[0002] Powder covered filter is a kind of filtering equipment, commonly used for liquid processing. Its inner side is divided into a filter chamber and a discharge chamber. The liquid directly enters the inner side of the filter chamber and enters the inner side of the discharge chamber through the filtration of the filter element installed on the inner side of the filter chamber.

[0003] Multiple filter elements need to be installed in the filter chamber. When installing the existing filter elements, the bottom needs to be connected to the through hole connecting the filter chamber and the discharge chamber through threads, and the top needs to be fixed by auxiliary plates, nuts, studs and other structures. This installation method is very inconvenient whether it is disassembly or installation.

[0004] Moreover, in the existing powder covered filtration system, the overflow pipe of the overflow box is much lower than the powder covered filter, which will produce a siphon effect, turbulence inside the powder covered filter, unstable water flow, and uneven membrane laying of the filter element.

[0037] Example 1

[0038] 1 to 5 , a powder-covered filter is provided, comprising a body mechanism 100, including a vessel body 101, a liquid inlet 102 and a liquid outlet 103 provided at the bottom of the vessel body 101, and an overflow port 104 provided at the top of the vessel body 101; liquid enters the inner side of the vessel body 101 through the liquid inlet 102, and the filtered liquid is discharged through the liquid outlet 103. When the liquid level inside the vessel body 101 is too high, the unfiltered liquid is discharged through the overflow port 104.

[0039] The filter element mechanism 200 has one end as a connecting end 201 that can be connected to the tank body 101, and the other end as a stabilizing end 202 away from the connecting end 201; the connecting end 201 is used to fix the filter element mechanism 200 on the inner side of the tank body 101, and the stabilizing end 202 is used to enhance the stability of the filter element mechanism 200 after installation.

[0040] The quick-installation mechanism 300 includes a connecting head 301 provided at the connecting end 201, a positioning member 302 provided on the connecting head 301, and an unlocking member 303 slidably connected to the connecting head 301; and a pre-installed seat mechanism 400 includes a connecting component 401 provided in the vessel body 101, and a locking component 402 provided on the connecting component 401; the positioning member 302 can enter the inner side of the connecting component 401. When the positioning member 302 enters, it only needs to move in the first direction to engage and position with the locking component 402, thereby achieving the effect of quickly installing the filter element mechanism 200 on the inner side of the vessel body 101.

[0041] The unlocking member 303 can be used to unlock the locking component 402 and the positioning member 302 , so that the filter element mechanism 200 can be quickly removed from the tank body 101 during the process of removing the filter element mechanism 200 .

[0042] The locking component 402 can position the positioning member 302 , and the unlocking component 303 can unlock the locking component 402 .

[0043] Specifically, a partition 101a is provided on the inner side of the tank body 101, and the partition 101a divides the internal space of the tank body 101 into a filter chamber 101b and a discharge chamber 101c. The tank body 101 is also provided with a delivery inner tube 101d connected to the filter chamber 101b; the liquid inlet 102 is connected to the delivery inner tube 101d; the liquid outlet 103 is connected to the discharge chamber 101c; the overflow port 104 is provided at the top of the filter chamber 101b; the partition 101a is provided with a through hole 101a-1 connecting the filter chamber 101b and the discharge chamber 101c, and the connecting component 401 is fixed on the partition 101a and corresponds to the position of the through hole 101a-1.

[0044] The external liquid that needs to be filtered enters the inner side of the delivery inner tube 101d through the liquid inlet pipe, and reaches the inner side of the filter chamber 101b through the delivery inner tube 101d. In this embodiment, the filter chamber 101b is located above the discharge chamber 101c. The liquid located on the inner side of the filter chamber 101b enters the built-in filter element mechanism 200 after being filtered by the filter element mechanism 200, and finally enters the inner side of the discharge chamber 101c through the through hole 101a-1. The liquid entering the inner side of the discharge chamber 101c is discharged through the liquid outlet 103.

