Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to a coated whiteboard paper wastewater recovery and treatment device and process. Background Art

[0002] Coated white board belongs to the category of packaging board. It is a processed board made by coating white coating on the original board and finishing it. It is mainly used for making packaging boxes after single-sided color printing. Among them, the wastewater generated in the pulping and papermaking process includes pulping cooking waste liquid, washing wastewater, bleaching wastewater and paper machine white water. Papermaking wastewater has complex components and poor biodegradability. It is a difficult-to-treat industrial wastewater and is one of the main industrial pollution sources in my country.

[0003] Among them, the most commonly used flocculation biological composite treatment method for coated white paper wastewater is, such as an environmentally friendly coated white paper wastewater recovery and treatment method with publication number CN114835315B; the above-mentioned prior art timely cleans the floccules generated in the recovery pool through the movement of the fishing net, effectively preventing the floccules from adsorbing various components inside the recovery pool, and at the same time, the laterally arranged filter net will not affect the liquid circulation speed inside the recovery pool when not in use. Through the rising action of the fishing net, the floccules collected by the fishing net from the wastewater are centrally collected and processed, which is beneficial to the recovery and reuse of metal ions in the floccules. Through the main cleaning rod and the auxiliary cleaning rod, the net surface of the fishing net is effectively cleaned to avoid clogging of the fishing net, improve the fishing effect of the floccules, and prevent the floccules from being dispersed into the water again when the fishing net returns to the wastewater.

[0004] However, the above-mentioned prior art still has some defects when it comes to the recycling and treatment of coated white paper wastewater: 1. The above-mentioned prior art can collect and treat the flocculants collected from the wastewater by the fishing net through the rising action of the fishing net, which is beneficial to the recycling and reuse of metal examples in the flocculants, but during the movement of the fishing net, there will still be residual flocculants in the dead corner of one side of the fishing net, affecting the cleaning effect.

[0005] 2. The above-mentioned prior art uses the movement of the fishing net to clean the flocculants generated in the recovery pool in time, thereby avoiding the accumulation of excessive flocculants inside the recovery pool. However, during long-term use, the movement of the fishing net will cause wear and tear on the fishing net, affecting the fishing effect, and the fishing net is not easy to replace.

The filter plate 33 is provided with a positioning block 36 corresponding to the positioning groove 35 one by one. The cooperation between the positioning groove 35 and the positioning block 36 is used to position the filter plate 33.

[0043] When the rotating plate 23 rotates, the filter plate 33 facing one end of the loading rack 14 moves upward around the rotating shaft 22 to capture and filter the flocculants in the wastewater.

[0044] refer to Figure 4 , is a schematic diagram of the structure of the fixing element 4 of the present invention. In order to install the filter plate 33 in the installation groove 32 and facilitate the removal and installation of the filter plate 33 when replacing the filter plate 33, the filter device 3 also includes a fixing element 4 arranged on the installation bar 31. The fixing element 4 includes a transmission bar 41 slidably installed inside the installation bar 31. The end of the transmission bar 41 facing the rotating shaft 22 is provided with a connecting spring 42 connected to the installation bar 31. The connecting spring 42 enables the transmission bar 41 to slide and reset toward the side of the connecting spring 42. The positioning grooves 35 are each provided with a sliding hole 43. A positioning block 44 is slidably provided in the sliding hole 43, which is used to clamp the positioning block 36 to limit the upward and downward movement of the filter plate 33, and the positioning block 44 is used to clamp the positioning block 36 to limit the upward and downward movement of the filter plate 33. The end of the block 44 facing the filter plate 33 is tilted downward to facilitate the installation of the filter plate 33. A connecting hole 45 is provided in the positioning block 44, and the transmission bar 41 passes through the connecting hole 45. The end of the positioning block 44 facing away from the filter plate 33 is connected to the mounting bar 31 through a return spring 46. The return spring 46 causes the positioning block 44 to slide toward the return spring 46 and return to its original position. A plurality of transmission blocks 47 are provided on the side of the transmission bar 41 facing away from the filter plate 33, and each transmission block 47 is respectively located at one end of each positioning block 44 facing the rotating shaft 22. When the mounting bar 31 is pulled, the transmission block 47 causes the positioning block 44 to slide in the direction of the return spring 46 to release the restriction of the positioning block 44 on the positioning block 36.

[0045] When removing the filter plate 33, the transmission bar 41 slides together in the direction away from the rotating shaft 22, stretching the connecting spring 42, and the transmission block 47 slides the blocking block 44 in the direction of the return spring 46, compressing the return spring 46, and the blocking block 44 releases the restriction on the positioning block 36, and the filter plate 33 can be taken out.
