Description

Technical Field

[0001] This utility model relates to the field of material roasting and impurity removal technology, specifically to a low-temperature roasting and impurity removal device. Background Technology

[0002] Material roasting and impurity removal refers to the process of removing impurities and volatile components from materials by heating them under conditions below their melting temperature, causing a series of physical and chemical changes.

[0003] In the prior art, materials are often roasted and impurity removed using low-temperature roasting equipment. The low-temperature roasting and impurity removal equipment mainly consists of a furnace body, a feeding screw, and a hot air flow duct. The material moves slowly downward from the furnace body through the feeding screw, and the hot air flow duct introduces hot air from the bottom of the furnace body. The slowly flowing hot air pyrolyzes the material, and the unvolatile solid impurities settle at the bottom of the furnace body.

[0004] However, during the process of unvolatile solid impurities settling at the bottom of the furnace, due to the slow flow of hot air, some solid impurities may fall into the hot air duct, causing blockage of the hot air duct and ultimately affecting the effect of hot air flow into the furnace. Utility Model Content

[0005] The purpose of this utility model is to provide a low-temperature roasting and impurity removal device to solve the technical problem in the prior art where, during the process of non-volatile solid impurities settling at the bottom of the furnace, due to the slow flow of hot air, solid impurities may fall into the hot air flow duct, causing blockage of the hot air flow duct and ultimately affecting the effect of hot air flow into the furnace.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A low-temperature roasting and impurity removal device includes:

[0008] The furnace body has an air inlet shell fixedly connected to its bottom end. The top end of the air inlet shell has several air inlets along the axis. The bottom end of the air inlet shell is fixedly connected to a connecting cylinder. The bottom end of the connecting cylinder is fixedly connected to a guide pipe. The upper and lower ends of the connecting cylinder are respectively connected to a cylinder and a guide pipe.

[0009] A baffle plate is provided on the top of the air intake shell, and a plurality of cylinders are provided between the baffle plate and the air intake shell. The upper and lower ends of the cylinders are respectively fixedly connected to the baffle plate and the air intake shell.

[0010] The feeding assembly is fixedly connected to the top of the furnace body, and a bearing assembly is fixedly connected to the bottom of the feeding assembly.

[0011] As a further embodiment of this utility model: support rods are fixedly connected to the bottom of the furnace body around its perimeter, and the height of the support rods is higher than the height of the gas guide pipe.

[0012] As a further embodiment of this utility model: a plurality of support plates are provided between the connecting cylinder and the air inlet shell, and the plurality of support plates are respectively located around the connecting cylinder, with both ends of the support plates being fixedly connected to the air inlet shell and the connecting cylinder respectively.

[0013] As a further embodiment of this utility model, the air intake shell is conical in shape.

[0014] As a further embodiment of this utility model: the baffle plate is circular and covers the air inlet on a horizontal plane.

[0015] As a further embodiment of this utility model: the bearing component includes a bearing plate and a fixing plate. The bearing plate is provided in two sets and is semi-circular in shape. The bearing plate is slidably connected to the inner wall of the furnace. The two ends of the fixing plate are fixedly connected to the bearing plate respectively, and the fixing plate is fixedly connected to the bottom end of the feeding component.

[0016] As a further embodiment of this utility model, air vents are provided through all four sides of the support plate.

[0017] As a further embodiment of this utility model: the feeding assembly includes a driver and a telescopic rod, the driver is disposed on the top of the furnace body, and the upper and lower ends of the telescopic rod are respectively fixedly connected to the driver and the fixing plate.

[0018] As a further embodiment of this utility model: connecting plates are fixedly connected to both ends of the driver, and the side ends of the connecting plates are fixedly connected to the top of the furnace body.

[0019] As a further embodiment of this utility model: the two ends of the connecting plate are respectively supported and connected to the sealing plate, the sealing plate has a through-hole for air outlet, the top of the sealing plate is fixedly connected to the air outlet pipe, and the air outlet and the air outlet pipe are interconnected.

[0020] The beneficial effects of this utility model are:

[0021] 1. The material is placed on the bearing assembly, and the feeding assembly slowly conveys the material assembly vertically downwards from the top of the furnace body. At this time, the hot air flow enters the connecting cylinder through the air guide pipe, and then the hot air flow flows out from the air inlet at the top of the air inlet shell. The hot air flow flows vertically upwards and roasts the material on the bearing assembly. When the material is roasted, the pyrolysis substances of the material flow upwards with the hot air flow and are discharged. When the impurities formed on the bearing assembly fall vertically downwards, the baffle plate blocks the impurities, thereby preventing the impurities from clogging the air inlet.

[0022] 2. When impurities fall to the bottom of the furnace body, the air inlet shell is located inside the furnace body. The air inlet shell can block the accumulated impurities and prevent the impurities accumulated at the bottom of the furnace body from entering the air inlet shell through the air inlet. This further avoids the impact of accumulated impurities on the air inlet. When the hot air flows out of the air inlet, the baffle plate blocks the hot air flow. The hot air flow first flows to the surroundings and then flows vertically upward. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-6 As shown, a low-temperature roasting and impurity removal device includes: a furnace body 1, a baffle plate 12, and a feeding assembly.

