Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and specifically relates to a combined V-shaped filter. Background Art

[0002] The combined V-shaped filter is usually used for filtering liquids or gases and is common in industrial production. It is usually composed of two V-shaped filters combined together, which can provide a larger filtration area and higher filtration efficiency. This design can reduce the replacement frequency of the filter, extend the service life, and has a larger filtration area and better filtration effect under the same size. At the same time, the combined V-shaped filter usually has a lower pressure drop and has less impact on the system.

[0003] For example, a combined high-efficiency V-shaped filter proposed in the patent with the publication number CN214861891U uses the provided support plate for installation and fixation. When the device needs to be moved and transported, first, slide the first T-shaped slider towards the middle to gather the movable bars inside the first support plate. The angle of the frame also changes as the movable bars move. Then, the outer walls of each frame are closely attached. Next, pull the second support plate towards both ends to separate the insertion rod from the inner wall of the card slot, and then rotate the second support plate downward by 90° to complete the folding. The shielding cover is a plastic film made of polytetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing performance, high lubricity and non-stickiness, electrical insulation, and good anti-aging endurance. It can not only play a sealing role but also change its shape and shrink when the device is folded. The folded second support plate will swing. The design of the first magnetic block and the second magnetic block can play a role in firmly connecting to achieve the effect of convenient transportation.

[0004] When the above device is in use, the first T-shaped slider is used to drive the movable bars to move closer to the inside of the first support plate, so that the frames are mutually attached, and the first support plate is rotated to complete the folding. However, when the first T-shaped slider moves, it first needs to contact the restriction between the spring port and the first support plate, and the operation is relatively troublesome. At the same time, the position of the first T-shaped slider after movement is not fixed, and it may become loose during the movement process. Summary of the Utility Model

[0005] To solve the problems raised in the above background art, the utility model provides a combined V-shaped filter. Through the mutual cooperation between the contraction structure and the limiting structure, the position of the connecting frame after movement can be fixed, preventing loosening during subsequent transportation. At the same time, the operation steps are simple and easy to understand, facilitating the operation of the staff, thereby solving the problems of relatively troublesome operation and loosening during the movement process.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A combined V-shaped filter, comprising a filter device body, a contraction structure and a limit structure are respectively installed inside and on the outer surface of the filter device body. The contraction structure includes a rotating block, a rotating rod, a connecting ring and a contraction rope. The bottom of the rotating block is fixedly connected to the top of the rotating rod, and the outer surface of the rotating rod is fixedly connected to the inner wall of the connecting ring. A circular groove adapted to the contraction rope is provided on the outer surface of the connecting ring, and one end of the contraction rope is fixedly connected to the inside of the connecting ring.

[0007] Preferably, the filter device body includes a connecting plate, a first rotating plate, a second rotating plate, a connecting frame and a V-shaped filter net. The bottom of the rotating block is in contact with the top of the connecting plate, and one end of the rotating rod passes through the inner wall of the connecting plate.

[0008] Preferably, the bottom of the first rotating plate is hinged to the bottom of the connecting plate, and the top of the first rotating plate is fixedly connected to the connecting plate by bolts.

[0009] Preferably, a sliding groove is provided inside the connecting plate. The outer surface of the connecting frame is slidably connected to the inner wall of the sliding groove, and the outer surface of the connecting ring is located inside the sliding groove. The outer surface of the V-shaped filter net is clamped to the inner wall of the connecting frame, and the connecting frames are connected to each other by filter nets. A compression spring is fixedly installed on the inner wall of the connecting frame. The outer surface of the contraction rope is located inside the compression spring, and the other end of the contraction rope extends into the connecting frame.

[0010] Preferably, the limit structure includes a pressing plate, a rotating column, a connecting block, a movable plate, a movable spring and a fixing plate. The outer surface of the rotating column is fixedly connected to the inner wall of the pressing plate, and the other end of the rotating column is rotatably connected to the inside of the connecting plate.

[0011] Preferably, the top of the movable plate is rotatably connected to the inside of the pressing plate. The connecting block is located on one side of the movable plate and is fixedly connected to the bottom of the pressing plate. The bottom of the movable plate is located inside the rotating block.

[0012] Preferably, one end of the movable spring is fixedly connected to the edge of the bottom of the pressing plate, and the other end of the movable spring is fixedly connected to the top of the fixing plate. The side surface of the fixing plate is fixedly connected to the outer surface of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The utility model is provided with a compression spring, a retractable rope, a rotating block and a movable plate. By means of the rotating block, the rotating rod and the connecting ring are driven to rotate, and the rotation of the connecting ring forces the retractable rope to continuously wind around the outer surface of the rotating rod. As the retractable rope continuously contracts, the compression spring will be continuously squeezed under the drive of the connecting frame, so that the connecting frame smoothly enters the inside of the connecting plate from the inside of the first rotating plate and the second rotating plate under the cooperation of the retractable rope and the chute. The rotating block can only rotate in a specified direction under the limitation of the movable plate and the connecting block, effectively preventing the rotating block from loosening, thus facilitating the staff to fold the first rotating plate and the second rotating plate, and making the folded filter device body convenient for subsequent transportation.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 6 shown, the utility model provides a combined V-shaped filter, which includes a filter device body 1. A contraction structure 2 and a limit structure 3 are respectively installed inside and on the outer surface of the filter device body 1. The contraction structure 2 includes a rotating block 21, a rotating rod 22, a connecting ring 23 and a contraction rope 24. The bottom of the rotating block 21 is fixedly connected to the top of the rotating rod 22, and the outer surface of the rotating rod 22 is fixedly connected to the inner wall of the connecting ring 23. A circular groove adapted to the contraction rope 24 is provided on the outer surface of the connecting ring 23, and one end of the contraction rope 24 is fixedly connected to the inside of the connecting ring 23.

