Description

Technical Field

[0001] This utility model relates to the field of mobile sealing technology, and in particular to an annular tape sealing structure for rotating fabric distribution when an annular feed port is used. Background Technology

[0002] The rotary feeding machine in the coal preparation workshop is used to deliver the prepared, qualified coal to the coal tower for storage to meet the production needs of the coke oven. The coal is transported by a belt conveyor and then evenly distributed into the coal tower from the annular discharge port at the top of the coal tower by the rotary feeding machine. In the rotary feeding machine, the rotary trolley, controlled by the control system, travels reversibly on the annular track with a rotation angle of ±360°. The rotary trolley is equipped with a reversible belt conveyor, and the feeding position is controlled by the control system, selecting the lowest point of the material within a 360° range according to the production process requirements.

[0003] A conventional fully sealed reversible rotary concrete placing machine (referred to as a sealed rotary concrete placing machine) consists of a placing machine body, a drive unit and base, a traveling device, a central rotary support (including a current collector), an integrally sealed frame, a guide chute, and a traveling track, etc., and has the functions of bidirectional placing, bidirectional rotation, and full sealing. For example, the "Fully Sealed Rotary Concrete Placing Machine" disclosed in Chinese Utility Model Patent No. CN 203699418 U includes a current collector, a ring track, a sealing cover, a reversible rotary frame, a belt conveyor, a head chute, a sealed guide chute, and a sealed rotary receiving hopper. The ring track is set on the floor slab of the material placing layer of the storage tank with the current collector as the center. The sealing cover is connected to the reversible rotary frame and fixed together on the ring track. The sealed guide chute is fixed on the belt conveyor and connected to the head chute. The lower center of the sealed rotary receiving hopper is aligned with the center of the current collector and fixedly connected to the top of the sealed guide chute, and its upper part is fixed to the outlet of the head chute. Its advantages are: it achieves a fully sealed process from receiving and conveying materials to distributing them, preventing material dust from spilling out. It also ensures that the material always flows in the same direction as the reversible belt conveyor during rotation. However, due to the use of an integrated sealed cover, the equipment is bulky, structurally complex, heavy, and consumes a lot of energy. Summary of the Invention

[0008] Furthermore, the horizontal guide roller section consists of at least three horizontal guide rollers, and the height of each horizontal guide roller increases sequentially from the direction away from the rotary fabric device to the direction closer to the rotary fabric device.

[0009] Furthermore, the redirecting guide roller is inclined, and the axial direction of the redirecting guide roller is arranged radially along the annular feed opening.

[0035] The following embodiments are implemented based on the technical solution of this utility model, providing detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments. Unless otherwise specified, the methods used in the following embodiments are conventional methods.

Example

[0037] like Figure 5 As shown, in this embodiment, the storage silo is a coal tower, and the top of the coal tower is provided with two annular discharge ports 4. The rotary material distribution device 2 is a sealed rotary material distribution machine, which adopts an annular tape sealing method.

[0038] The sealed rotary concrete placing boom includes a rotary trolley 10 and a reversible belt conveyor 11. The top of the coal tower is equipped with two annular discharge ports 4 and an annular track 12. The rotary trolley 10 rotates along the annular track 12 with the coal tower axis as the center. The reversible belt conveyor 11 is mounted on the rotary trolley 10. The two discharge ends of the reversible belt conveyor 11 are respectively equipped with discharge chutes 5, which are located directly above the corresponding annular discharge ports 4. The two annular discharge ports 4 are each covered with annular conveyor belts 1. The sealed rotary concrete placing boom also has two sealing... The reversible belt conveyor 11 is equipped with a cover 6 and two sets of belt redirection mechanisms 3. The sealing cover 6 is located at the bottom of the corresponding discharge chute 5. A gap is left between the bottom edge of the sealing cover 6 and the top surface of the corresponding annular discharge port 4 and sealed by a flexible dustproof strip. The belt redirection mechanism 3 is located on the corresponding discharge chute 5 and the sealing cover 6. When the reversible belt conveyor 11 rotates with the trolley 10, the annular belt 1 in front of it is lifted up under the guidance of the belt redirection mechanism 3 along the direction of movement, passes around the side of the corresponding discharge chute 5, and then is laid flat again on the annular discharge port 4 behind it.

