Description

Technical Field

[0001] This utility model relates to the field of filter support frames, and more particularly to a filter media support frame. Background Technology

[0002] Box filters are a common type of filtration equipment widely used in water treatment, air purification, and liquid filtration. Their main function is to remove impurities or particulate matter from fluids, ensuring fluid cleanliness.

[0003] Existing technologies, such as the utility model patent with publication number CN220899788U, disclose a box-type filter. This patent employs a mounting plate and a filter tank with an inlet pipe and an outlet pipe fixed to the top of the mounting plate. A first housing and a second housing are located outside the filter tank and on the mounting plate. The second housing is situated between the first housing and the filter tank, forming an accommodating space between the spaced-apart first and second housings. A first support rod and a second support rod are arranged inside this accommodating space, with the second support rod positioned between two adjacent first support rods. A third support rod is arranged perpendicular to the first support rods on the side of the second housing opposite to the first housing, with the filter tank situated between the third support rods. The sides of the first and second support rods are connected to the first and second housings, respectively. This utility model box-type filter significantly improves the overall structural strength, preventing the filter tank from bursting and causing debris to fly everywhere, thus enhancing overall safety performance.

[0004] In daily use, it has been found that if the filter screen does not have sufficient support, it will deform or even break during use, affecting the filtration effect. Moreover, the deformation of the filter screen will cause unevenness of the filtration surface, thereby reducing the filtration area, resulting in reduced filtration efficiency, and even causing particulate matter to pass through the filter screen into the filtered fluid. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a filter media support frame.

[0006] To solve the above technical problems, this utility model provides a filter media support frame, including: a box body and an installation structure. A filter screen is disposed inside the box body, and the filter screen is connected to the box body via the installation structure. The installation structure includes a bracket, which is fixedly connected to the box body. The filter screen is distributed inside the bracket. Two connecting rails are fixedly connected to the upper surface of the bracket. A sliding rod is slidably connected to the inner wall of the connecting rail. A stop block is fixedly connected to the lower end of the sliding rod, and the stop block is in contact with the filter screen. A round rod is slidably connected to the inner wall of the sliding rod. A connecting block is fixedly connected to the upper end of the round rod. A spring is fitted onto the arc surface of the round rod, and both ends of the spring are fixedly connected to the connecting block and the sliding rod, respectively. Two insertion rods are fixedly connected to the lower surface of the connecting block. Several insertion holes are opened on the upper surface of the connecting rail, and the insertion rods are adapted to the insertion holes. A connecting rod is fixedly connected to one side of the two connecting blocks that are close to each other.

[0007] The effect achieved by the above components is as follows: when it is necessary to attach the filter screen to the bracket, pull the connecting block to move it. The connecting block drives the round rod to slide on the inner wall of the slide rod. The connecting block drives the spring to stretch. The connecting block drives the insertion rod to separate from the insertion hole. Then pull the slide rod to move it. The slide rod drives the abutment block to move. Then the abutment block drives the filter screen to attach to the bracket. After moving to the appropriate position, align the insertion rod with the insertion hole. Then release the connecting block spring to drive the connecting block to reset. The connecting block drives the insertion rod to insert into the insertion hole for fixation.

[0008] Preferably, a protective pad, which is a rubber pad, is fixedly connected to the side of the abutment block near the support.

[0009] The effect achieved by the above components is that the protective pad can protect the filter screen and prevent the abutment from abrading the filter screen when it comes into contact with it.

[0010] Preferably, a limiting rod is fixedly connected to the inner wall of the connecting rail, and the limiting rod is slidably connected to the slide rod.

[0011] The effect achieved by the above components is that the limiting rod can limit the sliding rod, prevent the sliding rod from deviating during sliding, and improve the stability of the sliding rod.

[0012] Preferably, the cross-section of the round rod is circular, and the round rod is a stainless steel rod.

[0013] The effect achieved by the above components is that the round rod can limit the spring, prevent the round rod from deforming during use, and improve the service life of the spring.

[0014] Preferably, the bracket has several auxiliary structures inside, each auxiliary structure including a fixing plate, which is fixedly connected to the bracket. A screw is slidably connected to the inner wall of the fixing plate, and a threaded ring is threadedly connected to the arc surface of the screw. The threaded ring is rotatably connected to the fixing plate, and a connecting pad is fixedly connected to the end of the screw away from the threaded ring.

[0015] The effect achieved by the above components is as follows: when it is necessary to fix both ends of the filter screen, the connecting pad is pulled to move, the connecting pad drives the screw to move, then the screw is inserted into the filter screen and the fixing plate, then the threaded ring is rotated to move, the threaded ring drives the screw to move, the screw drives the connecting pad to move, and then the connecting pad drives the filter screen and the fixing plate to fit and fix.

[0016] Preferably, an auxiliary pad is fixedly connected to the side of the connecting pad near the screw, and the auxiliary pad has a circular cross-section.

[0017] The effect achieved by the above components is that the protective pads can protect the filter screen and prevent wear when fixing the two ends of the filter screen.

[0018] Preferably, the arc surface of the threaded ring is provided with a plurality of slots, and the plurality of slots are evenly distributed on the threaded ring.

[0019] The effect achieved by the above components is that the groove can increase the friction between the threaded ring and the hand, preventing slippage when rotating the threaded ring.

[0020] Compared with related technologies, the filter media support frame provided by this utility model has the following beneficial effects:

[0021] By setting up an installation structure, the existing technology allows the filter screen to deform or even break during use if it does not have sufficient support, affecting the filtration effect. Moreover, filter screen deformation can lead to uneven filtration surface, thereby reducing the filtration area and reducing filtration efficiency. It can even allow particulate matter to pass through the filter screen and enter the filtered fluid. This device achieves the effect of conveniently and reasonably supporting the filter screen, easily and quickly attaching the filter screen to the bracket, and quickly installing, disassembling and replacing the filter screen and bracket for cleaning.

[0022] By incorporating an auxiliary structure, the two ends of the filter screen can be easily secured, preventing the screen from falling off or warping during use. Attached Figure Description
