Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bridge pile foundation construction technology, specifically a mud solidification treatment device in bridge pile foundation construction. Background Technology
[0002] Bridge pile foundation construction is a crucial part of bridge engineering, and its construction quality directly affects the stability and safety of the bridge. During the pile driving process, a large amount of mud is generated, which needs to be solidified to reduce environmental pollution and promote resource utilization.
[0003] Existing mud solidification methods can be divided into physical solidification and chemical solidification. Chemical solidification involves adding a solidifying agent to the mud, causing the solidifying agent to react chemically with the mud to form a solid state. However, long-term observation has revealed that after adding the solidifying agent to the mud, it is necessary to stir the mud to promote the mixing of the mud and the solidifying agent. However, existing stirring equipment is usually a unidirectional stirring method, which leads to uneven distribution of shear force and poor mixing effect between the mud and the solidifying agent.
[0004] Therefore, this utility model provides a mud solidification treatment device for bridge pile foundation construction. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a mud solidification treatment device for bridge pile foundation construction is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A mud solidification treatment device for bridge pile foundation construction, comprising a mixing tank, a cover plate fixedly connected to the top of the mixing tank, an inlet port in the middle of the cover plate, a filter assembly on the side wall of the mixing tank, a mixing shaft rotatably connected to the middle of the cover plate, a first motor fixedly connected to the top of the cover plate, a rotating shaft fixedly connected to the output end of the first motor, the mixing shaft and the rotating shaft being driven by a belt, a first gear rotatably connected to the middle of the mixing shaft, a second gear fixedly connected to the middle of the rotating shaft, the first gear and the second gear meshing with each other, a pair of fixed frames fixedly connected to the bottom of the first gear, multiple first mixing rods fixedly connected to the side wall of the fixed frames, multiple second mixing rods fixedly connected to the middle of the mixing shaft, and a feeding port on the cover plate. Through the above structure, by setting the mixing shaft, the first motor, and the rotating shaft, and cooperating with the first gear and the fixed frames, the first and second mixing rods can rotate in opposite directions relative to the mud, thereby improving the uniformity of the mixing of the mud and the solidifying agent and reducing the uneven mixing caused by the unidirectional mixing of existing mixing equipment.
[0007] Preferably, the filtration assembly includes a processing box fixed to the side wall of the mixing tank. A filter screen is rotatably connected inside the processing box. A discharge port is provided on the side wall of the processing box, and the filter screen is inclined towards the discharge port. A feed hopper is installed at the bottom of the processing box, and the feed hopper is inclined towards the inlet. A pair of support plates are fixed to the inner side wall of the processing box, and the support plates are in contact with the filter screen. With the above structure, the processing box, filter screen, and discharge port, together with the feed hopper, facilitate the filtration of the slurry added to the mixing tank, thereby reducing the entry of impurities such as stones in the slurry into the mixing tank, which could weaken the bonding force between the curing agent and the slurry and affect the curing of the slurry.
[0008] Preferably, a second motor is fixedly connected to the side wall of the processing box, and a cam is fixedly connected to the end of the second motor. The cam is located inside the processing box. With the above structure, the second motor and the cam can continuously lift the filter screen and make the filter screen collide with the support plate. The vibration generated by the collision can loosen some of the stones stuck on the filter screen and discharge them from the discharge port, which can reduce the situation where stones are stuck in the filter screen and cause filter screen blockage.
[0009] Preferably, a feeding tank is fixedly connected to the top of the cover plate. The feeding tank has a straight-through structure and a scale on its inner wall. A cylinder is fixedly connected to the top of the cover plate, and a baffle is fixedly connected to the end of the cylinder. With the above structure, the feeding tank, the scale, and the cylinder, along with the baffle, make it easy to measure the dosage of the curing agent by using the feeding tank and the scale when adding the curing agent, so as to achieve quantitative addition of the curing agent and improve the accuracy of the amount of curing agent additive.
[0010] Preferably, a scraper is fixed to the side wall of the fixing frame. The scraper is close to the top of the inner wall of the mixing tank and has an inclined structure. With the above structure, the scraper is connected to the fixing frame. By scraping the top of the inner wall of the mixing tank with the scraper, the slurry that exceeds the liquid surface during mixing can be reduced from adhering to the top of the inner wall of the mixing tank, thus preventing it from participating in the solidification process.
