Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering, and in particular to a multiple circular plate type sludge dewatering machine and an operating method thereof. Background Art

[0002] The multiple circular plate sludge dewatering machine is a new type of energy-saving and environmentally friendly equipment with many advantages, including energy conservation, water conservation, small size, ability to process oily sludge, continuous automatic operation, and easy maintenance. The multiple circular plate sludge dewatering machine consists of a box-type main unit equipped with two rows of filter bodies, each of which is fixed to the main shaft and consists of a stack of corrugated stainless steel circular plates. During operation, the flocculated sludge flowing into the main unit is first filtered and then concentrated as it moves forward. As the gap between the upper and lower filter bodies gradually decreases, the advancing sludge is compressed and dehydrated, and the filter cake is finally discharged from the side of the box-type main unit. The multiple circular plate sludge dewatering machine uses the dehydration principles of "gravity filtration" plus "extrusion" to discharge the sludge filter cake like a sponge, forming a thick layer with a uniform internal texture.

During the use of existing sludge dewatering machines, the sludge contains a large amount of water, which causes the sludge volume to increase, increasing the processing burden of the dewatering device, thereby reducing the sludge dewatering efficiency; 2. During the use of the existing sludge dewatering machine, due to the freezing pretreatment of the sludge, some ice crystals are easily attached to the equipment. Over time, the ice crystals accumulate on each other, making the volume of the ice crystals larger, which makes the sludge agglomerate and difficult to discharge smoothly. Summary of the Invention

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figures 1 to 11 As shown, a multiple circular plate sludge dewatering machine described in an embodiment of the present invention includes a processing body 1, a sealing cover 2 is fixedly connected to the center of the top of the processing body 1, and a feed pipe 3 is fixedly connected to one end of the top of the processing body 1 close to the sealing cover 2, and a first motor 4 is fixedly connected to one end of the top of the sealing cover 2, and the output end of the first motor 4 is fixedly connected to a gear rod 5, and the bottom of the gear rod 5 is rotatably connected to the top of the processing body 1, one side of the outer wall of the gear rod 5 is engaged with a toothed disk 6, and the bottom of the toothed disk 6 is fixedly connected to a linkage pipe 7, the top of one side of the outer wall of the linkage pipe 7 is rotatably connected to the center of the top of the processing body 1, and both ends of the middle part of the outer wall of the linkage pipe 7 are fixedly connected to a stirring frame 8, one end of the heating pipe 31 is fixedly connected to a dehydration bin 36, and a number of second motors 37 are fixedly connected to the outer wall of the dehydration bin 36, and the output end of the second motor 37 is fixedly connected to a filter body 38, and one end of the filter body 38 is rotatably connected to one side of the inner wall of the dehydration bin 36.

[0021] During operation, the sludge is poured into the processing body 1 along the feed pipe 3, and the first motor 4 set at one end of the top of the cover 2 is started. The first motor 4 is used to drive the gear rod 5 set at its output end, and the gear rod 5 drives the linkage pipe 7 set at its bottom to rotate through the gear plate 6, so that the stirring racks 8 set at both ends of the middle of the outer wall of the linkage pipe 7 are used to stir the sludge. In this process, the air pump 9 set at one end of the top of the processing body 1 is started, and the air pump 9 is used to send cold air into the deflector 10, and the deflector 10 is used to send the cold air into the ventilation plate 1 through the guide pipe 11 set at one end of the bottom. 2, the cold air is discharged from the exhaust pipe 16 through the ventilation plate 12, so that the cold air contacts the sludge. Since an arc plate 25 is provided at one end of the outer wall of the exhaust pipe 16, when the linkage pipe 7 drives the arc plate 25 to rotate, not only the sludge can be stirred, but also when the sludge passes through the surface of the arc plate 25, due to the high viscosity of the sludge itself, a cavity is formed behind the arc plate 25, so that the cold air discharged from the exhaust pipe 16 contacts the sludge fully, so that the water in the sludge forms ice crystals, and at the same time the volume of the sludge expands, destroying the colloidal structure and cell wall in the sludge, thereby achieving To strip off the moisture of organic matter in the sludge, the linkage pipe 7 drives the stirring frame 8 and the curved plate 25 to rotate continuously, so that the sludge in the treatment body 1 is difficult to condense with each other and form an ice-sandwich shape. At this time, the electric telescopic rod 34 set at the center of the bottom of the treatment body 1 is started, so that the electric telescopic rod 34 drives the blocking block 35 set at its output end to break away from the discharge port 30 set at both ends of the bottom of the treatment body 1, so that the ice-sandwich-like sludge flows along the discharge port 30 into the heating pipe 31, and the electric heating leakage net 32 set in the middle of one side of the inner wall of the heating pipe 31 is started to heat the ice-sandwich-like sludge. , so that the ice crystals in the sludge melt and evaporate quickly, and most of the free water is discharged through the exhaust valve 33 through the evaporated water vapor, and the sludge passes through the electric heating filter 32 and flows into the dehydration bin 36 along the arc groove set at the bottom of the heating tube 31. At this time, several second motors 37 are started, and the second motors 37 drive the filter body 38 to perform secondary dehydration on the colloidal sludge entering the dehydration bin 36, further solving the problem that in the use of traditional sludge dehydrators, the sludge contains a large amount of water, which causes the sludge volume to increase, increases the processing burden of the dehydration device, and thus causes the sludge dehydration efficiency to decrease.

