Description

[0001] This application is a divisional application of the invention patent application CN202310452813.3 entitled Solid Particle Material Delivery System, with the parent application filed on April 24, 2023. Technical Field

[0002] This invention relates to the field of material distribution technology, and in particular to a solid particulate material distribution system. Background Technology

[0003] Traditional solid particulate material delivery systems, such as coal-fired material delivery systems, include at least two material delivery units. Each material delivery unit includes a hopper and a feeder located below the hopper. The hopper of one material delivery unit is configured to supply material not only to its own feeder but also to the feeders of adjacent material delivery units. To this end, a material diversion system is provided between the one material delivery unit and the adjacent material delivery unit. This system includes a diversion hopper, a diversion feeder, and a diversion pipe. One end of the diversion hopper is connected to the hopper of the one material delivery unit, and the other end is connected to the inlet of the diversion feeder. The outlet of the diversion feeder is connected to the feeder of the adjacent material delivery unit via the diversion pipe, thereby enabling the diversion and delivery of material from the hopper of one material delivery unit to the feeder of the adjacent material delivery unit.

[0004] In some cases, the diversion pipes of the diversion system are connected to the pipes of adjacent material distribution devices, linking the feeder inlet to the corresponding silo. In this situation, when a material distribution device feeds its own feeder alone, the supplied material may accumulate at the outlet of the diversion pipe, especially in humid and rainy areas and when the material is low-quality coal. This accumulated material may agglomerate and adhere to the pipe wall due to cohesion, causing blockage and disrupting material delivery. Therefore, there is a need in the industry for solid particulate material delivery systems with further improved material conveying performance. Summary of the Invention

Detailed Implementation

[0018] The solid particulate material delivery system of the present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present invention are merely illustrative and are intended to explain the principles of the invention rather than limit it.

[0019] First see Figure 1 and Figure 2 The diagram illustrates the overall structure of a solid particulate material delivery system according to a first embodiment of the present invention, wherein the solid particulate material includes, but is not limited to, coal. Figure 1 and Figure 2 As shown, the solid particulate material delivery system includes a first material delivery device 100 and a second material delivery device 200 arranged adjacent to each other. Each material delivery device includes a hopper 1 and a feeder 2 respectively arranged below the hopper 1.

[0020] The silo 1 is generally tubular in shape, including the silo body 3 located at the top (see [link]). Figure 13 The hopper body 3 is cylindrical, and the discharge hopper 4 is conical, with the diameter gradually decreasing from top to bottom, and the discharge port at the bottom.

[0021] The feeder 2 is located below the corresponding silo and is used to receive materials delivered from the silo. The feeder weighs the received material and conveys it to downstream devices such as grinding mills. The feeder includes an inlet 5 and an outlet 6. Material from the silo is fed into the feeder through the inlet 5, and the feeder conveys the received material to the downstream device through the outlet 6. The feeder can be a traditional belt conveyor or scraper conveyor, the structure of which is well known to those skilled in the art, and its description is omitted here.

[0022] A gate 7 is installed on the channel connecting the hopper and the feeder to control the opening and closing of the channel. When the channel is open, the hopper supplies material to the feeder; when the channel is closed, the hopper stops supplying material. The gate can be a conventional gate, the structure of which is well known to those skilled in the art, and its description is omitted here.

[0023] To prevent material from clogging the feeding channel during the feeding process from the hopper to the feeder, as a preferred solution, a material guiding device 8 can be installed on the channel connecting the hopper and the feeder, such as a traditional vibrating guiding device and / or an insertion guiding device. Figure 1 and Figure 2The diagram illustrates two vibrating flow guiding devices, radially opposite each other and positioned between the gate 7 and the feeder inlet. Preferably, the vibrating flow guiding devices are positioned perpendicular to the channel wall connecting the hopper and the feeder to improve the vibration and unblocking effect. It should be noted that the type, location, and quantity of material guiding devices are not particularly limited and can be flexibly selected based on specific applications and material types. Furthermore, vibrating flow guiding devices and / or insertion flow guiding devices can also be installed on the hopper 4 of the hopper.

