Description

Technical Field

[0001] The invention belongs to the technical field of reactors and relates to a pharmaceutical reactor which is convenient for removing floating foam. Background Art

[0002] The broad understanding of a reactor is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; the materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based alloys and other composite materials;

[0003] In the pharmaceutical industry, reactors are widely used in various pharmaceutical steps. When the raw materials of the pharmaceuticals are fully stirred and reacted in the reactor, a lot of foam will be generated on the upper end of the liquid surface. The foam will reduce the quality of the pharmaceuticals. The operator is required to open the upper cover of the reactor after the reaction and then skim off the foam through a screen. In addition, there is a stirring mechanism in the middle of the reactor, so there are many operating steps and it is more difficult.

[0004] Based on this, we designed a pharmaceutical reactor that is easy to remove foam. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to propose a pharmaceutical reaction kettle that is convenient for removing froth. The technical problem to be solved by the device is: how to remove the froth generated by the reaction kettle when making medicine.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0008] The working principle of the present invention is as follows: during the process of using the reaction kettle to make medicine, the driving mechanism can drive the rotating tube to rotate, and then drive the lifting block and the two rotary arms to rotate, so as to achieve the stirring effect. After the reaction is completed, the lifting block and the two rotary arms are driven to rise by the lifting mechanism, and rise until the liquid level is located between the upper and lower edges of the oblique scraping strip. Then, after the liquid level is calm, the opening and closing mechanism is first opened to connect the groove with the through hole, and then the driving mechanism is used to drive the rotating tube to rotate slowly. At this time, the floating foam is affected by the oblique scraping strip and the rotary arm, enters the through hole along the groove, and is discharged after passing through the lifting tube downward along the through hole. The steps for removing the floating foam are simple and the operation is convenient. After skimming off the floating foam, the opening and closing mechanism is closed to block the connection between the through hole and the groove, and then the lifting block and the rotary arm are moved downward by the lifting mechanism, so that the stirring function can be continued.

[0009] The driving mechanism includes a rotating plate fixed to the upper end of the rotating tube, a circular hole is opened in the middle of the rotating plate, a thrust bearing is arranged between the rotating plate and the tank body, and a connecting frame is fixed to the rotating plate, a motor frame is fixed to the upper end of the tank body, a driving motor is installed on the upper end of the motor frame, the output shaft of the driving motor passes through the motor frame, and its end is fixedly connected to the connecting frame.

[0010] With the above structure, when in use, the driving motor is started to drive the connecting frame and the rotating plate to rotate, thereby driving the rotating tube to rotate, and the lower end of the rotating tube is connected to the tank body through a rotating joint to ensure that the rotating tube can rotate without causing leakage of the tank body.

[0011] The lifting mechanism includes a mounting plate and a bearing seat fixed above the rotating plate, and a rotating shaft is rotatably arranged between the mounting plate and the bearing seat, a rotating motor for driving the rotating shaft to rotate is installed on the mounting plate, a winding roller is fixed on the rotating shaft, and a steel wire is wound on the winding roller, the other end of the steel wire passes through the circular hole, and its end is connected to the opening and closing mechanism.

[0012] By adopting the above structure, when in use, the motor is rotated to drive the winding roller to rotate, so that the steel wire can be retracted and released. When the steel wire is reeled in, the lifting block will be lifted upward. When the steel wire is released, the lifting block slides downward under the action of gravity, thereby achieving the effect of controlling the up and down movement of the lifting block.

[0013] The opening and closing mechanism includes a lifting cylinder, a fixed cylinder and a spring. The lifting cylinder is slidably arranged inside the through hole. The fixed cylinder is fixed to the upper end of the lifting block, and the lower end of the fixed cylinder is connected to the through hole. A through hole is opened at the upper end of the fixed cylinder, and the end of the steel wire passes through the through hole and is fixedly connected to the lifting cylinder. The spring is located inside the fixed cylinder, and the two ends of the spring are respectively against the upper edge of the fixed cylinder and the top of the lifting cylinder. A locking assembly for fixing the lifting block is provided on the rotating rod.

[0014] When the lifting block is in use, the steel wire is wound upward, the steel wire drives the lifting cylinder to move upward, and the lifting cylinder drives the lifting block and the components connected to the lifting block to move upward synchronously, and at this time, under the action of gravity of the lifting block and its connecting components, the spring is compressed to the shortest state, and when the lifting block is fixed by the locking assembly, the steel wire is released downward, and the spring can be extended to push the lifting cylinder downward, and the lifting cylinder can release the seal of the connection between the through hole and the groove. Conversely, when the lifting block needs to be moved downward, the steel wire can be wound up, so that the spring is compressed to the shortest again, and the lifting cylinder blocks the connection between the through hole and the groove again, and then the locking assembly is released to unlock the lifting block, and then the steel wire is released, and the lifting block and its connecting components will move downward and reset synchronously with the lifting cylinder under the action of gravity.

