[0014] Preferably, the vacuuming component includes a solenoid valve installed on the upper right side of the vessel body for opening the vacuuming end. A housing is installed on the right side of the solenoid valve. A cooling pipe, supplied with water by a spray device and used to cool the gas flowing through the housing, is spirally installed on the housing.

[0015] This invention provides a convenient-to-maintain reactor for processing ultra-high molecular weight polyethylene. Compared with the prior art, it has the following advantages:

[0016] (1) This easy-to-maintain ultra-high molecular weight polyethylene processing reactor, by setting agitators and sprayers in the device, allows the motor, bevel gear assembly, connecting shaft, connecting plate, and agitator to work together to agitate the raw materials and reduce the residue in the reactor by scraping, thereby improving the utilization rate of raw materials and reducing waste. After the ultra-high molecular weight polyethylene is prepared, the water pump, conduit, three-way valve, branch pipe, spray ring, sprayer, connecting shaft, and connecting plate work together to rinse and clean the inner wall of the reactor and the surface of the agitator, avoiding the difficulty of rinsing the agitator end due to obstruction, thus improving the cleaning efficiency of the inner wall of the reactor and the agitator end of the device.

[0017] (2) This easy-to-maintain ultra-high molecular weight polyethylene processing reactor has a vacuum pump installed inside the device. Before material processing, the vacuum pump evacuates the reactor through the casing, cooling pipe, and solenoid valve to reduce the impact of gas inside the reactor on subsequent processing and improve the preparation efficiency of the device. During the vacuuming process, the three-way valve is switched, and the water pumped by the water pump is introduced into the cooling pipe through the conduit, three-way valve, and connecting pipe. Then the water flows back to the water source through the return pipe outside the cooling pipe. After the gas inside the reactor comes into contact with the cooling pipe, the water flowing through the cooling pipe absorbs heat from the gas through heat exchange. The water vapor in the gas liquefies when it encounters cold air, which avoids the excessive temperature inside the reactor after the preparation of ultra-high molecular weight polyethylene, which could damage the vacuum pump. It also avoids the safety hazards caused by the direct discharge of high temperature steam. Attached Figure Description

[0023] 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 protection scope of the present utility model.

[0024] refer to Figure 1-4 This utility model provides the following two technical solutions:

[0025] First embodiment: A reactor for processing ultra-high molecular weight polyethylene (UHMWPE) that is easy to maintain, comprising a reactor body 1 with a feed inlet on the top right side, the reactor body 1 being connected to a processing component for UHMWPE processing, the processing component including: a feed valve 2, installed on the top right side of the reactor body 1 for adjusting the closed state of the feed inlet; a stirring component 3, installed on the reactor body 1 for stirring the raw materials and peeling off the raw materials adhering to the inner wall of the reactor body 1; a discharge valve 4, located at the bottom of the reactor body 1 for discharging the prepared materials from the reactor body 1; and a spray component 5, installed on the top of the reactor body 1 for rinsing and cleaning the inner wall of the reactor body 1 and the surface of the stirring end of the stirring component 3;

[0026] Vacuuming component 6 is installed on the right side of the vessel body 1 to reduce the influence of air on the preparation of ultra-high molecular weight polyethylene. Vacuuming component 6 is connected to spray component 5 to cool the extracted gas. Stirring component 3 includes a motor 31 installed on the top of the vessel body 1. A bevel gear assembly 32 is connected to the output end of the motor 31. A connecting shaft 33 driven by the bevel gear assembly 32 and connected to spray component 5 is rotatably connected to the top of the vessel body 1. Three sets of connecting plates 34 are installed on the side of the connecting shaft 33 near the inside of the vessel body 1. Stirring strips 35 that fit against the inner wall of the vessel body 1 are installed on the side of the connecting plates 34 away from the connecting shaft 33. A heating sleeve for heating is provided on the outside of the vessel body 1.

[0027] The bottom of the connecting plate 34 is provided with several first water spray holes for rinsing the stirring bar 35. A water channel for guiding water flow is vertically arranged inside the connecting shaft 33. The connecting plate 34 is hollow inside and communicates with the first water spray holes and the water channel respectively. The output end of the motor 31 is coaxially and fixedly connected to the driving bevel gear in the bevel gear assembly 32. The driven bevel gear in the bevel gear assembly 32 is coaxially and fixedly connected to the connecting shaft 33. The spray component 5 includes a water pump 51 for pumping water. The drain end of the water pump 51 is installed with... The vessel is equipped with a conduit 52, a three-way valve 53 for switching the water flow direction is installed at the front of the conduit 52, a connecting pipe 54 for supplying water to the cooling end of the vacuum pump 6 is installed at the rear of the three-way valve 53, a branch pipe 55 for supplying water to the agitator 3 is provided at the lower side of the three-way valve 53, a spray ring 56 for rinsing the inner wall of the vessel 1 is installed at the top edge of the vessel body 1, and a spray strip 57 for rinsing the agitator 3 is installed on the top left side of the vessel body 1, which is supplied with water by the branch pipe 55.

