Description

Technical Field

[0001] This utility model relates to the field of vanadium-bearing shale processing technology, and in particular to an acid-cooking and maturing device for vanadium-bearing shale with a temperature control probe structure. Background Technology

[0002] Vanadium is a crucial strategic resource, widely used in steel production, aerospace, medical and health, electronics, and military industries. The acid-curing leaching process is a relatively new wet vanadium extraction method. The difference between acid-curing leaching and conventional leaching is the use of concentrated sulfuric acid instead of dilute sulfuric acid as the leaching agent. A small amount of concentrated acid is uniformly mixed with the ore, and a small amount of liquid is applied to the ore surface to wet it. This causes the concentrated sulfuric acid to form a thin film on the ore surface. This film coats the ore particles and penetrates into the ore through the surface pores, reacting chemically with the ore. The acid-curing leaching process not only improves vanadium recovery but also significantly reduces the amount of acid used.

[0003] Existing acid-mixing leaching equipment for vanadium-bearing shale requires a temperature detector to monitor the temperature inside the leaching tank during operation, ensuring it remains within a reasonable range to accelerate the acid-mixing leaching process. However, since the monitoring probe of the temperature detector is located inside the leaching tank, it is susceptible to corrosion from acid gases, reducing its service life. Therefore, we propose an acid-mixing leaching equipment for vanadium-bearing shale with a temperature-regulating probe structure to address the aforementioned problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides an embodiment of an acid-cooking and maturation device for vanadium-containing shale with a temperature-controlled probe structure, comprising a leaching tank 1, a temperature detector 3 fixedly mounted on the side of the leaching tank 1, a connecting plate fixedly mounted on the inner side of the leaching tank 1, a mounting base 5 fixedly mounted on the lower surface of the connecting plate, a monitoring probe 4 fixedly mounted on the bottom of the mounting base 5, the monitoring probe 4 and the temperature detector 3 being electrically connected by a wire, a protective component being provided between the monitoring probe 4 and the mounting base 5, the protective component comprising a first protective sleeve 6 and a second protective sleeve 7, the second protective sleeve 7 being fitted around the outer ring of the mounting base 5, the first protective sleeve 6 being fitted around the outer ring of the monitoring probe 4, a fixing sleeve 8 being fixedly mounted at the end of the second protective sleeve 7, the fixing sleeve 8 being fitted around the outer ring of the mounting base 5, and the horizontal cross-sections of the mounting base 5, the second protective sleeve 7, and the fixing sleeve 8 are all rectangular.

[0028] During use, this invention monitors the internal temperature of the leaching tank 1 using a monitoring probe 4. Since the monitoring probe 4 is susceptible to corrosion from the acidic gases inside the leaching tank 1, a protective sleeve 6 is fitted over the monitoring probe 4, and a protective sleeve 7 is fitted over the mounting base 5. The protective sleeve 6 protects the monitoring probe 4, and the protective sleeve 7 protects the mounting base 5, thus providing comprehensive protection for the monitoring probe 4, preventing corrosion from acidic gases and extending its service life. Both the protective sleeve 6 and the protective sleeve 7 are made of acid-resistant material. This invention solves the problem in existing acid-mixing and ripening equipment for vanadium-containing shale with temperature-controlled probe structures, where the monitoring probe 4 of the temperature detector 3 is located inside the leaching tank 1 and is easily corroded by acidic gases, reducing its service life.

[0029] In addition, since the monitoring probe 4 is in close contact with the mixture inside the leaching tank 1, the true temperature of the mixture can be detected. To prevent the protective sleeve 6 from falling off, a fixing component is provided between the fixing sleeve 8 and the mounting base 5. The fixing component includes a movable groove 9, which is fixedly opened inside the mounting base 5. An electric push rod 10 is fixedly installed on the top of the inner side of the mounting base 5. A lifting block is fixedly connected to the telescopic end of the electric push rod 10. A limit groove is fixedly opened at the lower end of the side of the movable groove 9. Four limit grooves are evenly distributed in a ring. A fixing groove corresponding to the limit groove is fixedly opened on the inner wall of the fixing sleeve 8. An insert rod 11 is slidably connected between the fixing groove and the limit groove. A connecting rod 12 is rotatably arranged between the insert rod 11 and the lifting block.

