Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, and particularly to a mobile mixing device for on-site sea mud soil formation. Background Art

[0002] In recent years, with the development of China's economic construction, in coastal marine engineering construction, a large amount of sea mud is generated every year. Occupying land with sea mud can lead to the diffusion of pollutants and the destruction of the water environment. However, a large amount of earthwork is also required for economic construction, which will cause irreparable damage to the ecological environment. Therefore, the contradiction between such demands and environmental pollution and damage has become increasingly prominent. It is necessary to treat sea mud, crush the sea mud to the required diameter of sea mud particles, that is, the required fineness of sea mud particles, so as to realize the resource utilization of sea mud.

[0003] Sea mud is deposited in a static or slow-flowing water environment and is formed into unagglomerated soft fine particles or extremely fine particles through physical, chemical, and biochemical actions. It belongs to modern recent sediments. Sea mud generally has a high water content, a high clay content, poor drainage, extremely low strength, and some sea mud also has a relatively high organic matter content. It is a special soil that is difficult to directly utilize in engineering and generally needs to be mixed and solidified before it can be resourcefully treated. In the patent application with the patent number CN113547634A, an engineering material low-dust mixing device is disclosed. The mixing device in this application can only mix engineering materials such as sand, gravel, and cement, which are non-viscous materials, and is not suitable for mixing sea mud with high viscosity and difficult to stir and separate. Under construction conditions, the transmission shaft, as a weak link in the mechanical transmission structure, faces huge challenges. When the resistance required for the drum to stir sea mud increases, the transmission shaft needs to transmit a greater force. Exceeding its load-bearing range will cause it to break, affecting the service life of the transmission shaft. Moreover, once the transmission shaft breaks, the broken transmission shaft will swing back and forth when the equipment continues to operate. This will not only damage the surrounding equipment but also pose a safety hazard to the staff.

[0004] Moreover, in the prior art, hydraulic cylinders are provided at both ends of the drum, and the lifting of the drum is achieved by the extension or shortening of the hydraulic cylinders, with a simple structure. However, during use, since the equipment adopts single-sided drive, the fixed end of the hydraulic cylinder on one side is fixed to the frame, and the movable end is fixed to the transmission case; the fixed end of the hydraulic cylinder on the other side is fixed to the frame, and the movable end is directly connected to the side plate of the drum. During use, due to the large weight of the transmission case and to keep the drum always in a horizontal state, it is necessary to ensure that the two hydraulic cylinders lift synchronously. However, due to the large weight difference at both ends, the accuracy requirements for the hydraulic components are very high, imported components need to be used, the cost is very high, and the cleanliness requirements for the hydraulic oil are also very high. In addition, the operating environment of this equipment is complex, and the hydraulic oil needs to be replaced relatively frequently, further increasing the cost. Moreover, when mixing sea mud, due to the high water content and large viscosity of the sea mud, the resistance encountered by the drum during rotation increases, and it is extremely easy for the two ends of the drum to be unbalanced in force when lifting, resulting in the drum tilting. Once the drum tilts, the gear shaft connecting the drum and the gearbox will be damaged or even broken, directly affecting the service life of the equipment. And in some extreme working conditions, such as when the sea mud pile is huge, since the mixing equipment cannot automatically adjust the height of its own equipment, it may cause the mixing equipment to malfunction.

[0005] Therefore, there is an urgent need in the art for a high-power mixing equipment that can adjust the overall lifting of the equipment, ensure the service life of the equipment, mix sea mud in accordance with requirements according to the characteristics of sea mud, and reduce costs.

[0015] Preferably, one overall lifting assembly is symmetrically arranged on each side of the arched frame. The overall lifting assembly includes two lifting hydraulic cylinders, a positioning inner cylinder, and a guiding outer cylinder. The lifting hydraulic cylinders are connected to the control device. The guiding outer cylinder is slidably sleeved around the periphery of the positioning inner cylinder. The positioning inner cylinder is vertically and fixedly connected to the crawler support.

[0019] Preferably, climbing ladders are arranged on both sides of the arched frame.

