Description

Technical Field

[0001] This invention belongs to the field of rotary kilns, specifically relating to a rotary kiln for zinc oxide solid powder. Background Technology

[0002] In the existing technology, the production of zinc oxide solid powder uses a precipitation method: zinc salts (such as zinc sulfate) are reacted with alkalis (such as sodium carbonate) to generate zinc carbonate or basic zinc carbonate precursors, which are then decomposed by high-temperature calcination in a rotary kiln to obtain zinc oxide. When calcining zinc oxide solid powder at high temperature, the material is often piled up in the kiln, and the heating area during high-temperature calcination is limited, which urgently needs to be improved.

[0003] The present invention seeks to mitigate or at least alleviate such problems or defects by providing new or otherwise improved rotary kilns. Summary of the Invention

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.

It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0057] In the embodiments, by Figure 1-8 A rotary kiln for zinc oxide solid powder is provided, wherein, Figure 1This is a schematic diagram of the overall structure of the rotary kiln for the zinc oxide solid powder of the present invention; Figure 2 This is a schematic diagram of the rotary kiln for zinc oxide solid powder from another perspective. Figure 3 This is a schematic diagram of the overall structure of the lifting component of the present invention; Figure 4 This is an exploded view of the lifting component of the present invention; Figure 5 This is a schematic diagram of the structure of the present invention when the column wheel and the follower wheel are separated; Figure 6 This is a schematic diagram of the structure of the rotary kiln and tamping component of the present invention when they are combined. Figure 7 This is a schematic diagram of the overall structure of the tamping component of the present invention; Figure 8 This is a schematic diagram of the overall structure of the tamping component of the present invention from another perspective. It includes: a housing 1 with an internal mounting cavity; a three-axis adjustment module 2 detachably mounted within the housing 1; a rotary kiln 3 detachably mounted within the housing 1, positioned below the three-axis adjustment module 2; a tamping component 4 consisting of a pressing section and a flipping section connected to the pressing section; and a lifting component 5 consisting of a trigger section and a lifting mechanism linked to the trigger section. The system consists of a trigger section connected to the housing 1 and the three-axis adjustment module 2, and a lifting section that can penetrate into the rotary kiln 3. When the output of the three-axis adjustment module 2 is output, it can force the trigger section to move, thereby driving the lifting section to move up and down within the rotary kiln 3 to lift and agitate the zinc oxide solid powder placed in the rotary kiln 3. When the lifting section acts on the pressing section, it can cause the pressing section to tend to expand towards the inner wall of the rotary kiln 3.

[0058] The overall concept of this invention is as follows: By using the tamping component 4, when the three-way trigger wheel 581 moves upward, it can compress the inclined surface at the bottom of the support arm 43, driving multiple support arms 43 to expand outward. Simultaneously, the holding arm 44 swings, and the elastic element 45 is compressed inward. On one hand, this pushes the crossbar 48 outward to push the tamping plate 481 to expand and push the material outward, thereby enhancing the material's fluidity within the rotary kiln 3, increasing the material's heating area, and accelerating the drying effect. On the other hand, the elastic element 45 flips, driving the slip ring 46 downward to drive the internal disc 491 to flip, thus flipping and lifting the material on the internal disc 491, further enhancing the material's fluidity and heating drying area. Thirdly, the lifting disc 582, which moves up and down multiple times, further agitates the material, enhancing its fluidity. The tamping component 5... When the output of the three-axis adjustment module 2 is output, it can drive the mounting plate 522 to move downward. After the mounting plate 522 moves downward, it can drive the ball bearings to move in the spiral groove, thereby driving the rotating shaft 52 and the column wheel 53 to rotate. After the column wheel 53 rotates, it can drive the ball bearings on the side rod 56 to slide through the inclined groove. At this time, the side rod 56 is lifted upward and the lifting shaft 58 moves upward, thereby moving the lifting plate 582 upward, which can lift the zinc oxide solid powder in the rotary kiln 3. When the ball bearings move into the vertical groove, the built-in spring 584, which is compressed, loses its restraint and rebounds, driving the lifting shaft 58 to move down to the initial position. After the ball bearings on the side rod 56 slide through the inclined groove, the side rod 56 can be driven to continue lifting the lifting shaft 58 upward, and the lifting plate 582 can be moved upward to lift the zinc oxide solid powder again. This lifting action can increase the heating area when the zinc oxide solid powder is dried in the rotary kiln 3.

