Description

Technical Field

[0001] This utility model relates to the field of roasting furnace technology, and specifically to a roasting furnace. Background Technology

[0002] A calcining furnace, as a high-temperature processing device, is mainly used to complete a certain chemical reaction or heat treatment process under conditions below the melting temperature of the material. It is an important component of furnace charge preparation and is widely used in smelting, carbon product manufacturing, and other fields.

[0003] In related technologies, to ensure uniform heating inside the roasting furnace, an inclined rotary kiln roasting furnace body is used. The furnace body is equipped with lifting plates. Most roasting furnace heating devices involve installing a combustion chamber on the outside of the furnace body, and heating the bottom of the furnace body through a burner located at the bottom of the combustion chamber. The material lifted by the lifting plates continuously contacts the bottom of the furnace body, thereby achieving uniform heating of the material. Finally, the inclined angle of the rotary kiln causes the roasted material to move towards the discharge end of the rotary kiln roasting furnace.

[0004] However, most of the existing rotary kiln roasting furnaces have equipment supports at a constant angle. When it is necessary to adjust the inclination angle inside the roasting furnace, special tools are required to lower the height of the equipment supports, which makes the angle adjustment inconvenient. There are also certain safety risks when operators use tools to adjust the angle. In order to solve the above problems, a roasting furnace is proposed. Utility Model Content

[0005] In view of this, the present invention provides a roasting furnace. The present invention uses a lifting device to raise the front of the rotary kiln roasting furnace upwards. At the same time, the angle adjustment component will lift the front of the rotary kiln roasting furnace along with the lifting device, causing the rear end of the rotary kiln roasting furnace to change angle. This adjusts the angle of the rotary kiln roasting furnace towards the discharge end, achieving the purpose of adjusting the angle of the rotary kiln roasting furnace. The support component provides support when the angle of the adjustment bracket changes, thereby reducing the load on the adjustment bracket and enabling the rotary kiln roasting furnace to be stably adjusted.

[0006] To solve the above-mentioned technical problems, this utility model provides a roasting furnace, including a quantitative conveyor at the feed end of the rotary kiln roasting furnace, a heating chamber at the bottom of the furnace body, a motor support at the bottom of the drive gear on the rotary kiln roasting furnace, a first support at the bottom of the quantitative conveyor, the heating chamber at the same height as the bottom of the first support, the motor support at the same height as the first support, an adjusting support at the bottom of the heating chamber, a lifting device at the bottom front end of the adjusting support, a supporting component at the middle of the lower surface of the adjusting support, and an angle adjusting component at the bottom rear end of the adjusting support.

[0007] The angle adjustment assembly includes an adjustment block fixed to the lower surface of the adjustment bracket. The adjustment block is used to connect the lower surface of the adjustment bracket to the rotating shaft. A rotating shaft is rotatably installed axially inside the adjustment block. The rotating shaft is used to drive the rear end of the adjustment bracket to rotate. A bearing seat is provided at each of the left and right ends of the rotating shaft. The bearing seat is used to fix the rotating shaft and prevent it from falling off. A rotating cavity is provided between the bearing seats. The rotating cavity prevents the adjustment block driven synchronously by the rotating shaft from colliding with the equipment base plate when the rotating shaft rotates. A pad is provided at the bottom of each bearing seat. The pad is used to increase the height of the bearing seat.

[0008] The support components include an adjustment plate fixed to the lower surface of the adjustment bracket. The adjustment plate connects the lower surface of the adjustment bracket to the tilting knuckle. Multiple tilting knuckles are provided on the lower surface of the adjustment plate. The tilting knuckles are used to connect with the telescopic support rod when the angle of the adjustment bracket changes, thereby preventing the telescopic support rod from breaking. Each tilting knuckle has a telescopic support rod at its bottom. The telescopic support rod is used to support the adjustment bracket when it is lifted by the hydraulic lifting rod. Each telescopic support rod has a positioning block at its bottom, which is used to connect the bottom of the telescopic support rod to the equipment base plate.

[0009] The lifting device includes a connecting plate fixed to the lower surface of the adjusting bracket. The connecting plate is used to fix the lower surface of the adjusting bracket to the connecting block. Multiple connecting blocks are provided on the lower surface of the connecting plate. The connecting blocks are used to connect the connecting plate to the telescopic end of the hydraulic lifting rod. A hydraulic lifting rod is provided at the bottom of each connecting block. The hydraulic lifting rod is used to drive the front end of the adjusting bracket to rise and fall, thereby driving the front end of the roasting furnace to rise and fall.

