Description

Technical Field

[0001] This invention relates to the field of centrifugal extractor technology, and more particularly to a tank centrifugal extractor. Background Technology

[0002] A tank centrifugal extractor is a device that uses centrifugal force to separate components of different densities in a liquid mixture. It generates a strong centrifugal force through high-speed rotation, causing the heavy phase and light phase in the mixture to move toward the outer wall of the drum and the central axis, respectively, thereby achieving stratification and separation. This device has a compact structure, small footprint, large processing capacity, low power consumption, high degree of automation, simple operation, and can achieve closed operation of the extraction system, providing a good operating environment.

[0003] Although existing tank centrifugal extractors have shown good performance in many applications, they still have some defects and limitations. First, existing multistage centrifugal extractors usually need to be connected by multiple piping systems, and the connection of the piping requires multiple bolts to ensure a sealed connection between the multistage centrifugal extractors.

[0004] However, in practical applications, users may need to flexibly choose to use a single extraction tank or a multi-stage series extraction system according to specific extraction needs. However, existing tank centrifugal extractors often lack this flexibility and are difficult to adapt to changing process requirements. When changing processing needs, workers need to disassemble and reassemble pipelines to complete the conversion of the tank centrifugal extractor, which is not only time-consuming and labor-intensive, but also greatly reduces the production efficiency of the equipment.

[0005] Therefore, a tank centrifugal extractor was proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a tank centrifugal extractor.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a tank centrifugal extractor, comprising an extraction tank, and an inlet pipe and an outlet pipe disposed on the extraction tank, wherein both the inlet pipe and the outlet pipe are equipped with valves. Three extraction tanks are provided, and a conversion block is provided between each extraction tank. The conversion block is provided with an installation mechanism for mounting on two adjacent extraction tanks. An L-shaped cavity is formed inside the conversion block, and a discharge hopper is fixedly connected to the bottom end of the L-shaped cavity. A feed hopper is fixedly connected to the top end of the other end of the L-shaped cavity. An L-shaped lower cavity is formed at the bottom end of the L-shaped cavity. An L-shaped tube is fixedly connected through the side wall of the conversion block relative to the position next to the lower cavity. A corrugated pipe is fixedly connected through the side wall of the conversion block relative to the bottom end of the side wall of the L-shaped cavity. A connecting pipe is fixedly connected to the side wall of the corrugated pipe relative to the position next to the outlet pipe. A conversion mechanism for adjusting single-stage or multi-stage extraction modes is provided inside the L-shaped cavity.

[0008] In the above technical solution, the conversion mechanism further includes an electric telescopic cylinder, which is fixedly connected to the top of the conversion block above the L-shaped cavity. The output end of the electric telescopic cylinder is sealed and fixedly connected to a straight rod through the top of the L-shaped cavity. Lower circular perforated plates are fixedly connected to the inner side of the L-shaped cavity relative to the upper and lower sides of the corrugated pipe. Upper circular perforated plates are fixedly connected to the inner side of the L-shaped cavity relative to the lower sides of the L-shaped cavity. A lower sealing gasket is provided between the lower circular perforated plates, and an upper sealing gasket is provided between the upper circular perforated plates. The lower sealing gasket is fixedly connected to the bottom end of the straight rod. An upper rod is fixedly connected to the side wall of the upper sealing gasket. An extrusion frame is fixedly connected to the side wall of the upper rod. An extrusion plate is fixedly connected to the outer wall of the straight rod relative to the side of the extrusion frame. An inclined groove is opened through the side wall of the extrusion plate. A round rod is fixedly connected to the side wall of the extrusion frame relative to the bottom end of the inclined groove.

[0009] In the above technical solution, both sides of the outer wall of the upper sealing gasket and the lower sealing gasket are set in a conical shape, and both the upper sealing gasket and the lower sealing gasket are made of high temperature resistant rubber material.

