Description
Technical Field
[0001] This utility model relates to the field of calcium hydroxide air classification technology, and in particular to a calcium hydroxide air classification device. Background Technology
[0002] The production processes of calcium hydroxide can be divided into two main categories: wet process and dry process. In the dry process, air classification equipment plays a key role. It uses air power to separate calcium hydroxide powder from impurities, thereby improving the purity and fineness of the product.
[0003] In the existing technology for calcium hydroxide sorting, calcium hydroxide needs to be fed into the equipment through a feed frame for grinding and air classification. However, calcium hydroxide in the feed frame is prone to enter the equipment all at once, which causes calcium hydroxide to accumulate and affect the grinding and air classification of calcium hydroxide. Utility Model Content
[0004] This utility model proposes a calcium hydroxide air separation device to overcome the shortcomings of the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a calcium hydroxide air classifier, comprising a shell, which is placed on the ground to provide support for the whole, a feeding frame installed on the top of the shell, wherein a conveying device is provided inside the feeding frame, wherein the conveying device can disperse calcium hydroxide into the interior of the shell, a grinding roller is installed inside the shell, wherein a plurality of protrusions are uniformly fixedly connected to the arc surface of the grinding roller, a motor is installed on one side of the shell, wherein the motor can drive the grinding roller to rotate by means of a reducer, a discharge channel is installed inside the shell, wherein the discharge channel is located directly below the grinding roller, a discharge pipe is installed at the bottom of the shell, wherein the discharge pipe is connected to the discharge channel, and a high-pressure air pump is installed inside the shell, wherein the input end of the high-pressure air pump is connected to the discharge channel by means of a pipe, and the output end of the high-pressure air pump is fixedly connected to a discharge pipe, wherein the other end of the discharge pipe is located outside the shell.
[0006] The effect achieved by the above components is as follows: when calcium hydroxide needs to be air-separated, the worker feeds the calcium hydroxide into the inside of the feed frame. The conveying device disperses the calcium hydroxide into the inside of the shell. The motor is turned on, and the motor drives the grinding roller to rotate. The grinding roller grinds and crushes the calcium hydroxide. The ground calcium hydroxide enters the inside of the feeding channel. At this time, the high-pressure air pump is started. The high-pressure air pump generates negative pressure, so that the calcium hydroxide powder is absorbed into the discharge pipe and discharged to the outside of the shell when it falls. Meanwhile, the impurities in the calcium hydroxide are discharged through the discharge pipe.
[0007] Preferably, the conveying device includes a rotating shaft rotatably connected inside the housing, a push plate fixedly connected to the arc surface of the rotating shaft, a partition installed inside the feed frame with an opening between the partition and the feed frame, a baffle sliding through the feed frame and located directly below the partition, a pre-drilled hole on the surface of the baffle, and two first springs installed on one side of the baffle with the other end fixedly connected to the inner wall of the feed frame.
[0008] The effect achieved by the above components is as follows: When the shaft rotates, the shaft drives the push plate to rotate. When the push plate moves to the position of the baffle, the push plate pushes the baffle to move into the feed frame for easy movement. The first spring deforms, and finally the reserved hole of the push plate moves to the bottom of the baffle opening. At this time, calcium hydroxide falls into the interior of the shell through the opening on one side of the baffle and the reserved hole of the baffle. As the shaft continues to rotate, the push plate eventually moves past the baffle. Under the action of the return force of the first spring, the baffle moves back, and the reserved hole on the baffle is misaligned with the opening. The baffle blocks the opening, achieving the effect of blocking the calcium hydroxide. The conveying device achieves the effect of dispersing and conveying the calcium hydroxide, avoiding the situation where calcium hydroxide enters the interior of the shell at one time, thus preventing the calcium hydroxide from being crushed and the air separation from being incomplete.
