Description

Technical Field

[0001] This utility model relates to the field of quartz heater technology, specifically to an anti-scaling structure for a quartz heater. Background Technology

[0002] In the daily process of heating water sources, electric heaters are more convenient and efficient to use, so they are currently favored by many users. An electric heater is a device that uses the Joule effect of electric current to convert electrical energy into heat energy to heat an object. It is usually divided into direct resistance heating and indirect resistance heating. In the former, the power supply voltage is directly applied to the object being heated, thereby causing the object to dissipate heat to the object being heated, thus achieving the purpose of heating.

[0003] Chinese patent document CN206366203U discloses a tube-type heater for preventing scaling. It includes a heater with heating tubes arranged axially along its interior. Each heating tube has an outlet at its upper end and an inlet at its lower end. A top cover is located above the heating tubes. A movable inner liner is fitted inside the heating tubes, comprising a bottom-sealed inner wall and an outer wall fitted over it. A flow-guiding cavity is formed between the inner and outer walls, and the bottom of the cavity communicates with the inlet. This invention solves the problem of low concentration efficiency caused by having to stop the machine and wait for cleaning to complete before restarting for concentration. Simultaneously, it ensures that the liquid is only contained within the cavity near the movable inner liner wall, resulting in a faster liquid heating rate and effectively improving the working efficiency of the concentration tank.

[0004] The existing technology mentioned above cannot perform rapid disassembly, cleaning, and descaling of the heater, nor can it perform rapid descaling of the inner wall of the heating tube. Therefore, it is necessary to develop an anti-scaling structure for quartz heaters. Utility Model Content

It has the advantages of tight and stable connection and convenient assembly and disassembly.

[0022] Furthermore, both the upper positioning sleeve 6 and the lower positioning sleeve 4 are provided with flanges 11. The valve sleeve 3 is fixed to the flanges 11 by limiting bolts 10, which can quickly limit the installation and alignment between the upper positioning sleeve 6 and the lower positioning sleeve 4 and the valve sleeve 3.

The surface of the rotating head 15 is connected to a descaling rod fixing sleeve 14 via a fixed shaft 16. The descaling rod fixing sleeve 14 and the descaling rod 13 are fixed by insertion. By turning on the servo motor 5, the rotating head 15 is driven to rotate, thereby further driving the descaling rod 13 to swing up and down, so that the descaling rod 13 can rub and brush off the dirt on the inner wall of the quartz heating tube 1.

The descaling rod fixing sleeve 14 and the descaling rod 13 are fixed by insertion. By turning on the servo motor 5, the rotating head 15 is driven to rotate, which in turn drives the descaling rod 13 to swing up and down, facilitating the friction and brushing of dirt off the inner wall of the quartz heating tube 1 by the descaling rod 13. A flange connector 2 is installed outside the quartz heating tube 1. An upper positioning sleeve 6 is detachably installed at the lower end of the flange connector 2, and a threaded joint 9 is provided at the lower end of the flange connector 2. The flange connector 2 is tightly screwed and fixed to the internal threaded groove of the upper positioning sleeve 6 via the threaded joint 9, which facilitates quick connection and alignment between the flange connector 2 and the upper positioning sleeve 6. It has the advantages of tight and stable connection and convenient assembly and disassembly. The lower end of the upper positioning sleeve 6 is connected to the lower positioning sleeve 4 via the valve sleeve 3. Both the upper positioning sleeve 6 and the lower positioning sleeve 4 are provided with flanges 11. The valve sleeve 3 is fixed to the flanges 11 by the limiting bolts 10, which can quickly limit the installation and alignment between the upper positioning sleeve 6 and the lower positioning sleeve 4 and the valve sleeve 3. By facilitating the assembly and alignment of the internal components of the quartz heater, it has the advantages of convenient and quick installation and disassembly, which facilitates the precise positioning, installation, disassembly, cleaning and descaling of the internal quartz heating tube 1.
