Description

Technical Field

[0001] The present invention belongs to the technical field of the structural design of a feeding spoon, and particularly relates to an adjustable pressure relief and buffer feeding spoon. Background Art

[0002] For the transfer point of bulk materials, due to the height difference at the transfer point, during the falling process of the materials in the chute, the potential energy is continuously converted into kinetic energy. As the speed continuously increases, a strong induced wind is generated during discharging. The feeding spoon is a feeding device for eliminating the potential energy of the materials and the induced wind. The feeding device is an auxiliary device in the mechanized storage and transportation system of a lime production enterprise. Its main function is to continuously and evenly feed the processed or unprocessed materials from a certain device to the receiving device or transportation machinery.

[0003] However, the feeding structure at the bottom end of the traditional feeding spoon reduces the dynamic potential energy of the materials through an inclined design.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 、 Figure 4 、 Figure 6 and Figure 8As shown in the figure, an adjustable pressure relief buffer feeding spoon is provided in an embodiment of the present invention, which specifically includes a feeding square pipe 1. Feeding structures 2 are fixedly connected to the upper and lower ends of the feeding square pipe 1. An adjusting structure 6 is connected to the feeding structure 2. Next, we will introduce the specific structures and functions of the feeding structure 2 and the adjusting structure 6 in detail as follows. The feeding structure 2 specifically includes a feeding pipe 201 with an arc-shaped cross-section and a feeding hopper 202 fixedly connected to the feeding pipe 201. The top end of the feeding square pipe 1 is fixedly connected to the feeding pipe 201, and the bottom end of the feeding square pipe 1 is fixedly connected to a blanking pipe 203. The bottom end of the blanking pipe 203 is rotatably connected to a connection head 204. The bottom end of the connection head 204 is fixedly connected to a corrugated pipe 205. The bottom end of the corrugated pipe 205 is fixedly connected to a blanking hopper 206 with an arc-shaped cross-section. An induced air flow port 207 is provided on the feeding pipe 201. The adjusting structure 6 specifically includes a fixing ring 601 and a connecting strip 602 fixedly connected to the fixing ring 601. A fixing ring 601 is fixedly connected to the connection head 204. A second screw rod 603 is threadedly connected to the connecting strip 602. A fixing seat 605 is fixedly connected to the blanking hopper 206. A mounting shaft 606 is fixedly connected to the fixing seat 605. A rotating seat 607 is rotatably connected to the mounting shaft 606. The bottom end of the second screw rod 603 is rotatably connected to the rotating seat 607. The top end of the second screw rod 603 is slidably connected to a second rotating rod 604. The cross-section of the second rotating rod 604 is in an "I" shape structure.

[0037] Specifically in this embodiment, the material enters from the feeding hopper 202. The arc-shaped feeding pipe 201 reduces the gravitational potential energy of the material, thereby reducing the impact of the material on the feeding square pipe 1 and reducing the wear of the feeding square pipe 1. After the material falls from the feeding square pipe 1, it enters the interior of the blanking pipe 203, then flows out from the connection head 204 at the bottom end of the blanking pipe 203, then flows to the corrugated pipe 205, and then is discharged from the arc-shaped blanking hopper 206, reducing the dynamic potential energy of the material again. At the same time, the induced wind is reduced, the impact of the material on the material receiving device is reduced, and the wear of the material receiving device is reduced.

[0038] When it is necessary to adjust the inclination angle of the blanking hopper 206, the second rotating rod 604 can be rotated. When the second rotating rod 604 rotates, the second rotating rod 604 rotates to drive the second screw rod 603 to rotate. When the second screw rod 603 rotates, it moves up and down on the connecting strip 602. When the second screw rod 603 moves up and down, it drives the rotating seat 607 to move up and down. The up and down movement of the rotating seat 607 drives the mounting shaft 606 and the fixing seat 605 to move up and down. The up and down movement of the fixing seat 605 drives the end of the blanking hopper 206 to move up and down, and at the same time deforms the corrugated pipe 205. In this way, the inclination angle of the blanking hopper 206 can be quickly adjusted, which is convenient for pressure relief of material receiving devices at different heights and reduces the wear of the material receiving devices.

