Description

Technical Field

[0001] The present invention relates to the field of spontaneous combustion monitoring in the gob area of coal mines, and specifically to a fully automatic mine-used passive dust and water filtering magnetic trigger type water discharging device used in the mine-used laser multi-gas beam tube monitoring and warning system for spontaneous combustion in coal mines Background Art

[0002] At present, the monitoring and warning methods for spontaneous combustion in the gob area mainly adopt the beam tube monitoring and warning system. The traditional beam tube monitoring system samples underground gas through long-distance beam tubes to the ground gas chromatograph for analysis. The system has disadvantages such as poor real-time performance, it is difficult to ensure no leakage along the pipeline, large maintenance workload, and complex operation of the chromatograph equipment. To overcome the disadvantages of the traditional beam tube, the industry has developed an underground type laser multi-gas beam tube monitoring system in the past two years. Although some problems have been solved, the application effect is not ideal. The laser multi-gas analysis equipment has extremely high requirements for dust and water filtration. Especially in the complex coal mine environment, the gas extracted from the gob area is mixed with a large amount of water vapor and dust. The equipment often fails due to unreasonable air extraction treatment in the pipeline, resulting in system paralysis. The commonly used water discharging devices at present are as follows: One is manual water discharging, where a filter water bucket is placed at a designated place, and patrol personnel are regularly arranged to observe the water discharge, which has low efficiency and a large workload; the other is a mine-used intrinsically safe fully automatic water discharging device, whose working efficiency and reliability are greatly guaranteed, but it needs to consider wire-pulling power supply, which is relatively complex for construction, subsequent use and maintenance Summary of the Invention

[0003] Aiming at the above deficiencies of the prior art, the present invention provides a fully automatic mine-used passive dust and water filtering magnetic trigger type water discharging device that is more suitable for the monitoring requirements of spontaneous combustion in the gob area of coal mines. This device does not require power supply, has a small volume, is convenient to install, has high efficiency in treating water vapor, is beneficial to the stability of the underground gob area type laser multi-gas beam tube monitoring system, improves the operation life of the system underground, solves the problem that air extraction cannot be carried out due to water vapor condensation in long-distance gas path transmission, and ensures the authenticity of long-distance air extraction

[0004] To achieve the above technical objectives, the technical solution of the present invention is as follows

[0005] The fully automatic mine-used passive dust and water filtering magnetic trigger type water discharging device includes an air inlet system, an air outlet system, a drainage system and a main housing. The air inlet system includes an air inlet joint, an air inlet pipe and a pressure gauge. The air outlet system includes an air outlet joint, an air outlet pipe and a pressure gauge. The main housing is provided with an upper cover and a lower cover. The air inlet pipe and the air outlet pipe pass through the upper cover, and support feet are assembled at the lower part of the lower cover

[0006] The main housing is divided into upper and lower compartments by a partition plate. Among them, the upper compartment is a gas compartment, and the lower compartment is a water storage compartment. A multi-stage condensate and dust filtration device is arranged at intervals in the gas compartment. The intake pipe of the intake system is connected to the lower part of the gas compartment body, and the outlet pipe of the outlet system is connected to the upper part of the gas compartment body. After the mixed gas enters the lower part of the gas compartment from the intake pipe, it passes through the condensate and dust filtration device step by step upward for condensate and dust filtration, and then flows out from the outlet pipe at the upper part of the gas compartment.

[0007] A floating device is arranged in the water storage compartment. Magnetic substances are installed at the corresponding positions of the top of the floating device and the lower part of the partition plate. A drainage system is installed at the lower part of the water storage compartment. The drainage system can be activated when the floating device and the partition plate are magnetically attracted to each other for drainage.

[0008] For the fully automatic passive dust and water filtration magnetic trigger type water discharging device for mine use as described above, the partition plate includes a V-shaped structure, and a strong magnet and a water guiding hole are arranged at the bottom. The filtered water can flow from the water guiding hole to the water storage compartment.

[0009] Further, the floating device includes a float. A sealing platform is arranged at the top of the float. The number and position of the sealing platforms correspond to the number and position of the water guiding holes. When the float and the partition plate are magnetically attracted to each other, the sealing platform can contact and cooperate with the water guiding hole to isolate the water storage compartment from the gas compartment, forming two independent spaces.

