Description

Split orifice plate type grid dirt remover
Technical Field
The invention relates to the technical field of water treatment equipment, in particular to a split orifice plate type grid dirt remover.
Background
In a water treatment system, a grid is used as a key pretreatment unit for ensuring the stable operation of the system, and the main function of the grid is to remove impurities such as larger floaters, suspended matters and the like in sewage. According to the different intervals of the grid bars, the grids can be divided into coarse grids, fine grids and superfine grids, which are respectively used for intercepting suspended matters with different sizes so as to protect subsequent treatment facilities from being blocked or damaged. Specifically:
the coarse grid is used for intercepting large-volume suspended matters, wherein the spacing between the grid bars is 10-20 mm, so that the aeration systems of subsequent equipment such as pipelines, water pumps and grit chambers are not blocked.
And the distance between the fine grids is 5-10 mm, so that floating matters and suspended garbage in the sewage are further removed, and the stable operation of the sewage treatment system is maintained.
The superfine grid has the grid strip spacing of 1-2 mm, and is applied to a separation membrane or biological membrane process, so that the risk that membrane wires and fillers are blocked and wound by fine particles and fibers is reduced.
However, the conventional form of fine-grid and ultra-fine-grid decontaminating machine has the following significant problems:
The mesh is easy to be blocked, and for thin grids in the forms of internal inflow rotary type, rotary drum type and the like, although the grid slag leakage can be effectively reduced, suspended matters (such as inorganic particles, grease particles and fiber balls) are easy to be blocked on the surface due to the adoption of a grid mesh or pore plate structure, the suspended matters are difficult to be completely removed through gravity or high-pressure water flushing, and the overflow area is reduced and the grid resistance is increased due to long-term accumulation.
The interception efficiency is low, and for the grid in the form of the grid strips, although the short side spacing of the rectangular grid strips meets the design requirement, the long side spacing is larger than the grid strip spacing, so that the interception rate of strip-shaped impurities or fibers is low, and the filtering effect is influenced.
The common rotary rake type and rotary hole plate type fine gratings leak gate slag, and are difficult to fall onto a gate slag conveyor when turning back from a high position due to insufficient dead weight of intercepted impurities, so that partial impurities enter a subsequent channel along with water flow, and the overall interception efficiency is reduced.
In order to overcome the above problems, there are several designs of improved grid machines on the market, such as:
Patent CN217148596U proposes a grid machine with a telescopic structure, which can collect floats of different sizes by changing the mesh spacing by an adjusting mechanism, but the grid bars thereof are relatively fixed and lack effective grid slag cleaning equipment, so the effect of removing the grid slag is limited.
Patent CN210751593U describes a grating machine capable of filtering sewage, which realizes the distance adjustment by the combination of a movable plate and a fixed plate, but is more suitable for grating type filtration, and is difficult to efficiently intercept fine particles and fibers.
Patent CN208965511U describes a telescopic grille cleaning machine, which, although achieving grille pitch adjustment, is not efficient in cleaning due to inability to rotate.
Patent CN106430350a provides a curved surface grating cleaning machine, which uses a scraper to clean grating slag, but the problem of incomplete grating slag cleaning is also faced.
Based on the background, the invention aims to provide the split cleaning orifice plate type grid dirt remover, and solves the problems of blockage, low interception efficiency, grid residue leakage and the like in the prior art through the optimized orifice plate structural design and an efficient cleaning mechanism, so that the filtering performance and the maintenance convenience of the grid are improved.

The design of the closely attached plates ensures the close attachment between the first plate and the second plate, eliminates the problem that gaps possibly occur on the long sides of the plates, improves the interception effect on strip-shaped impurities or fibers, and enhances the overall filtering performance.
Reducing gate slag leakage
The separation type cleaning and conveying mechanism can accelerate the driving of the sheet to separate when the sheet reaches the lower part of the cleaning device, which is not only beneficial to cleaning, but also ensures that intercepted impurities smoothly fall onto the grid slag conveyor under the action of gravity, thereby avoiding the phenomenon of grid slag leakage caused by insufficient dead weight.

The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.
The application is further described in detail below with reference to fig. 1-8, and an embodiment of the application discloses a split orifice plate type grid dirt remover.
