DETAILED DESCRIPTION

[0038] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0039] like Figures 1 to 4 As shown, a modular replaceable reaction device comprises:

[0040] The main frame 1 has an opening on one side;

[0041] The mobile frame 2 can be freely pushed into and out of the main frame 1 from the opening;

[0042] A stirrer 3 is mounted on the main frame 1 and is provided with an output shaft 31;

[0043] The reaction kettle 4 is mounted on the mobile frame 2 and is provided with a stirring shaft 41 ; wherein the stirring shaft 41 is connected to the output shaft 31 via a quick-release structure.

[0044] In the present application, the reaction device adopts a modular design, and the main frame 1 is equipped with an agitator 3 and various functional modules, and is usually fixed in a preset position. The mobile frame 2 carries the reactor 4 and is pushed into the main frame 1 to form a reaction device. The agitator 3 drives the agitator shaft 41 to rotate through its output shaft 31 to achieve the stirring of the materials in the reactor 4. The reactor 4 is configured with multiple sets according to different specifications or experimental batches, and each set of the reactor 4 is separately installed on a mobile frame 2. Multiple mobile frames 2 share a main frame 1, and multiple sets of reactors 4 share an agitator 3. When replacing the reactor 4, the agitator shaft 41 and the output shaft 31 are disassembled through the quick-release structure, and the old mobile frame 2 carrying the reactor 4 is pushed out; then the new mobile frame 2 carrying the reactor 4 is pushed in, and the agitator shaft 41 and the output shaft 31 are reinstalled through the quick-release structure to complete the replacement. Since multiple mobile frames 2 carrying different reactors 4 can be quickly combined with the main frame 1, the steps of manual disassembly and assembly are simplified, and the time of manual disassembly and assembly is reduced, thereby solving the problem of inconvenience in replacing the reactor 4 of the reaction device and achieving the effect of quick replacement.

[0045] In some embodiments, the stirrer 3 is vertically mounted on the top of the main frame 1, and its output shaft 31 is vertically downward. The reactor 4 is centrally mounted inside the mobile frame 2, and its stirring shaft 41 is vertically upward. The upper end of the stirring shaft 41 extends out of the reactor 4, and a stirring paddle is installed at the lower end of the stirring shaft 41 and is located inside the reactor 4. After the mobile frame 2 is pushed into the preset position in the main frame 1, the reactor 4 is located below the stirrer 3, and the axis of the stirring shaft 41 is aligned with the axis of the output shaft 31.

[0046] In some embodiments, the volumes of the multiple reaction kettles 4 are different, with the lowest reaction volume being 1 L and the highest reaction volume being 10 L. The reaction kettles 4 are made of high-quality borosilicate glass or PTFE.

[0047] like Figure 2 As shown, specifically, the quick-release structure includes:

[0048] A self-calibrating connector 32 is mounted at the end of the output shaft 31 and has a flexible centering function;

[0049] A connecting seat 33 is sleeved on the end of the self-calibration connecting head 32 and the end of the stirring shaft 41;

[0050] The adjustable snap ring 34 is sleeved on the connecting seat 33 and can lock the connecting seat 33 .

[0051] In the present application, the quick-release structure is located on the output shaft 31, the top of the stirring shaft 41 is inserted into the connecting seat 33, and after the adjustable clamping ring 34 locks the connecting seat 33, the power of the output shaft 31 is transmitted to the stirring shaft 41 through the self-calibration connector 32 and the connecting seat 33. The flexible centering function of the self-calibration connector 32 allows a small amount of axial offset between the output shaft 31 and the stirring shaft 41, so that even when the reactor 4 is replaced, after the mobile frame 2 is pushed into the main frame 1, a small position deviation occurs, which does not affect the coaxial connection between the output shaft 31 and the stirring shaft 41.

[0052] Furthermore, a first fastener 331 and a semi-ring structure 332 are respectively provided at both ends of the connecting seat 33. The first fastener 331 is used to fasten the connecting seat 33 and the self-calibration connecting head 32, and the semi-ring structure 332 is used to clamp the connecting seat 33 and the stirring shaft 41. The adjustable clamping ring 34 is provided with a second fastener 341, and the second fastener 341 is used to lock the semi-ring structure 332.

[0053] In the present application, after the first fastener 331 is tightened, the connection seat 33 is relatively fixed to the self-calibration connector 32. The adjustable snap ring 34 is an open ring structure, and after the second fastener 341 is tightened, the inner diameter of the adjustable snap ring 34 can be reduced, thereby tightening the semi-ring structure 332 of the connection seat 33, so that the connection seat 33 and the stirring shaft 41 are relatively fixed, and finally the power transmission from the output shaft 31 to the stirring shaft 41 is realized.

