Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to an outer disk semi-tube type heating stainless steel reactor. Background Art

[0002] Stainless steel reactor is a common chemical reaction equipment. The stainless steel inner reactor body is equipped with a stirring structure, which is composed of a motor, a reducer, a stirring shaft and a stirring paddle. The reactants are fully mixed by stirring to accelerate the reaction rate. A spiral outer disk half-tube is arranged on the outside of the reactor. Steam and other heat media are introduced into the half-tube. The heat medium flows in the half-tube and transfers heat to the reactor body, thereby heating the material in the reactor to achieve control of the reaction temperature.

[0003] In the prior art, a Chinese patent document with publication number CN113769680A discloses an outer disc semi-tube type heating stainless steel reactor, comprising a stainless steel reactor, a semi-circular outer coil is fixedly installed on the outer wall of the stainless steel reactor, a top feed pipe is provided on the top of the stainless steel reactor, a reduction box is fixedly installed inside the stainless steel reactor, a movable connecting shaft is fixedly installed on the top of the reduction box, a stirring motor is movably installed on the top of the movable connecting shaft, and a movable stirring blade is arranged. When the movable stirring blade is working, the movable stirring blade will swing left and right due to the action of centrifugal force, but the movable stirring blade is fixedly installed at the bottom of the movable stirring blade, and the movable spring has good elasticity, so the movable stirring blade will be pulled back to its original position by the movable spring during the swinging process, so as to avoid the movable stirring blade from shaking left and right during the working process, thereby extending the service life of the movable rod. However, this scheme still has the following shortcomings when actually used: In an outer disk half-tube type heated stainless steel reactor that uses steam as the heating medium, the current process often injects steam from the lower end of the semicircular outer coil and discharges it from the upper end. Since the steam is in a fast-flowing state, its residence time in the coil is short and it cannot completely fill the entire coil, resulting in limited contact area between the steam and the reactor wall and heat exchange time, making it difficult for the steam to fully transfer heat to the material in the reactor, resulting in low heat exchange efficiency. Not only does it cause the reactor to heat up slowly and the heating effect is poor, but the large amount of heat carried by the steam is not fully utilized, resulting in energy waste. Therefore, the present application provides an outer disk half-tube type heated stainless steel reactor to meet the needs of extending the retention time of steam in the semicircular outer coil to improve the heat exchange efficiency. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an outer coil semi-tube heating stainless steel reactor to solve the problem of low heat exchange efficiency caused by short residence time of steam in the coil.

The external coil pipe is spirally wound around the outer surface of the kettle body; Wherein, the release unit includes an air inlet pipe fixedly connected to the bottom end of the external coil pipe. The top end of the external coil pipe is fixedly connected with an exhaust pipe. A vertical rod is movably inserted through the upper surface of the air inlet pipe. A wind flow blade is fixedly sleeved on the outer surface of the vertical rod extending into the air inlet pipe; Wherein, a balance component is arranged on the outer surface of the exhaust pipe. A drainage component is arranged on the lower surface of the air inlet pipe. A diversion component is arranged inside the air inlet pipe.

[0006] Preferably, a central rod is movably inserted through the lower surface of the exhaust pipe. A plurality of fan plates are annularly arranged on the outer surface of the central rod extending into the exhaust pipe. The bottom end of the central rod is fixedly connected with a chassis.

[0007] Preferably, the top end of the vertical rod is fixedly connected with a dial block. A plurality of short rods are annularly arranged inside the chassis. The dial block is arranged in the gaps between the short rods. The number and distribution of the short rods are the same as those of the fan plates.

[0008] Preferably, the balance component includes a side pipe fixedly connected to the outer surface of the exhaust pipe. A piston is movably connected inside the side pipe. A push rod is fixedly connected to the center of the outer surface of the piston. The end of the push rod away from the piston is fixedly connected with a round plate, and the round plate is placed inside the exhaust pipe.

