Description

Technical Field

[0001] The invention relates to the technical field of grille plates, and in particular to a novel grille plate and an operation control method thereof. Background Art

[0002] In today's environmental protection and water resource recycling field, sewage treatment technology plays a vital role, in which the efficiency of the pretreatment stage directly affects the effect of subsequent treatment steps and the overall treatment cost. As a classic pretreatment facility, the grid plate is widely used in various sewage treatment systems. Its main function is to initially intercept and remove larger suspended solids in sewage, such as leaves, fibers and plastic fragments, to protect subsequent treatment units from clogging and damage, while reducing the biological treatment load.

[0003] Traditional grille plates are usually made of metal or plastic, designed with parallel or staggered bar structures, and use fixed spacing to screen impurities of different sizes. Although such grille plates meet the basic functional requirements, a series of problems are exposed in actual applications, such as: 1. Difficulty in cleaning and maintenance: After long-term operation, a large amount of debris is easily accumulated between the bars, forming screen residue. Traditional grille plates often require manual cleaning on a regular basis, which is not only labor-intensive, but also has low cleaning efficiency and high maintenance costs. This problem is particularly prominent when dealing with sewage with high solid content. 2. Leakage phenomenon: During cleaning, the grille plate is missing and leakage will occur.

[0004] In view of this, a grid plate and an operation control method thereof are proposed. Summary of the invention

[0005] The object of the present invention is to provide a grid plate and an operation control method thereof, which can effectively solve the above technical problems.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A new type of grille plate includes a blocking part and a rotating shaft, wherein the blocking part includes a grille body and a baffle, one side of the grille body is connected to the rotating shaft, and the opposite side is connected to the baffle, the baffle is arranged in an arc shape, and its arc radius is equal to the movement radius of the end of the grille body when rotating, and the rotating shaft is arranged horizontally.

[0008] In a preferred embodiment, the rotating shaft is arranged above the water surface.

[0009] In a preferred embodiment, a first through hole is provided on the grille body, and a second through hole is provided on the baffle.

[0010] In a preferred embodiment, two blocking parts are provided and are symmetrically arranged relative to the rotation axis.

[0011] In a preferred embodiment, a movable component is provided on the grille body, and the movable component is provided on a side of the grille body close to the baffle. The movable component includes two supports, a mounting shaft, and a movable part. The two supports are respectively provided on both sides of the grille body, and both ends of the mounting shaft are respectively installed on one of the supports. The movable part includes a first plate body, a second plate body and a movable sleeve. The mounting shaft passes through the movable sleeve, and the first plate body and the second plate body are symmetrically arranged relative to the radial parallel plane of the movable sleeve to form an arch structure.

[0012] In a preferred embodiment, the movable member is provided in plurality.

[0013] In a preferred embodiment, the first plate body and the second plate body are configured as hollow structures inside so that they can float in water.

[0014] In a preferred embodiment, the support includes a seat body and a push block, the seat body is provided with a mounting hole, the hole wall of the mounting hole is provided with a guide groove, the guide is parallel to the axial direction of the mounting shaft, the push block is provided with a guide strip matching the guide groove, the push block is arranged in the mounting hole, the end of the mounting shaft is inserted into the mounting hole, the end face of the push block close to the rotating shaft has a first table surface and a second table surface, the height of the first table surface is higher than the height of the second table surface, an arc chamfer is provided between the first table surface and the second table surface, and the end of the mounting shaft is provided with a push rod, and the push rod moves between the first table surface and the second table surface during the rotation of the mounting shaft.

[0015] In a preferred embodiment, the end surface of the abutment block close to the rotating shaft also has a third table surface, the third table surface occupies half of the area of ​​the end surface of the abutment block, the first table surface and the second table surface occupy the other half of the area, and the third table surface is higher than the first table surface.

