[0031] In order to solve the technical problem of low interception efficiency of existing paint mist interception equipment, the present technical solution proposes an interception mesh disk 100 for intercepting paint mist. The interception mesh disk 100 includes a plurality of meshes 110, and the plurality of meshes 110 are stacked. Each mesh 110 has a connecting disk 111 and a plurality of spokes 112 arranged on the connecting disk 111. The connecting disk 111 is used to connect to the motor transmission. The plurality of spokes 112 are distributed in a ring array, and the spokes 112 of every two adjacent meshes 110 are spirally staggered.
[0032] Compared with the prior art, in the technical solution of the utility model, the interception net disk 100 includes a plurality of stacked nets 110, each of which has a connecting disk 111 located in the center and a plurality of spokes 112 arranged on the connecting disk 111, the connecting disk 111 is used to connect with the output shaft of the motor to drive the entire net 110 to rotate around the central axis of the connecting disk 111, and the plurality of spokes 112 are distributed in a ring array along the axial direction of the connecting disk 111. In addition, the spokes 112 of every two adjacent nets 110 are staggered, and the spokes 112 of the plurality of nets 110 together form a spiral arrangement, such as Therefore, when intercepting paint mist, when the paint mist flows along the axial direction of the connecting disk 111, the paint mist will contact the spokes 112 on each mesh 110 in turn, thereby realizing multi-level interception of the paint mist and improving the interception efficiency. In addition, when the paint mist reaches a spoke 112, the paint mist that is not intercepted by the spoke 112 will also be dispersed by the spoke 112, and the dispersed paint mist can be intercepted by the spokes 112 on other meshes 110 on both sides of the spoke 112. This is equivalent to disturbing the paint mist, increasing the contact area and contact time between the paint mist and the interception mesh disk 100, thereby improving the interception efficiency.
[0033] Specifically, Figure 1~Figure 4In this embodiment, the interception net plate 100 is composed of a plurality of stacked net sheets 110, each of which can be fixed by bonding or the like, and the number of net sheets 110 can be set according to parameters such as the power of the motor and the concentration of the paint mist to be intercepted. According to simulation experiments, in this solution, the interception efficiency of setting 4 stacked net sheets 110 is optimal, and the load of the motor is not too large; each net sheet 110 includes a connecting disk 111, which is a circular plate-shaped structure, and the connecting disk 111 can be connected to the motor shaft of the motor by bolts or the like, through The motor drives the connecting disk 111 to rotate and then drives the entire mesh 110 to rotate to intercept the paint mist. In addition, a plurality of spokes 112 are arranged on the radial side wall of the connecting disk 111. The spokes 112 can be a strip plate structure extending radially. The plurality of spokes 112 are distributed in a ring array around the central axis of the connecting disk 111. When the connecting disk 111 rotates, each spoke 112 is driven to rotate, and the paint mist can be transported along the axial direction of the connecting disk 111. At this time, the spokes 112 can knock down the particles in the paint mist to achieve interception. In addition, in order to improve the interception efficiency, such as Figure 3 In the present embodiment, the spokes 112 of every two adjacent meshes 110 are staggered at a certain angle, so that after multiple meshes 110 are stacked, the spokes 112 of each mesh 110 together form a spiral arrangement, and the spokes 112 of adjacent meshes 110 are staggered to form gaps. In this way, during the rotation process, part of the paint mist is first knocked off by the spokes 112 of the end mesh 110, and then the other paint mist continues to be transported forward. At this time, the spokes 112 of the next adjacent mesh 110 continue to knock off part of the particles in the remaining paint mist. As the paint mist continues to be transported, the particles in the paint mist will contact the spokes 112 on each mesh 110 in turn, so that multi-level interception of the paint mist can be achieved, thereby improving the interception efficiency. In addition, during the interception process, the paint mist that is not intercepted by the spokes 112 will be broken up by the spokes 112 and dispersed along both sides of the axis of the connecting disk 111, and will continue to be intercepted and knocked down by the spokes 112 on other meshes 110 adjacent to the spokes 112. This is equivalent to disturbing the paint mist, increasing the contact time between the paint mist and the spokes 112, and is also conducive to further improving the interception efficiency.
[0034] Furthermore, the mesh 110 also has an outer ring 114, and the outer ring 114 is connected to each spoke 112. Figure 4In order to improve the structural strength of the interception net disk 100, in the present embodiment, an outer ring 114 structure is also provided on each mesh 110. The outer ring 114 is an annular plate structure. The outer ring 114 is coaxially arranged with the connecting disk 111, and one end of each spoke 112 away from the connecting disk 111 is connected to the outer ring 114. In this way, the support of the two ends of the spoke 112 by the outer ring 114 and the connecting disk 111 can reduce the deformation of the spoke 112 during rotation, thereby improving the strength of the mesh 110 and extending the service life of the interception net disk 100.
[0035] Furthermore, each connection disk 111 is provided with a plurality of first connection holes 113 , which are arranged at intervals around the axis of the connection disk 111 , and the first connection holes 113 of every two adjacent connection disks 111 are arranged in a one-to-one correspondence.
[0036] Furthermore, each outer ring 114 is provided with a plurality of second connection holes 115 , which are arranged at intervals around the axis of the outer ring 114 , and the second connection holes 115 of every two adjacent outer rings 114 are arranged in a one-to-one correspondence.
