Abstract
Description
Technical Field
[0001] This application relates to the field of chemical reaction equipment technology, and in particular to an openable clamp-type oil bath heating reaction device. Background Technology
[0002] Oil bath heating is widely used in chemical laboratories, typically involving placing the reaction vessel directly in the oil bath. This open heating method poses certain safety risks; some oils may produce harmful gases or fumes at high temperatures, endangering the health of laboratory personnel and polluting the environment. Current closed oil bath heating systems rely on heat conduction between the heating device and the reaction vessel, but the presence of air between them results in low heating efficiency and significant heat loss. Therefore, research on oil bath heating reaction devices is necessary.
[0003] In the prior art, Chinese patent CN216879292U discloses a laboratory reaction vessel oil bath heating mechanism, including a vessel body and a vessel cover. A guide plate is formed on the outer side of the vessel body, spirally wound around the circumference of the vessel body. An oil heating sleeve is sleeved on the outer side of the guide plate. The inner side wall of the oil heating sleeve is in close contact with the outer edge of the guide plate. An oil heating spiral cavity is formed between the guide plate and the oil heating sleeve. An oil inlet pipe joint communicating with the oil heating spiral cavity is provided on the side wall of the oil heating sleeve away from the vessel cover. An oil outlet pipe joint communicating with the oil heating spiral cavity is provided on the side wall of the oil heating sleeve near the vessel cover.
[0004] However, the reactor and heating jacket of the above-mentioned prior art are an integrated structure, which makes it difficult to disassemble and assemble the reactor, resulting in poor experimental flexibility and automation. If the reactor is to be disassembled and assembled, the contact area between the heat source and the reactor cannot be guaranteed, leading to a reduction in experimental reaction efficiency. Utility Model Content
[0005] This application provides an openable clamp-type oil bath heating reaction device to solve the problems of existing oil bath heating reaction devices, which are difficult to disassemble and assemble, resulting in poor experimental flexibility and automation; if the disassembly and assembly of the reaction vessel is to be realized, the contact area between the heat source and the reaction vessel cannot be guaranteed, leading to a reduction in experimental reaction efficiency.
[0006] On the one hand, this application provides an opening and closing clamp-type oil bath heating reaction device, including: a reaction vessel, a heating jacket, an opening and closing clamp motor, a crank connecting rod mechanism, and a clamp arm.
[0007] The opening and closing clamp motor is connected to the clamp arm via the crank-connecting rod mechanism. The heating sleeve is an openable and closable structure. The outer wall of the heating sleeve is connected to the inner wall of the clamp arm. The outer wall of the reactor is detachably connected to the inner wall of the heating sleeve.
[0008] The opening and closing clamp motor is used to control the opening or closing of the clamp arm through the crank-connecting rod mechanism.
[0009] The clamping arm is used to open or close the heating sleeve.
[0010] When the heating jacket is closed, the outer wall of the reactor is in close contact with the inner wall of the heating jacket without any gap.
[0011] In one possible implementation, the heating jacket comprises, from the inner wall to the outer wall, a flow channel cavity structure and a heat insulation layer.
[0012] The inner wall of the heating jacket is made of metal, and the outer wall is made of a heat insulation cover.
[0013] In one possible implementation, the insulation layer is made of aerogel.
[0014] In one possible implementation, the heat insulation cover is made of bakelite.
[0015] In one possible implementation, the flow channel cavity structure includes: a heat source inlet, a heat source flow channel, a heat source outlet, a right-turning axis flow channel, a left-turning axis flow channel, a first cavity, a second cavity, a third cavity, a fourth cavity, a fifth cavity, and a sixth cavity.
[0016] The heat source flow channel sequentially connects the heat source inlet, the first cavity, the second cavity, the right-turning axis flow channel, the third cavity, the fourth cavity, the left-turning axis flow channel, the fifth cavity, the sixth cavity, and the heat source outlet.
[0017] In one possible implementation, the opening and closing clamp-type oil bath heating reaction device further includes: a vision module that passes through the heating jacket, and a viewing window is provided on the reactor corresponding to the position of the vision module.
[0018] The vision module is used to monitor the internal reaction conditions of the reactor.
[0019] In one possible implementation, the vision module includes: a camera, a rear section of a camera heat shield, a heat-insulating lens, and a front section of a camera heat shield.
[0020] The front section of the camera heat shield contacts the viewing window of the reactor. The front section and the rear section of the camera heat shield together form a camera heat shield cavity. The camera is fixedly installed inside the camera heat shield cavity, and the heat-insulating lens is fixedly installed on the side of the camera facing the reactor.
[0021] In one possible implementation, the rear section of the camera heat shield located outside the heating jacket is provided with an inert gas replacement inlet and an inert gas replacement outlet.
