Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4 , an additive storage device for oilfield chemistry, including a chemical storage barrel 1. Slide grooves 5 are opened on both sides inside the chemical storage barrel 1, and a protection component 7 is slidably connected inside the chemical storage barrel 1;

[0028] The protection component 7 includes a protection plate 71 slidably connected inside the chemical storage barrel 1. Slide plates 72 are fixedly connected to both the left and right sides of the protection plate 71. Clamping blocks 73 are fixedly connected to both the front and rear ends of the outer surface of the slide plates 72. A plurality of clamping grooves 6 with equal sizes and equally spaced distributions are opened at both the front and rear ends inside the slide grooves 5. The size of the clamping blocks 73 is adapted to the size of the clamping grooves 6;

[0029] A connection groove 10 is opened at the bottom of the protection plate 71, and an inhibition component 8 is clamped inside the connection groove 10;

[0030] The inhibition component 8 includes an inhibition plate 81 clamped inside the connection groove 10. Connection blocks 82 are fixedly connected to both the left and right sides of the inhibition plate 81. Grooves adapted to the size of the connection blocks 82 are opened on both the left and right sides inside the connection groove 10. An inhibitor is provided inside the inhibition plate 81.

[0031] By adopting the above technical solution, during use, rotate the protective plate 71 to drive the sliding plate 72 to rotate, and then use the sliding plate 72 to slide in the sliding groove 5. During the sliding process of the sliding plate 72, drive the protective plate 71 to slide, so as to meet the effect of adjusting the protective plate 71 at different positions. Then, put the chemical additive to be stored into the chemical storage barrel 1. According to the increase in the height of the input chemical additive, adjust the height of the protective plate 71. When the chemical additive is put in place, rotate the protective plate 71 to drive the sliding plate 72 to rotate, and at the same time use the clamping block 73 to be clamped into the clamping groove 6 to position the protective plate 71. After the protective plate 71 is positioned, use the inhibiting plate 81 to fit against the top of the chemical additive. An inhibitor for inhibiting the chemical reaction of the chemical additive is provided inside the inhibiting plate 81. It is clamped into the connecting groove 10 through the connecting block 82 to meet the effect of stably connecting the inhibiting plate 81 and the protective plate 71 directly and detaching and replacing the inhibiting plate 81. At the same time, it is avoided that during the storage of the chemical additive, due to the gap between the height and the chemical storage barrel 1, the chemical additive shakes during the movement process, resulting in a chemical reaction of the chemical additive and affecting the normal use of the chemical additive, which is beneficial to improving the safety and stability during the storage of the chemical additive.

[0032] Specifically, as Figure 4 shown, a connecting pipe 9 is fixedly connected to the top of the chemical storage barrel 1. A placement groove 4 is opened inside the connecting pipe 9. A limiting groove 3 is opened at the bottom of the inner side wall of the placement groove 4. A sealing assembly 2 is connected inside the placement groove 4;

[0033] The sealing assembly 2 includes a sealing cover 21 clamped inside the placement groove 4. A placement frame 22 is fixedly connected to the outer surface of the bottom of the sealing cover 21. The placement frame 22 is clamped inside the limiting groove 3;

[0034] A water-swellable water stop strip is arranged inside the placement frame 22, and connection holes are opened on the outer surface of the placement frame 22.

[0035] By adopting the above technical solution, the sealing cover 21 is snap-fitted to the top of the connecting pipe 9, and then the bottom of the sealing cover 21 is snap-fitted into the inner part of the placement groove 4. During the snap-fitting process of the sealing cover 21, the placement frame 22 is driven to be snap-fitted into the inner part of the limit groove 3. When the outside gas enters the inside of the chemical storage barrel 1 through the sealing cover 21 and the limit groove 3, the gas contacts the water-swellable water-stop arranged inside the limit groove 3 and inside the placement frame 22. The liquid in the gas causes the water-swellable water-stop to expand and then produces a sealing effect, thereby achieving a stable sealing for the limit groove 3 and avoiding the situation that the gas enters the inside of the chemical storage barrel 1 due to poor sealing effect and reacts with the chemical additives stored inside, resulting in waste of chemical additive resources. The settings of the sealing cover 21 and the placement frame 22 are used to achieve a multiple sealing effect, improving the safety during the storage process of the chemical storage barrel 1 and the stability of the chemical additives.

[0036] Working principle: During use, place the chemical additives to be stored into the inside of the chemical storage barrel 1. When placing the chemical additives, rotate the protection plate 71 to drive the sliding plate 72 to rotate, and turn out the snap-fitting block 73 from the inside of the snap-fitting groove 6. Then, put the chemical additives into the inner bottom of the chemical storage barrel 1. Slide the protection plate 71 according to the different heights of the placed chemical additives. After the chemical additives are added, rotate the protection plate 71 to reset, and at the same time drive the sliding plate 72 and the snap-fitting block 73 to reset. Use the snap-fitting block 73 to be snap-fitted into the inside of the snap-fitting groove 6 to meet the stability after the protection plate 71 is reset. The settings of the protection plate 71 and the suppression plate 81 are used to protect the top of the chemical additives.

[0037] Then press the sealing cover 21 to snap the sealing cover 21 into the placement groove 4 arranged inside the connecting pipe 9. At the same time, the placement frame 22 is snap-fitted into the inside of the limit groove 3, achieving a multiple sealing effect. A water-swellable water-stop strip is arranged inside the placement frame 22. When the outside gas contacts the water-swellable water-stop strip arranged inside the sealing cover 21 and the placement frame 22, the water-swellable water-stop strip expands to achieve a stable sealing effect, avoiding the situation that the gas flows into the inside of the chemical storage barrel 1 and reacts with the chemical additives, resulting in waste of chemical additive resources, which is beneficial to improving the stability and safety during the placement process of the chemical additives.

[0038] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
