Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a flow guide cone-shaped grindable biomass block material feeding device. Background Technology

[0002] Biomass boiler fuels are basically classified into bulk, block, and pellet forms. Bucket elevators are commonly used to transport the raw materials into silos, from where they fall through pipes into a screw feeder and then into the furnace for combustion. Bulk fuels are low-cost but difficult to transport, and are prone to clogging in the silo, preventing them from entering the screw feeder. Pellet fuels are uniform in shape, easy to transport, less prone to clogging, and burn well, but are more expensive. Block fuels solve the transportation problem of bulk fuels, are slightly compressed, low-cost, and easy to burn. However, due to their larger size, they are prone to clogging at the silo's descent point. Current technologies often use multi-stage silos to prevent clogging, but the anti-clogging effect is limited, and precise control of the feed volume is difficult.

[0003] Therefore, this utility model innovatively proposes a flow-guiding conical grindable biomass block material feeding device. The rotating mechanism guides the block material to fall in the direction of rotation. During the rotation, the block material is ground by the falling direction of the guide groove and the tower tip structure at the bottom of the hopper, turning large blocks into smaller blocks. The amount of material falling is controlled by controlling the rotation speed and the sealing distance of the device to accurately control the small blocks entering the screw feeder. Utility Model Content

[0004] This invention proposes a guide cone-shaped grinding biomass block material discharge device, which solves the problem in related technologies that large blocks are prone to bulging and clogging at the drop point of the hopper.

[0005] The technical solution of this utility model is as follows: This utility model is a guide cone-shaped grindable biomass block material feeding device, including a bucket elevator feeder and a motor. A sprocket is rotatably connected to the inner side of the bucket elevator feeder. A chain is provided on the circumferential surface of the sprocket. The sprocket is connected to another sprocket through the chain. A feeding box is fixedly connected to the side of the chain. A discharge bin is fixedly connected to the side of the bucket elevator feeder. A screw feeder is fixedly connected to the bottom of the discharge bin. A feed pipe is fixedly connected to the bottom of the screw feeder. A biomass boiler is fixedly connected to one end of the feed pipe. A guide cone device is provided at the bottom of the discharge bin.

[0006] The guide cone device includes a second motor, the bottom of which is fixedly connected to the top of the discharge bin. The output shaft of the second motor is fixedly connected to a first rotating shaft. One end of the first rotating shaft is fixedly connected to a threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A cone block is fixedly connected to the circumferential surface of the threaded sleeve. A third motor is fixedly connected to the side of the screw feeder. The output shaft of the third motor is fixedly connected to a second rotating shaft. A screw feed plate is fixedly connected to the circumferential surface of the second rotating shaft.

[0007] Optionally, there are two sprockets, which are symmetrical to each other along the vertical central axis of the bucket elevator feeder. This can evenly distribute the tension of the chain and avoid chain deviation, slippage, or abnormal wear caused by unilateral force. There are several feeding boxes, which are arranged in a linear array along the side of the chain to improve the efficiency and continuity of material transportation.

[0008] Optionally, the conical block has guide grooves on its circumferential surface. The number of guide grooves is set to several and arranged in a circumferential array on the circumferential surface of the conical block. The several guide grooves are arranged in a circumferential array to form a radial flow channel, which guides the blocky material in the material hopper to the edge of the conical block and avoids the material from accumulating into clumps at the top of the conical block.

[0009] Optionally, the inner side of the feeding bin is provided with protrusions. The number of protrusions is set to several and arranged in a linear array on the inner side of the feeding bin. When the material slides along the surface of the protrusions, the rough surface of the protrusions scrapes the material through friction, further breaking down the material into small pieces, thus achieving a grinding effect.

[0010] Optionally, a dust removal mechanism is provided on the side of the feed pipe. The dust removal mechanism includes a motor four, a rotating shaft three is fixedly connected to the end of the output shaft of the motor four, a fan blade is fixedly connected to the circumferential surface of the rotating shaft three, a locking sleeve is fixedly connected to the end of the rotating shaft three away from the fan blade, a slide bar is slidably connected to the inner side of the feed pipe, a filter screen is fixedly connected to the side of the slide bar, and a handle is fixedly connected to the side of the filter screen.

