At the same time, in the stable production stage, although the quality of the materials produced is relatively stable, fine management and control are still needed. However, the existing conveying device lacks an effective shunt device, making it difficult to effectively distinguish and discharge the waste materials from the normal production materials, which directly leads to the mixing of waste materials and normal materials during the conveying process.

[0003] Once these mixed materials enter the subsequent processing flow, it will have a serious negative impact on the quality of the entire product batch. For example, the mixing of waste materials may cause a decrease in product performance, even causing quality problems, leading to an increase in product rejection rate, causing economic losses and reputation damage to the enterprise.

In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0041] In the description of the utility model, it should be noted that, unless otherwise specified and limited, the terms "mounting", "splicing", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0042] The utility model discloses a kind of rotary kiln vertical feeding cooling conveying devices for shunting. Figures 1 to 5 , describe a kind of rotary kiln vertical feeding cooling conveying devices for shunting of the utility model embodiment.

[0043] A kind of rotary kiln vertical feeding cooling conveying device for shunting, including shunt 1, transfer bin 2, vertical feeder 3 and water cooling component 4;

[0044] The input end of the shunt 1 is communicated with the rotary kiln, the first output end of the shunt 1 is communicated with the input end of the transfer bin 2, the second output end of the shunt 1 is communicated with the outside, the shunt 1 is provided with raw material switching valve 5 at the junction of the first output end and the second output end, and the raw material switching valve 5 is used to block the first output end or the second output end of the shunt 1;

[0045] The output end of the transfer bin 2 is connected with the input end of the vertical feeder 3, and the output end of the vertical feeder 3 is connected with the outside.

[0046] The water cooling component 4 is annularly arranged on the vertical feeder 3 and the transfer bin 2, and the water cooling component 4 is used to cool the vertical feeder 3 and the transfer bin 2.

[0047] The output end of the rotary kiln is connected with the flow divider 1, so when it is necessary to process trial burning waste materials, the raw material switching valve 5 quickly seals the first output end, so that the waste materials are directly discharged to the outside through the second output end, preventing the trial burning waste materials from entering the subsequent key production process.

[0048] For normal production materials, the raw material switching valve 5 quickly seals the second output end, so that the normal production materials are smoothly introduced into the transfer bin 2 from the first output end, thereby realizing rapid diversion of the materials and ensuring the orderly transmission of the materials and the continuity of the subsequent processing.

[0049] The transfer bin 2 can receive the materials from the flow divider 1, so that the materials have a temporary storage and stabilization process before entering the vertical feeder 3, thereby ensuring that the vertical feeder 3 can continuously and stably receive the materials, avoiding problems such as uneven feeding or interruption due to fluctuations in the supply of front-end materials, guaranteeing the continuity and stability of the entire feeding process, and being beneficial to improve the overall operation stability and production efficiency of the rotary kiln.

[0050] The vertical feeder 3 adopts a vertical conveying mode, which can realize a greater conveying height improvement under the same floor area compared with the traditional inclined or horizontal conveying mode, effectively saving the space occupation of the device.

[0051] The water cooling assembly 4 surrounds the transfer bin 2 and can maintain the temperature of the materials in the bin within a suitable range, preventing the materials from deteriorating, caking and other phenomena due to heat accumulation. The water cooling assembly 4 surrounds the vertical feeder 3, and the cooling can prevent the materials from sticking to the conveying components due to high temperature, reducing the risk of equipment blockage and ensuring the smoothness and continuity of the feeding. At the same time, it also avoids the materials from continuing to react chemically or physically under high temperature, thereby ensuring the quality stability and performance consistency of the materials.

[0052] In the present scheme, through the flow divider 2, the vertical feeder 3 and the cooling assembly 4, the diversion and cooling treatment of the materials can be accurately and efficiently realized, perfectly solving the problems of the traditional rotary kiln, i.e. the conveying device cannot effectively divert the materials after outputting high-temperature materials, and the cooling efficiency is low.

