Description
Technical field
The utility model relates to static grain-to-grain pressure fields of measurement, relates in particular to a kind of static grain-to-grain pressure measurement mechanism.
Background technology
1980, Reimbert proposed a kind of for analyzing the method for mechanical behavior of silo, in eccentric and dynamic pressure situation when eccentric discharging not, and drew by experiment superpressure coefficient comprising silo.He thinks that superpressure coefficient depends primarily on the shape of the characteristic of storing, discharge port and the ratio of height to diameter of size and silo.Therefore and be not suitable for other storing but Reimbert equation is just based on semiempirical method, and experiment material used is barley.The utility model provides a kind of static grain-to-grain pressure measurement mechanism, and the pressure that can produce silo various static particles carries out high-acruracy survey.
Utility model content
In view of this, the utility model provides a kind of static grain-to-grain pressure measurement mechanism, comprise the first side lever, the second side lever, bottomless glass infuser, multiple sidepiece pressure transducer, the base pressure sensor in nothing top, on described glass infuser, offer multiple through holes, in each through hole, be placed with sidewall piston, described sidewall piston is connected on sidepiece pressure transducer; The bottom of described glass infuser is placed with bottom piston, and described bottom piston is connected on base pressure sensor; Described multiple sidepiece pressure transducer is arranged on the first side lever; Described the second side lever is for supporting glass infuser; The first side lever and the second side lever are arranged on the both sides of glass infuser.

Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or scheme of the prior art, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the static grain-to-grain pressure measurement mechanism that Fig. 1 provides for the utility model one embodiment.
Embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is carried out to clear, complete description, obviously, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
The structural representation of the static grain-to-grain pressure measurement mechanism that Fig. 1 provides for the utility model one embodiment, as shown in Figure 1, the static grain-to-grain pressure measurement mechanism of the present embodiment, comprise the first side lever 1, the second side lever 2, bottomless glass infuser 3, multiple sidepiece pressure transducer 4, the base pressure sensor 7 in nothing top, on described glass infuser 3, offer multiple through holes, in each through hole, be placed with sidewall piston 5, described sidewall piston 5 is connected on sidepiece pressure transducer 4; The bottom of described glass infuser 3 is placed with bottom piston 6, and described bottom piston 6 is connected on base pressure sensor 7; Described multiple sidepiece pressure transducer 4 is arranged on the first side lever 1; Described the second side lever 2 is for supporting glass infuser 3; The first side lever 1 and the second side lever 2 are arranged on the both sides of glass infuser 3.The range of described sidepiece pressure transducer 4 is 5kg, and precision is 0.1kg.The range of described base pressure sensor 7 is 150kg, and precision is 0.1kg.
The static grain-to-grain pressure measurement mechanism of the present embodiment, utilizes the numerical value of the lateral wall pressure of pressure transducer real time record particle in relaxation process, and the data after relaxation are averaged, and has formed a whole set of and has measured the method for ball bed to chamber wall lateral wall pressure.As shown in Figure 1, dig the hole of multiple differing heights at glass infuser sidewall, piston is connected with sensor, the variation in experimentation by collector real time record glass infuser lateral wall pressure and base pressure.First, side lever is adjusted, then the base pressure sensor that is connected with bottom piston is put on ground, in order to ensure that bottom piston is perpendicular to glass barrel, chassis can be set on the ground, adjust chassis screw, base pressure sensor is positioned on chassis, and make as far as possible base pressure sensor and chassis keep vertical; Then glass infuser is placed on chassis, makes bottom piston be positioned at glass infuser; After adjusting glass infuser, sidewall piston is connected with side sensor, then sensor is fixed on the first side lever, next adjust the position of side sensor on the first side lever, sidewall piston is just in time placed in the hole of glass infuser sidewall.
Before glass infuser filler particles, the raw data F1 of each sensor when record is unloaded; Calculate the height of particle post by the proportionate relationship of glass infuser diameter and actual silo diameter, by the highly-filled good particle calculating, after filling, the pressure data of sensor record each point, be designated as F2, the stressed F=F2-F1 of each point, measures the diameter of piston, calculate the area S of piston, obtain the pressure of each point: P=F/S.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement, and these amendments or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of the utility model.
