The upper part of the inner cylinder 26 is an open stainless steel cylinder, the outer wall of the upper part of the inner cylinder 26 is provided with an annular convex supporting platform, and an annular rubber ring 27 is arranged between the convex supporting platform and the outer cylinder; the outer cylinder is divided into a cylinder cover 28 and a cylinder body 29, the cylinder cover 28 is fixed on the top of the cylinder body 29 through threads, a supporting platform matched with a raised supporting platform of the inner cylinder 26 is arranged in the cylinder body 29, and a rubber ring 30 is arranged between the supporting platform on the outer cylinder and the inner cylinder 26; the cylinder 31 is arranged between the supporting platforms of the inner cylinder 26 and the outer cylinder, and the top of the cylinder 31 is provided with a pressure sensor 32 for detecting the weight change of the inner cylinder 26 and the loaded materials. A fiber filter screen I34 is arranged at the bottom between the outer barrel body 29 and the inner barrel 26, a soft rubber ball 35 is arranged in the conical opening of the outer barrel and used for controlling the material discharge of the inner barrel 26, and a flexible plastic strip 36 is arranged outside the conical opening of the outer barrel and used for preventing the reverse circulation of airflow.
As shown in figure 1, the number of the material weighing and feeding bins can be 3, the material weighing and feeding bins are arranged at the top of the atomization bin and are respectively a water reducing agent weighing and feeding bin 1, a cement weighing and feeding bin 2 and a micro powder weighing and feeding bin 3, and the material weighing and feeding bins are used for weighing and feeding dry materials. The liquid is weighed and is thrown the feed bin and can be 2 settings on the lateral wall on atomizing storehouse upper portion for the weighing of water is thrown in, and the water atomization discharge gate that the feed bin 5 was weighed to water stretches into in the storehouse from the lateral wall in atomizing storehouse.
The main material of the fiber filter screen I34 is cotton and hemp, and the fiber filter screen I is woven into a cloth shape with extremely fine gaps and is stacked into a certain thickness to play the roles of wall protection and dust prevention. On the one hand, when the inner barrel 26 ascends, aggregate can overflow into the cavity area between the inner barrel and the outer barrel, and on the other hand, the internal pressure of the machine is relatively stable, so that the phenomenon that the airflow circulates too fast to influence the quantitative feeding of the aggregate is avoided.
The stirring bin comprises a stirring helical blade 17 and a bottom bin gate 19, wherein the stirring helical blade 17 is transversely arranged in the stirring bin, the bottom bin gate 19 is divided into two halves which are respectively hinged to the bottoms of bin walls at two sides of the stirring bin, and the opening and the closing are realized through mechanical power.
The stirring helical blade 17 is driven to rotate by the motor 16, so that the mixed materials are stirred.
The mechanical arm 20 is fixed outside the bottom bin gate 19, and the mechanical arm 20 is driven to turn over by an alternating current servo motor 22 (model: 80 ST-H02430750W) to realize the opening and closing of the bottom bin gate 19.
And the wall of the atomization bin is also provided with an exhaust hole, and a fiber filter screen II 13 and a rubber plug array 14 are arranged at the exhaust hole.
The fiber filter web II 13 is made of the same material as the fiber filter web I34. The rubber array 14 is formed by staggered square rubber blocks, when the air pressure in the atomizing bin is too high, part of air can leak through gaps among the rubber blocks, and the internal pressure is kept stable.
If the internal pressure is too high, the aggregate is difficult to fall through the dead weight, the weight counting element cannot identify the weight reduction of the aggregate, the operation is continuously kept, and the equipment is damaged; particularly, the internal pressure is too high to generate upward thrust, so that the aggregate is easy to eject out of the outer bin and cannot fall freely, and the aggregate is easy to spray outwards in serious cases; therefore, the pressure relief treatment is very important, and the fiber filter screen II 13 and the rubber array 14 arranged in the chamber can keep the relative balance of the internal pressure and the external pressure.
The use method of the equipment for ultrafine powder, cement, water reducing agent and water atomization for concrete stirring comprises the following specific steps:
the required materials are loaded into corresponding material weighing and feeding bins in a classified manner, according to the specified consumption proportion of the materials, after the feeding amount is input, the equipment is started, the air cylinder 31 is lifted upwards, the bottom of the inner barrel 26 leaves the soft rubber ball 35, the materials descend, and when the materials pass through a discharge hole, the falling materials are sprayed out by the air blower 4, so that the powder atomization effect is generated;
liquid materials in the liquid weighing and feeding bin pass through the atomizing chamber 6 and then are atomized and sprayed, the atomized materials enter the atomizing chamber to be mixed with dry powder materials, and after the materials are mixed and atomized, the materials fall to the stirring chamber and are stirred and mixed by the stirring helical blades 17;
an atomization chamber: the atomizer is arranged in the atomizing chamber, and an LM-40 plunger pump is adopted to atomize the liquid to generate fog-like water drops which are sprayed into the atomizing bin through a pipeline.
Because the air blower 4 is always in a working state, the pressure in the bin can be increased, the residual pressure can leak through the fiber filter screen II 13 at the moment, after filtration, the materials are left in the bin, the redundant air pressure is discharged along with gaps among the rubber plug arrays 14, the flexible plastic strip 36 is influenced by the reversed air flow, can be adsorbed on the soft rubber ball 35, the air flow is prevented from going backwards, and the flexible plastic strip 36 only can allow the materials to fall under the action of the gravity of the materials;
when the pressure sensor 32 detects that the mass difference value reaches a set value, the air cylinder 31 retracts immediately, the bottom of the inner cylinder 26 is plugged by the soft rubber ball 35, the material stops being supplied, the flexible plastic strip 36 also can be influenced by the air flow, upwards contacts with the soft rubber ball 35 to plug the discharge hole immediately, after stirring is finished, the air blower 4 and the atomizing chamber 6 are stopped, the bin is opened for discharging, the bottom bin gate 19 is opened, the mixed material is removed, and the bottom bin gate 19 is closed after cleaning.
