Description

Technical Field

[0001] The invention relates to the technical field of combustion and conveying equipment, and in particular to a biomass bundle combustion and conveying platform device. Background Art

[0002] In the process of biomass energy utilization, straw is widely used as a renewable energy source due to its abundant resources and low cost. However, traditional straw burning equipment generally has serious problems with smoke emission during transportation. Especially when transporting bundled straw to the combustion boiler, the airtightness between the conveying platform and the combustion boiler is poor, resulting in a large amount of smoke overflow. This not only affects the air quality of the working environment, but also increases the threat to the health of operators. In addition, some equipment fails to effectively control the opening space in the design of the opening and closing panels, further exacerbating the problem of smoke emission.

[0003] With the improvement of environmental protection standards and the requirement for biomass energy utilization efficiency, the market urgently needs a device that can effectively reduce smoke emission during transportation. Such a device should have an efficient and closed structural design and be able to adapt to the characteristics of straw bundle transportation. In actual operation, the entry of straw bundles usually requires a certain space to be opened. However, an overly large opening will cause smoke to overflow quickly.

[0004] To this end, we provide a design that can reduce the opening space while ensuring smooth straw transportation, so as to meet the production needs of efficient and environmentally friendly biomass bale burning feeding platform device. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a biomass bundle burning feeding platform device.

[0006] The object of the present invention is achieved as follows: A biomass bundle burning feeding platform device comprises a support frame, wherein a transmission mechanism 1 and a transmission mechanism 2 are respectively arranged in the support frame, and the transmission mechanism 1 and the transmission mechanism 2 are used to transmit bundled straw;

[0007] A transition mechanism is provided between the transmission mechanism 1 and the transmission mechanism 2, and the transition mechanism transfers the bundled straw from the transmission mechanism 1 to the transmission mechanism 2;

[0008] A combustion boiler mechanism is arranged on the right side of the support frame, and a transmission mechanism 2 transports the bundled straw to the combustion boiler mechanism for combustion;

[0009] A box is provided on the upper right side of the support frame, the box is sealed to the support frame, and the right side of the box is sealed to the combustion boiler mechanism, so that the box prevents the flue gas generated in the combustion boiler mechanism from directly overflowing from between the transmission mechanism 2 and the combustion boiler mechanism;

[0010] A closing mechanism is arranged on the left side of the box body, and the closing mechanism seals the left end of the box body to prevent smoke from overflowing from the left end of the box body.

[0011] Furthermore, the transition mechanism includes a support plate, the front and rear ends of the support plate are fixedly connected to the support frame, and the left and right ends of the support plate are respectively clearance-matched with the transmission mechanism 1 and the transmission mechanism 2.

[0012] Furthermore, a plurality of rotatable rollers are distributed on the support plate, and the bundle of straw is moved to the support plate through the transmission mechanism 1, and the rollers on the support plate rotate to drive the bundle of straw to move rightward to the transmission mechanism 2.

[0013] When the present invention is in use, the bundle of straw is placed on the transmission mechanism 1, and the transmission mechanism 1 drives the bundle of straw to move rightward to the support plate, and the rotation of the roller drives the bundle of straw to move rightward. At this time, a sensor 1 is arranged on the upper left side of the box body, and the sensor 1 identifies that the bundle of straw enters the support plate, and then transmits a signal to the controller. The controller controls the lifting mechanism 1 to drive the closing plate to move upward. When the bundle of straw completely enters the support plate and does not affect the falling of the closing plate (it can be identified by the sensor 1, and the above identification and the lifting and lowering of the lifting mechanism controlled by the controller are prior arts and will not be described in detail. It is sufficient to achieve the above functions), the closing plate falls to achieve relative sealing between the box body, the transmission mechanism 2 and the support plate to avoid a large amount of smoke overflow.

[0014] When the bundle of straw moves to the right, the guide plate is squeezed. As the guide plate rotates to the right, the moving plate moves to the right and drives the guide plate on the other side to rotate at the same time. Since the guide plate will become an inclined structure after rotation, when the bundle of straw continues to move to the right, the reaction force of the guide plate on the side will cause the bundle of straw to move toward the guide plate on the other side, thereby placing the bundle of straw in the middle position of the box with the maximum limit. In the existing movement of the bundle of straw, the lower end of the measuring rod is an inclined structure. When the upper end of the bundle of straw moves to the right, the measuring rod is lifted upward, and the distance moved upward by the measuring rod is measured by two pairs of sensors. The controller measures the height of the straw bundle, controls the lifting mechanism 2 by the controller to drive the lifting plate 2 to move upward by a certain distance, so that the vertical center position between the left and right opening and closing plates is located in the middle of the height of the straw bundle; when the lifting plate does not move upward, the lower end of the lifting plate fits with the upper end of the support plate to prevent a large amount of smoke from overflowing; that is, the double-layer structure to prevent smoke from overflowing can block the smoke when the straw bundle enters the box, and move the lifting plate upward after the closing plate falls, which can greatly reduce the overflow of smoke.

