Description

Technical Field

[0001] This invention belongs to the field of vacuum sintering furnace technology, specifically relating to a vacuum sintering furnace for hammerhead processing. Background Technology

[0002] The hammerhead, more accurately defined as the hammer head of a hammer crusher, is a core component of a hammer crusher. Arranged on the hammer shaft of the crusher rotor, the hammerhead directly impacts the material during high-speed operation, ultimately crushing it into suitable particle sizes. To improve the crusher's performance, a split-type hammerhead is required. During production, the raw materials need to be sintered in a vacuum sintering furnace to enhance the hammerhead's performance. A vacuum sintering furnace is a furnace that performs protective sintering of heated materials in a vacuum environment. It is a complete set of equipment that uses medium-frequency induction heating under vacuum or protective atmosphere conditions to sinter cemented carbide cutter heads and various metal powder pressed bodies. It is designed for the industrial production of cemented carbide, dysprosium, and ceramic materials, and it utilizes various heating methods, such as resistance heating, induction heating, and microwave heating.

[0003] Existing technology CN222048576U discloses an improved vacuum sintering furnace, including a vacuum sintering furnace with support plates installed on both the lower left and lower right sides. A storage device is installed between the front and rear inner walls of the vacuum sintering furnace. A sealing cover is installed on the left end of the vacuum sintering furnace, and a mounting base is installed on the upper end of the vacuum sintering furnace. A detection device is installed at the front end of the mounting base, and a vacuum pumping device is installed at the rear end of the mounting base and the rear right side of the vacuum sintering furnace. This device lacks any external cooling structure, relying solely on its internal cooling system for cooling, resulting in a long cooling time and consequently reducing the production efficiency of the hammerheads.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The high-pressure blower of this invention can draw the exhaust gas after the internal parts of the tank are removed into the condenser through the outflow channel. The cold air unit sends the cold air to the cooling tank, and the cold air quickly cools the hot air in the condenser. After the cold air becomes hot, it returns to the cold air unit for cooling, ensuring the rapid cooling of the sintering furnace. The cooled exhaust gas is sequentially sprayed into the sintering furnace body through the connecting pipe B, the high-pressure blower, the connecting pipe A, and the top distribution pipe, thereby accelerating the cooling of the sintering furnace and greatly improving the processing efficiency of the sintering furnace.

[0021] 2. By installing the replacement unit, the present invention monitors the stripping function of the stripping table C by changing the total weight of the stripping table C, which facilitates the disassembly of the stripping table C with weaker stripping function, thereby allowing the stripping table C to maintain a stronger stripping function and ensuring the stripping of waste in the exhaust gas. Furthermore, by installing multiple stripping tables C and replacing each stripping table C individually, the stripping function of the stripping table C can be guaranteed.

[0022] By installing the control unit and adjusting the pressure table, the exhaust volume at the rectangular hole position can be controlled, thereby reducing gas fluctuation inside the tank and keeping the exhaust gas inflow within a suitable range, which in turn enhances the exhaust gas treatment function.

[0023] By installing the stripping unit, the waste in the exhaust gas is subjected to double stripping through stripping table A and stripping table B, which can further enhance the stripping function of the waste in the exhaust gas. The vertical back-and-forth movement of stripping table A and stripping table B can shake off the adsorbed waste, thereby preventing stripping table A and stripping table B from being blocked by waste, so as to ensure the air permeability of stripping table A and stripping table B and extend the service life of stripping table A and stripping table B.

[0024] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention.

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Reference Figures 1-13 This invention provides a vacuum sintering furnace for hammerhead processing, comprising a sintering furnace body 1, with a cooling and waste stripping module 2 installed on the outside of the sintering furnace body 1.

[0042] The cooling and waste stripping module 2 includes a split pipe 21 fixed to both sides of the sintering furnace body 1, a high-pressure blower 22 fixed to the upper part of the sintering furnace body 1, and a support frame A25 fixed to the outside of the sintering furnace body 1. Several round holes are reserved on the semi-circular surfaces of the pair of split pipes 21 that are close to each other. The exhaust end of the high-pressure blower 22 is connected to the top split pipe 21 through the connecting pipe A23. A cooling tank 26 is fixed to one side of the support frame A25. A condenser pipe 27 is fixed in the cooling tank 26. The upper end of the condenser pipe 27 is connected to the air inlet end of the high-pressure blower 22 through the connecting pipe B24. A cold air unit 28 is fixed to the upper end of the cooling tank 26. The cold air end and the air inlet end of the cold air unit 28 are respectively connected to the upper end and the lower end of the cooling tank 26.

