Description

Technical Field

[0001] The utility model relates to the technical field of polymer slurry stirring, in particular to a glass reaction kettle which can prevent high and low viscosity slurry discharge from being blocked. Background Art

[0002] The synthesis of polymers is usually completed through polymerization reactions, and a glass stirred reactor is an essential device for polymerization reactions. In a glass reactor, the monomer solution is heated and stirred to polymerize into a polymer slurry, which then flows into the collection equipment through the discharge port at the bottom of the reactor.

[0003] At present, the viscosity of commonly used polymer slurries is within 10000mPa.s, and the diameter of the discharge port of the general glass reactor is relatively small. When the synthetic viscosity is lower than 20000mPa.s for polymer slurry products, the discharge port can discharge the material smoothly; however, when the viscosity of the product is higher than 20000mPa.s, the discharge port is easily blocked and unable to discharge. Utility Model Content

[0004] In view of the above problems, a glass reactor is provided which can prevent the clogging of high and low viscosity slurry discharge. A threaded column is used to perform threaded lifting and lowering inside a large discharge pipe, thereby driving the sealing plug to move up and down. When the viscosity of the product slurry is lower than a specified value, the threaded column and the sealing plug are moved to the bottom of the small discharge pipe, and the slurry then flows out through the small discharge pipe. When the slurry viscosity is higher than a specified value, the threaded column and the sealing plug are screwed out of the large discharge pipe, and the high viscosity slurry then flows out directly from the large discharge pipe.

[0005] To solve the problems of the prior art, the utility model provides a glass reactor for preventing the discharge of high and low viscosity slurries from being blocked, comprising a support frame, a second mounting ring is arranged inside the support frame, an outer shell is arranged inside the second mounting ring, a reactor is arranged inside the outer shell, a cover plate is arranged on the top of the reactor, a large discharge pipe is connected to the bottom of the reactor, the large discharge pipe extends to the outside of the outer shell, a small discharge pipe is connected to the outer wall of the large discharge pipe, a threaded column is connected to the internal thread of the large discharge pipe, a sealing plug is arranged on the top of the threaded column, and a spring telescopic rod is arranged at the bottom of the support frame.

[0006] Preferably, a thermometer and a stirring motor are provided on the top of the cover plate, the detection end of the thermometer extends to the interior of the reactor, the output shaft of the stirring motor is provided with a stirring rod via a coupling, and the stirring rod extends to the interior of the reactor.

[0007] Preferably, the side walls of the support frame are respectively provided with a first mounting ring and a support plate, a condenser is provided inside the first mounting ring, and the bottom of the condenser is connected with the inside of the reactor through a pipeline.

[0008] Preferably, a water tank is arranged on the top of the support plate, a water pump is arranged inside the water tank, an input end of the water pump is connected with the inside of the water tank through a pipe, and an output end of the water pump is connected with the inside of the shell through a pipe.

[0009] Preferably, one side of the water storage tank is connected to a return pipe, one end of the return pipe is connected to the interior of the shell, and a first one-way valve and a second one-way valve are respectively provided inside the return pipe.

[0010] Preferably, a water outlet pipe is provided on the outer wall of the shell, one end of the water outlet pipe is connected with the inside of the return pipe, and a solenoid valve is provided inside the water outlet pipe.

[0011] Preferably, a heating rod is provided inside the water tank.

[0012] Preferably, a control cabinet is provided on the outer wall of the support frame.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The threaded column is used to lift and lower the thread inside the large discharge pipe, driving the sealing plug to move up and down. When the viscosity of the product slurry is lower than the specified value, the threaded column and the sealing plug are moved to the bottom of the small discharge pipe, and the slurry flows out through the small discharge pipe. When the slurry viscosity is higher than the specified value, the threaded column and the sealing plug are screwed out of the large discharge pipe, and the high-viscosity slurry flows directly from the large discharge pipe, effectively preventing the discharge port from being blocked.

[0015] 2. The hot water in the water tank is transferred to the inside of the outer shell by a water pump, which can heat the reactor and further accelerate the mixing reaction of the materials. At the same time, the water in the outer shell will flow into the water tank through the reflux pipe, so that water resources can be recycled. Two one-way valves are installed inside the reflux pipe to ensure that the hot water does not flow back. When the hot water is not needed after the stirring is completed, the solenoid valve is opened to allow the hot water inside the outer shell to flow into the water tank through the outlet pipe and the reflux pipe.

[0016] 3. The volatile materials are collected through the condenser, and the volatile materials can be re-liquefied on the condenser and refluxed into the reactor, avoiding the waste of materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 7 As shown, the utility model provides:

[0027] A glass reactor for preventing high and low viscosity slurry discharge from being blocked, comprising a support frame 1, a second mounting ring 16 is arranged inside the support frame 1, a shell 5 is arranged inside the second mounting ring 16, a reactor 4 is arranged inside the shell 5, a cover plate 3 is arranged on the top of the reactor 4, a large discharge pipe 12 is connected to the bottom of the reactor 4, the large discharge pipe 12 extends to the outside of the shell 5, a small discharge pipe 13 is connected to the outer wall of the large discharge pipe 12, a threaded column 14 is connected to the inner thread of the large discharge pipe 12, and a sealing plug 2 is arranged on the top of the threaded column 14. 3. A spring telescopic rod 11 is provided at the bottom of the support frame 1. The threaded column 14 is threadedly lifted and lowered inside the large discharge pipe 12 to drive the sealing plug 23 to move up and down. When the viscosity of the product slurry is lower than the specified value, the threaded column 14 and the sealing plug 23 are moved to the bottom of the small discharge pipe 13. At this time, the slurry flows out through the small discharge pipe 13. When the slurry viscosity is higher than the specified value, the threaded column 14 and the sealing plug 23 are screwed out from the large discharge pipe 12. At this time, the high-viscosity slurry flows directly from the large discharge pipe 12, effectively preventing the discharge port from being blocked.

