Description

Technical Field

[0001] This utility model relates to the technical field of sulfuric acid preheating devices, specifically to a sulfuric acid preheating device. Background Technology

[0002] Sulfuric acid is one of the most reactive diprotic inorganic strong acids. It can react with most metals. High concentrations of sulfuric acid have strong hygroscopic properties and release a large amount of heat when mixed with water. It also has strong corrosive and oxidizing properties.

[0003] When purifying sulfuric acid, a preheating device is required to heat the sulfuric acid and improve its purity. However, after the preheating container is removed, the heat inside the device is quickly dissipated to the outside, causing the temperature inside the device to drop rapidly. When large quantities of sulfuric acid need to be heated and purified in batches, a longer heating process is required, which not only affects the efficiency of batch heating of sulfuric acid but also increases energy consumption during the heating process, making it unsuitable for use. Utility Model Content

[0004] Based on the above description, this utility model provides a sulfuric acid preheating device to solve the problem that a large amount of heat is dissipated after the sulfuric acid is heated and taken out, which affects the batch processing efficiency of sulfuric acid.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sulfuric acid preheating device includes a shell and a heating plate. A container slot is provided through the surface of the shell. An insulation layer is provided on the inner side of the shell. A sealing component is located on the inner side of the shell. The sealing component includes a rotating shaft and a sealing plate. The rotating shaft is disposed on the surface of the sealing plate and on the inner side of the shell. A protrusion is provided on the surface of the sealing plate. A spring telescopic cylinder is disposed on the inner side of the shell. The output end of the spring telescopic cylinder is in contact with one side of the protrusion.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the surface of the sealing plate is provided with a plurality of grooves, each groove containing a metal ball, and the metal balls are located inside the container slot.

[0008] Furthermore, a sealing ring is provided on the inner side of the shell near the location of the container slot, and the side of the sealing ring away from the shell is in close contact with the surface of the sealing plate.

[0009] Furthermore, the inner side of the housing is provided with several supports, and a connecting ring is provided between the several supports, and a rubber ring is provided on the inner side of the connecting ring.

[0010] Furthermore, the surface of the housing is provided with a protruding rod, and a cover plate is provided on the outside of the protruding rod.

[0011] Furthermore, the diameter of the cover plate is adapted to the diameter of the container slot.

[0012] Furthermore, the cover plate has a handle on its surface and a vent is provided through its surface.

[0013] Furthermore, a threaded hole is provided at the end of the protruding rod away from the housing, and a bolt is provided at one end of the protruding rod through the threaded hole.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] By installing a sealing component, a spring telescopic cylinder, and an insulation layer inside the shell, the container slots opened in the shell can automatically switch between opening and closing according to the positional relationship between the preheating container and the sealing component. This avoids the phenomenon of a large amount of heat dissipation after the preheating container containing sulfuric acid is taken out, which is more conducive to the efficient preheating of sulfuric acid in batches and also reduces the operating energy consumption of the heating plate.

[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] This embodiment provides a sulfuric acid preheating device, which is more conducive to the efficient batch heating of sulfuric acid during use. Specifically, as shown in the example... Figures 1-3 As shown, the device includes a shell 1, a heating plate 2 for preheating an external container, a sealing element 3, and a spring telescopic cylinder 4. A container slot 11 (not shown) is provided through the surface of the shell 1 for placing a preheating container (such as a beaker). The shape and size of the container slot 11 are identical to those of the preheating container. An insulation layer 14, made of glass wool, is provided inside the shell 1. The sealing element 3 is located inside the shell 1 and includes a rotating shaft 31 and a sealing plate 32. The rotating shaft 31 is positioned on the surface of the sealing plate 32. 1. A sealing plate 32 is located inside the housing 1 and close to the container slot 11. The surface of the sealing plate 32 is provided with a protrusion 321. A spring telescopic cylinder 4 is located inside the housing 1. The output end of the spring telescopic cylinder 4 is in contact with one side of the protrusion 321. The spring telescopic cylinder 4 is in a compressed state, so that the container slot 11 opened in the housing 1 can automatically switch between opening and closing according to the positional relationship between the preheated container and the sealing member 3. This avoids the heat energy inside the housing 1 from being dissipated to the outside through the container slot 11 after preheating, thus ensuring the long-term preservation of the high temperature inside the housing 1.

[0025] like Figure 4 As shown, in this embodiment, the top surface of the sealing plate 32 is provided with multiple grooves 322 at equal intervals, and each groove 322 is provided with a metal ball 5. The multiple metal balls 5 are located inside the container slot 11, so that when the operator inserts the preheating container into the shell 1 through the container slot 11, the surface of the preheating container can directly contact the surface of the multiple metal balls 5, and the metal balls 5 rotate when they are inserted, thus avoiding the situation where the preheating container directly contacts the surface of the sealing plate 32 during the insertion process, which may cause wear.

[0026] like Figures 1-2As shown, in this embodiment, a sealing ring 20 is provided on the inner side of the shell 1 and near the position of the container slot 11. The side of the sealing ring 20 away from the shell 1 is in close contact with the surface of the sealing plate 32, which makes the sealing effect of the container slot 11 in the closed state better and more conducive to the preservation of heat energy inside the shell 1.

[0027] like Figures 1-3 As shown, in this embodiment, the inner side of the shell 1 is provided with two supports 12, and a connecting ring 6 is provided between the two supports 12. The inner side of the connecting ring 6 is provided with a rubber ring 7. The inner diameter of the rubber ring 7 is equal to the diameter of the container slot 11. This allows the rubber ring 7 to effectively cushion the preheating container from sliding when the preheating container is inserted into the shell 1, thus preventing the preheating container from sliding down rapidly due to the rotation of the metal ball 5 and causing direct collision with the heating plate 2.

[0028] like Figure 1 As shown, in this embodiment, the surface of the shell 1 is provided with a protruding rod 13, and the outer side of the protruding rod 13 is provided with a cover plate 8. The diameter of the cover plate 8 is adapted to the diameter of the container slot 11. The surface of the cover plate 8 is provided with a handle 81, and the surface of the cover plate 8 is provided with a vent 82. The end of the protruding rod 13 away from the shell 1 is provided with a threaded hole 131, and one end of the protruding rod 13 is provided with a bolt 9 through the threaded hole 131, so that the operator can grasp the handle 81 to rotate the cover plate 8, so that the cover plate 8 slides into the container slot 11, thereby achieving the sealing effect of the container slot 11 and preventing external impurities from easily falling into the shell 1 after the preheating container is used.

[0029] During the use of the above-mentioned sulfuric acid preheating device, the operator can insert the preheating container containing sulfuric acid into the container slot 11, so that the bottom surface of the preheating container is in contact with the surface of multiple metal balls 5. The container is then inserted into the housing 1 and pressure is applied downwards, causing the sealing plate 32 to rotate via the rotating shaft 31. During the pressure and rotation, the output end of the spring telescopic cylinder 4, through the protrusion 321, achieves a squeezing effect on the preheating device with the sealing plate 32, until the bottom surface of the preheating device contacts the top surface of the heating plate 2, thus achieving the preheating effect. After preheating, the operator can grasp the preheated device and apply upward pressure, moving it away from the container slot 11. The sealed part 3, under the support of the spring telescopic cylinder 4, rotates and resets, and the sealed part 3 and the sealing ring 20 are in close contact, preventing a large amount of heat from dissipating and affecting the batch preheating processing effect of sulfuric acid.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