[0011] Preferably, a feeding hopper is fixedly connected to the top of the cover plate, and the feeding hopper is arranged correspondingly to the feeding port. The feeding hopper has a structure that is larger at the top and smaller at the bottom. Through the above structure, the feeding hopper is set to receive the scattered curing agent, so as to reduce the situation where the curing agent is scattered on the surface of the cover plate, which would lead to waste and affect the accuracy of the dosage.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The mud solidification treatment equipment for bridge pile foundation construction described in this utility model, by setting a stirring shaft, a first motor and a rotating shaft, and cooperating with a first gear and a fixed frame, can make the first stirring rod and the second stirring rod rotate in opposite directions with respect to the mud, so as to improve the uniformity of the mixing of mud and solidifying agent, and reduce the uneven mixing caused by the unidirectional stirring of existing stirring equipment.
[0014] 2. The mud solidification treatment equipment for bridge pile foundation construction described in this utility model, by setting up a treatment box, filter screen and discharge port, and cooperating with the feed hopper, can facilitate the filtration of mud added to the mixing tank, so as to reduce the entry of impurities such as stones in the mud into the mixing tank, which would weaken the bonding force between the solidifying agent and the mud and affect the solidification of the mud.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 2As shown in the embodiment of this utility model, a mud solidification treatment device for bridge pile foundation construction includes a mixing tank 1. A cover plate 11 is fixedly connected to the top of the mixing tank 1. An inlet 12 is opened in the middle of the cover plate 11. A filter assembly is provided on the side wall of the mixing tank 1. A mixing shaft 13 is rotatably connected to the middle of the cover plate 11. A first motor 14 is fixedly connected to the top of the cover plate 11. A rotating shaft 15 is fixedly connected to the output end of the first motor 14. The mixing shaft 13 and the rotating shaft 15 are driven by a belt. A first gear 16 is rotatably connected to the middle of the mixing shaft 13. A second gear 111 is fixedly connected to the middle of the rotating shaft 15. The first gear 16 and the second gear 111 mesh with each other. A pair of fixing frames 17 are fixedly connected to the bottom of the first gear 16. Multiple first mixing rods 18 are fixedly connected to the side wall of the fixing frames 17. Multiple second mixing rods 19 are fixedly connected to the middle of the mixing shaft 13. A feeding port 110 is opened on the cover plate 11. During operation... The slurry is added into the mixing tank 1 through the feed inlet 12. Then, the first motor 14 is started to drive the rotating shaft 15 and the stirring shaft 13 to rotate. At this time, the stirring shaft 13 will drive the second stirring rod 19 to rotate inside the mixing tank 1, while the rotating shaft 15 will drive the second gear 111 and the first gear 16 to rotate. This allows the fixed frame 17 to rotate in opposite directions with the first stirring rod 18 and the second stirring rod 19. At this time, the first stirring rod 18 and the second stirring rod 19 can stir the slurry from opposite directions inside the mixing tank 1. Then, the curing agent is added into the mixing tank 1 through the feed inlet 110, so that the curing agent is mixed with the slurry being stirred. Through the above structure, by setting the stirring shaft 13 with the first motor 14 and the rotating shaft 15, and cooperating with the first gear 16 and the fixed frame 17, the first stirring rod 18 and the second stirring rod 19 can rotate in opposite directions with the slurry, so as to improve the uniformity of the mixing of slurry and curing agent, and reduce the situation of uneven mixing caused by the unidirectional stirring of existing mixing equipment.
[0025] like Figure 1 and Figure 3As shown, the filtration assembly includes a processing tank 2, which is fixedly connected to the side wall of the mixing tank 1. A filter screen 21 is rotatably connected inside the processing tank 2. A discharge port 22 is provided on the side wall of the processing tank 2, and the filter screen 21 is inclined towards the discharge port 22. A feed hopper 23 is installed at the bottom of the processing tank 2, and the feed hopper 23 is inclined towards the inlet 12. A pair of support plates 24 are fixedly connected to the inner side wall of the processing tank 2, and the support plates 24 are in contact with the filter screen 21. During operation, when slurry is added to the mixing tank 1 from the inlet 12, the slurry flows out of the processing tank 2... The mud flows internally. When the mud passes through the filter screen 21, it will be filtered, thus removing stone impurities from the mud. At this time, the filter screen 21 is tilted towards the discharge port 22, causing some stones to be discharged from the discharge port 22. The filtered mud flows through the feed hopper 23 to the feed inlet 12 and then into the mixing tank 1. Through the above structure, the processing box 2, the filter screen 21, and the discharge port 22 are set up, and the feed hopper 23 is used to facilitate the filtration of the mud added to the mixing tank 1, so as to reduce the entry of stone and other impurities in the mud into the mixing tank 1, which would weaken the bonding force between the curing agent and the mud and affect the curing of the mud.
