Description

Technical Field

[0001] The present application relates to the field of waste treatment equipment, and in particular to a feeding system for domestic waste treatment equipment. Background Art

[0002] In the process of urbanization, garbage, as a byproduct of urban metabolism, was once a burden on urban development, with many cities around the world experiencing a situation of being surrounded by garbage. Today, however, garbage is considered an inexhaustible "urban mineral deposit" with the greatest potential for development, a "misplaced resource." This represents both a deepening understanding of garbage and an inevitable requirement for urban development. A common method of waste disposal involves feeding the garbage through a feed inlet into a pyrolysis furnace for crushing and combustion. During the combustion process, the garbage releases heat, which can then be recovered to provide heating or power generation for the entire city, achieving resource recycling.

[0003] When garbage is put into the furnace, due to the uneven feeding speed and quantity of garbage, the pyrolysis reaction of the garbage in the furnace is also uneven, which affects the garbage treatment quality and energy recovery, and reduces the energy recovery rate after pyrolysis of the garbage. Summary of the Invention

[0004] In order to improve the uneven feeding of garbage and increase the energy recovery rate during garbage pyrolysis, the present application provides a feeding system for domestic waste treatment equipment.

[0005] The present application provides a domestic waste treatment equipment feeding system adopting the following technical solutions:

[0006] A feeding system for domestic waste treatment equipment, comprising

[0007] furnace body;

[0008] A feed pipe, one end of which is connected to the furnace body and fixed along the length direction, and the other end of which is provided with a feed port opening upward;

[0009] The feeding screw is rotatably installed in the feeding pipe and arranged along the length direction of the feeding pipe;

[0010] The driving motor is installed in the feeding pipe and the output shaft is coaxially fixedly connected with the feeding screw.

[0011] By adopting the above technical solution, when garbage is fed into the domestic waste treatment equipment for processing, the garbage is first placed into the feed port. The drive motor drives the feed screw to rotate, which simultaneously drives the garbage through the feed pipe until the garbage moves into the furnace body. The speed and amount of garbage entering the furnace are determined by the rotation speed of the screw, thereby improving the uneven garbage feeding. Furthermore, when the garbage is fed evenly, the reaction in the furnace is more uniform, and the waste pyrolysis generates more energy, thereby improving the energy recovery rate during the waste pyrolysis.

[0012] Preferably, the feed pipe is connected to and fixed with a feed funnel at the feed inlet, and the opening of the feed funnel is arranged upward.

[0013] By adopting the above technical solution, the feed funnel, on the one hand, expands the feeding area of the garbage entering the feed pipe, so as to facilitate the pouring of the garbage into the feed pipe; on the other hand, after the garbage is poured into the feed funnel, the piles of garbage will be spread out in the feed funnel in a trumpet shape, so as to improve the uniformity of the garbage entering the feed pipe.

[0014] Preferably, the feed pipe is arranged at an end facing away from the furnace body and tilted downward.

[0015] By adopting the above technical solution, when the garbage enters the feed pipe, due to the inclined layout of the feed pipe, the garbage can only move in the feed pipe by the rotation of the feeding screw, and the garbage enters the feed pipe under the action of its own gravity and the pressure from above, so as to avoid garbage blockage that prevents the garbage from entering the feed pipe, thereby causing uneven feeding, thereby further improving the uniformity of garbage feeding.

[0016] Preferably, a feed slope is provided on the inner wall of the furnace body communicating with the feed pipe, and the feed slope is located below the feed pipe and slopes downward in a direction away from the feed pipe.

[0017] By adopting the above technical solution, the area where garbage enters the furnace is expanded through the feeding channel, so that garbage can enter the furnace body more easily, thereby reducing the risk of garbage clogging in the furnace body.

[0018] Preferably, a sealing assembly for sealing the furnace body is provided between the furnace body and the feed pipe.

[0019] By adopting the above technical solution, when the garbage begins to be pyrolyzed in the furnace, the sealing component isolates the furnace body and the feed pipe and seals the furnace body, thereby reducing energy leakage in the furnace body. When the furnace body needs to be fed, the sealing component releases the isolation between the furnace body and the feed pipe to facilitate the garbage to enter the furnace body through the feed pipe.

[0020] Preferably, the sealing assembly includes

[0021] a sealing frame installed between the feed pipe and the furnace body, wherein a sealing passage communicating with the feed pipe and the furnace body is formed in the sealing frame;

[0022] A sealing door is arranged vertically and slidably disposed in the sealing frame;

[0023] A sealing hydraulic cylinder is mounted on the sealing frame. An output shaft of the sealing hydraulic cylinder is connected to the sealing door and is used to drive the sealing door to slide into or out of the sealing channel.

