Three -phase biological logistics bed experimental device

The three -phase biological logistics bed is the biochemical reaction in the fluidized bed directly in the qi, liquid, and solidarity, and there is no additional oxygen equipment and decapyllar equipment. The biofilm on the surface of the carrier relies on the stirring of the gas, so that the particles are fiercely friction and fall off. The oxygen method has decompression to release --r oxygen and firing aeration of oxygen. Sometimes a small amount of carrier may be brought out of the bed, so there is usually a carrier (including sludge) backflow in the process.

1. Product introduction

The device is based on the actual object of the 750P tractor wiper system to fully display the structure and working process of the tractor wiper system.

It is suitable for the teaching needs of school theory and m--ntenance tr--ning for tractor wiper systems.

2. Functional characteristics

1. Real and running wiper system, fully display the composition of the wiper and cleaning system.

The wiper and cleaning files of the combination switch can be performed by the functions of wipering systems such as intermittent scraping, low -speed scraping, high -speed scraping, and cleaning scraping.

2. The panel adopts a ** aluminum -plastic plate with strike, pollution resistance, fire prevention, and moisture -proof, and spray primer p--nting by special crafts on the surface; school students can intuitively control the circuit diagram and real objects, understand and analyze the working principle of wiper and cleaning systems Essence

3. Detecting terminals are installed on the panel, which can directly detect the electrical signals of the circuit components of the wiper and cleaning system on the panel, such as resistance, voltage, current, frequency signals, etc.

4. The panel part uses a 1.5mm cold plate stamping and forming structure, which is beautiful in shape; the bottom part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop of about 40cm on the base of the teaching plate, which is convenient for placing. Data, light detection instruments, etc.

5. The work adopts a normal 220V AC power supply. The internal circuit transformer is transformed into a 12V DC power supply. No battery is required to reduce the trouble of charging. The 12V DC power supply has a short -circuit function.

6. Machinery assembly and fitter assembly virtual simulation software:

This software is developed based on Unity3D. It can choose level 6 image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, typical mechanical mechanisms (virtual disassembly of gasoline engine engines) The software is an overall software that cannot be separated by separate resources.

A. Turbine design and virtual disassembly interface can be selected from turbine sn--l pole cone gear reducer, second -level pilot gear reducer, conical cylindrical gear reducer, coaxial cylindrical gear reducer, cone gear reducer, first -class cylindrical, first -class cylindrical, Gear reducer.
