Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fire prevention devices, and in particular to a fire prevention device for the treatment of flammable waste. Background Technology
[0002] With the acceleration of industrialization, the safe disposal of flammable waste has become an increasingly prominent issue. Currently, most of this type of waste is incinerated. For example, some industrial waste residues containing organic matter can be reduced and rendered harmless through incineration, provided that the incineration facilities are well-equipped and pollution control measures are in place.
[0003] However, after such waste is put into the incinerator, existing fire protection designs mostly use a single fireproof valve or isolation structure, which is controlled electrically or manually to isolate the combustion flame to achieve the purpose of fire prevention. But this design has many significant drawbacks: First, single-layer fireproof structures are very prone to failure when faced with high-temperature environments or mechanical failures; second, although some devices have attempted to adopt multi-level fireproof designs, the lack of effective coordination between the various layers makes it difficult to effectively isolate the fire at the moment the waste is put into the incinerator. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this utility model is to propose a fire prevention device for flammable waste treatment, employing a multi-layered fire-resistant structure design. This ensures that when one layer of fire-resistant structure fails due to high-temperature exposure or mechanical malfunction, the remaining layers can continue to function effectively, constructing a robust multi-layered protective barrier. Simultaneously, at the moment the waste is fed into the incinerator, each layer of fire-resistant mechanism can operate in an orderly manner, precisely blocking the spread of fire and effectively ensuring the safety of the incineration process.
[0005] To achieve the above objectives, this utility model proposes a fire prevention device for flammable waste treatment, comprising a fireproof box, a fireproof pipe, a first fireproof mechanism, a second fireproof mechanism, and a drive assembly. The fireproof pipe is vertically mounted on the fireproof box and communicates with it; a feed hopper is located at the top of the fireproof pipe. The first fireproof mechanism and the second fireproof mechanism are longitudinally arranged side-by-side and rotatably mounted within the fireproof pipe, with the first fireproof mechanism positioned above the second fireproof mechanism. The drive assembly is mounted on the fireproof pipe and connected to the second fireproof mechanism.
[0006] This utility model of a fire prevention device for flammable waste treatment adopts a multi-layer fireproof structure design, which ensures that when a certain layer of fireproof structure fails due to high temperature exposure or mechanical failure, the other layers can still continue to play an effective role, forming a solid multi-layer protective barrier; at the same time, at the moment the waste is put into the incinerator, the fire prevention mechanisms of each layer can operate in an orderly manner, accurately blocking the spread of fire and effectively ensuring the safety of the incineration process.
[0007] In addition, the fire prevention device for flammable waste treatment proposed in the application may also have the following additional technical features:
[0008] Specifically, the first fireproof mechanism includes a first support shaft, two first fireproof plates, and two sets of torsion springs. The first support shaft is horizontally fixed inside the fireproof pipe. The two first fireproof plates are symmetrically distributed inside the fireproof pipe, and the opposite surfaces of the two first fireproof plates are respectively sleeved on the first support shaft by collars. The two sets of torsion springs are respectively sleeved on the first support shaft, and one end of the two sets of torsion springs is fixedly connected to the first support shaft, and the other end of the two sets of torsion springs is fixedly connected to the corresponding collars.
[0009] Specifically, the second fireproof mechanism includes a second support shaft, a second fireproof plate, a third fireproof plate, and a connecting pipe. The second support shaft is horizontally and rotatably disposed within the fireproof pipe, with one end extending through the fireproof pipe and fixedly connected to an end plate. A first drive rod is vertically disposed on the end plate. The second fireproof plate is fixedly attached to the second support shaft via a sleeve. The third fireproof plate is symmetrically disposed with the second fireproof plate and is sleeved onto the second support shaft via a sleeve. The connecting pipe is sleeved onto the second support shaft, with one end fixedly connected to the third fireproof plate and the other end movably extending through the fireproof pipe and fixedly connected to a support ring. A second drive rod is vertically disposed on the support ring.
