Description

Technical Field

[0001] This utility model belongs to the technical field of mud solidification treatment equipment, and specifically relates to a mud solidification treatment equipment. Background Technology

[0002] As environmental protection requirements for construction projects continue to rise across the country, the mud generated from pile foundation projects is difficult to transport directly by vehicle, and it is prone to spillage during transportation, polluting the environment. Special treatment is required to separate the solid and liquid components and solidify the mud, making it easier to transport and also allowing it to be recycled as soil.

[0003] Currently, the mud generated during bored pile construction is pumped to the screening layer via an external pump. The filtered mud falls into the mixing chamber, where lime powder is added through the upper feed inlet. After thorough mixing, it is pumped into the solidification mechanism. The mud adheres to the surface of the filter plate and is then pressed by jacks to solidify into mud blocks that fall off. However, existing mud solidification equipment has the following drawbacks: lime powder is usually manually sprinkled into the mixing chamber, which is slow and cannot be added intermittently, affecting the uniformity of mixing. Therefore, a mud solidification treatment device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a mud solidification treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mud solidification treatment device, comprising a mud mixing chamber, a filter screen fixedly connected to the inner wall of the mud mixing chamber, a conveying pipe communicating with the interior of the mud mixing chamber located on the left side wall near the front side wall, an external pipe communicating with the interior of the mud mixing chamber located on the right side wall near the rear side wall, two symmetrically distributed mixing shafts rotatably connected to the inner top wall of the mud mixing chamber, multiple mixing rods fixedly connected to the outer walls of both mixing shafts, the top of one mixing shaft extending to the top of the mud mixing chamber and connected to the output shaft of a motor, a feeding channel opening in the middle of the top of the mud mixing chamber, an intermittent feeding structure installed at the feeding channel; the intermittent feeding structure is used to intermittently feed lime powder into the mud mixing chamber.

[0006] In a preferred embodiment, the intermittent feeding structure includes a feeding hopper slidably connected at the feeding channel, and a baffle plate fixed to the top wall of the mud mixing chamber is provided in the middle of the feeding channel. The top of the baffle plate is flush with the bottom outlet of the feeding hopper.

[0007] In a preferred embodiment, sliders with a convex vertical cross-section are fixedly connected to both sides of the feeding hopper, and the sliders are slidably connected to the grooves opened in the inner wall of the feeding channel.

[0008] In a preferred embodiment, sprockets a are fixedly connected to the outer sides of both stirring shafts. The two sprockets a are connected to sprocket b via chain drive. The sprocket b is rotatably connected to the inner top wall of the mud mixing chamber via a rotating shaft. The top end of the rotating shaft extends to the top of the mud mixing chamber and is fixedly connected to a turntable. A push-pull rod is rotatably connected to the surface edge of the turntable, and the other end of the push-pull rod is rotatably connected to the outer side of the feeding hopper.

[0009] In a preferred embodiment, L-shaped guide rods are fixedly connected to both side walls of the feeding hopper, and C-shaped moving rods are slidably sleeved on the outer sides of the two L-shaped guide rods. A striking ball is fixedly connected to the top of each of the two C-shaped moving rods, and a roller is rotatably connected to the bottom of each of the two C-shaped moving rods. Guide seats are fixedly connected to the top of the mud mixing chamber on both sides of the middle part of the feeding channel, and the cross-section of each guide seat is an isosceles trapezoidal structure.

[0010] In a preferred embodiment, the opposite sidewalls of the two C-shaped moving rods are fixed to the L-shaped guide rod by S-shaped spring clips.

[0011] Compared with the prior art, the mud solidification treatment equipment provided by this utility model has at least the following beneficial effects:

[0012] In this invention, when using the slurry solidification treatment equipment, after adding the required lime powder to the feeding hopper, the motor is started to stir the slurry filtered by the filter screen. The action of sprocket a, chain, and sprocket b causes the stirring action to be combined with the rotation of the turntable connected to the shaft. The push-pull rod further causes the feeding hopper to move back and forth. When the bottom of the feeding hopper is in contact with the top of the baffle plate, the lime powder in the feeding hopper is intercepted and prevented from discharging. When the bottom of the feeding hopper... When the feed hopper moves to the front and rear sides of the baffle plate, the lime powder will fall into the mud mixing chamber, thus achieving intermittent feeding of lime powder and effectively ensuring the uniformity of mixing between mud and lime powder. Secondly, during the reciprocating back and forth movement of the feed hopper, due to the shape design of the guide seat and the setting of the rollers, the two C-shaped moving rods will move in opposite directions, and the rebound force of the S-shaped spring sheet after being squeezed and deformed will knock on the outer wall of the feed hopper, thus effectively preventing the lime powder from clogging in the feed hopper and affecting the feeding.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention. Example

[0022] Currently, the mud generated during bored pile construction is pumped to the screening layer via an external pump. The filtered mud falls into the mixing chamber, where lime powder is added through the upper feed inlet. After thorough mixing, it is pumped into the solidification mechanism. The mud adheres to the surface of the filter plate and is then pressed by jacks to solidify into mud blocks that fall off. However, existing mud solidification equipment has the following drawbacks during use: lime powder is usually sprinkled into the mixing chamber manually. Manual sprinkling is slow and cannot be done intermittently, which affects the uniformity of mixing.