[0009] Preferably, the motor is equipped with a first sprocket via a reducer, and a second sprocket is fixedly connected to the arc surface of the rotating shaft. The chain is looped between the first sprocket and the second sprocket, wherein the first sprocket can drive the second sprocket to rotate via the chain.
[0010] The effect achieved by the above components is as follows: when the motor is turned on, the motor drives the first sprocket to rotate, and the first sprocket drives the second sprocket and the shaft to rotate through the chain, thereby providing power for the rotation of the shaft.
[0011] Preferably, the upper surface of the partition is provided with a slope, wherein the slope is inclined in the direction of the opening.
[0012] The effect achieved by the above components is that the slope guides the calcium hydroxide, making it easier for the calcium hydroxide to enter the opening on one side of the partition.
[0013] Preferably, the baffle is rotatably connected to the push plate.
[0014] The effect achieved by the above components is that by setting the rotation between the rotating rod and the push plate, the friction between the push plate and the baffle is reduced, making it easier for the push plate to drive the baffle to move.
[0015] Preferably, the grinding roller is provided with a striking device inside, the striking device including a plurality of grooves, the plurality of grooves being circumferentially distributed inside the grinding roller, the grinding roller being fixedly connected to a second spring by means of the grooves, and a counterweight being fixedly connected to one end of the second spring.
[0016] The effect achieved by the above components is as follows: when the grinding roller rotates, the counterweight inside the grinding roller rotates with the grinding roller. When the counterweight moves to the top of the grinding roller, it moves downward under its own weight, and the second spring deforms. When the counterweight moves to the bottom, it strikes the inner wall of the grinding roller under the action of its own weight and the return force of the second spring, thus cleaning the calcium hydroxide on the grinding roller. By continuously striking the grinding roller through the striking device, the grinding roller is cleaned, preventing calcium hydroxide from clogging the gaps in the protrusions of the grinding roller and affecting its normal use.
[0017] Preferably, a rubber pad is fixedly connected to the side of the counterweight away from the second spring, wherein the size of the rubber pad is adapted to the size of the counterweight.
[0018] The effect achieved by the above components is that the rubber pads protect the counterweight and prevent damage from impacts between the counterweight and the grinding roller.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] When the shaft rotates, it carries the push plate. When the push plate moves to the position of the baffle, it pushes the baffle to move further into the feed frame. The first spring deforms, and the pre-drilled hole of the push plate eventually moves directly below the opening of the partition. At this point, calcium hydroxide falls into the interior of the shell through the opening on one side of the partition and the pre-drilled hole of the baffle. As the shaft continues to rotate, the push plate eventually moves past the partition. Under the action of the return force of the first spring, the baffle moves back, and the pre-drilled hole on the baffle is misaligned with the opening. The baffle blocks the opening, achieving the effect of blocking the calcium hydroxide. The conveying device achieves the effect of dispersing and conveying the calcium hydroxide, preventing the calcium hydroxide from entering the interior of the shell all at once, thus avoiding the situation of calcium hydroxide being crushed and incomplete air separation.

[0026] Reference Figure 1-4 As shown, this embodiment discloses a calcium hydroxide air separation device, including a shell 1, which is placed on the ground to provide support for the whole; a feed frame 4, which is installed on the top of the shell 1, wherein a conveying device 2 is provided inside the feed frame 4, wherein the conveying device 2 can disperse calcium hydroxide into the interior of the shell 1; a grinding roller 6, which is located inside the shell 1, wherein a plurality of protrusions are uniformly fixedly connected to the arc surface of the grinding roller 6; a motor 5, which is installed on one side of the shell 1, wherein the motor 5 can drive the grinding roller 6 to rotate by means of a reducer; a discharge channel 7, which is located inside the shell 1, wherein the discharge channel 7 is located directly below the grinding roller 6; a discharge pipe 8, which is installed at the bottom of the shell 1, wherein the discharge pipe 8 is connected to the discharge channel 7; and a high-pressure air pump 9, which is installed inside the shell 1, wherein the input end of the high-pressure air pump 9 is connected to the discharge channel 7 by means of a pipe, and the output end of the high-pressure air pump 9 is fixedly connected to a discharge pipe 10, wherein the other end of the discharge pipe 10 is located outside the shell 1. When calcium hydroxide needs to be air-separated, the worker feeds the calcium hydroxide into the inside of the feed frame 4. The conveying device 2 disperses the calcium hydroxide into the inside of the outer shell 1. The motor 5 is turned on, and the motor 5 drives the grinding roller 6 to rotate. The grinding roller 6 grinds and crushes the calcium hydroxide. The ground calcium hydroxide enters the inside of the feeding channel 7. At this time, the high-pressure air pump 9 is started. The high-pressure air pump 9 generates negative pressure, so that the calcium hydroxide powder is absorbed into the discharge pipe 10 and discharged to the outside of the outer shell 1 when it falls. The impurities in the calcium hydroxide are discharged through the discharge pipe 8.
