Abstract
The utility model relates to a steam inner-heated gypsum continuous converter. Aiming at solving the technique problem, the utility model provides a steam inner-heated gypsum continuous converter which has the advantages of simple and compact structure, high heat transfer efficiency and low energy consumption, and can ensure a continuous production without dead halt. In order to solve the problem, the utility model adopts the technical scheme that the steam inner-heated gypsum continuous converter is provided with a casing; a feed opening, an air inlet and an air outlet are formed at the top part of the casing; and a discharge opening is formed at the bottom part. The converter is characterized in that a settling chamber is arranged in the casing; a group of hollow shafts arranged on the same horizontal plane are distributed at the bottom part of the settling chamber; hollow blades communicated with the hollow shaft are evenly arranged on each hollow shaft; the hollow blades on the adjacent hollow shafts are matched with one another; one end of the hollow shaft is connected with a rotary joint; the output shaft of a motor is connected to a transmission gear; the output shafts of the transmission gear are as many as the hollow shafts and are connected with the hollow shafts through an air seal device. The converter provided by the utility model can be used for continuously calcining gypsum.
Description
Technical field
The utility model relates to the continuous convertor of a kind of gypsum, and the continuous convertor of particularly a kind of steam internal heat type gypsum mainly is applicable to the continuous calcining of gypsum, to obtain the β semi-hydrated gypsum.
Background technology
As far back as the domestic exploitation of just carrying out the gypsum drying machine seventies, it is too complicated to be limited to technical qualification at that time and designed hot box structure, so Halfway Stopping.Along with the introduction of overseas equipment, the data of domestic this respect is on the increase, and has all carried out new improvement in all respects such as structures, is used at present mud oven dry in the water treatment and the sludge in the ore dressing industry more and dries.Present most of type only is applicable to periodical operation, and can't be used in the production of powder-like product, and also can't adapt to has the continuous production of being strict with terra alba to the finished product water ratio.
Summary of the invention
The technical problems to be solved in the utility model is: at the problem of above-mentioned existence provide a kind of simple and compact for structure, heat transfer efficiency is high, energy consumption is low, and can guarantee the continuous convertor of steam internal heat type gypsum that continuous production does not crash, gas usage is few in the calcination process, can significantly reduce the load of dust removal installation, obtain high-quality β semi-hydrated gypsum.
The technical scheme that the utility model adopted is: the continuous convertor of steam internal heat type gypsum, has shell, its top is respectively equipped with opening for feed, inlet mouth and air outlet, the bottom has discharge port, it is characterized in that: establish settling pocket in the described shell, one group of quill shaft that is positioned on the same horizontal plane is arranged in the settling pocket bottom, the hollow paddle that is communicated with it evenly is set on the every quill shaft, hollow paddle on the adjacent quill shaft cooperatively interacts, described quill shaft one end connects swivel joint, the output shaft of motor is connected to transmission mechanism, and the number of this transmission mechanism output shaft is consistent with the quill shaft number, and is connected with quill shaft by air seal set.
Interior, the close discharge port place of described settling pocket is provided with the material level switchboard.
Described hollow paddle is a spirrillum, and its pushing spiral angle α is the 9-15 degree, and dorsal horn β is the 2-5 degree; The side is the fan annular, and its angle γ is that 110 degree are to 130 degree.
The beneficial effects of the utility model are: the utility model adopts quill shaft and hollow paddle structure to dry gypsum, and heat transfer area is big in the not only compact construction, and unit volume, has improved heat transfer efficiency greatly; Hollow paddle is designed to spirrillum, when gypsum is carried out stirring and drying, utilizes the hollow paddle of volution that the gypsum of oven dry is delivered to discharge port, has guaranteed the continuity of production process.In addition, the utility model gas usage is few, greatly reduces the load of dust removal installation.

Embodiment
As shown in Figure 1 and Figure 2, present embodiment has shell 1, and its top is respectively equipped with opening for feed 2, inlet mouth 3 and air outlet 4, and the bottom has discharge port 5.Establish settling pocket 6 in the described shell, one group of quill shaft 7 that is positioned on the same horizontal plane is arranged in settling pocket 6 bottoms.In this example, quill shaft 7 numbers are four, and the hollow paddle 8 that is communicated with it evenly is set on the every quill shaft 7, and the hollow paddle 8 on the adjacent quill shaft 7 cooperatively interacts; As shown in Figure 3, Figure 4, in this example, hollow paddle 8 is a spirrillum, and its pushing spiral angle α is 12 degree, and dorsal horn β is 3 degree; The side is the fan annular, and its angle γ is 120 degree.Described quill shaft 7 one ends connect swivel joint 9, these swivel joint 9 the other ends are connected to vapour source, the output shaft of motor 10 is connected to transmission mechanism 11, and the number of this transmission mechanism output shaft is consistent with quill shaft 7 numbers, and is connected with quill shaft 7 by air seal set 12.
Described settling pocket 6 interior, close discharge port places are provided with material level switchboard 13, so that the control mass flow.
The principle of work of present embodiment is: during the calcining operation, steam enters in quill shaft 7 and the hollow paddle 8 by swivel joint 9, and with quill shaft 7 and 8 heating of hollow paddle; Material and warm air enter in the settling pocket 6 by opening for feed 2 and inlet mouth 3 respectively simultaneously, and heated quill shaft 7 and hollow paddle 8 are rotated under the drive of motor 10, thereby material is stirred and dry generation β semi-hydrated gypsum.Because hollow paddle 8 be volution, and the pushing spiral angle α that is provided with is greater than dorsal horn β, thereby when stirring, progressively the material of drying pushed to discharge port 5 and carry out discharging; Meanwhile, because the cause that warm air rises, the material moisture evaporated is promoted to discharge from the air outlet 4 at top from bottom to top by warm air.So constantly circulation can continuous uninterrupted be produced the β semi-hydrated gypsum.
