AI Technical Summary
Existing heater pipes are prone to scaling when the water quality is impure, resulting in low cleaning efficiency and inconvenience, requiring the pipes to be dismantled for manual cleaning.
A lead screw and guide rod are installed inside the main pipe of the heater. The lead screw is driven by an electric motor to rotate, which drives the connecting plate to move up and down inside the pipe. Combined with a ring scraper to remove scale, and a collection cylinder to collect scale and impurities, automatic cleaning is achieved.
No manual cleaning is required, which improves cleaning efficiency and safety, simplifies the limescale removal process, and enhances cleaning convenience.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heater pipe cleaning equipment, specifically a heater that facilitates pipe cleaning. Background Technology
[0002] The heat exchanger has two internal pipe loops: a heat source and a heated source. The heat source is like the flame in a water heater, producing hot water or steam. The heated source is like the water being heated in the water heater. In the heat source loop, there is a regulating valve before the heat source inlet of the heat exchanger; changing the opening of this valve adjusts the temperature of the heated source. Because water continuously flows within the main pipe of the heater's heated source, impurities in the water can easily cause scale buildup on the inner wall of the main pipe, affecting its performance. Current cleaning methods typically involve disassembling the pipes and manually cleaning them, which is inefficient and extremely inconvenient. Therefore, we propose a heater that facilitates pipe cleaning. Utility Model Content
[0003] The purpose of this invention is to provide a heater that facilitates pipe cleaning, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a heater for easy pipe cleaning, comprising a heater main pipe, a connecting flange at the top of the heater main pipe, a protective cover on the connecting flange, a motor inside the protective cover, a lead screw connected to the bottom of the motor, a guide rod parallel to the side of the lead screw, a connecting plate screwed onto the lead screw, a fixing plate on the outside of the connecting plate, a locking block installed in the groove on the outside of the fixing plate by bolts, a positioning block on the side of the locking block, an annular scraper installed on the outside of the positioning block, a connecting bolt movably connected to the fixing plate, and the bottom of the connecting bolt connected to a threaded hole on a collecting cylinder.
[0005] In the above scheme, an insulation layer is provided on the outside of the main pipe of the heater.
[0006] In the above scheme, the motor is connected to the power supply and the switch via wires.
[0007] In the above scheme, the connecting plate is provided with screw holes and round holes that cooperate with the lead screw and guide rod.
[0008] In the above scheme, the diameter of the collecting cylinder is smaller than the inner diameter of the main heating pipe, and a collecting cavity is opened inside the collecting cylinder.
[0009] In the above scheme, the outer side of the annular scraper is fitted with the inner wall of the heater main pipe, and the inner wall of the annular scraper is glued and fixed to the positioning block.
[0010] In the above scheme, the connecting flange is fixedly connected to the top of the heater main pipe by positioning bolts.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This type of heater, which facilitates pipe cleaning, has a simple and reasonable structural design and strong practicality. By setting a lead screw and a guide rod inside the main pipe of the heater, and using an electric motor as a drive mechanism to rotate the lead screw, the connecting plate can move stably up and down inside the main pipe of the heater under the limiting action of the guide rod. During this process, the scale adhering to the inner wall of the main pipe of the heater can be removed by the annular scraper, ensuring the performance of the main pipe of the heater itself. No manual cleaning is required, improving cleaning efficiency and safety. Furthermore, by setting a collection cylinder below the annular scraper as a scale collection device, the scale and impurities cleaned by the annular scraper can be collected for subsequent unified treatment, which is more convenient. Moreover, the collection cylinder and the fixing plate are connected by connecting bolts, which facilitates disassembly and cleaning. Attached Figure Description

By setting the lead screw 15 and guide rod 16 inside the heater main pipe 1, and using a motor 14 as a drive mechanism to drive the lead screw 15 to rotate, while the guide rod 16 limits its movement, the connecting plate 17 can move stably up and down inside the heater main pipe 1. During this process, the scale adhering to the inner wall of the heater main pipe 1 can be removed by the annular scraper 23, ensuring the performance of the heater main pipe 1 itself. No manual cleaning is required, improving cleaning efficiency and safety.

[0023] In the above scheme, the connecting flange 12 is fixedly connected to the top of the heater main pipe 1 by positioning bolts.
[0024] Working principle:
[0025] In this type of heater that facilitates pipe cleaning, the connecting flange 12 is first assembled on the top of the main pipe 1 of the heater. Then, the motor 14 drives the lead screw 15 to rotate. At the same time, under the limiting action of the guide rod 16, the connecting plate 17 can move stably up and down inside the main pipe 1 of the heater. During this process, the scale adhering to the inner wall of the main pipe 1 of the heater is removed by the annular scraper 23, ensuring the performance of the main pipe 1 of the heater itself. No manual cleaning is required, improving cleaning efficiency and safety. By setting a collection cylinder 25 below the annular scraper 23 as a scale collection device, the scale and impurities cleaned by the annular scraper 23 can be collected for subsequent unified treatment, which is more convenient. Furthermore, the collection cylinder 25 and the fixing plate 18 are connected by connecting bolts 24, which facilitates disassembly and cleaning, further improving the cleaning effect.
