[0010] Furthermore, the stirring tube is provided with an annular cavity along the outer circumference, the second interlayer is connected to the annular cavity through a first pipeline, and the outer tube is connected to the annular cavity through a second pipeline, so that the heat transfer fluid in the second interlayer can flow through the annular cavity to the inner side of the outer tube, thereby driving the inner tube to extend and move, and an elastic member is arranged between the inner tube and the outer tube.

[0012] Furthermore, a guide plate is spirally distributed on the inner side of the first interlayer along the height direction, and one end of the guide plate faces the liquid inlet and the other end faces the liquid outlet, so that the heat-conducting liquid in the first interlayer flows in a spiral along the guide plate; an adjustment groove is provided on the bottom side of the kettle body along the circumferential direction, and one end of the guide plate facing the liquid outlet is extended in the adjustment groove and connected to a lifting ring, and the lifting ring is lifted and lowered in the adjustment groove by a telescopic rod, so that when the lifting ring is lifted and lowered relative to the adjustment groove, the number of spiral turns of the guide plate in the first interlayer changes.

DETAILED DESCRIPTION

Obviously, the described embodiments 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 belong to the scope of protection of the present invention.

Therefore, the above terms should not be understood as limiting the present invention.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] like Figure 1-Figure 9The present invention provides an automatic temperature-controlled reactor, comprising a reactor body 1, a reaction chamber 2 opened inside the reactor body 1, a premixing assembly connected to the top of the inner side of the reactor body 1, a stirring tube 3 rotatably arranged inside the reactor body 1, and a discharge port 4 arranged at the bottom of the reaction chamber 2, wherein a feed port 5 is opened at one end of the stirring tube 3, and a plurality of stirring rods 6 are arranged circumferentially at the other end, the premixing assembly comprises a premixing chamber 7 sleeved on the outer periphery of the stirring tube 3, a premixing chamber 8 opened inside the premixing chamber 7, and a plurality of premixing discharge ports 9 opened at the bottom of the premixing chamber 7 and connected to the premixing chamber 8, the plurality of premixing discharge ports 9 are arranged at intervals along the circumference of the stirring tube 3, and the premixing chamber 8 is distributed along the outer periphery of the stirring tube 3, so that part of the material enters the reaction chamber 2 from the feed port 5, and another part of the material enters the premixing chamber 8 for premixing before entering the reaction chamber 2.

[0030] The premixing assembly and the stirring tube are placed in the reaction chamber, and then part of the raw materials are directly transported to the reaction chamber through the inside of the stirring tube through the feed port, and at the same time, another part of the raw materials that are not easy to disperse and mix are first placed in the premixing chamber, and the part of the raw materials are premixed through the premixing chamber. After the premixing is completed, the premixed mixture is transported to the reaction chamber through the premixing discharge port to ensure sufficient mixing reaction between the raw materials. Since the plurality of premixing discharge ports are arranged at intervals along the circumference of the stirring tube, the mixture in the premixing chamber can be dispersed and uniformly introduced into the reaction chamber, thereby further improving the reaction effect between the various raw materials.

[0031] Among them, valves are arranged at the discharge port and the premix discharge port.

[0032] In one embodiment of the present solution, the outer periphery of the premixing chamber is threadedly matched with the inner wall of the reaction chamber, so that the premixing chamber and the reaction chamber are detachably connected, and the premixing chamber can be conveniently disassembled and cleaned.

[0033] Preferably, a first interlayer 10 is provided on the side wall and the bottom of the kettle body 1, and a liquid inlet 11 connected to the first interlayer 10 is provided on the top side of the kettle body 1, and a liquid outlet 12 connected to the first interlayer 10 is provided on the bottom side of the kettle body 1. The liquid inlet 11 transfers the heat-conducting liquid to the first interlayer 10, and the heat-conducting liquid is outputted from the liquid outlet 12, so that the heat-conducting liquid circulates in the first interlayer 10.

[0034] Specifically, the heat-conducting liquid is transmitted to the first interlayer through the liquid inlet, so that the heat-conducting liquid controls the temperature of the reaction chamber. Since the heat-conducting liquid is simultaneously transported outward at the liquid outlet, the heat-conducting liquid in the first interlayer is in a circulating flow state, thereby allowing the heat-conducting liquid to continuously and stably heat and control the temperature inside the reactor.

