Description

Technical Field

[0001] The present invention relates to the technical field of ecological environment material equipment, and in particular to an ecological environment material crushing and degradation device and a degradation treatment method. Background Art

[0002] Eco-environmental materials generally refer to functional materials with excellent environmental coordination, and have the characteristics of renewability, low carbon emissions, recycling, degradability, health and environmental protection. Eco-environmental materials can decompose and degrade under natural conditions and will not cause long-term pollution to the environment. However, the degradation rate under natural conditions is slow, so a series of technical development and management measures are needed to improve efficiency, which will also help to further promote the application of eco-environmental materials. Common eco-environmental materials include biopolymer-based degradable materials, green building materials, natural materials, environmentally friendly recycled materials, etc.

[0003] In the prior art, a variety of degradation and differentiation devices for ecological and environmental materials have been developed, such as Chinese patent documents with publication numbers CN115646990A, CN116213424A, and CN113136318A. Due to the viscosity of the ecological and environmental materials themselves, it is easy for the materials to stick to the inner wall during the processing. In order to solve this technical problem, the patent document CN115646990A installs a knocking piece to repeatedly knock the body, so that the material will not stick to the inner wall of the degradation and differentiation device, avoiding the need for manual cleaning of the material after the degradation operation; the patent document CN116213424A uses the support rod, support plate, spring and vibration motor to make the device have the advantage of anti-adhesion function, and can vibrate the box body during discharge, so that the material will not stick to the inner wall of the box body, thereby improving its discharge effect. In addition, the material blown away by the crushing blade will also be retained on the inner wall of the body, which will not only affect the crushing effect, but also have a certain impact on the subsequent cleaning of the body.

[0004] Degradation methods are also key to the degradation of ecological and environmental materials, including biodegradation, chemical degradation and photocatalytic degradation. The biodegradation method does not produce secondary pollution, is environmentally friendly, and degrades ecological and environmental materials thoroughly, but has the disadvantages of long degradation time and low efficiency; the chemical degradation method usually needs to be carried out under specific environmental conditions (temperature, pressure, etc.), but some chemical reagents used in the chemical degradation process may cause secondary pollution to the environment and the removal of new products; photocatalytic degradation has good controllability, but there is a problem of difficult degradation under insufficient sunlight or non-light conditions.

[0005] Therefore, in order to solve the problems related to the degradation of ecological environmental materials, it is necessary to develop an ecological environmental material crushing and degradation device and a corresponding degradation treatment method. Summary of the invention

The crushing assembly includes a first blade 11 and a second blade 12. The first blade 11 and the second blade 12 are connected to the rotating shaft 3. The first blade 11 includes a plurality of cutting surfaces and a fixed surface. The plurality of cutting surfaces and the fixed surfaces form a protrusion toward the crushing barrel 9. The fixed surface of the first blade 11 contacts the top of the second screen 10; the second blade 12 is arranged on the upper part of the first blade 11, and the length of the second blade 12 is greater than that of the first blade 11.

[0043] The bottom plate 1 is used as the supporting base of the whole device and is made of a strong and durable metal material to ensure the stability of the device. The degradation barrel 2 is fixedly connected to the bottom plate 1 and is made of corrosion-resistant and wear-resistant materials, such as stainless steel or polymer composite materials. The degradation barrel 2 is designed to be cylindrical, with an opening at the top for easy installation of a crushing assembly, and a first screen 8 is provided at the bottom.

[0044] The first blade 11 is directly fixedly connected to the rotating shaft 3, and its position ensures close contact with the top of the second screen 10. As the rotating shaft 3 rotates, the first blade 11 not only cuts the passing ecological and environmental materials, but also helps push the materials toward the screen through its contact with the second screen 10, thereby achieving preliminary filtration and refinement. This design not only enhances the cutting effect, but also promotes further separation of the materials. Each second blade 12 is also fixedly connected to the rotating shaft 3, but their position is located on the upper part of the first blade 11. Such a layout enables the blade assembly to form a multi-level cutting effect when rotating, thereby ensuring the uniformity and thoroughness of the cutting.

[0045] The outer walls of the degradation barrel 2 and the crushing barrel 9 are provided with an oscillation component, which produces an oscillation effect on the crushing barrel. The mounting blocks 13 in the oscillation component are respectively fixedly connected to the two sides of the degradation barrel 2, and the second motors 14 are respectively installed on the corresponding mounting blocks 13. The rotating plate 15 is connected to the output shaft of the second motor 14 through a key. The oscillation blocks 16 are respectively fixedly connected to the two sides of the crushing barrel 9, and the first oscillation plates 17 are respectively fixedly connected to the corresponding oscillation blocks 16.

The tension rods 20 are respectively fixedly connected to the corresponding second oscillation plates 19, and the tension rods 20 are in contact with one end of the rotating plate 15.

[0046] The oscillation component enhances the mixing and refining effect of the internal material by oscillating the crushing barrel 9. Each mounting block 13 is firmly fixedly connected to the two sides of the degradation barrel 2 to provide a stable foundation for the installation of the oscillation component. These mounting blocks 13 are usually made of corrosion-resistant and high-strength materials to ensure stability and reliability in long-term use. A corresponding second motor 14 is installed on each mounting block 13 as the power source of the oscillation component. The rotating plate 15 is fixed to the output shaft of the second motor 14 by a key connection and rotates synchronously with the rotation of the second motor 14. The design of the rotating plate 15 takes into account the coordination with the tension rod 20. Each oscillation block 16 is fixedly connected to the two sides of the crushing barrel 9 to form a corresponding layout with the mounting block 13 and the rotating plate 15. The oscillation block 16 serves as a bridge connecting the crushing barrel 9 and the oscillation component, and bears the force generated during the oscillation process. Each first oscillation plate 17 is fixedly connected to the crushing barrel 9. The first vibration plate 17 is fixedly connected to the corresponding vibration block 16. The design of the first vibration plate 17 takes into account the connection method with the elastic rope 18 to ensure that the force can be stably transmitted when subjected to tension. Each elastic rope 18 is fixedly connected to the first vibration plate 17, and the other end is connected to the second vibration plate 19.

