller 19 is fixedly installed on the top of the crushing tube 5. The power output end of the transmission motor extends to the inside of the crushing tube 5 and is fixedly connected to the top of the crushing roller 19. Before pouring the waste agricultural products into the inner cavity of the crushing tube 5 through the feeding tube 6, the transmission motor is started to rotate the crushing roller 19. At this time, the spiral blade rotates rapidly with the crushing roller 19, thereby quickly crushing the waste agricultural products entering the crushing tube 5.

[0026] When the spiral blade rotates, it can not only quickly crush the discarded agricultural products, but also there is a certain gap between the spiral blade and the inner cavity of the crushing tube 5. The spiral blade and the inner wall of the crushing tube 5 provide a moving channel for the movement of agricultural products. Under the action of the spiral blade, the crushed agricultural products fall into the inner cavity of the crushing box 1 through the moving channel.

[0027] The crushing parts also include a cutting pump 15 and a cutting blade 16. The cutting pump 15 is detachably installed in the inner cavity of the crushing box 1. The cutting blade 16 is fixedly installed at the power output end of the cutting pump 15. The cutting pump 15 is composed of a water pump. In order to speed up the extraction and transmission of water and prevent debris from being blocked at the water inlet end during pumping, a power output shaft is installed at the water inlet end of the water pump. The outside of the power output shaft is installed with a cutting blade 16, so as to quickly break the blockage at the water inlet end.

[0028] A material blocking box 14 is fixedly installed on the top of the cutting pump 15, and the power output end of the cutting pump 15 extends into the inner cavity of the material blocking box 14. A mesh tube 13 is detachably installed on the bottom of the crushing tube 5 through threaded matching. The diameter of the mesh tube 13 is the same as that of the material blocking box 14. Before starting the transmission motor, first start the two hydraulic cylinders 7 to let the moving ring 4 move down with the power output end of the hydraulic cylinder 7 until the bottom of the mesh tube 13 fits with the top of the material blocking box 14. After the initial cutting by the spiral blade, the discarded agricultural products pass through the mesh tube 13 and fall into the material blocking box 1 4, and then start the cutting pump 15. At this time, the cutting blade 16 rotates rapidly with the power output end of the cutting pump 15, so as to crush the waste agricultural products after the preliminary cutting again. While the cutting pump 15 crushes the waste agricultural products through the cutting blade 16, it can also suck the crushed agricultural products through its own water inlet end and discharge them from the water outlet end, so that the agricultural products that have been crushed for the second time in the blocking box 14 can be quickly discharged into the crushing box 1, so as to prevent a large amount of agricultural products from accumulating in the blocking box 14 and affecting the secondary cutting of the agricultural products by the cutting blade 16.

[0029] When the cutting pump 15 sucks in the agricultural products after secondary crushing and discharges them through the water outlet, the water inside the crushing box 1 quickly enters the interior of the material blocking box 14 through the mesh tube 13, thereby quickly mixing with the crushed agricultural products inside the material blocking box 14, diluting the crushed agricultural products, and improving the efficiency of the cutting pump 15 in quickly sucking in and discharging the secondary crushed agricultural products into the crushing box 1.

[0030] When the agricultural products inside the retaining box 14 come into contact with the cutting blade 16, the agricultural products are impacted by the cutting blade 16 and move away from the cutting blade 16 until the agricultural products collide with the inner wall of the retaining box 14, and the moving position of the agricultural products is limited. Then, the agricultural products collide with the cutting blade 16 again along with the water flow. In this reciprocating manner, the agricultural products can be repeatedly crushed until the size of the crushed agricultural products can be sucked into the cutting pump 15 along with the water flow and discharged into the inner cavity of the crushing box 1.

[0031] After the discarded agricultural products are completely crushed, the two hydraulic cylinders 7 are started at the same time until the power output ends of the two hydraulic cylinders 7 move up to the maximum value. The water inside the crushing box 1 flows in the horizontal direction under the stirring of the cutting blade 16, so that the water and the crushed agricultural products are quickly and evenly mixed, and then the mixed water and agricultural products are poured into the fermentation box 8 for static fermentation. The agricultural products are crushed into suspended particles by the cutting blade 16, so that the water absorption and cooking degree of the crushed agricultural products are almost the same, which improves the degree of protein denaturation and the utilization rate of raw materials, so that different types of agricultural products can be used by microorganisms, and the efficiency of agricultural product fermentation is improved.