[0015] The controller controls the driving mechanism to drive the stop rod to move up and down, so that the lower end of the stop rod is located near the top of the straw bundle; at this time, when the straw bundle continues to move to the right, the straw bundle squeezes the strip rod on the upper opening and closing plate to rotate to the right. At the same time, due to the limiting effect of the lower end of the stop rod on the upper strip rod, the strip rod on the upper part of the upper opening and closing plate is prevented from rotating to the right, thereby reducing the amount of rotation of the strip rod on the opening and closing plate to the right, and preventing the strip rod on the opening and closing plate from rotating too much, resulting in an excessively large opening and causing smoke to overflow.

[0016] When the guide plate rotates, the extrusion rod squeezes the moving rod and moves it outward. At this time, the U-shaped stop rod moves outward, spring two is pulled, and the right end of the U-shaped stop rod fits with a part of the right side of the corresponding opening and closing plate. When the bundle of straw continues to move to the right, the bundle of straw squeezes the strip rods on the left and right sides of the opening and closing plates to make them rotate. At the same time, due to the limiting effect of the inner end of the U-shaped stop rod on the outer strip rod, the strip rod on the upper part of the outer opening and closing plate is prevented from rotating to the right, reducing the amount of rotation of the strip rod on the opening and closing plate to the right, and avoiding excessive rotation of the strip rod on the opening and closing plate, resulting in excessive opening and smoke overflow.

[0017] Beneficial effects: The device can transport the bundled straw into the combustion boiler structure, and the double-layer closed structure can greatly reduce the overflow of smoke. In addition, when the bundled straw enters the right side of the box, the opening angle (space) of the opening and closing plate can be minimized to reduce the emission of smoke. By adopting a double-layer closed structure, the sealing of the transportation process is greatly improved, which can effectively reduce the leakage of smoke. At the same time, when the bundled straw enters the right side of the box, the design of the opening and closing plate minimizes its opening angle, thereby further reducing the possibility of smoke emission. Compared with the traditional single-layer closed or unclosed design, this solution not only significantly improves the working environment, but also improves the environmental performance of the equipment, providing important technical support for the development of biomass combustion technology.

[0041] The two ends of the inner side of the opening and closing plates are chamfered, and the opening and closing plates on the left and right sides are in contact with the opening and closing plates above. The three opening and closing plates form a rectangular structure, and the three corresponding strip rods therein also correspond to the straw structure. The outermost strip rods of the opening and closing plates on the left and right sides are fixedly connected to the lifting plate 7.

[0042] A stop rod 25-which can move up and down is arranged on the right side of the lifting plate 7, and the upper end of the stop rod 25-passes through the upper surface of the box body 5, and a threaded sleeve is rotatably arranged on the upper surface of the box body 5, and the stop rod 25 threadably passes through the threaded sleeve, and a driving mechanism 15 is arranged on the upper surface of the box body 5, and the driving mechanism 15 drives the threaded sleeve to rotate, thereby driving the stop rod 25 to move up and down, and the lower end of the stop rod 25 is in contact with the right side surface of the upper opening and closing plate.

[0043] A squeezing rod 28 is rotatably provided on the upper surface of the inner end of the guide plate 21, and a U-shaped stop rod is symmetrically provided on the front and rear sides of the box body 5 which can move forward and backward respectively. The left and right ends of the U-shaped stop rod can respectively move forward and backward and penetrate the box body 5, and the left and right ends of the U-shaped stop rod are respectively located on the left and right sides of the lifting plate 7, and the right end of the U-shaped stop rod is in contact with the right side surface of the opening and closing plate on the side, and a moving rod 27 is fixedly provided on the left end of the U-shaped stop rod, and the moving rod 27 is located on the outside of the squeezing rod 28, and springs 26 are respectively provided between the left and right ends of the U-shaped stop rod and the outer side surface of the box body 5.

