Description

Technical Field

[0001] The present invention relates to the technical field of mine mining, in particular to a water collecting and discharging device for a negative pressure pipe of an air shaft. Background Art

[0002] Mine negative pressure is an important data reflecting the ventilation resistance of a mine. A sudden increase or decrease in negative pressure indicates that the roof of the mine's total return airway may have collapsed, the total return airway is blocked, or the main supply and main return ventilation facilities are short-circuited or damaged. The mine negative pressure is reflected by a U-shaped differential pressure gauge at the ground wind shaft or a negative pressure sensor is connected to the connecting pipe to display the data. Since coal dust and dust are generated during the mining process, in order to reduce or eliminate coal dust and dust, spray dust reduction measures are implemented in the mining area at the mining working face and return airway according to regulations. This results in relatively humid air in the mine's total return airway. The mine air volume is checked on the ground through the wind shaft. Affected by changes in air temperature, it is easy to cause the connected U-shaped differential pressure gauge or negative pressure sensor to display data. The air in the bundle pipe condenses into water droplets, which can easily clog the hose, thereby affecting the mine negative pressure data. Summary of the Invention

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-Figure 3 As shown, a water collecting and discharging device for a negative pressure pipe of an air shaft includes a water storage barrel 1, an air inlet pipe 2, an air outlet pipe 3, a drain pipe 4, a filter material, an electric valve No. 1 6, a manual valve 7, and a controller. The upper left portion of the water storage barrel 1 is fixedly connected to the air inlet pipe 2, and the lower right portion is fixedly connected to the air outlet pipe 3. The bottom of the water storage barrel 1 is fixedly connected to the drain pipe 4. A water-permeable filter material is installed in the middle of the water storage barrel 1. The middle of the air inlet pipe 2 and the air outlet pipe 3 are respectively installed with an electric valve No. 1 6 for controlling the on-off of gas. The middle of the drain pipe 4 is installed with a manual valve 7 for controlling the on-off of liquid. The two No. 1 electric valves 6 are respectively electrically connected to the controller. The controller is externally powered. The controller is a known prior art, such as a single-chip microcomputer and a PLC.

[0017] When in use, the air inlet pipe 2 and the air outlet pipe 3 are respectively connected to the negative pressure pipe, and then the two No. 1 electric valves 6 are controlled to open by the controller, and the manual valve 7 is manually operated to open and close at a fixed time. As the air passes into the water storage barrel 1 through the air inlet pipe 2, the condensed water contained in the air gathers at the bottom of the water storage barrel 1 until the manual valve 7 is opened and discharged from the drain pipe 4, while other debris can be intercepted and filtered by the filter material, reducing the blockage of the negative pressure pipe in the subsequent process, and then the air is discharged through the air outlet pipe 3.

[0018] The manual valve 7 includes a valve body 9, a valve cavity 10, a valve core 11, a through hole 12, a valve stem 13, and a regular hexagonal column 14. The valve body 9 is provided with a valve cavity 10, the valve body 9 is fixed to the drain pipe 4, the valve cavity 10 is connected to the inner cavity of the drain pipe 4, the valve core 11 is spherical, and a valve stem 13 is fixed to the right end of the valve core 11. The valve stem 13 is coaxial with the virtual spherical center of the valve core 11, the valve core 11 is sealed and rotatably connected in the valve core 11, and a through hole 12 is passed through the upper and lower parts. The valve stem 13 is rotatably connected to the valve body 9, and a regular hexagonal column 14 is coaxially fixed to the right end. When the valve core 11 is rotated to a certain position, the through hole 12 can be connected to the drain pipe 4. When the valve core 11 is rotated to a certain position, the through hole 12 can be sealed and closed by the inner wall of the valve body 9.

[0019] Furthermore, by clamping the regular hexagonal column 14 with a tool such as a wrench, the valve stem 13 can be manually rotated forward and backward, thereby adjusting the angular position of the valve core 11 and the through hole 12 relative to the valve body 9, and then making the through hole 12 unobstructed or blocked, thereby controlling the opening or closing of the manual valve 7.

[0020] The inner wall of the water storage barrel 1 is smooth, and the bottom inner wall is connected to a float 15 for sliding up and down. A support ring 16 is fixed to the inner wall of the water storage barrel 1. A compression spring 17 is fixed to the bottom end of the support ring 16 and the top of the float 15, and a vertical light rod 18 is fixed to the bottom end. The light rod 18 is sealed and slidably connected to the water storage barrel 1 up and down. A vertical rack 19 is fixed to the bottom end of the light rod 18. A gear 20 is coaxially fixed to the right part of the valve stem 13, and the rack 19 is engaged with the gear 20. The float 15 can float in the water. When the float 15 moves up and down, the gear 20 can be rotated forward and backward through the light rod 18 and the rack 19, thereby changing the angle of the valve core 11 relative to the valve body 9 to achieve the sealing and unobstructed through-hole 12.

