preparation example Construction

[0044] The present invention also provides a paste material preparation method of the above-mentioned spiral continuous stirring device for paste materials, the method comprising the following steps:

[0045] Step 1: Assemble the spiral continuous mixing device for the paste material and place it in the goaf treatment area, separation layer treatment site or water interception curtain construction position.

[0046] Step 2: Through the crushing equipment, materials such as building solids, coal gangue, pebbles and gravels are crushed into fine aggregates of 0-10 mm, which are used to prepare paste materials.

[0047] Step 3: Transfer fine aggregates such as sand or crushed construction solids, coal gangue, pebbles and gravels to the receiving hopper 12 of the conveying device by an excavator or a forklift, and the transmission roller shaft 18 drives the conveyor belt 11 to drive, and the conveyor belt 11 Send fine aggregates such as sand or broken building solids, coal gangue,...

Embodiment 1

[0054] Step 1: Assemble the conveying device, stirring device and pumping device into a set of spiral continuous stirring device for paste material, and place the device on the site of the gob treatment project.

[0055] Step 2: Through the crushing equipment, the construction waste solid waste materials are crushed into fine aggregates with an average particle size of 5mm, which are used to prepare paste materials.

[0056] Step 3: Transfer the construction waste solid waste material fine aggregate with an average particle size of 5 mm to the receiving hopper 12 by a forklift, and the transmission roller shaft 18 drives the conveyor belt 11 to drive, and the conveyor belt 11 solidifies the construction waste with an average particle size of 5 mm. The waste material fines are conveyed to the mixer 6 .

[0057] Step 4: Prepare cement at the pulping station: fly ash with 3:7 and water-cement ratio of 1:1, transport the slurry to the mixer 6 through the slurry delivery pipe, and ...

Embodiment 2

[0065] Step 1: Assemble the conveying device, stirring device and pumping device into a set of spiral continuous stirring device for paste material, and place the device on the site of the gob treatment project.

[0066] Step 2: Screen the medium sand as the fine aggregate of the paste material for the preparation of the paste material.

[0067] Step 3: The medium sand is transferred to the receiving hopper 12 by a forklift, the transmission roller shaft 18 drives the conveyor belt 11 to drive, and the conveyor belt 11 transports the medium sand to the mixer 6 .

[0068] Step 4: Prepare cement at the pulping station: fly ash is 3:7, and the slurry with a water-cement ratio of 1:1 is transported to the mixer 6 through the slurry delivery pipe, and enters the mixer 6 and 80% through the slurry delivery hole 7 The amount of medium sand is mixed to preliminarily prepare a paste material, and the preliminarily formed paste material falls into the barrel 1 of the stirring device.

Abstract

The invention relates to a spiral continuous stirring device for paste filling material and a paste material preparation method. The device at least comprises a cylinder body, a support, a stirring device, a conveying device and a pumping device; the cylinder body is erected at the upper part of the support, and the cylinder body is of a U-shaped structure and is used for containing the paste material and used as a carrier for stirring, cutting and conveying the paste material; a mixer is connected with the upper portion of the front end of the cylinder body, a discharging port for dischargingis formed in the lower portion of the tail end of the cylinder body, and the stirring device is arranged on the cylinder body to stir, cut and convey the paste materials; the conveying device is arranged on one side of the cylinder body to convey the materials needing to be stirred to the mixer above the cylinder body; and the pumping device is arranged below the discharge port so as to pump materials into a filling drill hole. Therefore, the problems of small sand carrying capacity, low conveying efficiency, non-uniform mixing of the slurry and the sand and unstable material performance of the slurry can be effectively solved, and the performance of the filling material is improved while the sand carrying capacity and the conveying efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of underground engineering filling, reinforcement and water retention, such as mine goaf foundation filling treatment, separation layer zone grouting filling, mine water cut-off curtain, etc., and particularly relates to a paste filling material spiral continuous stirring device and paste Material preparation method. Background technique [0002] Coal is the main energy source in our country. While ensuring the national energy supply, a coal mining subsidence area of ​​about 2 million hectares has been formed during the mining process, and it is increasing at a rate of about 70,000 hectares per year. According to the existing scale of coal mining, it is estimated that the coal mining subsidence area will reach 2.8 million hectares by 2030. my country's coal mining subsidence areas are widely distributed, and problems such as surface subsidence, ground fissures, damage to buildings (structures), and deterior...
