RLZ vacuum powder suction machine

The working principle of vacuum powder suction machine: Powder suction machines often use the method of vacuum material suction. The working principle of vacuum powder suction is to create a certain negative pressure in the hopper cavity, which causes the material to be sucked into the hopper

Working principle of vacuum powder suction machine

Vacuum suction is commonly used in powder suction machines, and the working principle of vacuum suction is to create a certain negative pressure in the hopper cavity to suck the material into the hopper.

The working process of the fully automatic microcomputer vacuum suction machine is as follows: when there is a shortage of material in the hopper, the contact switch that detects the material sends a signal to the microcomputer of the suction machine. The microcomputer then sends a signal to start the motor for vacuum suction. When the closed system reaches a certain degree of vacuum, it starts to suction the material. After the suction is completed, the material is discharged into the hopper. After a certain preparation time, the next cycle process is carried out.

When the hopper is full of material, the contact switch that detects the material will give a signal, and the powder suction action will be terminated.

During this cyclic process, ensure that the materials always meet the material requirements of the equipment.

Vacuum powder suction machine

The system consists of a vacuum pump (oil-free, waterless), stainless steel suction nozzle, conveying hose, PE filter (or 316L stainless steel filter), compressed air blowback device, pneumatic discharge door device, vacuum hopper, and material level automatic control device. The entire system is designed reasonably and manufactured beautifully.

Vacuum powder suction machines are divided into two types: gap discharge and continuous discharge. Gap discharge is beneficial for reducing equipment investment costs and facilitating material level control. In most cases, we recommend users to use gap discharge. Continuous discharge is generally used for vacuum conveying of materials over long distances and large production volumes.

Application of powder suction machine

For a long time, the transportation of powder materials between various production stages of vacuum feeders has become an important issue in improving production processes and enhancing product quality in the solid dosage form production process of the pharmaceutical industry.

In solid dosage form production enterprises in China, the production methods of manual batching and manual feeding are commonly used.

There are many types of materials that can be transported, including various loose materials, as well as small individual items such as cardboard boxes and packaging bags. The line is suitable for a wide range of applications. Firstly, the quality of the preparation work for the conveyor directly affects the installation quality and speed of the feeding machine.

Vacuum powder suction machineUsage and precautions

The main unit and hopper of the split type powder suction machine are designed separately, which is safe and convenient. The independent filtering device is easy to remove accumulated dust.
Installation of 1:3 split type powder suction machine with exhaust duct and independent powder suction machine. The independent powder suction machine has a small volume and light weight, and can be directly placed on a dryer or other raw material container to complete automatic powder suction. During use, the front suction nozzle (powder gun) of the powder suction port should be inserted into the material box by 20-50cm. When the material in the material box is used up and the powder suction machine cannot suck up the material, the powder suction machine will sound a no material alarm, and the powder suction operation should be stopped at this time. When the material box is filled with material, restart the powder suction operation.
When the material in the material box can be sucked, but the powder suction machine still sounds an alarm, the machine should be stopped immediately, the power should be turned off, the motor should be checked for overload, and the fault should be eliminated before proceeding with the powder suction operation. The powder suction machine should be cleaned regularly. First, stop the operation of the powder suction machine, then remove the filter cover, take off the filter, gently shake the filter, shake off dust and dirt, wipe it with clean cotton yarn, and then assemble it
