Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a sludge drying device. Background Art

[0002] Sludge refers to a mixture of water, solid matter and colloidal substances separated by sedimentation, filtration, centrifugation and other methods during wastewater treatment or industrial production. Sludge usually contains a large amount of organic matter, inorganic matter, microorganisms, heavy metals, etc. Sludge is generally compressed and dehydrated by equipment such as compressors and dehydrators to reduce its water content and turn it into a solid state. After drying, the dried sludge can be used in many aspects. The comprehensive utilization of sludge can reduce environmental pollution, reduce energy consumption, and reduce production costs. It is of great significance in the context of sustainable development.

[0003] The centrifugal dewatering machine uses centrifugal force to separate the water in the sludge. This equipment has a fast processing speed, occupies a small area and is easy to operate. It is suitable for difficult-to-handle sludge. However, its screen drum is easily blocked and needs frequent manual cleaning, which leads to high labor maintenance costs, so it needs to be improved. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention solves the technical problems thereof by adopting a technical solution as follows: a sludge drying device, comprising a drainage shell, a drying device is arranged inside the drainage shell, auxiliary devices are symmetrically arranged on the front and rear sides of the drainage shell, the drying device comprises a drainage net shell, a shaft device is arranged in the middle of the inner cavity of the drainage net shell, and a sludge treatment cylinder is arranged in the middle of the outer surface of the shaft device;

[0006] The right side of the outer surface of the joint rotating rod is fixedly connected with a control pull box, and the inner cavity of the control pull box is symmetrically provided with a control pull plate, and the end of the control pull plate at the back away from the control pull box is fixedly connected to the outer surface of the connecting shell, and the end of the control pull plate at the front away from the control pull box is fixedly connected to the outer surface of the closed front plate. The shaft rod device includes a through-guide rod, and the upper and lower sides of the outer surface of the through-guide rod are sleeved with compression sleeves, and the inner cavity of the compression sleeve is fixedly connected with a vertical push rod, and the end of the vertical push rod away from the through-guide rod is fixedly connected with a wall-attached push box, and the wall-attached push box can push the compression sleeve through the vertical push rod, so that the compression sleeve slides up and down along the through-guide rod, thereby driving the sludge treatment cylinder as a whole to slide along the through-guide rod, and the vertical pull cylinder can use the through-guide rod in the middle as a guiding shaft rod to drive the pressure cover plates on the upper and lower sides to slide up and down.

[0007] The upper and lower ends of the through-guide rod are extended to the outside of the water filter housing through the through-port, the middle of the inner wall of the vertical pull tube is fixedly connected to the middle of the outer surface of the through-guide rod, the axis of the inner cavity of the pressure cover plate is slidably connected to the outer surface of the through-guide rod, and the end of the compression sleeve away from the vertical push rod is fixedly connected to the axis of the outer surface of the water filter housing. There are two wall-attached push boxes, the outer surface of the wall-attached push box is fixedly connected to the axis of the outer surface of the drainage net shell, the end of the vertical push rod away from the compression sleeve extends to the outside of the drainage net shell through the through-port, and the end of the vertical push rod away from the compression sleeve is slidably connected to the inner cavity of the drainage net shell through the through-port.

[0008] The drainage shell includes an outer sealing shell, which is formed by merging the outer sealing shells on the front and rear sides, so when loading and unloading, the outer sealing shell can be pulled open to open the internal sludge treatment cylinder, and the front and rear sides of the inner cavity of the outer sealing shell are symmetrically provided with rotating rollers, and the lower part of the inner wall of the outer sealing shell is fixedly connected with an arc-shaped partition, and the two sides of the inner cavity of the arc-shaped partition are symmetrically provided with drainage detection rods, and the middle part of the lower surface of the arc-shaped partition is fixedly connected with a water quality analyzer, and the water separated from the sludge will flow downward through the outer sealing shell, and then continue to be discharged through the drainage detection rod, and when the water is discharged, it will be absorbed by the absorption core inside the drainage detection rod, and real-time detection work will be performed by the water quality analyzer. The inner cavity of the rotating roller is rotatably connected to the inner cavity of the outer sealing shell through a rotating rod, the outer surface of the rotating roller is rollingly connected to the outer surface of the drainage net shell, and the outer surface of the drainage detection rod is rotatably connected to the inner cavity of the arc-shaped partition through a rotating groove.

