Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot air furnaces, specifically to a novel hot air furnace suitable for burning waste cloth. Background Technology
[0002] The principle of a hot air furnace is to directly burn fuel, which is then purified to form hot air that directly contacts the material for heating, drying, or baking. This method reduces fuel consumption by about half compared to using steam or other indirect heaters. Therefore, direct high-purity hot air can be used without affecting the quality of the dried product.
[0003] When using waste cloth as fuel, hot air furnaces often suffer from incomplete combustion because the waste cloth is mostly wrapped in strips, making it difficult for the inner layer to come into contact with air. After burning, the chemical fibers and other components of the waste cloth melt and form sticky ash, which easily clumps on the fixed grate, blocking ventilation gaps. This leads to incomplete combustion, reduced efficiency, and even flameout. Furthermore, incompletely burned waste cloth releases a large amount of harmful gases, which is a drawback. Utility Model Content
[0004] (a) Purpose of the utility model
[0005] To address the technical problems existing in the background art, this utility model proposes a novel hot air furnace suitable for burning waste cloth, which has the characteristics of preventing the cloth from melting and clumping and ensuring complete combustion.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, this utility model provides a novel hot air furnace suitable for burning waste cloth, including a hot air furnace, wherein a feeding end seat for feeding is installed on the upper part of the hot air furnace, and an ash discharge end seat for discharging is installed on the lower part.
[0008] The hot air furnace is equipped with an oxygen supply fan on its side wall and an exhaust fan on its top for ventilation. A heat exchanger is installed at the output end of the exhaust fan, and an exhaust end seat is installed at the output end of the heat exchanger.
[0009] The hot air furnace is equipped with a grate inside, and a grid is provided above the grate. The corners of the grid are fixedly installed on each guide rod.
[0010] The first grid plate mechanism includes a first grid plate disposed above the grid, the first grid plate having a built-in first support rod, and a guide ring formed at the corner that moves along the guide rod;
[0011] The second grid plate mechanism includes a second grid plate that moves up and down along the guide rod. The second grid plate is disposed above the first grid plate and has a built-in second support rod.
[0012] The drive mechanism is located outside the first grid plate mechanism and the second grid plate mechanism, and is used to drive the movement of both.
[0013] Preferably, the drive mechanism includes a bracket symmetrically arranged on one side of the guide rod, a screw is provided in the middle of the bracket, and support rods are provided on both sides of the screw. The screw is controlled to rotate by the drive device, and a lead screw slide is sleeved on the outer wall and moves up and down along the support rod. The lead screw slide is connected to the first grid plate through a connecting seat.
[0014] Preferably, the drive mechanism is provided in two sets, and the other set of lead screw slides is connected to the second grid plate through the connecting seat.
[0015] Preferably, the inner diameter of the guide ring is adapted to the outer diameter of the guide rod, and the guide ring moves up and down along the edges of the four guide rods.
[0016] Preferably, the projection between the first support rod and the second support rod is a "cross" structure, and the surfaces of both are in contact with the waste cloth to be burned.
[0017] Preferably, the ash and slag burning in the hot blast stove are transported along the gap between the second grid plate, the first grid plate and the grid, and the bottom of the grate is connected to the ash discharge end seat.
[0018] The above-mentioned technical solution of this utility model has the following beneficial technical effects: the first support rod and the second support rod are arranged in a cross shape. When the two move relative to each other, one rises and the other falls or moves alternately, which loosens the waste cloth left between the two, increases the oxygen contact surface, and allows the waste cloth to burn completely, preventing the formation of large clumps of slag during combustion and solving the problem of incomplete combustion and the release of a large amount of harmful gases. Multiple layers of gaps are formed between the second grid plate, the first grid plate and the grid. By periodically or continuously driving the grid plate to generate relative displacement, the molten material attached to the gaps can be scraped off, the ventilation channel is kept unobstructed, and the oxygen supply is ensured to be uniform.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0026] like Figure 1-4 As shown, the present invention proposes a novel hot air furnace suitable for burning waste cloth, including a hot air furnace 1, with a feeding end seat 11 for feeding material installed on the upper part of the hot air furnace 1, and an ash discharge end seat 12 for discharging material installed on the lower part.
