Description

Technical Field

[0001] The invention relates to the technical field of screw conveying devices, and in particular to a fully enclosed sintering mixing system pollutant zero-emission screw conveying device. Background Art

[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve transportation. It can transport horizontally, inclined or vertically. It has a simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation.

[0003] For example, the patent document with the publication number CN113415600A discloses a high-efficiency screw conveyor with good dustproof sealing performance, including a base, a motor, a funnel, an anti-blocking mechanism and a cover box. The front and rear sides of the base are fixed with driving rollers, the right side of the connecting frame is provided with a support plate, the right side of the support plate is provided with a hydraulic cylinder, the top of the hydraulic cylinder is connected to the top support frame through a piston rod, the feeding channel is placed on the bracket, the inner side of the feeding channel is rotatably connected with a screw rod, the anti-blocking mechanism is fixed on the right side of the lower end face of the feeding channel, and the top of the anti-blocking mechanism is connected with the discharge port. The high-efficiency screw conveyor with good dustproof sealing performance can pass the material into the funnel after adjusting the angle of the feeding channel and locking the feeding channel. After the material enters the feeding channel through the feed channel, the screw rod rotates to facilitate the material to move to the right, and the material is discharged through the discharge port and the discharge channel in turn. The sealing performance of the feeding channel is good, and the dustproof effect can be achieved.

[0018] 1. The present invention compacts the sintering mixture through the extrusion mechanism, reducing dust generated by material collision and friction. The compacted mixture helps to improve the efficiency of the sintering process because the closely arranged particles can promote the uniform distribution of heat and gas, thereby improving the physical and chemical properties of the sintered ore. The compacted sintering mixture generates less debris and dust during the processing process, reducing the cleaning work of equipment and the ground.

[0019] 2. The feeding mechanism of the present invention can reduce the adhesion of the sintered mixture, and can destroy the static friction between the sintered mixture and the inner wall of the shell through vibration, thereby preventing the material from sticking and agglomerating, and ensuring that the material flows smoothly into the feeding mechanism. The pushing mechanism can accelerate the flow of the sintered mixture by increasing the conveying speed, and the vibration of the internal device of the pushing mechanism can loosen the sintered mixture adhering to the surface of the mechanism.

In addition, the combined effect of the rapid rotation of the extrusion impeller and the reduced space effectively compacts the sintered mixture, improves the compactness of the material, and is beneficial to the subsequent sintering process. The inclined plate is extruded when the sintered mixture passes through, further performing a secondary extrusion on the material, thereby increasing the density and strength of the material.

[0021] 4.

The inclined arc design of the inner wall of the feed hopper reduces the probability of material adhesion, makes the sintering mixture easier to slide, and avoids material residue and agglomeration. The inclined design of the feed hopper helps to control the falling speed of the material, making it more uniform, and avoiding the sudden outflow of a large amount of material or interruption of flow.

DETAILED DESCRIPTION

[0043] 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Example 1, Reference Figures 1 to 19 A fully enclosed sintering mixing system pollutant zero-emission spiral conveying device shown in the figure includes a first support frame 1, a driving motor 2 is arranged inside the first support frame 1, a first gear 3 is arranged at the output end of the driving motor 2, a feeding mechanism 6 is arranged at the upper end of the first support frame 1, a second gear 5 is arranged on one side of the feeding mechanism 6, a conveyor belt 4 is jointly sleeved on the outer surfaces of the second gear 5 and the first gear 3, a feeding mechanism 7 for clearing blocked materials is arranged at the upper end of the feeding mechanism 6, a pushing mechanism 8 for pushing materials is arranged on one side of the feeding mechanism 6, a cleaning mechanism 9 for cleaning the conveying pipeline is arranged on the upper part of the outer surface of the pushing mechanism 8, and an extruding mechanism 10 for extruding materials into blocks is arranged at the bottom of the pushing mechanism 8.

[0045] It is worth noting that the sintered mixture is a variety of raw materials used in the steel industry to convert fine iron ore powder and other auxiliary materials into more solid and easy-to-handle bulk materials through the sintering process. When conveying the sintered mixture, the mixture is first poured into the feeding mechanism 7, and the mixture enters the feeding mechanism 6 through the feeding mechanism 7. Since the sintered mixture is highly viscous and easily generates dust, in order to prevent the sintered mixture from being blocked in the feeding mechanism 7, the feeding mechanism 7 is set to adopt a torsion arc structure and a vibration setting to prevent the sintered mixture from being blocked in the feeding mechanism 7, and the feeding mechanism 6 can quickly push the sintered mixture into the pushing mechanism 8, and the feeding mechanism 6 can prevent the sintered mixture from generating a lot of dust during the transportation process;

[0046] When the sintered mixed material enters the pushing mechanism 8, the pushing mechanism 8 can accelerate the conveying of the mixed material. When the sintered mixed material inside the pushing mechanism 8 needs to be cleaned, the cleaning mechanism 9 can spray a strong airflow or high-pressure water to clean the inside of the pushing mechanism 8. The device arranged inside the pushing mechanism 8 can clean the sticky sintered mixed material inside the pushing mechanism 8 through the vibration generated by the impact.

