Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a wind and water linkage cleaning device. Background Technology
[0002] As the country places increasing emphasis on environmental protection, the production requirements for existing coal mines and non-metallic mineral enterprises are becoming more stringent. In order to avoid excessive environmental pollution in mining areas and the risk of collapse in goaf areas, most enterprises now use solid waste such as tailings, crushed stone, fly ash, and industrial slag from mines to make paste-like slurry that does not require dehydration. This slurry is then continuously pumped into underground goaf areas for filling using industrial pumps. This not only improves the resource extraction rate but also reduces land occupation and environmental pollution.
[0003] However, with the widespread use of filling technology, after filling is completed, a large amount of clean water is generally used to clean the pipeline manually by hand. The water volume is generally 1.5 to 2 times the pipeline volume. According to the actual situation on site, the effect of cleaning the pipeline by this method is not ideal. There are still cases where the pipeline is not cleaned properly. This will cause the residual slurry on the inner wall of the pipeline to clump together if it is not cleaned for a long time. Long-term accumulation will inevitably lead to pipe blockage, pipe bursting and other situations. In addition, a large amount of cleaning water flows into the filling working face and the underground water tank, affecting the concentration of the slurry and bringing a certain amount of labor intensity to the underground drainage.

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0019] It should be understood that the described embodiments are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0020] This utility model provides a wind and water linkage cleaning device, which facilitates the cleaning of residues inside filling pipes after use.
[0021] The present invention will be further described in detail below with reference to the accompanying drawings.
[0022] See Figure 1 , Figure 2 This utility model provides a wind and water linkage cleaning device, including: an air inlet pipe 10, the input end of which is connected to a gas generator 11, and the output end of which is connected to a first air inlet 122 of a pressure tank 12 for filling the pressure tank 12 with air; an air outlet pipe 13, the input end of which is connected to the air outlet of the pressure tank 12, and a first switch control valve 14 is provided on the air outlet pipe 13; and a water-air mixing tank 15, which is provided with a second air inlet 151, the second air inlet being connected to the air outlet pipe 13. The output end is connected for filling the water-air mixing tank 15 with air; the water-air mixing tank 15 is also provided with a water inlet 152, and a water inlet pipe 16 is connected to the water inlet for filling the water-air mixing tank 15 with water; the cleaning pipe 17 is connected to the outlet of the water-air mixing tank 15 at its input end, and is provided with a second switch control valve 18 and an electric three-way valve 19 on the cleaning pipe 17. The electric three-way valve 19 is located further away from the outlet of the water-air mixing tank 15 than the second switch control valve 18. The output end of the cleaning pipe 17 is connected to the filling pipe (not shown in the figure).
[0023] This utility model provides a wind and water linkage cleaning device. Through improvements in structure and composition, when cleaning of the filling pipe is required, the first switch control valve and the second switch control valve are opened. Compressed gas is generated from the gas generator and enters the water-gas mixing tank through the air inlet pipe, the air pressure tank, and the air outlet pipe. At the same time or sequentially, water enters the water-gas mixing tank through the water inlet pipe. In the water-gas mixing tank, liquid water and gas combine to form a pressurized gas-water mixed jet that flows into the cleaning pipe and enters the filling pipe from the outlet of the cleaning pipe for flushing, which facilitates the cleaning of residues inside the filling pipe after use.
[0024] Furthermore, compared to manually cleaning pipes with a handheld water hose, this method improves cleaning efficiency and reduces the amount of water required for cleaning pipes.
[0025] See Figure 2 In some embodiments, the electric three-way valve 19 includes a main pipeline and a branch pipeline. The main pipeline includes a first port 191 and a second port 192. One end of the branch pipeline is connected to the main pipeline, and the other end of the branch pipeline is connected to the pipeline between the electric three-way valve and the second switch control valve. One end of the main pipeline is connected to the cleaning pipeline, and the other end is connected to the feed inlet. When external materials are discharged, they enter the electric three-way valve through the feed inlet and mix with the air and water brought by the air and water outlet to form a slurry for filling.
[0026] See Figure 2 In some embodiments, the device further includes: an electrical control device 20; the electric three-way valve 19 includes: a valve body 193, the valve body including: a first inlet 194, a second inlet 195 and an outlet 196, the first inlet 194 is used to connect to the cleaning pipeline 17, the second inlet 195 is used to connect to the feed pipe, and the outlet 196 is connected to the filling pipeline. The valve body 193 has a movable valve core (not shown in the figure) inside, the valve core is connected to a drive motor (not shown in the figure), the drive motor is located on the side of the valve body and electrically connected to the electrical control device 20, for driving the valve core to move and switch between the first inlet 194 and the second inlet 195 within the valve body; thus, the valve core can be adjusted as needed under different conditions of gas pressurization and pipeline flushing.
