Description

Technical Field

[0001] The utility model relates to the field of air filtering equipment, in particular to an air filtering device for a machine room air conditioner. Background Art

[0002] When the air conditioner is used in the computer room, it is to cool the electronic components in the computer room. The existing air conditioner is installed on the chassis in the computer room, and the air is taken in by the air conditioner through the air inlet on the chassis, and then filtered by the filter element of the air conditioner.

[0024] This embodiment discloses an air filter device for a computer room air conditioner, which can play a good role in filtering gas when the computer room air conditioner is in operation, thereby improving the overall practicality of the air filter device.

[0025] See also Figure 1-Figure 5 This embodiment includes a supporting shell 1, and three chambers are arranged in a straight line from left to right inside the supporting shell 1, which are an air intake chamber 2, a first filter chamber 3 located on the right side of the air intake chamber 2, and a second filter chamber 4 located on the right side of the first filter chamber 3.

[0026] The interior of the air inlet bin 2 is divided into an upper chamber and a lower chamber by a horizontal partition. The lower chamber of the air inlet bin 2 is a storage bin 30, through which tools can be stored for convenient use. A closing door is installed on the side wall of the support housing 1 corresponding to the position of the storage bin 30, and dust can be prevented from entering the interior of the storage bin 30.

[0027] An air inlet 25 is provided at the top of the support shell 1 corresponding to the position of the air inlet bin 2, through which external gas can enter the upper chamber of the air inlet bin 2. A coarse filter 26 is provided inside the air inlet 25, and the coarse filter 26 can be used to simply filter the gas entering the upper chamber of the air inlet bin 2, thereby reducing the pressure of the first filter bin 3 and the second filter bin 4 behind. An air pump 27 is provided in the upper chamber of the air inlet bin 2, and the air inlet end of the air pump 27 leads to the interior of the upper chamber of the air inlet bin 2 through an air suction pipe 28, and the air outlet end of the air pump 27 is connected to an air jet pipe 29, which penetrates into the interior of the first filter bin 3.

[0028] The first filter chamber 3 contains filtered water, and the jet pipe 29 penetrates the first filter chamber 3 and extends downward to below the liquid level of the filtered water. When the vacuum pump 27 is started, the gas in the upper chamber of the air inlet chamber 2 can be introduced into the jet pipe 29 through the vacuum pipe 28, and then introduced into the filtered water through the jet pipe 29, and then the filtered water in the first filter chamber 3 is used to reduce dust on the gas.

A horizontal rotating shaft 24 is also rotatably installed in the first filter bin 3, and a longitudinal bevel gear 23 is coaxially fixed to one end of the rotating shaft 24. The longitudinal bevel gear 23 is in transmission meshing with the transverse bevel gear 22. The other end of the rotating shaft 24 extends to the outside of the first filter bin 3 and is installed with a crank. Turning the crank can drive the rotating shaft 24 to rotate, and then drive the screw rod 20 to rotate through the longitudinal bevel gear 23 and the transverse bevel gear 22.

[0030] A fine filter 19 is provided in the first filter chamber 3. The initial position of the fine filter 19 is located at the bottom of the first filter chamber 3, that is, the fine filter 19 is initially located below the liquid level of the filtered water and submerged by the filtered water. One side of the fine filter 19 is screwed on the screw rod 20 through a threaded hole, and the other side of the fine filter 19 is slidably installed on the slide bar 21 through a light hole.

When the fine filter 19 rises to a level higher than the liquid level of the filtered water, it can take away impurities formed in the filtered water after the gas enters the filtered water, thereby cleaning the impurities in the filtered water. A lid that can be opened and closed is installed on the top of the support shell 1 corresponding to the position of the first filter chamber 3. When the lid is opened, impurities on the fine filter 19 can be removed to clean and maintain the fine filter 19.

The water spray pipe 18 is extended to the top of the first filter bin 3. A nozzle is provided at the pipe end of the water spray pipe 18 located at the top of the first filter bin 3. The filtered water can be introduced into the inside of the nozzle through the circulation pump 17, and then sprayed into the first filter bin 3 through the nozzle, thereby spraying and reducing dust on the gas in the first filter bin 3. A connecting pipe is provided between the first filter bin 3 and the second filter bin 4. The left end of the connecting pipe leads to the first filter bin 3, and the right end of the connecting pipe leads to the left position in the second filter bin 4.

The right shell wall of the supporting shell 1 is provided with an air outlet corresponding to the position of the last filter screen in the second filter chamber 4, i.e., the post-activated carbon filter screen 8. The PP cotton filter screen 5, the granular activated carbon filter screen 6, the hollow fiber ultrafiltration membrane filter screen 7 and the post-activated carbon filter screen 8 are each plugged and installed in the second filter chamber 4 through the corresponding connecting plate 9.

