In the process of extracting relevant physicochemical and microbial nucleic acids from mash fermentation products, mash pretreatment is an essential step, and mash filtration is an indispensable part of mash pretreatment.

[0003] At present, the filtration of mash is usually carried out with a separate filter, and the operations before and after the filtration of the mash (mixing, oscillation, liquid collection, etc.) are mainly carried out in the sample bottle. Therefore, during the filtration, the mash in the sample bottle needs to be transferred to the filter, and after the filtration is completed, the mash in the filter needs to be transferred to the sample bottle. In this way, the mash sample needs to be repeatedly tossed in different containers during the entire sample pretreatment process. The operation is cumbersome and the detection efficiency is low. When the amount of samples to be pre-treated is large, the workload cannot be ignored, and the back-end automated detection technology cannot be efficiently matched. Moreover, the samples are prone to change during the repeated transfer process, which will cause the accuracy of the test results to be low, seriously affecting the final test effect.

[0060] Example 1

[0061] This embodiment provides a filtering device for fermented grains samples, which is used to perform batch filtering on solutions in a plurality of sample bottles placed in a tray 2, and comprises:

[0062] An operating table 1, wherein the operating table 1 has a first position and a second position which are staggered with respect to each other in a horizontal direction;

[0063] The storage table 3 is arranged on the operation table 1. A plurality of film storage slots 31 are arranged on the storage table 3. When the storage table 3 and the tray 2 are vertically opposite, each film storage slot 31 is respectively opposite to each sample bottle. Each film storage slot 31 is provided with a storage segment 311 and a positioning segment 312 distributed from top to bottom. The inner diameter of the storage segment 311 is equal to the inner diameter of the sample bottle, and the inner diameter of the positioning segment 312 is equal to the outer diameter of the bottle mouth of the sample bottle. A plurality of filter discs 9 are stacked in the storage segment 311, and the lower surface of the bottom filter disc 9 is flush with the bottom surface of the storage segment 311, and the diameter of the filter disc 9 is larger than the inner diameter of the storage segment 311.

[0064] The pushing assembly 4 is arranged on the operating table 1. The pushing assembly 4 includes a lifting plate 41 and a plurality of push rods 42 arranged on the bottom surface of the lifting plate 41. The number of the push rods 42 is consistent with the number of the film storage slots 31. When the storage table 3 and the lifting plate 41 are facing each other vertically, each push rod 42 is facing each film storage slot 31 respectively.

[0065] The first driving mechanism 5 is used to drive the storage platform 3 to rise and fall;

[0066] The second driving mechanism 6 is used to drive the pushing component 4 to rise and fall;

[0067] The third driving mechanism 7 is used to drive at least one of the storage table 3 and the lifting plate 41 to move horizontally above the first position and the second position.

[0068] The wine mash sample filtering device provided by the embodiment of the utility model provides a storage slot 31 in the storage table 3, so that the storage table 3 can pre-store more filter discs 9, which provides a basis for realizing continuous automatic filtration of samples; and by dividing the storage slot 31 into a storage segment 311 and a positioning segment 312, and limiting the inner diameter of the positioning segment 312 to be equal to the outer diameter of the bottle mouth of the sample bottle, and the inner diameter of the storage segment 311 to be equal to the inner diameter of the bottle mouth of the sample bottle, so that the positioning segment 312 can just cover the bottle mouth of the sample bottle, which can not only ensure that the sample bottle and the storage slot 3 are in contact with each other, but also ensure that the sample bottle and the storage slot 3 are in contact with each other. 1, which provides a basis for the accurate pushing of the filter disc 9, and when the positioning section 312 covers the bottle mouth of the sample bottle, the inner wall of the storage section 311 is just connected with the inner wall of the sample bottle, so that the filter disc 9 can be pushed into the sample bottle smoothly and unimpeded, and the operability is good; and by setting the pushing component 4, not only can the filter disc 9 in the storage slot 31 be pushed into the sample bottle to realize the automatic loading of the filter disc 9, but also the filter disc 9 pushed into the sample bottle can be pushed to the bottom of the sample bottle to perform solid-liquid separation and realize automatic filtration of the sample solution.

