Abstract
The utility model relates to a device for drying a coating of a double-layer coiling welded pipe and belongs to the technical field of coating equipment. The device for drying the coating of the double-layer coiling welded pipe is formed by a bracket, a drying box, a hot blast pipe and a gas ring pump. The upper part of the bracket is provided with the hot blast pipe; the drying box is sleeved at one end of the hot blast pipe; the periphery of the hot blast pipe in the drying box is uniformly provided with gas inlet holes; the lower part of the bracket is provided with the gas ring pump; the gas ring pump is connected with the drying box through an air supply pipe; and the air supply pipe is provided with an air heater. When the device is in use, gas is heated by the air heater and then enters the inside of the hot blast pipe through the gas inlet holes to form circulation thermal gas so as to roast the steel pipe and ensure the coating on the surface of the steel pipe to be rapidly and uniformly dried. The problem that due to inconsistent drying degree of the existing drying device, the coating is adhered in the coiling process of the steel pipe, so that the product quality is influenced is solved. The device has simple structure and reasonable design. A temperature of the gas can be regulated by the air heater. The thermal efficiency is improved. The device is particularly suitable to be used for drying the coating of the double-layer coiling welded pipe.
Description
Technical field
The utility model relates to a kind of twin-laminate roll welding steel pipe coating drying device, belongs to the coating equipment technical field.
Background technology
Double-deck roll-welding steel pipe all will apply layer protective layer after rolling completion, i.e. application is to prolong the service life of steel pipe.For the quality that makes application guarantees to some extent, prevent that also steel pipe coating when furling from sticking together simultaneously, destroy the protective layer that applies, steel pipe must carry out drying to steel pipe after application is accomplished.Existing steel pipe coating drying device is that the steel pipe that moves is passed in the drying baker of drying device and makes the coating of steel tube surface dry when steel pipe is carried out drying, but because the drying baker space of existing drying device is big; Do not have partitioning device between the steel pipe, cause the power consumption of drying unit big, production cost is high, efficient is low; And the degree of drying of steel pipe coating differs; Often cause steel pipe coating when furling to stick together, destroy the protective layer that steel pipe applies, have a strong impact on the quality of product.
Summary of the invention
The purpose of the utility model is: provide a kind of through being arranged on the circulation hot gas that warm-air pipe produced in the drying baker; Make steel pipe when passing warm-air pipe with its coating surfaces flash baking; Big to solve existing drying device power consumption; Production cost is high, and steel pipe coating degree of drying differs, and causes steel pipe coating when furling to stick together and influences the twin-laminate roll welding steel pipe coating drying device of product quality problem.
The utility model is to realize above-mentioned purpose through following technical scheme:
A kind of twin-laminate roll welding steel pipe coating drying device; It is made up of support, drying baker, warm-air pipe, compression ring pump; It is characterized in that: the top of support is provided with warm-air pipe, and an end of warm-air pipe is set with drying baker, is evenly equipped with air admission hole on the warm-air pipe circumference in the drying baker; The bottom of support is equipped with the compression ring pump, and the compression ring pump is connected with drying baker through ajutage, and described ajutage is provided with fan heater.
The utility model beneficial effect compared with prior art is:
The gas heating that this twin-laminate roll welding steel pipe coating drying device produces the compression ring pump through fan heater; And be delivered to drying baker through ajutage; Enter into formation circulation hot gas in the warm-air pipe through air admission hole; Thereby the steel pipe to passing warm-air pipe toasts, and makes its face coat rapid and uniform dry; Institute causes steel pipe coating when furling to stick together because degree of drying differs to have solved existing drying device, influence product quality, and power consumption is big, the problem that production cost is high.This coating drying device is simple in structure, reasonable in design, through fan heater adjustable gas temperature, has improved heat energy efficiency, is specially adapted to the dry use of twin-laminate roll welding steel pipe coating.
Description of drawings:
Accompanying drawing 1 is the structural representation of twin-laminate roll welding steel pipe coating drying device.
Among the figure: 1, support, 2, drying baker, 3, warm-air pipe, 4, the compression ring pump, 5, air admission hole, 6, ajutage, 7, fan heater, 8, double-deck roll-welding steel pipe.
The specific embodiment:
This twin-laminate roll welding steel pipe coating drying device is made up of support 1, drying baker 2, warm-air pipe 3, compression ring pump 4, and the top of support 1 is provided with warm-air pipe 3, and an end of warm-air pipe 3 is set with drying baker 2, is evenly equipped with air admission hole 5 on warm-air pipe 3 circumference in the drying baker 2; The bottom of support 1 is equipped with compression ring pump 4, and compression ring pump 4 is connected with drying baker 2 through ajutage 6, and described ajutage 6 is provided with fan heater 7.
During this twin-laminate roll welding steel pipe coating drying device work; The double-deck roll-welding steel pipe 8 of operation under the effect of draw-gear; Level is passed in the warm-air pipe 3 of this device, and fan heater 7 heats the gas that compression ring pump 4 produces, and is delivered in the drying baker 2 through ajutage 6.The hot gas that enters in the drying baker 2 enters in the warm-air pipe 3 through air admission hole 5, and forms the circulation hot gas, thereby the double-deck roll-welding steel pipe 8 that passes warm-air pipe 3 is toasted, and makes its face coat rapid and uniform dry.
This coating drying device is simple in structure; Reasonable in design, through fan heater 7 adjustable gas temperature, solved the problem that existing drying device power consumption is big, production cost is high; And make the hot gas that enters in the warm-air pipe form circulation through air admission hole; Improved the thermal efficiency, institute causes steel pipe coating when furling to stick together influence the problem of product quality because degree of drying differs to have avoided existing drying device, is specially adapted to the use of twin-laminate roll welding steel pipe coating drying.
