[0002] Fluidized bed is a chemical unit operation equipment. It suspends solid particles under the action of gas or liquid to form a fluid-like state, thereby achieving efficient mass transfer, heat transfer and chemical reactions. In the fluidized bed, solid particles are violently mixed and moved under the impetus of the fluid. This state is similar to the boiling of liquid. Therefore, the fluidized bed has good heat and mass transfer performance. Fluidized bed is suitable for many fields. For example, solid-liquid separation fluidized bed is used for solid-liquid separation of circulating water in thermal power plants.

In addition, in order to achieve the purpose of rapid mixing of the reagents and the treatment liquid, there will also be a drug distribution structure in the dosing device, so that the drug can be added to the treatment liquid in small amounts and multiple times to ensure that the drug can be quickly mixed with the treatment liquid. However, different reagents have different forms, so it is necessary to use a variety of dosing devices to divide and add different reagents, which will increase multiple power equipment, which will not only greatly increase the cost, but also increase the failure rate.

[0047] like Figure 1 - Fig.10As shown, the embodiment of the present invention provides a solid-liquid separation fluidized bed for a circulating water system of a thermal power plant, comprising a fluidized bed body 1, a connection block 5 is fixedly connected to the outer surface of the fluidized bed body 1, and a medicine delivery mechanism 2 and a medicine dispensing mechanism 3 are respectively arranged on the outer side of the fluidized bed body 1;

[0048] The medicine delivery mechanism 2 is arranged above the fluidized bed body 1, and the medicine delivery mechanism 2 includes a circular cylinder 202. The outer surface of the circular cylinder 202 is fixedly connected to the inner wall of the connecting block 5, and the upper surface of the circular cylinder 202 and the upper surface of the connecting block 5 are jointly fixedly connected with a gear metering pump 201. The input end of the gear metering pump 201 is fixedly connected to a first extraction pipe 208, and the bottom end of the first extraction pipe 208 passes through the interior of the circular cylinder 202.

[0049] The outer surface of the first extraction pipe 208 is fixedly connected to a first solenoid valve 207, the top of the circular cylinder 202 is fixedly connected to an injection pipe 206, the outer surface of the injection pipe 206 is threadedly connected to a threaded cap 205, the output end of the gear metering pump 201 is fixedly connected to a first discharge pipe 209, the bottom end of the first discharge pipe 209 penetrates the fluidized bed body 1 and extends to the inside of the fluidized bed body 1, the outer surface of the first discharge pipe 209 is fixedly connected to a second solenoid valve 211, the outer surface of the first discharge pipe 209 is fixedly connected to a second discharge pipe 210, and the second The outer surface of the discharge pipe 210 is fixedly connected to a third solenoid valve 212, the bottom end of the fluidized bed body 1 is fixedly connected to a circular cover 203, the top of the circular cover 203 is fixedly connected to three delivery pipes 214, the outer surface of each delivery pipe 214 is threadedly connected to a threaded cover 215, the inner wall of the circular cover 203 is fixedly connected to two partitions 216, the inner wall of the circular cover 203 is fixedly connected to three guide pipes 217, the inner wall of the circular cover 203 is fixedly connected to a rectangular block 204, the inner wall of the rectangular block 204 is fixedly connected to the outer surfaces of the three guide pipes 217 The inner wall of the rectangular block 204 is fixedly connected with three square plates 213, the inner wall of each square plate 213 is fixedly connected with the outer surface of the second discharge pipe 210, the back of each square plate 213 is fixedly connected with a return spring 221, the end of each return spring 221 away from the square plate 213 is fixedly connected with a connecting plate 220, the outer surface of each connecting plate 220 is fixedly connected with a moving cylinder 219, the top of each moving cylinder 219 is in contact with the bottom end of the guide pipe 217, and the outer surface of each moving cylinder 219 is fixedly connected with a baffle 218, the upper surface of each baffle 218 contacts the inner top wall of the rectangular block 204, the inner wall of the fluidized bed body 1 is fixedly connected with a fixed plate 224, the upper surface of the fixed plate 224 is fixedly connected to the bottom surface of the rectangular block 204, the upper surfaces of the fixed plate 224 are respectively in contact with the bottom ends of three moving cylinders 219, the inner wall of the fixed plate 224 is fixedly connected with a guide block 222, the upper surface of the guide block 222 and the upper surface of the fixed plate 224 are jointly provided with a circular opening 223, and the inner wall of the fixed plate 224 is fixedly connected to the outer surface of the first discharge pipe 209.

