Description

Technical fields:

[0002] This utility model relates to the field of non-ferrous metal industrial waste treatment technology, specifically to a kiln device for treating non-ferrous metal industrial waste. Background technology:

[0004] The newly generated non-ferrous metal industrial waste slag in my country is rampant, causing serious environmental pollution to soil and groundwater, and urgently needs to be treated. The working process of the kiln equipment for treating non-ferrous metal industrial waste slag is as follows: waste slag crushing, screening, batching, drying, organic matter combustion and decomposition, reduction / oxidation stage, slag formation reaction, and metal sedimentation.

[0005] Existing kiln devices for processing non-ferrous metal industrial waste mainly consist of a kiln feed gate and a feed inlet. When the kiln needs to be fed, the kiln feed gate is opened, and then the dried industrial waste is added into the kiln through the feed inlet for combustion reaction. A large amount of heat and flue gas accumulates in the kiln. Opening the kiln feed gate can easily cause heat and flue gas to flow out from the feed inlet, lowering the temperature inside the kiln and potentially scalding workers, thus prolonging the kiln's processing time for industrial waste. Utility model content:

[0007] Therefore, the purpose of this utility model is to provide a kiln device for processing non-ferrous metal industrial waste to overcome the problems of existing technology. Existing kiln devices for processing non-ferrous metal industrial waste mainly consist of a kiln feed gate and a feed inlet. When feeding is required, the kiln feed gate is opened, and then the dried industrial waste is added to the kiln through the feed inlet for combustion. This results in a large accumulation of heat and flue gas in the kiln. Opening the kiln feed gate easily causes heat and flue gas to escape from the feed inlet, lowering the internal temperature of the kiln and potentially scalding workers, thus prolonging the processing time of the industrial waste.

[0008] This utility model is implemented by the following technical solution:

[0009] A kiln device for processing non-ferrous metal industrial waste includes a kiln body with a feed inlet at one side. A guide cavity is slidably disposed within the feed inlet. Guide grooves are formed on both the top and bottom surfaces of the guide cavity. A baffle is hinged to the guide groove via a rotating shaft. One end of the rotating shaft passes through the guide cavity and into a housing. The rotating shaft is rotatably connected to the guide cavity. A torsion spring is fixedly connected between the rotating shaft and the guide cavity. A toothed ring is fixedly fitted on the bottom rotating shaft. A rack is engaged at the top of the toothed ring. The top of the rack is inserted into and slidably connected to a positioning hole located on the side wall of the top rotating shaft. A guide rod is slidably disposed through the vertical rod of the rack. The guide rod is fixed to the housing. A mechanism for driving the guide cavity to move is fixed to the side wall of the kiln body.

[0010] Preferably, the mechanism for moving the material guide cavity includes an electric push rod fixed to the side wall of the kiln body. The input end of the electric push rod is electrically connected to an external controller, and the output end of the electric push rod is fixedly connected to a connecting rod. The top end of the connecting rod is fixedly connected to the side wall of the material guide cavity.

[0011] Preferably, the longitudinal cross-sectional shape of the baffle is Z-shaped, and the width of the baffle is equal to the width of the guide chute.

[0012] Preferably, the inner bottom surface of the material guiding cavity is an inclined surface, and the inclined surface is inclined downward along the direction of the material guiding groove near the bottom end.

[0013] Preferably, the rack is Z-shaped and the top crossbar near the positioning hole is tapered.

[0014] The advantages of this utility model are as follows: A guide chamber is slidably set at the feed inlet of the kiln body. Baffles are hinged to the top and bottom of the guide chamber through a rotating shaft. The two baffles are alternately opened and closed by an electric push rod, so as to add material to the guide chamber and allow the material in the guide chamber to flow into the kiln body. During this process, the setting of the guide chamber and the baffles prevents the kiln feed inlet from communicating with the outside world, reducing the heat and flue gas flowing out of the kiln feed inlet, ensuring the temperature inside the kiln while preventing the flue gas from burning the workers, and shortening the kiln's processing time for industrial waste.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0027] like Figures 1-4 As shown, this utility model provides the following technical solution: a kiln device for processing non-ferrous metal industrial waste, including a kiln body 1, a feed inlet on the side of the kiln body 1, a guide cavity 2 slidably disposed inside the feed inlet, a guide groove 3 on the top and bottom surfaces of the guide cavity 2, a baffle 5 hinged to the guide groove 3 by a rotating shaft 4, one end of the rotating shaft 4 passing through the guide cavity 2 and into the cover 6, the rotating shaft 4 being rotatably connected to the guide cavity 2, a torsion spring 11 being fixedly connected between the rotating shaft 4 and the guide cavity 2, a toothed ring 7 being fixedly sleeved on the bottom rotating shaft 4, a rack 8 being meshed at the top of the toothed ring 7, the top of the rack 8 being inserted into a positioning hole 9 and slidably connected thereto, the positioning hole 9 being opened on the side wall of the top rotating shaft 4, a guide rod 10 being slidably disposed through the vertical rod of the rack 8, the guide rod 10 being fixed to the cover 6, and a mechanism for driving the guide cavity 2 to move being fixed on the side wall of the kiln body 1.

