Of course, they are only examples, and the purpose is not to limit the utility model.

[0049] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0050] Example 1

[0051] Please refer to Figures 1-3 , Figures 5-7 , Figure 13 and Figure 14 , the embodiment discloses a filter device for pure steam generator, including fixed frame 1, fixed frame 1 needs to be installed in pure steam generator for filtering parts such as pipe 2, the installation mode is to set the socket 20 in the side wall surface of pipe 2, so that fixed frame 1 can be inserted into the inside of pipe 2 through socket 20, and the outer wall surface of fixed frame 1 is tightly combined with the inner wall surface of pipe 2, prevent waste water from flowing through the gap between fixed frame 1 and pipe 2, resulting in the decrease of waste water filtration effect. First sliding slot 14 is set on the opposite inner wall surface in fixed frame 1 respectively, connecting plate 3 is arranged in first sliding slot 14, so that the two ends of connecting plate 3 are slidably connected with fixed frame 1 through first sliding slot 14 respectively, filter screen 30 is arranged on the outer bottom of connecting plate 3, filter screen 30 and the inner wall surface of fixed frame 1 are tightly combined, prevent waste water from flowing through the gap between filter screen 30 and fixed frame 1, resulting in the decrease of waste water filtration effect.

[0052] A cavity 12 is formed in the side wall of the fixed frame 1, a first through hole 10 is formed in the outer top of the fixed frame 1 and communicates with the cavity 12, and a second through hole 11 is formed in the outer wall of the fixed frame 1 and communicates with the cavity 12. The second through hole 11 is two, one is located on the end face of the fixed frame 1 facing the direction of the wastewater flow, and the other is located on the end face of the fixed frame 1 facing the direction opposite to the wastewater flow. A limiting assembly 4 is arranged in the cavity 12, and the limiting assembly 4 can limit the fixed frame 1 in the pipeline 2. Specifically, the limiting assembly 4 includes a rotating rod 40, two connecting rods 41 and two limiting rods 42. One end of the rotating rod 40 is rotatably connected between the cavity 12 and the fixed frame 1, and the other end extends to the outer top of the fixed frame 1 through the first through hole 10. The two connecting rods 41 are respectively hinged to the outer wall of the rotating rod 40, and the limiting rods 42 are respectively hinged to the other ends of the two connecting rods 41. The limiting rods 42 are arranged in the second through hole 11, so that the limiting rods 42 are slidably connected between the second through hole 11 and the fixed frame 1. It should be noted that after the fixed frame 1 is inserted into the pipeline 2 through the socket 20, a fixed hole 23 corresponding to the second through hole 11 is formed in the closed surface of the pipeline 2 compared with the fixed frame 1. When the fixed frame 1 needs to be limited and fixed, the rotating rod 40 is rotated, the connecting rod 41 located on the outer wall is moved after the rotating rod 40 is rotated, the limiting rod 42 at the other end is moved when the connecting rod 41 moves, the limiting rod 42 moves in the second through hole 11 to enter the fixed hole 23, so that the limiting of the fixed frame 1 in the pipeline 2 is completed, and the pipeline 2 is prevented from falling out of the socket 20.

[0053] In the limiting process of the limiting assembly 4, in order to enhance the limiting effect of the limiting assembly 4, the number of the limiting assembly 4 can be increased to two groups, and the two groups of limiting assemblies 4 are respectively located on the two sides of the fixed frame 1, so as to improve the limiting effect of the fixed frame 1. In addition, when the limiting rod 42 is partially located in the fixed hole 23 to form a limit, in order to prevent the rotating rod 40 from rotating due to external influence and causing the limiting rod 42 to move back to be entirely located in the second through hole 11 and unable to limit the fixed frame 1, a limiting block 43 is hinged to the outer top of the rotating rod 40, and a clamping groove 16 is formed in the top of the fixed frame 1, as shown in Figure 13 and Figure 14 When the rotating rod 40 is rotated to the position that the limiting rod 42 is located in the fixed hole 23 and the limiting of the fixed frame 1 is completed, the limiting block 43 is rotated to cooperate with the clamping groove 16 in the top of the fixed frame 1 at this time, so as to prevent the rotating rod 40 from rotating back due to external influence and affecting the limiting of the fixed frame 1.

