Description

Technical Field

[0001] The invention relates to the technical field of separation devices, and in particular to a tunnel construction waste cement water separation device. Background Art

[0002] During tunnel construction, different geological units will be passed through. As the excavation depth increases, groundwater may seep out or form gushing water, and mix with mud, rock cuttings, etc. generated during the tunnel construction to form wastewater. In order to facilitate management, a separation device is required to separate the mud and water. Since there is a lot of wastewater during tunnel construction, sedimentation separation is used for separation.

[0003] However, although the existing sedimentation separation can separate the mud and water and ensure that no mud remains in the water when it is taken out, some liquid moisture will still remain in the mud when it is discharged, so that the existing separation device requires additional equipment to separate the mud containing moisture again after completing the separation, which makes the separation process during construction more cumbersome. For this reason, the present application designs a tunnel construction waste cement water separation device, which can completely separate the mud and moisture, avoid the waste of liquid caused by residual moisture in the mud, and complete the separation operation when discharging the mud without the need for additional equipment for secondary separation.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. During sedimentation, the mud in the wastewater will settle downward, so that the water above will be separated from the mud. In order to concentrate the mud, the driving motor can drive the rotating seat to rotate. When the rotating seat rotates, the first extension frame and the second extension frame above will rotate, so that the first scraper and the second scraper can scrape the bottom of the accumulation tank and the sedimentation tank respectively, so that the mud will be concentrated at the mud discharge port of the accumulation tank;

[0023] By setting up an inclined pipe rack so that each inclined through pipe is inclined, the upward movement of mud will be blocked by it, and then the upper mud will settle down again after accumulation. This can ensure that the application will not pollute the upper clean water again when the mud is accumulated. When taking out the clean water, the clean water on the upper side can be pumped out by connecting the drainage pipe through external pumping equipment.

[0024] 2. The output end of the driving motor is started to drive the first auger and the second bevel gear to rotate, and the conveying channel is connected with the mud discharge port of the accumulation tank, so that the mud will enter the conveying channel. The first auger is rotated to transfer the mud to the expansion channel, and then the mud is transferred to the discharge pipe. The fourth bevel gear and the third bevel gear are meshed and driven to rotate the second auger and drive the mud in the discharge pipe to be discharged into the reinforcement component;

[0025] During the soil discharge process, the second bevel gear is driven to rotate by the driving motor, so that the first bevel gear and the second bevel gear are meshed and driven to rotate the rotating seat, thereby realizing the collection and processing of the soil by the separation component to prevent the soil from falling too slowly and causing a large amount of liquid to enter.

[0026] 3. By starting the hydraulic rod, one side of the combined pressure plate can be pushed to move, and the combined pressure plates will be pushed together under the action of several connecting rods, so that each sealed combined tube is combined, and then the soil enters the sealed combined tube through the discharge pipe, and the opening is opened at the bottom of each sealed combined tube so that the soil is evenly distributed between every two combined pressure plates, and then the hydraulic rod is further pushed to reduce the distance between every two combined pressure plates to squeeze the soil and discharge the liquid inside the soil. After completion, the hydraulic rod is reset, and several connecting rods and slide rails can be used to separate and reset each combined pressure plate to discharge the separated soil, so that the present application can timely strengthen the separation treatment of the soil before discharge, avoid the situation where there is a large amount of liquid in the soil after discharge, which requires additional treatment, and also enhance the utilization rate of water resources and reduce water waste.

[0027] 4. During the enhanced separation process, the liquid in the soil will fall and pass through the inclined screen into the inner groove of the extended receiving seat. Then, the diversion slope can be used to discharge the falling liquid to both sides, so that the liquid will be discharged from the drainage pipe. The drainage position is on both sides, so as not to affect the falling of the soil, so that the soil will fall accurately into the mud discharge trough when it falls;

[0028] In order to optimize the separation process, the separated liquid will be returned to the sedimentation tank for unified discharge from the drain pipe. By starting the water delivery pump, the liquid inside the water storage tank will be transferred to the delivery pipe and discharged back to the sedimentation tank. When pumping water, you only need to connect the drain pipe.

[0029] 5. A branch pipe is installed through the delivery pipe body. The solenoid valve is started to transfer part of the liquid into the branch pipe and store it in each liquid-passing pipe. Then, the liquid is put into the expansion bag using the channel opened at the bottom of each liquid-passing pipe. Further pressure is applied during separation to increase the separation strength. After completion, the reflux pump is started to flow the liquid in the liquid-passing pipe and the expansion bag back to the delivery pipe, and the solenoid valve is closed after the reflux is completed until the next round of enhanced separation.

[0055] During sedimentation, the mud in the wastewater will settle downward, so that the water above will be separated from the mud. In order to facilitate the concentration of the mud, the rotating seat 206 can be driven to rotate by the driving motor 7. When the rotating seat 206 rotates, the first extension frame 2071 and the second extension frame 208 above are rotated, so that the first scraper 2073 and the second scraper 2081 can scrape the bottom of the accumulation tank 205 and the sedimentation tank 104 respectively, so that the mud will be concentrated at the mud discharge port of the accumulation tank 205;

[0061] In order to transfer the bottom soil into the reinforcing assembly 5 for high-strength separation, the output end of the driving motor 7 is started to drive the first auger 602 and the second bevel gear 6021 to rotate, and the conveying channel 601 is connected with the mud discharge port of the accumulation tank 205, so that the soil enters the conveying channel 601, and the first auger 602 is rotated to transfer the soil into the expansion channel 6051, and then the soil is transferred to the discharge pipe 605, wherein the fourth bevel gear 607 and the third bevel gear 6022 are meshed and driven to make the second auger 606 rotate and drive the soil in the discharge pipe 605 to be discharged into the reinforcing assembly 5;

[0062] During the soil discharge process, the second bevel gear 6021 is driven to rotate by the driving motor 7, so that the first bevel gear 2061 and the second bevel gear 6021 are meshed and driven to rotate the rotating seat 206, thereby realizing the collection and processing of the soil by the separation component 2 to avoid the situation where the soil falls too slowly and a large amount of liquid enters.

