Description

Technical Field

[0001] This application relates to the field of solid waste treatment, and in particular to a dust-proof ash-collecting hopper. Background Technology

[0002] During the waste tire processing, the waste tires are fed into a pyrolysis furnace for heating. After heating, the waste tires produce fuel oil and pyrolysis gas, which are then reused. The remaining carbon black and other materials continue to accumulate inside the pyrolysis furnace. After cooling, the carbon black is discharged from the slag outlet on one side of the pyrolysis furnace.

[0003] During the discharge process from the pyrolysis furnace, the ash discharger needs to collect the carbon black through an ash hopper. Currently used ash hoppers are generally open-topped, collecting the carbon black inside by connecting a negative pressure suction pipe to the bottom of the hopper. However, this type of ash hopper structure easily causes the carbon black to scatter upon contact with the ash hopper, impacting the surrounding environment. Utility Model Content

[0004] In order to reduce the impact of the dust collection hopper on the surrounding environment during the process of collecting carbon black, this application provides a dust-proof dust collection hopper.

[0005] The dust-proof and ash-collecting hopper provided in this application adopts the following technical solution:

[0006] A dust-proof hopper includes a dust-collecting hopper with a feed inlet on the upper side and a discharge pipe connected to the lower side of the dust-collecting hopper corresponding to the feed inlet. The dust-collecting hopper has an inner partition layer inside, which is parallel to and spaced apart from the inner wall of the dust-collecting hopper.

[0007] By adopting the above technical solution, when it is necessary to discharge carbon black from inside the pyrolysis furnace, the filter bag is connected to the discharge port of the pyrolysis furnace, and then the other end of the filter bag is inserted into the feed port of the ash hopper. The suction pipe is connected to the discharge pipe. Then, during the process of guiding the carbon black into the ash hopper, the carbon black first moves downward in the middle of the inner partition. Then, when the carbon black contacts the bottom of the ash hopper, it moves upward between the inner partition and the inner wall of the ash hopper. After contacting the top wall of the ash hopper, it moves downward again between the inner partitions. This reduces the phenomenon of carbon black moving out of the ash hopper and causing pollution to the surrounding environment.

[0008] Optionally, the upper side of the dust suction hopper is provided with a clamping assembly for clamping the cloth bag inserted into the feed inlet.

[0009] By adopting the above technical solution, after the filter bag is inserted into the feed inlet of the ash hopper, the filter bag at the feed inlet is clamped by the clamping component, so that the filter bag can stably guide carbon black into the ash hopper. This reduces the phenomenon that the connection between the filter bag and the ash hopper is unstable during the process of guiding carbon black into the ash hopper, which causes carbon black to scatter and affect the surrounding environment.

[0010] Optionally, the clamping assembly has two opposing clamping plates, which are arranged opposite each other and used to clamp the cloth bag.

[0011] By adopting the above technical solution, after inserting the cloth bag into the feed inlet of the dust suction hopper, the two clamping plates abut against the cloth bag, thereby realizing the clamping process of the cloth bag.

[0012] Optionally, clamping screws are fixedly connected to opposite sides of the two clamping plates, and a driven pulley is threaded onto the outside of each clamping screw.

[0013] By adopting the above technical solution, when it is necessary to move the clamping plate to hold the cloth bag, the driven pulley is rotated. During the rotation of the driven pulley, the clamping screw is moved, and during the movement of the clamping screw, the clamping plate is moved, so that the clamping plate abuts against the cloth bag and clamps the cloth bag.

[0014] Optionally, each driven pulley is provided with a drive pulley on one side, and each drive pulley and the adjacent driven pulley are fitted with the same connecting belt, and the two drive pulleys are fixedly connected to the same drive shaft.

[0015] By adopting the above technical solution, when it is necessary to move the clamping plate to hold the bag, the drive shaft is rotated. During the rotation of the drive shaft, the drive pulley connected to it is rotated. During the rotation of the drive pulley, the connecting belt is rotated. During the rotation of the connecting belt, the driven pulley connected to it is rotated. During the rotation of the driven pulley, the clamping screw and the clamping plate are moved, which facilitates the process of moving the clamping screw and the clamping plate by the staff.

[0016] Optionally, each of the clamping plates is provided with a pressure plate at the end near the other clamping plate, and each pressure plate is connected to the side wall of the adjacent clamping plate with a compression spring.

[0017] By adopting the above technical solution, before the clamping plate comes into contact with the cloth bag, the pressure plate on one side of the clamping plate first comes into contact with the clamping plate and the cloth bag. Then, during the movement of the clamping plate, the two clamping plates come into contact with each other and squeeze the compression spring, thereby achieving full clamping of the cloth bag and reducing the phenomenon that the position of the cloth bag is difficult to control before the clamping plate comes into contact with the cloth bag.

[0018] Optionally, multiple barbs are fixedly connected to the opposite sides of both clamps.

[0019] By adopting the above technical solution, when the clamping plate and the filter bag come into contact, the barbs connected to one side of the clamping plate abut against the filter bag. By setting the barbs to abut against the filter bag, the phenomenon that the filter bag shakes when guiding carbon black into the dust collection hopper, causing the carbon black inside the filter bag to scatter and affect the surrounding environment, is reduced.

[0020] Optionally, each of the barbs is inclined downwards along the side close to the connected clamping plate and towards the side away from the connected clamping plate.

[0021] By adopting the above technical solution and setting the barbs at an angle downwards, the clamping plate can achieve a full clamping process on the cloth bag during the clamping process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up an internal baffle, carbon black can form a vortex inside the filter bag, thereby reducing the phenomenon of carbon black entering the ash hopper and then being moved out of the ash hopper again, causing pollution to the surrounding environment.

