Abstract

The utility model relates to an adjustable ejector, in particular to an ejector for pneumatic transport of synthetic staple fiber. The ejector body in skew T shape comprises a cotton inlet, an air inlet and a discharge port. A long hole is arranged on a panel of the air inlet, in which a plugboard is hermetically inserted. A throat is arranged between the front end of the plugboard and a lower panel of the air inlet. The position of the plugboard is adjusted to change the size and the ejection angle of the throat. The utility model has the advantages of simple structure, convenient maintenance, low cost and adjustable throat.

Description

A kind of adjustable spraying apparatus

Technical field

The utility model relates to a kind of adjustable spraying apparatus, the injector of carrying especially for the strength of staple fibre.

Background technology

The injector that present chemical fiber factory uses in the staple fibre air-transport system, the aditus laryngis size of its injection is uncontrollable.In patent ZL200720103032.X, disclose a kind of like this technology, because injector is made in advance, all more or less difference is arranged and field erected Pneumatic conveying pipeline system is general with design drawing, especially working state of system is mutually far short of what is expected with the design-calculated data, and when changing aspect product variety, output and/or other, original injector can not adapt to new duty, though or can work, but efficient is low, and system is easily stopped up.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of adjustable spraying apparatus.The size and the jet angle of its aditus laryngis are adjustable.

The technical scheme in the invention for solving the technical problem is: cotton inlet, air inlet and discharging opening are formed the injector body of a skew T form, on the top panel of air inlet, strip hole is arranged, sealing is inserted with plate in the strip hole, form aditus laryngis between the front end of plate and the lower panel of air inlet, the position of adjusting plate can change the size of aditus laryngis.Adjust the position of regulating rod in slotted hole simultaneously, then can regulate the size of aditus laryngis and/or the jet angle of injector simultaneously.

The utility model is simple in structure, and is easy to maintenance, and cost is low, and the size and the jet angle of aditus laryngis are adjustable.After the air-transport system installation, can regulate the size and/or the jet angle of aditus laryngis according to the virtual condition of system, make injector be operated in optimum state, reach purpose energy-conservation, efficient, environmental protection.

Description of drawings

Below in conjunction with embodiment with reference to accompanying drawing the utility model is elaborated.

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A cutaway view among the utility model Fig. 1;

Fig. 3 is the utility model regulating rod 6 schematic diagrames.

The specific embodiment

As shown in Figure 1, cotton inlet 1, air inlet 2 and discharging opening 4 are formed the injector body of a skew T form.Plate 3 passes the strip hole 221 on the top panel 22 of air inlet 2, the long slot bore 61 on the regulating rod 6 successively, extends to cotton inlet 1 below.Like this, plate 3 forms jet 5 with lower panel 21, the

side panel

23,24 of air inlet 2.

As shown in Figure 3, there is a long slot bore 61 centre of regulating rod 6, and plate 3 passes long slot bore 61 and can move flexibly therein.The two ends of regulating rod 6 are screw threads 62.

As shown in Figure 1, 2, on the side panel 23 of air inlet 2, open the slotted hole 231 of an arc, open the slotted hole 241 of a same size arc in the position of the correspondence of side panel 24.Regulating rod 6 passes slotted

hole

231 and 241 and stretches out side panel 23,24.Screw thread place stretching loads onto circular cover 7 respectively, and fastening with nut 8, and cover plate 7 covers slotted

hole

231 and 241, in order to avoid leak out.

Cotton inlet 1 extends in the air inlet 2 near the wall 11 of plate 3, and its forward position surpasses 231,241 1 less distances of slotted hole.

Regulate plate 3 its length L direction along plate in strip hole 221 and long slot bore 61 is moved, can regulate the size of aditus laryngis 5.After adjusting finished, nut 8 needed lemon tight, and the slit between the top panel perforate 221 of plate 3 and air inlet 2 need be used such as material seal (not shown)s such as fluid sealants.Adjust the position of regulating rod (6) in slotted hole (231) and (241) simultaneously, then can regulate the size of aditus laryngis and/or the jet angle of injector simultaneously.
