[0013] The beneficial effects of the present utility model are as follows:

[0014] 1.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-6As shown in the figure, a production and synthesis device for ethylene glycol glycidyl ether includes a support base 1, a processing barrel 2, and a sealing cover 3: The processing barrel 2 is arranged on the outer wall of the top end of the support base 1, and the sealing cover 3 is fitted on the outer wall of the top end of the processing barrel 2. A homogeneous mixing mechanism 4 is arranged inside the processing barrel 2, and a temperature control heating mechanism 6 is arranged outside the processing barrel 2. A dosage control mechanism 7 is arranged on the side of the temperature control heating mechanism 6. The homogeneous mixing mechanism 4 includes a limit support frame 41, a control motor 42, a transmission shaft 43, stirring blades 44, positioning rods 45, and a limit filter plate 46. The limit support frame 41 is arranged on the outer wall of the top end of the sealing cover 3, and the control motor 42 is arranged on the outer wall of the top end of the limit support frame 41. The control motor 42 is connected to the outer wall of the top end of the transmission shaft 43. The bottom end of the transmission shaft 43 is rotatably installed on the inner wall of the bottom end of the processing barrel 2. Stirring blades 44 are arranged outside the transmission shaft 43 inside the processing barrel 2. Positioning rods 45 are arranged on the outer side wall of the transmission shaft 43 at equal intervals in a circumferential manner. The limit filter plate 46 is arranged on the outer wall of the bottom end of the positioning rod 45; When it is necessary to accelerate the synthesis speed of ethylene glycol and glycerol, first, the control motor 42 needs to be turned on. Here, the setting of the limit support frame 41 plays an auxiliary supporting role for the control motor 42. When the control motor 42 is turned on, it will automatically drive the transmission shaft 43 to rotate. Subsequently, when the transmission shaft 43 rotates, it will automatically drive the stirring blades 44 and the positioning rods 45 to rotate synchronously. When the positioning rods 45 rotate, they will also drive the limit filter plate 46 to rotate synchronously.

[0025] The stirring blades 44 are arranged in a auger structure, and the limit filter plate 46 is arranged in a porous plate structure; Here, the design of arranging the stirring blades 44 in an auger structure enables the raw materials near it to be transported up and down automatically when the stirring blades 44 rotate, and the surrounding raw materials will immediately replenish towards the center, thus realizing the turning effect of the raw materials and achieving the longitudinal mixing of the raw materials. The design of arranging the limit filter plate 46 in a porous plate structure enables the raw materials inside the device to be mixed horizontally automatically along with the rotation trajectory of the limit filter plate 46. At the same time, the porous structure of the limit filter plate 46 will also synchronously disperse the raw materials, thereby greatly accelerating the mixing speed of ethylene glycol and glycerol.

[0026] A threaded ring 51 is arranged on the outer wall of the bottom end of the sealing cover 3, and a threaded groove 52 is opened on the outer wall of the top end of the processing barrel 2. The threaded ring 51 and the threaded groove 52 are installed in a threaded manner; Here, the connection relationship between the threaded ring 51 and the threaded groove 52 is used to make the processing barrel 2 and the sealing cover 3 in a detachable design, thereby synchronously facilitating the subsequent installation work of the two.

[0027] The temperature control heating mechanism 6 includes an annular support cover 61, an annular electric heating tube 62, a power supply component 63, a controller 64, and a protective cover 65. An annular support cover 61 is attached to the outer wall of the side at the bottom end of the processing barrel 2. An annular electric heating tube 62 is embedded and installed inside the annular support cover 61. A power supply component 63 and a controller 64 are arranged on the outer wall of the top end of the support base 1. A protective cover 65 is arranged outside the power supply component 63 and the controller 64. The outer wall of the bottom end of the protective cover 65 is connected to the outer wall of the top end of the support base 1. A temperature monitoring sensor 66 is arranged on the outer wall of the top end of the protective cover 65, and a heat conduction rod 67 is connected between the temperature monitoring sensor 66 and the outer wall of the side of the annular support cover 61; when it is necessary to raise the temperature inside the device for the synthesis reaction of ethylene glycol and glycerol, first, the temperature monitoring sensor 66 needs to be adjusted to a suitable monitoring range according to the synthesis temperature requirements of the two. Subsequently, the temperature monitoring sensor 66 is controlled to be turned on. Here, the setting of the heat conduction rod 67 facilitates timely transmitting the heating temperature value of the device to the temperature monitoring sensor 66. When the temperature inside the processing barrel 2 is lower than the monitoring range set by the temperature monitoring sensor 66, the temperature monitoring sensor 66 will automatically transmit the information to the controller 64. Subsequently, the controller 64 will automatically control the power supply component 63 to be turned on and energize the annular electric heating tube 62. Subsequently, the annular electric heating tube 62 is powered on and automatically heats up, and the inside of the processing barrel 2 is heated by heat transfer. Here, the setting of the annular support cover 61 plays an auxiliary installation effect on the annular electric heating tube 62. When the temperature inside the processing barrel 2 is higher than the monitoring range of the temperature monitoring sensor 66, the temperature monitoring sensor 66 will also transmit the information to the controller 64. Subsequently, the controller 64 will automatically control the power supply component 63 to be turned off to achieve the effect of stopping heating. Thus, through the above working process, the device can provide a suitable heating temperature environment for ethylene glycol and glycerol.

