Description

Technical Field

[0001] This utility model relates to the field of mud solidification treatment technology, and in particular to a mud solidification treatment mixing device. Background Technology

[0002] With the rapid development of the national construction, transportation, and petroleum industries, buildings are becoming increasingly taller, and the mileage of highways, high-speed railways, and subways is expanding. The number of oil and gas wells is also increasing. Therefore, the widespread use of bored piles, diaphragm walls, shield tunneling, and well drilling for oil extraction generates large amounts of waste mud. Untreated waste mud cannot be directly stockpiled, transported, or used in engineering projects. It not only occupies significant space resources and incurs high transportation costs, but also easily accumulates pollutants, leading to leakage and runoff, causing water and soil pollution. Furthermore, indiscriminate stockpiling can cause slope slippage, foundation settlement, and other safety hazards, failing to meet environmental emission and engineering construction standards. Therefore, the industry widely adopts solidification treatment technology to improve and treat waste mud.

[0003] A waste mud solidification treatment mixing device with Chinese patent publication number CN221522361U, according to its description, has a mixing component fixedly installed inside the mixing device box. After the mud solidification treatment is completed, it is discharged through the bottom outlet. The mixing component located inside the mixing device box will block the falling solidified mud. At the same time, the outlet is relatively small, which makes it very easy to get blocked during discharge, thus increasing the difficulty of discharge.

[0004] Therefore, it is necessary to provide a new mud solidification treatment mixing device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mud solidification treatment mixing device.

[0006] The mud solidification treatment mixing device provided by this utility model includes a frame, a treatment cylinder for treating sludge is provided inside the frame, and a sealing component is provided at the bottom of the treatment cylinder; The processing cylinder is equipped with a rotating stirring rod inside. A connecting ring is fixedly installed at the bottom end of the stirring rod, and multiple staggered stirring blades are fixedly installed at the top of the connecting ring. The top of the frame is provided with a top frame, and a vertical hydraulic cylinder is fixedly connected between the top frame and the frame. The bottom of the top frame is rotatably connected to the top of the stirring rod through a bearing. The bottom end of the vertical hydraulic cylinder is fixedly connected to the frame, and the top end of the vertical hydraulic cylinder is fixedly connected to the top frame.

[0007] Preferably, the top and bottom of the processing cylinder are both open structures, and a retaining ring is fixedly installed at the bottom of the processing cylinder.

[0008] Preferably, the sealing assembly includes a fixing frame, which is fixedly connected to the frame body. The fixing frame has a slidably connected sealing disc, and the side wall of the sealing disc abuts against the side wall of the retaining ring.

[0009] Preferably, a horizontal hydraulic cylinder is installed between the sealing disc and the fixing frame, the output end of the horizontal hydraulic cylinder is fixedly connected to the side wall of the sealing disc, and the fixed end of the horizontal hydraulic cylinder is fixedly connected to the fixing frame.

[0010] Preferably, the bottom of the fixing frame is provided with a guide groove, and a guide block that is slidably connected is inserted into the guide groove, and the bottom end of the guide block is fixedly connected to the top of the sealing plate.

[0011] Preferably, a motor for driving the stirring rod is fixedly installed on the top of the top frame, and symmetrically distributed guide rods are fixedly installed on both sides of the bottom of the top frame, with the bottom ends of the guide rods extending to the bottom of the frame.

[0012] Preferably, the top of the frame is provided with a guide hole, and the inner wall of the guide hole abuts against and is slidably connected to the outer wall of the guide rod.

