Description

Technical Field

[0001] The present application relates to the technical field of paint mist exhaust gas treatment devices, and in particular to a spray element for paint mist exhaust gas treatment. Background Art

[0002] In the prior art, after a product is spray-painted, paint mist exhaust is generated. The paint mist exhaust contains powder and paint mist, and cannot be directly discharged into the external air to avoid pollution. Therefore, the paint exhaust gas needs to be recovered and processed.

[0003] In the prior art, when treating paint mist exhaust gas, a water curtain is usually set in the device to filter the paint mist exhaust gas. When the paint mist exhaust gas passes through the water curtain, the dust or paint in it combines with water, thereby increasing its weight and falling, accelerating the speed of separation from the gas, thereby effectively achieving separation.

[0004] In the paint mist exhaust gas treatment device of the prior art, the water curtain is realized by a spray pipe or a spray head, and a plurality of thinner water outlets are arranged on the spray pipe or the spray head, and the liquid is sprayed out from the water outlet to form a water curtain; however, in actual use, the liquid used to form the water curtain is circulated, that is, after the water curtain is formed, the liquid falls into the water tank, and after simple treatment, it is circulated to the spray pipe or the spray head, and the water is discharged again to form a water curtain, thereby saving water resources; however, this will cause dust or paint blocks to remain in the liquid, which will block the water outlet of the spray pipe or the spray head, thereby making the water curtain incomplete, and then reducing the effect of paint mist purification.

[0005] Therefore, the spraying parts in the prior art have room for further improvement. Utility Model Content

[0006] In view of this, in order to solve the technical problem that the water outlet of the spray pipe or spray head in the paint mist exhaust gas treatment device in the above-mentioned prior art is easily clogged, the present application provides a spray part, which is provided with a water outlet mechanism, and the water outlet mechanism is located between the water inlet and the water outlet. The water outlet mechanism is used to rotate and swing the liquid in the direction of the water outlet, so that the liquid has a larger water outlet pressure when it is discharged, and the liquid is rotated and thrown out, and the force on the dust and paint at the water outlet is multi-directional, so that the dust and paint at the water outlet can be easily brought out by the liquid, and the water outlet is not easily clogged, so as to ensure the stability of the water curtain formed in the paint mist treatment device, thereby ensuring the paint mist purification effectiveness of the paint mist exhaust gas treatment device.

[0007] The present application discloses a spray element for treating paint mist exhaust gas, comprising a water inlet mechanism and a water outlet mechanism, wherein the water inlet mechanism comprises a first opening and a second opening, wherein the first opening is a water inlet, and the first opening and the second opening are distributed along the axial direction;

[0008] The water outlet mechanism is at least partially located in the water inlet mechanism, and a water outlet is formed between the water outlet mechanism and an end portion of the second open end;

[0009] Among them, the water outlet mechanism is rotatably connected to the water inlet mechanism, and the water outlet mechanism is provided with blades, which are arranged inclined in the axial direction.

In particular, the water outlet mechanism is rotatably connected to the water inlet mechanism, and the first opening and the second opening are distributed along the axial direction. When the liquid enters the water inlet mechanism from the first opening and flows to the second opening, the liquid acts on the water outlet mechanism. Since the water outlet mechanism is rotatably connected to the water inlet mechanism, the liquid will act on the blades after acting on the water outlet mechanism.

The blades rotate under the continuous impact of the liquid. At the same time, the blades also change the flow direction of the liquid, and throw the liquid out during rotation, so that when the liquid flows to the water outlet, it has a greater rotational impact force, and then the water can be rotated out of the water outlet to form a water curtain. At the same time, the greater impact force and multi-angle and multi-directional forces will bring out the dust and paint at the water outlet, which can prevent dust or paint blocks from clogging the water outlet to ensure the integrity and effectiveness of the water curtain.

[0047] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is described in detail, clearly, and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

Therefore, the above terms cannot be understood as limiting this application.

[0050] The present application will be described in further detail below with reference to the accompanying drawings. Figures 1 to 5 illustrate.

