Description

Technical Field

[0001] This invention relates to the field of Fischer-Tropsch wax production technology, specifically to a continuous drying apparatus for Fischer-Tropsch wax production. Background Technology

[0002] Fischer-Tropsch wax is an alkane polymer synthesized from hydrocarbon-based syngas or natural gas. It mainly relies on high-quality and inexpensive raw materials from coal chemical industry for iron-based or cobalt-based synthesis, and has a significant price advantage over crude oil wax. In the production of Fischer-Tropsch wax, it is necessary to remove free water, bound water or trace solvents from the wax through a drying process to avoid clumping, mold growth or affecting subsequent modification during storage or use.

[0003] The following problems were found in the existing technology: In the drying process, the disc dryer has the best drying effect for drying powder. However, the blades of the existing disc dryer only sweep the powder and spread it out repeatedly for drying. However, due to the characteristics of the powder, the powder will inevitably accumulate and clump during the initial drying process due to the presence of free water inside the powder. This makes it difficult to dry the clumped powder thoroughly, which affects the production quality of Fischer-Tropsch wax.

[0004] To address the aforementioned issues, there is an urgent need for innovative design of the existing continuous drying unit for Fischer-Tropsch wax production. Summary of the Invention

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-13 The present invention provides a technical solution: a continuous drying device for Fischer-Tropsch wax production, comprising an outer shell 1, a geared motor assembly fixedly connected to the bottom wall of the outer shell 1, a shaft 2 fixedly connected to the main shaft end of the geared motor assembly, and a bearing 3 provided on the outer wall of the shaft 2, and an accommodating cavity 4 opened on the inner wall of the outer shell 1.

[0041] The inner wall of the cavity 4 is provided with a number of support rods 5 arranged in a ring on the outer wall of the shaft 2, and the support rods 5 are equipped with an extrusion mechanism 6 for extruding powder.

[0042] Several support rods 5 are arranged vertically at equal intervals on the shaft 2 in several groups.

[0043] In this embodiment, as Figure 1 and Figure 2 As shown, the support member 3 includes a support frame 31 fixed in the inner wall of the housing. Several outer support plates 32 and several inner support plates 33 are fixedly connected inside the support frame 31. The several outer support plates 32 and several inner support plates 33 are placed alternately, and the several outer support plates 32 and several inner support plates 33 are all arranged in a one-to-one correspondence with several sets of support rods 5.

[0044] The outer diameter of the outer support plate 32 is smaller than that of the inner support plate 33, and several discharge ports are opened at the center of the inner support plate 33. Through the arrangement of the inner support plate 33, the outer support plate 32, and several cutter heads 64, the operator can adjust the position of the cutter heads 64 by adjusting the angle of the mounting box 63. The cutter heads 64 of the outer support plate 32 are set outward, and the cutter heads 64 of the inner support plate 33 are set inward. This allows the material on the outer support plate 32 to be continuously pushed outward by the cutter heads 64, so that the material can be swept out of the outer support plate 32 and fall into the inner support plate 33. The material in the inner support plate 33 is pushed in the opposite direction, so that the material in the inner support plate 33 is continuously pushed inward until it is discharged from the discharge port of the inner support plate 33 and falls into the outer support plate 32 below. By continuously pushing the material back and forth, the drying effect of the material is increased.

[0045] In this embodiment, as Figure 3 , Figure 4 , Figure 6 , Figure 9 , Figure 10 , Figure 13 As shown, the extrusion mechanism 6 includes a bearing chamber 61 fixed to the outer wall of the support rod 5. A damping bearing 62 is fixedly connected to the bottom end of the bearing chamber 61, and a mounting box 63 is rotatably connected to the bottom end of the damping bearing 62. A cutter head 64 is fixedly connected to the bottom end of the mounting box 63. An extrusion plate 65 is attached to the top wall of the mounting box 63, and slide rods 66 are provided through both ends of the extrusion plate 65. The ends of the slide rods 66 are fixedly connected to the inner wall of the mounting box 63. A slidable wedge is horizontally provided at the bottom end of the extrusion plate 65. The wedge-shaped block 67 has a transmission rod 68 inserted at its center, and both ends of the transmission rod 68 are fixedly connected to a slow return assembly 69. A toothed plate 610 is fixedly connected to one side of the wedge-shaped block 67, and an L-shaped vibration rod 611 is horizontally arranged at the top of the toothed plate 610. A plug-in block 612 is rotatably connected to the inner wall of the vibration rod 611 through a half-circle limiting shaft. The vibration rod 611 is a spring telescopic rod structure. The outer wall of the wedge-shaped block 67 is connected to the inner wall of the mounting box 63 through a return spring.