[0045] The connection end 201 is in an open state, and the liquid entering the inner side of the filter element mechanism 200 can reach the through hole 101a-1 through the connection end 201, and finally enter the inner side of the discharge chamber 101c from the through hole 101a-1.

[0046] In addition, the stabilizing end 202 is in a closed state, which can prevent the unfiltered liquid from entering the inner side of the filter element mechanism 200 .

[0047] The main body of the filter element mechanism 200 is a section of central skeleton material, which is made of stainless steel. The outer side of the central skeleton is covered with a winding wire, which is made of continuous high-strength polypropylene knotted long fiber wire that has been desoaped and deoiled. The liquid inside the filter cabin 101b needs to be filtered by the winding wire before it can enter the inner side of the filter element mechanism 200.

[0048] Furthermore, the connecting head 301 includes a contact sealing body 301a provided at the connecting end 201, an extension column 301b fixed on the sealing body, and an outflow port 301c opened on the contact sealing body 301a; the positioning member 302 has a contact surface 302a capable of pressing the locking member 402, a positioning surface 302b capable of being contacted by the locking member 402, and an outlet 302c passing through the positioning member 302; the locking member 402 includes an elastic member 402a provided on the connecting member 401, and a blocking block 402b provided on the elastic member 402a; when the contact surface 302a contacts the blocking block 402b, it can push the blocking block 402b.

[0049] Among them, the resistance sealing body 301a is truncated cone-shaped, and its outer side is covered with rubber. The extension column 301b is fixed to the end of the resistance sealing body 301a away from the filter element mechanism 200. The liquid inside the filter element mechanism 200 can flow out through the outflow port 301c and enter the inner side of the connecting component 401.

[0050] The positioning member 302 is fixed to the end of the extension column 301b away from the interference sealing body 301a. It is also frustum-shaped, and its annular side wall is the interference surface 302a. The side connected to the extension column 301b is the positioning surface 302b. The liquid entering the inner side of the connecting component 401 can flow through the discharge port 302c and pass through the positioning member 302.

[0051] The blocking block 402b in the locking component 402 has an inclined surface M1 and a parallel surface M2. The inclined surface M1 is located at the end of the blocking block 402b away from the elastic member 402a. The parallel surface M2 can contact the positioning surface 302b to prevent the positioning component 302 from detaching.

[0052] When the positioning member 302 moves toward the first direction on the inner side of the connecting component 401 under the push of the extension column 301b, the resistance surface 302a will resist the inclined surface M1, so that the blocking block 402b gives the elastic member 402a a thrust, causing the elastic member 402a and the blocking block 402b to move away from the axial direction of the connecting component 401. When the resistance surface 302a is separated from the inclined surface M1, the squeezing force of the positioning member 302 on the blocking block 402b disappears. Under the action of the elastic force of the elastic member 402a, the blocking block 402b moves toward the axial direction of the connecting component 401 and resets, thereby achieving the effect of blocking the positioning surface 302b and preventing the positioning member 302 from being separated from the inner side of the connecting component 401.

[0053] In this embodiment, there are two locking parts 402 inside the connecting part 401. When the positioning member 302 moves in the first direction inside the connecting part 401, the contact surface 302a will simultaneously contact the inclined surfaces M1 in the two locking parts 402, and the two locking parts 402 will move away from each other.

[0054] Moreover, there are multiple through holes 101a - 1 starting from the partition 101a , and the specific number can be determined according to the size of the tank body 101 . A connecting component 401 is provided at the position of each through hole 101a - 1 for positioning the filter element mechanism 200 .

[0055] Furthermore, the unlocking member 303 includes a limiting surface 303a capable of pushing the elastic member 402a to move, an abutting end 303b provided at one end of the limiting surface 303a, and a communicating groove 303c provided on the limiting surface 303a.

