[0002] Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. It is a hard glassy solid at room temperature. Its products include glue, latex, white powder, translucent beads and flakes. It has good thermal stability. It can be dissolved in water in any proportion, and the aqueous solution is a uniform and transparent liquid. After long-term storage, the viscosity of the solution will decrease due to the slow degradation of the polymer, especially when the storage and transportation conditions are poor. Polyacrylamide is widely used as a lubricant, suspending agent, clay stabilizer, oil displacement agent, fluid loss agent and thickener in drilling, acidizing, fracturing, water plugging, cementing, secondary oil recovery and tertiary oil recovery. It is an extremely important oilfield chemical.

[0022] Reference Figure 1-4 A feeding device for polyacrylamide flocculant comprises a prefabricated box 1, the side wall of the prefabricated box 1 is connected with a stable clamping mechanism, the clamping mechanism comprises two sleeve blocks 4 fixedly connected to the outer wall of the prefabricated box 1 and symmetrically arranged, a sleeve groove is arranged in the sleeve block 4, and an L-shaped clamping block 5 is slidably connected to the inner wall of the sleeve groove, a box cover 2 is arranged on the top of the prefabricated box 1, and a servo motor 3 is fixedly connected to the top of the box cover 2, wherein the working principle of the servo motor 3 is the existing technology, and no detailed description is made here;

[0023] The output end of the servo motor 3 is fixedly connected with an output shaft 6, and the outer side wall of the output shaft 6 located in the prefabricated box 1 is fixedly connected with multiple groups of first stirring blades 7. The output shaft 6 passes through the bottom of the prefabricated box 1 and is fixedly connected with a threaded rod 8. The threaded rod 8 is connected with a threaded sleeve 9. The outer side wall of the threaded rod 8 is provided with an external thread, and the threaded sleeve 9 is provided with a threaded opening. The inner side wall of the threaded opening is provided with an internal thread that matches the external thread. The inner side wall of the threaded opening is threadedly connected with the threaded rod 8, and the threaded sleeve 9 is threadedly sleeved with the threaded rod 8, so that when the threaded rod 8 rotates, the threaded sleeve 9 also rotates, thereby driving the second stirring blade 10 to rotate, and the polyacrylamide flocculant and the sewage are mixed;

[0024] A plurality of second stirring blades 10 are fixedly connected to the outer wall of the threaded sleeve 9, and the threaded sleeve 9 is connected to a material discharge mechanism, which includes a mounting cavity provided on the threaded sleeve 9, a driving motor 11 is fixedly connected to the inner wall of the mounting cavity, a rotating shaft 12 is fixedly connected to the output end of the driving motor 11, and the rotating shaft 12 passes through the mounting cavity and is fixedly connected to a storage barrel 13, wherein the material feeding of the storage barrel 13 is prior art and will not be described in detail herein, and a mounting ring 14 is rotatably connected to the outer wall of the storage barrel 13;

[0025] A first discharge port 15 is formed on the side wall of the storage barrel 13, and a second discharge port 16 corresponding to the first discharge port 15 is formed on the side wall of the mounting ring 14. A plurality of balls are arranged between the storage barrel 13 and the mounting ring 14, so that the storage barrel 13 can rotate better.

[0026] The specific working principle of the utility model is as follows:

[0027] In the initial state, the polyacrylamide flocculant is placed into the prefabricated box 1 from the box cover 2, and the L-shaped card block 5 is pulled out of the box 4 by using the sleeve block 4 in combination with the L-shaped card block 5. When it is pulled to a suitable position, the side wall of the sewage pool is clamped by the L-shaped card block 5, thereby achieving the fixation of the device;

[0028] At the same time, the servo motor 3 is started, and the servo motor 3 drives the output shaft 6 to rotate, and the rotation of the output shaft 6 drives the first stirring blade 7 to rotate, thereby fully stirring and crushing the polyacrylamide flocculant in the prefabricated box 1, thereby avoiding the phenomenon of agglomeration of the polyacrylamide flocculant;

[0029] The output shaft 6 rotates while driving the threaded rod 8 to rotate, and the threaded rod 8 rotates while driving the threaded sleeve 9 to rotate up and down, wherein the up and down movement of the threaded sleeve 9 drives the storage barrel 13 to move up and down, and the up and down movement of the storage barrel 13 realizes the discharge of materials from different water layers, thereby allowing the polyacrylamide flocculant to be combined with sewage from different water layers, and then the sewage from different water layers can be quickly cleaned and treated, which solves the problem in traditional devices that the polyacrylamide flocculant stays on the surface and needs additional stirring treatment to mix the polyacrylamide flocculant with the sewage, which is inefficient and prone to uneven mixing;

[0030] The driving motor 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 rotates the electric storage barrel 13. While the storage barrel 13 is rotating, when the first discharge port 15 on the storage barrel 13 rotates to the bottom and is aligned with the second discharge port 16 on the mounting ring 14, the polyacrylamide flocculant will be discharged from the first discharge port 15 and the second discharge port 16, wherein the amount of polyacrylamide flocculant discharged from the first discharge port 15 and the second discharge port 16 each time is the same, and the threaded sleeve 9 realizes its own rotation while moving up and down, and stirs the water layer where the threaded sleeve 9 is located, so that the sewage and the polyacrylamide flocculant are fully mixed, thereby improving the mixing efficiency.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
