Description

Technical Field

[0001] This utility model relates to the field of smoke collection technology, and in particular to a smoke collection and treatment system for a die-casting machine. Background Technology

[0002] As is well known, the problem of oil fumes generated during the operation of die-casting machines is becoming increasingly prominent. The operation process produces a large amount of oil fumes containing metal particles, grease, and other harmful substances. Direct emission without effective treatment will lead to turbid air and reduced visibility in the workshop. Long-term exposure to such an environment poses a potential threat to the health of employees and does not comply with the current national environmental protection requirements for industrial emissions. The traditional treatment method is to install a fume hood above the opening and closing mold of the die-casting machine and guide the fume collected by the fume hood to a fume purification device through a hose. However, if the fume hood is too close to the equipment, it will affect production; if it is too far away, it will affect the fume collection efficiency. The existing overall mobile design is not only inconvenient due to the weight of large equipment, but also has poor aesthetics and fume collection and treatment effect. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art and solve the existing technical problems, this utility model discloses a smoke collection and treatment system for a die-casting machine, which can improve operability, aesthetics and smoke collection and treatment effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A fume collection and treatment system for a die-casting machine includes a fume hood mounted above the equipment and a fume purifier connected to the fume hood. The fume hood is characterized by: a platform mounted on one end of the fume hood; the fume hood is divided into a movable hood and a fixed hood; the movable hood is slidably connected to the platform and can slide away from or move closer to the fixed hood; a fume guide pipe is installed on the platform; the inlet of the fume guide pipe is located inside the movable hood; and the outlet of the fume guide pipe is correspondingly connected to the inlet pipe of the fume purifier.

[0005] Furthermore, the lower part of the wall of the movable cover, away from the fixed cover, protrudes outward to form an ear chamber. Slide rails are fixed on both sides of the platform surface, and sliders that slide and engage the corresponding slide rails are fixed on the lower end faces of both side walls of the ear chamber.

[0006] Furthermore, the movable hood and the fixed hood are formed by dividing the smoke hood through a vertical dividing surface, and the dividing surface of the movable hood or the fixed hood wall is provided with a sealing strip.

[0007] Furthermore, the smoke guide tube is configured as a horn tube with two smoke inlets, the two smoke inlets of the smoke guide tube are obliquely upward corresponding to the two side walls of the movable cover, and the smoke outlet of the smoke guide tube slides through the cover wall of the movable cover away from the fixed cover.

[0008] Furthermore, the smoke purifier is fixedly installed on the platform surface. The smoke purifier includes a housing. The front end of the housing is provided with a smoke inlet pipe that connects to the smoke guide pipe. The rear upper surface of the housing is provided with a smoke outlet pipe. Inside the housing, near the smoke inlet pipe and the smoke outlet pipe, a filter device and a centrifugal fan are respectively provided.

