Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical wastewater treatment technology, specifically to an ion exchange bed with the function of shortening regeneration time. Background Technology
[0002] Acid-cation bed is short for mixed ion exchange column. Currently, the demineralized water system in thermal power plants and this process both adopt a design of pre-filter plus cation bed, anion bed and mixed bed. The regeneration method of cation-cation bed is usually divided into two types: regeneration based on acid-base contact time and acid-base quantitative regeneration.
[0003] In the existing ion exchange bed with the function of shortening regeneration time, the purity of the regenerant has a great impact on the degree of regeneration and the quality of the effluent. This results in the regenerant containing a large number of counterions or other impurity ions, which leads to a decrease in the purity of the mixture, a reduction in the degree of regeneration, and a prolongation of the regeneration time. At the same time, the pipeline is not equipped with a heating mechanism during the transportation process, which makes the diffusion of ions in the regenerant liquid slow and reduces the quality of the regeneration reaction. Utility Model Content

It has the advantages of ensuring the purity of the regeneration solution, shortening the time, and increasing the temperature of the regeneration solution, thus solving the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: an yin-yang bed with a function to shorten regeneration time, including a yang bed body. A second motor is fixedly installed on the top of the yang bed body. A cam is fixedly mounted on the power output shaft of the second motor.

A third motor is fixedly installed on the inner wall of the protective shell. A stirring rod is fixedly mounted on the power output shaft of the third motor. An installation rod is fixedly installed on the outer wall of the stirring rod. A sealing plate is slidably connected to the inner wall of the installation rod.

A pipe is fixedly installed at the bottom of the male bed, and a heating rod is fixedly installed on the pipe. A first motor is fixedly installed on the heating rod, and a gear is fixedly assembled on the power output shaft of the first motor. An adjusting plate meshes with the outer wall of the gear. A fixing plate is fixedly connected to the outer wall of the pipe, and a female bed is fixedly connected to the other end of the pipe. A sealing ring is fixedly installed at the top of the male bed, and a controller is fixedly connected to the outer wall of the male bed. A decarbonizer body is fixedly installed on the outer wall of the pipe, and a protective rod is fixedly installed at the top of the male bed.
[0006] As a preferred technical solution of this utility model: the controller and the second motor are electrically connected; the outer edge of the cam has a thicker diameter and the other part has a thinner diameter, and the thicker outer edge is rotatably connected to the rotating plate; the locking block is engaged with the locking groove; and the outer wall of the scraper is in contact with the inner wall of the male bed.
[0007] As a preferred technical solution of this utility model: the controller is electrically connected to the third motor, and an inlet is fixedly installed on the outer wall of the male bed.
[0008] As a preferred technical solution of this utility model: the controller and the pump body are electrically connected, and the pipeline is connected through the inner wall of the pump body.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This yin-yang bed with the function of shortening regeneration time is controlled by a controller. The third motor drives the stirring rod to rotate, which in turn stirs the regenerated liquid inside the bed. The second motor drives the cam to rotate, which in turn drives the round rod to move up and down on the inner wall of the bed via a rotating plate. This causes the mounting rod to drive the scraper to thoroughly scrape and stir the inner wall of the bed, preventing the regenerated liquid from adhering to the inner wall of the bed. The locking block engages with the locking slot. When the external force is applied to the locking block, the locking block resists the spring and disengages from the locking slot. This allows the scraper to disengage from the mounting rod via the sealing plate, enabling disassembly and assembly. This facilitates replacement by personnel according to usage conditions.
[0013] 2. This anion and cation bed with the function of shortening regeneration time uses a temperature sensor to monitor the inner wall temperature of the pipeline in real time and transmits the data to the controller. The controller then controls the heating rod to heat the pipeline, and the heat is conducted to the inner wall liquid through the pipeline, thereby heating and increasing the ion diffusion rate of the regenerated liquid, thus shortening the regeneration time. The first motor drives the gear to rotate, and the gear drives the outer wall of the adjusting plate and the fixed plate to be misaligned, so that the included angle between the fixed plate and the adjusting plate changes, thereby regulating the regenerated liquid flow rate. The liquid is guided through the pipeline to the decarbonizer body, where carbon dioxide is extracted and decomposed. The pump body then transports the liquid to the anion bed body.

