Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical wastewater treatment technology, specifically to an industrial wastewater flocculation and sedimentation device. Background Technology

[0002] Pharmaceutical manufacturing processes generate large amounts of wastewater containing suspended particulate matter, colloidal pollutants, and soluble impurities. Direct discharge of this wastewater would severely damage aquatic ecosystems, pollute soil and groundwater resources, and threaten human health and ecological balance. Therefore, it must undergo strict treatment to meet standards before discharge. Flocculation sedimentation, as a core solid-liquid separation process in industrial wastewater treatment, is widely used in the pretreatment or advanced treatment of wastewater in various industries such as chemical, printing and dyeing, metallurgy, and food processing due to its advantages of low treatment cost, simple operation, and wide applicability. Its core principle is to add flocculants (such as polyaluminum chloride and polyacrylamide) to the wastewater, causing fine suspended particles and colloids to aggregate through adsorption and bridging to form loosely structured, large-volume flocs (flocs), which are then separated from the water by gravity settling.

[0003] However, existing industrial wastewater flocculation and sedimentation devices still have technical defects in practical applications, such as imperfect filtration. Most existing devices adopt a single sedimentation or simple filtration structure, and the fine flocs and trace pollutants remaining in the wastewater after sedimentation are difficult to completely intercept, making it difficult for the effluent quality to meet increasingly stringent environmental emission standards. Additional downstream treatment equipment is required, which increases treatment costs and floor space. Utility Model Content

The inner side of the horizontal plate 57 contacts the fixed shell 51. The end of the locking rod 56 away from the drive frame 55 passes through the fixed shell 51 and extends into the interior of the horizontal plate 57.

[0019] As a technical optimization of this utility model, by setting the connecting mechanism 5, it is convenient for users to disassemble the filter tank 35. The user can rotate the transmission shaft 52 to drive the rotating disk 53 inside the fixed shell 51 to rotate, so that the rotating shaft 54 ​​drives the transmission frame 55 to move longitudinally, thereby driving the locking rod 56 to engage or disengage from the interior of the horizontal plate 57 on the surface of the filter tank 35, realizing the quick assembly and disassembly of the filter tank 35 and the sedimentation box 103. Compared with the traditional fixed connection method, it is easier to periodically disassemble the filter tank 35 to replace or clean the internal filter elements, reduce the maintenance difficulty, and extend the overall service life of the device.

[0020] refer to Figure 2The stirring mechanism 2 includes a motor 21, which is fixedly connected to the left side of the sedimentation box 103. The output end of the motor 21 passes through the sedimentation box 103 and extends into the interior of the sedimentation box 103, where a connecting shaft 22 is fixedly connected. A stirring blade 23 is fixedly connected to the surface of the connecting shaft 22.

[0021] As a technical optimization of this utility model, by setting up a stirring mechanism 2, the industrial wastewater after the flocculant is added can be fully stirred, which breaks the defect of insufficient mixing in traditional devices, promotes fine suspended particles and colloids to contact the flocculant more evenly, forms flocs with larger volume and stronger stability, accelerates the floc settling speed, improves the pollutant removal rate, and reduces the risk of clogging of subsequent filter components.

[0022] refer to Figure 4 The bottom of the filter box 4 is fixedly connected to the top of the base 101. The filter box 4 includes a storage shell 41.

[0026] refer to Figure 3 A stabilizing bearing 8 is fixedly connected to the surface of the drive shaft 52, and the front of the outer ring of the stabilizing bearing 8 is fixedly connected to the front of the inner wall of the fixed housing 51.

[0027] As a technical optimization of this utility model, by setting a stable bearing 8, the rotation trajectory of the transmission shaft 52 can be limited, reducing the radial sway when the transmission shaft 52 rotates, avoiding wear of components such as the rotating disk 53 and rotating shaft 54 ​​due to the offset of the transmission shaft 52, improving the operational stability of the transmission mechanism, reducing the probability of component failure, and extending the service life of the connecting mechanism 5.

[0028] The working principle and usage process of this utility model are as follows: In use, industrial wastewater to be treated is first transported into the sedimentation box 103 through water pipes 106 on both sides of the top front end of the cover plate 104 in the sedimentation device 1. Simultaneously, flocculant is added into the sedimentation box 103 through flocculant transfer pipes 105 on both sides of the top rear end of the cover plate 104. Then, the stirring mechanism 2 is activated, and the motor 21 fixed on the left side of the sedimentation box 103 outputs power, driving the connecting shaft 22, whose output end extends into the sedimentation box 103, to rotate. The stirring blades 23 on the surface of the connecting shaft 22 rotate accordingly within the sedimentation box 103, thoroughly mixing the industrial wastewater and flocculant. This causes the fine suspended particles and colloidal pollutants in the wastewater to aggregate through adsorption and bridging, forming flocs with a larger volume and density greater than water. Then, stirring is stopped, and the flocs in the sedimentation box 103 undergo gravity-induced self-discharge. After settling, a clear liquid is formed on the upper layer and flocculent sediment is formed on the lower layer, completing the initial solid-liquid separation. Then, the filtration mechanism 3 is started, and the water pump 31 draws the clear liquid in the middle layer of the sedimentation box 103 through the water inlet pipe 32 connected to the water inlet. The clear liquid is transported to the pipe 34 on the front of the sedimentation box 103 through the water outlet pipe 33 connected to the water outlet pipe 31, and then enters the filter tank 35 connected to the bottom of the water outlet pipe 33 through the pipe 34 for preliminary filtration. Then, the filter tank 35 transmits the filtered water to the interior of the filter box 4 through the connecting pipe 36. The filter screen 43, which is fixed horizontally inside the storage shell 41 of the filter box 4, first intercepts the larger flocculent impurities remaining in the wastewater, and then the wastewater is filtered a second time through the filter screen 42 to intercept the fine flocculents and trace pollutants. Finally, the flocculation sedimentation and multi-stage filtration treatment of industrial wastewater are completed to obtain clean water that meets the discharge standards.

[0029] In summary, this industrial wastewater flocculation and sedimentation device solves the problem of inconvenient maintenance of traditional integrated structures by setting up a sedimentation device 1; it also improves the flocculation and mixing effect by setting up a stirring mechanism 2; then it filters the settled wastewater through a filtration mechanism 3, and finally filters the wastewater a second time through a filter box 4, thereby reducing wastewater transfer links, avoiding floc breakage, and improving treatment efficiency.
