DETAILED DESCRIPTION

[0035] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] like Figure 1 As shown, this embodiment proposes an automatically controlled molten sulfur kettle, including a kettle body 1, having a cavity 19, the kettle body 1 also having a feed port 2 and a separation liquid outlet 3 connected to the cavity 19, the separation liquid outlet 3 is located next to the feed port 2, and a feed hopper 6 is arranged on the outside of the kettle body 1, the feed hopper 6 is connected to the feed port 2, including: a circulation pipeline 402, which is arranged on the kettle body 1, one end of which is connected to the cavity 19, and the other end of which is connected to the feed port 2, and the pipe body of the circulation pipeline 402 is located on the outside of the top surface of the kettle body 1; a feed pump 401, which is arranged on the circulation pipeline 40 and has a feed end; a feed pipeline 403, one end of which is connected to the feed hopper 6, and the other end of which is connected to the feed end.

[0037] In the above scheme, it should be noted that an internal circulation outlet is provided on the kettle body 1, one end of the circulation pipeline 402 is connected to the internal circulation outlet, and the circulation pipeline 402 forms an internal circulation loop through the liquid inlet pump, the feed port 2 and the cavity 19, so as to quickly heat the internal circulation of the kettle body 1 and perform secondary treatment on the separated liquid to ensure the clarity of the separated liquid. Moreover, since the feed pipeline 403 is connected to the circulation pipeline 402, it is also possible to preheat the material in advance, so as to facilitate the material to enter the kettle body 1 and improve production efficiency.

[0038] Furthermore, a preheater 5 is disposed inside the cavity 19 to preheat the material flowing from the feed port 2 to the cavity 19 .

[0039] In the above scheme, the internal circulation loop cooperates with the preheater 5 to perform rapid internal circulation heating at the feed port 2 of the kettle body 1 and the separation liquid outlet 3, which can not only preheat the material and improve the melting effect of the material, but also perform secondary heating treatment on the separation liquid to ensure the clarity of the separation liquid, which is beneficial to environmental protection and improves production efficiency.

[0040] Furthermore, it also includes: an internal heating unit 8, which is arranged in the kettle body 1, and the internal heating unit 8 has a first steam inlet 801 and a first steam outlet 802, and the first steam inlet 801 and the first steam outlet 802 are both opened on the side wall of the kettle body 1; an external heating unit 7, which is arranged on the circumference of the outer wall of the kettle body 1, and the external heating unit 7 has a second steam inlet 701 and a second steam outlet 702.

[0041] In the above scheme, both the internal heating unit 8 and the external heating unit 7 are steam heated, and the heat of the steam is used to heat the inside and outside of the kettle body 1 synchronously, thereby improving the heating effect. It should be noted that the internal heating unit 8 is located in the middle section and the bottom section of the kettle body 1, and the preheater 5 is arranged in the middle section and the top section of the kettle body 1. Through the cooperation of the internal heating unit 8 and the preheater 5, the inside of the kettle body 1 can be heated in a large range, thereby improving the heating effect. In addition, the external heating unit 7 also firmly covers the outer wall of the kettle body 1, thereby improving the heating range of the external heating unit 7 on the kettle body 1.

[0042] Furthermore, the external heating unit 7 is a coil-type heating tube. The traditional jacket structure is changed to an external coil structure, which eliminates the bottleneck of the large-scale jacket structure, ensures heating uniformity, saves manufacturing materials, and ensures heat exchange efficiency. It is beneficial for the kettle body 1 to break through the traditional height limit. The coil steam heating design replaces the previous jacket steam heating design, breaking through the capacity design bottleneck, realizing the design and manufacture of super-large kettles, reducing weight, enhancing thermal conductivity uniformity, and having higher heating efficiency. The use of steam coil technology can improve the thermal efficiency and heat exchange efficiency of the equipment, reduce energy consumption and production costs.

[0043] Furthermore, the kettle body 1 has a slag discharge port.

[0044] Furthermore, an automatic sensor connector 11 is provided on the kettle body 1, and also includes: a sensor assembly, which is provided on the kettle body 1, and the sensor assembly is electrically connected to the automatic sensor connector 11; a controller, which is communicatively connected to the sensor assembly, and the controller is used to receive detection information of the sensor assembly; the controller is also electrically connected to the internal heating unit 8 and the external heating unit 7.

