Description

Technical Field

[0001] This invention relates to an integrated equipment for continuous operation of round bamboo micro-carbonization molding, belonging to the field of bamboo heat treatment equipment. Background Technology

[0002] China has abundant bamboo resources. Bamboo plants grow quickly, are diverse in species, widely distributed, and have a wide range of uses, resulting in significant ecological, economic, and social benefits.

[0003] Currently, bamboo resources are mainly used in construction, decoration, home furnishing, water conservancy, bamboo fiber, bamboo charcoal, etc. However, due to the uneven structure of whole bamboo (round bamboo) and the obvious anisotropy of its longitudinal and transverse parts, there are unstable factors in the processing of whole bamboo (round bamboo), especially problems such as cracking and insect infestation, which has prevented the processing of round bamboo from opening up the market.

[0004] Bamboo micro-carbonization refers to placing bamboo strips in a high-temperature and high-humidity environment, which decomposes and denatures the organic matter in the bamboo, such as sugar, starch, and protein, depriving fungi and insects of their nutrient source. At the same time, it kills insect eggs and fungi attached to the bamboo. The surface hardness of the carbonized bamboo is also enhanced, and its service life is greatly extended.

[0005] Most current micro-carbonization technologies are non-continuous production processes and cannot be integrated with molding design, resulting in high system energy consumption, high production costs, and significant environmental pollution.

[0006] Invention patent CN102729303A employs steam heat treatment to dry whole bamboo. First, holes are pierced through the bamboo joints, then the bamboo is steamed with a mixture of sodium chloride and acetic acid. Next, the whole bamboo is placed in a steam tank and treated at 0.14Mpa-0.25Mpa and a temperature of 110-140℃. Finally, the whole bamboo is placed in a steam drying kiln for low-temperature drying. This process achieves drying and crack prevention of whole bamboo, improves its stability and weather resistance, increases its strength, and extends its service life.

[0007] Although steam drying can improve the strength of whole bamboo, the production process is discontinuous. In addition, the temperature of the steam used is relatively low, so the bamboo does not undergo a carbonization reaction, and its service life is still not long.

[0008] Invention patent CN112440362A discloses a highly efficient bamboo carbonization device that ensures an odor-free working environment. The device includes a sealed box with a rack fixedly connected between the inner walls of its left and right sides. Support plates are fixedly connected to both sides of the lower surface of the sealed box. A steam box is fixedly installed in the center of the lower surface of the sealed box. A steam port is opened in the center of the bottom of the inner wall of the sealed box, and the sealed box is connected to the steam box through the steam port. Electric heating devices are fixedly installed on both sides of the top of the inner wall of the steam box, with heating elements fixedly connected to the lower side of each device. A water inlet is fixedly installed on one side of the front of the outer surface of the steam box. Small heaters are fixedly installed on both sides of the top of the inner wall of the sealed box. This invention relates to the field of bamboo and wood processing technology. This highly efficient bamboo carbonization device, which ensures an odor-free working environment, is easy to use, has low operating costs, and can perfectly simulate the high temperature, high humidity, and vacuum environment required for bamboo and wood carbonization, offering strong safety. However, this patent also employs a discontinuous carbonization process and does not integrate the carbonization process with the shaping process. The micro-carbonized bamboo needs to be cooled and stored, and subsequent processing requires heating and shaping, resulting in high energy consumption and high costs. Summary of the Invention

Multiple heating tubes 22 are installed in the upper part of the micro-carbonization molding equipment shell 21. The micro-carbonization conveying device 25 and the molding conveying device 27 are respectively installed in the lower front and rear parts of the micro-carbonization molding equipment shell 21. The middle part of the outer periphery of the conveyor belt of the molding conveying device 27 is located in the middle of the... At least one row of central positioning rods 24 are arranged at intervals along the front-to-back direction, and the central positioning rods 24 are perpendicular to the surface of the conveyor belt; at least one (three on each side, a total of six) end positioning rods 23 that can move up and down synchronously are installed above the front end of the micro-carbonization conveying device 25 corresponding to the two sides of the central positioning rods 24, and the end positioning rods 23 on both sides are symmetrically arranged in an arc shape, with the top of the arc facing the rear end; at the front end and rear end of the micro-carbonization molding equipment shell 21, there are round bamboo passages that respectively connect with the round bamboo inlet at the rear end of the feeding shell 14 and the front end of the continuous cooling discharge device 3.