[0043] The cooling and waste stripping module 2 also includes a support frame B212 fixed to the outside of the sintering furnace body 1. A tank 211 is fixed to one side of the support frame B212. The top of the tank 211 is an inverted funnel shape. An outflow channel 214 is fixed to the top of the tank 211. The outflow channel 214 is connected to the lower end of the condenser pipe 27. An inlet channel 219 is fixed to the bottom of the tank 211. One side of the bottom of the inlet channel 219 is connected to the bottom branch pipe 21 via a connecting pipe C29. The bottom of the inlet channel 219 is connected to a collection box 210. A box door is installed on the collection box 210. The collection box 210 is used to catch the waste falling from the inlet channel 219, thereby facilitating the collection of the waste stripped for the first time.

[0044] When the high-pressure blower 22 is activated, the exhaust gas after the internal parts of the tank 211 are removed is drawn into the condenser pipe 27 through the outlet channel 214. The cold air unit 28 sends the cold air to the cooling tank 26. The cold air quickly cools the hot air in the condenser pipe 27. After the cold air becomes hot, it returns to the cold air unit 28 for further cooling, ensuring the rapid cooling of the sintering furnace. The cooled exhaust gas is then sequentially sprayed into the sintering furnace body 1 through the connecting pipe B24, the high-pressure blower 22, the connecting pipe A23, and the top distribution pipe 21, thereby accelerating the cooling of the sintering furnace and greatly improving the processing efficiency of the sintering furnace.

[0045] A motor 218 is fixedly connected to the bottom of the outer side of the tank body 211. A connecting column 221 is fixedly connected to the rotating part of the motor 218. An assembly table 226 is fixedly connected to the inside of the tank body 211. An exchange unit is installed in the assembly table 226.

[0046] The replacement unit includes an assembly space 253 reserved in the assembly table 226. A bearing frame 229 is screwed onto the inner wall of the assembly space 253. A connecting ring 232 is fixed to the outer wall of the connecting column 221. A leak-proof ring 231 is fixed to the outer wall of the connecting ring 232. The two vertical sides of the leak-proof ring 231 are screwed onto the inner surface of the assembly space 253. The leak-proof ring 231 and the bearing frame 229 are fixedly connected.

[0047] An assembly opening 252 is reserved on the top outer wall of the support frame 229. An receiving opening 233 is reserved on the inner wall of the assembly opening 252. A beryllium copper sheet 234 is fixed to the top of the inner wall of the receiving opening 233. A stripping table C235 is engaged in the assembly opening 252. The stripping table C235 is made of porous carbon block. The outer wall of the stripping table C235 and the beryllium copper sheet 234 are in contact. A discharge groove 249 is reserved on the bottom outer wall of the assembly table 226.

[0048] The stripping table C235 has a triangular structure. There are multiple assembly ports 252 arranged circumferentially. A barrier ring 230 is screwed onto the outer wall of the connecting column 221. The outer wall of the barrier ring 230 is fixed to the assembly table 226. There are multiple receiving ports 233 and beryllium copper sheets 234 arranged in a mirror image. The beryllium copper sheets 234 are arched.