[0010] The bottom of the drive end of the hydraulic lifting rod is at the same height as the bottom of the positioning block, and the bottom of the positioning block is at the same height as the bottom of the pad block. The bottom of the positioning block is provided with an equipment base plate, which is used to fix the positioning block, the drive end of the hydraulic lifting rod, and the pad block.

[0011] A compression packing seal ring is provided at both the front and rear ends of the heating chamber. The compression packing seal ring is used to seal the connection gap between the heating chamber and the rotary kiln calcining drum, thereby reducing the heat dissipation rate of the heating chamber.

[0012] The feed inlet of the quantitative conveyor is equipped with a discharge pipe, which connects the quantitative conveyor to the discharge hopper. The top of the discharge pipe is connected to the discharge hopper, which is used to feed the material to be roasted. A level gauge is installed at the bottom of the discharge hopper to detect the material level. When the material level is low, the feeding automatically stops and a seal is formed by the material to prevent air from entering the roasting furnace through the discharge pipe. An electric valve is installed in the middle section of the discharge pipe to open and close the discharge pipe. The electric valve is also used to seal the feed end of the rotary kiln roasting furnace.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The adjustable bracket is connected and fixed to various components of the rotary kiln roasting furnace. The lifting device raises the front of the rotary kiln roasting furnace, and the angle adjustment component raises the front of the rotary kiln roasting furnace along with the lifting device, causing the rear of the rotary kiln roasting furnace to change angle. This adjusts the angle of the rotary kiln roasting furnace towards the discharge end, achieving the purpose of adjusting the angle of the rotary kiln roasting furnace. The support component provides support when the adjustable bracket changes angle, thereby reducing the load on the adjustable bracket and enabling the rotary kiln roasting furnace to be adjusted stably.

[0014] 2. The sealing of the connection gap between the heating chamber and the rotary kiln drum is achieved by tightening the packing seal ring, thereby reducing the heat dissipation rate of the heating chamber. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0018] like Figure 1-4 As shown: This embodiment provides a roasting furnace, including a quantitative conveyor 101 installed at the feed end of a rotary kiln roasting furnace 100, which supplies drying materials to the rotary kiln roasting furnace 100; a heating chamber 102 installed at the bottom of the furnace body of the rotary kiln roasting furnace 100, which heats and maintains the furnace body of the rotary kiln roasting furnace 100; and a motor bracket 103 at the bottom of the drive gear on the rotary kiln roasting furnace 100, which supports the rotary kiln roasting furnace 100. The rotary kiln calcining furnace 100 has a drive gear and a first support 104 at its bottom. The first support 104 is used to support and fix the rotary kiln calcining furnace 100. The heating chamber 102 is at the same height as the bottom of the first support 104. The first support 104 and the adjusting support 105 can be fixed by bolts or welding. The bottom of the heating chamber 102 and the adjusting support 105 can be fixed by bolts or welding. The motor support 103 is at the same height as the first support 104. The motor support 103 and the adjusting support 105 can be fixed by bolts or welding, so that the bottom height of the entire rotary kiln calcining furnace 100 is uniform. The lower part of the heating chamber 102 is provided with an adjusting support 105, which is used to support the rotary kiln calcining furnace 100 and its components. The front bottom of the adjusting support 105 is provided with a lifting device 200, which is used to lift the front end of the adjusting support 105, thereby raising the front of the rotary kiln calcining furnace 100. By cooperating with the angle adjustment component 400, the tilt angle of the rotary kiln calcining furnace 100 can be adjusted. The purpose is to provide a support component 300 at the center of the lower surface of the adjusting bracket 105. The support component 300 is used to provide support when the angle of the adjusting bracket 105 changes, thereby reducing the load on the adjusting bracket 105. An angle adjustment component 400 is provided at the bottom of the rear end of the adjusting bracket 105. The angle adjustment component 400 is used to lift the front end of the rotary kiln calciner 100 along with the lifting device 200, thereby causing the rear end of the rotary kiln calciner 100 to change angle, thereby adjusting the tilt angle of the rotary kiln calciner 100.

[0019] In use, the adjusting bracket 105 is connected and fixed to various components on the rotary kiln calciner 100. The lifting device 200 lifts the front end of the adjusting bracket 105, thereby raising the front of the rotary kiln calciner 100. At the same time, the angle adjusting component 400 will lift the front end of the rotary kiln calciner 100 along with the lifting device 200, thereby changing the angle of the rear end of the rotary kiln calciner 100. This adjusts the tilt angle of the rotary kiln calciner 100 towards the discharge end, achieving the purpose of adjusting the tilt angle of the rotary kiln calciner 100. The supporting component 300 provides support when the adjusting bracket 105 changes angle, thereby reducing the load on the adjusting bracket 105 and allowing the rotary kiln calciner 100 to be adjusted stably.

