Abstract

The utility model discloses a bucket elevator, which belongs to a material conveyer and comprises a machine seat, a machine case, a head cover case, a driver, a chain wheel, a chain and dustpans, wherein the chain wheel comprises a head wheel in driving rotation and a tail wheel in driven rotation, the head wheel is driven to rotate through the driver, the annular chain wound around the head wheel and the tail end is driven, further, a plurality of dustpans arranged at the outer side of the chain are driven to do reciprocating movement in the vertical direction, the dustpans are used for carrying materials to realize the vertical conveying of the materials, and the machine seat, the machine case and the head cover case are support elements and sealing elements for the elevator. The bucket elevator is characterized in that the outer circle diameter of the tail wheel is a little greater than the outer circle diameter of the head wheel, the angle speed of the dustpans while going around the tail wheel is a little smaller than the angle speed while going around the head wheel, and the defects that the charging materials are not full, the mixed material mixture ratio is damaged, a large amount of dust is caused, and the like because the dustpan speed is too high and the materials are scattered through collision during the material loading in the prior art are avoided. Compared with a bucket elevator in a critical material loading state, the bucket elevator has higher operation speed and production efficiency and is more favorable for environment protection and energy saving.

Description

A kind of bucket elevator

Technical field

The utility model relates to a kind of material conveying device, relates in particular to a kind of bucket elevator of the better effects if of feeding.

Background technology

At present, in the existing bucket elevator, material enters the support inner chamber by the inlet point of lower, drive great wheel by actuating device, chain and winnowing pan motion are advanced the material splendid attire in the winnowing pan, and vertical uplift is dished out by discharging opening to eminence, but powdery, graininess and little lump material, be widely used in metallurgy, chemical industry, the conveying of light industry raw material, especially in concrete dry powder mortar raw material manufacturing enterprise, bucket elevator is used to promote sand-lime, mixed materials such as dry powder and mortar, the density of each composition and grain size differ greatly in the material, therefore wherein density and the less raw material of particle then hit and looses even throw and kick up when mixed material is subjected to the bump of winnowing pan, destroyed the proportioning of mixed material, is unsealed as if inlet point, also can cause a large amount of dust to fly out, influence environment by inlet point.

Therefore, the problems referred to above do not occur in order to make the bucket elevator when filling with substance, and guarantee the production efficiency of gig, need bucket elevator is improved, making it the when filling with substance winnowing pan can be with lower cireular frequency contact material.

The utility model content

In view of this, the utility model provides a kind of bucket elevator, its winnowing pan has lower cireular frequency when walking around tail wheel, less to the material impacting of carrying, under the situation that guarantees productive output, the charging better effects if has been avoided in the charging process owing to the excessive foreign material such as a large amount of dust that cause of interaction force between winnowing pan and the material, have higher running velocity and production efficiency with respect to the bucket elevator under the critical state of charge, more help environmental protection and energy saving.

Bucket elevator of the present utility model, comprise the support, casing and the head case that are fixedly connected sequentially from bottom to top, be fixed in the actuating device on the described casing, cooperate with described actuating device transmission and be positioned great wheel on the casing, be positioned the tail wheel on the described support, be around in described great wheel and the annular link chain of tail wheel and transmission cooperation with it and several winnowing pans that are arranged at the annular link chain outside and captive joint, also be provided with holdback and tightening device with the tail wheel transmission link on the described support, the outside diameter of described tail wheel is more bigger than the outside diameter of described great wheel.

Further, the outside diameter D of described tail wheel ₁Outside diameter D with great wheel ₂Relation be: (D ₁-D ₂)/D ₂=a, wherein a ∈ (0,0.5).

The beneficial effect that the utility model reaches is: bucket elevator of the present utility model, its tail wheel outside diameter is more bigger than great wheel outside diameter, the cireular frequency of cireular frequency when making winnowing pan walk around tail wheel when walking around great wheel is smaller, avoided when filling with substance in the prior art because winnowing pan excessive velocities and material hit that the charging that causes of loosing is discontented, the mixed material proportioning is destroyed and drawback such as a large amount of dust, make bucket elevator have higher running velocity and production efficiency, environmental protection and energy saving in normal operation.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Fig. 1 is a structural representation of the present utility model, as shown in the figure: bucket elevator of the present utility model, comprise the support 1 that is fixedly connected sequentially from bottom to top, casing 2 and head case 3, be fixed in the actuating device 4 on the described casing, cooperate with described actuating device 4 transmissions and be positioned great wheel 5 on the casing 2, be positioned the tail wheel 6 on the described support 1, be around in the annular link chain 7 and several winnowing pans 8 that are arranged at annular link chain 7 outsides and captive joint of described great wheel 5 and tail wheel 6 and transmission cooperation with it, also be provided with holdback and tightening device with the tail wheel transmission link on the described support 1, it is characterized in that: the outside diameter of described tail wheel 6 is more bigger than the outside diameter of described great wheel 5.

In the present embodiment, the outside diameter D of described tail wheel ₁Outside diameter D with great wheel ₂Relation be: (D ₁-D ₂)/D ₂=a, a ∈ (0,0.5) wherein, the outside diameter of the tail wheel 6 of present embodiment is according to material attribute, mounting structure and satisfy the chain line speed COMPREHENSIVE CALCULATING gained of unit time operational throughput, gets (D ₁-D ₂)/D ₂=0.5, cireular frequency has reduced by 1/3 to make cireular frequency that winnowing pan walks around tail wheel when walking around great wheel.

In the present embodiment: described material is the dry powder and mortar raw material, comprise compositions such as cement, coarse whiting, quarz sand and rubber powder, the density and the grain size of each composition differ greatly, wherein density and the less raw material of particle then hit and looses even throw and kick up when mixed material is subjected to the bump of winnowing pan, destroy the homogeneity that mixed material mixes, also can cause a large amount of dust to fly out, influence environment, therefore the bigger tail wheel of diameter is set by inlet point.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
