Description

A device for treating carbon tetrachloride in ground water and its working method

technical field

The invention belongs to the field of sample processing equipment, and in particular relates to a device for dosing and distributing carbon tetrachloride in ground water and a working method thereof.

Background technique

Sample shearing is a common process in the processing of carbon tetrachloride samples. The main equipment for sample shearing is the sample shearing machine, but the common sample shearing machine has many deficiencies.

The main disadvantages of ordinary sample shears are:

1. The working precision is not high

The main reason for the low processing accuracy is that on the one hand, the processing size is manually measured by the operator with an ordinary steel ruler, and the accuracy is difficult to guarantee; on the other hand, the asynchronous motor is used to drive the chain transmission mechanism, which not only has low positioning accuracy, but also easily causes shearing. The mechanical deviation of the cut surface, which increases with the width of the processed sample.

2. The operation is cumbersome and error-prone

The sample shearing machine requires manual operation, and the control of the shearing action needs to be completed manually, which takes up human resources and is prone to errors.

3. High energy consumption and low efficiency

The power system of the sample shearing machine generally uses an ordinary asynchronous motor, which starts and stops continuously during the shearing process, resulting in high energy consumption and low efficiency.

The traditional automatic sample shearing machine developed from the ordinary sample shearing machine uses a relay as the controller. Its control system is more complicated, and the parameters are not flexible to change. A large number of wiring reduces the reliability of the system, and the maintenance rate is high, which reduces the production efficiency.

With the continuous rapid growth of my country's economy, the society's demand for various samples continues to grow, and higher requirements are placed on the accuracy of sample processing. In addition, with the increasing competition among enterprises and the increase in human resource costs, In order to occupy a favorable position in the competition, manufacturers not only ensure the accuracy of sample processing, but also put forward higher requirements for the efficiency of sample processing.

Based on the above situation, sample production and processing enterprises urgently need high-precision and high-efficiency production equipment. Sample shearing machine is one of the key production equipment of sample processing enterprises. In the foreseeable future, the development of sample shearing machines will be that some enterprises with strong funds will spend huge sums of money to purchase new CNC sample shearing machines; quite a number of small and medium-sized enterprises do not have enough funds and hope to improve the quality of the original equipment through technical transformation. fulfil requirements. There is a large market demand for upgrading and transforming ordinary sample shearing machines or traditional automatic sample shearing machines to improve work efficiency, shearing accuracy, and reduce energy consumption.
