Description

Technical Field

[0001] The invention relates to the technical field of flue gas treatment, and in particular to waste gas purification treatment equipment. Background Art

[0002] Flue gas contains a large amount of dust, oxides, heavy metals and other harmful substances, and purification equipment is needed to remove particulate matter and pollutants in the flue gas.

[0003] The patent with patent announcement number CN215085933U relates to a high-efficiency smoke dust treatment equipment for steel mills, which belongs to the technical field of smoke treatment in steel mills, including a base, a purification box, a vacuum cleaner, a vacuum pipe and a gas pipe. A purification box is fixedly installed on the top of the base, and a vacuum cleaner is fixedly installed on one side of the purification box. A purification mechanism, a servo motor, a rotating rod, a connecting plate, a fixed sleeve, a support plate, a mounting block and an electric telescopic rod are arranged inside the purification box. Among them, a servo motor is fixedly installed above the purification box, and a rotating rod is installed above the servo motor through its own output shaft. When the device body is sucking the smoke in the steel mill workshop, the patent can adjust the angle of the vacuum pipe so that the vacuum pipe can suck the smoke inside the workshop from multiple directions, increase the vacuuming area, and thereby increase the environment inside the workshop, prevent the staff from inhaling dust into their lungs, and thereby improve the practicality of the device when in use.

[0004] The above patent has the function of adjusting the angle of the dust suction pipe. By installing a rotating rod on the output shaft, the angle of the dust suction pipe can be adjusted when sucking the smoke inside the workshop, which effectively increases the dust suction area and prevents the particulate matter and pollutants in the smoke from being inhaled by the workers, thereby improving the safety at work. However, an activated carbon plate is arranged inside the purification box to purify the air. Only one side of the fixed activated carbon plate is in contact with the smoke. Since the gas can only contact one side of the activated carbon plate, the rate at which the activated carbon adsorbs the gas will be slowed down, thereby causing the purification process to be prolonged.

[0014] The present invention provides a waste gas purification treatment device. It has the following beneficial effects:

[0015] (1) In the waste gas purification treatment equipment of the present invention, the movement of the rotating rod drives the movement of the carrying plate, and the movement of the carrying plate drives the movement of the activated carbon plate. The activated carbon plate is driven by the force of the driving motor to rotate around the T-shaped rod, so that the gas inside the protective shell and the activated carbon plate can contact more fully, thereby improving the adsorption effect of the activated carbon plate. The rotation of the rotating rod drives the rotation of the carrying plate, and the rotation of the carrying plate drives the rotation of the activated carbon plate. The activated carbon plate rotates around the T-shaped rod while rotating, thereby avoiding frequent contact between the gas and one side of the activated carbon plate and less contact with the other side, thereby effectively improving the use effect of the activated carbon plate.

[0016] (2) In the waste gas purification treatment equipment of the present invention, the limit rod is separated from the inner wall of the circular hole of the limit plate during movement, so that the limit imposed by the limit rod on the limit plate is released. The limit rod is used to limit the movement of the limit plate, ensuring that the loading plate will not move due to irregular operations during operation, thereby effectively improving the standardization of operation. The rubber sheet applies a thrust to the surface of the loading plate during movement, so that the movement of the rubber sheet drives the loading plate to move. After the limit is released, the loading plate drives the filter plate to pop out automatically, saving the operator's replacement time, thereby improving work efficiency.

[0017] (3) In the waste gas purification treatment equipment of the invention, the bottom of the baffle contacts the inner wall of the square box during movement, so that the baffle seals the bottom of the square box. When the filter plate is removed, the bottom of the square box is automatically sealed to prevent gas from leaking from the gap, causing pollutants to enter the operator's nasal cavity and endanger the operator's life. The stretched No. 3 scroll spring recovers and drives the knocking plate to rotate. The knocking plate contacts the surface of the push rod during rotation. After the knocking plate accumulates force, it collides with the push rod to generate vibration, and then transmits the vibration to the circular block to prevent the circular block from getting stuck after long-term use.

