Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a water pollution treatment device. Background Art

[0002] In sewage treatment, grids are often used, which are usually arranged in the first purification chamber when sewage is discharged into the treatment system. They are mainly used to intercept particulate suspended matter and floating objects in the sewage to prevent subsequent pipelines, pumps or treatment units from being blocked. This reduces the working pressure for the subsequent treatment links in the sewage treatment system, greatly reduces the labor intensity of the equipment in the subsequent treatment links, and improves the purification quality.

[0003] With the continuous interception of suspended matter or large particulate pollutants, the labor intensity of manual cleaning is high and the efficiency is low. Therefore, how to automatically clean the suspended matter or large particulate pollutants from the grid regularly and improve the cleaning efficiency is a problem to be solved in the current sewage treatment process. Summary of the Invention

[0004] To solve the above problems, the present invention provides a water pollution treatment device, including a grid chamber. A first grid and a second grid are arranged in the grid chamber. The first grid is horizontally fixed in the grid chamber, and the second grid is perpendicular to the first grid. The water inlet side of the grid chamber is connected to a water source. The first grid and the second grid filter and intercept the water source. A slag discharge port is arranged on the side of the second grid, and a slag discharge seat is connected to the slag discharge port. A driving component is arranged between the second grid and the slag discharge seat. The inner side surface of the slag discharge seat lies on the first grid. The second grid moves towards the slag discharge port, and drives the slag discharge seat to flip through the driving component, so that the pollutants intercepted in the first grid and the second grid are automatically discharged through the slag discharge port.

[0005] As a further preferred option, there are two symmetric second grids, two slag discharge ports, which are symmetrically arranged on both sides of the grid chamber, two slag discharge seats, which are symmetrically installed on the two slag discharge ports through hinges, and two symmetric driving components, and each group of driving components is correspondingly arranged between the second grid and the slag discharge seat on the same side.

[0006] As a further preference, the driving assembly includes a crank arm connected to one end of the second grille and a driving frame fixed to the end of the crank arm. The driving frame extends beyond the water inlet end of the grille chamber and is provided with a rack. A hinge shaft is provided on the slag discharge seat, and both ends of the hinge shaft are pivotally connected to the slag discharge opening. A gear is mounted on the hinge shaft, and the gear is on the same side as the rack. When the second grille moves towards the middle of the grille chamber, the rack moves away from the gear. When the second grille moves towards the slag discharge seat, the rack engages with the gear in advance, and the slag discharge seat is driven to turn laterally by the hinge shaft through the engagement relationship. A track is provided on the water outlet end of the grille chamber, and a tread wheel is mounted on the other end of the second grille. The tread wheel is in rolling contact within the track.

[0007] As a further preference, the driving assembly further includes a bidirectional screw fixed to the water outlet side of the grille chamber through a bearing seat. A threaded transmission seat is fixed to each end of the two second grilles, and the two threaded transmission seats are driven on the two reverse threads of the bidirectional screw. The driving assembly further includes a controller fixed to the grille chamber, and the driving assembly further includes a motor fixed to the grille chamber. One end of the bidirectional screw is connected to the motor. A timing module is provided in the controller. A group of limit switches are respectively installed between the two sides of the grille chamber and the two threaded transmission seats.

[0008] As a further preference, the slag discharge seat is an L-shaped bent plate. The first side of the slag discharge seat is located within the slag discharge opening, and the second side of the slag discharge seat lies on the top surface of the first grille.

[0009] As a further preference, the slag discharge seat is provided with percolation holes, and the percolation holes are distributed on the second side of the slag discharge seat. The second side lying on the top surface of the first grille enables the percolation holes to communicate with the leakage holes on the first grille up and down.

[0010] As a further preference, a lower discharge hopper is provided in the grille chamber at the bottom side of the first grille, and the lower discharge hopper slopes downward towards the water outlet side of the grille chamber.

[0011] As a further preference, a hopper is fixed to the surrounding surface of the grille chamber. Both ends of the hopper reach the bottom sides of the two slag discharge openings. A discharge pipe is provided in the middle of the hopper, and both ends of the hopper slope downward towards the middle of the hopper.

