Description

Technical Field

[0001] This invention relates to the field of material conveying technology, and more specifically to a storage and activation bin for bulk materials. Background Technology

[0002] Currently, coal silo blockage is a common phenomenon in the thermal power generation industry. Coal-fired power plants transport fuel coal to the coal silo via conveyor belts, and the silo is designed to store coal for several hours. At the bottom of the silo is a weighing feeder used to weigh and measure the amount of coal delivered to each coal mill. When the moisture content of the raw coal increases, when the composition of the raw coal fluctuates, or when other fuels such as sludge are mixed in, coal silo blockage is likely to occur, causing feeder interruptions and leading to emergency shutdowns of the coal mills and other production accidents. Coal silo blockage is a key factor restricting the stable power generation and heating supply of coal-fired power plants, and it is also a problem that is currently difficult to avoid in the fuel systems of coal-fired power plants.

[0003] Currently, there are several main methods for clearing blockages in bulk material silos: First, using rotating blades on the silo wall to mechanically scrape and clear the blockage, preventing the material from arching or bridging on the inner wall of the hopper. Second, using multiple liners driven by hydraulic or electro-hydraulic actuators to disturb the blockage and promote the material's fall. Third, using low-frequency air hammers to vibrate areas prone to blockage, or using multiple air cannons to vibrate and discharge materials that may cause blockages, thus disturbing the material's fall.

[0004] Among these methods, rotary scraper-type unblocking equipment, installed in the middle of the silo, suffers from severe wear, short lifespan, high investment costs, and occupies internal space. Electro-hydraulic actuator unblocking also suffers from the problems of requiring numerous units, making it difficult to achieve close integration with the raw coal silo, inaccurate control of the unblocking area, and poor unblocking effect. Air cannon unblocking has a limited unblocking area, and due to the uncertainty of the arching location, multiple air cannons are needed. When the raw coal in the power plant has a high moisture content, air energy transfer is poor, resulting in a mediocre arch-breaking effect and poor overall performance. Low-frequency air hammer rapping equipment is used only after a blockage is about to occur or has already occurred. While it has a large rapping force and multiple rapping points, it tends to compact material at the bottom, leading to poor results.

[0005] It is evident that current methods for activating and clearing blockages in bulk material silos suffer from technical problems such as high equipment costs, large space occupation within the silo, and poor clearing effect. Summary of the Invention

[0006] To address the technical problems of current activation and unblocking methods for bulk material silos, such as high equipment costs, large space occupation within the silo, and poor unblocking effect, this invention provides a storage activation silo for bulk materials.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments and features of the present invention can be combined with each other.

[0030] The following description sets forth many specific details in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments described in the specification are only some, not all, of the embodiments of the invention.

[0031] Combination Figures 1 to 4 As shown, the storage and activation chamber for bulk materials provided in this embodiment of the invention includes a chamber body 1 and a feeding rod 2.

[0032] like Figure 1As shown, the silo body 1 includes a receiving section 11 and a discharging section 12 located below the receiving section 11. The receiving section 11 has a first cavity 111 inside, and the top of the receiving section 11 is provided with a feed inlet 112 communicating with the first cavity 111. Materials can enter the first cavity 111 through the feed inlet 112. The feeding section 12 includes a semi-cylindrical plate 121 and two semi-conical plates 122 opposite to each other on both sides of the semi-cylindrical plate 121. The semi-cylindrical plate 121 and the two semi-conical plates 122 form a second cavity 123 that communicates with the first cavity 111. The bottom of the semi-cylindrical plate 121 has a discharge port 124 that communicates with the second cavity 123. In use, the material input through the first cavity 111 flows to the second cavity 123, and guided by the slope of the semi-cylindrical plate 121 and the two semi-conical plates 122, the material will flow to the discharge port 124 and be conveyed to a designated position through the conveying port. The two sides of the semi-cylindrical plate 121 are connected to the sides of the semi-conical plates 122, and the tops of both ends of the semi-cylindrical plate 121 and the top of the semi-conical plates 122 are connected to the bottom of the receiving section 11. The inclination angle of the semi-conical plates 122 should be greater than 50° to ensure that the material slides freely. Furthermore, the width of the semi-cylindrical plate 121 is adapted to the size of the discharge port 124, that is, the width of the semi-cylindrical plate 121 should be slightly larger than the size of the discharge port 124, to ensure that the material on the semi-cylindrical plate 121 falls down in time without clogging.

