Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, and in particular to an odor-removing and anti-clogging inner flow grille device. Background Art

[0002] An internal inlet screen is a type of pre-pump filtration commonly used in sewage treatment plants. Sewage flows in through the center of the screen and is discharged outward through mesh panels on either side. This traps debris inside the mesh panels, preventing it from entering the pump and potentially clogging it (especially hair and fiber, which can easily entangle the pump shaft). Consequently, debris trapped inside the mesh panels must be promptly removed to maintain their filtering effectiveness.

[0003] However, the water flushing method used in the existing technology has a poor cleaning effect, especially for filamentous debris (such as hair and fibers) inserted into the holes of the mesh plate, which is difficult to remove. In addition, these filamentous debris are prone to clinging to other dirt. If they remain in the holes of the mesh plate for a long time, they are likely to cause odor and hinder the flow of water through the mesh plate. Summary of the Invention

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the examples and accompanying drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0034] An internal inlet screen is a type of pre-pump filtration device commonly used in sewage treatment plants. Sewage flows in through the center of the screen and is discharged outward through mesh panels on either side. This traps debris inside the mesh panels, preventing it from entering the subsequent pump and potentially clogging it or even the pipeline (especially hair and fiber, which can easily entangle the pump shaft). Consequently, debris trapped inside the mesh panels needs to be promptly removed to maintain their filtering effectiveness.

[0035] The inner intake grille typically consists of multiple mesh panels arranged in an array along a chain drive path, rotating along the chain drive's path. Prior art typically incorporates guide grooves on the inner side of the inner intake grille. When the mesh panels reach the top, facing downward, debris trapped inside the panels falls into the guide grooves under the action of gravity and is discharged. However, relying solely on the gravity of debris will have a poor cleaning effect. For this reason, there is also a method of using water flow to flush the mesh plate and forcibly remove the debris intercepted on the inside of the mesh plate (using a flat nozzle to generate a strip of water flow, and the length direction of the strip of water flow is perpendicular to the upward direction of the mesh plate). However, this water flow flushing method can only flush the passing mesh plate once, and the flushing effect is poor. In addition, this water flow flushing method is difficult to remove filamentous debris (such as hair and fiber) inserted into the holes of the mesh plate; moreover, these filamentous debris are also easy to attach other dirt (especially organic matter). If they remain in the holes of the mesh plate for a long time, they are likely to cause odor and hinder the flow of water through the mesh plate.

[0036] In order to improve the cleaning effect of debris intercepted by the mesh plate, ensure the filtering effect of the mesh plate, avoid clogging of the mesh plate and even the generation of odor, the present invention provides an odor-removing and anti-clogging internal flow grille device, which is used to at least partially overcome the above technical problems and achieve the purpose of effectively removing debris filtered out by the grille mesh plate, avoiding clogging of the grille mesh plate and preventing the generation of odor.

[0037] Example 1:

[0038] like Figures 1 to 5 As shown, this embodiment provides an odor-removing and anti-clogging inner inlet grille device, which includes:

[0039] A flushing assembly, which includes a flat nozzle 21 and a telescopic mechanism 22; the flat nozzle 21 is located on the outside of the mesh plate 11 in the upward section of the inner inlet grille 1 and faces the mesh plate 11, and the length direction of the flat nozzle 21 is parallel to the upward direction of the mesh plate 11; the free end 221 of the telescopic mechanism 22 is fixedly connected to the flat nozzle 21, and can drive the flat nozzle 21 to reciprocate linearly perpendicular to the upward direction of the mesh plate 11.

[0040] The telescopic mechanism 22 can be a linear motor, a cylinder, a hydraulic cylinder, a scissor-type telescopic mechanism 22, a crank 52 slider mechanism, etc., but the present application is not limited thereto.

