Description

Sampling unit for concentrates preparation device

Field of the Invention

The invention relates to a concentrates preparation device, especially to a sampling unit for the concentrates preparation device using low pressure 5 and low boiling point.

Description of prior art

The boiling point of water decreases with the pressure, so water can be boiling with low temperature under low pressure, the boiling water changes io liquid water into water vapor, mist water vapor condenses on the interface between cool and hot, a lot of mist collects together to form water drop, and a lot of water drop collects together to form water flow.

So, there is provided with a device which can remove water from mixture using above principle, the device is a concentrates preparation device, which condenses hot water steam into liquid water, which is transformed to the container latter, thereby water content is reduced, so the concentrating function is achieved.

When the sampling unit takes samples of concentrates from the boiler, concentrates in the boiler can be taken out through the sampling bore of the sampling unit, the movable rod can take samples freely with the help of gas permeable passage for keeping the pressure balance of ends of the movable rod.

In order to increase detecting accuracy, the handle is rotated fast before sampling, referring to Fig.2, the remnant sample left in the sampling bore is thrown out due to the centrifugal force, then the sampling bore is upwards with the help of the direction mark on the handle; the movable rod is drawn out to the withdraw position after the sampling bore is full of concentrates, detector detects the concentration of the sample in the sampling bore, or detector detects the concentration of the sample in the glassware dropped from the sampling bore due to the gravity force after rotating the movable rod to make the sampling bore be downwards. The movable rod is pushed back to the insertion position after sampling process. In order to increase the next detecting accuracy, the handle is rotated fast before sampling, the remnant sample left in the sampling bore is thrown out due to the centrifugal force.

Fast rotating the handle before detecting is inevitably inconvenient, and it 15 adds a process in detecting process, it is a time-consuming.

Summary of the present invention

The object of the invention is to provide a sampling unit for the concentrates preparation device so as to solve the above problem.

Therefore, the invention provide a sampling unit for the concentrates preparation device, the sampling unit comprises a base body, a movable rod, a limiting pin, a sampling chamber, a sampling bore, an axle sleeve and an isobaric chamber. The sampling chamber passes through the upper and lower surfaces of the base body; the isobaric chamber is configured to be a cylindrical blind bore, the isobaric chamber passes through the front surface of the base body and passes through the front and back surfaces of the sampling chamber. The axle sleeve has an interference fitting with the isobaric chamber, the movable rod hermetically slidingly mates with the axle sleeve, the limiting pin fastened on the movable rod mates with the front surface or the back surface of the 5 sampling chamber, inside the base body is provided with a gas permeable passage, of which the head and tail ends respectively communicate with the isobaric chamber and the outside. The sampling unit further includes a refreshing passage, of which the head end extends to the bottom portion of the sampling bore of the movable rod, the tail end of the refreshing passage 10 extends away from the handle and extends to exterior cylindrical surface of the movable rod.

When the sampling bore is inside the sampling chamber, the tail end of the refreshing passage is inside the sampling chamber, boiling concentrates in the sampling chamber flows into the refreshing passage through the tail end of the refreshing passage and then flows into the sampling bore, or boiling concentrates in the sampling chamber flows into the refreshing passage through the sampling bore and then flows out from the tail end of the refreshing passage, therefore the boiling concentrates in the boiler can freely flow into or out of sampling bore, thus the concentrates in the sampling bore is refreshing in real time, the density of the concentrates in the sampling bore is identical to the density of the concentrates in the boiler.

When the sampling bore is inside the axle sleeve and near to the front surface of the axle sleeve, the tail end of the refreshing passage is inside the axle sleeve and near to the back surface of the axle sleeve, that is the sampling bore and the tail end of the refreshing passage are inside the axle sleeve, thus concentrates in the sampling bore or in the refreshing passage is sealed by the axle sleeve and is isolated from the concentrates in the boiler.

When the sampling bore is outside the base body, the tail end of the refreshing passage is inside the axle sleeve and near to the front surface of the axle sleeve, because the tail end of the refreshing passage is sealed by the axle sleeve, concentrates in the sampling bore do not flow out, it is limited in the sampling bore.

Profitably, the tail end of the refreshing passage is located below the sampling bore, and the refreshing passage is configured to be a cylinder.

Advantageous Effects Because concentrates in the sampling bore is refreshing in real time, it is no need to fast rotate the hand firstly when taking samples of concentrates in the boiler.

When the sampling bore is inside the axle sleeve and near to the front surface of the axle sleeve, the sampling bore and the tail end of the refreshing passage are inside the axle sleeve, so the sampling bore and the refreshing passage do not communicate the boiler with the outside, the boiler is still in sealing condition.

When the sampling bore is outside the base body, because the tail end of the refreshing passage is inside the axle sleeve, concentrates in the sampling bore is limited therein so as to be detected conveniently by detector.
