Abstract

The utility model provides a screw feeding device comprising a motor, impellers and a vertical shaft. A rotating shaft of the motor is connected with the vertical shaft which is connected with a plurality of groups of impellers. Each group of impellers consists of two blades which are symmetrical with each other and vertical to the vertical shaft. The groups of impellers are sequentially arranged from top to bottom and vertical to in sequence. The screw feeding device has the advantage that mud entering a hopper is forced to enter a conveying screw of a screw pump under the rotary pushing and pressing action of screw impellers. The diameters of feeding screw impellers are gradually and sequentially reduced so that the mud entering the hopper suffers continuous downward pressure and constantly enters the conveying screw of the screw pump, thereby realizing continuous and stable feeding of a system. The feeding screw impellers and the motor share one shaft, and the motor is of variable frequency control and controls the rotational speed of the screw impellers by means of a frequency converter, thereby adjusting the pushing and pressing force of the impellers and ensuring the stable feeding of the system. The feeding screw impellers can cut the mud, thereby reducing the viscosity of the fed mud and being favorable for successful mud conveyance.

Description

A kind of screw feeding device
Technical field
The utility model relates to a kind of screw feeding device, particularly a kind of screw feeding device that is used for sewage treatment works's dewatered sludge.
Background technique
By the end of the year 2008,1442 of sewage treatment workss have been built up in the whole nation, sewage treatment capacity reached for 8500 ten thousand stere/days, when sewage obtains handling, produce a large amount of mud, pollutants in sewage matter major part is transferred in the mud, if can not properly dispose, can cause serious secondary pollution to environment.Along with the gradually attention of people to sludge treatment, increasing sludge disposal technology is rapidly developed, and mainly contains sludge composting, mud landfill, sludge incineration, sludge drying and mud carbonization.
The charging of existing sludge disposal technology mostly is the mud extraction of Haug drainer room greatly, owing in dehydration, need to add flocculating agent, contain a large amount of microbial cells in the mud simultaneously, make that the combination degree of internal water in the mud, adsorbed water, capillary water and mud granule is very high, be difficult to slough fully with mechanical means, moisture content is still at 75%-85%.When carrying out sludge treatment, enter the conveying screw top that the mud system is generally screw pump and be installed into hopper, after mud adds feeding funnel to, by not having the axle helical feed to follow-up sludge treatment unit.Because mud has very high viscosity and elasticity, cause when advancing mud, occurring easily building bridge, can not make mud continuous enter conveying screw, also just can not guarantee charging continuously and the stablizing of flow.This also directly causes the instability of follow-up sludge treatment system operation.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the utility model is a kind of improvement to the traditional sludge feed system, purpose is the rotation pushing effect by helical runner, make mud force to enter the conveying screw of screw pump, guarantee the continuity and the stability of sludge treatment system feeding, and then guarantee the stable operation of whole sludge treatment system.
For achieving the above object, technical solution of the present utility model provides a kind of screw feeding device, wherein: this device includes motor, impeller, vertical shaft, on the running shaft of described motor, be connected with vertical shaft, on vertical shaft, be connected with many group impellers, every group of impeller is made of symmetrical two blades perpendicular to vertical shaft, organizes the vertical mutually successively from top to bottom setting of impeller more.
Two blade edges and the blade substantially horizontal of described impeller are 30 °-45.
The diameter of described many group impellers reduces from top to bottom successively.
Effect of the present utility model is to enter mud in the hopper under the rotation pushing effect of helical runner, forces to enter the conveying screw of screw pump.The feed auger impeller is installed on the axle vertical with the screw pump feed auger, have three groups from top to bottom, impeller diameter reduces successively, makes the mud that enters hopper be subjected to continuous down pressure, enter the conveying screw of screw pump continuously, realize the continous-stable charging of system.The power plant of feed auger impeller are motor driving, and motor is coaxial with helical runner, and motor is a VFC, and by the rotating speed of Frequency Converter Control helical runner, thereby the pushing force of adjustment impeller guarantees the stable charging of system.The feed auger impeller has dissection to mud, has reduced the viscosity of charging mud, helps the smooth delivery of power of mud.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated screw feeding device structure of the present utility model and using process.
Screw feeding device of the present utility model, this device includes motor 1, impeller 2, vertical shaft 3, on the running shaft of described motor 1, be connected with vertical shaft 3, on vertical shaft 3, be connected with many group impellers 2, every group of impeller 2 is made of symmetrical two blades perpendicular to vertical shaft 3, many group impellers 2 are vertical mutually successively from top to bottom to be provided with, and the diameter of described many group impellers 2 reduces from top to bottom successively.
Two blade edges and the blade substantially horizontal of described impeller 2 are 30 °-45.
Screw feeding device of the present utility model is achieved in that
As shown in Figure 1, 2, screw feeding device is driven by motor 1, and the charging advancing means is made up of three groups of helical runners 2 and a vertical shaft 3.When the motion of spinning from top to bottom of impeller many group impellers 2 under the drive of motor 1, material is formed continue downward active force, material continuously enters the conveying screw of screw pump, the forced conveyance of realization material.
Fig. 3 is an embodiment example of the present utility model.Impeller 2 with vertical shaft 3 motion of spinning, after dewatered sludge enters hopper 4, under the continuous rotary pressure of three groups of impellers 2, forces to enter the conveying screw 5 of screw pump 6 under the drive of motor 1, enter follow-up sludge treating system.
