Description

Technical Field

[0001] The utility model relates to the technical field of slag buckets, and more specifically to a simple self-unloading slag bucket for a ball mill. Background Art

[0002] The grate ball mill is a key equipment for crushing materials after they are broken. Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries to dry or wet grind various ores and other grindable materials. Since the grate ball mill will produce a part of raw ore with larger particle size during the grinding process, it needs to be returned to the ball mill for re-grinding. The usual method is to use the slag bucket to hold the large-particle raw ore, and then use the lifting equipment to lift it and transport it to the lower ore hopper of the ball mill.

[0003] The existing slag bucket for ball mill is generally provided with a movable door at the bottom of the slag bucket, and the hook at the movable door is locked by a fixing pin, and then the slag bucket is filled with materials. When the slag bucket filled with materials is transported to the lower mining funnel, the fixing pin is manually broken to unload the materials. However, this slag bucket has the following disadvantages during use:

[0004] 1. When hammering the fixing pins at the bottom of the slag bucket, part of the material in the slag bucket sinks into the lower ore funnel, which makes the operation space for hammering the pins narrow, which may cause safety hazards. The operating tools may splash and hit the workers or pinch their arms.

[0005] 2. Since the material inside the hopper has a large weight, the hook is tightly connected under the action of gravity, which increases the difficulty for the staff to break open the fixing pin. Utility Model Content

[0006] The purpose of the utility model is to solve the above technical problems and provide a simple self-unloading slag bucket for a ball mill, which can improve the efficiency of slag bucket transportation and unloading through the function of automatic unloading of the slag bucket, and reduce unsafe factors in the unloading process.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical scheme: a simple self-unloading slag bucket for a ball mill, comprising a slag bucket body and a lower ore funnel, the upper and lower end surfaces of the slag bucket body are respectively provided with an upper opening and a lower opening, the left and right sides of the lower opening are hingedly connected with movable plates, and the outer sides of the two movable plates are installed with a control opening and closing mechanism.

[0008] Preferably, the control opening and closing mechanism includes a plurality of first limiting rings, two second limiting rings, two third limiting rings and a steel wire rope.

[0009] Furthermore, several of the first limiting rings are fixedly connected to the bottom of the movable plate, two of the second limiting rings are respectively fixedly connected to the front and rear sides of the upper opening, and two of the third limiting rings are respectively fixedly connected to the front and rear sides of the lower opening, and the several first limiting rings, two second limiting rings, and two third limiting rings are all movably connected to the wire rope.

[0010] In order to lift the two steel wire ropes at the same time and then control the test status of the two movable plates at the same time, as a preferred embodiment of the utility model for a simple self-unloading slag bucket for a ball mill, the upper ends of the two steel wire ropes are penetrated and connected with buckles.

[0011] In order to make the hopper body stuck in the opening of the ore lowering funnel, as a preferred embodiment of the utility model for a simple self-unloading hopper for a ball mill, the hopper body is in a prism shape with a larger upper part and a smaller lower part, and the width of the upper opening is greater than the width of the ore lowering funnel opening.

[0012] The beneficial effects of the utility model are as follows: the opening and closing of the slag bucket mainly depends on the interaction force between the steel wire rope and the movable plate at the bottom of the slag bucket. When the empty bucket is placed at the slag discharge port of the ball mill, the steel wire rope is not subjected to force, and the two movable plates press the ground by their own weight to achieve the closing effect. When the slag bucket is filled with slag from the ball mill, the steel wire rope is lifted upward, the steel wire rope contracts, and the two movable plates are tightened and closed. When the slag bucket is placed at the ore feeding port, the bottom of the slag bucket is suspended in the air, and under the action of the gravity of the slag, the two movable plates open to complete the ore unloading, thereby improving the efficiency of slag bucket transportation and unloading, and reducing unsafe factors in the manual unloading process.

