Description

Technical Field

[0001] The invention relates to water surface cleaning equipment, in particular to grid slag scooping equipment. Background Art

[0002] The screen is one of the main auxiliary equipment in sewage treatment. It is generally composed of a group of parallel bars. By restricting the suspended solids in the sewage, the naturally flowing sewage automatically discards the suspended solids, thereby achieving solid-liquid separation of sewage and preventing the suspended solids from clogging or damaging the subsequent sewage treatment system or water pump.

[0003] Since the suspended matter on the screen will gradually increase, thus affecting the use effect of the screen, the screen needs to be cleaned. According to the cleaning method, the screen can be divided into manual cleaning screen and mechanical cleaning screen. The manual cleaning screen is suitable for small-scale sewage treatment, and the workers remove the garbage on the screen, which has low efficiency and high labor costs.

[0004] Existing mechanical slag cleaning grates scrape suspended matter off the grates by driving rake teeth to rotate along the grates, generating relative motion. Because the grates are typically tilted and the rake teeth need to rotate around the tilted grates, existing mechanical slag cleaning grates are complex in structure and require a large footprint. Their application range and performance are easily affected by the operating environment, resulting in limited applicability. Furthermore, the high water content of suspended matter during removal often causes the picked-up matter to flow out of the rake teeth along with the water flow, compromising the cleaning effect.

[0051] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0052] like Figures 1 to 7As shown, a screen slag scooping device 100 according to an embodiment of the present invention defines a direction perpendicular to the water flow direction as a first direction X, which includes a frame 1, a screen assembly 2, a slag scooping assembly 3, a cleaning assembly 4, a driving assembly 5 and a collecting basket (not shown in the figure); a water flow channel 10 for water flow is opened in the frame 1, the screen assembly 2 is arranged in the water flow channel 10, and the screen assembly 2 includes a plurality of vertically arranged screen bars 21, and the plurality of screen bars 21 are evenly spaced along the first direction X. are fixedly connected to the frame 1; the slag scooping assembly 3 includes rake teeth 31 and a rotary mechanism 32. The rake teeth 31 are arranged in front of the grille assembly 2 and are located in the water flow channel 10. The width of the rake teeth 31 is smaller than the gaps between adjacent grille bars 21. The rotary mechanism 32 is connected to the frame 1 and is used to drive the rake teeth 31 to rotate in the vertical direction. The rake teeth 31 can be inserted into the gaps between the grille bars 21 during the rotational movement to scoop up suspended matter blocked by the grille bars 21.

[0053] The cleaning assembly 4 includes a cleaning plate 41 and a baffle mechanism. The cleaning plate 41 is rotatably connected to the frame 1. The cleaning plate 41 is provided with cleaning teeth 411 extending toward the grille assembly 2. The cleaning teeth 411 match the shape of the rake teeth 31 and are arranged on the travel path of the rake teeth 31. The baffle mechanism is provided above the grille assembly 2 and connected to the cleaning plate 41. The baffle mechanism has a receiving position 4210.

[0054] The cleaning assembly 4 is switchable between a vertical state and an inclined state. When the rake teeth 31 are in contact with the cleaning teeth 411, the cleaning assembly 4 is in an inclined state, and the receiving portion faces the cleaning teeth 411 and receives the suspended matter scraped from the rake teeth 31 by the cleaning teeth 411. When the rake teeth 31 are separated from the cleaning teeth 411, the cleaning assembly 4 is in a vertical state, and the receiving portion 4210 faces away from the cleaning teeth 411. The collection basket (not shown) is correspondingly provided at the rear lower side of the baffle mechanism.

[0055] The driving assembly 5 includes a motor 51 ; the motor 51 is mounted on the frame 1 , and the output end of the motor 51 is connected to the input end of the rotary mechanism 32 , and the motor 51 is used to drive the rotary mechanism 32 to move.

