Background technology
Rotary feeder claims rotovalve or flapper again, and rotary feeder can carry out the material equal and quantitative to be carried, and is a kind of gordian technique equipment in the air-transport system.Usually the structure of rotary feeder partly is made up of housing, end cap, impeller etc., impeller rotates in columnar housing during work, material falls between the blade set on the impeller in the space from the top hopper by the self gravitation effect, material is discharged to the discharging opening that lower housing portion arranges with the rotation of impeller, the bottom of discharging opening connects accelerating chamber, the material that falls mixes with air-flow in accelerating chamber, delivers in the pipeline under the effect of pressure and air-flow.
Usually rotary feeder is in the process of transmission material, can wear and tear in the impeller of loader and the inside of housing, especially when being applied to the wearability mass transport, the wearing and tearing of rotovalve are particularly serious, the rotovalve severe wear can cause sealing effectiveness poor, the equipment inverted ventilation is serious, problems such as shortening in service life.Therefore the product of design and this operating mode of exploitation adaptation becomes inevitable.
The utility model content
The technical matters that the utility model solves has provided the wear-resisting rotary feeder that a kind of rotor-end is worn labyrinth seal structure, it is poor that this utility model has overcome the existing rotor end-face sealing of existing rotary feeder, easy to wear, service life is short, the problem of inverted ventilation takes place easily, and it has functions such as anti-sticking, wear-resistant, anti-middle pressure.
For solving the problems of the technologies described above, the wear-resisting rotary feeder of the utility model, it is characterized in that, comprise inlet point, discharging opening, housing and the rotor that is horizontally installed in enclosure interior, the two ends of described housing are provided with end cap, end cap is by the both sides of bolt in housing, and the inner wall surface of described housing is coated with one deck wear-resistant coating; Described rotor comprises impeller and rotating shaft, rotating shaft is arranged at the centre of impeller, the cylindrical position built-up welding that described impeller contacts with material has one deck wearing layer, the two ends of described impeller are provided with labyrinth seal structure, and there is one deck wearing layer at the cylindrical position that described labyrinth seal structure contacts with material also built-up welding.
Be provided with the two V mouths of feed anti-sticking in the described inlet point.
Be provided with discharging anti-sticking V mouth in the described discharging opening.
The beneficial effects of the utility model are:
1. the utility model has fundamentally solved the existing technological deficiency of existing rotary feeder, and the rotor end-face leak tightness is poor when having overcome common rotary feeder the wearability material being transmitted, the problem of serious wear.It has performances such as good anti-sticking, wear-resistant, anti-middle pressure, this wear-resisting rotary feeder better tightness with respect to common rotary feeder, and abrasion resistance properties is higher, longer service life.
2. this wear-resisting rotary feeder is in the Structured Design of the labyrinth packing of two ends of rotor face place employing, strengthened the sealing effectiveness of rotor end-face, actv. reduced in transmission material process, take place from the rotor end-face inverted ventilation, cause the not generation of smooth phenomenon of material transmission, promoted the pressure Applicable scope of rotary feeder, made that rotary feeder force applications scope is higher.
3. this wear-resisting rotary feeder has adopted anti-sticking, the anti-Structured Design of shearing respectively at inlet point and discharging opening place, actv. has reduced the generation that impeller is stuck and material is sheared phenomenon that takes place in transmission material process, enlarged the rotary feeder field of application, made that the rotary feeder field of application is wider.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation;
Fig. 2 is the A view of Fig. 1;
Fig. 3 is the structural representation of rotor;
Fig. 4 is the longitudinal sectional view of rotor;
Among the figure: 1-inlet point, the two V mouths of 11-feed anti-sticking, 2-discharging opening, 21-discharging anti-sticking V mouth, 3-housing, 4-rotor, 41-impeller, 411-wearing layer, 412-labyrinth seal structure, 42-rotating shaft, 5-end cap.
The specific embodiment
Shown in Fig. 1-4, a kind of rotor-end of the utility model is worn the wear-resisting rotary feeder of labyrinth seal structure, it comprises inlet point 1, discharging opening 2, housing 3 and the rotor 4 that is horizontally installed in enclosure interior, the two ends of described housing 3 are provided with end cap 5, end cap 5 is by the both sides of bolt in housing 3, the inner wall surface of described housing 3 is coated with one deck wearing layer 411, what the wearing layer of the inner wall surface of described housing adopted is the high-abrasive material of high hard, can improve the resistance to abrasion of inner walls like this, avoided that inwall frequently contacts with material in the material transmission course, the problem of inner walls serious wear takes place.
