Description

[Technical field]

[0001] The present application relates to the field of wastewater treatment technology, in particular to a water resource ecological management grill machine. [Background technology]

[0002] The grill machine is a dedicated water treatment equipment that can continuously and automatically block and remove various types of impurities in the fluid. It is mainly composed of devices such as a winding mechanism, a wire rope, a rake, a wire rope pulley, a floor fixed rail, and a movable driving positioning. The rake teeth connected to the rake are connected to the gaps of the grill and driven by the driving mechanism to drive the grill to move the rake in the opposite direction to the flow direction of the water flow. When the rake tooth chain runs to the top of the device, each set of rake teeth will perform a relative self-cleaning motion between the cleaning roller at the top end and the guide of the groove wheel and the curved rail, causing the solids to fall by gravity, and the remaining solids will be cleaned by the reverse movement of the cleaner to clean the miscellaneous matter attached to the rake teeth and the grill.

[0003] In the process of cleaning the water body, water constantly flows through the gaps in the grill, and the impurities that are not captured by the rake in the water flow are blocked by the grill. When the grill is moved to the top to clean, the rake teeth are connected between the gaps in the grill. In addition, the cleaning methods of the grill and the rake are different, so the cleaning efficiency of the grill is poor. When the grill moves downward again, impurities will adhere to the surface of the grill, and the impurities will continue to move into the cleaned water body following the grill, so that the impurities will pollute the cleaned water body. In addition, it is necessary to install a multi-stage grill machine in the water tank to perform impurity removal treatment, which increases the cost of impurity removal. When impurities adhere to the gaps in the grill, the flow efficiency of the water flow will be hindered and the treatment speed of the water body will be reduced. Summary of the Invention [Problem to be solved by the invention]

[0004] The present application proposes a water resource ecological management grill machine that has the advantages of reducing the difficulty of grill cleaning and reducing impurities contained in the water after cleaning the tank, and solves the problems of the low efficiency of grill cleaning proposed in the above background art and the efficiency of ensuring that the water body always flows. [Means for solving the problem]

[0005] In order to achieve the above object, the present application adopts the following technical proposal, which is a water resource ecological management grill machine, including a water tank, a casing installed inside the water tank, an impurity collecting groove for collecting impurities provided at the lower side of the casing, a grill driven by a motor to rotate is connected to the inside of the casing at equal intervals in the horizontal direction, rake teeth for collecting impurities in the water are connected between the grills at equal intervals in the circumferential and horizontal directions, a fixing groove is opened on the inside surface of the casing, a support rod is connected to the inside of the fixing groove for sliding in the vertical direction, a fixing frame is fixedly connected to the bottom end of the support rod located outside the grill, a fixed rod is connected to the inside of the fixing frame at equal intervals in the horizontal direction, a spool that slides vertically inside the fixing groove is fixedly connected to the bottom end of the support rod located inside the grill, a rotating plate in the opposite direction to the rotating direction of the grill is provided below the spool, and a fixed plate that moves following the rotating plate is fixedly connected to the outer side of the rotating plate at equal intervals.

[0006] Furthermore, the cross-sectional shape of the fixing groove is a shape formed by combining two rectangles horizontally, the horizontal planes of the top ends of the two rectangles are the same, and the bottom end face of one rectangle away from the fixing frame is lower than the bottom end face of the other rectangle.

[0007] Furthermore, the shape of the support rod is an inverted "U" shape, and the horizontal portion of the support rod is located inside one rectangle close to the fixing frame inside the fixing groove, and the vertical portion of the support rod away from the fixing frame is located inside another rectangle away from the fixing frame of the fixing groove.

[0008] Furthermore, the fixed frame is installed at an angle like the entire casing, and its side faces the rake teeth, the initial state of the fixed frame is located below the liquid level, the top and bottom ends of the fixed frame are respectively located between the two rake teeth, and the side of the fixed frame is located in the direction of opening to the outside of the rake teeth, the entire fixed frame does not affect the movement of the rake teeth, and the upward movement process of the fixed frame is synchronized with the upward movement of a set of rake teeth on the side.

[0009] Furthermore, the fixed rods are laterally distributed inside the fixed frame, and the installation positions of the fixed rods inside the fixed frame correspond to the gap positions between two adjacent grilles.

[0010] Furthermore, the spool has a cylindrical shape, and when the fixed frame is located below the liquid surface, the spool is located at the bottom end inside the fixed groove.

