Description

Technical Field

[0001] The present invention belongs to the technical field of yellow phosphorus raw material transportation, and particularly relates to a raw material transfer device for yellow phosphorus production with high safety. Background Art

[0002] Phosphorus chemical enterprises, as an important part of the chemical industry, have a very high dependence on raw materials in the production process. Especially for the key raw material of phosphate rock, the quality and processing technology of phosphate rock directly affect the quality and output of the final product. In the processing stage of phosphate rock, it is necessary to transfer the phosphate rock into a screening device to screen out the powder and then send it into a proportioning hopper for feeding into the smelting furnace. The purpose of sorting is to remove the powder slag and impurities in the phosphate rock. If these impurities are not removed during the smelting process, they may affect the purity of the final product. Sorting usually adopts physical methods such as screening and ore washing to ensure that the phosphate rock entering the smelting furnace reaches a certain purity.

[0003] In the conveying equipment in the related fields, when the raw materials fall from a high place, it is easy to cause deformation of the hopper and conveyor belt structures, affecting the service life. And the particulate phosphorus powder generated during transportation is easy to accumulate in the gaps, resulting in blockage of the screening mesh at the subsequent screening end. The traditional powder removal system is mostly an independent negative pressure device, and the powder removal efficiency depends on the fan control, and the powder cannot be recycled online, so there is room for improvement. Summary of the Invention

[0004] The purpose of the present invention is to provide a raw material transfer device for yellow phosphorus production with high safety to solve the problem of inconvenient dust cleaning during the transportation of yellow phosphorus.

Penetration grooves corresponding to the material dropping grooves are opened at the top of the sieve plate, and the sieve plate is slidably connected to the inner cavity of the scraper body. The material dropping grooves penetrate through the two cavities on both sides, and the penetration grooves are communicated with the material dropping grooves by moving the sieve plate.

[0013] As a further description of the above technical solution:

[0014] Wedges are connected to both sides of the top of the sieve plate. The cross-sectional shape of the wedge is triangular. Three fixing members are connected to both sides of the top of the scraper body, and extrusion rollers are slidably connected to the fixing members corresponding to the tops of the wedges, and knocking rods are slidably connected to the other two fixing members;

[0015] Hole bodies are opened at the positions corresponding to the wedges on the top of the scraper body. The extrusion rollers are slidably connected to the hole bodies. Force receiving blocks are connected to the ends of the knocking rods and the extrusion rollers away from the scraper body. The bottom of the braking member is wavy. After the conveyor belt drives the scraper body and the force receiving blocks to move to the bottom of the braking member, the extrusion rollers and the knocking rods are driven to reciprocate by the bottom side of the braking member;

[0016] Third springs are sleeved on the outside of the knocking rods and the extrusion rollers. The third springs are respectively connected to corresponding positions on the fixing members and one side of the force receiving blocks at corresponding positions.

[0017] As a further description of the above technical solution:

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, through the designed powder removal mechanism, when the force receiving block contacts the waveform structure at the bottom of the braking member, the downward movement of the force receiving block can drive the movement of the sieve plate. The movement of the sieve plate can drive the penetration groove to communicate with the material dropping groove of the scraper body. The powder accumulated on the top of the scraper body can move to the top of the discharge plate in the conveyor belt frame through the opened penetration groove and the material dropping groove. Moreover, the opening and closing of the sieve plate can be linearly related to the conveyor belt speed, improving the intelligent dust removal and screening effect. And compared with the traditional scraper, the integrated assembly of the sieve plate and the scraper body can improve the energy absorption of the material dropping impact, and cooperate with the buffer mechanism to improve the discharging stability and extend the service life, so as to improve the stability and high safety of the raw material rotation.

[0027] 2. In the present invention, through the designed buffer mechanism, when the material is dropped into the hopper by an external crane or forklift, the material can contact the buffer plate in the hopper. The buffer plate can pull the external first spring through the movement of the sliding rod in the sliding hole. The first spring can absorb the falling buffer. And when the buffer roller is squeezed, it can drive the lateral movement of the bushing. The lateral movement of the bushing can push the moving plate to move through the rotating pair. The movement of the moving plate can squeeze the external first telescopic rod. The first telescopic rod can absorb the lateral impact of the buffer roller through the external second spring, which is beneficial to improve the falling stability through the vertical buffer and lateral buffer of the buffer plate, avoid the resonance of the rigid structure of the conveyor belt caused by the impact, and improve the conveying stability.

[0028] 3. In the present invention, through the designed sealing mechanism, the sealing seat can close the clearance of the empty groove, so as to facilitate ensuring the sealing effect on the side of the scraper body when the scraper body is not in contact with the braking member, and the scraping strip can sweep away the residual dust in the wavy grooves at the bottom of the braking member through contact with the surface of the braking member, avoiding the influence on the unfolding of the sieve plate after the grooves of the braking member are filled, so as to improve the continuous utilization effect.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to 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.

