Abstract
It the utility model is related to a kind of rotary kiln, and in particular to a kind of rotary kiln of preventing dust injection.The aggregate bin that the utility model includes rotary kiln body, is connected with rotary kiln body, the aggregate bin top are connected to nature blowdown pipe and malleation tracheae, check valve are provided with the natural blowdown pipe.The utility model is provided with check valve on natural blowdown pipe, while nature blowdown pipe tonifying Qi is ensured, prevents interim inverted draft from carrying outside flue gas and arranges, it is therefore prevented that the loss of metalliferous material, ensure that the cleaning of environment.
Description
Technical field
It the utility model is related to a kind of rotary kiln, and in particular to a kind of rotary kiln of preventing dust injection.
Background technology
Cobaltosic oxide calcines generally use rotary kiln continuous calcining, due to needing to ensure sufficient calcining in calcination process
Atmosphere, while consider that in kiln prolonged barotropic state should not be produced, it is necessary to set natural aspiration mouth to compensate coordination, but
It is to have part ash-laden gas to be arranged outside natural gas supplementing opening when stage inverted draft arrives in pulse backblowing, causes metal object
The loss of material, not only bad for economical production, environmental protection, clean manufacturing are less useful for, environment is polluted.
Utility model content
The purpose of this utility model is that a kind of rotary kiln of preventing dust injection is provided the problem of presence for prior art.
Concrete technical scheme of the present utility model is as follows：
A kind of rotary kiln of preventing dust injection, including rotary kiln body, the aggregate bin that is connected with rotary kiln body, the collection
Nature blowdown pipe and malleation tracheae are connected at the top of hopper, check valve is provided with the natural blowdown pipe；
The check valve includes body, the valve element being arranged in the body, and the body is with respect to the horizontal plane vertical, body
Narrowed mouth is inside provided with, valve element, which is located at, to be narrowed below mouth and can be moved up and down along body.
The utility model has the advantages that：
The utility model is provided with check valve on natural blowdown pipe, while nature blowdown pipe tonifying Qi is ensured, prevents
Interim inverted draft is carried and arranged outside flue gas, it is therefore prevented that the loss of metalliferous material, ensure that the cleaning of environment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The rotary kiln of a kind of preventing dust injection as shown in Figure 1, including rotary kiln body 1, the collection that is connected with rotary kiln body 1
Hopper 2, the top of aggregate bin 2 are connected to nature blowdown pipe 3 and malleation tracheae 4, are provided with the natural blowdown pipe 3
Check valve 5, the check valve 5 include body 6, the valve element 7 being arranged in the body 6, and the body 6 with respect to the horizontal plane hangs down
Directly, narrowed mouth 8 is provided with body 6, valve element 7, which is located at, to be narrowed the lower section of mouth 8 and can be moved up and down along body 6.
When natural blowdown pipe 3 is to rotary kiln 1 tonifying Qi of body, valve element 7 leaves narrowed mouth 8 under gravity, and air is by receiving
Slot 8 enters aggregate bin 2 by nature blowdown pipe 3, eventually enters into rotary kiln body 1；When the pulse backblowing of rotary kiln body 1
When, interim inverted draft by rotary kiln body 1 through aggregate bin 2 to natural blowdown pipe 3, in the promotion of interim inverted draft
Under effect, valve element 7 is moved at narrowed mouth 8, blocks narrowed mouth 8, prevents interim inverted draft from being discharged by natural blowdown pipe 3.
Claims (2)
