Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a multifunctional ductile iron straight pipe special coating production line. Background Art

[0002] Ductile iron straight pipes have multiple functions, the most important of which is used for conveying tap water. In the past, cement mortar linings used in ductile iron straight pipes had the phenomenon of "alkali return". Therefore, most of them now use spraying on ductile iron straight pipes as lining and surface protection. When spraying the coating on the ductile iron straight pipe, the straight pipe is first heated to a suitable temperature by a preheating device, and then the straight pipe is transported out of the preheating device and transferred to the spraying trolley through a pipe puller. The spraying trolley can make the straight pipe rotate and move axially, and the straight pipe is moved to the spraying device by the spraying trolley. Through the spraying device, the internal and external spraying of the straight pipe can be realized at the same time, and the construction of polyurethane and solvent-free epoxy resin coatings can be realized, and the construction of zinc-aluminum alloy and special resin paint coatings can be realized at the same time.

[0003] Since the spraying room adopts a closed space, negative pressure exhaust method is required to collect gas, which is treated by the exhaust gas treatment device and discharged in a qualified manner. The exhaust gas treatment device only needs to treat the exhaust gas through the internal activated carbon. When the exhaust gas passes through the activated carbon, the exhaust gas comes into contact with the activated carbon, and the pollutants in the exhaust gas will adhere to the activated carbon. At the same time, after the straight tube is sprayed, it needs to be transferred to the curing device for curing, and then transferred to the next process. However, during the treatment, activated carbon adsorption plates are used for adsorption, which takes a long time and has low efficiency.

[0004] Therefore, the Chinese patent with the authorization announcement number CN218871707U discloses a paint waste gas purification device, including a box, two activated carbon adsorption plates and a heating plate are fixedly installed on the box, the box is provided with air holes, a pump is fixedly installed on the box, the pump is fixedly connected with an air pipe, the air pipe extends out of the box, a plurality of pads are fixedly installed on the box, each of the pads is rotatably installed with a bracket, each of the brackets and the corresponding pads are installed with a rotating mechanism, each of the brackets is rotatably installed with a roller, and each of the brackets is installed with a locking mechanism that matches the corresponding roller. The advantages are: the air in the room can be absorbed and heated, and then the waste gas in the air is purified through the activated carbon adsorption plate, heating accelerates the adsorption speed, and the double-layer activated carbon adsorption plate improves the purification efficiency, making the purification more thorough.

[0005] In the above patent, the activated carbon on the side of the activated carbon adsorption plate close to the air inlet will fully contact with the exhaust gas so that the activated carbon can be saturated with absorption. After the activated carbon here is saturated with absorption, it will affect the entry of exhaust gas, so the activated carbon needs to be replaced. However, at this time, the activated carbon on the side of the activated carbon adsorption plate away from the air inlet has not reached the saturated adsorption state, and replacing the activated carbon will cause a waste of activated carbon. Therefore, this application provides a multifunctional ductile iron straight pipe special coating production line to meet the needs. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a multifunctional ductile iron straight pipe special coating production line to solve the problem that when the existing activated carbon is replaced, the activated carbon on the side away from the air inlet has not reached the adsorption saturation state, and replacing the activated carbon will cause waste of activated carbon.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0011] Optionally, a groove is provided on the elastic rod toward the opening of the V-shaped member, and a guide connecting rod is fixed inside the groove, and the guide connecting rod is used to prevent the elastic rod from bending in the axial direction of the circular shaft.

[0012] Optionally, a plurality of shifting blocks are arranged in a circular array on the inner wall of the filter cartridge, and when the filter cartridge rotates, the shifting blocks are used to drive the elastic rod to bend.

[0013] Optionally, a guiding surface 1 is provided on the shift block in the rotation direction toward the filter cartridge.

[0014] Optionally, an anti-jamming component is provided at the bottom of the elastic rod, and the anti-jamming component includes a paddle, and a plurality of vertical plates are provided on the paddle block. When the filter cartridge rotates, the paddle block can pass through the middle of two adjacent vertical plates.

[0015] Optionally, a curved portion is provided at the bottom of the shift block.

[0016] Optionally, an elastic strip is provided on the raised portion of the paddle.

