Description

Conveying pipe of goaf green filling system

Technical Field

The utility model relates to a conveying pipe of a goaf green filling system, and belongs to the technical field of auxiliary equipment for coal mining.

Background

The amount of the coal slime accumulated in the gangue hill of a certain mine is large, and the amount of the residual flotation tailings (the water content is about 70%) after washing and processing is larger than the amount of the coal slime. If the flotation tailings are discharged to the waste dump for stacking, a large amount of waste dump land resources are occupied, so that the flotation tailings are decided to be used for filling the goaf, and the zero discharge of the flotation tailings is realized, and therefore, a corresponding filling system is required to be designed.

Among them, the delivery tube is one of important devices.

Preferably, a hanging basket is arranged in the bent pipe, a take-up reel is arranged on the outer side wall of the bent pipe, the upper end of the hanging basket is connected with the take-up reel through a rope, one end, far away from the hanging basket, of the rope is fixed with the take-up reel, and a self-locking mechanism and a rocking handle are arranged on the take-up reel.

Preferably, the opening of the branch pipe is fixed with a flange, the upper end surface of one side of the flange is provided with a groove allowing the rope to pass through, the sealing plate is connected with the flange through bolts, and a gasket is arranged between the flange and the sealing plate.

Preferably, the gasket is a rubber gasket.

Preferably, the lower end of the hanging basket is a spherical surface protruding towards the interior of the hanging basket.

Preferably, the number of the straight pipes is more than 2, and two adjacent straight pipes are connected through flanges.

Preferably, the straight pipe is fixedly arranged on the ground or a wall surface through a pipe clamp.

Preferably, a handle is fixed on the sealing plate.

The utility model has the beneficial effects that: compared with the prior art, the utility model is convenient for cleaning dirt on the bent pipe and collecting and pouring out the cleaned dirt blocks.

Detailed Description

The utility model will be further described with reference to the accompanying drawings and specific examples.

Reference numerals in the drawings of the specification include: straight pipe 10, pipe clamp 11, flange 12, return bend 20, branch pipe 21, shrouding 22, handle 23, hanging flower basket 24, rope 25, take-up reel 26, rocking handle 27.

Example 1:

the utility model provides a collecting space area green fills conveyer pipe of system, as shown in fig. 1, including straight tube 10 and return bend 20, return bend 20 is used for connecting two straight tubes 10 and changes the direction of straight tube 10 from the horizontal direction to vertical direction or changes the direction of straight tube 10 from vertical direction to horizontal direction, be connected with branch pipe 21 on the return bend 20, the oral area of branch pipe 21 is fixed with flange 12, the oral area of flange 12 is through bolted connection there being shrouding 22, be provided with the gasket in the middle of flange 12 and shrouding 22, the gasket is the rubber gasket, the upper end of shrouding 22 is fixed with rectangular frame form's handle 23.

As shown in fig. 1, the direction of the straight pipe 10 is changed from the horizontal direction to the vertical direction, a hanging basket 24 is arranged in the bent pipe 20, the lower end of the hanging basket 24 is an upward-protruding spherical surface, a take-up reel 26 is fixed on the outer side wall of the bent pipe 20, the upper end of the hanging basket 24 is fixedly connected with a rope 25, the rope 25 is a steel wire rope, one end of the rope 25 far away from the hanging basket 24 is fixed with the take-up reel 26 after passing through the upper end of the flange 12 of the opening of the branch pipe 21, a groove allowing the rope 25 to pass through is formed in the right end surface of the opening of the flange 12, a self-locking mechanism and a rocking handle 27 are arranged on the take-up reel 26, the self-locking mechanism and the rocking handle 27 are of the existing structure, and the principle of the take-up reel 26 is similar to that of a manual lifting clothes hanger.

As shown in fig. 1-2, during the use of the pipeline, the winding drum 26 is utilized to wind up the hanging basket 24 into the branch pipe 21, so that the hanging basket 24 is prevented from blocking the movement of fluid; when the dirt inside the elbow pipe 20 needs to be cleaned, paying off by utilizing the take-up reel 26, lowering the hanging basket 24 to the lower end of the elbow pipe 20 and limiting the lower end of the elbow pipe 20, and in the process of cleaning the elbow pipe 20 through the branch pipe 21, the dirt inside the pipeline falls into the hanging basket 24 to be collected, after the cleaning is finished, pulling the hanging basket 24 into the branch pipe 21 by utilizing the take-up reel 26 again, taking out the hanging basket 24, pouring out the dirt blocks inside, and then putting the hanging basket 24 into the elbow pipe 20.

As shown in fig. 1, in the bent pipe 20 in which the direction of the straight pipe 10 is changed from the vertical direction to the horizontal direction, the branch pipe 21 is disposed downward, so that the basket 24 is not required.

In this embodiment, the number of the straight pipes 10 is set to be more than 2, a specific number is selected according to actual requirements, two adjacent straight pipes 10 are also connected through a flange 12, as shown in fig. 1, and the straight pipes 10 are fixedly installed on the ground or a wall surface through pipe clamps 11.

The foregoing is merely illustrative of the present utility model, and the scope of the present utility model is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the scope of the present utility model, and therefore, the scope of the present utility model shall be defined by the scope of the appended claims.