[0009] Preferably, the drainage component includes a drain pipe fixedly connected to the lower surface of the air inlet pipe. A semi-gear is fixedly sleeved on the outer surface of the bottom end of the vertical rod. A transmission rod is movably connected to the inner wall of the drain pipe. The top end of the transmission rod is fixedly connected with a first transmission wheel.

[0010] Preferably, a shaft rod is rotatably connected to the inner wall of the drain pipe. A baffle is fixedly connected to the outer surface of the shaft rod.

[0011] Preferably, the bottom end of the transmission rod is fixedly connected with a turntable. A vertical rod is rotatably connected to the edge of the lower surface of the turntable. A connecting rod is hinged to the outer surface of the vertical rod. A convex block is rotatably connected to the upper surface of the baffle. The end of the connecting rod away from the vertical rod is hinged to the convex block.

[0012] Preferably, the diversion component includes an inner rod rotatably connected to the inner wall of the air inlet pipe. A diversion plate is fixedly connected to the outer surface of the inner rod. A second transmission wheel is fixedly sleeved on the outer surface of the bottom end of the inner rod.

[0013] Preferably, a torsion spring is fixedly sleeved on the upper portion of the outer surface of the inner rod, and one end of the torsion spring away from the inner rod is fixedly connected to the inner wall of the intake pipe.

[0014] Preferably, the half gears are staggeredly meshed with transmission wheel one and transmission wheel two.

[0015] Beneficial effects of the present invention: 1. This type of outer disc semi-tube heating stainless steel reactor is equipped with a release unit. After the steam enters the air inlet pipe, it drives the air flow blades to rotate, driving the vertical rod to rotate eccentrically. The top shift block shifts the short rod, causing the center rod and the fan plates distributed in an annular shape on the outer surface to rotate intermittently. When the fan plates rotate, a gap is formed with the exhaust pipe to discharge steam. When they are stationary, the steam is blocked from flowing out, thereby extending the residence time of the steam in the outer coil and realizing indirect discharge of steam. The residence time of the steam in the outer coil is increased, thereby improving the heat exchange efficiency between the steam and the kettle body, making full use of the heat of the steam, and reducing heat loss.

[0016] 2. This type of outer coil semi-tube heating stainless steel reactor has a balancing component set on the side of the exhaust pipe. When the steam pressure in the outer coil increases, the steam is automatically discharged into the side pipe to push the piston to slide, thereby achieving rapid pressure relief. The fan plate rotates and moves the disc to discharge the steam accumulated in the side pipe. The dynamic balancing method can be used to control the pressure fluctuation in the outer coil within a very small range, thereby avoiding equipment damage or safety hazards caused by excessive pressure.

[0017] 3. This type of outer disk semi-tube heating stainless steel reactor is equipped with a drainage component and the lower surface of the air inlet pipe. After the condensed water flows into the air inlet pipe along the outer coil, it accumulates on the baffle of the drain pipe. The vertical rod rotates to drive the semi-gear transmission, which drives the turntable, vertical rod and connecting rod to move by engaging with the transmission wheel, so that the baffle reciprocates around the shaft rod. When the baffle is horizontal, it blocks the drain pipe to prevent steam from being discharged. When the baffle is tilted, the condensed water flows into the drain pipe and is discharged, effectively avoiding the water hammer phenomenon caused by the reflux of condensed water and the encounter of steam.

[0018] 4. This type of outer disk half-tube heating stainless steel reactor, by setting a guide component, drives the inner rod to rotate through the engagement of the half gear and the transmission wheel 2, so that the guide plate is deflected, and the rotation is achieved by the torsion spring, so as to achieve the dynamic guide effect of the guide plate, effectively eliminate the eddy current and turbulence at the bend of the intake pipe and the outer coil, improve the steam flow pattern, and improve the steam transportation efficiency in the outer coil.

