Description

The left part of the output shaft of the motor 14 is fixedly connected with a rotating member 17, which is rotatably connected to the feed pipe 12, and further includes a rotating member 110, which is rotatably connected to the lower hopper 13, and a transmission assembly is arranged on the rotating member 110, which is used to drive the rotating member 110 to rotate, and a storage frame 111 is fixedly connected to the left part of the lower hopper 13, and the inner bottom of the storage frame 111 is set as an inclined surface with a left high and a right low, and a filter 112 is slidably connected in the storage frame 111, and the filter 112 extends The filter 112 is pressed and matched with the rotating member 110. Reset springs 117 are connected between the front and rear sides of the filter 112 and the storage frame 111. The upper part of the storage frame 111 is slidably connected with a cover 113. The front part of the storage frame 111 is slidably connected with a limiting rod 116. The limiting rod 116 is plug-fitted with the cover 113. A collision assembly is provided on the cover 113, which is used to knock off the sludge attached to the impurities.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, the transmission assembly includes two transmission wheels 18 , one of which is fixedly connected to the right part of the rotating member 110 , and the other is fixedly connected to the output shaft of the driving motor 14 . A transmission belt 19 is wound between the two transmission wheels 18 .

[0039] like Figure 6 As shown, the collision assembly includes a sliding frame 114 , the sliding frame 114 is slidably connected to the cover 113 , and a compression spring 115 is connected between the sliding frame 114 and the cover 113 .

[0040] The device is used to treat sludge and oily sludge. Taking sludge as an example, the device can dry and dehydrate the sludge, and can directly incinerate and mineralize the dehydrated sludge. When in use, the device is started to rotate the outer kettle 11, the middle kettle 15 and the inner kettle 16, and the driving motor 14 is started at the same time. The output shaft of the driving motor 14 drives the rotating member 17 to rotate, and the sludge is put into the lower hopper 13. Driven by the output shaft of the driving motor 14, the adjacent transmission wheel 18 rotates, and driven by the transmission belt 19, the other transmission wheel 18 also rotates, and the rotating member 110 rotates with the transmission wheel 18. The rotating member 110 squeezes the filter 112 during the rotation. Under the squeezing of the rotating member 110, the filter 112 moves upward, and the reset spring 11 7 compression, when the rotating member 110 rotates to release the filter element 112, under the action of the reset spring 117, the filter element 112 moves downward to reset, and as the rotating member 110 continues to rotate, this process is repeated, so that the filter element 112 shakes up and down, so that the sludge put into the lower hopper 13 can be filtered by the shaking of the filter element 112, so that the sludge can pass through the filter element 112 and fall into the feed pipe 12, and the impurities in the sludge will be blocked by the filter element 112, and the impurities will enter the storage frame 111 along the filter element 112. At the same time, because the surface of the impurities entering the storage frame 111 may still be attached to some sludge, these impurities will move upward together with the filter element 112 moving upward. When the filter element 112 When the impurities are driven to move upward until they come into contact with the sliding frame 114, the impurities will hit the sliding frame 114, causing the sliding frame 114 to move upward, compressing the extrusion spring 115, and the impact force generated by the impact can wash away the sludge on the surface of the impurities. At this time, the washed away sludge can pass through the filter element 112 and fall to the inner bottom of the storage frame 111, and because the inclined surface of the inner bottom of the storage frame 111 can guide the sludge to fall into the feed pipe 12, the sludge entering the feed pipe 12 will enter the inner kettle 16 under the push of the rotating member 17, and under the guidance of the guide plate on the inner wall of the inner kettle 16, the sludge and the energy ball can move to the left, and then the sludge and the energy ball will fall into the middle kettle 15, and then under the guidance of the guide plate on the inner wall of the middle kettle 15, the sludge and the energy ball move to the right. When the sludge and When the energy ball moves to the rightmost end of the middle kettle 15, the energy ball will re-enter the inner kettle 16 through the circulation component 104, so that the energy ball can continue to mix and circulate with the sludge, and the sludge will fall into the outer kettle 11 through the sieve plate 103. The energy ball can play the function of absorbing heat and transferring heat in the process of circulation, and can also help disperse the sludge. At the same time, the energy ball will continue to roll and collide during operation, and can remove the coke friction attached to the inner walls of the middle kettle 15 and the inner kettle 16. It can be seen that the provision of energy balls can improve production efficiency. Then, as the outer kettle 11 rotates, the sludge will move to the left under the guidance of the guide plate on the inner wall of the outer kettle 11, and gradually approach the incinerator 101. At this time, the three-pass drying of the sludge is completed, and the outlet pipe on the head cover 102 is opened.The moisture generated by the sludge drying is discharged through the air outlet pipe on the head cover 102 at this time, and then the air outlet pipe on the head cover 102 is closed. After the sludge enters the incinerator 101, it is incinerated in the incinerator 101. Because the sludge still has residual heat after the three-pass drying, it can be quickly burned after entering the incinerator 101. At the same time, the high-temperature flue gas generated by the combustion can also participate in the three-pass drying, and can dry and dehydrate the sludge, so it is not only energy-saving but also highly efficient. After the sludge is processed, the air outlet pipe on the head cover 102 is opened and the flue gas is discharged, and then the air outlet pipe on the head cover 102 is closed, and the device is closed to remove the incinerated The product is taken out from the incinerator 101, and then the limiting rod 116 is manually moved forward so that the limiting rod 116 pulls out the cover 113, and then the cover 113 is moved upward together with the sliding frame 114, and then the impurities in the storage frame 111 are cleaned, and then the cover 113 is covered back on the storage frame 111, and the limiting rod 116 is moved backward to reset so that the limiting rod 116 limits the cover 113 again, and the filter element 112 is rotated and squeezed by the rotating member 110, so that the filter element 112 shakes up and down, so that the filter element 112 can filter out the impurities in the sludge, and the impurities can be prevented from clogging the device.