[0024] By adopting the above technical solution, when the furnace body and the feed pipe are isolated, the sealing hydraulic cylinder is started, and the sealing hydraulic cylinder drives the sealing door to slide into the sealing channel, thereby closing the furnace body. When the furnace body and the feed pipe are released from isolation, the sealing hydraulic cylinder drives the sealing door to slide away from the sealing channel, so that the furnace body and the feed pipe are connected, thereby achieving sealing and connection of the furnace body.

[0025] Preferably, the sealing door includes

[0026] a first support bar abutting against one of the vertically arranged side walls of the sealing channel;

[0027] a second support bar abutting against another side wall of the sealing channel arranged vertically and sliding in a direction approaching or moving away from the first support bar;

[0028] a door surface, the door surface being foldable, the door surface being mounted on the first support bar and the second support bar and being located between the first support bar and the second support bar;

[0029] The telescopic slide rod is connected to the output shaft of the sealed hydraulic cylinder at one end along its length, and slides through the first support bar in a direction perpendicular to the first support bar at the other end along its length and is detachably connected to the second support bar.

[0030] By adopting the above technical solution, when the sealing door slides into the sealing channel, the sealing hydraulic cylinder pushes the telescopic slide rod to drive the second support bar to slide in the direction away from the first support bar, and the door surface extends as the second support bar slides until the second support bar abuts against the side wall of another sealing channel away from the first support bar, so that the entire door surface is sealed against the sealing channel to achieve the sealing effect of the sealing door.

[0031] Preferably, two groups of sealing doors are provided, and the two groups of sealing doors are spaced apart along the length direction of the sealing channel. A repair cavity connected to the sealing channel is opened on the sealing frame, and a sealing cover is detachably connected to the repair cavity, and the second support bar abuts against the sealing cover.

[0032] By adopting this technical solution, the two sets of sealing doors not only enhance the sealing performance of the sealing assembly, but also, if one sealing door is damaged, the other sealing door can still function normally, thus not hindering the normal operation of the domestic waste treatment equipment. Furthermore, by removing the sealing cover, workers can remove, repair, or replace the damaged sealing door through the repair chamber, thus performing online maintenance.

[0033] Preferably, the telescopic sliding rods on the two sets of sealing doors are both connected and fixed to the output shaft of the sealing hydraulic cylinder.

[0034] By adopting the above technical solution, two sets of sealing doors are driven to move simultaneously by a sealing hydraulic cylinder, so that the two sealing doors can move synchronously, thereby improving the utilization rate of the sealing hydraulic cylinder, simplifying the number and weight of parts of the overall equipment, and optimizing the structural performance of the overall equipment.

[0035] Preferably, a horizontally arranged anti-slip strip is detachably installed in the sealing channel, and the two ends of the anti-slip strip along the length direction are respectively abutted against the first support strip and the sealing cover, and the second support strip is slidably connected to the anti-slip strip along the length direction of the anti-slip strip.

[0036] By adopting the above technical solution, the anti-slip bar not only limits the position of the first support bar, but also makes it possible to locate the first support bar between the side wall of the sealing channel and the anti-slip bar, thereby preventing the sealing performance of the sealing door from being reduced due to the position movement of the first support bar. On the other hand, it facilitates the removal of the sealing door. When removing the sealing door, the sealing cover is first opened, the anti-slip bar is then moved out of the sealing channel, and the second support bar is removed from the telescopic slide rod. After that, the entire sealing door can be removed from the sealing channel for easy maintenance or replacement.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. The driving motor drives the conveying screw to rotate, which drives the garbage to move in the feeding pipe. The speed and amount of garbage entering the furnace are determined by the rotation speed of the screw, thereby improving the uneven feeding of garbage and improving the energy recovery rate during garbage pyrolysis;

[0039] 2. The feed funnel not only expands the feeding area of the garbage into the feed pipe, but also spreads the garbage into a trumpet shape in the feed funnel after the garbage is poured into the feed funnel, so as to improve the uniformity of the garbage entering the feed pipe.

[0040] 3. Since the feed pipe is arranged at an angle, the garbage can only move in the feed pipe by the rotation of the feeding screw, and the garbage enters the feed pipe under the action of its own gravity and the pressure from above, so as to avoid garbage blockage that prevents the garbage from entering the feed pipe, thereby causing uneven feeding, thereby further improving the uniformity of garbage feeding.

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1-6 This application is described in further detail.