[0010] Specifically, the drive assembly includes a support frame, a U-shaped frame, and a telescopic mechanism. The support frame is fixedly mounted on the outer wall of the fireproof pipe. The U-shaped frame is movably mounted within the support frame, and each of the two side walls of the U-shaped frame has a sliding groove, which is slidably connected to the corresponding first drive rod and second drive rod, respectively. The telescopic mechanism is fixedly mounted on the fireproof box, and the output end of the telescopic mechanism movably passes through the support frame and is detachably connected to the U-shaped frame.

Detailed Implementation
[0018] The embodiments of the present invention are described in detail below, examples of which 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 the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0019] The following description, in conjunction with the accompanying drawings, describes a fire prevention device for flammable waste treatment according to an embodiment of the present invention.
[0020] like Figures 1-4 As shown, the fire prevention device for flammable waste treatment in this embodiment of the present invention may include a fireproof box 10, a fireproof pipe 20, a first fireproof mechanism 30, a second fireproof mechanism 40, and a drive assembly 50.
[0021] The fireproof box 10 is fixedly installed on the incinerator (not shown in the figure) and communicates with the inner cavity of the incinerator. The fireproof pipe 20 is vertically installed on the fireproof box 10 and communicates with the fireproof box 10. The top of the fireproof pipe 20 is provided with a feed hopper 21.
[0022] The first fireproof mechanism 30 and the second fireproof mechanism 40 are arranged longitudinally side by side and rotated inside the fireproof pipe 20, with the first fireproof mechanism 30 located above the second fireproof mechanism 40. The drive component 50 is arranged on the fireproof pipe 20 and connected to the second fireproof mechanism 40. The drive component 50 is used to drive the second fireproof mechanism 40 to control the opening and closing of the outlet of the fireproof pipe 20.
[0023] To clearly illustrate the previous embodiment, in one embodiment of this utility model, as follows: Figure 2 and Figure 3 As shown, the first fireproof mechanism 30 may include a first support shaft 31, two first fireproof plates 32 and two torsion springs 33.
[0024] In this embodiment, the first support shaft 31 is horizontally fixed inside the fireproof pipe 20, and two first fireproof plates 32 are symmetrically distributed inside the fireproof pipe 20. The opposite surfaces of the two first fireproof plates 32 are respectively fitted onto the first support shaft 31 through collars 301. It should be noted that the first fireproof plate 32 described in this embodiment can be made of ceramic fiber board with excellent fire resistance or other new fireproof materials, and the surface can be coated with a high-temperature resistant and corrosion-resistant coating to enhance its fire resistance and durability.
[0025] Two sets of torsion springs 33 are respectively sleeved on the first support shaft 31, and one end of the two sets of torsion springs 33 is fixedly connected to the first support shaft 31, and the other end of the two sets of torsion springs 33 is fixedly connected to the corresponding collar 301. Each set of torsion springs 33 includes two torsion springs 33 arranged symmetrically.
[0026] It should be noted that the elastic coefficient of the torsion spring 33 described in this embodiment has been precisely calculated and tested, and can keep the two first fireproof plates 32 in a closed state under normal circumstances. When a certain impact force is applied to the first fireproof plate 32 (such as the impact when waste is thrown in), the first fireproof plate 32 can quickly return to a closed state under the action of the torsion spring 33, effectively blocking the flames and hot air from rising.
[0027] Furthermore, in one embodiment of this utility model, such as Figure 4 As shown, the second fireproof mechanism 40 may include a second support shaft 41, a second fireproof plate 42, a third fireproof plate 43, and a connecting pipe 44.
[0028] The second support shaft 41 is horizontally and rotatably installed inside the fireproof pipe 20, and one end of the second support shaft 41 extends through the fireproof pipe 20 and is fixedly connected to the end plate 401. The end plate 401 is vertically provided with a first drive rod 402.
[0029] The second fireproof board 42 is fixed to the second support shaft 41 by a sleeve, and the third fireproof board 43 is symmetrically arranged with the second fireproof board 42 and is sleeved on the second support shaft 41 by a sleeve.
[0030] It should be noted that the second fireproof board 42 and the third fireproof board 43 described in this embodiment can both be made of the same or similar fireproof materials as the first fireproof board 32. The second fireproof board 42 and the third fireproof board 43 are designed with reasonable shape and size, and can completely cover the cross-section of the fireproof pipe 20 when closed, effectively preventing the passage of flames.