[0041] Embodiment 2: Based on embodiment 1, Figure 8 , Fig. 9 and Fig.10 As shown, the three-pass drying sludge and oil sludge treatment device also includes a cleaning mechanism, which is arranged on the feed pipe 12. The cleaning mechanism includes a gas storage tank 21, which is fixedly connected to the feed pipe 12. A reciprocating screw rod 28 is rotatably connected to the gas storage tank 21, and a piston 29 is threadedly connected to the reciprocating screw rod 28. The piston 29 is slidably connected to the gas storage tank 21. A trigger component is arranged on the outer kettle 11, and the trigger component is used to drive the piston 29 to move. A rotating frame 26 is fixedly connected to the right part of the middle kettle 15, and the rotating frame 26 is connected to the gas storage tank 21. Rotating connection, a sealing ring is provided at the connection between the rotating frame 26 and the gas tank 21, the rotating frame 26 is connected to the gas tank 21, the left part of the outer kettle 11 is fixedly connected with three circumferentially distributed fixed blocks 25, the left part of the middle kettle 15 is also fixedly connected with three circumferentially distributed fixed blocks 25, the fixed blocks 25 are all fixedly connected with airbags 2, the airbags 2 are all connected to the rotating frame 26, the airbags 2 are made of wear-resistant and cutting-resistant materials, which can avoid damage to the airbags 2 and extend the service life of the airbags 2, and the airbags 2 are all fixedly connected with multiple circumferentially distributed spikes 27.

[0042] like Figure 8 , Fig. 9 and Fig.10 As shown, the trigger assembly includes a connecting rod 22, which is fixed to the right part of the outer kettle 11. The right part of the connecting rod 22 is fixed to a first gear 23, and the right part of the reciprocating screw 28 is fixed to a second gear 24, which meshes with the first gear 23.

[0043] In order to prevent the sludge from agglomerating during the three-pass drying process, when the outer kettle 11 and the middle kettle 15 rotate, the connecting rod 22, the air bag 2 and the rotating frame 26 also rotate accordingly. Driven by the connecting rod 22, the first gear 23 also rotates accordingly. Because the gas storage tank 21, the piston 29 and the second gear 24 will not rotate with the outer kettle 11 and the middle kettle 15, at this time, driven by the first gear 23, the second gear 24 rotates with its own center as the rotation center, and the reciprocating screw 28 rotates accordingly. Driven by the reciprocating screw 28, the piston 29 reciprocates left and right. When the piston 29 moves to the left, the piston 29 squeezes the gas in the gas storage tank 21 into the rotating frame 26, and the gas passes through the rotating frame 26. The rotating frame 26 is injected into the airbag 2, so that the airbag 2 is expanded. The spikes 27 on the airbag 2 stand up at this time, so that when the outer pot 11, the middle pot 15 and the inner pot 16 rotate, the spikes 27 on the airbag 2 can break up the agglomerated sludge. When the piston 29 moves to the right, the gas storage tank 21 is in a negative pressure state. The gas in the airbag 2 will flow back to the gas storage tank 21 through the rotating frame 26. The airbag 2 is deflated at this time. As the reciprocating screw 28 continues to rotate, the above process is repeated continuously, and the airbag 2 is inflated to expand, so that the spikes 27 on the airbag 2 stand up, so that the agglomerated sludge can be broken up by the spikes 27, thereby preventing the agglomerated sludge from clogging the device, which is beneficial to three-pass drying.

[0044] like Fig.11 and Fig.12 As shown, the three-pass drying sludge and oil sludge treatment device also includes a scraping mechanism, which is arranged on the filter element 112. The scraping mechanism includes a fixed rod 44, which is fixedly connected to the upper right part of the filter element 112. A breaking frame 45 is slidably connected to the fixed rod 44. A moving component is arranged on the rotating member 110, and the moving component is used to drive the breaking frame 45 to move.

