DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] At present, when the fire-fighting powder is dried by heating air, the commonly used feeding assembly fills the internal space of the barrel, which is not conducive to the rapid flow of air inside the barrel, reduces the efficiency of the fire-fighting powder drying, and is not conducive to improving the drying rate of the fire-fighting powder.

[0041] See also Figures 1 to 3 and Figure 5It can be seen that the first embodiment of the present invention provides a dryer for producing fire-fighting powder, including a support frame 1, on which a drying cylinder 2 is fixedly arranged, and also includes a feeding assembly 3, the feeding assembly 3 includes a rotating shaft 301 rotatably arranged in the drying cylinder 2, and the rotating shaft 301 is fixedly provided with a plurality of fixing members 302 distributed along the extension direction of the rotating shaft 301, and each fixing member 302 is fixedly provided with a feeding member 303, and a chamber 305 is opened in the fixing member 302, and a sliding member 304 is slidably arranged in each chamber 305, and one end of the sliding member 304 extends out of the chamber 305 and is fixedly provided with a collecting member 307, and the collecting member 307 slides with the corresponding feeding member 303 Dynamic connection is used to push the material to move; the feeding assembly 3 also includes a motor 306 fixedly arranged on one side of the support frame 1, one end of the rotating shaft 301 extends out of the drying cylinder 2 and is coaxially fixedly connected with the output end of the motor 306; an air inlet 201, a blower 203 and an air heater 202 are arranged on one side of the drying cylinder 2, and a discharge port 204 is arranged on the other side of the drying cylinder 2, the upper side of the drying cylinder 2 is connected to a feeding mechanism 6, and the upper side of the drying cylinder 2 close to the discharge port 204 is connected to a bag dust collector 7, a plurality of claws are fixedly arranged on the drying cylinder 2, each of which is threadedly connected to a screw, and a sealing member is arranged on the drying cylinder 2, and each screw can contact the sealing member.

[0042] During specific use, the screw is rotated to make the seal in close contact with the drying cylinder 2 to ensure the sealing performance, and the blower 203 and the air heater 202 are started. The heated air is transported to the interior of the drying cylinder 2 through the air inlet 201. After heating for a certain period of time, when the drying temperature requirement is reached, the undried firefighting powder is transported to the interior of the drying cylinder 2 through the feeding mechanism 6. At the same time, the motor 306 and the bag filter 7 are started. The motor 306 drives the rotating shaft 301 to rotate, and the rotating shaft 301 drives the fixing part 302 to rotate. The fixing part 302 is spirally distributed along the axial direction of the rotating shaft 301, and the fixing part 302 drives the corresponding feeding part 303 and collecting part 303. 07 rotates, so that the feeding piece 303 pushes the fire-fighting powder to move in the direction of the discharge port 204. At the same time, since the collecting piece 307 is an arc-shaped L-shape, the collecting piece 307 can drive more materials to move, and the feeding piece 303 is spirally arranged, which can quickly realize the movement of materials and prevent the accumulation of materials. At the same time, there is a large gap between the feeding piece 303 and the rotating shaft 301, which can prevent the heated air from being blocked and unable to move quickly in the direction of the discharge port 204, thereby improving the rapid increase and uniform distribution of temperature. At the same time, the spiral feeding piece 303 can accelerate the movement of the heated air, which is conducive to the hot air quickly spreading throughout the entire drying cylinder 2.

[0043] By leaving a large gap between the feeding piece 303 and the rotating shaft 301, the air can be prevented from being blocked and unable to circulate quickly. At the same time, the spiral setting of the feeding piece 303 can realize the rapid movement of materials and push the hot air to move quickly away from the air heater 202, which is conducive to the rapid circulation of air and uniform distribution of temperature.

[0044] Embodiment 2

[0045] During specific use, although the above-mentioned feeding piece can realize faster flow of hot air and rapid transportation of materials, the rapid movement of materials reduces the contact time between materials and hot air, which can easily lead to insufficient contact between materials and hot air, resulting in some materials unable to obtain a good drying effect, which is not conducive to ensuring product quality.

