Description

Water filtering dust collector

Technical Field

The invention relates to a dust separation device of a dust collector, in particular to a dust collector which removes dust from air by using a water medium.

Background

Dust in a traditional dust collector can only be filtered through a dust bag filtering device or a filter element, the dust bag and the filter element are easy to block and wear, and the dust bag and the filter element are frequently cleaned or replaced, so that great waste is caused. The existing water filtering dust collector has different advantages and disadvantages corresponding to the following three different schemes due to unreasonable structural design:

scheme 1, see patent application CN200720309205, water filtration dust collector.

The scheme is characterized in that: the outlet of the suction pipe is arranged below the water surface, and the direction of the air outlet is downward, namely the air flow is blown out downwards from the water.

The advantages are that: air and water are vigorously stirred, the mixing effect is good, and the dust removal effect is good when the operation is started.

The disadvantages are as follows:

1) the outlet of the suction pipe is below the water surface, the air flow rate is high, the relative speed when the suction pipe is contacted with water is high, and water mist is easily generated.

2) All water moves at high speed along with air, the kinetic energy of the water is finally changed into heat energy to be dissipated, and the energy consumption of the water is high, so that the suction force of the dust collector is poor and the energy consumption is high.

3) The high-speed airflow impacts the bottom of the water tank downwards, all water is quickly stirred, all water bodies are turbid, the turbid water cannot meet the requirement of clean air quickly along with the increase of dust, and the dust collection operation cannot be continued.

4) The high-speed air current strikes the bottom in pond downwards, and the air current is torn into tiny bubble, needs longer time just can follow aquatic and separates out, and in addition, this leads to the whole foaminess that becomes of aqueous solution, and the surface of water height is showing, and the whole height of dust catcher is limited, and the water gets into the motor very easily or discharges outside the dust catcher through the fan.

Scheme 1 has essentially no practical value and has been eliminated by the market.

Scheme 2, CN201621298322, a water filtration cleaner:

the scheme is characterized in that: the outlet of the suction pipe is arranged below the water surface and close to the water surface, and the direction of the air outlet is upward, namely the air flow is blown out upward from the water.

The advantages are that: the garbage is deposited on the lower layer of water under the action of gravity, the water on the upper layer is relatively cleaner, and the water for filtering the air is relatively cleaner because the air is only stirred and mixed with the water on the upper layer and the flow rate of the water on the lower layer is very low or even static. Compared with scheme 1, the air bubbles only exist in the upper layer of the water, the water is not easy to become in an integral foam state, and the liquid level height of the water is relatively stable.

The disadvantages are as follows:

1) the straw export is below the surface of water, and air flow rate is high, and relative speed when contacting with water is big, produces the water smoke very easily to cause the splash to splash everywhere, the high-speed air current is easy to bring the drop of water and the water smoke that splash into the motor, causes motor trouble, also can bring a large amount of water smoke into the air exit simultaneously, the influence is used.

2) The high-speed airflow is upwards ejected from the water close to the water surface at a high speed, the contact time of the air and the water is very short, the air flow field is cylindrical, the contact of the surrounding air and the water is sufficient, but the contact of the airflow at the center of the cylinder and the water is insufficient, some dust cannot contact the water, the dust directly rises along the airflow, and then the dust is discharged out of the dust collector through the centrifugal fan, so that the water filtering effect is poor.

3) In order to inhibit the rising of water drops, a water baffle must be arranged on the rising path of the air flow, but the water baffle with a simple structure has a poor water baffle effect, and on the contrary, the water baffles with good water baffle effect have complex structures and high cost, and obviously increase the air flow resistance, thus causing poor suction force of the dust collector.

4) Because the garbage bin needs to be detached to clean after the operation is finished, the garbage bin, an air pipeline in the garbage bin, a water baffle and the like need to be made into a split type, the air channel between the air pipeline and the wall of the garbage bin needs to be sealed, and the problems that the parts of the water filtering module are complex in structure, high in manufacturing cost, inconvenient to disassemble and assemble, difficult to clean and the like are caused by the requirements.

5) If absorb water with this kind of dust catcher, then the water level height rises in the garbage bin, and the air outlet of intake duct will be followed and is kept away from the surface of water continuously from being close to the surface of water position, will take place similar scheme 1's effect, promptly, the water inside dissolves a large amount of bubbles and is difficult to separate out fast, and the water becomes the foaminess and leads to the water level to increase fast, and water gets into the motor very easily or flies out the dust catcher through the fan. Compared with a dust bag type dust collector or a filter bucket type dust collector with the same volume of the garbage can, the water filtering dust collector adopting the scheme 2 has much smaller water absorption capacity.

The mainstream water filtering dust collector in the market at present adopts the scheme.

Solution 3, CN201621298669, a water filtration vacuum cleaner with a cyclone mixing device:

the scheme is characterized in that: the outlet of the suction pipe is arranged below the water surface and close to the water surface, and the air outlet blows out horizontally to promote the water body to rotate in the horizontal plane direction.

The advantages are that:

1) compared with the scheme 2, the air and water have a horizontal rotating mixing effect, the relative speed difference of the air and the water is smaller, and the phenomenon of splashing of water is weakened; the contact time of the air and the water is longer, and the filtering and cleaning effect of the water on the air is better.

2) Similar with scheme 2, the air outlet of intake duct is close to the surface of water, and the bubble only exists in the upper strata of water, and water is difficult to become whole foam state, and the liquid level height of water is relatively stable.

The disadvantages are as follows:

1) similar with scheme 2, the straw export is below the surface of water, and air flow rate is high, and relative speed when contacting with water is big, produces the water smoke very easily to cause the splash to splash, high-speed air current is easy to bring the drop of water and the water smoke that splash into the motor, causes motor trouble, also can bring a large amount of water smoke out the air exit simultaneously, influences the use.

2) Similar to scheme 2, these components for water filtration still need to be separated and ensure the air channel of the air pipeline and the garbage can wall to be sealed, and these requirements lead to the problems of complex structure, high manufacturing cost, inconvenient assembly and disassembly, difficult cleaning and the like of the components of the water filtration module.

3) Similar to scheme 2, compared with a dust bag type dust collector or a filter bucket type dust collector with the same volume of the garbage can, the water-filtering dust collector adopting scheme 3 has much smaller water-absorbing capacity.

4) The air outlet of the air inlet channel is arranged below the water surface, and in order to realize the rotating effect of water, the air outlet overflowing area of the air inlet channel cannot be too large, so that the relative speed of air and water is still high, and the phenomenon of obvious splash of water can still occur.

Summarizing all 3 of the above solutions, there is a fundamental problem: the relative velocity of air and water is high when they come into contact, which leads to two disadvantages:

first, the water is easily broken into fine droplets and mist that can easily follow the airflow to the inside of the motor or fly to the outside of the cleaner by the fan.

Second, according to the theorem on kinetic energy, kinetic energy is equal to the mass times the square of the velocity, i.e., the kinetic energy of water is proportional to the velocity of water. The greater the velocity of the air stream in contact with the water, the greater the velocity and kinetic energy of the water; the energy of the water cannot be used for dust collection, and the water is wasted, so that the suction force of the dust collector is poor, and the energy consumption is high.
