Description

Technical Field

[0001] The present invention belongs to the technical field of waste collaborative treatment, and in particular relates to a solid waste cement kiln collaborative treatment device. Background Art

[0002] According to investigations, in actual production, the raw materials and fuels used to burn cement contain a certain amount of heavy metals. At the same time, many industrial wastes disposed of and utilized by cement plants around the world over the years contain heavy metals. This shows that cement kilns are not incapable of processing wastes containing heavy metals. As long as the heavy metal content is limited within a certain range, the environmental safety of cement products is guaranteed. However, this requires controlling the raw material ratio. In the current collaborative processing device, it is impossible to accurately control the raw material ratio and the waste processing volume, making the production process more difficult.

[0003] In order to solve the above problems, the existing technology generally uses a separate weighing machine before the waste materials are co-mixed. The weighing machine is used to install a placement box on the weighing machine. The waste materials and raw materials are placed in the placement box. The weighing machine can accurately weigh the weight of the added materials to ensure that the content of heavy metals in the product obtained after the co-processing of the materials is within a safe range. At the same time, a hydraulic cylinder is installed on the weighing machine. The telescopic characteristics of the hydraulic cylinder are used to control the dumping of the placement box, so that the materials can be quickly discharged after weighing, which is convenient for subsequent mixing and processing. However, there are still the following deficiencies in actual use:

[0004] ① From a practical point of view, cement waste is often mixed with a large amount of dust. Therefore, after the waste is dumped into the placement box once, a large amount of dust is likely to remain on the inner wall of the placement box. After long-term use, the dust is likely to stubbornly adhere to the inner wall of the placement box when it encounters water vapor. This is not only inconvenient for later cleaning, but also causes the weight of the placement box itself to increase, affecting the accuracy of the second weighing of the waste when it is fed into the placement box.

[0005] ② After the above-mentioned waste materials are mixed, the hydraulic cylinder pushes the placement box to dump the materials. Although it is convenient, the dust in the dumping process is easy to adhere to the piston rod of the hydraulic cylinder. The reciprocating use of a large amount of dust can easily cause wear or scratches on the surface of the piston rod. Once the surface of the piston rod is worn or scratched, the hydraulic cylinder cannot be used any longer, affecting the operation effect.

[0006] Therefore, a solid waste cement kiln co-disposal device is needed to solve the problem in the prior art that when the co-disposal device is in use, a large amount of dust is likely to remain on the inner wall of the placement box after the material is dumped once, which is likely to increase the weight of the placement box itself, and the dust during the dumping process is likely to adhere to the piston rod of the hydraulic cylinder, and the reciprocating use of a large amount of dust is likely to cause wear or scratches on the surface of the piston rod.

[0033] See also Figure 1-8 The present invention provides a solid waste cement kiln co-processing device, comprising a mixing bin 1, a feeding port 3 provided on the side of the top of the mixing bin 1, and a mixing motor 2 installed at the center of the top of the mixing bin 1. An agitator fixed to the output shaft of the mixing motor 2 is rotatably provided in the inner cavity of the mixing bin 1. The top of the cylinder wall of the mixing bin 1 is vertically fixed to a supporting platform 4 adjacent to the feeding port 3. A weighing device 5 is installed on the supporting platform 4, and a material receiving mechanism is provided on the weighing device 5.

[0034] The material receiving mechanism includes a carrying plate 7 fixed to the top of the weighing device 5, a placement box 6 horizontally arranged above the carrying plate 7, a scraping component arranged inside the placement box 6, and a dumping component arranged on the carrying plate 7. The end surface of the placement box 6 facing the mixing motor 2 is open.

[0035] By setting up the placement box 6 and the weighing device 5, the weight of the raw material and the waste can be quickly weighed to ensure that the added weight between the two materials is equal to the expected added weight, thereby conveniently ensuring that the heavy metal content in the product obtained after the coordinated processing is within a safe range.

