Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to an anti-floating chain device for scraper conveyors. Background Art

[0002] A scraper conveyor uses a scraper chain to pull and transport bulk materials within a trough. It can be used for both horizontal and inclined transport. The operating principle of a scraper conveyor is that an open chute serves as a support for coal, gangue, or other materials, while scrapers are attached to a chain (forming the scraper chain) as the traction element. When the conveyor head transmission unit is activated, it drives the sprocket on the conveyor head shaft to rotate, causing the scraper chain to circulate, moving the material along the chute until it is unloaded at the conveyor head. The scraper chain then loops around the sprocket in a stepless closed loop, completing the material conveyance.

[0003] Zinc smelting and roasting furnaces mainly produce materials containing metals such as zinc, copper, iron, and silver. The materials are transported through box-type scraper conveyors. During the daily operation of the scraper conveyor, the material often sits on the bottom, causing the chain inside the box to float, resulting in a decrease in material conveying capacity. In addition, due to the accumulation of materials inside the scraper conveyor box, the chain may break in severe cases.

DETAILED DESCRIPTION

[0022] The utility model will be further described in connection with the drawings and specific embodiment:

[0023] For example Figures 1 to 4As shown, a scraper conveyor anti-floating chain device includes a box body 1 and a conveying mechanism arranged inside the box body 1, a partition 2 is fixedly arranged inside the box body 1, and the internal space of the box body 1 is formed into an upper cavity 3 and a lower cavity 4 through the partition 2, an upper slide assembly is symmetrically arranged inside the upper cavity 3, and a lower slide assembly is symmetrically arranged inside the lower cavity 4. In this embodiment, the shell of the scraper conveyor is composed of a plurality of boxes 1 spliced ​​together, and two adjacent boxes 1 are bolted together. The box body 1 is a structure with a hollow interior and open at both ends, wherein the number of upper slide assemblies inside the upper cavity 3 is two, and the number of lower slide assemblies inside the lower cavity 4 is also two. The effect of preventing the scraper conveyor chain from floating is achieved by the action of the lower slide assembly. At the same time, under the action of the upper slide assembly, the direct wear on the box body 1 is reduced, and the box body 1 is prevented from being worn or worn through; and under the action of the upper slide assembly and the lower slide assembly, the scraper conveyor chain is also facilitated to operate.

[0024] The downlink assembly includes a downlink 5, a side slide 6, and a pressure plate 7. Both downlink 5 and side slide 6 are fixedly connected to the housing 1. The pressure plate 7 is fixedly mounted at the bottom of the partition 2 and corresponds to the downlink 5. In this embodiment, the downlink 5, side slide 6, and pressure plate 7 are all made of 65Mn steel plate. The downlink 5 and side slide 7 are welded to the housing 1. The lengths of the downlink 5 and side slide 6 are the same as the length of the housing 1. The height of the side slide 6 is 100 mm. During the floating process of the scraper conveyor chain, the pressure plate 7 can promptly press down the floating scraper conveyor chain.

[0025] The conveying mechanism includes a plurality of sequentially connected scraper assemblies, each comprising a scraper 16 and two chain links. The ends of the scraper 16 are connected to the two chain links, respectively. The chain links are slidably connected to the lower slideway 5 and the side slideway 6. In this embodiment, the chain links of the plurality of scraper assemblies are interconnected to form a scraper conveyor chain. The chain links are slidably connected to the lower slideway 5 and the side slideway 6, facilitating the operation of the scraper conveyor chain while preventing the scraper conveyor chain from directly contacting the box 1.

[0026] The upper slide assembly includes a lower slide 8 and a side slide 9. The lower slide 8 is fixed to the top of the partition 2, and the side slide 9 is fixed to the inner wall of the box 1. In this embodiment, the lower slide 8 and the side slide 9 are also made of 65Mn steel plate. The side slide 9 is welded to the box 1. The length of the lower slide 8 and the side slide 9 is the same as that of the box 1, and the height of the side slide 9 is also 100mm. The lower slide 8 and the side slide 9 ensure that the scraper conveyor chain does not directly contact the box 1 when operating in the upper chamber 3.

[0027] The first lower slide 5 is fixedly mounted on the top of the bottom plate of the housing 1, and the first side slide 6 is fixedly mounted on the inner side wall of the housing 1. Limit bars 10 are fixedly mounted on the top edges of both the first lower slide 5 and the second lower slide 8. In this embodiment, the limit bars 10 limit the chain links of the scraper assembly, thereby limiting the position of the scraper conveyor chain. The top of the limit bar 10 is higher than the top of the first lower slide 5 and the second lower slide 8, respectively, to ensure that the chain links of the scraper assembly are limited.

[0028] The chain link includes a chain rod 11, a pin sleeve 12, and a U-shaped seat 13. The ends of the chain rod 11 are fixedly connected to the pin sleeve 12 and the U-shaped seat 13, respectively. A pin 14 is provided on the U-shaped seat 13. Two adjacent chain links are connected via the pin sleeve 12 and the pin 14. In this embodiment, two adjacent chain links are connected via the pin sleeve 12 and the pin 14 to form a scraper conveyor chain. The pin sleeve 12 of one of the two adjacent chain links is rotatably mounted on the pin 14 of the other chain link.

[0029] Each end of the scraper 16 is connected to a connecting rod 15, one end of which is fixedly connected to the inner side of the U-shaped seat 13 of the chain link. The angle between the scraper 16 and the horizontal plane is 80 degrees. In this embodiment, the scraper 16 is bolted to the connecting rod 15, and the connecting rod 15 is welded to the U-shaped seat 13.

[0030] The chain link within the lower cavity 4 is located between the lower slideway 1 5 and the pressure plate 7. The bottom ends of the pressure plate 7 are both curved structures. The U-shaped seat 13 is slidably connected to the lower slideway 1 5 and the side slideway 1 6. The U-shaped seat 13 of the chain link within the upper cavity 3 is slidably connected to the lower slideway 2 8 and the side slideway 2 9. In this embodiment, the cooperation of the U-shaped seat 13 with the lower slideway 1 5 and the side slideway 1 6 enables the pressure plate 7 to press down the floating scraper conveyor chain in a timely manner. The cooperation of the U-shaped seat 13 with the lower slideway 2 8 and the side slideway 2 9 prevents direct contact between the U-shaped seat 13 and the box body 1, reducing direct wear on the box body 1 and preventing wear and tear on the scraper conveyor box body 1.

[0031] When the utility model is in use, when the scraper conveyor is running to convey materials and the scraper conveyor chain reciprocates in the upper cavity 3 and the lower cavity 4 of the box body 1, the chain links of the scraper assembly of the conveying mechanism drive the scraper 16 to operate, thereby realizing the function of conveying materials; the U-shaped seat 13 of the scraper assembly chain link slides on the lower slide 5 and the side slide 1 6, the lower slide 2 8 and the side slide 2 9 respectively, and the U-shaped seat 13 does not directly contact the inner wall of the box body 1, thereby reducing the direct wear on the box body 1; and when the material sinks to the bottom and the scraper conveyor chain floats, the pressure plate 7 will press down the scraper conveyor chain in the floating process in time to ensure that the scraper conveyor chain is stable during the operation process and the chain does not float.

[0032] The above-described embodiments are merely preferred embodiments of the utility model, and are not intended to limit the utility model implementation scope. Therefore, equivalent changes or modifications made in accordance with the technical solutions described in the utility model patent scope should be included in the utility model application patent scope.
