Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a metal recovery device for wastewater treatment in municipal engineering. Background Technology

[0002] Wastewater treatment refers to the purification process of treating wastewater through multiple stages to meet water quality discharge standards. In municipal engineering, wastewater needs to undergo purification treatment at multiple stages.

[0003] Among them, a search revealed an application with application number CN202122866928.6, entitled "A Wastewater Treatment Device for Chemical Production." This wastewater treatment device features a stirring device to agitate the chemical wastewater, and a sedimentation tank to deposit rare metals in the wastewater to the bottom, thereby effectively recovering the rare metals and reducing unnecessary waste. However, its shortcomings are as follows:

[0004] When this type of wastewater treatment device for chemical production is used by workers to treat large amounts of chemical wastewater carrying metal scrap, the process is quite labor-intensive. It relies solely on stirring the wastewater to allow the large amounts of non-ferrous metals to settle naturally, followed by manual collection of the scrap. This results in low efficiency and a heavy workload for the workers. Furthermore, the large spacing between the three agitators prevents effective mixing of the wastewater, leading to poor mixing results. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the manual collection of large amounts of non-ferrous metal waste in the above-mentioned chemical production wastewater treatment device is labor-intensive and inefficient, and cannot effectively mix and treat the wastewater, so as to provide a metal recovery device for wastewater treatment in municipal engineering.

[0006] The technical solution adopted by this utility model is as follows: A metal recovery device for sewage treatment in municipal engineering includes a sewage treatment chamber, an inlet, a fixed frame, an outlet, a valve, a water guide frame A, a support frame, and a water storage tank. The inlet is embedded in the top of the outer wall of the sewage treatment chamber, and the outlet is embedded in the bottom of the outer wall of the sewage treatment chamber. A valve is nested in the top of the outer wall of the outlet. A water storage tank is located at the bottom of the outer side of the sewage treatment chamber near the outer side of the outlet. The water guide frame A is fixedly installed on the top of the inner wall of the sewage treatment chamber. A support frame is slidably installed at one end of the top of the inner side of the sewage treatment chamber, and the support frame and the sewage treatment chamber are connected by bolts. A fixed frame is fixedly installed at one end of the bottom of the outer wall of the sewage treatment chamber. A rotating filter mechanism is provided on the outside of the support frame to filter and recover metal waste impurities carried in the sewage. A stirring disinfection mechanism is provided at the bottom of the inner side of the sewage treatment chamber to uniformly contact and mix large amounts of sewage with chlorine dioxide disinfectant for disinfection.

[0007] The rotating filter mechanism consists of a servo motor A, a rotating frame, a limiting groove, a filter frame, a limiting block, a filter screen, a water guide frame B, and an electromagnet.

[0008] A rotating frame is rotatably mounted on one top outer side of the support frame via a bearing. A servo motor A is fixedly mounted on the other top inner wall of the support frame, and the servo motor A is connected to the rotating frame via a chain drive through an output shaft. A limit groove is embedded in the bottom outer wall of the rotating frame, and the limit groove is arranged in a ring shape. A filter frame is set on the bottom outer side of the rotating frame. A limit block is fixedly mounted on the top outer wall of the filter frame, and the limit block is slidably positioned inside the limit groove. The limit groove and the limit block are connected by bolts. Filter screens are bolted to both the top and bottom ends of the outer wall of the filter frame, and the mesh size of the filter screens is arranged from largest to smallest from top to bottom. A water guide frame B is bolted to the middle of the inner wall of the filter frame. Electromagnets are fixedly mounted on both the left and right sides of one bottom outer wall of the water guide frame B. There are several electromagnets, which are arranged in a equidistant ring.

[0009] The stirring disinfection mechanism consists of a servo motor B, a rotating rod, blades, a stirring block, a water guide channel, a water spray head, a chlorine dioxide disinfectant tank, and a water pump.

