[0009] Preferably, the material of the wax-removing ball body is ethylene vinyl acetate, which can be dissolved in crude oil environment.

[0010] Preferably, the water-soluble plastic film is made of polyvinyl alcohol plastic film, whose molecular chain contains a large number of hydroxyl groups -OH, which has strong hydrophilicity, and the water-soluble plastic film is located 10 mm away from one end of the through hole.

[0011] Preferably, the chemical cleaning agent contains kerosene, aromatic hydrocarbons, sodium alkyl sulfonate, ethylene-vinyl acetate copolymer, dispersant, and stabilizer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The main body of the wax-removing ball in this utility model is made of ethylene vinyl acetate, which can dissolve in the crude oil environment. After 24 hours of use, the wax-removing ball body will automatically dissolve in the oil pipe, thereby avoiding oil pipe blockage and eliminating the need for searching, making the wax-removing ball more convenient to use.

[0014] 2. In this utility model, the interior of the wax cleaning ball body is provided with a storage tank for storing chemical cleaning agent. When the wax cleaning ball is used in the oil pipe, the internal liquid and pressure cause the water-soluble plastic film to melt and rupture, thereby allowing the stored chemical cleaning agent inside the storage tank to be discharged to the outside through the through hole, further increasing the effectiveness of the wax cleaning ball.

[0023] Please see Figure 1 and Figure 4 A water-soluble wax cleaning ball includes: a wax cleaning ball body 1 and a cleaning agent storage component. The cleaning agent storage component is installed inside the wax cleaning ball body 1. The cleaning agent storage component includes a storage tank 7, a through hole 2, a chemical cleaning agent 4, and a water-soluble plastic film 3. The storage tank 7 is opened inside the wax cleaning ball body 1 and is filled with the chemical cleaning agent 4. Multiple through holes 2 are opened on the outer side of the wax cleaning ball body 1 and penetrate the inner wall of the storage tank 7. A water-soluble plastic film 3 is installed on the inner side of one end of the through hole 2. Multiple cleaning protrusions 5 are installed on the outer side of the wax cleaning ball body 1, and a conical cleaning block 6 is installed on the outer side of the cleaning protrusions 5.

[0024] The dewaxing ball body 1 is used to clean the inside of the oil pipe. It is pushed inwards under pressure, and the outer cleaning protrusions 5 and conical cleaning blocks 6 rub against the pipe wall to clean it. The dewaxing ball body 1 is made of ethylene vinyl acetate, which is soluble in crude oil. After 24 hours of use, the dewaxing ball body 1 automatically dissolves in the oil pipe, preventing blockages and eliminating the need for searching, making it more convenient to use. The dewaxing ball body 1 has an internal storage tank 7 for storing chemical cleaning agent 4. When the dewaxing ball is used in the oil pipe, the internal liquid and pressure cause the water-soluble plastic film to... The membrane 3 melts and ruptures, allowing the stored chemical cleaning agent 4 inside the storage tank 7 to be discharged to the outside through the through hole 2, further enhancing the effectiveness of the wax cleaning ball. The water-soluble plastic film 3 is made of polyvinyl alcohol plastic film, whose molecular chain contains a large number of hydroxyl groups -OH, making it highly hydrophilic. The water-soluble plastic film 3 is located 10mm away from one end of the through hole 2, preventing friction between the wax cleaning ball body 1 and the water-soluble plastic film 3, which could cause the water-soluble plastic film 3 to rupture. The chemical cleaning agent 4 contains kerosene, aromatic hydrocarbons, sodium alkyl sulfonate, ethylene-vinyl acetate copolymer, dispersant, and stabilizer.

[0025] Working principle: First, the wax removal ball body 1 is inserted into the oil pipe through the ball launcher. The internal fluid pressure pushes the wax removal ball body 1 to move in the oil pipe, so that the cleaning protrusions 5 and conical cleaning blocks 6 on the outside clean the pipe wall. At this time, the water-soluble plastic film 3 breaks and melts, so that the chemical cleaning agent 4 inside the storage tank 7 is discharged to the outside through the through hole 2. Under the action of the chemical cleaning agent 4, the oil pipe is cleaned more thoroughly. After 24 hours of use, the wax removal ball body 1 automatically dissolves inside the pipe.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
