DETAILED DESCRIPTION

[0014] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0015] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0016] like Figure 1-4An efficient heating three - part spiral baffle electric heater shown in the figure includes a fixed plate 1. Above the fixed plate 1, a housing 3 is fixedly connected by bolts. On one side below the housing 3, a water inlet 4 is fixedly connected. On one side above the housing 3, a water outlet 5 is fixedly connected. A rotating device is arranged inside the housing 3. The rotating device includes a connecting member 7 driven by a motor 6. The connecting member 7 is arranged inside the fixed plate 1. Above the connecting member 7, a number of heating tubes 8 are fixedly connected. On the outer side of the heating tubes 8 and on the top surface of the connecting member 7, a threaded column 9 is fixedly connected. A inner housing 10 is sleeved on the outer side of the heating tubes 8. Inside the bottom of the inner housing 10, a thread is opened which is used in cooperation with the threaded column 9. Outside the bottom of the inner housing 10, a lower rotating plate 11 fixedly connected to the inner housing 10 is sleeved. Below the top inside the housing 1, an upper rotating plate 12 is arranged. Between the lower rotating plate 11 and the upper rotating plate 12, a number of support rods 13 are fixedly connected by bolts. A baffle 14 is sleeved on the support rods 13.

[0017] The baffle 14 is composed of a number of baffle plates 15. Inside the baffle plates 15, an arc - shaped connecting member 16 is arranged. Inside the arc - shaped connecting member 16, a groove 17 is opened. On the outer side of the inner housing 10, a clamping block 18 which fits the groove 17 is fixedly connected. On one side of the baffle plate 15, a first connecting plate 19 is arranged. On the other side, a second connecting plate 2 which is used in cooperation with the first connecting plate 19 is arranged. Bolt holes 20 are opened at corresponding positions of the first connecting plate 19 and the second connecting plate 2. During installation, first, the baffle plates 15 are sequentially clamped on the outer side of the inner housing 3. At this time, the first connecting plate and the second connecting plate are in contact with each other and are reinforced by bolts. Then, the support rods 13 are passed through the baffle plates 15 until they are located on the lower turntable 11. Finally, the upper turntable 12 is placed on the top of the support rods 13 and is fixed by bolts.

[0018] There are three heating tubes 8, which are distributed in an inclined "day" character shape. Specific embodiments

[0019] During installation, first, the baffle plates 15 are sequentially clamped on the outer side of the inner housing 3. Then, the support rods 13 are passed through the baffle plates 15 until they are located on the lower turntable 11. Then, the upper turntable 12 is placed on the top of the support rods 13 and is fixed by bolts. Finally, the inner housing 10 is screwed onto the threaded column 9, the housing 1 is covered, and is locked by bolts. When in use, the motor 6 drives the connecting member 7 to带动 the inner housing 10 and the baffle 14 to rotate along the flowing direction of the liquid to be heated, effectively improving the heating efficiency.

[0020] This design is ingenious. By driving the connecting member with a motor to带动 the inner housing and the baffle to rotate along the flowing direction of the liquid to be heated, the heating efficiency can be effectively improved. And the baffle is composed of a number of baffle plates combined and spliced, which is convenient for installation. If a baffle plate is damaged, only the damaged baffle plate needs to be replaced separately.

[0021] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
