Description

Technical Field

[0001] This invention relates to the field of drainage equipment technology, and in particular to a low-vibration and low-noise drainage device. Background Technology

[0002] A goaf is a cavity or void left after coal or gangue has been extracted during coal mining operations. Due to its sunken shape and complex underground hydrological environment, a goaf is prone to water accumulation. To prevent excessive water accumulation and subsequent mine collapses, drainage pipes are needed to promptly drain the water. However, the water in a goaf often contains many impurities and a large amount of silt.

[0003] The existing patent (publication number: CN217977943U) drainage device uses a fixed filter plate, which is fixedly installed inside the drainage pipe and divides the drainage pipe into a first drainage channel and a second drainage channel. The position of the adjustable filter plate is adjustable inside the drainage pipe and is stacked with the fixed filter plate. Both the fixed filter plate and the adjustable filter plate are provided with filter mud holes that connect the first drainage channel and the second drainage channel.

[0004] The aforementioned patent uses filter plates and unblocking columns to perform preliminary filtration of sewage drawn into the drainage equipment and unblocks the filter holes. However, it cannot effectively treat the sludge that has settled on the inner wall of the pipe over a long period of time, which leads to an increasing accumulation of sludge in the pipe and affects the filtration efficiency of the filter plate for sewage.

[0005] Therefore, a low-vibration and low-noise drainage device is proposed. Summary of the Invention

[0010] Furthermore, the water suction pipe is connected to the piston sleeve, and the front end of the piston sleeve has an extension port.

[0011] Furthermore, the water suction pipe is equipped with a one-way input valve, and the transition port is equipped with a one-way output valve.

[0013] Furthermore, the transmission cleaning mechanism also includes two sets of connecting parts fixedly installed on the left side of the lower inner end face of the soundproof housing. A rotating shaft is rotatably connected between the two sets of connecting parts. Gear 1 is fixedly installed on the outer surface of the output shaft, and gear 2 is fixedly installed on the outer surface of the rotating shaft corresponding to gear 1. Gear 1 and gear 2 mesh with each other.

[0014] Furthermore, a gear three is fixedly installed on the front side of the outer surface of the rotating shaft corresponding to the filter housing. A gear ring is rotatably connected to the outer surface of the filter housing. The gear ring meshes with the gear three. A scraper is provided inside the filter housing. The scraper is arc-shaped and closely attached to the inner wall of the filter housing, and is located on the rear side of the filter plate. Multiple sets of scrapers are provided, and all of them are fixedly connected to the inner side of the gear ring.

[0015] Furthermore, the vibration cleaning mechanism includes a rotating shaft rotatably connected to the center of the front end face of the filter plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, by setting up a buffer component and a soundproof shell, can buffer and reduce the vibration of the entire equipment, thereby preventing the equipment from shaking and generating noise during operation. At the same time, it can also protect the equipment and prevent vibration from affecting the service life of the equipment. Secondly, the soundproof shell can prevent external dust and other adverse factors from corroding the equipment, and can also isolate the noise generated during the operation of the equipment, preventing the noise from being transmitted and affecting the operators.

[0019] 2. The present invention uses a drainage and filtration mechanism with the output shaft of a motor as the power source, so that the piston plate reciprocates inside the piston sleeve, and draws the external sewage into the piston sleeve for filtration through the suction pipe, and discharges it from the outlet, thus completing the sewage collection and preliminary filtration. No manual assistance is required, which saves labor.

[0020] 3. This invention utilizes a transmission cleaning mechanism, which operates simultaneously with the drainage filtration mechanism. This causes the scraper inside the filter housing to rotate with the toothed ring, thereby scraping away the sludge deposited inside the filter housing from its inner wall and dispersing it into the water. The sludge is then discharged with the water flow, preventing the presence of sludge from affecting wastewater filtration. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 7 The present invention provides a technical solution:

