Description

Technical Field

[0001] The present invention relates to the field of silicone synthesis reaction equipment, and specifically to a silicone synthesis system and method that uses dynamic steel ball flow heat exchange and self-cleaning. Background Art

[0002] The synthesis reaction of silicone (such as methylchlorosilane) is an exothermic reaction, and the reaction equation is: Therefore, a cooling device is often required in the fluidized bed reactor for synthesizing silicone.

[0003] Such as Figure 10 As shown, in the prior art, a heat exchange tube 7 is mostly arranged in the reactor 1, and a cold source is introduced into the heat exchange tube 7 to absorb the heat generated during the reaction process. During the reaction process, when the local exothermic heat is higher than the upper limit of the reaction temperature, there is still a certain amount of side reaction - methyl chloride dehydrogenates and dechlorinates to become carbon black. This side reaction product often adheres to the inner wall of the heat exchange tube and the inner wall of the reactor. The accumulation of carbon black leads to the deterioration of the heat dissipation conditions. And generally, the reactor wall is set as a double-layer structure, and heat-conducting oil is filled in the interlayer of the double-layer structure to absorb the heat generated during the reaction process through the heat-conducting oil. Therefore, the accumulation of carbon black on the inner wall of the reactor will also affect heat exchange, and further affect the silicone yield. Therefore, when the carbon black product hinders the heat absorption efficiency of the reactor wall and the heat exchange tube wall after about 40 days of operation of the device, it is necessary to stop the operation for cleaning, which hinders the continuous production and reduces the production efficiency. Summary of the Invention

[0004] The present invention aims to provide a silicone synthesis system and method that uses dynamic steel ball flow heat exchange and self-cleaning to solve the technical problem that in the current silicone synthesis system, a specific heat exchange mechanism needs to be arranged in the reactor and the reactor needs to be cleaned regularly.

[0005] To solve the above technical problems, the specific solution adopted by the present invention is: a silicone synthesis system that uses dynamic steel ball flow heat exchange and self-cleaning, including a reactor for synthesizing silicone. A rolling cleaning area is arranged on the inner wall of the reactor, and a plurality of sliding channels for steel balls to slide are arranged to cover the rolling cleaning area. A ball feeding device capable of feeding steel balls into the sliding channels is arranged at the top of the reactor, and a ball discharging device for discharging steel balls from the reactor is arranged at the bottom of the reactor.

[0006] As a further optimization of the above technical solution: the sliding channels are spirally distributed along the inner wall of the reactor.

[0007] As a further optimization of the above technical solution: The goal-scoring device includes a first ball-transporting pipe and a second ball-transporting pipe that are connected in sequence from top to bottom. The first ball-transporting pipe is fixedly installed above the reactor. The second ball-transporting pipe includes a vertical section and an inclined section. The vertical section penetrates through the upper head of the reactor and is rotatably connected to the upper head. The upper end of the vertical section is rotatably connected to the first ball-transporting pipe, and the lower end is fixedly connected to the inclined section located inside the reactor. The ball outlet of the inclined section faces the upper part of the rolling cleaning area on the inner wall of the reactor. A power mechanism for driving the second ball-transporting pipe to rotate is provided outside the reactor.

[0008] As a further optimization of the above technical solution: The power mechanism is a driving motor. Sprockets are sleeved on the outside of the vertical section and the output shaft of the driving motor, and the two sprockets are connected by a chain drive.

[0009] As a further optimization of the above technical solution: The ball-discharging device includes a ball-discharging bin and a ball-discharging pipe for discharging steel balls from the ball-discharging bin. A ball-discharging channel is opened on the lower head of the reactor, and the ball inlet of the ball-discharging bin is communicated with the ball-discharging channel.

[0010] As a further optimization of the above technical solution: The ball-discharging pipe is inclined, and its ball inlet end is higher than the ball outlet end; a ball-guiding plate is inclined in the ball-discharging bin. The ball outlet of the ball-discharging bin is opened on the side wall of the ball-discharging bin and is located at the ball outlet end of the ball-guiding plate. The lower edge of the ball outlet of the ball-discharging bin is flush with the upper edge of the ball-guiding plate.