[0032] The mounting hole is opened at the bottom of the crushing box 1. A conduit 12 is arranged outside the crushing box 1. One end of the conduit 12 is fixedly connected to the inner wall of the mounting hole. A water pump 9 is fixedly installed on the outer wall of the fermentation box 8. The other end of the conduit 12 is fixedly connected to the water inlet end of the water pump 9. A water pipe is fixedly installed at the water outlet end of the water pump 9. The other end of the water pipe is fixedly connected to the top of the crushing box 1. After the water inside the crushing box 1 and the crushed agricultural products are evenly mixed, the water pump 9 is started. At this time, the crushed agricultural products inside the crushing box 1 are sucked into the conduit 12 together with the water, and then enter the fermentation box 8 through the conduit 12, the water pump 9 and the water pipe, so that the crushed agricultural products can be left to ferment.

[0033] One end of the discharge pipe 10 is fixedly connected to the bottom of the fermentation box 8, and a valve for controlling the flow rate of the slurry is rotatably installed in the inner cavity of the discharge pipe 10. When the agricultural products are fermented inside the fermentation box 8, the valve is rotated. At this time, the slurry inside the fermentation box 8 is discharged to the outside of the fermentation box 8 through the discharge pipe 10 under the action of gravity, thereby realizing the collection of the slurry.

[0034] According to the above embodiment, when agricultural products are left to ferment in the fermentation box 8, microorganisms will consume oxygen and produce waste gases such as carbon dioxide. These waste gases need to be discharged from the fermentation box 8 in time to maintain the gas balance and pressure stability in the fermentation box 8. If the waste gases accumulate in a sealed environment, they will cause pressure on the fermentation box 8, which may even cause explosion danger over time. In order to solve the above problem, this embodiment also includes a through hole, which is opened at the top edge of the crushing box 1. An exhaust pipe 11 is fixedly installed in the inner cavity of the through hole, and a one-way valve for exhaust is slidably installed in the inner cavity of the exhaust pipe 11. When the air pressure in the fermentation box 8 is greater than the external air pressure, a thrust is applied to the one-way valve in the exhaust pipe 11. At this time, the one-way valve is in an open state, and the waste gas such as carbon dioxide in the fermentation box 8 is discharged through the exhaust pipe 11, so as to prevent the tank body from exploding due to the high air pressure inside the fermentation box 8.

[0035] Until the air pressure inside the fermentation box 8 is the same as or lower than the external air pressure, the one-way valve is in a closed state, isolating the fermentation box 8 from the external air, which can accelerate the activity of the microorganisms in the fermentation box 8.

[0036] A driving motor is fixedly installed in the inner cavity of the conduit 12, and a spoiler 18 for accelerating the outflow of slurry is fixedly installed at the power output end of the driving motor. The spoiler 18 is located directly above the mounting hole. When the water pump 9 is started, the driving motor is started at the same time to allow the spoiler 18 to rotate rapidly, thereby accelerating the flow rate of the water directly above the mounting hole, allowing the water and the crushed agricultural products to flow quickly into the fermentation box 8.

[0037] A mounting plate is provided directly above the mounting hole, and a plurality of material blocking rods 17 are fixedly installed on the outer wall of the mounting plate in a circular shape. The end of the material blocking rod 17 away from the mounting plate is fixedly connected to the bottom of the inner cavity of the crushing box 1. The plurality of material blocking rods 17 will wrap the top of the mounting hole to prevent some uncrushed agricultural products from falling directly above the mounting hole and blocking the conduit 12.

[0038] The bottom of the movable ring 4 is fixedly installed with a plurality of U-shaped clamps 3 in a circular shape to increase its own stability. When the bottom of the mesh tube 13 and the top of the material blocking box 14 are fitted together, the opening end of the crushing box 1 and the inner walls of the plurality of U-shaped clamps 3 are fitted together, thereby limiting the movable ring 4 to prevent the movable ring 4 from vibrating when the crushing roller 19 rotates and causing the bottom of the mesh tube 13 and the top of the material blocking box 14 to shift, causing the agricultural products after the initial crushing inside the crushing tube 5 to be directly mixed with the water inside the crushing box 1.

[0039] The inner wall of the moving ring 4 is fixedly installed with multiple connecting plates distributed in an annular shape, and one end of the multiple connecting plates away from the inner wall of the moving ring 4 is connected to the outer wall of the crushing tube 5 by threaded cooperation. The connection between the crushing tube 5 and the moving ring 4 can be achieved through the multiple connecting plates distributed in an annular shape, and the crushing tube 5 and the moving ring 4 can be separated by threaded cooperation, so as to facilitate the removal of the cutting pump 15 from the inside of the crushing box 1, which is beneficial to the replacement and maintenance of the cutting pump 15.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