[0036] The dumping component includes a support plate 8 vertically hinged to one side of the bottom surface of the placement box 6, a push plate 11 obliquely hinged to the other side of the bottom surface of the placement box 6, a guide groove 9 horizontally opened on the top surface of the carrier plate 7, and a movable block 10 slidably arranged inside the guide groove 9. The end of the support plate 8 is vertically fixed to the carrier plate 7, and the end of the push plate 11 is hingedly connected to the movable block 10. A hydraulic cylinder 12 is installed on the side of the carrier plate 7 away from the mixing motor 2. The telescopic end of the hydraulic cylinder 12 penetrates the inner side of the guide groove 9 and is fixed to the movable block 10.

[0037] Through the arrangement of the support plate 8, the hydraulic cylinder 12, the movable block 10 and the push plate 11, the hydraulic cylinder 12 is opened, and the telescopic shaft of the hydraulic cylinder 12 drives the movable block 10 to slide away from the mixing motor 2 on the inner side of the guide groove 9, and then the push plate 11 pushes on one side of the placement box 6, so that the placement box 6 gradually tilts, and the material is poured from the feeding port 3 into the inner cavity of the mixing bin 1.

[0038] The scraping component includes a scraper 13 slidably arranged on the inner side of the placement box 6, a fixed plate 14 fixed to the top of the scraper 13, a slide 15 fixed horizontally in an L shape on the side of the placement box 6, and a sliding sleeve 16 slidably arranged on the slide 15. A concave supply block 27 is fixed on the sliding sleeve 16, and the end of the fixed plate 14 is inserted into the inner side of the supply block 27. An adjustment groove 28 is provided on the innermost inner wall of the supply block 27. A self-locking component for locking the fixed plate 14 is provided in the adjustment groove 28. A transmission component for driving the sliding sleeve 16 to slide during the tipping of the placement box 6 is provided on the end surface of the placement box 6 away from the mixing motor 2.

[0039] Through the setting of the scraping component, during the tilting process of the placement box 6, the sliding sleeve 16 can be acted upon by the transmission component, and the force is applied to slide along the slide bar 15 on the side of the placement box 6, so that the fixed plate 14 and the scraper 13 gradually slide toward the opening of the placement box 6, thereby the scraper 13 can implement the boosting effect of the material, accelerate the feeding rate of the material to the inner side of the feeding port 3, and can also implement the scraping of the inner wall of the placement box 6 to remove the powder attached to the inner wall of the placement box 6 during the process of receiving the material, so as to prevent a large amount of powder from being attached and getting damp, and stubbornly adhering to the inner wall of the placement box 6, resulting in an increase in the self-weight of the placement box 6, thereby affecting the measurement accuracy of the weighing device 5 during the secondary material addition.

[0040] Further as Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, it is worth mentioning that the transmission assembly includes a transmission rod 17 horizontally arranged on the outer wall of the placement box 6, a rotating cylinder 19 sleeved on the end of the transmission rod 17, a first gear 20 fixed to one end of the rotating cylinder 19, and a fixed ring 18 rotatably arranged on the other end of the rotating cylinder 19. The fixed ring 18 is tightly sleeved on the rod body of the transmission rod 17, and the first gear 20 is meshed with the second gear 21. The central axis of the second gear 21 is rotatably connected to a fixed seat 22 vertically fixed to the outer wall of the placement box 6. A tooth plate 23 meshing with the second gear 21 is fixedly embedded on the sliding sleeve 16, and the rod body of the transmission rod 17 is rotatably sleeved with a bearing seat fixed to the outer wall of the placement box 6.

[0041] A hand-winding roller 24 is tightly sleeved on the body of the rotating drum 19, and a rope 25 is wound around the roller body of the hand-winding roller 24. The end of the rope 25 is fixed to the top surface of the supporting plate 7. The transmission rod 17 is located in the inner cavity of the rotating drum 19 and is provided with a first torsion spring 26. One end of the first torsion spring 26 is fixedly connected to the inner wall of the rotating drum 19, and the other end of the first torsion spring 26 is fixedly connected to the rod body of the transmission rod 17.

