TH and HL bucket elevators are suitable for vertically conveying powdery, granular and small block materials with high abrasiveness, such as grain, coal, cement, crushed ore, etc. The maximum conveying height is 40m, and its characteristics are: simple structure, stable operation, scooping-type loading, mixed or gravity unloading, combined sprocket for rim pigment, easy to replace, special treatment of sprocket rim, long service life, lower part If the gravity automatic tensioning device is used, it can maintain a constant tension and avoid slipping or de-chaining. At the same time, when the hopper encounters resistance, it has a certain tolerance to effectively protect the moving parts, and the material temperature does not exceed 250 ℃. TH type presses The standard design and manufacture of JB3926-85 "Vertical Bucket Elevator" should be used first. Except for the connection size, the chain, sprocket and tensioning device of the HL bucket elevator are the same.

Note: 1. The bucket volume in the table is the calculated bucket volume, and the conveying volume is calculated according to the filling factor of 0.6.
2. Application of TH type bucket elevator hopper: ZH-medium-deep bucket: conveying wet viscous materials, such as sugar, wet fine sand, etc.
Sh-deep bucket: conveying powdery to small block materials, such as cement, sand, coal, etc.
3. The use of HL type bucket elevator hopper: Q-shallow round bottom hopper: conveying materials that are wet, easy to agglomerate, and thrown out, such as wet sand, wet coal, etc.
S-deep round bottom hopper: conveying dry, loose, loose and easy to throw materials, such as cement, coal, crushed stone, etc.
4. Calculation of tensioning force: G=40+0.232Q*H In the formula: Q conveying capacity (t/h) H-lifting height (mm) G-tensioning force (Kg)
