Description

Technical Field

[0001] This application relates to the technical field of coal transportation. Specifically, it relates to a viscous material conveying device. Background Art

[0002] As the core supporting system of the gasification device and the power plant, the raw coal storage and transportation device is equipped with 22 coal conveying belts and 12 slag conveying belts, building a full-process operation system covering raw coal transportation, fuel coal blending, and solid waste outward transportation. The system adopts a hierarchical conveying design. Among them, the coal conveying belts are divided into a raw coal conveying special line (belt width 1400 - 2200 mm) and a fuel coal transfer branch line (belt width 1200 - 1600 mm) according to their functions. The longest single conveying distance reaches 1050 meters, and the maximum inclination angle is 17 degrees. The total length of the overall belt network exceeds 19,000 meters. At the same time, it undertakes the outward transportation of solid waste generated from the production of raw materials and fuel coal. The power and gasification boilers generate approximately 10,000 tons of solid waste per day. The filter residue with a moisture content of 10% - 15% generated by the gasification device is transported to the transfer station through a flame-retardant belt (belt width 1600 mm, belt speed 1.6 m / s) with temperature monitoring and anti-deviation devices after being pressure-filtered, and is accurately discharged and loaded through a multi-channel distributor, and then transported to the slag yard by an outward transportation vehicle. The slag conveying belt adopts a double-drum triple-drive mode, equipped with a 630 kW explosion-proof motor and a Φ159 mm wear-resistant idler group, which can adapt to the transportation of complex terrains from -6° to 17°.

[0003] In the existing gasification slag transfer system, the material transfer between the upstream and downstream belt conveyors adopts a gravity self-flowing slag dropping pipe design, and the inclination angle is designed to be 55 - 60° to balance the material flow rate and anti-blocking requirements. The upstream belt conveyor usually transports the gasification slag to the downstream belt conveyor through a slag dropping pipe with a certain inclination, and a bar gate is set on the slag dropping pipe to control the opening and closing of the channel.

[0004] However, in the transportation process of the existing technology, due to the physical properties of gasification slag such as high viscosity, high moisture content, and fine particles, although the existing slag dropping pipe adopts an inclined structure and a bar gate is set for flow regulation, during continuous operation, the gasification slag is easily adhered to the surface of the slag dropping pipe, resulting in frequent blockage of the slag dropping pipe. It can only rely on manual cleaning at regular intervals, which takes a long time for a single operation, reduces the transportation efficiency, and the frequent manual cleaning has a high risk, seriously affecting the safe and stable operation of the equipment. Therefore, there are deficiencies. Summary of the Invention

[0005] To make up for the above deficiencies, the present invention provides a viscous material conveying device, which uses a slag bin and a scraper conveyor to connect the belt conveyors between the upstream and downstream to transport the work, can effectively transport the gasification slag, reduce the problem of frequent blockage, and will not cause slag scattering during the transportation process, reducing manual cleaning and improving the transportation efficiency and safe production.

[0006] This application is implemented as follows:

[0007] An upstream belt conveyor, with a blanking cylinder provided at the lower port of the upstream belt conveyor;

[0008] A slag bin, which is fixedly communicated with the bottom end of the blanking cylinder;

[0012] In an embodiment of this application, a feed inlet is opened on one side of the blanking cylinder, and the blanking end of the upstream belt conveyor is inserted into the feed inlet.

[0013] In an embodiment of this application, the slag bin is of a cylindrical structure, and a polytetrafluoroethylene coating is applied inside the slag bin.

[0014] In an embodiment of this application, the buffer cone barrel includes a cone barrel body and a diversion baffle. The cone barrel body is fixedly connected to the bottom end of the connecting cylinder, and the diversion baffle is fixedly connected to the bottom end of the cone barrel body.

[0015] In an embodiment of this application, an emergency plug valve is arranged between the cone barrel body and the diversion baffle.

