Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, specifically to a chemical reaction vessel that is easy to clean. Background Technology
[0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation, and are now indispensable equipment. After unloading, the inner wall and stirring mechanism of the reactor will have material adhering to them. If not cleaned properly, this can cause production contamination.
[0003] Based on this, CN 222510879 U discloses a chemical reactor that is easy to clean, which includes a reactor body, a reactor cover at the top of the reactor body, a stirring and scraping mechanism at the top of the reactor cover, and a spraying mechanism inside the reactor body; a rotating rod is fixedly installed at the output end of a first motor, a rotating sleeve is fitted on the outer wall of the rotating rod, the top of the rotating sleeve is rotatably installed at the bottom of the reactor cover, a first gear is fixedly installed on the outer wall of the rotating sleeve, a second gear is fixedly installed at the output end of a second motor, the second gear and the first gear are meshed together, two connecting rods are fixedly installed on the outer wall of the rotating sleeve, and scrapers are fixedly installed on the outer walls of both connecting rods. By setting the second motor, the rotation of the scrapers can be controlled at any time to clean the inside of the reactor. However, the following problems exist: 1. The spraying mechanism has a weak cleaning effect on the stirring rod, and cleaning can only be achieved by injecting a large amount of cleaning fluid into the reactor, resulting in a large consumption of cleaning fluid; 2. The cleaning of the inner wall of the reactor is mainly achieved by the scraper, and cleaning the scraper still requires the injection of a large amount of cleaning fluid. In addition, the scraper will still cause wear on the inner wall of the reactor after long-term use. Utility Model Content
[0004] The purpose of this invention is to provide a chemical reactor with a reasonable structure, reliable use, and easy cleaning that solves the above-mentioned problems. On the one hand, it ensures the cleaning effect on the inner wall of the reactor and its internal stirring mechanism, and on the other hand, it greatly reduces the consumption of cleaning solution and also greatly reduces the wear on the inner wall of the reactor.
[0005] The technical solution of this utility model is:
[0006] A chemical reactor that is easy to clean includes a reactor body, a stirring paddle located inside the reactor body, and an annular water distribution pipe built into the top of the reactor body. The key technical features are: an inner nozzle assembly is provided on the inner ring surface of the annular water distribution pipe; an annular brush body is fixed on the outer ring surface of the annular water distribution pipe, and an external spray hole assembly leading to the annular brush body is provided on the outer ring surface; a flexible annular scraper is fixed above the annular brush body on the annular water distribution pipe; four longitudinal water delivery pipes are evenly arranged on the upper surface of the annular water distribution pipe; guide seats corresponding to the longitudinal water delivery pipes are provided on the top surface of the reactor body; the upper ends of each longitudinal water delivery pipe pass through the guide seats and are connected by an annular guide pipe; the annular guide pipe is also connected to an inlet pipe; longitudinal racks are provided on the outer walls of two symmetrically arranged longitudinal water delivery pipes; and a gear drive structure corresponding to the longitudinal racks is provided on the top of the reactor body.
[0007] The aforementioned easy-to-clean chemical reactor, wherein the gear drive structure includes a drive motor reducer fixed to the top of the reactor body, and a drive gear fixed to the output shaft of the drive motor reducer and meshing with a longitudinal rack.
[0008] In the aforementioned easy-to-clean chemical reactor, the center line of the nozzle of the inner nozzle assembly forms an acute angle with the horizontal plane.
[0009] The beneficial effects of this utility model are:
[0010] 1. The inner ring surface of the annular water distribution pipeline is equipped with an inner nozzle assembly, which is arranged facing the agitator. During the downward movement of the longitudinal water supply pipeline, the annular water distribution pipeline, and the inner nozzle assembly using the gear drive structure, the agitator motor drives the agitator to rotate and cooperate. The inner nozzle assembly sprays and cleans the agitator, resulting in good cleaning effect and saving cleaning fluid.
[0011] 2. An annular brush body is fixed on the outer ring surface of the annular water distribution pipe. The annular brush body is connected to the inner wall of the reactor body. The spray liquid can be delivered to the annular brush body through the external spray hole group. During the downward movement of the annular water distribution pipe, the dual action of the annular brush body and the cleaning liquid achieves effective cleaning of the inner wall of the reactor body. At the same time, during the downward movement of the annular water distribution pipe, the flexible annular scraper scrapes off the cleaning residue, further improving the cleaning effect and saving cleaning liquid.
[0012] 3. The outer spray hole group on the outer ring surface of the annular water distribution pipe can achieve cleaning of the annular brush body.
[0013] 4. The flexibility of the flexible annular scraper greatly reduces wear on the inner wall of the reactor body. Attached Figure Description

Detailed Implementation
[0018] The present invention will be described in detail with reference to the accompanying drawings.
[0019] like Figures 1-3 As shown, the easy-to-clean chemical reactor includes a reactor body 7, a stirring paddle 8 located inside the reactor body 7, and an annular water distribution pipe 9 built into the top of the reactor body 7. A stirring motor 4 connected to the stirring paddle 8 is located on the top of the reactor body 7.
[0020] The annular water distribution pipe 9 has an inner nozzle assembly 12 on its inner ring surface, and the center line of the spray nozzle of the inner nozzle assembly 12 forms an acute angle with the horizontal plane. An annular brush body 10 is fixed to the outer ring surface of the annular water distribution pipe 9, and an external spray hole assembly 13 leading to the annular brush body 10 is provided on the outer ring surface. A flexible annular scraper ring 11 is fixed above the annular brush body 10 in the annular water distribution pipe 9.
[0021] The upper surface of the annular water distribution pipe 9 is uniformly provided with four longitudinal water supply pipes 3. The top surface of the reactor body 7 is provided with a guide seat 6 corresponding to the longitudinal water supply pipe 3. The upper ends of each longitudinal water supply pipe 3 pass through the guide seat 6 and are connected by an annular guide pipe 2. The annular guide pipe 2 is also connected to the water inlet pipe 1.
[0022] Two symmetrically arranged longitudinal water supply pipes 3 are provided with longitudinal racks 14 on their outer walls, and the top of the reactor body 7 is provided with a gear drive structure corresponding to the longitudinal racks 14. In this embodiment, the gear drive structure includes a drive motor reducer 15 fixed to the top of the reactor body 7 and a drive gear 5 fixed to the output shaft of the drive motor reducer 15 and meshing with the longitudinal racks 14.
[0023] Working principle:
[0024] When the reactor is operating normally, the annular water distribution pipe 9 is located on the top inner side of the reactor body 7 and is not located in the reactants. Therefore, contact with the reactants is avoided.
[0025] After the reaction is completed and the material is unloaded, the drive motor reducer 15 is started, driving the four longitudinal water supply pipes 3, the annular water distribution pipe 9, the annular brush body 10, the flexible annular scraper ring 11, and the inner nozzle group 12 to move downwards synchronously. During the downward movement, the cleaning fluid enters the annular guide pipe 2 through the water inlet pipe 1, and then is delivered to the inner nozzle group 12 and the outer spray hole group 13 through the four longitudinal water supply pipes 3 and the annular water distribution pipe 9. During the downward movement, the inner nozzle group 12 sprays and cleans the stirring paddle 8. To ensure the cleaning effect, the stirring paddle 8 rotates under the drive of the stirring motor 4 to achieve all-round cleaning. During the downward movement of the annular brush body 10 and the flexible annular scraper ring 11, the outer spray hole group 13 delivers the cleaning fluid to the annular brush body 10, achieving cleaning and rinsing of the inner wall of the reactor body 7. The cleaning effect is good, and the cleaning fluid is saved at the same time.
[0026] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
