Description

Technical Field

[0001] This invention relates to the field of isostatic graphite calcination technology, and more specifically, to an ultrasonically etched isostatic graphite strength-enhancing calcination furnace. Background Technology

[0002] A calcining furnace is a high-temperature heat treatment device used to heat-treat raw materials at high temperatures to achieve certain physical and chemical properties. In the production process of isostatic graphite by ultrasonic etching, the calcining furnace plays a crucial role. Calcination at high temperatures can promote the rearrangement and densification of the graphite crystal structure, further improving the strength and high-temperature resistance of the material.

[0003] A search of existing literature revealed that Chinese Patent Publication No. CN115854713B discloses a pressure calcining furnace for isostatic graphite preparation. This furnace utilizes a venting assembly located at the upper end of a positioning sleeve. The venting assembly includes a movable top cover, a rubber sealing cover, and several second venting mechanisms. The movable top cover is positioned above a supporting baffle, and the rubber sealing cover is fixedly located inside the movable top cover. Several second venting mechanisms are evenly arrayed at the upper end of the supporting baffle, and each second venting mechanism includes a vent pipe. These vent pipes release the gas inside the reaction chamber to the outside of the device. However, this calcining furnace has the following drawbacks.

[0004] When calcining ultrasonically etched isostatic graphite, the aforementioned calcination furnace requires placing various raw materials of ultrasonically etched isostatic graphite into the furnace for calcination. During the calcination process, the entire ultrasonically etched isostatic graphite mixture is difficult to fully compress and mix within the furnace, resulting in poor contact uniformity and poor heat conduction uniformity among the raw materials, longer calcination time, and significantly reduced calcination efficiency. Therefore, a calcination furnace for improving the strength of ultrasonically etched isostatic graphite is provided. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ultrasonic etching isostatic pressing graphite strength enhancement calcination furnace.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic etching isostatic pressing graphite strength-enhancing calcining furnace, comprising a calcining furnace insulation shell, wherein a calcining furnace is fixedly connected inside the calcining furnace insulation shell, and a multi-directional movable mechanism is installed inside the calcining furnace.

[0007] The multi-directional movable mechanism includes a fusion gravity ball installed inside the calcining furnace, and a support shaft is rotatably connected inside the fusion gravity ball. One end of the support shaft is equipped with a concave sleeve with a concave vertical cross-section. A support linkage shaft is connected to the top of the concave sleeve near its center. A linkage sleeve ring is vertically slidably connected to the outer wall of the support linkage shaft. Linkage ring groove shafts are fixedly connected to both sides of the linkage sleeve ring. A limit rotation mechanism is provided on the outer wall of the linkage ring groove shaft. An auxiliary linkage component is provided on one side of the outer wall of the calcining furnace insulation shell.

[0008] Preferably, the concave sleeve is fixedly connected to the support shaft and the support linkage shaft respectively, and the center point of the support shaft and the center point of the vertical section of the fused gravity rolling ball are on the same horizontal line. The diameter of the top inner wall of the roasting furnace is larger than the diameter of its bottom inner wall, and the bottom inner wall of the roasting furnace is rounded.

[0009] Preferably, a slidably connected limiting ring is installed on the outer wall of the supporting linkage shaft above the linkage sleeve ring, and the limiting ring and the linkage sleeve ring are integrally formed. A heater is installed at the bottom of the inner wall of the calcining furnace insulation shell below the calcining furnace, and the heater is fixedly connected to the calcining furnace insulation shell. Limiting support rings are provided on both sides of the outer side of the fusion gravity rolling ball and fixedly connected to the supporting shaft. Both limiting support rings are rotatably connected to the fusion gravity rolling ball, and the two limiting support rings are symmetrically arranged about the fusion gravity rolling ball. A discharge hopper is fixedly connected to one side of the outer wall of the calcining furnace near its top.

[0010] By adopting the above technical solution, the ultrasonically etched isostatic graphite calcining raw material is transported into the calcination furnace through the hopper. Under the action of gravity, the fusion gravity ball rolls on the outer wall of the support shaft. Two limiting rings limit the fusion gravity ball to the left and right. The support shaft drives the concave sleeve frame to move the support linkage shaft left and right. At the same time, the support linkage shaft moves up and down along the inner wall of the linkage sleeve ring and the limiting ring. The support shaft drives the linkage ring groove shaft to rotate inside the support ring, and the connecting support block supports the support ring. The entire fusion gravity ball can fully compress and contact the ultrasonically etched isostatic graphite calcining raw material inside the calcination furnace.

