Description

Technical Field

[0001] This utility model relates to the field of deep bed filtration devices, and in particular to a filter media filling structure for a deep bed filtration device. Background Technology

[0002] Deep bed filtration systems are devices that achieve high-efficiency filtration through multiple layers of filter media. They are widely used in gas purification, liquid filtration, and wastewater treatment. Their core principle is to utilize the depth of the filter media and the gaps between particles to extend the residence time of pollutants in the filter bed, thereby improving removal efficiency.

[0003] However, traditional deep-bed filtration devices often use a flat top plate laid on top of the filter media, which easily leads to localized material accumulation and uneven loading of the filter media layer. Some areas of the filter media become clogged prematurely, while other areas do not have sufficient contact with the material, reducing the overall retention efficiency.

[0004] Therefore, this utility model proposes a filter media filling structure for a deep bed filtration device. Utility Model Content

[0005] This invention provides a filter media filling structure for a deep bed filtration device, which can solve the problem in the prior art where a flat top plate is laid on top of the filter media, causing the material to easily accumulate in local areas and resulting in uneven load on the filter media layer.

[0006] A deep bed filtration device with a filter media filling structure, comprising: The filling component includes a base plate and a top plate; a connecting cover one is fixedly installed at the upper end of the base plate, and a connecting cover two is fixedly installed at the lower end of the top plate; the connecting cover two covers the outside of the connecting cover one and is connected by a connecting component. Both the base plate and the top plate are pyramidal in shape, and both have multiple through slots.

[0007] Preferably, all the through slots are elongated, and the direction of their long axis is parallel to the inclination direction of the inclined surface of the pyramid.

[0008] Preferably, the top plate has multiple transition grooves at its upper end; the multiple transition grooves are connected to the multiple through grooves one by one; the cross-section of the transition grooves is arc-shaped.

[0009] Preferably, the filler is provided in multiple sets; the multiple sets of filler are stacked in layers.

[0010] Preferably, a fixing bracket is fixedly provided on the upper end of the connecting cover 2.

[0011] Preferably, the mounting bracket has an opening.

[0012] Preferably, the connectors are arranged in multiple sets in a ring array around the filler.

[0013] Preferably, the side wall of the connecting cover 2 is provided with a slot 1; the side wall of the connecting cover 1 is provided with a slot 2; the plug-in includes a plug plate; the plug plate is inserted into the slot 1 and the slot 2.

[0014] Preferably, a handle is fixedly provided on the side wall of the insert plate.

[0015] Preferably, the side wall of the connecting cover is provided with a rotating plate; the rotating plate is provided with a slot; the rotating plate and the slot are engaged and locked together.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: (1) The deep bed filtration device uses a filter media filling structure. Both the bottom plate and the top plate are pyramidal, and multiple through slots are opened on each plate. The multiple through slots are all elongated, and the long axis is parallel to the inclination direction of the inclined surface of the pyramid. As the material flows along the inclined surface of the bottom and top plate pyramids and seeps down into the through slots, the inclined surface can guide the material to flow in multiple directions, so that the material can penetrate evenly into the filter media layer and avoid uneven filtration caused by local concentration. The combination of the bottom plate, top plate and through slots increases the contact area between the material and the filter media, ensuring that each part of the filter media can fully play its interception role, thereby improving the overall filtration efficiency.

[0017] (2) The deep bed filtration device uses a filter media filling structure, including a bottom plate and a top plate; a connecting cover one is fixedly installed at the upper end of the bottom plate, and a connecting cover two is fixedly installed at the lower end of the top plate; the connecting cover two covers the outside of the connecting cover one and is connected by a plug-in connector. The filling components adopt a split design, which can be quickly disassembled and installed. The staff can directly open the top plate and the connecting cover two to visually check the filter media caking and perform local cleaning or replacement of the blocked areas, which greatly simplifies the filter media filling, replacement and equipment maintenance process.

[0018] (3) The deep bed filter device uses a filter media filling structure. The side wall of the connecting cover 2 is provided with slot 1; the side wall of the connecting cover 1 is provided with slot 2; the plug-in component includes a plug plate; the plug plate is inserted into slot 1 and slot 2. By inserting the plug plate into slot 1 and slot 2 in sequence and rotating the rotating plate, the rotating plate is embedded in the bayonet, which can limit the plug plate, thereby fixing the connecting cover 1 and connecting cover 2 together, so as to facilitate the movement and handling of the filling component.

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] like Figure 1-3 As shown in the figure, the filter media filling structure for a deep bed filtration device provided by this utility model embodiment includes a filler 1 and a connector 2. The filler 1 includes a bottom plate 11 and a top plate 13; a connecting cover 12 is fixedly provided at the upper end of the bottom plate 11, and a connecting cover 2 14 is fixedly provided at the lower end of the top plate 13; the connecting cover 2 14 covers the outside of the connecting cover 12 and is connected by the connector 2. The filler 1 adopts a split design, which can be quickly disassembled and installed. The staff can directly open the top plate 13 and the connecting cover 2 14 to visually inspect the filter media caking and perform local cleaning or replacement of the blocked areas, which greatly simplifies the filter media filling, replacement and equipment maintenance process.