[0027] Reference Figure 1-4As shown, the conveying device 2 includes a rotating shaft 21, which is rotatably connected to the inside of the outer casing 1, and a push plate 22 is fixedly connected to the arc surface of the rotating shaft 21; a partition 23, which is installed inside the feed frame 4, wherein an opening is formed between the partition 23 and the feed frame 4; a baffle 24, which slides through the feed frame 4, and is located directly below the partition 23, wherein a reserved hole 25 is provided on the surface of the baffle 24; and two first springs 26, which are installed on one side of the baffle 24, wherein the other end of the first spring 26 is fixedly connected to the inner wall of the feed frame 4. When the rotating shaft 21 rotates, it drives the push plate 22 to rotate as well. When the push plate 22 moves to the position of the baffle 24, it pushes the baffle 24 to move into the feed frame 4 for easy access. The first spring 26 deforms, and the reserved hole 25 of the push plate 22 eventually moves directly below the opening of the partition 23. At this time, calcium hydroxide falls into the interior of the outer shell 1 through the opening on one side of the partition 23 and the reserved hole 25 of the baffle 24. As the rotating shaft 21 continues to rotate, the push plate 22 eventually moves past the partition 23. Under the action of the return force of the first spring 26, the baffle 24 moves back, and the reserved hole 25 on the baffle 24 is misaligned with the opening. The baffle 24 blocks the opening, achieving the effect of blocking the calcium hydroxide. The conveying device 2 achieves the effect of dispersing and conveying the calcium hydroxide, preventing the calcium hydroxide from entering the interior of the outer shell 1 at once, thus avoiding the situation of calcium hydroxide being crushed and incomplete air separation.
[0028] Reference Figure 1-4 As shown, the motor 5 is equipped with a first sprocket 29 via a reducer, and a second sprocket 210 is fixedly connected to the arc surface of the shaft 21. A chain 211 is fitted onto the first sprocket 29 and the second sprocket 210, allowing the first sprocket 29 to drive the second sprocket 210 to rotate via the chain 211. When the motor 5 is turned on, the motor 5 rotates the first sprocket 29, which in turn drives the second sprocket 210 and the shaft 21 to rotate via the chain 211, thus providing power for the rotation of the shaft 21. A ramp 28 is provided on the upper surface of the partition 23, sloping towards the opening. The ramp 28 guides the calcium hydroxide, facilitating its entry into the opening on one side of the partition 23. A rotating rod 27 is rotatably connected to the baffle 24 corresponding to the push plate 22. The rotation between the rotating rod 27 and the push plate 22 reduces the friction between the push plate 22 and the baffle 24, facilitating the movement of the baffle 24 by the push plate 22.
