Description
Technical Field
[0001] This utility model belongs to the field of concrete production separation technology, specifically a high-strength concrete production separation device. Background Technology
[0002] Concrete is a slurry that can be cured and shaped by mixing cement, sand, water, and, if necessary, admixtures and additives in a certain proportion. It is widely used in the construction industry.
[0003] During the production of high-strength concrete, various materials need to be added to the mixing unit according to the specified ratio, and a certain amount of water is added for mixing. After the concrete is discharged from the mixing unit, the residual concrete slurry needs to be rinsed to prevent the residual high-strength concrete slurry from solidifying in the mixing unit. The rinsing water will contain some concrete sand, and direct discharge of this water can easily cause blockage of the drainage pipes. Therefore, solid-liquid separation is required. When performing solid-liquid separation on wastewater containing concrete sand, most of the sand is usually filtered first using a filtration unit, and then the wastewater is allowed to settle, allowing the remaining sand particles to settle to the bottom. After settling, the water above is gradually discharged. However, at this time, the sand at the bottom of the sedimentation tank still contains a lot of water, and the separation is not thorough enough, making it inconvenient for subsequent treatment and transfer.

Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 5As shown, a high-strength concrete production and separation device according to an embodiment of this utility model includes a frame 1; two pairs of take-up rollers 12 are installed on the top of the frame 1; a cable 13 is installed in the middle of each pair of take-up rollers 12; the two ends of the cable 13 are respectively fixed to the middle of a pair of take-up rollers 12; multiple connecting mechanisms are installed in the middle of a pair of cables 13; filter cloth 14 is installed in the middle of the multiple connecting mechanisms; a guide platform 15 is fixed to the bottom of the frame 1; a top block 16 is fixed to the top of the guide platform 15; a drive assembly is installed on the top of the frame 1; the multiple take-up rollers 12 rotate through the operation of the drive assembly; during operation, concrete sand containing a certain amount of moisture, extracted after sedimentation, is poured into the filter cloth 14, and the moisture in the concrete sand gradually permeates through the filter cloth 14 and drips downwards. The concrete is placed on the guide platform 15 and then discharged down along the guide platform 15. After a period of time, the water and liquid in the concrete sand are fully separated. At this time, the operation of the drive component causes multiple take-up rollers 12 to rotate simultaneously to unwind the cable 13, causing the filter cloth 14 to descend. The middle of the filter cloth 14 will fall onto the top block 16, and then the edge of the filter cloth 14 will continue to descend. Finally, after the edge of the filter cloth 14 descends to a certain extent, the concrete sand that was originally caught by the filter cloth 14 will slide off the filter cloth 14 onto the guide platform 15. Then, the collection device collects these concrete sand. Through the above structure, the concrete sand can be further separated into solid and liquid, and the water content of the concrete sand after treatment can be further reduced, so as to facilitate the transfer of the concrete sand and other subsequent treatments.
[0025] like Figures 1 to 4 As shown, the drive assembly includes a motor 2; the motor 2 is fixedly connected to the top of the frame 1; a worm gear 21 is fixedly connected to the output end of the motor 2; a first transmission rod 22 is rotatably connected to the top of the frame 1; a worm wheel 23 is fixedly connected to the middle of the first transmission rod 22; a pair of second transmission rods 24 are rotatably connected to the top of the frame 1; both ends of the second transmission rods 24 are connected to the end of a take-up roller 12 and rotate synchronously with the take-up roller 12; the first transmission rod 22 and the second transmission rods 24 are driven by bevel gears; during operation, when it is necessary to take up the cable 13... When the filter cloth 14 is rolled up or unrolled, causing the edge to rise or fall, the motor 2 is started to drive the worm gear 21 to rotate. Then, through the cooperation of the worm gear 21 and the worm wheel 23, the first transmission rod 22 is driven to rotate. Then, through the transmission of the bevel gear, a pair of second transmission rods 24 are driven to rotate, so that multiple take-up rollers 12 rotate simultaneously and at the same speed. With the above structure, multiple take-up rollers 12 can be driven to rotate simultaneously and at the same speed by a single drive source, so that the filter cloth 14 will not easily become uneven after being raised or lowered.
[0026] like Figures 1 to 5As shown, a drainage trough 3 is provided in the middle of the guide platform 15; multiple drainage pipes 31 are fixedly connected to the bottom of the drainage trough 3; the other end of the drainage pipe 31 is opened on the side wall of the frame 1; a cover plate 32 is slidably connected to the middle of the guide platform 15; a limit rod 33 is slidably connected to the side wall of the frame 1; during operation, when filtering water from the concrete sand on the filter cloth 14, the water will fall onto the guide platform 15 and flow into the drainage trough 3, and then be discharged automatically through the multiple drainage pipes 31. The outlet of the drainage pipe 31 is connected to a floor drain or... The device is connected to the collection device, which can directly discharge or collect the filtered water. After the water is fully separated, the limiting rod 33 is pulled up, so that the cover plate 32 slides down the guide platform 15 and covers the drainage tank 3. This makes it difficult for the concrete sand on the filter cloth 14 to fall into the drainage tank 3. Through the above structure, the filtered water can be easily discharged or collected, reducing the situation where the water flows directly down the guide platform 15 and is inconvenient to collect and discharge, thus preventing the pollution of the ground and improving the ease of use of the device.
