Description

Technical Field

[0001] This utility model relates to the field of buried scraper conveyors, and in particular to a buried scraper conveyor for conveying high-temperature materials. Background Technology

[0002] A scraper conveyor is a transport device that continuously conveys bulk materials within a closed rectangular cross-section casing using a moving scraper chain. During material transport, the material passes through the upper scraper chain and falls onto the lower scraper chain, which then carries the material further. The scraper chain transports material within the enclosed trough, buried within the conveyed material. If the material temperature is very high, such as exceeding 200°C, it can have several negative impacts on the chain. Firstly, there's the issue of material strength. The strength of metallic materials decreases at high temperatures, especially above 300°C, where the strength of ordinary carbon steel decreases significantly. This makes the chain more prone to deformation and even breakage under tension and impact. Secondly, there's the issue of thermal expansion. Different materials have different coefficients of thermal expansion; for example, chain rods and pins may experience changes in their fit clearance after temperature increases. What was originally a suitable clearance may become tighter due to expansion, causing jamming or additional stress. High temperatures also affect the chain's wear resistance. While chains are usually heat-treated to increase surface hardness, prolonged exposure to high temperatures will reduce surface hardness, making the chain more susceptible to wear. Increased wear not only shortens the lifespan of the chain, but may also lengthen the chain and affect transmission accuracy. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a buried scraper conveyor for conveying high-temperature materials, which isolates the chain rods in the scraper chain from the conveyed materials, thereby reducing the impact of high-temperature materials on the scraper chain.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A submerged scraper conveyor for conveying high-temperature materials includes a housing, a scraper chain, a drive unit, a head wheel assembly, and a tail wheel assembly. The housing includes a cover plate, which is connected to a bottom plate via irregularly shaped side plates. Side liners are vertically fixed on the left and right irregularly shaped side plates, and the side liners, the lower part of the irregularly shaped side plates, and the bottom plate constitute the chain movement area of ​​the scraper chain. The scraper chain includes scrapers, which are connected to a conveyor chain via connecting plates. The connecting plates and the side liners constitute a separation zone between the scrapers and the conveyor chain.

[0005] The lower end of the connecting plate is flush with the scraper, and the upper end is higher than the scraper.

[0006] The irregular side plate includes a first L-shaped part, the horizontal section of the first L-shaped part is arranged upward and outward, the vertical part of the first L-shaped part is connected to the inclined side, the inclined side is arranged inward and downward, the lower end of the inclined side is connected to the vertical part of the second L-shaped part, the horizontal part of the second L-shaped part is outward and connected to the vertical part of the third L-shaped part, and the horizontal section of the third L-shaped part is arranged downward and outward.

[0007] Side heat dissipation plates are arranged at intervals along the length direction within the trapezoidal interval formed by the hypotenuse and the second L-shaped section, and the side heat dissipation plates are perpendicular to the irregular side plates.

[0008] An upper guide rail support plate is welded to the upper end of the inclined side, an upper guide rail is installed on the upper guide rail support plate, and a heat-insulated lower guide rail is installed on the bottom plate.

[0009] The heat-insulated lower guide rail includes a lower guide rail, which is mounted on an inverted U-shaped support plate, and a heat-insulating gasket is installed inside the inverted U-shaped support plate.

[0010] The inverted U-shaped support plate has slits spaced along its length at its lower part.

[0011] The heat insulation pad is a ceramic fiber heat insulation pad.

[0012] This utility model provides a buried scraper conveyor for conveying high-temperature materials, which has the following technical advantages: 1) By setting irregular side plates, the lower part of the irregular side plates forms the chain movement area. The irregular side plates are vertically provided with side lining plates. The side lining plates and the connecting plate of the scraper chain form an isolation zone, which can separate the material from the scraper chain, thus avoiding the chain from being affected by the high temperature of the material.

[0013] 2) By welding heat dissipation plates to the irregular side plates, the heat dissipation plates can dissipate the heat of the material as heat dissipation fins; at the same time, heat insulation pads are arranged at the lower guide rail to prevent the heat of the material from being transferred to the chain, thereby reducing the impact of high temperature on the chain.

Detailed Implementation

[0023] like Figure 1 As shown, a submerged scraper conveyor for conveying high-temperature materials includes a housing, which is sequentially divided into a head section 1, a transition section 3, a middle section 4, a feed inlet 6, and a tail section 7. A head wheel assembly is installed inside the head section 1, and a tail wheel assembly is installed inside the tail section 7. Scraper chains 5 are wound around the sprockets of the head wheel assembly and the tail wheel assembly. A drive device 2 is installed on the outside of the head section 1. The drive device 2 drives the head wheel assembly to rotate, and the sprocket in the head wheel assembly drives the scraper chain 5 to move, thereby realizing power transmission. The middle section 4 has a feed inlet 6 at its top; the head section 1 has a discharge outlet at its bottom.

