Description

Technical Field

[0001] The utility model relates to the technical field of grease sampling, in particular to a grease sampler. Background Art

[0002] In order to ensure the quality of oil and prevent defective oil from entering the market, it is often necessary to sample the oil (such as vegetable oil, etc.) in the oil tank. During the oil sampling process, a oil sampler is required to take samples in layers.

[0003] The sampling process of the existing grease sampler is to pre-select two nylon ropes on the upper cover, tighten a tube rope on the side of the upper cover when sampling, and slowly place the sampler into the sampling pool. When the sampler is placed at the required sampling position, tighten the middle valve rope to allow the sample to enter the sampler, then relax the valve rope, slowly pull up the lifting tube, and take out the sample.

[0004] However, based on the above sampling principles, after each sampling, when the sample in the sampling tube is poured out, a lot of samples will still remain on the inner wall of the sampling tube. Since sampling usually requires taking samples from the top, middle and bottom at 1 / 10, 1 / 2 and 9 / 10 of the oil depth in the tank respectively, in the subsequent sampling, the remaining samples from the last time will inevitably be mixed into the subsequent samples, which greatly affects the accuracy of the subsequent sampling. In order to improve the sampling accuracy, it is necessary to design a grease sampler that can reduce sample residue. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the prior art, the existing grease sampler usually needs to sample the grease three times, and the sampling depths are 1 / 10, 1 / 2 and 9 / 10 of the oil depth in the tank respectively. Since multiple samplings are required, the use of the existing grease sampler will cause the residual sample from the previous sampling to be mixed into the subsequent sample after the second sampling, which will greatly affect the accuracy of the subsequent sampling. In order to improve the relative accuracy of the sampling data.

[0029] For this purpose, a grease sampler is designed to reduce sample residue. Figure 1-Figure 3 As shown, a grease sampler in this embodiment is used for sampling stratified grease, such as vegetable grease. The grease sampler comprises an outer tube 1, a replacement component 2, a sealing cover 3 and a valve component 4, wherein Figure 6 As shown, a liquid hole 32 is opened on the cover 3, and the liquid hole 32 is the entrance for the sampled oil to enter the inside of the oil sampler, and the valve component 4 is connected to the cover 3, and is used to control the opening and closing of the liquid hole 32. When the oil sampler can reach the sampling depth, it can be opened to sample the oil. In addition, the outer cylinder 1 has an inner space, and the inner space is for the replacement component 2 to be placed. The cover 3 is detachably connected to the outer cylinder 1. For example, the cover 3 is threadedly connected to the outer cylinder 1, and the overall height of the replacement component 2 is equal to the distance between the inner top wall of the cover 3 and the inner bottom wall of the outer cylinder 1. In this way, when the replacement component 2 is built in the inner space, the cover 3 abuts against the replacement component 2 and presses the replacement component 2, so that the replacement component 2 can form a detachable structure through the outer cylinder 1 and the cover 3.

[0030] It should be noted that the outer cylinder 1, the sealing cover 3 and the valve component 4 are all made of 304 stainless steel. In this way, the grease will not react with the grease sampler, thereby avoiding changes in the grease composition during sampling and ensuring the quality of the grease.

[0031] When in use, since the replacement component 2 is a detachable structure and the replacement component 2 has the function of storing the sampling grease, it only needs to be replaced after each sampling. In this way, the sample residue during each sampling can be reduced, thereby improving the relative accuracy of the sampling data.

[0032] In order to facilitate understanding of the specific structure of the valve component 4, as shown in FIG. Figure 1 and 2 As shown, the cover 3 is provided with two sets of hooks 31 for hanging the nylon rope used for sampling. Figure 4 As shown, the valve component 4 includes a valve cover 41, a spring 42 and a hook 2 43, wherein the valve cover 41 abuts against the sealing cover 3 through the spring 42, and further seals the liquid hole 32, and the valve cover 41 and the sealing cover 3 are movably connected, so that the design requirement of opening the liquid hole 32 can be met. As for the hook 2 43, it is welded on the valve cover 41 for hanging the valve rope. The nylon rope and the valve rope are existing technologies and are not shown in the figure.

[0033] In this way, when the valve cover 41 is pulled by the valve rope, the liquid hole 32 is opened to allow the grease liquid to enter the inside of the replacement component 2.

[0034] To further explain, the valve cover 41 includes a cover plate 411, a blocking column 412, a center column 413 and a chassis 414, wherein the blocking column 412 is fixedly arranged at the bottom of the cover plate 411, and the number of the blocking columns 412 is the same as that of the liquid holes 32, and they are adapted to each other, so as to meet the initial blocking requirements, and the center column 413 is fixed between the chassis 414 and the cover plate 411, that is, the center column 413 is fixed at the center of the bottom of the cover plate 411, and the center column 413 is fixed at the center of the top of the chassis 414, and the spring 42 is arranged between the chassis 414 and the inner top wall of the cover 3, and is located on the outside of the center column 413.

[0035] In this way, when in use, during the sampling process, after the nylon rope is hung on hook one 31 and the valve rope is hung on hook two 43, the grease sampler is lowered by the nylon rope. After being lowered to the corresponding height, the valve rope is used to pull hook two 43 to allow the cover plate 411 and the blocking column 412 to rise. In this way, the liquid hole 32 is opened, and the grease sample at this height can enter the grease sampler through the liquid hole 32. After the sampling is completed, the grease sampler is also pulled up by the nylon rope. Subsequently, only the replacement component 2 needs to be replaced to reduce the sample residue during each sampling, thereby improving the relative accuracy of the sampling data.

[0036] In one embodiment, the replacement component 2 includes an inner cylinder 21, and the inner cylinder 21 has a storage area for storing sampled grease. Since the grease in the oil tank needs to be sampled three times, Figure 7 As shown, the inner cylinder 21 is composed of three groups, and the three groups of inner cylinders 21 are sequentially arranged from the outside to the inside, and are simultaneously abutted by the sealing cover 3. In this way, after sampling the innermost inner cylinder 21, the inner cylinder 21 is removed, and the grease remaining on the innermost inner cylinder 21 can be removed. In this way, the grease residue can be reduced and the relative accuracy of the grease sampling data can be improved.

[0037] Considering the inconvenience of replacing the inner cylinder 21, further, as a preferred solution of the present application, Figure 2 and 5 As shown, the replacement component 2 further includes a sleeve bag 22, and the sleeve bag 22 is sleeved in the inner tube 21. It should be noted that, at this time, the number of the inner tubes 21 is one group.

[0038] In this way, after each sampling, only the bag 22 in the replacement component 2 needs to be replaced to reduce the residual amount of the last grease sampling, thereby ensuring the relative accuracy of subsequent sampling and further ensuring the relative accuracy of the sampling data.

[0039] In order to better connect the bag 22, Figure 5 As shown, the inner tube 21 has a side 23, so that the bag 22 can be inserted into the inner tube 21 through the side 23 and is not easy to slip off, which can facilitate the insertion of the bag 22. When designed in this way, when the inner tube 21 is built into the inner space, the inner tube 21 can also partially press the bag 22 on the outer tube 1.

[0040] Furthermore, a plurality of circumferentially distributed air holes 24 are provided on the outer side of the lower portion of the inner tube 21 . When the bag 22 is put on the inner tube 21 , the air holes 24 provide space for the outflow of air in the inner tube 21 , so that the bag 22 can better fit to the inner side of the inner tube 21 .

[0041] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