[0036] A low-vibration, low-noise drainage device includes a soundproof housing 1. A buffer assembly 2 is fixedly installed on the lower end face of the soundproof housing 1. A water suction pipe 3 is connected to the front side of the upper end face of the soundproof housing 1. One end of the water suction pipe 3 is connected to a spherical filter head 5. A water outlet 4 is opened at the front end of the soundproof housing 1. A motor 6 is fixedly installed on the right rear side of the lower end face inside the soundproof housing 1. An output shaft 7 is provided at the front end of the motor 6. A piston sleeve 8 is provided on the front side of the motor 6. The piston sleeve 8 is fixedly connected to the soundproof housing 1. A drainage filtration mechanism is provided inside the piston sleeve 8. A transmission cleaning mechanism is provided on the left side of the motor 6. The drainage filtration mechanism includes a piston plate 10 and a transmission column 9 provided inside the piston sleeve 8. The transmission column 9 is located on the rear side of the piston plate 10. The piston plate 10 is slidably connected inside the piston sleeve 8. The output shaft 7 extends into the piston sleeve 8 and is fixedly connected to the transmission column 9. The drainage filtration mechanism is driven by the output shaft 7 of the motor 6, thereby causing the piston plate 10 to move in a circular motion. The piston sleeve 8 reciprocates inside, and draws external sewage into the piston sleeve 8 for filtration through the suction pipe 3, and discharges it from the outlet 4, completing sewage collection and preliminary filtration without the need for manual assistance, thus saving labor. The buffer assembly 2 is provided in four sets, symmetrically arranged at the four corners of the soundproof shell 1, and consists of springs, buffer columns, buffer sleeves and stabilizing plates. The drainage filtration mechanism also includes a transmission groove 11 with an annular opening on the outer surface of the transmission column 9. A socket column 12 is slidably connected inside the transmission groove 11. A push rod 13 is fixedly installed at the upper end of the socket column 12. One end of the push rod 13 is fixedly connected to the piston plate 10. A sliding sleeve 14 is fixedly installed on the inner wall of the piston sleeve 8 corresponding to the push rod 13. The push rod 13 is slidably connected inside the sliding sleeve 14. The suction pipe 3 is connected to the piston sleeve 8. An overpass 15 is opened at the front end of the piston sleeve 8. A one-way input valve is provided inside the suction pipe 3, and a one-way output valve is provided inside the overpass 15.

[0037] By adopting the above technical solution, firstly, when it is necessary to drain the sewage in the mining goaf, one end of the suction pipe 3 carrying the spherical filter head 5 of this equipment is placed in the water. Then, the motor 6 is started, causing the output shaft 7 of the motor 6 to rotate. When the output shaft 7 of the motor 6 rotates, it will drive the transmission column 9 to rotate. The transmission groove 11 on the outer surface of the transmission column 9, which is annular, will cause the socket 12 inserted in the transmission groove 11 to move with the rotation of the transmission column 9, and transmit the displacement to the push rod 13, causing the push rod 13 to reciprocate inside the sliding sleeve 14. The piston plate 10, which is fixedly installed at the other end of the push rod 13, also reciprocates inside the piston sleeve 8. When the piston plate 10 moves to the rear end inside the piston sleeve 8, it will open the one-way input valve in the suction pipe 3, thereby drawing water from the outside through the spherical filter head 5. The piston sleeve 8 is plugged inside, while the spherical filter head 5 separates larger particles in the sewage. When the piston plate 10 moves forward inside the piston sleeve 8, it opens the one-way output valve in the transition port 15 and discharges the sewage inside the piston sleeve 8 into the filter housing 16. After entering the filter housing 16, the sewage is filtered by the filter plate 17 and discharged from the outlet 4, flowing into the external collection device, thus completing the drainage operation. Secondly, the buffer component 2 can buffer and dampen the overall equipment, thereby preventing shaking and noise during equipment operation. It can also protect the equipment and prevent vibration from affecting the service life of the equipment. Furthermore, the soundproof housing 1 can prevent external dust and other adverse factors from corroding the equipment and can also isolate the noise generated during equipment operation, preventing noise from being transmitted and affecting the operators.

[0038] like Figure 2 , Figure 3 , Figure 7As shown, the transmission cleaning mechanism includes a filter housing 16 fixedly installed at the front end of the piston sleeve 8. The filter housing 16 is interconnected with the piston sleeve 8 through an interface 15. A filter plate 17 is fixedly installed in the middle of the interior of the filter housing 16. The front end of the filter housing 16 is interconnected with the water outlet 4. The transmission cleaning mechanism also includes two sets of connecting parts 19 fixedly installed on the left side of the lower end face of the interior of the sound insulation housing 1. A rotating shaft 20 is rotatably connected between the two sets of connecting parts 19. A gear 18 is fixedly installed on the outer surface of the output shaft 7. The outer surface of the rotating shaft 20... Gear 21 is fixedly installed on the surface corresponding to gear 18. Gear 18 and gear 21 mesh with each other. Gear 32 is fixedly installed on the front side of the outer surface of the rotating shaft 20 corresponding to the filter housing 16. A toothed ring 23 is rotatably connected to the outer surface of the filter housing 16. The toothed ring 23 meshes with gear 32. A scraper 24 is provided inside the filter housing 16. The scraper 24 is arc-shaped and closely attached to the inner wall of the filter housing 16. It is located on the rear side of the filter plate 17. Multiple sets of scrapers 24 are provided, and all of them are fixedly connected to the inner side of the toothed ring 23.

[0039] By adopting the above technical solution, when the output shaft 7 rotates, it will drive the gear 18 to rotate. The gear 18 will mesh with the gear 21 on the rotating shaft 20, thereby causing the rotating shaft 20 to drive the gear 22 to rotate. The rotation of the gear 22 will drive the gear ring 23 to rotate, thereby causing the gear ring 23 to rotate and drive the scraper 24 to rotate. Since the scraper 24 is set close to the inner wall of the filter housing 16, it will scrape the sludge settled inside the filter housing 16 away from the inner wall of the filter housing 16 and scatter it in the water, which will be discharged with the water flow, thus avoiding the presence of sludge from affecting the filtration of sewage.