[0020] This embodiment provides a roasting furnace. like Figure 1 , 3 As shown: The angle adjustment assembly 400 includes an adjustment block 401 fixed to the lower surface of the adjustment bracket 105. The adjustment bracket 105 and the adjustment block 401 can be welded or bolted together. The adjustment block 401 is used to connect the lower surface of the adjustment bracket 105 to the rotating shaft 402. A rotating shaft 402 is rotatably arranged axially inside the adjustment block 401. The rotating shaft 402 is inserted into the interior of the adjustment block 401 and rotates with the insertion port inside the adjustment block 401. The rotating shaft 402 is used to drive the rear end of the adjustment bracket 105 to rotate. A bearing seat 404 is provided at each of the left and right ends of the rotating shaft 402. The bearing seats 404 are connected to the rotating shaft 402. 02. A mechanical seal connection is made. The bearing housing 404 is used to fix the rotating shaft 402 and prevent the rotating shaft 402 from falling off. A rotating cavity 403 is provided between the bearing housings 404. The height of the rotating cavity 403 can be twice the overall height of the adjusting block 401. The rotating cavity 403 must allow space for the adjusting block 401 to rotate left and right. The rotating cavity 403 prevents the adjusting block 401, which is driven synchronously when the rotating shaft 402 rotates, from colliding with the equipment base plate 106. A pad 405 is provided at the bottom of each bearing housing 404. The pad 405 can be fixed to the bearing housing 404 with bolts. The pad 405 is used to increase the height of the bearing housing 404.

[0021] Its effect is as follows: the adjusting block 401 is used to connect the lower surface of the adjusting bracket 105 with the rotating shaft 402. When the rotating shaft 402 rotates, it can drive the adjusting block 401 to rotate, thereby driving the rear part of the adjusting bracket 105 to rotate, and thus the rear part of the rotary kiln calcining furnace 100 can be angled.

[0022] like Figure 1 , 3As shown in Figure 4: The support component 300 includes an adjusting plate 301 fixed to the lower surface of the adjusting bracket 105. The lower surface of the adjusting bracket 105 and the upper surface of the adjusting plate 301 are bolted together. The adjusting plate 301 is used to connect the lower surface of the adjusting bracket 105 to the tilting knuckle 302. The lower surface of the adjusting plate 301 is provided with multiple tilting knuckles 302. The tilting knuckles 302 are bolted together to the lower surface of the adjusting plate 105. The tilting knuckles 302 are used to connect with the telescopic support rod 303 when the angle of the adjusting bracket 105 changes, thereby preventing the telescopic support rod from changing angle. 303 breaks off. Each tilting steering knuckle 302 has a telescopic support rod 303 at its bottom. The upper end of the telescopic support rod 303 is fixed to the tilting steering knuckle 302 by bolts. The telescopic support rod 303 is used to support the adjusting bracket 105 when it cooperates with the hydraulic lifting rod 203 to lift the adjusting bracket 105. Each telescopic support rod 303 has a positioning block 304 at its bottom. The positioning block 304 is fixed to the fixing part at the lower end of the telescopic support rod 303 by bolts or welding. The positioning block 304 is used to connect the bottom of the telescopic support rod 303 to the equipment base plate 106.

[0023] Its effects are as follows: the adjusting plate 301 is used to connect the lower surface of the adjusting bracket 105 with the tilt steering knuckle 302. The tilt steering knuckle 302 is used to connect with the telescopic support rod 303 when the angle of the adjusting bracket 105 changes, thereby preventing the telescopic support rod 303 from breaking due to bending. The telescopic support rod 303 is used to support the adjusting bracket 105 when it is lifted by the hydraulic lifting rod 203. It plays a supporting role both during and after the adjustment of the adjusting bracket 105.

[0024] like Figure 1 , 3 As shown in Figure 4, the lifting device 200 includes a connecting plate 201 fixed to the lower surface of the adjusting bracket 105. The lower surface of the adjusting bracket 105 is fixed to the connecting plate 201 with bolts. The connecting plate 201 is used to fix the lower surface of the adjusting bracket 105 to the connecting block 202. Multiple connecting blocks 202 are provided on the lower surface of the connecting plate 201. The connecting blocks 202 are fixed to the connecting plate 201 with bolts. The connecting blocks 202 are used to connect the connecting plate 201 to the telescopic end of the hydraulic lifting rod 203. A hydraulic lifting rod 203 is provided at the bottom of each connecting block 202. The hydraulic lifting rod 203 and the telescopic end are fixed to the lower surface of the connecting block 202 with bolts.

