Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampling device technology, specifically relating to a pollution-proof oil sampling device. Background Technology
[0002] Edible oil refers to animal or vegetable fats used in food processing, which are liquid at room temperature. Edible oils contain various chemical components, among which acid value is a key factor in assessing safety. Specifically, acid value refers to the content of free fatty acids in vegetable oils, quantified by the number of milligrams required to neutralize potassium hydroxide per gram of oil. Large grain depots store large quantities of grain and edible oil; therefore, regular sampling and testing of edible oil using sampling devices is crucial to ensure the quality of stored edible oil.
[0003] Currently, oil tanks are enormous and can reach depths of over ten meters. During long-term storage, edible oil tends to separate into layers, necessitating sampling from different depths. Sampling from the depths of oil tanks is very difficult, as there is a lack of specialized sampling equipment. Typically, a water pipe is inserted into the tank, with a water pump connected to the top of the pipe to suck out the edible oil from the depths of the tank.
[0004] However, during the insertion of the water pipe into the cooking oil, it passes through oil layers of varying depths, resulting in the pipe being pre-filled with oil at different depths. When the water pump starts operating, the oil already present in the pipe at the non-target depth must be expelled before the sample at the desired depth can be collected. This process is not only inefficient but also makes it difficult to accurately determine whether the oil at the non-target depth has been completely expelled, easily leading to contamination of the extracted sample with oil from the non-target depth, thus compromising the purity of the cooking oil sample. In other words, the oil at the non-target depth can contaminate the target cooking oil sample, adversely affecting the accuracy of subsequent testing.
[0005] Therefore, we propose a pollution-resistant oil sampling device to solve the above-mentioned technical problems. Utility Model Content
[0006] In order to solve the technical problems existing in the prior art, this utility model proposes a pollution-proof oil sampling device.
[0007] The technical solution adopted in this utility model is as follows:
[0008] A contamination-resistant grease sampling device includes a main support, an oil suction pipe, a water pump, and an oil outlet pipe. The main support includes a fixed base, a fixed rod, and a clamping assembly. The clamping assembly is located at the end of the fixed base, and the fixed rod is located below the fixed base. A connecting rod is fixedly sleeved on the lower part of the fixed rod, and an oil cover is provided on the connecting rod. The oil suction pipe passes through the fixed base and the oil cover and is rotatably connected to both the fixed base and the oil cover. The bottom of the oil suction pipe is sealed. A sampling tube is connected to the oil suction pipe inside the oil cover. The edge of the sampling tube abuts against the inner wall of the oil cover through a sealing gasket. An oil sampling hole is provided on the oil cover to cooperate with the sampling tube. The two ends of the water pump are respectively connected to the oil suction pipe and the oil outlet pipe. Both the oil suction pipe and the oil outlet pipe are stainless steel pipes.
[0009] In a further technical solution, the clamping assembly includes a fixing plate, a pressing plate, and an adjusting bolt. The fixing plate is connected to the end of the fixing seat, the pressing plate is arranged parallel to the fixing plate, and the adjusting bolt passes through the fixing plate and the pressing plate and is threadedly connected to both the fixing plate and the pressing plate.
[0010] In a further technical solution, a rotating handle is provided on the outer side wall of the upper part of the oil suction pipe.
[0011] In a further technical solution, a servo motor is installed on the fixed base, an active bevel gear is fixedly sleeved on the output shaft of the servo motor, and a passive bevel gear is fixedly sleeved on the oil suction pipe, with the active bevel gear and the passive bevel gear meshing with each other.
[0012] In a further technical solution, the oil suction pipe is provided with a rotary joint on the side near the water pump.
[0013] In a further technical solution, the oil suction pipe is provided with multiple sampling tubes with different orientations from top to bottom, and each sampling tube is covered with an oil cover and connected to a fixed rod by a connecting rod.
[0014] In a further technical solution, the sampling tube is tilted upwards.
[0015] In a further technical solution, clamping components are provided at both ends of the fixing base.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. This utility model avoids the cumbersome process of draining non-target depth edible oil, improving sampling efficiency. At the same time, it eliminates the need for manual judgment and removal of non-target oil layers, fundamentally avoiding the possibility of sample contamination, ensuring the purity and representativeness of the extracted edible oil samples, and thus guaranteeing the accuracy and reliability of the test results.
[0018] 2. This utility model has a sealing gasket at the edge of the sampling tube end. When the sampling tube and the oil hole are misaligned, the end of the sampling tube abuts against the inner wall of the oil cover through the sealing gasket to achieve a sealing effect. This effectively prevents edible oil of non-target depth from entering the oil suction tube from the sampling tube, ensuring that only edible oil of the target depth can enter the sampling tube through the oil hole during subsequent extraction operations, thus effectively guaranteeing the purity of the sample.
