Description

Technical Field

[0001] This utility model belongs to the field of reaction tank stirring technology, and is particularly related to a reaction tank stirring device. Background Technology

[0002] Electroplating wastewater contains toxic heavy metal ions such as chromium, copper, and nickel. During treatment, chemical reagents such as ferrous sulfate and lime are continuously consumed in the reaction tank to separate and remove these heavy metal ions. After adding the chemicals to the reaction tank, a stirring device is needed to mix the wastewater and chemicals evenly and increase the reaction rate. Existing stirring equipment often uses a single motor to drive a single stirring rod. Because the reaction tank is large, multiple motors are needed to drive multiple stirring rods. This method consumes a lot of electricity, and multiple power sources are prone to damage, increasing production costs. Therefore, improvement is necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides a stirring device for an electroplating wastewater reaction tank, which can simultaneously drive multiple stirring rods to rotate via a single power source.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A stirring device for an electroplating wastewater reaction tank, comprising:

[0006] A linear mechanism is laterally positioned between a pair of strip support plates, with the moving end of the linear mechanism moving perpendicular to the strip support plates.

[0007] Multiple stirring rods are vertically arranged and rotatably connected to the movable end of a linear mechanism. Gears are coaxially connected to the top of each stirring rod, and multiple gears mesh with multiple racks. The racks are fixed between a pair of strip support plates.

[0008] Furthermore, the number of stirring rods is even, and they are arranged in multiple pairs along the length of the push plate. The racks are also arranged in multiple pairs along the length of the push plate, and the multiple pairs of racks are respectively located between the multiple pairs of stirring rods. Each pair of racks is provided with multiple fixing plates.

[0009] Furthermore, the linear mechanism includes a lead screw, a drive motor, and a strip-shaped movable plate. The lead screw is rotatably connected between a pair of strip-shaped support plates. The drive motor is connected to the output shaft of the lead screw. The strip-shaped movable plate is threadedly connected to the lead screw. A pair of guide rods are passed through the strip-shaped movable plate and fixed between the pair of strip-shaped support plates. Multiple stirring rods are rotatably connected to the strip-shaped support plates.

[0010] Furthermore, one side of the strip support plate is connected to multiple connecting seats by a first screw, and multiple stirring rods are rotatably connected to the multiple connecting seats respectively.

[0011] Furthermore, each of the strip support plates is equipped with a pair of U-shaped fixing seats at the bottom. The horizontal sections of the U-shaped fixing seats are connected to the bottom of the strip support plate, and the distance between the vertical sections of the U-shaped fixing seats matches the thickness of the walls at both ends of the reaction tank.

[0012] Furthermore, the distance between the outer sides of each pair of U-shaped fixing seats matches the distance between the two sides inside the reaction tank.

[0013] Furthermore, the transverse sections of the U-shaped fixing base are all threaded to the bottom of the strip support plate by the second screw, and the inner side of the transverse section is provided with a stepped groove to accommodate the screw head of the second screw.

[0014] The beneficial effects of this utility model are as follows:

[0015] This device uses a linear mechanism to drive multiple stirring rods to move back and forth along the length of the reaction tank simultaneously through a single power source. The multiple stirring rods rotate synchronously through a rack and pinion mechanism. Using a single power source to drive the rotation and movement of multiple stirring rods simplifies the equipment structure and reduces equipment costs and failure rates. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of the embodiments of this utility model clearer, the implementation methods of this utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this utility model are only some embodiments of this utility model, and not all embodiments.

[0024] This application provides a stirring device for an electroplating wastewater reaction tank, such as... Figures 1-6 As shown, it includes a linear mechanism 1, a stirring rod 3, etc.