[0046] In order to solve the above technical problems, based on the above embodiment 1, Figures 1 to 9 It can be obtained that the adopted technical solution includes a dispersing component 4, and a plurality of dispersing components 4 are provided. The dispersing components 4 are arranged on the drying cylinder 2 and are used to disperse the materials. Each dispersing component 4 includes an elastic member 401 fixedly arranged inside the drying cylinder 2, and each dispersing component 4 includes a plurality of air storage tanks 403 opened inside the drying cylinder 2. The elastic member 401 is connected with the corresponding air storage tank 403 through a connecting pipe 402. A first piston rod 405 is slidably arranged in each air storage tank 403, and the first piston rod 405 extends into the interior of the drying cylinder 2 and is slidably connected with the drying cylinder 2. The elastic member 401 includes a cylinder 406 fixedly arranged in the drying cylinder 2, and a second piston rod 407 is slidably arranged in each cylinder 406, and the second piston rod 407 is away from the connecting pipe 40 High-pressure gas is filled between one side of 2 and the corresponding cylinder 406, the second piston rod 407 extends into the drying cylinder 2 at one end away from the connecting pipe 402 and is fixedly provided with a striking piece 408, a plurality of accommodating grooves 409 corresponding to the striking piece 408 are provided in the drying cylinder 2, and the striking piece 408 can be inserted into the corresponding accommodating grooves 409; the vibration component 5 includes a rotating shaft 501 rotatably arranged in the drying cylinder 2, a swinging piece 502 is fixedly arranged on the rotating shaft 501, and a sliding groove 503 is provided on the swinging piece 502, an insertion rod 504 inserted into the sliding groove 503 is fixedly provided on the first piston rod 405, a plurality of yielding grooves 505 corresponding to the swinging piece 502 are provided in the drying cylinder 2, and the swinging piece 502 can be inserted into the corresponding yielding grooves 505.

[0047] When in use, based on the above embodiment, a breaking up component 4 is arranged between every two adjacent collecting pieces 307. When the fixing piece 302 rotates, the fixing piece 302 drives the collecting piece 307 to rotate through the sliding piece 304. The collecting piece 307 located on the front side first contacts with the corresponding striking piece 408. After rotating a certain angle, the adjacent collecting pieces 307 and the feeding piece 303 contact with the corresponding swinging piece 502 and push the swinging piece 502 to swing into the give way groove 505 on the corresponding side. At the same time, the swinging piece 502 drives the corresponding first piston rod 405 to move into the air storage tank 403 through the insertion rod 504, so that the gas in the air storage tank 403 is discharged into the corresponding cylinder 406 through the connecting pipe 402.

[0048] Then the gas pushes the second piston rod 407 to move upward, and the high-pressure gas between the second piston rod 407 and the corresponding cylinder 406 is compressed. At the same time, the second piston rod 407 pushes the corresponding striking member 408 to move out of the corresponding receiving groove 409, pushing the collecting member 307 to slide toward the axis of the rotating shaft 301, and the sliding member 304 is pressed into the corresponding chamber 305. The gas in the chamber 305 is compressed, so that the collecting member 307 drives the powder thereon to be sprinkled toward the position where the hot air flows in the drying cylinder 2, which can make the powder fully contact with the heated air, increase the contact area between the hot air and the powder, and thus increase the effect of the hot air in removing moisture inside the powder.

[0049] At the same time, the collecting member 307 can scrape the feeding member 303 to prevent the wet powder from adhering to the feeding member 303, which would lead to a decrease in drying efficiency, and the feeding member 303 from adhering to too much powder, which would lead to a decrease in conveying efficiency.

[0050] When the adjacent feeding member 303 and collecting member 307 are no longer in contact with the corresponding swinging member 502, under the action of the high-pressure gas, the second piston rod 407 moves toward the connecting pipe 402, so that the striking member 408 is inserted into the corresponding receiving groove 409, and the sliding member 304 is reset under the action of the gas in the chamber 305. At the same time, the second piston rod 407 pushes the gas on the lower side to be discharged into the corresponding gas storage tank 403 through the connecting pipe 402, so that the first piston rod 405 drives the insertion rod 504 and the swinging member 502 to swing outward under the action of the air pressure, so that the swinging member 502 swings out of the corresponding clearance groove 505 again.

[0051] By providing a swinging swinging member 502 and a striking member 408 capable of striking the collecting member 307, the powder on the feeding member 303 and the corresponding collecting member 307 can be broken up, while increasing the contact area with the hot air, thereby improving the drying efficiency of the powder and meeting the demand for rapid discharge. At the same time, the collecting member 307 can scrape the powder attached to the feeding member 303 to prevent excessive undried powder from being attached to the feeding member 303, resulting in the phenomenon that lumps of undried powder are removed from the discharge port 204.

