Series connection process device for freezing pipes of pitshaft of overlength inclined shaft

Abstract

The invention discloses a series connection process device for freezing pipes of a pitshaft of an overlength inclined shaft, and relates to a process device for freezing pipes of a pitshaft of an inclined shaft. According to the device, 5 rows of freezing pipes are arranged on the ground of the pitshaft of the overlength inclined shaft longitudinally, a plurality of freezing pipes are arranged on the ground of the pitshaft of the overlength inclined shaft laterally, and a liquid inlet pipe and a liquid outlet pipe are arranged in each freezing pipe; each freezing hole is divided into sections I, II, III, IV and IV along the horizontal direction, and each section is provided with a saline inlet header pipe and a saline return header pipe; the sections I, II and III are connected in series by using the three freezing pipes; a liquid inlet pipe of a first freezing pipe is connected with the saline inlet header pipes, and a liquid outlet pipe of the first freezing pipe is connected with a liquid inlet pipe of a second freezing hole; a liquid outlet pipe of a second freezing pipe is connected with a liquid inlet pipe of a third freezing pipe; a liquid outlet pipe of the third freezing pipe is connected with the saline return header pipes; and the sections V and VI are connected in series by using the two freezing pipes, and the saline inlet header pipe and the saline return header pipe of each section are connected with a water pump. The series connection process device has the advantages that: the total circulating amount of saline is reduced, the power consumption of a system is reduced, and the series connection process device is easy to install.

Description

technical field [0001] The invention relates to a process device for freezing pipes in inclined shafts, in particular to a series device for freezing pipes in super-long inclined shafts [0002] art installation. Background technique [0003] Since entering the 21st century, my country's coal production and construction has ushered in a new upsurge. Especially in recent years, mines in western my country have developed in depth, and the production capacity of mines has gradually increased. The mixed development method of inclined shafts has been widely used. Generally, three shafts are arranged, namely, the main inclined shaft, the auxiliary shaft and the wind shaft. In view of the characteristics of Cretaceous soft rock formations (low strength and high water content) in Inner Mongolia and other western regions, the shafts of newly built mines are basically constructed by the freezing method. [0004] my country's vertical shaft freezing and sinking technology has become ...
