Description

Technical Field

[0001] The invention belongs to the technical field of material separation, and in particular relates to a modular adjustable rapeseed cleaning cyclone separation test device. Background Art

[0002] Rapeseed cleaning is a key process in rapeseed combine harvesting. It targets the threshed and separated rapeseed residue, primarily consisting of seeds, short stems, husks, and light debris. Cyclone cleaning is a pure airflow cleaning method, with the cyclone separation drum and fan as the main components. The fan generates negative pressure within the cyclone separation drum, utilizing the difference in suspension speed between the seeds and debris to draw out the debris and separate them. The cyclone separation cleaning device has a simple structure and is suitable for widespread use in rapeseed combine harvesters.

[0003] During the cleaning process, the cyclone speed inside the cyclone separation cylinder will affect the cleaning effect of the discharged material. If the cyclone speed is too fast, most of the impurities in the discharged material will be suspended along with the grains. If the cyclone speed is too slow, the grains in the discharged material will be directly discharged, thereby reducing the separation efficiency of rapeseed cleaning.

[0004] Therefore, it is necessary to invent a modular adjustable rapeseed cleaning cyclone separation test device to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example 1:

[0029] The present invention provides a modular adjustable rapeseed cleaning cyclone separation test device, such as Figures 1 to 6As shown, the cyclone separator 1 comprises a conveying component, a cyclone separator 1, an extraction component 2, a connecting pipe 3, an air volume adjustment component, and a telescopic component. The cyclone separator 1 is configured as a cylindrical structure. The first outlet 101 at the top of the cyclone separator 1 is plugged into one end of the connecting pipe 3, and the other end of the connecting pipe 3 is connected to the input end of the extraction component 2. The extraction component 2 is configured as a fan, and the fan motor provides driving force for the extraction component 2. The conveying component transports the material into the cyclone separator 1. When the fan motor is working, the output end of the fan motor drives the extraction component 2 to work. The extraction component 2 uses the connecting pipe 3 to generate a rotating airflow inside the cyclone separator 1 and the corrugated portion 5. Under the action of the rotating airflow, the seeds, broken stems, chaff, etc. in the material have different movement trajectories according to their density. Under the action of the rotating airflow, the seeds with higher density spiral downward along the wall of the cyclone separator 1 to the second outlet 102 of the cyclone separator 1 under the action of centrifugal force, and are discharged into the collection component through the second outlet 102. Under the action of radial airflow in the cyclone separator 1, light debris with lower density spirals upward in the center of the cyclone separator 1 and is discharged into the debris suction bag through the connecting pipe 3 and the extraction component 2. The debris suction bag collects the material discharged by the extraction component 2.

[0030] The air volume inside the connecting tube 3 was adjusted using the air volume adjustment component, and the effect of the rotating air flow velocity inside the cyclone 1 on the material separation experiment was determined. Since the bellows 5 was mounted on the top of the cyclone 1 via a locking component, the bellows 5 was configured as a bellows, with the interior of the bellows 5 configured as an extension of the top of the cyclone 1. The length of the bellows 5 was varied using a telescopic component, and the effect of the length of the bellows 5 on the material separation experiment was measured.

[0031] In order to transport the material, the material is transported to the inside of the cyclone separator 1 through the transport component. Figure 1 and Figure 2 In the embodiment, the conveying components include: an auger 16, a silo 17, a winnowing device 18, an incision pipe 19 and a driving component. The feed port of the silo 17 is vertically upward, the bottom of the silo 17 is connected to the top of the auger 16, one end of the auger 16 is connected to the winnowing device 18, the output end of the winnowing device 18 is connected to the cyclone separation drum 1 through the incision pipe 19, and the power end of the winnowing device 18 is connected to the rotating part of the auger 16. The rotating part of the auger 16 is connected to the output end of the driving component through a belt drive, and the driving component is set as a winnowing device motor 181. The material is passed into the interior of the auger 16 through the feed port of the silo 17, and the driving component works. The output end of the driving component uses a belt to rotate the rotating part of the auger 16. The rotating part of the auger 16 feeds the material into the winnowing device 18. The material is thrown into the cyclone separation drum 1 along the incision pipe 19 by the winnowing device 18, thereby realizing the material transportation.

