Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a papermaking pulp board drying device. Background Technology

[0002] The papermaking process includes two steps: pulping and papermaking. Pulping involves turning wood into pulp that can be used for papermaking, while papermaking involves processing the pulp to produce paper suitable for various purposes.

[0003] For factories that combine pulping and papermaking, the wet pulp from the pulping process can be directly transported to the papermaking workshop for use by the papermaking section. However, paper mills without pulping equipment need to purchase pulp from pulp mills as raw materials for papermaking. In this case, the pulp mill needs to form the pulp into pulp boards, and then dewater, dry, roll, and package it to produce paper pulp boards with higher dryness, which are then sold to the paper mills.

[0004] Existing paddle drying equipment mostly involves conveying and drying paddles simultaneously via conveyor belts. The dried paddles still contain a large amount of moisture and require a long period of cooling, resulting in low processing efficiency and a need for improvement. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above difficulties and provide a paper pulp board drying device with high drying effect and high processing efficiency.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a paper pulp board drying device, including a drying cylinder, an inlet and outlet on one side of the drying cylinder, a sealing cover hinged to the inlet and outlet, a rotating device inside the drying cylinder, and a plurality of screen boxes that can accommodate pulp boards evenly arranged circumferentially on the rotating device.

[0009] The drying drum is connected to a pipe with an input end at the bottom of the drying drum and an output end at the top of the drying drum. A hot air blower and an air-water separator are connected to the pipe.

[0010] The screen box includes a box body mounted on a rotating device and a cover hinged to the opening of the box body. The box body is provided with a lock body that cooperates with the cover body.

[0011] As an improvement, the rotating device includes a motor located at the bottom of the drying cylinder, the output end of the motor extending into the drying cylinder and connected to a rotating shaft, a sleeve being fitted onto the rotating shaft, both ends of the sleeve being provided with circular plates, and several mounting plates for connecting the circular plates being evenly provided on the edges of the circular plates, with the screen box located on the mounting plates.

[0012] As an improvement, the rotating shaft is provided with a sleeve, and the sleeve is evenly provided with a number of fan blades.

[0013] As an improvement, the hot air blower is positioned near the bottom of the drying cylinder.

[0014] As an improvement, the sleeve is positioned near the bottom of the drying cylinder.

[0015] (III) Beneficial Effects

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. The rotating device can drive the paddles in the screen box to rotate. The hot air generated by the hot air blower enters the drying cylinder and comes into full contact with the paddles. After being transported through the pipeline, the hot air is separated and discharged by the air-water separator. After being reheated by the hot air blower, the paddles are continuously dried.

[0018] 2. The fan blades can turbulent the hot air entering the drying cylinder and push the hot air upward;

[0019] 3. After the hot air blower has finished drying the paddle, the heating function of the hot air blower is turned off, which can dissipate heat from the paddle, resulting in a good drying effect and high processing efficiency. Attached Figure Description

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] Example 1

[0027] Combined with appendix Figure 1-4 A paper pulp board drying device includes a drying cylinder 1. The drying cylinder 1 has an inlet and outlet 2 on one side, which facilitates the loading and unloading of pulp boards by personnel. A sealing cover 3 is hinged to the inlet and outlet 2. A rotating device 4 is provided inside the drying cylinder 1. The rotating device 4 has several screen boxes 5 that can accommodate pulp boards evenly arranged in the circumferential direction.

[0028] The drying cylinder 1 is connected to a pipe 6 with an input end located at the bottom of the drying cylinder 1 and an output end located at the top of the drying cylinder 1. A hot air blower 7 and an air-water separator 8 are connected to the pipe 6. The hot air blower 7 is located near the bottom of the drying cylinder 1.

[0029] Personnel place the paddles to be dried into the screen box 5, close the sealing cover 3, and turn on the rotating device 4, hot air blower 7 and air-water separator 8. The rotating device 4 drives the screen box 5 to rotate, and the hot air generated by the hot air blower 7 enters the drying cylinder 1, taking away the moisture on the paddles. After being transported through the pipe 6, the water in the hot air is discharged to the outside by the air-water separator 8. The hot air is heated by the hot air blower 7 and then re-enters the drying cylinder 1 to dry the paddles.

[0030] After drying is complete, turn off the heating function of hot air blower 7. The air blown out by hot air blower 7 can cool down the paddle.

[0031] Example 2

[0032] Combined with appendix Figure 4 The screen box 5 includes a box body 9 mounted on the rotating device 4 and a cover 10 hinged to the opening of the box body 9.
