Problems solved by technology

[0005] (1) The pulping efficiency of clay raw pulp is low, and the pulping volume of soaking and stirring pulping method is not more than 1500m per month 3 , the clay pulping machine pulping method monthly pulp production is not more than 3500m3 3 , unable to meet the needs of larger-scale grouting projects; (2) The number of workers used in the clay pulp making process is relatively large, and the number of workers in the soaking and stirring method is 7 to 9 per shift. The number of workers is 5-6 per shift, and the construction cost is very high; (3) The pulping method of the clay pulper has higher requirements for the undisturbed clay, and the sand content is not more than 3%, otherwise, the wear and tear on the equipment will be greater, Seriously affect the service life of the clay pulping machine, therefore, the range of clay materials is small; (4) The pulping process of clay raw pulp is relatively complicated, the waste of raw materials caused by man-made is serious, and the maintenance rate of equipment is high. Repair once a day, resulting in increased pulping costs
(5) The undisturbed clay has high requirements for transportation and stacking, takes up a lot of space, and has poor social benefits

Abstract

The invention discloses a device for quickly and efficiently preparing clay primary pulp and a pulping process. The device for quickly and efficiently preparing clay primary pulp comprises a clay pulp preparing mechanism, a clay pulp precipitating and impurity-removing mechanism, a clay pulp homogenizing mechanism and a clay primary pulp storage mechanism; the clay pulp preparing mechanism comprises a clay stacking mechanism, a mud pump and a high-pressure spray nozzle for pulping; a liquid outlet end of the mud pump is in fluidic conduction connection with a liquid inlet end of the high-pressure spray nozzle for pulping; a liquid outlet end of the high-pressure spray nozzle for pulping is arranged in the clay stacking mechanism; a liquid outlet end of the clay stacking mechanism is in fluidic conduction connection with a liquid inlet end of the clay pulp precipitating and impurity-removing mechanism; a liquid outlet end of the clay pulp precipitating and impurity-removing mechanism is in fluidic conduction connection with a liquid inlet of the clay pulp homogenizing mechanism; and a liquid outlet end of the clay pulp homogenizing mechanism is in fluidic conduction connection with a liquid inlet end of the clay primary pulp storage mechanism. The device for quickly and efficiently preparing clay primary pulp can improve production efficiency of a conventional clay primary pulp pulping process, reduces pulping cost and ensures pulping quality of the clay primary pulp.

Description

technical field [0001] The invention relates to the field of ground pre-grouting, in particular to a device and a pulping process for rapidly and efficiently preparing clay raw slurry. Background technique [0002] Ground pre-grouting technology is an important method of water prevention and stratum reinforcement in mines. It refers to using a drilling rig to drill grouting holes around the shaft or in the target layer from the ground before the shaft is excavated or the working face is advanced. Belt for grouting. Comprehensive grouting technology is a comprehensive technology with advanced technology and wide application in the current ground pre-grouting. It has been successfully applied in the construction process of hundreds of coal mines and non-coal mines. [0003] However, with the continuous expansion of the mining scale, the depth of the shaft is getting deeper and deeper. Regardless of coal mines or non-coal mines, the hydrogeological conditions in deep strata ar...
