Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a hydrolysis acidification device. Background Technology

[0002] In the field of wastewater treatment, hydrolysis acidification, as a pretreatment step, plays a crucial role in improving the biodegradability of wastewater. However, traditional hydrolysis acidification equipment has revealed numerous problems in actual operation, hindering the improvement of treatment efficiency and effectiveness.

[0003] Existing hydrolysis acidification equipment mostly uses fixed-installation mixing devices, whose mixing range is limited to a specific area and cannot cover the entire treatment tank. This results in numerous mixing dead zones within the tank, uneven mixing of sludge and wastewater, and insufficient contact between organic matter and microorganisms in the wastewater, leading to a slow hydrolysis acidification reaction and low treatment efficiency. While some equipment attempts have tried increasing the number of mixing devices to improve mixing, this not only increases equipment costs and energy consumption but also causes turbulent water flow due to a lack of coordination between the mixing devices, further affecting treatment efficiency. Furthermore, some traditional equipment uses submersible mixers for auxiliary mixing, making maintenance difficult. In case of malfunction, the treatment tank must be emptied before repairs can be carried out, resulting in long downtime and severely impacting the continuity and stability of wastewater treatment.

[0004] Therefore, it is necessary to provide a new hydrolysis acidification device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hydrolysis acidification device.

[0006] This utility model provides a hydrolysis acidification device comprising: a treatment tank, an inlet on one side wall of the treatment tank, a drain on the other side wall of the treatment tank, a top beam fixedly connected to the treatment tank, an adjusting crossbeam located below the top beam, an adjusting seat on the adjusting crossbeam, and a stirring blade assembly installed at the lower end of the adjusting seat; and a high-efficiency stirring mechanism, comprising a main shaft, the lower end of which is fixedly connected to one end of the adjusting crossbeam, a gear fixedly connected to the upper end of the main shaft, a rack on one side of the gear, the rack meshing with the gear, and an electric cylinder on the top beam, the telescopic end of which is fixedly connected to one end of the rack.

[0007] Preferably, the main shaft is rotatably connected to the top beam, the top beam is provided with a mounting seat, and the electric cylinder is fixedly installed in the mounting seat.

[0008] Preferably, the top beam is provided with a limiting transverse strip, and the back side wall of the rack is provided with a limiting groove, and the limiting groove on the rack is slidably connected to the limiting transverse strip.

[0009] Preferably, the adjusting beam has a through slot, the adjusting seat is I-shaped, and the adjusting seat is slidably connected to the through slot.

[0010] Preferably, an internal shaft is rotatably connected in the through slot, and a motor is installed on the outer wall of one end of the adjusting beam, with the output end of the motor fixedly connected to the internal shaft.

[0012] Preferably, the two side walls of the adjusting seat are provided with embedded grooves, and auxiliary rollers are installed and connected in the two embedded grooves. The two auxiliary rollers abut against the two side walls of the through groove.

[0013] Compared with related technologies, the hydrolysis acidification equipment provided by this utility model has the following beneficial effects: 1. This utility model uses the telescopic end of an electric cylinder to push a rack to slide along a limiting transverse bar, causing the gear to drive the main shaft to rotate. The lower end of the main shaft drives the adjusting beam to rotate and adjust the angle, so that the stirring blade assembly installed on the adjusting beam can be adjusted to stir the sludge in a larger space, expand the stirring range, eliminate the stirring dead corners in the treatment tank, effectively improve the mixing uniformity of sludge and sewage, greatly promote the full contact between organic matter and microorganisms in sewage, significantly accelerate the hydrolysis and acidification reaction process, and effectively improve the treatment efficiency and quality of sewage. 2. This utility model drives the internal shaft to rotate through the motor output end. The rotation of the internal shaft causes the adjustment seat to move along the axial direction of the internal shaft in the through slot. During the movement of the adjustment seat, the stirring blade assembly at the lower end moves horizontally, further changing the stirring area. The two movement modes cooperate to form a three-dimensional stirring mode, which effectively accelerates the hydrolysis acidification reaction. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1 to 4 A hydrolysis acidification device includes: a treatment tank 1, with an inlet 2 on one side wall and a drain 21 on the other side wall; a top beam 3 fixedly connected to the treatment tank 1; an adjusting crossbeam 4 located below the top beam 3; an adjusting seat 41 on the adjusting crossbeam 4; and a stirring blade assembly 42 installed at the lower end of the adjusting seat 41; a high-efficiency stirring mechanism including a main shaft 5, the lower end of which is fixedly connected to one end of the adjusting crossbeam 4; a gear 51 fixedly connected to the upper end of the main shaft 5; a rack 52 on one side of the gear 51; the rack 52 meshing with the gear 51; and an electric cylinder 53 on the top beam 3, the telescopic end of which is fixedly connected to one end of the rack 52.

