Description
Technical Field
[0001] This invention relates to the field of kiln technology, specifically a kiln waste heat recovery and reuse device. Background Technology
[0002] The waste heat recovery and reuse device for kilns is a device used to extract heat energy from the waste flue gas emitted by industrial kilns. Its main purpose is to save energy and reduce environmental pollution. It can help industrial enterprises improve thermal efficiency, reduce energy costs, and achieve the goal of energy conservation and emission reduction.
[0003] A search revealed that Chinese patent number CN212538898U discloses a kiln flue gas waste heat recovery and reuse device, comprising a waste heat recovery chamber, a flue gas exhaust chamber at the top of the waste heat recovery chamber with a flue gas outlet at the top, and a flue gas inlet chamber at the bottom with a flue gas inlet at the bottom. Inside the waste heat recovery chamber, a water pipe is arranged in a serpentine pattern from bottom to top, with its top end extending through the upper outer wall and its bottom end extending through the lower outer wall. In this kiln flue gas waste heat recovery and reuse device, high-temperature flue gas heats the cold water in the water pipe after passing through it, raising the water temperature. The hot water is then discharged from the top of the water pipe for use. Low-temperature flue gas is purified by an impurity cleaning mechanism, removing impurities before being discharged from the top flue gas outlet.
[0004] However, existing technologies have the following shortcomings:
[0005] In actual use, existing kiln waste heat recovery units are equipped with dust collection bins to collect impurities filtered out. However, when moving the collection frame inside the dust collection bin, the dust inside the collection frame will float into the interior of the kiln waste heat recovery unit, thus increasing the workload of cleaning the kiln waste heat recovery unit. Summary of the Invention
[0006] The purpose of this invention is to address the problem that existing kiln waste heat recovery devices, which are equipped with dust collection bins to collect filtered impurities, experience dust accumulation inside the collection frame during transport, which increases the workload of cleaning the kiln waste heat recovery device. This invention provides a kiln waste heat recovery and reuse device.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] This invention relates to a device for recovering and reusing waste heat from kilns, comprising:
[0009] The main components include the kiln waste heat recovery unit body and the cabinet door;
[0010] The cabinet has eight sets of doors, which are hinged to one side of the main body of the kiln waste heat recovery unit.
[0011] A shielding component, comprising a movable groove, pulleys, a connecting frame, and an elastic cloth;
[0012] The movable groove is provided in two sets, and the pulleys are slidably connected to the inside of any one set of the movable groove. There are a total of ten sets of pulleys, which are distributed in five-fives inside the movable groove. The connecting frame is fixed on the upper surface of any one set of pulleys, and the elastic cloth is sewn on the outer surface of the connecting frame. One end of each pulley is fixed inside the movable groove.
[0013] The main body of the kiln waste heat recovery unit is used to process the exhaust heat. Opening the cabinet door makes it easy to inspect the internal environment of the kiln waste heat recovery unit. The moving groove is used for the pulley to move inside. The sliding mechanism is used to drive the connecting frame to move synchronously. The connecting frame is used to support and install the elastic cloth. The elastic cloth is used to seal the environment on top of the storage frame to prevent dust from floating inside the kiln waste heat recovery unit.
[0014] As a further embodiment of the present invention: limit grooves are provided at both ends of the top of any set of moving grooves, and limit blocks are fixed on the outer surfaces of both ends of the pulley, with the limit blocks located inside the limit grooves.
[0015] By setting a limiting groove, the limiting block can move within it, and the limiting block drives the pulley to make a stable horizontal movement.
[0016] As a further embodiment of the present invention, it also includes a movable component, which includes a mounting groove, a mounting hole, a first spring, and a movable frame;
[0017] The mounting slots are located inside the bottom of the main body of the kiln waste heat recovery unit. There are four sets of mounting slots. The mounting holes are located inside the bottom of the main body of the kiln waste heat recovery unit. The four sets of mounting holes are symmetrically arranged inside any set of mounting slots. The first spring is fixed inside any set of mounting holes. The movable frame is fixed to the upper surface of the first spring.
[0018] The installation slot is provided for the movable frame to move inside, and the installation hole is used to support the first spring. The first spring is used to drive the movable frame to move up and down, and the storage frame is placed inside the movable frame.
[0019] As a further embodiment of the present invention: a storage frame is movably connected inside the movable frame, and a moving slot and a limiting slot are formed at both ends of the top of the storage frame.
[0020] Dust is collected and stored using a designated storage box, and a pulley is installed to support it.
[0021] As a further embodiment of the present invention, it also includes a connector;
[0022] The connector includes a fixed post, a connecting post, and a limiting plate;
[0023] The fixing column is fixed to the upper surface of the middle part of the connecting frame on one side, the connecting column is fixed to the upper surface of the fixing column, and the limiting plate is threaded to the outer surface of the top of the connecting column.
[0024] The connecting column is supported and installed by the fixed column, and the limiting plate is used to limit the fixed frame to the outer surface of the connecting column.
[0025] As a further embodiment of the present invention: a fixing frame is sleeved on the outer surface of the connecting column, and a rotating column is rotatably connected to one side of the fixing frame.