[0016] In an embodiment of this application, the transport scraper conveyor includes a transport housing and a double-chain scraper member. A feed inlet is opened at the upper end of the transport housing, and a discharge outlet is opened at the lower end of the transport housing. The bottom of the buffer cone barrel is inserted into the feed inlet, the discharge outlet is fixedly communicated with the guiding member, and the double-chain scraper member is arranged inside the transport housing.

[0017] In an embodiment of this application, a transport plate is fixedly connected inside the transport scraper conveyor. One end of the transport plate is located on one side of the feed inlet, and the other end of the transport plate is located on one side of the discharge outlet.

[0018] In an embodiment of the present application, the double-chain scraper member includes a driving shaft, a driving wheel, a rotating motor, a driven shaft, a driven wheel, a chain, and a scraper. The driving shaft is rotatably connected to the upper end of the transport housing. The driving wheels are symmetrically connected to the driving shaft. The output end of the rotating motor is fixedly connected to the driving shaft. One end of the chain is engaged with the driving wheel. The driven shaft is rotatably connected to the lower end of the transport housing. The driven wheels are symmetrically connected to the driven shaft.

[0020] In an embodiment of the present application, a sealing rubber strip is fixedly connected to the bottom of the material guiding groove, and the sealing rubber strip is attached to the surface of the downstream belt conveyor.

[0021] The beneficial effects of the present application are as follows: During use, the gasified slag falls into the slag bin through the upstream belt conveyor. In the slag bin, there is no dead angle for the accumulation of gasified slag, and it is difficult to become blocked. Through the double-cone angle design formed by the buffer cone barrel, the gasified slag slowly falls onto the transport scraper, and the vibrator further vibrates the connecting cylinder and the buffer cone barrel to reduce the thickness of the gasified slag adhering to the inner wall of the buffer cone barrel. By starting the transport scraper, the gasified slag is evenly transported onto the downstream belt conveyor. And by providing the material guiding member, when the gasified slag falls from the transport scraper onto the downstream belt conveyor, there is no falling gap between the transport scraper and the downstream belt conveyor, so that the situation of material scattering will not occur, avoiding manual cleaning of scattered materials and the risk of being involved in the belt due to the working equipment, thus solving the problems in the prior art that the inclined slag dropping cylinder is prone to blockage, only relying on manual cleaning at regular intervals, with low transport efficiency, and the risk is relatively high during frequent manual cleaning, seriously affecting the safe and stable operation of the equipment.

[0029] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] As Figures 1 - 5 shown, a viscous material conveying device according to an embodiment of the present application includes:

[0031] An upstream belt conveyor 100, and a blanking cylinder 200 is provided at the lower port of the upstream belt conveyor 100;

[0032] A slag bin 300, and the slag bin 300 is fixedly communicated with the bottom end of the blanking cylinder 200;

[0033] A buffer cone 500, the buffer cone 500 is fixedly communicated with the bottom end of the slag bin 300 through a connecting cylinder 400, a vibrator 600 is installed on the outer side surface of the buffer cone 500, and the buffer cone 500 and the slag bin 300 are flexibly connected through the connecting cylinder 400. When the vibrator 600 vibrates, the vibration amplitude of the buffer cone 500 is relatively large, and the slag bin 300 is less affected by the vibration. The vibrator 600 adopts an eccentric block double-shaft structure;

[0034] A transportation scraper 700, and the transportation scraper 700 is arranged at the bottom end of the buffer cone 500;

