Description

Technical Field

[0001] The utility model relates to the technical field of paper pulp preparation, in particular to a raw material shore pretreatment device before paper pulping ships are transported by sea. Background Art

[0002] In the current pulp preparation methods, it is necessary to wait for the ship to deliver the required raw materials to the site before building a plant on land for pulping, which results in a long pulping process and high costs. In order to improve this problem, the pulp preparation process can be completed during the sea transportation of the ship, and the waste paper raw materials to be recycled can be transported to the dock. After the ship docks at the dock, the waste paper raw materials can be transported on board, and the pulp can be prepared during the sea transportation of the ship.

[0003] However, due to errors in the sailing time of the ship, sometimes the waste paper raw materials have been transported to the dock, but the ship has not arrived yet. Therefore, a waste paper pretreatment device is designed, which can use the time on the shore to pretreat the waste paper before pulping during the sea transportation of the ship. In the process of pretreating the waste cardboard, it is necessary to cut off the wire binding the waste paper package, and then crush the waste paper. However, in the process of cutting the wire, some small wires and iron filings will adhere to the cardboard and enter the crushing device together with the cardboard, which will damage the blades of the crushing device, and the mixed iron filings will also affect the subsequent process of further preparing pulp from the waste cardboard. Summary of the invention

[0004] The utility model overcomes the shortcomings of the prior art and provides a raw material shore pretreatment device before a pulping ship is shipped by sea.

[0005] In order to achieve the above purpose, a raw material shore pretreatment device before pulping ship is transported by sea is designed, including support frames arranged on left and right sides, a transmission rod is provided in the middle between the support frames on the left and right sides, one end of the transmission rod is connected to the driving motor, a number of crushing blades are evenly distributed on the transmission rod, a feed plate is provided above the transmission rod, a feed port is provided on the feed plate, magnet blocks are provided on the front and rear sides of the feed port respectively, metal detectors are provided on the inner sides of the left and right support frames, and a collection box is provided below the transmission rod.

[0006] The detection circle of the metal detector is located below the feed plate and above the crushing blade.

[0007] Limit blocks are distributed on the front and rear sides of the aggregate box.

[0008] The magnet block is in the shape of an elongated strip.

[0009] The upper ends of the support frames on the left and right sides are respectively connected to one end of the suction nozzle, and the other end of the suction nozzle is connected to the suction pump through a pipeline.

[0010] The support frame is provided with a mounting hole for the pipeline to pass through.

[0011] Support plates are respectively arranged on the outer sides of the support frames on the left and right sides.

[0012] Compared with the prior art, the utility model can use the time on the shore to pre-treat the waste paper before pulping during the sea transportation of the ship. It has a simple structure and is easy to disassemble and assemble. It can timely remove small iron wires, iron filings, etc. attached to the waste paperboard, and reduce the impact on the crushing device and subsequent processes. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is a top view of the feed plate of the utility model. DETAILED DESCRIPTION

[0015] The utility model is further described below with reference to the accompanying drawings. Example

[0016] like Figure 1 to Figure 2 As shown, a transmission rod 2 is provided in the middle between the support frames 1 on the left and right sides, one end of the transmission rod 2 is connected to a driving motor 3, a number of crushing blades 4 are evenly distributed on the transmission rod 2, a feed plate 5 is provided above the transmission rod 2, a feed port 6 is provided on the feed plate 5, magnet blocks 7 are provided on the front and rear sides of the feed port 6, metal detectors 10 are provided on the inner sides of the left and right support frames 1, and a collection box 8 is provided below the transmission rod 2.

[0017] The detection circle 14 of the metal detector 10 is located below the feed plate 5 and above the crushing blade 4. When in use, the metal detector 10 is a purchased part. The detection circle of the purchased metal detector 10 is aligned with the downward position of the waste cardboard to detect whether there is iron wire or iron filings attached to the waste cardboard entering the crushing blade 4.

[0018] Limit blocks 9 are provided on both sides of the front and rear of the aggregate box 8. Figure 1 As shown, the left and right sides of the material collection box 8 are in contact with the inner sides of the left and right support frames 1. The front and rear sides of the material collection box 8 are provided with limit blocks 9 to position the material collection box 8.

[0019] The magnet block 7 is in the shape of an elongated strip.

[0020] The upper ends of the support frames 1 on the left and right sides are respectively connected to one end of the suction nozzle 11, and the other end of the suction nozzle 11 is connected to the suction pump through the pipe 12. The support frame 1 is provided with a mounting hole for the pipe 12 to pass through. When in use, waste gas is generated during the waste cardboard crushing process. The suction pump, the pipe 12, and the suction nozzle 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.

[0021] Support plates 13 are respectively disposed on the outer sides of the support frames 1 on the left and right sides to play a supporting role.

[0022] Before using the present embodiment, 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 6, and the waste paperboard enters the crushing blade 4 from the feed port 6, and the driving motor 3 drives the crushing blade 4 to rotate through the transmission rod 2 to crush the waste paperboard. The crushed waste paperboard enters the collection box 8.

[0023] When the waste paperboard is located at the feed inlet 6, the magnet blocks 7 at both sides of the feed inlet will absorb the iron wire and iron filings adhered to the waste paperboard, thereby reducing the influence of the iron wire and iron filings on the subsequent crushing and pulping process.

[0024] When the present embodiment is used, the waste paper is waste corrugated cardboard, and the size of the feed opening 6 matches the size of the waste cardboard.

[0025] The utility model can pre-treat waste paper on the shore before pulping during the sea transportation of the ship. The utility model has a simple structure and is easy to disassemble and assemble. Small iron wires and iron filings attached to the waste paperboard can be removed in time, reducing the impact on the crushing device and subsequent processes.