[0049] When the waste material in the exhaust gas inside the sintering furnace body 1 is stripped through the tank 211, the high-pressure blower 22 operates, drawing the exhaust gas sequentially through the bottom diversion pipe 21, connecting pipe C29, and inlet channel 219 into the tank 211. The tank 211 supports the assembly platform 226, and the exhaust gas moves from the bottom to the top of the tank 211. The motor 218 is powered on, and the motor 218 pulls the connecting column 221 to rotate. The blocking ring 230 blocks the flow between the assembly platform 226 and the connecting column 221. The connecting column 221, via the connecting ring 232, pulls the leak-proof ring 231 to rotate together. The leak-proof ring 231 is positioned inside the assembly platform 226 via the support frame 229. Rotation is performed within the assembly space 253. An assembly opening 252 pre-reserved on the wall of the support frame 229 is used to house the stripping table C235. A receiving opening 233 pre-reserved within the assembly opening 252 is used to assemble the beryllium copper sheet 234. The stripping table C235 is positioned within the assembly opening 252 under the deformation force of the beryllium copper sheet 234. Supported by the beryllium copper sheet 234, the support frame 229 can then pull the stripping table C235 to rotate together. The leak-proof ring 231 can rotate within the assembly space 253 to prevent leakage. After the exhaust gas enters the assembly space 253, it exits through the stripping table C235 and passes through the stripping table C23... 5. The waste material in the exhaust gas is stripped. During the stripping process, the support frame 229, via the beryllium copper sheet 234, pulls multiple circumferentially arranged stripping tables C235 to rotate continuously within the assembly space 253. As the waste material accumulates on the stripping tables C235, the stripping function of the tables gradually weakens and they become heavier. When the resistance between the beryllium copper sheet 234 and the stripping tables C235 is less than the total weight of the stripping tables C235 and the waste material inside them, the stripping tables C235 move downwards along the inside of the assembly opening 252. At this moment, the bottom of the stripping tables C235 will rotate and touch the bottom of the inner wall of the assembly space 253. When 235 moves to the position of discharge tank 249, it falls from the position of discharge tank 249 under the combined weight of the stripping table C235 and the waste, thereby achieving the self-disintegration of the stripping table C235. Through the installed replacement unit, the stripping function of the stripping table C235 is monitored by changing the total weight of the stripping table C235, so that the stripping table C235 with weaker stripping function can be disintegrated, thereby allowing the stripping table C235 to maintain a strong stripping function, ensuring the stripping of waste in the exhaust gas. Furthermore, by installing multiple stripping tables C235 and performing individual replacement of the stripping table C235, the stripping function of the stripping table C235 can be guaranteed.

[0050] Reference Figure 7 and Figure 8The outer wall of the tank 211 has a pre-reserved inlet 215, and the inside of the tank 211 has a pre-reserved leak-proof outlet 251. The leak-proof outlet 251 is connected to the inside of the inlet 215. A sealing plate 216 is movably installed in the leak-proof outlet 251. The sealing plate 216 is arched. A barrier plate 217 is fixedly connected to the upper wall of the sealing plate 216. A through-hole A227 is pre-reserved on the top outer wall of the assembly platform 226. The bottom of the through-hole A227 is connected to the inside of the assembly space 253.

[0051] After the stripping table C235 becomes heavy and falls from inside the assembly table 226, a new stripping table C235 needs to be installed into this empty space. At this moment, the worker pushes the sealing plate 216 upward from inside the leak-proof port 251 through the barrier plate 217, opening the feeding port 215 through the sealing plate 216. Then, the new stripping table C235 is placed into the tank 211 through the feeding port 215, and then the stripping table C235 is placed on the wall of the support frame 229 through the through port A227. In the assembly port 252, the stripping table C235 is quickly replaced. Then, the sealing plate 216 moves downward along the leak-proof port 251 with the barrier plate 217 and the free fall. The sealing plate 216 seals the inlet port 215, thereby preventing the exhaust gas in the tank 211 from overflowing from the inlet port 215. After being stripped by the stripping table C235 in the assembly space 253, the exhaust gas moves upward from the through port A227 at the top of the assembly table 226.

[0052] Reference Figure 7 and Figure 9 The bottom of the assembly platform 226 is equipped with an unloading unit, which includes a dividing plate 248 fixedly connected to the bottom of the inner wall of the tank 211. A through-hole B228 is reserved on the outer wall of the bottom of the assembly platform 226. The bottom of the through-hole A227 is directly opposite the top of the through-hole B228. The outer wall of the top of the dividing plate 248 is fixedly connected to the bottom of the assembly platform 226. A discharge groove 249 is reserved between the pair of dividing plates 248 on the outer wall of the bottom of the assembly platform 226.

[0053] A deformable component B245 is fixedly connected to the bottom of the inner wall of the can 211. The deformable component B245 is made of spiral beryllium copper wire. The top of the deformable component B245 is fixedly connected to the support platform 244. The bottom of the support platform 244 is fixedly connected to the bonding platform A246. The bottom inside the can 211 is fixedly connected to the bonding platform B247. The bonding platform A246 is directly opposite the bonding platform B247. Both the bonding platform A246 and the bonding platform B247 are made of copper sheets. A removal port 213 is reserved on the outer wall of the can 211. A buzzer is fixedly connected to the outer side of the top of the can 211. The bonding platform A246 is electrically connected to an external power source. The bonding platform B247 is electrically connected to the buzzer.