[0013] Compared with related technologies, the mud solidification treatment mixing device provided by this utility model has the following beneficial effects: 1. In the process of mixing, the vertical hydraulic cylinder can drive the mixing rod and mixing blades to move vertically through the top frame. This allows the mixing blades to mix the sludge inside the processing cylinder from bottom to top, thereby improving the overall mixing of the sludge. After mixing is completed, the mixing components can also be positioned above the sludge, thus avoiding the mixing blades being located inside the solidified sludge and causing obstruction to subsequent discharge. 2. The bottom of the processing cylinder of this utility model is set as an open structure. After the curing is completed, when the sealing plate is moved outward, the open processing cylinder can make the sludge fixed inside discharge more smoothly downward, thus reducing the probability of blockage during discharge. 3. During material discharge, the present invention can control the vertical hydraulic cylinder to retract, thereby driving the stirring blades and connecting ring to move downward. The moving connecting ring and stirring blades will squeeze the top of the fixed sludge, and the applied squeezing force can also help improve the sludge discharge effect. At the same time, the connecting ring that abuts against the inner wall of the treatment cylinder can also scrape the inner wall of the treatment cylinder, thereby making the sludge discharge cleaner and reducing sludge residue.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] Please see Figures 1 to 5 The present invention provides a mud solidification treatment mixing device, which includes a frame 1, a treatment cylinder 2 for treating sludge inside the frame 1, and a sealing component 3 at the bottom of the treatment cylinder 2.

[0019] In the embodiments of this utility model, please refer to Figures 1 to 5 The processing cylinder 2 is equipped with a rotating stirring rod 4 inside. A connecting ring 42 is fixedly installed at the bottom end of the stirring rod 4, and multiple staggered stirring blades 41 are fixedly installed at the top of the connecting ring 42. The top of the frame 1 is equipped with a top frame 5. A vertical hydraulic cylinder 6 is fixedly connected between the top frame 5 and the frame 1. The bottom of the top frame 5 is rotatably connected to the top end of the stirring rod 4 through a bearing. The bottom end of the vertical hydraulic cylinder 6 is fixedly connected to the frame 1, and the top end of the vertical hydraulic cylinder 6 is fixedly connected to the top frame 5.

[0020] It should be noted that during the mixing process, the vertical hydraulic cylinder 6 can drive the mixing rod 4 and the mixing blade 41 to move vertically through the top frame 5. This allows the mixing blade 41 to stir the sludge inside the processing cylinder 2 from bottom to top, thereby improving the overall mixing of the sludge by the mixing blade 41. After the mixing is completed, the mixing component can also be positioned above the sludge, thus avoiding the mixing blade 41 being located inside the solidified sludge and causing obstruction to subsequent discharge. During discharge, the working vertical hydraulic cylinder 6 can drive the stirring blades 41 and the connecting ring 42 to move downwards. The moving connecting ring 42 and stirring blades 41 will squeeze the top of the fixed sludge. The applied squeezing force can make the sludge discharge downwards more smoothly, thereby helping to improve the sludge discharge effect. At the same time, the connecting ring 42, which abuts against the inner wall of the treatment cylinder 2, can also scrape the inner wall of the treatment cylinder 2, thus making the sludge discharge cleaner and reducing sludge residue.

[0021] In the embodiments of this utility model, please refer to Figures 1 to 5 The top and bottom of the processing cylinder 2 are both open structures, and a retaining ring 21 is fixedly installed at the bottom of the processing cylinder 2. The sealing assembly 3 includes a fixing frame 31, which is fixedly connected to the frame body 1. A sealing disc 33 is provided inside the fixing frame 31 and is slidably connected. The side wall of the sealing disc 33 abuts against the side wall of the retaining ring 21. A horizontal hydraulic cylinder 32 is mounted between the sealing disc 33 and the fixing frame 31. The output end of the horizontal hydraulic cylinder 32 is fixedly connected to the side wall of the sealing disc 33, and the fixed end of the horizontal hydraulic cylinder 32 is fixedly connected to the fixing frame 31.

[0022] It should be noted that by setting the bottom of the treatment cylinder 2 to an open structure, the bottom of the treatment cylinder 2 can be completely exposed after the sealing plate 33 is removed from the bottom of the treatment cylinder 2. This can improve the discharge specifications of the treatment cylinder 2 in the later stage, thus making the discharge of solidified sludge smoother. By abutting against the side wall of the sealing disc 33 and the retaining ring 21, the sealing disc 33 can seal the bottom of the treatment cylinder 2, thereby preventing the sludge from leaking from the bottom of the treatment cylinder 2 when adding liquid sludge, thus allowing the sludge to be smoothly mixed and solidified with the solidifying agent in the later stage.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 5 The bottom of the fixing frame 31 is provided with a guide groove 311, and a guide block 312 is inserted inside the guide groove 311. The bottom end of the guide block 312 is fixedly connected to the top of the sealing plate 33.