[0035] In one embodiment of the present scheme, the liquid inlet and the liquid outlet are connected to an external thermal liquid supply device, and the supply device is equipped with a heating component to ensure that the temperature of the thermal liquid is sufficient to heat the raw materials inside the reaction chamber. Due to the continuous and circulating flow of the thermal liquid, the heating component at the supply device can stably control the temperature at the reaction chamber to improve the control efficiency of the temperature required for different reaction stages.

[0036] Preferably, a second interlayer 13 is provided on the side wall and the bottom of the premixing chamber 7, and a liquid inlet 14 is provided at the top of the second interlayer 13, and the liquid inlet 14 is used to transmit or extract the heat-conducting liquid to the second interlayer 13, so that the second interlayer 13 can be switched between a heat-conducting state and a heat-insulating state.

[0037] Specifically, through the provision of the second interlayer, the heat-conducting liquid can enter the second interlayer through the liquid inlet, and conduct the heat in the first interlayer to the second interlayer through the heat-conducting liquid, and then the premixing chamber is heated and controlled by the heat-conducting liquid in the second interlayer, so that the temperature in the premixing chamber is basically consistent with that in the reaction chamber, thereby ensuring the reaction temperature in the premixing chamber. Since some raw materials have the problem of premature chemical denaturation due to high temperature, the present scheme can also extract the heat-conducting liquid in the second interlayer through the liquid inlet, so that the interior of the second interlayer is in a vacuum-like state, and then the second interlayer can insulate the premixing chamber to avoid premature chemical denaturation of the raw materials in the premixing chamber.

[0038] It is worth mentioning that after the heat-conducting liquid enters the second interlayer, when the heat-conducting liquid is extracted again through the liquid inlet, it is difficult for the heat-conducting liquid to be completely extracted from the second interlayer. Therefore, only a quasi-vacuum environment can be achieved in the second interlayer, but the residual heat-conducting liquid basically gathers at the bottom of the second interlayer. Therefore, the heat-conducting effect produced by the heat-conducting liquid actually remaining in the second interlayer is poor, and it is difficult to raise the temperature in the premixing chamber to the same temperature as the reaction chamber, thereby ensuring that the raw materials in the premixing chamber will not be denatured prematurely.

[0039] The heat transfer liquid in the second interlayer is only used to conduct heat in the first interlayer, so the heat transfer liquid in the second interlayer does not need to circulate, and only a liquid inlet is opened in the second interlayer to ensure the switching of the heat conduction and insulation states of the second interlayer.

[0040] In one embodiment of the present scheme, an end of the liquid inlet close to the inside of the second interlayer is connected to a liquid inlet tube, and the liquid inlet is extended to the bottom side of the second interlayer through the liquid inlet tube, so that when the liquid inlet draws out the thermal liquid in the second interlayer, the amount of thermal liquid drawn out can be increased through the liquid inlet tube, thereby further improving the thermal insulation effect of the second interlayer.

[0041] Preferably, the stirring tube 3 is located on one side of the premixing chamber 7 and is provided with a plurality of adsorption blocks 15 at intervals along the circumferential direction, a rotating ring 16 is provided inside the premixing chamber 8, a plurality of premixing rods 17 are provided at intervals on the outer circumference of the rotating ring 16, and the adsorption blocks 15 and the rotating ring 16 are in adsorption cooperation, so that when the stirring tube 3 is in a rotating state, the rotating ring 16 rotates with the stirring tube 3.

[0042] Specifically, when the raw materials inside the reaction chamber are stirred and mixed, the stirring tube needs to rotate to drive several stirring rods to rotate and stir. At this time, several adsorption blocks can synchronously drive the rotating ring to rotate, so that the rotating ring synchronously drives several premixing rods to rotate. At this time, the stirring tube can be used to simultaneously cause several stirring rods and several premixing rods to perform stirring processing, thereby making it possible to uniformly mix the reaction chamber and the premixing chamber at the same time without the need for additional driving parts.

