Abstract
The utility model discloses that a kind of cost is low, the novel fan casing sealing device of good sealing effect, comprise fan casing and thermal-protective coating, also comprise the sealing configuration of multilayer labyrinth knife edge type.Mazy type edge seal structure in the utility model is through the seal form of which floor bending, what this design was not easy to produce dust leakage and can prevent air enters casing, and sealing plane need not be processed, and both provides cost savings, good sealing effect of having got back.
Description
Technical field
The utility model belongs to seal arrangement, particularly relates to the seal arrangement of fan casing.
Background technique
At present, a kind of key equipment to be used in process coal dust being produced rock gas and active carbon by high temperature, that is exactly blower fan, the sealing of high temperature carbon dust fan casing is for a long time all a large problem, and fan casing, as a kind of rotary unit collecting coal dust, can not have leakage in pilot process, traditional casing sealing form is with asbestos rope or rubber pad, easily produce gap between layer and layer plane, oxygen easily enters and carbon dust is burnt, and is easy to produce leakage.
Model utility content
In order to solve the problem, the utility model provides that a kind of cost is low, the novel fan casing sealing device of good sealing effect.
According to an aspect of the present utility model, a kind of novel fan casing sealing device is provided, comprises fan casing and thermal-protective coating, also comprise the sealing configuration of multilayer labyrinth knife edge type.Its beneficial effect is: the mazy type edge seal structure in the utility model is through the seal form of which floor bending, what this design was not easy to produce dust leakage and can prevent air enters casing, and sealing plane need not be processed, and both provides cost savings, good sealing effect of having got back.
In some embodiments, described thermal-protective coating is water jacket.Its beneficial effect is: can reach better effect of heat insulation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model section.
In figure: 1-fan casing, 2-sealing configuration, 3-thermal-protective coating.
Embodiment
Be further described below in conjunction with accompanying drawing 1 pair of the utility model.Accompanying drawing 1 schematically shows the utility model novel fan casing sealing device, as shown in Figure 1, comprise fan casing 1 and thermal-protective coating 2, also comprise the sealing configuration 3 of multilayer labyrinth knife edge type.The sealing configuration 3 of multilayer labyrinth knife edge type, through multilayer bending, is not easy to produce dust and reveals, and can prevent air from entering blower fan, avoid the burning of coal dust and oxygen simultaneously.
Preferably, in order to reach the better effect of heat insulation of fan casing, described thermal-protective coating 3 is water jacket.
Above-described is only mode of executions more of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from creation design of the present utility model; can also make other distortion and improve, these all belong to protection domain of the present utility model.
Claims (2)
1. novel fan casing sealing device, comprises fan casing (1) and thermal-protective coating (2), it is characterized in that, also comprises the sealing configuration (3) of multilayer labyrinth knife edge type.
2. novel fan casing sealing device as claimed in claim 1, it is characterized in that, described thermal-protective coating (2) is water jacket.
