Description

Technical Field

[0001] The utility model relates to the technical field of heating reaction equipment, in particular to a heating reaction mechanism. Background Art

[0002] The heating reaction mechanism (also known as a heating reaction device, heating reaction furnace, etc.) plays a vital role in chemical reactions. The core function of the heating reaction mechanism is to provide the required temperature conditions for the chemical reaction through a heating source.

[0003] A search revealed patent publication number CN219714095U, for example, which discloses a sewage anaerobic reaction heating mechanism comprising a sewage tank. The mechanism is characterized in that the sewage tank is provided with a partition plate, which forms a sewage storage tank and a heating tank, and the partition plate is provided with a connecting port connecting the sewage storage tank and the heating tank. The heating tank is also provided with a heating mechanism for heating the sewage in the heating tank and a stirring mechanism for improving the temperature uniformity within the sewage tank. The heating mechanism is a coil installed at the bottom of the heating tank. This utility model utilizes a coil, through which steam is introduced, and heat is exchanged between the steam and the sewage in the heating tank, thereby heating the sewage in the heating tank. The coil increases the heat exchange time between the steam and the sewage, improving the heating effect and efficiency. The stirring mechanism is provided to agitate the sewage in the heating tank, thereby improving the uniformity of the sewage heating temperature and preventing the discharged sewage from being too hot or too cold, which could affect subsequent treatment.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, a coil is set in the heating pool. When the reaction medium needs to be heated, heating steam is transported into the coil to achieve the effect of heating the reaction medium in the heating pool. However, in reality, the coil in the above-mentioned comparative document is coiled in the heating pool. When the steam enters through the inlet of the coil, the steam gradually exchanges heat with the reaction medium. As the steam moves to the outlet position in the coil, the temperature of the steam will become lower and lower. When the temperature of the reaction medium is slightly higher than the steam after cooling, reverse heat exchange will occur, thereby reducing the efficiency of heating the reaction medium. Moreover, the coil is placed in the heating pool by coiling. When used for a long time, scale will appear in the coil and it is difficult to clean and maintain it, resulting in a decrease in subsequent heating efficiency. Therefore, there is an urgent need to improve the heating reaction mechanism in this field to solve the defects of the existing technology. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0028] See also Figures 1-6 A heating reaction mechanism includes a cell body 1, one side of the cell body 1 is provided with a discharge port 2 which is connected to the interior thereof and can be opened and closed, and opposite sides of the cell body 1 are respectively provided with a plurality of first heat exchange medium delivery pipes 3 and second heat exchange medium delivery pipes 4, which are connected to each other, and a diversion box 5 which is connected to the ends of the plurality of first heat exchange medium delivery pipes 3 and second heat exchange medium delivery pipes 4 away from the cell body 1 is fixedly installed, and a heat exchange medium inlet pipe 6 and a heat exchange medium discharge pipe 7 which are connected to the interior thereof are respectively provided on one side of the two diversion boxes 5, and a stirring unit for stirring is provided in the cell body 1.

[0029] Specifically, when the reaction medium needs to be heated, it is discharged into the cell body 1, and the heated heat exchange medium is passed from the heat exchange medium inlet pipe 6 into the diversion box 5 through the external heating device. The heat exchange medium is diverted to several first heat exchange medium delivery pipes 3 through the diversion of the diversion box 5. The first heat exchange medium delivery pipe 3 delivers the heat exchange medium to the second heat exchange medium delivery pipe 4. At this time, the reaction medium passes through the cell body 1 to exchange heat, and then the heat exchange medium is discharged through the heat exchange medium discharge pipe 7. At the same time, the stirring unit in the cell body 1 is started to heat the cell body. 1 is stirred, and the flow path of the heat exchange medium in the pool body 1 is short, thereby preventing reverse heat exchange between the heat exchange medium and the medium to be reacted, and improving the heating efficiency of the medium to be reacted. At the same time, by providing a plurality of first heat exchange medium delivery pipes 3 and second heat exchange medium delivery pipes 4 that are interconnected, it is convenient to perform descaling and maintenance on the first heat exchange medium delivery pipe 3 or the second heat exchange medium delivery pipe 4 in the later stage. The medium to be reacted after heating is discharged through the discharge port 2. It is worth noting that the above-mentioned heat exchange medium can be gas or liquid.

