Description
Technical Field
[0001] This utility model relates to the technical field of solar thermal storage boiler equipment, specifically to a solar thermal storage boiler. Background Technology
[0002] Solar energy, as an inexhaustible and clean energy source, has received widespread attention. Solar thermal storage boiler technology has emerged in this context, aiming to better utilize solar energy and achieve a sustainable energy supply.
[0003] In some related technologies, domestic hot water in some factories is heated by centralized solar energy to heat water storage boilers. However, the acquisition of solar energy depends on sunshine conditions. On cloudy days, rainy days, or in winter when the sunshine duration is short and the light intensity is weak, the solar thermal efficiency will be greatly reduced, and it may even fail to meet the normal operation requirements of the system, requiring the reliance on electric heating devices to continue to meet the usage needs.
[0004] However, most existing solar boiler electric heating devices heat the water inside the boiler by welding electric heating rods into the boiler. However, because the electric heating rods are submerged in water for a long time, scale will accumulate on their surface after prolonged use. This scale will affect the efficiency of subsequent heating and reduce the heating effect. When it is necessary to clean the electric heating rods, the fixed connection method makes it difficult to clean the surface of the electric heating rods. To solve the above problems, a solar thermal storage boiler is proposed. Utility Model Content
[0005] In view of this, the present invention provides a solar thermal storage boiler. The present invention separates the flange from the sealing sleeve by removing the bolts, and then removes the multi-tube heating rod installed on the sealing joint by holding the handle. After removal, it can be manually cleaned, which facilitates the cleaning of the surface of the heating rod.
[0006] To solve the above-mentioned technical problems, this utility model provides a solar thermal storage boiler, including a communicating vessel installed on one side wall of a water storage boiler, a solar heating pipe connected to one side of the communicating vessel, a support frame installed at the bottom of the water storage boiler, a fixing block installed on one side wall inside the water storage boiler, a heat insulation block installed on the side of the fixing block near the center of the water storage boiler, and multiple insertion ports installed in the middle of the heat insulation block. An opening is connected to the other side wall inside the water storage boiler, and a multi-tube heating rod is installed in the opening. A sealing sleeve is installed at one end of the multi-tube heating rod that passes through the side wall of the water storage boiler. A sealing joint is installed on the side of the sealing sleeve away from the opening. The inner ring size of the sealing sleeve is the same as the outer ring size of the sealing joint. A connecting plate is installed on the side of the sealing joint away from the opening, and a sealing component is installed on the side of the connecting plate away from the opening.
[0007] The number of heating elements on a multi-tube heating rod is the same as the number of sockets, and the size of the heating elements on the multi-tube heating rod is the same as the size of the sockets.
[0008] Multiple connecting blocks are arranged along the axial direction inside the multi-tube heating rod. Each connecting block is used for heat transfer between the heating rods on the multi-tube heating rod, so that the heat generated by each heating rod can cross, making the temperature of the entire heating area more stable and uniform, and also supporting each other to improve the stability of the multi-tube heating rod during operation.
[0009] The sealing sleeve is cylindrical and hollow. It is used to seal the gap between the multi-tube heating tube and the opening. The inner ring of the sealing sleeve has a sealing groove on the side away from the opening. The sealing groove is used to receive the sealing ring. Multiple first screw holes are provided on the surface of the sealing groove. The first screw holes are used to receive bolts.
[0010] The sealing assembly includes a sealing ring disposed on the side of the connecting plate near the opening. The sealing ring is used to reinforce and seal the connection between the opening and the sealing sleeve, thereby preventing water leakage at the connection. The sealing ring is adapted to the sealing groove. A flange is disposed on the side of the connecting plate away from the opening. The flange is used to fix the connecting plate and the sealing joint. The flange surface is provided with multiple second screw holes for installing bolts. The second screw holes correspond to the first screw holes and have the same size as the first screw holes. Each second screw hole contains a bolt for connecting and fixing the flange and the sealing sleeve.
[0011] The flange has a pair of access ports on the side away from the opening. These access ports are used to power the electronic components inside the sealing joint, thereby heating the multi-tube heating rod connected to the sealing joint.
[0012] A handle is provided on the side of the access port, which facilitates the insertion and removal of the flange, and thus the insertion and removal of the multi-tube heating rod. The handle is square-groove shaped.
[0013] A temperature sensor is connected to one side wall of the water storage boiler. The temperature sensor is used to detect changes in the water temperature inside the water storage boiler.
[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0015] 1. By removing the bolts, the flange can be separated from the sealing sleeve. Then, the multi-tube heating rod installed on the sealing joint can be removed by gripping the handle. After removal, it can be manually cleaned to facilitate the cleaning of the surface of the heating rod.
[0016] 2. The sealing ring is used to reinforce and seal the connection between the opening and the sealing sleeve, thereby preventing water leakage at the connection. The bolt is used to connect and fix the flange and the sealing sleeve. The bolt passes through the second threaded hole and is installed in the first threaded hole, thereby sealing the inner ring of the sealing sleeve by the sealing joint. The connecting plate, together with the flange, is connected to the sealing sleeve, thereby fixing the multi-tube heating rod installed on the sealing joint.
[0017] 3. The handle facilitates the insertion and removal of the flange, which in turn facilitates the insertion and removal of multi-tube heating rods. Attached Figure Description
