Description
Technical Field
The utility model belongs to the field of filtering equipment (fluid machinery) in the solid-liquid separation process, and relates to a filter plate on a membrane filter press.
Background
The filter press is a universal solid-liquid separation device and is widely applied to the industries of chemical industry, metallurgy, pharmacy, dye, food, brewing, ceramics, environmental protection and the like. The filter plate is a core composite element of the filter press, and the core plate and the diaphragm are combined into the diaphragm filter plate. The filter plates are arranged on a cross beam of the filter press and generally adopt a combination of a diaphragm filter plate and a solid box-type filter plate, and the concave parts of the two filter plates form a filter chamber; the convex part of the filter plate supports an elastic pressing diaphragm attached with the filter cloth. The membrane filter press is a pressurizing and volume-changing filter device, and the filtering process is as follows: the filter chamber is externally pressurized and input with a filter material for low-pressure filtration through a feed hole of the filter chamber, the filter cloth intercepts particles in the material to form a filter cake, filtrate flows out of liquid holes at four corners of the filter plate, high-pressure liquid or gas medium is introduced into a high-pressure medium hole of the chamber to press the filter cake by a diaphragm membrane, the filter chamber bears the filter cake, and the filter plate is pulled open to realize gravity cake discharge.
The existing filter press diaphragm filter plate has no pressurizing tympanic membrane pressure detection device, when the diaphragm plate membrane is damaged and leaked, the diaphragm plate can not be detected, only when the manual detection shows that the loss of the squeezing medium is more or the material is unqualified due to the increase of the water content caused by insufficient pressure, the machine can be stopped to check the appearance of the filter plate one by one, and the diaphragm plate prohibits pressurizing tympanic membrane under the non-feeding state, thereby having some defects which are difficult to be found.
SUMMERY OF THE UTILITY MODEL
The utility model aims at improving current pressure filter diaphragm filter plate, solving corresponding technical problem, providing a take pressure measurement device's diaphragm filter plate.
The utility model provides a technical scheme that prior art problem adopted is: the diaphragm filter plate comprises a sealing frame, a core plate, a diaphragm, diaphragm supporting points, a feeding hole, four-corner liquid outlet holes, a high-pressure medium inlet hole and pressure detection holes.
Further, the pressure detection hole is provided with a steel ball sealing pressure measuring joint, the joint can achieve the effect of sealing a high-pressure medium when pressure measurement is not needed, when pressure measurement is needed, the pressure measuring joint is connected with the pressure gauge through a pressure measuring hose, whether the diaphragm is damaged or not is judged according to a pressure value displayed by the pressure gauge, and if damage and leakage exist, the pressure value is lower than a set pressure value.
The utility model provides a corresponding pressure filter is installed to the diaphragm filter plate, according to the display value of manometer, can detect the diaphragm filter plate of damage under the state that does not need the shut down, has improved production efficiency.

Detailed Description
The technical solutions in the embodiments of the present invention are described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some preferred embodiments of the present invention, but not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.
Examples
A diaphragm filter plate mainly comprises four-corner liquid outlet holes 1, a feed hole 2, a sealing frame 3, pressure measuring hose points 4, a pressure gauge 5, a steel ball sealing pressure measuring joint 6, a pressure detecting hole 7, a squeezing joint 8, a high-pressure medium inlet hole 9, a diaphragm 10, a core plate 11, a diaphragm support table 12 and a high-pressure chamber 13. The diaphragm filter plate is a combined structure of a core plate 11 and two diaphragms 10 which form a closed inner high-pressure chamber 13 through hot melt adhesion. The core plate 11 is a solid plate, one side of the core plate is provided with a high-pressure medium inlet hole 9, and a high-pressure chamber 13 internally connected with two surfaces of the core plate 11 is connected with an external pressure pipeline through a pressing joint 8. The other side surface of the core plate 11 is provided with a pressure detection hole 7 which is provided with a steel ball sealing pressure measuring joint 6, and when pressure measurement is needed, the steel ball sealing pressure measuring joint 6 is connected with a pressure gauge 5 by a pressure measuring hose 4. Under the working state, the diaphragm plates and the van-type plates are arranged on the cross beam of the filter press at intervals, the two plates are sealed through the sealing frame 3, and the inner concave cavity forms a filter chamber. When the material is filled in the concave cavity (filter chamber) through the feeding hole 2, the filter press stops feeding, the side pressing joint 8 of the diaphragm plate is communicated with an external pipeline, when high-pressure medium is introduced through the high-pressure medium inlet hole 9, the core plate 11 is fixed, the diaphragms 10 on the two sides expand towards the direction far away from the core plate 11 respectively, the material in the filter chamber is compressed, and the dehydration of the material is realized under the action of pressure. The steel ball sealing pressure measuring joint 6 is in a closed state when not connected with the pressure measuring hose 4, the pressure measuring hose 4 and the pressure gauge 5 are connected, then the pressure gauge 5 is observed, the pressing condition of the diaphragm plate on the material can be known according to the change of pressure, and whether the diaphragm 10 of the diaphragm plate is damaged or not can be judged.
