[0002] Most of the crude oil in my country's oil fields has high wax content, high freezing point and high viscosity. Due to the high formation pressure and temperature in the far well area, paraffin is dissolved in the crude oil and the crude oil viscosity is low. When the crude oil flows into the near well area, due to the decrease in pressure and the decrease in the degassing temperature of the crude oil, the heavy components such as paraffin, colloid and asphalt in the crude oil will precipitate and adhere to the pore wall of the crude oil.

DETAILED DESCRIPTION
[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0048] A water-based wax crystal inhibiting wax inhibitor, comprising a sulfonate surfactant A, a sulfonate surfactant B, a maleate surfactant C and an ultra-low interfacial tension surfactant D, wherein the weight ratio of the sulfonate surfactant A: the sulfonate surfactant B: the maleate surfactant C: the ultra-low interfacial tension surfactant D is (8-23): (5-10): (3-5): (2-4), and the rest is water;
[0049] The sulfonate surfactant A is a branched alkyl sulfonic acid fatty amine salt;
[0050] The sulfonate surfactant B is sodium dodecylbenzene sulfonate;
[0051] The maleate surfactant C is isooctyl sulfosuccinate;
[0052] The ultra-low interfacial tension surfactant D is FS-3000 fluorocarbon surfactant.
[0053] The water-based wax crystal inhibition type paraffin inhibitor composed of this component can effectively prevent the precipitation and wax formation of wax crystals in oil well bores and oil pipelines, and at the same time can reduce the viscosity and pour point of crude oil, reduce the flow resistance of crude oil, and reduce the number of wax cleaning operations in oil well bores and oil pipelines; it has no flash point, no oxidants, and the construction process is safe; it has low corrosiveness and does not produce any sediment.
[0054] As a preferred embodiment of the present application, the weight percentage of the sulfonate surfactant A is 12.5%; the weight percentage of the sulfonate surfactant B is 5%; the weight percentage of the maleate surfactant C is 3%; the weight percentage of the ultra-low interfacial tension surfactant D is 4%; and the rest is water.
[0055] The overall performance of the wax inhibitor composed of material components under this formula is the best.
[0056] S1: At room temperature, inject a formulated amount of water into the reaction tank and turn on the stirrer for pre-stirring;
[0057] Room temperature adjustment can avoid solvent evaporation. Starting at a lower temperature can reduce water evaporation and ensure that the volume and concentration of the initial solution are stable.
[0058] The benefits of initial stirring: ensuring that the inner wall of the reaction tank and the agitator are fully wetted by water, reducing the possibility of subsequent solute adhesion, while providing a uniform initial environment.
[0059] S2: Control the temperature at 45 to 50°C, add one third of the formula amount of branched alkyl sulfonic acid fatty amine salt to the reaction tank in S1, and continue stirring until it is completely dissolved;
[0060] The benefits of controlling the temperature within 45 to 50°C: Appropriate temperature increase helps to increase the dissolution rate of the solute, ensuring that the branched alkyl sulfonic acid fatty amine salt can be dissolved quickly and evenly. At the same time, the fluidity of the solute is enhanced, reducing the agglomeration phenomenon caused by excessive local concentration, and promoting the performance of the finished wax inhibitor; uniform dissolution helps to form a stable wax inhibitor system, improving its dispersibility and anti-waxing effect in crude oil; when the temperature is lower than 45°C, the solute dissolution rate decreases, which may cause uneven distribution of the solute in the solution, and even the appearance of undissolved solid particles, affecting the subsequent steps and the performance of the final product. When the temperature is higher than 50°C, although high temperature helps the solute dissolve, too high temperature may accelerate the decomposition of the chemical substance or change its chemical properties, thereby affecting the overall effect of the wax inhibitor. In addition, too high temperature will also increase energy consumption and operating costs;
[0061] The batch addition of branched alkyl sulfonic acid fatty amine salt can alleviate the situation where the local concentration of the solution is too high, help the solute to dissolve more evenly, reduce agglomeration, and reduce the resistance during stirring.
