DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Referring to Figures 1-4 A quantitative filling device of oilfield neutral scale cleaning and preventing agent, including base 1, the upper surface of base 1 is fixedly connected with a plurality of support rods 2, the upper end of a plurality of support rods 2 is fixedly connected with the same storage tank 3, the upper surface of storage tank 3 is fixedly connected with storage cover 4, the lower surface of storage cover 4 is equipped with anti-solid component, the middle end of base 1 upper surface is fixedly connected with mounting frame 5, the inside of mounting frame 5 is fixedly connected with tee pipe 6, the inlet end of tee pipe 6 is fixedly connected with filling assembly, the upper end of the surface of storage tank 3 is fixedly connected with feeding opening 7, the upper end of feeding opening 7 is hinged with sealing cover 8 through hinge.

[0023] In the utility model, the anti-solid component includes rotating rod 9 that is rotatably connected to the lower surface of storage cover 4, a plurality of stirring rods 10 are fixedly connected to the surface of rotating rod 9, the upper surface of storage cover 4 is fixedly connected with drive motor 11, the power end of drive motor 11 is fixedly connected to rotating rod 9, and drive motor 11 drives rotating rod 9 and stirring rod 10 to rotate, and the rotation of stirring rod 10 can avoid the solidification of scale cleaning agent in storage tank 3.

[0024] The filling assembly comprises a piston cylinder 12 fixedly connected to the inlet end of the tee pipe 6, a filling piston 13 movably connected inside the piston cylinder 12, a fixed plate 14 fixedly connected to the upper surface of the base 1, an electric push rod 15 fixedly connected to one side of the fixed plate 14, the telescopic end of the electric push rod 15 being fixedly connected to the filling piston 13, a first one-way valve 16 fixedly connected to the upper end of the tee pipe 6, the upper end of the first one-way valve 16 being fixedly connected to the storage tank 3, a second one-way valve 17 fixedly connected to the lower end of the tee pipe 6, the lower end of the second one-way valve 17 being fixedly connected to a filling pipe 18, and a valve 19 arranged on the surface of the filling pipe 18. When the electric push rod 15 is activated, it drives the filling piston 13 to move linearly in the piston cylinder 12. During this process, the position change of the filling piston 13 produces different fluid dynamics effects. Specifically, when the filling piston 13 moves outward of the piston cylinder 12 (i.e. in the opposite direction of the tee pipe 6), a low-pressure area is formed, thereby generating suction. This suction effect will draw the antifouling agent in the storage tank 3 through the first one-way valve 16 and guide it into the tee pipe 6. At this time, the first one-way valve 16 ensures that the antifouling agent can only flow in one direction, preventing it from flowing back to the storage tank 3. Subsequently, when the filling piston 13 changes direction and moves inward of the piston cylinder 12 (i.e. in the direction of the filling point), it compresses the space inside the piston cylinder 12, thereby generating high pressure in the tee pipe 6. This pressure pushes the antifouling agent through the second one-way valve 17, making it flow in one direction into the filling pipe 18 and eventually be injected into the target location. Similarly, the arrangement of the second one-way valve 17 ensures that the antifouling agent can only flow in one direction from top to bottom (i.e. from the tee pipe 6 to the filling pipe 18), avoiding any possible backflow.

[0025] The lower surface of the base 1 is fixedly connected to a plurality of moving wheels 20, the number of which is four. The arrangement of the moving wheels 20 allows the device to be easily moved to the location where filling is required, improving the flexibility of the device when in use.

[0026] The utility model discloses when using, first open the sealing cover 8 and add antifouling agent to the storage tank 3 through the charging port 7, after adding, close the sealing cover 8 and start drive motor 11 and drive rotating rod 9 and stirring rod 10 rotation, avoid antifouling agent solidification in the storage tank 3, then through the moving wheel 20 and push the device to the place that needs to fill, connect the filling pipe 18 to target point and open the valve 19, start electric push rod 15 and drive filling piston 13 to move to piston cylinder 12, and when filling piston 13 moves to the outside of piston cylinder 12, will produce suction force and suck antifouling agent from the storage tank 3 to the tee pipe 6 through the first check valve 16, and when filling piston 13 moves to the inside of piston cylinder 12, will produce the thrust and push antifouling agent in the tee pipe 6 to the filling pipe 18 through the second check valve 17, the setting of first check valve 16 and second check valve 17 lets antifouling agent only move from top to bottom, finally antifouling agent passes through the filling pipe 18 and enters target point, and the fixed movement path of filling piston 13 ensures that the dose of antifouling agent can keep consistent in every filling process, to realize accurate quantitative filling.

[0027] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed by the utility model, according to the technical scheme of the utility model and the utility model concept, carries out equivalent replacement or change, should be covered in the protection scope of the utility model.
