Abstract
A sealing structure of a bucket-wheel mechanism of a bucket-wheel stacker-reclaimer comprises a movable piece fixed on a wheel body of the bucket-wheel stacker-reclaimer, and a static piece detachably arranged on a material sliding plate of the bucket-wheel stacker-reclaimer. The movable piece and the static piece directly contact with each other to form a contact type motive seal. When the wheel body of the bucket-wheel mechanism is in circumferential rotation, the whole sealing structure of the bucket-wheel mechanism works, thereby ensuring that excess materials and tailings in a bucket provided with the bucket-wheel mechanism are prevented from falling to the lower surface of a belt conveyer through gaps between the wheel body and the material sliding plate, and therefore the problem of line deflection of a belt on the head portion of the belt conveyor is solved, operation environments are improved, material loss is avoided, and working efficiency is improved.
Description
Technical field
The utility model belongs to the bucket-wheel stacker reclaimer technical field, relates to the sealing arrangement of bucket-wheel stacker reclaimer bucket-wheel mechanism.
Background technology
It is the continuously high-efficiency appliance of loading and unloading of the ancestor of modern chemical industry sparetime university bulk material that bucket wheel machine is again bucket-wheel stacker reclaimer, has been widely used at present the stacking and taking operation in bulk cargo (ore, coal, coke, sandstone) the storage stock grounds such as harbour, harbour, metallurgy, cement, steel plant, coke-oven plant, coal storage plant, power plant.Have the characteristics such as efficient is high, degree of automation is high, operation cost is low.In recent years, along with the maximization in bulk material stock ground and the continuous maturation of automation and bucket-wheel stacker reclaimer manufacturing technology, bucket-wheel stacker reclaimer also progressively to maximizing and the automation direction development, is also had higher requirement to the performance of equipment material extracting operation simultaneously.
Bucket-wheel stacker reclaimer is when carrying out material extracting operation, bucket-wheel mechanism is done circumferentially to rotate, the coal tub of bucket-wheel mechanism is when improving material, because a variety of causes has no idea all to unload material clean, at this moment always clout or tailing are arranged in the coal tub, as shown in Figure 6, because accuracy of manufacture, equipment use the rear reasons such as distortion that produce, at the wheel body 1 of bucket-wheel stacker reclaimer with slip and exist apart from the gap between the flitch 2, the clout in the bucket-wheel stacker reclaimer coal tub or tailing Chang Congqi gap location are scattered.The clout or the tailing that are scattered not only pollute the environment, and make the operating environment variation, cause loss of material, more have part can be scattering on the lower belt of band conveyor, cause belt feeder at bucket wheel head sideslip, and operation brings difficulty to equipment high efficiency.
The utility model content
In order to overcome aforementioned technical problem, the purpose of this utility model is: a kind of sealing arrangement of bucket-wheel stacker reclaimer bucket-wheel mechanism is provided, utilizes this device can reduce or avoid clout or tailing in the bucket-wheel stacker reclaimer coal tub to be scattered, improve environment, reduce the loss of material, increase work efficiency.
In order to solve the problems of the technologies described above, the sealing arrangement of the bucket-wheel stacker reclaimer bucket-wheel mechanism that the utility model provides has the movement parts on the wheel body that is fixed in described bucket-wheel stacker reclaimer; Be removably installed in the static element on the slide flitch of described bucket-wheel stacker reclaimer; Described movement parts directly contacts with static element and forms the contact dynamic seal.When the wheel body of bucket-wheel mechanism rotates, form dynamic seal between movement parts and the static element, make the clearance seal between wheel body and the slide flitch, avoid material from its gap, to be scattered.
Further, the sealing arrangement of the bucket-wheel stacker reclaimer bucket-wheel mechanism that the utility model provides, described movement parts has at least one V-arrangement or U-lag, and described static element has the Contact Tooth with described V-arrangement or U-lag engagement, and described V-arrangement or U-lag and the engagement of described Contact Tooth consist of the contact dynamic seal.Adopt the engagement of V-arrangement or U-lag and Contact Tooth to consist of the contact dynamic seal, have sealing reliably, the characteristics that friction drag is little.