[0023] To further explain, both the bottom plate 11 and the top plate 13 are pyramidal in shape, and each has multiple through-slots 15 formed thereon. These through-slots 15 are elongated, with their long axes parallel to the inclination direction of the pyramidal slope. This allows material to flow along the slope of the pyramid and seep down through the through-slots 15. The slope guides the material to flow in multiple directions, ensuring uniform penetration into the filter media layer and preventing uneven filtration caused by localized concentration. The combined arrangement of the bottom plate 11, top plate 13, and through-slots 15 increases the contact area between the material and the filter media, ensuring that each portion of the filter media can fully perform its retention function, thereby improving the overall filtration efficiency.

[0024] To further explain, the top plate 13 has multiple transition grooves 16 at its upper end; the multiple transition grooves 16 are connected to multiple through grooves 15 in a one-to-one correspondence; the cross-section of the transition grooves 16 is arc-shaped. This allows materials to flow into the transition grooves 16 first, and then flow into the through grooves 15 after the transition grooves 16 are full of materials.

[0025] To further explain, multiple sets of filler 1 are provided; these multiple sets of filler 1 are stacked layer by layer. Each set of filler 1 is filled with materials of different particle sizes, with the filter media particle size decreasing from top to bottom. The coarse-diameter filter media intercepts large particle impurities, reducing the risk of clogging by the fine-diameter filter media; the fine-diameter filter media further intercepts small particles, improving filtration accuracy. A fixing frame 17 is fixedly provided at the upper end of the connecting cover 2 14. When multiple sets of filler 1 need to be stacked layer by layer, the upper filler 1 can be inserted into the fixing frame 17 provided at the upper end of the lower filler 1, which can make the multiple sets of filler 1 securely connected and prevent the upper filler 1 from falling due to instability. The fixing frame 17 has an opening 18, which can be clamped to facilitate the movement or handling of the filler 1.

[0026] Further explanation: Multiple sets of connectors 2 are arranged in a circular array around the filler 1. The side wall of the connecting cover 14 has a slot 21; the side wall of the connecting cover 12 has a slot 22; the connector 2 includes a plate 23; the plate 23 is inserted into the slots 21 and 22. After the connecting cover 14 is placed over the connecting cover 12, the connecting cover 12 and the connecting cover 14 can be fixedly connected by sequentially inserting the plate 23 into the slots 21 and 22, facilitating the movement and handling of the filler 1. A handle 24 is fixedly provided on the side wall of the plate 23. A rotating plate 25 is rotatably provided on the side wall of the connecting cover 14; a latch 26 is provided on the rotating plate 25; the rotating plate 25 engages with the latch 26. After inserting the insert plate 23 into slot 1 21 and slot 2 22 in sequence, rotate the rotating plate 25 so that the rotating plate 25 is embedded in the bayonet 26, which can limit the insertion plate 23 and prevent the insertion plate 23 from falling out of slot 1 21 and slot 2 22.

[0027] The working principle of this utility model is as follows: During operation, filter media is first filled into the base plate 11 and connecting cover 12, and then connecting cover 14 is placed over the outside of connecting cover 12. Next, insert plates 23 are inserted into slots 21 and 22 in sequence, and rotating plate 25 is rotated to embed into slot 26, which limits the insertion plates 23, thereby fixing connecting cover 12 and connecting cover 14 together to facilitate the movement and handling of the filler 1. Finally, multiple sets of filler 1 are stacked layer by layer. The upper filler 1 can be inserted into the fixing bracket 17 set at the upper end of the lower filler 1, which can make multiple sets of filler 1 firmly connected and prevent the upper filler 1 from falling due to instability. Each set of filler 1 is filled with materials of different particle sizes, and the particle size of the filter media decreases from top to bottom. The coarse-particle filter media intercepts large particles of impurities, reducing the risk of clogging of the fine-particle filter media; the fine-particle filter media further intercepts small particles, improving the filtration accuracy.

[0028] Finally, multiple sets of packing elements 1 are placed into the deep bed, and the material is poured into the deep bed, allowing the material to flow from top to bottom. The material can flow along the inclined surfaces of the bottom plate 11 and top plate 13 pyramids, and seep down along the through groove 15. The inclined surfaces guide the material to flow in multiple directions, allowing the material to permeate evenly into the filter media layer and avoiding uneven filtration caused by local concentration. The coordinated arrangement of the bottom plate 11, top plate 13, and through groove 15 increases the contact area between the material and the filter media, ensuring that the filter media can fully perform its retention function, thereby improving the overall filtration efficiency.

[0029] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
