Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction kettles, in particular to a discharge auxiliary wall scraping structure of a crystallization kettle. Background Art

[0002] The crystallization kettle is a crystallization equipment that needs to cool down the interlayer with chilled water or refrigerant water rapidly after the material is mixed and reacted. The key links are the size of the interlayer area, the structure of the agitator and the material outlet form, the high-precision polishing of the tank body, and the requirement of no dead corners in the tank body cleaning to meet the process conditions. The crystallized material is attached to the inner wall of the kettle in a large amount in the form of a crystal structure, which affects the discharge of the crystallization kettle material.

[0003] After searching, the application number CN201920722913.2 discloses an ammonium perchlorate continuous crystallization system, including a crystallization kettle body, in which a first and a second stirring shaft are provided, and a plurality of groups of first and second stirring blades are respectively installed on the first and second stirring shafts, and the bottom of the crystallization kettle is connected to a screw conveying device through a discharge pipe, and a rotating discharge device is arranged in the discharge pipe, thereby reducing the phenomenon of blockage between the discharge port of the crystallization kettle and the feed port of the conveying device.

[0004] The existing auxiliary discharge structure stirs the inside of the throwing pipe to prevent the material from being blocked in the pipe. However, a large amount of product adheres to the wall of the kettle after crystallization and cannot fall off by itself, which not only reduces the output rate of the product and causes material waste, but also increases the difficulty of cleaning the kettle body in the later stage. Utility Model Content

[0005] The utility model aims to provide a discharging auxiliary scraping wall structure of a crystallization kettle to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a discharging and auxiliary scraping structure of a crystallization kettle, comprising a crystallization kettle with a bracket at the bottom, a stirring assembly installed inside the crystallization kettle, the stirring assembly comprising a motor installed on the top of the crystallization kettle, the output end of the motor extends to the inner cavity of the crystallization kettle and is fixedly connected to a stirring shaft, a plurality of groups of scraping assemblies are fixedly connected to the outer wall of the stirring shaft at circumferential intervals, the scraping assembly comprises two groups of stirring sleeves fixedly connected to the outer wall of the stirring shaft at vertical intervals, a sliding rod is slidably connected in the stirring sleeve, and a scraping plate is fixedly connected to the two groups of sliding rods at one end away from the stirring sleeve, and the motor drives the scraping plate to scrape the inner wall of the crystallization kettle after crystallization to assist in discharging.

[0007] As a further preference, two groups of the stirring sleeves are fixedly connected to the lower two-thirds region of the stirring shaft, and the shape of the scraper plate fits the inner cavity of the crystallization kettle.

[0008] As a further preference, an adjustment component is installed on the side wall of the stirring sleeve that is tangent to the rotation direction, and the adjustment component selectively controls the sliding of the inner wall of the stirring sleeve by the sliding rod eye.

[0009] As a further preference, the adjustment assembly includes a streamlined protrusion, one end of which is fixedly connected to a mounting rod, the mounting rod passes through the side wall of the stirring sleeve and is symmetrically fixedly connected to two groups of supporting spring plates, one group of the supporting spring plates is hingedly connected to the side wall of the inner cavity of the stirring sleeve, and the other group of the supporting spring plates is hingedly connected to the side wall of the sliding rod near one end of the stirring sleeve.

[0010] As a further preference, the mounting rod is located on the outer wall of the inner cavity portion of the stirring sleeve and is fixedly connected to a limiting ring.

[0011] As a further preference, an elastic pad is fixedly connected to one side of the scraper plate close to the inner wall of the crystallization kettle.

[0012] Through the above technical solution, the discharge auxiliary scraping structure of the crystallization kettle provided by the utility model has the following benefits:

[0013] The utility model provides a stirring assembly, and a motor drives the stirring shaft to drive the stirring sleeve to rotate, so as to stir the materials in the crystallization kettle horizontally. At the same time, the sliding rod restricted by the regulating assembly in the stirring sleeve rotates with the stirring sleeve, and drives the scraper plate to stir the materials in the kettle longitudinally to improve the uniformity of mixing.

[0014] At the same time, after the material crystallizes, the crystallized material pushes the streamlined convex rod to move toward the inner cavity of the stirring sleeve when the stirring sleeve rotates, so that the mounting rod pushes the two sets of supporting springs. After the supporting springs are subjected to force, they are deformed and push the sliding rod to move to the side away from the inner cavity of the stirring sleeve. The sliding rod pushes the scraper plate to fit the inner wall of the crystallization kettle. The scraper plate rotating with the sliding rod scrapes off the crystallized material attached to the inner wall of the crystallization kettle, thereby improving the discharge efficiency of the crystallization kettle. As the crystallized material is discharged, the thrust on the streamlined convex rod gradually decreases, the supporting springs gradually return to their original state, pulling the sliding rod to move toward the inner cavity of the stirring sleeve, and the scraper plate gradually moves away from the inner wall of the crystallization kettle, thereby avoiding excessive friction between the scraper plate and the inner wall, thereby reducing the service life of the scraper plate and the crystallization kettle.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model will be further described in detail in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1 - Figure 5 , which is a discharging auxiliary scraping wall structure of the crystallization kettle provided by the present utility model, including a crystallization kettle 1 and a stirring component 2.

[0024] Among them, please refer to Figures 1 to 3 , the stirring component 2 includes a motor 21 installed on the top of the crystallization kettle 1. The output shaft of the motor 21 penetrates through the upper end face of the crystallization kettle 1 and is fixedly connected with a stirring shaft 22. A plurality of groups of scraping wall components 23 are circumferentially and spacedly installed on the side wall of the stirring shaft 22. When the motor 21 works, it drives the stirring shaft 22 to rotate, driving a plurality of groups of scraping wall components 23 to stir the materials in the inner cavity of the crystallization kettle 1.

