Key technologies and objectives
Key technologies
1.Slime water containing the thickness of the particle mixing, pumping and conveying technology:
MQ-1 type slime dredging conveyor: the machine innovation previous design, the removal of stir Sump slime slime, slime conveying set integrated automatic dredging machine, the machine free to move, the highly aggregated mixing and pumping and pumping equipment can swing around, move up and down to different heights, the different orientation slime stirring pumping. The level of transmission distance up to 1200 meters), the slime conveying a concentration of 50%, the operator need only one person to achieve a the water positions slime in the real sense of the Qing automatically dig conveying. Its key technologies: automatic mixing slime water, automatic filter debris, stirring collection and pumping height, stirring pumping full range of work, long-distance transmission of high concentration slurry.
Thickness slime separation, neither affect the use of the filter press, they can not Paste screen
Patent development and design of new products "MC-1 type of coarse slime extension": It is specifically for the complex nature of slime, designed to provide continuous and efficient filter press quality to be separated slime slime separation equipment, main The aim will be not easy to press dewatering slime coarse first isolated from Slime, which can improve the quality of the coal slurry dewatering, but also greatly enhance the efficiency of coal sludge dewatering. The key technology is the thickness of the slime separation of coarse slime automatically loading all fine slime able to enter the filter press equipment.
Efficient dehydration. Coal washing mud
Development and design of new "ZQ-4 type high efficiency continuous pressure filter": Based on the slime dewatering treatment of in-depth research and a summary of the many years of experience, we will develop new efficient continuous filter press, the aircraft breaking the traditional filter press filter theory , under the same conditions in the size of the equipment, a substantial increase in unit production of slime. Key technologies: filter press hydraulic control, dual work area, both ends of the feed, automatic loading.
Overall goal
Nantun Coal Mine thickness slime mixed new Sump developed automatically cleared digging process and system equipment, automatic cleanup of various properties of slime, automatic separation, automatic loading transport, solve Clearance labor intensity, insecurity, low efficiency, Problems of pollution roadway. Promote the construction of coal modern mine slime dug civilized production and production safety.
Overall technical program:
1) The equipment consists of: the water position dredging system was stirred by the slime equipment, slime conveying equipment, buffer mixing vessel, the slime separation equipment (loading conveyor belt) four major components.
2) The process route:
Sump slime impact of high-pressure water, stirring, broken ----> slime clear dug pumping ----> slime the rough segmentation (separation of coarse slime loading) ----> buffer mixing container, stir ----> double-acting, separation filter press dewatering ----> belt conveyor loading automatically.
Process is as follows:
The Sump slime by high pressure water impact stir reaches a certain concentration of large particles are crushed with slime pump transportation to the water hatch slime crude extension within, will be greater than 0.3mm or more coarse slime separation Firstautomatically loaded mine car. The remaining slime water from entering the buffer container, the buffer containers to store a certain amount slime dewatering filter press in order to ensure that there is always a sufficient supply of slime. Due to slime sedimentation fast, so must add stir agencies keep stirring to prevent precipitation. The dehydrating filter press will buffer the stirring tank of the slime is conveyed to a certain pressure into the filter press chamber, the slime dehydration. Prolapse of the slime through the filter press the lower part of the conveyor belt loading automatically or sent to another belt away, prolapse of the water back to another water storage impoundments. Slurry the clean-up process is complete.

Economic and social benefits analysis
1. Sump slime (silt) belongs to the mechanized cleaning of coal production waste, slime and dehydration treatment to resolve coal slurry pollution transport on the roadway, is conducive to underground environmental improvement.
2. Slime (silt) after dehydration treatment, its calorific value is close to the raw coal can be used as raw coal sales. Waste recycling, economic and social benefits significantly. According to estimates: Sump dehydration of slime can be achieved revenue of over 100 million.
3. Sump is a high risk of workplace mechanization and automation clean water positions, and solve the security problems of the clearance operations.
4. Automatic dredging system to clean up the slime fast, good quality. Increased 2-5 times more efficient than manual cleaning, clearance cost savings of 15-20 million each time.
5. Water sump clean-up time is shortened to improve the margin of safety of coal mine water and flood control.
6. The role of science and technology:
And automatically cleared dig the successful application of the system, will promote the modernization and standardization of the coal mine construction. Coal as the main source of energy in our country, the country is focusing on the construction of large coal bases, major mining process has been close to the international level, Sump cleaning, however, is still in use artificially low efficiency, consuming a lot of human and material resources, does not meet the needs of the modern mine construction . Its successful application is bound to promote the modernization of these mines, less mention efficiency, reduce labor intensity, improve the overall technological level of coal mine.
