Abstract
The utility model discloses an ore pulp multipoint feeding pipe network which comprises a slurry pump. An inlet and an outlet of the slurry pump are respectively communicated with a pump tank through circulation pipelines to form an ore pulp circulation loop, a non-return valve is connected onto the circulation pipeline at an outlet end of the slurry pump, and a plurality of feeding branches in parallel connection are connected onto the circulation pipeline behind the non-return valve. Each feeding branch comprises an automatic control valve and a vibrating screen which are communicated with each other, and an inlet of each automatic control valve is communicated with the circulation pipeline at the outlet of the slurry pump through a pipeline. A multipoint uniform pressure feeding mode of ore pulp is realized by matching a pressure circulation pipe network with valve control, the disadvantages of absence of steady pressure, large configuration limitation and rapidly settling material disposal ineffectiveness of the prior art can be effectively made up, the problems of multipoint feeding unbalance, rapid settling, easiness in pipe plugging and the like are solved, proper working conditions are provided for follow-up process equipment for site selection, and the ore pulp multipoint feeding pipe network has quite practical significance for improving the working efficiency of the whole site selection equipment.
Description
Technical field
The utility model relates to a kind of ore pulp feed pipe network, is specifically related to a kind of ore pulp multiple spot feed pipe network.
Background technique
Ore magma conveying method can be divided into two kinds substantially: pulp gravity flow is carried and ore pulp power is carried.The certain geometry discrepancy in elevation of gravity flow process need, requires comparatively harsh to landform; Ore pulp power is carried need to be by feed pump, and the method strong adaptability, is not limited by landform, and application area is wider.
In the ore pulp power course of conveying of free settling class material, the mode of many configurations in parallel of equipment has proposed specific (special) requirements to ore pulp feed, and equipment component working procedure also needs certain feeding pressure.The current ore pulp distribution system in the world is useful on the pulp distributer of cyclone separator at present, is useful on the pulp distributer of high frequency fine screen.The former requires have higher requirement, the latter to be generally 1 point 5 to feed, and two-stage is distributed can reach 1 point 10.Although can complete in theory the multiple spot feed of ore pulp, have following problem: 1, can not guarantee uniform and stable feeding pressure, cause needing the equipment of material feeding pressure cannot reach suitable operating mode, greatly reduce its operating efficiency; 2, the ore pulp that the material that proportion is high, material concentration is low and sedimentation is fast forms easily produces precipitation in course of conveying, stops up ore slurry pipeline; 3, material feeding point is greater than in 5 multiple spot sub-material process, and the required large discrepancy in elevation of traditional ore pulp distribution device is subject to spatial constraints.
Model utility content
The object of the utility model content is to provide the ore pulp feed pipe network of a kind of multiple spot feed equilibrium.
The disclosed this ore pulp feed pipe network of the utility model, comprise slag stock pump, its gateway is communicated with respectively formation ore pulp circulation loop with pump pond by circulating line, on the circulating line of slag stock pump outlet end, be connected with check valve, on check valve circulating line below, be connected with the feed branch road of some parallel connections.
Described feed branch road comprises the autocontrol valve and the vibrating sieve that are interconnected, and the entrance of autocontrol valve is communicated with described slag slurry delivery side of pump circulating line by pipeline.
Described autocontrol valve is electric abrasion resistance valve.
Described slag stock pump is Horizontal slurry pump.
Described vibrating sieve is mining spin vibration sieve.
The utility model is realized the mode of ore pulp Multipoint Uniform pressurized feeding by the gate control of pressures cycle pipe network proportioning valve, can make up well prior art feed large without steady pressure, configuration narrow limitation, rapid subsidence material is processed to the inferior positions such as ineffective, the problems such as multiple spot feed is unbalanced, the fast easily plugging of sedimentation are solved, for the subsequent technique equipment that selects factory provides suitable operating mode, there is very real meaning to improving the working efficiency of whole concentrator equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Preferred embodiment, the multiple spot feed by the utility model for wollastonite material ore pulp.
As shown in Figure 1, the disclosed this ore pulp multiple spot feed pipe network of the utility model, comprises slag stock pump 2, and its gateway is communicated with pump pond 1 by circulating line 3 respectively, forms an ore pulp circulation loop.On the circulating line 3 of slag stock pump 2 outlet end, be connected with check valve 4, on check valve 4 circulating line 3 below, be connected with the feed branch road being made up of autocontrol valve 5 and vibrating sieve 6 of some parallel connections, the entrance and exit of autocontrol valve 5 is communicated with circulating line and the vibrating sieve 6 of slag stock pump outlet end by pipeline respectively.
Slag stock pump 2 is adopted as Horizontal slurry pump, autocontrol valve 5 adopts electric abrasion resistance valve, vibrating sieve 6 adopts mining spin vibration sieve, and its parameter type selecting can propose corresponding requirements to manufacturer according to different materials, and slag stock pump 2 its lift in the time of type selecting need be considered certain surplus.
The working principle of the present embodiment is as follows: wollastonite material is through after a series of processing such as broken, superfine grinding and iron removal by magnetic separation, for reducing the impurity contents such as calcite wherein, improving its industrial value, also needs to feed spin vibration sieve and carries out wet separation purification.According to the beneficiation test result of this wollastonite, the operation concentration that gravity treatment and screening require is very low, causes these two kinds of device fabrication quotas very low, therefore the gravity treatment classifying equipoment of selecting and screening equipment for purifying number are huge, exceed 80 feeding points, and wollastonite material sinking velocity is fast.In this process, in order to overcome wollastonite fibre rapid subsidence to industrial adverse effect, take into account the steady pressure feed of vibrating sieve 6 simultaneously, feed adopts 2 superchargings of slag stock pump to carry: ore pulp is communicated with and forms with each ore pulp circulation loop from pump pond 1 by circulating line 3 and slag stock pump 2, slag stock pump 2 is raised ore pulp to deliver in circulating line 3, between the vibrating sieve 6 of circulating line 3 and each point branch road in parallel, pass through pipeline communication, adjustable in order to guarantee material feeding pressure and the material feeding amount of vibrating sieve 6 in each parallel branch, between vibrating sieve 6 and the circulating line 3 of slag stock pump 2 outlet end, connect autocontrol valve 5 and control flow and the pressure of each branch road.The switching degree that whole feed process can regulate and control each valve by instrument is carried out the flow of all pipelines of controlled circulation pipe network, guarantee that each material feeding point provides stable pressure, flow, to guarantee all and feeding coal uniformities suitable with the required feeding pressure of equipment of material feeding pressure of vibrating sieve 6 all in parallel of simultaneously operation.
The utility model especially adapts to the multiple spot feed of free settling class material ore pulp.
