As the usage time increases, the filter surface of the filter cylinder can be switched, that is, the lower end diameter of the filter cylinder is reduced and fits the outer wall of the intake pipe, and the upper end diameter is increased and fits the inner wall of the shell, so that the filter net is turned inside out, so that the inner wall of the filter cylinder faces the flow direction of the gas, that is, the inner wall of the filter cylinder is used as the filter surface to intercept and filter the oil mist in the gas, and the oil mist condenses on the inner wall of the filter cylinder to form oil droplets and flows downward into the inner oil ring groove. By alternately switching the inner and outer walls of the filter cylinder as the filter surface, the possibility of clogging of the filter cylinder can be reduced, thereby reducing the frequency of cleaning the filter cylinder, making it more convenient to use.
进一步地，本发明通过在过滤圆筒的外侧滑动套设弹性束紧环，在内侧顶撑弹性顶撑环，在弹性束紧环和弹性顶撑环沿过滤圆筒的对应侧壁上下滑动过程中，能够对过滤圆筒的内壁和外壁上的油滴和杂质进行刮除，进而防止过滤圆筒被堵塞。Furthermore, the present invention slides an elastic tightening ring on the outer side of the filter cylinder and supports the elastic supporting ring on the inner side. When the elastic tightening ring and the elastic supporting ring slide up and down along the corresponding side walls of the filter cylinder, the oil droplets and impurities on the inner and outer walls of the filter cylinder can be scraped off, thereby preventing the filter cylinder from being blocked.

本发明的一种机加工中心油雾分离装置的一种实施例，如图1至图11所示，该机加工中心油雾分离装置100应用在机加工中心200中，用于连接在机加工中心200的顶部位置。所述机加工中心200的顶部设有安装座210，所述安装座210为环形筒体，所述环形筒体的内部具有与机加工中心200内部连通的排气管，所述排气管与环形筒体同轴设置。所述环形筒体侧壁上设有抽气管212，所述抽气管212用于与抽气泵连接。本发明的机加工中心油雾分离装置安装在安装座210上，所述排气管与机加工中心油雾分离装置100内部连通，工作时，抽气管212向外抽气，使得机加工中心200内带有油雾的气体从排气管进入机加工中心油雾分离装置100内部，气体中的油雾被机加工中心油雾分离装置100拦截过滤，过滤后的气体从抽气管212排出。An embodiment of an oil mist separation device for a machining center of the present invention is shown in FIGS. 1 to 11 . The oil mist separation device 100 for a machining center is applied to a machining center 200 and is used to be connected to the top of the machining center 200. A mounting seat 210 is provided on the top of the machining center 200. The mounting seat 210 is an annular cylinder. The interior of the annular cylinder has an exhaust pipe connected to the interior of the machining center 200. The exhaust pipe is coaxially arranged with the annular cylinder. An exhaust pipe 212 is provided on the side wall of the annular cylinder. The exhaust pipe 212 is used to be connected to an exhaust pump. The oil mist separation device for a machining center of the present invention is installed on a mounting seat 210, and the exhaust pipe is connected to the interior of the oil mist separation device 100 of the machining center. During operation, the exhaust pipe 212 draws air outward, so that the gas containing oil mist in the machining center 200 enters the interior of the oil mist separation device 100 of the machining center from the exhaust pipe, and the oil mist in the gas is intercepted and filtered by the oil mist separation device 100 of the machining center, and the filtered gas is discharged from the exhaust pipe 212.
本发明中，该机加工中心油雾分离装置100包括外壳110和位于外壳110内的过滤网，所述外壳110为上端封闭下端开口的圆柱筒体，所述外壳110的轴线沿上下方向延伸，所述外壳110的下端用于与机加工中心200的安装座210固定连接。所述外壳110内同轴设置有进气管道111，所述进气管道111的下端用于与机加工中心200的排气管上端对接，使得进气管道111与排气管连通。所述外壳110的内壁与所述进气管道111的外壁之间形成环形过滤腔，所述进气管道111的上端与所述环形过滤腔连通，所述外壳110的下端为出气端。工作时，排气管中的气体从进气管道111的下端进入，并从进气管道111的上端进入环形过滤腔中，然后沿环形过滤腔向下流动，然后从外壳110的下端排出至抽气管212。In the present invention, the oil mist separation device 100 for a machining center includes a housing 110 and a filter screen located in the housing 110. The housing 110 is a cylindrical body with a closed upper end and an open lower end. The axis of the housing 110 extends in the up-down direction. The lower end of the housing 110 is used to be fixedly connected to the mounting seat 210 of the machining center 200. An air intake pipe 111 is coaxially arranged in the housing 110. The lower end of the air intake pipe 111 is used to dock with the upper end of the exhaust pipe of the machining center 200, so that the air intake pipe 111 is connected to the exhaust pipe. An annular filter chamber is formed between the inner wall of the housing 110 and the outer wall of the air intake pipe 111. The upper end of the air intake pipe 111 is connected to the annular filter chamber, and the lower end of the housing 110 is an air outlet. During operation, the gas in the exhaust pipe enters from the lower end of the air intake pipe 111 and enters the annular filter chamber from the upper end of the air intake pipe 111 , then flows downward along the annular filter chamber, and then is discharged from the lower end of the shell 110 to the exhaust pipe 212 .
