Description

Technical Field

[0001] This utility model relates to the technical field of high-temperature treatment devices for aluminum castings, and in particular to a high-temperature treatment device for aluminum castings of actuator cavities that can treat waste gas. Background Technology

[0002] In fields such as automotive manufacturing and industrial automation, actuator cavities, as key components, are commonly cast from aluminum alloys to meet the requirements of lightweighting and complex structures. These castings must undergo rigorous heat treatment processes, including solution treatment and aging, to achieve the necessary mechanical strength, dimensional stability, and fatigue resistance. However, traditional heat treatment furnaces face significant challenges during high-temperature processing. Organic pollutants such as residual mold release agents, cutting oils, and lubricating greases on the surface of aluminum castings decompose at high temperatures, generating large amounts of complex waste gas containing fumes, volatile organic compounds (VOCs), particulate matter, and irritating odors. Direct emission without effective treatment poses significant risks. Not only does it severely pollute the environment and violate increasingly stringent environmental regulations, but it also endangers the health of operators and may cause safety hazards due to the accumulation of exhaust gas. Although some companies have tried to add post-exhaust gas treatment equipment outside the furnace, there are often problems such as low exhaust gas collection efficiency, large system footprint, high energy consumption, and poor coordination between different treatment units (such as spraying and adsorption), resulting in unstable treatment effects and high maintenance costs. There is an urgent need to develop a highly integrated special device optimized for the characteristics of exhaust gas from the heat treatment of aluminum castings, which can achieve efficient capture and multi-stage purification of exhaust gas at the source while ensuring the precision of the heat treatment process, thus meeting the dual requirements of clean production and sustainable development. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-temperature treatment device for aluminum castings of actuator cavities capable of treating waste gas, comprising:

[0006] The base has a high-temperature furnace installed on its upper surface and an air inlet pipe installed on one side of the high-temperature furnace. A sealing groove is opened on the upper surface of the high-temperature furnace. Hydraulic telescopic rods are installed around the upper surface of the base, and a cover plate is fixed at the telescopic end of the hydraulic telescopic rod.

Multiple air suction pipes are embedded in the lower end face of the cover plate, and an air collection pipe is fixed to the upper end face of the cover plate.

[0008] The exhaust gas pretreatment assembly is installed on the upper surface of the cover plate. The exhaust gas pretreatment assembly includes an exhaust gas collection box fixed to the upper surface of the cover plate.

Sliding grooves are fixed on both sides of the inner wall of the exhaust gas collection box. Sliding strips are slidably sleeved in the inner cavity of the sliding grooves. A multi-mesh screen is fixed between two sliding strips. A handle is fixed on the front end of the multi-mesh screen.

[0009] A filter assembly installed above the gas collection box includes a filter chamber fixed to the upper surface of the gas collection box, an exhaust port fixed to the upper surface of the filter chamber, an activated carbon filter screen inserted into the inner cavity of the filter chamber, and a sealing plate fixed to the front end of the activated carbon filter screen.

[0010] The negative pressure air pump installed on the upper surface of the gas collection box is used to send the gas in the gas collection box to the filter assembly.

[0011] As a further description of the above technical solution:

[0012] The cover plate is located above the high-temperature furnace, and the cover plate and the base form a liftable structure through a hydraulic telescopic rod.

[0013] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:

[0022] The sealing plate is assembled and connected to the front end of the filter chamber by bolts. The input end of the negative pressure air pump passes through the upper end of the air collection box and is located above the spray pipe.

This structure not only significantly improves the waste gas collection efficiency and purification effect, ensuring compliance with emission standards, but also greatly reduces the equipment footprint. At the same time, the spray system, multi-mesh screen, and activated carbon filter all adopt a quick-release structure, which greatly simplifies the maintenance process and effectively reduces operating costs. In summary, this invention solves the problems in the background technology. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] Reference Figures 1-4 A high-temperature treatment device for aluminum castings of actuator cavities capable of treating waste gas, comprising:

[0033] The base 1 has a high-temperature furnace 2 installed on its upper surface, and an air inlet pipe 3 is installed on one side of the high-temperature furnace 2. A sealing groove 4 is opened on the upper surface of the high-temperature furnace 2. Hydraulic telescopic rods 5 are installed around the upper surface of the base 1, and a cover plate 6 is fixed on the telescopic end of the hydraulic telescopic rod 5.

[0034] The high-temperature furnace 2 is equipped with heating elements and temperature sensors to perform precise and controllable high-temperature heat treatment on the aluminum casting of the actuator cavity placed inside it. The air inlet pipe 3 is used to introduce protective atmosphere or combustion air into the high-temperature furnace 2.

[0035] Positioning pins 7 are fixed around the lower end face of the cover plate 6. A sealing steel ring 8 is fixed on the lower end face of the cover plate 6. Multiple suction pipes 9 are embedded on the lower end face of the cover plate 6, and an air collection pipe 10 is fixed on the upper end face of the cover plate 6.

[0036] The input end of the suction pipe 9 extends to the bottom of the cover plate 6. When the cover plate 6 is closed on the high-temperature furnace 2, the inlet of the suction pipe 9 is located in the upper space of the high-temperature furnace 2 chamber, which is used to directly suck up the waste gas (including oil fumes, volatile organic compounds VOCs, particulate matter, etc.) generated during the high-temperature treatment process. The gas collection pipe 10 is used to collect the waste gas extracted from multiple suction pipes 9.

