Description

Mining equipment for soluble mine with hose diverter

The utility model belongs to the winning equipment in the solvable ore deposit of drilling well production by dissolving and leaching process.

The solvable ore deposit of drilling well production by dissolving and leaching process (comprising mineral such as salt, alkali, alum and saltcake) has two kinds of mining codes of individual well convection current and twin-well (or many wells) pressure burst communicatin usually.Existing individual well convection current winning equipment is mostly formed by adopting halogen tree, protective casing, central tube etc., no matter be the direct circulation exploitation, still anti-circulation exploitation, the shaft bottom delivery port and get the halogen mouth all coexist one manage the string bottom, only in height keep certain distance, and this is apart from the restriction that also is subjected to seam thickness, causes " two oral regions " to become the low dense district of persistence.It is low not only to adopt halogen concentration, and it is fast to go up molten speed, causes the too early exposure of top board easily to collapse.Because molten chamber upper layer side is molten fast, lower layer side is molten slow, and the development of molten chamber is back taper (A district as shown in Figure 4), and laterally molten soaking is restricted, so well yield is few, the length of service is short, and recovery ratio is low.

Task of the present utility model just is to design the winning equipment that a kind of fresh water is delivered directly to molten of side and can expands molten chamber in the ore bed bottom transverse, reaches to increase and adopts halogen concentration, prolongs length of service, and improves the purpose of well yield and recovery ratio.

Winning equipment of the present utility model is shown in accompanying drawing 1,2,3, it comprises water inlet pipe (1), go out halogen pipe (2), protective casing (3), central tube (4), adopt the halogen tree by four-way connection (5) and formations such as (6), at water inlet pipe with go out the halogen pipe and adopt between the joint of halogen tree by-pass valve control (7) is housed, the most outstanding feature of winning equipment of the present utility model is that fresh water dispenser (8) is equipped with in the shaft bottom, pack in the annular space (annular space between pipe) between central tube and the protective casing in its upper end, the lower end links to each other with central tube through jaw clutch (9).Fresh water dispenser has that annular space communicates between an axial circular passage (23) and pipe, there are 2 above radial junctions (24) that the flexible pipe (10) of circumferentially extending is housed, fresh water by annular space is diverted to after fresh water dispenser is distributed to flexible pipe away from around the central axis, and the distance of getting halogen mouth and delivery port is by horizontal open.Described flexible pipe can be changed, and this distance can extend with the expansion in molten chamber.Another prominent features of the present invention is, has a screen casing (11) to be connected with central tube by interior connection hoop (12), has sieve aperture (13) on the screen casing, by four-way connection (6) with screen casing and central tube with water inlet pipe or go out the halogen pipe and be communicated with.Described screen casing joins through power transmission shaft and actuating unit, makes the rotation of central tube do around its axis.Thereby drive flexible pipe and make circular motion, constantly the ore bed bottom to around the molten chamber of horizontal expansion.In order to guarantee that central tube effectively rotates, a boss (14) is arranged on the screen casing, thrust bearing (15) and adjustable sealing device are housed on the screen casing.Described sealing device is made up of airtight and watertight padding (16), filler cover (17) and gland (18), and the filler cover also works to be connected two four-way connections with gland.Fresh water dispenser is to change by the positive and negative direction that circulates in the pressure differential of distributor two ends formation to realize along the lifting of annular space between pipe.For this reason, one-way cock is housed in the fresh water dispenser, it is made up of fixed valve base (19) valve block (20), supporting fork (21), movable valve seat (22).In distributor, also be provided with the mechanism of controlling non-return valve action message, it comprises voussoir (38), spring leaf (39), tapered bar (40), flexible pipe is with collapsible, the intensity height, thickness is little, fluid-tight flexible material manufacturing, in order to change conveniently, install on the radial junction of fresh water dispenser by jump ring (25).Described flexible pipe collapsible back when fresh water dispenser is transferred the shaft bottom is beaten with restricting on the tail pipe (26) that movable joint is bundled in fresh water dispenser, be equipped with in this tail pipe bottom and separate rope mechanism, it comprises a supporting base (27) and two earrings (28) that are installed on the fresh water dispenser tail pipe, (29), adorn a rope sheave (30) on the supporting base, pass a Γ shape tappet (31) in two earrings, stay cord (37) is walked around rope sheave and is linked to each other with tappet top, the Xie Jieduan of aforementioned movable joint (32) links to each other with stay cord, central tube (4) relative distribution device after the shaft bottom end has to have the flange of the scallop (34) that forms jaw clutch is up, it is drop-down to drive stay cord (37), untie movable joint, the water filling rear hose is just extensible.For dismounting, repair fresh water dispenser and change flexible pipe convenient, standpipe (35) is housed with adopting halogen between setting at protective casing, have rectangular opening on it, it is covered by seal cover board (36).

Adopt winning equipment of the present utility model can fundamentally improve the molten condition of soaking, make the favourable variation of CONCENTRATION DISTRIBUTION generation in the molten chamber, can not only improve and adopt halogen concentration, and can improve recovery ratio.Under the condition of no oil or air cushion, (do not repel with lubricating pad or air cushion yet and be used) and controlled molten speed, prolonged the length of service.Because can enlarge molten chamber in the ore bed bottom, molten cavity configuration is improved, and becomes the positive taper shown in the B district among Fig. 4 by the back taper shown in the A district among Fig. 4, has improved anti-ground pressure energy power, can improve well yield, reduces the drilling engineering amount.Winning equipment of the present utility model is used for twin-well or many wells unitized production, can accelerates the molten speed of bottom ore deposit side, realize the early stage connection in ore bed bottom.Being used for the individual well initial stage builds groove, can shorten and build the groove phase, and the enlarged slot footpath reduces the groove height, and just can produce dense halogen building the groove phase.Winning equipment of the present utility model is applicable to exploitation ore deposit, deep or superficial part ore deposit, individual layer ore deposit or multilayer ore deposit, and Yi Rong ore deposit or indissoluble ore deposit adopt winning equipment of the present utility model can also utilize discarded old well to reclaim the ore deposit, bottom, and Fig. 4 is exactly a schematic diagram.
