Description
Technical field
The utility model relates to blast apparatus technical field, particularly a kind of multistage centrifugal blower.
Background technique
Saccharomycete is some unicellular fungi, the unit of not phylogeny classification.Saccharomycete is the microorganism being employed the earliest in history of human civilization.Modern society, saccharomycete is used in industrial production and daily life thereof in a large number, and yeast industry also develops into an important industry.
In the industrial production of yeast, sewage can be produced equally, mud, the environmental protection of yeast industry is a problem being not easy to solve very much always, but is the problem having to solve, and my company's major product is yeast and yeast extract, its sewage sludge produced especially in industry a troubling problem in the processing procedure of sewage, sewage aeration is a critical step, and it can prevent pond inner suspension body from sinking, and strengthens the object that in pond, organic substance contacts with microorganism and dissolved oxygen.Thus in guarantee pond microorganism under the condition having sufficient dissolved oxygen, to oxygenolysis organic in sewage.
At present, the method for aeration is mainly divided into two kinds, mechanical aeration and blast aeration.And blast aeration can adopt multistage centrifugal blower and single-stage centrifugal blower.
Mechanical aeration mainly makes waste water and mud in activated sludge process aeration tank fully mix by machinery (as blade, impeller etc.), and the continuous renewal of mixed solution liquid level is contacted with air, increases the method for the dissolved oxygen in water.Mechanism by means of blade, impeller, sprinkler or turbine device makes the oxygen in air enter liquid.The aerator extensively adopted at present mainly contains surface aeration machine and immersion type turbine aerator two class.In addition, it also can refer to carry out aeration by machinery to water body, air is made to enter in water body, this kind of equipment mainly contains the Mechanical aerator of the supporting special aeration head of aeration blower and connecting tube composition. but this aeration method is simple by the equipment that affects of its design, is only only applicable to for less aeration tank.
Secondly, blast aeration, single-stage centrifugal blower operation relative complex, require below 28 DEG C especially, otherwise lubrication system is easily atomized to cooler-water temperature.Need cooling water > 6t/h, institute's saving power water that is cooled digested.Fear to have a power failure, have a power failure suddenly, top position water tank cannot meet the feed lubrication of blower inertia rotation in 20 minutes, and generation main shaft, bearing shell burn.Single-stage centrifugal blower: noise >=110dB (A), the low frequency noise of noise source mainly overdrive gear, so it must increase sound insulation house, heat dissipation problem is difficult to solve.Single-stage centrifugal blower: thin oil lubricant, Long-Time Service Leakage is universal phenomenon.Adopt sliding bearing, gear up, bearing shell and gear life are 2 years, because rotating speed is high, impeller often need repair balance, otherwise can cause vibration, so frequency of maintenance is higher, makes land used without highi degree of accuracy dynamic balancing machine, must keep in repair the place of origin back and forth, the cost of repairs is expensive, and standby redundancy is more.
Summary of the invention
In order to solve the problem, the utility model provides a kind of multistage centrifugal blower, this blower comprises public base, be located at the reducing motor on public base, the lubrication system be located at the main frame on public base and be located on public base, the main shaft of described main frame is connected with reducing motor by direct-connected coupling, described main frame comprises casing, main shaft, bearing and 6-10 the impeller be located on main shaft, one end of described casing is provided with intake grill, the other end of casing is provided with exhaust outlet, the two ends of described main shaft are connected with casing by bearing, the sealing oil box of described bearing is connected with lubrication system by pipeline, described casing is divided into multiple Seal cage, an impeller is provided with in each Seal cage, between adjacent seals chamber, all labyrinth sealing is adopted between the Seal cage at two ends and casing.
Wherein, the lubrication system in the utility model embodiment comprises top petrol tank, oil purifier and cooling water tank, and described top petrol tank and cooling water tank are located on public base, and described top petrol tank, oil purifier are connected by pipeline successively with the sealing oil box of bearing.
The beneficial effect of the multistage centrifugal blower that the utility model embodiment provides is:
The first, this blower operation is simple; The cooling water of 25kg/h is only needed during operation; Not high to water temperature, water quality requirement; Be not afraid of unexpected power failure.
The second, do not increase any sound arrester, the noise≤84dB (A) of blower own, and be high frequency noise, as long as there is obstacle to get final product flat, so the outer noise free of wind machine room.