[0011] As a further optimization of the above technical solution: The ball-guiding plate is a hollow plate.

[0012] As a further optimization of the above technical solution: A lifting device for transporting the steel balls discharged by the ball-discharging device to the goal-scoring device is provided outside the reactor.

[0013] As a further optimization of the above technical solution: The lifting device includes a vertical lifting pipe, a vertical lifting mechanism arranged in the lifting pipe, a ball-transporting trolley, and a transport guide rail. The transport guide rail includes a first transport guide rail and a second transport guide rail that are vertically arranged and spaced apart. The upper end of the second transport guide rail has a bent section extending to the goal-scoring device; the ball-transporting trolley includes an open carriage and a ball-unloading plate arranged on one side of the carriage. The ball-unloading plate is higher than the upper edge of the carriage. A first rotating shaft is arranged at the bottom of the carriage, and a second rotating shaft is arranged at the upper end of the ball-unloading plate. The first rotating shaft is located in the second transport guide rail, and the second rotating shaft is located in the second transport guide rail; the ball-transporting trolley is connected to the vertical lifting mechanism and can move up and down with the vertical lifting mechanism. When the ball-transporting trolley moves to the upper part of the lifting pipe, the second rotating shaft enters the bent section of the second transport guide rail, so that the steel balls in the ball-transporting trolley can enter the goal-scoring device along the inclined ball-unloading plate.

[0014] A heat exchange and self-cleaning method for a silicone synthesis system, which conveys steel balls into the slideways on the inner wall of the silicone synthesis reactor, and uses the sliding of the steel balls in the reactor to absorb the heat released by the silicone synthesis reaction and remove the carbon black adhering to the inner wall of the reactor.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By arranging multiple slideways for the steel balls to slide on the inner wall of the reactor in the present invention, during the use process, the steel balls are sent into the slideways by the ball feeding device, and multiple steel balls are arranged in sequence and move downward (including sliding and rolling) in the slideways to form a dynamic steel ball flow. On the one hand, the steel balls absorb the heat released during the reaction to cool the inner cavity of the reactor. On the other hand, the steel balls slide along the slideways, and by colliding and rubbing the inner wall of the reactor, the carbon black adhering to the inner wall of the reactor can be removed. The outer surface of the steel balls can also be directly attached to the carbon black generated during the reaction process, and the steel balls carry the carbon black out of the reactor to achieve self-cleaning treatment of the reactor.

[0017] By setting a dynamic steel ball flow, the cooling and carbon black cleaning operations in the reactor are carried out synchronously, eliminating the need to set up a specific heat exchange mechanism and the need to stop the machine to clean the carbon black. The steel balls forming the steel ball flow can be recycled, improving the production efficiency to a certain extent and reducing the production cost.

[0018] 2. A lifting device is arranged outside the reactor to convey the steel balls discharged by the ball discharging device into the ball feeding device to realize the recycling of the steel balls. The ball feeding device, the ball discharging device and the lifting device work together to realize the cyclic transmission of the steel balls, continuously cool and self-clean the reactor. The whole system has a high degree of automation and has good application prospects.

[0019] 3. The ball guiding plate in the ball discharging bin is set as a hollow plate. The carbon black cleaned by the steel ball flow in the reactor converges to the bottom of the reactor and is discharged through the hollow ball guiding plate after falling into the ball discharging bin, thus realizing the removal of carbon black in the reactor.

Detailed implementation manners

[0031] The technical solutions of the present invention will be further elaborated in detail below in combination with specific embodiments. For the parts that are not detailedly described and disclosed in the following embodiments of the present invention, they should all be understood as the prior art known or should be known to those skilled in the art, such as the material inlet and outlet of the reactor during the silicone synthesis reaction, the component structures related to the silicone synthesis reaction, etc.

