Description

Technical Field

[0001] This utility model relates to the field of buffer bin technology, and in particular to a buffer bin for rapid loading stations. Background Technology

[0002] A rapid loading station is an automated equipment used for efficient and quantitative loading of bulk materials (such as coal, ore, cement, etc.), and is widely used in mines, ports, railways and other scenarios.

[0003] During operation, materials enter the weighing chamber through the buffer chamber at the top of the transfer station. The buffer chamber receives and transfers materials. When the feeding speed at the top of the buffer chamber is greater than the discharge speed at the bottom, materials will accumulate inside the buffer chamber. When the discharge speed is greater than the feeding speed, the materials inside the buffer chamber will be discharged outwards. When materials accumulate inside the buffer chamber, they may adhere to the sloping inner wall near the discharge port, causing material sticking. As time increases, the amount of material accumulated on the inner wall of the buffer chamber will decrease the material output speed, affecting the normal use of the buffer chamber. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when materials accumulate inside the buffer bin, they may adhere to the inclined inner wall of the buffer bin near the discharge port, causing material sticking. As time goes on, the amount of material accumulated on the inner wall of the buffer bin will increase, which will lead to a decrease in the material output speed of the buffer bin and affect the normal use of the buffer bin. Therefore, a buffer bin for a fast loading station is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a buffer bin for a rapid loading station, comprising a support frame and a bin. The support frame is installed on the ground to support the bin and the rapid loading station. The top and bottom of the bin are respectively provided with an inlet and an outlet. A frame rod is fixedly connected to the outer surface of the support frame near the bottom of the bin. A valve plate is slidably connected to the inner wall of the frame rod. A hydraulic rod is provided on the outer surface of the support frame near the frame rod. The output rod of the hydraulic rod is fixedly connected to one end of the valve plate. The bin is equipped with a cleaning device that can clean the inner wall of the bin near the outlet.

[0006] Furthermore, the cleaning device includes a support rod, which is installed at the top of the hopper via a convenient assembly. An electric push rod is provided at the bottom of the support rod. Several T-shaped rods are installed on the output rod of the electric push rod. Two sleeve rods are slidably connected to the end of the T-shaped rod away from the output rod of the electric push rod. A spring is provided inside the sleeve rod. The two ends of the spring are fixedly connected to one side of the inner wall of the sleeve rod and one end of the T-shaped rod, respectively. Scraper rods are fixedly connected to one side of the outer surface of the two sleeve rods. The heights of the scraper rods on the outer surfaces of the two sleeve rods are different. A rotating wheel is rotatably connected to the end of the sleeve rod away from the T-shaped rod. The rotating wheel rolls on the inner wall of the hopper.

[0007] Furthermore, a round rod is fixedly connected to one end of the inner wall of the sleeve rod, and one end of the round rod slides on the inner wall of the end of the T-shaped rod away from the output rod of the electric push rod.

[0008] Furthermore, a reinforcing rod is fixedly connected to the top of the T-shaped rod, and the end of the reinforcing rod away from the top of the T-shaped rod is fixedly connected to one side of the electric push rod output rod.

[0009] Furthermore, a sealing ring is fitted on the outer surface of the electric push rod, and the sealing ring is located outside the connection between the electric push rod power rod and the output rod.

[0010] Furthermore, the convenient component includes two slotted plates, which are respectively fixed to both ends of the support rod. Several bolts are inserted into the inner wall of the slotted plates, and several threaded holes are respectively opened on both sides of the top of the hopper. The outer surface of the bolts is threadedly connected to the inner wall of the threaded holes.

[0011] Furthermore, a number of positioning blocks are fixedly connected to the top of the hopper, with two positioning blocks fixed on the side of the top of the hopper near the threaded hole.

