Description

Technical Field

[0001] This utility model relates to the field of formaldehyde removal, specifically to a chemical formaldehyde spraying device. Background Technology

[0002] Formaldehyde is a colorless gas with a strong, pungent odor and is the simplest aldehyde compound. It is widely used in industry and daily life, especially in construction, furniture, and household chemicals. Formaldehyde can be synthesized industrially or produced naturally, such as in forest fires and vehicle emissions. It is commonly used in the manufacture of engineered wood products like plywood, particleboard, and medium-density fiberboard, as well as in furniture, flooring, and wallpaper as an adhesive. However, formaldehyde is a toxic carcinogen; long-term or high-concentration exposure can cause respiratory diseases, allergic reactions, and may even be linked to certain cancers. To address industrial formaldehyde production, some projects construct formaldehyde spray systems to remove formaldehyde from the air. These systems adsorb, decompose, or neutralize formaldehyde molecules in the air by spraying liquid solvents or chemical agents, thereby reducing the formaldehyde concentration.

[0003] Existing formaldehyde spraying devices typically spray liquid solvents or adsorbents into the air. These solvents or adsorbents have certain chemical components that can react with formaldehyde, transforming it into harmless substances, or adsorbing formaldehyde onto the liquid surface. However, the structure of these spraying devices is mostly fixed nozzles, which have a limited spray range and usually cannot effectively remove formaldehyde located at the edges of the device. This results in the need for multiple cycles of treatment, greatly increasing the processing time. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a chemical formaldehyde spraying device to solve the technical problem that existing formaldehyde spraying devices have fixed nozzle positions and effectively remove formaldehyde located at the edge of the device, which leads to the need for multiple cycles of treatment and greatly increases the processing time.

[0005] Based on the above objectives, this utility model provides a chemical formaldehyde spraying device, including a tank for containing formaldehyde, and a spraying mechanism for removing formaldehyde installed inside the tank. The spraying mechanism includes a fixing ring fixedly installed inside the tank, and an installation piece fixedly provided on the inner wall of the fixing ring.

[0006] The mounting plate is equipped with a flow tube, and the flow tube has multiple sets of nozzles for spraying out the solution. Each nozzle has a tail plug and a drive assembly for driving the flow tube to swing.

[0007] The drive assembly includes a connector for connecting to a flow pipe, an outer cylinder connected to the tail end of the connector, multiple sets of blades fixed inside the outer cylinder and the connector, a docking hole opened inside the connector, a docking post for rotatably connecting with the docking hole at one end of the outer cylinder, a nozzle for driving the connector to rotate inside the outer cylinder, and a swing rod movably mounted thereon, with baffles and limit blocks at the front and rear ends of the swing rod, respectively, and a plug on the surface of the baffles.

[0008] The outer cylinder is further provided with an inner cylinder, and the inner cylinder is provided with a gear connected to the docking column. The gear surface is provided with meshing toothed columns, and a turntable is fixed at the tail end of the toothed columns. The surface of the turntable is provided with a lever, and the bottom end of the lever is provided with a rotating frame that is movably connected to the swing arm.

[0009] Preferably, the tail plug includes a pull tab, one side of which is provided with a sealing plug, and a drain needle is fixedly mounted on the sealing plug.

[0010] Preferably, a first bearing is sleeved around the sealing plug, and a second bearing is sleeved around the connector. The sealing plug and the connector are connected to the mounting plate through the first bearing and the second bearing.

[0011] Preferably, a water inlet pipe is fixedly installed at the top of the tank, and an air inlet pipe and an exhaust pipe are installed on the outside of the tank.

[0012] Preferably, the upper part of the tank body is provided with multiple sets of fastening plates, and the lower part of the tank body is provided with multiple sets of hanging plates.

[0013] Preferably, a control cabinet is also provided on one side of the tank.

[0014] Preferably, a liquid storage tank is provided on one side of the control cabinet, and an outlet pipe that matches the inlet pipe is fixedly provided on the surface of the liquid storage tank.

[0015] Preferably, the back of the liquid storage tank is provided with a treatment tank that matches the drain pipe.

[0016] Preferably, a water pump is also fixedly connected to the back of the liquid storage tank.

[0017] Preferably, the outer cylinder is matched with the water inlet pipe.