[0018] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the main shaft 5 is rotatably connected to the top beam 3, and the top beam 3 is provided with a mounting seat, in which the electric cylinder 53 is fixedly installed.

[0019] It should be noted that: the extension end of the control electric cylinder 53 pushes the rack 52 to slide along the limit transverse bar 6. Since the rack 52 and the gear 51 mesh with each other, and the gear 51 is fixed on the upper end of the main shaft 5, the gear 51 drives the main shaft 5 to rotate. The lower end of the main shaft 5 drives the adjusting beam 4 to rotate and adjust the angle, so that the stirring blade assembly 42 installed on the adjusting beam 4 can be adjusted to stir the sludge in a larger space.

[0020] refer to Figure 1 and Figure 2 As shown, a limiting horizontal bar 6 is provided on the top beam 3, and a limiting groove is provided on the back side wall of the rack 52. The limiting groove on the rack 52 is slidably connected to the limiting horizontal bar 6.

[0021] It should be noted that the surface of the limiting transverse bar 6 has undergone fine grinding and polishing treatment, which ensures that the rack 52 slides smoothly along the limiting transverse bar 6 while reducing wear and extending the service life of the component. The limiting transverse bar 6 limits the sliding direction of the rack 52.

[0022] refer to Figure 3 and Figure 4As shown, the adjusting beam 4 has a through slot, and the adjusting seat 41 is I-shaped and is slidably connected to the through slot.

[0023] It should be noted that the through slot in the adjusting beam 4 ensures sufficient stability of the adjusting seat 41 during the adjustment process.

[0024] refer to Figure 4 As shown, an internal shaft 7 is rotatably connected through the long slot, and a motor 71 is installed on the outer wall of one end of the adjusting beam 4. The output end of the motor 71 is fixedly connected to the internal shaft 7.

[0025] It should be noted that the output end of the motor 71 drives the built-in shaft 7 to rotate, and the rotation of the built-in shaft 7 causes the adjusting seat 41 to move along the axial direction of the built-in shaft 7 in the through slot. During the movement of the adjusting seat 41, the stirring blade assembly 42 at the lower end moves in the horizontal direction, further changing the stirring area.

[0026] refer to Figure 3 and Figure 4 As shown, the built-in shaft 7 is a threaded rod, and the adjusting seat 41 has a threaded opening, and the adjusting seat 41 is threadedly connected to the built-in shaft 7.

[0027] refer to Figure 4 As shown, both sides of the adjusting seat 41 are provided with embedded grooves, and auxiliary rollers 8 are installed and connected in both embedded grooves. The two auxiliary rollers 8 abut against the two sides of the through groove respectively.

[0028] It should be noted that the auxiliary roller 8 can effectively reduce the friction between the adjusting seat 41 and the side wall of the through groove, and can also play a certain buffering role to avoid direct rigid contact between the adjusting seat 41 and the through groove. The auxiliary roller 8 is installed in the inner groove by a shaft pin. The outer circular surface of the auxiliary roller 8 is ground to ensure that it fits tightly with the side wall of the through groove. It provides stable support and guidance during the movement of the adjusting seat 41, and ensures the straightness and stability of the horizontal movement of the stirring blade assembly 42.

[0029] The working principle of the hydrolysis acidification equipment provided by this utility model is as follows: When sewage flows into the treatment tank 1 through the inlet 2, the hydrolysis acidification process is officially started. The electric cylinder 53 is controlled to work, and its telescopic end pushes the rack 52 to slide along the limiting transverse bar 6. Since the rack 52 and the gear 51 mesh with each other, and the gear 51 is fixed on the upper end of the main shaft 5, the gear 51 drives the main shaft 5 to rotate. The lower end of the main shaft 5 drives the adjusting beam 4 to rotate and adjust a certain angle, so that the stirring blade assembly 42 installed on the adjusting beam 4 can be adjusted to stir the sludge in a larger space, expand the stirring range, and improve the mixing degree of sludge and sewage. At the same time, the control motor 71 starts, and its output end drives the built-in shaft 7 to rotate. The rotation of the built-in shaft 7 causes the adjusting seat 41 to move along the axial direction of the built-in shaft 7 in the through-groove. The auxiliary rollers 8 on the two side walls of the adjusting seat 41 abut against the two side walls of the through-groove, which can reduce the friction when the adjusting seat 41 moves and ensure that the adjusting seat 41 slides smoothly. During the movement of the adjusting seat 41, the stirring blade assembly 42 at the lower end moves in the horizontal direction, further changing the stirring area and achieving a larger range of stirring. This allows the sludge at the bottom of the treatment tank 1 to be fully and evenly stirred, promoting full contact between organic matter and microorganisms in the sewage and accelerating the hydrolysis acidification reaction. After the reaction is completed, the treated sewage is discharged from the treatment tank 1 through the drain outlet 21, completing the entire hydrolysis acidification treatment process.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