Referring to fig. 1 and 2, a split orifice plate type grill dirt removing machine includes a cabinet 100, a grill mechanism 200, a cleaning mechanism 300, and a conveying system.
The box body 100 comprises two symmetrically arranged parallelogram box plates 110, at least one fixing rod is arranged between the two box plates 110 to connect, and the fixing rods are used for connecting and fixing the two symmetrically arranged box plates 110 with each other. The side walls forming the parallelogram are respectively a bottom surface 160, an upstream surface 130, a top surface 140 and a downstream surface 150 which are sequentially connected, so that the box body 100 has higher structural strength and rigidity, can keep stable operation in a complex water treatment environment, and avoids the problem of faults caused by unstable structure of the traditional grid machine.
The grill mechanism 200 is designed to circulate around the bottom surface 160, the upstream surface 130, the top surface 140, and the downstream surface 150 of the housing 100, and specifically, when water flows in, it first contacts the upstream surface 130 of the housing plate 110, where the grill mechanism 200 begins to function, performing a preliminary filtration of the inflowing sewage. Sewage can smoothly enter the treatment area with minimum resistance, and the filtering efficiency is improved. Because the grid mechanism 200 continuously moves in the whole process, the sewage can be uniformly treated by utilizing the grid mechanisms 200 in different areas, the occurrence of local blocking phenomenon is avoided, and the filtering efficiency is improved.
The cleaning mechanism 300 is mounted on the top of the box body 100 and above the top surface 140 of the box plate 110, and when the grille mechanism 200 reaches the top surface 140, the cleaning mechanism 300 thoroughly cleans impurities attached to the surface of the grille mechanism 200, so that the grille mechanism 200 is always in a clean state, and high filtering performance is maintained
And a conveying system for driving the grill mechanism 200 to smoothly move along a predetermined path of the box board 110, ensuring that it reciprocates along the parallelogram circumference of the box board 110.
Referring to fig. 3 and 4, the grill mechanism 200 includes a plurality of first plates 210 and second plates 220 alternately arranged, and a plurality of filtering holes 240 are provided on the contact side wall of each plate. When the first plate 210 is spliced with the second plate 220, the corresponding filter holes 240 can be aligned with one another to form a complete filter channel. The filter holes 240 are semicircular openings with a diameter ranging from 1 to 5mm and the depth of the filter holes 240 ranging from 5 to 15mm. The design of the aperture can effectively intercept larger particle pollutants and ensure smooth water flow.
Wherein, the first plate 210 and the second plate 220 are both in a cube structure, and the cross sections of the width and the thickness are rectangular. The design not only ensures the close fit between the plates, but also provides convenience for installation.
When the water-facing surface 130 and the water surface have an included angle of 60 degrees, and the water flows through the water-facing surface in an internal inflow mode, the water flows in the middle filter holes 240 of the two parallel plates, and the inflow direction is perpendicular to the plane direction of the plates.
Referring to fig. 5 and 6, the surfaces of the first sheet 210 and the second sheet 220 are specially treated to be smooth, and contaminants are not easily attached. This helps to reduce the frequency of cleaning and extend the service life of the device. The first plate 210 and the second plate 220 preferably use a high molecular polymer or stainless steel as a plate material. The high molecular polymer has good corrosion resistance and ageing resistance, while the stainless steel has higher mechanical strength and wear resistance.
The opposite inner sidewalls of the two box boards 110 are respectively provided with a circular chute 120 for guiding the plurality of first plates 210 and second plates 220 to slide along a predetermined path. The design of the chute ensures the smoothness and accuracy of the sheet as it moves in circulation within the housing 100. The return chute 120 is circumferentially arranged along the parallelogram of the box plate 110 such that the first plate 210 and the second plate 220 pass through the bottom surface 160, the upstream surface 130, the top surface 140 and the downstream surface 150 in sequence during movement. This path design not only optimizes the water flow path, but also ensures that each plate is fully involved in the filtration process.
