Description

Technical Field

[0001] The invention relates to the technical field of insulating skin raw material stirring, in particular to a stirring device for producing raw material of polyvinyl chloride insulating skin of external data line. Background Art

[0002] Data cables are often used for data transmission and hardware connection. Some data cables also have charging functions. In the process of data cable production, polyvinyl chloride is often used to make insulation on the outside of data cables because of its wear resistance and flexibility. The polyvinyl chloride insulation needs to go through mixing and plasticizing, extrusion molding, cooling and shaping during production.

[0003] In the above production process, the production raw materials need to be put into the reactor in a certain proportion, and the reactor is used to fully stir and mix the raw materials. In the existing stirring and mixing equipment, the stirring and mixing efficiency of the raw materials is improved by heating and stirring. However, the raw materials are prone to adhere to the inner wall of the equipment during stirring, and the occurrence of adhesion is prone to uneven heating and coking of the materials.

[0004] And when heat is transferred, due to the adhesion and accumulation of raw materials, the contact area between the inner wall of the equipment and the material being stirred will be reduced, which will weaken its heat transfer efficiency and also have a certain impact on the stirring efficiency of the material.

[0005] To this end, the inventors have designed and developed a mixing device for the production of raw materials for the external polyvinyl chloride insulation of data cables. While improving the heat transfer efficiency during the material mixing process, it can also avoid the occurrence of coking due to uneven heating of the material caused by adhesion and deposition problems.

[0015] Preferably, a spoiler assembly is rotatably provided on the first connecting seat, and the spoiler assembly includes a transmission shaft rotatably provided with the first connecting seat, and a synchronization shaft rotatably provided with the second connecting seat, and both the transmission shaft and the synchronization shaft are provided with spoiler blades.

[0016] Preferably, the transmission shaft is provided with a synchronous gear meshing with the spur rack, and both ends of the transmission shaft are provided with a universal coupling for driving the synchronous shaft to rotate synchronously.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By driving the motor to control the forward and reverse rotation of the shaft, not only can the conventional stirring of the material by the stirring paddle be achieved, but also, when rotating in the reverse direction, the reciprocating screw can be driven to rotate synchronously through the rotation coordination of the ratchet pawl, and then the adhesions on the arc-shaped fins can be scraped off through the scraping component, effectively reducing the problem of reduced heat transfer efficiency of the arc-shaped fins due to long-term accumulation of adhesions, and simultaneously avoiding the problem of reduced stirring efficiency due to reduced heat transfer efficiency.

[0021] Through the design of the hollow cavity in the arc-shaped fins and the jacket on the outside of the stirred reactor, the circulating heating liquid can be fully utilized to heat the stirred reactor and the arc-shaped fins. Compared with the conventional stirred reactor, the heat transfer area between the inner wall and the material is increased. Under the premise of ensuring the appropriate temperature of the material during the stirring process, the stirring efficiency of the material can be improved.

[0022] By rotating the shaft in the opposite direction and utilizing the matching effect of the second pawl plate and the second ratchet plate, the through shaft drives the bottom cleaning frame to stir the materials at the bottom of the inner cavity of the stirred reactor, effectively preventing the deposition and coking of the materials and ensuring the uniformity and thoroughness of the stirring.

[0023] By setting the bottom cleaning frame, when the material is discharged through the discharge pipe, the continuous rotation of the bottom cleaning frame helps to offset the vortex generated by the material flowing through the discharge pipe, prevents material retention and improves the discharge efficiency of the material.

[0024] Through the design of the scraping component and the spoiler component, not only the accumulation of adhesion on the curved fins is reduced, but the scraping effect is also enhanced through the impact of the spoiler liquid, avoiding the decline in equipment performance and the increase in cleaning costs caused by long-term fouling.

[0025] By precisely controlling the operation of the heating system and the stirring system, unnecessary energy consumption is avoided, and secondary pollution caused by material retention and sedimentation is reduced, which is in line with the concept of energy conservation and environmental protection.

[0026] In summary, the present invention overcomes the shortcomings of the prior art, optimizes the internal heat transfer efficiency of a conventional stirring tank, and simultaneously optimizes and improves the adhesion of materials during stirring, thereby avoiding the adhesion of materials during the stirring process affecting the efficiency of material stirring, and has high social use value and application prospects.

[0051] Specifically, the transmission shaft 81 is provided with a synchronous gear 802 that meshes with the spur rack 32, and both ends of the transmission shaft 81 are provided with universal couplings 83 for driving the synchronous shaft 82 to rotate synchronously. With the up and down reciprocating movement of the adjustment component 6, the spoiler component 8 can be driven to move synchronously through the scraper component 7. At this time, the synchronous gear 802 can generate meshing and matching rotation with the spur rack 32, thereby allowing the transmission shaft 81 to rotate, and through the setting of the universal coupling 83, the synchronous shaft 82 can be driven to rotate synchronously without providing an additional separate power input device. Example

[0052] Reference Figure 1-12 The difference between this embodiment and embodiment 1 is that a connecting shaft 9 is rotatably provided on the top surface of the inner cavity of the stirred reactor 1, and a second ratchet disk 91 is rotatably matched with the second ratchet disk 42 at the bottom end of the connecting shaft 9. Through the setting of the connecting shaft 9, when the rotating shaft 4 rotates in the opposite direction, the first ratchet disk 41 will rotate and match with the first ratchet disk 51, and at the same time, the second ratchet disk 42 will also rotate and match with the second ratchet disk 91, so that the connecting shaft 9 can also rotate synchronously when the reciprocating screw rod 5 rotates, which plays a role in assisting the scraping of adhesions.