[0056] The unlocking member 303 is also truncated in shape. The limiting surface 303a is an annular arc surface of its side wall. The contact end 303b is the end of the limiting surface 303a close to the positioning member 302. The unlocking member 303 is slidably sleeved on the extension column 301b. When one of the filter element mechanisms 200 needs to be replaced, the filter element mechanism 200 can be pushed in the first direction, so that the filter element mechanism 200 drives the extension column 301b to push the unlocking member 303 to move in the first direction. The contact end 303b is the end of the limiting surface 303a close to the positioning member 302. 03b will conflict with the inclined surface M1 of the blocking block 402b, causing the two blocking blocks 402b to move away from each other until the two blocking blocks 402b are separated from the conflicting end 303b. Under the action of the elastic member 402a, the elastic member 402a pushes the two blocking blocks 402b to approach each other and conflict with the limiting surface 303a of the unlocking member 303. At this time, under the squeezing of the elastic member 402a and the blocking block 402b, the conflicting end 303b and the positioning surface 302b of the positioning member 302 are fitted.

[0057] Then, the operator needs to pull the filter element mechanism 200 in the second direction, so that the extension column 301b drives the positioning member 302 to move in the second direction. During this process, the positioning surface 302b of the positioning member 302 and the interference end 303b interfere with each other, pushing the unlocking member 303 to move in the second direction. In the process of moving in the second direction, the limiting surface 303a of the unlocking member 303 pushes the blocking blocks 402b away from each other until the interference end 303b and the positioning surface 302b pass between the two blocking blocks 402b, thereby completing the unlocking of the positioning member 302 and the locking component 402.

[0058] The connecting groove 303c provided on the limiting surface 303a is intended to facilitate the passage of liquid. The liquid filtered inside the filter element mechanism 200 passes through the outflow port 301c, the connecting groove 303c, and the outflow port 301c, and finally passes through the through hole 101a-1 and enters the inner side of the discharge chamber 101c.

[0059] The movement in the first direction is movement toward the discharge chamber 101 c , and the second direction is the opposite direction of the first direction.

[0060] With the above solution, when removing the filter element mechanism 200, one only needs to press the filter element mechanism 200 first and then pull the filter element mechanism 200 to remove the filter element mechanism 200. In addition, the size of the abutting end 303b is slightly larger than the size of the positioning surface 302b of the positioning member 302, so that under the action of the abutting end 303b, the positioning member 302 can be more smoothly separated from the locking component 402 when the filter element mechanism 200 is removed.

[0061] The extension column 301b has an adsorption section 301b-1, and the side of the unlocking member 303 facing the adsorption section 301b-1 is an adsorption surface 302d. The unlocking member 303 can be adsorbed on the adsorption section 301b-1 through the adsorption surface 302d, so that when the filter element mechanism 200 is installed, a distance is maintained between the unlocking member 303 and the positioning member 302. When the blocking block 402b contacts the limiting surface 303a of the unlocking member 303, the adsorption surface 302d is separated from the adsorption section 301b-1 under the action of the thrust.

[0062] Furthermore, the connecting component 401 includes a connecting seat 401a, which is fixed on the partition 101a and has a position corresponding to the through hole 101a-1; and also includes a tightening member 401b, which includes a fixed pipe 401b-1 arranged on the connecting seat 401a, a resistance spring 401b-2 arranged on the inner side of the fixed pipe 401b-1, and a resistance ring 401b-3 that resists the resistance spring 401b-2.

[0063] The connecting seat 401a is fixed on the partition 101a. It is an annular structure and is coaxial with the through hole 101a-1. The fixed pipe fitting 401b-1 is fixed on the connecting seat 401a. An inner cavity is provided on the inner side of the fixed pipe fitting 401b-1. The resistance spring 401b-2 is located on the inner side of the inner cavity. One end of the resistance ring 401b-3 extends to the inner side of the cavity and fits into the two side walls of the cavity. When the filter element mechanism 200 moves in the first direction, the resistance seal body 301a will press the resistance ring 401b-3, so that the resistance ring 401b-3 presses the resistance spring 401b-2.