[0049] The embodiment of the present application discloses a feeding system for domestic waste treatment equipment. Figure 1 and Figure 2 The feeding system includes a furnace body 1, a feeding pipe 2, a feeding screw 3, a driving motor 4, a feeding funnel 5 and a sealing assembly 6.

[0050] Among them Figure 2As shown, the furnace body 1 is a hollow box, one end of the feed pipe 2 is connected and fixed to the furnace body 1, and the other end of the feed pipe 2 is located outside the furnace body 1 and has a feed port. The feed funnel 5 is connected and fixed to the feed pipe 2 through the feed port. The feed funnel 5 is arranged with its opening upwards to facilitate the placement of garbage into the feed funnel 5. Figure 3 As shown, the feeding screw 3 is installed in the feeding pipe 2 and rotates along the length direction of the feeding pipe 2. The driving motor 4 is installed in the feeding pipe 2, and the output shaft is fixed coaxially with the feeding screw 3. The feeding screw 3 is driven by the driving motor 4 to rotate in the feeding pipe 2, so that the garbage entering the feeding funnel 5 can be evenly moved into the furnace body 1 as the feeding screw 3 rotates.

[0051] Throughout the entire device, the speed and amount of garbage entering the furnace are determined by the rotational speed of the feed screw 3, thereby improving the unevenness of garbage feeding. Furthermore, the more uniform the garbage feeding, the more uniform the pyrolysis reaction within the furnace 1, and the more energy is generated by the pyrolysis, thereby improving the energy recovery rate during the pyrolysis of the garbage.

[0052] In addition, the sealing assembly 6 is located at the connection between the furnace body 1 and the feed pipe 2 and is installed on the furnace body 1. The sealing assembly 6 can seal the furnace body 1 when the furnace body 1 pyrolyzes the garbage. On the one hand, it isolates the furnace body 1 and the feed pipe 2 to prevent the garbage from entering the furnace body 1. On the other hand, it seals the furnace body 1, thereby reducing energy leakage in the furnace body 1.

[0053] Reference Figure 2 A feed slope 11 is formed on the inner wall of the furnace body 1 where the feed pipe 2 connects. The feed slope 11 is located below the connection point between the feed pipe 2 and the furnace body 1 and gradually slopes downward away from the feed pipe 2. This expands the area where garbage enters the furnace body 1, facilitating its entry and reducing the risk of garbage clogging the furnace body 1.

[0054] Reference Figure 2 and Figure 3 The end of the feed pipe 2 facing away from the furnace body 1 is tilted downward. This allows the garbage to move in the feed pipe 2 only through the rotation of the feeding screw 3. The garbage enters the feed pipe 2 under the dual forces of its own gravity and the pressure of the garbage above, avoiding garbage clogging at the feed inlet, which would prevent the garbage from entering the feed pipe 2 and causing uneven feeding. This further improves the uniformity of garbage feeding.

[0055] Reference Figure 4 and Figure 5 The sealing assembly 6 includes a sealing frame 61 , a sealing door 62 , a sealing hydraulic cylinder 63 and a sealing cover 64 .

[0056] The sealing frame 61 is mounted on the furnace body 1 and fixedly connected to the feed pipe 2. A sealed passage 611 is defined within the sealing frame 61, connecting the interior of the furnace body 1 and the feed pipe 2. A sealing door 62 is mounted within the sealed passage 611. A sealing hydraulic cylinder 63 is mounted on the sealing frame 61, and its output shaft is connected to the sealing door 62, allowing it to slide into or out of the sealed passage 611, thereby controlling the connection between the furnace body 1 and the feed pipe 2. A repair chamber 612 is defined in the sealing frame 61, connecting the sealed passage 611 with the outside. A sealing cover 64 is inserted into the repair chamber 612 and covers the opening of the repair chamber 612. The sealing cover 64 is bolted to the sealing frame 61 and arranged opposite the sealing hydraulic cylinder 63. The sealing hydraulic cylinder 63 is mounted on the outside of the sealing frame 61 and arranged horizontally, allowing easy repair of the sealing hydraulic cylinder 63 and the sealing door 62 through the repair chamber 612.

[0057] In addition, two sets of sealing doors 62 are provided. The two sealing doors 62 are installed in the sealing channel 611 at intervals along the length of the sealing channel 611, thereby enhancing the sealing performance of the sealing assembly 6 on the furnace body 1. Moreover, if one sealing door 62 is damaged, the other sealing door 62 can still seal the furnace body 1. The staff only needs to repair and replace the damaged sealing door 62, facilitating online maintenance of the equipment.

