Description

Filtering system
Technical Field
The invention relates to the technical field of filtration, in particular to a filtration system.
Background
US patent 7338599 discloses a filtration system 10 comprising a filter 13, a manifold 12, a bracket 11, and a mounting mechanism 16, the bracket 11 supporting the filter 13 such that the filter 13 is engaged with or disengaged from the manifold 12, the mounting mechanism 16 being a pivotable lever arrangement associated with the manifold 12 and the bracket 11, the pivotable lever arrangement comprising a lever 51, a pivot pin 53 connected between the manifold 12 and the lever 51, and a pin and slot assembly connected between the lever 51 and the bracket 11.
The lever 51 is arranged for pivotal movement about the pivot pin 53 between a first position in which the filter 13 is spaced from the manifold 12 and a second position in which the tube of the filter 13 is engaged with the tube of the manifold 12, the pin 58 of the pin and slot assembly being arranged to slide between a first position in the slot 57 and a second position in the slot, the filter 13 being engaged with or disengaged from the manifold 12 as the lever 51 is pivotally moved about the pivot pin 53 between the first and second positions and the pin 58 slides between the first and second positions.
When the filter system 10 is used and the filter 13 needs to be replaced, the operating lever 51 is used to make the operating lever perform pivoting motion around the pivot pin 53, the pin 58 slides in the groove 57, the lever 51 moves towards the first position, the bracket 11 drives the filter 13 to move downwards, and when the operating lever 51 reaches the first position, the filter 13 is separated from the manifold 12, and the filter 13 reaching the maximum service life is taken out; a new filter 13 is reinstalled and lever 51 is operated to pivot about pivot pin 53, pin 58 slides in slot 57, lever 51 moves toward the second position, and bracket 11 moves filter 13 upward, and filter 13 engages manifold 12 when lever 51 reaches the second position.
In this filter system 10, in order to facilitate the unhindered sliding of the pin 58 within the slot 57, i.e. the handling of the rod 51, the edges of the slot 57 are provided with a smooth arc, and the cylindrical pin 58 slides along the arc-shaped edges of the slot 57, bringing about the upward or downward movement of the bracket 11 and the filter 13, and finally the engagement or disengagement of the filter 13 with the manifold 12.
When the rod 51 is in the second position, i.e. when the filter 13 is engaged with the manifold 12, a certain squeezing action is created between the joint of the filter 13 and the tube of the manifold 12 and a sealed connection is formed, ensuring that no leakage occurs during the filtration process. However, when the filter 13 and the manifold 12 are in the engaged position during the filtration process, the pin 58 is not firmly locked in the groove 57 because the arc-shaped edge of the groove 57 is smooth, and when the rod 51 is inadvertently touched, the pin 58 slides in the groove 57 in the opposite direction, and the rod 51 is pivotally moved from the second position to the first position, and as a result, the bracket 11 is moved downward a certain distance along with the filter 13, so that the squeezing action between the joint of the filter 13 and the pipe of the manifold 12 is lost, the sealing performance is greatly reduced, and serious fluid leakage occurs.
In addition, when the filter system 10 is used for installing or removing the filter 13, the operating rod 51 is pivoted to move the bracket 11 and the filter 13 upwards or downwards simultaneously, so that the joint of the filter 13 is connected with or separated from the pipe fitting of the manifold 12, and because the bracket 11 and the filter 13 are required to be moved simultaneously during the installation and removal processes, the operating rod 51 needs great effort for an operator to push the rod 51, namely, the installation and removal operations of the filter system 10 are not labor-saving.
Therefore, there is a need for an improved filter system mounting mechanism to ensure effective control of the mounting state of the filter system, and to prevent uncontrolled movement of the rod when the filter system is in the mounting position, which would cause the bracket to move the filter in a direction away from the manifold, thereby avoiding the problem of loss of sealing and squeezing between the filter joint and the manifold tube, which would cause a loss of sealing performance. In addition, it is desirable to improve the manner in which the filter system is installed and removed so that the filter installation and removal operations are less labor intensive and simplified.

Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
As shown in fig. 1, the filter 1 includes a barrel and a filter element fixed inside the barrel, wherein 3 connectors, a first connector 10, a second connector 11 and a third connector 12 are arranged on an end cover at the top of the barrel and are used as a fluid inlet, a fluid outlet and a gas outlet.
The manifold block 2 as shown in fig. 2a and 2b comprises a fixing portion 20 at the inner side, a manifold plate 21 horizontally extending from the inner side to the outer side, and slide grooves 22 at both sides of the manifold block 2, the slide grooves 22 comprising a horizontal groove section 220 and a vertical groove section 221.
In the present embodiment, the vertical groove section 221 and the horizontal groove section 220 of the sliding groove 22 are separately arranged, and the axial height of the bottom of the vertical groove section 221 is not less than the axial height of the lower edge of the horizontal groove section 220, that is, the bottom of the vertical groove section 221 is flush with the lower edge of the horizontal groove section 220 or the bottom of the vertical groove section 221 is located above the lower edge of the horizontal groove section 220 in the axial direction.
In fact, the vertical groove section 221 and the horizontal groove section 220 of the sliding groove 22 may also form an integrated L-shape, in which case the bottom of the vertical groove section 221 is flush with the lower edge of the horizontal groove section 220, and when the vertical groove section 221 and the horizontal groove section 220 are integrated L-shape, the horizontal distance between the first pin member 5 and the second pin member 6 is greater than the length of the horizontal groove section 220. The positions of the first pin member 5 and the second pin member 6 will be explained below.
The fixing portion 20 is used to fix the manifold block 2 in the pipe, and the manifold plate 21 is provided with 3 openings 210 for fixing the pipe members 8 (fig. 6-8), the positions of the pipe members 8 corresponding to the positions of the 3 joints 10,11 and 12 at the top of the filter 1, so that a sealed connection can be formed therebetween.
The manifold base 2 is fixed to the pipe by the fixing portion 20, and a side of the manifold base 2 close to the fixing portion 20 is defined as an inner side, and a side opposite to the fixing portion 20 is defined as an outer side.
The locking position of the second pin member 6 is formed on the inner side of the horizontal groove section 220, which refers to the position of the second pin member 6 when the pipe 8 of the manifold block 2 and the joints 10,11 and 12 of the filter 1 are sealingly connected (fig. 8), and the inner side of the locking position is located in the inner region of the extension line of the outer side groove wall of the vertical groove section 221, while the outer side of the horizontal groove section 220 is located in the outer region of the extension line of the outer side groove wall of the vertical groove section 221, which ensures that the moment to which the second pin member 6 in the locking position is subjected is always small and thus cannot slide along the horizontal groove section 220 towards the outer side.
To ensure that the second pin member 6 in the locking position does not slide along the horizontal groove section 220 to the outside, further, when the second pin member 6 is in the locking position, when the center of the second pin member 6 is located at the right side of the central axis of the vertical groove section 221, the lower edge of the horizontal groove section 220 has a first section and a second section, the second section is the locking position of the second pin member 6, the locking portion 23 is formed at the junction of the first section and the second section, for example, the locking portion 23 may be a protrusion protruding from the lower edge of the horizontal groove section 220, and the horizontal distance between the locking portion 23 and the inside of the horizontal groove section 220 is smaller than the outer diameter of the second pin member 6. Therefore, the locking portion 23 can contact and abut against the outer surface of the second pin member 6 reaching the second section (locking position) region, and prevent the second pin member 6 from sliding outward along the horizontal groove section 220.
Further, it is also possible to provide the second section with a recess 24 having an axial height smaller than that of the first section, and to provide the second pin member 6 in the second section (locking position) having an axial height lower than that of the first section when the pipe member 8 of the manifold block 2 and the joints 10,11 and 12 of the filter 1 are sealingly connected, so as to be restrained in the recess 24 corresponding to the second section and not to slide in the outer direction.
In addition, a restricting portion 25 is provided on one of the sides of the manifold table 2, protruding axially outward of the manifold plate 21, for controlling the maximum stroke of counterclockwise rotation of the operating rod 4.
The bracket 3 shown in fig. 3 has vertical slots 30 on both sides, and pin holes 31 and positioning holes 32 at the bottom for positioning the filter 1 are provided outside the vertical slots 30 and at an axial height higher than the vertical slots 30.