[0046] A baffle 613 is rotatably connected to the inner wall of the mounting box 63, and connecting plates 614 are slidably inserted into both ends of the baffle 613. The top ends of the two connecting plates 614 are fixedly connected to the same push rod 615. A slot for installing a vibrating rod 611 is opened at the center of the push rod 615, and the bottom end of the vibrating rod 611 is rotatably connected to the top end of the baffle 613. The toothed plate 610 on the side wall of the wedge block 67 moves synchronously, and the vibrating rod 611 is reset to its original position by the insertion block 612 hinged to the half-circle limiting shaft. During contact, the plug-in block 612 is rotatable at half a circle, allowing it to move up and down intermittently as it passes through the toothed groove on the toothed plate 610. The vibrating rod 611 is a spring telescopic rod structure, causing it to intermittently change from a contracted state to an extended state. During this process, the fixed and movable ends of the vibrating rod 611 continuously impact each other, generating a vibration effect. This vibration acts on the baffle 613, causing the baffle 613 to vibrate down the attached powder during its reset process, preventing adhesion.

[0047] In this embodiment, as Figure 5 , Figure 9 , Figure 10 and Figure 11As shown, a first spiral groove 616 is formed on the outer wall of the transmission rod 68, and the other end of the first spiral groove 616 is connected to a second spiral groove 617. The first spiral groove 616 and the second spiral groove 617 are connected end to end, and a limit block is slidably connected in the first spiral groove 616. The groove depths of the first spiral groove 616 and the second spiral groove 617 gradually decrease from left to right. The top of the limit block is fixedly connected to the inner wall of the wedge block 67. When the limit block fixedly set in the inner wall of the wedge block 67 slides in the first spiral groove 616, the first spiral groove 616... The depth of the first spiral groove 616 and the second spiral groove 617 gradually decreases from left to right. Moreover, the first spiral groove 616 and the second spiral groove 617 are connected end to end. As the wedge block 67 moves initially, the limiting block moves to the shallowest position of the first spiral groove 616 and falls into the deepest part of the second spiral groove 617. This allows the limiting block to pass stably and continuously through the first spiral groove 616 and the second spiral groove 617. Furthermore, the lengths of the first spiral groove 616 and the second spiral groove 617 are different, which causes the rotation amplitude of the transmission rod 68 to be different when the limiting block passes through them.

[0048] In this embodiment, as Figure 9 , Figure 10 and Figure 12 As shown, the rotation direction of the plug block 612 is the same as the movement direction of the wedge block 67. The outer diameter of the plug block 612 matches the inner diameter of the tooth groove on the toothed plate 610, so that the unidirectional rotatable setting of the plug block 612 can shake off the sticky material by vibration when the baffle 613 is reset.

[0049] In this embodiment, as Figure 9 , Figure 10 and Figure 13 As shown, the slow return assembly 69 includes a positioning frame 691 slidably disposed in the inner wall of the mounting cavity, and a first actuating rod 692 is rotatably connected to the bottom end of the positioning frame 691. A cavity 693 is provided on the outer wall of the first actuating rod 692. A first slider 694 is slidably connected in the inner wall of the first actuating rod 692. A transmission disk 695 is rotatably connected to the rear end of the first slider 694. The transmission disk 695 and the transmission rod 68 are fixedly connected. The transmission disk 695 is fixedly connected to the inner wall of the mounting cavity through a bushing.

[0050] The top of the first actuating rod 692 is rotatably connected to the second slider 696, and the second slider 697 is slidably sleeved on the second slider 696. The top of the second actuating rod 697 is fixedly connected to the sliding seat 698, and the bottom of the sliding seat 698 is fixedly connected to the support plate 699. The bottom of the support plate 699 is rotatably connected to the push rod 615. When the transmission rod 68 rotates in the opposite direction, the first slider 694 gradually moves to the upper end of the first actuating rod 692 and pushes the first actuating rod 692 to move to the right. Since the first actuating rod 692 is pushed to deflect to the right by the upper part of the first actuating rod 692, the deflection radius of the first actuating rod 692 becomes larger, and the offset time and speed of the first actuating rod 692 are slower, so that the upper sliding seat 698 slowly resets, and the baffle 613 can slowly return to its original position when resetting, avoiding the powder flying due to rapid reset, and providing time for subsequent vibration.