[0054] In some embodiments, in the quick-release structure, the self-calibration connector 32 is a universal joint. The connecting seat 33 is a hollow cylindrical structure, with a threaded hole corresponding to the first fastener 331 on the upper part, and a pair of semi-ring structures 332 formed by an incision on the lower part. The first fastener 331 and the second fastener 341 are both screws. The speed control range of the output shaft 31 is 20-500rpm. When the quick-release structure is disassembled, loosen the first fastener 331 and the second fastener 341, push the adjustable retaining ring 34 and the connecting seat 33 upward, so that the connecting seat 33 is separated from the top of the stirring shaft 41, and the disassembly can be completed. When the quick-release structure is installed, align the axis of the stirring shaft 41 with the axis of the output shaft 31, push the adjustable retaining ring 34 and the connecting seat 33 downward, insert the top of the stirring shaft 41 into the semi-ring structure 332, tighten the first fastener 331 and the second fastener 341, and the installation can be completed. It can be seen that the operation method of the quick-release structure is simple and fast.

[0055] like Figure 3 As shown, specifically, the reaction kettle 4 includes a kettle body 42 and a kettle cover 43; the top of the kettle cover 43 is provided with:

[0056] Pipeline connector 44, used for inputting materials involved in the reaction;

[0057] A sensor connector 45 is used to install a sensor for detecting the reaction process in the reactor 4;

[0058] The condenser 46 is used to recover the low boiling point solvent in the reaction kettle 4 .

[0059] Specifically, the bottom of the kettle body 42 is provided with:

[0060] The discharge pipe 47 is located at the lowest point of the reactor body 42 and is used to discharge materials after the reaction in the reactor 4 stops unexpectedly;

[0061] The discharge connector 48 is located at one side of the discharge pipe 47 and is used to discharge materials after the reaction kettle 4 finishes the reaction normally.

[0062] In some embodiments, the kettle body 42 and the kettle cover 43 are covered by a quick-open clamp. The kettle body 42 has a variety of capacity specifications. The kettle cover 43 is provided with a bearing for supporting the stirring shaft 41. The pipe joint 44 is correspondingly connected to the external material conveying pipe. The temperature sensor is installed on the sensor joint 45 to monitor the reaction temperature in the reactor 4 so that the reaction device issues a warning when the temperature exceeds a threshold. The vacuum pipe of the condenser 46 is connected to an external vacuum pump or vacuum device to realize the recovery of the low-boiling point solvent volatilized in the reactor 4. A discharge valve 471 is usually provided on the discharge pipe 47. The discharge joint 48 is usually connected to an external discharge device to realize automatic discharge of the product after the reaction is completed.

[0063] Specifically, the mobile framework 2 includes:

[0064] The upper plate 21 is arranged on the upper part of the reaction kettle 4;

[0065] The lower plate 22 supports the bottom of the reaction kettle 4 at multiple supporting points from both sides of the reaction kettle 4 .

[0066] Furthermore, supporting rubber blocks 221 for buffering and vibration reduction are provided on the supporting points of the lower plate 22 .

[0067] In some embodiments, the lower plate 22 supports the bottom of the reactor 4, and the upper plate 21 clamps the upper part of the reactor 4 to limit its shaking around. The upper plate 21 and the lower plate 22 together fix the reactor 4 in the mobile frame 2. The upper outer wall of the reactor 4 can also be sleeved with a fixing ring 25 to form a step surface above the upper plate 21 to prevent the reactor 4 from falling after the lower plate 22 fails. The lower plate 22 is divided into two left and right plates, and a gap is opened to avoid the pipeline at the bottom of the reactor 4. The supporting rubber block 221 can prevent the support point of the lower plate 22 from hard contact with the reactor 4 and damage the wall of the reactor 4.

[0068] Specifically, the mobile frame 2 further includes a roller 23 with a locking function at the bottom thereof, and a liquid-carrying tray 24 located below the reactor 4. The roller 23 can make the pushing of the mobile frame 2 more labor-saving and flexible. The liquid-carrying tray 24 can prevent the material accidentally leaked from the reactor 4 from falling directly to the ground and causing pollution.

[0069] Specifically, guide bars 11 are provided on both sides of the opening of the main frame 1 , and the guide bars 11 are used to guide the mobile frame 2 to be pushed into a preset position in the main frame 1 .

[0070] like Figure 4 As shown, specifically, a door panel 12 is provided at the opening of the main frame 1, and the door panel 12 can open and close the opening.

[0071] In some embodiments, the guide bar 11 is horizontally arranged along the push-in and push-out direction of the mobile frame 2, and is located at the height of the reactor 4. A guide port is formed at the front end of the guide bar 11 to facilitate the push-in of the mobile frame 2. The door panel 12 is made of a transparent material, which can not only play a safety protection role, but also facilitate observation of the internal situation of the main frame 1.
