DETAILED DESCRIPTION

[0020] In order to make the objects, technical solutions and advantages of the present application clearer, the following further describes the present application with reference to the embodiments and the accompanying drawings.

[0022] In the present application, unless otherwise specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "under" and "under" the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0023] As Figures 1 to 14As shown, the embodiment of the present application provides a kind of solid-liquid mixture conveying device, including rack 100, the rack 100 is equipped with conveying pipeline 103, the inside of conveying pipeline 103 is equipped with fixed shaft 111 and auger blade 110, the fixed shaft 111 is fixedly arranged in conveying pipeline 103 and extends along the length direction of conveying pipeline 103, the auger blade 110 is coaxially rotatably arranged at the outside of fixed shaft 111, and the inner periphery of auger blade 110 is attached with the outer periphery of fixed shaft 111;The one end of conveying pipeline 103 is also equipped with driving mechanism, the driving mechanism can drive auger blade 110 rotate around fixed shaft 111, so that auger blade 110 is conveyed solid-liquid mixture from back to front, while auger blade 110 is scraped off the liquid material adhered on fixed shaft 111.

[0024] Thus when conveying solid-liquid mixture, since fixed shaft 111 is fixed, and liquid material is easily adhered on fixed shaft 111, the continuous rotation of auger blade 110 can scrape off the liquid material adhered on fixed shaft 111, avoid liquid material adhered on fixed shaft 111 and cannot move, so as to improve the conveying efficiency of solid-liquid mixture.

[0025] As shown, Figure 13 The inside of conveying pipeline 103 is also equipped with flexible lining 106 extending along its length direction, flexible lining 106 is located at the outside of auger blade 110, the fixed shaft 111 is equipped with telescopic assembly, and the telescopic assembly is used for tensioning flexible lining 106, so that part of flexible lining 106 can be tightly attached with the outer periphery of auger blade 110.

[0026] Flexible lining 106 is arranged between auger blade 110 and conveying pipeline 103, flexible lining 106 is wear-resistant and smooth in surface, can avoid the direct contact between auger blade 110 and conveying pipeline 103 to cause the wear of the outer periphery of auger blade 110, and further prevent the backflow of liquid material due to the gap between auger blade 110 and conveying pipeline 103, while telescopic assembly makes flexible lining 106 tightly attached with the outer surface of auger blade 110, can avoid the gap between flexible lining 106 and auger blade 110 to cause the backflow of liquid material, ensure the normal conveying of solid-liquid mixture, and prolong the service life of auger blade 110.

[0027] As shown, Figures 2 to 9As shown, the telescopic assembly includes multiple telescopic rods 112, which extend radially along a fixed shaft 111 and are correspondingly distributed along the length direction of the fixed shaft 111. A telescopic slot 113 is provided on the fixed shaft 111 at a position corresponding to each telescopic rod 112. The telescopic rod 112 slides in the telescopic slot 113, and a compression spring 114 is provided between the telescopic rod 112 and the telescopic slot 113. The compression spring 114 has a tendency to extend the telescopic rod 112 from the telescopic slot 113, thereby causing the telescopic rod 112 to tension the flexible liner 106. This arrangement is simple in structure and facilitates the tensioning of the flexible liner 106.

[0028] Furthermore, the inner wall of the delivery pipe 103 is provided with an insertion groove 1031, and the insertion groove 1031 corresponds to the plurality of telescopic rods 112. The ends of the telescopic rods 112 can push the flexible liner 106 into the insertion groove 1031. This can stretch the flexible liner 106, thereby achieving a better tensioning effect on the flexible liner 106.

[0029] Furthermore, the telescopic rods 112 extend horizontally, and multiple telescopic rods 112 are evenly distributed along the length of the fixed shaft 111. Since large solid materials in the solid-liquid mixture will flip upward around the circumference of the fixed shaft 111 as the auger blades 110 rotate, this flipping will cause the large solid materials to idle at that position instead of moving forward. The horizontally arranged telescopic rods 112 can prevent the large solid materials from flipping upward around the circumference of the fixed shaft 111, thereby promoting the large solid materials to be transported forward along the spiral of the auger blades 110, thereby improving the transportation efficiency of the solid-liquid mixture.