[0011] Optionally, the inner side of the feed pipe is provided with a sliding groove. There are two sliding grooves, which are symmetrical to each other along the vertical central axis of the feed pipe to ensure that the force is uniform when the slide bar moves, avoid the filter screen from getting stuck due to friction on one side, and ensure the smooth operation of the dust removal mechanism.

[0012] Optionally, two slide bars are provided, and they are symmetrical to each other along the vertical central axis of the filter screen. The slide bars are slidably connected inside the slide groove, and the width of the slide bar is equal to the width of the slide groove, so as to prevent the filter screen from tilting due to unilateral force and avoid local wear between the slide bars and the slide groove.

[0013] Optionally, the fan blades are provided with protrusions on their sides. The number of protrusions is set to several and arranged in a linear array on the side of the fan blades. When the fan blades rotate, the protrusions disrupt the laminar flow state of the airflow and reduce the noise generated by the operation of the fan blades. The number of fan blades is set to several and arranged in a circumferential array on the circumferential surface of the rotating shaft three to form a uniform annular airflow field that covers the entire cross-section of the feed pipe and avoids dust removal dead corners.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, the threaded rod, threaded sleeve, and conical block within the guide cone device work together to move the conical block up and down. Combined with the circumferential guide groove, this guides the biomass lumps to fall evenly and be ground. Working in conjunction with the protrusions in the discharge bin, it crushes the material through impact and friction, preventing blockage. The guide groove also regulates the material trajectory, enhancing the dispersion effect and allowing the material to fall smoothly into the screw feeder, improving discharge efficiency and uniformity, thus laying the foundation for subsequent conveying and combustion.

[0016] 2. In this utility model, the dust collection efficiency is improved and clogging is prevented through the coordinated operation of components such as the rotating shaft, fan blades, and filter screen within the dust removal mechanism. The precise cooperation of the symmetrical sliding grooves and sliding strips ensures stable sliding and sealing of the filter screen, facilitating disassembly and cleaning. This mechanism not only effectively intercepts dust during biomass material transportation and achieves gas-solid separation, but also allows for flexible adaptation to different dust concentrations by adjusting the filter screen position, reducing equipment maintenance costs and ensuring clean and efficient feeding into the biomass boiler.

[0028] Example 1

[0029] Reference Figures 1-5This is the first embodiment of the present invention, which proposes a flow-guiding conical grinding biomass block material feeding device including a bucket elevator feeder 1 and a motor 2. A sprocket 3 is rotatably connected to the inner side of the bucket elevator feeder 1. A chain 4 is provided on the circumferential surface of the sprocket 3. The sprocket 3 is connected to another sprocket 3 through the chain 4. A feeding box 5 is fixedly connected to the side of the chain 4. A discharge bin 6 is fixedly connected to the side of the bucket elevator feeder 1. A screw feeder 7 is fixedly connected to the bottom of the discharge bin 6. A feed pipe 8 is fixedly connected to the bottom of the screw feeder 7. A biomass boiler 9 is fixedly connected to one end of the feed pipe 8. A flow-guiding conical device 10 is provided at the bottom of the discharge bin 6.

[0030] The guide cone device 10 includes a second motor 101, the bottom of which is fixedly connected to the top of the discharge bin 6. The output shaft of the second motor 101 is fixedly connected to a first rotating shaft 102. One end of the first rotating shaft 102 is fixedly connected to a threaded rod 103. The circumferential surface of the threaded rod 103 is threadedly connected to a threaded sleeve 104. The circumferential surface of the threaded sleeve 104 is fixedly connected to a cone block 105. The side of the screw feeder 7 is fixedly connected to a third motor 106. The output shaft of the third motor 106 is fixedly connected to a second rotating shaft 107. The circumferential surface of the second rotating shaft 107 is fixedly connected to a screw feed plate 108.

