Description

Technical Field

[0001] The utility model relates to the field of activated carbon processing equipment, in particular to an inclined plate activated carbon water filtering tank. Background Art

[0002] Activated carbon has been used to purify water for a long time. The porous nature of activated carbon has a good adsorption effect on organic matter, colloids, microorganisms, residual chlorine, etc. in water, thereby achieving the purpose of deep water purification. The adsorption capacity of activated carbon has a certain saturation value. After saturation, activated carbon needs to be activated and regenerated (desorbed) to restore its adsorption performance, so as to achieve the purpose of repeated use.

[0003] In the water treatment process, activated carbon contains a large amount of water after adsorption (saturated carbon) or desorption (regenerated carbon). Since dry activated carbon is easy to carry and can shorten the desorption time, a large amount of water needs to be filtered out to obtain relatively dry activated carbon, so activated carbon dehydration equipment is needed.

[0004] Existing activated carbon dehydration equipment mainly includes centrifugal rotating dehydration devices (such as Chinese invention patent CN113028747A), raw material extrusion dehydration equipment (such as Chinese invention patent CN110715513B) and vacuum dehydration devices (such as Chinese invention patent CN104474766A), etc. These activated carbon dehydration equipment all need to provide power to complete the dehydration work, such as rotating centrifugal, extrusion or vacuum operation to dehydrate, which has high energy consumption.

[0005] The applicant uses a water filter tank to filter activated carbon containing a large amount of water, and can filter out a large amount of water without providing power to obtain relatively dry activated carbon. Figure 1 As shown, the water filter tank currently used by the applicant uses a flat filter plate to filter the water-containing activated carbon. The flat filter plate is provided with a number of water caps. Since the gaps in the water caps are not enough for the activated carbon to pass through, the water will flow out from the water caps and out through the drain port at the bottom of the water filter tank; the center of the flat filter plate is connected to the activated carbon outlet at the bottom of the water filter tank. Since the flat filter plate is a flat plate, the activated carbon after filtering the water cannot be completely discharged from the activated carbon outlet, and some carbon will be deposited on the flat filter plate, especially the closer to the inner wall of the tank, the greater the amount of deposition. In order to solve this problem, the applicant has improved the structure of the water filter tank. Utility Model Content

[0006] In order to solve the above problems, the utility model provides an inclined plate activated carbon water filter tank, which can avoid the problem of activated carbon depositing on the filter plate.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] The utility model provides an inclined plate activated carbon water filter tank, comprising a tank body, an activated carbon inlet is provided on the top of the tank body, an activated carbon outlet and a drain are provided on the bottom of the tank body, a funnel-shaped water filter structure is provided at the lower part of the tank body, and the bottom of the water filter structure is connected to the activated carbon outlet; the water filter structure is formed by connecting a plurality of fan-shaped inclined filter plates in sequence, and the inclined filter plates are inclined against the inner wall of the tank body and form an angle of 50 to 60 degrees with the horizontal plane; a plurality of water cap mounting holes are provided on the inclined filter plates, and water caps that only allow water to pass through are installed on the water cap mounting holes.

[0009] Through the above technical scheme, a water filtration structure composed of several inclined filter plates is used to replace the existing flat filter plates. Since the inclined filter plates form an angle of 50 to 60 degrees with the horizontal plane, the activated carbon can automatically slide down from the inclined filter plates under the action of gravity after filtering water through the water cap and be discharged from the activated carbon outlet, thereby avoiding the deposition of activated carbon on the inclined filter plates.

[0010] Furthermore, the inclined filter plate is fan-shaped as a whole and has a bilaterally symmetrical structure, with an arc-shaped edge on the top, a horizontal straight edge on the bottom, and beveled edges on the left and right sides. The left beveled edge connects the arc-shaped edge and the left end of the straight edge, and the right beveled edge connects the arc-shaped edge and the right end of the straight edge.

[0011] Furthermore, the bottom of the water filtration structure is a carbon outlet, which is surrounded by the bottom straight edges of multiple inclined filter plates, and the bottom straight edges of all inclined filter plates are located in the same horizontal plane. The carbon outlet is connected to the activated carbon outlet at the bottom of the tank.

[0012] Furthermore, the activated carbon outlet is opened at the center of the bottom of the tank.

[0013] Through the above three sets of technical solutions, the fan-shaped inclined filter plate can ensure that the enclosed water filtering structure is funnel-shaped or pyramid-shaped, so that the carbon outlet is located at the center of its bottom, and the carbon outlet is located directly above the activated carbon outlet. When the water of the activated carbon is filtered out from the water cap, the valve on the activated carbon outlet is opened, and the activated carbon enters the activated carbon outlet from the carbon outlet and is discharged out of the tank.

