DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0031] Embodiment: Figure 1-8 As shown, a stirring type barium sulfate preparation reactor comprises a reactor body 1, and also comprises: a stirring assembly, wherein the stirring assembly is installed in the reactor body 1, the stirring assembly comprises a stirring part and a driving part, the stirring part can be expanded and retracted, the driving part is connected to the stirring part, and the stirring part is driven to expand and retract by the driving part; a power assembly, wherein the power assembly is installed on the reactor body 1, the power assembly is connected to the stirring assembly, and the stirring assembly can be driven to operate by the power assembly; an adjusting assembly, wherein the adjusting assembly is connected between the power assembly and the stirring assembly, and under the action of the adjusting assembly, the power assembly can drive the stirring part to reciprocately expand and retract and maintain a fixed expansion angle.

[0032] When in use, just put the raw materials needed for barium sulfate preparation into the reactor, and then the power component can be used to drive the stirring part of the stirring component to gradually open from a contracted state, thereby gradually expanding the stirring range. In this way, the starting resistance can be reduced. Afterwards, the stirring part can be adjusted to a fixed angle for stirring, and can also be continuously reciprocated and expanded, thereby obtaining a variety of different stirring modes to meet a variety of different stirring needs.

[0033] like Figure 3 As shown, the stirring part includes a first connecting rod 2 and a second connecting rod 3, the driving part includes a solid shaft 4, a hollow shaft 5, a first connecting seat 6 and a second connecting seat 7, the hollow shaft 5 is rotatably installed in the middle of the kettle body 1, the solid shaft 4 is passed through the middle of the hollow shaft 5, and the solid shaft 4 can rotate and slide in the hollow shaft 5, the first connecting seat 6 is fixedly connected to the hollow shaft 5, the second connecting seat 7 is rotatably connected to the bottom end of the solid shaft 4, one end of the first connecting rod 2 is rotatably connected to the first connecting seat 6, and the other end is rotatably connected to the end of the second connecting rod 3, and the end of the second connecting rod 3 away from the first connecting rod 2 is rotatably connected to the second connecting seat 7.

[0034] In this way, the solid shaft 4 only needs to slide up and down to drive the first connecting rod 2 and the second connecting rod 3 to rotate, thereby realizing the expansion and contraction of the stirring part and realizing the control of the stirring range.

[0035] There are a plurality of first connecting rods 2 and second connecting rods 3, which are evenly distributed in a circle with the axis of the hollow shaft 5 as the center, so that the stirring capacity can be further improved.

[0036] like Figure 5 , Figure 6 and Figure 7 As shown, the power assembly includes a motor 8, a transmission shaft 9, a first gear 10, a second gear 11, a bracket 12 and a linkage assembly. The bracket 12 is fixedly mounted on the kettle body 1, the motor 8 is fixedly mounted on the bracket 12, the transmission shaft 9 is rotatably mounted on the kettle body 1, and the transmission shaft 9 is coaxially connected with the output shaft of the motor 8, the first gear 10 is fixedly mounted on the transmission shaft 9, the second gear 11 is fixedly mounted on the surface of the hollow shaft 5, and the first gear 10 is meshed with the second gear 11, the linkage assembly is connected between the transmission shaft 9 and the solid shaft 4, and the transmission shaft 9 can drive the solid shaft 4 to slide along its axis through the linkage assembly.

[0037] In this way, it is only necessary to start the motor 8, the motor 8 will drive the transmission shaft 9 to rotate, the transmission shaft 9 will drive the second gear 11 to rotate through the first gear 10, and then drive the hollow shaft 5 to rotate, the hollow shaft 5 will drive the first connecting rod 2 to rotate synchronously through the first connecting seat 6, and then drive the second connecting rod 3 and the second connecting seat 7 to rotate to achieve stirring. At the same time, when the transmission shaft 9 rotates, it will also drive the solid shaft 4 to slide along its axis through the linkage assembly, so that the first connecting rod 2 and the second connecting rod 3 will rotate relative to each other, thereby achieving the contraction and expansion of the stirring part.

[0038] like Figure 5 , Figure 6 and Figure 7 As shown, the linkage assembly includes a reciprocating screw 13, a first threaded seat 14 and a linkage seat 15. The reciprocating screw 13 is coaxially connected to the transmission shaft 9. The first threaded seat 14 is threadedly installed on the surface of the reciprocating screw 13, and the threaded connection between the first threaded seat 14 and the reciprocating screw 13 is not self-locking. The linkage seat 15 is rotatably sleeved on the surface of the solid shaft 4 and can move synchronously with the solid shaft 4. The adjustment assembly includes a connecting assembly. The linkage seat 15 is detachably connected to the first threaded seat 14 through the connecting assembly. At the same time, after the linkage seat 15 is connected to the first threaded seat 14, the first threaded seat 14 can drive the linkage seat 15 to move synchronously.

