[0025] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0026] like Figures 1 to 4As shown, the vehicle-mounted mechanical dust removal and purification device includes a main shell, which is a hollow vertical cylindrical structure; an air intake dust removal shell 2 is provided on one side of the main shell, an inlet 1 is provided at one end of the air intake dust removal shell, and a baffle structure is provided in the main shell. A cyclone separation structure is provided in the main shell, and the other end of the air intake dust removal shell is connected to the main shell corresponding to the cyclone separation structure, a dust discharge port 8 is provided at the lower end of the main shell, and a bag separation structure 10 is provided at the upper end of the main shell corresponding to the exhaust port of the cyclone separation structure.

[0027] The air intake dust removal shell 2 and the internal baffle structure form a primary dust removal structure, the cyclone separation structure in the main shell forms a secondary dust removal structure, and the bag separation structure 10 forms a tertiary dust removal structure; the vehicle-mounted mechanical dust removal and purification device is reasonably designed, adopts a multi-stage series dust removal system, and has high dust removal efficiency.

[0028] The air intake dust removal shell is a horizontally arranged cylindrical structure, and the baffle structure is a group of baffles 3 arranged alternately along the axial direction of the air intake dust removal shell. When the gas encounters the baffle, larger dust and seeds will fall under the action of gravity; an openable dust discharge door 11 is provided at the bottom of the air intake dust removal shell.

[0029] The cyclone separation structure includes a guide plate 4 and a cyclone dust removal cone. The guide plate is located above the cyclone dust removal cone. The guide plate is set near the other end of the air intake dust removal shell. The cyclone dust removal cone is an inverted cone structure. A vortex cover 6 is provided above the lower port of the inverted cone structure to improve the separation effect.

[0030] The cyclone dust collection cone includes two inverted cone structures arranged above and below, namely the first layer cyclone dust collection cone 5 and the second layer cyclone dust collection cone 7; the lower end of the inverted cone structure below forms an ash discharge port 8, which has complete separation and compact structure.

[0031] An inclined plate is provided at the other end of the main shell corresponding to the air intake dust removal shell, and the inclined plate is located above the guide plate; an exhaust port 9 is provided above the cyclone dust removal cone, and the exhaust port extends from the inclined plate and is arranged in the bag separation structure, and the inclined plate forms an inclined slide plate for dust to slide off.

[0032] The present invention adopts a multi-stage series dust removal structure integrated setting, which has a compact structure, and the entire device occupies a relatively small space, which is conducive to layout and installation; when the dust gas enters the second-stage dust removal separator from the first-stage dust removal separator, the dust gas will be expanded and reach the cylindrical turbulence on the exhaust port and will be counter-acted and decelerated on the back; a guide plate is set, and under the action of centrifugal force, it enters the conical part. The design of the vortex cover is conducive to the formation of an ascending vortex, which is beneficial to separation efficiency and thorough dust removal.

[0033] Preferred embodiments of the present invention are:

[0034] The dust removal and separation structure consists of three-stage separators. The dust-laden gas enters the separator from inlet 1 with an inlet velocity of about 8m / s. After the gas meets the baffle, larger dust and seeds will fall under the action of gravity, and smaller dust particles will enter the next-stage separator. The dust enters the cyclone separator, which can separate particles larger than 5-10μm (the purpose of setting the first-stage separator is to separate the powder particles according to the particle size, so that a reasonable inlet gas velocity can be set to just separate the dust of this particle size. If the gas velocity is too small, the separation efficiency is not high, and when the gas velocity is too high, eddy currents and back-mixing are easily generated). The dust is swirled up by the guide plate and enters the inverted cone part under the action of centrifugal force. As the radius becomes smaller and smaller, the rotation speed gradually increases, and the centrifugal force increases. When it reaches the bottom, the gas with high concentration sinks, and the gas with low concentration rises under the action of the vortex cover (when the airflow in the cyclone separator rotates inward, it will form lift at the bottom of the cone. If the lower seal is not good, the gas will flow into the container and the separation effect will be poor, so the vortex cover is designed). The gas with high concentration will enter the secondary inverted cone part in small quantities, where the gas will expand and slow down to release dust particles, and the gas with low concentration will rise and enter the next bag separator. The bag separator can To separate particles smaller than 5μm (the first two stages of dust removal filter larger particles to reduce the burden on the bag separator. Otherwise, the air is relatively humid, or dust and filter cloth, or dust and dust are bonded together. Therefore, the possibility of bag blockage can be reduced and the dust removal efficiency can be greatly improved). The bag is hung on a hook and positioned on the inclined plate at a certain distance from the air outlet for dust to fall. The dust adheres to the bag and will fall onto the inclined slide when it reaches a certain weight. It will be discharged from the opening of the inclined plate corresponding to the main shell, and the remaining gas will be discharged from the exhaust port on the top of the bag separator.

[0035] The first-stage dust separator first expands the dust particles, reduces their speed and changes their direction suddenly to collect dust. The gas velocity change effect is obvious at the baffle. After the gas meets the baffle, larger dust and seeds will fall under the action of gravity, and smaller dust particles will enter the next-stage separator, and the dust enters the secondary cyclone separator; the first-stage dust collector can separate particles with a particle size of more than 10μm, mainly including large dust particles and seeds.

[0036] The two-stage dust separator mainly utilizes the principle of centrifugal force; the diameter of the exhaust port is generally 0.5 to 0.6 times the outer diameter of the main shell, and the dust removal effect is better, while the diameter of the ash discharge port is generally 0.1 to 0.5 times the exhaust pipe diameter of the main shell. When the dust gas enters the second-stage dust separator from the first-stage dust separator, the dust gas will expand and reach the cylindrical turbulence on the exhaust port and offset it on the back. A small number of dust particles adhere to the wall and fall into the dust collecting container, and most of the dust gas will enter the guide plate. The guide plate plays the role of guiding and speeding up. Increasing the air inlet speed of the cyclone separator can improve the separation efficiency. The air inlet speed is generally 10 to 18 m / s. Therefore, the inlet speed must be changed to a reasonable speed to achieve better separation efficiency.

[0037] When the airflow in the cyclone separator rises with the inner vortex, lift is formed at the bottom of the cone. The design of the vortex cover is conducive to the formation of the rising vortex, which is beneficial to the separation efficiency. The dust is swirled up at the guide plate and enters the inverted cone part under the action of centrifugal force. The radius becomes smaller and smaller, and the rotation speed gradually increases. The centrifugal force increases, and when it reaches the bottom, the gas with high concentration sinks, and the gas with low concentration rises under the action of the vortex cover.

[0038] The bag separator of the three-stage dust collector can separate particles smaller than 5μm. The bag is hung on the hook of the inclined plate, and there is a certain distance between it and the air outlet for dust to fall. The dust sticks to the bag (the bag needs to be cleaned and replaced regularly). When it reaches a certain weight, it will fall onto the inclined plate and be discharged from the dust outlet of the three-stage dust collector. The remaining gas is discharged through the exhaust port.

[0039] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0040] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