[0051] The present application provides a spray element 1 for treating paint mist exhaust gas (hereinafter referred to as the spray element), which is used in a paint mist exhaust gas treatment device to generate a water curtain to assist in separating the paint mist exhaust gas.

[0052] Specifically, such as Figures 1 to 4As shown, the spray element 1 includes a water inlet mechanism 11 and a water outlet mechanism 12. One end of the water inlet mechanism 11 is connected to the water inlet pipe, and the other end cooperates with the water outlet mechanism 12 to discharge water, so that a water curtain is formed after the spray element 1 discharges water; in this embodiment, the water inlet mechanism 11 includes a first opening 1111 and a second opening 1112, and the first opening 1111 and the second opening 1112 are arranged in an axial distribution, wherein the first opening 1111 is a water inlet, and the second opening 1112 cooperates with the water outlet mechanism 12 to form a water outlet; the water outlet mechanism 12 is rotatably connected to the water inlet mechanism 11, and a blade 122 is provided on the water inlet mechanism 11, and the blade 122 is arranged in a plurality, and the plurality of blades 122 are arranged at equal intervals, wherein the blade 122 is arranged obliquely to the axial direction, and the blade 122 is located between the water inlet and the water outlet, and the blade 122 as a whole is basically facing the first opening 1111 In the direction, when the liquid enters the water inlet mechanism 11 from the first opening 1111 and flows to the second opening 1112, the liquid acts on the water outlet mechanism 12. Since the water outlet mechanism 12 is rotatably connected to the water inlet mechanism 11, after the liquid acts on the water outlet mechanism 12, it will act on the blades 122. Since the blades 122 are arranged obliquely in the axial direction, the axial force of the liquid on the blades 122 will be converted into a circumferential force, thereby driving the blades 122 to rotate. The blades 122 rotate under the continuous impact of the liquid. At the same time, the blades 122 also change the flow direction of the liquid, and throw the liquid out during rotation, so that when the liquid flows to the water outlet, it has a larger rotational impact force, and then the water can be rotated out of the water outlet to form a water curtain. At the same time, the larger impact force can prevent dust or paint blocks from clogging the water outlet to ensure the integrity and effectiveness of the water curtain.

[0053] In this embodiment, the liquid provides rotational force to the guide member 121, and at the same time, the guide member 121 cooperates with the blade 122 to change the flow direction of the liquid and rotate the liquid out. That is, the water outlet mechanism 12 of the present application does not require additional external driving force, and can achieve self-driven rotation, which can effectively achieve resource conservation.

[0054] Further, such as Figures 2 to 4As shown, the water inlet mechanism 11 includes a water inlet cylinder 111 and a connecting assembly. The water inlet cylinder 111 is a cylindrical structure. The first opening 1111 and the second opening 1112 are respectively arranged on the opposite ends of the water inlet cylinder 111. The first opening 1111 and the second opening 1112 are coaxially arranged. The first opening 1111 is located above the second opening 1112. The diameter of the first opening 1111 is smaller than the diameter of the second opening 1112. The connecting assembly is at least partially located in the water inlet cylinder 111 and at least partially passes through the second opening 1112. One end of the connecting assembly is fixedly connected to the water inlet cylinder 111, and the other end is rotatably connected to the water outlet mechanism 12. Among them, the water outlet mechanism 12 also includes a guide member 121. The guide member 121 is provided with a rotation hole. The guide member 121 is sleeved on the connecting assembly through the rotation hole, so that the guide member 121 is rotatably connected to the connecting assembly. Figure 2 As shown, the guide member 121 is partially located in the water inlet cylinder 111, and the end surface of the guide member 121 facing the second opening 1112 is a tapered structure, so that the upper end of the guide member 121 is small and the lower end is larger, so that the end surface of the guide member 121 facing the second opening 1112 is inclined, which has a guiding effect on the liquid. When the liquid enters from the first opening 1111 and falls on the guide member 121, the guide member 121 guides the liquid to the water outlets around it, so that the water curtain formed by the liquid sprayed by the spray member 1 can be more uniform and complete; Figure 4 As shown, the blades 122 are arranged on the conical end face of the guide member 121. The blades 122 are arranged circumferentially along the end face of the guide member 121. When the blades 122 rotate following the guide member 121, the liquid is evenly rotated and thrown out to the water outlet, so that the water outlet is not easily blocked and the water curtain is formed more complete and evenly.

