Description

Technical Field

[0001] This utility model relates to the field of filter cloth perforation, and more specifically to a filter cloth perforation device for plate and frame filter presses. Background Technology

[0002] The filter cloth in a plate and frame filter press is the core filtration medium, directly affecting filtration efficiency, filter cake moisture content, equipment operating costs, and filter cloth lifespan. It typically has five through holes for filtrate flow; therefore, perforation is required during filter cloth processing. However, due to the thin and lightweight nature of the filter cloth, existing perforation devices often fail to keep the cloth flat on the perforation platform, thus affecting the perforation quality. Utility Model Content

[0003] This utility model provides a filter cloth punching device for plate and frame filter presses, which makes it easier to keep the filter cloth flat and lay it on the punching platform plate, thereby affecting the punching quality.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A filter cloth perforation device for a plate and frame filter press includes a platform plate with multiple cut holes, a support plate extending forward from the front end of the platform plate, a baffle plate at the rear end of the platform plate, vertical columns fixed at both ends of the platform plate, a gantry frame fixed at the upper end of the two vertical columns, a cutting mechanism sliding on the two vertical sliding rods, two sliding rods sliding through the gantry frame, a horizontal pressure plate fixed at the lower end of the two sliding rods, and a spring I between the two sliding rods and the gantry frame to press the horizontal pressure plate against the support plate.

[0006] The upper surface of the tray is lower than the upper surface of the platform plate.

[0007] The lower rear end of the horizontal pressure plate is provided with a rounded corner.

[0008] The front end of the platform plate has rounded corners.

[0009] The tray is tilted forward and extends downward with an extension plate.

[0010] The hole-cutting mechanism includes a lifting frame that slides through two vertical columns, and the lower end face of the lifting frame is provided with multiple cutting columns corresponding to the cutting holes.

[0011] Each cut column has a through hole at its center.

[0012] A power telescopic rod is provided between the lifting frame and the gantry frame.

[0013] Two light columns slide through the lifting frame. A pressure plate is fixed at the lower end of the two light columns. A spring II is provided between the pressure plate and the lifting frame. The pressure plate is provided with multiple through holes corresponding to the cutting columns.

[0014] The platform plate is equipped with support legs at all four corners.

[0015] The beneficial effects of this utility model are as follows: Initially, one side of the square filter cloth material is pulled tight so that the side passes between the horizontal pressure plate and the support plate, passes through the platform plate and then presses against the baffle. At this time, the other end of the square filter cloth is clamped by the horizontal pressure plate and the support plate, so that the square filter cloth material is kept flat and laid flat on the platform plate. At this time, the hole-cutting mechanism is controlled to descend to complete the hole cutting, ensuring the hole-cutting quality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is combined with Figure 1-6 A detailed description of a filter cloth perforation device for a plate and frame filter press is provided:

[0026] A filter cloth perforation device for a plate and frame filter press includes a platform plate 1 with multiple cut holes 2, a support plate 3 extending forward from the front end of the platform plate 1, a baffle 4 at the rear end of the platform plate 1, vertical columns 5 welded and fixed to both the left and right ends of the platform plate 1, a portal frame 6 welded and fixed to the upper end of the two vertical columns 5, a cutting mechanism sliding on the two vertical sliding rods 5, two sliding rods 9 sliding through the portal frame 6, a horizontal pressure plate 8 welded and fixed to the lower end of the two sliding rods 9, and a spring Ⅰ10 provided between the two sliding rods 9 and the portal frame 6 to press the horizontal pressure plate 8 against the support plate 3.

[0027] During punching, take a square filter cloth material and pull one side tight so that the side passes between the horizontal pressure plate 8 and the support plate 3, passes through the platform plate 1 and is pressed against the baffle 4. At this time, the other end of the square filter cloth is pressed against the support plate 3 by the horizontal pressure plate 8 under the elastic force of the spring I10, forming a clamp. At this time, the square filter cloth material is kept flat on the platform plate 1. Then, control the hole cutting mechanism to descend and complete the hole cutting, thereby achieving the purpose of keeping the filter cloth flat on the punching platform plate, which in turn affects the punching quality.

[0028] Further:

[0029] Since the upper surface of the support plate 3 is lower than the upper surface of the platform plate 1, the filter cloth needs to be bent upwards after passing through the horizontal pressure plate 8 and the support plate 3 before it can slide onto the platform plate 1. This allows the horizontal pressure plate 8 and the support plate 3 to better clamp the filter cloth, thereby maintaining the flatness of the filter cloth.

[0030] Further:

[0031] The filter cloth is provided with rounded corners at the lower rear end of the horizontal pressure plate 8 and at the front end of the platform plate 1. This facilitates the filter cloth to slide upwards after passing the horizontal pressure plate 8 and backwards at the rear end of the platform plate 1. The rounded corners also prevent the filter cloth from being scratched.

[0032] Further:

[0033] The tray 3 is tilted forward and extends downward with an extension plate.

[0034] By setting the extension plate, an opening is made at the front end of the support plate 3 and the horizontal pressure plate 8, which makes it easier for the filter cloth to enter between the support plate 3 and the horizontal pressure plate 8 through the opening.

[0035] Further:

[0036] The hole-cutting mechanism includes a lifting frame 11 that slides through two vertical columns 5, and the lower end face of the lifting frame 11 is provided with a plurality of cutting columns 12 corresponding to the cutting holes 2.

[0037] Each cut post 12 has a through hole at its center.

[0038] A power telescopic rod 7 is provided between the lifting frame 11 and the gantry frame 6.

[0039] The power telescopic rod 7 can be a hydraulic cylinder or an electric telescopic rod. By controlling the extension of the power telescopic rod 7, the lifting frame 11 is pushed down, so that multiple cutting columns 12 are inserted into multiple cutting holes 2 respectively, forming a punching-type cutting and punching of the filter cloth between the two.

[0040] The cutting post 12 has a through hole in its center, which allows air to pass through when the cutting post 12 is inserted into the cutting hole 2.

[0041] Further:

[0042] Two light columns 14 slide through the lifting frame 11. A pressure plate 13 is welded and fixed to the lower end of the two light columns 14. A spring II 15 is provided between the pressure plate 13 and the lifting frame 11. The pressure plate 13 is provided with multiple through holes corresponding to the cutting column 12.

[0043] The upper ends of the two light columns 14 are provided with retaining rings, which are used to press the upper end of the lifting frame 11 downward when the spring II 15 presses the pressure plate 13 downward, thereby limiting the pressure plate 13 and ensuring that the pressure plate 13 can move up and down with the lifting frame 11.

[0044] During the punching process, as the lifting frame 11 descends, the pressure plate 13 first contacts the filter cloth and, through the elastic force of the spring II 15, presses the filter cloth firmly against the upper surface of the platform plate 1. Then, as the lifting frame 11 continues to descend, the cutting column 12 passes through the pressure plate 13 to complete the cutting and punching. Thus, the filter cloth is clamped by the pressure plate 13 and the platform plate 1, preventing the filter cloth from being stretched and deformed or moved during punching, which would affect the quality.

[0045] Further:

[0046] The platform plate 1 is provided with support legs at all four corners to support the platform plate 1.

[0047] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
