Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a glass-lined electrically heated reaction vessel for the production of pyrimidine phenyl esters. Background Technology

[0002] An electrically heated glass-lined reactor is made by lining the inner surface of a steel container with high-silica glass, which is then firmly bonded to the metal surface through high-temperature firing, thus becoming a composite material product. Therefore, it has the dual advantages of the stability of glass and the strength of metal, making it an excellent corrosion-resistant device. It has been widely used in chemical, petroleum, pharmaceutical, pesticide, and food industries. In the production process of pyrimidine phenyl ester, an electrically heated glass-lined reactor is required.

[0003] The existing glass-lined electrically heated reactor for the production of pyrimidine phenyl esters has several drawbacks: during the intermediate reaction process, feeding is required based on trigger points such as temperature and concentration. The existing intermediate feeding mechanism has low feeding accuracy, and the gas generated during the reaction is prone to leaking out through the feeding pipe. Therefore, there is room for improvement. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1: Combination Figure 1-4 As shown, this embodiment provides a glass-lined electrically heated reactor for the production of pyrimidine phenyl esters, including: a main body 100 and a feeding mechanism 200.

[0021] The main structure 100 includes a vessel body 110, a feed pipe 120 installed at the top of the vessel body 110, a discharge pipe 130 installed at the bottom of the vessel body 110, and a stirring element 140 installed at the top of the vessel body 110 and extending into the inner cavity of the vessel body 110.

[0022] The vessel body 110 provides space for the reaction and is configured with a double-shell structure. Electric heating tubes are arranged in an array in the sandwich of the double shell structure to heat the inner cavity of the vessel body 110. The feed pipe 120 is used to facilitate the feeding of materials into the vessel body 110. The discharge pipe 130 includes a discharge pipe 131 installed at the bottom of the vessel body 110 and an electric valve 132 installed on the discharge pipe 131. The discharge pipe 131 is used to discharge the reactants from the inner cavity of the vessel body 110, and the electric valve 132 is used to control the opening and closing of the discharge pipe 131.

[0023] The stirring component 140 includes a motor 141 fixed to the top of the vessel body 110 with its shaft extending into the inner cavity of the vessel body 110, a rotating shaft 142 with its end fixed to the shaft of the motor 141, and multiple sets of blades 143 fixed in a ring array on the rotating shaft 142. When the motor 141 is started, it drives the rotating shaft 142 to rotate, and the rotation of the rotating shaft 142 drives the blades 143 to rotate, thereby stirring the raw materials in the reaction vessel, making them mixed evenly, and enabling a stable reaction.

[0024] The feeding mechanism 200 is used to facilitate feeding during the reaction process. It includes a feeding pipe 210 fixed to the top of the vessel body 110 and extending into the inner cavity of the vessel body 110, a support 220 fixed to one side of the vessel body 110, multiple support rods 230 fixed to the top of the support 220 in a ring array, a weighing element 240 fixed on the support rod 230, a storage cylinder 250 slidably sleeved on the support rod 230 and with its bottom end close to the weighing element 240, a pump 260 installed at the bottom of the storage cylinder 250, a flexible hose 270 with one end connected to the pump 260 and the other end connected to the feeding pipe 210, a sealing cap 280 installed at the top of the storage cylinder 250 by a threaded connection, and a sealing element 290 movably installed on the feeding pipe 210.

[0025] The feeding pipe 210 includes a circular pipe 211 that passes through the top of the vessel body 110 and an inclined pipe 212 that is fixed to one side of the circular pipe 211 and communicates with the inner cavity of the circular pipe 211. The circular pipe 211 is used to feed the raw material into the inner cavity of the vessel body 110. The inclined pipe 212 is used to facilitate the entry of the raw material into the circular pipe 211, and at the same time, it can ensure that the raw material inside can enter the circular pipe 211 along the inclined pipe 212 under the action of gravity, avoiding residue.

[0026] Support 220 is used to fix support rod 230, support rod 230 is used for storage cylinder 250, weighing component 240 includes protrusion 241 fixed on support rod 230 and mass sensor 242 fixed on protrusion 241. Sleeve 251 is fixed in a ring array on the outer side of storage cylinder 250. Sleeve 251 is slidably sleeved on support rod 230, and the bottom end of sleeve 251 is close to mass sensor 242. Through this setting, mass sensor 242 can monitor the change of raw material in storage cylinder 250 in real time.

[0027] Storage cylinder 250 is used to store raw materials. Pump 260 is fixed at the bottom of storage cylinder 250. The inlet of pump 260 is connected to the inner cavity of storage cylinder 250, and the outlet is connected to inclined pipe 212 through hose 270, so as to facilitate pumping the raw materials in storage cylinder 250 into feeding pipe 210. In addition, the height of pump 260 is higher than the height of inclined pipe 212 to avoid raw materials remaining in hose 270.

[0028] The sealing cover 280 includes a cover plate 281 that is threadedly installed on the top of the storage cylinder 250 and a liquid level sensor 282 that is installed on the cover plate 281 and extends into the inner cavity of the storage cylinder 250. The cover plate 281 is used to seal the storage cylinder 250, and the liquid level sensor 282 is used to monitor the liquid level of the raw material in the storage cylinder 250 in real time.

[0029] The sealing component 290 is used to seal the bottom end of the feeding pipe 210 after feeding is completed. It includes a round rod 291 that moves through the feeding pipe 210, a conical seat 292 fixed to the bottom end of the round rod 291, and an electric telescopic rod 293 fixed to the top of the vessel body 110 and fixedly connected to the end of the round rod 291. During feeding, the electric telescopic rod 293 extends and drives the conical seat 292 to move down through the round rod 291, so that the bottom of the feeding pipe 210 is opened, which facilitates the delivery of raw materials in the feeding pipe 210. After feeding is completed, the electric telescopic rod 293 retracts and drives the conical seat 292 to move up through the round rod 291 and close to the bottom end of the feeding pipe 210, thus sealing the feeding pipe 210 and preventing gas from seeping out through the feeding pipe 210 during the reaction process.

[0030] The working principle and usage process of this utility model are as follows: When it is necessary to add material during the reaction process, the electric telescopic rod 293 is activated, which drives the conical seat 292 to move downward through the round rod 291, opening the bottom end of the feeding pipe 210. At this time, the pump 260 is activated, pumping the raw material in the storage cylinder 250 into the feeding pipe 210 through the hose 270. The raw material falls into the reactor body 110 through the feeding pipe 210, realizing the feeding operation. At the same time, the mass sensor 242 monitors the mass reduction of the raw material in the storage cylinder 250 in real time. When the mass reduction of the raw material in the storage cylinder 250 is equal to the set feeding mass, the pump 260 is turned off, thus completing the addition of raw material. At the same time, the electric telescopic rod 293 retracts, which drives the conical seat 292 to move upward through the round rod 291 and close to the bottom end of the feeding pipe 210, sealing the feeding pipe 210.
