Description

Technical Field

[0001] The present invention relates to the technical field of sewage discharge valve casting production, and specifically to a production device and a production method for high-performance sewage discharge valve castings. Background Technique

[0002] The production of sewage discharge valve castings refers to the process of processing metal materials (usually cast iron and cast steel, etc.) into sewage discharge valve castings through specific casting processes. Molds need to be made according to the design requirements of the sewage discharge valves. The accuracy and quality of the molds directly affect the dimensional accuracy and surface quality of the castings. Then, the molten metal material is poured into the mold and allowed to cool and solidify in the mold to form a sewage discharge valve blank with a specific shape and size. Next, the castings are subjected to subsequent treatments such as cleaning and grinding. Finally, quality inspections of the castings are carried out, including dimensional inspections, appearance inspections, and non-destructive inspections, etc., to ensure that the castings meet the quality requirements of the sewage discharge valves.

[0003] However, during the pouring process of valve castings by small production devices, the waste gas generated during the pouring process cannot be effectively adsorbed and filtered. Only simple methods such as natural ventilation are relied on to discharge the waste gas, and the generated waste gas cannot be filtered and purified, resulting in the inability to substantially treat the waste gas. As a result, the waste gas generated during the pouring process is directly discharged into the atmosphere, which not only easily affects the environment but also threatens human health, and the use effect has certain limitations.

[0016] A production method of a high-performance sewage discharge valve casting production device specifically includes the following steps:

[0017] S1: First, connect the explosion-proof centrifugal fan and the servo motor to the power supply. When in use, first place the valve mold on the placement rack, and then move the position of the movable ladle through the auxiliary device, and directly pour the molten metal into the valve mold. During the pouring process, waste gas will be generated, and the waste gas needs to be treated.

[0018] S2: Generate suction through the explosion-proof centrifugal fan. The suction is transmitted to the suction hood through the suction pipe. The suction hood sucks the waste gas generated during the pouring process. The sucked waste gas enters the filter housing through the exhaust pipe. The waste gas directly passes through the polyester fiber filter screen, the composite filter screen, and the activated carbon filter screen and is discharged through the exhaust pipe.

[0020] S4: There are three groups of polyester fiber filter screens, composite filter screens, and activated carbon filter screens inside the installation shell. When one of them needs to be replaced, directly move it out and replace it with a new group of filter screens, effectively continuously filtering the waste gas. When the polyester fiber filter screen, the composite filter screen, and the activated carbon filter screen move to the outside of the filter housing, the fixing bolts can be removed to take out the positioning plate, and the polyester fiber filter screen, the composite filter screen, and the activated carbon filter screen can be taken out respectively, facilitating their disassembly and cleaning. After cleaning, reinstall them. Drive the installation shell to move cyclically and horizontally through the rack to cyclically replace the polyester fiber filter screen, the composite filter screen, and the activated carbon filter screen, achieving the purpose of continuously filtering and purifying the waste gas, and effectively cooperating with the collection and filtration mechanism to filter and purify the waste gas generated during the pouring process.

[0021] 1. The present invention is provided with a collection and filtration mechanism, which can effectively filter and collect the waste gas generated during pouring, effectively purify the waste gas, and prevent the waste gas generated during the pouring process from being directly discharged into the atmosphere. This not only easily affects the environment but also threatens human health. The waste gas is absorbed by the suction hood and filtered through three filter meshes, which can effectively reduce the direct discharge of waste gas into the atmosphere and increase the integrity of the production of sewage valve castings.

[0022] 2. The present invention is provided with a circulation mechanism, which can effectively replace the filter mesh, improve the purification and filtration effect of the filter mesh on the waste gas, and prevent the situation that the filter mesh becomes saturated after long-term use, resulting in a reduction in the filtration effect. The servo motor, in cooperation with the transmission gear and the toothed plate, can effectively drive the installation shell to move. By moving the installation shell, it is convenient to replace the filter mesh, and thus it is convenient to recycle the filter mesh. BRIEF DESCRIPTION OF THE DRAWINGS

10. The method for producing a high-performance sewage valve casting production device according to claim 5, characterized in that: The specific steps include: S1: First, connect the explosion-proof centrifugal fan (203) and the servo motor (314) to a power source. When they are needed, first place the valve mold on the placement rack (8), then move the pouring ladle (5) by means of the auxiliary handle (4), and directly pour the molten metal into the valve mold. Waste gas will be generated during the pouring process, and the waste gas needs to be treated. S2: Suction is generated by an explosion-proof centrifugal fan (203), and the suction is transmitted to the suction hood (202) through the suction pipe (206). The exhaust gas generated during the casting process is sucked through the suction hood (202). The sucked exhaust gas enters the interior of the filter shell (208) through the exhaust pipe (204). The exhaust gas directly passes through the polyester fiber filter (201), the composite filter (211) and the activated carbon filter (210) and is discharged through the exhaust pipe (205). The polyester fiber filter (201) can filter particulate matter in the air, such as dust, metal powder, etc. The composite filter (211) comprehensively utilizes the advantages of different filter materials to achieve multi-stage filtration of the exhaust gas, and can remove a variety of pollutants in the exhaust gas. The activated carbon filter (210) can have a good removal effect on organic waste gas and odor, and effectively filter the exhaust gas generated during the casting process; S3: The transmission gear (304) can directly drive the tooth plate (303) to move, and the tooth plate (303) directly drives the mounting shell (207) to slide inside the filter shell (208) through the transmission frame (302), and drives the polyester fiber filter (201), the composite filter (211) and the activated carbon filter (210) to move respectively through the mounting shell (207), so as to facilitate their replacement; S4: Three groups of polyester fiber filter (201), composite filter (211) and activated carbon filter (210) are arranged inside the mounting shell 207. When one group needs to be replaced, it is directly removed and replaced with a new group of filter, so as to effectively and continuously filter the exhaust gas. When the polyester fiber filter (201), the composite filter (211) and the activated carbon filter (210) are replaced, the exhaust gas is effectively and continuously filtered. When the combined filter screen (211) and the activated carbon filter screen (210) are moved to the outside of the filter shell (208), the fixing bolts (312) are removed to take out the positioning plate (311), and the polyester fiber filter screen (201), the composite filter screen (211), and the activated carbon filter screen (210) are taken out respectively, so that they can be easily disassembled and cleaned. After cleaning, they can be installed again. The tooth plate (303) drives the installation shell (207) to move cyclically and horizontally to cyclically replace the polyester fiber filter screen (201), the composite filter screen (211), and the activated carbon filter screen (210), thereby achieving the purpose of continuously filtering and purifying the exhaust gas, and effectively cooperating with the collection and filtering mechanism (2) to filter and purify the exhaust gas generated during the casting process.