[0055] A water outlet is formed between the end surface of the guide member 121 and the second opening 1112. Figure 2 As shown, the water outlet is an annular structure. Along the axial direction, there is a distance between the bottom of the water inlet cylinder 111 and the guide member 121, which is the water outlet. It can be seen that the water outlet is in the extension direction of the conical surface of the guide member 121, that is, when the liquid is guided by the conical surface of the guide member 121, it will flow toward the water outlet along the trend, ensuring the smoothness of the water outlet of the spray member 1; even if the guide member 121 does not rotate, it can also ensure that an effective water curtain is formed after the spray member 1 discharges water.

[0056] It should be noted that the axial width of the water outlet of the present application is larger than the water outlet aperture of a general spray pipe, thereby reducing the probability of the water outlet being blocked by dust or paint blocks.

[0057] In another optional embodiment of the present application, the blade 122 is further expanded; Figures 2 to 3As shown, the blade 122 is completely located in the water inlet cylinder 111. In the axial direction, the bottom of the blade 122 is higher than the bottom of the second opening 1112 of the water inlet cylinder 111, and the outer diameter of the blade 122 is smaller than the inner diameter of the water inlet cylinder 111, so as to ensure that the blade 122 can act on the liquid while avoiding interference with the water inlet cylinder 111 when the blade 122 rotates, thereby ensuring the smooth rotation of the blade 122.

[0058] like Figure 2 、 Figure 4 As shown, the blade 122 includes a connecting end and a free end 1223, the connecting end being the end of the blade 122 connected to the guide member 121, and the free end 1223 being the end of the blade 122 not connected to the guide member 121, wherein the free end 1223 extends circumferentially in a direction away from the connecting end, and the distance between the free end 1223 and the central axis is greater than the distance between the connecting end and the central axis, as shown in FIG. Figure 4 As shown, the blade 122 is tilted as a whole so that the end face of the blade 122 is tilted with the axial direction and the horizontal plane, so that the end face of the blade 122 is facing the first opening 1111. At the same time, when the liquid acts on the end face of the blade 122 along the axial direction, the axial force of the liquid acts on the end face of the blade 122, which can better convert the axial force into a circumferential force, thereby providing a force for the guide member 121 to rotate. At the same time, when the guide member 121 rotates, it will change the flow direction of the liquid and convert the axial displacement of the liquid. When the guide member 121 rotates, it will throw out the liquid and give the liquid a larger rotational impact force, which can avoid dust clogging at the water outlet.

[0059] Among them, such as Figure 2 、 Figure 4 As shown, the connection end is divided into a first connection end 1221 and a second connection end 1222, the first connection end 1221 and the second connection end 1222 are distributed along the axial direction, and the projections of the first connection end 1221 and the second connection end 1222 on the central axis do not overlap, that is, the first connection end 1221 and the second connection end 1222 are not at the same axial height, wherein the first connection end 1221 is located above the second connection end 1222; the distance between the first connection end 1221 and the central axis is smaller than the distance between the second connection end 1222 and the central axis, that is, the first connection end 1221 is closer to the central axis, and the second connection end 1222 extends outward, so that the blade 122 appears as shown in FIG. Figure 4 The inclined shape shown makes the blade 122 have a tendency to follow the inclination of the tapered end surface of the guide member 121, which can improve the sensitivity of the rotation of the guide member 121.