[0012] Furthermore, the edges of the outer surfaces of the two positioning blocks that are close to each other are arc-shaped.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, a cleaning device is installed. By extending or retracting the output rod of the electric push rod, the T-shaped rods are controlled to move downward or upward inside the hopper. A spring is installed inside the sleeve rod so that the end of one T-shaped rod away from the electric push rod and the total length of the two sleeve rods can be adapted to the width of the sloping inner wall of the hopper. The scraper on the outer surface of the sleeve rod is then placed against the inner wall of the hopper to scrape and clean the sloping inner wall of the hopper, thus minimizing the adhesion of material to the inner wall of the hopper near the discharge port and affecting the output rate of the material inside the hopper.

Detailed Implementation

[0021] Example 1, such as Figure 1-3 As shown, the buffer bin for the rapid loading station includes a support pole 1 and a hopper 4. The support pole 1 is installed on the ground to support the hopper 4 and the rapid loading station. The top and bottom of the hopper 4 are respectively provided with an inlet and an outlet. A frame rod 3 is fixedly connected to the outer surface of the support pole 1 near the bottom of the hopper 4. A valve plate 6 is slidably connected to the inner wall of the frame rod 3. A hydraulic rod 5 is provided on the outer surface of the support pole 1 near the frame rod 3. The output rod of the hydraulic rod 5 is fixedly connected to one end of the valve plate 6. The hopper 4 is equipped with a cleaning device 2 that can clean the inner wall of the hopper 4 near the outlet. When using the buffer bin, the material is added into the bin 4 through the feed port at the top of the bin 4. The operation of the hydraulic rod 5 retracts, causing the valve plate 6 to move on the inner wall of the frame rod 3, which can open the discharge port at the bottom of the bin 4. At this time, the material inside the bin 4 can be discharged through the discharge port. When the feeding speed at the top of the bin 4 is greater than the discharge speed at the bottom, the material will accumulate inside the bin 4. When the discharge speed is greater than the feeding speed, the material inside the bin 4 will be discharged outward. The operation of the hydraulic rod 5 extends, causing the valve plate 6 to move to one end and fit against the inner wall of the frame rod 3, which can close the discharge port at the bottom of the bin 4.

[0022] Reference Figure 1-5As shown in this embodiment: the cleaning device 2 includes a support rod 21, which is installed at the top of the hopper 4 via a convenient component 23. An electric push rod 22 is installed at the bottom of the support rod 21. Several T-shaped rods 24 are installed on the output rod of the electric push rod 22. Two sleeve rods 25 are slidably connected to the ends of the T-shaped rods 24 away from the output rod of the electric push rod 22. Springs 26 are installed inside the sleeve rods 25, and the two ends of the springs 26 are fixedly connected to one side of the inner wall of the sleeve rod 25 and one end of the T-shaped rod 24, respectively. Scraper rods 28 are fixedly connected to one side of the outer surface of the two sleeve rods 25, and the heights of the scraper rods 28 on the outer surfaces of the two sleeve rods 25 are different. The sleeve rods 25 are located away from the T-shaped rods 24. One end of the device is rotatably connected to a wheel 27, which rolls on the inner wall of the hopper 4. By setting up a sleeve rod 25, when using the buffer hopper, if the material output speed inside the hopper 4 decreases significantly without external influence, the electric push rod 22 at the bottom of the support rod 21 can be extended. The output rod of the electric push rod 22 pushes each T-shaped rod 24 to move downward inside the hopper 4. The wheel 27 on the outer surface of the two sleeve rods 25 at one end of the T-shaped rod 24 will roll on the inner wall of the hopper 4. The scraper 28 on one side of the two sleeve rods 25 can scrape off the material adhering to the inclined inner wall of the hopper 4. At the same time, during the descent of the T-shaped rod 24, the two sleeve rods 25 on the outer surface are subjected to material. The pressure on the inner wall of bin 4 causes it to slide in the same direction and compress the internal spring 26, making the T-shaped rod 24 away from the output rod of the electric push rod 22. The total length of the two sleeve rods 25 is adapted to the width of the inclined inner wall of bin 4. After the output rod of the electric push rod 22 extends to its maximum distance, the electric push rod 22 is operated to control the output rod of the electric push rod 22 to retract, driving each T-shaped rod 24 to move upward. During the upward movement of the T-shaped rod 24, the compressed spring 26 inside the sleeve rod 25 returns to its original state, pushing the sleeve rod 25 to move away from the T-shaped rod 24 and unfolding the sleeve rod 25. When the output rod of the electric push rod 22 retracts to its maximum distance, this process is repeated several times. The inclined inner wall of the hopper 4 near the discharge port is cleaned by a cleaning device 2. The output rod of the electric push rod 22 is extended or retracted to control the movement of each T-shaped rod 24 downward or upward inside the hopper 4. A spring 26 is installed inside the sleeve rod 25 so that the end of one T-shaped rod 24 away from the electric push rod 22 and the total length of the two sleeve rods 25 can be adapted to the width of the inclined inner wall of the hopper 4. The scraper 28 on the outer surface of the sleeve rod 25 is attached to the inner wall of the hopper 4 to scrape and clean the inclined inner wall of the hopper 4, so as to avoid material adhering to the inner wall of the hopper 4 near the discharge port and affecting the output rate of the material inside the hopper 4.

