[0002] A biomass boiler is a combustion device that uses biomass as fuel, characterized by high efficiency, environmental friendliness, and energy conservation. The boiler generates heat through the combustion of fuel in the furnace, which heats water in the boiler drum to produce steam. After being processed by a superheater and economizer, the steam can be used for heating and power generation.

[0003] Cutting biomass furnaces requires a cutting device, but some biomass furnaces have a cylindrical body. When opening windows or cutting into the furnace body, there is a lack of corresponding fixing mechanisms, making it impossible to effectively fix and limit the biomass furnace. This makes the furnace body prone to shaking during the cutting process, affecting the cutting accuracy. Furthermore, when using plasma cutting equipment, dust is generated, which can easily affect workers and the surrounding environment.

[0004] Therefore, this utility model provides a plasma cutting device for the metal shell of a biomass furnace. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a plasma cutting device for the metal shell of a biomass furnace, including a cutting seat 1 and limiting mechanisms on both sides of its top. The limiting mechanisms include a first limiting frame 2 and a second limiting frame 3, both of which are U-shaped. The first and second limiting frames 2 and 3 are symmetrically and rotatably mounted inside the top of the cutting seat 1. Positioning rods 10 are fixedly installed on the outer walls of the front ends of the first and second limiting frames 2 and 3. A first support mechanism 6 and a second support mechanism 7 are respectively provided on the top of the cutting seat 1 between the first and second limiting frames 2 and 3. An adjusting plate 12 is movably installed on one side of the second support mechanism 7 inside the cutting seat 1 via an adjusting mechanism 5. Dust suction mechanisms 11 are fixedly installed on the front and rear sides of the top of the adjusting plate 12 via support rods 16. The dust collection mechanism 11 includes an arc-shaped dust collection pipe 15. A plasma cutting head 21 is detachably installed on the top of the adjusting plate 12 between the arc-shaped dust collection pipe 15 and the support rod 16. An air inlet side 17 is opened on the opposite side of the arc-shaped dust collection pipe 15 on the front and rear sides. The first limiting frame 2 and the second limiting frame 3 are rotated and adjusted by the hydraulic cylinder 8, so that the first limiting frame 2 and the second limiting frame 3 can be blocked on both sides of the biomass furnace body 4, which can facilitate the limiting of the biomass furnace body 4 and improve the stability of the biomass furnace body 4. Furthermore, the biomass furnace body 4 can be rotated and adjusted by the cooperation of the first support mechanism 6, the second support mechanism 7 and the auxiliary wheel 9, which can facilitate the cutting of the biomass furnace body 4. The dust collection mechanism 11, including the arc-shaped dust collection pipe 15, can perform dust collection, avoiding the impact of dust on the staff and the surrounding environment, thereby improving the practicality of the device.

[0024] In this embodiment, auxiliary wheels 9 are rotatably installed inside the top ends of the first limiting frame 2 and the second limiting frame 3. Hydraulic cylinders 8 are installed at both ends of the first limiting frame 2 and the second limiting frame 3 and the top of the cutting seat 1. A biomass furnace body 4 is arranged between the first limiting frame 2 and the second limiting frame 3. The front end of the biomass furnace body 4 is in close contact with the positioning rod 10. The operation of the hydraulic cylinder 8 can squeeze the first limiting frame 2 and the second limiting frame 3, causing the first limiting frame 2 and the second limiting frame 3 to rotate in the direction of the biomass furnace body 4. This facilitates the limiting of the biomass furnace body 4 by cooperating with the auxiliary wheels 9, thereby improving the stability of the biomass furnace body 4.

[0025] In this embodiment, the auxiliary wheel 9 is in close contact with the outer walls of both sides of the biomass furnace body 4. The biomass furnace body 4 is placed on top of the first support mechanism 6 and the second support mechanism 7. The first support mechanism 6 and the second support mechanism 7 include mounting plates. The mounting plates are symmetrically fixedly arranged on the top of the front and rear ends of the cutting seat 1. A shaft 14 is rotatably installed between the top ends of the two mounting plates on the left side. Rotating wheels 13 are fixedly installed on the inner sides of the mounting plates at both ends of the shaft 14. A servo motor is fixedly installed on the outer wall of the front mounting plate. The output shaft of the servo motor is fixedly connected to one end of the shaft 14. The biomass furnace body 4 is placed on top of the rotating wheel 13. The first support mechanism 6 and the second support mechanism 7 can support the biomass furnace body 4 through the rotating wheel 13. The servo motor and the shaft 14 can drive the rotating wheel 13 to rotate, which facilitates the rotation adjustment of the biomass furnace body 4 and facilitates the subsequent cutting of the biomass furnace body 4.