[0063] In the present application, the reinforcing assembly 5 includes a plurality of combined pressing plates 505, slide seats 5056 are arranged on both sides of the combined pressing plates 505, and the inner wall of the fixed bracket 3 is provided with a slide rail 4 for matching the slide seats 5056, and a sealed combined tube 5051 capable of combined connection is installed on the upper end of each combined pressing plate 505, wherein one of the combined pressing plates 505 is fixedly installed inside the fixed bracket 3, wherein one end of the sealed combined tube 5051 on one side is fixedly connected to the discharge pipe 605, and the inside of the sealed combined tube 5051 on the other side is in a blocked state, and an opening is opened at the bottom of each sealed combined tube 5051 and the opening is located between the two combined pressing plates 505;

A turning seat 5054 is installed inside the receiving groove 5053 , and a connecting rod 5055 is rotatably installed between the turning seat 5054 and the adjacent connecting seat 5052 .

[0066] By starting the hydraulic rod 502, the combined pressure plate 505 on one side can be pushed to move, wherein the combined pressure plates 505 will be pushed together under the action of a number of connecting rods 5055, so that each sealed combined tube 5051 is combined, and then the soil enters the sealed combined tube 5051 through the discharge pipe 605, and the opening is opened at the bottom of each sealed combined tube 5051 so that the soil is evenly distributed between every two combined pressure plates 505, and then the hydraulic rod 502 is further pushed to reduce the distance between every two combined pressure plates 505 to squeeze the soil and discharge the liquid inside the soil. After completion, the hydraulic rod 502 is reset, and a number of connecting rods 5055 and the slide rail 4 can be used to separate and reset each combined pressure plate 505 to discharge the separated soil.

[0067] In the present application, a mud discharge groove 503 is installed at the bottom of the fixed bracket 3, a water storage groove 504 is arranged outside the mud discharge groove 503, and guide grooves 510 are opened on both sides of the bottom of the fixed bracket 3;

[0068] An extended receiving seat 50512 is installed at the bottom of each combined pressure plate 505, and a docking slot 50511 is provided at the lower end of each combined pressure plate 505.

[0069] During the enhanced separation process, the liquid in the soil will fall and pass through the inclined screen 50510, entering the internal groove of the extended receiving seat 50512, and then the diversion slope 50514 can be used to discharge the falling liquid to both sides, so that the liquid will be discharged from the drain pipe 50513.

Then, the liquid is loaded into the expansion bag 511 by utilizing the channel opened at the bottom of each liquid-passing pipe 5059.

After completion, the reflux pump 512 is started to make the liquid in the liquid-passing pipe 5059 and the expansion bag 511 flow back to the delivery pipe 507, and the solenoid valve 509 is closed after the reflux is completed until the next round of enhanced separation.

[0074] The working principle of this tunnel construction waste cement water separation device:

[0075] When in use, firstly, wastewater is added into the feed tank 101, then the operator adds coagulant into the feed tank 102, and uses the guide tank 103 to guide the pretreated wastewater into the sedimentation tank 104;

[0076] Then the mud will settle in the sedimentation tank 104, so that the mud goes down and the clear water goes up. In order to avoid excessive accumulation of mud, the output end of the driving motor 7 is started to drive the second bevel gear 6021 to rotate, so that the first bevel gear 2061 and the second bevel gear 6021 are meshed and driven to drive the rotating seat 206 to rotate, so that the first extension frame 2071 and the second extension frame 208 above are rotated, so that the first scraper 2073 and the second scraper 2081 can scrape the bottom of the accumulation tank 205 and the sedimentation tank 104 respectively, so that the mud will be concentrated at the mud discharge port of the accumulation tank 205, and active mud discharge is realized;

[0077] Then, the conveying channel 601 is connected with the mud discharge port of the accumulation tank 205, so that the mud will enter the conveying channel 601, and the mud can be transferred to the expansion channel 6051 by rotating the first auger 602, and then the mud is transferred to the discharge pipe 605, wherein the second auger 606 can be rotated by the meshing transmission of the fourth bevel gear 607 and the third bevel gear 6022 to drive the mud in the discharge pipe 605 to be discharged into the reinforcement component 5, thereby completing the conveying of the mud;

[0078] When there is too much soil, part of the soil will be stored in the reinforcing component 5 through the conveying component 6, which can achieve high-strength separation and avoid the decrease of separation effect caused by excessive soil accumulation;

[0079] The soil enters the sealed combined tube 5051 through the discharge pipe 605, and the opening at the bottom of each sealed combined tube 5051 is used to evenly distribute the soil between each two combined pressure plates 505. Then, the hydraulic rod 502 is further pushed to reduce the distance between each two combined pressure plates 505, thereby squeezing the soil and discharging the liquid inside the soil to achieve separation.

[0080] During the separation process, the liquid in the soil will fall and pass through the inclined screen 50510, and enter the inner groove of the extended receiving seat 50512. Then, the falling liquid can be discharged to both sides by using the guide slope 50514, so that the liquid will be discharged from the drainage pipe 50513. Since the drainage position is on both sides, it will not affect the falling of the soil, so that the soil will fall accurately into the mud discharge groove 503 and be discharged accordingly.
