Abstract
The utility model discloses an air-floating air inlet device which comprises a principal shaft (8), an impeller (3) and a bearing (5). The utility model is characterized in that the impeller (3) and an ventilation chamber (7) are connected with a below sealing device (2); the principal shaft (8) and the ventilation chamber (7) are connected with a sealing device (6) which is arranged between them; the ventilation chamber (7) is externally communicated with a ventilation pipe (1). The utility model can make air in the ventilation chamber be isolated from water and others, air and water in the ventilation chamber be blocked off a submersible motor or the bearing, and air enter into water through the ventilation pipe, the ventilation chamber and the impeller. The utility model has compact structure and good sealing effect avoiding using a hollow spindle.
Description
Affiliated technical field
The utility model belongs to sewage disposal device, is meant a kind of diffuser of air supporting machine especially.
Background technology
The air supporting machine also claims flotation machine, is a kind of sewage disposal device that is used for removing anhydrate oil in water emulsion and dispersed oil.This equipment is by being installed under the liquid and the impeller of high speed rotating, deliver air to the sewage bottom, in water, produce trickle bubble, adhere to the buoyancy aid of formation proportion mutually with the grease in the water, the grain of wadding a quilt with cotton etc. less than water, emerge fast, thereby finish pneumatically supported process, will be removed thing by slag scraper then and scrape to dreg collecting slot, thereby finish the purpose of sewage rough purification.Existing air supporting machine air intake structure adopts tubular shaft for the air supporting machine, and tubular shaft connects with impeller, and tubular shaft surfaces.The deficiency of its existence is: because of the requirement of sewage disposal, impeller must be dark more than 1 meter under water.For avoiding the tubular shaft water inlet, the tubular shaft upper end exceeds water surface certain distance again, causes 2 meters of tubular shaft length overalls nearly, has relatively shorter disadvantage of tooling cost height, the cycle of operation.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved air supporting machine diffuser is provided, and result of use is good.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: main shaft, impeller, bearing is characterized in that: impeller connects with venting cavity by lower sealing device; Between main shaft and venting cavity, be provided with upper sealing device, and the two is linked up, the external ventpipe of venting cavity.
The utility model is taked technique scheme, have following beneficial effect: the utility model seals the leakage path between venting cavity and the impeller owing to lower sealing device, make isolation such as air in the venting cavity and water, upper sealing device seals the leakage path between venting cavity and the main shaft, air, water and submersible machine or plumer block in the venting cavity are separated, and air enters in the water by ventpipe and venting cavity and impeller.The utility model has been avoided use hollow spindle, compact construction, good sealing effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model structure diagram.
Mark among the figure: 1-ventpipe, 2-lower sealing device, 3-impeller, 4-submersible machine, 5-bearing, 6-upper sealing device, 7-venting cavity, 8-main shaft.
Embodiment
By shown in Figure 1, the utility model includes: main shaft 8, impeller 3, bearing 5, and impeller 3 connects with venting cavity 7 by lower sealing device 2; Between main shaft 8 and venting cavity 7, be provided with upper sealing device 6, and the two is linked up, venting cavity 7 external ventpipes 1.
The utility model is divided into two relatively independent parts with driving part and vent portion.Lower sealing device 2 is with the sealing of the leakage path between venting cavity 7 and the impeller 3, and lower sealing device 2 is with isolation such as air in the venting cavity 7 and water; Upper sealing device 6 is with the sealing of the leakage path between venting cavity 7 and the main shaft 8, and upper sealing device 6 separates the air in the venting cavity 7, water and submersible machine 4; Air enters in the water by ventpipe 1 and venting cavity 7 and impeller 3; Venting cavity 7 is fixedly connected with submersible machine 4.When not adopting the submersible machine form, venting cavity of the present utility model also can be fixedly connected with plumer block.The utility model also can be used for the aeration in sewage treatment machine.
Claims (1)
1. air supporting machine diffuser, it includes: main shaft (8), impeller (3), bearing (5) is characterized in that: impeller (3) connects with venting cavity (7) by lower sealing device (2); Between main shaft (8) and venting cavity (7), be provided with upper sealing device (6), and the two is linked up, the external ventpipe of venting cavity (7) (1).
