Description

Technical Field

[0001] The utility model relates to the technical field of detection sampling, in particular to a sampling device for preparing biodiesel. Background Technique

[0002] Biodiesel is a kind of biomass energy. It is close to petrochemical diesel in physical properties, but different in chemical composition. Biodiesel is a mixture of complex organic components with extremely high oxygen content. These mixtures are mainly some organic substances with large molecular weights, almost including all kinds of oxygen-containing organic substances, such as esters, ethers, aldehydes, ketones, phenols, organic acids, alcohols, etc. Composite biodiesel is made from waste animal and vegetable oils, waste engine oil and by-products of refineries, and then added with catalysts, and synthesized through special equipment and special processes;

[0003] When biodiesel is produced, it is necessary to sample and detect biodiesel in different links according to process requirements. The prior art patent CN220794739U discloses a diesel sampler, which includes a sampling tube. Scale lines are arranged on the outer surface of the sampling tube. Sampling mechanisms are arranged on the upper and lower sides of the sampling tube. A fixing mechanism is arranged on the right side of the sampling mechanism; the sampling mechanism includes a filtering part and an extraction part. The filtering part is located below the sampling tube, and the extraction part is located above the filtering part; the fixing mechanism includes a connecting part and a fixing part. The connecting part is located above the extraction part, and the fixing part is located on the right side of the connecting part. By rotating the rotating block arranged on the fixing part, the threaded rod rotates under the drive of the rotating block. While the threaded rod rotates, the threaded rod moves to the left, and the left end face of the threaded rod presses and fixes the outer side face of the pulling rod, so that the pulling rod will not move after extracting diesel, so that diesel will not overflow from the sampling tube, and then the amount of diesel after sampling will not deviate, affecting the sampling accuracy. When in use, a hose is placed in the oil tank as the sampling pipeline, and then the diesel is sampled and extracted by the upward movement of the piston. However, when this device is used for diesel sampling in a place with a large diesel storage tank, the hose is long, and the diesel cannot be effectively extracted into the sampling tube, and it is not convenient to carry and transport, and it is inconvenient to use.

The first check valve 16 and the second check valve 17 are respectively inserted into the access port of the fuel inlet and outlet joint 2 and the discharge joint 15 of the fuel inlet and outlet joint 2, and the first check valve 16 and the second check valve 17 are arranged in opposite directions. When it is necessary to extract and detect diesel, the immersion hose 3 is placed in the oil tank, and then the oil is pumped into the diesel sampling cylinder 1 through the immersion hose 3 by the negative pressure principle. When it is necessary to discharge, under the one-way flow action of the first check valve 16, the diesel cannot pass through the first check valve 16 and can only push the second check valve 17 to discharge for detection;

[0027] When the diesel sampling cylinder 1 is used as a portable and movable container, the diesel in the diesel sampling cylinder 1 can be automatically sealed and stored.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, a pushing assembly is provided to push out the diesel when it is necessary to discharge the diesel. The pushing assembly is vertically inserted into the upper end of the diesel sampling cylinder 1. The pushing assembly includes a pressing push rod 4. The lower end of the pressing push rod 4 vertically and movably penetrates and is inserted into the upper end of the diesel sampling cylinder 1. A pushing piston 5 is provided at the lower end of the pressing push rod 4 inserted into the diesel sampling cylinder 1. The pressing push rod 4 can control the pushing piston 5 to push downward, so that the air pressure in the space below the pushing piston 5 in the diesel sampling cylinder 1 increases, realizing the discharge of the diesel by pushing the second check valve 17;

[0030] Both the first check valve 16 and the second check valve 17 are common small liquid check valves in the prior art;

[0031] The suction assembly is set to perform non - manual suction when sucking diesel through the immersion hose 3. The suction assembly is arranged inside the pressing push rod 4. The suction assembly includes a switching groove 6 and several extraction grooves 11. The switching groove 6 is arranged at the center of the lower end of the pushing piston 5. An annular collecting box 10 is provided at the upper end of the pressing push rod 4. One side of the annular collecting box 10 is connected and inserted with an air suction pipe 14.

Several extraction grooves 11 are symmetrically opened. A rod groove is vertically opened at the center inside the pressing push rod 4. A positioning rod 7 is vertically and movably inserted into the rod groove. The lower end of the positioning rod 7 is inserted into the switching groove 6 and a blocking piston 8 is horizontally arranged. The depth of the switching groove 6 is greater than the thickness of the blocking piston 8. The thickness of the blocking piston 8 is greater than the diameter of the extraction groove 11. When the blocking piston 8 is at the uppermost position inside the switching groove 6, the extraction groove 11 communicates with the upper part inside the diesel sampling cylinder 1 through the switching groove 6. When the air suction pipe 14 is connected to the suction pump, the annular collecting box 10 can perform negative pressure suction on the inside of the diesel sampling cylinder 1 through several extraction grooves 11. The suction pump is a common small pump suction device in the prior art. The connection method between the suction pump and the air suction pipe 14 can be a common snap - type or threaded quick - connector. At this time, the air pressure inside the diesel sampling cylinder 1 decreases. The lower part of the immersion hose 3 is placed inside the diesel storage tank, and diesel enters the diesel sampling cylinder 1 by pushing the first one - way valve 16 through the immersion hose 3;

[0032] According to the amount of diesel to be extracted inside the diesel sampling cylinder 1, the pressing push rod 4 and the pushing piston 5 are moved to an appropriate height in advance, and then a bolt is inserted on one side of the diesel sampling cylinder 1 to fix the positions of the pressing push rod 4 and the pushing piston 5;

[0033] A spring groove is opened at the lower end inside the rod groove. One side of the positioning rod 7 located inside the spring groove is sleeved with an adaptation spring 9, and the lower end of the adaptation spring 9 is in contact with the upper end of the blocking piston 8. A threaded ring 13 is vertically arranged at the upper end of the annular collecting box 10.

When extracting diesel, the blocking piston 8 is misaligned with the opening of the extraction groove 11 inside the switching groove 6, which is convenient for the air suction pipe 14 to pump out the air inside the diesel sampling cylinder 1. When enough diesel is extracted inside the diesel sampling cylinder 1, the positioning screw block 12 is rotated to thread - move inside the threaded ring 13. At this time, the positions of the blocking piston 8 and the positioning rod 7 cooperate with the adaptation spring 9 to descend, and the blocking piston 8 blocks the positions of several extraction grooves 11, so that diesel will not leak when the diesel sampling cylinder 1 is transferred. The immersion hose 3 can be separated from the diesel sampling cylinder 1 and wait for the next use.