[0029] See also Figure 1-4, one embodiment of the present invention is: an exhaust gas purification treatment device, comprising a bottom plate 1, a protective shell 2 is fixedly installed on the top of the bottom plate 1, an exhaust pipe 3 is fixedly penetrated on the top of the protective shell 2, a rectangular box 41 is fixedly penetrated on the surface of the protective shell 2, an air intake pipe 42 is fixedly penetrated on the surface of the rectangular box 41, a valve 43 is fixedly installed on the surface of the air intake pipe 42, a driving motor 51 is fixedly penetrated on the surface of the bottom plate 1, a hollow ring 52 is fixedly installed on the output end of the driving motor 51, and a fan blade 53 is fixedly installed on the surface of the hollow ring 52, and also includes a purification device; wherein the purification device includes a T-shaped rod 61, a bent rod 62, a hollow circular tube 63, a rotating rod 64, a mounting plate 65, an activated carbon plate 66, a gear 67, a door-shaped plate 68 and The disc 69 and the T-shaped rod 61 are fixedly mounted on the output end of the driving motor 51, the bent rod 62 is fixedly mounted on the surface of the T-shaped rod 61, the hollow circular tube 63 is fixedly mounted on the top of the bent rod 62, the rotating rod 64 is rotatably mounted on the inner wall of the hollow circular tube 63, the carrying plate 65 is fixedly mounted on the surface of the rotating rod 64, the activated carbon plate 66 is fixedly mounted inside the carrying plate 65, the gear 67 is fixedly mounted on the surface of the rotating rod 64 away from the carrying plate 65, the gate plate 68 is fixedly mounted on the top of the inner wall of the protective shell 2, and the disc 69 is fixedly mounted on the bottom of the gate plate 68. The movement of the activated carbon plate 66 is achieved by the force of the driving motor 51, so that the contact area between the activated carbon plate 66 and the gas is increased, which helps to improve the adsorption effect of the activated carbon plate 66.

[0030] A tooth block is fixedly installed at the bottom of the disc 69, which meshes with the gear 67. A rectangular groove is provided on the surface of the activated carbon plate 66. Through the meshing relationship between the gear 67 and the tooth block, the activated carbon plate 66 can rotate around the T-bar 61 while rotating on its own, effectively increasing the contact area between the gas and both sides of the activated carbon plate 66.

[0031] When the present embodiment is working, the driving motor 51 is started, the output end of the driving motor 51 rotates to drive the hollow ring 52 to rotate, the hollow ring 52 rotates to drive the fan blades 53 to move, and the fan blades 53 generate upward airflow during the movement. At the same time, the output end of the driving motor 51 rotates to drive the T-shaped rod 61 to rotate, the T-shaped rod 61 rotates to drive the bending rod 62 to move, the bending rod 62 moves to drive the hollow circular tube 63 to move, the hollow circular tube 63 moves to drive the rotating rod 64 to move, the rotating rod 64 moves to drive the carrying plate 65 to move, and the carrying plate 65 moves to drive the activated carbon plate 66 to move. The movement of the activated carbon plate 66 is achieved by the force of the driving motor 51, which helps to increase the contact area. The rotating rod 64 rotates and drives the gear 67 to move. Since the gear 67 is meshed with the tooth block at the bottom of the disk 69, the gear 67 rotates during the movement. The rotation of the gear 67 drives the rotating rod 64 to rotate. The rotation of the rotating rod 64 drives the carrying plate 65 to rotate. The rotation of the carrying plate 65 drives the activated carbon plate 66 to rotate. Through the meshing relationship between the gear 67 and the tooth block, the activated carbon plate 66 can move and rotate at the same time, thereby improving the use effect of the activated carbon plate 66.

[0032] See also Figure 1-9 On the basis of the above embodiment, another embodiment of the present invention further includes a loading and unloading device and a protective device; the loading and unloading device includes a square box 71, an air pipe 72, a loading plate 73, a filter plate 74, a limit plate 75, a mounting plate 76, a cylindrical shaft 77, a push rod 78, a limit rod 79, a slider 710, a Z-shaped sheet 711, a long rod 712 and a rubber sheet 713, the square box 71 is fixedly mounted on the top of the exhaust pipe 3, the air pipe 72 is fixedly mounted on the top of the square box 71, the loading plate 73 slides through the inner and outer walls of the square box 71, the filter plate 74 is fixedly mounted on the inside of the loading plate 73, the limit plate 75 is fixedly mounted on the surface of the loading plate 73, the mounting plate 76 is fixedly mounted on the surface of the square box 71, the cylindrical shaft 77, the push rod 78, the limit rod 79, the slider 710, the Z-shaped sheet 711, the long rod 712 and the rubber sheet 713, the square box 71 is fixedly mounted on the top of the exhaust pipe 3, the air pipe 72 is fixedly mounted on the top of the square box 71, the loading plate 73 slides through the inner and outer walls of the square box 71, the filter plate 74 is fixedly mounted on the inside of the loading plate 73, the limit plate 75 is fixedly mounted on the surface of the loading plate 73, the mounting plate 76 is fixedly mounted on the surface of the square box 71, The cylindrical shaft 77 rotates and passes through the surface of the mounting plate 76, the pushing rod 78 is fixedly mounted on the surface of the cylindrical shaft 77, the limiting rod 79 is fixedly mounted on the surface of the pushing rod 78 close to the limiting plate 75, the slider 710 is slidably mounted on the inner wall of the square box 71, the Z-shaped piece 711 is fixedly mounted on the surface of the slider 710, the end of the Z-shaped piece 711 away from the slider 710 is fixedly mounted on the inner wall of the square box 71, the long rod 712 is fixedly mounted on the surface of the slider 710, and the rubber sheet 713 is fixedly mounted on the surface of the long rod 712. By installing a limiting plate 75 on each side of the loading plate 73, it is prevented that the loading plate 73 may move accidentally due to improper operation by the operator during work, thereby reducing the adverse effects caused by accidental touch.