When the first plate 210 and the second plate 220 pass through the upstream surface 130, they are close to each other under the action of gravity, so as to ensure the uniformity of the diameters of the filtering holes 240. The design ensures the stability and reliability of the filtering channel, maintains higher filtering precision, and prevents the fluctuation of the filtering effect caused by the pore diameter change. If the filtering effect needs to be changed, only the first plate 210 and the second plate 220 with different pore sizes need to be replaced. The multifunction and the adjustability of the equipment are enhanced, and the requirements of different application scenes are met.
Referring to fig. 3 and 7, the transport system includes a transmission transport mechanism 400 and a purge transport mechanism 500:
The transmission conveying mechanism 400 is disposed at the lower part of the box 100, and is mainly used for driving the first plate 210 and the second plate 220 located on the back surface 150, the bottom surface 160 and the upstream surface 130 to move along the rectangular chute 120, so as to keep the first plate 210 and the second plate 220 tightly attached during the moving process, especially on the upstream surface 130, and ensure that the filter holes 240 are aligned to form a complete filter channel, thereby realizing efficient waste water filtration.
The cleaning and transporting mechanism 500 is disposed at the upper portion of the box 100, and is mainly used for driving the first plate 210 and the second plate 220 located at the corner of the upstream surface 130 near the top surface 140 and the corner of the top surface 140 to the upstream surface 150 to move. The main function of the cleaning mechanism is to accelerate and drive the plates to separate the first plate 210 from the second plate 220 when the plates pass through the top surface 140, so that the cleaning mechanism 300 can clean the impurities on the surfaces of the plates and between the plates efficiently.
The operation speed of the cleaning and conveying mechanism 500 is greater than that of the transmission and conveying mechanism 400, so that the first plate 210 and the second plate 220 can be separated in a short time, and impurities on the surfaces and among gaps of the plates can be thoroughly removed. The cleaning and conveying mechanism 500 enlarges the plate spacing to more than 3mm through acceleration driving, so that the cleaning mechanism 300 can easily enter gaps among plates to perform deep cleaning, dirt accumulation is effectively prevented, the service life of equipment is prolonged, the cleaning device can completely cover the plate surfaces and the gaps by the spacing of more than 3mm, each corner is ensured to be fully cleaned, and the generation of cleaning dead angles is avoided.
The reasonably controlled plate spacing ensures that the plate re-lamination cannot occur in the cleaning process, prevents the cleaned impurities from being attached to the surface of the plate again, and ensures the cleaning quality.
Wherein the linear velocity of movement of the cleaning conveyor 500 is 3-5 times the speed limit of the transmission conveyor 400. This differential speed design allows the high speed of the cleaning conveyor 500 to pull the sheets apart quickly as the sheets move from the upstream face 130 to the top face 140, creating sufficient clearance for the cleaning mechanism 300 to enter between the sheets for cleaning. Through quick separation, impurities on the surface of the plate and among gaps can be captured and removed by the cleaning device in a short time, so that the residual opportunity of pollutants is reduced, and the cleaning effect is ensured.
Referring to fig. 4 and 7, the transmission conveyor 400 includes two conveyor driving wheels 410 and two conveyor driven wheels 420, and a transmission chain 430 for driving the first sheet 210 and the second sheet 220 to move, the transmission chain 430 being used in cooperation with the conveyor driving wheels 410 and the conveyor driven wheels 420.
Two delivery driving wheels 410 are respectively arranged at the inner side of the connecting corner of the back surface 150 and the bottom surface 160 and at the upper part of the upstream surface 130. A driving motor is mounted on each of the conveyor driving wheels 410 for driving the conveyor driving wheels 410 to rotate, thereby driving the transmission chain 430 to reciprocate.
Two conveying followers 420 are provided on the inner side of the connecting corner of the upstream surface 130 and the bottom surface 160 and on the upper portion of the upstream surface 150, respectively. The primary purpose of the conveyor driven wheel 420 is to ensure that the transport path of the drive chain 430 is consistent with the return chute 120 in the housing 100, ensuring that the sheet does not deviate from the predetermined trajectory during movement.
The first plate 210 and the second plate 220 are respectively provided with a clamping groove 230, and a plurality of clamping blocks 250 are arranged on the outer side of the transmission chain 430, and the clamping blocks 250 correspond to the clamping grooves 230 on the first plate 210 and the second plate 220. When the transmission chain 430 rotates, the clamping block 250 is clamped in the clamping groove 230 of the plate, so as to drive the plate to move synchronously.