[0024] Such asFigures 1 to 7 As shown, an outer disc semi-tube heating stainless steel reactor comprises a shell unit and a release unit The shell unit includes a kettle body 11, a top cover 12, a stirring mechanism 13 and an outer coil 14, wherein the top cover 12 is arranged at the top end of the kettle body 11, the stirring mechanism 13 is arranged on the upper surface of the top cover 12 and extends into the kettle body 11, the outer coil 14 is spirally wound on the outer surface of the kettle body 11, the release unit includes an air intake pipe 21 fixedly connected to the bottom end of the outer coil 14, an exhaust pipe 22 is fixedly connected to the top end of the outer coil 14, a balancing component is arranged on the outer surface of the exhaust pipe 22, a drainage component is arranged on the lower surface of the air intake pipe 21, and a flow guide component is arranged inside the air intake pipe 21; During the processing of materials, the materials are transported to the interior of the kettle body 11 through structures such as a feed pipe, and the stirring mechanism 13 is operated to stir the materials in the kettle body 11 to facilitate the reaction between the materials. At the same time, the steam is transported from the air inlet pipe 21 to the outer coil 14, and the high temperature of the steam is used to heat the materials, thereby promoting the rapid reaction. The release unit can realize indirect discharge of steam, improve the heat exchange efficiency between the steam and the kettle body 11, and make full use of the heat of the steam. At the same time, the balancing component on the side of the exhaust pipe 22 can balance the pressure of the steam flow, maintain the pressure balance in the outer coil 14, and use the drainage component to discharge the condensed water. The guide component can guide the steam to avoid the formation of vortices or turbulence at the bend where the air inlet pipe 21 and the outer coil 14 are connected, thereby improving the steam transportation efficiency in the outer coil 14.

[0025] like Figure 2 , Figure 3 and Figure 5 As shown, a vertical rod 23 is movably inserted into the upper surface of the air inlet pipe 21, and the vertical rod 23 extends into the outer surface of the air inlet pipe 21 and is fixedly sleeved with a wind blade 24. A central rod 25 is movably inserted into the lower surface of the exhaust pipe 22, and the central rod 25 extends into the outer surface of the exhaust pipe 22 and is distributed with fan plates 26 in a circular array. The bottom end of the central rod 25 is fixedly connected to a chassis 27, and the top end of the vertical rod 23 is fixedly connected to a shift block 28. Short rods 29 are distributed in a circular array inside the chassis 27. The shift block 28 is set in the gap of the short rods 29. The number and distribution of the short rods 29 are the same as those of the fan plates 26. Steam is transported into the air inlet pipe 21 to drive the air flow blades 24 to rotate, which in turn drives the vertical rod 23 to rotate. During the rotation of the vertical rod 23, the shifting block 28 on the top thereof will indirectly shift the short rod 29, thereby driving the chassis 27 and the center rod 25 to rotate indirectly. The angle of each rotation of the center rod 25 is fixed. The fan plate 26 rotates with the center rod 25, which will cause a gap between the fan plate 26 and the exhaust pipe 22. Part of the steam can be discharged with each rotation, thereby realizing indirect discharge of the steam, which increases the time that the steam stays inside the outer coil 14, thereby improving the heat exchange efficiency between the steam and the kettle body 11, making full use of the heat of the steam, and reducing heat loss.

[0026] like Figure 3 and Figure 4 As shown, the balancing assembly includes a side pipe 31 fixedly connected to the outer surface of the exhaust pipe 22, a piston 32 is movably connected inside the side pipe 31, a push rod 33 is fixedly connected to the center of the outer surface of the piston 32, and a disc 34 is fixedly connected to the end of the push rod 33 away from the piston 32, and the disc 34 is placed inside the exhaust pipe 22; When the pressure of the steam accumulated in the outer coil 14 increases, it will be discharged into the side pipe 31, which will push the piston 32 to slide inwardly of the side pipe 31, thereby releasing the pressure of the steam in the outer coil 14 and maintaining the pressure balance in the outer coil 14. During each rotation of the fan plate 26, the disc 34 will be moved, thereby pulling the piston 32 to slide in the direction of the exhaust pipe 22 through the push rod 33, thereby discharging the steam in the side pipe 31 and balancing the pressure next time.

