Description

Technical Field

[0001] This invention belongs to the field of municipal road drainage technology, and specifically relates to a municipal road drainage filtration device. Background Technology

[0002] Municipal road drainage systems are an important component of urban infrastructure, playing a crucial role in timely rainwater discharge, runoff purification, and flood prevention. With the acceleration of urbanization and the continuous expansion of road areas, the filtration function of drainage systems has become particularly important. Currently, specialized municipal road drainage filtration devices are commonly used.

[0003] A municipal road drainage filtration device, disclosed in CN120486554A, includes a drainage well, a drainage pipe installed at the bottom of the side wall of the drainage well, a manhole cover detachably installed on the surface of the drainage well, multiple sets of parallel water guide channels on the surface of the manhole cover, a filter plate fixedly installed inside the drainage well, and an anti-clogging mechanism that cooperates with the water guide channels on the surface of the manhole cover. The anti-clogging mechanism includes a grid box, a positioning component, and an adjusting component. A crushing mechanism that cooperates with the filter plate is provided inside the drainage well. The crushing mechanism includes a cutting blade, a vertical telescopic component, and a horizontal rotating component. When the water guide channel is blocked, causing the road surface water depth to continuously increase, the relative position of the grid box and the water guide channel can be automatically adjusted by the cooperation of the positioning component and the adjusting component, thereby automatically clearing the water guide channel and effectively promoting the drainage of road surface water.

[0004] However, the municipal road drainage filtration device still has the problem of insufficient filtration efficiency in actual operation. Road rainwater often carries a large amount of debris such as leaves, plastic bags, and gravel. This static filter structure is prone to clogging, resulting in poor drainage. Especially during the rainy season, a large amount of mixture rushes into the drain outlet in a short period of time, which can easily cause the drainage system to collapse. Summary of the Invention

[0005] In view of this, the present invention provides a municipal road drainage filtration device, which achieves automation and high efficiency in municipal drainage filtration through the synergistic effect of a continuously rotating filter belt and a dynamic scraper structure. The elastic cleaning scraper ensures thorough removal of debris to avoid clogging, while the inverted V-shaped box and inclined collection structure optimize the drainage and solid-liquid separation path. The integrated drive and spray cleaning functions ensure the stability of the device during long-term operation, significantly improving filtration efficiency and maintenance convenience. It is especially suitable for urban road environments that require continuous treatment of large-volume drainage. At the same time, the movable scraper head facilitates replacement after wear, and the plastic material prevents damage to the filter belt.

[0006] To solve the above-mentioned technical problems, the present invention provides a municipal road drainage filtration device, including a filter box and a filter grid plate disposed thereon. The filter box has a drainage pipe at its drain end. The filter box contains a filtration mechanism for filtering municipal road drainage. The filtration mechanism includes drive rollers symmetrically rotatably connected to the four corners of the filter box's inner cavity. A filter belt is driven between the four drive rollers. A collection box is located on one side of the filter box. An opening on the collection box communicates with a drain outlet on the filter box. The bottom of the opening is inclined and has a sliding groove. A cleaning scraper is slidably connected within the sliding groove. The cleaning scraper contacts the filter surface of the filter belt through a scraping element. An elastic element is provided within the sliding groove to provide elastic support for the cleaning scraper. The lower end of the filter box has an inverted V-shaped structure, and one end of the filter box is also equipped with a drive component for synchronously driving the drive roller to rotate. That is, through the coordinated action of the continuously rotating filter belt and the dynamic scraping structure, the automation and high efficiency of municipal drainage filtration are realized. The elastic cleaning scraper ensures that debris is thoroughly removed to avoid clogging. The inverted V-shaped box and the inclined collection structure optimize the drainage and solid-liquid separation path, while the integrated drive and spray cleaning functions ensure the stability of the device in long-term operation, significantly improving filtration efficiency and maintenance convenience. It is especially suitable for urban road environments that need to continuously handle large flow of drainage. At the same time, the movable scraper head makes it easy to replace after wear, and the plastic material can prevent damage to the filter belt. The elastic element includes springs evenly distributed in the sliding groove, and the ends of the springs are fixedly connected to the cleaning scraper, thus providing elastic force.

