Abstract
Description
Technical Field
[0001] The utility model belongs to the field of carbonization furnaces, and in particular relates to a material discharging structure for a carbonization furnace. Background Art
[0002] The carbonization furnace is used to carbonize the sludge. During the carbonization process, the carbonization furnace is in a high temperature state, which evaporates the water in the sludge while retaining the carbon value in the sludge to the maximum extent. The organic matter in the sludge is carbonized, and the sludge after carbonization can be recycled for a second time, and the volume of the sludge after carbonization becomes smaller. Therefore, when recycling the carbonized sludge, the smaller carbonized material is not only inconvenient for subsequent use, but also because of its small size, it is not easy to separate it from the larger carbonized material after discharging. Utility Model Content
[0003] In view of the above-mentioned deficiencies, the utility model provides a discharging structure for a carbonization furnace, so that the recovered materials are more complete as a whole.
[0004] The utility model is realized by the following technical solutions:
[0005] A discharge structure for a carbonization furnace, the carbonization furnace comprises a furnace body, a feed port and a discharge port connecting the outside with the inside of the furnace body are arranged on the furnace body, along the direction from the feed port to the discharge port, a carbonization section connected with the feed port and a discharge section connecting the carbonization section with the discharge port are sequentially formed inside the furnace body, the discharge structure is arranged in the discharge section, the height of the carbonization section gradually decreases along the direction approaching the discharge section; the discharge structure comprises a transfer member and a driving member for driving the transfer member to move, the driving member comprises a driving wheel and a plurality of planetary wheels arranged along the circumference of the driving wheel, each planetary wheel corresponds to a transfer member; the transfer member comprises a driven wheel meshed with the corresponding planetary wheel and a push plate connected to the driven wheel, the push plate extends from the connection point between the carbonization section and the discharge section to the carbonization section, and a discharge hole is formed on the bottom wall of the discharge section. The formed carbonized material can be diverted through the discharge hole. Since the carbonized material formed after carbonization is relatively fragile, it will produce debris due to collision during discharge. The generated debris can fall from the discharge hole and be separated from the complete carbonized material, making the material recovered from the discharge port more complete as a whole. At the same time, the movement of the carbonized material can be driven by rotation, which can also extend the movement distance of the carbonized material, thereby achieving better separation.
[0006] Furthermore, the discharge structure also includes a storage box located at the rear side of the discharge section and a recovery box located at the lower side of the discharge section. The recovery box is connected to the discharge section through a feed hole. The size of the feed hole is smaller than the size of the material in the storage box. Since the feed hole can separate the slag from the whole piece of carbonized material, the carbonized material moves into the storage box under the drive of the push plate, and the separated slag falls into the recovery box through the feed hole, so that the slag can be recovered, for example, it can be used as fuel for heating during carbonization, so as to achieve full utilization.
[0007] Furthermore, each push plate is formed with a sieve hole along its rotation direction, and the size of the sieve hole is smaller than the size of the material in the storage box. Since the push plate can push the carbonized material to move, by setting the sieve hole, when the push plate drives the carbonized material to move, the debris mixed between the carbonized materials can also be screened by the sieve hole, and when the carbonized material is pushed to move, the position of the carbonized material will also change, and the debris that does not pass through the sieve hole can also move in the gap between the carbonized materials, and finally fall on the bottom wall of the discharge section, so as to be recovered into the recovery box through the discharge hole.
[0008] Furthermore, along the rotation direction of the push plate, the rear side of the push plate is connected with a baffle, and the projection of the sieve holes is located at the baffle. The debris entering between the baffle and the push plate through the sieve holes will fall under the action of gravity, and the area between the baffle and the push plate is also located at the discharge section, that is, the debris here can also be recovered into the recovery box through the discharge hole.
[0009] Furthermore, the distance between the push plate and the baffle is l, the distance between adjacent push plates is L, and l:L is 1:3 to 1:5. If the ratio between the two is too small, that is, the distance between the push plate and the baffle is too small, the slag will be easily stuck in the gap and cannot fall when entering between the push plate and the baffle, affecting the recovery of the slag. If the ratio between the two is too large, that is, the distance between the push plate and the baffle is too large, it will not only cause a waste of space, making the space between the push plate and the baffle much larger than the space occupied by the slag, but also compress the distance between adjacent push plates, resulting in a reduction in the space used for pushing materials and reducing the pushing efficiency.