[0069] The wine mash sample filtering device can filter the sample solution in the sample bottle without transferring the sample solution. It is simple to operate and highly efficient. It can also avoid changes in the sample solution during the transfer process, thereby ensuring accurate inspection results. In addition, the filter plate 9 loading and sample solution filtration of the device are both performed by automated equipment, which can reduce labor input and greatly improve detection efficiency.

[0070] The filtering device for the fermented grains sample provided by the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

[0071] like Figure 1 As shown, the filtering device for the mash sample includes an operating table 1, a support frame 8, a storage table 3, a pushing component 4, a first driving mechanism 5, a second driving mechanism 6 and a third driving mechanism 7.

[0072] In this embodiment, the operating table 1 is used to place the tray 2, so as to facilitate the automatic loading of the filter disc 9 and the automatic filtering of the sample solution. Figure 1 The operating table 1 is a conveyor belt mechanism, which has a first position and a second position along the conveying direction of the conveyor belt mechanism. The first position and the second position are staggered with each other, and the tray 2 can be placed at the first position or the second position.

[0073] In this embodiment, the support frame 8 is mainly used to provide support or installation for various components of the filter device. Figure 1The support frame 8 includes two vertically arranged support plates, which are respectively arranged on both sides of the conveyor belt mechanism, namely the first support plate 81 and the second support plate 82. The storage table 3, the pushing assembly 4, the first driving mechanism 5, the second driving mechanism 6 and the third driving mechanism 7 are arranged on the first support plate 81 or the second support plate 82.

[0074] Specifically, see Figure 3 In this embodiment, the push assembly 4 is disposed on the first support plate 81 through the second drive mechanism 6 and is located at the first position of the conveyor belt mechanism. The second drive mechanism 6 is used to drive the push assembly 4 to rise and fall, so as to realize the feeding of the filter discs 9 one by one through the push assembly 4 and push the filter discs 9 to automatically filter the sample solution.

[0075] The second driving mechanism 6 may be an existing linear driving mechanism. Figure 3 In this embodiment, the second driving mechanism 6 can select the existing ball screw linear module composed of guide rails, ball screws, motors, slides and other components. Its specific structure can be Figure 3 The structure shown in FIG. 1 is for illustrative purposes only and will not be described in detail here.

[0076] See also Figure 3 In this embodiment, the push assembly 4 includes a lifting plate 41 and a plurality of push rods 42. The lifting plate 41 is a rectangular plate structure and is fixed to the slide seat of the ball screw linear module in a horizontal direction, but the utility model is not limited thereto. For example, the shape of the lifting plate 41 can also be circular, elliptical, and other regular or irregular shapes. The plurality of push rods 42 are vertically arranged on the bottom surface of the lifting plate 41, and the number and position of the push rods 42 are adapted to the number and placement of the sample bottles on the tray 2. For example, see Figure 3 The sample bottles in the tray 2 are arranged in a 5×5 square matrix, and correspondingly, the push rods 42 on the lifting plate 41 are also arranged in a 5×5 square matrix, so that when the lifting plate 41 and the tray 2 are facing each other up and down, each push rod 42 is just facing each sample bottle, and when the second driving mechanism 6 drives the lifting plate 41 to descend, each push rod 42 can be respectively extended into each sample bottle.

[0077] See also Figure 1 In this embodiment, the storage table 3 is disposed on the second support plate 82 through the first driving mechanism 5, and the first driving mechanism 5 is used to drive the storage table 3 to rise and fall to achieve the positioning of the storage table 3 and the sample bottle.

[0078] The first driving mechanism 5 may be an existing linear driving mechanism. Figure 1 In this embodiment, the first driving mechanism 5 can select the existing ball screw linear module composed of guide rails, ball screws, motors, slides and other components. Its specific structure can be Figure 1 The structure shown in FIG. 1 is for illustrative purposes only and will not be described in detail here.

[0079] See also Figure 1 In this embodiment, the storage platform 3 is a rectangular plate structure, but is not limited thereto. For example, in other embodiments, the storage platform 3 may also be circular, elliptical, or other regular or irregular shapes. Figure 2 and Figure 4 The storage table 3 is provided with a plurality of film storage slots 31, the number and position of the film storage slots 31 are adapted to the number and placement positions of the sample bottles on the tray 2, for example, see Figure 2 The sample bottles in the tray 2 are arranged in a 5×5 square matrix, and correspondingly, the film storage slots 31 on the storage table 3 are also arranged in a 5×5 square matrix, so that when the storage table 3 and the tray 2 are facing each other up and down, each film storage slot 31 is exactly opposite to each sample bottle and each push rod 42, and the length of the push rod 42 is greater than the depth of the film storage slot 31.

