Description

Technical Field

[0001] This utility model relates to the field of electroplating wastewater treatment technology, and in particular to a device for treating electroplating wastewater from door control hardware parts. Background Technology

[0002] The electroplating process for door hardware generates a large amount of electroplating wastewater. The composition of electroplating wastewater is very complex. In addition to cyanide and acids and alkalis, heavy metals are a category of wastewater with extremely high potential hazards in the electroplating industry. These substances seriously endanger the environment and human health. Therefore, treatment equipment is needed to treat the wastewater discharged from electroplating production.

[0003] A search revealed that Chinese Patent Publication No. CN216038790U discloses a flocculation device for purifying electroplating wastewater. The device features an open, hollowed-out feeding box. After the flocculant is placed into the open feeding box, it drains directly through the holes. A rodless cylinder drives the open feeding box to reciprocate left and right. The rotation of a first motor drives the open feeding box to rotate, thereby ensuring that the flocculant is evenly added and improving the flocculation efficiency. In conjunction with a second motor driving the stirring shaft to rotate, the flocculation efficiency is further improved.

[0004] However, the above technical solution has the following disadvantages when used:

[0005] Firstly, the flocculant in this electroplating wastewater purification flocculation device is allowed to leak directly through the perforation, which can easily affect the thorough mixing between the electroplating wastewater and the flocculant. Secondly, the stirring structure in this flocculation device is in a fixed position, which cannot fully mix the wastewater and flocculant from all directions. It requires a long stirring time to achieve the required mixing state. Therefore, its practicality needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the background art by proposing a device for treating electroplating wastewater of door-controlled hardware parts.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A device for treating electroplating wastewater from door-controlled hardware components includes:

[0009] The treatment tank has a storage tank fixedly connected to its top, and a wastewater pipe fixedly connected to the outer wall of the treatment tank and a sludge pump fixedly installed thereon, with the sludge pump inlet connected to the treatment tank.

[0010] The agitation assembly includes a lead screw fixedly installed inside the processing tank and arranged vertically. An I-shaped nut is threaded onto the outer wall of the lead screw. A fixing tube is fixedly installed at the bottom of the I-shaped nut. Multiple agitating rods are fixedly installed on the outer wall of the fixing tube. A lifting plate is movably engaged with the recess of the lead screw. A fixing rod is fixedly installed on the top of the lifting plate, and the end of the fixing rod away from the lifting plate movably passes through the top of the processing tank. A rectangular frame is fixedly installed at the upper end of the fixing rod, and a crankshaft is slidably arranged inside the rectangular frame. A motor for driving the crankshaft is fixedly installed on the outer wall of the storage tank.

[0011] Preferably, the bottom of the storage tank is fixedly connected to an outlet pipe that extends through the top of the processing tank, and a piston is airtightly fitted inside the outlet pipe. A connecting rod is fixedly installed at the bottom of the piston, and the bottom of the connecting rod is fixedly installed with the lifting plate.

[0012] Preferably, the fixing tube is movably sleeved on the lead screw, and the inner diameter of the fixing tube is larger than the outer diameter of the lead screw.

[0013] Preferably, the diameter of the crankshaft is equal to the inner width of the rectangular frame.

[0014] Preferably, both ends of the lifting plate are movably attached to the inner surface of the processing tank.

[0015] Compared with existing technologies, the advantages of the door-controlled hardware electroplating wastewater treatment device provided by this utility model are as follows:

[0016] 1. The crankshaft is driven by a motor to rotate, which can move the rectangular frame to move the fixed rod and the lifting plate up and down synchronously. This allows the I-shaped nut to move up or down along the screw along with the lifting plate, so that the fixed tube can rotate while moving up and down. This increases the contact range of the stirring rod with the electroplating wastewater and flocculant in the treatment tank, so that the flocculant and electroplating wastewater can be fully mixed in a short time, thereby improving the mixing efficiency of electroplating wastewater and flocculant.

[0017] 2. When the lifting plate moves up and down, it can also drive the piston to move back and forth synchronously through the connecting rod, so that the flocculant can be fed intermittently, thereby avoiding the microbial flocculant in the storage tank from sliding into the treatment tank and causing insufficient mixing with the electroplating wastewater.

