Abstract
Description
Technical Field
[0001] The utility model relates to the field of electric heater equipment, in particular to an inclined sun-shaped cloth tube three-part spiral baffle electric heater. Background Technique
[0002] The baffle of the heater is a structure installed inside the heater for guiding the flow direction of the fluid and adjusting the heat distribution. The baffle can also extend the residence time of the fluid in the heater, thereby increasing the contact time between the fluid and the heating tube, and achieving the effect of improving the heat transfer efficiency of the heater. When the existing three-part baffle is in use, there is a certain leakage flow in the triangular area, and the connection strength between the baffles is relatively low. During long-term use, the baffle may shift in position. After the integral spiral baffle appears corrosion, it needs to be replaced as a whole, resulting in a high cost. Content of the Utility Model
[0003] In order to overcome the deficiencies of the above existing problems, the utility model provides an inclined sun-shaped cloth tube three-part spiral baffle electric heater.
[0004] The technical solution adopted by the utility model to solve its technical problems is: an inclined sun-shaped cloth tube three-part spiral baffle electric heater, which includes a number of support rods evenly distributed around the same point. A number of staggered sector baffles are sleeved on the support rods. One side of the sector baffle is provided with a downward inclined flow guide plate, and the other side is provided with a support plate that fits the shape of the flow guide plate. During installation, the sector baffle is sleeved on the support rod, and two adjacent sector baffles are arranged staggeredly, so that the flow guide plate on one side of the upper sector baffle corresponds to the support plate on one side of the lower sector baffle, and is further locked by bolts to complete the installation.
[0004]
[0005] Preferably, a number of flow guide grooves located on the same arc are opened on the sector baffle and the flow guide plate to improve the mixing efficiency of the fluid to be heated during the heating operation.
[0006] Preferably, a number of heating tube holes are opened on the sector baffle, and a number of heating tubes distributed in an inclined sun shape are fixedly connected in the heating tube holes. This heating tube distribution method can effectively improve the heat exchange efficiency.
[0005]
[0007] Preferably, one side of the top surface of the support plate is provided with a platform that fits the sector baffle, and holes for the support rod to pass through are opened at corresponding positions on one side edge of the sector baffle and the platform. During installation, only three support rods are needed to complete the fixation of the sector baffle, which is convenient for installation and can save processing costs.
[0008] The beneficial effect of the present invention is that, during installation, only three support rods are needed to limit the upper and lower fan-shaped baffles through the holes at the corresponding positions of the platform and the fan-shaped baffles, and then they are fixed by bolts. During use, if the baffle is damaged, it can be replaced individually, which reduces costs and is easy to install. The stacking installation method of the platform and the fan-shaped baffles can enhance the fixing strength between the baffles. During use, the guide plate can reduce the possibility of leakage between the fan-shaped baffles. In addition, during heating, the guide groove can improve the mixing efficiency of the fluid to be heated. BRIEF DESCRIPTION OF THE DRAWINGS

[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 1-3 The shown type of oblique Japanese-shaped tube three-part spiral baffle electric heater includes a number of support rods 1, which are evenly distributed with the same point as the axis. A number of staggered fan-shaped baffles 2 are sleeved on the support rods 1, and a guide plate 3 obliquely pointing downward is provided on one side of the fan-shaped baffle 2, and a support plate 4 that matches the shape of the guide plate 3 is provided on the other side. During installation, the fan-shaped baffle 2 is sleeved onto the support rod 1, and the two adjacent fan-shaped baffles 2 are staggered so that the guide plate 3 on one side of the upper fan-shaped baffle 2 corresponds to the support plate 4 on one side of the lower fan-shaped baffle 2, and is further tightened by bolts to complete the installation.
[0017] The sector baffle plate 2 and the flow guide plate 3 are provided with a number of flow guide grooves 6 located on the same arc, which can improve the mixing efficiency of the fluid to be heated during the heating operation.
[0018] The sector baffle plate 2 is provided with a number of heating tube holes 7, and a number of heating tubes 8 distributed in an inclined "day" shape are fixedly connected in the heating tube holes 7. This distribution method of the heating tubes can effectively improve the heat exchange efficiency.
[0019] On one side of the top surface of the support plate 4, there is a platform 5 that fits the sector baffle plate 2. Holes for the support rods 1 to pass through are provided at corresponding positions on one side edge of the sector baffle plate 2 and the platform 5. During installation, only three support rods are needed to complete the fixation of the sector baffle plate, which is convenient for installation and can save processing costs.
[0020] Specific embodiment: The sector baffle plate 2 is sleeved on the support rod 1, and two adjacent sector baffle plates 2 are arranged staggeredly, so that the flow guide plate 3 on one side of the upper sector baffle plate 2 corresponds to the support plate 4 on one side of the lower sector baffle plate 2. At this time, the buckle 6 is engaged with the card slot 5, and the sector baffle plate 2 is further locked by bolts to complete the installation.
[0021] This design is ingenious. During installation, the upper and lower sector baffle plates can be limited by only three support rods through the holes at the corresponding positions of the platform and the sector baffle plate, which is convenient for installation. And when the baffle plate is damaged, it can be replaced separately to reduce costs. When in use, the flow guide plate can reduce the possibility of leakage between the sector baffle plates. In addition, during the heating operation, the flow guide grooves can improve the mixing efficiency of the fluid to be heated.
[0022] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