[0010] Furthermore, a plurality of sieve holes are formed on the push plate, and the number of the sieve holes gradually decreases from top to bottom. Since the slag will fall along the gaps between the carbonized materials under the action of gravity, the sieve holes are more densely distributed at the bottom of the push plate, which is more conducive to the separation of the slag and the carbonized materials.
[0011] Furthermore, there are four planetary wheels, and the four planetary wheels are equally spaced along the circumference of the driving wheel. Correspondingly, there are also four pusher plates, thereby ensuring that the distance between adjacent pusher plates can meet the temporary storage of carbonized materials and avoid the carbonized materials from being squeezed between adjacent pusher plates.
[0012] Furthermore, the end of each push plate is bent to form a bent section, and the bending direction of the bent section is the same as the rotation direction of the push plate. Since the push plate will extend into the carbonization section, the carbonized material in the carbonization section will be removed, and the push plate will also rotate circumferentially relative to the driving wheel under the drive of the planetary wheel and the driven wheel, therefore, by providing the bent section, and the rotation direction of the push plate is the same as the bending direction of the bent section, it will be more conducive to taking out the carbonized material during the rotation process.
[0013] Furthermore, a partition is provided at the connection between the carbonization section and the discharge section, and the bending section is a flexible bending section. Since the discharge structure is provided at the discharge section connected to the carbonization section, and the temperature of the carbonization section is relatively high when carbonizing the sludge, in order to avoid the temperature at the carbonization section affecting the discharge structure during the carbonization process, a partition is provided at the connection between the carbonization section and the discharge section. During the carbonization process, the partition separates the carbonization section from the discharge section, thereby preventing the discharge structure from being affected by high temperature. When cooling is completed and discharge is performed, the partition can be removed, so that the carbonization section is connected to the discharge section and discharge is performed. Since the push plate partially extends to the carbonization section, and the bending section is located at the end of the push plate, the bending section is the part extending to the carbonization section. Therefore, the bending section is a flexible structure, so that when the partition separates the carbonization section and the discharge section, the bending section can be deformed and is located as a whole in the discharge section, so that the partition can better separate the carbonization section and the discharge section.
[0014] Furthermore, the discharge structure also includes a pusher, which is located on the side of the carbonization section away from the discharge section. Since the carbonization section is usually filled up to improve the efficiency of carbonization during sludge carbonization, the pusher can better move the carbonized material from the carbonization section to the discharge section and realize discharge.

[0023] like Figure 1 and Figure 2 The carbonization furnace is used for carbonizing sludge, and during the carbonization process, the carbonization furnace is in a high temperature state, so that the water in the sludge evaporates, while the carbon value in the sludge is retained to the maximum extent, and the organic matter in the sludge is carbonized. The carbonized sludge can be recycled for secondary use, and the volume of the carbonized sludge becomes smaller; wherein the carbonization furnace includes a furnace body 1, and the furnace body 1 is provided with a feed port 11 and a discharge port 12 for connecting the outside with the inside of the furnace body 1. 2. Along the direction from the feed inlet 11 to the discharge port 12, the interior of the furnace body 1 is sequentially formed with a carbonization section 13 connected with the feed inlet 11, and a discharge section 14 connected with the carbonization section 13 and the discharge port 12. The sludge is fed into the carbonization section 13 in the furnace body 1 through the feed section and heated to form carbonized products, and the carbonized products are finally discharged through the discharge port 12. During the discharge process, the discharge structure can move the carbonized products in the carbonization section 13 to the discharge port 12 through the discharge section 14, and finally move them out.