[0027] The hot blast furnace 1 is equipped with an oxygen supply fan 21 on its side wall and an exhaust fan 22 on its top for ventilation. A heat exchanger 23 is installed at the output end of the exhaust fan 22 and an exhaust end seat 24 is installed at the output end of the heat exchanger 23.
[0028] The hot air furnace 1 is equipped with a grate 3 inside, and a grid 4 is set above the grate 3. The corners of the grid 4 are fixedly installed on each guide rod 5.
[0029] The first grid plate mechanism includes a first grid plate 71 disposed above the grid 4, the first grid plate 71 has a built-in first support rod 72, and a guide ring 73 is formed at the corner that moves along the guide rod 5;
[0030] The second grid plate mechanism includes a second grid plate 81 that moves up and down along the guide rod 5. The second grid plate 81 is located above the first grid plate 71 and has a built-in second support rod 82.
[0031] The drive mechanism is located outside the first grid plate mechanism and the second grid plate mechanism, and is used to drive the movement of both.
[0032] It should be noted that the drive mechanism includes a bracket 61 symmetrically arranged on one side of the guide rod 5. A screw 62 is provided in the middle of the bracket 61, and support rods 63 are provided on both sides of the screw 62. The screw 62 is controlled to rotate by the drive device 64, and a lead screw slide 65 that moves up and down along the support rods 63 is sleeved on its outer wall. The lead screw slide 65 is connected to the first grid plate 71 through a connecting seat 66. The drive device 64 drives the screw 62 to rotate, and the threaded transmission provides the power for the lead screw slide 65 to move up and down along the support rods 63, so that the first grid plate 71 connected by the connecting seat 66 can move up and down.
[0033] It should be added that: the drive mechanism is provided in two sets. The other set of lead screw slide 65 is connected to the second grid plate 81 through the connecting seat 66. The first grid plate 71 and the second grid plate 81 are both movable structures, and they move to lift and loosen the waste cloth.
[0034] In this embodiment, the projection between the first support rod 72 and the second support rod 82 is a "cross" structure. The surfaces of both are in contact with the waste cloth to be burned. The first support rod 72 and the second support rod 82 are intersecting in a cross shape. When the two move relative to each other, one rises and the other falls or moves alternately, loosening the waste cloth left between them to prevent it from forming large clumps of slag during combustion. Multiple layers of gaps are formed between the second grid plate 81, the first grid plate 71 and the fixed grid 4. By periodically or continuously displacing these grid plates through the driving mechanism, the molten material attached to the gaps can be scraped off, keeping the ventilation channel unobstructed and ensuring uniform oxygen supply. On the other hand, the tangled waste cloth is improved to an open state, increasing the oxygen contact surface and allowing the waste cloth to burn completely, solving the problem of incomplete combustion and releasing a large amount of harmful gases.
[0035] To ensure the stable up-and-down movement of the first grid plate 71 and the second grid plate 81, the inner diameter of the guide ring 73 is matched with the outer diameter of the guide rod 5, and the guide ring 73 moves up and down along the edges of the four guide rods 5; the drive mechanism provides the power for the movement of the first grid plate 71 and the second grid plate 81, and the corner ends of the guide ring 73 and the guide rod 5 cooperate to ensure their stable displacement.
[0036] To facilitate the discharge and cleaning of waste slag from the burning of waste cloth, the ash slag burning in the hot air furnace 1 is further transported along the gap between the second grid plate 81, the first grid plate 71 and the grid 4. The bottom of the grate 3 is connected to the ash discharge end seat 12. The two sets of drive mechanisms can operate synchronously or alternately, driving the first grid plate 71 and the second grid plate 81 to move up and down, breaking up the slag and clearing the gaps.
[0037] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
