Abstract
Description
Technical Field
[0001] This utility model relates to a rotary fabric feeding machine, and more particularly to a rotary fabric feeding machine in which the annular feed port of the fabric layer is sealed with an annular tape. Background Technology
[0002] With increasingly stringent environmental protection requirements, sealed rotary flatbed mixers are commonly used at the top of the coal tower in the production process of large top-charged coke ovens. The function of the sealed rotary flatbed mixer is to evenly distribute the blended and crushed qualified coal into the storage tank of the coal tower, improve the filling coefficient of the coal tower, ensure uniform distribution, reduce the segregation of coal in the coal tower, increase the coal tower storage capacity, and meet the production needs and environmental protection requirements of the coke oven.
[0003] The sealed rotary concrete placing boom mainly consists of a reversible rotating frame, a reversible belt conveyor, a power supply system, a circular track, and a sealing cover. The reversible belt conveyor is mounted on the reversible rotating frame and powered by the power supply system. Concrete placement is achieved through the forward and reverse rotation of the reversible belt conveyor and the reciprocating movement of the rotating frame along the circular track. The upper part of the belt surface of the reversible belt conveyor is equipped with a closed guide chute. The head and tail sections of the reversible belt conveyor are respectively equipped with head chutes and tail chutes. When the drive motor of the reversible belt conveyor rotates forward, the coal is placed through the head chutes; when the drive motor rotates backward, the coal is placed through the tail chutes. The coal is then evenly distributed into the storage tank of the coal tower directly through two annular discharge ports within the circular track.
[0004] The discharge port of a sealed rotary concrete placing boom has a sealing structure. The two main types of sealing are as follows:
[0005] 1) The fabric section adopts the method of installing an integral sealing cover on a reversible rotating frame to seal the area inside the circular track with the sealing cover, and the sealing cover and the circular track are sealed with a rubber sealing curtain.
[0006] 2) The fabric section adopts the method of installing two large and two small annular sealing covers on the reversible rotating frame. The inner areas of the two annular discharge ports are sealed with the corresponding annular sealing covers, and the corresponding annular sealing covers are sealed with rubber sealing curtains between them and the annular discharge ports.
[0007] The main problems with the above two sealing methods are:
[0008] 1) Both the integral sealing cover and the annular sealing cover need to be installed on the reversible rotating frame of the rotary placing boom. The sealing cover and its hanging parts greatly increase the equipment weight of the sealing rotary placing boom and also increase the driving load.
[0009] 2) Both the integral sealing cover and the annular sealing cover are installed on the reversible rotating frame. The sealing structure between them and the annular discharge port is relatively movable. The sealing effect of the relatively movable sealing structure is not ideal. The rubber sealing curtain is easily damaged due to friction during the movement, and there are also safety hazards. Summary of the Invention
[0010] This utility model provides a circular tape sealing rotary fabric feeder, which uses a flexible circular tape to seal the circular feed port. The circular tape is connected to a reversible belt conveyor through a tape reversing mechanism. When the reversible belt conveyor moves along the circular track with the rotary frame, it can reliably seal the circular feed port without increasing the travel drive load of the rotary frame.
[0011] To achieve the above objectives, the present invention adopts the following technical solution:
[0012] A rotary concrete spreading machine with annular tape sealing, located on top of a storage silo, includes a rotary spreading machine composed of a rotary frame and a reversible belt conveyor. The top of the storage silo has two annular discharge ports and an annular track. The rotary frame can rotate and move along the annular track around the axis of the storage silo. The reversible belt conveyor is mounted on the rotary frame, and its two discharge ends are respectively equipped with discharge chutes, each located directly above a corresponding annular discharge port. Annular tape is covered on each of the two annular discharge ports. The rotary spreading machine also has two... The reversible belt conveyor consists of a dust cover and two sets of belt redirection mechanisms. The dust cover is located at the bottom of the corresponding discharge chute, and a gap is left between the bottom edge of the dust cover and the top surface of the corresponding annular discharge port, which is sealed by a flexible dustproof strip. The belt redirection mechanism is located on the corresponding discharge chute and the dust cover. When the reversible belt conveyor moves with the rotating frame, the annular belt in front of the reversible belt conveyor is lifted upward under the guidance of the belt redirection mechanism along the direction of movement, passes around one side of the corresponding discharge chute, and then is laid flat again on the annular discharge port behind the reversible belt conveyor.
