[0062] Working principle:

[0063] During use of this device, the main threaded stirring rod 21 is driven to rotate by the first driving motor 1, thereby driving the semi-solid slurry entering the first pipe 3 and the second pipe 19 from the feed pipe 12 for transportation, and driving the semi-solid slurry to move in the first pipe 3 and the second pipe 19 toward the first connecting pipe 5 and the discharge pipe 17. The rotating motor drives the first secondary threaded stirring rod 22 and the second secondary threaded stirring rod 23 to rotate, thereby assisting the movement of the semi-solid slurry. An electric heating tape is provided inside the outer shell 4, which is connected to the external circuit through the electric heating tape to maintain the temperature of the first pipe 3 and the second pipe 19, so as to adapt to the temperature required by the semi-solid slurry and avoid overheating of the semi-solid slurry or an increase in the solid phase ratio due to insufficient temperature.

[0064] The temperature sensors installed in the first pipe 3 and the second pipe 19 monitor the temperature during the entire transportation process, which facilitates timely regulation and control to prevent the semi-solid slurry from overheating and becoming completely liquid during transportation or increasing the solid phase ratio to affect subsequent processing.

[0065] Example 1

[0066] In the external control system, the sensor reading temperature at the feed pipe 12 is set to a1, the sensor readings at the middle section of the first pipe 3 and the second pipe 19 are set to a2, and the temperature of the first connecting pipe 5 and the discharge pipe 17 is set to a3.

[0067] The a1 temperature is a fixed value. The semi-solid slurry is fed into the first pipe 3 through the feed pipe 12 by the preparation machine, and the main threaded stirring rod 21 is driven to work by the first drive motor 1. The main threaded stirring rod 21 drives the semi-solid slurry to be transported. If the a2 reading is consistent with a1 or the temperature difference between a1 and a2 is within ±5°C, the system determines that the value detected by the temperature sensor in the front section from the feed pipe 12 to the first pipe 3 and the second pipe 19 is normal, the entire equipment and the main threaded stirring rod 21 in the first pipe 3 and the second pipe 19 are working normally, no abnormal situation occurs, no remedial measures are required, and normal and operational transportation operations are carried out without the intervention of the temperature control mechanism and the reflux mechanism.

[0068] When the temperature a1 is consistent with the temperature a3 or the temperature difference between a1 and a3 is within ±5°C, the system determines that the entire equipment is operating in good condition throughout the entire process from the feed pipe 12 to the first connecting pipe 5 and the discharge pipe 17, and there are no defects in the conveying operation, which does not affect the subsequent normal use of the normal semi-solid slurry. The normal conveying operation is completed without affecting subsequent processing, and there is no need for the temperature control mechanism and the reflux mechanism to intervene, and the overall operation is normal.

[0069] When the temperature difference between a1 and a2 is 5°C, and the temperature difference between a2 and a3 is 5°C, that is, the temperature difference between a1 and a3 is 10°C, set ±10°C as the maximum warning value. When it exceeds 10°C, an alarm will be issued and the temperature control mechanism and the reflux mechanism will intervene.

[0070] In particular, under the limit value of 10°C, the temperature and solid phase ratio of the semi-solid slurry are detected by the temperature sensor provided in the discharge pipe 17. If the change in the solid phase ratio is within the range that can be normally used in the subsequent manufacturing process, the batch of semi-solid slurry is set to be qualified and can be used normally.

[0071] When a3-a1>10°C and the solid phase ratio test result is unqualified, the third reflux component intervenes and the first electric telescopic machine 16 drives the partition plate 59 to close the discharge pipe 17, and enters the third reflux pipe 15 through the discharge hole 31 and the discharge pipe 32 at the bottom of the first connecting pipe 5, and then returns to the interior of the first pipeline 3 for re-flow and transportation, and further heating or cooling treatment.

[0072] Furthermore, a third suction pump is provided inside the third reflux pipe 15 , and the semi-solid slurry is sent to the bottom of the first pipe 3 through the third suction pump.

