Description

[Technical Field]

[0001] The present invention relates to the field of filters, and more particularly to powder precoated filters and filtration systems thereof. [Background technology]

[0002] A powder precoat filter is a filtering device commonly used in liquid processing, and has a filtering chamber and a discharge chamber inside. The liquid directly enters the filtering chamber, is filtered by the filter element installed inside the filtering chamber, and then enters the discharge chamber.

[0003] Multiple filter elements need to be installed within the filtration chamber. When installing existing filter elements, the lower part needs to be connected with a screw to a through-hole connecting the filtration chamber and the discharge chamber, and the upper part needs to be fixed with a structure such as an auxiliary plate, nut, or stud. This installation method is very inconvenient for both removal and installation.

[0004] Furthermore, in existing powder precoat filter systems, the overflow pipe of the overflow box is located much lower than the powder precoat filter, which causes a siphoning phenomenon and turbulence inside the powder precoat filter, making the water flow unstable and resulting in an uneven film covering the filter element.

DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make the above objects, features and advantages of the present invention more clear and understandable, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

[0023] Numerous specific details are set forth below to facilitate a thorough understanding of the present invention; however, the present invention may be practiced in other ways than those described herein, and similar extensions may be made by those skilled in the art without departing from the spirit of the present invention, and therefore the present invention is not limited by the specific examples disclosed below.

[0024] Also, as used herein, "one embodiment" or "embodiment" refers to a particular feature, structure, or characteristic that may be included in at least one embodiment of the present invention. The appearances of the phrase "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they mutually exclusive embodiments separate or alternative from other embodiments.

[0025] Furthermore, the present invention will be described in detail in conjunction with schematic drawings, and when describing the embodiments of the present invention in detail, for ease of explanation, the cross-sectional views showing the structure of the device are partially enlarged and not according to the normal scale, and the schematic drawings are merely illustrative and do not limit the scope of protection of the present invention, and should include three-dimensional spatial dimensions of length, width and depth during actual production.

[0026] Example 1 1 to 5, a powder precoated filter is provided, the powder precoated filter comprising a container body mechanism 100, a filter element mechanism 200, a quick-assembly mechanism 300, and an assembled seat mechanism 400, the container body mechanism 100 having a container body 101, a liquid inlet 102 and a liquid outlet 103 provided at the bottom of the container body 101, and an overflow port 104 provided at the top of the container body 101, wherein liquid enters the inside of the container body 101 through the liquid inlet 102, is filtered, and is discharged from the liquid outlet 103, and when the liquid level inside the container body 101 becomes too high, unfiltered liquid is discharged from the overflow port 104.

[0027] The filter element mechanism 200 has a connecting end 201 connectable to the container body 101 and a stable end 202 spaced from the connecting end 201, the connecting end 201 being used to fix the filter element mechanism 200 inside the container body 101, and the stable end 202 being used to increase the stability of the filter element mechanism 200 after installation.

[0028] The quick assembly mechanism 300 has a communicating head 301 provided on the connecting end 201, a positioning member 302 provided on the communicating head 301, and an unlocking member 303 slidably connected to the communicating head 301, and the assembled seat mechanism 400 has a communicating part 401 provided in the container body 101 and a locking part 402 provided on the communicating part 401, and the positioning member 302 can enter the inside of the communicating part 401, and when the positioning member 302 enters, it only needs to move in the first direction to be engaged with and restricted by the locking part 402, thereby achieving the effect of quickly attaching the filter element mechanism 200 to the inside of the container body 101.

[0029] The lock release member 303 can release the lock between the locking part 402 and the positioning member 302, so that the filter element mechanism 200 can be quickly removed from the container body 101 during the process of removing the filter element mechanism 200.

[0030] The locking part 402 can restrict the positioning member 302 , and the unlocking member 303 can unlock the locking part 402 .

