Description

Technical Field

[0001] The present invention relates to the technical field of detection, and particularly relates to an automated prickly ash oil extraction tank for auxiliary detection and its usage method. Background Art

[0002] During the current extraction process of prickly ash oil, sampling valves are usually pre-installed on the extraction tank or pipeline, and operators regularly open the valves to collect samples; the collected samples need to go through pretreatment steps such as filtration and dilution, and then are sent to the laboratory to use equipment and methods such as gas chromatography-mass spectrometry (GC-MS), high performance liquid chromatography (HPLC), and ultraviolet spectrophotometer to detect key indicators such as the aroma content of volatile oils and amide substances.

[0003] Although this method can meet the basic quality control requirements, due to the uneven distribution of components during the extraction process of prickly ash oil (such as the stratification of volatile oils and other components), the representativeness of the samples during sampling is insufficient, affecting the accuracy of the detection results; in addition, relying on manual operation methods has low efficiency and is difficult to achieve intelligent control of the extraction process, restricting the further improvement of process optimization and product quality. Summary of the Invention

[0005] The present invention is achieved through the following technical solutions: An automated prickly ash oil extraction tank for auxiliary detection, including an extraction tank, on the outer wall of the extraction tank, a first sampling pipeline, a second sampling pipeline, and a third sampling pipeline are respectively arranged at intervals from bottom to top.

An arc-shaped block is connected to the moving plate, and a number of protrusions cooperating with the slag separation plate are arranged on the arc-shaped block. An annular block is also arranged in the first sampling pipeline, the second sampling pipeline, and the third sampling pipeline. The moving plate is connected to the annular block through a connecting rod. A sealing member is also arranged on the sliding hole.

[0009] Further, the sealing member includes flexible sealing cloths arranged on both sides of the sliding hole. Each flexible sealing cloth is connected to the moving plate, and the two flexible sealing cloths are used to cover the sliding hole.

[0010] Further, a guiding pipe is spirally arranged in the confluence pipeline. The liquid inlet end of the guiding pipe is communicated with the third sampling pipeline, the first sampling pipeline and the second sampling pipeline are communicated with the outer wall of the guiding pipe, and the liquid outlet end of the guiding pipe is communicated with the composite cavity.

[0013] Further, a sealing disc is also arranged at a part of the protrusion.

[0014] Further, the inclination angle of the sloping plate is 30° - 45°.

[0015] Further, annular grooves with the same number as the slag separation holes are also opened on the slag separation plate. The slag separation holes are circular, the slag separation holes and the annular grooves are concentric, and a sealing gasket cooperating with the annular groove is arranged at the bottom of the sealing disc.

[0016] A usage method of an automated prickly ash seed oil extraction tank for auxiliary detection includes the following steps: S1: Ensure that the slag separation plate is in a closed state; S2: Start the heating program of the extraction tank; S3: Set the sampling sequence through the controller; S4: Open the slag separation channel; S5: Pass the oil through the slag separation plate; S6: Take samples in sequence; S7: After sampling is completed, reset and clean the slag separation plate; S8: Close the sampling valve.

Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments and the attached drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0024] Embodiment 1

[0025] As Figures 1 to 9 shown, an automated prickly ash seed oil extraction tank for auxiliary detection includes an extraction tank 1. The outer wall of the extraction tank 1 is respectively and spacedly provided with a first sampling pipeline 2, a second sampling pipeline 3 and a third sampling pipeline 4 from bottom to top. The three sampling pipelines are connected through a confluence pipeline 5. The bottom of the confluence pipeline 5 is connected to a composite block 6. A composite cavity is provided in the composite block 6. The confluence pipeline 5 is directly connected to the composite cavity, and a sampling port is provided on the composite block 6.

[0026] In the prior art, a sampling valve is generally provided on the extraction tank 1. However, the sampling valve can only obtain samples from specific areas. During the extraction process of prickly ash oil, the composition distribution is uneven, so the extracted samples are not representative enough, affecting the accuracy of the detection results.