[0028] The mechanism for driving the material guide chamber 2 to move includes an electric push rod 12 fixed to the side wall of the kiln body 1. The input end of the electric push rod 12 is electrically connected to an external controller, and the output end of the electric push rod 12 is fixedly connected to a connecting rod 13. The top end of the connecting rod 13 is fixedly connected to the side wall of the material guide chamber 2.

[0029] During operation, when feeding is required into the kiln body 1, the controller activates the electric push rod 12. The output end of the electric push rod 12 moves the connecting rod 13, which in turn moves the guide chamber 2. The guide chamber 2, via the rotating shaft 4, moves the baffle 5. As the kiln body 1 moves, it pushes the bottom baffle 5 to rotate, gradually entering the bottom guide trough 3. The bottom baffle 5 rotates the bottom rotating shaft 4, causing the bottom torsion spring 11 to deform. The bottom rotating shaft 4 then rotates the gear ring 7, which in turn moves the rack 8, causing the top crossbar of the rack 8 to gradually slide out of the positioning hole 9, thus removing the pressure on the top rotating shaft 4. The limiting mechanism allows the top rotating shaft 4 to rotate. When the bottom baffle 5 is fully rotated into the guide trough 3, it blocks the guide trough 3. At this time, the top of the toothed ring 7 just slides out of the positioning hole 9. The guide cavity 2 continues to move outward through the output end of the electric push rod 12. When the bottom baffle 5 is in contact with the inner wall of the kiln body 1, the output end of the electric push rod 12 stops working. The top baffle 5 gradually moves and separates from the top surface of the inlet of the kiln body 1. When the top baffle 5 separates from the top surface of the inlet of the kiln body 1, the corresponding torsion spring 11 drives the top rotating shaft 4 to rotate. The rotating shaft 4 drives the baffle 5 fixed to it to rotate. Figure 4 As shown, at this time, the bottom baffle 5 seals the bottom guide chute 3 to prevent the flue gas and heat inside the kiln body 1 from flowing out along the bottom guide chute 3. Then, the staff adds material from the top guide chute 3 into the guide chamber 2.

[0030] After the feed chamber 2 is filled with waste residue, the controller is operated to cause the output end of the electric push rod 12 to gradually retract. The output end of the electric push rod 12 indirectly drives the feed chamber 2 to gradually slide. The kiln body 1 pushes the top baffle 5 to gradually rotate into the feed trough 3 to block it. The top baffle 5 drives the rotating shaft 4 fixed to it to rotate. The rotating shaft 4 drives the positioning hole 9 to rotate and reset. When the top baffle 5 rotates into the feed trough 3, it continues to move with the feed chamber 2. When the bottom baffle 5 slides completely into the kiln body 1 and separates from its surface, the bottom baffle 5 is then... The torsion spring 11 drives the rotating shaft 4, which is fixed to it, to rotate. The rotating shaft 4 drives the bottom baffle 5 to rotate and gradually slide out of the guide trough 3. When the baffle 5 is in contact with the inner wall of the kiln body 1, it stops rotating. The rotating shaft 4 drives the gear ring 7 to rotate. The gear ring 7 drives the rack 8 to move on the guide rod 10, so that the top end of the rack 8 gradually inserts into the positioning hole 9, limiting the rotation of the top end of the rotating shaft 4 so that it cannot rotate. The top end of the rotating shaft 4 cannot rotate, so the baffle 5, which is fixed to it, cannot rotate, thus causing the baffle 5 to be stuck in the top guide trough 3 and block it. Figure 1 As shown, at this time, the waste residue in the feeding chamber 2 flows from the bottom feeding trough 3 along the inner bottom surface of the feeding chamber 2 into the kiln body 1 for combustion.

[0031] The longitudinal cross-sectional shape of the baffle 5 is Z-shaped, and the width of the baffle 5 is equal to the width of the guide trough 3, so that the baffle 5 can cover and seal the guide trough 3.

[0032] The inner bottom surface of the material guiding cavity 2 is inclined, and the inclination direction of the inclined surface is downward along the direction of the material guiding trough 3 near the bottom end. This is designed to facilitate the flow of waste residue in the material guiding cavity 2 along the inner bottom surface of the material guiding cavity 2 and then into the kiln body 1 from the material guiding trough 3 at the bottom end for combustion.

[0033] The rack 8 is Z-shaped and the top crossbar near the positioning hole 9 is tapered, which makes it easy for the top of the rack 8 to be inserted into the positioning hole 9 to limit the rotation shaft 4 at the top.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
