Embodiment

Identical in refer to the attached drawing, the several embodiments and accompanying drawing that show and describe using some reference markers or The corresponding part of person.In different embodiments corresponding component is indicated with lowercase.To the various forms shown in accompanying drawing It is described with the corresponding component of function.It should be appreciated that the variant in embodiment is generally possible to mutual phase inversion without departing from not The present invention.

Fig. 1 is shown for handling mining industry material, medicine company material, industrial materials and the DVMF10 of food industry material.Through place The material of reason must normally keep drying and typically comprise small ferromagnetism and paramagnetism impurity, and DVMF is needed institute State impurity removal.Most of described material is small not free-flowing.DVMF10 includes canister assembly 12, and it is suspended on spring In suspension 14.As dried powder is by canister assembly 12, vibratory driver 16 causes spring suspension 14 to wave canister assembly 12.It is this The device for providing and separating dried powder is provided.As canister assembly 12 is waved by vibratory driver 16, the stacking in DVMF10 Matrix heap 22 is magnetized to attract and remove ferromagnetism and paramagnetic impurity in the material by canister assembly 12.Here institute The system stated focuses on the separation of drying material, while it is expected that it can be successfully applicable to highly viscous mud.

Fig. 2 is the exploded view of canister assembly 12, and canister assembly includes tank 18 and adapter 20, and the adapter allows canister assembly 12 to pacify It is filled to DVMF10.Canister assembly 12 fixes the matrix heap 22 (figure 3 illustrates) of stacking, and the matrix heap includes several magnetisable matrixes Grid 24 (is discussed in detail below).In this embodiment, increase matrix cover 26 is so as to allow the matrix heap 22 of stacking whole Installed from DVMF10 and remove to clean and change body.The arrangement increase of this matrix heap 22 comprising stacking is available Cross-sectional area and the throughput for improving dried powder product.It there may be its that be secured in place the matrix heap 22 of stacking His method.

As shown in FIG. 3, the matrix heap 22 of stacking includes several magnetisable matrix grids 24, and described matrix grid is located at Top of each other.Fig. 4 shows the stereogram of tank 18.Tank 18 includes hollow cylinder 28 and with flanged top 30, should Flanged top is equipped with one group of bolt 32 for being used for that matrix cover to be attached to DVMF10.As seen in Figure 1, tank 18 is direct It is attached to DVMF10 body and is connected to spring suspension 14 and vibratory driver 16.

Fig. 5 shows the stereogram of matrix cover 26, and described matrix covers on the matrix heap for being installed on and stacking being fixed when in DVMF10 22.Matrix cover 26 includes fixing pipe 34, sets in the hollow cylinder 28 that the size of the fixing pipe makes it slide into tank 18.Matrix Cover 26 also includes a series of flange 36 with bolt openings 38.Flange 36 allows matrix cover 26 to be placed on the top of tank 18. When DVMF10 is assembled completely to be finished, bolt openings 38 are alignd with the bolt 32 of tank 18 so as to which bolt 32 is by bolt openings 38 and flange 36 and flange top 30 dispose together.Setting the size of the matrix heap 22 of stacking fits the diameter of itself and fixing pipe 34 Match somebody with somebody.In the embodiment depicted in fig. 5, the bottom inward curl 40 of fixing pipe 34 is so as to reduce the diameter of fixing pipe 34 and prevent The matrix heap 22 of stacking is slided and passed.This to make the matrix heap 22 of stacking fast by simply removing and replacing matrix cover 26 Speed and simply from DVMF10 remove and change.Other devices can be used for the matrix heap 22 of fixed stacking.

The stereogram of Fig. 6 display adapters 20, the adapter covers canister assembly 12.Set the chi of the adaptor body 42 It is very little it is fitted in fixing pipe 34 and is placed in just on the matrix heap 22 of stacking in the canister assembly 12 that assembling is finished.On Flange 44 has a series of screw elements 46 alignd with the bolt 32 on tank 18.Adapter 20 is fixed to tank 18 by screw element 46 And seal canister assembly 12.

As shown, Fig. 7 shows the top view of magnetisable matrix grid 24, Fig. 8 show cross section planes.By compare Fig. 7 and Fig. 8 can be best understood by, and each magnetisable matrix grid 24 includes the peripheral ring 48 with several cutting pipes 50, the cutting Pipe sets and is fixed into and is adapted within peripheral ring 48.As shown in fig. 7, peripheral ring 48 is the pipe with the first length, each cut Pipe cutting 50 has the second length less than the first length, so that each cutting pipe 50 is single on the length direction within peripheral ring 48 Layer ground is set so as to the cross section full of peripheral ring 48.Length difference at the outer rim of peripheral ring 48 and the top of each cutting pipe 50 and Gap 52 is formed between bottom.Each cutting pipe 50 is attached at least one other cutting pipe 50 or is attached to peripheral ring 48.This can be by that will complete spot welding that matrix is fixed together or other devices.

Following characteristic is critically important to the function of magnetisable matrix grid 24：Ferromagnetism, sharp edges, surface area, assembling are close Degree, structural integrity, cost and product stream flux.It is ferromagnetic in the case where using mild steel or 400 series (iron element) stainless steel Characteristic is more satisfactory, but must be suitably using mild steel or 400 series (iron element) stainless steel.By magnetisable matrix grid 24 layer is stacked together securely to enable to magnetic lines of flux to shunt without there is gap between them.It is this in order to prevent Situation, each magnetisable matrix grid 24 in the matrix heap 22 of stacking has the friendship of ferritic stainless steel and austenitic stainless steel For the peripheral ring 48 of material.Gap 52 also prevents from shunting and increasing magnetic separation.Each cutting pipe 50 forms many magnetic separation points, and its is strong Change the possibility of Magnetic Isolation.Circular cutting pipe 50 is used to providing magnetic separation point, but can alternatively using it is such as square, The simple available pipe of rectangle or other shape of cross sections.

Fig. 9 to Figure 11 shows the magnetisable matrix grid of prior art, and they are bar type lattice (Fig. 9), the honeycomb of structuring Shape (Figure 10) and the wire netting (Figure 11) of expansion.Many tests have shown that the magnetisable matrix of cutting tubular type (Fig. 7) Benefit of the grid compared with the wire netting (Figure 11) and bar type lattice (Fig. 9) that deploy.

By reference to multiple preferred embodiments, present invention is described.When reading and understanding explanation above, it will There is a variety of modification modes and mode of texturing.It should be understood that the present invention includes all these modes of texturing and modification mode, as long as These modes of texturing and modification mode are within the scope of the equivalent way of appended claims or these claims.