[0010] In the above technical solution, the round rod is inserted into the inner side of the inclined groove, and a circular ring frame is fixedly connected to the inner side of the upper circular hole plate near the extrusion plate, and the upper rod is slidably connected to the inner side of the circular ring frame.

[0011] In the above technical solution, the installation mechanism further includes bolts, a pair of bolts, grooves on both the front and rear sides of the conversion block, a maintenance plate fixedly connected to the inner side of the groove, the bolts threadedly connected to the maintenance plate, a push plate slidably connected to the inner side of the groove, and the push plate is inclined on both sides, T-shaped blocks fixedly connected to both sides of the outer wall of the conversion block, a pair of T-shaped frames fixedly connected to both sides of the outer wall of the extraction tank, an installation rod slidably connected to both sides of the groove, the installation rod penetrating the side wall of the T-shaped block, an installation groove on the inner side of the T-shaped frame relative to the position next to the installation rod, a sliding plate fixedly connected to the outer wall of the connecting pipe, and a pair of sliding rods fixedly connected to the side wall of the sliding plate.

[0012] In the above technical solution, the mounting rods are all inclined on the side closest to each other, and the inclined surface of the push plate is in contact with the inclined surface of the mounting rod. The side walls of the mounting rods are all fixedly connected with side plates, and the side plates are all fixedly connected with the inner side of the groove. The mounting rods are all inclined on the side furthest from each other, and the inner side of the mounting grooves is all inclined.

[0013] In the above technical solution, further, each of the connecting pipe side walls is fixedly connected with a lower conical sealing ring, and the side end of the slide rod is provided through the inner side of the groove. The side end of the slide rod is inclined, and the inclined surface of the slide rod is in contact with the inclined surface of the push plate. A lower plate is fixedly connected to the side wall of the slide rod, and a return spring is fixedly connected between the side wall of the lower plate and the inner side of the groove.

[0014] In the above technical solution, the bottom end of each L-shaped tube is fixedly connected with an upper conical sealing ring, and the L-shaped tube is positioned above the feed tube.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention, through the setting of the conversion block and conversion mechanism, can flexibly convert the extraction system according to the actual extraction needs, so that multiple extraction tanks can not only operate independently, but also be directly converted when multi-stage extraction is required to perform multi-stage extraction processing, which greatly improves the convenience of the device and increases the flexibility of the device.

[0017] 2. Through the installation mechanism and other structural design, the present invention allows for quick and easy locking of the conversion block between the extraction tanks by simply inserting the conversion block into the T-frame on the extraction tank and then simultaneously rotating the bolts on both sides. At the same time, the sealing connection of the conversion pipeline is completed, greatly improving installation efficiency. Furthermore, if more extraction stages are needed in the future, this design can be easily expanded without requiring large-scale modifications to the existing system, further enhancing the flexibility of the device.

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0030] In practical use, it has been found that users may need to flexibly choose to use a single extraction tank or a multi-stage series extraction system according to specific extraction needs. However, existing tank centrifugal extractors often lack this flexibility and are difficult to adapt to changing process requirements. When changing processing needs, workers need to disassemble and reassemble the pipeline to complete the conversion of the tank centrifugal extractor, which is not only time-consuming and labor-intensive, but also greatly reduces the production efficiency of the equipment. To solve the above problems, the following structure was invented.