[0010] Servo motors B are fixedly installed at both ends of the bottom of the inner wall of the wastewater treatment room. Rotating rods are connected to the top of the outer sides of each servo motor B via output shafts. Several blades are fixedly installed on the outer wall of each rotating rod, arranged symmetrically in a central arrangement, with the blades interlacing between each other. Stirring blocks are fixedly installed at the upper and lower ends of the outer walls of each blade, arranged equidistantly in a central arrangement. A water guide groove is embedded in the top of the inner wall of the rotating rod. Spray heads are nested near the blades at both ends of the outer wall of the water guide groove, arranged symmetrically in a central arrangement. A chlorine dioxide disinfectant tank is fixedly installed on the top of the outer wall of the fixed frame. A water pump is embedded in the front end of the outer wall of the chlorine dioxide disinfectant tank, and the chlorine dioxide disinfectant tank and the water pump are connected by a water guide hose.

[0014] 1. This type of municipal engineering sewage treatment metal recovery device is equipped with electromagnets. When the operator turns on the servo motor A, the rotating frame is driven by the chain. When a large amount of sewage falls on the surface of the two filter screens on the outside of the filter frame, the impurities in the sewage are blocked by the filter screens. When the sewage passes through the guide frame B, the operator turns on several electromagnets to generate magnetism, which adsorbs the smaller metal wastes carried in the sewage, thereby improving the filtration and classification of impurities and metal wastes in the sewage.

[0015] 2. This type of metal recovery device for sewage treatment in municipal engineering is equipped with blades and spray heads. Simultaneously, the operator activates two servo motors B to rotate the outer blades of the rotating rod in opposite directions. At the same time, the operator turns on the water pump to introduce chlorine dioxide disinfectant from the chlorine dioxide disinfectant tank into the inner side of two water guide channels through a water guide hose. This chlorine dioxide is then sprayed into the sewage over a wide area from several rotating spray heads, ensuring extensive and uniform contact between the sewage and the chlorine dioxide disinfectant. This agitates and disinfects the sewage, improving the effectiveness of the uniform contact disinfection process. Attached Figure Description

[0022] In this utility model:

[0023] Reference Figure 1-4 A metal recycling device for sewage treatment in municipal engineering includes a sewage treatment chamber 1, an inlet 101, a fixing frame 102, an outlet 103, a valve 1031, a water guide frame A104, a support frame 2, and a water storage tank 5. The inlet 101 is embedded in the top of the outer wall of the sewage treatment chamber 1, and the outlet 103 is embedded in the bottom of the outer wall of the sewage treatment chamber 1. The valve 1031 is nested in the top of the outer wall of the outlet 103. The water storage tank 5 is located at the bottom outer side of the sewage treatment chamber 1 near the bottom outer side of the outlet 103. A water guide frame A104 is fixedly installed on the top of the inner wall of the wastewater treatment chamber 1. A support frame 2 is slidably installed on one end of the top inner side of the wastewater treatment chamber 1, and the support frame 2 and the wastewater treatment chamber 1 are connected by bolts. A fixing frame 102 is fixedly installed on one end of the bottom outer wall of the wastewater treatment chamber 1. A rotating filter mechanism is provided on the outside of the support frame 2 to filter and recycle metal waste impurities carried in the wastewater. A stirring disinfection mechanism is provided on the bottom inner side of the wastewater treatment chamber 1 to uniformly contact and mix a large amount of wastewater with chlorine dioxide disinfectant for disinfection.

[0024] Reference Figure 1-3 Furthermore, the rotating filter mechanism consists of a servo motor A201, a rotating frame 202, a limiting groove 203, a filter frame 204, a limiting block 205, a filter screen 206, a water guide frame B207, and an electromagnet 208.

