Description
Technical Field
The utility model relates to a mud removing device in a sedimentation tank adopting a submerged slurry pump, belonging to a mud water treatment system.
Background
In the excavation construction of tunnels for constructing subways and the like, large-granularity sand and stone and coarse-grained slurry discharged by a shield machine are firstly classified and separated by a vibrating screen and a cyclone and are dewatered and transported away, the slurry with the granularity smaller than 20 microns needs to be naturally precipitated and separated by a special facility, namely a slurry sedimentation tank, the fine-grained slurry at the upper part is conveyed to the shield machine to be used as a lubricant for recycling, and sediments with larger specific gravity and coarser granularity at the lower part need to be continuously removed and discharged. The conventional method for removing the sediment in the sedimentation tank is to excavate with an excavator, as shown in fig. 1, reference numeral 101 is an excavator for excavating the sediment; reference numeral 102 is a mud sedimentation tank; reference numeral 103 is slurry in the settling tank; reference numeral 104 is a passage around the settling pond for the excavator to walk and work. This conventional method of removing sludge has the following significant disadvantages: 1. an excavator needs to be equipped, so that the equipment investment is large; 2. slurry is fished from the lower part of the sedimentation tank by an excavator, so that the operation efficiency is low; 3. the water content of the slurry dug by the excavator is very high, so that the slurry cannot be directly transported, and the water content of the slurry is reduced by taking up a place for airing or adding dry quicklime, fly ash and the like, so that the occupied area and the treatment cost are increased; 4. a dedicated road of sufficient width and hardness needs to be constructed for the excavator, increasing site occupation and construction cost.
SUMMERY OF THE UTILITY MODEL
According to one aspect of the present invention, there is provided a slurry discharge apparatus in a settling tank using a submerged slurry pump, characterized by comprising:
a guide rail erected on the top of the sedimentation tank;

Detailed Description
The utility model provides a device and a method for removing mud in a sedimentation tank by adopting an underwater slurry pump, aiming at the defects of the traditional method for removing sediments, and the device and the method are used for replacing the original method for excavating mud by an excavator. A mud discharging apparatus in a settling tank using an underwater slurry pump according to an embodiment of the present invention is shown in fig. 2, in which reference numeral 201 denotes an underwater slurry pump for sucking coarse-grained mud settled in a lower portion of the settling tank; reference numeral 202 is a movable carriage on which the submerged slurry pump 201 is mounted; reference numeral 203 is a guide rail which is erected at the top of the sedimentation tank and used for the travelling of the travelling trolley; reference numeral 204 is a passage for people to walk around the sedimentation tank; reference numeral 205 is a slurry in the settling tank; reference numeral 206 is a sedimentation tank; reference numeral 207 is a hand-drive block support fixed to the traveling carriage 202; reference numeral 209 is a manual hoist for hoisting the slurry pump, and the manual hoist 209 is hung on the bracket 207; reference numeral 208 is a hoisting wire rope; the reference number 210 is a hanger of the submerged slurry pump, the upper end is connected with a hoisting steel cable 208, and the lower end is connected to the base of the submerged slurry pump; reference numeral 211 is a slurry feed hose. When the submerged slurry pump 201 does not work, the submerged slurry pump 201 is lifted up through the hand hoist 209, the lifting steel wire 208 and the lifting frame 210, sticky slurry at the lower part of the sedimentation tank is separated, and the influence on the next operation caused by slurry silting is prevented.
The working process of the method for removing the mud in the sedimentation tank by using the submerged slurry pump according to the utility model is that the submerged slurry pump 201 is driven to move along the length direction of the sedimentation tank by pushing the moving trolley 202 (for example, manually) so as to conveniently extract the precipitated mud at each part in the sedimentation tank 206, the extracted mud is conveyed into a mud storage tank of a filter press of a mud and water treatment system through the mud conveying hose 211 and is fed into the filter press for final dehydration treatment, and the mud is discharged after forming a mud cake.
Compared with the traditional method, the sedimentation tank mud removal method and the sedimentation tank mud removal device at least have the following 4 advantages:
1. the equipment investment is small;
2. the operation is convenient, and the slurry is extracted timely and quickly;
3. an excavator channel and a mud airing field are not needed, and the field occupation is greatly reduced;
4. and quick lime or fly ash does not need to be added into the dug slurry, so that the slurry treatment cost is saved, and the pollution to a construction site and the environment is avoided.
