Matt Filtration Equipment Co., Ltd.

& Standard top-entry security filter
(1) Introduction
Universal top-entry security filter generally only produces single-bag numbered bags and numbered bags. There are also strict restrictions on import and export. It is: D flange or inner wire, the barrel is h* seamless pipe production, the turtle back is cast, the production cycle generally takes two weeks, the design pressure is.
The universal top-entry security filter is top-in and bottom-out. Compared with the previously produced top-entry bag filter, the process is more complicated, more convenient, and the production cycle is shorter.
The universal top-entry security filter works together with mechanical equipment. Generally, there is no need for such high-cost bag filters.
(2) Structure and working principle of bag filter
Bag filter is a multi-purpose machine with novel structure, small size, easy and flexible operation, energy saving, high efficiency, sealed operation and strong applicability. Filtration equipment. & Bag filter is a pressure filter device, which mainly consists of filter cylinder, filter cylinder cover and flange connection, stainless steel filter bag reinforcement mesh and other main components. The filtrate flows into the filter bag from the side inlet pipe of the filter shell. , the filter bag itself is installed in a reinforced mesh basket, and the liquid penetrates through the filter bag of the required fineness level to obtain qualified filtrate, and the impurity particles are intercepted by the filter bag. It is very convenient to replace the filter bag of this machine, and there is basically no material consumption for filtration.
(3)&Main Features of Bag Filter
The probability of side leakage of the filter bag is small, which effectively guarantees the filtration quality. &
Bag filter can carry greater working pressure, has small pressure loss, low operating cost and obvious energy saving effect. &
The filter bag has high filtration accuracy. The current accuracy of this machine is. It is also necessary to replace filter bags with different precisions according to the situation. Bag filter has a large processing capacity, small volume and large dirt holding capacity. &
Based on the working principle and structure of the bag filter system, it is convenient and quick to replace the filter bag, and the filter does not need to be cleaned, saving labor and time. &
The filter bag can be used repeatedly after cleaning, saving costs. &
Bag filter has a wide range of applications, flexible use, various installation methods
and simple operation. &
Due to the above characteristics, it is widely used in filtration of petroleum products, chemical products, paints, food and beverages, and sewage treatment.
Suitable for filtration of any fine particles, and the accuracy can be adjusted according to the filter bag Range from

(5) Key points for bag filter operation
.&Choose the appropriate delivery pump according to the flow rate. Connect the liquid inlet on the filter and install a regulating valve.
.& Thoroughly clean the filter housing.
.&Connect the inlet and outlet of the housing to the filtration system pipeline, pay attention to the direction to ensure that the filter bag is on the inside The status of the water inlet and outer water outlet.
.&Place the mesh basket into the filter and ensure that it is in place.
.&Install the matching filter bag into the mesh basket (note that the filter bag must be Use the supporting basket together and keep it close to the inner wall of the basket.
.&Place the filter bag and pressure ring and press them tightly.
.&Install the upper cover and ensure that the ring is in place.
/> .&Open the exhaust valve at the top of the housing.
.&Open the inlet valve slightly to allow the liquid to enter the housing until the liquid comes out of the exhaust valve. At this time, close the exhaust valve.
.& Slowly open the outlet valve until it is fully open.
.&Adjust the inlet valve until it is fully open (when opening the valve, it is necessary to prevent sudden pressure from damaging the filter bag.
.&When the filter bag pressure difference is within .kg /㎝Replace the filter bag
.&When replacing the filter bag, be sure to release the pressure in the filter housing, and do not open the filter cover under pressure.