[0054] The dividing plate 248 is located between the assembly platform 226 and the bottom of the inner wall of the tank 211. A pair of dividing plates 248 assist the assembly platform 226 in forming a closed chamber inside the tank 211. The top of the dividing plate 248 and the bottom of the support frame 229 rotate and touch, thus preventing leakage between the dividing plate 248 and the support frame 229. Exhaust gas flows into the assembly space 253 through the through port B228. When the total weight of the stripping table C235 and the waste is sufficient to fall from the discharge trough 249, the stripping table C235 falls onto the top of the support platform 244. The tank 211 supports the support platform 244 via the deformable element B245. The support platform 244 is positioned on the stripping table C235. Under the pressure of 5, the deformable part B245 shortens. During the downward movement of the support platform 244, the bonding platform A246 is pulled downward together, causing the bonding platforms A246 and B247 to touch each other. When the bonding platforms A246 and B247 touch, the power of the buzzer is turned on. At this moment, the buzzer sounds to warn the staff to remove the fallen stripping platform C235 through the pick-up port 213 and replace it with a new stripping platform C235 to ensure the normal operation of the device. The installed unloading unit warns the staff to replace the new stripping platform C235 on time to ensure the ease of use and sensitivity of the device, and to ensure the function of stripping waste materials in the exhaust gas.

[0055] Reference Figure 7 , Figure 9 and Figure 11 A control unit is installed at the bottom of the inner surface of the tank 211. The control unit includes a connecting shell 236 fixedly connected to the bottom of the inner wall of the tank 211. The connecting shell 236 is positioned opposite the access channel 219. A rectangular hole 237 is reserved on the peripheral wall of the connecting shell 236. Multiple rectangular holes 237 are provided and arranged circumferentially. A peeling piece 243 is fixedly connected to the inner wall of the connecting shell 236.

[0056] The top of the peeling plate 243 is fixedly connected to the movable column 238. The movable ring 239 is movably installed on the outer peripheral wall of the movable column 238. The bottom of the movable ring 239 is fixedly connected to the pressure ring 240, which is circular. The outer peripheral wall of the movable ring 239 is fixedly connected to the pressure platform 241. The top of the pressure platform 241 is fixedly connected to the deformable part A242. The top of the deformable part A242 is fixedly connected to the top inside the connecting shell 236.

[0057] To address the potential instability of exhaust gas during its delivery and ensure effective exhaust gas treatment, a control unit is installed to maintain the exhaust gas flow within a suitable range. When the exhaust gas is delivered to the tank 211 via the inlet channel 219, it passes through the stripping plate 243 and moves into the connecting shell 236. The stripping plate 243 strips larger solids within the exhaust gas, preventing them from clogging the stripping platform C235. After reaching the stripping plate 243, the exhaust gas flows through the rectangular hole 237 on the connecting shell 236 into the tank 211. The deformable element A242 supports the pressure platform 241, and the pressure platform 241 can block the rectangular hole 237 on the connecting shell 236. The exhaust gas compresses the pressure platform 241, causing it to drive the changing ring 239 to move along the changing column 238. The changing column 238, via the changing ring 239, guides and supports the pressure platform 241, allowing it to... Vertically stable movement occurs when the amount of exhaust gas entering increases. Under the pressure of the exhaust gas, the pressure table 241 moves upward. The deformation element A242 provides impact reduction to the pressure table 241. With the cooperation of the deformation element A242, the upward movement stroke of the pressure table 241 can be reduced. The movement of the pressure table 241 can regulate the exhaust volume at the position of the rectangular hole 237, thereby reducing the gas floating inside the tank 211 and keeping the exhaust gas inflow within a suitable range. This further enhances the exhaust gas treatment function. When the exhaust gas inflow is too small, the pressure table 241 and the changing ring 239 move downward under their own weight. The changing ring 239 pulls the pressure ring 240 downward together. During the downward movement, the pressure ring 240 will contact the top of the peeling plate 243. The pressure ring 240 strikes the peeling plate 243, thereby removing larger solids on the peeling plate 243 and ensuring the peeling function of the peeling plate 243.

