Description

Technical Field

[0001] This utility model relates to the field of water vapor removal technology for resin reactors, and in particular to a water vapor removal device for resin reactors. Background Technology

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. Broadly speaking, any polymer compound that can be used as a raw material for plastic products is called a resin. In the resin production process, it is necessary to remove the water vapor generated in the reaction vessel. Existing reaction vessels all use nitrogen generators to purge nitrogen into the vessel to remove the water vapor, which is costly and not very effective at removing water vapor.

[0003] In related technologies, such as Chinese patent application number "CN202023095698.X", entitled "A Water Vapor Removal Device for a Resin Reactor", it includes a support frame, an outer casing fixedly installed inside the support frame, a reactor fixedly connected inside the outer casing, water separators fixedly installed on both sides of the reactor, a support rod and a support plate fixedly connected to the inner wall of the water separator, the support plate located on one side of the support rod, and a water absorber installed in the middle of the support plate. A grid plate and a support rod are fixedly connected to the inner wall of the water absorber. This utility model device, through the cooperation of a motor and fan blades inside the water separator, can discharge water vapor from inside the reactor, thus being relatively simple and efficient. The water absorbent cotton inside the water absorber can adsorb water vapor, preventing it from flowing back into the reactor, thereby removing water vapor more efficiently. When the water absorbent cotton is saturated, a cylinder drives the grid plate to squeeze out the water inside the absorbent cotton, allowing the absorbent cotton to continue adsorbing, thus reducing costs.

[0004] While the aforementioned patent can remove water vapor cost-effectively, it requires dual-motor power drive, which is not energy-efficient. Furthermore, the motors are located near the reactor, and the high temperature and water vapor generated during reactor operation can damage the motors and reduce their lifespan. Utility Model Content

[0006] To achieve the above objectives, a water vapor removal device for a resin reactor is provided, comprising an outer casing, a support fixedly connected to the outer side wall of the outer casing, a reactor fixedly connected inside the outer casing, a water storage chamber provided between the reactor and the outer casing, a feed inlet provided through the outer casing at the top of the reactor, water vapor removal mechanisms symmetrically provided on the left and right side walls of the reactor, and a bidirectional drive device for driving the water vapor removal mechanisms is provided on the outer side of the outer casing.

[0007] According to the aforementioned water vapor removal device for a resin reactor, the water vapor removal mechanism includes a conduit that is connected through the side wall of the reactor. A support frame one and a support frame two are fixedly connected to the inner side wall of the conduit. A rotating shaft one is rotatably connected through the middle of the support frame one and the support frame two via a bearing. A fan blade is fixedly connected to the end of the rotating shaft one facing the reactor. Water-absorbing cotton for absorbing water vapor is placed inside the conduit, and a squeezing component for squeezing the water-absorbing cotton is provided at the outer end of the conduit.

[0008] According to the aforementioned desiccant device for a resin reactor, the extrusion assembly includes a connecting plate fixedly connected to the outer end of a conduit, a cylinder fixedly connected to the bottom end of the connecting plate, a grid plate fixedly connected to the movable end of the cylinder, and the grid plate located inside the conduit.

[0009] According to the aforementioned water vapor removal device for a resin reactor, an exhaust port is provided at the top of the conduit, and the exhaust port is located between support frame one and support frame two.

[0010] According to the aforementioned desiccant device for a resin reactor, the bottom end of the conduit is connected to a collecting hopper, the collecting hopper being positioned opposite to the absorbent cotton, and the bottom end of the collecting hopper being connected to the side wall of the water storage chamber.

[0011] According to the aforementioned water vapor removal device for a resin reactor, the bidirectional drive device includes a mounting frame fixedly connected to the side wall of the outer casing. A dual-shaft motor is fixedly mounted on the mounting frame. Two rotating shafts are fixedly connected to both output ends of the dual-shaft motor. The other end of each rotating shaft passes through the side wall of the mounting frame and is fixedly connected to a transmission wheel. The side wall of the transmission wheel is connected to the transmission wheel 2 via a belt drive.

[0012] According to the aforementioned water vapor removal device for a resin reactor, the inner sidewalls of the two transmission wheels are fixedly connected to the sidewalls of the rotating shafts on both sides.

