Description
Technical Field
[0001] This utility model relates to the field of dust control technology in coal mine return air roadways, and in particular to a portable and detachable dust collection device. Background Technology
[0002] In fully mechanized mining faces, coal dust is severe in the return airway, and it easily accumulates. Currently used dust collection devices use a single integrated structure for the dust collection frame and net, which is complex and heavy, making installation and movement of the net inconvenient and resulting in less than ideal dust collection efficiency. The dust collection net needs to be replaced when it is damaged or reaches its service life. However, replacing the net usually involves replacing the entire net and frame, which is heavy, difficult, and costly. Furthermore, during operations in the return airway, increased pressure can cause the inner walls of the return airway to compress the dust collection frame, leading to deformation or damage and affecting dust collection efficiency. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a portable and detachable dust collection device. The technical solution of this utility model is as follows: A portable and detachable dust collection device includes a dust collection frame, comprising a main crossbar, multiple connecting tees, elastic connectors, and multiple vertical rods; both ends of the main crossbar are connected to the elastic connectors via the connecting tees, and the other end of the elastic connector is connected to one end of the vertical rod via the connecting tees; the vertical rods extend downward in a vertical direction; the dust collection frame is installed on a suspended beam at the top of a return airway via a connecting structure; multiple dust collection nets have their edges detachably connected to adjacent vertical rods via magnetic assemblies.
[0004] Optionally, the elastic connector includes a connecting spring, the two ends of which are respectively connected to the adjacent connecting tee, and a plurality of connecting springs are evenly distributed at both ends of the main crossbar.
[0005] Optionally, the vertical rod is configured to be flat.
[0006] Optionally, the magnetic assembly includes a plurality of magnets, which are distributed at the edge of the dust collection net and magnetically connected to adjacent vertical bars.
[0007] Optionally, each of the connecting tees includes a first interface, a second interface, and a third interface. The two ends of the main crossbar are respectively connected to one end of the connecting spring through the first interface of the connecting te, the other end of the connecting spring is connected to the second interface of the connecting te, and one end of the vertical rod is connected to the third interface of the connecting te.
[0008] Optionally, the elastic connector further includes multiple connection interfaces, one end of which is fixedly connected to the end of the connecting spring, and the other end of which is threadedly connected to the first and second interfaces of the adjacent connecting tee, respectively.
[0009] Optionally, the connection structure includes multiple hooks, one end of which is spaced apart and connected to the top of the main crossbar, the top of multiple connecting tees, and the second interface of two connecting tees located at both ends of the dust collection frame, and the other end of which is hung on the suspension beam at the top of the return airway.
[0010] Optionally, the two ends of the main crossbar are connected to the first interface of the connecting tee by threaded connection, and the vertical bar is connected to the third interface of the connecting tee by threaded connection.
[0011] All of the above optional technical solutions can be combined arbitrarily, and this utility model does not provide a detailed description of the structure after each combination.
[0012] The beneficial effects of this utility model through the above solution are as follows: By setting up a main horizontal bar, multiple tee connectors, flexible connectors, and multiple vertical bars, and connecting both ends of the main horizontal bar to the flexible connectors via tee connectors, and connecting the other end of the flexible connector to one end of the vertical bar via a tee connector, a dust collection frame for fixing the dust collection net is formed. The dust collection frame is installed on the overhead beam in the return air tunnel through a connecting structure, and the edge of the dust collection net is detachably connected to the adjacent vertical bar via magnetic components, thus setting the dust collection frame and dust collection net as a separate structure. When the dust collection net needs to be replaced... When installing the dust collector, the magnetic attachment can be removed to easily disassemble the dust collector, avoiding the need for complete replacement and reducing replacement costs and difficulty. Furthermore, when the pressure in the return air duct changes, the two inner side walls of the return air duct may compress the ends of the dust collector frame. However, by installing elastic connectors at both ends of the main crossbar, compression can occur when the dust collector frame is compressed by the two inner side walls of the return air duct, protecting the main crossbar from compressive force. This prevents deformation or damage to the main crossbar and reduces the impact of the dust collector frame's stress on the dust collection effect.