[0013] Furthermore, the storage bin is a coal tower of a coke oven, with a storage trough inside the coal tower, and two annular discharge ports located above the storage trough.
[0014] Furthermore, a circular tape-sealed rotary fabric laying machine also includes a control system; the drive end of the rotary frame and the drive end of the reversible belt conveyor are respectively connected to the control system.
[0015] Furthermore, the belt redirection mechanism consists of horizontal guide rollers, redirection rollers, vertical guide rollers, and idler rollers. Corresponding to the moving direction of the reversible belt conveyor, one set of horizontal guide rollers is provided on each side of the dust cover; one set of redirection rollers is provided on each side of the discharge chute; one set of vertical guide rollers and one set of idler rollers are provided at the outer end of the discharge chute between the two sets of redirection rollers; the annular belt is introduced from the horizontal guide roller on one side, changes from a horizontal state to a vertical state through the redirection roller on the corresponding side, then is guided by the vertical guide roller and idler roller to the other side, changes from a vertical state to a horizontal state through the redirection roller on the other side, and finally exits from the horizontal guide roller on the corresponding side.
[0016] 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 dust cover to the direction closer to the dust cover.
[0017] Furthermore, the modified guide roller is inclined.
[0018] Furthermore, the vertical guide roller is composed of multiple vertical inner guide rollers and vertical outer guide rollers spaced apart along the moving direction of the annular conveyor belt; multiple support rollers are provided between the vertical inner guide rollers and the vertical outer guide rollers to support the bottom of the vertical annular conveyor belt.
[0019] Furthermore, V-shaped belt cleaners are installed on the outer side of the dust cover at the corresponding horizontal guide rollers on both sides.
[0020] Furthermore, a feed inlet cleaner is installed on the inner wall of the bottom of the dust cover near the horizontal guide rollers on both sides, and a cleaning alarm is installed on the upper part of the outer side of the dust cover on the corresponding side; the feed inlet cleaner 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.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1) A flexible ring-shaped tape is used to seal the ring-shaped discharge port. Except for the area in the dust cover area where the dust cover partially covers the ring-shaped discharge port, the rest of the area is covered by the ring-shaped tape, thereby achieving effective sealing when moving the material.
[0023] 2) The annular belt is connected to the reversible belt conveyor through the belt redirection mechanism. Only part of the weight of the annular belt (dust cover area) is borne by the rotary frame, while the weight of the rest of the annular belt is borne by the top structure of the coal tower around the annular discharge port. Compared with the sealing structure of conventional sealed rotary concrete placing machines, this greatly reduces the overall weight of the rotary concrete placing machine and also reduces the driving load of the rotary frame.
[0024] 3) Compared with the method of installing a rigid sealing cover on a reversible rotary frame, the present invention uses a flexible annular tape to achieve sealing, which avoids the hard interference that may occur between two relatively moving devices and ensures the safe and reliable operation of the sealed rotary fabric placing machine.
[0025] 4) The annular discharge port is sealed with a ring-shaped tape. The structure is simple, the sealing effect is good, and it can effectively prevent dust and particulate matter from overflowing, which is beneficial to environmental protection. Attached Figure Description

[0034] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:
[0035] like Figures 1-3As shown, the circular tape sealing rotary material distribution machine of this utility model is located on the top of a storage silo and includes a rotary material distribution machine composed of a rotary frame 2 and a reversible belt conveyor 3. The top of the storage silo is provided with two circular discharge ports and a circular track 1. The rotary frame 2 can rotate and move along the circular track 1 with the storage silo axis as the center. The reversible belt conveyor 3 is located on the rotary frame 2, and two discharge chutes 4 are respectively provided at the two discharge ends of the reversible belt conveyor 3.

