Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, and in particular to a fluidized bed for drying acrylamide copolymers. Background Technology
[0002] In the entire production process of acrylamide copolymers, the drying process plays a crucial role because the drying effect is directly related to the quality, performance, and subsequent processing applications of the product. If the drying process is not properly controlled, it may lead to problems such as excessive moisture content and uneven particle size, which in turn affects its performance and stability in various fields. Therefore, it must be given high priority.
[0003] Traditional drying methods suffer from problems such as low drying efficiency, unstable product quality, and high energy consumption. Fluidized bed drying technology is widely used due to its advantages such as high heat and mass transfer efficiency and fast drying speed. However, existing fluidized beds for drying acrylamide copolymers still have some shortcomings, such as uneven gas distribution leading to unstable material fluidization, easy agglomeration during the drying process affecting the uniformity of product particle size, and the need to improve heat utilization.
[0004] Therefore, this invention proposes a fluidized bed for drying acrylamide copolymers. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a fluidized bed for drying acrylamide copolymers.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fluidized bed for drying acrylamide copolymers, comprising:
[0007] A conveying assembly comprises a protective cover and two upright plates, which are respectively disposed at both ends of the protective cover. A base plate is disposed at the bottom of the protective cover and the upright plates. A mounting frame is disposed inside the base plate of the protective cover. A vibrating plate is disposed above the mounting frame. A mounting plate is disposed on the base plate below the vibrating plate. There are two mounting plates in total, and a connecting shaft is rotatably connected between the two mounting plates. A second drive motor is disposed on one of the mounting plates, and the output end of the second drive motor is connected to the connecting shaft. An eccentric roller is disposed on the connecting shaft, and the eccentric roller contacts the bottom of the vibrating plate. A rotating shaft is rotatably connected between the two upright plates, and a blade is disposed on the rotating shaft. A first drive motor is disposed on one of the upright plates, and the output end of the first drive motor is connected to the rotating shaft.
[0008] The heating assembly includes a base box disposed at the bottom of the base plate, a heating mechanism fixedly connected inside the base box, an air outlet hood disposed above the heating mechanism inside the base box, and a connecting pipe disposed between the heating mechanism and the air outlet hood.
[0009] In a preferred embodiment, a sealing ring is provided on the vibration plate, and the bottom of the sealing ring is connected to the mounting bracket.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the sealing ring seals the gap between the vibrating plate and the mounting frame, preventing materials from falling through the gap between the vibrating plate and the mounting frame during use.
[0011] In a preferred embodiment, the output end of the heating mechanism is fixedly connected to the connecting pipe, and the other end of the heating mechanism is fixedly connected to the input end of the air outlet hood.
[0012] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the heating mechanism, external air is drawn into the interior and heated, and the heated air is discharged through the connecting pipe and introduced into the air outlet hood.
[0013] In a preferred embodiment, a filter cover is provided on one side of the heating mechanism through the base box, and the diameter of the filter cover is adapted to the diameter of the input end of the heating mechanism.
[0014] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the filter cover, the space entering the heating mechanism is filtered, preventing air containing impurities from entering the heating mechanism and causing contamination to the material during subsequent material drying and processing.
[0015] In a preferred embodiment, mounting support plates are provided on both sides of the base box, and mounting holes are provided on the mounting support plates.
[0016] The beneficial effects of adopting the above-mentioned further solution are: under the action of the mounting support plate, the contact surface between the base box and the ground is increased, and further, under the action of the mounting holes, the base box is bolted to the ground by bolts.
[0017] In a preferred embodiment, a through hole is provided on the base plate above the heating mechanism, and the diameter of the through hole decreases sequentially from the side away from the connecting shaft to the side closer to the connecting shaft.
[0018] The beneficial effects of adopting the above-mentioned further solution are: under the action of the through holes, the air discharged from the air outlet hood is guided to the inside of the protective cover, and the diameter of the through holes decreases in sequence to ensure that the gas enters the fluidized bed uniformly and stably, making the material fluidization more uniform.
[0019] In a preferred embodiment, the blades are on the same horizontal line and the distance between two adjacent blades is equal.
[0020] The beneficial effects of adopting the above-mentioned further solution are: under the action of the blades, when the first drive motor drives the rotating shaft to rotate, it will drive the blades to rotate inside the protective cover. The blades will generate air vortices inside the protective cover, which will accelerate the circulation of hot air and improve work efficiency during the heating process of the material.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] 1. In this utility model, firstly, by using progressively decreasing through holes, gas is ensured to enter the fluidized bed uniformly and stably, making the material fluidization more uniform. Secondly, by turning on the first drive motor to start the rotating shaft, the blades rotate inside the protective cover to generate air vortices. Under the action of the air vortices, the flow of hot air inside the protective cover is accelerated, improving work efficiency. Furthermore, the vortices generated by the blades can also accelerate the displacement speed of the dried material inside the protective cover.
[0023] 2. In this utility model, under the action of the second drive motor, the connecting shaft is driven to rotate, so that the connecting shaft drives the eccentric roller to contact the bottom of the vibrating plate in sequence, thereby causing the vibrating plate to vibrate up and down. When the vibrating plate vibrates up and down, it can not only drive the material to bounce, but also disperse the agglomerated material under the action of vibration, thereby improving the practicality of the device.