[0013] According to the aforementioned water vapor removal device for a resin reactor, a drain pipe is fixedly connected to the bottom end of the water storage chamber through the outer casing, and a water valve is installed inside the drain pipe.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, by setting up a water vapor removal mechanism and a bidirectional drive device, when removing water vapor from the reactor, the bidirectional drive device drives the rotating shafts on both sides to rotate synchronously, driving the fan blades to rotate and draw the water vapor outward. Before the water vapor is discharged to the outside, its moisture is absorbed by the absorbent cotton, preventing the water vapor from flowing back into the reactor. The cylinder pushes the grid plate to cooperate with the support frame to squeeze the moisture in the absorbent cotton. The squeezed water enters the water storage chamber through the collection hopper, which helps to cool the reactor. It can be reused repeatedly, and the overall operating cost of the device is lower. The dual-shaft motor is installed on the outside, which makes it easier to dissipate heat and improves its service life.

[0016] 2. Compared with the existing technology, by setting an exhaust port between two support frames, the moisture in the water vapor is absorbed by the water-absorbing cotton, and the steam is discharged through the exhaust port. Combined with the fan blades, the airflow between the reactor and the outside is smoother, thus improving the steam emission efficiency. Attached Figure Description

[0026] The water vapor removal mechanism 4 includes a conduit 401 that is connected to the side wall of the reactor 8. A support frame 1 403 and a support frame 2 404 are fixedly connected to the inner side wall of the conduit 401. A rotating shaft 1 406 is rotatably connected through the middle of the support frame 1 403 and the support frame 2 404 via a bearing. A fan blade 405 is fixedly connected to the end of the rotating shaft 1 406 facing the reactor 8. Water-absorbing cotton 407 that absorbs water vapor is placed inside the conduit 401. A squeezing assembly for squeezing the water-absorbing cotton 407 is provided at the outer end of the conduit 401. An exhaust port 4011 is opened at the top of the conduit 401 and is located between the support frame 1 403 and the support frame 2 404. A collection hopper 402 is connected to the bottom end of the conduit 401. The position of the collection hopper 402 corresponds to that of the water-absorbing cotton 407. The bottom end of the collection hopper 402 is connected to the side wall of the water storage chamber 9.

[0027] The extrusion assembly includes a connecting plate 409 fixedly connected to the outer end of the conduit 401, a cylinder 410 fixedly connected to the bottom end of the connecting plate 409, a grid plate 408 fixedly connected to the movable end of the cylinder 410, and the grid plate 408 located inside the conduit 401.

[0028] The bidirectional drive device 5 includes a mounting bracket 501 fixedly connected to the side wall of the outer casing 1. A dual-axis motor 502 is fixedly mounted on the mounting bracket 501. Two rotating shafts 503 are fixedly connected to both output ends of the dual-axis motor 502. The other end of each rotating shaft 503 passes through the side wall of the mounting bracket 501 and is fixedly connected to a transmission wheel 504.

The inner side walls of the two transmission wheels 505 are fixedly connected to the side walls of the rotating shafts 406 on both sides respectively. When removing water vapor from the reactor 8 using the desiccant mechanism 4 and the bidirectional drive device 5, the dual-shaft motor 502 is activated to drive the two rotating shafts 503 on both sides to rotate synchronously. Through the transmission wheels 504 and 505 and the belt 506, the two rotating shafts 406 on both sides rotate synchronously, causing the fan blades 405 to rotate and draw water vapor outwards. Before the water vapor is discharged to the outside, its moisture is absorbed by the absorbent cotton 407, preventing water vapor from flowing back into the reactor 8.

With the help of the fan blade 405, the air circulation between the reaction vessel 8 and the outside is smoother, which improves the steam emission efficiency.

[0029] Working principle: During use, when removing water vapor from the reactor 8, the dual-shaft motor 502 is started to drive the two rotating shafts 503 on both sides to rotate synchronously. Through the transmission wheel 504, the second rotating shaft 505 and the belt 506, the two rotating shafts 406 on both sides rotate synchronously, driving the fan blades 405 to rotate and draw the water vapor outward. The steam is discharged through the exhaust port 4011. The fan blades 405, together with the reactor 8, make the airflow between the reactor 8 and the outside more unobstructed. Before the water vapor is discharged to the outside, its moisture is absorbed by the absorbent cotton 407, preventing the water vapor from flowing back into the reactor 8. Next, the cylinder 410 is started to push the grid plate 408 and the support frame 404 to squeeze the moisture in the absorbent cotton 407. The squeezed water enters the water storage chamber 9 through the collection hopper 402 to help cool the reactor 8. It can be reused repeatedly, and the overall operating cost of the device is lower.