[0031] like Figures 1-9 The illustrated tank centrifugal extractor includes an extraction tank 1, and an inlet pipe 2 and an outlet pipe 3 installed on the extraction tank 1 (it should be noted that each extraction tank 1 is equipped with a pump at the outlet end to ensure that the extraction raw material can be quickly discharged into the subsequent extraction tank 1). Both the inlet pipe 2 and the outlet pipe 3 are equipped with valves. Three extraction tanks 1 are provided, and a conversion block 4 is provided between each extraction tank 1. The conversion block 4 is equipped with a mounting mechanism for mounting on adjacent extraction tanks 1, and an L-shaped cavity 5 is formed inside the conversion block 4. The L-shaped cavity 5 is fixedly connected to the bottom end of the discharge hopper 6, and the top end of the other end of the L-shaped cavity 5 is fixedly connected to the feed hopper 7. The bottom end of the L-shaped cavity 5 is provided with an L-shaped lower cavity 8. The side wall of the conversion block 4 is fixedly connected to the L-shaped tube 9 at the position next to the L-shaped lower cavity 8. The side wall of the conversion block 4 is fixedly connected to the bottom end of the side wall of the L-shaped cavity 5. The side wall of the bellows 10 is fixedly connected to the connecting pipe 11 at the position next to the discharge pipe 3. The L-shaped cavity 5 is provided with a conversion mechanism for adjusting the single-stage or multi-stage extraction mode.

[0032] The conversion mechanism includes an electric telescopic cylinder 12, which is fixedly connected to the top of the conversion block 4 above the L-shaped cavity 5. The output end of the electric telescopic cylinder 12 is sealed and connected to a straight rod 13 at the top of the L-shaped cavity 5. Lower circular hole plates 14 are fixedly connected to the inner side of the L-shaped cavity 5 at both the upper and lower sides of the bellows 10. Upper circular hole plates 15 are fixedly connected to the inner side of the L-shaped cavity 5 at both sides of the lower L-shaped cavity 8. A lower sealing gasket 16 is provided between the lower circular hole plates 14, and an upper sealing gasket 17 is provided between the upper circular hole plates 15. The lower sealing gasket 16 is fixedly connected to the bottom of the straight rod 13. An upper rod 18 is fixedly connected to the side wall of the upper sealing gasket 17. An extrusion frame 19 is fixedly connected to the side wall of the upper rod 18. An extrusion plate 20 is fixedly connected to the outer wall of the straight rod 13 next to the extrusion frame 19. An inclined groove 21 is opened through the side wall of the extrusion plate 20. A round rod 22 is fixedly connected to the side wall of the extrusion frame 19 at the bottom of the inclined groove 21.

[0033] Both sides of the outer walls of the upper sealing gasket 17 and the lower sealing gasket 16 are conical, and both the upper sealing gasket 17 and the lower sealing gasket 16 are made of high-temperature resistant rubber.

[0034] Furthermore, the round rod 22 is inserted into the inner side of the inclined groove 21, and the inner side of the upper round hole plate 15 near the extrusion plate 20 is fixedly connected to the ring frame 23, and the upper rod 18 is slidably connected to the inner side of the ring frame 23.

[0035] During stand-alone operation of the tank centrifugal extractor, the extraction material in the first extraction tank 1 can be poured in through the feed pipe 2, while the extraction material in the remaining extraction tanks 1 can be poured in through the feed hopper 7 (at this time, because the upper sealing gasket 17 is sealed on the upper circular perforated plate 15 on the side away from the feed hopper 7, the poured material will flow into the L-shaped lower cavity 8 through another upper circular perforated plate 15, and then be discharged from the L-shaped pipe 9 into the feed pipe 2, and then enter the interior of the extraction tank 1). After the feeding is completed, the valve on the feed pipe 2 is closed to ensure that the material in the extraction tank 1 is within the range of 1. Under normal air pressure, centrifugal extraction can then be performed. After extraction, the valve on the discharge pipe 3 can be opened, and the extractant in the extraction tank 1 can be drawn out by the pump at the discharge end. At this time, the extractant will be discharged from the discharge pipe 3 into the connecting pipe 11 and the bellows 10, and then flow into the L-shaped cavity 5 (at this time, since the lower circular perforated plate 14 above is blocked by the lower sealing gasket 16, the extractant flowing into the L-shaped cavity 5 will pass through another lower circular perforated plate 14 and be discharged from the discharge hopper 6), thus realizing the independent operation of each extraction tank 1;

