三、结构原理

iii. structure and working principle

隔膜式跳汰机，如图一所示，它上部为长方形，而下部为角锥形的洗矿槽1与2，两个相连，装在机架3上构成一体，各槽各有跳汰区a、b和隔膜区c，在a、b两区之间用不到底的隔板分开。各槽共助于同一传动装置4，配水活瓣5，如图二所示，及补助水管6，跳汰区上部跳汰过程靠隔膜往复运动造成水的鼓动来进行矿物分选，隔膜下冲时，在筛板下面供给补助水，补助水用配水活瓣5来调节，活瓣5与隔膜7的动作是同步的，当隔膜下降时活瓣关闭，水不进入跳汰机中，但隔膜上升时，活瓣启开因此，减少了跳汰机内下降水流的作用。

as is shown in figure 1, the top of the diaphragm jig is rectangular and the bottom of it is pyramid-shaped washing trough 1 and washing trough 2. these washing troughs are linked together and installed on frame 3 to become one. there are jigging area a, jigging area b, and diaphragm area c in each trough. jigging area a and jigging area b are separated by a division plate that does not reach the bottom. each trough serves the same one transmission device 4 and is e with water valve 5 as shown in figure 2 as well as water pipe 6. the jigging process in the upper side of the jigging area causes the agitation of water through the reciprocating motion of the diaphragm, so as to realize mineral separation. when the diaphragm moves downward, it supply supplement water under the sieve plate. the supplement water is adjusted through the water valve 5. the water valve 5 and diaphragm 7 operate synchronously. when the diaphragm moves downward, the water valve is shut and water does not enter the jig. when the diaphragm moves upward, the water valve is opened. therefore, the function of descending water current in the jig is reduced.

槽体是灰口铁铸造而成，隔膜7乃固定在槽体水平铁垫8上密封而不漏，隔膜借助于偏心连杆9、10及隔膜连杆11与杠杆12相连接，并由杠杆12获得往复运动，因而在工作室造成相应的鼓动，杠杆又与套在轴13上的偏心连杆相连接，轴14由电动机15，通过三角皮带16及皮带轮17代动。

the trough is cast by gray pig iron. the diaphragm 7 is fixed on the horizontal iron washer 8 of tank which is well sealed. the diaphragms are connected through the eccentric links 9 and 10 as well as diaphragm 11 and lever 12. they do reciprocating motion through lever 12. therefore, corresponding agitation is caused in the working chamber. the lever is then connected with the eccentric link covered on the shaft 13. the shaft 14 is driven by motor 15 through v-belt 16 and belt pulley 17.

各室的高度不同而成阶梯形，原矿经给矿槽18送入跳汰室，基于矿物比重不同，被水驱动而分别排出，沉入下层的是比重大的矿物经过截门19胶管20（胶管长度需根据实际使用条件决定）进入排矿瓶21，在上层比重小的矿物沿溢流槽22流出。

due to different heights of each working chamber, the raw ores are fed into the jigging room after passing the feeding trough. they are discharged out after driven by water due to different specific gravities of ores. the ores sinking into the lower layers have large specific gravities. they pass the stop valve 19 and rubber hose 20 (the length of rubber hose depends on the actual service conditions) and then enter the ore discharging bottle 21. the ores at the upper layer with small specific gravity flow out along the overflow channel 22.

四、安装与试验

4.0 installation and testing

xct隔膜式跳汰机安装在车间平地上或案台上，若为辅助设备时，或与其它设备相配置时，应考虑到给矿，排矿及检查修理等工作的方便，跳汰机安装地点应有220/380伏的电源，补助水压为0.6-2kg/㎝2.

xct diaphragm jig is installed on flat ground or table in the workshop. if it is an auxiliary e, or used with other e, then the installation point shall be provided with 220/380v power source and 0.6-2kg/㎝2 water pressure to facilitate ore feeding, ore discharge, inspection and repair.

当跳汰机安装完成后应以水平仪进行水平的检查不得有歪斜现象，接通电源进行空车试验不少于2小时，如一切顺利则进行负荷试车，负荷试车时应以正常操作规程进行，试车结果合格后，再正式投入使用。

after installation, use a spirit level to check levelness of the diaphragm jig to avoid inclination. connect to power and perform no-load trial for at least 2 hours. if the no-load trial is smooth, then on-load trial run shall be done as per normal operating procedures. after the trial run results are acceptable, the e can be put into use.

每当机器移动，一定要将机器固紧木板上。

before movement of the machine, it must be fixed securely on the wooden plate.

五、使用与调整

5.0 use and adjustment

隔膜式跳汰机的两个槽是相等的，而安装高度不同，以便易于从第一室流入第二室的连续作业，矿物原料由给矿槽送入跳汰室，籍隔膜作往复运动而获得鼓动水流，矿物借水力作用而移动。因此，隔膜的冲程大小有很大的意义。

diaphragm jig has two equal chutes, but the installation height is different so as to ensure continuous working from the first chamber into the second chamber. raw ore materials are fed into the jig chamber through the feeding chute and move under the force of water flow produced by movement of the diaphragm. therefore, stroke of the diaphragm is of great significance.

冲程和冲次主要决定于被处理物质的粒度被处理物质越粗，则所需冲程愈大，而冲次愈少，调节隔膜冲程大小时，要考虑到所采用的冲程能保证人工床有很好的活动性，当其他条件相同时，厚的人工床或高的尾板需要较大的冲程以便能克服较大的阻力。

stroke and times of strokes are mainly dependent on particle size of processed substances. higher particle size of the substance will need higher strokes and lower frequency of stroke. adjusting stroke of the diaphragm shall take into consideration that the adopted stroke can ensure good movement of the artificial bed. if other conditions are same, then thick artificial bed or high tail plate needs higher stroke so as to overcome large resistance.

隔膜下冲时人工床在某一时期内，应当成为浮悬状态，不但不破坏其完整性，当转为吸入行程时，吸力不应大得使矿粒过分紧密。

when the diaphragm rushes down, the artificial bed shall be under a suspension status within a certain period. this will not break its integrity. when it transforms to suction travel, the suction force shall not so large to create excessively tightening particle size.

为调节隔膜冲程，松开偏心瓦螺钉，调到所需距离后，再重新紧固，同时应注意两个隔膜的冲程应相等。如图三

to adjust stroke of the diaphragm, loosen the eccentric bush screw and retighten it after it is adjusted to needed distance. meanwhile, make sure that stroke of the two diaphragm shall be equal as shown on fig.3.

所选矿物达到要求或玻璃瓶注满矿物后，可将截门关闭，将排矿瓶中矿物取出。

after separated ores meet re or the glass bottle is filled fully with ores, the stop valve can be closed and the ores in the bottle can be taken out.

六、润 滑
