Abstract
The utility model relates to a crushing device for fuel coal, which mainly comprises a barrel body 1, a lining board 2, and a rotary body assembly. The utility model is characterized in that the inner cavity of the barrel body 1 is composed of at least two cylinders with different diameters; a hammer head 5 in the rotary body assembly is hinged with a hammer frame 8 through a chain ring 3, the hammer frame 8 is fixedly connected with a vertical shaft 10 and rotates following the vertical shaft 10. The utility model has the advantages of large crushing rate, small discharged grains, and convenient processing, installation and maintenance, and the service lives of the key components of the crushing device for fuel coal are extended.
Description
The utility model belongs to the improvement of broken disintegrating apparatus, says it is a kind of breaker of bunker coal definitely.
Utilize the broken bunker coal of coal pulverizer to belong to known technology and be widely used in fields such as building materials, metallurgy.Yet existing coal pulverizer remains in the little deficiency of comminution ratio, and the coal of pulverizing after processing often will carry out second-time breakage again after screening.
The purpose of this utility model is: increase comminution ratio, improve quality, the raising work efficiency of discharging by the improvement to the coal pulverizer structure.
Vertical coal pulverizer provided by the utility model comprises cylindrical shell, liner plate and rotating body component, it is characterized in that: the inner chamber of cylindrical shell is made up of the cylinder that at least two sections diameters do not wait.The inner chamber of cylindrical shell is made of the cylinder that three sections diameters increase successively from top to bottom.
Rotating body component of the present utility model is made up of the tup that chain link is connected on the hammer carrier jointly by vertical shaft, through the solid one group of hammer carrier on vertical shaft of binding.Wherein can to select outline be 120 ° triangle convex at interval to hammer carrier, and the pin-and-hole that is positioned at high spot cooperates the end with chain link to be hinged on the hammer carrier with bolt.
For the coal that prevents larger particles directly falls into lower floor, make the high spot that the faces two hammer carriers mutually 60 ° of installations of staggering in the utility model.
Be in same consideration, the utility model is on the inwall of liner plate, and respectively there is a circular boss both sides up and down that are positioned at each tup.Consider that the accumulation of coal dust may appear in the boss top, for anti-phenomenon here takes place, circular boss is welded on the liner plate inwall after can selecting for use round steel to bend.
For the ease of processing and installation, each hammer carrier is made up of a pair of hammer plate in the utility model, and each is to having a lining 12 between the hammer plate, and every plate faces a lining 13 between two hammer carriers.
Introduce embodiment of the present utility model in detail below in conjunction with Figure of description.
Figure of description 1 is a structural representation of the present utility model;
Figure of description 2 is that the A of accompanying drawing 1 is to view;
Figure of description 3 is that the B of accompanying drawing 1 is to view.
In above-mentioned accompanying drawing, 1-cylindrical shell, 2-liner plate, 3-chain link, 4-boss, 5-tup, 6-upper cover plate, 7-coal feed point, 8-hammer carrier, 9-belt pulley, 10-vertical shaft, 11-bearing, 12-lining, 13-lining, 14-lower cover, 15-coal outlet, 16-bearing.
As shown in the figure, cylindrical shell 1 of the present utility model is formed by A3 rolled steel plate system.The inner chamber of cylindrical shell 1 is formed (can select as required more than two sections or three sections) by three sections cylinders that diameter from top to bottom increases successively.The characteristics of this structure are to form several sections fracture area, and make the coal that will fall after the epimere fragmentation enter the broken center of hypomere, and this structure helps improving comminution ratio.The profile of cylindrical shell 1 both can be selected structure shown in the accompanying drawing 1, also can select and the corresponding step structure of cavity shape, and the latter was than the former economical with materials.The upper end of cylindrical shell 1 is fixedly connected with a upper cover plate that has coal feed point 76 of being made by grey cast-iron, and the lower end of cylindrical shell 1 is fixedly connected with the lower cover of being made by grey cast-iron that has coal outlet 15 14.Whole table apparatus can be put and connect firmly and having on the pedestal of coal bunker by seat.On cylindrical shell 1, can access door be installed so that installation and maintenance.
Bearing 11 that vertical shaft 10 is provided with on upper cover plate 6 and lower cover 14 with one heart and 16 effects are positioned the axis place of cylindrical shell 1.Axially have keyway on the vertical shaft 1, one group of hammer carrier 8 is solid on vertical shaft 10 through binding.Each hammer carrier 8 is by a pair of hammer plate and be positioned at the lining 12 of hammer between plate and form.The hammer plate is made by the A3 steel, and its outline is made the triangle of 120 ° of spaces, cooperates the end with chain link 3 to be hinged between a pair of hammer plate of hammer carrier 8 with bolt at the pin-and-hole of each angle high spot.One lining, 13 location are arranged between the adjacent hammer carrier.The joint number of chain link 3 is by the intracavity diameter decision of cylindrical shell 1.The articulated tup 5 of the other end of chain link 3.In the work, tup 5 is in a kind of quick condition, thereby has both helped strengthening crushing effect, the service life that helps improving equipment again.Corresponding with tup 5, the inner chamber of cylindrical shell 1 is provided with liner plate 2, and it act as the service life that prolongs cylindrical shell.
In order further to improve the ratio of reduction of coal, the utility model has taked two attachedly to help measure, one, every high spot that faces hammer carrier 8 mutually 60 degree that stagger is in twos installed; Two, on liner plate 2, the upper and lower sides that is positioned at each hammer carrier 8 all is provided with an annular boss 4 of being made by round steel.Foregoing description can impel the coal of whereabouts to enter the zone of action of tup and chain link effectively.
In the work, rotating body component drives through belt pulley 9 and runs up, and the bunker coal that enters cylindrical shell 1 inner chamber by coal feed point 7 is pulverized under the bump of chain link 3, tup 5 and liner plate 2, and entered coal store through coal outlet 15 at hammer carrier 8.
The utility model has the advantages that: comminution ratio is big, and discharging-material size is little, has improved the pass Key parts service life, processing, installation, maintenance are convenient.
