Abstract
Description
Technical Field
[0001] This utility model relates to the field of flange technology, specifically to an adjustable sealing flange. Background Technology
[0002] This flange is used in coal crushers, roller screens, and the shaft outlet of the housing. Currently, coal crushers and roller screens are important equipment in the coal conveying system of thermal power plants. They pre-treat the coal entering the furnace, crushing and screening it into a certain particle size to reduce the amount of coal crushed by the coal mill. Their operation directly affects the safety and reliability of the coal conveying system, and even the stable operation of the coal production system of the thermal power unit. The existing coal crushers, roller screens, and shaft outlets are all made of ordinary iron plates drilled or directly welded to the housing, resulting in poor sealing at the shaft outlets of the coal crushers, roller screens, and housings, causing coal dust leakage and generating a lot of dust at the work site, which affects the environment and the health of the workers. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable sealing flange, which solves the problems of poor sealing, coal powder leakage, and excessive dust generation at the work site in existing coal crushers, roller screens, and shaft outlet parts.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable sealing flange, including a flange body, a sealing frame on one side of the flange body, a sealing groove on the inner side of the sealing frame, a stainless steel sheet in the sealing groove, and a sealing strip on the inner side of the stainless steel sheet.
[0005] Preferably, the outer wall of the sealing frame has several bolt holes with the same structure.
[0006] Preferably, the flange body has several flange mounting holes with the same structure.
[0007] This utility model provides an adjustable sealing flange, which has the following advantages: the sealing frame and sealing strip designed on the flange body effectively prevent the leakage of coal powder from the coal crusher, roller screen and the shaft outlet of the box, increases the sealing performance, greatly reduces the coal powder generated at the working site, reduces pollution and improves safety.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Please see Figure 1-2 This utility model provides a technical solution: an adjustable sealing flange, including a flange body 1, a sealing frame 2 on one side of the flange body 1, a sealing groove 6 on the inner side of the sealing frame 2, a stainless steel sheet 4 in the sealing groove 6, and a sealing strip 5 on the inner side of the stainless steel sheet 4.
[0013] During installation, bolts need to be inserted into the flange mounting hole 7, and then the bolts are used to fix it to the coal crusher, roller screen, and box outlet shaft. Installing the flange at this location is a conventional technical method, so there is no need to go into detail about the installation process and the bolt tightening method.
[0014] Furthermore, the outer wall of the sealing frame 2 is provided with several bolt holes 3 with the same structure.
[0015] Furthermore, the flange body 1 has several flange mounting holes 7 with the same structure.
[0016] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0017] Example: During use, the flange body 1 of the coal crusher, roller screen and box shaft outlet is equipped with a sealing frame and sealing strip, and a stainless steel sheet is provided in the sealing groove, which can ensure that coal powder cannot easily leak out through the flange body 1, and the sealing performance is strong.
[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