[0031] The connecting pipe 44 is sleeved on the second support shaft 41, and one end of the connecting pipe 44 is fixedly connected to the third fireproof plate 43. The other end of the connecting pipe 44 movably passes through the fireproof pipe 20 and is fixedly connected to the support ring 403. The support ring 403 is vertically provided with a second drive rod 404.
[0032] Furthermore, in one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the drive assembly 50 may include a support frame 51, a U-shaped frame 52 and a telescopic mechanism 53, wherein the support frame 51 is fixedly installed on the outer wall of the fireproof pipe 20.
[0033] The U-shaped frame 52 is movably disposed within the support frame 51, and sliding grooves 501 are respectively provided on the two side walls of the U-shaped frame 52. The two sliding grooves 501 are slidably connected to the corresponding first drive rod 402 and second drive rod 404. The telescopic mechanism 53 is fixedly disposed on the fireproof box 10, and the output end of the telescopic mechanism 53 movably passes through the support frame 51 and is detachably connected to the U-shaped frame 52. It can be understood that the output end of the telescopic mechanism 53 described in this embodiment is detachably connected to the U-shaped frame 52, which facilitates the installation and replacement of the telescopic mechanism 53. For example, the telescopic mechanism 53 can be connected to the U-shaped frame 52 by a pin or threaded fastener (screw, bolt, or bolt).
[0034] It should be noted that the telescopic mechanism 53 described in this embodiment can be a cylinder, a hydraulic cylinder, or an electric telescopic rod.
[0035] Specifically, in the initial state, the two first fireproof plates 32 of the first fireproof mechanism 30 are in a closed state under the action of the torsion spring 33, sealing the upper space of the fireproof pipe 20. The second fireproof plate 42 and the third fireproof plate 43 of the second fireproof mechanism 40 are also in a closed position, blocking the lower part of the fireproof pipe 20 from communicating with the fireproof box 10.
[0036] When flammable waste needs to be incinerated in the incinerator, the relevant personnel first need to put the flammable waste into the feed hopper 21. The flammable waste entering the feed hopper 21 falls directly onto the two first fireproof plates 32 of the first fireproof mechanism 30. When the weight of the flammable waste exceeds the torque of the torsion spring 33, the two first fireproof plates 32 open under the weight of the flammable waste. At this time, the flammable waste falls onto the second fireproof plate 42 and the third fireproof plate 43 of the second fireproof mechanism 40. The two first fireproof plates 32, which have lost pressure, reset under the reverse torque of the torsion spring 33, sealing the upper space of the fireproof pipe 20, thereby preventing the flame from spreading further upward and ensuring the reliability and safety of the fireproof device.
[0037] Subsequently, the operator can control the telescopic mechanism 53 to start, and its output end extends to push the U-shaped frame 52 upward within the support frame 51. The U-shaped frame 52 drives the first drive rod 402 and the second drive rod 404 to move through the slide groove 501, thereby causing the second support shaft 41 and the connecting pipe 44 to rotate. The second fireproof plate 42 and the third fireproof plate 43 are then driven to open, and the waste falls into the fireproof box 10 through the feed hopper 21 and the fireproof pipe 20, and then enters the incinerator for incineration.
[0038] Once the waste enters the incinerator, the staff controls the telescopic mechanism 53 to drive the U-shaped frame 52 to reset and move, thereby controlling the second fireproof plate 42 and the third fireproof plate 43 to reset and rotate, and sealing the fireproof pipe 20 to form a secondary protection.
[0039] In summary, the fire prevention device for flammable waste treatment in this embodiment of the utility model adopts a multi-layer fireproof structure design, which ensures that when a certain layer of fireproof structure fails due to high temperature exposure or mechanical failure, the other layers can still continue to function effectively, forming a solid multi-layer protective barrier; at the same time, at the moment the waste is put into the incinerator, the fire prevention mechanisms of each layer can operate in an orderly manner, accurately blocking the spread of fire and effectively ensuring the safety of the incineration process.