[0047] Please refer to Figures 1 - 15 , the present invention provides a technical solution: a raw material transfer device for yellow phosphorus production with high safety, including a conveyor belt 1. A hopper 2 is provided on the feeding port side of the conveyor belt 1. A buffer mechanism 3 is installed in the hopper 2 to buffer the impact of the falling material. The conveyor belt 1 includes a frame and a plurality of scraper bodies 5, and a powder removal mechanism 6 is installed in the scraper body 5. The powder removal mechanism 6 intermittently opens the material dropping groove at the top of the scraper body 5. A plurality of braking members 4 are installed on one side of the conveyor belt 1 frame in the advancing direction of the material after the material drops from the hopper 2, and the braking members 4 control the movement of the powder removal mechanism 6 in the scraper body 5;

[0048] The buffer mechanism 3 includes a plurality of buffer rollers 301. Track grooves 311 are sleeved on the outer sides of both ends of the plurality of buffer rollers 301. Opposing buffer plates 302 are slidably connected to the outside of the buffer rollers 301. Sleeve bushes 305 are sleeved on the outer sides of both sides of the buffer rollers 301. Moving plates 307 are connected to both sides of the sleeve bushes 305 through rotating pairs 306. A first telescopic rod 308 is connected to one side of the moving plate 307. The other end of the first telescopic rod 308 is connected to a fixing plate 310. A second spring 309 is sleeved on the outside of the first telescopic rod 308. Both ends of the second spring 309 are connected to corresponding positions on one side of the fixing plate 310 and the moving plate 307 respectively.

[0049] A plurality of sliding rods 303 are arranged between the buffer plates 302 on both sides. The sliding rods 303 pass through sliding holes opened at corresponding positions of the buffer rollers 301. First springs 304 are sleeved on the outer sides of both ends of the sliding rods 303 located outside the buffer rollers 301. Both ends of the first springs 304 are connected to corresponding positions on one side of the buffer plates 302 and the outside of the buffer rollers 301 respectively.

[0050] Specifically: Through the designed buffer mechanism 3, when the material is lowered into the hopper 2 by an external crane or forklift, the material can contact the buffer plate 302 in the hopper 2. The buffer plate 302 can traction the external first spring 304 through the movement of the sliding rod 303 in the sliding hole. The first spring 304 can absorb the buffer of the falling material and improve the stability of the falling material guidance. And when the buffer roller 301 is squeezed, it can drive the sleeve bush 305 to move laterally. The lateral movement of the sleeve bush 305 can push the moving plate 307 to move through the rotating pair 306. The movement of the moving plate 307 can squeeze the external first telescopic rod 308. The first telescopic rod 308 can absorb the lateral impact of the buffer roller 301 through the external second spring 309, which is beneficial to improving the falling stability through the vertical buffer and lateral buffer of the buffer plate 302;

[0051] Through the designed rotating pair 306, the offset energy consumption can be carried out through the rotation of the components on both sides along the same axis, improving the anti-impact effect.

[0052] Please refer to Figures 2 - 6 and Figure 15 The powder removing mechanism 6 includes a sieve plate 601. Penetration grooves 602 corresponding to the falling material grooves are opened at the top of the sieve plate 601. The sieve plate 601 is slidably connected to the inner cavity of the scraper main body 5. The falling material groove penetrates through the cavities on both sides. The penetration grooves 602 are communicated with the falling material grooves through the movement of the sieve plate 601;

[0053] Both sides of the top of the sieve plate 601 are connected with wedge blocks 603. The cross-sectional shape of the wedge block 603 is triangular. Both sides of the top of the scraper body 5 are connected with three fixing pieces 610. And an extrusion roller 604 is slidably connected in the fixing piece 610 corresponding to the top of the wedge block 603, and a knocking rod 609 is slidably connected in the other two fixing pieces 610;

[0054] A hole body is formed at the position of the scraper body 5 corresponding to the wedge block 603 at the top. The extrusion roller 604 is slidably connected in the hole body. Force receiving blocks 606 are connected to one ends of the knocking rod 609 and the extrusion roller 604 away from the scraper body 5. The bottom of the braking member 4 is wavy. After the conveyor belt 1 drives the scraper body 5 and the force receiving block 606 to move to the bottom of the braking member 4, the bottom side of the braking member 4 drives the extrusion roller 604 and the knocking rod 609 to reciprocate;

[0055] A third spring 605 is sleeved outside the knocking rod 609 and the extrusion roller 604. The third springs 605 are respectively connected to the corresponding positions on one side of the fixing piece 610 and the force receiving block 606 at the corresponding positions;

[0056] A plurality of second telescopic rods 607 are connected to one side of the sieve plate 601 along the width direction. The second telescopic rods 607 are connected to the inner side of the cavity of the scraper body 5. A fourth spring 608 is sleeved outside the second telescopic rods 607. Both ends of the fourth spring 608 are respectively connected to the corresponding positions on one side of the sieve plate 601 and the inner cavity of the scraper body 5.

