Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal hydrometallurgical technology, and in particular to a closed-type fire-resistant and explosion-proof zinc powder conveying device. Background Technology

[0002] Zinc oxide is an inorganic compound that is a white or pale yellow powder at room temperature. It is commonly known as zinc white, zinc oxide powder, zinc white powder, etc., and is widely used in the manufacture of plastics, silicate products, synthetic rubber, lubricating oil, smelting and paint coatings.

[0003] In the non-ferrous metal hydrometallurgical industry, zinc oxide is used as a raw material to extract substances such as fluorine and chlorine. During the smelting process, a conveying device is used to transport zinc powder, but the existing zinc powder conveying device has certain inconveniences in use.

[0004] First, existing conveying devices mostly use screw feeding, which easily leaves zinc powder residue on the inner wall of the conveying pipe. During bolt conveying, metal friction can easily generate sparks, which can cause the residual zinc powder to spontaneously combust and explode. Therefore, the safety during use is generally poor. In addition, existing conveying devices mostly use quantitative conveying, and the quantitative device has a fixed structure that cannot be adjusted, making it inconvenient to control the conveying volume.

[0005] Therefore, we propose a closed-loop, fire-resistant, and explosion-proof zinc powder conveying device. Utility Model Content

[0006] In view of the existing technology, most existing conveying devices use screw feeding, which easily leaves zinc powder residue on the inner wall of the conveying pipe. During bolt conveying, metal friction can easily generate sparks, which can cause the residual zinc powder to spontaneously combust and explode. The safety of these devices is generally poor. Furthermore, existing conveying devices are mostly used for quantitative conveying, and the quantitative device is a fixed structure that cannot be adjusted, making it difficult to control the conveying volume. Therefore, this utility model provides a closed-type fireproof and explosion-proof zinc powder conveying device.

[0007] The technical solution adopted by this utility model is: a closed-type fireproof and explosion-proof zinc powder conveying device, including a base plate, a feeding pipe, a feeding assembly and a hopper. The feeding assembly includes an outer frame, an inner frame, a tilting motor, a movable rod, a connecting spring and a hammer. The inner frame is movably connected to the middle of the outer frame. The tilting motor is fixedly installed on one side of the outer surface of the outer frame. The movable rods are all arranged at both ends of the inner frame. The connecting spring is arranged between the movable rod and the inner frame. The hammer is arranged on the outer surface of one end of the movable rod.

[0008] Furthermore, a blower is fixedly connected to the outer surface of one end of the feeding pipe, a sliding groove is provided in the middle of the base plate, a slider is provided in the middle of the sliding groove, a limit spring is provided between the slider and the sliding groove, a cylinder is fixedly connected to the upper outer surface of the slider, and a vibration motor is provided on the outer wall of the cylinder.

[0009] Furthermore, a metering bin is fixedly connected to the lower outer surface of the hopper, a feeding pipe is fixedly connected to the outer wall of the metering bin, a sealing cover is provided on the upper outer surface of the hopper, and an end plate is provided on one end of the outer surface of the metering bin.

[0010] Furthermore, a drive motor is fixedly connected to the outer surface of the other end of the metering chamber, and a rotating body is movably connected to the middle of the metering chamber. A central groove and a metering groove are provided in the middle of the rotating body. The metering groove is located around the central groove. A limit plate is provided in the middle of the metering groove, and a lead screw is provided in the middle of the central groove.

[0011] Furthermore, the output end of the flipping motor is connected to one outer surface of the built-in frame, and the movable rod is movably connected to the connecting spring through the connecting spring.

[0012] Furthermore, the output end of the drive motor is connected to the outer surface of one end of the rotating body, and the rotating body is integrally formed with the central groove and the metering groove.

[0013] Furthermore, the lead screw extends through the middle of the metering groove, and one end of the lead screw's outer surface is connected to one end of the limiting plate's outer surface.

[0014] The beneficial effects of this utility model are:

[0015] 1. In this utility model, the feeding component can be fixedly installed on the feeding pipe through the built-in frame. After the material is conveyed, the flipping motor can drive the built-in frame to rotate, causing the built-in frame to tilt the feeding pipe, which can make the zinc powder remaining on the inner wall of the feeding pipe slide off. At the same time, the vibration motor can be started. Under the action of the vibration motor, the movable rod can be shaken by the connecting spring. While shaking, the hammer head can strike the outer wall of the feeding pipe, which can effectively remove the zinc powder remaining on the inner wall of the feeding pipe and avoid the situation of zinc powder spontaneous combustion and explosion. It is highly safe to use.

[0016] 2. In this utility model, the quantitative hopper is tightly fitted with the internal rotating body during use. The rotating body can receive zinc powder conveyed by the hopper through the quantitative trough and complete quantitative conveying through the quantitative trough. Then, the screw can be rotated as needed to move the limiting plate in the quantitative trough, thereby adjusting the space in the quantitative trough and thus adjusting the feeding amount of the quantitative trough. It is also convenient to alternately convey different amounts of zinc powder, making it more convenient to use. Attached Figure Description

[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a closed-type fire-resistant and explosion-proof zinc powder conveying device.