[0017] Optionally, a second guide surface is provided on the side where the adjacent vertical plates are close to each other.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting a reduction motor, a filter cartridge and a cylinder body, when the exhaust gas treatment device is in operation, the reduction motor drives the filter cartridge to rotate, causing the activated carbon to flip, promoting exhaust gas turbulence, increasing the gas-solid relative velocity, and strengthening the mass transfer process, so that pollutants can diffuse faster to the surface of the activated carbon and be adsorbed, thereby accelerating the adsorption rate, reducing the exhaust gas residence time, and improving the equipment treatment efficiency. The activated carbon fully flips and contacts with the exhaust gas, and local premature saturation can be avoided, making full use of the activated carbon adsorption capacity, and more exhaust gas can be treated at the same amount of activated carbon, thereby improving the operation economy and exhaust gas treatment effect.

[0020] By setting up a flexible breaking-up component, the elastic rod can flexibly break up the agglomerated activated carbon to avoid damaging the activated carbon. The V-shaped parts on its surface increase the contact area and improve the breaking-up efficiency. It can also push away the activated carbon to protect the elastic rod and prevent excessive wear.

[0021] By arranging the guide connecting rod, the guide connecting rod in the groove of the elastic rod is ensured to bend in the rotation direction of the filter cartridge, thereby enhancing the stability of the elastic rod.

[0022] By setting the shifting block, the filter cartridge rotates to drive the shifting block to contact the elastic rod, so that the elastic rod further bends and rebounds, breaking up the activated carbon again to prevent agglomeration.

[0023] By setting up an anti-stuck material component, the vertical plate can also break up the activated carbon when the filter cartridge drives the activated carbon to flip, thereby improving the breaking efficiency. The paddle cooperates with the vertical plate and the paddle block, and guides the contact through the guide surface to prevent the activated carbon from being stuck between the vertical plates and between the elastic rod and the paddle block, thereby avoiding squeezing and damaging the activated carbon. The curved portion further stabilizes the movement of the paddle and protects the activated carbon. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] like Figures 1 to 12 As shown, an embodiment of the present invention provides a multifunctional ductile iron straight pipe special coating production line, including a preheating device 1, a spraying device 2, a curing device 3 and an exhaust gas treatment device 4. The straight pipe is moved into the preheating device 1 by a crane, and the straight pipe is preheated by the preheating device 1 to increase the initial temperature of the straight pipe, which is conducive to the adhesion of the coating. After the preheating of the straight pipe is completed, the straight pipe is transferred to the spraying trolley by a tube puller. The spraying trolley can make the straight pipe rotate and move axially. The straight pipe is moved to the spraying device 2 by the spraying trolley. The straight pipe can be sprayed inside and outside at the same time by the spraying device 2, so as to realize the construction of polyurethane and solvent-free epoxy resin coatings, and the construction of zinc-aluminum alloy and special resin paint coatings. Since the spraying room adopts a closed space, negative pressure exhaust method is required to collect gas, and the gas is passed into the exhaust gas treatment device 4 to treat the exhaust gas. At the same time, the straight pipe after spraying is moved to the curing device 3 by the trolley. The coating is cured by the curing device 3, and the multifunctional processing of the straight pipe is realized by the cooperation of multiple functions. The preheating device 1 is connected to the spraying device 2, the spraying device 2 is connected to the curing device 3, and the spraying device 2 is connected to the exhaust gas treatment device 4. The exhaust gas treatment device 4 includes a supporting leg 6, and a cylinder 5 is fixed on the top of the supporting leg 6. An air inlet 7 and an air outlet 8 are arranged on the circumferential surface of the cylinder 5. The air inlet 7 is arranged below the air outlet 8. The inner wall of the cylinder 5 is rotatably connected with a filter cartridge 11, and a reduction motor 9 is fixed on the surface of the cylinder 5. The output shaft of the reduction motor 9 movably penetrates the cylinder 5 and is fixed on the filter cartridge 11. A circular shaft 10 is fixedly penetrated at one end of the cylinder 5 away from the reduction motor 9, and the cylinder 5 is rotatably connected to the surface of the circular shaft 10. A warehouse door 12 is arranged on the side of the filter cartridge 11 away from the reduction motor 9. The filter cartridge 11 is filled with activated carbon, and the activated carbon occupies one third of the internal space of the filter cartridge 11.

