Description

Technical Field

[0001] The utility model relates to the technical field of fluidized beds, in particular to a discharging device for a fluidized bed. Background Art

[0002] A fluidized bed reactor uses gas or liquid to pass through a layer of granular solids, placing the solid particles in suspension and allowing for gas-solid or liquid-solid phase reactions. When used in gas-solid systems, it is also known as a fluidized bed. Fluidized bed technology is widely used in the chemical, metallurgical, energy, and environmental protection industries to achieve processes such as mixing, drying, and reacting solid particles.

[0003] Nowadays, fluidized beds are discharged through the discharge device below them after the fluidization reaction. However, the discharge pipe below the fluidized bed is prone to material blockage, especially when a large amount of material is discharged. After the blockage, the fluidized bed needs to be manually stopped and then dredged, which will affect the subsequent discharge efficiency of the fluidized bed.

[0004] Therefore, it is necessary to design a fluidized bed discharge device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a discharge device for a fluidized bed to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A discharge device for a fluidized bed comprises a reactor body, the bottom of which is fixedly connected to a plurality of support frames, a feed pipe, an air inlet pipe and an air outlet pipe being respectively arranged on the periphery of the reactor body, and a discharge pipe being arranged below the reactor body.

[0008] As a preferred solution of the present invention, a sliding tube is provided above the interior of the discharge tube. The diameter of the sliding tube is smaller than the internal diameter of the discharge tube and the sliding tube is slidably connected to the interior of the discharge tube.

[0009] As a preferred solution of the present invention, a pressure plate is fixedly connected to the outer side of the top of the sliding tube, a spring mounting groove is opened inside the lower part of the reactor body, a spring is installed inside the spring mounting groove, and the top side of the spring is fixedly connected to the bottom of the pressure plate.

[0010] As a preferred solution of the present invention, two vibration motors are further fixedly mounted on the outer shell of the discharge pipe by screws. The two vibration motors are arranged parallel to each other and are of the same model and power.

[0011] As a preferred solution of the present invention, a number of deceleration plates are correspondingly provided on the inner wall of the sliding tube, which are staggered up and down. The bottoms of the several deceleration plates are also rotatably connected to electric telescopic rods through hinges, and the side of the electric telescopic rod away from the deceleration plate is also rotatably connected to the inner wall of the sliding tube through a hinge.

[0012] As a preferred solution of the present invention, a controller is fixedly mounted on the outer shell of the reactor body, and the controller is respectively connected to the control end of the vibration motor and the electric telescopic rod in telecommunication.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the utility model, a discharge device of a fluidized bed is set up. When the fluidized bed is used, when the material is discharged from the discharge pipe at the bottom, two vibration motors can be started at the same time. The directions of the two vibration motors are opposite. In this way, the two motors run synchronously, so that the discharge pipe produces linear vibration, thereby realizing up and down vibration between the discharge pipe and the sliding pipe, reducing blockage inside the discharge pipe; by setting an adjustable angle deceleration plate inside the sliding pipe, the impact force of the material entering the discharge pipe can be slowed down, further reducing the discharge stability.

[0025] In this embodiment, a sliding tube 7 is provided above the interior of the discharge tube 6. The diameter of the sliding tube 7 is smaller than the internal diameter of the discharge tube 6 and is slidably connected to the interior of the discharge tube 6; a pressure plate 8 is fixedly connected to the outer side of the top of the sliding tube 7, and a spring mounting groove 9 is provided inside the lower interior of the reactor body 1. A spring 10 is installed inside the spring mounting groove 9, and the top side of the spring 10 is fixedly connected to the bottom of the pressure plate 8; two vibration motors 11 are also fixedly installed on the outer shell of the discharge tube 6 by screws. The two vibration motors 11 are arranged parallel to each other and are of the same model and power; by starting the two vibration motors 11 at the same time, the two vibration motors 11 have opposite directions, so that the two vibration motors 11 operate synchronously, so that the discharge tube 6 generates linear vibration, thereby realizing up and down vibration between the discharge tube 6 and the sliding tube 7. The up and down vibration can accelerate the discharge speed inside the discharge tube 6 and avoid blockage inside the discharge tube 6.

[0026] In this embodiment, a number of deceleration plates 12 are correspondingly provided on the inner wall of the sliding tube 7, which are staggered up and down. The bottom of the deceleration plates 12 is also rotatably connected to an electric telescopic rod 14 through a hinge 13. The side of the electric telescopic rod 14 away from the deceleration plate 12 is also rotatably connected to the inner wall of the sliding tube 7 through the hinge 13; the deceleration plate 12 is used to slow down the speed at which the material falls into the inside of the discharge pipe 6, reducing its impact force on the inner wall of the discharge pipe 6, thereby further improving the discharge stability.

[0027] Among them, a controller is also fixedly installed on the outer shell of the reactor body 1, and the controller is respectively connected to the control ends of the vibration motor 11 and the electric telescopic rod 14 by telecommunication; the vibration motor 11 and the electric telescopic rod 14 can be regulated by the controller, including the start and stop of the vibration motor 11, the vibration frequency, etc., and the start and stop of the electric telescopic rod 14.

[0028] The working process of the present invention is as follows: when the discharge device of the fluidized bed is used, the material undergoes a fluidization reaction inside the reactor body 1, and the material after the reaction reaches the inside of the discharge pipe 6 below through the slope, and is discharged through the discharge pipe 6. In the process of discharging, the two vibration motors 11 are started at the same time, and the directions of the two vibration motors 11 are opposite. In this way, the two vibration motors 11 operate synchronously, so that the discharge pipe 6 produces linear vibration, thereby realizing the up and down vibration between the discharge pipe 6 and the sliding pipe 7. The up and down vibration can accelerate the discharge speed inside the discharge pipe 6 and avoid blockage inside the discharge pipe 6; the deceleration plate 12 is used to slow down the speed at which the material falls into the inside of the discharge pipe 6, reducing its impact force on the inner wall of the discharge pipe 6, thereby further improving the discharge stability.