[0032] Specifically, to ensure that the parameters of the material separation test are controllable, the fan motor and drive components are controlled by different frequency regulators. The fan motor and the winnowing device motor 181 are both connected to the frequency regulator, and the frequency regulator is used to adjust the frequency to control the speed of the fan motor and the winnowing device motor 181. For example, the fan motor and the winnowing device motor 181 both use a three-phase asynchronous motor model Y090S-4, with a rated speed of 1400 r / min and a rated power of 1.1 kW. The speed is adjusted by the frequency regulator, and the speed range is 0-2000 r / min. Both the speed and power meet the requirements of the test. To make speed regulation convenient and direct, the transmission ratio of the two chains is set to 1, and the chain model used is 10A.

[0033] In order to experiment with material separation, the air volume inside the connecting pipe 3 is changed by an air volume adjusting component, and the air volume adjusting component includes: an air volume baffle 10, an adjusting shaft 11, a first rotating plate 12 and a second rotating plate 13. The air volume baffle 10 is set as a circular plate, and the outer side surface of the horizontally set air volume baffle 10 fits with the inside of the connecting pipe 3, and the horizontal air volume baffle 10 completely blocks the connecting pipe 3. The adjusting shaft 11 is installed at the center of the air volume baffle 10, and both ends of the adjusting shaft 11 pass through the connecting pipe 3. The first rotating plate 12 and the second rotating plate 13 are connected to both ends of the adjusting shaft 11 respectively, and the inner sides of the first rotating plate 12 and the second rotating plate 13 are both fitted with the outer side surface of the circumference of the connecting pipe 3.

[0034] In this embodiment, the air volume baffle 10 is rotated within the connecting pipe 3 via the adjustment shaft 11. The rotating air volume baffle 10 tilts within the connecting pipe 3, and the rotation of the air volume baffle 10 adjusts the air volume within the connecting pipe 3. Specifically, as the air volume baffle 10 rotates from a horizontal position to a vertical position, the blocking effect of the air volume baffle 10 on the connecting pipe 3 gradually decreases, while the air volume flowing within the connecting pipe 3 gradually increases. When the air volume baffle 10 is in the vertical position, the air volume flowing within the connecting pipe 3 reaches its maximum.

[0035] Annular grooves are provided on the circumferential outer side surfaces of the first rotating plate 12 and the second rotating plate 13, and convex strips 403 corresponding to the annular grooves are provided on the surface of the cross bar 402. The rotating first rotating plate 12 rotates on the surface of the convex strips 403 using the annular grooves. A blocking strip 121 corresponding to the convex strips 403 is provided inside the annular groove of the first rotating plate 12. When the side surface of the blocking strip 121 is in contact with the convex strip 403, the air volume baffle 10 is in a vertical state inside the connecting pipe 3.

[0036] By adjusting the rotation of the shaft 11, the rotation state of the air volume baffle 10 inside the connecting pipe 3 is changed, which facilitates real-time change of the flow air volume inside the connecting pipe 3, and then changes the rotating air flow speed inside the cyclone separation cylinder 1. The influence of the rotating air flow speed on the material separation experiment can be obtained. By rotating the air volume baffle 10 to change the rotating air flow speed, the grains in the material are recovered through the connecting pipe 3, thereby improving the separation efficiency of the material.

[0037] For example, to determine the height of the cyclone separation drum 1, the test process is as follows:

[0038] According to the feeding amount q of the barn 17 and the grass-grain ratio λ of the material, the feeding amount of grain and grass can be obtained:

[0039] in,

[0040] The rapeseed products (seeds, broken stems, chaff, etc.) after the threshing component are sent to the cyclone separator 1 through the conveying component. After the cyclone separator 1 is cleaned, clean grains are obtained. In the threshing component, 70% of the impurities have been discharged, and only about 30% of the impurities are mixed in the grains and need to be cleaned. The material taken away by the extraction component 2 is: q 杂 =30%×q 草 .

