Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Specific implementation examples are given below.
[0020] like Figures 1 to 3 As shown in the embodiment of this utility model, a papermaking wastewater pretreatment device includes a filter tank 1. An inlet 11 is fixedly connected to the inside of the filter tank 1. A filter disc 12 is fixedly connected to the inner wall of the filter tank 1. A fixing seat 13 is fixedly connected to the bottom end of the filter disc 12. A collection cylinder 14 is fixedly connected to the lower surface of the fixing seat 13. A filter cylinder 15 is provided on the outer wall of the collection cylinder 14. A fixing block 16 is fixedly connected to the outer wall of the filter cylinder 15. Fixing holes 101 are provided inside both the fixing seat 13 and the fixing block 16. A fixing shaft 102 is provided on the inner wall of the fixing hole 101. During operation, wastewater is added into the filter tank 1 through the inlet 11. The wastewater flows and accumulates on the surface of the filter disc 12, and then, under the action of gravity, passes through the collection cylinder 14 and the filter cylinder 15 and precipitates outwards. The filtered residue and particles accumulate. Inside the collection cylinder 14, to facilitate subsequent absorption and transfer, the filter cylinder 15 can be disassembled and replaced when it is saturated. The filter cylinder 15 is quickly fixed by the cooperation of the fixing hole 101 and the fixing shaft 102. The fixing seat 13 and the fixing block 16 support and fix the filter cylinder 15. Through the above structure, the function of filtering wastewater is realized by the cooperation of the collection cylinder 14 and the filter cylinder 15. The impurities filtered out of the wastewater will accumulate inside the collection cylinder 14, which facilitates subsequent cleaning and transfer. At the same time, the cooperation of the fixing hole 101 and the fixing shaft 102 realizes the function of quickly fixing the filter cylinder 15, which facilitates the disassembly of the filter cylinder 15, optimizes the replacement steps, reduces downtime, and improves the stability and convenience of the device during use.
[0021] like Figure 1 and Figure 5 As shown, a second motor 4 is fixedly connected to the top of the filter tank 1. A lead screw 41 is fixedly connected to the output end of the second motor 4. A lifting block 42 is threadedly connected to the outer wall of the lead screw 41. A drain pipe 43 is fixedly connected to the outer wall of the lifting block 42. A drain pump 44 is fixedly connected to the top of the drain pipe 43. A fixed cylinder 45 is fixedly connected to the top of the filter tank 1. A limiting groove 401 is opened inside the fixed cylinder 45. The outer wall of the drain pipe 43 is slidably connected to the inner wall of the fixed cylinder 45, and the outer wall of the lifting block 42 is slidably connected to the inner wall of the limiting groove 401. During operation, when it is necessary to transfer the impurities accumulated inside the filter tank 1, the operator can start the second motor 4. The start of the second motor 4 drives the lead screw 41 to rotate. The rotation of the lead screw 41 drives the lifting block 42 threadedly connected to its outer wall to move up and down. When the lifting block 42 moves, it drives the drain pipe 43 to move downward. After moving a certain distance, the device comes into contact with impurities. At this point, the sewage pump 44 is activated, drawing out the impurities and creating an environment for subsequent filtration operations. The fixed cylinder 45 supports and fixes the sewage pipe 43, while the limiting groove 401 limits the movement of the lifting block 42. Through the above structure, the second motor 4 and the lead screw 41 work together to adjust the position of the lifting block 42 up and down, allowing the lifting block 42 to be flexibly adjusted to different heights according to the progress of impurity cleaning. Compared with traditional manual cleaning methods, this device has higher flexibility and convenience in use, reducing the intensity of manual labor. At the same time, the limiting groove 401 limits the movement of the lifting block 42, ensuring that the sewage pipe 43 maintains a fixed movement path and angle, improving the stability during operation.
[0022] like Figure 2 and Figure 4 As shown, a first motor 2 is fixedly connected to the bottom of the filter tank 1. A rotating block 21 is fixedly connected to the output end of the first motor 2. A stirring plate 22 is fixedly connected to the upper surface of the rotating block 21. An installation groove 201 is opened inside the stirring plate 22, and an absorption block 23 is installed inside the installation groove 201. During operation, when the filtered wastewater reaches the bottom of the filter tank 1, the operator can start the first motor 2. The first motor 2 starts and drives the rotating block 21 to rotate. The rotation of the rotating block 21 drives the stirring plate 22 to rotate. The rotation of the stirring plate 22 drives the absorption block 23 to stir the water. At the same time, the absorption block 23 absorbs and neutralizes the components in the water, reducing the content of harmful substances in the water and improving the filtration efficiency. Through the above structure, the function of rotating the absorption block 23 is realized by the cooperation of the first motor 2 and the rotating block 21. The absorption block 23 rotates at a constant speed to accelerate the water flow rate while absorbing and neutralizing harmful components in the water, reducing the difficulty of water treatment and improving the practicality of the device.