[0047] The arc shape of the feeding mechanism 7 can reduce the adhesion of the sintered mixture, and can destroy the static friction between the sintered mixture and the inner wall of the shell through vibration, thereby preventing the material from sticking and agglomerating, and ensuring that the material flows smoothly into the feeding mechanism.

[0048] The pushing mechanism 8 can speed up the flow of the sintering mixture by increasing the conveying speed, and the vibration of the internal device of the pushing mechanism 8 can loosen the sintering mixture adhering to the surface of the mechanism.

[0049] When the sintered mixture is pushed out from the pushing mechanism 8, it will enter the extruding mechanism 10, and the extruding mechanism 10 will squeeze the sintered mixture so that the sintered mixture is squeezed tightly and then pushed out, ensuring that when the sintered mixture falls, it will not cause a lot of dust to be generated due to looseness.

[0050] Among them, by compacting the sintering mixture and reducing the dust generated by material collision and friction, the compacted mixture helps to improve the efficiency of the sintering process because the tightly arranged particles can promote the uniform distribution of heat and gas, thereby improving the physical and chemical properties of the sintered ore. The compacted sintering mixture produces less debris and dust during the processing process, reducing the cleaning work of equipment and the ground.

[0051] The feeding mechanism 7 includes a feeding hopper 71, the inner wall of which is provided with a second supporting frame 72, the interior of the second supporting frame 72 is provided with a top shell 73, the lower end of the top shell 73 is provided with a bottom cover 74, the bottom of the outer surface of the bottom cover 74 is provided with a rod 75, the interior of the bottom cover 74 is provided with a vibration motor 76, and the feeding hopper 71 is fixedly mounted on the upper end of the feeding pipe 61.

[0052] It is worth noting that the sintered mixture first enters the inside of the feed hopper 71, and then the vibration motor 76 inside the bottom cover 74 applies vibration force to the sintered mixture accumulated inside the feed hopper 71 through vibration, so as to prevent the sintered mixture from being blocked in the feed hopper 71 due to high viscosity or high friction between particles of the mixture, and the rod 75 is arranged to reach deep into the inside of the feed hopper 71 to increase the transmission force of the vibration of the vibration motor 76;

[0053] The feed hopper 71 is provided with Figure 6 As shown in the shape, when the vibration motor 76 vibrates and transmits force to the feed hopper 71 through the second support frame 72, the inner wall of the feed hopper 71 is in an inclined arc shape, which can prevent the sintered mixed materials from sticking together.

[0054] The vibration motor 76 can effectively break the static friction and adhesion between the sintered mixed material particles through vibration, prevent the material from being blocked in the feed hopper 71, and ensure that the material falls smoothly.

[0055] The rod 75 penetrates deep into the feed hopper 71, which increases the conduction of vibration energy, makes the vibration effect more uniform, and further improves the fluidity of the sintering mixture.

[0056] In addition, the inclined arc design of the inner wall of the feed hopper 71 reduces the probability of material adhesion, making it easier for the sintered mixture to slide down, avoiding material residue and agglomeration. The inclined design of the feed hopper 71 helps to control the falling speed of the material, making it more uniform, and avoiding sudden large-scale outflow or interruption of the material.

[0057] The feeding mechanism 6 includes a feeding pipe 61, which is fixedly mounted on the upper end of the first support frame 1, a barrel 62 is provided on one side of the feeding pipe 61, a shaft 65 is rotatably mounted inside the feeding pipe 61, one end of the shaft 65 is fixedly connected to the second gear 5, a spiral sheet 66 is provided on the outer surface of the shaft 65, and a plurality of blade tips 67 are inlaid on the outer surface of the spiral sheet 66;

[0058] A plurality of mounting rings 63 are disposed on the outer surface of the barrel 62 , and a magnetic ring 64 is disposed between every two mounting rings 63 .

