DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown, a flocculant delivery device for industrial wastewater purification includes a wastewater tank 1 for storing wastewater and a working tank 2 arranged on the wastewater tank 1. A partition 3 is arranged inside the working tank 2, and the partition 3 divides the inside of the working tank 2 into an upper working area and a lower raw material area 4. The inside of the lower raw material area 4 is used to temporarily store flocculants. A feed port 5 is provided between the lower raw material area 4 and the wastewater tank 1. A piston 6 located below the feed port 5 is movably arranged inside the wastewater tank 1. A driving member is arranged inside the upper working area, and the driving member is used to drive the piston 6 to open or block the feed port 5. At the same time, an inlet pipe 16 and an outlet pipe 17 can be respectively arranged on both sides of the wastewater tank 1, and wastewater can be transported to the inside of the wastewater tank 1 via the inlet pipe 16. When the piston 6 is driven by the driving member to open the feed port 5, the flocculant located in the lower raw material area 4 can be transported from the feed port 5 into the inside of the wastewater tank 1, and the flocculant can react with the wastewater. When the driving member drives the piston 6 to close the feed port 5, the flocculant located inside the lower raw material area 4 cannot be discharged. Then, by intermittently opening or blocking the feed port 5, the flocculant can be intermittently transported to the inside of the wastewater tank 1, achieving convenient transportation and easy use.

[0025] As an implementation method in this embodiment, the driving member includes a cam 7 rotatably installed inside the upper working area and a movable plate 8 vertically movably installed inside the upper working area, and the cam 7 is pressed and connected with the movable plate 8, a first motor 9 is fixedly provided at the bottom of the movable plate 8, and a rotating shaft 10 is fixedly provided on the output shaft of the first motor 9, the rotating shaft 10 movably passes through the lower raw material area 4 and extends into the interior of the wastewater tank 1, and the piston 6 is fixedly provided on the rotating shaft 10.

[0026] As an implementation method in this embodiment, Figure 1 As shown, at this time, the piston 6 blocks the feed port 5. If the feed port 5 needs to be opened, the cam 7 can be driven to rotate. The rotation of the cam 7 can press the movable plate 8, so that the movable plate 8 drives the rotating shaft 10 and the piston 6 to move downward. The downward movement of the piston 6 can open the feed port 5, so that the flocculant located in the lower raw material area 4 can be transported to the inside of the wastewater tank 1. This state can be controlled by Figure 3 After the flocculant is transported to the wastewater tank 1, the first motor 9 can be started, and the output shaft of the first motor 9 can drive the rotating shaft 10 to rotate. At the same time, a spiral stirring blade 14 is fixedly provided on the rotating shaft 10 outside the wastewater tank 1. When the rotating shaft 10 rotates, the spiral stirring blade 14 will rotate, thereby stirring the wastewater and flocculant in the wastewater tank 1, so that the flocculant and the wastewater react fully.

[0027] As an implementation method in this embodiment, in order to enable the rotation of the cam 7 to intermittently open or block the feed port 5, a return spring 11 is provided inside the upper working area to make the movable plate 8 have a tendency to move vertically upward, and then when the cam 7 drives the movable plate 8 to move downward, the return spring 11 will be compressed, and under the rotation of the cam 7, the return spring 11 can drive the movable plate 8 to move upward, that is, under the cooperation of the return spring 11, the movable plate 8 can drive the piston 6 to intermittently move vertically up and down, thereby realizing the opening or blocking of the feed port 5 by the piston 6.

[0028] As an implementation method in this embodiment, for the setting of the rotation of the cam 7, a second motor 12 can be fixedly arranged inside the upper working area, and the output shaft of the second motor 12 is connected to the cam 7 through a transmission belt 13. Then, when the second motor 12 is started, the output shaft of the second motor 12 can drive the cam 7 to rotate. Preferably, the second motor 12 can be set as a servo motor to meet corresponding usage requirements.

[0029] As an implementation method in this embodiment, Figure 1 and Figure 3 As shown, in order to prevent the flocculant from being deposited in the lower raw material area 4 and unable to move, a material guide platform 15 can be fixedly provided on the bottom inner wall of the lower raw material area 4 .

[0030] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
