Description

Technical Field

[0001] This utility model relates to the field of chloroacetic acid resin production technology, and in particular to a drying mechanism for continuous production of chloroacetic acid resin with a dispersing and crushing device. Background Technology

[0002] Chlorinated vinyl acetate resins are typically dried using airflow drying equipment, a continuous drying system that utilizes high-speed hot airflow to rapidly dry wet materials. The drying medium dries solid particles in a fluidized state, essentially through the boiling of the powder. During drying, the gas and solid phases come into countercurrent contact and are violently agitated. The solid particles are suspended in the drying medium, resulting in a large contact surface area and excellent performance in heat transfer, mass transfer, volumetric drying intensity, and thermal efficiency. It is widely used in the chemical, food, pharmaceutical, feed, and mining industries. Its core principle is the rapid evaporation and removal of moisture from the material through direct contact between hot air and the material. Due to its adaptability to various materials, small footprint, large production capacity, high thermal efficiency, easy operation control, and low particle breakage, it is widely used in large-scale chemical production. The continuous production drying mechanism for vinyl chloride-vinyl acetate copolymer resin includes drying devices such as a limiting tank, drying plate, servo motor one, striking rod, drying lamp, and moving plate. It also includes an extraction pipe, servo motor two, rotating rod two, and conveyor belt. The sedimentation tank contains a treatment device for alkali treatment of the vinyl chloride-vinyl acetate copolymer resin. Additionally, it may be equipped with a structure similar to a dispersant, including a high-speed rotating rotor. The main function of this drying mechanism is to react and polymerize the raw materials through components such as the reaction vessel and polymerization vessel. After alkali treatment in the sedimentation tank, the vinyl chloride-vinyl acetate copolymer resin is dehydrated and dried using the drying device in the drying chamber. Simultaneously, the dispersant crusher impacts and shears the agglomerated material, pulverizing and reducing it to ensure the drying effect and quality of the material, thus achieving continuous production of vinyl chloride-vinyl acetate resin. Airflow drying devices are typically cylindrical structures, offering advantages such as high single-unit capacity, low energy consumption, high automation, minimal human intervention, and low equipment and civil engineering investment. However, they can only dry small, uniformly sized particles with good flowability. They struggle to handle materials that are prone to sticking and have poor flowability. Due to the structural characteristics of airflow drying systems, in traditional production processes, materials are usually fed via a screw conveyor. During the pushing process by the screw blades, materials, especially those with stickiness and a tendency to accumulate, easily agglomerate, reducing drying efficiency and affecting finished product quality. The impact on the thermal stability of the material is particularly significant. To address these issues, a continuous production drying mechanism for chloroacetic acid resin with a dispersing and crushing device is proposed. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 This utility model provides an embodiment of a continuous production drying mechanism for chloroacetic acid resin with a dispersing and crushing device. The mechanism includes a drying chamber 5, which serves as the main space of the entire mechanism, providing a closed working environment for the drying and crushing process of the chloroacetic acid resin. One end of the drying chamber 5 has an air inlet 1 for introducing hot air or a drying medium to provide the airflow required for drying. The other end of the drying chamber 5 has an air outlet 8 for discharging moisture and waste gas generated during the drying process, maintaining airflow circulation within the drying chamber 5. A crusher 3 is fixedly connected to the inside of the drying chamber 5, used to disperse and crush any chloroacetic acid resin that may clump during the drying process, ensuring uniform drying of the material.

[0018] Reference Figure 1 Temperature measuring point 6 is fixedly connected to the outside of the drying chamber 5. Temperature measuring point 6 can monitor the temperature change inside the drying chamber 5 in real time and provide data support for adjusting the drying conditions. Feed screw 4 is fixedly connected to the left side of the crusher 3. Feed screw 4 is responsible for continuously and evenly conveying the chloroacetic acid resin raw material to be dried into the drying chamber 5.

[0019] Reference Figure 1 Multiple cleaning holes 2 are provided on the outside of the drying chamber 5. These cleaning holes 2 facilitate operators to regularly clean and maintain the inside of the drying chamber 5 to prevent residual materials from affecting subsequent production.

[0020] Reference Figure 1 A pressure measuring point 7 is fixedly connected to the outside of the drying chamber 5. The pressure measuring point 7 can monitor the air pressure inside the drying chamber 5 in real time to ensure that the equipment operates within a safe pressure range.

[0021] Reference Figure 1The air inlet 1 and the air outlet 8 are connected. This connection structure allows the drying medium to form a complete flow path inside the drying chamber 5, ensuring that the drying process continues effectively.

[0022] Reference Figure 1 The feeding screw auger 4 is fixedly connected to the inside of the drying chamber 5. This connection method allows the feeding screw auger 4 to directly feed the material into the core working area of ​​the drying chamber 5, thereby improving the feeding efficiency.

[0023] Reference Figure 1 Temperature measuring point 6 is located to the right of pressure measuring point 7. This layout facilitates the monitoring of temperature and pressure parameters in different areas of the drying chamber 5, allowing for a more comprehensive understanding of the equipment's operating status.

[0024] Reference Figure 1 A cleaning cover is installed on the front side of the cleaning hole 2. The cleaning cover can seal the cleaning hole 2 during equipment operation to prevent the drying medium from leaking and external impurities from entering, and ensure the airtightness of the drying chamber 5.

[0025] Working Principle: When the continuous production and drying mechanism of the chloroacetic acid resin in this crushing and dispersing device is working, the chloroacetic acid resin raw material to be dried is first continuously and evenly conveyed into the drying chamber 5 through the feeding screw auger 4. Then, the hot air or drying medium required for drying enters the chamber through the air inlet 1. Under the structure of the air inlet 1 and the air outlet 8 being connected, the drying medium forms a stable flow path in the drying chamber 5, continuously contacting the chloroacetic acid resin material to remove moisture. At the same time, the moisture and waste gas generated during the drying process are discharged through the air outlet 8 at the other end of the drying chamber 5. The crusher 3, which is fixedly connected to the inside of the drying chamber 5, will break up and crush any caking chloroacetic acid resin that may occur during the drying process in real time, ensuring that the material is always in a uniformly dispersed state to improve drying efficiency and effect. The temperature measuring point 6, which is fixedly connected to the outside of the drying chamber 5, will monitor the internal temperature of the chamber in real time, while the pressure measuring point 7 will monitor the internal air pressure of the chamber simultaneously. When the equipment needs regular maintenance, the operator can open the cleaning cover installed on the front of the cleaning hole 2 and clean the inside of the chamber through the multiple cleaning holes 2 opened on the outside of the drying chamber 5 to prevent residual material from affecting subsequent production.
