Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mud treatment equipment, and in particular to a mud centrifugal press dryer. Background Technology
[0002] With the development of the social economy, industries such as ceramics, stone, glass, chemicals, and public utilities have developed rapidly, inevitably generating large amounts of mud and sludge. Therefore, the environmental protection treatment of mud and sludge is particularly important. For example, the stone industry also generates a large amount of mud containing fine sand, soil, and other substances during production. This mud is highly concentrated, viscous, and has small particle size. It usually requires pressing out the water and separating the solid and liquid before further treatment. The traditional treatment method is to use plate and frame filter presses or belt filter presses for solid-liquid separation.
[0003] However, traditional treatment equipment is inefficient, and the separated water contains fine mud and is relatively turbid, resulting in poor separation effect. Utility Model Content
[0004] To overcome at least one of the defects described in the prior art, this utility model provides a mud centrifugal press dryer to solve problems such as poor mud separation.
[0005] The technical solution adopted by this utility model to solve its problem is:
[0006] A mud centrifugal press includes a fixed platform with a trough on the platform. A housing is fixedly installed on the platform within the trough. A drum is rotatably connected inside the housing. Support platforms for supporting the drum are provided at both ends of the drum on the fixed platform. A pusher is rotatably connected inside the drum. The pusher has a conveying port and a receiving chamber at the conveying port. A conveying pipe is connected to the receiving chamber. Centrifugal mechanisms are provided at both ends of the drum. A first drive mechanism and a second drive mechanism are respectively provided at both ends of the drum on the fixed platform.
[0007] The above scheme utilizes the rotation of the drum to create centrifugal force in the slurry, resulting in solid-liquid stratification. A rotating pusher pushes the solids in the slurry to one end for discharge, while the water separated from the slurry is discharged through the other end. This device can separate and collect the solids and water in the slurry during slurry processing, improving slurry separation efficiency and enabling separate treatment of the separated solids and water.
[0008] Furthermore, the housing includes an upper shell and a lower shell, with one side of the upper shell rotatably connected to one side of the lower shell, the lower shell located within the groove, and both ends of the lower shell connected to support platforms on both ends of the fixed platform.
[0009] The above-mentioned further solutions enclose the drum in the upper and lower shells, which reduces the noise it generates and provides protection.
[0010] Furthermore, the pusher is provided with a spiral rib platform, the outer side of which is in contact with the inner side of the drum.
[0011] The above-mentioned further scheme, by rotating the spiral rib platform, can push the solids in the mud to one end, concentrate and squeeze the solids, reduce the water in the mud, and facilitate subsequent mud treatment.
[0012] Furthermore, the diameter of one end of the drum is smaller than the diameter of the other end, and the shape of the pusher is the same as the shape of the drum.
[0013] The above-mentioned further method allows the solid to be pushed to the end with the smaller diameter, and the solid is gradually squeezed to squeeze out the water inside, thereby reducing the water content in the solid and facilitating subsequent processing.
[0014] Furthermore, the centrifugal mechanism is a rotating ring, with two rotating rings fixedly installed on both ends of the drum. The rotating ring is hollow inside and has multiple evenly arranged arc-shaped blades inside. The rotating ring has multiple evenly arranged feed holes on the side facing the drum, and multiple evenly arranged discharge ports on the outer circumference of the rotating ring.
[0015] Through the above-mentioned further scheme, solids or water enter the rotating ring through the feed hole and are then thrown out through the discharge port. When the rotating ring rotates, it can reduce the pressure in the middle, making it easier for solids or water to enter the drum. Its internal arc blades can break up the solids and facilitate their discharge.
[0016] Furthermore, baffles are provided on both sides of the discharge port on the outer circumference of the rotating ring, and the outer circumference of the baffles is in contact with the inner sides of the upper and lower shells.
[0017] Through the above-mentioned further solutions, the baffles can keep the solids or water thrown out of the discharge port between the baffles, preventing them from splashing to other places and thus preventing contamination.