[0080] See also Figure 4 and Figure 5 In this embodiment, each film storage slot 31 includes a storage segment 311 and a positioning segment 312, and the storage segment 311 and the positioning segment 312 are arranged from top to bottom. The inner diameter of the storage segment 311 is the same as the inner diameter of the sample bottle, and multiple filter discs 9 are stored in the storage segment 311, and the bottom layer of filter discs 9 is flush with the bottom surface of the storage segment 311; the inner diameter of the positioning segment 312 is the same as the outer diameter of the mouth of the sample bottle, that is, the inner diameter of the positioning segment 312 is larger than the inner diameter of the storage segment 311, so that a step structure is formed between the positioning segment 312 and the storage segment 311.

[0081] Based on the above structural design, when the storage table 3 and the tray 2 are facing each other up and down, driving the storage table 3 to move downward can make the positioning section 312 at the bottom of the film storage slot 31 cover the bottle mouth of the sample bottle, and make the step between the storage segment 311 and the positioning section 312 abut the top of the sample bottle. In this way, not only can the accurate positioning of the sample bottle and the film storage slot 31 be ensured, providing a basis for the precise pushing of the filter 9, but also when the step between the storage segment 311 and the positioning section 312 abuts the top of the sample bottle, the inner wall of the storage segment 311 also just connects with the inner wall of the bottle mouth of the sample bottle, so that the filter 9 can be smoothly and unobstructedly pushed into the sample bottle, which has better operability and stronger reliability.

[0082] Further, in this embodiment, the height of the storage segment 311 should be sufficient to accommodate a predetermined number of filter discs 9, for example, see Figure 5, the storage segment 311 needs to store eight filter discs 9, so the height of the storage segment 311 should be at least 8 times or more of the thickness of the filter disc 9; and the height of the positioning segment 312 only needs to be sufficient to cover the mouth of the sample bottle, and there is no need to set the height too large, for example, the height of the positioning segment 312 can be 2-5mm. Such a setting can ensure the precise positioning of the positioning segment 312 and the sample bottle, and can also achieve the rapid matching and separation of the positioning segment 312 and the sample bottle.

[0083] Furthermore, in the present embodiment, the diameter of the storage segment 311 is slightly smaller than the diameter of the filter disc 9. For example, the diameter of the storage segment 311 is 0.5 mm smaller than the diameter of the filter disc 9. In this way, the filter disc 9 can be stuck in the storage segment 311 in an oversaturated manner, preventing the filter disc 9 from sliding freely in the storage segment 311, thereby ensuring the placement stability of the filter disc 9 and facilitating the pushing and loading of the filter discs 9 one by one.

[0084] See also Figure 6 In this embodiment, the filter disc 9 includes a support ring 92 and a filter membrane 91 disposed in the inner hole of the support ring 92. The outer diameter of the support ring 92 is 0.5 mm larger than the inner diameter of the storage segment 311. The support ring 92 can be made of a material that is both tough and strong, such as plastic. In this way, the filter disc 9 can be ensured to have a certain deformation ability so that the filter disc 9 can be supersaturatedly inserted into the storage segment 311 and the sample bottle, and the shape of the filter disc 9 can be kept unchanged when it is pushed, so as to realize the feeding of the filter discs 9 in the storage segment 311 one by one, and the filter disc 9 in the sample bottle can be made to fall close to the inner wall of the sample bottle, thereby ensuring the filtering effect of the filter disc 9.

[0085] Furthermore, in this embodiment, the thickness of the support ring 92 is greater than the thickness of the filter membrane 91. For example, if the thickness of the filter membrane 91 is 0.5 mm, the thickness of the support ring 92 may be 2 mm, 2.5 mm, etc. In this way, the support ring 92 is used to increase the overall thickness of the filter disc 9, so as to increase the operability of the filter disc 9 when it is transferred from the storage segment 311 to the sample bottle, and it is more conducive to realizing the pushing and loading of the filter discs 9 one by one.

