High-temperature-resistant dust collector

Abstract

The invention discloses a high-temperature-resistant dust collector. The high-temperature-resistant dust collector comprises a lower dust collecting barrel, a dual-layer dust collecting barrel wall, a dust-collecting-barrel water feeding valve, a dust collecting opening, a cyclone separator, an upper-barrel separating plate, a water-flow shielding cover, a dual-layer barrel wall, an upper cover, an upper supporting threaded rod, a vacuum pump linking pipe, a center pipe, an inner flow-reduction upper plate, an outer flow-reduction upper plate, an inner flow-reduction lower plate, an outer flow-reduction lower plate, a vacuum pump and a water discharging valve; dust airflow is subjected to first filtering through the cyclone separator, and then the filtered dust airflow enters an upper layer and is subjected to second water filtering; through second water filtering, tiny dust can be filtered out, air can be cooled, and the dual effects are achieved; third filtering is carried out through a filtering net of the upper cover, the filtering accuracy is high, and the cleanliness of discharged air is guaranteed; the dual-layer dust collecting barrel wall and the dual-layer barrel wall are provided with annular spaces, water is injected during working, the temperature of the outer wall of a machine cannot be over high, cooling parts such as a cooling fan of a machine box wall are omitted, and the cost is saved.

Description

technical field [0001] The invention relates to a vacuum cleaner, in particular to a high temperature resistant vacuum cleaner. Background technique [0002] At present, there is no good collection method for the recovery of high-temperature materials in the market. Generally, industrial vacuum cleaners are used for collection, but the casing of the machine will heat up instantaneously, causing the temperature of the motor to rise and fail to work normally, eventually causing the motor to burn out. Moreover, most of the vacuum cleaners currently on the market are single-layer barrels. When collecting high-temperature materials, There will be overheating of the machine shell and the motor box. The current technology mostly uses cooling fans and other components, which are costly. In some high-temperature vacuum cleaners, all the hot air flows through the separator. There is only one filtering process, and the filtering accuracy is not high. Due to the high temperature of the...

Generally, industrial vacuum cleaners are used for collection, but the casing of the machine will heat up instantaneously, causing the temperature of the motor to rise and fail to work normally, eventually causing the motor to burn out. Moreover, most of the vacuum cleaners currently on the market are single-layer barrels. When collecting high-temperature materials, There will be overheating of the machine shell and the motor box. The current technology mostly uses components such as cooling fans, which cost a lot

In some high-temperature vacuum cleaners, all the hot air flow passes through the separator. There is only one filtering process, and the filtering accuracy is not high. Due to the high temperature of the suction pipe and suction head, it is still necessary to wear high-temperature resistant gloves during operation.

For example, existing equipment such as CN201310568314.7 high-temperature-resistant vacuum cleaner has low filtration accuracy, high-temperature heat generation on the outer wall, and frequent tripping, etc.
