Description

Technical Field

[0001] This utility model relates to the technical field of papermaking wastewater recycling, and in particular to a papermaking wastewater recycling device. Background Technology

[0002] The pretreatment process for papermaking wastewater mainly consists of processes such as bar screens, sieves, fiber recovery systems, and water volume and quality regulation. Different pretreatment methods can be adopted according to the different wastewater qualities of the papermaking industry to remove some pollutants, improve the wastewater quality, and achieve the best treatment effect of the entire wastewater treatment system.

[0003] A search of Chinese Patent Publication No. CN221319427U reveals a waste paper recycling and papermaking wastewater recovery device, comprising a filter shell with a filter pool inside for filtering papermaking wastewater. A drive motor is fixedly mounted on the left side of the filter shell, and a rotating shaft is fixedly connected to the right side of the drive motor, with the rotating shaft located in the filter pool of the filter shell. This waste paper recycling and papermaking wastewater recovery device filters pulp impurities from the wastewater through a filter screen, achieving pulp impurity filtration. Simultaneously, a rotating cleaning scraper removes pulp impurities from the surface of the filter screen, thus facilitating wastewater filtration. Furthermore, the outer end of the cleaning rod collides with the vibrating blocks on the inner wall of the vibrating ring, causing the cleaning scraper to vibrate, thereby enhancing the removal of pulp impurities from the filter screen surface and further improving its applicability.

[0004] However, although the aforementioned waste paper recycling and papermaking wastewater recovery device can solve the problems of filter clogging and impurity removal to a certain extent, it is difficult to collect impurities inside the recycling and processing tank. This leads to the gradual accumulation of impurities inside the tank. Over time, the accumulated impurities will occupy the internal space of the tank, reducing the effective volume of wastewater and thus affecting the efficiency of wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to provide a papermaking wastewater recycling device to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A papermaking wastewater recycling device includes:

[0008] Recycle components;

[0009] The recycling component includes: a processing box; a connecting frame, fixedly connected to the lower end of one side of the processing box, and the connecting frame communicating with the interior of the processing box; and a collection component, the collection component including:

[0010] The mounting slot is located in the middle of one side of the connecting frame;

[0011] Fixing blocks are fixed at the four corners of the mounting slot;

[0012] The slot is located in the middle of one side of the fixing block;

[0013] The filter frame slides into the mounting slot;

[0014] The first filter hole has a filter frame on one side;

[0015] The second filter hole is located on the other side of the filter frame, and the second filter hole is larger than the first filter hole.

[0016] Optionally, a first motor is fixed to one side of the processing box, and a rotating rod is fixedly connected to the output end of the first motor, and the rotating rod is rotatably installed inside the processing box.

[0017] Optionally, a stirring fan is fixed to the outer surface of the rotating rod, and a water outlet pipe is fixedly connected to one side of the connecting frame, with the water outlet pipe communicating with the connecting frame.

[0018] Optionally, a sealing plate is fixed to one side of the filter frame. The sealing plate is cross-shaped and has fixing holes.

[0019] Optionally, a spring is fixed inside the fixing hole, and a locking pin is fixed to one end of the spring.

[0020] Optionally, the locking pin is aligned with the locking slot, and the end of the locking pin extends into the slot.

[0021] Optionally, a dosing assembly is also included; the dosing assembly includes: a fixed plate, fixed to both sides of the top surface of the treatment box; a second motor, fixed to one side of the fixed plate; a lead screw, fixed to the output end of the second motor, and the lead screw passes through both fixed plates; and a movable block, threaded through the outer surface of the lead screw.

[0022] Optionally, a limiting post is fixed inside the fixed plate, and the movable block slides through the limiting post. An installation hole is provided on one side of the movable block, and a dosing tank is fixed inside the installation hole.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] By using a recycling and collection component, when papermaking wastewater is in the treatment tank, it flows out of the outlet pipe through the connecting frame. The wastewater then passes through the filter frame, entering through the second filter hole and exiting through the first filter hole. Because the diameter of the second filter hole is smaller than that of the first filter hole, impurities in the wastewater flow into the filter frame through the second filter hole and cannot flow out through the first filter hole, thus remaining inside the filter frame. When the filter frame is full of impurities, the locking post is pressed inward through the locking slot, compressing the spring in the fixing hole and causing the locking post to exit from the locking slot. The sealing plate and filter frame are then removed from the mounting slot, and the impurities inside the filter frame are cleaned. When papermaking wastewater flows into the connecting frame and then into the filter frame, impurities first enter the filter frame through the second filter hole and cannot flow out through the first filter hole, allowing for rapid collection of impurities inside the filter frame. This centralized collection of impurities facilitates subsequent unified treatment, improves the efficiency of impurity collection, and solves the problems in the existing technology.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Given the current technology, although the aforementioned waste paper recycling and papermaking wastewater recovery device can solve the problems of filter clogging and impurity scraping to a certain extent, it is difficult to collect impurities inside the recycling and processing tank. This leads to the gradual accumulation of impurities inside the processing tank. Over time, the accumulated impurities will occupy the internal space of the processing tank, reducing the effective volume of wastewater in the processing tank, and thus affecting the efficiency of wastewater treatment.

[0037] like Figure 1-3 As shown, this utility model embodiment provides a papermaking wastewater recycling device, including:

[0038] Recycle component 1;

[0039] The recycling component 1 includes: a processing box 11; a connecting frame 15, fixedly connected to the lower end of one side of the processing box 11, and the connecting frame 15 communicating with the interior of the processing box 11; and a collection component 2, which includes:

[0040] Mounting slot 21 is provided in the middle of one side of the connecting frame 15;

[0041] Fixing blocks 22 are fixed at the four corners of the mounting slots 21;

[0042] The card slot 221 is located in the middle of one side of the fixing block 22;

[0043] The filter frame 23 is slidably placed inside the mounting slot 21;

[0044] The first filter hole 231 is located on one side where the filter frame 23 is installed;

[0045] The second filter hole 232 is located on the other side of the filter frame 23, and the second filter hole 232 is larger than the first filter hole 231.