[0023] like Figure 1 , Figure 2 and Figure 5 As shown, a limiting block 46 is fixedly connected to the outer wall of the lifting block 42, and a limiting shaft 47 is fixedly connected to the top of the filter tank 1. The outer wall of the limiting shaft 47 is slidably connected to the inside of the limiting block 46. During operation, when the lifting block 42 moves, it will drive the limiting block 46 to slide on the outer wall of the limiting shaft 47, so that the lifting block 42 remains stable when moving. The filter tank 1 plays the role of overall support and fixation. Through the above structure, the cooperation of the limiting block 46 and the limiting shaft 47 realizes the function of limiting the movement of the lifting block 42, so that the lifting block 42 remains stable during the movement, and improves the stability of the device when sucking up impurities.
[0024] like Figure 1 and Figure 5 As shown, a drain port 3 is fixedly connected inside the filter tank 1. A water pump 31 is fixedly connected to the end of the drain port 3 away from the filter tank 1. A quartz sand filter element 32 is fixedly connected to the outer wall of the water pump 31. During operation, after the wastewater at the bottom of the filter tank 1 has been treated, the operator can start the water pump 31. The water pump 31 pumps the wastewater inside the filter tank 1 out through the drain port 3 and flows through the quartz sand filter element 32. After being filtered again by the quartz sand filter element 32, it reaches the next stage. Through the above structure, the function of quickly pumping out the wastewater inside the filter tank 1 is realized by the cooperation of the drain port 3 and the water pump 31. This allows the wastewater to be transported in a closed manner after treatment, improving the safety of the transportation process. At the same time, the quartz sand filter element 32 realizes secondary filtration of the wastewater, reducing the residual impurities in the wastewater and improving the filtration efficiency of the device.
[0025] like Figure 5 As shown, a sealing ring is provided on the inner wall of the limiting groove 401. During operation, the sealing ring on the inner wall of the limiting groove 401 improves the airtightness of the device when suctioning impurities and prevents wastewater leakage. Through the above structure, the sealing ring on the inner wall of the limiting groove 401 ensures that the lifting block 42 and the drain pipe 43 do not cause wastewater leakage when they move up and down, thus ensuring the stability of the internal air pressure of the filter tank 1 and improving the safety of the device during filtration.
[0026] like Figures 1 to 4 As shown, the filter disc 12, stirring plate 22, and drain pipe 43 are all made of stainless steel. During operation, using stainless steel for these components improves corrosion resistance, reduces liquid damage to the structure, and lowers maintenance costs. This structure, by using stainless steel for the filter disc 12, stirring plate 22, and drain pipe 43, enhances their corrosion resistance, enabling the device to operate for extended periods in liquid environments, improving its adaptability to different liquids, and extending its service life.
[0027] During operation, wastewater is added into the filter tank 1 through the inlet 11. The wastewater flows and collects on the surface of the filter disc 12, and then, under the action of gravity, passes through the collection cylinder 14 and the filter cylinder 15 and is discharged outwards. The filtered residue and particles will collect inside the collection cylinder 14 for subsequent absorption and transfer. When the filter cylinder 15 is saturated, the operator can disassemble and replace it. The filter cylinder 15 is quickly fixed by the cooperation of the fixing hole 101 and the fixing shaft 102. The fixing seat 13 and the fixing block 16 support and fix the filter cylinder 15. During operation, the inside of the filter tank 1 needs to be cleaned. When transferring accumulated impurities, the operator can start the second motor 4. The second motor 4 drives the lead screw 41 to rotate, which in turn moves the lifting block 42, which is threaded onto its outer wall, up and down. As the lifting block 42 moves, it moves the drain pipe 43. After the drain pipe 43 moves downwards a certain distance, it comes into contact with the impurities. At this point, the drain pump 44 is started, drawing out the impurities and creating an environment for subsequent filtration operations. The fixed cylinder 45 supports and fixes the drain pipe 43, and the limiting groove 401 limits the movement of the lifting block 42. During operation, after filtration... After the wastewater reaches the bottom of the filter tank 1, the operator can start the first motor 2. The first motor 2 drives the rotating block 21 to rotate, which in turn drives the stirring plate 22 to rotate. The stirring plate 22 then drives the absorption block 23 to agitate the water. Simultaneously, the absorption block 23 absorbs and neutralizes the components in the water, reducing the content of harmful substances and improving filtration efficiency. During operation, when the lifting block 42 moves, it causes the limiting block 46 to slide against the outer wall of the limiting shaft 47, ensuring the stability of the lifting block 42 during movement. The filter tank 1 provides overall support and fixation. When the wastewater at the bottom of the filter tank 1 is treated, the operator can start the water pump 31. The water pump 31 pumps the wastewater inside the filter tank 1 out through the drain port 3 and flows through the quartz sand filter element 32. After being filtered again by the quartz sand filter element 32, it reaches the next stage. During operation, a sealing ring is installed on the inner wall of the limiting groove 401 to improve the airtightness of the device when sucking up impurities and prevent wastewater leakage. During operation, the filter plate 12, the stirring plate 22 and the drain pipe 43 are all made of stainless steel, which improves corrosion resistance, reduces liquid damage to the structure and lowers maintenance costs.
