Description

Technical Field

[0001] This invention relates to the field of bar screen cleaning technology, specifically to an online continuous cleaning device for bar screen filter elements. Background Technology

[0002] As a general-purpose filtration or interception element, bar screens are widely used in material separation processes in industries such as automated cleaning robots, wastewater treatment, industrial circulating water, and food processing. During use, various contaminants (such as fibers, particles, and viscous substances) inevitably adhere to and accumulate on the surface and pores of the bar screen, requiring regular cleaning to restore its permeability. However, existing cleaning technologies for bar screens have the following core drawbacks: 1. Poor continuity of cleaning operations: Existing cleaning methods mostly rely on manual offline cleaning or single-group bar screen shutdown for cleaning. The normal use of the bar screen must be interrupted during the cleaning process, resulting in low cleaning efficiency and the inability to synchronize production and cleaning. 2. Poor cleaning thoroughness: Existing methods such as high-pressure water washing and simple scraping can only remove the scum on the surface of the grid, but cannot remove the stubborn deposits embedded in the grid pores. The residue rate after cleaning is high, and the grid needs to be washed frequently. 3. The cleaning process is prone to secondary pollution: The lack of a structure for simultaneous treatment of stripped dirt means that the high moisture content filter residue after washing is very easy to fall back into the working environment, causing environmental pollution at the cleaning site, and the subsequent disposal cost of wet residue is high. 4. Poor stability of the cleaning actuator: low station switching accuracy, lack of self-locking limit, which easily leads to collision between the cleaning components and the grid, resulting in low equipment reliability. Summary of the Invention

[0003] The purpose of this invention is to provide an online continuous cleaning device for bar screen filter elements to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an online continuous cleaning device for bar screen filter elements, comprising: a collecting device, a slag removal device, and a cleaning device. The collecting device is capable of collecting the bar screen slag generated after stripping and cleaning. The slag removal device is disposed on the rear top surface of the collecting device near the right corner, and the slag removal device is capable of clamping and driving the bar screen filter element to be cleaned to achieve station transfer and pre-stripping of the filter slag. The cleaning device is disposed at the center of the rear top surface of the collecting device, and the cleaning device is capable of cooperating with the slag removal device to perform deep squeezing cleaning on the bar screen filter element transferred to the cleaning station, stripping off the attached filter slag, and squeezing and dewatering the stripped filter slag.

[0005] Preferably, the collection device includes: a first supporting platform, a sewage tank, a second supporting platform, a first electric push rod, a second electric push rod, a connecting plate, an electric slide, and a collection trough plate.

[0006] Preferably, the slag removal device includes: a support plate, a first drive assembly, a rectangular support rod, a rectangular electric push rod, a transmission plate, and an L-shaped grid. The support plate is located at the rear end of the top surface of the first bearing platform near the right corner; the first drive assembly is located at the top front side of the outer wall of the support plate; the rectangular support rod is located at the output end of the first drive assembly; there are four rectangular electric push rods, which are respectively located on the four sides of the front outer wall of the rectangular support rod; there are four transmission plates, which are respectively located at the pushing ends of the four rectangular electric push rods, and the four transmission plates are evenly distributed circumferentially; there are four L-shaped grids, which are respectively located on the front side of the outer wall of the four transmission plates, and the four L-shaped grids are evenly distributed circumferentially. Each L-shaped grid is embedded in the sewage tank through a rectangular electric push rod.

[0007] Preferably, the first driving assembly includes: an active dial, a brake motor, a lever, a support rod, a driven grooved wheel, a miniature electric push rod, and a locking block. The active dial is mounted on the top front side of the outer wall of the support plate via a first bearing; the brake motor is mounted on the top rear side of the outer wall of the support plate, and the output end of the brake motor is fixedly connected to the center of the rear side of the active dial; the lever is mounted on the outer wall of the active dial; the support rod is mounted on the front side of the outer wall of the support plate near the center; the driven grooved wheel is sleeved on the front end of the support rod via a second bearing, and each lever can be inserted into one of the four grooves opened in the driven grooved wheel. The center of the front side of the driven grooved wheel is fixedly connected to the rear end of the rectangular support rod; the miniature electric push rod is mounted on the center of the right front end of the outer wall of the support plate; and the locking block is mounted on the pushing end of the miniature electric push rod, and each locking block can be engaged in one of the four grooves opened in the driven grooved wheel.

[0008] Preferably, the rotation of the brake motor drives the active dial to rotate, and the active dial drives the lever to insert into a groove in the driven groove wheel. The brake motor drives the lever to rotate one revolution along its own axis, thereby driving the lever to drive the driven groove wheel to rotate 90 degrees, and driving all four L-shaped grilles to rotate 90 degrees.

