Description

Technical Field

[0001] This utility model relates to the technical field of sludge solidification devices, specifically an in-situ solidification treatment device for intertidal sludge. Background Technology

[0002] The intertidal zone is the area between the beach and the sea. Here, the seawater flows very slowly, resulting in thick layers of silty sediment. After the tide recedes, locals and tourists like to gather in large areas of the intertidal zone. Because the intertidal zone is mostly composed of silty sediment, it is prone to collapses and other accidents. Therefore, it is necessary to solidify the intertidal silt. Silt solidification involves spreading a solidifying agent into the silt and then using a mixing device to stir it, allowing the solidifying agent to fully react with the silt and achieve the desired solidification effect.

[0003] However, in the silt solidification process, due to the large amount of water accumulation in the intertidal zone, a large amount of solidifying agent is required to achieve the solidification effect. However, a large amount of solidifying agent is prone to accumulation and poor integration with the silt, resulting in a less obvious solidification effect and a waste of solidifying agent. Utility Model Content

[0004] The purpose of this invention is to provide an in-situ solidification treatment device for intertidal silt to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an in-situ solidification treatment device for intertidal silt, comprising a gantry frame and a moving device, wherein a telescopic device is provided on the gantry frame, a connecting box is provided below the telescopic device, a stirring device is provided below the connecting box, and a water storage device is fixedly provided on the side wall of the gantry frame.

[0006] The connecting box is equipped with a storage box, and the top of the storage box has a feed inlet. The connecting box is equipped with a water inlet pipe located below the connecting box. A self-priming pump is installed on the water inlet pipe. A hose is connected to the water outlet of the water inlet pipe. The end of the hose away from the water inlet pipe is connected to a water storage device. A branch pipe is installed on the water inlet pipe, and a water pump is installed on the branch pipe.

[0007] A mixing pipe with its water outlet located below the connecting box is provided on the side wall of the storage tank. A nozzle is connected to the water outlet of the mixing pipe. An air pump is provided on the pipe of the mixing pipe near the storage tank. The end of the branch pipe away from the water suction pipe is connected to the mixing pipe.

[0008] As a preferred embodiment, the water inlet end of the water suction pipe located below the connecting box is equipped with a filter screen.

[0009] As a preferred embodiment, a fixing clip is provided on the side wall of the water suction pipe, and a humidity detector is fixedly held in the fixing clip.

[0010] As a preferred embodiment, the mobile device includes a connecting frame and casters, with the connecting frame located below the gantry and the casters located below the connecting frame.

[0011] As a preferred embodiment, the telescopic device includes a hydraulic cylinder and a piston rod. The hydraulic cylinder is mounted on the gantry frame, and the piston rod is positioned below the hydraulic cylinder. The end of the piston rod away from the hydraulic cylinder is fixedly connected to the top surface of the connecting box.

[0012] As a preferred embodiment, the stirring device includes a stirring arm disposed below the connecting box, two stirring heads disposed at the lower end of the stirring arm, a rotating head disposed at the output end of the stirring head, a fixed plate disposed on the end face of the stirring head, and a plurality of stirring rods disposed on the outer surface of the fixed plate.

[0013] As a preferred embodiment, multiple blades are equidistantly arranged on the outer wall of the rotating head.

[0014] As a preferred embodiment, a hydraulic motor is fixedly installed inside the connecting box, and the hydraulic motor is connected to the upper end of the stirring arm.

[0015] As a preferred embodiment, the water storage device includes a water tank fixed to the side wall of the gantry, and a drain pipe is provided at the end of the water tank away from the gantry.

[0016] As can be seen from the technical solution provided by this utility model above, the beneficial effects of the in-situ solidification treatment device for intertidal silt provided by this utility model are:

[0017] In this invention, when solidifying silt, a self-priming pump is first started to draw seawater from the intertidal zone into the storage device through the suction pipe. This prevents excessive seawater residue in the intertidal zone, reducing the amount of solidifying agent required to achieve the desired silt solidification effect. This facilitates the silt solidification process. When spraying the solidifying agent, an air pump is started, and air carries the solidifying agent into the mixing pipe. Subsequently, a portion of the seawater from the suction pipe is fed into the mixing pipe through a branch pipe, allowing the solidifying agent and some seawater to undergo preliminary mixing within the mixing pipe. After preliminary mixing, the mixture is sprayed into the silt through the nozzle. The stirring device then completely mixes the solidifying agent with the silt, preventing a large amount of solidifying agent from accumulating in the silt, improving the solidification effect of the intertidal zone, and avoiding waste of the solidifying agent.

