Abstract
Description

Common mud-water separation devices include: centrifugal, filter belt, spiral ring disc and plate and frame types. Among them, the spiral ring disc type is widely used in industry due to its high adaptability and high separation rate.
[0003] Currently, the spiral ring disc type mud-water separator on the market consists of fixed rings and moving rings stacked on top of each other, and a spiral shaft passes through them to form a filtration main body.

The filtrate is discharged from the filter slits formed by the fixed ring and the movable ring, and the mud cake is discharged from the end of the dehydration part. However, in order to ensure the discharge efficiency of the filtrate, the filter slits are usually set to a certain size, so that there is still a certain amount of residue in the filtrate passing through the spiral ring disc and it cannot be directly discharged.

[0027] Please refer to Figures 1-6, the present utility model provides the following technical solutions:
[0028] A mud-water separation device, including a frame body 1, on which a spiral ring separation mechanism 2 and a filter belt separation mechanism 5 are installed. A water blocking mechanism 3 and a first mud discharging plate 4 are arranged at the slag discharging port 26 of the spiral ring separation mechanism 2. When the mud slag separated by the spiral ring separation mechanism 2 moves to the slag discharging port 26, it pushes open the water blocking mechanism 3 and is discharged by the first mud discharging plate 4. When the water content in the mud slag at the slag discharging port 26 is relatively high at the beginning of startup, the thrust of the mud slag on the water blocking mechanism 3 is relatively small and cannot open the water blocking mechanism 3, thus avoiding the discharge of mud slag with a relatively high water content. When continuously operating, the amount of mud slag at the slag discharging port 26 increases and the water content decreases, and the thrust on the water blocking mechanism 3 increases, so that the water blocking mechanism 3 can be pushed open to discharge the mud slag, improving the effect of mud-water separation;
[0029] The filter belt separation mechanism 5 is arranged below the spiral ring separation mechanism 2. One end of the filter belt separation mechanism 5 facing the slag discharging port 26 is provided with a second mud discharging plate 6. The filtrate initially separated by the spiral ring separation mechanism 2 is filtered again on the filter belt separation mechanism 5, and the separated mud slag is discharged by the second mud discharging plate 6. A scraper 61 is arranged on the second mud discharging plate 6. The scraper 61 is arranged on the side of the filter belt 55 and is in contact with the filter belt 55. The scraper 61 scrapes the surface of the filter belt 55, thereby reducing the mud slag adhered to the filter belt 55 and ensuring the discharge of the mud slag;
[0030] A cleaning mechanism 7 and a tensioning mechanism 8 are arranged on the filter belt 55 of the filter belt separation mechanism 5. The filter belt that has carried mud water is cleaned by the cleaning mechanism 7. After removing the residual mud slag on the surface of the filter belt 55, it repeats filtering the filtrate, ensuring the through-flow efficiency of the filter belt 55 and the mud-water separation efficiency; The tensioning mechanism 8 can adjust the tension of the filter belt 55 according to the amount of filtrate falling on the filter belt 55, thereby ensuring the normal movement of the filter belt 55.
[0031] The filter belt separation mechanism 5 includes a power source 51. A driving roller 52 is connected to the output shaft of the power source 51. The driving roller 52 drives the filter belt 55 to move through friction. A plurality of tensioning rollers 53 and adjusting rollers 54 are installed on the frame body 1. The filter belt 55 is jointly tensioned by the driving roller 52, a plurality of tensioning rollers 53 and the adjusting roller 54. The tensioning mechanism 8 includes a hydraulic rod 81. The output end of the hydraulic rod 81 is connected to both ends of the adjusting roller 54. A chute 82 is correspondingly opened on the frame body 1. The hydraulic rod 81 pushes the adjusting roller 54 to slide in the chute 82, thereby adjusting the tension of the filter belt 55;
[0032] The filter belt 55 is joined end to end. The upper side of the filter belt 55 is the upper filter belt, and the lower side is the lower filter belt. A first liquid collection tank 56 and a second liquid collection tank 57 are installed on the frame 1. The first liquid collection tank 56 is arranged below the upper filter belt to collect the filtrate after secondary filtration through the filter belt 55. The second liquid collection tank 57 is arranged below the lower filter belt. A cleaning mechanism 7 is arranged on the lower filter belt. The cleaning mechanism 7 is correspondingly arranged above the second liquid collection tank 57. The sewage generated when the cleaning mechanism 7 flushes the filter belt 55 is collected through the second liquid collection tank 57.
