Description

A high-viscosity liquid storage and quantitative discharge device

technical field

The invention relates to a liquid storage and quantitative discharge device, in particular to a high-viscosity liquid storage and quantitative discharge device.

Background technique

In daily life, laboratory operations and production in various industries, it is common to store and quantitatively discharge highly viscous liquids. For example, when we take quantitatively high-viscosity liquids such as honey and syrup in our daily life, no matter whether we use direct pouring or use other utensils such as spoons to extract from wide-mouth containers, it is inevitable that the liquid will flow out and adhere to the container wall. And the phenomenon of the desktop is difficult to remove, which brings serious inconvenience to life. Furthermore, some highly viscous substances such as asphalt, residual oil, grease, ointment, etc. widely exist in chemical and chemical laboratories, and their storage and quantitative extraction have always troubled the majority of laboratory workers; especially at low temperatures, such substances The viscosity becomes higher and even stops flowing, making it more difficult to discharge and extract. Therefore, no matter in daily life, laboratory operation or industrial production, there is an urgent need for a convenient and easy-to-use high-viscosity liquid storage and quantitative discharge device.

So far, known devices and technologies have made certain contributions to solving the above problems, but still cannot completely eradicate the above problems.

Patent document CN202054234U——"A Pourer for Viscous Liquid" draws on the teapot spout and the principle of mechanical cutting to provide a viscous liquid pourer that can quickly cut off the source of viscous liquid without causing the viscous liquid to flow out. It is simple and easy to use in daily life, but it cannot discharge the viscous liquid quantitatively, and at low temperature, the liquid in the bottle may have too high viscosity to be poured out.

Patent document CN102458685A - "Quantitative Discharge Device and Method for Highly Viscous Materials" provides a device and method for high-precision discharge of high-viscosity materials under high pressure, but there are many components, complex devices, and high power consumption. The disadvantage is that it is not suitable for daily life, laboratory operations or general industrial applications.

Patent Document CN201548432U——"Viscous Liquid Sampling Device" adopts a vacuum pumping device and a sampling bottle to cooperate with the sampling of viscous liquid. There is also the natural phenomenon that the viscosity of the liquid increases as the temperature decreases, and how to extract the liquid from the sampling bottle Efficient removal of the viscous fluid was not well thought out.

Detailed ways

Taking the quantitative discharge of high-viscosity asphalt in a petrochemical laboratory as an example, the invention is concretely implemented.

The high-viscosity bitumen storage and quantitative discharge device consists of an electromagnetic heating device (2), a piston-sleeve mechanism (3), a screw mechanism (4) and a discharge conduit (1). The electromagnetic heating device (2) is composed of an electromagnetic heating jacket (5) powered by an external AC voltage and wires. The electromagnetic heating jacket (5) is arranged circumferentially outside the sleeve (8), and the axial length of the electromagnetic heating jacket (5) can be determined according to actual conditions. The top of the sleeve (8) is provided with a liquid filling port (7) and a discharge nozzle (9). The liquid filling port (7) is connected to the cover (6) through a sealing thread, and the discharge nozzle (9) is connected to the connecting pipe (10) and discharge pipes (11) are connected to form an asphalt discharge passage. The bottom of the piston (12) is made into a spherical groove larger than 1/2 hemisphere, and is connected with the screw rod (15) through the piston connector (13), and the top of the piston connector (13) is a convex head larger than 1/2 hemisphere, and The radius is the same as the radius of the spherical groove at the bottom of the piston (12). The screw mechanism (4) is composed of a screw rod (15), a support frame (14) and a hand wheel (16). The screw rod (15) and the support frame (14) are connected by precision threads, and the support frame (14) and the device sleeve ( 8) Fixed connection.

The whole device can be placed vertically in the laboratory through the bracket as shown in the attached figure, a certain amount of high-viscosity asphalt can be added to the sleeve (8) of the device through the liquid filling port (7) at one time, and the cover (6) should be tightened , the connecting pipe (10) is tightened by clamps, so that the storage of high-viscosity asphalt can be realized. When it is necessary to quantitatively discharge asphalt into the test tube or beaker, the test tube or beaker can be conveniently moved to the vicinity of the device, the clip on the connecting pipe (10) can be removed, and the handwheel (16) can be rotated for a certain number of turns, the piston (12) If the moving distance is constant, the quantitative discharge of asphalt can be realized conveniently. When the asphalt needs to be discharged to a large fixed container, the quantitative discharge operation can be realized by moving the discharge pipe (11).

When the ambient temperature is low, the viscosity of the asphalt is high and it is difficult to discharge. It can be heated by connecting an external power supply. As the temperature of the asphalt increases, the viscosity decreases, and the high-viscosity asphalt can still be discharged quantitatively.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements can also be made, and these improvements should also be considered It is the protection scope of the utility model.
