A sewage deodorization device for sewage treatment plants

Abstract

This utility model discloses a wastewater deodorization device for wastewater treatment plants, including a sedimentation tank and an inlet pipe disposed on the side of the sedimentation tank. The top of the sedimentation tank has an opening, and a swing assembly is fixedly installed on the top of the opening. A stirring assembly and a feeding assembly are fixedly installed outside the swing assembly. The swing assembly includes ear plates fixedly connected to the front and rear sides of the opening on the top of the sedimentation tank. An installation plate is movably hinged inside the ear plates. This wastewater deodorization device for wastewater treatment plants controls a dual-axis motor to drive a turntable to rotate. An eccentric rod rotates with the turntable, causing a support rod to move outside the turntable. The support rod drives a rack to slide back and forth inside a guide rail. The sliding of the rack drives a gear to rotate back and forth, which in turn drives the installation plate to move back and forth around the inner side of the ear plates. This causes the stirring assembly to swing back and forth within the sedimentation tank, expanding the stirring range and improving deodorization efficiency.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater deodorization device for wastewater treatment plants. Background Technology

[0002] Wastewater treatment plants are facilities used to treat wastewater generated in cities, industries, and rural areas. Through a series of complex unit processes, such as physical treatment, biochemical treatment, and advanced treatment, wastewater treatment plants remove pollutants such as suspended solids, ammonia nitrogen, phosphorus, and bacteria from wastewater to meet discharge standards. Wastewater treatment is involved in many industrial production processes and is related to whether an industrial manufacturer can produce green products. Among the many stages of wastewater treatment, the initial sedimentation step produces the most odors, so deodorization treatment is often required during sedimentation.

[0003] Existing patent number CN213388092U discloses a sewage deodorization device for sewage treatment plants. The device uses a motor to drive a rotating shaft to rotate, which in turn drives a rotating disk to rotate. When the rotating disk rotates, a fixed pin continuously pushes a swing rod, causing the swing rod to swing back and forth. At the same time, the spiral conveyor blades can drive the sludge to tumble up and down. The swinging of the swing rod also makes it easier to react the deodorizing agent or deodorizing sludge with the sewage in the sedimentation tank, thereby improving the deodorization efficiency of the sewage sedimentation tank.

[0004] In the aforementioned patent, the sludge is driven to tumble back and forth by a spiral conveyor blade, and the swing rod swings back and forth to ensure mixing. However, the position of the motor and the rotating shaft is fixed, and it cannot swing back and forth, resulting in a small range of tumbling of the sewage and a reduction in mixing efficiency. At the same time, the addition position of deodorizing agents is fixed, and they are added together, which cannot be quickly and evenly dispersed into the sewage, thus reducing the deodorization efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a wastewater deodorization device for wastewater treatment plants, thereby expanding the mixing range and dispersing the deodorizing agent to improve deodorization efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater deodorization device for a wastewater treatment plant, comprising a sedimentation tank and an inlet pipe disposed on the side of the sedimentation tank. The sedimentation tank has an opening at its top, and a swing assembly is fixedly installed at the top of the opening. A stirring assembly and a feeding assembly are fixedly installed outside the swing assembly. The swing assembly includes ear plates fixedly connected to the front and rear sides of the opening at the top of the sedimentation tank. An mounting plate is movably hinged inside the ear plates. Gears are fixedly installed on the front and rear sides of the mounting plate, located outside the ear plates. A guide rail corresponding to the gears is fixedly installed at the top of the sedimentation tank. A rack meshing with the gears is movably installed inside the guide rail. A support rod is movably hinged to the left side of the rack. A dual-shaft motor is fixedly installed on the left side of the top of the sedimentation tank. A turntable is fixedly installed outside the output shaft of the dual-shaft motor. An eccentric rod is fixedly installed outside the turntable. The support rod is movably hinged to the outside of the eccentric rod.

[0007] Preferably, the bottom of the rack is provided with a retaining strip corresponding to the guide rail.

[0008] Preferably, the rack is symmetrically arranged on both the front and rear sides of the ear plate.

[0009] Preferably, a support frame is fixedly installed on the top of the sedimentation tank, and the dual-shaft motor is fixedly mounted on the support frame.