[0007] The scraping component includes a scraper head that is movably inserted into the end of the cleaning scraper. The end of the scraper head contacts the filter surface of the filter belt. The scraper head is made of hard plastic, which allows for quick replacement of worn or clogged scraper heads, extending service life and ensuring scraping stability.

[0008] The filtration mechanism also includes a cover plate that is movably mounted on the collection box. The cover plate is equipped with a collection net bag, which is located inside the collection box. The feed end of the collection net bag is connected to the opening, which facilitates cleaning and replacement of the collection net bag and prevents debris from scattering and polluting the environment.

[0009] The liquid outlet of the collection box is connected to the drainage pipe through a connecting pipe. The bottom of the inner cavity of the collection box is set to slope downward from the outside to the inside, which avoids water accumulation in the collection box and optimizes the drainage path.

[0010] It also includes a cleaning component, which includes a diversion box located inside the collection box. The diversion box has evenly distributed high-pressure nozzles along its axis on the side near the filter belt. The air outlet of the high-pressure nozzles all face the collection box, that is, the residual debris is removed by spraying gas, reducing the frequency of manual cleaning.

[0011] The drive assembly includes pulleys located at the ends of the drive rollers. The four pulleys are connected by a transmission belt, which enables synchronous drive of multiple rollers through belt drive.

[0012] The drive assembly also includes a protective mounting cover located on the filter box near the pulley end. The transmission belt and pulley are both located inside the protective mounting cover, which protects the transmission components from foreign matter.

[0013] The drive assembly also includes a drive motor housed within a protective mounting cover. The output shaft of the drive motor is fixedly connected to one of the pulleys, thus enabling precise power transmission.

[0014] A folding baffle is installed between the cleaning scraper and the opening, which prevents scraped debris from splashing through a sealing structure.

[0015] The beneficial effects of the above-described technical solution of the present invention are as follows: 1. When municipal road drainage enters the device through the filter grid at the top of the filter box, the impurities carried by the water flow are first intercepted by the filter belt. This filter belt is continuously rotated by drive rollers symmetrically arranged at the four corners of the filter box cavity, ensuring that the filtration process is continuous. At the same time, the debris attached to the surface of the filter belt comes into contact with the scraper head at the end of the cleaning scraper during the movement. The scraper head, supported by the elasticity of the spring, always keeps close contact with the filter surface of the filter belt, scraping the debris into the opening of the collection box below, and finally sliding into the collection box. The filtered water flows through the filter belt, collects at the bottom of the inverted V-shaped structure at the bottom of the filter box, and is discharged through the drainage pipe. The residual liquid in the collection box... The device features an inward-sloping bottom design, allowing water to flow into the drainage pipe via a connecting pipe. The continuously rotating filter belt and dynamic scraping structure work together to automate and efficiently filter municipal drainage. The flexible cleaning scraper ensures thorough removal of debris, preventing blockages. The inverted V-shaped housing and inclined collection structure optimize the drainage and solid-liquid separation path. Integrated drive and spray cleaning functions ensure the device's stability during long-term operation, significantly improving filtration efficiency and maintenance convenience. It is particularly suitable for urban road environments requiring continuous processing of large volumes of drainage. The movable scraper head allows for easy replacement after wear, and the plastic material prevents damage to the filter belt.

[0016] 2. The scraper head, supported by the elastic spring, always stays in close contact with the filter surface of the filter belt, scraping the debris into the opening of the collection box below, and finally sliding into the collection net bag. The collection net bag then collects the debris. When cleaning is needed, simply lift the cover to pull out the collection net bag for cleaning, making it convenient for relevant personnel to clean.

[0017] 3. The external air pump is connected to the distribution box. The external air pump then distributes the air through the distribution box, and finally, multiple high-pressure nozzles spray high-pressure gas onto the filter belt to help remove residual debris in the filter belt pores and prevent residual debris in the filter belt pores from affecting the subsequent filtration efficiency.

[0018] 4. The drive motor drives one of the pulleys to rotate. When the pulley rotates, it drives all the pulleys to rotate synchronously through the transmission belt, thereby making the four drive rollers rotate synchronously, thus ensuring the smooth operation of the filter belt.

