Description

Technical Field

[0001] The utility model relates to the field of oil tanks, in particular to an easy-to-clean steam turbine oil tank. Background Art

[0002] The oil tank of a steam turbine is a container for storing lubricating oil, which is mainly used to lubricate various parts of the steam turbine. The lubricating oil is pumped to the parts that need lubrication through an oil pump, and then returns to the oil tank after use.

[0003] When the existing turbine oil tank is in use, a filter is installed inside it, so when the refluxed oil enters the oil tank for reuse, it is filtered through the filter to maintain the cleanliness of the oil entering the oil circuit. However, long-term use will cause the filter surface to be clogged, which will affect subsequent use and increase the frequency of manual cleaning intervention.

[0004] In order to solve the above problems, the present application proposes an easy-to-clean steam turbine oil tank. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes an easy-to-clean turbine oil tank. The utility model is provided with a cleaning mechanism so that the oil level inside the box changes continuously and reciprocates in the vertical direction to clean the filter screen, thereby achieving a self-cleaning effect.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides an easy-to-clean steam turbine oil tank, comprising a tank body, wherein a protruding accommodation shell is formed downwardly at the bottom of the tank body;

[0009] A filter screen is fixedly installed inside the box body and the containing shell;

[0010] The filter screen divides the interior of the box into a clean chamber and a dirty chamber, and a cleaning mechanism for cleaning the filter screen and the inner wall of the dirty chamber is placed inside the dirty chamber;

[0011] The cleaning mechanism reciprocates along the height direction of the box body due to the change of the oil inside the box body.

[0012] Preferably, the cleaning mechanism comprises a floating frame and bristles, wherein the floating frame is fixedly connected to one end of the bristles on one side facing the filter screen, and the other end of the bristles is slidably connected to the filter screen.

[0013] Preferably, the top of the floating frame forms an inclined surface toward the inner bottom.

[0014] Preferably, a partition plate is fixedly mounted on the bottom of the filter screen, and the partition plate is fixedly connected to the inner wall of the containing shell.

[0015] Preferably, the bottom of the accommodating shell is connected to a drain valve.

[0016] Preferably, both sides of the top of the box are connected with pipes.

[0017] The above technical solution of the utility model has the following beneficial technical effects:

[0018] The oil is filtered through the filter and reaches the clean chamber of the box to facilitate reuse. As the liquid level inside the box continues to change, it drives the floating frame to move up and down in the vertical direction, driving the bristles to clean the filter and the inner wall of the dirty chamber, thereby reducing the possibility of filter blockage, achieving a self-cleaning effect and reducing the frequency of manual intervention.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] like Figure 1-2 As shown, the utility model provides an easy-to-clean steam turbine oil tank, comprising a tank body 1, wherein a protruding accommodation shell 2 is formed downwardly at the bottom of the tank body 1;

[0024] A filter screen 3 is fixedly installed inside the box body 1 and the containing shell 2;

[0025] The filter screen 3 divides the interior of the box body 1 into a clean chamber and a dirty chamber, and a cleaning mechanism 4 for cleaning the filter screen 3 and the inner wall of the dirty chamber is placed inside the dirty chamber;

[0026] The cleaning mechanism 4 reciprocates along the height direction of the box body 1 due to the change of the oil inside the box body 1.

[0027] In an optional embodiment, there are multiple groups of cleaning mechanisms 4, and the multiple groups of cleaning mechanisms 4 are connected by connecting rods. The cleaning mechanism 4 includes a floating frame 41 and bristles 42. The floating frame 41 is fixedly connected to one end of the bristles 42 facing the side of the filter net 3, and the other end of the bristles 42 is slidably connected to the filter net 3.

[0028] The floating frames 41 are connected by connecting rods. The interior of the floating frames 41 is hollow.

[0029] It should be noted that there are multiple bristles 42 , and the multiple bristles 42 are evenly distributed.

[0030] In an optional embodiment, the top of the floating frame 41 forms an inclined surface toward the inner bottom.
