Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a dosing device for industrial wastewater treatment. Background Technology

[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to wastewater and waste liquid generated during industrial production processes, containing industrial raw materials, intermediate products, by-products, and pollutants lost with the wastewater. Because industrial wastewater often contains various toxic substances, it pollutes the environment and poses a significant threat to human health. Therefore, it is essential to develop comprehensive utilization methods to turn harm into benefit. Appropriate purification measures must be implemented based on the composition and concentration of pollutants in the wastewater before it can be discharged.

[0003] The present announcement number is CN222181846U. A dosing device for industrial wastewater treatment includes a base plate. Support columns are symmetrically welded to one side of the top of the base plate. A dosing chamber is welded to the top of the symmetrically welded support columns. A feed hopper is welded to one side of the top of the dosing chamber. A discharge pipe is welded to one side of the bottom of the dosing chamber. A solenoid valve is installed on one side of the outer wall of the discharge pipe. A transmission rotating rod is movably installed at the bottom of the dosing chamber.

[0004] In the above scheme, when the spiral blades need to be replaced, even if the sealing baffle is disassembled and the maintenance opening is opened, it is not easy to take the spiral blades out of the dosing chamber, which increases the difficulty of personnel replacing the spiral blades. In addition, the device is equipped with two geared motors to realize the rotation of the spiral blades and the stirring blades respectively. This structural design will increase the production cost and maintenance cost of the device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a dosing device for industrial wastewater treatment, including a base plate 1, a dosing chamber 2 at the top of the base plate 1, a feed hopper 222 installed on the front side of the dosing chamber 2, and multiple support columns with convex rods 100 fixedly connected to the outside of the dosing chamber 2. All the support columns with convex rods 100 are fixedly connected to the base plate 1. A discharge pipe 200 is fixedly connected to one side of the bottom of the dosing chamber 2. A rectangular groove is opened at the top of the base plate 1, through which the discharge pipe 200 passes. A solenoid valve is installed on the outside of the discharge pipe 200. Rotating blocks 4 are provided on both sides of the dosing chamber 2, and a spiral blade rod 3 is provided between the two rotating blocks 4. The two rotating blocks 4 pass through both sides of the dosing chamber 2 and extend into the interior of the dosing chamber 2. Both rotating blocks 4 are rotatably connected to the dosing chamber 2. The two ends of the spiral blade rod 3 are fixed to the two rotating blocks 4 by bolts. One side of one rotating block 4... The device includes a drive unit, a stirring structure on one side of another rotating block 4, a cover plate 10 on the top of the dosing chamber 2, two support column convex rods 100 fixedly connected to the bottom of the cover plate 10, two protrusions 111 on the top of the dosing chamber 2, the support column convex rods 100 being disposed inside the protrusions 111 and slidably connected to the dosing chamber 2, a connecting plate 201 fixedly connected to one side of the dosing chamber 2, two protrusions 202 on the top of the connecting plate 201 corresponding to the protrusions 111, two positioning grooves 112 on the top of the dosing chamber 2, a U-shaped plate 14 on the top of the cover plate 10, both ends of the U-shaped plate 14 passing through the top of the cover plate 10 and extending into the two positioning grooves 112, the U-shaped plate 14 being slidably connected to the cover plate 10, a piston plate 11 inside the dosing chamber 2, and an adjustment structure between the piston plate 11 and the U-shaped plate 14.

[0024] The adjustment structure includes an internally threaded cylinder 12, which is located on the top of the cover plate 10. The bottom end of the internally threaded cylinder 12 passes through the top of the cover plate 10 and extends into the interior of the cover plate 10. The internally threaded cylinder 12 is rotatably connected to the cover plate 10. A worm gear 15 is fixedly connected to the outside of the internally threaded cylinder 12. A worm 16 is meshed with the outside of the worm gear 15. Two support blocks are rotatably connected to the outside of the worm 16. Both support blocks are fixedly connected to the cover plate 10. A throttle is installed at one end of the worm 16. A threaded rod 13 is threadedly connected inside the internally threaded cylinder 12. The two ends of the threaded rod 13 are fixedly connected to the piston plate 11 and the U-shaped plate 14, respectively.

[0025] Specifically, when the throttle is turned, the worm gear 16 meshes with the worm wheel 15, and the worm wheel 15 drives the internal threaded cylinder 12 to rotate on the cover plate 10. The internal threaded cylinder 12 is threadedly connected to the threaded rod 13, and the threaded rod 13 drives the U-shaped plate 14 and the piston plate 11 to move upward. The piston plate 11 moves into the cover plate 10, while the two ends of the U-shaped plate 14 move out from the two positioning grooves 112, thereby releasing the limit on the cover plate 10 and pushing the cover plate 10. The two support column convex rods 100 slide from the two convex grooves 111 to the two convex grooves 202, and the bolts on the two rotating blocks 4 are removed, so that personnel can easily remove the spiral blade rod 3 from the inside of the dosing chamber 2.

A stirring rod 9 is fixedly connected to the bottom of the bevel gear 8. The stirring rod 9 passes through the bottom plate 1 and is rotatably connected to the bottom plate 1.

[0028] Specifically, starting the geared motor 300 (the specific model of the geared motor 300 is not limited, but depends on the compatible equipment) drives one of the rotating blocks 4 to rotate. One of the rotating blocks 4 drives the other rotating block 4 to rotate via the helical blade rod 3. The two rotating blocks 4 rotate on the dosing chamber 2. The other rotating block 4 drives the first bevel gear 7 to rotate via the rotating shaft rod 5. The first bevel gear 7 meshes with the second bevel gear 8, thereby realizing the rotation of the stirring rod 9. Therefore, this device only needs one geared motor 300 to realize the rotation of the helical blade rod 3 and the stirring rod 9, eliminating the need for two geared motors 300, thus reducing the production and maintenance costs of the device.