[0022] One end of the top of the processing body 1 is fixedly connected to an air pump 9, and the output end of the air pump 9 is fixedly connected to a deflector 10, and one end of the bottom of the deflector 10 is fixedly connected to a guide pipe 11, one end of the guide pipe 11 is fixedly connected to a vent plate 12, and the bottom of the vent plate 12 is rotatably connected to a shaft exhaust plate 13, and the bottom of the shaft exhaust plate 13 is fixedly connected to a plurality of vent pipes 14, one end of the vent pipe 14 is fixedly connected to a limit pipe 15, and one side of the outer wall of the limit pipe 15 is rotatably connected to an exhaust pipe 16, and the exhaust pipe 16 is fixedly connected to the exhaust pipe 16. The inner wall of the air pipe 16 is fixedly connected with a blocking block 17, one side of the outer wall of the exhaust pipe 16 is rotatably connected to the inner cavity of the linkage pipe 7, and the outer wall of the exhaust pipe 16 is fixedly connected to one end of the linkage pipe 7, and the bottom of the bevel gear 18 is engaged with a bevel gear 19, and the inner wall of the bevel gear 19 is fixedly connected with a support column 20, the bottom of the support column 20 is fixedly connected to the center of the bottom of the inner wall of the processing body 1, and the top of the support column 20 is fixedly connected to the bottom of the deflector 10, and the outer wall of the linkage pipe 7 is close to One side of the stirring frame 8 is fixedly connected to a plurality of support plates 21, and one side of the outer wall of the support plate 21 penetrates one side of the outer wall of the exhaust pipe 16, and the upper and lower ends of the outer wall of the support plate 21 are fixedly connected to a plurality of limit frames 22, and the inner cavity of the support plate 21 is slidably connected to a plurality of elastic telescopic frames 23, one end of the elastic telescopic frame 23 is fixedly connected to an arc block 24, and the outer wall of the arc block 24 is close to the side of the elastic telescopic frame 23 and overlaps one side of the outer wall of the support plate 21, and the upper and lower ends of the outer wall of the arc block 24 are slidably connected to the arc plate 25, and one end of the inner cavity of the arc-shaped plate 25 is slidably connected to the outer wall of the limit frame 22, and guide grooves 26 are provided at both ends of the inner cavity of the processing body 1, and the upper and lower ends of the inner wall of the guide groove 26 are fixedly connected with a wave plate 27, and the surface of the wave plate 27 is slidably connected with a moving column 28, one end of the moving column 28 is fixedly connected to one end of the outer wall of the arc-shaped plate 25, and the side of the inner wall of the guide groove 26 close to the wave plate 27 is slidably connected to the arc-shaped partition plate 29, and one side of the outer wall of the arc-shaped partition plate 29 overlaps the outer wall of the arc-shaped plate 25.