[0050] like Figure 1 , Figure 3 , Figure 4As shown, a force-bearing plate 18 is fixedly connected to the upper surface of the connecting block 5, and the inner wall of the force-bearing plate 18 is fixedly connected to the outer surface of the first discharge pipe 209 and the outer surface of the second discharge pipe 210 respectively. By providing the force-bearing plate 18, the force-bearing plate 18 can be used to provide a stable supporting force for the first discharge pipe 209 and the second discharge pipe 210, thereby ensuring that the first discharge pipe 209 and the second discharge pipe 210 will not collapse due to gravity when transporting substances.

[0051] The inner wall of the connecting block 5 is fixedly connected with a placement frame 16, and the inner wall of the placement frame 16 is fixedly connected with three carrier plates 17. The upper surface of the placement frame 16 is fixedly connected to the bottom surface of the force-bearing plate 18. By providing the placement frame 16 and the carrier plates 17, a space for placing tools can be provided through the placement frame 16, and the carrier plates 17 can provide classification space for different tools.

[0052] A rectangular plate 15 is clamped inside the placement frame 16, and the inner wall of the connecting block 5 is rotatably connected to two short shafts 13. The left end of each short shaft 13 is fixedly connected to a limiting plate 14, and the right side of each limiting plate 14 is in contact with the left side of the rectangular plate 15 and the left side of the connecting block 5. By providing the rectangular plate 15, the short shaft 13 and the limiting plate 14, the position of the limiting plate 14 can be adjusted using the short shaft 13, thereby determining whether the limiting plate 14 provides a limiting effect on the rectangular plate 15.

[0053] When in use, firstly, the threaded cap 205 is screwed to leak out the injection tube 206 below the threaded cap 205, and then the liquid medicine is added to the circular cylinder 202 through the injection tube 206. When the liquid medicine needs to be administered, the gear metering pump 201 is controlled to operate, and the first solenoid valve 207 and the second solenoid valve 211 are controlled to open, and the third solenoid valve 212 and the fourth solenoid valve 405 are closed. Then, the gear metering pump 201 and the first extraction tube 208 are used to extract the liquid medicine inside the circular cylinder 202. At this time, since the first solenoid valve 207 and the second solenoid valve 211 are in the open state, the liquid medicine can be guided to the corresponding rotating cylinder 3 under the joint action of the first extraction tube 208 and the first discharge tube 209. 05, the addition of liquid medicine is completed at this time. When powder medicine needs to be added, the threaded cover 215 is still screwed, and the powder medicine and granular medicine are added to the inside of the circular cover 203 through the delivery tube 214. There is a partition 216 inside the circular cover 203, which can disperse the three different medicines in three independent spaces. When one of the medicines needs to be added, the corresponding third solenoid valve 212 and fourth solenoid valve 405 are controlled to open, and then the first solenoid valve 207 and the second solenoid valve 211 are controlled to close. It should be understood here that the three third solenoid valves 212 control the addition of three different medicines. Therefore, when three different medicines are put in sequence, it is only necessary to open the three third solenoid valves in sequence. 212, when the third solenoid valve 212 is opened, the gas extracted from the second extraction pipe 404 will be transferred to the inside of the rectangular block 204. At this time, under the action of the gas, the moving cylinder 219 and the connecting plate 220 inside the rectangular block 204 will be squeezed out of the inside of the rectangular block 204 by the gas. At this time, the powdered medicine or granular medicine inside the moving cylinder 219 will be sprinkled into the guide block 222. The guide block 222 has a slope with a large angle, and the center is the circular opening 223. Therefore, it can be ensured that when the medicine is put in, it will not accumulate in a corner of the guide block 222, but all the medicines are guided to the center of the circular opening 223 by the slope, and the medicines are poured into the circular opening 223 opened in the guide block 222. It is guided again to the inside of the corresponding rotating cylinder 305. It should be noted here that the outer surface of the moving cylinder 219 is connected to the baffle 218, so when the moving cylinder 219 moves, the baffle 218 will move along with it. When the moving cylinder 219 moves to the top of the guide block 222, the baffle 218 will be just below the guide tube 217 to prevent the medicine inside the guide tube 217 from spilling downward. Repeat the above operation and add the three medicines in turn. In this way, the powdered medicine and granular medicine are added, thereby effectively avoiding the need to use corresponding dosing equipment due to the different forms of the medicines when the device is in use. Not only does the failure rate increase significantly, but there is also a problem of high investment cost.