[0024] It should be noted that: through the sliding connection between the guide block 312 and the guide groove 311, during use, the guide block 312 can improve the lateral support strength of the horizontal hydraulic cylinder 32 by resisting the force between it and the guide groove 311, thereby enabling the sealing disc 33 to stably seal the bottom of the treatment cylinder 2, and avoiding the phenomenon of bending damage to the horizontal hydraulic cylinder 32 caused by the gravity of the sludge in the treatment cylinder 2.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 5 The top of the top frame 5 is fixedly equipped with a motor that drives the stirring rod 4. The bottom sides of the top frame 5 are fixedly equipped with symmetrically distributed guide rods 51, and the bottom end of the guide rods 51 extends to the bottom of the frame 1. The top of the frame 1 is provided with a guide hole 11, and the inner wall of the guide hole 11 abuts against and slides with the outer wall of the guide rod 51.

[0026] It should be noted that: through the sliding connection between the guide rod 51 and the guide hole 11, the guide rod 51 can increase the support strength of the vertical hydraulic cylinder 6 by resisting the horizontal force of the guide hole 11 during use, thereby improving the working stability of the vertical hydraulic cylinder 6.

[0027] The working principle of the mud solidification treatment mixing device provided by this utility model is as follows: When using this solidification treatment mixing device, the sludge and solidifying agent to be treated can be added to the inside of the treatment cylinder 2 in sequence. After the sludge and solidifying agent are added, the motor can be controlled to drive the stirring rod 4 and the stirring blade 41 to rotate. The rotating stirring blade 41 can stir and mix the sludge and solidifying agent in the treatment cylinder 2. Furthermore, during the mixing process, the vertical hydraulic cylinder 6 can be controlled to work. The working vertical hydraulic cylinder 6 will drive the mixing rod 4 and the mixing blade 41 to move vertically through the top frame 5. This allows the mixing blade 41 to stir the sludge inside the processing cylinder 2 from bottom to top. Since the mixing blade 41 is staggered, the mixing of the sludge by the mixing blade 41 can be improved, thereby improving the reaction effect between the sludge and the solidifying agent. By driving the stirring blades 41, after the sludge is stirred, the stirring blades 41 can be removed from the sludge. Thus, when the stirred sludge is allowed to settle and solidify, the stirring blades 41 can be prevented from being wrapped by the solidified sludge, thus avoiding blockage of the sludge's falling trajectory. After the sludge has solidified, the horizontal hydraulic cylinder 32 can be controlled to work. The working horizontal hydraulic cylinder 32 will drive the sealing plate 33 to move horizontally. When the sealing plate 33 moves out from the bottom of the processing cylinder 2, the obstruction to the bottom of the processing cylinder 2 can be removed, and the bottom of the processing cylinder 2 will be exposed. During the feeding process, the vertical hydraulic cylinder 6 can also be controlled to drive the stirring blade 41 and the connecting ring 42 to move downward. The moving stirring blade 41 and the connecting ring 42 will squeeze the top of the solidified sludge, thereby increasing the downward force of the sludge. Therefore, the sludge can fall and be discharged more smoothly. During the discharge process, the connecting ring 42, which abuts against the inner wall of the processing cylinder 2, can also scrape and clean the sludge on the inner wall of the processing cylinder 2, thereby avoiding the residue of sludge inside the processing cylinder 2. Therefore, the discharge of sludge can be more thorough.

[0028] In this invention, both the horizontal hydraulic cylinder 32 and the vertical hydraulic cylinder 6 are connected to a standard hydraulic system via external pipelines to achieve their extension and retraction control. The specific setup of this hydraulic system is conventional technology in the field. In addition, the circuit involved in this invention is controlled by a PLC controller. The PLC sends control signals to the motor driver and the hydraulic solenoid valve in sequence according to a preset program to drive the motor and the hydraulic cylinder. The circuits and controls involved are all existing technologies and will not be described in detail here.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
