[0009] 本发明的目的是如此来实现的。 [0009] The object of the present invention is thus achieved.

[0010] 卧螺离心机与液压站的一体式配置结构,在矩形机架中,一侧为横卧配置的卧螺离心机筒体,另一侧的端部配置电动机,经皮带传送给离心机筒体的输入轴端,其特征在于:在电动机的后部空间内配置液压站, [0010] The unitary arrangement Decanters hydraulic station, in a rectangular rack, one side lying Decanters cylindrical configuration, the end portion of the motor is disposed on the other side, the belt conveyor to the centrifuge machine input shaft barrel, wherein: hydraulic station arranged in the rear space of the motor,

[0011] 所述液压站为竖立配置的矩形体,油泵电机驱动油泵,油泵经两个进油调速阀分别由前、后两根进油管连接至离心机筒体的两端,供油箱和回油箱并列配置在下部,且两油箱的下部相互连通,供油箱的上部连接真空泵。 [0011] The hydraulic station is arranged upright rectangular body, the motor driven oil pump, the oil pump are connected by front and rear ends to the two intake pipe via two centrifuge cylinder into the oil control valve for the fuel tank, and return tank are arranged in parallel in a lower portion, and the lower two tank communicate with each other, is connected to a vacuum pump for the upper reservoir. [0012] 进一步,所述供油箱和回油箱是由隔板垂直将油箱隔成供油箱和回油箱两个腔体,且隔板与底板间隔一定高度形成连通部。 [0012] Further, the oil supply tank and back to the tank by a vertical partition plate for the fuel tank and the fuel tank separated into two chambers back to the tank, the separator and the bottom plate portion spaced a predetermined height is formed in communication.

[0013] 进一步,所述供油箱和回油箱之间连通部的高度占油箱总高度的0. 1-0. 3。 [0013] Further, the oil supply tank and the height of the back portion of the communication between the reservoir tank to the total height of 0. 1-0. 3.

[0014] 进一步,在所述进油管和回油管路中连接压力表。 [0014] Further, a pressure gauge connected to the inlet pipe and the return line.

[0015] 进一步,在所述进油管的管路中分别连接一油过滤器。 [0015] Further, the inlet pipe line are connected to an oil filter.

[0016] 现有技术卧螺离心机的配置结构,其布局经过长期使用考验结构相对固定,比较紧凑,运行平稳,不便做较大的改动,否则,不仅成本将会有较大上升,而且会对其它部件的工作稳定性、可靠性带来问题,因此本发明尽量在现有技术基础上对离心机、液压站进行设计和布局。 [0016] arrangement of the prior art decanter centrifuge, its layout after long-term use of the test structure is relatively fixed, relatively compact, smooth running, inconvenience make major changes. Otherwise, not only will have a larger increase in costs, but also other components of the operating stability, reliability cause problems, the present invention is thus possible to design and layout of the centrifuge, the hydraulic station on the basis of the prior art. 但是在改造中突出的问题为:①现有技术两根进油管分别由两个油泵供油,比较容易控制油路,及两端的压力,而本发明为了将液压站配置在离心机的机架上,为了结构紧凑,降低成本使用的是单泵结构。 However, in the projection transformation problems as follows: ① two prior art oil inlet respectively, by two oil pump, oil easier to control, and the pressure at both ends, but the present invention is to centrifuge the hydraulic station arranged at the frame , in order compact, lower cost using a single pump structure. 液压站是配置在机架的电动机后部空间内,相对于离心机是偏离中心位置的,因此管路相对离心机是非对称布置,单泵的出油口难以位于离心机两端轴承座的中间位置,管路长度的不同势必造成两路供油量不均,一路供油太多,而另一路太少,影响稀油的均勻分配,这两种情况都不利于稀油润滑轴承的稳定运行;②由于受安装空间的限止,考虑装置的稳定性,也为了美观,液压站下部油箱体积尽可能小,尽可能低,但为了回油通畅又必须使回油箱上方的空间增大,高度增高,此间存在矛盾。 The hydraulic station is disposed in the rear of the rack space motor is off-center with respect to the position of the centrifuge, the centrifuge is asymmetric relative to the line thus arranged, the single pump oil outlet port located intermediate the ends difficult chock centrifuge a different location, the length of the pipeline will inevitably result in two unequal amount of oil, all the way too much oil, and the other way too, affect uniform distribution of light oil, both of which are not conducive to the stable operation of thin oil-lubricated bearings ; ② limiting, due to the installation space, considering the stability of the device, but also for aesthetic purposes, a lower hydraulic oil tank small as possible, as low as possible, but in order to open the oil return must turn back to the tank above the space is increased, increasing the height , there is a contradiction here.

[0017] 在本发明的技术方案中,采用了进油调速阀元件,它是根据前后两侧进油压力来控制阀门的开启和关闭,使得离心机前后两端的油压达到相互平稳的程度。 [0017] In the aspect of the present invention, using the oil inlet control valve member, which is based on the front and rear sides into the oil pressure to control valve opening and closing, so that the oil pressure reaches the front and rear ends of each smooth centrifuge degree . 因此,即使液压站相对于离心机是偏离中心配置的,离心机两端管路长度不同,但是通过本技术方案,仍能保证两端的压力一致。 Thus, even if the hydraulic station is off-center with respect to the configuration of the centrifuge, the centrifuge ends of different length tubing, but the present technical solution, the pressure can still be consistent across.

