技术领域 technical field
本发明涉及过滤装置，具体是指一种初级过滤器。 The invention relates to a filtering device, in particular to a primary filter.
背景技术 Background technique
目前滤油机广泛用于对液压油、液力传动油、齿轮油、汽油机油、柴油机油、压缩机油、冷冻机油以及热处理油等的净化处理，滤油机能够快速脱除油中的水分、气体和机械杂质，闪蒸除掉轻质酸、轻质烃等，进而提高油的品质，回复润滑油的使用性能，保证动力系统、液压系统、润滑系统的正常运行。而现有技术中的通过式过滤器的滤芯组件基本包括两部分，即滤架和滤网，通过熔锡焊接成为滤芯组件，该滤芯组件的过滤精度为80目，当高压液体通过时，介质含有微小金属粒子会通过滤网进入液压系统，对液压阀及千斤顶造成污染，降低阀与千斤顶的使用寿命，甚至会因液压阀的密封失效而出现错误动作，造成人身和设备事故。 At present, the oil filter is widely used in the purification of hydraulic oil, hydraulic transmission oil, gear oil, gasoline engine oil, diesel engine oil, compressor oil, refrigeration oil and heat treatment oil, etc. The oil filter can quickly remove the moisture in the oil , gas and mechanical impurities, flash evaporation to remove light acids, light hydrocarbons, etc., thereby improving the quality of the oil, restoring the performance of the lubricating oil, and ensuring the normal operation of the power system, hydraulic system, and lubrication system. The filter element assembly of the pass-through filter in the prior art basically includes two parts, namely the filter frame and the filter screen, which are welded by melting tin to form the filter element assembly. The filtration accuracy of the filter element assembly is 80 mesh. When the high-pressure liquid passes through, the medium Containing tiny metal particles will enter the hydraulic system through the filter screen, causing pollution to the hydraulic valve and jack, reducing the service life of the valve and jack, and even malfunctioning due to the sealing failure of the hydraulic valve, causing personal and equipment accidents.
并且传统的针对工业用油的初级过滤，通常采用的普通的过滤器以对工业用油中的大直径杂质颗粒等进行处理，但是在工业用油注入过程中，高速的水流对过滤器造成较大的冲击，并且随之高速流动的杂质颗粒对过滤器内各零部件会形成严重的磨损，大大降低了过滤器的使用寿命，现有技术中采用的解决手段为直接通过阀门进行调节工业用油的注入速率，但机械阀门需要人工不断地手动调节，加重了工作人员的劳动负荷，使得工业用油的过滤效率大大降低。 And the traditional primary filtration for industrial oil usually uses ordinary filters to deal with large-diameter impurity particles in industrial oil, but during the injection process of industrial oil, the high-speed water flow has a greater impact on the filter. Large impact, and the impurity particles flowing at high speed will cause serious wear to the parts in the filter, which greatly reduces the service life of the filter. The solution adopted in the prior art is to directly adjust the industrial filter through the valve. The injection rate of the oil is reduced, but the mechanical valve needs to be manually adjusted continuously, which increases the labor load of the staff and greatly reduces the filtration efficiency of industrial oil.
发明内容 Contents of the invention
本发明的目的在于提供一种初级过滤器，自动调节通过过滤器的工业用油流量，降低对过滤器内部的冲击磨损，进而达到保护过滤器的目的。 The purpose of the present invention is to provide a primary filter, which can automatically adjust the flow of industrial oil passing through the filter, reduce the impact and wear on the inside of the filter, and then achieve the purpose of protecting the filter.