[0046] The flexible breaking up component 13 includes a plurality of connecting rods 14, which are located in the filter cartridge 11 and fixed to the circumferential surface of the circular shaft 10. An elastic rod 15 is fixed to the bottom of the connecting rod 14, and the elastic rod 15 is used to break up the agglomerated activated carbon in the filter cartridge 11.

[0047] like Fig. 9As shown, a plurality of V-shaped members 16 are fixed on the surface of the elastic rod 15, and the opening of the V-shaped member 16 faces the rotation direction of the filter cartridge 11. The setting of the V-shaped member 16 increases the contact area between the elastic rod 15 and the activated carbon, and can more effectively act on a larger range of activated carbon when breaking up agglomerated activated carbon, thereby improving the breaking-up efficiency. The opening direction is consistent with the rotation direction of the filter cartridge 11, so that during the rotation of the filter cartridge 11, the V-shaped member 16 can better follow the movement trend of the airflow and the activated carbon, and more efficiently push away the activated carbon to avoid excessive accumulation of the activated carbon on the elastic rod 15. At the same time, it also protects the elastic rod 15, reduces excessive wear caused by frequent friction and collision with the activated carbon, and extends the service life of the elastic rod 15, thereby ensuring the long-term stable operation of the flexible breaking component 13 and maintaining the good adsorption performance of the activated carbon in the exhaust gas treatment device 4.

[0048] like Fig. 9 As shown, both sides of the V-shaped member 16 are wavy, and the V-shaped member 16 is an elastic member. The wavy design on both sides allows the irregular shape of the surface of the V-shaped member 16 to generate more disturbances when it contacts the activated carbon, thereby further enhancing the breaking up effect of the activated carbon and preventing the activated carbon from agglomerating. At the same time, as an elastic member, the V-shaped member 16 has a certain buffering capacity when colliding with the activated carbon, which can not only protect itself from being easily damaged, but also avoid excessive impact on the activated carbon and cause it to break, thereby ensuring that the integrity and adsorption performance of the activated carbon are not greatly affected, ensuring that the exhaust gas treatment device 4 has a stable and reliable purification effect on the exhaust gas, reducing the risk of secondary pollution caused by the breakage of the activated carbon, and improving the environmental protection performance and stability of the entire production line.

[0049] like Figure 8 and Fig.10 As shown, the elastic rod 15 is provided with a groove 17 at the opening of the V-shaped member 16, and a guide connecting rod 18 is fixed inside the groove 17. The guide connecting rod 18 is used to prevent the elastic rod 15 from bending in the axial direction of the circular shaft 10. The existence of the guide connecting rod 18 limits the bending direction of the elastic rod 15, so that it can only bend in the rotation direction of the filter cartridge 11. Such a design improves the stability and reliability of the elastic rod 15 during operation, ensures that it can move according to a predetermined trajectory and manner when breaking up the activated carbon, accurately acts on the agglomerated activated carbon, avoids collision damage to other components inside the filter cartridge 11 caused by the disordered swinging of the elastic rod 15, and is also conducive to improving the breaking effect, ensuring that the activated carbon in the exhaust gas treatment device 4 can maintain a good loose state, continuously and efficiently adsorb pollutants in the exhaust gas, extend the service life of the activated carbon, reduce production costs, and ensure the stable operation of the production line and the effectiveness of exhaust gas treatment.

[0050] like Figure 5As shown, the inner wall circular array of the filter cartridge 11 has a plurality of shift blocks 19. When the filter cartridge 11 rotates, the shift blocks 19 are used to drive the elastic rod 15 to bend. The setting of the shift blocks 19 provides an additional power source for the bending of the elastic rod 15. During the rotation of the filter cartridge 11, the shift blocks 19 periodically contact and bend the elastic rod 15. When the elastic rod 15 is separated from the shift blocks 19, a rebound force is generated. Such periodic bending and rebounding actions can produce a stronger impact force and disturbance effect on the agglomerated activated carbon, further improve the efficiency of breaking up the activated carbon, effectively prevent the aggravation of the agglomeration of the activated carbon, ensure that the activated carbon always maintains good adsorption performance, improve the purification capacity of the waste gas treatment device 4 for waste gas, ensure the environmental protection performance of the entire production line, and reduce the problems of decreased adsorption efficiency and increased equipment maintenance costs caused by activated carbon agglomeration.

