[0002] An ultra-internal combustion waste heat boiler for brick-making tunnel kilns is a device that utilizes the waste heat from the flue gas emitted by the tunnel kiln to produce hot water or steam to meet the heat energy needs of industrial processes. By converting the waste heat in the flue gas into a useful form of heat energy, the boiler achieves energy recovery and reuse. This not only reduces fuel consumption and lowers production costs but also effectively reduces thermal pollution to the environment.

[0003] A waste heat boiler with Chinese patent number CN211011308U includes a main casing, a waste heat boiler body and a control mechanism. The waste heat boiler body includes an upper shell, a steam outlet is fixedly connected to the middle of the upper surface of the upper shell, and a drain outlet is fixedly connected to one side of the upper shell. A spiral rod is provided at one end of the main casing, which effectively ensures the service life of the device.

[0004] During the installation of the waste heat boiler for ultra-internal combustion brick-forming tunnel kilns, a crane is needed to hoist the equipment components to a designated location outside the tunnel kiln. However, due to the large size of the equipment components and the narrow hoisting surface, the hoisting process is not precise and stable, requiring multiple manual interventions for adjustment. This is not conducive to ensuring the installation effect of the boiler. Therefore, a waste heat boiler for ultra-internal combustion brick-forming tunnel kilns with high installation efficiency is needed to solve the above problems.

[0005] To address this, a waste heat boiler for ultra-internal combustion brick-forming tunnel kilns is proposed. Utility Model Content

[0006] In view of this, the present invention provides a waste heat boiler for an ultra-internal combustion brick-forming tunnel kiln to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: A waste heat boiler for an ultra-internal combustion brick-forming tunnel kiln includes a boiler tank. Multiple conveying side pipes are fixedly connected to both ends of the boiler tank. The multiple conveying side pipes are equidistant from each other. A bottom pipe is fixedly connected to the end of the corresponding multiple conveying side pipes away from the boiler tank. Semi-arc hooks are provided on the front and rear sides of the outer end of the bottom pipe. A guide rope is fixedly connected to the lower end of the semi-arc hook. The guide rope is fitted with a matching outer frame. An electric winder is installed on the inner end of the matching outer frame. The guide rope is wound around the outside of the electric winder. The lower end of the matching outer frame contacts the base surface of the top strip brick.

[0008] More preferably, the base surfaces of the two top strip bricks are located directly below the corresponding bottom pipes, and through holes are provided at the upper end of the outer frame.

[0009] More preferably, the guide rope passes through the inside and outside of the through hole, and a hoisting ring is fixedly connected to the upper middle part of the boiler tank.

[0010] More preferably, a connecting rope is attached to the outer end of the hoisting ring, and a crane is connected to the connecting rope.

[0011] More preferably, a transverse slide groove is provided at the lower end of the outer frame, and spring components are fixedly connected to both the front and rear sides of the inner sidewall of the transverse slide groove.

[0012] More preferably, each of the two spring members has a sliding inner block fixedly connected to one end of each other, and a clamping and limiting outer plate fixedly connected to the lower end of the sliding inner block.

[0013] More preferably, the two clamping and limiting outer plates are located on the left and right sides of the top strip brick base surface, respectively, and a tunnel kiln is connected between the two top strip brick base surfaces.

[0014] More preferably, the crane has a built-in control terminal, which is connected to the electric winding device.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] 1. During the hoisting of the boiler silo, this solution utilizes a control terminal to synchronize the lowering speed of the connecting hoisting rope with the winding speed of the guide rope. The guide rope remains taut, and if the boiler silo deviates, the taut guide rope can reset the boiler silo's descent position, limiting and guiding the lower path of the boiler silo to prevent deviation. This eliminates the need for multiple manual interventions and adjustments, ensuring the successful installation of the boiler.

[0017] 2. When the outer frame is positioned above the base surface of the top strip brick, two clamping and limiting plates with locking function can be installed below the outer frame. The two clamping and limiting plates are respectively positioned below the transverse slide groove, and a spring component generates a resisting force on the clamping and limiting plates. The resisting force of the spring component can limit the outer frame to both sides of the base surface of the top strip brick, preventing the outer frame from tilting.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model embodiment provides a waste heat boiler for an ultra-internal combustion brick-forming tunnel kiln, including a boiler tank 2. Multiple conveying side pipes 5 are fixedly connected to both the left and right ends of the boiler tank 2. The multiple conveying side pipes 5 are equidistant from each other. A bottom pipe strip 7 is fixedly connected to the end of the corresponding multiple conveying side pipes 5 away from the boiler tank 2. Semi-arc hooks 6 are provided on the front and rear sides of the outer end of the bottom pipe strip 7. A guide rope 8 is fixedly connected to the lower end of the semi-arc hook 6. The guide rope 8 is fitted with a matching outer frame 9. An electric winder 15 is installed on the inner end of the matching outer frame 9. The guide rope 8 is wound around the outside of the electric winder 15. The lower end of the matching outer frame 9 contacts the top strip brick base surface 1.

[0030] Two top strip brick base surfaces 1 are located directly below the corresponding bottom pipe strips 7. A through hole 12 is provided at the upper end of the outer frame 9. A guide rope 8 passes through the through hole 12. A hoisting ring 3 is fixedly connected to the middle of the upper end of the boiler tank 2. A connecting rope 4 is bound to the outer end of the hoisting ring 3. A crane is connected to the outside of the connecting rope 4. A tunnel kiln is connected between the two top strip brick base surfaces 1. The crane has a built-in control terminal, which is connected to the electric winding device 15.

[0031] Example 2

[0032] In one embodiment, a transverse slide groove 10 is provided at the lower end of the outer frame 9. Spring members 14 are fixedly connected to both the front and rear sides of the inner sidewall of the transverse slide groove 10, and sliding inner blocks 13 are fixedly connected to the ends of the two spring members 14 that are close to each other.

[0033] The lower end of the sliding inner block 13 is fixedly connected to the clamping and limiting outer plate 11, and the two clamping and limiting outer plates 11 are located on the left and right sides of the top strip brick base surface 1, respectively.

[0034] In operation, this invention works as follows: During the hoisting of the boiler tank 2, the two ends of the top strip brick base 1 of the outer frame 9 are respectively set to correspond to the four corner positions below the boiler tank 2. The guide rope 8 in the outer frame 9 is hooked to the designated position of the bottom tube 7 via the semi-circular hook 6. At this time, during the process of the crane lowering the boiler tank 2 using the connecting rope 4, the lowering speed of the connecting rope 4 and the winding speed of the guide rope 8 can be synchronized by the control terminal. The guide rope 8 is in a taut state. Once the boiler tank 2 deviates, the taut guide rope 8 can reset the falling position of the boiler tank 2, so that the guide rope 8 limits and guides the lower path of the boiler tank 2 to prevent it from deviating. This eliminates the need for multiple manual interventions for debugging, ensuring better boiler installation. Furthermore, when the outer frame 9 is positioned above the top strip brick base 1, two clamping and limiting plates 11 with locking functions can be installed below the outer frame 9. These two clamping and limiting plates 11 are respectively positioned below the transverse slide 10, and spring elements 14 generate a resisting force on the clamping and limiting plates 11. This resisting force of the spring elements 14 limits the outer frame 9 to both sides of the top strip brick base 1, preventing the outer frame 9 from tilting. Simultaneously, when the boiler tank 2 is hoisted to its closest position to the top strip brick base 1, workers can remove the outer frame 9 from both sides, allowing the bottom pipe 7 to be smoothly placed above the top strip brick base 1.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
