It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1, as Figure 1-4As shown, the utility model provides a static mixing device, including a mixing drum 1, wherein a feed port 2 and a discharge port 3 are respectively provided at both ends of the mixing drum 1, a feed pipe 13 is fixed on the outer wall of the mixing drum 1, and a mixing unit structure 5 for fully blending the raw materials and the product is provided in the mixing drum 1, and the mixing unit structure 5 includes a first spiral plate 501 fixed in the mixing drum 1, a first spiral groove 503 is provided in the first spiral plate 501, a second spiral plate 502 is fixed in the first spiral plate 501, a second spiral groove 504 is provided in the second spiral plate 502, a plurality of through holes 7 are provided on the plate wall of the first spiral plate 501, connecting cavities 8 are provided at both ends of the plate wall of the second spiral plate 502, a blocking plate 9 is fixed in the connecting cavity 8, and a diversion groove 10 is provided at both ends of the blocking plate 9, and the feed pipe 13 is provided on the outside of the first spiral plate 501 in one of the first spiral grooves 503.

[0019] The effect achieved by the entire embodiment 1 is that, through the setting of the feed port 2 and the discharge port 3, the access port of the device to the outside world can be clearly indicated, and through the setting of the mixing unit structure 5, the raw materials and products entering the device can be guided by the mixing unit structure 5 to be more thoroughly integrated, which is highly practical and prevents the problem of uneven mixing when the mixed materials are discharged.

[0020] Example 2, as Figure 1-4 As shown, the spiral plates of the first spiral plate 501 and the second spiral plate 502 are respectively arranged in the spiral grooves of each other, a central column 6 is provided in the mixing barrel 1, and the first spiral plate 501 and the second spiral plate 502 are fixed to each other through the central column 6, and a baffle 11 is fixed in the mixing barrel 1 at the discharge port 3, and the end of the baffle 11 facing the mixing unit structure 5 is a curved surface, and mounting sleeves 4 are fixed on the outer walls of both ends of the mixing barrel 1, and a plurality of screw holes 12 are provided in the mounting sleeve 4, and a feed pipe 13 is installed at the end close to the feed port 2.

[0021] The effect achieved by the entire embodiment 2 is that the spiral plates of the first spiral plate 501 and the second spiral plate 502 are respectively arranged in the spiral grooves of each other, so that the mixing unit structure 5 is divided into four spiral entry channels, so that the raw materials and products can be divided into four parts for full fusion. Through the setting of the through hole 7, when the raw materials and products enter the first spiral groove 503 and the second spiral groove 504, a part of the product will flow into the other first spiral grooves 503 and the second spiral grooves 504 through the through hole 7, so that a certain turbulence is formed inside the first spiral grooves 503 and the second spiral grooves 504, and the mixing effect will be better.

When the external device starts feeding, the raw materials and products will be mixed through the guidance of the first spiral groove 503 and the second spiral groove 504 opened in the first spiral plate 501 and the second spiral plate 502, and finally discharged from the discharge port 3 to the storage tank for storage. When the raw materials and products enter the first spiral groove 503 and the second spiral groove 504, a part of the products will flow into the other first spiral grooves 503 and the second spiral grooves 504 through the through hole 7 The baffle 9 and the diverter groove 10 are provided to guide the raw materials and products rotating in the first spiral groove 503 and the second spiral groove 504 in layers again, so that the turbulence in the device is increased and the mixing effect is improved. The baffle 11 has a curved surface at one end facing the mixing unit structure 5. When the mixed material of the device is ready to be discharged from the discharge port 3, a part of the mixed material will hit the baffle 11, and then flow back through the gap between the baffle 11 and the mixing barrel 1 under the guidance of the curved surface of the baffle 11, and then flow out from the gap between the baffle 11 and the mixing barrel 1, once again achieving the effect of reflux collision mixing, thereby improving the mixing effect.