[0012] The beneficial effects of the present invention compared with the prior art are:

[0013] 1. A controller is provided on the grille compartment. A timing module is provided inside the controller. A first grille and a second grille are provided inside the grille compartment. The first grille is horizontal inside the compartment, and the second grille is vertical inside the compartment and located on the top surface of the first grille. One end is in a driving relationship with the slag discharge seat in the middle compartment of the cabin through a driving mechanism, and the other end is connected to a bidirectional screw through a threaded transmission seat. The bidirectional screw drives the second grille to move towards the slag discharge seat, pushing the pollutants intercepted in the cabin into the slag discharge seat. At the same time, through the driving relationship, the slag discharge seat is turned outwards, and the obtained pollutants are discharged outwards through the slag discharge port. The pollutants finally fall into the hopper and flow into the discharge pipe under the inclination of the hopper, realizing automatic discharging of the intercepted pollutants and improving the cleaning efficiency.

[0014] 2. In addition, there are two sets of cleaning functions symmetrically arranged on the grille compartment. The grille compartment serves as a primary cleaning device when sewage is injected. When sewage is injected, not only large-particle pollutants are intercepted and treated, reducing the labor intensity of the downstream purification device, but also through an automated cleaning method, the pollutants intercepted in the grille compartment are automatically cleaned. There are two sets of cleaning functions, left and right, inside the same grille compartment. Therefore, the cleaning efficiency can be improved. The left and right second grilles respectively clean the pollutants on the same side, that is, the pollutants intercepted in the grille compartment are divided into left and right parts, and then are respectively cleaned outwards by the left and right second grilles. In this way, the thrust when the second grille pushes the pollutants is smaller, so the thickness of the second grille is thinner, reducing costs. Correspondingly, the grille holes opened on them are shallower, which is conducive to sewage filtration when pushing the pollutants and improves the filtration efficiency.

Specific embodiments

[0023] The following will clearly and completely describe the above and other embodiments and advantages of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments.

[0024] In one embodiment, as Figures 1-7 shown:

[0025] This embodiment provides a water pollution treatment device, including a grille chamber 1. The grille chamber 1 is provided with a first grille 2 and a second grille 3. The first grille 2 is horizontally fixed in the grille chamber 1, and the second grille 3 is perpendicular to the first grille 2. The water inlet side of the grille chamber 1 is connected to a water source. The first grille 2 and the second grille 3 filter and intercept the water source. A slag discharge port 5 is provided on the side of the second grille 3. A slag discharge seat 6 is connected to the slag discharge port 5. A drive assembly 7 is provided between the second grille 3 and the slag discharge seat 6. The inner side surface of the slag discharge seat 6 rests on the first grille 2. The second grille 3 moves towards the slag discharge port 5 and drives the slag discharge seat 6 to flip through the drive assembly 7, so that the pollutants intercepted in the first grille 2 and the second grille 3 are automatically discharged through the slag discharge port 5.

[0026] As a further preference, there are two symmetric second grilles 3, two left and right slag discharge ports 5, and they are symmetrically opened on both sides of the grille chamber 1. There are two left and right slag discharge seats 6, and they are respectively symmetrically installed on the two slag discharge ports 5 through a hinge shaft 10. There are two symmetric drive assemblies 7, and each set of drive assemblies 7 is correspondingly arranged between the second grille 3 and the slag discharge seat 6 on the same side. When the left second grille 3 moves leftward, it will drive the left drive assembly 7, causing the left slag discharge seat 6 to flip outward. When the right second grille 3 moves rightward, it will drive the right drive assembly 7, causing the right slag discharge seat 6 to flip outward, and the pollutants intercepted in the grille chamber 1 are cleaned outward in a left-right symmetric and left-right divided manner.

