Description

Technical Field

[0001] The present invention relates to the technical field of subway tunnels, and in particular to a slag processing device and an operating method thereof. Background Art

[0002] During the shield construction process of subway tunnels, a large amount of mud and water mixture will be produced. These mixtures contain hard objects such as gravel and stones. For subsequent construction and environmental protection, these slag soils need to be effectively treated. In the traditional treatment method, the hard objects in the mixture need to be filtered through a filter net first, and then the filtered mud and water are separated. In the traditional slag treatment device, each step is often carried out independently during the treatment process, that is, one step can only be carried out after the next step is completed. This step-by-step treatment method not only makes the entire treatment process lengthy, but also reduces the efficiency of the device in treating slag soil. Especially in an environment such as subway tunnel shield construction that requires efficient and continuous operation, the traditional slag treatment device obviously cannot meet actual needs.

The push rod device is activated, causing the front door panel of the filter plate replacement assembly to move forward, opening the top of the filter bin. The soil-soil mixture falls onto the filter plates for initial separation, leaving larger stones and impurities on the filter plates. Simultaneously, the squeezing assembly on the active movable frame moves with the active movable frame, squeezing the storage bag. The water and soil in the bag are quickly separated under the squeezing action, with the water flowing into the water storage bin and the soil remaining in the bag. S2. Replace the filter plate and clear the larger stones and impurities in the filter bin: push the active movable frame to move horizontally on the supporting outer frame through the push rod device. The movement of the active movable frame drives the filter plate replacement assembly to move. The filter plate replacement assembly pushes the passive movable frame to move the front door panel out of the filter bin; as the front panel moves away, the filter plate slides down along the inner inclined plate provided on the supporting outer frame into the filter bin, completing the replacement of the filter plate.

[0015] Furthermore, the squeezing active component enables the soil and water in the storage bag to be separated quickly under the squeezing action, thereby improving the separation efficiency. The cooperation of the guide block and the guide groove ensures the stability and accuracy of the squeezing process. Furthermore, the filter plate replacement assembly makes the filter plate replacement process simpler and faster, reducing replacement time and labor costs. At the same time, the filter plate replacement assembly can automatically drop and separate the stones, further improving the efficiency of soil treatment.

[0016] Furthermore, the push rod device enables the active movable frame to move horizontally on the supporting outer frame stably, thereby driving the filter plate replacement assembly and the extrusion movable assembly to work. The combination of the hydraulic push rod and the push rod frame improves the stability and reliability of the entire device.

[0017] Furthermore, the combined use of multiple filter plates increases the flexibility and adaptability of the device, and the device can be adjusted and replaced according to actual needs.

[0018] Furthermore, the hydraulic push rod drives the front door panel to move, allowing the filter plate to be easily removed and replaced, further simplifying the replacement process. At the same time, the design of the inner inclined plate allows the filter plate to slide smoothly into the filter chamber, eliminating the tedious manual handling.

[0019] Furthermore, the passive movable frame enables it to work in conjunction with the active movable frame to achieve automatic falling and separation of stones; the combined use of the L-shaped movable plate and the U-shaped movable plate increases the stability and reliability of the device, ensuring the smooth progress of work.

[0020] Furthermore, the pressure pump enables the mixture to be effectively introduced into the storage bag, which facilitates the subsequent extrusion and separation process.
