Description
Technical field
The utility model relates to electric control box, is a kind of dust explosion protection electric appliance control box that is used under the explosion-proof environment specifically.
Background technology
The dust explosion protection control cabinet mainly uses in the environment of explosive dust is arranged, as production places such as timber, grain depot, feed, plastics, papermaking.In the air in these places, filling the air a large amount of inflammable and explosive dust usually, therefore need use dust explosion protection control cabinet with good dustproof and anti-explosion performance.Present employed dust explosion protection control cabinet generally all adopts aluminium alloy compression casting shaping housing, or by external import.This just makes the price of dust explosion protection control cabinet generally higher, and processing technology is also complicated, and the processing dimension of housing also is subjected to certain restriction.
Summary of the invention
It is comparatively simple that the purpose of this utility model is to design a kind of manufacture craft, and price is comparatively cheap, and performance index can reach the dust explosion protection control cabinet of instructions for use.
According to scheme provided by the utility model, on the right side of casing unlimited opening is arranged, connect the door-plate that is used for seal case at this opening, it is characterized in that: the rubber gasket that annular is set between the contact-making surface of casing and door-plate.
Madial wall near its opening on casing is provided with framework, and the outside of this framework is connected with the madial wall of casing, and door-plate is pointed in the inboard of framework, and connects rubber gasket in this inboard end.On framework, be provided for connecting the door-plate erection column of door-plate, in the door-plate erection column, counterbore be set, internal thread is arranged at the inwall of counterbore.
The lateral left vertical bending of framework, form left bending section, the vertical to the right bending in the inboard of framework, form right bending section, the vertical to the left earlier bending in the edge of door-plate forms horizontal bending section, vertical to the inside again bending, form vertical bending section, the horizontal bending section length of door-plate is slightly less than the curved segment length of right folding of framework.Setting element erection column on the casing left side wall has screwed hole in the element erection column.U type groove is arranged on the cross section of rubber weather strip, in rubber weather strip, form air bag.
The utility model has the advantages that: manufacture craft is comparatively simple, and price is comparatively cheap, because it adopts Welding Structure, the size of housing processing also is not limited in several fixing sizes, can be according to actual instructions for use processing and fabricating.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Embodiment
As shown in Figure 1: the dust explosion protection control cabinet is mainly by casing 1, erection column 2, door-plate 3, door-plate erection column 4, rubber weather strip 5, fixed installation hole 6.
On the right side of casing 1 unlimited opening is arranged, connect the door-plate 3 that is used for seal case 1, the rubber gasket 5 of annular is set between the contact-making surface of casing 1 and door-plate 3 at this opening.Madial wall near its opening on casing 1 is provided with framework, and the outside of this framework is connected with the madial wall of casing 1, and door-plate 3 is pointed in the inboard of framework, and connects rubber gasket 5 in this inboard end.On framework, be provided for connecting the door-plate erection column 4 of door-plate 3, in door-plate erection column 4, counterbore be set, internal thread is arranged at the inwall of counterbore.The lateral left vertical bending of framework, form left bending section, the vertical to the right bending in the inboard of framework, form right bending section, the vertical to the left earlier bending in the edge of door-plate 3 forms horizontal bending section, vertical to the inside again bending, form vertical bending section, the horizontal bending section length of door-plate 3 is slightly less than the curved segment length of right folding of framework.Setting element erection column 2 on casing 1 left side wall has screwed hole in element erection column 2.U type groove is arranged on the cross section of rubber weather strip 5, in rubber weather strip 5, form air bag.
Wherein casing 1 adopts the welding forming mode, and the technology of argon protection precision welding is all adopted in each bar splicing slit, guarantees that casing deflection after integral solder can control to minimum.Erection column 2 adopts female thread structure, and welding and casing inner bottom part are used for fixing electric original paper mounting panel.All roll over the curved structure of twice around door-plate 3 adopts, make door panel structure firm, the distortionless metaboly in welding back.Door-plate erection column 4 is internal thread and is the structure of blind hole, even when guaranteeing to have in the screw thread material such as dust water, and can be toward the casing internal leakage yet.Rubber weather strip 5 adopts the structure of U type gasbag-type thickening type, and uses thermal endurance, and air-tightness, combination properties such as resistance to water be elastomeric material making preferably all.Make the sealing property of whole box body can be good at guaranteeing.Fixed installation hole 6 is used for fixing installs the dust explosion protection control cabinet.
The dust explosion protection control cabinet adopts high quality carbon steel plate or stainless steel materials, after several roads preceding working procedures such as shearing pressing and bending, with the technology welding forming of the accurate welding of argon protection.Adopt thermal endurance between dust explosion protection control cabinet casing and the door-plate, air-tightness, combination properties such as resistance to water be rubber weather strip sealing preferably all, and the rubber weather strip structure is also through optimizing, be made into the structure of U type gasbag-type thickening type, make the sealing property between casing and the door-plate reach instructions for use.