[0019] 3. This utility model, through the coordinated operation of a servo motor, an active bevel gear, and a passive bevel gear, not only achieves precise control of the rotation angle, ensuring accurate docking and staggering between the sampling tube and the oil sampling hole, but also reduces the labor intensity of operators and improves the convenience and efficiency of use.
[0020] 4. This utility model uses multiple sampling tubes with different orientations set up at the top and bottom. By precisely controlling the orientation of the oil suction tubes and sampling one by one from bottom to top, edible oil can be sampled at different depths, thereby gaining a more comprehensive understanding of the quality and distribution of the oil. This is crucial for ensuring the safety and quality of edible oil. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] See Figure 1 and Figure 2This utility model provides a pollution-proof oil sampling device, including a main support, an oil suction pipe 1, a water pump 2, and an oil outlet pipe 3. The main support includes a fixed base 4, a fixed rod 5, and a clamping assembly. The clamping assembly is located at the end of the fixed base 4, and the fixed rod 5 is located below the fixed base 4. A connecting rod 6 is fixedly sleeved on the lower part of the fixed rod 5, and an oil cover 7 is provided on the connecting rod 6. The oil suction pipe 1 passes through the fixed base 4 and the oil cover 7, and is rotatably connected to both the fixed base 4 and the oil cover 7. The bottom of the oil suction pipe 1 is sealed. A sampling pipe 8 is connected to the oil suction pipe 1 inside the oil cover 7. The edge of the end of the sampling pipe 8 abuts against the inner wall of the oil cover 7 through a sealing gasket. An oil sampling hole 9 is opened on the oil cover 7 to cooperate with the sampling pipe 8. The two ends of the water pump 2 are respectively connected to the oil suction pipe 1 and the oil outlet pipe 3. Both the oil suction pipe 1 and the oil outlet pipe 3 are stainless steel pipes.
[0027] This contamination-prevention oil sampling device is used to periodically sample edible oil from oil tanks to ensure the storage quality of the oil. Its specific usage method is as follows:
[0028] First, the oil suction tube 1 needs to be rotated to ensure that the sampling tube 8 on the oil suction tube 1 and the oil hole on the oil cover 7 do not intersect, preventing the mixing of edible oil from the target depth. Then, the oil suction tube 1 is inserted into the oil tank and clamped to the edge of the tank by the clamping assembly at the end of the fixing seat 4, ensuring stability during the sampling process. Next, the oil suction tube 1 is rotated again to align the position of the sampling tube 8 with the oil hole. At this point, the water pump 2 is started to extract the target edible oil from the depth of the oil tank for subsequent oil quality testing. During the insertion of the oil suction tube 1, because the edge of the sampling tube 8 is designed with a sealing gasket, when the sampling tube 8 and the oil hole are misaligned, the end of the sampling tube 8 abuts against the inner wall of the oil cover 7 through the sealing gasket, achieving a sealing effect. This effectively prevents edible oil from the target depth from seeping into the oil suction tube 1 through the sampling tube 8, ensuring that only edible oil of the target depth can enter the sampling tube 8 through the oil hole 9 during subsequent extraction operations, effectively guaranteeing the purity of the sample. Compared to existing technologies that use water pipes, this method avoids the tedious process of draining non-target oil layers, thus improving sampling efficiency. Furthermore, it eliminates the need for manual identification and removal of non-target oil layers, fundamentally preventing sample contamination and ensuring the purity and representativeness of the extracted oil samples, thereby guaranteeing the accuracy and reliability of the test results.
[0029] In one specific implementation, see Figure 1The clamping assembly includes a fixing plate 10, a pressing plate 11, and an adjusting bolt 12. The fixing plate 10 is connected to the end of the fixing base 4. The pressing plate 11 is arranged parallel to the fixing plate 10. The adjusting bolt 12 passes through the fixing plate 10 and the pressing plate 11 and is threadedly connected to both the fixing plate 10 and the pressing plate 11.
[0030] This anti-contamination grease sampling device, through the setting of the clamping assembly, uses the adjusting bolt 12 to drive the squeezing plate 11 to move, so that the squeezing plate 11, together with the fixing plate 10, is clamped at the edge of the oil tank, effectively ensuring the stability of this anti-contamination grease sampling device during the sampling process.
[0031] In one specific implementation, see Figure 1 A rotating handle 13 is provided on the outer side wall of the upper part of the oil suction pipe 1.
