设备简介Equipment Introduction

LMDT系列斗式提升机是我公司引进国外同类产品先进技术开发的产品，在各工业国家，这类输送机广泛用于输送量较大的粉状和小颗粒状物料的提升。它适用于提升粉状和小颗粒状物料，如：水泥、煤粉、破碎后较细的矿石等。

The LMDT series bucket elevator is a product developed by our company by introducing advanced technology from similar foreign products. In various industrial countries, this type of conveyor is widely used for lifting large amounts of powdered and small granular materials. It is suitable for lifting powdery and small particle materials, such as cement, coal powder, and finer ore after crushing.

应用物料Application materials

斗式提升机主要适用于输送粉状、粒状、小块状的低磨琢性物料，如：煤、水泥、碎石、砂子、化肥、粮食等温度不超过250℃的物料。

The bucket elevator is mainly suitable for conveying low grinding materials such as coal, cement, crushed stones, sand, fertilizers, grains, etc. with a temperature not exceeding 250 ℃.

工作原理operational principle

LMDT板斗式提升机由运行部件、驱动装置、上部装置、中部机壳、下部装置组成。

1.运行部件──由料斗和套筒滚子链组成。

2.驱动装置──由驱动平台、驱动组合、传动链组成。驱动组合通常由ZSY硬齿面减速机（或JZQ减速机）、YOX液力偶合器、Y系列电机、XWD减速机、电磁离合器（或手动离合器）组成。

3.驱动装置分左装和右装两种。分别与提升机左、右装对应。

4.左装：为人面对进料口，驱动装置组合和传动链轮在左侧。

5.右装：为人面对进料口，驱动装置组合和传动链轮在右侧。

6.上部装置──有上部机壳（安装有轨道）、上罩、卸料口（装有防回料板）、头轴装配、逆止器等部件。

中部机壳──分为与上部装置联接的带支撑中间节、带检视门中间节、标准中间节（均为2.5米高）和1米、1.5米高的非标准中间节，使得提升机能以0.5米一档来获得不同的高度。

下部装置──包括下部机壳、进料口、尾轴装配、张紧装置。

The LMDT bucket elevator consists of operating components, driving devices, upper devices, middle casing, and lower devices.

1. Operating components - composed of a hopper and a sleeve roller chain.

2. Driving device - composed of driving platform, driving combination, and transmission chain. The drive combination usually consists of ZSY hard tooth surface reducer (or JZQ reducer), YOX hydraulic coupling, Y series motor, XWD reducer, electromagnetic clutch (or manual clutch).

3. The driving device is divided into two types: left mounted and right mounted. Corresponding to the left and right installation of the elevator.

4. Left installation: Facing the feeding port, the driving device combination and transmission sprocket are on the left side.

5. Right installation: Facing the feeding port, the driving device combination and transmission sprocket are on the right side.

6. Upper device - includes upper casing (with track installed), upper cover, discharge port (with anti backflow plate installed), head shaft assembly, backstop, and other components.

Middle casing - divided into a middle section with support connected to the upper device, a middle section with inspection door, a standard middle section (all 2.5 meters high), and non-standard middle sections of 1 meter and 1.5 meters high, allowing the lifting function to achieve different heights in increments of 0.5 meters.

Lower device - including lower casing, feed inlet, tail shaft assembly, and tensioning device.

设备特点Equipment characteristics

l 密封性好，环境污染少。

l 操作维修方便、易损件少。

l 使用成本低，由于能耗低和维修少，使用成本极低。
