Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and more specifically to the field of portable, electricity-free ceramic jar sampler technology. Background Technology

[0002] Newly brewed baijiu (Chinese white liquor) is harsh and pungent on the palate. It must be stored in earthenware jars for a period of time to soften its flavor and enhance its aroma. However, these earthenware jars are all handmade, and their internal structure naturally exhibits inhomogeneity during the manufacturing process. This results in variations in the content of metallic elements and the distribution of pore sizes. Furthermore, in practical applications, it has been found that after long-term static storage in earthenware jars, different sampling points exhibit subtle differences in the style of the liquor due to the influence of temperature, oxygen, or the precipitation of substances from the liquor. In actual sampling, using a liquor extractor only captures the surface liquid, introducing systematic errors for laboratory analysis and small-scale sample preparation. The existing patent discloses the following: Patent CN115046807A, entitled "Sampling Device," discloses the following: An outer tube, with its first end closed and its second end open, has multiple elongated holes arranged circumferentially along its sidewall; an inner tube, with a piston at its first end and a bottom valve at its second end. The piston closes the first end of the inner tube, and the bottom valve opens or closes the second end. The inner tube is fitted inside the outer tube, with its sidewall abutting against the sidewall of the outer tube. The sampler is inserted into a liquid, and the second end of the inner tube is then offset from the second end of the outer tube, allowing the liquid to flow naturally into the outer tube through the elongated holes. The first and second ends of the inner tube are then opened, and the inner tube is pushed to align its second end with the second end of the outer tube. Finally, the first and second ends of the inner tube are closed, transferring the liquid into the inner tube. This achieves sampling of heterogeneous liquids while maintaining consistency with the original liquid, thus improving sampling efficiency.

[0003] Patent publication number CN112781928B, entitled "Sampler," discloses the following: The sampler includes an operating table, a container, a rotating rod, a mud-collecting device, and a water-collecting device. The container is fixed to the bottom of the operating table; the container is divided into an installation area, an extension area, and a sampling area. A drive device and a water pump are installed in the installation area. The rotating rod includes a first end and a second end. The first end is connected to the drive device, and the second end extends through the extension area and the sampling area to the outside of the container, and the second end is equipped with a rotating blade. The mud-collecting device is equipped with a container cover that can rotate to the outside of the sampling area's cylinder wall and a receiving cavity located in the extension area; the container cover can rotate with the container and scoop mud samples during rotation, and place the mud samples into the receiving cavity after the container cover closes to the opening of the receiving cavity. The water-collecting device includes a suction head, a water inlet pipe connecting the suction head and the water pump inlet, and a water-collecting container installed on the operating table; the water-collecting container is connected to the water pump outlet through a guide pipe. This application enables simultaneous sampling of water and mud.

[0004] The sampler disclosed in the aforementioned patent has a complex structure and high manufacturing and usage costs. Utility Model Content

[0005] The purpose of this utility model is to provide a portable, electricity-free ceramic jar sampler in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model provides a portable, electricity-free ceramic jar sampler, including a wine filter, a liquid level measuring device, and a wine negative pressure check valve. The liquid level measuring device is a flexible tube. The wine filter is connected to the bottom of the liquid level measuring device. The wine negative pressure check valve is located on the top side of the liquid level measuring device. The outlet of the wine negative pressure check valve is connected to an outlet pipe. The parts of the wine filter and the wine negative pressure check valve that come into contact with the wine are made of SUS304 stainless steel.

[0007] Specifically, this solution comprises a three-element core structure: a wine filter, a level gauge, and a wine negative pressure check valve. The wine flows from the wine filter through the level gauge into the wine negative pressure check valve. The valve's primary purpose is to provide negative pressure, powering the wine extraction process. It is designed to operate without electricity, making it suitable for use in high-safety, explosion-proof areas such as wine cellars. All parts in contact with the wine in this system are made of SUS304 stainless steel and food-grade silicone.

