Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, specifically to a boiler room return water treatment device for tire production. Background Technology

[0002] During the tire production process, the boiler room continuously generates a large amount of return water, which contains various impurities such as iron filings, rust, scale, and metal fragments. Direct discharge of this water would waste water resources and pollute the environment. Therefore, the return water from the boiler room is filtered, purified, and recycled to achieve the goals of energy conservation, environmental protection, and reduced production costs.

[0003] Existing membrane filtration equipment used for boiler water return in tire manufacturing plants has the following drawbacks: Firstly, existing equipment typically uses traditional membrane filtration to treat boiler room return water. Since the return water contains a large amount of hard impurities such as iron filings, scale, and metal fragments, it is very easy to cause the filter membrane to become clogged. Moreover, once clogged, it is extremely difficult to clean and cannot be cleared quickly and effectively. Frequent disassembly of the equipment is required for cleaning or replacing the membrane modules, which not only increases the workload and maintenance costs of manual maintenance, but also leads to prolonged equipment downtime, affecting the overall filtration efficiency and making it difficult to meet the needs of continuous treatment of return water in the tire production process. Secondly, the existing equipment's flow guidance and centrifugal separation structure are not properly matched. The influent is usually not scientifically diverted and its flow rate is not controlled. The impact force of the water flow can easily damage the internal flow guidance components, and a stable vortex flow state cannot be formed, resulting in poor centrifugal separation effect. Impurities in the return water are not completely separated, the efficiency is low, and it is difficult to meet the needs of subsequent filtration processes. Third, the existing equipment has an unreasonable slag discharge structure design and lacks an efficient automatic slag discharge mechanism. Hard impurities such as iron filings and oxide scale intercepted during the filtration process tend to accumulate on the surface of the filter membrane and in the slag discharge channel, which aggravates the clogging of the filter membrane and leads to poor slag discharge. It requires frequent manual disassembly of the equipment to clean the accumulated impurities, which not only increases the cost of manual maintenance and extends the downtime of the equipment, but also easily damages the filter membrane and slag discharge components during the cleaning process, further shortening the service life of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a boiler room return water treatment device for tire production. The device draws return water through a return water pump, separates easily clogged hard impurities through a centrifugal device, and performs multi-stage fine filtration with a primary filter cartridge and a cartridge-type fine filter cartridge. Residual impurities are adsorbed by an auxiliary discharge component, and impurities are automatically discharged through a slag discharge component.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1.

The separation hood of this invention adopts a funnel-shaped design, which facilitates the collection of the thrown impurities; the stabilizing frame at the bottom of the clean water drain pipe can ensure the stability of the separation disc when rotating at high speed and reduce component wear; the impurities scraped off by the scraper are automatically discharged through the drive motor of the slag discharge assembly, which drives the main shaft and spiral blades, eliminating the need for frequent manual cleaning. This collaborative design not only reduces the equipment failure rate, simplifies the maintenance process, and reduces labor costs, but also extends the overall service life of the equipment.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0019] like Figures 1-10 As shown, a boiler room return water treatment device for tire production includes: a return water pump 1, an inlet pipe 2 at one end of the return water pump 1, a centrifuge cylinder 3 connected to one end of the inlet pipe 2, and a centrifugal device 4 inside the centrifuge cylinder 3; the centrifugal device 4 includes a flow guiding component 41 and a separation component 42 that are connected to each other; the flow guiding component 41 includes a vortex guide plate 411 and a flow guide cover 412 sleeved on the outside of the vortex guide plate 411; the separation component 42 has a separation cover 421 and a separation disc 422 rotatably connected inside the separation cover 421; one end of the centrifugal device 4 has a clean water outlet 5, and the other end of the centrifugal device 4 has a slag discharge pipe 6 and a slag discharge component 7 connected to the slag discharge pipe 6; both the clean water outlet 5 and the slag discharge component 7 are equipped with auxiliary discharge components 8. Return water is drawn by the return water pump 1 and transported to the centrifugal device 4 inside the centrifugal drum 3 through the water inlet pipe 2. The flow guiding component 41 and the separation component 42 work together to separate impurities. The clean water is discharged through the clean water outlet 5, and the impurities are discharged through the slag discharge component 7. The auxiliary discharge component 8 helps to adsorb residual impurities, thereby realizing the integrated operation of return water extraction, separation, filtration and slag discharge, and improving the integration of the equipment. The components work together to form a complete return water treatment process without the need for additional auxiliary equipment, which improves the integration and simplifies the operation process.

