Multiple perspectives to understand the various parts of the product
YJD-HX star unloader is suitable for powdery materials and granular materials. Widely used in environmental protection, metallurgy, chemical industry, food, food and other industrial sectors. It is the main equipment for dust removal, air supply and other equipment feeding. The structure is compact, the shape is beautiful, and the operation is convenient. Smooth running and low noise. Due to the bearing, the gear box is a distance away from the housing, and the lubrication is greatly improved for high temperatures.
Generally, the structure of the star-shaped unloader is composed of a rotor impeller with several blades, a casing, a seal, a reducer, and a motor. When the material in the upper silo falls by its own weight and fills the gap between the blades, the upper part is discharged with the rotation of the blades. Therefore, the star-shaped unloader can discharge quantitatively and continuously.
The dust discharge device is divided into a dry ash discharge device and a wet ash discharge device. Commonly used dry dust collectors are generally equipped with dry dust extraction devices.
(1) Dry ash discharge device
Dry ash discharge device is equipped for dry dust collector. Due to the negative pressure in the ash bucket of the dry dust collector, it must be kept closed during the ash discharge process, otherwise it will affect the dust removal efficiency. Generally, the dry type ash discharge device adopts double layers, because even if the structure is tight and the rotation is flexible, it will leak air. Experiments show that when the air leakage is 5%, the dust removal efficiency is reduced by 50%, and the purification efficiency will approach zero. For other> various dust collectors, the effect of air leakage on the purification efficiency is also very significant. The double-layer dry ash discharge device (double-layer heavy vertical air-locking ash discharge valve) opens and closes the upper and lower valve plates in turn. When the upper valve discharges ash, the lower valve closes. After a certain period of time, the lower valve discharges and the upper valve closes This will prevent air leaks.
The dust collected by the dry dust removal equipment must be recycled in a dry state or the dust that is transported and processed by a dry method should be used in a dry manner.
There are many types of dry ash discharge devices including manual plug-in valve, mechanical ash discharge valve and electric type. The manual plug valve is located in the lower part of the dust collector of the dust collector, and the gate valve is regularly opened manually to discharge dust. This kind of device not only has poor operating conditions, but also leaks air during ash discharge. The operating conditions are extremely bad. Manual plug-in valve devices are close to being eliminated. Currently, more mechanical bleed valves and electric plug-in valve ash discharge devices are used.
The dry ash discharge device can be divided into a flap type ash discharge valve, a conical flash valve, a tongue plate type dust discharge valve, a spiral ash remover, a manual insert valve, a star discharger, a rotary ash discharger, and an ash truck. .
(2) Wet dust extraction device
Wet dust extraction device is suitable for wet dust collectors and dry dust collectors with hydraulic dust extraction. Its role is to form a certain height of tight water seals and to remove mud dust. In cold areas or outdoors, anti-freezing measures should be considered.
Wet dust extraction device can be divided into full-flow dust discharge pipe, conical water seal slurry discharger, water seal ash flusher, water seal slurry discharge box, water seal slurry discharge, water flush dust discharge valve, dustpan dust discharge Valve, etc.
In addition, our company can install dust humidifiers (dust humidifiers) for dry dust collectors according to the requirements of customers. The dust humidifier can humidify and dry the dry dust and then discharge it to avoid secondary dust.