[0009] Preferably, the cleaning device includes: an L-shaped support plate, a second electric push rod, an L-shaped carrier plate, a second drive assembly, and a comb-type squeezing cleaning plate. The L-shaped support plate is located at the center of the rear end of the top surface of the first carrier platform; the third electric push rod is located at the front end of the top inner wall of the L-shaped support plate; the L-shaped carrier plate is located at the pushing end of the third electric push rod; the second drive assembly is located at the center of one side of the inner wall of the L-shaped carrier plate; and the comb-type squeezing cleaning plate is located at the moving output end of the second drive assembly. Each of the comb-type squeezing cleaning plates is matched with four L-shaped grilles.

[0010] Preferably, the second drive assembly includes: a flat brake motor, an eccentric circular plate, a circular insert, a hollow elongated block, a reciprocating push rod, a limiting rod, and a moving groove. The flat brake motor is disposed at the center of one side of the inner wall of the L-shaped support plate; the eccentric circular plate is disposed at the output end of the flat brake motor; the circular insert is disposed at the eccentric end of the eccentric circular plate; the hollow elongated block is sleeved on the outer wall of the circular insert; the reciprocating push rod is disposed at the center of the bottom surface of the hollow elongated block; the limiting rod is disposed at the center of the bottom end of one side of the inner wall of the L-shaped support plate, and a through moving groove is provided at the right end of the top surface of the limiting rod, and the bottom end of the reciprocating push rod is sleeved in the moving groove, and the reciprocating push rod can be limited to move along the inner wall of the moving groove. The bottom end of the reciprocating push rod is connected and fixed to the center of the top surface of the comb-type extrusion cleaning plate.

[0011] Preferably, the flat brake motor can drive the eccentric circular plate to rotate, so that the eccentric circular plate drives the circular insert block to move within the hollow long block and limits the reciprocating push rod through the moving groove, thereby driving the reciprocating push rod to drive the comb-type extrusion cleaning plate to move back and forth in a limited linear motion.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a support plate as the first driving component to drive multiple L-shaped grids evenly distributed in a circle on a rectangular support rod to complete precise workstation indexing and flow. While a single L-shaped grid is embedded in the sewage tank to perform filtration, the remaining L-shaped grids to be cleaned can simultaneously complete the full-process cleaning operation at their corresponding workstations. This solves the industry pain points of traditional cleaning methods, which require offline operation and cannot synchronize cleaning and production. The cleaning process does not require interruption of the normal operation of the original filtration system. It can be adapted to the long-term continuous online cleaning needs of grid elements in various scenarios such as automated cleaning robots for filtration, sewage treatment, and industrial circulating water, greatly improving the automation level of cleaning operations and significantly improving the operating efficiency of cleaning operations and the overall production line.

[0013] 2. This invention uses a rectangular electric push rod in the slag removal device to drive a transmission plate, which in turn drives an L-shaped screen to perform small-amplitude, high-frequency reciprocating motions. This mechanically scrapes and pre-peeles loose scum and large debris adhering to the screen surface, eliminating interference from surface contaminants with subsequent deep cleaning. Then, a third electric push rod in the cleaning device, using an L-shaped support plate as its mounting base, drives an L-shaped support plate to achieve precise vertical feeding and positioning. This allows the comb-type extrusion cleaning plate, precisely matched to the pores of the L-shaped screen, to perform high-frequency reciprocating linear motion under the drive of the second drive component. The comb teeth repeatedly insert into the screen pores, thoroughly squeezing, peeling, and removing embedded, stubborn deposits that traditional cleaning methods cannot handle. This achieves full-range, no-dead-angle cleaning of the screen's filter surface and internal pores, fully restoring the filtration permeability of the screen elements, significantly reducing the frequency of screen rewashing, and extending its stable service life.

[0014] 3. This invention achieves closed-loop management of the entire cleaning process through the coordinated operation of the collection device, slag removal device, and cleaning device. The sludge removed during cleaning can be squeezed and dehydrated simultaneously by the cleaning device, significantly reducing the moisture content of the sludge. Then, through the first electric push rod and the second electric push rod in the collection device, which are based on the first bearing platform and installed on the second bearing platform, and connected to the electric slide table via the connecting plate, the collection tank plate and the L-shaped grid to be unloaded are precisely aligned through multi-dimensional linkage. This ensures that the dehydrated dry sludge is collected in a sealed manner in the collection tank plate throughout the process. This not only completely avoids secondary pollution caused by the scattering and falling of high moisture content sludge back into the working environment, but also simultaneously completes the volume reduction treatment of cleaning waste, greatly reducing the difficulty and operating cost of subsequent disposal of sludge after cleaning.