[0051] like Fig.11 As shown, the shift block 19 is provided with a guide surface 20 in the rotation direction toward the filter cartridge 11. The existence of the guide surface 20 enables the shift block 19 to more smoothly guide the contact process between the two when contacting the anti-jamming component 21 at the bottom of the elastic rod 15. When the filter cartridge 11 rotates, the guide surface 20 can reduce the collision resistance and jamming phenomenon between the shift block 19 and the anti-jamming component 21, so that the shift block 19 can smoothly push the elastic rod 15 to bend, thereby avoiding equipment failure or damage caused by poor contact, improving the stability and reliability of equipment operation, and ensuring that the action of breaking up the activated carbon can be carried out continuously and effectively, thereby maintaining the activated carbon in the exhaust gas treatment device 4 in a good working state, ensuring the efficiency and stability of exhaust gas treatment, and ensuring the normal operation of the entire production line.

[0052] like Figure 6 to Figure 7 As shown, the bottom of the elastic rod 15 is provided with an anti-stuck material component 21, which includes a paddle 22. The paddle block 19 is provided with a plurality of vertical plates 25. When the filter cartridge 11 rotates, the paddle block 19 can pass through the middle of two adjacent vertical plates 25. The anti-stuck material component 21 is designed mainly to prevent the activated carbon from being stuck between the elastic rod 15 and the paddle block 19, and between the vertical plates 25. The paddle 22 can pull out the activated carbon that may be stuck between the paddle block 19 and the elastic rod 15 through its own shape and position changes when the paddle block 19 interacts with the elastic rod 15, so as to avoid the activated carbon from being stuck between the two. At the same time, the structural design that the shifting block 19 can pass through the middle of the vertical plate 25 can, on the one hand, use the vertical plate 25 to further break up the activated carbon during the rotation of the filter cartridge 11, thereby increasing the looseness of the activated carbon; on the other hand, it can also prevent the activated carbon from being stuck between the vertical plates 25, thereby ensuring the smoothness of the internal structure of the equipment, maintaining the stable operation of the exhaust gas treatment device 4, improving the utilization rate of the activated carbon and the exhaust gas treatment efficiency, reducing the equipment maintenance cost and the risk of downtime due to failures, and ensuring the efficient and stable operation of the entire production line.

[0053] like Figure 7 As shown, a bending portion 23 is provided at the bottom of the shift block 19. The bending portion 23 can better guide the movement trajectory of the shift block 19 during the contact between the shift block 19 and the anti-jamming component 21 at the bottom of the elastic rod 15, so that it can interact with the anti-jamming component 21 more stably. Especially in preventing activated carbon from getting stuck, the bending portion 23 can more smoothly push away the activated carbon that may be stuck between the bottom of the shift block 19 and other components, avoid wear or damage to equipment components due to jamming, and improve the reliability and durability of the equipment. At the same time, the stable movement trajectory also helps to improve the effect of the shift block 19 on the elastic rod 15, enhance the ability to break up agglomerated activated carbon, ensure the good state of the activated carbon in the exhaust gas treatment device 4, maintain efficient exhaust gas treatment capabilities, and ensure the normal operation and environmental protection performance of the production line.

[0054] like Figure 7 As shown, an elastic strip 24 is provided on the raised portion of the paddle 22, and the setting of the elastic strip 24 provides a certain elastic buffering capacity for the paddle 22. When the paddle 22 contacts the paddle block 19 or the activated carbon, the elastic strip 24 can absorb part of the impact force to prevent the paddle 22 from being damaged due to rigid collision, and at the same time can reduce excessive extrusion and wear of the activated carbon, protect the structural integrity of the activated carbon, and ensure that its adsorption performance is not greatly affected. In addition, the elastic effect of the elastic strip 24 can also enable the paddle 22 to better adapt to activated carbon of different shapes and positions during the contact process, improve the anti-stuck material effect, ensure smooth material flow inside the equipment, maintain the stable operation of the exhaust gas treatment device 4, improve the overall stability and reliability of the production line, and reduce the equipment maintenance cost and the risk of reduced exhaust gas treatment effect due to damage to the activated carbon.