[0057] Among them, a discharge plate 8 is connected to the inner side of the frame of the conveyor belt 1 corresponding to the bottom side of the braking member 4. The discharge plate 8 is located between the two scraper bodies 5;

[0058] Specifically: through the designed powder removal mechanism 6, when the sprocket of the conveyor belt 1 drives the scraper body 5 to move, the movement of the scraper body 5 can drive the force-bearing block 606 at the top to the bottom side of the braking member 4 in the powder screening section. At this time, when the force-bearing block 606 contacts the corrugated structure at the bottom of the braking member 4, the protruding part of the braking member 4 can squeeze the force-bearing block 606 to move downward. The downward movement of the force-bearing block 606 can drive the extrusion roller 604 to move downward. The downward movement of the extrusion roller 604 can cause the extrusion wedge 603 to move horizontally through the extrusion. The horizontally moving wedge 603 can drive the sieve plate 601 to move in the cavity of the scraper body 5. The movement of the sieve plate 601 can drive the penetration groove 602 to communicate with the material discharge groove of the scraper body 5. At this time, the powder accumulated on the top of the scraper body 5 can move to the top of the discharge plate 8 within the frame of the conveyor belt 1 through the opened penetration groove 602 and the material discharge groove. At this time, the powder can be guided by the inclination angle of the discharge plate 8 to the outside of the conveyor belt 1 for recycling. It is beneficial to make the powder slag and dust on the surface of the material fully precipitate on the top of the scraper body 5 through the vibration of the scraper body 5 during transportation, and trigger the sieve plate 601 to open the penetration groove 602 when running to the slag discharge section, so as to realize the pre-screening treatment of the dust on the surface of the ore during the transportation of yellow phosphorus raw ore, avoid excessive accumulation of filter powder affecting the subsequent powder screening efficiency, and compared with the traditional scraper, it can improve the energy absorption of the material falling impact through the integrated assembly of the sieve plate 601 and the scraper body 5, avoid the influence of the opening of the penetration groove 602 and the material discharge groove on the falling impact resistance effect, improve the service life, and cooperate with the buffer mechanism 3 to improve the discharging stability and extend the service life, so as to improve the stability and high safety of the raw material rotation;

[0059] Further, when the force-bearing block 606 contacts the braking member 4, the force-bearing block 606 can drive the extrusion roller 604 at the corresponding position at the bottom to move. When the force-bearing block 606 moves to the wavy concave section, the external third spring 605 can use its own elastic force to drive the force-bearing member and the reset of the knocking rod 609. It is beneficial to realize the reciprocating knocking of the knocking rod 609 through the elastic force of the third spring 605, which is convenient to assist the vibration of the knocking rod 609 to make the powder fully fall from the scraper body 5 into the discharge plate 8 after the penetration groove 602 is opened, and improve the powder screening and conveying efficiency.

[0060] Guide strips 9 are connected to both sides of the inner cavity of the material discharge groove at the top of the scraper body 5. The cross-sectional shape of the guide strip 9 is triangular. The guide strip 9 guides the material into the penetration groove 602. A sealing gasket is connected to the bottom of the sieve plate 601 at the position corresponding to the penetration groove 602;

[0061] Specifically, through the designed guide strip 9, it can avoid particles from getting stuck in the gap of the material discharge groove through the setting of the guide strip 9, and when the horizontally moving sieve plate 601 moves, it can extrude the granular material upward through the flexible contact of the guide strip 9 to avoid the generation of broken materials caused by shearing the particles and improve the transfer and conveying effect;

[0062] Wherein, the guiding bars 9 on both sides form a trapezoidal guiding space in the blanking chute;

[0063] Please refer to Figure 7 and Figure 8 As shown, the sealing mechanism 7 includes a sealing seat 701 which is connected in an empty groove laterally opened on the vertical part of the scraper body 5. A plurality of brush bars 702 are connected in the inner cavity of the sealing seat 701 along the width direction, and the height of the inner cavity of the empty groove is greater than the height of the braking member 4 to prevent interference between the scraper body 5 and the braking member 4 when the scraper body 5 moves;

[0064] Specifically: through the designed sealing mechanism 7, the sealing seat 701 can seal the gap of the empty groove to facilitate ensuring the sealing effect on the side of the scraper body 5 when the scraper body 5 is not in contact with the braking member 4, and the scraping bar can sweep away the dust remaining in the wavy grooves at the bottom of the braking member 4 through contact with the surface of the braking member 4, avoiding affecting the unfolding of the sieve plate 601 after the grooves of the braking member 4 are filled, so as to improve the continuous utilization effect.
