Description

TECHNICAL FIELD

[0001] The utility model relates to small -size filter device technical field especially is related to a frame frame structure and clear filter system of blowing. BACKGROUND

[0002] In the application scene of heavy truck, especially in the harsh working environment of mine and other smoke, heavy truck usually needs long time continuous operation. In this process, the surface of its radiator often adheres a layer of thick dust. At the same time, the heavy truck engine generates a large amount of heat energy when running, and the radiator is the key component of heat dissipation. Once the dust on the surface of the radiator accumulates too much, the heat dissipation will be blocked, causing the engine coolant temperature to rise continuously, and then overheat occurs. This not only weakens the power output of the engine, but also is likely to cause serious mechanical failures such as cylinder pulling and shaft holding, greatly shortening the service life of the engine.

[0003] In order to solve this problem, filter device is widely used to intercept dust, particulate matter and other impurities in the environment to prevent pollutants from blocking the radiator channel and reducing heat exchange efficiency. However, the traditional filter device usually adopts multi-layer filter screen or filter core structure, which mainly realizes the filtering function through physical interception. However, when applied in the field of heavy truck, such device has the following problems:

[0004] Lack of cleaning means: the filter core is easy to cause pressure drop to rise and ventilation volume to decrease due to impurity accumulation in the long-term use process. This makes the equipment need to be frequently stopped for filter core replacement or manual cleaning, significantly increasing the maintenance cost, and also affecting the running continuity of the system.

[0005] Low space utilization: the existing filter device usually needs a large radial installation space, which is difficult to adapt to the structure demand of compact equipment. Worse still, if the cleaning structure is increased, it will further increase the occupied space.

[0006] Energy consumption and efficiency contradiction: the ratio of the total area of the jet opening to the cross-sectional area of the inlet pipe is unreasonable. If the total area of the jet opening is too large, the airflow velocity will be insufficient, resulting in poor blowing effect; and if the total area of the jet opening is too small, it will also cause insufficient wind volume released at a time, which will also affect the blowing effect. INVENTION CONTENTS

[0009] The filter frame is provided with a containing cavity, and an air flow channel is arranged in the filter frame to meet the air flow;

[0010] The filter core is arranged in the containing cavity of the filter frame;

[0011] The air flow channel is communicated with the compressed gas, and a jet opening is arranged on the inner wall of the filter frame and communicated with the air flow channel, the compressed gas entering the air flow channel of the filter frame forms a high-speed air flow blowing to the filter core through the jet opening.

[0012] As a more preferred mode, the profile of the jet opening includes one or a combination of straight grooves, curved grooves, special-shaped grooves, round holes, square holes and special-shaped holes.

[0013] As a more preferred mode, the filter core adopts a flat plate structure, and the high-speed air flow formed by the compressed gas through the jet opening can blow the filter core surface, thus greatly saving the space required for arranging the filter core and blowing equipment in the containing cavity, providing conditions for arrangement in limited space equipment, while ensuring the blowing effect.

[0014] As a more preferred mode, the jet opening includes two strip-shaped grooves arranged on opposite sides of the filter frame, and the high-speed air flow formed by the compressed gas entering the air flow channel of the filter frame blows from both sides of the filter core to the center and is directly discharged outward at the center of the filter core, avoiding the accumulation of dust and impurities on the other side of the filter core caused by one-sided blowing.

[0015] As a more preferred mode, the frame blowing filter core frame structure further includes a front protective net and a rear protective net, wherein the filter frame is provided with a front opening and a rear opening communicated with the containing cavity, and the front protective net and the rear protective net cover the front opening and the rear opening respectively, wherein the front protective net and the rear protective net can fix the filter core on one hand to avoid falling off, and on the other hand, they are also convenient to disassemble, thereby facilitating the replacement or maintenance of the filter core.

[0016] As a more preferred mode, the filter frame includes a plurality of hollow air pipes, and the plurality of hollow air pipes are communicated with each other to form a closed structure or a semi-closed structure, wherein the semi-closed structure has lower manufacturing cost and is more convenient to produce, and the closed structure can ensure that the compressed gas flows more smoothly in the air flow channel.

[0017] As a more preferred mode, the frame blowing filter core frame structure further comprises a gas pipe nozzle fixed on the filter frame and communicated with the airflow channel, and the compressed air enters the airflow channel through the gas pipe nozzle.

[0018] As a more preferred mode, the sum of the areas of the gas outlet sections of all the gas injection openings S1 and the gas inlet section of the gas pipe nozzle S2 satisfy the relationship S1 < 5S2, so that a high-speed airflow blowing to the filter core can be formed to meet the minimum requirement for dust blowing.

[0019] As a more preferred mode, the sum of the areas of the gas outlet sections of all the gas injection openings S1 and the gas inlet section of the gas pipe nozzle S2 satisfy the relationship S1 < 5S2, so that a high-speed airflow blowing to the filter core can be formed to meet the minimum requirement for dust blowing.

[0020] To solve the above problems, the utility model further provides a filter cleaning system, comprising:

[0021] The frame blowing filter core frame structure described above;

[0022] A power pack, the power pack stores compressed gas, and the airflow channel is communicated with the power pack;

[0023] The filter cleaning system further comprises a control unit electrically connected with the power pack, used to control the opening and closing, interval and duration of the power for releasing the compressed gas.

In this process, the pressure energy in the compressed gas forms a high-speed airflow when the compressed gas passes through the gas injection openings, according to the fluid continuity principle and Bernoulli equation, because the cross-sectional area of the gas injection openings is small, the high-speed airflow obtains a large kinetic energy, and the high-speed airflow directly acts on the surface of the filter core. When the airflow impacts the dust and impurities, an impact force is applied to the dust and impurities, which can overcome the adhesion and friction between the dust and the surface of the object, so that the dust and impurities are separated from the surface of the object. Secondly, the gas injection openings are directly arranged on the filter frame, and the filter frame not only supports the overall structure, but also transmits the compressed gas and injects the high-speed airflow, greatly simplifying the structure volume and providing the possibility of integration in a limited space device.

[0025] This utility model's filtration system utilizes a power pack containing compressed gas instead of an air compressor during operation, reducing the overall system size. The separate design of the power pack allows for independent installation of the power pack and the parallel purging filter frame structure, further improving space utilization. Secondly, by controlling the interval between the opening and closing of the compressed gas release via the control unit, the frequency of each purging cycle can be adjusted, thereby achieving a suitable frequency based on the current working environment, ensuring purging effectiveness while reducing losses. Furthermore, by adjusting the duration of each compressed gas release cycle, the effectiveness of each purging cycle can be adjusted to ensure optimal dust removal.

[0026] The parallel purge filter element frame structure and filtration system of this utility model integrate airflow channels and jet openings on the filter frame, which can not only achieve purge cleaning of the filter element, but also greatly simplify the structural volume, solving the problems of existing filtration devices lacking effective cleaning methods and occupying a large installation space.