[0062] S3: Control the temperature at 45 to 50° C., add the formulated amount of isooctyl succinate sulfonate to the reaction tank in S2, and continue stirring until it is completely dissolved;
[0063] The benefits of controlling the temperature within 45 to 50°C: adding auxiliary solutes at the same temperature can reduce the fluctuation of the solution temperature, which helps to maintain the stability and uniformity of the solution. At this temperature, the auxiliary solutes can better play their synergistic role with the main solute (i.e., branched alkyl sulfonic acid fatty amine salt), improve the overall performance of the wax inhibitor, and promote the performance of the finished wax inhibitor: enhance the surface activity of the wax inhibitor, further improve its permeability and anti-waxing effect in crude oil; when the temperature is lower than 45°C, it may cause uneven mixing with the main solute, affecting the performance of the wax inhibitor; when the temperature is higher than 50°C, although high temperature helps the solute to dissolve, too high temperature may accelerate the decomposition of the chemical substance or change its chemical properties, thereby affecting the overall effect of the wax inhibitor. In addition, too high temperature will also increase energy consumption and operating costs;
[0064] At this point, the solution already has a certain surface activity, and adding auxiliary solutes can further improve the wettability and stability of the solution, laying a good foundation for the subsequent mixing process.
[0065] S4: Add one third of the formula amount of branched alkyl sulfonic acid fatty amine salt to the reaction tank in S3 at a temperature of 55 to 60° C. and stir until completely dissolved;
[0066] The benefits of controlling the temperature within 55 to 60°C: Higher temperatures can further accelerate the dissolution process of the solute, especially when the addition amount is large. At higher temperatures, the convection and diffusion of the solution are enhanced, which helps to evenly distribute the solute in the solution; it promotes the performance of the finished wax inhibitor: it increases the effective concentration of the wax inhibitor in crude oil and improves its stability under low temperature conditions, thereby more effectively reducing the viscosity and freezing point of the crude oil; when the temperature is lower than 55°C, the dissolution rate is further reduced, which may cause the solute to form local high concentration areas in the solution, and even agglomeration, affecting the uniformity and stability of the wax inhibitor; when the temperature is higher than 60°C, the high temperature may accelerate the thermal motion of the solute molecules, resulting in intensified intermolecular collisions in the solution, thereby triggering unnecessary chemical reactions or phase separation, affecting the performance and stability of the wax inhibitor.
[0067] By adding branched alkyl sulfonic acid fatty amine salt in batches, the concentration change of the solution can be better controlled to ensure that the solute added each time can be fully dissolved and fully mixed with the previous solution, thereby improving the overall uniformity.
[0068] S5: Control the temperature at 55 to 60°C, add the formulated amount of FS-3000 fluorocarbon surfactant to the reaction tank in S4, and continue stirring until it is evenly dispersed;
[0069] Benefits of temperature control within 55 to 60°C: FS-3000 fluorocarbon surfactant can fully demonstrate its excellent surface activity at high temperature, which helps to form a stable emulsion or dispersion system; the thermal motion of molecules at high temperature intensifies, which helps to evenly disperse FS-3000 in the solution and improve its interaction ability with crude oil; it promotes the performance of the finished wax inhibitor: it significantly improves the adsorption capacity of the wax inhibitor on the surface of crude oil, forms a dense protective film, and effectively prevents the deposition of wax crystals and the condensation of crude oil; when the temperature is lower than 55°C, the surface activity of FS-3000 fluorocarbon surfactant may not be fully exerted, resulting in reduced dispersibility and stability in the solution, which in turn affects the overall effect of the wax inhibitor; when the temperature is higher than 60°C, the high temperature may cause FS-3000 fluorocarbon surfactant to decompose or react with other chemicals unnecessarily, thereby changing its chemical properties and reducing its surface activity, which in turn affects the wax prevention and viscosity reduction effects of the wax inhibitor;
[0070] FS-3000 fluorocarbon surfactant has special surface activity and wetting properties. Adding it at this time can more effectively improve the surface tension of the solution and promote the dissolution and dispersion of subsequent solutes.
[0071] S6: Control the temperature at 55 to 60° C., add the remaining branched alkylsulfonic acid fatty amine salt and the formulated amount of sodium dodecylbenzenesulfonate to the reaction tank in S5, and continue stirring until completely dissolved and evenly mixed;
[0072] The benefits of controlling the temperature within 55 to 60°C: All solutes are added and mixed at a higher temperature to ensure that all solutes can be fully dissolved and reach the predetermined concentration. Through sufficient mixing and dissolution, a uniform and stable paraffin inhibitor system is formed to maximize its effect of preventing wax deposition, reducing crude oil viscosity and freezing point, and reducing crude oil flow resistance. At the same time, a uniform solution system also helps the uniform distribution and long-lasting effect of the paraffin inhibitor in crude oil;
[0073] In this step, all the remaining solutes are added at once, which can save time and operation steps. Due to the sufficient preparation and dissolution in the previous steps, the solution at this time already has good solubility and dispersion ability, and can quickly accept and dissolve the remaining solutes, thereby ensuring the uniformity and performance of the final product.
