The seal gasket is arranged between the window protection cover with the arm, and the inner end face of the window seat, and is fixed on the inner end face of the window seat, the rotary shaft is connected with the fixed seat through the bearing, and two ends of the bearing are respectively provided with the oil seals and are fixed through the clamping springs in located mode. The window protection cover device is simple in structure and convenient to use, completely avoids the situation that material operation on the inner side of a barrel can not be observed because coal is adhered to window glass and accumulated in the window seat, and resolves the problems that the window glass is difficult to clean and the window seat has dead angles.
Description
Technical field
The utility model relates to the form of the industries such as a kind of bin system for power plant's pulverized coal preparation system and other occasion, fluidized-bed combustion boiler, mine, metallurgy, cement, food, chemical industry; with the matching used windows be protected cover of Scraper window, especially a kind of with sealing can external operating window protective cover device.
Background technology
Scraper window generally is installed in and is difficult for often opening and having on the closed cylindrical shell of certain pressure, and it mainly plays component operating condition and indicating positions in the inspection section body of the outside.The cleaning of existing form generally is at the in-built shower nozzle of form, when fenestra is inboard long-pending when coal ash or foreign material are arranged, cleaned with compressed air or water by shower nozzle, but experimental results show that this single functional effect is undesirable, it is unclean often to leave the dead angle cleaning in form, be complete closed and certain pressure is arranged because of cylindrical shell in addition, in the very high hot gas of temperature is arranged, when coal sticks on the sight glass under the effect of coal dust at hot gas in flow process for a long time, only compressed air or the water by the permanent position is difficult to clean out, and then makes form because being stained with smudgy that coal ash becomes.
Summary of the invention
The utility model is will solve existing Scraper window cleaning totally and easily not glue coal ash and ambiguous technical problem, and provides a kind of in the built-in installation of cylindrical shell, the Window protective cover device of external operation.
For realizing above purpose, the technical solution of the utility model is achieved in that a kind of Window protective cover device, comprises form seat, band arm windows be protected cover, sealing mat, turning cylinder, holder, bearing, oil sealing, jump ring and handle; In the holder of form seat side turning cylinder is housed; turning cylinder is positioned on the end of hull outside turning handle is housed; band arm windows be protected cover is housed on the inboard end; and be provided with sealing mat between band arm windows be protected cover and the form seat inner face; sealing mat is fixed on the form seat inner face; be connected by bearing between turning cylinder and the holder, oil sealing is equipped with respectively at the bearing two ends, and fixing by the jump ring location.
Alignment pin is housed on the turning handle, and segmentation is equipped with the location blind hole on the corresponding hull outside face of turning handle movement locus, and turning handle cooperates with the split fix blind hole by alignment pin and is located by connecting, and realizes opening or closing of fixing windows be protected cover.
Form seat inner top side is equipped with windows be protected cover range spacer pin, is used for preventing that the windows be protected cover from damaging because rotating distance is excessive.
The windows be protected cover is for building the shape structure, and when windows be protected covers in the process of closing, the windows be protected cover is close to sealing mat.
The beneficial effects of the utility model are; Simple in structure, easy to use, stopped the sticking coal of sight glass and form seat inner product coal and do not observed the situation of the inboard material operation of cylindrical shell, solved that sight glass is difficult to clean and the form seat in leave the problem at dead angle.
Description of drawings
Fig. 1 is that structure of the present utility model is cutd open figure;
Fig. 2 is band arm windows be protected cover closure state schematic diagram;
Fig. 3 is band arm windows be protected cover opening schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, Window protective cover device of the present utility model, by housing 1, sight glass seat 2, form seat 3, band arm windows be protected cover 4, spacer pin 5, sealing mat 6, turning cylinder 7, holder 8, bearing 9, oil sealing 10, jump ring 12 and handle 11 form.
In the holder 8 of form seat 3 sides turning cylinder 7 is housed; turning cylinder 7 is positioned on the end in housing 1 outside turning handle 11 is housed; band arm windows be protected cover 4 is housed on the inboard end; and be provided with sealing mat 6 between band arm windows be protected cover 4 and form seat 3 inner faces; sealing mat 6 is fixed on form seat 3 inner faces; be connected by bearing 9 between turning cylinder 7 and the holder 8, oil sealing 10 is equipped with respectively at bearing 9 two ends, and fixing by jump ring 12 location.
Alignment pin 13(Fig. 3 is housed) on the turning handle 11; segmentation is equipped with the location blind hole on corresponding housing 1 lateral surface of turning handle 11 movement locus; turning handle 11 cooperates with the split fix blind hole by alignment pin 13 and is located by connecting, and realizes opening or closing of fixing windows be protected cover 4.
Form seat 3 inner top side are equipped with windows be protected cover 4 range spacer pins 5, are used for preventing that windows be protected cover 4 from damaging because rotating distance is excessive.
Windows be protected cover 4 is for building the shape structure, and in the process that windows be protected cover 4 is closing, windows be protected cover 4 is close to sealing mat 3.
Window protective cover device 4 is installed in form seat 3 sides; when needs are watched the inboard material operating condition of cylindrical shell; turning handle 11 makes band arm windows be protected cover 4 rotate to last locating hole place, left side by turning cylinder 7; this position just in time makes form open fully, and windows be protected cover 4 does not break away from sealing mat 6.(seeing Fig. 3 opening)
On the contrary; when check complete after turning handle 11; band arm windows be protected cover 4 is closed; in the process of closing because band arm windows be protected cover 4 can be received tighter and tighter for building the shape structure; when approximately forwarding vertical state to, handle 11 shows that windows be protected cover 4 closes fully; carry out spacing this moment with 13 pairs of handles of alignment pin 11, prevent handle 11 counter motions.The side-looking window seat 3 that puts in place in the pass is equipped with windows be protected cover 4 range spacer pins 5, to prevent that because of firmly excessive windows be protected cover 4 strokes surpass covering form stroke and lost efficacy.(seeing Fig. 2 closed condition)
In needs are observed cylindrical shell, during operating condition, windows be protected cover 4 is opened, not the time spent, windows be protected cover 4 is closed.Sealing mat 6 is housed on the form seat 3, for reaching sealing effectiveness, sealing mat 6 outstanding form seats 3, windows be protected cover 4 is for building the shape structure simultaneously, in the process that windows be protected cover 4 is closing, can be close to sealing mat 3 more receive tighter, to reach sealing effectiveness; Simultaneously when in the observation process; because windows be protected cover 4 is opened; having seldom, the coal dust of amount enters form seat 3; also can be when windows be protected cover 4 closes sight glass seat 2 be opened and clear up glass; because windows be protected cover 4 has good sealing function; so this operates the operation of not impact equipment, and easy to operate.