[0024] In the present application, the discharging structure is arranged at the discharging section 14, and the height of the carbonization section 13 gradually decreases in the direction approaching the discharging section 14; the discharging structure includes a transfer member and a driving member for driving the transfer member to move, the driving member includes a driving wheel 21 and a plurality of planetary wheels 22 arranged along the circumference of the driving wheel 21, and each planetary wheel 22 corresponds to a transfer member; the transfer member includes a driven wheel 31 meshed with the corresponding planetary wheel 22 and a push plate 32 connected to the driven wheel 31, the push plate 32 extends from the connection point between the carbonization section 13 and the discharging section 14 to the carbonization section 13, and the bottom wall of the discharging section 14 is formed with a discharge hole 141; during the discharging process, since the push plate 32 will extend to the carbonization section 13, when the push plate 32 rotates, it will push the carbonized The carbonized material in the section 13 rotates into the discharge section 14 and drives the carbonized material to move toward the discharge port 12, wherein the driving member is composed of a driving wheel 21 and a planetary wheel 22, wherein the driving wheel 21 can rotate around the rotation axis, and during the rotation process, it will drive the planetary wheel 22 to rotate circumferentially around the driving wheel 21, thereby changing the position of the planetary wheel 22, and the material transfer member is provided with a driven wheel 31 meshing with the correspondingly connected planetary wheel 22. When the planetary wheel 22 moves, it not only rotates itself, but also rotates along the driving wheel 21. Therefore, the driven wheel 31 is meshed with the planetary wheel 22. When the planetary wheel 22 rotates circumferentially, it will also move with the driven wheel 31, thereby realizing the movement of the push plate 32, and the push plate 32 can drive the position of the carbonized material to change when it moves.
[0025] At the same time, a discharge hole 141 is formed on the bottom wall of the discharge section 14, and the formed carbonized material can be diverted through the discharge hole 141. Since the carbonized material formed after carbonization is relatively fragile, it will produce debris due to collision during discharge, and the generated debris can fall from the discharge hole 141 and be separated from the complete carbonized material, so that the material recovered by the discharge port 12 is more complete as a whole; at the same time, the movement of the carbonized material can be driven by rotation, and the movement distance of the carbonized material can be extended, thereby achieving better separation.
[0026] Among them, the push plate 32 is meshed and connected with the planetary wheel 22 through the driven wheel 31. Specifically, the driven wheel 31 is provided with a driven shaft plugged into the push plate 32, and the driven shaft can rotate relative to the push plate 32. Therefore, when the planetary wheel 22 rotates and drives the driven wheel 31 to rotate, the driven wheel 31 will drive the driven shaft to rotate, and the push plate 32 will not rotate under the drive of the driven wheel 31, but will rotate as a whole around the driving wheel 21 under the drive of the driven wheel 31 and push the material to move.
[0027] In the present application, the end of each push plate 32 is bent to form a bent section 322, and the bending direction of the bent section 322 is the same as the rotation direction of the push plate 32; since the push plate 32 will extend into the carbonization section 13, the carbonized material in the carbonization section 13 will be removed, and the push plate 32 will also rotate circumferentially relative to the driving wheel 21 under the drive of the planetary gear 22 and the driven wheel 31. Therefore, by setting the bent section 322, and the rotation direction of the push plate 32 is the same as the bending direction of the bent section 322, it will be more conducive to taking out the carbonized material during the rotation process.
[0028] Preferably, a partition 15 is provided at the connection between the carbonization section 13 and the discharge section 14, and the bending section 322 is a flexible bending section 322; since the discharge structure is provided at the discharge section 14 connected to the carbonization section 13, and the temperature of the carbonization section 13 is relatively high when carbonizing the sludge, in order to avoid the temperature at the carbonization section 13 affecting the discharge structure during the carbonization process, a partition 15 is provided at the connection between the carbonization section 13 and the discharge section 14. During the carbonization process, the partition 15 separates the carbonization section 13 from the discharge section 14, thereby preventing the discharge structure from being affected by the high temperature. When the cooling is completed and When discharging, the partition 15 can be removed so that the carbonization section 13 is connected to the discharging section 14, and discharging can be carried out. Since the push plate 32 partially extends to the carbonization section 13, and the bending section 322 is located at the end of the push plate 32, the bending section 322 is the part extending to the carbonization section 13. Therefore, the bending section 322 is a flexible structure, so that when the partition 15 separates the carbonization section 13 and the discharging section 14, the bending section 322 can be deformed and is located as a whole in the discharging section 14, so that the partition 15 can better separate the carbonization section 13 and the discharging section 14.
[0029] In the present application, the discharging structure also includes a pushing piece, which is located on the side of the carbonization section 13 away from the discharging section 14; because; when the sludge is carbonized, in order to improve the efficiency of carbonization, the carbonization section 13 is usually filled up, so by providing a pushing piece, the carbonized material can be better moved from the carbonization section 13 to the discharging section 14, and the discharging can be realized; and when the material is less, the material can be moved from the carbonization section 13 to the discharging section 14 under the action of gravity, and the discharging can be realized under the drive of the discharging structure.
