Detailed Description
The following detailed description of the present utility model is provided with reference to the examples and the accompanying drawings, so that those skilled in the art can more clearly understand the technical scheme of the present utility model, but the scope of the present utility model is not limited thereto.
As shown in fig. 1 to 5, an electric heating device seal cover and a cooling tower adopting the device comprise a spray water tank 1, wherein an electric heating device 2 is arranged on a side plate of the spray water tank 1, a heating part 21 of the electric heating device 2 is arranged in the spray water tank 1, in the embodiment, as shown in fig. 1, the heating part 21 is an electric heating pipe, a fixing seat 3 is arranged on the side plate of the spray water tank 1, the fixing seat 3 and the side plate of the spray water tank 1 are of an integrated structure, the heating part 21 of the electric heating device 2 penetrates through the fixing seat 3 to extend into the spray water tank 1, and the fixing seat 3 is connected with an opening end of the seal cover 4 and is in sealing detachable connection.
Preferably, as shown in fig. 2 and 3, the open end of the sealing cap 4 comprises a sealing plane 41, and an outer protrusion 42 is provided on the outer edge of the sealing plane 41; as shown in fig. 4 and 5, the connection part between the fixing base 3 and the opening end of the sealing cover 4 is provided with an inner protrusion 31 and a fixing plane 32. The inner protrusions 31 and the outer protrusions 42 have the same number, when the sealing cap 4 is connected with the fixing base 3, the outer protrusions 42 of the sealing cap 4 pass through the gap between the two inner protrusions 31 on the fixing base 3, so that the sealing plane 41 of the sealing cap 4 contacts with the fixing plane 32 on the fixing base 3, then the sealing cap 4 is rotated, the sealing cap 4 rotates relative to the fixing base 3, and the outer protrusions 42 of the sealing cap 4 enter the gap between the fixing plane 32 on the fixing base 3 and the inner protrusions 31, so that the sealing cap 4 is fixedly connected on the fixing base 3.
Preferably, as shown in fig. 2 and 3, the outer protrusion 42 is provided with a connection surface 43 having a spiral slope. In this way, when the seal cover 4 is rotated, the connection surface 43 is a spiral inclined surface, so that the contact between the sealing plane 41 of the seal cover 4 and the fixing plane 32 on the fixing seat 3 is more compact; in order to further increase the sealing effect, a sealing layer is disposed on the sealing plane 41, and the sealing layer may be coated on the sealing plane 41, or may be a sealing gasket or the like.
