DETAILED DESCRIPTION

[0026] Please refer to Figure 1 This embodiment provides a circulating water filtering device, including an outer frame 100 and a filtering assembly 200.

[0027] Please refer to Figure 2 The outer frame 100 includes a top frame 110, a bottom frame 120 and two vertical frames 130. The two vertical frames 130 are fixedly connected between the top frame 110 and the bottom frame 120, and the two vertical frames 130 are arranged parallel to each other. The opposite sides of the two vertical frames 130 are the inner sides of the vertical frames 130, and the opposite sides of the two vertical frames 130 are the outer sides. Guide rails are arranged on the inner sides of the two vertical frames 130, and the guide rails are also arranged in the vertical direction.

[0028] Please refer to Figure 3 , the filter assembly 200 includes a mesh frame 210, a filter screen 220 and a receiving tank 230. Figure 1 and Figure 2 As shown, the grid 210 is installed in the enclosed area of ​​the outer frame 100, and the grid 210 can slide along the guide rail. Figure 1 and Figure 2 It can be seen that the filter assembly 200 has moved vertically. The filter screen 220 is installed on the grid frame 210, and the filter screen 220 is designed to have at least two layers of partition screens, wherein the outermost layer of the partition screen of the filter screen 220 is the first layer to be impacted by the incoming water.

[0029] The receiving trough 230 is installed on the grid 210 in the horizontal direction, and the receiving trough 230 is installed on the side where the outermost partition net is located. Figure 3 , Figure 6 and Figure 7 , Figure 6 A side view of the receiving trough 230 is shown. Figure 7 A top view of the receiving trough 230 is shown, in which the upper side of the receiving trough 230 is opened to facilitate the receiving trough 230 to smoothly receive impurities dropped from the filter screen 220 when the filter assembly 200 is moved up from the water; a plurality of through slots are provided on the bottom side of the receiving trough 230, and through slots may also be provided on other sides to facilitate water flow.

[0030] Compared with the currently used single-layer filter screen 220 at the outlet of the circulating water cooling pool, this solution improves the filtering effect, reduces the clogging of water-using equipment, and maintains stable operation of the equipment by setting at least two layers of filter screens 220 in the filter assembly 200.

[0031] When cleaning the filter screen 220 manually, the outer frame 100 remains stationary, the filter assembly 200 is lifted, and the mesh frame 210 of the filter assembly 200 moves upward along the slide rail of the vertical frame 130 of the outer frame 100. During the movement, the impurities falling from the filter screen 220 will directly fall into the receiving groove 230, avoiding the defect of large impurities directly mixing into the water, thereby improving the blockage of the water-using equipment and maintaining the stable operation of the equipment.

[0032] In some embodiments, see Figure 1 and Figure 2 The outer frame 100 is provided with a first hanging hole 111, and the grid 210 is provided with a second hanging hole 213a at the top. The first hanging hole 111 is located above the second hanging hole 213a. The first hanging hole 111 and the second hanging hole 213a are used for lifting equipment to realize the vertical movement of the filter assembly 200 without leaving the outer frame 100. For example, a manual hoist can be installed in the first hanging hole 111, and the filter assembly 200 can be lifted through the second hanging hole 213a to remove the filter screen 220.

[0033] In actual use, the best solution is to use a two-layer filter assembly 200 to facilitate switching and cleaning, and to completely prevent the filtered material from entering the circulating water system during the cleaning process.

[0034] In some embodiments, the filter assembly 200 includes at least two receiving grooves 230, such as Figure 5The arrangement of two receiving grooves 230 is shown, at least two receiving grooves 230 are arranged at intervals in the height direction, and one receiving groove 230 is installed near the bottom of the grid 210. By arranging more receiving grooves 230, the probability of impurities falling into the grooves is increased, and the completeness of receiving impurities is improved.

[0035] In some embodiments, the filter 220 is a two-layer separator, including an outermost separator and an inner separator, and the mesh size of the inner separator is smaller than the mesh size of the outermost separator.

[0036] In some embodiments, the filter screen 220 is a stainless steel filter screen 220 to increase the service life of the device.

[0037] It is understandable that structures that may come into contact with water during operation are all made of stainless steel, such as the bottom frame 120 and the vertical frame 130 of the outer frame 100 , and the lower structure of the grid 210 .

[0038] In some embodiments, see Figure 4 The grid 210 includes a bottom beam 211, two side beams 212, a top beam 213 and a reinforced support beam 214. The bottom beam 211 and the top beam 213 are relatively spaced apart. The two ends of the side beam 212 are fixedly connected to the bottom beam 211 and the top beam 213 respectively. The two side beams 212 are spaced apart. The reinforced support beam 214 is fixedly arranged between the two side beams 212 and between the bottom beam 211 and the top beam 213. The reinforced support beam 214 is connected to the filter screen 220 to enhance the stability of the filter screen 220 and to address the defect that the steel filter screen 220 is washed by water all year round, resulting in the weakening of its own toughness strength with the operation cycle.

[0039] In some embodiments, the side beam 212 is made of channel steel to cooperate with the slidable setting of the frame 210 and the guide rail.

[0040] The receiving groove 230 has a length, a width and a depth. In some embodiments, the length of the receiving groove 230 is equal to the length of the bottom beam 211, the width of the receiving groove 230 is controlled within the range of one-fifth to one-tenth of the length of the side beam 212, and the depth of the receiving groove 230 is controlled within the range of one-fifth to one-tenth of the length of the side beam 212.

[0041] In some embodiments, the height of the outer frame 100 is more than twice the height of the grid 210. Figure 1 and Figure 2 During the cleaning process of the filter screen 220, try to lift the filter assembly 200 completely out of the water.

[0042] In summary, the circulating water filtration device of the present application can filter out more than 99% of foreign matter in the circulating water cooling pool, and the water-using equipment will not be easily blocked, thereby improving the stability of the equipment operation; it can also solve the problem of manually cleaning the filter 220, where some large impurities on the filter 220 are flushed along the surface of the filter 220 into the anti-impurity falling groove, thereby ensuring that foreign matter does not flow to the water-using equipment.

[0043] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