[0039] Please refer to Figure 4 and Figure 8As shown in the figure, a steering structure 7 is connected to the feeding structure 2. The steering structure 7 specifically includes a mounting ring 701. A mounting ring 701 is fixedly connected to the blanking pipe 203. Four clamping holes 702 are arranged in a circumferential array on the mounting ring 701. A mounting sleeve 703 is fixedly connected to the connecting bar 602. A clamping rod 704 with a "soil"-shaped cross-section is slidably connected inside the mounting sleeve 703. The clamping rod 704 is engaged with one of the clamping holes 702. A second spring 705 is fixedly connected between the clamping rod 704 and the mounting sleeve 703. A limiting ring 706 is fixedly connected to the connecting head 204. A limiting groove 707 is arranged on the blanking pipe 203. The limiting ring 706 is rotatably connected to the limiting groove 707.

[0040] Specifically in this embodiment, when feeding the receiving equipment in different directions, the clamping rod 704 at the bottom end of the connecting bar 602 can be pulled. The clamping rod 704 slides and no longer engages with one of the clamping holes 702 on the mounting ring 701. At the same time, the sliding of the clamping rod 704 compresses the second spring 705. Then the connecting head 204 and the corrugated pipe 205 are rotated, and the direction of the hopper 206 is driven to rotate at the same time. When the discharge port of the hopper 206 rotates to the appropriate position, the clamping rod 704 can be released. The second spring 705 resets, driving the clamping rod 704 to reset. The clamping rod 704 then engages with the clamping holes 702 in other positions on the mounting ring 701, thereby fixing the blanking direction of the hopper 206, facilitating the feeding of the receiving equipment in different directions, improving the applicability of the equipment. The setting of the limiting ring 706 and the limiting groove 707 improves the stability of the rotation of the connecting head 204.

[0041] Please refer to Figure 1 、 Figure 4 and Figure 6 As shown in the figure, a buffer structure 5 is arranged inside the feeding square pipe 1. The buffer structure 5 specifically includes a motor 501 and a transmission shaft 502 fixedly connected to the output end of the motor 501. The motor 501 is fixedly connected to the feeding square pipe 1. A rotating cylinder 503 is fixedly connected to the transmission shaft 502. A plurality of partition plates 504 are arranged in a circumferential array on the rotating cylinder 503. A plurality of staggered and inclined blanking plates 505 are fixedly connected to the inner wall of the feeding square pipe 1.

[0042] Specifically in this embodiment, when the material enters the feeding square pipe 1 from the feeding pipe 201, the motor 501 is started. The motor 501 drives the transmission shaft 502 to rotate. The rotation of the transmission shaft 502 drives the rotating cylinder 503 to rotate. The rotation of the rotating cylinder 503 drives a plurality of partition plates 504 to rotate. The partition plates 504 evenly divide the material into equal parts, and the material is evenly fed. The material is fed from the inclined blanking plates 505. The inclined setting of the blanking plates 505 buffers the descending material and reduces the potential energy of the material.

[0043] Please refer to Figures 1 to 10As shown, an ash collecting structure 3 is connected to the feeding square tube 1 and the feeding structure 2. The ash collecting structure 3 specifically includes an air suction hood 301 and an air duct 302 fixedly connected to the air suction hood 301. The outer cover of the air ducting inlet 207 on the feeding pipe 201 is provided with an air suction hood 301. A collecting box 303 is fixedly connected to one side of the feeding square tube 1, and the end of the air duct 302 away from the air suction hood 301 is fixedly connected to the collecting box 303. A support plate 304 is fixedly connected to one side of the collecting box 303, a vacuum pump 305 is fixedly connected to the support plate 304, and an air suction duct 306 is fixedly connected between the vacuum pump 305 and the collecting box 303. A filter screen 310 is detachably connected to the collecting box 303, a collecting box 307 is slidably connected to the collecting box 303, a first sealing gasket 309 is fixedly connected to the collecting box 307, and the first sealing gasket 309 is in conflict with the collecting box 303. The collection box 303 is fixedly connected with two fixed blocks 311, the fixed blocks 311 are slidably connected with guide rods 312, the guide rods 312 are rotatably connected with clamping blocks 314, the collection box 307 is fixedly connected with two positioning posts 316, the clamping blocks 314 are provided with positioning holes 315, and the positioning posts 316 are plugged into the positioning holes 315. A first spring 313 is fixedly connected between the guide rods 312 and the fixed blocks 311, the cross section of the guide rods 312 is a T-shaped structure, and the collection box 307 is fixedly connected with a first handle 308, the cross section of the first handle 308 is a U-shaped structure.

