Detailed Description

This is described in detail below with reference to fig. 1-4.

Example 1

The present embodiments provide an extrusion mechanism for viscous mineral. As shown in fig. 1, the extrusion mechanism includes an extrusion roller body 100. The pressing roller body 100 includes a key groove at a central position thereof for fixing the driving shaft so that the pressing roller body 100 can rotate. As shown in fig. 1, an extrusion gap 400 is provided between the first surface body 200 and one radial side of the extrusion roller body 100. The width of the narrowest part of the extrusion gap 400 is between 5 and 20 mm. The width of the narrowest point of the extrusion gap 400 is the distance of the roll surface from the first surface body. Preferably, the first surface body 200 may be a plane body or a curved body. The viscous material is extruded through the extrusion gap by the rotation of the extrusion roller body 100. But due to the viscosity of the viscous material, the viscous material is easy to adhere to objects on two sides of the gap, so that the extrusion gap is blocked. Therefore, as shown in fig. 2, the first protrusions 500 are arranged on the roll surface of the extrusion roll body in the circumferential direction thereof. This first convex body 500 forms an annular convex belt to imitate the effect of desorption soil of dung beetle or the self-cleaning effect on lotus surface, thereby make the viscidity material can be automatically from the desorption on roll surface 200. Preferably, the first convex body 500 is a body of revolution formed by a smooth curve revolution, such as a spherical or ellipsoidal shape.

Preferably, as shown in fig. 2, the first protrusions 500 of two adjacent annular convex belts are axially offset from each other, so that the extrusion gap 400 can automatically desorb the viscous material.

Preferably, the radius of curvature of the first surface body 200 is larger than the radius of the pressing roller body 100. For example, the first surface body 200 is a plane body whose curvature radius is positive infinity. As another example, the second surface body 200 is a curved surface body, such as a circular arc curved surface, whose radius of curvature (i.e., its radius) is larger than the radius of the pressing roller body 100.

Preferably, the first surface body 200 is provided with the second protrusions 600, the second protrusions 600 can move relative to the roll surface when the extrusion roll body 100 rotates, and the effect of soil desorption of dung beetles or the self-cleaning effect of the lotus surface can be simulated, so that the viscous material can be automatically desorbed from the second surface body 200. Preferably, the second convex body 600 is a solid of revolution formed by a smooth curve revolution.

Preferably, as shown in fig. 1, the first plane body 200 is capable of moving radially relative to the pressing roller body 100. One side of the first body 200 is provided with a hydraulic telescopic mechanism to adjust the width of the extrusion gap 400. The hydraulic telescopic rod is connected to the non-extrusion face of the first body 200, which adjusts the width of the extrusion gap 400 when the hydraulic telescopic rod is extended or shortened.

Preferably, the first protrusions 500 have a protrusion height of not more than one third of the extrusion gap 400. For example, the protruding height of the first protrusions 500 is 2mm, and the width of the extrusion gap 400 is 8mm, 10mm, or the like.

Preferably, the other side in the radial direction of the pressing roller body 100 has a clearance gap 1000 with the second body 300. The second surface body 300 is mainly used for further cleaning the residual viscous materials on the roller surface. The radial width of the clearance gap 1000 is less than the radial width of the extrusion gap 400. Preferably, the second body 300 is provided with a third convex body 700. The third convexities 700 protrude the second convexities 300 in such a manner not to contact the pressing roller body 100. The third convex body 700 may be a solid of revolution formed by a smooth curve revolution.

Example 2

The transmission mechanism comprises a motor and a speed reducer. The motor drives the speed reducer, and the speed reducer drives the extrusion roller body to rotate. The extrusion device also comprises a machine shell, and the machine shell provides an accommodating cavity for the extrusion roller body. The first and third planes 200 and 300 may be oppositely disposed cabinet walls. Wherein the first body 200 can move in the receiving cavity. Therefore, as shown in fig. 1, a housing chamber of the hydraulic telescoping mechanism is provided in the housing. The upper part of the machine shell is provided with a feeding funnel which is arranged at one side close to the extrusion gap 400. The bottom of the machine shell is provided with a discharging box. The outer side of the bottom of the machine shell is provided with a supporting upright post.
