Description
Technical field
The utility model relates to noble metal and reclaims field, relates in particular to rotary kiln charging cover.
Background technology
Rotary kiln refers to rotary calcining kiln (being commonly called as rotary kiln), belongs to building equipment class. Rotary kiln can be divided into cement kiln, chemical metallurgy kiln and limekiln by material handling difference. Cement kiln is mainly used in calcination of cement clinker, point dry production cement kiln and the large class of wet production cement kiln two. Chemical metallurgy kiln is mainly used in the poor iron ore magnetic roasting of metallurgy industry steel plant; Chromium, josephinite oxidizing roasting; Refractory factory roasting high-aluminium vanadine ore deposit and aluminium manufacturer's roasting grog, aluminium hydroxide; The class mineral such as chemical plant roasting chrome ore and chromite ore fine. Active lime and light dolomite that limekiln (being active lime kiln) is used for roasting steel plant, ferroalloy works.
It is serious that existing chemical metallurgy kiln charging aperture leaks cigarette gas leak phenomenon, and structural instability, and long-term use is easily out of shape, and heat insulation effect is poor having much room for improvement also.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of stabilized structure, good seal performance, and can well follow combustor, feed screw to connect, the rotary kiln charging cover of good heat insulating.
For realizing the utility model object, provide following technical scheme: rotary kiln charging cover, it is characterized in that comprising cover body, described cover body is made up of the cover body of the two sections of connections in front and back, front cover body lower semisection is set to taper bucket, taper bucket end is provided with ash hole, in ash hole, be provided with fire brick layer, front cover body upper semisection is set to semicircle, front shroud surface is provided with screw machine interface, thermometer hole, combustor interface, flame-observing hole, fire verify, described front faceshield side wall is provided with wind-supplying mouth, in described rear cover body, be provided with the horizontal and vertical reinforcement fixed mount being crisscross arranged of angle steel, in the cover of front and back, be provided with the fire clay that thickness is 150mm.
As preferably, described rear cover body upper semisection is semicircle, and lower semisection be square, and rear cover body rear end face is provided with the flange connector of inclination, and described flange connector and rotary kiln charging aperture are bolted to connection.
As preferably, described horizontal angle steel and sole bar angle are positioned at same plane and intersect vertically.
The utility model beneficial effect: the utility model effectively overcomes prior art poor sealing performance, holds yielding problem, has greatly extended the service life of rotary kiln.
