Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a device for preparing a sulfur-based composite material biological carrier for wastewater denitrification. Background Technology

[0002] Sulfur-based composite biological carriers are made of sulfur compounds and biomass materials. Their function is to use sulfur-autotrophic denitrifying bacteria to reduce nitrates in wastewater to nitrogen gas. At the same time, the porous structure enhances the attachment and mass transfer efficiency, achieving efficient denitrification and reducing operating costs.

[0003] When preparing sulfur-based composite biological carriers, workers need to mix and stir sulfur compound particles and biomass material particles. However, both sulfur compounds and biomass materials are divided into two types: large and small particles. Large sulfur compound and biomass material particles have high compressive strength and bulk modulus, which can provide a stable three-dimensional skeleton structure for biological carriers. They are suitable for biological filter carriers that require long-term stable operation, such as wastewater denitrification. However, the small particles mixed in do not have the advantages of the large particles, which will lead to a decrease in the overall quality of the product. Sometimes, workers will use screening equipment to remove small particles. However, the screening equipment and the stirring equipment are independent of each other. Workers need to transfer the product between the various devices, which is not integrated enough and affects work efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for preparing a sulfur-based composite material biological carrier for wastewater denitrification, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a device for preparing a sulfur-based composite material biocarrier for wastewater denitrification, comprising a support frame, a turntable mounted on the top of the support frame, a rotating shell mounted on the top of the turntable, a stirring cylinder disposed inside the rotating shell, a screening mechanism disposed between the rotating shell and the stirring cylinder, a stirring mechanism disposed inside the stirring cylinder, the turntable being used to pull the rotating shell to rotate around its own axis, the stirring cylinder being used to load granular sulfur compounds and biomass materials, the screening mechanism being used to pull the stirring cylinder to vibrate thereby separating and removing small particles from the sulfur compounds and biomass materials, and the stirring mechanism being used to stir and mix the sulfur compounds and biomass material particles inside the stirring cylinder.

[0006] Preferably, the screening mechanism includes a fixed ring and a receiving frame. The fixed ring is fixedly installed on the surface of the stirring drum, and the receiving frame is fixedly connected to the inner wall of the rotating shell. Rollers are rotatably installed on the receiving frame.

[0007] Preferably, the top of the fixing ring is provided with a concave arc surface, and multiple concave arc surfaces are evenly distributed, with a convex arc surface provided between two adjacent concave arc surfaces.

[0008] Preferably, a guide block is fixedly connected to the surface of the stirring drum, and multiple guide blocks are evenly arranged. A guide rod is fixedly connected to the support frame, and multiple guide rods are arranged corresponding to the guide blocks. The guide block is sleeved on the surface of the guide rod, and a compression spring is sleeved on the surface of the guide rod. The elastic force of the compression spring drives the guide block to move vertically upward.

[0009] Preferably, the stirring mechanism includes a fixed tube, which is disposed at the center inside the stirring drum. The bottom end of the fixed tube is fixedly connected to the stirring drum. Separation holes are densely arranged at the bottom of the stirring drum. A feed inlet is provided at the top of the rotating shell. A rotating rod is rotatably installed at the center inside the fixed tube. A rotating assembly is also provided inside the fixed tube. Multiple rotating assemblies are evenly arranged in the vertical direction.

[0010] Preferably, a mounting shell is fixedly connected to the top of the fixed tube, and a transmission rod is rotatably installed inside the mounting shell. One end of the transmission rod is fixedly connected to a bevel gear, and the other end of the transmission rod passes through the inner wall of the mounting shell and extends outward.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Sulfur compound particles and biomass material particles can be fed into the mixing drum. The turntable drives the rotating shell to rotate around its own axis, and the rollers continuously move between the concave and convex arc surfaces. The mixing drum vibrates continuously in the vertical direction. During the vibration, large sulfur compound and biomass material particles cannot pass through the separation hole and remain inside the mixing drum. At the same time, the blades rotate around the axis of the rotating rod. This invention solves the shortcomings of the prior art, automatically guiding small sulfur compound and biomass material particles through the separation hole and outputting them outward, thus improving product quality. While discharging small sulfur compound and biomass material particles, the blades stir large sulfur compound and biomass material particles, ensuring the uniformity of mixing. Moreover, the entire process is highly integrated and automated, improving work efficiency. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The apparatus for preparing a sulfur-based composite material biological carrier for wastewater denitrification involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] This invention provides a device for preparing a sulfur-based composite material biocarrier for wastewater denitrification, comprising a support frame 1, a turntable 2 mounted on top of the support frame 1, a rotating shell 3 mounted on top of the turntable 2, a stirring drum 4 disposed inside the rotating shell 3, a screening mechanism 5 disposed between the rotating shell 3 and the stirring drum 4, and a stirring mechanism 6 disposed inside the stirring drum 4. The turntable 2 is used to pull the rotating shell 3 to rotate around its own axis, the stirring drum 4 is used to load granular sulfur compounds and biomass materials, the screening mechanism 5 is used to pull the stirring drum 4 to vibrate, thereby separating and removing small particles from the sulfur compounds and biomass materials, and the stirring mechanism 6 is used to stir and mix the sulfur compounds and biomass material particles inside the stirring drum 4.

