Description

Technical Field

[0001] This utility model relates to the field of smoking devices, specifically a smoking device for a casting machine. Background Technology

[0002] During the casting process, the melting of metal and pouring of castings by casting machines generate a large amount of fumes containing metal particles and harmful gases. Traditional casting workshops mostly rely on natural ventilation or simple exhaust systems to handle these fumes. This approach has significant drawbacks: firstly, natural ventilation is inefficient, making it difficult to quickly remove fumes from the workshop, resulting in excessively high fumes concentrations. Long-term inhalation of these fumes can cause respiratory illnesses and other health problems for operators. Secondly, simple exhaust systems lack effective filtration and purification functions, directly releasing untreated fumes into the external environment, causing air pollution and failing to meet environmental protection requirements.

[0003] Furthermore, some existing fumigation devices have limited fumigation range, failing to fully cover the areas where casting machines generate smoke and dust. Additionally, the fumigation components are typically fixed in place, making it difficult to adapt to the working trajectory of the moving parts of the casting machine, resulting in incomplete smoke and dust collection. Simultaneously, the filter components have poor filtration efficiency, are prone to clogging, and require frequent replacement, increasing operating costs and maintenance workload. To address these issues, this utility model provides a fumigation device for casting machines to improve smoke and dust collection efficiency and purification effect, meeting both environmental protection and production requirements. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the fume extraction devices of existing casting machines, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a fume extraction device for a foundry machine, which aims to overcome the shortcomings of existing foundry machine fume treatment equipment, such as incomplete collection, poor purification effect, and weak adaptability. The proposed fume extraction device for a foundry machine achieves comprehensive collection and efficient purification of foundry machine fumes, while also possessing good adaptability. It can work in conjunction with the moving parts of the foundry machine, reducing maintenance costs and improving the workshop environment and surrounding air quality.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A fumigation device for a casting machine, comprising a casting machine body and a fumigation assembly;

[0009] The casting machine body is equipped with a fumigation assembly, which includes a fumigation hood. A telescopic pipe is installed on the top of the fumigation hood, and a sleeve is provided on the top of the telescopic pipe. The sleeve is connected to a filter assembly through a connecting pipe. The filter assembly includes a housing, which has a filter chamber and an air outlet chamber. A filter screen and an activated carbon adsorption layer are installed in the filter chamber. The filter chamber is connected to the air outlet chamber through a connecting hole, and a negative pressure fan is installed at the opening of the air outlet chamber.

[0010] As a preferred embodiment of the fumigation device for a casting machine according to the present invention, the fumigation hood is provided in multiple ways, evenly distributed around the main body of the casting machine, and the top inner cavity of the fumigation hood is evenly provided with air intake ports.

[0011] In a preferred embodiment of the fumigation device for a casting machine according to the present invention, the telescopic tube and the sleeve are connected to the movable part of the main body of the casting machine through a connecting frame, and one end of the telescopic tube is located in the inner cavity of the sleeve and is slidably connected to the sleeve.

[0012] As a preferred embodiment of the fumigation device for a casting machine according to the present invention, the filter chamber is provided in multiple ways and is evenly distributed in the inner cavity of the box in four directions.

[0013] In a preferred embodiment of the fumigation device for a casting machine according to the present invention, the sleeve is connected to the filter chamber via a connecting pipe, the filter screen is located outside the activated carbon adsorption layer, and the activated carbon adsorption layer is located on the side close to the connecting hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Multiple fume hoods are evenly distributed around the main body of the casting machine, and together with the uniform air intake on the top of the fume hood, they can cover the area where smoke and dust are generated in all directions, preventing the spread of smoke and dust; at the same time, the telescopic tube and the sleeve are slidably connected, and linked with the moving part of the main body of the casting machine through the connecting frame, so that the position and length can be flexibly adjusted with the moving part of the casting machine to ensure that there are no dead corners in the collection of smoke and dust, and solve the problem that traditional devices cannot adapt to the movement of the casting machine.

[0015] 2. The filter chamber adopts a multi-stage filtration structure of "filter screen + activated carbon adsorption layer". The filter screen first intercepts large particulate impurities and protects the activated carbon adsorption layer from being blocked. The activated carbon adsorption layer then adsorbs fine particles and harmful gases.