[0025] Its effect is as follows: the hydraulic lifting rod 203 is used to drive the front end of the adjusting bracket 105 to rise and fall, thereby driving the front end of the roasting furnace to rise and fall.

[0026] like Figure 1 , 3As shown in Figure 4: the bottom of the drive end of the hydraulic lifting rod 203 is at the same height as the bottom of the positioning block 304, the bottom of the positioning block 304 is at the same height as the bottom of the pad 405, and the bottom of the positioning block 304 is provided with a base plate 106. The bottom of the drive end of the hydraulic lifting rod 203 is fixed to the upper surface of the base plate 106 with bolts. The base plate 106 is used to fix the positioning block 304. The positioning block 304 is fixed to the upper surface of the base plate 106 with bolts. The drive end of the hydraulic lifting rod 203 and the pad 405 are fixed together. The lower surface of the pad 405 is fixed to the upper surface of the base plate 106 with bolts.

[0027] The effect is as follows: the equipment base plate 106 is used to fix the positioning block 304, the positioning block 304 is fixed to the upper surface of the equipment base plate 106 by bolts, and the driving end of the hydraulic lifting rod 203 and the pad block 405 are positioned at the same height.

[0028] like Figure 1 , 3 As shown: A compression packing sealing ring 107 is provided at both the front and rear ends of the heating chamber 102. The compression packing sealing ring 107 is made by filling the sealing cavity with packing made of soft thread, and the compression force generated by the pressure cap makes the packing press against the sealing surface, thereby producing a sealing effect, and thus heat-insulating and sealing the connection gap of the heating chamber 102.

[0029] Its effect is as follows: the compression packing seal ring 107 is used to seal the connection gap between the heating chamber 102 and the rotary kiln calcining furnace 100 drum, thereby reducing the heat dissipation rate of the heating chamber 102.

[0030] like Figure 1 , 2 As shown in Figure 3: The feed inlet of the quantitative conveyor 101 is equipped with a discharge pipe 500, which is welded and fixed to the feed inlet of the quantitative conveyor 101. The discharge pipe 500 is used to connect the quantitative conveyor 101 and the discharge hopper 501. The top of the discharge pipe 500 is connected to the discharge hopper 501, which is welded and connected to the discharge end of the discharge pipe 500. The discharge hopper 501 is used to feed the material to be roasted. A level gauge 502 is installed at the bottom of the discharge hopper 501. The level gauge 502 passes through the hopper wall of the discharge hopper 501 and enters the discharge hopper 501. Inside 01, the level gauge 502 is used to detect the material level in the feeding hopper 501. When the material level is low, the feeding will automatically stop and the material will form a seal to prevent air from entering the roasting furnace through the feeding pipe 500. An electric valve 503 is installed in the middle section of the feeding pipe 500. The electric valve 503 is connected to the feeding pipe 500 by a flange seal. The electric valve 503 is used to open and close the feeding pipe 500. The electric valve 503 is also used to seal the feeding end of the rotary kiln roasting furnace 100. In order to save manufacturing costs, only one of the level gauge 502 and the electric valve 503 needs to be installed.

[0031] Its effects are as follows: the feeding hopper 501 is used to feed the material to be roasted into the given conveyor 101; the material level gauge 502 is used to detect the material level in the feeding hopper 501; when the material level is low, the feeding will automatically stop and the material will form a seal to prevent air from entering the roasting furnace through the feeding pipe 500; the electric valve 503 is used to open and close the feeding pipe 500; the electric valve 503 is also used to seal the feeding end of the rotary kiln roasting furnace 100.

[0032] Working principle: The adjusting bracket 105 is connected and fixed to various components on the rotary kiln calciner 100. The lifting device 200 lifts the front end of the adjusting bracket 105, thereby raising the front of the rotary kiln calciner 100. Simultaneously, the angle adjusting component 400, along with the lifting device 200, raises the front end of the rotary kiln calciner 100, causing an angle change at the rear end of the rotary kiln calciner 100. This adjusts the tilt angle of the rotary kiln calciner 100 towards the discharge end, achieving the purpose of adjusting the tilt angle of the rotary kiln calciner 100. This is achieved through the support component 30. The 0 provides support when the angle of the adjusting bracket 105 changes, thereby reducing the load on the adjusting bracket 105 and enabling the rotary kiln roasting furnace 100 to be adjusted stably. The sealing ring 107 is tightened to seal the connection gap between the heating chamber 102 and the drum of the rotary kiln roasting furnace 100, thereby reducing the heat dissipation rate of the heating chamber 102. The material level gauge 502 detects the material level in the feeding hopper 501. When the material level is low, the feeding is automatically stopped and a seal is formed by the material to prevent air from entering the roasting furnace through the feeding pipe 500.

[0033] 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.