[0041] According to the impurity specific gravity r, the amount of material sucked away by the extraction component 2 is: Q 杂 =q 杂 / r.

[0042] According to the empirical data of air flow cleaning design, the required air volume Q is generally 1000 times the flow rate of the separated flow, so: Q = 1000 × Q 杂 .

[0043] From the principle of the cyclone separator 1, it can be seen that the cyclone separator 1 obviously divides the air flow velocity into a high-speed central area and a low-speed surrounding area. According to the cleaning requirements, the diameter D of the cyclone separator 1 can be obtained as follows:

[0044]

[0045] Wherein, D1 is the inner diameter of the air outlet (i.e. the diameter of the connecting pipe 3) (m);

[0046] vinner - air velocity in the axial high-speed zone (m / s);

[0047] vouter—air velocity in the low-speed zone of the cyclone separation cylinder wall (m / s);

[0048] During the design, the diameter D1 of the connecting pipe 3 is selected; according to the cleaning principle of the cyclone separation cylinder 1, the low-speed airflow near the wall of the cyclone separation cylinder 1 is mainly used to separate light debris such as husks. According to the suspension speed of the debris, v can be selected. 外 The central high-speed zone is mainly used to separate the grains. According to the floating speed of the grains, v is selected. 内 , substituting the above parameters into the above formula, we can get D.

[0049] The top of the cyclone separation drum 1 is configured as a cone, wherein the adjustable range of the cone angle a is generally between 30° and 45°.

[0050] Based on the rapeseed thresher, the rapeseed feed rate of the cyclone separation drum 1 is set to q = 0.35 kg / s. According to relevant data, the grass-to-grain ratio of rapeseed is λ = 2.99. According to the above formulas, we can get:

[0051] q 谷 =0.088;q 草 =0.262;q 杂 =0.0786; Q 杂 =0.000393(m 3 / s); Q = 0.393 (m 3 / s).

[0052] Select the diameter D1 of the connecting pipe 3 = 120mm, and select v according to the suspension speed of the rapeseed to remove debris. 外 =4m / s, select v according to the suspension speed of rapeseed grains 内 =6m / s, substitute the above parameters into the formula:

[0053]

[0054] Select D = 320mm, select a = 45°, to prevent the rapeseed grains from being stationary on the lower cone surface, select the cone bottom angle b = 60°, select c = d = 100mm

[0055] If the height H of the cyclone separation drum 1 is too small, it will lead to insufficient separation space, while if it is too large, it will be unfavorable for the discharge of impurities. Therefore, H is set to 300 mm.

[0056] In order to conduct experiments on material separation, the length of the corrugated portion 5 can also be changed by the telescopic component. Figures 4 to 6In the embodiment, the telescopic component includes: a first slide 4, a corrugated portion 5, a snap slide 6 and a locking component. The two snap slides 6 are arranged opposite to each other, and the first slide 4 is between the two snap slides 6. In the process of the first slide 4 sliding between the two snap slides 6, the corrugated portion 5 is telescoped by the connecting component. The connecting component includes a connecting bar 401 and a cross bar 402. The connecting bar 401 is vertically arranged. The connecting bar 401 vertically passes through the first slide 4, and the top and bottom surfaces of the first slide 4 are spirally sleeved with a fastening sleeve. The fastening sleeve is used to fix the first slide 4 and the connecting bar 401. The top end of the connecting bar 401 is sleeved on the outer end of the cross bar 402, and the inner end of the cross bar 402 is connected to the outer circumferential surface of the connecting pipe 3, and the outer circumferential surface of the first rotating plate 12 is in contact with the outer circumferential surface of the cross bar 402.