[0020] 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.
[0021] Please see Figure 1 - Figure 5A yin-yang bed with the function of shortening regeneration time includes a yang bed body 1. A second motor 12 is fixedly installed on the top of the yang bed body 1. A cam 14 is fixedly mounted on the power output shaft of the second motor 12. A rotating plate 15 is rotatably connected to the outer wall of the cam 14. A round rod 16 is rotatably connected to the rotating plate 15. A protective shell 23 is fixedly installed on the round rod 16. A third motor 22 is fixedly installed on the inner wall of the protective shell 23. A stirring rod 24 is fixedly mounted on the power output shaft of the third motor 22. An installation rod 27 is fixedly installed on the outer wall of the stirring rod 24. A sealing plate 29 is slidably connected to the inner wall of the installation rod 27. A scraper 25 is fixedly connected to the sealing plate 29. A spring 30 is fixedly connected to 29. A locking block 26 is fixedly installed at one end of the spring 30. A pipe 2 is fixedly installed at the bottom of the male bed 1. A heating rod 3 is fixedly installed on the pipe 2. A first motor 5 is fixedly installed on the heating rod 3. A gear 6 is fixedly assembled on the power output shaft of the first motor 5. An adjusting plate 7 meshes with the outer wall of the gear 6. A fixing plate 20 is fixedly connected to the outer wall of the pipe 2. A female bed 9 is fixedly connected to the other end of the pipe 2. A sealing ring 17 is fixedly installed on the top of the male bed 1. A controller 4 is fixedly connected to the outer wall of the male bed 1. A decarbonizer body 8 is fixedly installed on the outer wall of the pipe 2. A protective rod 13 is fixedly installed on the top of the male bed 1.
[0022] In the above structure, by installing the sealing ring 17, the round rod 16 drives the stirring rod 24 to move up and down and stir on the inner wall of the anode bed 1, so as to prevent the regenerated liquid from overflowing through the top of the anode bed 1 due to fluctuations, thereby improving the sealing performance of the anode bed 1.
[0023] In a preferred embodiment: the controller 4 is electrically connected to the second motor 12, the outer edge of the cam 14 has a thicker diameter and the other part has a thinner diameter, and the thicker outer edge is rotatably connected to the rotating plate 15, the locking block 26 is engaged with the locking groove 28, and the outer wall of the scraper 25 is in contact with the inner wall of the male bed body 1.
[0024] In the above structure, the controller 4 uses the second motor 12 to drive the cam 14 to rotate, so that the cam 14 drives the round rod 16 to move up and down on the inner wall of the anode bed 1 via the rotating plate 15. This causes the mounting rod 27 to drive the scraper 25 to thoroughly scrape and stir the inner wall of the anode bed 1, preventing the regenerated liquid from adhering to the inner wall of the anode bed 1. The locking block 26 is engaged with the locking groove 28. When the external force presses the locking block 26, the locking block 26 abuts against the spring 30, and the locking block 26 disengages from the locking groove 28. This causes the scraper 25 to disengage from the mounting rod 27 via the sealing plate 29, making it easy for personnel to replace the cleaning equipment according to the usage.
[0025] In a preferred embodiment: the controller 4 is electrically connected to the third motor 22, and the inlet 11 is fixedly installed on the outer wall of the male bed body 1.
[0026] In the above structure, the raw material enters the inner wall of the anode bed 1 through the inlet 11 and is decomposed by the anode bed 1. By controlling the controller 4, the third motor 22 drives the stirring rod 24 to rotate, so that the stirring rod 24 stirs the regenerated liquid inside the anode bed 1. The round rod 16 drives the stirring rod 24 to move up and down and stir the inner wall to avoid sedimentation of the regenerated liquid. The stirring rod 24 rises by buoyancy, so that the stirring rod 24 can fully decompose the regenerated liquid.
