Description

Evenly feeding device of pulverizer

Technical field

The present invention relates to the pulverizer field, relate in particular to a kind of evenly feeding device of pulverizer.

Background technology

Usually, the production capacity of pulverizer becomes the first power proportional relation with factors such as rotor mill length, rotor speeds, the pulverizer that production capacity is big more, and its rotor length is long more.But the conveyer ability but becomes the quadratic power proportional relation with the ribbon conveyer bandwidth, and bandwidth has determined materials flow width on the conveyer belt.Rotor mill length is always big than ribbon conveyer bandwidth and materials flow width under the normal condition, and rotor mill length that production capacity is big more and conveyer bandwidth differ big more.Can occur material under the on-the-spot practical condition and concentrate and cause the tup wearing and tearing uneven, and the problem that reduces smashing fineness and disposal ability.Frequent dimension is examined, and has not only increased the use cost of enterprise, has also increased workman's working strength, has influenced workers ' health.

The subject matter that the pulverizer of no even material feeding device exists is: the materials flow width that enters pulverizer obviously is narrower than the rotor length of pulverizer, and the materials flow uneven thickness, and it is thin to be the thick middle both sides.Directly cause middle part tup rapid wear, the two ends tup does not have wearing and tearing substantially or weares and teares lessly, has increased repair rate.

Part factory is with the built-up welding of high manganese welding rod to the treating method of the tup of mild wear, and is not only time-consuming, also workers ' health had a significant impact, and other many factories are whole replacings to the treating method of wearing and tearing tup, and cost is bigger.So supplied materials bed of material inequality has increased the use cost of enterprise's pulverizer largely.

Summary of the invention

The purpose of this invention is to provide a kind of thickness of feed layer homogenising that enters pulverizer, evenly feeding device of pulverizer that bed of material width strengthens of making.

To achieve these goals, the present invention is by the following technical solutions:

Evenly feeding device of pulverizer comprises adjustable materials flow baffle plate, adjustable deflector, casing, and adjustable materials flow baffle plate is arranged on casing top, and adjustable materials flow baffle plate top is provided with hinge, and hinge is arranged on the fixed axis, and the bottom is provided with the positioner of adjustable-angle; Adjustable deflector is arranged on lower box, its tilt adjustable.

Described adjustable materials flow baffle plate bottom is provided with bolt, realizes the angular adjustment location by the circular arc strip hole that bolt inserts on the casing.

Described adjustable deflector bottom is provided with a sleeve, and top is provided with one or more sleeves, is fixed on teasing and ridicule up and down between the knothole of being provided with on the casing, the tilt adjustable of adjustable deflector by latch.

This adjustable tripper is arranged in the chute, comprises cone, threaded adjusting handle, the nut of being with base plate, and the cone of band base plate is arranged in the chute by threaded adjusting handle, nut.

Compared with prior art, the beneficial effects of the utility model are: the materials flow layer thickness homogenising, the materials flow width that enter pulverizer are broadened, compare with traditional directly being connected by chute, the loss homogenising of the tup of pulverizer, not only reduce the number of times of changing and overhauling tup, reduce use cost, but also make crushing effect better.For beater grinder, especially reversible beater grinder because the cutting into position of adjustable material all in one piece stream of the present invention and tup is avoided the contrary tup direction of motion incision of materials flow, can prevent effectively that the top chute from stopping up in addition.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:

See Fig. 1, Fig. 2, evenly feeding device of pulverizer, comprise adjustable deflector 2, adjustable materials flow baffle plate 3, casing 4, chute 1 with adjustable tripper is connected with casing 4, adjustable materials flow baffle plate 3 is arranged on casing 4 tops, adjustable materials flow baffle plate top is provided with hinge 8, and the bottom is provided with the bolt 9 of adjustable-angle, realizes the angular adjustment location by the circular arc strip hole 16 that inserts on the casing 4.Adjustable deflector 2 is arranged on casing 4 bottoms, and its underpart is provided with a sleeve 10, top be provided with one or more sleeves 10 ', be fixed on the casing 4 between the two rows adjustment hole 7 that is provided with by latch 6.

Chute 1 top is connected with belt feeder, and casing 4 bottoms are connected with pulverizer.Materials flow by chute 1 impacts earlier on the adjustable materials flow baffle plate 3, and freely falling body carries out entering pulverizer again after the homogenising second time to adjustable deflector 2 subsequently.Density and the angle that can regulate adjustable deflector 2 by the two socket pin-and-holes of reserving on the casing 47, the angle of adjusting adjustable materials flow baffle plate 3 by the circular arc strip hole 16 on the casing 4 is to change the drop point of materials flow on adjustable deflector 2.

See Fig. 3, Fig. 4, adjustable materials flow baffle plate 3 upper end hinges 8 are arranged on the fixed axis, and the lower end is provided with angle adjustable bolt 9.Fixed axis with top is a pivot, can by on the degree of tightness angle adjustable bolt 9 fixedly the nut of usefulness come butterfly angle to regulate the discharging point of materials flow on adjustable deflector 2.

See Fig. 5, Fig. 6, adjustable deflector 2 bottoms are provided with a sleeve 10, one or more sleeves 10 can be arranged in top, in Fig. 1 embodiment, latch 6 passes the sleeve 10 interior fixations that rise on the casing rise knothole 7 insertion water conservancy diversion plate bodys, lower sleeve portion 10 can move left and right upper latch 6 fixedly the time be adjusted the angle of adjustable deflector 2 in the corresponding different upper sleeve 10 in the position, the left and right sides of casing 4 overpunchings, works to regulate materials flow and spreads.

See Fig. 7, adjustable tripper 5 comprises cone 11, threaded adjusting handle 12, the nut 13 of being with base plate 14, and the cone 11 of band base plate is arranged on the chute base plate 15 by threaded adjusting handle 12, nut 13 trapezoidal profile.Can rotate or move left and right by the nut 13 on the degree of tightness threaded adjusting handle 12.Can be by the position of calculating or the selected adjustable tripper 5 of empirical value.Bore rectangular opening on the chute base plate 15 and play fixing and fine setting effect.The homogenising first time is carried out in the supplied materials materials flow in this section chute 1, bed of material width is widened, thickness carry out certain evenly.

Advantage of the present invention is: owing to introduce the present invention between supplied materials belt and pulverizer, make that the materials flow that enters pulverizer is layer thickness homogenized, stock flow width broadens. Directly be connected and compare with traditional chute that passes through, the loss homogenising of the tup of pulverizer not only reduces and changes and the number of times of maintenance tup, reduces use cost, but also has improved crushing effect.

In addition for beater grinder, especially reversible beater grinder, because the existence of even material feeding device straight section height and the cutting into position that adjustable materials flow baffle plate can be adjusted materials flow and tup, avoid the contrary tup direction of motion incision of materials flow to clash into it and pulverize, prevent the top chute blocking.
