Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for treating silage wastewater with yeast. Background Technology

[0002] In recent years, silage has been widely used in animal husbandry due to its ability to preserve the excellent quality of green fodder under adverse conditions. Silage is preserved under sealed conditions through the fermentation activity of lactic acid bacteria, which lowers the pH value. In conventional silage preparation, a certain moisture content in the raw materials must be maintained to facilitate lactic acid bacteria activity. However, high moisture content in the raw materials, coupled with mechanical processing, can generate a large amount of plant juice, exceeding the plant's own absorption capacity and causing silage exudate.

[0003] In the treatment of silage wastewater, a yeast-based wastewater treatment device is needed. Chinese utility model patent CN219752066U discloses such a device, comprising: a wastewater storage tank, a yeast reactor, a sedimentation tank, and an effluent tank. The wastewater storage tank, yeast reactor, and sedimentation tank are connected sequentially. The supernatant outlet of the sedimentation tank is connected to the effluent tank, and the sludge outlet of the sedimentation tank is divided into two paths: one for external discharge and the other connected to the yeast reactor. Using this device, pollutants in the wastewater are removed, and excess yeast can be used to produce cell proteins, turning waste into a valuable resource.

[0004] However, the amount of yeast added in the yeast treatment device for silage wastewater of this utility model is difficult to control precisely. Adding too much will cause waste, while adding too little will not achieve the desired treatment effect, resulting in uneven mixing of wastewater and yeast, which affects the degradation efficiency of organic matter. Therefore, a yeast treatment device for silage wastewater is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a yeast-based device for treating silage wastewater, which has advantages such as good treatment effect and solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A yeast treatment device for silage wastewater includes a treatment tank, a purification tank fixedly connected to the top of the treatment tank, an inlet pipe fixedly connected to the top of the purification tank, and an outlet pool located outside the purification tank. The purification tank is provided with a stirring mechanism extending into it for stirring the filtered wastewater, and the purification tank is provided with a conveying structure for quantitatively adding yeast according to the stirring speed.

[0008] The stirring mechanism includes a motor base fixedly connected to the outside of the processing tank and a stirring shaft rotatably connected to the inside of the processing tank and extending to the outside. A drive motor is fixedly installed inside the motor base, a transmission gear is fixedly connected to the output shaft of the drive motor, a driven gear meshing with the transmission gear is fixedly connected to the outside of the stirring shaft, and a stirring rod is fixedly connected to the outside of the stirring shaft.

[0009] The conveying structure includes a suction structure and a synchronization structure.

A pulley is rotatably connected to the outside of the rotating disk, and the swing rod is slidably connected to the outside of the pulley.

[0010] Furthermore, the processing box is internally fixedly equipped with a bearing adapted to the stirring shaft, and there are several stirring rods, which are distributed at equal intervals on the outside of the stirring shaft.

[0011] Furthermore, the swing rod has a groove inside that matches the pulley, and the outer diameter of the pulley matches the inner diameter of the groove. The swing rod is connected to the outside of the rotating disk by reciprocating swinging through the pulley.

[0012] Furthermore, a storage box is fixedly connected to the outside of the purification box, and a liquid filling port is provided on the outside of the storage box. A sealing plug is detachably connected to the outside of the liquid filling port.

[0013] Furthermore, the suction structure includes a piston cylinder fixedly connected to the outside of the processing box and a connecting lug fixedly connected to the outside of the swing rod. A stopper plate is slidably connected inside the piston cylinder, and a stopper rod is fixedly connected between the stopper plate and the connecting lug.

[0014] Furthermore, a conveying pipe is fixedly connected between the piston cylinder and the processing box, and an extraction pipe is fixedly connected between the piston cylinder and the storage box.

[0017] Compared with the prior art, this utility model provides a yeast treatment device for silage wastewater, which has the following beneficial effects:

[0018] 1. This yeast treatment device for silage wastewater uses a drive motor to rotate a transmission gear, which in turn drives a driven gear, a stirring shaft, and a stirring rod to rotate inside the treatment tank. This, in turn, drives the synchronous structure of the conveying structure to work, thereby enabling the suction structure to draw in and add yeast. The stirring speed is linked to the amount of yeast added; the faster the stirring speed, the more yeast is added. The device can precisely control the amount of yeast added according to the actual needs of wastewater stirring, thereby improving the utilization rate of yeast and the wastewater treatment effect, achieving the advantage of good treatment results.

[0019] 2. This yeast-treated silage wastewater treatment device effectively intercepts large particles of different sizes by setting two equally spaced filter frames in the purification tank. This reduces the wear and tear on yeast activity and treatment equipment caused by impurities, extends the service life of the equipment, and improves the efficiency of subsequent treatment stages. By setting up an aeration fan to provide sufficient oxygen for yeast, it is beneficial to the growth and metabolism of yeast, accelerates the decomposition of organic matter in wastewater, improves wastewater treatment efficiency, and shortens the treatment cycle.

[0024] 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.

[0025] Please see Figures 1 to 3The yeast treatment device for silage wastewater in this embodiment includes a treatment tank 1, a purification tank 2 fixedly connected to the top of the treatment tank 1, an inlet pipe 3 fixedly connected to the top of the purification tank 2, and an outlet pool 4 disposed outside the purification tank 2. The purification tank 2 is provided with a stirring mechanism 7 extending into its interior for stirring the filtered wastewater. The purification tank 2 is also provided with a conveying structure 8 for quantitatively adding yeast according to the stirring speed.