[0025] It should be added that a feeding port and a discharging port are respectively arranged at the top and bottom of the crystallization kettle 1. The crystallization kettle 1 is provided with a sandwich, and a coolant inlet and outlet pipe is arranged on the side wall of the crystallization kettle 1. Coolant is conveyed into and replaced in the sandwich through the coolant inlet and outlet pipe to ensure that the materials in the inner cavity of the crystallization kettle 1 reach the crystallization temperature.

[0026] Please refer to Figure 4 and Figure 5 , the scraping wall component 23 includes two groups of stirring sleeves 232 fixedly connected to the outer wall of the stirring shaft 22 at intervals in the vertical direction. A sliding rod 233 is slidably connected to the inner cavity of one end of the stirring sleeve 232 away from the stirring shaft 22. The two sliding rods 233 are fixedly connected to a scraping wall plate 234 at one end away from the stirring sleeve 232. An adjustment component 231 is installed on one side tangent to the rotation direction, and the adjustment component 231 selectively controls the movement of the sliding rod 233 in the stirring sleeve 232.

[0027] It should be noted that the shape of the scraper plate 234 fits the inner wall of the crystallization kettle 1 , and an elastic pad is fixedly connected to the scraper plate 234 on one side close to the inner wall of the crystallization kettle 1 .

[0028] It should also be noted that the installation height of the two sets of stirring sleeves 232 does not exceed the two-thirds height area of the lower end of the stirring shaft 22, and the material filling height in the crystallization kettle 1 is not lower than the installation height of the stirring sleeves 232.

[0029] Specifically, the adjustment component 231 includes a streamlined protrusion 2311, one end of which is fixedly connected to a mounting rod 2312, the mounting rod 2312 is symmetrically fixedly connected to the side wall of the stirring sleeve 232 at one end away from the streamlined protrusion 2311 and penetrates the side wall of the stirring sleeve 232 with two groups of supporting spring plates 2313, the supporting spring plates 2313 are rotatably connected to the end of the mounting rod 2312 away from the mounting rod 2312 with an articulated shaft 2315, one group of articulated shafts 2315 are rotatably connected to the side wall of the stirring sleeve 232, and the other group of articulated shafts 2315 are rotatably connected to the side wall of the sliding rod 233 near one end of the stirring sleeve 232, and the mounting rod 2312 is located on the outer wall of the inner cavity of the stirring sleeve 232 and is fixedly connected to a limiting ring 2314.

[0030] It should be noted that when the stirring sleeve 232 stirs the material before crystallization, the streamlined protruding rod 2311 is subject to less liquid resistance due to its streamlined shape. At this time, the mounting rod 2312 is completely located in the inner cavity of the stirring sleeve 232, and the scraper plate 234 does not contact the inner wall of the crystallization kettle 1.

[0031] It can be understood that the motor 21 drives the stirring sleeve 232 to rotate through the stirring shaft 22, and the sliding rod 233 is supported by the supporting spring 2313 to drive the scraper plate 234 to rotate with the stirring sleeve 232. At the same time, the limiting ring 2314 limits the mounting rod 2312 to prevent the mounting rod 2312 from excessively extending out of the stirring sleeve 232, thereby providing sufficient supporting force for the sliding rod 233 to rotate and stir, so that the scraper assembly 23 stirs the material in both horizontal and vertical dimensions. After the stirring is completed, the material begins to crystallize. When the material is crystallized, the motor 21 is driven by the stirring shaft 2 The stirring sleeve 232 is driven to rotate, and the crystallized material generates a thrust on the streamlined convex rod 2311 rotating with the stirring sleeve 232. The thrust pushes the streamlined convex rod 2311 to move into the stirring sleeve 232, thereby pushing the two sets of supporting springs 2313 to deform. The deformed supporting springs 2313 push the sliding rod 233 away from the stirring sleeve 232, thereby controlling the scraper plate 234 to be in close contact with the inner wall of the crystallization kettle 1. At this time, the scraper plate 234 rotating with the stirring sleeve 232 scrapes off the crystallized material attached to the inner wall of the crystallization kettle 1, thereby promoting the discharge of the material in the kettle to the discharge port.

[0032] Principle: Through the feed inlet, raw materials are put into the inner cavity of the crystallization kettle 1. The motor 21 works to drive the stirring shaft 22 to rotate, driving the scraping wall assembly 23 to mix and stir the materials. Open the coolant inlet pipe to transport coolant into the jacket of the crystallization kettle 1 and control the flow of the coolant in the jacket to provide the required cooling temperature for the raw materials in the inner cavity of the crystallization kettle 1. When the motor 21 stops working, after the raw materials are crystallized, the motor 21 drives the stirring sleeve 232 to rotate again through the stirring shaft 22 to stir the crystallized materials in the kettle. At the same time, the thrust generated by the crystallized materials pushes the streamlined convex rod 2311 to push the mounting rod 2312 to move into the inner cavity of the stirring sleeve 232, causing the supporting spring piece 2313 to deform and push the sliding rod 233 to move away from the stirring sleeve 232, so as to control the scraping wall plate 234 to be close to the inner wall of the crystallization kettle 1. At this time, the scraping wall plate 234 following the rotation of the stirring sleeve 232 scrapes off the crystallized materials attached to the inner wall of the crystallization kettle 1, promoting the discharging of the crystallization kettle. As the crystallized materials gradually decrease, the pushing force received by the streamlined convex rod 2311 decreases, and the deformed supporting spring piece 2313 controls the sliding rod 233 to move towards the stirring sleeve 232, and the scraping wall plate 234 moves away from the inner wall of the crystallization kettle 1 to avoid affecting the service life of the scraping wall plate 234 and the crystallization kettle 1 due to long-term friction.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