[0015] 4. This invention incorporates high-precision transmission and a double self-locking limit structure for both station switching and execution actions in cleaning operations. During station switching, the brake motor in the first drive assembly drives the active dial and lever to rotate the driven grooved wheel supported by the support rod, achieving precise indexing and rotation. This enables precise switching of the L-shaped grid station. After switching, a micro electric push rod drives a locking block to engage in the groove of the driven grooved wheel. Combined with the self-locking capability of the brake motor, this achieves double self-locking limit of the station, completely avoiding station offset, misalignment, and component collision damage during cleaning. During cleaning execution, the flat brake motor in the second drive assembly drives the eccentric circular plate to rotate. This, combined with the limited movement of the circular insert at the eccentric end within the hollow long block and the lateral limiting and guiding of the moving groove on the limit rod to the reciprocating push rod, precisely converts the rotational motion into a stable linear reciprocating motion of the comb-type extrusion cleaning plate connected to the bottom of the reciprocating push rod. This ensures smooth transmission and controllable action, significantly improving the stability and reliability of the cleaning device during long-term automated operation and effectively extending the overall service life of the equipment.

[0023] As a preferred option, further, such as Figure 6 and Figure 7As shown, the cleaning device 3 includes: an L-shaped support plate 31, a third electric push rod 32, an L-shaped bearing plate 33, a second drive assembly 34, and a comb-type extrusion cleaning plate 35. The L-shaped support plate 31 is located at the center of the rear end of the top surface of the first bearing platform 11; the third electric push rod 32 is located at the front end of the top surface of the inner wall of the L-shaped support plate 31, and the third electric push rod 32 has a certain load-bearing capacity and is used to drive the L-shaped bearing plate 33 to move up and down in a limited manner; the L-shaped bearing plate 33 is located on the third electric push rod 35.

[0024] As a preferred option, further, such as Figure 7 and Figure 8 As shown, the second drive assembly 34 includes: a flat brake motor 341, an eccentric circular plate 342, a circular insert 343, a hollow elongated block 344, a reciprocating push rod 345, a limiting rod 346, and a moving groove 347.

The moving groove 347 limits the reciprocating push rod 345, so that the reciprocating push rod 345 drives the comb-type extrusion cleaning plate 35 to move in a limited reciprocating linear motion. This second drive assembly 34, through the cooperation of the eccentric circular plate 342 and the moving groove 347, converts the rotational motion of the flat brake motor 341 into a stable and controllable linear reciprocating motion. With the self-locking and double limiting structure, it realizes uniform and efficient extrusion dewatering of screenings, and has the advantages of compact structure and reliable operation.

[0025] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows: The L-shaped bar screen 26 to be cleaned is designed to continuously intercept solid suspended matter and filter residue in the fluid at the working position of the fluid filtration system. As the operating time increases, a large amount of loose scum will adhere to the surface of the bar screen, and stubborn filter residue will be embedded in the pores of the bar screen, which can easily cause problems such as bar screen blockage, a sharp drop in filtration efficiency, and an increase in fluid resistance. Traditional cleaning methods often require offline processing after shutdown, which cannot achieve continuous online cleaning and seriously affects the continuous operating efficiency of the filtration system. This device adopts a four-station intermittent synchronous switching cleaning architecture. The first drive component 22 drives four sets of circumferentially distributed L-shaped grids 26 on the rectangular support rod 23 to complete a 90° precise indexing rotation, realizing continuous cyclic switching between the system filtration operation station, pre-cleaning station, deep cleaning station, and unloading and reset station. When one set of L-shaped grids 26 is performing the original filtration operation at the system filtration operation station, the other three sets of L-shaped grids 26 simultaneously complete the full-process cleaning operation at the corresponding station. The cleaning process does not interrupt the normal operation of the original filtration system at all, fundamentally solving the core defect of traditional cleaning methods that require machine shutdown and operation interruption.

[0026] Once the L-shaped screen 26 with attached filter residue is precisely transferred to the pre-cleaning station by the first drive assembly 22, the device initiates the pre-stripping and cleaning process: The L-shaped grille 26 is driven by the corresponding rectangular electric push rod 24, which drives the transmission plate 25 to complete the reset action of the L-shaped grille 26 to be cleaned, so that the entire filter surface of the L-shaped grille 26 is fully exposed to the cleaning operation surface, eliminating cleaning blind spots and providing a foundation for full-area cleaning. With the small-amplitude high-frequency reciprocating feed of the rectangular electric push rod 24, the L-shaped grid 26 is driven by the transmission plate 25 to complete the synchronous small-amplitude reciprocating motion, which mechanically scrapes and pre-peeles the loose scum and large debris attached to the surface of the L-shaped grid 26, completing the first cleaning process and eliminating surface interference for subsequent deep pore cleaning. The loose filter residue that has been pre-stripped falls directly into the sealed collection channel of the collection device 1 below, preventing the scum from falling back into the fluid and causing secondary pollution, while ensuring the effectiveness of subsequent deep cleaning operations.