[0059] Next, a more specific structure and construction of the tamping component 4 will be given for further explanation. The tamping component 4 has a pressing section including: an inner cylinder 41, which is detachably arranged inside the rotary kiln 3; a core column 42, which is detachably arranged on the inner cylinder 41; a support arm 43, on which two sets of clamping arms 44 are rotatably arranged, and both sets of clamping arms 44 are rotatably arranged on the core column 42; an elastic element 45, one end of which is slidably arranged on the support arm 43; and a slip ring 46, which is slidably arranged on the core column 42. The core column 42 is rotatably connected to the other end of the slip ring 46 and the elastic member 45; the tamping rod 47 is arranged on the side end of the slip ring 46; the tamping member 4 has a flipping section including: a bottom rod 49, which is detachably installed on the inner tube 41, and an inner plate 491 is rotatably arranged on the bottom rod 49; a telescopic member 492, which is detachably arranged on the inner tube 41 and the inner plate 491 respectively, a crossbar 48 is arranged on the support arm 43, and a tamping plate 481 is arranged on the crossbar 48;

[0060] Next, the overall operating principle and effect of the tamping component 4 will be further explained. When the three-way trigger wheel 581 is activated and moves upward, it can squeeze the inclined surface at the bottom of the support arm 43 to drive multiple support arms 43 to expand outward. At the same time, the holding arm 44 swings, and the elastic element 45 is compressed inward. On the one hand, it can push the crossbar 48 to push the tamping plate 481 outward to expand and push the material to enhance the fluidity of the material in the rotary kiln 3, increase the heating area of ​​the material, and accelerate the drying effect of the material. On the other hand, it can also drive the slip ring 46 to move downward by flipping the elastic element 45 to drive the inner plate 491 to flip and lift the material on the inner plate 491 to further enhance the fluidity of the material and increase the heating and drying area of ​​the material. Thirdly, the lifting plate 582, which moves up and down multiple times, can further agitate the material to enhance its fluidity.

[0061] Next, a more specific structure and construction of the elastic element 45 will be given for further explanation. The elastic element 45 includes: a lower adjusting rod, which is rotatably arranged on the slip ring 46, with a retaining ball at the free end of the lower adjusting rod and a spring on the lower adjusting rod; and an upper adjusting rod, which is rotatably arranged on the side of the support arm 43, with a rod cavity inside the upper adjusting rod that allows the lower adjusting rod to pass through, and a side cavity at the side end of the upper adjusting rod that allows the retaining ball to slide.

[0062] In some embodiments, the elastic element 45, on the one hand, reduces the impact force of the drive tri-directional trigger wheel 581 when pushing the support arm 43 to move laterally; on the other hand, the lower adjusting rod in the elastic element 45 slides in the upper adjusting rod and is limited by the spring, so that when the support arm 43 loses its compression, it can return to the initial position by the elastic force of the spring. The material is continuously pushed outward and flipped from bottom to top by the tamping plate 481 and the built-in disc 491, so as to increase the heating area of ​​the material in the rotary kiln 3 and enhance the heating and drying effect.

[0063] Next, a more specific structure and construction of the telescopic member 492 will be given for further explanation. The telescopic member 492 includes: a lower base, which is detachably mounted on the inner cylinder 41, and a lower base column is provided in the lower base, and a spring 2 is slidably arranged on the lower base column; and an upper base, which is detachably mounted on the inner plate 491, and an upper base column is provided in the upper base, and the upper base column can be passed through by the spring 2.

[0064] In some embodiments, more specifically, in order to enable the inner disc 491 to return to its initial position when the tamping rod 47 retracts, the second spring can be stretched when the right side of the inner disc 491 is pressed, and the second spring can return to its initial position when the tamping rod 47 retracts.

[0065] In some embodiments, more specifically, the bottom of the support arm 43 has a ramp that extends along the bottom of the support arm 43 toward the side of the support arm 43.

[0066] Next, a more specific structure and construction of the lifting component 5 will be given for further explanation. The lifting component 5 has the following trigger section: an outer disk 51, which is detachably mounted on the housing 1; a rotating shaft 52, which is rotatably arranged inside the outer disk 51, with a shaft sleeve 521 on the rotating shaft 52, and a spiral groove inside the shaft sleeve 521; a mounting plate 522, which is detachably mounted on the output end of the three-axis adjustment module 2, with two sets of balls that can move in the spiral groove inside the mounting plate 522; a roller 53, which is detachably mounted on one end of the rotating shaft 52; and a sleeve 54, which is detachably arranged inside the outer disk 51, with a spiral groove inside the sleeve 521. 4 has a follower wheel 55; the lifting member 5 has a lifting section including: a vertical plate 57, which is detachably installed on the rotary kiln 3, a lifting shaft 58 is slidably arranged in the vertical plate 57 and can be inserted into the rotary kiln 3, a three-way trigger wheel 581 and a lifting plate 582 are detachably installed on the lifting shaft 58; a side shaft 583, which is connected to the lifting shaft 58 through a short plate, a built-in spring 584 is slidably arranged on the side shaft 583, a side rod 56 is detachably installed at one end of the side shaft 583, and a roller that can slide in the column wheel 53 is detachably arranged at one end of the side rod 56;