[0054] The adjusting hole 13 is arranged on the top of the fixed frame 1, the lifting assembly 5 is arranged in the adjusting hole 13, the lifting assembly 5 is arranged on the outer top of the connecting plate 3, the connecting plate 3 can slide in the first sliding groove 14 through the lifting assembly 5, so that the lifting effect of the connecting plate 3 is achieved, specifically, the lifting assembly 5 comprises a first adjusting rod 50, one end of the first adjusting rod 50 is connected with the outer top of the connecting plate 3, the other end of the first adjusting rod 50 extends to the outside of the fixed frame 1 through the adjusting hole 13, when the scale attached to the filter screen 30 on the outer bottom of the connecting plate 3 is more, the user can hold the first adjusting rod 50 outside the top of the fixed frame 1 and lift it, the first adjusting rod 50 drives the connecting plate 3 and the filter screen 30 to lift, after the filter screen 30 is lifted, the gap between the bottom of the filter screen 30 and the inner bottom of the fixed frame 1 is formed, then the user releases the first adjusting rod 50, the connecting plate 3 and the filter screen 30 fall under the action of gravity, until the connecting plate 3 cannot continue to slide and fall in the first sliding groove 14, at this time, the connecting plate 3 collides with the fixed frame 1, so that the scale attached to the filter screen 30 falls due to vibration, so that the cleaning effect of the scale attached to the surface of the filter screen 30 is achieved.

[0055] Example 2

[0056] This embodiment is a further optimization based on example one, specifically, please refer to Figure 4 、 Figures 8-12As shown, the lifting assembly 5 further comprises a second adjusting rod 51, a fixed seat 53 and an adjusting block 52. In this embodiment, the second adjusting rod 51 is rotatably connected with the adjusting hole 13, and has a gap between the outer top of the connecting plate 3, which allows the connecting plate 3 to move upward. The fixed seat 53 is arranged on the outer top of the connecting plate 3, and a curved surface 530 is arranged on the end face of the fixed seat 53 facing the second adjusting rod 51, which can be matched with the outer wall surface of the second adjusting rod 51. An adjusting groove 531 is formed on the curved surface 530 of the fixed seat 53 and spirally distributed along the central axis of the second adjusting rod 51, and the adjusting block 52 is arranged in the adjusting groove 531, so that the adjusting block 52 can slide on the curved surface 530 of the fixed seat 53 through the adjusting groove 531. The adjusting block 52 is arranged on the outer wall surface of the second adjusting rod 51. It should be noted that the adjusting block 52 intermittently contacts the adjusting groove 531 when sliding in the adjusting groove 531, that is, the adjusting block 52 does not slide in the adjusting groove 531 all the time when the second adjusting rod 51 rotates. When the adjusting block 52 enters the adjusting groove 531, the entrance position of the adjusting groove 531 is higher than the exit position of the adjusting groove 531 when the adjusting block 52 slides out of the adjusting groove 531. When it is necessary to vibrate and clean the scale attached to the filter screen 30, the user holds the second adjusting rod 51 outside the top of the fixed frame 1 and rotates it. At this time, the connecting plate 3 is in a stationary state, the filter screen 30 at the outer bottom of the connecting plate 3 is tightly attached to the inner wall surface of the fixed frame 1, and the adjusting block 52 is not in the adjusting groove 531. After the second adjusting rod 51 starts to rotate, the adjusting block 52 rotates circumferentially around the central axis of the second adjusting rod 51 until the adjusting block 52 enters the adjusting groove 531. At this time, the adjusting block 52 rotates circumferentially in the horizontal plane, while the adjusting groove 531 is spirally distributed along the central axis of the second adjusting rod 51, so that the adjusting block 52 can slide in the adjusting groove 531, and the adjusting block 52 can push the fixed seat 53 upward to drive the connecting plate 3 at the bottom of the fixed seat 53 to move upward until the adjusting block 52 is about to slide out of the adjusting groove 531. At this moment, the bottom of the filter screen 30 is away from the inner bottom of the fixed frame 1. After the adjusting block 52 slides out of the adjusting groove 531, the fixed seat 53 loses the support of the adjusting block 52, so that the connecting plate 3, the filter screen 30 and the fixed seat 53 fall under the action of their own gravity until the connecting plate 3 collides with the fixed frame 1. At this time, the scale attached to the filter screen 30 can fall off due to vibration. If the adjusting block 52 continues to rotate with the second adjusting rod 51, the adjusting block 52 can enter the adjusting groove 531 again from the entrance of the adjusting groove 531, and the above process is repeated. The connecting plate 3 is lifted by the fixed seat 53 and then falls off, so that the connecting plate 3 can repeatedly collide with the fixed frame 1, achieving the effect of multiple vibration cleaning of the scale.In addition, in order to facilitate the user to rotate the second adjusting rod 51, the handle 54 can be hinged on the outer top of the second adjusting rod 51 and offset from the central axis of the second adjusting rod 51, so as to achieve the effect of saving labor.