[0032] 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.
[0033] like Figure 1-5 As shown, this utility model provides a technical solution: a fluidized bed for drying acrylamide copolymers, comprising:
[0034] The conveying assembly 1 consists of a protective cover 11 and two upright plates 13. The upright plates 13 are respectively disposed at both ends of the protective cover 11. A base plate 14 is disposed at the bottom of the protective cover 11 and the upright plates 13. A mounting bracket 141 is disposed inside the base plate 14 of the protective cover 11. A vibrating plate 15 is disposed above the mounting bracket 141. A mounting plate 143 is disposed on the base plate 14 below the vibrating plate 15. There are two mounting plates 143, and the two mounting plates 143 are rotatably connected. A shaft 144 is provided, on which a second drive motor 146 is provided on one of the mounting plates 143. The output end of the second drive motor 146 is connected to the connecting shaft 144. An eccentric roller 145 is provided on the connecting shaft 144. The eccentric roller 145 contacts the bottom of the vibrating plate 15. A rotating shaft 132 is rotatably connected between the two vertical plates 13. A blade 133 is provided on the rotating shaft 132. A first drive motor 131 is provided on one of the vertical plates 13. The output end of the first drive motor 131 is connected to the rotating shaft 132.
[0035] Heating assembly 2 includes a base box 21 disposed at the bottom of base plate 14. A heating mechanism 23 is fixedly connected inside the base box 21. An air outlet hood 25 is disposed above the heating mechanism 23 inside the base box 21. A connecting pipe 24 is disposed between the heating mechanism 23 and the air outlet hood 25. The output end of the heating mechanism 23 is fixedly connected to the connecting pipe 24, and the other end of the heating mechanism 23 is fixedly connected to the input end of the air outlet hood 25. A through hole 142 is opened on the base plate 14 above the heating mechanism 23. The diameter of the through hole 142 extends from the side away from the connecting shaft 144 to the side closer to the connecting shaft 144. The blades 133 are positioned on the same horizontal line, with equal spacing between adjacent blades 133. First, the gas enters the fluidized bed uniformly and stably through the progressively decreasing through holes 142, making the material fluidization more uniform. Second, the first drive motor 131 is turned on to rotate the shaft 132, causing the blades 133 to rotate inside the protective cover 11 and generate air vortices. Under the action of the air vortices, the flow of hot air inside the protective cover 11 is accelerated, improving working efficiency. Furthermore, the vortices generated by the blades 133 can also accelerate the displacement speed of the dried material inside the protective cover 11.
[0036] Furthermore, such as Figures 2-5 As shown: A sealing ring 151 is provided on the vibrating plate 15. The bottom of the sealing ring 151 is connected to the mounting frame 141. Under the action of the second drive motor 146, the connecting shaft 144 is driven to rotate, so that the connecting shaft 144 drives the eccentric roller 145 to contact the bottom of the vibrating plate 15 in turn, thereby causing the vibrating plate 15 to vibrate up and down. When the vibrating plate 15 vibrates up and down, it can not only cause the material to bounce and move, but also disperse the agglomerated material under the action of vibration, thereby improving the practicality of the device.
[0037] The above solutions also have the problem of the heating mechanism 23 drawing in impurities and contaminating the material, such as... Figure 5 As shown: In this scheme, a filter cover 231 is provided on one side of the heating mechanism 23 that penetrates the base box 21. The diameter of the filter cover 231 is adapted to the diameter of the input end of the heating mechanism 23. Under the action of the filter cover 231, the space entering the heating mechanism 23 is filtered to prevent air with impurities from entering the interior of the heating mechanism 23, which would cause subsequent material drying and processing and contaminate the material.
[0038] The above solutions also suffer from the problem of displacement caused by device vibration, such as... Figure 5 As shown: In this solution, mounting support plates 22 are provided on both sides of the base box 21. Mounting support plates 22 are provided with mounting holes 221. Under the action of the mounting support plates 22, the contact surface between the base box 21 and the ground is increased. Furthermore, under the action of the mounting holes 221, the base box 21 is bolted to the ground.
[0039] like Figure 1-5 As shown, the base box 21 is bolted to the ground through the mounting hole 221. After fixing, the feeding mechanism is connected to the top of the protective cover 11, and the discharge mechanism is connected to the connecting plate 121. After installation, the feeding mechanism is turned on and the material is put into the protective cover 11. Under the action of the second drive motor 146, the eccentric roller 145 is driven to contact the bottom of the vibrating plate 15 in sequence, so that the vibrating plate 15 vibrates up and down, causing the material to bounce and move. At this time, under the action of the heating mechanism 23, the external air is drawn in and heated, and the heated air is guided to the air outlet hood 25 through the connecting pipe 24. At this time, under the action of the through hole 142, the hot air is introduced into the protective cover 11 to heat and dry the material. At this time, under the action of the vertical plate 13, the blade 133 is driven to rotate in the protective cover 11, accelerating the air circulation and generating vortex to assist in pushing the material to move until the material moves to the bottom of the storage pipe 12 and is discharged through the storage pipe 12.
[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
