Abstract
Description
Technical Field
[0001] The utility model relates to an efficient silicon carbide sulfuric acid dilution cooler, in particular to an efficient silicon carbide sulfuric acid dilution cooler applied to the field of sulfuric acid processing. Background Art
[0002] Sulfuric acid is an inorganic strong acid, which is the most important oxygen-containing acid of sulfur. Sulfuric acid is corrosive and can react with most metals. During the production and processing of sulfuric acid, after diluting sulfuric acid, a cooler is used to reduce the temperature of sulfuric acid.
[0003] After injecting sulfuric acid into the cooler, since sulfuric acid is in a static state in the cooler, when cooling, the cooling speed of sulfuric acid near the inner wall of the cooler is different from that of sulfuric acid far from the inner wall of the cooler. Therefore, it is not only difficult to cool sulfuric acid at different positions evenly, but also takes a long time to cool. Summary of the Utility Model
[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that the existing sulfuric acid dilution cooler not only makes it difficult to cool sulfuric acid at different positions evenly, but also takes a long time to cool.
[0005] To solve the above problems, the utility model provides an efficient silicon carbide sulfuric acid dilution cooler, which includes a cooling table. A processing box is arranged on the upper side of the cooling table. A pair of adjusting motors I are fixedly connected to the upper end of the cooling table. A moving block is fixedly connected to the output end of the adjusting motor I. Electric push rods are fixedly connected to both side ends of the moving block. The telescopic end of the electric push rod is fixedly connected to a cooling box. A pair of L-shaped plates are fixedly connected between the outer end of the processing box and the cooling table. A cold air pipe, an exhaust pipe and a plurality of adjusting motors II are fixedly connected to the upper end of the processing box. The output end of the adjusting motor II movably penetrates through the upper end of the processing box from top to bottom and is fixedly connected to a moving pipe. The moving pipe is located inside the processing box and a plurality of cross pipes are fixedly connected to its outer end.
[0006] In the above-mentioned efficient silicon carbide sulfuric acid dilution cooler, it is convenient to cool sulfuric acid at different positions in the processing box evenly, and thus the overall cooling time required for sulfuric acid can be shortened.
[0007] As a further improvement of the present application, a water pipe is fixedly connected to the side end of the cooling box, and a sealing cover is threadedly connected to the outer end of the water pipe.
[0008] As a further improvement of the present application, a plugging groove is opened at the upper end of the cooling box. The maximum outer diameter of the adjusting motor II, the cold air pipe and the exhaust pipe is smaller than the width of the notch of the plugging groove. In the initial state, the center line of the cooling box and the center line of the processing box are on the same straight line, and the inner diameter of the cooling box is the same as the outer diameter of the processing box.
[0009] As a further improvement of the present application, the lower end of the processing box does not contact the upper end of the cooling table, and the lower end of the cooling box contacts the upper end of the cooling table.
[0010] As a further improvement of the present application, a base is fixedly connected to the lower end of the cooling table, and a plurality of universal wheels are fixedly connected to the lower end of the base.
[0011] As another improvement of the present application, a reinforcing plate is fixedly connected to the upper end of the base, and a refrigerating box is fixedly connected to the upper end of the reinforcing plate.
[0012] In summary, the cooler facilitates the uniform cooling of sulfuric acid at different positions in the processing box, thereby shortening the overall cooling time required for sulfuric acid. At the same time, it can also handle the heated cooling box so that the cooling box can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following describes in detail the two embodiments of the present application with reference to the drawings.
[0021] The first embodiment:
[0022] Figures 1-4An efficient silicon carbide sulfuric acid dilution cooler is shown, including a cooling table 1. A processing box 2 is provided on the upper side of the cooling table 1. A cooling liquid is contained in the cooling box 3. A pair of adjusting motors 1 are fixedly connected to the upper end of the cooling table 1. A moving block 5 is fixedly connected to the output end of the adjusting motor 1. Electric push rods 6 are fixedly connected to both side ends of the moving block 5. Those skilled in the art can make an optimal selection of the model of the electric push rod 6, such as ETS-50. The telescopic end of the electric push rod 6 is fixedly connected to the cooling box 3. A pair of L-shaped plates 7 are fixedly connected between the outer end of the processing box 2 and the cooling table 1. A cold air pipe 9, an exhaust pipe 10 and a plurality of adjusting motors 2 are fixedly connected to the upper end of the processing box 2. Those skilled in the art can make an optimal selection of the model of the adjusting motor 2, such as model Y80M1-2. The output end of the adjusting motor 2 movably penetrates through the upper end of the processing box 2 from top to bottom and is fixedly connected to a moving pipe 11. The moving pipe 11 is located inside the processing box 2 and a plurality of cross pipes 12 are fixedly connected to its outer end;
[0023] A water pipe 13 is fixedly connected to the side end of the cooling box 3. During use, the cooling liquid is injected into the cooling box 3 through the water pipe 13. A sealing cover is threadedly connected to the outer end of the water pipe 13. A plugging groove 14 is opened at the upper end of the cooling box 3. The maximum outer diameters of the adjusting motor 2, the cold air pipe 9 and the exhaust pipe 10 are all smaller than the width of the notch of the plugging groove 14. Through the plugging groove 14, it is convenient for the cooling box 3 to pass through the adjusting motor 2, the cold air pipe 9 and the exhaust pipe 10 and be sleeved on the processing box 2. In the initial state, the center line of the cooling box 3 and the center line of the processing box 2 are on the same straight line, and the inner diameter of the cooling box 3 is the same as the outer diameter of the processing box 2. The lower end of the processing box 2 does not contact the upper end of the cooling table 1, and the lower end of the cooling box 3 contacts the upper end of the cooling table 1. A base 15 is fixedly connected to the lower end of the cooling table 1. A plurality of universal wheels 16 are fixedly connected to the lower end of the base 15.
