Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of quenching oil tanks, in particular to an environmental protection device for quenching oil tanks. Background Art
[0002] Quenching is a heat treatment process in which steel is heated to above the critical temperature, kept at this temperature for a certain period of time, and then cooled at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite.
[0003] Existing workpieces generate smoke during quenching, which can pollute the surrounding environment. Currently, to prevent smoke from spreading and causing pollution, smoke hoods are often used to extract the smoke, which is then treated with a treatment agent to remove harmful impurities. However, in actual implementation, the smoke is directly introduced into the treatment agent for treatment, resulting in a short treatment time for the smoke, resulting in poor treatment results. Therefore, we propose an environmental protection device for quenching oil tanks. Utility Model Content
[0004] The purpose of the utility model is to provide an environmental protection device for a quenching oil tank, which solves the problems raised in the background technology.

[0006] An exhaust fan and a treatment box are fixed on the upper and lower sides of the other side wall of the support plate respectively. One end of the exhaust fan is connected to the smoke hood through a hose. Staggered guide plates are fixed on both side walls of the inner cavity of the treatment box. A duct is fixed on the other end of the exhaust fan. The tail end of the duct passes through the top of the treatment box and the guide plate, and the tail end of the duct is placed on the lower side of the inner cavity of the treatment box. An air outlet pipe is fixed on one side of the top of the treatment box.
[0007] By adopting the above technical solution, the treatment agent is first introduced into the inner cavity of the treatment box, and the treatment agent is made to submerge the guide plate at the highest point. Then, during the quenching process, the air is exhausted by the exhaust fan, and the smoke generated is collected by the smoke hood, and then introduced into the inner cavity of the treatment box. The smoke is treated with the treatment agent in the treatment box. At the same time, the gas can be redirected by the guide plate during the upward movement, thereby slowing down the gas flow speed, thereby extending the treatment time, and thus helping to improve the treatment effect of the smoke.
[0008] As a preferred embodiment of the present invention, a plurality of evenly distributed and staggered short columns are fixed to the bottom of the guide plate.
[0009] By adopting the above technical solution, when the guide plate guides the gas, the gas moving in the water will impact the short columns staggered at the bottom of the guide plate, thereby redirecting the gas and the treatment agent, which is beneficial to further improve the contact treatment effect between the smoke gas and the treatment agent, and further improve the effect of removing harmful impurities.
[0010] As a preferred embodiment of the present invention, a limiting groove is provided on one side wall of the support plate, an adaptive limiting slider is inserted into the inner cavity of the limiting groove, an electric push rod is fixed to the bottom of the limiting slider, and the tail end of the electric push rod is fixed to the bottom of the inner cavity of the limiting groove.
[0011] By adopting the above technical solution, the fume hood can be driven to rise and fall by the electric push rod, thereby avoiding obstacles when placing the workpiece. At the same time, the fume hood is lowered during processing to maximize the proximity to the oil tank, which is beneficial to improving the effect of smoke extraction.
[0012] As a preferred embodiment of the present invention, an activated carbon filter screen and a high-efficiency HEPA filter screen are fixed on the upper side of the inner cavity of the treatment box.
[0013] By adopting the above technical solution, the treated gas can be adsorbed again, thereby further improving the treatment effect of the smoke.
[0014] As a preferred embodiment of the present invention, the top opening of the processing box is provided with a feed port and an end cover is inserted into the feed port, and a discharge valve is fixedly connected to the lower side of one side wall of the processing box.
[0015] By adopting the above technical solution, it is convenient to add the treatment agent and also convenient to export the used treatment agent.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] The environmental protection device for a quenching oil tank according to the technical solution of the present application extracts smoke by suction and introduces it into a treatment agent for treatment. During the treatment process, staggered guide plates are used to guide the direction of gas movement, thereby slowing the speed at which the gas moves upward in the treatment agent, thereby extending the treatment time and thereby improving the treatment effect of harmful impurities in the smoke.