[0033] Combination Figure 2 and Figure 3As shown, the feeding rod 2 includes a drive section 21 and a feeding section. The drive section 21 is rotatably mounted on the side wall of the chamber 1. Specifically, the drive section 21 is rotatably mounted on the inner wall of the chamber 1 via bearings to increase the smoothness of the rotation of the drive section 21. The drive section 21 can be driven by a drive assembly. The drive assembly can be a drive motor or a combination of a drive motor and a reducer, and can be designed according to actual needs. The drive section 21 can be rotatably mounted on the semi-conical plate 122, or the drive section 21 can be rotatably mounted at the connection position between the semi-conical plate 122 and the receiving section 11. The axis of the drive section 21 coincides with the axis of the semi-conical plate 121. The drive section 21 is used to drive the feeding section to rotate, and part of the rotation trajectory of the feeding section is in contact with the inner wall of the second cavity 123. In this design, when the feeding section is rotating and inside the second cavity 123, it can conform to the inner wall of the second cavity 123. The driving section 21 rotates along the axis of the semi-cylindrical plate 121, causing it to rotate along the inner wall of the second cavity 123. Specifically, the feeding section will rotate along the inner walls of the semi-cylindrical plate 121 and the two semi-conical plates 122, scraping away material from the inner walls of these plates. At this time, the feeding section itself can be used as a scraper to remove material from the inner wall of the second cavity 123. Alternatively, a scraper can be placed on the side of the feeding section facing the inner wall of the second cavity 123 to scrape away material from the inner wall of the second cavity 123. These are not limiting factors.

[0034] The storage and activation chamber provided by this invention does not require a complex structure, reducing equipment costs. The drive section 21 of the feeding rod 2 is located on the side wall of the chamber body 1, and the feeding section is attached to the inner wall of the second cavity 123, reducing space occupation and avoiding affecting the material holding capacity. The feeding section 12 of the chamber body 1 adopts a semi-cylindrical plate 121 and two semi-conical plates 122 in combination, so that the material can move towards the discharge port 124. At the same time, the feeding section can rotate along the inner wall of the second cavity 123 to scrape the material at the bottom and sides of the second cavity 123, avoiding the phenomenon of blockage of the discharge port 124, improving the stability of material conveying, and ensuring the stable operation of the fuel system.

[0035] Combination Figure 2 and Figure 3 As shown, the feeding rod 2 has two drive sections 21, which are respectively located on corresponding sides of the two chambers 1, and the axes of the two drive sections 21 coincide. The feeding section includes two feeding section bodies 22, which are respectively mounted on the two drive sections 21. In this design, the feeding rod 2 adopts a split design, which increases the convenience of processing the feeding rod 2. At the same time, it avoids the phenomenon of the feeding section breaking due to its excessive length, thus increasing the service life of the feeding rod 2.

[0036] In some implementations, such as Figure 2 As shown, the two feeding section bodies 22 are arranged in a mirror image, that is, the axes of the two feeding section bodies 22 coincide. In this design, the two feeding rod bodies 2 are arranged radially along the plane of symmetry in the radial direction of the semi-cylindrical plate 121, so that the two driving sections 21 drive the two feeding section bodies 22 to rotate synchronously, ensuring the uniformity of the feeding rods 2 in stirring the material.

[0037] In other implementations, such as Figure 3 As shown, the two feeding section bodies 22 are symmetrically arranged along the axis of the drive section 21, and the two feeding section bodies 22 rotate at a 180° interval. With this design, the two feeding plate bodies can maintain a stable 180° angle to alternately feed the material, increasing the material's range of motion.

[0038] like Figure 4 As shown, the feeding section body 22 includes a first rod 221 connected to the outer periphery of the driving section 21 and a second rod 222 connected to the first rod 221. The first rod 221 protrudes in the direction of rotation of the driving section 21, the second rod 222 extends in the horizontal direction, and the end of the second rod 222 is inclined in the direction of rotation away from the second rod 222.

[0039] Specifically, since the inner wall of the semi-conical plate 122 is arc-shaped, the first rod 221, which can fit against the inner wall of the semi-conical plate 122, should also be arc-shaped. Simultaneously, the first rod 221 is also curved along the circumferential direction of the semi-conical plate 121, thus using a segment of a logarithmic spiral as its extension trajectory. The second rod 222 is located at the end of the first rod 221, allowing it to fit against the inner wall of the semi-conical plate 121. The end of the second rod 222 is slightly tilted backward, enabling it to push the material towards the discharge port 124, ensuring efficient material feeding.

[0040] The length of each second rod 222 should be approximately half the width of the semi-cylindrical plate 121 to avoid interference between the two second rods 222. With this design, the material-dispersing rod 2 body can disperse the material to the outer edge during rotation, effectively preventing jamming and increasing the dispersion effect of the material at the bottom of the second cavity 123. Simultaneously, it prevents the material-dispersing rod 2 body from bearing excessive force, thus increasing its service life.

[0041] Combination Figures 1 to 4As shown, the receiving section 11 includes a first housing 113 connected to the unloading section 12 and a second housing 114 disposed above the first housing 113. The height of the first housing 113 is greater than the radius of the drive section 21 to facilitate the installation of the drive section 21. The top of the second housing 114 is provided with a first flange 115 for connecting to the input pipe. The silo 1 of this application can be installed at the bottom of the raw coal silo, that is, the bottom of the raw coal silo is provided with an input pipe, and the top of the silo 1 is connected to the input pipe through the first flange 115 to increase the connection strength. The two silos 1 of this application can be separated from the raw coal silo above them by a gate valve or a bar valve for convenient maintenance.