[0057] In an embodiment, when the first slide 4 moves up and down between the two snap slides 6, the moving first slide 4 uses the connecting bar 401 to make the cross bar 402 drive the connecting tube 3 to move up and down, and the connecting tube 3 that moves downward squeezes the corrugated part 5, and the connecting tube 3 that moves upward stretches the corrugated part 5.

[0058] In order to limit the first slide plate 4, the first slide plate 4 is locked by a snap-fit ​​component, which includes: an insertion rod 7, a slot 8 and a first elastic member 9. The first elastic member 9 is configured as a spring, and a plurality of slots 8 arranged in parallel are provided on the inner wall of the snap-fit ​​slide 6. The insertion rod 7 passes through the through slot at the top of the first slide plate 4. The insertion rod 7 is horizontally arranged, and a slider 701 is provided inside the through slot. The slider 701 is fixed in the middle of the insertion rod 7, and the first elastic member 9 is sleeved on the inner side of the insertion rod 7. One end of the first elastic member 9 is connected to the slider 701, and the other end of the first elastic member 9 is connected to the inner wall of the through slot. The elastic force of the first elastic member 9 causes the outer end of the insertion rod 7 to be snapped into the inside of the slot 8.

[0059] In this embodiment, when the first slide plate 4 slides up and down, the moving first slide plate 4 drives the insertion rod 7 to move up and down synchronously. Since the multiple slots 8 are arranged vertically in parallel, and the elastic force of the first elastic member 9 acts on the insertion rod 7, the first slide plate 4 that moves up and down causes the outer end of the insertion rod 7 to move up and down inside the multiple slots 8 until the outer end of the insertion rod 7 is locked in the slot 8. At this time, the first slide plate 4 is confined between the two locking slides 6.

[0060] In order to ensure that the connecting pipe 3 is always connected to the cyclone separation drum 1, the connecting pipe 3 is fixed to the outside of the first outlet 101 at the top of the cyclone separation drum 1 by a locking component. Figure 4 and Figure 6In the figure, the locking component includes: two semicircular rings 14 and a vertical rod 15, the bottom end of the vertical rod 15 is correspondingly inserted into the through hole on the top surface of the semicircular ring 14, the two semicircular rings 14 are arranged opposite to each other, the inner concave surface of the semicircular ring 14 fits with the outer circumferential surface of the connecting pipe 3, both ends of the semicircular ring 14 are fixed with side edges, and the bolt component passes through the side edges of the semicircular ring 14, the bolt component includes a screw and a nut, the screw passes through the sides of the two semicircular rings 14, and the spiral fit of the nut and the bolt makes the two semicircular rings 14 snap on the outer circumferential surface of the connecting pipe 3, so that the connecting pipe 3 is always sleeved on the first outlet 101 at the top of the cyclone separation cylinder 1 during the expansion and contraction of the corrugated portion 5.

[0061] In addition, during the lifting process of the connecting pipe 3, the top end of the vertical rod 15 is sleeved on the outer side of the annular groove of the second rotating plate 13 by means of the collar 151. The connecting pipe 3 that moves up and down uses the collar 151 to make the vertical rod 15 move up and down inside the through hole of the semicircular ring 14, so that the connecting pipe 3 always extends and contracts in the vertical direction. The collar 151 uses the second rotating plate 13 to limit the connecting pipe 3, preventing the connecting pipe 3 from moving horizontally at the top end of the connecting bar 401 by means of the cross bar 402, so that the corrugated portion 5 is always in a vertical state.

