[0047] See also Figure 1 、 Figure 10As shown, the present invention is a binder mixing device, comprising a tank body 1, a stirring mechanism 2 installed in the tank body 1, a detection mechanism 3 for detecting the viscosity of the binder in the tank body 1 is installed on the stirring mechanism 2; the detection mechanism 3 comprises a hydraulic drive component, a transmission component and a control disk 31, the control disk 31 is movably installed on the upper end of the stirring mechanism 2 and is located outside the tank body 1, the hydraulic drive component is installed inside the stirring mechanism 2, and is connected to the control disk 31 through the transmission component; when the stirring mechanism 2 rotates, the hydraulic drive component is driven to rotate synchronously in the binder in the tank body 1, so that the hydraulic drive component drives the control disk 31 to move upward along the stirring mechanism 2 through the transmission component under the action of the hydraulic resistance of the binder; the tank body 1 is also equipped with a control disk for discharging The discharging mechanism 4 of the binder and the cleaning mechanism 5 for cleaning the inner wall of the tank body 1; the discharging mechanism 4 is installed at the bottom end of the tank body 1, and when the transmission assembly drives the control disk 31 to move upward to the highest point, the transmission assembly drives the discharging mechanism 4 to be fixedly docked with the stirring mechanism 2, so that the stirring mechanism 2 drives the discharging mechanism 4 to rotate synchronously to discharge the binder from the tank body 1; the cleaning mechanism 5 is installed in a lifting manner on the inner wall of the tank body 1, and when the binder in the tank body 1 is discharged and the hydraulic drive assembly is no longer subjected to the hydraulic resistance of the binder, the transmission assembly drives the control disk 31 to move downward along the stirring mechanism 2 to reset, and at the same time, the transmission assembly drives the cleaning mechanism 5 to be connected to the stirring mechanism 2, so that the stirring mechanism 2 drives the cleaning mechanism 5 to move up and down along the inner wall of the tank body 1;

[0048] When the stirring mechanism 2 rotates, it drives the hydraulic drive component to rotate synchronously in the mixed solution of the binder and the raw material inside the tank body 1, so that the hydraulic drive component drives the control disk 31 to move upward along the stirring mechanism 2 through the transmission component under the action of the hydraulic resistance of the mixed solution. As the binder in the tank body 1 is gradually generated, the adhesion of the mixed solution increases. At this time, the hydraulic resistance encountered by the hydraulic drive component during the movement becomes larger, so that the hydraulic drive component drives the control disk 31 to continue to move upward through the transmission component. When the binder in the tank body 1 is prepared, the viscosity of the solution in the tank body 1 reaches the maximum value, so that the hydraulic resistance encountered by the hydraulic drive component reaches the maximum value. Under the action of hydraulic resistance, the hydraulic drive assembly drives the discharging mechanism 4 through the transmission assembly to be fixedly connected to the stirring mechanism 2, so that when the stirring mechanism 2 rotates, the discharging mechanism 4 is driven to work, and the binder in the tank body 1 is gradually discharged. After the binder in the tank body 1 is discharged, the hydraulic drive assembly is no longer subjected to the hydraulic resistance of the binder, and the transmission assembly drives the control disk 31 to move downward along the stirring mechanism 2 to reset. At the same time, the transmission assembly drives the cleaning mechanism 5 to be connected to the stirring mechanism 2, so that the stirring mechanism 2 drives the cleaning mechanism 5 to move up and down along the inner wall of the tank body 1, thereby cleaning the inner wall of the tank body 1, removing the binder adhered to the inner wall of the tank body 1, and restoring the interior of the tank body 1 to be clean.

[0049] In the present invention, the viscosity of the mixed solution in the tank body 1 can be intuitively reflected through the height of the control plate 31, thereby facilitating the staff to monitor the preparation process of the binder in the tank body 1 without the need for sampling and then testing, thereby making the detection process of the binder more convenient and quicker, so that the staff can monitor the preparation process of the binder, and at the same time it is beneficial to improve the preparation efficiency of the binder; through the cooperation of the stirring mechanism 2, the detection mechanism 3 and the discharging mechanism 4, the discharging process of the binder can be automatically carried out after the preparation of the binder is completed, making the discharging of the binder more convenient and quicker.

[0053] When the stirring blade 23 rotates, it drives the pressure plate 33 to make a circular motion in the tank body 1. During the circular motion, the pressure plate 33 is subjected to the hydraulic resistance of the mixed solution in the tank body 1, so that the pressure plate 33 slides toward the inside of the pressure cylinder 32 under the action of the hydraulic resistance, thereby driving the active wedge block 35 to slide inward. During the inward sliding process, the active wedge block 35 pushes the driven wedge block 36 and the push rod 37 toward the rotating shaft 22 through the inclined surface. At the same time, the No. 1 return spring 39 is squeezed and contracted, and its return elastic force increases.

[0055] When the push rod 37 moves toward the rotating shaft 22, the push rod 37 pushes the push block 310 to the left. At this time, the push block 310 pushes the upper wedge block 311 and the push-pull rod 313 upward through the top inclined surface. At the same time, the No. 2 return spring 312 is squeezed and contracted to generate a return elastic force. When the push-pull rod 313 moves upward, it drives the guide slider 34 at its top to slide upward along the guide groove 314, thereby driving the control disk 31 to move upward through the guide slider 34.