[0086] Further, see Figure 7 In this embodiment, the sample bottle has a vertical section and a tapered section distributed from top to bottom, the inner diameter of the vertical section is equal to the inner diameter of the storage section 311, and the inner diameter of the tapered section gradually decreases from top to bottom. In this way, the vertical section can ensure that the inner diameter of the upper part of the sample bottle remains consistent, so that the filter 9 can move downward close to the inner wall of the vertical section to ensure the filtering effect of the filter 9, and the tapered section can be used as a limiting structure. Since the inner diameter of the tapered section gradually decreases, when the filter 9 descends to the tapered section, the tapered section can limit the descent of the filter 9 to ensure that the position of the filter 9 in each sample bottle is consistent.

[0087] See also Figure 1 and Figure 2In this embodiment, the third driving mechanism 7 is disposed on the second supporting plate 82, and the first driving mechanism 5 is disposed as a whole on the third driving mechanism 7. The third driving mechanism 7 drives the first driving mechanism 5 to move horizontally as a whole, thereby realizing the horizontal movement of the storage table 3.

[0088] Specifically, in this embodiment, the third driving mechanism 7 may be a linear driving mechanism horizontally arranged on the second supporting plate 82, for example, see Figure 1 The existing synchronous belt linear module composed of a motor, a synchronous belt (not shown in the figure), a pulley and a guide rail can be selected. The specific structure can be Figure 1 Of course, in other embodiments, a ball screw linear module can also be used.

[0089] The use of the filtering device based on the above-mentioned fermented grains sample includes the following steps:

[0090] S10, such as Figure 2 As shown, the tray 2 loaded with multiple sample bottles is first placed in the first position, directly below the lifting plate 41, with each push rod 42 facing each sample bottle;

[0091] S20, after the tray 2 is placed in place, the third driving mechanism 7 is started to drive the storage table 3 to move horizontally from directly above the second position to directly above the first position, facing the tray 2 vertically, so that each film storage slot 31 faces each sample bottle, such as Figure 1 As shown;

[0092] S30, start the first driving mechanism 5 to drive the storage table 3 to descend until the step between the positioning segment 312 and the storage segment 311 abuts against the top of the sample bottle. At this time, the positioning segment 312 covers the bottle mouth of the sample bottle, and the inner wall of the storage segment 311 is connected with the inner wall of the bottle mouth of the sample bottle;

[0093] S40, after the storage table 3 moves to the right position, the second driving mechanism 6 is started to drive the lifting plate 41 to move downward, driving the push rod 42 downward, and the push rod 42 continues to descend by a thickness of the filter 9 after contacting the filter 9 in the storage slot 31, pushing the filter 9 at the bottom layer away from the storage segment 311 and into the sample bottle, while the filter 9 at the upper layer is just flush with the bottom surface of the storage segment 311, and then the second driving mechanism 6 drives the lifting plate 41 and the push rod 42 to rise and reset;

[0094] S40, after the push rod 42 is reset, the first driving mechanism 5 is started again to drive the storage table 3 to rise and reset. At this time, the filter disc 9 at the bottom layer remains in the sample bottle, and the remaining filter discs 9 rise together with the storage table 3. Then the third driving mechanism 7 drives the storage table 3 to reset horizontally to the second position, so that the storage table 3 is moved away from the top of the tray 2. Figure 2 As shown;

[0095] S50, after the storage table 3 is reset, the second driving mechanism 6 is started again, and the second driving mechanism 6 drives the lifting plate 41 to move downward, driving the push rod 42 downward, and the push rod 42 pushes the filter 9 in the sample bottle from the bottle mouth position downward to the lower part of the sample bottle. During the downward movement of the filter 9, the filter 9 pushes the solid matter in the sample solution downward, so that the fixed matter is always located below the filter 9, and the liquid part passes through the filter 9 and is located above the filter 9, completing the solid-liquid separation and realizing the filtration of the sample solution. The supernatant above the filter 9 is the target liquid, and then the second driving mechanism 6 drives the lifting plate 41 and the push rod 42 to rise and reset.

[0096] In the above filtration method, the position of the filter will change as the steps proceed. The specific change process can be found in Figure 7 .