[0045] like Fig.11 and Fig.12 As shown, the moving assembly includes a fixed frame 42, which is fixedly connected to the right part of the lower hopper 13, and the right part of the fixed frame 42 is slidably connected to the guide rod 41. The right part of the rotating member 110 is fixedly connected to the connecting disc 4, and the connecting disc 4 is slidably connected to the guide rod 41. The upper part of the guide rod 41 is slidably connected to the support rod 43, and the support rod 43 extends into the lower hopper 13. The left part of the support rod 43 is fixedly connected to the debonding frame 45.

[0046] Because the sludge poured into the lower hopper 13 may clump, the sludge can be preliminarily broken up by the breaking frame 45. Therefore, when the rotating member 110 rotates, the connecting disc 4 also rotates under the drive of the rotating member 110. Driven by the connecting disc 4, the guide rod 41 reciprocates back and forth on the fixed frame 42. Under the squeezing of the guide rod 41, the support rod 43 and the breaking frame 45 also reciprocate back and forth. In this way, the breaking frame 45 can break up the sludge poured into the lower hopper 13. The reciprocating motion of the breaking frame 45 can break up the sludge poured into the lower hopper 13, thereby preventing the agglomerated sludge from clogging the filter element 112.

[0047] like Fig.13 and Fig.14 As shown, the three-pass drying sludge and oil sludge treatment device also includes a knocking mechanism, which is arranged on the outer kettle 11. The knocking mechanism includes a T-shaped frame 5. The number of the T-shaped frames 5 is two. The two T-shaped frames 5 are respectively fixed to the upper and lower sides of the outer kettle 11. The T-shaped frames 5 are slidably connected with a knocking frame 51. The knocking frame 51 and the adjacent T-shaped frames 5 are connected with a linear spring 52. The rear upper part of the support base 1 is fixed with an extrusion piece 54, and the right part of the knocking frame 51 is fixed with a connecting frame 53. The connecting frame 53 is extruded and matched with the extrusion piece 54.

[0048] During the three-pass drying process, the sludge may adhere to the inner walls of the outer kettle 11, the middle kettle 15 and the inner kettle 16. When the thickness of the sludge attached to the inner wall is thick, it may cause blockage, making it difficult for other sludge to flow. In order to solve this problem, when the outer kettle 11 rotates, the T-shaped frame 5, the knocking frame 51 and the linear spring 52 also rotate under the drive of the outer kettle 11. Under the drive of the knocking frame 51, the connecting frame 53 also rotates together. When the connecting frame 53 rotates to contact with the extrusion member 54, the connecting frame 53 is squeezed by the extrusion member 54. The frame 53 drives the knocking frame 51 to move upward, and the linear spring 52 is compressed. Then, as the connecting frame 53 continues to rotate, the extrusion piece 54 will gradually loosen the connecting frame 53. At this time, under the action of the linear spring 52, the connecting frame 53 and the knocking frame 51 move downward to reset. At this time, the knocking frame 51 will knock on the outer kettle 11, thereby causing the outer kettle 11 to vibrate. This vibration can be transmitted to the middle kettle 15 and the inner kettle 16, thereby shaking off the sludge attached to the inner walls of the outer kettle 11, the middle kettle 15 and the inner kettle 16, thereby avoiding blockage.

[0049] like Fig.15 As shown, the three-pass drying sludge and oil sludge treatment device also includes a rotating mechanism, which is arranged on the lower hopper 13. The rotating mechanism includes a fixed seat 6, which is fixedly connected to the upper right part of the lower hopper 13. A rotating plate 61 is rotatably connected to the fixed seat 6, and a return torsion spring 62 is wound between the front and rear sides of the rotating plate 61 and the fixed seat 6.

[0050] When the sludge is put into the lower hopper 13, if the sludge falls on a certain place on the left side of the filter element 112, the filtering efficiency of the filter element 112 will be affected. In order to avoid this situation, the sludge can be guided by the rotating plate 61. When the sludge is put into the lower hopper 13, the sludge can be poured on the rotating plate 61. At this time, the sludge will press down the rotating plate 61, so that the rotating plate 61 rotates and the reset torsion spring 62 twists. This can buffer the impact force of the sludge on the rotating plate 61 and extend the service life of the rotating plate 61. After the sludge falls on the rotating plate 61, the rotating plate 61 will guide the sludge. The sludge is guided to fall on the right side of the filter element 112. Because the filter element 112 itself has a certain inclination, the filter element 112 can guide the sludge to flow from right to left, so that the sludge can be evenly distributed on the filter element 112, so that the sludge can be better filtered. When the force of the sludge pressing down on the rotating plate 61 is weakened, under the action of the reset torsion spring 62, the rotating plate 61 will rotate in the opposite direction and reset. By guiding the sludge by the rotating plate 61, the position where the sludge falls on the filter element 112 can be controlled, thereby preventing the sludge from falling on a certain place on the left side of the filter element 112 and affecting the filtration.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