[0042] In some embodiments, the first housing 113 includes two first straight plates 1131 and two side plates 1132 arranged opposite to each other. The two first straight plates 1131 are respectively connected to both ends of the semi-cylindrical plate 121, and the two side plates 1132 are connected to two semi-conical plates 122. The side plates 1132 are bendable to accommodate the curvature of the semi-conical plates 122.

[0043] As a feasible implementation method, combined with Figures 1 to 3 As shown, the side plate 1132 includes three second straight plates 11321 connected to the top of the semi-conical plate 122. The three second straight plates 11321 are connected sequentially, and adjacent second straight plates 11321 form an included angle to adapt to the top shape of the semi-conical plate 122, facilitating the connection between the side plate 1132 and the top of the semi-conical plate 122. The second straight plates 11321 at the edge are connected to the first straight plate 1131, so that the first housing 113 adopts an octagonal structure. When the drive section 21 is rotatably positioned at the connection position between the semi-conical plate 122 and the receiving section 11, a portion of the mounting holes for installing the drive section 21 are located on the second straight plate 11321 in the middle. That is, a portion of the mechanical seal connecting seat 13 described below is installed on the second straight plate 11321. At this time, the height of the second straight plate 11321 should be greater than the radius of the mechanical seal connecting seat 13 to facilitate installation and manufacturing. In addition, the installation position of the silo body 1 in this application can be determined according to the specific circumstances. When used in an old renovation project, the height of the silo body 1 and the position of the feed inlet 112 are determined by the cutting position at the bottom of the raw coal silo.

[0044] The second housing 114 includes two first inverted trapezoidal plates 1141 and two second inverted trapezoidal plates 1142 arranged opposite to each other. The first inverted trapezoidal plates 1141 and the second inverted trapezoidal plates 1142 are connected by triangular plates 1143. The bottom ends of the two first inverted trapezoidal plates 1141 are connected to the top plate of the first straight plate 1131, and the two second inverted trapezoidal plates 1142 are connected to the top of the second straight plate 11321 located in the middle. Multiple triangular plates 1143 are respectively connected to the tops of the remaining multiple second straight plates 11321. The tops of the two first inverted trapezoidal plates 1141 and the two second inverted trapezoidal plates 1142 are extended outward and connected to the first flange 115. This design increases the size of the feed inlet 112, making it easier to receive materials, and also allows the second housing 114 to form a sloping surface, facilitating the entry of materials.

[0045] The discharge port 124 is connected to a discharge pipe 125, and the bottom of the discharge pipe 125 is provided with a second flange 126 for connecting to the output pipe. By setting the discharge pipe 125, the second flange 126 can be supported in a designated position, which facilitates the connection between the second flange 126 and the output pipe, and the way the second flange 126 is set can increase the firmness and sealing of the connection between components.

[0046] Combination Figure 2 and Figure 3 As shown, a pushing screw 23 is provided on the outer periphery of the end of the drive section 21 facing the second cavity 123. The pushing screw 23 is configured to push material towards the second cavity 123 during rotation. Specifically, the drive section 21 is rotatably mounted on the inner wall of the hopper 1 via a bearing. Correspondingly, a mechanical seal connecting seat 13 is provided on the side wall of the hopper 1 to increase the sealing effect at the connection. A through hole is provided in the middle of the mechanical seal connecting seat 13. The drive section 21 has a columnar structure and passes through the through hole. The end of the drive section 21 away from the second cavity 123 is connected to the inner wall of the through hole via a bearing. A pushing screw 23 is provided on the outer periphery of the section of the drive section 21 near the second cavity 123, and the pushing screw 23 is separated from the bearing by a sealing gasket. In this design, when the material tends to move away from the second cavity 123 towards the through hole, the material will first enter the pusher screw 23 and be driven to rotate by the drive section 21, so that the pusher screw 23 can push the material towards the second cavity 123, preventing the material from escaping from the chamber 1. At the same time, it prevents the material from clogging the through hole, ensures the rotation effect of the drive section 21, and reduces the failure rate of the device.

[0047] The storage and activation chamber for bulk materials provided by this invention has a first flange 115 at the top of the chamber body 1 connected to the input pipe, and a second flange 126 at the bottom of the chamber body 1 connected to the output pipe. Bulk materials enter the chamber body 1 through the upper raw coal silo, the gate, and the input pipe, instantly filling the silo. When the humidity is high or the material viscosity is high, it will accumulate on the sides, gradually forming bridging inside, affecting the material's descent. The chamber body 1 has a material-pushing rod 2 body installed on each of the left and right sides. When the material-pushing rod 2 body rotates 360 degrees, it removes the accumulated material on the semi-cylindrical plate 121 and the semi-conical plate 122, allowing it to enter the discharge port 124. It also breaks the possibility of bridging within the first cavity 111, activating the material and allowing it to enter the next stage in an orderly manner.

[0048] This design of the storage and activation chamber is simple to operate and maintain, has a low failure rate, and is highly reliable. Installed at the bottom of the raw coal bunker, it effectively alleviates blockages, and the inlet size can be customized according to the cross-sectional dimensions of the raw coal bunker at the installation location.