[0061] When the binder in the tank body 1 is discharged outward and the control disc 31 moves downward to reset, the control disc 31 drives the positioning shaft 54 ​​to move downward, so that the positioning shaft 54 ​​is gradually inserted into the positioning hole 56, thereby locking the control disc 31 and the driving wheel 55. Afterwards, as the rotating shaft 22 continues to rotate, the rotating shaft 22 drives the driving wheel 55 to rotate synchronously through the control disc 31, thereby driving the driven wheel 58 to rotate through the transmission belt 57, and then the driven wheel 58 drives the reciprocating screw rod 51 to rotate. During the rotation process, the reciprocating screw rod 51 drives the lifting ring 52 to move back and forth in the tank body 1 through the threaded transmission, thereby driving the scraper ring 510 to move back and forth along the inner wall of the tank body 1 to scrape and clean the inner wall of the tank body 1.

[0062] For further information, see Figures 1-10 As shown, in one embodiment, an application of a binder mixing device in the preparation of a binder for special refractory materials is disclosed. Taking the phenolic resin binder commonly used in special refractory materials as an example, a mixed solution of benzene and formaldehyde and a catalyst are added to a tank body 1, and then a motor 21 drives a rotating shaft 22 to rotate, thereby driving a plurality of stirring blades 23 to rotate synchronously in the tank body 1 through the rotating shaft 22 to stir the mixed solution in the tank body 1, so that the solution is mixed more evenly, and the phenolic resin binder is gradually generated;

[0063] When the stirring blade 23 rotates, it drives the pressure plate 33 to make a circular motion in the tank body 1. During the circular motion, the pressure plate 33 is subjected to the hydraulic resistance of the mixed solution in the tank body 1, so that the pressure plate 33 slides toward the inside of the pressure cylinder 32 under the action of the hydraulic resistance, thereby driving the active wedge block 35 to slide inward. During the inward sliding process, the active wedge block 35 pushes the driven wedge block 36 and the push rod 37 toward the rotating shaft 22 through the inclined surface. At the same time, the No. 1 return spring 39 is squeezed and contracted, and its return elastic force increases. When the binder in the tank body 1 is gradually generated to increase the viscosity of the mixed solution in the tank body 1, the hydraulic resistance experienced by the pressure plate 33 increases accordingly, and the pressure plate 33 continues to move inward, and the No. 1 return spring 39 continues to be squeezed and contracted.

[0064] When the push rod 37 moves toward the rotating shaft 22, the push rod 37 pushes the push block 310 to the left. At this time, the push block 310 pushes the upper wedge block 311 and the push-pull rod 313 upward through the top inclined surface. At the same time, the second return spring 312 is squeezed and contracted to generate a return elastic force. When the push-pull rod 313 moves upward, it drives the guide slider 34 at its top to slide upward along the guide groove 314, thereby driving the control plate 31 upward through the guide slider 34.

[0065] When the pushing block 310 moves to the left, it also pushes the lower wedge block 411 downward through the inclined surface at the lower end, so that the No. 3 return spring 412 is gradually squeezed and contracted. At the same time, the clutch wheel 48 is pushed downward through the connecting rod 413, so that the pin 47 on the bottom surface of the clutch wheel 48 gradually approaches the turntable 45. Until the preparation of the binder in the tank body 1 is completed, the viscosity in the tank body 1 reaches the maximum value and the hydraulic resistance of the pressure plate 33 reaches the maximum, the pin 47 is abutted and moved to the lowest position, and inserted The pin hole 46 on the top surface of the turntable 45 is inserted into the pin hole 46, and the turntable 45 is locked and connected with the clutch wheel 48. After that, as the rotating shaft 22 continues to rotate, the rotating shaft 22 drives the turntable 45 to rotate synchronously through the clutch wheel 48, thereby driving the feeding auger 42 to rotate, and the feeding auger 42 squeezes and feeds the binder. At this time, the pressure valve 43 is opened under the hydraulic pressure of the binder driven by the feeding auger 42, so that the binder is gradually discharged from the discharge pipe 41, realizing automatic discharge of the binder;

[0066] When the binder is discharged, the pressure plate 33 is no longer affected by the hydraulic resistance. At this time, the pressure plate 33, the control plate 31 and the clutch wheel 48 are all moved and reset under the reset elastic force of the reset spring.

[0067] When the binder in the tank body 1 is discharged outward and the control disc 31 moves downward to reset, the control disc 31 drives the positioning shaft 54 ​​to move downward, so that the positioning shaft 54 ​​is gradually inserted into the positioning hole 56, thereby locking the control disc 31 and the driving wheel 55. Afterwards, as the rotating shaft 22 continues to rotate, the rotating shaft 22 drives the driving wheel 55 to rotate synchronously through the control disc 31, thereby driving the driven wheel 58 to rotate through the transmission belt 57, and then the driven wheel 58 drives the reciprocating screw rod 51 to rotate. During the rotation process, the reciprocating screw rod 51 drives the lifting ring 52 to move back and forth in the tank body 1 through the threaded transmission, thereby driving the scraper ring 510 to move back and forth along the inner wall of the tank body 1 to scrape and clean the inner wall of the tank body 1.
