DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] The present invention provides a deodorization and purification device for sewage sludge pretreatment, such as Figures 1 to 6As shown, it includes a treatment pool 1, the interior of the treatment pool 1 is provided with a paving assembly for paving the sludge inside the treatment pool 1, and the exterior of the treatment pool 1 is provided with a deodorizing assembly for deodorizing and purifying the sludge;

[0034] The deodorizing component includes: a bracket 2, a connecting rod 3, a grid 4, a cloth cover 5, activated carbon 6 filled in the cloth cover 5, a switching component for driving the cloth cover 5 to move, and a lifting component for driving the bracket 2 to rise and fall. The activated carbon 6 is in granular form and filled in the cloth cover 5.

[0035] The connecting rod 3 is fixedly connected to the middle of the bottom end of the bracket 2 , and the other end of the connecting rod 3 is fixedly connected to the middle of the top end of the grid 4 , and the cloth cover 5 goes around the bottom of the grid 4 .

[0036] When in use, pour the sludge into the treatment pool 1, and use the paving assembly to flatten the sludge so that the thickness of the sludge is 20CM. Then, the lifting assembly drives the bracket 2 to descend, so that the connecting rod 3, the grid 4, and the cloth cover 5 are lowered, so that the cloth cover 5 located under the grid 4 is embedded in the sludge for 2CM, and then the bracket 2 is stopped from descending, and the activated carbon 6 in the cloth cover 5 absorbs the odor emitted by the sludge to deodorize and purify the sludge. After a period of time, the lifting assembly drives the bracket 2 to rise, so that the connecting rod 3, the grid 4, and the cloth cover 5 are raised. The cloth cover 5 is lifted up, so that the cloth cover 5 leaves the sludge, and then the switching component drives the cloth cover 5 to move, moving with the used activated carbon 6 and leaving the top of the treatment pool 1. The unused activated carbon 6 moves to the top of the treatment pool 1, and then the lifting component drives the bracket 2 to descend, and the cloth cover 5 with the unused activated carbon 6 is embedded in the sludge to continue deodorizing. The above operation is repeated at intervals, so that the activated carbon 6 on the sludge can be continuously replaced, so as to avoid the activated carbon 6 being saturated and not replaced, which affects the treatment effect of the sludge.

[0037] like Figure 1 and Figure 4 As shown, the switching assembly includes: a winding roller 7, a first motor 8, and a screw 25;

[0038] There are two winding rollers 7, and a pair of winding rollers 7 are rotatably installed on both sides of the bottom of the bracket 2. There are two first motors 8, and the two first motors 8 are symmetrically fixed on the outside of the bracket 2. One end of the output shaft of the first motor 8 is fixedly connected to one end of the winding roller 7. Both ends of the cloth cover 5 are fixedly connected to the two winding rollers 7 by screws 25. The cloth cover 5 is wound on one side of the winding roller 7. The first motor 8 is a motor with an output shaft locking function.

[0039] Start the first motor 8 on one side to rotate its output shaft with the connected winding roller 7, thereby winding the cloth cover 5. At the same time, start the first motor 8 on the other side to rotate its output shaft with the connected winding roller 7, so that the cloth cover 5 is released, and the cloth cover 5 moves with the activated carbon 6 to switch the used activated carbon 6 above the treatment pool 1 to the unused activated carbon 6. When the activated carbon 6 in the entire cloth cover 5 is used up, remove the screw 25 to separate the cloth cover 5 from the winding roller 7, thereby facilitating the replacement of the cloth cover 5 with new activated carbon 6.

[0040] like Figure 1 As shown, the lifting assembly includes: a bottom plate 9, a limit rod 10, a carrier plate 11, a screw rod 12, and a second motor 13;

[0041] The number of base plates 9 is four, and the base plates 9 are fixedly mounted on the outside of the treatment pool 1. The limiting rod 10 is fixedly mounted on the top of the base plate 9. The number of carrier plates 11 is two and symmetrically fixedly mounted on the outside of the treatment pool 1. The screw rod 12 is rotatably mounted on the carrier plate 11. The number of second motors 13 corresponds to the number of carrier plates 11. The second motor 13 is fixedly mounted on the outside of the treatment pool 1. The top of the output shaft of the second motor 13 is fixedly connected to the bottom of the corresponding screw rod 12. The bracket 2 is slidably sleeved on the outside of multiple limiting rods 10, and the bracket 2 is threadedly connected to the screw rod 12.