[0008] This solution is simple to operate, highly portable, and can accurately determine sampling sites, while also pre-filtering the wine. Practical verification has shown that the device can more accurately collect wine samples from various points on the ceramic jar, and the obtained samples can be directly used for chromatographic analysis, avoiding the risk of capillary column clogging and overcoming the risk of damage to the ceramic jar caused by traditional metal sampling instruments.

[0009] In one embodiment, the two ends of the one-way negative pressure valve are connected to the liquid level measuring device and the liquid outlet pipe respectively via metal clips.

[0010] In one embodiment, the wine liquid one-way negative pressure valve includes a housing, and a wine liquid inlet one-way valve and a wine liquid outlet one-way valve are arranged inside the housing along the direction of medium flow. Both the wine liquid inlet one-way valve and the wine liquid outlet one-way valve are connected inside the housing by elastic hinges.

[0011] Specifically, the one-way negative pressure valve for wine is equipped with metal clips at both ends for connection, ensuring the airtightness of the system. The valve contains an inlet check valve and an outlet check valve. When the housing is squeezed by external force, the wine flows along the media flow direction into the outlet check valve.

[0012] In one embodiment, the wine filter includes an outer metal wire mesh, a PP cotton filter sleeved inside the metal wire mesh, and a diatomaceous earth filter cake layer sleeved inside the PP cotton filter. The middle part of the diatomaceous earth filter cake layer is a filtrate cavity, and the top of the filtrate cavity is connected to a liquid level measuring device.

[0013] Specifically, the main purpose of a wine filter is to perform coarse filtration of the wine in the earthenware jar, ensuring that solids and impurities are blocked outside the filter.

[0014] The wine passes through the metal mesh of the wine filter to remove larger particulate impurities. Then it passes through a PP cotton filter and a diatomaceous earth filter cake layer to remove visible impurities. Finally, the clean wine enters the filtrate cavity of the filter and, under the negative pressure generated by the wine negative pressure check valve, enters the liquid level measuring device.

[0015] In one embodiment, the liquid level measuring device is made of food-grade silicone tubing, and scale strips are provided on the outer wall of the liquid level measuring device along its length.

[0016] Specifically, the material is made of food-grade silicone, and its main purpose is to measure the liquid level in the ceramic jar. It has scale values ​​on the outside, and specific points (such as upper, middle, and lower) can be accurately sampled through numerical calculation.

[0017] In one embodiment, the sum of the length of the liquid level gauge at the bottom of the liquid level gauge and the depth of the wine filter is 180 cm.

[0018] In one embodiment, a counterweight is provided at the bottom of the level gauge near the outside of the wine filter or at the bottom of the wine filter.

[0019] In one embodiment, the counterweight is made of SUS304 stainless steel.

[0020] Specifically, the lower end of the silicone tube or the bottom of the wine filter is equipped with a counterweight made of SUS304 stainless steel to ensure that the soft silicone tube can be vertically immersed in the wine.

[0021] In one embodiment, the outlet pipe is equipped with a switch valve at the end away from the wine filter.

[0022] Specifically, the liquid level measuring device is equipped with a switch valve located far from the end of the wine filter, so as to avoid having to close the switch valve at any time to end the wine extraction process.

[0023] In one embodiment, the liquid outlet pipe is made of food-grade silicone.

[0024] The beneficial effects of this utility model are as follows: 1. The most significant feature of this utility model is that it overcomes the risk of bumping and breaking the ceramic jar due to traditional metal sampling instruments. It can accurately locate different sampling points to ensure the representativeness and rigor of the sampling. Combined with a filter, it can filter out solid impurities brought by the storage of ceramic jars. The obtained wine sample can be directly used for chromatographic analysis, avoiding capillary blockage. Moreover, it is small, lightweight and portable, which can simplify the operation process and greatly improve the operation efficiency.

[0025] 2. This utility model features simple operation, high portability, and precise determination of sampling sites, as well as pre-filtration of the wine. Practical verification has shown that this device can more accurately collect wine samples from various points on the ceramic jar, and the obtained samples can be directly used for chromatographic analysis, avoiding the risk of capillary column blockage and overcoming the risk of damage to the ceramic jar caused by traditional metal sampling instruments.
