Through the above technical solution, based on the existing exhaust gas discharge device for electrostatic spraying, a spray assembly and a filter are provided in the exhaust gas concentration box, so as to improve the exhaust gas purification effect of the exhaust gas discharge device for electrostatic spraying.

[0004] Regarding the above-mentioned related content, the following technical defects exist: the pipe body of the connecting pipe connected to the exhaust gas emission device for electrostatic spraying is relatively large, which also causes the surface of the pipe body of the connecting pipe to be deformed due to its own gravity when the connecting pipe is connected to the exhaust gas emission device for electrostatic spraying for a long time, resulting in the connecting pipe being unable to continue to guide and discharge the exhaust gas generated by the electrostatic spraying work. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the pipe body of the connecting pipe connected to the exhaust gas emission device for electrostatic spraying is relatively large, which also leads to the deformation of the pipe body surface of the connecting pipe due to its own gravity when the connecting pipe is connected to the exhaust gas emission device for electrostatic spraying for a long time, resulting in the inability of the connecting pipe to continue to guide and discharge the exhaust gas generated by the electrostatic spraying work.

[0006] In order to solve the above technical problems, the utility model provides an exhaust gas emission device for electrostatic spraying, comprising: an exhaust gas emission device body, the upper surface of the exhaust gas emission device body is fixedly connected with a connecting pipeline, and a supporting device is provided at one end of the circular arc surface of the connecting pipeline, and the supporting device comprises a contact plate and a fixing rod, the contact plate is slidably connected to the connecting pipeline, the fixing rod is fixedly connected with a connecting rod at one end close to the contact plate, the inner wall of the fixing rod is slidably connected to the limiting rod, the connecting rod is fixedly connected with a fixing block at one end away from the fixing rod, the inner wall of the fixing block is fixedly connected with an adjusting rod, the circular arc surface of the adjusting rod is rotatably connected with an arc plate, the inner wall size of the arc plate is adapted to the circular arc surface size of the fixing rod, a limiting hole is provided at one end of the arc plate, and a connecting sleeve is slidably connected to the end of the arc plate away from the fixing block, and the connecting sleeve is fixedly connected to the contact plate on the side away from the arc plate.

[0007] The effect achieved by the above-mentioned components is: when workers are performing electrostatic spraying, the exhaust gas generated during electrostatic spraying can be discharged through the exhaust gas discharge device body through the connecting pipe. Because the pipe body of the connecting pipe is larger, this also causes the connecting pipe to be connected to the exhaust gas discharge device body for a long time, which will cause the pipe body surface of the connecting pipe to be deformed due to its own gravity, causing the connecting pipe to be unable to continue to guide and discharge the exhaust gas generated by the electrostatic spraying work. Workers can support the surface of the connecting pipe through the supporting device, thereby effectively reducing the influence of the connecting pipe on itself and avoiding deformation of the connecting pipe.

[0008] Preferably, two ends of the spring are fixedly connected to the limiting rod and the fixing rod respectively.

[0009] The effect achieved by the above components is that when the limit rod is connected to the arc plate through the limit hole, the spring installed on the limit rod can improve the connection stability between the limit rod and the arc plate and prevent the limit rod from slipping out of the limit hole.

[0010] Preferably, one end of the limiting rod away from the spring is fixedly connected to a guide block, and the guide block is funnel-shaped.

[0013] The effect achieved by the above components is that when the contact plate is connected to the connecting pipeline, the anti-slip groove provided on the contact plate can improve the stability of the connection between the contact plate and the connecting pipeline.

[0014] Preferably, the arc surface of the fixing rod is provided with an auxiliary device, and the auxiliary device includes a limiting cylinder, which is fixedly connected to the fixing rod, and the arc surface of the limiting cylinder is clamped with an elastic plate, and both ends of the arc surface of the elastic plate are fixedly connected with connecting blocks, and the inner walls of the two connecting blocks are slidably penetrated by the same connecting rod, and one end of the arc surface of the connecting rod is threadedly connected with a threaded ring, the arc surface of the elastic plate is rotatably connected to three support rods, and the surface of the support rod is rotatably connected to a base plate.

[0015] The effect achieved by the above-mentioned components is: in order to improve the portability of the supporting device, the design of the entire supporting device is relatively light, which also results in that when the fixing rod comes into contact with the flat ground, the supporting effect of the fixing rod on the entire supporting device will be poor when the fixing rod is in use, and then the connecting pipeline cannot be supported by the supporting device. At this time, an auxiliary device can be used to increase the connection stability between the fixing rod and the uneven ground, thereby further improving the supporting effect of the supporting device on the connecting pipeline.

