Description

Technical Field

[0001] The present invention relates to the technical field of combustion conveying equipment, and particularly relates to a biomass bale combustion feeding platform device. Background Art

[0002] In the process of biomass energy utilization, straw, as a renewable energy source, is widely used due to its rich resources and low cost. However, traditional straw combustion equipment generally has serious problems of flue gas leakage during the conveying process. Especially when conveying bale-shaped straw to a combustion boiler, the sealing between the conveying platform and the combustion boiler is poor, resulting in a large amount of flue gas overflowing. 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 plate, further exacerbating the problem of flue gas leakage.

[0003] With the improvement of environmental protection standards and the requirements for the utilization efficiency of biomass energy, the market urgently needs a device that can effectively reduce flue gas leakage during the conveying process. Such a device should have a highly efficient and sealed structural design and be able to adapt to the conveying characteristics of bale-shaped straw. In actual operation, the entry of bale-shaped straw usually requires opening a passage with a certain space. However, too large an opening will cause the flue gas to overflow quickly.

[0004] Therefore, we provide a design that can ensure the smooth conveying of straw while reducing the opening space to meet the high-efficiency and environmental protection production requirements of a biomass bale combustion 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 bale combustion feeding platform device.

[0006] The purpose of the present invention is achieved as follows: A biomass bale combustion feeding platform device includes a support frame. A first transmission mechanism and a second transmission mechanism are respectively arranged inside the support frame, and the first transmission mechanism and the second transmission mechanism are used to convey bale-shaped straw.

[0007] An intermediate mechanism is arranged between the first transmission mechanism and the second transmission mechanism, and the intermediate mechanism transfers the bale-shaped straw from the first transmission mechanism to the second transmission mechanism.

[0008] A combustion boiler mechanism is arranged on the right side of the support frame, and the second transmission mechanism conveys the bale-shaped straw into the combustion boiler mechanism for combustion.

[0009] A box body is arranged on the upper right side of the support frame. The box body is hermetically connected to the support frame, and the right side of the box body is hermetically connected to the combustion boiler mechanism. The box body prevents the flue gas generated inside the combustion boiler mechanism from directly overflowing between the second transmission mechanism and the combustion boiler mechanism.

[0010] A closing mechanism is provided on the left side of the box body. The closing mechanism seals the left end of the box body to prevent flue gas 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 in clearance fit with the first transmission mechanism and the second transmission mechanism.

[0012] Furthermore, a plurality of rotatable roller shafts are distributed on the support plate. The bundled straw is moved onto the support plate through the first transmission mechanism, and the roller shafts on the support plate rotate to drive the bundled straw to move rightward onto the second transmission mechanism.

[0013] When the present invention is in use, the bundled straw is placed on the first transmission mechanism. The first transmission mechanism drives the bundled straw to move rightward onto the support plate. The rotation of the roller shafts drives the bundled straw to move rightward. At this time, a first sensor is provided in the upper left part of the box body. The first sensor identifies that the bundled straw enters the support plate and then transmits a signal to the controller. The controller controls the first lifting mechanism to drive the closing plate to move upward. When the bundled straw completely enters the support plate and does not affect the falling of the closing plate (which can be identified by the first sensor. The above identification and the control of the lifting mechanism by the controller for lifting are prior arts and will not be described in technical details. As long as the above functions can be achieved), the closing plate falls to achieve the relative sealing between the box body, the second transmission mechanism, and the support plate, preventing a large amount of flue gas from overflowing.

[0014] When the bundled straw moves rightward, it squeezes the guiding plate. Since the guiding plate rotates rightward, the moving plate moves rightward and drives the guiding plate on the other side to rotate simultaneously. Since the guiding plate will form an inclined structure after rotation, when the bundled straw continues to move rightward, the reaction force from the guiding plate on the side will cause the bundled straw to move towards the guiding plate on the other side, thereby achieving the maximum limit placement of the bundled straw in the middle position of the box body; during the existing movement of the bundled straw, the lower end of the measuring rod is of an inclined surface structure. When the upper end of the bundled straw moves rightward, it pushes the measuring rod upward. The second sensor measures the upward movement distance of the measuring rod and transmits the measured signal to the controller. The controller calculates the height of the bundled straw and controls the second lifting mechanism to drive the second lifting plate 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 bundled straw; 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 flue gas inside from overflowing; that is, the double-layer structure for preventing flue gas overflow can block the flue gas with the lifting plate when the bundled straw enters the box body, and then move the lifting plate upward after the closing plate falls, which can greatly reduce the overflow of flue gas.