[0031] Specifically, a partition plate 101a is provided inside the container body 101, and the internal space of the container body 101 is divided into a filtration chamber 101b and a discharge chamber 101c by the partition plate 101a. The container body 101 is further provided with an inner conveying pipe 101d that is connected to the filtration chamber 101b, a liquid inlet 102 is connected to the inner conveying pipe 101d, a liquid outlet 103 is connected to the discharge chamber 101c, and an overflow port 104 is provided at the top of the filtration chamber 101b. A through hole 101a-1 that connects the filtration chamber 101b and the discharge chamber 101c is opened in the partition plate 101a, and a communication part 401 is fixed to the partition plate 101a and corresponds to the position of the through hole 101a-1.

[0032] The external liquid to be filtered passes through the liquid inlet pipe into the inside of the conveying inner pipe 101d, passes through the conveying inner pipe 101d and reaches the inside of the filtration chamber 101b. In this embodiment, the filtration chamber 101b is located above the discharge chamber 101c, and the liquid located inside the filtration chamber 101b is filtered by the filter element mechanism 200, then passes into the inside of the filter element mechanism 200, and finally passes through the through hole 101a-1 into the inside of the discharge chamber 101c. The liquid that has passed into the inside of the discharge chamber 101c is discharged from the liquid outlet 103.

[0033] Here, the connection end 201 is in an open state, and liquid that has entered the inside of the filter element mechanism 200 can pass through the connection end 201 to reach the through-hole 101a-1, and finally enter the inside of the discharge chamber 101c from the through-hole 101a-1.

[0034] Additionally, the closed stable end 202 prevents liquid from entering the interior of the filter element assembly 200 unfiltered.

[0035] The main body of the filter element mechanism 200 is a central skeleton made of stainless steel, and a winding made of continuous yarn of degreased and deoiled high-strength polypropylene long fiber yarn is wound around the outside of the central skeleton. Liquid that enters the inside of the filtration chamber 101b must be filtered by the winding before entering the inside of the filter element mechanism 200.

[0036] Furthermore, the communicating head 301 has an abutment seal body 301a provided at the connecting end 201, an extension post 301b provided on the seal body, and an outlet 301c opened in the abutment seal body 301a, and the positioning member 302 has an abutment surface 302a that can press the locking part 402, a positioning surface 302b that can be abutted by the locking part 402, and an outlet 302c that penetrates the positioning member 302, and the locking part 402 has an elastic member 402a provided on the communicating part 401 and a blocking block 402b provided on the elastic member 402a, and when the abutment surface 302a abuts against the blocking block 402b, it can press the blocking block 402b.

[0037] Here, the abutting seal body 301a is in the shape of a circular table, the outside of which is covered with rubber, and the extension post 301b is fixed to one end of the abutting seal body 301a that is away from the filter element mechanism 200, so that the liquid inside the filter element mechanism 200 can flow out from the outlet 301c and enter the inside of the communicating part 401.

[0038] The positioning member 302 also has a circular table shape and is fixed to one end of the extension post 301b away from the abutment seal body 301a, and its annular side wall is the abutment surface 302a, and the side connected to the extension post 301b is the positioning surface 302b, so that liquid that has entered the inside of the communicating part 401 can flow through the positioning member 302 through the outlet 302c.

[0039] The blocking block 402b in the locking part 402 has an inclined surface M1 and a parallel surface M2, and the inclined surface M1 is located at one end of the blocking block 402b away from the elastic member 402a, and the parallel surface M2 abuts against the positioning surface 302b, thereby preventing the positioning member 302 from coming off.

[0040] When the positioning member 302 is pushed by the extension post 301b and moves in a first direction inside the communicating part 401, the abutment surface 302a abuts against the inclined surface M1, and the blocking block 402b applies a pressing force to the elastic member 402a, causing the elastic member 402a and the blocking block 402b to move in an axial direction away from the communicating part 401. After the abutment surface 302a disengages from the inclined surface M1, the pressing force applied by the positioning member 302 to the blocking block 402b disappears, and the elastic force of the elastic member 402a causes the blocking block 402b to move in the axial direction of the communicating part 401 and be reset, thereby achieving the effect of blocking the positioning surface 302b so that the positioning member 302 does not come off the inside of the communicating part 401.

