Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of water purification equipment, specifically relating to a constant temperature pre-filter for pipelines. Background Technology
[0002] In daily production, water supply pipes are crucial equipment in factories, and their unobstructed flow and sealing directly affect production efficiency. Especially during cold seasons, low temperatures can easily cause the water inside the pipes to freeze, leading to blockages and requiring maintenance shutdowns. This not only causes pipe malfunctions but also triggers a series of production losses, significantly impacting production. Therefore, factories need to take targeted measures in advance before the cold season to ensure the normal operation of equipment and production.
[0003] Currently, most water pipes in factory equipment are made of carbon steel or PVC, some of which are exposed outside the workshop, near ventilation openings, or in areas without insulation. Due to the low ambient temperature, the industrial water in these pipes gradually cools below freezing, causing it to freeze. The ice layer can clog the pipe's inner diameter, leading to a significant decrease in water flow. Simultaneously, industrial water in these pipes easily mixes with sediment, rust, and microorganisms, which tend to accumulate inside the pipes. Ice formation further slows the water flow, promoting impurity deposition and exacerbating the blockage, potentially even causing production interruptions. Utility Model Content
[0004] This invention provides a constant temperature pre-filter for pipelines to solve the problem that existing water pipes in factories are prone to blockage in cold environments, resulting in insufficient flow rate to meet usage requirements.
[0005] The technical solution of this utility model is: a constant temperature pre-filter for pipelines, including a cylinder, which is a hollow structure. The cylinder has an inlet and an outlet on both sides. The inlet is connected to multiple filter elements through a pipe. The bottom of the cylinder has a mounting base plate with multiple mounting seats. The filter elements are inserted into the mounting frame and a heating rod is provided inside the filter elements.
[0006] As a further improvement of this utility model, the inlet and outlet are provided with threaded quick-connect interfaces, which facilitates connection and disassembly with various water pipes.
[0007] As a further improvement of this utility model, the heating rod is a bimetallic strip temperature-controlled heating rod with quartz as the outer contact material and a bimetallic strip inside.
[0008] As a further improvement of this utility model, the filter element is made of PTFE, which has corrosion resistance and high temperature resistance.
[0009] The beneficial effects of this invention are as follows: This invention combines multiple filter elements and heating rods to achieve filtration by constructing a filtration zone within the cylinder. Relying on the high corrosiveness and high temperature resistance of the PTFE filter elements, it not only filters out tiny impurities such as mud, rust, and microorganisms from the pipes, ensuring that the filtration process is not easily corroded, but also simultaneously heats the filtered water, preventing freezing of industrial water and ensuring the smooth flow of water through the equipment. This invention has a simple structure, is safe and reliable, and can heat and maintain a constant temperature while automatically filtering impurities in the water, preventing freezing and blockage of the water pipes in cold environments. It greatly optimizes the industrial water environment and has strong applicability. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0013] like Figure 1-2 As shown, a constant temperature pre-filter for pipelines includes a cylinder 1, which is a hollow structure. The cylinder 1 has an inlet 6 and an outlet 7 on both sides. The inlet 6 is connected to multiple filter elements 3 through a pipe. The bottom of the cylinder 1 is provided with a mounting base plate 4, and multiple mounting seats 5 are provided on the mounting base plate 4. The filter elements 3 are inserted into the mounting seats 5, and a heating rod 2 is provided inside the filter elements 3.
[0014] The inlet 6 and outlet 7 are equipped with threaded quick-connect fittings for easy connection and disassembly with various water pipes.
[0015] In use, place cylinder 1 at the inlet of the equipment's water supply pipe. Connect inlet 6 to the industrial water pipe via a pipe, and simultaneously connect outlet 7 to the inlet of the equipment's water supply pipe via a pipe. Open the industrial water valve to allow industrial water to enter cylinder 1, pass through the inlet to filter element 3, and adsorb various tiny impurities such as silt and rust from the industrial water, purifying the water quality. After water begins to flow, turn on heating rod 2 to heat the water at the set temperature. The heated heating rod 2 will transfer its temperature to the industrial water injected into filter element 3, allowing filter element 3 to heat the filtered industrial water and prevent freezing in cold winters below 0°C. The filtered industrial water is discharged through outlet 7 and finally enters the equipment's water supply pipe. The filtered and heated industrial water is less likely to cause blockages in the pipe, ensuring the normal operation of the equipment's water supply pipe even in extreme environments.
[0016] Heating rod 2 uses a bimetallic strip temperature-controlled heating rod. After being powered on, it continuously heats the water. When the temperature reaches the set value, the bimetallic strip inside the heating rod 2 deforms according to its different coefficient of thermal expansion, causing the temperature control contacts inside the heating rod 2 to automatically open, thus controlling the temperature and achieving a heat preservation effect. Conversely, if the water cools too much, the bimetallic strip inside the heating rod 2 will also deform, causing the temperature control contacts inside the heating rod 2 to close. This alternating process keeps the industrial water at a constant temperature.