[0032] Embodiment 1

[0033] As Figure 1As shown in the figure, the present invention discloses a silicone synthesis system that uses dynamic steel ball flow heat exchange and self-cleaning, including a reactor 1 for synthesizing silicone. The inner wall of the reactor 1 is provided with a rolling cleaning area and multiple sliding tracks 5 covering the rolling cleaning area for the steel balls to slide. At the top of the reactor 1, there is a ball feeding device 4 that can feed the steel balls into the sliding tracks 5, and at the bottom of the reactor 1, there is a ball discharging device 2 for discharging the steel balls from the reactor 1.

[0034] Specifically, the reactor 1 is cylindrical and includes a lower head 104, a conical section 103, a straight cylinder section 102, and an upper head 101 arranged in sequence from bottom to top. The rolling cleaning area includes the straight cylinder section 102 and the conical section 103. Figure 4 、 5 As shown in the figure, multiple sliding tracks 5 are distributed in parallel, and the width of each sliding track 5 is the same. The upper and lower ends of each sliding track 5 are open. The upper end of the sliding track 5 is flush with the upper end of the straight cylinder section 102, and the lower end is flush with the lower end of the conical section 103, so that the steel balls entering each sliding track 5 can slide from top to bottom and smoothly slide out from the lower end of the sliding track 5.

[0035] In order to extend the moving time and distance of the steel balls in the sliding tracks 5, the sliding tracks 5 are spirally distributed along the inner wall of the reactor 1. For the spirally arranged sliding tracks 5, the pitch can be adjusted according to the inner diameter and height of the reactor 1 to ensure that the steel balls can slide smoothly and avoid jamming.

[0036] As shown in Figure 2 、 4 the figure, the ball feeding device 4 includes a first ball conveying pipe 401 and a second ball conveying pipe 402 that are connected in sequence from top to bottom. The first ball conveying pipe 401 is fixedly installed above the reactor 1. There is a mounting frame (not shown in the figure) above the reactor 1, and the first ball conveying pipe 401 is fixed on the mounting frame. One end of the first ball conveying pipe 401 is open for feeding the steel balls into it, and the other end is connected to the second ball conveying pipe 402 to convey the steel balls to the second ball conveying pipe 402. The first ball conveying pipe 401 includes a cylindrical section and a necking section. The diameter of the cylindrical section is much larger than the diameter of the steel balls to provide a sufficient amount of steel balls. The diameter of the cylindrical section is 5 - 8 times the diameter of a single steel ball. The cylindrical section is inclined downward. The diameter of the necking section gradually decreases along the direction away from the cylindrical section. The opening at the end of the necking section faces downward, and the diameter at the end of the necking section is slightly larger than the diameter of the steel ball to ensure that a single steel ball can pass through smoothly.

[0037] The diameter of the second ball conveying pipeline 402 is the same as the end diameter of the necking section. The second ball conveying pipeline 402 includes a vertical section 4021 and an inclined section 4022. The vertical section 4021 is inserted through the upper end cap 101 of the reactor 1 and is concentrically distributed with the upper end cap 101. A rotating bearing 406 is provided at the connection between the vertical section 4021 and the upper end cap 101. The upper end of the vertical section 4021 is rotationally connected to the first ball conveying pipeline 401, and the lower end is fixedly connected to the inclined section 4022 located in the reactor 1. Specifically, the upper end of the vertical section 4021 is rotationally connected to the end of the diameter-reducing section of the first ball conveying pipeline 401. The rotational connection method adopts the existing technology. The lower end of the vertical section 4021 and the inclined section 4022 can be welded, integrally formed, or connected through a bend with a certain bending angle. The present invention provides a connecting bend between the inclined section 4022 and the vertical section 4021, and the connecting bend is welded and fixed to the vertical section 4021 and the inclined section 4022. A certain distance is left between the ball outlet of the inclined section 4022 and the inner wall of the reactor 1 , and the length of the inclined section 4022 is adjusted according to the inner diameter of the reactor 1 .

