Description

Technical Field

[0001] The utility model relates to the technical field of sludge dewatering equipment, in particular to an environmentally friendly and efficient sludge dewatering equipment. Background Art

[0002] Sludge is the inevitable product of sewage treatment plants and sewage stations after sewage treatment. Since the sludge will still be in a liquid flow state after concentration and digestion, its volume is still large and cannot be transported and disposed of. Therefore, dehydration equipment is usually used to dehydrate the sludge to reduce the volume of the sludge for subsequent transportation.

[0003] However, the existing sludge dewatering equipment usually uses a spiral pressing method to squeeze and dehydrate the sludge. During this process, the spiral blades on the screw need to be continuously pressed against the sludge, so that the sludge that has been squeezed dry is easy to stick to the spiral blades and is not easy to clean, resulting in residual sludge in the equipment and breeding bacteria, which is easy to pollute the surrounding environment and is not environmentally friendly. In addition, when the existing sludge dewatering equipment sends the dehydrated sludge out of the discharge port, due to the limited size of the discharge port, the sludge that is squeezed into blocks is easy to be blocked at the discharge port, which is not conducive to the rapid discharge of the dehydrated sludge, resulting in a slow dewatering efficiency of the equipment.

The cylindrical structure can cooperate with the spiral blades 3, so that the sludge can be squeezed and dehydrated in a closed and narrow space, thereby realizing the dehydration of the sludge, and the support base is used to support the cylindrical structure at the top so that it can be placed stably on the ground. At the same time, one side of the mud inlet cylinder 1 of the shell 2 is lower than one side of the mud outlet cylinder 12, so that the water squeezed out of the sludge can be discharged from different positions of the equipment with the sludge, thereby realizing the dehydration of the sludge. The top of the shell 2 is penetrated by the mud inlet cylinder 1, and a rotating motor 11 is fixedly installed at one end of the shell 2. The rotating motor 11 can drive the sleeve column 4 to rotate after power is turned on. The outer wall of the sleeve 4 is fixedly connected with the spiral blade 3, and a plurality of first through holes 16 are provided on one side of the sleeve 4. The inner wall of the sleeve 4 is provided with an inner tube 7, and a plurality of second through holes are provided on the outer wall of the sleeve 4. 17, the initial state of the first through hole 16 and the second through hole 17 is staggered arrangement, and the number of the first through holes 16 is twice the number of the second through holes 17, so that the sleeve 4 can continuously spray water from the first through hole 16 while rotating, so as to realize the flushing and cleaning of the sludge close to the spiral blade 3, and a connecting hose 5 is passed through one side wall of the embedded tube 7, and the end of the connecting hose 5 away from the embedded tube 7 is connected to the water pump, so that the connecting hose 5 can pass a high-speed water flow into the embedded tube 7, so that the water flow sprayed from the first through hole 16 of the sleeve 4 can rush to the spiral blade 3 and the inner wall of the shell 2, and a filter screen 8 is embedded on one side of the bottom end of the shell 2, and the function of the filter screen 8 is to filter the water squeezed out of the sludge, and a mud outlet is passed through the other side of the bottom end of the shell 2 The bottom of the mud discharge barrel 12 is provided with a movable plate 14, and the movable plate 14 can swing left and right at the bottom of the mud discharge barrel 12, so as to adjust the size of the bottom opening of the mud discharge barrel 12, so as to accelerate the discharge of the bulk sludge in the mud discharge barrel 12, and a side wall at the top of the movable plate 14 is fixedly connected with a paddle plate 13, and the function of the paddle plate 13 is to push the bulk sludge blocked in the mud discharge barrel 12, so that the volume of the bulk sludge can be broken and reduced under the push, so as to facilitate the rapid discharge of the sludge, and the top of the paddle plate 13 is fixedly connected with a scraper 18, which is made of silicone material, and the top is located at the junction of the mud discharge barrel 12 and the inner side of the shell 2, which can loosen the sludge blocked at the junction, so as to facilitate the rapid discharge of the sludge from the mud discharge barrel 12.

[0024] Specifically, a filtrate chamber 9 is opened at the bottom of the filter 8, and a drainage pipe 10 runs through one side wall of the filtrate chamber 9. The filtrate chamber 9 is communicated with the interior of the outer shell 2 through the filter 8. A disinfection structure is also provided in the filtrate chamber 9, which can perform preliminary disinfection on the sewage squeezed out of the sludge, thereby reducing the pollution caused to the environment by the filtrate discharged from the equipment, which is more environmentally friendly.

