Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial manufacturing technology, and in particular to an inert gas heating mechanism for a degreasing machine. Background Technology
[0002] Inert gases, such as helium, argon, and neon, have stable atomic structures and high melting and boiling points. They exhibit inert properties in chemical reactions and are not easily reacted with other substances. This stability means that when inert gases are released into the atmosphere, they do not pose a direct threat to human health or the environment. In certain degreasing processes, such as the degreasing step in metal injection molding, heating with inert gases can provide a stable and oxygen-free environment, which is beneficial for the volatilization of binders and the degreasing process. In addition, inert gases can also help remove gases generated during the degreasing process, thereby further improving degreasing efficiency.
[0003] During the degreasing process, grease easily evaporates into the air under high temperature and chemical degreasing agents, forming exhaust gas containing grease particles. In addition, some solid impurities and particulate matter may also be generated during the degreasing process. These particulate matter may include oil mist, dust and other solid impurities. Existing degreasing facilities are often unable to absorb and treat the solid impurities and particulate matter in the exhaust gas, which are released into the air and pose a health hazard to workers. Utility Model Content
[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0005] Specifically, the technical problem to be solved by this utility model is to provide an inert gas heating mechanism for a degreasing machine, so as to solve the problem that during the degreasing process, grease is easily volatilized into the air under the action of high temperature and chemical degreasing agents, forming exhaust gas containing grease particles. In addition, some solid impurities and particulate matter may also be generated during the degreasing process. These particulate matter may include oil mist, dust and other solid impurities. Existing degreasing mechanisms are often unable to absorb and treat the solid impurities and particulate matter in the exhaust gas, which are discharged into the air and cause harm to the health of workers.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0007] An inert gas heating mechanism for a degreasing machine includes an inert gas storage tank. A first vent pipe is connected to the outer wall of the storage tank. The outlet of the first vent pipe is connected to a superheater. A second vent pipe is connected to the outer wall of the superheater. A furnace body is located at the outlet of the second vent pipe. A third vent pipe is connected to the outer wall of the furnace body. A dust removal assembly is located at the outlet of the third vent pipe. The dust removal assembly includes a dust removal canister located at the outlet of the third vent pipe. A water distribution pipe is located on the inner wall of the dust removal canister. Multiple sets of spray nozzles are evenly connected to the outer wall of the water distribution pipe. The dust collector has a motor at its upper end, a shaft at its output end, and multiple sets of stirring blades arranged in a ring from top to bottom on the outer wall of the shaft. A water outlet is fixed at the lower end of the dust collector. A fourth vent pipe is connected to the upper outer wall of the dust collector, and a filter assembly is provided at the outlet end of the fourth vent pipe. A fifth vent pipe is connected to one side of the outer wall of the superheater, and a saturated steam generating device is provided at the end of the fifth vent pipe furthest from the superheater. A water tank is provided on one side of the outer wall of the dust collector assembly, and a water pump is connected to one side of the water tank. A water pipe is provided at the outlet end of the water pump.
[0008] As an improved technical solution, the first vent pipe is provided with a first vent valve at its upper end, the second vent pipe is provided with a second vent valve at its upper end, the third vent pipe is provided with a third vent valve at its upper end, and the fifth vent pipe is provided with a fourth vent valve at its upper end.
[0009] As an improved technical solution, the water outlet of the water pipe passes through the outer wall of the dust collector and is connected to the water distribution pipe.
[0010] As an improved technical solution, the water distribution pipe is configured as a ring structure from top to bottom, and the nozzles are evenly distributed in a ring at the upper end of the water distribution pipe.
[0011] As an improved technical solution, the filter assembly includes a filter box located at the outlet end of the fourth vent pipe, and three sets of activated carbon plates are movably inserted into the upper end of the filter box, with the outer wall of the activated carbon plates and the inner wall of the filter box being in contact.
[0012] As an improved technical solution, the activated carbon plate is fixedly fitted with a sealing gasket on the upper outer wall of the filter box.
[0013] As an improved technical solution, an air outlet pipe is connected to one side of the outer wall of the filter box.
[0014] After adopting the above technical solution, the beneficial effects of this utility model are:
[0015] 1. In this utility model, the waste gas generated during the degreasing reaction enters the dust collection tank through the third vent pipe. The water pump and motor are started, and the water pump guides the water in the water tank into the water distribution pipe through the water inlet pipe and sprays it out through the nozzle. The motor drives the rotating shaft to rotate at high speed, and the rotating shaft drives the stirring blade to rotate at high speed. The high-speed rotation of the stirring blade prevents larger impurities in the waste gas from rising continuously, and they fall to the bottom of the dust collection tank along with the water flow sprayed from the nozzle, and are finally discharged through the outlet. This solves the problem that existing degreasing mechanisms often cannot absorb and treat solid impurities and particulate matter in waste gas.
[0016] 2. This utility model, the device achieves efficient heating and degreasing of the degreased material by combining inert gas preheating and superheated steam degreasing. The use of inert gas avoids the degreased material from reacting with oxygen in the air, thereby reducing safety risks such as fire. Attached Figure Description

[0026] like Figure 1 As shown, this embodiment provides an inert gas heating mechanism for a degreasing machine, including an inert gas storage tank 1, a first vent pipe 2 connected to the outer wall of the inert gas storage tank 1, a superheater 3 connected to the outlet end of the first vent pipe 2, a second vent pipe 4 connected to the outer wall of the superheater 3, a furnace body 5 provided at the outlet end of the second vent pipe 4, a fifth vent pipe 10 connected to one side of the outer wall of the superheater 3, a saturated steam generating device 11 provided at the end of the fifth vent pipe 10 away from the superheater 3, a water tank 16 provided on one side of the outer wall of the dust removal assembly 7, a water pump 17 connected to one side of the water tank 16, and a water pipe 18 provided at the outlet end of the water pump 17.
