Abstract
The utility model discloses an enforced air exhausting device of an extruding machine, which can prevent solid grains with greater grain diameters from entering a vacuum pump. The enforced air exhausting device comprises the vacuum pump, wherein an air exhausting buffering bucket is arranged above the vacuum pump; one part of the bottom wall or the side wall of the air exhausting buffering bucket, which is close to the bottom wall, is provided with an air inlet; one part of a top cover or the side wall of the air exhausting buffering bucket, which is close to the top, is provided with an air outlet; an air outlet of a machine cylinder of the extruding machine is communicated with an air inlet of the air exhausting buffering bucket through an air exhausting pipe; and an air outlet of the air exhausting buffering bucket is communicated with an air inlet of the vacuum pump through an air pumping pipe. The enforced air exhausting device guarantees that the solid grains with greater grain diameters, which are discharged from the air exhausting opening of the machine cylinder of the extruding machine, are not sucked into the vacuum pump and the normal work of the vacuum pump is guaranteed, so that the whole extruding process can be carried out normally and the service life of the vacuum pump is prolonged.
Description
Technical field
The utility model relates to extruder, refers more particularly to the forced exhaust unit of extruder.
Background technology
Extruder is provided with exhaust apparatus at its machine barrel usually in order to increase work efficiency and to improve melt quality.And exhaust is divided into the nature exhaust and to vacuumize as main forced exhaust, obviously, the effect of forced exhaust will obviously be better than the nature exhaust.
At present, the forced exhaust unit of extruder, its structure comprises: be communicated with by blast pipe between the gas outlet on vavuum pump and the blast pipe, the air inlet of vavuum pump and extruder barrel.This forced exhaust unit in actual use, often mixing the solid particles such as many low molecule precipitates the gas that exhaust outlet from extruder barrel is discharged, the particle diameter of the solid particle that has is also larger, after these solid particles are inhaled in the vavuum pump, not only can have influence on the normal use of vavuum pump, sometimes also can directly damage vavuum pump, greatly shorten the service life of vavuum pump; After vavuum pump damages, as can not in time being found and change, will have influence on because exhaust is not smooth normal production.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of immobilized particles of avoiding greater particle size to enter the forced exhaust unit of the extruder of vavuum pump.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the forced exhaust unit of extruder, comprise: vavuum pump, the top of vavuum pump is provided with the exhaust buffer barrel, on the diapire of exhaust buffer barrel or the close diapire place of sidewall offers air inlet, on the exhaust buffer barrel top cover or place, the close top of sidewall offers the gas outlet, gas outlet on the extruder barrel is communicated with by blast pipe with the air inlet of exhaust buffer barrel, and the gas outlet of exhaust buffer barrel is communicated with by exhaust tube with the air inlet of vavuum pump.
The air inlet of described exhaust buffer barrel is opened on the sidewall of exhaust buffer barrel, and the diapire of described exhaust buffer barrel is flip structure.
The concrete set-up mode of described flip-shell diapire is: a side of diapire links to each other by the sidewall of hinge with a corresponding side, is provided with collision bead formula locking mechanism between the sidewall of the opposite side of diapire and a corresponding side.
The beneficial effects of the utility model are: the utility model is owing to be provided with the buffering exhaust bucket, the air inlet of exhaust buffer barrel is opened on the diapire or the close diapire place of sidewall, the gas outlet of exhaust buffer barrel is opened on the buffer barrel top cover or sidewall is located near the top, gas outlet on the extruder barrel is communicated with by blast pipe with the air inlet of exhaust buffer barrel, the gas outlet of exhaust buffer barrel is communicated with by exhaust tube with the air inlet of vavuum pump, so that the solid particle of the greater particle size that exhaust outlet is discharged from the extruder barrel is deposited on the diapire of exhaust buffer barrel, be not inhaled in the vavuum pump, guaranteed the normal operation of vavuum pump, thereby guaranteed normally carrying out of whole extrusion, prolonged the service life of vavuum pump; In addition, the diapire of flip structure is so that the cleaning collection work of exhaust buffer barrel becomes very easy.

Fig. 1 is a kind of structural representation of the present utility model.
Reference numeral among the figure: 1, machine barrel, 11, steam vent, 2, blast pipe, 3, vavuum pump, 4, the exhaust buffer barrel, 41, sidewall, 42, diapire, 43, top cover, 5, exhaust tube, 6, delivery pipe.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments described in the utility model in detail.
As shown in Figure 1, a kind of forced exhaust unit of extruder, comprise: vavuum pump 3, the top of vavuum pump 3 is provided with exhaust buffer barrel 4, the sidewall 41 of exhaust buffer barrel 4 offers air inlet near diapire 42 places, the sidewall 41 of exhaust buffer barrel 4 offers the gas outlet near the place, top, gas outlet on the machine barrel 1 of extruder (usually being made of several rows of pore 11) is communicated with by blast pipe 2 with the air inlet of exhaust buffer barrel 4, the gas outlet of exhaust buffer barrel 4 is communicated with by exhaust tube 5 with the air inlet of vavuum pump 3, and reclaim by the gas of 6 pairs of discharges of delivery pipe the gas outlet of vavuum pump 3.In the present embodiment, described exhaust buffer barrel 4 also can be dustproof by top cover 43 is set; For easy cleaning is collected, the diapire 42 of exhaust buffer barrel 4 is arranged to flip structure, its concrete set-up mode is: be flexibly connected at a side of the diapire 42 of exhaust buffer barrel 4 sidewall 41 by hinge and exhaust buffer barrel 4 corresponding sides, (hinge and collision bead formula locking mechanism are routine techniques to be provided with collision bead formula locking mechanism between the sidewall 41 of the opposite side of the diapire 42 of exhaust buffer barrel 4 and exhaust buffer barrel 4 corresponding sides, and, be not inventive point, so not shown in FIG.).
Certainly, the air inlet of exhaust buffer barrel 4 also can be arranged on the diapire 41 of exhaust buffer barrel 4, and the gas outlet of described exhaust buffer barrel 4 also can be arranged on the top cover 43 of exhaust buffer barrel 4.
In actual use, when exhaust buffer barrel 4 is full soon, can below exhaust buffer barrel 4, place collection container, then, open the diapire 42 of exhaust buffer barrel 4, so that the material in the exhaust buffer barrel 4 falls into collection container, cleaning and collection are carried out simultaneously, and be very easy to use.
