Abstract
The invention discloses a forced exhausting device of an extruder. The forced exhausting device can prevent solid particles with a great particle size from entering into a vacuum pump and comprises the vacuum pump. An exhausting buffering barrel is arranged above the vacuum pump; an air inlet is provided on a bottom wall of the exhausting buffering barrel or at a position on a side wall of the exhausting buffering barrel close to the bottom wall, and an air outlet is provided on a top cover of the exhausting buffering barrel or at a position on a side wall of the exhausting buffering barrel close to the top; an air outlet on a cylinder of the extruder is communicated with the air inlet of the exhausting buffering barrel through an exhaust pipe, and the air outlet of the exhausting buffering barrel is communicated with an air inlet of the vacuum pump through an extraction pipe. The forced exhausting device provided in the invention guarantees that solid particles with a great particle size discharged from the air outlet on the cylinder of the extruder are not pumped into the vacuum pump, which enables normal operation of the vacuum pump to be ensured, thereby guaranteeing normal implementation of the whole extrusion process and prolonging the service life of the vacuum pump.
Description
Technical field
The present invention relates to extruder, refer more particularly to the forced exhaust device of extruder.
Background technology
Extruder is in order to increase work efficiency and to improve melt quality, and its machine barrel is provided with exhaust apparatus usually.And exhaust is divided into the nature exhaust and be master's forced exhaust to vacuumize, and obviously, the effect of forced exhaust will obviously be superior to the nature exhaust.
At present, the forced exhaust device of extruder, its structure comprises: be communicated with through 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 device in actual use; Often mixing 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 bigger, 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, shorten the service life of vavuum pump greatly; After vavuum pump damages, as can not being had influence on ordinary production because exhaust is not smooth by timely discovery and replacing.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of immobilized particles of avoiding greater particle size to get into the forced exhaust device of the extruder of vavuum pump.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: the forced exhaust device 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 sidewall offer air inlet near the diapire place, on the exhaust buffer barrel top cover or sidewall offer the gas outlet near top place; Gas outlet on the extruder barrel is communicated with through blast pipe with the air inlet of exhaust buffer barrel, and the gas outlet of exhaust buffer barrel is communicated with through exhaust tube with the air inlet of vavuum pump.
The air inlet of said exhaust buffer barrel is opened on the sidewall of exhaust buffer barrel, and the diapire of said exhaust buffer barrel is the flip-shell structure.
The concrete set-up mode of said flip-shell diapire is: a side of diapire links to each other with the sidewall of a corresponding side through hinge, is provided with between the sidewall of the opposite side of diapire and a corresponding side and bumps pearl formula locking mechanism.
The invention has the beneficial effects as follows: the present invention is owing to be provided with buffering exhaust bucket; The air inlet of exhaust buffer barrel be opened on the diapire or sidewall near the diapire place; 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 through blast pipe with the air inlet of exhaust buffer barrel, and the gas outlet of exhaust buffer barrel is communicated with through exhaust tube with the air inlet of vavuum pump, makes the solid particle of the greater particle size that exhaust outlet is discharged from the extruder barrel be deposited on the diapire of exhaust buffer barrel; Be not inhaled in the vavuum pump; Guarantee the operate as normal of vavuum pump, thereby guaranteed normally carrying out of whole extrusion, prolonged the service life of vavuum pump; In addition, the diapire of flip-shell structure makes the cleaning collection work of exhaust buffer barrel become very easy.

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 of the present invention in detail.
As shown in Figure 1; A kind of forced exhaust device of extruder; Comprise: vavuum pump 3, the top of vavuum pump 3 is provided with exhaust buffer barrel 4, and 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 (being made up of several rows of pore 11 usually) is communicated with through blast pipe 2 with the air inlet of exhaust buffer barrel 4, and the gas outlet of exhaust buffer barrel 4 is communicated with through exhaust tube 5 with the air inlet of vavuum pump 3, and reclaim through 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 through top cover 43 is set; Cleaning is for ease collected; The diapire 42 of exhaust buffer barrel 4 is arranged to the flip-shell structure; Its concrete set-up mode is: the side at the diapire 42 of exhaust buffer barrel 4 flexibly connects through the sidewall 41 of hinge with exhaust buffer barrel 4 corresponding sides, be provided with between the sidewall 41 of the opposite side of the diapire 42 of exhaust buffer barrel 4 and exhaust buffer barrel 4 corresponding sides bump pearl formula locking mechanism (hinge and bump pearl formula locking mechanism and be routine techniques, and; Be not inventive point, Gu Tuzhong does not draw).
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 said 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, make 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.