[0033] Specifically, a positioning column 16 is fixed to the bottom frame edge of each connecting plate 9, and a positioning hole is provided at the bottom of the second filter chamber 4 corresponding to the position of the positioning column 16 of each connecting plate 9. When the connecting plate 9 is inserted downward into the second filter chamber 4, the positioning column 16 is inserted into the positioning hole at the corresponding position of the bottom of the second filter chamber 4, thereby achieving positioning.

[0034] Four insertion ports are provided on the top of the second filter bin 4 from left to right, and each connection plate 9 is a rectangular frame. The PP cotton filter 5, the granular activated carbon filter 6, the hollow fiber ultrafiltration membrane filter 7 and the post-activated carbon filter 8 are fixed in their corresponding connection plates 9. The four connection plates 9 are inserted into the second filter bin 4 through the insertion ports on the top of the second filter bin 4 from top to bottom.

[0035] See also Figure 1-Figure 4 , a receiving groove 11 is provided in the top frame edge of each connecting plate 9, and the receiving groove 11 penetrates the connecting plate 9 in the left-right direction. A pair of left-right distributed bayonet pins 12 are installed in the receiving groove 11, and each bayonet pin 12 can slide in the receiving groove 11 along the left-right horizontal direction. The right end of the left bayonet pin 12 and the left end of the right bayonet pin are opposite to each other, and the right end of the left bayonet pin 12 and the left end of the right bayonet pin are respectively set as ball head ends, and the left end of the left bayonet pin 12 can pass through the left side wall of the top frame edge of the connecting plate 9, and the right end of the right bayonet pin 12 can pass through the right side wall of the top frame edge of the connecting plate 9. A pair of left-right distributed limiting grooves 13 are also provided in the top frame edge of the connecting plate 9 above the receiving groove 11, and the two limiting grooves 13 are respectively connected to the receiving groove 11, and the two bayonet pins 12 respectively have upward extension parts, and the extension parts of the two bayonet pins 12 extend into the two limiting grooves 13 one by one. A horizontal return spring 14 is also disposed in each limiting groove 13 , one end of the return spring 14 is fixed to the extension of the corresponding latch 12 , and the other end of the limiting spring 14 is fixed to the groove wall of the limiting groove 13 .

[0036] A vertical threaded hole 10 is provided at the top frame edge of each connecting plate 9 corresponding to the middle position of the receiving groove 11. The upper end opening of the threaded hole 10 is located on the top surface of the top frame edge of the connecting plate 9, and the lower end opening of the threaded hole 10 is connected to the middle position of the receiving groove 11. A fixing rod 15 is screwed in the threaded hole 10. The upper end of the fixing rod 15 is located above the top frame edge of the connecting plate, and the lower end of the fixing rod 15 can extend into the receiving groove 11. The threaded hole 10, the receiving groove 11, the latch 12, the limit groove 13, the return spring 14, and the fixing rod 15 constitute a spring pin mechanism.

[0037] When each connecting plate 19 is inserted and installed in the second filter bin 4, the fixing rod 15 is rotated so that the fixing rod 15 extends downward into the interior of the receiving groove 11 and squeezes into the ball heads of the two bayonet pins 12 that are opposite to each other, thereby making the two bayonet pins 12 slide in opposite directions, wherein the left bayonet pin 12 slides to the left and the right bayonet pin 12 slides to the right. When the left bayonet pin 12 slides to the point where its left end passes through the left side wall of the top frame edge of the connecting plate 9 and the right bayonet pin 12 slides to the point where its right end passes through the right side wall of the top frame edge of the connecting plate 9, the protruding ends of the two bayonet pins 12 respectively abut against the mouth wall of the corresponding insertion port of the second filter bin 4, thereby making the corresponding connecting plate 19 and the filter screen installed thereon integrally fixed in the second filter bin 4, at which time each reset spring 14 is elastically deformed. When the filter needs to be removed, the fixing rod 15 is rotated to move out of the threaded hole 10, and the corresponding latch 12 can be reset through the reset spring 14, so that the connection between the connecting plate 9 and the second filter chamber 4 is disconnected, making it convenient to take out each connecting plate 9 and the filter inside it as a whole for cleaning and maintenance.

[0038] Therefore, in this embodiment, the connecting plates 9 of the PP cotton filter 5, the granular activated carbon filter 6, the hollow fiber ultrafiltration membrane filter 7 and the post-activated carbon filter 8 can be fixed in the second filter chamber 4 by a spring pin mechanism.