[0038] The ball outlet of the inclined section 4022 faces the upper part of the rolling cleaning zone of the inner wall of the reactor 1, and the axis of the ball outlet of the inclined section 4022 is inclined downward. The intersection of the axis with the side wall of the reactor 1 is located at the upper part of the rolling cleaning zone. The distance between the intersection of the axis with the side wall of the reactor 1 and the connection between the upper head 101 and the straight section 102 is less than 1 / 20 of the height of the straight section 102, which can enable the steel balls to form a steel ball flow of sufficient length in the slide 5 to prevent the steel balls from entering the slide 5 at a low initial position, thereby affecting the cooling and cleaning work of the reactor 1.

[0039] In order to avoid the blockage of steel balls in the necking section of the first ball conveying pipeline 401 and ensure the smooth transmission of steel balls, a feeder 6 is provided at the end of the necking section of the first ball conveying pipeline 401. The mechanism of the feeder 6 is the existing technology, including a feeding barrel 601 and a dividing mechanism arranged in the feeding barrel 601. The upper end of the feeding barrel 601 is fixedly connected to the end of the necking section by a flange, and the lower end is rotatably connected to the second ball conveying pipeline 402.

[0040] The reactor 1 is provided with a power mechanism for driving the second ball conveying pipeline 402 to rotate. The power mechanism is a driving motor 403, and a sprocket 405 is installed on the output shaft of the power mechanism and on the outside of the vertical section 4021. The two sprockets 405 are connected by a chain 404, and the driving motor 403 drives the second ball conveying pipeline 402 to rotate through the chain 404.

[0041] During the rotation of the second ball discharging pipeline 402, the steel balls inside it are thrown out due to centrifugal force, towards the inner wall of the reactor 1 and into the slideway 5, realizing the conveyance of the steel balls from the second ball discharging pipeline 402 to the slideway 5. There is a gap between the inclined section 4022 of the second ball discharging pipeline 402 and the inner wall of the reactor 1 to prevent the inclined section 4022 from touching the inner wall of the reactor 1 and affecting its rotation.

[0042] It should be noted that during the conveyance process, some steel balls may collide with the side wall of the slideway 5, causing the steel balls to deviate from the slideway 5 and resulting in the failure of conveyance. Since the second ball discharging pipeline 402 can continuously transfer steel balls to the inner wall of the reactor 1, the steel balls with conveyance failure can be ignored.

[0043] As Figure 3 、 5 shown, the ball discharging device 2 is located at the bottom of the reactor 1. The ball discharging device 2 includes a ball discharging bin 201 and a ball discharging pipeline 203 for discharging the steel balls from the ball discharging bin 201. The lower head 104 of the reactor 1 is provided with a ball discharging channel 1041. The ball discharging channel 1041 is concentrically distributed with the lower head 104. The ball discharging bin 201 is located directly below the lower head 104. The ball inlet of the ball discharging bin 201 is communicated with the ball discharging channel 1041 to convey the steel balls in the reactor 1 to the ball discharging bin 201.

[0044] The side wall of the ball discharging bin 201 is provided with a ball discharging port. A ball guiding plate 204 for guiding the discharge of the steel balls is inclined in the ball discharging bin 201. The ball discharging port is located at the lowest end of the ball guiding plate 204. The steel balls entering the ball discharging bin 201 move downward along the ball guiding plate 204 and flow out of the ball discharging port to the outside of the bin.

[0045] The ball guiding plate 204 includes two symmetrically arranged semi-circular plates. The straight edges of the two semi-circular plates are connected, and the included angle between the two semi-circular plates is an obtuse angle, forming a V-shaped sliding channel with an upward opening to guide the sliding of the steel balls. The lowest end of the V-shaped sliding channel is the lowest end of the ball guiding plate 204.