[0060] In this embodiment, a guide channel is formed between the blades 122, one end of the guide channel faces the first opening 1111, and the other end faces the second opening 1112. The guide channel is tilted as a whole, and is distributed circumferentially between the upper and lower ends. When the liquid is located between the guide channels, the liquid is guided to rotate so that the liquid can be better rotated and thrown out. Figure 2 As shown, the inner wall of the second opening 1112 is an arc-shaped surface, the tapered surface of the guide member 121 is an arc-shaped structure, the inner wall of the bottom of the water inlet cylinder 111 is an arc-shaped surface, and the bottom thickness of the water inlet cylinder 111 is small, so that the inner wall of the bottom of the water inlet cylinder 111 is an arched arc surface; and the tapered surface of the guide member 121 is an arc-shaped concave surface, as shown in FIG. Figure 5 As shown, the arc surface trend of the inner wall at the bottom of the water inlet cylinder 111 is similar to the arc surface trend of the conical surface of the guide member 121, so as to increase the guiding force on the liquid. At the same time, the conical surface of the guide member 121 and the bottom inner wall of the water inlet cylinder 111 form a water outlet with a gradually decreasing opening, thereby increasing the pressure of the liquid when it is sprayed out from the water outlet, so as to expand the distance of the liquid spraying, so that the water curtain formed by the spray member 1 is larger, more complete and better.

[0061] like Figure 2 、 Figure 3 As shown, the guide member 121 includes a guide portion 1211, which is a conical structure, and the blade 122 is arranged on the guide portion 1211; the guide portion 1211 and the second opening 1112 of the water inlet cylinder 111 form a water outlet, the center of the guide portion 1211 is located in the water inlet cylinder 111, and the side of the guide portion 1211 extends radially downward out of the water inlet cylinder 111, so that after the liquid is sprayed out from the water outlet, it will then be thrown out along the end face of the guide portion 1211, thereby increasing the endurance of the liquid and increasing the stability of the water curtain formation.

[0062] In another optional embodiment of the present application, the water inlet mechanism 11 is further expanded; Figure 2 、 Figure 3 As shown, the connecting assembly includes a connecting member 112 and a limiting member 113. The connecting member 112 is a columnar structure as a whole. Figure 3As shown, the upper end of the connecting member 112 is located in the water inlet cylinder 111, and the upper end of the connecting member 112 is connected to the water inlet cylinder 111 through a connecting column. There are at least two connecting columns, one end of the connecting column is connected to the outer wall of the connecting member 112, and the other end is connected to the inner wall of the water inlet cylinder 111, so as to fix the connecting member 112 to the water inlet cylinder 111; wherein, the end of the connecting member 112 does not exceed the first opening 1111; the lower end of the connecting member 112 is rotatably connected to the guide part 1211 of the guide member 121, and the guide part 1211 is provided with a rotating hole. The connecting member 112 passes through the rotating hole and is exposed to the outside of the guide member 121. The part of the connecting member 112 exposed to the rotating member 114 is connected to the limit member 113, and the limit member 113 is detachably connected to the connecting member 112, thereby limiting the axial displacement of the guide member 121 on the connecting member 112; in this embodiment, the limit member 113 is threadedly connected to the connecting member 112.

[0063] In this embodiment, correspondingly, the connecting member 112 is provided with a limiting block (not shown in the figure) at the upper end of the guide portion 1211 , thereby cooperating with the limiting member 113 at the bottom to axially limit the guide portion 1211 .

[0064] Furthermore, based on the above embodiment, the connection component is further improved; Figures 2 to 3 As shown, the guide member 121 further includes a connecting portion 1212. The guide portion 1211 and the connecting portion 1212 are distributed along the axial direction. The guide portion 1211 is located at the upper end of the connecting portion 1212. A first rotation hole is provided on the guide portion 1211, and a second rotation hole is provided on the connecting portion 1212. Figures 1 to 3 As shown, the connecting portion 1212 includes a connecting platform and support columns 1212.1. There are at least two support columns 1212.1. The upper ends of the support columns 1212.1 are connected to the bottom of the guide portion 1211, and the lower ends of the support columns 1212.1 are connected to the connecting platform. The support columns 1212.1 are arranged at equal intervals along the circumference of the connecting platform. The circumferential diameter formed by the support columns 1212.1 and the guide portion 1211 is larger than the circumferential diameter formed with the support platform 1212.2, so as to increase the support effect on the guide portion 1211, and can also reduce the volume and reduce the rotational load.