[0025] Specifically, the linear mechanism 1 is horizontally positioned between a pair of strip support plates 2, and the moving direction of the movable end of the linear mechanism 1 is perpendicular to the strip support plate 2; there are multiple stirring rods 3, all of which are vertically positioned, and all of the stirring rods 3 are rotatably connected to the movable end of the linear mechanism 1. The top of each stirring rod 3 is coaxially connected to a gear 4, and the multiple gears 4 are respectively meshed with multiple racks 5, and the racks 5 are all fixed between a pair of strip support plates 2.

[0026] In actual use, a pair of strip support plates 2 are mounted on the top of both ends of the reaction tank. The linear mechanism 1 is started, and its movable end is controlled to move back and forth between the pair of strip support plates 2. During the movement of the movable end of the linear mechanism 1, multiple stirring rods 3 will follow. Because the gear 4 on the stirring rod 3 is meshed with the rack 5, the gear 4 will rotate during the movement of the stirring rod 3, thereby driving the stirring rod 3 to rotate, so as to realize the synchronous rotation of multiple stirring rods 3.

[0027] For details, please refer to Figure 1 , Figure 2 The linear mechanism 1 includes a lead screw 101, a drive motor 102, and a strip-shaped movable plate 103. The lead screw 101 is rotatably connected between a pair of strip-shaped support plates 2. The drive motor 102 is connected to the output shaft of the lead screw 101. The strip-shaped movable plate 103 is threadedly connected to the lead screw 101. A pair of guide rods 104 are threaded through the strip-shaped movable plate 103 and fixed between the pair of strip-shaped support plates 2. Multiple stirring rods 3 are rotatably connected to the strip-shaped support plates 2. By controlling the drive motor 102 to drive the lead screw 101 to rotate forward / reverse, the strip-shaped movable plate 103 can be moved back and forth between the pair of strip-shaped support plates 2.

[0028] Preferred options, please refer to Figure 1 , Figure 2 The number of stirring rods 3 is even, and they are arranged in multiple pairs along the length of the push plate. The racks 5 are also arranged in multiple pairs along the length of the push plate, and the multiple pairs of racks 5 are respectively arranged between the multiple pairs of stirring rods 3. Multiple fixing plates 501 are provided between each pair of racks 5. The stability of the racks 5 can be improved by connecting the multiple pairs of racks 5 through the fixing plates 501, and the racks 5 can be prevented from deforming due to the thrust of the gear 4.

[0029] For details, please refer to Figure 3 Figure 4 One side of the strip support plate 2 is connected to multiple connecting seats 6 by the first screw 601. Multiple stirring rods 3 are rotatably connected to multiple connecting seats 6 respectively. When installing the stirring device, the strip support plate 2 and the linear mechanism 1 can be installed on the reaction tank first, and then the connecting seats 6 and stirring rods 3 can be fixedly installed by the first screw 601.

[0030] For details, please refer to Figure 5 , Figure 6 Each strip support plate 2 has a pair of U-shaped fixing seats 7 at its bottom. The horizontal sections 701 of the U-shaped fixing seats 7 are connected to the bottom of the strip support plate 2, and the distance between the vertical sections 702 of the U-shaped fixing seats 7 matches the thickness of the walls at both ends of the reaction tank. When installing the strip support plate 2, the U-shaped fixing seats 7 can be quickly fixed by snapping them onto the tops of both ends of the reaction tank. More specifically, the distance between the outer sides of each pair of U-shaped fixing seats 7 matches the distance between the two sides inside the reaction tank. After the U-shaped fixing seats 7 are fixed to the top of the reaction tank, the outer sides of the U-shaped fixing seats 7 will abut against the inner side of the reaction tank, preventing the U-shaped fixing from moving along the length of the strip support plate 2. Preferably, the horizontal sections 701 of the U-shaped fixing seats 7 are threaded to the bottom of the strip support plate 2 by second screws 8, and the inner side of the horizontal sections 701 is provided with stepped grooves 7011 to accommodate the screw heads of the second screws 8, preventing the screw heads of the second screws 8 from abutting against the top of the reaction tank.

[0031] The above are only some of the embodiments listed in this application and are not intended to limit this application.
