Description

An air filter with a diversion duct to improve internal gas flow

technical field

The utility model relates to the technical field of air filtration, in particular to an air filter with a guide pipe for improving internal gas flow.

Background technique

Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields to provide clean air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling air with impurity particles during work and increasing the chance of abrasion and damage. The main components of the air filter are the filter element and the casing. The filter element is the main filtering part, which is responsible for the filtration of gas, and the casing is the external structure that provides the necessary protection for the filter element. Among the tens of thousands of parts of the car, the air filter is a very inconspicuous part, because it is not directly related to the technical performance of the car, but in the actual use of the car, the air filter is very important to the car. (especially the engine) has a great impact on the service life. On the one hand, if there is no filtering effect of the air filter, the engine will inhale a large amount of air containing dust and particles, which will cause serious wear and tear on the engine cylinder; on the other hand, if it is not maintained for a long time during use, the air filter will The filter element of the cleaner will be full of dust in the air, which not only reduces the filtering ability, but also hinders the circulation of the air, causing the mixture to be too thick and the engine to work abnormally. Therefore, it is very important to maintain the air filter on schedule. The air inlet and outlet of the common air filter are smaller than the filter housing, so the position of the air passing through the filter element is relatively single, resulting in the air being concentrated in a fixed position of the filter element for filtration, resulting in insufficient utilization of the filter element. The problem of shortened service life.

For this reason, we propose a kind of air cleaner with diversion duct to improve the internal gas flow and put it into use to solve the above-mentioned problems.

Utility model content

The purpose of this utility model is to provide an air filter with a guide pipe to improve the internal gas flow, so as to solve the problem that the air flows in the inner cavity of the filter in a single direction and causes the air to concentrate on a certain fixed position of the filter element proposed in the background technology. Filtration at the wrong position has formed the problem of insufficient utilization of the filter element and shortened service life.

In order to achieve the above purpose, the utility model provides the following technical solutions: an air filter with a guide pipe to improve the internal gas flow, including a housing, the bottom end of the right side wall of the housing is provided with an air inlet, The bottom end of the inner cavity of the housing is provided with an air intake duct, and the mouth of the air intake duct is fixedly connected to the air inlet through an elbow, and the top of the air intake duct is provided with a spinner, and the spinner is located in the housing The inner cavity of the spinner, the bottom end of the spinner is fixedly connected with an air guide cone by bolts, a spinner sleeve is provided on the outside of the spinner, and the spinner sleeve is integrally formed with the blades of the spinner, The bottom end of the spinner sleeve is fixedly connected to the air intake duct through an elbow, and the two adjacent blades of the spinner and the inner wall of the spinner sleeve form an air guide duct. A filter element is provided at the top, an air outlet is provided at the top of the left side wall of the housing, and protective covers are provided at the top and bottom of the housing.

Preferably, both the top diameter of the spinner and the top diameter of the spinner sleeve are the same as the inner diameter of the casing.

Preferably, the diameter of the top of the air guiding cone is the same as the diameter of the nozzle of the air intake duct, and the bottom end of the air guiding cone is facing the nozzle of the air intake duct.

Compared with the prior art, the utility model has the beneficial effects that: by setting the air guide cone at the mouth of the intake duct, the air is guided to the air guide duct formed by the spinner blade and the inner wall of the spinner sleeve Inside, the air is evenly discharged through the air guide pipe, and then enters the filter element, so that the filter element can be fully utilized, avoiding the concentration of air in a certain position of the filter element for centralized filtration, and increasing the service life of the filter element.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: an air filter with a guide pipe to improve the internal gas flow, including a housing 1, the bottom end of the right side wall of the housing 1 is set There is an air inlet 2, and the bottom end of the inner cavity of the housing 1 is provided with an air inlet conduit 3, and the mouth of the air inlet conduit 3 is fixedly connected with the air inlet 2 through an elbow, and the top end of the air inlet conduit 3 is provided with A spinner 6, and the spinner 6 is located in the inner cavity of the housing 1, the bottom end of the spinner 6 is fixedly connected with the air guide cone 4 by bolts, and the spinner 6 is provided with a spinner on the outside Sleeve 5, and the spinner sleeve 5 is integrally formed with the blade of the spinner 6, the bottom end of the spinner sleeve 5 is fixedly connected with the air intake duct 3 through an elbow, the spinner 6 Two adjacent blades and the inner wall of the spinner sleeve 5 form an air guide duct 10, the top of the spinner 6 is provided with a filter element 7, and the top of the left side wall of the housing 1 is provided with an air outlet 8, so Both the top and the bottom of the housing 1 are provided with protective covers 9 .

Wherein, the top diameter of the spinner 6 and the top diameter of the spinner sleeve 5 are both the same as the inner diameter of the shell 1 . The diameter of the top of the air guide cone 4 is the same as the diameter of the mouth of the air intake duct 3, and the bottom end of the air guide cone 4 is facing the mouth of the air intake duct 3.

Working principle: When the filter is working, the air enters the intake duct 3 from the intake port 2, and reaches the nozzle of the intake duct 3 through the intake duct 3. Since the air diversion cone 4 is located at the nozzle of the intake duct 3, The air coming out of the nozzle of the air intake duct 3 will be dispersed by the air guide cone 4, enter the spinner sleeve 5, and then enter the air guide duct formed by the spinner 6 blades and the inner wall of the spinner sleeve 5 10. Since the top diameter of the spinner 6 and the top diameter of the spinner sleeve 5 are the same as the inner diameter of the shell 1, and the blades of the spinner 6 are distributed in a spiral enlarged form, the air will flow through the air guide pipe 10 Change the flow direction so that the air flows spirally in the air guide pipe 10, and then flows out evenly from the nozzle of the air guide pipe 10, enters the filter element 7 for filtration, and then the air filtered by the filter element 7 flows from the other end of the filter element 7 Flow out, enter the top of the inner cavity of the housing 1, and finally discharge from the air outlet 8. When the filter element 7 needs to be replaced, the protective cover 9 can be opened to replace the filter element 7.