[0030] It can be understood that the pushing piece plays an auxiliary role when the sludge to be processed is placed closely, in order to avoid jamming, which makes it impossible to move to the discharge section 14 under the action of gravity. However, when there is less material, the pushing piece may not be used, and the formed carbonized product is relatively fragile, so it is only assisted by the pushing piece to avoid excessive squeezing between the carbonized products, which may cause damage and affect the quality of the formed carbonized products.
[0031] In the present application, the discharging structure also includes a storage box 41 located at the rear side of the discharging section 14 and a recovery box located at the lower side of the discharging section 14. The recovery box is connected to the discharging section 14 through a discharge hole 141. The size of the discharge hole 141 is smaller than the size of the material in the storage box 41. Since the discharge hole 141 can separate the debris from the whole piece of carbonized material, the carbonized material moves into the storage box 41 driven by the push plate 32, and the separated debris falls into the recovery box through the discharge hole 141, thereby realizing the recovery of the debris, for example, it can be used as fuel for heating during carbonization, thereby achieving full utilization.
[0032] Preferably, the end of the discharge section 14 is recessed to form a feed trough, and the storage box 41 is arranged below the feed trough, so when the push plate 32 rotates around the driving wheel 21, it will move to the feed trough and push the screened carbonized material into the storage box 41 for recovery.
[0033] In the present application, each push plate 32 is formed with a sieve hole 321 along its rotation direction, and the size of the sieve hole 321 is smaller than the size of the material in the storage box 41; since the push plate 32 can push the carbonized material to move, by setting the sieve hole 321, when the push plate 32 drives the carbonized material to move, the debris mixed between the carbonized materials can also be screened by the sieve hole 321, and when the carbonized material is pushed to move, the position of the carbonized material will also change, and the debris that does not pass through the sieve hole 321 can also move in the gap between the carbonized materials, and finally fall on the bottom wall of the discharge section 14, so as to be recovered into the recovery box through the discharge hole 141.
[0034] Along the rotation direction of the push plate 32, the rear side of the push plate 32 is connected to the baffle plate 33, and the projections of the sieve holes 321 are all located at the baffle plate 33; a space for temporarily storing debris is formed between the baffle plate 33 and the push plate 32 to prevent the debris from being mixed into the carbonized material again, and the debris entering between the baffle plate 33 and the push plate 32 through the sieve holes 321 will fall under the action of gravity, and the area between the baffle plate 33 and the push plate 32 is also located at the discharge section 14, that is, the debris here can also be recovered into the recovery box through the discharge hole 141.
[0035] Preferably, the distance between the push plate 32 and the baffle plate 33 is l, the distance between adjacent push plates 32 is L, and l:L is 1:3 to 1:5; if the ratio between the two is too small, that is, the distance between the push plate 32 and the baffle plate 33 is too small, the slag will easily get stuck in the gap and cannot fall when entering between the push plate 32 and the baffle plate 33, affecting the recovery of the slag; if the ratio between the two is too large, that is, the distance between the push plate 32 and the baffle plate 33 is too large, it will not only cause a waste of space, making the space between the push plate 32 and the baffle plate 33 much larger than the space occupied by the slag, but also compress the distance between adjacent push plates 32, resulting in a reduction in the space used for pushing materials and a reduction in pushing efficiency.
[0036] It can be understood that since the push plate 32 rotates along the circumference of the driving wheel 21 when pushing materials, the distance between the push plate 32 and the baffle 33 is the distance in the circumferential direction of the driving wheel 21. Similarly, the distance between adjacent push plates 32 is also the distance in the circumferential direction of the driving wheel 21.
[0037] In the present application, a plurality of sieve holes 321 are formed at the push plate 32, and the number of the sieve holes 321 gradually decreases from top to bottom; since the slag will fall along the gaps between the carbonized materials under the action of gravity, the sieve holes 321 are more densely distributed in the lower part of the push plate 32, which is more conducive to the separation between the slag and the carbonized materials.
[0038] Preferably, there are four planetary wheels 22 , and the four planetary wheels 22 are equally spaced along the circumference of the driving wheel 21 ; correspondingly, there are also four pusher plates 32 , thereby ensuring that the distance between adjacent pusher plates 32 can meet the temporary storage of carbonized materials and avoid squeezing of carbonized materials between adjacent pusher plates 32 .
[0039] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
