[0036] The pretreatment device includes a support frame 1-1 arranged on the left and right sides, a transmission rod 1-2 is arranged in the middle between the support frames 1-1 on the left and right sides, one end of the transmission rod 1-2 is connected to a driving motor 1-3, a plurality of crushing blades 1-4 are evenly distributed on the transmission rod 1-2, a feed plate 1-5 is arranged above the transmission rod 1-2, a feed port 1-6 is arranged on the feed plate 1-5, magnet blocks 1-7 are arranged on the front and rear sides of the feed port 1-6, metal detectors 1-10 are arranged on the inner sides of the support frames 1-1 on the left and right sides, and a collection box 1-8 is arranged below the transmission rod 1-2. The detection circle 1-14 of the metal detector 1-10 is located below the feed plate 1-5 and above the crushing blade 1-4. When used specifically, the metal detector 1-10 is a purchased part, and the detection circle of the purchased metal detector 1-10 is aligned with the downward position of the waste cardboard to detect whether there is still iron wire or iron filings adhered to the waste cardboard entering the crushing blade 1-4.

[0037] Limiting blocks 1-9 are provided on both sides of the front and rear of the aggregate box 1-8. Figure 1 As shown, the left and right sides of the material collection box 1-8 are in contact with the inner sides of the left and right support frames 1-1. The front and rear sides of the material collection box 1-8 are provided with limit blocks 1-9 to position the material collection box 1-8.

[0038] The magnet block 1-7 is in the shape of a long strip.

[0039] The upper ends of the support frames 1-1 on the left and right sides are respectively connected to one end of the suction nozzle 1-11, and the other end of the suction nozzle 1-11 is connected to the suction pump through the pipe 1-12. The support frame 1-1 is provided with a mounting hole for the pipe 1-12 to pass through. When in use, waste gas is generated during the waste cardboard crushing process. The suction pump, the pipe 1-12, and the suction nozzle 1-11 cooperate to collect the generated waste gas, which is then uniformly processed to reduce the impact on the environment and improve environmental protection performance.

[0040] Support plates 1-13 are respectively provided on the outer sides of the support frames 1-1 on the left and right sides to play a supporting role.

[0041] Before the pretreatment device is used, the wires on the bundled waste paper packages are cut off by a wire cutter, and then the waste paperboard is fed into the feed port 1-6, and the waste paperboard enters the crushing blade 1-4 from the feed port 1-6, and the driving motor 1-3 drives the crushing blade 1-4 to rotate through the transmission rod 1-2 to crush the waste paperboard. The crushed waste paperboard enters the collecting box 1-8. When the waste paperboard is located at the feed port 1-6, the magnet blocks 1-7 on the front and rear sides of the feed port absorb the wires and iron filings adhered to the waste paperboard, thereby reducing the influence of the wires and iron filings on the subsequent crushing and pulping processes.

[0042] When this embodiment is used, waste paper is waste corrugated cardboard, and the size of the feed port 1-6 matches the size of the waste cardboard. The pretreatment device can pretreatment the waste paper at the shore before pulping during the ship's sea transportation. The structure is simple and easy to disassemble and assemble, and small iron wires, iron filings, etc. attached to the waste cardboard are removed in time to reduce the impact on the crushing device and subsequent processes.

[0043] The raw material loading device comprises a conveyor belt 2-1, the end of which is connected to the ship, a cardboard cutting device 2-2 is provided at the head end of the conveyor belt 2-1, and a transition plate 2-3 arranged obliquely is provided at the end of the cardboard cutting device 2-2. A transport vehicle 2-4 is provided on the conveyor belt 2-1, and the cardboard cutting device 2-2 comprises a cutting table 2-2-1, a cardboard conveyor belt 2-2-2, a cutting blade 2-2-3, and a top plate 2-2-6. The front end of the transport vehicle 2-4 is provided with a cutting table 2 -2-1, a cardboard conveyor belt 2-2-2 is provided on the cutting table 2-2-1, a cutting blade 2-2-3 is provided above the cardboard conveyor belt 2-2-2, one end of the cutting blade 2-2-3 is connected to one end of a connecting rod 2-2-4, the other end of the connecting rod 2-2-4 is connected to one end of a lifting cylinder 2-2-5, the other end of the lifting cylinder 2-2-5 is fixed to the lower end of the top plate 2-2-6, and the center of the cutting blade 2-2-3 is connected to a rotating motor 2-2-8 through a transmission rod 2-2-7.