[0028] Figure 5 As shown, a thermometer 21 and a stirring motor 20 are provided on the top of the cover plate 3 , the detection end of the thermometer 21 extends to the interior of the reactor 4 , and the output shaft of the stirring motor 20 is provided with a stirring rod 22 through a coupling, and the stirring rod 22 extends to the interior of the reactor 4 .

[0029] The progress of the experiment is judged by observing the display of the thermometer 21, and the material is fully stirred by using the stirring rod 22.

[0030] like Figure 1 and Figure 2 As shown, the side walls of the support frame 1 are respectively provided with a first mounting ring 7 and a support plate 10 , a condenser tube 6 is provided inside the first mounting ring 7 , and the bottom of the condenser tube 6 is connected to the inside of the reactor 4 through a pipeline.

[0031] The volatilized material is collected through the condenser 6 , and the volatilized material can be re-liquefied on the condenser 6 and refluxed into the reactor 4 , thus avoiding the waste of the material.

[0032] like Figure 3 As shown, a water tank 9 is arranged on the top of the support plate 10, and a water pump 8 is arranged inside the water tank 9. The input end of the water pump 8 is connected to the inside of the water tank 9 through a pipeline, and the output end of the water pump 8 is connected to the inside of the shell 5 through a pipeline.

[0033] The hot water in the water storage tank 9 is transferred to the inside of the housing 5 by the water pump 8, so as to heat the reactor 4 and further accelerate the mixing reaction of the materials.

[0034] like Figure 4As shown, one side of the water tank 9 is connected to a return pipe 15, one end of the return pipe 15 is connected to the interior of the housing 5, and a first one-way valve 19 and a second one-way valve 24 are respectively provided inside the return pipe 15.

[0035] The water flows into the water storage tank 9 through the return pipe 15 so that the water resources can be recycled. Two one-way valves are installed inside the return pipe 15 to ensure that the hot water does not flow back.

[0036] like Figure 4 As shown, a water outlet pipe 18 is disposed on the outer wall of the housing 5 , one end of the water outlet pipe 18 is connected to the inside of the return pipe 15 , and a solenoid valve 17 is disposed inside the water outlet pipe 18 .

[0037] The hot water in the housing 5 is finally flowed into the water storage tank 9 through the solenoid valve 17 via the water outlet pipe 18 and the return pipe 15, so as to be convenient for next use.

[0038] like Figure 3 As shown, a heating rod is arranged inside the water tank 9.

[0039] The water inside the water storage tank 9 can be continuously heated by the heating rod to accelerate the mixing reaction of the materials.

[0040] like Figure 1 As shown, a control cabinet 2 is provided on the outer wall of the supporting frame 1 .

[0041] The control cabinet 2 can facilitate the operation of the reactor 4 .

[0042] Working principle: first move the sealing plug 23 to the top of the small discharge pipe 13 to ensure that the slurry will not leak during operation, then add the material to be stirred from the feed port, start the stirring motor 20 to stir the material, and use the water pump 8 to transfer the hot water inside the water tank 9 to the inside of the outer shell 5 while stirring, so that the reactor 4 can be heated to further accelerate the mixing reaction of the materials. At the same time, the water inside the outer shell 5 will flow into the water tank 9 through the reflux pipe 15, so that water resources can be recycled. Two one-way valves are installed inside the reflux pipe 15 to ensure that hot water will not flow back. When hot water is not needed after stirring is completed, open the solenoid valve 17 to allow the hot water inside the outer shell 5 to finally flow into the water tank 9 through the outlet pipe 18 and the reflux pipe 15, which is convenient for next use. During the experiment, the progress of the experiment is judged by observing the display of the thermometer 21. At the same time, the condenser 6 can be used to collect the volatile materials. The volatile materials can be re-liquefied on the condenser 6 and refluxed into the reactor 4, avoiding waste of materials. After the stirring is completed, the threaded column 14 is used to perform threaded lifting and lowering inside the large discharge pipe 12, driving the sealing plug glue 23 to move up and down. When the viscosity of the product slurry is lower than the specified value, the threaded column 14 and the sealing plug glue 23 are moved to the bottom of the small discharge pipe 13. At this time, the slurry flows out through the small discharge pipe 13. When the slurry viscosity is higher than the specified value, the threaded column 14 and the sealing plug glue 23 are screwed out from the large discharge pipe 12. At this time, the high-viscosity slurry flows directly from the large discharge pipe 12, effectively preventing the discharge port from being blocked.

[0043] The above embodiments only express a glass reactor or several implementation methods of the utility model for preventing high and low viscosity slurry discharge from being blocked, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