本发明中，所述过滤网为由一张金属网卷曲而成的过滤圆筒120，所述过滤圆筒120位于环形过滤腔中并与所述进气管道111同轴设置。初始状态下，所述过滤圆筒120为上端直径小下端直径大的圆锥筒，如图6所示状态，此时，所述过滤圆筒120的上端与进气管道111的外壁贴合，下端与外壳110的内壁贴合，使过滤圆筒120的外壁面朝气体的流动方向，也即过滤圆筒120的外壁为过滤面，气体中的油雾在过滤圆筒120的外壁上汇聚成油滴。本发明中，过滤圆筒120由一张金属网卷曲多圈形成，使过滤圆筒120的侧壁具有多层金属网。所述过滤圆筒120的金属网的内端和外端分别可以沿金属网的周向上移动，使得过滤圆筒120的上端直径能够增大并与外壳110的内壁贴合，下端直径能够减小并与进气管道111的外壁贴合，以使过滤圆筒120的内壁面朝气体流动方向。In the present invention, the filter net is a filter cylinder 120 formed by curling a metal net, and the filter cylinder 120 is located in the annular filter chamber and is coaxially arranged with the air intake pipe 111. In the initial state, the filter cylinder 120 is a conical cylinder with a small diameter at the upper end and a large diameter at the lower end, as shown in FIG6. At this time, the upper end of the filter cylinder 120 is in contact with the outer wall of the air intake pipe 111, and the lower end is in contact with the inner wall of the housing 110, so that the outer wall of the filter cylinder 120 faces the flow direction of the gas, that is, the outer wall of the filter cylinder 120 is the filtering surface, and the oil mist in the gas gathers into oil droplets on the outer wall of the filter cylinder 120. In the present invention, the filter cylinder 120 is formed by curling a metal net for multiple turns, so that the side wall of the filter cylinder 120 has multiple layers of metal nets. The inner end and the outer end of the metal mesh of the filter cylinder 120 can move along the circumference of the metal mesh respectively, so that the upper end diameter of the filter cylinder 120 can be increased and fit with the inner wall of the shell 110, and the lower end diameter can be reduced and fit with the outer wall of the air intake pipe 111, so that the inner wall of the filter cylinder 120 faces the gas flow direction.
本实施例中，所述过滤圆筒120外滑动套设有用于向内束紧过滤圆筒120的弹性束紧环130，所述过滤圆筒120内滑动设有用于向外顶撑过滤圆筒120的弹性顶撑环160。所述弹性束紧环130连接有驱动机构，所述驱动机构用于驱动所述弹性束紧环130沿过滤圆筒120的外壁向下滑动。所述驱动机构包括转动安装在外壳110内壁上的丝杠116，所述丝杠116的轴线沿上下方向延伸，所述丝杠116的上端连接有用于驱动所述丝杠116旋转的电机117，所述丝杠116与弹性束紧环130之间设有第一导向伸缩臂140，所述第一导向伸缩臂140的一端设有螺纹孔143，所述丝杠116穿装在螺纹孔143中，所述螺纹孔143与丝杠116螺纹配合，使得所述丝杠116转动能够带动第一导向伸缩臂140上下移动。所述第一导向伸缩臂140的另一端与弹性束紧环130连接，以带动弹性束紧环130沿过滤圆筒120的外壁上下移动。In this embodiment, an elastic tightening ring 130 for tightening the filter cylinder 120 inwardly is slidably sleeved outside the filter cylinder 120, and an elastic supporting ring 160 for supporting the filter cylinder 120 outwardly is slidably sleeved inside the filter cylinder 120. The elastic tightening ring 130 is connected to a driving mechanism, and the driving mechanism is used to drive the elastic tightening ring 130 to slide downward along the outer wall of the filter cylinder 120. The driving mechanism includes a lead screw 116 rotatably mounted on the inner wall of the housing 110, the axis of the lead screw 116 extending in the up-down direction, the upper end of the lead screw 116 is connected to a motor 117 for driving the lead screw 116 to rotate, a first guide telescopic arm 140 is provided between the lead screw 116 and the elastic tightening ring 130, one end of the first guide telescopic arm 140 is provided with a threaded hole 143, the lead screw 116 is inserted into the threaded hole 143, the threaded hole 143 is threadedly matched with the lead screw 116, so that the rotation of the lead screw 116 can drive the first guide telescopic arm 140 to move up and down. The other end of the first guide telescopic arm 140 is connected to the elastic tightening ring 130 to drive the elastic tightening ring 130 to move up and down along the outer wall of the filter cylinder 120.