[0041] In this embodiment, the number of locking parts 402 inside the communicating part 401 is two, and when the positioning member 302 moves in a first direction within the communicating part 401, the abutment surface 302a abuts against the inclined surfaces M1 of the two locking parts 402 simultaneously, and the two locking parts 402 are moved in directions away from each other.

[0042] In addition, there are multiple through holes 101a-1 starting from the partition plate 101a, and the specific number can be determined according to the dimensions of the container body 101. At the position of each through hole 101a-1, a communicating part 401 is provided for positioning the filter element mechanism 200.

[0043] Furthermore, the unlocking member 303 has a position limiting surface 303a that moves the elastic member 402a, a contact end 303b provided at one end of the position limiting surface 303a, and a communication groove 303c opened in the position limiting surface 303a.

[0044] The unlocking member 303 also has a circular table shape as a whole, with the position limiting surface 303a being an annular curved surface of its side wall, and the abutting end 303b being one end of the position limiting surface 303a that is close to the positioning member 302. The unlocking member 303 is slidably fitted onto the extension post 301b. When one of the filter element mechanisms 200 needs to be replaced, the filter element mechanism 200 is pushed in a first direction, and the filter element mechanism 200 drives the extension post 301b to move the unlocking member 303 in the first direction. The abutment end 303b abuts against the inclined surface M1 of the blocking block 402b, moving the two blocking blocks 402b away from each other until they are disengaged from the abutment end 303b, and under the action of the elastic member 402a, the elastic member 402a brings the two blocking blocks 402b closer to each other and presses them so that they abut against the position limiting surface 303a of the unlocking member 303. At this time, due to the pressure of the elastic member 402a and the blocking block 402b, the abutment end 303b is attached to the positioning surface 302b of the positioning member 302.

[0045] Next, the operator needs to pull the filter element mechanism 200 in the second direction so that the extension post 301b moves the positioning member 302 in the second direction, and in the process, the positioning surface 302b of the positioning member 302 abuts against the abutment end 303b, moving the unlocking member 303 in the second direction, and when the position limiting surface 303a of the unlocking member 303 moves in the second direction, the abutment end 303b and the positioning surface 302b push the blocking blocks 402b away from each other until they pass between the two blocking blocks 402b, thereby unlocking the positioning member 302 and the locking part 402.

[0046] The communicating groove 303c opened in the position limiting surface 303a is intended to facilitate the passage of liquid, and the liquid filtered inside the filter element mechanism 200 passes through the outlet 301c, the communicating groove 303c, and the outlet 301c, and finally passes through the through hole 101a-1 to enter the inside of the discharge chamber 101c.

[0047] Here, the movement in the first direction is a movement in a direction approaching the discharge chamber 101c, and the second direction is a direction opposite to the first direction.

[0048] With the above solution, in the process of removing the filter element mechanism 200, it is possible to remove the filter element mechanism 200 simply by first pressing the filter element mechanism 200 and then pulling the filter element mechanism 200. Furthermore, by making the dimension of the abutting end 303b slightly larger than the dimension of the positioning surface 302b of the positioning member 302, the positioning member 302 can be more smoothly released from the locking part 402 when removing the filter element mechanism 200 by the action of the abutting end 303b.

[0049] The extension post 301b has an adsorption portion 301b-1, and one side of the unlocking member 303 facing the adsorption portion 301b-1 is an adsorption surface 302d, and the unlocking member 303 can be adsorbed to the adsorption portion 301b-1 through the adsorption surface 302d, thereby maintaining the distance between the unlocking member 303 and the positioning member 302 when the filter element mechanism 200 is installed, and when the blocking block 402b abuts against the position limiting surface 303a of the unlocking member 303, the adsorption surface 302d comes off the adsorption portion 301b-1 due to the pressing force.

[0050] Furthermore, the communication part 401 has a connection sheet 401a, which is fixed to the partition plate 101a and whose position corresponds to the through hole 101a-1, and further includes a push-up member 401b, which includes a fixed pipe member 401b-1 provided on the connection sheet 401a, an abutment spring 401b-2 provided inside the fixed pipe member 401b-1, and an abutment ring 401b-3 abutting against the abutment spring 401b-2.