[0027] like Figure 2 , Figure 6 and Figure 7 As shown, the drainage assembly includes a drain pipe 41 fixedly connected to the lower surface of the air inlet pipe 21, a half gear 42 is fixedly sleeved on the outer surface of the bottom end of the vertical rod 23, a transmission rod 43 is movably connected to the inner wall of the drain pipe 41, a transmission wheel 44 is fixedly connected to the top of the transmission rod 43, an axle rod 45 is rotatably connected to the inner wall of the drain pipe 41, a baffle plate 46 is fixedly connected to the outer surface of the axle rod 45, a turntable 47 is fixedly connected to the bottom end of the transmission rod 43, a vertical rod 48 is rotatably connected to the edge of the lower surface of the turntable 47, a connecting rod 49 is hinged on the outer surface of the vertical rod 48, a convex block 410 is rotatably connected to the upper surface of the baffle plate 46, and an end of the connecting rod 49 away from the vertical rod 48 is hinged to the convex block 410; The liquefied condensate flows downward along the outer coil 14 until it flows into the upper surface of the baffle 46 in the drain pipe 41 and temporarily accumulates. The baffle 46 can prevent the steam from flowing into the drain pipe 41. The rotation of the vertical rod 23 will drive the half gear 42 to rotate. When the half gear 42 is engaged with the transmission wheel 44, it will drive the transmission wheel 44 to rotate 180 degrees. After being driven by the transmission rod 43, it will drive the turntable 47 to rotate. The vertical rod 48 will rotate with the turntable 47 and drive the connecting rod 49 to move. The connecting rod 49 swings in an arc and pulls or pushes the baffle 46 to reciprocate around the shaft 45 through the protrusion 410. During the deflection of the baffle 46, the condensate will flow downward along the inclined baffle 46 into the drain pipe 41, thereby achieving the purpose of discharging the condensate, avoiding the reflux of the condensate and the high-speed flowing steam, which will cause water hammer, and ensuring the stability of the pipeline.

[0028] like Figure 2 and Figure 6As shown, the air guide assembly includes an inner rod 51 rotatably connected to the inner wall of the air intake pipe 21, a guide plate 52 is fixedly connected to the outer surface of the inner rod 51, a transmission wheel 2 53 is fixedly sleeved on the outer surface of the bottom end of the inner rod 51, a torsion spring 54 is fixedly sleeved on the upper outer surface of the inner rod 51, and one end of the torsion spring 54 away from the inner rod 51 is fixedly connected to the inner wall of the air intake pipe 21, and the half gear 42 is staggeredly meshed with the transmission wheel 1 44 and the transmission wheel 2 53; When the half gear 42 is meshed with the transmission wheel 2 53, it will drive the transmission wheel 2 53 to rotate 180 degrees. The transmission wheel 2 53 drives the inner rod 51 to rotate synchronously, and the guide plate 52 deflects accordingly. The rotation of the inner rod 51 will squeeze the torsion spring 54. After the half gear 42 is separated from the transmission wheel 2 53, the rebound of the torsion spring 54 will drive the inner rod 51 and the guide plate 52 to rotate. The back and forth swinging of the guide plate 52 can dynamically guide the steam to prevent the steam from forming eddy currents or turbulence at the bending point where the air inlet pipe 21 is connected to the outer coil 14, making the steam flow more stable and orderly, thereby improving the steam transportation efficiency in the outer coil 14.

