However, this method generates significant dust and pollution during the silica's descent, and the silica is also prone to breakage during the fall, resulting in a high breakage rate.

The first transmission belt is used to transfer silica in the first transfer station to the second transfer station. The second transmission belt is disposed in a third transfer station. The second transmission assembly includes a buffer silo, a feeder, and a discharge feeder. The buffer silo is a vertically arranged enclosed silo with a feed inlet at the top and a discharge outlet at the bottom. The feeder and discharge feeder are located at the feed inlet and discharge outlet, respectively. The feeder is located in the second transfer station and is used to transport silica from the second transfer station to the buffer silo through the feed inlet. The discharge feeder is located in the second transfer station and is used to transport silica from the buffer silo to the second conveyor belt in the third transfer station through the discharge outlet.

[0005] In one embodiment, the buffer chamber includes an inlet pipe and an outlet pipe. The top of the inlet pipe forms an inlet port, the top of the outlet pipe is connected to the bottom of the inlet pipe, and the bottom of the outlet pipe forms an outlet. The outlet pipe is inclined from top to bottom so that the outlet and the inlet are staggered.

[0006] In one embodiment, the discharge pipe is formed by splicing together multiple surrounding plates in sequence along its circumference. One of the surrounding plates forms a buffer wall, which is inclined from top to bottom and is used to receive silica entering the discharge pipe from the bottom of the inlet pipe. A punching plate is provided on the inner side of the buffer wall, which extends along the extension direction of the buffer wall.

[0007] In one embodiment, the ejector plates are stacked on the buffer wall and extend along the extension direction of the buffer wall. The ejector plates are provided with a plurality of ejector ribs, which are spaced apart along the extension direction of the ejector plates.

[0008] In one embodiment, there are multiple discharge pipes, the top of each discharge pipe is connected to the bottom of the inlet pipe, and each discharge pipe has a discharge port at its bottom. The multiple discharge pipes are inclined from top to bottom in different directions, so that the multiple discharge ports are spaced apart.

[0009] In one embodiment, a plurality of reinforcing hoops are fitted around the outer periphery of the feed pipe. The plurality of reinforcing hoops are arranged at vertical intervals. A reinforcing component is provided between any two reinforcing hoops. The reinforcing component includes a plurality of reinforcing ribs arranged at circumferential intervals around the feed pipe. The two ends of each reinforcing rib are respectively connected to the two adjacent reinforcing hoops.

[0010] In one embodiment, a bar valve is provided at the discharge port.

[0011] In one embodiment, the second transfer station is also provided with a discharge pipe. The bottom end of the discharge pipe is connected to the inlet, and the top end of the discharge pipe has a plurality of spaced discharge ports. The feeder is located at the discharge port and is used to discharge silica from the second transfer station into the inlet through the discharge pipe via the plurality of discharge ports.

[0012] In one embodiment, an installation frame is also provided between the second transfer station and the third transfer station, and the unloading pipe and the buffer bin are installed on the installation frame from top to bottom.

[0013] In one embodiment, the mounting frame includes a mounting frame and multiple mounting plates. The mounting frame forms an installation space.

[0014] The technical solution of this utility model involves arranging a first transfer station and a second transfer station horizontally at intervals, and placing a third transfer station below the second transfer station. A first conveyor belt is used to transfer silica from the first transfer station to the second transfer station. A vertically enclosed buffer silo and a feeder at its top inlet feed inlet feed the silica from the second transfer station into the buffer silo. Then, a feeder at the bottom outlet discharges the silica at a low speed and evenly onto the second conveyor belt of the third transfer station. This enclosed buffer silo blocks the silica's falling path from the outside air, confining dust within the buffer silo and reducing dust generation. Simultaneously, the buffer silo reduces the falling speed of the silica, absorbing the impact force in advance, thereby reducing the impact energy on the silica and effectively preventing it from breaking due to large impacts, thus significantly reducing the silica breakage rate.