[0016] A novel grid plate operation control method is applied to the novel grid plate, comprising the steps of:

[0017] S1, controlling the rotation shaft to rotate so that the grille body is out of the water surface and the baffle is kept in the water;

[0018] S2, using a backwash pump and delivering cleaning water to the nozzle, using the nozzle to reversely flush the grille body, so that the screen residue flows into the screen residue groove on one side of the grille channel;

[0019] S3, during the flushing process, controlling the rotating shaft to rotate back and forth;

[0020] S4. After flushing is completed, the shaft is controlled to rotate so that the grille body enters the water.

[0021] Compared with the prior art, when a new type of grid plate of the present invention operates normally, the grid body rotates to nearly vertical, and the screen residue is intercepted by the grid plate. When the grid body needs to be cleaned, the grid body rotates to separate it from the water surface.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0032] Embodiment 1:

[0033] like Figures 1 to 5 As shown, a new type of grille plate includes a blocking portion and a rotating shaft 1, wherein the blocking portion includes a grille body 2 and a baffle 4, wherein one side of the grille body 2 is connected to the rotating shaft 1, and the opposite side is connected to the baffle 4, wherein the baffle 4 is arranged in an arc shape, and the arc radius thereof is equal to the movement radius of the end of the grille body 2 when rotating, and the rotating shaft 1 is arranged horizontally.

[0034] When a new type of grid plate of the present embodiment operates normally, the grid body 2 rotates to nearly vertical, and the screen residue is intercepted by the grid plate. When the grid body 2 needs to be cleaned, the grid body 2 rotates to separate it from the water surface. At this time, the baffle 4 on the edge of the grid body 2 blocks the water inlet to prevent the screen residue from leaking through. Then turn on the backwash pump 19, and the water flows from the bottom to the top of the grid body 2 to wash away the intercepted screen residue (located on the upper part of the grid body 2), and the screen residue flows into the screen residue groove 21 on one side of the grid channel to achieve the removal and collection of the screen residue. The screen residue is transported out after the water is squeezed out by a shaftless screw press. Thereby, a convenient cleaning process is achieved and the occurrence of leakage is avoided.

[0035] In order to facilitate maintenance, the rotating shaft 1 is arranged above the water surface.

[0036] The grille body 2 is provided with a first through hole 3, and the baffle plate 4 is provided with a second through hole 5 for passing water. The grille body 2 and the baffle plate 4 are not limited to the form of the through holes, and can also be arranged in a grid shape.

[0037] In order to realize rotation, two blocking parts are provided, which are symmetrically arranged relative to the rotating shaft 1.

[0038] Alternatively, in a setting state where rotation is not required, the second through hole 5 may not be provided on the baffle plate 4 located at the upper position, and the baffle plate 4 located at the upper position and the grille body 2 are only used to balance the forces on both sides of the rotating shaft 1 .

[0039] Furthermore, in order to improve the cleaning efficiency, a movable component is provided on the grille body 2, and the movable component is arranged on a side of the grille body 2 close to the baffle 4. The movable component includes two supports 6, a mounting shaft 14, and a movable part. The two supports 6 are respectively arranged on both sides of the grille body 2, and the two ends of the mounting shaft 14 are respectively installed on one of the supports 6. The movable part includes a first plate body 16, a second plate body 17 and a movable sleeve 18. The mounting shaft 14 passes through the movable sleeve 18, and the first plate body 16 and the second plate body 17 are symmetrically arranged relative to the radial parallel plane of the movable sleeve 18 to form an arch structure.

[0040] Under the above structural setting, when cleaning, the water flow impacts the first plate 16 and the second plate 17, so that the first plate 16 and the second plate 17 rotate around the installation shaft 14, and knock the grille body 2 during the rotation, so that the grille body 2 vibrates, which is more conducive to the removal of dirt on the grille body 2. Since the first plate 16 and the second plate 17 are symmetrically arranged with respect to the radial parallel plane of the movable sleeve 18 to form an arch structure, when the first plate 16 and the second plate 17 are impacted, since the first plate 16 and the second plate 17 are inclined, such an arrangement makes the first plate 16 and the second plate 17 receive a force parallel to the axial direction of the installation shaft 14 under the action of the water flow, which will cause the movable part to move along the installation shaft 14, thereby avoiding the movable part set in a fixed position from blocking the grille body 2 and forming a blind area for cleaning.