[0024] like Figures 2-4 As shown, the middle section 4 includes a cover plate 41, an irregular side plate 42, an upper guide rail 43, an upper guide rail support plate 44, a side plate heat dissipation plate 45, a side liner plate 46, a heat-insulating lower guide rail 47, and a bottom plate 48.

[0025] The irregularly shaped side plate 42 includes a first L-shaped portion 42.1, a hypotenuse 42.2, a second L-shaped portion 42.3, and a third L-shaped portion 42.4. The first L-shaped portion 42.1, hypotenuse 42.2, second L-shaped portion 42.3, and third L-shaped portion 42.4 are bent sequentially from top to bottom to form a whole. The horizontal section of the uppermost first L-shaped portion 42.1 faces upward and outward, and the vertical section of the L-shaped portion connects to the hypotenuse 42.2, which faces inward and downward. The lower end of the hypotenuse 42.2 connects to the vertical section of the second L-shaped portion 42.3, and the horizontal section of the second L-shaped portion 42.3 faces outward and connects to the vertical section of the third L-shaped portion 42.4, which faces downward and outward.

[0026] The upper guide rail 43 is welded to the upper guide rail support plate 44, which is arranged in multiple groups at intervals on the upper end of the inclined side of the irregular side plate 42. The side plate heat dissipation plate 45 is arranged in multiple groups at intervals on the inner side of the irregular side plate 42. The side liner plate 46 is located on the short side of the right-angled trapezoidal portion of the irregular side plate 42. The upper guide rail support plate 44, the side plate heat dissipation plate 45 are perpendicular to the irregular side plate 42, and the side liner plate 46 is attached to the short side of the irregular side plate 42. The upper guide rail support plate 44, the side plate heat dissipation plate 45, the side liner plate 46, and the irregular side plate 42 are all welded together.

[0027] By using the side heat dissipation plate 45, the heat of the material 8 can be dissipated.

[0028] The upper end of the irregular side plate 42 is bolted to the cover plate 41, and the lower end of the irregular side plate 42 is bolted to the bottom plate 48.

[0029] like Figures 5-6 As shown, the heat-insulating lower guide rail 47 is welded and fixed to the base plate 48. The heat-insulating lower guide rail 47 includes a lower guide rail 81, which is mounted on an inverted U-shaped support plate 82. The lower side of the inverted U-shaped support plate 82 has spaced cutouts, and a heat-insulating gasket 83 is installed inside the inverted U-shaped support plate 82. The heat-insulating gasket 83 is a ceramic fiber heat-insulating gasket.

[0030] Since the scraper chain 5 rests on the heat-insulated lower guide rail 47, the use of heat-insulating gaskets 83 prevents the heat from the material 8 from being rapidly transferred to the heat-insulated lower guide rail 47 and then to the scraper chain 5. The heat-insulating gaskets 83 effectively isolate heat from being transferred to the scraper chain 5, thereby indirectly reducing the temperature of the chain rod.

[0031] By setting slits on the inverted U-shaped support plate 82, the contact area between the inverted U-shaped support plate 82 and the base plate 48 can be reduced, thereby reducing the heat of the material transferred to the chain through the base plate. For example, for a 1-meter-long guide rail, the total length of the slits on the inverted U-shaped support plate 82 is 0.9 meters, and only a few support points can be retained, thus greatly reducing the contact area between the inverted U-shaped support plate 82 and the base plate 48.

[0032] like Figures 7-8 As shown, the scraper chain 5 includes a chain rod 51, a pin 52, a spacer ring 53, a connecting plate 54, and scrapers 55. The chain rod 51, the pin 52, and the connecting plate 54 are connected to form a conveyor chain. Scrapers 55 are welded between the connecting plates 54 of the two conveyor chains, and the scrapers 55 are arranged at intervals along the direction of the conveyor chain.

[0033] Preferably, the height of the upper and lower ends of the connecting plate 54 is greater than the height of the upper and lower edges of the chain rod 51, the lower end of the scraper 55 is flush with the connecting plate 54, and the upper end of the scraper 55 is lower than the upper end of the connecting plate 54. Thus, the connecting plate 54 can separate the conveyor chain from the scraper 55.

[0034] Working principle and process: After passing through the feed port 6, material 8 falls into the rectangular space formed by the side liner 46, bottom plate 48, and connecting plate 54 of the scraper chain 5 in the unloaded section. The scraper 55 in the moving scraper chain 5 drives material 8 forward. Due to the isolation zone formed by the side liner 46 and connecting plate 54 in the intermediate section 4, material 8 cannot enter the space formed by the lower bend of the irregular side plate 42 and the bottom plate 48 in the intermediate section 4, thus achieving isolation between material 8 and chain rod 51. The ceramic fiber heat insulation pad 83 at the lower part of the heat-insulating lower guide rail 47 in the intermediate section 4 further reduces the heat conduction from material 8 to scraper chain 5 through bottom plate 48.