[0064] At the same time, when unlocking is required, the filter element mechanism 200 must first be pushed to move in the first direction. At this time, the resistance ring 401b-3 continues to squeeze the resistance spring 401b-2 under the pressure.

[0065] Operation: The positioning member 302 can enter the inner side of the connecting member 401. Once inside, the positioning member 302 only needs to move in the first direction to engage with the locking member 402, thereby quickly installing the filter element assembly 200 inside the container body 101. The unlocking member 303 can unlock the locking member 402 and the positioning member 302, allowing the filter element assembly 200 to be quickly removed from the container body 101 during removal.

[0066] Example 2

[0067] 1 to 5 and 7, this embodiment is different from the first embodiment in that when the filter element mechanism 200 is damaged, the filter element mechanism 200 needs to be disassembled, and there will be no new filter element mechanism 200 for replacement, so as to avoid the problem of liquid leakage from the through hole 101a-1 corresponding to the disassembled filter element mechanism 200. The filter also includes a self-sealing mechanism 500; it includes a transition pipe 501, which is provided on the partition 101a and is located corresponding to the through hole 101a-1, and its side wall A through opening 501a is provided, and an upper opening 501b is provided at the end thereof close to the through hole 101a-1; a reset component 502 is provided on the inner side of the transition tube 501; a closing block 503 is connected to the reset component 502; when the positioning member 302 and the locking component 402 are engaged, the positioning member 302 can push the closing block 503 to disengage from the upper opening 501b; when the positioning member 302 and the locking component 402 are separated, the reset component 502 can push the closing block 503 to close the upper opening 501b.

[0068] The reset component 502 includes an inner tube 502a fixed on the inner side of the transition tube 501, a reset spring 502b located on the inner side of the inner tube 502a, and a push column 502c that contacts the reset spring 502b. The closing block 503 is connected to the push column 502c and is slidingly connected to the transition tube 501 through a slider and a slide groove structure.

[0069] The liquid entering the discharge chamber 101c from the through hole 101a-1 first enters the inner side of the transition pipe 501 through the upper opening 501b. The liquid entering the inner side of the transition pipe 501 can enter the inner side of the discharge chamber 101c through the through hole 501a.

[0070] When the filter element mechanism 200 is not installed, the closing block 503 closes the upper opening 501b under the push of the return spring 502b. When the filter element mechanism 200 is installed, the positioning member 302 moves in the first direction, pressing the closing block 503, so that the closing block 503 drives the push column 502c to press the return spring 502b, and the closing block 503 and the upper opening 501b are separated.

[0071] When the filter element mechanism 200 is disassembled, the positioning member 302 moves in the second direction, and the pressing force on the closing block 503 disappears. At this time, the return spring 502b drives the closing block 503 to reset through the push column 502c, and the closing block 503 closes the upper opening 501b and the through hole 101a-1, so that after the filter element mechanism 200 is disassembled, the corresponding through hole 101a-1 can be closed, avoiding the problem that the liquid inside the filter chamber 101b leaks into the discharge chamber 101c without being filtered.

[0072] In order to improve stability, a hole groove corresponding to the inner groove of the transition tube 501 is opened on the inner side of the through hole 101a-1. Under the push of the return spring 502b, the closing block 503 can enter the inner side of the through hole 101a-1 and close the through hole 101a-1.

[0073] Specifically, an auxiliary positioning member 101e is also provided on the inner side of the tank body 101, and the auxiliary positioning member 101e includes an auxiliary plate 101e-1 fixed on the inner side of the tank body 101, a through hole 101e-2 opened on the auxiliary plate 101e-1, a guide tube 101e-3 fixed on the auxiliary plate 101e-1, and a limit block 101e-4 on the inner side of the guide tube 101e-3; the stabilizing end 202 is provided with a guide plate 202a, a coaxial column 202b is provided on the guide plate 202a, and a rotatable limit plate 202c is provided on the outer side of the coaxial column 202b; the limit block 101e-4 can be clamped with the limit plate 202c.