[0041] As a result, the water flow ejected by the flat nozzle 21 is in the form of a vertical strip, and when it moves back and forth in a horizontal linear motion, a strip-shaped spray path is formed; since each mesh plate 11 continuously rotates along the chain transmission path, under the synthesis of the upward motion of the mesh plate 11 and the horizontal linear motion of the flat nozzle 21, by adjusting the reciprocating frequency of the flat nozzle 21, it is possible to ensure that when a certain mesh plate 11 passes the nozzle height position upward, any point on it can be flushed multiple times, thereby achieving the purpose of strengthening the flushing effect. Specifically, as Figure 3 As shown, for ease of understanding, using the ascending mesh panel 11 as a reference, the flat nozzle 21 moves vertically downward relative to the mesh panel 11 while simultaneously performing horizontal reciprocating linear motion. The figure shows that any point P on the mesh panel 11 is flushed twice by the water jet from the flat nozzle 21. Furthermore, as the flat nozzle 21 reciprocates linearly, the flushing position on the mesh panel 11 changes, causing the mesh panels 11 in the ascending section to slightly deflect and vibrate, which helps to dislodge debris stuck in the holes of the mesh panels 11.

[0042] It should be understood that the chain drive typically rotates the mesh plate 11 at a fixed (and relatively slow) speed. Therefore, the faster the reciprocating linear motion of the flat nozzle 21 perpendicular to the mesh plate 11, the more times any point P on the mesh plate 11 is flushed as it passes the height of the flat nozzle 21. However, this also results in a correspondingly shorter flushing time for point P. Therefore, the reciprocating frequency of the flat nozzle 21 is typically adjusted to ensure that point P is flushed 2-4 times. The rotational speed of the chain drive also is adjusted to ensure that point P is flushed for a sufficient period of time, ensuring effective flushing.

[0043] More preferably, a first guide groove 31 is provided on the inner side of the inner inlet grille 1 , and the flat nozzle 21 is higher than the first guide groove 31 ;

[0044] A baffle 32 is provided above the first guide slot 31 , and a bottom of the baffle 32 is fixedly connected to a side of the first guide slot 31 close to the mesh plate 11 of the downstream section of the inner inlet grille 1 .

[0045] Thus, the first guide groove 31 can be used to receive and guide debris flushed by the flat nozzle 21. The provision of the baffle 32 can prevent debris ejected farther by the water flow from falling into the first guide groove 31, preventing such debris ejected farther from adhering to the mesh panels 11 at corresponding heights in the descending section, thereby ensuring efficient guidance of debris flushed from the mesh panels 11 in the upper and lower sections. It should be understood that the first guide groove 31 has a certain slope along its length, thereby facilitating the discharge of debris that falls into the first guide groove 31.

[0046] Example 2:

[0047] like Figures 1 to 5 As shown, this embodiment is based on embodiment 1, except that, in this embodiment:

[0048] The upper portion of the baffle 32 is inclined toward the mesh plate 11 of the descending section;

[0049] A first cutter 33 is slidably mounted on the side of the baffle 32 facing the upward section mesh plate 11, and the relative sliding direction of the first cutter 33 is parallel to the tilt direction of the baffle 32;

[0050] A first return spring 34 is connected between the first cutter 33 and the baffle 32 . The first return spring 34 causes the upper portion of the first cutter 33 to abut against the inner side of the descending section mesh plate 11 .

[0051] As a result, the filamentous debris 8 (such as hair and fiber) inserted into the holes of the mesh plate 11 is "cut off" (actually a shearing effect caused by the shear force) by the abutment between the first cutter 33 and the inner side of the mesh plate 11 when it passes downward through the upper part of the first cutter 33, thereby causing the filamentous debris 8 inserted into the holes of the mesh plate 11 to separate from the mesh plate 11. Obviously, the section of filamentous debris 8 located on the inner side of the mesh plate 11 in the descending section will slide along the first cutter 33 into the first guide groove 31 and then be guided out (after the water flow from the flat nozzle 21 passes through the ascending section of the mesh plate 11 and reaches the baffle 32 and / or the first cutter 33, it is also beneficial for these sections of filamentous debris 8 and the debris that is sprayed farther and reaches the baffle 32 and / or the first cutter 33 to flow into the guide groove as quickly as possible). Preferably, a blade portion is provided on the upper portion of the first cutter 33 , and the blade portion abuts against the inner side of the mesh plate 11 in the downstream section, thereby strengthening the shearing effect on the filamentous debris 8 with strong toughness.

