Description

Material Crusher

technical field

The invention relates to the technical field of material crushing equipment, in particular to a material crushing machine.

Background technique

At present, most of the traditional pulverizers on the market are horizontal pulverizers and lack the mechanism for separating coarse and fine materials. All materials are repeatedly crushed, which increases the workload of personnel and equipment, which is labor-intensive, time-consuming, inefficient, and high in power consumption; especially for some materials with high water content or bouncy materials, the situation is more serious, and often used in practical applications. If the screen is blocked or the machine is choked, the material is difficult to crush, and it is easy to cause the equipment to stop or even damage the equipment; this kind of material cannot be crushed with a jaw crusher or a wheel mill, and the material will be crushed. In the shape of a mud cake, the use of a hammer mill is likely to cause the material to stick to the fixed plate and cause the rotor to stall and stop.

The invention patent with the application number 201210456393.8 published on March 20, 2013 discloses a continuous vertical stirring pulverizer, which mainly consists of a geared motor, a coupling, an upper bearing, a lower bearing, a stirring shaft, a cylinder, and paddles It is composed of fixed disc, rotating paddle, fixed paddle and elastic damping device. The stirring shaft is installed in the upper and lower bearings on the cylinder, and the deceleration motor or hydraulic pressure is fixed on the extended upper end of the stirring shaft with a coupling. Motor, the inner section of the mixing shaft is a regular polyhedron shaft section, on which the paddle fixed discs are fixed evenly spaced from top to bottom, and the regular polyhedral discs of each paddle fixed disc The rotating paddles are evenly distributed on the top, and the wear-resistant liner is fixedly installed on the inner wall of the cylinder. The relative movement makes the material achieve the effect of stirring and mixing while crushing.

Its disadvantages are: 1) Lack of coarse and fine material separation mechanism. When returning and crushing materials that are difficult to crush at one time, repeated crushing of qualified materials will increase the burden on equipment, increase the workload of personnel, affect work efficiency and consume electricity Increase; 2) Cylindrical barrel structure, it is easy to cause the material to drop too fast, and it is difficult to fully crush the material.

Contents of the invention

The object of the present invention is to provide a material pulverizer which can not only realize the separation of coarse and fine materials while pulverizing, but also can limit the traveling speed of materials and have higher pulverization efficiency.

The technical solution adopted to achieve the object of the present invention is: a material pulverizer, including a casing, an inverted frustum-shaped rotating body and an inverted frustum-shaped filter support are arranged in the casing, and the rotating body is connected to the machine through the main shaft. The shell is movably connected, and fixed blades and movable blades are arranged on its peripheral side, the filter support is fixedly connected with the casing, and a funnel-shaped slag discharge hopper connected with the filter support is arranged at the bottom of the casing. A material feed port and a slag feed port are respectively arranged on the top of the shell, the slag material drop hopper communicates with the slag material feed port through a return pipe, and a finished product discharge port is provided at the lower part of the side wall of the casing.

The lower part of the main shaft protrudes from the rotating body, and the protruding part is provided with rotating blades.

The bottom plate of the casing is arranged obliquely.

The fixed blade is arranged horizontally on the rotating body, and the movable blade is arranged on the rotating body through a rotating shaft.

The two ends of the main shaft are respectively movably connected with the casing through shaft seats.

An induced draft fan is arranged on the return pipe.

There are multiple finished product outlets.

In the material pulverizer of the present invention, an inverted frustum-shaped rotary body and an inverted frustum-shaped filter support are arranged on the main shaft, fixed blades and movable blades are arranged around the rotary body, and the filter holes on the filter support are designed to crush Filter the finished crushed material that meets the requirements into the cavity formed by the filter support and the casing, and if the crush degree does not meet the requirements, it will go along the slope-shaped gap between the filter support and the rotating part. The downward movement continues to crush, reducing the resistance of the equipment, improving the efficiency of the equipment, and avoiding the return of the finished crushed material that meets the requirements and the slag that does not meet the requirements, reducing the unnecessary workload of equipment and personnel, and improving production efficiency; Compared with the straight cylindrical structure, on the one hand, the structure of the present invention has a certain inclination, which slows down the downward speed of the material and makes the material pulverize more fully; When the material in a certain crushing process moves to the lower gap, it can still maintain a certain density, so that the crushing efficiency of the lower material is higher and more sufficient, and it avoids that the crushed material of the traditional equipment reaches the lower part of the equipment, which is sparse and falls too fast. Without the effect of crushing, it effectively realizes the separation of coarse and fine materials while crushing, and can limit the speed of material travel, and the crushing efficiency is higher and more sufficient; the main shaft is provided with rotating blades, and the rotating blades Below the rotator, on the one hand, the material traveling to the bottom of the rotating body is further cut and crushed, and on the other hand, it has a stirring effect on the material, so that the slag that does not meet the requirements quickly enters the funnel, avoiding the situation of clogging and choking; The bottom of the casing is provided with a funnel-shaped slag discharge hopper connected to the filter support. The slag discharge hopper collects the unsatisfactory slag and transports it to the slag feed port through the return pipe for crushing again. The lower part of the side wall of the casing is provided with a finished product discharge port, which is convenient for collecting the finished crushed materials that meet the requirements, and the finished crushed materials can be quickly extracted through the induced draft fan and the pipeline; The collection efficiency of the finished crushed material is that the finished crushed material slides to the finished product outlet under the action of gravity, avoiding the accumulation of the finished crushed material in the equipment; the fixed blade is horizontally arranged on the rotating body, and the movable The blade is set on the rotating body through the rotating shaft, the fixed blade can forcefully cut the material, and the movable blade realizes impact crushing under the action of inertia, and by adjusting the rotating speed, the cutting density of the blade can be adjusted; the two ends of the main shaft Respectively through the flexible connection of the shaft seat and the casing, the stability of the main shaft is greatly enhanced and the crushing efficiency is improved; the return pipe is provided with an induced draft fan, which greatly improves the return efficiency and quickly disposes of unsuitable slag The material is returned to the slag material inlet to avoid the blockage of the return pipe caused by the slag material; by adopting multiple finished product outlets, the collection efficiency of the finished crushed material that meets the requirements is greatly improved, and the finished crushed material is prevented from accumulating in the pulverizer within the cavity. The invention provides a material pulverizer for material pulverization, which can not only realize the separation of coarse and fine materials while pulverizing, but also limit the traveling speed of materials and have higher pulverization efficiency.
