[0002] For the heat treatment of powder materials, a rotary kiln or a tubular furnace device with continuous feeding and discharging of materials is usually adopted. When in use, the materials usually need to be placed in the rotary kiln or the tubular furnace device for heat treatment, and after the heat treatment is completed, the heat-treated materials are taken out.

[0003] However, the heat treatment method through the rotary kiln or the tubular furnace device is relatively cumbersome, the treatment is intermittent operation, the heat treatment speed is slow, continuous production cannot be achieved, and the production efficiency and heat utilization rate are low. Summary of the Utility Model

[0004] The embodiment of the present application provides a heat treatment device with high production efficiency, which can solve the problem of low production efficiency of the existing heat treatment method.

[0005] The present application provides a heat treatment device, including:

[0006] A feeding assembly;

[0007] A material channel, including a feeding end and a discharging end, the feeding assembly is communicated with the feeding end, and the feeding assembly is used for conveying materials into the material channel;

[0008] A heating assembly, used for heating the materials in the material channel;

[0009] A discharging assembly, communicated with the discharging end of the material channel, and the heated materials in the material channel flow out from the discharging end to the discharging assembly;

[0010] A cooling assembly, located between the discharging end of the material channel and the discharging assembly, and the cooling assembly is used for cooling the materials flowing out from the discharging end.

[0011] The heat treatment device provided by the embodiment of the present application conveys materials into the material channel by setting a feeding assembly, and heats the materials passing through the material channel by setting a heating assembly. By setting a discharging assembly, the materials heated in the material channel can be output through the discharging assembly, so that the heat treatment process of the materials can be made into a whole, and continuous production can be realized, thereby improving the efficiency and heat utilization rate. By setting a cooling assembly at the discharging end of the material channel, the materials heated through the material channel can be directly cooled after flowing out from the discharging end, so that the heat-treated materials can be quickly cooled, thereby preventing the heat-treated materials from being in a high-temperature state for a long time and affecting the properties of the materials.

[0012] In a possible implementation, the feeding assembly includes an intake pipeline and a feeding device; wherein,

[0013] The intake pipeline is communicated with the feeding end of the material channel;

[0014] The feeding device is located between the intake pipeline and the feeding end of the material channel, and the feeding device is used for conveying materials into the material channel;

[0015] The intake pipeline is used for inputting gas into the material channel, so that the gas conveyed by the intake pipeline into the material channel drives the materials conveyed by the feeding device into the material channel to enter the material channel from the feeding end, and flows out from the discharging end after passing through the material channel.

[0016] By arranging the feeding assembly to include an intake pipeline and a feeding device, and arranging the feeding device between the intake pipeline and the feeding end of the material channel, materials can be brought into the material channel by gas. Exemplarily, the materials can be solid powder materials, which can improve the efficiency of solid materials entering the material channel, and thus improve the production efficiency of the heat treatment equipment. In addition, bringing solid materials into the material channel by gas can mix the gas and the solid, that is to say, the gas can dilute the solid. Compared with heat treating pure solid materials, the heat treatment efficiency of the solid materials diluted by gas is higher.

[0017] In a possible implementation, the discharging assembly includes a feeding pipe, a solid-gas separation device, a discharging port and an air outlet; wherein,

[0018] The feeding pipe is communicated with the discharging end of the material channel;

[0019] The solid-gas separation device is communicated with the feeding pipe, the discharging port and the air outlet. The solid-gas separation device is used for separating the materials entering from the feeding pipe into gas and solid, discharging the solid at the discharging port, and discharging the gas at the air outlet.

[0020] With such an arrangement, the materials flowing out from the discharging end of the material channel can be separated, and thus the gas and the solid can be separated, so as to collect the heat-treated materials and improve the heat treatment efficiency.