[0051] The connecting sheet 401a is fixed to the partition plate 101a, has a ring-shaped structure, and is coaxial with the through hole 101a-1. The fixed pipe member 401b-1 is fixed to the connecting sheet 401a. An internal cavity is provided inside the fixed pipe member 401b-1. The abutment spring 401b-2 is located inside the internal cavity. One end of the abutment ring 401b-3 extends into the cavity and is attached to two side walls of the cavity. When the filter element mechanism 200 moves in the first direction, the abutment seal body 301a presses the abutment ring 401b-3, causing the abutment ring 401b-3 to be pressed by the abutment spring 401b-2.

[0052] At the same time, when it is necessary to release the lock, it is first necessary to continue to press the filter element mechanism 200 in the first direction, and at this time, the abutment ring 401b-3 continues to press the abutment spring 401b-2 with a pressing force.

[0053] During operation, the positioning member 302 can be inserted into the communication part 401, and when the positioning member 302 is inserted, it only needs to move in the first direction to be engaged with and restricted by the locking part 402, thereby achieving the effect of quickly attaching the filter element mechanism 200 to the inside of the container body 101. The lock release member 303 can release the lock between the locking part 402 and the positioning member 302, so that during the process of removing the filter element mechanism 200, the filter element mechanism 200 can be quickly removed from the container body 101.

[0054] Example 2 1 to 5 and 7, this embodiment differs from the first embodiment in the following respect: if the filter element mechanism 200 is damaged, it is necessary to remove the filter element mechanism 200. However, if a new filter element mechanism 200 for replacement is not available, liquid may leak from the through-hole 101a-1 corresponding to the removed filter element mechanism 200. This filter further comprises a self-closing mechanism 500 having a transition pipe 501 provided on the partition plate 101a, positioned corresponding to the through hole 101a-1, with a through hole 501a opened in its side wall and an upper open port 501b opened at one end near the through hole 101a-1, a reset part 502 provided inside the transition pipe 501, and a closing block 503 connected to the reset part 502, and when the positioning member 302 and the locking part 402 engage with each other, the positioning member 302 can disengage the closing block 503 from the upper open port 501b, and when the positioning member 302 and the locking part 402 separate, the reset part 502 can push the closing block 503 to close the upper open port 501b.

[0055] The reset part 502 comprises an internal tube 502a fixed inside the transition tube 501, a return spring 502b arranged inside the internal tube 502a, and a push column 502c abutting against the return spring 502b, and the closing block 503 is connected to the push column 502c and is slidably connected to the transition tube 501 by a slider and sliding groove structure.

[0056] The liquid that enters the discharge chamber 101c from the through hole 101a-1 first enters the inside of the transfer pipe 501 from the upper open port 501b, and the liquid that enters the inside of the transfer pipe 501 can enter the inside of the discharge chamber 101c through the through port 501a.

[0057] When the filter element mechanism 200 is not installed, the closing block 503 is biased by the return spring 502b to close the upper open port 501b, and when the filter element mechanism 200 is installed, the positioning member 302 moves in the first direction to press the closing block 503, which causes the closing block 503 to drive the push column 502c to press the return spring 502b, and the closing block 503 separates from the upper open port 501b.

[0058] When the filter element mechanism 200 is removed, the positioning member 302 moves in the second direction and no longer presses against the closing block 503. At this time, the return spring 502b drives the closing block 503 to reset through the push rod 502c. The closing block 503 closes the upper opening 501b and the through-hole 101a-1, thereby closing the corresponding through-hole 101a-1 after the filter element mechanism 200 is removed, thereby avoiding the problem of the liquid inside the filtering chamber 101b leaking into the discharge chamber 101c without being filtered.

[0059] To improve stability, a hole groove corresponding to the inner sliding groove of the transition pipe 501 is opened on the inside of the through hole 101a-1, and when biased by the return spring 502b, the closing block 503 can enter the inside of the through hole 101a-1 and close the through hole 101a-1.

