[0002] Papermaking wastewater refers to the wastewater generated during the pulping and papermaking process, including pulping and cooking waste liquor, washing wastewater, bleaching wastewater, and machine washing white water. Papermaking wastewater has a complex composition and poor biodegradability, making it a relatively difficult industrial wastewater to treat. It generally contains large amounts of suspended solids, BOD, COD, and some toxic substances, and is typically treated using a combination of physical and biological methods.

[0003] In existing technologies, the biochemical treatment of papermaking wastewater often requires the addition of agents such as flocculants to allow for a full biochemical reaction before it can proceed to the next treatment step. The addition of these agents is often done in a fixed manner, which can easily lead to uneven distribution of the agents in the wastewater, thus affecting the treatment effect on papermaking wastewater and consequently impacting subsequent treatment processes.

Detailed Implementation

[0026] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0027] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] Please refer to Figures 1-8 ,

[0029] This invention provides a papermaking wastewater treatment device. In the prior art, papermaking wastewater often requires the addition of chemicals for treatment. However, the addition of chemicals is often done in a fixed manner. This method of addition can easily lead to uneven distribution of chemicals in the wastewater, thereby affecting the treatment effect of papermaking wastewater and subsequently affecting subsequent treatment processes. In order to solve the above-mentioned technical problems, this invention optimizes the treatment equipment to improve the mixing efficiency of chemicals and wastewater.

[0030] As shown in the figure, the system includes a dosing treatment tank 100 and a filter box. The dosing treatment tank 100 includes a dosing assembly 200 and a stirrer 300. The structure of the dosing assembly 200 will now be described in detail. The dosing assembly 200 mainly includes a sliding member 210. The top of the sliding member 210 has a strip-shaped groove 211, and a sliding column 212 is slidably embedded in the groove 211. The top of the sliding column 212 is provided with a rocker arm 213, which is perpendicular to the axis of the sliding column 212. The free end of the rocker arm 213 is fixedly sleeved on the outside of the rotating shaft 214. The power of the rotating shaft 214 comes from the drive motor 215. The drive motor 215 causes the rotating shaft 214 to make a circular motion, which in turn drives the rocker arm 213 to make a circular motion around the rotating shaft 214. In order to facilitate the installation of the drive motor 215, an mounting plate 120 is also provided in the middle of the top of the dosing treatment tank 100, and the drive motor 215 is installed in the mounting plate 120.

[0031] In order to enable the sliding member 210 to reciprocate within the dosing treatment tank 100, slide rails 110 are provided on the top of both sides of the dosing treatment tank 100. The two ends of the sliding member 210 are placed in the slide rails 110. During the circular motion of the swing rod 213, the sliding member 210 is driven to reciprocate linearly. Preferably, the dosing treatment tank 100 has a square structure and its slide rails 110 are set on the inner sidewall of the opposite side.

[0032] A medicine storage box 220 is also provided at the bottom of the sliding member 210. The medicine storage box 220 can be fixedly installed at the bottom of the sliding member 210 by bolts or other structures. Several leakage holes 222 are opened at the bottom of the medicine storage box 220. When the sliding member 210 makes reciprocating linear motion, the medicine in the medicine storage box 220 is driven to leak out from the leakage holes 222 and follow the reciprocating motion, thereby evenly spreading the medicine into the bottom dosing treatment tank 100. The bottom of the rotating shaft 214 extends towards the bottom of the dosing treatment tank 100, and a stirrer 300 is provided near the bottom of the rotating shaft 214. The stirrer 300 is composed of multiple stirring blades. While the rotating shaft 214 drives the medicine storage box 220 to evenly spread the medicine into the dosing treatment tank 100, it also drives the stirrer 300 to stir and mix the medicine and wastewater in the dosing treatment tank 100 evenly, thereby improving the efficiency of uniform mixing.

[0033] The structure of the medicine storage box 220 is shown in the figure: it mainly includes a box body 221, a medicine injection hole 224 is provided on the top side of the box body 221, a leakage hole 222 is provided on the bottom of the box body 221, and the side of the box body 221 extends upward and has an installation hole 223, so that it can be fixedly connected to the side of the sliding member 210 by bolts.