[0024] According to the technical solution of the present invention, at least one material distribution device is designed to supply material to the feeders of adjacent material distribution devices, in addition to feeding its own feeder. See also... Figure 1 and Figure 2 ,exist Figure 1 and Figure 2 In the illustrated embodiment, the first material delivery device 100 is designed to supply material to the feeder of the second material delivery device 200. For this purpose, a material diversion system 9 is provided between the first material delivery device 100 and the second material delivery device 200. The material diversion system 9 includes a diversion hopper 10, a diversion feeder 11, and a diversion pipe 12.

[0025] The diversion hopper 10 includes an upper hopper connection portion 13 and a lower diversion discharge hopper 14. The diameter of the diversion discharge hopper 14 gradually decreases from top to bottom, and the lower end is the discharge port. The diversion hopper 10 is connected to the hopper 1 via the hopper connection portion 13. In the illustrated embodiment, the hopper connection portion 13 is connected to the side wall of the discharge hopper 4 of the hopper 1, thereby enabling communication between the diversion hopper and the discharge hopper 4 of the hopper. A feed port 20 is formed between the diversion hopper 10 and the discharge hopper 4 of the hopper. Please refer to [link to relevant documentation]. Figure 10 and Figure 12 As an alternative, the hopper connection part 13 can also be connected to the hopper body 3.

[0026] The diversion feeder 11 is located below the diversion hopper 10 and is used to receive the material delivered by the diversion hopper 10. The diversion feeder weighs the received material and conveys it through the diversion pipe 12 to the diversion inlet 17 of the feeder of the second material delivery device 200. The diversion feeder includes an inlet 15 and an outlet 16. The material from the diversion hopper 10 is input into the diversion feeder through the inlet 15. The diversion feeder conveys the received material through the outlet 16 into the diversion pipe 12, and then delivers the material through the diversion pipe 12 to the diversion inlet 17 of the feeder of the second material delivery device 200. The diversion feeder can be a traditional belt conveyor or scraper conveyor, etc., the structure of which is well known to those skilled in the art, and its description is omitted here.

[0027] A gate 18 is installed on the connecting channel between the diversion hopper 10 and the diversion feeder to control the opening and closing of the connecting channel.

[0028] To prevent material from clogging the feeding channel during the feeding of material from the diversion hopper 10 to the diversion feeder, as a preferred solution, a material guiding device, such as a traditional vibrating guiding device or an insertion guiding device, can be installed on the feeding channel between the gate 18 and the diversion feeder and / or on the side wall of the diversion hopper 10. Figure 1 , Figure 2 and Figure 3 In the illustrated embodiment, two vibrating guide devices 21 and two inserting guide devices 22 are provided on the feeding channel between the gate 18 and the diversion feeder. The two vibrating guide devices are radially opposite each other, and the two inserting guide devices are also radially opposite each other. Adjacent vibrating and inserting guide devices are circumferentially spaced approximately 90 degrees apart and are at roughly the same height. The diversion discharge hopper 14 of the diversion hopper 10 is provided with two sets of vibrating guide devices, each set radially opposite each other. As a preferred embodiment, the vibrating guide devices are positioned perpendicular to the feeding channel or the side wall of the diversion hopper 10, while the inserting guide devices are positioned at an acute angle to the material flow direction. It should be noted that the type, location, and number of material guide devices are not particularly limited and can be flexibly selected based on specific applications and material types.

