Description

Technical Field

[0001] The invention relates to the technical field of sewage valve casting production, in particular to a production device and a production method of a high-performance sewage valve casting. Background Art

[0002] The production of sewage valve castings refers to the process of processing metal materials (usually cast iron and cast steel, etc.) into sewage valve castings through a specific casting process. The mold must be made according to the design requirements of the sewage valve. The accuracy and quality of the mold directly affect the dimensional accuracy and surface quality of the casting. Then, the molten metal material is injected into the mold and allowed to cool and solidify in the mold to form a sewage valve blank with a specific shape and size. Then, the casting is cleaned and polished, and finally the casting is quality inspected, including dimensional inspection, appearance inspection, and non-destructive testing, to ensure that the casting meets the quality requirements of the sewage valve.

[0003] However, in the process of pouring valve castings in small-scale production equipment, the waste gas generated in the pouring process cannot be effectively adsorbed and filtered. The waste gas can only be discharged by simple methods such as natural ventilation. The waste gas generated cannot be filtered and purified, resulting in the inability to substantially treat the waste gas. As a result, the waste gas generated in the pouring process is directly discharged into the atmosphere, which is not only easy to affect the environment, but also threatens human health, and the use effect has certain limitations.

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

[0017] S1: First, connect the explosion-proof centrifugal fan and servo motor to the power supply. When you need to use them, place the valve mold on the rack first, then move the ladle by the auxiliary handle and pour the molten metal directly into the valve mold. Waste gas will be generated during the pouring process and needs to be treated;

[0018] S2: Suction is generated by an explosion-proof centrifugal fan, which is transmitted to the suction hood through the suction pipe.

[0020] S4: Three groups of polyester fiber filters, composite filters and activated carbon filters are arranged inside the installation shell. When one group needs to be replaced, it is directly removed and replaced with a new group of filters to effectively and continuously filter the exhaust gas. When the polyester fiber filter, composite filter and activated carbon filter are moved to the outside of the filter shell, the fixing bolts can be removed to take out the positioning plate, and the polyester fiber filter, composite filter and activated carbon filter can be taken out respectively, so that they can be disassembled and cleaned conveniently. After cleaning, they can be installed again. The installation shell is driven by the tooth plate to cyclically translate and replace the polyester fiber filter, composite filter and activated carbon filter, so as to achieve the purpose of continuously filtering and purifying the exhaust gas, and effectively cooperate with the collection and filtering mechanism to filter and purify the exhaust gas generated during the pouring process.

[0021] 1. The present invention is provided with a collection and filtering mechanism, which can effectively filter and collect the waste gas generated by pouring, effectively purify the waste gas, and prevent the waste gas generated during the pouring process from being directly discharged into the atmosphere, which is not only easy to affect the environment, but also threatens human health. The exhaust hood is used to absorb the exhaust gas, and then it is filtered through three filter screens, which can effectively reduce the direct discharge of the exhaust 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, increase the purification and filtering effect of the filter on the exhaust gas, and prevent the filter from being saturated due to long-term use, thereby reducing the filtering effect. The servo motor cooperates with the transmission gear and the tooth plate to effectively drive the mounting shell to move, and the movement of the mounting shell facilitates the replacement of the filter, thereby facilitating the recycling of the filter.

10. A method for producing a high-performance sewage valve casting production device according to any one of claims 1 to 9, Features: 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 is 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 various pollutants in the exhaust gas. The activated carbon filter (210) can have a good removal effect on organic waste gas and odor, and effectively filters 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 filters (201), a composite filter (211) and an activated carbon filter (210) are arranged inside the installation shell 207. When one group needs to be replaced, it is directly removed and replaced with a new group of filters 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 moved to the outside of the filter shell (208), the fixing bolts (312) can be removed to take out the positioning plate (311), and the polyester fiber filter (201), the composite filter (211) and the activated carbon filter (210) can be removed. The polyester fiber filter (201), the composite filter (211) and the activated carbon filter (210) are convenient to disassemble and clean, and then install after cleaning. The tooth plate (303) drives the installation shell (207) to cyclically translate and replace the polyester fiber filter (201), the composite filter (211) and the activated carbon filter (210), thereby achieving the purpose of continuously filtering and purifying the waste gas, and effectively cooperating with the collection and filtering mechanism (2) to filter and purify the waste gas generated during the casting process.
