Description
Technical Field
The invention belongs to the technical field of chemical production, and particularly relates to an online sampling device for cement paste production and a using method.
Background
The mucilage is a practical common material for bonding, sealing and the like. In the case of encapsulating circuits or integrated circuits, the curing of the paste used is either by UV curing or moisture in air. In the production process of the mucilage, sampling detection is carried out by installing a branched sampling tube on a production pipeline and installing a valve on the sampling tube. During sampling, the mucilage left in the sampling pipe is solidified and the sampling pipe is blocked if the position of the valve is close to the main pipeline; if the valve is positioned close to the sampling pipe opening, part of the previous batch of samples remains in the sampling pipe, and the accuracy of the samples is influenced.
Disclosure of Invention
In order to solve the technical problems, the invention provides an online sampling device for mucilage production and a using method, 1) a production line is modified: a sampling hole is formed in the side wall of a main discharging pipeline of the mucilage production line, and a flange plate is welded on the side wall and is aligned with the sampling hole; a feed port of a valve is directly connected to the flange plate, a discharge port of the valve is connected with a peristaltic pump, and a discharge port of the peristaltic pump is connected with a sampling pipeline; the sampling pipeline is hard;
2) at the time of sampling: opening a valve and starting a peristaltic pump, discharging part of the solidified colloid in the sampling pipe out of the pipe by using the pressure of a main discharging pipe and the pressure of the peristaltic pump, and collecting; then, collecting and sampling normal mucilage;
the sampling device is a sampling tank, and the sampling tank structurally comprises a closed hard shell;
the hollow part in the sampling tank is divided into two independent cavities by a partition plate, one cavity is a slag receiving cavity, and the other cavity is a sample reserving cavity; the top of the slag receiving cavity is provided with a feed inlet and an exhaust outlet, and the bottom of the slag receiving cavity is provided with a slag cleaning port capable of being opened and closed; the bottom of the sample reserving cavity is provided with a switchable discharge hole; the upper part of the clapboard is provided with a communicating hole, and the slag receiving cavity is communicated with the sample reserving cavity through the communicating hole;
during sampling, a feed port of the sampling tank is connected with the sampling pipe, and an exhaust port is opened; part of the solidified colloid enters the slag receiving cavity from the feed inlet; after the slag receiving cavity is filled with the normal mucilage and reaches the height of the intercommunicating pore, the mucilage which subsequently enters the feed inlet flows into the sample reserving cavity from the intercommunicating pore; when extracting the mucilage sample, opening a discharge hole and an exhaust port of the sample reserving cavity, and discharging the mucilage from the sample reserving cavity;
3) and after sampling is finished, closing the peristaltic pump and the valve, and at the moment, reserving the mucilage in the sampling pipeline, naturally curing the mucilage and plugging the sampling pipeline.
The principle of the scheme is that the valve is close to the main discharging pipe by opening the hole of the main discharging pipe close to the main discharging pipe. Because the flange inner hole is bigger, the degree of depth is shallower, can not produce the stock.
The sampling pipeline is long, the previous mucilage sample is remained in the sampling pipeline, and the mucilage sample is solidified at the position of the pipe orifice. The solidified part plugs the pipeline, so that air is prevented from entering the pipeline and then entering the main pipeline through a small gap of the valve.
Because of the presence of the solidified portion, the solidified portion is extruded by means of a peristaltic pump when the pressure of the main pipe is not sufficient to press out the solidified portion at the time of sampling.
In the sampling tank, through its specific structure, make the solidification part that flows out earlier and the mucilage remaining part when taking a sample the time before get into and connect the sediment chamber to by the sample pressure of this time sampling at the bottom of the chamber, newly sample flows into from the intercommunicating pore and reserves the appearance chamber. Because the age of the mucilage is higher, the mucilage in the sampling tank is more stable, and the mucilage in the two cavities can not be mixed unless the sampling tank is turned on one side.
The mucilage left in the sampling pipeline after sampling is naturally cured, and the plugging effect is achieved.
The device and the method are used for online sampling, so that the influence on the quality of the produced product is avoided. Meanwhile, the accuracy of the sampled sample is high.
