Abstract

The invention relates to an elevator bucket conveyor test device and method. A distribution device is arranged under a discharge opening of an elevator bucket conveyor, a first discharge outlet and a second discharge outlet which are switchable are arranged in the bottom of the distribution device, and a first weighing hopper and a second weighing hopper are arranged under the discharge outlets respectively. Two circulatory chutes are arranged below the weighing hoppers respectively, a storage hopper is arranged under each circulatory chute, and each storage hopper is located over a feed opening of the elevator bucket conveyor. The elevator bucket conveyor test method includes switching the distribution device to the first discharge outlet or the second discharge outlet circularly, and acquiring accurate material weight by means of static weighing so as to obtain average flow rate within a period of time. By the aid of the circulatory static weighing method, high-precision instantaneous flow rate of material conveying and accumulated flow rate can be obtained. Therefore, the elevator bucket conveyor can be subjected to optimization design according to test data, conveying performance is improved, and time between failures is prolonged. The test device and the test method can be used for carrying out calibration test of the conveying performance before delivery.

Description

technical field [0001] The invention relates to the field of conveying test devices, in particular to a test device and method for a lifting bucket conveyor. Background technique [0002] Elevating bucket conveyor is a very widely used conveying equipment, also known as bucket elevator. Lifting bucket conveyors can be divided into: belt type bucket elevator (DT), chain type bucket elevator (TH) and plate chain type elevator (NE) according to the structure. Belt-type bucket elevator is suitable for conveying normal temperature powder, such as dry powder mortar, dry-mixed mortar, thermal insulation mortar, ready-mixed mortar, admixture, joint agent, interface agent, putty powder, chemical fine powder, economical and practical, the disadvantage is that the belt It is easy to go off track and needs frequent adjustments. Plate chain and ring chain bucket elevators adopt single-row or double-row chains, which are suitable for vertically conveying powdery, granular and small lump...
