An automatic precise dosing machine

Abstract

The invention discloses an automatic and precise dosing machine, comprising a liquid medicine transfer body, and a water wheel transmission module, a flow variable collection group, a flow control group and a data processing point are arranged inside the liquid medicine transfer body; The data entry module enters the ratio of the rotational speed value to the value of the matching valve opening. After the chemical water liquid is put into the chemical water liquid transfer machine through the conveying pipeline, the water wheel transmission module will be sent to the water tank transmission module due to the chemical water liquid through the rotational speed sensing acquisition module. The speed of rotation in the direction of rotation driven by the gradual inflow is captured, and according to the transmission signal receiving module, the transmission data of the flow variable collection group is sent to the speed-adapted flow processing module, and the corresponding water valve opening demand is obtained through data processing and comparison with the relationship between speed and flow. Afterwards, the PLC signal control module sends an opening and closing signal to the water valve opening control module, so that the water valve opening control module adjusts the opening to the required rotational speed of the waterwheel transmission module.

Description

technical field [0001] The invention relates to the technical field of medicament input equipment, in particular to an automatic precise dosing machine. Background technique [0002] In the treatment environment of sewage treatment / coal mine flotation, the chemical dosing machine is usually used to do the treatment in a quantitative manner. In the prior art, a dosing device for sewage treatment equipment (publication number: CN111846296A) can be used to disperse lumps, but there is a technical problem that the dosing amount is not enough to satisfy the precision; The feeding device and method (publication number: CN113264327A) can solve the problem of the original manual dosing, labor-intensive, easy agglomeration of the medicament, affecting the flocculation effect of the medicament, but there is also the technical problem that the dosage is not enough to meet the precision ; An automatic quantitative dosing device (publication number: CN112850192A) can use the weight of w...

Problems solved by technology

In the prior art, a dosing device for sewage treatment equipment (public number: CN111846296A) can use the dosing device to break up lumps, but there is a technical problem that the dosing amount is not enough to meet the precision; a medicine The feeding device and method (public number: CN113264327A) can solve the traditional manual dosing, which is labor-intensive, and the medicine is easy to agglomerate, which affects the flocculation effect of the medicine, but there is also a technical problem that the dosing amount is not enough to meet the precision ;An automatic quantitative dosing device (public number: CN112850192A) can use the weight of water to finally determine the moving distance of the medicine board, so that the amount of medicine that is suitable for the current water volume can be added, but there is also the problem of insufficient dosing. Satisfy precise technical issues

Due to the presence of many impurities in the sewage treatment / coal mine flotation environment of the conventional dosing device, when it acts on a small amount of dosing, the flow meter is prone to errors due to environmental influences, and cannot maintain its flow measurement range, resulting in dosing The quantitative accuracy of the flowmeter is limited, so that the dosing amount is not enough to meet the precision. Constrained by this, it will directly affect the treatment completion in the sewage treatment / coal mine flotation process after long-term operation. Therefore, we propose an automatic precision Dosing machine