[0039] In this way, when the transmission shaft 9 rotates, the first threaded seat 14 can be driven to move back and forth up and down continuously, and the first threaded seat 14 will drive the linkage seat 15 to move synchronously, thereby driving the solid shaft 4 to move synchronously. In this process, the linkage seat 15 can be controlled to separate from the first threaded seat 14 by adjusting the connecting component in the middle of the component, so that the linkage seat 15 is in a fixed position, thereby making the stirring range of the stirring part fixed. If the connecting component is always connected to the first threaded seat 14 and the linkage seat 15, the solid shaft 4 will continuously move back and forth up and down, which will cause the stirring part to continuously shrink and expand, thereby generating more turbulence, thereby facilitating the improvement of the stirring effect and stirring efficiency.

[0040] like Figure 5 , Figure 6 and Figure 7 As shown, the linkage assembly also includes a guide seat 16, a first guide rod 17, a guide groove 18 and a second guide rod 19. The guide seat 16 is fixedly mounted on the side of the first threaded seat 14, the first guide rod 17 is fixedly mounted in the middle of the bracket 12, and the guide seat 16 is slidably sleeved on the surface of the first guide rod 17. The guide groove 18 is opened on the side of the bracket 12, the second guide rod 19 is fixedly mounted on the side of the linkage seat 15, and the second guide rod 19 is slidably mounted in the guide groove 18.

[0041] In this way, under the action of the guide seat 16 and the first guide rod 17, the first threaded seat 14 will be able to maintain a fixed shape and move back and forth up and down. At the same time, under the action of the guide groove 18 and the second guide rod 19, the linkage seat 15 will be able to maintain a fixed state and move back and forth up and down, which will facilitate the connection between the first threaded seat 14 and the linkage seat 15 through the connecting assembly.

[0042] like Figure 4 and Figure 8 As shown, the connecting component includes a slot 20, a block 21, an active cavity 22 and a spring 23. The slot 20 is opened on the side of the first threaded seat 14, and the active cavity 22 is opened on the side of the linkage seat 15. The block 21 is slidably installed in the active cavity 22, and the block 21 and the slot 20 can cooperate with each other. At the same time, after the block 21 and the slot 20 cooperate, the first threaded seat 14 can drive the linkage seat 15 to move synchronously. The upper edge and the lower edge of the block 21 close to the slot 20 are both wedge-shaped. The spring 23 is connected between the block 21 and the inner wall of the active cavity 22, and the block 21 slides out of the active cavity 22 under the action of the spring 23.

[0043] In this way, the connection between the linkage seat 15 and the first threaded seat 14 can be released by simply retracting the block 21 into the active cavity 22. When the first threaded seat 14 needs to be reconnected with the linkage seat 15, the block 21 only needs to be slid out of the active cavity 22. At this time, since the upper and lower edges of the block 21 close to the slot 20 are both wedge-shaped, when the first threaded seat 14 is close to the linkage seat 15, the block 21 will be pushed into the active cavity 22 by the wedge-shaped surface of the block 21 until the slot 20 is aligned with the block 21, and the block 21 and the slot 20 will be engaged to achieve connection.

[0044] like Figure 5 , Figure 6 and Figure 7 As shown, the adjustment component also includes a thread groove 24, a second thread seat 25, a fixing component and a control component. The thread groove 24 is processed on the surface of the solid shaft 4. The second thread seat 25 is fixedly installed in the middle of the bracket 12, and the second thread seat 25 is threadedly connected to the thread groove 24 on the surface of the solid shaft 4. At the same time, the threaded connection between the second thread seat 25 and the thread groove 24 is not self-locking. The fixing component is installed on the bracket 12, and the solid shaft 4 can be fixed by the fixing component. The control component is connected between the block 21 and the fixing component, and after the block 21 is retracted into the active cavity 22, the control component can be triggered to drive the fixing component to operate.

[0045] In this way, under the action of the thread groove 24 and the second thread seat 25, when the entire reactor stops running, the solid shaft 4 will automatically slide down under the action of gravity until the first connecting rod 2 and the second connecting rod 3 tend to be collinear. At this time, the entire stirring part will be in a completely retracted state, thereby ensuring that the stirring part of each reactor is in a retracted state before starting, thereby achieving the effect of reducing the starting resistance;

[0046] During operation, if the solid shaft 4 needs to be kept at a fixed position, the solid shaft 4 can be stopped at a fixed position by limiting it through a fixing component so that it cannot rotate, thereby fixing the deployment range of the stirring part.

[0047] At the same time, during the operation, when the clamping block 21 is retracted into the movable cavity 22, the fixing component is driven to operate automatically through the control component, so that the automatic limit of the solid shaft 4 can be achieved.