[0044] A measuring rod 19 is provided on the box body 5 so as to be movable up and down. The upper part of the measuring rod 19 can be moved up and down and penetrates the box body 5. The lower end of the measuring rod 19 is a structure inclined to the right. A spring three 14 is installed on the measuring rod 19 between the upper end of the measuring rod 19 and the upper surface of the box body 5. A support rod 11 is fixedly provided on the upper surface of the box body 5, and a sensor two 10 is provided on the support rod 11.

[0045] When the present invention is in use, the bundle of straw 3 is placed on the transmission mechanism 2, and the bundle of straw 3 is driven to move rightward to the support plate 23 by the transmission mechanism 2, and the bundle of straw 3 is driven to move rightward by the rotation of the roller 24. At this time, a sensor 1 is arranged on the upper left side of the box body 5, and the sensor 1 identifies that the bundle of straw 3 enters the support plate 23, and then transmits a signal to the controller, and the controller controls the lifting mechanism 9 to drive the closing plate 4 to move upward. When the bundle of straw 3 completely enters the support plate 23 and does not affect the falling of the closing plate 4 (it can be identified by the sensor 1, and the above identification and the lifting and lowering of the lifting mechanism controlled by the controller are prior arts and will not be described in detail. It is sufficient to achieve the above functions), the closing plate 4 falls to achieve relative sealing between the box body 5, the transmission mechanism 2 8 and the support plate 23 to avoid a large amount of smoke overflow.

[0046] When the bundle of straw 3 moves to the right, the guide plate 21 is squeezed. As the guide plate 21 rotates to the right, the movable plate 17 moves to the right and drives the guide plate 21 on the other side to rotate at the same time. Since the guide plate 21 will become an inclined structure after rotation, when the bundle of straw 3 continues to move to the right, the reaction force of the guide plate 21 on the side will cause the bundle of straw 3 to move toward the guide plate 21 on the other side, thereby placing the bundle of straw 3 in the middle position of the box body 5 with the maximum limit. In the existing movement process of the bundle of straw 3, the lower end of the measuring rod 19 is an inclined structure. When the upper end of the bundle of straw 3 moves to the right, the measuring rod 19 is lifted upward, and the measuring rod 10 is measured by the sensor 10. 9 measures the distance moved upward, and transmits the measured signal to the controller, the controller measures the height of the bundle of straw 3, and controls the lifting mechanism 12 through the controller to drive the lifting plate 72 to move upward a certain distance, so that the vertical center position between the left and right opening and closing plates is located at the middle position of the height of the bundle of straw 3; when the lifting plate 7 does not move upward, the lower end of the lifting plate 7 is in contact with the upper end of the support plate 23 to prevent a large amount of smoke from overflowing therefrom; that is, the double-layer structure to prevent smoke from overflowing can block the smoke when the bundle of straw 3 enters the box body 5, and after the closing plate 4 falls, the lifting plate 7 is moved upward, which can greatly reduce the overflow of smoke.

[0047] The controller controls the driving mechanism 15 to drive the stop rod 25 to move up and down, so that the lower end of the stop rod 25 is located near the top of the straw bundle 3; at this time, when the straw bundle 3 continues to move to the right, the straw bundle 3 squeezes the strip rod on the upper opening and closing plate to rotate to the right. At the same time, due to the limiting effect of the lower end of the stop rod 25 on the upper strip rod, the strip rod on the upper part of the upper opening and closing plate is prevented from rotating to the right, reducing the amount of rotation of the strip rod on the opening and closing plate to the right, and avoiding excessive rotation of the strip rod on the opening and closing plate, resulting in an excessively large opening and smoke overflow.

[0048] During the rotation of the guide plate 21, the squeezing rod 28 squeezes the moving rod 27 and moves it outward. At this time, the U-shaped stop rod moves outward, the spring 26 is pulled, and the right end of the U-shaped stop rod fits with a part of the right side surface of the corresponding opening and closing plate. When the bundle of straw 3 continues to move to the right, the bundle of straw 3 squeezes the strip rods on the opening and closing plates on the left and right sides to make them rotate. At the same time, due to the limiting effect of the inner end of the U-shaped stop rod on the outer strip rod, the strip rod on the upper part of the outer opening and closing plate is prevented from rotating to the right, reducing the amount of rotation of the strip rod on the opening and closing plate to the right, and avoiding excessive rotation of the strip rod on the opening and closing plate, resulting in an excessive opening and smoke overflow.