[0052] Furthermore, a second guide groove 35 is provided on the outer side of the descending section, and a guide plate 36 is provided above the second guide groove 35. The bottom of the guide plate 36 is fixedly connected to the side of the second guide groove 35 close to the mesh plate 11 of the descending section; the upper part of the guide plate 36 is inclined toward the mesh plate 11 of the descending section;

[0053] A second cutter 37 is slidably mounted on the side of the guide plate 36 away from the mesh plate 11 of the downstream section, and the relative sliding direction of the second cutter 37 is parallel to the tilt direction of the guide plate 36;

[0054] A second return spring 38 is connected between the second cutter 37 and the guide plate 36 . The second return spring 38 causes the upper portion of the second cutter 37 to abut against the outer side of the descending section mesh plate 11 .

[0055] Thus, the second guide groove 35 can be used to receive and guide the sections of filamentary debris 8 located outside the mesh plate 11 in the downstream section after being cut by the first cutter 33, preventing these sections of filamentary debris 8 from falling directly into the outflow water below (referring to the water flowing out from both sides after being filtered by the inner inlet grille 1); in addition, for some filamentary debris 8 that has not yet escaped from the mesh plate 11 after being cut by the first cutter 33, the sections located outside the mesh plate 11 in the downstream section can be removed, thereby ensuring the removal effect of the filamentary debris 8. Preferably, a blade portion is provided on the upper portion of the second cutter 37, which abuts the outer side of the mesh plate 11 in the downstream section, thereby strengthening the shearing effect on the more resilient filamentary debris 8. It should be understood that the first cutter 33 can also be lower than the second cutter 37, in which case the second cutter 37 will first cut the filamentary debris 8 on the downstream mesh plate 11.

[0056] It is worth noting that the reciprocating flat nozzle 21 can flush the debris (especially solid particles) stuck in the holes of the mesh plate 11 by repeatedly flushing the mesh plate 11, so that there is no such debris stuck in the holes of the mesh plate 11 on the mesh plate 11 that passes downward through the first cutter 33 and the second cutter 37, thereby preventing the first cutter 33 and the second cutter 37 from being damaged by such debris at the part where they abut against the mesh plate 11 in the downward section (especially when a blade portion is provided, the blade portion is easily damaged, and the first cutter 33 and / or the second cutter 37 cannot normally cut the filamentous debris 8 due to the notch in the blade portion) or push and retract (the first cutter 33 and / or the second cutter 37 no longer abut against the mesh plate 11 during the retraction process, and thus cannot effectively cut the filamentous debris 8 at this time).

[0057] Example 3:

[0058] like Figures 1 to 10 As shown, this embodiment is based on embodiment 1, with the difference that, in this embodiment, the inner flow grille device further includes a filter plate 41, which is fixedly installed in the upstream water channel 7 of the inner flow grille 1, and the upper part of the filter plate 41 is inclined toward the inner flow grille 1.

[0059] It should be understood that the filter plate 41, serving as the primary filtration device upstream of the inner inlet grille 1, has pores larger than those of the mesh plate 11. As a result, the filter plate 41 intercepts larger debris, preventing it from entering the inner side of the inner inlet grille 1. This helps maintain the filtration effectiveness of the inner inlet grille 1 and prevents the pores of the mesh plate 11 of the inner inlet grille 1 from being blocked by large debris, ensuring smooth water flow.

[0060] Furthermore, the inner flow grid device also includes a slag grabbing assembly, which is used to grab the debris intercepted by the filter plate 41.

[0061] Therefore, the debris intercepted by the filter plate 41 is promptly grabbed and removed by the debris grabbing component, thereby ensuring the filtering effect of the filter plate 41 and avoiding the upstream water level rising due to the clogging of the holes in the filter plate 41, resulting in floating large-sized debris overflowing the filter plate 41 and entering the inner side of the inner inlet grille 1.

