Description

Technical Field

[0001] This utility model relates to the technical field of fly ash treatment, and in particular to a fly ash collection and treatment device for industrial waste incineration. Background Technology

[0002] The incineration of industrial waste and municipal solid waste produces a large amount of fly ash, which contains dioxins, heavy metals and organic pollutants, causing great harm to the environment and human health. Therefore, fly ash collection devices must be installed during the incineration process to prevent pollutants from being discharged back into the environment.

[0003] During the collection and storage of fly ash, its small particle size and loose structure result in a low bulk density (usually only 0.3-0.5 g / cm³), requiring storage space several times the volume of the solid, which significantly increases storage costs.

[0004] To address this issue, existing treatment technologies mostly employ mechanical compression, which involves repeatedly applying static pressure to the fly ash in the collection box using a hydraulic extrusion plate to form a dense mass before transferring it to a storage silo. However, while this method can continuously process fly ash, as the thickness of the compressed fly ash layer increases, the pressure transmission from the extrusion plate to the fly ash decreases sharply, thus affecting the volume reduction effect. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose an industrial waste incineration fly ash collection and treatment device that can continuously compress fly ash without affecting the compression and volume reduction effect of fly ash.

[0007] To achieve the above objectives, this utility model proposes an industrial waste incineration fly ash collection and treatment device, comprising an ash hopper, a compression chamber, and a transfer box. The compression chamber has conveying zones on both sides, with a compression zone between the two conveying zones. Each conveying zone has a feed hopper on its side away from the compression zone, connected to the ash hopper via a feed pipe. Each conveying zone has a screw conveying mechanism. The compression zone has openings on its symmetrical front and rear sides. The transfer box is movably disposed through the compression zone via a moving mechanism, and has multiple transfer holes arranged side-by-side inside. Each transfer hole has open sides, and the transfer holes cooperate with the compression zones.

[0008] In addition, the industrial waste incineration fly ash collection and treatment device proposed in the application may also have the following additional technical features:

[0009] Specifically, each of the openings is provided with a buffer cover on its outer side, and the buffer cover is provided with a channel for the transfer box to pass through, and the transfer box is slidably disposed in the channel by the moving mechanism.

[0010] Specifically, the length of the channel is not less than the length of the transfer hole.

[0011] Specifically, it also includes two unloading mechanisms, which are correspondingly arranged with the buffer cover. Each unloading mechanism includes a driving component and a push plate structure connected to the driving component. The buffer cover has through holes on both sides, which are perpendicular to the channel. The push plate structure includes two baffles and a connecting bracket for connecting the two baffles. The two baffles are slidably inserted into the corresponding through holes.

[0012] Specifically, the screw conveying mechanism includes a motor and screw auger blades connected to the output end of the motor. The screw auger blades and the motor are located on the inner and outer sides of the compression chamber, respectively, and the pitch of the screw auger blades gradually decreases from the feed box to the compression zone.

[0013] Specifically, the angle between the two conveying zones is greater than 0 degrees and less than or equal to 180 degrees.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] 1. This application employs two screw conveyor mechanisms to synchronously transport fly ash to the compression zone, and is equipped with a transfer box, which can promptly remove the fly ash blocks formed after compression, while simultaneously replacing the transfer holes in the compression zone. In this way, continuous compression processing of fly ash can be performed without affecting the compression and volume reduction effect, and the fly ash processing can proceed smoothly and efficiently, significantly improving the volume reduction effect.

[0016] 2. This application includes a buffer cover for temporary storage of the transfer orifice. This design ensures that the compression zone maintains good sealing performance during the replacement of the transfer orifice, thereby facilitating continuous and smooth compression of fly ash;

[0017] 3. This application includes a discharge mechanism that can promptly push out fly ash blocks from the transfer hole, completing the fly ash discharge operation. This function allows the transfer hole to quickly re-enter the compression zone to receive fly ash, ensuring the smooth operation of fly ash transfer.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following description, in conjunction with the accompanying drawings, describes an industrial waste incineration fly ash collection and treatment device according to an embodiment of the present invention, which can be applied to the collection and treatment of fly ash generated during the incineration of industrial waste, domestic waste, etc.

[0027] like Figures 1-4 As shown, the industrial waste incineration fly ash collection and treatment device of this utility model embodiment may include an ash hopper 10, a compression chamber 40, and a transfer box 50.

[0028] The compression chamber 40 has conveying zones 401 on both sides, with a compression zone 402 between the two conveying zones 401. Each conveying zone 401 has a feed hopper 4011 on its upper side away from the compression zone 402. The feed hopper 4011 is connected to the ash hopper 10 via a feed pipe 30. Each conveying zone 401 contains a screw conveyor mechanism 80. The screw conveyor mechanism 80 may include a motor 801 and screw auger blades 802 connected to the output end of the motor 801. The screw auger blades 802 and the motor 801 are located on the inner and outer sides of the compression chamber 40, respectively, and the pitch of the screw auger blades 802 gradually decreases from the feed hopper to the compression zone 402.