[0018] Preferably, a protection pad is fixedly connected to one side of the threaded ring close to the connecting block, and the cross-section of the protection pad is circular.

[0019] The effect achieved by the above components is: when the threaded ring rotates on the connecting rod and connects with the connecting block, the protective pad installed on the threaded ring can prevent the threaded ring and the connecting block from contacting each other, thereby effectively preventing the two from contacting each other and causing wear.

[0020] Compared with the related art, the exhaust gas discharge device for electrostatic spraying provided by the utility model has the following beneficial effects:

[0021] The utility model provides an exhaust gas emission device for electrostatic spraying. By arranging a supporting device, when a connecting pipeline is connected to the exhaust gas emission device, the surface of the connecting pipeline can be supported by the supporting device, thereby effectively avoiding the situation in which the surface of the pipe body is affected by its own gravity when the connecting pipeline is connected to the exhaust gas emission device for a long time, resulting in deformation. The supporting device can effectively increase the service life of the connecting pipeline.

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0034] See also Figures 1 to 8 An embodiment of the utility model provides an exhaust gas emission device for electrostatic spraying, comprising: an exhaust gas emission device body 1, the upper surface of the exhaust gas emission device body 1 is fixedly connected with a connecting pipe 4, a supporting device 2 is provided at one end of the arc surface of the connecting pipe 4, and an auxiliary device 3 is provided on the arc surface of the fixing rod 201.

[0035] In the embodiments of the present invention, please refer to Figures 2 to 5The supporting device 2 includes a contact plate 208 and a fixed rod 201, the contact plate 208 is slidably connected to the connecting pipe 4, the end of the fixed rod 201 close to the contact plate 208 is fixedly connected to the connecting rod 202, the inner wall of the fixed rod 201 is slidably connected to the limiting rod 209, the end of the connecting rod 202 away from the fixed rod 201 is fixedly connected to the fixing block 203, the inner wall of the fixing block 203 is fixedly connected to the adjusting rod 204, the arc surface of the adjusting rod 204 is rotatably connected to the arc plate 205, the inner wall size of the arc plate 205 is adapted to the arc surface size of the fixed rod 201, and a limiting hole 2 is provided at one end of the arc plate 205 06. The end of the arc plate 205 away from the fixed block 203 is slidably connected with a connecting sleeve 207. The side of the connecting sleeve 207 away from the arc plate 205 is fixedly connected to the contact plate 208. When the worker is performing electrostatic spraying, the exhaust gas generated by the electrostatic spraying can be discharged through the exhaust gas discharge device body 1 through the connecting pipe 4. Because the pipe body of the connecting pipe 4 is large, this also causes the connecting pipe 4 to be connected to the exhaust gas discharge device body 1 for a long time. The surface of the pipe body of the connecting pipe 4 will be deformed due to the influence of its own gravity, resulting in the inability of the connecting pipe 4 to continue to discharge the exhaust gas generated by the electrostatic spraying work. To guide the discharge, the worker can support the surface of the connecting pipe 4 through the supporting device 2, thereby effectively reducing the influence of the connecting pipe 4 on itself and avoiding deformation of the connecting pipe 4. The two ends of the spring 210 are respectively fixedly connected to the limit rod 209 and the fixing rod 201. When the limit rod 209 is connected to the arc plate 205 through the limit hole 206, the spring 210 installed on the limit rod 209 can improve the connection stability of the limit rod 209 and the arc plate 205, avoiding the limit rod 209 from slipping out of the limit hole 206. The end of the limit rod 209 away from the spring 210 is fixedly connected with a guide block 211, the guide block 211 is funnel-shaped. When the limit rod 209 is connected to the inner wall of the fixed rod 201, the guide block 211 installed on the limit rod 209 can increase the connection speed between the limit rod 209 and the fixed rod 201, thereby improving the connection efficiency of the two by increasing the connection speed. The inner wall of the contact plate 208 is provided with a plurality of anti-skid grooves 212, and the plurality of anti-skid grooves 212 are evenly distributed on the contact plate 208. When the contact plate 208 is connected to the connecting pipe 4, the anti-skid grooves 212 provided on the contact plate 208 can improve the stability of the connection between the contact plate 208 and the connecting pipe 4.