[0022] In industrial silicon production, silica typically needs to be transported to designated locations, often requiring multiple conveyor belts. Currently, the transfer of silica from one conveyor belt to the next usually involves creating a drop between them, with one end of the first conveyor belt positioned above the other, allowing the silica to fall from the first belt onto the second. However, this method generates significant dust and pollution during the silica's descent, and the silica is also prone to breakage during the fall, resulting in a high breakage rate.

[0023] This utility model proposes a silica transfer device.

[0024] Please see Figures 1 to 4 In one embodiment of this utility model, the silica transfer device 100 includes: The first transfer station 10, the second transfer station 20 and the third transfer station 30 are arranged at intervals along the horizontal direction, and the third transfer station 30 is located below the second transfer station 20. The first transmission component 40 includes a first transmission belt 41, which is disposed between the first transfer station 10 and the second transfer station 20. The first transmission belt 41 is used to transfer silica in the first transfer station 10 to the second transfer station 20. The second transmission belt 42 is disposed in the third transfer station 30. The second transmission component 50 includes a buffer hopper 51, a feeder 52, and a discharge feeder 53. The buffer hopper 51 is a vertically arranged enclosed buffer hopper 51. The top of the buffer hopper 51 has a feed inlet 511, and the bottom of the buffer hopper 51 has a discharge outlet 512. The feeder 52 and the discharge feeder 53 are located at the feed inlet 511 and the discharge outlet 512, respectively. The feeder 52 is located in the second transfer station 20 and is used to transport silica from the second transfer station 20 to the buffer hopper 51 through the feed inlet 511. The discharge feeder 53 is located in the second transfer station 20 and is used to transport silica from the buffer hopper 51 to the second conveyor belt 42 in the third transfer station 30 through the discharge outlet 512.

[0025] The technical solution of this utility model arranges the first transfer station 10 and the second transfer station 20 horizontally at intervals, and places the third transfer station 30 below the second transfer station 20. The first conveyor belt 41 is used to transfer the silica from the first transfer station 10 to the second transfer station 20. The silica in the second transfer station 20 is first fed into the buffer chamber 51 through the vertically enclosed buffer chamber 51 and the feeding feeder 52 at the top inlet 511. Then, the discharging feeder 53 at the bottom outlet 512 discharges the silica to the second conveyor belt 42 of the third transfer station 30 at a low speed and evenly. In this way, the closed buffer chamber 51 blocks the connection between the falling path of the silica and the outside air, so that the dust is confined in the buffer chamber 51, reducing the dust generated by falling. At the same time, the buffer chamber 51 can also reduce the falling speed of the silica and absorb the impact force generated by the falling silica in advance, thereby reducing the impact energy of the silica. This can effectively prevent the silica from breaking due to large impacts, and thus significantly reduce the breakage rate of silica.

[0026] In one embodiment of the present invention, the buffer chamber 51 includes an inlet pipe 513 and an outlet pipe 514. The top end of the inlet pipe 513 forms an inlet port 511, the top end of the outlet pipe 514 is connected to the bottom end of the inlet pipe 513, and the bottom end of the outlet pipe 514 forms an outlet port 512. The outlet pipe 514 is inclined from top to bottom, so that the outlet port 512 and the inlet port 511 are staggered.

[0027] Specifically, the buffer chamber 51 is configured with an inlet pipe 513 and a downward-sloping outlet pipe 514, so that the outlet 512 and the inlet 511 are staggered. After the silica falls from the inlet pipe 513, it must slide along the inclined pipe wall to the outlet 512. During the sliding process, the silica continuously rubs against the pipe wall, and its speed is gradually consumed, so that it enters the discharge feeder 53 at a lower and more stable flow rate, avoiding high-speed impact at the outlet 512. At the same time, the staggered arrangement cuts into the inclined section, which prolongs the movement path of the silica in the closed chamber, so that the remaining impact force is further absorbed by the pipe wall. In this way, while maintaining continuous feeding, dust escape is significantly reduced, and the silica breakage rate is further reduced, achieving a closed, low-dust, and low-loss transfer effect.

