Description

Pendant Hem Crusher

technical field

The invention relates to a pulverizer, in particular to a drooping up and down pulverizer.

Background technique

A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of pulverizing in the form of high-speed impact. Using wind energy to form powder at one time, canceling the traditional screening procedure. It is mainly used in mining, building materials and other industries.

According to the size of the crushed material or crushed material, the pulverizer can be divided into a coarse crusher, a medium crusher, a fine grinder, and an ultrafine grinder. the

There are four kinds of external forces applied to the solid during the crushing process: rolling, shearing, impact, and grinding. Rolling is mainly used for coarse and medium crushing, suitable for crushing hard materials and bulk materials; shearing is mainly used for fine crushing, suitable for crushing tough materials; impact is mainly used for medium crushing, fine grinding, ultrafine grinding, suitable for For the crushing of brittle materials; the grinding is mainly in fine grinding and ultra-fine grinding, suitable for the crushing of small pieces and fine particles.

In medical equipment, many traditional Chinese medicines need to be ground in the production of Chinese patent medicines. Among the existing grinding mills, the characteristic is that they can complete ultrafine pulverizers. The whole machine consists of a feeding hopper, a crushing chamber, a classification chamber, and a cyclone Filter, bag filter, induced draft fan and other components are integrated into one. Its mechanism is complicated, the production cost is high, the vibration is relatively large, and the crushing time is long. After comparative analysis of the factors causing the above reasons, it is found that since most motors are placed below and the crushing chamber is set above the motor, under the action of gravity, if the grinding tool does not move close to the crushing chamber, the crushing time will be shorter. In addition, due to the wear and tear of the grinding tool, the crushing effect can also be weakened.

Contents of the invention

The object of the present invention is to provide a pendant pulverizer which is easy to process, has short pulverization time, and is driven downward by a motor to increase the pulverization effect.

In order to achieve the above object, the technical solution adopted by the present invention is: a drooping up and down pulverizer, including a table-type operation platform, a feed bin and a crushing drive device arranged above the table-type operation platform, and the table-type operation platform runs through the A crushing bin is provided, and the side wall of the crushing bin is provided with a feeding through hole, and the feeding through hole is connected to the bottom of the feeding bin, and a grinding knife is arranged inside the grinding bin, and the grinding knife is connected to a motor The drive shaft, the motor drive shaft is connected to the crushing drive device; the end of the crushing bin far away from the desktop operating platform is also connected to a leaking screen device.

The crushing drive device includes a motor outer casing, a pneumatic telescopic device is installed on the inner wall of the motor outer casing, the output shaft of the pneumatic telescopic device is connected to a motor, and the motor drive shaft extends into the motor outer casing and Connect with the motor.

The outer wall of the motor outer casing is connected with a sealed metal tube, and the sealed metal tube is also connected with the upper surface of the desktop operation platform and runs through the desktop operation platform, the pneumatic expansion device is also connected with a pneumatic control line, and the motor is also connected There is a motor control line, the pneumatic control line and the motor control line both penetrate the motor outer casing and extend into the sealed metal tube, and both the pneumatic control line and the motor control line pass through the lower surface of the desktop operation platform, the pneumatic control line The control line and the motor control line are also connected with a controller.

The outer casing of the motor is welded to the outer wall of the feed bin.

A clutch hole is provided at a position close to the upper surface of the table-type operating platform in the feed bin, and a sliding clutch plate is inserted in the clutch hole.

The sieving device includes a sieve shell and a sieve arranged inside the sieve shell, and the end of the sieve device away from the crushing bin is also connected to a discharge port.

Based on the above content, we can see that the pendant type upper and lower pulverizer designed by the present invention is to put the motor on the top and the crushing chamber to the bottom, and the sharpening knife moves at a high speed in the crushing chamber to crush the medicine. In order to prevent the dead angle of grinding, the invention is specially designed with a pneumatic telescopic device, which can drive the motor to move up and down, so that the grinder can swing up and down in the crushing chamber, which can solve the problem of grinding dead angle.

In order to reduce the vibration, the present invention welds the outer casing of the motor and the outer wall of the feeding bin according to the principle of mechanics, so that all the devices above the table-type operation platform are integrated. Therefore, the vibration amplitude can be effectively reduced.

In addition, due to the tightness requirements of medical processing, the motor control line used for motor power supply control and the pneumatic control line of the pneumatic expansion device are specially treated, and a sealed metal tube is specially added to make the motor control line and pneumatic control line from the sealed The metal tube passes inside to reach the controller.

The sieving device and the crushing bin designed in the present invention can be separated. When coarser or finer granular materials are needed, the fine sieving device can be separated from the crushing bin, and the sieve in the sieving device can be replaced. That's it.

The invention has the advantages of simple processing, low production cost, short grinding and crushing time, small vibration, and can eliminate grinding dead angle.
