DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application. ​​

[0038] Embodiment:

[0039] As Figures 1-6 shown, the tubular tool for assisting mine filling slurry stope dehydration provided by the embodiment comprises an inner tube 100, an outer tube 400 and a filter screen 600, wherein:

[0040] The inner tube 100 is provided with a plurality of through holes 110 on the tube wall, so that water enters the inner tube 100. The inner tube 100 is provided with a connecting structure at both ends, and the connecting structure is used for connecting a plug 200 or a pipe joint 300. When the two ends of the inner tube 100 are connected to the pipe joint 300, a plurality of different inner tubes 100 can be spliced to extend the length of the tubular tool for assisting mine filling slurry stope dehydration. When one end of the inner tube 100 is connected to the pipe joint 300 and the other end is connected to the plug 200, the plug 200 can plug the end of the inner tube 100, and the connected pipe joint 300 can be used to splice the remaining inner tubes 100 or connect a negative pressure generating device. It should be noted that the negative pressure generating device can be a water pump, so as to generate negative pressure in the inner tube 100, so that water is more easily sucked into the inner tube 100.

[0041] The outer tube 400 is sleeved outside the inner tube 100 and locked by a locking assembly. The outer tube 400 is provided with a plurality of water inlet holes 420, and the plurality of water inlet holes 420 correspond one-to-one with the plurality of through holes 110. The filter screen 600 is arranged between the inner tube 100 and the outer tube 400, and the filter screen 600 is used to block large particles from entering the through holes 110.

[0042] In use, the plug 200 can be connected to one end of the inner tube 100, so as to plug the one end of the inner tube 100 by the plug 200, thereby avoiding air leakage. At the same time, the pipe joint 300 is connected to the other end of the inner tube 100, and then the negative pressure generating device is connected through the pipe joint 300. In this case, the tubular tool can be directly inserted into the mine filling slurry, and the plug 200 needs to be deep into the slurry. Alternatively, the pipe joint 300 can be connected to both ends of the inner tube 100, and in this case, the inner tube 100 can be used for splicing to extend the length of the tubular tool. In both of the above cases, the tubular tool is inserted into the mine filling slurry, and the water in the slurry enters the inner tube 100 through the water inlet holes 420, the filter screen 600 and the through holes 110 in turn. With the aid of the negative pressure generating device, the water in the inner tube 100 can be further accelerated and pumped out. The filter screen 600 can prevent particles in the slurry from entering the inner tube 100, thereby reducing the probability of pipe blockage of the inner tube 100.

[0043] Through the above structure, the tubular tool for assisting mine filling slurry stope dehydration provided by the embodiment can be used to remove water in the mine filling slurry by suction, has a high dehydration rate, can be applied to mine filling slurries of any concentration, thereby accelerating the drying and solidification efficiency of the slurry, and has the advantages of simple structure, low manufacturing and using costs, convenient carrying, flexible use, repeated use, and practicality.

The water inlet hole 420 corresponds to the through hole 110, so that water can pass through the water inlet hole 420 and the through hole 110 into the inner layer pipe 100.

The two nuts 520 are screwed on the screw rod 510, and the two nuts 520 are located on the two sides of the outer layer pipe 400, respectively, and the two nuts 520 press the two half pipes 410 of the outer layer pipe 400 against the filter screen 600. When the nuts 520 are tightened, the locking assembly is locked, and when the nuts 520 are loosened and removed, the locking assembly is unlocked.

[0050] An optional implementation of the embodiment is as follows: the plug 200 comprises a connecting block 210 and a sharp head 220 arranged at one end of the connecting block 210, the connecting block 210 is provided with a counterbore 211, and an internal thread 212 for screwing with the external thread 120 is arranged on the hole wall of the counterbore 211, thereby facilitating the connection of the plug 200 to the end of the inner layer pipe 100 and the plugging of the end pipe opening of the inner layer pipe 100. The sharp head 220 is located outside the inner layer pipe 100, so as to smoothly insert the tubular tool into the mine filling slurry.

[0051] An optional implementation of the embodiment is as follows: the filter screen 600 is a stainless steel screen, and the mesh number of the stainless steel screen is 500 meshes, thereby prolonging the service life of the filter screen 600 and better blocking particles from entering the through holes 110 of the inner layer pipe 100.