[0028] In one embodiment of the present invention, the discharge pipe 514 is formed by splicing together multiple surrounding plates in sequence along its circumference. One of the surrounding plates forms a buffer wall. The buffer wall is inclined from top to bottom and is used to receive silica that enters the discharge pipe 514 from the bottom end of the inlet pipe 513. A punching plate 515 is provided on the inner side of the buffer wall. The punching plate 515 extends along the extension direction of the buffer wall.

[0029] Specifically, a buffer wall inclined from top to bottom is provided inside the discharge pipe 514 so that when the silica falls from the bottom of the feed pipe 513, it first impacts the buffer wall. The impact energy is dispersed by the inclined wall surface and converted into kinetic energy that slides down the wall. The ejector plate 515 added to the inner side of the buffer wall extends along the wall surface. By setting the ejector plate 515, the buffer wall can be reinforced, which can effectively prevent the silica from breaking through the buffer wall, so that the discharge pipe 514 has better reliability and durability.

[0030] In one embodiment of the present invention, the material ejection plate 515 is stacked on the buffer wall and extends along the extension direction of the buffer wall. The material ejection plate 515 is provided with a plurality of material ejection ribs 5151, which are spaced apart along the extension direction of the material ejection plate 515.

[0031] Furthermore, the feeding plate 515 has multiple feeding ribs 5151 protruding at intervals on the side facing the silica. The feeding ribs 5151 are arranged along the extension direction of the plate. When the silica slides down the buffer wall, it first contacts the top of the feeding ribs 5151, and then falls into the groove formed between two adjacent feeding ribs 5151, generating multiple small-amplitude collisions and tumbling, thereby gradually consuming the remaining kinetic energy and further reducing the breakage of the silica, thus reducing the silica breakage rate. At the same time, the feeding ribs 5151 distribute the impact load to each section of the feeding plate 515 and transfer it to the buffer wall through the stacked contact surface, avoiding local stress concentration. This is equivalent to adding transverse reinforcing ribs to the buffer wall, significantly improving its impact resistance and wear resistance, and extending the service life of the buffer wall and the feeding plate 515 simultaneously.

[0032] In one embodiment of this utility model, there are multiple discharge pipes 514, the top of each discharge pipe 514 is connected to the bottom of the inlet pipe 513, and each discharge pipe 514 has a discharge port 512 at its bottom. The multiple discharge pipes 514 are inclined from top to bottom in different directions, so that the multiple discharge ports 512 are spaced apart.

[0033] Specifically, the bottom end of the feed pipe 513 is simultaneously connected to multiple discharge pipes 514 with different inclination directions, allowing silica to flow from the feed pipe 513 into each discharge pipe 514. Each discharge pipe 514 retains its buffer wall and impact plate 515 structure. The silica slides and collides along different inclined paths within its respective pipe, decelerating before finally being discharged at low speed from multiple spaced discharge ports 512. By setting multiple discharge pipes 514, the impact of silica on a single discharge pipe 514 can be dispersed across multiple discharge pipes 514, preventing the discharge pipes 514 from being damaged by excessive impact. Furthermore, it can reduce the instantaneous flow rate and impact load of each discharge port 512, thereby reducing dust and silica breakage.

[0034] In one embodiment of the present invention, a plurality of reinforcing hoops 516 are sleeved around the outer periphery of the feed pipe 513. The plurality of reinforcing hoops 516 are arranged at intervals along the vertical direction. A reinforcing component 517 is provided between any two reinforcing hoops 516. The reinforcing component 517 includes a plurality of reinforcing ribs 5171 arranged at intervals around the feed pipe 513 in the circumferential direction. The two ends of each reinforcing rib 5171 are respectively connected to the two adjacent reinforcing hoops 516.