[0029] See next Figures 2-5 Material discharged from the diversion feeder 11 is fed into the feeder 2 via the diversion inlet 17 of the feeder 2 of the second material delivery device 200, and then discharged directly from the feeder's outlet 6. The feeder's conveyor, such as the belt conveyor described above, has its outlet end adjacent to the outlet 6 and located near the diversion inlet 17 of the feeder 2. Figure 4 and Figure 5 As shown. Therefore, the falling material will hit the conveyor belt at the discharge end of the belt conveyor, causing damage to the conveyor belt. To prevent this from happening, a guide plate 19 is provided at the discharge end of the feeder conveyor of the second material distribution device 200. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 The guide vane 19 is configured to rotate about an axis 23 extending substantially perpendicular to the material feeding direction of the feeder, and can be positioned in two positions: When the diversion feeder is working, the guide plate is in the guiding position (or protective position). In this guiding position, the guide plate 19 blocks the feeder conveyor belt to provide protection, preventing falling material from hitting the feeder conveyor belt. Simultaneously, it guides the material fed in from the diversion inlet 17. Figure 4 As shown; When the feeder of the second material distribution device 200 is working, the guide plate is in a non-guided position. In this non-guided position, the feeder of the second material distribution device 200 operates normally, and the guide plate does not affect the material conveying. Figure 5 As shown.

[0030] The deflector 19 can be in the form of a bent plate, an arc plate, a flat plate, or other forms. Its specific structure is not particularly limited, as long as it can achieve the expected function.

[0031] See also Figure 4 and Figure 5 The illustration shows a specific configuration of the guide vane and its drive mechanism. For example... Figure 4 and Figure 5 As shown, the guide plate's rotating shaft 23 is rotatably mounted on the housing of the feeder of the second material delivery device 200. The guide plate 19 is fixedly connected to the rotating shaft 23 and rotates together with it. One axial end of the rotating shaft 23 is fixedly connected to the drive connecting rod 24, which forms an elongated groove 25 extending along its length. A pin is provided at the end of the drive rod 26 adjacent to the drive connecting rod, and one end of the drive rod is inserted into the elongated groove through the pin and connected to the drive connecting rod 24. The drive device 27 can be a pneumatic drive device, a hydraulic drive device, or an electric drive device, and is used to make the drive rod 26 move linearly, thereby realizing the rotation of the guide plate and positioning it in the guiding position or non-guiding position. Figure 4 This shows the deflector 19 in the deflecting position, while Figure 5 The guide vane 19 is shown in the non-guided position.

[0032] Figure 6 and Figure 7 Another embodiment of the deflector drive mechanism is illustrated. For example... Figure 6 and Figure 7 As shown, the guide plate 19 is rotatably mounted on the housing of the feeder of the second material distribution device 200 via a rotating shaft 23. The guide plate is fixedly connected to the rotating shaft and rotates together with it. A driven gear 28 is provided at one axial end of the rotating shaft. The driving device is a motor 29, which is fixedly mounted on the housing of the feeder of the second material distribution device 200 via a mounting base. The output end of the motor is connected to a reduction mechanism 30, and a driving gear 31 that meshes with the driven gear is provided on the shaft end of the reduction mechanism's output shaft. Thus, the guide plate 19 can rotate in two directions by the forward and reverse rotation of the motor, allowing the guide plate to be in a guiding position or a non-guiding position. Figure 6 This shows the deflector in the flow guiding position, while Figure 7 This shows the deflector in a non-draining position.

[0033] Figure 8 and Figure 9 Another embodiment of the deflector and its drive mechanism is illustrated. (As shown) Figure 8 and Figure 9 As shown, according to this embodiment, the guide plate 119 is linearly movable up and down on the housing 120 of the feeder 2 of the second material delivery device 200. The housing 120 has a slot located near the discharge end of the feeder conveyor and leading to the inner cavity of the feeder. The guide plate 119 is disposed in the slot and moves up and down under the drive of the drive mechanism. In the illustrated embodiment, the drive mechanism includes an electro-hydraulic drive device 121, which is mounted on the housing 120 of the feeder 2 and drives the drive rod 126 to move linearly. The drive rod 126 is connected to the guide plate 119. The guide plate 119 has a connecting portion 125 extending outward from the main body of the guide plate 119. The end of the drive rod 126 facing away from the electro-hydraulic drive device is hinged to the connecting portion 125. In the illustrated embodiment, as... Figure 9 As shown, a drive mechanism is provided on each side of the feeder housing 120. In addition to using an electro-hydraulic drive device as the drive device, the drive mechanism can also use a pneumatic drive device, a hydraulic drive device, an electric drive device, etc., to make the drive rod 126 move linearly, thereby realizing the linear movement of the guide plate and positioning it in the guide position or the non-guide position. Figure 8 This shows that the deflector 119 is in a non-diffusing position, while Figure 9 The guide vane 119 is shown in the guide vane position.

