Description
Technical Field
The utility model belongs to the technical field of mineral processing equipment, a give ore deposit pipeline structure is related to, specifically a give ore deposit pipeline structure and inflatable flotation device.
Background
In the prior art, the feeding pipe is made of pure wear-resistant rubber and has high flexibility. When the new and old ore feeding pipes are replaced, the pipe hoops clamping two ends of the old ore feeding pipe are loosened, then the left and right end parts of the old ore feeding pipe are forcibly taken off from the respective extending pipe heads of the air cylinder and the ore coming short pipe by adopting combined manpower, and then the new ore feeding pipe is replaced. The reason why the assembly and disassembly can be carried out independently under the forced operation of the assembly and disassembly is that the assembly and disassembly always generates the deformation and bending of the restorable middle section in the process of assembly and disassembly due to the larger flexibility.
Although the ore feeding pipe with high flexibility is beneficial to realizing independent disassembly and assembly, the ore feeding pipe has a fatal defect in the using process, namely negative pressure in the environment in the ore feeding pipe can exert strong radial suction on the inner wall of the ore feeding pipe, and the ore feeding pipe is gradually flattened and deformed in the middle section of the ore feeding pipe along with the lapse of time, the effective flow guide section of the ore feeding pipe can be compressed by the flattening deformation, and the normal operation of flotation operation can be blocked in serious cases; in order to eliminate the serious flattening deformation of the middle section of the ore feeding pipe and further form the driving condition again, the recovery is carried out through a series of maintenance procedures such as stopping, ore drawing, flushing, correcting and the like.
In order to eliminate the harm caused by flattening deformation, an endoplasmic reticulum framework is additionally arranged in the ore pipe structure so as to enhance the rigidity of the ore pipe structure. The materials of the modified left and right ends of the feeding pipe within the respective limited range of 110 and 150 still retain the original pure wear-resistant rubber, so that the installation of the two ends of the feeding pipe is facilitated; and the inner net framework is additionally arranged in the middle section wear-resistant rubber of the large part, so that the flexibility is reduced, the rigidity is enhanced, and the original flattening deformation problem is well solved. However, such a modification creates a new difficulty, i.e., the middle section of the feeding pipe with enhanced rigidity is difficult to bend, so that the independent disassembly and assembly cannot be realized. Because the modified ore feeding pipe is difficult to bend, the main shaft part needs to be matched by moving left and right at a certain distance when the ore feeding pipe is disassembled; in order to enable the main shaft part to move leftwards integrally, bolt groups between the stator and the stator support and between the bearing body and the rack are firstly removed, then a pipe hoop fastened at the left end of the ore feeding pipe is loosened, and then the main shaft part is forcibly pulled to move leftwards integrally by a bridge crane sling, so that the left end of the ore feeding pipe 4 can be pulled off from a pipe head extending out of the air cylinder; when a new ore feeding pipe needs to be replaced, the processes need to be implemented in all reverse directions, the maintenance process is complicated, and the main shaft part moves leftwards and rightwards integrally and has considerable danger (a sling cable is pulled obliquely and is pulled hard, a bearing body collides with a frame, an air cylinder collides with a groove wall and the like usually exist).