[0058] Reference Figure 7 and Figure 10 Inside the tank 211, a stripping unit is installed. The stripping unit includes a movable platform 220 that is fixedly connected to the inner wall of the tank 211. A stripping platform A222 is movably installed in the movable platform 220. The stripping platform A222 is made of porous carbon block. The bottom of the stripping platform A222 is fixedly connected to a stripping platform B223, which is also made of porous carbon block. A connecting column 221 passes through the stripping platform A222 and the stripping platform B223.

[0059] The bottom of the stripping table B223 has a reserved opening 250. The inner surface of the opening 250 is fixed to the guide table 225, which is coiled in the opening 250. The outer wall of the connecting column 221 is fixed to the bending strip 224, which is a right-angle folded ruler. The top of the bending strip 224 slides and fits against the outer surface of the bottom wall of the guide table 225.

[0060] After being stripped by the stripping table C235, the exhaust gas continues to rise, and the waste in the exhaust gas undergoes double stripping via stripping tables A222 and B223, further enhancing the stripping function. The tank body 211 provides movable support for the stripping table A222 via the rotating platform 220. The stripping table B223 at the bottom of the stripping table A222 expands the contact area between the stripping table and the exhaust gas, further enhancing the stripping function. The stripping table B223 supports the guide platform 225 via the rotating port 250. During rotation, the connecting column 221 pulls the bending strip 224 to rotate together. During rotation, the bending strip 224 flexibly adheres to the bottom of the guide platform 225. The guide platform 225 is coiled within the rotating port 250, and... The guide platform 225 raises the stripping platform B223 and the stripping platform A222, allowing the stripping platform A222 to move upwards in the moving platform 220. After the bending strip 224 and the guide platform 225 separate, the stripping platform A222 and the stripping platform B223 move downwards under their own weight. The vertical back-and-forth movement of the stripping platform A222 and the stripping platform B223 can shake off the adsorbed waste, thereby preventing the stripping platform A222 and the stripping platform B223 from being blocked by waste, so as to ensure the air permeability of the stripping platform A222 and the stripping platform B223 and extend the service life of the stripping platform A222 and the stripping platform B223. Through further stripping, the exhaust gas flows from the outflow channel 214 at the top of the tank 211 to the condenser pipe 27.

[0061] The specific implementation method is as follows: During cooling, when stripping waste materials from the exhaust gas, the high-pressure blower 22 operates, drawing the exhaust gas sequentially through the bottom branch pipe 21, connecting pipe C29, and inlet channel 219 into the connecting shell 236. The stripping plates 243 then strip larger solids from the exhaust gas. The exhaust gas compresses the pressure table 241, causing it to pull the moving ring 239 along the moving column 238. The movement of the pressure table 241 regulates the air intake at the rectangular hole 237, thereby reducing gas buoyancy inside the tank 211. The exhaust gas flows through the through-hole B228 to the assembly space 25. In step 3, the waste in the exhaust gas is stripped by the stripping table C235. The support frame 229 pulls multiple circumferentially arranged stripping tables C235 to rotate continuously in the assembly space 253 via the beryllium copper sheet 234. With the cooperation of the stripping table C235 and the total weight of the waste, it falls out from the position of the discharge tank 249, which facilitates the self-disintegration of the stripping table C235 with weaker stripping function. The exhaust gas is stripped again by the stripping table A222 and the stripping table B223. The vertical back and forth movement of the stripping table A222 and the stripping table B223 can shake off the adsorbed waste, thereby increasing the service life of the stripping table A222 and the stripping table B223.

[0062] After stripping, the exhaust gas is drawn into the condenser tube 27 through the outlet channel 214. The cold air unit 28 sends the cold air to the cooling tank 26. The cold air quickly cools the hot gas in the condenser tube 27. After the cold air becomes hot, it returns to the cold air unit 28 for cooling, ensuring the rapid cooling of the sintering furnace. The cooled exhaust gas is then sprayed into the sintering furnace body 1 through the connecting pipe B24, the high-pressure blower 22, the connecting pipe A23, and the top distribution pipe 21 in sequence, thereby accelerating the cooling of the sintering furnace and greatly improving the processing efficiency of the sintering furnace.

[0063] Subsequently, during the cooling process of the sintering furnace, the waste generated during sintering is also removed to ensure the cleanliness of the sintering furnace interior.