[0013] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0017] like Figures 1 to 5 As shown, this utility model provides a portable and detachable dust collection device, including a dust collection frame 1, comprising a main crossbar 101, multiple connecting tees 102, elastic connectors 3, and multiple vertical rods 103; both ends of the main crossbar 101 are connected to the elastic connectors 3 via connecting tees 102, and the other end of the elastic connector 3 is connected to one end of the vertical rod 103 via a connecting tee 102, and the vertical rod 103 extends downward in the vertical direction; the dust collection frame 1 is installed on the cantilever beam at the top of the return airway via a connecting structure 2; multiple dust collection nets 4, the edges of which are detachably connected to adjacent vertical rods 103 via magnetic assemblies 5.
[0018] Specifically, the shape of the main crossbar 101 is not limited in this application; it can be a square tube or a round tube. The number of connecting tees 102, elastic connectors 3, vertical rods 103, and dust traps 4 is not limited in this application. In this embodiment, there are four connecting tees 102, two elastic connectors 3, four vertical rods 103, and three dust traps 4. The four connecting tees 102 are evenly arranged on both sides of the main crossbar 101. The elastic connectors 3 are connected between the two connecting tees 102 on the same side. The three dust traps 4 are detachably connected to the two vertical rods 103 and the elastic connectors 3 on one side of the main crossbar 101, the two vertical rods 103 and the main crossbar 101, and the two vertical rods 103 and the elastic connectors 3 on the other side of the main crossbar 101.
[0019] It should be noted that, in this embodiment, if the connection position of the dust collection net 4 is located between the two vertical rods 103 and the elastic connector 3, the left edge 401 and right edge 402 of the dust collection net 4 are detachably connected to the two adjacent vertical rods 103, and the upper edge 403 of the dust collection net 4 is not fixed; if the connection position of the dust collection net 4 is located between the two vertical rods 103 and the main horizontal rod 101, the left edge 401 and right edge 402 of the dust collection net 4 are detachably connected to the two adjacent vertical rods 103, and the upper edge 403 of the dust collection net 4 is detachably connected to the main horizontal rod 101 through the magnetic suction assembly 5.
[0020] By setting up a dust collection frame 1 and a dust collection net 4, the dust collection frame 1 and the dust collection net 4 are set as separate structures. When it is necessary to replace the dust collection net 4, the dust collection net 4 can be easily disassembled by removing the magnetic suction component 5, avoiding the need for overall replacement and reducing replacement costs and difficulties. Furthermore, when the pressure in the return air roadway changes, the two inner side walls of the return air roadway may squeeze the two ends of the dust collection frame 1. However, by setting elastic connectors 3 at both ends of the main crossbar 101, compression can occur when the two inner side walls of the return air roadway squeeze the dust collection frame 1, protecting the main crossbar 101 from the squeezing force. This can prevent the main crossbar 101 from deforming or being damaged, and reduce the impact of the force on the dust collection frame 1 on the dust collection effect.
[0021] Optionally, the elastic connector 3 includes a connecting spring 301, the two ends of which are respectively connected to the adjacent connecting tee 102, and multiple connecting springs 301 are evenly distributed at both ends of the main crossbar 101.
[0022] By setting the elastic connector 3 as a connecting spring 301, when the inner walls of the return air tunnel press against the dust collection frame 1, the connecting spring 301 is compressed, which reduces the distance between the connecting tee 102 connected to both ends of the connecting spring 301, and in turn reduces the distance between the two vertical bars 103. This avoids the inner walls of the return air tunnel directly pressing against the main horizontal bar 101, and avoids deformation or damage to the main horizontal bar 101. When the pressing force applied by the inner walls of the return air tunnel disappears, the connecting spring 301 can automatically reset, reducing the impact on the dust collection effect.
[0023] Alternatively, the vertical rod 103 can be configured to be flat.
