Description

Technical Field

[0001] The utility model relates to the technical field of ore washers, in particular to a sealing device for a trough type ore washer. Background Art

[0002] The lime-deionized calcium carbide slag pulping production process is to transport the calcium carbide slag to the production site by road and then use a trough type ore washer to remove the slag and make pulp. During the calcium carbide slag pulping operation, due to the needs of the production process, the trough washer is changed from horizontal installation to angle installation. Therefore, the special working nature of the equipment is that the slag removal operation is carried out at the higher end of the equipment, and the mixing overflow operation is carried out at the lower end. Therefore, the sealing effect of the equipment at the lower end directly determines whether the equipment can operate efficiently and is the key to whether the production process can operate continuously and stably.

[0003] Conventional trough-type ore washing machine equipment uses packing seals or mechanical seals for sealing. In the actual production process of calcium carbide slag pulping, the working range of the stirring shaft is wide and the deflection of the stirring shaft is large, so the axial and radial displacements are high (displacement ≥ 5mm). In addition, due to special production conditions, the particle size deviation of calcium carbide slag is extremely large and the viscosity is high. The waste slag contains various rubber, iron and other debris, which causes severe wear of the packing of the on-site equipment when using the packing sealing structure, causing the problem of seal failure to become normalized. The existing sealing structure cannot meet production requirements. Frequent leakage of equipment seals leads to a linear increase in the mechanical failure rate, which not only increases the inspection, maintenance and cleaning costs, but also seriously affects the continuous and stable operation of the production process.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1-3 As shown, a sealing device of a trough type ore washing machine includes a stirring shaft 8 and a sealing device arranged on the stirring shaft 8, the sealing device includes a supporting assembly, a sealing ring 3 and a cone sleeve 6, the sealing ring 3 is arranged inside the supporting assembly, the sealing ring 3 is elastic, the cone sleeve 6 is arranged on the stirring shaft 8, and one end of the cone sleeve extends into the supporting assembly and is tightly attached to the sealing ring 3.

[0025] like Figure 1-3As shown, the support assembly includes a support plate Ⅰ1 and a support plate Ⅱ4, one end of the support plate Ⅰ1 is directly connected to the trough-type ore washing machine, the support plate Ⅰ1, the sealing ring 3 and the support plate Ⅱ4 are all annular structures with an opening at the center of the circle, the sealing ring 3 is arranged between the support plate Ⅰ1 and the support plate Ⅱ4, the support plate Ⅰ1 is provided with a connecting hole Ⅰ101, the connecting hole Ⅰ101 penetrates the support plate Ⅰ1, the support plate Ⅰ1 is symmetrically provided with positioning holes 102, the positioning holes 102 penetrate the circumferential surface of the support plate Ⅰ1 to the center of the circle, the support plate Ⅰ1 is provided with a slide groove 103, the slide groove 103 is arranged on both sides of the positioning hole 102, the support plate Ⅰ1 is provided with a threaded hole Ⅰ106, and the positioning hole 102 can be A positioning rod 104 is provided for sliding, and the positioning rod 104 moves toward the center position of the support plate Ⅰ1. A baffle is provided at one end of the positioning rod 104, and a threaded hole Ⅱ105 is provided on the baffle. The threaded hole Ⅰ106 and the threaded hole Ⅱ105 are aligned. Pressure plates 107 are provided on both sides of the positioning rod 104, and the pressure plate 107 is provided in the slide groove 103. A spring 108 is provided in the slide groove 103 and connected to the pressure plate 107. When the positioning rod 104 moves toward the center position of the support plate Ⅰ1, the pressure plate 107 slides in the slide groove 103, and the pressure plate 107 compresses the spring 108, and screws are inserted into the threaded holes Ⅰ106 and Ⅱ105 to fix the position of the positioning rod 104.