[0035] The material guide member 800 is fixedly connected to the bottom of the transport scraper 700. A downstream belt conveyor 900 is arranged below the material guide member 800. It should be noted that a plurality of upstream belt conveyors 100 are arranged according to actual needs. The upstream belt conveyor 100 simultaneously transports the gasified slag to the downstream belt conveyor 900, thereby improving the overall transportation speed. When in use, the gasified slag falls into the slag bin 300 through the upstream belt conveyor 100. There is no dead corner for the gasified slag to accumulate in the slag bin 300, and it is difficult to get blocked. Then, a double cone angle design is formed by the buffer cone barrel 500, so that the gasified slag slowly falls onto the transport scraper 700, and the connecting tube 400 and the buffer cone barrel 500 are further vibrated by the vibrator 600 to reduce the thickness of the gasified slag attached to the inner wall of the buffer cone barrel 500. The transport scraper 700 is started to evenly transport the gasified slag to the downstream belt conveyor 900, and the gasified slag is evenly transported to the downstream belt conveyor 900. By setting the material guide piece 800, when the gasified slag falls from the transport scraper 700 to the downstream belt conveyor 900, there is no falling gap between the transport scraper 700 and the downstream belt conveyor 900, so that material spillage will not occur, avoiding the risk of manual cleaning of scattered material and the risk of the working equipment being drawn into the belt, thereby solving the problem in the prior art that the inclined slag dropping barrel is prone to blockage and can only be cleaned manually regularly and uninterruptedly, with low transportation efficiency, and frequent manual cleaning, which is risky and seriously affects the safe and stable operation of the equipment.

[0036] like Figure 2 As shown, a feeding port 210 is provided on one side of the blanking barrel 200, and the blanking end of the upstream belt conveyor 100 is inserted into the feeding port 210. The blanking end of the upstream belt conveyor 100 is inserted into the feeding port 210, so that the gasified slag will not be scattered outward when it falls into the blanking barrel 200.

[0037] Furthermore, the slag bin 300 is a cylindrical structure, and a polytetrafluoroethylene coating is applied inside the slag bin 300. By setting the slag bin 300 as a cylindrical structure, and the upper and lower surface areas of the slag bin 300 are much larger than the lower surface area of ​​the blanking barrel 200, the gasified slag is not easily attached to the inner side of the slag bin 300 by applying a polytetrafluoroethylene coating on the inner side of the slag bin 300, so that the gasified slag is not easily affected by the use area of ​​the slag bin 300.

[0038] Further, the buffer cone 500 includes a cone body 510 and a diversion baffle 520. The cone body 510 is fixedly connected to the bottom end of the connecting cylinder 400, and the diversion baffle 520 is fixedly connected to the bottom end of the cone body 510. It should be noted that the inner side of the buffer cone 500 is also coated with a polytetrafluoroethylene coating so that the gasified slag is not easily attached to the inner side of the buffer cone 500. The falling port areas of the cone body 510 and the diversion baffle 520 are the same, but the surface inclination degrees are different, thus forming a double-cone angle design, which slows down the falling speed of the gasified slag multiple times, thereby reducing the falling impact force of the gasified slag and preventing excessive impact force from damaging the transport scraper 700.

[0039] Further, an emergency plug valve 530 is provided between the cone body 510 and the diversion baffle 520. The emergency plug valve 530 is used to prevent the gasified slag from falling during maintenance or in an emergency.

[0040] As Figure 3 shown, the transport scraper 700 includes a transport housing 710 and a double-chain scraper member 720. An inlet 730 is opened at the upper end of the transport housing 710, and an outlet 740 is opened at the lower end of the transport housing 710. The bottom of the buffer cone 500 is inserted into the inlet 730, and the outlet 740 is fixedly communicated with the guiding member 800. The double-chain scraper member 720 is arranged inside the transport housing 710. The gasified slag enters through the inlet 730 and exits through the outlet 740. The double-chain scraper member 720 can make the gasified slag discharge dynamically and evenly. A transport plate 750 is fixedly connected inside the transport scraper 700. One end of the transport plate 750 is located on one side of the inlet 730, and the other end of the transport plate 750 is located on one side of the outlet 740. By starting the double-chain scraper member 720, the gasified slag entering through the inlet 730 moves evenly on the transport plate 750, and thus falls evenly from the outlet 740.

