Description

Technical Field

[0001] The utility model relates to the field of construction sites, in particular to a dust removal operation platform for construction sites. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] When workers cut tiles or aerated concrete blocks at construction sites, dust is generated. Workers usually do not take protective measures, and dust is dispersed in the air at will. Dust floating in the air causes air pollution, and people who are in this environment for a long time are more likely to suffer from pneumoconiosis. Simply wearing a mask can only solve the breathing problem of the operator, but the dust floating in the air will also affect the surrounding people; and the dust floating will also affect the work efficiency of workers;

[0004] The inventors found that in the prior art, in order to control dust on construction sites, some construction sites have set up dust removal rooms, but there are problems of large floor space and high investment; some construction sites also use the method of installing transparent dust hoods, which requires workers to work in the dust hoods and cannot work anytime and anywhere, affecting the work efficiency of workers. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a dust removal operation platform for construction sites, which can form a negative pressure area on the work surface to adsorb dust, thereby facilitating dust control on the construction site.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] A dust removal operation platform for construction sites includes a work surface, which is a hollow work surface supported by legs, a first filter screen is arranged downwardly at an angle below the work surface, the first filter screen has a plurality of meshes, and the diameter of the meshes of the first filter screen is smaller than the diameter of some dust particles on the construction site, a powder storage bucket is arranged on the bottom side of the first filter screen, and the side of the first filter screen away from the work surface is connected to an exhaust fan.

[0008] As described above, the operating platform has a hollow work surface. When working, the exhaust fan is started, and the wind generated passes through the first filter and flows downward, forming a negative pressure area at the work surface, and adsorbing the dust generated at the work surface to the bottom of the work surface. Due to the setting of the mesh size of the first filter, the construction site dust particles larger than the mesh diameter of the first filter fall into the powder storage bucket along the downward inclined first filter under the action of gravity, thereby effectively treating the construction site dust.

[0009] In the dust removal operation platform for construction sites as described above, the legs are located on both sides of the lower surface of the work surface, or the legs are located around the lower surface of the work surface. At this time, the legs wrap around the first filter and other structures, which is helpful to prevent dust from spilling out.

[0010] As described above, in order to make full use of the space below the work surface, the bottom of the first filter is arranged higher than the bottom of the leg, one side of the powder storage barrel is connected to the adjacent leg, and the other side of the powder storage barrel is connected to the bottom of the first filter.

[0011] As described above, in a dust removal operation platform for construction sites, when the legs have a set length, the legs on one side of the work surface form a side wall of the powder storage barrel, and there is no need to separately set up a side wall of the powder storage barrel, which is beneficial to saving space under the work surface.

[0012] In the dust removal operation platform for construction sites as described above, a drawer is arranged in the powder storage barrel, and the collected dust can be processed uniformly by pulling out the drawer.

[0013] In the dust removal operation platform for construction sites as described above, the top side of the first filter screen is detachably connected to the lower surface of the work surface, so as to facilitate the cleaning of the first filter screen.

[0014] As described above, for a dust removal operation platform for construction sites, in another embodiment, the top side of the first filter screen can be detachably mounted on the top of the support leg on one side of the work surface.

[0015] A dust removal operation platform for construction sites as described above, wherein the work surface is detachably connected to the legs;

[0016] The top side of the first filter is provided with an extension portion, which is located between the work surface and the legs. Thus, after the connection between the work surface and the legs is removed, the connection between the first filter and the legs or the work surface is also loosened, so that the first filter can be easily cleaned.

[0017] In the dust removal operation platform for construction sites as described above, the exhaust fan is connected to the peripheral side of the first filter screen through a trumpet-shaped air duct, and the shape of one end of the trumpet-shaped air duct used for connecting to the first filter screen is adapted to the shape of the first filter screen.

[0018] In the dust removal operation platform for construction sites as described above, the exhaust fan is fixed to the supporting legs on one side of the work surface to ensure that the exhaust fan is stably supported.

[0019] The beneficial effects of the above utility model are as follows:

[0020] 1) The work surface in the utility model is a hollow surface. When working, the exhaust fan is started, and the wind generated passes through the first filter and flows downward, which can form a negative pressure area on the work surface, and absorb the dust generated on the work surface to the bottom of the work surface. Due to the setting of the mesh size of the first filter, the construction site dust particles larger than the mesh diameter of the first filter fall into the powder storage barrel along the first filter inclined downward under the action of gravity, thereby effectively centrally treating the construction site dust and preventing the floating dust from affecting the work production efficiency.

[0021] 2) The utility model can efficiently collect and centrally process the dust generated by cutting on the construction site through the setting of the overall structure. There is no need to set up a dust removal room, the dust removal cost is controlled, and there is no need to install a dust hood. There is no need to work in a specific working environment. Cutting only needs to be done on the operating platform, which ensures the work efficiency of the workers and is beneficial to ensuring the health of the workers.

[0022] 3) The first filter screen structure in the utility model is reasonably arranged. By selecting a suitable mesh, it can not only ensure the normal flow of airflow and the negative pressure effect on the work surface, but also effectively prevent dust from falling into the powder storage barrel.

[0023] 4) The utility model makes full use of the space below the work surface, organically integrates all structures, and arranges the structures reasonably to ensure stable support for the exhaust fan and the powder storage barrel.

[0024] 5) In the utility model, the work surface is detachably connected to the supporting legs. After the work surface is removed from the supporting legs, the first filter screen can be easily cleaned to ensure subsequent normal use. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0031] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or their combinations;

[0032] As introduced in the background technology, in the prior art, there is a problem of large dust in the cutting process at the construction site. In order to solve the above technical problem, the utility model proposes a dust removal operation platform for the construction site.