[0060] Specifically, an auxiliary positioning member 101e is further provided inside the container body 101, and the auxiliary positioning member 101e includes an auxiliary plate 101e-1 fixed to the inside of the container body 101, a through hole 101e-2 opened in the auxiliary plate 101e-1, a guide tube 101e-3 fixed to the auxiliary plate 101e-1, and a position limiting block 101e-4 connected to the inside of the guide tube 101e-3, and a guide disc 202a is provided on the stable end 202, a coaxial post 202b is provided on the guide disc 202a, a rotatable position limiting disc 202c is provided on the outside of the coaxial post 202b, and the position limiting block 101e-4 can engage with the position limiting disc 202c.

[0061] The purpose of the auxiliary positioning member 101e is to prevent the filter element mechanism 200 from accidentally detaching. The auxiliary positioning member 101e is provided with an auxiliary plate 101e-1 fixed to the inside of the container body 101, a through hole 101e-2 passing through the auxiliary plate 101e-1, a guide tube 101e-3 fixed to the side of the auxiliary plate 101e-1 closer to the through hole 101a-1, a side groove 202a-1 for allowing the position limiting block 101e-4 to pass through, a U-shaped wheel 202b-1 provided on the outside of the coaxial post 202b, a position limiting disk 202c rotatably fitted around the outside of the U-shaped wheel 202b-1, a limiting groove 202c-2 opened in the side wall of the position limiting disk 202c, and a passage opening 202c-1 opened in the position limiting disk 202c.

[0062] When connecting the filter element mechanism 200, the entire filter element mechanism 200 passes through the through hole 101e-2, and when the positioning mechanism enters the inside of the connecting part 401, the position limiting disk 202c enters the inside of the guide tube 101e-3, and the diameter of the position limiting disk 202c matches the inner diameter of the guide tube 101e-3. After entering the inside of the guide tube 101e-3, the position limiting disk 202c can act as a guide for the entire filter element mechanism 200, so that the positioning member 302 can enter the inside of the connecting part 401 in a stable state.

[0063] When the position limiting disc 202c moves in a first direction inside the guide tube 101e-3, the position limiting block 101e-4 can pass through the guide disc 202a from the side groove 202a-1, and when the positioning member 302 and the locking part 402 engage, the position limiting block 101e-4 reaches the limiting groove 202c-2 from the passage opening 202c-1. At this time, by rotating the position limiting disc 202c, the position limiting block 101e-4 can reach the inside of the limiting groove 202c-2, and at this time, the filter element mechanism 200 can be restricted from moving, thereby avoiding the problem of accidental detachment due to malfunction of the filter element mechanism 200.

[0064] The other structures are the same as those in the first embodiment.

[0065] During the operation, when the filter element mechanism 200 is removed, the positioning member 302 moves in the second direction and no longer presses against the closing block 503. At this time, the return spring 502b drives the closing block 503 to reset through the pushing rod 502c. The closing block 503 closes the upper opening 501b and the through-hole 101a-1, thereby closing the corresponding through-hole 101a-1 after the filter element mechanism 200 is removed. This avoids the problem of the liquid inside the filtering chamber 101b leaking into the discharge chamber 101c without being filtered.

[0066] Example 3 1 to 8, this embodiment differs from the above-described embodiments in that, in order to prevent rotation of the filter element mechanism 200 and improve the stability of the filter element mechanism 200, the present filter further includes an anti-rotation mechanism 600 having an outer ring 601 provided on the outside of the communication head 301, an elastic shaft 602 provided on the side wall of the outer ring 601, and an engagement piece 603 slidably provided on the elastic shaft 602. When the positioning member 302 and the locking part 402 engage with each other, the engagement piece 603 can engage with the elastic member 402a. The engagement between the engagement piece 603 and the elastic member 402a prevents rotation of the filter element mechanism 200 and also prevents instability of the filter element mechanism 200 due to such rotation.