[0026] like Figure 1 and Figure 3 As shown, a second motor 3 is fixedly connected to the side wall of the processing tank 2, and a cam 31 is fixedly connected to the end of the second motor 3. The cam 31 is located inside the processing tank 2. During operation, when no more mud is injected, the second motor 3 is started to drive the cam 31 to rotate. At this time, when the protruding position of the cam 31 contacts the bottom of the filter screen 21, it can lift the filter screen 21. After the protruding part of the cam 31 passes the filter screen 21, the filter screen 21 will descend and collide with the support plate 24. At this time, the filter screen 21 can vibrate, thereby loosening some of the stones stuck in the filter screen 21 and rolling them out of the filter screen 21 to the discharge port 22. Through the above structure, the second motor 3 and the cam 31 are set so that the cam 31 can continuously lift the filter screen 21 and make the filter screen 21 collide with the support plate 24. The vibration generated by the impact can loosen some of the stones stuck on the filter screen 21 and discharge them from the discharge port 22, which can reduce the situation where stones are stuck in the filter screen 21 and cause blockage of the filter screen 21.
[0027] like Figure 1 and Figure 4As shown, a feeding tank 4 is fixedly connected to the top of the cover plate 11. The feeding tank 4 has a straight-through structure and a scale 41 is provided on the inner wall of the feeding tank 4. A cylinder 42 is fixedly connected to the top of the cover plate 11, and a baffle 43 is fixedly connected to the end of the cylinder 42. During operation, when adding curing agent to the mixing tank 1, the curing agent can be added to the feeding tank 4, and then the dosage of the curing agent can be observed through the scale 41. When the dosage is in a suitable ratio with the amount of mud in the mixing tank 1, the cylinder 42 is then activated to contract and the baffle 43 is closed. Plate 43 is removed from the bottom of the feeding tank 4. At this time, the curing agent in the feeding tank 4 will fall into the mixing tank 1 through the feeding port 110. Then, the cylinder 42 is activated to stretch and the baffle 43 closes the bottom of the feeding tank 4. With the above structure, the feeding tank 4, the scale 41 and the cylinder 42 are set up. With the baffle 43, it is convenient to make the dosage ratio through the feeding tank 4 and the scale 41 when adding the curing agent, so as to realize the quantitative addition of the curing agent and improve the accuracy of the amount of curing agent additive.
[0028] like Figure 2 As shown, a scraper 5 is fixedly connected to the side wall of the fixing frame 17. The scraper 5 is close to the top of the inner wall of the mixing tank 1. The scraper 5 has an inclined structure. When the fixing frame 17 rotates during operation, it will drive the scraper 5 to rotate. At this time, the scraper 5 contacts the inner wall near the top of the mixing tank 1 and can scrape off the mud that is adhering to the top of the inner wall of the mixing tank 1 and exceeds the liquid surface. The scraper 5 is inclined to the mud side, which can generate a downward thrust when scraping off the mud adhering to the inner wall of the mixing tank 1, so that it returns to the inside of the mixing tank 1. Through the above structure, the scraper 5 is connected to the fixing frame 17. By scraping the top of the inner wall of the mixing tank 1 with the scraper 5, the situation where the mud that exceeds the liquid surface during the mixing of mud adheres to the top of the inner wall of the mixing tank 1 and cannot participate in the solidification can be reduced.
