以下对该多功能组合式油料清理设备的具体工作过程进行说明：The specific working process of this multifunctional combined oil cleaning equipment is described below:
两台振动电机22同方向转动从而带动筛分机壳体20前后往复运动，油料由进料口8通过除铁器7进入筛分机壳体20中，除铁器7四周装有强磁铁能去除油料中能被磁吸的金属杂质，进入筛分机壳体20的油料直接落到振动区上筛网19上。The two vibration motors 22 rotate in the same direction to drive the screening machine housing 20 to reciprocate forward and backward. The oil enters the screening machine housing 20 from the feed port 8 through the iron remover 7. Strong magnets are installed around the iron remover 7 to remove the oil. Metal impurities that can be magnetically attracted, and the oil entering the screening machine housing 20 directly fall onto the screen mesh 19 in the vibration area.
振动区上筛网19装在筛分机壳体20设置的轨道上呈一定倾斜角度，振动区上筛网19里面装有振动球，振动球随筛分机壳体20的运动使振动区上筛网19快速抖动，振动区上筛网19具有较大的孔径，较大的杂质会被留在振动区上筛网19上方随振动区上筛网19的往复运动移动至与振动区上筛网19较高端相连的大杂出口12处，从而排出机体。The upper screen mesh 19 in the vibration area is installed on the track provided by the screening machine housing 20 at a certain inclination angle. The upper screen mesh 19 in the vibration area is equipped with a vibrating ball. The vibration ball moves with the movement of the screening machine housing 20 to cause the upper screen mesh in the vibration area to move upward. The screen 19 shakes rapidly. The screen 19 in the vibration area has a larger aperture. The larger impurities will be left on the screen 19 in the vibration area and move to the upper screen in the vibration area with the reciprocating motion of the screen 19 in the vibration area. The higher end of the net 19 is connected to the large trash outlet 12, thereby being discharged from the body.
通过振动区上筛网19的油料落到与振动区上筛网19平行正对的振动区中间筛网18上，振动区中间筛网18的固定方式与振动区上筛网19相同。振动区中间筛网18具有比振动区上筛网19小一些的孔径，无法通过的中小杂质会通过振动区中间筛网18的往复运动移动到与振动区中间筛网18较高端相连的中小杂出口13处，随后排出机体。The oil passing through the upper screen 19 in the vibration area falls onto the middle screen 18 in the vibration area that is parallel to the upper screen 19 in the vibration area. The middle screen 18 in the vibration area is fixed in the same way as the upper screen 19 in the vibration area. The middle screen mesh 18 in the vibration zone has a smaller aperture than the upper screen mesh 19 in the vibration zone. The small and medium-sized impurities that cannot pass through will move to the small and medium-sized impurities connected to the higher end of the middle screen mesh 18 in the vibration zone through the reciprocating motion of the middle screen mesh 18 in the vibration zone. Exit 13, and then discharged from the body.
通过振动区中间筛网18的油料落在与振动区中间筛网18平行正对的振动区下筛网17上，振动区下筛网17的孔径比干净油料的直径要小，油料在振动区下筛网17的振动下，其中的灰土等杂质会被抖落下来汇集至振动区下筛网17下方的灰杂出口14。The oil that passes through the middle screen 18 of the vibration zone falls on the lower screen 17 of the vibration zone that is parallel to the middle screen 18 of the vibration zone. The aperture of the lower screen 17 of the vibration zone is smaller than the diameter of the clean oil. The oil is in the vibration zone Under the vibration of the lower screen 17, impurities such as dirt and dust will be shaken off and collected into the dust outlet 14 below the lower screen 17 in the vibration zone.
无法通过振动区下筛网17的油料在振动区下筛网17的往复运动下移动至较高端的滑道即区域间通道1d内落入风选区上筛网4上。风选区上筛网4孔径从较高侧向较低侧孔径逐渐减小，由于孔径越小物料向前运动趋势越明显，使物料更容易分散开。The oil that cannot pass through the lower screen 17 in the vibration zone moves to the higher end slideway, that is, the inter-region channel 1d, and falls onto the upper screen 4 in the winnowing zone under the reciprocating motion of the lower screen 17 in the vibration zone. The aperture of screen mesh 4 in the winnowing area gradually decreases from the higher side to the lower side. Since the smaller the aperture, the more obvious the forward movement tendency of the material is, making it easier for the material to disperse.
落到风选区上筛网4上的油料会被溅起分散，分散油料中的灰土、瘪子、杂壳等较轻杂物被风机6从吸风口5吸入到沙克龙9中。沙克龙9中的较大较重杂物会汇集到沙克龙下端排出去，小尘土等较小较轻杂物跟空气从沙克龙9排气口通过通气管道10排入气体收集箱11中。气体收集箱11四周外壳上开有细密排气槽，能挡住灰杂排出干净空气。The oil that falls on the screen 4 in the winnowing area will be splashed and dispersed, and the lighter debris such as dust, flats, and miscellaneous shells in the dispersed oil will be sucked into the shakron 9 from the suction port 5 by the fan 6. Larger and heavier debris in the Shakron 9 will be collected at the lower end of the Shakron and discharged. Smaller and lighter debris such as small dust and air will be discharged from the exhaust port of the Shakron 9 into the gas collection box through the ventilation duct 10. 11 in. There are fine exhaust slots on the surrounding shell of the gas collection box 11, which can block dust and discharge clean air.
通过风选区上筛网4的油料大部分落到拨料板3上，拨料板3为实心板，落在挡料板3上的油料会再次溅起从而充分把油料中的轻杂从吸风口5排出，吸风口5上设置有风量调节板以便调节风量。从拨料板3上经过的物料会落在与风选区上筛网4平行正对的风选区下筛网2上。Most of the oil that passes through the screen 4 in the airflow area falls on the material shifting plate 3. The material shifting plate 3 is a solid plate. The oil falling on the baffle plate 3 will splash again to fully absorb the light impurities in the oil. The air outlet 5 discharges, and the air suction outlet 5 is provided with an air volume adjusting plate to adjust the air volume. The material passing through the material dialing plate 3 will fall on the lower screen 2 of the winnowing area that is parallel to the upper screen 4 of the winnowing area.
风选区下筛网2的孔径比油料小，油料中的较重的石杂、其他种子等重杂会因为比重和筛分机壳体20内气压的不同往风选区下筛网2较高端运动，并从筛分机壳体20下方的重杂出口15处排出，拨料板3会挡住落在此处的油料而使油料不会从重杂出口15排出。而比重杂轻的干净油料沿着风选区下筛网2从其较低端的干净油料出口24排出。The aperture of the lower screen 2 in the airflow area is smaller than that of the oil. The heavier impurities such as stones and other seeds in the oil will move to the higher end of the lower screen 2 in the airflow area due to the difference in specific gravity and air pressure in the screen casing 20. , and be discharged from the heavy miscellaneous outlet 15 below the screen casing 20. The material shifting plate 3 will block the oil falling here so that the oil will not be discharged from the heavy miscellaneous outlet 15. The clean oil that is lighter than heavy impurities is discharged from the clean oil outlet 24 at its lower end along the lower screen 2 of the winnowing area.
该多功能组合式油料清理设备具有筛分、磁选、风选、比重去石等多种筛选功能，其结构紧凑，占地面积小，清理效果好，不产生废气污染，可满足油料加工企业对油料清理的要求。This multifunctional combined oil cleaning equipment has multiple screening functions such as screening, magnetic separation, air separation, and specific gravity stone removal.
