Abstract
The utility model relates to an exhaust pipeline system of a pre-foaming machine. The exhaust pipeline system comprises an upper exhaust pipe and a lower exhaust pipe group, wherein a transverse connection pipe is arranged between the upper exhaust pipe and the lower exhaust pipe group; the lower exhaust pipe group comprises a lower exhaust main pipe and a plurality of lower exhaust branch pipes; exhaust valves are respectively arranged on the lower exhaust main pipe and the lower exhaust branch pipes. The exhaust pipeline system of the pre-foaming machine is simple in structure, convenient to operate, stable in performance and reliable to use, and air flow can be accurately regulated, so that the product quality can be improved.
Description
Technical field
The utility model relates to a kind of prefoaming machine gas discharge pipe system.
Background technology
In the staving of common plastics foam pre-expander, exhaust apparatus is installed all at present, usually between the upper blast pipe of this class exhaust apparatus and lower blast pipe, be fixed with large air bleeding valve, the two ends of two little blast pipes are connected with upper blast pipe and lower blast pipe respectively, two gas releasing valve for secondaries are separately fixed on a little blast pipe, and this class exhaust apparatus is by a large air bleeding valve and two gas releasing valve for secondaries and the pressure in plastic foam prefoaming machine staving is regulated.
Wherein people's air bleeding valve mainly plays the effect of protection staving, prevents the hypertonia in staving, guarantees to produce and can carry out smoothly, and large air bleeding valve is sometimes also for the pressure in the fast evacuation staving.Two gas releasing valve for secondaries are used in combination, and be used to regulating the pressure size in staving, guarantee that the pressure in staving keeps constant.
Because large air bleeding valve is mainly the effect of playing the protection staving; that is to say that large air bleeding valve is to regulating the almost not effect of pressure size in staving; and the pressure size in staving is only regulated by two gas releasing valve for secondaries; make the adjustable scope of staving internal pressure of a plastic foam prefoaming machine less; thereby reduced the applicable surface of plastic foam prefoaming machine, and this class exhaust apparatus is difficult to guarantee the staving internal pressure stabilises.
The specification of the plastic foam prefoaming machine formed due to the different manufacturers manufacture is again had any different, and the manufacturer of plastic foam required staving internal pressure when using the plastic foam of plastic foam prefoaming machine production different model is also had any different, this just makes the applicable surface of the plastic foam prefoaming machine that uses existing exhaust apparatus less, different plastic foam manufacturers and different plastic foam manufacturing process need the exhaust apparatus of different capacities, this has just improved production cost greatly, has reduced the utilization rate of equipment.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, easy to use, can guarantee the prefoaming machine gas discharge pipe system that the staving internal pressure is constant.
In order to realize the foregoing invention purpose, the technical solution of the utility model is: a kind of prefoaming machine gas discharge pipe system, comprise blast pipe and lower exhaust stack, between described upper blast pipe and lower exhaust stack, be provided with the connection transverse tube, described lower exhaust stack comprises lower exhaust supervisor and some lower exhaust branch pipes, is equipped with air bleeding valve on lower exhaust supervisor and lower exhaust branch pipe.
Preferably, described lower exhaust branch pipe is arranged on the lower exhaust supervisor left and right sides, and each side is provided with two, and is equidistant distribution.
Preferably, described upper blast pipe is provided with hand-operated valve.
Preferably, described lower exhaust supervisor caliber is greater than lower exhaust branch pipe.
The utility model is simple in structure, easy to operate, and stable performance is used reliably, regulates air-flow more accurate, thereby more is conducive to improve the quality of product.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with concrete the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1: a kind of prefoaming machine gas discharge pipe system, comprise blast pipe 1 and lower exhaust stack, between described upper blast pipe 1 and lower exhaust stack, be provided with and connect transverse tube 2, described lower exhaust stack comprises lower exhaust supervisor 3 and some lower exhaust branch pipes 4, on lower exhaust supervisor and lower exhaust branch pipe, be equipped with air bleeding valve, wherein descend the exhaust supervisor to be provided with main exhaust valve 5, lower exhaust branch pipe is provided with angle pedestal valve 6.Described lower exhaust branch pipe 4 is arranged on lower exhaust supervisor 3 left and right sides, and each side is provided with two, and is equidistant distribution, and described upper blast pipe is provided with hand-operated valve 7, and described lower exhaust supervisor caliber is greater than lower exhaust branch pipe.
Adopt many Design of Exhaust Manifolds, make the gas extraction system performance more stable, exhaust airstream is regulated more accurate, thereby is conducive to improve the quality of products, and it is convenient that the setting of hand-operated valve also makes whole gas extraction system safeguard.
