Description

Technical Field

[0001] The utility model relates to the technical field of sludge storage, and specifically, to an anaerobic granular sludge storage device. Background Technique

[0002] Sludge solid waste resource utilization is a sludge resource utilization disposal technology that uses urban sludge as the main raw material and urban industrial solid waste as the auxiliary material to produce a series of lightweight aggregate products with specific properties through a rotary kiln roasting process. The granules synthesized from sludge solid waste need to be stored and discharged from the storage tank according to the amount used. At the same time, after the production of solid waste granules is completed, they need to be packaged for transportation, which requires a storage device to store the granules.

[0003] The patent with the authorization announcement number CN117139165B provides an anaerobic granular sludge storage device for papermaking sewage treatment, which is provided with a mesh conveyor belt. The mesh conveyor belt enables small-sized granules to fall below the mesh conveyor belt and enter the first storage bin for storage. The mesh conveyor belt can drive large-sized granules to move a set distance and then fall into the second storage bin for storage, which is beneficial to the storage and packaging of granules.

[0004] However, in the above patent, when screening anaerobic granules of different sizes through the mesh conveyor belt, since the large-sized granules staying on the mesh conveyor belt are relatively stationary with respect to the mesh conveyor belt, there is a situation where some small-sized granules accumulate above the large-sized granules and cannot fall below the mesh conveyor belt through the mesh holes of the mesh conveyor belt, resulting in a poor sorting effect of the mesh conveyor belt on anaerobic granules. In view of this, we propose an anaerobic granular sludge storage device. Summary of the Invention

[0005] The purpose of the utility model is to provide an anaerobic granular sludge storage device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, one of the purposes of the utility model is to provide an anaerobic granular sludge storage device, including a storage box. A partition is fixedly connected to the bottom surface inside the storage box. A conveying frame is slidably connected to the position above the partition inside the storage box. Two belt rollers are rotatably connected inside the conveying frame. A leaky mesh conveyor belt is slidably sleeved on the circumferential outer walls of the two belt rollers. A driving mechanism is arranged on one side of the conveying frame. The driving mechanism is used to drive one of the belt rollers to rotate. While the driving mechanism drives the belt roller to rotate, it drives the conveying frame, the belt roller, and the leaky mesh conveyor belt to move vertically back and forth.

[0007] As a further improvement of this technical solution, the driving mechanism includes a vertical shaft rotatably connected to one side of the conveying frame. Bevel gears are fixedly connected to the circumferential outer wall of the vertical shaft and the rotating shaft of one of the belt rollers respectively. The two bevel gears mesh with each other.

[0008] As a further improvement of the technical solution, the driving mechanism further includes a motor fixedly installed on the top of the storage tank. The output shaft of the motor is fixedly connected with a driving disc. Two sliding rods are fixedly connected to the lower surface of the driving disc. The upper end of the vertical shaft is fixedly connected with a driven disc, and one end of the sliding rod penetrates through the side wall of the driven disc.

[0009] As a further improvement of the technical solution, a turntable is fixedly connected to the lower end of the vertical shaft. A pressing rod is eccentrically installed on the lower surface of the turntable. An inclined platform is fixedly connected to the inner wall of the storage tank. One side of the inclined platform is an inclined surface, and the lower end of the pressing rod is in contact with the inclined surface of the inclined platform.

[0010] As a further improvement of the technical solution, four positioning frames are arranged inside the storage tank. Connecting strips are fixedly connected to both ends of the positioning frame. One end of the connecting strip is fixedly connected to the inner wall of the storage tank. A side ear is slidably sleeved on the outer wall of the positioning frame. The side ear is fixedly connected to one side of the conveying frame. Springs are sleeved on the positioning frame near both ends. One end of the spring is fixedly connected to the connecting strip, and the other end of the spring is fixedly connected to the side ear.

[0011] As a further improvement of the technical solution, outlets are symmetrically arranged on both sides of the conveying frame. A guide plate is fixedly connected to the bottom surface inside the two outlets. The guide plate is of an inverted V-shaped structure, and the leaky net conveyor belt is movably sleeved on the outside of the guide plate.

