AI Technical Summary
The pulp pipes and white water discharge pipes in paper mills are prone to blockage in the bent pipe part, resulting in a decrease in circulation capacity or complete blockage, and it is difficult to clean, which increases labor intensity.
A bent pipe cleaning structure for paper mills is designed, including bent pipes, gate valves and high pressure cleaning devices. The high-pressure cleaning device enters the pipeline through the installation hole and uses high-pressure gas or high-pressure water flow to clear the blockage. The angle between the spear head and the horizontal section of the bend pipe is 45°-75°. In addition, the arc-shaped section is equipped with a visual cleaning window as a spare cleaning port.
The high-pressure cleaning device effectively unblocks at the bends, improving the efficiency of pulp and white water transmission, reducing labor intensity, and providing a visual cleaning window for regular inspections and backup cleaning.

Abstract
Description
Technical Field
[0001] The utility model relates to a cleaning structure, in particular to a curved pipe cleaning structure used in a paper mill. Background Art
[0002] In the modern papermaking industry, the transportation and processing of pulp is one of the key links in the production process, which is directly related to production efficiency, product quality and environmental protection. As an important facility connecting raw material preparation, pulping, papermaking and other processes, the smooth operation of pulp pipelines is crucial to maintaining the stability of the entire production line. However, with the continuous expansion of production scale and the improvement of production efficiency, the problem of pulp pipeline blockage has become increasingly prominent, becoming a major bottleneck restricting the efficient operation of paper mills. At the same time, the discharge and treatment of white water (mainly containing fine fibers, fillers, chemical additives and aqueous solutions of soluble substances) generated by paper mills during the production process is also an important task. The reasons for the blockage of white water discharge pipelines are similar to those of pulp pipelines, mainly due to the accumulation of suspended matter, colloidal substances and chemical precipitates. These substances gradually deposit in the pipelines to form a scale layer that is difficult to remove, resulting in a decrease in the pipeline's flow capacity, and even complete blockage in severe cases.
[0003] Due to the influence of the medium and resistance, the elbow part is prone to blockage and difficult to clean, causing many problems. For example, the pulp storage tank or the white water tank discharge pipe under the net for producing household paper in the paper mill is designed as a bend pipe. Due to the high pulp concentration, it is often blocked at the bend. However, due to the difficulty of using tools at the bend, the valve can only be disassembled for cleaning, which greatly increases the labor intensity. Utility Model Content
[0004] Purpose of the utility model: The purpose of the utility model is to provide a curved pipe cleaning structure for a paper mill.
[0005] Technical solution: The utility model discloses a curved pipe cleaning structure for a paper mill, comprising a curved pipe, a gate valve and a high-pressure cleaning device. The curved pipe comprises a horizontal section, an arc section and a vertical section. The gate valve is located between the horizontal section and the arc section. A mounting hole is provided through the arc section. A mounting portion is provided at the mounting hole. The high-pressure cleaning device can be detached from the mounting portion. The gun head of the high-pressure cleaning device passes through the mounting hole, and the length of the gun head located in the pipeline is 1-3 cm.
[0006] Furthermore, the high-pressure cleaning device is a cleaning device using high-pressure gas or high-pressure water flow, which utilizes high-pressure gas or high-pressure water flow to clear the blockage at the bend.
[0007] Furthermore, the angle between the gun head of the high-pressure cleaning device and the horizontal section of the curved pipe is 45°-75°.
[0008] Furthermore, the mounting portion also includes a sealing portion, which can seal the mounting opening after the high-pressure cleaning device is disassembled.
[0009] Furthermore, the arc segment also has a visible cleaning window.
[0010] Furthermore, the visible cleaning window is rotatably mounted on the arc section, and the width and height of the visible cleaning window are both less than one third of the diameter of the curved pipe.
[0011] Furthermore, a sealing ring is provided around the visible cleaning window.
[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. The utility model solves the problem of easy blockage at the bends of slurry transmission and waste slurry water by arranging a high-pressure cleaning device at the bends; 2. The visual cleaning window can be used to regularly check the condition of the bends, and can also be used as a backup cleaning port. When the high-pressure cleaning device cannot clean the blockage of the bends, the visual cleaning window can be used to intervene and clean. BRIEF DESCRIPTION OF THE DRAWINGS
