Embodiment 1

[0011] Embodiment 1: with reference to attached Figure 1-3 . A high-input and fast-out filter cloth filter plate, which includes a filter cloth filter plate 1, which is provided with a feed port and a discharge port, and the feed port in the filter cloth filter plate 1 is directly connected to the pressing chamber And a feed valve 2 is installed on the feed port. 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 filter cloth filter plate, when the material cavity formed between the filter cloth filter plate and the filter cloth filter plate needs to be fed, the supply The feeding nozzle in the feeding system is quickly docked with the one-way feeding valve on the filter plate. After the docking is completed, the material is injected into the material cavity formed by the filter cloth filter plate and the filter cloth filter plate through the feeding valve under pressure. After the material is finished, the feeding 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 filter cloth filter plate and the filter cloth filter plate through the feed valve after being pressurized by a high-pressure pump. T...

Abstract

The invention relates to a high-in quick-out filter cloth filter plate and a high-speed feed method, which can feed at high speed and discharge quickly. The high-in quick-out filter cloth filter plate comprises a filter cloth filter plate, wherein the filter cloth filter plate is provided with a feed port and a discharge port, the feed port in the filter cloth filter plate is directly communicated with a squeezing cavity, and a feed valve is positioned on the feed port. The high-in quick-out filter cloth filter plate and the high-speed feed method have the advantages that firstly, an example of filter cloth filter plate direct feed is provided, feed efficiency is high, feed is smooth, and energy consumption is low; secondly, a check valve is adopted as a valve of the feed port so as to meet requirements of high-speed feed, and after feed is finished, the valve can be locked automatically so as to meet squeezing requirements of the filter cloth filter plate; and thirdly, the discharge port is arranged at the lower portion of the filter cloth filter plate, thereby being quick in discharge speed and free of energy consumption.

Description

technical field [0001] The invention relates to a high-input and fast-out filter cloth filter plate with high-speed feeding and fast discharge and a high-speed feeding method, belonging to the field of filter cloth filter plate manufacturing. Background technique [0002] The applicant owns CN101385913A, titled "Angle feed filter cloth filter plate assembly composed of flat diaphragm and filter plate", which includes flat filter cloth filter plate and filter cloth filter plate, flat filter cloth filter plate and filter cloth filter plate They are all single-angle feeding through holes, and the flat filter cloth filter plate and the filter cloth filter plate are arranged in a cross 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...
