Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical synthesis, in particular to a high molecular weight polyether monomer synthesis feeding device. Background Art
[0002] Polyether, also known as polyethylene glycol ether, is currently the most popular synthetic oil. It is a linear polymer made from ethylene oxide, propylene oxide, butylene oxide, etc. through ring-opening homopolymerization or copolymerization under the action of a catalyst. It is a special engineering resin that has been industrially produced. It has the characteristics of high temperature resistance, radiation protection, self-flame retardancy, high strength and high modulus, and is widely used in the automotive, environmental protection, military, aerospace and other fields.
[0003] In the current existing technology, high molecular weight polyether may cause problems such as eye, respiratory and skin irritation under long-term exposure. In addition, during the processing of high molecular weight polyether, high molecular weight polyether will produce some harmful gases and vapors, such as carbon monoxide, carbon dioxide and nitrates, which may also pose potential hazards to the working environment and workers. However, when the high molecular weight polyether is fed, the harmful substances inside the accumulated high molecular weight polyether will accumulate inside the high molecular weight polyether and cannot be effectively discharged. As a result, when employees collect the accumulated high molecular weight polyether, the dense gas accumulated inside the high molecular weight polyether will suddenly burst out, causing the employees to be sprayed in the face by the sudden harmful gas, resulting in harm to the employees.
[0004] Therefore, in view of the above problems, a high molecular weight polyether monomer synthesis feeding device is proposed. Utility Model Content

[0013] Beneficial effects of the utility model:
[0014] The utility model provides a high molecular weight polyether monomer synthesis feeding device, which cooperates with a differentiation screen plate to accumulate the high molecular weight polyether, and cooperates with a pair of conveyor belts of a motor for transmission. When the differentiation screen plate rotates, the high molecular weight polyether on the top surface of the differentiation screen plate is driven to move together. After the differentiation screen plate rotates, the differentiation soft scraper on the outer surface of the limiting ring is cooperated to smooth and push the high molecular weight polyether accumulated on the top surface of the differentiation screen plate, so that the high molecular weight polyether is uniformly infiltrated on the surface of the differentiation screen plate. While the high molecular weight polyether is uniformly infiltrated, harmful gases on the surface of the high molecular weight polyether are gradually diffused out. Under the suction of the blower, the diffused harmful gases are absorbed and guided to the inside of the spray tower to purify the harmful gases, thereby greatly reducing the accumulation and escape of harmful gases on and inside the high molecular weight polyether.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Specific examples are given below.
[0026] See also Figures 1-6The utility model provides a high molecular weight polyether monomer synthesis feeding device, comprising a feeding platform 11 and a closed top cover 111 arranged on the outer surface of the top of the feeding platform 11, an exhaust sleeve 12 fixedly mounted on the outer surface of the top of the closed top cover 111, a feeding cylinder 13 fixedly mounted on the top surface of the closed top cover 111 and located at a side edge position, a second motor 14 arranged on the feeding platform 11 and a side surface of the closed top cover 111, a second fixing ring 131 fixedly connected to the inner wall surface of the feeding cylinder 13, and a second fixing ring 131 located at the top edge position of the second fixing ring 131. A limiting ring 136 is fixedly connected to the upper portion, a differentiation screen plate 132 is movably sleeved on the top surface of the fixing ring 2 131, a support rod 133 is fixedly connected to the top surface of the differentiation screen plate 132, a differentiation soft scraper 137 movably sleeved on the top outer surface of the differentiation screen plate 132 is fixedly connected to the inner wall surface of the limiting ring 136, a motor 134 is fixedly mounted on the top outer surface of the feeding cylinder 13, a conveying crawler 135 movably sleeved on the outer surface of the support rod 133 is provided on the output end of the motor 134, and a blower 112 is fixedly mounted on the outer surface of the feeding platform 11;
[0027] During operation, the high molecular weight polyether is put into the inside of the feeding barrel 13, and the high molecular weight polyether is accumulated in cooperation with the differentiation screen plate 132. At the same time, the conveying crawler 135 is driven by the motor 134, thereby driving the support rod 133 on the top surface of the differentiation screen plate 132 to rotate on the top surface of the fixing ring 2 131. When the differentiation screen plate 132 rotates, it drives the high molecular weight polyether on the top surface of the differentiation screen plate 132 to move together. After the differentiation screen plate 132 rotates, the differentiation soft scraper 137 on the outer surface of the limiting ring 136 accumulates the high molecular weight polyether on the top surface of the differentiation screen plate 132. The high molecular weight polyether is smoothed and pushed, so that the high molecular weight polyether on the top surface of the differentiation sieve plate 132 is stirred under the push of the differentiation soft scraper 137, so that the high molecular weight polyether penetrates evenly on the surface of the differentiation sieve plate 132. While the high molecular weight polyether penetrates evenly, the harmful gas on the surface of the high molecular weight polyether will gradually diffuse out. With the help of the suction of the blower 112, the diffused harmful gas is absorbed and the harmful gas is diverted to the inside of the spray tower to purify the harmful gas, which greatly reduces the accumulation and escape of harmful gas on the surface and inside of the high molecular weight polyether.
