Abstract
The outer glue of the steelplastic pipe production line of the utility model coats the device vacuumized, it includes: mixed flow tube and silencing means, the arrival end of mixed flow tube is equipped with pneumatics wind intake valve, the outlet end of mixed flow tube is equipped with exhaust pipe, silencing means is set on exhaust pipe, it is provided with negative pressure mouth in the side of mixed flow tube, the diameter of mixed flow tube arrival end is greater than the diameter of mixed flow tube outlet end.The device that the outer glue coating of the steelplastic pipe production line of the utility model vacuumizes is to install negative pressure generator and muffler additional, it exports to generate volume and inhale in mixed flow tube using pneumatics wind and flow, so that the air around mixed flow tube outlet is constantly sucked away, the pressure in adsorbent chamber is set to reach quiet negative pressure state, thus coating and the quiet working environment of the outer glue densification of realization.
Description
Technical field
The utility model relates to vacuum plant, negative pressure is generated especially with pneumatics wind and reaches that outer glue closely coat and nothing is made an uproar
The outer glue of the steelplastic pipe production line that sound generates coats the device vacuumized.
Background technique
In steel-plastic composite pipe production process, it is one of critical process that outer glue, which is coated on steel pipe, and coating procedure is
Continuously, this just determines that outer glue closely coats the importance of required vacuum guarantee.It is real that vacuum pump is often used in production
Existing negative pressure.But the easily cooled scale of vacuum pump and zinc powder blocking and noise is larger, this there is a kind of hidden danger, i.e. vacuum pump quilt
Stifled to can not work normally, outer glue just can not be closely coated on steel pipe, to make production disruption.In order to avoid such as a result, logical
It crosses installation negative pressure generator and muffler and generates negative pressure and noiseless, reach continuous and stable production.
Summary of the invention
The goal of the invention of the utility model is the easily cooled scale of vacuum pump to be solved and zinc powder blocking and noise is biggish
Problem, and a kind of device that the outer glue coating of steelplastic pipe production line vacuumizes is provided, which can work continuously for a long time, and be
The improvement device of noiseless pollution.
In order to complete the goal of the invention of the utility model, the utility model uses following technical scheme:
A kind of outer glue of steelplastic pipe production line of the utility model coats the device vacuumized, it includes: mixed flow tube and noise reduction
Device, in which: the arrival end of mixed flow tube is equipped with pneumatics wind intake valve, and the outlet end of mixed flow tube is equipped with exhaust pipe, on exhaust pipe
It is set with silencing means, is provided with negative pressure mouth in the side of mixed flow tube；
A kind of outer glue of steelplastic pipe production line of the utility model coats the device vacuumized, in which: the mixed flow tube inlet
The diameter at end is greater than the diameter of mixed flow tube outlet end.
The device that a kind of outer glue coating of steelplastic pipe production line of the utility model vacuumizes is to install negative pressure generator additional and disappear
Sound device is exported to generate volume and inhale and be flowed using pneumatics wind in mixed flow tube, so that the air around mixed flow tube outlet is constantly sucked away,
The pressure in adsorbent chamber is set to reach quiet negative pressure state, thus coating and the quiet working environment of the outer glue densification of realization.
Detailed description of the invention
Fig. 1 is that the outer glue of steelplastic pipe production line of the utility model coats the device vacuumized.
In Fig. 1, label 1 is pneumatics wind intake valve；Label 2 is mixed flow tube；Label 3 is negative pressure mouth；Label 4 is exhaust
Pipe；Label 5 is silencing means.
Specific embodiment
As shown in Figure 1, the device that the outer glue coating of the steelplastic pipe production line of the utility model vacuumizes includes: 2 He of mixed flow tube
Silencing means 5, the arrival end of mixed flow tube 2 are equipped with pneumatics wind intake valve 1, and the outlet end of mixed flow tube 2 is equipped with exhaust pipe 4, mixed flow tube 2
The diameter of arrival end is greater than the diameter of 2 outlet end of mixed flow tube.Silencing means 5 is set on exhaust pipe 4, in the side of mixed flow tube 2
Face is provided with negative pressure mouth 3.
Volume is generated in the outlet end of mixed flow tube 2 using pneumatics wind and inhales flowing, so that the air around the outlet end of mixed flow tube 2
It is constantly sucked away, the pressure in adsorbent chamber is made to reach negative pressure state.The utility model solves vacuum in continuous production process
The defect blocked by zinc powder is pumped, the stability of production is increased, avoids and causes completely to shut down because vacuum pump is blocked, produce
The problem of interruption.
Under normal production scenarios, outer glue head is made to reach negative pressure under closed environment, to realize that outer glue is closely coated in
Above steel pipe, Lai Shixian negative pressure achievees the purpose that vacuumize.Pneumatics wind reaches mixed flow tube 2, mixed flow tube 2 from pneumatics wind intake valve 1
In gas noise is eliminated in silencing means 5, while at negative pressure mouth 3 generate negative pressure, be connected on outer glue head.It is thus real
Negative pressure required for outer glue coats is showed.
Embodiment described above is only described preferred embodiments of the present invention, not to this reality
It is defined with novel range, under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art couple
The various changes and improvements that the technical solution of the utility model is made should all fall into the guarantor that the utility model claims book determines
It protects in range.