[0042] Start the second motor 13 to make its output shaft rotate forward with the screw 12, thereby driving the bracket 2 to descend. The limit rod 10 can prevent the bracket 2 from shaking when it descends, so that the bracket 2 can descend smoothly, and can ensure that the grid 4 and the cloth cover 5 under the bracket 2 can be aligned with the treatment pool 1, and ensure that the grid 4 and the cloth cover 5 can enter the treatment pool 1. Start the second motor 13 to make its output shaft reverse, otherwise the bracket 2 can be raised.

[0043] like Figure 1 and Figure 5 As shown, a beating assembly for beating the grid 4 is provided on the top of the grid 4;

[0044] The beating assembly includes: a beating rod 14, a fixing rod 15, and a pulling assembly for driving the fixing rod 15 to move in a vertical direction;

[0045] There are multiple rackets 14 and two fixed rods 15 . The rackets 14 are fixedly mounted at the bottom of the fixed rods 15 , and the rackets 14 are in contact with the grid 4 .

[0046] If the weather is hot, the water in the sludge evaporates quickly, and the sludge around the cloth cover 5 embedded in the upper part of the sludge will harden. If the cloth cover 5 leaves the sludge, too much of the hardened sludge will be taken out, which will cause the cloth cover 5 located below the grid 4 to harden and become unable to move, so that when the winding roller 7 winds up the cloth cover 5, it is easy to pull the cloth cover 5 apart.

[0047] When the bracket 2 rises, the output shaft of the first motor 8 is locked, so the winding roller 7 cannot rotate at this time, so that the cloth cover 5 is in a tensioned state, so that the cloth cover 5 will not be stretched by the silt;

[0048] Therefore, when the bracket 2 rises, the fixing rod 15 is driven by the pulling assembly to bring the slap rod 14 up and down quickly, so that the slap rod 14 hits the top of the grid 4, thereby generating vibration. Through multiple slaps of the slap rod 14, continuous vibration is generated, so that the transmission is transmitted to the cloth cover 5. The cloth cover 5 vibrates to shake off the hardened silt at the bottom, so that the cloth cover 5 can move normally, thereby avoiding the situation where too much hardened silt is located on the cloth cover 5, causing the cloth cover 5 to be unable to move and be torn off by the winding roller 7.

[0049] like Figure 5 As shown, the pulling assembly includes: a ring plate 16, a top plate 17, a spring 18, and an electromagnet 19;

[0050] The ring plate 16 is slidably sleeved on the outside of the connecting rod 3, the top plate 17 is fixedly sleeved on the outside of the connecting rod 3 and is located above the ring plate 16, the spring 18 is sleeved on the outside of the connecting rod 3 and is located between the top plate 17 and the ring plate 16, the two ends of the spring 18 are respectively fixedly connected to the top plate 17 and the ring plate 16, the electromagnet 19 is fixedly installed at the bottom of the top plate 17, the ring plate 16 is made of iron, and the fixing rod 15 is fixedly installed at the bottom of the ring plate 16.

[0051] The electromagnet 19 is energized to make it magnetic, so that the attraction ring plate 16 moves up with the fixed rod 15 and the racket 14, and the compression spring 18 deforms it to generate a force. Then the electromagnet 19 is powered off and the electromagnet 19 loses its magnetism. At this time, the compressed spring 18 releases its force to move the ring plate 16, the fixed rod 15 and the racket 14 down rapidly, and the racket 14 hits the grid frame 4 to make it vibrate. By continuously energizing and deenergizing the electromagnet 19, the racket 14 can continuously hit the grid frame 4.

[0052] like Figure 6 As shown, the paving assembly includes: a vertical plate 20, a connecting block 21, a threaded rod 22, and a third motor 23;

[0053] A groove is provided on the inner wall of one side of the treatment pool 1, and the vertical plate 20 is arranged in the groove. The inner side of the vertical plate 20 is flush with the inner side of the treatment pool 1. There is a gap between the bottom of the vertical plate 20 and the bottom wall of the treatment pool 1, and the gap height is 20CM. Two connecting blocks 21 are set and symmetrically fixedly installed on the outside of the vertical plate 20. Long grooves are symmetrically opened on the top of the treatment pool 1. The threaded rod 22 is rotatably installed in the long groove. The connecting block 21 is threadedly sleeved on the outside of the threaded rod 22. The number of the third motor 23 corresponds to that of the threaded rod 22. The third motor 23 is fixedly installed on the outside of the treatment pool 1, and one end of the output shaft of the third motor 23 is fixedly connected to one end of the corresponding threaded rod 22.