[0097] In step S30, since the number of filter discs 9 in the film storage slot 31 will gradually decrease, the descending height of the push rod 42 when pushing the filter disc 9 to load will increase progressively. For example, when the film storage slot 31 is full of filters, the distance between the lower end of the push rod 42 and the topmost filter disc 9 is L, then when the filter disc is pushed for the first time, the descending height of the push rod 42 is L+t (thickness of the filter disc 9), and when the filter disc is pushed for the second time, the descending height of the push rod 42 is L+2t, and so on. Each time the filter disc 9 is pushed for loading, the descending height of the next push rod 42 will increase by t. In this way, by performing programmed control on the second drive mechanism 6, automatic loading of the filter disc 9 can be achieved, and the operability is good.

[0098] Through this filtration method, automatic filtration of the sample solution can be achieved in the sample bottle, which can reduce labor input and greatly improve detection efficiency. In addition, there is no need to transfer the sample solution, the operation is simple, and changes in the sample solution during the transfer process can be avoided, ensuring accurate inspection results.

[0099] Example 2

[0100] See also Figure 8 and Fig. 9 This embodiment provides a filtering device for a wine mash sample, which differs from Embodiment 1 only in that, in this embodiment, the third driving mechanism 7 is arranged on the first supporting plate 81, and the second driving mechanism 6 is arranged as a whole on the third driving mechanism 7, and the third driving mechanism 7 drives the second driving mechanism 6 to move horizontally as a whole, thereby realizing the horizontal movement of the pushing component 4.

[0101] The filtering device provided in this embodiment comprises the following steps when used:

[0103] S20, after the tray 2 is placed in place, the first driving mechanism 5 is started to drive the storage table 3 to descend until the step between the positioning segment 312 and the storage segment 311 abuts against the top of the sample bottle. At this time, the positioning segment 312 covers the bottle mouth of the sample bottle, and the inner wall of the storage segment 311 is connected with the inner wall of the bottle mouth of the sample bottle;

[0104] S30, start the third driving mechanism 7, drive the lifting plate 41 to move horizontally from directly above the first position to directly above the second position, and directly face the storage table 3, so that each push rod 42 directly faces each film storage slot 31. Figure 8 As shown;

[0105] S30, start the second driving mechanism 6, drive the lifting plate 41 to move downward, drive the push rod 42 downward, and after the push rod 42 contacts the filter 9 in the storage slot 31, it continues to descend by a height of the thickness of the filter 9, pushes the bottom filter 9 away from the storage segment 311 and into the sample bottle, and the filter 9 on the upper layer is just flush with the bottom surface of the storage segment 311, and then the second driving mechanism 6 drives the lifting plate 41 and the push rod 42 to rise and reset;

[0106] S40, after the push rod 42 is reset, the first driving mechanism 5 is started again to drive the storage table 3 to rise and reset. At this time, the filter disc 9 at the bottom layer remains in the sample bottle, and the remaining filter discs 9 rise together with the storage table 3. Then, the third driving mechanism 7 drives the storage table 3 to reset horizontally to the second position, so that the storage table 3 is moved away from the top of the tray 2.

[0107] S50, after the storage table 3 is reset, the conveyor belt mechanism is started to transport the tray 2 to the first position, and then the third driving mechanism 7 is started to drive the lifting plate 41 to reset horizontally to just above the first position, and to face the tray 2 up and down, so that each push rod 42 faces each sample bottle, and then the second driving mechanism 6 is started again, and the second driving mechanism 6 drives the lifting plate 41 to move downward, driving the push rod 42 downward, and the push rod 42 pushes the filter disc 9 in the sample bottle from the bottle mouth position downward to the lower part of the sample bottle. During the downward movement of the filter disc 9, the filter disc 9 pushes the solid matter in the sample solution downward, so that the fixed matter is always located below the filter disc 9, and the liquid part passes through the filter disc 9 and is located above the filter disc 9, completing the solid-liquid separation and realizing the filtration of the sample solution. The supernatant above the filter disc 9 is the target liquid, and then the second driving mechanism 6 drives the lifting plate 41 and the push rod 42 to rise and reset, as shown in FIG. Fig. 9 shown.

