Abstract

The invention discloses a driving tank of a calibrating-free dosing machine. The driving tank comprises an upper cover body, a lower cover body, an elastic driving membrane and locking bolts, wherein the upper cover body and the lower cover body are hollow, the upper cover body corresponds to the lower cover body, closed containing space is formed in a way that the upper cover body and the lower cover body are fixed through the locking bolts, openings are respectively formed in the upper cover body and the lower cover body, and the elastic driving membrane is arranged in the containing space and is used for dividing the containing space into a medicine storage cavity and a water storage cavity of which the volumes are equal. According to the driving tank of the calibrating-free dosing machine and the calibrating-free numerical control dosing machine, provided by the invention, the structure is simple, the output medicine dosage can be automatically and accurately controlled, and the service life is long.

Description

technical field [0001] The invention belongs to the field of automatic dosing, and in particular relates to a calibration-free dosing machine drive tank and a calibration-free numerical control dosing machine. Background technique [0002] Flotation is one of the most important beneficiation methods. According to statistics, 90% of non-ferrous metal mines are processed by flotation. Flotation is also widely used in the selection of mineral raw materials such as rare metals, precious metals, ferrous metals, non-metals such as media. The addition of flotation agents is an important link in the flotation production process. The size and accuracy of the addition amount directly affect the quantity, quality and benefit of the product. Traditional manual adjustment methods are neither accurate nor timely. In order to solve the problems existing in the manual adjustment method, people invented the flotation automatic dosing control device, such as figure 1 As shown, however, thi...

Traditional manual adjustment methods are neither accurate nor timely

In order to solve the problems existing in the manual adjustment method, people invented the flotation automatic dosing control device, such as figure 1 As shown, however, this ordinary flotation automatic dosing control device uses a conventional solenoid valve automatic dosing machine. This conventional solenoid valve automatic dosing machine needs to be installed with a high-level tank for self-flow, and each dosing point needs frequent calibration. , increased a lot of labor costs and maintenance costs, and after a long period of use due to the direct contact of the solenoid valve that controls the flow rate, the magnetic valve automatic dosing machine is extremely prone to corrosion and leakage, valves and pipes leaking, leaking, blockage, etc. serious problem

[0003] Moreover, this traditional dosing system that relies on liquid level difference self-flow and valves to control the output of medicine, because it completely relies on the medicine in the high-level tank to flow downward, this leads to the following problems: (1) Due to the high-level medicine The difference in liquid level of the tank makes the flow rate per unit time very inaccurate, so the dosing amount cannot be accurately measured, which increases the difficulty for the operator to operate, that is, the amount of feed, filtrate water and dilution water of each flotation machine None of them can be measured, and the feeding concentration is manually measured, so it is impossible to provide accurate information to the operator; (2) In addition, the dosing amount is manually adjusted through the valve, so the flotation effect cannot be guaranteed; (3) Due to different agents or the same The viscosity of different concentrations of the medicine is different, and the flow rate is also very different, so the operator needs to frequently calibrate each dosing point to calibrate the dosing amount of the medicine per unit time

[0004] In response to the above technical problems, people have invented diaphragm mechanical diaphragm metering pumps and plunger mechanical diaphragm metering pumps. Because the agents added are generally corrosive and contain particulate matter, and the solenoid valves or metering pumps are directly in contact with the agents. When the agent is corrosive, it is easy to corrode the solenoid valve or the metering pump, which not only affects the output amount of the drug, but also easily causes the equipment to run, emit, drip, and leak

At the same time, the traditional automatic dosing machine is inconvenient to clean. When the medicine with high viscosity is transported, it is easy to cause the pipeline for conveying the medicine to be blocked; it is easy to cause damage, failure, material leakage, blockage, mechanical damage, etc. of the mechanical diaphragm metering pump.

Moreover, each branch pair needs a metering pump, which leads to various problems such as increased operating energy consumption, complicated maintenance, and increased manufacturing costs.