[0018] 其次,本发明的油箱采用了供油箱和回油箱两个分油箱,并列配置在装置的下部, 且两油箱的下部相互连通,在供油箱的上部连接真空泵。 [0018] Next, the present invention employs a tank for the fuel tank and the fuel tank to tank two points, arranged in parallel in a lower portion of the apparatus, and the lower two tank communicate with each other, a vacuum pump connected to the upper portion of the oil supply tank. 液压站下部油筒采用双箱结构设计,用板将油箱隔成供油箱和回油箱两个腔体,而底部有一定间隙,使两个腔体连通,在供油箱的上部连接真空泵。 A lower oil hydraulic cylinder with double box design, with a plate for the fuel tank and the fuel tank separated into two chambers back to the tank, and there is a gap at the bottom, communicating the two cavities, a vacuum pump connected to an upper portion of the supply tank. 这种结构的设计能够增加轴承座回油口与液压站回油口之间油位高度差,使回油顺畅,其工作原理是:当油箱内装油后,油量大约为油缸体积的1/2-3/4,然后将供油箱上部由真空泵抽成负压状态,而回油箱是与大气连通的,两腔体内油面存在压力差,形成高度差,供油箱油位H高于回油箱油位h,油位高度差AH = Hh。 Design of such a structure capable of increasing the bearing housing hydraulic oil return port and the oil level difference between the return port, so that a smooth oil return, its working principle is: when the in-tank oil, cylinder oil volume is approximately 1 / 2-3 / 4, and then evacuated by a vacuum pump for the upper reservoir into a negative pressure state, and back to the tank is in communication with the atmosphere, there are two differential pressure oil chamber, a height difference is formed, the oil supply tank to tank is higher than the level H oil level h, the oil level difference AH = Hh. 当液压站工作时,供油箱内的油被泵不断抽出,送入轴承座,H降低,由于上部空间为负压,借助回油箱上部大气压的作用,回油箱内的油不断压入供油箱,使H回到原来位置,同时ΔΗ不发生变化, 如此循环,就能够维持h在较低位置,使得回油管的出口有较大的落差,保持系统的畅通循环和运行。 When the hydraulic working oil supply tank is pumped out continuously, into the bearing seat, H decreases, since the upper space of the negative pressure, the atmospheric pressure by means of upper reservoir back to the role of oil in the tank back into the supply tank for the continuous press, H back to the original position, while ΔΗ does not change, so the cycle, h can be maintained at a lower position so that the outlet of the return pipe has a larger gap, smooth circulation and keep the system running. 为保证双缸结构的有效运行,增加小型真空泵,并采用逻辑控制,以保持供油箱上部腔体稳定负压,同时依靠调节负压大小,来控制回油箱油位高度。 To ensure the effective operation of the cylinder structure, increase minipump, and the use of control logic, for holding the tank to the upper chamber stable negative pressure, while relying on the size of the negative pressure regulator to control the oil back to the tank height.

[0019] 本发明的优点和优越性:本技术方案的液压站安装在卧螺离心机机架上,液压站与轴承座用油管连接,形成稀油循环回路。 [0019] Advantages and advantages of the present invention: This aspect of a hydraulic station mounted on the frame Decanters, and bearing with hydraulic tubing connector, form a dilute oil circuit. 这种设计充分利用了机架上剩余的空间,节省现场空间,同时省去了分体式结构中运输与安装麻烦的问题,加快工程进度,提高效率。 This design takes advantage of space left on the rack, saving space scene, while eliminating the problem of split structure in the transportation and installation problems, speed up the progress of the project and improve efficiency.

[0020] 单泵双路双缸液压站与卧螺离心机一体式结构,可以提高工程效率,降低成本。 [0020] The single pump station with dual duplex hydraulic Decanters unitary structure, can improve the process efficiency and reduce costs. 采用了进油调速阀元件,它是根据前后两侧进油压力来控制阀门的开启和关闭,使得离心机前后两端的油压达到相互平稳的程度。 Using the oil into the control valve element, which is based on front and rear sides into the oil pressure to control the opening and closing of the valve, so that the oil pressure reaches the front and rear ends of each centrifuge steady level. 而在供油箱上方设置真空泵,巧妙地利用了负压原理,供油箱和回油箱的下方相互连通,保证回油箱有较大的落差,保证回油的顺畅,又降低了油箱的整体高度,解决了一体式设计带来的问题,为稀油润滑轴承的稳定运行创造了良好的条件。 In the top of the tank for vacuum pump set, clever use of the principle of negative pressure, and back to the bottom of the tank for tank communicate with each other to ensure a greater drop back to the tank, to ensure the smooth return of oil, but also reduces the overall height of the tank, the solution problems caused by the one-piece design, and create favorable conditions for the stable operation of the oil lubrication of the bearing.
