Description

Technical Field

[0001] This utility model belongs to the technical field of ion exchange resin production, and in particular relates to a drying device for ion exchange resin production. Background Technology

[0002] Ion exchange resins are a class of high-molecular-weight polymers with a network structure containing functional groups. They can selectively adsorb or release specific ions in aqueous solutions through ion exchange and are widely used in water treatment, chemical separation, and food processing. Their performance depends on the degree of crosslinking, the type of functional groups, and the particle morphology of the resin. In the production process of ion exchange resins, a fluidized bed dryer is one of the key pieces of equipment. It uses hot air (or other heat medium) to be introduced from the bottom, allowing the resin particles in a fluidized state to come into full contact with the heat medium, thereby quickly removing moisture or solvent from the resin. This drying method has advantages such as high drying efficiency, uniform heating of resin particles, and resistance to agglomeration, effectively ensuring the quality and performance of ion exchange resins.

[0003] However, in actual use, it still has the following drawbacks: In the drying of ion exchange resins, if the wet ion exchange resin contains a lot of lumps or agglomerates, it is difficult to fluidize uniformly in the fluidized bed, which easily forms a "dead bed" (local material accumulation without flow), resulting in uneven drying. Some materials may deteriorate due to excessive heating, while others may not meet the drying requirements. For paste-like resins with high water content, direct entry into the fluidized bed can easily cause them to stick to the distribution plate or the wall of the container. At the same time, the energy consumption is relatively high. Fluidized bed drying relies on hot airflow to fluidize the material. In order to maintain stable fluidization, a large amount of hot air needs to be continuously introduced, and the air utilization rate is low (some heat is directly discharged with the exhaust gas). Ion exchange resins are usually granular with low bulk density, and the air velocity required for fluidization is high, which further increases the power consumption of the fan and the heat loss. Especially in large-scale production, the energy consumption problem is more prominent. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for the production of ion exchange resins. By setting up a dehydration component, it solves the problems of high energy consumption, unsatisfactory drying effect, and uneven heating and drying of the resin due to its tendency to clump, which affects the quality of the final product.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a drying device for the production of ion exchange resin, including a fluidized bed dryer, a dispersing component and a dehydration component connected in sequence. The fluidized bed dryer includes a fluidized bed main unit, an air supply component is provided on one side of the fluidized bed main unit, a separation and dust removal component is provided on the upper surface of the fluidized bed main unit, and a vibration motor is fixed on both sides of the fluidized bed main unit.

[0007] The dewatering assembly includes a support frame, on which an outer cylinder is vertically fixed. An inner cylinder is rotatably connected to the inner cavity of the outer cylinder. Several water passage holes are opened on the circumferential side of the inner cylinder. The top of the inner cylinder protrudes from the outer cylinder and is rotatably connected to a feed hopper. The bottom of the inner cylinder protrudes from the outer cylinder as a discharge port.

[0008] A bevel gear 1 is fixed to the outer periphery of the top of the inner cylinder, a motor 1 is fixed to the top of the outer cylinder 1, and a bevel gear 2 that meshes with the bevel gear 1 is fixed to the power shaft of the motor 1.

[0009] Furthermore, a water outlet pipe is also connected through the outer periphery of the outer cylinder, and a water valve is installed on the water outlet pipe.

[0010] Furthermore, the dehydration assembly also includes a housing fixed to the top of the outer cylinder, and the motor, bevel gear 2, and bevel gear 1 are all located inside the housing.

[0011] Furthermore, a numerically controlled valve is installed at the discharge port.

[0012] Furthermore, the dispersing component includes an outer cylinder two fixed on a support frame, with the discharge port connected to the top of the outer cylinder two at one end away from the inner cylinder. A spiral blade is rotatably connected to the inner cavity of the outer cylinder two. A motor two is fixed at the bottom of the outer cylinder two, and a reduction gearbox is provided at the output end of the motor two. The output shaft of the reduction gearbox extends into the inner cavity of the outer cylinder two and is fixedly connected to the central shaft of the spiral blade. An inclined connecting pipe is fixed through the bottom of the outer cylinder two, and the end of the connecting pipe away from the outer cylinder two is connected to the inlet end of the fluidized bed host.

