Product description and use:

Quick opening (vertical) candle filter is also called thickening filter, filter element type self-cleaning filter, filter cake layer filter.There are several candle tubes (metal and non-metal) in the shell, which are suitable for different fields

Meet the requirements. The candle tube is covered with a filter cloth to filter filtrate and solids. Drying of filter cake after filtration, discharge, cleaning of filter cloth, etc

Can be fully automatic operation. Because there is no driving device and the structure is simple, it can deal with the situation of large filtering area.

With the patented structure design of candle type filter and candle type core, it can realize no residual liquid discharge in the shell, without affecting the upper and lower batches of materials

There is no barrier structure at the bottom of the filter element. At the same time, the bottom of the filter element can be manually and pneumatically powered for slag removal, and the slag discharge port is very large. And the filter element is also

Vertical installation, which is very conducive to vertical slag removal, is the equipment closest to the requirements of full sanitary level among all filtering equipment

Typical applications, such as beer clarification, electrolyte impurity removal, metal degreasing and slag removal, phosphating and slag removal, chemical product concentration and thickening, etc

It is very suitable for this series of products. A variety of candle filter structure (stainless steel 304316l, plastic PP,

PPS, PTFE, etc.) are of various styles, and there is always one suitable for your filtering requirements.

Product characteristics

Candle filter is a kind of high efficiency, energy saving, automatic closed filtration precision clarification device

Prepare. It has the following characteristics:

1. Completely sealed filtration, no leakage, no environmental pollution.

2. The filter element is designed with double structure (internal metal mesh support + external filter cloth), It has wide application field and good filtering effect.

3. It can realize complete filtration at one time.

4. Filter cake can be washed and dried to obtain the maximum economic benefit.

5. It adopts gas back blowing to remove slag, which is clean and fast, and is suitable for many kinds of viscous materials.

6. The whole filtration process can be fully automated (according to the pipeline automatic configuration.

Scope of application

Food industry: decolorization and filtration of sugar solution such as sugar and glucose, clarification and filtration of alcohol, juice and beverage, etc.

Chemical industry: petrochemical industry, inorganic chemical industry, organic chemical industry, crystal separation in each filtration, filtration of various catalysts

From, chemical products decolorization filtration electrolyte impurity removal, metal degreasing slag removal, phosphating slag removal, chemical products concentration, thickening, etc

Detailed description of the functions of the candle filter system of Shanghai double start fluid separation technology:

This unique filter unit is the heart of the candle filter filtration system. 

The (plum shaped) filter unit ensures that the filter cake can be attached to the filter cloth while filtering safely

On the surface, this feature is also the basis for effective discharge of filter cake.

The filtering unit with petal shaped (plum shaped) cross section is beneficial to the adhesion of filter cake in the filtering process:

The concave part of the filter unit enables the filter cake to adhere when under pressure and ensures that the filter cake will adhere during the whole cycle

Keep attached.

When the filtrate passes through the filter cloth, it flows to the bottom of the candle filter rod through a plurality of peripheral perforated pipes,

After that, it flows upward through the central pipe into the liquid collecting rod.

Multiple external perforated pipes can make filtrate flow down to the bottom under the action of gravity; filtrate under the action of pressure

The lower part flows upward through the central pipe into the collecting rod.

Whether the program is set to dry or wet discharge, the discharge is reversed by introducing into the candle type filter rod

Pressure to achieve.

The unique structure strengthens the reverse flow, which leads to the rapid outward expansion of the filter cloth, especially in the filter cake attachment

The landing area causes the filter cake to crack vertically.

The instantaneous back blowing gas (such as air or nitrogen) in the filter cloth makes the cracked filter cake quickly throw away from the filter cloth.

In the discharge process, there are no other moving parts except for the expansion of the filter cloth.

Maintenance

The basic concept of the candle filter is that there are no moving parts, and because of this factor, the filter only needs

Less maintenance work.

In particular, the use of new synthetic materials for internal components increases the reliability and service life of the filter.

Note: if necessary, please consult our technical department for detailed technology. At the same time, our company has developed a full-automatic candle filter system module,

Fully automatic and high-precision backwashable filter equipment is realized. At the same time, according to customer requirements, any number of filter elements and different length gauges can be customized