[0053] The flow divider 1 comprises a vertical square channel 11, a first inclined square channel 12 and a second inclined square channel 13, the bottom of the vertical square channel 11, the top of the first inclined square channel 12 and the top of the second inclined square channel 13 are in communication with each other to form an active space of the switching valve, and the raw material switching valve 5 is used to seal the top of the first inclined square channel 12 or the top of the second inclined square channel 13.

[0054] The top of the vertical square channel 11 is an input end, the bottom of the first inclined square channel 12 is a first output end, the bottom of the second inclined square channel 13 is a second output end, and the bottom of the first inclined square channel 12 is in communication with the transfer bin 2.

[0055] The raw material switching valve 5 works in the active space formed by the communication of the three, when the raw material switching valve 5 blocks the top of the first inclined square channel 12, the material will flow out of the second output end, i.e. the bottom of the second inclined square channel 13, to quickly guide the material that does not meet the current production process requirements or needs other special treatment out of the way, avoiding the material from entering the subsequent key transfer bin 2, and preventing the bad material from interfering with the production process or affecting the product quality.

[0056] When the raw material switching valve 5 switches and blocks the top of the second inclined square channel 13, the material will be guided by the first inclined square channel 12 and slide obliquely to the input end of the transfer bin 2. The first inclined square channel 12 is obliquely arranged, which can realize relatively smooth sliding conveying by using the gravity of the material itself, so as to ensure that the material can be stably and efficiently transferred from the flow divider 1 to the transfer bin 2, reduce the problems such as material crushing or component separation caused by mechanical disturbance, and help to maintain the original characteristics and quality of the material.

[0057] The raw material switching valve 5 comprises a switching power member 51, a swing plate 52, a switching plate 53 and a switching shaft 54;

[0058] The switching shaft 54 is rotatably installed at the intersection of the first inclined square channel 12 and the second inclined square channel 13 of the flow divider 1, the bottom of the switching plate 53 is fixedly connected with the switching shaft 54, the top of the switching plate 53 abuts against the inner wall of the vertical square channel 11, and the end of the switching shaft 54 penetrates out of the flow divider 1;

[0059] The switching power member 51 is rotatably installed on the outer side wall of the second inclined square channel 13, the driving end of the switching power member 51 is hingedly connected with one end of the swing plate 52, and the other end of the swing plate 52 is fixedly connected with the switching shaft 54;

[0060] When the top of the switching plate 53 abuts against the side wall of the vertical square channel 11 close to the second inclined square channel 13, the switching plate 53 blocks the second output end; when the top of the switching plate 53 abuts against the side wall of the vertical square channel 11 close to the first inclined square channel 12, the switching plate 53 blocks the first output end.

[0061] It is worth mentioning that the switching power element 51 is a cylinder. When the switching power element 51 is started, the piston rod of the switching power element 51 extends outward, thereby driving the swing plate 52 to rotate, and the swing plate 52 rotating can drive the switching shaft 54 and the switching plate 53 to rotate, so that the top of the switching plate 53 abuts against the side wall of the vertical square channel 11 close to the first inclined square channel 12. At this time, the switching plate 53 blocks the first output end, so that the second output end is in communication with the input end, and it can be ensured that the trial waste can flow to the outside under the guidance of the second inclined square channel 13.

[0062] When the switching power element 51 is started in the opposite direction, the piston rod of the switching power element 51 retracts inward, thereby driving the swing plate 52 to rotate, and the swing plate 52 rotating can drive the switching shaft 54 and the switching plate 53 to rotate, so that the top of the switching plate 53 abuts against the side wall of the vertical square channel 11 close to the second inclined square channel 13. At this time, the switching plate 53 blocks the second output end, so that the first output end is in communication with the input end, and it can be ensured that the normally produced material can flow to the intermediate warehouse 2 under the guidance of the first inclined square channel 12.

[0063] In the present scheme, the extension and retraction of the piston rod in the switching power element 51 can quickly realize the switching of the output end in the flow divider 1, so that the whole raw material switching valve 5 can complete the switching of the material flow in a short time, and the flexibility and timeliness of the production process are improved.

[0064] The vertical feeder 3 comprises a conveying bin 31, a conveying screw 32 and a power assembly 33.

