All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 9, the invention provides a filter press for solid-liquid separation, the filter press comprises a filter press body and a plurality of filter plates 1 movably connected to the filter press body, a filter screen is arranged between adjacent filter plates 1, each filter plate 1 comprises a base plate 2, the surface of each filter plate is provided with a groove, a filter area 3 is arranged in each groove, an edge area is arranged at the outer side of each filter area 3, and the edge areas are arranged around the filter areas 3; the additional plate 4, the additional plate 4 is detachably connected with the base plate 2 (the connection mode can be selected to be fixedly connected through pins); wherein, the central area of the additional plate 4 is provided with a bonding block 5, the shape of the bonding block 5 is matched with the shape of the groove, and when the additional plate 4 is connected with the base plate 2, the bonding block 5 is clamped into the groove and fully bonded with the inner wall of the groove; the attaching block 5 can be separated from the groove and guide filter residues attached to the surface of the attaching block to fall off through separation action.
According to the invention, the adhesion probability of filter residues can be reduced through the matching of the bonding block 5 and the groove, specifically, the additional plate 4 is directly fixed on the base plate 2, at the moment, the bonding block 5 is clamped into the groove and is fully bonded with the inner wall of the groove, after the filtration is finished, if part of filter residues are adhered to the bonding block 5, the bonding block 5 can be directly guided to be separated from the groove, and the filter residues adhered to the surface of the bonding block 5 can be guided to fall after the bonding block 5 is separated, so that the filter residues can be cleaned with higher efficiency.
The motion state of the lamination block 5 can refer to fig. 2 and 3, wherein the lamination block 5 in fig. 3 only shows the motion state, the filtering holes on the lamination block are not shown, and the lamination block 5 can be made of rubber or silica gel.
Since the attaching block 5 is easy to slide after being clamped into the groove, in some embodiments, the filtering area 3 is disposed at the bottom area of the groove, and the edge area is disposed at the inner side wall area of the groove;
The surface of the additional plate 4 is provided with a frame hole, and the attaching block 5 is fixedly arranged in the frame hole; the laminating piece 5 includes the interior subsides piece 6 that sets up with recess assorted, and the outside of interior subsides piece 6 is equipped with frame hole inside wall fixed connection's separation ring piece 7, and the surface of interior subsides piece 6 is equipped with a plurality of tie points 8 that are used for carrying out spacing to interior subsides piece 6, and interior subsides piece 6 passes through tie point 8 and recess inner wall swing joint.
When the attaching block 5 is clamped into the groove, the surface of the inner attaching block 6 is attached to the groove in a matching way, and meanwhile, the position of the inner attaching block 6 cannot be dislocated through the connecting points 8, the connecting points 8 can be magnets or bayonet locks (namely, pin holes corresponding to the bayonet locks are arranged in the groove, and the bayonet locks and the pin holes can be connected through interference fit), the number of the connecting points 8 can be 4-10, preferably 8, and in the invention, the connecting points 8 are preferably magnets.
The mode that the attaching block 5 is separated from the groove can be selected to be pulled out by a manual or external auxiliary device, but the mode that the manual or external auxiliary device is pulled out is low in efficiency and is not suitable for carrying out the separation operation on a large number of attaching blocks 5, so that in some embodiments, a plurality of pushing strips 9 are rotationally arranged on the surface of one side of the inner attaching block 6, which is close to the substrate 2, and all pushing strips 9 are arranged along the edge of the groove;
With the center of the groove as a reference, an inflation cavity 10 surrounding the groove is formed in the substrate 2, a plurality of alignment holes are formed in the inner side wall of the inflation cavity 10, push rods 11 are movably connected in each alignment hole, the end parts of each push rod 11 are respectively abutted to the surface of each push rod 9, a push ring 12 is slidably connected in the inflation cavity 10, the shape of the push ring 12 is matched with the inflation cavity 10 and can reciprocate along the inner wall of the inflation cavity 10, and the push ring 12 and one end of each push rod 11 far away from the push rod 9 are fixedly connected.
The inner sticking block 6 comprises a filter hole section 13 with the shape matched with the filter area 3, a bulge section 14 fixedly connected with the separation ring block 7 and matched with the shape of the edge area is arranged on the outer side of the filter hole section 13, and an expansion cavity 15 is arranged in the bulge section 14;
The surface of one side of the additional plate 4, which is close to the base plate 2, is provided with a shaping air passage block 16 communicated with the expansion cavity 15, and the inner side wall of the shaping air passage block 16 is provided with a flexible belt 17 fixedly connected with all pushing strips 9 (the flexible belt 17 is made of rubber material, and the surface of the base plate 2 is also provided with a groove for accommodating the shaping air passage block 16 and the flexible belt 17).
In the invention, the two additional plates 4 are arranged on two sides of the base plate 2, so the two pushing rings 12 are also arranged, and the edge of each pushing ring 12 can be provided with a rubber sheet (one end of the rubber sheet is in sealing connection with the pushing ring 12, and the other end of the rubber sheet is connected with the inner wall of the inflating chamber 10), so that the sealing performance between the pushing ring 12 and the inflating chamber 10 is higher, and when the air is introduced into the inflating chamber 10, the air enters the space between the two pushing rings 12.
If the fitting block 5 in the groove needs to be disengaged, the air is directly inflated into the inflation chamber 10, then the pressure is increased along with the increase of the air in the inflation chamber 10, and then the air is pushed to move along the inner wall of the inflation chamber 10 towards the push rod 11 side, namely, the push ring 12 gradually pushes all the push rods 11 out of the inflation chamber 10.
