Description

Novel vertical ball mill

Technical Field

The utility model relates to a ball mill technical field, concretely relates to novel vertical ball mill.

Background

The vertical ball mill is suitable for grinding and dispersing materials with thicker and harder particles or pseudo-thick particles, the materials ground by the vertical ball mill have uniform granularity and fine particles, the vertical ball mill can also mix a plurality of materials together very uniformly, and the working principle of the vertical ball mill is as follows: the stirring shaft is used for driving the grinding balls to perform a forced mechanical shearing and grinding effect, and the materials are conveyed to the upper opening of the grinding cylinder through a filter screen at the bottom of the grinding cylinder and a pipeline by a material pump so that the materials are fully contacted with a medium and ground, and one-time circulation is completed until the fineness requirement is met.

The main problems of the prior art neutral ball mill are:

(1) after the materials enter the ball mill, the materials with smaller fineness are generally deposited at the bottom, the materials with larger fineness are generally positioned at the upper part, the stirring paddle rotates on the transverse horizontal section, the coverage area is smaller, and the motion range of the grinding balls and the materials is driven to be limited, so that the materials are easy to grind unevenly.

(2) The stirring shaft is fixed in form, the motion track of the grinding balls under the rotation action of the stirring shaft is also certain, under the condition, common materials cannot be uniform, one part of the materials are better ground, the other part of the materials are poorer ground, the grinding is repeated for multiple times, the fineness of the materials can reach the standard, and the grinding period is relatively long.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel vertical ball mill, the (mixing) shaft oar type can change.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a novel vertical ball mill comprises a shell, wherein a feed inlet is formed in the top of the shell, a discharge outlet is formed in the bottom of the shell, an interlayer is arranged in the shell and used for introducing and discharging a cooling medium, a motor is arranged in the shell to drive a rotating stirring shaft, the stirring shaft comprises a main shaft, and a plurality of paddle discs are arranged on the main shaft along the axis; the axis of the paddle disk is used as the circle center, a plurality of paddle grooves are uniformly distributed, the paddles are connected with the paddle grooves through a rotating shaft, the paddles rotate along with the rotating shaft, the rotating shaft can rotate relative to the paddle grooves, one end of the rotating shaft extends into the paddle disk and is connected with a motor in the paddle disk, and the rotating shaft is driven by the motor to rotate.

Compared with the prior art, the utility model, following beneficial effect has:

the utility model discloses in, the paddle of the (mixing) shaft of ball mill can change the form at the rotation in-process to make the grinding ball carry out anomalous motion, the grinding ball mixes more evenly with the material, makes the grinding cycle shorten, and product quality is more stable.

Wherein the reference numerals are as follows: 1-shell, 2-stirring shaft, 3-grinding ball, 4-motor, 5-blade disc, 6-blade and 7-rotating shaft.

Detailed Description

The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.

Example 1

As shown in figure 1, the novel vertical ball mill comprises a shell 1, wherein a feed inlet is formed in the upper part of the shell 1, and a discharge outlet is formed in the bottom of the shell 1. The heat transfer interlayer is arranged in the shell 1 and used for leading in and leading out cooling medium.

The top of the shell 1 is provided with a motor 4 and a speed reducer, the output end of the motor 4 is connected with the speed reducer, the output end of the speed reducer is connected with a stirring shaft 2, and the stirring shaft 2 is positioned in the shell 1. A plurality of grinding balls 3 are arranged in the shell 1.

The ball mill of the present embodiment is different from the existing ball mill in that, as shown in fig. 2, the stirring shaft 2 includes a main shaft and a paddle disk 5 uniformly distributed along the main shaft axis, and the paddles 6 are uniformly distributed on the paddle disk 5 with the main shaft axis as the center.

The blade disc 5 is provided with a plurality of blade grooves around the axis, and the blade grooves correspond to the blades 6 one by one. One end of the paddle 6 is located in the paddle groove, the rotating shaft penetrates through the paddle 6, and the two ends of the rotating shaft penetrate through the wall of the paddle groove, so that the rotating shaft extends into the paddle disc 5.

Pivot 7 and paddle 6 fixed connection for paddle 6 follows pivot 7 and rotates, and 7 both ends of pivot are connected through the bearing with the paddle groove cell wall, are equipped with motor 4 in the paddle dish 5, and motor 4 passes through the gear drive structure and is connected with 7 one end of pivot, and motor 4 drives the axis of rotation and rotates. Thereby driving the blades 6 to rotate at an angle.

The working principle of the embodiment is as follows:

in the ball mill described in this embodiment, (mixing) shaft 2 is rotatory, it is rotatory to drive paddle 6 to drive the in-process of 3 abrasive material of grinding ball, the angle of paddle 6 can change, the form of paddle 6 can change promptly, just so drive grinding ball 3 and be an anomalous motion, the material mixes more evenly, the material does not pile up, levigate the material more easily, thereby reduced the grinding cycle, simultaneously because the motion is more irregular, the compounding is more even, the quality of product is more stable.

According to the above embodiment, alright realize the utility model discloses well. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
