Detailed description of the invention
The utility model is for the abundant mixed problem of the liquid material comprising two or more component such as sticky material or easy layering material (such as coating, sizing material, paint etc.), particularly for the abundant mixed problem of the sticky material of layering easy between component, provide a kind of mixing device, it is for stirring the liquid material in the container of upper opening.
First see accompanying drawing 1-3, liquid material to be mixed is contained in the container 1 (such as expecting cylinder, barrel, material storing box etc.) of upper opening.Mixing device of the present utility model mainly comprises rabbling mechanism and driving mechanism.Wherein, as shown in Figure 1, described rabbling mechanism preferably includes bar portion 2 and is positioned at the batch mixing dish 3 of described bar portion 2 end, and described rabbling mechanism is installed with being suspended, can stretch into downwards in described container 1.Described rabbling mechanism can pump under the driving of described driving mechanism.At this, batch mixing dish 3 is preferably tabular component, and its upper and lower surface is preferably vertical with the described direction pumped, and thus when it moves up and down in the material that viscosity is higher, can form upper and lower stirring action to material.
When holding appropriate liquid material in container 1, by driving rabbling mechanism to pump, mixing device of the present utility model can carry out upper and lower automatic stirring to liquid material, thus can promote that material fully mixes, and avoids lamination.
When adopting the mode of stirring up and down to stir, when often not wishing that rabbling mechanism is up, going out liquid level, splashing in order to avoid cause when again declining and/or bringing bubble into.To this, preferably, mixing device of the present utility model also comprises relative to the hard-wired displacement transducer 4 of described rabbling mechanism, for the height detecting material liquid surface, institute's displacement sensors 4 is installed into has constant vertical distance (it is higher than batch mixing dish 3) between described batch mixing dish 3, and when described rabbling mechanism stretches in described container 1, institute's displacement sensors 4 is positioned at the opening range of described container 1 in the horizontal direction, namely, institute's displacement sensors 4 can be arranged in overthe openings or the opening (as long as being positioned at ullage) of described container 1.
By detecting liquid level in real time, easily can judge the difference in height of batch mixing dish 3 apart from liquid level, thus batch mixing dish 3 can be avoided in up process to go out liquid level.Such as, because the distance (can be described as the first distance) between displacement transducer and batch mixing dish is known and constant, this first distance deducts the distance of liquid level to displacement transducer, and the first difference obtained is the difference in height of batch mixing dish upper surface to liquid level.So, by setting safe minimum first difference (it corresponds to the maximum allowable range of liquid level to displacement transducer), under can ensureing that batch mixing dish is positioned at liquid level all the time.Also namely, once displacement transducer detects that the distance between liquid level to displacement transducer reaches aforementioned maximum allowable range, then the upstroke of rabbling mechanism can be stopped immediately.
On the other hand, when adopting the mode of stirring up and down to stir, often do not wish that rabbling mechanism touches container bottom, in order to avoid cause the damage of device yet.To this, those skilled in the art will find apparent that the mode arranging limit inferior switch is to prevent rabbling mechanism descending excessive, to ensure safety.When batch mixing dish 3 (is such as positioned at the lower limit position of setting in advance close to container bottom, also i.e. criticality safety position) time, the distance (can be described as second distance) between displacement transducer 4 and container bottom is also easily to know in advance and constant.This second distance deducts the distance of liquid level to displacement transducer, and the second difference obtained is actual liquid level.Visible, mixing device of the present utility model can also actual liquid level easily in measuring vessel.
Preferably, the displacement transducer 4 adopted in the utility model can be ultrasound displacement sensor or optical displacement sensor.Such as, when adopting ultrasound displacement sensor, it sends ultrasonic signal towards liquid level, and is received from the ultrasonic signal that liquid level reflects, thus can obtain the distance of liquid level to ultrasound displacement sensor easily.Alternatively, optical displacement sensor (such as utilizing laser, infrared light etc.) also can obtain the distance of liquid level to displacement transducer easily.
Preferably, as shown in Figure 1, for convenience of installation position, ground displacement sensor 4, mixing device of the present utility model comprises support 5, described support 5 pumps under the driving of described driving mechanism, and described rabbling mechanism and institute's displacement sensors 4 are installed on described support 5.Also namely, by arranging the support 5 that can pump, moving up and down and relative fixing between rabbling mechanism with displacement transducer of rabbling mechanism can be realized easily.It is contemplated that displacement transducer 4 also can be arranged on rabbling mechanism, such as, be arranged in bar portion 2 by means of changeover mechanism.
Automatic mixing machine structure of the present utility model, by reciprocally stirring up and down, can make the material component of easy layering fully mix, and reach the degree meeting commercial Application and require, thus the material mixed directly can enter subsequent handling, such as painting process etc.
But in order to improve automaticity and integrated level further, reduce the switching latency of inter process, mixing device of the present utility model preferably also comprises Chou Liao mechanism, thus after stirring or can directly take out material while stirring and carry out commercial Application.For this reason, the feeding mouth of described Chou Liao mechanism is preferably arranged in described batch mixing dish 3.
Such as, bar portion 2 can be arranged to hollow (such as pipe fitting), thus the pan feeding pipeline of Chou Liao mechanism (such as comprising pump and pipeline) can pass from the hollow part in bar portion 2, and such as exposing in the opening of middle part setting at batch mixing dish 3, thus when batch mixing dish 3 is positioned under liquid level, just can carry out taking out material operation.
On the other hand, when Chou Liao mechanism and rabbling mechanism are integrated in same device, can also prevent the material mixed from the unfavorable phenomenons such as layering when slower (such as due to materials process) occurring again in the process of materials.
In addition, due to self non rotating of the rabbling mechanism in mixing device of the present utility model, that is, it is fixed relative to support, this also make Chou Liao mechanism and being connected and installed between it simple especially.By contrast, if adopt rotary agitator mechanism, the installation of Ze Chouliao mechanism is obviously more complex.