[0110] See also Fig.10 The loading unit 10 includes a tray 2, and a plurality of slots for loading sample bottles are arranged on the tray 2. Specifically, the tray 2 is rectangular, and the slots on the tray 2 are arranged in a 5×5 square matrix, so that each sample bottle can be regularly placed on the tray 2, which provides convenience for subsequent operations such as adding liquid, screwing the cap, and taking liquid from each sample bottle.

[0111] Furthermore, in this embodiment, the number of the trays 2 can be set to be multiple, so as to realize continuous automated pre-treatment of the sample solution.

[0112] The conveying unit 20 is used to convey the tray 2. Fig.10 In this embodiment, the conveying unit 20 is a conveyor belt mechanism, and a first operating position, a second operating position, a third operating position and a fourth operating position are sequentially provided along the conveying direction of the conveyor belt mechanism. In this way, when the tray 2 is placed on the conveyor belt mechanism, the conveyor belt mechanism can drive the tray 2 to pass through the first operating position, the second operating position, the third operating position and the fourth operating position in sequence along the conveying direction to complete operations such as adding liquid, filtering, and taking liquid.

[0113] The liquid adding unit 30 is disposed at the first operating position, and is used to add sample solution to the sample bottle located at the first operating position. Fig.11 The liquid adding unit 30 includes a liquid storage container 301, a liquid adding device 302 and a liquid adding drive device 303. The liquid storage container 301 is used to store the sample solution, and it can be a container such as a liquid storage tank or a liquid storage barrel. The liquid adding device 302 is connected to the liquid storage container 301 through a hose and is equipped with a power device such as a pump. The liquid adding device 302 can specifically use an existing multi-channel pipette. Specifically, corresponding to the sample bottles arranged in a 5×5 square matrix, the liquid adding device 302 can use a five-channel pipette, which can realize the one-time addition of liquid to 5 sample bottles, thereby improving the liquid adding efficiency. The liquid adding drive device 303 can use an existing biaxial manipulator. The liquid adding device 302 is arranged at the execution end of the biaxial manipulator. The biaxial manipulator has two driving directions, one is the lifting drive, and the other is along the horizontal direction perpendicular to the conveyor belt mechanism.

[0114] The working principle of the liquid adding unit 30 is as follows: when the tray 2 is transported to the first operating position, the sample solution in the liquid storage container 301 is pumped into the liquid adding device 302, and then the liquid adding drive device 303 drives the liquid adding device 302 to move horizontally to just above the sample bottles in the first row, and then drives the liquid adding device 302 to descend and extend into the sample bottles, and then the liquid adding device 302 injects the sample solution into the sample bottles, and then the liquid adding drive device 303 drives the liquid adding device 302 to rise and reset, and then repeat the above steps until all the sample bottles in the tray 2 are added with the sample solution.

[0115] The cap screwing unit 40 is disposed at the second operating position, and is used to screw open or tighten the cap of the sample bottle at the second operating position. Fig.12 The capping unit 40 includes a capping device 401 and a capping driving mechanism 402.

The capping driving mechanism 402 can be an existing multi-axis manipulator, and the capping device 401 is arranged at the execution end of the multi-axis manipulator.

[0116] The working principle of the capping unit 40 is as follows: when the tray 2 is transported to the second operating position, the capping drive mechanism 402 drives the capping device 401 to move to the sample bottles in the first row, and then the capping device 401 unscrews or tightens the bottle caps, and so on, until the caps of the sample bottles in the five rows are all unscrewed or tightened. In actual application, the capping device 401 tightens the caps of the sample bottles that have not been shaken, and unscrews the caps of the sample bottles that have been shaken.

[0117] The oscillation unit 50 is disposed on one side of the second operating position to oscillate the sample bottle after the bottle cap is tightened to ensure that the sample solution is uniform. Fig.12 The oscillation unit 50 includes an oscillator 501 and a transfer mechanism 502, wherein the oscillator 501 can be selected from an existing automatic oscillator, and the transfer mechanism 502 can be selected from a Fig.11 The two push cylinders shown push the tray 2 from the second operating position to the oscillator 501 or from the oscillator 501 to the second operating position. In this embodiment, the transfer mechanism 502 can be preferably an existing grabbing manipulator, which is convenient for grabbing the sample bottles to the oscillator 501 one by one.

