Vertical automatic chemical feeding device of sewage treatment machine
Technical field
The present invention relates to the automatic chemical feeding device that a kind of sewage treating machine is used, particularly a kind of vertical automatic chemical feeding device of sewage treatment machine.
Background technology
Treating capacity is that the full-automatic traditional drug delivery device of sewage treating machine of 5~600 tons/24 hours series all adopts like the foul water tank supply medicinal powder of the horizontal drug delivery device among Fig. 5 to full-automatic sewage treating machine.
Referring to Fig. 5, horizontal drug delivery device adopts horizontal storage cartridge case and horizontal machine to drive the horizontal power transmission shaft that welded and installed has helical blade, utilizes the screw propulsion principle to supply with medicinal powder to the foul water tank of full-automatic sewage treating machine.Its method of operation is after the medicinal powder of screw propulsion becomes horizontal feed to put in place, transfers to suddenly freely falling the cesspool confession medicine of mode to full-automatic sewage treating machine.Weak point is the easy conglomeration of medicinal powder and looses not open and supply medicine inhomogeneous; Uninterruptedly flow through sewage in the foul water tank of full-automatic sewage treating machine; Administration inhomogeneous causes in the sewage medicinal powder dissolving inhomogeneous easily, and the chemical cleaning method quality that is prone to cause to be processed sewage is unstable.Medicinal powder in the horizontal in addition storage cartridge case is because the gravity effect, causes in the bottom to adhere to residual and be difficult to remove.
Summary of the invention
Technical problem to be solved by this invention provides a kind of vertical automatic chemical feeding device of sewage treatment machine, can realize stablizing, supply with evenly, reliably medicinal powder.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: a kind of vertical automatic chemical feeding device of sewage treatment machine comprises variable-frequency motor; The tapered bucket in cylindrical shell bottom, the lower end is provided with the administration mouth, and the cylindrical shell upper end is provided with dosing mouth; Main shaft is installed in the cylindrical shell through rack sleeve, and main shaft one end is connected with variable-frequency motor, and the other end is connected with spiral administration axle; The other end of spiral administration axle is positioned at the administration mouth, and main shaft is provided with sweeps the medicine blade.
Described rack sleeve two ends are provided with seal.
Described spiral administration axle is provided with helical blade.
Describedly sweep the below that the medicine blade is positioned at cylindrical shell cylinder and circular cone boundary line.
Described cylindrical shell, spiral administration axle, rack sleeve and main shaft material are stainless steel.
Described administration mouth material adopts polytetrafluoroethylene (PTFE).
A kind of vertical automatic chemical feeding device of sewage treatment machine provided by the invention; Through vertically disposed conical shell; Utilize gravity and spiral administration axle to match; Realized that the rounded face of medicinal powder scatters and falls into and the sewage that fully is dissolved in the full-automatic sewage treating machine foul water tank, the chemical cleaning method steady quality of disposing of sewage.The sweeping the medicine blade and can break up the medicinal powder that falls in the cylindrical shell of rotation at a high speed, and sweep in the back taper tube of cylindrical shell bottom.The design of rack sleeve can prolong the service life of main shaft, avoids main shaft and bearing to be corroded by medicinal powder.

The specific embodiment
In Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of vertical automatic chemical feeding device of sewage treatment machine comprises variable-frequency motor 6; The tapered bucket in cylindrical shell 4 bottoms, the lower end is provided with administration mouth 5, and cylindrical shell 4 upper ends are provided with dosing mouth 7; Main shaft 2 is installed in the cylindrical shell 4 through rack sleeve 1, and main shaft 2 one ends are connected with variable-frequency motor 6, and the other end is connected with spiral administration axle 3; The other end of spiral administration axle 3 is positioned at administration mouth 5, and main shaft 2 is provided with sweeps medicine blade 8.Vertical design make medicinal powder gravity with sweep under the effect of medicine blade 8 to 5 operations of administration mouth, the design of adding the tapered bucket in cylindrical shell 4 bottoms can not cause the residual of medicinal powder.
Described rack sleeve 1 two ends are provided with seal.Can avoid main shaft to be corroded like this by medicinal powder.
Described spiral administration axle 3 is provided with helical blade 9.
Describedly sweep the below that medicine blade 8 is positioned at cylindrical shell 4 cylinders and circular cone boundary line.
Described cylindrical shell 4, spiral administration axle 3, rack sleeve 1 and main shaft 2 materials are stainless steel.
Described administration mouth 5 materials adopt polytetrafluoroethylene (PTFE).Adopt these materials to prolong the service life of administration mouth 5.
During use; Start variable-frequency motor 6; Variable-frequency motor 6 drives main shaft 2 rotation at a high speed in rack sleeve 1, and the medicine blade 8 of sweeping on the main shaft 2 also rotates with the spiral administration axle 3 that is attached thereto thereupon, adds medicinal powder at dosing mouth 7; Under the effect of sweeping medicine blade 8 and gravity; It is broken and drop in the back taper tube of cylindrical shell 4 bottoms that medicinal powder is swept medicine blade 8, and under the effect of the gravity and the helical blade 9 of rotation at a high speed, medicinal powder scatters and falls into and the sewage that fully is dissolved in the full-automatic sewage treating machine foul water tank from administration mouth 5 rounded face.
