How does the stone production line block dust pollution

Because of stone crusher is not fully closed, at work, being hit by extrusion, stone, stone clearance of air is extruded and high-speed outward movement, lead dust with escape, instantly raise large amounts of dust. The dusty air passes down through the chute (a few) or through the feeding mouth (most), causing a high concentration of dust around the feeding mouth. Being in this state for a long time will not only cause serious pollution to the environment, but also cause great harm to the human body. So how to control the dust pollution of the crusher, as a professional broken equipment manufacturer, which aspects should we improve?vacuum furnace

(1) close control will seal the dust source with a sealed cover to make the dust not spread widely.vacuum furnaces

(2) eliminate highly potential difference handling equipment hopper, shield, chute, etc for powder, high potential difference generated by the difference of the main causes of spillover is the dust float in the sky, try to reduce the gap, reduce the chute chute inclination, some secret chamber caused by negative pressure best closed, such ability for dust collection.

(3) the wet dust removal and exhaust dust removal according to the reasons of the dust, dust source can be set respectively control countermeasures: in the feeding mouth and tape transshipment point setting spray device, and to control the amount of water wet stone, can significantly reduce the crushing plant transfer point inside the dust pollution; When the reprint point, especially when the underground construction of the underground building is bad, the centrifugal fan should be used, the ventilation should be forced and the wind speed and air volume should be enhanced. When the dust is produced by the operation of the tape, the negative pressure control system of the cloth bag filter is adopted to control the dust source.

Analysis of the single crystal furnace furnace cover for profile

Analysis of the single crystal furnace furnace cover for profile

Single crystal furnace furnace cover is commonly oval head. Due to its good mechanical properties and processing technology. It is widely used in industry. In the production of single crystal furnace, often encountered in the welding ellipsoidal head to take over the problem. This kind of production enterprises in China are generally use manual and welding. The backward mode of processing not only processing efficiency is low, and the machining quality is difficult to meet the design requirements, the production efficiency and welding quality is affected.
Main components of the ellipsoidal head is half elliptical shell. Shell is limited by two surface objects, uniform shell thickness of each point in the midpoint of the curved surface is called shell surface, the surface formed by surface of revolution is called the revolving shell, the shell surface in the busbar rotary formed a revolving shell. Therefore, represented by an elliptical head surface in busbar elliptical head geometry.
Spread principle, the single crystal furnace general elliptical head takes over the shape of cylinder cover, the case is the top surface is divided into many small line segments, each segment and the adjacent two plain wire and nozzle-vessel junction line to form a quadrilateral, obtained the side length of each side of the quadrilateral can expand the quadrilateral, such one by one on all quadrilateral is the ellipse over expansion plan.
Surface is considered to be a move line in space motion trajectory, the line is called bus, bus bar in the surface in a position, known as plain wire. Available to take over the plain wire cylinder and elliptical head surface intersection; Then calculate the corresponding node. Point to the distance on the surface of the ellipse to take over the top is the prayer plain wire length.
General furnace cover elliptical head over the single crystal furnace is a common problem in practical production. We use parallel expansion method taking over a mathematical model is established, with the aid of computer promptly and accurately draw a diagram, fast and exact underground material, thus to take over the precast, slope and the curve of the head group H in uniform after clearance, improved the welding speed, improves the production efficiency and product quality.

The influencing factors of vacuum furnace temperature to transfer

The influencing factors of vacuum furnace temperature to transfer

1, the strength of the vacuum furnace heating element, in the design, mainly in the form of heat. Internal heat source heating, temperature, from inside to outside, the strength size directly affect the temperature distribution in the furnace. When the inner court, the higher, the higher the temperature of the a fixed-point, at the same time must be the bigger the temperature difference distribution area. So, in the actual production process, can control the surface of the furnace core through the load or furnace core power control furnace temperature distribution.
2, reaction material from the core of distance, when furnace core power must have, namely the strength of the internal heating element must have, the farther distance furnace core of reaction, the lower the temperature, may not be able to achieve the required temperature reaction, the closer distance furnace core, the higher the temperature, the reaction.
3, burden the better performance of radiator cooling performance of the furnace charge, internal heat loss, the faster the outward heat loss in the reaction of material very easily, cause a fixed temperature decrease. But if the cooling performance of the reaction is not good, is needed for the convergence of heat, allows heat to pass time lengthen, conducive to the material to absorb heat and reaction, raise the temperature of a fixed point. Reaction under the condition of high vacuum (pa) 4 ~ 13, reaction temperature 1200 ℃, temperature of furnace core will soon be able to achieve the required value, so the reaction time of depending on the thickness of the material, the reaction furnace core periphery thought furnace insulation layer in the distance. Can through the design of furnace size control power supply time.
