Description

Technical Field

[0001] This utility model belongs to the field of cement manufacturing technology, specifically relating to a sewage-water separation mechanism. Background Technology

[0002] Sludge-water separation in the cement manufacturing industry helps reduce wastewater discharge, protect the environment, lower costs, and improve production efficiency. This is because the separated water can be reused, reducing the need for fresh water and thus lowering production costs.

[0003] The process of separating sludge into mud and water involves introducing cement slurry into a thickening tank, adding chemicals for flocculation, and performing preliminary mud-water separation. The clean water flows into a clear water tank and can be recycled after meeting environmental standards. The mud at the bottom of the tank flows by gravity to the mud-water separator, moves with the filter cloth, and is continuously squeezed out of the mud by a belt filter press, finally forming a solid mud cake with low water content that is discharged. The cloth plate is an important component of the belt filter press. Its function is to evenly distribute the material to be dewatered on the filter cloth to facilitate effective solid-liquid separation in the subsequent filtration process.

[0004] like Figure 1 As shown, the traditional design of the material distribution plate is usually vertical, with its direction along the transmission direction of the filter cloth and perpendicular to the filter cloth. Because the material distribution plate is vertical, the material distribution on it may be uneven, resulting in uneven material thickness on the filter cloth, which in turn affects the solid-liquid separation effect. When distributing material onto the filter cloth, the vertical material distribution plate may generate significant friction, leading to accelerated wear and shortened service life. Furthermore, the vertical material distribution plate needs to overcome considerable friction when pushing material, which increases energy consumption and reduces equipment operating efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model proposes a sewage-water separation mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sewage-water separation mechanism includes a belt filter press. The frame of the belt filter press is provided with a weir located above the filter cloth, a cloth feeding assembly located inside the weir and with an adjustable angle for feeding the material to be dewatered, and a height limiting assembly for conveying the material to be dewatered at a height that is adjustable.

[0008] The angle-adjustable fabric assembly includes a fabric plate and a connecting rod A fixedly disposed above the fabric plate;

[0009] The height-adjustable height limiting component includes a height limiting plate and a connecting rod B fixedly installed above the height limiting plate.

[0010] Preferably, the cofferdam includes an inverted U-shaped support A, a U-shaped enclosure plate fixed to the front side of the bottom of the inverted U-shaped support A, and baffles that are threadedly connected to the three sides of the U-shaped enclosure plate and inclined inward.

[0011] The inverted U-shaped support A and the U-shaped surrounding plate can form a stable cofferdam structure, effectively preventing the outflow of cement slurry.

[0012] Preferably, the inverted U-shaped bracket A is connected to the top of the frame by bolts and threads, and the baffle is located above the filter cloth.

[0013] Preferably, the connecting rod A on the fabric plate passes through the through hole in the inverted U-shaped bracket B and is locked and positioned by two locking nuts A at the upper and lower ends of the inverted U-shaped bracket B.

[0014] Connecting rod A can rotate within the through hole on the inverted U-shaped bracket B, allowing for easy adjustment of the fabric plate angle by rotating connecting rod A, and then locking and positioning it by two locking nuts A.

[0015] Preferably, the connecting rod B on the height limit plate passes through the through hole in the inverted U-shaped bracket C and is locked and positioned by two locking nuts B at the upper and lower ends of the inverted U-shaped bracket C.

[0016] The connecting rod B can move up and down within the through hole on the inverted U-shaped bracket C to easily adjust the height of the height limit plate, and then be locked in place by two locking nuts B.

[0017] Preferably, the inverted U-shaped bracket B and the inverted U-shaped bracket C are respectively connected to the top of the frame by bolts and threads.

[0018] Preferably, the U-shaped enclosure is also connected to the inverted U-shaped bracket B and the inverted U-shaped bracket C via corner plates.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are:

[0020] The weir in this sewage-water separation mechanism effectively blocks the outflow of filtrate, allowing solid-liquid separation of materials within a certain area, thus improving the utilization rate of the filter cloth and the dewatering efficiency. The cloth assembly, through the angle-adjustable cloth plate and connecting rod A, facilitates the distribution of the material to be dewatered, forming a uniform layer thickness on the filter cloth, thereby improving the solid-liquid separation effect. The height limiting assembly, through the connecting rod B and the height limiting plate, limits the height of the material to be dewatered, preventing the material from overflowing during the filtration process, improving the dewatering efficiency, and reducing the wear and damage of the equipment.

[0021] By setting up cofferdams, material distribution components, and height limiting components, the material to be dewatered can be distributed more evenly, optimizing the distribution of material on the filter cloth and improving the solid-liquid separation effect. By effectively controlling the height and distribution of the material, the friction force that needs to be overcome when pushing the material is reduced, energy consumption is reduced, the energy efficiency ratio of the equipment is improved, the material distribution and control are optimized, the frequency of filter cloth replacement and maintenance is reduced, production downtime is reduced, and production efficiency is improved. By improving the separation effect and reducing energy consumption, production costs can be reduced, including but not limited to material costs, labor costs, and equipment maintenance costs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a sewage-water separation mechanism, including a belt filter press 1. The frame 2 of the belt filter press 1 is provided with a weir 4 located above the filter cloth 3, a cloth feeding assembly 5 located inside the weir 4 and whose angle for feeding the material to be dewatered is adjustable, and a height limiting assembly 6 for conveying the material to be dewatered at a height limit.

