Technical Field
[0001] This utility model relates to auxiliary devices for acidification in the petroleum industry, and in particular to an environmentally friendly ton-bucket mixing device for mixing acidic additives. Background Technology
[0002] Acidification operations require the use of various liquid additives, and the correct selection of the acid solution is crucial for successful matrix acidification. The additives serve to prevent excessive corrosion, prevent the formation of acid sludge and emulsification, prevent iron precipitation, aid in discharge, increase the effective range of the acid solution, and prevent the precipitation of reaction products. Some additive formulations contain highly corrosive components such as hydrochloric acid. If large-capacity enamel-lined stirred reactors are used for long-term production of these additives in a workshop, the hydrochloric acid will corrode the discharge port of the enamel-lined stirrer, and the volatilized hydrochloric acid gas will cause long-term and irreversible corrosion to other equipment in the workshop. This not only damages equipment but may also lead to production safety hazards. Therefore, appropriate protective measures and equipment maintenance strategies should be adopted during operation.
[0003] In existing technologies, the impellers of agitators have been optimized to improve their performance, and effective defoaming treatment has also been performed on the materials. However, some challenges remain when handling additives containing highly corrosive components such as hydrochloric acid. Specifically, the corrosiveness of hydrochloric acid can cause significant damage to the agitator impellers, accelerating their wear and corrosion. Furthermore, the volatilization of hydrochloric acid gas not only corrodes the equipment but also pollutes the environment. To address these problems, this invention designs an environmentally friendly ton-bucket agitator for mixing acidic additives. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned deficiencies in the existing technology by providing an environmentally friendly ton-barrel mixing device for mixing acidic additives.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0021] Example 1, referring to Figure 1 This utility model discloses an environmentally friendly ton-bucket mixing device for mixing acidic additives, comprising a device body 1, a controller 2, a delivery pump 3, a transmission mechanism 4, a ton-bucket 9, a fan 10, a gas purification bag 11, a first raw material tank 14, and a second raw material tank 15. The transmission mechanism 4 is installed at the upper end of the device body 1, and a stirring component is provided at the lower end of the transmission mechanism 4. The ton-bucket 9 is placed inside the device body 1, and the stirring component extends into the ton-bucket 9. The fan 10 and the gas purification bag 11 are provided on both sides of the upper end of the device body 1. An air outlet 16 is provided on one side of the lower end of the device body 1, and the air outlet 16 is connected to an external gas recovery device. The first raw material tank 14 and the second raw material tank 15 are connected to the outside of the device body 1 through the delivery pump 3. The device body 1 is electrically connected to the controller 2.
[0022] The stirring assembly includes a stirring rod 6 and a stirring blade 13. The stirring blade 13 is fixedly mounted on the bottom end of the stirring rod 6 by a fixing sleeve 12. The outer side of the stirring assembly is coated with a Teflon coating.
[0023] Reference Figure 2 and Figure 3The transmission mechanism 4 includes a motor 4.1, a transmission gear 4.2, and a driven gear 4.3. The motor 4.1 is fixedly mounted on one side of the upper end of the device body 1. The transmission gear 4.2 is fixedly mounted on the lower end of the motor 4.1 via a transmission shaft. The transmission gear 4.2 is meshed with the driven gear 4.3 for transmission. The driven gear 4.3 has a gear shaft 4.4 in the middle. The gear shaft 4.4 has a vertically opened threaded hole 4.5 in the middle. A lead screw 5 is installed inside the threaded hole 4.5. A bearing 4.6 is fixedly mounted on the outer side of the lower end of the gear shaft 4.4. The driven gear 4.3 is rotatably connected to the upper end of the device body 1 via the bearing 4.6.
[0024] Reference Figure 1 The lower end of the lead screw 5 is fixedly connected to the stirring rod 6. A first sealing block 7 is fixedly provided on the upper end of the inner wall of the device body 1. A second sealing block 8 is fixedly provided on the upper end of the inner wall of the ton 9. The first sealing block 7 and the second sealing block 8 are provided with internal threads. The first sealing block 7 and the second sealing block 8 are sleeved on the outside of the lead screw 5. The outer sides of the lead screw 5, the first sealing block 7, and the second sealing block 8 are all coated with Teflon coating.