[0046] Among them, the treatment box 11 serves as the main container for wastewater treatment, providing a centralized treatment space for wastewater. The connecting frame 15 provides an installation position for the collection component 2, and the installation slot 21 provides an accurate installation position for the filter frame 23, ensuring the stability and accuracy of the filtration process. The slot 221 works in conjunction with the locking post 27 to enable the quick installation and disassembly of the filter frame 23. The filter frame 23 is a key component for intercepting impurities in wastewater. It has a first filter hole 231 and a second filter hole 232 on both sides. Through the clever setting of the size of the holes, it can effectively filter impurities in wastewater in stages.

[0047] A first motor 12 is fixed on one side of the processing box 11. A rotating rod 13 is fixedly connected to the output end of the first motor 12. The rotating rod 13 is rotatably installed inside the processing box 11. A stirring fan 14 is fixed on the outer surface of the rotating rod 13. A water outlet pipe 16 is fixedly connected to one side of the connecting frame 15. The water outlet pipe 16 and the connecting frame 15 are interconnected.

[0048] The outlet pipe 16 is connected to the connecting frame 15. Its main function is to discharge the pre-treated wastewater from the treatment tank 11 and send it to the subsequent treatment stage or storage device. The stirring fan 14 will uniformly stir the wastewater into which the reagent is added.

[0049] A sealing plate 24 is fixed on one side of the filter frame 23. The sealing plate 24 is cross-shaped and has a fixing hole 25. A spring 26 is fixed inside the fixing hole 25. A locking post 27 is fixed at one end of the spring 26. The locking post 27 is directly opposite to the locking groove 221, and the end of the locking post 27 extends into the locking groove 221.

[0050] The sealing plate 24 is cross-shaped, and its main function is to ensure a good seal at the connection between the filter frame 23 and the treatment box 11. The fixing hole 25 serves as the installation interface for components such as the spring 26 and the locking post 27, providing accurate installation positions for these components. The main function of the spring 26 is to provide an elastic connection. The locking post 27 corresponds to the locking groove 221, and its end extends into the inside of the locking groove 221. Its main function is to firmly lock the filter frame 23 onto the treatment box 11, preventing the filter frame 23 from shifting or falling off during use.

[0051] In use, when papermaking wastewater is in the treatment tank 11, it flows out of the outlet pipe 16 through the connecting frame 15. The wastewater passes through the filter frame 23 via the connecting frame 15. The wastewater enters through the second filter hole 232 of the filter frame 23 and then flows out through the first filter hole 231. Because the diameter of the second filter hole 232 is smaller than that of the first filter hole 231, impurities in the wastewater will flow into the filter frame 23 through the second filter hole 232, and the impurities cannot flow out through the first filter hole 231, so the impurities will remain in the filter frame 23. When the filter frame 23 is full of impurities, the locking post 27 is pressed towards the center through the locking groove 221. This compresses the spring 26 into the fixing hole 25, causing the locking pin 27 to exit from the locking groove 221. The sealing plate 24 and the filter frame 23 are then removed from the mounting groove 21. The impurities inside the filter frame 23 are then removed. When papermaking wastewater flows into the connecting frame 15 and then into the filter frame 23, the impurities will first enter the filter frame 23 through the second filter hole 232. The impurities cannot flow out from the first filter hole 231 and can remain inside the filter frame 23. This allows the impurities to be quickly collected inside the filter frame 23, facilitating subsequent unified processing and improving the efficiency of impurity collection.

[0052] Specifically, such as Figure 1-4 As shown,

[0053] The dosing assembly 3 includes: a fixed plate 31, fixed on both sides of the top surface of the treatment box 11; a second motor 32, fixed on one side of the fixed plate 31; a lead screw 33, fixed at the output end of the second motor 32, and the lead screw 33 passes through both fixed plates 31; and a movable block 35, threaded through the outer surface of the lead screw 33.

[0054] The fixed plate 31 has a limiting post 34 fixed inside, and the movable block 35 slides through the limiting post 34. A mounting hole 351 is opened on one side of the movable block 35, and a dosing tank 36 is fixed inside the mounting hole 351.

[0055] Among them, the fixed plate 31 serves as the basic structure of the dosing assembly 3, providing a stable support frame for the entire dosing system. The second motor 32 is the power source of the dosing assembly 3. It is connected to the lead screw 33 through the output end, providing power for the rotation of the lead screw 33. The lead screw 33 converts the rotational motion of the second motor 32 into the linear motion of the movable block 35. The movable block 35 slides through the surface of the limiting post 34 and the lead screw 33, and the movable block 35 drives the dosing tank 36 to reciprocate horizontally.

[0056] In use, chemicals are added inside the treatment tank 11. The first motor 12 drives the rotating rod 13 to rotate, which in turn drives the stirring fan 14 to rotate. Chemicals are then added into the dosing tank 36. Next, the second motor 32 drives the lead screw 33 to rotate, which in turn drives the movable block 35 to move horizontally. The limiting post 34 limits the movement of the movable block 35. The movable block 35 drives the dosing tank 36 to move horizontally, and the dosing tank 36 evenly adds chemicals into the treatment tank 11. This helps ensure that every part of the wastewater comes into contact with an appropriate amount of chemicals, thereby improving the treatment effect.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