[0018] The beneficial effects of this utility model are:

[0019] This invention involves injecting a high-velocity liquid capable of removing formaldehyde into the drive assembly. The high-speed liquid rushes into the outer cylinder and exits through an open nozzle, impacting fixed blades inside the connector. The blades, under pressure, cause the connector to rotate, while the flow pipe moves circumferentially around its axis. During blade rotation, a gear meshes with a toothed column, causing it to rotate. This rotating column then drives a turntable at its tail end, causing a pendulum-like motion of a lever. The pendulum-like lever, via a rotating frame, causes a mechanism located inside the outer cylinder... The pendulum swings, and when it swings, the baffle at the front end of the pendulum, in conjunction with the blockage on the surface of the baffle, blocks the nozzle that is currently in operation. When the previous nozzle is blocked, the solution will spray out from the other nozzle and continue to impact the blades, causing the blades to drive the connector to rotate in the opposite direction, thereby resetting the flow tube and continuing to perform circular motion in the opposite direction, thus completing one pendulum cycle. This process repeats continuously, allowing the flow tube to swing continuously. The nozzles located on the surface of the flow tube can spray the solution into the space inside the tank to the greatest extent, greatly improving the utilization efficiency of the solution and thus improving the formaldehyde removal effect.

[0032] To further understand this utility model, a detailed description of it will be provided below with reference to the accompanying drawings.

[0033] Combination Figure 1 and Figures 3-7 This utility model provides a chemical formaldehyde spraying device, including a tank 1 for containing formaldehyde, and a spraying mechanism 6 for removing formaldehyde installed inside the tank 1. The spraying mechanism 6 includes a fixing ring 61 fixedly installed inside the tank 1, and an installation piece 62 is fixedly provided on the inner wall of the fixing ring 61.

[0034] The mounting plate 62 is equipped with a flow tube 63, and the flow tube 63 is provided with multiple sets of nozzles 631 for spraying out solution. The nozzles 631 are respectively provided with tail plugs 64 and drive components 65 for driving the flow tube 63 to swing.

[0035] The drive assembly 65 includes a connector 651 for connecting to the flow pipe 63, an outer cylinder 652 connected to the tail end of the connector 651, multiple sets of blades 6511 fixed inside the outer cylinder 652 and the connector 651 having a docking hole 6512 inside the connector 651, a docking post 6521 for rotatably connecting with the docking hole 6512 at one end of the outer cylinder 652, a nozzle 6522 for driving the connector 651 to rotate inside the outer cylinder 652, and a swing rod 6523 movably mounted thereon. The swing rod 6523 has a baffle 6524 and a limiting block 6526 at its front and rear ends, respectively, and a plug 6525 on the surface of the baffle 6524.

[0036] The outer cylinder 652 is further provided with an inner cylinder 654. Inside the inner cylinder 654, there is a gear 6541 connected to the docking column 6521. The surface of the gear 6541 is provided with a toothed column 6542. The tail end of the toothed column 6542 is fixed with a turntable 6543. The surface of the turntable 6543 is provided with a lever 6544. The bottom end of the lever 6544 is provided with a rotating frame 6545 that is movably connected to the swing rod 6523.

[0037] In this embodiment, the formaldehyde gas to be treated is first sent into the tank 1. Then, a high-flow-rate liquid that can remove formaldehyde, such as ammonia, methanol solution, sulfite and hydrogen peroxide solution, is injected into the drive assembly 65. At this time, the high-speed liquid rushes into the outer cylinder 652. After entering the outer cylinder 652, the high-speed liquid will rush out from an open nozzle 6522 and impact the blade 6511 fixed inside the connector 651. After the blade 6511 is subjected to force, it drives the connector 651 to rotate. At the same time, the flow pipe 63 will rotate around its axis as the connector 651 rotates. At this time, the solution will also flow into the flow pipe 63 and then be sprayed out from the nozzle 631 on the flow pipe 63 to absorb the formaldehyde inside the tank 1.

[0038] Secondly, during the rotation of the blade 6511, the gear 6541 is driven to rotate. The rotating gear 6541 meshes with the toothed column 6542, causing it to rotate. The rotating toothed column 6542 then drives the turntable 6543 at its tail end to rotate. The rotating turntable 6543 causes the lever 6544 to perform a pendulum motion. The pendulum lever 6544, through the rotating frame 6545, causes the pendulum rod 6523 located inside the outer cylinder 652 to swing. The front end of the pendulum rod 6523 is rotatably fixed in the outer cylinder 652. When the pendulum rod 6523 swings, the baffle 6524 at the front end of the pendulum rod 6523, in conjunction with the plug 6525 on the surface of the baffle 6524, blocks the nozzle 6522 that is in operation.

