Technical field
The present invention relates to constructional engineering machinery field, especially, is a kind of concrete mixer.
Background technology
In concrete batch plant, it is the most simply self-dumping mixer, its primary structure as shown in Figure 1, comprise pedestal 1, pedestal 1 props up rotating cylinder 2 by support wheel 10, and rotating cylinder 2 periphery has ring gear, and this ring gear is engaged in driven wheel 30, the driving mechanism 3 that this driven wheel 30 is fixed on pedestal 1 driven, and makes rotating cylinder 2 around the continuous slow circumvolve of own axes; Rotating cylinder 2 inwall has the radial plate 21 extended to axis radial direction, concrete 4 is first in the bottom of rotating cylinder 2, along with the rotation of rotating cylinder 2, held up by radial plate 21, when rotating to state shown in Fig. 1, concrete 4 falls to rotating cylinder diapire under gravity again, and then held up, so circulate, in the process that concrete drops, make self to elongate as water column because concrete each several part successively falls, concrete relies on elongation effect during this whereabouts that each several part is mixed.Because this kind of self-dumping mixer is without action of forced stirring mechanism, therefore, required power is less, and hardware cost is lower, and more weak to power system requirements.
But because concrete mobility is far weaker than water body, in dropping process, the Blending Efficiency of Blending of its inside is in fact very poor; Although this causes this kind of mixer power less, mixing cycle is extremely very long, needs concrete to hold up heap of times, and falls, and just can obtain good Blending Efficiency of Blending, thus makes total energy consumption larger; In addition, for the concrete that some plasticity are poor, be almost difficult to pull into strip, adopt this kind of self-dumping mixer substantially cannot realize stirring.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of energy-saving concrete mixer, this mixer, on the basis that gravity type mixes, can significantly improve concrete Blending Efficiency of Blending, and save energy.
The technical scheme that actualizing technology object of the present invention adopts is: this energy-saving concrete mixer comprises pedestal, and described pedestal supports rotating cylinder by support wheel, and described rotating cylinder periphery has ring gear, and described ring gear is engaged in the driven wheel on driving mechanism; Described rotating cylinder inside has a cartridge filter, and the barrel of described cartridge filter is surrounded by web plate; There is between described cartridge filter and the barrel of rotating cylinder radial fixing radial dividing plate.
As preferably, described driving mechanism is motor.
As preferably, described radial dividing plate is fixed on the inwall of described rotating cylinder, and during the dead in line of the axis of described cartridge filter and rotating cylinder, each described free end of radial dividing plate has equal radial distance with the barrel of cartridge filter; And described cartridge filter is unfettered in radial directions, can freely-movable; Further, the mesh diameter of half perisporium of described cartridge filter is less than the mesh diameter of second half perisporium, and namely the mesh knitted density of half perisporium is less than the mesh knitted density of second half perisporium.
Beneficial effect of the present invention is: this energy-saving concrete mixer operationally, the concrete be in bottom rotating cylinder is held up by radial dividing plate along with the rotation of rotating cylinder, after rising to the top of rotating cylinder, fall under gravity to cartridge filter, because cartridge filter is surrounded by web plate, therefore, concrete will pass twice through the perisporium of cartridge filter, in the process, the steel wire being woven into mesh evenly and thick and fast cuts through inside concrete everywhere, thus forms good Blending Efficiency of Blending to concrete; Due to the mesh of cartridge filter to concrete cutting power still from concrete self power, therefore the power of system is substantially identical with common self-dumping mixer, and in the process often rotated a circle at rotating cylinder, concrete Blending Efficiency of Blending is largely increased, therefore, required mixing time will significantly shorten, thus save large energy.
Accompanying drawing explanation
Fig. 1 is that the end of common energy-saving concrete mixer is to structural representation.
Fig. 2 is that the end of this energy-saving concrete mixer embodiment is to structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in Figure 2, this energy-saving concrete mixer comprises pedestal 1, and described pedestal 1 supports rotating cylinder 2 by support wheel 10, and described rotating cylinder 2 periphery has ring gear (not shown), and described ring gear is engaged in the driven wheel 30 on driving mechanism 3; Described rotating cylinder inside has a cartridge filter 5, and the barrel of described cartridge filter 5 is surrounded by web plate; There is between described cartridge filter 5 and the barrel of rotating cylinder 2 radial fixing radial dividing plate 21.
In the present embodiment, described driving mechanism is motor.Described radial dividing plate 21 is fixed on the inwall of rotating cylinder 2; And during the dead in line of the axis of described cartridge filter 5 and rotating cylinder 2, the free end of each described radial dividing plate 21 has equal radial distance with the barrel of cartridge filter 5; And described cartridge filter 5 is unfettered in radial directions, can freely-movable.According to the program, in the rolling process of rotating cylinder 2, when the lower peripheral wall of cartridge filter 5 contacts each radial dividing plate 21 successively, generation is beated, as in Fig. 2, originally a place of cartridge filter 5 and radial dividing plate, b place contact, after rotating cylinder 2 turns over certain angle counterclockwise, cartridge filter 5 will drop downwards, contacts with the b place of radial dividing plate, c place; This of cartridge filter 5 drops and again by the process that radial dividing plate 21 props up, makes cartridge filter 5 produce strong vibration, now, effectively can promote that the concrete 4 be attached on cartridge filter perisporium passes its mesh.
In addition, then make the mesh diameter of half perisporium of described cartridge filter 5 be less than the mesh diameter of second half perisporium, namely the mesh knitted density of half perisporium is less than the mesh knitted density of second half perisporium, according to this scheme, because mesh diameter is less, namely the mass density of half perisporium that mesh density is larger is larger, thus make this half perisporium under gravity, remain at below, and larger half perisporium of mesh remains at top, thus make concrete 4 in the process of passing this cartridge filter 5, automatically coarse filtration and fine filtering two processes are achieved, to improve in process that rotating cylinder 5 rotates a circle, through the concrete total amount of cartridge filter 5 (because concrete 4 kinetic energy of top is less, ability through mesh is more weak, make the mesh of top larger, that can improve concrete 4 passes rate, when concrete arrives below, there is larger kinetic energy, therefore be able to a large amount of through thinner mesh), therefore, this kind of uneven mesh distribution can improve concrete overall blending efficiency.
Above-mentioned energy-saving concrete mixer operationally, the concrete be in bottom rotating cylinder 2 is held up by radial dividing plate 21 along with the rotation of rotating cylinder 2, after rising to the top of rotating cylinder 2, fall to cartridge filter 5 under gravity, because cartridge filter 5 is surrounded by web plate, therefore, concrete 4 will pass twice through the perisporium of cartridge filter 5, in the process, the steel wire being woven into mesh evenly and thick and fast cuts through concrete 4 various places inside, thus forms good Blending Efficiency of Blending to concrete; Due to the mesh of cartridge filter 5 to the cutting power of concrete 4 still from the self power of concrete 4, therefore the power of system is substantially identical with common self-dumping mixer, and in the process often rotated a circle at rotating cylinder 2, concrete Blending Efficiency of Blending is largely increased, therefore, required mixing time will significantly shorten, thus save large energy.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