[0031] There are two sprockets 3, which are symmetrical to each other along the vertical central axis of the bucket elevator feeder 1. This can evenly distribute the tension of the chain 4 and avoid chain 4 deviation, slippage or abnormal wear caused by unilateral force. There are several feeding boxes 5, which are arranged in a linear array on the side of the chain 4 to improve the efficiency and continuity of material transportation.

[0032] The conical block 105 has guide grooves on its circumferential surface. There are several guide grooves arranged in a circumferential array on the circumferential surface of the conical block 105. The guide grooves are arranged in a circumferential array to form a radial flow channel, which guides the block material in the discharge bin 6 to the edge of the conical block 105, and prevents the material from accumulating into clumps on the top of the conical block 105.

[0033] The inner side of the feeding bin 6 is provided with protrusions. There are several protrusions arranged in a linear array on the inner side of the feeding bin 6. When the material slides along the surface of the protrusions, the rough surface of the protrusions scrapes the material through friction, further breaking down the material into small pieces and achieving a grinding effect.

[0034] In this embodiment, the worker feeds the material into the bucket elevator 1 through the feed port on the side of the bucket elevator 1. The motor 2 is remotely started, which drives the sprocket 3 to rotate, causing the chain 4 to rotate as well. This allows the feeding box 5 to receive and transport the material in the bucket elevator 1. The material is then transported to the discharge bin 6 by centrifugal force. The motor 101 is remotely started, which drives the rotating shaft 102 to rotate, causing the threaded rod 103 to rotate. Through the threaded transmission, the threaded sleeve 104 moves axially, thereby realizing the up and down movement of the conical block 105 and achieving the grinding effect on the material. The motor 106 is started, which drives the rotating shaft 107 to rotate, causing the spiral feed plate 108 to smoothly transport the crushed material into the feed pipe 8.

[0035] Example 2

[0036] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a dust removal mechanism 11 is provided on the side of the feed pipe 8. The dust removal mechanism 11 includes a motor 111. The end of the output shaft of the motor 111 is fixedly connected to a rotating shaft 112. A fan blade 113 is fixedly connected to the circumferential surface of the rotating shaft 112. A locking sleeve 114 is fixedly connected to the end of the rotating shaft 112 away from the fan blade 113. A slide bar 115 is slidably connected to the inner side of the feed pipe 8. A filter screen 116 is fixedly connected to the side of the slide bar 115. A handle 117 is fixedly connected to the side of the filter screen 116.

[0037] The inner side of the feed pipe 8 is provided with a sliding groove. There are two sliding grooves, which are symmetrical to each other along the vertical central axis of the feed pipe 8 to ensure that the sliding strip 115 is subjected to uniform force when it moves, to avoid the filter screen 116 from getting stuck due to friction on one side, and to ensure the smooth operation of the dust removal mechanism 11.

[0038] There are two slide bars 115, which are symmetrical to each other along the vertical central axis of the filter screen 116. The slide bars 115 are slidably connected inside the slide groove. The width of the slide bar 115 is equal to the width of the slide groove to prevent the filter screen 116 from tilting due to unilateral force and to avoid local wear between the slide bar 115 and the slide groove.

[0039] The fan blade 113 has protrusions on its side. The number of protrusions is set to several and they are arranged in a linear array on the side of the fan blade 113. When the fan blade 113 rotates, the protrusions disrupt the laminar flow state of the airflow and reduce the noise generated by the operation of the fan blade 113. The number of fan blades 113 is set to several and they are arranged in a circular array on the circumferential surface of the rotating shaft 112 to form a uniform annular airflow field that covers the entire cross section of the feed pipe 8 and avoids dust removal dead corners.

[0040] Compared to Embodiment 1, the motor 111 is started to drive the shaft 112 to rotate, which in turn drives the fan blade 113 to rotate and generate airflow. This airflow, combined with the size of the pores on the filter screen 116, achieves the dust removal effect. The filter screen 116 achieves stable sliding and position adjustment through the precise cooperation between the sliding strips 115 on both sides and the symmetrical sliding grooves in the feed pipe 8. The interception position can be flexibly adjusted according to the dust concentration.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