[0028] The dosage control mechanism 7 includes an auxiliary support plate 71, a metering cylinder 72, a storage barrel 73, a limit piston rod 74, a liquid inlet pipe 75 and a liquid outlet pipe 76. An auxiliary support plate 71 is provided on the outer wall of the side of the processing barrel 2 near the top position. Support columns are symmetrically provided on the outer wall of the bottom end of the auxiliary support plate 71, and the support columns are connected to the outer wall of the top end of the support base 1. A metering cylinder 72 and a storage barrel 73 are provided on the outer wall of the top end of the auxiliary support plate 71. A limit piston rod 74 is slidably installed inside the metering cylinder 72. A liquid inlet pipe 75 and a liquid outlet pipe 76 are conductively installed on the outer wall of the side of the metering cylinder 72. Check valves 77 are provided on the outside of both the liquid inlet pipe 75 and the liquid outlet pipe 76. The output end of the liquid inlet pipe 75 is conductively installed with the processing barrel 2. A delivery pipe 78 is conductively installed on the outer wall of the side of the storage barrel 73, and the delivery pipe 78 is connected to the liquid inlet end of the liquid inlet pipe 75; when it is necessary to control the feeding dosage of ethylene glycol or glycerol, the setting of the storage barrel 73 here is convenient for storing the ethylene glycol or glycerol stock solution. At the same time, the delivery pipe 78 on the side of the storage barrel 73 and the liquid inlet pipe 75 on the side of the metering cylinder 72 are designed to be detachable. As shown in the attached Figure 6 drawing of the specification, snap rings are provided on the outer walls of the joints where the two are butted, and the two snap rings are snap-fitted, thus facilitating the subsequent disassembly of the liquid inlet pipe 75 and the delivery pipe 78, and thus facilitating the replacement of the storage barrel 73 containing different stock solutions for stock solution delivery. Here, it should be noted that the metering cylinder 72 is set as a conventional transparent material cylinder with scale indicators on the outer wall. When it is necessary to feed liquid, only need to directly pull up the limit piston rod 74 until the piston pad at the bottom end of the limit piston rod 74 reaches the appropriate indicated scale position. When the limit piston rod 74 moves upward, the check valve 77 outside the liquid inlet pipe 75 will automatically open, and then the stock solution inside the storage barrel 73 will be drained and stored into the metering cylinder 72 via the delivery pipe 78 and the liquid inlet pipe 75. Subsequently, press down the limit piston rod 74. When the limit piston rod 74 moves downward, the check valve 77 outside the liquid outlet pipe 76 will automatically open, and at the same time, the stock solution stored inside the metering cylinder 72 will be drained and transported into the processing barrel 2 through the liquid outlet pipe 76, thus achieving the effect of quantitative liquid addition through the above comprehensive working process.

[0029] The output end of the one-way valve 77 outside the liquid inlet pipe 75 faces the metering cylinder 72, and the output end of the one-way valve 77 outside the liquid outlet pipe 76 faces the processing barrel 2. There is a complete sealed space between the metering cylinder 72 and the limit piston rod 74. The design that the output end of the one-way valve 77 outside the liquid inlet pipe 75 faces the metering cylinder 72 enables the original liquid inside the storage barrel 73 to smoothly enter the inside of the metering cylinder 72 when the above-mentioned limit piston rod 74 moves upward. The design that the output end of the one-way valve 77 outside the liquid outlet pipe 76 faces the processing barrel 2 enables the original liquid stored inside the metering cylinder 72 to smoothly flow into the inside of the processing barrel 2, controlling each other to avoid the problem of backflow. Making the space between the metering cylinder 72 and the limit piston rod 74 a complete sealed space enables the limit piston rod 74 to generate negative pressure inside the metering cylinder 72 when moving and smoothly complete the above-mentioned working process.