[0010] Preferably, the stirring assembly includes a drive motor fixedly mounted on the top of the mounting plate, a rotating shaft located in the sedimentation tank fixedly connected to the bottom of the output shaft of the drive motor, a spiral conveying blade fixedly mounted on the outside of the rotating shaft, a stirring frame fixedly mounted on the bottom of the rotating shaft, and stirring blades fixedly mounted on the outside of the stirring frame.

[0011] Preferably, the feeding assembly includes a cylinder, which is fixedly installed inside the mounting plate. The bottom of the cylinder has a discharge port, and the top of the cylinder is fixedly installed with a second drive motor. The output shaft of the second drive motor is fixedly connected to a feeding auger located inside the cylinder, and the side of the cylinder is fixedly connected to a feeding channel.

[0012] Preferably, a rubber strip that fits against the inner wall of the cylinder is fixedly installed along the edge of the feeding auger.

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

[0014] 1. By controlling the dual-axis motor to drive the turntable to rotate, the eccentric rod moves with the turntable to move the support rod outside the turntable. The support rod drives the rack to slide back and forth inside the guide rail. In turn, the sliding of the rack drives the gear to rotate back and forth. The gear drives the mounting plate to move back and forth around the inner side of the ear plate. This causes the stirring component to swing back and forth in the sedimentation tank, expanding the stirring range and improving the deodorization efficiency.

[0015] 2. By driving the second motor to rotate the feeding auger inside the cylinder, the deodorizer can be evenly squeezed out from the outlet and fall into the sedimentation tank, realizing the quantitative and dispersed addition of the deodorizer. This not only improves work efficiency, but also ensures that the deodorizer and sewage are fully mixed, further enhancing the deodorization effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a wastewater deodorization device for a wastewater treatment plant, comprising a sedimentation tank 1 and an inlet pipe 2 disposed on the side of the sedimentation tank 1. An opening 3 is provided at the top of the sedimentation tank 1, and a swing assembly 4 is fixedly installed at the top of the opening 3. A stirring assembly 5 and a feeding assembly 6 are fixedly installed outside the swing assembly 4. The swing assembly 4 includes ear plates 41 fixedly connected to the front and rear sides of the opening 3 at the top of the sedimentation tank 1. An mounting plate 42 is movably hinged inside the ear plates 41. The mounting plate 42 has two sides... A gear 43 is fixedly installed on the outside of the ear plate 41. A guide rail 44 corresponding to the gear 43 is fixedly installed on the top of the sedimentation tank 1. A rack 45 that meshes with the gear 43 is movably installed inside the guide rail 44. A support rod 46 is movably hinged to the left side of the rack 45. A dual-shaft motor 47 is fixedly installed on the left side of the top of the sedimentation tank 1. A turntable 48 is fixedly installed on the outside of the output shaft of the dual-shaft motor 47. An eccentric rod 49 is fixedly installed on the outside of the turntable 48. The support rod 46 is movably hinged to the outside of the eccentric rod 49.

[0024] By controlling the dual-axis motor 47 to drive the turntable 48 to rotate, the eccentric rod 49 rotates with the turntable 48, causing the support rod 46 to move outside the turntable 48. The support rod 46 drives the rack 45 to slide back and forth inside the guide rail 44. In turn, the sliding of the rack 45 drives the gear 43 to rotate back and forth. The gear 43 drives the mounting plate 42 to move back and forth around the inner side of the ear plate 41, causing the stirring assembly 5 to swing back and forth inside the sedimentation tank 1, thus expanding the stirring range and improving the deodorization efficiency.

[0025] The bottom of the rack 45 is provided with a retaining strip corresponding to the guide rail 44. The retaining strip is movably engaged inside the guide rail 44. The retaining strip makes the rack 45 more stable when sliding inside the guide rail 44, preventing the rack 45 from deviating during sliding, further improving the stability of the oscillation of the stirring assembly 5, thereby improving the deodorization efficiency.

[0026] The racks 45 are symmetrically arranged on both sides of the ear plate 41, making the entire transmission mechanism more balanced. The racks 45 on both sides can drive the gears 43 to rotate synchronously, thereby ensuring that the reciprocating oscillation of the stirring assembly 5 in the sedimentation tank 1 is more uniform and avoiding oscillation instability caused by uneven force on one side.

