Description

Cartridge filter

technical field

The utility model relates to a filter core type filter, which belongs to the field of filtering equipment.

Background technique

In the prior art, the cartridge type filter belongs to finer filtering equipment, which can remove suspended solids (silt, rust, etc.), colloids (mainly substances with small particle sizes), some organic matter (can remove some colors, odors, etc.) , to improve the appearance and taste of the water), etc. Cartridge filters are suitable for beverage water, domestic water, ultra-pure water equipment security systems, oil field water injection, chemical liquid, electroplating liquid and other liquid filtration in electronics, petroleum, chemical, pharmaceutical, and food industries.

During the use of the filter element filter, as the impurities retained by the filter increase, the filter element assembly will gradually clog. When it cannot meet the filtering requirements, the filter element needs to be cleaned or replaced before it can continue to be used. In the prior art, every time the filter element is cleaned or replaced, the filter needs to be opened, and the filter element needs to be taken out for cleaning or replacement.

However, when extracting the filter element, tools such as pliers are generally used to disassemble the filter element, which is not only difficult, time-consuming and laborious to disassemble, but also easily damaged by tools such as pliers during the disassembly process, which requires high technical requirements for operators , if the operation is not done properly, it may also cause bodily injury to the operator.

In addition, in order to strengthen the airtightness of the filter device and avoid the short circuit of the filter, the existing filter often needs to install a sealing ring between the end of the filter element and the flower plate; since there are usually multiple filter elements installed in a single filter, so Just need to install multiple sealing rings additionally. Because the internal space of the whole filter is very compact, it is difficult to disassemble and assemble the sealing ring. In addition, there are a large number of sealing rings that need to be disassembled, which is easy to cause omissions when disassembling and assembling the sealing ring, which ultimately affects the airtightness of the filter. sex.

Therefore, it is obviously of positive practical significance to develop a filter element which is easy to assemble and disassemble.

The pull rod is a hollow tube structure, and a plurality of diversion holes are arranged on it;

A through hole is provided on the support plate, and the filter element extracting device is inserted on the outside of the draft tube through the through hole;

The filter element is sheathed on the filter element extraction device, and the bottom of the filter element is against the support plate.

In the above, one filter element or multiple filter elements can be set in parallel in the filter housing as required. The shape of the supporting plate in the filter element extraction device can be set as required.

Preferably, there is still a sealing layer between the bottom of the filter element and the support plate. For example, a layer of sealing material can be coated on the outer surface of the support plate. The sealing material can be nitrile rubber, fluorine rubber, silicon rubber, natural rubber or polyurethane rubber.

Preferably, the connecting member is a screw. Of course, the structure of the connecting piece can be a through hole in the side wall, or a screw with external thread, or a screw with internal thread, or any other suitable connecting piece form.

In the above technical solution, the filter housing is mainly composed of an upper housing and a lower housing, and the upper housing and the lower housing are connected by a flange; the upper housing is provided with a feed port, and the lower housing is provided with a There is a discharge port.

Preferably, the discharge port is located at the bottom of the lower casing.

The above technical solution also includes a filter element locking device, which is arranged on the top of the filter element.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

1. The utility model designs a new filter element type filter, and the filter element can be easily extracted through the filter element extraction device by setting a matching filter element extraction device in the housing, thereby greatly facilitating the disassembly and assembly of the filter element and achieving remarkable advantages. Effect;

2. It has been proved by practice that the filter extraction device of the utility model is completely built into the filter housing, making full use of the gap between the filter cores inside the filter housing, greatly improving the utilization rate of the inner space of the filter housing, and Airtightness inside the filter is not negatively affected;

3. The utility model can cover the outer surface of the support plate of the filter element extraction device with sealing material, which also has the function of a sealing ring, which can not only effectively strengthen the airtightness of the filter, avoid short circuit of the filter, but also reduce the use of the sealing ring , to avoid the problems caused by the disassembly and assembly of the sealing ring;

4. The pull rod of the utility model is a hollow pull rod with a diversion hole on the surface, which also has the function of a diversion tube, which improves the removal efficiency of the filter element and does not affect the filtration efficiency of the filter element;

5. The utility model has the advantages of simple structure, low cost, convenient transformation, and is suitable for popularization and application.