[0058] The output shaft of the sealing hydraulic cylinder 63 slides through the sealing frame 61 and is mounted with a limit slide bar 65. A limit slide groove 614 is defined on the sealing frame 61, along the direction in which the output shaft of the sealing hydraulic cylinder 63 is positioned, for the limit slide bar 65 to slide. Both sealing doors 62 are connected to the limit slide bar 65. The sealing hydraulic cylinder 63 drives the limit slide bar 65 to slide within the limit slide groove 614, thereby simultaneously driving both sealing doors 62 to slide in or out of the sealing passage 611. This simplifies the structure of the sealing assembly 6 while also improving the utilization of the sealing hydraulic cylinder 63 and optimizing the overall structure of the device.

[0059] like Figure 4 and Figure 5 As shown, the sealing door 62 includes a first support bar 621 , a second support bar 622 , a door surface 623 and a telescopic sliding rod 624 .

[0060] The first support bar 621 is arranged vertically and conflicts with one of the side walls of the sealing channel 611 arranged vertically. A first limiting groove 613 is provided on the cavity wall of the sealing channel 611 to which the first support bar 621 is mutually clamped. The first support bar 621 is located in the first limiting groove 613. The second support bar 622 is arranged relative to the first support bar 621 along a layout direction perpendicular to the sealing channel 611. A second limiting groove 641 is provided on the end face of the sealing cover 64 close to the first support bar 621 to which the second support bar 622 is clamped.

[0061] The door surface 623 is formed of a foldable material and is mounted on the first support bar 621 and the second support bar 622. The door surface 623 is located between the first support bar 621 and the second support bar 622 to facilitate sealing the sealing channel 611. The telescopic slide 624 is arranged in a direction parallel to the output shaft of the sealing hydraulic cylinder 63, and one end along the length direction is connected and fixed to the limit slide 65. The other end of the telescopic slide 624 along the length direction slides through the first support bar 621 and the second support bar 622.

[0062] The second support bar 622 is rotatably connected to a nut threadedly connected to the telescopic slide 624. When the telescopic slide 624 is driven to slide by the sealing hydraulic cylinder 63, the telescopic slide 624 can drive the second support bar 622 to slide in a direction close to or away from the first support bar, thereby controlling the connection state of the sealed channel 611.

[0063] When one of the sealing doors 62 is damaged, in order to detach the damaged sealing door 62 from the sealing frame 61, as shown in FIG. Figure 5 and Figure 6 As shown, each sealing door 62 is connected to two anti-slip strips 66 .

[0064] Two anti-slip bars 66 are located at the top and bottom of the door surface 623, respectively. The anti-slip bars 66 slide against the door surface 623 to improve the sealing performance of the door surface 623 against the sealed passage 611. One end of the anti-slip bar 66 is fixed to the sealing cover 64 along its length, and the other end of the anti-slip bar 66 is engaged with the first support bar 621 along its length. The first support bar 621 has an anti-slip groove 6211 on the side wall of the sealing cover 64, which is slidably engaged with the anti-slip bar 66. The second support bar 622 has an anti-slip groove 6221 that is slidably connected to the anti-slip bar 66. The second support bar 622 can slide along the length of the anti-slip bar 66.

[0065] When the sealing door 62 is removed, the sealing cover 64 is first separated from the repair chamber 612. At the same time, the anti-detachment slide groove 6221 is separated from the repair chamber 612 together with the sealing cover 64. The second support bar 622 is detached from the telescopic slide rod 624. The second support bar 622 is pulled to slide from the repair chamber 612 away from the sealing channel 611. During the movement of the second support bar 622, the door surface 623 and the first support bar 621 are driven to move out of the repair chamber 612 together, thereby realizing the removal of the sealing door 62.

[0066] The implementation principle of the feeding system of a domestic waste treatment equipment in an embodiment of the present application is as follows: when garbage is put into the domestic waste treatment equipment for treatment, the garbage is first put into the feeding funnel 5, and then the feeding screw 3 is driven to rotate by the driving motor 4. While the feeding screw 3 rotates, it drives the garbage to move in the feeding pipe 2, and then the sealing hydraulic cylinder 63 is started, and the second support bar 622 moves in the direction close to the first support bar 621 until the door face 623 is folded to the maximum extent, so that the sealing channel 611 is in a connected state, and then the garbage is moved into the furnace body 1 through the feeding screw 3, and finally the sealing hydraulic cylinder 63 drives the second support bar 622 to move in the direction away from the first support bar 621, and the door face 623 stretches until the second support bar 622 slides and is inserted into the second limit groove 641, finally improving the uneven garbage feeding and improving the energy recovery rate during garbage pyrolysis.

[0067] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