[0042] By setting the hand-rolled roller 24 and the rope 25, the carrying plate 7 can remain fixed during the tilting of the storage box 6, gradually stretching the rope 25, and the hand-rolled roller 24 can drive the rotating drum 19 and the first gear 20 to rotate due to the friction force;

[0043] Through the arrangement of the rotating drum 19, the first gear 20, the second gear 21 and the toothed plate 23, during the rotation of the rotating drum 19, the first gear 20 is meshed with the second gear 21, and the second gear 21 is simultaneously meshed with the toothed plate 23, and then the sliding sleeve 16 is forced to slide along the slide bar 15 on the side of the storage box 6, so that the fixed plate 14 and the scraper 13 gradually slide toward the opening of the storage box 6;

[0044] By setting the first torsion spring 26 and utilizing the elastic force of the first torsion spring 26, after completing the dumping of the material once, the hydraulic cylinder 12 is driven in the reverse direction so that when the placement box 6 is reset and rotated, the rotating drum 19 can, under the elastic force of the first torsion spring 26, make the hand-winding roller 24 reversely rewind the wire rope 25 and reversely rotate the first gear 20, so that the sliding sleeve 16 drives the fixed plate 14 and the scraper 13 in the reverse direction on the side wall of the placement box 6 to reset, thereby facilitating the secondary scraping of the material.

[0045] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that a winding frame 34 is fixed on one side of the top surface of the supporting plate 7 adjacent to the hydraulic cylinder 12, a dustproof cloth 37 is horizontally arranged on the opening of the guide groove 9, and a winding assembly for winding the dustproof cloth 37 is arranged on the inner side of the winding frame 34.

[0046] The winding assembly includes a support rod 35 fixed between the inner walls on both sides of the winding frame 34 and a winding drum 36 mounted on the rod body of the support rod 35. One end of the dustproof cloth 37 is fixed to the movable block 10, and the other end of the dustproof cloth 37 is inserted into the inner side of the winding frame 34 and wound around the rod body of the winding drum 36. A second torsion spring 38 is also provided on the rod body of the support rod 35. One end of the second torsion spring 38 is fixed to the rod body of the support rod 35, and the other end of the second torsion spring 38 is fixed to the inner wall of the winding drum 36.

[0047] Through the arrangement of the winding frame 34 and the winding assembly, when the hydraulic cylinder 12 drives the movable block 10 to slide back and forth on the inner side of the guide groove 9, the movable block 10 can repeatedly pull the dustproof cloth 37. Under the action of the winding assembly, the dustproof cloth 37 can cover the opening of the guide groove 9 above the telescopic shaft of the hydraulic cylinder 12 in real time. Thus, the dustproof cloth 37 and the movable block 10 cooperate with each other to effectively protect the telescopic shaft and telescopic end of the hydraulic cylinder 12, reduce the adhesion of dust and impurities on the telescopic shaft of the hydraulic cylinder 12, reduce the wear of the telescopic shaft of the hydraulic cylinder 12, and improve the service life of the hydraulic cylinder 12.

[0048] This solution has the following working process: when in use, waste materials and raw materials can be added to the placement box 6 respectively, and the increase in the weight data on the weighing device 5 can be recorded respectively during the addition to ensure that the added weight of the two materials is equal to the expected added weight. After the addition of the materials is completed, the hydraulic cylinder 12 can be opened, and the telescopic shaft of the hydraulic cylinder 12 drives the movable block 10 to slide away from the mixing motor 2 in the inner side of the guide groove 9. Then, the movable block 10 can be pushed up by the push plate 11 on one side of the placement box 6, so that the placement box 6 gradually tilts, and the materials are poured from the feeding port 3 into the inner cavity of the mixing bin 1, so that the materials are stirred and mixed by the agitator;

[0049] During the process of tilting the placement box 6, the carrying plate 7 can remain in a fixed state, gradually stretching the rope 25, and the hand-rolled roller 24 can be driven by the friction force to drive the rotating drum 19 and the first gear 20 to rotate, so that the first gear 20 is meshed with the second gear 21, and the second gear 21 is synchronously meshed with the toothed plate 23, and then the sliding sleeve 16 is forced to slide along the slide bar 15 on the side of the placement box 6, so that the fixed plate 14 and the scraper 13 gradually slide toward the opening of the placement box 6, thereby the scraper 13 can implement the material boosting effect, speed up the material delivery rate to the inside of the feeding port 3, and can also implement the scraping of the inner wall of the placement box 6 to remove the powder attached to the inner wall of the placement box 6 during the process of receiving the material;