Figure 4 As shown), the rotary fabric feeder is also equipped with two dust covers 9 and two sets of belt redirection mechanisms 5; the dust covers 9 are located at the bottom of the corresponding discharge chute 4, and a gap is left between the bottom edge of the dust cover 9 and the top surface of the corresponding annular discharge port and sealed by a flexible dustproof strip; the belt redirection mechanisms 5 are located on the corresponding discharge chute 4 and the dust covers 9; when the reversible belt conveyor 3 rotates and moves with the rotary frame 2, along the direction of movement, the annular belt 7 in front of the reversible belt conveyor 3 is lifted up under the guidance of the belt redirection mechanism 5, passes around from one side of the corresponding discharge chute 4, and then is laid flat again on the annular discharge port behind the reversible belt conveyor 3.
[0036] Furthermore, the storage bin is a coal tower of a coke oven, with a storage trough inside the coal tower, and two annular discharge ports located above the storage trough.
[0037] Furthermore, a circular tape-sealed rotary fabric laying machine also includes a control system; the drive end of the rotary frame 2 and the drive end of the reversible belt conveyor 3 are respectively connected to the control system.
[0038] Furthermore, such as Figures 5-7 As shown, the belt redirection mechanism 5 consists of a horizontal guide roller 51, a redirection guide roller 52, a vertical guide roller 53, and an idler roller 54. Corresponding to the moving direction of the reversible belt conveyor 3, a set of horizontal guide rollers 51 are respectively provided on both sides of the dust cover 9; a set of redirection guide rollers 52 are respectively provided on both sides of the discharge chute 4; a set of vertical guide rollers 53 and a set of idler rollers 54 are respectively provided at the outer end of the discharge chute 4 between the two sets of redirection guide rollers 52; the annular belt 7 is introduced from the horizontal guide roller 51 on one side, changes from a horizontal state to a vertical state through the redirection guide roller 52 on the corresponding side, and then is guided to the other side by the vertical guide roller 53 and the idler roller 54. It changes from a vertical state to a horizontal state through the redirection guide roller 52 on the other side, and finally exits from the horizontal guide roller 51 on the corresponding side.
[0039] Furthermore, the horizontal guide roller 51 consists of at least three horizontal guide rollers, and the height of each horizontal guide roller increases sequentially from the direction away from the dust cover 9 to the direction closer to the dust cover 9.
[0040] Furthermore, the guide roller 52 is inclined.

[0043] Further, blanking port cleaners 11 are respectively installed on the inner walls of the bottoms of the dust covers 9 near the two horizontal guide rollers 51 on both sides, and cleaning alarm devices 8 are respectively installed on the upper parts of the outer sides of the corresponding dust covers 9; the blanking port cleaners 11 are provided with strain gauge pressure sensors, and the signal output ends of the strain gauge pressure sensors are connected to the triggering ends of the cleaning alarm devices 8.
[0044] The annular belt sealed rotary batching machine of the present utility model includes a reversibly traveling rotary frame 2 conventionally provided in a rotary batching machine, a reversible belt conveyor 3 (blanking chutes 4 are respectively arranged at both ends of the reversible belt conveyor 3) arranged on the rotary frame 2, and an annular track 1 arranged on the top of the storage bin, a power supply system 6 for supplying power to all electrical devices, etc. The difference from a conventional sealed rotary batching machine lies in that the present utility model uses an annular belt 7 to seal the two annular blanking ports at the top of the storage bin.