[0032] Rotating the handle 13 allows the oil suction pipe 1 to be rotated, thereby adjusting the orientation of the sampling pipe 8. This design not only makes the docking and offsetting operations between the sampling pipe 8 and the oil sampling hole 9 more convenient, but also allows the current orientation of the oil suction pipe 1 to be determined based on the orientation of the handle, thus effectively confirming whether the sampling pipe 8 and the oil sampling hole 9 are in a docked or offset state, which is beneficial for use.
[0033] In one specific implementation, see Figure 1 A servo motor 14 is mounted on the fixed base 4. An active bevel gear is fixedly sleeved on the output shaft of the servo motor 14. A passive bevel gear 16 is fixedly sleeved on the oil suction pipe 1. The active bevel gear and the passive bevel gear 16 mesh with each other.
[0034] Besides the traditional method of rotating the oil suction pipe 1 by rotating the handle 13, the rotation of the oil suction pipe 1 can also be easily achieved by using a mechanized control method. Specifically, through the coordinated operation of the servo motor 14, the active bevel gear, and the passive bevel gear 16, not only can the rotation angle be precisely controlled, ensuring that the docking and staggering operations between the sampling pipe 8 and the oil sampling hole 9 are always accurate, but the labor intensity of the operator is also reduced, and the convenience and efficiency of use are improved.
[0035] In one specific implementation, see Figure 1 The oil suction pipe 1 is provided with a rotary joint 17 on the side near the water pump 2.
[0036] By setting the rotary joint 17, the relative rotation function between the upper and lower parts of the oil suction pipe 1 is realized. Specifically, the lower part of the oil suction pipe 1 can rotate, thereby realizing the docking or offset operation between the oil suction pipe 1 and the oil suction port, while the upper part of the oil suction pipe 1 remains stationary, thereby effectively avoiding the possible rotation of the water pump 2 due to the rotation of the oil suction pipe 1.
[0037] In one specific embodiment, the oil suction pipe 1 is provided with multiple sampling pipes 8 with different orientations from top to bottom. Each sampling pipe 8 is covered with an oil cover 7 and connected to the fixed rod 5 by a connecting rod 6.
[0038] By using multiple sampling tubes 8 with different orientations at different heights and precisely controlling the orientation of the oil suction tube 1, edible oil can be sampled at different depths. This allows for a more comprehensive understanding of the oil's quality and distribution, which is crucial for ensuring the safety and quality of the edible oil. However, it is important to note that to avoid cross-contamination between oil samples from different depths, the sampling order is fixed: sampling from bottom to top. For specific operational instructions, please refer to [reference needed]. Figure 1 First, extract the cooking oil from the deepest point. After extraction, rotate the oil suction tube 1 to offset the lower sampling tube 8 from the sampling port, ensuring that the tubes at other depths are also offset. Then, continue extraction for a period of time to reduce the amount of cooking oil in the oil suction tube 1, ensuring that the liquid level is below the sampling tube 8 at the second depth after the water pump 2 stops working. Next, rotate the oil suction tube 1 again to align the sampling tube 8 at the second depth with the sampling port. (Refer to...) Figure 2 At this point, cooking oil is poured in, covering the remaining oil extracted earlier. Simultaneously, water pump 2 is restarted for extraction. Due to the continuous pouring of oil from the second depth, as long as the extraction speed is controlled to be less than the pouring speed, it can be ensured that the extracted oil is always from the second depth. Following the above steps, sampling operations are performed at each depth sequentially until the highest sampling position is reached. Throughout the process, the accuracy of sampling and the purity of the oil are ensured.
[0039] In one specific implementation, see Figure 1 and Figure 2 The sampling tube 8 is inclined upwards.
[0040] The sampling tube 8 is tilted upwards, ensuring that during sampling, the edible oil is not retained in the upper sampling tube 8 as it is drawn from below, thus avoiding contamination between edible oils at different depths. Furthermore, this tilted design facilitates the pouring of edible oil, ensuring that when the water pump 2 begins drawing oil from above, the newly poured oil quickly covers any remaining sample residue, and its covering speed exceeds the pumping speed. This ensures the purity of the sample during subsequent sampling, thereby guaranteeing the accuracy and reliability of subsequent test results.
[0041] In one specific implementation, see Figure 1 and Figure 2 The fixed base 4 is provided with clamping components at both ends.
[0042] By using two sets of clamping components, which are respectively clamped on both sides of the oil tank, the stability of this anti-contamination oil sampling device can be further improved during use.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