[0036] When a multi-stage extraction process is required based on production needs, the electric telescopic cylinder 12 can be activated to drive the straight rod 13 to move downwards, thereby moving the lower sealing pad 16 downwards. The pad moves from the upper lower circular hole plate 14 to the lower lower circular hole plate 14, thus sealing the lower lower circular hole plate 14. At the same time, the movement of the straight rod 13 will drive the extrusion plate 20 to move. Under the action of the inclined groove 21 on the extrusion plate 20, the circular rod 22 is pushed (since the upper rod 18 can only move laterally on the ring frame 23, the downward movement of the extrusion plate 20 and the action of the inclined groove 21 pressing the circular rod 22 will drive the extrusion frame 19 and the upper rod 18 to move laterally). This also drives the upper sealing pad 17 to move laterally, thereby moving the upper sealing pad 17 from one of the upper circular hole plates 15 to another upper circular hole plate 15, and pressing the upper sealing pad 17 tightly onto the upper circular hole plate 15, thus achieving rapid adjustment of the extraction system.

[0037] At this point, the extraction parameters of the subsequent extraction tank 1 need to be adjusted to ensure the multi-stage extraction effect of the extraction system. Then, the extract that has been extracted from the first extraction tank 1 will flow into the L-shaped cavity 5 under the action of the pump. Since the lower sealing gasket 16 blocks the lower circular plate 14 below, the extract will then be discharged into the L-shaped lower cavity 8 through the L-shaped cavity 5, and then discharged into the second extraction tank 1 through the L-shaped pipe 9 and the feed pipe 2 for secondary extraction. This process is repeated to achieve the multi-stage extraction effect.

[0038] When it is necessary to adjust the extraction process separately, the electric telescopic cylinder 12 can be started and reset, and the above operation can be repeated in reverse.

[0039] In summary, the above-described structure allows for flexible conversion of the extraction system according to actual extraction needs. This enables multiple extraction tanks 1 to not only operate independently but also to be directly converted for multi-stage extraction processing when multi-stage extraction is required, greatly improving the convenience and flexibility of the device.

[0040] Based on the above embodiments, it was found during use that although the above structure can quickly switch the extraction system, when installing the conversion block 4, it is not only necessary to fix the conversion block 4 between the extraction tanks 1, but also to connect the corresponding pipes, which is time-consuming and laborious. In order to solve the above problems, the above structure has been further improved.

[0041] The mounting mechanism includes bolts 24, a pair of bolts 24, grooves 25 on both the front and rear sides of the conversion block 4, inspection plates 26 fixedly connected to the inside of the grooves 25, bolts 24 threadedly connected to the inspection plates 26, push plates 27 slidably connected to the inside of the grooves 25, and the push plates 27 are inclined on both sides, T-blocks 28 fixedly connected to both sides of the outer wall of the conversion block 4, a pair of T-frames 29 fixedly connected to both sides of the outer wall of the extraction tank 1, mounting rods 30 slidably connected to both sides of the grooves 25, the mounting rods 30 penetrating the side walls of the T-blocks 28, mounting grooves 31 on the inside of the T-frames 29 relative to the position next to the mounting rods 30, and a sliding plate 36 fixedly connected to the outer wall of the connecting pipe 11, a pair of sliding rods 37 fixedly connected to the side walls of the sliding plate 36;

[0042] The mounting rods 30 are all inclined on the side closest to each other, and the inclined surface of the push plate 27 is in contact with the inclined surface of the mounting rods 30. The side walls of the mounting rods 30 are all fixedly connected with side plates 32. The side plates 32 and the inner side of the groove 25 are all fixedly connected with return springs 33. The mounting rods 30 are all inclined on the side furthest from each other, and the inner side of the mounting groove 31 is all inclined.

[0043] The side walls of the connecting pipe 11 are all fixedly connected with a lower conical sealing ring 35, and the side end of the slide rod 37 is set through the inner side of the groove 25. The side end of the slide rod 37 is inclined, and the inclined surface of the slide rod 37 is in contact with the inclined surface of the push plate 27. The side wall of the slide rod 37 is fixedly connected with a lower plate 38, and a return spring 39 is fixedly connected between the side wall of the lower plate 38 and the inner side of the groove 25.

