Embodiment 1

[0011] Embodiment 1: with reference to attached Figure 1-3 . A high-input and fast-out membrane filter plate, which includes a membrane filter plate 1, a feed inlet and a discharge outlet are arranged in the membrane filter plate 1, and the feed inlet in the membrane filter plate 1 is directly connected to the pressing chamber and the feed inlet There is a feed valve 2 on it. The feed valve 2 is a one-way valve or an electromagnetic feed valve. The feed valve 2 is located on the upper end surface of the filter plate 1 . The outlet 3 is located at the bottom of the filter plate 1 .

Embodiment 2

[0012] Embodiment 2: On the basis of Embodiment 1, the one-way valve is composed of a pipe joint and a tapered rubber sleeve. The upper part of the pipe joint is a feed butt joint socket located outside the filter plate, and the lower part is covered with a high-elastic conical rubber head. And located in the filter plate, the cone head of the conical rubber head is stretched under the pressure of the high-pressure material fluid, and automatically returns to its original shape after the feeding is completed-that is, it is closed to prevent the material from flowing backward.

Embodiment 3

[0013] Embodiment 3: On the basis of Examples 1 and 2, a high-speed feeding method of a high-input and fast-out diaphragm filter plate, when the material cavity formed between the diaphragm filter plate and the diaphragm filter plate needs to be fed, in the feeding system The feed nozzle of the feeder is quickly docked with the one-way feed valve on the filter plate. After the docking is completed, the material is injected into the material cavity formed by the diaphragm filter plate and the diaphragm filter plate through the feed valve. The material valve is locked, and then the tympanic membrane is pressed, and the squeezed liquid is quickly discharged through the discharge port. The pressurized material means that the material is injected into the material cavity formed by the diaphragm filter plate and the diaphragm filter plate through the feed valve after being pressurized by the high-pressure pump. The feed valve 2 is a one-way valve or an electromagnetic feed valve.

Abstract

The invention relates to a high-speed feeding and fast discharging membrane filter plate which is capable of feeding at high speed and fast discharging, and a high-speed feed method, the high-speed feeding and fast discharging membrane filter plate comprises a membrane filter plate, the membrane filter plate is internally provided with a feeding hole and a discharging hole, and the feeding hole in the membrane filter plate is directly communicated with a squeezing cavity and is provided with a feeding valve. The membrane filter plate and the high-speed feeding method have the advantages that: 1. a precedent for the direct feeding of the membrane filter plate is created, not only is high in feeding efficiency, and smooth in feeding, but also is low in energy consumption; 2. a one-way valve is used as the valve of the feeding hole, not only be the requirement of fast feeding can met, but also the valve can be automatically locked after the feed is finished, and the squeezing requirement of the membrane filter plate can be met; and 3. the discharging hole is arranged at the lower part of the membrane filter plate, so the discharging speed is high, and the energy can not be consumed.

Description

technical field [0001] The invention relates to a high-input and fast-out membrane filter plate with high-speed feeding and fast discharge and a high-speed feeding method, belonging to the field of membrane filter plate manufacturing. Background technique [0002] The applicant owns CN101385913A, titled "angle-feed diaphragm filter plate assembly composed of flat diaphragm and filter plate", which includes flat diaphragm filter plate and filter cloth filter plate, and both flat diaphragm filter plate and filter cloth filter plate are single Corner feed through holes and flat diaphragm filter plates and filter cloth filter plates are arranged in a crossed manner. Advantages: first, the channel has a self-cleaning function, which can keep the channel unimpeded; second, it can filter the slurry quickly; third, it is not only convenient to wash the filter cake in the forward direction, but also can wash the filter cake in the reverse direction, so that the filter cake in the fil...
