Detailed description of the invention

Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention.

In description of the present utility model, it will be appreciated that, term " longitudinally ", " laterally ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of instructions such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of device or the element of instruction or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.

In the description of this description, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.

In description of the present utility model, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, for example, can be mechanical connection or electrical connection, also can be the connection of two element internals, can be to be directly connected, and also can indirectly be connected by intermediary, for the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.

As shown in Figure 1, be the structural representation of the utility model preferred embodiment mixing device.The mixing device of the utility model particles is mainly made up of mixing tank 2, ajutage 21, discharge pipe 22, air-supply arrangement 3, separator, head tank 1, granule screening machine 4 and emptying tank 6.

Ajutage 21 is positioned at top and the connection with it of the sidewall of the tank body 20 of mixing tank 2.The mouth of pipe place face of ajutage 21 is perpendicular to the section of sidewall and mouth of pipe intersection ajutage 21 of tank body 20, can make like this wind energy entering in tank body 20 enter along the tangential direction of the sidewall of tank body 20, be subject to collision and the bounce-back of the inner surface of the sidewall of tank body 20, just can be formed at the wind of horizontal plane rotation.Be understandable that, above-mentioned description based on the prerequisite situation direction that to be wind flow out from the mouth of pipe of ajutage 21 vertical with mouth of pipe place face." mouth of pipe " is defined as near the position of body opening one section." mouth of pipe place face " can be understood as the end face of body opening part.

As shown in Figure 2, be the partial enlarged drawing of A in Fig. 1.In figure, the mouth of pipe place face of ajutage 21 and the inclination alpha of horizontal plane are 0 to 45 degree (as shown in Figure 2), make like this flow direction of the wind of being sent by ajutage 21 there is certain component at vertical direction, for wind moves downward the first speed that vertical direction is provided.

Discharge pipe 22 is communicated in tank body 20 bottoms.For the wind that makes to flow out through discharge pipe 22 can be separated particles after having enough large speed and entering separator preferably, the spout diameter of discharge pipe 22 is less than air outlet, particularly, its spout diameter blow young must be more, the speed of the wind that discharge pipe 22 flows out is just larger.

Separator is positioned at one end of the principle tank body 20 of discharge pipe 22.Separator is separated for the wind that particles is discharged from discharge pipe 22.Separator can be for being provided with the similar device of filter screen, and this kind of device can filter out particles by filter screen but wind can pass through filter screen.This example is preferably cyclone separator 5.In view of cyclone separator 5 is a kind of conventional equipment that the fields such as chemical industry separate with solid for realizing gas, its principle and concrete structure by those skilled in the art is known, are not described in detail in this.

Head tank 1 is positioned at the top of body, and is communicated with tank body 20.Head tank 1 comprises tremie pipe 11.The mouth of pipe of tremie pipe 11 is positioned at the top of the mouth of pipe of ajutage 21, the particles that so can make to flow into tank body 20 from tremie pipe 11 can fall one section just by wind to, the effect of scattering to a certain extent can be played in the whereabouts of particles.Tremie pipe 11 is provided with 111 of baiting valves, after head tank 1 charging, can open this valve.

Ajutage 21 is connected with air-supply arrangement 3.The air outlet cover of air-supply arrangement 3 is connected to ajutage 21.Air-supply arrangement 3 can be air blast, is preferably larger power, ensures that the wind providing thus has larger speed.

Granule screening machine 4 is connected in the top of head tank 1.Before to head tank 1 charging, can carry out in advance the roughly screening of granularity to particles, prevent that particle from entering tank body 20 compared with large particles rear too fast compared with falling greatly because of quality, the effect that mixed by wind is poor.This granule screening machine 4 can be the screening machine of vibration-type.

Emptying tank 6 is positioned at the below of separator, and it is attached thereto.Emptying tank 6 is for interim storing.Drain hole 61 is provided with baiting valve 611, the particles mixing can be released to other the container that particles need to be shifted from drain hole 61.

Introduce the operation principle of instrument of the present utility model below.

First, the particles after granule screening machine 4 is sieved packs head tank 1 into.After air-supply arrangement 3 to be opened, the wind moving downward in the interior formation spiral of tank body 20.Open baiting valve 111, particles is just fallen to forming to have the particles of given pace by tremie pipe 11, and the wind being moved downward by spiral in the process of whereabouts must be scattered, and the turning effort of wind can aggravate the peptizaiton of particles.Meanwhile, the effect under wind direction is discharged by air outlet with particles, then enters cyclone separator 5.The clean air that does not contain particles in cyclone separator 5 is discharged by cyclone separator 5 air outlets, and particles is fallen the urceolus bottom that is positioned at cyclone separator 5.Finally, the particles of separation is collected in emptying tank 6.

Although the above more term that represents structure that used, for example " head tank 1 ",, " mixing tank 2 ", " tremie pipe 11 ", " tank body 20 ", " air-supply arrangement 3 ", " separator ", " ajutage 21 " and " discharge pipe 22 " etc., but do not get rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.

Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, within these modes all will fall into protection domain of the present utility model.