[0062] Specifically, the slag grab assembly includes a guide rod 51, a crank 52, a connecting rod 53, a rocker 54 and a guide sleeve 55; the rocker 54 includes a first section 541 and a second section 542 whose ends intersect; preferably, the first section 541 and the second section 542 are perpendicular;

[0063] The guide rod 51 is fixedly arranged above the water channel 7 and parallel to the inclination direction of the filter plate 41; the guide sleeve 55 is slidably installed on the guide rod 51, and the guide sleeve 55 is extended along the width direction of the water channel 7 with an axis rod 551, a first stop pin 552 and a second stop pin 553; one end of the crank 52 is hinged to the end of the guide rod 51 away from the water channel 7, and the other end of the crank 52 is hinged to one end of the connecting rod 53; the other end of the connecting rod 53 is hinged to the end of the first section 541 away from the second section 542; the connecting part of the first section 541 and the second section 542 is hinged to the axis rod 551, and the second section 542 is located between the first stop pin 552 and the second stop pin 553; a slag bucket 56 is fixedly connected to the end of the second section 542 away from the first section 541.

[0064] The upper portion of the filter plate 41 is higher than the water level of the water channel 7 , and a third guide groove 57 is fixedly connected to one side of the upper portion of the filter plate 41 close to the inner inlet grille 1 .

[0065] Thus, by rotating the crank 52, the slag grabbing bucket 56 can grab large-sized debris intercepted by the filter plate 41 at a certain frequency, thereby achieving debris grabbing. Specifically, the operation process of the slag grabbing assembly is as follows:

[0066] Please refer to Figure 10 , Figure 10 The schematic diagram of the movement of the slag grab assembly is shown in FIG. 1 , wherein the dotted line represents the movement trajectory of the hook tip of the slag grab bucket 56 during the counterclockwise rotation of the crank 52. Figures 6 to 9 The figure shows a cross-sectional view of the inner inlet grid device when the tip of the slag grab 56 is located at each "turning point" on the motion trajectory during the rotation of the crank 52 (only the part where the slag grab assembly is installed is shown). Figure 6 As shown, Figure 6In the embodiment, the slag grab 56 is located at the upper right corner of the motion trajectory. At this time, the crank 52 is rotated counterclockwise, which will cause the rocker 54 to rotate clockwise around the shaft 551 (because the rotational friction between the rocker 54 and the shaft 551 is less than the sliding friction between the guide sleeve 55 and the guide rod 51. Based on the law of least resistance, in the slag grab assembly, the rocker 54 swings first, and then the guide sleeve 55 slides along the guide rod 51) until the second section 542 is blocked by the first stop pin 552, and then the slag grab 56 swings to the position shown in FIG. Figure 7 After that, the crank 52 is rotated counterclockwise. Since the second section 542 is blocked by the first stop pin 552, the rocker 54 cannot continue to rotate, and the guide sleeve 55 slides downward along the guide rod 51, driving the grab bucket 56 to be inserted underwater along a trajectory parallel to the guide rod 51 (inserted underwater until Figure 8 ), obviously, in this process, the swinging action of the rocker 54 before the insertion action makes the insertion path avoid the area near the upstream of the filter plate 41 (referring to the floating debris collection area near the filter plate 41 upstream of the filter plate 41); thereafter, the crank 52 continues to rotate counterclockwise. Based on the law of least resistance, the rocker 54 will first rotate counterclockwise around the shaft 551 until the second section 542 is blocked by the second stop pin 553. At this time, the slag bucket 56 is in the Figure 9 The position shown in the figure is shown in the figure. During this process, the hook tip of the grab bucket 56 is inserted into the lower part of the filter plate 41 and grabs some debris deposited on the lower part of the filter plate 41; thereafter, the crank 52 is rotated counterclockwise. Since the second section 542 is blocked by the second stop pin 553, the rocker arm 54 cannot continue to rotate, and then the guide sleeve 55 will slide upward along the guide rod 51, driving the hook tip of the grab bucket 56 to slide along the filter plate 41 toward the upstream side to the top position of the filter plate 41 (because the guide rod 51 and the filter plate 41 are parallel, the upward trajectory of the grab bucket 56 is parallel to the filter plate 41, and the position where the grab bucket 56 ends its upward movement is shown in the figure). Figure 6 As shown), during this process, the grab bucket 56 can grab the debris (including sediment debris, suspended debris and floating debris) near the filter plate 41 and lift it to the water surface, and then based on the inclined design of the grab bucket 56 (refer to Figure 1 、 Figure 6 It can be seen that the grab bucket 56 is roughly L-shaped, and its side is a fence-shaped water filter, thereby reducing the resistance of the grab bucket 56 during the upward movement. The bottom plate is a smooth inclined surface, thereby facilitating the discharge of the grabbed debris). The grabbed debris quickly slides into the third guide groove 57.