[0010] For the fully automatic passive dust and water filtration magnetic trigger type water discharging device for mine use as described above, one or more V-shaped water filtration sheets are arranged in each stage of the condensate and dust filtration device. The bottom of the V-shaped water filtration sheet is open, so that the water filtered by the V-shaped water filtration sheet can flow down from the bottom of the V-shaped water filtration sheet.

[0011] Further, some or all of the V-shaped water filtration sheets include stainless steel powder metallurgy sheets and powder metallurgy sheet bottoms. The stainless steel powder metallurgy sheets are located on both sides of the powder metallurgy sheet bottom and extend outward. A number of stainless steel dust filtration nets are also distributed on the stainless steel powder metallurgy sheets. Preferably, the pores of the powder metallurgy sheets in the upper-stage condensate and dust filtration device are smaller than the pores of the powder metallurgy sheets in the lower-stage condensate and dust filtration device.

[0012] For the fully automatic passive dust and water filtration magnetic trigger type water discharging device for mine use as described above, the drainage system includes an intake pressure balance valve body, an intake pressure balance conduit, a water discharging valve body and a water discharging conduit. The intake pressure balance conduit and the water discharging conduit penetrate the floating device. The intake pressure balance valve body and the water discharging valve body are located at the lower part of the water storage compartment. One end of each of them close to the floating device is connected with a switch pull rod. The other end of the switch pull rod extends outside the intake pressure balance conduit or the water discharging conduit, and the end is respectively connected with an adjusting device.

[0013] Further, the adjusting device includes an adjusting cross beam and an adjusting nut. One end of the adjusting nut passes through the adjusting cross beam and maintains a certain distance from the upper plane of the floating device. By adjusting the distance between the adjusting nut and the upper plane of the floating device, the sensitivity of the float to rise and release water can be controlled.

[0014] For the fully automatic passive dust and water filtering magnetic trigger type water release device for mine use as described above, a liquid level gauge is further provided on the side of the water storage bin of the main housing for observing the water storage height in the water storage bin, which is convenient for maintenance.

[0015] A working method of using the fully automatic passive dust and water filtering magnetic trigger type water release device for mine use as described above includes the following steps:

[0016] Step 1: A large amount of water vapor is contained in the mixed gas extracted from the goaf. These gases enter the intake pipe of the device through the laid bundle pipe line. Through the intake pipe, water and gas are transported to the bottom of the gas bin. After the air flow impacts the isolation plate, the liquid water flows into the water storage bin through the water guiding holes. This is the first-stage treatment unit.

[0017] Step 2: For the mixed gas flowing into the gas bin through the intake pipe, in the lower-layer condensate filtering device, by using the principle of gas commutation and the inertia impact of water molecules on the V-shaped water filtering pieces, water, gas, and dust are filtered, and most of the dust particles and water vapor in the mixed gas are filtered. This is the second-stage treatment unit.

[0018] Step 3: After being treated by the second unit, the mixed gas enters the upper-layer condensate filtering device for further treatment of the fine particulate dust in the mixed gas. Finally, the treated gas flows out from the top outlet pipe and is transported back to the bundle pipe. This is the third-stage treatment unit. In addition, the water filtered out by the upper-layer condensate filtering device flows into the lower water storage bin through the powder metallurgy sheet bottom plate of the V-shaped water filtering pieces in the upper-layer condensate dust filtering device.

[0019] Step 4: During the process of filtering water and dust in the condensate filtering device, the intake pressure balance valve body and the water release valve body are in a normally closed state, so that the outside air cannot enter the device and the water in the housing cannot flow out.

[0020] Step 5: As the device continuously filters water and dust, the separated or filtered water continuously flows into the water storage bin through the water guiding holes on the isolation plate.

[0021] Step 6: As the liquid level in the water storage bin continues to rise, the float starts to rise under the influence of the buoyancy of the water. When it rises to a certain distance from the partition board, under the influence of the magnetic force of the magnet, the float will be instantaneously adsorbed onto the magnet on the partition board. At this time, the sealing platform on the float comes into contact and cooperation with the water guide hole on the partition board, isolating the water storage bin from the gas bin, forming two independent spaces. At the same time, the upward movement of the float drives the switch pull rod connected to the intake pressure balance valve body and the water discharge valve body upward, thereby opening the intake pressure balance valve body and the water discharge valve body. The outside air enters the top plate of the water storage bin from the intake pressure balance valve body, and the water in the water storage bin flows out through the water discharge valve body.