[0046] The ball guiding plate 204 is a hollow plate. On the one hand, the ball guiding plate 204 can guide the steel balls. On the other hand, the hollow holes on it can allow the carbon black to be discharged. The carbon black cleaned by the flow of the steel balls in the reactor 1 converges to the bottom of the reactor 1, falls into the ball discharging bin 201 through the ball discharging channel 1041, and is discharged from the hollow holes on the ball guiding plate 204. When the steel balls move to the ball guiding plate 204, part of the carbon black on the surface of the steel balls can also be discharged through the hollow plate during the movement.

[0047] A carbon black bin 202 is arranged directly below the ball discharging bin 201. The bottom of the ball discharging bin 201 is conical, and a discharge port is opened at the lowest part of the bottom. The discharge port of the ball discharging bin 201 is communicated with the feed port of the carbon black bin 202. The carbon black falling to the bottom of the ball discharging bin 201 converges at the conical bottom and flows towards the discharge port, and then falls into the carbon black bin 202.

[0048] The ball end of the ball outlet pipe 203 is connected to the ball outlet of the ball outlet bin 201. The ball outlet pipe 203 is tilted, and its ball end is higher than the ball outlet end to discharge the steel balls in the ball outlet bin 201. A control valve 205 is provided on the ball outlet pipe 203, and the steel balls are discharged at a fixed time by opening and closing the control valve 205.

[0049] The steel balls discharged from the ball outlet pipe 203 are cooled outside the reactor 1 and then sent to the feed port of the first ball delivery pipe 401 for recycling. The cooling of the steel balls can be achieved by natural cooling or by applying cold air.

[0050] Example 2

[0051] The overall structure of this embodiment is the same as that of embodiment 1, except that Figure 1 , 9 As shown, in this embodiment, a lifting device 3 is provided outside the reactor 1 for conveying the steel balls discharged from the ball outlet device 2 to the ball scoring device 4.

[0052] like Figure 6 , 7 As shown in Figure 8, the lifting device 3 includes a vertical lifting channel 302, a vertical lifting mechanism 303 arranged in the lifting channel 302, a ball transport trolley 305 and a conveying guide rail 304.

[0053] The vertical lifting mechanism 303 comprises a lower conveying wheel 3033 and an upper conveying wheel 3032, wherein the lower conveying wheel 3033 is located at the bottom of the lifting passage 302, and the upper conveying wheel 3032 is located at the top of the lifting passage 302. The upper conveying wheel 3032 and the lower conveying wheel 3033 are both connected with a conveying motor 301 for driving the rotation thereof, and the housing of the conveying motor 301 is fixed outside the lifting passage 302, and the output shaft extends into the lifting passage 302. The upper conveying wheel 3032 and the lower conveying wheel 3033 are connected by a conveyor belt body 3031. In the present embodiment, the upper conveying wheel 3032 and the lower conveying wheel 3033 are both pulleys, and the conveyor belt body 3031 is a conveying belt. In other embodiments of the present invention, the upper conveying wheel 3032 and the lower conveying wheel 3033 are set as sprocket wheels 405, and the conveyor belt body 3031 is a conveying chain 404. It is understandable that the vertical lifting mechanism 303 can also be a lifting structure of other prior art, which will not be described one by one.

[0054] The ball transporting trolley 305 is connected to the vertical lifting mechanism 303 and is driven by the vertical lifting mechanism 303 to move up and down.

[0055] like Figure 8As shown in the figure, the ball - transporting trolley 305 includes an open - topped carriage 3051 and a ball - discharging plate 3054 provided on one side of the carriage 3051. The carriage 3051 includes a bottom surface of the box body and four side walls of the box body. The bottom surface of the box body is rectangular. Three side walls of the box body are perpendicularly fixed to the bottom surface of the box body, and the fourth side wall is inclined and fixedly connected to the bottom surface of the box body. The included angle between the inclined side wall of the box body and the bottom surface of the box body is an obtuse angle, that is, the opening of the carriage 3051 is wider outside. The ball - discharging plate 3054 is fixedly connected to the inclined side wall of the box body and has the same inclination angle as the inclined side wall. The ball - discharging plate 3054 is higher than the upper edge of the carriage 3051. The ball - discharging plate 3054 and the inclined side wall of the box body can be connected by welding or integrally formed connection methods.

