Abstract

The utility model relates to a ball mill mixing device, which mainly comprises an outer cylinder, an inner cylinder, an inlet, an outlet, a transmission shaft, a rib plate, a hard ball and a grating. The inner cylinder is installed and fixed in the outer cylinder. The outer cylinder and the inner cylinder are installed on the transmission shaft and driven to rotate by the transmission shaft. The rib plate is arranged on the inner wall of the inner cylinder, the grating and the hard ball are further arranged in the inner cylinder, and the grating stops the hard ball from falling off. When the ball mill mixing device rotates, after the rib plate drives the hard ball to move to a certain height, the hard ball falls into the inner cylinder by means of action of the gravity and centrifugal force to hit powder materials, so that material crushing and even stirring and mixing are achieved. The ball mill mixing device is simple in structure and utilizes the hard ball to crush the material to obtain good crushing and stirring effects. The inner cylinder of the ball mill mixing device is of a full sealing structure, and the whole crushing process is free of dust pollution. The ball mill mixing device is of a multi-layer cylinder structure, the inner cylinder is convenient to replace, and the service life of the whole ball mill mixing device is prolonged.

Description

The ball mill mixing device

Technical field

The utility model relates to a kind of ball mill, particularly the ball mill mixing device that mixes with different powders of chemical field.

Background technology

Ball mill is after material is broken, the key equipment of pulverizing again.It is widely used in industries such as cement, silicate product, construction material, refractory material, chemical fertilizer, non-ferrous metal ore and glass ceramics.At present, at chemical field, often also use ball mill, after caked powder was pulverized, the powder different with other mixed and stirs.Existing ball mill generally all is applicable to oarse-grained industrial circle, and material is joined after ball mill grinds, and gets into batch mixer again and carries out batch mixing once more, just discloses this ball mill like one Chinese patent application CN201010587566.0.But at chemical field, the particle of powder is very tiny, have in addition reach nanoscale, need this molecule be mixed fully, general ball mill can't reach actual instructions for use.In addition, when existing ball mill conducting powder minced material, the general continuous rotary operation was unfavorable for the abundant mixing of powder, also unavoidably produced dust pollution simultaneously.

Summary of the invention

The deficiency that the utility model exists to prior art just provides a kind of ball mill mixing device.

A kind of ball mill mixing device mainly comprises urceolus, inner core, flange, import and export, support, power transmission shaft, hard ball, and described ball mill mixing device also comprises gusset, and gusset is distributed in the inwall of inner core.

Described ball mill mixing device also comprises grid, and grid is arranged on the inside of inner core, and grid appearance and size is not less than import and export.

The hard ball total amount of described ball mill mixing device accounts for 5%～30% of inner core volume.

The hard ball total amount of described ball mill mixing device accounts for 10%～20% of inner core volume.

The utility model compared with prior art, the described ball mill mixing apparatus structure of the utility model is simple, utilizes hard ball to carry out particle, particle and mixing effect are good; Its inner core is a full-closed structure, whole crushing process no dust pollution; The ball mill mixing device is a multi-layer cylinder version, and inner core is convenient for changing, and improves whole service life.

The specific embodiment

To combine concrete embodiment that the content of the utility model is described below.

As shown in Figure 1, be the front view of the described ball mill mixing device of the utility model.The described ball mill mixing device of the utility model is the sandwich construction form, and it mainly comprises urceolus 1, inner core 2, flange 3, import and export 4, support 5, power transmission shaft 6, gusset 7, hard ball 8, grid 9.Inner core 2 is installed in the urceolus 1, and is fixed in the urceolus 1.Urceolus 1, inner core 2 are installed on the power transmission shaft 6, and are rotated simultaneously by power transmission shaft 6 drive urceolus 1, inner core 2.Power transmission shaft 6 two ends are supported by support 5, and support 5 is fixed on the ground 10, and the powder that supports power transmission shaft 6, urceolus 1, inner core 2 and need to mix.

Urceolus 1 and with the corresponding position of inner core 2 on, be provided with and import and export 4.When powder is pulverized stirring in the ball mill mixing device, close and be arranged on the lid of importing and exporting on 4 (not marking among the figure).Powder is pulverized in airtight inner core 2 and is mixed like this, avoids dust pollution.Simultaneously, through the rotation of control power transmission shaft 6, realize that batch-mixed stirs, it is more even that powder is mixed.

As shown in Figure 2, be the A-A revolved sectional view of the described ball mill mixing device of the utility model, import and export this moment 4 along B to being rotated to below.Inwall at the inner core 2 of ball mill mixing device evenly is provided with some gussets 7, in inner core 2, also is provided with some hard balls 8.In inner core 2, be provided with grid 9, the appearance and size of grid 9 is bigger than import and export 4, prevents that like this grid 9 from falling down from importing and exporting 4.Grid 9 is distributed with a plurality of grids, can stop hard ball 8 to fall down.

When the ball mill mixing device along B to when rotation, gusset 7 drives hard balls 8 and moves upward.After moving to certain altitude, hard ball 8 is fallen in the inner core 2 under gravity and action of centrifugal force, and pounds to powder, can very soon caked powder be pulverized like this.Because the inwall at inner core 2 evenly is provided with some gussets 7, hard ball 8 falls down after constantly eminence is taken in circulation to, and powder is hit in so continuous circulation, and different powders are mixed.

The quantity of hard ball 8 directly influences powder stirring efficiency and mixing effect.When hard ball 8 quantity were very few, the efficient that circulation is hit was lower, and the powder mixing efficiency of caking reduces; When hard ball 8 quantity are too much, account for inner core 2 volumes one half like hard ball 8, powder mixes difficulty, and discharging is also very difficult.Therefore, general quantity with hard ball 8 is controlled at and accounts for 5%～30% of inner core 2 volumes, and wherein optimum ratio is 10%～20%.

After powder mixes completion, need be from discharging in the inner core 2.At this moment, rotation urceolus 1 will be imported and exported 4 and rotate to extreme lower position, position promptly shown in Figure 2.Open and import and export 4, because the appearance and size of grid 9 is bigger than import and export 4, grid 9 can't break away from inner core 2.Grid 9 also stops the disengaging of hard ball 8 simultaneously.Suitably rock grid 9, the powder that mixes like this can leak down from importing and exporting 4, realizes discharging.

When inner core 2 or hard ball 8 serious wear need be changed, open the flange 3 that is arranged on urceolus 1 one sides, can directly take out inner core 2, and then change.