The design of the clamping blocks 250 and the clamping grooves 230 ensures the accurate positioning of the plate in the moving process, and avoids the risk of the plate shifting or falling off in the transporting process. The continuous movement of the drive chain 430 ensures smooth transport of the plates, particularly during transitions between the back surface 150, the bottom surface 160 and the upstream surface 130, a tight fit of the plates and stability of the filter holes 240.
When the conveyor driving wheel 410 is started, the transmission chain 430 starts to rotate, and first the first sheet 210 and the second sheet 220 after the washing are received from the upper portion of the side of the back surface 150. As the transmission chain 430 rotates, the clamping blocks 250 are gradually clamped in the clamping grooves 230 of the plate, and the transmission chain 430 carries the plate to move synchronously. The plates follow the path of the drive chain 430 through the bottom surface 160 of the housing 100 to the upstream face 130. When the upstream surface 130 moves, the first plate 210 and the second plate 220 are tightly attached due to gravity, so as to ensure that the filter holes 240 are aligned, and form a stable filter channel.
When the upstream surface 130 moves, gravity enables the plates to be attached naturally, so that additional power requirements are reduced, stability of the filter holes 240 is ensured, and filtering efficiency is improved. Through the supplementary laminating of gravity, reduced the required energy of actuating system, reduced the energy consumption of system, promoted whole efficiency.
When the first plate 210 and the second plate 220 reach the upper portion of the upstream surface 130, the clamping blocks 250 of the transmission chain 430 are separated from the clamping grooves 230 of the plates. At this time, the plate is pushed by the first plate 210 and the second plate 220 below the plate to move along the loop-shaped chute 120, and gradually approaches the cleaning and conveying mechanism 500.
The separation design of the clamping blocks 250 and the clamping grooves 230 ensures the seamless connection of the plates in different working areas, avoids the occurrence of clamping stagnation phenomenon and ensures the continuous operation of the system. After the plates are separated from the transmission chain 430, the plates can still move continuously by pushing the plates below, so that efficient transmission of the plates is ensured, and the whole cycle period is shortened.
Referring to fig. 4 and 7, the cleaning and conveying mechanism 500 includes two cleaning driving wheels 510 and two cleaning driven wheels 520, and a cleaning chain 530 for driving the first and second plates 210 and 220 to move, the cleaning chain 530 being used in cooperation with the cleaning driving wheels 510 and the cleaning driven wheels 520.
Two cleaning driving wheels 510 are respectively arranged on the inner side of the corner where the upstream surface 130 is connected with the top surface 140 and the inner side of the corner where the downstream surface 150 is connected with the top surface 140, and each cleaning driving wheel 510 is also provided with a driving motor for driving the cleaning driving wheel 510 to rotate, so as to drive the transmission chain 430 to reciprocate. By providing the cleaning drive wheels 510 on the upstream face 130 and the downstream face 150, respectively, a smooth transition of the plate between the different working areas is ensured. The independent driving motor can flexibly adjust the rotation speed according to the actual working condition, thereby ensuring the high efficiency and the stability of the cleaning process
The two cleaning driven wheels 520 are respectively disposed on the upper portion of the upstream surface 130 and the upstream surface 150, and the main function of the cleaning driven wheels 520 is to ensure that the transportation path of the transmission chain 430 is consistent with the return chute 120 in the case 100, so as to prevent the sheet from deviating from the predetermined track during the movement.
A plurality of clips 250 are also provided on the outer side of the cleaning chain 530, and the spacing between the clips 250 is greater than the spacing between the clips 250 on the driving chain 430. When the cleaning chain 530 rotates, the clamping blocks 250 are clamped in the clamping grooves 230 of the plates, so that the first plates 210 and the second plates 220 which are mutually spliced and contacted are separated. The larger spacing of the clips 250 enables the cleaning chain 530 to separate the first plate 210 from the second plate 220 in a shorter time, ensuring that the cleaning apparatus can efficiently clean impurities on the surfaces and between the gaps of the plates.
