Description

Filter plate of high-pressure filter press

Technical Field

The utility model mainly relates to a high pressure filter plate field.

Background

At present, because the squeezing pressure of the existing high-pressure filter press is larger, about 8-10 MPa, in order to endure high-pressure filter pressing, a filter plate is usually made of metal materials, most of the filter plate is made of carbon steel, and a small part of the filter plate is made of stainless steel. For example, in the use process of titanium gypsum sludge filter pressing, the service life of the metal filter plate is short, the metal filter plate is corroded seriously in about 1 year generally, and the water discharge ring groove is blocked by corrosion, so that filtrate cannot be discharged, and the filter plate is scrapped. Even if the metal surface adopts the anti-corrosion processes such as nickel plating, chrome plating, plastic spraying and the like, the service life can not be effectively prolonged due to the general anti-rust effect of the severe use environment, and meanwhile, the production efficiency is greatly influenced by shortening the cleaning period. In order to solve the corrosion-resistant problem, some manufacturers adopt polypropylene to manufacture the filter plate, but because the squeezing force of the high-pressure filter press is more than 8MPa, and the filter plate has a special structure, and the filter plate is repeatedly opened and pulled, the pure plastic filter plate can not bear high pressure and can not be frequently operated, and the pure plastic filter plate can be cracked and scrapped within a few days.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model lies in: aiming at the defects in the prior art, the high-pressure filter press filter plate has the advantages of corrosion resistance, high strength and long service life.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a high-pressure filter press filter plate, includes die-casting fashioned plastics system filter plate main part and the metal system skeleton that is located the filter plate main part, the skeleton includes facing, pan feeding pipe, drain pipe and disc band iron frame, disc band iron frame and facing coaxial arrange and with facing fixed connection, pan feeding pipe and drain pipe are fixed in on the disc band iron frame, and the pan feeding pipe is linked together with the facing, be equipped with a plurality ofly in the filter plate main part with the coaxial annular water drainage tank of the different diameter sizes of arranging of facing, each annular water drainage tank is linked together with the drain pipe.

Furthermore, the disc-shaped flat iron frame comprises a plurality of flat iron rings which are coaxially arranged with the tooth socket and have different diameters, the flat iron rings are connected in series through flat iron rods, and the end parts of the flat iron rods are fixed on the tooth socket.

Furthermore, a plurality of grapples are fixed on the framework and used for grasping the filter plate main body.

Further, the filter plate body is made of reinforced polypropylene material.

Fig. 3 is a sectional view taken along line B-B of fig. 1.

Illustration of the drawings: 1. a filter plate body; 2. a framework; 3. a tooth socket; 4. a feeding pipe; 5. a drain pipe; 6. a flat iron ring; 7. a flat iron rod; 8. a grapple; 9. a water drainage groove.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, and it should be noted that the scope of the present invention is not limited to the following embodiments, and any modifications and decorations made by the present invention should be considered as the scope of the present invention without departing from the principle of the present invention.

As shown in fig. 1 to 3, the filter plate of the high pressure filter press of the present invention includes a plastic filter plate body 1 formed by die casting and a metal frame 2 located in the filter plate body 1. The preferred metal material of skeleton 2, skeleton 2 include facing 3, pan feeding pipe 4, drain pipe 5 and disc band iron frame, disc band iron frame with facing 3 coaxial arrangement and with facing 3 fixed connection, pan feeding pipe 4 and drain pipe 5 are fixed in on the disc band iron frame, and pan feeding pipe 4 is linked together with facing 3. The filter plate body 1 is made of reinforced polypropylene materials, a plurality of annular drainage grooves 9 which are arranged coaxially with the tooth socket 3 and have different diameters are formed in the filter plate body 1, and each annular drainage groove 9 is communicated with the drainage pipe 5.

As shown in fig. 2, preferably, the disc-shaped band iron frame comprises a plurality of band iron rings 6 with different diameters and sizes coaxially arranged with the tooth socket 3, wherein the band iron rings 6 are connected in series through a band iron rod 7, and the end part of the band iron rod 7 is fixed on the tooth socket 3. A plurality of grapples 8 are fixed on the flat iron ring 6, the feeding pipe 4 and the drain pipe 5 and used for grasping the filter plate body 1.

The utility model discloses a manufacture process does: firstly, welding a tooth socket 3, a feeding pipe 4, a drain pipe 5, a flat iron ring 6, a flat iron rod 7 and a grab hook 8 together according to the figure 2 to form a metal framework 2; then put into die casting die with welded skeleton 2 to pour into the plastics mixed solution of reinforcing polypropylene material and short glass fiber (or long glass fiber) into in die casting die, rethread high pressure die casting machine die-casting shaping goes out the filter plate main part 1 that has water drainage tank 9, punches the intercommunication drain pipe 5 on water drainage tank 9 at last. The outer portion of the formed filter plate is made of corrosion-resistant plastic materials, the metal framework 2 is embedded in the formed filter plate, the strength can also meet the use requirement, and the problem that the service life of the filter plate is short is fundamentally solved.