[0036] In the embodiments of the present invention, please refer to Figures 6 to 8The auxiliary device 3 includes a limiting cylinder 31, which is fixedly connected to the fixing rod 201, and the arc surface of the limiting cylinder 31 is clamped with an elastic plate 32, and both ends of the arc surface of the elastic plate 32 are fixedly connected with connecting blocks 33, and the inner walls of the two connecting blocks 33 are slidably penetrated by the same connecting rod 34, and one end of the arc surface of the connecting rod 34 is threadedly connected with a threaded ring 35, and the arc surface of the elastic plate 32 is rotatably connected to three support rods 36, and the surface of the support rod 36 is rotatably connected to the bottom plate 37. In order to improve the portability of the support device 2, the design of the entire support device 2 is relatively light, which also causes the fixing rod 201 to come into contact with the flat ground, which will cause the fixing rod 201 to have a poor supporting effect on the entire support device 2 when in use, thereby making it impossible to support the connecting pipe 4 through the support device 2. At this time, the auxiliary device 3 can be used The connection stability between the fixing rod 201 and the uneven ground is increased, thereby further improving the supporting effect of the supporting device 2 on the connecting pipeline 4. A plurality of protrusions 38 are fixedly connected to the side of the bottom plate 37 away from the supporting rod 36. The plurality of protrusions 38 are evenly distributed on one side of the bottom plate 37. When the bottom plate 37 contacts the ground, the protrusions 38 installed on the bottom plate 37 can increase the friction between the bottom plate 37 and the ground, thereby increasing the friction to improve the contact stability between the bottom plate 37 and the ground. A protective pad 39 is fixedly connected to the side of the threaded ring 35 close to the connecting block 33. The cross-section of the protective pad 39 is circular. When the threaded ring 35 rotates on the connecting rod 34 and connects with the connecting block 33, the protective pad 39 installed on the threaded ring 35 can avoid contact between the threaded ring 35 and the connecting block 33, thereby effectively avoiding contact between the two and causing wear.

[0037] The working principle of an exhaust gas emission device for electrostatic spraying provided by the utility model is as follows: when it is necessary to support the connecting pipeline 4, the fixing rod 201 is placed on the ground, and the limiting rod 209 is taken out from the limiting hole 206 and the inner wall of the fixing rod 201, and the angle of the arc plate 205 can be rotated by the adjusting rod 204 installed on the fixing block 203, and the arc plate 205 at one end of the arc surface of the fixing rod 201 is rotated so that the arc plate 205 is at the end of the fixing rod 201 close to the fixing block 203, so that the arc plate 205 can be unfolded, the connecting sleeve 207 and the contact plate 208 are connected to the arc plate 205, and then the contact plate 208 is connected to the connecting pipeline 4, and the end of the fixing rod 201 away from the fixing block 203 is connected to the ground When the contact is made, the support for the connecting pipeline 4 can be completed. When the limit rod 209 is connected to the arc plate 205 through the limit hole 206, the spring 210 installed on the limit rod 209 can improve the connection stability between the limit rod 209 and the arc plate 205, and prevent the limit rod 209 from slipping out of the limit hole 206. When the limit rod 209 is connected to the inner wall of the fixed rod 201, the guide block 211 installed on the limit rod 209 can increase the connection speed between the limit rod 209 and the fixed rod 201, thereby improving the connection efficiency of the two by increasing the connection speed. When the contact plate 208 is connected to the connecting pipeline 4, the anti-slip groove 212 opened on the contact plate 208 can improve the stability of the connection between the contact plate 208 and the connecting pipeline 4.

[0038] When the support device 2 encounters an uneven ground during use, the elastic plate 32 is first stretched to deform the elastic plate 32, and then the deformed elastic plate 32 is clamped on the surface of the limiting cylinder 31, and the connecting rod 34 is passed through the two connecting blocks 33, and then the threaded ring 35 is used to connect the connecting rod 34, so that the elastic plate 32 can be connected to the limiting cylinder 31 through the threaded ring 35, and the elastic plate 32 can be fixed on the limiting cylinder 31, and the angle of the support rod 36 is first adjusted, and then the angle of the bottom plate 37 is adjusted through the support rod 36, so that the angle of the support rod 36 and the angle of the bottom plate 37 are against the ground. The bottom plate 37 and the support rod 36 can improve the contact stability between the fixing rod 201 and the ground. When the bottom plate 37 contacts the ground, the protrusion 38 installed on the bottom plate 37 can increase the friction between the bottom plate 37 and the ground, thereby improving the contact stability between the bottom plate 37 and the ground by increasing the friction. When the threaded ring 35 rotates on the connecting rod 34 and connects with the connecting block 33, the protective pad 39 installed on the threaded ring 35 can avoid contact between the threaded ring 35 and the connecting block 33, thereby effectively avoiding contact between the two and causing wear.
