Abstract
The utility model discloses a fluidized bed which comprises a main body, a feed port, a discharge port, an air inlet and an air outlet, wherein the main body is hollow, the feed port is arranged on the main body, materials enter the main body through the feed port; the materials are discharged out of the main body through the discharge port after being dried; the air inlet is arranged at the lower end side part of the main body for the hot air flow to enter the main body; and the air outlet is positioned at the top of the main body for the gas flow to go out of the main body. The fluidized bed further comprises a steel plate which is transversely arranged in the position above the air inlet and a plurality of holes are uniformly distributed at a certain distance on the steel plate, wherein the holes are angled relative to the main body of the steel plate. The steel plate with angled holes can enhance the rotation of the air flow, thereby achieving the effects of more complete drying operation and higher efficiency.
Description
Technical field
The utility model relates to a kind of fluid bed, particularly is used for the fluid bed of dried material.
Background technology
Many industries, for example, foodstuff preservation, plastics-production etc., all need in the production process or final material carry out drying, otherwise can cause product perishable or defective.In these industries, conventional drying mode has artificial airing, machine oven dry etc., however these modes often have shortcomings such as place inconvenience, efficient is lower.
For this reason, fluid bed is used to dried material.The fluidized bed type drying equipment is to spray temperature flowing gas (being generally air) at a high speed but supply to handled thing in the apparatus main body from the dispersion plate that is located at the bottom in the apparatus main body to flow and form fluosolids, and handled thing is disperseed, contact with the flowing gas of high temperature simultaneously and make the device of its drying.Such apparatus structure is simple, maintenance and operation easily, and device can miniaturization, takes up an area of fewly, price is low, bigger than other drying device heat capacity coefficients, as can to adapt to the handled thing of large-scale granularity and proportion drying is applied widely.Yet high speed airflow is directly broken through fluosolids and may be caused the material particles drying still abundant inadequately.
The utility model content
The purpose of this utility model provides a kind of fluid bed, its drying efficiency height.
The purpose of this utility model realizes that by a kind of like this fluid bed is provided it comprises, main body, described main body hollow; Charging aperture is located on the main body, enters in the main body for material; Discharging opening is discharged main body for dried material; Air inlet is located at main body lower end sidepiece, and the heat supply air-flow enters main body; Air outlet is positioned at the main body top, and air feed stream flows out main body; Also comprise and be located at the air inlet top position, the steel plate of lateral arrangement is intervally distributed with a plurality of holes uniformly on the described steel plate, and described hole and steel plate main body are angled.
Further, the aperture in described hole is between 5 millimeters to 20 millimeters.
Further, the spacing in described hole and adjacent hole is between 10 millimeters to 50 millimeters.
Further, the angle between the main body of described hole and steel plate is between 30 degree are spent to 60.
Further, described steel plate thickness is roughly 1 millimeter.
Further, the mid portion of described main body is provided with the manhole of coming in and going out for the people, and manhole is provided with valve to be opened/closed.
Further, the mid portion of described main body is provided with observation window.
The beneficial effects of the utility model are mainly reflected in: by a kind of steel plate that has angled hole is provided, increased the rotation of air-flow, made drying more abundant, efficient is higher.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the cutaway view of the specific embodiment of the present utility model.
Fig. 2 is the partial enlarged drawing of the specific embodiment of the present utility model.
Fig. 3 is the vertical view of the steel plate of the specific embodiment of the present utility model.
Wherein:
1 support, 10 air outlets
2 second discharging openings, 12 charging apertures
5 first discharging openings, 13 air inlets
6 manholes, 17 nuts

The specific embodiment
Following with reference to the description of drawings specific embodiment of the present utility model.
Fig. 1 is the profile of the specific embodiment of the present utility model.
As Fig. 1, fluid bed comprises a main body 7, main body 7 roughly be one vertical cylindric, hollow is to provide goods fluid and dry space.
The middle part of main body 7 is provided with charging aperture 12, and material to be dried enters main body 7 by charging aperture 12.The sidepiece of the lower end of main body 7 is provided with air inlet 13, and air inlet 13 can connect blower fan (figure does not show).Thermal current enters main body 7 by air inlet 13, is flowed out by the air outlet 10 that is positioned at main body 7 tops again.In the process that thermal current flows out, thermal current is in main body 7 moved upward inside, flow through material particles, if its flow velocity is enough big, material particles will be no longer descends under the gravity effect and by the frictional force institute support of fluid, have the character of many class quasi-fluids, enter fluidization, material particles disperses also by even, dry fully in this process.
The mid portion of main body 7 is provided with a manhole 6, and manhole 6 is provided with gate to be opened/closed, is used for entering the inside of main body 7 for operation or maintenance personal when detecting and keep in repair fluid bed.The mid portion of main body 7, the top of manhole 6 are provided with an observation window, and the confession operating personnel observe the dry materials situation in the main body 7.The lower end of main body 7 also is provided with a support 1 that is used for supportive body 7.
Main body 7 is provided with at least one discharging opening, and is concrete, and main body wall is provided with one first discharging opening 5, and the bottom is provided with one second discharging opening 2.
As Fig. 2 and Fig. 3, the top position of the air inlet 13 of main body 7 is horizontal is provided with steel plate 19, and steel plate 13 is supported by bearing 18, and bearing 18 is provided with nut 17 firmly to grip steel plate 19.Steel plate 19 about 1 millimeters thick are intervally distributed with the hole of some certain specifications uniformly, and there is certain regulation in the spacing of the opinion in each hole, aperture.Hole and steel plate 19 main bodys are angled, make air-flow form rotating flow, more help the boiling of material particles, finally reach and fully the contacting of air, and add large contact surface, strengthen drying efficiency.Concrete, the aperture in hole is generally between 5 millimeters to 20 millimeters, and pitch-row is between 10 millimeters to 50 millimeters, and the hole becomes 30 degree to spend to 60 with angle between steel plate 19 main bodys.
Although be the example purpose, preferred implementation of the present utility model is disclosed, but those of ordinary skill in the art will recognize that under situation about not breaking away from by the disclosed scope and spirit of the present utility model of appending claims, various improvement, increase and replacement are possible.