[0051] In this embodiment, as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the extrusion mechanism 6 also includes an extrusion rod 618 that is vertically slidably disposed with the bearing chamber 61. The bottom end of the extrusion rod 618 passes through the damping bearing 62 and is fixedly connected to the top end of the extrusion plate 65. An inclined groove 619 is provided on the side wall of the extrusion rod 618, and a sliding block 620 is slidably connected in the inner wall of the inclined groove 619. A trigger rod 621 that is slidably disposed inside the support rod 5 is fixedly connected to the end of the sliding block 620. A push plate 622 is fixedly connected to the outer wall of the end of the trigger rod 621.

[0052] A push post 623 is attached to the outer wall of the push plate 622, and a toggle gear 624 is fixedly connected to the top of the push post 623. An external toothed ring 625 is meshed on the right side wall of the toggle gear 624, and the external toothed ring 625 is fixed inside the receiving cavity 4. An internal toothed post 626 sleeved on the shaft 2 is meshed on the left side of the toggle gear 624.

[0053] A return spring is fixedly connected to the end of the trigger rod 621, and the end of the return spring is fixedly connected to the inner wall of the support rod 5. The shaft 2 drives the internal gear column 626 to rotate. At this time, since a toggle gear 624 is provided between the internal gear column 626 and the external gear ring 625, when the internal gear column 626 rotates, it drives the toggle gear 624 to rotate in the opposite direction to the shaft 2 inside the external gear ring 625. At the same time, the shaft 2 drives several sets of support rods 5 to rotate synchronously. Since the toggle gear 624 and the support rod 5 move in opposite directions, the push column 623 at the bottom of the toggle gear 624 will contact the push plate 622, which pushes the push plate 622 and the trigger rod 621 to move together, and the trigger rod 621 compresses the spring.

[0054] The sliding block 620 on the trigger rod 621 will press against the inclined groove 619, causing the inclined groove 619 to be pressed and push the extrusion rod 618 downward. The extrusion rod 618 simultaneously drives the extrusion plate 65 to move downward. Since the extrusion plate 65 is connected to the sliding rod 66, the extrusion plate 65 can move downward stably, thereby triggering the operation of the extrusion mechanism 6.

[0055] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, a ventilation pipe 627 for circulating heat is fixedly connected to the inner wall of the mounting box 63, and one end of the ventilation pipe 627 is connected to a pump. The pump is fixed to the outer wall of the support rod 5. The spray direction of the ventilation pipe 627 is the same as the inner side of the baffle 613. With the pump, the high-temperature airflow inside the outer shell 1 can be drawn in and sprayed out through the ventilation pipe 627 to heat and dry the powder squeezed on the baffle 613, thus avoiding affecting the drying effect.

[0056] The method of use and advantages of this invention: The continuous drying device for Fischer-Tropsch wax production operates as follows:

[0057] like Figures 1 to 13 As shown, the worker manually pours Fischer-Tropsch wax powder into the top of the outer shell 1. The geared motor drives the shaft 2 to rotate, and the shaft 2 drives the internal gear column 626 to rotate. At this time, since there is a turning gear 624 between the internal gear column 626 and the external gear ring 625, when the internal gear column 626 rotates, it drives the turning gear 624 to rotate in the opposite direction to the shaft 2 inside the external gear ring 625. At the same time, the shaft 2 drives several sets of support rods 5 to rotate synchronously. Since the turning gear 624 and the support rods 5 move in opposite directions, the push column 623 at the bottom of the turning gear 624 will contact the push plate 622, which pushes the push plate 622 and the trigger rod 621 to move together. The trigger rod 621 compresses the spring.