[0056] Based on the above technical solution, the grid slag scooping equipment 100 is usually placed at the water inlet of water conservancy facilities such as rivers and box culverts. The water flows through the frame 1 through the water flow channel 10. The suspended matter carried in the water flow is blocked by the multiple grid bars 21 and stays in front of the grid bar 21 or in the gap between the adjacent grid bars 21; the motor 51 drives the rotary mechanism 32 to drive the rake teeth 31 to rotate in the vertical direction. The rake teeth 31 scoop up the suspended matter between the multiple vertically arranged grid bars 21 from bottom to top through the rotary movement. When it rises to the top of the grid assembly 2, it is connected with the rake teeth 31. The cleaning teeth 411 on the travel path generate relative motion, and the cleaning teeth 411 scrape suspended matter off the rake teeth 31; and the rake teeth 31 are connected with the cleaning teeth 411, so that the cleaning assembly 4 is in an inclined state, and the receiving position faces the cleaning teeth 411 and receives the suspended matter scraped off the rake teeth 31 by the cleaning teeth 411; when the rake teeth 31 continue to rotate and separate from the cleaning teeth 411, the cleaning assembly 4 is in a vertical state, and the receiving position faces away from the cleaning teeth 411, so that the suspended matter on the receiving position falls due to its own weight into the collection basket provided at the rear lower side of the baffle mechanism;

[0057] The purpose of removing suspended matter from the grille is thereby achieved; the rake teeth 31 rotate in the vertical direction, which is different from the rake tooth mechanism in the prior art that rotates by attaching to an inclined grille. This simplifies the structure of the grille slag scooping device 100, and the vertical arrangement of the grille bars 21 further reduces the footprint of the grille slag scooping device 100, facilitating its application in a variety of environments and providing high applicability. In addition, the tooth width of the rake teeth 31 is smaller than the gaps between adjacent grille bars 21, so that when the rake teeth 31 scoop up suspended matter, water automatically flows away from the rake teeth 31 and the grille bars 21. This results in the suspended matter picked up by the rake teeth 31 having a low water content, and the suspended matter will not flow away from the rake teeth 31 with the water after being scooped up, thereby improving the effect of removing suspended matter.

[0058] Preferably, the collection basket in the embodiment of the present invention is a common basket in the prior art, which is easy to obtain and has low cost; in some other embodiments, the collection basket can be a collection bucket of common transportation equipment such as a conveyor, so as to facilitate the transportation of suspended matter in combination with the transportation equipment.

[0059] Furthermore, if Figure 1 As shown, the frame 1 includes a connecting frame 11 and two frames 12; the two frames 12 are arranged in parallel along the first direction X and are connected by the connecting frame 11; thus, the water flow channel 10 is defined by the gap between the two frames 12, so that the structure of the grid slag scooping equipment 100 is relatively simple and easy to produce and process.

[0060] Preferably, if Figure 1 As shown, the outer contour of the frame 12 is square, which makes it easy to vertically place the entire device when the grid slag scooping device 100 is installed. At the same time, the square outer contour of the frame 12 facilitates calibration during placement to ensure that the entire device is vertically installed to the required position.

Then, by connecting the two ends of the rake teeth 31 to one of the chain links of the two plate chains 3233 and arranging the rake teeth 31 parallel to the first direction X, the rake teeth 31 continuously scoop up suspended matter from the gaps between the grille bars 21.

[0066] The first connecting shaft 321 and the second connecting shaft 322 are respectively rotatably provided through the covering portion 324 to ensure that the first connecting shaft 321 and the second connecting shaft 322 can rotate normally.

[0067] Preferably, if Figure 2 As shown, the covering portion 324 includes a decorative plate 3241 and a plurality of plate chain baffles 3242; the plurality of plate chain baffles 3242 are stacked in sequence and respectively connected to each link of the plate chain 3233 to form an elongated ring having a cross-sectional shape similar to that of the plate chain 3233; the cross-sectional shape of the decorative plate 3241 is an elongated ring, and the decorative plate 3241 is arranged in the elongated ring formed by the plurality of plate chain baffles 3242, and the decorative plate 3241 is connected to the inner surface of the frame 12; the decorative plate 3241 and the plurality of plate chain baffles 3242 jointly cover the opening of the rotary chamber 120 to protect the driving portion 323 located inside the rotary chamber 120.