[0022] Step 7: As the liquid level in the water storage bin drops, the float is always adsorbed on the magnet. When the water in the water storage bin is completely drained, under the influence of its own weight, the float disengages from the magnet and drops to the bottom plate of the water storage bin. The intake pressure balance valve body and the water discharge valve body return to their initial states, completing an automatic water discharge process.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The mine-used passive dust and water filtration magnetic-triggered water discharge device of the present invention is very suitable for the needs of fire monitoring in coal mine gob areas, realizing a fully automatic dust and water filtration process without manual participation during the air extraction process. Moreover, this device is not simply an air extraction filtration device, but can not only achieve air extraction and filtration of the internal gas in the gob area, but also detect whether the air extraction state of the entire air extraction pipeline is normal, and has the function of diagnosing the pipeline along the line through a pressure gauge, solving the drawback that the traditional beam tube cannot be extracted due to the blockage of condensed water in the pipeline during long-distance air extraction, and can also achieve the function of filtering dust from the gas sample, with higher on-site practical value.

[0025] 2. The mine-used passive dust and water filtration magnetic-triggered water discharge device of the present invention has a simple structure and a small volume. Its construction and installation process can completely follow the installation method of ordinary coal mine equipment, and can be installed in a wall-mounted or standing manner without special technology.

[0026] 3. Compared with the traditional water filtration device, the mine-used passive dust and water filtration magnetic-triggered water discharge device of the present invention has improved water and dust filtration capabilities, and is equipped with an air extraction state display function. The filtering material is cheap and easy to use, and there is no need for manual participation in water discharge, ensuring the real-time and authenticity of air extraction, and more accurately transmitting the gas sample at the potential hazard point to the analysis device, which is of great significance for preventing fire disasters in the gob area and ensuring the safety of workers.

[0031] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0032] Embodiment 1

[0033] Refer to Figure 1 , Figure 1 This is a schematic structural diagram of the passive dust and water filtering magnetic trigger type water discharging device for mines in this embodiment, including an air inlet system, an air outlet system, a drainage system and a main housing 9. The air inlet system includes an inlet joint 1, an inlet pipe 7 and a pressure gauge 2. The air outlet system includes an outlet joint 3, an outlet pipe 8 and a pressure gauge 2. The inlet pipe 7 and the outlet pipe 8 are made of PVC pipes. The connecting parts of the components in the air inlet system and the air outlet system are all connected by a threaded connection with a sealing ring.

[0034] The main housing 9 adopts a rectangular structure, which is convenient for manufacturing. The main housing 9 is provided with an upper cover 4 and a lower cover 30. An air inlet pipe 7 and an air outlet pipe 8 penetrate through the upper cover 4. Supporting feet 32 are assembled at the lower part of the lower cover 30. Sealing rings 5 for the upper cover and sealing rings 29 for the lower cover are respectively provided at the contact parts between the upper cover 4 and the lower cover 30 and the housing, and upper and lower seals are achieved through connection by multiple groups of bolts.

[0035] The inside of the main housing 9 is divided into upper and lower compartments by a partition plate 14. Among them, the upper compartment is a gas compartment 6, and the lower compartment is a water storage compartment 25. Two-stage condensate and dust filtration devices are arranged in the gas compartment 6, namely a first-stage condensate and dust filtration device 12 and a second-stage condensate and dust filtration device 11. The first-stage condensate and dust filtration device 12 is located below the second-stage condensate and dust filtration device 11. The drainage system is connected to the lower part of the water storage compartment 25.

[0036] Furthermore, the air inlet pipe 7 of the air inlet system is connected to the lower compartment of the gas compartment 6, that is, the mixed gas in the air inlet pipe 7 first enters the lower layer of the first-stage condensate and dust filtration device 12. The air outlet pipe 8 of the air outlet system is connected to the upper compartment of the gas compartment 6, that is, after the mixed gas enters the lower part of the gas compartment 6 from the air inlet pipe 7, it sequentially passes through the condensate and dust filtration devices upward for condensate and dust filtration, and then flows out from the air outlet pipe 8 at the upper part of the gas compartment 6.