[0018] When the guide plate guides the gas, the gas moving in the water will impact the short columns staggered at the bottom of the guide plate, thereby redirecting the gas and the treatment agent, which is beneficial to further improve the contact treatment effect between the smoke gas and the treatment agent, and further improve the effect of removing harmful impurities;
[0019] The fume hood can be raised and lowered by an electric push rod, thereby avoiding obstacles when placing the workpiece. At the same time, the fume hood is lowered during processing to maximize its proximity to the oil tank, which is beneficial to improving the effect of smoke extraction.

[0029] An exhaust fan 15 and a processing box 2 are fixed to the upper and lower sides of the other side wall of the support plate 11, respectively. One end of the exhaust fan 15 is connected to the smoke hood 12 through a hose. Staggered guide plates 23 are fixed to both side walls of the inner cavity of the processing box 2. A conduit is fixed to the other end of the exhaust fan 15. The tail end of the conduit passes through the top of the processing box 2 and the guide plate 23 and is placed on the lower side of the inner cavity of the processing box 2. An air outlet pipe 21 is fixed to one side of the top of the processing box 2.
[0030] In actual use, the treatment agent is first introduced into the inner cavity of the treatment box 2, and the treatment agent is made to cover the highest guide plate 23. Then, during the quenching process, the exhaust fan 15 is used to exhaust the air, and the smoke generated is collected by the smoke hood 12, and then introduced into the inner cavity of the treatment box 2. The smoke is treated with the treatment agent in the treatment box 2. At the same time, the gas can be redirected by the guide plate 23 during the upward movement, thereby slowing down the gas flow speed, thereby extending the treatment time, and thus helping to improve the treatment effect of the smoke.
[0031] Furthermore, the top opening of the processing box 2 is provided with a feed port and an end cover is inserted into the feed port, and the lower side of one side wall of the processing box 2 is fixedly connected to a discharge valve 22, so that it is convenient to add the treatment agent and also convenient to discharge the used treatment agent.
[0032] Furthermore, an activated carbon filter panel 25 and a high-efficiency HEPA filter panel 26 are fixed on the upper side of the inner cavity of the treatment box 2, which can re-adsorb the treated gas and further improve the treatment effect of the smoke.
[0033] like Figure 1 and 3 4; a plurality of evenly distributed and staggered short columns 24 are fixed to the bottom of the guide plate 23. In the process of guiding the gas through the guide plate 23, the gas moving in the water will impact the staggered short columns 24 at the bottom of the guide plate 23, thereby redirecting the gas and the treatment agent, which is beneficial to further enhance the contact treatment effect of the smoke gas and the treatment agent, and further enhance the effect of removing harmful impurities.
[0034] like Figure 1 and 2 As shown; a limit chute is provided on one side wall of the support plate 11, a matching limit slider 13 is inserted into the inner cavity of the limit chute, an electric push rod 14 is fixed to the bottom of the limit slider 13, and the tail end of the electric push rod 14 is fixed to the bottom of the inner cavity of the limit chute;
[0035] The electric push rod 14 can drive the smoke hood 12 to rise and fall, thereby avoiding obstacles when placing the workpiece. At the same time, the smoke hood 12 is lowered during processing to maximize its proximity to the oil tank 16, which is beneficial to improving the effect of smoke extraction.
[0036] The implementation principle of the environmental protection device for a quenching oil tank in the present application is as follows: in actual use, the treatment agent is first introduced into the inner cavity of the treatment box 2, and the treatment agent is made to submerge the guide plate 23 at the highest point. Then, during the quenching process, the exhaust fan 15 is used to exhaust the air, so that the generated smoke is collected by the smoke hood 12, and then introduced into the inner cavity of the treatment box 2, and the smoke is treated by the treatment agent in the treatment box 2. At the same time, the gas can be redirected by the guide plate 23 during the upward movement, thereby slowing down the gas flow speed, thereby extending the treatment time, and thus helping to improve the treatment effect of the smoke. In the process of guiding the gas through the guide plate 23, the gas moving in the water will impact the short columns 24 staggered at the bottom of the guide plate 23, thereby redirecting the gas and the treatment agent, which is beneficial to further improve the contact treatment effect of the smoke gas and the treatment agent, and then further improve the effect of removing harmful impurities. The treated gas is then adsorbed by the activated carbon filter plate 25 and the high-efficiency HEPA filter plate 26, and then discharged along the outlet pipe 21.