[0026] The stirring mechanism 7 includes a motor base 71 fixedly connected to the outside of the processing tank 1 and a stirring shaft 74 rotatably connected to the inside of the processing tank 1 and extending to the outside. A drive motor 72 is fixedly installed inside the motor base 71, and a transmission gear 73 is fixedly connected to the output shaft of the drive motor 72. A driven gear 75 meshing with the transmission gear 73 is fixedly connected to the outside of the stirring shaft 74, and a stirring rod 76 is fixedly connected to the outside of the stirring shaft 74. The stirring mechanism 7 uses the transmission gear 73 and the driven gear 75 for transmission, which has high transmission efficiency, compact structure, and accurate transmission ratio, and can ensure the stable rotation of the stirring shaft 74.

[0027] Specifically, the processing box 1 is fixedly installed with a bearing that is compatible with the stirring shaft 74, and there are several stirring rods 76, which are distributed at equal intervals on the outside of the stirring shaft 74.

[0028] Please see Figures 1 to 3 In this embodiment, the conveying structure 8 includes a suction structure and a synchronization structure. The synchronization structure includes a rotating disk 86 fixedly connected to one end of the stirring shaft 74 and a swing rod 87 rotatably connected to the outside of the processing box 1. A pulley 88 is rotatably connected to the outside of the rotating disk 86, and the swing rod 87 is slidably connected to the outside of the pulley 88.

[0029] The swing rod 87 has an internal groove that matches the pulley 88. The outer diameter of the pulley 88 matches the inner diameter of the groove. The swing rod 87 is connected to the outside of the rotating disk 86 via the pulley 88. A storage box 81 is fixedly connected to the outside of the purification box 2. The storage box 81 has a liquid filling port on its outside, and a sealing plug is detachably connected to the outside of the liquid filling port.

[0030] Specifically, the suction structure includes a piston cylinder 82 fixedly connected to the outside of the treatment tank 1 and a connecting lug 89 fixedly connected to the outside of the swing rod 87. A stopper plate 85 is slidably connected inside the piston cylinder 82, and a stopper rod 810 is fixedly connected between the stopper plate 85 and the connecting lug 89. The stopper rod 810 is slidably connected inside the piston cylinder 82 and extends to its outside. Through the cooperation of the stirring mechanism 7 and the conveying structure 8, the stirring speed and the amount of yeast added are linked. The faster the stirring speed, the greater the need for mixing of wastewater and yeast. At this time, the amount of yeast added also increases accordingly, ensuring sufficient contact and reaction between yeast and wastewater, and improving the degradation efficiency of organic matter.

[0031] It should be noted that a conveying pipe 83 is fixedly connected between the piston cylinder 82 and the processing box 1, and an extraction pipe 84 is fixedly connected between the piston cylinder 82 and the storage box 81.

[0032] Please see Figure 1 In this embodiment, an aeration fan 6 is rotatably connected to the outside of the treatment tank 1. A connecting pipe 9 is fixedly connected between the treatment tank 1 and the effluent tank 4. A solenoid valve is fixedly installed inside the connecting pipe 9. A drain pipe is fixedly connected to the outside of the effluent tank 4. Two filter frames 5 are slidably connected inside the purification tank 2, and the two filter frames 5 are distributed at equal intervals inside the purification tank 2. The solenoid valve in the connecting pipe 9 can conveniently control the discharge of treated wastewater, realizing the automated operation of the device.

[0033] The working principle of the above embodiments is as follows:

[0034] During use, silage wastewater enters the purification tank 2 through the inlet pipe 3. Inside the purification tank 2, the wastewater flows sequentially through two equally spaced filter frames 5. The filter frames 5 can intercept large particulate impurities in the wastewater, such as silt and plant residues, to achieve preliminary filtration of the wastewater and reduce the impact of impurities on subsequent treatment stages. The controller starts the drive motor 72 to drive the transmission gear 73 to rotate. Because the driven gear 75 on the outside of the stirring shaft 74 meshes with the transmission gear 73, the driven gear 75 drives the stirring shaft 74 and the stirring rod 76 to rotate, stirring the wastewater after preliminary filtration and making the wastewater flow, thus creating conditions for the uniform addition of yeast and thorough mixing with the wastewater. The rotating disk 86 at one end of the stirring shaft 74 rotates synchronously with the stirring shaft 74. The pulley 88 on the outside of the rotating disk 86 makes a circular motion around the center of the rotating disk 86. The pulley 88 drives the swing rod 87 to swing back and forth around its rotating connection point with the outside of the treatment tank 1 through the sliding groove. The connecting lug 89 on the outside of the swing rod 87 drives the stop plate 85 to slide back and forth in the piston cylinder 82 through the stop rod 810. When the stop plate 85 slides away from the extraction pipe 84, a negative pressure is formed in the piston cylinder 82, and the yeast liquid in the storage tank 81 moves under the pressure difference. The yeast solution is drawn into the piston cylinder 82 through the extraction pipe 84. When the stopper plate 85 slides towards the extraction pipe 84, the yeast solution in the piston cylinder 82 is pressed into the treatment tank 1 through the delivery pipe 83 under pressure, thus adding yeast. Since the oscillation frequency of the swing rod 87 is related to the rotation speed of the stirring shaft 74, the faster the stirring speed, the higher the oscillation frequency of the swing rod 87, and the faster the reciprocating sliding speed of the stopper plate 85, thereby realizing the quantitative addition of yeast according to the stirring speed. The aeration blower 6 introduces air into the treatment tank 1 to provide sufficient oxygen for the yeast, promote the growth and metabolism of the yeast, and accelerate the degradation of organic matter in the wastewater. The treated wastewater enters the effluent tank 4 through the connecting pipe 9. The solenoid valve in the connecting pipe 9 can control the discharge of wastewater. Finally, the treated water is discharged through the drain pipe outside the effluent tank 4.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field.
