Abstract
The present invention provides a dust removal, an agglomerating machine and a cooler used in metallurgical industry, especially an anticlogging high sealing double-layer cindervalve, including an upper case, an upper valve plate, a center case, a lower valve plate, a lower case and a driving device of the upper and lower valve plates, an upper valve plate sealing frame set betweent the upper case and the middle case, the upper valve plate inserting in the upper valve plate sealing frame and contacting with the upper valve plate sealing frame, a lower valve plate sealing frame set between the center case and the lower case, the lower valve plate inserting in the lower valve plate sealing plate and contacting with the lower valve plate sealing plate. The sealing frames are square, a rubber sealing element is set in the contacting area of the sealing frame and the valve plate. One ends of the upper valve plate and the lower valve plate have dust draining hole, the other ends are connected with the driving device. The sealing frame is connected with the valve plate all the time in the course of still and movement of the valve plate, effectively reduces the opportunity of entering in the sealing frame of the material, effectively avoids material brush sealing plate.
Description
Technical field
The dusting apparatus that the present invention relates to use in the metallurgy industry, sintering machine, Coolers, especially a kind of blocking-proof high seal double layer dump valve.
Background technique
The dusting apparatus that in metallurgy industry, uses, sintering machine or Coolers, particulate dust in air blast or the exhausting system to be discharged, avoid outside wind to enter air blast or exhausting system inside again effectively, system takes to discharge intrasystem particulate dust with Double-deck cinder discharge valve more, during row's particulate dust, the upper strata seal valve is opened earlier, intrasystem particulate dust enters in the casing between the upper and lower two-layer valve, after the upper strata valve cuts out several seconds, lower floor's valve is opened, particulate dust in the casing between the two-layer valve is discharged, and then lower floor's valve cuts out.When making system unload particulate dust, the pressure of internal system is the influence of the row's of being subjected to particulate dust not.In the prior art, the form of Double-deck cinder discharge valve sealed valve has two kinds of cone valve and flap types, be not closed completely and the damage of the rubber seal of valve body is the disadvantage of prior art, cause sealing effect relatively poor, shorten working life, the repair and maintenance amount is bigger, the load increase that system leaks out and also causes system fan, and system energy consumption increases.The cone valve of prior art or flap type structurally all fail to address this problem, and the prior art rubber seal directly contacts with particulate dust, cause Sealing to be washed away or Sealing in buildup, make valve closing tight and cause and leak out.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, the blocking-proof high seal double layer dump valve of a kind of good sealing effect, long service life is provided.
The object of the present invention is achieved like this:
Blocking-proof high seal double layer dump valve of the present invention, the drive unit that comprises upper box, last valve plate, central box, lower valve plate, lower box and last lower valve plate, it is characterized in that being provided with the valve plate seal frame between described upper box and the central box, the described valve plate of going up inserts and also goes up the valve plate seal frame therewith in the valve plate seal frame this on and closely contact, between described central box and lower box, be provided with the lower valve plate seal frame, described lower valve plate insert in this lower valve plate seal frame and therewith the lower valve plate seal frame closely contact.
Described upward valve plate seal frame and lower valve plate seal frame are quadra, and its endoporus is concordant with the internal chamber wall of casing, and the surface of contact of seal frame and valve plate is the sealing surface that is provided with rubber seal.
A described end of going up valve plate and lower valve plate has ash-removing hole, and the other end is connected with drive unit.
The shape of the ash-removing hole of described upward valve plate and lower valve plate and the internal chamber wall of casing adapt.
The valve plate of blocking-proof high seal double layer dump valve of the present invention is in the process that opens and closes, valve plate contacts with the rubber seal of sealing all the time, do not enter and the chance that contacts rubber seal to particulate dust, be characterized in: open ash-removing hole on the valve plate, when ash-removing hole is relative with upper valve body, particulate dust is put into the casing between the upper and lower two-layer valve, when the promotion valve plate makes ash-removing hole leave the upper valve body end opening, valve closing, the sealing rubber pad of valve plate periphery contacts with valve plate all the time, has stopped particulate dust and has washed away sealing rubber part.
Compared with prior art, the invention has the advantages that valve plate is in the process that opens and closes, valve plate contacts with the rubber seal of sealing all the time.Rubber seal does not directly touch with particulate dust, and Sealing is not washed away by particulate dust, can buildup in the Sealing yet, and can not leak out in the valve place, and valve closing is tight.

Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
As depicted in figs. 1 and 2, a kind of blocking-proof high seal double layer dump valve of the present invention, comprise upper box 1, last valve plate 2, central box 4, lower valve plate 5, the drive unit 6 of lower box 7 and last lower valve plate, it is characterized in that between described upper box 1 and central box 4, being provided with valve plate seal frame 3, the described valve plate 2 of going up inserts this and goes up and also go up valve plate seal frame 3 therewith in the valve plate seal frame 3 and closely contact, between described central box 4 and lower box 7, be provided with lower valve plate seal frame 8, described lower valve plate insert 5 go in this lower valve plate seal frame 8 and therewith lower valve plate seal frame 8 closely contact.
Described upward valve plate seal frame 3 and lower valve plate seal frame 8 are quadra, and its endoporus is concordant with the internal chamber wall of casing, and the surface of contact of seal frame and valve plate is the sealing surface that is provided with rubber seal 9.
A described end of going up valve plate 2 and lower valve plate 5 has ash-removing hole, and the other end is connected with drive unit 6.
The shape of the ash-removing hole of described upward valve plate 2 and lower valve plate 5 and the internal chamber wall of casing adapt.
Working principle: as shown in Figure 2, when drive unit was pulled out valve plate 2, the ash-removing hole on the last valve plate 2 began to put ash when entering the end opening of top box 1, put behind the ash as shown in Figure 3, when drive unit is pushed to valve plate 2, when the ash-removing hole on the last valve plate 2 is released the end opening of top box 1 fully, put ash and finish.Lower valve plate 4 is identical with last valve plate 2 working principles, and two valve plates are alternately put ash up and down.In the process of and motion static at valve plate, seal frame contact with valve plate all the time, has reduced particulate dust effectively and has entered the interior chance of seal frame, has avoided the particulate dust to wash away sealing plate effectively.