[0037] In this embodiment, the partition plate 14 is of a V-shaped structure, and a circular powerful magnet 15 for the partition plate and four convex water guide holes 16 are provided at the middle position of the bottom. The filtered water in the upper layer of the gas compartment 6 can flow into the lower water storage compartment 25 through the convex water guide holes 16. Preferably, the convex water guide holes 16 are of explosion-proof type.

[0038] In this embodiment, a plurality of V-shaped water filter sheets 10 are respectively arranged in the first-stage condensate and dust filtration device 12 and the second-stage condensate and dust filtration device 11. The V-shaped water filter sheets 10 are open at the bottom, and a number of stainless steel dust filter meshes are also distributed on the two side expansion plates. When the gas flows upward, it can only flow upward through the opening at the bottom of the V-shaped water filter sheet 10, and then when it diffuses around, it must pass through a number of stainless steel dust filter meshes. Through the design of this V-shaped water filter sheet 10 and the multi-stage condensate and dust filtration device, dust and water filtration of the mixed gas are achieved. The filtered water can flow down from the bottom of the V-shaped water filter sheet 10 and finally converge on the partition plate 14.

[0039] Furthermore, some or all of the V-shaped water filter sheets 10 adopt stainless steel powder metallurgy sheets 13 and powder metallurgy sheet bottom plates 38 to enhance the dust filtration effect of the V-shaped water filter sheets 10. The stainless steel powder metallurgy sheets 13 are located on both sides of the powder metallurgy sheet bottom plates 38 and extend outward. Preferably, the pores of the powder metallurgy sheets in the second-stage condensate and dust filtration device 11 are smaller than the pores of the powder metallurgy sheets in the first-stage condensate and dust filtration device 12, and powder metallurgy sheets with micron-sized pores can be used to achieve the best dust and water filtration effect.

[0040] In this embodiment, a floating device is provided in the water storage bin 25. The floating device includes a float 23. The float 23 keeps a certain distance from the isolation plate 14. When the water level in the water storage bin 25 rises, the float 23 can approach the isolation plate 14 under the buoyancy of water.

[0041] Further, at the middle position of the top of the float 23, a circular float strong magnet 24 and four float sealing bosses 22 are provided. The positions of the circular float strong magnet 24 and the four float sealing bosses 22 correspond to the positions of the circular isolation plate strong magnet 15 and the four convex water guiding holes 16 respectively. When the float 23 approaches the isolation plate 14 and the circular float strong magnet 24 magnetically attracts the circular isolation plate strong magnet 15, the four float sealing bosses 22 can contact and cooperate with the four convex water guiding holes 16 to isolate the water storage bin 25 from the gas bin 6, forming two independent spaces.

[0042] In this embodiment, a drainage system is installed at the lower part of the water storage bin 25. The drainage system can be started when the float 23 magnetically attracts the isolation plate 14 to drain water.

[0043] Further, the drainage system includes an intake pressure balance valve body 31, an intake pressure balance conduit 19, a water discharge valve body 34 and a water discharge conduit 21. The intake pressure balance conduit 19 and the water discharge conduit 21 are stainless steel pipes that vertically penetrate the float 23 upward. On both sides of the float 23, a hollow float guiding hole 26 is provided respectively. The size of the float guiding hole 26 matches the sizes of the intake pressure balance conduit 19 and the water discharge conduit 21. Under the limitation of the intake pressure balance conduit 19 and the water discharge conduit 21, the float 23 can only move in the vertical direction, thus ensuring that the circular float strong magnet 24 and the four float sealing bosses 22 can stably contact and cooperate with the circular isolation plate strong magnet 15 and the four convex water guiding holes 16.

