Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to a pneumatic sweeper. Background Art

[0002] In industrial production, there are a large number of belt conveyors, plate feeders and other material conveying systems. The working surfaces of these conveying equipment are mostly cleaned with scraper cleaners or brushes. Among them, scraper cleaners cause great damage to the working surface of the equipment, and they are also prone to wear during use, and the cleaning effect becomes worse and worse in the later period. Due to the changeable nature of materials, the working surfaces of conveying equipment in some workplaces often use uneven surfaces such as pattern designs and plate overlap designs, making traditional scraper cleaners unable to adapt to the cleaning of the working surfaces of such equipment. Therefore, some equipment uses brush cleaners, but there are problems such as fast wear and unsatisfactory cleaning effects, which still cause the problem of material adhesion and spillage on the working surface, seriously affecting the on-site environment. Summary of the invention

[0003] The purpose of the present invention is to provide a pneumatic cleaner, which can efficiently remove material residues adhered to the working surfaces of various conveying equipment, is particularly suitable for cleaning various uneven working surfaces, has high working efficiency, and ensures a clean working environment.

[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] In the present invention, unless otherwise stated, directional words such as "near, between" and the like contained in a term merely represent the direction of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0025] See also Figure 1 The present invention provides a pneumatic sweeper, which includes an air intake component, a pressurizing component and a cleaning component connected in sequence, and the pressurizing component is configured to pressurize the gas obtained by the air intake component and spray the cleaning airflow toward the cleaning working surface through the cleaning component.

[0026] In this embodiment, preferably, the air extraction assembly comprises: a settling pipe 1 connected to the equipment to be cleaned, used to settle impurities and particulate matter in the airflow inside the equipment; a bell mouth 3 connected to the settling pipe 1, used to transition the settling pipe 1 and the subsequent pipeline; and a filter 2 arranged between the settling pipe 1 and the bell mouth 3, used to filter large-sized impurities. In this way, it can be ensured that large-sized impurities will not enter the air extraction pipe.

[0027] Furthermore, it is preferred that the settling pipe 1 is a large-diameter pipe and the cross-sectional wind speed is set below 5 m / s. In this way, most of the impurities and particulate matter in the airflow can be settled, and relatively clean airflow enters the subsequent air intake pipeline.

[0028] In this embodiment, preferably, the above-mentioned boosting component includes a suction pipe 4, a control valve 5 and a boosting fan 6 connected in sequence, the suction pipe 4 is connected to the bell mouth 3, and the boosting fan 6 is connected to the cleaning component to boost the airflow sucked by the suction pipe 4 and input it into the cleaning component.

[0029] Furthermore, in order to enable the booster fan 6 to be configured with different specifications according to different cleaning pressure and air volume parameter requirements, while ensuring the cleaning effect and taking into account economy, it is preferred that the booster fan 6 be detachably installed in the booster assembly. Such a design greatly facilitates replacement.

[0030] In this embodiment, preferably, the above-mentioned cleaning component includes a high-pressure air duct 7 and a cleaning spray pipe 8, one end of the high-pressure air duct 7 is connected to the booster fan 6, and the other end extends and is connected to the cleaning spray pipe 8. The cleaning spray pipe 8 is configured to be able to spray a cleaning airflow toward the cleaning working surface in the equipment to be cleaned.

[0031] Specifically, one end of the cleaning spray pipe 8 connected to the high-pressure air duct 7 is an open end, and the other end is a closed end, and the area close to the closed end forms a cleaning spray working section, and a plurality of spray holes are opened on the cleaning spray working section, and the spray holes are arranged to spray the cleaning airflow toward the cleaning working surface.

[0032] In order to further expand the coverage area of ​​the blowing holes, preferably, a plurality of blowing holes are arranged in an array.

[0033] The airflow in the tube is ejected at high speed through the small holes to form a jet air curtain, which can clean the working surface at high speed. However, since the airflow ejected from the small holes is a conical diffused airflow, it is necessary to adjust the small hole design spacing and the cleaning working spacing so that the conical airflow curtains ejected from each small hole can overlap with each other to avoid cleaning dead corners.

[0034] In addition, in this embodiment, in order to conveniently control the impact force of the airflow ejected from the small hole, preferably, a flow valve capable of controlling the airflow size is provided between the cleaning spray pipe 8 and the high-pressure air pipe 7 .

[0035] In actual use, the booster fan 6 is turned on, and the air flow inside the equipment passes through the settling pipe 1, the filter 2, the bell mouth 3, the air suction pipe 4, the control valve 5, the booster fan 6, the high-pressure air pipe 7 and the cleaning spray pipe 8 in sequence to clean the working surface. After cleaning, the air flow returns to the inside of the equipment. The air flow is taken out from the inside of the equipment and finally returns to the inside of the equipment. There is no external exhaust flow, which is more environmentally friendly.

[0036] Through the above technical solution, the pneumatic cleaner uses airflow to clean the working surface of the conveying equipment, without wear and tear, and does not damage the equipment. At the same time, the cleaning work uses the airflow inside the equipment to extract and pressurize, and then return to the inside of the equipment, and the airflow circulates for cleaning, without exhaust gas discharge. In addition, the cleaning medium is airflow, which does not affect the operation of the equipment, and there is no dead angle in the cleaning, which can adapt to the cleaning of various special-shaped working surfaces. In addition, the cleaning spray pipe does not contact the working surface of the equipment, and there is no wear, which avoids the problem of reduced cleaning efficiency due to wear of traditional cleaners.

[0037] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
