Description

Technical Field

[0001] This utility model relates to the field of fluid electric heater technology, and in particular to a high temperature and high pressure fluid electric heater. Background Technology

[0002] High-temperature and high-pressure fluid electric heaters are key equipment widely used in chemical, petroleum, and power industries. Their main function is to heat fluid media to a high-temperature and high-pressure state using electrical energy to meet production process requirements. With the continuous development of industrial technology, higher requirements have been placed on the efficiency, stability, and cleanliness of electric heaters. In traditional electric heaters, impurities in the fluid media tend to accumulate on the inner wall of the heating tank during long-term operation, which not only affects heat transfer efficiency but also easily leads to equipment failure. Therefore, achieving efficient cleaning and convenient maintenance has become one of the core challenges in designing high-temperature and high-pressure fluid electric heaters.

[0003] Currently, traditional high-temperature and high-pressure fluid electric heaters mostly adopt a combination of fixed heating elements and static tank structures. The heating tank usually has electric heating tubes or heating wires arranged inside, which heat the fluid through direct contact or indirect conduction. The tank design is mostly closed, and the medium circulation is achieved only through the fluid inlet and outlet.

[0004] In traditional electric heaters, impurities in the fluid medium gradually adhere to the inner wall of the heating tank during long-term operation, forming a stubborn deposit layer. These deposits not only hinder heat conduction and reduce heating efficiency, but also shorten the equipment life due to local overheating. Because the tank structure is closed and lacks an efficient cleaning mechanism, the cleaning process requires frequent disassembly, which is not only cumbersome, but also seriously affects the stability of equipment operation and the sustainability of heating efficiency. Therefore, a high-temperature and high-pressure fluid electric heater is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-temperature and high-pressure fluid electric heater, which aims to improve the problem in the prior art where impurities in the fluid medium gradually adhere to the inner wall of the heating tank, forming a stubborn deposit layer. These deposits not only hinder heat conduction but also reduce heating efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature and high-pressure fluid electric heater includes a support column, a heating tank fixedly connected to the top of the support column, a heater body disposed inside the heating tank, an injection port disposed at the top of the heating tank, an outlet disposed at the bottom of the heating tank, a motor fixedly connected to the side wall of the heating tank, a disc fixedly connected to the output end of the motor, and a cleaning component disposed inside the disc. The cleaning component includes a scraper, one end of which is fixedly connected to the inside of the first disc, one side of which is slidably connected to the inner wall of the heating tank, and the other end of which is slidably connected to the second disc. The second disc is fixedly connected to the inside of the heating tank, and a fixing frame is fixedly connected to the side wall of the heating tank. A disassembly component is provided inside the fixing frame.

[0007] As a further description of the above technical solution: The disassembly assembly includes a sliding frame that is slidably connected inside the fixed frame.

[0008] As a further description of the above technical solution: A pressing handle is fixedly connected to the side wall of the sliding frame, a connecting frame is slidably connected to the outer wall of the fixed frame, and the heater body is fixedly connected inside the connecting frame.

[0009] As a further description of the above technical solution: The pressing handle is slidably connected inside the sliding frame, and the inner wall of the connecting frame is in contact with the outer wall of the heating tank.

[0010] As a further description of the above technical solution: A locking post is fixedly connected to the side wall of the sliding frame, and the locking post is slidably connected inside the connecting frame.

[0011] As a further description of the above technical solution: A locking pin is fixedly connected to the side wall of the locking post, and the outer wall of the locking pin engages with the inner wall of the connecting frame.

[0012] As a further description of the above technical solution: A spring is provided inside the sliding frame. One end of the spring is fixedly connected to the inner wall of the sliding frame, and the other end of the sliding frame is fixedly connected to the inner wall of the fixed frame.

[0013] This utility model has the following beneficial effects: 1. In this utility model, a motor drives a first disc to rotate, and the first disc drives a scraper to slide on the inner wall of the heating tank. The other end of the scraper slides synchronously on a second disc, thereby enabling the scraper to thoroughly scrape away residual impurities on the inner wall of the heating tank, thus achieving a highly efficient cleaning effect inside the heating tank. This solves the problems of difficult internal cleaning of traditional electric heaters and the impact of impurity accumulation on heating efficiency, and improves the stability of equipment operation and the durability of heating efficiency.

[0014] 2. In this utility model, the sliding frame is driven to slide within the fixed frame by pressing the handle. The sliding frame drives the locking pin and locking pin to disengage from the inner wall of the connecting frame. When operating in the reverse direction, the sliding frame drives the locking pin to engage with the connecting frame under the action of the spring. This makes the connection and disassembly of the heating tank and related components more convenient, thereby achieving the effect of quick disassembly and maintenance. It solves the problem of cumbersome disassembly and assembly, time-consuming and labor-intensive traditional connection methods, and improves the convenience and efficiency of equipment maintenance.