[0011] Preferably, the limiting rotation mechanism includes a support ring rotatably disposed on the outer wall of the linkage ring groove shaft, and a connecting block is fixedly connected to the upper part of the outer wall of the support ring. A linkage rotating ring with a cross-sectional shape of annular is fixedly installed on one side of the connecting block. Multiple linkage blocks are fixedly connected in an annular pattern at equal intervals on the outer wall of the linkage rotating ring, and a concave groove ring is provided at the bottom end of the linkage block. Multiple limiting shaft rings are distributed in an annular pattern at equal intervals on the inner wall of the concave groove ring. Each limiting shaft ring has rolling balls connected inside. An annular groove is opened below the concave groove ring, and an annular groove cover plate that is vertically slidably inserted into the roasting furnace is installed below the annular groove. A sleeve through hole is rotatably connected to the top end of the concave groove ring. The device comprises a sleeve with a connecting through-hole block inside, a fitting collar fixedly connected to the connecting through-hole block at the bottom end of the sleeve, a limiting ball, a limiting block, and a support block arranged sequentially from bottom to top inside the fitting collar, a sleeve support block fixedly connected to one side of the outer wall of the connecting through-hole block, a fixed support column inserted at the top of the sleeve support block, a fixed connection between the bottom end of the connecting through-hole block and the top end of the annular groove cover plate, a concave grooved ring fixedly connected to the linkage annular groove shaft and the linkage support block respectively, a rolling connection between the ball and the annular groove cover plate to which the annular groove belongs, a fixed connection between the sleeve and the limiting block and the support block respectively, and a rolling connection between the limiting ball and the fitting collar respectively.

[0012] By adopting the above technical solution, the connecting support block drives the linkage rotating ring to rotate, and multiple linkage support blocks drive the concave groove ring to rotate and change direction in the annular groove inside the annular groove cover plate. The concave groove ring drives the limiting shaft ring to make multiple balls roll inside the annular groove. The linkage support block drives the concave groove ring to rotate the connecting support block, and the connecting support block drives the support ring to rotate the linkage ring groove shaft. The linkage ring groove shaft drives the linkage sleeve ring to rotate and change angle. The entire support linkage shaft drives the concave sleeve frame to rotate the support shaft rod, and the support shaft rod drives the fusion gravity rolling balls. The material undergoes multi-directional, irregular extrusion and rolling inside the roasting furnace, achieving full rolling extrusion at multiple angles within the furnace. Fixed pillars support the connecting blocks, which in turn support the connecting through-hole blocks, which in turn support the connecting cylinder. The connecting cylinder provides vertical support to the support blocks, which in turn support the limiting blocks. The limiting blocks then limit the movement of the limiting balls, which roll within the limiting blocks and the fitting collar, ensuring that the concave grooved ring rotates vertically within the annular groove.

[0013] Preferably, the auxiliary linkage component includes a rotating shaft disposed on one side of the outer wall of the calcining furnace insulation shell, with an angle sensor coaxially connected to one end of the rotating shaft. A sleeve bracket is rotatably connected to the outer wall of the rotating shaft via a bearing. A linkage slider is fixedly connected to the bottom end of the calcining furnace insulation shell near its center. An arc-shaped slide plate is slidably connected to the outer wall of the linkage slider. A reinforcing block is fixedly connected to the sleeve bracket below the outer wall of the arc-shaped slide plate. A fixing block is fixedly connected to the other side of the outer wall of the calcining furnace insulation shell via bolts. One side of the device is provided with a driven shaft that is rotatably connected to the sleeve bracket. A driven gear is installed on the outer wall of the driven shaft near its front end. A drive gear is installed below the driven gear. A drive chain for driving the driven gear is meshed and connected to the outer wall of the drive gear. A drive reduction motor is inserted and fixed inside the drive gear. The angle sensor is fixedly installed between the sleeve bracket and the furnace insulation shell. The driven gear and the furnace insulation shell are both fixedly connected to the driven shaft. The center point of the driven shaft is at the same level as the center point of the rotating shaft.