[0027] The first vent pipe 2 is equipped with a first vent valve 12 at its upper end, the second vent pipe 4 is equipped with a second vent valve 13 at its upper end, the third vent pipe 6 is equipped with a third vent valve 14 at its upper end, and the fifth vent pipe 10 is equipped with a fourth vent valve 15 at its upper end.
[0028] Inert gas storage tank 1 provides inert gases, such as nitrogen or argon, for heating and degreasing. These gases maintain chemical stability during heating, preventing reactions with the degreased material. Furnace body 5 provides space to hold the degreased material. The object to be degreased is placed inside furnace body 5. Then, the fourth vent valve 15 is closed, and the first vent valve 12, second vent valve 13, and third vent valve 14 are opened. The inert gas from inert gas storage tank 1 enters superheater 3 through first vent pipe 2. Superheater 3 is started, and after heating the inert gas to a certain temperature, it is sent into furnace body 5 through second vent pipe 4. Inside furnace body 5, the inert gas exchanges heat with the degreased material, gradually raising its temperature to the predetermined level. This step helps prevent condensation problems caused by temperature differences during subsequent degreasing. After preheating, the supply of inert gas to superheater 3 is stopped. Gas is introduced, the first vent valve 12 is closed, the fourth vent valve 15 is opened, and the saturated steam generating device 11 is started. This device heats the liquid to generate saturated steam, which is then sent to the superheater 3 to be heated into superheated steam. The superheated steam has a high heat capacity and thermal conductivity, which can rapidly increase the temperature inside the furnace body 5 and achieve effective degreasing of the degreased material. After degreasing is completed, the fourth vent valve 15 and the saturated steam generating device 11 are closed, and the generation and supply of superheated steam are stopped. The temperature inside the furnace body 5 gradually decreases, and the degreased material also cools down. After the temperature drops to a safe range, the degreased material can be taken out of the furnace body 5 for subsequent processing. By combining inert gas preheating and superheated steam degreasing, efficient heating and degreasing of the degreased material are achieved. The use of inert gas avoids the degreased material from reacting with oxygen in the air, thereby reducing safety risks such as fire.
[0029] like Figures 1-3 As shown, the third vent pipe 6 is equipped with a dust removal component 7 at its outlet. The dust removal component 7 includes a dust removal tank 71 located at the outlet of the third vent pipe 6. The inner wall of the dust removal tank 71 is provided with a water distribution pipe 72. Multiple sets of nozzles 73 are evenly connected to the outer wall of the water distribution pipe 72. A motor 74 is provided at the upper end of the dust removal tank 71. A rotating shaft 75 is provided at the output end of the motor 74. Multiple sets of stirring blades 76 are arranged in a ring from top to bottom on the outer wall of the rotating shaft 75. A water outlet 77 is fixedly provided at the lower end of the dust removal tank 71. A fourth vent pipe 8 is connected to the upper outer wall of the dust removal tank 71. The outlet of the fourth vent pipe 8 is provided with a... The filter assembly 9 has a water pipe 18 whose outlet end passes through the outer wall of the dust collector 71 and is connected to the water distribution pipe 72. The water distribution pipe 72 is arranged in a ring shape from top to bottom. The nozzles 73 are evenly distributed in a ring shape on the upper end of the water distribution pipe 72. The filter assembly 9 includes a filter box 91 located at the air outlet of the fourth air pipe 8. Three sets of activated carbon plates 92 are movably inserted into the upper end of the filter box 91. The outer wall of the activated carbon plates 92 is attached to the inner wall of the filter box 91. The activated carbon plates 92 are fixedly fitted with a sealing gasket 93 on the upper outer wall of the filter box 91. An air outlet pipe 94 is connected to one side of the outer wall of the filter box 91.
[0030] The exhaust gas generated during the degreasing reaction enters the dust collection tank 71 through the third vent pipe 6. This exhaust gas contains large impurities, primarily particulate matter, oil mist, and dust. These impurities mainly originate from the chemical degreasing agents used in the degreasing process, grease, and contaminants on the surface of the treated materials. The water pump 17 and motor 74 are started. The water pump 17 guides water from the water tank 16 through the water pipe 18 into the water distribution pipe 72, and sprays it out through the nozzle 73. The motor 74 drives the rotating shaft 75 to rotate at high speed, which in turn drives the stirring blades 76 to rotate at high speed. The high-speed rotation of the stirring blades 76 prevents larger impurities in the exhaust gas from continuously rising, and... The water sprayed from nozzle 73 falls to the bottom of dust collection tank 71 and is finally discharged through outlet 77. The waste gas, after removing impurities, enters the filter box 91 through the fourth vent pipe 8 and is absorbed by the activated carbon plate 92. The purified gas is discharged into the air through the vent pipe 94. The sealing gasket 93 increases the airtightness between the activated carbon plate 92 and the filter box 91, preventing unpurified waste gas from being discharged from the top of the filter box 91. When the activated carbon plate 92 needs to be replaced or maintained, it can be pulled out from the inner wall of the filter box 91 along the filter box 91 for easy replacement and maintenance.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