[0021] In a possible implementation, the air pressure of the gas entering the feeding end of the material channel through the intake pipeline is less than or equal to 0.1 Mpa;

[0022] The solid-gas separation device is used to apply a negative pressure to the discharging end of the material channel, and the negative pressure value is greater than 0.3 Mpa and less than 0.4 Mpa.

[0023] With such a setting, a negative pressure can be formed at the feeding end of the material channel, and the inside of the material channel is also in a negative pressure state, and the negative pressure does not exceed 0.40 Mpa. This can ensure the safety performance of the material channel and also facilitate the suction of materials from the feeding end into the material channel, and then into the solid-gas separation device, thereby separating the gas and the solid, and then collecting the solid materials. This can improve the efficiency of the materials entering the material channel and further improve the production efficiency of the heat treatment equipment.

[0024] In a possible implementation manner, an air outlet pipeline is further included. One end of the air outlet pipeline is communicated with the air outlet, and the other end is communicated with the air inlet pipeline.

[0025] With such a setting, the gas in the air outlet pipeline can be input into the air inlet pipeline, so that the gas can be reused, and the recycling of the gas can be realized, and the cost can be reduced.

[0026] In a possible implementation manner, the heating component is a continuously power-adjustable electromagnetic induction heating component.

[0027] With such a setting, the heating component can achieve rapid temperature rise, thereby improving the efficiency of heat treatment, further improving the utilization efficiency of heat, and saving energy.

[0028] In a possible implementation manner, the heating component includes a heating element and an induction coil; wherein,

[0029] An accommodation cavity is formed inside the material channel. The heating element is located in the accommodation cavity. The outer wall of the accommodation cavity is spaced from the inner wall of the material channel, and a material cavity is formed between the outer wall of the accommodation cavity and the inner wall of the material channel;

[0030] A support structure is provided between the outer wall of the accommodation cavity and the inner wall of the material channel. One end of the support structure is connected to the outer wall of the accommodation cavity, and the other end is connected to the inner wall of the material channel;

[0031] The induction coil surrounds the outside of the material channel.

[0032] With such a setting, the heating of the material channel can be realized through the induction coil and the heating element arranged in the material channel. Among them, by applying a high-frequency alternating current to the induction coil, an alternating magnetic field with a continuously changing direction can be generated in the induction coil. Eddy currents will be generated inside the conductor (heating element) in the alternating magnetic field. The Joule effect of the eddy currents will cause the temperature of the conductor to rise, thus achieving the purpose of heating. By providing a support structure between the outer wall of the accommodation cavity and the inner wall of the material channel, the connection stability between the material channel and the accommodation cavity can be improved to enhance the uniform heating of the materials in the material channel.

[0033] In a possible implementation, the heating element is an electromagnetic induction heating element; wherein,

[0034] The electromagnetic induction heating element is a tungsten core, an iron core, a molybdenum core or a silicon carbide rod.

[0035] With such a setting, the heating efficiency can be improved, and the high-temperature resistance performance of the heating element can be improved.

[0036] In a possible implementation, a heat insulation structure is further provided outside the heating assembly; wherein,

[0037] The heat insulation structure surrounds the outside of the induction coil.

[0038] With such a setting, the heating assembly can be heat-insulated, thereby ensuring the heating effect of the heating assembly, preventing heat dissipation, and improving the heat utilization rate.

[0039] In a possible implementation, the heat treatment equipment further includes a control module; wherein,

[0040] The control module is electrically connected to the feeding assembly, the heating assembly, the discharging assembly and the cooling assembly;

[0041] The control module is used to control the working states of the feeding assembly, the heating assembly, the discharging assembly and the cooling assembly.

[0042] With such a setting, it is convenient to control the working states of the feeding assembly, the heating assembly, the discharging assembly and the cooling assembly, and then to centrally process and record the data of the feeding assembly, the heating assembly, the discharging assembly and the cooling assembly, ensuring that under negative pressure, the speed of the material passing through the material channel is stable and controllable, so as to achieve precise heating of the material.

[0043] In a possible implementation, the cooling assembly is an air-cooling assembly or a water-cooling assembly.