[0027] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-4 As shown, this utility model embodiment provides an in-situ solidification treatment device for intertidal silt, including a gantry frame 1 and a moving device 2. A telescopic device 3 is provided on the gantry frame 1, a connecting box 4 is provided below the telescopic device 3, a stirring device 5 is provided below the connecting box 4, and a water storage device 6 is fixedly provided on the side wall of the gantry frame 1.

[0029] The connecting box 4 is equipped with a storage box 41. The top of the storage box 41 is provided with a feed inlet 411. The connecting box 4 is equipped with a water inlet pipe 42 located below the connecting box 4. A self-priming pump 422 is provided on the water inlet pipe 42. A hose 43 is connected to the water outlet of the water inlet pipe 42. The end of the hose 43 away from the water inlet pipe 42 is connected to the water storage device 6. A branch pipe 44 is provided on the water inlet pipe 42. A water pump 441 is provided on the branch pipe 44.

[0030] The storage tank 41 is provided with a mixing pipe 45 with the water outlet located below the connecting box 4. The water outlet of the mixing pipe 45 is connected to a nozzle 451. An air pump 46 is provided on the pipe of the mixing pipe 45 near the storage tank 41. The end of the branch pipe 44 away from the suction pipe 42 is connected to the mixing pipe 45.

[0031] A movable device 2 is installed below the gantry frame 1 to move the entire curing device, facilitating its transport. A telescopic device 3 controls the vertical movement of the connecting box 4, causing the components and stirring device 5 inside the connecting box 4 to move vertically. The telescopic device 3 lowers the connecting box 4, allowing the lower end of the suction pipe 42 to penetrate into the intertidal zone. Then, the self-priming pump 422 is activated to draw seawater from the intertidal zone into the storage device 6 through the suction pipe 42 and hose 43, preventing excessive seawater residue in the intertidal zone and reducing the amount of curing agent required to achieve sludge curing. This facilitates subsequent sludge curing operations. Due to the hose 43, seawater can also smoothly enter the storage device 6 through the suction pipe 42 when the connecting box 4 moves vertically. After the excess seawater is absorbed, the inlet 411 is used to introduce curing agent into the storage tank 41 for storage. The air pump 46 is then activated, and the air pump 46 inputs... The surface of the end has a through hole to facilitate air entering the air pump 46. As the air enters the air pump 46 through the through hole, it also carries the curing agent from the storage tank 41 into the air pump 46, and then into the mixing pipe 45. While the air pump 46 is working, the water pump 441 sends a portion of the seawater from the suction pipe 42 through the branch pipe 44 into the mixing pipe 45, using local materials and reducing water waste. This allows the curing agent and a portion of the seawater to be initially mixed in the mixing pipe 45. Compared to directly sending seawater into the storage tank 41 to mix with all the curing agent, this method allows for immediate use and avoids waste of the curing agent. After the curing agent and seawater are initially mixed, they are sprayed into the silt through the nozzle 451. The stirring device 5 then completely mixes the curing agent with the silt, preventing a large amount of curing agent from accumulating in the silt, improving the curing effect of the intertidal zone, and avoiding waste of the curing agent.

[0032] like Figure 3 As shown, the water inlet end of the water suction pipe 42 located below the connecting box 4 is equipped with a filter screen 421.

[0033] A filter screen 421 is installed at the water inlet end of the suction pipe 42 to prevent anything other than seawater from entering the suction pipe 42 and causing blockage, thereby improving the water absorption effect.

[0034] like Figure 3 As shown, a fixing clip 47 is provided on the side wall of the water suction pipe 42, and a humidity detector 48 is clamped and fixed inside the fixing clip 47.

[0035] The fixing clamp 47 is used to hold and fix the humidity detector 48. The humidity detector 48 is used to measure the humidity of the intertidal zone. When the humidity in the intertidal zone is too high, the excess seawater in the intertidal zone is introduced into the water storage device 6 through the water suction pipe 42 and the hose 43 to prevent the seawater in the intertidal zone from being too much and affecting the curing effect.

[0036] like Figure 2 As shown, the mobile device 2 includes a connecting frame 21 and a universal wheel 22. The connecting frame 21 is located below the gantry frame 1, and the universal wheel 22 is located below the connecting frame 21.