[0015] The driving mechanism is controlled by a controller to drive the stop rod to move up and down, so that the lower end of the stop rod is located at a position close to the top of the bundled straw. At this time, when the bundled straw continues to move to the right, the bundled straw 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 strip rod above, the strip rod on the upper part of the upper opening and closing plate is prevented from rotating to the right, reducing the number of strip rods on the opening and closing plate rotating to the right, and avoiding the opening becoming too large due to the excessive rotation of the strip rods on the opening and closing plate, resulting in smoke overflow.

[0016] During the rotation of the guide plate, the extrusion rod squeezes the moving rod to move outward. At this time, the U-shaped stop rod moves outward, and the second spring is stretched. 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 bundled straw continues to move to the right, the bundled straw squeezes the strip rods on the left and right 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 number of strip rods on the opening and closing plate rotating to the right, and avoiding the opening becoming too large due to the excessive rotation of the strip rods on the opening and closing plate, resulting in smoke overflow.

[0017] Beneficial effects: The device can transport the bundled straw into the combustion boiler structure, and is provided with a double-layer closed structure, which 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 dispersion of smoke. By adopting the double-layer closed structure, the sealing performance during the transportation process is greatly improved, and the leakage of smoke can be effectively reduced. 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 dispersion. Compared with the traditional single-layer closed or non-closed design, this solution not only significantly improves the working environment, but also improves the environmental protection performance of the equipment, providing important technical support for the development of biomass combustion technology.

[0027] In Embodiment 1, as shown in Figure 1 —7, the object of the present invention is achieved as follows: A biomass bundle burning feeding platform device includes a support frame 1, in which a first transmission mechanism 2 and a second transmission mechanism 8 are respectively arranged. The first transmission mechanism 2 and the second transmission mechanism 8 are used to convey a bundle of straw 3;

[0028] A transition mechanism is arranged between the first transmission mechanism 2 and the second transmission mechanism 8, and the transition mechanism transfers the bundle of straw 3 from the first transmission mechanism 2 to the second transmission mechanism 8;

[0029] A combustion boiler mechanism 6 is arranged on the upper right side of the support frame 1. The second transmission mechanism 8 conveys the bundle of straw 3 into the combustion boiler mechanism 6 for combustion. The combustion boiler mechanism 6 is prior art and is not technically restricted, as long as it can cooperate with the technical solution of this application;

[0030] The first transmission mechanism 2 and the second transmission mechanism 8 are prior art and can realize the transmission of the bundle of straw 3 and have a certain heat and fire resistance function.

[0031] A box body 5 is arranged on the upper right side of the support frame 1. The box body 5 is hermetically connected to the support frame 1, and the right side of the box body 5 is hermetically connected to the combustion boiler mechanism 6. The box body 5 prevents the flue gas generated in the combustion boiler mechanism 6 from directly overflowing between the second transmission mechanism 8 and the combustion boiler mechanism 6;

[0032] A sealing mechanism is arranged on the left side of the box body 5, and the sealing mechanism seals the left end of the box body 5 to prevent flue gas from overflowing from the left end of the box body 5.

[0033] In addition, in order to prevent the overflow of flue gas, a blower can be arranged below the first transmission mechanism 2 and the second transmission mechanism 8 to blow air inward, avoiding the overflow of a large amount of flue gas. At the same time, a blower can be arranged at the interface between the combustion boiler mechanism 6 and the second transmission mechanism 8 to blow air into the combustion boiler mechanism 6.

[0034] The transition mechanism includes a support plate 23. The front and rear ends of the support plate 23 are fixedly connected to the support frame 1, and the left and right ends of the support plate 23 are in clearance fit with the first transmission mechanism 2 and the second transmission mechanism 8 respectively. A plurality of rotatable roller shafts 24 are distributed on the support plate 23. The rotation of the roller shafts 24 is prior art and not limited by technology as long as the above functions can be achieved. The bundled straw 3 is moved to the support plate 23 through the first transmission mechanism 2, and the roller shafts 24 on the support plate 23 rotate to drive the bundled straw 3 to move rightward onto the second transmission mechanism 8.