[0026] By setting up a fixed frame to support and install the rotating column, the rotating column can rotate inside the connecting column.
[0027] As a further embodiment of the present invention: a connecting rod is fixed to the lower surface of one side of the rotating column, a square block is fixed to the lower surface of the connecting rod, and a limit frame is fixed to the outer surface of the other side of the bottom cabinet door.
[0028] The rotating column is supported and installed by the connecting rod, which in turn supports and installs the square block. When the square block moves into the limit frame, pulling the cabinet door will cause the connecting rod to move outward synchronously.
[0029] As a further embodiment of the present invention, it also includes a locking element;
[0030] The locking component includes a mounting block, a limiting bracket, and a fixing frame;
[0031] The mounting block is fixed to the upper surface of the pulley on one side, the limiting frame is fixed to the outer surface of the mounting block on one side, and the fixing frame is fixed to the outer surface of the top side of the storage frame.
[0032] The pulley is supported and installed by setting up the mounting block, which in turn supports and installs the limit frame, while the fixed frame is used to support and install the fixed pipe.
[0033] As a further embodiment of the present invention: a fixing tube is fixed to the outer surface of the other side of the fixing frame, and a second spring is fixed to the inner surface of the fixing tube in a circumferential array.
[0034] The limiting frame is moved into the fixed tube by the fixed tube, so that the elastic cloth is fully unfolded. The second spring is used to deform the movable block, thereby limiting the limiting frame into the fixed tube.
[0035] As a further embodiment of the present invention: a movable block is fixed on the inner surface of the second spring, and the diameter of the circular hole formed inside the movable block is smaller than the diameter of the ball on the limiting frame.
[0036] The movable block is used to limit the position of the limit frame, so that the elastic fabric remains in an unfolded state.
[0037] Compared with the prior art, the beneficial effects of the present invention are:
[0038] With the installation of the shielding components, when one side of the connecting frame is subjected to force, the pulley will move in the moving groove. With the cooperation of the limiting groove and the limiting block, the connecting frame moves smoothly to one side, thereby fully unfolding the elastic cloth and keeping the top of the storage frame closed. This solution ensures that the top of the storage frame is covered when the storage frame is moved, preventing dust from falling into the interior of the kiln waste heat recovery unit and reducing the amount of cleaning work.
[0039] Based on the first beneficial effect, when dust falls into the storage frame, the first spring deforms as the weight inside the storage frame increases, and the movable frame continuously retracts into the mounting slot. At the same time, the linkage fixing frame moves down synchronously, thereby moving the linkage square block down into the limiting frame. When the cabinet door is opened, the rotating column is pulled outward, which drives the fixing frame to stretch to one side, thereby moving the linkage pulley to one side. This solution can quickly cover the top of the storage frame when the cabinet door is opened without manually pushing the connecting frame, thus improving the efficiency of cleaning the storage frame.
[0040] Based on the second beneficial effect, when the pulley moves to one side of the moving groove, the linkage limit frame moves to one side of the moving groove, and the limit frame will pass through the movable block. When the limit frame passes through the movable block, the second spring deforms, causing the limit frame to move to one side of the fixed tube, thereby limiting the limit frame inside the fixed tube. This solution avoids the situation where the pulley is displaced during the handling of the storage frame, causing the connecting frame to shift to the other side and resulting in dust scattering.

[0049] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0050] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 In this embodiment of the invention, a kiln waste heat recovery and reuse device includes: a main body 1, which includes a kiln waste heat recovery unit body 11 and a cabinet door 12;
[0051] The cabinet door 12 is provided in eight sets, and the cabinet door 12 is hinged to one side of the main body 11 of the kiln waste heat recovery unit.
[0052] The shielding component 3 includes a movable groove 31, a pulley 33, a connecting frame 35, and an elastic cloth 36;
[0053] The movable groove 31 is provided in two sets. The pulleys 33 are slidably connected to the inside of any one set of movable grooves 31. There are ten sets of pulleys 33, which are distributed in five-fives inside the movable grooves 31. The connecting frame 35 is fixed to the upper surface of any one set of pulleys 33. The elastic cloth 36 is sewn to the outer surface of the connecting frame 35. Limiting grooves 32 are opened at both ends of the top of any one set of movable grooves 31. Limiting blocks 34 are fixed to the outer surfaces of both ends of the pulleys 33. The limiting blocks 34 are located inside the limiting grooves 32.
[0054] In this embodiment: when one side of the connecting frame 35 is subjected to force, the pulley 33 will move inside the moving groove 31, and with the cooperation of the limiting groove 32 and the limiting block 34, the connecting frame 35 moves smoothly to one side, thereby fully unfolding the elastic cloth 36, so that the top of the storage frame 25 is in a closed state; in this step, when the storage frame 25 is transported, the top of the storage frame 25 is wrapped up to prevent dust from falling into the interior of the kiln waste heat recovery unit body 11, which increases the workload of cleaning.
