[0035] As Figures 1-3 shown, this embodiment provides a cooling water filtering device, which includes a first water outlet pipe 1, a grid filtering mechanism 2, and a spiral filtering mechanism 3. The grid filtering mechanism 2 includes a receiving bin 21, a grid filtering component 22, a driving component 23, and a cleaning component 24. The driving component 23 includes a first motor 231, two drums 232 respectively arranged at both ends of the receiving bin 21, and a chain. The chain is arranged on the two drums 232 to make them rotate synchronously. The grid filtering component 22 includes a filtering grid 221. The filtering grid 221 surrounds the two drums 232 and can move under the action of the driving component 23.

[0036] One end of the receiving bin 21 corresponds to the first water outlet pipe 1. The bottom of the receiving bin 21 at the corresponding position of the first water outlet pipe 1 has an opening, and the opening communicates with a second water collecting component 26. The other end of the receiving bin 21 extends to a collecting component 25.

[0037] The cleaning component 24 includes a hole cleaner and a slag scraping brush 241. The hole cleaner is arranged inside the rotation path of the filtering grid 221 and rotates synchronously in contact with the grid. The specific structure is a roller with the same width as the filtering grid 221. Cleaning protrusions are arranged on the roller along the direction of the grid gaps. During the synchronous rotation with the filtering grid 221, the hole cleaner cleans the gaps of the filtering grid 221 from the inside to the outside; the slag scraping brush 241 is closely arranged below one end of the filtering grid 221 close to the collecting component 25 to sweep and clean the filtering grid 221.

[0038] The collection component 25 includes a slag collection tank 251, a bottom plate 252, and a hydraulic rod. One side of the bottom plate 252 is hinged to the slag collection tank 251. One end of the hydraulic rod is hinged to the middle of the slag collection tank 251, and the other end is hinged to the bottom plate 252. The bottom plate 252 can be opened or closed relative to the slag collection tank 251.

[0039] The second water collection component 26 includes a second water collection tank 261 and a second drain pipe 262. The second water collection tank 261 is communicated with the bottom opening of the accommodation bin 21, and the second drain pipe 262 is communicated with the spiral filtering mechanism 3.

[0040] As Figures 5-6 shown, the spiral filtering mechanism 3 includes a casing 31, a filtering component 32, and a spiral blade 331. The filter cylinder 321 is a mesh filter cylinder 321. The filtering component 32 includes a filter cylinder 321 and a filter chamber 322. The filter chamber 322 is hermetically connected to the casing 31 and forms a water passing space with the filter cylinder 321. The filter chamber 322 is provided with a second outlet 343 and is communicated with the third drain pipe. The spiral blade 331 is arranged inside the spiral filter and extends from the first inlet 341 at the lower end of the casing 31 to the first outlet 342 at the upper end. A second driving component 23 for driving the spiral filtering mechanism 3 is arranged at the upper end of the casing 31. The second driving component 23 includes a second motor and a second transmission member.

[0041] As Figure 1 and Figure 7 shown, in terms of the overall installation of the equipment, the cooling water filtering equipment further includes a chassis 51 and a frame 52. The installation surface of the chassis 51 has a certain height. The grille filtering mechanism 2 and the spiral filtering mechanism 3 are arranged on the chassis 51 and covered by the frame 52. A bracket 53 is provided between the spiral filtering mechanism 3 and the chassis 51, so as to be arranged obliquely upward. The first outlet 342 at the end of the spiral filtering mechanism 3 extends to the slag collection tank 251.

[0042] As Figure 4 shown, the cooling water filtering equipment further includes a fourth flushing component. The fourth flushing component includes a fourth suction pipe 41 communicated with the water passing space of the filter chamber 322, a fourth water pump 42, and a fourth flushing nozzle 43. The fourth flushing nozzle 43 is aligned with the filter grille 221.

[0043] The cooling water filtering equipment further includes a liquid level sensor, a material sensor, and a measurement and control device. The liquid level sensor is arranged in the second water collection tank 261 and the spiral filtering mechanism 3, and the material sensor is arranged in the collection component 25. The measurement and control device is communicatively connected with the backwashing device and the cleaning component 24.

[0044] The working process of the cooling water filtering device is as follows: The cooling water enters the filtering grille 221 of the grille filtering mechanism 2 from the first water outlet pipe 1. The cooling water and impurities are preliminarily separated and enter the second water collecting component 26 below the grille filter. The impurities are transmitted through the filtering grille 221 and fall into the slag collecting box 251.

[0045] The preliminarily filtered water enters the spiral filtering mechanism 3 from the second water collecting component 26, and the secondary separation of the cooling water and impurities is realized under the action of the filtering cylinder 321. The cooling water enters the water passing space of the filtering chamber 322 and is recycled after being discharged from the third drain pipe. The impurities separated secondly are transmitted to the first outlet 342 by the rotation of the spiral blade 331 and then fall into the slag collecting box 251.

[0046] When the liquid level sensor of the second water collecting tank 261 reaches the warning water level or the filtering grille 221 needs to be cleaned, the measurement and control device controls the fourth water pump 42 to pump the filtered water out of the filtering chamber 322 to the fourth flushing nozzle 43 to perform back flushing on the filtering grille 221. At the same time, the measurement and control device can also control the slag scraping brush 241 and the hole cleaning device to clean the filtering grille 221.

[0047] When the impurities in the slag collecting box 251 need to be transported, the hydraulic rod is controlled to open the bottom plate 252, and the filtered impurities can directly fall into the transportation equipment for subsequent treatment.

[0048] The specific embodiments of the present utility model have been described above. Through the above description, relevant staff can make various changes and modifications completely within the scope of not deviating from the technical idea of this invention.
