Description

Technical Field

[0001] This invention belongs to the field of antimony trioxide quantitative conveying technology, specifically an antimony trioxide quantitative conveying device. Background Technology

[0002] Flame-retardant coatings applied to equipment or buildings often use antimony trioxide. The production of antimony trioxide requires multiple processes, and a conveying mechanism is needed to reload the material when connecting two processes. Currently, the commonly used conveying mechanism is the screw conveyor. The screw conveyor not only has high conveying efficiency, but also provides a fully sealed conveying of antimony trioxide, preventing powdered antimony trioxide from spilling into the surrounding environment.

[0003] Patent CN213678561U discloses a screw conveyor for antimony trioxide production, including a base. A groove is reserved on one side of the top of the base, and a first support rod is fixed on the side of the top of the base away from the groove. The top of the first support rod is hinged to the main body of the screw conveyor mechanism, and a second support rod is installed at the edge of the top of the base near the groove. This screw conveyor for antimony trioxide production, through the sliding connection between the movable plate and the groove, and the elasticity of the first spring, allows the movable plate to drive the casters to extend from the groove and lift the equipment when there is no raw material in the main body of the screw conveyor mechanism, making it convenient for operators to move the device using the casters.

[0004] In the above-mentioned scheme, antimony trioxide is conveyed by rotating the screw conveyor shaft inside the screw conveyor. During the processing of antimony trioxide, the amount of antimony trioxide added in each process is fixed. However, the above-mentioned device can only control the amount of antimony trioxide conveyed by controlling the number of rotations of the screw conveyor shaft. However, the controlled amount of conveying has a large error, which affects the quality of subsequent processing of antimony trioxide. Therefore, the present invention provides a quantitative conveying device for antimony trioxide. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a quantitative conveying device for antimony trioxide, including a conveying pipe, a spiral conveying shaft rotatably installed inside the conveying pipe, a hopper at the lower end of the conveying pipe, a connecting pipe at the upper end of the conveying pipe, the connecting pipe extending into the storage cavity inside the quantitative box, a vibration motor fixedly installed on the top of the quantitative box, a feeding mechanism inside the quantitative box, the feeding mechanism including a quantitative tube, two sets of rubber sealing rings fixedly installed inside the quantitative box, the quantitative tube movably inserting into the rubber sealing rings, a fixed sleeve fixedly fitted at the lower end of the quantitative tube, a screw screwed to the fixed sleeve, the screw rotatably installed inside the quantitative box, a switch plate movably inserted inside the quantitative tube, a round opening on the switch plate, a first guide groove on both sides inside the quantitative box, a shaft welded to both sides of the switch plate, the end of the shaft located in the first guide groove, the first guide groove being composed of a vertical groove and an inclined groove;

[0007] The switch board can automatically cut off and open the internal flow channel of the metering tube. The amount of antimony trioxide that can be held in the metering tube each time is fixed, so that the amount of antimony trioxide added from the metering tube to the processing equipment is fixed, thereby ensuring the accuracy of the amount of antimony trioxide added to the processing equipment.

[0008] Preferably, the quantitative tube includes a tube body, a switch plate movably inserted into the tube body, a rubber sealing ring movably inserted into the tube body, a screw-in tube rotatably installed on one side of the upper end of the tube body, a movable sleeve, the movable sleeve being located at the upper end of the tube body and the screw-in tube being fixedly connected to the movable sleeve, a movable rod inserted into the screw-in tube, a movable frame fixedly connected to the lower end of the movable rod, a spring located below the movable frame, a rectangular groove provided inside the quantitative tube, the movable frame being slidably connected to the rectangular groove, the spring being located inside the rectangular groove, two sets of second guide grooves being opened on the inner ring of the screw-in tube, two sets of convex shafts being fixedly installed on the outer ring of the movable rod, the convex shafts being located inside the second straight groove, the second guide groove being composed of a first straight groove, a spiral groove, and a second straight groove, the length of the first straight groove being greater than the length of the first straight groove, driving the convex shaft along the spiral groove to rotate the screw-in tube, and a baffle for pushing the movable rod being provided in the storage cavity;

[0009] By setting up components such as the movable sleeve and tube body, the antimony trioxide accumulated at the top of the metering tube is removed, thereby ensuring that the amount of antimony trioxide remaining in the metering tube is constant, further improving the accuracy of the amount of antimony trioxide added to the processing equipment.