Then, the pushed push rod 11 pushes the push rod 9 to deflect, the push rod 9 deflects by taking the flexible belt 17 as a rotation pivot, and meanwhile, one end of the push rod 9 away from the flexible belt 17 pushes the bulge section 14 to separate from the edge area, and along with the separation of the bulge section 14, the filter hole section 13 also separates from the filter area 3 until the bulge section 14 and the filter hole section 13 separate to the position shown in fig. 3.
If the bulge section 14 and the filter hole section 13 are required to be reset, the bulge section 14 and the filter hole section 13 are only required to be reset by discharging the gas in the inflation chamber 10 and manually pushing the bulge section 10.
In some embodiments, the central axis of the push rod 11 is perpendicular to the surface of the push bar 9 or is deflected towards the centre of the groove by a set angle (the set angle is preferably 15-45 degrees).
The deflection of the set angle towards the centre of the groove is to make the deflection angle of the push rod 11 larger, and the bulge section 14 and the filter hole section 13 are easier to disengage from the groove.
Because some filter residues have greater adhesiveness, and particularly the bulge section 14 is more likely to adhere to the filter residues, in some embodiments, the bulge section 14 has a plurality of mounting bars 18 on its surface, all of the mounting bars 18 being disposed along the inner side walls of the bulge section 14, and receiving areas being provided between adjacent mounting bars 18; when the expansion chamber 15 in the bulge section 14 is introduced with gas, the bulge section 14 expands and the distance between the guide receiving areas increases.
As the bulge section 14 and the filter hole section 13 separate from the edge zone and the filter zone 3, respectively, gas will also gradually enter the expansion chamber 15, and at this time, the bulge section 14 expands and the space guiding the accommodation zone increases, which means that the contact area between the filter residues and the mounting strip 18 decreases, so that the filter residues are more likely to fall off.
In some embodiments, the mounting bar 18 is a rectangular bar structure or a structure formed by a plurality of convex points arranged in a linear array or a structure with a semicircular longitudinal section. The mounting bar 18 is configured such that the contact area between the mounting bar 18 and the filter residue is small.
One end of the mounting strip 18 is flush with the surface of the side of the additional plate 4 away from the base plate 2, and the other end is at least in abutment with the surface of the filter hole section 13. The mounting bars 18 are dimensioned such that no filter residue is present at the connection between the bulge section 14 and the filter hole section 13.
In some embodiments, in order to implement the operation of inflating the bulge section 14, it is preferable that the sidewall of the base plate 2 is provided with an air guide block 19, the air guide block 19 is communicated with the inflating chamber 10, the air guide block 19 is provided with a plugging hole 20 for guiding air, and the additional plate 4 is provided with an insertion head 21 capable of being inserted into the plugging hole 20 to guide air into the shaping airway block 16.
The insertion head 21 may be composed of a straight block and a plug capable of being inserted into the insertion hole 20, wherein the plug and the insertion hole 20 may be in transition fit.
When introducing gas in the air guide block 19, the gas is introduced into the inflating chamber 10, and meanwhile, the gas is led into the insertion head 21 gradually through the inserting holes 20, and then the gas entering the insertion head 21 enters the shaping airway block 16 and the inflation cavity 15 between the insertion head 21, so that the inflation cavity 15 is inflated.
The diameter of the filter holes on the filter hole section 13 is larger than or equal to the diameter of the filter holes at the filter zone 3. This is so arranged so that the filter cake will not clog the filter holes on the filter hole section 13, while in some embodiments, a guide piece that can extend into the filter holes on the filter zone 3 may be arranged at the edge of the filter holes on the filter hole section 13 (the guide piece is used to prevent the filter cake from being stuck in the filter holes on the filter hole section 13), once the filter hole section 13 is separated from the groove, the filter holes on the filter hole section 13 will be stretched and expanded so that the filter cake in the filter holes on the filter hole section 13 is discharged.
When the filter plate 1 is used, the additional plate 4 is fixed on the base plate 2, the insertion head 21 is inserted into the insertion hole 20, the attaching block 5 is clamped into the groove and is fully attached to the inner wall of the groove, so that the filter plate 1 is spliced, filtering is performed according to the using mode of a plate-and-frame filter press in the prior art, after the filtering is finished, if part of filter residues are adhered to the attaching block 5, gas can be introduced into the gas guide block 19 through an external conduit and a ventilation device, and then the gas is introduced into the gas charging cavity 10.
As the gas in the inflation chamber 10 increases, the pressure increases, and then the gas pushes the pushing ring 12 to gradually push all the pushing rods 11 out of the inflation chamber 10 along the inner wall of the inflation chamber 10 toward the pushing rods 11.
Then, the pushed push rod 11 pushes the push rod 9 to deflect, the push rod 9 deflects by taking the flexible belt 17 as a rotation pivot, and meanwhile, one end of the push rod 9 away from the flexible belt 17 pushes the bulge section 14 to separate from the edge area, and along with the separation of the bulge section 14, the filter hole section 13 also separates from the filter area 3 until the bulge section 14 and the filter hole section 13 separate to the position shown in fig. 3.
When the gas is introduced into the inflating chamber 10, the inserting holes 20 can guide the gas to gradually enter the inserting head 21, and then the gas entering the inserting head 21 can enter the shaping airway block 16 and the inflating cavity 15, so that the inflating cavity 15 is inflated, the inflating section 14 is inflated to guide the interval of the accommodating area to be increased, which means that the contact area between the filter residues and the mounting strip 18 is reduced, and the filter residues are easier to fall off.
The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this application will occur to those skilled in the art, and are intended to be within the spirit and scope of the application.
