[0019] Optionally, a process of a papermaking sludge recycling system comprises the following steps:

[0020] 1) Separation: A large amount of sludge containing water is input into the separation and drainage tank through the input pipe port, where the sludge sinks and the sewage floats. Water is pumped out by the water pump, and the water passes through the water absorption plate and is directly sucked into the evaporator. After being heated by the heater in the evaporator, it evaporates and is input into the recovery pipeline. The first motor drives the screw propeller A to rotate, and the sludge is pumped out upward, and then the sludge passes through the output pipe port and enters the water absorption pump to complete the separation. The support frame can prevent the water absorption plate from contacting the sludge, extract the sludge, and has a lower limit. The screw propeller A can only transport the sludge. If there is no sludge and only sewage is left, the rapid movement of the sewage will flow back, and a large amount of sewage will not be discharged with the screw propeller A.

[0021] 2) Differentiation: Start the second motor to drive the bevel gear disc to rotate so that the inner processing tube rotates as a whole, and use the spiral heater to heat the inner processing tube as a whole, so as to evaporate and remove the water in the sludge; during the evaporation process of the sludge, it is transported backwards following the pushing capacity provided by the threaded pushing edge, and the evaporation is completed during this period. At the same time, the mud blocks at the rear are lifted by the lifting push plate and put into the collection channel. The threaded propeller B is driven to rotate by the third motor to transport the mud blocks backwards, and then the mud blocks fall into the separation bin and fall on the top of the conveyor belt for continuous output;

[0022] 3) Condensation: During differentiation, water vapor exists in the inner treatment tube. Start the fourth motor to drive the transmission wheel to rotate, and use the transmission wheel to drive the eccentric rod to rotate. The eccentric rod drives the control frame to reciprocate left and right, and the two groups of side pistons are extended and retracted respectively to produce a variable volume effect. When the side piston contracts, the air passes through the outer one-way valve and is discharged to the outside. When the side piston extends, the air passes through the inner one-way valve and is sucked into the side piston to suck out the water vapor in the inner treatment tube. During this period, the water vapor passes through the water collection channel and is intercepted and cooled by the water filter layer. Start the fifth motor to drive the pipe shaft to rotate the filter silo as a whole, generate centrifugal force to gather and throw out the water in the water filter layer, and the water enters the water outlet pipe and converges with the steam discharged from the evaporator. After contacting each other, they are cooled and condensed to gather into water, providing value for reuse.

[0023] The beneficial effects are as follows:

[0024] 1. The present invention is provided with an internal processing tube, and provides a reuse process for automatically processing sludge lumps. The internal processing tube is heated as a whole by a spiral heater, so that the water in the sludge can be directly evaporated and removed. The threaded pushing edge also provides a pushing ability to transport the sludge backwards. At the same time, the mud lumps at the rear are lifted by a lifting push plate and put into a collection channel. The mud lumps are transported backwards by a threaded pusher B, so that the sludge falls on the top of the conveyor belt and is continuously output, so that the sludge can be recovered and used to make black cards.

[0025] 2. A water collection channel is provided to provide the function of quickly collecting water vapor and condensing it into water. The water vapor is forced to pass through the water collection channel by negative pressure, and the water is intercepted and cooled by the water filter layer. The fifth motor drives the tube shaft to rotate the filter silo as a whole, generating centrifugal force to gather and throw out the water in the water filter layer. The water enters the water outlet pipe and converges with the steam discharged from the evaporator. After contacting each other, it is cooled, condensed and gathered into water for reuse, which saves costs and is environmentally friendly.

[0026] 3. A separation drainage bin is provided to provide a separation structure for rapid diversion of sludge and sewage. The separation drainage bin itself can settle, and the support frame can prevent the water suction disc from contacting the sludge so as to extract the sludge. A lower limit is provided to avoid extracting the sludge, while the screw propeller A can only transport the sludge. If there is no sludge but only sewage, the rapid movement of the sewage will flow back, and a large amount of sewage will not be discharged with the screw propeller A. The water suction disc floats on the water surface and can automatically adapt to the water level. BRIEF DESCRIPTION OF THE DRAWINGS

A process for a papermaking sludge recycling system as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: 1) Separation, a large amount of sludge containing water is input into the separation and drainage tank (1) through the input pipe opening (101), wherein the sludge sinks and the sewage floats, and water is pumped by the water pump (2), and the water passes through the water suction plate (107) and is directly sucked into the evaporator (3), and then evaporated after being heated by the heater in the evaporator (3), and then input into the recovery pipeline; the first motor (105) drives the screw propeller A (104) to rotate, and the sludge is pumped upward, and then the sludge passes through the output pipe opening (103) and enters the water pump (2), completing the separation; 2) Differentiation, start the second motor (508) to drive the bevel toothed disc (507) to rotate so that the inner processing tube (5) rotates as a whole, and at the same time, use the spiral heater (403) to heat the inner processing tube (5) as a whole, thereby evaporating and removing the water in the sludge; during the evaporation process of the sludge, the sludge is transported backwards following the pushing capacity provided by the threaded pushing edge (505), and the evaporation is completed during this period. At the same time, the rear mud blocks are lifted by the lifting push plate (504) and put into the collection channel (802), and the threaded propeller B (804) is driven to rotate by the third motor (803) to transport the mud blocks backwards, and then the mud blocks fall into the separation bin (7), and fall on the top of the conveyor belt (703) for continuous output; 3) Condensing gas. During the differentiation, water vapor exists in the inner processing tube (5). The fourth motor (14) is started to drive the transmission wheel (15) to rotate. The transmission wheel (15) drives the eccentric rod (1501) to rotate. The eccentric rod (1501) drives the control frame (12) to reciprocate left and right, and the two groups of side pistons (1001) are respectively extended and retracted to produce a variable volume effect. When the side piston (1001) contracts, air passes through the outer one-way valve (1003) and is discharged to the outside. When the side piston (1001) extends, air passes through the inner one-way valve (1002) and is sucked into the side piston (1001), and the water vapor in the inner processing tube (5) is sucked out. During this period, the water vapor passes through the water collection channel (9), and the water is intercepted and cooled by the water filter layer (904); The fifth motor (16) is started to drive the pipe shaft (903) to rotate, so that the filtering silo (902) rotates as a whole, generating centrifugal force to gather and throw out the water in the filter layer (904). The water enters the water outlet pipe (901) and converges with the steam discharged from the evaporator (3). After contacting each other, they are cooled and condensed to form water, which provides value for reuse.