[0050] During the tilting process of the placement box 6, when the hand-winding roller 24 drives the rotating drum 19 to rotate, the rotating drum 19 can twist the first torsion spring 26 synchronously with the rod body of the transmission rod 17, so that the first torsion spring 26 is deformed, and then the elastic force of the first torsion spring 26 is used to reversely drive the hydraulic cylinder 12 after completing the dumping of the material once, so that when the placement box 6 is reset and rotated, the rotating drum 19 can reversely reel the wire rope 25 under the elastic force of the first torsion spring 26, and reversely rotate the first gear 20, so that the second gear 21 rotates in the opposite direction and meshes with the tooth plate 23, and then the sliding sleeve 16 reversely drives the fixed plate 14 and the scraper 13 on the side wall of the placement box 6 to reset, so as to facilitate secondary scraping;

[0051] In addition, when the hydraulic cylinder 12 is extended and retracted, the movable block 10 slides back and forth inside the guide groove 9, and the movable block 10 can repeatedly pull the dustproof cloth 37. When the movable block 10 moves away from the hydraulic cylinder 12, the movable block 10 pulls the dustproof cloth 37, causing the winding drum 36 to rotate on the rod body of the support rod 35 under the action of friction, and causing the winding drum 36 to twist the second torsion spring 38 during the movement. Then, when the movable block 10 moves closer to the hydraulic cylinder 12, the movable block 10 gradually releases the pull on the dustproof cloth 37, and the winding drum 36 can rotate in the opposite direction to rewind the dustproof cloth 37 under the action of the reset torsion of the second torsion spring 38. Therefore, during this process, the dustproof cloth 37 can cooperate with the movable block 10 to cover the opening of the guide groove 9 above the telescopic axis of the hydraulic cylinder 12 in real time, thereby effectively protecting the telescopic axis and telescopic end of the hydraulic cylinder 12.

[0052] According to the above working process, it can be known that: through the setting of the placement box 6 and the weighing device 5, the weight of the raw material and the waste can be weighed quickly to ensure that the content of heavy metals in the product obtained after the coordinated treatment is within a safe range. Through the setting of the support plate 8, the hydraulic cylinder 12, the movable block 10 and the push plate 11, the measured material can be easily poured from the feeding port 3 into the inner cavity of the mixing bin 1. Through the setting of the hand-rolled roller 24 and the rope 25, during the tilting process of the placement box 6, the rope 25 is stretched, and the hand-rolled roller 24 can be driven by the friction force to drive the rotating drum 19 and the first gear 20 to rotate. Through the setting of the rotating drum 19, the first gear 20, the second gear 21 and the tooth plate 23, during the rotation of the rotating drum 19, the first gear 20 is meshed with the second gear 21, and the second gear 21 is meshed with the tooth plate 23 synchronously, and then the sliding sleeve 16 is forced to move along the slide bar 15 on the side of the placement box 6. The first torsion spring 26 is used to adjust the hydraulic cylinder 12 so that the lifting and lowering of the hydraulic cylinder 12 are stopped, and the hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position. The hydraulic cylinder 12 is driven to rotate and return to the original position.

[0053] Further as Figure 7 and Figure 8As shown, it is worth mentioning that the self-locking assembly includes a locking block 29 slidably arranged in the open part of the adjustment groove 28 and a push-pull plate 30 vertically arranged on the inner side of the adjustment groove 28. A positioning hole for the locking block 29 is opened at the end of the supporting platform 4. One end of the locking block 29 is inserted into the positioning hole, and a buffer member is provided between the other end of the locking block 29 and the push-pull plate 30. A screw 33 rotatably connected to the push-pull plate 30 is threadedly penetrated on the side of the solid block 27 away from the fixed plate 14, and the locking block 29 is inclined downward on the side facing the fixed plate 14.

[0054] The buffering component includes two guide telescopic rods 31 symmetrically fixed between the locking block 29 and the push-pull plate 30, and a buffer spring 32 is arranged between the two guide telescopic rods 31, one end of the buffer spring 32 is fixed to the locking block 29, and the other end of the buffer spring 32 is fixed to the push-pull plate 30.

