Abstract
The utility model discloses a shock prevention and abrasion resistance electric heater. The shock prevention and abrasion resistance electric heater comprises a container flange tube plate, a heating tube bundle and guide plates, wherein the heating tube bundle is paved through the container flange tube plate, and the guide plates are arranged in the flow direction of a medium at intervals. The guide plates are provided with through holes corresponding to heating tubes of the heating tube bundle. The inner walls of the through holes are fixedly connected with the outer walls of seamless steel tubes. The heating tubes penetrate through the seamless steel tubes to be contained, and the internal diameter of each seamless steel tube is matched with the external diameter of the corresponding heating tube. Therefore, the contact area of the heating tubes and the seamless steel tubes is enlarged, accordingly, electric heating tubes installed inside a container cannot be shocked and mutually abraded when the medium is heated and flows, and the service life of the electric heating tubes can be prolonged.
Description
Technical field
The utility model relates to the wear-resistant electric heater of a kind of protecting against shock, belongs to the manufacture field of electric heater.
Background technology
The deflector of installing in existing electric heater is sheet metal (thickness is 3-5mm), heating (electric heating tube) is from passing the water conservancy diversion plate hole, impact during media flow can cause the electric heating tube vibration, electric heating tube and the mutual friction of deflector phase during vibration, due to electric heating tube outer wall very thin (thickness is 1-1.2mm), long-term friction can be worn out by electric heating tube, causes electric heater to damage.Directly impact is produced, and causes unnecessary loss.
The utility model content
The utility model is for the deficiencies in the prior art, provide a kind of protecting against shock wear-resistant electric heater, it is by providing a kind of deflector of new structure, to avoid heat medium impact to heating tube when flowing to cause the mutual wearing and tearing between deflector and heating tube, reach the purpose that increases the service life.
For realizing above technical purpose, the utility model will be taked following technical scheme:
The wear-resistant electric heater of a kind of protecting against shock, the heating tube bundle of comprise the vessel flange tube sheet, laying by the vessel flange tube sheet and along the spaced deflector of media flow direction; Deflector is offered through hole corresponding to each heating tube of heating tube bundle, and the inwall of described through hole is fixedly connected with the outer wall of seamless steel pipe, and described heating tube passes seamless steel pipe and puts, and the external diameter of the internal diameter of seamless steel pipe and heating tube is suitable.
The inwall of described through hole and the outer wall of seamless steel pipe are fixed by welding manner.
Tight fit connection between described seamless steel pipe and heating tube.
According to above technical scheme, with respect to prior art, the utlity model has following advantage:
The utility model is fixedly connected with the inwall of deflector through hole with the outer wall of seamless steel pipe, described heating tube passes seamless steel pipe and puts, and the internal diameter of seamless steel pipe and the external diameter of heating tube are suitable, therefore, contact-making surface between heating tube and seamless steel pipe is large, so being arranged in container, electric heating tube can, because long-term heat medium weares and teares mutually to the impact of heating tube when mobile, not reach the purpose that increases the service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of deflector installation position in Fig. 1;
Wherein: vessel flange tube sheet 1; Deflector 2; Heating tube bundle 3; Seamless steel pipe 4.
The specific embodiment
Below with reference to accompanying drawing, explain the technical solution of the utility model.
As shown in Figure 1, the wear-resistant electric heater of protecting against shock described in the utility model, the heating tube bundle that comprises the vessel flange tube sheet, lays by the vessel flange tube sheet and along the spaced deflector of media flow direction, spacing between deflector is 200-300mm, deflector is offered through hole corresponding to each heating tube of heating tube bundle, the inwall of described through hole and the outer wall of seamless steel pipe are fixed by welding manner, and the length of this seamless steel pipe is 20-30mm; The internal diameter of described seamless steel pipe and the external diameter of heating tube are suitable, and tight fit connection between seamless steel pipe and heating tube.Hence one can see that: because the contact-making surface between heating tube and seamless steel pipe is large, therefore, electric heating tube is arranged in container can, because long-term heat medium weares and teares mutually to the impact of heating tube when mobile, not reach the purpose that increases the service life.
