DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Combine the following Figures 1 to 8 The invention describes a food processing wastewater treatment device based on high-efficiency activated carbon.

[0020] like Figures 1 to 3As shown, in one embodiment, a food processing wastewater treatment device based on high-efficiency activated carbon includes a rotating disk 200, a plurality of first activated carbon filter cartridges 300 and a plurality of second activated carbon filter cartridges 400; the rotating disk 200 can be rotated unidirectionally or reciprocatingly, the middle part of the rotating disk 200 is set as a water storage chamber 210, and the periphery of the water storage chamber 210 is sequentially provided with a first annular chamber 220 and a second annular chamber 230, a plurality of first installation chambers 253 are arranged in an annular array at the junction of the first annular chamber 220 and the second annular chamber 230, and a plurality of second installation chambers 263 are arranged in an annular array at the outer edge of the second annular chamber 230; the plurality of first activated carbon filter cartridges 300 are respectively installed in the plurality of first installation chambers 253, and are used to filter the wastewater entering the second annular chamber 230 from the first annular chamber 220; the plurality of second activated carbon filter cartridges 400 are respectively installed in the plurality of second installation chambers 263, and are used to filter the wastewater discharged from the second annular chamber 230 to the designated water storage place.

[0021] The above-mentioned food processing wastewater treatment device based on high-efficiency activated carbon injects wastewater into the water storage chamber 210 when in use. The wastewater in the water storage chamber 210 will enter the first annular chamber 220 under the influence of gravity. A plurality of first installation chambers 253 are arranged at the junction of the first annular chamber 220 and the second annular chamber 230. A first activated carbon filter cartridge 300 is installed in each first installation chamber 253. In the first state, wastewater can enter the second annular chamber 230 through the first activated carbon filter cartridge 300. In the second state, the first activated carbon filter cartridge 300 can seal the first installation chamber 253 to prevent wastewater from entering the second annular chamber 230. Entering the second annular cavity 230, the second activated carbon filter cartridge 400 in the second installation cavity 263 also has two states, which are respectively used to discharge the wastewater to the designated water storage place outside the rotating disk 200, or to close the second installation cavity 263. Since the rotating disk 200 can rotate when in use, the centrifugal force can be used to increase the wastewater treatment rate when treating the wastewater. At the same time, the state of the first activated carbon filter cartridge 300 and the second activated carbon filter cartridge 400 can be adjusted according to the needs of use to change the wastewater treatment position, which is convenient for replacement or maintenance of the device parts and is more convenient to use.

[0022] In one embodiment, the first activated carbon filter cartridge 300 and the second activated carbon filter cartridge 400 are staggered with each other in the circumferential direction of the rotating disk 200 .

[0023] Specifically, since the first annular cavity 220 is located in the inner circle of the second annular cavity 230, and since there is a gap between the two, the outer diameter of the first annular cavity 220 is smaller than the inner diameter of the second annular cavity 230. At the same time, the setting of the first mounting cavity 253 and the second mounting cavity 263 requires occupying a certain space. Therefore, the first mounting cavity 253 and the second mounting cavity 263 need to be staggered in the circumferential direction of the rotating disk 200. Specifically, it can be understood that if the rotating disk 200 is regarded as a 360-degree plane, and the first mounting cavity 253 and the second mounting cavity 263 are each provided with six, the angle between two adjacent first mounting cavities 253 and two adjacent second mounting cavities 263 is 60 degrees. If the first mounting cavity 253 is at the 0 degree and 60 degree positions, the second mounting cavity 263 is at the 30 degree position. This position structure setting enables the wastewater to flow relatively smoothly when the rotating disk 200 rotates.

[0024] In one embodiment, the central axis of the rotating disk 200 is set horizontally, and a fixed seat 110 is set on one side of the rotating disk 200. The fixed seat 110 has a plurality of fixed rods 120 arranged in a circular array. The fixed rods 120 pass through the rotating disk 200. A flange 130 is installed at one end of the fixed rod 120 away from the fixed seat 110, and the flange 130 is fixed by installing bolts on the end of the fixed rod 120.

[0025] Specifically, a driving device is disposed on the fixing seat 110 , and a driving end of the driving device is connected to a plurality of fixing rods 120 . The fixing rods 120 are used to limit and fix the rotating disk 200 , so that the driving device can drive the rotating disk 200 to rotate.

[0026] In one embodiment, a first activated carbon filter plate 240 is disposed at the junction of the water storage cavity 210 and the first annular cavity 220 . The first activated carbon filter plate 240 is configured as an annular plate structure, and a plurality of filter holes 241 are disposed on the first activated carbon filter plate 240 .