It should be noted that the number of the vertical slots 30 may be 1, that is, the vertical slots 30 are only provided on one side of the bracket 3.
As shown in fig. 4, the operating rod 4 has two sides of a transmission part 40, a closed end of a handle 41, two ends of the handle 41 are transitionally connected with the transmission part 40 through a connecting part 42, and two ends of the transmission part 40 are provided with a first pin hole 400 and a second pin hole 401 for inserting the first pin member 5 and the second pin member 6 respectively.
As shown in fig. 5, the manifold table 2, the bracket 3 and the operation lever 4 are assembled, one end of the transmission part 40 of the operation lever 4 is connected to the bracket 3 and the manifold table 2 by a first pin member 5 passing through the vertical slot section 221 of the slide slot 22, and the other end is connected to the manifold table 2 by a second pin member 6 passing through the horizontal slot section 220 of the slide slot 22, i.e., the first pin member 5 passes through the vertical slot section 221, the first pin hole 400 of the transmission part 40 and the pin hole 31 of the bracket 3 in sequence to movably associate the manifold table 2, one end of the operation lever 4 and the bracket 3, and the second pin member 6 passes through the horizontal slot section 220 and the second pin hole 401 of the transmission part 40 in sequence to movably associate the manifold table 2 and the other end of the operation lever 4.
Since the axial height of the bottom of the vertical groove section 221 is not less than the axial height of the lower edge of the horizontal groove section 220, i.e. the bottom of the vertical groove section 221 is flush with the lower edge of the horizontal groove section 220 or the bottom of the vertical groove section 221 is located axially above the lower edge of the horizontal groove section 220, it enables the axial height of the first pin member 5 passing through the vertical groove section 221 to be always greater than or equal to the axial height of the second pin member 6 passing through the horizontal groove section 220, which can reduce the rotation amplitude of the operating rod 4 during installation and disassembly, i.e. the operating rod 4 only needs to complete a small amplitude of rotation, and thus the sealing connection or disconnection between the joints 10,11 and 12 of the filter 1 and the pipe 8 of the manifold table 2 can be realized.
In addition, in order to improve structural stability, a reinforcing bar (not shown) is connected between the first pin member 5 and the second pin member 6, and the extending direction of the reinforcing bar is parallel to the extending direction of the transmission portion 40.
The bracket 3 and the manifold table 2 are further connected by a third pin member 7 passing through the vertical slot 30, in this embodiment, two vertical slots 30 are respectively arranged at two sides of the bracket 3, the third pin member 7 is an integrated link rod passing through the manifold table 2, and two ends of the link rod are connected to the vertical slots 30 at two sides of the bracket 3. Alternatively, the third pin member 7 may be two separate pin members, and the two separate pin members may be connected to the manifold block 2 by passing through the vertical grooves 30 on both sides of the bracket 3.
As shown in fig. 6-8, in the present embodiment, the manifold table 2 is fixed in the pipeline by the fixing portion 20, during the installation of the filter 1, the filter 1 is fixed on the bracket 3 by the positioning hole 32 at the bottom of the bracket 3, the ports 10,11 and 12 at the top of the filter 1 are aligned with the 3 pipe fittings 8 on the manifold table 2, a force in an inclined downward direction is applied to the handle 41 of the operating rod 4, during the rotation of the operating rod 4 around the first pin member 5, the first pin member 5 moves vertically upward in the vertical groove section 221 of the chute 22, the second member 6 moves horizontally in the horizontal groove section 220 of the chute 22, and the vertical groove 30 of the bracket 3 moves vertically upward along the third pin member 7, so that the bracket 3 and the filter 1 move vertically upward, and the pipe fittings 8 of the manifold table 2 and the ports 10,11 and 12 of the filter 1 are connected in a sealing manner.
Wherein the maximum difference between the axial height of the first pin member 5 and the axial height of the second pin member 6 is equal to the maximum sliding travel of the third pin member 7 in the vertical slot 30 of the bracket 3, which ensures that when the first pin member 5 reaches the end of the vertical slot section 221, the third pin member 7 also reaches the end of the vertical slot 30, which can improve the stability of the filter 1 in the installed state and avoid the filter 1 from shaking axially.