[0044] The bottom end of the L-shaped tube 9 is fixedly connected with an upper conical sealing ring 34, and the L-shaped tube 9 is positioned above the feed tube 2.

[0045] During the installation of extraction tank 1, multiple extraction tanks 1 are first fixed to the ground at their bottom ends in sequence (it should be noted that the gap size between each extraction tank 1 is fixed, and the gap between the T-shaped frames 29 on two extraction tanks 1 is the same as the width of the conversion block 4). Then, the T-shaped blocks 28 on the conversion block 4 are inserted into the corresponding T-shaped frames 29 (at this time, the L-shaped tube 9 will be inserted above the feed pipe 2, and the upper conical sealing ring 34 will be inserted into the feed pipe 2 partly, while the lower conical sealing ring 35 will be moved to the side of the discharge pipe 3, but the two are not aligned). Then, the bolts 24 on both sides are rotated and moved inward. At this time, the push plate 27 will be pushed to slide inside the groove 25, and the inclined surface of the push plate 27 will press the inclined surface of the mounting rod 30 (since the mounting rod 30 can only slide laterally on the T-shaped block 28, it will be pushed to slide to both sides under the pressure of the inclined surface of the push plate 27).

[0046] This causes the installation rod 30 to be inserted into the corresponding installation groove 31 at the opposite end. At this time, the inclined surface of the installation rod 30 on the opposite side will press against the inclined surface inside the installation groove 31. Since the position of the extraction tank 1 is fixed and the conversion block 4 can move up and down, the inclined surface of the installation rod 30 will press against the inclined surface of the installation groove 31, gradually pressing the conversion block 4 and the T-block 28 downward. At the same time, it will drive the upper conical sealing ring 34 downward, so that the upper conical sealing ring 34 is tightly pressed against the feed pipe 2. At the same time, it will drive the lower conical sealing ring 35 downward, so that the lower conical sealing ring 35 moves to the position aligned with the discharge pipe 3. At the same time, it will drive the side plate 32 to move and compress the reset spring 33. (During this process, the inclined surface of the push plate 27 will press against the inclined surface of the slide rod 37, thereby pushing the slide rod 37 to drive the slide plate 36 and the lower conical sealing ring 35 to move towards the discharge pipe 3. However, at this time, the lower conical sealing ring 35 will not be inserted into the discharge pipe 3, affecting the normal downward movement of the conversion block 4.)

[0047] Subsequently, the inclined surface of the mounting rod 30 moves out from the inclined surface of the mounting groove 31, and the mounting rod 30 moves to the plane of the mounting groove 31. At this time, the upper conical sealing ring 34 is already tightly inserted into the feed pipe 2. However, as the push plate 27 continues to move, the inclined surface of the push plate 27 will squeeze the inclined surface of the slide rod 37 (at the same time, it will drive the lower plate 38 to move and compress the return spring 39), causing the slide plate 36 to drive the docking pipe 11 to move, inserting the lower conical sealing ring 35 into the corresponding discharge pipe 3. At this time, the mounting rod 30 will slide in the mounting groove 31, thereby tightly squeezing the lower conical sealing ring 35 into the discharge pipe 3, completing the rapid docking between the feed pipe 2 and discharge pipe 3 of the two extraction tanks 1 and the conversion block 4.

[0048] In summary, with the above structural design, simply inserting the conversion block 4 into the T-shaped frame 29 on the extraction tank 1 and then simultaneously rotating the bolts 24 on both sides will quickly lock and fix the conversion block 4 between the extraction tanks 1. At the same time, the sealing connection of the conversion pipeline will be completed, which greatly improves the installation efficiency. Furthermore, if more extraction stages are needed in the future, this design can be more easily expanded without large-scale modifications to the existing system, further improving the flexibility of the device.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0050] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
