[0030] EMBODIMENT

[0031] In order to solve the series of problems existing in the layered purification device in the prior art, with reference to Figures 1-6As shown, the application discloses a layered purification device, which comprises a purification box 10, the inside of the purification box 10 is divided into two purification chambers 12 by a vertical partition plate 11, sewage can be purified in layers only through one of the two purification chambers 12 each time, when one of the two purification chambers 12 is maintained or cleaned, the other purification chamber 12 is used, so that the sewage can be continuously cleaned; the specific structure in the purification chamber 12 is as follows, three windows 13 are formed in the side wall of the purification chamber 12 opposite to the vertical partition plate 11, and support blocks 14 are arranged on the two inner walls of the purification chamber 12 corresponding to the three windows 13;

[0032] Two filter assemblies 20, the filter assembly 20 comprises three water filtering grooves 21, a coarse mesh filter screen plate 22, a fine mesh filter screen plate 23 and an activated carbon filter plate 24, the three water filtering grooves 21 are slidably arranged on the corresponding support blocks 14 at the three windows 13, the lower part of the three water filtering grooves 21 is connected with a water filtering port 212, a water flow sensor 213 is arranged on the water filtering port 212, and the coarse mesh filter screen plate 22, the fine mesh filter screen plate 23 and the activated carbon filter plate 24 are sequentially arranged in the three water filtering grooves 21 from top to bottom.

[0033] Two sealing assemblies 30, the sealing assembly 30 comprises three sealing plates 33, and the three sealing plates 33 are detachably fixed outside the three windows 13 of the purification chamber 12.

[0034] Based on the above structure, when the sewage is purified in layers, one purification chamber 12 is used first, when the sewage enters the purification chamber 12, the sewage is filtered through the three water filtering grooves 21, the coarse mesh filter screen plate 22, the fine mesh filter screen plate 23 and the activated carbon filter plate 24 in sequence, and the corresponding water flow sensor 213 detects the water flow in real time during the flow of the sewage, if the water flow detected by the water flow sensor 213 is lower than a preset value range, the corresponding filter plate is blocked, at this time, the operator needs to replace it, and another purification chamber 12 needs to be used to continue purifying the sewage according to the above process.

[0035] In addition to the above structure, the application is provided with a water inlet pipe 17 in the middle of the top of the purification box 10, a water inlet transition cavity 15 is arranged in the inner top wall of the purification box 10, water injection ports 151 are formed in the water inlet transition cavity 15 corresponding to the two purification chambers 12, and first one-way valves 152 are arranged in the water injection ports 151.

[0036] A water outlet transition cavity 16 is arranged in the middle of the bottom of the purification box 10, water outlet ports 161 are formed in the water outlet transition cavity 16 corresponding to the two purification chambers 12, and second one-way valves 162 are arranged in the water outlet ports 161.

[0037] In the implementation process, the sewage to be purified and filtered is injected into the water inlet transition chamber 15 through the water inlet pipe 17. When a first one-way valve 152 is opened, the corresponding purification chamber 12 is enabled, and the sewage in the water inlet transition chamber 15 enters the purification chamber 12 correspondingly. The sewage is filtered by the coarse mesh filter screen plate 22, the fine mesh filter screen plate 23, and the activated carbon filter plate 24 in sequence to achieve layered filtration (the coarse mesh filter screen plate 22 is used to filter large-particle impurities, the fine mesh filter screen plate 23 is used to filter small-particle impurities, and the activated carbon filter plate 24 is used to remove color and odor), and the filtered sewage enters the water outlet transition chamber 16. When the corresponding second one-way valve 162 in the purification chamber 12 is opened, the purified sewage can be discharged. During the sewage purification process, if the water flow detected by the corresponding water flow sensor 213 is lower than the preset value, it indicates that the corresponding filter plate is blocked on a large scale. Therefore, the corresponding filter plate needs to be replaced or cleaned. In order to continuously purify the sewage, another first one-way valve 152 is controlled to be opened to make the sewage in the water inlet transition chamber 15 flow into the other purification chamber 12.

[0038] In order to facilitate the operator to monitor and control the two purification chambers 12 to be used alternately, a PLC controller 40 electrically connected with the water flow sensor 213, the first one-way valve 152, and the second one-way valve 162 and a display screen 50 electrically connected with the PLC controller 40 are arranged on the outside of the purification tank 10. In the implementation, the water flow detected by each water flow sensor 213 is displayed on the display screen 50, and the PLC controller 40 controls the two first one-way valves 152 and the two second one-way valves 162 to be used alternately according to the water flow value detected by the water flow sensor 213.

[0039] In the embodiment, a step 214 is arranged in the water filter groove 21, and the coarse mesh filter screen plate 22, the fine mesh filter screen plate 23, and the activated carbon filter plate 24 are fixed to the step 214 in the three water filter grooves 21 by bolts. When the coarse mesh filter screen plate 22, the fine mesh filter screen plate 23, and the activated carbon filter plate 24 are blocked on a large scale and the flowing water flow is small, the operator can quickly disassemble and replace them.

[0040] In order to facilitate the operator to take out the water filter groove 21 from the purification chamber 12, a sliding groove 141 is formed in the supporting block 14, and a sliding block 211 is arranged at the bottom of the water filter groove 21 and slides in the sliding groove 141. In actual use, the operator only needs to pull the water filter groove 21 to take it out, which is quick and efficient and has high practicality.

[0041] In the embodiment, the hollow connecting plate 31 is arranged outside the window 13, the sealing plate 33 is fixed to the hollow connecting plate 31 through bolts, and the rubber pad 32 is arranged between the sealing plate 33 and the hollow connecting plate 31. In this way, the window 13 is tightly sealed, the sealing plate 33 can be quickly disassembled by the operator, and the coarse hole filter screen plate 22, the fine hole filter screen 23 or the activated carbon filter plate 24 can be quickly replaced.