[0074] The purpose of the auxiliary positioning member 101e is to avoid the problem of accidental separation of the filter element mechanism 200. The auxiliary positioning member 101e is provided. The auxiliary plate 101e-1 is fixed on the inner side of the tank body 101 and passes through the auxiliary plate 101e-1 through the hole 101e-2. The guide tube 101e-3 is fixed to the side of the auxiliary plate 101e-1 close to the through hole 101a-1. A side groove 202a-1 is provided on the guide plate 202a to allow the limit block 101e-4 to pass through. A type wheel 202b-1 is provided on the outer side of the coaxial column 202b. The limit plate 202c is rotatably sleeved on the outer side of the type wheel 202b-1. The side wall of the limit plate 202c is provided with a limiting groove 202c-2, and a through port 202c-1 is provided on the limit plate 202c.

[0075] When connecting the filter element mechanism 200, the filter element mechanism 200 as a whole passes through the through hole 101e-2. When the positioning mechanism enters the inner side of the connecting component 401, the limiting plate 202c enters the inner side of the guide tube 101e-3. The diameter of the limiting plate 202c is adapted to the inner diameter of the guide tube 101e-3. After the limiting plate 202c enters the inner side of the guide tube 101e-3, it can play a certain guiding role for the entire filter element mechanism 200, so that the positioning member 302 can stably enter the inner side of the connecting component 401.

[0076] When the limit plate 202c moves toward the first direction on the inner side of the guide tube 101e-3, the limit block 101e-4 can pass through the guide plate 202a through the side groove 202a-1. When the positioning member 302 and the locking member 402 are engaged, the limit block 101e-4 reaches the limit groove 202c-2 from the through port 202c-1. At this time, rotating the limit plate 202c can make the limit block 101e-4 reach the inner side of the limit groove 202c-2. At this time, the filter element mechanism 200 can be limited, making the filter element mechanism 200 unable to move, thereby avoiding the problem of accidental detachment caused by accidental movement of the filter element mechanism 200.

[0077] The rest of the structure is the same as that of Example 1.

[0078] Operation process: When the filter element mechanism 200 is disassembled, the positioning member 302 moves in the second direction, and the pressing force on the closing block 503 disappears. At this time, the return spring 502b drives the closing block 503 to reset through the push column 502c, and the closing block 503 closes the upper opening 501b and the through hole 101a-1, so that after the filter element mechanism 200 is disassembled, the corresponding through hole 101a-1 can be closed, avoiding the problem that the liquid inside the filter chamber 101b leaks into the discharge chamber 101c without being filtered.

[0079] Example 3

[0080] 1 to 8 , this embodiment is different from the above embodiments in that, in order to prevent the filter element mechanism 200 from rotating and to improve the stability of the filter element mechanism 200 , the filter further includes an anti-rotation mechanism 600 ; the mechanism includes an outer ring 601 , which is arranged on the outside of the connecting head 301 ; an elastic shaft 602 , which is arranged on the side wall of the outer ring 601 ; a snap-fit ​​piece 603 , which is slidably arranged on the elastic shaft 602 ; when the positioning member 302 and the locking component 402 are engaged, the snap-fit ​​piece 603 can be engaged with the elastic member 402 a , and after the snap-fit ​​piece 603 and the elastic member 402 a are engaged, the filter element mechanism 200 can be prevented from rotating, thereby avoiding the problem of instability of the filter element mechanism 200 caused by rotation.

[0081] Specifically, the elastic member 402a includes a transverse column 402a-1 that is slidably arranged on the connecting seat 401a, and a first spring 402a-2 that is sleeved on the outside of the transverse column 402a-1 and contacts the blocking block 402b; the transverse column 402a-1 passes through the connecting seat 401a, and the blocking block 402b is located at one end on the inner side of the connecting seat 401a. The first spring 402a-2 is used to provide thrust to the blocking block 402b. The end of the transverse column 402a-1 away from the blocking block 402b extends to the outside of the connecting seat 401a. When the positioning member 302 and the locking component 402 are locked, the locking piece 603 can be locked on the outside of the transverse column 402a-1, thereby preventing the filter element mechanism 200 from rotating.

