Abstract
The utility model relates to a steel liner plastic container with a negative-pressure-resisting supporting device. The technical scheme is as follows: the steel liner plastic container with the negative-pressure-resisting supporting device comprises a container body, wherein the container body is internally provided with a containing cavity; the containing cavity of the container body is internally provided with an anticorrosive plastic liner and a resisting part, wherein the anticorrosive plastic liner is attached to the inner wall of the containing cavity, and the resisting part is used for resisting the anticorrosive plastic liner; the resisting part is of a compression spring arranged in the containing cavity of the container body; and the compression spring is axially arranged along the container body, and the external diameter of the compression spring presses the anticorrosive plastic liner arranged on the inner wall of the containing cavity of the container body. By adopting the technical scheme, the utility model provides the steel liner plastic container with the negative pressure-resisting supporting device, which can prevent the internal anticorrosive plastic liner from being shrunken and damaged due to negative pressure.
Description
Technical field
The utility model relates to a kind of steel-liner plastic container that has anti-negative pressure bracing or strutting arrangement.
Background technology
Plastics, rubber lining extensively apply to industry-by-industry as effective anticorrosive measure of container, equipment, pipeline.Because of negative pressure formed drum, take out flat, to come off etc. be the one of the main reasons that causes lining to destroy.Be head it off, the ring-type of band outer lining plastics or cage shape support usually can be set supporting backing layer in lining, reducing the influence of negative pressure, but this type of upholder will make to support and lose efficacy at work in case deform.Ring-type supports difficulty, cage shape support outer lining difficulty is installed in addition.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of and has prevented that inner anti-rot plastic lining is caused by negative pressure and takes out the steel-liner plastic container that has anti-negative pressure bracing or strutting arrangement flat and that damage.
For achieving the above object, the utility model provides following technical scheme: a kind of steel-liner plastic container that has anti-negative pressure bracing or strutting arrangement, include vessel, include cavity volume in the vessel, be provided with in the cavity volume of vessel and the anti-rot plastic lining of cavity volume inwall applying and the conflict part of conflict anti-rot plastic lining, described conflict part is the compression spring of being located in the vessel cavity volume, this compression spring axially is provided with along the vessel cavity volume, and the external diameter of compression spring presses with the anti-rot plastic lining that is attached on the cavity volume inwall of vessel.
Adopt technique scheme, the conflict part is a compression spring, and the external diameter of compression spring presses with the anti-rot plastic lining that is attached on the cavity volume inwall of vessel, be provided with like this is because compression spring can be conflicted by itself preset force and anti-rot plastic lining, and the strong point with a plurality of pitch of the laps formation of compression spring, each strong point is conflicted to the anti-rot plastic lining respectively, increased the conflict point, make the conflict power that the anti-rot plastic lining improves, in negative pressure, can not take out situation flat and that damage, and compression spring can also automatically reset after shunk by negative pressure, avoided the pressurized displacement.
The utility model further is set to: compression spring is coated with anti-rot plastic.
Wherein, anti-rot plastic and anti-rot plastic lining are polytetrafluoroethylene.
Adopt technique scheme, because the chemical industry solvent in the vessel or have corrosive liquid and know from experience, can prevent that then compression spring is corroded after outside compression spring, coating anti-rot plastic, thereby prolong the service life of compression spring the compression spring corrosion damage.Polytetrafluoroethylene has anti-corrosive properties preferably, and low price, and certainly, selecting other for use also is feasible as anti-rot plastics such as polyethylene or polypropylene.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
A kind of steel-liner plastic container that has anti-negative pressure bracing or strutting arrangement as shown in Figure 1, include vessel 1, include cavity volume 11 in the vessel 1, be provided with in the cavity volume 11 of vessel 1 and the anti-rot plastic lining 2 of cavity volume inwall 111 applyings and the conflict part of conflict anti-rot plastic lining 2.The conflict part is the compression spring of being located in vessel 1 cavity volume 11 3, and this compression spring 3 axially is provided with along vessel 1 cavity volume 11, and the external diameter of compression spring 3 and the anti-rot plastic lining 2 that is attached on the cavity volume inwall 111 of vessel 1 press.
Because the chemical industry solvent in the vessel 1 or have corrosive liquid for avoiding this class I liquid I with compression spring 3 corrosion, in the utility model embodiment, is coated with anti-rot plastic 32 at compression spring 3, and is set the service life that has prolonged compression spring 3 like this.
In the utility model embodiment, anti-rot plastic 32 and anti-rot plastic lining 2 are polytetrafluoroethylene, the utility model embodiment selects for use polytetrafluoroethylene to be because polytetrafluoroethylene has anti-corrosive properties preferably, and low price, certainly, selecting other for use also is feasible as anti-rot plastics such as polyethylene or polypropylene, is not giving unnecessary details here.
Claims (3)