[0011] Furthermore, the cross-sectional shape of the rotating plate is a combination shape with an inverted right triangle on top and a rectangle on the bottom, and the chamfered rectangle of the hypotenuse of the right triangle is away from the side edge of the fixed frame, the side of the rectangle away from the fixed frame is in the same plane as the right-angled side of the right triangle away from the fixed frame, and the apex of the rectangle is another right-angled side, the rectangular portion of the rotating plate is parallel to the vertical portion of the grill, and the rectangular portion of the rotating plate is closer to the side of the grill away from the fixed frame, and the entire rotating plate is divided into segment A, segment B and segment C.

[0012] Furthermore, the fixed plate is installed obliquely outside the rotating plate, and the top end of the fixed plate located in the vertical portion of the rotating plate is away from the fixed frame, and the bottom end of the fixed plate is close to the fixed frame. Effect of the Invention

[0013] The beneficial effects of the present invention are as follows: by installing a fixed plate on the outside of the rotating plate, the fixed plate follows the movement of the rotating plate, and the fixed plate causes the water inside the grill to flow back outward; by installing the fixed plate at an angle, the water flowing outside the grill is directed diagonally downward, and the water flow flowing in the opposite direction through the gaps in the grill is directed diagonally toward the inside of the rake teeth, preventing the impurities collected by the grill from following the water flow and flowing inside the rake teeth to be collected again, reducing the accumulation and adhesion of impurities between the grills, and making the grill easier to clean.

[0014] By installing the fixed frame between the two vertical rake teeth, part of the reverse water flowing out from inside the grill flows out between the vertically adjacent rake teeth. At this time, when the fixed frame is between the two vertical rake teeth, the water flow flows to the sides of the fixed frame and fixed rod, and the reverse water flow containing a large amount of impurities that flows out through the gaps in the grill is received by the sides of the fixed frame and fixed rod. The fixed frame and fixed rod further filter out the impurities in the water flow, reduce the escape of impurities between the grills, and ensure the collection efficiency of impurities.

[0015] By installing the fixed plate at an angle, when the rotating plate approaches the outside of the fixed frame and moves in the downward vertical direction, i.e., to the b segment on the outside of the rotating plate, the fixed plate moves the water flow diagonally downward of the fixed plate in the direction away from the fixed frame, and further accelerates the forward flow of the water flow, ensuring the efficiency of the water flow. The fixed plate presses the water flow diagonally downward, and at the same time generates turbulence in the water flow diagonally upward of itself. After the turbulence acts on the inner wall of the grill, the rotating plate approaches the fixed plate connected to the fixed frame and moves relatively away from the inside of the grill, so that when the fixed plate adjacent to the fixed frame presses the water flow, the circumference of the grill The impact of the direction on the water body is relatively small, preventing the escape of impurities; and when a small amount of impurities adheres to the side gaps close to the fixed frame of the grill, the gaps between the grills will vibrate slightly due to turbulence, and the impurities will be instantly released from the gaps in the grill, after which the water body will flow back inside the grill, ensuring effective water flow, and the water flow will push the impurities back to the outside of the grill again. That is, the impact of turbulence on the water body around the grills is small, thereby achieving effective flow of the water body between the grills and at the same time ensuring the stability of the impurities blocked outside the grill.

[0018] Hereinafter, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application, and obviously, the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative efforts are within the scope of protection of the present application.

[0019] Example 1 1 and 2, the water resource ecological management grill machine includes a water tank 1, a casing 2 is installed inside the water tank 1, an impurity collecting groove 3 is provided under the side of the casing 2 to collect impurities, a grill 4 driven by a motor to rotate is connected to the inside of the casing 2 at equal distances in the horizontal direction, a cleaning roller is connected above the grill 4 inside the casing 2, and a gap is provided between the cleaning roller and the rake teeth 5 for rotating and cleaning, and a brush roller is connected to the inside of the casing 2, separated from the top of the grill 4 and located above the impurity collecting groove 3, and the brush roller cleans the surface of the grill 4, and a motor is installed above the casing 2 and drives the rotating shaft connected to the inside of the grill 4 by a rotating shaft and a belt to rotate, the rotating roller rotates the connected grill 4, and between the grill 4, a rake is connected to collect impurities in the water. The brake teeth 5 are connected at equal distances in the circumferential and horizontal directions, and a fixed groove 6 is opened on the inner surface of the casing 2. Referring to FIG. 3, a support rod 7 is connected to slide vertically inside the fixed groove 6, and a fixed frame 8 is fixedly connected to the bottom end of the support rod 7 located on the outside of the grill 4, so that the water flow inside the water tank 1 always flows gently in the direction away from the fixed frame 8, and a fixed rod 9 is connected to the inside of the fixed frame 8 at equal distances in the horizontal direction. Referring to FIG. 4, the broken line indicates the liquid level position, and a spool 10 that slides vertically inside the fixed groove 6 is fixedly connected to the bottom end of the support rod 7 located on the inside of the grill 4. A rotating plate 11 is provided below the spool 10 and rotates in the opposite direction to the grill 4. The rotating plate 11 is driven by the rotation of a motor, and a fixed plate 12 that moves following the rotating plate 11 is fixedly connected to the outer circumferential side of the rotating plate 11 at an equal distance.