[0055] like Fig.11 As shown, a second guide surface 26 is provided on one side where the adjacent vertical plates 25 are close to each other. The existence of the second guide surface 26 helps to guide the shift block 19 to enter between the two adjacent vertical plates 25 more accurately and smoothly during the rotation of the filter cartridge 11, thereby reducing the collision resistance and jamming between the shift block 19 and the vertical plates 25, and improving the smoothness and stability of the equipment operation. At the same time, this guiding effect is also conducive to preventing the activated carbon from accumulating and getting stuck near the vertical plates 25, ensuring that the vertical plates 25 can effectively break up the activated carbon, maintain the activated carbon in a good loose state, improve the adsorption efficiency of the activated carbon, ensure that the exhaust gas treatment device 4 has a stable and reliable purification effect on the exhaust gas, ensure the environmental protection performance and normal operation of the entire production line, and reduce problems such as production interruptions and cost increases caused by equipment failure or activated carbon agglomeration.

[0056] The working principle of the technical solution provided by the present invention is as follows:

[0057] Exhaust gas entry and activated carbon adsorption:

[0058] The exhaust gas enters the cylinder 5 through the air inlet 7. The inner wall of the cylinder 5 is rotatably connected with a filter cartridge 11. The filter cartridge 11 is filled with activated carbon that occupies one third of its internal space. When the exhaust gas enters the filter cartridge 11, it contacts the activated carbon, which adsorbs pollutants in the exhaust gas. The purified gas is discharged from the air outlet 8.

[0059] Activated carbon flipping enhances adsorption:

[0060] The reduction motor 9 fixed on the surface of the cylinder 5 works, and its output shaft drives the filter cylinder 11 to rotate on the circular shaft 10, so that the activated carbon inside the filter cylinder 11 turns over. The turning of the activated carbon promotes the turbulence of the exhaust gas in the filter cylinder 11, increases the relative speed between the exhaust gas and the activated carbon, and strengthens the mass transfer process, so that the pollutants in the exhaust gas can diffuse to the surface of the activated carbon for adsorption faster, speeds up the adsorption rate, reduces the residence time of the exhaust gas in the filter cylinder 11, improves the processing efficiency of the equipment, and avoids the problem of the overall adsorption efficiency decreasing due to premature adsorption saturation of local activated carbon, and makes full use of the adsorption capacity of the activated carbon;

[0061] Preventing activated carbon from agglomerating and related components:

[0062] The connecting rod 14 in the flexible breaking up assembly 13 is fixed on the circumferential surface of the circular shaft 10, and the elastic rod 15 at the bottom thereof is used to break up the agglomerated activated carbon. When the V-shaped piece 16 on the surface of the elastic rod 15 contacts the activated carbon, it can not only increase the contact area with the activated carbon and improve the breaking up efficiency, but also push away the activated carbon when the elastic rod 15 shuttles through the activated carbon, protecting the elastic rod 15 from excessive wear. The guide connecting rod 18 fixed in the groove 17 at the opening of the V-shaped piece 16 of the elastic rod 15 can make the elastic rod 15 bend only in the rotation direction of the filter cartridge 11, thereby enhancing the stability of the elastic rod 15;

[0063] When the filter cartridge 11 rotates, the guide surface 20 of the paddle block 19 on the inner wall circumferential array facing the rotation direction of the filter cartridge 11 contacts the anti-stuck material component 21 at the bottom of the elastic rod 15, and the paddle 22 in the anti-stuck material component 21 interacts with the paddle block 19, so that the paddle block 19 can pass through the middle of the adjacent vertical plates 25, and the paddle block 19 drives the elastic rod 15 to bend. When the elastic rod 15 is separated from the paddle block 19, a rebound force is generated to break up the activated carbon again, further preventing the activated carbon from agglomerating. At the same time, when the filter cartridge 11 drives the activated carbon to flip, the vertical plates 25 can also break up the activated carbon to improve the breaking efficiency. The cooperation between the paddle 22, the vertical plates 25 and the paddle block 19 can prevent the activated carbon from being stuck between the vertical plates 25 and between the elastic rod 15 and the paddle block 19, and prevent the elastic rod 15 from squeezing and damaging the activated carbon. The curved portion 23 at the bottom of the paddle 22 can further guide the movement of the paddle 22, making it more stable, and preventing squeezing and damaging the activated carbon.

[0064] Activated carbon replacement:

[0065] When the activated carbon needs to be replaced, the cylinder body 5 is opened, and the door 12 at the end of the filter cylinder 11 is opened to replace the activated carbon.

[0066] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
