Description

TECHNICAL FIELD

[0001] The utility model relates to a sealed access hole for filling stirring barrel belongs to metallurgical industry filling stirring barrel equipment technical field. BACKGROUND

[0002] The filling stirring barrel mainly carries out pretreatment to filling cementing material and tailings, and makes the excitation powder, slag powder and tailings fully mix and be even through stirring, so that the role of filling material is played as much as possible, and necessary conditions for whether the uniaxial flexural and compressive strength of the final filling body is qualified are created.

[0003] Since the filling slurry concentration of the filling cementing material mixed with the tailings is 58%-60%, and the large-diameter aggregate exists in the tailings, the wear degree of the impeller and the shaft in the stirring barrel needs to be checked regularly, if the wear is serious, the impeller loses the stirring effect, and the impeller must be replaced. On the other hand, long-time filling operation causes the internal agglomeration of the stirring barrel to be serious, the effective space inside the stirring barrel is reduced, the slurry stirring time is reduced, the filling slurry cannot be fully mixed, the flexural and compressive strength of the filling body is reduced, and the mine production is restricted. The traditional method is to cut an opening on the stirring barrel body by using oxygen-acetylene cutting, the maintenance personnel enter the stirring barrel to carry out maintenance operation, and the gap is welded again after the maintenance is completed. This method is time-consuming and laborious, and the barrel body cannot be restored to the original state due to the arc shape, causing the stirring barrel to run and leak slurry, and increasing the labor of the workers. Therefore, it is necessary to seek a reasonable stirring barrel access hole. CONTENT OF THE UTILITY MODEL

[0006] A sealed access hole for filling stirring barrel, comprising a stirring barrel body and an impeller arranged in the stirring barrel body, further comprising a sealing steel plate, a channel steel, an access hole and a fixing bolt, the access hole is arranged on one side of the stirring barrel body, the channel steel is arranged around the access hole, and the sealing steel plate is fixedly connected with the channel steel and the stirring barrel body through the fixing bolt.

[0007] The size of the sealing steel plate matches the size of the access hole, and ceramic pieces are attached to the inner side of the sealing steel plate.

[0008] A sealing rubber pad is arranged between the sealing steel plate and the channel steel.

[0009] The sealing rubber pad between the sealing steel plate and the channel steel is butyl rubber.

[0010] The channel steel is arc-shaped and matches the stirring barrel body.

[0011] The maintenance access is a rectangular opening, the channel steel is four, the sealing steel plate is a rectangular steel plate, and the length and the size of the four channel steels and the sealing steel plate are matched with the maintenance access.

[0012] The utility model discloses the beneficial effect is: simple structure, convenient construction, high maintenance efficiency, more wear -resisting after sticking ceramic piece improves its service period, and the recovery is not tight after each maintenance caused by the stirring barrel body is arc-shaped, and the accidents such as slurry running and slurry leakage during production are solved.