[0020] Example 2 Example 2 is based on Example 1. Referring to FIG. 4, the cross-sectional shape of the fixed groove 6 is a shape of two rectangles combined horizontally, the horizontal plane of the top ends of the two rectangles is the same, and the bottom end face of one rectangle away from the fixed frame 8 is lower than the bottom end face of the other rectangle, and the sides of the two rectangles are both parallel to the vertical parts of the grill 4. The support rod 7 slides inside the fixed groove 6 in a direction parallel to the grill 4, and the opening of the fixed groove 6 toward the outside of the grill 4 is located above the liquid level, which prevents the uncleaned water flow from passing through the fixed groove 6 into the inside of the grill 4 and contaminating the cleaned water flow, and ensures the effectiveness of cleaning the grill 4 and the rake teeth 5.

[0021] 2 and 4, the shape of the support rod 7 is an inverted "U" shape, and the horizontal part of the support rod 7 is located inside one rectangle close to the fixed frame 8 inside the fixed groove 6, and the vertical part of the support rod 7 away from the fixed frame 8 is located inside another rectangle away from the fixed frame 8 of the fixed groove 6. The upward movement process of the support rod 7 is synchronized with the upward movement of the rake teeth 5. With the installation of the support rod 7, when the spool 10 connected to one end of the support rod 7 is pressed by the fixed plate 12, the support rod 7 moves the connected spool 10 and the fixed frame 8 upward, and when one of the fixed plates 12 passes the outside of the spool 10, the spool 10 is fixed to the lower part of the spool 10. Without the pressure of the fixed plate 12, the support rod 7, fixed frame 8 and spool 10 fall to the lowest position again under their own weight, and then wait for the next pressure from the fixed plate 12. When the fixed plate 12 presses, the support rod 7 again moves the fixed frame 8 and spool 10 upward, and the fixed frame 8 then vibrates and presses to move the impurities on the liquid surface to the inside of the water body, so that the impurities floating on the liquid surface are completely permeated into the water body inside the water tank 1, preventing the impurities from drying out, and the permeated impurities are more easily trapped and collected by the rake teeth 5 and grill 4. As a result, the impurities accumulated on the liquid surface of the water tank are reduced, and the difficulty of collecting the impurities floating on the liquid surface is reduced.

[0022] 1 and 4, the fixed frame 8 is installed at an angle like the whole casing 2, and its side faces the rake teeth 5. The initial state of the fixed frame 8 is below the liquid level, and the top and bottom ends of the fixed frame 8 are respectively located between the two rake teeth 5, and the side of the fixed frame 8 is located in the direction of opening to the outside of the rake teeth 5. The whole fixed frame 8 does not affect the movement of the rake teeth 5, and the upward movement process of the fixed frame 8 is synchronized with the upward movement of the rake teeth 5. Due to the installation of the fixed frame 8, part of the water flowing out of the grill 4 in the reverse direction is directed to the inside of the rake teeth 5. When pressed, another part flows out between the adjacent rake teeth 5, and the fixed frame 8 is positioned between the two rake teeth 5, allowing the water flowing out between the rake teeth 5 to flow to the side of the fixed frame 8, and the water flow containing many impurities flowing in the opposite direction from this part is blocked by the sides of the fixed frame 8 and the fixed rod 9, so that the impurities in the water body are blocked and collected by the fixed frame 8 and the fixed rod 9. In the process of the fixed frame 8 returning to the water body, the fixed frame 8 and the fixed rod 9 release the impurities blocked in this part back to the inside of the rake teeth 5 in the direction in which the whole flows along the water body, ensuring effective collection of impurities.

