Summary of the invention
The objective of the invention is: a kind of convenience for washing, batch mixing polyurethane mixing device more uniformly is provided.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: the polyurethane mixing device, and its structure comprises: Connection Block; Motor is installed on the Connection Block, and the lower end of Connection Block is provided with valve seat, and the lower end of said valve seat is provided with mixing machine; The lower end of mixing machine is provided with discharging opening, is provided with connecting axle in the described Connection Block, and the upper end of described connecting axle is connected with motor output shaft; The lower end of described connecting axle pass behind the valve seat with mixing drum in the top of batch mixing rod be connected; Described valve seat is provided with charging aperture, and the intracavity inter-connection of charging aperture and mixing machine also is provided with water inlet on the described valve seat; Described water inlet also with the intracavity inter-connection of mixing machine, vertically be provided with the batch mixing pin on the outer wall of described batch mixing rod along the bifilar helix track.
Further; Aforesaid polyurethane mixing device; Wherein, be provided with throttle seat between described mixing machine and the discharging opening, thin and middle in the middle of the inner chamber of described throttle seat is to the two ends shape of chap gradually; The bottom of described batch mixing rod is provided with the taper strangling head that the inner chamber with throttle seat cooperatively interacts, and described taper strangling head is connected with the excellent threaded engagement of batch mixing.
Advantage of the present invention is: use the batch mixing pin that is provided with along bifilar helix to substitute the batch mixing impeller on traditional batch mixing rod, on the one hand, reduced the contact area with raw material, raw material is residual few, convenience for washing; On the other hand, make the raw material in the mixing machine be in abundant stir mixing state all the time, batch mixing is more even; Adopt the structure of batch mixing pin to alleviate the weight of whole device in addition, make the polyurethane mixing device lighter.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the present invention is done further detailed description.
Like Fig. 1, Fig. 2, shown in Figure 3, the polyurethane mixing device, its structure comprises: Connection Block 1; Motor 2 is installed on the Connection Block 1, and the lower end of Connection Block 1 is provided with valve seat 3, and the lower end of said valve seat 3 is provided with mixing machine 4; The lower end of mixing machine 4 is provided with discharging opening 5, is provided with connecting axle 6 in the described Connection Block 1, and the upper end of described connecting axle 6 is connected with motor 2 output shafts; The top that the batch mixing excellent 7 in valve seat 3 back and the mixing machine 4 is passed in the lower end of described connecting axle 6 is connected; Described valve seat 3 is provided with charging aperture 31, and the intracavity inter-connection of charging aperture 31 and mixing machine 4 also is provided with water inlet 32 on the described valve seat 3; Described water inlet 32 also with the intracavity inter-connection of mixing machine 4, vertically be provided with batch mixing pin 71 on the outer wall of described batch mixing rod 7 along the bifilar helix track.Be provided with throttle seat 8 between described mixing machine 4 and the discharging opening 5; It is thin and middle in the middle of the inner chamber of described throttle seat 8 is to the two ends shape of chap gradually; The bottom of described batch mixing rod 7 is provided with the taper strangling head 9 that the inner chamber with throttle seat 8 cooperatively interacts, and described taper strangling head 9 is connected with excellent 7 threaded engagement of batch mixing.
Operation principle of the present invention is following: raw material is added in the mixing machine 4 from charging aperture 31; Motor 2 drives connecting axle 6 and drives 7 rotations of batch mixing rod; The rotation direction of batch mixing rod 7 should make the batch mixing pin 71 that is provided with along spiral trajectory when stirring raw material, has the trend that raw material is moved upward.All raw materials in the mixing machine 4 are along with the rotation of batch mixing rod 7 is stirred by batch mixing pin 71; Under the gravity effect; Raw material drops downwards when stirring, and the trend that raw material is had when batch mixing rod 7 rotates simultaneously to move upward has so just been slowed down the speed that raw material drops downwards; Prolonged the time of in mixing machine 4, mixing, therefore mixed more evenly.Owing between discharging opening 5 and mixing machine 4, be provided with throttle seat 8; The taper strangling head 9 that has been threaded in the bottom of batch mixing rod 7, the position of adjustment taper strangling head 9 changes the pore size between the internal chamber wall of tapering part and throttle seat 8 of taper strangling head 9; Just can regulate the speed of discharging in the discharging opening 31; When raw material is slow than the thickness falling speed, can adjust upward taper strangling head 9, the space between the internal chamber wall of increase taper strangling head 9 and throttle seat 8 makes raw material be convenient to discharging; When raw material is thinner, when falling speed is very fast, can adjust taper strangling head 9 downwards, reduce the space between the internal chamber wall of taper strangling head 9 and throttle seat 8, the discharging speed of raw material is reduced.Batch mixing finishes the back when cleaning, and only needs from water inlet 32, to feed cleaning agent and enters into mixing machine 4 and get final product, owing to be provided with batch mixing pin 71, the residual raw material after the batch mixing completion on batch mixing pin 71 significantly reduces, and cleans very convenient.
Advantage of the present invention is: the batch mixing impeller of using the batch mixing pin 71 that is provided with along bifilar helix to substitute on traditional batch mixing rod, on the one hand, reduced the contact area with raw material, and raw material is residual few, convenience for washing; On the other hand, make the raw material in the mixing machine 4 be in abundant stir mixing state all the time, batch mixing is more even; Adopt the structure of batch mixing pin 71 to alleviate the weight of whole device in addition, make the polyurethane mixing device lighter.