[0020] The present invention has achieved the following beneficial technical effects compared with the prior art:

[0021] 1. For the on-site mobile mixing equipment for making soil from marine mud provided by the present invention, each mixing claw array is bent towards the middle of the cylinder body, so that each mixing claw array spirally winds around the cylinder body. When the mixing drum rotates, the spirally arranged mixing claws can throw the marine mud from both sides to the middle. After the marine mud free-falls, it becomes a pile, avoiding excessive dispersion after being thrown up. Due to the high viscosity of the marine mud, the mixing claws are set in a shape with an upper bend. After multiple tests and certifications, the spiral lift angle is set to 15° - 17°, and the axial distance between every two adjacent mixing claws in the same mixing claw array is 5 - 10 times the required particle size of the mixed marine mud, so that the crushing requirement of the particle size of the mixed marine mud can be met when turning over and throwing the marine mud, and the turning over and throwing effect of the marine mud is better.

[0022] 2. For the transmission component provided by the present invention, when mixing the marine mud, the marine mud has high viscosity and is not easy to separate, and the resistance generated on the drum is large, that is, a transmission component capable of transmitting high power is required to drive the drum to rotate. By setting a power distribution box and a gear box, the structure is compact, and gear shaft transmission is adopted. The power generated by the engine is distributed through the gears in the power distribution box. Compared with the prior art using a transmission shaft, the connection structure of the transmission component of this equipment is strong and not prone to failure. Even when transmitting a large force, it will not cause wear and fracture of the gear shaft, ensuring the service life of the transmission components and reducing the cost. Moreover, by setting a hydraulic clutch, when the hydraulic clutch is closed, the transmission component operates normally, driving the mixing drum to rotate for turning over and mixing the marine mud. When the hydraulic clutch is disengaged, the transmission component cannot operate and the mixing drum cannot rotate, ensuring safety during non-operation. And the hydraulic clutch device can slip, playing a buffering role, protecting the transmission parts in this equipment and ensuring the service life of the transmission parts.

[0023] 3. The overall lifting component provided by the present invention can lift or lower the mixing drum and the arched frame as a whole. In existing mixing equipment, only the mixing drum can be lifted, or neither can be automatically lifted. Then, in extreme working conditions, due to the high viscosity of the sea mud, when the sea mud pile after mixing and turning over is high enough, the existing mixing equipment will be trapped in place and unable to continue operating. However, the overall lifting component in this equipment overcomes this problem. When such extreme working conditions occur during the equipment's movement, it can lift the arched frame and the drum as a whole, cross over the sea mud pile, or turn over from the vertex of the sea mud pile, ensuring the normal construction of the equipment. In addition, due to the high viscosity of the sea mud, which generates a large resistance to the drum, uneven forces at both ends of the drum during the process of turning over the sea mud will cause the gear shaft between the drum and the transmission structure to break. The overall lifting component in this equipment enables the arched frame and the mixing drum to be lifted and lowered simultaneously, and the mixing drum always remains horizontal. Even if the arched frame is skewed due to the uneven road surface at the sea mud construction site or uneven resistance of the sea mud to the drum, the transmission shaft between the mixing drum and the arched frame will be skewed along with the arched frame, but the angle between the mixing drum and the transmission shaft will not change at all, no bending force will occur, and the phenomenon of damaging the transmission shaft will not occur, ensuring the service life of the transmission shaft and reducing costs.

[0024] 4. The on-site mobile mixing equipment for sea mud soil formation provided by the present invention adopts a crawler walking device, with a simple transmission structure, realizing on-site operation of mixing and solidifying sea mud and the mobility of the equipment. Due to the high viscosity of the sea mud, when mixing the sea mud, a high-power transmission component transmits greater power to drive the mixing claws on the mixing drum to grab the sea mud and turn it over backward. In extreme working conditions, the overall lifting component can be used to lift the equipment as a whole to cross over the sea mud pile. Each component in this equipment cooperates with each other and works together to realize the mixing of high-viscosity sea mud and ensure the service life of the equipment.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The present invention provides an on-site mobile mixing equipment for making soil with sea mud, as Figures 1-7As shown in the figure, it includes an arched frame 1, a mixing drum 2, two symmetrically arranged traveling assemblies, a transmission assembly, two symmetrically arranged integral lifting assemblies, and a control device. One traveling assembly is installed on each side of the arched frame 1, and the traveling assembly can drive the arched frame 1 to travel. A cab 3 is arranged above the arched frame 1, and the control device is arranged in the cab 3. The mixing drum 2 is installed inside the arched frame 1. One end of the mixing drum 2 is fixedly connected to the transmission assembly, and the other end of the mixing drum 2 is rotatably connected to the arched frame 1. Both the transmission assembly and the traveling assembly are connected to the control device. The integral lifting assembly is connected to the arched frame 1 and can lift the arched frame 1 and the mixing drum 2 integrally. The transmission assembly includes a power distribution box 10 and a gear box 11 with gear transmission. The input shaft of the power distribution box is connected to the engine, the engine is connected to the control device, and the gear box 11 is connected to the mixing drum 2.