[0034] For maintenance of the deflector, such as Figures 4-9 As shown, an opening 32 is provided at the axial end of the feeder of the second material delivery device 200 adjacent to the discharge port 6, and this opening is closed by a door 33. When maintenance of the guide plate is required, the shaft can be pulled out, and the guide plate can be removed from the feeder opening 32.

[0035] As a preferred option, such as Figure 2 and Figure 3 As shown, a gate 36 can be installed on the connecting channel between the discharge port 16 of the diversion feeder 11 and the diversion inlet 17 of the feeder 2 of the second material delivery device 200 to control the opening and closing of the connecting channel. Additionally, a material guiding device, such as a conventional vibrating guiding device or an insertion guiding device, can be installed on the connecting channel between the discharge port 16 of the diversion feeder 11 and the diversion inlet 17 of the feeder 2 of the second material delivery device 200. Figure 2 The diagram shows two vibrating flow guiding devices 77, which are radially opposite each other and positioned between the gate 36 and the diversion inlet 17 of the feeder 2 of the second material delivery device 200.

[0036] As a preferred embodiment, a rotating flow aid device can be installed at the inlet port 20 formed between the diversion hopper 10 and the discharge hopper 4 of the silo to promote the flow of material from the silo to the diversion hopper 10. Please refer to [link to relevant documentation]. Figure 10 and Figure 11 The rotating flow aid device includes a rotating shaft 37 extending across the feed port 20 and a motor 38 for driving the rotating shaft to rotate. The rotating shaft is rotatably mounted on the cylinder wall of the hopper connection portion 13 of the diversion hopper 10 via its two ends. The output shaft of the motor is connected to a reduction mechanism 39, and the output shaft of the reduction mechanism is connected to the rotating shaft 37. A material-pushing component is provided on the rotating shaft. In the illustrated embodiment, the material-pushing component is in the form of a material-pushing plate. Two sets of axially spaced material-pushing plates 40 are provided on the rotating shaft, each set including four material-pushing plates. During operation, the material-pushing plates rotate with the rotating shaft, which can promote the flow of material from the hopper to the diversion hopper 10 and prevent material blockage. As a preferred embodiment, the root of the material-pushing plate is fixedly connected to a sleeve 46, and the sleeve 46 is detachably fixedly fitted onto the rotating shaft 37, thereby facilitating the replacement of the material-pushing plates. It should be noted that the number of groups of material feed plates and the quantity of each group of material feed plates can be set as needed; other forms of material feed plate structure can also be selected; and each group of material feed plates can be equipped with a separate sleeve, so that a certain group of material feed plates can be replaced individually.

[0037] Figure 12 The illustration shows another preferred embodiment of the rotating flow aid device, which is similar to... Figure 10 and Figure 11 The difference in the illustrated embodiment is that the feeding member is in the form of feeding teeth. Figure 12 In the illustrated embodiment, the rotating shaft 37 is provided with four feeding teeth 41. The four feeding teeth 41 are conical and arranged at intervals from each other along a spiral line centered on the axis of the rotating shaft 37. Figure 12 In the illustrated embodiment, the feeding tooth 41 is divided into a head and a root, with a cross-sectional shape of a quadrangular rhombus. The root is fixedly connected to the sleeve 47, which is detachably fitted and fixed on the rotating shaft, thereby allowing for the replacement of individual feeding teeth. It should be noted that the number of feeding teeth is not limited to a specific number, but can be set according to needs. The specific structural form of the feeding teeth can also be other forms, such as an arbitrary polygonal or circular cross-section. The arrangement of the feeding teeth can also adopt other arbitrary forms, such as multiple rows of feeding teeth spaced apart circumferentially. The rows of feeding teeth can also be arranged axially along the rotating shaft 37. Furthermore, the heights of the feeding teeth can be the same or different; for example, in the case of multiple rows of feeding teeth, the heights of adjacent rows of feeding teeth are different.

