Description

A continuous production equipment for simultaneous plastic coating of inner and outer walls of multiple tubes

the

technical field

The invention relates to plastic coating equipment, in particular to plastic coating equipment for pipelines.

Background technique

Nowadays, all kinds of steel pipes, such as water pipes, fire pipes, cable casings, etc., are generally fed manually and sent to the chain conveyor to enter the preheating oven for heating. After heating, a steel pipe is sent by the conveying mechanism To the center of the inner spraying, the roller rotates and sprays the inner. After the internal spraying is completed, the steel pipe is transferred to the external wall spraying production line for external wall spraying. After spraying, the steel pipe is sent to the curing furnace by the chain conveyor to be heated and solidified, and the cured steel pipe is cooled to be lowered. However, this technology has low production efficiency, unstable product quality, high energy consumption, high labor intensity and low degree of automation.

Contents of the invention

The purpose of the present invention is to provide a continuous production equipment for the simultaneous plastic coating of the inner and outer walls of multi-tubes, which can solve the coating conditions of steel pipes with different technical anti-corrosion requirements, achieve continuous and uninterrupted production of multi-tubes, and organically connect the production lines together. It can be completed at one time to the next part; the production efficiency is high and the coating performance is stable.

To achieve this purpose, the present invention adopts the following technical solutions:

A continuous production equipment for simultaneous plastic coating of inner and outer walls of multiple tubes, including upper equipment, preheating equipment, plastic coating equipment, curing equipment, cooling equipment and lower equipment, the upper equipment includes an inclined raceway, one end of the raceway A chain conveyor is installed, and the chain conveyor is connected to the preheating drying tunnel. The steel pipe jacking and positioning device is installed on the preheating drying tunnel, and the upper end of the steel pipe jacking and positioning device is equipped with an automatic manipulator. The fluidized bed is soaked, and a plurality of electrostatic powder spray guns are installed in the outer spray room, and the curing equipment includes a conveyor and a curing furnace.

The production equipment of the present invention has multi-pipe continuous production efficiency, can solve the coating conditions required by different technical anticorrosion steel pipes, and achieve multi-pipe continuous and uninterrupted production. Various mechanical devices and manipulators organically connect the production line together, and the steel pipe is completed from the upper piece to the lower piece at one time. High production efficiency and stable coating performance. According to the anti-corrosion requirements of the steel pipe, the process of internal spraying and external spraying or internal spraying and external immersion process is adopted. These two processes can be switched to each other on the same production line.

Compared with similar products, this complete set of equipment has the advantages of low energy consumption, high production efficiency, stable product quality, high degree of automation, no pollution, low noise, and wide application range.

Detailed ways

As shown in Fig. 1, a kind of multi-pipe inner and outer walls are simultaneously coated with plastic continuous production equipment, including upper equipment, preheating equipment, plastic coating equipment, curing equipment, cooling equipment and lower equipment, and the upper equipment includes inclined Raceway 1, chain conveyor 2 is installed at one end of raceway 1, chain conveyor 2 is connected to preheating drying tunnel 3, steel pipe lifting and positioning device 4 is installed on preheating drying tunnel 3, and the upper end of steel pipe lifting and positioning device 4 is set There is an automatic manipulator 5, the plastic coating equipment includes an outer spray room 6 and an outer immersion fluidized bed 7, a plurality of electrostatic powder spray guns are arranged in the outer spray room, and the curing equipment includes a conveyor 8 and a curing furnace 9, the curing furnace 9. Cooling equipment 10 and lower piece equipment 11 are arranged at the back. The lower piece equipment 11 also adopts conveyors and inclined raceways, and finally the coated steel pipes are collected in the steel pipe collection tank.

During production, the steel pipe automatically rolls to the chain conveyor 2 on the unpowered inclined raceway 1, and is conveyed by the chain conveyor 2 into the preheating oven 3, and the steel pipe is heated to the required temperature, and the chain conveyor The conveyor 2 sends the steel pipe out of the preheating oven 3, and then uses the steel pipe jacking and positioning device 4 to lift the steel pipe up and position it, and then uses the hanging mechanism of the automatic manipulator 5 to grab the steel pipe and send it to the plastic coating area. Anti-corrosion requirements, if the internal spraying and external spraying process is adopted, the automatic manipulator 5 will send the steel pipe to the external spraying room 6, and in the external spraying room 6, multiple electrostatic powder spray guns are used to reciprocate the powder coating on the steel pipe, and at the same time, the internal spraying The two ends are self-propelled in the longitudinal direction, and after automatic positioning, the return spray gun is sprayed; if the internal spraying and external immersion process is adopted, the automatic manipulator 5 will quickly rise the steel pipe to the position and move it to the external immersion fluidized bed 7, connect the fan, and use the air volume and air flow of the fan. Press to make the powder in the fluidized bed "boiling". After the boiling liquid-like powder quickly adsorbs on the surface of the outer wall of the steel pipe to form a coating, the automatic manipulator quickly lifts the steel pipe into place, and at the same time, the two ends of the inner spraying machine move longitudinally to start the inner spraying. After the spraying is finished, the automatic manipulator will move the steel pipe to the mouth of the curing furnace and place it on the non-resting device (the automatic manipulator will automatically return to the spraying position), and the conveyor 8 will send the steel pipe to the curing furnace 9 for heating and curing, and the cured steel pipe After being cooled by the cooling device 10, the parts are lowered by the lowering device 11, so as to complete the whole process.