初始状态下，所述弹性束紧环130位于所述过滤圆筒120的上端，并使过滤圆筒120的上端与进气管道111的外壁贴合，所述弹性顶撑环160位于过滤圆筒120的下端，并使过滤圆筒120的下端与进气管道111的内壁贴合；当需要切换过滤圆筒120的过滤面时，启动驱动机构，使其带动第一导向伸缩臂140向下移动，进而带动过滤圆筒120向下滑动。由于过滤圆筒120是由金属网卷曲而成，因此自身具有向外扩张的弹力，在弹性束紧环130向下移动后，过滤圆筒120上端的束紧力被解除，在过滤圆筒120自身弹力的作用下上端直径会增大，而下端会受到弹性束紧环130的束紧力，进而直径会减小。这样随着弹性束紧环130逐渐下移，过滤圆筒120的上端直径逐渐增大，下端的直径逐渐减小。所述弹性顶撑环160在过滤圆筒120的上端直径大于下端直径时，由于弹性顶撑环160具有向上的顶撑作用力，使得弹性顶撑环160能够顺着过滤圆筒120的内壁自动向上滑动至过滤圆筒120的上端，并对过滤圆筒120的上端内壁进行顶撑。当弹性束紧环130滑动至过滤圆筒120的下端时，过滤圆筒120的下端被束紧在进气管道111的外壁上，所述弹性顶撑环160向外顶撑过滤圆筒120的上端使其紧贴在外壳110的内壁上，此时过滤圆筒120为上端直径大、下端直径小的倒圆锥筒，使得过滤圆筒120的内壁面朝气体的流动方向，即过滤圆筒120的内壁成为过滤面，油雾在过滤圆筒120的内壁上形成油滴。In the initial state, the elastic tightening ring 130 is located at the upper end of the filter cylinder 120, and makes the upper end of the filter cylinder 120 fit with the outer wall of the air intake pipe 111, and the elastic top support ring 160 is located at the lower end of the filter cylinder 120, and makes the lower end of the filter cylinder 120 fit with the inner wall of the air intake pipe 111; when it is necessary to switch the filter surface of the filter cylinder 120, the driving mechanism is started to drive the first guide telescopic arm 140 to move downward, thereby driving the filter cylinder 120 to slide downward. Since the filter cylinder 120 is formed by curling the metal mesh, it has its own elastic force to expand outward. After the elastic tightening ring 130 moves downward, the tightening force at the upper end of the filter cylinder 120 is released. Under the action of the elastic force of the filter cylinder 120 itself, the diameter of the upper end will increase, while the lower end will be tightened by the elastic tightening ring 130, thereby reducing the diameter. In this way, as the elastic tightening ring 130 gradually moves downward, the diameter of the upper end of the filter cylinder 120 gradually increases, and the diameter of the lower end gradually decreases. When the diameter of the upper end of the filter cylinder 120 is larger than the diameter of the lower end, the elastic supporting ring 160 has an upward supporting force, so that the elastic supporting ring 160 can automatically slide upward along the inner wall of the filter cylinder 120 to the upper end of the filter cylinder 120 and support the inner wall of the upper end of the filter cylinder 120. When the elastic tightening ring 130 slides to the lower end of the filter cylinder 120, the lower end of the filter cylinder 120 is tightened on the outer wall of the air intake pipe 111, and the elastic supporting ring 160 supports the upper end of the filter cylinder 120 outward to make it close to the inner wall of the outer shell 110. At this time, the filter cylinder 120 is an inverted cone with a large diameter at the upper end and a small diameter at the lower end, so that the inner wall of the filter cylinder 120 faces the flow direction of the gas, that is, the inner wall of the filter cylinder 120 becomes a filtering surface, and the oil mist forms oil droplets on the inner wall of the filter cylinder 120.