[0019] 5. The folded baffle between the cleaning scraper and the opening can help seal and guide debris to slide down in a specific direction, ensuring the smooth operation of its internal structure. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-5 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0023] This embodiment provides a municipal road drainage filtration device, such as... Figure 1-5The filter box 100 includes a filter box 100 and a filter grid 101 mounted thereon. The filter box 100 has a drain pipe 102 at its drain end, which facilitates connection to the municipal road network. The filter box 100 contains a filtration mechanism for filtering municipal road drainage. This mechanism includes drive rollers 200 symmetrically rotatably connected to the four corners of the filter box 100's inner cavity. A filter belt 201 is connected between the four drive rollers 200. A collection box 202 is located on one side of the filter box 100. The upper end of the collection box 202 is open, and the opening on the collection box 202 connects to the drain outlet on the filter box 100. The bottom of the opening is inclined and has a sliding groove 203, allowing the cleaning scraper 204 to be tilted, ensuring that impurities smoothly slide into the collection box 202. Inside the 02, a cleaning scraper 204 is slidably connected in the sliding groove 203. The cleaning scraper 204 contacts the filter surface of the filter belt 201 through the scraping component. The sliding groove 203 is provided with an elastic component to provide elastic support for the cleaning scraper 204. The lower end of the filter box 100 has an inverted V-shaped structure to facilitate the rapid discharge of liquid into the collection box 202. One end of the filter box 100 is also provided with a drive assembly for synchronously driving the drive roller 200 to rotate. The elastic component includes springs 205 evenly arranged in the sliding groove 203. The ends of the springs 205 are all fixedly connected to the cleaning scraper 204 in the drainage pipe 102. The scraping component includes a scraper head 206 movably inserted into the end of the cleaning scraper 204. The end of the scraper head 206 contacts the filter surface of the filter belt 201. The scraper head 206 is a hard plastic scraper head.

[0024] When municipal road drainage enters the device through the filter grid 101 at the top of the filter box 100, the impurities carried by the water flow are first intercepted by the filter belt 201. This filter belt 201 is continuously rotated by drive rollers 200 symmetrically arranged at the four corners of the filter box cavity, ensuring that the filtration process is continuous. At the same time, the debris attached to the surface of the filter belt 201 comes into contact with the scraper head 206 at the end of the cleaning scraper 204 during the movement. The scraper head 206, supported by the elasticity of the spring 205, always keeps close contact with the filter surface of the filter belt 201, scraping the debris into the opening of the collection box 202 below, and finally sliding into the collection box 202. The filtered water flows through the filter belt 201, collects at the bottom of the inverted V-shaped structure at the lower end of the filter box, and is discharged through the drainage pipe 100. The residual liquid in the collection box 202 flows to the drainage pipe through the connecting pipe 209 via the inward tilting design at the bottom. The continuous rotating filter belt 201 and the dynamic scraping structure work together to achieve automation and high efficiency in municipal drainage filtration. The flexible cleaning scraper 204 ensures that debris is thoroughly removed to avoid clogging. The inverted V-shaped box and the tilted collection structure optimize the drainage and solid-liquid separation path. The integrated drive and spray cleaning function ensure the stability of the device in long-term operation, significantly improving filtration efficiency and maintenance convenience. It is especially suitable for urban road environments that require continuous treatment of large flow of drainage. At the same time, the movable design of the scraper head 206 makes it easy to replace after wear, and the plastic material can prevent damage to the filter belt 201.

[0025] like Figure 1-5 As shown, the filtration mechanism also includes a cover plate 207 movably mounted on the collection box 202. The cover plate 207 is provided with a handle for easy lifting by the operator, so that the relevant personnel can remove the collection net 208 for cleaning. The collection net 208 is located inside the collection box 202. The feed end of the collection net 208 is connected to the opening. The liquid outlet end of the collection box 202 is connected to the drainage pipe 102 through the connecting pipe 209. The bottom of the inner cavity of the collection box 202 is inclined downward from the outside to the inside.

[0026] Under the elastic support of the spring 205, the scraper head 206 always stays close to the filter surface of the filter belt 201, scraping the debris into the opening of the collection box 202 below, and finally sliding into the collection net bag 208. The collection net bag 208 then collects the debris. When cleaning is needed, simply lift the cover plate 207 to pull out the collection net bag 208 for cleaning, which is convenient for relevant personnel to clean.