[0020] The purified water outlet 5 is connected to a pre-filter cartridge 9 via a pipe, and the other end of the pre-filter cartridge 9 is connected to a cartridge-type fine filter cartridge 10 via a pipe. The purified water separated by the centrifugal device 4 first passes through the pre-filter cartridge 9 to filter out residual fine impurities in the water, and then passes through the cartridge-type fine filter cartridge 10 for further filtration to remove the remaining impurities. This achieves multi-stage fine filtration of the return water, improving the purification purity of the return water to meet recycling standards. This removes various impurities from the water, and compared to traditional single-stage filtration methods, the filtration effect is more thorough, ensuring that the purified return water can be safely recycled.

[0021] A flow guide shroud 412 is located inside the centrifuge cylinder 3. The top of the flow guide shroud 412 is connected to the water inlet pipe 2. The water inlet pipe 2 is equipped with a water inlet valve 21. The inner cavity of the flow guide shroud 412 is equipped with a flow divider cone 413 connected to multiple vortex flow guide plates 411. The multiple vortex flow guide plates 411 are arranged in a ring array on the bottom side wall of the flow divider cone 413. The bottom end of the flow guide shroud 412 is connected to a venturi shroud 414, which is fitted on the outside of the multiple vortex flow guide plates 411. The bottom end of the flow guide shroud 412 is also equipped with a protective cover 415. The system stabilizes and regulates the water flow, protects the internal guide components, and provides suitable water flow velocity conditions for subsequent centrifugal separation. The inlet valve 21 controls the inlet water flow rate, and the diverting cone 413 diverts the inlet water to reduce the impact force of the water flow and avoid damage to the vortex guide plate 411. The annular array of vortex guide plates 411 guides the water flow to form a stable vortex. The venturi cover 414 further regulates the water flow velocity and flow rate to ensure that the water flow enters the separation component 42 in a stable spiral shape. The protective cover 415 prevents impurities from entering the connection between the guide component 41 and the separation component 42 and avoids component wear.

[0022] The top of the separation hood 421 is sealed and connected to the protective cover 415. The inner cavity of the separation hood 421 is funnel-shaped, and the bottom of the separation hood 421 is sealed and connected to a diversion hopper 11. The top of the diversion hopper 11 has an opening that communicates with the separation hood 421. The diversion hopper 11 is arranged in a disc-spiral shape, and two discharge pipes 111 are provided on both sides of the diversion hopper 11. The funnel-shaped separation hood 421 allows impurities thrown off by centrifugation to quickly slide to the bottom. The disc-spiral diversion hopper 11 slows down the falling speed of impurities, preventing impurities from accumulating and clogging. The two discharge pipes 111 can transport impurities simultaneously, improving slag discharge efficiency. The sealed connection prevents impurities from leaking to the clean water side, ensuring the purity of the clean water.

[0023] A purified water drain pipe 12 is provided at the bottom of the separating disc 422. The other end of the purified water drain pipe 12 is connected to the purified water outlet 5. A stabilizing frame 13 is rotatably connected to the bottom of the purified water drain pipe 12. One end of the stabilizing frame 13 is connected to the inner wall of the centrifuge cylinder 3. The purified water drain pipe 12 can quickly transport the purified water filtered by the separating disc 422 to the purified water outlet 5. The stabilizing frame 13 can fix the purified water drain pipe 12, prevent the purified water drain pipe 12 from shaking when the separating disc 422 rotates at high speed, reduce friction and wear between components, and improve the stability of the separating disc 422 during rotation, ensuring a smooth centrifugal separation process.