[0055] By means of the arrangement of the screw 33, the push-pull plate 30 and the locking block 29, if the scraper 13 is severely worn after a certain period of time, the scraper 13 is twisted, so that the push-pull plate 30 is forced to slide away from the fixed plate 14 inside the adjustment groove 28. During this process, the push-pull plate 30 will simultaneously act on the locking block 29, so that the locking block 29 is removed from the positioning hole, thereby releasing the fixing effect on the fixed plate 14, and facilitating the removal and replacement of the fixed plate 14 and the scraper 13.

[0056] On the contrary, when installing the scraper 13, it is only necessary to clamp the end of the fixing plate 14 to the inner side of the supply block 27. Then, during the placement of the end of the fixing plate 14, the fixing plate 14 can conflict with the slope of the locking block 29. The locking block 29 is squeezed to the inside of the adjustment groove 28 and compresses the buffer spring 32, so as not to hinder the insertion process of the fixing plate 14. When the fixing plate 14 is completely inserted into the inner side of the supply block 27, that is, the positioning hole and the adjustment groove 28 are in the same horizontal position, the locking block 29 can reset itself and insert into the positioning hole under the action of the rebound force of the buffer spring 32, automatically locking the fixing plate 14, and facilitating the installation of the scraper 13.

[0057] In summary: by setting the placement box 6 and the weighing device 5, the weight of the raw material and the waste can be weighed quickly to ensure that the content of heavy metals in the product obtained after the collaborative treatment is within a safe range. By setting the support plate 8, the hydraulic cylinder 12, the movable block 10 and the push plate 11, the measured material can be easily poured from the feeding port 3 into the inner cavity of the mixing bin 1. By setting the hand roller 24 and the rope 25, during the tilting process of the placement box 6, the rope 25 is stretched, and the hand roller 24 can be driven by the friction force to drive the rotating drum 19 and the first gear 20 to rotate. And the setting of the tooth plate 23, during the rotation of the drum 19, the first gear 20 is meshed with the second gear 21, and the second gear 21 is meshed with the tooth plate 23 synchronously, and then the sliding sleeve 16 is forced to slide along the slide bar 15 on the side of the placement box 6, so that the fixed plate 14 and the scraper 13 gradually slide toward the opening of the placement box 6. Through the setting of the first torsion spring 26, the elastic force of the first torsion spring 26 is utilized. After completing the dumping of a material, the hydraulic cylinder 12 is driven in the reverse direction, so that when the placement box 6 is reset and rotated, the drum 19 can, under the action of the elastic force of the first torsion spring 26, make the hand winding roller 24 reversely reel in the rope 25 and reversely supply the material. Turn the first gear 20, so that the sliding sleeve 16 drives the fixed plate 14 and the scraper 13 to reset in the opposite direction on the side wall of the placement box 6, which is convenient for secondary scraping. Through the arrangement of the winding frame 34 and the winding assembly, when the hydraulic cylinder 12 drives the movable block 10 to slide back and forth inside the guide groove 9, the telescopic shaft and telescopic end of the hydraulic cylinder 12 are effectively protected, reducing the adhesion of dust and impurities on the telescopic shaft of the hydraulic cylinder 12, reducing the wear of the telescopic shaft of the hydraulic cylinder 12, and improving the service life of the hydraulic cylinder 12. Through the arrangement of the screw 33, the push-pull plate 30 and the locking block 29, if the scraper 13 is severely worn after a certain period of time, , twist the scraper 13 so that the locking block 29 is removed from the positioning hole, releasing the fixing effect on the fixing plate 14, making it convenient to replace the fixing plate 14 and the scraper 13. On the contrary, when installing the scraper 13, the end of the fixing plate 14 is stuck to the inner side of the supply block 27, and the fixing plate 14 can conflict with the slope of the locking block 29. The locking block 29 is squeezed to retract toward the inside of the adjusting groove 28 and compresses the buffer spring 32. When the fixing plate 14 is completely stuck in the inner side of the supply block 27, the locking block 29 can be reset by itself under the action of the rebound force of the buffer spring 32 to insert into the positioning hole, automatically locking the fixing plate 14, and facilitating the installation of the scraper 13.
