[0002] The casing of a coal mill is the external structure of the equipment, which serves to enclose and support the internal components. The design of the casing usually takes into account factors such as the performance, safety, and durability of the equipment.

[0003] Previous casings lacked structures that could be easily reinforced, resulting in insufficient overall strength during use and making them prone to damage. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a high-strength housing for a coal mill, which has a structure that can be easily strengthened, resulting in higher overall strength and less susceptibility to damage during use.

[0005] The technical solution adopted by this utility model to solve its technical problem is a high-strength housing for a coal mill, including an upper housing, a lower housing, supporting feet and a water tank. The upper housing and the lower housing are respectively provided with a first connecting block and a second connecting block near each other. The first connecting block and the second connecting block are fastened together by connecting bolts.

[0006] The first connecting block and the second connecting block are both provided with positioning grooves. An annular vertical plate is inserted in the positioning groove. An annular mounting plate is connected to the inner side of the annular vertical plate through an annular horizontal plate. The annular mounting plate is located on the inner side of the inner wall of the upper shell and the lower shell. The inner wall of the annular mounting plate is provided with threaded holes.

[0007] By adopting the above technical solution, the first connecting block and the second connecting block are connected by connecting bolts, so that the positioning groove positions the annular vertical plate. Since the annular mounting plate is connected to the inner side of the annular vertical plate through the annular horizontal plate, and the annular mounting plate is attached to the inner wall of the upper and lower shells, a reinforcing structure can be added at the connection between the upper and lower shells through the annular mounting plate, the annular horizontal plate and the annular vertical plate. The machine shell has a structure that can be easily strengthened, and the overall strength during use is greatly improved and it is not easy to be damaged.

[0008] Specifically, the outer wall of the annular mounting plate is provided with a sealing ring through a slot, and the inner walls of the upper and lower housings are provided with sealing grooves at positions corresponding to the sealing rings, with the ends of the sealing rings being engaged in the corresponding sealing grooves.

[0009] Specifically, the inner wall of the annular mounting plate is provided with chamfers near the top and bottom edges.

[0010] Specifically, hollow heat-conducting shells are provided in the top of the upper shell and the bottom of the lower shell through mounting grooves. The top and bottom of the water tank are respectively connected to a first pipe and a second pipe, and the first pipe and the second pipe both lead into the corresponding hollow heat-conducting shells.

[0011] Specifically, a water pump is installed on the first pipeline, and a water inlet pipe is installed at one end of the top of the water tank through a reserved hole. A stopcock is installed on the inside of the water inlet pipe through an internal thread.

[0012] By adopting the above technical solution, the water pump can make the water circulate in the first pipe, the second pipe and the hollow heat-conducting shell, thereby effectively conducting heat and dissipating heat on the inner walls of the upper shell and the lower shell.

[0013] Specifically, support pads are provided at the bottom of the lower housing near the corners.

[0014] The beneficial effects of this utility model are:

[0015] The high-strength housing for a coal mill described in this utility model features an annular mounting plate connected to the inner side of an annular vertical plate via an annular horizontal plate. The annular mounting plate rests against the inner walls of the upper and lower housings. Through the annular mounting plate, the annular horizontal plate, and the annular vertical plate, a reinforcing structure can be added at the connection between the upper and lower housings. This housing has a structure that can be easily strengthened, resulting in a significantly improved overall strength during use and making it less prone to damage. Attached Figure Description

[0023] 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.

[0024] To ensure the casing has a structure that allows for easy reinforcement, thereby increasing overall strength during use and reducing the likelihood of damage, such as... Figure 1-5 As shown, the high-strength housing for a coal mill of this utility model includes an upper housing 1, a lower housing 2, a support foot pad 3, and a water tank 5. The upper housing 1 and the lower housing 2 are respectively provided with a first connecting block 11 and a second connecting block 12 near each other. The first connecting block 11 and the second connecting block 12 are fastened together by connecting bolts 13.

[0025] The first connecting block 11 and the second connecting block 12 are both provided with positioning grooves 21. An annular vertical plate 19 is inserted in the positioning groove 21. An annular mounting plate 14 is connected to the inner side of the annular vertical plate 19 through an annular horizontal plate 18. The annular mounting plate 14 is located on the inner side of the inner wall of the upper shell 1 and the lower shell 2. A threaded hole 22 is provided on the inner wall of the annular mounting plate 14.

