Technical Field

[0001] The utility model relates to the technical field of methanol storage, in particular to a methanol storage barrel which is convenient for sampling. Background Art

[0002] Methanol is flammable and explosive and should be stored away from open flames and heat sources. During indoor use, transportation, and handling, ensure adequate ventilation and avoid direct sunlight. Methanol should be stored in a cool, well-ventilated, dedicated warehouse away from sources of fire and heat. The container must be kept sealed and separated from oxidants, acids, alkali metals, and other substances. Mixing should never be done.

[0003] According to a Chinese patent with the announcement number CN107585468A, a ton barrel for storing methanol is disclosed.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 are within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 2 The utility model provides a technical solution: a methanol storage barrel that is convenient for sampling, comprising a buffer base 1, a storage barrel body 3 and a diversion valve tube 5. The storage barrel body 3 is arranged above the buffer base 1, and a guardrail 2 fixed to the buffer base 1 is arranged above the storage barrel body 3. The guardrail 2 can wrap the storage barrel body 3 to prevent the storage barrel body 3 from being collided and squeezed, and ensure that the storage barrel body 3 has a safety protection function. The top of the storage barrel body 3 is connected with a liquid inlet 301, and one side of the bottom of the storage barrel body 3 is connected with a liquid outlet valve tube 302. The liquid inlet 301 is connected to the top of the storage barrel body 3, and a sealing cover is threadedly connected to the liquid inlet 301. When the sealing cover is opened, methanol is conveniently injected into the storage barrel body 3. When the methanol in the storage barrel body 3 needs to be discharged, the methanol can be discharged by opening the valve on the liquid outlet valve tube 302; a conductive wire 101 for grounding is fixed on the outside of the buffer base 1, and an anti-collision pad 102 is provided at the corner between the guardrail 2 and the storage barrel body 3;

[0027] A liquid level gauge 303 and a thermometer 304 are respectively installed on the upper side of the storage barrel body 3. The liquid level gauge 303 and the thermometer 304 are installed on the upper side of the storage barrel body 3, so that the storage barrel body 3 can monitor the liquid level and temperature of the stored methanol solution, making it convenient for personnel to quickly understand the storage amount and storage temperature of the methanol solution.

[0028] See also Figure 1-Figure 7 A conduit 4 is fixed above the storage barrel body 3, and a sampling bottle 401 is slidably connected to the inside of the conduit 4. A through hole is opened on one side of the bottom of the sampling bottle 401, and a push rod 402 is fixed on the top of the sampling bottle 401. The upper end of the push rod 402 is movably connected to a pull rod 405;

[0029] The circumferential side of the conduit 4 is obliquely connected to a drainage valve tube 5. A clamping mechanism 6 is provided below the drainage valve tube 5. The clamping mechanism 6 includes a fixing seat 601 mounted on the guardrail 2. The fixing seat 601 has an inner cavity in the middle, and grooves 602 are provided on both sides of the inner cavity. A positioning seat 604 is docked in the inner cavity. The bottom end of the drainage valve tube 5 is inserted into the inner cavity of the fixing seat 601. A measuring cylinder 607 for receiving the methanol solution is provided above the positioning seat 604.

[0030] A communication port is provided on one side of the bottom of the conduit 4, and a sealing ring is provided on the outer side of the sampling bottle 401 to abut against the inner wall of the conduit 4. When the sampling bottle 401 moves downward along the conduit 4 and the through hole on one side of the sampling bottle 401 is aligned with the communication port at the bottom of the conduit 4, the methanol solution in the storage barrel body 3 is introduced into the sampling bottle 401. When the sampling bottle 401 moves up and down along the inside of the conduit 4, the sealing ring on the outer side of the sampling bottle 401 slides against the inner wall of the conduit 4, thereby preventing the methanol solution in the sampling bottle 401 from flowing back downward into the storage barrel body 3.

[0031] A sliding groove 603 is provided below the fixed seat 601 near the groove 602, a baffle 605 is fixed on one side of the positioning seat 604, and the baffle 605 is slidably connected to the sliding groove 603, a guide rod 606 is fixed to the bottom end of the positioning seat 604, and the guide rod 606 slides through the bottom of the fixed seat 601; an operating cavity is provided on one side of the fixed seat 601 near the sliding groove 603, and a protrusion 8 is rotatably connected in the operating cavity, and a handle 7 connected to the protrusion 8 is provided on the outside of the fixed seat 601.

