Introduction of the dosing mixer device
The medicine adding mixer device is mainly used for mixing, dissolving, and storing various medicines in the water treatment project, and the medicine liquid is added to each additional point through a metering pump or a water injector. The shape of the dosing box is divided into square and round, and the material is polyethylene (PE). It is formed by rotomolding technology at one time. The upper part is preset with the installation position of the metering pump and the mixer.
Dosing Mixer Device has a compact structure, small size, corrosion resistance, low energy consumption, and convenient operation and maintenance. It has the functions of storing medicine, mixing and exporting, and can realize manual, automatic, remote, local, and other control methods.
The main structure of the dosing mixer device:
Dosing Mixer (Gearbox):
mixer (gearbox) Introduction in the dosing box device
The mixer is also called a gearbox. The common gearbox is a cycloidal gearbox. The cycloidal pinwheel gearbox is a novel transmission device that uses the planetary transmission principle of a small tooth difference. The cycloid gearbox is an important transmission component in the dosing mixer device.
Transmission principle of gearbox in the mixer device
The cycloid gearbox is a novel transmission device that adopts the principle of K-H-V planetary transmission with small tooth difference. The difference in the number of teeth between the sun gear (pin gear) Zz and the planet gear (cycloid wheel) ZB is 1, that is Zz-ZB = 1. A double eccentric sleeve with an offset of 180 ° is installed on the input shaft, and two roller bearings called rotor arms are installed on the eccentric sleeve to form an H mechanism. The center holes of the two cycloid wheels are the rotor bearings on the eccentric sleeve. The raceway and the cycloid wheel is meshed with a set of ring-shaped needle teeth on the true gear to form an internal meshing deceleration mechanism with a tooth difference of one tooth (to reduce friction, in a reducer with a small speed ratio, With a pin sleeve on the pin teeth). When the input shaft rotates one circle with eccentricity, because the characteristics of the tooth profile curve on the cycloid wheel are extremely restricted by the pin teeth on the pin gear, the movement of the cycloid wheel becomes a plane motion with both revolution and rotation. When rotating one revolution, the eccentric sleeve is also rotating one revolution, the cycloid wheel rotates through a tooth in the opposite direction to be decelerated, and then uses the W output mechanism to transfer the low-speed rotation motion of the cycloid wheel to the output shaft through the pin shaft. This results in lower output speed.
Its vertical dosing mixer adopts the principle of cycloid gear and planetary transmission. It is one of the most advanced transmission tools today. It has the characteristics of large button pitch, high transmission efficiency, high power, long life, low price, and never adding oil. It is the best supporting product of the environmental protection dosing device. The preset metering pump and mixer installation positions of the dosing box are not completely applicable to all brands and models of metering pumps and mixers. The specific installation needs to be made by the customer according to the actual situation. Adjust accordingly.

Gear reducer transmission process
The transmission process is as follows: a double eccentric sleeve with an offset of 180 ° is installed on the input shaft, and two roller bearings called turning arms are installed on the eccentric sleeve, forming the H mechanism and the center holes of the two cycloid wheels are eccentric The raceway of the arm bearing is set, and the cycloid wheel is meshed with a set of annularly arranged needle teeth on the true gear to form an internal meshing reduction mechanism with a tooth difference of one tooth (to reduce friction, the speed ratio In the small reducer, there is a pin sleeve on the pin teeth).
Reducer characteristics and structure
1. High-speed ratio and high efficiency
Single-stage transmission can achieve a reduction ratio of 1:87 and an efficiency of more than 90%. If the multi-stage transmission is used, the reduction ratio is greater.
2. Compact structure and small volume
Due to the principle of planetary transmission, the input shaft and the output shaft are on the same centerline, so that the model can obtain the smallest possible size.
3. Low noise and stable motion
Cycloid needle teeth have a large number of meshing teeth, a large overlap coefficient, and a mechanism that balances the machine parts, which minimizes vibration and noise.
4. Reliable use and long life
Because the main parts are made of high carbon chromium steel material, which is quenched to obtain high strength, and part of the transmission contact uses rolling friction, so it has a long service life.
5. Reasonable design and convenient maintenance
Easy to disassemble and install, the minimum number of parts and simple lubrication make the cycloid reducer deeply trusted by users.