[0010] Preferably, the metering tube also includes a gear, several sets of teeth on the gear meshing movable frame, a shaped disc fixedly mounted on the end of the gear, a receiving frame, the receiving frame located above the shaped disc, a connecting rod fixedly connected to the receiving frame, an arc plate fixedly connected to the connecting rod, an actuating rod, the lower end of the actuating rod abutting against the upper end face of the arc plate, a limiting sleeve fixedly connected to the upper end of the actuating rod, an annular groove opened on the movable sleeve, the limiting sleeve located in the annular groove, the gear rotatably mounted in the rectangular groove, the receiving frame slidably mounted in the rectangular groove, a concave surface provided on the outer ring of the shaped disc, a roller rotatably mounted on the receiving frame, the roller fitting against the outer ring of the shaped disc, an arc groove opened on one side of the upper end of the tube body, an arc plate located in the arc groove, and the arc plate slidably connected to the arc groove;

[0011] When the movable sleeve rotates rapidly, the trigger rod moves along the arc groove, and the limiting sleeve pulls the antimony trioxide accumulated on the movable sleeve. This not only prevents antimony trioxide from scattering and inertial stagnation, but also increases the rate at which the entire device adds antimony trioxide to the processing equipment.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. The switch board can automatically cut off and open the internal flow channel of the metering tube. The amount of antimony trioxide that can be held in the metering tube each time is fixed, so that the amount of antimony trioxide added from the metering tube to the processing equipment is fixed, thereby ensuring the accuracy of the amount of antimony trioxide added to the processing equipment.

[0014] 2. As the metering tube continues to move upward, the movable rod is pushed and squeezed by the baffle, causing the movable rod and the movable frame to move downward. At the same time, the spring is compressed by the movable frame. The convex shaft on the movable rod first slides downward along the first straight groove until it slides into the spiral groove. Under the guidance of the spiral groove, the screw tube rotates, and the screw tube drives the movable sleeve to rotate slowly together. As the movable sleeve rotates, the antimony trioxide located in the movable sleeve and accumulated on the movable sleeve begins to detach from the antimony trioxide in the tube. Under the action of gravity, this part of the antimony trioxide will fall back to the bottom of the storage chamber. At this time, the amount of antimony trioxide in the tube is constant. During the process of opening the internal flow channel of the tube, the convex shaft slides downward along the second straight groove, and at the same time, the antimony trioxide in the metering tube flows into the processing equipment, thereby ensuring that the amount of antimony trioxide remaining in the metering tube is constant, further improving the accuracy of the amount of antimony trioxide added to the processing equipment.

[0015] 3. As the convex shaft on the movable rod slides downward along the first straight groove, the teeth on the movable frame drive the gears and the shaped disc to rotate. As the shaped disc rotates, the rollers roll along the concave surface of the shaped disc, and the concave surface pushes the rollers upward, causing the receiving frame, connecting rod, and arc plate to move upward. At the same time, the arc plate pushes the trigger rod and the limiting sleeve to move upward, causing the limiting sleeve to extend out of the annular groove on the movable sleeve head. When the movable sleeve head rotates rapidly, the limiting sleeve will carry the antimony trioxide accumulated on the movable sleeve head, which not only avoids the spillage of antimony trioxide and the occurrence of inertial stagnation, but also increases the rate at which the entire device adds antimony trioxide to the processing equipment.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figures 1 to 4 As shown in the embodiment of the present invention, a quantitative conveying device for antimony trioxide includes a conveying pipe 1, a spiral conveying shaft 2 rotatably installed inside the conveying pipe 1, a hopper 3 at the lower end of the conveying pipe 1, and a connecting pipe 4 at the upper end of the conveying pipe 1. The connecting pipe 4 extends into the storage chamber 501 inside the quantitative tank 5. A vibration motor 6 is fixedly installed on the top of the quantitative tank 5. A feeding mechanism 7 is provided inside the quantitative tank 5, and the feeding mechanism 7 includes a quantitative tube 701. Two sets of rubber sealing rings 502 are fixedly installed inside the quantitative tank 5, and the quantitative tube 701 is movably inserted into the rubber sealing rings. 502, a fixed sleeve 702 is fixedly fitted at the lower end of the metering tube 701, a screw 703 is screwed onto the fixed sleeve 702, the screw 703 is rotatably installed in the metering box 5, a switch plate 704 is movably inserted into the metering tube 701, the switch plate 704 has a round opening 7041, the metering box 5 has a first guide groove 503 on both sides, the switch plate 704 has a shaft 7042 welded on both sides, the end of the shaft 7042 is located in the first guide groove 503, the first guide groove 503 is composed of a vertical groove 5031 and an oblique groove 5032.