[0067] Next, the overall operating principle and effect of the lifting component 5 will be further explained. When the output end of the three-axis adjustment module 2 is output, it can drive the mounting plate 522 to move downward. After the mounting plate 522 moves downward, it can drive the ball bearings to move in the spiral groove, thereby driving the rotating shaft 52 and the column wheel 53 to rotate. After the column wheel 53 rotates, it can drive the ball bearings on the side rod 56 to slide through the inclined groove. At this time, the side rod 56 is lifted upward, and the lifting shaft 58 moves upward, thereby moving the lifting plate 582 upward, which can adjust the rotary kiln. The zinc oxide solid powder in the rotary kiln 3 is lifted and raised. When the ball moves into the vertical groove, the built-in spring 584 is compressed and rebounds, driving the lifting shaft 58 to move down to the initial position. After the ball on the side rod 56 slides through the inclined groove, it can drive the side rod 56 to continue to lift the lifting shaft 58 and move it upward. This causes the lifting plate 582 to move upward again, lifting the zinc oxide solid powder again. This lifting and raising can increase the heating area when the zinc oxide solid powder is dried in the rotary kiln 3.

[0068] In some embodiments, more specifically, the column wheel 53 has a first inclined groove, a first vertical groove, a second inclined groove, and a second vertical groove sequentially formed on its outer circumference. When the column wheel 53 rotates, the ball bearings on the side rod 56 can slide sequentially through the first inclined groove, the first vertical groove, the second inclined groove, and the second vertical groove. A needle roller can also be detachably installed at the tail of the column wheel 53. A convex ring is provided at the top of the follower wheel 55, and two sets of grooves are provided on the convex ring. In the initial position, the lowest point of the groove abuts against the needle roller. When the column wheel 53 drives the needle roller to rotate, it can drive the needle roller to move along one set of grooves and move to the top of the convex ring, then to the other set of grooves, and continue to move to the top of the convex ring. In the initial state, the built-in spring 584 is located between the upright plate 57 and the side rod 56, and the first end of the built-in spring 584 abuts against the top of the upright plate 57, and the tail end of the built-in spring 584 abuts against the top of the side rod 56.

[0069] Next, a more specific structure and construction of the ventilation section of the lifting component 5 will be given for further explanation. The lifting component 5 also has a ventilation section, which includes: a piston cylinder 59, which is detachably installed in the sleeve 54. One end of the piston cylinder 59 is connected to the rotary kiln 3. A built-in spring 591 is provided in the piston cylinder 59; an extension tube 592, which is detachably installed in the body of the piston cylinder 59. A one-way air valve is provided in the extension tube 592. The piston cylinder 59 is composed of an outer cylinder body, a piston that slides in the cavity of the outer cylinder body, and a piston rod that is connected to the piston. The outer cylinder body is detachably installed in the sleeve 54. The piston rod can be passed through by the built-in spring 591. The top of the piston rod is in contact with the follower wheel 55.

[0070] Next, the working principle and effect of the ventilation section of the lifting component 5 will be further explained. When the column wheel 53 rotates, it drives the needle roller to rotate, causing the needle roller to move along one set of grooves and move to the top of the convex ring, then to another set of grooves, and continue to move to the top of the convex ring. It can first press down the piston rod to inject gas into the rotary kiln 3 through the piston cylinder 59, and then flow out through the hole reserved at the top of the rotary kiln 3. On the one hand, it can blow air into the raised material, which can improve the degree of dispersion between the materials and enhance the heating area of ​​the materials. On the other hand, with the repeated blowing and evacuation of the ventilation section, it can also promote the lifting effect of the built-in plate 491 on the material and promote the expansion and pushing effect of the tamping plate 481 on the material.

[0071] In summary, the tamping component 4, through its arrangement, serves several purposes. First, it pushes the crossbar 48 outward to push the tamping plate 481 to expand and push the material, thereby enhancing the material's fluidity within the rotary kiln 3, increasing the material's heating area, and accelerating the drying effect. Second, it drives the slip ring 46 downward through the rotation of the elastic element 45, causing the inner disc 491 to rotate and lift the material on the inner disc 491, further enhancing the material's fluidity and increasing its heating and drying area. Third, it allows the lifting disc 582, which moves up and down repeatedly, to further tamp the material. Another disturbance enhances the fluidity of the material. The lifting component 5 moves the lifting plate 582 upward again, lifting and raising the zinc oxide solid powder once more. This lifting and raising increases the heating area when the zinc oxide solid powder is dried in the rotary kiln 3. Firstly, it can aerate the raised material, increasing the degree of dispersion between materials and strengthening the heating area. Secondly, the repeated blowing and purging of the air in the ventilation section can further promote the lifting effect of the built-in plate 491 on the material and the expanding and pushing effect of the tamping plate 481 on the material.
