A type of buried scraper conveyor housing

Abstract

This utility model relates to the technical field of buried scraper conveyors, specifically a buried scraper conveyor housing, including a shell, side wall microcrystalline stone plates, and a bottom microcrystalline stone plate. Side wall microcrystalline stone plates are provided on both sides of the shell, and a bottom microcrystalline stone plate is bonded between the side wall microcrystalline stone plates within the shell. The wear-resistant and corrosion-resistant microcrystalline stone plates prevent direct contact between the medium and the steel plate of the housing, eliminating the possibility of powder leakage due to friction and corrosion thinning of the steel plate. This eliminates the need for extensive welding of steel plates for leak sealing, and the steel plate does not directly contact the scraper chain or coal powder. Ordinary steel plates can be used for the shell to meet the requirements.

Description

Technical Field

[0001] This utility model relates to the technical field of buried scraper coal conveyors, specifically to a housing for a buried scraper coal conveyor. Background Technology

[0002] The buried scraper conveyor relies on the internal friction and lateral pressure of the material. During the material conveying process, the pressure in the direction of the scraper chain movement and the pushing force of the lower material on the upper material when continuously feeding are sufficient to overcome the external friction resistance generated between the material and the shell when the material is conveyed in the trough and the weight of the material itself. This allows the material to form a continuous flow and move forward, whether it is horizontal, inclined or vertical conveying. Generally, the housing of the buried scraper conveyor is made directly from steel plates for production.

[0003] Currently, when using buried scraper conveyor housings, the internal scraper chain and coal dust come into direct contact with the housing during operation. Through friction and corrosion, the steel plates of the housing become thinner, frequently leading to coal dust leaks. Furthermore, welding the steel plates to plug leaks is ineffective due to the thinness of the plates, resulting in only temporary treatment of the leak points, which cannot be completely eliminated. Therefore, a buried scraper conveyor housing design is proposed, which utilizes the method of attaching microcrystalline stone plates to avoid direct contact between the medium and the housing steel plates, preventing coal dust leakage caused by the steel plates thinning due to friction and corrosion, thereby improving the performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a buried scraper conveyor housing, which avoids direct contact between the medium and the steel plate of the housing, and prevents the steel plate from thinning and leaking powder due to friction and corrosion, thereby improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a buried scraper coal conveyor box body, including a shell, side wall microcrystalline stone plates and a bottom plate microcrystalline stone plate. Side wall microcrystalline stone plates are provided on both sides inside the shell, and a bottom plate microcrystalline stone plate is bonded between the side wall microcrystalline stone plates inside the shell.

[0006] By adopting the above technical solution, wear-resistant and corrosion-resistant microcrystalline stone plates can be used to avoid direct contact between the medium and the steel plate of the box, thus eliminating the situation where the steel plate becomes thinner and leaks powder due to friction and corrosion.

[0007] Specifically, the housing includes a first sidewall and a second sidewall, a bottom plate is provided between the first sidewall and the second sidewall, and a partition plate is provided on the top of the bottom plate.

[0008] Specifically, an adhesive layer is provided between the side wall microcrystalline stone plate and the bottom plate microcrystalline stone plate and the shell.

[0009] Specifically, connecting flanges are provided between the first sidewall, the second sidewall, and the bottom plate.

[0010] Specifically, a sealing gasket is provided between the housings.

[0011] The beneficial effects of this utility model are:

[0012] (1) The buried scraper coal conveyor box body of this utility model, through the setting of shell, side wall microcrystalline stone plate, and bottom plate microcrystalline stone plate, can avoid direct contact between the medium and the steel plate of the box body by using wear-resistant and corrosion-resistant microcrystalline stone plate, and eliminate the situation that the steel plate becomes thin and leaks powder due to friction and corrosion. There is no need to spend a lot of time welding steel plate to plug the leak. The steel plate will not come into direct contact with the scraper chain and coal powder. Ordinary steel plate can meet the requirements for the shell body.