[0030] Specifically, the lower end of the metering box 5 is fixedly installed at the feed inlet of the processing equipment, and the lower end of the metering tube 701 extends into the interior of the processing equipment. In the initial state, the upper end of the metering tube 701 is located at the bottom of the storage chamber 501, and the internal flow channel of the metering tube 701 is cut off by the switch plate 704. When it is necessary to add antimony trioxide into the processing equipment, the raw material antimony trioxide is poured into the hopper 3, and then the screw conveyor shaft 2 is driven to rotate by the motor. At the same time, the vibration motor 6 is started. As the screw conveyor shaft 2 rotates, the antimony trioxide in the hopper 3 is conveyed to the connecting pipe 4, and the antimony trioxide is conveyed through the connecting pipe 4. The antimony trioxide flows into the storage chamber 501 through pipe 4. As the amount of antimony trioxide in the storage chamber 501 increases, under the vibration of the vibrating motor 6, the antimony trioxide in the storage chamber 501 will flow into the metering tube 701 until the metering tube 701 is full of antimony trioxide. Then, the rotation of the screw conveyor shaft 2 stops. The amount of antimony trioxide discharged into the storage chamber 501 through the connecting pipe 4 is greater than the amount of antimony trioxide that fills the metering tube 701. Then, the screw 703 is driven to rotate by another set of motors. As the screw 703 rotates, the fixed sleeve 702, together with the metering tube 701 and the switch plate 704, moves upward. At this time, the switch is turned on. The end of shaft 7042 on the switch plate 704 slides upward along the vertical groove 5031 until shaft 7042 is located at the intersection of the vertical groove 5031 and the inclined groove 5032, and the upper end of the metering tube 701 disengages from the antimony trioxide in the storage chamber 501. Continuing to drive the metering tube 701 upward, shaft 7042 slides along the inclined groove 5032. Guided by the inclined groove 5032, shaft 7042 drives the switch plate 704 to move away from the screw 703. The circular opening 7041 on the switch plate 704 gradually enters the metering tube 701. The internal flow channel of metering tube 701 is gradually opened until all the antimony trioxide in the metering tube 701 flows into the processing equipment. Then, metering tube 701 and switch plate 704 are returned to their initial state. When raw materials are added to the processing equipment again, the above operation is repeated. Compared with the prior art, switch plate 704 can automatically cut off and open the internal flow channel of metering tube 701. The amount of antimony trioxide that can be held in metering tube 701 each time is fixed, so the amount of antimony trioxide added from metering tube 701 to the processing equipment is fixed, thereby ensuring the accuracy of the amount of antimony trioxide added to the processing equipment.

