[0023] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1 - 4As shown in the figure, the utility model provides a sewage discharge device for a cooling tower, which comprises: a sewage discharge pipe 3, one end of the sewage discharge pipe 3 is fixedly connected with a connecting block 4, both sides of the connecting block 4 are fixedly connected with connecting pipes 5, valves 6 are arranged on the outer surfaces of the two connecting pipes 5, and filter components 2 are fixedly connected to the ends of the two connecting pipes 5 far away from the connecting block 4; The filter component 2 includes a filter box 202, a cover plate 201 is hinged to the outer surface of the filter box 202, mounting frames 208 are symmetrically and fixedly connected to the inner surface of the filter box 202, a filter net 209 and an activated carbon adsorption plate 210 are respectively inserted into the inner surfaces of the two mounting frames 208, a connecting block 212 is fixedly connected to the front surface of the cover plate 201, mounting grooves 215 are formed in the outer surfaces of both sides of the connecting block 212, telescopic rods 213 are fixedly connected to the inner walls of one sides of the two mounting grooves 215, clamping blocks 211 are fixedly connected to the ends of the two telescopic rods 213, springs 214 are sleeved on the outer surfaces of the two telescopic rods 213, a U-shaped frame 204 is fixedly connected to the front surface of the filter box 202, clamping grooves 205 are formed in the outer surfaces of both sides of the U-shaped frame 204, the outer surfaces of the two clamping grooves 205 are respectively arranged in a clamping fit with the inner surfaces of the two clamping grooves 205, the outer surface of the connecting block 212 is arranged in a matching manner with the inner surface of the U-shaped frame 204, a drain pipe 203 is fixedly connected to one side outer surface of the filter box 202, a cooling tower 1 is fixedly connected to the top end of the sewage discharge pipe 3, and the sides of the two connecting pipes 5 far away from the connecting block 4 are fixedly connected to the sides of the two filter boxes 202 far away from the drain pipe 203.

[0026] The effect achieved by the entire Embodiment 1 is as follows: Connect the sewage pipe 3 to the sewage outlet of the cooling tower 1. Then, the sewage in the cooling tower 1 will enter the connecting block 4 through the sewage pipe 3. Next, the sewage is diverted into two connecting pipes 5 through the connecting block 4. The sewage is sent into two filter boxes 202 through the two connecting pipes 5. The sewage passes through the internal filter screen 209 to filter out larger impurities in the sewage. The filtered sewage then passes through the subsequent activated carbon adsorption plate 210 to adsorb the organic matter in the sewage. After double filtration of the sewage, it is discharged through the drain pipe 203. When it is necessary to disassemble and maintain the internal filter screen 209 and activated carbon adsorption plate 210, the staff can simultaneously push the two side clamping blocks 211 inward, causing the clamping blocks 211 to move into the installation slots 215, so that the clamping blocks 211 are no longer engaged with the card slots 205. Then, the staff rotates the cover plate 201 by 180 degrees along the hinge through the handle on the cover plate 201, separating the cover plate 201 from the filter box 202, and the filter screen 209 and activated carbon adsorption plate 210 can be quickly taken out from the mounting rack 208 for replacement. The inside of the filter box 202 can also be cleaned. After the cleaning and maintenance are completed, insert the filter screen 209 and activated carbon adsorption plate 210 into the filter box 202 along the mounting rack 208, and then rotate the cover plate 201 to move the connecting block 212 into the U-shaped frame 204. When the connecting block 212 is moving, the U-shaped frame 204 will exert a certain squeezing force on the two clamping blocks 211, causing the two clamping blocks 211 to move into the installation slots 215 and compressing the telescopic rod 213 and the spring 214. After the connecting block 212 completely moves into the U-shaped frame 204, the card slot 205 is aligned with the installation slot 215, so that the clamping block 211 is no longer squeezed. Therefore, under the restoring force of the spring 214 rebounding, the clamping block 211 will be pushed out of the installation slot 215, causing the clamping block 211 to be inserted into the card slot 205, completing the limit fixation of the connecting block 212 and enabling the quick installation of the cover plate 201. With the cooperation of the two sets of filtering components 2, when cleaning one set of filtering components 2, the corresponding valve 6 can be closed, and the other set of filtering components 2 can still continue to operate, reducing the downtime and improving the sewage treatment effect.

[0027] Embodiment 2, as Figures 1 - 4 shown, rubber pads 207 are adhesively connected to the tops of both the filter screen 209 and the activated carbon adsorption plate 210, and a rubber strip 206 is adhesively connected to the top of the filter box 202.

[0028] The effect achieved by the entire Embodiment 2 is that after the cover plate 201 is installed, through the arrangement of the rubber strip 206, it can be squeezed and deformed, so as to fill the gap at the connection between the cover plate 201 and the filter box 202, ensuring the sealing performance of the connection. With the cooperation of the two rubber pads 207, a certain downward extrusion force can be provided to the filter screen 209 and the activated carbon adsorption plate 210, preventing the filter screen 209 and the activated carbon adsorption plate 210 from shaking in the filter box 202.

[0029] Working principle: When it is necessary to disassemble and maintain the internal filter screen 209 and activated carbon adsorption plate 210, the staff can simultaneously push the two side blocks 211 inward, so that the blocks 211 move into the installation grooves 215, and the blocks 211 are no longer engaged with the card slots 205. Then, the staff can rotate the cover plate 201 180 degrees along the hinge through the handle on the cover plate 201, separating the cover plate 201 from the filter box 202, and then the filter screen 209 and the activated carbon adsorption plate 210 can be quickly taken out from the mounting frame 208 for replacement, and the inside of the filter box 202 can also be cleaned. After the cleaning and maintenance are completed, the filter screen 209 and the activated carbon adsorption plate 210 are inserted into the filter box 202 along the mounting frame 208, and then the cover plate 201 is rotated to make the connecting block 212 move into the U-shaped frame 204. When the connecting block 212 is moving, the U-shaped frame 204 will exert a certain extrusion force on the two blocks 211, making the two blocks 211 move into the installation grooves 215 and compressing the telescopic rod 213 and the spring 214. After the connecting block 212 completely moves into the U-shaped frame 204, the card slot 205 is aligned with the installation groove 215, so that the block 211 is no longer squeezed. Therefore, under the restoring force of the spring 214 rebounding, the block 211 will be pushed out of the installation groove 215, and the block 211 will be engaged with the card slot 205 to complete the limit fixation of the connecting block 212, enabling the quick installation of the cover plate 201. After the cover plate 201 is installed, through the arrangement of the rubber strip 206, it can be squeezed and deformed, so as to fill the gap at the connection between the cover plate 201 and the filter box 202, ensuring the sealing performance of the connection. With the cooperation of the two rubber pads 207, a certain downward extrusion force can be provided to the filter screen 209 and the activated carbon adsorption plate 210, preventing the filter screen 209 and the activated carbon adsorption plate 210 from shaking in the filter box 202. And with the cooperation of the two sets of filter components 2, when cleaning a certain set of filter components 2, the corresponding valve 6 can be closed, and the other set of filter components 2 can still continue to operate, reducing the downtime and improving the sewage treatment effect.

[0030] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