[0054] like Fig. 9 - Fig.10 As shown, the medicine dispensing mechanism 3 is arranged inside the fluidized bed body 1, and the medicine dispensing mechanism 3 also includes a support plate 304, the outer surface of the support plate 304 is fixedly connected to the inner wall of the fluidized bed body 1, the upper surface of the support plate 304 is fixedly connected to a stepper motor 306, the output end of the stepper motor 306 is fixedly connected to a rotating shaft 307, and the top end of the rotating shaft 307 is fixedly connected to a turntable 302.

[0055] Four rotating cylinders 305 are fixedly connected to the upper surface of the turntable 302, and the top of each rotating cylinder 305 is in contact with the bottom surface of the fixed plate 224. Four connecting shafts 309 are rotatably connected to the inner wall of the turntable 302, and the outer surface of each connecting shaft 309 is fixedly connected to a rotating gear 308. Four medicine discharge ports 301 are provided on the upper surfaces of the four rotating gears 308, the upper surface of the turntable 302 and the inner bottom walls of the four rotating cylinders 305. A gear ring 303 is fixedly connected to the inner wall of the fluidized bed body 1, and the teeth of the gear ring 303 are respectively meshed with the outer surfaces of the four rotating gears 308.

[0056] When in use, first control the operation of the stepper motor 306. When the stepper motor 306 is in operation, it will drive the rotating shaft 307 fixed at the output end and the turntable 302 fixed at the top of the rotating shaft 307 to rotate, thereby driving the rotating cylinder 305 below the first discharge pipe 209 to rotate. During the rotation of the turntable 302, the connecting shaft 309 connected to the inner wall of the rotating disk 302 will rotate under the action of the meshing relationship between the rotating gear 308 and the gear ring 303. Therefore, when the medicine discharge port 301 opened on the upper surface of the rotating gear 308 coincides with the medicine discharge port 301 opened on the inner bottom wall of the rotating cylinder 305, the medicine will flow out to the inside of the fluidized bed body 1, thereby achieving the purpose of multi-point delivery of medicines, and avoiding the problem of increased failure rate and high cost due to the different forms of medicines and the need for multiple delivery structures.

[0057] like Figure 1 - Figure 4 As shown, a drying mechanism 4 is arranged on the outer side of the fluidized bed body 1, and the drying mechanism 4 includes a heat-insulating plate 407, and the outer surface of the heat-insulating plate 407 is fixedly connected to the inner wall of the circular cylinder 202, and four heating wires 403 are fixedly connected to the inner wall of the circular cylinder 202, and the outer surface of the first extraction pipe 208 is fixedly connected to the second extraction pipe 404, and the outer surface of the second extraction pipe 404 is fixedly connected to the fourth solenoid valve 405, and the outer surface of the circular cylinder 202 is fixedly connected to the first air inlet pipe 401, and the end of the first air inlet pipe 401 away from the circular cylinder 202 is fixedly connected to the filter screen 402, and the outer surface of the fluidized bed body 1 is provided with an exhaust hole 406.