[0067] Specifically, the elastic member 402a comprises a lateral post 402a-1 slidably mounted on the connecting sheet 401a, and a first spring 402a-2 fitted to the outside of the lateral post 402a-1 and abutting against the blocking block 402b, wherein the lateral post 402a-1 penetrates the connecting sheet 401a, the blocking block 402b is located at one end of the inside of the connecting sheet 401a, and the first spring 402a-2 is used to apply a pressing force to the blocking block 402b, and one end of the lateral post 402a-1 away from the blocking block 402b extends to the outside of the connecting sheet 401a. Therefore, when the positioning member 302 and the locking part 402 engage with each other, the engagement piece 603 engages with the outside of the lateral post 402a-1, thereby preventing rotation of the filter element mechanism 200.

[0068] The elastic shaft 602 comprises an outer shaft body 602a fixed to the outer ring 601, a detachment prevention piece 602b fitted to the outer shaft body 602a, and a second spring 602c fitted to the outside of the outer shaft body 602a and abutting against the detachment prevention piece 602b. The engagement piece 603 is slidably fitted to the outside of the outer shaft so that the engagement piece 603 cannot rotate outside the outer shaft body 602a. This can be achieved by providing a groove in the outer shaft body 602a and a guide protrusion on the inside of the engagement piece 603.

[0069] In its natural state, the second spring 602c pushes the engagement piece 603 up toward the center of the connecting sheet 401a, and the connecting sheet 401a has a chamfered surface 401a-1. When the positioning member 302 moves in the first direction, the end of the engagement piece 603 abuts against the chamfered surface 401a-1, and the engagement piece 603 moves in a direction away from the center of the connecting sheet 401a, thereby compressing the second spring 602c and deforming the second spring 602c.

[0070] At the same time, an alignment groove is provided on the chamfered surface 401a-1 at a position corresponding to the lateral post 402a-1, with one end of the alignment groove being a closed end N1 close to the lateral post 402a-1 and the other end being an enlarged end N2 away from the lateral post 402a-1. The width of the alignment groove gradually decreases from the enlarged end N2 to the closed end N1, allowing the engagement piece 603 to be more accurately aligned with the lateral post 402a-1 through the guide of the alignment groove.

[0071] The other structures are the same as those in the second embodiment.

[0072] During operation, when the positioning member 302 and the locking part 402 engage, the engagement piece 603 engages with the outside of the lateral post 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 engagement piece 603 abuts against the chamfered surface 401a-1, and the engagement piece 603 moves in a direction away from the center of the connecting seat 401a; and the engagement piece 603 can be more accurately aligned with the lateral post 402a-1 by the guide of the alignment groove.

[0073] Example 4 Referring to FIG. 9, the difference between this embodiment and the above embodiment is as follows: the present invention further proposes a filtration system equipped with the powder pre-coated filter in the above embodiment, the system includes a dissolving box 1000 connected to a liquid inlet 102 and having a membrane pump 1001 installed between the dissolving box 1000 and the liquid inlet 102, the dissolving box 1000 contains a mixed suspension containing particulate impurities and dissolved iron impurities discharged from an air-cooled condenser, and the mixed suspension is transported to the inside of the filter via the membrane pump 1001 for filtration.

[0074] The system further comprises an overflow box 2000 connected to the overflow port 104, so that when the liquid level inside the filter becomes too high, the liquid will enter the inside of the overflow box 2000 through the overflow port 104.

[0075] To avoid the problem that the overflow pipe 3000 of the overflow box 2000 is located much lower than the powder precoat filter, which can cause a siphon phenomenon, turbulence inside the powder precoat filter, and unstable liquid flow, the present system further includes an overflow pipe 3000 connected to the overflow box 2000 and located at a height equal to or higher than the container body 101.

[0076] The other structures are the same as those in the third embodiment.

[0077] During operation, by raising the height of the overflow pipe 3000, the overflow box 2000 and the overflow pipe 3000 can reach a height above the liquid level in the container body 101, thereby avoiding the problem of water constantly flowing into the overflow box 2000 due to siphoning, causing turbulence inside the powder pre-coated filter. Furthermore, by opening an exhaust hole 3001 at the top of the overflow pipe 3000, the siphoning caused by the overflow pipe 3000 itself can be avoided, and the overflow box 2000 can be kept at full capacity.