[0039] Finally, when the previous nozzle 6522 is blocked, the solution will be sprayed out from the other nozzle and continue to impact the blade 6511, causing the blade 6511 to drive the connector 651 to rotate in the opposite direction, thereby resetting the flow tube 63 and continuing to perform circular motion in the opposite direction, thus allowing the flow tube 63 to complete one pendulum cycle. In this way, the flow tube 63 can swing continuously, and the nozzle 631 located on the surface of the flow tube 63 can spray the solution into the space inside the tank 1 to the maximum extent, greatly improving the utilization efficiency of the solution, thereby improving the formaldehyde removal effect.

[0040] Combination Figure 4 The tail plug 64 includes a pull-out buckle 641, one side of which is provided with a sealing plug 642, and a unclogging needle 643 is fixedly provided on the sealing plug 642.

[0041] In this embodiment, the tail plug 64 is used to block the other end of the flow tube 63 so that the inside of the flow tube 63 always maintains a suitable pressure. The buckle 641 is set to facilitate the worker to pull out the sealing plug 642 located in the flow tube 63. The unblocking needle 643 of the sealing plug 642 is used to unblock the blocked nozzle 631.

[0042] Combination Figure 4 and Figure 5 The sealing plug 642 is surrounded by a first bearing 644, and the connector 651 is surrounded by a second bearing 653. The sealing plug 642 and the connector 651 are connected to the mounting plate 62 through the first bearing 644 and the second bearing 653.

[0043] In this embodiment, the arrangement of the first bearing 644 and the second bearing 653 can reduce the friction between the flow pipe 63 and the mounting plate 62 during the swinging process, so that the rotating or sliding components can move smoothly and reduce energy loss. At the same time, the first bearing 644 and the second bearing 653 can reduce the radial load and axial load borne by the flow pipe 63 during the movement.

[0044] Combination Figure 1 The tank body 1 is fixedly provided with a water inlet pipe 11 at the top, and an air inlet pipe 12 and an exhaust pipe 13 are provided on the outside of the tank body 1.

[0045] In this embodiment, the solution can be sent into the drive assembly 65 through the water inlet pipe 11, so that the drive assembly 65 provides basic operating power for the entire spraying mechanism 6. The air inlet pipe 12 can send the formaldehyde gas to be treated into the tank 1, and the discharge pipe 13 is used to discharge the saturated solution after absorbing the formaldehyde gas.

[0046] Combination Figure 2 The upper part of the tank body 1 is also provided with multiple sets of fasteners 14, and the lower part of the tank body 1 is also provided with multiple sets of hanging pieces 15.

[0047] In this embodiment, the fastener 14 is used to ensure that the can body 1 and the can lid are installed tightly and securely, so as to prevent the outside air from affecting the formaldehyde treatment process inside the can body 1, while the hanging piece 15 facilitates the handling and transportation of the can body 1.

[0048] Combination Figure 1 A control cabinet 2 is also provided on one side of the tank body 1.

[0049] In this embodiment, the control cabinet 2 on one side of the tank 1 is used to control the flow rate of the water inlet pipe 11, the air inlet pipe 12 and the drain pipe 13. The water inlet pipe 11, the air inlet pipe 12 and the drain pipe 13 are all equipped with electrically controlled solenoid valves. With the help of the control cabinet 2, the formaldehyde inside the tank 1 can be treated more accurately and efficiently.

[0050] Combination Figure 1 A liquid storage tank 3 is provided on one side of the control cabinet 2, and an outlet pipe 31 that matches the inlet pipe 11 is fixedly provided on the surface of the liquid storage tank 3.

[0051] In this embodiment, the liquid storage tank 3 is filled with a liquid that easily absorbs formaldehyde. The solution can be smoothly delivered to the drive assembly 65 through the water outlet pipe 31 and the water inlet pipe 11 fixed on the surface of the liquid storage tank 3.

[0052] Combination Figure 1 The back of the liquid storage tank 3 is equipped with a treatment tank 4 that matches the drain pipe 13.

[0053] In this embodiment, after the saturated solution filled with formaldehyde is discharged from the drain pipe 13, it will enter the treatment tank 4 for final treatment, thereby converting it into a harmless liquid.

[0054] Combination Figure 1 A water pump 5 is also fixedly connected to the back of the liquid storage tank 3.

[0055] In this embodiment, the water pump 5 can not only extract the treatment solution located inside the storage tank 3, but also pressurize the solution and deliver it to the drive assembly 65.

[0056] Combination Figure 1 and Figure 2 The outer cylinder 652 is matched with the water inlet pipe 11.

[0057] In this embodiment, after the outer cylinder 652 is connected to the water inlet pipe 11, it can receive the treatment solution flowing in from the water inlet pipe 11.