[0025] This utility model provides the following technical solution: a fumigation device for a foundry machine, in which multiple fumigation hoods are evenly distributed around the main body of the foundry machine during use, and with the uniform air intake on the top of the fumigation hood, the area where smoke and dust are generated can be covered in all directions to prevent the spread of smoke and dust; at the same time, the telescopic tube and the sleeve are slidably connected, and are linked with the moving part of the main body of the foundry machine through the connecting frame, so that the position and length can be flexibly adjusted to follow the moving part of the foundry machine to ensure that there are no dead corners in the collection of smoke and dust, and solve the problem that traditional devices cannot adapt to the movement of the foundry machine.

[0026] The filter chamber adopts a multi-stage filtration structure of "filter screen + activated carbon adsorption layer". The filter screen first intercepts large particulate impurities and protects the activated carbon adsorption layer from being blocked. The activated carbon adsorption layer then adsorbs fine particles and harmful gases. The dual purification ensures the cleanliness of the discharged gas, effectively reducing pollution to the workshop and surrounding environment and meeting national environmental protection emission standards.

[0027] Figures 1-3 The diagram shown is a structural schematic of the first embodiment of a fumigation device for a casting machine according to this utility model. Please refer to [link / reference]. Figures 1-3 The smoking device for a casting machine according to this embodiment includes a casting machine body 100 and a smoking component 200.

[0028] A fumigation assembly 200 is installed on the main body 100 of the casting machine. The fumigation assembly 200 includes a fumigation hood 210. A telescopic pipe 220 is installed on the top of the fumigation hood 210. A sleeve 230 is provided on the top of the telescopic pipe 220. The sleeve 230 is connected to the filter assembly 240 through a connecting pipe 231. The filter assembly 240 includes a housing 241. A filter chamber 242 and an exhaust chamber 245 are opened in the housing 241. A filter screen 243 and an activated carbon adsorption layer 244 are installed in the filter chamber 242. The filter chamber 242 is connected to the exhaust chamber 245 through a connecting hole 246. A negative pressure fan 250 is installed at the opening of the exhaust chamber 245.

[0029] Installation of the fume extraction assembly 200: First, based on the dimensions of the casting machine body 100 and the area where smoke and dust are generated, determine the number and location of the fume extraction hoods 210. Evenly fix multiple fume extraction hoods 210 at suitable positions around the casting machine body 100, ensuring that the air intake 211 at the top of the fume extraction hood 210 covers the point where smoke and dust are generated. Next, weld or thread a telescopic tube 220 to the top of each fume extraction hood 210, and fit a sleeve 230 onto the top of the telescopic tube 220 (ensuring the telescopic tube 220 can slide flexibly within the sleeve 230). Then, use a connecting bracket 260 to fix the telescopic tube 220 and the sleeve 230 to the moving parts of the casting machine body 100 (such as the pouring arm, melting furnace moving frame, etc.), ensuring that the movement of the moving parts can drive the fume extraction assembly 200 to move synchronously.

[0030] Filter assembly 240 installation: Select a well-ventilated and easily maintainable location within the foundry to place the housing 241 of the filter assembly 240. Inside the housing 241, create multiple filter chambers 242 (usually four, corresponding to the four directions of the housing 241) and one exhaust chamber 245 according to the design dimensions, ensuring that the filter chambers 242 and the exhaust chamber 245 are connected through the connecting hole 246. Subsequently, install a filter screen 243 and an activated carbon adsorption layer 244 in each filter chamber 242. The filter screen 243 is fixed on the side of the filter chamber 242 closest to the interface of the connecting pipe 231 (outer side), and the activated carbon adsorption layer 244 is fixed on the side closest to the connecting hole 246 (inner side). During installation, ensure that the filter screen 243 and the activated carbon adsorption layer 244 are tightly fitted to the inner wall of the filter chamber 242 to prevent dust from bypassing the filter structure through gaps. Finally, the negative pressure fan 250 is bolted to the opening of the air outlet chamber 245 to ensure a sealed connection between the negative pressure fan 250 and the air outlet chamber 245 and prevent air leakage.