[0055] Please refer to this carefully. Figures 1 to 3 , Figure 6 It also includes a movable component 2, which includes a mounting groove 21, a mounting hole 22, a first spring 23, and a movable frame 24;
[0056] The mounting slot 21 is located inside the bottom of the main body 11 of the kiln waste heat recovery unit. There are four sets of mounting slots 21. The mounting holes 22 are located inside the bottom of the main body 11 of the kiln waste heat recovery unit. Four sets of mounting holes 22 are symmetrically arranged inside any set of mounting slots 21. The first spring 23 is fixed inside any set of mounting holes 22. The movable frame 24 is fixed on the upper surface of the first spring 23. The pulley 33 on the other side is fixed inside the movable slot 31.
[0057] The storage frame 25 is movably connected inside the movable frame 24. The moving slot 31 and the limiting slot 32 are opened at both ends of the top of the storage frame 25.
[0058] It also includes connector 4;
[0059] The connector 4 includes a fixing post 41, a connecting post 42, and a limiting plate 43;
[0060] Among them, the fixing post 41 is fixed on the upper surface of the middle part of the connecting frame 35 on one side, the connecting post 42 is fixed on the upper surface of the fixing post 41, and the limiting plate 43 is threaded to the outer surface of the top of the connecting post 42.
[0061] A fixing frame 44 is sleeved on the outer surface of the connecting column 42, and a rotating column 45 is rotatably connected to one side of the fixing frame 44.
[0062] A connecting rod 46 is fixed to the lower surface of one side of the rotating column 45, and a square block 47 is fixed to the lower surface of the connecting rod 46. A limit frame 48 is fixed to the outer surface of the other side of the bottom cabinet door 12.
[0063] In this embodiment: when dust falls into the storage frame 25, the weight inside the storage frame 25 increases continuously, causing the first spring 23 to deform and the movable frame 24 to continuously retract into the mounting groove 21. At the same time, the linkage fixing frame 44 moves down synchronously, thereby causing the linkage square block 47 to move down into the limiting frame 48. When the cabinet door 12 is opened, the rotating column 45 is pulled outward, which drives the fixing frame 44 to stretch to one side, thereby causing the linkage pulley 33 to move to one side. After the cabinet door 12 is opened, the limiting plate 43 is removed from the connecting column 42, and an upward force is applied to the fixing frame 44, so that the fixing frame 44 is detached from the outside of the connecting column 42.
[0064] This step allows the top of the storage box 25 to be quickly covered when the cabinet door 12 is opened, without the need to manually push the connecting bracket 35, thereby improving the efficiency of cleaning the storage box 25.
[0065] Please refer to this carefully. Figures 5 to 7 It also includes locking component 5;
[0066] Locking component 5 includes mounting block 51, limit bracket 52, and fixing frame 53;
[0067] Among them, the mounting block 51 is fixed to the upper surface of the pulley 33 on one side, the limiting frame 52 is fixed to the outer surface of the mounting block 51 on one side, and the fixing frame 53 is fixed to the outer surface of the top side of the storage frame 25.
[0068] A fixing tube 54 is fixed to the outer surface of the other side of the fixing frame 53, and a second spring 55 is fixed to the inner surface of the fixing tube 54 in a circumferential array.
[0069] A movable block 56 is fixed to the inner surface of the second spring 55, and the diameter of the circular hole formed inside the movable block 56 is smaller than the diameter of the ball on the limit frame 52.
[0070] In this embodiment: when the pulley 33 moves to one side of the moving groove 31, the linkage limiting frame 52 moves to one side of the moving groove 31, and the limiting frame 52 will pass through the middle of the movable block 56. When the limiting frame 52 passes through the movable block 56, the second spring 55 deforms, causing the limiting frame 52 to move to one side of the fixed tube 54, thereby limiting the limiting frame 52 in the fixed tube 54.
[0071] This step prevents the pulleys 33 from shifting during the handling of the storage box 25, causing the connecting frame 35 to deviate to the other side and resulting in dust scattering.
[0072] Working principle:
[0073] When dust settles inside the storage frame 25, the weight inside the storage frame 25 increases, causing the first spring 23 to deform. The movable frame 24 continuously retracts into the mounting groove 21. Simultaneously, the linkage fixing bracket 44 moves downward, causing the linkage square block 47 to move downward into the limiting frame 48. When the cabinet door 12 is opened, the rotating column 45 is pulled outward, causing the fixing bracket 44 to stretch to one side. This causes the linkage pulley 33 to move to one side, and the pulley 33 moves inside the moving groove 31. With the cooperation of the limiting groove 32 and the limiting block 34, the connecting frame 35 moves smoothly to one side, thus completely securing the elastic cloth 36. The top of the storage frame 25 is closed when the pulley 33 moves to one side of the moving groove 31. The linkage limit frame 52 moves to one side of the moving groove 31 and passes through the middle of the movable block 56. When the limit frame 52 passes through the movable block 56, the second spring 55 deforms, causing the limit frame 52 to move to one side of the fixed tube 54, thereby limiting the limit frame 52 inside the fixed tube 54. After opening the cabinet door 12, the limit plate 43 is removed from the connecting column 42, and an upward force is applied to the fixed frame 44, causing the fixed frame 44 to detach from the outside of the connecting column 42. The storage frame 25 can then be moved out of the movable frame 24.
[0074] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