[0032] During implementation, the measuring cylinder 607 is docked and placed on the positioning seat 604 in the inner cavity of the fixed seat 601, and the protrusion 8 is rotated by turning the handle 7. When the protrusion 8 turns, it can press the baffle 605 upward, so that the baffle 605 can drive the positioning seat 604 and the measuring cylinder 607 to move upward, so that the top opening of the measuring cylinder 607 is docked with the bottom end of the drainage valve tube 5, and the top wall of the measuring cylinder 607 is tightly abutted against the upper side wall of the inner cavity of the fixed seat 601, so that the clamping mechanism 6 can drive the measuring cylinder 607 and the drainage valve tube 5 to complete the sealed docking;

[0033] Then, by pressing down the pull rod 405, the sampling bottle 401 at the bottom of the top rod 402 is moved to the bottom of the conduit 4, so that the methanol solution enters the sampling bottle 401 along the connecting port of the conduit 4. Then, by pulling up the pull rod 405, the through hole of the sampling bottle 401 is aligned with the upper end of the inclined drainage valve tube 5. At this time, by rotating the valve on the drainage valve tube 5, the methanol solution in the sampling bottle 401 is discharged along the drainage valve tube 5 and injected into the measuring cylinder 607, thereby achieving anti-evaporation and anti-leakage sampling of methanol, ensuring the safety of the methanol sampling operation;

[0034] On the contrary, reversing the handle 7 upward drives the protrusion 8 to rotate in the opposite direction, so that the protrusion 8 is separated from the squeezing support on the baffle 605. At this time, the baffle 605, the positioning seat 604, the guide rod 606 and the measuring cylinder 607 fall back due to the action of gravity, and the baffle 605 slides along the slide groove 603 to prevent the positioning seat 604 from deflecting when moving up and down. At the same time, the guide rod 606 slides along the bottom of the fixed seat 601 to ensure that the positioning seat 604 has a smooth guiding effect when moving up and down. When the top opening of the measuring cylinder 607 is separated from the bottom end of the diversion valve tube 5, the staff inserts their hand into the groove 602 to hold the measuring cylinder 607, thereby facilitating the discharge of the measuring cylinder 607 storing methanol.

[0035] See also Figure 3 and Figure 4 A U-shaped opening is provided above the top rod 402, and strip grooves are symmetrically provided on both sides of the inner wall of the U-shaped opening. A spring 404 is fixed inside the strip groove, and a clamping block 403 that slides with the strip groove is fixed at the bottom end of the spring 404. The bottom end of the pull rod 405 is connected to the U-shaped opening of the top rod 402 through a rotating shaft, and a C-shaped bracket 406 is fixed to the top of the catheter 4.

[0036] During specific implementation, when the pull rod 405 is used to pull the sampling bottle 401 to the upper side of the catheter 4, the pull rod 405 is flipped around the rotating shaft, so that the pull rod 405 drives the rotating shaft to move upward and squeezes the clamp 403, so that the clamp 403 squeezes the spring 404 in the strip groove. At this time, the pull rod 405 can be flipped to be perpendicular to the catheter 4, and the pull rod 405 can be pressed and clamped into the C-shaped structure of the holder 406, which is convenient for placing the pull rod 405 horizontally and reducing the occupied space. At the same time, the pull rod 405 stuck in the holder 406 can limit the sampling bottle 401 at the bottom end of the top rod 402 to prevent the sampling bottle 401 from moving downward.

[0037] To sum up, a sealing cover is threadedly connected to the liquid inlet 301. When the sealing cover is opened, it is convenient to inject methanol into the storage barrel body 3. When the methanol in the storage barrel body 3 needs to be discharged, the methanol can be discharged by opening the valve on the liquid outlet valve pipe 302. The conductive wire 101 on the outside of the buffer base 1 is connected to the grounding position to allow the static electricity on the surface of the storage barrel body 3 to be introduced into the earth, ensuring that the methanol storage barrel has an anti-static effect, and an anti-collision pad 102 is set at the corner between the guardrail 2 and the storage barrel body 3 to ensure that the guardrail 2 can buffer the storage barrel body 3 when it is hit, preventing the storage barrel body 3 from being squeezed. The contents not described in detail in this description belong to the existing technology known to professional and technical personnel in this field.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