[0012] As a further improvement of the technical solution, a first storage bin is arranged between the left side of the partition plate and the inner wall of the storage tank, and a second storage bin is arranged between the right side of the partition plate and the inner wall of the storage tank. The two belt rollers are respectively located above the first storage bin and the second storage bin.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] For this anaerobic granular sludge storage device, after the anaerobic granules to be stored are conveyed to the upper horizontal section of the leaky net conveyor belt located above the second storage bin, the leaky net conveyor belt moves vertically up and down while running, vibrating and screening the anaerobic granules on the leaky net conveyor belt, improving the sorting effect of the leaky net conveyor belt on the anaerobic granules. The anaerobic granules with smaller volume fall into the second storage bin through the mesh holes of the leaky net conveyor belt, and the anaerobic granules with larger volume are conveyed by the leaky net conveyor belt into the first storage bin, storing the anaerobic granules classified by particle size, which is beneficial to the storage and sub-packaging of the granules.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0024] Please refer to Figures 1 - 4As shown in the figure, this embodiment provides an anaerobic granular sludge storage device, which includes a storage tank 1. A partition plate 2 is fixedly connected to the bottom surface inside the storage tank 1. A conveying rack 3 is slidably connected to the position above the partition plate 2 inside the storage tank 1. The conveying rack 3 can only move vertically inside the storage tank 1. Two belt rollers 4 are rotatably connected inside the conveying rack 3. Exits are symmetrically arranged on both sides of the conveying rack 3. The bottom surfaces inside the two exits are fixedly connected with guide plates 9. The guide plates 9 are arranged on one side of the partition plate 2. The space between the side of the partition plate 2 away from the guide plate 9 and the inner wall of the storage tank 1 is set as the first storage bin, and the space between the side of the partition plate 2 close to the guide plate 9 and the inner wall of the storage tank 1 is set as the second storage bin. A leaky conveyor belt 5 is slidably sleeved on the circumferential outer walls of the two belt rollers 4. The guide plate 9 is of an inverted V-shaped structure and is arranged inside the leaky conveyor belt 5. When the anaerobic granules to be stored are conveyed to the upper horizontal section of the leaky conveyor belt 5 directly above the second storage bin through an external conveying device, the smaller anaerobic granules fall through the mesh holes of the leaky conveyor belt 5 onto the guide plate 9 and slide down through the outlet along the inclined surface of the guide plate 9 into the inside of the second storage bin. The larger anaerobic granules remain above the leaky conveyor belt 5. A driving mechanism 6 is arranged on one side of the conveying rack 3. The driving mechanism 6 is used to drive one of the belt rollers 4 to rotate. Let the driving mechanism 6 drive one of the belt rollers 4 to rotate, so that the belt roller 4 drives the leaky conveyor belt 5 to operate, and the leaky conveyor belt 5 conveys the larger anaerobic granules above the first storage bin, so that the larger anaerobic granules fall from the leaky conveyor belt 5 into the inside of the first storage bin for storage, classifying and storing the anaerobic granules according to the particle size, which is beneficial to the storage and packaging of the granules.

[0025] In order to enable the driving mechanism 6 to drive one of the belt rollers 4 to rotate, the following refines some structures of the driving mechanism 6. The driving mechanism 6 includes a vertical shaft 61 rotatably connected to one side of the conveying rack 3. Bevel gears 62 are fixedly connected to the circumferential outer wall of the vertical shaft 61 and the rotating shaft of one of the belt rollers 4 respectively. The two bevel gears 62 are meshed with each other. When the vertical shaft 61 drives one of the bevel gears 62 to rotate, through the meshing transmission of the two bevel gears 62, the other bevel gear 62 drives one of the belt rollers 4 to rotate, and then the belt roller 4 drives the leaky conveyor belt 5 to operate to convey the anaerobic granules.

