Abstract
The utility model relates to a measuring system, and particularly relates to a high-precision charging system. The high-precision charging system which comprises a header tank storage tank and a charging pump, and further comprises a measuring tank and a weighing module fixedly arranged at the bottom of the measuring tank, wherein a feeding hole of the measuring tank is communicated with the header tank storage tank through a material pipe with a control valve, a discharging hole of the measuring tank is communicated with the charging pump through a material pipe with a control valve, and the charging pump, the weighing module and the control valve are connected with a control module through data lines. The high-precision charging system is high in measuring precision, and accurate in raw material adding amount so that the quality of products in chemical industry is ensured, and is high in charging speed so that the work efficiency is increased.
Description
Technical field
The utility model relates to a kind of metering system, especially relates to a kind of high accuracy charging system.
Background technology
the Chemical Manufacture industry needs a large amount of raw materials, raw material generally is stored in high-level storage groove, then by charge pump, quantitative past reactor feeds in raw material, present metering method is, in the high-level storage groove bottom, one measurement instrument is set, in the reinforced process of charge pump by the numerical value change of paying close attention to measurement instrument determine feeding quantity the number, because the tonnage of high-level storage groove is all larger, be generally more than 25 tons, the range of the measurement instrument that high-level storage groove is joined is very large, the less raw material for consumption, the measurement instrument precision that head tank is joined is inadequate, the raw material addition is difficult to accurate control, affect the product quality of Chemical Manufacture, therefore, need a kind of high accuracy charging system of exploitation.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of high accuracy charging system is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of high accuracy charging system, comprise head tank storage tank and charge pump, also comprise measuring tank and the Weighing module that is fixed at the measuring tank bottom, the charging aperture of described measuring tank is communicated with the head tank storage tank by the material pipe with control valve, the discharging opening of described measuring tank is communicated with charge pump by the material pipe with control valve, and described charge pump, Weighing module and control valve all are connected with control module by data wire.The Weighing module arranged by measuring tank that capacity is less and coupling are set, can realize accurate measurement, overcome prior art head tank storage tank tonnage large, metering is difficult to the deficiency of accurately controlling.
As preferably, described control valve is air-operated solenoid valve.
As preferably, described charge pump is the frequency conversion gear pump.
As preferably, the bottom of described head tank storage tank is fixed with Weighing module, and described Weighing module is connected with control module by data wire.
As preferably, described control module is the PLC controller.
As preferably, the capacity of described measuring tank is 2% of head tank tank capacity.
The beneficial effects of the utility model are: the utility model metering precision is high, and the raw material addition is accurate, has guaranteed the quality of chemical industry product; Charging rate is fast, has improved operating efficiency.
The accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
In figure: 1, head tank storage tank, 2, charge pump, 3, measuring tank, 4, Weighing module, 5, control module.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of high accuracy charging system as shown in Figure 1, comprise the head tank storage tank 1 that capacity is 25 tons, charge pump 2, measuring tank 3, the capacity of described measuring tank 3 is 2% of head tank storage tank 1 capacity, the bottom of head tank storage tank 1 is equipped with Weighing module 4, described measuring tank 3 bottoms also are equipped with Weighing module 4, the charging aperture of described measuring tank 3 is communicated with head tank storage tank 1 by the material pipe with control valve, the discharging opening of described measuring tank 3 is communicated with charge pump 2 by the material pipe with control valve, described charge pump 2, Weighing module 4 all is connected with control module 5 by data wire with control valve, in the present embodiment, control valve is air-operated solenoid valve, described charge pump 2 adopts the frequency conversion gear pump, described control module 5 adopts the PLC controller.
When the utility model is used, by the storing weight range lower limit set of measuring tank 3, be 100kg, the upper limit is set as 400kg, when needs add raw material, control module 5 is controlled the control valve of head tank storage tank 1 bottom and is opened, raw material in head tank storage tank 1 flows in measuring tank 3, when the raw material weight in measuring tank 3 reaches 400kg, the control valve that control module 5 is controlled head tank storage tank 1 bottom is closed, control control valve and the charge pump 2 of measuring tank 3 bottoms simultaneously and open, to treating to add raw material in reinforced reactor; When the raw material total amount in measuring tank 3 is less than 100kg, the control valve that control module 5 is controlled head tank storage tank 1 bottom is opened again, in the process of feed supplement, the rotating speed of charge pump 2 is constant, until add raw material to 400kg, re-start again charging rate and regulate, so repeat, realize the quantitative interpolation of needed raw material.
Above-described embodiment is a kind of preferably scheme of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