[0065] The bottom of the conveying bin 31 is in communication with the output end of the intermediate warehouse 2, the conveying bin 31 is vertically installed on the top of the intermediate warehouse 2, and the conveying screw 32 is vertically installed in the inside of the conveying bin 31.

[0066] The conveying screw 32 comprises a central shaft 321 and a propeller blade 322, the propeller blade 322 is annularly arranged on the outside of the central shaft 321, the bottom of the central shaft 321 is rotationally connected with the bottom wall of the intermediate warehouse 2, the top of the central shaft 321 rotationally penetrates through the top wall of the conveying bin 31, the power assembly 33 is fixedly connected with the central shaft 321, and the power assembly 33 is used to drive the central shaft 321 to rotate.

[0067] The water cooling assembly 4 is annularly arranged on the conveying bin 31 and the intermediate warehouse 2.

[0068] The propeller blade 322 is annularly arranged on the outside of the central shaft 321, when the power assembly 33 drives the central shaft 321 to rotate, the propeller blade 322 rotates, and an upward pushing force and a frictional force are generated on the material in the conveying bin 31, so that the material is gradually conveyed upward along the inner wall of the conveying bin 31.

[0069] The bottom of the central shaft 321 is rotationally connected with the bottom wall of the transfer bin 2, and the top of the central shaft 321 rotationally penetrates the top wall of the conveying bin 31, which can ensure the stability of the central shaft 321 during rotation, and reduce problems such as uneven material conveying or equipment failure caused by shaking of the central shaft 321.

[0070] The power assembly 33 comprises a feeding power component 331, a driving pulley 332, a transmission pulley 333 and a transmission belt 334.

[0071] The feeding power component 331 is installed at the top of the conveying bin 31, the output end of the feeding power component 331 is sleeved with the driving pulley 332, the top of the central shaft 321 is fixedly sleeved with the transmission pulley 333, and the transmission belt 334 is movably sleeved on the driving pulley 332 and the transmission pulley 333.

[0072] It is worth noting that the feeding power component 331 is a speed reducer. When the feeding power component 331 is started, the feeding power component 331 drives the driving pulley 332 to rotate, and the rotation of the driving pulley 332 can drive the transmission belt 334 to rotate. Since the transmission belt 334 is movably sleeved on the driving pulley 332 and the transmission pulley 333, the transmission belt 334 can drive the transmission pulley 333 to rotate. The transmission pulley 333 is coaxially arranged with the central shaft 321, so that the transmission pulley 333 can drive the central shaft 321 and the propeller blade 322 to rotate, thereby realizing vertical conveying of the material.

[0073] The water cooling assembly 4 comprises a cooling circulating pump 41, a first cooling pipeline 42, a communication pipeline 43 and a second cooling pipeline 44.

[0074] The first cooling pipeline 42 is annularly arranged outside the conveying bin 31, the second cooling pipeline 44 is annularly arranged outside the transfer bin 2, the top of the communication pipeline 43 and the top of the first cooling pipeline 42 are in communication with each other, the bottom of the communication pipeline 43 and the top of the second cooling pipeline 44 are in communication with each other, the output end of the cooling circulating pump 41 is in communication with the bottom of the first cooling pipeline 42, and the input end of the cooling circulating pump 41 is in communication with the top of the second cooling pipeline 44. The cooling circulating pump 41 is used for cooling and circulating water and externally conveying the circulating water.

[0075] The cooling circulating pump 41 first delivers the cooled circulating water to the bottom of the first cooling pipe 42. As the circulating water continues to be injected, the water level in the first cooling pipe 42 rises. At this time, the circulating water can fully and uniformly absorb the heat generated by the material during the vertical feeding process. Because the specific heat capacity of water is large, it can effectively take away a large amount of heat, thereby preventing the conveying bin 31 from structural deformation, material adhesion, and reduced conveying efficiency due to overheating.

[0076] When the water level of the circulating water in the first cooling pipe 42 is higher than the height of the connecting pipe 43, at this time, the heated circulating water in the first cooling pipe 42 flows smoothly to the top of the second cooling pipe 44 under the guidance of the connecting pipe 43, and then flows from top to bottom in the second cooling pipe 44 to the bottom of the transfer bin 2, thereby preliminarily cooling the transfer bin 2. At this time, as the circulating water in the connecting pipe 43 continues to be injected, the water level of the circulating water in the second cooling pipe 44 rises and cools the transfer bin 2 again.

