Description

Technical Field

[0001] The invention relates to the technical field of spraying waste gas treatment, and in particular to a spraying waste gas treatment device. Background Art

[0002] Spraying is the process of using a spray gun to disperse paint or coating into uniform and fine droplets with the help of air pressure, so as to spray them evenly on the surface of the object. In this process, a certain amount of waste gas and waste paint will be generated. The waste gas will cause the air in the workplace to contain paint dust and volatile organic pollutants such as benzene and benzene derivatives, which is extremely harmful to spray painters. These waste gases directly discharged into the air will also affect the air quality.

[0003] When the bicycle parts are sprayed with paint in the paint room, waste gas treatment equipment will be installed to treat the waste gas generated during the spraying process, avoid direct discharge of waste gas, and reduce the harm to multiple workers.

[0004] In actual use, the existing spray waste gas treatment equipment will suck the gas together with some particulate matter into the equipment box through the exhaust pipe for treatment due to the exhaust fan. When the gas passes through the exhaust pipe, some attached particulate matter is easy to adhere to the inner wall of the exhaust pipe. The particulate matter attached to the pipe mouth is easy to be cleaned, but the particulate matter attached to the inner position of the exhaust pipe is difficult to be removed.

[0034] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0035] Through the central axis mechanism, air inlet control unit and adsorption unit, during the air inhalation process, the reciprocating screw is driven by the motor to rotate, so that the air inlet frame moves from left to right first. In this process, the air guide is driven to gradually expand outward under the action of the guide component, so that the channel on the surface of the air inlet frame is gradually opened. In this process, the flow speed of the gas after passing through the air inlet frame gradually slows down, and it starts to move from right to left after moving to the rightmost position of the reciprocating thread. In this process, the air guide is gradually closed, so that the channel on the air inlet frame is gradually blocked. In this process, the flow speed of the gas after passing through the air inlet frame gradually increases, and the speed is the largest after the air guide is reset to a cone shape. At the same time, during the left and right movement, the gas is preliminarily filtered under the action of the filter plate, so that large particles are blocked, and the outer wall of the air inlet frame can scrape the inner wall of the exhaust pipe during the movement, so that the particles adhering to the inner wall of the pipe are scraped off and finally pushed into the second receiving box for collection. In the process of moving to the initial state and continuing to move to the left, the extension plate gradually contacts the outer wall of the filter plate, and then the particles on the surface of the filter plate are cleaned and scraped off under the action of the rotating extension plate to avoid blockage. The rotating extension plate and cyclone plate can break up the gas in the suction pipe, making the gas distribution more uniform, which is helpful for subsequent treatment steps to treat the exhaust gas more efficiently. At the same time, the reciprocating screw will drive the fan blades to rotate, so that it produces wind blowing to the inlet side of the exhaust pipe, slowing down the gas flow rate, and increasing the residence time of the exhaust gas, so that the exhaust gas can fully contact and react with the spray water, activated carbon and other media, thereby improving the treatment effect. The reciprocating screw will also drive the driving gear to rotate, so that the outer gear ring can drive the activated carbon plate to rotate while being able to rotate around the inner gear ring. During the process, the surface of the activated carbon plate can be cleaned by the cleaning component, so that there is always a clean activated carbon plate at the air inlet groove, which improves the adsorption effect.

It is used to decelerate the drawn-in exhaust gas, slow down the speed at which the exhaust gas enters the spray chamber, and thereby increase the residence time of the exhaust gas, thereby improving the treatment effect.

[0070] like Figure 3 , Figure 5 , Figure 8 and Fig.12 As shown, the guide assembly 55 includes a retaining member 551 fixed to the exhaust pipe 32, a sealed bearing is installed in the middle of the retaining member 551, and the sealed bearing is sleeved on the reciprocating screw 41. A plurality of guide rails 552 adapted to the air guide member 54 are fixed to one side of the retaining member 551, and a guide groove is provided on the guide rail 552, and a guide block 553 is slidably installed in the guide groove.