[0059] It is worth mentioning that the sintered mixture falls into the feed pipe 61 through the feed hopper 71, and the driving motor 2 drives the first gear 3 to rotate through the output end, and the first gear 3 drives the second gear 5 to rotate through the conveyor belt 4, and the second gear 5 drives the shaft 65 to rotate, and the shaft 65 drives the spiral piece 66 to rotate, and the spiral piece 66 drives the blade tip 67 to rotate, and the rotation of the spiral piece 66 and the blade tip 67 pushes the sintered mixture in the feed pipe 61 into the barrel 62, and the magnetic ring 64 in the mounting ring 63 is in the shape of a circular ring. When the sintered mixture passes through the barrel 62, the magnetic force generated by the magnetic ring 64 can absorb the iron filings and dust in the sintered mixture and adsorb it on the inner wall of the barrel 62, and when the spiral piece 66 rotates, it drives the blade tip 67 to scratch the inner wall of the barrel 62 to push the sintered mixture, thereby preventing the iron filings and dust from floating out from the mouth of the feed pipe 61.

[0060] Among them, the driving motor 2 drives the transmission chain of the first gear 3, the second gear 5 and the shaft 65, thereby realizing the continuous rotation of the spiral blade 66 and the blade tip 67, ensuring the stable and efficient transportation of the sintered mixture, and the setting of the magnetic ring 64 can absorb the iron filings and dust in the sintered mixture. While pushing the sintered mixture, the blade tip 67 can also scrape off the iron filings and dust on the inner wall of the barrel 62 to prevent them from generating dust as the material flows.

[0061] Example 2, Reference Figures 9 to 16 The pushing mechanism 8 shown includes a mounting cylinder 81 and a discharge pipe 87. The mounting cylinder 81 is fixedly connected to the barrel 62. A sealing disk 80 is provided at one end of the mounting cylinder 81. One end of the discharge pipe 87 is fixedly connected to the shaft rod 65. The other end of the discharge pipe 87 passes through the sealing disk 80 and is fixedly installed with a meshing gear 82. A plurality of leakage holes 84 distributed at equal intervals are provided on the upper portion of the outer surface of the mounting cylinder 81. A slide block 83 is provided on the outer surface of the mounting cylinder 81. A base frame 86 is provided at the bottom of the outer surface of the mounting cylinder 81. A through pipe 817 communicating with the interior of the mounting cylinder 81 is provided on one side of the bottom of the outer surface of the mounting cylinder 81.

[0062] It is worth noting that the rotation of the shaft 65 drives the discharge pipe 87 to rotate, and the discharge pipe 87 drives the pusher blade 85 to rotate, and the pusher blade 85 is arranged in a Figures 11 to 13 As shown in the shape, the shape design of the push rotor blade 85 can reduce the pushing resistance and increase the overall wear resistance of the push rotor blade 85 during the process of pushing the sintering mixture.

[0063] Two pushing rotor blades 85 are arranged around the outer surface of the discharge pipe 87, and a plurality of equally spaced spacer rings 812 are arranged on the inner wall of the discharge pipe 87. An axial core rod 88 is slidably installed inside the plurality of spacer rings 812. A plurality of equally spaced top rings 89 are arranged on the outer surface of the axial core rod 88, and the top ring 89 is located between every two spacer rings 812. A plurality of equally spaced first springs 811 are sleeved on the outer side of the axial core rod 88, and the first spring 811 is located between the spacer rings 812 and the top ring 89.

[0064] It is worth mentioning that when it is necessary to clean the sintered mixture stuck on the surface of the push vane 85, the shaft core rod 88 is pulled to drive the top ring 89 to slide inside the discharge pipe 87, and the top ring 89 squeezes the first spring 811 to contract. When the first spring 811 rebounds, it drives the top ring 89 to hit the spacer ring 812. The spacer ring 812 vibrates after being hit, and the vibration force will be transmitted to the push vane 85 through the discharge pipe 87, and the sintered mixture adsorbed on the surface of the push vane 85 will fall off due to the vibration force.

[0065] Among them, the special shape design of the pushing impeller 85 can reduce the friction between the impeller and the sintered mixture, thereby reducing the resistance during the pushing process. By optimizing the shape of the pushing impeller 85, the flow characteristics of the sintered mixture can be improved, preventing the material from agglomerating or clogging during the transportation process, thereby ensuring a continuous and stable material flow.

[0066] Furthermore, by pulling the shaft core rod 88 and utilizing the elastic force of the spring and the vibration of the spacer ring 812, the sintered mixture adhering to the surface of the pusher blade 85 can be effectively removed without disassembling the equipment, thereby greatly improving the cleaning efficiency.