[0058] The sliding block 620 on the trigger rod 621 will press against the inclined groove 619, causing the inclined groove 619 to be pressed and push the pressing rod 618 downward. The pressing rod 618 simultaneously drives the pressing plate 65 to move downward. Because the pressing plate 65 is connected to the sliding rod 66, the pressing plate 65 can move downward stably. At this time, the pressing plate 65 contacts the wedge block 67, and the wedge block 67 moves under pressure. At this time, the limiting block fixed in the inner wall of the wedge block 67 slides in the first spiral groove 616. The groove depth of the first spiral groove 616 and the second spiral groove 617 gradually becomes shallower from left to right. The first spiral groove 616 and the second spiral groove 617 are connected end to end. As the wedge block 67 moves initially, the limiting block moves to the shallowest position of the first spiral groove 616 and falls into the deepest part of the second spiral groove 617. During the movement of the limiting block, it will also press the groove wall of the first spiral groove 616. Moreover, the groove length of the first spiral groove 616 is relatively short, causing the transmission rod 68 to rotate quickly by a small angle.

[0059] At this time, due to the rotation of the transmission rod 68, the transmission rod 68 synchronously drives the transmission disk 695 to rotate. At this time, the first slider 694 rotating on the transmission disk 695 changes position along with the rotation of the transmission disk 695. At the same time, the cavity 693 provided on the first actuating rod 692 and the first slider 694 are slidably connected, so that when the first slider 694 performs a circular motion in the vertical direction, the first slider 694 moves downward on the first actuating rod 692 and pushes the first actuating rod 692 to the left. Since it pushes the first actuating rod 692 to rotate at the lower end of the first actuating rod 692, its radius of motion is small, which allows the first actuating rod 692 to swing to the left quickly.

[0060] Next, a second sliding block 696 is mounted on the first actuating rod 692 and fitted with a second actuating rod 697. As the first actuating rod 692 moves to the left, the second actuating rod 697 moves to the left in sync, thus pushing the sliding block 698 to the left. At the same time, the support plate 699 at its bottom pushes the push rod 615. Since the push rod 615 and the baffle 613 are slidably connected, the push rod 615, under the force from the left side of the support plate 699, can push the baffle 613 to rotate to the right. As the baffle 613 moves closer to the cutter head 64, a large amount of powder is located between the baffle 613 and the cutter head 64. Thus, this powder can be squeezed by the baffle 613. If there are lumpy powders inside, they will break due to the squeezing force.

[0061] Then, when the baffle 613 rotates to its maximum distance, the push post 623 on the actuating gear 624 also pushes the push plate 622 to its maximum position. Since the actuating gear 624 is always in motion, as the actuating gear 624 moves past the push plate 622 at its current position, the trigger rod 621 will begin to reset via the spring. The reset of the trigger rod 621 will reset the pressing plate 65 of the pressing wedge block 67 via the inclined groove 619. During the reset process of the wedge block 67 by the reset spring, the limiting block in the wedge block 67 is located in the second spiral groove 617, and the length of the second spiral groove 617 is greater than that of the first spiral groove 616, so that the wedge block 67... The longer distance and time it moves result in a longer reset time for the transmission rod 68. When the transmission rod 68 rotates in the opposite direction, the first slider 694 gradually moves to the upper end of the first actuating rod 692 and pushes the first actuating rod 692 to the right. Since the first actuating rod 692 is pushed to the right by the upper part of the first actuating rod 692, the deflection radius of the first actuating rod 692 becomes larger, and thus the offset time and speed of the first actuating rod 692 are slower, so that the upper sliding seat 698 slowly resets. This allows the baffle 613 to slowly return to its original position during reset, avoiding the flying of powder caused by rapid reset and providing time for subsequent vibration.

[0062] Simultaneously, during the resetting process of the wedge block 67, the toothed plate 610 on the side wall of the wedge block 67 moves synchronously. When the vibrating rod 611 contacts the toothed plate 610 through the insertion block 612 hinged by the half-circle limiting shaft, the insertion block 612 can be rotated in half-circle, allowing it to move up and down intermittently as it passes through the toothed groove on the toothed plate 610. Furthermore, the vibrating rod 611 is designed as a spring telescopic rod, causing it to intermittently change from a contracted state to an extended state. During this process, the fixed end and the movable end of the vibrating rod 611 continuously impact each other, generating a vibration effect. This vibration acts on the baffle 613, allowing the baffle 613 to vibrate down the attached powder during the resetting process, preventing adhesion.
