A kind of pressure-bearing type enamel inner container storage tank
Technical field
The utility model relates to a kind of storage tank, specifically a kind of pressure-bearing type enamel inner container storage tank.
Background technology
At present, there is the pressure-bearing weak effect in the employed storage tank of solar hot water system more, the unfavorable problem of heat insulation effect, and the heat-conducting medium in the storage tank contacts with making water, has influenced the cleaning of water quality.Along with the increase of service time, fouling occurs through regular meeting in the storage tank, and the inwall of storage tank is easy to also be corroded, in the service life that this greatly reduces storage tank, influenced people's normal life.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provides that a kind of long service life, pressure-bearing are effective, a kind of pressure-bearing type enamel inner container storage tank of safely cleaning.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with heat-insulation layer between shell and the enamel inner container, the inner chamber bottom of enamel inner container is provided with coil heat exchanger, two ports of coil heat exchanger are positioned at the side of storage tank, the port of its middle and upper part is the circulatory mediator inlet, the port of bottom is the circulatory mediator outlet, the below of storage tank cocycle media outlet is provided with cooling water inlet, and the top of shell is provided with hot water outlet, and the top of coil heat exchanger is provided with electric heating tube.
The inner bag of coil heat exchanger medium position is provided with down temperature tube, is provided with temperature tube between circulatory mediator outlet and the hot water outlet; The top of enamel inner container is provided with anodic magnesium rod, and the below enamel inner container of coil heat exchanger is provided with down anodic magnesium rod; The top of storage tank is provided with relief valve connection.
A kind of pressure-bearing type enamel inner container storage tank of the present utility model is compared with prior art, has characteristics such as reasonable in design, easy to use, long service life, pressure-bearing are effective, safely cleaning, operating efficiency height.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is a kind of structural representation of pressure-bearing type enamel inner container storage tank;
Accompanying drawing 2 is the vertical view of accompanying drawing 1.
Among the figure: 1, shell, 2, heat-insulation layer, 3, go up anodic magnesium rod, 4, electric heating tube, 5, coil heat exchanger, 6, anodic magnesium rod down, 7, hot water outlet, 8, go up temperature tube, 9, the circulatory mediator inlet, 10, temperature tube down, 11, circulatory mediator outlet, 12, cooling water inlet, 13, relief valve connection, 14, enamel inner container.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of pressure-bearing type enamel inner container storage tank of the present utility model, be provided with polyurethane high-pressure foam heat-insulation layer 2 between shell 1 and the enamel inner container 14, the inner chamber bottom of enamel inner container 14 is provided with coil heat exchanger 5,5 two ports of coil heat exchanger are positioned at the side of storage tank, the port of its middle and upper part is a circulatory mediator inlet 9, the port of bottom is circulatory mediator outlet 11, the below of storage tank cocycle media outlet 11 is provided with cooling water inlet 12, the top of shell 1 is provided with hot water outlet 7, and the top of coil heat exchanger 5 is provided with electric heating tube 4.
The enamel inner container 14 of coil heat exchanger 5 medium positions is provided with down temperature tube 10, is provided with temperature tube 8 between circulatory mediator outlet 9 and the hot water outlet 7; The top of enamel inner container 14 is provided with anodic magnesium rod 3, and the below enamel inner container 14 of coil heat exchanger 5 is provided with down anodic magnesium rod 6; The top of storage tank is provided with relief valve connection 13.
Polyurethane high-pressure foam heat-insulation layer 2 makes storage tank have high heat preservation performance.The enamel inner container 14 of storage tank has stronger pressure-bearing function and can effectively anticorrosion, antiscale, and coil heat exchanger 5 is isolated mutually with the use water in the enamel inner container 14, guarantees to make the water cleaning, and is harmless to human body.This storage tank is vertical, and significantly water temperature delamination is arranged, and can maximally utilise solar energy provides hot water fast.Dispose anodic magnesium rod in the storage tank, play protection storage tank enamel inner container, reduce the effect in service life of burn into prolongation storage tank.
A kind of its processing and fabricating of pressure-bearing type enamel inner container storage tank of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
