Abstract
Description
Technical Field
[0001] This utility model application relates to the field of pipeline heater technology, specifically a hot and cold water alternating instantaneous pipeline heater. Background Technology
[0002] Pipeline heaters are energy-saving devices that preheat materials. Installed before the material, they directly heat the material, allowing it to circulate and heat at high temperatures, ultimately saving energy. They are widely used for preheating heavy oil, asphalt, and light oil, among other fuel oils. A pipeline heater consists of two parts: the main body and the control system. The heating element uses a stainless steel pipe as a protective sleeve, high-temperature resistance alloy wire, and crystalline magnesium oxide powder, formed through a compression process. The control system employs advanced digital circuits, integrated circuit triggers, and high-reverse-voltage thyristors to form an adjustable temperature measurement and constant-temperature system, ensuring the normal operation of the electric heater.
[0003] Traditional instantaneous pipe heaters tend to accumulate scale on the surface of the heating tubes during use. This not only affects heating efficiency but may also reduce water quality, causing inconvenience to users. Existing cleaning methods mainly involve disassembly and cleaning, but these methods are often cumbersome and inefficient. Therefore, how to remove scale from the heating tubes simply and efficiently has become a pressing technical problem to be solved. Summary of the Invention
[0004] To address the problem that scale easily accumulates on the surface of heating pipes in traditional instantaneous pipe heaters during use, which not only affects heating efficiency but may also reduce water quality and cause inconvenience to users, existing cleaning methods mainly involve disassembly and cleaning, but these methods are often cumbersome and inefficient. This invention provides a hot and cold water alternating instantaneous pipe heater to solve the above problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A hot and cold water alternating instantaneous pipe heater includes a pipe heater body, an inlet port on the upper outer side of the pipe heater body, a drain port on the lower outer side of the pipe heater body, a heating tube body inside the pipe heater body, a servo motor fixed to one end of the pipe heater body, a lead screw fixed inside the pipe heater body extending from the output end of the servo motor, the end of the lead screw away from the servo motor being rotatably connected to the pipe heater body, a first cleaning ring slidably connected inside the pipe heater body, a second cleaning ring fixed inside the first cleaning ring that matches the shape and number of the heating tube body, and a movable plate fixed to the end of several second cleaning rings away from the first cleaning ring, the movable plate being threadedly connected to the lead screw.
[0007] Furthermore, a filter box is fixedly connected to the bottom of the drain outlet, a drain pipe is fixedly connected to the bottom of the filter box, a filter screen is fixed to the bottom of the filter box near the drain pipe, and a discharge device is provided at one end of the filter box.
[0008] Furthermore, the outer side of the first cleaning ring is in contact with the inner side of the pipe heater body, and both sides of the first cleaning ring are provided with inwardly inclined slopes.
[0009] Furthermore, the movable plate is shaped like a cross with a number of second cleaning rings, and the second cleaning rings are detachably fixed to the outer side of the movable plate by fixing bolts.
[0010] Furthermore, the discharge device includes a sealing door, the bottom end of which is rotatably connected to the filter box, and the top surface of which is fixedly connected to the filter box by fixing screws.
[0011] Furthermore, a sealing baffle is fixed inside the filter box near the sealing door, the sealing door fits against the sealing baffle, and an observation window is provided on the sealing door.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this utility model, a first cleaning ring is set inside the main body of the pipeline heater, and a second cleaning ring is fixed inside the first cleaning ring. At the same time, a servo motor drives the lead screw to rotate, which in turn drives the moving plate to move. The moving plate then drives the second cleaning ring and the first cleaning ring to move, so that the first cleaning ring and the second cleaning ring scrape off the scale inside the heater and on the heating tube respectively. This solves the problem that scale easily accumulates on the surface of the heating tube during the use of traditional instantaneous pipeline heaters. This not only affects the heating efficiency but may also reduce water quality and cause inconvenience to users. Existing cleaning methods mainly involve disassembly and cleaning, but these methods are often cumbersome and inefficient.
[0014] 2. In this utility model, a filter box is fixed at the bottom of the drain outlet, and a drain pipe is connected to the bottom of the filter box. At the same time, a filter screen is installed inside the filter box, so that when the water flows out through the drain outlet, the water containing impurities such as scale is filtered through the filter screen, and clean water is discharged through the drain pipe. When a lot of scale accumulates inside the filter box, the scale inside the filter box can be cleaned by opening the sealed door. Attached Figure Description

Detailed Implementation
[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A hot and cold water alternating instantaneous pipe heater includes a pipe heater body 1, a water inlet 2 on the upper outer side of the pipe heater body 1, a drain outlet 3 on the lower outer side of the pipe heater body 1, a heating tube body 4 inside the pipe heater body 1, a servo motor 5 fixed to one end of the pipe heater body 1, a lead screw 6 fixed inside the pipe heater body 1 at the output end of the servo motor 5, the end of the lead screw 6 away from the servo motor 5 being rotatably connected to the pipe heater body 1, a first cleaning ring 7 slidably connected inside the pipe heater body 1, a second cleaning ring 8 fixed inside the first cleaning ring 7 matching the shape and number of the heating tube body 4, a movable plate 9 fixed to the end of several second cleaning rings 8 away from the first cleaning ring 7, the movable plate 9 being threadedly connected to the lead screw 6, so that the first cleaning ring 7 and the second cleaning ring 8 scrape off scale from the inner wall of the pipe heater body 1 and the heating tube body 4.
[0023] Specifically, the outer side of the first cleaning ring 7 is in contact with the inner side of the pipe heater body 1. Both sides of the first cleaning ring 7 are provided with inwardly inclined slopes. The shape of the moving plate 9 is a cross shape that matches the number of the second cleaning rings 8. The second cleaning rings 8 are detachably fixed to the outer side of the moving plate 9 by fixing bolts, which makes it convenient to separate the second cleaning rings 8 and the moving plate 9.
[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a filter box 10 is fixedly connected to the bottom of the drain outlet 3, and a drain pipe 11 is fixedly connected to the bottom of the filter box 10. A filter screen 12 is fixed to the bottom of the filter box 10 near the drain pipe 11. A discharge device is provided at one end of the filter box 10 so that scale can be discharged through the drain outlet 3.
[0025] Specifically, the discharge device includes a sealing door 13, the bottom of which is rotatably connected to the filter box 10, and the top surface of the sealing door 13 is fixedly connected to the filter box 10 by fixing screws. A sealing baffle 14 is fixed inside the filter box 10 near the sealing door 13, and the sealing door 13 fits against the sealing baffle 14. An observation window 15 is provided on the sealing door 13, so that the scale inside the filter box 10 can be cleaned by opening the sealing door 13.
[0026] Working principle: When there is a lot of scale inside the main body 1 of the pipeline heater and on the main body 4 of the heating tube, the servo motor 5 is started, which drives the lead screw 6 to rotate. Then the lead screw 6 drives the moving plate 9 to move. At the same time, the moving plate 9 drives the second cleaning ring 8 to move. The movement of the second cleaning ring 8 drives the first cleaning ring 7 to move. Thus, the second cleaning ring 8 scrapes off the scale on the main body 4 of the heating tube, and the first cleaning ring 7 scrapes off the scale on the inner wall of the main body 1 of the pipeline heater. At the same time, when the first cleaning ring 7 moves, it pushes the scale into the filter box 10 through the drain port 3. When the water with scale enters the filter box 10, the filter screen 12 filters the scale, so that the clean water is discharged through the drain pipe 11. When there is a lot of scale inside the filter box 10, the operator can open the sealing door 13 by loosening the fixing screw, so that the operator can clean the scale inside the filter box 10.