[0018] Furthermore, the bottom of the lower shell is provided with a solid outlet and a liquid outlet below the rotating rings on both sides of the rotating drum.
[0019] Through the above-mentioned further scheme, the solids thrown out of the discharge port are discharged from the solid outlet for treatment, and the water thrown out of the discharge port is discharged from the liquid outlet for treatment.
[0020] Furthermore, the first driving mechanism is a first motor, and the drum is connected to a rotating ring with connecting rings on both ends. The connecting rings are rotatably connected to the support platform, and one end of the connecting ring of the drum extends outward and is connected to the first motor via a belt.
[0021] The above-mentioned further solution involves driving the drum to rotate using a first motor.
[0022] Furthermore, the second drive mechanism is a second motor, and both ends of the pusher are provided with rotating cylinders. The rotating cylinders are rotatably connected in the connecting ring. The rotating cylinder at the end of the pusher away from the first motor extends outward and is connected to the second motor via a belt.
[0023] Through the above-mentioned further scheme, the pusher is driven by a second motor to rotate inside the drum.
[0024] Furthermore, the receiving chamber is in the shape of a horizontal funnel, the tip of the receiving chamber is connected to the conveying pipe, and the conveying port is located at the lowest point of the receiving chamber.
[0025] The above-mentioned further scheme allows the mud conveyed by the conveying pipe to enter the receiving chamber. The conveying port is located at the lowest point of the receiving chamber, so that all the mud in the receiving chamber can enter the drum through the conveying port.
[0026] In summary, the mud centrifugal press dryer provided by this utility model has the following technical effects:
[0027] The rotation of the drum causes centrifugal force to be generated in the mud inside, which in turn causes solid and water to separate. The rotating pusher pushes the solids in the mud to one end for discharge, while the separated water is discharged through the other end. This device can separate and collect the solids and water in the mud during mud treatment, improving the mud separation efficiency and allowing for separate treatment of the separated solids and water.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0036] Example:
[0037] refer to Figure 1 and Figure 2As shown, a mud centrifugal press includes a fixed platform 1, a trough 11 on the fixed platform 1, support platforms 12 at both ends of the trough 11 on the fixed platform 1, a lower shell 22 fixedly installed on the fixed platform 1 inside the trough 11, an upper shell 21 rotatably connected to one side of the lower shell 22, the lower shell 22 is located inside the trough 11, and both ends of the lower shell 22 are fixedly connected to the support platforms 12 at both ends of the fixed platform 1, respectively. A rotating drum 3 is rotatably connected inside the lower shell 22. The upper shell 21 and the lower shell 22 enclose the rotating drum 3, which can reduce the noise generated and provide protection.
[0038] refer to Figure 1 and Figure 2 As shown, a first motor 5 is fixedly installed on one end of the drum 3 on the fixed platform 1. Connecting rings 32 are fixedly connected to both ends of the drum 3 through rotating rings 31. The support platform 12 is provided with support holes 121. The connecting rings 32 are rotatably connected in the support holes 121. A pulley extends outward from one end of the connecting ring 32 of the drum 3 and is connected to the output shaft of the first motor 5 through a belt. The output shaft of the first motor 5 is provided with a pulley connected to the belt, and the drum 3 is driven to rotate by the first motor 5.
[0039] refer to Figure 1 and Figure 2 As shown, two motors are fixedly installed on the fixed platform 1 at the other end of the drum 3. A pusher 4 is rotatably connected inside the drum 3. Both ends of the pusher 4 are provided with rotating cylinders 44. The rotating cylinders 44 are rotatably connected inside the connecting ring 32. The rotating cylinder 44 of the pusher 4 near the second motor 6 extends outward and is provided with a pulley. It is connected to the output end of the second motor 6 by a belt. The output end of the second motor 6 is provided with a pulley connected to the belt. The pusher 4 is driven to rotate inside the drum 3 by the second motor 6.
[0040] It should be noted that the pusher 4 and the drum 3 have a certain speed difference, and the pusher 4 and the drum 3 rotate in the same direction.
