Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a water-powered grille dirt removal device. Background Art

[0002] The screen cleaner is a solid-liquid separation device that can continuously remove impurities from fluids. It is an indispensable special equipment in the production processes of urban sewage treatment, water plants, power plant water inlets, textiles, food processing, papermaking, leather and other industries. It is currently the most commonly used decontamination equipment in China.

[0003] The existing screen sewage remover is mainly composed of a driving device, a frame, a screen, a slag support plate, a tooth rake and a conveyor. When in use, under the action of the hydrodynamic flow, larger floating objects and suspended matter in the sewage are intercepted by the screen. At the same time, the tooth rake cooperates with the slag support plate to transport the garbage intercepted by the screen, so that the garbage falls into the conveyor through the waste discharge port on the top of the frame. After being transported to the placement position, it will be carried out on the transfer vehicle for the next step of processing.

[0004] However, when the above-mentioned screen cleaner is actually used, in the process of dropping materials, in order to ensure that the garbage can fall smoothly into the conveyor, a guide plate will be provided. Because the garbage is fished out of the sewage, a certain amount of water will remain on the garbage, which causes the garbage to easily adhere to the guide plate due to the water content in the plastic bags and other garbage when falling into the conveyor. Especially when there is a lot of adhesion, it will also affect the speed of dropping materials. At this time, the operator needs to solve it manually, so it is urgently needed to improve the existing screen cleaner. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1

[0033] A water powered grille decontamination device, such as Figure 1 - Figure 4 As shown, it includes a body 1, a tooth rake 2 and a conveyor 3. A guide plate 1 4 and a guide plate 2 5 for guiding garbage are rotatably installed at the discharge port position at the bottom of the body 1, so that the garbage falling from the tooth rake 2 will be guided by the guide plate 1 4 and the guide plate 2 5, thereby ensuring that the garbage will smoothly enter the conveyor 3. Two mutually meshing gears 6 are rotatably installed on the outer wall on one side of the bottom of the body 1, and one gear 6 is connected to the guide plate 1 4, and the other gear 6 is connected to the guide plate 2 5, so that when the guide plate 1 4 changes its angle, the gear 6 will start to rotate. Under the action of the two gears 6, the guide plate 2 5 will rotate synchronously. At the same time, two mutually meshing gears 6 are also rotatably installed on the outer wall on the other side of the bottom of the body 1, further ensuring that the guide plate 1 4 and the guide plate 2 5 will rotate synchronously.

[0034] Furthermore, springs 8 are installed on the outer walls of the guide plate 1 4 and the guide plate 2 5, and a mounting frame 9 connected to the spring 8 is installed at the bottom of the body 1, so that when the guide plate 1 4 and the guide plate 2 5 start to rotate, the corresponding spring 8 will be squeezed by the corresponding mounting frame 9 and the guide plate 1 4 and the guide plate 2 5. When the guide plate 1 4 and the guide plate 2 5 lose their restrictions and no longer rotate, the spring 8 at this time will use its own elastic force to push the guide plate 1 4 and the guide plate 2 5 to the original position. At the same time, because the outer walls of the guide plate 1 4 and the guide plate 2 5 are in contact with the outer wall of the bottom end of the body 1, the guide plate 1 4 and the guide plate 2 5 will collide with the outer wall of the bottom end of the body 1 when they are reset, so that the guide plate 1 4 and the guide plate 2 5 start to vibrate, and the garbage attached to the guide plate 1 4 and the guide plate 2 5 will fall off, thereby reducing the occurrence of accidents in which a large amount of garbage is attached to the guide plate 1 4 and the guide plate 2 5;

[0035] Furthermore, in the present embodiment, the horizontal plane at the top of the guide plate 4 is set to be higher than the horizontal plane at the bottom of the tooth rake 2 which starts to run into the sewage, so that the tooth rake 2 will contact the top side wall of the guide plate 4 during the process of running into the sewage. As the tooth rake 2 continues to move, the angle of the guide plate 4 begins to change, so that the guide plate 4 obtains the power to rotate, so that the vibration of the guide plate 1 4 and the guide plate 2 5 can be achieved without adding additional electrical appliances, which is more convenient to use.

[0036] See also Figure 2 - Figure 4 Because the guide plate 1 4 and the guide plate 2 5 have different inclination angles, the tops of the guide plate 1 4 and the guide plate 2 5 are not located in the same horizontal plane. At the same time, the horizontal plane at the top of the guide plate 1 4 is set to be higher than the horizontal plane at the top of the guide plate 2 5, so that the tooth rake 2 will not contact the guide plate 2 5 during operation, and then after the guide plate 1 4 and the guide plate 2 5 are installed, the tooth rake 2 can still run smoothly.

[0037] See also Figure 2 - Figure 4 A plurality of guide rods 7 are installed at equal intervals on the outer walls of the guide plates 1 4 and 2 5. When the guide plates 1 4 and 2 5 rotate, the corresponding guide rods 7 will be driven to rotate. Since the guide rods 7 are slidably connected with the mounting frame 9, the rotation of the guide plates 1 4 and 2 5 will be restricted and supported by the guide rods 7, thereby ensuring the stability of the guide plates 1 4 and 2 5 during rotation. Moreover, since a spring 8 connected with the mounting frame 9 is sleeved on the outer walls of the plurality of guide rods 7, the plurality of springs 8 will cooperate with each other to ensure that the guide plates 1 4 and 2 5 can be smoothly reset.

