How to classify the mixed air valve of welding dust collector?

<p>In order to protect the welding <a href="https://www.draire.net/industrial-electrostatic-precipitator" target="_blank">dust collector</a>, when the high-temperature flue gas temperature of the system exceeds the temperature that the filter bag can bear, the mixed air valve is opened to absorb the cold air and reduce the flue gas temperature to protect the normal operation of the filter bag. But how to classify the mixed air valve of the welding dust collector?</p><p><br></p><p>Welding dust collector&nbsp;mixed air valve classification</p><p><br></p><p>The welding dust collector&nbsp;air valve is divided into butterfly valve and lift valve two kinds, each kind is divided into pneumatic and electric two kinds.</p><p><br></p><p>Welding dust collector&nbsp;butterfly type mixed air pneumatic push rod butterfly valve. The valve has novel design, flexible opening and closing, quick switching, small flow resistance coefficient and convenient operation and maintenance. The valve is equipped with pneumatic push rod as the drive, open and close quickly and smoothly, is a fast cutting equipment.</p><p><br></p><p>Welding dust collector&nbsp;type electric push rod butterfly valve. The valve has novel design, flexible opening and closing, quick switching, small flow resistance coefficient and convenient operation and maintenance. The valve is also equipped with automatic protection device of electric push rod, which will automatically stop working when the thrust exceeds the rated index to protect the whole machine from damage.</p><p><br></p><p>The mixed air valve of the welding dust collector is driven by electric push rod (or cylinder), and a signal device for detecting the temperature of flue gas is set up in the dust removal system to drive the electric push rod (or cylinder) drive device for opening and closing operation according to this signal.</p><p><br></p><p>The mixed air valve of the welding dust collector&nbsp;is fully closed and fully actuated.</p><p><br></p><p>Generally, there are two types of mixed air valve, butterfly valve and disc lifting valve.</p><p><br></p><p>Welding centralized purifier silo type pump classification</p><p><br></p><p>The welding concentrated purifier silo type pump is divided into pulse type, up type, down type and fluidized type according to the discharging mode. According to the arrangement mode is divided into single warehouse layout and double warehouse layout. Single warehouse layout of the warehouse pump each can feed individually or several at the same time, but each ash tube can only be used for a warehouse pump ash, double warehouse layout of the warehouse pump in and out of the material is alternating.</p><p><br></p><p>Pulsed pneumatic conveying bin pump is suitable for short distance conveying with high conveying concentration, low flow rate, small diameter and slight wear of ash conveying pipe.</p><p><br></p><p>The up-leading silo pump is more suitable for long-distance transportation, with low conveying concentration, good conveying stability, high flow rate and easy pipe wear.</p><p><br></p><p>Downdraw type pneumatic conveying silo pump is suitable for medium and short distance conveying with high conveying concentration and large output.</p><p><br></p><p>Fluidized silo pump is suitable for medium distance transportation with high conveying concentration, good flow condition and large output.</p><p><br></p><p>Welding centralized purifier silo type pump structure</p><p><br></p><p>Welding the structure of centralized purifier silo pump, which is composed of ash road, gas road, silo pump body and control parts. The outlet of fluidized silo type pump is located above the silo type pump. Its advantage is that the ash block will not cause the clogging of the silo pump. Fluidized silo pump adopts multi-layer canvas plate or pagoda-shaped porous steel plate structure. Compressed air enters the vaporization chamber at the bottom of the silo pump through the air control inlet valve, dust particles are fully wrapped by the compressed air through the fluidized plate in the silo pump, so that dust particles form a fluid nature of the "countercurrent body", so as to have good fluidity, it can transport the concentrated phase, so as to achieve the purpose of smooth transport.</p>
