Description
Technical Field
The utility model belongs to the technical field of B01D25/12 pressure filter, in particular to filter press of filter plate and applied this filter plate that machinery is squeezed and air current drying coordinated action.
Background
The filter press is a machine for solid-liquid separation, and is often used for sludge-water separation. When the device is used, firstly, the water-containing sludge is pumped into the filter plates to form a filter pressing cavity, the water-containing sludge is fed and pressed by the pressure of the sludge feeding pump, and then the force is applied to the filter pressing cavity through the high-pressure oil cylinder to perform secondary pressing. In the prior art, sometimes a high-pressure oil cylinder is not used for squeezing, high-pressure gas is directly used for acting on a filter cake, and high-pressure airflow has the effects of both squeezing and drying. However, the high-pressure oil cylinder pressing is a pressing mode with stable acting force and has incomparable effect compared with high-pressure gas pressing. Chinese patent document CN 107670353A discloses a multi-chamber sludge high-dryness dewatering device, which adopts the coordination action of mechanical pressing and air flow drying, wherein the mechanical pressing mode comprises two modes of feeding pressing and high-pressure oil cylinder pressing. This application is the improvement to this scheme to further improve sludge drying efficiency, make things convenient for the filter plate to drop from between the filter plate simultaneously.
Disclosure of Invention
An object of the utility model is to overcome prior art's not enough, provide a machinery and squeeze and the filter press of this filter plate with the filter plate of air current drying concerted action to improve sludge drying efficiency, make things convenient for the filter cake to drop from between the filter plate simultaneously.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
mechanical press and the dry concerted action's of air current filter plate, one side of filter plate is the bulge, and the opposite side of filter plate is the depressed part, realizes the sealing connection of adjacent filter plate and forms the filter-pressing cavity between bulge and depressed part through grafting of bulge and depressed part between the adjacent filter plate, and the both sides of filter-pressing cavity are the filter membrane, and the filter plate is equipped with air duct and filter membrane intercommunication, the tip of bulge is the inclined plane, and the bottom of depressed part is the inclined plane, makes the filter cake that forms in the filter-pressing cavity be the tilt state.
As a modification, the end of the projection is provided with a rib.
As an improvement, the bottom of the concave part is provided with a convex rib.
As a further improvement, the filter cake formed in the filter pressing chamber is in an inclined state with the top facing outwards.
The filter press comprises a power mechanism and a filter plate mechanism, wherein the filter plate mechanism comprises a head plate, a tail plate and a middle filter plate, and the middle filter plate is the filter plate.
The utility model has the advantages that: the end part of the protruding part and the bottom of the recessed part are changed into inclined planes, so that when the second-stage pressing of the high-pressure oil cylinder is carried out, the filter cake can be twisted in opposite directions in an inclined mode, the sludge part originally in the filter cake is exposed to the surface, and particularly after the convex ribs are arranged, the effect brought by the acting force is more obvious. Because the existence of bead, the mud of bead root is inseparable relatively when mechanical oppression, and when follow-up high-pressure gas that carries on blown, the mud of bead root can separate with the filter membrane more easily to make filter cake and filter membrane whole separation fast, be favorable to the rapid draing of filter cake, also can not drop because the adhesion of filter cake and filter membrane influences the automation of later stage filter cake. On the other hand, because the bead card is in the filter cake, when high-pressure gas blows, high-pressure gas can direct contact filter cake inside, is favorable to the rapid draing of filter cake. After the sludge is subjected to filter pressing, the adjacent filter plates are separated, the filter cake is not adhered to the filter membrane, and the inclined filter cake falls down naturally.

In the figure: 10. a projection; 20. a recessed portion; 30. a filter pressing chamber; 40. filtering the membrane; 50. an air duct; 60. a rib; 70. a head plate; 80. a tail plate; 90. and (4) an intermediate filter plate.
Detailed Description
Example 1
As shown in fig. 1, the filter press of the present invention comprises a power mechanism and a filter plate mechanism, wherein the filter plate mechanism comprises a head plate 70, a tail plate 80 and a middle filter plate 90, the middle filter plate 90 is the filter plate of the coordination effect of mechanical pressing and air flow drying, and the others are the prior art.
Mechanical press with air current drying concerted action's filter plate, one side of filter plate is bulge 10, the opposite side of filter plate is depressed part 20, realize the sealing connection of adjacent filter plate and form filter-pressing cavity 30, the state after the adjacent filter plate that fig. 2 shows is pegged graft between bulge 10 and depressed part 20 through the grafting of bulge 10 with depressed part 20 between the adjacent filter plate. The end of the convex part 10 is an inclined plane, the inclined angle of the inclined plane is about 15 degrees, and the excessive inclined angle easily causes the excessive thickness of the filter cake to influence the dehydration efficiency. The inclined plane is provided with a convex edge 60, the bottom of the depressed part 20 is an inclined plane, the inclined angle of the inclined plane is about 15 degrees, and the inclined plane is provided with the convex edge 60, so that a filter cake formed in the filter pressing chamber 30 is in an inclined state with the top facing outwards. The two sides of the filter pressing chamber 30 are both filter membranes 40, and the filter membranes 40 wrap the convex edges 60 at the same time. The filter plate is provided with an air passage 50 which is communicated with the filter membrane 40. Because of the stopping of bead 60, when the filter cake was oppressed by machinery, the filter cake of bead 60 root one side was oppressed not strictly relatively, and after the air duct 50 let in high-pressure gas, filter membrane 40 at first separated with the filter cake here, then separated filter membrane 40 and filter cake comprehensively, made the probability greatly reduced that filter cake and filter membrane 40 take place the adhesion, after adjacent filter plate separation, the filter cake can drop automatically promptly.
