Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment kilns, and more specifically, to a quick exhaust type debinding furnace. Background Art

[0002] In the field of basic functional materials such as electronic ceramics, powder metallurgy, and components, the production process is divided into pulping, pressing, debinding, sintering, etc. Debinding is the process of decomposing and volatilizing the organic components in the adhesive used in the product. If the debinding is not sufficient, it will affect the performance of the final sintered body. Therefore, the debinding process is usually completed in a professional debinding furnace.

[0003] The prior art discloses a debinding furnace, comprising a furnace body with a furnace chamber and a furnace door for opening and closing the furnace chamber, the furnace chamber being connected to an air intake device and an exhaust device, and also comprising an exhaust gas treatment device connected to an outlet end of the exhaust device for heating and decomposing exhaust gas discharged by the exhaust device, the exhaust gas treatment device being connected to the air intake device and supplying part of the exhaust gas after heating and decomposition to the air intake device for passing into the furnace; the exhaust gas treatment device comprising a shell having a combustion chamber and an exhaust pipe connected to the combustion chamber, a heating element for heating exhaust gas being installed in the combustion chamber, the combustion chamber being connected to the outlet end of the exhaust device and the air intake device; the air intake device comprising an air intake pipe connected to an air source and an air intake cavity arranged on the furnace body and located on one side of the furnace, the air intake pipe being connected to the air intake cavity, and the air intake cavity being connected to the furnace through an air intake hole arranged on the side wall of the furnace.

[0004] However, in the prior art, the debinding furnace has only one cavity, and only one air inlet and one exhaust hole are provided respectively. The air inlet and the exhaust hole are respectively provided on the inner diagonal of the cavity. The path between the air inlet and the air outlet is very far, and the air flow is restricted. There are technical problems such as low exhaust efficiency and slow gas flow of the debinding furnace. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of low exhaust efficiency and slow gas flow in the prior art and to provide a debinding furnace with accelerated exhaust.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A accelerated exhaust type debinding furnace comprises a furnace body, wherein a cavity is arranged in the furnace body, an air inlet column with a hollow structure is arranged in the cavity, an air inlet channel is connected in the air inlet column, and a plurality of air inlet holes connected to the air inlet channel are distributed on the outer wall of the air inlet column; a plurality of hollow structure partitions are vertically arranged in the cavity, and the plurality of partitions divide the cavity into a plurality of placement areas for placing samples, the air inlet holes can transport reaction gas to the plurality of placement areas, an air outlet channel is connected in the partition, and a plurality of air outlet holes connected to the air outlet channel are distributed on the partition.

[0008] The utility model discloses an accelerated exhaust type debinding furnace, wherein a plurality of air inlet holes connected to the air inlet channel are arranged on the outer wall of the air inlet column, and a plurality of air outlet holes connected to the air outlet channel are arranged on the partition plate. Since the partition plate divides the cavity into a plurality of placement areas for placing samples, the air inlet holes can transport reaction gases into the plurality of placement areas, thereby greatly shortening the path between the air inlet holes and the air outlet holes, improving the fluidity of the air flow, accelerating the reaction gas circulation in the cavity, and effectively solving the technical problems of low exhaust efficiency and slow gas flow in the prior art.

[0009] Furthermore, the length direction of the partition is parallel to the radial direction with the air intake column as the center, and a plurality of the partitions are evenly distributed on the periphery of the air intake column. The air intake column is rotatably connected to the furnace body and can rotate around the axial direction. The length direction of the partition is parallel to the radial direction with the air intake column as the center, so that a plurality of partitions are evenly distributed on the periphery of the air intake column. When the air intake column rotates around the axial direction, the reaction gas can be delivered to each placement area to improve the fluidity of the gas flow.

