Description

Technical Field

[0001] The utility model relates to the field of material taking and placing, in particular to a sampling bottle for deliquescent high melting point materials. Background Art

[0002] In existing techniques, deliquescent, high-melting-point materials are prone to reacting with moisture in the air during sampling. In high humidity environments, these materials can easily absorb moisture and deteriorate during the sampling process, directly affecting the sample's analytical results. Furthermore, due to their high melting points, samples tend to solidify while awaiting analysis, requiring significant time to reheat and melt. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a sampling bottle for deliquescent and high melting point materials which can prevent the materials from absorbing moisture and solidifying and hardening.

[0004] In order to solve the above problems, the present invention provides the following technical solutions:

[0005] A sampling bottle for deliquescent high-melting-point materials comprises a sample storage bottle, a sealing bottle cap is provided at the top bottle mouth of the sample storage bottle, the sealing bottle cap is provided with an air inlet pipe and an exhaust pipe, and the air inlet pipe and the exhaust pipe are both provided with valves; the side walls and the outer side of the bottom of the sample storage bottle are covered with a jacket, the jacket is detachably connected to the sample storage bottle, the jacket comprises an electric heating interlayer located on the inside and an insulation layer located on the outside of the electric heating interlayer, and the electric heating interlayer is electrically connected to a power supply.

[0006] It should be noted that the jacket and the sample bottle are detachably connected to facilitate the cleaning of the sample bottle. The detachable connection method can be as follows: the jacket is designed as two parts, one end of the two parts of the jacket is connected by a hinge, and the other end is provided with a snap-fit ​​device for opening and closing.

[0007] The sealed bottle cap is equipped with an inlet and an exhaust pipe. The inlet pipe is used to fill the sample bottle with a dry, inert gas, such as nitrogen. To use the sampling bottle, first place the clean sample bottle in the jacket and install the sealed bottle cap. Turn on the power supply to heat the bottle to dry out any moisture adhering to the bottle wall. Nitrogen is then introduced into the bottle, and air is expelled through the single exhaust pipe, leaving the entire bottle dry and oxygen-free. Close the valve of the inlet pipe and keep the electric heating power on. To take a sample, pierce the sealed bottle cap with a sharp sampling port and place the sample liquid. Nitrogen inside the bottle is discharged through the exhaust valve to ensure smooth sample flow. After sampling is complete, remove the sampling port. Throughout this process, the material entering the bottle is kept away from air and remains in a liquid state. This effectively prevents moisture absorption and solidification of the material.

[0008] The technical solution of the utility model also includes that the sampling bottle is provided with a temperature control device, the temperature control device includes a temperature sensor fixed inside the sample storage bottle, the temperature sensor is electrically connected to the controller, and the temperature of the temperature control device can be set to a temperature above the melting point of the sample being taken.

[0009] Furthermore, the technical solution of the present invention also includes that the power source is a group of lithium batteries, and the lithium batteries are electrically connected to the electric heating interlayer through a controller.

[0010] Furthermore, a charging port is provided at the bottom of the sampling bottle, which is electrically connected to the lithium battery through a controller. The controller is equipped with a charging system that can repeatedly charge the lithium battery.

[0011] The technical solution of the present invention also includes that the electric heating interlayer is electrically connected to a resistance heating tube, an electric heating belt, or an electric heating plate.

[0012] Preferably, an electric heating belt is electrically connected in the electric heating interlayer.

[0013] The technical solution of the present invention also includes the sealing bottle cap being a silicone sealing bottle cap that matches the size of the bottle opening. The silicone sealing bottle cap is made of silicone with good elasticity. In the prior art, the sampling port of the sampling device is a pointed structure. The thickness of the silicone sealing cap ensures that if it is pierced by the sampling port and then withdrawn, it will automatically seal the rupture and prevent exposure to the outside air.

[0014] The technical solution of the present invention also includes that the air intake pipe is connected to a nitrogen storage device.

[0015] The technical solution of the present invention also includes that the valve on the air inlet pipe is a nitrogen inlet valve, and the valve on the exhaust pipe is a one-way exhaust valve.

[0016] The technical solution of the present invention also includes that the sample storage bottle is a glass bottle.

[0017] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "center", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the purpose of simplifying the description of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] As can be seen from the accompanying drawings, a sampling bottle for deliquescent high melting point materials includes a sample storage bottle 1, which is a glass bottle. The top of the glass bottle is provided with a silicone sealing bottle cap 2 that matches the size of the bottle mouth. The silicone sealing bottle cap 2 is provided with an air inlet pipe 3 and an exhaust pipe 4 that pass through the silicone sealing bottle cap 2. The air inlet pipe 3 and the exhaust pipe 4 are both provided with valves; the air inlet pipe 3 is connected to a nitrogen storage device, the valve on the air inlet pipe 3 is a nitrogen inlet valve 5, and the valve on the exhaust pipe 4 is a one-way exhaust valve 6.

[0025] The sidewalls and bottom of the sample bottle 1 are covered with a jacket, which is detachably connected to the sample bottle 1. The jacket includes an inner electrically heated interlayer 7 and an insulating layer 8 outside the electrically heated interlayer 7. The electrically heated interlayer 7 is electrically connected to an electric heating plate. The electrically heated interlayer 7 is electrically connected to a group of lithium batteries 10 located at the bottom of the sample bottle via a controller 9. A charging port 11 is provided at the bottom of the sample bottle, which is electrically connected to the lithium batteries 10 via the controller 9. The sample bottle is provided with a temperature control device, which includes a temperature sensor 12 fixed to the inside of the sample bottle 1 and electrically connected to the controller 9.

[0026] The temperature control device can be set to a temperature above the melting point of the sample being sampled. Power is provided by a lithium battery 10, and the controller 9 is equipped with a charging system that allows for repeated recharging of the lithium battery 10. The silicone sealing cap 2 is made of highly elastic silicone, and its thickness ensures that if pierced and then withdrawn by the sampling port 13, it will automatically seal the breach, preventing exposure to air. An air inlet pipe 3 extending through the silicone sealing cap 2 allows for the introduction of dry nitrogen into the bottle.

[0027] When using a sampling bottle, first place a clean glass bottle into the jacket and install the silicone sealing bottle cap 2. Controller 9 activates the electric heating to dry out any moisture adhering to the bottle wall. Nitrogen is then introduced, and air is expelled from the one-way exhaust valve 6, leaving the entire interior of the glass bottle anhydrous and oxygen-free. The valve inlet pipe 3 is closed to maintain the electric heating. When sampling, the sharp sampling port 13 is used to pierce the silicone sealing bottle cap 2 and place the liquid sample. Nitrogen inside the bottle is expelled from the one-way exhaust valve to ensure smooth sample flow. After sampling is complete, the sampling port 13 is removed. Throughout this process, the material entering the bottle does not come into contact with air and remains in a liquid state, effectively removing moisture and air from the bottle.

[0028] This solution solves the problem of easy sample solidification through the electric heating function of the jacket and the rechargeable lithium battery, and solves the problem of easy deliquesce of materials when exposed to air through the design of the silicone sealing bottle cap, effectively preventing the material from absorbing moisture and solidifying, thereby improving sampling efficiency.

Without departing from the spirit and essence of the present invention, a person skilled in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions shall be within the scope of the present invention. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention shall be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
