Detailed description of the invention
In order to further illustrate technical scheme of the present invention, in conjunction with Figure of description, the specific embodiment of the present invention is as follows:
As shown in Figure 1, the invention discloses a kind of safety anti-blocking from cooling observation device, comprise the ring flange 1 of band peep hole 2, flange steel tube 6, ball valve 8 and observation body steel pipe 13, described flange steel tube 6 is heat-resistance stainless steel steel pipe, be fixedly connected between ring flange 1 and ball valve 8, observation body steel pipe 13 one end is fixedly connected with ball valve 8, the other end is welded on industrial furnace burner hearth to be observed, the inner relevant position of burner hearth reserves the hole identical with this observation body steel pipe 13 cross section, is convenient to Real Time Observation inner operating.
The peep hole 2 of described ring flange 1 is the visor of the high temperature resistant quartz glass through special processing, transparency is good, resistance to 1000 DEG C of high quartz glass fixing devices are made up of flange, pad, bolt, nut peace packing ring, and pad seals between ring flange and flange steel tube.
As shown in Fig. 2 a, 2b, this observation device also comprises rubber brush 3, rubber brush rotating shaft (not shown) has been crossed in the middle of ring flange 1 peep hole 2, and controlled by visor external knob (not shown), rubber brush 3 width and flange steel tube 6 equal diameters, axial sides is close to peep hole 2 visor, be fixed on rotating shaft fixture by the nut of axle head, rotate through the knob (not shown) of the rotating shaft outside of visor, rubber brush 3 around the shaft 360 DEG C, center freely rotates, in order to clear up flange steel tube 6 surrounding dust.As shown in Figure 2 b, on flange steel tube 6, be positioned at flange steel tube 6 bottom, lean on the ash-removing hole 4 being provided with steel tubular into peep hole 2 side, diameter is about 2-3cm, and as shown in Fig. 5 a, Fig. 5 b, ash-removing hole 4 is also furnished with and puts grey bolt 5 as plug.When observing, bolt 5 is twisted off and put ash, when normal operation, bolt 5 is screwed on and prevents from leaking out.
As shown in Figure 3, correspondingly-sized flange steel tube 6 there is cooling duct 7, between peep hole 2 and ball valve 8.When ash-removing hole 4 puts ash, the cooling air of the inside can spray from ash-removing hole 4 to be taken out of ash and to cool observation device.Cooling duct 7 by stainless steel tube and on the spot valve form, integral solder is on flange steel tube 6, and diameter is about 10 ~ 15cm.By compressed air, cooling air pressure is greater than and is observed equipment more than pressure 1.2kPa.
When observing through the peep hole 2 on ring flange 1, by rotation rubber brush 3 spin axis terminal, cleaning flange steel tube 6 surrounding dust, when amount of dust is larger, the plug nut 5 opened on ash-removing hole 4 carries out ash discharge.Open the control valve of cooling-air pipe 7, carry out cooling and blowback ash.
