Granulating water filling device and granulating system

Abstract

The invention provides a granulating water filling device and a granulating system, and relates to the technical field of granulating water filtering. A first water inlet pipe of the granulating waterfilling device is communicated with the upper part of a first filter, and a second water inlet pipe is communicated with the upper part of a second filter; a first water outlet pipe and a second water outlet pipe are communicated with the first filter and the second filter respectively; one end of a first drain pipe is communicated with the lower part of the first filter, and the other end is communicated with a main drain; one end of a second drain pipe is communicated with the lower part of the second filter, and the other end is communicated with the main drain; valves are arranged on thefirst water inlet pipe, the second water inlet pipe, the first water outlet pipe, the second water outlet pipe, the first drain pipe, the second drain pipe and the main drain respectively. By means ofthe arrangement, safety and stability are realized during switching between the two filters; when the reserve filter is filled with water, less influence is produced on pressure and flow of a granulating water system; besides, transformation of the conventional device is easy to realize.

Description

technical field [0001] The invention relates to the technical field of granulation water filtration, in particular to a granulation water filling device and a granulation system. Background technique [0002] Existing grain cutting water filter adopts two filters, one for use and one for standby. The filter in use is gradually clogged, and the pressure difference rises. When the instrument alarms for the first time, switch to another filter, isolate the clogged filter, drain it and clean it. After cleaning, fill the filter with water and dispose of it. Standby. [0003] figure 1 It is the structural representation of the cutting water filling device in the prior art; as figure 1 As shown, in the prior art, the cutting water filling device includes a first water inlet pipe A, a second water inlet pipe B, a first water outlet pipe C, a second water outlet pipe D, a first filter E, and a second filter F. The first drain pipe G and the second drain pipe H; the first water in...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of granulation water filling device and granulation system, so as to improve the opening degree of the valve that the granulation water enters the first water inlet pipe or the second water inlet pipe during water filling in the prior art. control, it is easy to trigger the monitoring interlock and cause the technical problem of stopping the whole pelletizing system
