Abstract
The utility model discloses a fluidized bed, which consists of a new feeding cylinder and a crushing cavity, wherein the inner diameter of the new feeding cylinder is consistent with the inner diameter of the crushing cavity; the outer diameter and the hole pitch of the lower flange of the crushing cavity are consistent with the outer diameter and the hole pitch of the upper end surface of the crushing cavity in size; the new feeding cylinder is positioned above the crushing cavity, and the lower flange of the new feeding cylinder is directly jointed and fixed with the upper end surface of the crushing cavity. The fluidized bed sealing device can reduce material consumption and labor cost in the manufacturing process, and meanwhile, reduces the part assembling joint surface of the fluidized bed, and ensures better sealing property.
Description
Technical Field
The utility model relates to powder equipment, in particular to a jet mill of the powder equipment.
Background
The existing fluidized bed is shown in the attached figure 1 of the specification and consists of a feeding cylinder body 1, a transition flange 2 and a crushing cavity 3. The feeding cylinder body 1 is positioned above the crushing cavity 3 and is connected with the crushing cavity 3 through a transition flange.
During the operation of the fluidized bed, powder particles enter the feeding cylinder 1 through the feeding port of the feeding cylinder 1 and fall into the crushing cavity 3 below the feeding cylinder, and the airflow crushing function of the powder particles is realized under the action of supersonic airflow.
The prior fluidized bed has the following defects: reinforced barrel 1 is connected through transition flange 2 with smashing chamber 3, and the structure is too loaded down with trivial details, has increased material consumption and human cost. Moreover, too many joint surfaces may result in reduced sealing properties and may not meet customer requirements.
Disclosure of Invention
The utility model aims to overcome the defects of the prior technical scheme, and the structure of the novel crushing device is improved by removing the intermediate transition flange 2, adopting the mode that the novel feeding cylinder body 4 is directly jointed with the upper end surface of the crushing cavity 3 and is tightly connected by bolts, so that the structure is more simplified, the sealing performance is more reliable, and the social requirements are met.
The technical scheme of the utility model is as follows:
a fluidized bed, it is made up of new charging cylinder 4, pulverize cavity 3, characterized by that, its new charging cylinder 4 internal diameter is identical to pulverizing the internal diameter size of the cavity; the outer diameter and the hole pitch of the lower flange of the crushing cavity are consistent with the outer diameter and the hole pitch of the upper end surface of the crushing cavity 3; the new charging barrel 4 is positioned above the crushing cavity 3, and the lower flange of the new charging barrel is directly jointed and fixed with the upper end surface of the crushing cavity 3.
According to the utility model, the new charging barrel 4 is directly jointed with the upper end surface of the crushing cavity 3 and tightly connected by bolts, so that the structure is more simplified, the sealing performance is more reliable, the transition flange 2 is removed, the material consumption and the labor cost in the manufacturing process are reduced, meanwhile, the part assembly joint surface of the fluidized bed is reduced, and the better sealing performance is ensured. Makes up the defects of the existing fluidized bed and can achieve the aim of the utility model.
Drawings
FIG. 1 is a schematic diagram of a conventional fluidized bed, and FIG. 2 is a schematic diagram of a fluidized bed according to the present invention. In the figure, 1 is a feeding cylinder, 2 is a transition flange, 3 is a crushing cavity and 4 is a new feeding cylinder.
Detailed Description
The utility model is illustrated in the accompanying drawings, and figure 2 is an example of the utility model. It comprises a crushing cavity 3 and a newly added cylinder 4. The inner diameter of the new charging barrel 4 is consistent with the inner diameter of the crushing cavity, the outer diameter and the hole pitch of the lower flange of the new charging barrel are consistent with the outer diameter and the hole pitch of the upper end surface of the crushing cavity 3, the new charging barrel 4 is positioned above the crushing cavity 3, and the lower flange of the new charging barrel is directly jointed with the upper end surface of the crushing cavity 3 and is tightly connected with the upper end surface of the crushing cavity 3 through bolts.
During the operation of the fluidized bed, powder particles enter the feeding cylinder 1 through the feeding port of the feeding cylinder 1 and fall into the crushing cavity 3 below the feeding cylinder, and the airflow crushing function of the powder particles is realized under the action of supersonic airflow.
Trial verification proves that the novel charging barrel 4 is directly jointed with the upper end surface of the crushing cavity 3 and is tightly connected by the bolts, so that the structure is more simplified, the sealing performance is more reliable, the transition flange 2 is removed, the material consumption and the labor cost in the manufacturing process are reduced, the part assembling joint surface of the fluidized bed is reduced, and the better sealing performance is ensured. The fluidized bed has simple and reliable structure and low manufacturing cost, makes up the defects of the existing fluidized bed and can achieve the aim of the utility model.