[0038] In addition, it should be noted that the material feeding component of the rotary flow aid device is not limited to feeding plates and feeding teeth, but can adopt any other structural form of feeding component, as long as it can promote the flow of material from the hopper to the diversion hopper 10.

[0039] In the technical solutions described above, a material distribution device is designed to supply material to its own feeder and also to the feeders of adjacent material distribution devices through a material diversion system. This invention is not limited to this; alternatively, a material distribution device can be designed to supply material to its own feeder and also to the feeders of adjacent material distribution devices through a material diversion system. Simultaneously, the adjacent material distribution device is designed to supply material to its own feeder and also to the feeder of the first material distribution device through another material diversion system. Both material diversion systems can be the material diversion systems described above in conjunction with the accompanying drawings. This achieves cross-diversion feeding between one material distribution device and another. Furthermore, in the technical solution for cross-diversion feeding between two material distribution devices, the two material distribution devices can share a single diversion feeder. In this case, the diversion feeder must be a bidirectional moving diversion feeder.

[0040] The operation of the solid particulate material distribution system of the present invention will be described below using solid particulate material as coal and its application in a coal-fired power plant as an example. It is assumed that the first material distribution device 100 stores high-calorific-value, high-quality coal, and the second material distribution device 200 stores low-calorific-value, low-quality coal. The technical solution of the first embodiment enables the second material distribution device 200 to obtain high-quality coal from the first material distribution device 100 during peak electricity consumption periods. Therefore, the second material distribution device 200 can switch operating modes between peak and off-peak electricity consumption periods. That is, during off-peak electricity consumption periods, the second material distribution device 200 uses its own feeder to transport coal to the corresponding generating unit to maintain the operation of that unit; when there is a peak electricity consumption period and it is necessary to increase power generation, the first material distribution device 100 can supply high-quality coal to the generating unit to improve the generating capacity of the unit and increase the power supply to the grid to stabilize the normal operation of the grid.

[0041] By employing a cross-feeding technology between two material distribution devices, it is possible to achieve cross-feeding of high-quality coal and low-quality coal to adapt to different power generation conditions.

[0042] The following is a reference to the appendix. Figure 13 -Appendix Figure 15 The solid particulate material delivery system of the second embodiment of the present invention is described below. The main structure of the material delivery system of the second embodiment of the present invention is basically the same as that of the first embodiment. Therefore, the same components are indicated by the same reference numerals and their descriptions are omitted. The differences between the two are described below.

[0043] Similar to the first embodiment, according to the technical solution of the second embodiment of the present invention, at least one material distribution device is designed to supply material to the feeders of adjacent material distribution devices in addition to supplying material to its own feeder. See also... Figures 13-15 In the second embodiment, the second material delivery device 200 is designed to supply materials to the feeder of the first material delivery device 100. Therefore, a material diversion system 49 is provided between the second material delivery device 200 and the first material delivery device 100. The difference between the material delivery system of the second embodiment and that of the first embodiment lies in the material diversion system. The following description focuses solely on the material diversion system of the second embodiment.

[0044] The material diversion system 49 includes a diversion hopper 110, a diversion feeder 111, and a diversion pipe 112. The diversion hopper 110 has the same structure as the diversion hopper 10 in the first embodiment, and its description is omitted here for the sake of simplicity.