[0024] 2. By setting up a clamping component, the filter bag can be fully clamped, thereby reducing the phenomenon of carbon black scattering caused by the filter bag moving during the process of guiding carbon black into the dust collection hopper. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.

[0029] This application discloses a dust-proof and ash-collecting hopper.

[0030] Example 1

[0031] Reference Figure 1A dust-proof hopper includes a dust collection hopper 1, the lower end of which gradually tapers towards the center from top to bottom. A feed inlet 11 penetrating the top wall of the dust collection hopper 1 is provided at the middle of the upper end. A discharge pipe 2 is fixedly connected to the middle of the lower end of the dust collection hopper 1, and the discharge pipe 2 communicates with the interior of the dust collection hopper 1.

[0032] The dust collection hopper 1 has an inner partition 3 inside, which is parallel to and spaced apart from the inner wall of the dust collection hopper 1.

[0033] In actual use, the filter bag is inserted into the dust collection hopper 1, and the negative pressure suction pipe is connected to the discharge pipe 2. Then, the carbon black is guided into the dust collection hopper 1 through the filter bag. After entering the filter bag, the carbon black floats upward between the inner wall and the inner partition of the dust collection hopper 1. After touching the top wall of the dust collection hopper 1, it moves downward along the side of the inner partition away from the inner wall of the dust collection hopper 1, thereby constraining the carbon black inside the dust collection hopper 1 and making it difficult for the carbon black to move out of the dust collection hopper 1.

[0034] The implementation principle of Example 1 is as follows: after the cloth bag is inserted into the ash hopper 1, the carbon black moves in a vortex shape around the inner partition of the ash hopper 1, and is then absorbed into the suction pipe, thereby realizing the collection process of carbon black inside the pyrolysis furnace.

[0035] Example 2

[0036] Reference Figure 2 The difference between this embodiment and Embodiment 1 is that a clamping component 4 is provided on the upper side of the dust suction hopper 1 near the feed inlet 11. The clamping component 4 is used to clamp the cloth bag inserted into the feed inlet 11.

[0037] By setting the clamping component 4, the filter bag can be clamped, thereby enabling the filter bag to stably guide carbon black into the ash hopper 1, which facilitates the process of collecting carbon black from inside the pyrolysis furnace.

[0038] The clamping assembly 4 includes two clamping plates 41 located opposite each other at the feed inlet 11. Each clamping plate 41 is C-shaped, and the C-shaped opening of each clamping plate 41 faces the feed inlet 11. The lower side of each clamping plate 41 is slidably connected to the top wall of the dust collection hopper 1.

[0039] Two clamping plates 41 are fixedly connected to the middle position on opposite sides with clamping screws 42, each clamping screw 42 being arranged parallel to the top wall of the dust suction hopper 1. Each clamping screw 42 is threadedly fitted with a driven pulley 43, and each driven pulley 43 has a drive pulley 44 on one side. Each driven pulley 43 and the adjacent drive pulley 44 are fitted with the same connecting belt 45.

[0040] Two drive pulleys 44 are connected through and fixedly connected to the same drive shaft 47, and a handwheel 471 is fixedly connected to one end of the drive shaft 47.

[0041] After the fabric bag is inserted into the feed inlet 11, the handwheel 471 is turned. The handwheel 471 rotates, causing the drive shaft 47 to rotate, which in turn rotates the two connected drive pulleys 44. The drive pulleys 44 rotate, causing the connected connecting belt 45 to rotate, which in turn rotates the connected driven pulley 43. The driven pulley 43 rotates, causing the connected clamping screw 42 to move, which in turn moves the clamping plate 41. The clamping plate 41 then clamps the fabric bag, thus achieving the process of clamping the fabric bag.

[0042] Each clamping plate 41 has a pressure plate 46 at both ends. Each pressure plate 46 is spaced apart from the side wall of the end of the adjacent clamping plate 41, and a compression spring 461 is fixedly connected between each pressure plate 46 and the side wall of the end of the adjacent clamping plate 41.

[0043] By setting up pressure plates 46 and compression springs 461, as the two clamping plates 41 move closer to each other, the two pressure plates 46 first come into contact with the cloth bag, thus achieving preliminary fixation of the cloth bag by the pressure plates 46. Then, the two clamping plates 41 fully clamp the cloth bag.

[0044] Multiple barbs 411 are fixedly connected to the opposite sides of the two clamping plates 41. Each barb 411 is inclined from the side close to the clamping plate 41 to the side away from the clamping plate 41 and towards the side close to the dust hopper 1.

[0045] By setting multiple barbs 411, during the process of clamping the cloth bag by the two clamping plates 41, the barbs 411 on the side of the clamping plate 41 closest to the cloth bag abut against the cloth bag, and the barbs 411 are set downward, so that the clamping plate 41 can clamp the cloth bag more stably, thereby enabling the carbon black to be stably guided into the dust collection hopper 1 when the cloth bag guides the carbon black into the dust collection hopper 1.

[0046] The implementation principle of Example 2 is as follows: When it is necessary to guide carbon black into the dust collection hopper 1, the cloth bag is inserted into the dust collection hopper 1. Then, the handwheel 471 is turned, and the handwheel 471 drives the connected drive shaft 47 to rotate during the rotation.

[0047] During the rotation of the drive shaft 47, the two drive pulleys 44 are driven to rotate. During the rotation of the drive pulleys 44, the two driven pulleys 43 are driven to rotate. During the rotation of the two driven pulleys 43, the connected clamping screw 42 is moved. During the movement of the clamping screw 42, the clamping plate 41 and the pressure plate 46 are driven to clamp the cloth bag, thereby realizing the stable clamping process of the cloth bag.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
