Description

Technical Field

[0001] The utility model relates to the technical field of conveying mechanisms, in particular to a novel scraper conveying structure applied to dry sludge particles. Background Art

[0002] In the two-stage sludge drying process, after the sludge is dried, the dry sludge particles are transported to the silo through the scraper conveyor. During the transportation process, the dry sludge particles will corrode and wear the related parts of the scraper conveyor, such as the chain plates, rollers, axle pins, and guide rails of the scraper conveyor, which are easily corroded and worn; resulting in mechanical failures such as breakage or jamming of the scraper conveyor. Generally, the service life of the related parts of the scraper conveyor is about 2 years; seriously affecting the stable operation of production.

[0003] refer to Figure 1 The existing scraper conveyor structure consists of: a chain plate 1, a roller 2, a pin 3, a guide rail 4, a scraper 5 and a box 6. The chain plate 1, the roller 2, and the pin 3 form a conveying chain. The scraper 5 is welded on the chain plate 1, and the guide rail 4 is welded on the box. The conveying chain drives the scraper 5 to run on the guide rail 4 to transport the dry sludge particles in the box 6 to the silo.

[0004] The existing scraper conveyor device consists of a conveying chain consisting of a chain plate 1, a roller 2, and a pin 3. During the conveying operation in dry sludge, the chain plate 1, roller 2, and pin 3 of the scraper conveyor device are in contact with each other and rotate and wear, causing the chain plate 1 to wear and become larger and break; the inner hole and outer diameter of the roller 2 will wear and become smaller; the outer diameter of the pin 3 will be worn and become smaller; therefore, any damage to the conveyor chain will cause the chain to get stuck or break; the service life of the components of a general scraper conveyor device is about 2 years, which can be referred to Figure 2 As shown;

[0005] The guide rail 4 of the existing scraper conveyor is used for conveying in dry sludge. The guide rail 4 contacts the roller 2 and generates friction, which causes the guide rail 4 to be worn out and damaged. Figure 3 ;

[0006] In addition, the guide rails are welded to the box body, which makes them difficult to remove and replace. A cutting machine is required to cut the guide rails, making inspection and maintenance inconvenient.

[0007] Therefore, it is necessary to design a new scraper conveying structure for dry sludge particles to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a novel scraper conveying structure applied to dry sludge particles to overcome the above-mentioned shortcomings of the current prior art.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A new type of scraper conveying structure used for dry sludge particles includes a box body, and is characterized in that it also includes a pull rod type chain plate placed in the box body, and a plurality of scrapers welded to both sides of the pull rod type chain plate, and guide rail assemblies are respectively arranged at the bottom of the scrapers on both sides. The pull rod type chain plate includes a plurality of pull rods connected end to end, and a pin shaft for connecting the pull rods, and the guide rail assembly includes a guide rail slot and a marble guide rail laid on the guide rail slot.

[0011] Preferably, the pull rod includes a shaft body, a large C-shaped block and a small C-shaped block respectively arranged at both ends of the shaft body, and the large C-shaped block and the small C-shaped block are provided with hole grooves for matching pin shaft installation. The small C-shaped blocks of one group of pull rods are placed in the large C-shaped blocks of another group of pull rods and are arranged relative to each other.

[0012] Preferably, the marble guide rail is fixed and laid in the guide rail slot by glue, and the marble guide rail is made of marble.

[0013] The beneficial effects of the utility model are as follows: the technical scheme adopts a pull rod type chain plate, whose components consist of a pin shaft and a pull rod, and eliminates rollers. The material is made of stainless steel and is die-cast, thereby reducing the wear between the components of the scraper conveyor device and extending its service life. The guide rail is made of marble, which has the properties of high hardness and smooth surface. The marble guide rail is fixed by the stainless steel guide rail slot, and the pull rod chain drives the scraper to slide on the marble guide rail. The friction coefficient is small, thereby reducing the wear of the components of the scraper conveyor device and increasing the service life of the scraper conveyor device.