[0026] The specific technical solution includes a base plate 1, a feeding pipe 2, a feeding assembly 3, and a hopper 4. The feeding assembly 3 includes an outer frame 31, an inner frame 32, a tilting motor 33, a movable rod 34, a connecting spring 35, and a hammer 36. The inner frame 32 is movably connected to the middle of the outer frame 31. The tilting motor 33 is fixedly installed on one side of the outer surface of the outer frame 31. The movable rods 34 are all located at both ends of the inner frame 32. The connecting spring 35 is located between the movable rod 34 and the inner frame 32. The hammer 36 is located on the outer surface of one end of the movable rod 34. The feeding assembly 3 can be used... The feeding pipe 2 is fixedly installed by the built-in frame 32. After the material is conveyed, the tilting motor 33 can drive the built-in frame 32 to rotate, causing the built-in frame 32 to tilt the feeding pipe 2, which can make the zinc powder remaining on the inner wall of the feeding pipe 2 slide off. At the same time, the vibration motor 10 can be started. Under the action of the vibration motor 10, the movable rod 34 can be shaken by the connecting spring 35. While shaking, the hammer head 36 can strike the outer wall of the feeding pipe 2, which can effectively remove the zinc powder remaining on the inner wall of the feeding pipe 2 and avoid the situation of zinc powder spontaneously combusting and exploding. It is highly safe during use.

[0027] Furthermore, the output end of the flip motor 33 is connected to one side of the outer surface of the built-in frame 32, and the movable rod 34 is movably connected to the connecting spring 35 through the connecting spring 35. The flip motor 33 is mainly used to drive the built-in frame 32 to flip, which can make the built-in frame 32 drive the feeding tube 2 to tilt, so as to facilitate feeding.

[0028] Reference Figure 1 , Figure 3 and Figure 4As shown, a blower 5 is fixedly connected to the outer surface of one end of the feeding pipe 2. A chute 6 is provided in the middle of the base plate 1, and a slider 7 is provided in the middle of the chute 6. A limit spring 8 is provided between the slider 7 and the chute 6. A cylinder 9 is fixedly connected to the outer surface of the upper end of the slider 7, and a vibration motor 10 is provided on the outer wall of the cylinder 9. A metering chamber 11 is fixedly connected to the outer surface of the lower end of the hopper 4, and a feeding pipe 12 is fixedly connected to the outer wall of the metering chamber 11. A sealing cover 13 is provided on the outer surface of the upper end of the hopper 4. An end plate 14 is provided on the outer surface of one end of the metering chamber 11, and a drive motor 15 is fixedly connected to the outer surface of the other end of the metering chamber 11. A rotating body 16 is movably connected to the middle of the metering chamber 11. A central groove 17 and a metering groove 18 are provided in the middle of the rotating body 16, and the metering groove 18 is located in the central groove. A limiting plate 19 is provided in the middle of the metering trough 18 around the perimeter of 17, and a lead screw 20 is provided in the middle of the central trough 17. When in use, the vibration motor 10 can vibrate the cylinder 9, so that the vibration force of the cylinder 9 can be transmitted to the slider 7. The slider 7 can reciprocate in the slide groove 6 through the limiting spring 8. When in use, the metering bin 11 is in close contact with the internal rotating body 16. The rotating body 16 can receive the zinc powder conveyed by the hopper 4 through the metering trough 18, and the metering can be completed through the metering trough 18. Then, the lead screw 20 can be rotated as needed, so that the lead screw 20 drives the limiting plate 19 to move in the metering trough 18, thereby adjusting the space in the metering trough 18, thereby adjusting the feeding amount of the metering trough 18, and facilitating the alternating conveying of different amounts of zinc powder, which is more convenient to use.

[0029] Furthermore, the output end of the drive motor 15 is connected to the outer surface of one end of the rotating body 16. The rotating body 16 is integrally formed with the central groove 17 and the metering groove 18. When in use, the drive motor 15 is mainly used to drive the rotating body 16 to rotate, so that the rotating body 16 receives zinc powder through the metering groove 18. The central groove 17 facilitates the adjustment of the capacity in the metering groove 18 by rotating the lead screw 20.

[0030] Furthermore, the lead screw 20 extends through the middle of the metering groove 18, and one end of the outer surface of the lead screw 20 is connected to one end of the outer surface of the limiting plate 19. The lead screw 20 is mainly used to drive the limiting plate 19 to move within the metering groove 18, thereby adjusting the space within the metering groove 18 and thus adjusting the feeding amount of the metering groove 18.

[0031] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0032] During operation, zinc powder enters the metering hopper 11 from the hopper 4. The drive motor 15 drives the rotating body 16 to rotate, causing it to receive the zinc powder through the metering trough 18 and rotate. When the zinc powder rotates to the discharge pipe 12, it enters the feeding pipe 2. At this point, the blower 5 can be started to blow the zinc powder. During zinc powder conveying, the height of the cylinder 9 can be adjusted according to the height of the processing equipment. The cylinder 9 can drive the feeding pipe 2 to rise and fall. When the conveying volume needs to be adjusted, the end plate 14 can be opened as needed, and then the lead screw 20 can be rotated in the central slot 17. This causes the lead screw 20 to move the limiting plate 19 within the metering trough 18, adjusting the space within the metering trough 18 and thus the feeding volume. This facilitates [further adjustments]. Alternating the feeding of different amounts of zinc powder makes it convenient to use. When the feeding is completed, the tilting motor 33 can be started to drive the built-in frame 32 to rotate, causing the built-in frame 32 to tilt the feeding pipe 2, allowing the zinc powder remaining on the inner wall of the feeding pipe 2 to slide off. At the same time, the vibration motor 10 can be started, which vibrates the cylinder 9. When the cylinder 9 is vibrated, the vibration force is transmitted to the slider 7. The slider 7 can reciprocate in the slide groove 6 through the limit spring 8. Under the action of the vibration motor 10, the movable rod 34 can shake through the connecting spring 35. While shaking, the hammer head 36 can strike the outer wall of the feeding pipe 2, which can effectively remove the zinc powder remaining on the inner wall of the feeding pipe 2 and avoid the situation of zinc powder spontaneous combustion and explosion. It is safe to use.