[0025] Reference Figure 4 and Figure 5 The outer side of the fixed sleeve 12 is evenly distributed with four sets of connecting ears 12.1. The stirring blade 13 is movably connected to the connecting ears 12.1 through the pin 12.2. When the stirring rod 6 is not rotating, the stirring blade 13 is in a drooping and retracted state, making it easier for the stirring blade 13 to be inserted into the ton 9. When the stirring rod 6 rotates at high speed, the stirring blade 13 is dispersed under the action of centrifugal force, which can stir the liquid.
[0026] The stirring blade 13 has a notch at the end closest to the fixed sleeve 12. During the stirring process, the liquid near the stirring rod 6 is stirred to form a high vortex. The liquid collision at this point is intense and easily forms foam. The notch can reduce the collision of the liquid near the stirring rod 6 and reduce the formation of foam. The stirring blade 13 has two liquid passage holes 13.1. When the stirring blade 13 is stirring, some liquid passes through the liquid passage holes 13.1. The liquid passage holes 13.1 can promote the re-mixing of some liquid inside, enhance the stirring effect and stirring speed.
[0027] The fan 10 is made of polytetrafluoroethylene.
[0028] The gas purification package 11 is a material package containing calcium oxide or calcium hydroxide.
[0029] The usage process can be specifically described as follows:
[0030] The ton container 9 is moved into the device body 1. The conveying pipeline connecting the first raw material tank 14 and the second raw material tank 15 is connected to the ton container 9. The transmission mechanism 4 is controlled by the operation controller 2 to drive the stirring assembly into the ton container 9 at a low speed. The first sealing block 7 and the second sealing block 8 on the outside of the lead screw 5 seal the upper inner walls of the device body 1 and the ton container 9 respectively, achieving a double seal for the liquid in the ton container 9 and the gas in the annulus between the device body 1 and the ton container 9. The raw materials in the first raw material tank 14 and the second raw material tank 15 are injected into the ton container 9 using the delivery pump 3. The fans 10 on both sides of the upper inner end of the device body 1 are started by the operation controller 2 to treat the polluted gas in the annulus between the device body 1 and the ton container 9, so that it is purified by passing it through the gas purification bag 11 containing calcium oxide or calcium hydroxide. Excess gas is removed. The liquid can enter the external gas recovery device through the air outlet 16 for further processing. The motor 4.1 is started by the operation controller 2, which drives the transmission gear 4.2 to rotate, thereby driving the driven gear 4.3 to rotate. The driven gear 4.3 rotates, which drives the lead screw 5 to rotate. The lead screw 5 drives the stirring rod 6 to rotate, thereby driving the stirring blade 13 to stir. Since the first sealing block 7 and the second sealing block 8 are fixed, the first sealing block 7 and the second sealing block 8 cannot rotate when the lead screw 5 rotates. The lead screw 5 will move up and down along the internal threads of the first sealing block 7 and the second sealing block 8. The stirring blade 13 connected to it moves up and down in the liquid. The stirring blade 13 pushes the upper liquid downward and lifts the lower liquid up at the same time, thereby achieving uniform mixing of the liquid in the ton 9.
[0031] Example 2: An environmentally friendly ton-bucket mixing device for mixing acidic additives mentioned in this utility model includes a device body 1, a controller 2, a delivery pump 3, a transmission mechanism 4, a ton-bucket 9, a fan 10, a gas purification bag 11, a first raw material tank 14, and a second raw material tank 15. The transmission mechanism 4 is installed at the upper end of the device body 1, and a stirring component is provided at the lower end of the transmission mechanism 4. The ton-bucket 9 is placed inside the device body 1, and the stirring component extends into the ton-bucket 9. The fan 10 and the gas purification bag 11 are provided on both sides of the upper end of the device body 1. An air outlet 16 is provided on one side of the lower end of the device body 1, and the air outlet 16 is connected to an external gas recovery device. The first raw material tank 14 and the second raw material tank 15 are connected to the outside of the device body 1 through the delivery pump 3. The device body 1 is electrically connected to the controller 2.
[0032] The stirring assembly includes a stirring rod 6 and a stirring blade 13, with the stirring blade 13 fixedly mounted at the bottom end of the stirring rod 6 via a fixing sleeve 12.
[0033] The difference from Example 1 is:
[0034] The stirring blade 13 is a telescopic blade, which can adapt to ton containers 9 of different diameters to achieve a thorough stirring effect.

Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent transformations made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
