Description

Background technique

With the country's emphasis on environmental protection, industrial filters have become an indispensable part of industrial production; industrial filters are generally divided into two types: air filtration and water filtration. Industrial air filters are mainly used to filter industrial dust and ensure The cleanliness of the air in the factory building, and industrial water filters are mainly used to filter industrial circulating water; generally, traditional industrial filters can only be used to filter air or industrial water alone, and cannot achieve the dual-use function of one machine; therefore , there is a need for an industrial filter for factories that can filter both air and industrial water, thereby solving problems that traditional industrial filters cannot solve.

For example, the patent No. CN105344169B provides an industrial filter. The device includes a first filter and a second filter. The first filter uses the larger filtering area of the first filter bag to reduce air flow resistance. Function, the first filter also extends the service life by blocking large particles on the outer surface of the first filter bag, and the second filter is connected to the first filter through a connecting frame to achieve installation space of savings. This application can make the outgoing air flow smoother and increase the service life of industrial filters. However, this solution can only filter the air and cannot filter industrial circulating water; at the same time, this solution cannot realize the self-cleaning of the filter bag, and the filter bag still needs to be disassembled for cleaning after long-term use; this solution also cannot achieve the purpose of filtering the filter bag. The disinfection and cleaning function of the industrial filter will cause bacteria and fungi to breed inside the industrial filter if used for a long time. If it is continued to be used, the bacteria and fungi in the factory will exceed the standard, thus threatening the life safety of workers; this plan does not control the air circulation device Facilities have different air circulation speeds under different weather conditions. If the air circulation speed is not controlled artificially, the filtration efficiency of industrial filters may decrease, thereby failing to meet the needs of industrial production in the factory; this solution cannot yet achieve the goal of filtering air. humidification function.

Working principle of the present invention: Figure 1 shows the usage mode and corresponding scene of the present invention. The posture control of the industrial filter for factory use is composed of a self-cleaning bag filter device 2, a shaftless blowing humidification device 3 and a single The posture of the one-way ventilation device 4 is determined by the shaftless blowing and humidifying device 3. The posture of the shaftless blowing and humidifying device 3 is determined by the self-cleaning bag filter device 2. Therefore, the self-cleaning bag filter device 2 It is the core of the industrial filter usage process.

Taking Embodiment 1 as an example, the shaftless propelling fan 303 on the shaftless blowing and humidifying device 3 creates suction, sucking the industrial circulating water or air into the primary filtering device 1, and then passes through the primary filter screen 103 for preliminary filtration before entering. In the bag filter and dust cleaning assembly 202 of the self-cleaning bag filter device 2, after being filtered again by the bag filter and dust cleaning assembly 202, it enters the shaftless blowing humidification device 3, and then the one-way air blower and humidifier is filtered by water pressure or air pressure. The first opening and closing blades 403 and the second opening and closing blades 404 on the ventilation device 4 are pushed apart to realize the filtering function; when the filtered air needs to be humidified, the waterproof sealing cover 302 on the shaftless blowing and humidifying device 3 needs to be opened in advance. The water in the annular water tank 304 is sprayed out to realize the humidification function of the air; when the self-cleaning bag filter device 2 needs to be self-cleaned, manually push and pull the self-cleaning handle 205 so that the bag filter cleaning assembly 202 The filter bag pocket 20203 shakes back and forth to shake out the internal dust toward the primary filter device 1, and then the switch baffle 50103 on the dust storage device 5 is manually opened, so that the dust shaken off enters the dust storage tank 502, and at the same time The annular water tank 304 is also used to spray the disinfectant liquid, and the shaftless propulsion fan 303 blows the disinfectant liquid away to realize the disinfection and dust cleaning function.

Specifically, as shown in Figure 2, the primary filter frame 101 is used to install and fix the primary filter screen 103; the air or industrial circulating water will pass through the primary filter screen 103 for primary filtration, and then enter the self-cleaning system through the primary filter sleeve 102.