[0038] See also Figure 2 - Figure 4 Because the top of the guide plate 5 is where the most garbage falls, a vibration mechanism is provided at the end of the guide plate 5. The vibration mechanism is composed of a vibration plate 10, a mounting groove 11, a limit rod 12 and a load-bearing frame 13;

[0039] Specifically, the vibration plate 10 in the vibration mechanism is installed at the end of the guide plate 25, and the end of the vibration plate 10 protrudes from the guide plate 25, so that the vibration plate 10 will vibrate when it is knocked and squeezed. The setting of the vibration plate 10 can increase the vibration effect of the guide plate 25, and further reduce the probability of garbage adhering to the guide plate 25 in large quantities. At the same time, a mounting groove 11 for mounting the vibration plate 10 is also opened at the end of the guide plate 25, and the width and length of the opening of the mounting groove 11 are greater than the width and length of the end of the guide plate 25, so that there is enough space in the guide plate 25 for the vibration plate 10 to swing, thereby ensuring that the vibration plate 10 can increase the vibration effect of the guide plate 25, and two load-bearing The limit rod 12 is fixedly installed between the two load-bearing frames 13, and the distance between the limit rod 12 and the central axis of the guide plate 25 when rotating is smaller than the distance between the end of the vibration plate 10 and the central axis of the guide plate 25 when rotating. When the guide plate 25 rotates, the end of the vibration plate 10 will contact the outer wall of the limit rod 12. At this time, the guide plate 25 is still rotating, causing the vibration plate 10 to begin to bend until it passes through the limit rod 12. When the vibration plate 10 is separated from the limit rod 12, the vibration plate 10 will begin to restore its shape under the action of its own material, causing the vibration plate 10 to obtain the power to swing, so that the vibration plate 10 will start to swing with the rotation of the guide plate 25, thereby increasing the vibration effect of the guide plate 25.

[0040] See also Figure 3 and Figure 4 A plurality of vibration plates 10 are installed at equal intervals at the end of the guide plate 25. The synchronous swinging of the plurality of vibration plates 10 will further increase the vibration effect of the guide plate 25. At the same time, because the sum of the intervals between the plurality of vibration plates 10 is less than the length of the limiting rod 12, the guide plate 25 will make the plurality of vibration plates 10 synchronously contact with the limiting rod 12 when rotating, ensuring that all the vibration plates 10 will start to swing as the guide plate 25 rotates. Embodiment 2

[0041] A water powered grille decontamination device, such as Figure 1 - Figure 5As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the technically identical parts will not be repeated here. The difference is that in this embodiment, a limit block 14 corresponding to the vibration plate 10 is symmetrically installed at the inner end of the mounting groove 11, so that after the limit block 14 is installed in the mounting groove 11, it will be in contact with the limit block 14, so that the position of the vibration plate 10 in the limit block 14 is limited, and at the same time, a bolt that penetrates the outer wall of the limit block 14 and the outer wall of the end of the vibration plate 10 is threadedly installed on the outer wall of the guide plate 2 5, so that after the vibration plate 10 is installed in the mounting groove 11, the position of the end of the vibration plate 10 in the mounting groove 11 can be fixed by tightening the bolt, and at the same time, it is convenient for the subsequent replacement of the vibration plate 10, and the outer end corners of the limit block 14 and the inner end corners of the vibration plate 10 are both beveled designs, which effectively reduces the difficulty of installing the vibration plate 10.

[0042] The working principle of the utility model is as follows: when using the device, first start the body 1 to make the tooth rake 2 start to run. With the operation of the tooth rake 2, the garbage intercepted by the grille will be driven upward by the tooth rake 2. With the steady operation of the tooth rake 2, the garbage gradually falls to the discharge port. At this time, the guide plate 1 4 and the guide plate 2 5 will guide the fallen garbage so that the garbage enters the conveyor 3. Then the tooth rake 2 will contact the outer wall of the guide plate 1 4. With the continuous movement of the tooth rake 2, the angle of the guide plate 1 4 will begin to change, which will drive the guide plate 2 5 to rotate synchronously through the gear 6, so that the spring 8 is squeezed by the guide plate 1 4 and the guide plate 2 5. With the separation of the tooth rake 2 from the guide plate 1 4, the spring 8 will push the guide plate 1 4 and the guide plate 2 5 to the original position, causing the guide plate 1 4 and the guide plate 2 5 to collide with the body 1. At this time, the guide plate 1 4 and the guide plate 2 5 will begin to vibrate, and the guide plate 1 4 and the guide plate 2 5 attached to the guide plate 1 4 and the guide plate 2 5 will be moved. The garbage on the guide plate 1 4 and the guide plate 2 5 is shaken off, thereby reducing the accident of a large amount of garbage adhering to the guide plate 1 4 and the guide plate 2 5;

[0043] Furthermore, during the rotation of the guide plate 25, it will drive the vibration plate 10 to rotate synchronously, so that the end of the vibration plate 10 will contact the limiting rod 12, and the guide plate 25 is still rotating at this time, causing the vibration plate 10 to begin to bend until it passes through the limiting rod 12. When the vibration plate 10 is separated from the limiting rod 12, the vibration plate 10 will begin to restore its shape under the action of its own material. During this process, the end of the vibration plate 10 will swing, causing the outer wall of the vibration plate 10 to collide with the inner wall of the mounting groove 11, thereby causing the guide plate 25 to start vibrating, further increasing the effect of the guide plate 25 in shaking off the garbage.

[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
