Abstract
Description
Technical Field
[0001] This utility model belongs to the field of distillation kettle technology and relates to a material collection device for distillation kettle residue. Background Technology
[0002] In industries such as chemical manufacturing, petroleum refining, and food processing, distillation is a crucial process for separating mixtures. The distillation vessel, an indispensable piece of equipment in the distillation process, is primarily used to separate components with different boiling points through heating. Its working principle is based on the different volatility of the components in a liquid mixture. Under heating conditions, lower-boiling-point components readily vaporize, while higher-boiling-point components remain relatively in the liquid phase. As the vapor rises and passes through the packing or trays, multiple processes of partial condensation and partial evaporation occur, thus achieving effective separation. Finally, the target product is collected from the top or side stream of the column, while the remaining material, including unvolatile heavy components and reaction byproducts, remains at the bottom of the vessel.
[0003] As the production process continues, a certain amount of residue accumulates at the bottom of the distillation vessel, known as "distillation vessel residue." This residue typically has high viscosity and, due to the high-temperature, high-pressure working environment, may adhere tightly to the vessel walls and bottom structure. This not only increases the difficulty of cleaning but, if not thoroughly cleaned, the residue may affect the separation efficiency in subsequent operations and even negatively impact product quality. Furthermore, the presence of residue can exacerbate equipment corrosion, shortening the service life of the distillation vessel. Currently, traditional cleaning methods for distillation vessel residue often rely on manual washing or mechanical scraping devices, but these methods suffer from low efficiency, high labor intensity, and poor cleaning results. Utility Model Content
[0004] The purpose of this invention is to provide a device for collecting residues from a distillation vessel, which can automatically clean the residues in the distillation vessel, reduce manual labor intensity, and achieve good cleaning results.
[0005] To solve the above-mentioned technical problems, this utility model provides a material collection device for distillation kettle residue, including a kettle body, the lower part of which is a conical section, and a drive motor installed at the upper end of the kettle body. The power output shaft of the drive motor is connected downward to a stirring shaft extending into the kettle body. The stirring shaft is characterized in that an inner wall scraper is connected to the outer periphery of the stirring shaft through a connecting strip, and the inner wall scraper contacts the inner wall of the kettle body. A bottom scraper that cooperates with the inner wall of the conical section is connected to the lower part of the stirring shaft through a connecting strip, and the bottom scraper contacts the inner wall of the conical section. A slag discharge pipe is provided downward at the lower end of the conical section, and a rotating shaft extending into the slag discharge pipe is connected downward to the stirring shaft.
[0006] The upper end of the slag discharge pipe has two outwardly facing storage sleeves on opposite sides. Each storage sleeve has a horizontally opening horizontal sliding cavity that communicates with the inside of the slag discharge pipe. The outer end of each storage sleeve has a threaded adjustment hole that communicates with the corresponding horizontal sliding cavity. Each storage sleeve has a slidably connected sealing slide. The outer edge of each sealing slide is rotatably connected to a threaded adjustment shaft that is outwardly positioned and threadedly connected to the corresponding threaded adjustment hole. Each threaded adjustment shaft extends out of the corresponding threaded adjustment hole and has a first knob. Each sealing slide has a C-shaped rotating groove on the side away from the corresponding first knob that cooperates with the rotating shaft for sealing and rotatable connection. The rotating shaft has a spiral conveying blade below the sealing slide.
[0007] By adopting the above technical solution, when it is necessary to discharge residues with high viscosity, first turn the first knob to drive the threaded adjustment shaft to rotate and pull the sealing slide outward, so that the upper opening of the slag discharge pipe is opened. Then start the drive motor, so that the stirring shaft drives the inner wall scraper and the bottom scraper to gradually scrape off the residues on the inner wall of the vessel and the inner wall of the conical section, and let them fall into the slag discharge pipe. The rotating shaft causes the spiral conveying blades to discharge the internal residues downward. Finally, add water or detergent to rinse.
[0008] The present invention is further configured such that a drain pipe is obliquely downwardly arranged at the lower end of the conical section and communicates with it, and an outlet pipe is arranged downwardly in the middle of the drain pipe. The part of the drain pipe outside the outlet pipe is a threaded connection section with internal threads. A sealing shaft that is detachably connected to the inner wall of the drain pipe is provided. A threaded connection shaft that is threadedly connected to the threaded connection section is provided at one end of the sealing shaft that is outwardly arranged. The threaded connection shaft extends out of the drain pipe and is connected to a second knob.
[0009] By adopting the above technical solution, when it is necessary to discharge the liquid with good fluidity from the vessel, the sealing slide and the rotating shaft should be kept in a sealed connection. The second knob should be turned so that the spiral connecting shaft rotates outward, which drives the sealing shaft to move outward, so that the drain pipe and the outlet pipe are connected, and the liquid in the vessel can flow out along the drain pipe and the outlet pipe.
[0010] The present invention is further configured such that a rubber sealing end is connected to the end of the sealing shaft away from the threaded connection shaft.
[0011] The present invention is further configured such that both the inner wall scraper and the bottom scraper are spiral-shaped.
[0012] The present invention is further configured such that each C-shaped rotating groove has an inwardly formed C-shaped sealing groove on its inner wall, and a sealing ring that cooperates with the C-shaped sealing groove is provided on the outer side of the rotating shaft.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] Firstly, this utility model automatically scrapes off the adhering substances on the inner wall of the vessel by automatically scraping them off, and automatically discharges them downwards along the slag discharge pipe, reducing the intensity of manual labor and achieving good cleaning effect. At the same time, the inner wall scraper and the bottom scraper can also play a stirring role during the distillation reaction, achieving two goals at once.
[0015] Secondly, when slag discharge is not required, this utility model utilizes a sealing sliding plate to seal and rotate the shaft, preventing the internal raw materials from being discharged from the slag discharge pipe during the distillation reaction.
[0016] Thirdly, this utility model is also equipped with a drain pipe and an outlet pipe specifically designed for discharging liquids with good flowability, making the discharge of liquids from the vessel more convenient. Attached Figure Description