[0045] The diversion hopper 110 is connected to the hopper 1 of the second material distribution device 200. The diversion feeder 111 is located below the diversion hopper 110 and is used to receive the material distributed by the diversion hopper 110. The diversion feeder 111 transports the material to the feeder of the first material distribution device 100 via the diversion pipe 112. The diversion feeder includes an inlet 15 and an outlet 16. One end of the diversion pipe 112 is connected to the outlet 16 of the diversion feeder 111, and the other end is connected to the inlet of the feeder 2 of the first material distribution device 100 and the channel 50 of the corresponding hopper. Material from the diversion hopper 110 is fed into the diversion feeder through the feed inlet 15. The diversion feeder conveys the received material into the diversion pipe 112 through the discharge outlet 16, and then sends the material to the channel 50 through the diversion pipe 112. Finally, the material enters the feeder 2 of the first material distribution device 100 through the feed inlet 5 of the feeder of the first material distribution device 100.

[0046] Material guiding devices, such as traditional vibratory guiding devices or insertion guiding devices, can be installed on the diversion pipe 112. Figures 13-15 The diagram shows two vibrating diversion devices 58, which are arranged vertically along the diversion pipe 112.

[0047] In the second embodiment, the second material delivery device 200 uses the material diversion system 49 to feed the material into the feeder 2 of the first material delivery device 100 via the feed inlet 5 of the feeder of the first material delivery device 100. In this case, the diversion feeder can omit the weighing function.

[0048] In the technical solutions described above, a material distribution device is designed to supply material to its own feeder and also to the feeders of adjacent material distribution devices through a material diversion system. This invention is not limited to this; alternatively, a material distribution device can be designed to supply material to its own feeder and also to the feeders of adjacent material distribution devices through a material diversion system. Simultaneously, the adjacent material distribution device is designed to supply material to its own feeder and also to the feeder of the first material distribution device through another material diversion system. Both material diversion systems can be the material diversion systems described above in conjunction with the accompanying drawings. This achieves cross-feeding between one material distribution device and another. Furthermore, in the technical solution for cross-diversion feeding between two material distribution devices, the two material distribution devices can share a single diversion feeder. In this case, the diversion feeder must be a bidirectional moving diversion feeder.

[0049] Using the technical solution of the second embodiment, the material distribution device 100 can realize three different feeding methods: material distribution device 100 feeding alone, material distribution device 200 feeding alone, and material distribution device 100 and material distribution device 200 feeding together. When material distribution device 100 and material distribution device 200 each store different types of materials, material distribution device 100 can feed the first type of material, material distribution device 200 can feed the second type of material, and it can also feed a mixture of the first and second types of materials, thereby adapting to different needs.

[0050] In the above-described technical solution of the second embodiment, the diversion pipe 112 is connected to the channel 50 of the first material distribution device 100, which connects the feed inlet of the feeder 2 and the corresponding silo. For example, if the material distribution device 100 supplies material alone, the supplied material may accumulate at the port of the diversion pipe 112 connected to the channel 50. This is especially problematic in humid and rainy areas or when the material is low-quality coal. This accumulated material may clump together and adhere to the pipe wall due to cohesion, causing blockage of the diversion pipe 112. Therefore, as a preferred technical solution, a gate can be installed at the outlet port of the diversion pipe 112 to prevent such situations from occurring.

[0051] Please see Figures 16-18 ,in Figure 16 It is similar to Figure 13 The perspective view illustrates a solid particulate material delivery system with gates installed on the diversion pipeline; Figure 17 This is a partially enlarged perspective view illustrating the gate's drive mechanism; and Figure 18This is a partial enlarged perspective view, in which the feed channel of the feeder of the first material delivery device has been removed to clearly show the diversion pipe gate and its drive device 156. (See attached image.) Figures 16-18 As shown, the rotating shaft 137 of the diversion pipe gate 150 is rotatably mounted on the pipe wall of the diversion pipe 112. The diversion pipe gate 150 is fixedly connected to the rotating shaft 137 and rotates together with it. One axial end of the rotating shaft 137 is fixedly connected to the drive connecting rod 151, and the drive connecting rod forms an elongated groove 152 extending along the length of the rod. A pin 155 is provided at the end of the drive rod 153 adjacent to the drive connecting rod. The drive rod is inserted into the elongated groove through the pin 155 and connected to the drive connecting rod 151. The drive device 156 can be an electro-hydraulic drive device, a pneumatic drive device, a hydraulic drive device, or an electric drive device. The one shown in the figure is an electro-hydraulic drive device, which is used to make the drive rod 153 move linearly and extend and retract, thereby realizing the rotation of the diversion pipe gate and positioning it in the open or closed position. Figure 18 The diversion pipe gate 150 is shown in the open position.