[0037] Specifically, Figure 2 and Figure 4 In the present embodiment, each connection disk 111 is further provided with a plurality of first connection holes 113, and the plurality of first connection holes 113 are distributed in a circular array around the central axis of the connection disk 111, and the positions of the first connection holes 113 of every two adjacent connection disks 111 correspond to each other, so that each mesh 110 can be assembled together by bolts and the first connection holes 113, which facilitates the assembly of the interception net disk 100 and also facilitates the interception net disk 100 to adjust the number of meshes 110 and the size specifications of the meshes 110 as needed; in addition, the provision of the plurality of first connection holes 113 is also conducive to increasing the number of connection points between each mesh 110, improving the connection strength between the meshes 110 and the overall structural strength of the interception net disk 100. Similarly, a plurality of second connection holes 115 may be provided on each outer ring 114, and the plurality of second connection holes 115 are distributed in a circular array around the central axis of the outer ring 114, and the positions of the second connection holes 115 of every two adjacent outer rings 114 correspond to each other, so that each mesh 110 can be assembled together through the cooperation of bolts and the second connection holes 115, which facilitates the assembly of the interception net disk 100 and also facilitates the interception net disk 100 to adjust the number of meshes 110 and the size specifications of the meshes 110 as needed; in addition, the provision of a plurality of second connection holes 115 is also conducive to increasing the number of connection points between each mesh 110, improving the connection strength between the meshes 110 and the overall structural strength of the interception net disk 100.
[0038] Furthermore, each spoke 112 is bent and extended. In order to reduce the load of the motor, in this embodiment, each spoke 112 on each mesh 110 is bent and extended, and the bending direction and bending amount of each spoke 112 are the same, and they are all bent and extended away from the rotation direction of the spoke 112. In this way, when intercepting paint mist, the intercepted particles and paint mist can be diverted along the bending direction of the spoke 112, so that the wind resistance of the interception net disk 100 during rotation can be reduced, thereby reducing the load of the motor.
[0039] Furthermore, the mesh 110 is made of stainless steel. The use of stainless steel can reduce the corrosion degree of VOC on the interception network disk 100, thereby extending the service life of the interception network disk 100.
[0040] The utility model also provides a network disk assembly 10, comprising:
[0041] The interception network disk 100 is the interception network disk 100 described above, and at least two interception network disks 100 are arranged at intervals along their own axis direction;
[0042] The gasket 200 connects at least two interception net disks 100, and the gasket 200 is used to be connected to the motor transmission to drive the interception net disk 100 to rotate.
[0043] In this solution, by setting at least two interception net disks 100 at intervals, the contact time and contact area between the paint mist and the interception device can be increased, the amount of intercepted paint mist can be increased, and the interception efficiency can be improved; in addition, in order to simplify the structure, a through hole corresponding to the position of the first connection hole 113 can be opened on the gasket 200, and the through hole and the first connection holes 113 on the two interception net disks 100 are connected as one by bolts, thereby realizing structural reuse and a simplified structure. In addition, another through hole can be opened in the center of the gasket 200 to be screwed to the motor, which also facilitates the assembly of the net disk assembly 10 and the motor. In addition, since the present interception net disk 100 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
[0044] The utility model also proposes a paint mist interception device, comprising:
[0045] The transmission shaft 20 is used for transmission connection with the motor, and the transmission shaft 20 is coaxially connected with the motor shaft of the motor through a connecting shaft or the like;
[0046] The mesh disk assembly 10 is provided with at least two groups, and the at least two groups of mesh disk assemblies 10 are arranged at intervals. The transmission shaft 20 is drivingly connected to the two mesh disk assemblies 10 to drive the mesh disk assemblies 10 to rotate, wherein the rotation directions of every two adjacent mesh disk assemblies 10 are opposite. The mesh disk assembly 10 and the transmission shaft 20 can be connected by a planetary gear reducer or a direct connection, and the mesh disk assembly 10 is driven to rotate by the rotation of the transmission shaft 20. In addition, in this solution, the rotation directions of the two adjacent mesh disk assemblies 10 are opposite. In this way, when the paint mist passes through one mesh disk assembly 10, the paint mist will rotate in a circumferential direction under the drive of the mesh disk assembly 10, and when the paint mist reaches another mesh disk assembly 10, since the rotation direction of the mesh disk assembly 10 is opposite, the rotation direction of the paint mist is opposite to the rotation direction of the mesh disk assembly 10, which will increase the impact of the paint mist on the mesh disk assembly 10, so that more particles are intercepted. In addition, in this process, the mesh disk assembly 10 also turbulents the paint mist, so that the paint mist flows irregularly between the two mesh disk assemblies 10, increasing the contact time between the paint mist and the mesh disk assembly 10, and further improving the interception effect. In addition, since the mesh disk assembly 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
[0047] Furthermore, the paint mist interception device also includes a collecting tray 30, and a collecting tray 30 is provided on one radial side of each mesh disk assembly 10. In order to facilitate the collection of intercepted substances, the paint mist interception device also includes a collecting tray 30, and the collecting tray 30 can be provided on one radial side of each mesh disk assembly 10, and an annular groove extending along the circumferential direction of the mesh disk assembly 10 can be provided on one end surface of the collecting tray 30 facing the mesh disk assembly 10, and the knocked-down particles can be thrown into the collecting tray 30 under the action of centrifugal force and discharged centrally through the discharge port on the collecting tray 30, which facilitates the collection of intercepted substances.
[0048] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention.