[0118] The working principle of the oscillation unit 50 is as follows: the sample bottle at the second operating position is grabbed to the oscillator 501 by the transfer mechanism 502, and the oscillator 501 oscillates the sample bottle. After the oscillation is completed, the transfer mechanism 502 puts the sample bottle back to the second operating position.

[0119] See also Fig.10The filtering unit 60 is arranged at the third operating position, and is used to filter the sample solution in the sample bottle located at the third operating position. It specifically adopts the wine mash sample filtering device provided in Example 1. Its structure and use principle can refer to the relevant description of Example 1, and will not be repeated here.

[0120] The liquid sampling unit 70 is disposed at the fourth operating position to sample the filtrate in the sample bottle at the fourth operating position. Fig.13 In this embodiment, the liquid taking unit 70 includes a liquid taking device 701 and a liquid taking drive device 702. The liquid taking device 701 can use the same five-channel pipette as the liquid adding device 302, and be equipped with a power device to absorb and discharge the solution. The liquid taking drive device 702 can use the same dual-axis manipulator with two driving directions of lifting and horizontal as the liquid adding drive device 303.

[0121] The operating principle of the liquid taking unit 70 is as follows: after the tray 2 is transported to the fourth operating position, the liquid taking drive device 702 drives the liquid taking device 701 to move horizontally to just above the first row of sample bottles, and then drives the liquid taking device 701 to descend and extend into the sample bottle, and the liquid taking device 701 draws the filtrate in the sample bottle, and then the liquid adding drive device 303 drives the liquid adding device 302 to rise and reset, and move horizontally to a receiving tube (not shown in the figure) for receiving the filtrate, and the filtrate is transferred to the receiving tube through the liquid taking device 701, and then the liquid adding drive device 303 drives the liquid adding device 302 to move horizontally to just above the sample bottles in the second horizontal row, and then repeats the liquid taking and discharging operations until the filtrate in all sample bottles is transferred.

[0122] In this embodiment, the mash sample pretreatment system also includes a controller, which is electrically connected to the conveying unit 20, the liquid adding unit 30, the capping unit 40, the oscillation unit 50, the filtering unit 60, and the liquid taking unit 70 to control the operation of each unit.

[0123] See also Fig.10 In this embodiment, a detector 80 for detecting the tray 2 is provided at each operating position, and the controller controls the start and stop of the conveyor belt according to the signal of the detector 80. For example, when the tray 2 is conveyed to the first operating position, the detector 80 at the first operating position detects the tray 2 and feeds back the signal to the controller, and the controller controls the conveying mechanism to stop, so that the tray 2 stops at the first operating position. Specifically, in this embodiment, the detector 80 can select an existing photoelectric sensor.

[0124] The pre-treatment system according to this embodiment comprises the following steps when used:

[0125] Bottling, placing tray 2 on the conveyor belt mechanism, and loading the sample bottles into tray 2;

[0126] Add liquid, the conveyor belt mechanism drives the tray 2 to be transported forward, when the detector 80 detects that the tray 2 is transported to the first operating position, the controller controls the conveyor belt mechanism to stop, performs the liquid adding operation, pumps the sample solution in the liquid storage container 301 into the liquid adding device 302, the liquid adding drive device 303 drives the liquid adding device 302 to move horizontally to just above the sample bottles in the first row, and then drives the liquid adding device 302 to descend and extend into the sample bottles, and then the liquid adding device 302 injects the sample solution into the sample bottles, and then the liquid adding drive device 303 drives the liquid adding device 302 to rise and reset, and then repeats the liquid adding steps until all the sample bottles in the tray 2 are added with the sample solution;

[0127] After the filling of the cap is completed, the controller controls the conveying drive mechanism to start, and drives the tray 2 to continue to be conveyed forward. When the detector 80 detects that the tray 2 is conveyed to the second operation position, the controller controls the conveyor belt mechanism to stop and perform the capping operation. The capping drive mechanism 402 first drives the capping device 401 to pick up the bottle cap, and then drives the capping device 401 to move to the sample bottles in the first row. The capping device 401 tightens the bottle cap on the sample bottles in the first row, and then the capping drive mechanism 402 drives the capping device 401 to reset, and then repeats the operations of picking up and capping until all the sample bottles are capped.