[0027] Specifically, the first activated carbon filter plate 240 separates the water storage chamber 210 and the first annular chamber 220 in the rotating disk 200, and can perform primary treatment on the wastewater entering the water storage chamber 210. At the same time, the setting of the filter hole 241 allows the wastewater to slowly flow into the first annular chamber 220 without passing through the first activated carbon filter plate 240, thereby avoiding the first activated carbon filter plate 240 from being unable to discharge water due to blockage. Combined with the centrifugal force generated by the rotation of the rotating disk 200, the water discharge effect is better.

[0028] It should be noted that the rotating disk 200 can be configured as two parts, one part of which is a disc-shaped water storage chamber 210, and the other part is a ring-shaped first annular chamber 220 and a second annular chamber 230, which are connected and fixed by threaded fastening or any other means. This structural setting makes the first activated carbon filter plate 240 a detachable structure, and the first activated carbon filter plate 240 can be disassembled after the rotating disk 200 is disassembled.

[0029] In one embodiment, a water inlet 211 and a plurality of through holes 212 are provided on one side of the water storage chamber 210 . The plurality of through holes 212 are arranged in a circular array around the water inlet 211 . The water inlet 211 is used for waste water to enter.

[0030] like Figure 4 As shown, in one embodiment, a plurality of first arc plates 251 are provided at the junction of the first annular cavity 220 and the second annular cavity 230. The plurality of first arc plates 251 are arranged in an annular array with intervals therebetween. An arc expansion plate 252 is provided at the end of the first arc plate 251. The arc opening of the arc expansion plate 252 faces a direction away from the first arc plate 251. A first installation cavity 253 is formed between two arc expansion plates 252 with arc openings facing each other. A first opening 254 of the first installation cavity 253 is formed between the side ends of the two arc expansion plates 252.

[0031] Specifically, Figure 6 As shown, in one embodiment, the first activated carbon filter cartridge 300 includes a first bottom plate 310, a first tube body 320, a first top plate 330 and a second activated carbon filter plate 340, the first bottom plate 310 is fixed to one end of the first tube body 320, the first top plate 330 is detachably fixed to the other end of the first tube body 320, and two third openings 321 are relatively opened on the first tube body 320, and the second activated carbon filter plate 340 is detachably installed in the third openings 321.

[0032] Specifically, when the first activated carbon filter cartridge 300 is rotated to a set angle such as 90 degrees, the two third openings 321 will face the two arc-shaped expansion plates 252 respectively, thereby forming a partition between the first annular cavity 220 and the second annular cavity 230 .

[0033] like Figure 7 As shown, in one embodiment, the first protrusion 322 is provided on both sides of the third opening 321, and the second protrusion 341 and the third protrusion 342 are provided on both side ends of the second activated carbon filter plate 340, and the second protrusion 341 and the third protrusion 342 are adjacent to each other and clamp the first protrusion 322 in the middle.

[0034] Specifically, the second protrusion 341 and the third protrusion 342 are both elastic, so when the second activated carbon filter plate 340 is installed, it only needs to be pressed. During the pressing process, contact deformation occurs between the third protrusion 342 and the first protrusion 322 until the third protrusion 342 passes over the first protrusion 322, and the second protrusion 341 and the third protrusion 342 are respectively attached to the two sides of the first protrusion 322. At this time, the second protrusion 341 and the third protrusion 342 form a clamp for the first protrusion 322, and the clamping force is such that it will not loosen even if it is impacted by water flow, and will only be disassembled under human intervention and concentrated force.

[0035] like Figure 5 As shown, in one embodiment, a plurality of second arc plates 261 are arranged in an annular array on the outer edge of the second annular cavity 230, and the plurality of second arc plates 261 are arranged in an annular array with intervals therebetween, and a cylindrical expansion plate 262 is fixed between two adjacent second arc plates 261, and a second installation cavity 263 is formed inside the cylindrical expansion plate 262, and a second opening 264 is provided on the side of the cylindrical expansion plate 262 facing the first arc plate 251.

[0036] Specifically, Figure 8 As shown, in one embodiment, the second activated carbon filter cartridge 400 includes a second bottom plate 410, a second tube body 420, a second top plate 430 and a third activated carbon filter plate 440; the second bottom plate 410 is fixed to one end of the second tube body 420, the second top plate 430 is fixed to the other end of the second tube body 420, the second top plate 430 is arranged in an annular structure, and a fourth opening 421 is opened on the second tube body 420, and the third activated carbon filter plate 440 is detachably installed in the fourth opening 421.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
