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.

[0020] This utility model provides, for example Figures 1-4The illustrated oilfield chemical dissolving and mixing device includes a conical cylinder 1, inside which a stirring mechanism is installed. The conical cylinder 1 is shaped like a frustum, wider at the top and narrower at the bottom. A circular cylinder 8 is fixedly connected to the bottom of the conical cylinder 1, and a sealing cover 9 is movably connected to the bottom of the circular cylinder 8. A homogenizing dissolving mechanism is installed inside the circular cylinder 8, including a spiral auger 15. The spiral auger 15 is located at the bottom of the conical cylinder 1 and is used to re-stir undissolved sediment. The frustum shape allows the sediment to enter the homogenizing dissolving mechanism. During the operation of the equipment, the stirring mechanism mixes and stirs different raw materials. During the stirring process, incompletely reacted chemicals deposit and accumulate at the bottom of the equipment. At this time, the spiral auger 15 reverses its direction, sending the sediment deposited in the circular cylinder 8 out of the circular cylinder 8, and cooperating with the stirring mechanism to re-stir the sediment, thus reducing incomplete reactions and material waste.

A circular rod 12 is fixedly connected to the side of the stirring blade 11 away from the inner wall of the conical cylinder 1. The driving assembly includes a motor 13 fixedly connected to the top of the conical cylinder 1. A rotating shaft 10 is fixedly connected to the output shaft of the motor 13. The rotating shaft 10 is fixedly connected to the end of the circular rod 12 away from the stirring blade 11. The bottom of the rotating shaft 10 is fixedly connected to the top of the auger rod 15. The stirring mechanism uses the reverse rotation of the stirring blade 11 to form an upward vortex, so that chemical raw materials of different densities are evenly mixed, thereby improving the reaction efficiency. The side wall of the stirring blade 11 and the inner wall of the conical cylinder 1 are in contact. After the mixing and stirring work is completed, the motor 13 is reversed to add clean water into the conical cylinder 1. The unreacted sludge falls into the circular cylinder 8. The sealing cover 9 is opened, and the auger rod 15 is reversed to discharge the sludge and chemical residues from the conical cylinder 1, thereby achieving a cleaning effect and preventing residual chemicals from affecting the next mixing and stirring work.

[0023] Preferably, the outer wall of the conical cylinder 1 is provided with a discharge mechanism, which is used to discharge the mixed chemicals at a uniform speed. The discharge mechanism includes a first water pipe 7 fixed to the outer wall of the discharge port 14. The first water pipe 7 is fixedly connected to a second water pump 6.

The first water pump 3 adds a certain proportion of chemical raw materials to the conical cylinder 1 through the three-way valve 5 and flow meter 4. The motor 13 drives the circular rod 12 and stirring blade 11 to rotate synchronously through the rotating shaft 10. The stirring blade 11 forms an upward vortex, achieving the effect of uniformly stirring the chemicals. At the same time, the rotating shaft 10 drives the auger rod 15 to rotate, and the auger rod 15 sends the sediment in the circular cylinder 8 into the conical cylinder 1 for re-stirring. After stirring is completed, the motor 13 is reversed, clean water is added to the conical cylinder 1, the sealing cover 9 is opened, and the auger rod 15 discharges the unreactable sediment deposited in the circular cylinder 8, achieving an automatic cleaning effect.