[0035] The closing mechanism includes a closing plate 4. A strip-shaped groove is opened in the upper part of the left end of the box body 5, and the closing plate 4 is movably located in the strip-shaped groove up and down. A first lifting mechanism 9 is fixedly arranged on the box body 5, and the first lifting mechanism 9 drives the closing plate 4 to move up and down. The connection mode between the first lifting mechanism 9 and the closing plate 4 is not limited by technology.

[0036] A first sensor is arranged on the inner side surface of the left end of the box body 5. The first sensor is located on the left side of the closing mechanism. The bundled straw 3 can be detected through the first sensor, and after detecting the bundled straw 3, the signal is transmitted to the controller and then to the first lifting mechanism 9.

[0037] An adjusting mechanism is arranged in the box body 5 to place the bundled straw 3 in the middle position of the box body 5. The adjusting mechanism includes two symmetrically distributed guiding plates 21. The outer ends of the guiding plates 21 are rotatably connected to the box body 5. The guiding plates 21 can rotate to the right simultaneously, thereby placing the bundled straw 3 in the middle position of the box body 5 to the maximum extent.

[0038] Two fixing bars 18 are fixedly arranged at the upper end inside the box body 5. Two round bars are fixedly arranged between the two fixing bars 18. A moving plate 17 is movably arranged on the round bars. A first spring 16 is sleeved on the round bar between the moving plate 17 and the right fixing bar 18. Two limiting rods 20 are symmetrically arranged on the moving plate 17. Moving grooves are opened on the upper surface of the guiding plates 21, and the lower ends of each limiting rod 20 are respectively located in the moving grooves of the corresponding guiding plates 21, and the lower ends of the limiting rods 20 can move along the moving grooves.

[0039] A secondary closing mechanism is movably arranged up and down in the box body 5. The secondary closing mechanism includes a lifting plate 7. A lifting groove is opened at the upper end of the box body 5, and the lifting plate 7 is movably located in the lifting groove up and down. A second lifting mechanism 12 is arranged on the upper surface of the box body 5, and the second lifting mechanism 12 drives the lifting plate 7 to move up and down.

[0040] The lower end of the lifting plate 7 is provided with an opening and closing mechanism. The opening and closing mechanism includes three opening and closing plates. A pair of the opening and closing plates are symmetrically arranged on the left and right respectively, and the other opening and closing plate is connected to the lower end of the lifting plate 7. A plurality of strip-shaped rods are evenly distributed in the opening and closing plates. The strip-shaped rods are rotatably connected to each other, and torsion springs are arranged between the strip-shaped rods. When not under force, under the elastic force of the torsion springs, the plurality of strip-shaped rods are located in the same plane. The above-described manner of combining the strip-shaped rods into the opening and closing plates is not limited technically, as long as the above functions can be achieved.

[0041] Chamfers are respectively opened at both ends of the inner side of the opening and closing plates. The opening and closing plates on the left and right sides are in contact connection with the opening and closing plate above. The three opening and closing plates form a rectangular structure, and the three corresponding strip-shaped rods among them also form a straw structure. The outermost strip-shaped rod in the opening and closing plates on the left and right sides is fixedly connected to the lifting plate 7.

[0042] A stop rod 25-1 that can move up and down is arranged on the right side of the lifting plate 7. The upper end of the stop rod 25-1 penetrates through the upper surface of the box body 5. A threaded sleeve is rotatably arranged on the upper surface of the box body 5. The stop rod 25 is threadedly penetrated through the threaded sleeve. A driving mechanism 15 is arranged on the upper surface of the box body 5. The driving mechanism 15 drives the threaded sleeve to rotate, thereby driving the stop rod 25 to move up and down. The lower end of the stop rod 25 is attached to the right side surface of the upper opening and closing plate.