[0027] In a preferred embodiment: the controller 4 is electrically connected to the pump body 10, and the pipe 2 is through-connected through the inner wall of the pump body 10.
[0028] In the above structure, by controlling the controller 4, the pump body 10 adsorbs the liquid on the inner wall of the cation bed 1 to the inner wall of the pipe 2, and guides it to the decarbonizer body 8 through the pipe 2. Carbon dioxide is extracted and decomposed in the decarbonizer body 8, and the pump body 10 is used to transfer the liquid to the anion bed 9.
[0029] In a preferred embodiment: the controller 4 is electrically connected to the temperature sensor 21, the outer wall of the pipe 2 is provided with a semi-arc groove 18, and a heating rod 3 is fixedly installed on the inner wall of the semi-arc groove 18.
[0030] In the above structure, the temperature sensor 21 monitors the inner wall temperature of the pipe 2 in real time by controlling the controller 4, and transmits the data to the controller 4, so that the controller 4 controls the heating rod 3 to heat the pipe 2, and uses the pipe 2 to conduct heat to the inner wall liquid, thereby achieving heating, improving the ion diffusion rate of the regenerated liquid, and shortening the regeneration time.
[0031] In a preferred embodiment: the controller 4 is electrically connected to the first motor 5, the inner wall of the pipe 2 is fixedly installed with a fixing plate 20, and the support rod 19 is rotatably connected to the fixing plate 20.
[0032] In the above structure, by controlling the controller 4, the first motor 5 drives the gear 6 to rotate, and the gear 6 drives the adjusting plate 7 to be misaligned with the outer wall of the fixed plate 20, so that the included angle between the fixed plate 20 and the adjusting plate 7 changes, thereby adjusting the regeneration fluid flow rate.
[0033] Working principle: Raw materials enter the inner wall of the anode bed 1 through inlet 11 and are decomposed by the anode bed 1. The controller 4 uses a third motor 22 to drive the stirring rod 24 to rotate, causing the stirring rod 24 to agitate the regenerated liquid inside the anode bed 1. The controller 4 also uses a second motor 12 to drive the cam 14 to rotate, causing the cam 14 to drive the round rod 16 to move up and down on the inner wall of the anode bed 1 via the rotating plate 15. This causes the mounting rod 27 to drive the scraper 25 to thoroughly scrape and agitate the inner wall of the anode bed 1, preventing the regenerated liquid from adhering to the inner wall. The round rod 16 drives the stirring rod 24 to move up and down on the inner wall to agitate, preventing the regenerated liquid from settling. The buoyancy of the stirring rod 24 ensures thorough decomposition of the regenerated liquid. A locking block 26 engages with a locking groove 28. When external force presses on the locking block 26, it resists the spring 30, disengaging the locking block 26 from the locking groove 28. The scraper 25, through the sealing plate 29, causes the locking block 26 to disengage from the mounting rod 27, allowing the scraper 25 to be disassembled and installed, facilitating personnel to replace the cleaning equipment according to usage. The pump body 10 adsorbs the liquid on the inner wall of the cation bed 1 onto the inner wall of the pipe 2. The temperature sensor 21 monitors the temperature of the inner wall of the pipe 2 in real time and transmits the data to the controller 4, which then controls the heating rod 3 to heat the pipe 2. The heat is then conducted to the inner wall liquid through the pipe 2, thereby achieving heating, increasing the ion diffusion rate of the regenerated liquid, and shortening the regeneration time. The first motor 5 drives the gear 6 to rotate, and the gear 6 causes the adjusting plate 7 to be misaligned with the outer wall of the fixed plate 20, changing the angle between the fixed plate 20 and the adjusting plate 7, thereby adjusting the flow rate of the regenerated liquid. The liquid is then guided through the pipe 2 to the decarbonizer 8, where carbon dioxide is extracted and decomposed. The pump body 10 then transports the liquid to the anion bed 9.