[0013] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0014] Combined with appendix Figure 1 The aforementioned die-casting machine fume collection and treatment system includes a fume hood 1 mounted above the equipment and a fume purifier 2 connected to the fume hood 1. A platform 4 is mounted on one end of the fume hood 1. The fume hood 1 is divided into a movable hood 102 and a fixed hood 101. Specifically, the movable hood 102 and the fixed hood 101 are formed by dividing the fume hood 1 through a vertical dividing surface in the middle. A sealing strip is provided on the dividing surface of the wall of either the movable hood 102 or the fixed hood 101 to ensure that no smoke leaks when the movable hood 102 and the fixed hood 101 are combined. The movable hood 102 is slidably connected to the platform 4 and can slide away from or towards the fixed hood 101. If necessary, the lower part of the wall of the movable hood 102 away from the fixed hood 101 protrudes outward to form an ear chamber 1. 03. Both sides of the platform 4 are fixed with slide rails, and the lower ends of both side walls of the ear chamber 103 are fixed with sliders that slide and engage with the corresponding slide rails. Through the cooperation of the slide rails and sliders, the opening and closing of the movable cover 102 and the fixed cover 101 can be realized, which is very convenient. The ear chamber 103 can play a supporting and smoke guiding role when the movable cover 102 slides out of the platform 4 and approaches the fixed cover 101. In addition, the fixed cover 101 is mounted on the model of the die casting machine through the first leg 5 connected to the lower ends of both side walls. The front end of the platform 4 is left with a gap from the fixed cover 101 to facilitate the movable cover 102 to slide out of the platform 4 and cover the equipment to collect smoke. The lower platform 4 is connected to the four corners with the second leg 6 to ensure stable support. Platform 4 is equipped with a smoke guide pipe 3. The smoke inlet 301 of the smoke guide pipe 3 is located inside the movable hood 102, and the smoke outlet 302 of the smoke guide pipe 3 is connected to the smoke inlet pipe of the smoke purifier 2. The smoke collected by the fume hood 1 is directly fed into the smoke purifier 2 through the smoke guide pipe 3 for treatment, shortening the smoke treatment process and improving integration and aesthetics. As needed, as shown in the appendix Figure 2 and 3 As shown, the smoke guide pipe 3 is designed as a horn-shaped tube with two smoke inlets 301. The two smoke inlets 301 of the smoke guide pipe 3 are angled upwards, corresponding to the two side walls of the movable hood 102. This allows the rising smoke to more easily enter the smoke inlets 301 for collection after hitting the wall of the hood 1. The smoke outlet 302 of the smoke guide pipe 3 slides through the wall of the movable hood 102 away from the wall of the fixed hood 101, ensuring that the smoke guide pipe 3 and the smoke purifier 2 are fixedly installed and integrated without affecting the sliding of the movable hood 102. Specifically, perforations are made in the corresponding wall of the movable hood 102, and the perforation wall is equipped with a sealing strip to ensure that the smoke guide pipe 3 slides through the seal. In addition, as shown in the attached... Figure 4As shown, the smoke purifier 2 is fixedly installed on the platform 4. The smoke purifier 2 includes a housing 201. The front end of the housing 201 has a smoke inlet pipe connected to the smoke guide pipe 3 and a smoke outlet pipe 302. The rear upper surface of the housing 201 has a smoke outlet pipe. Inside the housing 201, near the smoke inlet pipe and the smoke outlet pipe, there are filter devices 202 and centrifugal fans 203 respectively. The filter device 202 includes three-stage filtration: an oil-water isolation screen, an adsorption electric field, and reverse osmosis return cotton. Under the action of the centrifugal fan 203, the smoke enters from the smoke inlet pipe, is filtered by the filter device 202, and then exits from the smoke outlet pipe. The exhaust system employs a three-stage filtration and purification mechanism to achieve optimal purification results. The first-stage filtration uses a pre-filtered oil-water metal barrier to intercept large oil droplets, water droplets, and metal impurities. The second-stage purification combines molecular ionization and adsorption technologies to further separate and adsorb fine particles and harmful substances. The third-stage filtration uses a post-reverse osmosis recirculation cotton to further filter the air that has passed through the first two stages of filtration and purification, and to prevent the backflow of external foreign matter. After this three-stage filtration, the overall filtration efficiency of the equipment reaches over 95%, effectively ensuring the quality of the exhaust air.

[0015] When the die-casting machine needs to release smoke during production, the movable hood 102 is pushed to slide on the platform 4 and approach the fixed hood 101 until it closes with the fixed hood 101 and covers the equipment together. After the smoke rises into the hood 1, it first contacts the wall of the hood 1 for cooling, and then enters the smoke purifier 2 directly through the smoke guide pipe 3 for purification. Since the die-casting machine generates smoke through opening and closing molds, the smoke generated is short-term and intermittent. Therefore, after collecting smoke once, the movable hood 102 can be slid back to facilitate mold adjustment and continued production.

[0016] The smoke collection and treatment system for die-casting machines described in this utility model allows for the following operation: When the die-casting machine requires the release of smoke during production, the movable hood is pushed, causing it to slide on the platform closer to the fixed hood until it closes with the fixed hood, covering the equipment together. After the smoke rises into the hood, it first contacts the hood wall for cooling, and then directly enters the smoke purifier through the smoke guide pipe for purification. Since the die-casting machine generates smoke through opening and closing molds, the smoke produced is short-lived and intermittent. Therefore, after collecting smoke once, the movable hood can be slid back to allow for mold adjustment and continued production.