[0045] In the above scheme, the sulfur melting process is controlled by a comprehensive computer automation system: the computer control system is used to comprehensively control the feeding, heating, melting, sulfur discharge, slag discharge, and liquid discharge of the foam sulfur. Through the automatic adjustment of relevant parameters, the control equipment is guaranteed to operate in the best state, that is, the discharged separation liquid is clearer, the converted crystalline sulfur is more, the energy consumption is lower, and the efficiency is higher. It can also automatically discharge sulfur and slag, reducing labor intensity and human contact with the harsh environment. The new sulfur melting kettle adopts environmentally friendly materials and structural design to reduce the generation and emission of pollutants and meet environmental protection requirements.

[0046] Furthermore, the sensor assembly includes: a temperature sensor 10, which is provided in a plurality of numbers and is arranged in the kettle body 1 at equal intervals along the axial direction of the kettle body 1, and is used to detect the kettle temperature at different height positions in the kettle body 1; a pressure sensor 16, which is connected to the automatic control sensor connector 11, and is used to detect the kettle pressure; a flow sensor 17, which is arranged in the kettle body 1, and is used to detect the material discharge speed.

[0047] In the above scheme, the controller is connected to the computer for communication, and a comprehensive computer automation control system is adopted. The liquid levels of sulfur, slag, etc. are introduced into the control system through liquid level sensors, which can accurately judge and control the liquid conditions in the observation container. According to the liquid conditions, the program can automatically adjust the pressure, temperature, flow and other related parameters. It can realize functions such as full automatic control, parameter recording, and fault diagnosis, and improve the stability and reliability of the equipment.

[0048] Furthermore, it also includes: a liquid level sensor, which is arranged in the kettle body 1 and is used to detect the liquid level in the kettle body 1. The liquid level sensor is electrically connected to the controller.

[0049] Furthermore, it also includes: a skirt 18, which is arranged below the kettle body 1. Furthermore, the bottom of the kettle body 1 has a discharge port 15, and also includes: a discharge pipe 14, one end of which is connected to the discharge port 15, and the other end passes through the side wall of the skirt 18. Adding the skirt 18 structure: makes the installation of the molten sulfur kettle simpler, more convenient and more economical. When installing a traditional molten sulfur kettle, manufacturers using the molten sulfur kettle need to build a factory building or a steel structure support to install the molten sulfur kettle. After using the skirt 18 structure, these costs are saved and the construction period is shortened, which is more suitable for the needs of manufacturers in different situations. Moreover, the coil structure enables molten sulfur kettles of various specifications to use the skirt 18 structure.

[0050] The process is as follows: the sulfur-containing solution enters the kettle body 1 from the feed port 2, passes through the preheater 5, and is placed at an appropriate position in the kettle body 1 for heating to separate and melt the sulfur. At this time, the separation liquid rises and flows out from the separation liquid outlet 3 to achieve sulfur-liquid separation; when the automatic control system detects that the molten sulfur has reached an appropriate liquid level, the slag discharge valve is opened to allow the slag to flow out from the slag discharge port to achieve automatic slag and sewage discharge, and automatic intermittent and continuous sulfur discharge can be achieved according to the liquid sulfur level; the circulating heating port can quickly increase the solution temperature in the kettle body 1 during operation, and can also perform secondary sulfur melting on part of the separation liquid to further improve the clarity of the separation liquid. In addition, due to the large-scale kettle, the number of equipment and the occupied space are reduced, and the investment cost and equipment maintenance difficulty are reduced; the installation of a skirt seat makes on-site installation simpler and easier, and greatly reduces the installation cost.

[0051] Through the above technical scheme, the problems in the related technologies such as low recovery efficiency of the molten sulfur kettle, inability to separately discharge sulfur slag, inability to accurately grasp the liquid sulfur level during sulfur discharge operation, and difficulty in timely manual adjustment of relevant parameters of the molten sulfur kettle within the required range are solved. The clarity of the separated liquid is further improved, the labor intensity of workers is reduced, and environmental protection and production efficiency are improved.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
