Description

Side ore feeding forced-diversion ore distribution gateless valve ore distributor Technical Field The invention relates to the technical field of ore separators, in particular to a gateless valve ore separator with forced shunt ore distribution for side ore feeding. Background In the ore dressing production flow, the ore separator is used as core equipment for ore pulp distribution, and directly determines the feeding stability and the operation efficiency of the subsequent grinding, flotation, gravity separation and other procedures, wherein the side ore feeding mode is widely applied to various rock gold ore and iron ore dressing production lines due to the fact that the side ore feeding mode is adapted to the compact layout of a mountain area ore dressing plant, the limited equipment installation space and other scenes. Currently, main flow in industry is an ore separator with gate valve regulation, the main structure of the ore separator comprises a plurality of parallel ore separation branches with evenly distributed bottoms, each branch inlet is matched with a flat gate valve assembly, the assembly consists of a flat valve core, a valve body channel matched with the branch and an adjusting rod, ore pulp flows to each ore separation branch inlet by means of gravity after entering the ore separator through a chute, an operator changes the position of the valve core by means of the adjusting rod, scaling of a branch circulation gap is realized, further, the flow of ore pulp of each branch is controlled, and finally the ore pulp flows into subsequent equipment after being distributed according to the gate valve opening. However, in the actual side ore feeding working condition, the ore pulp flowing at high speed directly impacts the inner side wall surface of the ore separator after being conveyed by the chute, the ore pulp impact inertia and the wall surface rebound effect influence that the shunt ore discharge quantity below the side wall is 30% -50% higher than that below the feeding end, so that the shunt ore pulp is seriously unevenly distributed, the feeding load of the follow-up equipment such as a shaking table, a ball mill and the like is unbalanced, the condition of insufficient selection or idle equipment is directly caused, the useful mineral loss and the ore dressing grade fluctuation are directly caused, the ore separator is adopted by a gold ore selecting factory for carrying out side ore feeding operation, and in the actual operation, the high-flow ore pulp continuously washes a flat valve core and a sealing element, so that the sealing element needs to be replaced 2-3 times per month, the valve core abrasion rate is improved by 5-8 times than that of the normal working condition, and the maintenance cost of the valve core and the sealing element is increased by ten thousands yuan per month; meanwhile, fine-fraction particles in ore pulp are easy to pool at the gap between the valve core and the valve body to form a compact ore slurry layer, manual cleaning is carried out at least by stopping for 1 time per week, each cleaning time is 2-3 hours, and productivity loss caused by stopping cleaning per month reaches 10-15%, so that the application aims to solve the problems that ore distribution is uneven and ore dressing stability is seriously affected due to the fact that high-speed ore pulp impacts the wall surface of a diverter when side ore feeding is carried out, and meanwhile, the high-flow ore pulp aggravates abrasion of the valve core and a sealing element, and is easy to pool at a valve gap to block a pipeline, frequent stopping cleaning is needed and continuous operation efficiency is restricted. Disclosure of Invention In order to overcome the problems that when a side ore feeding mode is adopted, high-speed flowing ore pulp is conveyed to the inside of a diverter through a chute, the high-speed flowing ore pulp directly impacts the inner side wall surface of the diverter, the impact inertia of the ore pulp and the rebound effect of the wall surface are influenced, the shunt ore discharge quantity below the inner side wall surface of the diverter is obviously more, the shunt ore discharge quantity below an ore pulp feeding end is obviously less, the uniform ore distribution effect of each shunt can not be finally realized, the stable operation of the subsequent ore dressing process is seriously influenced, meanwhile, the valve core and a sealing element are continuously flushed by high-flow-rate ore pulp, the abrasion of parts is easily caused, the maintenance and replacement frequency is high, the ore pulp is easy to generate a siltation phenomenon in a gap area between the valve core and a valve body, and further the ore component branch pipeline is blocked, the manual cleaning operation is required to be stopped and the continuous operation efficiency of the ore dressing process is seriously influenced. The invention has the technical scheme that the valve-free ore separator com