[0033] A circular hole is provided on the surface of the limit plate 75, and a No. 1 spiral spring is arranged between the cylindrical shaft 77 and the mounting plate 76. The limit rod 79 contacts the inner wall of the circular hole. Through the contact between the limit rod 79 and the circular hole on the limit plate 75, the limit rod 79 limits the movement of the limit plate 75 to avoid the formation of gaps that may cause gas leakage.

[0034] The Z-shaped piece 711 itself is elastic, and the rubber piece 713 contacts the side of the loading plate 73 away from the limiting plate 75. By installing the elastic Z-shaped piece 711, it is ensured that the slider 710 can move smoothly under the influence of the Z-shaped piece 711 after the operator releases the limit.

[0035] The protective device includes a circular block 81, a baffle 82, a transmission belt 83, a contact plate 84, a long plate 85, a push rod 86 and a knocking plate 87.

When the filter plate 74 is removed, the baffle 82 rotates upward to automatically seal the bottom of the square box 71 to prevent gas leakage during disassembly to endanger the safety of the operator.

[0036] A No. 2 scroll spring is arranged between the circular block 81 and the square box 71. The surface of the baffle 82 close to the square box 71 contacts the inner wall of the square box 71. When the No. 2 scroll spring is restored, the circular block 81 can be driven to rotate, so that the circular block 81 can be smoothly restored to the initial position after rotation, preparing for the next work.

[0037] The knocking plate 87 itself is elastic, and the knocking plate 87 is in contact with the surface of the push rod 86. A No. 3 spiral spring is arranged between the knocking plate 87 and the long plate 85. After the knocking plate 87 accumulates force, it collides with the push rod 86 to generate vibration, and then transmits the vibration to the circular block 81, so as to prevent the circular block 81 from getting stuck during long-term use.

[0038] The locking cam 77 is in the state of being moved away from the locking cam 76, and the locking cam 78 is in the state of being moved away from the locking cam 76. When the locking cam 77 is in the state of being moved away from the locking cam 76, the locking cam 76 is in the state of being moved away from the locking cam 76. The Z-shaped sheet 711 is restored by its own elasticity, and the restoration drives the slider 710 to move toward the limit plate 75. The movement of the slider 710 drives the long rod 712 to move toward the limit plate 75. The movement of the long rod 712 drives the rubber sheet 713 to move toward the limit plate 75. The rubber sheet 713 applies a thrust to the surface of the loading plate 73 during the movement, so that the movement of the rubber sheet 713 drives the loading plate 73 to move away from the square box 71. The movement of the loading plate 73 drives the filter plate 74 to move away from the square box 71. After the limit is released, the loading plate 73 drives the filter plate 74 to automatically pop out, thereby effectively improving the working efficiency.

[0039] When the long rod 712 moves toward the limit plate 75, it contacts the surface of the contact plate 84, so that the movement of the long rod 712 drives the contact plate 84 to move toward the long plate 85. The movement of the contact plate 84 drives the transmission belt 83 to rotate. The rotation of the transmission belt 83 drives the circular block 81 to rotate toward the long plate 85. The circular block 81 stretches the second scroll spring during the rotation. At the same time, the rotation of the circular block 81 drives the baffle 82 to rotate upward. The baffle 82 stops moving after rotating to a predetermined position. The bottom of the baffle 82 contacts the inner wall of the square box 71 during the movement, so that the baffle 82 seals the bottom of the square box 71. The baffle 82 is automatically sealed when the filter plate 74 is removed to avoid gas generation. Leakage, the contact plate 84 contacts the side of the knocking plate 87 close to the push rod 86 during the movement, so that the movement of the contact plate 84 drives the knocking plate 87 to rotate, and the surface of the knocking plate 87 in contact with the push rod 86 during the rotation is separated. At the same time, the knocking plate 87 stretches the No. 3 scroll spring during the rotation, and the contact plate 84 continues to move and separates from the surface in contact with the knocking plate 87. The stretched No. 3 scroll spring recovers and drives the knocking plate 87 to rotate squarely toward the push rod 86. The knocking plate 87 contacts the surface of the push rod 86 during the rotation, and the knocking plate 87 accumulates force and collides with the push rod 86 to generate vibration, which is then transmitted to the circular block 81 to prevent the circular block 81 from getting stuck during long-term use.