[0014] By adopting the above technical solution, the drive gear motor is started, causing the drive gear to rotate 45 degrees clockwise. The drive gear drives the drive chain, causing the driven gear to rotate. The driven gear drives the driven shaft to rotate 45 degrees clockwise inside the sleeve bracket. The driven shaft drives the fixed block, causing the calcining furnace insulation shell to rotate. The calcining furnace insulation shell drives the rotating shaft to rotate. The rotating shaft drives the angle sensor sensing end to rotate and sense the angle. The sleeve bracket ensures the stable rotation of the rotating shaft. At the same time, the calcining furnace insulation shell drives the linkage slider to rotate. The linkage slider slides inside the arc-shaped slide plate. Then, the drive gear motor is started again, causing the drive gear to rotate 45 degrees counterclockwise. The drive gear drives the drive chain, causing the driven gear to rotate. The driven gear drives the driven shaft, causing the fixed block to rotate. The fixed block drives the calcining furnace insulation shell, causing the rotating shaft to rotate. The rotating shaft senses the angle sensor output end. In this way, the drive gear motor switches between forward and reverse, causing the calcining furnace inside the entire calcining furnace insulation shell to shake back and forth.

[0015] The technical effects and advantages of this invention are as follows:

[0016] This invention employs a multi-directional moving mechanism that integrates gravity-driven rolling balls that roll on the outer wall of a support shaft under the influence of gravity. The support shaft drives a concave sleeve frame to move the support linkage shaft left and right. Simultaneously, the support linkage shaft moves up and down along the inner walls of the linkage sleeve ring and the limiting ring. The connecting block drives the linkage rotating ring to rotate the linkage block. The linkage block drives the concave groove ring to rotate and switch directions in the annular groove inside the annular groove cover plate. The concave groove ring drives the limiting shaft ring to make multiple balls roll inside the annular groove. The linkage ring groove shaft drives the linkage sleeve ring to rotate and switch angles. The support shaft drives the integrated gravity-driven rolling balls to roll irregularly in multiple directions inside the calcining furnace. The ultrasonically etched isostatic graphite calcining raw material undergoes full compression and contact calcination at multiple points, resulting in better contact uniformity, faster heat conduction uniformity, and shorter calcination time, significantly improving calcination efficiency and enhancing the strength of the ultrasonically etched isostatic graphite.

[0017] This invention employs a limiting rotation mechanism to support the sleeve cylinder with the sleeve through hole block, and the lower surface of the limiting ball is pressed against the position above the concave groove ring. The sleeve cylinder provides vertical support to the support block, and the limiting block limits the limiting ball. The limiting ball rolls inside the limiting block and inside the fitting shaft ring, and the concave groove ring rotates vertically within the annular groove. This multi-directional stable switching can improve the contact effect of isostatic graphite calcination raw materials fused with gravity rolling ball extrusion and ultrasonic etching.

[0018] This invention uses an auxiliary linkage component to start a drive reduction motor that drives the drive gear to rotate 45 degrees forward. The drive gear then drives the drive chain to rotate the driven gear. The rotating shaft drives the angle sensor to rotate and sense the angle. The linkage slider slides inside the arc-shaped slide plate. After the drive reduction motor is started again and drives the drive gear to rotate 45 degrees backward, the fixed block drives the heat insulation shell of the roasting furnace to rotate the rotating shaft. The multi-angle stable shaking allows the ultrasonically etched isostatic graphite roasting raw material inside the roasting furnace to shake and roast fully, resulting in more uniform contact between the raw materials.

[0019] Through the interaction of the above-mentioned multiple effects, firstly, the fixed block drives the heating furnace insulation shell to rotate the rotating shaft, which oscillates stably at multiple angles. Then, the support shaft drives the gravity rolling ball to roll irregularly in multiple directions inside the heating furnace. Finally, the concave grooved ring rotates vertically within the annular groove, which stably switches angles in multiple directions. In summary, the contact and heating uniformity between the raw materials is better, the heat conduction is more uniform, and the heating efficiency is greatly improved. Attached Figure Description

The center point of the driven shaft 37 and the center point of the rotating shaft 31 are on the same horizontal line.