[0026] Furthermore, the screening mechanism 5 includes a fixed ring 51 and a receiving frame 52. The fixed ring 51 is fixedly installed on the surface of the mixing drum 4, and the receiving frame 52 is fixedly connected to the inner wall of the rotating shell 3. A roller 53 is rotatably installed on the receiving frame 52. The top of the fixed ring 51 is provided with a concave arc surface 511, and multiple concave arc surfaces 511 are evenly arranged. A convex arc surface 512 is provided between two adjacent concave arc surfaces 511. A guide block 54 is fixedly connected to the surface of the mixing drum 4, and multiple guide blocks 54 are evenly arranged. A guide rod 55 is fixedly connected to the support frame 1, and multiple guide rods 55 are provided corresponding to the guide blocks 54. The guide blocks 54 are sleeved on the surface of the guide rods 55, and the guide blocks 54 and the guide rods 55 form a sliding guide fit along the axial direction of the guide rods 55. A compression spring 56 is sleeved on the surface of the guide rods 55, and the elastic force of the compression spring 56 drives the guide blocks 54 to move vertically upward.

[0027] Turntable 2 can drive rotating shell 3 to rotate around its own axis. At the same time, roller 53 rotates synchronously around the axis of rotating shell 3. When roller 53 rotates from concave arc surface 511 to convex arc surface 512, under the compression of roller 53, fixed ring 51 and stirring cylinder 4 move vertically downward as a whole. Guide block 54 moves vertically downward synchronously along guide rod 55. Compression spring 56 increases its elasticity under the action of guide block 54. When roller 53 rotates from convex arc surface 512 to concave arc surface 511, the elasticity of compression spring 56 is released and drives stirring cylinder 4 to move vertically upward. This cycle repeats, and stirring cylinder 4 vibrates continuously in the vertical direction.

[0028] Furthermore, the stirring mechanism 6 includes a fixed tube 61, which is located at the center of the stirring drum 4. The bottom end of the fixed tube 61 is fixedly connected to the stirring drum 4. Separation holes 41 are densely arranged at the bottom of the stirring drum 4. A feed inlet 31 is provided at the top of the rotating shell 3. A rotating rod 63 is rotatably installed at the center of the fixed tube 61. A rotating assembly 62 is also provided inside the fixed tube 61. Multiple rotating assemblies 62 are evenly arranged in the vertical direction. A mounting shell 64 is fixedly connected to the top of the fixed tube 61. A transmission rod 65 is rotatably installed inside the mounting shell 64. One end of the transmission rod 65 is fixedly connected to a bevel gear 67, and the other end of the transmission rod 65 passes through the mounting shell 64. The inner wall extends outward, and a spur gear 66 is fixedly connected to the other end of the transmission rod 65. An L-shaped rod 11 is fixedly connected to the support frame 1, and a rack 69 is fixedly connected to one end of the L-shaped rod 11. The spur gear 66 meshes with the rack 69. A bevel gear 68 is fixedly connected to the surface of the rotating rod 63. The bevel gear 68 meshes with the bevel gear 67. While the stirring drum 4 vibrates in the vertical direction, the spur gear 66 moves along the rack 69. With the cooperation of the rack 69 and the spur gear 66, the transmission rod 65 rotates synchronously around its own axis. The bevel gear 67 and the bevel gear 68 cooperate to convert the rotational force of the transmission rod 65 into the rotational force of the rotating rod 63.

[0029] Furthermore, the rotating assembly 62 includes a bevel gear 3 621 and a rotating rod 622. Each rotating assembly 62 includes four rotating rods 622. The bevel gear 3 621 is fixedly mounted on the surface of the rotating rod 63. The rotating rods 622 are rotatably mounted on the fixed tube 61. One end of the rotating rod 622 extends into the interior of the fixed tube 61. A bevel gear 4 624 is fixedly connected to one end of the rotating rod 622. The bevel gear 4 624 meshes with the bevel gear 3 621. A blade 623 is fixedly connected to the surface of the rotating rod 622. The bevel gear 3 621 and the bevel gear 4 624 cooperate with each other to convert the rotational force of the rotating rod 63 into the rotational force of the rotating rod 622.

[0030] The working principle of this utility model is as follows: Sulfur compound particles and biomass material particles are fed into the mixing drum 4 through the feed inlet 31. The turntable 2 drives the rotating shell 3 to rotate around its own axis. At the same time, the roller 53 rotates synchronously around the axis of the rotating shell 3. When the roller 53 rotates from the concave arc surface 511 to the convex arc surface 512, under the compression of the roller 53, the fixing ring 51 and the mixing drum 4 move vertically downward as a whole. The guide block 54 moves vertically downward synchronously along the guide rod 55. The compression spring 56 increases its elasticity under the action of the guide block 54. When the roller 53 rotates from the convex arc surface 512 to the concave arc surface 511, the elasticity of the compression spring 56 is released and drives the mixing drum 4 to move vertically upward. This cycle repeats, and the mixing drum 4 vibrates continuously in the vertical direction. During the vibration, small sulfur compound and biomass material particles pass through the separation hole 41 and are output outward, while large sulfur compound and biomass material particles cannot pass through the separation hole 41 and remain inside the mixing drum 4.

[0031] While the mixing drum 4 vibrates vertically, the spur gear 66 moves along the rack 69, and with the cooperation of the rack 69 and the spur gear 66, the transmission rod 65 rotates synchronously around its own axis. The rotation of the transmission rod 65 drives the rotating rod 63 to rotate synchronously around its own axis through the first bevel gear 67 and the second bevel gear 68. The rotation of the rotating rod 63 drives the rotating rod 622 to rotate synchronously around its own axis through the third bevel gear 621 and the fourth bevel gear 624. The rotation of the rotating rod 622 drives the blade 623 to rotate synchronously around the axis of the rotating rod 622. During this process, the blade 623 uniformly mixes the large-particle sulfur compounds and biomass materials.