[0073] When the difference between the temperature a1 and the temperature a2 is greater than 5°C but less than 10°C, there are two possibilities: when the temperature a2 is greater than the temperature a1, it is determined that the temperature at the first pipe 3 and the second pipe 19 is higher than the temperature when entering the feed pipe 12;

[0074] When the temperature a2 is lower than the temperature a1, it is determined that the temperatures in the first pipe 3 and the second pipe 19 are lower than the temperature in the feed pipe 12.

[0075] When the first pipe 3 and the second pipe 19 are at high temperatures, the temperature control component intervenes in the conveying operation and sends the cooling rod into the second pipe 19 through the replacement component to perform the cooling operation. At the same time, the temperature is read in real time through the sensor to avoid excessive cooling.

[0076] The specific replacement component cooling process is as follows: the cooling rod is grabbed by an external robotic arm and moved to the feed hole 10. The cooling rod is slowly pushed into the feed hole 10, and the third electric telescopic machine 49 in the fixed bar 46 drives the arc plate 50 to push the cooling rod to move, so that the cooling rod moves to above the entry end 24. The second electric telescopic machine 45 above the entry end 24 pushes the cooling rod into the entry end 24. When the cooling rod collides with the side wall of the entry end 24, the electric control valve at the end of the entry end 24 is opened, so that the cooling rod is extended. Enter the second pipe 19, and cool the pure copper at the end of the cooling rod through the cooling water circulation pipe to perform heat exchange and reduce the temperature of the semi-solid slurry in the second pipe 19. When the temperature a2 is the same as the temperature a1, the second electric telescopic machine 45 drives the cooling rod to slowly retreat, and at the same time closes the electric control valve. After standing for 2 minutes, the cooling rod temperature returns to normal, and then the second electric telescopic machine 45 drives the cooling rod back to the fixed bar 46. The arc plate 50 is driven by the third electric telescopic machine 49 to move the cooling rod back, and the cooling rod is taken out by the robotic arm.

[0077] When the temperature inside the first pipe 3 and the second pipe 19 is low, the temperature control component intervenes in the conveying operation, and sends the heating rod into the second pipe 19 through the replacement component to perform secondary heating operation. At the same time, the temperature is read in real time through the sensor to avoid overheating.

[0078] The specific heating process of the replacement component is basically the same as the cooling process. When power is turned on, the resistance material generates heat due to the current, converting electrical energy into thermal energy. The generated heat is conducted to the slurry through the metal sheath tube to heat the slurry, and then it is recycled after heating is completed.

[0079] The heating and cooling elements in the inlet end 24 of the second pipe 19 are replaced by replacing the components to ensure that the temperature in the middle section of the conveying is normal.

[0080] When the temperature a2 is higher than the temperature a1 by more than 10°C, the control system analyzes the situation by analyzing the temperature sensor readings, sets the temperature above the second pipe 19 to b1, and the temperature below the second pipe 19 to b2. If b1-a1≥10°C, the system controls the first reflux component to intervene.

[0081] The first reflux component sucks the semi-solid slurry above the top of the second pipe 19 through the first suction pump 13 set at the top, and returns the semi-solid slurry to the feed pipe 12 through the second reflux pipe 14. The outer circle of the second reflux pipe 14 is wrapped with a cooling pipeline, which cools the semi-solid slurry entering the feed pipe 12 to ensure that the temperature is consistent with a1.

[0082] If b2-a1≥10℃, the system controls the second reflux component to intervene in the conveying operation, and sends the semi-solid slurry with a temperature higher than a1 to the corrugated plate 55 in the vibration box 8 through the conveying pipe, and sends the semi-solid slurry into the reflux chamber 53 through the two inclined corrugated plates 55. During the process, the vibration motor 58 drives the vibration spring to drive the two corrugated plates 55 to vibrate, and the combined effect of vibration and shearing is used to break and refine the generated solid phase particles, and at the same time achieve cooling treatment, and the cooled semi-solid slurry is transported to the feed pipe 12 through the second suction pump 54.