[0028] Further, such as Figures 1 to 6As shown, the output end of the motor 2 14 is fixedly connected to a transmission rod 141, and a triangular differentiation plate 142 is fixedly connected to the outer surface of the transmission rod 141. A stirring arc plate 143 is fixedly connected to one end of the triangular differentiation plate 142. The outer surfaces of the stirring arc plate 143 are movably sleeved on the inner wall of the feeding table 11 and the closed top cover 111 respectively. An air guide pipe 113 is fixedly connected to the output end of the blower 112. One end of the air guide pipe 113 is fixedly connected to the outer surface of the top end of the exhaust sleeve 12. The outer surface of the feeding table 11 is fixed. A support leg 114 is fixedly connected to the inner wall of the exhaust sleeve 12, a fixing ring 121 is fixedly connected to the top surface of the fixing ring 121, a limiting rod 122 is fixedly connected to the outer surface of the limiting rod 122, an arc-shaped groove 124 is provided on the outer bottom surface of the conical sleeve 123, an elastic wire 125 is fixedly connected to the outer surface of the conical sleeve 123, and a support frame 138 movably sleeved on the outer surface of the support rod 133 is fixedly connected to the outer surface of the feed barrel 13.
[0029] During operation, as the high molecular weight polyether is evenly scattered from the inside of the feeding barrel 13 into the inside of the feeding platform 11, the motor 2 14 is coordinated to rotate the transmission rod 141, so that the triangular differentiation plate 142 and the stirring arc plate 143 on the outer surface of the transmission rod 141 flip the high molecular weight polyether inside the feeding platform 11, thereby diffusing the harmful gas on the high molecular weight polyether itself, and then utilizing the narrow space inside the feeding platform 11 and the closed top cover 111 to make the harmful gas accumulate inside the feeding platform 11, and then the blower 112 absorbs the gas to the air guide pipe 113, so that the gas accumulated on the feeding platform 11 is discharged. The harmful gas in the internal space of the closed top cover 111 flows into the interior of the blower 112 along with the flow of the gas. As the gas is continuously absorbed, the feeding platform 11 and the outlet of the closed top cover 11 will absorb the outside air into the feeding platform 11. The inlet of the feeding cylinder 13 at the other end of the feeding platform 11 will also guide the outside air into the interior of the feeding platform 11. When the gas at both ends of the feeding platform 11 enters the interior of the feeding platform 11 at the same time, the escape of the internal harmful gas can be effectively reduced, and then the harmful gas is infused into the interior of the spray tower through the blower 112 for purification.
[0030] Working principle: put the high molecular weight polyether into the inside of the feeding barrel 13, cooperate with the differentiation screen plate 132 to pile up the high molecular weight polyether, and cooperate with the motor 134 to drive the conveyor belt 135, thereby driving the support rod 133 on the top surface of the differentiation screen plate 132 to rotate on the top surface of the fixed ring 2 131. When the differentiation screen plate 132 rotates, it will drive the high molecular weight polyether on the top surface of the differentiation screen plate 132 to move together. After the differentiation screen plate 132 rotates, it cooperates with the differentiation soft scraper 137 on the outer surface of the limiting ring 136 to pile up the high molecular weight polyether on the top surface of the differentiation screen plate 132. The high molecular weight polyether is smoothed and pushed, so that the high molecular weight polyether on the top surface of the differentiation screen plate 132 is stirred under the push of the differentiation soft scraper 137, so that the high molecular weight polyether is evenly penetrated on the surface of the differentiation screen plate 132. While the high molecular weight polyether is evenly penetrated, the harmful gas on the surface of the high molecular weight polyether will gradually diffuse out. Under the suction of the blower 112, the diffused harmful gas is absorbed and the harmful gas is guided to the inside of the spray tower for purification, thereby greatly reducing the accumulation and escape of harmful gas on and inside the high molecular weight polyether.
[0031] As the high molecular weight polyether is evenly scattered from the inside of the feeding barrel 13 into the inside of the feeding table 11, the motor 2 14 is coordinated to rotate the transmission rod 141, so that the triangular differentiation plate 142 and the stirring arc plate 143 on the outer surface of the transmission rod 141 flip the high molecular weight polyether inside the feeding table 11, thereby diffusing the harmful gas on the high molecular weight polyether itself, and then utilizing the narrow space inside the feeding table 11 and the closed top cover 111 to make the harmful gas accumulate inside the feeding table 11, and then the blower 112 absorbs the gas to the air guide pipe 113, so that the gas accumulated in the closed top cover 111 is discharged. The harmful gas in the internal space of the top cover 111 flows into the interior of the blower 112 along with the flow of the gas. As the gas is continuously absorbed, the feeding platform 11 and the outlet of the closed top cover 111 will absorb the outside air into the feeding platform 11. The inlet of the feeding cylinder 13 at the other end of the feeding platform 11 will also guide the outside air into the interior of the feeding platform 11. When the gas at both ends of the feeding platform 11 enters the interior of the feeding platform 11 at the same time, the escape of the internal harmful gas can be effectively reduced, and then the harmful gas is infused into the interior of the spray tower through the blower 112 for purification.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