[0057] Wherein, the bottom of the fixed frame 1 is provided with a residue discharging port 15, and after the fixed frame 1 is inserted into the pipeline 2 through the socket 20, the sidewall of the pipeline 2 corresponding to the residue discharging port 15 of the fixed frame 1 is provided with a communication port 22, and the outer wall surface of the pipeline 2 is provided with a collecting box 7 in communication with the communication port 22, and after the scale attached to the filter screen 30 is cleaned by vibration, the scale will fall into the residue discharging port 15 of the fixed frame 1 and then be discharged into the collecting box 7 through the communication port 22 in communication with the residue discharging port 15.

[0058] In the above embodiment, when the scale is shaken and falls off, since there is no closing component such as a valve at the residue discharging port 15, the scale will gradually sink into the collecting box 7 through the residue discharging port 15 and the communication port 22 for precipitation, and the waste water will also be accumulated in the collecting box 7, so that the waste water cannot be recycled, therefore, a valve (not shown in the figure) is arranged at the communication port 22, and when the waste water flows from the pipeline 2, the valve is closed, so that the collecting box 7 cannot be in communication with the waste water in the pipeline 2 through the communication port 22 and the residue discharging port 15, and after the surface of the filter screen 30 is cleaned for many times, the scale will be precipitated on the surface of the valve, when the precipitated scale needs to be cleaned, the waste water is stopped from being discharged, when there is no waste water flowing in the pipeline 2, the valve is opened, so that the precipitated scale enters into the collecting box 7 for collection, and then the valve is closed to continue filtering the waste water.

[0059] Wherein, the outer wall surface of the connecting plate 3 is provided with a sealing gasket (not shown in the figure), and the inside of the adjusting hole 13 is provided with a sealing ring (not shown in the figure), since the fixed frame 1 needs to be inserted into the pipeline 2 through the socket 20 of the pipeline 2 for filtering treatment, in order to avoid the waste water overflowing from the socket 20, the sealing treatment needs to be performed on each closing surface, not only the sealing gasket is arranged on the outer wall surface of the connecting plate 3, but also the sealing gasket is arranged on the closing surface of the fixed frame 1 and the pipeline 2, so as to prevent the waste water from overflowing. In addition, in order to facilitate the user to take out the fixed frame 1 from the pipeline 2, the handle 6 is arranged on the outer top of the fixed frame 1 to facilitate the user to take out the fixed frame 1.

[0060] Finally, it should be noted that: the above is only the preferred embodiment of the present application and is not used to limit the present application, for those skilled in the art, the present application can have various changes and variations, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other at will. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