[0030] As a technical optimization solution of the present invention, several first heat exchange medium delivery pipes 3 and second heat exchange medium delivery pipes 4 are arranged in an inclined straight line, and there are two groups of stirring units distributed on both sides of the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4. The stirring unit includes two first rotating shafts 8 and second rotating shafts 9 rotatably connected between opposite side walls in the pool body 1. Several stirring blades 10 are fixedly connected to the sides of the first rotating shaft 8 and the second rotating shaft 9. A driving unit 11 for simultaneously driving the second rotating shaft 9 to rotate is provided on the side of the pool body 1.

[0031] Specifically, the first rotating shaft 8 and the second rotating shaft 9 are driven to rotate simultaneously by the driving unit 11 to accelerate the fluidity of the medium to be reacted, and the first heat exchange medium conveying pipe 3 and the second heat exchange medium conveying pipe 4 occupy a smaller space, so that the stirring blade 10 can fully stir the medium to be reacted in the pool body 1, thereby improving the efficiency of the overall device in heating the medium to be reacted.

[0032] As a technical optimization solution of the present invention, the drive unit 11 includes a drive motor 12 fixedly mounted on the side of the pool body 1, one end of the first rotating shaft 8 extends to the outside and is fixedly mounted on the output end of the drive motor 12, and a first transmission wheel 13 is fixedly mounted on the side of the end of the first rotating shaft 8 located on the outside, and the side of the pool body 1 is rotatably connected with a first rotating shaft 14 and a second rotating shaft 17, and a second transmission wheel 15 adapted to the first transmission wheel 13 is fixedly mounted on the side of the first rotating shaft 14, and a first transmission belt 16 for transmission is sleeved between the first transmission wheel 13 and the side of the first rotating shaft 14, one end of the second rotating shaft 9 extends to the outside and a first gear 20 is fixedly mounted on the side of its end, and a third transmission wheel 18 adapted to the second transmission wheel 15 and a second gear 21 meshing with the first gear 20 are fixedly mounted on the side of the second rotating shaft 17, and a second transmission belt 19 for transmission is sleeved between the sides of the second transmission wheel 15 and the third transmission wheel 18.

[0033] Specifically, the drive motor 12 is started, and the output end of the drive motor 12 drives the first rotating shaft 8 to rotate. When the first rotating shaft 8 rotates, it drives the first transmission wheel 13 to rotate. The first transmission wheel 13 drives the second transmission wheel 15 to rotate through the first transmission belt 16. The second transmission wheel 15 drives the third transmission wheel 18 to rotate through the second transmission belt 19. The third transmission wheel 18 drives the second gear 21 to rotate through the second rotating shaft 17. When the second gear 21 rotates, it drives the first gear 20 to rotate. When the first gear 20 rotates, it drives the second rotating shaft 9 to rotate, thereby realizing synchronous and counter-rotating rotation of the first rotating shaft 8 and the second rotating shaft 9, realizing convective agitation of the medium to be reacted in the cell body 1, and accelerating the heating efficiency of the medium to be reacted in the cell body 1.

[0034] As a technical optimization solution of the present invention, a plurality of diverter rings 22 are provided in the diverter box 5, and the diverter rings 22 are adapted to the first heat exchange medium delivery pipe 3. When the heat exchange medium is liquid, the diverter rings 22 can prevent the flow rate between the first heat exchange medium delivery pipe 3 close to the heat exchange medium inlet pipe 6 and the first heat exchange medium delivery pipe 3 far away from the heat exchange medium inlet pipe 6 from being too different, thereby ensuring that the heat exchange medium can be transported in each first heat exchange medium delivery pipe 3.

The opposite ends of the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4 are connected by connecting flanges 23 and fastening bolts. A seal 24 is embedded between the opposite ends of the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4, and the seal 24 is elastic.

[0036] Specifically, when the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4 need to be installed, the opposite ends of the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4 are inserted into the pool body 1, and the connecting flanges 23 are respectively threadedly connected to the opposite ends of the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4. The seal 24 is embedded between the ends of the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4. The two connecting flanges 23 are connected by tightening bolts, and the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4 are sealed with the pool body 1 to facilitate alignment for installation. When the scale in the first heat exchange medium delivery pipe 3 and the second heat exchange medium delivery pipe 4 needs to be treated later, it is also convenient to disassemble them.

[0037] Among them, the above-mentioned drive motor 12 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The drive motor 12 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