[0077] Because the high-temperature material is first transferred and stored in the transfer bin 2, the temperature of the material in the transfer bin 2 is relatively high. When the circulating water that has absorbed the heat of the conveying bin 31 from the first cooling pipe 42 enters the second cooling pipe 44 to cool the transfer bin 2, the heated circulating water will not produce strong thermal shock in the contact moment due to the large water temperature gap with the high-temperature material, thereby causing uneven heating of the transfer bin 2. Uneven heating will cause uneven thermal stress of the transfer bin 2, which may cause structural deformation, cracking, and even damage of the bin body after long-term accumulation, seriously affecting the service life of the transfer bin 2 and the safety of material storage.

[0078] When the water level of the circulating water in the second cooling pipe 44 reaches a certain level, the circulating water flows into the cooling circulating pump 41 under the action of the cooling circulating pump 41, cools the circulating water, and then delivers the cooled circulating water to the first cooling pipe 42, thereby continuing the above-mentioned cooling circulation process.

[0079] The first cooling pipe 42 is spirally wound on the outside of the conveying bin 31, and the second cooling pipe 44 is spirally wound on the outside of the transfer bin 2.

[0080] In this scheme, the first cooling pipe 42 and the second cooling pipe 44 are both spirally wound for cooling.

[0081] The spiral structure can form a uniformly distributed cooling path on the outside of the conveying bin 31 and the transfer bin 2, ensuring that the heat is uniformly taken away from all directions. No matter which part of the material contacts the conveying bin 31 and the transfer bin 2 during the rising process, it can be in a relatively stable and uniform low-temperature environment.

[0082] The transfer bin 2 is an inverted square pyramid structure.

[0083] The inverted square pyramid shape enables the material to naturally and smoothly gather at the bottom under the action of gravity, and then be transported by the conveying screw 32 into the top output end of the conveying bin 31, avoiding the accumulation of the material in the bin, reducing the possibility of material residues, and effectively preventing problems such as deterioration, caking or blockage caused by material retention.

[0084] Embodiment 2

[0085] The scheme is basically the same as Embodiment 1, except that the first cooling pipe 42 is a hollow cylinder, the inner wall of the first cooling pipe 42 and the outer wall of the conveying bin 31 form a sealed first cooling space, and circulating water cools the high-temperature material in the conveying bin 31 in the first cooling space;

[0086] The second cooling pipe 44 is a hollow square frame, the inner wall of the second cooling pipe 44 and the outer wall of the transfer bin 2 form a sealed second cooling space, and circulating water cools the high-temperature material in the transfer bin 2 in the second cooling space.

[0087] The first cooling pipe 42 and the outer wall of the conveying bin 31 form a sealed first cooling space, so that the circulating water flows in this relatively closed and tightly fitted first cooling space, which can quickly take away the heat generated by the material in the conveying bin 31 due to friction, chemical reaction, etc., effectively preventing the material from softening, deforming or even damaging due to overheating of the conveying bin 31.

[0088] Similarly, the second cooling pipe 44 and the outer wall of the transfer bin 2 form a second cooling space, and the circulating water has high heat exchange capacity in the second cooling space. The circulating water directly contacts the wall of the transfer bin 2 and covers all areas of the wall, whether it is the bottom where the material is more accumulated or the part near the top, the heat generated can be uniformly transferred to the circulating water in time, so that the circulating water absorbs the heat in all directions, ensuring that the temperature of the material in the transfer bin 2 is uniform and stable.

[0089] The first cooling pipe 42 and the second cooling pipe 44 can also play a protective role, effectively resisting various impact forces from the outside, preventing damage to the conveying bin 31 and the transfer bin 2 caused by external impact, and prolonging the service life of the conveying bin 31 and the transfer bin 2.

[0090] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the explanations herein, other specific embodiments of the present application can be conceived by those skilled in the art without creative efforts, and these embodiments will all fall within the protection scope of the present application.