[0021] Furthermore, when more and more condensed water accumulates at the bottom of the water storage barrel 1, the float 15 gradually moves upward under the action of buoyancy. At this time, the light rod 18 and the rack 19 that follow the float 15 upward use the cooperation of the rack 19 and the gear 20 to make the valve stem 13 and the valve core 11 rotate forward, so that the through hole 12 can gradually be connected with the drain pipe 4, and the condensed water can be released. As the volume of the condensed water gradually decreases, the float 15 gradually drops, and the light rod 18, the rack 19 and the gear 20 make the valve stem 13 and the valve core 11 reverse, thereby restoring the through hole 12 to be blocked by the valve body 9, that is, stopping drainage, thereby realizing automatic water discharge and water collection, which is simpler and more efficient than manual operation.

[0022] A contact ring 21 is fixed to the middle of the inner wall of the water storage barrel 1, and the upper and lower parts of the contact ring 21 are conical. The filter material includes a filter plate 22 and a support shaft 23. The middle part of the filter plate 22 is fixed with a support shaft 23 along the front and rear directions. The support shaft 23 penetrates the water storage barrel 1 and the contact ring 21 and is sealed and rotatably connected. The filter plate 22 is sealed and rotatably connected to the contact ring 21. The front part of the support shaft 23 is connected to the transmission shaft 24 in an axially sliding manner. The front part of the transmission shaft 24 is fixed with a handle 25 in the radial direction of the left and right, and a tension spring 26 is fixed to the rear end and the support shaft 23. The outer wall of the water storage barrel 1 is fixed with a cross-row. The handle 25 can be plugged into the left and right parts of the slot 27, and can be plugged into the upper and lower parts of the slot 27. The transmission shaft 24 has a tendency to move backward under the elastic tension of the tension spring 26 and can be plugged into the slot 27. The handle 25 can be released from the slot 27 when it is pulled forward to a certain position by an external force. When the handle 25 is plugged into the left and right parts of the slot 27, the filter plate 22 is in a horizontal state and is just closed with the middle part of the contact ring 21. When the handle 25 is plugged into the upper and lower parts of the slot 27, the filter plate 22 is in a vertical state and the middle part of the contact ring 21 is connected from top to bottom.

[0023] Furthermore, by manually pulling the handle 25 to disengage it from the slot 27, then rotating the handle 25, and then releasing the handle 25 to restore it to the socket 27, the posture of the handle 25 can be changed, and then the posture of the filter plate 22 relative to the contact ring 21 can be changed, that is, closed, conductive, or flipped. When the filter plate 22 is flipped, the air entering from the air inlet pipe 2 can be used to flush the filter plate 22. At this time, the No. 1 electric valve 6 where the air outlet pipe 3 is located is closed, and the manual valve 7 is opened, so that the debris filtered by or attached to the filter plate 22 can be discharged through the drain pipe 4, thereby cleaning the filter plate 22, ensuring the filtering effect of the filter plate 22 after long-term use, and reducing blockage.

[0024] The top of the water storage barrel 1 is fixedly connected with a water inlet pipe 28, and a No. 2 electric valve 29 is installed in the middle of the water inlet pipe 28. The No. 2 electric valve 29 is electrically connected to the controller.

[0025] Furthermore, when flushing and cleaning the filter plate 22, close the two No. 1 electric valves 6, open the manual valve 7 and the No. 2 electric valve 29, and then connect the water inlet pipe 28 to the external pressurized water source. Then, the water flow can be used to flush the filter plate 22, further improving the cleaning effect of the filter plate 22.

[0026] The top of the water storage barrel 1 is fixedly connected to a cleaning pipe 30 , and the end of the cleaning pipe 30 is sealed and threadedly connected to an end cap 31 .

[0027] Furthermore, close the No. 1 electric valve 6 and the No. 2 electric valve 29, open the manual valve 7, remove the end cover 31, and then extend the external air gun into the water storage barrel 1 through the cleaning pipe 30, and use compressed air to flush the upper inner wall of the water storage barrel 1, and even flush the bottom inner wall of the water storage barrel 1 through the penetration in the middle of the contact ring 21, so as to improve the cleaning effect of the inner wall of the water storage barrel 1 and the inner walls around the air inlet pipe 2 and the air outlet pipe 3, and further reduce the blockage of the negative pressure pipe.

[0028] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