[0030] like Figure 13 and Figure 14 As shown, in the radial direction of the auger blade 110, the thickness of the auger blade 110 gradually decreases from the outside to the inside. In this way, the thickness of the auger blade 110 near its inner peripheral surface is thinner, making it easier to scrape off the liquid material on the fixed shaft 111.

[0031] Furthermore, the end of the telescopic rod 112 is hemispherical, and the auger blade 110 has a helical surface, which is an arcuate concave surface 1101. The end of the telescopic rod 112 can slide with the arcuate concave surface 1101. In this way, when the auger blade 110 rotates about the fixed axis 111, the end of the telescopic rod 112 slides with the arcuate concave surface 1101, which can cause the telescopic rod 112 to gradually retract into the telescopic slot 113.

[0032] like Figure 13 and Figure 14As shown, when the auger blade 110 is away from the telescopic rod 112, the end of the telescopic rod 112 is located in the insertion groove 1031, and when the auger blade 110 gradually approaches the telescopic rod 112, the arc-shaped concave surface 1101 is in sliding fit with the end of the telescopic rod 112, so as to drive the telescopic rod 112 to shrink into the telescopic groove 113.

[0033] Further, the cover plate 102 is detachably installed above the conveying pipeline 103, the middle part of the flexible lining plate 106 is arranged outside the auger blade 110, and the upper end of the flexible lining plate 106 is fixedly arranged on the cover plate 102. Specifically, the upper end of the flexible lining plate 106 is pressed on the cover plate 102 by the pressing plate 115, and the bolts are sequentially threaded through the pressing plate 115, the flexible lining plate 106 and the cover plate 102 to be fixedly connected.

[0034] Further, the rack 100 is further included, the conveying pipeline 103 is arranged on the rack 100 in the up-down direction, the cover plate 102 is provided with the feeding port 104, the feeding port 104 corresponds to the lower end of the conveying pipeline 103, the bottom of the conveying pipeline 103 is provided with the discharging port 105, and the discharging port 105 corresponds to the higher end of the conveying pipeline 103.

[0035] Further, the flexible lining plate 106 is a knife blade. The knife blade is a PVC film formed on the upper and lower surfaces as a base material, a light guide fiber is added between the double-sided PVC interlayer, and the three-layer material is compounded by rotating a hot roller to apply a certain pressure and is cooled and formed. The knife blade has the characteristics of waterproof and wear-resistant.

[0036] The driving mechanism is a driving motor 101, the end of the auger blade 110 is provided with a driving ring, the driving ring is provided with a transmission shaft, and the output end of the driving motor 101 is in transmission fit with the transmission shaft.

[0037] In combination with the above embodiment, the use principle and working process of the embodiment of the application are as follows: In the initial state, the auger blade 110 makes a part of the telescopic rod 112 on the fixed shaft 111 shrink into the telescopic groove 113, another part of the telescopic rod 112 is extended from the telescopic groove 113 of the fixed shaft 111 and enters the insertion groove 1031, so that the flexible lining plate 106 is tensioned and tightly adheres to the outer periphery of the auger blade 110.

[0038] The solid-liquid mixture is put into the feeding port 104, and then the driving motor 101 is started to drive the auger blade 110 to rotate around the fixed shaft 111. When the auger blade 110 rotates, the arc-shaped concave surface 1101 makes the plurality of telescopic rods 112 reciprocate constantly. A fixed number of telescopic rods 112 among the plurality of telescopic rods 112 are always in tension with the flexible lining plate 106, so as to ensure that no gap is generated between the flexible lining plate 106 and the auger blade 110. Since the fixed number of telescopic rods 112 are always in tension with the flexible lining plate 106, and the positions of the telescopic rods 112 in the extended state change constantly, the position of the flexible lining plate 106 corresponding to the insertion groove 1031 forms a wave-shaped groove that changes constantly. The wave-shaped groove can hinder the backward flow of the liquid material in the solid-liquid mixture. With the rotation of the auger blade 110, the spiral surface of the auger blade 110 can drive the solid-liquid mixture to be conveyed forward. Finally, the solid-liquid mixture is discharged from the discharge port 105 at the bottom of the conveying pipeline 103.

[0039] The technical features of the above embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0040] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that, for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