The rotational speed of the cleaning chain 530 is greater than the rotational speed of the drive chain 430, specifically 3-5 times. The speed difference design is used for ensuring that the plates can be quickly separated when entering the cleaning area, and the separation distance is kept enough in the cleaning process, so that the cleaning device can clean thoroughly. The faster speed of the cleaning chain 530 allows the plates to be pulled apart quickly as they enter the cleaning zone, creating sufficient clearance for the cleaning device to enter between the plates for cleaning. Through quick separation, impurities on the surface of the plate and among gaps can be captured and removed by the cleaning device in a short time, so that the residual opportunity of pollutants is reduced, and the cleaning effect is ensured.
When the washing drive wheel 510 is started, the washing chain 530 starts to rotate, first the upper part of the upstream surface 130 receives the first plate 210 and the second plate 220 detached from the drive chain 430. Because the rotation speed of the cleaning chain 530 is faster, when the clamping blocks 250 on the cleaning chain 530 are clamped in the clamping grooves 230 of the first plate 210, the next clamping blocks 250 with larger spacing are just clamped in the clamping grooves 230 of the second plate 220, so as to separate the first plate 210 from the second plate 220.
As the cleaning chain 530 continues to rotate, the carrying sheet is transported under the cleaning mechanism 300 to clean the first sheet 210 and the second sheet 220. After the cleaning, the cleaning chain 530 continues to move, transporting the cleaned first and second plates 210 and 220 to one side of the back surface 150, and disengaging at the upper portion of the back surface 150.
At this time, the first plate 210 and the second plate 220 slide along the loop-shaped chute 120 toward the transmission chain 430 under the action of gravity, and wait for the transmission chain 430 to be received for the next cycle.
Referring to fig. 1 and 8, the cleaning mechanism 300 includes a shower head 340 and a roller brush 350 and is equipped with a collection tank 310 and a screw conveyor 320.
The top of the box 100 is provided with an operation table 330, and the spray heads 340 and the rolling brushes 350 are fixedly arranged below the operation table 330. Wherein the spray head 340 is positioned in front of the rolling brush 350 in the driving direction of the driving chain 430. The primary function is to perform a preliminary water flow flush of the separated first and second plates 210, 220.
The spray head 340 firstly washes the first plate 210 and the second plate 220 by high-pressure water flow, so that most loose impurities on the surfaces of the plates can be removed quickly, and a good foundation is laid for cleaning the subsequent rolling brush 350. Through the water flow flushing, impurities on the surface of the plate are softened and loosened, so that friction force between the rolling brush 350 and the plate in the cleaning process is reduced, and the service life of the rolling brush 350 is prolonged. The high pressure water flow of the spray head 340 can cover the entire surface of the plate, ensure that every corner can be sufficiently washed, and improve the overall washing efficiency.
The roller brush 350 is located behind the spray head 340. The main function of the device is to clean the residual impurities on the first plate 210 and the second plate 220 washed by water flow in a rolling way. The rolling brush 350 can go deep into the surface and gaps of the plate through rotary motion, so as to remove stubborn dirt and attachments, and ensure that the surface of the plate is clean and has no residues.
And the pressure can be uniformly applied on the surface of the plate, so that the condition that partial cleaning is not thorough or excessive abrasion is avoided, and the consistency of cleaning quality is ensured. The rotation direction of the rolling brush 350 is opposite to the moving direction of the plate, so that the cleaned impurities can be effectively prevented from being attached to the surface of the plate again, and secondary pollution is avoided.
The collection box 310 is fixedly installed inside the box body 100 below the spray head 340 and the rolling brush 350. The main function is to collect impurities generated during cleaning and to clamp the first plate 210 and the second plate 220 therebetween, so as to prevent the impurities from splashing or scattering. By clamping the first plate 210 and the second plate 220 in the middle, the collection box 310 can effectively prevent impurities from entering other equipment components, avoid the risk of equipment damage, and prolong the service life of the equipment.
Screw conveyor 320 extends from the side wall of box 100 to the outside for conveying and discharging impurities in collection box 310. The main function of which is to transfer cleaned impurities from the tank 100 to an external treatment area.
The split orifice plate type grid dirt remover successfully solves the problems of easy blockage of meshes, low interception efficiency, grid slag leakage and the like in the prior art through the innovative structural design and the efficient cleaning mechanism.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
