Description

Technical Field

[0001] This utility model belongs to the field of yeast wastewater technology, specifically a yeast wastewater pretreatment device. Background Technology

[0002] In the modern biotechnology industry, yeast, as an important microorganism, is widely used in various fields such as food, brewing, medicine, and feed. With the continuous expansion of yeast production scale and the sustained growth of market demand, the yeast industry has developed rapidly. However, the yeast production process generates a large amount of wastewater, which has a complex composition, containing high concentrations of organic matter, nitrogen, phosphorus, sulfates, and yeast cells.

[0003] Direct discharge of untreated yeast wastewater not only severely pollutes aquatic environments, leading to eutrophication, excessive algae growth, and disruption of the aquatic ecosystem, but also consumes large amounts of dissolved oxygen, causing aquatic organisms to die from oxygen deprivation. Furthermore, high concentrations of organic wastewater can produce a pungent odor, affecting surrounding air quality and the living environment of residents.

[0004] Therefore, this utility model provides a yeast wastewater pretreatment device. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background technology, a yeast wastewater pretreatment device is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A yeast wastewater pretreatment device of this utility model includes a treatment chamber; the inner wall of the treatment chamber is provided with a limiting component, a filter component, a lifting mechanism, a driving mechanism, a drainage component, and a storage mechanism; the limiting component includes a fixed base plate and limiting rods; two sets of fixed base plates are fixedly installed on both sides of the inner wall of the treatment chamber; several sets of limiting rods are horizontally fixedly installed on the top of the fixed base plate; the cooperation of the fixed base plate and the limiting rods ensures that the first filter screen remains stable during ascent, preventing it from shaking or tilting, and guaranteeing stable ascent of the first filter screen.

[0007] Preferably, the filtration assembly includes a first filter and a second filter. The first filter is slidably installed on the inner wall of the processing chamber, located on top of the fixed base plate and movably connected to the fixed base plate. The first filter is slidably installed on the surface of the limiting rod. The second filter is fixedly installed on the inner wall of the processing chamber, located below the first filter. In this design, the first filter can filter out larger impurities in the yeast wastewater, ensuring that the impurities in the wastewater are fully screened out. The second filter can perform secondary filtration on the yeast wastewater, filtering out the vast majority of impurities, further ensuring treatment efficiency.

[0008] Preferably, the lifting mechanism includes a toothed plate, a shaft bracket, a drive shaft, and a drive gear. The toothed plate is slidably mounted on one side of the inner wall of the processing chamber, and the side of the toothed plate away from the processing chamber is fixedly mounted to the first filter screen. The shaft bracket is fixedly mounted on the top of the processing chamber near the toothed plate, and the inner wall of the shaft bracket is rotatably mounted to the drive shaft. One end of the drive shaft is fixedly mounted to the drive gear, and the drive gear meshes with the toothed plate. In this design, the cooperation between the toothed plate and the drive gear enables the lifting and lowering of the first filter screen through the rotation of the drive shaft, allowing the user to quickly clean the first filter screen and improve filtration efficiency. The cooperation between the shaft bracket and the drive shaft enables the transmission function.

[0009] Preferably, the drive mechanism includes a support frame, a motor, a worm gear, and a worm. The support frame is fixedly installed on the top of the processing chamber near the shaft frame. The inner wall of the support frame is fixedly installed with the motor. The output end of the motor is fixedly installed with the worm. The worm gear is fixedly installed on the end of the transmission shaft away from the drive gear. The worm gear meshes with the worm. In this design, the cooperation between the support frame and the motor can drive the worm to rotate, which in turn drives the worm gear to rotate. At the same time, the worm gear and the worm can achieve a self-locking function, so that the first filter screen can be suspended at any height, and the first filter screen can also be removed.

[0010] Preferably, the drainage assembly includes an outlet pipe and a water pump. The outlet pipe is fixedly installed on one side of the treatment chamber, and the water pump is fixedly installed on the side of the treatment chamber near the outlet pipe. The input end of the water pump is fixedly installed with the outlet pipe. In this scheme, the combined use of the outlet pipe and the water pump can draw out the relatively clean water after sedimentation inside the treatment chamber, so that the yeast wastewater inside the treatment chamber can achieve solid-liquid separation.

[0011] Preferably, the storage mechanism includes a storage box, a baffle, a handle, and a sealing strip. The storage box is slidably installed on the bottom of the inner wall of the processing chamber. One side of the storage box is fixedly installed to the baffle, the side of the baffle away from the storage box is fixedly installed to the handle, and the top of the baffle is fixedly installed to the sealing strip. In this design, the combined use of the storage box, baffle, and handle can store unfilterable sediments in the settled yeast wastewater. After the water pump extracts the water, the user can quickly remove and process the sediments. The sealing strip can provide a seal for the baffle, so that water inside the processing chamber will not leak when the baffle is closed.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The yeast wastewater pretreatment equipment of this utility model, through the setting of a fixed base plate and a limiting rod, enables the first filter screen to remain stable during its ascent, preventing it from shaking or tilting, and ensuring that the first filter screen rises stably.

[0014] 2. The yeast wastewater pretreatment equipment of this utility model, through the setting of a first filter and a second filter, enables the first filter to filter out larger impurities in the yeast wastewater, so that the impurities in the wastewater can be fully screened out, and the second filter can perform secondary filtration of the yeast wastewater and filter out the vast majority of impurities, further ensuring treatment efficiency.