[0052] By setting the diversion pipe gate 150, when the material delivery device 100 supplies material alone, the diversion pipe gate 150 is in the closed position, blocking the discharge port of the diversion pipe 112, thereby preventing the supplied material from accumulating at the port of the diversion pipe 112 that connects to the channel 50 and preventing blockage of the diversion pipe. When the material delivery device 200 supplies material alone or when the material delivery devices 100 and 200 supply material together, the diversion pipe gate 150 is in the open state.

[0053] The drive unit that rotates the diversion pipe gate 150 can also be a combination Figure 6 and Figure 7 For the sake of brevity, the description of the drive device employing a gear transmission mechanism is omitted here.

[0054] Figures 18A-18E Another embodiment of the diversion pipe gate is illustrated, wherein Figure 18A This is a partial perspective view, illustrating the overall structure of the diversion pipe gate and its drive device; Figure 18B It is a partial perspective view in which the diversion pipe and gate support housing have been removed to clearly show the configuration structure of the diversion pipe gate, drive unit and feed port of the channel connecting the feeder inlet and the corresponding hopper; Figure 18C This is a perspective view of the diversion pipe gate and its drive device; Figure 18D This is a partial perspective view where the drive unit and diversion pipe gate have been removed to clearly show the configuration of the diversion pipe, gate support housing, and the channel connecting the feeder inlet to the corresponding hopper; and Figure 18E This is a partial perspective view, illustrating the internal structure of the gate support box.

[0055] Please see Figures 18A-18E The diversion gate 201 is an arc-shaped plate that fits against the outer wall of the channel 50 connecting the feeder inlet and the corresponding hopper during use, and moves up and down along the outer wall between the open and closed positions. In the closed position, the diversion gate 201 closes the feed port 209 of the channel 50 (see [link]). Figure 18B In the open position, the diversion pipe gate 201 opens the feed port 209 of the channel 50, thereby connecting the discharge port of the diversion pipe 112 with the feed port 209 of the channel 50.

[0056] Please see Figure 18E The support housing 203 has a through hole 210 with a shape substantially the same as the feed port 209 of the channel 50. In the installed state, the through hole 210 is aligned with the feed port 209 of the channel 50. Figure 18A As shown, the discharge port of the diversion pipe 112 is connected to the through hole 210 formed on the support box 203.

[0057] See next Figures 18A-18C The drive device 202 is used to drive the diversion pipe gate 201 to move up and down. In the illustrated embodiment, a drive device 202 is provided on each side of the diversion pipe gate 201. The drive device can be an electro-hydraulic drive device, a pneumatic drive device, a hydraulic drive device, or an electric drive device such as a linear motor. The drive device can be mounted on the feeder 2 housing via a bracket, or mounted on the outer wall of the channel 50 via a bracket. The drive device 202 is used to drive the drive rod 204 to move linearly. The end of the drive rod 204 opposite to the drive device 202 is connected to the diversion pipe gate 201. 18A- Figure 18C The diagram illustrates a preferred connection method. Each side of the diversion gate 201 is provided with a connecting rod 205 extending away from each other, with a connecting hole formed at the outer end of each connecting rod 205. The end of the drive rod 204 is provided with a connecting fork 211, including two opposing and spaced-apart connecting plates 212, each with opposing connecting holes. Thus, a hinged connection is achieved between the drive rod 204 and the diversion gate 201 via a pin 206.

