Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 5, the present embodiment discloses a novel plastic filter plate for a filter press, which comprises a main body 1, a liquid inlet hole 2, a boss 3, salient points 4, a liquid outlet hole 5, a handle 6, and a cloth holder 7.
The main part 1 has the circular plate body structure that the plastics material (specifically can adopt materials such as polymer polypropylene) was made, 1 center department in main part is equipped with through-hole structure's feed liquor hole 2, and after a plurality of filter plates transversely aligned the laminating installation, feed liquor hole 2 in every filter plate main part forms an inlet channel, and forms between the adjacent filter plate and hold chamber 8 (as shown in figure 3), and liquid is in this inlet channel through outside hydraulic equipment input, carries to each as main channel and holds in the chamber 8, finally fills up each and holds chamber 8.
The main part 1 is located the boss 3 that the 2 outsides in feed liquor hole are equipped with a plurality of centrosymmetry, 3 main effects of boss lie in can playing the supporting role between adjacent main part 1, when holding in the intracavity 8 when being in high-pressure state, can effectively reduce main part 1 and produce deformation, thereby influence the filter-pressing effect, in addition, boss 3 can also play moulding effect to the filter cake that obtains after the filter-pressing, make the filter cake form a plurality of groove structure, this helps promoting overall structure intensity, reduce the not fashioned phenomenon of filter cake.
It should be noted that, the central position of the boss 3 is provided with the communication hole 31, the communication hole 31 penetrates through the main body 1, therefore, when a plurality of main bodies 1 are tightly attached, the communication hole 31 can play a role of connecting adjacent containing cavities 8, when the containing cavity 8 at the front end position is sufficiently filled in the feeding process, the redundant concentrated solution can enter the next containing cavity 8 through the communication hole 31, which helps to increase the feeding speed, thereby affecting the working efficiency, and the communication hole 31 can also play a role of regulating, even if a plurality of tightly attached filter plates form a whole, the connection between the filter plates is tighter, in the filter pressing process, the pressure in each containing cavity 8 can be ensured to be kept consistent, therefore, the filter pressing effect at each position is kept consistent, and the filter pressing effect of each region can be even and efficient.
The peripheral edge parts 11 are arranged on the two side surfaces of the main body 1 and close to the outer side edges, the thickness of the peripheral edge parts 11 is not less than that of the bosses 3, so that the tightness of the edge regions between the adjacent filter plates after connection can be ensured, the peripheral edge parts 11 are provided with annular sealing flanges 12, the outer side surfaces of the annular sealing flanges 12 are of arc surface structures, as shown in figure 2, the sealing flanges 12 on the two sides of the same main body 1 are arranged in a staggered mode, and by combining figure 3, after the main bodies 1 are mutually attached, the outer side ends of the sealing flanges 12 on the two sides can be abutted against the side surfaces of the adjacent main bodies 1 in a staggered mode to form a sealing clamping structure, and after being squeezed and clamped by the sealing flanges 12 in different directions on the two sides, the filter cloth 9 can be deformed into an S-shaped structure and tightly pressed and attached between the two adjacent main bodies 1, so that the sealing effect between the adjacent main bodies 1 is greatly improved, and the overflow of filtrate from the gap is avoided, the problem of insufficient sealing performance between adjacent filter plates is solved.
As shown in fig. 2, a drain hole 5 is formed in the bottom of the main body 1, the drain hole 5 has a Y-shaped profile in longitudinal section, and the top thereof is open to both side surfaces of the main body 1. The drain holes 5 have the main function that in the filter pressing process, filtrate obtained by filtering through the filter cloth 9 can be discharged downwards in time, and the effect of solid-liquid separation is realized. It should be noted that, when the filter cloth 9 located near the top opening of the liquid discharge hole 5 is under high pressure, the top opening of the liquid discharge hole 5 is used as a pressure relief point, which may cause the filter cloth 9 to deform and be attached to the opening after being bent, thereby forming a filtering effect of the liquid discharge hole 5, which only satisfies the passing of filtrate, and the solids in the liquid are blocked in the accommodating cavity 8, and finally forming a filter cake with a low water content.
Still the equipartition has bump 4 that a plurality of intervals set up on main part 1 both sides face, combine shown in fig. 4 (in the picture bump 4 be for omitting the formula drawing method, and the actual bump 4 is evenly laid in the region except that feed liquor hole 2 and boss 3 on main part 1 both sides face), it needs to explain that, bump 4 highly be less than boss 3's height for bump 4 can not influence boss 3's support effect, main part 1 side top bump 4's density is greater than main part 1 side below bump 4's density, forms the passageway between the adjacent bump 4, and the filtrating can be followed this passageway and discharged to outage 5 departments downwards, and the dense distribution structure of loosing down can make full use of the space, promotes flowing back speed.
As shown in fig. 1 and 4, two cloth holders 7 are further connected to the top of the main body 1 for facilitating the disassembly and assembly of the filter cloth. In order to facilitate the connection and matching of the filter plate and the filter press frame and the disassembly and assembly of the filter plate, handles 6 are further connected to the two sides of the main body 1.
In another embodiment, as shown in fig. 5, the outer end surface of the sealing flange 12 is a plane structure, and after the adjacent filter plates are tightly attached, the sealing flange 12 can extrude the filter cloth in the middle into a step-shaped profile, and the sealing effect at the position can also be improved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