[0023] During operation, a plurality of support plates 21 are provided on one side of the outer wall of the linkage pipe 7 close to the stirring frame 8, and a plurality of limit frames 22 are provided at the upper and lower ends of the outer wall of the support plate 21. The limit frames 22 are used to limit the arc plate 25, so that the linkage pipe 7 drives the stirring frame 8 to rotate, and drives the arc plate 25 to stir the sludge. Since an exhaust pipe 16 is provided on one side of the outer wall of the support plate 21, and the outer wall of the exhaust pipe 16 passes through the linkage pipe 7, when the linkage pipe 7 rotates, an air pump 9 is provided at one end of the top of the processing body 1, and the air pump 9 is used to send cold air into the deflector 10, and the cold air is sent into the ventilation plate 12 along the guide pipe 11 provided at the bottom thereof through the deflector 10, and the rotating shaft exhaust piece 13 provided at the bottom of the ventilation plate 12 is used. , so that the cold air follows the shaft exhaust plate 13, enters the several vent pipes 14 set at its bottom, and is discharged into the limiting pipe 15 along the vent pipe 14, and the cold air is discharged from the exhaust pipe 16 through the limiting pipe 15 into the cavity between the arc plates 25. Since the surface of the arc plates 25 is streamlined, when the sludge is stirred, the sludge passes through the surface of the arc plates 25, causing the sludge to flow around and separate to form a low-pressure cavity, and the cold air in the cavity of the arc plates 25 enters the low-pressure cavity, condensing the water in the sludge into ice crystals, causing the sludge volume to expand while destroying the colloidal structure and cell wall in the sludge, reducing the sludge adhesion while stripping the organic matter in the water. By setting a barrier block 17 on the inner wall of the exhaust pipe 16, when the sludge is injected into the treatment body 1 When the blocking block 17 is used, the inner diameter of the exhaust pipe 16 is reduced, and under the influence of air pressure, it is difficult for the sludge to flow into the exhaust pipe 16. A bevel gear 18 is provided on the outer wall of the exhaust pipe 16 near one end of the linkage pipe 7. Since a support column 20 is provided at the center of the bottom of the inner wall of the processing body 1, and a bevel gear disk 19 is provided on the outer wall of the support column 20, when the linkage pipe 7 drives the exhaust pipe 16 to rotate at a uniform speed, the bottom of the bevel gear 18 is meshed with one side of the outer wall of the bevel gear disk 19, so that the exhaust pipe 16 rotates at a uniform speed in the inner cavity of the linkage pipe 7. Under the influence of centrifugal force, the sludge attached to the exhaust pipe 16 is thrown out, and it is avoided that during the stirring process of the sludge, part of the sludge follows the cavity in the arc plate 25 and adheres to the exhaust pipe 1 6, resulting in the blockage of the exhaust pipe 16. During the low-temperature ice crystallization of the sludge, although the sludge in the treatment body 1 is always in a stirring state and it is difficult to condense large ice crystals, the cold air discharged from the exhaust pipe 16 contacts the sludge through the cavity of the curved plate 25, which easily causes ice crystals to form on the surface of the curved plate 25, thereby making it difficult for the curved plate 25 to separate the sludge from the surrounding low-pressure cavity. Not only is it difficult for the cold air to fully contact the sludge, but ice crystals are also likely to continuously condense on the surface of the curved plate 25, thereby generating large ice blocks. For this purpose, guide grooves 26 are provided at both ends of the inner cavity of the treatment body 1, and wave plates 27 are provided at the upper and lower ends of the inner wall of the guide groove 26. A movable column 28 is provided at one end of the outer wall of the curved plate 25.As the curved plates 25 rotate under the pull of the linkage pipe 7, the movable columns 28 slide on the surface of the wave plates 27. The curved plates 25, constrained by the limiter 22, vibrate at a high frequency and small amplitude. During this period, the curved blocks 24 positioned between the curved plates 25 are continuously squeezed. The elastic expansion brackets 23 at one end of the curved blocks 24 reposition the curved plates 25 at the upper and lower ends of the outer walls of the curved blocks 24, thereby preventing ice crystals from freezing and adhering to the surfaces of the curved plates 25. This solves the problem of ice crystals easily adhering to the surface of the curved plates 25 during the freezing pretreatment of the sludge during use. Over time, the ice crystals accumulate, increasing their size and making it difficult to discharge the sludge.

[0024] Discharge ports 30 are provided at both ends of the bottom of the processing body 1, and a heating pipe 31 is fixedly connected to the bottom of the processing body 1. An electric heating leakage net 32 is fixedly connected to the middle of one side of the inner wall of the heating pipe 31, and an exhaust valve 33 is fixedly connected to one end of the top of the heating pipe 31. An electric telescopic rod 34 is fixedly connected to the center of the bottom of the processing body 1, and a blocking block 35 is fixedly connected to the output end of the electric telescopic rod 34, and the two ends of the top of the blocking block 35 are slidably connected to the inner wall of the discharge port 30.

[0025] During operation, by setting discharge ports 30 at both ends of the bottom of the processing body 1, when the sludge freezing and wall breaking process is completed, the electric telescopic rod 34 set at the center of the bottom of the processing body 1 is started, and the blocking block 35 set at its output end is separated from the discharge port 30. Since the surface of the blocking block 35 has an arc, the ice-sandwich-like sludge flows into the heating tube 31 along the gap between the blocking block 35 and the discharge port 30. By setting an electric heating filter 32 in the middle of one side of the inner wall of the heating tube 31, the ice-sandwich-like sludge falling on the surface of the electric heating filter 32 is quickly melted, and the ice crystals in the sludge evaporate to form water vapor, which is discharged through the exhaust valve 33 set at one end of the top of the heating tube 31. The remaining sludge and non-aqueous solution fall into the bottom of the heating tube 31 along the electric heating filter 32, and are discharged into the dehydration bin 36 along the arc groove set at the bottom of the heating tube 31 for further dehydration treatment.