[0025] A rotating frame 202 is rotatably mounted on one top outer side of the support frame 2 via a bearing. A servo motor A201 is fixedly mounted on the other top inner wall of the support frame 2, and the servo motor A201 is connected to the rotating frame 202 via a chain drive through an output shaft. A limiting groove 203 is embedded in the bottom outer wall of the rotating frame 202, and the limiting groove 203 is arranged in a ring shape. A filter frame 204 is provided on the bottom outer side of the rotating frame 202, and a limiting block 205 is fixedly mounted on the top outer wall of the filter frame 204, and the limiting block 205 is slidably engaged with the limiting groove 202. 3. The inner side of the filter frame 204 is connected to the limiting groove 203 and the limiting block 205 by bolts. The upper and lower ends of the outer wall of the filter frame 204 are connected to the filter screen 206 by bolts, and the mesh size of the filter screen 206 is arranged from large to small from top to bottom. The middle of the inner wall of the filter frame 204 is connected to the water guide frame B207 by bolts. Electromagnets 208 are fixedly installed on both the left and right sides of one end of the bottom outer wall of the water guide frame B207. There are several electromagnets 208, which are arranged in a equidistant ring. When the staff needs to process the large amount of sewage generated after the construction of a large number of municipal engineering projects, During treatment, staff pour a large amount of wastewater into the wastewater treatment chamber 1 through inlet 101 and turn on the servo motor A201. The chain on the outer side of the output shaft drives the rotating frame 202 to rotate clockwise and counterclockwise continuously through the bearings. This causes the large amount of wastewater to fall onto the filter screen 206 at the top of the filter frame 204. Larger impurities in the wastewater are blocked by the filter screen 206, filtering out some of the impurities. The wastewater, carrying smaller impurities, passes through the filter screen 206 at the top of the filter frame 204 and then through the guide frame B207. Personnel activate several electromagnets 208 to generate magnetism, attracting smaller metal waste and other particles carried in the wastewater. The wastewater then passes through another filter screen 206 to filter out the smaller impurities before falling into the bottom of the wastewater treatment chamber 1. At this point, the workers unscrew the bolts on the outer wall of the support frame 2 and pull the support frame 2 out of the wastewater treatment chamber 1. After unscrewing the bolts on the surface of the filter screen 206 and the water guide frame B207, the filtered impurities are processed, and the filtered metal waste is collected and recycled to other processing areas.

[0026] Reference Figure 1 , 2 4. Furthermore, the stirring disinfection mechanism consists of a servo motor B3, a rotating rod 301, a blade 302, a stirring block 303, a water guide trough 304, a spray head 305, a chlorine dioxide disinfectant tank 4, and a water pump 401.

[0027] Servo motors B3 are fixedly installed at both ends of the bottom of the inner wall of the wastewater treatment chamber 1. Rotating rods 301 are connected to the top of the outer side of each servo motor B3 via output shafts. Several blades 302 are fixedly installed on the outer wall of each rotating rod 301, arranged symmetrically in a central arrangement. The blades 302 on the outer wall of two rotating rods 301 are interlaced. Stirring blocks 303 are fixedly installed at the upper and lower ends of the outer wall of each blade 302, arranged equidistantly in a parallel arrangement. The rotating rods... A water guide groove 304 is embedded in the top of the inner wall of the rod 301. Spray heads 305 are nested at both ends of the outer wall of the water guide groove 304 near the blades 302. Several spray heads 305 are arranged symmetrically and equidistantly in a central arrangement. A chlorine dioxide disinfectant tank 4 is fixedly installed on the top of the outer wall of the fixing frame 102. A water pump 401 is embedded in the front end of the outer wall of the chlorine dioxide disinfectant tank 4. The chlorine dioxide disinfectant tank 4 and the water pump 401 are connected by a water guide hose. The ends are rotated by bearings and sealing rings and nested on the top of the outer wall of the water guide trough 304. After a large amount of filtered sewage falls into the bottom of the inner side of the sewage treatment chamber 1, the staff turns on the two servo motors B3 to drive the outer blades 302 of the rotating rod 301 to rotate in opposite directions. At the same time, the staff turns on the water pump 401 to introduce the chlorine dioxide disinfectant in the chlorine dioxide disinfectant tank 4 into the inner side of the two water guide troughs 304 through the water guide hose. After being sprayed into the sewage from several rotating spray heads 305, the sewage and chlorine dioxide disinfectant will have a large-scale uniform contact. After the sewage is agitated and disinfected, the staff opens the outer valve 1031 of the outlet 103 to discharge a large amount of disinfected sewage into the storage tank 5. The staff then places the next storage tank 5 at the bottom of the outlet 103 and treats the sewage in the same way. After that, the staff transports several storage tanks 5 filled with disinfected sewage to the sewage treatment plant for purification.