[0039] like Figures 2-4 As shown, in this embodiment, the belt redirection mechanism 3 consists of a horizontal guide roller 31, a redirection guide roller 32, a vertical guide roller 33, and an idler roller 34. Corresponding to the moving direction of the reversible belt conveyor 11, a set of horizontal guide rollers 31 are respectively provided on both sides of the sealing cover 6; a set of redirection guide rollers 32 are respectively provided on both sides of the discharge chute 5; a set of vertical guide rollers 33 and a set of idler rollers 34 are respectively provided at the outer end of the discharge chute 5 between the two sets of redirection guide rollers 32.

[0040] In this embodiment, the horizontal guide roller 31 consists of three horizontal guide rollers, and the height of each horizontal guide roller increases sequentially from the direction away from the sealing cover 6 to the direction closer to the sealing cover 6. The deflection guide roller 32 is inclined, and the axial direction of the two sets of deflection guide rollers 32 is consistent with the radial direction of the corresponding annular discharge port 4.

[0041] In this embodiment, the vertical guide roller 33 is composed of multiple vertical inner guide rollers and vertical outer guide rollers spaced apart along the moving direction of the annular belt 1; the support roller 34 is multiple and is disposed between the vertical inner guide rollers and the vertical outer guide rollers, and is used to support the bottom of the vertical annular belt 1.

[0042] In this embodiment, V-shaped tape cleaners are installed on the outer side of the sealing cover 6 at the corresponding horizontal guide rollers 31 on both sides. At the bottom of the sealing cover 6, discharge port cleaners 9 are installed on the inner wall near the horizontal guide rollers 31 on both sides. Cleaning alarms 7 are installed on the upper outer side of the sealing cover 6 on the corresponding sides. The discharge port cleaner 9 is equipped with a strain gauge pressure sensor, and the signal output terminal of the strain gauge pressure sensor is connected to the trigger terminal of the cleaning alarm 9.

[0043] When the material level in the coal tower is lower than the set lower limit, the level gauge sends a loading signal to the control system. The control system then sends an interlock start signal to the sealed rotary concrete distributor. First, it sends a forward or reverse rotation command to the drive motor of the reversible belt conveyor 11 and powers it to start the machine. Then, it sends a forward or reverse rotation command to the traveling motor of the rotary trolley 10 and powers it to start the machine. The rotary trolley 10 rotates and moves along the circular track 12 with the coal tower axis as the center. The material transported by the belt conveyor above the sealed rotary concrete distributor falls onto the belt surface of the reversible belt conveyor 11 below through the chute at the head of the belt conveyor, and then falls into the storage tank of the coal tower below the corresponding circular discharge port 4 through the discharge chute 5 at one end of the reversible belt conveyor 11. During the process of the sealed rotary concrete distributor rotating and moving along the circular track 12 to distribute the material evenly, the discharge point is sealed by the sealing cover 6. The area above the material inlet 4 is covered and sealed, while the remaining area is covered and sealed by the annular tape 1. Where the sealing cover 6 passes, the annular tape 1 is rolled up by the tape redirection mechanism 3 and goes around the side of the discharge chute 5 before falling back to its original position. Before the annular tape 1 enters the tape redirection mechanism 3, the V-shaped tape cleaner removes the material adhering to the annular tape 1 to prevent it from being carried into the tape redirection mechanism 3. The material scattered on the edge of the annular discharge inlet 4 when the material is discharged through the discharge chute 5 is swept into the annular discharge inlet 4 by the discharge inlet cleaner 9 to prevent the material from sticking to the annular tape 1 and affecting the sealing effect. When the discharge inlet cleaner 9 encounters material that is difficult to remove, the strain gauge pressure sensor sends a signal, which triggers an alarm through the cleaning alarm 7 to remind the on-site personnel to clean it in time.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
