Abstract

A premixed concrete double mixing device mainly adopting the following structure: a mixing machine with the production capacity being one half of that of the original mixing machine is arranged on the prior equipment only having a single mixing machine and is positioned above a main mixing machine; the utility model is provided with a main machine platform which is provided inside with an upper mixing machine, a lower mixing machine and a finished product storage hopper. Through separate measuring by single gauge and separate feeding by single feeding device of rough and fine aggregate materials and cementing materials, the utility model inputs sand into the upper mixing machine and completes premixing of the sand with cementing materials such as water, cement, hearthstone and fly ash inside the upper mixing machine; and then, rough aggregate materials such as stone are input into the lower (main) mixing machine to be mixed again with the premixed cementing materials so as to increase evenness and yield of concrete.

Description

The two mixing devices of ready-mixed concrete

The utility model relates to the two mixing devices of a kind of ready-mixed concrete.

See also shown in Figure 1, known ready-mix plant is with sand, stone, cement, hearthstone, material such as flying dust and additive is by accumulator tank A, F, G is through conveying equipment D, measuring equipment B, together drop in the single mixing machine behind the C and stir, because existing traditional type mixing plant all adopts single main frame E, the mode of (mixing machine) stirs, the discrepant phenomenon of mix finished product quality inhomogeneous and finished product all can be caused in the order and the position that feeds intake that cause raw material to drop into mixing machine, can not in a set time, be stirred to all raw materials in the ideal uniform scope, mixing speed is slow, whole cost is improved, in order to improve above-mentioned legacy equipment shortcoming, this creator is deeply studied, improve, and develop a kind of new concrete manufacturing installation.

Main purpose of the present utility model is to provide a kind of ready-mixed concrete two mixing devices, and it is divided into two sections mixs by mixing machine up and down, can make the ready-mixed concrete mix to uniform state.

Secondary objective of the present utility model is to provide a kind of ready-mixed concrete two mixing devices, can improve mix speed to reduce production costs.

Another purpose of the present utility model is to provide a kind of ready-mixed concrete two mixing devices, solve present plant equipment the problem that can't improve, and can reduce the cement and about 5% to 10% (because of the product occupation mode and the intensity change) of additive amount of same intensity concrete product, further reach and reduce cost the purpose of increase profit.

For achieving the above object, the utility model is achieved through the following technical solutions: the two mixing devices of a kind of ready-mixed concrete, it is characterized in that: its tool one main engine bed, be provided with a upper strata mixing machine, lower floor's mixing machine and a finished product storage bin hopper in this main engine bed, wherein this upper strata mixing machine is to stir cementing material and cement to set to drop into behind the duration of mixing again and be stored in finished product storage bin hopper wait shipment after lower floor's mixing machine and coarse aggregate and water stir once more in advance.

This cementing material be in sand, cement, flying dust and the hearthstone etc. several or all.

This coarse aggregate is a stone.

This cementing material is delivered to groove to be mixed via individual other meter and conveying device.

This conveying device is transported machine or gas transportation machine for the spiral shell of carrying cementing material,

Perhaps this conveying device is for carrying the conveyer belt of coarse aggregate.

This upper and lower mixing machine is that disc type mixing machine, horizontal single shaft mixing machine, horizontal twin shaft mixing machine and drum-shape mixing machine etc. are wherein a kind of.

By the two mixing devices of the utility model ready-mixed concrete, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, utilize the utility model to reduce cost, increase profit.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is known concrete agitator configuration schematic diagram;

Fig. 2 is the two mixing device configuration schematic diagram of the utility model ready-mixed concrete;

Fig. 3 is that aggregate of the present utility model storehouse and aggregate measuring equipment are faced, side view;

Fig. 4 is the facing of mix main engine bed, the side view of the pre-mixing equipment of the utility model;

Fig. 5 is a pre-mixing equipment top view of the present utility model (planar configuration).

At first, see also shown in Fig. 2,3, the two mixing devices of a kind of ready-mixed concrete, mainly be to be provided with aggregate storehouse 1, it separates with dividing plate, Yi Bian put stone, another side is then put sand, toward next be funnel-form, have an outlet to accept a

meter

2,3 individually, sand, stone are understood after having measured transport to the premixing place by the conveyer belt under it 4,5.

See also Fig. 2 again, 4 and shown in Figure 5, premixing place tool one main engine bed 100, mainframe 100 tops are installed with sand and treat hopper 10, cement batcher 12, flying dust meter 13, hearthstone meter 14 etc., its underlying is provided with a upper strata mixing machine 15, opening on it then is connected to conveying cement respectively, flying dust, the spiral shell fortune machine or the gas transportation machine 121 of hearthstone, not 131 (figure does not show), 141 and the openend of sand conveyer belt 4, the other end of these spiral shell fortune machines or gas transportation machine then bears individually and is stored in cement accumulator tank 6,7, the cement of hearthstone accumulator tank 8 and flying dust accumulator tank 9, hearthstone, flying dusts etc. are so that be delivered to cement batcher 12, flying dust meter 13, hearthstone meter 14 etc.Then, enter the upper strata mixing machine 15 that is positioned under it through cement, flying dust or the hearthstone etc. that measure simultaneously with sand stirs in setting-up time in advance, cementing material after the stirring then again with deposit in the position and treat to enter stone hopper 11 in down simultaneously at the stone on upper strata mixing machine 15 next doors mixing machine 16 stirs to get uniform ready-mixed concrete simultaneously with water, be stored in then on the finished product storing, wait for shipment.Upper and lower mixing machine 15,16 in the main engine bed 100 can be arranged in pairs or groups with the characteristic of production product category form, as: disc type mixing machine, horizontal single shaft mixing machine, horizontal twin shaft mixing machine and drum-shape mixing machine etc. are wherein a kind of.

The utility model takes sand, stone to measure respectively, carries respectively.Materials such as sand, water, cement, hearthstone and flying dust drop into upper strata mixing machine 15 and stir into sand mud (cementing material) in advance, drop into lower floor's mixing machine 16 again and stir once more with stone, additive.Since sand mud upper strata mixing machine 15 be stirred to a certain degree uniform state and because of sand mud in do not have coarse aggregate (stone).Sand, water, cement have more multilist area contact, thereby evenly mixer can heighten.And upper and lower two mixing machines will stir respectively, stirred 40 seconds with every mixing machine, so the product of each circulation all pass through and amount to 80 seconds mix, and the uniformity of product can reach stirring cmpletely; And the mixing machine 15,16 of upper and lower layer, working respectively is not subjected to influence each other, and each circulation time used is in 40 seconds, and each circulation time used is only in 40 seconds.As being example with the 3M3 mixing machine, 1 hourly average production capacity can reach 90 circulation 270M3 production capacities, and actual duration of mixing is set with proportioning and decided, and production capacity can be distinguished to some extent with the duration of mixing number.

The above is not to be used for the utility model is done any pro forma restriction, be with, all have following of identical creation spirit do any modification of relevant the utility model or change, all must be included in the category of the utility model intention protection.