[0043] Among them, a number of magnets are arranged at intervals on the inner circle of the rotating ring, the adsorption blocks are made of magnets, and the several magnets and the several adsorption blocks are arranged in a one-to-one correspondence, so that when the rotating ring is sleeved on the outer periphery of the stirring tube, it can be positioned by the adsorption of the magnets and the adsorption blocks, thereby ensuring the stable driving of the stirring tube on the rotating ring.

[0044] Preferably, a scraper 18 is rotatably provided at the side wall of the reaction chamber 2, wherein a stirring rod 6 includes an outer tube 19 and an inner tube 20, the inner tube 20 and the outer tube 19 are movably matched, and a shift block 21 is provided on the side of the scraper 18 close to the inner tube 20, so that the inner tube 20 and the shift block 21 are matched.

[0045] Specifically, since some of the finished products contain colloids or have high viscosity, some of the products will adhere to the side walls of the reaction chamber. At this time, the inner tube is extended relative to the outer tube, so that when the inner tube rotates with the stirring tube to the shift block, the shift block can be moved by the inner tube pushing the shift block, and then the shift block drives the scraper to rotate and scrape the material, so as to scrape off the colloids, sticky substances, etc. on the side walls, and then the colloids and sticky substances are discharged from the discharge port together with the finished products.

[0046] The scraper is arranged at an angle, so that when the scraper rotates to scrape the material, the material on the side wall can be scraped off at an angle, thereby improving the scraping effect.

[0047] In one embodiment of the present solution, the shift block is arranged in a semi-annular structure, and the inner diameter of the shift block matches the outer diameter of the inner tube, so that the inner tube can be matched with the shift block for pushing.

[0048] Preferably, the stirring tube 3 is provided with an annular cavity 22 along the outer circumference, the second interlayer 13 is connected to the annular cavity 22 through the first pipeline 23, and the outer tube 19 is connected to the annular cavity 22 through the second pipeline 24, so that the heat transfer fluid in the second interlayer 13 can flow to the inner side of the outer tube 19 through the annular cavity 22, thereby driving the inner tube 20 to extend and move, and an elastic member 25 is arranged between the inner tube 20 and the outer tube 19.

[0049] Specifically, due to the setting of the annular cavity, the heat-conducting liquid in the second interlayer can be transmitted to the annular cavity through the first pipeline to ensure that the heat-conducting liquid can still be stably transmitted to the annular cavity during the rotation of the stirring tube. At the same time, when the inner tube needs to be extended, the second interlayer is continuously supplied with liquid through the liquid inlet, so that the heat-conducting liquid in the second interlayer continues to be supplied to the annular cavity. At this time, the outer tube is replenished with heat-conducting liquid through the second pipeline. With the continuous supply of the liquid inlet, the inner tube is pushed by the heat-conducting liquid, and then the inner tube is extended and moved along the outer tube, so that the inner tube can push the scraper for scraping. After the scraping is completed, the heat-conducting liquid is extracted from the liquid inlet, so that the inner tube is reset and contracted under the elastic force of the elastic member, thereby ensuring that the inner tube maintains a normal stirring effect.

[0050] Wherein, the elastic member adopts a spring structure.

[0051] Preferably, a limiting groove 26 is circumferentially provided on one side of the premixing chamber 7 close to the reaction chamber 2 , and a limiting flange 27 is provided at the end of the scraper 18 , and the limiting flange 27 matches the limiting groove 26 , so that the scraper 18 can rotate along the limiting groove 26 .

[0052] Specifically, by matching the limiting groove with the limiting flange, the scraper can only move along the limiting groove when pushed by the inner tube, thereby improving the accuracy of the scraper's rotation path and avoiding the problem of unstable rotation of the scraper due to excessive interference after the scraper contacts the colloid.

[0053] At the same time, since the limiting groove is connected to the premixing chamber, the scraper can be taken out synchronously after the premixing chamber is disassembled from the reaction chamber, so that the scraper can be cleaned conveniently, thereby improving the stability of subsequent scraping processing.