Several sets of limiting rods 22 are horizontally fixedly installed on the top of the fixed base plate 21; the filter assembly 3 includes a first filter screen 31 and a second filter screen 32. The first filter screen 31 is slidably installed on the inner wall of the processing chamber 1. The first filter screen 31 is located on the top of the fixed base plate 21 and is movably connected to the fixed base plate 21. The first filter screen 31 is slidably installed on the surface of the limiting rods 22. The second filter screen 32 is fixedly installed on the inner wall of the processing chamber 1. The second filter screen 32 is located below the first filter screen 31. The lifting mechanism 4 includes a toothed plate 41, a shaft frame 42, a drive shaft 43, and a drive gear 44. The toothed plate 41 is slidably installed on one side of the inner wall of the processing chamber 1. The toothed plate 41 is located away from the... One side of the processing chamber 1 is fixedly installed with the first filter screen 31. The shaft bracket 42 is fixedly installed on the top of the processing chamber 1 near the toothed plate 41. The inner wall of the shaft bracket 42 is rotatably installed with the drive shaft 43. One end of the drive shaft 43 is fixedly installed with the drive gear 44, which meshes with the toothed plate 41. The drive mechanism 5 includes a support frame 51, a motor 52, a worm gear 53, and a worm 54. The support frame 51 is fixedly installed on the top of the processing chamber 1 near the shaft bracket 42. The inner wall of the support frame 51 is fixedly installed with the motor 52. The output end of the motor 52 is fixedly installed with the worm 54. The worm gear 53 is fixedly installed on the drive shaft 43 away from the drive gear 44. Driven at one end, the worm gear 53 meshes with the worm 54. The drainage assembly 6 includes a water outlet pipe 61 and a water pump 62. The water outlet pipe 61 is fixedly installed on one side of the processing chamber 1, and the water pump 62 is fixedly installed on the side of the processing chamber 1 near the water outlet pipe 61. The input end of the water pump 62 is fixedly installed with the water outlet pipe 61. The storage mechanism 7 includes a storage box 71, a baffle 72, a handle 73, and a sealing strip 80. The storage box 71 is slidably installed on the bottom of the inner wall of the processing chamber 1. One side of the storage box 71 is fixedly installed with the baffle 72. The side of the baffle 72 away from the storage box 71 is fixedly installed with the handle 73. The top of the baffle 72 is fixedly installed with the sealing strip 80.

[0026] like Figures 1 to 5As shown, the cooperation between the fixed base plate 21 and the limiting rod 22 ensures that the first filter screen 31 remains stable during its ascent, preventing it from shaking or tilting. This ensures stable ascent of the first filter screen 31, which filters out larger impurities in the yeast wastewater, allowing for thorough screening. The second filter screen 32 performs secondary filtration on the yeast wastewater, removing the vast majority of impurities and further enhancing processing efficiency. The cooperation between the toothed plate 41 and the drive tooth 44 enables the first filter screen 31 to rise and fall via the rotation of the drive shaft 43, allowing users to quickly clean the first filter screen 31 and improving filtration efficiency. The cooperation between the shaft frame 42 and the drive shaft 43 enables transmission. The cooperation between the support frame 51 and the motor 52... The worm gear 54 is driven to rotate, which in turn drives the worm wheel 53 to rotate. At the same time, the worm wheel 53 and the worm gear 54 can achieve a self-locking function, so that the first filter screen 31 can be suspended at any height. The first filter screen 31 can also be removed. The water outlet pipe 61 and the water pump 62 work together to draw out the relatively clean water after sedimentation inside the treatment chamber 1, so that the yeast wastewater inside the treatment chamber 1 can achieve solid-liquid separation. The storage box 71, baffle 72 and handle 73 work together to store the sediment that cannot be filtered in the settled yeast wastewater. After the water pump 62 draws out the water, the user can quickly take out and process the sediment. The sealing strip 80 can provide a seal for the baffle 72, so that the water inside the treatment chamber 1 will not leak when the baffle 72 is closed.

[0027] Working principle: During operation, the processing chamber 1 is first placed on a flat surface, and then the yeast wastewater is poured into the processing chamber 1. When the yeast wastewater enters the processing chamber 1, the first filter screen 31 filters out the larger impurities. Then, the second filter screen 32 performs a second filtration to keep the yeast wastewater relatively clean. When the yeast wastewater flows to the bottom of the inner wall of the processing chamber 1, it is left to stand for about 30 minutes to allow the impurities in the wastewater to settle in the storage box 71. After sedimentation, the water pump 62 is started to pump the clean water that has settled out of the processing chamber 1. Then, the user pulls the handle 73 to pull out the baffle 72 and the storage box 71, and pours out the waste that has settled inside the storage box 71. When it is necessary to clean the first filter screen 31, the motor 52 is started to drive the worm gear 54 to rotate. The rotation of the worm gear 54 will drive the worm wheel 53 to rotate. The rotation of the worm wheel 53 will drive the transmission shaft 43 to rotate. The rotation of the transmission shaft 43 will cause the active gear 44 to rotate. When the active gear 44 rotates, it can make the tooth plate 41 rise. When the tooth plate 41 rises, the first filter screen 31 will move synchronously with it and slide on the surface of the limiting rod 22.