[0070] Furthermore, if Figure 5 As shown, in order to facilitate the installation and mounting of the motor 51, so as to improve the protection of the motor 51 and thus improve the service life of the motor 51; the drive assembly 5 includes a motor water tank 52, and the motor water tank 52 is fixedly connected to the frame 12; an installation cavity 520 is opened in the motor water tank 52; the motor 51 includes a shell 511 and a main shaft 512, the shell 511 is fixed in the installation cavity 520, and the main shaft 512 extends along the first direction X and is transmission-connected to the first connecting shaft 321.

[0071] Furthermore, if Figure 4 As shown, the grid slag scooping equipment 100 also includes a transmission assembly 6, which includes a first extension shaft 61, a first transmission wheel 62, a second transmission wheel 63, and a transmission chain 64. One end of the first extension shaft 61 is fixedly connected to the first connecting shaft 321 and extends outward along the first direction X.

[0075] Furthermore, if Figure 2 and Figure 7As shown, the baffle mechanism includes a movable baffle 421 and a linkage part 422; the receiving position 4210 is provided on the side of the movable baffle 421 away from the cleaning plate 41; the bottom of the movable baffle 421 is hinged to the top of the grille assembly 2; the linkage part 422 includes a first linkage rod 4221 and a second linkage rod 4222; the first linkage rod 4221 is fixed on the side surface of the movable baffle 421 away from the cleaning plate 41, and extends away from the movable baffle 421 along the direction of water flow; the two ends of the second linkage rod 4222 are respectively hinged to the first linkage rod 4221 and the connecting member 43. Thus, when the rake teeth 31 are connected with the cleaning teeth 411, the cleaning plate 41 is driven to rotate, and the movable baffle 421 is driven by the first linkage rod 4221 and the second linkage rod 4222 to rotate, so that the receiving position 4210 is directed toward the cleaning teeth 411 and receives the suspended matter scraped from the rake teeth 31 by the cleaning teeth 411; when the rake teeth 31 are separated from the cleaning teeth 411, the cleaning plate 41 rotates in the opposite direction along the original path, thereby driving the movable baffle 421 to return to its original position, and the suspended matter on the receiving position 4210 falls into the collection basket by its own gravity.

[0076] Preferably, if Figure 2 and Figure 7 As shown, the movable baffle 421 is provided with the linkage parts 422 on both sides in the first direction, so that the movable baffle 421 can be effectively driven by the two linkage parts 422 .

[0077] Preferably, if Figure 2 and Figure 7 As shown, an extension piece 431 is fixed on the connecting piece 43, and the extension piece 431 is extended toward the movable baffle 421. The end of the second linkage rod 4222 away from the first linkage rod is hinged to the end of the extension piece 431 close to the movable baffle 421; the extension setting of the extension piece 431 facilitates the hinge of the second linkage rod 4222.

[0078] Preferably, if Figure 2 and Figure 7 As shown, the receiving position 4210 is an inclined surface arranged from top to bottom on the side of the movable baffle 421 away from the cleaning plate 41; the inclined surface can facilitate the suspended matter to fall into the collection basket by its own gravity when the cleaning component 4 is in a vertical state.

[0079] Preferably, if Figures 2 to 4 As shown, the front end of the cross section of the rake teeth 31 is in an upwardly curved shape, so as to facilitate the scooping of suspended matter and prevent the suspended matter from falling off the rake teeth 31 after being scooped, thereby ensuring the slag cleaning effect of the grid slag scooping equipment.