[0074] In the above preparation process, the main solute is added in three stages. By first adding one-third of the branched alkyl sulfonic acid fatty amine salt and stirring until it is basically dissolved, the basic system of the wax inhibitor can be initially formed. This step provides a stable solution environment for the subsequent addition of other auxiliary solutes and surfactants; adding again: continuing to add the branched alkyl sulfonic acid fatty amine salt after adding the auxiliary solute can further increase the solute concentration and promote its interaction with the auxiliary solute. This step helps to improve the surface activity and penetration ability of the wax inhibitor; adding finally: adding the remaining branched alkyl sulfonic acid fatty amine salt together with other remaining solutes and mixing evenly to improve work efficiency and ensure that all solutes are fully dissolved and reach a predetermined concentration.
[0075] In summary, the addition of the main solute branched alkyl sulfonic acid fatty amine salt in three steps is based on considerations such as improving dissolution uniformity, promoting mixing effect and optimizing product quality. This step-by-step addition method is helpful to prepare a water-based wax crystal inhibition type wax inhibitor product with excellent performance, stability and reliability. Embodiment 1:
[0076] The dosage of water-based wax crystal inhibition type wax inhibitor is 15 tons, and the dosage concentration is 0.25%.
[0077] The weight percentage composition of the water-based wax crystal inhibitor is as follows: 12.5% sulfonate surfactant A, 5% sulfonate surfactant B, 3% maleate surfactant C, 4% ultra-low interfacial tension surfactant D, and the rest is water. Embodiment 2:

[0082] The effects of Examples 1 to 3 are shown in the table below.
[0083]
[0084] It can be seen from the above table that after the water-based wax crystal inhibiting paraffin inhibitor was added to the three high-wax oil wells, the viscosity, crude oil pour point and wax deposition amount were significantly reduced, and the paraffin prevention rate could reach more than 70%, which is better than the standard requirement value of the oil-based wax crystal inhibiting paraffin inhibitor of ≥30% in the petroleum and natural gas industry standard "SYT6300-2009 Technical Requirements for Wax Removers and Paraffin Inhibitors for Oil Production", and its viscosity reduction rate is also better than the viscosity reduction rate mentioned in the industry standard.

[0086] A mounting ring 9 and a transmission gear 16 are installed on the top of the inner cavity of the reaction tank 1. A swivel ring 8 is fixed to the lower end of the mounting ring 9, and the lower end of the swivel ring 8 is connected to a gear ring 44 through a plurality of connecting rods 7. The gear ring 44 is gear-engaged with the gear on the output shaft of the drive motor 15. The drive motor 15 is connected to the top of the inner cavity of the reaction tank 1 through a mounting plate 14. A second arc plate 11 is fixed on the outer wall of the gear ring 44. A first arc plate 10 is installed on the connecting rod 7. The first arc plate 10 is provided with a group of tooth segments 12. Two groups of tooth segments 12 are arranged at intervals on the second arc plate 11. The tooth segment 12 includes a first tooth connection portion and a second tooth connection portion. A blank section 13 is arranged between the first tooth connection portion and the second tooth connection portion. The transmission gear 16 is gear-engaged with the corresponding drive gear 19 on the first storage bin 3.
[0087] Before use, the first storage bin 3, the second storage bin 4, the third storage bin 5, and the fourth storage bin 6 are respectively filled with branched alkyl sulfonic acid fatty amine salt (powder), succinic acid isooctyl ester sulfonate (powder), FS-3000 fluorocarbon surfactant (liquid) and sodium dodecylbenzene sulfonate (powder). When in use, the drive motor 15 can be controlled to work, and the drive motor 15 can drive the gear ring 44 to rotate clockwise, and the clockwise rotation of the gear ring 44 can drive the first arc plate 10 with the tooth segment 12 and the second arc plate 11 to rotate clockwise. When the second arc plate 11 rotates, it will The driving gear 19 corresponding to the first storage bin 3 is geared and drives the metering cylinder 18 to rotate. In the initial state, the metering cavity 20 of the metering cylinder 18 opens upward and is consistent with the unloading opening of the storage bin. The metering cavity 20 is filled with material.

