Abstract
The utility model discloses a single-stage hammer crusher comprising a housing, wherein, a feed opening is arranged at the upper part of the housing; a hammer plate is rotatably assembled at the lower part of the interior of the housing through a rotor; an upper impact plate is arranged at the top part of the inner wall of the housing and positioned above the hammer plate; a rear impact grid plate with a grate seam is arranged at the rear upper part of the inner wall of the housing opposite to the feed opening; a space reserved among the hammer plate, the upper impact plate and the rear impact grid plate forms an impact crushing cavity; the upper end of the rear impact grid plate is connected with the upper impact plate; and a grid plate connected with the rear impact grid plate is positioned inside the housing and arranged at the periphery of the hammer plate in a surrounding manner. Due to the fact that the wear loads of the hammer head, a lining board, the impact plate and the grid plate which are provided by the utility model are only 20-30% as large as those of a conventional crusher and that a great amount of harmful work previously contributing to abrasion-related damages to the hammer head, the impact plate, the grid plate and the lining board is converted to useful work which can be used for crushing materials, the single-stage hammer crusher achieves larger crushing efficiency than the conventional crusher and has an obviously greater output of electrical load per unit when compared with similar products.
Description
Technical field
The utility model relates to crushing mechanism, especially a kind of single block hammer crusher.
Background technology
At present in the medium-hard fine crusher of domestic existing fragmentation, as hammer mill and impact breaker and single block hammer crusher etc., these equipment part that in use all comes with some shortcomings to some extent.The tablet that goes out of traditional hammer mill is provided with sieve plate, and discharging-material size is easy to control, but feed size is about 30-280mm, and below the discharging-material size 15mm, so its ratio of reduction is less, and product faller gill shape content is bigger.And traditional impact breaker is the distortion of hammer mill in fact, just changes movable tup into fixed hammer, has adorned 1-2 counterpunch board over against the tangential direction of rotor tup on casing, and has removed original sieve plate.Though its product particle is cubic,,, can only be used for coarse crushing and broken so its discharging particle diameter is bigger because of there not being sieve plate.
The utility model content
The purpose of this utility model is to provide that a kind of ratio of reduction is big, discharging-material size is little and uniform single block hammer crusher.
The technical scheme of crusher hammer dish of the present utility model is: a kind of single block hammer crusher, comprise casing, casing top is provided with charging aperture, the bottom is equipped with the hammer dish by rotor rotation in the casing, the inwall top of described casing is provided with counterpunch board in hammer dish top, the inwall upper back of relative charging aperture is provided with the back counterattack grate plate that has the seam of combing in the casing, leave the space between hammer dish and last counterpunch board, the back counterattack grate plate and form counterattack crushing chamber, the upper end of back counterattack grate plate links to each other with last counterpunch board, is arranged with the grate plate that links to each other with back counterattack grate plate in the casing around the hammer dish.
Described upward counterpunch board is the last waveform counterpunch board that the bottom surface is provided with the waveform curved surface.
Described back counterattack grate plate is continuous the forming of counterpunch board by the seam of combing having of two sections arcs, and rear arc counterattack grate plate is fixed on the back counterattack frame, and the back is strikeed back frame and is fixed on the casing by back counterattack frame axle.
The described grate plate that is located in hammer dish periphery comprises the discharge grate plate of second periphery that is located in the hammer dish, and described discharge grate plate is by being bolted on the comb frame, and the comb frame is connected with casing by comb frame guiding mechanism.
Described comb frame guiding mechanism comprise many laterally be located in the axle sleeve of suit on comb frame axle on the comb frame, the comb frame axle, the adjusting bolt that is connected between axle sleeve and the casing constitutes, one end of described adjusting bolt is connected with axle sleeve, and the other end is anchored on the casing outside with nut.
The described grate plate that is located in hammer dish periphery also comprises the forward and backward shaping grate plate that is located in hammer dish upper semicircumference periphery, the upper edge of forward and backward shaping grate plate connects the lower edge of charging aperture and back counterattack grate plate respectively, and the rear and front end of described discharge grate plate is connected by forward and backward sealing device respectively with forward and backward shaping grate plate.
Be hung with the backgauge heavy curtain in the casing of described charging aperture inboard.
Described hammer dish top is provided with the buffering thick stick.
Single block hammer crusher of the present utility model in use, run-of-pit enters hammer dish and last waveform counterpunch board from charging aperture, counterattack crushing chamber between the rear arc counterattack grate plate, the tup that building stones are run up accelerates to very high peripheral speed, the strike by rotor under action of centrifugal force of building stones particle outwards flies out at a high speed, with last waveform counterpunch board and rear arc counterpunch board generation perfectly elastic impact, the stone that is crashed to pieces again with crusher chamber in other particles repeatedly from mutually the bump, grind, in the chamber, form turbulent flow, more near the crusher chamber inwall, the particle of stone is more little, speed is low more, in the near future the stone of degradedness just pass having the seam of combing rear arc counterattack grate plate and discharge grate plate draw off.60%-70% fragmentation bump generation mutually between building stones in the single block hammer crusher of the present utility model, thereby the wearing and tearing load of tup, liner plate, counterpunch board, grate plate has only the 20%-30% of conventional disintegrating machine, the harmful functional shift of tup, counterpunch board, grate plate, liner plate of in the past being used in a large number to wear and tear is the useful work of broken material, thereby compare crushing efficiency with conventional disintegrating machine and significantly improve, specific electric loading output obviously exceeds like product.
In addition, be provided with comb frame guiding mechanism between the comb frame of discharge grate plate of the present utility model and the casing, gap between discharge grate plate and the tup can wholely outside machine conveniently be regulated, guarantee that the service life and the crushing effect of wearing pieces such as tup, grate plate is in optimum state all the time.
In addition, charging aperture of the present utility model inboard is provided with and can prevents that building stones from oppositely sputtering the backgauge heavy curtain of charging aperture.
In addition, hammer dish of the present utility model top is provided with the buffering thick stick, and this buffering thick stick can cushion the speed of building stones when building stones fall, reduce the impact to the hammer dish, the rotor of protection hammer dish.
