結(jié)構(gòu)簡(jiǎn)介

Structure

本機(jī)由勵(lì)磁系統(tǒng)、傳動(dòng)機(jī)構(gòu)、給礦系統(tǒng)及產(chǎn)品清掃收集部分所組成。

This machine consists of excitation system, transmission mechanism, feeding system, as well as product cleaning and collection part.

1、勵(lì)磁系統(tǒng)：

1. Excitation System

由固定磁極，輥?zhàn)有D(zhuǎn)磁極和裝在兩者之上的勵(lì)磁繞組及激磁直流電源所組成，上下兩磁極平行排列。由直徑為120毫米兩個(gè)輥?zhàn)优c下部平面磁極構(gòu)成封閉磁回路。兩磁極的工作間距可通過增減墊板進(jìn)行調(diào)整。通過調(diào)節(jié)高壓器的電壓使硅元件供給固定勵(lì)磁繞組和經(jīng)電刷供給輥?zhàn)有D(zhuǎn)磁極勵(lì)磁繞組的直流電流，可從需平滑地升至額定值2安培，為適應(yīng)不同礦種的選別需要本機(jī)磁場(chǎng)強(qiáng)度范圍可分為強(qiáng)磁場(chǎng)和弱磁場(chǎng)兩種，由面板上磁場(chǎng)選擇開關(guān)進(jìn)行選擇。當(dāng)分選磁間距為4毫米，磁場(chǎng)選擇開關(guān)置“強(qiáng)磁場(chǎng)”位置，激磁電流為2安培時(shí)****磁場(chǎng)強(qiáng)度不小于14000奧斯特（1110RA/m）。

It is composed of fixed magnetic pole, roller rotation magnetic pole, as well as exciting winding and exciting DC power supply installed above them. The upper and lower magnetic poles are parallel arranged. Two rollers with the diameter of 120mm and the lower magnetic poles constitute closed magnetic circuit. The working distance between the two magnetic poles can be adjusted through the increase or decrease of base plates. Through the adjustment of the voltage of high-voltage machine, the DC current supplied to fixed exciting winding and supplied through electric brush to exciting winding for rollers to rotate magnetic pole can be increased to the rated value 2A smoothly. To meet the requirement for the separation of different types of ore, the magnetic field of this machine can be divided into high-intensity magnetic field and low-intensity magnetic field according to intensity, which can be selected through the magnetic field selection switch on the panel. When the separation magnet distance is 4mm, the magnetic field selection switch is put in the position of “high-intensity magnetic field”. When the excitation current is 2A, the maximum magnetic-field intensity is not lower than 14,000Oe (1,110RA/m).

2、傳動(dòng)機(jī)構(gòu)：

2. Transmission Mechanism

直流電機(jī)經(jīng)蝸輪減速機(jī)減速，傳動(dòng)輥?zhàn)有D(zhuǎn)磁極，旋轉(zhuǎn)磁極的轉(zhuǎn)速為55轉(zhuǎn)/分，為了減小電機(jī)的體積，采用直流電機(jī)用硅元件半波整流供電。

After the working speed of DC motor is reduced through the worm reducer, the motor drives the roller to turn the magnetic pole. The rotating speed of the magnetic pole is 55 R/min. To reduce the size of motor, thyristor half-wave rectification current for DC motor can be adopted for power supply.

3、給礦系統(tǒng)

3. Feeding System

由電磁振動(dòng)給礦器，儲(chǔ)礦漏斗和給礦錐體及擋板所組成。

The feeding system consists of electromagnetic vibration feeder, storage hopper, feeding cone, and baffle.

電磁振動(dòng)給礦器可以通過調(diào)節(jié)面板上左右二個(gè)線繞電位器，以控制電磁振動(dòng)給礦器的振幅，以適應(yīng)不同礦粒的需要。

The electromagnetic vibration feeder can adjust the two wire-wound potential meters (one is on the left and the other is on the right) on the adjusting panel to control the vibration amplitude of electromagnetic vibration feeder, for ores of different granular sizes.

為了調(diào)節(jié)給礦速度，可以選用具有不同大小給礦口的給礦錐體即可實(shí)現(xiàn)。

To regulate the feeding speed, feeding cones with mouths of different sizes can be selected.

正常給礦時(shí)，擋板調(diào)至約45度的傾斜度，以便使礦流均勻分散至給礦槽內(nèi)。若中途需停止給礦，將擋板提至水平靠近給礦口時(shí)，即可停止給礦。

During normal feeding, adjust the position of baffle to keep it at a tilting angle of about 45°with the ore so that the ore current can be evenly dispersed in the feed chute. If feeding needs to be suspended, raise the baffle until it gets close to the feeding mouth horizontally.

4、產(chǎn)品清掃收集部分：

4. Product Cleaning and Collection Part

由產(chǎn)品接收溜槽，分離板，重錘清掃刷和盛礦容器所組成。

This part consists of receiving chute, separating plate, counter weight brush cleaner, and ore containers.

在產(chǎn)品接收槽的中部，有一分離隔板，被吸引于輥?zhàn)由系拇判援a(chǎn)物，經(jīng)隔板順溜礦槽排入磁性產(chǎn)物盛礦容器中，分離隔板的傾斜度可通過擰動(dòng)槽一側(cè)的手柄即可調(diào)節(jié)，非磁性產(chǎn)物經(jīng)下部溜礦槽非入另一盛礦容器中。

There is a separating plate in the center of the receiving chute. The magnetic materials absorbed on the rollers are discharged into the ore container of magnetic materials through the separating plate along the chute. The gradient of the separating plate can be adjusted through pulling of the handle at one side of the chute. The non-magnetic materials flow into another ore container after passing the lower chute.