[0054] The third motor 23 is started to rotate its output shaft with the threaded rod 22, thereby driving the connecting block 21 to move with the vertical plate 20, and the sludge is leveled through the gap between the vertical plate 20 and the bottom wall of the treatment tank 1.

[0055] like Figure 6 As shown, an opening is provided on one side of the treatment tank 1 away from the vertical plate 20, and a closing plate 24 is provided in the opening. The closing plate 24 is fixedly connected to the treatment tank 1 by bolts.

[0056] The bolt is turned to remove it, and the closing plate 24 can be taken away at this time, and the opening is opened, so that the sludge inside can be taken out.

[0057] like Figure 1 As shown, the fabric cover 5 is made of nonwoven fabric.

[0058] The cloth cover 5 has good air permeability, which prevents the air in the treatment pool 1 from being unable to exchange with the outside world and breeding harmful gases.

[0059] Working principle: When in use, pour the sludge into the treatment pool 1, and level the sludge through the leveling component to make the thickness of the sludge 20CM, start the second motor 13 to make its output shaft rotate forward with the screw rod 12, thereby driving the bracket 2 to descend, so that the connecting rod 3, the grid 4, and the cloth cover 5 are lowered, so that the cloth cover 5 located under the grid 4 is embedded in the sludge for 2CM, and then the second motor 13 is turned off to stop the bracket 2 from descending, and the activated carbon 6 in the cloth cover 5 absorbs the odor emitted by the sludge to deodorize and purify the sludge. After a period of time, start the second motor 13 to reverse its output shaft, otherwise the bracket 2 can be raised, so that the connecting rod 3, the grid 4, and the cloth cover 5 are raised, so that the cloth cover 5 leaves the sludge. After the bracket 2 stops moving, the first motor 8 on one side is started to make its output shaft rotate with the connected winding roller 7, so as to reel up the cloth cover 5, and at the same time, the first motor 8 on the other side is started to make its output shaft rotate with the connected winding roller 7, so as to release the cloth cover 5, and the cloth cover 5 moves with the activated carbon 6, and the used activated carbon 6 above the treatment pool 1 is switched to the unused activated carbon 6, and then the bracket 2 is driven down again, and the cloth cover 5 with the unused activated carbon 6 is embedded in the sludge to continue deodorization, and the above operation is repeated at a certain interval, so that the activated carbon 6 on the sludge can be continuously replaced, so as to avoid the activated carbon 6 being saturated and not replaced, which affects the treatment effect of the sludge;

[0060] If the weather is hot, the water in the sludge evaporates quickly, and the sludge around the cloth cover 5 embedded in the upper part of the sludge will harden. If the cloth cover 5 leaves the sludge, too much of the hardened sludge will be taken out, which will cause the cloth cover 5 located below the grid 4 to harden and become unable to move, so that when the winding roller 7 winds up the cloth cover 5, it is easy to pull the cloth cover 5 apart.

[0061] Therefore, when the bracket 2 rises, the electromagnet 19 is energized to make it magnetic, so that the attraction ring plate 16 rises with the fixed rod 15 and the racket 14, and the compression spring 18 deforms it to generate a force, and then the electromagnet 19 is de-energized and the electromagnet 19 loses its magnetism. At this time, the compressed spring 18 releases its force to rapidly descend with the ring plate 16, the fixed rod 15, and the racket 14, and the racket 14 hits the grid 4 to make it vibrate. By continuously energizing and de-energizing the electromagnet 19, the racket 14 can continuously hit the grid 4. Through multiple hits of the racket 14, continuous vibration is generated, so that the transmission is transmitted to the cloth cover 5. The cloth cover 5 vibrates to shake off the hardened silt at the bottom, so that the cloth cover 5 can move normally, thereby avoiding the situation where too much hardened silt is located on the cloth cover 5, resulting in the cloth cover 5 being unable to move and being torn off by the winding roller 7.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