[0067] The cleaning mechanism 9 includes an arc cover plate 91, which is slidably installed inside the slide block 83. The inner wall of the arc cover plate 91 is provided with a plurality of arc holes 92 distributed at equal intervals. The plurality of arc holes 92 correspond to the positions of the leakage holes 84. The interiors of the plurality of arc holes 92 are each provided with a mounting shell 93, and the interiors of the arc holes 92 are each provided with a through pipe 94 that penetrates each other, and the interiors of the plurality of mounting shells 93 are each provided with an inclined plate 95.

[0068] Among them, when it is necessary to clean the push rotor blade 85 and the mounting cylinder 81, the arc cover plate 91 is pushed to slide inside the slide block 83 so that the arc hole 92 and the push rotor blade 85 overlap each other, and the through pipe 94 sprays air flow or water flow through the mounting shell 93 and enters the mounting cylinder 81 through the guidance of the inclined plate 95. When the mounting cylinder 81 is cleaned, the arc cover plate 91 is pushed to make the push rotor blade 85 misaligned with the arc hole 92, so that the interior of the mounting cylinder 81 can be sealed.

[0069] Example 3, Reference Figures 17 to 19The extrusion mechanism 10 shown includes a conical shell 104, the inner wall of which is provided with an axis frame 107, a transmission rod 103 is rotatably installed inside the axis frame 107, the conical shell 104 is fixedly installed at the bottom of the feed pipe 817, one end of the transmission rod 103 passes through the conical shell 104 and the base frame 86 and is fixedly installed with a transmission gear 101, which meshes with the meshing gear 82.

[0070] The outer surface of the transmission rod 103 is provided with an extrusion vane 106, one end of the cone shell 104 is provided with a tube 105, and the outer surface bottom of the tube 105 is provided with a discharge port 108;

[0071] It is worth mentioning that the sintered mixture pushed from the inside of the mounting cylinder 81 is pushed into the inside of the feed pipe 817, and the discharge pipe 87 drives the transmission gear 101 to rotate when it rotates. The transmission gear 101 rotates to push the sintered mixture inside the feed pipe 817 into the cone shell 104. The cone shell 104 is conical in shape, and the extrusion vane 106 fits the inner wall of the cone shell 104. As shown, when the transmission rod 103 rotates to drive the extrusion vane 106 to rotate, the space is constantly reduced and the design of the transmission gear 101 makes the rotation speed of the transmission rod 103 faster than the rotation speed of the discharge pipe 87, so the extrusion vane 106 can quickly push the sintered mixture inside the extrusion cone shell 104.

[0072] Two slide grooves 111 are symmetrically arranged on the inner wall of the bobbin 105, and an inclined plate 109 is slidably installed inside the two slide grooves 111. A guide rod 102 is arranged in the middle of one end of the inclined plate 109, and one end of the guide rod 102 passes through the bobbin 105. A second spring 110 is sleeved on the outer surface of the guide rod 102 and located inside the bobbin 105.

[0073] When the extrusion impeller 106 pushes the mixture into the interior of the barrel 105, the sintered mixture hits the inclined plate 109, thereby pushing the inclined plate 109 to squeeze the second spring 110 to contract, and the inclined plate 109 slides inside the slide groove 111. Because the inclined plate 109 is in the shape of a disc, after the sintered mixture hits the inclined plate 109, the sintered mixture is squeezed again due to the resistance brought by the inclined plate 109, and the cross-section of the inclined plate 109 is an inclined step surface, which guides the extruded sintered mixture into the discharge port 108.

[0074] Among them, the conical shape design of the cone shell 104, combined with the rotation of the extrusion impeller 106, allows the sintered mixture to be gradually extruded as it passes through, thereby improving the density of the material and reducing dust generation during subsequent processing. In addition, the combined effect of the rapid rotation of the extrusion impeller 106 and the reduction in space effectively compacts the sintered mixture, improves the compactness of the material, and is beneficial to the subsequent sintering process.

[0075] The inclined plate 109 is squeezed when the sintered mixture passes through, which further performs secondary squeezing on the material, increasing the density and strength of the material. The inclined stepped surface design of the inclined plate 109 not only plays an extrusion role, but also plays a guiding role, ensuring that the sintered mixture can smoothly enter the discharge port 108 and avoiding material blockage or overflow.

[0076] Furthermore, the provision of the second spring 110 allows the inclined plate 109 to have a certain elastic movement, and can adapt to sintering mixtures of different densities and quantities.

[0077] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