[0041] In order to further enhance the vibration effect, a plurality of movable parts are provided.

[0042] In order to prevent the first plate 16 and the second plate 17 from blocking the water flow through the grille body 2 when the grille body 2 is in the water, the first plate 16 and the second plate 17 are provided with hollow structures inside so that they can float in the water. After the first plate 16 and the second plate 17 float, there will be no obstruction to the water flow through the grille body 2.

[0043] Further, the support 6 includes a seat body 7 and a push-up block 9, the seat body 7 is provided with a mounting hole 8, the hole wall of the mounting hole 8 is provided with a guide groove, the guide is parallel to the axial direction of the mounting shaft 14, the push-up block 9 is provided with a guide strip 10 matching the guide groove, the push-up block 9 is arranged in the mounting hole 8, the end of the mounting shaft 14 is inserted into the mounting hole 8, the end face of the push-up block 9 close to the rotating shaft 1 has a first table surface 11 and a second table surface 12, the height of the first table surface 11 is higher than the height of the second table surface 12, an arc chamfer is provided between the first table surface 11 and the second table surface 12, and an push-up rod 15 is provided at the end of the mounting shaft 14, and the push-up rod 15 moves between the first table surface 11 and the second table surface 12 during the rotation of the mounting shaft 14. Under such a structural setting, the switching of the grille body 2 between the fixed state and the non-fixed state can be realized. When the grille body 2 is cleaned, the grille body 2 is in the non-fixed state, and when in the normal working state, the grille body 2 is in the fixed state. The non-fixed state refers to the state in which the abutting block 9 does not abut the side wall of the canal, and the fixed state refers to the state in which the abutting block 9 abuts against the side of the canal. During the rotation of the mounting shaft 14, the abutting rod 15 will move between the first table surface 11 and the second table surface 12. When located on the first table surface 11, the abutting rod abuts against the abutting block 9, so that the abutting block 9 abuts against the side wall of the canal. When the abutting rod 15 is located on the second table surface 12, the abutting block 9 does not abut against the side of the canal.

[0044] The rotation of the mounting shaft 14 is achieved by the gravity and buoyancy of the first plate body 16 and the second plate body 17 .

[0045] In order to limit the rotation range of the installation shaft 14, the end surface of the abutting block 9 close to the rotating shaft 1 also has a third table surface 13, the third table surface 13 occupies half of the area of ​​the end surface of the abutting block 9, the first table surface 11 and the second table surface 12 occupy the other half of the area, and the third table surface 13 is higher than the height of the first table surface 11. The setting of the third table surface 13 limits the rotation range of the installation shaft 14, because the setting of the third table surface 13 will hinder the movement of the abutting rod 15, and the abutting rod 15 cannot move to the position of the third table surface 13, so that the position of the installation shaft 14 can be limited.

[0046] Embodiment 2:

[0047] like Figures 1 to 6 As shown, a novel grid plate operation control method is applied to the novel grid plate described in Example 1, comprising the steps of:

[0048] S1, controlling the rotating shaft 1 to rotate so that the grille body 2 is out of the water surface and the baffle 4 is kept in the water;

[0049] S2, using the backwash pump 19 and delivering cleaning water to the nozzle 20, using the nozzle 20 to backwash the screen body 2, so that the screen residue flows into the screen residue groove 21 on one side of the screen channel;

[0050] S3, during the flushing process, controlling the rotating shaft 1 to rotate back and forth;

[0051] S4. After flushing is completed, the rotating shaft 1 is controlled to rotate so that the grill body 2 enters the water.