[0030] When the present utility model is in use, first, it is necessary to control the feeding doses of ethylene glycol and glycerol according to the dose required for controlling the production of ethylene glycol glycidyl ether. The setting of the storage barrel 73 here facilitates the storage of the original liquid of ethylene glycol or glycerol. At the same time, the conveying pipe 78 on the side of the storage barrel 73 and the liquid inlet pipe 75 on the side of the metering cylinder 72 are designed to be detachable. As shown in the attached Figure 6 illustration, snap rings are provided on the outer walls of the joints where the two are docked, and the two snap rings are snap-fitted, thus facilitating the subsequent disassembly of the liquid inlet pipe 75 and the conveying pipe 78, and thus facilitating the replacement of the storage barrel 73 containing different original liquids for the conveyance of the original liquid. Here, it is noted that the metering cylinder 72 is set as a conventional transparent material cylinder with scale indicators on the outer wall. When liquid inlet is required, only need to directly pull up the limit piston rod 74 until the piston pad at the bottom of the limit piston rod 74 reaches the appropriate indicated scale position. When the limit piston rod 74 moves upward, the one-way valve 77 outside the liquid inlet pipe 75 will automatically open at this time, and then the original liquid inside the storage barrel 73 will be drained through the conveying pipe 78 and the liquid inlet pipe 75 and stored inside the metering cylinder 72. Subsequently, press down the limit piston rod 74. When the limit piston rod 74 moves downward, the one-way valve 77 outside the liquid outlet pipe 76 will automatically open at this time, and at the same time, the original liquid stored inside the metering cylinder 72 will be drained through the liquid outlet pipe 76 and conveyed into the processing barrel 2 to drive the inside. Thus, the effect of quantitative liquid addition is achieved through the above-mentioned working process;

[0031] Subsequently, the drive control motor 42 is turned on. After the control motor 42 is turned on, it will automatically drive the transmission shaft 43 to rotate. Subsequently, when the transmission shaft 43 rotates, it will automatically drive the stirring blade 44 and the positioning rod 45 to rotate synchronously. When the positioning rod 45 rotates, it will also drive the limit filter plate 46 to rotate synchronously. Here, the stirring blade 44 is designed as a auger structure. When the stirring blade 44 rotates, it will automatically convey the raw materials near it up and down, and the surrounding raw materials will immediately replenish towards the center, thus realizing the turning effect of the raw materials and achieving the longitudinal mixing of the raw materials. The limit filter plate 46 is designed as a porous plate structure. Along with the rotation trajectory of the limit filter plate 46, it will automatically mix the raw materials inside the device horizontally. At the same time, the porous structure of the limit filter plate 46 will also synchronously disperse the raw materials, thereby greatly accelerating the mixing speed of ethylene glycol and glycerol;

[0032] When it is necessary to heat the inside of the device so that ethylene glycol and glycerol can undergo a synthesis reaction, first, the temperature monitoring sensor 66 needs to be adjusted to the appropriate monitoring range according to the synthesis temperature requirements of the two. Subsequently, the temperature monitoring sensor 66 is turned on. Here, the temperature conducting rod 67 is provided to facilitate timely transmission of the heating temperature value of the device to the temperature monitoring sensor 66. When the temperature inside the processing barrel 2 is lower than the monitoring range set by the temperature monitoring sensor 66, at this time, the temperature monitoring sensor 66 will automatically transmit the information to the controller 64. Subsequently, the controller 64 will automatically control the power supply component 63 to turn on and energize the annular electric heating tube 62. Subsequently, the annular electric heating tube 62 is powered on and automatically heats, and heats the inside of the processing barrel 2 through heat transfer. Here, the annular support cover 61 is provided to assist in installing the annular electric heating tube 62. When the temperature inside the processing barrel 2 is higher than the monitoring range of the temperature monitoring sensor 66, at this time, the temperature monitoring sensor 66 will also transmit the information to the controller 64. Subsequently, the controller 64 will automatically control the power supply component 63 to turn off to achieve the effect of stopping heating. Thus, through the above working process, the device can provide a suitable heating temperature environment for ethylene glycol and glycerol;

[0033] Thus, the synthesis effect of ethylene glycol and glycerol is completed. Subsequent cooling and purification can be carried out according to the existing operation technical means; it should be noted here that the above control motor 42 can be powered by existing technology. Whether it is powered by an external power supply component or an external wire, it belongs to the existing conventional operation technical means and will not be described in detail here.

[0034] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