[0054] Preferably, a guide plate 28 is spirally distributed on the inner side of the first interlayer 10 along the height direction, and one end of the guide plate 28 faces the liquid inlet 11, and the other end faces the liquid outlet 12, so that the heat-conducting liquid in the first interlayer 10 flows in a spiral along the guide plate 28; an adjustment groove 36 is provided on the bottom side of the kettle body 1 along the circumferential direction, and one end of the guide plate 28 facing the liquid outlet 12 is extended and arranged in the adjustment groove 36 and is connected to a lifting ring 37, and the lifting ring 37 is lifted and lowered in the adjustment groove 36 by a telescopic rod 38, so that when the lifting ring 37 is lifted and lowered relative to the adjustment groove 36, the number of spiral turns of the guide plate 28 in the first interlayer 10 changes.

[0055] Specifically, after the heat transfer liquid is transported to the first interlayer at the liquid inlet, the heat transfer liquid flows along the guide plate and finally flows to the liquid outlet to be discharged from the first interlayer. During this process, the heat transfer liquid can circulate along the first interlayer in a spiral shape, thereby improving the heat transfer effect of the heat transfer liquid on the reaction chamber.

[0056] At the same time, through the setting of the lifting ring, when the telescopic rod is extended to push the lifting ring to rise, the lifting ring will squeeze the guide plate upward, so that the number of spiral turns of the guide plate in the first interlayer increases, thereby increasing the circulation flow path of the heat transfer liquid, slowing down the heat conduction efficiency of the heat transfer liquid to the reaction chamber, so as to facilitate constant temperature treatment of the reaction chamber; and when the lifting ring is lowered by the contraction of the telescopic rod, the guide plate is pulled by the lifting ring, so that part of the guide plate enters the adjusting groove, thereby reducing the number of spiral turns of the guide plate in the first interlayer, so that the circulation flow path of the heat transfer liquid becomes shorter, and the heat conduction efficiency of the heat transfer liquid to the reaction chamber is increased, so that the first interlayer can quickly heat up or cool down the reaction chamber, ensuring the temperature treatment effect in the initial and final stages of the reaction.

[0057] Among them, the deflector is made of spring steel structure, and the telescopic rod is a hydraulic rod.

[0058] Preferably, a cover 29 is provided at the opening position on the top of the kettle body 1, and a driving wheel 30 is rotatably installed on one side of the cover 29 close to the premixing chamber 8, and a plurality of gear teeth 31 are arranged circumferentially at the end of the stirring tube 3 so that the gear teeth 31 match the driving wheel 30.

[0059] Specifically, by matching the driving wheel with a plurality of gear teeth, when the driving wheel rotates, the gear teeth can drive the stirring tube to rotate, thereby ensuring the stirring effect in the reaction chamber and the premixing chamber.

[0060] In one embodiment of the present solution, a motor is provided at the cover body, and the motor is used to control the rotation of the driving wheel.

[0061] Preferably, the cover body 29 is provided with a main material port 32 and a secondary material port 33, the main material port 32 corresponds to the feed port 5, and the secondary material port 33 is arranged toward the premixing chamber 8. The cover body 29 is also provided with a liquid inlet groove 34, and the liquid inlet groove 34 corresponds to the liquid inlet 14, and a positioning groove 35 is provided on the side of the cover body 29, and the liquid inlet 11 is snapped into the positioning groove 35.

[0062] Specifically, the reaction chamber and the premixing chamber are fed respectively through the main material port and the auxiliary material port to avoid confusion between the raw materials in the premixing chamber and the reaction chamber. At the same time, the liquid introduction groove is matched with the liquid introduction port to improve the transmission and extraction effect of the liquid introduction port at the second interlayer.

[0063] It is worth mentioning that since a positioning groove is provided on the side of the cover body, when the cover body is installed on the kettle body, the liquid inlet is snapped into the positioning groove, so that the cover position of the cover body is circumferentially positioned. At this time, the auxiliary material port, liquid inlet groove and other structures can be accurately positioned synchronously to ensure the stable transmission of heat transfer liquid, raw materials, etc.

[0064] In an embodiment of the present solution, the cover body is connected to the kettle body by means of a snap or the like, and a plurality of supporting legs are arranged on the sides of the bottom of the kettle body.

[0065] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