[0044] With such a setting, the design flexibility of the cooling assembly can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0076] Existing heat treatment equipment all uses static materials, especially for heat treatment above 500°C. Usually, a relatively long pretreatment time is selected. For example, the heating speed of resistance wires is slow, and the startup and shutdown generally exceed 1 hour to reach a heat treatment temperature above 500°C, resulting in serious energy waste for heat treatment in seconds or milliseconds.

[0077] For rotary kiln or tubular furnace devices with continuous feeding and discharging of materials, the shortest heat treatment time for general materials is more than 10 minutes, and shorter heat treatment time control cannot be achieved. In addition, existing rapid heat treatment equipment all operates intermittently, cannot achieve continuous production, and has low production efficiency and heat utilization rate.

[0078] To solve the above technical problems, the embodiments of the present application provide a heat treatment equipment, which has a fast heat treatment speed, can achieve continuous operation, improve production efficiency, and improve heat utilization rate.

[0079] The heat treatment equipment provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0080] Figure 1 It is a framework schematic diagram of a heat treatment equipment provided by the embodiments of the present application.

[0081] The embodiments of the present application provide a heat treatment equipment 100, as Figure 1As shown in the figure, the heat treatment device 100 may include a feeding assembly 110, a material channel 120, a heating assembly 130, a discharging assembly 140, and a cooling assembly 150. Among them, the material channel 120 includes a feeding end 121 and a discharging end 122. The feeding assembly 110 is communicated with the feeding end 121, and the feeding assembly 110 is used to convey materials into the material channel 120. The heating assembly 130 is used to heat the materials in the material channel 120. The discharging assembly 140 is communicated with the discharging end 122 of the material channel 120, and the heated materials in the material channel 120 flow out from the discharging end 122 to the discharging assembly 140. The cooling assembly 150 is located between the discharging end 122 of the material channel 120 and the discharging assembly 140, and the cooling assembly 150 is used to cool the materials flowing out from the discharging end 122.

[0082] In the heat treatment device 100 provided by the embodiment of the present application, by providing the feeding assembly 110 to convey materials into the material channel 120, and by providing the heating assembly 130 to heat the materials passing through the material channel 120. By providing the discharging assembly 140, the materials heated in the material channel 120 can be output through the discharging assembly 140, so that the heat treatment process of the materials can be made into a whole, thereby realizing continuous production, and further improving the efficiency and heat utilization rate. By providing the cooling assembly 150 at the discharging end 122 of the material channel 120, the materials heated by the material channel 120 can be directly cooled after flowing out from the discharging end 122, so that the heat-treated materials can be quickly cooled down, thereby preventing the heat-treated materials from being in a high temperature state for a long time and affecting the properties of the materials.

[0083] Exemplarily, the material channel 120 may be a high-temperature resistant ceramic tube, for example, a corundum tube, etc. In the embodiment of the present application, the material of the material channel 120 is not further limited.

[0084] In a possible implementation manner, as Figure 2 shown, the feeding assembly 110 includes an air inlet pipeline 111 and a feeding device 112. Among them, the air inlet pipeline 111 is communicated with the feeding end 121 of the material channel 120. The feeding device 112 is located between the air inlet pipeline 111 and the feeding end 121 of the material channel 120, and the feeding device 112 is used to convey materials into the material channel 120. The air inlet pipeline 111 is used to input gas into the material channel 120, so that the gas conveyed into the material channel 120 by the air inlet pipeline 111 drives the materials input into the material channel 120 by the feeding device 112 to enter the material channel 120 from the feeding end 121 and flow out from the discharging end 122 after passing through the material channel 120.

[0085] By providing the feeding assembly 110 with an intake pipeline 111 and a feeding device 112, and arranging the feeding device 112 between the intake pipeline 111 and the feeding end 121 of the material channel 120, the material can be carried into the material channel 120 by the gas.