[0031] like Figures 4 to 6As shown, the metering tube 701 includes a tube body 7011, a switch plate 704 movably inserted into the tube body 7011, a rubber sealing ring 502 movably inserted into the tube body 7011, a screw-in connector 7012 rotatably installed on one side of the upper end of the tube body 7011, a movable sleeve 7013 located at the upper end of the tube body 7011, and the screw-in connector 7012 fixedly connected to the movable sleeve 7013, a movable rod 7014 inserted into the screw-in connector 7012, a movable frame 7015 fixedly connected to the lower end of the movable rod 7014, a spring 7016 disposed below the movable frame 7015, and a rectangular groove 11 provided inside the metering tube 701. 1. The movable frame 7015 is slidably connected to the rectangular groove 111. The spring 7016 is located in the rectangular groove 111. Two sets of second guide grooves 121 are opened on the inner ring of the screw tube 7012. Two sets of convex shafts 141 are fixedly installed on the outer ring of the movable rod 7014. The convex shafts 141 are located in the second straight groove 13. The second guide groove 121 is composed of a first straight groove 11, a spiral groove 12, and a second straight groove 13. The length of the first straight groove 11 is greater than the length of the first straight groove 13. The convex shafts 141 are driven along the spiral groove 12 to make the screw tube 7012 rotate. The storage cavity 501 is provided with a baffle 504 for pushing the movable rod 7014.

[0032] Specifically, after the aforementioned metering tube 701 is filled with antimony trioxide, it will move upwards until its upper end is away from the antimony trioxide in the storage chamber 501. During this process, when the upper end of the metering tube 701 detaches from the antimony trioxide in the storage chamber 501, antimony trioxide will accumulate at the upper end of the metering tube 701. The amount of antimony trioxide accumulated at the upper end of the metering tube 701 is random and uncontrollable, resulting in a slight error in the amount of antimony trioxide fed into the processing equipment each time the metering tube 701 is used. Therefore, during the upward movement of the metering tube 701, when the movable rod on the metering tube 701... When 7014 contacts the baffle 504 inside the storage cavity 501, the movable sleeve 7013 on the metering tube 701 disengages from the antimony trioxide inside the storage cavity 501. As the metering tube 701 continues to move upward, the movable rod 7014 is pushed and squeezed by the baffle 504, causing the movable rod 7014 and the movable frame 7015 to move downward. The movable rod 7014 and the movable frame 7015 slide along the inner cavity of the screw-in tube 7012 and the rectangular groove 111, respectively. At the same time, the spring 7016 is compressed by the movable frame 7015. The convex shaft 141 on the movable rod 7014 first slides downward along the first straight groove 11 until the convex shaft 141 slides downward. Shaft 141 slides into the spiral groove 12, causing the metering tube 701 to slowly move upward. Guided by the spiral groove 12, the screw tube 7012 rotates, causing the movable sleeve 7013 to rotate slowly as well. As the movable sleeve 7013 rotates, the antimony trioxide located inside and accumulated on the movable sleeve 7013 begins to detach from the antimony trioxide in the tube body 7011. Under the influence of gravity, this portion of antimony trioxide falls back to the bottom of the storage chamber 501. At this point, the amount of antimony trioxide in the tube body 7011 is constant. The metering tube 701 continues to move upward... 1. Moving upwards, at this time, the end of shaft 7042 on switch plate 704 is located at the intersection of vertical groove 5031 and inclined groove 5032. During the process of opening the internal flow channel of tube body 7011, convex shaft 141 slides downwards along the second straight groove 13. At the same time, antimony trioxide in quantitative tube 701 flows into processing equipment. Through the setting of components such as movable sleeve 7013 and tube body 7011, the antimony trioxide accumulated at the upper end of quantitative tube 701 is removed, thereby ensuring that the amount of antimony trioxide remaining in quantitative tube 701 is constant, further improving the accuracy of the amount of antimony trioxide added to processing equipment.