[0052] Embodiment 3

[0053] On the basis of the above-mentioned embodiment 1 and embodiment 2, the material can be quickly transported and the contact area between the powder and the hot air can be increased, thereby improving the drying quality and efficiency. However, the collecting piece and the feeding piece cannot vibrate, resulting in the undried powder easily adhering to the side where the collecting piece and the feeding piece are not in contact, resulting in the accumulation of blocks and then being discharged from the discharge port, resulting in a decrease in product quality.

[0054] On the basis of the above-mentioned embodiment 1 and embodiment 2, in order to solve the above-mentioned technical problem, Figures 1 to 10 It can be seen that the adopted technical solution includes a vibration component 5, and a plurality of vibration components 5 are provided. The vibration component 5 is arranged on the corresponding breaking up component 4 to make the breaking up component 4 vibrate. The vibration component 5 includes a rotating shaft 501 rotatably arranged in the drying cylinder 2, and a swinging member 502 is fixedly arranged on the rotating shaft 501. A sliding groove 503 is provided on the swinging member 502. An insertion rod 504 inserted into the sliding groove 503 is fixedly provided on the first piston rod 405, and a plurality of protrusions 506 capable of contacting the insertion rod 504 are fixedly provided on one side wall of the sliding groove 503. A plurality of make way grooves 505 corresponding to the swinging member 502 are provided in the drying cylinder 2, and the swinging member 502 can be inserted into the corresponding make way grooves 505.

[0055] During specific use, based on the above-mentioned embodiment one and embodiment two, the number of vibration components 5 and the breaking up components 4 are set to be the same. While the swinging member 502 is swinging, the swinging member 502 drives the insertion rod 504 to move through the side wall of the sliding groove 503, and the insertion rod 504 drives the first piston rod 405 to move in the gas storage tank 403 toward the connecting pipe 402. At this time, since a plurality of protrusions 506 are fixedly provided on the side wall of the sliding groove 503, the insertion rod 504 vibrates under the action of the protrusions 506, so that the insertion rod 504 drives the gas in the gas storage tank 403 to vibrate through the first piston rod 405.

[0056] Therefore, through the transmission vibration of the gas, when the gas is discharged into the cylinder 406 through the connecting pipe 402, the second piston rod 407 vibrates, and the second piston rod 407 drives the collecting part 307 to vibrate through the striking part 408, and the collecting part 307 drives the sliding part 304 and the feeding part 303 to vibrate, so as to play the role of shaking off the powder attached to the collecting part 307 and the feeding part 303, and prevent the powder attached to both sides of the collecting part 307 and the feeding part 303 to affect the quality of the product, so that all the powder can contact with the hot air, and at the same time achieve the effect of intermittently scattering the powder gradually, which is more conducive to the full contact of the powder with the heated air to achieve the purpose of drying; at the same time, the exhaust gas is discharged through the bag dust collector 7, and the discharged exhaust gas is treated and then discharged.

[0057] By setting the protrusion 506, when the insertion rod 504 moves in the sliding groove 503, the insertion rod 504 can drive the collecting piece 307 and the feeding piece 303 to vibrate through a series of components, thereby shaking off the powder attached to the collecting piece 307 and the feeding piece 303, preventing the powder from agglomerating, resulting in the inability to contact with hot air, poor drying effect, and reduced product quality; through the arrangement of the above-mentioned components, the powder can be fully contacted with the hot air, and at the same time, the effect of intermittently scattering the powder gradually is achieved, which is more conducive to the full contact between the powder and the hot air, while improving the efficiency, improving the drying quality of the powder, and achieving a better drying effect.

[0059] On the basis of the above embodiment, this embodiment also provides a method for using a dryer for producing fire-fighting powder, comprising the following specific steps:

[0060] S1. Rotate the screw to make the seal in close contact with the drying cylinder 2 to ensure the tightness of the drying cylinder 2, start the blower 203 and the air heater 202, deliver hot air to the drying cylinder 2 through the air inlet 201, and then feed the material into the drying cylinder 2 through the feeding mechanism 6;

[0061] S2. The material is moved toward the discharge port 204 by the feeding component 3, so that the feeding member 303 drives the powder to move toward the discharge port 204, and the material is broken up by the breaking component 4, and the collecting member 307 and the feeding member 303 are vibrated by the vibration component 5 to prevent the powder from adhering;

[0062] S3. The exhaust gas discharged from the drying cylinder 2 is collected and processed by the bag filter 7;
