[0002] Building wastewater refers to wastewater generated in the process of construction engineering construction, building material production, building decoration and building maintenance, etc. Its composition is complex, and if it is directly discharged without treatment, it will cause serious pollution to the environment.

[0003] The chemical wastewater filtration equipment disclosed in the publication No. CN209475759U includes a filter cylinder, a water inlet, a water outlet, a filter layer, a filter plate and a fan blade. The water inlet is arranged at the top of the filter cylinder, and the water outlet is arranged at the bottom surface of the filter cylinder. A motor is arranged below the filter cylinder, and the motor is connected to the fan blade in the filter cylinder through a rotating shaft. The filter layer is a reverse conical shape arranged at the lower end of the water inlet, and the upper edge of the reverse conical shape is connected to the surrounding filter cylinder wall. The fan blade is arranged at the bottom of the filter cylinder, and a plurality of filter plates are arranged between the fan blade and the filter layer. The present application increases the filter area, so that the device can more fully treat wastewater. The filter plates are distributed with filter holes, which increase the contact area between harmful substances in wastewater and filter paper, so that the filtration is more sufficient.

[0004] In the prior art, the filter area is increased to make the treatment of wastewater more sufficient. However, when wastewater is filtered, the pollutants in the wastewater will be intercepted by the filter plate, thereby accumulating on the filter plate, causing blockage in some places of the filter plate.

At the same time, due to the blockage of the filter plate, wastewater is also difficult to discharge, cannot realize backwashing, and causes the internal pressure to increase, thereby damaging the internal filtration equipment.

[0029] The working principle of the present application is as follows: firstly, a filter tube 28 with a proper mesh number is selected according to the filtering process, and then the filter tube 28 is inserted into the fixing frame, when being inserted, the clamping column 281 on the side wall of the filter tube 28 is aligned with the L-shaped groove 251 in the fixing frame, then the filter tube 28 is rotated to make the clamping column 281 clamped with the L-shaped groove 251, so as to realize the installation of the filter tube 28, after the installation is completed, the water delivery pipe 18 is opened, so that the construction waste water in the filter bin 11 is delivered to the inside of the backwashing bin 21 through the water delivery pipe 18, wherein the water delivery pipe 18 is arranged below the fixed plate 22, the waste water first reaches below the fixed plate 22, then the waste water input by the water delivery pipe 18 will enter the filter tube 28 through the water hole 221, and then the impurities will be intercepted in the filter tube 28, and the filtered water will be discharged from the water outlet pipe 6 through the filter tube 28, so as to complete the filtering work, when filtering, the backwashing pipe 23 at the bottom of the backwashing bin 21 is driven to rotate, and when rotating, the waste guide pipe 231 will be aligned with the water hole 221, wherein the axial distance between the water hole 221 and the center of the fixed plate 22 is consistent with the axial distance between the waste guide pipe 231 and the center of the fixed plate 22, when the waste guide pipe 231 is driven to rotate, it will be aligned below the water hole 221, so as to close a group of filter tubes 28, after being closed, the waste discharge pipe 24 is started to suck out the waste water in the filter tube 28, in the process of sucking out, the impurities in the filter tube 28 will be sucked into the waste guide pipe 231 together, and then discharged from the waste discharge pipe 24, so as to achieve the effect of backwashing, after a group of filter tubes 28 are sucked out, the backwashing pipe 23 is driven to rotate again, and the waste guide pipe 231 is driven to the next group of water holes 221 below, so as to backwash another group of filter tubes 28, when the filtering work is carried out, through the continuous rotation of the backwashing pipe 23, a plurality of filter tubes 28 can be continuously backwashed, so as to avoid that the impurities in the construction waste water block the filter tube 28, so as to cause pressure imbalance and damage to the internal mechanism of the backwashing bin 21, at the same time, through the arrangement of the waste guide pipe 231, the backwashing bin 21 does not need to be stopped, and the backwashing can be carried out at the same time of filtering, so as to improve the filtering effect, at the same time, through the arrangement of the mounting frame 25, the installation of filter tubes 28 with different mesh numbers can be realized, and through the arrangement of the L-shaped groove 251, the filter tube 28 can be fixed.

[0030] Wherein, when the backwash pipe 23 is driven to rotate, the backwash pipe 23 drives the gear plate 232 to rotate, thereby driving the gear I 223 to rotate by the gear plate 232, when the gear I 223 rotates, the driven column 222 and the gear II 224 above are driven to rotate, thereby driving the driven gear 272 to rotate, when the driven gear 272 rotates, the rotating column 27 and the beating plate 271 are driven to rotate, when the beating plate 271 rotates, the end of the beating plate 271 will contact the push block 263 on the side of the vibration striking bin 26, after the contact, with the rotation of the beating plate 271, the push block 263 is pushed backward, when moving, the push block 263 and the vibration striking block 262 extrude the vibration striking spring 261, when the beating plate 271 rotates to a certain angle, the beating plate 271 will be separated from the push block 263, after the separation, the push block 263 and the vibration striking block 262 lose the backward force, then the vibration striking spring 261 rebounds, which quickly drives the vibration striking block 262 to impact the side wall of the filter pipe 28, when the impact, the impurities stuck on the inner wall of the filter pipe 28 are shaken off, avoiding the blockage, and the beating plate 271 and the vibration striking block 262 are arranged in multiple groups, extending from the bottom of the fixed frame to the top of the filter pipe 28, and each group of fixed frame is provided with a vibration striking bin 26, facilitating the cleaning of the filter pipe 28, through the arrangement of the vibration striking bin 26 and the beating plate 271, in the backwashing process, the impurities in the filter pipe 28 can be backwashed by cooperating with the waste guide pipe 231, avoiding the problem that the impurities are adhered to the inner wall of the filter pipe 28, causing subsequent blockage, and through the arrangement of the gear I 223 and the gear II 224, the beating plate 271 can be driven to work when the backwash pipe 23 rotates, realizing continuous cleaning, so that the impurities in the filter pipe 28 are shaken out and float in the filter pipe 28 before the waste guide pipe 231 is connected with the water hole 221, and the waste guide pipe 231 does not need to stay under the water hole 221 for too long.

[0031] The above describes one embodiment of the present application in detail, but the content is only the preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the patent coverage of the present application.