[0033] Example 2

[0034] like Figures 6 to 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the metering tube 701 further includes a gear 7017, the gear 7017 meshing with a plurality of sets of teeth provided on the movable frame 7015, a shaped disc 7018 fixedly fitted on the end of the gear 7017, a receiving frame 7019, the receiving frame 7019 being located above the shaped disc 7018, a connecting rod 7021 fixedly connected to the receiving frame 7019, an arc-shaped plate 7022 fixedly connected to the connecting rod 7021, an actuating rod 7023, the lower end of the actuating rod 7023 abutting against the upper end surface of the arc-shaped plate 7022, and the upper end of the actuating rod 7023 being fixedly connected. The limiting sleeve 7024 has an annular groove 131 on the movable sleeve head 7013, and the limiting sleeve 7024 is located in the annular groove 131. The gear 7017 is rotatably installed in the rectangular groove 111, and the receiving frame 7019 is slidably installed in the rectangular groove 111. The outer ring of the irregular disc 7018 is provided with a concave surface 181, and the receiving frame 7019 is rotatably installed with a roller 7020. The roller 7020 fits against the outer ring of the irregular disc 7018. An arc groove 112 is provided on one side of the upper end of the tube body 7011, and an arc plate 7022 is located in the arc groove 112 and is slidably connected to the arc groove 112.

[0035] Specifically, the axis of the arc-shaped groove 112 is collinear with the axis of the screw-in connector 7012. The screw-in connector 7012 drives the movable sleeve 7013 to rotate slowly, removing the antimony trioxide accumulated at the upper end of the metering tube 701. During this process, the movable sleeve 7013 cannot rotate rapidly. If it rotates rapidly, the movable sleeve 7013 can move the antimony trioxide inside it, but most of the antimony trioxide accumulated on the movable sleeve 7013 may be scattered as the movable sleeve 7013 moves. A small amount of antimony trioxide will remain in its original position due to inertia. The antimony trioxide remaining in its original position... Antimony dioxide will fall to the upper end of the tube body 7011, and the antimony trioxide that is scattered will also fall back to the upper end of the tube body 7011, resulting in an inconsistent amount of antimony trioxide in the processing equipment flowing through the tube body 7011. However, the slow rotation of the movable sleeve 7013 will affect the rate at which antimony trioxide is added to the processing equipment. Therefore, when the movable rod 7014 and the movable frame 7015 move downwards, during the process of the convex shaft 141 on the movable rod 7014 sliding downwards along the first straight groove 11, the teeth on the movable frame 7015 drive the gear 7017 and the shaped disc 701. 8. As the shaped disc 7018 rotates, the roller 7020 rolls along the concave surface 181 on the shaped disc 7018. The concave surface 181 pushes the roller 7020 upward, causing the receiving frame 7019, along with the connecting rod 7021 and the arc plate 7022, to move upward. At the same time, the arc plate 7022 pushes the actuating rod 7023, along with the limiting sleeve 7024, to move upward, causing the limiting sleeve 7024 to extend out of the annular groove 131 on the movable sleeve head 7013 until the roller 7020 disengages from the concave surface 181. At this time, the convex shaft 141 is located at the intersection of the first straight groove 11 and the spiral groove 12. As the convex shaft 141 moves along... During the sliding process of the spiral groove 12 and the second straight groove 13, the roller 7020 rolls along the outer arc surface of the irregular disc 7018. Since the limiting sleeve 7024 protrudes from the movable sleeve 7013, the antimony trioxide accumulated on the movable sleeve 7013 is limited by the limiting sleeve 7024. When the movable sleeve 7013 rotates rapidly, the trigger rod 7023 will move along the arc groove 112, and the limiting sleeve 7024 will drive the antimony trioxide accumulated on the movable sleeve 7013. This not only avoids the spillage of antimony trioxide and the occurrence of inertial stagnation, but also increases the rate at which the entire device adds antimony trioxide to the processing equipment.