[0024] The top of the separating disc 422 is provided with a plurality of guide plates 423 arranged in a ring array. The guide plates 423 are all arc-shaped. The bottom center of the separating disc 422 is provided with a water inlet 424. The inner cavity of the water inlet 424 is provided with a filter layer 425. The top of the water inlet 424 corresponds to the bottom opening of the venturi cover 414. The outer wall of the separating disc 422 is provided with a plurality of connecting rods 426. One end of each connecting rod 426 is connected to a scraper rod 427. One end of each scraper rod 427 abuts against the inner wall of the separating cover 421. The outer wall of the separating disc 422 is provided with a toothed ring 428. A bevel gear 429 is meshed on the outer wall of the toothed ring 428. One end of the bevel gear 429 is connected to a drive motor 4210. The drive motor 4210 is located on the outer wall of the separating cover 421. The drive motor 4210 drives the bevel gear 429 to mesh and rotate with the gear ring 428, thereby driving the separation disc 422 to rotate at high speed. The arc-shaped guide plate 423 enhances the kinetic energy of the water flow rotation and uses centrifugal force to throw heavy impurities onto the inner wall of the separation hood 421. The scraper rod 427 rotates with the separation disc 422 and scrapes the impurities on the inner wall to the diversion outlet hopper 11. The filter layer 425 can perform preliminary filtration of the water flow and further intercept fine impurities. The water inlet 424 corresponds to the opening of the venturi hood 414 to ensure that the water flows smoothly into the clean water drain pipe 12, thereby achieving efficient centrifugal separation and automatic scraping of impurities, improving separation efficiency and reducing the workload of manual cleaning.

[0025] The slag discharge assembly 7 includes a slag discharge hopper 71 connected to the slag discharge pipe 6. A second drive motor 72 is installed on the outer wall of the slag discharge hopper 71. A main shaft 73 is installed at the power output end of the second drive motor 72. A spiral blade 74 is installed on the outer side of the main shaft 73. The main shaft 73 and the spiral blade 74 are rotatably mounted in the inner cavity of the slag discharge pipe 6. The other end of the slag discharge pipe 6 is connected to the discharge pipe 111. Impurities in the diversion discharge hopper 11 enter the slag discharge pipe 6 through the discharge pipe 111. The second drive motor 72 drives the main shaft 73 and the spiral blade 74 to rotate. Through the pushing action of the spiral blade 74, the impurities are stably discharged from the slag discharge pipe 6 without the need for frequent manual cleaning, realizing automated slag discharge. At the same time, it avoids the accumulation of impurities and blockage of the pipe, ensuring continuous operation of the equipment, thereby realizing automatic and continuous discharge of impurities, avoiding the accumulation of impurities and blockage, and reducing manual maintenance costs.

[0026] The auxiliary discharge assembly 8 includes a spiral insulating rod 81 sleeved on the outer wall of the purified water outlet 5 and the outer wall of the slag discharge pipe 6. The spiral insulating rod 81 has multiple electromagnetic blocks 82 arranged in an array. These electromagnetic blocks 82 can be controlled by an existing electromagnetic stepper controller connected via wires. The control method involves sequentially energizing and de-energizing the electromagnetic blocks 82 from one end to the other, generating magnetic force to attract residual fine metal impurities in the water flow. This causes the metal impurities to move towards the output end of the slag discharge pipe 6 under the sequential attraction of the electromagnetic blocks 82 until they are discharged. When energized, the electromagnetic blocks 82 generate magnetic force, attracting residual fine metal impurities in the purified water outlet 5 and the slag discharge pipe 6. The spiral insulating rod 81 can fix the electromagnetic blocks 82 and guide the impurities, preventing them from being discharged with the purified water, ensuring a more thorough purification effect in the returned water, further improving the purity of the returned water, and preventing residual impurities from affecting recycling.