[0083] Through the above steps, the judgment of abnormal a1 temperature and a2 temperature and subsequent remedial measures are realized. At the same time, the b1 temperature and b2 temperature are refined and refluxed, ensuring the normal operation of the device, the continuity of the semi-solid slurry transportation process and the stability of its physical composition.

[0084] Furthermore, when the b1 temperature and the b2 temperature are both higher than the a1 temperature, the first reflux component and the second reflux component work simultaneously. When the first suction pump 13 works alone, the suction power is set to E1, and the suction power of the second suction pump 54 is set to E2. The first suction pump 13 is used to pump with a power of 0.5E, and the slurry above the second pipe 19 is sent to the feed pipe 12 through the second reflux pipe 14, and refluxes into the first pipe 3 through the feed pipe 12. The second suction pump 54 is also used to pump with a power of 0.5E, and the slurry at the bottom of the second pipe 19 is sent into the feed pipe 12. The first reflux component and the second reflux component also work at a lower power to avoid the feed pipe 12 from being blocked due to too much feed pipe 12 in the same time.

[0085] Example 2

[0086] Flow rate detection sensors are set at the first connecting pipe 5, the discharge pipe 17, the first pipeline 3 and the second pipeline 19. The flow rate at the first connecting pipe 5 is set to C, and the flow rate in the first pipeline 3 and the second pipeline 19 is set to D. The replacement components are symmetrically arranged in two rows above and below.

[0087] When C=D, the flow rate is normal, and the system uses the temperature sensor to judge between the a1 temperature, a2 temperature, and a3 temperature. If there is no problem, it is output normally through the discharge pipe 17.

[0088] When C is less than D, the flow rate is abnormal, and the system compares the temperature a2 with the temperature a3. When the temperature a3 is less than the temperature a2, the system attempts to resolve the abnormality by intervening with a replacement component. When the cooling effect is not obvious and the flow rate is still abnormal, it can be speculated that the semi-solid slurry in the second pipe 19 may be blocked. At this time, the system control and adjustment component intervenes to verify whether there is a blockage.

[0089] When it is detected that C<D and b2<b1, the heating rod is inserted into the interior of the second pipe 19 to heat the semi-solid slurry in the second pipe 19. At this time, it is determined whether the heating at b1 and b2 is uniform:

[0090] After the heating rod enters the second pipe 19, by continuously monitoring the flow rate C, the flow rate is set to C1 one minute after the heating rod enters, and the flow rate is set to C2 after a period of time, C1=C2, and the temperature difference between b1 and b2 is within ±1°C. It is concluded that the heating rod heats the semi-solid slurry in the upper and lower parts of the second pipe 19 evenly, and the heat treatment is uniform.

[0091] After the heating rod enters the second pipe 19, after a period of time, when C1≠C2 and the temperature difference between b1 and b2 remains at the difference before the heating rod enters the second pipe 19, it is concluded that the heating is uneven.

[0092] When heating is uneven within the same time, keep monitoring the temperatures at b1 and b2. When b1-a1=5°C, stop heating and compare the temperatures of b1 and b2. If the temperature rise at b1 is greater than the temperature rise at b2, it can be concluded that the amount of semi-solid slurry above the second pipe 19 is less than that below the second pipe 19, and the heating difficulty is lower. It can be determined that b2 is blocked and it can be unblocked through the guide plate 25 provided at the bottom of the second pipe 19.

