Description

Technical Field

[0001] The utility model relates to the field of conveying equipment. Background Art

[0002] Chain conveyor equipment is a common conveying equipment, for example, the public document with announcement number CN109383987A, publication date 2019-02-26, and patent name "Chain conveyor and drive sprocket for chain conveyor", discloses a conveyor assembly including multiple chains and multiple scrapers, each chain defines a longitudinal axis, and multiple scrapers are connected to the chain and configured to contact and move materials in a direction parallel to the longitudinal axis. Each of the multiple scrapers extends along a central axis, and the central axis is oriented obliquely relative to the longitudinal axis. Each scraper includes a first portion offset relative to a second portion in a direction parallel to the longitudinal axis.

[0003] When the MSR chain conveyor currently in use is in normal operation, if the production output is normal, the flue gas particulate content and materials will naturally fall to the bottom plate of the sprocket chamber. These fallen objects form a natural sprocket buffer layer, reducing the hard friction between the chain and the bottom plate. However, in current production, the equipment is configured with the maximum conveying capacity. When the material is small, the chain is in direct contact with the bottom of the shell, causing hard friction, resulting in severe wear of the contact surface between the chain and the shell and loud noise. For example, the MSR chain conveyor at the bottom of the boiler dust collector of the cement kiln low-temperature waste heat power generation system needs to replace the worn chain many times during operation, and the noise does not meet the standard. Summary of the invention

[0004] The technical problem to be solved by the utility model is to realize a chain conveying equipment frame structure which can reduce chain wear and reduce working noise.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a chain conveyor equipment bracket with wear-resistant and noise-reducing functions, the bracket is provided with a strip bottom plate, side plates are provided on both sides of the bottom plate, and multiple wheel frames are provided along the side plates, each of the wheel frames is provided with a sprocket fixed on it, all the sprockets are used to support the chain of the chain conveyor equipment, and a strip gasket is provided on the bottom plate directly below the chain.

[0006] The width of the gasket is smaller than the distance between the chain plates on both sides of the chain, and the thickness is greater than the distance between the chain pin and the edge of the chain plate.

[0007] The gasket is formed by continuously splicing a plurality of strip-shaped rubber strips, and mounting screw holes are reserved on the bottom plate. Each gasket is fixed in the screw hole of the bottom plate by at least two screws.

[0008] The gasket is a gasket made of rubber material.

[0009] Support plates for supporting upper chains are arranged between adjacent wheel frames, both ends of the support plates are fixed on the side plates, and the upper eaves of all the support plates have the same height.

[0010] A layer of rubber pad is fixed on the upper edge of each support plate.

[0011] The upper surfaces of the rubber pad and the gasket are smooth planes.

[0012] The utility model has the advantages that by installing the gasket on the bottom plate, the gasket can effectively reduce the contact friction with the chain, changing the overall friction to local friction, reducing the wear of the chain and reducing the noise during operation.

[0018] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0019] The conventional chain conveyor equipment bracket has an overall strip-shaped structure. Side plates 1 are vertically arranged on both sides of the strip bottom plate 2. A channel for the chain to rotate is formed in the middle. A plurality of wheel frames 3 are provided on the extended side plates 1. The heights and spacings of the wheel frames 3 are generally the same. A sprocket 4 is fixed on each wheel frame 3. The chain is supported by these sprockets 4. The chain is generally long. The bottom of the lower chain will contact the bottom plate 2. The sprocket 4 at one end is connected to the output shaft of the motor as a power source, forming a conventional chain conveyor equipment bracket. Fly ash is generally accumulated at the bottom of the bracket. The amount of fly ash is due to the content of flue gas particles and the natural falling characteristics of the material. If the output is not saturated, the dust collection amount will fluctuate. However, the equipment configuration capacity is the maximum conveying capacity. When the material is small, the chain is in direct contact with the bottom of the shell and rubs hard, resulting in severe wear of the contact surface between the chain and the shell, and loud noise.

[0020] In order to solve the noise problem, a strip-shaped gasket 5 is provided on the bottom plate 2 directly below the chain. The gasket 5 is preferably made of rubber material and has a smooth upper surface. The width of the gasket 5 is less than the spacing between the chain plates on both sides of the chain, and the thickness is greater than the spacing between the chain pin and the edge of the chain plate. In this way, the gasket 5 supports the chain pin, and the chain plates on both sides of the chain will not contact the bottom plate 2, reducing friction. The wear-resistant strip is set to be detachable, and the surface has a certain degree of smoothness to reduce contact friction, change overall friction to local friction, reduce wear, and reduce noise. To facilitate replacement and installation, the gasket 5 is composed of multiple strip-shaped rubber strips continuously spliced ​​together, and mounting screw holes are reserved on the bottom plate 2. Each gasket 5 is fixed in the screw hole of the bottom plate 2 by at least two screws.

[0021] In addition, the upper chain may also sink, therefore, support plates for supporting the upper chain are provided between adjacent wheel frames 3, and the number of support plates needs to be set. Generally speaking, both ends of the support plates are fixed on the side plates 1, and the upper edges of the support plates are at the same height. Currently, the support plates are in hard contact with the chains, and there are also problems with noise and wear. Therefore, a layer of rubber pads can be fixed on the upper edges of each support plate. The rubber pads, like the gaskets 5, have a smooth upper surface, so that the upper chain support structure can also reduce contact friction, changing overall friction to local friction, reducing wear and reducing noise.

[0022] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
