Description

Technical Field

[0001] This utility model relates to the technical field of mining washing equipment, specifically to a trough-type washing machine blade assembly. Background Technology

[0002] The trough-type ore washing machine is one of the main pieces of equipment in ore washing plants. It's a large-scale piece of equipment used in ferrous and non-ferrous metallurgical mines, steel mills, metallurgical plants, chemical plants, and building materials industries to clean ores and stones. Ore washing prevents clay-containing mineral raw materials from clogging crushing and screening equipment. Raw materials containing soluble useful or harmful components also require washing. Ore washing machines are widely used in mining, coal, metallurgy, and other industries.

[0003] In existing trough-type ore washing machines, the blades between the two main shafts are parallel. When the trough-type ore washing machine is working, it only uses the friction between the blades and the ore, between the ore and the ore, and between the ore and the side plate to remove the mud. It is difficult to break up the mud with high hardness and strong cohesion, resulting in poor washing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a blade assembly for a trough-type ore washing machine. This blade assembly, through the process of the blade surface spacing between the blades installed on two large shafts with opposite rotation directions continuously changing from large to small, first shears and squeezes the ore and mud between the upper and lower blade surfaces, and then shears and stretches them. It uses a strong force to scrub and break up the mud, thereby improving the ore washing effect of the trough-type ore washing machine.

[0005] The aforementioned trough-type ore washing machine blade assembly includes a base, a blade holder, and blades;

[0006] The rear end of the blade stalk is mounted on a base, which is used to connect to the left or right main shaft; the top and bottom surfaces of the blade are respectively provided with intersecting longitudinal and transverse protruding cylinders.

[0007] The top and bottom surfaces of the blade are both inclined, and the cross-section of the blade is a trapezoidal structure. The waist of the trapezoidal structure is located on the top and bottom surfaces of the blade. The top and bottom surfaces of the trapezoidal structure are located on the two lateral sides of the blade, respectively. The front end of the petiole is connected to the rear end of the blade in the longitudinal direction.

[0008] The blade has an isosceles trapezoidal cross-section.

[0009] The angle between the top surface of the blade and the horizontal plane is 3°-10°, and the angle between the bottom surface of the blade and the horizontal plane is 3°-10°.

[0010] The longitudinally arranged protruding cylinders are arranged along the longitudinal direction of the blade, and the transversely arranged protruding cylinders are arranged along the transverse direction of the blade.

[0011] The top and bottom surfaces of the blade stalk are provided with two or more parallel guide rails, the direction of which is longitudinal of the blade; the blade stalk is provided with multiple blade stalk locking screw holes.

[0012] The base includes a base body, base feet, and guide grooves; the rear end face of the base body is an arc-shaped surface corresponding to the left or right main shaft, and is connected to the left or right main shaft by welding; the front end face of the base body is provided with a longitudinal guide groove, and the top and bottom surfaces of the guide groove are provided with corresponding base locking screw holes; the guide groove is adapted to the blade handle, and a guide strip corresponding to the guide rail is provided in the guide groove. The blade handle is fully inserted into the guide groove, and the blade handle and base are fixedly connected by bolts passing through the base locking screw holes and the blade handle locking screw holes and tightening with nuts; the top and bottom surfaces of the base body are provided with base feet at the rear end.

[0013] The blade and petiole are integrally cast.

[0014] The blades mounted on the left and right main shafts are staggered in the axial direction of the main shafts. When the left and right main shafts rotate in opposite directions, the projections of the blades on the left and right main shafts in the axial direction of the main shafts overlap. Furthermore, the side of the trapezoidal structure of the cross-section of the blades mounted on the left and right main shafts is located in front of its rotation direction.

[0015] The working principle of this utility model is as follows:

[0016] like Figure 3 and 4 As shown, the left main shaft rotates counterclockwise and the right main shaft rotates clockwise. When two adjacent blades in the axial direction of the main shaft rotate to the overlapping area, the distance between the top surface of the blade on the left main shaft and the bottom surface of the blade on the right main shaft continuously decreases, and then they separate from each other and leave the overlapping area. The ore and mud between these two blade surfaces will first be subjected to shear force and extrusion force, and then to shear force and tensile force. At the same time, the longitudinal and transverse convex cylinders on the upper and lower blade surfaces increase the friction coefficient, thereby increasing the shear force during the entire blade surface distance change process. The powerful force is used to scrub and break up the mud, thereby improving the washing effect of the trough washing machine.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention features a uniquely structured blade assembly. Through a special installation structure on the left and right main shafts of the trough-type ore washing machine, the blade spacing between adjacent blades on the two shafts changes continuously from large to small in the axial direction. This allows the ore and mud to be sheared and compressed first between the bottom surface of the upper blade and the top surface of the lower blade, followed by shearing and stretching. The powerful force washes and breaks up the mud, thereby improving the washing effect of the trough-type ore washing machine and showing good application prospects. Attached Figure Description