[0013] Furthermore, the connecting pipe has multiple flow chambers inside, and the inner diameter of each flow chamber gradually increases from one side of the outer cylinder to the side of the fluidized bed host. The bottom end faces of both the inner cylinder and the outer cylinder are inclined.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through its dehydration component, allows resin to be placed into the inner cylinder of the dehydration component via the feed hopper during use. The motor is then started to drive the inner cylinder to rotate at high speed. Under centrifugal force, the resin adheres tightly to the inner wall of the inner cylinder, while water is flung out through the water passage to the inner cavity of the outer cylinder, achieving initial dehydration. The dehydration component reduces the initial water content of the resin through centrifugal dehydration, solving the problems of high energy consumption, unsatisfactory drying effects, and uneven heating and drying of the resin due to its inherent tendency to clump, which negatively impacts the quality of the final product.

[0016] 2. This utility model, through the setting of a dispersing component, allows the dehydrated resin to enter the outer cylinder two. The motor two is started, and its output end, after adjusting the speed through a reduction gearbox, drives the spiral blade to rotate. During the rotation of the spiral blade, the resin that may clump is stirred, achieving thorough dispersal. The dispersed resin, pushed by the spiral blade and guided by the inclined bottom end of the outer cylinder two, enters the connecting pipe. As the inner diameter of the flow cavity of the connecting pipe gradually increases, the resin is further dispersed during the flow process, avoiding secondary clumping. This solves the problem that directly placing the resin into the fluidized bed dryer may result in uneven dispersion, adhesion, and uneven drying, affecting the quality of the finished product.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-5 As shown, this utility model is a drying device for the production of ion exchange resin, including a fluidized bed dryer 1, a dispersing component 3 and a dehydration component 2 connected in sequence. Each component works together to complete the dehydration, dispersing and drying of the ion exchange resin. The fluidized bed dryer 1 includes a fluidized bed host 11, an air supply component 12 is provided on one side of the fluidized bed host 11, a separation and dust removal component 13 is provided on the upper surface of the fluidized bed host 11, and a vibration motor 14 is fixed on both sides of the fluidized bed host 11.

[0028] The fluidized bed dryer 1 includes a fluidized bed main unit 11, with an air supply component 12 on one side (for providing hot drying air), a separation and dust removal component 13 on the upper surface (for separating dust generated during the drying process), and vibration motors 14 fixed on both sides (to make resin particles uniformly fluidized in the fluidized bed through vibration).

[0029] The dewatering assembly 2 includes a support frame 21, on which an outer cylinder 22 is vertically fixed. An inner cylinder 23 is rotatably connected to the inner cavity of the outer cylinder 22. Several water passage holes 231 are opened on the circumferential side of the inner cylinder 23. The top of the inner cylinder 23 protrudes from the outer cylinder 22 and is rotatably connected to a feed hopper 24. The bottom of the inner cylinder 23 protrudes from the outer cylinder 22 and is a discharge port 25. A bevel gear 26 is fixed to the outer circumferential side of the top of the inner cylinder 23. A motor 28 is fixed to the top of the outer cylinder 22. A bevel gear 27 that meshes with the bevel gear 26 is fixed to the power shaft of the motor 28.

[0030] The dehydration component 2 operates primarily on the principle of centrifugal force. Power is generated by motor 28, and transmitted through bevel gears 26 and 27, causing the inner cylinder 23 to rotate at high speed. Water is ejected from the water inlet 231 by centrifugal force, while the ion exchange resin remains in the inner cylinder 23, thus achieving initial dehydration.

[0031] Furthermore, an outlet pipe 221 is also connected to the outer periphery of the outer cylinder 22. A water valve is installed on the outlet pipe 221. The outlet pipe 221 is used to discharge the water in the ion exchange resin thrown out by the dehydration component 2. The water valve is used to control the opening and closing of the outlet pipe 221.