[0086] Exemplarily, the material can be solid powder material. The powder material can be blown by the gas and then mixed with the gas, and carried into the material channel 120 by the gas. This can improve the efficiency of the solid material entering the material channel 120, and further improve the production efficiency of the heat treatment equipment 100. In addition, by carrying the solid material into the material channel 120 by the gas, the gas and the solid can be mixed, that is to say, the gas can dilute the solid. Compared with heat treating pure solid material, the heat treatment efficiency of the solid material diluted by the gas is higher.

[0087] In a possible implementation, the discharging assembly 140 includes a feed pipe 141, a solid-gas separation device 142, a discharge port 143 and an air outlet 144. Among them, the feed pipe 141 is communicated with the discharging end 122 of the material channel 120. The solid-gas separation device 142 is communicated with the feed pipe 141, the discharge port 143 and the air outlet 144. The solid-gas separation device 142 is used to separate the material entering from the feed pipe 141 into gas and solid, discharge the solid at the discharge port 143, and discharge the gas at the air outlet 144.

[0088] With such an arrangement, the material flowing out from the discharging end 122 of the material channel 120 can be separated, and then the gas and the solid can be separated, so as to collect the heat-treated material and improve the heat treatment efficiency.

[0089] In a possible implementation, the air pressure of the gas entering the feeding end 121 of the material channel 120 through the intake pipeline 111 is less than or equal to 0.1 Mpa. The solid-gas separation device 142 generates a negative pressure applied to the discharging end 122 of the material channel 120, and the negative pressure value is greater than 0.3 Mpa and less than 0.4 Mpa.

[0090] Exemplarily, the positive pressure input by the inlet pipeline to the feeding end 121 of the material channel 120 is between 0 and 0.1 Mpa, and the negative pressure applied by the solid-gas separation device 142 to the discharging end 122 of the material channel 120 is between 0.3 Mpa and 0.4 Mpa. This will create a negative pressure in the material channel 120, which is convenient for the material to be sucked into the material channel 120 from the feeding end 121. Among them, the inside of the material channel 120 is also in a negative pressure state, and the negative pressure value does not exceed 0.40 Mpa.

[0091] With such a setting, a negative pressure can be formed at the feeding end 121 of the material channel 120, and the inside of the material channel 120 is also in a negative pressure state, and the negative pressure does not exceed 0.40 Mpa. This can ensure the safety performance of the material channel 120 and also facilitate the suction of materials from the feeding end 121 into the material channel 120, and then into the gas-solid separation device 142, thereby separating gas and solids, and then collecting solid materials. This can improve the efficiency of materials entering the material channel 120, and further improve the production efficiency of the heat treatment equipment 100.

[0092] Using gas to quickly move materials can achieve uniform movement of materials with a stable pressure difference and flow rate, and thus achieve precise control of the heat treatment time. In cooperation with the intake pipeline 111 and the gas-solid separation device, continuous processing of materials can be realized, which is easy to be applied in industrial continuous production.

[0093] Exemplarily, the intake pipeline 111 can be connected to the feeding fan 180, and the feeding fan 180 is used to input gas into the intake pipeline 111. The feeding fan 180 needs to be connected to an external gas source to supplement the gas loss inside the system. Among them, the external gas source can be nitrogen, etc. In the embodiments of the present application, the type of gas is not further limited.

[0094] Exemplarily, a pressure control valve 1111 can be provided on the intake pipeline 111, and the pressure control valve 1111 is used to control the air pressure of the intake pipeline 111 entering the material channel 120.

[0095] Exemplarily, the feeding device 112 can be an ultrasonic spiral conveying device, so that materials can enter the material channel 120 at a uniform speed. Of course, in other embodiments, the feeding device 112 can also be set to other structures, which are not further limited in the embodiments of the present application.