[0030] After the fixing sleeve 8 is placed on the outside of the mounting base 5 and the fixing sleeve 8 and the connecting plate are in contact, the electric push rod 10 is activated to drive the lifting block to move. Under the push of the connecting rod 12, the insertion rod 11 slides inside the limiting groove and inserts into the inside of the fixing groove, thereby fixing the fixing sleeve 8 on the mounting base 5 and preventing the protective sleeve 6 from falling off. When the protective sleeve 6 and the protective sleeve 7 are damaged, the operation is reversed to remove the fixing sleeve 8 from the mounting base 5, which facilitates the replacement of the protective sleeve 6 and the protective sleeve 7 and improves the convenience of device maintenance.

[0031] Furthermore, a tank cover 2 is provided on the top of the leaching tank 1 via a connecting flange. Two feed inlets 20 are fixedly provided on the top of the tank cover 2, symmetrically distributed about the center line of the tank cover 2. A stirring assembly and a recycling assembly are provided on the tank cover 2. The stirring assembly includes a second motor 21, which is fixedly located in the middle of the top of the tank cover 2. A stirring rod is rotatably provided in the middle of the bottom of the tank cover 2. The drive end of the second motor 21 is fixedly connected to the stirring rod. The material is fed into the interior of the leaching tank 1 through the feed inlets 20. The second motor 21 is started, which drives the stirring rod to rotate, thereby accelerating the uniform mixing of the material.

[0032] Furthermore, the recycling assembly includes a connecting rod 16, which is movably connected to the can lid 2 via a sliding assembly. The upper end of the connecting rod 16 is connected to a hose 19 and a branch pipe 17. Two branch pipes 17 are provided, which are symmetrically distributed about the center line of the can lid 2. A gas collection hood 18 is fixedly installed at the end of the branch pipe 17 away from the connecting rod 16. The sliding assembly includes a horizontal plate 13, which is fixedly installed on the top of the can lid 2. A sliding groove is opened inside the horizontal plate 13, and a screw 14 is rotatably installed inside the sliding groove. A slider is threadedly connected to the outer ring of the screw 14. The slider and the connecting rod 16 are fixedly connected. A motor 15 is fixedly installed at the end of the horizontal plate 13, and the drive end of the motor 15 is fixedly connected to the screw 14.

[0033] Specifically, after the material is fed into the leaching tank 1, the motor 15 is started, which drives the screw 14 to rotate, thereby moving the slider, connecting rod 16, branch pipe 17 and gas collection hood 18 forward, so that the gas collection hood 18 is directly above the feed inlet 20. The external air pump is started, and the acid gas through the feed inlet 20 passes through the gas collection hood 18, branch pipe 17, connecting rod 16 and hose 19 in sequence, and then enters the external recovery tower for acid gas recovery, avoiding waste of resources.

[0034] Furthermore, a discharge port is fixedly provided in the middle of the bottom of the leaching tank 1, and three support rods 22 arranged in a ring are fixedly provided on the edge of the bottom of the leaching tank 1.

[0035] Working principle: During use, the fixing sleeve 8 is sequentially fitted onto the monitoring probe 4 and the mounting base 5, so that the first protective sleeve 6 covers the monitoring probe 4 and the second protective sleeve 7 covers the mounting base 5, thus providing comprehensive protection for the monitoring probe 4, preventing it from being corroded by acid gas and extending its service life. After the fixing sleeve 8 and the connecting plate are in contact with each other, the electric push rod 10 is activated, which drives the lifting block to move. Under the push of the connecting rod 12, the insertion rod 11 slides inside the limiting groove and inserts into the fixing groove, thereby fixing the fixing sleeve 8 to the mounting base 5. To prevent the protective sleeve 6 from falling off the monitoring probe 4 and to facilitate its replacement, after the material is fed into the leaching tank 1, the motor 15 is started, driving the screw 14 to rotate, which in turn drives the slider, connecting rod 16, branch pipe 17 and gas collection hood 18 to move forward, so that the gas collection hood 18 is directly above the feed inlet 20. The external air pump is started, and the acid gas through the feed inlet 20 passes through the gas collection hood 18, branch pipe 17, connecting rod 16 and hose 19 in sequence before entering the external recovery tower for acid gas recovery, thus avoiding resource waste.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