[0056] The ball - transporting trolley 305 is hinged to the conveyor belt body 3031, which is convenient for controlling the ball - transporting trolley 305 to flip after the trolley moves to the upper part of the lifting channel 302, so as to pour the steel balls in the carriage 3051 into the ball - transporting device.

[0057] The ball - transporting trolley 305 hinged to the conveyor belt body 3031 is likely to deflect inevitably during the up - and - down movement. In order to further ensure the stability of the ball - transporting trolley 305 during the up - and - down movement, a conveying guide rail 304 is provided in the lifting channel 302. The conveying guide rail 304 includes a first conveying guide rail 3041 and a second conveying guide rail 3042 that are vertically arranged and spaced apart. The upper end of the second conveying guide rail 3042 has a bent section extending to the ball - feeding device 4.

[0058] The ball - transporting trolley 305 is provided with a first rotating shaft 3052 and a second rotating shaft 3053. The first rotating shaft 3052 is located at the connection of the inclined side wall and the bottom of the carriage 3051 and is at the bottom of the box bottom. The second rotating shaft 3053 is located at the end of the ball - discharging plate 3054 away from the carriage 3051 and is at the bottom of the ball - discharging plate 3054. During use, the first rotating shaft 3052 is installed in the first conveying guide rail 3041, and the second rotating shaft 3053 is installed in the second conveying guide rail 3042. The first conveying guide rail 3041 limits the first rotating shaft 3052 to move up and down along the vertical track, avoiding shaking in the horizontal direction. Similarly, the second conveying guide rail 3042 limits the second rotating shaft 3053 to avoid its shaking in the horizontal direction, thereby ensuring the stability of the trolley during the lifting process. A limit block 3043 is also provided below the first conveying guide rail 3041 to limit the downward movement position of the ball - transporting trolley 305 and prevent its downward amplitude from being too low.

[0059] It can be understood that a first rotating shaft 3052 can also be arranged in the first conveying guide rail 3041, and a second rotating shaft 3053 can be arranged in the second conveying guide rail 3042. The connection between the inclined side wall and the bottom of the carriage 3051 in the ball conveying trolley 305 and the end of the ball discharging plate 3054 far from the carriage 3051 are respectively hinged to the first rotating shaft 3052 and the second rotating shaft 3053.

[0060] The hinge point of the ball conveying trolley 305 and the conveyor belt body 3031 is located at the connection between the ball discharging plate 3054 and the inclined side wall of the box body, that is, at the upper edge of the carriage 3051 and between the first rotating shaft 3052 and the second rotating shaft 3053. When the ball conveying trolley 305 moves to the upper part of the lifting channel 302, the conveyor belt body 3031 drives the ball conveying trolley 305 to continue to move upward. The second rotating shaft 3053 enters the bent section of the second conveying guide rail 3042, and the first rotating shaft 3052 continues to move upward. The height of the first rotating shaft 3052 is higher than that of the second rotating shaft 3053, and the carriage 3051 of the ball conveying trolley 305 inclines, and the steel balls in the ball conveying trolley 305 can enter the goal-scoring device 4 along the inclined downward ball discharging plate 3054.

[0061] In this embodiment, the feed inlet of the first ball conveying pipeline 401 of the goal-scoring device 4 is connected to the side wall of the lifting channel 302, and the inclined section 4022 of the second conveying guide rail 3042 extends into the first ball conveying pipeline 401, so that when the ball conveying trolley 305 inclines, the end of the ball discharging plate 3054 far from the ball conveying trolley 305 is located in the first ball conveying pipeline 401 and inclines downward to send the steel balls into the first ball conveying pipeline 401.