When the branched alkyl sulfonic acid fatty amine salt needs to be added later, the gear ring 44 stops rotating. The ring 44 continues to rotate, at which time the first arc plate 10 is gear-engaged with the transmission gear 16 and drives the metering cylinder 18 to rotate through the driving gear 19 to deliver the material into the reaction tank 1. Subsequently, as the gear ring 44 continues to rotate, the second arc plate 11 can drive the metering cylinder 18 on the third storage bin 5 to rotate for unloading, and through the cooperation of the first arc plate 10 and the second arc plate 11, the branched alkyl sulfonic acid fatty amine salt and sodium dodecylbenzene sulfonate are unloaded at the same time. The reaction tank 1 only uses one set of motors to drive the materials to be unloaded in an orderly and quantitative manner, and the structure is simple and stable, and the cost is low.
[0088] It should be noted that: 1. The reaction tank 1 is provided with a feed pipe and a discharge pipe, through which water can be added to the reaction tank 1, and the mixed anti-wax agent can be discharged through the discharge pipe; 2. All electrical devices on the reaction tank 1 are electrically connected to the controller; 3. An elastic cushion layer is provided on the outer wall of the metering cylinder 18, which is in close contact with the inner wall of the mounting frame 17 to form a seal, and the tooth-connected and separated metering cylinder 18 can be positioned by the elastic cushion layer; 4. The transmission gear 16 is located above the drive gear 19, and the heights of the drive gears 19 are consistent, so that the second arc plate 11 can be toothed with each drive gear 19, and the first arc plate 10 can be prevented from being toothed with the drive gear 19; 5. The blank section 13 is provided to provide a residence time for the metering cavity 20 with the opening facing downward, which is conducive to the complete discharge of the material in the metering cavity 20; 6. The quantitative cavity 20 of the metering cylinder 18 corresponding to each storage bin has a different capacity, and its capacity is the required addition amount of each material in the above process.
[0089] As a preferred embodiment of the present application, it also includes a feeding unit, one end of which is arranged on the metering cylinder 18, and the other end extends to the outside of the metering cylinder 18, for promoting the discharge of materials in the first storage bin 3, the second storage bin 4 and the fourth storage bin 6 into the metering chamber 20, and at the same time helps to discharge the materials in the metering chamber 20.
[0090] As a preferred implementation in this application, Figure 3 , Figure 5 and Figure 7 As shown, the unloading unit includes a rectangular plate 21, a receiving groove, a top block 23, an air outlet pipe 26, a first L-shaped rotating shaft 30 and a second L-shaped rotating shaft 32;
[0091] The rectangular plate 21 is sealed and slidably disposed in the quantitative chamber 20, and the lower end of the rectangular plate 21 is connected to the inner wall of the bottom of the quantitative chamber 20 via a first pull rope 24;
[0092] An elastic airbag 22 is arranged in the inner cavity of the receiving groove, and the inner cavity of the elastic airbag 22 is communicated with the ventilation flow channel 25, and the ventilation flow channel 25 is connected with the air outlet end and the air inlet end of the air outlet pipe 26, and the air outlet pipe 26 is arranged at the axis center of the mounting shaft of the quantitative cylinder 18, and the air outlet pipe 26 penetrates the mounting frame 17 and passes through the rotary joint 27 and the piston cylinder 28, and a rack 29 is installed on the piston that is sealed and slidably arranged in the inner cavity of the piston cylinder 28, and the upper end of the rack 29 slides through the top of the inner cavity of the reaction tank 1;
[0093] The first L-shaped rotating shaft 30 is rotatably arranged on the outer wall of the storage bin, and a one-way gear 31 is installed on the first L-shaped rotating shaft 30, and the one-way gear 31 is gear-connected with the rack 29;
[0094] The second L-shaped rotating shaft 32 is rotatably set at the upper end of the installation frame 17, and multiple impact hammers 33 are installed on the second L-shaped rotating shaft 32. The contact rod of the second L-shaped rotating shaft 32 is located directly below the contact rod of the first L-shaped rotating shaft 30, and a contact roller 35 is set on the end of the contact rod of the first L-shaped rotating shaft 30.