[0024] During use, the diluted sulfuric acid is injected into the processing box 2 through the exhaust pipe 10. A pair of electric push rods 6 near the left and right side ends of the processing box 2 are started, which push the cooling box 3 to sleeve the pair of cooling boxes 3 on the processing box 2. Therefore, the inner wall of the cooling box 3 will fit with the outer end of the processing box 2. The temperature of the cooling box 3 is lower than that of the processing box 2, and the cooling box 3 is used to absorb the heat transferred from the processing box 2, so that the sulfuric acid in the processing box 2 is cooled. At the same time, the adjusting motor two 8 is started to make the moving pipe 11 rotate in the processing box 2. When the moving pipe 11 moves, the cross pipe 12 will move with it, so that the cross pipe 12 rotates in the processing box 2 and stirs the sulfuric acid to change its state from static to moving. Therefore, it is convenient for the sulfuric acid at different positions in the processing box 2 to be cooled evenly, which can shorten the sulfuric acid cooling time. At the same time, the cold air pipe 9 can create conditions for the cooling gas to enter the processing box 2. Therefore, a device for conveying the cooling gas (not shown in the figure) can be externally connected to the cold air pipe 9, and the cooling device is used to convey the cooling gas into the processing box 2 through the cold air pipe 9 to further improve the sulfuric acid cooling speed;
[0025] When the cooling box 3 sleeved on the processing box 2 is used for a certain period of time, the temperature of the coolant in the cooling box 3 will rise, so its refrigeration effect will decrease. At this time, the electric push rods 6 on both sides of the moving block 5 need to be started at the same time, and their telescopic ends will move toward the side close to the moving block 5. Therefore, the cooling box 3 sleeved on the processing box 2 will move toward the moving block 5 and separate from the processing box 2, and another spare cooling box 3 will also approach the moving block 5. Then, the adjusting motor one 4 is started, and its output end drives the moving block 5 to rotate 180 degrees in the horizontal direction, so as to swap the positions of the used cooling box 3 and the spare cooling box 3. After the swapping, the electric push rod 6 is started again to sleeve the spare cooling box 3 on the processing box 2 and use it to continue to cool the sulfuric acid in the processing box 2. The operation steps for replacing the cooling box 3 of this cooler are simple and take less time.
[0026] The second implementation mode:
[0027] On the basis of the first implementation mode, this implementation mode newly adds a fixed plate 17 and a refrigeration box 18, and the rest is the same as the first implementation mode.
[0028] Figure 5 It is shown that a reinforcing plate 17 is fixedly connected to the upper end of the base 15 to support the refrigeration box 18 and improve the stability of the refrigeration box 18. The refrigeration box 18 is fixedly connected to the upper end of the reinforcing plate 17. The refrigeration principle of the refrigeration box 18 is vapor compression refrigeration, which is similar to the refrigeration principle of a refrigerator.
[0029] In the initial state, the spare cooling box 3 is inserted inside the refrigerated box 18, and the refrigerated box 18 is used to cool and keep warm the spare cooling box 3. After moving the spare cooling box 3 out of the refrigerated box 18 and swapping its position with the used cooling box 3, the electric push rod 6 needs to be activated to push the used cooling box 3 into the refrigerated box 18. The refrigerated box 18 is used to refrigerate the used cooling box 3, thereby cooling the coolant in the cooling box 3 for standby. Therefore, this cooler can handle the heated cooling mechanism, enabling the cooling mechanism to be recycled. At the same time, it can also ensure the continuity of the cooling process for sulfuric acid.
[0030] Combined with the current actual requirements, the above-described implementation method adopted in this application has a protection scope that is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