[0033] The cleaning mechanism 7 includes a fixed frame 71. One side of the fixed frame 71 is provided with an opening, and the opening of the fixed frame 71 faces the filter belt 55. A water pipe 72 is installed inside the fixed frame 71. A number of spray heads 73 are installed on the water pipe 72, and the spray heads 73 spray water onto the filter belt 55. A brush 74 is installed on the frame 1. The brush 74 is arranged below the filter belt 55. The brush 74 cooperates with the sprayed water above to brush the filter belt 55, ensuring the cleaning effect, and at the same time reducing the splashing range of the sprayed water passing through the filter belt 55, ensuring the collection efficiency of the second liquid collection tank 57.
[0034] The spiral ring separation mechanism 2 includes a driving component 22. The output end of the driving component 22 is connected to a filtering main body 23. An annular filter screen 24 is arranged around the filtering main body 23. The annular filter screen 34 can conduct primary filtration on the passing muddy water, and at the same time limit the range of mud residues, facilitating the extrusion of mud residues by the filtering main body 23;
[0035] A shell cover 25 is arranged outside the annular filter screen 24. The lower wall of the shell cover 25 is a filter screen. A slag discharge port 26 is arranged at one end of the shell cover 25. The other end of the shell cover 25 is communicated with a feed pipe 22. The bottom of the shell cover 25 is a filter cloth, which is above the filter belt 55 and the first liquid collection tank 56, which can enhance the filtering effect, and at the same time buffer the filtrate passing through the annular filter screen 24, reducing the impact force when it falls on the filter belt 55 and avoiding the splashing of the filtrate.
[0036] The water blocking mechanism 3 includes a fixing plate 31. The fixing plate 31 is fixed on the frame 1. One end of the filtering main body 23 is rotatably installed on the fixing plate 31. A number of springs 33 are arranged on the fixing plate 31. The other ends of the number of springs 33 are jointly connected to a sealing plate 32. The sealing plate 32 is slidably connected to the rotating shaft of the filtering main body 23, and the sealing plate 32 can cover the slag discharge port 26; When starting up, the mud residues pushed to the slag discharge port 26 by the filtering main body 23 have a high water content, so they are prone to deformation and have a small thrust on the sealing plate 32, and it is not easy to open the sealing plate 32, thus avoiding the discharge of mud residues with a high water content. Continuing to operate for a certain period of time, almost all the water in the mud residues at the slag discharge port is squeezed out. When the solid mud residues are pushed by the filtering main body 23, they have a large thrust and can easily push open the sealing plate 32, and thus are discharged through the slag discharge port 26. That is, through the water blocking mechanism 3, it is ensured that the mud residues passing through the slag discharge port 26 have a low water content, ensuring the muddy water separation efficiency.
[0037] Specifically, a water blocking mechanism 3 is provided at the slag discharge port 26 of the spiral ring disc separation mechanism 2. Under normal conditions, the sealing plate 32 fits on the slag discharge port 26 under the action of the spring 33. When the machine is just started, the amount of compressed sludge in the filter main body 23 is small and contains more water. When the sludge moves to the water blocking mechanism 3, a certain extrusion force is required to push open the sealing plate 32, that is, more sludge needs to be pushed to the slag discharge port, thereby reducing the water content at the slag discharge port and improving the efficiency of mud-water separation.
[0038] The lower wall of the housing 25 of the spiral ring disc separation mechanism 2 is set in a filter mesh shape, and the filtrate falls on the filter belt 55 of the lower filter belt separation mechanism 5 below, for secondary filtration. The filtrate is discharged from the liquid collection tank 56 through the filter belt 55. The sludge is driven by the filter belt 55 and finally scraped off by the scraper 61. After the filter belt 55 is cleaned by the cleaning mechanism 7, the above process is repeated, ensuring the flow efficiency of the filter belt 55 and the efficiency of mud-water separation.