[0041] As Figure 4As shown in the figure, the double-chain scraper part 720 includes a driving shaft 721, a driving wheel 722, a rotating motor 723, a driven shaft 724, a driven wheel 725, a chain 726 and a scraper 727. The driving shaft 721 is rotatably connected to the upper end of the transportation housing 710. The driving wheels 722 are symmetrically connected to the driving shaft 721. The output end of the rotating motor 723 is fixedly connected to the driving shaft 721. One end of the chain 726 is engaged with the driving wheel 722. The driven shaft 724 is rotatably connected to the lower end of the transportation housing 710. The driven wheels 725 are symmetrically connected to the driven shaft 724. The other end of the chain 726 is engaged with the driven wheel 725. A plurality of scrapers 727 are provided and are evenly fixed between the chains 726. By starting the rotating motor 723, the driving shaft 721 rotates, driving the driving wheel 722 to rotate, driving the engaged chain 726 to rotate, so that the driven wheel 725 rotates, thereby driving the driven shaft 724 to rotate, so that the scrapers 727 on the chain 726 rotate cyclically, so that the gasified slag entering from the feed port 730 uniformly falls from the discharge port 740.

[0042] As Figure 5 shown in the figure, the material guiding part 800 includes a material guiding groove 810 and a guiding port 820. The material guiding groove 810 is fixedly connected below the transportation scraper 700. The guiding port 820 is fixedly connected to the side of the material guiding groove 810. By providing the material guiding groove 810 and the guiding port 820, the gap between the discharge port 740 and the downstream belt conveyor 900 is shortened. The gasified slag is guided through the guiding port 820 to the transportation position of the downstream belt conveyor 900, preventing the downstream belt conveyor 900 from frequently adjusting.

[0043] Furthermore, a sealing rubber strip 830 is fixedly connected to the bottom of the material guiding groove 810, and the sealing rubber strip 830 is attached to the surface of the downstream belt conveyor 900. The sealing rubber strip 830 makes there be no obvious gap between the material guiding groove 810 and the downstream belt conveyor 900, thereby avoiding the risk of gasified slag spilling.

[0044] In summary, the working principle of a viscous material conveying device according to an embodiment of the present invention is as follows: During use, the gasified slag is transported by the upstream belt conveyor 100 and falls from the feeding cylinder 200 into the slag bin 300. The slag bin 300 is set as a cylindrical structure, and the upper and lower surface areas of the slag bin 300 are much larger than the lower surface area of the feeding cylinder 200, so that there are no accumulation dead corners of the gasified slag in the slag bin 300. By applying a polytetrafluoroethylene coating on the inner side of the slag bin 300, the gasified slag is not easily attached to the inner side of the slag bin 300, making it difficult for the gasified slag to be blocked in the slag bin 300. Then, a double-cone angle design is formed by the cone barrel body 510 and the guide baffle 520 to buffer multiple times and reduce the falling impact force of the gasified slag. Then, it falls onto the conveying plate 750 through the feeding port 730, and the vibrator 600 is always started during the falling process to further vibrate the vibration connection cylinder 400 and the buffer cone barrel 500, thereby reducing the thickness of the gasified slag attached to the inner wall of the buffer cone barrel 500. By starting the rotating motor 723, the driving shaft 721 rotates, driving the driving wheel 722 to rotate, driving the meshing chain 726 to rotate, so that the driven wheel 725 rotates, driving the driven shaft 724 to rotate, and the scraper 727 on the chain 726 rotates in a cycle, so that the gasified slag entering from the feeding port 730 uniformly falls from the discharging port 740, and the gasified slag is uniformly transported onto the downstream belt conveyor 900. By setting the guiding groove 810 and the sealing rubber strip 830, when the gasified slag falls from the conveying scraper 700 onto the downstream belt conveyor 900, there is no falling gap between the conveying scraper 700 and the downstream belt conveyor 900, so that the situation of material scattering will not occur, avoiding manual cleaning of scattered materials and the risk of being involved in the belt due to the working equipment, thus solving the problems in the prior art that the inclined slag dropping cylinder is prone to blockage, can only rely on manual regular and continuous cleaning, has low transportation efficiency, and the manual frequent cleaning has a large risk, seriously affecting the safe and stable operation of the equipment.
