[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] 1. The utility model starts the power supply, the motor starts to run, and drives the stirring shaft and blades to start rotating in the cylinder. At this time, the filter cake and water begin to enter the cylinder from the feed port. The filter cake entering the cylinder is broken up by the blades. After the filter cake is broken up and stirred, it is fully mixed with water to form slurry. Then, filter cake and water are continuously added to the cylinder through the feed port.

[0016] 3. The utility model is provided with a slag discharge pipe. When the slag is deposited and accumulated at the inner bottom of the cylinder, the rotating shaft is rotated to drive the auger to rotate. The auger can drive the slag inside the cylinder and the slag discharge pipe downward, so that the slag is gathered in the slag discharge pipe. The rotating shaft continues to rotate, and the auger moves the slag in the slag discharge pipe downward. The slag squeezes the sealing ring until the sealing ring is separated from the sealing disk, and the slag falls from the gap between the sealing disk and the slag discharge pipe and is discharged from the central through hole of the sealing disk, thereby achieving the effect of slag discharge. Moreover, since the slag blocks the slag discharge pipe, the slurry in the cylinder will not be discharged from the slag discharge pipe. The operation is simple and convenient. After the slag is discharged, the elastic force of the spring makes the sealing ring stick to the sealing disk, thereby achieving the effect of sealing the slag discharge pipe, preventing the slurry in the cylinder from being discharged from the slag discharge pipe.

DETAILED DESCRIPTION

[0025] Example:

[0026] like Figure 1-Figure 5As shown, an embodiment of the utility model provides a filter cake continuous breaking up, crushing and repulping machine, comprising a motor 1, a coupling 2, a cylinder 3, and a feed port 4. The coupling 2 is fixedly arranged on the left side of the motor 1, the cylinder 3 is fixedly arranged on the left side of the coupling 2, the feed port 4 is penetrated through the right side of the upper surface of the cylinder 3, and the maintenance port 5 is fixedly arranged on the left side of the upper surface of the cylinder 3. The left end of the cylinder 3 is fixedly connected with a discharge end 14 through a French joint, an overflow plate 13 is arranged at the connection between the discharge end 14 and the cylinder 3, an overflow port 1301 is opened above the overflow plate 13, a visual window 6 is arranged above the discharge end 14, a discharge port 7 is penetrated through the bottom of the discharge end 14, a supporting leg 8 is fixedly arranged on the bottom of the cylinder 3, a slag discharge pipe 9 is penetrated through the center of the bottom of the cylinder 3, a stirring shaft 10 is fixedly arranged on the left end of the coupling 2, a plurality of blades 12 are fixedly arranged on the outer surface of the stirring shaft 10, and a plurality of stirring pins 11 are fixedly arranged on the inner surface of the cylinder 3.

[0027] During actual use, by starting the power supply, the motor 1 starts to run, driving the stirring shaft 10 and the blades 12 to start rotating in the cylinder 3. At this time, the filter cake and water begin to enter the cylinder 3 from the feed port 4. The filter cake entering the cylinder 3 is broken up by the blades 12. After the filter cake is broken up and stirred, it is fully mixed with water to form a slurry. Then, filter cake and water are continuously added to the cylinder 3 through the feed port 4. When the slurry reaches a certain height in the cylinder 3, it overflows to the discharge end 14 through the overflow port 1301 on the overflow plate 13. The slurry is discharged through the discharge port 7 to achieve the effect of slurry production. During the crushing and re-pulping process, the equipment does not need to be stopped to discharge the slurry, and can continuously perform the breaking, crushing and re-pulping operations, thereby greatly improving the production efficiency.

[0028] In this embodiment, the blades 12 and the stirring pins 11 are staggeredly distributed in the cylinder 3, so that the blades 12 can continuously pass between the two stirring pins 11 when rotating, so that the blades 12 can cooperate with the stirring pins to crush the filter cake, and the crushing effect is better.