[0026] In this embodiment, the adjustment mechanism 5 includes a screw 19 and a fixing rod 20. The screw 19 is longitudinally limited and rotatably installed inside the cutting seat 1. The fixing rod 20 is parallel and symmetrically installed on both sides of the screw 19 corresponding to the inner side of the cutting seat 1. The adjustment plate 12 is screwed onto the screw 19 through screw holes in its interior. The adjustment plate 12 is slidably installed onto the fixing rod 20 through sliding holes in its two ends. The adjustment plate 12 is located below the biomass furnace body 4, and the plasma cutting head 21 is located directly below the biomass furnace body 4. The adjustment plate 12 can be longitudinally moved and adjusted by the servo motor and the screw 19, so that the adjustment plate 12 can drive the plasma cutting head 21 to move at the bottom of the biomass furnace body 4, which facilitates cutting along the surface of the biomass furnace body 4. The fixing rod 20 can support and limit the adjustment plate 12, thereby improving the stability of the adjustment plate 12.

[0027] In this embodiment, the support rods 16 are symmetrically fixed on the front and rear sides of the top of the adjusting plate 12. The arc-shaped dust suction pipe 15 is an elastic pipe. The upper surface of the arc-shaped dust suction pipe 15 is in contact with the surface of the biomass furnace body 4. One end of the arc-shaped dust suction pipe 15 is fixedly connected to a negative pressure port 18. The arc-shaped dust suction pipe 15 can deform with the curvature of the surface of the biomass furnace body 4, so that the arc-shaped dust suction pipe 15 can fit into the biomass furnace body 4. It is convenient to set on both sides of the cut and to suction dust, so as to prevent dust from affecting the staff and the surrounding environment.

[0028] When using this plasma cutting device for the metal casing of a biomass furnace, the first limiting frame 2 and the second limiting frame 3 are rotated and adjusted by the hydraulic cylinder 8 and its supporting circuit, causing the first limiting frame 2 and the second limiting frame 3 to rotate to both sides on the top of the cutting seat 1. The biomass furnace body 4 to be cut is placed on top of the first support mechanism 6 and the second support mechanism 7 using a hoisting device. The rotating wheel 13 can contact the biomass furnace body 4. The surface of the rotating wheel 13 is covered with a rubber layer, which increases the friction between the biomass furnace body 4 and the rotating wheel 13. The hydraulic cylinder 8 is controlled by its supporting circuit to push the first limiting frame 2 and the second limiting frame 3 closer to both sides of the biomass furnace body 4. The auxiliary wheel 9 is used to limit the movement, which can improve the stability of the biomass furnace body 4. At the same time, the front end of the biomass furnace body 4 is in close contact with the positioning rod 10. According to the bottom height of the biomass furnace body 4, a pad is added to the bottom of the plasma cutting head 21 to increase the height of the plasma cutting head 21, and a plate is installed on top of it to fix the plasma cutting head 21. At this time, the arc-shaped dust suction pipe 15 is slightly deformed under the pressure of the biomass furnace body 4 and is in close contact with its outer wall. The air inlet side 17 has a dust suction port inside. According to the position on the biomass furnace body 4 that needs to be cut, the servo motor and its matching circuit drive the screw 19 to rotate first, and the screw 19 and the adjusting plate 12 are connected. The screw connection allows the plasma cutting head 21 to be adjusted to the bottom of the front end of the biomass furnace body 4. By adjusting the adjusting plate 12 and the plasma cutting head 21, the plasma cutting head 21 is moved to the cutting position, thus ensuring the accuracy of the cutting position. The negative pressure port 18 is fixedly connected to the dust collection equipment through a pipe, and the plasma cutting head 21 is fixedly connected to the plasma cutting machine. The biomass furnace body 4 is cut by the plasma cutting machine and the plasma cutting head 21. During the cutting process, the servo motor is controlled by the matching circuit of the servo motor to drive the shaft 14 to rotate. The shaft 14 drives the biomass furnace body 4 to rotate slowly clockwise through the rotating wheel 13, or... The servo motor and its associated circuit drive the screw 19, which in turn moves the adjusting plate 12 and the plasma cutting head 21 to the rear end, facilitating the cutting of the biomass furnace body 4. When the dust collection device is working, it draws negative pressure into the arc-shaped dust collection pipe 15 through the negative pressure port 18. The dust around the cut enters the arc-shaped dust collection pipe 15 under negative pressure and then enters the dust collection device through the negative pressure port 18, facilitating the removal of dust generated after cutting and preventing dust from affecting workers and the surrounding environment, thereby improving the practicality of the cutting mechanism. Another servo motor and its associated circuit are installed at the front end of the cutting seat 1, corresponding to the position of the screw 19. The output shaft of this servo motor is fixedly connected to the front end of the screw 19.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