[0067] It should be understood that in order to ensure that the slag grabbing assembly operates according to the law of least resistance, the hinge between the rocker arm 54 and the shaft rod 551 is kept well lubricated, and means are taken to increase friction between the guide sleeve 55 and the guide rod 51 (such as increasing the friction coefficient) or to apply a load to the guide sleeve 55 to increase the running resistance difference (referring to increasing the running resistance difference between the rotation of the rocker arm 54 relative to the shaft rod 551 and the sliding of the guide sleeve 55 relative to the guide rod 51).

[0068] Example 4:

[0069] This embodiment is based on embodiment 3, with the difference that, in this embodiment, the inner air intake grille device further includes a suction component, which is used to suck the air inside the inner air intake grille 1.

[0070] In the event of an odor generated inside the inner intake grille 1 (especially during high temperatures in summer when the water contains organic debris, which can easily produce odors, and if filamentous debris 8 remains in the holes of the mesh plate 11, these filamentous debris 8 are more likely to adhere to organic debris and thus cause odor), the suction component sucks the air inside the inner intake grille 1, thereby directing the odorous gases for separate subsequent treatment. This can effectively remove the odor generated by the inner intake grille device, optimize the air environment at the location of the inner intake grille 1, and facilitate routine maintenance of the inner intake grille device by staff. It should be understood that the subsequent treatment of the odorous gases can be handled using existing odorous gas treatment systems, and this application will not elaborate on this.

[0071] Specifically, the suction assembly includes a cylinder body 61, which is fixedly mounted on one side of the water channel 7 and parallel to the guide rod 51. An air inlet pipe 62 and an air outlet pipe 63 are connected to one end of the cylinder body 61, and the other end is connected to the air.

[0072] A push rod 554 extending from the guide sleeve 55 is parallel to the guide rod 51 , and a piston is fixedly mounted on one end of the push rod 554 away from the guide sleeve 55 , and the piston is slidably mounted inside the cylinder body 61 ;

[0073] The air intake pipe 62 is connected to the inner side of the inner air intake grille 1 .

[0074] Thus, as the crank 52 rotates to drive the slag grab 56 to grab slag, the reciprocating linear motion of the guide sleeve 55 along the guide rod 51 can drive the piston to reciprocate linearly in the cylinder body 61, thereby allowing the intake pipe 62 to draw air from the inner side of the inner intake grille 1 and output the sucked odorous gas through the outlet pipe 63 to the odorous gas treatment system for subsequent treatment. In addition, the process of the guide sleeve 55 driving the piston to reciprocate linearly in the cylinder body 61 increases the resistance to the sliding movement of the guide sleeve 55 relative to the guide rod 51, which helps the slag grab 56 of the slag grab assembly to operate according to the preset movement and trajectory. It should be understood that a one-way valve is installed in both the intake pipe 62 and the outlet pipe 63, so that gas can only enter the cylinder body 61 through the intake pipe 62 and be discharged through the outlet pipe 63.

[0075] In this application, the term "hinge" means that the two can only rotate relative to each other, such as the rotation setting of the hole and the shaft rod, which can achieve the limitation of axial relative movement by setting a shoulder on the shaft and a limit groove in the hole; the term "sliding installation" means that the two can only slide relative to each other, such as dovetail grooves, T-slots and other structures.

[0076] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail.