[0029] like Figure 4 As shown, a feeding hopper 6 is fixedly connected to the top of the cover plate 11. The feeding hopper 6 is correspondingly arranged with the feeding port 110. The feeding hopper 6 has a structure that is larger at the top and smaller at the bottom. During operation, when the curing agent falls from the bottom of the feeding tank 4 to the feeding port 110, it will pass through the gap between the feeding hoppers 6 and then enter the mixing tank 1 through the feeding port 110. When the curing agent is scattered around, it will be caught by the feeding hoppers 6 and then guided into the mixing tank 1. Through the above structure, the feeding hopper 6 is set to catch the scattered curing agent, so as to reduce the situation where the curing agent is scattered on the surface of the cover plate 11, which would lead to waste and affect the accuracy of the dosage.
[0030] like Figure 2As shown, an extension plate 7 is fixedly connected to the middle of the second stirring rod 19. The extension plate 7 has an inclined structure. When the second stirring rod 19 rotates during operation, it will drive the extension plate 7 to rotate. At this time, the extension plate 7 and the second stirring rod 19 are inclined, which can generate a certain shear force when the extension plate 7 rotates in the mud. Through the above structure, the extension plate 7 is set to connect the second stirring rod 19, which can increase the contact surface between the second stirring rod 19 and the mud, and generate a certain shear force in the mud through the extension plate 7 to improve the stirring effect of the mud.
[0031] Working principle: The slurry is added to the mixing tank 1 through the inlet 12. Then, the first motor 14 is started, driving the rotating shaft 15 and the stirring shaft 13 to rotate. At this time, the stirring shaft 13 drives the second stirring rod 19 to rotate inside the mixing tank 1, while the rotating shaft 15 drives the second gear 111 and the first gear 16 to rotate. This allows the fixed frame 17 to rotate in opposite directions with the first stirring rod 18 and the second stirring rod 19. The first stirring rod 18 and the second stirring rod 19 can then stir the slurry from opposite directions inside the mixing tank 1. Then, the curing agent is added to the mixing tank 1 through the feed inlet 110, mixing the curing agent with the stirring slurry. Finally, the slurry is added to the mixing tank 1 through the feed inlet 12. During the process, the slurry flows from the treatment tank 2. When the slurry passes through the filter screen 21, it is filtered, removing stone impurities. At this time, the filter screen 21 tilts towards the discharge port 22, causing some stones to be discharged from the discharge port 22. The filtered slurry flows through the feed hopper 23 to the feed inlet 12 and then into the mixing tank 1. When no more slurry is injected, the second motor 3 is started to drive the cam 31 to rotate. At this time, when the protruding part of the cam 31 contacts the bottom of the filter screen 21, it can lift the filter screen 21. After the protruding part of the cam 31 passes the filter screen 21, the filter screen 21 will descend and collide with the support plate 24. This can cause the filter screen 21 to vibrate, thereby causing some stones to get stuck in the filter screen 21. The stones in tank 1 loosen and roll out from filter screen 21 to discharge port 22. When adding curing agent to mixing tank 1, the curing agent can be added to feeding tank 4, and the dosage of curing agent can be observed through scale 41. When the dosage is in proportion to the amount of mud in mixing tank 1, cylinder 42 is activated to retract, causing baffle 43 to move away from the bottom of feeding tank 4. At this time, the curing agent in feeding tank 4 will fall into mixing tank 1 through feeding port 110. Then, cylinder 42 is activated to extend, causing baffle 43 to close the bottom of feeding tank 4. When the fixing frame 17 rotates, it will drive scraper 5 to rotate. At this time, scraper 5 contacts the inner wall near the top of mixing tank 1 and can scrape during rotation. The slurry adhering to the top of the inner wall of the mixing tank 1 and exceeding the liquid surface is scraped off. The scraper 5 is inclined towards the slurry side, which can generate a downward thrust when scraping the slurry adhering to the inner wall of the mixing tank 1, so that it returns to the inside of the mixing tank 1. When the curing agent falls from the bottom of the feeding tank 4 to the feeding port 110, it will pass through the feeding hopper 6 and enter the mixing tank 1 through the feeding port 110. When the curing agent is scattered around, it will be caught by the feeding hopper 6 and then guided into the mixing tank 1. When the second stirring rod 19 rotates, it will drive the extension plate 7 to rotate. At this time, the extension plate 7 and the second stirring rod 19 are inclined, which can give the extension plate 7 a certain shear force when rotating in the slurry.