[0023] Reference Figure 2-5As shown in this embodiment: a round rod 29 is fixedly connected to one end of the inner wall of the sleeve rod 25. One end of the round rod 29 slides on the inner wall of the end of the T-shaped rod 24 away from the output rod of the electric push rod 22. When the sleeve rod 25 moves on the outer surface of the T-shaped rod 24, the round rod 29 will slide on the inner wall of the T-shaped rod 24. The round rod 29 can further limit the angle between the sleeve rod 25 and the T-shaped rod 24, increase the stability of the sleeve rod 25 when it moves, and prevent the angle of the sleeve rod 25 from deflecting. A reinforcing rod 210 is fixedly connected to the top of the T-shaped rod 24. The end of the reinforcing rod 210 away from the top of the T-shaped rod 24 is fixedly connected to one side of the output rod of the electric push rod 22. By setting the reinforcing rod 210, the connection between the T-shaped rod 24 and the output rod of the electric push rod 22 can be reinforced, and the connection between the T-shaped rod 24 and the output rod of the electric push rod 22 can be prevented from deforming or breaking under stress when the electric push rod 22 pushes the T-shaped rod 24 downward.

[0024] Reference Figure 2-5 As shown in this embodiment: a sealing ring 211 is fitted on the outer surface of the electric push rod 22. The sealing ring 211 is located outside the connection between the power rod and the output rod of the electric push rod 22. By setting the sealing ring 211, the connection between the power rod and the output rod of the electric push rod 22 can be further sealed, so as to avoid fine material powder inside the hopper 4 from entering the interior of the electric push rod 22 and affecting the normal use of the electric push rod 22.

[0025] Reference Figure 2-4As shown in this embodiment: the convenient component 23 includes two slotted plates 231, which are respectively fixed to both ends of the support rod 21. Several bolts 232 are inserted into the inner wall of the slotted plates 231. Several threaded holes 233 are respectively opened on both sides of the top of the hopper 4. The outer surface of the bolts 232 is threadedly connected to the inner wall of the threaded holes 233. When installing the cleaning device 2, the support rod 21 is hoisted to the bottom of the hopper 4 by a hoisting device, so that the bottom end of the support rod 21 is attached to the top of the hopper 4 and the slotted plates 231 are aligned with the threaded holes 233 on the outer surface of the hopper 4. Then, several bolts 232 are used to pass through the slotted plates 231 and insert into the threaded holes 233 on one side of the two slotted plates 231. The bolts 232 are rotated to make the bolts 232 threadedly connected to the inner wall of the threaded holes 233, thus fixing the slotted plates 231 and the support rod 21 to the top of the hopper 4. When the cleaning device 2 needs to be removed, the bolts are rotated on one side of the two slotted plates 231. 232 disengages each bolt 232 from the inside of the threaded hole 233, and then lifts the support rod 21 and cleaning device 2 as a whole using hoisting equipment. This allows users to choose whether to use the cleaning device 2 according to their needs. Several positioning blocks 234 are fixedly connected to the top of the hopper 4. Two positioning blocks 234 are fixed on the side of the top of the hopper 4 near the threaded hole 233. When installing the support rod 21, the two ends of the support rod 21 are respectively clamped between the two positioning blocks 234 on both sides of the top of the hopper 4. This allows for faster positioning of the support rod 21 and the groove plate 231 with the hopper 4, making it easier to use bolts 232 to pass through the groove plate 231 to connect the groove plate 231 to the hopper 4 and install the support rod 21. The edges of the outer surfaces of the two positioning blocks 234 that are close to each other are arc-shaped. By setting the edges of the outer surfaces of the two positioning blocks 234 that are close to each other to be arc-shaped, it is easier for the support rod 21 to enter between the two positioning blocks 234.