[0018] In summary, this utility model increases the contact range of the stirring rod with the electroplating wastewater and flocculant in the treatment tank by using a fixed tube that can move up and down and rotate on its own, so that the flocculant and electroplating wastewater can be fully mixed in a short time. At the same time, the flocculant can be fed intermittently, thereby improving the mixing efficiency of electroplating wastewater and flocculant. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 3 A device for treating electroplating wastewater from door-controlled hardware components, comprising:

[0025] The treatment tank 1 has a storage tank 2 fixedly connected to its top, and a wastewater pipe 3 fixedly connected to the outer wall of the treatment tank 1, with a sludge pump 4 fixedly installed thereon. The inlet of the sludge pump 4 is connected to the treatment tank 1. During use, the electroplating wastewater from the door control hardware can be introduced into the treatment tank 1 through the wastewater pipe 3. After treatment, when it is necessary to discharge the electroplating wastewater in the treatment tank 1, the sludge pump 4 can be started to transport the flocculated electroplating wastewater in the treatment tank 1 to an external wastewater sedimentation tank for sedimentation treatment.

[0026] The agitation assembly includes a lead screw 5 fixedly installed inside the processing tank 1 and arranged vertically. An I-shaped nut 6 is threaded onto the outer wall of the lead screw 5. A fixing tube 7 is fixedly installed at the bottom of the I-shaped nut 6. The fixing tube 7 is movably sleeved on the lead screw 5, and the inner diameter of the fixing tube 7 is larger than the outer diameter of the lead screw 5 to avoid the fixing tube 7 from contacting the lead screw 5 and to ensure the normal rotation of the fixing tube 7.

[0027] Multiple stirring rods 8 are fixedly installed on the outer wall of the fixed tube 7. A lifting plate 9 is movably engaged in the recess of the screw 5. Both ends of the lifting plate 9 are movably attached to the inner surface of the treatment tank 1, which makes the lifting plate 9 more stable during the lifting process.

[0028] A fixing rod 10 is fixedly installed on the top of the lifting plate 9, and the end of the fixing rod 10 away from the lifting plate 9 extends through the top of the treatment tank 1. A rectangular frame 11 is fixedly installed on the upper end of the fixing rod 10, and a crankshaft 12 is slidably arranged inside the rectangular frame 11. The diameter of the crankshaft 12 is equal to the inner width of the rectangular frame 11. A motor 13 for driving the crankshaft 12 is fixedly installed on the outer wall of the storage tank 2. In use, flocculant is first poured into the storage tank 2, and then the motor 13 is started to drive the crankshaft 12 to rotate, so that the end of the crankshaft 12 away from the motor 13 moves in a circular motion. By sliding within the rectangular frame 11, the crankshaft 12 is moved, causing the rectangular frame 11 to move. Rod 10 and lifting plate 9 move up and down synchronously. Then, lifting plate 9 pulls and pushes I-shaped nut 6 to move up and down on the surface of screw 5. At the same time, under the thread engagement of I-shaped nut 6 and screw 5, I-shaped nut 6 can move up or down along screw 5 as lifting plate 9 moves up and down. This allows fixed pipe 7 to rotate while moving up and down, increasing the contact range of stirring rod 8 with electroplating wastewater and flocculant in treatment tank 1, so that flocculant and electroplating wastewater can be fully mixed in a short time, thereby improving the mixing efficiency of electroplating wastewater and flocculant.

[0029] Furthermore, the bottom of the storage tank 2 is fixedly connected to an outlet pipe 14 that runs through the top of the treatment tank 1, and a piston 15 is airtightly fitted inside the outlet pipe 14. A connecting rod 16 is fixedly installed at the bottom of the piston 15, and the bottom of the connecting rod 16 is fixedly installed with the lifting plate 9. When the lifting plate 9 moves up and down, the piston 15 can also be driven to move back and forth synchronously through the connecting rod 16. When the piston 15 is placed in the outlet pipe 14, the flocculant will not fall; otherwise, the flocculant will fall into the treatment tank 1. By repeating this process, the microbial flocculant can be intermittently fed, thereby preventing all the microbial flocculant in the storage tank 2 from sliding into the treatment tank 1 and causing insufficient mixing with the electroplating wastewater.

[0030] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
