Further, aforesaid vacuum screw rod transmission pump, wherein, described screw rod comprises single shaft, twin shaft or three-axis structure, the screw rod of described twin shaft or three-axis structure is parallel to each other in vacuum chamber and feed cavity.
Further, aforesaid vacuum screw rod transmission pump, wherein, described screw rod is connected with motor through main driving axle.
Further again; Aforesaid vacuum screw rod transmission pump; Wherein, main driving axle drives and is arranged in the gear case, is provided with in the described gear case respectively to be connected with driven transmission shaft and intermeshing synchronizer gear with main driving axle; The screw rod that main driving axle is corresponding different respectively with driven transmission shaft, the end of initiative drive shaft is connected with motor through the device that is flexible coupling.
Further, aforesaid vacuum screw rod transmission pump, wherein, the described blow off valve that is arranged on the vacuum chamber comprises valve seat and spool, and spool is provided with pull back spring, and the pull back spring upper end is provided with look nut, and valve seat is provided with vacuum tube joint.
The beneficial effect of the utility model is following: the vacuum screw rod transmission pump that the utility model provided utilizes the screw rod mode of motion; Side in feed cavity is provided with vacuum chamber; Help getting rid of the gas in the material, because the spiral thrust effect offsets with pull of vacuum; Material is difficult for getting into vacuum chamber, but has only gas to extract out.The utility model can be carried various meat stuffings, cheese, jam, vegetable juice etc., and it is wide to be suitable for range of viscosities, and discharge capacity is big; No pulse, nothing stir, carry steadily in the work, and noise is low, fault rate is low, efficient is high.
Description of drawings
Fig. 1 is the external structure composition diagram of the vacuum screw rod transmission pump that the utility model provided;
Fig. 2 is the inner structure scheme drawing of vacuum screw rod transmission pump;
Fig. 3 is vacuum chamber, the feed cavity of vacuum screw rod transmission pump, the assembly drowing in discharging chamber.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed explanation.
As shown in Figure 1, the vacuum screw rod transmission pump that the utility model provided comprises the feed cavity 5 and discharging chamber 6 that is interconnected, and the top of feed cavity 5 is provided with inlet point 4; The end in discharging chamber 6 is provided with discharging opening 7; Wherein, be connected with vacuum chamber 3 at the opposite side of feed cavity 5 with respect to discharging chamber 6, vacuum chamber 3 is provided with blow off valve; The opposite side of vacuum chamber 3 is provided with gear case 2, and the screw rod that is driven by motor 1 runs through vacuum chamber 3 and feed cavity 5 successively.
As shown in Figure 2, the vacuum screw rod transmission pump that present embodiment provided comprises that 10, two screw rods of two screw rods are parallel to each other in vacuum chamber 3 and feed cavity 5; Screw rod 10 is provided with conveyor screw; The end of two screw rods 10 connects transmission shaft respectively, and wherein main driving axle 9 is connected through the device that is flexible coupling with motor 1, and transmission shaft is arranged in the gear case 2; Be provided with in the described gear case 2 respectively and be connected with driven transmission shaft 11 and intermeshing synchronizer gear 12 with main driving axle 9; When main driving axle 9 was rotated by driven by motor, driven transmission shaft 11 was driven through the rotation of synchronizer gear 12, thereby two screw rods are rotated synchronously.Junction in feed cavity and discharging chamber is provided with bearing support 8.The utility model is not limited to adopt the twin screw transmission pump of cross-compound arrangement, adopts single screw rod transmission pump of single-shaft configuration or three screw rod transmission pumps of three-axis structure etc. all to be applicable to the mentality of designing of the utility model.