[0026] In use, the first connecting block 11 and the second connecting block 12 are connected by connecting bolts 13, so that the positioning groove 21 positions the annular vertical plate 19. Since the annular mounting plate 14 is connected to the inner side of the annular vertical plate 19 through the annular horizontal plate 18, and the annular mounting plate 14 is attached to the inner wall of the upper housing 1 and the lower housing 2, a reinforcing structure can be added at the connection between the upper housing 1 and the lower housing 2 through the annular mounting plate 14, the annular horizontal plate 18 and the annular vertical plate 19. The housing has a structure that can be easily strengthened, and the overall strength during use is greatly improved, making it less prone to damage.

[0027] For example, such as Figure 4 and Figure 5 As shown, the present invention also includes a sealing ring 17 provided on the outer wall of the annular mounting plate 14 through a slot 16, and a sealing groove 20 provided on the inner wall of the upper shell 1 and the lower shell 2 at a position corresponding to the sealing ring 17, with the ends of the sealing ring 17 being engaged in the corresponding sealing groove 20.

[0028] In use, the sealing groove 20 cooperates with the sealing ring 17 to facilitate the improvement of the sealing effect between the annular mounting plate 14 and the inner walls of the upper housing 1 and the lower housing 2.

[0029] For example, such as Figure 1 , Figure 4 and Figure 5 As shown, the present invention also includes chamfered corners 15 on the inner wall of the annular mounting plate 14 near the top edge and the bottom edge.

[0030] During use, the chamfered corner 15 on the inner wall of the annular mounting plate 14 can effectively prevent the annular coal material from piling up on top of the annular mounting plate 14.

[0031] For example, such as Figure 1-3 As shown, the present invention also includes hollow heat-conducting shells 4 provided in the top of the upper shell 1 and the bottom of the lower shell 2 through mounting grooves. The top and bottom of the water tank 5 are respectively connected to a first pipe 8 and a second pipe 9, and the first pipe 8 and the second pipe 9 both lead into the corresponding hollow heat-conducting shells 4.

[0032] In use, the first pipe 8, the second pipe 9, and the hollow heat-conducting shell 4 facilitate heat conduction after water is filled in.

[0033] For example, such as Figure 1-3 As shown, the present invention also includes a water pump 10 installed on the first pipe 8, a water inlet pipe 6 installed at one end of the top of the water tank 5 through a reserved hole, and a stopcock 7 installed on the inner side of the water inlet pipe 6 through an internal thread.

[0034] During use, the water pump 10 can make the water circulate in the first pipe 8, the second pipe 9 and the hollow heat-conducting shell 4, thereby effectively conducting heat and dissipating heat on the inner walls of the upper shell 1 and the lower shell 2.

[0035] For example, such as Figure 1 As shown, the present invention also includes supporting feet 3 at the bottom of the lower housing 2 near the corners.

[0036] During use, the support feet 3 provide convenient support for the bottom of the lower housing 2.

[0037] In use, the first connecting block 11 and the second connecting block 12 are connected by connecting bolts 13, so that the positioning groove 21 positions the annular vertical plate 19. Since the annular mounting plate 14 is connected to the inner side of the annular vertical plate 19 by the annular horizontal plate 18, and the annular mounting plate 14 is attached to the inner wall of the upper shell 1 and the lower shell 2, a reinforcing structure can be added at the connection between the upper shell 1 and the lower shell 2 through the annular mounting plate 14, the annular horizontal plate 18 and the annular vertical plate 19. The machine shell has a structure that can be easily strengthened, and the overall strength during use is greatly improved and it is not easy to be damaged. The static ring component of the coal mill can be easily installed on the inner side of the annular mounting plate 14 by screws and threaded holes 22.

[0038] Both the upper shell 1 and the lower shell 2 are made of metal. When they come into contact with the coal raw material or the hot air inside the upper shell 1 and the lower shell 2, they can effectively conduct heat. By loosening the water pipe 6 in the stopcock 7, it is convenient to add water to the water tank 5 through the stopcock 7. The water pump 10 can make the water circulate in the first pipe 8, the second pipe 9 and the hollow heat-conducting shell 4, thereby effectively conducting heat and dissipating heat on the inner walls of the upper shell 1 and the lower shell 2.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