[0048] like Figure 5 , Figure 6 and Figure 7As shown, the fixed assembly includes an electric push rod 26, a rotating sleeve rod 27, a transmission plug rod 28 and a friction block 29. The rotating sleeve rod 27 is rotatably installed in the middle of the bracket 12, and a plurality of friction grooves are processed on the surface. The transmission plug rod 28 is slidably inserted in the middle of the rotating sleeve rod 27 and can drive the rotating sleeve rod 27 to rotate synchronously. At the same time, the bottom end of the transmission plug rod 28 is fixedly connected to the top end of the solid shaft 4. The electric push rod 26 is fixedly installed on the bracket 12, and the friction block 29 is fixedly installed on the movable end of the electric push rod 26. The extension of the movable end of the electric push rod 26 can drive the friction block 29 to press against the friction groove on the surface of the rotating sleeve rod 27 to fix the rotating sleeve rod 27.

[0049] In this way, as long as the electric push rod 26 is started, the friction block 29 will be driven to be in close contact with the surface of the rotating sleeve rod 27, thereby limiting the rotating sleeve rod 27, and then limiting the transmission plug rod 28, and finally completing the limiting of the solid shaft 4.

[0050] like Figure 4 and Figure 8 As shown, the control component includes a proximity sensor 30 and an electromagnet 31. The electromagnet 31 and the proximity sensor 30 are both fixedly installed in the active cavity 22. When the electromagnet 31 is energized, it can attract the block 21 to retract into the active cavity 22 and trigger the proximity sensor 30. The proximity sensor 30 is electrically connected to the starting circuit of the electric push rod 26. At the same time, the power supply of the electric push rod 26 can be turned on after the proximity sensor 30 is triggered.

[0051] In this way, the card block 21 can be sucked into the active cavity 22 by simply starting the electromagnet 31. During this process, the proximity sensor 30 will be triggered synchronously to connect the power of the electric push rod 26. After the power of the electromagnet 31 is disconnected, the card block 21 will slide out of the active cavity 22 again under the action of the spring 23 to achieve reset.

[0052] Therefore, the complete usage process is that, in the initial state, the solid shaft 4 will continue to slide downward under its own gravity, thereby driving the first connecting rod 2 and the second connecting rod 3 to deflect, until the first connecting rod 2 and the second connecting rod 3 tend to be collinear, at this time the stirring part is in a contracted state, the stirring range is the smallest, so the stirring resistance is the smallest, at this time, start the motor 8, the motor 8 will drive the first gear 10 to rotate through the transmission shaft 9, the first gear 10 will drive the second gear 11 to rotate, and then drive the hollow shaft 5 to rotate, the rotation of the hollow shaft 5 will drive the first connecting rod 2 to rotate, and then drive the second connecting rod 3 to rotate to realize the rotation of the stirring part, and the rotation of the transmission shaft 9 will also drive the reciprocating screw 13 to rotate, which will drive the first threaded seat 14 to reciprocate along its axis, and the first threaded seat 14 will drive the linkage seat 15 to move synchronously, wherein, when the first threaded seat 14 drives the linkage seat 15 to move upward, it will synchronously drive the solid shaft 4 to move upward, which will drive the second connecting rod 3 and the first connecting rod 2 to rotate, so that the stirring part gradually expands, thereby increasing the stirring range, realizing large-area stirring, and the stirring part reaches the required After the stirring range is reached, the electromagnet 31 can be manually started, and the electromagnet 31 will attract the block 21 to retract into the active chamber 22. At this time, the connection between the block 21 and the slot 20 fails, and the first threaded seat 14 will not drive the linkage seat 15 to move. At the same time, after the block 21 slides into the active chamber 22, it will also trigger the proximity sensor 30, and the proximity sensor 30 will turn on the power of the electric push rod 26 to make it move, so that the friction block 29 is pressed against the rotating sleeve rod 27. At this time, the rotating sleeve rod 27 remains fixed, so the transmission plug rod 28 will also remain fixed. The solid shaft 4 will also remain fixed under the action of the thread groove 24 and the second thread seat 25, so as to achieve the fixation of the stirring range of the stirring part. In this way, the continuous rotation of the hollow shaft 5 can achieve the stirring demand inside the reactor. Conversely, the electromagnet 31 may not be started. In this way, the solid shaft 4 will continue to reciprocate up and down with the up and down reciprocating movement of the first thread seat 14, which will cause the stirring part to continuously shrink and expand, which will generate more turbulence inside the reactor, so that the stirring and mixing effect inside the reactor is better and more efficient.

[0053] In summary, during the entire use process, the stirring part in the stirring assembly can control the stirring range, and when starting the operation, it gradually expands from the contracted state, that is, the stirring range gradually expands. In this way, the starting resistance can be effectively reduced, thereby reducing the performance requirements of the driving equipment and the front-end power supply equipment, playing a role in reducing costs. At the same time, it can also play a certain role in equipment protection, and the function is more complete when used.

[0054] At the same time, during use, under the action of the adjustment component, the user can manually control the expansion and contraction state of the stirring part in the stirring component, so as to obtain different stirring capabilities. This will be able to adapt to the user's various different usage needs, greatly increase the scope of application, and further facilitate use.

[0055] In addition, during use, under the action of the adjusting component, the stirring part in the stirring component can also continuously shrink and expand, which will generate more turbulence inside the reactor, thereby improving the stirring efficiency and stirring effect, and the function is further improved.

[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
