Description

Technical Field

[0001] The utility model relates to the technical field of pulping devices, and specifically relates to a pulping device for coal mine backfilling. Background Art

[0002] Coal mine backfilling is a process of using filling materials to fill the space generated after coal mine exploitation to maintain geological stability and prevent ground subsidence. In this process, a pulping device is responsible for mixing solid backfilling materials (such as tailings, fly ash, etc.) with water to form a slurry-like object, and then transporting it to the cavity of the mine;

[0003] In order to meet the large-scale demand for coal mine backfilling, existing pulping devices are usually relatively large, including a large pulping tank and stirring paddles. The main function of the stirring paddles is to mix solid backfilling materials and water in the pulping tank to form a uniform slurry-like object;

[0004] However, such large pulping devices have some significant problems. Firstly, due to the large volume of their stirring paddles, subsequent cleaning and maintenance work (because the slurry will continuously adhere to the stirring paddles, resulting in an increase in the weight of the stirring paddles or damage due to stirring) is complex and time-consuming. This not only affects the normal operation of the pulping device but also reduces production efficiency. In addition, the operation of large pulping devices usually requires more energy, and due to their complex structure, the failure rate is relatively high, which all increases the operation cost.

A motor 301 is fixedly connected to the pulping tank 100. The motor 301 is power-connected to the driving sprocket 302. In this way, by driving the driving sprocket 302 to rotate by the motor 301, the chain 304 can be made to traction the sliding mounting table 200 to perform a linear motion on the sliding port 101, so as to achieve the required effect of the device. At the same time, in order to seal the pulping tank 100, telescopic folding plates 305 are fixedly connected between the two sliding mounting tables 200 and between the sliding mounting table 200 and the end of the sliding port 101.

[0032] In summary, this embodiment discloses a pulping device for coal mine backfilling, which is mainly used for preparing a large amount of coal mine backfilling slurry. Specifically, the required raw materials can be put into the pulping tank 100 through the feeding port, and water can be injected through the water inlet pipe in proportion. Then, the motor 301 works to drive the sliding mounting table 200 to slide linearly on the sliding port 101. During the linear sliding of the sliding mounting table 200, the gear 403 can rotate under the action of the rack 107. After the gear 403 transmits the power to the worm 404, the worm 404 drives the worm wheel 405 to rotate, and then the stirring paddle 401 rotates to stir the raw materials in the pulping tank 100. When the stirring is completed, the slurry can be discharged from the slurry outlet pipe 103 by opening the valve 104;

[0033] When it is necessary to clean the solids attached to the surface of the stirring paddle 401, the mounting machine table 202 and the stirring paddle can be removed from the pulping tank 100 by unscrewing the bolts.
