Abstract

The utility model provides a horizontal type drum mixing apparatus. The utility model is characterized in that the combination of a gravity type mixing and a forced action type mixing is used. The utility model has the advantages of simple structure, low energy consumption, small wear, short mixing time, convenient use and maintenance. The utility model is suitable for mixing the normal concrete grout with large water content for construction as well as is suitable for mixing the dry concrete grout with low water content for paving and other lightweight aggregate wet grouts.

Description

Combined mixer

The utility model relates to a kind of horizontal drum mixing plant, and particularly a kind of gravity type stirring and forced action type of adopting stirs the new composite mixing plant that combines.Be applicable to the stirring dry concrete, also be applicable to the stirring normal concrete.

Concrete batch plant in the prior art has two types, and promptly gravity type and forced action type are two kinds.Having formed the series of products typing produces in batches.For example, gravity type has JZ350 type mixer, and forced action type has JQ-250 type mixer.The blade that the gravity type concrete mixer is welded on the rotary barrel cavity wall when utilizing the rotation of its cylindrical shell takes material to eminence from lower, and the material lower that falls back voluntarily rolls up and down, constantly circulation, realize the purpose of mixing material, its shortcoming is that the whipping process time is long, and efficient is low.Forced concrete mixer is the blade rotation that utilizes on the shaft, and pressing materials stirs up and down, realizes evenly mixing, and its shortcoming is that power consumption is big, and wear liner is big, and difficulty of processing is big, and consumable material is many.

Task of the present utility model is will provide a kind of to include the forced stirrer structure and the new composite mixing plant of the rabbling mechanism organic composition that falls certainly, it integrates the advantage of traditional mixer, can either stir the big normal concrete slurry of rarer water content for building, have simple in structurely simultaneously, power consumption is few, and it is little to wear and tear, mixing time is short, be easy to make, material consumption is few, uses advantages such as easy to maintenance.

The utility model is finished as follows, on the traction base cylinder, drive unit, charge mechanism etc. is housed.When being driven cylindrical shell and rotated by drive unit, blade takes the lower material to certain eminence, the material branch lower that is scattered back then, and this process repeatedly circulates, and material is mixed thoroughly.In order to improve mixing effect, mandatory rabbling mechanism is installed on the cylindrical shell rotation, this mandatory rabbling mechanism mainly forces stirring vane, axle and gear mechanism etc. to be formed by 4～10 groups, and axle is connected with the traction base, does not rotate.Stirring vane can relatively rotate around axle, forces stirring vane that a pair of blade is arranged for every group, forces stirring vane faster slightly than the blade rotational speed of cylinder, is connected with gear with the axle sleeve of forcing stirring vane to connect firmly.The gear that connects firmly with cylinder passes to pressure stirring vane by one group of gear drive with rotating speed with velocity of rotation.Because force fast 1～4 times of stirring vane rotating ratio drum rotation speed, the coalescent material of part is broken up, and has changed the direction of motion and the movement velocity of material simultaneously, make interior material of identical time by repeated segmentation, obtain bigger agitation energy.The material of being broken up is pushed open to both sides, has played the mixing effect of forced action type.Because the pressure stirring vane on the axle does not contact with cylindrical shell, therefore, it is little that it has a power of agitator, the advantage that wear liner is little.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is vertical cross-sectional schematic of the present utility model.

Fig. 2 is that the K of Fig. 1 is to cross-sectional schematic.

On traction base ［ 1 ］, be equiped with cylinder ［ 10 ］, drive unit ［ 2 ］, charge mechanism ［ 8 ］ etc., its intermediate roll ［ 10 ］ inwall welding fixed blade ［ 9 ］ several, on the axial location of cylinder ［ 10 ］, be equiped with the forced stirrer structure, this forced stirrer structure is made up of axle ［ 7 ］, axle sleeve ［ 11 ］, pressure stirring vane ［ 3 ］, gear mechanism, bearing etc.One end of axle ［ 7 ］ connects firmly by fixing handle and traction base ［ 1 ］, and the other end of axle is bearing on the cylinder by bearing.In the gear mechanism, gear ［ 4 ］ and gear ［ 12 ］ engagement, gear ［ 13 ］ and gear ［ 5 ］ engagement, gear ［ 15 ］ and gear ［ 6 ］ engagement, gear ［ 12 ］ connects firmly with gear ［ 15 ］, and gear ［ 6 ］ connects firmly with cylinder ［ 10 ］, gear ［ 4 ］ connects firmly with axle sleeve ［ 11 ］, gear shaft ［ 14 ］ and cylinder ［ 10 ］ connect firmly, and force stirring vane ［ 3 ］ to have 8 groups and connect firmly with axle sleeve ［ 11 ］, force stirring vane ［ 3 ］ that 1 pair of blade is arranged for every group.During work, drive unit ［ 2 ］ head roll ［ 10 ］ rotates, cylinder ［ 10 ］ rotates by gear ［ 6 ］ driven gear ［ 15 ］, gear ［ 15 ］ and gear ［ 12 ］ rotation driven gear ［ 4 ］ rotation synchronously, force stirring vane ［ 3 ］ to rotate thereby make, meanwhile, gear shaft ［ 14 ］ and gear ［ 13 ］ are also revolving round the sun around gear ［ 5 ］.Because the gearratio of gear mechanism is 1:2.5, so the rotating speed of pressure stirring vane ［ 3 ］ and the rotating speed of cylinder ［ 10 ］ are inequality, stirring vane ［ 3 ］ rotating ratio cylinder is walked around fast fast 2.5 times, when cylinder ［ 10 ］ rotates, when fixed blade ［ 9 ］ takes material eminence to and falls again the stirring vane ［ 3 ］ through high speed rotating clash into, can make the quick mixing of material, raise the efficiency.
