Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
The fluidized bed is provided with a fluidized bed furnace, positive and negative pressure is arranged in the fluidized bed furnace, namely positive pressure gas is arranged at the position, close to the fluidized bed furnace, of the powder, negative pressure is arranged above the fluidized bed furnace, and the positive and negative pressure are staggered to promote the powder to be stirred so as to promote the whole drying.
Examples
The present embodiment provides a sampling device which is arranged on the side of the fluidized bed furnace close to the positive pressure, and the intention of the design is to facilitate the pushing of the gas-powder mixture by the positive pressure gas, so that the whole gas-powder mixture can be pushed to the position of the bin outlet 100.
Specifically, in order to enhance the discharging effect, a negative pressure device 200 is arranged at the bin outlet 100, and the negative pressure device 200 is used for matching with the positive pressure in the fluidized bed furnace to realize the rapid and large-amount transportation of the whole gas-powder mixture.
And during material taking, material can be taken at the air extraction opening of the negative pressure device 200 or the negative pressure device 200 can be made to realize interval adsorption to material accumulation for material taking.
In order to have a certain buffering and good material taking effect in the whole material taking process, an L-shaped material outlet 300 is arranged at the material bin outlet 100, the material outlet 300 gives a good transition process to the material from the material bin outlet 100, and a sampling material port at the other end of the L-shaped material outlet 300 is connected with the negative pressure device 200. However, in a general material taking process, because there is a height between the material taking opening and the material bin outlet 100, if the height of the material taking opening is higher than that of the material bin outlet 100, the overall material taking effect is poor and a negative pressure which needs to consume more pairs is generated to take materials, and if the height of the material taking opening is shorter than that of the material bin outlet 100, the material taking effect is good and the material taking efficiency is high.
However, during material taking, since there is no means to retain the powder and the material needs to be taken by the opening and closing of the negative pressure device 200, and even if the material is taken by the opening and closing of the negative pressure device 200, most of the material still remains in the negative pressure device 200. In order to avoid the above problems, a filter element 400 is disposed before the negative pressure device 200, powder is retained on the filter element 400, and the material can be taken only by directly taking down the filter element 400 when taking the material.
Examples
However, in order to achieve better material removal, the overall removal, material transport and removal are optimized.
Wherein, be connected with feed bin export 100 is a discharging pipe 300 that is T shape, and the middle part export of this discharging pipe 300 is connected and is linked together with feed bin export 100, and the upper end export is connected and is linked together with negative pressure device 200, and the lower extreme export sets up the sample feed bin.
And a filter element 400 is arranged above the sampling port and near the upper outlet. By this arrangement, the negative pressure in combination with the positive pressure causes the gas-powder mixture to converge upward until the gas is discharged from the upper outlet and the powder adheres to the filter element 400.
The powder attached to the filter element 400 can fall to the sampling port along the gravity, thereby realizing the sampling effect of the material. However, this sampling effect has a problem that the total sampling amount and sampling time are not controllable, which is determined by the gravity of the powder and the adhesive force between the powder and the filter element 400. Therefore, a material scraping mechanism 500 is arranged in the integral sampling device, and the material scraping mechanism 500 mainly separates the powder on the filter element 400 from the filter element 400 and falls to a sampling material opening.
In general, the flicking mechanism 500 may take the following forms:
1. a vibration mechanism is provided on the side wall of the cartridge 400, such as a vibration motor provided on the side wall of the cartridge 400, which vibrates at intervals to vibrate material from the cartridge 400 down and into the sampling port.
2. An air blowing device 501 is arranged on the side wall of the T-shaped discharging pipe 300, an air blowing port of the air blowing device 501 is communicated with the filter element 400, and the air blowing path of the air blowing device 501 is a path from the air blowing device 501 to the filter element 400 and then to the lower end outlet. And because the gas blowing device 501 is operated with a gap in order to prevent a part of the gas from converging toward the middle outlet, the gas blowing device 501 is prevented from obstructing the collection of the gas-powder mixture.
More, in order to ensure a good material taking effect, valve bodies 600 are respectively provided at the middle outlet, the lower outlet and the upper outlet.
For example, when the negative pressure device 200 works, only the valve body 600 at the lower end outlet can be closed, so that the circulating gas-powder mixture is sucked into the filter element 400; when the material is required to be shaken, the upper end outlet and the middle outlet are closed, the air blowing equipment 501 works, and powder is blown to the lower end outlet, so that the sampling effect is realized; the valve body 600 of the lower outlet, the middle outlet and the upper outlet may be closed when sampling is not required. The whole equipment has wide applicability, is suitable for sampling under different conditions, and has good sampling effect and high efficiency.
Examples
The third embodiment is based on the second embodiment.
Embodiment three provides a ebullated bed with a sampling device as in embodiment two. Wherein the sampling device is arranged on one side of the fluidized bed close to the inside of the positive pressure furnace. The collection of the gas-powder mixture is realized by means of the positive pressure of the boiling bed and the negative pressure of the sampling device.
The boiling bed is convenient for sampling, has a simple structure, and realizes good drying and sampling monitoring effects.
Because the boiling bed is provided with the negative pressure device 200, in order to save equipment and improve the utilization rate of the equipment, the sampling device and the boiling bed can share one negative pressure device 200, namely the negative pressure device 200 of the boiling bed is provided with a branch circuit, and the branch circuit is directly connected with the upper end cavity of the boiling bed, so that the negative pressure at the upper end of the boiling bed is realized.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
