Description

Technical Field

[0001] This utility model relates to the field of bio-organic fertilizer raw material crushing technology, and in particular to a bio-organic fertilizer raw material crushing device. Background Technology

[0002] Bio-organic fertilizer refers to a type of fertilizer that combines the effects of microbial fertilizer and organic fertilizer by harmlessly treating and composting microorganisms with specific functions and animal and plant residues. Raw materials for bio-organic fertilizer include straw, soybean meal, rapeseed cake, chicken manure, distiller's grains, vinegar residue, cassava residue, etc. Its advantages include thorough composting, high product quality, and minimal secondary pollution.

[0003] In the production of organic fertilizer, the crushing device plays a crucial role. There are various types of crushers, including hammer mills, ball mills, roller mills, and impact mills. Each type has its unique crushing principle and applicable range. For example, hammer mills, with their high efficiency and adaptability, perform exceptionally well in processing fibrous organic materials. The physical changes during the crushing process not only affect the particle size and surface area of ​​the material but can also cause an increase in material temperature. During crushing, heat is generated due to friction between the material and the internal components of the crusher, as well as plastic deformation within the material. This phenomenon is particularly pronounced in high-efficiency crushing processes. Increased temperature may lead to the loss of volatile components in the material, affecting the quality of the organic fertilizer. Existing hammer mills lack heat dissipation capabilities, potentially leading to temperature increases and the loss of volatile components, thus impacting the quality of the organic fertilizer.

An upper crushing chamber 3 is detachably mounted above the lower crushing chamber 2 via bolt assemblies. The interiors of the lower and upper crushing chambers 2 and the upper crushing chamber 3 are configured as crushing chambers. The closed crushing chambers effectively reduce dust diffusion. A rotating shaft 4 is installed inside the crushing chamber. The rotating shaft 4 is rotatably connected to the lower crushing chamber 2 via bearings. Five equally spaced mounting plates 5 are connected to the rotating shaft 4. Four mounting rods 6 are connected to the outer periphery of the mounting plates 5 near their edges. The four mounting rods 6 are evenly distributed circumferentially. Hammers 7 are connected to the mounting rods 6 and located between two mounting plates 5. The hammers 7 are made of high wear-resistant alloy steel, which can effectively resist hard impurities in organic materials and extend their service life. A drive mechanism for driving the rotating shaft 4 to rotate is installed on the frame 1. A screen 8 is also installed inside the lower crushing chamber 2. The cross-section of the crushing chamber 2 is arc-shaped, and the screen 8 is used to screen the crushed material. The bottom of the crushing chamber 2 is equipped with a discharge door, which is opened to discharge the filtered and screened material. The side wall of the crushing chamber 3 is a double-layer structure. The side wall of the crushing chamber 3 is equipped with a first cooling chamber 301. The top water inlet of the first cooling chamber 301 is connected to the cooling water source through the connecting component 14, and the bottom water outlet of the first cooling chamber 301 is connected to the drain pipe through the connecting component 14. The rotating shaft 4 is a hollow structure, and a second cooling chamber 401 is provided inside the rotating shaft 4. Cooling plates 15 are connected to both the front and rear sides of the mounting plate 5. A third cooling chamber 1501 is provided inside the cooling plate 15. The third cooling chamber 1501 is connected to the second cooling chamber 401. One end of the second cooling chamber 401 is connected to the cooling water source, and the other end of the second cooling chamber 401 is connected to the drain pipe. In actual use, a water pump can be used to deliver cooling water to increase the water pressure.

[0030] The driving mechanism includes a drive motor 10, which is mounted on the frame 1 and connected to the rotating shaft 4 via a transmission assembly. The transmission assembly includes a drive wheel 11 and a driven wheel 12. The drive wheel 11 is mounted on the output shaft of the drive motor 10, and the driven wheel 12 is mounted on the exposed end of the rotating shaft 4. The drive wheel 11 and the driven wheel 12 are connected by a transmission belt 13. In use, the drive motor 10 is started, which drives the drive wheel 11 to rotate. The rotation of the drive wheel 11 drives the driven wheel 12 to rotate via the transmission belt 13. The rotation of the driven wheel 12 drives the rotating shaft 4 to rotate, which in turn drives the mounting plate 5 and the hammer 7 to move. The hammer 7 crushes the material.

[0031] The top of the crushing upper box 3 is connected to a feeding hopper 9. The right side of the frame 1 is provided with a screw feeding mechanism 16 for feeding material into the feeding hopper 9. The screw feeding mechanism 16 adopts a screw conveyor, which is existing technology. Here, we only briefly describe its structure. Specifically, it includes a conveyor shell, inside which is a screw conveyor shaft. A conveyor motor for driving the screw conveyor shaft to rotate is installed at the bottom of the shell. The shell is arranged at an inclination. The lower feeding pipe of the shell is connected to the bottom of the storage hopper installed on the support. The discharge pipe at the top of the shell conveys the raw material to be crushed into the feeding hopper 9.

[0032] The rear side of the crushing chamber 2 is provided with a first air outlet, which is connected to the air inlet of the bag filter 18 through a pipeline. The second air outlet of the bag filter 18 is connected to the fan 17 through a pipeline.

The second connector body 1402 is provided with a plate 1404 for limiting the second connector body 1402. The insert plate 1404 has a matching slot 1405, and the insert plate 1404 has an elongated hole 1406 through which the second connector body 1402 can pass. In use, first insert the insert plate 1404 into the slot 1405, then insert the second connector body 1402 into the first connector body 1401 to complete the connection, and finally pull the insert plate 1404 upward so that the bottom of the insert plate 1404 is locked in the slot 1405 to prevent the second connector body 1402 from separating from the first connector body 1401. By setting the connecting component 14, water pipes can be quickly connected, making it more convenient to use.

[0034] The working process of this utility model is as follows:

[0035] When in use, start the drive motor 10, which drives the drive wheel 11 to rotate. The rotation of the drive wheel 11 drives the driven wheel 12 to rotate via the transmission belt 13. The rotation of the driven wheel 12 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the mounting plate 5 and the hammer 7 to move. The hammer 7 crushes the material.
