[0027] according to Figure 1-8This embodiment provides a slag grinding circulating water treatment and filtration device, including a frame 1, on which a controller 10 is fixedly mounted, and on which a sedimentation tank 2, a cleaning tank 3, a reverse osmosis tank 4, and a water storage tank 5 are fixedly mounted. The cleaning tank 3 includes a box cover 31 and a box body 32, and the box cover 31 and the box body 32 are movably mounted. A fixed shaft 312 is fixedly mounted on the box cover 31, and a filter plate 313 is fixedly mounted on the fixed shaft 312. The lower side of the filter plate 313 is in contact with the bottom of the box body 32. The filter plate 313 is made of activated carbon, which is a material with a highly porous structure and adsorption capacity. By filling the filter plate 313 with activated carbon, when the circulating water passes through the filter plate 313, impurities will be adsorbed by the activated carbon and remain on the filter plate 313, thereby achieving the purification of the circulating water. The box body 32 is fixedly installed with an inlet pipe 321, an outlet pipe 322, and a return pipe 323. The sedimentation tank 2 is fixedly connected to the inlet pipe 321. The frame body 1 is fixedly installed with a pump 3211. The pump 3211 is connected in series to the inlet pipe 321. The water in the sedimentation tank 2 is pumped into the cleaning tank 3 through the pump 3211. The outlet pipe 322 and the return pipe 323 are fixedly connected to the reverse osmosis tank 4 through a three-way valve 324. A pump 2 3221 is fixedly installed on the frame 1, and the pump 2 3221 is connected in series to the water outlet pipe 322. A water quality detector 6 is fixedly installed on the water outlet pipe 322. The water quality detector 6 is installed on the side of the water outlet pipe 322 close to the cleaning tank 3. The cleaned circulating water is pumped into the reverse osmosis tank 4 through the pump 2 3221. The reverse osmosis tank 4 is a RO water tank. The membrane separation technology is applied by the reverse osmosis equipment to effectively remove charged ions, inorganic matter, colloidal particles, bacteria and organic matter in the water. The water quality of the pumped circulating water is detected by the water quality detector 6, thereby preventing the circulating water from being cleaned. The water cannot be cleaned properly, which reduces the cleaning quality of the circulating water, and the circulating water is re-pumped into the cleaning tank 3 through the three-way valve 1 324. The reverse osmosis tank 4 is fixedly equipped with a pipe 1 325 and a return pipe 2 326. The pipe 1 325 and the return pipe 2 326 are fixedly connected to the water storage tank 5. A water quality detector 2 7 is fixedly installed in the water storage tank 5. A pump 3 3251 and a solenoid valve 3 327 are fixedly installed on the return pipe 2 326. The circulating water in the filtered water storage tank 5 is detected by the water quality detector 2 7, and re-enters the reverse osmosis tank 4 through the pump 3251 and the solenoid valve 3 327 on the return pipe 2 326 for filtration.

[0028] A retention plate 21 is slidably connected to the sedimentation box 2, and a clamping rod 22 is fixedly installed on the sedimentation box 2. The large particles in the circulating water are preliminarily separated by the retention plate 21, so that the large particles can be retained on the retention plate 21. A plurality of grooves 221 are provided on the clamping rod 22. A solenoid valve 23 is fixedly installed on the sedimentation box 2 for discharging sewage from the sedimentation box 2.

[0029] Two connecting rods 212 are fixedly installed on the retention plate 21, and a groove 213 is provided on the connecting rod 212. The groove 213 is slidably connected to a block 214. A spring 215 is provided in the groove 213. One end of the spring 215 is fixedly connected to the connecting rod 212, and the other end is fixedly connected to the block 214. A pull rod 216 is fixedly installed on one end of the block 214, and the pull rod 216 is slidably connected to the connecting rod 212.

[0030] The clamping block 214 is clamped and connected with the second groove 221 , so that the retention plate 21 is easy to disassemble and the large particles on the retention plate 21 are cleaned.

[0031] The water storage tank 5 is provided with a second electromagnetic valve 51 to facilitate drainage of the water storage tank 5 .

[0032] The controller 10 is electrically connected to the three-way valve 1 324, pump 1 3211, pump 2 3221, pump 3 3251, water quality detector 1 6, water quality detector 2 7, solenoid valve 1 23, solenoid valve 2 51, and solenoid valve 3 327. The controller 10 directly controls each component through the signal fed back by the water quality detector 6. The three-way valve 1 324 and pump 3 3251 are both electric three-way valves.

[0033] A bracket 11 is fixedly mounted on the frame 1 , and the box 32 is fixedly connected to the bracket 11 .

[0034] The specific operation is as follows: the circulating water is injected into the sedimentation tank 2, and the circulating water is injected from the side of the sedimentation tank 2 where the clamping rod 22 is installed. The large particles in the circulating water are preliminarily separated by the retention plate 21 on the sedimentation tank 2. After the circulating water is fully precipitated, the controller controls the pump 1 3211 to work, and the circulating water is pumped into the cleaning tank 3 through the pump 1 3211, so that the filter plate 313 adsorbs the impurities in the circulating water to purify the circulating water. The pump 2 3221 is started to pump the circulating water out of the cleaning tank 3. At the same time, the water quality detector 1 6 detects the pumped circulating water and continuously feeds back the signal to the controller 10. The controller 10 controls the three-way valve 1 324 to pump the circulating water into the reverse osmosis tank 4. The reverse osmosis tank 4 removes the charged ions, inorganic matter, colloidal particles, bacteria and organic matter in the water, and then the circulating water is pumped into the water storage tank 5 through the pump 3 3251.

[0035] If the water quality detector 16 detects that the water quality of the pumped-out circulating water is unqualified, a signal is fed back to the controller 10. The controller 10 controls the three-way valve 1 324 to allow the circulating water to flow back into the cleaning tank 3 through the return pipe 1 323 and turns off the pump 1 3211. If the water quality detector 16 detects that the water quality of the circulating water is unqualified for a long time, the controller 10 controls the pump 2 3221 to stop working, clean the cleaning tank 3, and treat the filter plate 313 at the same time so that the filter plate 313 can filter again. After the replacement is completed, the pump 1 3211 and the pump 2 3221 are restarted to clean the circulating water and perform real-time testing through the water quality detector 16. If it is detected that the treated circulating water still does not meet the standard, the pump 1 3211 and the pump 2 3221 are controlled to stop working and the sedimentation tank 2 is cleaned.

[0036] If the circulating water in the water storage tank 5 is detected to be of unqualified quality, the controller 10 controls the electromagnetic valve 3 327 and the pump 3 3251 to work, and stops other components, and the circulating water re-enters the reverse osmosis tank 4 through the return pipe 2 326 for filtration.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