[0096] In some embodiments, a pressure monitoring device (not shown in the figure) can also be included. The pressure monitoring device is used to monitor the air pressure inside the material channel 120. Ensure that the air pressure inside the material channel 120 is in a slightly negative pressure state at high temperatures. For example, the negative pressure value of the air pressure inside the material channel 120 is less than 0.4 Mpa. For example, it can be 0.35 Mpa, 0.3 Mpa, 0.25 Mpa, 0.2 Mpa, 0.15 Mpa, 0.1 Mpa, etc. In the embodiments of the present application, the air pressure value inside the material channel 120 is not further limited, as long as it is negative pressure and less than 0.4 Mpa.

[0097] By controlling the negative pressure value inside the material channel 120, the safety performance of the material channel 120 can be ensured, and the speed of materials passing through the material channel 120 can be continuously adjusted between 1 - 15 m / s. Furthermore, the heat treatment time can be adjusted according to needs, and the accuracy of heat treatment can be improved.

[0098] In a possible implementation, an outlet pipeline 170 is further included. One end of the outlet pipeline 170 is communicated with an air outlet 144, and the other end is communicated with an inlet pipeline 111.

[0099] With such a setting, the gas in the outlet pipeline 170 can be input into the inlet pipeline 111, so that the gas can be reused, and thus the recycling of the gas is realized, and the cost is reduced.

[0100] In a possible implementation, the heating component 130 is a continuously power-adjustable electromagnetic induction heating component 130.

[0101] With such a setting, the heating component 130 can achieve rapid temperature rise, and can stably achieve ultra-fast heat treatment from milliseconds to seconds, thereby improving the efficiency of heat treatment, improving the utilization efficiency of heat, and saving energy.

[0102] By adopting the electromagnetic heating component 130, the power can be regulated, eddy currents can be generated in cooperation with the heating body, and the high-temperature resistant ceramic material can be used as the material channel 120 to realize uniform heating of the material, effectively improving the heating efficiency, quickly realizing startup and shutdown, and improving the efficiency.

[0103] Exemplarily, the heating component 130 can be connected to an insulated gate bipolar transistor (IGBT), and the power output of the heating component 130 is continuously and stably controlled through the IGBT to stably achieve ultra-fast heat treatment from milliseconds to seconds.

[0104] In a possible implementation, a temperature monitoring device can also be included. The temperature monitoring device is used to monitor the temperature of the heating component 130. In this way, the temperature of the material channel 120 can be controlled according to the temperature of the heating component 130, and thus precise heating of the material can be realized.

[0105] In a possible implementation, as Figure 3 and Figure 4 shown, the heating component 130 can include a heating element 131 and an induction coil 132. Among them, a receiving cavity is formed inside the material channel 120, the heating element 131 is located in the receiving cavity, the outer wall 123 of the receiving cavity is spaced from the inner wall of the material channel 120, and a material cavity 124 is formed between the outer wall 123 of the receiving cavity and the inner wall of the material channel 120. A support structure 125 is provided between the outer wall 123 of the receiving cavity and the inner wall of the material channel 120. One end of the support structure 125 is connected to the outer wall 123 of the receiving cavity, and the other end is connected to the inner wall of the material channel 120. The induction coil 132 surrounds the outside of the material channel 120.

[0106] With such a setting, the heating of the material channel 120 can be achieved through the induction coil 132 and the heating element 131 disposed in the material channel 120. Among them, by applying a high-frequency alternating current to the induction coil 132, an alternating magnetic field with a continuously changing direction can be generated in the induction coil 132. Eddy currents will be generated inside the conductor (heating element 131) in the alternating magnetic field. The Joule effect of the eddy currents will cause the temperature of the conductor to rise, thereby achieving the purpose of heating. By providing a support structure 125 between the outer wall 123 of the accommodation cavity and the inner wall of the material channel 120, the connection stability between the material channel 120 and the outer wall 123 of the accommodation cavity can be improved, and the structural strength of the entire material channel 120 can be enhanced, so that the material can pass through the material channel 120 homogenously under high-speed air flow. The support structure 125 also has the ability to disperse the two-fluid, so as to improve the uniformity of the material heated in the material channel 120.