[0015] The locking assembly includes two symmetrically distributed fixing columns fixed on the upper surface of the lifting block, a conical head is fixed on the upper end of the fixing column, and an inverted cone ring is slidably arranged on the fixing column, a telescopic tube is arranged below the rotating plate, and a slider is fixed at the lower end of the telescopic tube, the slider is slidably arranged inside the rotating tube, a wire hole is opened in the middle position of the slider, and a steel wire passes through the wire hole, two symmetrically distributed locking cylinders are fixed on both sides of the slider, a square hole is opened on the side wall of the locking cylinder close to the slider, a through hole is opened inside the slider, the through hole is directly opposite to the square hole, locking tongues are slidably arranged at both ends of the through hole, and the end of the lock tongue passes through the square hole at the corresponding position, a first magnetic block is fixed on the back of the lock tongue, and two second magnetic blocks are fixed inside the through hole, and the first magnetic block and the second magnetic block at the corresponding position are opposite to each other with the same pole.

[0016] With the above structure, when in use, as the lifting block moves upward, the fixed column is inserted into the locking cylinder at a position, and the lock tongue is squeezed into the through hole by the conical head. After the conical head rises above the lock tongue, the lock tongue is extended under the repulsive force of the first magnetic block and the second magnetic block. At this time, the upper surface of the lock tongue is against the lower surface of the conical head, and the lifting block will be restricted from moving downward. At this time, the steel wire is released, and the spring will squeeze the lifting cylinder downward to release the seal on the connection between the through hole and the groove. When the foam is removed, the steel wire is reeled in. At this time, the lifting cylinder moves upward and compresses the spring. When the spring is compressed to the shortest state, continuing to reel in the steel wire will drive the lifting block upward The lifting block moves upward, and the locking tongue shrinks toward the inside of the through hole under the extrusion of the inverted cone ring. After the inverted cone ring rises above the locking tongue, the locking tongue extends out under the repulsive force of the first magnetic block and the second magnetic block, and then the steel wire is released. At this time, the lifting block descends under the action of gravity. At this time, the inverted cone ring will not move downward with the lifting block under the action of the locking tongue. As the fixed column descends, the inverted cone ring fits against the conical head and is squeezed downward by the conical head. At this time, the locking tongue shrinks toward the inside of the through hole again under the extrusion of the lower surface of the inverted cone ring. At this time, the locking tongue will pass over the inverted cone ring and the conical head. At this time, the restricting effect on the lifting block can be lifted, the steel wire is continued to be released, and the lifting block can move downward.

[0017] The telescopic tube includes a threaded sleeve rotatably arranged in a circular hole, a rotating member is fixed on the upper end of the threaded sleeve, a plurality of handles distributed at equal intervals are fixed on the side end of the rotating member, a small hole is opened in the rotating member, a threaded tube is fixed on the upper end of the slider, and the upper end of the threaded tube is threadedly connected to the threaded sleeve, and a steel wire passes through the small hole, the threaded sleeve and the threaded tube.

[0018] With the above structure, in actual use, the slider cannot rotate if the rotating tube does not rotate. At this time, the operator can rotate the rotating part to drive the threaded sleeve to rotate, and then adjust the height of the threaded tube and the slider, so that when the lifting block is locked, the liquid level in the tank body is located between the upper and lower edges of the oblique scraper strip.

[0019] A bellows is fixed to the upper end of the fixed cylinder, and a sealing plate is fixed to the upper end of the bellows, and the sealing plate is fixedly connected to the steel wire.

[0020] With the above structure, the bellows can seal the perforation while the steel wire rises and falls, preventing the liquid inside the tank from entering the fixed tube.

[0021] Compared with the prior art, the pharmaceutical reactor that is convenient for removing foam has the following advantages:

[0022] 1. Through the lifting block, the swing arm, the lifting mechanism, the driving mechanism and the opening and closing mechanism, the floating foam inside the tank body can be removed through the swing arm which plays a stirring role, and the operator does not need to open the tank body. The operation steps are convenient and the difficulty is relatively low.

[0023] 2. Through the opening and closing mechanism and the lifting mechanism, one power source can realize the lifting and locking of the lifting block, and the power source is set outside the tank, which reduces the production and maintenance costs of the equipment.