[0022] The opening and closing clamp-type oil bath heating reaction device of this application has the following advantages:
[0023] By setting up an openable and closable heating jacket, along with an opening and closing clamping motor, crank connecting rod mechanism, and clamping arm, the outer wall of the reactor and the inner wall of the heating jacket are in close contact without gap when the heating jacket is closed. This increases the contact area between the heat source and the reactor, shortens the heat conduction path, and reduces heat loss. It also enables convenient disassembly and assembly of the reactor without reducing the experimental reaction efficiency, thus improving the flexibility and automation of the experiment.
[0024] The proposed heating jacket consists of, from the inner wall to the outer wall, a flow channel cavity structure and an insulation layer. The insulation layer effectively reduces heat source loss and further improves the experimental reaction efficiency.
[0025] The proposed vision module includes: a camera, a rear section of the camera heat shield, a heat-insulating lens, and a front section of the camera heat shield. The rear section of the camera heat shield, the heat-insulating lens, and the front section of the camera heat shield provide heat insulation protection for the camera to prevent damage from high temperatures.
[0026] The proposed camera heat shield has an inert gas replacement inlet and an inert gas replacement outlet located on the outer side of the heating jacket. This allows for the replacement of the camera heat shield cavity with inert gas, circulating the internal hot gas to the outside of the device. This effectively helps cool the camera and also prevents condensation and frost from affecting visual observation and judgment during the cooling process. Attached Figure Description

Detailed Implementation
[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0036] like Figure 1 As shown in the figure, this application provides an opening and closing clamp-type oil bath heating reaction device, including: a reaction vessel 1, a heating jacket 2, an opening and closing clamp motor 4, a crank connecting rod mechanism 5, and a clamp arm 6.
[0037] The opening and closing clamping motor 4 is connected to the clamping arm 6 via the crank connecting rod mechanism 5. The heating sleeve 2 is an openable and closable structure. The outer wall of the heating sleeve 2 is connected to the inner wall of the clamping arm 6. The outer wall of the reactor 1 is detachably connected to the inner wall of the heating sleeve 2.
[0038] The opening and closing clamping motor 4 is used to control the opening or closing of the clamping arm 6 through the crank-connecting rod mechanism 5.
[0039] The clamping arm 6 is used to drive the heating sleeve 2 to open or close.
[0040] When the heating sleeve 2 is closed, the outer wall of the reactor 1 is in close contact with the inner wall of the heating sleeve 2 without any gap.
[0041] Specifically, in this embodiment, the opening and closing clamping motor 4 is electrically connected to a PLC controller.
[0042] In one possible embodiment, the clamping arm 6 is provided with a limit switch.
[0043] Specifically, in this embodiment, the operating principle of the opening and closing clamp-type oil bath heating reaction device is as follows: In the initial state, the reaction vessel 1 is not assembled, and the heating jacket 2 is in a closed state; the PLC controller sends a control command to the opening and closing clamp motor 4, causing the opening and closing clamp motor 4 to rotate forward. The opening and closing clamp motor 4 controls the clamp arm 6 to open through the crank connecting rod mechanism 5. The clamp arm 6 drives the heating jacket 2 to open. When the limit switch senses the opening to the correct position, the PLC controller controls the opening and closing clamp motor 4 to stop; the reaction vessel 1 is placed by a robotic arm or other means. At the center of the heating jacket 2, the PLC controller sends a control command to the opening and closing clamping motor 4, causing the opening and closing clamping motor 4 to reverse. The opening and closing clamping motor 4 controls the clamping arm 6 to close through the crank connecting rod mechanism 5. The clamping arm 6 drives the heating jacket 2 to close. When the limit switch senses the closure and is in place, the PLC controller controls the opening and closing clamping motor 4 to stop. At this time, the outer wall of the reactor 1 is in close contact with the inner wall of the heating jacket 2 without gaps, and the heat source is introduced into the heating jacket 2. The heat source can directly transfer heat to the reactor 1 through the inner wall of the heating jacket 2, improving the heating efficiency.
[0044] Specifically, in this embodiment, the heat source is heat transfer oil.
[0045] like Figure 2 The image shows the heating jacket in the closed state, as shown. Figure 3 The image shows the heating jacket in the open position.
[0046] like Figure 4 As shown, exemplarily, the heating sleeve 2 includes, from the inner wall to the outer wall, the following components in sequence: a flow channel cavity structure and a heat insulation layer 206.
[0047] The inner wall of the heating jacket 2 is made of metal, and the outer wall is made of a heat insulation cover 207.
[0048] For example, the insulation layer 206 is made of aerogel.
[0049] Specifically, in this embodiment, the thickness of the insulation layer 206 is 40mm.
[0050] For example, the heat insulation cover 207 is made of bakelite.
