Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment in base paper production, and in particular to a wastewater treatment device in base paper production. Background Art

[0002] Papermaking wastewater refers to wastewater generated during the pulping and papermaking process; it includes pulping cooking wastewater, washing wastewater, bleaching wastewater and paper machine white water, etc. The main pollutants contained therein include suspended solids, that is, settleable suspended solids and non-settled suspended solids. For example, the wastewater discharged from the original pulp after the pulper is difficult to recover due to the small amount of organic matter (fiber and alkali, etc.) contained in it, but the total solids, suspended solids and BOD5 in the wastewater are still very high, and direct discharge still causes serious water pollution. The main treatment methods include coagulation and sedimentation, flotation and activated sludge method, etc.; among them, flotation refers to the use of highly dispersed tiny bubbles as carriers to adhere to pollutants in the wastewater, making their buoyancy greater than gravity and floating resistance, so that the pollutants float to the water surface to form foam, and then use scraping equipment to scrape the foam from the water surface.

[0003] In the existing paper production wastewater treatment by flotation method, a rotating scraper plate or a scraper plate that reciprocates back and forth is mostly used to scrape the floating objects in the wastewater, so that the floating garbage is concentrated together and treated by manual salvage. This treatment is time-consuming and labor-intensive, and increases the workload of operators moving around the treatment pool. The scraper plate with a flat structure cannot completely scrape the horizontal floating objects, and the salvage efficiency is relatively low. The scraper plate cannot be cleaned during the salvage process, resulting in the residual garbage on the scraper plate entering the wastewater treatment pool again, reducing the sewage treatment efficiency. In addition, some methods are to disassemble and clean the scraper plate, but disassembly and assembly are difficult, and more time-consuming and labor-intensive. Summary of the invention

The bottom ends of the support plate 42 are connected to a collecting plate 44 through a rotating seat 43. The top centers of both sides of the interior of the arc-shaped collecting cover 2 are fixedly installed on the two ends of the collecting plate 44 by bolts.

The through connection has a simple and stable structure.

[0044] See also Figure 1 , Figure 3 and Fig.10 The adjusting rod 31 is an inclined structure, and the adjusting rod 31 is movable through the adjusting groove 37 opened at the center of one side of the adjusting frame 3, and the adjusting block 34 is movable through the adjusting limit rods 38 at two points inside the adjusting frame 3. An annular groove 16 is opened at the top center of the wastewater treatment tank 1, and a support rod 45 is fixedly installed at the bottom center of the other end of the U-shaped fixing plate 4 by bolts. The bottom end of the support rod 45 is fixedly installed with a rolling wheel 17 that moves in the annular groove 16 by bolts. The rolling wheel 17 is used to make the arc-shaped collection cover 2 rotate stably and smoothly on the wastewater treatment tank 1. A plurality of collecting holes 25 are evenly opened on the arc-shaped collection cover 2 to filter suspended matter. A rotating seat 43 is connected between the bottom center of the adjusting frame 3 and the collecting plate 44, and the cleaning frame 5 is installed on the U-shaped fixing plate 4 on the side away from the fixing seat 21 to achieve the angle adjustment of the arc-shaped collection cover 2.

[0045] See also Figure 1 , Figure 2 and Figure 5 , a plurality of telescopic springs 24 are evenly installed in the fixing holes 22 on the fixing seat 21 near the side of the adjusting frame 3, and the top of the telescopic spring 24 is fixedly installed on the bottom end of the U-shaped fixing buckle 23. The telescopic spring 24 is used to open the U-shaped fixing buckle 23 back and forth, which is convenient for fixing and disassembling the adjusting ring 33 under the hinged rod 32. The operation is simple, and both ends of the bottom of the U-shaped fixing buckle 23 are movable in the fixing holes 22. The cleaning storage tray 15 is movable on one side of the bottom of the arc-shaped collecting cover 2, and the L-shaped connecting rod 14 is installed at the center of one end of the cleaning storage tray 15. A sewage pipe 18 is opened at the bottom of one end of the cleaning storage tray 15 away from the L-shaped connecting rod 14, so that the collected suspended garbage is concentratedly flushed away. The operation is convenient and simple, and the efficiency of wastewater cleaning is improved.

[0046] Working principle: A conduit capable of generating high-density bubbles is placed at the bottom of the wastewater treatment pool 1. The bubbles are light in density and easily adhere to the suspended matter in the wastewater from base paper production, so that the suspended matter floats to the water surface. In addition, an active agent can be added to make the attachment of bubbles to the suspended matter more stable. This is an existing means of wastewater treatment and is not described in detail in this article. By driving the motor 62, the first gear 63 and the second gear 64, the rotating column 12 in the fixed cylinder 11 drives the arc-shaped collection cover 2 under the U-shaped fixed plate 4 to rotate on the water surface, thereby achieving stable collection of suspended matter.

[0047] Before use, the thickness of the suspended matter on the water surface is judged, and the adjusting block 34 on the adjusting screw 36 is driven up and down by the first motor 35 in the adjusting frame 3. The adjusting block 34 tilts the rotating seat 43 connected to the arc-shaped collecting cover 2 at a certain angle through the adjusting rod 31, the hinge rod 32, the adjusting ring 33 and the U-shaped fixing buckle 23, so that the angle at which the arc-shaped collecting cover 2 enters the water surface satisfies the collection of suspended matter of different thicknesses, and the collection is thorough.

[0048] After the arc-shaped collecting hood 2 is full of suspended garbage, the hydraulic telescopic pump 41 is used to lift the arc-shaped collecting hood 2, and the cleaning collection tray 15 outside the rotating column 12 reaches the bottom center of the arc-shaped collecting hood 2. The adjusting block 34 is continuously used to drive the arc-shaped collecting hood 2 to tilt, so that the garbage on the arc-shaped collecting hood 2 is dumped into the cleaning collection tray 15 for centralized treatment. The operation is simple. After that, the spray head 52 is connected to the water pipe through the wedge-shaped connecting block 51 to achieve thorough cleaning of the arc-shaped collecting hood 2, and the cleaning effect is good.

[0049] During cleaning, the adjusting block 34 can drive the arc-shaped collecting cover 2 to reciprocate back and forth under the rotating seat 43, thereby achieving a thorough cleaning effect.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