[0035] The working principle of the ultrasonic etching isostatic pressing graphite strength enhancement calcination furnace of the present invention is as follows:

[0036] When external linkage is used, the ultrasonically etched isostatic graphite calcination raw material is transported into the calcination furnace 2 through the pouring hopper 29. The ultrasonically etched isostatic graphite calcination raw material is mainly aggregate, which is the main component. It is usually coke powder and quartz sand. They undergo complex chemical reactions at high temperature to form a graphite crystal structure. The binder is an auxiliary component, usually coal tar pitch. After the roasting furnace 2 is placed on the annular groove cover plate 20, the roasting furnace 2 inside the insulation shell 1 is heated to a high temperature by the heater 13. The drive reduction motor 41 is started, which drives the drive gear 40 to rotate 45 degrees clockwise. The drive gear 40 drives the drive chain 39 to rotate the driven gear 38. The driven gear 38 drives the driven shaft 37 to rotate 45 degrees clockwise inside the sleeve bracket 33. The driven shaft 37 drives the fixed block 30 to rotate the insulation shell 1 of the roasting furnace. The insulation shell 1 of the roasting furnace drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the angle sensor 32 to rotate and sense the angle. The sleeve bracket 33 ensures that the rotating shaft 31 rotates stably. At the same time, the insulation shell 1 of the roasting furnace drives the linkage slider 34 to rotate. The sliding block 34 slides inside the arc-shaped slide plate 35. Then, the drive reduction motor 41 is started to drive the drive gear 40 to reverse forty-five degrees. The drive gear 40 drives the drive chain 39 to rotate the driven gear 38. The driven gear 38 drives the driven rotating shaft 37 to rotate the fixed block 30. The fixed block 30 drives the heating shell 1 of the calcining furnace to rotate the rotating shaft 31. The rotating shaft 31 senses the angle sensor 32 output end. In this way, the drive reduction motor 41 switches back and forth, so that the calcining furnace 2 inside the heating shell 1 of the calcining furnace shakes back and forth. The ultrasonically etched isostatic graphite calcining material inside the calcining furnace 2 shakes and calcines fully, so that the ultrasonically etched isostatic graphite calcining material is in full contact, and the heat can be uniformly heated and calcined through multiple directions.

[0037] In multi-directional linkage, when the calcining furnace 2 tilts and sways back and forth, the fusion gravity ball 3 rolls on the outer wall of the support shaft 4 under the action of gravity. At the same time, the fusion gravity ball 3 drives the support shaft 4 to move, and the two limiting support rings 14 limit the fusion gravity ball 3 to the left and right. The support shaft 4 drives the concave sleeve frame 5 to move the support linkage shaft 6 left and right. At the same time, the support linkage shaft 6 moves up and down along the inner wall of the linkage sleeve ring 7 and the limiting ring 12. The support shaft 4 drives the linkage ring groove shaft 8 to rotate inside the support ring 9, and the connecting support block 10 supports the support ring 9. The entire fusion gravity ball 3 can drive the ultrasonically etched isostatic graphite calcining raw material to fully compress and contact inside the calcining furnace 2, and the connecting support block 10 drives the linkage rotating ring 11 to link the support block 1. 6. Rotation: Multiple linkage support blocks 16 drive the concave groove ring 17 to rotate and switch directions in the annular groove 15 inside the annular groove cover plate 20. The concave groove ring 17 drives the limiting shaft ring 18 to make multiple balls 19 roll inside the annular groove 15. Thus, the linkage support block 16 drives the concave groove ring 17 to rotate the connecting support block 10. The connecting support block 10 drives the support ring 9 to rotate the linkage ring groove shaft 8. The linkage ring groove shaft 8 drives the linkage sleeve ring 7 to rotate and switch angles. The entire support linkage shaft 6 drives the concave sleeve frame 5 to rotate the support shaft rod 4. The support shaft rod 4 drives the fusion gravity rolling ball 3 to roll irregularly in multiple directions inside the roasting furnace 2, achieving full rolling and extrusion at multiple angles inside the roasting furnace 2. The isostatic graphite roasting raw material etched by ultrasonic waves is fully extruded and contacted for roasting at multiple points.

[0038] The limiting rolling mechanism is achieved by the fixed support column 28 supporting the sleeve support block 27, which in turn supports the sleeve through hole block 21, which in turn supports the sleeve cylinder 22. The lower surface of the limiting ball 24 is pressed against the concave groove ring 17. The sleeve cylinder 22 provides vertical support to the support block 26, which in turn provides vertical support to the limiting block 25. The limiting block 25 limits the limiting ball 24. The limiting ball 24 rolls inside the limiting block 25 and the fitting shaft ring 23, ensuring that the concave groove ring 17 rotates vertically within the annular groove 15, thus stably achieving the rotation switching direction of the concave groove ring 17.