[0033] The bottom of the furnace body 1 is fixedly connected to an air inlet shell 14. The top of the air inlet shell 14 has several air inlets 17 along its axis. A connecting cylinder 15 is fixedly connected to the bottom of the air inlet shell 14. A guide pipe 7 is fixedly connected to the bottom of the connecting cylinder 15. The upper and lower ends of the connecting cylinder 15 are respectively connected to a cylinder 13 and the guide pipe 7. A baffle plate 12 is disposed on the top of the air inlet shell 14. Several cylinders 13 are disposed between the baffle plate 12 and the air inlet shell 14. The upper and lower ends of the cylinders 13 are fixedly connected to the baffle plate 12 and the air inlet shell 14, respectively. The feeding assembly is fixedly connected to the top of the furnace body 1. A bearing is fixedly connected to the bottom of the feeding assembly. The material is placed on the supporting component, and the feeding component slowly conveys the material component vertically downward from the top of the furnace body 1. At this time, the hot air flow enters the connecting cylinder 15 through the air guide pipe 7, and then the hot air flow flows out from the air inlet 17 opened at the top of the air inlet shell 14. The hot air flow flows vertically upward and roasts the material on the supporting component. When the material is roasted, the pyrolysis substances of the material flow upward with the hot air flow and are discharged. When the impurities formed on the supporting component fall vertically downward, the baffle plate 12 blocks the impurities, thereby preventing the impurities from clogging the air inlet 17.

[0034] When impurities fall to the bottom of the furnace body 1, the air inlet shell 14 is located inside the furnace body 1. The air inlet shell 14 can block the accumulated impurities and prevent the impurities accumulated at the bottom of the furnace body 1 from entering the air inlet shell 14 through the air inlet 17, thereby further preventing the accumulated impurities from blocking the air inlet 17. When the hot air flows out from the air inlet 17, the baffle plate 12 blocks the hot air flow. The hot air flow first flows to the surroundings and then flows vertically upward.

[0035] In some specific implementations, support rods 6 are fixedly connected to the bottom of the furnace body 1 around its perimeter. The height of the support rods 6 is higher than that of the gas guide pipe 7. The bottom of the support rods 6 is fixed to the ground. The support rods 6 provide support for the furnace body 1. The height of the support rods 6 is limited to prevent the gas guide pipe 7 from contacting the ground.

[0036] In some specific embodiments, a plurality of support plates 18 are provided between the connecting cylinder 15 and the air inlet shell 14. The plurality of support plates 18 are respectively located around the connecting cylinder 15. The two ends of the support plates 18 are fixedly connected to the air inlet shell 14 and the connecting cylinder 15, respectively. The top end of the connecting cylinder 15 is fixedly connected to the air inlet shell 14. The bottom of the connecting cylinder 15 is fixed to the air inlet shell 14 through the support plates 18, thereby ensuring that both the upper and lower ends of the connecting cylinder 15 can be fixed on the air inlet shell 14.

[0037] In some specific embodiments, the air intake shell 14 is conical in shape. When impurities fall from the support component, the shape of the air intake shell 14 can ensure that the impurities slide down along the outer wall of the air intake shell 14, thereby avoiding the phenomenon of impurities adhering to the outer wall of the air intake shell 14.

[0038] In some specific implementations, the baffle plate 12 is circular and covers the air inlet 17 on a horizontal plane. The shape of the baffle plate 12 can ensure that the baffle plate 12 can more fully protect the top of the air inlet 17 from impurities. At the same time, according to geometric principles, the shape of the baffle plate 12 saves more materials.

[0039] In some specific embodiments, the supporting component includes a supporting plate 10 and a fixing plate 11. The supporting plate 10 is provided in two sets and is semi-circular in shape. The supporting plate 10 is slidably connected to the inner wall of the furnace body 1. The two ends of the fixing plate 11 are fixedly connected to the supporting plate 10 respectively. The fixing plate 11 is fixedly connected to the bottom end of the feeding component. When the material is placed on the supporting plate 10, the feeding component drives the fixing plate 11 to move vertically downward. The fixing plate 11 drives the supporting plate 10 to move downward along the inner wall of the furnace body 1, so that the supporting plate 10 carries the material and moves vertically downward in the furnace body 1.

[0040] In some specific implementations, air inlets 19 are provided around the support plate 10. When the hot air flows vertically upward, the hot air will pass through the fixed plate 11 and come into contact with the material.

[0041] In some specific implementations, the feeding assembly includes a driver 4 and a telescopic rod 9. The driver 4 is located at the top of the furnace body 1, and the upper and lower ends of the telescopic rod 9 are fixedly connected to the driver 4 and the fixing plate 11, respectively. When the feeding assembly is running, the driver 4 drives the telescopic rod 9 to extend vertically downward, and the telescopic rod 9 moves vertically downward with the fixing plate 11.

[0042] In some specific implementations, the driver 4 is fixedly connected to two ends of a connecting plate 5, and the side of the connecting plate 5 is fixedly connected to the top of the furnace body 1. The driver 4 is fixed by the fixed connecting plate 5 and the top of the furnace body 1.

[0043] In some specific implementations, the connecting plate 5 is respectively supported and connected to the sealing plate 2 at both ends. The sealing plate 2 has a through-hole 8 and a gas outlet 3 is fixedly connected to the top of the sealing plate 2. The gas outlet 8 and the gas outlet 3 are interconnected. When the material is placed on the bearing component, the sealing plate 2 is fixed to the top of the furnace body 1 and the sealing plate 2 seals the furnace body 1. When the hot air flows to the top of the furnace body 1, the hot air flows out of the furnace body 1 from the gas outlet 8 and then is discharged along the gas outlet 3.

[0044] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
