Description
Technical field
The utility model relates to a kind of electronic scales, relates in particular to a kind of large-tonnage feed bin formula material level electronic scale.
Background technology
The iron and steel metallurgy enterprise of China, particularly large-scale steel plant have all taked superseded small furnace, primary converter, the conversion of newly-built large blast furnace and converter, the scale effect can reach energy-saving and emission-reduction, enhances productivity, and promotes the purpose of product quality.Current newly-built blast furnace is all at 2000m
3More than, supporting with it raw material storage, batching feed bin all maximize.The large-tonnage feed bin that in chemical industry, food and thermal power generation industry, needs raw material storage, batching equally.Along with the raising of enterprise to product quality, consumption of raw materials, cost management, measuring requirement to this large-tonnage feed bin is more and more higher, we are not only the height that will understand material level in the feed bin, also will finish the batching of material according to manufacturing technique requirent, this just needs a kind of device that can accurately measure weight of material in the feed bin.
In the past the large-tonnage feed bin was only carried out the online detection of material level in the feed bin, so very low to Testing requirement, whether people can overflow when feeding in raw material in feed bin as long as understand the height of material level in the feed bin, whether material is empty in the feed bin, whether needs to replenish information such as material.The most frequently used material level detection mode has ultrasound wave material level measuring method and radar type level gauging mode, and the principle of work and the mounting means of these two kinds of measuring methods are basic identical, and their principal feature is as follows:
The material level measuring method of these two kinds of metering systems is to be issued to the height that the time of returning draws material in the feed bin by measuring ultrasound wave or radar wave, thereby determines the height of material level.As calculating the weight of measuring material, then come calculated weight by volume and proportion.The measuring error of material level is very big, and measured material level is uneven by material and the influence of angle of rest (repose), is difficult to record correct material level, and the volume that therefore calculates gained thus is also incorrect, influenced by material moisture, granularity etc., and last gained weight error will be bigger.The installation site of ultrasonic material level detection unit must be at the top of feed bin, and installation, difficult in maintenance adds the charging aperture that feeding bin top is material, for charging aperture design has increased difficulty like this.Therefore these measuring methods can only detect the material level situation in the feed bin, can not be according to carrying out Charge Mixture Control with the measurement data.
Summary of the invention
The purpose of this utility model is: a kind of dependable performance is provided, and the accuracy of detection height can satisfy and measure the bin-level situation and control the large tonnage material level electronic scale that the batching operation requires.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of large tonnage material level electronic scale has the barrel storehouse, on same surface level more than the center of gravity of barrel storehouse, be provided with four or more equally distributed support pad seat, be separately installed with LOAD CELLS below each support pad seat, described LOAD CELLS is installed on the pedestal, and base height is higher than distance between barrel storehouse support pad seat and the discharging opening; There is sphere the upper surface of described LOAD CELLS, and the center of described sphere and the center of LOAD CELLS are same center.Form electronic scales with the LOAD CELLS more than 4 or 4, can alleviate the local pressure of feed bin bases such as floors.
Technique scheme can also be further perfect,
As preferably, described LOAD CELLS is the LOAD CELLS of pole structure.
As preferably, fixedlying connected with pedestal below by lower platen of described LOAD CELLS joined by top board and support pad seat above.
As preferably, it is the pressure head of spill sphere that the lower end is arranged between described LOAD CELLS and the top board, and the spherical diameter of pressure head is greater than the spherical diameter of sensor upper surface, and described pressure head is connected with top board.Pressure head is a concave spherical surface, just in time be buckled on the upper end sphere of LOAD CELLS, and certain small rocking arranged, when guaranteeing that outside multiple factor is exerted oneself slightly deflection, small rocking can take place by outer forced direction in sensor on sphere, make the sphere summit center line of alignment sensor all the time.
As preferably, be provided with the adjustment pad between described support pad seat and the top board, adjust the setting height(from bottom) of each sensor, make it after the installation on same surface level.
Therefore, the beneficial effects of the utility model are: adopt gravimetric method to measure bin-level situation and the operation of control batching, have simple in structure, easy for installation, maintenance is convenient, weighing precision height, long service life, and have the fabulous ratio of performance to price.

Accompanying drawing 2 is storehouse material vertical views of Fig. 1;
Accompanying drawing 3 is that LOAD CELLS is installed front view;
Accompanying drawing 4 is pressing plate planimetric maps.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Material level electronic scale scale structure as shown in Figure 1 and Figure 2, barrel storehouse 3 directly is shelved on the LOAD CELLS 1 by loading support pad seat 5, support pad seat 5 status requirements are chosen relative higher position, in barrel storehouse center of gravity with the upper part.Because the specification of feed bin is bigger, the utility model adopts 4 important actor formula LOAD CELLS to form electronic scales, alleviates the local pressure of feed bin to the basis.Among the figure, 4 is discharge mechanism, and 2 is pedestal.
LOAD CELLS installation diagram as shown in Figure 3, Figure 4, LOAD CELLS 1 upper end is a sphere 11, link to each other with pressure head 7, be a concave spherical surface below the pressure head, spherical radius is greater than the sphere of sensor 1 upper end, and the two just in time is buckled together, and certain small rocking arranged, when guaranteeing that outside multiple factor is exerted oneself slightly deflection, small rocking can take place by outer forced direction in sensor 1 on sphere, make the sphere summit center line of alignment sensor all the time.Upper and lower pressing plate 8,6 links to each other with pedestal 2 with scale body 1 respectively, and the adjustment pad of placing on the top board 8 of loading 9 is adjusted the setting height(from bottom) of each sensor, makes it after the installation on same surface level.
The utility model is applicable to the electronic scales installation of large-sized silos such as metallurgy, chemical industry, food.