[0023] 2 and 3, the fixed rods 9 are distributed horizontally inside the fixed frame 8, and the installation positions of the fixed rods 9 inside the fixed frame 8 correspond to the gap positions between two adjacent grilles 4. The fixed rods 9 and the fixed frame 8 are installed at the same diagonal, so that the fixed rods 9 can block the reverse water flow that flows out between the grilles 4. When the fixed rods 9 follow the fixed frame 8 and move vertically below the liquid level again, they are simultaneously subjected to the vertical impact of the water flow, and the impurities are more likely to move away from the fixed frame 8 and the fixed rods 9 and flow in the direction of the rake teeth 5, thereby ensuring the efficiency of impurity collection.

[0024] Referring to FIG. 4, the spool 10 is cylindrical in shape. When the fixed frame 8 is located below the liquid level, the spool 10 is located at the bottom end of the inside of the fixed groove 6. The shape and installation of the spool 10 is such that the rotating plate 11 is easy to press the spool 10 by the fixed plate 12 to move it vertically, and the spool 10 is easy to slide vertically within the fixed groove 6. During the movement of the spool 10, the fixed frame 8 is moved by the support rod 7. Since there is a gap between the rotating plate 11 and the fixed plate 12 connected to the outside of the rotating plate 11, the movement of the fixed plate 12 pressing the spool 10 is intermittent, and the fixed plate 12 presses the water flow inside the grill 4 to conform to the shape of the water tank 1, and the action on the grill 4 in the part close to the liquid level position is also intermittent. 4 and 5, the cross-sectional shape of the rotating plate 11 is a combination shape with an inverted right-angled triangle on the top and a rectangle on the bottom, and the chamfered rectangle of the hypotenuse of the right-angled triangle is away from the side of the fixed frame 8, the side of the rectangle away from the fixed frame 8 is in the same plane as the right-angled side of the right-angled triangle away from the fixed frame 8, and the apex of the rectangle is another right-angled side, the rectangular part of the rotating plate 11 is parallel to the vertical part of the grill 4, and the rectangular part of the rotating plate 11 is closer to the side of the grill 4 away from the fixed frame 8, the entire rotating plate 11 is divided into segment a, segment b and segment c, and according to the shape and configuration of the rotating plate 11, segment a is the section where the rotating plate 11 causes the fixed plate 12 to press the water flow vertically downward to flow diagonally in the direction of the fixed frame 8 and the rake teeth 5, causing the water flow to flow back between the grill 4, segment b is the section where the rotating plate 11 causes the fixed plate 12 to move vertically downward, and the fixed plate 12 moves diagonally downward The water flow is pressed vertically downward and flows in a direction away from the fixed frame 8, and the water flow above the fixed plate 12 becomes turbulent due to the pressure of the fixed plate 12. The c segment is a section in which the rotating plate 11 moves the fixed plate 12 vertically upward. Since the side of the c segment is closer to the inner wall of the grill 4, the water flow disturbed by the pressure of the fixed plate 12 acts directly on the inside of the grill 4, and the diagonal water flow pressed by the fixed plate 12 flows diagonally directly to the inside of the rake teeth 5. The impurities remaining on the surface of the grill 4 after cleaning at the top end inside the casing 2 between the grills 4 flow diagonally along the water flow directly to the inside of the rake teeth 5. The rake teeth 5 directly collect the remaining impurities in this part and pull them to the side of the grill 4 close to the fixed frame 8, and then follow the movement of the grill 4 to be cleaned at the top end. This reduces the contamination of the water after cleaning caused by the remaining impurities on the surface of the grill 4, and reduces the cost of cleaning the water body inside the water tank 1.