[0041] It should be noted that the diameter of one end of the drum 3 is smaller than the diameter of the other end, and the shape of the pusher 4 is the same as that of the drum 3, so that the outer surface of the pusher 4 and the inner surface of the drum 3 have a fixed distance.
[0042] The pusher 4 is equipped with a spiral rib platform 43. The outer side of the spiral rib platform 43 is in contact with the inner side of the drum 3. By rotating the drum 3, the mud inside it generates centrifugal force, which causes solid and water to separate. By rotating the spiral rib platform 43, the solid can be pushed to the end with a smaller diameter, and the solid is squeezed to squeeze out the water inside, reducing the water content in the solid, thereby concentrating the solid for processing and the separated water for processing.
[0043] refer to Figure 2 and Figure 3As shown, the rotating ring 31 is hollow inside, and has multiple evenly arranged arc-shaped blades 311 inside. The rotating ring 31 has multiple evenly arranged feed holes 312 on the side facing the rotating drum 3, and multiple evenly arranged discharge ports 313 on the outer circumference side of the rotating ring 31. Solids and water enter the rotating ring 31 through the feed holes 312 of the rotating ring 31 at both ends of the rotating drum 3, and are then thrown out through the discharge ports 313 on the rotating ring 31. When the rotating ring 31 rotates, it can reduce the pressure in the middle, making it easier for solids or water to enter the rotating drum 3. The arc-shaped blades 311 inside can break up the solids and facilitate their discharge.
[0044] Among them, the arc-shaped blade 311 is arc-shaped, and its end faces the discharge port 313, which can make the solids better thrown out.
[0045] Among them, baffles 314 are provided on both sides of the discharge port 313 on the outer circular side of the rotating ring 31. The outer circular side of the baffle 314 is in contact with the inner side of the upper shell 21 and the lower shell 22. The baffles 314 can keep the solids or water thrown out from the discharge port 313 between the baffles 314, so as not to splash to other places and prevent contamination of other places.
[0046] refer to Figure 2 and Figure 3 As shown, the bottom of the lower shell 22 is provided with a solid outlet 221 and a liquid outlet 222 below the rotating rings 31 on both sides of the rotating drum 3. The solids thrown out by the discharge port 313 are discharged from the solid outlet 221 for processing, and the water thrown out by the discharge port 313 is discharged from the liquid outlet 222 for processing.
[0047] refer to Figure 2 As shown, the pusher 4 is provided with a conveying port 41, and a receiving chamber 42 is provided inside the pusher 4 at the conveying port 41. The receiving chamber 42 is in the shape of a horizontal funnel. The tip of the receiving chamber 42 is connected to the conveying pipe 421. The conveying port 41 is located at the lowest point of the receiving chamber 42, so that the mud conveyed by the conveying pipe 421 enters the receiving chamber 42. The fact that the conveying port 41 is located at the lowest point of the receiving chamber 42 allows all the mud in the receiving chamber 42 to enter the rotating drum 3 through the conveying port 41.
[0048] The working principle of this utility model is as follows:
[0049] The slurry conveyed by the conveying pipe 421 enters the receiving chamber 42. Through the rotation of the pusher 4, a centrifugal force is formed in the receiving chamber 42, causing the slurry in the receiving chamber 42 to enter the space between the drum 3 and the pusher 4. The rotation of the drum 3 causes the slurry inside to undergo centrifugal force, thereby causing solid and water to separate. Through the spiral ribs 43 on the pusher 4, the solid can be pushed to the end with a smaller diameter, and the solid is squeezed to squeeze out the water inside, reducing the water content in the solid. The treated water will flow to the end with a larger diameter. The solid and water enter the rotating ring 31 through the inlet holes 312 at both ends of the rotating ring 31, and are then thrown out through the outlet 313. The solid and water are discharged from the solid outlet 221 and liquid outlet 222 at the bottom of the lower shell 22, respectively.
[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