[0058] Please see Figure 18EThe support box 203 is roughly box-shaped, forming an arc-shaped groove extending vertically. Side edges 215 are formed on both sides of the arc-shaped groove, and an arc-shaped flange 208 is provided at the bottom edge of the arc-shaped groove. The diameter of the arc-shaped flange 208 is the same as the diameter of the channel 50. In the installed state, the support box 203 is mounted on the channel 50 with the side containing the arc-shaped groove. The feed port 209 of the channel 50 is aligned with the through hole 210 on the support box 203. The side edges 215 and the arc-shaped flange 208 of the support box abut against the outer wall of the channel 50, thereby defining an arc-shaped space between the support box and the outer wall of the channel 50. This space has the same shape as the diversion pipe gate 201 but is slightly larger in size. The top of this space is open to form an insertion port 207, and the bottom of this space is defined by the arc-shaped flange 208 at the bottom of the arc-shaped groove. As a preferred embodiment, the arc-shaped flange can support the diversion pipe gate inserted through the insertion port. The support box can be fixed to the channel 50, for example, by welding. Alternatively, the support box may not form an arcuate flange 208. Instead, an annular support ring can be provided on the outer wall of the channel 50. In the assembled state, the bottom of the support box abuts against the support ring and is connected to it, for example, by welding.

[0059] During operation, when material is supplied solely by material delivery device 100, the diversion pipe gate 201 is in the closed position, blocking the outlet port of diversion pipe 112, thereby preventing the supplied material from accumulating at the port of diversion pipe 112 connected to channel 50 and preventing blockage of the diversion pipe. When material is supplied solely by material delivery device 200 or jointly by material delivery devices 100 and 200, the diversion pipe gate 201 is in the open state.

[0060] See next Figure 19 and Figure 20 , Figure 19 and Figure 20 The figure illustrates the overall structure of a solid particulate material delivery system according to a third embodiment of the present invention. The main structure of the material delivery system of the third embodiment is substantially the same as that of the first and second embodiments; therefore, components identical to those in the first and second embodiments are indicated by the same reference numerals and their descriptions are omitted. The differences between the third embodiment and the first and second embodiments will be described below only.

[0061] According to the technical solution of the third embodiment of the present invention, two material diversion systems are provided between the first material delivery device 100 and the second material delivery device 200: a first material diversion system 59 and a second material diversion system 69. The first material delivery device 100 delivers materials to the feeder 2 of the second material delivery device 200 via the first material diversion system 59; the second material delivery device 200 distributes materials to the feeder 2 of the first material delivery device 100 via the second material diversion system 69. The first material diversion system 59 is the same as the material diversion system 9 of the first embodiment, and the second material diversion system 69 is the same as the material diversion system 49 of the second embodiment, therefore, the corresponding description is omitted here.

[0062] In the embodiments shown above, the material diversion system uses a diversion hopper and a diversion feeder to divert material from the hopper of one material distribution device to the feeder of another material distribution device. However, the diversion feeder can also be omitted, and a connecting pipe can be used to connect the diversion hopper and the diversion inlet 17 of the feeder of another material distribution device 200 (see...). Figure 3 ) or another material delivery device 100, the passage 50 connecting the feed inlet of the feeder 2 and the corresponding hopper (see Figure 15 In this configuration, the diversion hopper and the connecting pipe are inclined, with the feed inlet of the diversion hopper located at the top and the discharge outlet of the connecting pipe located at the bottom. A gate valve and a flow guiding device can be installed on the connecting pipe.

[0063] Furthermore, in the above embodiments, the feed inlet 17 of the feeder of one material distribution device to the feeder of another material distribution device (see...) Figure 3 ) or channel 50 (see Figure 15 The invention is not limited to the diversion and distribution of materials. Other material inlets can also be set on the feeder of the other material distribution device to receive the diverted and distributed materials, so that the hopper of one material distribution device diverts and distributes materials to the feeder of another material distribution device through the other material inlet.

[0064] The present invention has been described above with reference to the accompanying drawings and specific embodiments, but this is merely for illustrative purposes, and the present invention is not limited thereto. Therefore, it will be apparent to those skilled in the art that various changes and modifications can be made within the technical spirit and scope of the present invention, and these changes and modifications should also be understood to fall within the scope of the present invention, which is defined by the claimed technical solutions and their equivalents.