[0031] Piping Connection: Use connecting pipe 231 to connect the outlet of each sleeve 230 to the corresponding filter chamber 242 interface on the filter assembly 240 housing 241. Use flange or threaded connections, and wrap sealing tape or install sealing rings at the interfaces to ensure a tight seal and prevent dust leakage. After connection, check that all connections are secure and sealed, ensuring there are no loose parts or leaks.

[0032] Pre-start inspection: Before use, check whether the fume hood 210 is intact and in the correct position, whether the sliding of the telescopic tube 220 and the sleeve 230 is flexible, and whether the sealing of the connecting tube 231 and each interface is good; check whether the filter screen 243 and the activated carbon adsorption layer 244 in the filter chamber 242 are installed in place and are undamaged, and whether the power cord of the negative pressure fan 250 is connected normally and undamaged.

[0033] Start-up device: First, start the negative pressure fan 250 of the filter component 240 and observe whether the negative pressure fan 250 is operating normally and whether there is any abnormal noise; after the negative pressure fan 250 is running stably, confirm that there is obvious suction at the air intake 211 of the fume hood 210, then the casting machine can be started for production operations.

[0034] Monitoring during operation: During the operation of the casting machine, observe whether the smoke extraction component 200 moves normally with the moving parts of the casting machine and whether the telescopic tube 220 can be flexibly adjusted in length to ensure that the air intake 211 is always aligned with the area where smoke and dust are generated; at the same time, pay attention to the working status of the negative pressure fan 250 and the exhaust gas situation. If obvious smoke and dust are found in the exhaust gas, or if the negative pressure fan 250 has abnormal noise or a decrease in speed, the machine should be stopped and inspected in time.

[0035] Shutdown procedure: After the casting machine has finished operating, first turn off the casting machine. After the fume hood 210 continues to collect residual smoke and dust for 5-10 minutes, turn off the negative pressure fan 250 to ensure that the residual smoke and dust in the workshop is fully collected and purified.

[0036] Combination Figures 1-3 The working principle of the fume extraction device for a casting machine in this embodiment is as follows:

[0037] Negative pressure generation stage: The negative pressure fan 250 at the opening of the air outlet chamber 245 is activated, and the operation of the negative pressure fan 250 creates a negative pressure environment inside the air outlet chamber 245. Since the filter chamber 242 is connected to the air outlet chamber 245 through the connecting hole 246, negative pressure is also generated inside the filter chamber 242, which is then transmitted to the smoke hood 210 through the connecting pipe 231, the sleeve 230, and the telescopic pipe 220, so that the air inlet 211 at the top of the smoke hood 210 forms suction.

[0038] Smoke and dust collection stage: The smoke and dust generated by the casting machine body 100 spreads to all sides. Multiple smoke hoods 210, evenly distributed around the casting machine body 100, draw in the smoke and dust through the air intake 211 at the top. During this process, if the moving parts of the casting machine body 100 move, the telescopic tube 220 connected to the moving parts via the connecting frame 260 will slide within the sleeve 230. Adjusting the length of the telescopic tube 220 simultaneously moves the smoke hoods 210, ensuring that the air intake 211 is always aligned with the smoke and dust generation area, achieving continuous and comprehensive collection of smoke and dust.

[0039] Smoke and dust transport stage: The smoke and dust drawn into the smoke hood 210 are transported through the telescopic tube 220 and the sleeve 230 under negative pressure and then into the connecting tube 231. The smoke and dust are then transported to the filter chamber 242 of the filter assembly 240 through the connecting tube 231, thus completing the smoke and dust transport process.

[0040] Multi-stage purification process: The smoke entering the filter chamber 242 first passes through the outer filter screen 243, which intercepts larger metal particles, dust, and other impurities in the smoke. After preliminary filtration, the smoke continues to move towards the connecting hole 246 and passes through the inner activated carbon adsorption layer 244. This adsorption layer uses its porous structure to adsorb fine particles and harmful gases (such as sulfur dioxide and nitrogen oxides) in the smoke, achieving deep purification of the smoke.

[0041] Post-purification emission stage: The clean gas purified by the filter chamber 242 enters the exhaust chamber 245 through the connecting hole 246, and is finally discharged from the opening of the exhaust chamber 245 under the action of the negative pressure fan 250, completing the entire dust collection and purification process.