[0045] The storage bin of the present utility model mainly refers to a coal tower配套 with a coke oven. The annular track 1 is laid on the floor slab at the top of the coal tower with the axis of the coal tower as the center, and the rotary frame 2 rotates and travels along the annular track 1. The reversible belt conveyor 3 is installed on the rotary frame 并随之移动。
[0046] For the annular belt sealed rotary batching machine of the present utility model, in order to achieve the seal in the form of an annular belt, a belt redirecting mechanism 5 is provided, a dust cover 9 is arranged on the blanking chute 4 of the reversible belt conveyor 3, and optionally, a V-shaped belt cleaner 10, a blanking port cleaner 11 and a cleaning alarm device 8 are configured.
[0047] The dust cover 9 is installed at the bottom of the blanking chutes 4 at both ends of the reversible belt conveyor 3, and a flexible dust-proof strip is provided at the bottom edge thereof to achieve the seal with the annular blanking port during the moving process.
[0048] The belt redirecting mechanism 5 is composed of horizontal guide rollers 51, redirecting guide rollers 52, vertical guide rollers 53 and supporting rollers 54; when the reversible belt conveyor 3 rotates and moves along with the rotary frame 2, along the moving direction, the annular belt 7 in front of the reversible belt conveyor 3 is lifted upward under the guidance of the belt redirecting mechanism 5, bypasses from one side of the corresponding blanking chute 4, and then is re-laid on the annular blanking port behind the reversible belt conveyor 3.
[0049] 注:原文中“可逆带式输送机3安装在回转架2上并随之移动。”一句翻译中最后“并随之移动”的翻译“and随之移动”有误,已修正为“and moves along with it” ,但按照任务要求,仅返回符合格式的翻译内容,不做额外说明。The V-shaped tape cleaner 10 is installed on the lower outer side of the dust cover 9; the discharge port type cleaner 11 is installed on the inner bottom of the dust cover 9; the cleaning alarm 8 is installed on the upper outer side of the dust cover 9. The cleaning alarm 8 is powered by the power supply system 6 of the rotary fabric laying machine, and its trigger end is electrically connected to the signal output end of the strain gauge pressure sensor installed on the discharge port cleaner 11.
[0050] The working process of the annular belt-sealed rotary concrete placing machine described in this utility model is as follows: When the material level in the storage bin is lower than the set lower limit, the level gauge sends a loading signal to the control system. The control system sends an interlock start signal to the annular belt-sealed rotary concrete placing machine. First, it sends a forward or reverse rotation command to the drive motor of the reversible belt conveyor 3 and supplies power to start it. Then, it sends a forward or reverse rotation command to the traveling motor of the rotary frame 2 and supplies power to start it. The rotary frame 3 rotates and moves along the annular track 1 with the storage bin axis as the center. The material transported by the belt conveyor above the rotary concrete placing machine falls onto the belt surface of the reversible belt conveyor 3 below through the belt conveyor head chute, and then falls into the storage bin below the corresponding annular discharge port through the discharge chute 4 at one end of the reversible belt conveyor 3. During the process of the rotary fabric feeder uniformly feeding material while rotating along the annular track 1, the material discharge point is covered and sealed by a dust cover 9. In other areas, the remaining area of the annular discharge port is covered and sealed by an annular conveyor belt 7. Where the dust cover 9 passes, the annular conveyor belt 7 is rolled up by the conveyor belt redirection mechanism 5 and loops around one side of the discharge chute 4 before falling back to its original position.
[0051] Before the annular tape 7 enters the tape redirection mechanism 5, the V-shaped tape cleaner 10 removes any material adhering to the annular tape 7 to prevent it from being carried into the tape redirection mechanism 5. Material scattered on the edge of the annular discharge port during discharge through the discharge chute 4 is swept into the annular discharge port by the discharge port cleaner 11 to prevent it from sticking to the annular tape 7 and affecting the sealing effect. When the discharge port cleaner 11 encounters material that is difficult to remove, the strain gauge pressure sensor sends a signal, triggering an alarm through the cleaning alarm 8 to remind on-site personnel to clean the area promptly.
[0052] 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 concept of the present utility model, should be included within the protection scope of the present utility model.