[0128] After the capping is completed, the oscillation operation is performed, and the sample bottles located at the second operation position are successively grabbed to the oscillator 501 by the transfer mechanism 502. After all the sample bottles are located on the oscillator 501, the oscillator 501 is started to oscillate the sample bottles. After the oscillation is completed, the transfer mechanism 502 puts the sample bottles back to the second operation position;

[0129] After the oscillation is completed, the capping operation is performed, the capping driving mechanism 402 drives the capping device 401 to move to the sample bottles in the first row, the capping device 401 unscrews the bottle caps on the sample bottles in the first row, and then the capping driving mechanism 402 drives the capping device 401 to move to the bottle cap placement position, puts the bottle caps down, and then the capping driving mechanism 402 drives the capping device 401 to reset, and then repeat the capping and capping operations until the bottle caps of all sample bottles are removed;

[0130] After the filtration and opening of the cover are completed, the controller controls the conveying drive mechanism to start, driving the tray 2 to continue to be conveyed forward. When the detector 80 detects that the tray 2 is conveyed to the third operating position, the controller controls the conveying belt mechanism to stop, performs the filtration operation, and starts the third driving mechanism 7, first by driving the storage table 3 to move horizontally from just above the second position to just above the first position, facing the tray 2 up and down, so that each storage slot 31 faces each sample bottle, and then starts the first driving mechanism 5 to drive the storage table 3 to descend until the positioning section 31 2 and the step between the storage segment 311 and the top of the sample bottle. At this time, the positioning segment 312 covers the bottle mouth of the sample bottle, and the inner wall of the storage segment 311 is connected with the inner wall of the bottle mouth of the sample bottle. After the storage table 3 moves to the right position, the second driving mechanism 6 is started to drive the lifting plate 41 to move downward, driving the push rod 42 downward. After the push rod 42 contacts the filter 9 in the storage slot 31, it continues to descend by a height of the thickness of the filter 9, pushing the bottom filter 9 away from the storage segment 311 and into the sample bottle, while the filter 9 of the upper layer just touches the storage slot. After the bottom surface of the section 311 is flush, the second driving mechanism 6 drives the lifting plate 41 and the push rod 42 to rise and reset; after the push rod 42 is reset, the first driving mechanism 5 is started again to drive the storage table 3 to rise and reset. At this time, the filter disc 9 at the bottom layer remains in the sample bottle, and the remaining filter discs 9 rise together with the storage table 3, and then the third driving mechanism 7 drives the storage table 3 to reset horizontally to the second position, so that the storage table 3 is removed from the top of the tray 2; after the storage table 3 is reset, the second driving mechanism 6 is started again, and the second driving mechanism 6 drives the lifting plate 41 to move downward, driving the push rod 42 downward, and the push rod 42 pushes the filter disc 9 in the sample bottle from the bottle mouth position downward to the lower part of the sample bottle. During the downward movement of the filter disc 9, the filter disc 9 pushes the solid matter in the sample solution downward, so that the fixed matter is always located below the filter disc 9, and the liquid part passes through the filter disc 9 and is located above the filter disc 9, completing the solid-liquid separation and realizing the filtration of the sample solution. The supernatant above the filter disc 9 is the target liquid, and then the second driving mechanism 6 drives the lifting plate 41 and the push rod 42 to rise and reset;

[0131] After the liquid is taken and the filtration is completed, the controller controls the conveying driving mechanism to start and drive the tray 2 to continue to be transported forward. When the detector 80 detects that the tray 2 is transported to the fourth operating position, the controller controls the conveyor belt mechanism to stop and perform the liquid taking operation. The liquid taking drive device 702 drives the liquid taking device 701 to move horizontally to the top of the first row of sample bottles, and then drives the liquid taking device 701 to descend and extend into the sample bottle. The liquid taking device 701 draws the filtrate from the upper layer of the sample bottle, and then the liquid adding drive device 303 drives the liquid adding device 302 to rise and reset, and move horizontally to the receiving tube for receiving the filtrate, and the filtrate is transferred to the receiving tube through the liquid taking device 701. Then the liquid adding drive device 303 drives the liquid adding device 302 to move horizontally to the top of the second horizontal row of sample bottles, and then repeats the liquid taking and discharging operations until the filtrate in all sample bottles is transferred.
