Description

Technical Field

[0001] This utility model belongs to the field of industrial synthesis technology, specifically a special polyoxyethylene ether synthesis device. Background Technology

[0002] Polyoxyethylene ether, also known as polyethylene oxide or polyoxyethylene, is a crystalline, thermoplastic, water-soluble polymer. It is both a novel water-soluble resin and a nonionic surfactant. The demand for it is increasing across various industries, and from the perspective of the fields it has been developed in, the production and application prospects of polyoxyethylene ether are broad.

[0003] In existing technologies, the production of polyoxyethylene ethers typically requires synthesis, which involves processing with mechanical equipment. Synthesis equipment is commonly used and has a wide range of applications. The synthesis apparatus usually involves feeding the pulverized polyoxyethylene ether into a large stirring pipe. It typically consists of a frame, motor, gears, heating lamps, inlet, quartz tube, and outlet. The motor drives the stirring shaft to rotate, which in turn rotates the polyoxyethylene ether within the quartz tube. With the assistance of heating lamps, the polyoxyethylene ether within the quartz tube is processed, thus completing the synthesis of the polyoxyethylene ether.

[0004] In current technology, polyoxyethylene ether synthesis devices on the market typically operate using a motor mounted on the bottom. The motor drives a stirring shaft to rotate, which in turn rotates the polyoxyethylene ether inside a quartz tube. A heating lamp is used in conjunction to process the polyoxyethylene ether inside the quartz tube, thus completing the synthesis of polyoxyethylene ether. However, during the synthesis process, the polyoxyethylene ether usually needs to be preheated before being fed into the stirring furnace for synthesis. This production process is overly cumbersome, wastes the device's productivity, and results in low production efficiency. Therefore, to address these issues, a special polyoxyethylene ether synthesis device is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a special polyoxyethylene ether synthesis device includes a frame 7, an outer shell 3 mounted on the surface of the frame 7, an inner furnace shell 13 assembled inside the outer shell 3, furnace chamber end caps 27 mounted at both ends of the inner furnace shell 13, a lower furnace chamber 26 mounted on the inner wall of the furnace chamber end caps 27, a heating lamp tube 34 assembled inside the lower furnace chamber 26, the two ends of the heating lamp tube 34 connected to the furnace chamber end caps 27 via furnace chamber outer end caps 25, a decorative plate 30 mounted in the middle of the lower furnace chamber 26, the decorative plate 30 connected to the furnace chamber end caps 27 via side pressure plates 31, a quartz tube 33 assembled inside the heating lamp tube 34, a stirring shaft 32 mounted inside the quartz tube 33, a retaining ring 35 mounted on the circumferential surface of the quartz tube 33, an upper cover plate 4 mounted on the top of the outer shell 3, a hinge 5 assembled in the middle of the outer shell 3, and a rear cover plate 6 mounted on the side of the outer shell 3.

[0023] In current technology, polyoxyethylene ether synthesis devices typically operate using a motor 2 mounted on the bottom. The motor 2 drives a stirring shaft 32 to rotate, which in turn rotates the polyoxyethylene ether inside the quartz tube 33. A heating lamp 34 assists in processing the polyoxyethylene ether inside the quartz tube 33, thus completing the synthesis. However, during the synthesis process, the polyoxyethylene ether usually requires preheating before being fed into the feed pipe 12. This cumbersome process wastes resources and results in low efficiency. Therefore, to address these issues, a special polyoxyethylene ether synthesis device is proposed. During the synthesis operation, the output of the motor 2 mounted above the support frame 1 rotates, driving the stirring shaft 32 connected to its end to rotate. This, in turn, causes the polyoxyethylene ether inside the quartz tube 33 to rotate synchronously, completing the stirring and synthesis process.

