Description

The vertical and high-speed mixer

The utility model relates to a kind of mixer, particularly relates to a kind of mixer that geotechnical engineering construction stirs system cement mortar or cement mortar that is used for.

The mixer specifications and models of mortar of being used to mix cement in geotechnical engineering construction are a lot, can be divided into vertical and horizontal two kinds substantially, and are maximum with the low-speed mixer.Also there is homogenizer to come out in recent years.But because sealing is unfavorable, cement that abrasiveness is extremely strong and sand grains very easily enter between the metal parts of at a high speed rotation, thus cause the equipment failure rate height, damage fast, the slurries leakage is serious.Moreover, be to join one barrel to stir one barrel when mixer is worked generally speaking, the numerous and diverse efficient of operation is low.And whole matching is also poor.

The purpose of this utility model is to provide a kind of seal isolation strong, cement mortar can't enter among the metal parts of rotation at a high speed, can effectively avoid or reduce equipment failure rate, spoilage and slurries leakage, increase work efficiency and service life of equipment and the stronger vertical and high-speed mixer of matching.

The technical solution of the utility model is as described below: this utility model comprises base, agitator tank, stirs cover plate, belt gear, feed hopper, main shaft, bearing sleeve, baffle, connecting key, blade, voltage-stabiliser tube, sealing ring and bolt, and this machine is to stir cover plate and agitator tank is divided into agitator tank and following agitator tank two parts by setting in agitator tank.Prolong pipe on main shaft outer setting bearing sleeve in last agitator tank and the main shaft, on prolong the pipe top and establish the labyrinth sealing isolator, the shear agitation device that is made of many groups of making beating bars and fixed stop pulpboards is established in the bottom.Last agitator tank also is fixed with feed hopper and overflow pipe.The strong mixer that the centrifuge blade that setting is connected with spindle nose in following agitator tank constitutes combines formation.

The utility model is owing to taked said structure, especially on main shaft peripheral hardware bearing sleeve and main shaft, prolong the bilayer sleeve of pipe composition and the labyrinth sealing spacer structures at top, add the shear agitation device, the combination of strong mixer, make this utility model have extremely strong sealing, isolation performance, can effectively avoiding by force, mill property cement mortar enters the rotation pair of friction components, thereby wearing and tearing have been reduced, improved the reliability of work, reduced the generation of fault, prolonged the service life of equipment, and it is novel unique that this utility model also has design concept, complete machine is comprehensive, segmentation is from top to bottom stirred, continuous high speed slurrying, constant product quality, high efficiency, advantage such as easy to use.

Below in conjunction with accompanying drawing the technical solution of the utility model is described in further details:

Fig. 1 is the overall structure schematic diagram of vertical and high-speed mixer.

By vertical and high-speed mixer shown in Figure 1 is a kind of novel mixing plant of developing on the prior art basis.This motor spindle is a base 1, and the slurry bucket is that the following cover plate 2 that stirs that agitator tank is established the hole by a center is divided into agitator tank 3 and following agitator tank 4.Last agitator tank top is fixed with stirs cover plate 5, on to stir cover plate 5 tops are belt gears 6.Also be provided with feed hopper 7, voltage-stabiliser tube 23 and overflow pipe on the last agitator tank 3.Last agitator tank 3 central authorities are main shafts 8 that driven by transmission mechanism 6, prolong the bilayer sleeves that pipe 10 is formed on main shaft 8 overcoat bearing sleeves 9 and the main shaft.The overcoat of this bilayer sleeve prolong promptly pipe 10 outer tops be provided with on prolong the disc labyrinth that pipe 10 rotates and multilayer distributes and get rid of circle 11, get rid of circle 11 relative also interleaved bits with the labyrinth and install quiet circle 12, quiet circle 12 is through its outside set labyrinth outer tube and spacer fixed interval.And get rid of circle with the labyrinth and 11 together constitute labyrinth sealing isolator 15.Prolong the even three groups of making beating bars 16 that constitute with its one that are furnished with from bottom to top in pipe 10 bottom on the main shaft, 60 ° each other of adjacent arbitrarily two making beating bars 16, three groups of making beating bars 16 are divided angle of circumference equally.And promptly go up on agitator tank 3 sidewalls in the interval of making beating bar 16 that fixed stop pulpboard 17 and making beating bar 16 are common to constitute shear agitation devices 13.It establishes main shaft lower outer pipe 18 in agitator tank (claiming to stir by force case again) 4 down, is connected and fixed through connecting key 19 and main shaft 8 ends.Main shaft lower outer pipe 18 is sealed by sealing ring, bolting and outer end are overlapped the centrifuge blade 21 of a main shaft lower pipe connection 20 and bilateral symmetry setting and are formed strong mixer 14, and following agitator tank 4 chews 22 by the whitewashing that bottom one side also is provided with discharging opening and pulp elbow composition.

During work, being stirred thing (as cement, sandstone, water etc.) adds from upper feed hopper 7, prolong pipe 10 rotation at a high speed on main shaft at last agitator tank 3 internal upper parts, naturally fall after the repeatedly dispersion of the shear agitation device 13 that many group making beating bars 16 and baffle 17 are formed is sheared, in the agitator tank 4, carry out brute force by strong mixer 14 again and stir under flowing into from the centre bore that stirs cover plate 2 down then.The linear velocity of the centrifuge blade 21 of strong mixer 14 is that 13m/s makes and is stirred thing and all disperses, under the centrifugal action of (this moment, product quality was presented slightly excellent state down) and the big pressure in following agitator tank 4 and centrifuge blade 21 high speed rotation generations, make slurries chew 22 ejections automatically from whitewashing.As long as continuously drop into from feed hopper 7, just can realize all processes of continuous slurrying, pulp being stirred thing.Comparable other vertical mixer of this mechanism slurry efficient is enhanced about more than once.