[0027] In this application, three sampling pipes are arranged at intervals from top to bottom in the extraction tank 1. The three sampling pipes are respectively located in the upper, middle, and lower layers of the extraction tank 1, and the positional relationship of the upper, middle, and lower layers is based on Figure 1 a certain direction. These three sampling pipes are respectively the first sampling pipe 2, the second sampling pipe 3, and the third sampling pipe 4. A sampling valve is provided on each sampling pipe, so that the three sampling pipes can obtain the prickly ash oil at the corresponding levels. The three sampling pipes are connected through a confluence pipe 5. The bottom of the confluence pipe 5 is connected to a composite block 6. A composite cavity is provided in the composite block 6. The confluence pipe 5 is directly connected to the composite cavity. The prickly ash oil in the three sampling pipes flows into the composite cavity in sequence for mixing. A stirring mechanism can also be provided in the composite cavity to make the mixture uniform. A sampling valve can be provided in each sampling pipe and can be automatically controlled by a controller provided on the extraction tank 1 to open the corresponding sampling valve in a certain order.

[0028] Embodiment 2

[0029] In the first sampling pipe 2, the second sampling pipe 3, and the third sampling pipe 4, slag separation plates 7 are added, and a pushing component is also provided in the first sampling pipe 2, the second sampling pipe 3, and the third sampling pipe 4. The pushing component is used to push out foreign objects stuck on the slag separation plates 7. The pushing component includes a sliding hole 8 communicating with the outside is opened at the top of the first sampling pipe 2, the second sampling pipe 3, and the third sampling pipe 4. Two sliding grooves 9 are provided on both sides of the sliding hole 8. The two ends of the moving plate 10 are respectively slidably arranged in the two sliding grooves 9, and one end of the moving plate 10 is placed outside the sliding hole 8, and the other end of the moving plate 10 is placed in the corresponding sampling pipe. A number of protrusions 11 cooperating with the slag separation plates 7 are provided on the moving plate 10. In Embodiment 2, the sliding hole is arranged at the top of the sampling pipe, and the gravity of the oil is used to prevent leakage. Due to the flow-limiting effect of the slag separation plate, the fluid can only slowly pass through the sampling pipe and enter the confluence pipe, and will not completely fill the pipe or form high pressure. Therefore, during the normal sampling process, the oil in the pipe always remains in a low-flow and non-full pipe state, effectively avoiding the risk of oil leakage from the top sliding hole.

[0030] Since the first sampling pipeline 2 is located at the bottom of the extraction tank 1, and Zanthoxylum bungeanum particles will settle at the bottom of the extraction tank 1, when sampling on the first sampling pipeline 2, fine Zanthoxylum bungeanum particles are likely to flow into the composite cavity, affecting the subsequent test results. The prior art does not consider mixing it evenly by stirring in the extraction tank 1 either, because Zanthoxylum bungeanum particles will also be mixed in. When finally sampling the sample at this stage, Zanthoxylum bungeanum particles will still enter the sample to be tested. Although the prior art also adopts the form of placing Zanthoxylum bungeanum in the extraction tank 1 through a hanging basket, and after heating is completed, taking out the Zanthoxylum bungeanum through the hanging basket, but in this process, in order to make the flavor of Zanthoxylum bungeanum play to the extreme, some processes will crush the Zanthoxylum bungeanum. Since it is with a certain degree of crushing, when heating, some Zanthoxylum bungeanum particles will flow to the bottom of the extraction tank 1.