[0053] Specifically, a through shaft 901 movably mounted with the inner cavity of the rotating shaft 4 is provided at the bottom of the second ratchet disk 91, and a bottom cleaning frame 92 acting on the bottom surface of the inner cavity of the stirred reactor 1 is provided at the bottom end of the through shaft 901. Through the provision of the through shaft 901, when the connecting shaft 9 rotates, the through shaft 901 can drive the bottom cleaning frame 92 to act on the bottom surface of the inner cavity of the stirred reactor 1, disturb the material deposited on the bottom surface of the inner cavity of the stirred reactor 1, and scrape off the attachments adhered to the bottom surface of the inner cavity of the stirred reactor 1, so as to avoid a large amount of accumulation during the material stirring process.

[0054] For other structures not described, refer to Example 1.

[0055] Working principle: In the present invention, firstly, through the adjustment of the internal components, the adjustment seat 601 is placed at the highest point outside the reciprocating screw 5. At this time, the scraping component 7 and the spoiler component 8 are also at the highest point on the surface of the arc fin 3. The connection between the jacket 2 and the external heating pipeline is opened to allow the circulating heating liquid to enter the space between the stirred reactor 1 and the jacket 2 and the hollow cavity 31, so as to increase the temperature of the stirred reactor 1 and the arc fin 3, so as to provide a suitable temperature for stirring. Then, the material to be stirred is put into the stirred reactor 1 through the feeding pipe 101, and then the reverse rotation of the output shaft of the driving motor 104 is turned on, so that the output shaft of the driving motor 104 drives the main shaft 1041 to rotate, so that the main shaft 1041 drives the driving gear 1042 to rotate, so that the driving gear 1042 is meshed and matched with the driven gear 421, so that the rotating shaft 4 can rotate forward, and then the stirring paddle 401 stirs the material in the stirred reactor 1.

[0056] When there is a problem of adhesion of materials inside the stirred reactor 1, the output shaft of the driving motor 104 is adjusted from reverse rotation to forward rotation, so that the rotating shaft 4 can rotate in the reverse direction, so that the first pawl disk 41 can rotate and match with the first ratchet disk 51 at this time, so that the rotating shaft 4 can make the reciprocating screw 5 rotate synchronously when the rotating shaft 4 rotates, so that the adjustment seat 601 on the surface of the reciprocating screw 5 can move downward, and the adjustment seat 601 can reciprocate up and down with the rotation of the reciprocating screw 5;

[0057] As the adjusting component 6 moves, it can synchronously change the relative position between the scraping component 7 and the arc-shaped fin 3, and the scraping strip 702 can act on the surface of the arc-shaped fin 3 as it moves, and scrape off the adhered materials on the surface of the arc-shaped fin 3 caused by stirring, so as to avoid the reduction of the heat transfer efficiency of the arc-shaped fin 3 due to the accumulation of materials, and can also avoid the phenomenon of coking caused by the long-term adhesion of the adhered materials;

[0058] When the adjustment component 6 and the scraping component 7 are adjusted in position, the synchronous gear 802 can be meshed with the spur rack 32, so that the transmission shaft 81 can rotate. By utilizing the transmission effect of the universal coupling 83, the synchronous shaft 82 can synchronize the rotation of the transmission shaft 81, so that the spoiler blade 801 can stir the liquid near the surface of the arc-shaped fin 3. Through the impact of the spoiler liquid, when the scraper bar 702 scrapes the surface of the arc-shaped fin 3, the problem of accumulation of the scraped material can be effectively avoided, and the scraper bar 702 can also play a certain cleaning role.

[0059] When the rotating shaft 4 rotates in the opposite direction to drive the reciprocating screw rod 5 to rotate, the second pawl plate 42 can rotate in matching with the second ratchet plate 91, so that the through shaft 901 can rotate synchronously with the rotating shaft 4, so that when the stirring paddle 401 stirs the material, the bottom cleaning frame 92 can stir the material deposited at the bottom of the inner cavity of the stirring reactor 1 to prevent the material from sinking to the bottom due to sedimentation.

[0060] After the material is fully stirred, the discharge pipe 102 is opened to allow the material to be discharged and collected through the discharge pipe 102 for the next step of processing. When the material is discharged through the discharge pipe 102, the bottom cleaning frame 92 will continue to rotate under the driving action of the through shaft 901 to offset the vortex generated by the material being discharged through the discharge pipe 102, thereby improving the discharge efficiency of the material and avoiding excessive vortex causing part of the material to be retained inside the stirred reactor 1.
