三、結構原理

III. Structure and Working Principle

隔膜式跳汰機，如圖一所示，它上部為長方形，而下部為角錐形的洗礦槽1與2，兩個相連，裝在機架3上構成一體，各槽各有跳汰區A、B和隔膜區C，在A、B兩區之間用不到底的隔板分開。各槽共助於同一傳動裝置4，配水活瓣5，如圖二所示，及補助水管6，跳汰區上部跳汰過程靠隔膜往復運動造成水的鼓動來進行礦物分選，隔膜下沖時，在篩板下麵供給補助水，補助水用配水活瓣5來調節，活瓣5與隔膜7的動作是同步的，當隔膜下降時活瓣關閉，水不進入跳汰機中，但隔膜上升時，活瓣啟開因此，減少瞭跳汰機內下降水流的作用。

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 equipped 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.

槽體是灰口鐵鑄造而成，隔膜7乃固定在槽體水平鐵墊8上密封而不漏，隔膜借助於偏心連桿9、10及隔膜連桿11與杠桿12相連接，並由杠桿12獲得往復運動，因而在工作室造成相應的鼓動，杠桿又與套在軸13上的偏心連桿相連接，軸14由電動機15，通過三角皮帶16及皮帶輪17代動。

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階梯形，原礦經給礦槽18送入跳汰室，基於礦物比重不同，被水驅動而分別排出，沉入下層的是比重大的礦物經過截門19膠管20（膠管長度需根據實際使用條件決定）進入排礦瓶21，在上層比重小的礦物沿溢流槽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、安裝與試驗

4.0 Installation and Testing

XCT隔膜式跳汰機安裝在車間平地上或案臺上，若為輔助設備時，或與其它設備相配置時，應考慮到給礦，排礦及檢查修理等工作的方便，跳汰機安裝地點應有220/380伏的電源，補助水壓為0.6-2Kg/㎝².

XCT diaphragm jig is installed on flat ground or table in the workshop. If it is an auxiliary equipment, or used with other equipment, 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.

當跳汰機安裝完成後應以水平機進行水平的檢查不得有歪斜現象，接通電源進行空車試驗不少於2小時，如一切順利則進行負荷試車，負荷試車時應以正常操作規程進行，試車結果合格後，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 equipment can be put into use.

每當機器移動，一定要將機器固緊木板上。

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

五、使用與調整

5.0 Use and Adjustment

隔膜式跳汰機的兩個槽是相等的，而安裝高度不同，以便易於從第一室流入第二室的連續作業，礦物原料由給礦槽送入跳汰室，籍隔膜作往復運動而獲得鼓動水流，礦物借水力作用而移動。因此，隔膜的沖程大小有很大的意義。

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.

沖程和沖次主要決定於被處理物質的粒度被處理物質越粗，則所需沖程愈大，而沖次愈少，調節隔膜沖程大小時，要考慮到所采用的沖程能保證人工床有很好的活動性，當其他條件相同時，厚的人工床或高的尾板需要較大的沖程以便能克服較大的阻力。

  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.

隔膜下沖時人工床在某一時期內，應當成為浮懸狀態，不但不破壞其完整性，當轉為吸入行程時，吸力不應大得使礦粒過分緊密。

  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.

為調節隔膜沖程，松開偏心瓦螺釘，調到所需距離後，再重新緊固，同時應註意兩個隔膜的沖程應相等。如圖三

  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.

所選礦物達到要求或玻璃瓶註滿礦物後，可將截門關閉，將排礦瓶中礦物取出。

  After separated ores meet requirements 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、潤  滑

1、跳汰機的偏心軸承及各主軸軸承均系滑動軸承，每隔連槽工作8小時註濃厚潤滑油一次。

1. Eccentric bearing of the jig and each main bearing are of sliding bearings which shall be applied with thickening lubricating oil once per every 8 working hours of the chute.

2、電動機的軸承每隔6個月更換優質濃厚潤滑油一次。

2. For bearing of the motor, apply with high-quality lubricating oil once per 6 months.