[0036] Working Principle: Antimony trioxide is poured into hopper 3, and then the screw conveyor shaft 2 is driven to rotate by a motor. Simultaneously, the vibration motor 6 is activated. As the screw conveyor shaft 2 rotates, the antimony trioxide in hopper 3 is conveyed to the connecting pipe 4, and then flows into storage chamber 501 through the connecting pipe 4. As the amount of antimony trioxide in storage chamber 501 increases, under the vibration of the vibration motor 6, the antimony trioxide in storage chamber 501 flows into metering tube 701 until metering tube 701 is full. Then, the screw conveyor shaft 2 stops rotating. The amount of antimony trioxide discharged into storage chamber 501 through connecting pipe 4 is greater than the amount of antimony trioxide in metering tube 701. Then, another set of motors drives screw 703 to rotate. As screw 703 rotates, fixed sleeve 702, along with metering tube 701 and switch plate 704, moves upward. At this time, the end of shaft 7042 on switch plate 704 slides upward along vertical groove 5031 until shaft 7042 is located at the intersection of vertical groove 5031 and inclined groove 5032, and the upper end of metering tube 701 disengages from antimony trioxide in storage chamber 501. Continue to drive metering tube 701 to move upward, shaft 7042 will slide along inclined groove 5032. Under the guidance of inclined groove 5032, shaft 7042 drives switch plate 704 to move away from screw 703. The round opening 7041 on switch plate 704 will gradually enter metering tube 701, and the internal flow channel of metering tube 701 will be gradually opened until all antimony trioxide in metering tube 701 flows into processing equipment. Then, metering tube 701 and switch plate 704 return to the initial state. When adding raw materials to processing equipment again, repeat the above operation.

[0037] During the upward movement of the metering tube 701, when the movable rod 7014 on the metering tube 701 contacts the baffle 504 inside the storage cavity 501, the movable sleeve 7013 on the metering tube 701 disengages from the antimony trioxide inside the storage cavity 501. As the metering tube 701 continues to move upward, the movable rod 7014 is pushed and squeezed by the baffle 504, causing the movable rod 7014 and the movable frame 7015 to move downward. The movable rod 7014 and the movable frame 7015 slide along the inner cavity of the spiral tube 7012 and the rectangular groove 111, respectively. At the same time, the spring 7016 is compressed by the movable frame 7015. The convex shaft 141 on the movable rod 7014 first slides downward along the first straight groove 11 until the convex shaft 141 slides into the spiral groove 12. At this time, the metering tube 701 moves upward slowly under the guidance of the spiral groove 12. The rotating tube 7012 rotates, causing the movable sleeve 7013 to rotate slowly. As the movable sleeve 7013 rotates, the antimony trioxide located inside and accumulated on the movable sleeve 7013 begins to detach from the antimony trioxide in the tube 7011. Under the action of gravity, this part of the antimony trioxide falls back to the bottom of the storage chamber 501. At this time, the amount of antimony trioxide in the tube 7011 is constant. The metering tube 701 continues to move upward. At this time, the end of the shaft 7042 on the switch plate 704 is located at the intersection of the vertical groove 5031 and the inclined groove 5032. During the process of the internal flow channel of the tube 7011 being opened, the convex shaft 141 slides downward along the second straight groove 13, and at the same time, the antimony trioxide in the metering tube 701 flows into the processing equipment.

[0038] As the convex shaft 141 on the movable rod 7014 slides downward along the first straight groove 11, the teeth on the movable frame 7015 drive the gear 7017 to rotate along with the shaped disk 7018. As the shaped disk 7018 rotates, the roller 7020 rolls along the concave surface 181 on the shaped disk 7018, and the concave surface 181 pushes the roller 7020 upward, causing the receiving frame 7019, together with the connecting rod 7021 and the arc plate 7022, to move upward. At the same time, the arc plate 7022 pushes the actuating rod 7023, together with the limiting sleeve 7024, to move upward, causing the limiting sleeve 7024 to extend from the annular groove 131 on the movable sleeve head 7013. The roller 7020 is pulled out until it disengages from the concave surface 181. At this time, the convex shaft 141 is located at the intersection of the first straight groove 11 and the spiral groove 12. During the sliding process of the convex shaft 141 along the spiral groove 12 and the second straight groove 13, the roller 7020 rolls along the outer arc surface of the irregular disc 7018. Since the limiting sleeve 7024 protrudes from the movable sleeve 7013, the antimony trioxide accumulated on the movable sleeve 7013 is limited by the limiting sleeve 7024. When the movable sleeve 7013 rotates rapidly, the trigger rod 7023 will move along the arc groove 112, and the limiting sleeve 7024 will drive the antimony trioxide accumulated on the movable sleeve 7013.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. 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 illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