The number of the auxiliary equipment is two, the outer surface of the inner sliding pan is slidably connected to the inner wall of the drainage net shell, the end of the drying pipe away from the inner sliding pan extends to the outside of the outer sealing shell, and the bottom of the external bracket is fixedly connected to the ground.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. This device is further improved on the basis of the centrifugal dewatering machine. When the sludge is centrifugally rotated to remove the internal sewage, the sludge treatment cylinder will also reciprocate along the guide rod penetrating the axis, so that the sludge squeezed by the pressure cover will not always fit the inner wall of the water filter shell, thereby causing the water filter shell to be easily blocked. It ensures that the water inside the sludge can be discharged normally, avoiding the problem that the water filter shell is easily blocked and requires frequent manual cleaning, resulting in high labor maintenance costs.

[0012] 2. The amount of sludge added to the sludge treatment cylinder each time is small, and the interior of the sludge treatment cylinder will not be completely filled. This will cause the sludge to oscillate repeatedly inside the cylinder during the centrifugal dehydration of the sludge treatment cylinder, making it difficult for the sludge to throw out the water inside. Therefore, after the sludge is added to the sludge treatment cylinder, the vertical pulling cylinder will compress the space where the sludge is located by pushing the pressure covers on both sides, so that the sludge can perform effective centrifugal movement with the cylinder, thereby allowing the water inside the sludge to easily escape, avoiding the problem of sludge oscillation.

[0013] 3. When the water slides downward along the inner wall of the outer sealing shell, it will definitely pass through the drainage detection rod, and then the drainage detection rod will absorb a small amount of water through the inner core for collection. Then the water quality analyzer will analyze the impurity content in the water. If the impurity content is normal, it means that the sludge of the device has been effectively dehydrated. Otherwise, there may be a problem of sludge leakage, which needs to be troubleshooted to avoid ineffective sludge treatment and thus serious water pollution.

[0014] 4. After the sludge is dehydrated, the drying pipe heats and dries the area where the sludge treatment cylinder is located, so that the more viscous sludge can remove the last bit of water and form a drier mud body. Under the centrifugal shaking of the sludge treatment cylinder, the mud body will be further broken into fine mud, and finally the dried sludge will be obtained. Therefore, when taking out the internal mud body, the sludge will not have a large amount of lumps, resulting in a large amount of water in the agglomerated sludge, which leads to the problem of incomplete sludge drying.

[0025] The sludge treatment cylinder 23 includes a connecting shell 231, the right end of the connecting shell 231 is rotatably connected to a joint rotating rod 232, the outer surface of the joint rotating rod 232 is rotatably connected to a closed front plate 233, the upper and lower sides of the outer surface of the connecting shell 231 are fixedly connected to a water filter shell 234, the inner wall of the water filter shell 234 is slidably connected to a pressure cover plate 236, the pressure cover plates 236 on both sides can fit the inner wall of the connecting shell 231 and slide into the interior of the water filter shell 234, and a vertical pull cylinder 235 is fixedly connected to the axis of the inner cavity of the pressure cover plate 236.

[0026] A control pull box 24 is fixedly connected to the right side of the outer surface of the joint rotating rod 232, and a control pull plate 25 is symmetrically arranged in the inner cavity of the control pull box 24, and the end of the back control pull plate 25 away from the control pull box 24 is fixedly connected to the outer surface of the connecting shell 231, and the end of the front control pull plate 25 away from the control pull box 24 is fixedly connected to the outer surface of the closed front plate 233. The shaft rod device 22 includes a through guide rod 221, and compression sleeves 222 are sleeved on the upper and lower sides of the outer surface of the through guide rod 221. The inner cavity of the compression sleeve 222 is fixedly connected with a vertical push rod 223, and the end of the vertical push rod 223 away from the through guide rod 221 is fixedly connected with a wall push box 224. The wall push box 224 can push the compression sleeve 222 through the vertical push rod 223, so that the compression sleeve 222 slides up and down along the through guide rod 221, thereby driving the sludge treatment cylinder 23 as a whole to slide along the through guide rod 221. The vertical pull cylinder 235 can use the through guide rod 221 in the middle as a guiding shaft rod to drive the pressure cover plates 236 on the upper and lower sides to slide up and down.

[0027] Both upper and lower ends of the penetrating guide rod 221 extend to the outside of the water filter housing 234 through the through opening, the middle of the inner wall of the vertical pull tube 235 is fixedly connected to the middle of the outer surface of the penetrating guide rod 221, the axis of the inner cavity of the pressure cover plate 236 is slidably connected to the outer surface of the penetrating guide rod 221, and the end of the compression sleeve 222 away from the vertical push rod 223 is fixedly connected to the axis of the outer surface of the water filter housing 234. There are two wall-attached push boxes 224, the outer surface of the wall-attached push boxes 224 is fixedly connected to the axis of the outer surface of the drainage net shell 21, the end of the vertical push rod 223 away from the compression sleeve 222 extends to the outside of the drainage net shell 21 through the through opening, and the end of the vertical push rod 223 away from the compression sleeve 222 is slidably connected to the inner cavity of the drainage net shell 21 through the through opening.