[0044] In this embodiment, both the intake pressure balance valve body 31 and the water discharge valve body 34 are located below the lower cover 30 and are normally in a closed state. An intake pressure balance valve housing 36 is sleeved outside the intake pressure balance valve body 31. One end thereof close to the float 23 is connected with an intake pressure balance valve body pull rod 27. The intake pressure balance valve body pull rod 27 vertically extends upward outside the intake pressure balance conduit 19, and its end is respectively connected with an adjusting device. Similarly, a water discharge valve housing 35 is sleeved outside the water discharge valve body 34. One end thereof close to the float 23 is also connected with a corresponding switch pull rod. The other end of the switch pull rod extends outside the water discharge conduit 21, and its end is respectively connected with an adjusting device.

[0045] Further, a water discharge conduit water outlet hole 28 is provided at the contact position between the water discharge conduit 21 and the lower cover 30. It is opened when the switch pull rod of the water discharge valve body 34 is pulled upward, enabling the water in the water storage bin 25 to flow into the water discharge valve body 34 through the water discharge conduit water outlet hole 28. Preferably, a water discharge valve body sealing ring 33 is further provided at the lower part of the water discharge valve body 34.

[0046] Further, the adjusting device includes an adjusting cross beam 17 and adjusting nuts 18. The middle of the adjusting cross beam 17 is rotatably connected to the pull rod. One adjusting nut 18 is screwed at each end of the adjusting cross beam 17. One end of the adjusting nut 18 passes through the adjusting cross beam 17, and its bottom keeps a certain distance from the upper plane of the float 23. By adjusting the distance between the adjusting nut 18 and the upper plane of the float 23, the sensitivity of the float 23 rising to discharge water can be controlled. When the adjusting cross beam 17 and the adjusting nut 18 move downward, the distance between the adjusting nut 18 and the upper plane of the float 23 becomes smaller, the water discharge sensitivity increases, and the float 23 will quickly contact the adjusting nut 18 and push the pull rod upward, thereby starting the intake pressure balance valve body 31 and the water discharge valve body 34, and the water storage volume in the water storage bin 25 decreases; when adjusting in the reverse direction, the water discharge sensitivity decreases and the water storage volume increases.

[0047] Further, a powder metallurgy filter plug 37 is provided at the lower end of the intake pressure balance valve body 31 to filter the air entering the intake pressure balance conduit 19.

[0048] In this embodiment, a liquid level gauge 20 is further provided on the side of the water storage bin 25 of the main housing 9 for observing the water storage height in the water storage bin 25, which is convenient for maintenance.

[0049] The working method of this fully automatic passive dust and water filtration magnetic trigger type water discharge device for mine use includes the following steps:

[0050] Step 1: The mixed gas extracted from the goaf contains a large amount of water vapor. These gases enter the intake pipe 7 of the device through the laid bundle tube line. Through the intake pipe 7, water and gas are transmitted to the bottom of the gas bin 6. After the air flow impacts the isolation plate 14, the liquid water flows into the water storage bin 25 through the four convex water guiding holes 16. This is the first-stage treatment unit.

[0051] Step 2: The mixed gas flowing into the gas bin 6 through the intake pipe 7 is filtered for water, gas, and dust in the first-stage condensate filtration device 12 by using the principle of gas commutation and the inertial impact of water molecules on the V-shaped water filtration pieces 10, filtering most of the dust particles and water vapor in the mixed gas. This is the second-stage treatment unit.

[0052] Step 3: After being processed by the second unit, the mixed gas enters the second-stage condensate filtration device 11, where the dust of fine particles in the mixed gas is processed again. Finally, the processed gas flows out from the top outlet pipe 8 and is transported back to the beam tube pipeline. This is the third-stage processing unit. In addition, the water filtered out by the second-stage condensate filtration device 11 flows into the lower water storage bin 25 through the powder metallurgy sheet bottom plate 38 of the V-shaped water filter sheet 10 in the second-stage condensate dust filter device 11;

[0053] Step 4: During the water and dust filtration process of the condensate filtration device, the intake pressure balance valve body 31 and the drain valve body 34 are in a normally closed state. External air cannot enter the device, and the water inside the housing cannot flow out;

[0054] Step 5: As the device continuously filters water and dust, the separated or filtered water continuously flows into the water storage bin 25 through the four convex water guiding holes 16 on the partition plate 14;