[0051] Specifically, in this embodiment, the outer wall of the heating jacket 2 includes a side outer wall, a top outer wall, and a bottom outer wall, all of which are made of heat insulation cover shell 207. Through thermal simulation, when the internal temperature of the reactor 1 is 220°C, the temperature of the heat insulation cover shell 207 is below 45°C, effectively preventing heat loss from the heat source, reducing the shell temperature of the heating device, and preventing accidental burns.
[0052] For example, the flow channel cavity structure includes: heat source inlet 201, heat source flow channel 202, heat source outlet 203, right-turn axis flow channel 204, left-turn axis flow channel 205, first cavity 211, second cavity 212, third cavity 213, fourth cavity 214, fifth cavity 215, and sixth cavity 216.
[0053] The heat source flow channel 202 sequentially connects the heat source inlet 201, the first cavity 211, the second cavity 212, the right-turn axis flow channel 204, the third cavity 213, the fourth cavity 214, the left-turn axis flow channel 205, the fifth cavity 215, the sixth cavity 216, and the heat source outlet 203.
[0054] Specifically, in this embodiment, both the heat source inlet 201 and the heat source outlet 203 pass through the insulation layer 206 and the heat insulation cover shell 207.
[0055] In this embodiment, the heat transfer oil flows in from the heat source inlet 201, flows into the second cavity 212 through the lower flow channel of the first cavity 211, and after the second cavity 212 is filled, the heat transfer oil flows into the right-hand shaft flow channel 204 through the upper flow channel of the second cavity 212, and flows into the third cavity 213 through the lower flow channel of the right-hand shaft flow channel 204. After the third cavity 213 is filled, the heat transfer oil flows into the fourth cavity 214 through the upper flow channel of the third cavity 213, and flows into the left-hand shaft flow channel 205 through the lower flow channel of the fourth cavity 214. After the left-hand shaft flow channel 205 is filled, the heat transfer oil flows into the sixth cavity 216 through the upper flow channel of the left-hand shaft flow channel 205, and flows into the sixth cavity 216 through the lower flow channel of the sixth cavity 216, and finally flows out from the heat source outlet 203.
[0056] like Figure 5 As shown, exemplarily, the opening and closing clamp-type oil bath heating reaction device further includes: a vision module 3, which passes through the heating sleeve 2, and the reaction vessel 1 is provided with a viewing window corresponding to the position of the vision module 3.
[0057] The vision module 3 is used to monitor the internal reaction of the reactor 1.
[0058] For example, the vision module 3 includes: a camera 301, a rear section of the camera heat shield 302, a heat shield lens 303, and a front section of the camera heat shield 304.
[0059] The front section 304 of the camera heat shield is in contact with the viewing window of the reactor 1. The front section 304 and the rear section 302 of the camera heat shield form a camera heat shield cavity. The camera 301 is fixedly installed inside the camera heat shield cavity. The heat shield lens 303 is fixedly installed on the side of the camera 301 facing the reactor 1.
[0060] For example, the rear section 302 of the camera heat shield located on the outside of the heating sleeve 2 is provided with an inert gas replacement inlet 305 and an inert gas replacement outlet 306.
[0061] Specifically, the inert gas inlet 305 and the inert gas outlet 306 can replace the inside of the camera heat shield cavity with inert gas, circulating the internal hot gas to the outside of the device, which can effectively help cool down the camera 301.
[0062] This embodiment of the application, by setting up a heating sleeve 2 with an openable and closable structure, in conjunction with an opening and closing clamping motor 4, a crank connecting rod mechanism 5, and a clamping arm 6, ensures that when the heating sleeve 2 is closed, the outer wall of the reactor 1 and the inner wall of the heating sleeve 2 are in close contact without gaps. This increases the contact area between the heat source and the reactor 1, shortens the heat conduction path, and reduces heat loss. Without reducing the experimental reaction efficiency, it achieves convenient disassembly and assembly of the reactor 1, improving experimental flexibility and automation.
[0063] The proposed heating jacket 2 includes, from the inner wall to the outer wall, a flow channel cavity structure and a heat insulation layer 206. The heat insulation layer 206 effectively reduces heat source loss and further improves the experimental reaction efficiency.
[0064] The proposed vision module 3 includes: camera 301, rear section of camera heat shield 302, heat shield lens 303, and front section of camera heat shield 304. The rear section of camera heat shield 302, heat shield lens 303, and front section of camera heat shield 304 provide heat insulation protection for camera 301 to prevent damage to camera 301 due to high reaction temperature.
[0065] The rear section 302 of the proposed camera heat shield, located on the outer side of the heating jacket 2, is equipped with an inert gas replacement inlet 305 and an inert gas replacement outlet 306. This allows for inert gas replacement inside the camera heat shield cavity, circulating the internal hot gas to the outside of the device. This effectively helps to cool down the camera 301 and also prevents condensation and frost formation during the cooling process from affecting visual observation and judgment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
[0067] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