[0031] Therefore, in order to avoid the occurrence of the above situation, in this application, slag separation plates 7 are added to the first sampling pipeline 2, the second sampling pipeline 3 and the third sampling pipeline 4 respectively, to prevent Zanthoxylum bungeanum particles from entering the sampling pipeline. However, in order to prevent some crushed Zanthoxylum bungeanum particles from getting stuck on the filter plate, a pushing component is also arranged in the three sampling pipelines. A part of the moving plate 10 is placed outside the sliding hole 8, that is, one end is placed outside the sampling pipeline and not inside the sampling pipeline, and the other end is placed inside the sampling pipeline. The sampling pipeline mentioned here refers to the first sampling pipeline 2, the second sampling pipeline 3 and the third sampling pipeline 4; a protrusion 11 that cooperates with the slag separation plate 7 is arranged on the moving plate 10, and the driving part drives the moving plate 10 to move on the sliding hole 8. The specific structure of the driving part can be a cylinder arranged on the outer wall of the sampling pipeline. The cylinder is connected with the moving component. Therefore, the cylinder can drive the moving plate 10 to move on the slide rail, and the moving component moves towards the slag separation plate 7, so that the protrusion 11 on the moving component cooperates with the filter holes of the slag separation plate 7 to push out the Zanthoxylum bungeanum particles stuck on the slag separation plate 7; It should be noted that a sealing disc 15 is also arranged at a part of the protrusion 11. An annular groove 16 is also opened around each slag separation hole on the slag separation plate 7. The slag separation hole is circular, and the slag separation hole and the annular groove 16 are concentric. A sealing gasket that cooperates with the annular groove 16 is arranged at the bottom of the sealing disc 15.

[0032] In this application, a sealing disc 15 is arranged at the protrusion 11. The purpose of the sealing disc 15 is to seal the slag separation holes on the slag separation plate 7. The slag separation plate 7 is composed of a plate body with a number of slag separation holes arranged on it. An annular groove 16 is also opened around each slag separation hole on the plate body. The slag separation hole is circular, and the slag separation hole and the annular groove 16 are concentric. A sealing gasket that cooperates with the annular groove 16 is arranged at the bottom of the sealing disc 15 to enhance the sealing effect, and it can act as a valve, so the structure of the sampling valve can be omitted.

[0033] Embodiment 3

[0034] The pushing component includes four sliding holes 8 communicating with the outside on the inner walls of the first sampling pipeline 2, the second sampling pipeline 3 and the third sampling pipeline 4. Chutes 9 are arranged on both sides of the sliding holes 8. The two ends of the moving plate 10 are respectively slidably arranged in the two chutes 9, and one end of the moving plate 10 is placed outside the sliding hole 8, and the other end of the moving plate 10 is placed in the corresponding sampling pipeline. An arc-shaped block 12 is connected to the moving plate 10, and a number of protrusions 11 cooperating with the slag separation plate 7 are arranged on the arc-shaped block 12. An annular block 18 is also arranged in the first sampling pipeline 2, the second sampling pipeline 3 and the third sampling pipeline 4. The moving plate 10 is connected to the annular block 18 through a connecting rod 19. A seal is also arranged on the sliding hole 8.

[0035] The seal includes flexible sealing cloth arranged on both sides of the sliding hole 8. Each flexible sealing cloth is connected to the moving plate 10, and the two flexible sealing cloths are used to cover the sliding hole 8. This can prevent the prickly ash oil from splashing out when flowing into the confluence pipeline 5. The sealing cloth is a flexible cloth that can support a certain liquid weight, has a sealing function, and the sampling pipeline is not in a full-pipe state, so the force it bears is not much and it can work normally. When the moving plate reciprocates, the sealing cloth expands and contracts like an "accordion fold" to maintain the sealing continuity.

[0036] The pushing component includes four arranged sliding holes 8. In this Embodiment 3, it is preferably set to four, and a moving plate 10 is slidably arranged on each sliding hole 8. An arc-shaped block 12 is connected to the moving plate 10, and a number of protrusions 11 are arranged on the arc-shaped block 12. The sampling pipeline is composed of a first straight pipe 20, a tapered pipe 21 and a second straight pipe 17, and the diameter of the tapered pipe 21 increases step by step in the direction of fluid flow. When the four arc-shaped blocks 12 contact, they form a complete circle. The arrangement order of the intervals of the protrusions 11 on this complete circle corresponds one by one to the arrangement order of the slag separation holes on the slag separation plate 7. The partial moving plates 10 placed outside are all connected to the annular block 18 through connecting rods 19. The annular block 18 is slidably sleeved on the second straight pipe 17, and the driving part drives the moving plate 10 to move by driving the annular block 18 to move. The annular block 18 is arranged on the third straight pipe to enable the annular block 18 to move smoothly, which has a better effect than arranging it on the tapered pipe 21.