[0026] Working principle: When installing the cleaning device 2, the support rod 21 is hoisted to the bottom of the silo 4 using hoisting equipment, so that the bottom of the support rod 21 is attached to the top of the silo 4 and the slot plate 231 is aligned with the threaded hole 233 on the outer surface of the silo 4. Then, several bolts 232 are used on one side of the two slot plates 231, passing through the slot plates 231 and inserted into the threaded hole 233. The bolts 232 are rotated to make the bolts 232 threaded into the inner wall of the threaded hole 233, thus fixing the slot plate 231 and the support rod 21 to the top of the silo 4. When using the buffer silo, the material is added into the silo 4 through the feed inlet at the top of the silo 4. The hydraulic rod 5 is operated to retract, driving the valve plate 6. Moving the inner wall of frame rod 3 opens the discharge port at the bottom of hopper 4, allowing material inside hopper 4 to be discharged. When the feeding speed at the top of hopper 4 is greater than the discharge speed at the bottom, material accumulates inside hopper 4. When the discharge speed is greater than the feeding speed, material inside hopper 4 is discharged outwards. Extending hydraulic rod 5 moves valve plate 6 to one end, which then fits against the inner wall of frame rod 3, closing the discharge port at the bottom of hopper 4. When the material output speed inside hopper 4 decreases significantly without external influence, extending electric push rod 22 at the bottom of support rod 21 pushes each T-shaped rod through the output rod of electric push rod 22. As the T-shaped rod 24 moves downward inside the hopper 4, the rollers 27 on the outer surfaces of the two sleeve rods 25 located at one end of the T-shaped rod 24 roll on the inner wall of the hopper 4. The scraper 28 on one side of the two sleeve rods 25 can scrape off the material adhering to the inclined inner wall of the hopper 4. At the same time, as the T-shaped rod 24 descends, the two sleeve rods 25 on the outer surface are squeezed by the inner wall of the hopper 4 and slide in the same direction, compressing the internal spring 26. This makes the end of the T-shaped rod 24 away from the output rod of the electric push rod 22 and the total length of the two sleeve rods 25 match the width of the inclined inner wall of the hopper 4. After the output rod of the electric push rod 22 extends to its maximum distance, the electric push rod 22 is operated to control the movement. The output rod of the electric push rod 22 retracts, causing each T-shaped rod 24 to move upward. During the upward movement of the T-shaped rod 24, the compressed spring 26 inside the sleeve rod 25 returns to its original state, pushing the sleeve rod 25 to move away from the T-shaped rod 24 and unfolding the sleeve rod 25. After the output rod of the electric push rod 22 retracts to its maximum distance, this process is repeated several times to clean the inclined inner wall of the hopper 4 near the discharge port. When the cleaning device 2 needs to be removed, the bolts 232 are rotated on one side of the two slot plates 231 to disengage each bolt 232 from the inside of the threaded hole 233. Then, the support rod 21 and the cleaning device 2 can be lifted away as a whole by the hoisting equipment.
