Abstract
Description
Technical Field
[0001] This technical solution relates to the field of filter washing and drying equipment technology, specifically referring to a scraped-wall reaction vessel. Background Technology
[0002] A reaction vessel (or reactor) is a core process device used to carry out chemical or physical reactions. It is commonly found in many industrial fields such as chemical, pharmaceutical, petroleum, food, dye, pesticide, and scientific research. A reaction vessel is a closed container designed to allow materials (raw materials) to undergo chemical reactions or physical changes (such as mixing, dissolving, emulsifying, polymerizing, crystallizing, etc.) under specific temperature, pressure, and stirring conditions to produce the desired products or intermediates.
[0003] Existing reactors require stirring of materials (suspensions) during operation. During the stirring process, some materials may adhere to the inner wall of the reactor, resulting in material loss or contamination of other materials when processing them again. Summary of the Invention
[0004] The purpose of this technical solution is to provide a scraped-wall reactor, which solves the problem of material adhering to the inner wall of the tank by adding a scraping part to the stirring mechanism.
[0005] The purpose of this technical solution is achieved as follows:
[0006] A scraped-wall reactor includes: a vessel body having an internal receiving chamber, the vessel body also having a feed inlet and a discharge outlet; a stirring mechanism disposed on the vessel body and partially extending into the receiving chamber for stirring a mixture containing materials; a filtration mechanism disposed within the vessel body for filtering the mixture; and a heating mechanism disposed on the vessel body for heating the mixture or drying the materials.
[0007] The stirring mechanism includes: a driving component with a turntable at its output end; a wall scraper with its upper end on the turntable and its lower end movably abutting against the inner wall of the vessel; and a stirring component on the turntable. When the driving component drives the turntable to rotate, the wall scraper can clean the inner wall of the vessel, and the stirring component can stir the mixture.
[0008] Preferably, a scraper is provided on one side of the lower end of the scraper section, and the scraper is made of a flexible material.
[0009] Preferably, the upper end of the scraping section can sway under the action of external force; the other side of the lower end of the scraping section has a flow guiding slope, which is used to make the scraping section always have a tendency to move close to the inner wall of the vessel during operation.
[0010] Preferably, the middle part of the scraping section is arranged along the tangential direction of its rotation.
[0011] Preferably, the vessel body has an outer shell and an inner liner, with an installation space formed between the outer shell and the inner liner; the heating mechanism is disposed within the installation space, and the heating mechanism includes a plurality of heaters, all of which are arrayed within the installation space.
[0012] The key and beneficial technical effects of this technical solution compared to existing technologies are:
[0013] 1. The stirring mechanism designed in this technical solution includes a stirring section for stirring the mixture and a scraping section for cleaning the inner wall of the vessel. The driving component controls both the stirring section and the scraping section simultaneously, which can save energy. In this way, while stirring the material, the scraping section can simultaneously clean the inner wall of the vessel, causing the material adhering to the inner wall of the vessel to fall off, making the material more fully mixed, thereby avoiding material loss. Moreover, it can ensure the cleanliness of the vessel and prevent residual material from contaminating the material to be processed next.
[0014] 2. The drive component designed in this technical solution can rotate forward or backward, and the upper end of the scraping part can wobble slightly. The scraping part has a flow-guiding slope, which can reduce the resistance encountered by the scraping part during forward or reverse rotation. Furthermore, during the operation of the scraping part, the pressure of the scraping part on the inner wall of the vessel is directed towards the inner wall of the vessel through the flow-guiding slope. This allows the scraping part to better adhere to the inner wall of the vessel for cleaning, thereby improving the quality of cleaning the inner wall of the vessel.
[0015] 3. The scraping part designed in this technical solution makes a circular motion during operation. The middle part of the scraping part is set along the tangent of its rotation. This can reduce the resistance of its movement in the mixture, thereby saving energy. At the same time, it can also prevent the scraping part from being damaged due to excessive resistance, thus improving the service life of the product. Attached Figure Description

[0021] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.
[0022] like Figure 1 As shown, a scraped-wall reactor includes a vessel body 1, a stirring mechanism 5, a filtering mechanism 6, and a heating mechanism 7. The vessel body 1 is hollow to form a receiving chamber 2. The vessel body 1 also has a feed inlet 3 and a discharge outlet 4. During processing, the material can be added into the vessel body 1 first, and then a solvent can be injected for mixing. Alternatively, a mixture of materials can be added directly.
[0023] The stirring mechanism 5 is partially mounted on the vessel body 1 and partially extends into the receiving chamber 2. The stirring mechanism 5 is used to stir the mixture containing materials to fully dissolve or homogenize the mixture. The filtration mechanism 6 is mounted inside the vessel body 1 and is used to filter the mixture, allowing the solution containing impurities to flow out and leaving the desired material. The heating mechanism 7 is mounted on the vessel body 1 and is used to heat the mixture or dry the materials. Some processing steps require increasing the temperature to fully dissolve the materials. After filtering the solution containing impurities, the heating mechanism 7 can heat and dry the materials.
[0024] like Figure 2-4 As shown, the stirring mechanism 5 includes a driving component 8, a turntable 9, a wall scraping part 10, and a stirring part 11. The driving component 8 is located above the vessel body 1 and is a drive motor that can rotate forward or backward. The turntable 9 is located at the output end of the driving component 8 and can rotate with the driving component 8. The upper end of the wall scraping part 10 is connected to the center of the turntable 9 and can also rotate with the turntable 9. The upper end of the stirring part 11 is connected to the center of the turntable 9 and can rotate synchronously with the wall scraping part 10 and follow the turntable 9.
[0025] Specifically, the upper part of the scraping section 10 is S-shaped, and the lower part is vertical. A flexible scraper 12 is provided on one side of the lower part. The scraper 12 can be slightly deflected during operation and is always in contact with the inner wall of the vessel body 1 to complete the task of cleaning the inner wall of the vessel body 1. When the turntable 9 drives the scraping section 10 to make a circular motion, the scraper 12 can clean all the inner walls of the vessel body 1.
[0026] Furthermore, the "S"-shaped portion of the upper part of the scraper 10 can slightly sway under external force to ensure that the scraper 12 always adheres to the inner wall of the vessel 1. The other side of the lower part of the scraper 10 is provided with a flow-guiding slope 13. When the scraper 10 rotates in the mixture, the mixture will exert a force on the scraper 10 towards the inner wall of the vessel 1 through the flow-guiding slope 13, so that the scraper 12 adheres to the inner wall of the vessel 1. At the same time, the flow-guiding slope 13 also has the effect of guiding and depressurizing, avoiding direct collision between the scraper 10 and the mixture, reducing its motion resistance, and effectively preventing the scraper 10 from breaking. The middle part of the scraper 10 is arranged along the tangent of its rotation. The middle part of the scraper 10 is a connecting part. The connecting part does not bear the function of cleaning the inner wall of the vessel 1, so it is set to be flat to reduce the motion resistance of the scraper 10 in the mixture.
[0027] like Figure 1 As shown, the vessel body 1 has an outer shell 14 and an inner liner 15, and an installation space is formed between the outer shell 14 and the inner liner 15. The heating mechanism 7 is disposed in the installation space. The heating mechanism 7 includes a plurality of heaters 16, and all heaters 16 are arrayed in the installation space. The heaters 16 are used to heat the mixture or dry the material. The heaters 16 are disposed in the installation space to ensure their cleanliness and increase the heat transfer efficiency.
[0028] [Variation Example]
[0029] The heating mechanism 7 includes several heaters 16, all of which are located on the outer wall of the vessel body 1.