[0095] When the metering cylinder 18 filled with materials is rotated, the feed opening of the metering chamber 20 is facing upwards at the beginning, and as the metering cylinder 18 rotates, the feed opening of the metering chamber 20 can be set downwards (the metering cylinder 18 needs to stay for a period of time at this time, and this stay time provides enough time for the subsequent pushing movement of the rectangular plate 21). At this time, the rectangular plate 21 moves downwards by gravity, pushing the materials out (because of the gravity of the accumulated materials in the storage bin, the materials in the metering chamber 20 will be squeezed during loading, which may easily cause some materials to clump or form a whole and cannot fall into the reaction tank 1 by their own gravity) and the metering chamber 20 is filled with materials. The material on the inside of the cavity 20 is scraped off and pushed out. When the rectangular plate 21 pushes all the materials out of the quantitative cavity 20, it will not be able to move downward due to the pulling force of the first pull rope 24. At this time, the rectangular plate 21 is still in the inner cavity of the quantitative cavity 20. With the rotation of the quantitative cylinder 18, the rectangular plate 21 will tilt and slowly move downward, and finally the weight of the rectangular plate 21 acts on the elastic airbag 22 through the top block 23. The elastic airbag 22 is squeezed, and the internal gas enters the piston cylinder 28 through the ventilation flow channel 25 and lifts the rack 29. As the rack 29 is lifted, the rack 29 will drive the first L-shaped rotating The shaft 30 rotates counterclockwise, and contacts and squeezes the contact rod on the second L-shaped shaft 32 through the contact roller 35 on the contact rod, so that the impact hammer 33 rotates away from the storage bin. When the contact rod of the first L-shaped shaft 30 and the contact rod of the second L-shaped shaft 32 are vertical, as the first L-shaped shaft 30 rotates, the air pressure will cause the first L-shaped shaft 30 to quickly contact and separate from the second L-shaped shaft 32 and return to its original position. At this time, the impact hammer 33 moves closer to the storage bin through the action of gravity, and finally collides with the outer wall of the storage bin, which is conducive to vibrating the material in the storage bin into the quantitative cavity 20. At the same time, when the impact hammer 33 is hit, it will move a small distance away from the storage bin due to the reaction force, and then collide with the storage bin again. This process is repeated, and multiple impacts can be formed on the storage bin, which is further conducive to vibrating the material in the storage bin into the quantitative chamber 20. After the loading is completed, the quantitative cylinder 18 rotates, the feed opening of the quantitative chamber 20 faces downward and the rectangular plate 21 moves downward, the extrusion force acting on the elastic airbag 22 is released, and the rack 29 moves downward to return to its original position. At the same time, the first L-shaped shaft 30 does not rotate. This unloading unit can automatically promote the unloading of the storage bin and the quantitative cylinder 18.
[0096] It should be noted that, first, a stopper 34 is installed on the rack 29. When the first L-shaped rotating shaft 30 is quickly restored to its original position, the rack 29 is limited by the blocking of the stopper 34 and the top of the reaction tank 1 to prevent it from excessive movement; second, an elastic damping sleeve is provided at the rotation connection between the first L-shaped rotating shaft 30 and the storage bin, and the inner wall of the elastic damping sleeve is in close contact with the outer wall of the first L-shaped rotating shaft 30, which can ensure that the first L-shaped rotating shaft 30 does not rotate in the absence of external force.
[0097] As a preferred embodiment of the present application, it also includes an accelerating impact unit, which is arranged in the inner cavity of the metering cylinder 18, and is used to increase the speed when the top block 23 collides with the elastic airbag 22, thereby causing the impact hammer 33 to form a more violent collision with the storage bin.
[0098] As a preferred implementation in this application, Figure 5 and Figure 6 As shown, the acceleration impact unit includes a trapezoidal movable block 36, a second pull rope 39, a return spring 37, a weight 42, a second partition plate 40 and a magnetic tube 41;
[0099] The trapezoidal movable block 36 is sealingly slidably arranged in the inner cavity of the metering cylinder 18, the two ends of the return spring 37 are respectively connected to the first partition 38 and the trapezoidal movable block 36, one end of the second pull rope 39 is connected to the trapezoidal movable block 36, and the other end of the second pull rope 39 passes through the first partition 38 and the second partition 40 and is connected to the weight 42.
