The specific embodiment
below in conjunction with accompanying drawing, the present invention is elaborated:
With reference to Fig. 1, a kind of sewage disposal agitating device, comprise motor 2, decelerator 3, positive coupling 23, shell, shaft 5, impeller 16 and blade 6, described motor 2 is all arranged in shell with decelerator 3, motor 2 is connected with the power shaft of decelerator 3, the output shaft of decelerator 3 is connected by positive coupling 23 with shaft 5 one end, shaft 5 other ends stretch out shell setting and impeller 16 are installed, on impeller 16, be connected with blade 6, its special character is: between impeller 16 and blade 6, by blade coupling assembling, be connected, described blade coupling assembling comprises impeller sleeve 22, retaining ring 19, backstay 20, blade sleeve 17 and spring knock pin 18, impeller sleeve 22 is arranged on impeller 16, on the sidewall of impeller sleeve 22, offer clearance channel, retaining ring 19 is sheathed on impeller sleeve 22, backstay 20 one end are arranged in the endoporus of impeller sleeve 22, the other end is arranged in the endoporus of blade sleeve 17, the other end of blade sleeve 17 and blade 6 are bolted, between the endoporus of described backstay 20 and impeller sleeve 22 and backstay 20 and the endoporus of blade sleeve 17, be interference fits, on the sidewall of described blade sleeve 17, along same bus, be laid with some positioning through hole, on described backstay 20, offer vertically groove, the position of groove is corresponding with the position of positioning through hole on blade sleeve 17, groove is embedded with a spring knock pin 18.By pressing spring knock pin 18 downwards, blade sleeve 17 and backstay 20 are done relative motion vertically, capable of regulating stirs diameter.During installation, the angle of inclination of blade 6 is defaulted as 60 degree, and this angle can be adjusted according to actual needs.Due to impeller sleeve 22 and backstay 20 interference fits, in the time need to adjusting the angle of inclination of blade 6, can rotate backstay 20 until suitable angle, then utilize the retaining ring 19 clamping positioning instants can.Described blade 6 adopts vinylite to make.Can strengthen wearability, improve service life.On above-mentioned lower casing 4, on outer wall, along same even circumferential, be distributed with some gripper shoes 8, gripper shoe 8 outer ends are provided with bearing pin 7a, and bearing pin 7a lower end is provided with roller 7b.
With reference to Fig. 2, in order to realize Fast Installation and dismounting, the shell of sewage agitating device is divided into upper casing 1 and lower casing 4, and upper and lower shell adopts and fastens, and upper and lower shell screws and with bolt, connects afterwards.Fig. 3 a is the internal structure of upper casing, and its inner ring is uniformly distributed with 6 tabs along the circumference.From Fig. 3 b: there is a circle groove at the rear of tab, can be used for installing the tab on lower casing.Fig. 4 is the structure of lower casing 4, from Fig. 4 b: lower house interface outer ring 6 tabs that are also uniformly distributed along the circumference.When upper lower casing is installed, the position of adjusting upper casing 1, makes the tab of lower casing 4 can enter by the gap between upper casing 1 tab Fig. 3 b further groove, and then by upper casing 1 60 degree that turn clockwise, the tab of lower casing 4 has been stuck in to the rear of tab on upper casing 1, thereby has realized locking.
During upper and lower disassembling shell, upper casing 1 is rotated counterclockwise to 60 degree, the tab of lower casing 4 can pass through the opening position between upper casing 1 tab, thereby separated with upper casing 1.For reaching the effect sealing between upper and lower shell, the sealing ring of rubber is placed in the place that upper casing 1 contacts with lower casing 4.
The present invention be by motor as drive unit, through decelerator and shaft coupling, drive straight-arm rotation to make colloidal solid flocculation form larger particle, in order to precipitation, to meet the requirement of purification of water quality in water treatment.
With reference to Fig. 5: be uniformly distributed six blades 6 on agitator arm 16.The thickness of blade 6 is root thickness 3mm, blade tip thickness 2mm, and interior thickness is the transition gradually that blade root arrives blade tip.Impeller 16 adopts key to be connected with stirrer shaft 5.Blade 6 roots are fixedly mounted on blade sleeve 17, after wearing and tearing appear in blade 6, pull down connecting bolt, can extract damage blade from sleeve 17, the blade 6 more renewing.Realized the quick-detachment replacing that damages blade.
With reference to Fig. 5 (b), Fig. 5 (c): have row's aperture on blade sleeve 17, backstay 20 adopts interference fits with sleeve 17, is processed with a dovetail groove on backstay, and groove is embedded with a spring knock pin 18, and spring knock pin 18 can be depressed or eject.As shown in Figure 5 c: when needs are adjusted blade stirring diameter, press spring knock pin 18 downwards, spring knock pin 18 is pushed back the aperture inside of blade sleeve 17, at this moment the alignment restrictions between blade sleeve 17 and backstay 20 is disengaged, the two can do relative motion vertically, until pressing spring ejector pin 18 upwards snaps in another aperture of blade sleeve 17 under bounce effect, the relative motion restriction between blade sleeve 17 and backstay 20 will be resumed again.If position is still improper, can continue above-mentioned steps, until adjust blade stirring diameter, meet job requirement.
Blade 6 adopts hinging type, and angle of inclination can be according to actual conditions adjustment.Generally, rake angle degree is defaulted as 60 degree, and this angle can be adjusted according to actual needs, has been evenly arranged 6 impeller sleeves 22 on impeller 16, and insert in impeller sleeve 22 one end of backstay 20, the two interference fits.As shown in Fig. 5 d: impeller sleeve ends has a gap, when retaining ring 19 is enclosed on impeller sleeve 22, can play locking effect.In the time need to adjusting the angle of inclination of blade 6, unclamp the clamping screw 21 in retaining ring 19, can up time or inverse time rotation backstay 20, adjust blade 6 to suitable angle of inclination, tighten clamping screw 21, retaining ring 19 is clamped, and relative the rotatablely moving of impeller sleeve 22 of backstay 20 is restricted.
In the process of sewage disposal, if the installation and removal of sewage stirring machine can be carried out without draining-off sewage, will save very large manpower and materials so.The invention still further relates to the mounting means of a kind of agitating device in pond:
The determining as shown in Figure 6 of mixer position in pond: for circle and the larger pond of volume, a sewage stirring machine is installed and can not be met sewage disposal needs, therefore should being installed in pond, three sewage stirring machines stir dead angle to reduce, three mixers are evenly distributed in round pool 12, in Fig. 7, " * " locates to represent the installation site of sewage stirring machine in pond, and cylindrical is the edge in pond 12.
