Description
Technical field
This utility model relates to preparation equipment technical field, particularly to a kind of spiral chute charging gear.
Background technology
Spiral chute combines the feature of spiral concentrator, cleaning table, centrifugal ore separator, thickener, is equipment indispensable in mining, mineral processing production line, is widely used in each metalloid and non-metal mine, especially applies more in terms of processing low-grade ore in sand form.
Spiral chute uses the most in groups, meets user's process demand to ore in sand form, and spiral chute is arranged in rows.Ore in sand form be by the apparatus processing of last process after, through pump or borrow flow by gravity to deliver into spiral chute beneficiating process by pipeline with the form of finite concentration ore pulp.Adjustable parameter in the productions such as spiral chute operating parameter mainly shows ore deposit quantity, feed ore concentration；Operation is mainly controlled to ore deposit quantity and feed ore concentration by the amount controlling flushing water；When sorting relatively coarse fraction, can be larger to ore deposit quantity, when processing fine fraction, want less；The feed ore concentration roughly selecting operation is lower than selected operation concentration；In practical operation, fluctuating on separation index without big impact to ore deposit quantity and feed ore concentration in the range of Appropriate ± 5%, too high or too low all can make recovery rate in ore-dressing decline to ore deposit quantity or feed ore concentration.
Ore pulp is in the duct by frictional resistance effect, and its instantaneous number and concentration have certain fluctuation, if from feed pipe directly to spiral chute mine distributor feed, spiral chute feed can be made irregular, affect sorting result, reduce the concentrate response rate.The most conventional practice is that ore pulp is first entered mine-separating box by feed pipe, then by mine-separating box by dividing pipe to be transported to the mine distributor of each spiral chute, by the feed launder in mine distributor point ore deposit to spiral chute, ore pulp enters spiral chute from feed launder；The position arranged on mine-separating box due to point pipe is different, have divide pipe in the middle of mine-separating box, have at mine-separating box edge, point pipe having is close to feed pipe road junction, point pipe having is away from feed pipe road junction, and point pipe length is different, and resistance suffered by ore pulp is the most different；Above-mentioned factor causes ore pulp flow velocity in each point of pipe to have difference.Point pipe that flow velocity is fast, the corresponding spiral chute many concentration of ore pulp supply amount is low；Point pipe that flow velocity is slow, the few concentration of corresponding spiral chute ore pulp supply amount is high.This just brings series of problems, and flow rate of pulp is fast, quantity is many, and ore pulp can overflow from spiral chute, not only pollutes working space but also can not make mineral efficient recovery；Contrary flow velocity is slow, quantity is few, and concentrate coheres affects mineral efficient recovery on cell body equally；Divide ore deposit uneven, make to utilize flushing water to regulate the operation to ore deposit quantity and concentration and do not play effect, also cannot follow change effective adjustable screw chute ore dressing running parameter of ore in sand form character, not reach and most preferably sort recovering effect.
Utility model content
In order to make up the deficiencies in the prior art, this utility model provides a kind of point ore deposit uniform spiral chute charging gear.
The technical solution of the utility model is:
A kind of spiral chute charging gear, including the sub-feed tube 6 connected with the tripper 7 above spiral chute 8, the other end of described sub-feed tube 6 connects distribution box 3 and is arranged at the bottom of described distribution box 3；Described distribution box 3, sub-feed tube 6 all with spiral chute 8 one_to_one corresponding；Each described distribution box 3 is both secured to mixer 2, and each described distribution box 3 is uniformly distributed in mixer 2 outer；Described mixer 2 connects feed pipe 1；Described mixer 2 is fixed on support 9.
Preferably, described mixer 2 is in cylinder；The inner side edge that each described distribution box 3 contacts with mixer 2 forms the regular polygon circumscribed with the casing of mixer 2；Each described distribution box 3 is end to end with the inner side edge that mixer 2 contacts is an entirety.
Further, the outer side edges the most end to end composition regular polygon that each described distribution box 3 is relative with mixer 2.
Preferably, each described distribution box 3 present wealthy under narrow infundibulate.On the one hand it is easy to ore pulp and is collected to bottom distribution box, flow out from bottom wear-resistant steel pipe and be difficult to precipitate buildup, with welding between batch mixing welding box body and each distribution box inside another aspect beneficially each distribution box.
Preferably, each described distribution box 3 outer side edges is higher than inner side edge.This structure can ensure that ore pulp does not spills over.
Further, it is provided with wear-resistant steel pipe 4 between each described distribution box 3 and sub-feed tube 6.Further, described wear-resistant steel pipe 4 is provided with gate valve 5.Arrange gate valve to be easy to control to ore deposit quantity.
Feed pipe is deep into mixer centre position, the ore pulp come from last process conveying, in cylindric mixer body, is sufficiently mixed, makes even concentration, and overflow into each distribution box from mixer outer；Distribution box is on support, and level height is higher than spiral chute tripper, makes ore pulp in distribution box have certain feed force.Owing to ore pulp is to overflow after mixing, and the once regular polygon arrangement around mixer of each distribution box, therefore can guarantee that the ore pulp entering each distribution box, quantity and concentration is essentially identical and stably.Distribution box is connected with the tripper on spiral chute by sub-feed tube, enters each distribution box ore pulp quantity identical with concentration, then the ore pulp quantity and the concentration that enter each spiral chute tripper are also the most essentially identical.
When ore in sand form character changes and needs to adjust spiral chute operating parameter, flushing water can be passed through mixer, all chute pulp densities of unified regulation；Equipped with valve on wear-resistant steel pipe bottom each distribution box, the mine-supplying quantity of each spiral chute of adjustable, it is possible to close part spiral chute when ore pulp amount is inadequate, it is ensured that spiral chute to ore deposit quantity and concentration parameter all the time in optimum recovery efficient state.
The beneficial effects of the utility model are:
This utility model ensure that ore pulp uniformly gives each spiral chute, it is thus possible to effectively control each spiral chute to ore deposit quantity and concentration, make to fluctuate in the range of Appropriate ± 5% to ore deposit quantity and concentration, it is ensured that the concentrate response rate.