[0037] Specifically, after the operator enters the cab 3, by operating the control device, the traveling assembly is controlled to drive the entire equipment to travel at the solidification site, and the transmission assembly is controlled to transmit power to the mixing drum 2 to drive the mixing drum 2 to rotate, so as to realize the turning and mixing of the sea mud at the solidification site. Due to the high viscosity of the sea mud, when mixing the sea mud, high-power power is transmitted through the transmission assembly, and gear transmission is used instead of the traditional transmission shaft transmission, reducing the wear and replacement of the transmission shaft and ensuring the service life of the transmission shaft; the transmission assembly drives the mixing claws 33 on the mixing drum 2 to grab the sea mud and turn it over backward. In extreme working conditions, the equipment can be integrally lifted by the integral lifting assembly to cross the sea mud pile, reducing the situation where the drum transmission shaft is damaged due to uneven forces at both ends of the mixing drum and ensuring the service life of the components. Each component in this equipment cooperates with each other and works together to realize the mixing of high-viscosity sea mud and ensure the service life of the equipment.

[0038] A plurality of mixing claw arrays are arranged on the outer surface of the cylinder body of the mixing drum 2, and each mixing claw array is bent toward the middle of the cylinder body. The axial distance between every two adjacent mixing claws 33 in the same mixing claw array is 5-10 times the required particle size of the mixed sea mud.

[0039] Specifically, the mixing claw arrays on the outer surface of the mixing drum 2 are evenly arranged around the cylinder body and form a spiral shape, so that the sea mud missed by the mixing claws in the previous mixing claw array is caught and turned over by the mixing claws 33 in the next mixing claw array, and the sea mud is concentrated and thrown toward the middle. The end of the mixing claw 33 is set in a bent shape, which is beneficial to breaking large pieces of sea mud and can gather the sea mud like a rake, and can better grasp the sea mud for mixing. In addition, through multiple tests and verifications, it is obtained that the axial distance between every two adjacent mixing claws 33 in the same mixing claw array is 5-10 times the required particle size of the mixed sea mud, which can meet the crushing requirements of the particle size of the mixed sea mud when turning over the sea mud and has a better turning effect on the sea mud.

[0040] In this embodiment, the angle between the straight line where the mixing claw array bent towards the middle of the cylinder body and the central axis of the mixing drum 2 is the spiral lift angle θ, and the range of the spiral lift angle θ is 15 degrees - 17 degrees. Generally speaking, the angle range of the spiral lift angle will be adjusted accordingly according to the requirements of the particle size of the mixed sea mud. The mixing claw array is set to 5 - 6 groups, and two adjacent mixing claw arrays are arranged staggeredly. Each mixing claw array includes a number of mixing claws 33 arranged at intervals in sequence. One end of the mixing claw 33 is vertically and fixedly connected to the mixing drum 2, and the other end of the mixing claw 33 is bent. Moreover, the mixing claws 33 at the corresponding positions on the two symmetric sides of the mixing claw array bent towards the middle of the cylinder body are bent in opposite directions. Using the mixing claws with this structure can scoop up the sea mud more effectively and meet the crushing requirements of the particle size of the mixed sea mud.