[0024] Furthermore, a support frame 1 is mounted on one side of the frame 7, an adjusting plate 9 is fitted on the surface of the support frame 1, a sealing plate 10 is mounted on the surface of the adjusting plate 9, a front panel 19 is mounted on both sides of the sealing plate 10, a motor 2 is mounted on the other side of the front panel 19, a stuffing box cover 20 is mounted on the inner side of the front panel 19, a stuffing box bottom plate 24 is mounted on one side of the stuffing box cover 20, a stuffing box 23 is fitted on the surface of the stuffing box bottom plate 24, and a stuffing box 23 is mounted on the back of the stuffing box 23. The furnace is equipped with a feed pipe 12, the top of which is fitted with a concave flat welding plate 11. A fan mounting plate 18 is installed at the bottom of the inner furnace shell 13, and an electrical mounting plate 17 is installed below the fan mounting plate 18. A limit switch 16 is installed on one side of the decorative panel 30. A support plate 14 is installed on the side of the outer end cover 25 of the furnace chamber, and a water-cooled fixing ring 21 is installed on the back of the support plate 14. A feed support frame 22 is installed below the water-cooled fixing ring 21. A fuma wheel 8 is installed at the bottom of the frame 7. A discharge pipe 15 is fitted on the surface of the feed support frame 22, and a stirring shaft sleeve 28 is fitted onto the circumferential surface of the discharge pipe 15. A front cover 29 is installed on the other side of the stirring shaft sleeve 28, and a front cover sealing ring 36 is installed inside the front cover 29.

[0025] During operation, in the process of polyoxyethylene ether synthesis, polyoxyethylene ether usually needs to be preheated before being sent into the stirring furnace for synthesis. This production process is too cumbersome. By adding a ring of heating lamps 34 to the outside of the quartz tube 33, and installing a sealed lower furnace chamber 26 around the heating lamps 34 for heat preservation, the polyoxyethylene ether is fed into the quartz tube 33 through the feed pipe 12, and heating is carried out simultaneously. This improves the production efficiency of the equipment. When the polyoxyethylene ether is fed into the quartz tube 33 through the feed pipe 12, the stirring shaft 32 is rotated by the motor 2, and the external heating lamps 34 cooperate to continuously heat the polyoxyethylene ether in the quartz tube 33, thereby completing the overall polyoxyethylene ether synthesis process.

[0026] Working principle: In current technology, polyoxyethylene ether synthesis devices on the market typically operate using a motor 2 mounted on the bottom side. The motor 2 drives the stirring shaft 32 to rotate, thereby rotating the polyoxyethylene ether inside the quartz tube 33. This is coordinated with a heating lamp 34 to process the polyoxyethylene ether inside the quartz tube 33, thus completing the synthesis of polyoxyethylene ether. However, during the polyoxyethylene ether synthesis process, the polyoxyethylene ether usually needs to be preheated before being fed into the feed pipe 12 for synthesis. This production process is overly cumbersome, wastes the device's productivity, and has low production efficiency. Therefore, to address these issues, a special polyoxyethylene ether synthesis device is proposed. During the polyoxyethylene ether synthesis operation, the output end of the motor 2 mounted above the support frame 1 rotates, driving the stirring shaft 32 connected to the end to rotate, which in turn drives the polyoxyethylene ether inside the quartz tube 33 to rotate synchronously, completing the stirring synthesis operation. In the process of polyoxyethylene ether synthesis, polyoxyethylene ether usually needs to be preheated before being sent into a stirred furnace for synthesis. This production process is too cumbersome. By adding a ring of heating lamps 34 to the outside of the quartz tube 33, and installing a sealed lower furnace chamber 26 around the heating lamps 34 for heat preservation, the polyoxyethylene ether is fed into the quartz tube 33 through the feed pipe 12, and heating is carried out simultaneously. This improves the production efficiency of the equipment. When the polyoxyethylene ether is fed into the quartz tube 33 through the feed pipe 12, the stirring shaft 32 is rotated by the motor 2, and the external heating lamps 34 cooperate to continuously heat the polyoxyethylene ether in the quartz tube 33, thereby completing the overall polyoxyethylene ether synthesis process.