[0024] 3. Through the telescopic tube, the locking position of the lifting block can be adjusted according to the height of the liquid level inside the tank, which can achieve the effect of removing floating foam and expand the application scope of the device. BRIEF DESCRIPTION OF THE DRAWINGS

After the reaction is completed, the lifting block 7 and the two rotary arms 10 are driven to rise by the lifting mechanism 13 until the liquid level is located between the upper and lower edges of the inclined scraper 12, and then after the liquid level is calm, the opening and closing mechanism is first opened. 14 is opened, so that the groove 11 is connected with the through hole 9, and then the driving mechanism 6 drives the rotating tube to rotate slowly. At this time, the floating foam is affected by the oblique scraping strip 12 and the rotary arm 10, enters the through hole 9 along the groove 11, and is discharged after passing through the lifting pipe 15 downward along the through hole 9.

[0044] The lifting mechanism 13 includes a mounting plate 1301 and a bearing seat 1302 fixed above the rotating plate 601, and a rotating shaft 1303 is rotatably arranged between the mounting plate 1301 and the bearing seat 1302, a rotating motor 1304 for driving the rotating shaft 1303 to rotate is installed on the mounting plate 1301, a winding roller 1305 is fixed on the rotating shaft 1303, and a steel wire 1306 is wound around the winding roller 1305, the other end of the steel wire 1306 passes through the circular hole 606, and its end is connected to the opening and closing mechanism 14; when in use, the rotating motor 1304 rotates to drive the winding roller 1305 to rotate, so as to realize the retraction and release of the steel wire 1306, when the steel wire 1306 is wound, the lifting block 7 will be lifted upward, and when the steel wire 1306 is released, the lifting block 7 slides downward under the action of gravity, thereby realizing the effect of controlling the lifting block 7 to move up and down.

[0045] The opening and closing mechanism 14 includes a lifting cylinder 1401, a fixed cylinder 1402 and a spring 1404. The lifting cylinder 1401 is slidably arranged inside the through hole 9.

The parts connected to the lowering block 7 move up synchronously, and at this time, under the action of gravity of the lifting block 7 and its connected parts, the spring 1404 is compressed to the shortest state. When the lifting block 7 is fixed by the locking assembly, the steel wire 1306 is released downward. At this time, the spring 1404 can be extended and push the lifting cylinder 1401 downward. At this time, the lifting cylinder 1401 can release the seal on the connection between the through hole 9 and the groove 11.

Then, the locking assembly is released to lock the lifting block 7, and then the steel wire 1306 is released.

[0046] The locking assembly includes two symmetrically distributed fixed columns 1405 fixed on the upper surface of the lifting block 7, a conical head 1406 is fixed on the upper end of the fixed column 1405, and an inverted cone ring 1407 is slidably arranged on the fixed column 1405, a telescopic tube is arranged below the rotating plate 601, and a slider 1408 is fixed at the lower end of the telescopic tube, the slider 1408 is slidably arranged inside the rotating tube 2, a wire hole 1409 is opened in the middle position of the slider 1408, and the steel wire 1306 passes through the wire hole 1409, two symmetrically distributed locking cylinders 1410 are fixed on both sides of the slider 1408, a square hole 1412 is opened on the side wall of the locking cylinder 1410 close to the slider 1408, and a through hole 1411 is opened inside the slider 1408, and the through hole 1411 is directly Lock tongues 1413 are slidably provided at both ends of the square hole 1412 and the through hole 1411, and the end of the lock tongue 1413 passes through the square hole 1412 at the corresponding position, a first magnetic block 1414 is fixed to the back of the lock tongue 1413, and two second magnetic blocks 1415 are fixed inside the through hole 1411, and the first magnetic block 1414 and the second magnetic blocks 1415 at the corresponding position are opposite to each other with the same pole; when in use, as the lifting block 7 moves upward, the fixed column 1405 is inserted into the locking cylinder 1410 at a position, at this time, the lock tongue 1413 is squeezed into the through hole 1411 by the conical head 1406, and after the conical head 1406 rises above the lock tongue 1413, the repulsive force of the first magnetic block 1414 and the second magnetic block 1415 When the lifting block 7 moves upward, the locking tongue 1413 extends out. At this time, the upper surface of the locking tongue 1413 abuts against the lower surface of the conical head 1406, and the lifting block 7 is restricted from moving downward. At this time, the steel wire 1306 is released, and the spring 1404 squeezes the lifting cylinder 1401 downward to release the seal at the connection between the through hole 9 and the groove 11. When the floating foam is removed, the steel wire 1306 is reeled in. At this time, the lifting cylinder 1401 moves upward and compresses the spring 1404. When the spring 1404 is compressed to the shortest state, continuing to reel in the steel wire 1306 will drive the lifting block 7 to move upward. As the lifting block 7 moves upward, the locking tongue 1413 shrinks toward the inside of the through hole 1411 under the squeezing action of the inverted cone ring 1407. After the inverted cone ring 1407 rises to above the locking tongue 1413, Under the repulsive force of the first magnetic block 1414 and the second magnetic block 1415, the locking tongue 1413 extends out, and then the steel wire 1306 is released. At this time, the lifting block 7 descends under the action of gravity. At this time, the inverted cone ring 1407 will not move downward with the lifting block 7 under the action of the locking tongue 1413. As the fixed column 1405 descends, the inverted cone ring 1407 fits with the conical head 1406 and is squeezed downward by the conical head 1406. At this time, the locking tongue 1413 is squeezed by the lower surface of the inverted cone ring 1407 and shrinks toward the through hole 1411 again. At this time, the locking tongue 1413 can pass over the inverted cone ring 1407 and the conical head 1406. At this time, the restriction effect on the lifting block 7 can be lifted, and the steel wire 1306 continues to be released, and the lifting block 7 can move downward.