[0025] Furthermore, one end of the sleeve 4 is snap-connected with the output end of the rotating motor 11, and the sleeve 4 is rotatably connected to the outer shell 2 through the rotating motor 11. The first through hole 16 is opened on the outer wall of the sleeve 4. When the sleeve 4 is driven to rotate by the rotating motor 11, it can drive the spiral blade 3 to rotate, thereby realizing the squeezing and dehydration of the sludge by the spiral blade 3.

[0026] Furthermore, a first electric push rod 6 is fixedly installed at one end of the housing 2 away from the rotating motor 11, and the output end of the first electric push rod 6 is fixedly connected to the bottom end of the embedded tube 7, and the embedded tube 7 is movably embedded in the sleeve 4 through the first electric push rod 6. The embedded tube 7 needs to be pulled downward by the first electric push rod 6, so that the second through hole 17 on the embedded tube 7 can coincide with the first through hole 16 on the sleeve 4, thereby avoiding sludge from entering the second through hole 17 through the first through hole 16 and causing blockage of the embedded tube 7.

[0027] Furthermore, the interior of the connecting hose 5 is connected to the interior of the embedded tube 7, and the second through hole 17 is connected to the interior of the first through hole 16 through the embedded tube 7, so that the high-speed water flow entering the embedded tube 7 can enter the first through hole 16 through the second through hole 17, and then rush to the spiral blade 3 and the inner wall of the outer shell 2 through the first through hole 16, thereby achieving flushing and cleaning of the residual sludge on the spiral blade 3 and the inner wall of the outer shell 2.

[0028] Furthermore, a second electric push rod 15 is fixedly installed on a side wall of the outer shell 2 away from the discharge pipe 10, and the output end of the second electric push rod 15 is movably connected to the movable plate 14. The function of the second electric push rod 15 is to push the movable plate 14 to swing left and right at the bottom of the mud discharge barrel 12, thereby realizing the adjustment of the size of the bottom opening of the mud discharge barrel 12, which is beneficial to the rapid discharge of dehydrated sludge from the mud discharge barrel 12.

[0029] Furthermore, the movable plate 14 is movably connected to the mud discharge barrel 12 through the second electric push rod 15, and the paddle plate 13 and the scraper 18 are movably connected to the mud discharge barrel 12 through the movable plate 14. Driven by the movable plate 14, the paddle plate 13 and the scraper 18 can stir the lumpy sludge blocked in the mud discharge barrel 12, thereby accelerating the discharge of the dewatered sludge and improving the dewatering efficiency of the sludge dewatering equipment.

[0030] The method of using the present embodiment is as follows: when using the present environmentally friendly and efficient sludge dewatering equipment, the present equipment needs to be connected to an external power supply first, and then the rotating motor 11 is started, so that the rotating motor 11 drives the sleeve 4 to rotate, and drives the spiral blades 3 to rotate in the inner cavity of the outer shell 2, and then the sludge can be poured into the mud inlet tube 1, so that the sludge enters the rotating spiral blades 3 and is squeezed and dehydrated. At this time, the squeezed sewage will pass through the filter screen 8 and enter the filtrate cavity 9 for preliminary disinfection and then be discharged from the equipment through the drain pipe 10. Then, the sludge squeezed out of the water will be brought to the mud outlet tube 12 by the spiral blades 3 for discharge. When the mud outlet tube 12 is blocked, the second electric push rod 15 can be started, so that the second electric push rod 15 pushes the movable plate 14 to swing left and right at the bottom of the mud outlet tube 12, so that the movable plate 14 drives the paddle plate 13 and the scraper 18 to remove the blocked block in the mud outlet tube 12. The sludge is pushed and squeezed to break the large-volume block sludge, and then quickly discharged from the mud discharge tube 12. When it is necessary to clean the inside of the equipment, the water pump connected to the connecting hose 5 is turned on to allow high-speed water flow to flow into the connecting hose 5. Then the first electric push rod 6 is started to pull the embedded tube 7 down a distance from the sleeve 4, so that the second through hole 17 on the outer wall of the embedded tube 7 and the first through hole 16 on the sleeve 4 can coincide with each other when the sleeve 4 rotates. Then, when the first through hole 16 and the second through hole 17 coincide with each other, the water flow will pass through the second through hole 17 and the first through hole 16 from the inside of the embedded tube 7 to the outer wall of the spiral blade 3 and the inner wall of the outer shell 2, and the sludge close to the outer wall of the spiral blade 3 and the inner wall of the outer shell 2 is flushed, so that the sludge remaining in the equipment is reduced, and it is not easy for bacteria to grow in the equipment due to the residual sludge, which is more environmentally friendly.
