Abstract
The utility model discloses a hammer-sheet crusher in the field of material crushing devices, which comprises a crushing chamber and a rotor arranged inside the crushing chamber. The crushing chamber includes a sieving sheet, a casing and a pressing sieve frame, the sieving sheet is mounted on the pressing sieve frame mounted on the casing, the sieving sheet surrounds two sides of the rotor and the outer periphery of the bottom of the rotor, and a feeding passage reserved on the upper portion of the sieving sheet is connected with a feeding port arranged on the casing. The rotor includes hammer frame plates arranged on a spindle at intervals, hammer sheets are mounted among the hammer frame plates via hammer sheet shafts, and electromagnets are mounted below the feeding port on two sides of the feeding passage. The rotor of the crusher cannot generate larger impact on connecting keys of the spindle with the hammer frame plates and a connecting key of a coupler and the spindle during speed reduction, and cannot cause abrasion of parts.
Description
Technical field
The utility model relates to the pulverizer in a kind of material-pulverizing device field, particularly a kind of hammer crusher.
Background technology
The hammer crusher that uses in existing grain, flour, the feedstuff industry is generally by support, rotor, compositions such as pulverizing chamber, motor, between motor and the rotor by the transmission of shaft coupling direct connection.Pulverizing chamber is made up of sieve sheet, casing and pressure screen frame (unit) etc., is enclosed in rotor periphery.Rotor is by main shaft, and multi-disc is installed on the hammer frame plate that main shaft is parallel to each other, and the bearing pin that is installed on the hammer frame plate is formed with the some hammer leaves that are installed on the bearing pin.Rotating speed is higher during the hammer crusher working rotor, and rotor all passes through dynamic balance check.Need to require use instead the sieve sheet of different size during general plant produced, and need to change after the hammer leaf wearing and tearing according to different formulations and finished product.These maintenance and operations etc. all need be shut down at pulverizer, carry out under the stationary rotor situation.When shutting down after the pulverizer work; the big and high rotational speed because of the rotor sole mass, rotor has bigger kinetic energy, and rotor has good dynamic balancing simultaneously; generally need to wait for that the long period rotor could stop fully, change spare part and attended operation etc. to be correlated with.Because the specification and the kind quantity of production feed are more, it is also comparatively frequent that it changes sieve sheet specification at most of feed factories, waits for that in this process rotor has stopped wasting a large amount of time, has largely reduced the production efficiency of factory.
In order to solve the long problem of rotor mill dwell time, a lot of solutions is also arranged on the market, increase brake gear at rotor main shaft one end or shaft coupling end, or directly select the shaft coupling of strap brake device for use, or the motor of select tape brake gear.Its weak point is: these brake gears all be by main shaft or with parts that main shaft is connected on apply damping torque to reduce rotor speed, the capital produces impact to the connecting key of main shaft and hammer frame plate or the connecting key at shaft coupling place, influences the service life of rotor or shaft coupling; Damping torque is produced by frictional force simultaneously, and its friction means needs often to change, and wastes time and energy.
The utility model content
The purpose of this utility model is longer in order to solve in the prior art rotor mill stalling time, and the problem that more existing deceleration schemes have influenced the service life of rotor and shaft coupling provides a kind of hammer crusher, make the stall at short notice of its rotor, moderating process can not produce wearing and tearing to parts.
The purpose of this utility model is achieved in that a kind of hammer crusher, it comprises the rotor that is provided with in pulverizing chamber and the pulverizing chamber, described pulverizing chamber comprises the sieve sheet, casing and pressure screen frame (unit), described sieve sheet is installed in presses on the screen frame (unit), press screen frame (unit) to be installed on the casing, the sieve sheet is enclosed in rotor both sides and bottom periphery, the feeding-passage that links to each other with the charging aperture that is provided with on the casing is left on sieve sheet top, described rotor comprises the hammer frame plate that is disposed on the main shaft, through hammer slice axis hammer leaf is installed between the hammer frame plate, described charging aperture below, and the both sides that are positioned at feeding-passage are equipped with electromagnet.
The utility model is installed in the feeding-passage both sides with electromagnet, by charging makes it produce magnetic force to rotor generation attraction formation damping torque to electromagnet, thereby rotor is decelerated to be stopped, compared with prior art, the beneficial effects of the utility model are: electromagnet can not produce greater impact to the connecting key of main shaft and hammer frame plate and the connecting key of shaft coupling and main shaft to the attraction of rotor; The attraction of hammer frame plate and hammer leaf generation and the gravity of hammer frame plate and hammer leaf are produced certain balance, its wearing and tearing to main shaft are reduced; Simultaneously, magnetic force is a kind of contactless force, also can additionally not produce heat and noise even apply the long period, and can not produce wearing and tearing to parts.
As further improvement of the utility model, described electromagnet is two left-right symmetry and the integral body of installing along the rotor length direction; The length of described electromagnet is less than or equal to the length that the hammer frame plate part is housed on the rotor, angled-90 °～90 ° of the direction of electromagnet generation magnetic force and rotor center, the magnetic force maximization that electromagnet is produced is used in the moderating process of rotor, strengthens the deceleration effect.
Description of drawings
Fig. 1 is the utility model assembling schematic diagram.
Wherein, 1 charging aperture, 2 electromagnet, 3 press screen frame (unit), 4 sieve sheets, 5 rotors, 501 hammer frame plates, 502 hammer leaves, 503 hammer slice axis, 6 pulverizing chamber, 7 casings.
The specific embodiment
As shown in the figure, be a kind of hammer crusher, it comprises the rotor 5 that is provided with in pulverizing chamber 6 and the pulverizing chamber 6, pulverizing chamber 6 comprises sieve sheet 4, casing 7 and pressure screen frame (unit) 3, sieve sheet 4 is installed in presses on the screen frame (unit) 3, press screen frame (unit) 3 to be installed on the casing 7, sieve sheet 4 is enclosed in rotor 5 both sides and bottom periphery, the feeding-passage that links to each other with the charging aperture 1 that is provided with on the casing 7 is left on sieve sheet 4 tops, rotor 5 comprises the hammer frame plate 501 that is disposed on the main shaft, through hammer slice axis 503 hammer leaf 502 is installed between the hammer frame plate 501, charging aperture 1 below, and the both sides that are positioned at feeding-passage are equipped with electromagnet 2, electromagnet 2 is two left-right symmetry and the integral body of installing along rotor 5 length directions, the length of electromagnet 2 also can equal to be equipped with on the rotor 5 length of hammer frame plate 501 parts less than the length that hammer frame plate 501 parts are housed on the rotor 5, angled 90 ° of the direction of electromagnet 2 generation magnetic force and rotor 5 centers.
During the utility model production work, need require to use instead the sieve sheet 4 of different size according to different formulations and finished product, and need to change after hammer leaf 502 wearing and tearing, all must under rotor 5 inactive states, change; After the shutdown; make it produce magnetic force for electromagnet 2 energisings rotor 5 is produced attraction to form damping torque; thereby rotor deceleration 5 within a short period of time is stopped; and can not produce wearing and tearing to parts, adjustment is adjusted by the electric current of electromagnet 2 can adjust its dwell time to the attraction of rotor 5.
