A kind of casing with heater
Technical field
The present invention relates to a kind of casing with heater, especially engineering is with the water tank of large-scale band heater.
Background technology
At present, known mode of heating to the water in the water tank is that heater is directly installed in the water tank, when heater maintenance or replacing, needs the water in the water tank is emitted; Not only form the waste of water; Maintenance time is also long, and the user was used less than hot water in the maintenance period, and the huge tanks influence is bigger.
Summary of the invention
In order to overcome the deficiency of prior art; The invention provides a kind of casing with heater; It can the spatial separation with heater come in when maintenance, made heater when maintenance, need not to discharge the water in the water tank, the waste of water when reducing the heater maintenance; Reduce maintenance time simultaneously, ensure user's water.
The technical solution adopted for the present invention to solve the technical problems is: a kind of casing with heater; Comprise casing and heater; It is characterized in that also comprising heating mantles and cover plate, said heating mantles is located in the casing, and said heater is located in the heating mantles; On heating mantles, be provided with casing in the opening that is communicated with, said cover plate cooperates with opening and can opening be opened or hermetically closing.
Opening part at said heating mantles is provided with rotating shaft, and said cover plate and rotating shaft are rotationally connected, and an end of said rotating shaft extends to outside the water tank, and the rocking arm of drive rotating shaft rotation is installed at the elongated end of rotating shaft.
In said heating mantles, be provided with rob support, on said rob support, being provided with can axially movable pull bar, and said pull bar one end is fixedly connected with a side of cover plate, and the other end of pull bar stretches out outside the casing.
Said heater is heat exchange coil or electric heater.
The dismountable grafting of said heating mantles and casing is fixed.
The present invention's beneficial effect compared with prior art is: the cover plate with an activity is closed the heating mantles opening at heater place; Form an insulating space, under the situation of not discharging water in the water tank, can heater be taken out; Maintenance or replacing; The waste of water reduces maintenance time simultaneously when reducing the heater maintenance, ensures user's water.

Among the figure: the 1st, casing, the 2nd, heater, the 3rd, heating mantles, the 4th, cover plate, the 5th, rotating shaft, the 6th, rocking arm, the 7th, pull bar, the 8th, rob support.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Embodiment one
Like Fig. 1, shown in 2, a kind of casing with heater comprises casing 1 and heater 2, and said heater 2 is heat exchange coil or electric heater.Characteristics of the present invention are also to comprise heating mantles 3 and cover plate 4; It is one that said heating mantles 3 is located at parallelly connected in the casing 1; Said heater 2 is located in the heating mantles 3, on heating mantles 3, be provided with casing 1 in the opening 31 that is communicated with, said cover plate 4 cooperates with opening 31 and can opening 31 be opened or hermetically closing.When maintenance, cover plate 4 forms separate space with opening 31 hermetically closings of heating mantles 3 in the heating mantles 3, and when heater 2 took out, the medium in the casing 1 can not run off; After maintenance was accomplished, cover plate 4 was opened opening 31, was communicated with casing 1 in the heating mantles 3, and heater 2 can heat the water in the casing 1.
In the present embodiment, be provided with rotating shaft 5 at opening 31 places of said heating mantles 3, said cover plate 4 is rotationally connected with rotating shaft 5, and an end of said rotating shaft 5 extends to outside the water tank 1, and the rocking arm 6 of drive rotating shaft 5 rotations is installed at the elongated end of rotating shaft 5.During operation, shaking wall 6 just can rotating shaft 5, and rotating shaft this moment 5 drives cover plates 4 rotations, with opening 31 hermetically closings of heating mantles 3 or open.
Embodiment two
As shown in Figure 3; Other the same with embodiment one, different is in said heating mantles 3, to be provided with rob support 8, on said rob support 8, being provided with can axially movable pull bar 7; Said pull bar 7 one ends are fixedly connected with a side of cover plate 4, and the other end of pull bar 7 stretches out outside the casing 1.Said heating mantles 3 is fixed with casing 1 dismountable grafting.When maintenance, pulling pull bar 7 outside casing 1, at this moment, pull bar 7 drives opening 31 hermetically closings of cover plate 4 with heating mantles 3, forms separate space in the heating mantles 3, and the medium when heater 2 takes out in the casing 1 can not run off.After maintenance was accomplished, toward interior pushing drawing rod 7, pull bar 7 drove cover plates 4 toward interior motion at this moment, and opening 31 is opened, and was communicated with in the heating mantles 3 with in the casing 1, and heater 2 can heat casing 1 interior water.
