Description

A kind of air cleaner that can reduce pressure loss

Technical field

The utility model relates to a kind of air cleaner, has related in particular to a kind of air cleaner that can reduce pressure loss.

Background technology

Compressed air is the second largest power source that is only second to electric power, be again the technique source of the gas that serves many purposes, its range of application spreads all over industry and the departments such as environmental protection, automobile making, oil, chemical industry, metallurgy, electric power, machinery, light industry, weaving, electronics, food, medicine, biochemistry, national defence, scientific research.As everyone knows, under any operating mode, contain a considerable amount of impurity in the compressed air of unprocessed mistake, as: water, rust, particle dust and oil, directly do not use if do not remove these impurity, airborne impurity can cause very large harm to the air force element in the system, and this just needs to use the filtration, purification system, and filter is filtering purifying equipment important in the filtration, purification system.

Chinese patent application number is called " filter that improves structure " for the patent of invention of " 201110216849.9 " discloses name, comprise tube head, pipe shaft and filter core, filter core and tube head are tightly connected, tube head is by sealing combination at upper end and base plate after outer cylinder and the inner cylinder arranged concentric, the lower end is uncovered setting, the filter core cross section is the U-shaped structure, comprise at the bottom of filter core mouth and the filter core, this filter core oral area is connected with the inner circle seal of tube of tube head, the cross section of pipe shaft also is that the sheathed outer pipe open end with the filter core outside and cylinder outer wall and tube head of U-shaped and this pipe shaft is tightly connected, the pipe shaft interior diameter is greater than the filter core overall diameter, Formation cross-section is the cavity of annulus between pipe shaft inwall and the filter core outer wall, it is characterized in that: the link of pipe is provided with connecting portion in this filter core and the tube head, adopt Easy-dismounting structure directly to be fixedly connected with rear sealing in this connecting portion and the tube head between the pipe, this filter that improves structure is easier for installation quick, can significantly reduce the advantage of cost, in addition owing to there is not the obstruction of contiguous block, can greatly reduce the resistance of air Flow In A Circular Tube in tube head, reduce energy loss when filtering.

In the use procedure of reality, the filter core air inlet of air cleaner is installed in the inner cylinder (being the filter core connector) of tube head, the filter core air inlet of traditional air cleaner can become a step position in the filter core connector of tube head, when the compressed air that contains impurity enters in the filter filtration, purification, can meet obstructions in this step position, produce pressure loss (being called for short crushing or pressure drop), so that must additionally doing work, air compressor compensates, cause thus the air compressor power consumption to increase the compressor lost of life.With admission pressure 0.8Mpa, flow 12m ³The air cleaner of/min is example, and air cleaner is under the state that gas reaches capacity, and the force value during air inlet is that the pressure loss when giving vent to anger was 0.12Mpa after 0.8Mpa purified through the filter water conservancy diversion; The filter pressure loss that flow is larger is just larger, and the pressure loss of the more voluminous life of quantity of filter cleaning is just larger.

The utility model content

The technical problems to be solved in the utility model is in order to overcome technological deficiency recited above, a kind of air cleaner that can reduce pressure loss to be provided.

In order to solve technical problem recited above, the utility model is taked following technical scheme:

A kind of air cleaner that can reduce pressure loss, include tube head and with pipe shaft and the filter core of tube head assembly connection; Described filter core places in the pipe shaft, and described tube head further includes the pipe shaft connector and the filter core connector that are arranged at the lower end, be arranged at the air inlet of front end and be arranged at the gas outlet of rear end; Described filter core further includes the filter core body, be assemblied in filter core body upper end end-cap assembly, be assemblied in bottom assembly and the fastening screw of filter core body lower end; One end of described fastening screw is installed on the bottom assembly, its other end passes the filter core air inlet of filter core body and external part cap assemblies, the inner peripheral wall of described filter core connector is provided with step surface, and described filter core air inlet packs into the inwall of filter core connector and is connected with step surface.

Being arranged on the diameter of step surface of filter core connector inwall and the diameter of filter core air inlet matches.

Described filter core air inlet is sealed and matched with step surface and is connected.

The utility model is installed in the filter core air inlet of original air cleaner the inwall of the filter core connector of tube head, and at the inwall of the filter core connector of tube head one step surface is set, filter core air inlet and step surface are connected, and the filter core of installing so just can not form the step position at the filter core connector place of tube head.

Adopted the air cleaner of such scheme, the filter core connector of the tube head of air cleaner is connected with wheel chair access being sealed and matched of filter core air inlet, in the use procedure of reality, when the compressed air that contains impurity enters filter core by tube head, because the junction is not subject to the resistance of step position, thereby the pressure loss of gas when having reduced by air cleaner.Equally with admission pressure 0.8Mpa, flow 12m ³The air cleaner of/min is example, and air cleaner is under the state that gas reaches capacity, and the force value during air inlet is 0.8Mpa, and after purifying through the air cleaner water conservancy diversion, the pressure loss when giving vent to anger is 0.1Mpa.The utility model is simple in structure, and dependable performance can reduce the pressure loss of compressed air when filtering effectively, and the use cost that can significantly save the user reaches the purpose that realizes high-efficiency and economic.