[0029] Reference Figure 1-4As shown, the grinding roller 6 is equipped with a striking device 3 inside. The striking device 3 includes several grooves 31, which are circumferentially distributed inside the grinding roller 6. A second spring 32 is fixedly connected to the grinding roller 6 via the grooves 31, and a counterweight 33 is fixedly connected to one end of the second spring 32. When the grinding roller 6 rotates, the counterweight 33 inside the grinding roller 6 rotates with the grinding roller 6. When the counterweight 33 moves to the top of the grinding roller 6, it moves downward under its own weight, and the second spring 32 deforms. When the counterweight 33 moves to the bottom, it strikes the inner wall of the grinding roller 6 under the action of its own weight and the restoring force of the second spring 32, thus cleaning the calcium hydroxide on the grinding roller 6. By continuously striking the grinding roller 6 with the striking device 3, the grinding roller 6 is cleaned, preventing calcium hydroxide from clogging the gaps between the protrusions of the grinding roller 6 and affecting its normal use.
[0030] Reference Figure 1-4 As shown, a rubber pad 34 is fixedly connected to the side of the counterweight 33 away from the second spring 32, and the size of the rubber pad 34 is adapted to the size of the counterweight 33. By setting the rubber pad 34, the counterweight 33 is protected, preventing damage from impacts between the counterweight 33 and the grinding roller 6.
[0031] Working principle: When calcium hydroxide needs to be air-separated, the operator feeds calcium hydroxide into the feed frame 4 and turns on the motor 5. The motor 5 drives the grinding roller 6 and the first sprocket 29 to rotate. The first sprocket 29 drives the second sprocket 210 and the rotating shaft 21 to rotate via the chain 211. The rotating shaft 21 drives the push plate 22 to rotate. When the push plate 22 moves to the position of the baffle 24, the push plate 22 pushes the baffle 24 into the feed frame 4 for easy movement with the help of the rotating rod 27. The first spring 26 deforms, and finally the reserved hole 25 of the push plate 22 moves to the position directly below the opening of the partition 23. At this time, the calcium hydroxide falls into the interior of the outer shell 1 through the opening on one side of the partition 23 and the reserved hole 25 of the baffle 24. As the rotating shaft 21 continues to rotate, the push plate 22 finally moves past the partition 23. Under the action of the return force of the first spring 26, the baffle 24 moves back. The baffle 24 moves, and the reserved hole 25 on the baffle 24 is offset from the opening. The baffle 24 blocks the opening, which achieves the effect of blocking the calcium hydroxide. As the rotating shaft 21 rotates continuously, the push plate 22 will intermittently push the baffle 24 to move, so that the calcium hydroxide in the feed frame 4 will be continuously dispersed into the interior of the outer shell 1. The grinding roller 6 grinds and crushes the calcium hydroxide. The ground calcium hydroxide enters the interior of the feeding channel 7. At this time, the high-pressure air pump 9 is started. The high-pressure air pump 9 generates negative pressure, so that the calcium hydroxide powder is absorbed into the discharge pipe 10 and discharged to the outside of the outer shell 1 when it falls. The impurities in the calcium hydroxide are discharged through the discharge pipe 8. The conveying device 2 achieves the effect of dispersing and conveying the calcium hydroxide, avoiding the situation where the calcium hydroxide enters the interior of the outer shell 1 at one time, thus preventing the calcium hydroxide from being crushed and the air separation from being incomplete.
[0032] When the grinding roller 6 rotates, the counterweight 33 inside the grinding roller 6 rotates together with the grinding roller 6. When the counterweight 33 moves to the top of the grinding roller 6, it moves downward under its own weight, and the second spring 32 deforms. When the counterweight 33 moves to the bottom, under the action of its own weight and the restoring force of the second spring 32, the counterweight 33 taps the inner wall of the grinding roller 6 with the help of the rubber pad 34, thus achieving the effect of cleaning the calcium hydroxide on the grinding roller 6. By continuously tapping the grinding roller 6 with the tapping device 3, the effect of cleaning the grinding roller 6 is achieved, preventing calcium hydroxide from clogging the gaps of the protrusions of the grinding roller 6, thereby affecting the normal use of the grinding roller 6.
