Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum product detection devices, and particularly relates to a sample splitting device for petroleum product detection. Background Art

[0002] Petrochemical products refer to the finished products of the petrochemical industry that use petroleum or natural gas as raw materials to manufacture chemicals, collectively called petrochemical products.

[0003] Petrochemical product samples are used for laboratory tests, taken from one or more parts of a whole, aiming to provide relevant information about the whole, usually as the basis for judging the whole. Sample splitting is to obtain samples for laboratory test analysis by reducing the sample volume without changing the nature of the sample.

[0004] Currently, when directly splitting samples from a sample bottle into other containers, products with viscosity are not convenient to operate with a pipette, and the products are likely to drip into the surrounding environment, causing environmental pollution in the experiment and inconvenient subsequent cleaning operations. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sample splitting device for petroleum product detection to solve the above-mentioned existing problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A sample splitting device for petroleum product detection, which includes a bracket, a transfer tank, a dropper, and a pressure booster. The transfer tank is a cylindrical container, and the axis of the transfer tank is horizontally arranged. The opposite ends of the transfer tank are both hinged on the bracket, and a feed port and a discharge port are opened on the side surface of the transfer tank. The dropper is installed on the discharge port, a sample bottle is screwed on the feed port, and the pressure booster is installed on the transfer tank and communicated with the inside of the transfer tank.

[0007] As a further description of the above technical scheme:

[0008] Two positioning grooves are opened on the bracket, and the opposite ends of the transfer tank are respectively clamped into the two positioning grooves.

[0009] As a further description of the above technical scheme:

[0010] Both the feed port and the discharge port are circular tubes, and the axis of the feed port coincides with the axis of the discharge port.

[0011] As a further description of the above technical scheme:

[0012] The diameter of the feed port is larger than the diameter of the discharge port.

[0013] As a further description of the above technical solution:

[0014] The supercharger is a manually inflated airbag.

[0015] As a further description of the above technical solution:

[0016] A protective sleeve is sleeved on the dropper.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0018] In the present utility model, by screwing the sample bottle containing the viscous sample onto the feed port of the transposition tank and rotating the transposition tank, the viscous sample flows into the transposition tank under the action of gravity. Since the transposition tank is in a conventional pressure state, the supercharger is used to pressurize the transposition tank to promote the viscous sample to flow out of the dropper into other containers for sub-sampling. The sub-sampling operation is simple and easy to control, avoiding the viscous sample dropping in the surrounding environment during the operation, and thus avoiding environmental pollution of the experiment.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4The utility model provides a technical solution: a sample dividing device for petroleum product detection, comprising a bracket 1, a transposition tank 2, a dropper 3 and a supercharger 4, wherein the transposition tank 2 is a cylindrical container, and the axis of the transposition tank 2 is arranged horizontally, the opposite ends of the transposition tank 2 are hinged on the bracket 1, and a feed port 5 and a discharge port 6 are provided on the side of the transposition tank 2, the dropper 3 is installed on the discharge port 6, a sample bottle 7 is screwed on the feed port 5, and the supercharger 4 is installed on the transposition tank 2 and communicated with the inside of the transposition tank 2;

[0027] The bracket 1 is provided with two positioning grooves 8, and the opposite ends of the transposition tank 2 are respectively inserted into the two positioning grooves 8, so that the transposition tank 2 can be rotated on the bracket 1, and the transposition tank 2 can be quickly disassembled and assembled on the bracket 1 by bending the bracket 1 to deform;

[0028] The feed port 5 and the discharge port 6 are both in the shape of a circular tube, and the axis of the feed port 5 coincides with the axis of the discharge port 6, so as to ensure that when the dropper 3 is located below the sample bottle 7, the viscous sample in the sample bottle 7 can flow into the transposition tank 2 as much as possible;

[0029] The diameter of the feed port 5 is larger than the diameter of the discharge port 6, so that the viscous sample in the sample bottle 7 can flow into the transposition tank 2 more conveniently, and the viscous sample flowing out of the discharge port 6 can also be controlled;

[0030] The booster 4 is a manually inflated airbag, which increases the convenience of operation;

[0031] The dropper 3 is covered with a protective sleeve 9 to prevent the sample in the dropper 3 from dripping.

[0032] Working principle: First, when in use, the sample bottle 7 containing the viscous sample is screwed onto the feed port 5 of the transposition tank 2. Secondly, the transposition tank 2 is rotated so that the viscous sample flows into the transposition tank 2 under the action of gravity, and the protective cover 9 is removed. Since the transposition tank 2 is in a normal pressure state, the pressure booster 4 is used to pressurize the transposition tank 2 to cause the viscous sample to flow out of the dropper 3 into other containers for sampling. The sampling operation is simple and easy to control, and the viscous sample is prevented from dripping into the surrounding environment during the operation, thereby avoiding pollution of the experimental environment. Finally, the transposition tank 2 can be removed from the bracket 1 by bending the bracket 1 to deform it, and the transposition tank 2 can be cleaned. After cleaning, the bracket 1 is also bent to deform and the end of the transposition tank 2 is inserted into the positioning groove 8.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
