Description

Technical Field

[0001] The utility model relates to the technical field of papermaking machines, in particular to a dehumidifying device for a wire portion of a papermaking machine. Background Art

[0002] Existing papermaking machines operate in two ways: dry and wet. Wet papermaking machines are divided into fourdrinier papermaking machines, sandwich papermaking machines, and inclined-wire papermaking machines. Currently, when Fourdrinier papermaking machines produce translucent or transparent paper, in order to improve the dehydration efficiency of the wire section and stabilize product quality, the pulp on the wire section must be heated and maintained at 65°C to 70°C. As a result, a large amount of water vapor is emitted into the workshop during the forming process of the high-temperature paper stock on the wire section, causing the on-site papermaking environment to always be in a harsh state of high temperature, high humidity, and low visibility. This has serious adverse effects on the safety of production operations, the safety and reliability of equipment electrical systems, and the stability of product quality. Therefore, a dehumidification device is needed to remove the water vapor.

[0003] In the existing dehumidification, the dehumidification device is set at the part to be dehumidified and fixed to the frame of the papermaking machine. It is large in size and has a small space between it and the papermaking machine. If the papermaking machine fails, the dehumidification device needs to be disassembled for maintenance. The operation is relatively troublesome and the work efficiency is low. In addition, when the existing dehumidification device is used, water vapor will condense into small water droplets and drip, causing damage to the paper, resulting in poor use effect. Utility Model Content

[0004] In order to solve the problems in the above background, the utility model provides a paper machine wire dehumidification device, which has the characteristics of simple operation, no need to disassemble the dehumidification device during maintenance, high working efficiency, and effective prevention of water droplets.

[0005] The utility model is implemented as follows: a paper machine wire dehumidification device comprises a bottom plate and a wire body, the wire body being arranged on the upper end surface of the bottom plate, the upper end surface of the bottom plate being fixedly connected to two symmetrically distributed support plates, the two support plates having opposite sides each having a T-shaped chute, the interiors of the two T-shaped chute each having a T-shaped slider slidably connected thereto, the opposite ends of the two T-shaped sliders being fixedly connected to a fixing plate, and the upper end surfaces of the two fixing plates being fixedly connected to a support frame;

[0006] The support frame is internally rotatably connected with a sliding rod and a screw, and the outer walls of the sliding rod and the screw are movably connected with a movable block, the lower end surface of the movable block is fixedly connected to a mounting plate through two symmetrically distributed connecting plates, the lower end surface of the mounting plate is fixedly connected to a flow guide cover, the upper end surface of the flow guide cover is connected to a connecting pipe extending to the top of the mounting plate, and a water collecting mechanism is provided below the flow guide cover;

[0007] A moisture removal mechanism is provided above the support frame.

[0008] In order to facilitate the safe discharge of water in the water collection tank, a paper machine mesh dehumidification device is preferably used in the present invention.

[0010] In order to drive the T-shaped slider to move up and down, as a preferred embodiment of the paper machine wire dehumidification device of the present invention, a hydraulic cylinder located below the T-shaped slider is installed inside the two T-shaped slides.

[0011] In order to drive the screw to rotate, as a preferred dehumidification device for a paper machine wire section of the present invention, a servo motor is installed on the right end face of the support frame, and the output end of the servo motor is fixedly connected to the screw.

[0012] In order to enable the air guide pipe to move with the movable block, as a preferred embodiment of the paper machine wire dehumidification device of the present invention, the air guide pipe is configured as a retractable hose.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

At the same time, the exhaust fan cooperates with the air guide pipe to extract air, so that the water vapor enters the connecting pipe through the air guide cover, and then is discharged from the exhaust pipe through the air guide pipe. The utility model has a smaller volume and is more convenient to use.

[0015] The water vapor is condensed into small water droplets through the deflector cover, and the water droplets flow down the inner wall of the deflector cover and into the water collection tank.
