Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 shows a schematic structure of a batch type semi-automatic flotation separation system provided by an embodiment of the present invention, and only a part related to the embodiment of the present invention is shown for convenience of explanation.

As shown in fig. 1, the semi-automatic flotation separation system of intermittent type formula that this embodiment provided includes letter sorting container 1, contain separation miropowder 21 in the letter sorting container 1, hanging basket 3 has still been placed in the letter sorting container 1, there is the aperture on hanging basket 3 surface, a plurality of air nozzles 11 of the dense distribution in letter sorting container 1 bottom, semi-automatic flotation separation system of intermittent type is used for sorting the sorting material of two kinds of density sizes, the density of separation miropowder is between these two kinds of sorting material densities, the aperture of the aperture on hanging basket surface is greater than the particle diameter of separation miropowder, and is less than the particle diameter of two kinds of sorting materials.

In this embodiment, the density of the separated micro powder is less than that of the high-density fraction and greater than that of the low-density fraction. Generally, the high-density fraction is copper particles 22, the low-density fraction is aluminum particles 23, and the separated micropowder is iron micropowder (or ferrosilicon micropowder).

The particle size of the separated micro powder is far smaller than the aperture of the small hole of the hanging basket, so that the separated micro powder can freely enter and exit the hanging basket. During operation, pour the mixed sorting material of copper granule and aluminium granule into and hang the basket, the air cock gas injection work of letter sorting container bottom, the spun gas makes the copper granule, aluminium granule and separation miropowder scatter in hanging the basket, thoughtlessly move, and can realize the layering automatically under the action of gravity, after the nozzle stop work, three kinds of materials divide into the three-layer naturally, the upper strata is the aluminium granule, the intermediate level is the separation miropowder, the lower floor is the copper granule, accomplish once layering back, artifical or mechanical mode takes out the aluminium granule on upper strata, then continue to pour copper aluminium granule mixture into toward hanging the basket, the layering of continuing to blow, get the material back through layering many times, generally need 10 cycles. The hanging basket is taken out integrally, in the taking-out process, the separated micro powder in the hanging basket automatically falls back to a sorting container from small holes of the hanging basket, the rest copper particles are basically remained in the hanging basket, the sorting of two copper and aluminum particle sorting materials is realized, the sorting mode is simple, and the sorting effect is good.

The separating micro powder arranged in the invention is used as an intermediate layer of two sorting materials, if no separating micro powder exists, a transition layer exists between copper and aluminum particles, and the transition layer is a copper and aluminum particle mixture, so that the upper layer aluminum particles cannot be completely taken out. Through setting up the separation miropowder, even get upper aluminium granule and have got a little separation miropowder incidentally, because the particle diameter of separation miropowder is very little, getting the aluminium granule in-process, the separation miropowder also can leak to hanging in the basket.

Furthermore, in order to facilitate the two sorting and separation of micro powder to be layered as soon as possible, a vibration mechanism can be arranged to drive the hanging basket to vibrate. As a concrete structure, as shown in fig. 2-4, two hanging lugs 31 are respectively installed on the left and right sides of the hanging basket 3, a track 6 is further arranged above the sorting container, the intermittent semi-automatic flotation sorting system further comprises a pulley 7, traveling wheels 71 are arranged on two sides of the pulley 7, a control box 72 is arranged above the pulley 7, the traveling wheels 71 are located on the track 6, a hydraulic cylinder 73 and two telescopic arms 8 are vertically and downwardly arranged at the bottom of the pulley 7, a bearing plate 74 is fixed at the tail end of the hydraulic cylinder 73, the tail ends of the telescopic arms 8 are also fixed with the bearing plate 74, the vibration mechanism comprises a connecting rod pair 4 arranged at the left end and the right end of the bearing plate, a driving motor 91 arranged on the bearing plate and a rotating shaft 92 arranged in the bearing plate, two ends of the rotating shaft 92 extend out of the bearing plate, a first bearing 93 is sleeved between the rotating shaft and the bearing plate, a second bearing 94 is arranged outside the first bearing 93, the link pair 4 comprises a long link 41, a short link 42 and a middle link 43, one end of the long link 41 is hinged to one of the hangers, the other end of the long link is sleeved outside the second bearing 94, one end of the middle link 43 is hinged to the other hanger, the other end of the middle link is hinged to one end of the short link 42, the other end of the short link 42 is fixed to the tail end of the rotating shaft 92, a first bevel gear 95 is further arranged in the middle of the rotating shaft 92, an output shaft of the driving motor 91 is provided with a speed reducer, an output shaft of the speed reducer is provided with a second bevel gear 96, and the second bevel gear 96 is meshed with the first.

When the hydraulic cylinder works, the bearing plate and the hanging basket can be driven to integrally move up and down. In this embodiment, the telescopic boom 8 includes a main boom 61, a secondary boom 62 and a stop nut 63, the main boom 61 is fixed at the bottom of the pulley, the main boom 61 is provided with a guide groove, such as a dovetail groove or a T-shaped groove, along the length direction, the secondary boom 62 is located in the guide groove, the side surface of the main boom is further provided with a long-strip stop groove 64, and the stop nut 63 passes through the long-strip stop groove and is screwed and fixed with the secondary boom 62.

When the air tap at the bottom of the sorting container works, the driving motor 91 works to finally drive the short connecting rod 42 to rotate, so that one end of the hanging basket is driven to reciprocate up and down, and the scattering and layering of various materials in the hanging basket are facilitated. After layering and taking the upper material for many times, the hydraulic cylinder returns, the whole hanging basket is taken out, and in the taking-out process, the separated micro powder in the hanging basket automatically falls back to the sorting container from the small holes of the hanging basket. Then the walking wheel work, the whole track removal that moves along of device, when hanging the basket and moving to the target location, for example retrieve storehouse, pay-off transmission band etc. will hang the interior sorting material of basket and pour out can. In this embodiment, hang the basket bottom and be the bottom plate, the bottom plate pivot is connected in hanging basket bottom one side, and the bottom plate passes through locking structure to be fixed to hanging basket bottom another side. The locking mechanism is directly loosened, the bottom plate is completely opened, and the selected materials in the hanging basket fall to the target position.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