[0080] The working process of the present invention is as follows: the water pump is started to pump water and transport it to the installation cavity 520, so that the low liquid level switch is turned on, and the motor 51 is started; when the motor 51 is started, the main shaft 512 of the motor 51 rotates, driving the second transmission wheel 63 to rotate, and driving the first transmission wheel 62 to rotate through the transmission chain 64, and then driving the first connecting shaft 321 to rotate, so that the two active sprockets 3231 fixedly connected to the two ends of the first connecting shaft 321 rotate, thereby driving the plate chain 3233 connected to the active sprocket 3231 to rotate, and the chain links on the plate chain 3233 will rotate in the vertical direction with the rotation of the plate chain 3233, and then drive the rake teeth 31 to rotate. During the rotation of the rake teeth 31, the rake teeth 31 are inserted into the gaps between the grille bars and pick up the suspended matter on the grille bars from bottom to top. When the rake teeth 31 move to the grille group When the rake teeth 31 are above the cleaning member 2, the cleaning teeth 411 move relative to each other, and the cleaning teeth 411 scrape off the suspended matter on the rake teeth 31; and the relative movement of the rake teeth 31 and the cleaning teeth 411 causes the cleaning plate 41 to rotate, and the movable baffle 421 is rotated through the first linkage rod 4221 and the second linkage rod 4222, so that the movable baffle 421 rotates and tilts, and then the receiving position 4210 is directed toward the cleaning teeth 411, so that the scraped suspended matter falls onto the receiving position 4210; when the rake teeth 31 continue to move and separate from the cleaning teeth 411, the cleaning plate 41 rotates in the opposite direction to return to the initial position, and then drives the movable baffle 421 to rotate and restore to verticality, and the suspended matter on the receiving position 4210 falls into the collection basket below the rear side of the baffle mechanism under the action of its own gravity, thereby achieving the purpose of removing suspended matter.

[0081] In summary, the embodiment of the present invention provides a grid slag scooping device 100, which includes a frame 1, a grid assembly 2, a slag scooping assembly 3, a cleaning assembly 4, a driving assembly 5 and a collecting basket; the grid slag scooping device 100 is usually placed at the water inlet of water conservancy facilities such as rivers and box culverts, and water flows through the frame 1 via the water flow channel 10. The suspended matter carried in the water flow is blocked by a plurality of grid bars 21 and stays in front of the grid bar 21 or in the gap between adjacent grid bars 21; the motor 51 drives the rotary mechanism 32 to drive the rake teeth 31 to rotate in the vertical direction, and the rake teeth 31 scoop up the suspended matter between the plurality of vertically arranged grid bars 21 from bottom to top through the rotary motion, and when it rises to the top of the grid assembly 2, it generates relative motion with the cleaning teeth 411 located on the travel path of the rake teeth 31, and the cleaning teeth 411 scrapes the suspended matter off the rake teeth 31; and the rake teeth 31 and The connection of the cleaning teeth 411 makes the cleaning component 4 in an inclined state, and the receiving position faces the cleaning teeth 411 and receives the suspended matter scraped off the rake teeth 31 by the cleaning teeth 411; when the rake teeth 31 continue to rotate and separate from the cleaning teeth 411, the cleaning component 4 is in a vertical state, and the receiving position faces away from the cleaning teeth 411, so that the suspended matter on the receiving position falls due to its own weight into the collection basket provided at the rear lower side of the baffle mechanism; thereby achieving the purpose of clearing the suspended matter in the grille; the rake teeth 31 rotate in the vertical direction, which is different from the rake tooth mechanism in the prior art that rotates by relying on the inclined grille, simplifies the structure of the grille slag scooping equipment 100, and the grille bars 21 are vertically arranged, which further reduces the footprint of the grille slag scooping equipment 100, facilitates the application of the grille slag scooping equipment 100 in a variety of environments, and has high applicability. In addition, the tooth width of the rake teeth 31 is smaller than the gap between adjacent grille bars 21, so that when the rake teeth 31 are picking up suspended matter, water automatically flows away from between the rake teeth 31 and the grille bars 21, so that the suspended matter picked up by the rake teeth 31 has less water content, and the suspended matter will not flow away from the rake teeth 31 with the water after being picked up, thereby improving the effect of removing suspended matter.

It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