[0024] The positioning rods 23 at both ends can be driven by a pneumatic (hydraulic) cylinder or a motor through a transmission mechanism, which is a conventional technology.

[0025] An overlap plate 5 is provided between the front end of the micro-carbonization conveyor 25 and the rear end of the baffle conveyor belt 11 of the drying feed device 1 (see...). Figure 1 ), used to convey the round bamboo 4-baffle conveyor belt 11 to the micro-carbonization conveyor device 25.

[0026] The micro-carbonization conveying device 25 adopts a conventional chain conveyor or other conveying device with the same function.

Most of the discharge conveyor belt 33 is installed inside the housing 32, and the rear end of the discharge conveyor belt 33 extends out of the rear end outlet of the housing 32. Cooling air outlet 31 and cooling air inlet 36 are respectively provided at the top of the front part and the bottom of the rear part of the housing 32.

[0028] The working process of the integrated equipment for continuous micro-carbonization molding of round bamboo of the present invention includes:

[0029] See Figure 1 and Figure 2Round bamboo 4, cut into lengths of 1.5m-4.0m, is placed between the baffles at the front end of the baffle conveyor belt 11 of the baffle-type drying feeding device 1 (the left side in the figure is the front end, and the right side is the rear end). As the baffle conveyor belt 11 conveys the bamboo backward, it passes through the sealed curtain 12 at the front end and enters the feeding shell 14. By controlling the speed of the baffle conveyor belt 11, the round bamboo 4 stays in the baffle-type drying feeding device for 0.5-2.5 hours. Hot air enters the feeding shell 14 from the hot air inlet 16 to dry the round bamboo 4 on the baffle conveyor belt 11. The dried hot air is discharged from the drying outlet 13.

[0030] After drying, the round bamboo 4 is fed into the integrated micro-carbonization molding equipment 2 through the sealed curtain 12 at the rear end of the feeding shell 14. First, it enters the front micro-carbonization conveying device 25. The heating pipe 22 above the micro-carbonization conveying device 25 can use electricity or gas as a heating source. The shape of the heating pipe 22 can be circular, inverted triangle, or square. After the round bamboo 4 is micro-carbonized by the heat from the heating pipe 22, it is fed into the molding conveying device 27 for molding. The molding conveying device 27 uses a chain conveyor or gear conveyor. The central positioning rod 24 on the molding conveying device 27 is used to fix the center position of the round bamboo. The two end positioning rods 23 move downwards to the right side of both ends of the round bamboo 4, blocking both ends of the round bamboo (see...). Figure 2 The middle part of the round bamboo 4 moves backward (right side in the figure) under the push of the middle positioning rod 24, so that the round bamboo 4 bends into an arc shape. When the round bamboo 4 bends into the required shape, the forming conveyor device 27 stops running for a period of time to fix the shape. After the shape is fixed, the positioning rods 23 at both ends move upward to reset, and the forming conveyor device 27 continues to move backward by the distance of the adjacent round bamboo 4. Then the above process is repeated until all the round bamboo 4 are formed.

[0031] After being shaped, the round bamboo 4 is removed from the outlet at the rear end of the shell 21 of the micro-carbonization molding equipment and enters the continuous cooling discharge device 3 through the discharge sealing curtain 34 for cooling. The cooled round bamboo 4 is continuously output from the discharge sealing curtain 34 at the rear end of the shell 32. The discharge conveyor belt 33 of the continuous cooling discharge device 3 adopts a multi-hole structure and is arranged horizontally to send the shaped round bamboo 4 out of the conveyor outlet of the integrated carbonization molding equipment 2. The discharge sealing curtain 34 uses multiple layers of curtain cloth to seal the shell 32. The cooling gas enters the discharge conveyor belt 33 through the cooling air inlet 36, and after passing through the multi-hole of the discharge conveyor belt 33, it comes into contact with the round bamboo 4 for cooling. The gas after heat exchange is discharged from the cooling air outlet 31, and the cooled shaped round bamboo is output from the rear end of the discharge conveyor belt 33.