[0055] Step 6: As the liquid level of the water storage bin 25 continues to rise, the float 23 begins to rise under the influence of the buoyancy of water. When it rises to a certain distance from the partition plate 14, under the influence of the magnetic force of the magnet, the circular strong magnet 24 on the float 23 of the float will be instantaneously adsorbed to the circular strong magnet 15 of the partition plate 14. At this time, the four float sealing bosses 22 on the float 23 are in contact and cooperation with the four convex water guiding holes 16 on the partition plate 14, separating the water storage bin 25 from the gas bin 6 to form two independent spaces. At the same time, the rise of the float 23 drives the switch pull rod connected to the intake pressure balance valve body 31 and the drain valve body 34 to move upward, thereby opening the intake pressure balance valve body 31 and the drain valve body 34. External air enters the top plate of the water storage bin 25 from the intake pressure balance valve body 31, and the water in the water storage bin 25 flows out through the drain valve body 34.

[0056] Step 7: As the liquid level of the water storage bin 25 drops, the float 23 is always adsorbed on the magnet. When the water in the water storage bin 25 is drained, under the influence of its own weight, the float 23 separates from the magnet, and the float 23 drops to the bottom plate of the water storage bin 25. The intake pressure balance valve body 31 and the drain valve body 34 return to their initial states, completing an automatic water drainage process.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.

A working method of the fully automatic passive dust and water filtering magnetic trigger type water discharging device for mine use according to claim 3, characterized in that, It includes the following steps: Step 1: A large amount of water vapor is contained in the mixed gas extracted from the goaf. These gases enter the intake pipe (7) of the device through the laid bundle pipe line. The water and gas are transmitted to the bottom of the gas storage bin (6) through the intake pipe (7). After the air flow impacts the isolation plate (14), the liquid water flows into the water storage bin (25) through the water guide holes. This is the first-stage treatment unit; Step 2: For the mixed gas flowing into the gas storage bin (6) through the intake pipe (7), in the lower-layer condensate water and dust filtration device, by using the principle of gas commutation and the inertia impact of water molecules on the V-shaped water filtration piece (10), the water, gas, and dust are filtered. Most of the dust particles and water vapor in the mixed gas are filtered. This is the second-stage treatment unit; Step 3: After being treated by the second unit, the mixed gas enters the upper-layer condensate water and dust filtration device for further treatment of the fine-particle dust in the mixed gas. Finally, the treated gas flows out from the top outlet pipe (8) and is transported back to the bundle pipe. This is the third-stage treatment unit. In addition, the water filtered out in the upper-layer condensate water and dust filtration device flows into the lower water storage bin (25) through the powder metallurgy sheet bottom plate (38) of the V-shaped water filtration piece (10) in the upper-layer condensate water and dust filtration device; Step 4: During the process of filtering water and dust in the condensate water and dust filtration device, the intake pressure balance valve body (31) and the water discharge valve body (34) are in a normally closed state. External air cannot enter the device, and the water in the shell cannot flow out; Step 5: As the device continuously filters water and dust, the separated or filtered water continuously flows into the water storage bin (25) through the water guide holes on the isolation plate (14); Step 6: As the liquid level of the water storage bin (25) continues to rise, the float (23) begins to rise under the influence of the buoyancy of water. When it rises to a certain distance from the isolation plate (14), under the influence of the magnetic force of the magnet, the float (23) will be instantaneously adsorbed to the magnet on the isolation plate (14). At this time, the sealing platform on the float (23) is in contact and cooperation with the water guide holes on the isolation plate (14), separating the water storage bin (25) from the gas storage bin (6) to form two independent spaces. At the same time, the rise of the float (23) drives the switch pull rod connected to the intake pressure balance valve body (31) and the water discharge valve body (34) to move upward, thereby opening the intake pressure balance valve body (31) and the water discharge valve body (34). External air enters the top plate of the water storage bin (25) from the intake pressure balance valve body (31), and the water in the water storage bin (25) flows out through the water discharge valve body (34); Step 7: As the liquid level of the water storage bin (25) drops, the float (23) is always adsorbed on the magnet. When the water in the water storage bin (25) is drained, under the influence of its own weight, the float (23) disengages from the magnet and drops to the bottom plate of the water storage bin (25). The intake pressure balance valve body (31) and the water discharge valve body (34) return to the initial state, completing an automatic water discharge process.