[0027] Working principle: Open the inlet valve 21 and start the return water pump 1. The return water pump 1 can extract the return water generated in the boiler room during the tire production process. The extracted return water contains a variety of impurities, specifically contaminated iron filings and rust, oxide scale that has fallen off the inner wall of the pipe, metal fragments generated by wear and corrosion of vulcanizing equipment and heat exchange equipment during operation, as well as welding slag, metal particles and other impurities remaining after pipe maintenance and modification. The return water pump 1 pumps the extracted return water through the inlet pipe 2 to the inside of the guide shroud 412. The diverting cone 413 inside the guide shroud 412 diverts the incoming water flow, causing it to disperse radially. The flow is then concentrated by the Venturi shroud 414, which is connected to the guide shroud 412, and further diverted by the vortex guide plate 411. The diverting cone 413 diverts the incoming water flow primarily to reduce its impact force and prevent direct impact on the vortex guide plate 411, which could damage it. Furthermore, the diverted water flow can interact with multiple vortices... The flow guide plate 411 makes more uniform contact, which facilitates the formation of a stable vortex flow trend after the water flows through the vortex guide plate 411. During the process of water flowing through the Venturi shroud 414, the flow velocity and flow rate are effectively regulated by the changes in the internal spatial structure of the Venturi shroud 414. This can effectively avoid the failure to form a stable vortex flow state due to the attenuation of rotational force caused by the water flow velocity being too low or the flow rate being too high. As a result, the centrifugal force on the impurities is insufficient, and they cannot be effectively separated from the water flow, which ultimately affects the efficiency and effect of impurity separation. When the water flows out from the bottom opening of the Venturi shroud 414, it presents a stable spiral flow state. At this time, drive motor 4210 is started. Drive motor 4210 drives bevel gear 429 to mesh and rotate with gear ring 428, thereby driving separation disc 422 to rotate at high speed. The high-speed rotation direction of separation disc 422 is consistent with the spiral flow direction of water. When water comes into contact with separation disc 422, separation disc 422 applies secondary rotational kinetic energy to water, causing water and its contained iron filings, oxide scale, metal particles, etc. to perform centrifugal rotation. Since the density of iron filings, oxide scale, metal particles, etc. is greater than that of water, the centrifugal force they experience is also greater than that experienced by water. During the rotation, under the guidance of the concave structure on the surface of separation disc 422 and the guide plate 423, such heavy impurities are thrown onto the inner wall of separation cover 421. At the opening directly opposite the central water inlet 424 of separation disc 422, water with smaller centrifugal force during rotation will directly penetrate the filter layer 425 and enter the inner cavity of the clean water drain pipe 12 through the water inlet 424. It should be noted that the impurities thrown onto the inner wall of the separation hood 421 will be scraped off by the scraper 427 driven by the rotation of the separation disc 422, and then fall into the inner cavity of the diversion hopper 11; the impurity fragments are attracted by multiple electromagnetic blocks 82 arranged on the spiral insulating rod 81 and transported to the spiral blade 74 area; at the same time, in conjunction with the drive motor 72, the main shaft 73 and the spiral blade 74 are driven to rotate, and the iron filings, oxide scale, metal particles, etc. are output through the slag discharge pipe 6; After the water flows through the filter layer 425 into the pipeline, the fine impurities remaining in the water can be transported to the inner cavity of the fine particle sedimentation hopper by the adsorption effect of the spiral insulating rod 81 and the electromagnetic block 82. Finally, the treated water flows out from the clean water outlet 5, first enters the primary filter cartridge 9 for preliminary filtration, and then passes through the cartridge-type fine filter cartridge 10 for fine filtration, completing the full-process filtration treatment of the return water, thereby realizing the purification and recycling of the return water.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
