Abstract
The utility model relates to an adjustable air lock feeding valve which comprises a shell, a rotor, a rotor blade end plate, a wear-resisting plate, a base plate and a bolt. The adjustable air lock feeding valve is characterized in that a bolt hole in the rotor blade end plate is a long hole, a rubber plate is clamped between the rotor blade end plate and the wear-resisting plate, and the front end of the rubber plate is in contact with the inner wall of the shell. The adjustable air lock feeding valve has the advantages of good sealing effect, good air lock effect, no blocking, no bonding, wear resistance, flexible adjustment of a gap between the wear-resisting plate and the shell, reliability in use, convenience in maintenance, and saving of time, electricity and labor. The worn rubber plate can be changed, and the whole valve can be repeatedly repaired, so that the maintenance cost of workers is reduced, the valve can be repeatedly used and has a long service time, the cost of the valve is reduced, and economic benefits are improved.
Description
Technical field
The utility model relates to a kind of adjustable lock feeding valve, particularly a kind of slag vertical-mill feeding valve, belongs to slag vertical-mill feeding valve field.
Background technology
Feeding valve is one of main device of slag vertical-mill feeding material, in Vertical Mill production operation process, whether all even lock wind of feeding, can stablize to the operating mode of grinding machine that to play very important effect (as excessive in feeding fluctuation and leak out serious, can cause that in mill, the bed of material is unstable, cause level, the vertical vibration aggravation of grinding machine, consume will be increased), so normally whether the stable working of feeding equipment, seems in the Vertical Mill production system particularly important.Existing feeding valve is made of housing and the rotor that is installed in housing, and the front end of rotor blade is end plate, is fixed with wearing plate and backing plate in the both sides of end plate with bolt.Because the bolt hole on end plate is circular hole, bolt position is fixed, so the position of wearing plate is also fixed, good in order to make valve seal, the inwall of housing is close in the end of wearing plate, but wearing plate is that rigidity contacts with inner walls, and sealing is limited.Often run in production process that feeding valve work badly causes that feeding is irregular, the feeding valve rotor blade is caused Vertical Mill vibration parking phenomenon by the stuck obstruction of material, and cause wearing plate and inner walls rapid wear, the slag vertical-mill shutdown maintenance, maintenance cost is high.
Summary of the invention
The purpose of this utility model be when overcoming feeding valve leak sealing and charging rotor blade by the foot phenomenon not such as stuck obstruction of material, provide a kind of good airproof performance, wearing plate and the body clearance can flexible modulation, stuck clogging does not appear, wearing plate wearing and tearing are little, maintenance less, adjustable lock feeding valve that the slag vertical-mill shutdown times is few.
The purpose of this utility model is realized by following mode:
The utility model comprises housing, rotor, rotor blade end plate, wearing plate, backing plate, bolt, it is characterized in that: the bolt hole on the rotor blade end plate is slotted hole, accompany rubber slab between rotor blade end plate and wearing plate, the front end of rubber slab contacts with inner walls.
The utility model has the advantages that: owing to accompanying rubber slab between end plate and wearing plate, rubber slab and inner walls are flexible contact, and wearing plate and inner walls just can keep certain interval, so not only improved the sealing of feeding valve, and not wearing and tearing between wearing plate and inner walls, wearing plate and inner walls only are subjected to the wearing and tearing of material, so wear extent greatly reduces; Bolt hole on end plate is that slotted hole makes wearing plate and the shell gap can flexible modulation, stuck clogging do not occur; And reduced the slag vertical-mill shutdown times, reduced artificial maintenance cost, reduced cost, improved economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of rotor blade end plate.
The specific embodiment
With reference to accompanying drawing, the utility model comprises housing 1 and the rotor 7 that is installed in housing, the front end of rotor blade is rotor blade end plate 2, bolt hole 8 on rotor blade end plate 2 is the slotted hole of 20*13mm, the both sides of rotor blade end plate 2 are fixed with wearing plate 5 and backing plate 3 with bolt, rotor 7, rotor blade end plate 2, wearing plate 5, backing plate 3, bolt 4, bolt hole on end plate is slotted hole, accompany rubber slab 6 between the leading portion of rotor blade end plate and wearing plate, the front end of rubber slab 6 contacts with housing 1 inwall.
Adopt feeding valve of the present utility model have lock wind effective, not jam, sizing, wear-resisting, wearing plate and shell gap can flexible modulation, use reliable, easy to maintenance, the power saving that saves time is laborsaving, can change after the rubber slab wearing and tearing, whole valve body can repeat to repair, and repeatedly uses, service time is long, realizes the purpose of cost efficiency.
