Description

Technical Field

[0001] The utility model relates to the technical field of tail gas collection and treatment, in particular to a device for automatically collecting and treating particles in casting tail gas. Background Art

[0002] The foundry industry is an important basic industry in many industrial fields, and its production process produces a lot of dust and harmful gases. Among them, particulate matter is one of the main factors causing environmental pollution and harming health. In order to improve these environmental problems, researchers have been looking for more effective ways to collect and treat particulate matter in casting exhaust gas. There are some problems with current methods of collecting and treating particulate matter. For example, these methods may not be able to effectively capture all particulate matter, or require additional energy consumption. Therefore, researchers are looking for new solutions.

[0003] For example, a tail gas treatment device for chemical environmental protection with patent publication number CN211913169U has a tail gas particle sedimentation water tank fixedly installed at the lower part of the interior of the box body, which is convenient for conveying the tail gas to the tail gas particle sedimentation water tank. Under the action of water, the particulate matter in the tail gas can be cleaned, so that the particulate matter is not easily discharged into the air. An exhaust gas collecting hood is placed above the tail gas particle sedimentation water tank, which is convenient for collecting the exhaust gas in the exhaust gas collecting hood and facilitating better discharge through the air pipe. A water outlet is opened on the right side below the box body and the tail gas particle sedimentation water tank, which is convenient for discharging water and particulate matter. A leak-proof plug is inserted inside the water outlet, which is convenient for sealing the box body and the tail gas particle sedimentation water tank, so that water and tail gas are not easy to leak.

[0004] A large amount of dusty exhaust gas will be generated during the cooling and polishing process of castings, which needs to be treated in time to ensure the quality of castings and the health of employees. However, the current exhaust gas collection and treatment device in the foundry workshop usually installs the conventional smoke exhaust gas treatment device directly in the foundry workshop. The efficiency of collecting and treating the smoke exhaust gas in the foundry workshop is low, and it cannot treat the particulate matter in the exhaust gas. For this reason, we propose a new automatic collection and treatment device for particulate matter in casting exhaust gas. Utility Model Content

[0029] The main body mechanism 1 is used to support the filtering mechanism 3 and the exhaust mechanism 2. The exhaust mechanism 2 is used to discharge the exhaust gas, and the filtering mechanism 3 is used to adsorb particulate matter in the exhaust gas.

[0030] The filtering mechanism 3 comprises:

[0031] The filter box 301 is installed on one side of the top of the main body 1, and notches 307 are set at both ends of the filter box 301. A box bar frame 306 is installed on the top of the filter box 301, and a box door 305 is installed inside the box bar frame 306. A first handle 302 is installed on the top of the box door 305.

[0032] The main body 1 includes:

[0033] A bottom plate 102 is installed at the bottom end of the filter box 301 , and support columns 103 are installed around the bottom end of the bottom plate 102 , and universal wheels 101 are installed at the bottom ends of the support columns 103 .

[0034] The exhaust mechanism 2 comprises:

[0035] An air inlet pipe 201 is installed on one side of the filter box 301, and a connecting pipe 202 is installed on the other side of the filter box 301.