[0044] One side of the lower end of the top plate 2-2-6 is connected to the pressing cylinder 2-2-9. When the cutting blade 2-2-3 cuts the waste cardboard, the pressing cylinder 2-2-9 presses the waste cardboard to prevent the waste cardboard from deflecting.

[0045] A baffle is provided on the outside of the transition plate 2-3 to prevent the cut paper strips and paper pieces from falling from the side of the transition plate 2-3. One end of the transition plate 2-3 is connected to the cutting table 2-2-1, and the other end of the transition plate 2-3 is in contact with or separated from the transport vehicle 2-4.

[0046] The height of the cutting table 2-2-1 is higher than the upper end of the transport vehicle 2-4, ensuring that the cut paper strips and paper pieces enter the transport vehicle 2-4 under the action of gravity. A plurality of support rods 2-2-10 are arranged at the lower end of the cutting table 2-2-1 to play a supporting role.

[0047] The transport vehicle 2-4 includes a base 2-4-1, a material frame 2-4-2, a bracket 2-4-3, a turning frame 2-4-4 and wheels 2-4-5. Brackets 2-4-3 are respectively provided on the left and right sides of the upper end of the base 2-4-1. The inner side of the bracket 2-4-3 is connected to the turning frame 2-4-4. A material frame 2-4-2 is provided between the turning frames 2-4-4 on the left and right sides. A turning motor is connected to one side of the turning frame 2-4-4.

[0048] The conveyor belt 2-1 is provided with tracks that match the structure of the transport vehicle wheels 2-4-5, so as to facilitate the transport vehicle 2-4 to be transported on the conveyor belt 2-1.

[0049] When the raw material loading device is used, the cardboard is placed on the cardboard conveyor belt 2-2-2, and the cardboard conveyor belt 2-2-2 drives the cardboard to move under the cutting blade 2-2-3. The cutting blade 2-2-3 cuts the cardboard and cuts the whole piece of waste cardboard into several pieces or strips. The cut pieces and strips enter the transport vehicle 2-4 through the transition plate 2-3. After the transport vehicle 2-4 is full of paper strips and cardboard, it is transported to the end of the conveyor belt 2-1 under the action of the conveyor belt 2-1. The end of the conveyor belt 2-1 is located in the ship, and then the flip motor drives the flip frame 2-4-4 to flip, and the paper pieces and cardboard in the transport vehicle are dumped into the ship, completing the transportation of waste paper raw materials onto the ship.

[0050] When in use, the lifting cylinder 2-2-5 drives the cutting blade 2-2-3 to move up and down to a suitable position, and the rotating motor 2-2-8 drives the cutting blade 2-2-3 to rotate through the transmission rod 2-2-7, thereby cutting the waste cardboard. The number of cutting blades 2-2-3 is determined according to the size of the waste cardboard to be cut.

[0051] The raw material loading device will first cut the larger cardboard, and then transport the cut paper pieces onto the ship through a transport cart. The cut paper pieces are smaller in size, making full use of the transportation space of the transport cart, and the cut paper pieces are convenient for further preparation of pulp from subsequent waste paper raw materials.

[0052] The waste paper processing device includes a crushing device 3-1, a slag removal device 3-2, and a screening device 3-3. A waste paper feed port 3-4 is provided at the upper end of the crushing device 3-1, a water inlet 3-5 is provided on the side of the crushing device 3-1, and a discharge port 3-6 is provided at the other end of the crushing device 3-1.

[0053] A return pipe 3-13 is provided on one side of the recovery barrel 3-8, and both ends of the return pipe 3-13 are connected to the recovery barrel 3-8 respectively. A water pump is provided on the return pipe 3-13. When in use, the waste in the recovery barrel 3-8 passes through the spiral rod 3-9 and the filter element for many times through the cooperation of the water pump and the return pipe 3-13, so as to fully recover the pulp fibers in the waste. The shape of the return pipe 13-3 is U-shaped.

[0054] A stirring blade 3-14 is provided in the waste water cylinder 3-11, and one end of the stirring blade 3-14 is connected to a stirring motor 3-15 to fully stir the waste water and the purification solution.

[0055] The lower end of the crushing device 3-1 is provided with a residual material outlet 3-16. When in use, the residual material remaining in the crushing device 3-1 is cleared out from the residual material outlet 3-16 and then injected into the waste paper feed port 3-4 for re-operation, thereby improving the utilization rate of waste paper.

[0056] One end of the screw rod 3-9 is connected to a rotating motor.