[0010] Furthermore, the inlet channel is connected to the top of the inlet column, and the diameters of several of the inlet holes decrease along the flow direction of the reaction gas; the outlet channel is connected to the bottom of the partition, and the diameters of several of the outlet holes decrease along the flow direction of the reaction gas. By reducing the diameter of the inlet holes and the diameter of the outlet holes along the flow direction of the reaction gas, the inlet holes on the inlet column and the outlet holes on the partition are adapted to each other, which can buffer the airflow in the cavity and prevent the distribution of the gas in the cavity from being affected by excessive intake or exhaust.

[0011] Furthermore, a moving block is provided in the air inlet channel, and the moving block can reciprocate along the air inlet direction of the air inlet channel to increase the flow rate of the reaction gas entering the air inlet column. The moving block is reciprocated along the air inlet direction of the air inlet channel to promote the flow of the reaction gas and increase the flow rate of the reaction gas entering the air inlet column.

[0012] Further, the moving block includes a conical stage, and the diameter of the top of the conical stage is larger than the diameter of the bottom of the conical stage. When the diameter of the top of the conical stage is larger than the diameter of the bottom of the conical stage, the reaction gas can flow downward faster when the conical stage moves downward, thereby increasing the flow rate of the reaction gas entering the inlet column.

[0013] Furthermore, the moving block further comprises a sliding table arranged at the bottom of the conical table, the sliding table being slidably arranged in the air inlet passage, racks being arranged on both sides of the sliding table, swing gears respectively meshing with the racks on both sides and a driving device for driving the swing gears to rotate being arranged in the air inlet passage, the central angle of the swing gear being less than 180 degrees, the swing gears on both sides meshing with the racks in sequence and rotating in the same direction. Since the central angle of the swing gear is less than 180 degrees, the swing gears on both sides meshing with the racks in sequence and rotating in the same direction, the sliding table can be slid up and down by driving the swing gears to rotate using the driving device.

[0014] Furthermore, the driving device includes driven gears respectively arranged on both sides of the sliding platform, driving gears arranged between the driven gears on both sides and respectively meshing with the driven gears on both sides, and a motor for driving the driving gears to rotate, the driven gears and the driving gears are both rotatably arranged in the air intake passage, and the swing gear is coaxially fixed to the driven gears. By driving the driving gears to rotate with the motor, the driven gears on both sides can rotate in the same direction, so that the swing gears on both sides can mesh with the racks in sequence.

[0015] Furthermore, a pressurized channel is provided in the moving block, the cross-sectional profile of the pressurized channel is conical, and the diameter of the top of the pressurized channel is greater than the diameter of the bottom of the pressurized channel. Since the cross-sectional profile of the pressurized channel is conical, and the diameter of the top of the pressurized channel is greater than the diameter of the bottom of the pressurized channel, when the moving block moves upward, the reaction gas will be gathered into the pressurized channel, and the pressurized channel will have a contraction and compression effect on the reaction gas, thereby increasing the speed of the reaction gas entering the intake column, so that the upward and downward movement of the moving block can have a pressurization effect.

[0016] Furthermore, the moving block is a porous honeycomb structure, a heating element is provided in the moving block, and the heating element can contact the reaction gas in the air inlet channel. Since the moving block is a porous honeycomb structure, the heating element can contact the reaction gas in the air inlet channel to heat the reaction gas.

[0017] Furthermore, the moving block is provided with several layers of honeycomb hole shells from the inside to the outside, and the heating element is provided between adjacent honeycomb hole shells. The heating element is provided between adjacent honeycomb hole shells to enhance the heating effect.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model discloses an accelerated exhaust type debinding furnace, wherein a plurality of air inlet holes connected to the air inlet channel are arranged on the outer wall of the air inlet column, and a plurality of air outlet holes connected to the air outlet channel are arranged on the partition plate. Since the partition plate divides the cavity into a plurality of placement areas for placing samples, the air inlet holes can transport reaction gases into the plurality of placement areas, thereby greatly shortening the path between the air inlet holes and the air outlet holes, improving the fluidity of the air flow, accelerating the reaction gas circulation in the cavity, and effectively solving the technical problems of low exhaust efficiency and slow gas flow in the prior art.