[0100] like Figure 5 At this time, the return spring 37 is in a compressed state, and the second pull rope 39 is in a taut state. When the feed port opening of the quantitative chamber 20 rotates to face downward, during this process, the weight 42 will move closer to the return spring 37 due to gravity (in this process, the iron weight 42 will pass through the magnetic tube 41, and the internal magnetic field will hinder the movement of the weight 42). At this time, the return spring 37 will return to its original position, and the end of the trapezoidal movable block 36 will extend into the quantitative chamber 20. When the rectangular plate 21 moves downward, it will be squeezed with the inclined surface of the trapezoidal movable block 36 and finally move to the bottom of the trapezoidal movable block 36, and the trapezoidal movable block 36 will press the rectangular plate 2 1 forms a blockage, and the metering cylinder 18 continues to rotate. When the metering chamber 20 rotates to the opening facing upward, the weight 42 still moves in the magnetic tube 41 due to gravity. After moving for a period of time, the weight 42 moves out of the magnetic tube 41. At this time, the second pull rope 39 is straightened and pulls the trapezoidal movable block 36 to squeeze the reset spring 37, and finally releases the blockage of the rectangular plate 21. At this time, the rectangular plate 21 accelerates downward under the action of gravity and forms a fierce collision with the elastic airbag 22, which can finally make the second L-shaped shaft 32 subject to a large rotation thrust, so that the impact hammer 33 can rotate at a larger angle, and have a better impact effect on the storage bin.
[0101] It should be noted that: first, a magnetic isolation groove 46 can be set at the bottom of the inner cavity of the quantitative cavity 20, and a permanent magnet 45 can be set in the magnetic isolation groove 46. The magnetic effect of the permanent magnet 45 and the rectangular plate 21 can further accelerate the downward movement of the rectangular plate 21, further increasing the subsequent impact effect on the storage bin. At the same time, the magnetic attraction force generated is smaller than the gravity of the rectangular plate 21, preventing the rectangular plate 21 from being unable to move downward by its own gravity when the feed opening of the quantitative cavity 20 is facing downward; second, when the rectangular plate 21 moves downward, it will be squeezed and contacted with the trapezoidal movable block 36, that is, it will collide with the trapezoidal movable block 36, which is conducive to the falling of dust on the rectangular plate 21; third, the outer surface of the trapezoidal movable block 36 is provided with an elastic sealing layer; fourth, before the rectangular plate 21 collides with the elastic airbag 22, the feed opening of the quantitative cavity 20 of the rectangular plate 21 is aligned with the unloading opening of the storage bin, and after alignment, the impact hammer 33 is used to impact, which is more conducive to the falling of the material in the storage bin and filling the quantitative cavity 20.
[0102] As a preferred embodiment of the present application, it also includes an anti-extrusion unit, which is arranged in the inner cavity of the metering cylinder 18. When the metering cylinder 18 rotates and the feed opening of the metering cavity 20 is blocked by the inner wall of the mounting frame 17, the rectangular plate 21 is prevented from moving so that the powder material is squeezed into blocks between the inner wall of the mounting frame 17 and the rectangular plate 21.
[0103] When the metering cylinder 18 filled with materials rotates, in order to prevent the rectangular plate 21 from moving during the rotation process, the movement of the rectangular plate 21 will cause its weight to act on the material, squeezing the material, and easily squeezing the material into blocks or forming a whole. After the block material falls into the reaction tank 1, the contact area with the solution is reduced and it is easy to form a clumping, which makes it impossible to achieve rapid dissolution of the material, so an anti-extrusion unit is provided.
[0104] As a preferred implementation in this application, Figure 5 and Figure 6 As shown, the anti-extrusion unit includes all structures of the acceleration impact unit, and the anti-extrusion unit also includes a positioning plate 43 with positioning holes.
[0105] like Figure 5As shown, in the anti-extrusion unit (the structures appearing below are all structures in the anti-extrusion unit), when the opening of the quantitative chamber 20 is facing upward, its reset spring 37 is in a natural state, and the end of the trapezoidal movable block 36 is located in the positioning hole of the positioning plate 43, limiting the rectangular plate 21. When the quantitative cylinder 18 is rotated to the point where the feed opening is facing downward, the weight 42 is still moving in the magnetic tube 41 due to gravity. After moving for a period of time, the weight 42 moves out of the magnetic tube 41, and causes the second pull rope 39 to drive the trapezoidal movable block 36 to squeeze the reset spring 37, that is, the trapezoidal movable block 36 moves toward the inner cavity of the quantitative cylinder 18, and finally causes the end of the trapezoidal movable block 36 to move out of the positioning hole. At this time, the rectangular plate 21 moves downward to perform a scraping operation, and continues to rotate to restore the quantitative cylinder 18 to its original position, and finally causes the end of the trapezoidal movable block 36 to be plugged into the positioning hole.
[0106] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