[0107] In a possible implementation manner, the heating element 131 can be an electromagnetic induction heating element. For example, a tungsten core, an iron core, a molybdenum core, or a silicon carbide rod, etc. Of course, in other embodiments, the heating element 131 can also be an alloy material containing tungsten, iron, high manganese steel, or molybdenum. In the embodiments of the present application, the material of the heating element 131 is not further limited.

[0108] With such a setting, the heating efficiency can be improved, and the high-temperature resistance performance of the heating element can be enhanced. Second-level or millisecond-level heating treatment can be achieved, thereby improving the working efficiency of the heat treatment equipment.

[0109] It should be noted that the heating assembly 130 can also be other structures. For example, the heating assembly 130 can also be disposed outside the material channel 120 for heating the material in the material channel 120.

[0110] Exemplarily, both the material channel 120 and the outer wall 123 of the accommodation cavity can be high-temperature resistant ceramic tubes. The accommodation cavity is embedded in the material channel 120, so that the material channel 120 and the accommodation cavity form a double-layer nested high-temperature resistant ceramic tube. The heating element 131 is located in the accommodation cavity inside the material channel 120 to achieve the heating of the material channel 120.

[0111] In a possible implementation manner, a heat insulation structure 133 is further provided outside the heating assembly 130. Among them, the heat insulation structure 133 surrounds the outside of the induction coil 132. With such a setting, the heating assembly 130 can be heat-insulated, thereby ensuring the heating effect of the heating assembly 130, preventing heat dissipation, and improving the heat utilization rate.

[0112] It should be noted that in the embodiments of the present application, the specific structure of the heat insulation structure 133 is not further limited.

[0113] In a possible implementation, the heat treatment device 100 further includes a control module 160. The control module 160 is electrically connected to the feeding assembly 110, the heating assembly 130, the discharging assembly 140, and the cooling assembly 150, and is configured to control the operating states of the feeding assembly 110, the heating assembly 130, the discharging assembly 140, and the cooling assembly 150.

[0114] With such an arrangement, it is convenient to control the operating states of the feeding assembly 110, the heating assembly 130, the discharging assembly 140, and the cooling assembly 150. Furthermore, the data of the feeding assembly 110, the heating assembly 130, the discharging assembly 140, and the cooling assembly 150 can be centrally processed and recorded, ensuring that under negative pressure, the speed of the material passing through the material channel 120 is stable and controllable, so as to achieve precise heating of the material.

[0115] In a possible implementation, the cooling assembly 150 is an air-cooling assembly or a water-cooling assembly. In the embodiments of the present application, the specific structure of the cooling assembly 150 is not further limited. With such an arrangement, the design flexibility of the cooling assembly 150 can be improved.

[0116] Exemplarily, a 2-meter-long corundum material channel 120 can be adopted, with a 1-meter-long high manganese steel heating element 131 as the inner core. A water-cooling assembly is provided at the discharging end 122 of the material channel 120. The induction coil 132 is a high-frequency heating coil, and the IGBT is electrically connected to the induction coil 132 to achieve continuously adjustable power.

[0117] Among them, the diameter of the heating element 131 can be 35 mm. An accommodation cavity surrounded by corundum tubes is provided inside the material channel 120, and the inner diameter of the accommodation cavity can be 40 mm. The inner diameter of the material channel 120 can be 55 mm. Axially of the material channel 120, a plurality of support structures 125 are arranged at intervals, and the interval distance between two adjacent support structures 125 can be 200 mm. The support structure 125 can be used to connect the inner wall of the material channel 120 and the outer wall 123 of the accommodation cavity, and to achieve uniform dispersion of the material.

[0118] The negative pressure value at the feeding end 121 can be 0.3 - 0.4 Mpa. An ultrasonic spiral conveying device is used for feeding.