[0062] In order to collect the materials discharged from the cyclone separation drum 1, the materials discharged from the second outlet 102 are collected by the collecting component. Figures 2 to 4 In the embodiment, the collecting component includes: a collecting bin 20, two slide bars 21 and a driving member, the driving member is set as a second elastic member 23, the second elastic member 23 is set as a spring, an arc plate 26 is set on the top of the collecting bin 20, and a connecting port is opened on the top surface of the collecting bin 20, the two slide bars 21 are horizontally installed inside the outer frame 22, and a slide groove is set in the center of the slide bar 21. At this time, the outer end of the second slide plate 24 slides inside the slide groove, and an inner rod 25 is set inside the slide groove. The sliding second slide plate 24 moves on the surface of the inner rod 25, and the second elastic member 23 is sleeved on the surface of the inner rod 25. One end of the second elastic member 23 is connected to the second slide plate 24, and the other end of the second elastic member 23 is connected to the outer frame 22. On the inner wall of the chute, the collecting bin 20 is located between the two slide bars 21, and the collecting bin 20 uses the second slide plate 24 to squeeze the second elastic member 23 on the surface of the inner rod 25 during the inward movement. The inward-moving collecting bin 20 drives the arc plate 26 to approach the second outlet 102 at the bottom of the cyclone separation cylinder 1 until the inner concave surface of the arc plate 26 fits with the outer circumferential surface of the second outlet 102, and the bottom end of the second outlet 102 corresponds to the connecting port on the top surface of the collecting bin 20. Under the action of centrifugal force, the grains with higher density spirally move downward along the wall of the cyclone separation cylinder 1 to the second outlet 102 of the cyclone separation cylinder 1, and are discharged into the interior of the collecting bin 20 through the second outlet 102 and the connecting port.

[0063] Example 2:

[0064] exist Figure 7In order to pass materials into the cyclone separator 1, an incision pipe 19 is installed on both sides of the cyclone separator 1, and the input end of the incision pipe 19 is connected to the output end of the winnowing device 18. Through the throwing action of the winnowing device 18, the materials enter the cyclone separator 1 simultaneously along the two incision pipes 19. The output end of the incision pipe 19 is connected to an interface movable baffle 191, and the surface of the cyclone separator 1 is provided with a side groove corresponding to the interface movable baffle 191. The interface movable baffle 191 can move up and down inside the side groove. The movement of the interface movable baffle 191 drives the movement of the output port of the incision pipe 19. The movement of the output port of the incision pipe 19 changes the height at which the materials enter the cyclone separator 1, and explores the influence of the material entry height on the screening effect.

[0065] After the material enters the cyclone separation cylinder 1, the extraction component 2 uses the connecting pipe 3 to generate a rotating airflow inside the cyclone separation cylinder 1. Under the action of the rotating airflow, the seeds, broken stems, chaff, etc. in the material have different movement trajectories according to their density. Under the action of the rotating airflow, the seeds with higher density spiral downward along the wall of the cyclone separation cylinder 1 to the second outlet 102 of the cyclone separation cylinder 1 under the action of centrifugal force, and are discharged into the interior of the collecting component through the second outlet 102. The light debris with lower density spirals upward in the center of the cyclone separation cylinder 1 and is discharged into the debris suction bag through the connecting pipe 3 and the extraction component 2.

[0066] Example 3:

[0067] exist Figure 8 In the figure, the top and bottom of the cyclone separation cylinder 1 are both provided with cone parts, the top cone part is connected to the first outlet 101, and the bottom cone part is connected to the second outlet 102. The two cone parts are arranged opposite to each other. After the material enters the cyclone separation cylinder 1, the extraction component 2 uses the connecting pipe 3 to generate a rotating airflow inside the cyclone separation cylinder 1. Under the action of the rotating airflow, the light debris with lower density spirals upward in the center of the cyclone separation cylinder 1 and is discharged into the debris suction bag through the connecting pipe 3 and the extraction component 2.

[0068] Among them, the inclination angle of the cone is set to X, and X can be set to 30°, 45° and 60°. By changing the inclination angle of the cone, whether the inclination angle of the cone affects the material cleaning of the cyclone separation drum 1 is explored.

