Description

Technical Field

[0001] The utility model relates to the technical field of chemical production equipment, in particular to a chemical heating reaction kettle. Background Technique

[0002] Generally understood, a reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food. They are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, polymerization kettles, etc. The materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials. Through the structural design and parameter configuration of the container, heating, evaporation, and cooling required by the process are realized.

[0003] One of the main means for the existing reaction kettles to carry out heating is to use high-temperature steam for heating or electric heating for fixed-point heating. However:

[0004] 1. Due to the high temperature of high-temperature steam, the temperature is not easy to control, and during the heating process, it is necessary to heat water to generate steam for heating, which is rather troublesome. In addition, heat is lost during the transmission of high-temperature steam, resulting in energy waste.

[0005] 2. Since electric heating is carried out by a resistance wire for fixed-point heating, the heating method is fixed-point diffusion, which easily causes uneven heating.

[0006] In addition, traditional reaction kettles with heating functions are designed with an integrated structure of the heating mechanism and the reaction kettle. Not only is the manufacturing cost high, but also when either the reaction kettle or the heating mechanism is damaged, on the one hand, it is difficult to repair and maintain, and on the other hand, once it cannot be repaired, the whole machine needs to be scrapped, resulting in inconvenience in the use and maintenance of the equipment.

A plurality of installation slots 12 are arranged on the side wall of the ring-shaped heating outer box 10, and a hot and cold air blower 13 is installed inside the installation slot 12, and the hot and cold air blower 13 blows air to the outer wall of the reactor body 24. The top of the side wall of the ring-shaped heating outer box 10 is fixed to the outer ring of the bearing 25, and the reactor body 24 passes through the inner ring of the bearing 25. An air permeable gap is arranged between adjacent balls of the bearing 25. The discharge pipe 9 passing through the installation base 1 is rotatably connected to the midpoint of the bottom of the reactor body 24, and the discharge pipe 9 is communicated with the internal cavity of the reactor body 24.

[0027] When the device is in use, first inject the liquid material to be reacted into the reactor body 24, and then start the hot and cold air blower 13, so that the hot and cold air blower 13 blows hot air to the outer wall of the reactor body 24. At the same time, rotate the reactor body 24 so that the reactor body 24 rotates to receive the wind, thereby making the heating surface more uniform. When heating, control the operating power of the hot and cold air blower 13 and the temperature of the blown hot air according to the temperature of the liquid material inside the reactor body 24. The excess hot air is discharged from between the balls of the bearing 25, so that the hot air flows as much as possible between the ring-shaped heating outer box 10 and the reactor body 24, further making the heating more uniform.

[0028] Embodiment 2

[0029] Based on the chemical heating reactor of Embodiment 1, as Figures 1-2 shown, a cover plate 15 is arranged on the top of the reactor body 24, and a sealing sleeve plate 14 sealed with the reactor body 24 is arranged at the bottom of the cover plate 15. An injection pipe 5 communicated with the internal cavity of the reactor body 24 is arranged on the cover plate 15.

[0030] At this time, the liquid material to be reacted is injected into the reactor body 24 from the injection pipe 5. The added cover plate 15 and sealing sleeve plate 14 can make the top achieve detachable sealing. When maintaining or deeply cleaning the inside of the reactor body 24, the cover plate 15 can be removed, so that maintenance or cleaning personnel / equipment can conveniently enter the inside of the reactor body 24.

[0031] Embodiment 3

[0032] Based on the chemical heating reactor of Embodiment 2, as Figures 1-2 shown, a second motor 16 is fixedly installed on the top of the cover plate 15, and the output end of the second motor 16 is fixedly connected to the top end of the first rotating shaft 20. The first rotating shaft 20 extends into the reactor body 24, and a plurality of first connecting blocks 19 are arranged on the shaft body inside the reactor body 24. A scraper 11 is connected to each of the first connecting blocks 19 through a connecting mechanism.

[0033] When it is necessary to clean the inner wall of the reactor body 24, the second motor 16 can be started to drive the first rotating shaft 20 to rotate, and then the scraper 11 can be driven to rotate through the first connecting block 19 and the connecting mechanism to scrape the inner wall of the reactor body 24.

[0034] According to an embodiment of the present invention, the connecting mechanism is a straight rod. This setting is relatively simple and has a low cost.

[0035] According to an embodiment of the present invention, as Figure 3 shown, the connecting mechanism includes a side plate 18 fixed to the first connecting block 19. A chute 21 is formed inside the side plate 18, and a second slider 22 is slidably connected inside the chute 21.

The side of the second slider 22 facing away from the telescopic spring 17 is fixedly connected to the scraper 11 through a second connecting plate 23.

[0036] This setting enables an elastic telescopic connection relationship between the scraper 11 and the first connecting block 19 along the radial direction of the reactor body 24, so that the scraper 11 is elastically pressed against the inner wall of the reactor body 24 by the telescopic spring 17 for scraping. With this elastic connection relationship, the scraper 11 can be elastically adapted to the shape or structure of the inner wall of the reactor body 24, avoiding the situation that when rigidly connected, the scraper 11 cannot scrape the concave part or cause impact damage to the convex part.

Exemplarily, the detachable and fixed connection can adopt the following connection method: several installation grooves matching the struts 8 are provided on one side plate surface of the rotating plate 4 facing the bottom of the reaction kettle body 24. When the reaction kettle body 24 is hoisted into the internal part of the annular heating outer box 10, by adjusting the position of the reaction kettle body 24, the bottom of the strut 8 is inserted into the installation groove to complete the detachable fixation.

[0042] Through the addition of several struts 8, hot air can flow through the bottom of the reaction kettle body 24 and heat the bottom of the reaction kettle body 24, thereby further improving the heating uniformity and efficiency.

A rotating ring 3 is slidably provided within the annular groove 6, and the top of the rotating ring 3 passes through the open end of the annular groove 6 and is fixedly connected to the rotating plate 4.

[0045] This setting can play a role in supporting and rotating limit for the rotating plate 4, sharing the stress generated during the rotation process, reducing the rotational stress borne by the discharge pipe 9, or enabling the discharge pipe 9 not to bear the rotational stress.

[0046] Taking the above ideal embodiments based on the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