[0027] The L-shaped grille 26, having completed pre-stripping and cleaning, is precisely rotated again by the first drive assembly 22 and transferred to the deep cleaning station. There, it is precisely aligned with the cleaning device 3, initiating the core deep cleaning process. First, the third electric push rod 32 installed on the L-shaped support plate 31 of the cleaning device 3 drives the L-shaped support plate 33 to complete the precise vertical feeding and positioning, so that the comb-type squeezing cleaning plate 35 below the L-shaped support plate 33 corresponds one-to-one with the grid gap of the L-shaped grid 26 to be cleaned, ensuring that the cleaning action can completely cover every gap of the grid without cleaning dead corners. The second drive assembly 34 is activated, and the eccentric circular plate 342 is driven to rotate by the flat brake motor 341 installed on the inner wall of the L-shaped support plate 33. This causes the circular insert block 343 at the eccentric end to complete the limited movement within the hollow long block 344. In conjunction with the lateral limit of the reciprocating push rod 345 by the moving groove 347 on the limit rod 346, the rotational motion of the flat brake motor 341 is precisely converted into the high-frequency limited reciprocating linear motion of the comb-type squeezing cleaning plate 35. During the reciprocating motion, the comb teeth of the comb-type squeezing cleaning plate 35 repeatedly insert into the grid gaps of the L-shaped grid 26, thoroughly squeezing, peeling, and removing stubborn filter residue embedded in the pores that cannot be removed by traditional high-pressure water washing and simple scraping, achieving a thorough cleaning of the L-shaped grid 26 filter surface and internal pores without dead angles, fundamentally solving the grid clogging problem. The filter residue removed by cleaning is guided throughout the entire process in a closed chamber. Through the reciprocating squeezing action driven by the same set of second drive components 34, the filter residue is squeezed and dehydrated simultaneously, which greatly reduces the moisture content of the filter residue. This not only avoids the high moisture content filter residue falling back into the fluid and causing secondary pollution, but also simultaneously completes the volume reduction treatment of cleaning waste, forming a closed-loop control of the entire cleaning process.

[0028] After completing the full-process deep cleaning, the L-shaped grille 26 is precisely rotated by the grooved wheel mechanism of the first drive assembly 22 and transferred to the unloading and reset station, whereby the device starts the cleaning and reset process: Through the multi-dimensional linkage drive structure of the collection device 1, the precise and sealed collection of the cleaning screen residue is achieved: the first bearing platform 11 and the second bearing platform 13 serve as installation supports, and the first electric push rod 14 and the second electric push rod 15 complete the forward and backward and vertical feed adjustment. The electric slide table 17 installed on the connecting plate 16 drives the collection trough plate 18 to complete the lateral displacement adjustment, so that the collection trough plate 18 and the L-shaped grid 26 at the unloading and reset station can complete synchronous tracking and alignment. The dry filter residue on the L-shaped grid 26 after cleaning, peeling and dewatering falls precisely and completely into the sealed collection trough plate 18 under the action of gravity, without any spillage or leakage, and completely completing the collection and disposal of cleaning waste. After completing unloading and full-process cleaning, the L-shaped bar screen 26 is precisely rotated again by the first drive component 22 and returns to the system filtration work station to cycle through the entire process of filtration and online cleaning, realizing long-term, stable, automated and continuous online cleaning and maintenance of the bar screen filter element.

[0029] The entire cleaning process of this device adopts a high-precision drive and limit structure design with self-locking function, which ensures the stability and controllability of the cleaning operation and is fully adapted to the long-term automated operation requirements of industrial scenarios. The brake motor 222 drives the active dial 221 to rotate, causing the lever 223 to insert into the groove of the driven groove wheel 225, driving the driven groove wheel 225 to complete a precise 90° indexing rotation, and simultaneously driving the four sets of L-shaped grids 26 to complete the workstation switching. After the workstation switching is completed, the micro electric push rod 226 drives the locking block 227 to lock into the corresponding groove of the driven groove wheel 225. With the self-locking capability of the brake motor 222, the workstation achieves double self-locking limit, completely avoiding problems such as workstation displacement, inaccurate cleaning alignment, and component collision damage during the cleaning process.