[0026] An operating method for multiple circular plate type sludge dewatering, which uses the above-mentioned multiple circular plate type sludge dewatering machine, is as follows: S1: The sludge is poured into the treatment body 1 through the feed pipe 3 and stirred by the stirring frame 8. The air pump 9 is started and the cold air is discharged through the exhaust pipe 16 by the rotating shaft exhaust plate 13, so that the water in the sludge forms ice crystals. The sludge containing ice crystals is then fed into the heating pipe 31. The ice crystals in the sludge are evaporated and gasified by the electric heating filter 32. Finally, the sludge is discharged into the dehydration bin 36 for further dehydration treatment. S2: By providing guide grooves 26 at both ends of the inner cavity of the treatment body 1 and providing wave plates 27 at the upper and lower ends of the inner wall of the guide groove 26, when the curved plate 25 rotates under the traction of the linkage pipe 7, the movable column 28 slides on the surface of the wave plate 27 and vibrates at a high frequency and a small amplitude, thereby preventing the problem of ice crystals generated by sludge freezing adhering to the surface of the curved plate 25; S3: A plurality of second motors 37 are started, and the second motors 37 drive the filter bodies 38 to perform secondary dehydration on the colloidal sludge entering the dehydration bin 36 .

[0027] The following specifically describes the working principle of the multiple circular plate sludge dewatering machine and its operation method.

[0028] like Figures 1-11As shown, the sludge is poured into the treatment body 1 along the feed pipe 3, and the first motor 4 provided at one end of the top of the cover 2 is started. The first motor 4 is used to drive the gear rod 5 provided at its output end, and the gear rod 5 drives the linkage pipe 7 provided at its bottom to rotate through the toothed disk 6, so that the stirring racks 8 provided at both ends of the middle of the outer wall of the linkage pipe 7 are used to stir the sludge. In this process, the air pump 9 provided at one end of the top of the treatment body 1 is started, and the air pump 9 is used to send cold air into the deflector 10, and the deflector 10 is used to send the cold air into the ventilation plate 1 through the guide pipe 11 provided at one end of the bottom thereof. 2, the cold air is discharged from the exhaust pipe 16 through the ventilation plate 12, so that the cold air contacts the sludge. Since an arc plate 25 is provided at one end of the outer wall of the exhaust pipe 16, when the linkage pipe 7 drives the arc plate 25 to rotate, not only the sludge can be stirred, but also when the sludge passes through the surface of the arc plate 25, due to the high viscosity of the sludge itself, a cavity is formed behind the arc plate 25, so that the cold air discharged from the exhaust pipe 16 contacts the sludge fully, so that the water in the sludge forms ice crystals, and at the same time the volume of the sludge expands, destroying the colloidal structure and cell wall in the sludge, thereby achieving To strip off the moisture of organic matter in the sludge, the linkage pipe 7 drives the stirring frame 8 and the curved plate 25 to rotate continuously, so that the sludge in the treatment body 1 is difficult to condense with each other and form an ice-sandwich shape. At this time, the electric telescopic rod 34 set at the center of the bottom of the treatment body 1 is started, so that the electric telescopic rod 34 drives the blocking block 35 set at its output end to break away from the discharge port 30 set at both ends of the bottom of the treatment body 1, so that the ice-sandwich-like sludge flows along the discharge port 30 into the heating pipe 31, and the electric heating leakage net 32 set in the middle of one side of the inner wall of the heating pipe 31 is started to heat the ice-sandwich-like sludge. , so that the ice crystals in the sludge melt and evaporate quickly, and most of the free water is discharged through the exhaust valve 33 through the evaporated water vapor, and the sludge passes through the electric heating filter 32 and flows into the dehydration bin 36 along the arc groove set at the bottom of the heating tube 31. At this time, several second motors 37 are started, and the second motors 37 drive the filter body 38 to perform secondary dehydration on the colloidal sludge entering the dehydration bin 36, further solving the problem that in the use of traditional sludge dehydrators, the sludge contains a large amount of water, which causes the sludge volume to increase, increases the processing burden of the dehydration device, and thus causes the sludge dehydration efficiency to decrease.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