[0037] The caster wheel 22 allows the device to move in any direction, and the connecting frame 21 is used to connect the gantry frame 1 and the caster wheel 22.

[0038] like Figure 2 As shown, the telescopic device 3 includes a hydraulic cylinder 31 and a piston rod 32. The hydraulic cylinder 31 is mounted on the gantry frame 1, and the piston rod 32 is mounted below the hydraulic cylinder 31. The end of the piston rod 32 away from the hydraulic cylinder 31 is fixedly connected to the top surface of the connecting box 4.

[0039] When it is necessary to move the connecting box 4 and the stirring device 5 up and down, the hydraulic cylinder 31 is activated. The hydraulic cylinder 31 drives the piston rod 32 to move up and down, thereby driving the connecting box 4, the various components inside the connecting box 4 and the stirring device 5 to move up and down.

[0040] like Figure 4 As shown, the stirring device 5 includes a stirring arm 51 disposed below the connecting box 4. The lower end of the stirring arm 51 is provided with two stirring heads 52. The output end of the stirring head 52 is provided with a rotating head 53. The end face of the stirring head 52 is provided with a fixed plate 54. The outer surface of the fixed plate 54 is provided with multiple stirring rods 56.

[0041] Two stirring heads 52 are provided at the lower end of the stirring arm 51, which can increase the stirring range of intertidal silt. The rotation of the stirring head 52 drives the rotating head 53 and the fixed plate 51 to rotate, which in turn causes the stirring rod 56 to rotate, so as to fully mix the silt and the solidifying agent and improve the stirring effect of the stirring device 5.

[0042] like Figure 4 As shown, multiple blades 55 are equidistantly arranged on the outer wall of the rotating head 53.

[0043] The addition of multiple blades 55 equidistantly arranged on the outer wall of the rotor 53 further enhances the mixing effect of the device, ensuring thorough mixing of the curing agent and sludge, and further shortening the sludge curing time.

[0044] like Figure 4 As shown, a hydraulic motor 57 is fixedly installed inside the connecting box 4, and the hydraulic motor 57 is connected to the upper end of the stirring arm 51.

[0045] The hydraulic motor 57 is used to provide stirring power for the stirring arm 51. At the same time, the hydraulic motor is placed in the connecting box 4, which helps to protect the hydraulic motor 57 and prevent damage to the hydraulic motor 57 during operation.

[0046] like Figure 2 As shown, the water storage device 6 includes a water storage tank 61 fixed on the side wall of the gantry frame 1, and a drain pipe 62 is provided at the end of the water storage tank 61 away from the gantry frame 1.

[0047] The water storage tank 61 is fixed on the gantry frame 1 and is used to store excess seawater in the intertidal zone sucked up by the suction pipe 42. When the device is moved to a suitable drainage location, the seawater will be discharged from the drain pipe 62.

[0048] The working principle of this embodiment is as follows: Hydraulic cylinder 31 is activated, driving piston rod 32 downwards, which in turn moves connecting box 4, its components, and stirring device 5 downwards, causing the lower end of suction pipe 42 to penetrate into the residual seawater in the intertidal zone. Then, self-priming pump 422 is activated, drawing seawater from the intertidal zone through suction pipe 42 and hose 43 into water storage device 6 for storage, preventing excessive seawater residue in the intertidal zone and facilitating subsequent silt solidification. Next, air pump 46 is activated. Air pump 46 has a through-hole on its input end surface, allowing air to enter the pump. Simultaneously, as air enters air pump 46 through the through-hole... The curing agent is introduced into the air pump 46 and then into the mixing pipe 45. While the air pump 46 is working, the water pump 441 introduces a portion of the seawater from the suction pipe 42 into the mixing pipe 45 through the branch pipe 44, allowing the curing agent and a portion of the seawater to undergo preliminary mixing in the mixing pipe 45. After the preliminary mixing is completed, the mixture is sprayed into the silt through the nozzle 451. The hydraulic motor 57 drives the stirring arm 51 to rotate, which in turn drives the stirring head 52 to rotate, thereby driving the rotating head 53, the fixed plate 54, and the blade 55 to rotate, completely mixing the curing agent with the silt. This prevents a large amount of curing agent from accumulating in the silt, improves the curing effect of the intertidal zone, and avoids the waste of curing agent.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
