Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater anaerobic biogas impurity separation device. Background Technology

[0002] In the field of wastewater treatment, the mixing of chemicals is a core process, and its efficiency and accuracy directly affect the treatment effect and operating costs. At present, traditional wastewater mixing equipment has many technical bottlenecks: On the one hand, most equipment uses concentric mixing blades, which easily form symmetrical vortices centered on the axis during the mixing process, resulting in mixing dead corners at the edge and bottom of the container. Especially when treating low-viscosity wastewater, a large amount of energy is consumed in ineffective circumferential rotation, resulting in low mixing efficiency.

[0003] On the other hand, the dosing process relies heavily on manual, timed operations, which not only incurs high labor costs but also suffers from inaccurate dosing times and large dosage fluctuations, making it difficult to meet the demands of automation and refined treatment. Furthermore, the fixed-height agitator blades cannot be flexibly adjusted according to changes in wastewater level or material stratification characteristics. For wastewater with high levels or large density differences, the mixing efficiency between the upper and lower layers is insufficient, affecting the full reaction between the reagents and the wastewater.

[0004] Therefore, it is necessary to develop a new type of mixing equipment that integrates timed dispensing, efficient mixing, and dynamic adjustment functions to solve the problems of high energy consumption, low efficiency, and poor automation in the existing technology for wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a wastewater anaerobic biogas impurity separation device that can solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater anaerobic biogas impurity separation device, comprising a stirring device, a fan blade lifting module, a drug outlet pipe, and a stirring tank, wherein the stirring device is located directly above the stirring tank;

[0007] The front of the mixing tank is fixedly connected to the inlet pipe and the outlet pipe. A filter screen is installed inside the mixing tank, and a support base is fixedly connected to the bottom.

[0008] The mixing tank is equipped with a first lifting column and a second lifting column on both sides. The lifting module is located on the opposite side of the first lifting column and the second lifting column, and the mixing device is located on the two lifting modules.

[0009] The mixing device consists of a reagent tank, a motor, a coupling, a reducer, a first mixing blade, a second mixing blade, a reagent outlet pipe, and a mixing device mounting plate.

[0010] Preferably, the stirring device mounting plate is fixedly connected to two lifting modules, the medicine tank is fixedly connected to the stirring device mounting plate, and the motor and reducer are connected by a coupling.

[0011] The first and second stirring blades are rotatably connected to the stirring device mounting plate.

[0012] Preferably, the bottom of the dispensing tube has a dispensing hole.

[0013] Preferably, the dispensing pipe is connected to the mixing tank for dispensing the medicine, and a sealing rod is slidably connected to the bottom of the dispensing pipe;

[0014] Another gear is meshed with the gear on the second stirring blade, and the sealing rod is eccentrically connected to the other gear meshed with by the second stirring blade.

[0015] The sealing rod consists of two rectangular rods that are rotatably connected to each other.

[0016] Preferably, the first stirring fan blade is fixedly connected to the output end of the reducer.

[0017] Preferably, gears are fixedly connected to both the first and second stirring blades, and the gears on the first and second stirring blades are meshed together.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) The wastewater anaerobic biogas impurity separation device replaces manual operation by using a gear reciprocating timed dosing device, reducing manpower input, avoiding dosing errors caused by human factors, ensuring the stability and accuracy of dosing, and improving the reliability of wastewater treatment effect.

[0020] (2) The wastewater anaerobic biogas impurity separation device adopts an eccentrically installed stirring fan blade, which breaks the symmetry of fluid movement and causes the wastewater to generate strong radial and axial diversion while flowing in the circumferential direction, effectively suppressing the formation of vortex. Compared with traditional concentric stirring, under the same power, eccentric stirring can use more energy for the convection and shearing of wastewater, quickly eliminate stirring dead corners, and is especially suitable for the efficient mixing of low viscosity wastewater, greatly shortening the mixing time.

[0021] (3) The anaerobic biogas impurity separation device for wastewater has a stirring fan blade lifting device that can realize the vertical reciprocating motion of the fan blade, forcibly pushing the upper layer of wastewater downward and the lower layer of wastewater upward, forming a piston-type axial circulation, which significantly enhances the material exchange efficiency between the upper and lower layers of wastewater. For high-level wastewater or situations where there is density stratification, this design can effectively eliminate the concentration gradient between the upper and lower layers, ensuring that the reagent and wastewater are fully and evenly mixed.

[0031] Please see Figure 1-3 This utility model provides a technical solution: a wastewater anaerobic biogas impurity separation device, including a stirring device 8, a fan blade lifting module 3, a drug outlet pipe 807, and a stirring tank 7, with the stirring device 8 located directly above the stirring tank 7;

[0032] The mixing tank 7 is fixedly connected to the inlet pipe 4 and the outlet pipe 5. The filter screen 701 is installed inside the mixing tank 7, and the bottom is fixedly connected to the support base 6.