[0028] The water pump 51 is equipped with a water pump pipe at its pumping end. The bottom of the spray ring 56 is provided with several second spray holes, and the bottom of the spray strip 57 is provided with several third spray holes. The spray strip 57 is located inside the spray ring 56. The motor 31, bevel gear assembly 32, connecting shaft 33, connecting plate 34, and stirring strip 35 cooperate with each other to stir the raw materials and reduce the residual material in the reactor 1 by scraping. After the ultra-high molecular weight polyethylene is prepared, the water pump 51, conduit 52, three-way valve 53, branch pipe 55, spray ring 56, spray strip 57, connecting shaft 33, and connecting plate 34 cooperate with each other to rinse and clean the inner wall of the reactor 1 and the surface of the stirring strip 35.

[0029] The main difference between the second implementation method and the first implementation method is that:

[0030] The vacuuming component 6 includes a solenoid valve 63 installed on the upper right side of the vessel body 1 for opening the vacuuming end. A housing 62 is installed on the right side of the solenoid valve 63. A cooling pipe 64, supplied with water by the spray component 5 and used to cool the gas flowing through the housing 62, is spirally installed on the housing 62. The cooling pipe 64 is fixedly connected to and communicates with the connecting pipe 54. A vacuum pump 61 for vacuuming is installed on the right side of the housing 62. A drain valve 65 is installed at the middle of the bottom of the housing 62. A recovery pipe is provided at the bottom of the drain valve 65. A return pipe for cooling water is installed on the right side of the cooling pipe 64 near the outer end of the housing 62.

[0031] Before material processing, vacuum pump 61 evacuates the vessel 1 through casing 62, cooling pipe 64, and solenoid valve 63 to reduce the impact of gas in vessel 1 on subsequent processing. During the evacuation process, three-way valve 53 is switched, and water pumped by water pump 51 is introduced into cooling pipe 64 through conduit 52, three-way valve 53, and connecting pipe 54. Then, the water flows back to the water source through the return pipe on the outside of cooling pipe 64. After the gas in vessel 1 comes into contact with cooling pipe 64, the water flowing through cooling pipe 64 absorbs heat from the gas through heat exchange. Water vapor in the gas liquefies upon cooling, thus preventing high-temperature gas and steam in vessel 1 from damaging vacuum pump 61.

[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0033] During use, the user sets up a recovery component at the bottom of the discharge valve 4, opens the feed valve 2, and introduces the raw material for preparing ultra-high molecular weight polyethylene into the reactor body 1. The material remains on the upper side of the discharge valve 4. After the feeding is completed, the feed valve 2 is closed, and the reactor body 1 is evacuated by the vacuuming component 6 to reduce the impact of the air trapped in the reactor body 1 on the preparation of ultra-high molecular weight polyethylene. After the evacuation of the reactor body 1 is completed, power is supplied to the heating sleeve on the side of the reactor body 1 so that the heating sleeve supplies heat to the reactor body 1. At the same time, the motor 31 drives the connecting shaft 33, the connecting plate 34, and the stirring bar 35 to rotate through the bevel gear assembly 32. The rotating stirring bar 35 stirs the material and scrapes the inner wall of the reactor body 1 to reduce material adhesion and achieve mixing, heating and stirring of the mixture. After the material is processed, the discharge valve 4 is opened, and the material falls into the recovery component under the action of gravity.

[0034] Then, the discharge valve 4 is closed, and the water pump 51 is started. The water pump 51 draws external water through the water pipe, and then the water is supplied to the connecting shaft 33, the spray ring 56, and the spray bar 57 through the conduit 52, the three-way valve 53, and the branch pipe 55 respectively. The water injected into the connecting shaft 33 is sprayed out from the water channel and several first spray holes at the bottom of the connecting plate 34. The water sprayed from the bottom of the connecting plate 34 washes the end of the stirring bar 35 that is blocked by the connecting plate 34. Several second spray holes at the bottom of the spray ring 56 wash the inner wall of the vessel body 1. Several third spray holes at the bottom of the spray bar 57 wash the top and sides of the connecting plate 34 and the sides of the stirring bar 35, promoting the washing of the inner wall of the vessel body 1 and the side of the stirring bar 35. The processing residue attached to the stirring end of the stirring component 3 falls off, eliminating the need for frequent disassembly and cleaning of the vessel body 1, thus facilitating user maintenance. During the vacuuming process in the vacuum pump 61 within the vacuuming component 6, the vacuum pump 61 evacuates the vessel body 1 through the casing 62, cooling pipe 64, and solenoid valve 63. At this time, the three-way valve 53 is switched to start the water pump 51. The water pumped by the water pump 51 is introduced into the cooling pipe 64 through the connecting pipe 54. Then, the water flows back to the water source through the return pipe on the outside of the cooling pipe 64. After the gas in the vessel body 1 comes into contact with the cooling pipe 64, the water vapor in the gas liquefies upon cooling and remains in the receiving shell at the bottom of the casing 62. The drain valve 65 is opened periodically to discharge the cooling water through the recovery pipe, preventing water overflow.
