[0004] Although the above patented technology can complete the pulping process, it involves too many devices, too much space, occupies a large area, and has low space utilization, which increases the cost and is not conducive to practical application. Summary of the invention

[0005] The purpose of the present invention is to solve the problems of excessive equipment in the pulping process, poor space utilization and low pulping efficiency in the prior art, and to propose an integrated equipment for pulping, grinding and washing.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An integrated equipment for pulp cooking, pulp grinding and pulp washing comprises a fixed base, characterized in that an outer cylinder is installed in the middle of the fixed base, a water inlet is provided on the side of the outer cylinder, a bottom cover of the outer cylinder is connected to the cylinder body through a flange, the bottom cover can be removed, and a variable speed motor is installed on the top of the fixed base.

[0008] The variable speed motor is connected to the transmission shaft, and the transmission shaft passes through the top cover of the outer cylinder to reach the inside of the outer cylinder and connects to the inner cylinder. The outer side of the bottom cover of the inner cylinder is engraved with a grinding disc pattern. The inner cylinder has an electric heating function, and the bottom cover of the inner cylinder has an opening.

[0009] Preferably, there is a conical grinding disc below the bottom cover of the inner cylinder, the size and shape of which match those of the bottom cover of the inner cylinder, and a positioning shaft is connected below the conical grinding disc, and the positioning shaft passes through the bottom cover of the outer cylinder.

[0010] Preferably, ordinary motor 1 and ordinary motor 2 are respectively fixed on both sides above the top cover of the outer cylinder, ordinary motor 1 is connected to transmission shaft 2, transmission shaft 2 passes through the top cover of the outer cylinder and enters the interior of the outer cylinder, transmission shaft 2 is connected to feeding screw 1, and there is a discharge port 1 with a valve below the feeding screw 1, and the discharge port 1 is located at the bottom cover of the outer cylinder, and a pulp screening net is fixed on the inner wall of the outer cylinder at a distance of 0.1 mm from the outer contour of the feeding screw 1.

[0011] Preferably, the ordinary motor 2 is connected to a transmission shaft 3, the transmission shaft 3 passes through the top cover of the outer cylinder and enters the interior of the outer cylinder, the transmission shaft 3 is connected to the feeding screw 2, and there is a discharge port 2 with a valve below the feeding screw 2, and the discharge port 2 is located at the bottom cover of the outer cylinder.

[0012] Compared with the prior art, the present invention provides an integrated equipment for pulp cooking, pulp refining and pulp washing, which has the following beneficial effects:

[0013] 1. The integrated pulp cooking, grinding and washing equipment controls the distance and relative motion state between the conical grinding disc and the inner cylinder by setting a positioning shaft and a positioning pin mechanism. When the inner cylinder and the conical grinding disc are completely fitted, the rotation of the inner cylinder can drive the conical grinding disc to rotate, so that the pulp inside the inner cylinder can be heated by rotation. When the distance between the inner cylinder and the conical grinding disc is pulled apart, the conical grinding disc is fixed to the outer cylinder by the positioning pin, and a gap appears between the bottom cover of the inner cylinder and the conical grinding disc, and relative rotation and friction occur. While the pulp is sprayed out from the opening of the bottom cover of the inner cylinder, it is ground by the bottom cover of the inner cylinder and the conical grinding disc, thereby improving the efficiency of pulp cooking and grinding. 2. The integrated pulp cooking, grinding and washing equipment controls the distance and relative motion state between the conical grinding disc and the inner cylinder by setting a pulp screening net and a feeding screw assembly. When the inner cylinder rotates, the pulp in the outer cylinder cavity is driven to move and adhere to the pulp screening net. The pulp attached to the pulp screening net is discharged from the discharge port by the feeding screw, thereby improving the efficiency of pulp washing.