They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0022] See also Figure 1-6 The utility model provides the following technical solutions: a simple self-unloading slag bucket for a ball mill comprises a slag bucket body 1, upper and lower end surfaces of the slag bucket body 1 are respectively provided with an upper opening 101 and a lower opening 102, the left and right sides of the lower opening 102 are hingedly connected with movable plates 103, the outer sides of the two movable plates 103 are respectively installed with a control opening and closing mechanism 2, the control opening and closing mechanism 2 comprises a plurality of first limiting rings 3, two second limiting rings 4, two third limiting rings 5 ​​and a steel wire rope 6, a plurality of first limiting rings 3 are fixedly connected to the bottom of the movable plate 103, the two second limiting rings 4 are respectively fixedly connected to the front and rear sides of the upper opening 101, the two third limiting rings 5 ​​are respectively fixedly connected to the front and rear sides of the lower opening 102, a plurality of first limiting rings 3, two second limiting rings 4, two third limiting rings 5 ​​are all movably connected with the steel wire rope 6.

[0023] In this embodiment: a steel wire rope 6 passes through the front second limiting ring 4, the front third limiting ring 5, the first limiting ring 3, the rear third limiting ring 5, and the rear second limiting ring 4 in sequence, and then the steel wire rope 6 is connected end to end. The two second limiting rings 4 and the two third limiting rings 5 ​​limit the position of the steel wire rope 6 outside the bucket body 1, thereby preventing the steel wire rope 6 from slipping off the outside of the bucket; a plurality of first limiting rings 3 are used to limit the position of the steel wire rope 6 outside the movable plate 103, thereby preventing the steel wire rope 6 from slipping off the bottom of the bucket; when the bucket containing materials is transported, since the crane lifts the two steel wire ropes 6 during transportation, the downward gravity of the bucket as a whole is in the opposite direction to the upward force of the steel wire rope 6, thereby driving the two movable plates 103 to close. When the bucket is in a fixed position, the force lifting the steel wire rope 6 upward is released, the steel wire rope 6 slides downward, and the two movable plates 103 are opened, thereby facilitating the automatic unloading of materials in the bucket.

[0024] As a technical optimization solution of the present invention, a buckle 7 is connected through the upper ends of the two steel wire ropes 6 .

[0025] In the present embodiment, each steel wire rope 6 is connected end to end, and the upper ends of the two steel wire ropes 6 are movably connected with the same buckle 7. When the sling and the buckle 7 are installed, the two steel wire ropes 6 can be lifted by one sling at the same time, so that the opening and closing states of the two movable plates 103 at the same time can be kept consistent.

[0026] As a technical optimization solution of the utility model, the hopper body 1 is in a prism shape with a larger upper portion and a smaller lower portion, and the width of the upper opening 101 is greater than the width of the opening of the lower ore funnel 8 .

[0027] In the present embodiment, the bucket body 1 is in the shape of a prism with a larger upper portion and a smaller lower portion. When the lower end of the bucket is placed in the ore lowering funnel 8, the middle portion of the bucket body 1 is stuck in the opening of the ore lowering funnel 8, thereby fixing the positions of the left and right sides of the bucket so that the steel wire ropes 6 on the front and rear sides of the bucket can move, thereby automatically controlling the opening and closing states of the two movable plates 103 through the steel wire ropes 6.

[0028] The working principle and use process of the utility model are as follows: when the empty slag bucket is placed at the slag discharge port of the ball mill, the wire rope 6 is not subjected to force, and the two movable plates 103 press the ground by their own weight to achieve the closing effect; when the slag bucket body 1 is filled with slag from the ball mill, the sling and the buckle 7 are installed and lifted upward, and the entire slag bucket is moved by the sling. At this time, the downward gravity of the entire slag bucket and the upward force of the wire rope 6 are in the opposite direction, thereby driving the two movable plates 103 to close; when the lower end of the slag bucket is placed in the ore lowering funnel 8, the middle position of the slag bucket body 1 is stuck at the opening of the ore lowering funnel 8, the force of lifting the wire rope 6 upward is released, the wire rope 6 slides downward, and the two movable plates 103 open, thereby automatically unloading the material in the slag bucket.

[0029] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