The design of the second vibration plate 19 takes into account the cooperation with the rotating plate 15. When the rotating plate 15 rotates to release the contact with the tension rod 20, the force is transmitted to the second vibration plate 19 through the tension rod 20, and then transmitted to the crushing barrel 9 through the elastic rope 18 and the first vibration plate 17, thereby producing a vibration effect.

[0047] Secondly, in this embodiment, the cover plate 21 is fixedly connected to the top of the crushing barrel 9, and the rotating shaft 3 passes through the cover plate 21 and is rotatably connected to the cover plate 21, the first motor 22 is installed on the top of the cover plate 21, and the output end of the first motor 22 is connected to the top of the rotating shaft 3 by a key, and each support rod 23 is fixedly connected to the four sides of the base plate 1 respectively.

[0048] Finally, in this embodiment, each supporting plate 24 is fixedly connected to both sides of the outer wall of the degradation barrel 2, each containing box 25 is fixedly connected to the top of the corresponding supporting plate 24, and the containing box 25 is fixedly connected to the outer wall of the degradation barrel 2, each through hole (degradation liquid inlet) is respectively opened on the inner wall of the corresponding containing box 25, and each through hole passes through the degradation barrel 2, each delivery pipe 26 is fixedly connected to the inner wall of the corresponding through hole containing box 25 side, and each blocking block 27 is respectively connected to the top of the containing box 25 by threading.

[0049] Each supporting plate 24 is firmly fixedly connected to both sides of the degradation barrel 2. These supporting plates 24 provide a stable supporting platform for the containing box 25, ensuring that the containing box 25 can remain stable during the degradation and differentiation process, and will not shift or tilt due to the impact or vibration of the material. Each containing box 25 is fixedly connected to the top of the corresponding supporting plate 24, and the containing box 25 is also fixedly connected to the outer wall of the degradation barrel 2. This double fixing method ensures the stability and safety of the containing box 25 during the degradation and differentiation process. The design of the delivery pipe 26 can ensure that the degradation liquid can enter the containing box 25 along a specific path when passing through the through hole, reducing the loss and contamination of the degradation liquid during the transmission process. The material of the delivery pipe 26 should have good corrosion resistance and wear resistance to ensure stability and reliability for long-term use. Each blocking block 27 is respectively connected to the top of the containing box 25 by a thread. The design of the blocking block 27 allows the user to open or close the opening on the top of the containing box 25 at any time as needed to fill the degradation liquid into the containing box 25.

[0050] When the ecological environment material crushing and degradation device is working, the ecological environment material to be processed (plant meal, straw or biodegradable film) is first crushed to facilitate subsequent degradation, and the ecological environment material to be processed is transported to the crushing barrel 9 through the discharge port, and then the first motor 22 is started, and the first motor 22 is started to drive the rotating shaft 3 to rotate, and the rotation of the rotating shaft 3 drives the first blade 11 and the second blade 12 to rotate, and the material transported into the crushing barrel 9 is crushed, and the second motor 14 is started at the same time, and the second motor 14 is started to drive the rotating plate 15 to rotate, and the rotating plate 1 The rotation drives the tension rod 20 to move, and the movement of the tension rod 20 drives the second oscillation plate 19 to move, and the movement of the second oscillation plate 19 drives the elastic rope 18 to stretch. When the rotating plate 15 pushes the tension rod 20 to a high place, the rotating plate 15 is released from the tension rod 20, and the elastic rope 18 contracts to drive the second oscillation plate 19 to knock on the first oscillation plate 17, and cooperate with the oscillation block 16 to knock and oscillate the crushing barrel 9, so as to shake the materials attached to the inner wall of the crushing barrel 9 down, which not only increases the crushing efficiency, but also provides convenience for the subsequent cleaning of the crushing barrel 9.

[0051] Qualified materials will pass through the second screen 10 and be transported to the degradation barrel 2. Unqualified materials will be crushed by the contact between the first blade 11 and the second screen 10 to further process them. When the materials enter the degradation barrel 2, the degradation liquid in the holding box 25 (the mass ratio of lipase, protease, cellulase and amylase is 4:1:1:2) is transported to the degradation barrel 2 through the delivery pipe 26 to react with the materials. At the same time, the rotation of the rotating shaft 3 drives the first stirring rod 4 to rotate, the rotation of the first stirring rod 4 drives the connecting rod 6 to rotate, and the rotation of the connecting rod 6 drives the second stirring rod 5 and the auxiliary rod 7 to rotate, so as to stir the materials in the degradation barrel 2 so that the materials and the degradation liquid are fully fused and reacted. The degraded materials are transported out through the first screen 8. At the same time, the first stirring rod 4 contacts the first screen 8. When the first stirring rod 4 rotates, the materials attached to the first screen 8 are taken out and crushed, which not only improves the efficiency of material degradation, but also saves the workload of workers, improves the work efficiency of workers, and realizes the efficient degradation of the ecological environment materials to be treated.