[0026] When the support plate Ⅰ1 and the trough type ore washer are connected by bolts, once the support plate Ⅰ1 and the stirring shaft 8 are not concentric, it is difficult to align the connection hole Ⅰ101 of the support plate Ⅰ1 with the connection hole on the trough type ore washer. Therefore, in order to quickly align and install the support plate Ⅰ1, an optimized design is carried out. During installation, it is only necessary to adjust the positioning rod 104 first, and adjust the synchronous stroke of the two positioning rods 104 so that the ends of the positioning rods 104 are close to the stirring shaft 8, so that the support plate Ⅰ1 and the stirring shaft 8 can be concentric, and then the support plate Ⅰ1 can be rotated to quickly align the connection hole Ⅰ101 of the support plate Ⅰ1 with the connection hole on the trough type ore washer.

[0027] When installing the support plate Ⅰ1, adjust the positioning rod 104 so that one end of it is in close contact with the stirring shaft 8, and fix the position of the positioning rod 104. At this time, the support plate Ⅰ1 and the stirring shaft 8 are concentric, and the installation is more stable. After the centering is completed, the screw can be unscrewed, and the spring 108 rebounds to drive the positioning rod 104 to reset.

[0028] like Figure 1-3As shown, a connecting hole II41 is provided on the support plate II4, a connecting hole III31 is provided on the sealing ring 3, a connecting piece is provided between the connecting hole I101, the connecting hole II41 and the connecting hole III31, threaded sections are provided inside the connecting hole I101, the connecting hole II41 and the connecting hole III31 respectively, the connecting hole I101, the connecting hole II41 and the connecting hole III31 are aligned, the connecting piece is a bolt 2, the bolt 2 is inserted into the connecting hole I101, the connecting hole II41 and the connecting hole III31 to fix the support plate I1, the sealing ring 3 and the support plate II4, and the threaded connection is adopted, which is convenient for disassembly and assembly of the sealing device as a whole, thereby increasing the working efficiency.

[0029] like Figure 1-3 As shown, the cone sleeve 6 is connected to the stirring shaft 8, and an inner ring 5 is provided on the cone sleeve 6. The inner ring 5 is arranged at the connection position between the cone sleeve 6 and the stirring shaft 8. A tensioning sleeve 7 is provided at one end of the cone sleeve 6, and the tensioning sleeve 7 is connected to the stirring shaft 8. The inner ring 5 and the tensioning sleeve 7 make it difficult for the cone sleeve 6 to slide on the stirring shaft 8, thereby enhancing the overall sealing effect. The opening diameter inside the sealing ring 3 is smaller than the opening diameter of the support plate Ⅰ1 and the support plate Ⅱ4. The conical surface part of the cone sleeve 6 extends from the support plate Ⅱ4 to squeeze the sealing ring 3. Because the sealing ring 3 is elastic, the sealing ring 3 bends toward the position of the support plate Ⅰ1 and fits with most of the conical surface of the cone sleeve 6, so that it has a better sealing effect. When the cone sleeve 6 is displaced after long-term use, the sealing ring 3 can also move with its conical surface due to its elasticity, and continue to fit tightly to ensure the quality of the seal.

[0030] Working principle: Sleeve the support plate Ⅰ1 on the stirring shaft 8, push the symmetrical positioning rods 104 respectively to make one end of them contact with the stirring shaft 8, and screw the screws into the threaded holes Ⅰ106 and Ⅱ105 to fix the positioning rod 104. At this time, the support plate Ⅰ1 and the stirring shaft 8 are concentric. Weld the support plate Ⅰ1 to the trough type ore washing machine, install the sealing ring 3 and the support plate Ⅱ4 on the outside of the support plate Ⅰ1 respectively, align the connecting hole Ⅰ101, the connecting hole Ⅱ41 and the connecting hole Ⅲ31, and screw in the bolt 2 to fix the support plate Ⅰ1, the sealing ring 3 and the support plate Ⅱ4, insert the cone sleeve 6 into the stirring shaft 8, and extend it into the support assembly and the sealing ring 3 tightly, add the tension sleeve 7 at the end of the cone sleeve 6 to fix it on the stirring shaft 8.
