Abstract
Description
Technical Field
[0001] This utility model relates to the field of methylindole technology, and in particular to a methylindole synthesis reactor. Background Technology
[0002] 3-Methylindole is an organic compound with a fecal odor, also known as skatole. It is a white or slightly brownish crystal that is sensitive to light and gradually turns brown over time. It is soluble in hot water, alcohols, benzene, chloroform, and ethers. It reacts with potassium ferrocyanide and sulfuric acid to produce a purple color. It can be used as a biochemical reagent and also for making fragrances. In the synthesis of 3-methylindole, a reaction vessel is required to allow the raw materials to undergo a synthesis reaction under specific conditions.
[0003] The existing 3-methylindole synthesis reactor does not purify or adsorb the gases generated during the synthesis reaction, which easily leads to some of the reaction gases leaking into the external environment, resulting in low practicality. Utility Model Content
[0004] This invention provides a methylindole synthesis reactor, which solves the problem that existing 3-methylindole synthesis reactors do not purify and adsorb the gases generated during the synthesis reaction, and are prone to leakage of some reaction gases into the external environment, resulting in low practicality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A methylindole synthesis reactor includes a reactor body, a heat exchange box on one side of the reactor body, and a cover on the heat exchange box. The heat exchange box contains a stirring mechanism, which includes a motor, a stirring shaft connected to one end of the motor output shaft via a coupling, a mounting ring connected to the outer wall of the stirring shaft via a pin, and several stirring blades respectively fixed to the outer wall of the mounting ring. The heat exchange box contains a heat exchange mechanism, which includes a heat-conducting plate, several heat exchange plates fixed to one side of the outer wall of the heat-conducting plate, a mounting cover fixed to one side of the outer wall of the heat exchange box, and several fans respectively bolted to the bottom outer wall of the mounting cover. The cover contains several purification mechanisms, each consisting of a mounting cylinder threaded through and screwed to the outer wall of the cover, a return spring sleeved within the mounting cylinder, a compression ring slidably sleeved within the mounting cylinder, a connecting rod, a piston bolted to the bottom outer wall of the connecting rod, a purification cylinder abutting against the top outer wall of the compression ring, and a filter element embedded within the purification cylinder.
[0007] Preferably, a water inlet pipe is fixedly installed on the upper inner wall of one side of the heat exchange box, and a water outlet pipe is fixedly installed on the lower inner wall of one side of the heat exchange box. The box cover is bolted to the top outer wall of the heat exchange box.
[0008] Preferably, a connecting pipe is fixed on the outer wall of the bottom of the box cover, and one end of the connecting pipe is connected to the outer wall of the exhaust end of the reactor body through a flange. A pressure relief valve is clamped on the outer wall of one end of the connecting pipe.
[0009] Preferably, a mounting bracket is fixed on one side of the outer wall of the heat exchange box, and the motor is connected to the outer wall of the mounting bracket by bolts. One end of the stirring shaft is connected to the inner wall of the heat exchange box by a bearing.
[0010] Preferably, two connecting plates are bolted to the inner wall of the middle part of the heat exchange box, and the two ends of the heat conduction plate are respectively fixed to the outer wall of the opposite side of the two connecting plates. Several heat exchange plates are respectively penetrated and fixed to the outer wall of one side of the heat exchange box, and an exhaust pipe is fixed to the inner wall of the top of the mounting cover.
[0011] The above scheme involves using a connecting pipe to transport the high-temperature reaction gas from the reactor body to the heat exchange box. The reaction gas first exchanges heat with the cold water in the heat exchange box, and then the heat-conducting plate and multiple heat exchange plates exchange heat with the hot water in the heat exchange box. At the same time, the motor drives the stirring shaft and multiple stirring blades to rotate, stirring the hot water in the heat exchange box, so that the hot water can fully contact the heat-conducting plate and multiple heat exchange plates. Then, the fan dissipates heat from one end of the heat exchange plate, so that the hot air is discharged from the exhaust pipe into the waste heat recovery equipment.
[0012] Preferably, a cross-shaped connecting frame is fixed on the inner wall of the extrusion ring, and a connecting rod is fixed on the bottom outer wall of the connecting frame. The outer diameter of the piston is adapted to the inner diameter of the lower part of the mounting cylinder, and a sealing ring is fixed on the outer wall of the piston. A threaded ring is fixed on the upper inner wall of the mounting cylinder, and the purification cylinder is screwed into the threaded ring. An exhaust cap is screwed onto the upper inner wall of the purification cylinder.
[0013] The above method involves the filter element contacting the heat-exchanged reaction gas to adsorb and purify it. When one of the filter elements needs to be replaced, the purification cylinder is rotated to raise it. At this time, the squeezing ring slowly returns to its original position under the tension of the return spring. The squeezing ring drives the connecting frame, connecting rod, and piston to rise. The piston seals the lower part of the mounting cylinder. Then, the exhaust cover and filter element can be removed to replace the filter element.
[0014] The beneficial effects of this utility model are as follows:
[0015] The filter element comes into contact with the reacting gas after heat exchange, thereby adsorbing and purifying the reacting gas. When one of the filter elements needs to be replaced, the purification cylinder is rotated to make the purification cylinder rise. At this time, the squeezing ring slowly returns to its original position under the tension of the return spring. The squeezing ring drives the connecting frame, connecting rod and piston to rise. The piston seals the lower part of the mounting cylinder. Then the exhaust cover and filter element can be removed to replace the filter element. It can adsorb and purify the reacting gas after heat exchange, and the filter element can be replaced without stopping the machine, which improves its practicality. Attached Figure Description