[0027] like Figure 2-5As shown, it also includes a cleaning component, which includes a diversion box 300 disposed in the collection box 202. The diversion box 300 has high-pressure nozzles 301 evenly distributed along its axis on the side near the filter belt 201. The air outlet of the high-pressure nozzles 301 all face the collection box 202, and airflow or water flow can be used to clean the filter holes of the filter belt 201 to ensure subsequent filtration efficiency.

[0028] An external air pump is connected to a distribution box 300. The external air pump then distributes the air through the distribution box 300, and finally, multiple high-pressure nozzles 301 spray high-pressure gas onto the filter belt 201 to help remove residual debris from the filter holes of the filter belt 201 and prevent the residual debris from affecting the subsequent filtration efficiency.

[0029] like Figure 1-4 As shown, the drive assembly includes a pulley 400 disposed at the end of the drive roller 200. The four pulleys 400 are connected by a transmission belt 401. The drive assembly also includes a protective mounting cover 402 disposed on the filter box 100 near one end of the pulley 400. The protective mounting cover 402 is rectangular and has an open structure on the side near the filter box 100. The transmission belt 401 and the pulleys 400 are both located inside the protective mounting cover 402, which serves to provide safety protection for the internal mechanism. The drive assembly also includes a drive motor 403 disposed inside the protective mounting cover 402. The output shaft of the drive motor 403 is fixedly connected to one of the pulleys 400.

[0030] The drive motor 403 drives one of the pulleys 400 to rotate. When the pulley 400 rotates, it drives all the pulleys 400 to rotate synchronously through the transmission belt 401, thereby making the four drive rollers 200 rotate synchronously, thus ensuring the smooth operation of the filter belt.

[0031] like Figure 2-5 As shown, a folding baffle 500 is provided between the cleaning scraper 204 and the opening. The folding baffle 500 can fold adaptively as it moves, thereby improving splash prevention.

[0032] The folding baffle 500 between the cleaning scraper 204 and the opening helps to seal and guide debris to slide down in a specific direction, ensuring the smooth operation of its internal structure.

[0033] The working principle of the municipal road drainage filtration device provided by the present invention is as follows: When municipal road drainage enters the device through the filter grid 101 at the top of the filter box 100, the impurities carried by the water flow are first intercepted by the filter belt 201. The filter belt 201 is continuously rotated by drive rollers 200 symmetrically arranged at the four corners of the filter box cavity to ensure continuous filtration. At the same time, the debris attached to the surface of the filter belt 201 comes into contact with the scraper head 206 at the end of the cleaning scraper 204 during the movement. The scraper head 206, under the elastic support of the spring 205, always keeps close to the filter surface of the filter belt 201, scraping the debris into the opening of the collection box 202 below, and finally sliding into the collection net bag 208. The filtered water flows through the filter belt 201, collects at the bottom of the inverted V-shaped structure at the bottom of the filter box, and is discharged through the drainage pipe 100. The residual liquid in the collection box 202 flows to the drainage pipe through the connecting pipe 209 through the inward tilting design at the bottom. When cleaning is required, the diversion box 300, connected to an external air pump, sprays high-pressure gas onto the filter belt 201 through a high-pressure nozzle 301, thereby assisting in removing residual debris from the filter holes of the filter belt 201. At the same time, the drive assembly, driven by the drive motor 403, drives the pulley 400 and the transmission belt 401 to rotate all drive rollers synchronously, ensuring smooth operation of the filter belt. In addition, the folding baffle 500 between the cleaning scraper 204 and the opening can help seal and guide debris to slide down in a directional manner. Through the synergistic effect of the continuously rotating filter belt 201 and the dynamic scraping structure, the automation and high efficiency of municipal drainage filtration are achieved. The elastic cleaning scraper 204 ensures that debris is thoroughly removed to avoid clogging. The inverted V-shaped box and the inclined collection structure optimize the drainage and solid-liquid separation path, while the integrated drive and spray cleaning functions ensure the stability of the device in long-term operation, significantly improving filtration efficiency and maintenance convenience, especially suitable for urban road environments that require continuous treatment of large-volume drainage.

[0034] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0035] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