At this time, the operator can rotate the rotating member 1417 to drive the threaded sleeve 1416 to rotate, and then adjust the height of the threaded tube 1420 and the slider 1408, so that when the lifting block 7 is locked, the liquid level in the tank body 1 is located between the upper and lower edges of the oblique scraper strip 12.

[0048] A bellows 1421 is fixed to the upper end of the fixed cylinder 1402 , and a sealing plate is fixed to the upper end of the bellows 1421 , which is fixedly connected to the steel wire 1306 ; the bellows 1421 can seal the perforation 1403 while the steel wire 1306 rises and falls, to prevent the liquid inside the tank body 1 from entering the fixed cylinder 1402 .

[0051] Before use, the operator can rotate the rotating member 1417 to drive the threaded sleeve 1416 to rotate, and then adjust the height of the threaded tube 1420 and the slider 1408. During the use of the reactor for drug manufacturing, the driving motor 605 is started to drive the connecting frame 603 and the rotating plate 601 to rotate, and then drive the rotating tube 2 to rotate.

The rotating tube 2 rotates, and then drives the lifting block 7 and the two rotating arms 10 to rotate, achieving a stirring effect. After the reaction is completed, the rotating motor 1304 rotates to drive the winding roller 1305 to rotate, and the steel wire 1306 is wound up. The steel wire 1306 drives the lifting cylinder 14 01 moves up, the lifting cylinder 1401 drives the lifting block 7 and the parts connected to the lifting block 7 to move up synchronously, and at this time, under the action of gravity of the lifting block 7 and its connected parts, the spring 1404 is compressed to the shortest state, and as the lifting block 7 moves upward, the fixed column 1405 is inserted into the locking cylinder 1410 at a position, and at this time, the locking tongue 1413 shrinks toward the through hole 1411 under the pressure of the conical head 1406, and after the conical head 1406 rises above the locking tongue 1413, under the repulsive force of the first magnetic block 1414 and the second magnetic block 1415, the locking tongue 1413 extends out, and at this time, the upper surface of the locking tongue 1413 abuts against the lower surface of the conical head 1406, and the lifting block 7 will be restricted from moving downward, and the liquid level in the tank body 1 is at the oblique scraping strip 12, and then release the steel wire 1306, the spring 1404 will squeeze the lifting cylinder 1401 downward, release the seal of the connection between the through hole 9 and the groove 11, and then the driving motor 605 will drive the rotating tube 2 to rotate slowly. At this time, the floating foam is affected by the oblique scraper bar 12 and the rotary arm 10, enters the through hole 9 along the groove 11, and is discharged after passing through the lifting tube 15 downward along the through hole 9. The steps for removing the floating foam are simple and easy to operate. After skimming the floating foam, the steel wire 1306 is wound up by rotating the motor 1304, so that the spring 1404 is compressed to the shortest again, and the lifting cylinder 1401 blocks the connection between the through hole 9 and the groove 11 again, and then the steel wire 1306 is continuously wound up to drive the lifting block 7 upward. The lifting block 7 moves upward, and the locking tongue 1413 shrinks into the through hole 1411 under the extrusion of the inverted cone ring 1407. After the inverted cone ring 1407 rises to the top of the locking tongue 1413, the locking tongue 1413 extends out under the repulsive force of the first magnetic block 1414 and the second magnetic block 1415, and then releases the steel wire 1306. At this time, the lifting block 7 descends under the action of gravity. At this time, the inverted cone ring 1407 will not move downward with the lifting block 7 under the action of the locking tongue 1413. As the fixing column 1405 descends, the inverted cone ring 1407 fits with the conical head 1406 and is squeezed downward by the conical head 1406. At this time, the locking tongue 1413 shrinks into the through hole 1411 again under the extrusion of the lower surface of the inverted cone ring 1407.At this time, the locking tongue 1413 can pass over the inverted cone ring 1407 and the cone head 1406, and the restricting effect on the lifting block 7 can be released. The steel wire 1306 is further released, and the lifting block 7 can move downward.