[0037] The specific working principle of Example 3 is as follows: in the initial state, the four arc blocks 12 are combined and contacted to form a whole circle, and the protrusions 11 of the four arc blocks 12 after the whole circle are synthesized are aligned with the slag separation holes on the slag separation plate 7, and the protrusions 11 are placed in the slag separation holes. When sampling begins, the driving part, that is, the cylinder, drives the annular block 18 on the third straight tube to move. Since the annular block 18 is connected to the four movable plates 10 by the connecting rod 19, the annular block 18 can drive the four movable plates 10 to move when it moves. The movable plate 10 first drives the arc block 12 on the first straight tube 20 to move away from the slag separation plate 7. This step is to enable the protrusions 11 on the four arc blocks 12 to detach from the filter holes, and then the movable plate 10 continues to move to the conical tube 21. When moving on the conical tube 21, as the diameter of the conical tube 21 increases, that is, the slope of the inclined surface increases, the arc block 12 rises along the sliding hole 8, and the whole circle begins to separate, which can ensure that the liquid flow of the pepper oil is not affected.

[0038] Example 4

[0039] A guide tube 13 is spirally arranged in the confluence pipe 5, the liquid inlet end 22 of the guide tube 13 is connected to the third sampling pipe 4, the first sampling pipe 2 and the second sampling pipe 3 are connected to the outer wall of the guide tube 13, and the liquid outlet end 23 of the guide tube 13 is connected to the composite cavity. The pepper oil in the third sampling pipe 4 enters from the liquid inlet end 22 of the spiral guide pipe 13 and flows along the spiral path; the pepper oil in the second sampling pipe 3 and the first sampling pipe 2 is injected in sections through the opening of the outer wall. This design allows different layers of oil to gradually converge in the spiral motion, avoiding local concentration fluctuations caused by direct concentrated mixing; and the centrifugal force generated by the spiral flow can promote the lateral mixing of components of different densities and alleviate the stratification phenomenon.

[0040] It should be noted that a gas generating component for generating minute bubbles is provided on the guide pipe 13 .

[0041] A gas-producing component that produces tiny bubbles is arranged on the guide tube 13, and the gas-producing component can be a microporous aeration head. The purpose of generating bubbles is to allow the bubbles to move randomly to make up for the limitations of the spiral tube mixing (such as insufficient mixing at low flow rates) and make the mixing more thorough. And it is under the spirally arranged guide tube 13, that is, under the premise of flow, if the oil is in a static state, only the natural rise of bubbles will produce slight disturbances, and the mixing will be uneven; while the flowing oil can exert shear force on the bubbles, breaking them into smaller bubbles and forming turbulence, which significantly improves the mixing efficiency. Another point is that in static oil, bubbles are concentrated in local areas, resulting in uneven oxidation (such as air bubbles) or unbalanced distribution of volatile components; flowing oil can make the bubbles evenly distributed and reduce detection errors.

[0042] It should be noted that a diagonal plate 14 is provided at the connection of the first sampling pipeline 2, the second sampling pipeline 3 and the guiding pipe 13. The inclination angle of the diagonal plate 14 is 30°-45°. A diagonal plate 14 is provided at the liquid outlet end 23 of the first sampling pipeline 2 and the second sampling pipeline 3. The diagonal plate 14 can buffer the kinetic energy of the high-speed oil fluid, reduce local turbulence, make the oil fluid flow more smoothly after confluence, and is beneficial to subsequent mixing and detection.

