Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine filling technology and relates to an overflow ash-blocking device for filling plate walls. Background Technology
[0002] During mine backfilling, to ensure the backfill material effectively supports the roof and improves the roof connection rate, it is usually necessary to control the separation of moisture and ash in the backfill material. The technical drawback of traditional mine backfilling methods is that it is difficult to effectively separate moisture and ash in the backfill material, leading to a large accumulation of moisture at the top of the backfill material, affecting the consolidation effect and thus reducing the roof connection rate. Furthermore, although overflow pipes can drain excess moisture, they often carry away some ash and cement particles, thus affecting the backfilling quality. Utility Model Content
[0003] The purpose of this utility model is to address the problems existing in the prior art by providing an overflow ash-blocking device for filling plate walls. This device solves the problem in traditional mine filling methods where the moisture and ash in the filling material are difficult to separate effectively, leading to the accumulation of a large amount of moisture at the top of the filling body, which affects the consolidation effect of the filling body and thus reduces the filling top connection rate.
[0004] Therefore, the present invention adopts the following technical solution:
[0005] An overflow ash-prevention device for a filling panel wall includes a panel body, which is vertically arranged and has a first signal pipe, a second signal pipe, an overflow pipe, an exhaust pipe and a filling pipe that are vertically connected to it; wherein: one end of the overflow pipe is provided with a filter screen assembly, which is connected to the overflow pipe by a binding wire; one end of the filling pipe is provided with a flow guide valve.
[0006] Furthermore, the filter assembly includes a connecting ring, with a filter screen disposed in the center of the connecting ring.
[0007] Furthermore, the first signal tube, the second signal tube, the overflow tube, the exhaust tube, and the filling tube are arranged sequentially in the horizontal direction.
[0008] Furthermore, the first signal tube is located above the second signal tube.
[0009] Furthermore, the flow guide valve and the filter assembly are located on both sides of the plate.
[0010] Furthermore, the filter screen pore size is 0.07~0.08mm.
[0011] The beneficial effects of this utility model are as follows:
[0012] During use, this invention can effectively separate moisture and ash, preventing water accumulation at the top of the filling body, reducing the loss of ash and cement particles, and improving the quality of the filling body. In addition, the filling body of this invention has a good consolidation effect, reducing the risk of roof collapse and extending the service life of the filling body. At the same time, it can also reduce the waste of ash and cement particles during the filling process, which is beneficial to environmental protection. Attached Figure Description
[0013] Figure 1 This is a three-dimensional structural diagram of the present invention;
[0014] Figure 2 This is a partial enlarged view of the filter assembly in this utility model.
[0015] In the diagram, 1-plate, 2-first signal tube, 3-second signal tube, 4-overflow tube, 5-exhaust tube, 6-filling tube, 6a-guide valve, 7-filter assembly, 7a-connecting ring, 7b-filter, 8-binding wire. Detailed Implementation
[0016] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.
[0017] like Figure 1 As shown, an overflow ash-blocking device for a filling wall panel includes a panel 1, which is vertically arranged and has a first signal pipe 2, a second signal pipe 3, an overflow pipe 4, an exhaust pipe 5 and a filling pipe 6 connected to it vertically. One end of the filling pipe 6 is provided with a guide valve 6a.
[0018] One end of the overflow pipe 4 is provided with a filter assembly 7, which is connected to the overflow pipe 4 by a tie wire 8. The tie wire 8 is used to fix the filter assembly 7 to the inner end of the overflow pipe 4 to ensure its stable operation during the filling process. The flow guide valve 6a and the filter assembly 7 are located on both sides of the plate 1.
[0019] like Figure 2 As shown, the filter assembly 7 includes a connecting ring 7a, and a filter 7b is provided in the middle of the connecting ring 7a. The filter 7b is made of stainless steel wire mesh with a pore size of 0.074mm. The pore size is smaller than the diameter of ash and cement particles, which can effectively block ash and cement particles from passing through, while allowing water to pass through smoothly.
[0020] The first signal pipe 2, the second signal pipe 3, the overflow pipe 4, the exhaust pipe 5, and the filling pipe 6 are arranged sequentially in the horizontal direction, with a distance of at least 30cm between them to avoid being too concentrated and to reduce the impact force on the plate 1. In addition, the overflow pipe 4, the exhaust pipe 5, and the filling pipe 6 are all located close to the top edge of the plate 1. Specifically, the first signal pipe 2 is located 200mm from the top edge of the plate 1, and the second signal pipe 3 is located 500mm from the top edge of the plate 1. Specifically, the first signal pipe 2 is located above the second signal pipe 3. The second signal pipe 3 is used to control the first ash dropping height of the layering channel, and the first signal pipe 2 is used to control the second ash dropping height of the inlet channel.
[0021] The usage process of this utility model is as follows:
[0022] During the backfilling preparation work, the filter screen assembly 7 is first installed on the inner port of the reserved overflow pipe 4 and tied securely with the binding wire 8. When the backfill material enters the backfilling area, when the ash surface reaches the position of the overflow pipe 4, the water is smoothly discharged through the filter screen assembly 7 and flows into the mined-out access through the guide valve 6a. At this time, the ash and cement particles are blocked by the filter screen 7b and retained in the backfilling pipe 6. The water at the top of the backfill is effectively removed, while avoiding the loss of ash and cement particles, thus improving the quality of the backfill and the top connection rate.