[0024] By making the vertical rod 103 flat, the magnetic attraction area between the side of the dust collection net 4 and the vertical rod 103 can be increased, and the contact area between the magnetic attraction component 5 and the vertical rod 103 can be increased, thereby ensuring the magnetic attraction stability between the two sides of the dust collection net 4 and the two adjacent vertical rods 103.
[0025] Optionally, the magnetic assembly 5 includes a plurality of magnets 501, which are distributed at the edge of the dust collection net 4 and magnetically connected to the adjacent vertical rods 103.
[0026] By setting the magnetic component 5 as a magnet 501, a magnetic connection between the edge of the dust collection net 4 and the vertical rod 103 is achieved, which is easy to disassemble and reduces the difficulty of replacing the dust collection net 4.
[0027] Optionally, each connecting tee 102 includes a first interface 1021, a second interface 1022, and a third interface 1023. The two ends of the main crossbar 101 are respectively connected to one end of the connecting spring 301 through the first interface 1021 of the connecting tee 102, the other end of the connecting spring 301 is connected to the second interface 1022 of the connecting tee 102, and one end of the vertical bar 103 is connected to the third interface 1023 of the connecting tee 102.
[0028] By setting the first interface 1021, the second interface 1022 and the third interface 1023, the main crossbar 101, the connecting spring 301 and the vertical bar 103 can all be connected to the corresponding interface, which is beneficial to the overall stability of the dust collection frame 1.
[0029] Optionally, the elastic connector 3 also includes multiple connection interfaces 302. One end of the multiple connection interfaces 302 is fixedly connected to the end of the connecting spring 301, and the other end of the multiple connection interfaces 302 is threadedly connected to the first interface 1021 and the second interface 1022 of the adjacent connecting tee 102, respectively.
[0030] Specifically, this application does not limit the number of connection interfaces 302. In this embodiment, the number of connection interfaces 302 is two.
[0031] By setting a connection interface 302, one end of the connection interface 302 is connected to the connection spring 301, and the other end of the connection interface 302 is threadedly connected to the connection tee 102, the connection spring 301 can be detached, making it easy to replace the connection spring 301.
[0032] Optionally, the connection structure 2 includes multiple hooks 201. One end of the multiple hooks 201 is connected at intervals to the top of the main crossbar 101, the top of multiple connecting tees 102, and the second interface 1022 of two connecting tees 102 located at both ends of the dust collection frame 1. The other end of the hooks 201 is hung on the suspension beam at the top of the return airway.
[0033] Specifically, this application does not limit the number of hooks 201, which can be determined according to the actual on-site operation. In this embodiment, the hooks 201 are connected to the dust collection frame 1 in a fixed manner, which can ensure that the dust collection frame 1 is stably hung on the suspended beam at the top of the return air roadway.
[0034] By setting up hook 201, the dust collection frame 1 is hung on the overhead beam at the top of the return air roadway. If the dust collection frame 1 needs to be replaced, it can be easily removed and replaced, reducing the difficulty of operation and saving operation time.
[0035] Optionally, the two ends of the main crossbar 101 are connected to the first interface 1021 of the connecting tee 102 by means of threaded connection, and the vertical bar 103 is connected to the third interface 1023 of the connecting tee 102 by means of threaded connection.
[0036] By setting the dust collection frame 1 as a threaded, detachable structure, it is not only convenient to transport and install the dust collection frame 1, but also to reduce the difficulty and time of replacement and maintenance.
[0037] In summary, by setting up the dust collection frame 1 and the dust collection net 4, the dust collection net 4 can be easily replaced, reducing the difficulty and time of operation. When the pressure in the return air roadway changes, by setting connecting springs 301 at both ends of the main crossbar 101, the connecting springs 301 can be compressed when the dust collection frame 1 is squeezed by the inner side walls of the return air roadway, protecting the main crossbar 101 from the squeezing force, thereby preventing the main crossbar 101 from deforming or being damaged. By setting the connecting structure 2 as a hook 201, the dust collection frame 1 can be hung on the suspension beam at the top of the return air roadway. If the dust collection frame 1 needs to be replaced, it can be easily removed and replaced, reducing the difficulty of operation and saving operation time.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