[0027] As a further preferred embodiment, the driving assembly 7 includes a crank arm 8 connected to one end of the second grille 3 and a driving frame 9 fixed to the end of the crank arm 8, the driving frame 9 extends beyond the water inlet end of the grille compartment 1 and is equipped with a rack 12, a hinge shaft 10 is provided on the slag discharge seat 6, both ends of the hinge shaft 10 are transferred to the slag discharge port 5, a gear 11 is installed on the hinge shaft 10, the gear 11 and the rack 12 are on the same side end, when the second grille 3 moves toward the middle of the grille compartment 1, the rack 12 moves away from the gear 11, when the second grille 3 moves toward the slag discharge seat 6, the rack 12 engages with the gear 11 in advance, and the slag discharge seat 6 is driven to flip sideways by the hinge shaft 10 through the meshing relationship.

[0028] As a further preferred embodiment, the drive assembly 7 also includes a bidirectional screw 21 fixed to the water outlet side of the grille compartment 1 through a bearing seat, and a threaded transmission seat 15 is fixed to each end of the two second grilles 3. The two threaded transmission seats 15 are transmitted on two sections of reverse threads of the bidirectional screw 21. The drive assembly 7 also includes a controller 16 fixed to the grille compartment 1. The drive assembly 7 also includes a motor 17 fixed to the grille compartment 1, one end of the bidirectional screw 21 is connected to the motor 17, and a timing module is provided in the controller 16. A group of limit switches 18 are respectively installed on both sides of the grille compartment 1 and between the two threaded transmission seats 15.

[0029] As a further preferred embodiment, the slag discharge seat 6 is an L-shaped bent plate, a first side edge 61 of the slag discharge seat 6 is located in the slag discharge port 5 , and a second side edge 62 of the slag discharge seat 6 falls on the top surface of the first grid 2 .

[0030] As a further preferred embodiment, the slag discharge seat 6 is provided with seepage holes 63 , which are distributed on the second side 62 of the slag discharge seat 6 , and the second side 62 falls on the top surface of the first grid 2 so that the seepage holes 63 are connected with the leakage holes on the first grid 2 up and down.

[0031] As a further preference, a lower discharge hopper 4 is provided in the grille compartment 1 and is located at the bottom side of the first grille 2. The lower discharge hopper 4 is inclined downward toward the water outlet side of the grille compartment 1, and the inclined end of the lower discharge hopper 4 is connected to the offline water purification environment of the sewage treatment system, such as an offline sewage pool or sedimentation.

[0032] As a further preferred embodiment, a hopper 19 is fixed on the surrounding surface of the grid cabin 1, with both ends of the hopper 19 reaching the bottom sides of the two slag discharge ports 5, a discharge pipe 20 is provided in the middle of the hopper 19, and both ends of the hopper 19 are inclined downward toward the middle of the hopper 19.

[0033] Sewage enters the grille chamber 1 from the inlet side. After being intercepted by the first grille 2 and the second grille 3, large particulate pollutants (hereinafter collectively referred to as pollutants) are intercepted, and the sewage leaks into the lower discharge hopper 4 and finally discharges into the lower treatment environment. In the present invention, the pollutants are intercepted on the first grille 2, the second grille 3 and the slag discharge seat 6. The present invention can clean these pollutants outwards through the slag discharge seat 6 and the second grille 3. For example, the timing module in the controller 16 sets the motor 17 to start once every half hour. The motor 17 drives the bidirectional screw 21 to rotate. The upper sewage gate is automatically closed under the control of the controller 16. The bidirectional screw 21 drives the two threaded transmission seats 15 to move in opposite directions by using the threads on both sides that are opposite to each other. The two threaded transmission seats 15 respectively drive the left and right second grilles 3 to move in opposite directions along the grille chamber 1. The second grille 3 on the left moves towards the slag discharge seat 6 on the left, and the second grille 3 on the right moves towards the slag discharge seat 6 on the right. At the same time, the pollutants intercepted between it and the first grille 2 are pushed onto the second side 62 of the left and right slag discharge seats 6. Since the left and right drive frames 9 extend the two racks 12 towards the left and right sides in advance, before the left and right second grilles 3 completely move to the second side 62 of the two slag discharge seats 6, the two drive frames 9 will respectively engage the two racks 12 with the left and right gears 11 in advance. As the left and right second grilles 3 continue to move towards both sides, the left and right racks 12 will respectively engage the two gears 11 to rotate. The left and right gears 11 respectively drive the left and right hinge shafts 10 to rotate. The left and right hinge shafts 10 respectively drive the two slag discharge seats 6 to turn outwards from the slag discharge port 5. At this time, the second side 62 on the two slag discharge seats 6 turns upwards as shown in Figure 5 . The second grille 3 continues to move a certain distance, and the rack 12 continues to engage the gear 11 to rotate, increasing the turning amplitude of the slag discharge seat 6 until the pollutants obtained are discharged outwards through the slag discharge port 5 by using the dumping effect generated during its turning. The pollutants finally pour into the hopper 19 and flow into the discharge pipe 20 under the inclination of the hopper 19, and the intercepted pollutants complete automatic discharging. The purpose of the vertical setting of the second grille 3 is not only to have a material pushing effect, but also to have the same filtering and intercepting effect as the first grille 2 during the pushing process. At the same time, when pushing the pollutants, by making the pollutants displace on the first grille 2, the downward leakage speed of the residual sewage is accelerated, and the filtering efficiency is improved.

