Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a sewage filtering device for a concrete test room. Background Art

[0002] A sewage filtration device is a device used to treat sewage. Its main function is to remove impurities such as solid particles, suspended matter, sediments and organic matter in wastewater through different filtration methods, such as physical, chemical, biological, etc., so that the water quality meets the discharge standards or can be reused. Sewage filtration devices are widely used in various industries. For example, in the field of concrete production, a large amount of sewage is generated during the production process of concrete. It contains a lot of sand and gravel. Direct discharge will cause environmental pollution and waste sand and gravel and a large amount of water. Therefore, the sewage needs to be separated and recycled.

[0003] The traditional concrete sewage filtration devices on the existing market still have some defects when in use. For example, in the actual filtration process, the filter screen is easily clogged by sand and gravel, resulting in a decrease in the subsequent sewage filtration and separation effect. Workers are often required to dredge the filter screen to ensure the continued subsequent sewage filtration. However, when traditional workers dredge the filter screen, it will increase the workload of the workers, and sometimes the machine needs to be stopped for dredging, which greatly reduces the filtration effect. For this reason, we propose a sewage filtration device for a concrete laboratory. Utility Model Content

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] When the sewage filtering device of the concrete test room is used, firstly, the concrete sewage is poured into the top of the No. 1 filter plate through the feeding pipe, and the No. 1 filter plate is used to perform preliminary filtration on the sewage to filter out the larger sand and gravel, and at the same time, the driving motor is started to drive the auger to rotate, thereby moving the larger sand and gravel toward the discharge port, and the larger sand and gravel are discharged through the discharge port for easy recycling. After that, the sewage falls downward to the top of the No. 2 filter plate for re-filtration, and at the same time, the rotation of the auger can drive the driving wheel to rotate, and the driving wheel cooperates with the transmission belt to drive the driven wheel and the rotating rod to rotate, thereby driving the knocking block to rotate, thereby repeatedly knocking the No. 2 filter plate. By providing a sliding rod and a spring, the No. 2 filter plate can have a buffering effect, realize vibration filtration, avoid the No. 2 filter plate from being blocked by sand and gravel, improve the filtering effect, and the filtered sewage falls again. Finally, the impurities in the sewage can be intercepted by the filter net, and the harmful substances in the sewage can be adsorbed by the activated carbon to reduce the pollution degree of the sewage, with better treatment effect. Then the treated sewage is discharged through the discharge pipe. The sealing plate can be disassembled by bolts, so that it can be taken out from the inside of the box, and then the filter net and activated carbon can be cleaned. Through the above structures, the effect of preventing blockage can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