[0028] Reference Figure 1-3 Furthermore, valve 1031, servo motor A201, electromagnet 208, servo motor B3 and water pump 401 are all electrically connected to an external power source via a control panel.

[0029] Reference Figure 2 , 3 Furthermore, the outer surface material of filter screen 206 is all modified PVC. Because modified PVC material has the characteristics of high and low temperature resistance and aging resistance, it can prevent the outer surface of filter screen 206 from aging faster and being easily damaged when it is in contact with sewage of different temperatures for a long time.

[0030] like Figure 2 , 3As shown, in addition to the embodiment where the outer surface material of the filter screen 206 is all modified PVC, there is another embodiment where the outer surface material of the filter screen 206 is all polytetrafluoroethylene (PTFE). Because PTFE has the characteristics of high and low temperature resistance, non-flammability, corrosion resistance, and aging resistance, the filter screen 206 will not age faster and be easily damaged when it is in contact with sewage of different temperatures for a long time. At the same time, the PTFE material of the filter screen 206 has high lubricity and non-adhesion properties, so that after a large amount of debris is filtered and remains on the surface of the filter screen 206, the debris will not adhere to the surface of the filter screen 206 and be difficult to clean.

[0031] Working Principle: First, when workers need to treat large amounts of wastewater generated after municipal engineering construction, they pour the wastewater into the wastewater treatment chamber 1 through inlet 101. Then, servo motor A201 is turned on, driving the rotating frame 202 to rotate clockwise and counterclockwise through the bearing via the chain on the output shaft. This causes the wastewater to fall onto the filter screen 206 at the top of the filter frame 204, where larger impurities are blocked by the filter screen 206. After filtering out some of the impurities, the wastewater carrying smaller impurities passes through the filter screen 206 at the top of the filter frame 204 and then through the guide frame B207. At this point, several electromagnets 208 are activated to generate magnetism, attracting smaller metal scraps from the wastewater. The wastewater then passes through another filter screen 206, where smaller impurities are filtered out, before falling into the bottom of the wastewater treatment chamber 1. After the large amount of filtered wastewater falls into the bottom of the wastewater treatment chamber 1, the workers turn on two servo motors B3, driving the outer blades 302 of the rotating rod 301 towards the opposite direction. As the blades 302 rotate in the direction of rotation, they continuously weave and rotate in the sewage. Simultaneously, the operator turns on the water pump 401 to introduce chlorine dioxide disinfectant from the chlorine dioxide disinfectant tank 4 through the water guide hose into the inner side of the two water guide channels 304. This chlorine dioxide is then sprayed extensively into the sewage from several rotating nozzles 305, ensuring widespread and uniform contact between the sewage and the chlorine dioxide disinfectant. After agitating and disinfecting the sewage, the operator opens the outer valve 1031 of the outlet 103, allowing a large amount of disinfected sewage to be discharged into the storage tank 5. Afterwards, the staff placed the next water storage tank 5 at the bottom of the outlet 103 and treated the sewage in the same way. Then, the staff transported several water storage tanks 5 filled with disinfected sewage to the sewage treatment plant for purification. Finally, the staff periodically unscrewed the bolts on the outer wall of the support frame 2 and pulled the support frame 2 out of the sewage treatment chamber 1. After unscrewing the bolts on the surface of the filter screen 206 and the water guide frame B207, the filtered impurities were treated, and the filtered metal waste was collected and recycled to other processing sites.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
