[0022] like Figures 1 to 5 As shown, a machine-made sand dust removal device comprises a bracket 1, on which a separation mechanism 3 and a storage box 4 are installed, the separation mechanism 3 is connected to the storage box 4, the separation mechanism 3 comprises a separation box, the separation box comprises a side plate 31, a top plate 32 is arranged on the top of the side plate 31, an inclined plate 33 is arranged between the top plate 32 and the side plate 31, a conical tube 301 is connected to the bottom of the side plate 31, a discharge pipe 302 is arranged at the bottom of the conical tube 301, a feed hopper 34 is arranged on the top plate 32, and the inclined plate 33 is arranged between the top plate 32 and the side plate 31. An exhaust pipe 35 is provided on the inclined plate 33, and the exhaust pipe 35 is connected to a dust collection plate 351 after passing through the inclined plate 33. A first vertical slide groove 304 and a second vertical slide groove 305 are respectively provided on both sides of the side plate 31. A lifting plate 36 is slidably matched in the first vertical slide groove 304 and the second vertical slide groove 305. A wire screen 37 is provided in the middle of the lifting plate 36. The lifting plate 36 is arranged parallel to the dust collection plate 351, and a blower mechanism is provided under the lifting plate 36, and the blower mechanism drives the lifting plate 36 to move vertically.

[0023] The steps for using the machine-made sand dust removal device are as follows: Place the machine-made sand in the feed hopper 34, start the blower mechanism, so that the blower mechanism drives the lifting plate 36 to move vertically, the wire screen 37 on the lifting plate 36 is blown up, and the dust in the machine-made sand is blown up, and this part of the dust is sucked away by the dust collecting plate 351, and the dust that cannot be blown up falls into the storage box 4 from the second vertical chute 305. At this time, the blower mechanism and the dust collecting plate 351 are parallel to the lifting plate 36. While the blower mechanism blows air, the dust collecting plate 351 also collects dust at the same time, so that the amplitude of the lifting plate 36 reaches the maximum. When the amplitude reaches the maximum, the lifting plate 36 will move in the opposite direction, so that the lifting plate 36 vibrates back and forth, and then the dust is screened out multiple times. In addition, the blower mechanism and the dust collecting plate 351 of this case can also move intermittently to achieve a better screening effect. When the amplitude reaches the maximum, the blower mechanism and the dust collecting plate 351 stop working at the same time, then the lifting plate 36 is not affected by external force, but the machine-made sand will accelerate and move a certain distance due to inertia to separate the machine-made sand from the dust. The lifting plate 36 accelerates down under the action of the gravity of the machine-made sand. When the lifting plate 36 falls back, the blower mechanism and the dust collecting plate 351 work again, so that the vibration effect of the lifting plate 36 is better.

[0024] Repeat the above steps until there are no more impurities in the machine-made sand.

[0025] Through the above steps, the machine-made sand dust removal device can effectively separate impurities in the machine-made sand, making the separated machine-made sand purer, thereby improving product quality.

[0026] It is worth noting that when the hair dryer is not in operation for a period of time, dust may fall into the conical tube 301, and the dust falling there should be cleaned regularly.

[0027] In at least one embodiment, the hair blowing mechanism includes a sliding block 51, and in cooperation with the sliding block 51, a sliding groove is provided on the inner wall of the side panel 31, and the sliding block 51 is slidably fitted in the sliding groove, and a locking bolt is provided on the sliding block 51, and the locking bolt can enable the sliding block 51 to move along the sliding groove and position at a point on the sliding groove, and a connecting rod 52 is provided between the two sliding blocks 51, and a plurality of rotating shafts 53 are provided on the connecting rod 52, and a high-pressure jet head 54 is installed on the rotating shaft 53, and the high-pressure jet head 54 is connected to an air pump.

[0028] In at least one embodiment, Figure 1 and Figure 2 As shown, a guide hole 311 is provided at the bottom of the first vertical slide groove 304 and the second vertical slide groove 305, and a guide rod 312 is slidably fitted in the guide hole 311. A flexible spring 313 is provided between the bottom of the guide hole 311 and the guide rod 312, and the upper end of the guide rod 312 is fixedly connected to the lifting plate 36.

[0029] Furthermore, a dustproof plate 38 is connected to the left end of the lifting plate 36, and a dustproof cover 39 is provided on the outer wall of the side plate 31. The dustproof plate 38 can be used to block the first vertical slide groove 304, and the dustproof cover 39 further prevents dust from escaping from there to the outside.

[0030] Working mode: During the use of the embodiment of the blower mechanism, the flexible spring 313 plays a certain accelerating role. When the lifting plate 36 moves to the highest point of vertical displacement, the flexible spring 313 is in a stretched state, providing a downward pulling force. When the blower mechanism and the dust collecting plate 351 are not working, the lifting plate 36 is accelerated to move downward. When the lifting plate 36 moves to the lowest point of vertical displacement, the flexible spring 313 is in a compressed state, increasing a vertical upward thrust. The blower mechanism and the dust collecting plate 351 start to work, causing the lifting plate 36 to move upward.