[0035] Furthermore, multiple reinforcing hoops 516 are vertically spaced around the outer periphery of the feed pipe 513, and several reinforcing ribs 5171 are evenly distributed around the feed pipe 513 between adjacent reinforcing hoops 516 to form a grid-like outer skeleton. When the silica falling at high speed generates impact and lateral expansion force inside the pipe, the reinforcing hoops 516 prevent the pipe wall from bulging and deforming through circumferential restraint, and the reinforcing ribs 5171 connect the hoops into a whole, which can effectively avoid damage to the feed pipe 513 caused by local impact, so that the feed pipe 513 has better structural strength, is more durable and reliable.

[0036] In one embodiment of this utility model, a bar valve 518 is provided at the discharge port 512.

[0037] Specifically, a bar valve 518 is installed at the discharge port 512 of the buffer chamber 51. By inserting and removing the bar, the width of the discharge gap can be changed instantly, thereby achieving stepless adjustment of the silica flow rate at the discharge port 512.

[0038] In one embodiment of the present invention, the second transfer station 20 is further provided with a discharge pipe 2170. The bottom end of the discharge pipe 2170 is connected to the inlet 511, and the top end of the discharge pipe 2170 is formed with a plurality of spaced discharge ports 71. The feeder 52 is provided at the discharge port 71. The feeder 52 is used to discharge the silica from the second transfer station 20 into the inlet 511 through the discharge pipe 2170 via the plurality of discharge ports 71.

[0039] Specifically, the second transfer station 20 is equipped with a discharge pipe 2170, the bottom end of which is connected to the inlet 511, and the top end forms multiple spaced discharge ports 71. The feeder 52 is located at the discharge ports 71, and discharges the silica in the second transfer station 20 into the inlet 511 through the discharge ports 71 and the discharge pipe 2170. The simultaneous feeding from multiple discharge ports 71 can improve the efficiency of unloading silica into the buffer silo 51, making it more efficient.

[0040] In one embodiment of this utility model, an installation frame 60 is also provided between the second transfer station 20 and the third transfer station 30, and the unloading pipe 2170 and the buffer chamber 51 are installed on the installation frame 60 from top to bottom.

[0041] Specifically, the unloading pipe 2170 and the buffer chamber 51 are integrated into the same vertically arranged mounting bracket 60. Without additional support, the unloading pipe 2170 and the buffer chamber 51 can be stably installed, saving floor space.

[0042] In one embodiment of this utility model, the mounting frame 60 includes a mounting frame 61 and multiple mounting plates 62. The mounting frame 61 forms an mounting space 64. The multiple mounting plates 62 are arranged vertically at intervals in the mounting space 64. Each mounting plate 62 is arranged horizontally, and the two ends of each mounting plate 62 in the horizontal direction are respectively connected to the two sides of the mounting frame 61 in the horizontal direction. The unloading pipe 2170 and the buffer chamber 51 are connected to at least one mounting plate 62. Multiple reinforcing supports 63 are also connected to the outside of the buffer chamber 51 at intervals in the circumference. Each reinforcing support 63 is installed on the mounting plate 62 connected to the buffer chamber 51.

[0043] Furthermore, the mounting frame 61 is vertically positioned between the second transfer station 20 and the third transfer station 30, forming an installation space 64 inside. Multiple horizontal mounting plates 62 are arranged at intervals along the vertical direction, and their ends are fixed to both sides of the mounting frame 61, forming a multi-layer load-bearing plane. The unloading pipe 2170 and the buffer chamber 51 pass through this space from top to bottom and are respectively fastened to the corresponding mounting plates 62. Multiple reinforcing supports 63 are evenly arranged around the outer periphery of the buffer chamber 51, and each support is fixed to the same mounting plate 62 along the circumference, so that the buffer chamber 51 forms a multi-point rigid connection with the beam, making the buffer chamber 51 more firmly and reliably installed on the mounting frame 60, and the structural reliability is higher.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