[0062] In order to improve the stability of the ball conveying trolley 305 during the moving process, the vertical lifting mechanism 303 is arranged in two groups and symmetrically arranged on both sides of the ball conveying trolley 305. Both sides of the ball conveying trolley 305 are hinged to the corresponding vertical lifting mechanism 303, and the hinge points on both sides are symmetrically distributed.

[0063] It should be noted that a goal-scoring port is also arranged on the side wall of the lifting channel 302 to send external steel balls into the ball conveying trolley 305 at the initial stage of the reaction.

[0064] The present invention also discloses a heat exchange and self-cleaning method for an organosilicon synthesis system, which conveys steel balls into the slideway 5 on the inner wall of the organosilicon synthesis reactor 1, and uses the steel balls to slide in the reactor 1 to absorb the heat released by the organosilicon synthesis reaction and remove the carbon black attached to the inner wall of the reactor 1.

[0065] Specifically, this method adopts the organosilicon synthesis system described in any one of Embodiment 1 or 2.

[0066] When the silicone synthesis system of Embodiment 1 is adopted: An external steel ball is placed into the first ball delivery pipeline 401 of the ball feeding device 4, and the driving motor 403 is started. The driving motor 403 drives the second ball delivery pipeline 402 to rotate at a high speed. During this process, the steel balls move downward along the first ball delivery pipeline 401 and gather at the necking section at its lower end. The steel balls are sent into the second ball delivery pipeline 402 by the feeder 6 connected to the end of the necking section. The steel balls that enter the second ball delivery pipeline 402 first move downward along the vertical section 4021, enter the inclined section 4022 located in the reactor 1. The steel balls that enter the inclined section 4022 rotate at a high speed along with the inclined section 4022. When moving to the opening of the inclined section 4022, the opening direction of the inclined section 4022 lacks the restraint on the steel balls, causing the steel balls to be thrown out under the action of centrifugal force, thrown towards the inner wall of the reactor 1 and enter the slideway 5, and move downward from top to bottom along the spiral slideway 5 (the moving mode includes sliding and rolling). Finally, they fall into the lower head 104 of the reactor 1 from the open end at the lower end of the slideway 5, enter the ball outlet bin 201 through the ball outlet channel 1041 opened on the lower head 104, and are then transported outside the reactor 1 by the ball delivery pipeline on one side of the ball outlet bin 201. At the same time, the carbon black cleaned by the steel ball flow gathers at the bottom of the reactor 1, falls into the ball outlet bin 201 through the ball outlet channel 1041, and is discharged from the hollowed-out holes on the ball guiding plate 204. Finally, after cooling and cleaning treatment, it is sent back into the first ball delivery pipeline 401 continuously.

[0067] When the silicone synthesis system of Embodiment 2 is adopted: The process of the steel balls entering the reactor 1, discharging from the reactor 1, and moving inside the reactor 1 is generally the same as that of the silicone synthesis system of Embodiment 1. The difference is that the steel balls discharged from the reactor 1 are sent into the ball feeding device 4 by the lifting device 3.

[0068] The steel balls are sent into the lifting channel 302 by the ball outlet pipeline 203 and loaded into the carriage 3051 of the ball delivery trolley 305. The conveying motor 301 is started, and the conveyor belt body 3031 drives the ball delivery trolley 305 to move upward. The ball delivery trolley 305 moves to the upper part of the lifting channel 302. The second rotating shaft 3053 of the ball delivery trolley 305 enters the bent section of the second conveying guide rail 3042, and the first rotating shaft 3052 continues to move upward. The height of the first rotating shaft 3052 is higher than that of the second rotating shaft 3053, the carriage 3051 of the ball delivery trolley 305 tilts, and the steel balls in the ball delivery trolley 305 enter the first ball delivery pipeline 401 along the inclined unloading plate 3054; the conveying motor 301 is started to rotate in the reverse direction, and the conveyor belt drives the ball delivery trolley 305 to move downward for the next steel ball lifting.

[0069] During the process of lifting the steel balls by the lifting channel 302, the steel balls can be naturally cooled, or a blower can be installed in the lifting channel 302 to cool the steel balls.