[0058] The outer surface of the fluidized bed body 1 is fixedly connected with a water inlet pipe 6, the outer surface of the fluidized bed body 1 is fixedly connected with a drain pipe 7, and the bottom end of the fluidized bed body 1 is fixedly connected with a sewage pipe 12. By providing the water inlet pipe 6, the drain pipe 7 and the sewage pipe 12, the water inlet pipe 6 is connected with the water outlet of the chemical crystallization granulation fluidized bed system, and the drain pipe 7 is connected with the filtering system, and the sewage pipe 12 is connected with the sludge pump, so as to conveniently discharge the sludge;

[0059] The outer surface of the fluidized bed body 1 is fixedly connected with a fixing ring 8, and the bottom surface of the fixing ring 8 and the bottom end of the circular cylinder 202 are fixedly connected with three supporting legs 10, and the bottom end of each supporting leg 10 is fixedly connected with a circular plate 11. By providing the supporting legs 10 and the circular plates 11, the supporting legs 10 can provide support for the device, and the circular plates 11 can increase the contact area between the equipment and the ground, so that the equipment stands more stably.

[0060] The outer surface of the fluidized bed body 1 is fixedly connected to a second air inlet pipe 9, and the outer surface of the second air inlet pipe 9 is fixedly connected to the inner wall of the fixing ring 8. By providing the second air inlet pipe 9, gas can be input into the interior of the fluidized bed body 1 through the second air inlet pipe 9 to achieve the purpose of fluidization.

[0061] By controlling the operation of the stepper motor 306, the stepper motor 306 will drive the rotating shaft 307 fixed at the output end and the turntable 302 fixed at the top of the rotating shaft 307 to rotate, thereby driving the rotating cylinder 305 below the first discharge pipe 209 to rotate. During the rotation of the turntable 302, the connecting shaft 309 connected to the inner wall of the rotating disk 302 will rotate under the action of the meshing relationship between the rotating gear 308 and the gear ring 303. Therefore, when the medicine discharge port 301 opened on the upper surface of the rotating gear 308 coincides with the medicine discharge port 301 opened on the inner bottom wall of the rotating cylinder 305, the medicine will flow out to the inside of the fluidized bed body 1, thereby achieving the purpose of multi-point medicine delivery and avoiding the problem of increased failure rate and high cost due to the different forms of medicines and the need for multiple delivery structures.

[0062] The working process provided by the present invention is as follows:

[0063] When the present invention is used, first, the gear metering pump 201 is controlled to operate, and the first solenoid valve 207 and the second solenoid valve 211 are controlled to open, and the third solenoid valve 212 and the fourth solenoid valve 405 are controlled to close, and then the gear metering pump 201, the first extraction pipe 208 and the second extraction pipe 404 can be used to extract liquid medicine and air respectively, thereby directly delivering the liquid medicine to a suitable position, and indirectly delivering the powdered medicine and the granular medicine to a suitable position by using the gas, after the liquid medicine is delivered;

[0064] When the gear metering pump 201 is in operation, it will extract the hot air heated by the heating wire 403 inside the circular cylinder 202. The hot air will pass through the first extraction pipe 208 and the first discharge pipe 209, which is the same as the movement track of the liquid medicine. Therefore, the hot air will take out the moisture inside the first extraction pipe 208 and the first discharge pipe 209 during the movement. After completion;

[0065] When the stepper motor 306 is in operation, it will drive the rotating shaft 307 fixed at the output end and the turntable 302 fixed at the top of the rotating shaft 307 to rotate, thereby driving the rotating cylinder 305 below the first discharge pipe 209 to rotate. During the rotation of the turntable 302, the connecting shaft 309 connected to the inner wall of the rotating disk 302 will rotate under the action of the meshing relationship between the rotating gear 308 and the gear ring 303. Therefore, when the medicine discharge port 301 opened on the upper surface of the rotating gear 308 coincides with the medicine discharge port 301 opened on the inner bottom wall of the rotating cylinder 305, the medicine will flow out to the inside of the fluidized bed body 1, thereby reducing capital investment and maintenance frequency.
