Problems solved by technology

However, the filter chip of the traditional air filter will cause dust to accumulate on the filter net, which is inconvenient to clean. If it is not cleaned in time, it will cause secondary pollution. Therefore, it is difficult to accept traditional air filters in areas with serious dust pollution.

Embodiment 1

[0023] Such as figure 1 As shown, the first embodiment includes at least one set of unit air filters and intermittent wind-shielding devices, and the unit air filters are arranged in a ring to form an air filter with airflow radially entering and axially exiting.

[0024] Such as figure 2 As shown, the unit air filter includes several guide grooves and deflector brackets 2, and the guide grooves are composed of a front guide groove 10 and a rear guide groove 8, and the air outlet of the front guide groove 10 The end face is a left slanted end face, the air inlet end face of the rear diversion groove 8 is a right slanted end face, the front diversion groove 10 and the rear diversion groove 8 are inwardly inclined and arranged in a "V" shape, The air outlet of the front guide groove 10 and the air inlet of the rear guide groove 8 are misplaced and interleaved, that is, the upper and lower guide plates 11, 13 of the front guide groove 10 and the rear guide groove 8 The upper a...

Embodiment 2

[0028] Such as Figure 3-Figure 6 As shown, the second embodiment includes at least one set of unit air filters and intermittent wind-shielding devices. The unit air filters are arranged in a straight line to form an air filter with airflow radially inward and radially outward.

[0029] The specific structure inside the unit air filter is the same as that in Embodiment 1, and will not be described here again.

[0030] Another example image 3 , Figure 4 As shown, the intermittent windshield device includes a mobile windshield 3 and a motor transmission mechanism 7, and the motor transmission mechanism 7 converts the motor rotation into a reciprocating linear motion, thereby driving the mobile windshield 3 to reciprocate linearly, Realize intermittent wind-shielding and exhausting.

[0031] The working process of the second embodiment is basically the same as that of the first embodiment, and will not be described again.

Embodiment 3

[0033] Such as Figure 7-Figure 8 As shown, the difference between the third embodiment and the second embodiment is that the diversion tank is composed of the front, middle and rear three diversion tanks, and its core is to add another stage of water curtain filtration on the basis of the second embodiment Channel, the middle guide groove 14 is an arc-shaped structure or "∧" shape structure, the air outlet of the front guide groove 10 and the air inlet of the middle guide groove 14 are misplaced and interleaved to form the first The first-stage water curtain filtering channel, the air outlet of the middle diversion groove 14 and the air inlet of the rear diversion groove 8 are misplaced and interleaved to form a second-stage water curtain filtering channel.

[0034] Its working process is basically the same as that of Embodiment 2, and will not be elaborated here.

Abstract

The invention relates to an air filter and particularly relates to a water curtain type air filter which is used in cooperation with a fan and adopts a liquid as a filter medium. The air filter comprises at least one group of air filter unit, wherein one air filter unit comprises multiple guide grooves and a guide plate bracket and is characterized in that each guide groove is composed of a front guide groove and a rear guide groove; the air outlet of the front guide groove and the air inlet of the rear guide groove are intersected in a staggered manner, so as to form a water curtain filter channel; and an intermittent air blocking device is arranged at one side of the outlet of the rear guide groove. The invention aims to design the water curtain type air filter capable of filtering dust in air flow containing dust with a liquid. Compared with the prior art, the water curtain type air filter has the advantage of good filter effect, large air filter capacity and low production cost and is applicable to filtering occasions in which air radially enters and axially leaves.

Description

technical field [0001] The invention relates to an air filter, in particular to a water curtain air filter which is used in conjunction with a fan and uses liquid as a filter medium. Background technique [0002] At present, the air filter is a conventional and necessary filter device used in conjunction with the fan, and is widely used in various fields of air purification, especially in dust-polluted workshops such as cement plant manufacturing workshops. However, the filter chip of the traditional air filter will cause dust to accumulate on the filter screen, which is inconvenient to clean. If it is not cleaned in time, it will cause secondary pollution. Therefore, it is difficult to accept traditional air filters in areas with serious dust pollution. Contents of the invention [0003] The purpose of the present invention is to design a water curtain air filter capable of dust-filtering dust-laden airflow with liquid. [0004] In order to achieve the above object, the ...