[0024] Adopting the above scheme: Through the setting of the rotating block 21, the rotating block 21 can be used to drive the rotating rod 22 and the connecting ring 23 to rotate, so that the rotated connecting ring 23 can wind the contraction rope 24 around the outer surface of the rotating rod 22, and through the winding of the contraction rope 24, the connecting frame 14 can be continuously moved towards the connecting plate 11 under the drive of the compression spring 141 and enter the inside of the connecting plate 11.

[0025] As Figures 4 to 5 shown, the filter device body 1 includes a connecting plate 11, a first rotating plate 12, a second rotating plate 13, a connecting frame 14 and a V-shaped filter net 15. The bottom of the rotating block 21 is in contact with the top of the connecting plate 11, and one end of the rotating rod 22 penetrates the inner wall of the connecting plate 11. The bottom of the first rotating plate 12 is hinged to the bottom of the connecting plate 11, and the top of the first rotating plate 12 is fixedly connected to the connecting plate 11 by bolts. A chute is provided inside the connecting plate 11. The outer surface of the connecting frame 14 is slidably connected to the inner wall of the chute, and the outer surface of the connecting ring 23 is located inside the chute. The outer surface of the V-shaped filter net 15 is snap-connected to the inner wall of the connecting frame 14, and the connecting frames 14 are connected to each other by a filter net. A compression spring 141 is fixedly installed inside the connecting frame 14. The outer surface of the contraction rope 24 is located inside the compression spring 141, and the other end of the contraction rope 24 extends into the inside of the connecting frame 14.

[0026] Adopting the above scheme: Through the setting of the connecting frame 14, the position of the V-shaped filter net 15 can be fixed, and at the same time, the V-shaped filter net 15 can be driven to move. Through the setting of the compression spring 141, the connecting frames 14 can be continuously squeezed in cooperation with the contraction rope 24, which is convenient for better entering the inside of the connecting plate 11. At the same time, when the pressure brought by the contraction rope 24 is lost, the positions of the connecting frame 14 and the V-shaped filter net 15 can be restored to their original positions. Through the setting of the first rotating plate 12 and the second rotating plate 13, the whole device can be folded, thus facilitating subsequent transportation.

[0027] As Figure 2 andFigure 6 As shown, the limiting structure 3 includes a pressing plate 31, a rotating column 32, a connecting block 33, a movable plate 34, a movable spring 35 and a fixed plate 36. The outer surface of the rotating column 32 is fixedly connected to the inner wall of the pressing plate 31, and the other end of the rotating column 32 is rotatably connected to the inside of the connecting plate 11, the top of the movable plate 34 is rotatably connected to the inside of the pressing plate 31, and the connecting block 33 is located on one side of the movable plate 34 and fixedly connected to the bottom of the pressing plate 31, the bottom of the movable plate 34 is located inside the rotating block 21, one end of the movable spring 35 is fixedly connected to the edge of the bottom of the pressing plate 31, and the other end of the movable spring 35 is fixedly connected to the top of the fixed plate 36, and the side of the fixed plate 36 is fixedly connected to the outer surface of the connecting plate 11.

[0028] The above solution is adopted: by setting the movable plate 34 and the connecting block 33, the rotating block 21 can only rotate in the specified direction during the rotation process, effectively preventing the rotating block 21 from loosening itself under the inertia of the compression spring 141. By setting the pressing plate 31 and the movable spring 35, the end of the pressing plate 31 without the movable spring 35 is pressed downward, so that the other end of the pressing plate 31 is driven by the movable spring 35 and the rotating column 32 to tilt upward as a whole, so that the tilted pressing plate 31 drives the connecting block 33 and the movable plate 34 to disengage from the interior of the rotating block 21, so that the rotating block 21 can rotate in the opposite direction.

[0029] The working principle and usage process of the present invention are as follows: First, the staff rotates the rotating block 21, and drives the rotating rod 22 and the connecting ring 23 to move synchronously. As the connecting ring 23 rotates, the contraction rope 24 is continuously wrapped around the outer surface of the rotating rod 22. At this time, the connecting frames 14 are continuously approached to each other under the drive of the contraction rope 24, and the compression spring 141 is squeezed, so that the V-shaped filter screens 15 are folded with each other and smoothly enter the interior of the connecting plate 11.

[0030] Then, loosen the bolts to release the fixation between the first rotating plate 12 and the second rotating plate 13 and the connecting plate 11, and at the same time use the hinge to flip the first rotating plate 12 and the second rotating plate 13 toward the bottom of the V-shaped filter screen 15, so that the flipped first rotating plate 12 and the second rotating plate 13 are in contact with each other, thereby facilitating subsequent transportation. When the device needs to be unfolded as a whole, one end of the pressing plate 31 is pressed downward, so that the other end of the pressing plate 31 continues to tilt upward under the drive of the rotating column 32 and the movable spring 35, and drives the movable plate 34 and the connecting block 33 to disengage from the interior of the rotating block 21. Using the same principle, the connecting frame 14, the V-shaped filter screen 15, the first rotating plate 12 and the second rotating plate 13 are restored to their original positions. At this point, the overall operation process is completed.