[0027] like Figures 1 to 3 As shown, the connecting mechanism includes multiple limiting pulleys 4; the multiple limiting pulleys 4 are fixed to the middle of the cable 13; a connecting ring 41 is sleeved on the middle of the limiting pulleys 4; one end of the connecting ring 41 is rotatably and slidably connected to a connecting sleeve 42; the other end of the connecting sleeve 42 is threadedly engaged with the other end of the connecting ring 41; the connecting ring 41 passes through the middle of the filter cloth 14; during operation, after the filter cloth 14 has been used for a long time, it may become damaged. At this time, the connecting sleeve 42 can be rotated to open the connecting ring 41, and then the connecting ring 41 can be separated from the filter cloth 14, so that the filter cloth 14 can be removed for repair or replacement. After replacement, the connecting ring 41 and the filter cloth 14 can be reconnected. When connecting the filter cloth 14 to the cable 13 via multiple connecting rings 41, the multiple connecting rings 41 are restricted to different positions in the middle of the cable 13 by the limiting pulley 4, making it difficult for the multiple connecting rings 41 to gather together on the cable 13. This allows the filter cloth 14 to be unfolded as much as possible, facilitating the reception of concrete sand when it is placed on the filter cloth 14. With the above structure, the filter cloth 14 can be easily disassembled for replacement or maintenance. After the filter cloth 14 is installed, it can be unfolded as much as possible to receive concrete sand, improving the ease of use of the device.
[0028] like Figures 1 to 3As shown, multiple collars 5 are fixed to the middle of the filter cloth 14; a connecting ring 41 is set through the middle of the collars 5; during operation, if there were no collars 5, the middle of the filter cloth 14 would be in direct contact with the middle of the connecting ring 41. After the filter cloth 14 bears concrete sand, the filter cloth 14 may be torn at the contact point with the connecting ring 41. By setting the collars 5, the collars 5 can bear the tensile force, thereby reducing the occurrence of the filter cloth 14 being torn and improving the service life of the filter cloth 14.
[0029] like Figures 1 to 4 As shown, both ends of the second transmission rod 24 are fixedly connected to connecting rods 6; the end of the take-up roller 12 is slidably fitted with the connecting rod 6; the take-up roller 12 is threadedly connected to the top of the frame 1; during operation, as the take-up roller 12 rotates with the second transmission rod 24, the first transmission rod 22 rotates and moves under the action of the thread. At this time, the second transmission rod 24 slides relative to the take-up roller 12. The take-up roller 12, which moves and rotates at the same time, will evenly wind the cable 13 in the middle, so that each turn of the cable 13 wound in the middle of the take-up roller 12 is difficult to contact and rub against each other. Through the above structure, the cable 13 wound on the take-up roller 12 can be evenly distributed, and the wear caused by the mutual friction of the middle of the cable 13 can be reduced, thereby improving the service life of the cable 13.
[0030] like Figure 1 As shown, the filter cloth 14 is made of high-strength material; the cable 13 is also made of high-strength material. Through the above structure, the occurrence of cable 13 breaking under stress or filter cloth 14 being damaged under stress can be reduced, so that the device can perform solid-liquid separation treatment on more concrete sand at one time.
[0031] During operation, concrete sand containing a certain amount of moisture, extracted after sedimentation, is poured into filter cloth 14. The moisture in the concrete sand gradually permeates through filter cloth 14 and drips down onto guide platform 15, then flows down along guide platform 15. After a period of time, the water and liquid in the concrete sand are fully separated. At this point, the operation of the drive assembly causes multiple take-up rollers 12 to rotate simultaneously, unwinding the cable 13, causing filter cloth 14 to descend. The middle of filter cloth 14 falls onto top block 16, and then the edges of filter cloth 14 continue to descend. Finally, after the edges of filter cloth 14 have descended to a certain extent, the concrete sand originally caught by filter cloth 14 will slide off filter cloth 14 onto guide platform 15. The concrete sand is collected by a collection device. When the cable 13 needs to be wound up or unwound to raise or lower the edge of the filter cloth 14, the motor 2 is started to drive the worm gear 21 to rotate. Then, through the cooperation of the worm gear 21 and the worm wheel 23, the first transmission rod 22 is driven to rotate. Then, through the transmission of the bevel gear, a pair of second transmission rods 24 are driven to rotate, so that multiple winding rollers 12 rotate simultaneously at the same speed. When filtering water from the concrete sand on the filter cloth 14, the water will fall onto the guide table 15 and flow into the drainage trough 3. Then, it will be discharged automatically through multiple drainage pipes 31. The outlet of the drainage pipes 31 is connected to a floor drain or a collection device through a pipe. The filtered water can be directly discharged or collected. After the water is fully separated, the limiting rod 33 is pulled up, causing the cover plate 32 to slide down along the guide platform 15 and cover the drainage trough 3. This prevents concrete sand from falling into the drainage trough 3. After prolonged use, the filter cloth 14 may become damaged. In this case, the connecting sleeve 42 can be rotated to open the connecting ring 41, and then the connecting ring 41 can be separated from the filter cloth 14. The filter cloth 14 can then be removed for repair or replacement. After replacement, the connecting ring 41 can be reconnected to the filter cloth 14. When connecting the filter cloth 14 to the cable 13 through multiple connecting rings 41, due to the multiple connections... As the limiting pulley 4 restricts the ring 41 to different positions in the middle of the cable 13, multiple connecting rings 41 are difficult to gather together on the cable 13, so that the filter cloth 14 can be spread out as much as possible, which is convenient for receiving the concrete sand when it is put into the filter cloth 14. When the winding roller 12 rotates with the second transmission rod 24, the first transmission rod 22 will rotate and move under the action of the thread. At this time, the second transmission rod 24 will slide relative to the winding roller 12. The winding roller 12, which moves and rotates at the same time, will evenly wind the cable 13 in the middle, so that each turn of the cable 13 wound in the middle of the winding roller 12 is difficult to contact and rub against each other.