[0030] The angle-adjustable fabric assembly 5 includes a fabric plate 501 and a connecting rod A502 fixedly disposed above the fabric plate 501.

[0031] The height-adjustable height limiting component 6 includes a height limiting plate 601 and a connecting rod B602 fixedly disposed above the height limiting plate 601.

[0032] The main purpose of setting up a weir 4 on the material level of the frame 2 of the belt filter press 1 is to prevent the material from overflowing during the filter pressing process and to ensure the smooth progress of the filter pressing process. Without the weir 4, the material may overflow due to the reduction in volume during the solid-liquid separation process, causing on-site pollution and equipment damage. The weir 4 can limit the diffusion range of the material on the filter cloth 3, so that the material can be separated into solid and liquid in a certain area, thereby improving the utilization rate and dewatering efficiency of the filter cloth 3.

[0033] During the operation of the belt filter press 1, the material is evenly distributed on the filter cloth 3 under the action of the cloth plate 501. The adjustable cloth assembly 5 facilitates the distribution of the material to be dewatered, making the distribution of the material on the filter cloth 3 more uniform, which is conducive to improving the solid-liquid separation effect and accelerating the separation speed. The adjustable cloth assembly 5 can reduce friction on the filter cloth 3, reduce wear, extend the service life of the filter cloth 3, reduce the frequency of filter cloth 3 replacement, and reduce maintenance costs.

[0034] During the operation of the belt filter press 1, as the material passes through the pressing zone on the filter cloth 3, its height may continuously increase as water is further removed. If this is not controlled, it may cause material overflow, resulting in on-site pollution and equipment damage. Therefore, to prevent material overflow during conveying and ensure the smooth operation of the filtration process, a height-adjustable height-limiting component 6 is used to limit the height of the material to be dewatered, ensuring the smooth progress of the filtration process. Simultaneously, height-limited conveying can also improve the dewatering efficiency of the filter press, reduce equipment wear and damage, and extend the service life of the equipment.

[0035] The cofferdam 4 includes an inverted U-shaped support A401, a U-shaped enclosure 402 fixedly installed on the front side of the bottom of the inverted U-shaped support A401, and baffles 403 that are connected to the three sides of the U-shaped enclosure 402 by screws and inclined inward.

[0036] The inverted U-shaped support A401 and the U-shaped enclosure 402 can form a stable dam 4 structure, effectively blocking the outflow of cement slurry and improving the separation effect of sludge and water. The baffle 403 can limit the material to be dewatered, so that it is distributed on the filter cloth 3 surrounded by the U-shaped enclosure 402 and the baffle 403.

[0037] The inverted U-shaped bracket A401 is connected to the top of the frame 2 by bolts and threads, and the baffle 403 is located above the filter cloth 3.

[0038] The connecting rod A502 on the fabric plate 501 passes through the through hole in the inverted U-shaped bracket B504 and is then locked and positioned by the two locking nuts A503 at the upper and lower ends of the inverted U-shaped bracket B504.

[0039] The connecting rod A502 can rotate within the through hole on the inverted U-shaped bracket B504, facilitating angle adjustment of the material plate 501. It is then locked in place by two locking nuts A503 to achieve the optimal contact angle between the material plate 501 and the filter cloth 3, thereby improving the uniform distribution of material on the filter cloth 3. Angle adjustment allows for the formation of a uniform layer thickness on the filter cloth 3, contributing to improved solid-liquid separation efficiency, faster separation speed, and enhanced overall separation effect. Locking in place with the locking nuts A503 allows for quick installation and removal of the material plate 501, facilitating equipment maintenance and saving time and labor costs.

[0040] The connecting rod B602 on the height restriction plate 601 passes through the through hole in the inverted U-shaped bracket C604 and is locked and positioned by the two locking nuts B603 at the upper and lower ends of the inverted U-shaped bracket C604.

[0041] The connecting rod B602 can move up and down within the through hole on the inverted U-shaped bracket C604, facilitating the adjustment of the height limit plate 601 to achieve accurate height limitation of the material to be dewatered. This ensures the stability and uniformity of the material during the filtration process. By precisely controlling the material height, the distribution of the material on the filter cloth 3 can be optimized, thereby improving the solid-liquid separation effect. The height limit plate 601 can be quickly installed and removed by locking it with two locking nuts B603, facilitating equipment maintenance and saving time and labor costs.

[0042] The inverted U-shaped brackets B504 and C604 are respectively connected to the top of the frame 2 by bolts and threads.

[0043] The U-shaped enclosure 402 is also connected to the inverted U-shaped bracket B504 and the inverted U-shaped bracket C604 via the corner plate 7.

[0044] The installation of the corner plate 7 makes the connection between the U-shaped cofferdam 402 and the inverted U-shaped brackets B504 and C604 more secure, enhancing the stability of the entire cofferdam 4 structure and ensuring that there will be no displacement or deformation during operation.

[0045] This sludge-water separation mechanism, through the configuration of a belt filter press 1, a weir 4, a cloth assembly, and a height limiting assembly, can effectively separate sludge into solid and liquid, improving separation efficiency, reducing energy consumption, extending the service life of the filter cloth 3, lowering production costs, increasing production efficiency, and meeting environmental protection requirements. Furthermore, the adjustable-angle cloth assembly 5 and the adjustable-height height limiting assembly 6 allow for more even distribution of the material to be dewatered, enhancing the solid-liquid separation effect.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