[0065] In this embodiment, if Figure 2As shown, the second rotating hole is arranged on the support platform 1212.2, and the aperture of the second rotating hole is smaller than the aperture of the first rotating hole; the connecting assembly also includes a rotating member 114, and a rotating groove 1121 is provided at the end of the connecting member 112 away from the first opening 1111, and the rotating groove 1121 is at the entrance of the end of the connecting member 112 away from the first opening 1111. The upper end of the rotating member 114 is arranged in the rotating groove 1121, and the lower end of the rotating member 114 passes through the second rotating hole and is connected to the limit member 113; wherein a bearing 115 is provided on the outside of the rotating member 114, the inner wall of the bearing 115 is in contact with the connecting member 112, and the outer wall of the bearing 115 is in contact with the inner wall of the rotating groove 1121, that is, the rotating member 114 is rotatably connected to the connecting member 112 through the bearing 115.

[0066] Specifically, the rotating member 114 includes a first portion and a second portion, the first portion and the second portion are coaxially arranged, the outer diameter of the first portion is larger than the outer diameter of the second portion, the first portion is arranged in the rotating groove 1121 and is rotatably connected to the connecting member 112, and the second portion passes through the second rotating hole and is connected to the limiting member 113; in this embodiment, the outer diameter of the first portion is larger than the outer diameter of the second rotating hole, the outer diameter of the second portion is almost the same as the inner diameter of the second rotating hole, the outer diameter of the limiting member 113 is larger than the outer diameter of the second rotating hole, and the second portion is provided with a thread so that the second portion is threadedly connected to the limiting member 113; in this embodiment In the figure, the second part and the limit member 113 cooperate to clamp the support platform 1212.2, so that the second part and the support platform 1212.2 are relatively fixed. When the guide member 121 rotates, it drives the rotating member 114 to rotate relative to the connecting member 112. The advantage of this arrangement is that the rotating connecting part 1212 is arranged at the lower end of the water inlet and the water outlet, which reduces the probability of liquid contacting the rotating part, avoids dust from entering the rotating part to cause blockage, and reduces the corrosion of the rotating part by the liquid, thereby improving the service life and working stability of the spray part 1.

[0067] Furthermore, Figure 2 、 Figure 3 As shown, a limit seat 116 is provided at the open end of the rotating groove 1121, and the outer side of the limit seat 116 is in contact with the inner wall of the rotating groove 1121. The limit seat 116 is used to limit the displacement of the bearing 115 in the axial direction. A limit ring is also provided between the bearings 115 to ensure that the bearing 115 will not easily displace axially in the rotating groove 1121.

[0068] like Figure 2 、 Figure 3 As shown, the connecting member 112 includes a conical portion and a straight cylindrical portion, the conical portion is connected to the upper end of the straight cylindrical portion, and the guide member 121 is sleeved on the straight cylindrical portion. The inclination trend of the conical surface of the conical portion is the same as the inclination trend of the conical surface of the guide member 121 to increase the guiding property of the liquid.

[0069] In another optional embodiment of the present application, the spray element 1 is further expanded; Figure 2、 Figure 3 As shown, the spray member 1 also includes a diverter 13, which is connected to the end of the connecting member 112 of the connecting assembly near the first opening 1111; wherein, the end of the diverter 13 facing the first opening 1111 is a conical structure, that is, the upper end of the diverter 13 is set to a conical structure, and in the first opening 1111 at the upper end of the diverter 13, the outer diameter of the diverter 13 is smaller than the diameter of the first opening 1111, so that when the liquid enters the water inlet cylinder 111 from the first opening 1111, it is diverted by the conical part of the diverter 13, so that the liquid flows more evenly to the surroundings, thereby ensuring the effectiveness and integrity of the water curtain formation.

[0070] It should be noted that the spray element 1 of the present application can also be used in other scenarios where gas separation is required.