[0033] In a typical implementation of the present invention, reference is made to Figure 1 As shown, a dust removal operation platform for construction sites includes a work surface 1, which is a hollow surface and is supported by legs 2. A first filter screen 3 is arranged obliquely downward below the work surface 1. The first filter screen 3 has a plurality of meshes. The diameter of the mesh of the first filter screen is smaller than the diameter of some dust particles on the construction site. A powder storage bucket is arranged on the bottom side of the first filter screen, and the side of the first filter screen away from the work surface is connected to the exhaust fan.

[0034] refer to Figure 2 As shown, the work surface 1 is a rectangular work surface, and multiple grids are arranged on the work surface. Specifically, a hollow steel plate support can be used, and cutting and other work can be performed on the work surface;

[0035] In some examples, the legs 2 are located on opposite sides of the lower surface of the work surface, and the length of the legs 2 can be the same as the length of the work surface 1, or there are only four legs, which are located at the four corners of the work surface 1; in other examples, the legs 2 are four side walls, and the four side walls are located on the peripheral side of the lower surface of the work surface, and two adjacent legs can be connected by bolts. At this time, the legs 2 wrap around the first filter screen and other structures, which is beneficial to prevent dust from spilling out.

[0036] Regarding the first filter 3, the first filter 3 has multiple meshes. Since the diameter of the dust particles generated by cutting tiles or concrete blocks on the construction site is usually greater than 20μm, the diameter of the first filter mesh should be less than or equal to 20μm. The first filter 3 is made of stainless steel wire mesh, which is not easy to deform. Specifically, 800 mesh or 1000 mesh sieves can be selected (other mesh sizes can also be used). In this way, most of the dust particles on the construction site can be filtered out. Even if some of the dust particles on the construction site enter the exhaust fan, it will not affect the normal operation of the exhaust fan.

[0037] It is easy to understand that in order to make full use of the space below the work surface, the bottom of the first filter screen 3 is arranged higher than the bottom of the leg 2, the top of the powder storage barrel 6 is arranged to be open, the powder storage barrel has a set width, one side of the powder storage barrel 6 is connected to the adjacent leg, and the other side of the powder storage barrel 6 is connected to the bottom of the first filter screen, and the bottom of the powder storage barrel 6 can be located in the same plane as the bottom of the exhaust fan.

[0038] In this embodiment, when the support leg 2 has a set length, the support leg on one side of the work surface 1 forms a side wall of the powder storage barrel 6, and there is no need to set up a side wall of the powder storage barrel separately, which is beneficial to saving space under the work surface.

[0039] In this embodiment, a drawer is arranged in the powder storage barrel 6. Under the action of external force, the drawer can be pulled out relative to the powder storage barrel, and the collected dust can be processed uniformly. After processing, the drawer is sent into the powder storage barrel for subsequent work. Rubber is arranged on the surrounding side of the drawer to improve air tightness during the working process.

[0040] It should be noted that, in some examples, the top side of the first filter 3 is detachably connected to the lower surface of the work surface, and the bottom side of the first filter is detachably connected to one side of the powder storage barrel, such as by bolts and nuts, to facilitate cleaning of the first filter 3.

[0041] In another example, the top side of the first filter 3 can be detachably mounted on the top of a leg on one side of the work surface 1, and can be specifically fixed to the top of the inner side of the leg by bolts or nuts.

[0042] In this embodiment, the work surface 1 is detachably connected to the support leg 2; an extension portion is provided on the top side of the first filter screen 3, and the extension portion may specifically be in a rectangular shape. The extension portion is located between the work surface 1 and the support leg 2. The bolts pass through the work surface and are connected to the extension portion of the first filter screen and the support leg. In this way, after the connection between the work surface and the support leg is removed, the connection between the first filter screen 3 and the support leg or the work surface is also loosened, so that the first filter screen 3 is easily cleaned.

[0043] In this embodiment, the exhaust fan 5 is connected to the peripheral side of the first filter screen 3 through the trumpet-shaped air duct 4, and the exhaust fan 5 and the trumpet-shaped air duct 4 are detachably connected. The shape of one end of the trumpet-shaped air duct 4 used for connecting with the first filter screen 3 is adapted to the shape of the first filter screen. A protrusion is provided on the peripheral side of the trumpet-shaped air duct, and a rubber pad is provided at the protrusion to improve the sealing performance. The trumpet-shaped air duct 4 and the peripheral side of the first filter screen 3 are detachably connected by bolts and nuts, which further facilitates the cleaning of the first filter screen.

[0044] In order to further prevent dust from entering the exhaust fan 5, a second filter is arranged between the exhaust fan 5 and the trumpet-shaped air duct 4, and the diameter of the mesh of the second filter is less than or equal to the diameter of the mesh of the first filter.

[0045] In addition, the exhaust fan 5 is fixed to a support leg on one side of the work surface, and can be specifically fixed to the support leg on one side by bolts and nuts to ensure that the exhaust fan is stably supported.

[0046] The operating platform provided in this embodiment has a hollow work surface 1. When working, the exhaust fan 5 is started, and the generated wind passes through the first filter screen 3 and flows downward, which can form a negative pressure area on the work surface, and absorb the dust generated on the work surface to the bottom of the work surface. Due to the setting of the mesh size of the first filter screen, even if some dust particles on the construction site enter the air duct, most of the dust particles on the construction site fall into the powder storage barrel 6 along the downward inclined first filter screen 3 under the action of gravity, thereby effectively processing the dust on the construction site. After the set working time, the dust in the drawer is poured out by pulling out the drawer for unified processing.

[0047] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
