DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A biomass gas tank for wood waste in this embodiment includes a base 1, a combustion chamber 2 is arranged on the top of the base 1, a crushing chamber 3 is arranged on the top of the combustion chamber 2, a shell 4 is arranged on the left side of the combustion chamber 2, a power mechanism 5 is arranged inside the shell 4, a crushing mechanism 6 is arranged inside the crushing chamber 3, and a uniform feeding mechanism 7 is arranged inside the combustion chamber 2.

[0024] The crushing mechanism 6 includes a second gear 601, which is rotatably mounted inside the housing 4. A connecting rod 602 rotatably connected to the right inner wall of the crushing chamber 3 is fixedly mounted on the right end of the second gear 601, and a crushing blade 603 is fixedly mounted on the outer surface of the connecting rod 602.

[0025] A feed port is provided at the top of the crushing chamber 3, and a discharge port extending to the interior of the combustion chamber 2 is provided at the bottom of the crushing chamber 3. Wood waste is put into the crushing chamber 3 from the feed port, and then enters the combustion chamber 2 from the discharge port after being crushed; the particle size of the crushed wood waste is reduced and the relative surface area is increased, which makes their contact with oxygen more sufficient, thereby improving the combustion efficiency. Compared with large pieces of uncrushed wood, small pieces of waste can be heated faster and reach the ignition point during combustion; due to the increase in contact area, the speed at which heat is released from the wood waste is also increased accordingly, which helps to shorten the overall combustion time and make energy conversion faster and more efficient.

[0026] The uniform speed feeding mechanism 7 includes a slide plate 701, on which the slide plate 701 is slidably mounted, and a push rod 702 is fixedly mounted on the right side of the slide plate 701. The outer surface of the push rod 702 is sleeved with a spring 703 fixedly mounted between the right side of the slide plate 701 and the right inner wall of the shell 4, and a baffle 704 is fixedly mounted on the right end of the push rod 702.

[0027] A feeding port located at the top of the baffle 704 is provided at the bottom of the crushing chamber 3 , a through opening 706 matching the feeding port is provided on the baffle 704 , and a guide rod 705 slidably connected to the inner top wall of the combustion chamber 2 is fixedly installed on the right side of the baffle 704 .

[0028] By moving the baffle 704 left and right, the opening 706 is driven to overlap with the feed opening intermittently, so that the crushed wood waste in the crushing chamber 3 can evenly enter the interior of the combustion chamber 2. This uniformity helps to form a more uniform combustion environment in the combustion chamber 2, avoiding local overheating or incomplete combustion caused by uneven feeding. The evenly distributed material helps to optimize the heat transfer process, so that heat can be more effectively released from the wood waste, thereby improving the overall combustion efficiency. Since the combustion is more complete, the energy loss caused by uneven feeding is reduced, thereby reducing the overall fuel consumption.

[0029] The power mechanism 5 includes a motor 501, which is fixedly mounted on the rear inner wall of the shell 4, and a rotating rod 1 502 is fixedly mounted on the output shaft of the motor 501 and rotatably mounted on the front inner wall of the shell 4, and a rotating rod 2 504 is rotatably mounted between the front and rear inner walls of the shell 4.

[0030] A pulley 503 is fixedly mounted on the outer surface of the rotating rod 1 502 , a pulley 505 is fixedly mounted on the outer surface of the rotating rod 2 504 , and a mounting belt 507 is transmission-connected between the outer surfaces of the pulley 1 503 and the pulley 2 505 .

[0031] Under the joint action of the pulley 1 503, the pulley 2 505 and the mounting belt 507, when the motor 501 is turned on, it can drive the rotating rod 1 502 and the rotating rod 2 504 to rotate simultaneously, so that the crushing mechanism 6 and the uniform speed feeding mechanism 7 operate simultaneously.

[0032] A cam 508 in contact with the slide plate 701 is fixedly mounted on the outer surface of the rotating rod 1 502 , and a gear 1 506 meshing with the gear 2 601 is fixedly mounted on the outer surface of the rotating rod 2 504 .

[0033] The rotation of the cam 508 drives the slide plate 701 to slide back and forth left and right, thereby causing the baffle 704 to move back and forth left and right; the engagement of the gear 1 506 and the gear 2 601 can drive the connecting rod 602 to rotate.

[0034] A guide rod 705 slidably connected to the inner top wall of the combustion chamber 2 is fixedly installed on the right side of the baffle 704. The guide rod 705 is provided to improve the stability of the baffle 704 when it moves left and right.

[0035] A fan is fixedly installed on the top of the base 1, an air inlet pipe is fixedly installed between the fan and the combustion chamber 2, and an air outlet pipe is fixedly installed on the left side of the combustion chamber 2. The air inlet pipe guides the airflow generated by the fan into the combustion chamber 2, and the air outlet pipe discharges the exhaust gas generated after combustion from the combustion chamber 2. For structures and installation methods not described, the existing structure and installation method of the biomass gas tank are adopted.

[0036] When implementing, follow these steps:

[0037] 1) First, the connecting rod 602 and the cam 508 are driven to rotate by the power mechanism 5;

[0038] 2) Then, the connecting rod 602 rotates to drive the crushing blade 603 to rotate and cut and crush the wood waste entering the crushing chamber 3;

[0039] 3) With the rotation of the cam 508 and the expansion and contraction of the spring 703, the slide plate 701 slides back and forth left and right, thereby driving the baffle 704 to move back and forth left and right. The baffle 704 drives the opening 706 to overlap with the feed opening intermittently, so that the crushed wood waste in the crushing chamber 3 evenly enters the combustion chamber 2 for combustion.

[0040] In summary, the biomass gas tank for wood waste, by providing a crushing mechanism 6, can first crush the wood waste entering the combustion chamber 2 for combustion into small particles, thereby increasing the surface area of ​​the wood waste, which makes the contact between oxygen and wood more complete during combustion, thereby improving the combustion speed and efficiency.

[0041] Furthermore, by providing a uniform feeding mechanism 7, the passage 706 can be overlapped with the feeding port of the crushing chamber 3 intermittently, so that the crushed material can enter the combustion chamber 2 at a more uniform speed and quantity, achieving a uniform supply of the crushed wood waste and enabling the waste to be fully burned.