[0014] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. The present invention improves the overall efficiency of pulping by quickly refining and washing the pulp after pulp boiling. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A positioning pin (12) is connected to the bottom of the conical grinding disc (11), and a positioning hole (13) is provided on the bottom cover of the outer cylinder (2);

[0031] An ordinary motor 1 (5) and an ordinary motor 2 (7) are fixed on both sides above the top cover of the outer cylinder (2), the ordinary motor 1 (5) is connected to a transmission shaft 2 (19), the transmission shaft 2 (19) passes through the top cover of the outer cylinder (2) and enters the interior of the outer cylinder (2), the transmission shaft 2 (19) is connected to a feeding screw 1 (15), a discharge port 1 (4) with a valve is provided below the feeding screw 1 (15), the discharge port 1 (4) is located at the bottom cover of the outer cylinder (2), and a pulp screening net (14) is fixed on the inner wall of the outer cylinder (2) at a distance of 0.1 mm from the outer contour of the feeding screw 1 (15);

[0032] The ordinary motor 2 (7) is connected to a transmission shaft 3 (18), and the transmission shaft 3 (18) passes through the top cover of the outer cylinder (2) and enters the interior of the outer cylinder (2). The transmission shaft 3 (18) is connected to the feeding screw 2 (8), and there is a discharge port 2 (16) with a valve below the feeding screw 2 (8), and the discharge port 2 (16) is located at the bottom cover of the outer cylinder (2).

[0033] When the present application is in use, the electrical components appearing in the application are all connected to an external power supply and a control device. First, the bottom cover of the outer cylinder 2 is removed, and the conical grinding disc 11 is removed at the same time. The mixture of pulping raw materials and liquid medicine (hereinafter collectively referred to as slurry) is injected into the inner cylinder 9 through the opening on the bottom cover 10 of the inner cylinder. The conical grinding disc 11 and the bottom cover of the outer cylinder 2 are installed back to their original positions. By adjusting the positioning shaft 3 upward, the conical grinding disc 11 is tightly combined with the bottom cover 10 of the inner cylinder. At this time, the variable speed motor 6 starts to rotate slowly, and the inner cylinder 9 is driven to rotate through the transmission shaft 17. The conical grinding disc 11 will also be statically rubbed. Under the action of friction, it rotates with the inner cylinder 9, and the inner cylinder 9 generates heat, so as to achieve the effect of rotating and heating the slurry. When the slurry fully reacts, the slurry cooking process is completed, the heating function is turned off, the conical grinding disc 11 is adjusted to rotate to a suitable angle, the positioning pin 12 is aligned with the positioning hole 13, the positioning shaft 3 is adjusted downward, the positioning pin 12 is inserted into the positioning hole 13, so that the conical grinding disc 11 no longer rotates with the inner cylinder 9, but is relatively stationary with the outer cylinder 2, at this time, a gap appears between the conical grinding disc 11 and the bottom cover 10 of the inner cylinder, the gap is adjusted to a suitable size, and the speed of the variable speed motor 6 is increased. At this time, the slurry will be ejected from the small holes on the bottom cover 10 of the inner cylinder 9 under the combined effect of its own gravity and the high-pressure gas inside the inner cylinder 9, and will be ground in the gap between the bottom cover 10 of the inner cylinder and the conical grinding disc 11. The ground slurry will flow into the cavity of the outer cylinder 2 to complete the grinding process. At this time, clean water is injected into the inner part of the outer cylinder 2 from the water inlet 20 to mix the clean water with the slurry. The slurry in the cavity of the outer cylinder 2 will be driven by the inner cylinder 9 and revolve around the inner cylinder 9. The rotation direction of the inner cylinder 9 needs to ensure that the slurry first passes through the feeding screw 15 and then passes through the slurry screening net 14 when it revolves around the inner cylinder 9. During this process, the fibers will adhere to the side of the pulp screen 14 close to the feeding screw 15. When all the fibers in the pulp are attached to the pulp screen 14, the pulp washing process is completed. At this time, the discharge port 16 is opened, the ordinary motor 7 is started, and the feeding screw 8 is driven to rotate through the transmission shaft 18 to discharge the waste liquid from the cavity of the outer cylinder 2. After the waste liquid is discharged, the discharge port 4 is opened, the ordinary motor 5 is started, and the feeding screw 15 is driven to rotate through the transmission shaft 19. The feeding screw 15 discharges the fibers attached to the pulp screen 14 out of the cavity of the outer cylinder 2 through the discharge port, completing the entire pulping process.