[0025] 4, the fixed plate 12 is installed obliquely on the outside of the rotating plate 11, and the top end of the fixed plate 12 located in the vertical portion of the rotating plate 11 is away from the fixed frame 8, and the bottom end of the fixed plate 12 is close to the fixed frame 8. Since the fixed plate 12 is installed obliquely, when the rotating plate 11 moves vertically downward close to the outside of the fixed frame 8, the fixed plate 12 presses the water flow obliquely downward of the fixed plate 12 to move in the direction away from the fixed frame 8, and further accelerates the forward flow of the water flow, thereby ensuring the flow efficiency of the water flow. While the fixed plate 12 presses the water flow obliquely downward, turbulence is generated in the water flow obliquely upward of itself. After the turbulence acts on the inner wall of the grill 4, the rotating plate 11 moves close to the fixed plate 12 connected to the fixed frame 8 and relatively away from the inside of the grill 4, so that the side close to the fixed frame 8 When the fixed plate 12 presses the water flow, the impact on the water body in the circumferential direction of the grill 4 is relatively small, which prevents impurities from escaping; furthermore, when a small amount of impurities adhere to the gaps on the side close to the fixed frame 8 of the grill 4, the gaps between the grills 4 will be slightly shaken by the turbulent flow, causing the impurities to be instantly released from the gaps in the grill 4, and then the water body will flow back to the inside of the grill 4, ensuring the effective flow of the water flow, and the water flow will again press the impurities back to the outside of the grill 4; that is, since the impact of the turbulent flow on the water body around the grill 4 is small, an effective flow of the water body between the grills 4 is achieved, and at the same time, the impurities blocked outside the grill 4 are stabilized, and the flowing water in the gaps outside the grill 4 is not affected, which further improves the collection of impurities.

[0026] The method of use (operation principle) of the present invention is as follows: When removing impurities from the water flow in the water tub 1, the grill 4 is installed inside the water tub 1, and the grill 4 rotates clockwise by the motor installed at the top through the rotation shaft and belt transmission, and the rotating plate 11 inside the grill 4 is driven by the transmission shaft to rotate counterclockwise. When the water flow inside the water tub 1 flows slowly toward the grill 4, the grill 4 rotates and the rake teeth 5 facing the flow direction of the water flow move from bottom to top, and the impurities in the water flow in the water tub 1 are caught by the inside of the top end of a set of horizontal rake teeth 5, and the irregularities in the water flow in the water tub 1 are removed between the grill 4. When the grill 4 moves a set of rake teeth 5 close to the liquid surface, the side of the rotating plate 11 close to the fixed frame 8 simultaneously moves the fixed plate 12 downward, and the rotating plate 11 simultaneously moves a set of fixed plates 12 close to the liquid surface. As the rotating plate 11 continues to move downward, the fixed plate 12 moves downward and at the same time diagonally from the direction close to the fixed frame 8 to the direction away from the fixed frame 8 due to the inverted right-angled triangular shape installed near the upper part of the rotating plate 11. Furthermore, the fixed plate 12 presses the water flow inside the grill 4 to move it to the outside of the grill 4, and the grill near the liquid surface moves downward. Just before the grill 4 leaves the water body, it is struck in the opposite direction by the water flow pressed by the fixed plate 12, and impurities blocked by the gaps in the grill 4 leave between the grill 4, and the top end of the rotating plate 11, the side away from the fixed frame 8, abuts one of the fixed plates 12 against the underside of the spool 10, and presses the spool 10 upward during the movement, which moves the spool 10 upward, causing the fixed frame 8 to move upward by the support rod 7, and further moving the rake teeth 5 adjacent to the fixed frame 8 upward in sync, and when the water flow is pressed by the fixed plate 12 and flows in the opposite direction to the water body, the grill 4 Part of the water flowing out from between the grills 4 impacts the inside of the rake teeth 5, and part of the water flowing out from between the grills 4 flows out between the adjacent vertical rake teeth 5. The water flowing out from between the vertical rake teeth 5 is obstructed by the sides of the fixed frame 8 and the fixed rod 9, and is also obstructed by the slopes of the fixed frame 8 and the fixed rod 9, causing the water flow to flow back inside the rake teeth 5. The water flow containing a large amount of impurities that has flowed out from the middle of the grills 4 is blocked between the fixed frame 8 and the fixed rod 9, and at the same time, the impurities are filtered, and the water flow containing a large amount of impurities that has flowed out from between the grills 4 is caused to flow back inside the rake teeth 5.The rake teeth 5 again filter this part of the water flow to collect impurities, and when the grill 4 leaves the liquid surface, the amount of impurities attached to the surface of the grill 4 is reduced, and the difficulty of cleaning the grill 4 is further reduced. When the grill 4 is driven to move the rake teeth 5 to the top end, the rake teeth 5 cross and clean with a gap between them and the cleaning roller at the top end, and the grill 4 is brushed and cleaned by the brush roller located at the top end of the casing 2 and leaving the grill 4, and the cleaned impurities fall into the inside of the impurity collecting groove 3 and are collected.
