Abstract

A descaling box for steel pipes relates to the technical field of descaling steel pipes, and adopts the structure that through holes are respectively formed on two side walls in the middle of a box body, a collecting tank is internally arranged at the lower part of the box body, a nozzle rack is arranged at the upper part, nozzles are arranged on the nozzle rack, water inflow ends of all the nozzles are connected to the same liquor feeding pipe fixedly supported on the nozzle rack, the outer end of the liquor feeding pipe is arranged on the side wall of the box body through a sealing piece, and a sand separator is arranged at the inner upper part of the box body and on one side of the nozzle rack. In the utility model, descaling sand is fed into the box body through the sand separator, high-pressure water is fed into the nozzles through the liquor feeding pipe, and the descaling sand and the high-pressure water are mixed in the box body to obtain mixture of high-pressure descaling sand and water. When a seamless steel pipe enters the box body from the through hole on one side of the box body, the mixture of high-pressure descaling sand and water scours both the inner surface and the outer surface of the steel pipe, and the collecting tank collects sand water generated by descaling to facilitate follow-up recycling.

Description

The steel pipe De-scaling box
Technical field
The utility model relates to steel pipe technique of scale removal field.
Background technology
Along with the quickening of China's seamless steel tube production speed and the continuous expansion of construction scale, its production equipment and production technology have all obtained significant progress, also have many deficiencies but compare with some developed countries, some old equipment and traditional processing technology all are faced with challenge.
Seamless steel pipe in heating process, ferro element generation oxidation reaction and diffusion in the oxygen in the furnace gas, carbon dioxide, moisture etc. and the steel top layer, the surface forms a large amount of iron scales.For following road cold-drawn operation, carry out surface scale and remove, be i.e. the steel pipe technique of scale removal.Traditional handicrafts such as pickling, ball blast are generally adopted in present domestic de-scaling, and spent acid and waste gas serious environment pollution that pickling produces more and more are subjected to the restriction of national environmental protection.The dust pollution that ball blast produces is also very serious, and causes the steel tube surface distortion that a lot of pockmarks are arranged, and equipment investment is big, the operating cost height.Metal wire rod or the bars by grinding water jet descaling method and the equipment of the wire rod of the cold stainless steel/carbon of Hangzhou Iron and Steel Group Corp, bar and band steel high pressure water shot blasting descaling method and Hunan Nonferrous Heavy Machinery Co., Ltd, be to adopt the water under high pressure mixed liquor to be ejected into the surface of steel, be mainly used in the outer surface de-scaling of products such as wire rod, bar, and in seamless steel tube production process, because the steel pipe internal-surface oxide skin that heat treatment produces can't be removed, to such an extent as to can't satisfy the requirement of road cold-drawn operation down.
The utility model content
In order to change above defective, now using de-scaling sand water instead directly carries out high pressure to the surface of steel pipe and washes away, to realize the purpose of de-scaling, because used de-scaling sand water is the mixture of de-scaling sand and water, realize the direct injection of high pressure sand water, and reach the purpose of washing away, a kind of steel pipe De-scaling box of essential design, also to collect reusable edible to the sand water that washes away.
The utility model comprises casing, two sidewalls at the casing middle part are provided with through hole respectively, the bottom is provided with feeder in casing, at the casing internal upper part jet nozzle is set, shower nozzle is set on jet nozzle, and the water inlet end of described each shower nozzle is connected on the same feed tube, and described feed tube is fixedly supported on the described jet nozzle, the outer end of described feed tube is arranged on the sidewall of casing by seal, the top in casing, in a side of jet nozzle sand separator is set.
The utility model is sent into de-scaling sand in the casing by sand separator, by feed tube water under high pressure is sent into each shower nozzle, and in casing de-scaling sand is mixed with water under high pressure, forms the mixture of high pressure descaling sand and water.When seamless steel pipe when the through hole of casing one side enters, the mixture of this high pressure descaling sand and water can wash away the inside and outside surface of steel pipe, the sand water of feeder after to de-scaling is collected the back so that enter follow-up recycling.
Adjust the height and position of shower nozzle for convenience, be beneficial to the inside and outside surface of steel pipe is washed away, the utility model is provided with lowering or hoisting gear in the casing upper end, and the lower end of described lowering or hoisting gear vertically is inserted in the casing, the fixedly connected described jet nozzle in the lower end of lowering or hoisting gear.
In order to make above-mentioned lifting more reliable, between the outside of described jet nozzle and the casing guider is set.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, two sidewalls at casing 1 middle part are provided with through hole 2,3 respectively, bottom in the casing 1 is provided with feeder 4, top in the casing 1 is provided with jet nozzle 5, shower nozzle 6 is set on jet nozzle 5, and the water inlet end of each shower nozzle 6 is connected on the same feed tube 7, and feed tube 7 is fixedly supported on the jet nozzle 5, the outer end of feed tube 7 is arranged on the sidewall of casing 1 by seal 8, the top in the casing 1, in a side of jet nozzle 5 sand separator 9 is set.Casing 1 upper end is provided with lowering or hoisting gear 10, and the lower end of lowering or hoisting gear 10 vertically is inserted in the casing 1, and the fixedly connected jet nozzle 5 in the lower end of lowering or hoisting gear 10 is provided with vertical guider 11 between the outside of jet nozzle 5 and the casing 1.