[0057] When the waste paper treatment device is used, the waste paper raw material is sent from the waste paper feed port 3-4 to the crushing device 3-1 for crushing, and the water inlet 3-5 is connected to the water source, and water is added to the crushing device. The crushed waste paper is mixed with water and then enters the slag removal device 3-2 for slag removal. After the slag removal is completed, the mixture enters the screening device 3-3 for coarse screening and fine screening. The screening device 3-3 is provided with a pulp outlet, and the pulp outlet is connected to the stirring device for further pulp mixing. The waste outlet 3-7 of the screening device 3-3 is connected to the recovery cylinder. The waste entering the recovery cylinder passes through the spiral rod 3-9 and then enters the waste water cylinder 3-11 through the recovery pipe 3-10. Waste water treatment liquid is added to the waste water cylinder 3-11 to purify the waste water. The purified waste water is then uniformly recovered to the centralized waste water treatment place of the ship to wait for centralized treatment.

[0058] When the waste material passes through the spiral rod 3-9, the pulp fibers in the waste material are intercepted by the filter element. When the filter element intercepts a certain amount of pulp fibers, the filter element is removed to recover the pulp fibers, thereby improving the utilization rate of the waste material.

A temperature sensor 5-8 is provided in the cavity 5-5, and the temperature sensor 5-8 is connected to the controller 5-9; the cold end 5-7-1 of the semiconductor refrigeration plate 5-7 is connected to the heat conducting plate 5-12, and the heat conducting plate 5-12 extends into the cavity 5-5; the box body 5-1 and the box cover 5-2 are provided with a heat preservation layer; a ventilation hole 5-13 is provided on one side of the chassis 5-6; the controller 5-9 and the battery 5-10 are installed on the side of the chassis 5-6 away from the box body 5-1.

[0067] When the culture storage device is in use, the test tube 5-14 containing the culture sealed with liquid paraffin is placed in the test tube storage slot 5-4, and then the box cover 5-2 is closed and the entire storage device is placed in the refrigerator of the ship and connected to the external power supply 5-11. The entire storage device is kept in a low-temperature state through the refrigeration of the refrigerator, the temperature sensor 5-8 detects the temperature of the cooling medium in real time, and the battery 5-10 is kept in a fully charged state.

[0068] The insulation layer of the box body 5-1 and the box cover 5-2 can be a vacuum structure or a foamed material, which can play a role in heat buffering. When the temperature outside the box body 5-1 is constant, the temperature inside the box body 5-1 also tends to be constant; when the temperature outside the box body 5-1 changes, the temperature inside the box body 5-1 will not change too quickly.

[0069] When the whole ship loses power and the temperature rises, the heat is transferred to the box 5-1, and the cold storage medium first absorbs the heat and the temperature rises. Then, when the temperature sensor 5-8 detects that the temperature has risen to the critical value, the semiconductor refrigeration plate 5-7 is turned on, and the temperature of the entire cooling medium is lowered through heat conduction through the heat conduction plate 5-12, thereby ensuring that the bacteria are kept in a low temperature state, and the heat in the chassis 5-6 is dissipated through the ventilation holes 5-13.

[0070] The culture storage device can maintain a low temperature for a certain period of time after a power outage by setting a cold storage medium inside the device. If the temperature rises, the battery can be used as a power source to start the semiconductor refrigeration sheet to cool the cold storage medium, thereby ensuring that the culture is kept in a low temperature state for a long time.

The lifting motor 7-2-1 drives the screw rod 7-2-2 to rotate, and the screw rod 7-2-2 and the nut 7-2-3 fixed to the external structure rotate relative to each other to realize the lifting and lowering of the lifting column 7-2. The external structure can be a fixed structure such as a fixed bracket or a top plate of a fermentation bin, or a stable moving structure such as a crane.

[0073] The bio-enzyme liquid tank 7-1 is fixed on the external structure outside the lifting column 7-2.

The rotary joint 7-4 prevents the hose 7-2 from rotating with the rotating shaft of the hollow shaft motor 7-5. After the bio-enzyme injection is completed, the hollow shaft motor 7-5 stops rotating, the liquid outlet of the bio-enzyme liquid tank 7-1 is closed, and the lifting column 7-2 rises to retract the liquid outlet rod 7-9.

[0078] The bio-enzyme injection device inserts the liquid discharge rod into the paper pile through the lifting column, and rotates and stirs the liquid discharge rod while discharging liquid through the rotating motor, so that the bio-enzyme liquid is evenly injected into the waste paper pile to ferment the waste paper.