When a force in an obliquely upward direction is applied to the operating lever 4, the first pin member 5 moves vertically downward in the vertical groove section 221 of the slide groove 22, the second member 6 moves horizontally in the horizontal groove section 220 of the slide groove 22, the vertical groove 30 of the bracket 3 moves vertically downward along the third pin member 7, the bracket 3 and the filter 1 are driven to move vertically downward, and the pipe 8 on the manifold block 2 is completely separated from the joints 10,11 and 12 of the filter 1, so that the filter 1 can be replaced.
In other embodiments, the bracket 3 can be fixed in the pipeline, the filter 1 is fixed on the bracket 3 through the positioning hole 32 at the bottom of the bracket 3 in the installation process, i.e. the bracket 3 and the filter 1 are fixed in the whole filtering system, the installation process, the interfaces 10,11 and 12 at the top of the filter 1 are aligned with the 3 pipe fittings 8 on the manifold table 2, the handle 41 of the operating rod 4 is applied with a force in an inclined downward direction, the vertical groove section 221 of the chute 22 of the manifold table 2 moves vertically downward along the first pin member 5 under the force of the operating rod 4 in the rotation process of the operating rod 4 around the first pin member 5, the second pin member 6 moves horizontally in the horizontal groove section 220 of the chute 22, the third pin member 7 moves vertically downward in the vertical groove 30, and drives the manifold table 2 to move vertically downward, so that the pipe fittings 8 of the manifold table 2 and the joints 10 of the filter 1, 11 and 12 are sealingly connected.
During the disassembly, a force in an obliquely upward direction is applied to the handle 41 of the operating lever 4, and during the rotation of the operating lever 4 about the first pin member 5, under the force of the operating lever 4, the vertical groove section 221 of the chute 22 of the manifold table 2 moves vertically upward along the first pin member 5, the second pin member 6 moves horizontally in the horizontal groove section 220 of the chute 22, and the third pin member 7 moves vertically upward in the vertical groove 30, which brings the manifold table 2 into vertical upward movement, so that the pipe members 8 of the manifold table 2 are disengaged from the joints 10,11, and 12 of the filter 1.
That is, in the filtering system provided by the present invention, the manifold table 2 may be fixed, or the bracket 3 may be fixed, and during the mounting and dismounting of the filter 1, the operating rod 4 rotates around the first pin member 5, so that the first pin member 5 and the vertical groove section 221 of the chute 22 perform relative movement in the vertical direction, the second pin member 6 performs horizontal movement in the horizontal groove section 220 of the chute 22, the third pin member 7 and the vertical groove 30 perform relative movement in the vertical direction, and further, the manifold table 2 and the bracket 3 and the filter 1 perform relative movement in the vertical direction, so that the pipe 8 of the manifold table 2 and the joints 10,11 and 12 of the filter 1 are separated or sealed.
After the filter 1 and the manifold table 2 are connected in a sealing manner, the first pin member 5 and the second pin member 6 connected to the two ends of the transmission part 40 of the operating rod 4 are respectively subjected to extrusion force which is generated by the edge of the pin hole 31 of the bracket 3 and the horizontal groove section 220 of the sliding groove 22 of the manifold table 2 and has a direction parallel to the axial direction of the filter 1 and the manifold table 2, so that the second pin member 6 is not easy to slide in the horizontal groove section 220 towards the outer side direction, the operating rod 4 is not easy to rotate anticlockwise, and the risk of failure of the sealing connection between the joints 10,11 and 12 of the filter 1 and the pipe 8 of the manifold table 2 is greatly reduced. And, since the axial height of the bottom of the vertical groove section 221 is not less than the axial height of the lower edge of the horizontal groove section 220, it can reduce the rotation amplitude of the operation rod 4 during the mounting and dismounting process, and therefore, the operation is more labor-saving.
While the preferred embodiments of the present invention have been illustrated and described in detail, it should be understood that various changes and modifications of the invention can be effected therein by those skilled in the art after reading the above teachings of the invention. Such equivalents are intended to fall within the scope of the claims appended hereto.
