Description

Technical Field

[0001] This utility model relates to the field of carbonization equipment technology, specifically to a charcoal making equipment. Background Technology

[0002] my country is a major charcoal producer, with an annual output of tens of millions of tons. With the rapid development of the national economy, the demand for charcoal is also increasing year by year. At the same time, my country is also a major agricultural producer, generating approximately 7 billion tons of biomass waste annually, including crop straw, miscellaneous trees, and other timber. Apart from a small portion used as animal feed, fuel, and industrial fuel, the majority is directly burned or discarded in the fields, causing serious environmental pollution. The utilization rate is only 20%, resulting in a significant waste of natural resources. Biomass carbonization technology can effectively convert this biomass waste into biomass carbonization products—combustible gas and biochar (biochar is charcoal). This significantly reduces the demand for natural wood, effectively protecting forestry resources, while also effectively utilizing biomass waste. Biochar has a wide range of uses. It can be used for domestic purposes such as grilling and heating, and can also be combined with agriculture and forestry as a soil conditioner to improve soil and promote better plant growth. Furthermore, biochar can be further processed into activated carbon for air and water purification.

[0003] A carbonization machine is a device for carbonizing objects. However, existing carbonization machines are simple in design and cannot meet people's growing needs. In the traditional biochar preparation process, most steps require manual handling and transfer to the next step, resulting in slow carbonization speed and wasted manpower and resources. Furthermore, issues such as the fineness of raw materials, the uniformity of heat drying, the influence of humidity, and the control of molding conditions lead to unstable product quality.

The crusher 1, conveying and drying mechanism 2, mixing chamber 3, carbonization mechanism 4, and forming mechanism 5 are all communicatively connected to the controller. Specifically, the feed end of the conveying and drying mechanism 2 corresponds to and is located below the discharge port of the crusher 1; the feed end of the mixing chamber 3 corresponds to and is located below the discharge end of the conveying and drying mechanism 2; the feed end of the carbonization mechanism 4 is connected to the discharge port of the mixing chamber 3; and the feed end of the forming mechanism 5 corresponds to and is located below the discharge end of the carbonization mechanism 4. By integrating crushing, drying, mixing, carbonization, conveying, and forming functions into one unit, the production process is simplified, the footprint of the charcoal-making equipment is reduced, and the intensity of manual operation and production costs are lowered.

The top of the drying chamber 24 is respectively provided with an air inlet pipe 25 and an air outlet pipe 26. The feed end of the conveyor belt group 22 is located below the discharge port of the crusher 1. The end of the conveyor belt group 22 closer to the crusher 1 is the feed end of the conveyor belt group 22, and the opposite end is the discharge end. The drying chamber 24 provides a hot air space for drying the pulverized material on the conveyor belt. The drying chamber 24 is connected to the hot air outlet of an external hot air furnace via an air inlet pipe 25, and to the outside via an air outlet pipe 26. The inner wall of the drying chamber 24 can also be equipped with a temperature sensor and a photoelectric sensor electrically connected to the controller. The photoelectric sensor detects the thickness of the material on the conveyor belt of the conveyor belt assembly 22, and the temperature sensor detects the temperature inside the drying chamber 24. These measured values ​​are fed back to the controller, which controls the rotation speed of the conveyor motor 23, thereby adjusting the speed of the conveyor belt. When the conveyor motor 23 starts, it drives the conveyor belt assembly 22 to rotate, transporting the pulverized material from the discharge port of the pulverizer 1 to the drying chamber 24 for drying. After drying, the material is then transported to the mixing chamber 3.

The mixing cylinder 32 has two inner walls on both sides, and the two ends of the screw rod 36 extend through and out of the mixing cylinder 32. A mixing motor 37 is disposed on the outer wall of the mixing cylinder 32 and is communicatively connected to the controller. The output shaft of the mixing motor 37 is connected to a drive wheel. A driven wheel is disposed on the outer wall of one end of the screw rod 36. The driven wheel is located outside the mixing cylinder 32. The drive wheel is connected to the driven wheel via a belt. A guide trough 38 is inclinedly disposed on the top side of the feeding section 33, corresponding to the bottom of the discharge end of the conveyor belt assembly 22. The guide trough 38 is used to collect the dried material from the discharge end of the conveyor belt assembly 22. In this embodiment, the mixing cylinder 32 is inclined, with its lower end close to the discharge end of the conveyor belt assembly 22 and its upper end close to the feeding end of the carbonization mechanism 4. Furthermore, both the feeding section 33 and the storage box 35 are located at the lower end of the mixing cylinder 32.

[0030] like Figure 5 As shown, the carbonization mechanism 4 includes a third support 41, a carbonization furnace 42 mounted on top of the third support 41, the carbonization furnace 42 being an existing carbonization furnace used for carbonizing materials such as straw, and an inert gas protection box 43 mounted on the outer wall of the carbonization furnace 42 and communicating with its interior. The inert gas protection box 43 is existing technology, and its specific structure will not be described in detail here. Both the carbonization furnace 42 and the inert gas protection box 43 are communicatively connected to a controller. The top side wall of the carbonization furnace 42 is provided with a first pipe communicating with the discharge section 34, and the bottom side wall of the carbonization furnace 42 is provided with a second pipe corresponding to the feed end of the forming mechanism 5.

[0032] When using the charcoal-making equipment of this utility model, straw and other materials are placed into the feed hopper 13 of the crusher 1. By starting the crushing motor, the crushing motor drives the rotating shaft 15 to rotate, thereby crushing the straw through the cutting gear set. The crushed material falls from the discharge hopper 14 onto the feed end of the conveyor belt set 22. The conveyor belt set 22 further transports the crushed material to the drying chamber 24. After the material in the drying chamber 24 is dried, it is transported to the feeding section 33 by the conveyor belt set 22. The feeding section 33 transports the dried material to the mixing drum 32. At this time, the controller activates the control valve on the fixed pipe and connects the storage box 35 and the mixing drum 32. The material (iron-carbon alloy powder) stored in the storage bin 35 is transported to the mixing cylinder 32. Then, a binder is added to the mixing cylinder 32 through the feeding part 33. The mixing motor 37 is started to rotate in both directions, and the material in the mixing cylinder 32 is fully stirred by the screw rod 36. After stirring, the control valve on the first pipe of the carbonization mechanism 4 is started, so that the mixed material enters the carbonization furnace 42 for high-temperature carbonization. After carbonization, the control valve on the second pipe is started, and the carbonized material is transported to the molding machine 51 through the forming feed funnel 53 and the connecting pipe 52, so that the carbonized material can be quickly extruded into granules, blocks, etc.