[0041] In this embodiment, a walking component is symmetrically connected to each side of the arched frame 1, and this walking component is a crawler walking component. The crawler walking component includes a crawler support 4, and the crawler support 4 is fixedly installed on the side of the arched frame 1 by bolts. The front end of the crawler support 4 is equipped with a crawler drive sprocket 5 and a crawler drive device. The crawler drive device is a hydraulic motor 6, and the hydraulic motor 6 is connected to the crawler drive sprocket 5 and is used to provide power for the crawler drive sprocket 5. The rear end of the crawler support 4 is equipped with a crawler idler 7 to adjust the tightness of the crawler 9, and several crawler carrier rollers 8 are installed in the middle of the crawler support 4 to support the crawler 9. The crawler drive sprocket 5 and the crawler idler 7 are meshed with the crawler 9 on the outside, and the crawler drive device is connected to the control device. By controlling the rotation of the hydraulic motor 6 through the control device, the movement of the crawler drive sprocket 5 is driven, thereby driving the rotation of the crawler 9, enabling the mixing equipment to move, ensuring that the mixing equipment can construct and mix sea mud at the solidification site, realizing the mobility of the equipment, saving costs and time compared with the method of transporting sea mud by using a mixing station in the prior art.

[0042] In this embodiment, one end of the input shaft 12 of the power distribution box is fixedly connected to the engine, and the other end of the input shaft 12 of the power distribution box is connected to the power distributor 13 inside the power distribution box 10. A distribution box gear 14 and several additional power gears 15 are arranged inside the power distribution box 10. Both the distribution box gear 14 and the several additional power gears 15 are meshed with the gears on the input shaft 12 of the power distribution box. Inside the gearbox 11, an upper gear 16, four intermediate gears 17, and a lower gear 18 are meshed and connected in sequence from top to bottom. The gear shaft of the distribution box gear 14 shares a gear shaft with the gear shaft of the upper gear 16. The gear shaft of the lower gear 18 is fixedly connected to the mixing drum 2. The upper gear 16 and the four intermediate gears 17 are all fixedly installed on the corresponding gear shafts inside the gearbox 11. Each gear shaft is installed on the side wall of the gearbox 11 through a bearing. The several additional power gears 15 are fixedly installed on the corresponding gear shafts inside the power distribution box 10. Each gear shaft is installed on the side wall of the power distribution box 10 through a bearing.

[0043] In this embodiment, a power distributor first gear 19, a hydraulic clutch 20, and a power distributor second gear 21 are meshed and connected in sequence on the input shaft of the power distribution box from the input end to the output end. The power distributor first gear 19 is meshed with the distribution box gear 14. The power distributor second gear 21 is meshed with the additional power gear 15. The hydraulic clutch 20 is connected to a hydraulic valve 22, and the hydraulic valve 22 is connected to a control device.

[0044] Specifically, the transmission component provided by this equipment can transmit high-power power. By setting the power distribution box 10 and the gearbox 11 and adopting gear shaft transmission, the power generated by the engine is distributed through the power distributor 13 inside the power distribution box 10. The power distributor second gear 21 is meshed with two additional power gears 15 to transmit the power to additional devices such as oil pumps or air-conditioning compressors that require power. The power distributor first gear 19 is meshed with the distribution box gear 14. The distribution box gear 14 shares a gear shaft with the upper gear 16 of the gearbox 11. The rotation of the power distributor first gear 19 drives the rotation of the distribution box gear 14, which in turn drives the rotation of the shared gear shaft, and further drives the rotation of the upper gear 16 of the gearbox 11 to transmit the power to the gearbox 11. In the prior art, a universal drive shaft is used to transmit power. However, due to the high viscosity of the sea mud, a large amount of power is required for turning and mixing the sea mud. If the power is insufficient or the universal drive shaft is damaged, the mixing drum may get stuck in the sea mud and cannot rotate, and even pose a great safety hazard. By adopting gear transmission in the transmission component of this equipment, it replaces the universal drive shaft transmission, reduces the wear and fracture of the drive shaft, ensures the service life of the transmission components, and also achieves the technical effect of a compact structure.

[0045] In addition, by setting up the hydraulic clutch 20, the control device controls the "engagement" and "disengagement" of the hydraulic clutch 20 by controlling the hydraulic valve 22. When the hydraulic clutch 20 is "engaged", the transmission assembly operates normally, driving the mixing drum 2 to rotate and perform the turning, tossing and mixing operation on the sea mud. When the hydraulic clutch 20 is "disengaged", the transmission assembly cannot operate and the mixing drum 2 cannot rotate, ensuring safety during non-operation. Because in the non-working state, the mixing drum 2 cannot rotate. If there is a foreign object in front, the rotation of the mixing drum 2 will drive the turning of the foreign object, creating a safety hazard. At the same time, the rotation of the mixing drum 2 in the non-working state will increase the energy consumption of the mixing drum 2. In addition, since the hydraulic clutch 20 can be "engaged" and "disengaged", that is, it can slip, it has a certain impact resistance. Because when the load on the mixing drum 2 is very large, the hydraulic clutch device slips, playing a buffering role and protecting the transmission components in this equipment and ensuring the service life.