[0013] (2) The buried scraper coal conveyor box of this utility model can be divided into three parts by setting the shell, the first side wall, the second side wall and the bottom plate, and become a split-combination shell. It can be assembled first and then installed, or the side wall can be installed first and then the bottom plate. The split structure makes it convenient to carry out effective construction in places where the space height is not suitable for overall installation, and the installation is more flexible and convenient.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] To avoid direct contact between the medium and the steel plate of the tank, and to prevent the steel plate from thinning and leaking powder due to friction and corrosion, thus improving the performance, such as... Figure 1-2 As shown, the present invention provides a buried scraper conveyor housing, comprising a shell 1, side wall microcrystalline stone plates 2, and bottom plate microcrystalline stone plates 3. Side wall microcrystalline stone plates 2 are provided on both sides of the shell 1, and bottom plate microcrystalline stone plates 3 are bonded between the side wall microcrystalline stone plates 2 inside the shell 1.

[0020] During use, the wear-resistant and corrosion-resistant microcrystalline stone slabs prevent direct contact between the medium and the steel plate of the tank, thus eliminating the possibility of powder leakage due to friction, corrosion, and thinning of the steel plate.

[0021] The casing 1 is U-shaped.

[0022] To improve ease of assembly and use, for example, such as Figure 1 , Figure 2 As shown, the present invention also includes a housing 1 comprising a first sidewall 101 and a second sidewall 102, a bottom plate 103 disposed between the first sidewall 101 and the second sidewall 102, and a partition plate 104 disposed on the top of the bottom plate 103.

[0023] In use, the first side wall 101, the second side wall 102, the base plate 103 and the partition plate 104 enable the modular structure to facilitate effective construction in places where the height is not suitable for overall installation.

[0024] For example, such as Figure 2 As shown, the present invention also includes an adhesive layer 4 between the side wall microcrystalline stone plate 2 and the bottom plate microcrystalline stone plate 3 and the shell 1.

[0025] In use, the adhesive layer 4 facilitates the bonding of the microcrystalline stone slab to the housing 1. The adhesive layer 4 is made of epoxy resin adhesive.

[0026] For example, such as Figure 2 As shown, the present invention also includes connecting flanges 5 provided between the first sidewall 101, the second sidewall 102 and the bottom plate 103.

[0027] In use, the first side wall 101, the second side wall 102 and the base plate 103 can be fixedly connected to each other by connecting flange 5. The boxes are connected to each other and to the unremoved parts by flanges and fixed with bolts.

[0028] For example, such as Figure 1 As shown, the present invention also includes a sealing gasket 6 disposed between the housings 1.

[0029] During use, the sealing gasket 6 facilitates sealing between flanges to prevent leakage at the connection. The sealing gasket 6 is made of nitrile rubber.

[0030] In use, the direct contact surface between the scraper chain and the coal powder is changed to the wear-resistant and corrosion-resistant side wall microcrystalline stone plate 2 and bottom plate microcrystalline stone plate 3, which avoids direct contact between the medium and the steel plate of the shell 1, and eliminates the situation where the steel plate becomes thin and leaks powder due to friction and corrosion. It eliminates the need to spend a lot of time welding steel plates to plug leaks, and the steel plate will not come into direct contact with the scraper chain and coal powder. Ordinary steel plates can be used for the shell 1 to meet the requirements. When the microcrystalline stone plate is worn or damaged in large quantities, it is only necessary to remove the problematic microcrystalline stone plate and replace it with a new one.

[0031] During installation, steel plates are used to divide the first side wall 101, the second side wall 102, and the base plate 103 into a grid. After applying adhesive to the housing 1, the microcrystalline stone panels 2 on the side wall and the microcrystalline stone panels 3 on the base plate are installed in the corresponding grids. This ensures that the microcrystalline stone panels will not move left or right during equipment operation, making the installation more secure. Moreover, the modular structure of the first side wall 101, the second side wall 102, and the base plate 103 allows for assembly before installation, or installation of the side wall first and then the base plate. The modular structure facilitates effective construction in places where the height is not suitable for integral installation, making it more flexible and stable to use.