[0029] In this embodiment, four stirring pins 11 are arranged on the same vertical plane, and the angle between two adjacent stirring pins 11 is 90°.

[0030] By providing a stirring pin 11, and by providing a stirring pin 11 in the cylinder 3, when the stirring shaft 10 drives the blade 12 to rotate, the blade 12 continuously passes between adjacent stirring pins 11. When the filter cake is placed on the stirring pin 11, the blade 12 passes between two stirring pins 11, which makes it easier for the blade 12 to crush the filter cake and increases the crushing effect.

[0031] In this embodiment, the slag discharge pipe 9 includes a cross bar 901, a rotating shaft 902, an auger 903, a sealing disk 904, a fixing ring 905, a spring 906 and a sealing ring 907. The cross bar 901 is fixedly arranged at the inner center of the slag discharge pipe 9, the auger 903 is fixedly arranged above the outer surface of the cross bar 901, the sealing disk 904 is fixedly arranged below the outer surface of the rotating shaft 902, the fixing ring 905 is fixedly arranged at the inner bottom of the slag discharge pipe 9, a plurality of springs 906 are fixedly arranged above the fixing ring 905, and a sealing ring 907 is fixedly arranged on the top of the spring 906.

[0032] In this embodiment, the sealing ring 907 is airtightly connected to the inner surface of the slag discharge pipe 9, and the diameter of the central through hole of the sealing ring 907 is smaller than the diameter of the sealing disk 904. The diameter of the sealing disk 904 is smaller than the inner diameter of the slag discharge pipe 9, which facilitates the slag to fall from the gap between the sealing disk 904 and the slag discharge pipe 9 to the central through hole of the sealing ring 907 for discharge.

[0033] In this embodiment, the spring 906 is in a compressed state, and the upper surface of the sealing ring 907 is in close contact with the bottom surface of the sealing disk 904, thereby achieving the effect of sealing the slag discharge pipe 9 and preventing the slurry in the cylinder 3 from being discharged from the slag discharge pipe 9.

[0034] In this embodiment, the diameter of the auger 903 is equal to the inner diameter of the slag discharge pipe 9, and the auger 903 is in the slag discharge pipe 9. The top of the auger 903 extends out of the top of the slag discharge pipe 9, which makes it convenient for the auger 903 to guide the slag in the cylinder 3 into the slag discharge pipe 9, thereby facilitating the discharge of the slag.

[0035] In this embodiment, the bottom of the rotating shaft 902 extends out of the bottom of the slag discharge pipe 9, and a turning handle is fixedly provided at the bottom of the rotating shaft 902, so that the rotating shaft 902 can be driven to rotate by the turning handle.

[0036] By providing a slag discharge pipe 9, when the slag is deposited and accumulated at the inner bottom of the cylinder 3, the rotating shaft 902 is rotated, and the rotating shaft 902 drives the auger 903 to rotate. The auger 903 can drive the slag inside the cylinder 3 and the slag discharge pipe 9 downward, so that the slag is gathered in the slag discharge pipe 9. The rotating shaft 902 continues to rotate, and the auger 903 moves the slag in the slag discharge pipe 9 downward, and the slag squeezes the sealing ring 907 until the sealing ring 907 is separated from the sealing disk 904, and the slag is discharged. The slag falls from the gap between the sealing disk 904 and the slag discharge pipe 9, and is discharged from the central through hole of the sealing disk 904, thereby achieving the slag discharge effect. Since the slag blocks the slag discharge pipe 9, the slurry in the cylinder 3 will not be discharged from the slag discharge pipe 9. The operation is simple and convenient. After the slag is discharged, the elastic force of the spring 906 makes the sealing ring 907 stick to the sealing disk 904, thereby achieving the effect of sealing the slag discharge pipe 9, preventing the slurry in the cylinder 3 from being discharged from the slag discharge pipe 9.

[0037] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