[0027] See Figure 1 , Figure 2In some embodiments, four pressure tanks 12 are provided, arranged side by side. At least one pressure tank is provided with a first air inlet 122, and the air outlet of each pressure tank is connected to an air outlet pipeline. A third switch control valve 121 is provided between the air outlet of each pressure tank and the air outlet pipeline. The number of pressure tanks used can be selected according to the on-site usage environment. The side-by-side arrangement of the pressure tanks can increase the total storage capacity of compressed gas. The purpose of providing a third switch control valve between the air outlet of each pressure tank and the air outlet pipeline is to ensure the stability of the gas delivered to the water-gas mixing tank. The gas delivery can be carried out by opening all the third switch valves at the same time or by opening the third switch valves sequentially.
[0028] See Figure 1 In some embodiments, the volume of both the pressure tank 12 and the water-gas mixing tank 15 is 10m³. The volume of both the pressure tank and the water-gas mixing tank can be selected according to the amount of gas required on site. Moreover, the water-gas mixing tank is pre-stored with a portion of water, which can be more fully combined with the high-pressure gas to form a gas-water mixed jet when discharged, thereby enhancing the cleaning effect.
[0029] See Figure 1 , Figure 2 In some embodiments, the water-air mixing tank 15 is equipped with a liquid level monitoring sensor (not shown in the figure) and a pressure monitoring sensor (not shown in the figure); the liquid level monitoring sensor and the pressure monitoring sensor are electrically connected to the electrical control device 20; wherein, when the pressure sensor inside the water-air mixing tank detects that the pressure has decreased to a minimum preset value, the cleaning pipeline is closed, the first switch control valve is opened, and the gas generator charges the pressure tank to store energy; when the pressure sensor detects that the pressure has reached the working preset value, the first switch control valve is closed, and the cleaning pipeline continues to be opened to clean the pipeline; at the same time, the liquid level monitoring sensor is installed on the inner wall of the water-air mixing tank. When liquid is injected into the water-air mixing tank from the outside, the liquid level monitoring sensor starts monitoring. When the liquid level inside the water-air mixing tank reaches the liquid level monitored by the liquid level monitoring sensor, the liquid level monitoring sensor issues a prompt and stops injecting liquid into the water-air mixing tank.
[0030] See Figure 1 In some embodiments, the gas generator 11 is an air compressor; thus, different specifications of air compressors can be selected according to the actual working environment on site. In this embodiment, the standard of the selected air compressor is a pressure of 0.8 MPa and an air volume of 30 m³ / min. The air compressor can quickly provide the required pressurized gas, thereby improving the overall working efficiency of the cleaning device.
[0031] The air compressor is equipped with a dryer, a precision filter, and pneumatic valves. The pneumatic valves control the gas entering and exiting the compressor. The dryer removes moisture from the gas entering the compressor to prevent excessive moisture from damaging the equipment. The precision filter effectively intercepts fine particles, oil mist, and residual moisture to prevent them from entering the production process and affecting gas quality.
[0032] The implementation method of this utility model:
[0033] 1. After the filling work is completed, pump water to flush the filling pipeline. First, use water to flush and dilute the concentration of the slurry in the entire filling pipeline. When the concentration at the outlet of the filling pipeline is significantly lower, notify the operator to stop flushing.
[0034] Before cleaning the pipeline, it is necessary to store 5-8 cubic meters of water in the water-air mixing tank and pressurize it to 0.7 MPa-0.8 MPa. At the same time, the electric three-way valve should be switched to the cleaning pipeline.
[0035] 2. As the reversal is completed, high-pressure gas enters the water-gas mixing tank and the second switch control valve is opened. The high-pressure gas that has entered beforehand pushes the water in the water-gas mixing tank to form a gas-water mixed jet, which enters the filling pipeline through the cleaning pipeline for pipe cleaning operation.
[0036] When the pressure sensor on the pressure tank detects a pressure of 0.1 MPa, the second switch control valve closes and the first switch control valve opens, allowing the gas generator to store energy in the pressure tank and the water-gas mixing tank. When the pressure sensor detects a pressure of 0.7 MPa, the first switch control valve closes and the second switch control valve continues to open to clean the pipeline. The cycle of this process can be set via the display screen.
[0037] 3. When the gas at the end of the pipeline is ejected at high speed, it proves that the entire pipeline has been cleaned and dried. At this time, open all the control valves and use compressed gas to continuously blow into the pipeline for 10 minutes. The specific time can be set according to the site conditions. After all the slurry and water in the pipeline are removed, the system stops working and the cleaning operation ends.