[0043] An extrusion rod 28 is rotatably arranged on the upper surface of the inner end of the guiding plate 21. U-shaped stop rods that can move back and forth are symmetrically arranged on the front and rear side surfaces of the box body 5 respectively. The left and right ends of the U-shaped stop rods penetrate through the box body 5 respectively in a manner that can move back and forth. The left and right ends of the U-shaped stop rods are respectively located on the left and right sides of the lifting plate 7. The right end of the U-shaped stop rod is attached to the right side surface of the side opening and closing plate. A moving rod 27 is fixedly arranged at the left end of the U-shaped stop rod. The moving rod 27 is located outside the extrusion rod 28. Spring two 26 is respectively arranged 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 that can move up and down is arranged on the box body 5. The upper part of the measuring rod 19 penetrates through the box body 5 in a manner that can move up and down. The lower end of the measuring rod 19 is a structure that slopes to the right. A spring three 14 is sleeved 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 arranged on the upper surface of the box body 5. A sensor two 10 is arranged on the support rod 11.

[0045] When the present invention is in use, the bundled straw 3 is placed on the first transmission mechanism 2. The first transmission mechanism 2 drives the bundled straw 3 to move rightward onto the support plate 23. The rotation of the roller shaft 24 drives the bundled straw 3 to move rightward. At this time, a first sensor is provided at the upper left side inside the box body 5. The first sensor identifies that the bundled straw 3 enters the support plate 23 and then transmits a signal to the controller. The controller controls the first lifting mechanism 9 to drive the closing plate 4 to move upward. When the bundled straw 3 completely enters the support plate 23 and does not affect the falling of the closing plate 4 (which can be identified by the first sensor. The above identification and the control of the lifting mechanism to lift and lower by the controller are prior arts and will not be described in technical details. As long as the above functions can be achieved), the closing plate 4 falls, realizing the relative sealing between the box body 5, the second transmission mechanism 8, and the support plate 23, and avoiding a large amount of flue gas from overflowing.

[0046] When the bundled straw 3 moves rightward, it squeezes the guiding plate 21. Since the guiding plate 21 rotates rightward, the moving plate 17 moves rightward and drives the guiding plate 21 on the other side to rotate simultaneously. Since the guiding plate 21 will form an inclined structure after rotation, when the bundled straw 3 continues to move rightward, the reaction force from the guiding plate 21 on the side will cause the bundled straw 3 to move toward the guiding plate 21 on the other side, thereby realizing the maximum limit placement of the bundled straw 3 at the middle position of the box body 5. During the existing movement of the bundled straw 3, the lower end of the measuring rod 19 is of an inclined surface structure. When the upper end of the bundled straw 3 moves rightward, it jacks up the measuring rod 19. The second sensor 10 measures the upward movement distance of the measuring rod 19 and transmits the measured signal to the controller. The controller calculates the height of the bundled straw 3 and controls the second lifting mechanism 12 to drive the lifting plate 7 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 bundled straw 3. When the lifting plate 7 does not move upward, the lower end of the lifting plate 7 fits with the upper end of the support plate 23, avoiding a large amount of flue gas from overflowing inside. That is, the double-layer structure for preventing flue gas from overflowing can block the flue gas with the lifting plate 7 when the bundled straw 3 enters the box body 5. After the closing plate 4 falls, the lifting plate 7 is moved upward again, which can greatly reduce the overflow of flue gas.

[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 close to the upper part of the top of the bundled straw 3. At this time, when the bundled straw 3 continues to move rightward, the bundled straw 3 squeezes the strip-shaped rod on the upper opening and closing plate to rotate rightward. At the same time, due to the limiting effect of the lower end of the stop rod 25 on the strip-shaped rod on the upper part, it avoids the strip-shaped rod on the upper part of the opening and closing plate from rotating rightward, reducing the number of strip-shaped rods on the opening and closing plate rotating rightward, and avoiding the opening becoming too large due to the excessive number of strip-shaped rods on the opening and closing plate rotating, resulting in flue gas overflowing.

[0048] During the rotation of the guide plate 21, the extrusion rod 28 extrudes the moving rod 27 to move outward. At this time, the U-shaped stop rod moves outward, and the second spring 26 is stretched. 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 bundled straw 3 continues to move to the right, the bundled straw 3 squeezes the strip-shaped rods on the opening and closing plates on both 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-shaped rod, it is avoided that the strip-shaped rod on the upper part of the outer opening and closing plate also rotates to the right, reducing the number of strip-shaped rods on the opening and closing plate that rotate to the right, and avoiding that the excessive rotation of the strip-shaped rods on the opening and closing plate causes too large an opening and the smoke to overflow.