[0044] Specifically in the present embodiment, when the material is fed, the vacuum pump 305 can be started, and the vacuum pump 305 makes the interior of the collection box 303 in a negative pressure state through the suction pipe 306, and the collection box 303 makes the interior of the suction hood 301 in a negative pressure state through the air duct 302. The suction hood 301 extracts the induced wind and light dust generated during the feeding through the air duct 207, and at the same time, the dust enters the interior of the collection box 303 through the air duct 302. When the pressure on the pressure gauge on the vacuum pump 305 is too high, it is necessary to clear the dust inside the collection box 307. At this time, the two blocks 314 can be pulled first, and the blocks 314 drive the guide rod 312 to slide, and the first spring 313 is compressed. When the positioning hole 315 on the block 314 is no longer aligned with the positioning hole 315 on the collection box 307 After the column 316 is engaged, the block 314 can be rotated so that the block 314 no longer blocks the collection box 307. At this time, the first handle 308 can be pulled to pull out the collection box 307, and then the dust inside the collection box 307 can be taken out, and then the dust on the filter screen 310 on the collection box 303 can be cleaned. After cleaning the dust, the collection box 307 with the dust poured out is sent into the interior of the collection box 303, and the block 314 is pulled first to compress the first spring 313, and then the block 314 is rotated to align the positioning hole 315 on the block 314 with the positioning column 316 on the collection box 307, and then the block 314 is released, and the block 314 contacts the collection box 307, and the sealing between the collection box 307 and the collection box 303 is improved by the first sealing gasket 309.

[0045] Please refer to Figure 2 and Figure 7 As shown, the screening structure 4 specifically includes a screen 401 and a second handle 402 fixedly connected to the screen 401. The screen 401 is slidably connected to the suction hood 301, and the cross-section of the second handle 402 is a U-shaped structure. A second gasket 403 is fixedly connected to the screen 401, and the second gasket 403 abuts against the suction hood 301. Two rotating shafts 404 are rotatably connected to the suction hood 301, a connecting block 405 is fixedly connected to the rotating shaft 404, a first screw rod 406 is threadedly connected to the connecting block 405, a resisting block 407 is fixedly connected to the first screw rod 406, and the resisting block 407 abuts against the screen 401. The end of the first screw rod 406 is slidably connected to a first rotating rod 408, and the cross-section of the first rotating rod 408 is an "I"-shaped structure.

[0046] Specifically in this embodiment, when it is necessary to replace the screen 401 according to different materials, the first rotating rod 408 can be rotated. The first rotating rod 408 drives the first screw rod 406 to rotate, and the rotation of the first screw rod 406 further drives the resisting block 407 to move. The resisting block 407 no longer abuts against the screen 401. At this time, the rotating shaft 404 can be rotated so that the resisting block 407 no longer blocks the screen 401. At this time, the screen 401 can be pulled out through the second handle 402. After replacing the screen 401 with different mesh numbers, the new screen 401 can be inserted, then the rotating shaft 404 is rotated again, and then the first rotating rod 408 is rotated so that the resisting block 407 abuts against the screen 401. Then the first rotating rod 408 is continuously rotated, so that the first screw rod 406 continues to advance, making the abutment of the resisting block 407 tighter, thereby cooperating with the second gasket 403 to improve the sealing performance of the suction hood 301.