[0028] When using the device to treat the sludge that has just been filtered, pull open the drainage shells 1 on the front and rear sides, and then open the sludge treatment cylinder 23. At this time, the vertical pull cylinder 235 is contracted to the shortest state, that is, the pressure cover plates 236 on the upper and lower sides are fitted together, and then fill the sludge in the upper and lower areas of the sludge treatment cylinder 23. Then, close the front closed front plate 233, and reinforce the control pull plate 25 through the side control pull box 24, so that the closed front plate 233 is fixed and limited, close the drainage shell 1, and then prepare for drying.

[0029] The vertical pull cylinder 235 in the middle pushes the pressure cover plates 236 on both sides in opposite directions, and then the pressure cover plates 236 push the sludge on both sides toward the side close to the wall push box 224. After the sludge is compressed, the residual water inside will enter the interior of the drainage housing 1 through the water filter housing 234, and then the pressure cover plates 236 will be retracted, and the above movement will be repeated;

[0030] The rotating rollers 12 on both sides of the inner wall of the outer sealing shell 11 will drive the drainage net shell 21 to rotate axially, thereby throwing out the water inside the sludge on the upper and lower sides of the sludge treatment cylinder 23, and entering the interior of the drainage outer shell 1 through the filter port of the drainage net shell 21 to achieve collection;

[0031] The wall-attached push boxes 224 on the upper and lower sides of the shaft device 22 will drive the sludge treatment cylinder 23 to slide back and forth up and down along the outer surface of the guide rod 221 through the vertical push rod 223, so that the sludge on the inner wall of the sludge treatment cylinder 23 and the mesh port of the water filter shell 234 are shaken off to the inside of the cylinder, thereby effectively reducing the problem of blockage of the mesh port of the water filter shell 234 due to sludge accumulation.

[0032] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of Example 1, the drainage shell 1 includes an outer sealing shell 11, and the device is formed by merging the outer sealing shells 11 on the front and rear sides, so the outer sealing shell 11 can be pulled open when loading and unloading, and the internal sludge treatment cylinder 23 is opened. The front and rear sides of the inner cavity of the outer sealing shell 11 are symmetrically provided with turning rollers 12, and the lower part of the inner wall of the outer sealing shell 11 is fixedly connected with an arc-shaped partition 13, and drainage detection rods 14 are symmetrically provided on both sides of the inner cavity of the arc-shaped partition 13. A water quality analyzer 15 is fixedly connected to the middle part of the lower surface of the arc-shaped partition 13. The water separated from the sludge will flow downward through the outer sealing shell 11, and then continue to be discharged through the drainage detection rod 14. When the water is discharged, it will be absorbed by the absorption core inside the drainage detection rod 14, and real-time detection work will be performed by the water quality analyzer 15.

[0033] The auxiliary device 3 includes an inner sliding pan 31, the inner cavity of the inner sliding pan 31 is symmetrically provided with a drying through pipe 32, a lateral thruster 33 is fixedly connected to the axis of the inner cavity of the inner sliding pan 31, and an external bracket 34 is rotatably connected to the axis of the outer surface of the lateral thruster 33. There are two auxiliary devices 3, the outer surface of the inner sliding pan 31 is slidably connected to the inner wall of the drainage net shell 21, the drying through pipe 32 extends to the outside of the outer sealing shell 11 at one end away from the inner sliding pan 31, and the bottom of the external bracket 34 is fixedly connected to the ground.

[0034] When the water slides downward along the inner wall of the outer sealing shell 11, it will definitely pass through the drainage detection rod 14. Then the drainage detection rod 14 absorbs a small amount of water through the inner core for collection. Then the water quality analyzer 15 analyzes the impurity content in the water. If the impurity content is normal, it means that the sludge of the device has been effectively dehydrated. Otherwise, there may be a problem of sludge leakage, which needs to be troubleshooted.

[0035] After the sludge is dehydrated, the lateral thrusters 33 on both sides will push the inner sliding plate 31 to the side close to the sludge treatment cylinder 23, and then the drying pipes 32 on the upper and lower sides will heat and dry the area where the sludge treatment cylinder 23 is located, so that the more viscous sludge can remove the final moisture and form a relatively dry mud body. Under the centrifugal shaking action of the sludge treatment cylinder 23, the mud body will be further broken into fine mud, and finally the dried sludge will be obtained.
