Description

Technical Field

[0001] This utility model relates to the technical field of spinneret cleaning, and in particular to a vacuum furnace for spinneret cleaning. Background Technology

[0002] The spinneret is a crucial component in fiber manufacturing, especially in melt spinning and solution spinning processes. It is a metal plate or tubular structure with multiple tiny holes used to extrude polymer melts or solutions into filaments.

[0003] After a certain period of use, the spinneret needs to be replaced to clean the spinning residue accumulated in the tiny pores. Currently, the most effective cleaning method is to place the spinneret in a vacuum combustion furnace to burn it, ensuring that the spinning residue inside the spinneret is completely removed.

[0004] However, existing vacuum combustion furnaces directly discharge the exhaust gas generated after the spinneret combustion into the exhaust gas treatment tower. This method has the following problems: the exhaust gas temperature generated by the vacuum combustion furnace is between 400℃ and 800℃, which is quite high. To avoid damage to the internal structure of the exhaust gas treatment tower due to excessive temperature, it is often necessary to increase the length of the exhaust gas pipeline to allow the exhaust gas to be sufficiently cooled before flowing into the exhaust gas treatment tower. However, increasing the pipeline length significantly increases the load pressure on the blower and also significantly increases the floor space required. Therefore, to solve the above problems, a spinneret cleaning vacuum furnace that can rapidly cool the combustion exhaust gas has been proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a vacuum furnace for cleaning spinnerets that can quickly cool down exhaust gas.

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] like Figures 1 to 3As shown, a spinneret cleaning vacuum furnace 10 includes a combustion furnace 100 and a mixing assembly 200. The mixing assembly 200 includes a mixing tank 210, a mixing component 220, a water tank 230, and a pump 240. A mixing chamber 211 is provided inside the mixing tank 210. An air inlet pipe 251 and a water inlet pipe 252 are respectively provided on opposite sides of the mixing tank 210. A discharge pipe 253 is also provided at the bottom of the mixing tank 210. The air inlet pipe 251, the water inlet pipe 252, and the discharge pipe 253 are all connected to the mixing chamber 211. The air inlet pipe 251 is connected to the combustion furnace 100. The water inlet pipe 252 is used to connect to an external water supply pipe. The mixing component 220 is disposed in the mixing chamber 211. One side of the mixing component 220 is aligned with the air inlet pipe 251. The water inlet pipe 252 is located above the mixing component 220. The pump 240 is connected to the discharge pipe 253 and the water tank 230 respectively.

[0030] It should be noted that the air inlet pipe 251 is connected to the combustion furnace 100 via a pipeline. The exhaust pipe 253 is connected to the suction pump 240 via a pipeline. The suction pump 240 is connected to the water tank 230 via a pipeline. Thus, water is injected into the mixing chamber 211 through the water inlet pipe 252, and the water drips down from the top of the mixing element 220. When the exhaust gas generated by the combustion spinneret in the combustion furnace 100 enters the mixing chamber 211 through the air inlet pipe 251, the exhaust gas comes into contact with the mixing element 220. Since the mixing element 220 is in a wet state, the exhaust gas and the mixing element 220 are in full contact, allowing the temperature of the exhaust gas to be transferred to the water through the mixing element 220. Then, the water enters the water tank 230 under the suction of the suction pump 240. Finally, the wastewater in the water tank 230 is transported to the wastewater treatment workshop, while the exhaust gas that has been cooled in the water tank 230 flows into the waste gas treatment tower for filtration treatment. Thus, the spinneret cleaning vacuum furnace 10 of this application can quickly transfer the temperature of the exhaust gas to the water medium. It should be noted that the wastewater in the water tank 230 can be directly injected into the water inlet pipe 252 after filtration, thereby realizing the recycling of wastewater and greatly saving the amount of clean water used. In one embodiment, the recycled wastewater can be replaced periodically, thereby effectively saving the cost of clean water.

[0031] like Figure 1 As shown, in one embodiment, an exhaust pipe 261 is provided on the top of the water tank 230, and the exhaust pipe 261 is used to communicate with the waste gas treatment tower.

[0032] It should be noted that the pump 240 discharges wastewater from the top of the water tank 230 into the water tank 230, so that the wastewater remains in the water tank 230, while the exhaust gas can be discharged into the exhaust gas treatment tower for treatment through the exhaust pipe 261.