本发明的目的通过下述技术方案实现： The object of the present invention is achieved through the following technical solutions:
一种初级过滤器，包括筒体以及开设在筒体上下两端的入油口和出油口，在所述筒体内安装有隔离板，所述隔离板的两端开有多个泄流孔，还包括固定在筒体内的支撑底座，支撑底座内滑动设置有活动杆，在支撑底座的下端设有凹槽，活动杆的下端通过弹簧与凹槽底部连接，活动杆的上端贯穿隔离板且在其端部固定有挡块，所述挡块正对入油口，所述挡块包括圆台形的本体，在所述本体顶端转动设置有滚珠，且在所述本体的外壁上环形设置有多个沿筒体轴线方向的导流槽，在活动杆的中部固定有挡板，当弹簧位于初始位置时，挡板的位置被配置为，挡板的上端面将多个泄流孔遮挡。本发明工作时，工业用油从入油口处进入到筒体内部，直接作用打到挡块上，当工业用油流量增大且流速加快时，作用到挡块上的应力增加，即挡块通过活动杆将应力传送至弹簧上，弹簧受力被压缩，此时位于活动杆上的挡板随活动杆下移，进而使得挡板与隔离板发生脱离，注入筒体内部的工业用油直接从隔离板上的多个泄流孔中流出，工业用油流量越大，流速越快时，弹簧被压缩的程度越高，即通过泄流孔流出的油量就越大，进而实现大流量油液的从出油口中排出；当工业用油流量减小且流速减缓时，弹簧受到的作用应力减小，弹簧回复一定的形变后将活动杆向上弹出，直至停止注入油液时，挡板与隔离板重新接触，进而阻止油液继续从泄流孔中注入；通过活动杆的上下调节来实现油液在筒体内的流量控制，进而减小油液对筒体的冲击，达到保护过滤器的目的； A primary filter, comprising a cylinder body and oil inlets and oil outlets provided at the upper and lower ends of the cylinder body, a separation plate is installed in the cylinder body, and a plurality of discharge holes are opened at both ends of the separation plate, It also includes a support base fixed in the barrel, a movable rod is slidably arranged in the support base, a groove is provided at the lower end of the support base, the lower end of the movable rod is connected with the bottom of the groove through a spring, and the upper end of the movable rod penetrates the isolation plate and is in the Its end is fixed with a block, the block is facing the oil inlet, the block includes a frustum-shaped body, a ball is rotated on the top of the body, and there are multiple rings on the outer wall of the body. A diversion groove along the cylinder axis direction, a baffle plate is fixed in the middle of the movable rod, when the spring is in the initial position, the position of the baffle plate is configured such that the upper end surface of the baffle plate covers a plurality of discharge holes. When the present invention works, the industrial oil enters the inside of the barrel from the oil inlet, and directly acts on the stopper. When the flow rate of the industrial oil increases and the flow speed increases, the stress acting on the stopper increases, that is, the stopper The block transmits the stress to the spring through the movable rod, and the spring is compressed under the force. At this time, the baffle on the movable rod moves down with the movable rod, so that the baffle and the isolation plate are separated, and the industrial oil injected into the cylinder Directly flow out from multiple discharge holes on the isolation plate, the greater the flow of industrial oil and the faster the flow rate, the higher the degree of compression of the spring, that is, the greater the amount of oil flowing out through the discharge holes, thereby achieving large The flow of oil is discharged from the oil outlet; when the flow rate of industrial oil decreases and the flow rate slows down, the acting stress on the spring decreases, and the spring returns to a certain deformation to pop up the movable rod until it stops injecting oil. The plate is in contact with the isolation plate again, thereby preventing the oil from continuing to be injected from the discharge hole; the flow control of the oil in the cylinder is realized by adjusting the movable rod up and down, thereby reducing the impact of the oil on the cylinder and achieving protection and filtration the purpose of the device;
其中，挡块包括圆台形的本体以及转动设置在本体顶部的滚珠，当高速流动的油液注入筒体内部，活动杆受力下移之前，油液直接作用到滚珠上方，由于油液的流动速率的不稳定，因此滚珠会在油液的冲击下开始自由转动，而转动时绝大部分的油液的流动方向发生改变，由垂直流动方向变为水平方向的抛物线运动，在筒体内壁的反弹下进入到泄流孔中，而少部分未发生运动方向改变的油液则沿弧形的导流槽下滑至泄流孔中，通过挡块对油液的分级处理，大大降低了油液高速流动时对活动杆的冲击，使得活动杆在调节油液通过量的过程中更加灵活，同时保护矩形凹槽内的弹簧不会出现骤然受力或是失力的现象，减小弹簧的金属疲劳程度，提高装置的使用寿命。 Among them, the stopper includes a frustum-shaped body and a ball that is rotated on the top of the body. When the high-speed flowing oil is injected into the cylinder, the oil directly acts on the ball before the movable rod is forced to move down. Due to the flow of oil The speed is unstable, so the ball will start to rotate freely under the impact of the oil, and the flow direction of most of the oil will change during the rotation, from the vertical flow direction to the horizontal parabolic movement. It rebounds and enters the discharge hole, while a small part of the oil that has not changed its direction of movement slides down the arc-shaped diversion groove into the discharge hole, and the oil is classified by the stopper, which greatly reduces the oil The impact on the movable rod during high-speed flow makes the movable rod more flexible in the process of adjusting the flow of oil, and at the same time protects the spring in the rectangular groove from sudden force or loss of force, reducing the metal of the spring Fatigue degree, improve the service life of the device.