[0029] The spiral auger blade 802 described in this embodiment adopts a variable diameter design. Its inlet section (the side near the feed hopper 4011) has a large pitch, which can quickly transport the incoming fly ash and greatly improve the conveying efficiency. Its outlet section (the side near the compression zone 402) has a small pitch, which can gradually compress the transported fly ash and achieve preliminary compaction of the fly ash.

[0030] The compression zone 402 has openings 4021 on its front and rear symmetrical sides. Each opening 4021 has a buffer cover 60 on its outer side, and the buffer cover 60 has a channel 601 through which the transfer box 50 passes. The length of the channel 601 is not less than the length of the transfer hole 501. The channel 601 can temporarily store the transfer hole 501. During the replacement of the transfer hole 501, the compression zone 402 can maintain good sealing performance, thus facilitating continuous and smooth compression of fly ash.

[0031] Furthermore, the aforementioned industrial waste incineration fly ash collection and treatment device may also include two unloading mechanisms 90, which are correspondingly arranged with the buffer cover 60. The unloading mechanism 90 may include a driving component 902 and a push plate structure 901 connected to the driving component 902. The buffer cover 60 has through holes 602 on both sides, which are perpendicular to the channel 601. The push plate structure 901 may include two baffles 9011 and a connecting frame 9012 for connecting the two baffles 9011. The two baffles 9011 are slidably plugged into the corresponding through holes 602.

[0032] It should be noted that the driving component 902 described in this embodiment has the function of controlling the movement of the pusher plate. The driving component 902 can be a cylinder, a telescopic motor 801, etc. The two baffles 9011 can effectively block the two through holes 602 on the buffer cover 60. After the transfer hole 501 receiving the fly ash block enters the interior of the buffer cover 60, the relevant personnel use the driving component 902 to control the pusher plate structure 901 to move synchronously. During the movement, the pusher plate structure 901 can smoothly push out the fly ash block in the transfer hole 501, successfully completing the unloading operation of the fly ash block. After unloading, the pusher plate structure 901 can also be controlled to move and reset, resealing the through hole 602. This ingenious design allows the transfer hole 501 to quickly re-enter the compression zone 402 to receive fly ash, effectively ensuring the smooth and unobstructed fly ash transfer operation.

[0033] The transfer box 50 is movably disposed through the compression zone 402 via the moving mechanism 70, and multiple transfer holes 501 are arranged side by side inside the transfer box 50. Each transfer hole 501 is open on both the left and right sides, and the transfer hole 501 cooperates with the compression zone 402. The transfer box 50 is slidably disposed within the channel 601 via the moving mechanism 70.

[0034] It should be noted that the moving mechanism 70 described in this embodiment has the function of controlling the reciprocating movement of the transfer box 50. The moving mechanism 70 can be a cylinder, hydraulic cylinder, etc. During the replacement of the transfer hole 501, relevant personnel can control the moving mechanism 70 to extend / retract accordingly, thereby driving the transfer box 50 to move linearly in the forward / reverse direction. This allows multiple transfer holes 501 to enter the compression zone 402 sequentially and repeatedly to receive fly ash, ensuring the smooth progress of the fly ash transfer operation.

[0035] The angle between the two conveying zones 401 is greater than 0 degrees and less than or equal to 180 degrees. The two conveying zones 401 described in this embodiment can convey fly ash to the compression zone 402 in two directions, thereby contributing to the compression effect of the fly ash.

[0036] Specifically, in the actual fly ash collection and treatment operation, personnel first temporarily store the fly ash generated from incineration in the ash hopper 10. Then, the transfer box 50 is moved by the moving mechanism 70, ensuring the corresponding transfer hole 501 accurately enters the compression zone 402. Next, the fly ash in the ash hopper 10 is transported to two feed bins 4011 via the discharge pipe, and the fly ash then enters the corresponding conveying zone 401. In the conveying zone 401, the auger blades 802 perform initial compaction, providing preliminary treatment for the fly ash. Afterwards, the fly ash enters the compression zone 402 for secondary compaction, further enhancing the compression effect.

[0037] As fly ash continuously enters the compression zone 402, it is gradually compacted within the transfer holes 501. Once compaction is complete, personnel again use the moving mechanism 70 to move the transfer box 50, removing the compacted fly ash block from the compression zone 402 and placing it into the corresponding buffer cover 60. Simultaneously, a new transfer hole 501 is installed in the compression zone 402 to continue receiving fly ash. During the replacement of the transfer hole 501, the buffer cover 60 ensures that the compression zone 402 maintains good sealing performance, providing a strong guarantee for continuous and smooth fly ash compression.

[0038] Finally, the relevant personnel controlled the pusher structure 901 to move through the drive component 902, and successfully pushed out the fly ash block in the buffer cover 60, thus completing the unloading operation of the fly ash block. The entire fly ash treatment process was efficient and orderly.

[0039] In summary, the industrial waste incineration fly ash collection and treatment device of this utility model embodiment can continuously compress fly ash without affecting the compression and volume reduction effect of fly ash.