In this state, the gas flow rate is maximum. When it moves on the inclined section of the guide rail 552, the air guide member 54 gradually expands under the action of the inclined guide rail 552, and the telescopic slot member 53 gradually contracts. When it moves to the rightmost end, the air guide member 54 is fully opened, and the telescopic slot member 53 is fully contracted together. At this time, the gas flow rate is minimum.

[0073] like Figure 8As shown, a reciprocating screw thread is provided on the outer wall of the reciprocating screw 41, a screw nut 51 adapted to the reciprocating screw thread on the reciprocating screw 41 is fixed at the axis of the air inlet frame 52, the air inlet frame 52 is assembled on the reciprocating screw 41 through the screw nut 51, and a filter plate 58 is assembled in the air inlet frame 52. When the reciprocating screw 41 rotates, the screw nut 51 is driven to move, thereby causing the air inlet frame 52 to move;

[0074] The air inlet frame 52 is provided with a through groove matched with the guide rail 552, a limit slide bar is fixed on the horizontal section of the guide rail 552, a through groove matched with the guide rail 552 is provided on the filter plate 58, a limit slide bar matched with the limit slide bar is provided on the inner wall of the through groove, and the through groove and the limit slide bar are in a sealed state with the guide rail 552 and the limit slide bar;

One end of the spray pipe 22 passes through the box body 11 and is fixed to the output end of the water pump 21. The input end of the water pump 21 is fixed with a water pump for extracting water for spraying;

[0076] Connect the water pump to an external clean water source, and after starting the water pump 21, water can be sent into the spray pipe 22 through the water pump pipe, and then sprayed into the inner cavity of the spray chamber through the nozzle 23, spraying the gas entering the spray chamber to remove soluble pollutants and fine particles in the exhaust gas;

[0077] like Figure 5 , Fig. 9 and Fig.10 As shown, the adsorption unit 60 includes a mounting cover 61, a circular groove is provided on one side of the mounting cover 61, a circular disc 62 is rotatably connected to one side of the inner wall of the circular groove, a plurality of air outlet mounting frames 63 are rotatably connected to the circular disc 62, an air inlet groove 65 is provided on the top of the inner wall of the mounting cover 61, and an activated carbon plate 64 adapted to the air inlet groove 65 is mounted on one side of the air outlet mounting frame 63;

[0078] An inner gear ring 66 is fixedly mounted on the other side of the inner wall of the circular groove, an outer gear ring 67 meshing with the inner gear ring 66 is fixedly mounted on one side of the air outlet mounting frame 63, a plurality of outer gear rings 67 are meshed with a driving gear 68 on the inner side thereof, the driving gear 68 is fixedly sleeved on the reciprocating screw 41, and a cleaning assembly 69 for cleaning the activated carbon plate 64 is mounted in the mounting cover 61;

[0079] The cleaning assembly 69 includes a shaft 691 rotatably connected to the inner wall of the mounting cover 61, a pulley is fixedly sleeved on the shaft 691 and the reciprocating screw 41, a transmission belt is meshed and connected to the two pulleys, a cleaning rod 692 is fixed to one end of the shaft 691, and a mounting groove is formed on the lower surface of the mounting cover 61, a third receiving box 693 is clamped in the mounting groove, and a tapered drop platform 694 is clamped on the surface of the third receiving box 693;

[0080] When the driving gear 68 rotates, it will drive the outer gear ring 67 and the air outlet mounting frame 63 to rotate on their own. At the same time, under the action of the inner gear ring 66, the outer gear ring 67 rotates with the air outlet mounting frame 63 while rotating around the inner gear ring 66, so that the activated carbon plate 64 located at the air inlet groove 65 can be rotated into the inner cavity of the mounting cover 61, and then be cleaned under the action of the rotating cleaning rod 692, so that it can maintain a clean state when it rotates to the air inlet groove 65 again. During the rotation of the air outlet mounting frame 63, it is in a sealed state with the disc 62, and the gas will not pass through the gap between the air outlet mounting frame 63 and the disc 62, and the disc 62 and the inner wall of the circular groove are also in a sealed state, so that when it rotates with the air outlet mounting frame 63, it can seal the air inlet groove 65 when the activated carbon plate 64 and the air inlet groove 65 are briefly separated.