[0031] In at least one embodiment, Figure 3 and Figure 4 As shown, a guide hole 311 is provided at the bottom of each of the first vertical slide groove 304 and the second vertical slide groove 305, a guide rod 312 is slidably fitted in the guide hole 311, a first permanent magnet 315 is provided at the bottom of the guide rod 312, and a second permanent magnet 314 is provided at the bottom of the guide hole 311, and the first permanent magnet 315 and the second permanent magnet 314 repel each other magnetically.

[0032] Working mode, during the use of the hair dryer mechanism embodiment, the cooperation of the two permanent magnets can make the vertical movement of the lifting plate 36 more inclined to free fall motion. When the lifting plate 36 moves to the highest point of vertical displacement, the first permanent magnet 315 and the second permanent magnet 314 are too far apart, and the two do not play any role. The lifting plate 36 accelerates down under the action of the gravity of the machine-made sand. When the lifting plate 36 moves to make the guide rod 312 close to the bottom of the guide hole 311, the first permanent magnet 315 and the second permanent magnet 314 magnetically repel each other, preventing the guide rod 312 from touching the bottom of the guide hole 311, thereby avoiding equipment damage. This process is similar to the process of emergency braking, which ensures the safety of the equipment.

[0033] Furthermore, the end of the lifting plate 36 passes through the second vertical slide groove 305 and extends into the storage box 4.

[0034] In at least one embodiment, the storage box 4 includes a lower plate 41, a left plate 43 and an upper plate 42, wherein the upper plate 42 is fixedly connected to the lower plate 41 by two supporting connecting plates, the left plate 43 is fixedly connected to the left side of the lower plate 41, and a channel for accommodating the up and down movement of the lifting plate 36 is formed between the left plate 43 and the upper plate 42, and the channel can also accommodate machine-made sand falling into the storage box 4, and the right side of the lower plate 41 is rotatably connected to a blocking door 44.

[0035] Furthermore, a positioning block 46 is provided on the top of the blocking door 44 , and in coordination therewith, a positioning slot 47 is provided on the upper plate 42 to cooperate with the positioning block 46 .

[0036] Furthermore, a transparent glass 45 is provided on the blocking door 44 , through which people can observe the feeding of the machine-made sand in the storage box 4 .

[0037] Furthermore, the dust suction plate 351 is provided with a plurality of dust suction holes to suck away the dust therefrom.

[0038] Furthermore, a sealing plate 303 is rotatably connected to the pipe mouth of the discharge pipe 302, and the sealing plate 303 can seal the discharge pipe to prevent the discharge pipe 302 from leaking material from there, and can also make the discharge pipe 302 connected to the outside world to facilitate the leakage of the separated machine-made sand from there.

[0039] In at least one embodiment, the bracket 1 includes a mounting plate 11 , and a plurality of legs 12 are provided at the bottom of the mounting plate 11 .

[0040] The solution is refined. The mounting plate 11 is provided with a positioning mounting hole for accommodating the insertion of the separation mechanism.

[0041] In at least one embodiment, a vertical rod 361 is provided on one side of the lifting plate 36 close to the storage box 4, and a rack 362 is provided on the vertical rod 361, and in coordination with the vertical rod 361, a first gear 363 is rotatably connected to the side plate 31, and the rack 362 is meshed with the first gear 363, and a first rotating shaft 364 is rotatably connected to the side plate 31, and a second gear is installed on the first rotating shaft 364, and the first gear 363 is meshed with the second gear, and a sand removing tooth 365 is also fixedly connected to the first rotating shaft 364.

[0042] Working mode, the mechanism can perform secondary turning of machine-made sand. When the lifting plate 36 moves vertically under the action of the blower mechanism and the dust collecting plate 351, when the lifting plate 36 moves vertically upward, the vertical rod 361 drives the rack 362 to move vertically, and the rack 362 drives the first gear 363 to rotate counterclockwise, so that the second gear rotates clockwise, and therefore the sand-moving tooth 365 also rotates clockwise. Figure 5As shown, the machine-made sand gradually slides from the lifting plate 36 from the left side to the right side, and a part of the machine-made sand will come into contact with the sand-swiping teeth 365, and this part of the machine-made sand will be flipped by the sand-swiping teeth 365 to the bottom of the dust collecting plate 351, which is beneficial to the separation of dust and machine-made sand. When the lifting plate 36 moves vertically downward, the blower mechanism and the dust collecting plate 351 are not working. At this time, if machine-made sand falls into the sand-swiping teeth 365, the sand-swiping teeth 365 will rotate counterclockwise under the force, then the second gear will rotate counterclockwise, and the first gear 363 will rotate clockwise, then the rack 362 will move vertically downward to accelerate the downward movement of the lifting plate 36, thereby changing the vertical lifting amplitude of the lifting plate 36, so that the vibration separation effect is better.