[0014] Furthermore, a plurality of rows or columns of water cap mounting holes are provided in the middle and lower parts of the inclined filter plate, and the water cap mounting holes in each row or column are arranged neatly or staggered on the inclined filter plate.

[0015] Through the above technical solution, the water caps can be evenly distributed in the middle and lower parts of the inclined filter plates, so as to better contact with the water-carrying activated carbon and improve the water filtering effect.

[0016] Furthermore, a filter plate support is provided in the tank body, the bottom of the filter plate support is fixedly connected to the bottom of the tank body, and the top of the filter plate support is fixedly connected to the bottom surface of the inclined filter plate.

[0017] Furthermore, the position of the water cap mounting hole on the inclined filter plate avoids the connection position between the filter plate support and the inclined filter plate.

[0018] Through the above technical solution, the inclined filter plate can be supported and fixed by the filter plate support member to keep it in an inclined state, and the water cap avoids the connection portion between the inclined filter plate and the filter plate support member.

[0019] Furthermore, a tank support is provided at the lower portion of the tank body.

[0020] Through the above technical solution, the tank body support can fix and support the tank body, so that the tank body remains in a vertical state.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] The utility model provides an inclined plate activated carbon water filter tank, which adopts a funnel-shaped water filter structure to replace the existing flat filter plate. The water filter structure is formed by connecting a plurality of fan-shaped inclined filter plates. A plurality of water caps are installed on the inclined filter plates. After the activated carbon with water falls on the inclined filter plates, the water flows away from the water caps. Since the inclined filter plates are inclined against the inner wall of the tank body at an angle of 50 to 60 degrees to the horizontal plane, the activated carbon after the water is filtered out will be automatically discharged from the carbon outlet under the action of its own gravity and will not be deposited on the inclined filter plates, thereby solving the problem of activated carbon deposition around the flat filter plates. And because the water filtration structure is a funnel-shaped three-dimensional structure, and the flat filter plate is a planar structure, the contact area between the activated carbon and the water filtration structure is significantly larger than the contact area with the flat filter plate; and when the spacing between water caps is equal, the total number of water caps on the three-dimensional water filtration structure is also significantly larger than the number of water caps on the flat filter plate. Therefore, compared with the flat filter plate, the improved water filtration structure not only increases the contact area with the activated carbon, but also increases the number of water caps. Therefore, replacing the flat filter plate with the water filtration structure can shorten the water filtration time and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The utility model is further described in detail below with reference to the accompanying drawings.

[0032] Figure 1 The flat activated carbon water filter tank previously used by the applicant has a flat filter plate 9 disposed at the bottom of the tank body 2, and a plurality of water caps 5 disposed on the flat filter plate 9. The activated carbon with water enters the tank body 2 from the activated carbon inlet 1 at the top of the tank body 2 and falls on the flat filter plate 9. The water flows out from the water cap 5 and flows out through the drain port 6 at the bottom of the tank body 2. The activated carbon after the water is filtered out is discharged from the central outlet of the flat filter plate 9 and discharged from the outside of the tank body 2 through the activated carbon outlet 4 at the bottom of the tank body 2. Since the flat filter plate 2 is disposed horizontally, when the granular activated carbon is discharged from the central outlet of the flat filter plate 9, part of the activated carbon will be deposited on the flat filter plate 9, and the activated carbon cannot be completely discharged. This deposition phenomenon will be particularly obvious at the connection between the flat filter plate 9 and the inner wall of the tank body 2. In order to solve this problem, the utility model improves the internal structure of the current water filter tank, and the specific technical scheme is as follows.

[0033] See also Figure 2-5 The utility model provides an inclined plate activated carbon water filter tank, comprising a tank body 2, the lower part of which is supported and fixed by a tank body support 8, so that the tank body 2 is kept in a vertical state. An activated carbon inlet 1 is provided at the top of the tank body 2, and an activated carbon outlet 4 and a drain outlet 6 are provided at the bottom of the tank body 2, and the activated carbon outlet 4 is provided at the center of the bottom of the tank body 2. A funnel-shaped (pyramid-shaped) water filter structure surrounded by a plurality of inclined filter plates 3 is provided inside the tank body 2, and the bottom of the water filter structure is a carbon outlet, which is connected to the activated carbon outlet 4. A plurality of water caps 5 are provided on the inclined filter plate 3. The inclined filter plate 3 is obliquely fixed to the lower part of the tank body 2 by the filter plate support 7, and the inclination angle of the inclined filter plate 3 is 50-60°, that is, the inclined filter plate 3 is at an angle of 50-60° with the horizontal plane. The bottom of the filter plate support 7 is fixedly connected to the bottom of the tank body 2, and the top of the filter plate support 7 is fixedly connected to the bottom surface of the inclined filter plate 3.

