Abstract

The utility model discloses an oil liquid sweeping device, which comprises a gas supply line. The outlet of the gas supply line is connected with a flat nozzle. The oil liquid sweeping device is mainly used for sweeping the oil liquid on a running surface after cold rolling. High pressure gas is sprayed from the spout of the nozzle. The oil liquid on the running surface is blown to the end part of a cold roll, thus causing that the oil fluid of the end part of the roll surface rotating with high speed is swept back to an oil pool and the oil fluid on the running surface after cold rolling is greatly reduced, avoiding that products generate oil spots and smear during annealing technique, and guaranteeing the quality of products.

Description

The fluid blow device

Technical field

The utility model relates to a kind of fluid blow device, is specifically related to a kind of blow device that the cold-rolling mill roller is a fluid that purges.

Background technology

Aluminium processing and other non-ferrous metal processing industry, the quality of its product surface quality in the operation of rolling depends on that not only the roller that roller system of rolling mill is set is a processing quality, and depends on the pressure flow and the quality of ROLLING OIL in the operation of rolling.But ROLLING OIL liquid the rolled products surface floating the amount increase or exceed standard, be not only the waste that a kind of fluid consumption increases, the more important thing is that the fluid of product surface is known from experience the oil mark that directly causes product to produce, the defective defective of oil stain during technology annealing.All adopt the scraper-type edible vegetable oil device that an industrial felt work respectively is installed in the upper and lower backing roll transverse center of milling train position mostly for most aluminium processing or metal processing industry, so that the fluid body on backing roll surface is blocked the oil return pond, but because industrial felt contacts with the roll surface friction for a long time, very easily cause coming off of the fine suede of hair, bonding roll surface, plate face or scuffing roll surface oil film influence production board face quality.

The utility model content

The purpose of this utility model is to provide a kind of blow device that can effectively purge cold rolling back plate face fluid.

For achieving the above object, the utility model by the following technical solutions: the fluid blow device, comprise steam line, the outlet of steam line is connected with the nozzle of flat.

The cross section of described nozzle is fan-shaped, and its longitudinal section is trapezoidal, and the spout of nozzle is an arcwall face.

Described nozzle is two, is connected by a U-shaped pipeline between nozzle and the steam line, and two nozzles are connected to the both ends of U-shaped pipeline.

The spout end of described two adjacent inboards of nozzle is provided with directed piece.

Described steam line is provided with controlling valve.

The utility model is mainly used in the fluid that purges on the cold rolling plate face later, gases at high pressure are by the spout ejection of nozzle, the fluid of plate face is blown the end to cold roll, thereby making at a high speed, the fluid of the roll surface end of rotation is purged the oil return pond, fluid on the plate face of cold rolling back is significantly reduced, avoid product during technology annealing, to produce oil mark, oil stain, guaranteed the quality of product; The spout end of two adjacent inboards of nozzle is provided with directed piece, is in order to adjust the direction of air-flow, to guarantee that fluid is blown the two ends to cold roll; Controlling valve is set, can regulates the air-flow size according to the fluid amount and the cleanliness factor of plate face.Of the present utility model simple in structure, easy to use, it is obvious that the fluid of plate face is purged effect, significantly reduced the fluid adhesion amount of plate face, and product is difficult for producing oil mark and oil stain during annealing, guarantee the up-to-standard of production board face.

The specific embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, steam line 1 is connected with U-shaped pipeline 3, the nozzle 2 of flat is connected two ends of U-shaped pipeline 3, and the spout 4 of nozzle 2 is an arcwall face, and the cross section of nozzle 2 is fan-shaped, the longitudinal section of nozzle 2 is trapezoidal, nozzle 2 inside are air storage chamber 6, and spout 4 ends of nozzle 2 adjacent inboards are provided with directed piece 5, and steam line 1 is provided with controlling valve 7, controlling valve 7 can be controlled the flow velocity of air, can regulate the air-flow size according to the fluid amount and the cleanliness factor on plate 9 surfaces; Directed piece 5 is used to change the direction of air-flow, make air-flow when cold roll blows also the both sides to plate 9 purge, guarantee that fluid is blown to the end of cold roll 8, at a high speed under the situation of rotation, fluid is purged the oil return pond at cold roll 8.

During use, the fluid blow device is installed on plate 9 tops after rolling, spout 4 is towards cold roll 8 directions, the jet direction of fluid blow device is opposite with rolling direction, gases at high pressure are delivered to the air storage chamber 6 of nozzle 2 through steam line 1, U-shaped pipeline 3, again by spout 4 ejections, the fluid that the gases at high pressure of ejection carry the surface of plate 9 blows to the end of cold roll 8, under the situation that cold roll 8 rotates at a high speed, fluid is purged the oil return pond, the surface of plate 9 is after this device purges, and the fluid adhesion amount on the plate 9 significantly reduces, and makes end product quality qualified.

The direction of arrow among Fig. 1 is airflow direction.

The direction of arrow among Fig. 3 and Fig. 4 is rolling direction.