[0082] The elastic shaft 602 includes an outer shaft body 602a fixed on the outer ring 601, an anti-separation piece 602b sleeved on the outer shaft body 602a, and a second spring 602c sleeved on the outside of the outer shaft body 602a and in contact with the anti-separation piece 602b. The snap-fit ​​piece 603 is slidably sleeved on the outside of the outer shaft, and the snap-fit ​​piece 603 cannot rotate on the outside of the outer shaft body 602a. This can be achieved by slotting the outer shaft body 602a and providing a guide protrusion on the inside of the snap-fit ​​piece 603.

[0083] In the natural state, the second spring 602c presses the snap-fit ​​piece 603 toward the center of the connecting seat 401a. A chamfered surface 401a-1 is provided on the connecting seat 401a. When the positioning member 302 moves in the first direction, the end of the snap-fit ​​piece 603 will contact the chamfered surface 401a-1, causing the snap-fit ​​piece 603 to move away from the center of the connecting seat 401a, thereby squeezing the second spring 602c and causing the second spring 602c to deform.

[0084] At the same time, an alignment groove is opened on the chamfered surface 401a-1 at the corresponding position of the transverse column 402a-1. The end of the alignment groove close to the transverse column 402a-1 is the contraction end N1, and the end away from the transverse column 402a-1 is the expansion end N2. From the expansion end N2 to the contraction end N1, the width of the alignment groove gradually shrinks. Under the guidance of the alignment groove, the snap-fit ​​piece 603 can be more accurately aligned with the transverse column 402a-1.

[0085] The rest of the structure is the same as that of Example 2.

[0086] Operation process: When the positioning member 302 and the locking component 402 are engaged, the locking piece 603 can be engaged on the outside of the transverse column 402a-1, thereby preventing the filter element mechanism 200 from rotating. When the positioning member 302 moves in the first direction, the end of the locking piece 603 will contact the chamfered surface 401a-1, causing the locking piece 603 to move away from the center of the connecting seat 401a. Under the guidance of the alignment groove, the locking piece 603 can be more accurately aligned with the transverse column 402a-1.

[0087] Example 4

[0088] 9 , this embodiment is different from the above embodiments in that: the present invention also proposes a filtration system, including the powder-covered filter in the above embodiment; it includes a dissolution box 1000, which is connected to the liquid inlet 102, and a film-laying pump 1001 is provided between the dissolution box 1000 and the liquid inlet 102. The dissolution box 1000 is built-in with a mixed suspension containing particulate impurities and dissolved iron impurities discharged from the air-cooling island, and the mixed suspension is transported to the inner side of the filter by the film-laying pump 1001 for filtration.

[0089] The filter further includes an overflow box 2000 , which is connected to the overflow port 104 . When the liquid level inside the filter is too high, the liquid flows into the inside of the overflow box 2000 through the overflow port 104 .

[0090] In order to avoid the overflow pipe 3000 of the overflow box 2000 being far lower than the powder-covered filter, which would produce a siphon effect and cause turbulence inside the powder-covered filter and unstable liquid flow, the system is also equipped with an overflow pipe 3000, which is connected to the overflow box 2000 and whose height is not lower than the tank body 101.

[0091] The rest of the structure is the same as that of Example 3.

[0092] Operation process: By raising the height of the overflow pipe 3000, the overflow box 2000 and the overflow pipe 3000 can be raised to a liquid level not lower than the tank body 101, thereby avoiding the siphon effect that causes water to continuously flow to the overflow box 2000, causing powder to cover the inside of the filter and causing turbulence. At the same time, an exhaust hole 3001 is opened at the top of the overflow pipe 3000 to avoid the overflow pipe 3000 itself from generating a siphon effect, so that the overflow box 2000 can reach a full load state.