[0040] like Figure 8 , Figure 9 , Figure 10 As shown, the oscillating cleaning mechanism includes a rotating shaft rotatably connected to the center of the front end face of the filter plate. Multiple sets of transmission blades are fixedly installed on the outer surface of the rotating shaft. The multiple sets of transmission blades are arranged in a ring and dispersed. A rubber brush is fixedly installed at the rear end of the transmission blades corresponding to the filter plate. The oscillating cleaning mechanism also includes an elastic head set at the rear side of the filter plate. The rotating shaft passes through the filter plate and extends to the rear side to be fixedly connected to the elastic head. Multiple sets of oscillating columns are fixedly installed at the rear end face of the filter plate corresponding to the elastic head.

[0041] By adopting the above technical solution, when water flows through the filter plate 17 and then through the filter housing 16, it will wash the drive blades 26 set on the front side of the filter plate 17, thereby causing the rotating shaft 25 to carry the drive blades 26 to rotate. At the same time as the drive blades 26 rotate, the rubber brush 27 will also rotate synchronously and rotate closely against the front end face of the filter plate 17, thereby further cleaning the front end face of the filter plate 17 and preventing the pores of the filter plate 17 from becoming clogged. Secondly, when the rotating shaft 25 rotates, it will simultaneously carry the elastic head 28 set on the rear side of the filter plate 17 to rotate, causing the elastic head 28 to continuously collide with multiple sets of oscillating columns 29, thereby causing the oscillating columns 29 to oscillate and transmitting the vibration to the filter plate 17, further shaking and removing debris from the clogged pores. With the rubber brush 26 and scraper 24, the filter plate 17 can be thoroughly cleaned, thereby improving the practicality of the equipment.

[0042] Working Principle: First, when it is necessary to drain the sewage in the mining goaf, the suction pipe 3 of this equipment, carrying one end of the spherical filter head 5, is placed in the water. Then, the motor 6 is started, causing the output shaft 7 of the motor 6 to rotate. When the output shaft 7 of the motor 6 rotates, it will drive the transmission column 9 to rotate. The transmission groove 11 on the outer surface of the transmission column 9, which is annular, will cause the socket 12 inserted inside the transmission groove 11 to move with the rotation of the transmission column 9, and transmit the displacement to the push rod 13. This causes the push rod 13 to reciprocate inside the sliding sleeve 14. The piston plate 10, which is fixedly installed at the other end of the push rod 13, also reciprocates inside the piston sleeve 8. When the piston plate 10 is inside the piston sleeve 8... When the piston moves to the rear, it opens the one-way inlet valve in the suction pipe 3, allowing external water to be drawn into the piston sleeve 8 through the ball filter head 5. The ball filter head 5 separates larger particles in the wastewater. When the piston plate 10 moves to the front inside the piston sleeve 8, it opens the one-way outlet valve in the transition port 15, discharging the wastewater inside the piston sleeve 8 into the filter housing 16. After entering the filter housing 16, the wastewater is filtered by the filter plate 17 and discharged from the outlet 4, flowing into the external collection device, thus completing the drainage operation. Secondly, when the output shaft 7 rotates, it drives gear 18 to rotate. Gear 18 then meshes with gear 21 on the rotating shaft 20, further driving the flow of water. The rotating shaft 20 drives the gear 22 to rotate, which in turn drives the gear ring 23 to rotate. This, in turn, drives the scraper 24 to rotate. Since the scraper 24 is positioned close to the inner wall of the filter housing 16, it scrapes away the sludge deposited inside the filter housing 16, scattering it in the water and allowing it to flow out with the water flow. This prevents the sludge from affecting the wastewater filtration process. When the water flows through the filter plate 17 and then through the filter housing 16, it washes the drive blades 26 positioned in front of the filter plate 17. This causes the rotating shaft 25 to drive the drive blades 26 to rotate. Simultaneously, the drive blades 26 rotate, causing the rubber brush 27 to rotate in close contact with the filter. The front end of the filter plate 17 rotates to further clean it, preventing clogging of the pores. Simultaneously, the rotating shaft 25 rotates, carrying the elastic head 28 on the rear side of the filter plate 17. This causes the elastic head 28 to continuously collide with multiple sets of vibrating columns 29, causing them to vibrate and transmitting the vibrations to the filter plate 17. This further vibrates and removes debris from the clogged pores. Combined with the rubber brush 26 and scraper 24, the filter plate 17 is thoroughly cleaned, improving the equipment's practicality. The buffer assembly 2 provides overall shock absorption, preventing shaking and noise during operation.Simultaneously, it provides safety protection for the equipment, preventing vibration from affecting its lifespan. Secondly, the soundproof enclosure 1 prevents external dust and other adverse factors from corroding the equipment, and also isolates the noise generated during operation, preventing noise transmission and impacting operators.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
