With the development of exploration of American western oil, heavy oil more and more is found. These blocks of heavy oil because of high viscosity, cannot use the conventional mining methods, Brant screen emerge as the times require. The Brant screen functions are designed to separation of heavy oil, so oil smoothly through the mining screen screen, is the very essential for heavy oil recovery. Processing method of ordinary roughly are like the following: strengthen the soot blowing, keep heating surface clean; adjust the pressure and temperature of heavy oil, the maximum dilution, easy extraction. In addition, there are using new materials such as screen, nano materials. But the effect is not very good.
Brant screen can solve all the problems. As everyone knows, the main factors affecting the extraction ability of heavy oil is the screen mesh size, screen mesh is greater, the more easily through the heavy oil. The main factors affecting the screen mesh is arranged wire texture, texture sparse, screen space becomes larger. Therefore, Brant screen by increasing the wire mesh layer, reduce the wire mesh density, to achieve this effect. Generally speaking, brant screen is divided into two kinds: brant plate vibrating screen and brant layout of vibration screen.
Brant plate vibrating screen is one of the most common early oil vibration screen, and can be widely applied to different conditions in drilling operations. The goods are generally consists of 2 to 3 layers of stainless steel wire cloth adhesive in the opening of the metal lining plate together constitute, broken screen by the special rubber plug to repair the net surface, can effectively save time, reduce the cost of production.
Brant layout of vibration screen is a kind of common oil vibration sieve, mainly consists of steel layout and close contact in the frame of 2 to 3 layers. The frame of stainless steel mesh cloth frame made of high strength square steel or flat steel welded together, and with a plurality of reinforcing support ribs, net cloth through the metal lining plate and the distribution of contact, or direct bonding in the layout. Each screen are damaged by rubber stopper dedicated to repair the net surface.
In addition, the brant screen has been developing so far which has been also derived from the wave type vibrating screen and the frame vibration screen. Wave type vibration screen mesh is unique wavy, installation mode is wedge pressing device of crochet or steel frame net. Effective filtration area of wave network of the same specifications of flat net 125% to 150%, thus greatly improve the treatment capacity. Our factory can wave type screen manufacturing a variety of sizes according to customer requirements. Frame vibration sieve is a kind of common oil vibration sieve, is mainly composed of a steel frame and combined with 2 to 3 layers on the frame. The frame is made of high strength stainless steel wire mesh frame of square steel or flat steel welded together, and with a plurality of reinforcing support ribs, net cloth through the metal lining combined with the board and the frame, or direct bonding in the frame. Each screen is supplied with a rubber stopper dedicated to repair the net surface damage. Steel frame screen of our factory can manufacture various specifications according to customer requirements.
