Spiral sedimentation separation equipment for sewage treatment
Technical Field
The utility model relates to a water treatment technical field, especially a sewage treatment spiral settlement splitter.
Background
The sludge is a necessary product after sewage treatment in sewage treatment plants and sewage stations, and after the sludge which is not treated well enters the environment, secondary pollution is directly brought to water and atmosphere, and serious threat is formed to ecological environment and human activities. Therefore, the sludge is very careful in treatment, and the sludge is basically treated by a sludge dewatering process.
In current sludge dewatering technology, generally select to use the mud desliming machine, general mud desliming machine all is provided with filter pressing equipment, but in industrial water treatment, what the sewage inside subsided not only has mud, still contained a large amount of waste materials, including metal piece, useless mineral aggregate etc. if adopt the mode of filter pressing to dewater, damage the filter cloth very easily.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sewage treatment spiral sedimentation splitter.
In order to achieve the above object, the utility model provides a following technical scheme:
a spiral sedimentation separation device for sewage treatment comprises
A base, a groove body arranged on the base,
the separation device is arranged in the groove body and is fixed by a positioning frame which is arranged at the side of the groove body and is arranged on the protected base, at least one group of limiting plates are arranged on the positioning frame,
the separating device comprises a shell and a shaft body arranged in the shell, wherein one end of the shaft body is provided with a driving device, the shaft body is fixed in a first bearing seat and a second bearing seat which are respectively fixed at two sides of the groove body,
a shaft body between the first bearing seat and the second bearing seat is provided with a helical blade the diameter of which is gradually reduced from the first bearing seat to the second bearing seat, an inner sleeve is arranged on the outer side of the helical blade,
a liquid outlet is arranged at the bottom of the groove body and at one end of the second bearing seat,
a feed inlet is formed in the shell and located at one end of the first bearing seat.
Further, the lower extreme of base is provided with the supporting leg.
Further, a bearing seat outer cover is arranged on the outer side of the second bearing seat.
Further, drive arrangement includes driving motor, and this driving motor sets up on the motor cabinet, and this motor cabinet sets up in one side of base, is provided with the drive wheel on driving motor's motor shaft, and the drive wheel is connected through the belt with the follow driving wheel that sets up on the shaft coupling, the shaft coupling is connected with the axis body.
Furthermore, a driving shell is arranged on the outer side of the connecting belt of the driving wheel and the driven wheel, and the driving shell is connected with a cover body arranged on the outer side of the coupler.
The utility model discloses mainly adopt the mode of spiral sedimentation processing, inside the through-hole that sheathes including the setting by the feed inlet through preliminary concentrated mud enters into screw means, because helical blade's diameter reduces step by primary shaft bearing to secondary shaft bearing for mud can carry out abundant stirring inside screw means, and moisture is deviate from gradually, reaches the purpose from subsiding.

Detailed Description
Detailed description of the preferred embodimentsreferring to fig. 1-4.
The utility model provides a spiral sedimentation separation equipment for sewage treatment, include
The base 102 is provided with a groove body on the base 102, and the lower end of the base 102 is provided with a supporting leg 100.
Separator sets up the inside of cell body to by being located cell body avris and setting up the locating frame 106 on the base 102 of protecting are fixed, be provided with at least a set of limiting plate 111 on the locating frame 106, locating frame 106 is used for blocking the outside casing 105 of separator, limiting plate 111 is used for casing 105's location and fastening.
The separating device comprises a shell 105 and a shaft body 103 arranged in the shell 105, wherein one end of the shaft body 103 is provided with a driving device, the shaft body 103 is fixed in a first bearing seat 113 and a second bearing seat 117, the first bearing seat 113 and the second bearing seat 117 are respectively fixed on two sides of the groove body,
a spiral blade 118 whose diameter is gradually reduced from the first bearing housing 113 to the second bearing housing 117 is provided on the shaft body between the first bearing housing 113 and the second bearing housing 117, an inner sleeve 112 is provided outside the spiral blade 118, and a bearing housing cover 104 is provided outside the second bearing housing 113.
A liquid outlet 120 is arranged at the bottom of the groove body and at one end of the second bearing seat 117,
a feed opening 121 is formed in the housing 105 at one end of the first bearing seat 113.
The driving device comprises a driving motor 108, the driving motor is arranged on a motor base 107, the motor base 107 is arranged on one side of the base 102, a driving wheel 115 is arranged on a motor shaft of the driving motor 108, the driving wheel 115 is connected with a driven wheel 116 arranged on a coupler 114 through a belt, and the coupler 114 is connected with the shaft body 103.
A drive housing 109 is arranged outside the connecting belt of the drive wheel and the driven wheel and is connected to a housing 110 arranged outside the coupling.
The working principle is as follows: the utility model discloses mainly adopt the mode of spiral sedimentation processing, the mud through preliminary concentration is got into to the screw means inside through setting up through-hole 119 on endotheca 112 by feed inlet 121, because helical blade 118's diameter reduces step by step to second bearing seat 117 by first bearing seat 113, start driving motor 108, driving wheel 115 on the driving motor 108 rotates from band pulley 116 through the belt drive, thereby drive shaft coupling 114 and rotate, the shaft coupling drives the axis body and rotates, thereby make mud carry out abundant stirring by helical blade inside the screw means, moisture deviates from gradually, reach the purpose from subsiding.