[0023] For this purpose, please refer to Figure 1-5 This utility model provides a mud solidification treatment device, including: a mud mixing chamber 1, a filter screen 17 fixedly connected to the inner wall of the mud mixing chamber 1, a conveying pipe 13 connected to the inside of the mud mixing chamber 1 at the position of the left side wall near the front side wall, and an external pipe 12 connected to the inside of the mud mixing chamber 1 at the position of the right side wall near the rear side wall, and two symmetrically distributed stirring shafts 14 rotatably connected to the inner top wall of the mud mixing chamber 1, and multiple stirring rods 15 fixedly connected to the outer wall of each of the two stirring shafts 14, the top of one of the stirring shafts 14 extending to the top of the mud mixing chamber 1 and connected to the output shaft of a motor 16, and a feeding channel 11 opened in the middle of the top of the mud mixing chamber 1, and an intermittent feeding structure 2 installed at the feeding channel 11; the intermittent feeding structure 2 is used to intermittently feed lime powder into the mud mixing chamber 1.

[0024] The existing process for mud solidification treatment involves first turning on an external pump, which then transports the mud from the mud tank to a filter screen layer (filter screen 17) via an external pipe 12. After filtering out impurities and larger particles, the mud flows into a mud mixing chamber 1. Lime powder is added at the feed inlet, and the mud is thoroughly mixed in the mixing chamber before being conveyed to a mud filter plate for pressing. Before conveying, a hydraulic jack is used to compact the filter plate, maintaining a stable pressure. Then, the pump is turned on, conveying the thoroughly mixed mud to the filter plate, where it adheres to the surface. After pressing, water flows through the filter holes into a collection tank and is discharged through a drain pipe. The pressure from the jack is then released, and the solidified mud falls off the filter plate under its own weight.

[0025] Further as Figure 1-5As shown, it is worth noting that in order to allow lime powder to be intermittently added to the mud mixing chamber 1, an intermittent feeding structure 2 is provided, including a feeding hopper 22 slidably connected at the feeding channel 11. A baffle plate 21 is fixed to the inner top wall of the mud mixing chamber 1 in the middle of the feeding channel 11. The top of the baffle plate 21 is flush with the bottom outlet of the feeding hopper 22. Sliding blocks 23 with a convex vertical cross-section are fixed to both sides of the feeding hopper 22. The sliding blocks 23 are slidably connected to the grooves opened in the inner wall of the feeding channel 11. Sprockets a24 are fixed to the outer sides of the two mixing shafts 14. The two sprockets a24 are connected to sprockets b26 through a chain 25. The sprockets b26 are rotatably connected to the inner top wall of the mud mixing chamber 1 through a rotating shaft 27. The top of the rotating shaft 27 extends... A turntable 28 is fixed to the top of the mud mixing chamber 1. A push-pull rod 29 is rotatably connected to the edge of the turntable 28. The other end of the push-pull rod 29 is rotatably connected to the outside of the feeding hopper 22. L-shaped guide rods 210 are fixed to both side walls of the feeding hopper 22. C-shaped moving rods 211 are slidably sleeved on the outside of the two L-shaped guide rods 210. A striking ball 214 is fixed to the top of the two C-shaped moving rods 211. A roller 212 is rotatably connected to the bottom of the two C-shaped moving rods 211. Guide seats 213 are fixed to the top of the mud mixing chamber 1 on both sides of the middle of the feeding channel 11. The cross-section of the guide seats 213 is an isosceles trapezoidal structure. The opposite side walls of the two C-shaped moving rods 211 are fixed to the L-shaped guide rods 210 through S-shaped spring pieces 215.

[0026] The guide seat 213 is designed so that the roller 212 can be squeezed by the inclined surfaces on both sides of the guide seat 213 during the back and forth movement, so that the two C-shaped moving rods 211 move away from each other and, under the action of the rebound force of the S-shaped spring sheet 215, they can strike the outer wall of the feeding hopper 22.

[0027] In summary: After the required lime powder is added to the feeding hopper 22, the slurry filtered by the filter screen 17 is stirred by starting the motor 16. With the combined action of sprocket a24, chain 25, and sprocket b26, the stirring action causes the turntable 28 connected to the shaft 27 to rotate. Furthermore, the push-pull rod 29 causes the feeding hopper 22 to move back and forth. When the bottom of the feeding hopper 22 is in contact with the top of the baffle plate 21, the lime powder in the feeding hopper 22 is intercepted and prevented from discharging. When the bottom of the hopper 22 moves to the front and rear sides of the baffle plate 21, the lime powder will fall into the mud mixing chamber 1, thereby realizing the intermittent feeding of lime powder and effectively ensuring the uniformity of mixing between mud and lime powder. Secondly, during the reciprocating back and forth movement of the feeding hopper 22, due to the shape design of the guide seat 213 and the setting of the roller 212, the two C-shaped moving rods 211 will move in opposite directions, and the rebound force of the S-shaped spring sheet 215 after being squeezed and deformed will be used to knock on the outer wall of the feeding hopper 22.