[0037] The exhaust gas pretreatment assembly 11 is installed on the upper surface of the cover plate 6. The exhaust gas pretreatment assembly 11 includes a gas collection box 1101 fixed to the upper surface of the cover plate 6. The front end of the gas collection box 1101 is equipped with an opening and closing door 1102 through a hinge. Multiple spray pipes 1103 are installed horizontally on the inner wall of the gas collection box 1101. A liquid pump 1105 is installed at the lower end of the inner cavity of the gas collection box 1101. A water guide pipe 1104 is installed on one side of the gas collection box 1101. Sliding grooves 1106 are fixed on both sides of the inner wall of the gas collection box 1101. Sliding strips 1107 are slidably sleeved in the inner cavity of the sliding grooves 1106. A multi-mesh mesh 1108 is fixed between the two sliding strips 1107. A handle 1109 is fixed on the front end of the multi-mesh mesh 1108.

[0038] A spray head is installed below the spray pipe 1103. The liquid pump 1105 pumps the spray liquid (usually water or absorbent containing chemical agents) stored at the bottom of the gas collection box 1101 to the spray pipe 1103 through the water guide pipe 1104, and sprays it downwards through the spray head. The spray liquid is used to initially cool the waste gas, dissolve some soluble gases (such as acidic gases), and remove larger particles and oil droplets. The multi-mesh screen 1108 is located below the spray area. Its mesh structure can effectively intercept larger particles, condensed oil droplets, and water mist that are not carried away by the spray liquid, increasing the gas-liquid contact area and improving the purification efficiency. The multi-mesh screen 1108 can be pulled out along the slide 1106 through the handle 1109 for easy cleaning or replacement. A drain valve is provided at the rear end of the bottom of the gas collection box 1101 for discharging waste liquid.

[0039] The filter assembly 13 is installed above the gas collection box 1101. The filter assembly 13 includes a filter chamber 1301 fixed to the upper end face of the gas collection box 1101. An exhaust port 1302 is fixed to the upper end face of the filter chamber 1301. An activated carbon filter screen 1303 is inserted into the inner cavity of the filter chamber 1301. A sealing plate 1304 is fixed to the front end face of the activated carbon filter screen 1303.

[0040] The exhaust gas, pressurized and transported by the negative pressure air pump 12, enters the filter chamber 1301 and passes through the activated carbon filter screen 1303. The activated carbon filter screen 1303 utilizes its specific surface area and adsorption capacity to further adsorb and remove residual organic pollutants (VOCs), odors, and smaller particulate matter in the exhaust gas. Finally, the purified gas is discharged through the exhaust port 1302 in compliance with standards. The sealing plate 1304 is sealed and fixed with bolts to ensure the airtightness of the filter chamber 1301 and facilitate the periodic replacement of the activated carbon filter screen 1303.

[0041] The negative pressure air pump 12, installed on the upper end face of the gas collection box 1101, is used to send the gas in the gas collection box 1101 into the filter assembly 13.

[0042] The negative pressure air pump 12 generates negative pressure above the spray area in the air collection box 1101, which forces the exhaust gas after spray pretreatment to be drawn up.

[0043] Furthermore, the cover plate 6 is located above the high-temperature furnace 2, and the cover plate 6 forms a liftable structure with the base 1 through the hydraulic telescopic rod 5.

[0044] Furthermore, the positioning pin 7 is inserted into the upper end face of the high-temperature furnace 2 for positioning connection between the cover plate 6 and the high-temperature furnace 2.

[0045] Furthermore, the output ends of multiple intake pipes 9 are connected to the air collection pipe 10.

[0046] Furthermore, the input end of the water guide pipe 1104 is fixedly connected to the liquid pump 1105, and the output end of the water guide pipe 1104 is fixedly connected to the spray pipe 1103.

[0047] Furthermore, the spray pipe 1103 is arranged parallel above the multi-mesh net 1108.

[0048] Furthermore, the sealing plate 1304 is assembled and connected to the front end face of the filter chamber 1301 by bolts, the input end of the negative pressure air pump 12 passes through the upper end face of the air collection box 1101 and is located above the spray pipe 1103, and the output end of the negative pressure air pump 12 passes through one side of the filter chamber 1301 and is located below the activated carbon filter screen 1303.

[0049] Working principle: In use, the aluminum casting to be processed is first placed into the high-temperature furnace 2. The cover plate 6 is closed under the drive of the hydraulic telescopic rod 5, and precise positioning and sealing are achieved by the positioning pin 7 and the sealing steel ring 8. The high-temperature furnace 2 heat-treats the casting. The negative pressure air pump 12 operates, and the generated exhaust gas is drawn in real time by the suction pipe 9 and enters the gas collection box 1101 of the exhaust gas pretreatment component 11 through the gas collection pipe 10. The exhaust gas is first cooled, washed and removed by the liquid sprayed by the spray pipe 1103, and some pollutants and particulate matter are removed. Then it is further intercepted by the multi-mesh screen 1108. The negative pressure air pump 12 draws the pretreated gas to the filter component 13, where it is deeply adsorbed and purified by the activated carbon filter screen 1303. Finally, the clean gas is discharged from the exhaust port 1302. The opening and closing door 1102 facilitates the maintenance of the spray system and the multi-mesh screen 1108, and the sealing plate 1304 facilitates the replacement of the activated carbon filter screen 1303. This completes the working principle of this utility model.