[0081] like Figure 2 , Figure 3 and Figure 4 As shown, a plurality of ultraviolet sterilization lamps 70 are installed on the top wall of the sterilization chamber, and the ultraviolet sterilization lamps 70 can sterilize the gas after filtering, spraying and adsorption treatment.

[0082] Specifically, when the spraying waste gas treatment equipment is working / in use:

[0083] First, move the equipment to a suitable position, and then connect the water extraction pipe to an external clean water source. When spraying the bicycle parts, start the water pump 21 to send water into the spray pipe 22 through the water extraction pipe, and then spray it into the inner cavity of the spray chamber through the nozzle 23. Then start the exhaust fan 31 to generate suction at the inlet of the exhaust pipe 32, and then send the waste gas generated during the spraying process into the box body 11 through the exhaust pipe 32. At the same time, start the motor 42 to rotate the reciprocating screw 41, so that the extension plate 563 and the cyclone plate 561 rotate, and then disperse the gas sucked into the pipeline, so that the gas distribution is more uniform.

[0084] Under the action of the reciprocating thread and the lead screw nut 51, the air inlet frame 52 moves back and forth left and right. When the air inlet frame 52 moves from left to right with the air guide 54, when it moves along the horizontal section of the guide rail 552, the air guide 54 is always in a closed state, and the gas passing through the air guide 54 is accelerated. In this state, the gas flow rate is the largest. When gradually moving along the inclined section of the guide rail 552, the air guide 54 gradually expands under the action of the inclined guide rail 552, and the telescopic slot member 53 gradually shrinks. When it moves to the rightmost end, the air guide 54 is fully opened under the action of the guide rail 552, and the telescopic slot member 53 is completely shrunk together. At this time, the gas flow rate is the smallest.

[0085] After the gas enters the exhaust pipe 32, it is first filtered by the filter plate 58, so that the large particles attached to the gas are filtered out. At the same time, during the movement, the outer wall of the air inlet frame 52 scrapes the inner wall of the exhaust pipe 32 in real time to scrape off the particles adhering to the inner wall of the pipe. When the air inlet frame 52 moves to the left until the push rod 565 abuts against the cover plate 564, the air inlet frame 52 continues to move to the left, and the push rod 565 can push the cover plate 564 to slide to the left, so that the discharge chute is opened, so that the scraped particles are pushed into the second receiving box 566 for collection, and in this process, the extension plate 563 gradually contacts and abuts against the outer wall of the filter plate 58, and then the particles on the surface of the filter plate 58 are cleaned and scraped off under the action of the rotating extension plate 563.

[0086] After the gas passes through the air guide 54, the wind blown by the rotating blowing fan blades 57 contacts the gas, slowing down the flow rate of the gas and increasing the residence time of the gas, so that the gas can stay in the spray chamber and the adsorption chamber for a longer time. After the gas enters the spray chamber, it contacts the mist water sprayed by the nozzle 23, so that the water-soluble or particulate components in the gas are absorbed or settled by the water. The sewage is filtered by the symmetrical inclined filter sheet 15 and falls into the waste liquid collection chamber 12 for collection. The settled particulate matter is collected by the first receiving box 14.

[0087] When the reciprocating screw 41 rotates, it also drives the driving gear 68 to rotate. The rotation of the driving gear 68 drives the outer gear ring 67 and the air outlet mounting frame 63 to rotate. At the same time, under the action of the inner gear ring 66, the outer gear ring 67 rotates with the air outlet mounting frame 63 while rotating around the inner gear ring 66, so that the activated carbon plate 64 located at the air inlet groove 65 can be rotated into the inner cavity of the mounting cover 61, and then cleaned under the action of the rotating cleaning rod 692, so that it can be kept in a clean state when it rotates to the air inlet groove 65 again, and the cleaned waste gradually enters the third receiving box 693 for collection. In this state, the gas treated by the spray chamber is adsorbed by the activated carbon plate 64 and enters the sterilization chamber, and finally is discharged to the outside of the box body 11 after being irradiated by the ultraviolet sterilization lamp 70;

[0088] After use, remove the receiving boxes and dump the collected waste.