[0093] The first rotating rod 27 is driven to rotate by the second driving motor 26, and then the second transmission gear 36 mounted on the first rotating rod 27 is driven to rotate. The second transmission gear 36 is engaged with the second rotating ring 37 in the first connecting tube 5, further driving the second rotating ring 37 to rotate, and the second rotating rod 40 is driven to rotate by the second rotating ring 37. During the rotation of the second rotating rod 40, the push rod 38 is driven to push the transmission joint 43 to deflect, and the guide plate 25 is driven to deflect in the second pipe 19 through the universal ball 44, thereby performing the dredging operation inside the second pipe 19. By setting a resistance sensor on the guide plate 25, the system reads the reading on the resistance sensor. When the reading is greater than the set value, it is determined that the middle section of the second pipe 19 is blocked. The guide plate 25 is deflected at the bottom of the second pipe 19 to stir the bottom slurry to avoid blockage caused by slurry accumulation.

[0094] Furthermore, the control system controls the main threaded stirring rod 21 to maintain forward rotation, setting the speed to V0. The control system also controls the first and second threaded stirring rods 22, 23 to rotate in the opposite direction, setting the speed to 0.6V0. This reverse shear force causes the semi-solid slurry in region b2 to reflux and rotate to region b1, thereby performing heat exchange. After a period of time, the temperature difference between regions b1 and b2 is determined.

[0095] If the rising temperature at b1 = the rising temperature at b2, it is determined that there is no temperature difference between the upper and lower areas in the second pipe 19, and the first secondary threaded stirring rod 22 and the second secondary threaded stirring rod 23 are restored to the same direction as the main threaded stirring rod 21, and the rotation speed is also restored to the same, and the conveying operation is carried out normally.

[0096] If the temperature rise at b1 is greater than the temperature rise at b2, it can be concluded that the amount of semi-solid slurry above the second pipe 19 is less than that below the second pipe 19, and the heating difficulty is lower. The semi-solid slurry below the second pipe 19 is blocked. At this time, the second reflux component intervenes to assist the semi-solid slurry to flow back into the feed pipe 12, and synchronous dredging treatment is performed by reducing the semi-solid slurry in the lower half of the second pipe 19.

[0097] When C approaches 0 and b1-b2≥10℃, the system automatically determines that the middle section of the second pipe 19 is completely blocked. By rotating the motor, the first secondary thread stirring rod 22 and the second secondary thread stirring rod 23 rotate in the opposite direction, which is opposite to the stroke of the first main thread stirring rod 21, generating countercurrent shear force to break up particles and clear the second pipe 19. At the same time, the replacement component is assembled to assemble the heating rod, and the heating rod is inserted into the interior of the second pipe 19 for rapid heating. The changes between the a2 temperature and the a3 temperature are observed in real time. If the temperature change is not obvious, or the a3 temperature is more than 10℃ lower than the a1 temperature, the system controls the third reflux component to intervene.

[0098] The partition plate 59 is controlled by the first electric telescopic machine 16 to close the discharge pipe 17, and the second drive motor 26 drives the first rotating rod 27 to deflect. The first rotating rod 27 drives the first rotating ring 29 to rotate through the first transmission gear 28, driving the circular hole opened on the first rotating ring 29 to rotate to the top of the discharge hole 31. The semi-solid slurry enters the discharge pipe 32 through the discharge hole 31, and the movable column 34 in the discharge pipe 32 is squeezed to move the movable column 34 into the extension pipe 33, so that the semi-solid slurry enters the third return pipe 15 and refluxes into the first pipe 3 for secondary heating to ensure that the temperature of the semi-solid slurry meets the required range.

[0099] In particular, the first rotating rod 27 simultaneously controls the third reflux component and the adjustment component. By pre-setting the rotation parameters in the system, the movable range of the movable rod 41 is -30°-30°, and an electric control valve is set at the top of the discharge pipe 32. The movable range of the first rotating ring 29 is also -30°-30°, and the circular hole opened on the first rotating ring 29 is set in the middle of the movable range.

[0100] Through the above measures, it is determined whether the middle sections of the first pipe 3 and the second pipe 19 are blocked, and the reflux component and the regulating component are controlled to make further determinations and remedies, thereby ensuring the normal transportation of the semi-solid slurry.