[0032] Furthermore, the dehydration assembly 2 also includes a housing 29 fixed to the top of the outer cylinder 22. The motor 28, bevel gear 27 and bevel gear 26 are all located inside the housing 29. The housing 29 is used to protect easily damaged components such as the motor 28, bevel gear 26 and bevel gear 27.

[0033] Furthermore, a numerical control valve 251 is provided on the discharge port 25, which is also an electric gate valve, to facilitate the control of the opening and closing of the discharge port 25.

[0034] Furthermore, the dispersing component 3 includes an outer cylinder 31 fixed on the support frame 21. The discharge port 25 is connected to the top of the outer cylinder 31 at one end away from the inner cylinder 23. A spiral blade 32 is rotatably connected to the inner cavity of the outer cylinder 31. A motor 33 is fixed at the bottom of the outer cylinder 31. A reduction gearbox 35 is provided at the output end of the motor 33. The output shaft of the reduction gearbox 35 extends into the inner cavity of the outer cylinder 31 and is fixedly connected to the central shaft of the spiral blade 32. An inclined connecting pipe 34 is fixedly connected to the bottom of the outer cylinder 31. The end of the connecting pipe 34 away from the outer cylinder 31 is connected to the inlet end of the fluidized bed host 11. The dispersing component 3 mainly uses the spiral blade 32 to slowly and more disperse the movement of the ion exchange resin, preventing the ion exchange resin from accumulating and causing uneven heating due to excessive concentration during drying.

[0035] Furthermore, the connecting pipe 34 has multiple flow chambers 341 inside, and the inner diameter of each flow chamber 341 gradually increases from the outer cylinder 21 side to the fluidized bed host 11 side. The bottom end faces of the inner cylinder 23 and the outer cylinder 21 are both inclined. The flow chambers 341 can deliver the ion exchange resin to the fluidized bed host 11 in a more dispersed manner, thereby improving the drying efficiency and drying quality. The bottom cross-sections of the inner cylinder 23 and the outer cylinder 21 are roughly conical, which allows the ion exchange resin to flow out better and without residue.

[0036] The specific working principle of this utility model is as follows: When using this device, the ion exchange resin to be dried is placed into the inner cylinder 23 of the dehydration component 2 through the feed hopper 24. The motor 28 is started, and its power shaft drives the bevel gear 27 to rotate. Through the meshing transmission with the bevel gear 26, the inner cylinder 23 is driven to rotate at high speed in the outer cylinder 22. Under the action of centrifugal force, the resin adheres tightly to the inner wall of the inner cylinder 23. The water is thrown out to the inner cavity of the outer cylinder 22 through the water passage 231. The accumulated water can be discharged through the water outlet 221 (open the water valve). The dehydrated resin, under its own gravity and the guidance of the inclined bottom of the inner cylinder 23, enters the dispersing component 3 through the discharge port 25 (the flow rate is controlled by the CNC valve 251).

[0037] After the dehydrated resin enters the outer cylinder 31, the motor 33 is started. Its output end adjusts the speed through the reduction gearbox 35 and drives the spiral blade 32 to rotate. During the rotation, the spiral blade 32 stirs the resin that may clump, achieving full dispersion. The dispersed resin enters the connecting pipe 34 under the push of the spiral blade 32 and the guidance of the inclined bottom of the outer cylinder 31. As the inner diameter of the flow cavity 341 of the connecting pipe 34 gradually increases, the resin is further dispersed during the flow process, avoiding secondary clumping.

[0038] The dispersed resin enters the fluidized bed host 11 through the connecting pipe 34. The vibration motor 14 and the air supply component 12 are started. The vibration motor 14 causes the resin particles in the fluidized bed host 11 to vibrate and fluidize. The air supply component 12 introduces hot air, which comes into full contact with the fluidized resin to achieve moisture evaporation. The dust generated during the drying process is collected and treated by the separation and dust removal component 13. The dried resin completes the production process.

[0039] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