[0027] A support frame is fixedly installed on the top of the sedimentation tank 1. A dual-shaft motor 47 is fixedly mounted on the support frame. The output shaft of the dual-shaft motor 47 passes through the support frame and is fixedly connected to the center of the turntable 48. The output shaft of the dual-shaft motor 47 drives the turntable 48 to rotate. The rotation of the turntable 48 drives the outer support rod 46 to move, thereby realizing the drive of the entire transmission mechanism. The structure is compact and the transmission is stable.

[0028] Please see Figure 4 The stirring assembly 5 includes a drive motor 51 fixedly installed on the top of the mounting plate 42. The bottom of the output shaft of the drive motor 51 is fixedly connected to a rotating shaft 52 located inside the sedimentation tank 1. A spiral conveying blade 53 is fixedly installed on the outside of the rotating shaft 52. A stirring frame 54 is fixedly installed at the bottom of the rotating shaft 52. A stirring blade 55 is fixedly installed on the outside of the stirring frame 54. The drive motor 51 drives the rotating shaft 52 to rotate, and the spiral conveying blade 53 on the outside of the rotating shaft 52 rotates accordingly. This can transport the sediment at the bottom of the sedimentation tank 1 upwards, preventing the sediment from accumulating at the bottom and affecting the deodorization effect. The stirring frame 54 and stirring blade 55 at the bottom of the rotating shaft 52 stir the sewage in the sedimentation tank 1, making the sewage and deodorizing agent mix more evenly and improving the deodorization efficiency. The stirring blade 55 is evenly distributed on the outside of the stirring frame 54, further ensuring the uniformity of stirring.

[0029] Please see Figure 5 The feeding assembly 6 includes a cylinder 61, which is fixedly installed inside the mounting plate 42. The bottom of the cylinder 61 has a discharge port 62, and the top of the cylinder 61 is fixedly installed with a second drive motor 63. The output shaft of the second drive motor 63 is fixedly connected to a feeding auger 64 located inside the cylinder 61. The side of the cylinder 61 is fixedly connected to a feeding channel 65. The second drive motor 63 drives the feeding auger 64 to rotate inside the cylinder 61, which can evenly squeeze the deodorizer out of the discharge port 62 and drop it into the sedimentation tank 1. This realizes the quantitative and dispersed addition of the deodorizer, which not only improves the working efficiency, but also ensures the full mixing of the deodorizer and the sewage, further improving the deodorization effect.

[0030] A rubber strip is fixedly installed along the edge of the feeding auger 64 to fit the inner wall of the cylinder 61. The rubber strip not only increases the friction between the feeding auger 64 and the inner wall of the cylinder 61, preventing slippage during rotation and ensuring stable delivery of the deodorant, but also reduces direct friction between the feeding auger 64 and the inner wall of the cylinder 61, extending the service life of the equipment. The rubber strip also has a certain degree of elasticity, which can provide a certain buffering effect when the feeding auger 64 rotates, reducing the noise generated during equipment operation and improving the overall working environment.

[0031] Working principle: Wastewater is added to the sedimentation tank 1 through the inlet pipe 2. Then, deodorant is added to the cylinder 61 through the feeding channel 65. The rubber strip on the side of the feeding auger 64 is attached to the inner wall of the cylinder 61 to ensure the seal at the connection. The dual-shaft motor 47 drives the turntables 48 on the front and rear sides to rotate. The eccentric rod 49 moves with the turntables 48, causing the support rod 46 to move outside the turntables 48. The support rod 46 drives the rack 45 to slide back and forth inside the guide rail 44. The sliding of the rack 45 drives the gear 43 to rotate back and forth. The gear 43 drives the mounting plate 42 to move back and forth around the inner side of the ear plate 41. The drive motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the spiral conveyor blade 53, the stirring frame 54 and the stirring blade 55 inside the sedimentation tank 1 to rotate. The rotating shaft 52 swings back and forth with the mounting plate 42, thereby expanding the agitation range of the wastewater and improving the mixing efficiency of the deodorant.

[0032] The reciprocating motion of the mounting plate 42 drives the cylinder 61 to reciprocate. During this process, the slower-speed drive motor 63 drives the feeding auger 64 to rotate, causing the deodorizing agent to be conveyed downwards within the cylinder 61 and evenly distributed into the sedimentation tank 1. This expands the distribution range of the deodorizing agent, prevents it from concentrating, and improves the deodorization mixing efficiency.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