[0034] Continuing from the above, when the two screw drive seats 15 move towards the limit switch 18 on their respective sides, according to the control technology of the controller 16, the motor 17 stops rotating, the bidirectional screw 21 stops rotating, the two screw drive seats 15 stop moving, the rack 12 no longer meshes with the gear 11 to rotate, and the discharging of the two slag discharging seats 6 stops. For example, after the timing module reads the time for one minute, the controller 16 starts the motor 17 to reverse again. The motor 17 drives the bidirectional screw 21 to reverse, and the two screw drive seats 15 move towards each other. The two screw drive seats 15 drive the two second grilles 3 to move towards the middle of the grille chamber 1. The two drive frames 9 drive the two racks 12 away from the two gears 11 and, while moving away, mesh with the two gears 11 to rotate in reverse, so that the two slag discharging seats 6 return to the position as shown in Figure 1 (The second side 62 falls back onto the top surface of the first grille 2 again, and the first side 61 intercepts again at the slag discharging port 5. The grille chamber 1 of the present invention serves as a primary cleaning device when sewage is injected. When sewage is injected, not only large particle pollutants are intercepted and treated, reducing the labor intensity of the downstream purification device, but also through an automated cleaning method, the pollutants intercepted in the grille chamber 1 are automatically cleaned. Since two sets of cleaning functions are provided on the left and right in the same grille chamber 1, the cleaning efficiency can be improved. The two second grilles 3 on the left and right respectively clean the pollutants on the same side, that is, the pollutants intercepted in the grille chamber 1 are divided into two parts on the left and right, and then are respectively cleaned outwards by the two second grilles 3 on the left and right. In this way, the thrust when the second grille 3 pushes the pollutants is smaller, so the thickness of the second grille 3 is thinner, reducing the cost. Correspondingly, the grille holes opened on them are shallower, which is beneficial to sewage filtration when pushing the pollutants, improving the filtration efficiency.

[0035] As Figure 2 , Figure 3 shown, a track 13 is provided at the water outlet end of the grille chamber 1, and a tread wheel 14 is installed at the other end of the second grille 3. The tread wheel 14 rolls and contacts inside the track 13. When the two second grilles 3 on the left and right move, the tread wheels 14 at their water outlet ends roll along the track 13, ensuring the stability of the movement of the second grille 3. At the same time, the tread wheels 14 support on the track 13 and are close to the screw drive seat 15, which is equivalent to assisting the screw drive seat 15 to form a support point, preventing the gravity of the screw drive seat 15 from causing the bidirectional screw 21 to bend and deform, affecting the transmission.

[0036] It should be further noted that rubber plates or sealing plates are provided on the front and rear cavity walls of the grille chamber 1. When the first side 61 intercepts at the slag discharging port 5, its front and rear ends abut against the sealing plates to form a sealing effect, reducing water seepage when sewage enters.

[0037] It should be further noted that the bottom surface of the second grille 3 approaches the top surface of the first grille 2, that is, there is a gap for its movement between the bottom surface of the second grille 3 and the top surface of the first grille 2, or rollers are provided on the bottom surface of the second grille 3, and the rollers contact the top surface of the first grille 2 to increase the movement speed and avoid jamming.
