A concrete mixer truck includes: a driving device that drives a mixer drum to rotate; a pressure sensor that detects a pressure of the working fluid in the driving device; a material introduction determination unit that determines whether or not a material for generating the mixed concrete has been introduced into the mixer drum; a pressure determination unit that determines whether or not the pressure of the working fluid detected by the pressure sensor has fallen to a set pressure set in advance in accordance with a carrying amount and a fluidity of the mixed concrete after the introduction of the materials for the mixed concrete into the mixer drum; and a notification device that notifies an operator that the pressure of the working fluid in the driving device has fallen to the set pressure on the basis of the determination made by the pressure determination unit.

摘要:
A water supply system (1) having at least one pressure pump (9), at least one pressure tank (3) and a plurality of water tanks (2) and (36). A submersible pump (37) is connected to a well (38) and a main water tank (36), which is connected to the other water tanks (2) via hoses (4), is connected to the pressure pump (9). The pressure pump (9), in turn, is connected to the pressure tank (3). Finally, the pressure tank (3) is connected to a plurality of water supply pipes (5) which supply water to varying areas of a plant. The main water tank (36) contains a plurality of float switches (28) at varying levels so as to indicate when the water supply needs to be activated, when the water tanks (2) and (36) are getting low and when the water tanks (2) and (36) are extremely low and the pressure pump (9) needs to be deactivated. When the pressure pump (9) is deactivated, the water is pumped from a submersible pump (37) to fill the water tanks (2) and (36). An electrical housing station (6) is used in conjunction with the water supply system (1) so as to supply power to the pressure pump (9) and includes a means for indicating varying water levels in the water tanks (2) and (36).
摘要:
A system for calculating and reporting slump in a delivery vehicle having a mixing drum (14) and hydraulic drive (16) for rotating the mixing drum, including a rotational sensor (20) configured to sense a rotational speed of the mixing drum, a hydraulic sensor (22) coupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, and a communications port (26) configured to communicate a slump calculation to a status system (28) commonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum.
摘要:
The invention relates to a process for the granulation of sludge- and optionally dust-form material, in which the material to be granulated is mixed with hydratable or hydraulically settable solids and water, which solids react exothermically with water and act as binder in the mixture, where the solids are allowed to hydrate or set fully or partly, and where the mixture containing the fully or partly hydrated or set solids is shaped into granules, where the solids and, if desired, dust-form materials to be granulated are wetted or moistened with water, and subsequently and/or at essentially the same time the solids are mixed with the material to be granulated. The invention also relates to an apparatus for carrying out the process.
摘要:
A system for transferring coloring agents for concrete to a ready mix truck or the like, includes a tank for receiving coloring agents. The tank includes lines for supplying it with water and a pump for transferring the coloring agents to the ready mix truck through a discharge line.
摘要:
A portable mixing/delivery apparatus mixes dry pre-blended materials, such as homogeneous cementitious combinations of dry sand, cement, lime, color pigments, etc., packaged in large bulk bags for use at a remote construction site. The bulk bag is lifted by a removable rack having plural lift eyes and the combination is positioned over a height adjustable frame. The granular material is then discharged into a continuous mixer having a dynamic input mixing stage, an output dry-to-wet mixing stage, and a transition stage therebetween. The enter assembly (bulk bag, frame and continuous mixer) is portable and can be lifted such as by a forklift to the height of a masonry scaffold for dispensing the mixed, wet granular material directly to the point of use. The apparatus allows the continuous mixer and its discharge tube to rotate to facilitate dispensing of the material directly to the point of use.
摘要:
A portable hand-held concrete, mortar and gypsum mixer comprises a small gasoline powered implement having a drive shaft extending generally downward from the handles to a gear box. A transverse shaft driven by the drive shaft extends to either side of the gear box. Mounted on the transverse shaft are a plurality of blades shaped to thoroughly agitate and mix a combination of water and the ingredients for concrete, mortar, gypsum or similar heavy, hard to mix materials. Surrounding the blades are thin rings attached to the blades to form a round circumferential surface about the blades and thereby prevent the blades from directly contacting the mixing trough or other means of containing the mix. In the alternative, the plurality of blades may be shaped at their peripheries to form substantially continuous circular circumferences. Further improvements to the hand-held mixer comprise a positionable handle to easily control the mixer from the side, a flexible extension extending from the drag bar for more speed control by the user by manually changing the vertical orientation of the mixer handles, and openings through the mixing blades to more thoroughly mix the material by transverse movement of the material through the openings in the blades.