[0034] like Figure 4As shown, the inclined filter plate 3 is fan-shaped as a whole, and is a bilaterally symmetrical structure, with a circular arc edge at the top, a horizontal straight edge at the bottom, and oblique edges on the left and right sides, respectively connecting the left and right ends of the circular arc edge at the top and the straight edge at the bottom. The middle and lower parts of the inclined filter plate 3 are provided with a plurality of rows (or columns) of neatly (or staggered) arranged water cap mounting holes 11. In addition, the center position of the inclined filter plate 3 is not provided with a water cap mounting hole 11 in order to reserve this position for connection with the filter plate support 7, that is, the top of the filter plate support 7 is welded to the center position of the bottom surface of the inclined filter plate 3.

[0035] like Figure 3 As shown, the water cap 5 is a purchased finished part, and the water cap 5 is welded to the water cap mounting hole 11 of the inclined filter plate 3 to form intermittent welding points 10, and the gap of the water cap 5 can only allow water to pass through, but not enough to allow the activated carbon to pass through, so that water can be filtered out from the water cap 5, and the activated carbon remains on the inclined filter plate 3.

[0036] like Figure 5 As shown, taking four inclined filter plates 3 as an example, the water filtration structure is composed of four inclined filter plates 3, that is, the inclined sides of adjacent inclined filter plates 3 are connected together to form a three-dimensional water filtration structure in the shape of a quadrangular pyramid, and the bottom of the quadrangular pyramid water filtration structure is a square charcoal outlet, that is, the charcoal outlet is surrounded by the bottom straight sides of the four inclined filter plates 3, and the bottom straight sides of all the inclined filter plates 3 are located in the same horizontal plane, and the charcoal outlet is connected to the activated carbon outlet 4 at the bottom of the tank body 2.

[0037] In the utility model, the applicant changes the original flat filter plate 9 into a plurality of inclined filter plates 3, the top of the inclined filter plate 3 is inclined against the inner wall of the tank body 2 at an angle of 50 to 60 degrees to the horizontal plane ( Figure 2 ), and the oblique sides of the oblique filter plates 3 are connected in sequence to form a funnel-shaped (pyramidal) water filtering structure, and the oblique filter plates 3 are provided with water cap mounting holes 11 ( Figure 4 ), install the water cap 5 on the water cap mounting hole 11 of the inclined filter plate 3 ( Figure 3 ), so that the single filter plate becomes smaller and easier to install. The installation diagram is as follows Figure 5 Shown in stereogram.

[0038] The activated carbon with water enters the tank body 2 from the activated carbon inlet 1 through the transfer pipe and falls on the inclined filter plate 3. The water flows away from the water cap 5 and is discharged from the drain port 6. After the water is filtered out, the valve on the activated carbon outlet 4 is opened. The activated carbon will automatically slide down from the activated carbon outlet 4 due to its own gravity, and the activated carbon will not be deposited on the inclined filter plate 3.

[0039] The utility model replaces the flat filter plate 9 with a water filtering structure surrounded by a plurality of inclined filter plates 3. Since the water filtering structure is a funnel-shaped (pyramidal) three-dimensional structure, and the flat filter plate 9 is a planar structure, after the activated carbon falls on the water filtering structure and the flat filter plate 9 respectively, the contact area between the activated carbon and the water filtering structure is significantly larger than the contact area with the flat filter plate 9; and when the spacing between adjacent water caps 5 on the water filtering structure and the flat filter plate 9 is equal, the total number of water caps 5 on the three-dimensional water filtering structure is also significantly larger than the number of water caps 5 on the flat filter plate 9. Therefore, compared with the flat filter plate 9, the improved water filtering structure can shorten the water filtering time and improve the working efficiency.

[0040] The above is a further detailed description of the utility model in combination with a specific implementation method, and it cannot be determined that the specific implementation of the utility model is limited to this; for technical personnel in the field of the utility model and related technical fields, based on the technical solution of the utility model, the expansion and replacement of operating methods and data should all fall within the protection scope of the utility model.