[0026] When the driving mechanism 6 drives one of the belt rollers 4 to rotate, that is, when the vertical shaft 61 rotates, the conveying frame 3, the belt roller 4 and the screen conveyor belt 5 move vertically back and forth, vibrating and screening the anaerobic granules on the horizontal section of the screen conveyor belt 5 to improve the sorting effect of the screen conveyor belt 5 on the anaerobic granules. The following further details the remaining structure of the driving mechanism 6. The driving mechanism 6 further includes a motor 66 fixedly installed on the top of the storage tank 1. The output shaft of the motor 66 is fixedly connected with a driving disc 64. Two sliding rods 65 are fixedly connected to the lower surface of the driving disc 64. The upper end of the vertical shaft 61 is fixedly connected with a driven disc 63. One end of the sliding rod 65 penetrates through the side wall of the driven disc 63. When the output shaft of the motor 66 drives the driving disc 64 to rotate, the driving disc 64 drives the two sliding rods 65 to rotate. By the force of the rotation of the two sliding rods 65, the two sliding rods 65 drive the driven disc 63 and the vertical shaft 61 to rotate. The lower end of the vertical shaft 61 is fixedly connected with a turntable 67. A push rod 68 is eccentrically installed on the lower surface of the turntable 67. The inner wall of the storage tank 1 is fixedly connected with an inclined platform 69. One side of the inclined platform 69 is an inclined surface. The lower end of the push rod 68 is in contact with the inclined surface of the inclined platform 69. When the vertical shaft 61 drives the turntable 67 and the push rod 68 to rotate, during the rotation of the push rod 68, it will slide along the inclined side wall of the inclined platform 69. When the push rod 68 moves from the lower part to the upper part of the inclined surface of the inclined platform 69, it will drive the vertical shaft 61 and the conveying frame 3 to move vertically upward. When the push rod 68 moves from the upper part to the lower part of the inclined surface of the inclined platform 69, the vertical shaft 61 and the conveying frame 3 will fall under the action of gravity, causing the push rod 68 to move up and down during the rotation on the inclined surface of the inclined platform 69. During the up and down movement of the push rod 68, it will drive the vertical shaft 61, the conveying frame 3, the belt roller 4 and the screen conveyor belt 5 to move up and down. During the process of the vertical shaft 61 driving the driven disc 63 to move up and down, the driven disc 63 is always slidably connected to the outer walls of the two sliding rods 65, without affecting the driving of the vertical shaft 61 by the motor 66. In this way, the vertical reciprocating movement of the screen conveyor belt 5 is realized, so that the screen conveyor belt 5 vibrates and screens the anaerobic granules while conveying them. The small-sized granules piled on top of the large-sized granules can be vibrated and adjusted in position to pass through the mesh holes of the screen conveyor belt 5, improving the sorting effect of the screen conveyor belt 5 on the anaerobic granules.

[0027] In order to improve the stability of the conveying rack 3 during vertical movement within the storage box 1, four positioning racks 7 are provided inside the storage box 1. Connecting bars are fixedly connected to both ends of the positioning rack 7. One end of the connecting bar is fixedly connected to the inner wall of the storage box 1. A side ear is slidably sleeved on the outer wall of the positioning rack 7, and the side ear is fixedly connected to one side of the conveying rack 3. When the conveying rack 3 moves up and down, the side ear slides along the outer wall of the vertical section of the positioning rack 7, improving the stability of the conveying rack 3 during vertical movement. Springs 8 are sleeved at positions near both ends of the positioning rack 7. One end of the spring 8 is fixedly connected to the connecting bar, and the other end of the spring 8 is fixedly connected to the side ear. By providing the springs 8, when the conveying rack 3 moves vertically downward, the springs 8 undergo elastic deformation to buffer the conveying rack 3, preventing the conveying rack 3 from being damaged due to a large impact force during the downward movement.

[0028] In summary, the working principle of this solution is as follows: The anaerobic granules to be stored are continuously conveyed to the upper horizontal section of the mesh belt conveyor 5 directly above the second storage bin through an external conveying device. The motor 66 is started to make the mesh belt conveyor 5 move vertically up and down while running, vibrating and screening the anaerobic granules on the mesh belt conveyor 5. The smaller anaerobic granules fall through the mesh holes of the mesh belt conveyor 5 onto the guide plate 9 and slide down along the inclined surface of the guide plate 9 through the outlet into the interior of the second storage bin. The larger anaerobic granules remain above the mesh belt conveyor 5 until they are conveyed into the interior of the first storage bin by the mesh belt conveyor 5, classifying and storing the anaerobic granules according to particle size to facilitate the storage and packaging of the granules.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