[0029] According to the technical solution provided by the present invention, during the material processing, the material is transported to the interior of the kettle body 11 through a feeding pipe and other structures, and the stirring mechanism 13 is operated to stir the material in the kettle body 11 to facilitate the reaction between the materials. At the same time, steam is transported from the air inlet pipe 21 to the outer coil 14, and the high temperature of the steam is used to heat the material to promote the rapid reaction. The steam transported into the air inlet pipe 21 will drive the wind flow blades 24 to rotate, and the driving force of the steam transport is used as the power to drive the vertical rod 23 to rotate as a transmission structure. Since the vertical rod 23 is set at an eccentric position of the chassis 27, the shifting block 28 on the top of the vertical rod 23 will indirectly shift the short rod 29 during the rotation of the vertical rod 23, driving the chassis 27 and the center rod 25 to rotate indirectly. The angle of each rotation of the center rod 25 is fixed. Since the fan plates 26 on the outer surface of the center rod 25 are distributed in an annular shape, the discharge of steam can be blocked, and the fan plates 26 will cause the rotation of the center rod 25. There is a gap between the fan plate 26 and the exhaust pipe 22, and part of the steam can be discharged with each rotation, thereby realizing indirect discharge of the steam, which increases the time the steam stays inside the outer coil 14, improves the heat exchange efficiency between the steam and the kettle body 11, makes full use of the heat of the steam, and reduces heat loss. In addition, a side pipe 31 is provided on the side of the exhaust pipe 22. When the pressure of the steam accumulated in the outer coil 14 increases, it will be discharged into the side pipe 31, which will push the piston 32 to slide inside the side pipe 31, thereby realizing the pressure relief of the steam in the outer coil 14 and maintaining the pressure balance in the outer coil 14. During each rotation of the fan plate 26, the disc 34 will be moved, thereby pulling the piston 32 to slide in the direction of the exhaust pipe 22 through the push rod 33, thereby achieving the purpose of discharging the steam in the side pipe 31, which is convenient for the next pressure balance. The dynamic balance method can be used to control the pressure fluctuation in the outer coil 14 within a very small range, thereby avoiding equipment damage or safety hazards caused by excessive pressure. As the steam flows in the outer coil 14 and exchanges heat with the kettle body 11, the temperature decreases and liquefaction inevitably occurs. The liquefied condensed water flows downward along the outer coil 14 until it flows into the intake pipe 21. Since the lower surface of the intake pipe 21 is connected to the drain pipe 41, the condensed water will flow into the upper surface of the baffle 46 in the drain pipe 41 and accumulate temporarily. The baffle 46 can block the steam from flowing into the drain pipe 41. During the rotation of the vertical rod 23, the semi-gear 42 will be driven to rotate. The semi-gear 42 will indirectly engage the first transmission wheel 44 and the second transmission wheel 53. When engaging with the first transmission wheel 44, it will drive the first transmission wheel 44 to rotate 180 degrees. After being transmitted by the transmission rod 43, the turntable 47 will be driven to rotate. The vertical rod 48 will rotate with the turntable 47 and drive the connecting rod 49 to move. The connecting rod 49 swings in an arc and pulls or pushes the baffle 46 to rotate reciprocally around the shaft rod 45 through the convex block 410. During the deflection of the baffle 46, the condensed water will flow downward along the inclined baffle 46 and enter the drain pipe 41, achieving the purpose of discharging the condensed water, avoiding the condensed water from flowing back and meeting the high-speed flowing steam, which will cause water hammer phenomenon and ensuring the stability of the pipeline. In addition, when the semi-gear 42 engages with the second transmission wheel 53, it will drive the second transmission wheel 53 to rotate 180 degrees. The second transmission wheel 53 drives the inner rod 51 and the synchronous plate to rotate, and the guide plate 52 deflects accordingly. The rotation of the inner rod 51 will compress the torsion spring 54. After the semi-gear 42 is separated from the second transmission wheel 53, the torsion spring 54 will rebound and drive the inner rod 51 and the guide plate 52 to rotate back. The back-and-forth swing of the guide plate 52 can dynamically guide the steam, avoiding the formation of eddy currents or turbulent flows at the bending part where the intake pipe 21 is connected to the outer coil 14, making the steam flow more stable and orderly, and thus improving the conveying efficiency of the steam in the outer coil 14.