[0043] Example 5

[0044] A method for using an automated prickly ash oil extraction tank for auxiliary detection includes the following steps: S1: Ensure that the slag separation plate 7 is in a closed state; S2: Start the heating program of the extraction tank 1; S3: Set the sampling sequence through the controller; S4: Open the slag separation channel; S5: Make the oil fluid pass through the slag separation plate 7; S6: Conduct sampling in sequence; S7: After sampling is completed, reset and clean the slag separation plate 7; S8: Close the sampling valve.

[0045] Further, step S1 further includes: S1.1: Combine the four arc-shaped blocks 12 into a complete circle; S1.2: Insert the protrusion 11 of the arc-shaped block 12 into the slag separation hole of the slag separation plate 7; S1.3: Until the slag separation channel is completely closed.

[0046] Further, step S4 further includes: S4.1: The air cylinder drives the annular block 18 to move, thereby driving the four moving plates 10 to slide along the first straight pipe 20 in the sampling pipeline; S4.2: Until the protrusion 11 of the arc-shaped block 12 exits from the slag separation hole.

[0047] Further, step S7 includes: S7.1: The air cylinder drives the annular block 18 to reset, the moving plate 10 moves along the conical pipe 21 in the sampling pipeline to reset, and waits for the arc-shaped blocks 12 to recombine into a complete circle; S7.2: Continue to move until the protrusion 11 is inserted into the slag separation hole to eject the prickly ash particles stuck in the hole.

[0048] Specific usage method: Ensure that the four arc-shaped blocks 12 are combined into a complete circle, and the protrusions 11 are inserted into the slag separation holes of the slag separation plate 7 to completely seal the slag separation channel; start the heating program of the extraction tank 1 to make the prickly ash oil reach the target extraction temperature and maintain stable flow; set the sampling sequence through the controller, and check whether the sampling valves and the cylinders of the pushing components are in the standby state; the cylinder drives the annular block 18 to move, driving the four moving plates 10 to slide along the first straight pipe 20, so that the protrusions 11 of the arc-shaped blocks 12 are withdrawn from the slag separation holes, opening the slag separation channel; the moving plates 10 continue to slide into the conical pipe 21. Due to the gradually expanding diameter of the conical pipe 21, the arc-shaped blocks 12 are pushed outward by the inclined surface and separated to form a four-petal open structure, ensuring that the oil liquid passes through the slag separation plate 7 without obstruction; the controller opens the target sampling valve in sequence, and the oil liquid flows into the confluence pipeline 5 after passing through the slag separation plate and finally enters the composite cavity for mixing; after sampling, the cylinder pulls the annular block 18 in the reverse direction, the moving plates 10 retract along the conical pipe 21, and the arc-shaped blocks 12 are recombined into a complete circle again; the protrusions 11 are inserted into the slag separation holes again to eject the prickly ash particles stuck in the holes, completing self-cleaning; close the sampling valve and prepare for the next sampling or enter the detection process. In the early stage, the prickly ash is put into the extraction tank through the hanging basket. After the extraction of the extraction tank is completed, the hanging basket is lifted, and the prickly ash in the hanging basket is also lifted. For the part of the prickly ash particles that have fallen to the bottom, the prickly ash particles can be processed by suction. The bottom can also be set in a conical shape, and a slag discharge port is set at the bottom. The conical shape can naturally guide the particles to slide to the slag discharge port. After the extraction of the extraction tank is completed, most of the prickly ash oil has been extracted at this time. The remaining prickly ash oil and prickly ash particles at the bottom are located at the slag discharge port. Open the slag discharge port to discharge the prickly ash, and the discharged liquid is put into a centrifugal separator, and the filtered clear liquid continues the next process. It should also be mentioned that the capacity of the prickly ash oil in the extraction tank in this application is specific, so each sampling pipeline is located in the corresponding oil layer. Sampling is only carried out one or two times during the whole working process, and not too much liquid is extracted. Therefore, there will be no situation where the liquid height is lower than the height of any set pipeline.

[0049] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