[0046] In this embodiment, an integral lifting assembly is respectively arranged on both sides of the arched frame 1. The integral lifting assembly includes two lifting hydraulic cylinders 23, a positioning inner cylinder 24 and a guiding outer cylinder 25. The lifting hydraulic cylinders 23 are connected to the control device. The guiding outer cylinder 25 is slidably sleeved around the periphery of the positioning inner cylinder 24. The positioning inner cylinder 24 is vertically and fixedly connected to the crawler support 4. The side end of the guiding outer cylinder 25 is fixedly connected to the arched frame. The cylinder barrel end of the lifting hydraulic cylinder 23 is fixedly connected to the arched frame 1, and the piston rod end of the lifting hydraulic cylinder 23 is fixedly connected to the inner side of the crawler support 4.

[0047] Specifically, the integral lifting assembly in this equipment can lift or lower the mixing drum 2 and the arched frame 1 as a whole. By controlling the lifting hydraulic cylinders 23, relative movement will occur between the piston rod end and the cylinder barrel end of the lifting hydraulic cylinder. The cylinder barrel end will drive the arched frame 1 to lift and lower along the positioning inner cylinder 24, and the lifting and lowering of the arched frame 1 will drive the lifting and lowering of the mixing drum 2. In the prior art, the mixing equipment can only lift the mixing drum 2. Due to the high viscosity of the sea mud, there will be particularly large sea mud piles at the operation site. When in the extreme working conditions, when the sea mud pile to be turned and tossed and the sea mud pile after turning and tossing are large enough to cause the entire equipment to stagnate, the integral lifting assembly in this equipment can drive the mixing drum and the arched frame to be lifted as a whole, so as to cross the sea mud pile and realize the continuous operation of the equipment.

[0048] In addition, in the prior art, the mixing equipment can only lift the mixing drum 2, and the levelness of the mixing drum 2 is required. However, the main transmission part of the mixing drum 2 is on one side of the arched frame 1. Coupled with the unknown load at the sea mud solidification site, the loads on both sides of the mixing drum 2 cannot be balanced. Therefore, bending force will occur on the transmission shaft of the mixing drum 2 and the transmission part, resulting in damage to the transmission shaft. The solution in the prior art is to set a synchronous valve. However, the synchronous valve has high requirements for the cleanliness of the hydraulic oil and requires frequent replacement of the hydraulic oil. Once the oil output at both ends of the synchronous valve is different, the mixing drum 2 cannot be lifted or lowered horizontally, and the same bending force will occur on the transmission shaft of the mixing drum 2 and the transmission part, damaging the transmission shaft. In the present equipment, the overall lifting assembly lifts the arched frame 1 and the mixing drum 2 simultaneously, and the mixing drum 2 always maintains a horizontal state. Even if the arched frame 1 is skewed, the mixing drum 2 and the transmission assembly connected to the mixing drum 2 will be skewed along with the skewing of the arched frame 1, but the angle between the mixing drum 2 and the transmission assembly will not change at all, and no bending force will occur, so the phenomenon of damaging the transmission shaft will not occur, ensuring the service life of the transmission shaft. Moreover, the present equipment no longer requires high-precision hydraulic oil and synchronous valves, and there is no need for frequent oil change, reducing the cost. Additionally, the four lifting hydraulic cylinders 23 on the crawler support 4 support the overall lifting of the mixing drum 2 and the arched frame 1, strengthening the supporting force for the equipment lifting compared to the original two lifting hydraulic cylinders.

[0049] In this embodiment, the overall lifting assembly further includes a horizontally connected transverse connecting plate 26 and a laterally connected lateral connecting plate 27. The positioning inner cylinder 24 is fixedly connected to the upper surface of the transverse connecting plate 26, and the lower end of the lateral connecting plate 27 is fixedly connected to the outside of the crawler support 4. By providing the transverse connecting plate 26 and the lateral connecting plate 27, the support for the positioning inner cylinder 24 is achieved.