[0069] Working principle of the present invention:

[0070] Reference Figures 1 to 6 As shown, the end of the connecting pipe 3 is sleeved on the outer side of the first outlet 101, and the two semicircular rings 14 are arranged opposite to each other. The inner concave surface of the semicircular ring 14 fits with the outer circumferential surface of the connecting pipe 3, and the spiral fit of the cap and the bolt makes the two semicircular rings 14 snap on the outer circumferential surface of the connecting pipe 3.

[0071] The material is passed into the interior of the auger 16 through the feed port of the barn 17, and the driving component works. The output end of the driving component uses a belt to rotate the rotating part of the auger 16, and the rotating part of the auger 16 sends the material into the winnowing device 18. The throwing action of the winnowing device 18 sends the material along the cutting pipe 19 into the cyclone separation cylinder 1, thereby realizing the transportation of the material.

[0072] The fan motor is working, and the output end of the fan motor drives the extraction component 2 to work. The extraction component 2 uses the connecting pipe 3 to generate a rotating airflow inside the cyclone separation cylinder 1 and the corrugated part 5. Under the action of the rotating airflow, the seeds, broken stems, chaff, etc. in the material have different movement trajectories according to their density. Under the action of the rotating airflow, the seeds with higher density spiral downward along the wall of the cyclone separation cylinder 1 to the second outlet 102 of the cyclone separation cylinder 1, and are discharged into the interior of the collection component through the second outlet 102. Under the action of the radial airflow in the cyclone separation cylinder 1, the light debris with lower density spirals upward in the center of the cyclone separation cylinder 1, and is discharged into the dust suction bag through the connecting pipe 3 and the extraction component 2. The dust suction component collects the material discharged by the extraction component 2.

[0073] When the first slide plate 4 slides up and down, the moving first slide plate 4 drives the insertion rod 7 to move up and down synchronously. Because the multiple locking slots 8 are arranged vertically in parallel, and because the elastic force of the first elastic member 9 acts on the insertion rod 7, the moving first slide plate 4 causes the outer end of the insertion rod 7 to move up and down within the multiple locking slots 8 until the outer end of the insertion rod 7 is locked within the locking slot 8. At this time, the first slide plate 4 is confined between the two locking slides 6. When the first slide plate 4 moves up and down between the two locking slides 6, the moving first slide plate 4 uses the connecting bar 401 to cause the cross bar 402 to drive the connecting tube 3 up and down. The connecting tube 3 that moves downward squeezes the corrugated portion 5, and the connecting tube 3 that moves upward stretches the corrugated portion 5.

[0074] In addition, during the lifting process of the connecting pipe 3, the top end of the vertical rod 15 is sleeved on the outer side of the annular groove of the second rotating plate 13 by means of the collar 151. The connecting pipe 3 that moves up and down uses the collar 151 to make the vertical rod 15 move up and down inside the through hole of the semicircular ring 14, so that the connecting pipe 3 always extends and contracts in the vertical direction. The collar 151 uses the second rotating plate 13 to limit the connecting pipe 3, preventing the connecting pipe 3 from moving horizontally at the top end of the connecting bar 401 by means of the cross bar 402, so that the corrugated portion 5 is always in a vertical state.

[0075] The air volume baffle 10 rotates within the connecting pipe 3 via the adjusting shaft 11. The rotating air volume baffle 10 tilts within the connecting pipe 3, and the rotation of the air volume baffle 10 adjusts the air volume within the connecting pipe 3. By rotating the adjusting shaft 11, the rotational state of the air volume baffle 10 within the connecting pipe 3 is changed, facilitating real-time changes in the air volume flowing within the connecting pipe 3, thereby determining the effect of the rotating air flow velocity within the cyclone separation drum 1 on the material separation experiment.

[0076] Under the action of centrifugal force, the seeds with higher density spirally move downward along the wall of the cyclone separation cylinder 1 to the second outlet 102 of the cyclone separation cylinder 1, and are discharged into the collection bin 20 through the second outlet 102 and the connecting port. The collection bin 20 is used to collect the seeds with higher density.

[0077] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