[0033] like Figure 1As shown, in one embodiment, a wastewater pipe 262 is also provided at the bottom of the water tank 230. It should be noted that the wastewater pipe 262 can be directly connected to the inlet pipe 252 via a water pump, thus realizing the recycling of cooling wastewater. In another embodiment, the wastewater pipe 262 can also be connected to a wastewater treatment workshop.

[0034] like Figures 1 to 3 As shown, in one embodiment, the mixing tank 210 includes a tank body 212 and a tank lid 213. The tank lid 213 is detachably fastened to the tank body 212 so that the tank lid 213 and the tank body 212 together form a mixing chamber 211.

[0035] It should be noted that, in order to facilitate the installation of the mixing component 220 inside the mixing chamber 211, the mixing tank 210 is configured with a structure in which the tank body 212 and the tank cover 213 are fastened together. Specifically, the air inlet pipe 251, the water inlet pipe 252, and the discharge pipe 253 are all located on the tank body 212.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the mixing tank 210 further includes a crossbar 214, a screw 215, and two retaining rings 216. The two retaining rings 216 are respectively rotatably disposed on opposite sides of the tank body 212. The two ends of the crossbar 214 are respectively fastened to the two retaining rings 216. The screw 215 is screwed to the crossbar 214, and one end of the screw 215 is abutted against the tank cover 213. The screw 215 is used to push the tank cover 213 to seal the tank body 212.

[0037] It should be noted that a protruding lug is provided on the outer wall of the barrel 212 at an opposing position. Two buckles 216 pass through the two protruding lugs, allowing the buckles 216 to rotate relative to the barrel 212. Then, after the two ends of the crossbar 214 are engaged with the two buckles 216 respectively, the screw 215 is rotated so that one end of the screw 215 abuts against the barrel lid 213. Thus, as the screw 215 rotates under force, the two buckles 216 are tightened, thereby ensuring that the barrel lid 213 is tightly fastened to the opening of the barrel 212.

[0038] like Figure 2 As shown, in one embodiment, a slot 2141 is provided on the end of the crossbar 214, and a buckle 216 is fastened in the slot 2141.

[0039] Thus, the slot 2141 can secure the buckle 216, preventing the buckle 216 from slipping off the crossbar 214, and ensuring that the lid 213 and the barrel body 212 are reliably fastened together.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, a positioning ring 217 is provided on the top of the bucket lid 213, and the end of the screw 215 is accommodated in the positioning ring 217.

[0041] In this way, the positioning ring 217 is used to limit the screw 215, ensuring that the screw 215 is always reliably abutting the middle position of the bucket lid 213 during the rotation under force, thereby ensuring that the bucket lid 213 and the bucket body 212 are reliably fastened and fixed.

[0042] like Figure 3 As shown, in one embodiment, a sealing ring 218 is provided on the open end face of the barrel body 212, and the barrel lid 213 abuts against the sealing ring 218.

[0043] It should be noted that, in order to avoid poor sealing between the lid 213 and the body 212, a sealing ring 218 is installed on the open end face of the body 212. When the lid 213 and the body 212 are fastened together, the lid 213 and the sealing ring 218 are tightly abutted together.

[0044] like Figure 3 As shown, in one embodiment, a bearing step 219 is provided on the inner side wall of the barrel 212, and the mixing component 220 is disposed on the bearing step 219.

[0045] Thus, the mixing component 220 is supported by the supporting step 219, so that the mixing component 220 is suspended in the mixing chamber 211, allowing the exhaust gas flowing into the intake pipe 251 to better contact the water flowing on the mixing component 220 and quickly cool down the exhaust gas.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the mixing component 220 includes a top ring 221, a mesh body 222, and a plurality of vertical rods 223. The top ring 221 abuts against the bearing step 219, the mesh body 222 is disposed on the inner side wall of the top ring 221, and one end of each vertical rod 223 is disposed at intervals on the mesh body 222, so that each vertical rod 223 is distributed in the vertical direction within the barrel 212.

[0047] It should be noted that, in one embodiment, the mixing component 220 is a metal structure formed by welding together a top ring 221, a mesh body 222, and several vertical rods 223. The water inlet pipe 252 is located above the mesh body 222, and water from the water inlet pipe 252 flows down from the mesh body 222 through each vertical rod 223. Exhaust gas from the air inlet pipe 251 is blown laterally towards each vertical rod 223. This allows the exhaust gas to rapidly transfer heat with the water through each vertical rod 223.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