[0033] Wastewater flows into the mixing tank 7 through the inlet pipe 4. The filter screen 701 first intercepts large particulate impurities in the wastewater to prevent them from affecting the subsequent mixing and treatment effect. The wastewater is stored in the mixing tank 7, which lays the foundation for the treatment process.

[0034] The mixing tank 7 is provided with a first lifting column 1 and a second lifting column 2 on both sides, and the lifting module 3 is provided on the opposite side of the first lifting column 1 and the second lifting column 2.

[0035] The stirring device 8 is installed on the two lifting modules 3;

[0036] The lifting module 3 can be used to control the stirring device 8 to move up and down.

[0037] Among them, the lifting module 3 is a known technical means, so it will not be described in detail.

[0038] The stirring device 8 consists of a reagent tank 801, a motor 802, a coupling 803, a reducer 804, a first stirring blade 805, a second stirring blade 806, a discharging pipe 807, and a stirring device mounting plate 808.

[0039] The mixing device mounting plate 808 is fixedly connected to the two lifting modules 3, the medicine tank 801 is fixedly connected to the mixing device mounting plate 808, and the motor 802 and the reducer 804 are connected by a coupling 803.

[0040] The first stirring blade 805 and the second stirring blade 806 are rotatably connected to the stirring device mounting plate 808, and the first stirring blade 805 is fixedly connected to the output end of the reducer 804.

[0041] Gears 9 are fixedly connected to both the first stirring blade 805 and the second stirring blade 806, and the gears 9 on the first stirring blade 805 and the second stirring blade 806 are meshed together.

[0042] The dispensing pipe 807 is connected to the mixing tank 801, and a sealing rod is slidably connected to the bottom of the dispensing pipe 807.

[0043] Another gear 9 is meshed with the gear 9 on the second stirring blade 806, and the sealing rod is eccentrically connected to the other gear 9 meshed with the second stirring blade 806.

[0044] The sealing rod consists of two rectangular rods that are rotatably connected to each other;

[0045] A dispensing hole is provided at the bottom of the dispensing tube 807;

[0046] Working principle: Wastewater flows into the mixing tank 7 through the inlet pipe 4. The filter screen 701 first intercepts large particulate impurities in the wastewater to avoid affecting the subsequent mixing and treatment effect. The wastewater is stored in the mixing tank 7, which lays the foundation for the treatment process.

[0047] After the equipment is started, the motor 802 drives the reducer 804 through the coupling 803. The reducer 804 reduces the power of the motor 802 and increases the torque, and then transmits the power to the first stirring blade 805 and the second stirring blade 806. The gear 9 drives the blades to rotate around the trajectory that deviates from the central axis of the mixing tank 7. The eccentric design breaks the symmetry of the fluid motion, so that the sewage generates strong radial and axial diversion while moving in the circumferential direction, effectively suppressing the formation of vortex and enhancing the mixing efficiency of each part of the sewage.

[0048] At the same time, the lifting modules 3 on both sides of the mixing device mounting plate 808 start to work. According to the preset program or real-time monitoring parameters such as sewage level and mixing status, the lifting modules 3 drive the mixing device 8 to move up and down along the first lifting column 1 and the second lifting column 2, driving the first mixing fan blade 805 and the second mixing fan blade 806 to perform vertical reciprocating motion. When the first mixing fan blade 805 and the second mixing fan blade 806 move upward, they lift the lower layer of sewage and when they move downward, they press down the upper layer of sewage, forming a piston-type axial circulation, which further enhances the convection of the upper and lower layers of sewage, ensuring that the sewage can be fully mixed in all areas of the mixing tank 7. It is especially suitable for treating sewage with density stratification or high liquid level.

[0049] The working process of the timed chemical dosing device is as follows: The chemical dosing tank 801, which is fixed on the stirring device mounting plate 808, stores the purification agent. The bottom dispensing pipe 807 is powered by the gear 9. When the gear 9 rotates, it drives the dispensing pipe 807 to operate. According to the preset time interval and dosage requirements, the purification agent in the chemical dosing tank 801 is released into the sewage in the stirring tank 7 at regular intervals and in quantitative quantities. After the agent is added, the first stirring fan blade 805, the second stirring fan blade 806 and the fan blade lifting module 3 work together to quickly promote the diffusion of the agent in the sewage, ensuring that the agent and the sewage are in full contact and react, thereby improving the sewage treatment effect.

[0050] The treated wastewater is discharged from the mixing tank 7 through the outlet pipe 5. The entire treatment process is automated, realizing the timed and precise dosing of chemicals and efficient mixing of wastewater during the wastewater purification process, reducing manual intervention and improving wastewater treatment efficiency and quality.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