[0034] After removing the bolts, the aforementioned medicine storage box 220 can also be removed from the bottom of the sliding member 210. After removal, new medicine is added through the injection hole 224, and then it is reinstalled into the bottom of the sliding member 210. In addition to the above-mentioned method of adding medicine, this utility model also provides another method of adding medicine, namely, installing a medicine tank 130 on the outer wall of the dosing treatment pool 100, and setting the injection hole 224 of the medicine storage box 220 on the side top of the box body 221. A connecting pipe is set between the box body 221 and the medicine tank 130. This connecting pipe is selected as a telescopic pipe (which can be a corrugated pipe). During the reciprocating movement of the sliding member 210, it does not affect its normal connection relationship. An infusion pump is also set in the connection between the box body 221 and the medicine tank 130 to input the medicine into the medicine storage box 220. The advantage of this setting is that it can avoid repeated disassembly and assembly of the medicine storage box 220, reduce processing steps, and improve efficiency.

[0035] The workflow of this utility model is as follows:

[0036] Papermaking wastewater is injected into the dosing treatment tank 100. Chemical solution is supplied to the storage box 200 via the chemical tank 130. This chemical solution can be a conventional wastewater treatment chemical, which is existing technology and will not be elaborated upon here. The rotation of the drive motor 215 causes the swing arm 213 to rotate around the rotating shaft 214 in a circular motion, which in turn causes the sliding member 210 to reciprocate linearly within the slide rail 110. The storage box 220 at the bottom of the sliding member 210 also reciprocates linearly. The chemical solution is evenly sprayed into the dosing treatment tank 100 through the leakage hole 222 and stirred by the stirring blades at the bottom of the rotating shaft 214 to achieve uniform mixing, thereby improving the wastewater treatment efficiency. The treated wastewater still needs further purification processes until it meets discharge requirements before being discharged. These subsequent treatment processes can be conventional and will not be elaborated upon here.

[0037] This device uses a drive motor 215 to drive the sliding component 210 to perform reciprocating linear motion, thereby achieving the purpose of uniformly dispensing the medicine. At the same time, it also drives the stirring blades at the bottom of the rotating shaft 214 to stir the wastewater and medicine, thereby achieving uniform mixing and improving the treatment efficiency. The design of this device is ingenious, which can effectively improve efficiency and reduce production costs.

[0038] To further optimize this device, a filter tank 500 is also provided. The filter tank 500 is located above the dosing treatment tank 100, specifically through the installation frame 400. A filter screen 510 is installed in the filter tank 500 to filter out some large pieces of waste fiber and other materials in the papermaking wastewater, which is more conducive to the subsequent treatment effect after dosing. The filtered wastewater is discharged into the dosing treatment tank 100 through the connecting pipe 520.

[0039] To improve the filtration effect, a swing assembly 530 is also installed inside the filter tank 500. This swing assembly 530 includes a connecting plate 531 located at the top of the filter tank 500, as shown in the figure. It also includes a connecting rod 532 connected to the filter screen 510. The bottom of the connecting rod 532 is directly connected to the filter screen 510, and the other end of the connecting rod 532 extends towards the connecting plate 531. A rotary motor 533 is also installed at the top of the connecting plate 531, and a through hole 536 is formed in the connecting plate 531. A crank handle is installed on the output shaft of the rotary motor 533. 534, the crank 534 can make circular motion under the action of the rotating motor 533. The end of the crank 534 is hinged to the rocker arm 535. The free end of the rocker arm 535 is hinged to the top of the filter screen 510. In addition, a movable groove 5001 is provided in the inner wall of the filter tank 500. The side of the filter screen 510 is set in the movable groove 5001. Driven by the rotating motor 533, the rocker arm 213 can lift the filter screen 510 below to make reciprocating linear motion in the movable groove 5001, thereby playing a certain role in up-and-down moving oscillation filtration.

[0040] The filter tank 500 provided by this utility model can perform preliminary treatment of papermaking wastewater, reduce the impact of large impurities on subsequent chemical treatment of wastewater, and at the same time improve the efficiency of wastewater treatment.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
