Description

Technical Field

[0001] The utility model belongs to the technical field of chemical material drying equipment, and in particular relates to an integrated continuous drying equipment for a sulfonating agent. Background Art

[0002] The reaction mechanism of the sulfonating agent is the reaction of sodium pyrosulfite and formaldehyde. The product of nucleophilic addition is a white precipitate of sodium hydroxymethylsulfonate CH 2 (OH)-SO 3 Na, this substance is easy to lose water, but also easy to absorb moisture. It is added to asphalt powder as a product detection indicator. Sulfonating agent is used in petroleum drilling fluid additives. After the reactants are released, they must be dried before use. They have a large water content and need to be dried before being sealed to isolate the air and prevent moisture.

[0003] In the utility model patent with the announcement number CN218096976U, a drying box for sulfonated polysulfone is disclosed. The drying box for sulfonated polysulfone is provided with a drying device, sulfonated polysulfone is poured into a placing box, and is dried by a first fan and a heating wire, while a first motor drives a stirring plate to stir, and a second motor is started to drive the placing box to move up and down, so that the placing box can vibrate, and the sulfonated polysulfone inside the placing box can be turned over by vibration, so that the sulfonated polysulfone can be evenly dried, thereby improving the drying efficiency.

[0004] However, in the drying device, the fan is located above the box. Even if the first fan and the heating wire can perform hot air drying on the sulfonated polysulfone placed in the box, based on the principle that hot air rises and cold air falls, very little hot air acts on the sulfonated polysulfone, and the heating is uneven. Not only does it take a long time to dry it, resulting in a long waiting time and low drying efficiency, but the sulfonated polysulfone is not dried evenly. Although the surface is dried, the inside is still wet. Some sulfonated polysulfones do not meet the use requirements, are not easy to store, and have many side reactions during use, and may even have some safety hazards.

[0005] Therefore, in view of the current problems of low drying efficiency and uneven drying of sulfonating agents, a more reasonable solution needs to be proposed to solve the current technical problems. Utility Model Content

[0026] The upper area of ​​the reactor 1 is provided with a feeding port 11, and the lower area is provided with a discharge port 12; the reactor 1 is provided with a second spiral stirring device 13 for stirring the material 9, and the bottom is provided with a second heating device for heating the material 9; the bottom of the drying tank 3 is provided with a heat exchange device 31 for heat exchange with the material 9; the drying tank 3 is connected to the exhaust fan 6, and the bottom of the drying tank 3 is provided with a guide port 32.

[0027] In the above scheme, the reactor 1 is used as the main container for the sulfonation reaction. The second spiral stirring device 13 arranged inside can fully stir the material 9 to ensure the uniformity of the sulfonation reaction. The second heating device at the bottom is used for heating to start and maintain the temperature required for the sulfonation reaction. The closed structure of the spiral discharging machine 2 helps to control the reaction environment and prevent the contamination and loss of the material 9 during the drying process. The first spiral stirring device 23 arranged in the spiral discharging machine 2 can push the material 9 from the feed port 21 to the discharge port 22 to ensure the continuous flow of the material 9 and the progress of the reaction. The first heating device is used to heat the material 9 to maintain the required reaction temperature and dry the material 9.

The pulverizer 5 is used to pulverize the material 9 transferred by the elevator 4 to obtain a sulfonated agent product of a desired particle size.

[0028] Through the above technical solution, the material 9 (sulfonating agent) can be dried continuously. By continuously stirring the material 9 during the drying process and drying it multiple times to different degrees, the drying efficiency of the sulfonating agent is guaranteed, and the sulfonating agent is helped to be dried evenly, so that the dried sulfonating agent is easier to carry out subsequent processing steps such as crushing, mixing and packaging, thereby improving the continuity and automation of the production process. Through the optimization of the closed structure and heat exchange efficiency, the emission of pollutants and the waste of energy are reduced, and the automation and continuity of the sulfonating agent production are realized, the drying efficiency and product quality are improved, and the energy consumption and labor costs are reduced.

[0029] By effectively drying the moisture of the sulfonating agent, the purity and reaction efficiency of the sulfonating agent can be ensured, and the hygroscopicity of the sulfonating agent or chemical changes caused by moisture can be reduced, thereby improving its stability and extending the storage and service life. In the sulfonation reaction, the presence of moisture may affect the reaction rate and the quality of the product. By drying to control the moisture content of the sulfonating agent, the reaction conditions can be precisely controlled. Some sulfonating agents may undergo dangerous reactions in a humid environment, and drying helps to reduce this risk and improve the safety of operation. The dried sulfonating agent can react with the reactants faster due to its low moisture content, thereby improving the efficiency of the sulfonation reaction. In addition, drying can reduce side reactions caused by moisture, such as sulfone compounds that may be generated during the sulfonation process, and ensure product quality. For some sulfonating agents, such as sulfonated carbon materials, drying can improve their pore structure and surface acidity, thereby improving their catalytic performance as solid acids.

In this way, the gantry can move along the guide rail, so as to approach or move away from the outlet 32. Based on the design of the slide rail and the slider, the slider can be pushed down by the second driver to move along the slide rail, thereby changing the position of the stirring device 82 relative to the bottom of the drying pool 3.

[0031] In this way, the action range of the stirring device 82 can be increased, thereby effectively stirring the material 9 in various areas of the bottom of the drying tank 3. When drying the material 9, the stirring device 82 can rotate inside the drying tank 3 to help the material 9 tumble, ensure more uniform contact and reaction between the sulfonating agent and the material 9, and improve the uniformity and efficiency of the reaction.