所述外壳110的下端分别设有外接油环槽115和内接油环槽114，所述外接油环槽115位于外壳110内壁的内侧，用于在过滤圆筒120的下端与外壳110内壁贴合时接收油液，所述内接油环槽114位于进气管道111外壁的外侧，用于在过滤圆筒120的下端与进气管道111外壁贴合时接收油液。The lower end of the outer shell 110 is respectively provided with an external oil ring groove 115 and an internal oil ring groove 114. The external oil ring groove 115 is located on the inner side of the inner wall of the outer shell 110, and is used to receive oil when the lower end of the filter cylinder 120 is in contact with the inner wall of the outer shell 110. The internal oil ring groove 114 is located on the outer side of the outer wall of the intake pipe 111, and is used to receive oil when the lower end of the filter cylinder 120 is in contact with the outer wall of the intake pipe 111.

初始状态下，过滤圆筒120的上端与进气管道111的外壁贴合，下端与外壳110的内壁贴合，过滤圆筒120呈上端小、下端大的锥形筒，此时过滤圆筒120的外壁为过滤面，油液在过滤圆筒120的外壁形成，并流入下方的外接油环槽115中。当过滤圆筒120使用一定时间后，抽气泵停止抽气，并启动电机117来驱动丝杠116开始旋转，进而带动第一导向伸缩臂140和弹性束紧环130向下移动，弹性束紧环130向下移动的过程中，过滤圆筒120的上端由于失去束缚力会开始向外扩张，而过滤圆筒120的下端由于弹性束紧环130的束紧力而开始向内收缩。在第一导向伸缩臂140向下移动到过滤圆筒120的中间位置后，再继续向下移动时，会使过滤圆筒120形成上端大、下端小的漏斗状，此时弹性顶撑环160会因为向外扩张的力而向过滤圆筒120的上端移动，使得过滤圆筒120的上端与外壳110的内壁贴合，当弹性束紧环130移动到过滤圆筒120的下端后，即完成过滤圆筒120的内外翻转。翻转后的过滤圆筒120的内壁成为新的过滤面，并且形成的油液会流入内接油环槽114中。并且翻转后的过滤圆筒120再次工作时，会受到气体的反吹作用，使得原本停留在过滤圆筒120外壁上的杂质会被气体带走。In the initial state, the upper end of the filter cylinder 120 is in contact with the outer wall of the air intake pipe 111, and the lower end is in contact with the inner wall of the housing 110. The filter cylinder 120 is a tapered cylinder with a small upper end and a large lower end. At this time, the outer wall of the filter cylinder 120 is a filtering surface, and oil is formed on the outer wall of the filter cylinder 120 and flows into the outer oil ring groove 115 below. After the filter cylinder 120 has been used for a certain period of time, the air pump stops pumping air, and the motor 117 is started to drive the lead screw 116 to start rotating, thereby driving the first guide telescopic arm 140 and the elastic tightening ring 130 to move downward. During the downward movement of the elastic tightening ring 130, the upper end of the filter cylinder 120 will begin to expand outward due to the loss of restraining force, while the lower end of the filter cylinder 120 will begin to shrink inward due to the tightening force of the elastic tightening ring 130. After the first guide telescopic arm 140 moves downward to the middle position of the filter cylinder 120, it continues to move downward, making the filter cylinder 120 form a funnel shape with a large upper end and a small lower end. At this time, the elastic top support ring 160 will move toward the upper end of the filter cylinder 120 due to the outward expansion force, so that the upper end of the filter cylinder 120 fits the inner wall of the shell 110. When the elastic tightening ring 130 moves to the lower end of the filter cylinder 120, the filter cylinder 120 is turned inside out. The inner wall of the flipped filter cylinder 120 becomes a new filtering surface, and the formed oil will flow into the inner oil ring groove 114. And when the flipped filter cylinder 120 works again, it will be backblown by the gas, so that the impurities originally staying on the outer wall of the filter cylinder 120 will be taken away by the gas.
当再次工作一段时间后，启动电机117反向转动，使弹性束紧环130向上移动，位于上方的弹性顶撑环160会再次回到下方，使过滤圆筒120恢复到初始状态，即实现过滤圆筒120的又一次翻转。在弹性束紧环130和弹性顶撑环160上下移动时，会对过滤圆筒120的内外表面进行刮除，有助于过滤圆筒120的清洁。After working for a period of time again, the motor 117 is started to rotate in the reverse direction, so that the elastic tightening ring 130 moves upward, and the elastic supporting ring 160 located above returns to the bottom again, so that the filter cylinder 120 returns to the initial state, that is, the filter cylinder 120 is flipped again. When the elastic tightening ring 130 and the elastic supporting ring 160 move up and down, the inner and outer surfaces of the filter cylinder 120 are scraped, which helps to clean the filter cylinder 120.