[0047] When the present invention is in use, first, materials enter from the feed hopper 202, and the arc-shaped feed pipe 201 reduces the gravitational potential energy of the materials, thereby reducing the impact of the materials on the feeding square pipe 1 and lowering the wear of the feeding square pipe 1. After the materials fall from the feeding square pipe 1, they enter the interior of the blanking pipe 203 and flow out from the connector 204 at the bottom of the blanking pipe 203, then flow to the corrugated pipe 205 and are discharged from the arc-shaped blanking hopper 206, reducing the dynamic potential energy of the materials again. At the same time, the induced wind is reduced, the impact of the materials on the receiving equipment is reduced, and the wear of the receiving equipment is reduced. When it is necessary to adjust the inclination angle of the blanking hopper 206, the second rotating rod 604 can be rotated. When the second rotating rod 604 rotates, the second rotating rod 604 rotates to drive the second screw rod 603 to rotate. When the second screw rod 603 rotates, it moves up and down on the connecting strip 602. When the second screw rod 603 moves up and down, it drives the rotating seat 607 to move up and down. The up and down movement of the rotating seat 607 drives the mounting shaft 606 and the fixed seat 605 to move up and down. The up and down movement of the fixed seat 605 drives the end of the blanking hopper 206 to move up and down, and at the same time deforms the corrugated pipe 205, thereby quickly adjusting the inclination angle of the blanking hopper 206, facilitating pressure relief for receiving equipment at different heights, and reducing the wear of the receiving equipment.

[0048] Then, when it is necessary to feed receiving equipment in different directions, the clamping rod 704 at the bottom of the connecting strip 602 can be pulled. When the clamping rod 704 slides, it no longer engages with one of the clamping holes 702 on the mounting ring 701. At the same time, when the clamping rod 704 slides, the second spring 705 is compressed. Then, the connector 204 and the corrugated pipe 205 are rotated, driving the blanking hopper 206 to rotate in the direction. When the discharge port of the blanking hopper 206 rotates to the appropriate direction, the clamping rod 704 can be released, and the second spring 705 resets, driving the clamping rod 704 to reset. The clamping rod 704 then engages with the clamping holes 702 in other directions on the mounting ring 701, thereby fixing the blanking direction of the blanking hopper 206, facilitating feeding of receiving equipment in different directions, improving the applicability of the equipment. The setting of the limiting ring 706 and the limiting groove 707 improves the stability of the rotation of the connector 204.

[0049] Secondly, when the materials enter the feeding square pipe 1 from the feed pipe 201, the motor 501 is started. The motor 501 drives the transmission shaft 502 to rotate. The rotation of the transmission shaft 502 drives the rotating cylinder 503 to rotate. The rotation of the rotating cylinder 503 drives a plurality of partition plates 504 to rotate. The partition plates 504 evenly divide the materials into equal parts, and the materials are then evenly fed. The materials are fed from the inclined blanking plate 505. The inclined setting of the blanking plate 505 buffers the descending materials and reduces the potential energy of the materials.

[0050] Finally, when the material is fed, the vacuum pump 305 can be started. The vacuum pump 305 makes the interior of the collection box 303 in a negative pressure state through the suction pipe 306. The collection box 303 makes the interior of the suction hood 301 in a negative pressure state through the air duct 302. The suction hood 301 extracts the induced wind and light dust generated during the feeding through the air duct 207. At the same time, the dust enters the interior of the collection box 303 through the air duct 302. When the pressure gauge on the vacuum pump 305 is too high, it is necessary to clear the dust inside the collection box 307. At this time, the two blocks 314 can be pulled first. The block 314 drives the guide rod 312 to slide, and the first spring 313 is compressed. When the positioning hole 315 on the block 314 is no longer engaged with the positioning column 316 on the collection box 307, the block 314 can be rotated, and then the block 314 no longer blocks the collection box 307. At this time, the first handle 308 can be pulled to pull out the collection box 307, and then the dust inside the collection box 307 can be taken out, and then the dust on the filter screen 310 on the collection box 303 can be cleaned. After the dust is cleaned, the collection box 307 with the dust emptied is sent into the interior of the collection box 303, and the block 314 is pulled first. , the first spring 313 is compressed, and then the block 314 is rotated to align the positioning hole 315 on the block 314 with the positioning column 316 on the collection box 307, and then the block 314 is released, the block 314 contacts the collection box 307, and the sealing between the collection box 307 and the collection box 303 is improved by the first sealing gasket 309. When the screen 401 needs to be replaced according to different materials, the first rotating rod 408 can be rotated, and the first rotating rod 408 drives the first screw 406 to rotate, and the first screw 406 rotates to drive the block 407 to move, and the block 407 is no longer in contact with the screen 401 01 contacts, at this time, the rotating shaft 404 can be rotated so that the block 407 no longer blocks the screen 401, and the screen 401 can be pulled out through the second handle 402.
