Description

Technical Field

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

[0002] Wastewater treatment processes include primary treatment, secondary treatment, and tertiary treatment. Primary treatment is a mechanical or pretreatment stage, mainly removing suspended solid pollutants from wastewater. Secondary treatment is a biological treatment stage, mainly removing colloidal and dissolved organic pollutants (BOD, COD) from wastewater. Tertiary treatment is an advanced treatment stage, further removing recalcitrant organic matter, soluble inorganic substances such as nitrogen and phosphorus, as well as suspended solids, so that the effluent meets higher water quality standards.

[0003] The secondary treatment process includes an equalization tank, a biological treatment tank, and a biological treatment tank. First, the equalization tank regulates the quantity and quality of the wastewater to ensure the normal operation of subsequent treatment equipment. Then, in the biological treatment tank, technologies such as activated sludge and biofilm processes are used to degrade organic matter through microorganisms. Subsequently, activated sludge and purified water are separated in the biological treatment tank; part of the sludge is returned to the biological treatment tank, and part enters the sludge treatment system. In the biological treatment tank, to activate the growth and metabolic processes of microorganisms and improve treatment efficiency, growth rate regulators, nutrients (such as nitrogen and phosphorus), and trace elements are typically added.

[0004] Currently, many wastewater treatment processes opt to add microorganisms and chemicals directly to the biological treatment tank. However, due to the large volume of the biological treatment tank, direct addition makes it difficult to ensure that the microorganisms and chemicals can be rapidly and evenly distributed throughout the entire tank. This not only reduces treatment efficiency but may also lead to excessively high or low local concentrations, affecting the overall treatment effect.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a new type of sewage treatment equipment to overcome the shortcomings in current practical applications. Utility Model Content

[0006] The purpose of this utility model embodiment is to provide a new type of sewage treatment equipment, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel wastewater treatment device includes a base frame, a mixing chamber, and a top cover. The mixing chamber is fixedly installed on the base frame and has an inlet and an outlet. The top cover is detachably connected to the mixing chamber, and a hollow tube is rotatably connected to the top cover. The lower end of the hollow tube is located inside the mixing chamber. The hollow tube has multiple evenly distributed injection ports for injecting microorganisms and chemicals into the mixing chamber. A stirring assembly is fitted onto the outer wall of the hollow tube, and a thrust assembly is also fitted onto the upper outer wall of the hollow tube to drive the hollow tube to rotate. A transition bottle is fixedly connected to the top of the hollow tube, and the transition bottle has a feeding pipe and a pressurizing pipe.

[0009] In a further technical solution, the water inlet is positioned at a lower height than the water outlet.

[0010] In a further technical solution, a rotary joint is connected to the pressurization pipe, an air pump is fixedly connected to the top cover, an air supply pipe is fixedly connected to the air outlet of the air pump, and a rotary joint is connected to the other end of the air supply pipe.

[0011] In a further technical solution, the pressure tube and the cavity tube are collinear.

[0012] In a further technical solution, the thrust assembly includes a motor, a first bevel gear, and a second bevel gear; the second bevel gear is fixedly sleeved on the outer wall of the cavity tube, and a motor is fixedly connected to the upper end of the top cover. The drive end of the motor is fixedly connected to the first bevel gear, and the first bevel gear meshes with the cavity tube.

[0013] A further technical solution includes a collar, a first stirrer, a fixed shaft, a sleeve, and a second stirring plate; two collars are fixedly sleeved on the outer wall of the cavity tube, and multiple first stirrers are fixedly connected to each collar and evenly distributed around the axis of the cavity tube, with the first stirrers on the two collars corresponding one-to-one, and a fixed shaft is fixedly connected between the corresponding first stirrers. A sleeve is rotatably sleeved on the outer wall of the fixed shaft, and multiple second stirring plates are fixedly connected to the outer wall of the sleeve and evenly distributed around the fixed shaft.

[0014] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0015] 1. Microorganisms and agents are added to the transition bottle through the feeding pipe, and then injected into the sewage in the mixing chamber through the injection port on the hollow tube. After that, the sewage is stirred by the stirring component, so that the sewage, microorganisms and agents are quickly and evenly mixed.

[0016] 2. Pressurize the transition bottle through an air pump and air delivery pipe. The air delivery pipe and pressurization pipe can rotate relative to each other through a rotary joint, thereby preventing microorganisms and agents from clogging the cavity tube. By controlling the amount of air pressure applied to the transition bottle by the air pump, the speed at which microorganisms and agents are injected into the mixing chamber through the inlet can be controlled.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figure 1-3As shown in the figure, this utility model embodiment provides a novel wastewater treatment device. This novel wastewater treatment device is fixedly installed between an equalization tank and a biological treatment tank, and includes a base frame 1, a mixing chamber 2, and a top cover 5. The mixing chamber 2 is fixedly installed on the base frame 1, and the mixing chamber 2 has an inlet 4 and an outlet 3. The top cover 5 is detachably connected to the mixing chamber 2, and a hollow tube 7 is rotatably connected to the top cover 5. The lower end of the hollow tube 7 is located inside the mixing chamber 2, and the hollow tube 7 has multiple evenly distributed injection ports 14. Microorganisms and agents are injected into the mixing chamber 2 through the injection port 14. A stirring assembly 15 is sleeved on the outer wall of the hollow tube 7. The stirring assembly 15 is used to stir the sewage, so that the sewage, microorganisms and agents are quickly and evenly mixed. A thrust assembly 6 is also connected to the upper outer wall of the hollow tube 7. The thrust assembly 6 is used to drive the hollow tube 7 to rotate. A transition bottle 8 is fixedly connected to the top of the hollow tube 7. The transition bottle 8 is provided with a feeding pipe 9 and a pressurizing pipe 10. The feeding pipe 9 is used to add microorganisms and agents.

[0025] Understandably, this new type of sewage treatment equipment is fixedly installed between the equalization tank and the biological treatment tank. The inlet 4 is connected to the equalization tank through a pipe, and the outlet 3 is connected to the biological treatment tank through another pipe.

[0026] Furthermore, the inlet 4 is positioned at a lower height than the outlet 3, which facilitates increasing the residence time of wastewater in the mixing chamber 2, thereby enhancing the mixing effect of wastewater with microorganisms and agents.

[0027] Furthermore, a rotary joint 13 is connected to the pressurizing pipe 10, and an air pump 12 is fixedly connected to the top cover 5. An air supply pipe 11 is fixedly connected to the air outlet end of the air pump 12, and the other end of the air supply pipe 11 is connected to the rotary joint 13. The rotary joint 13 allows the air supply pipe 11 and the pressurizing pipe 10 to rotate relative to each other.

[0028] Furthermore, the pressure tube 10 and the cavity tube 7 are collinear.

[0029] Specifically, wastewater flows into the mixing chamber 2 from the inlet 4. Microorganisms and agents are added to the transition bottle 8 through the feeding pipe 9. Then, the wastewater is injected into the mixing chamber 2 through the injection port 14 on the hollow pipe 7. After that, the wastewater is stirred by the stirring component 15, so that the wastewater, microorganisms and agents are quickly and evenly mixed. Then, it flows out from the outlet 3. The transition bottle 8 is pressurized by the air pump 12 and the air supply pipe 11. The air supply pipe 11 and the pressurizing pipe 10 can rotate relative to each other through the rotary joint 13, so as to prevent the microorganisms and agents from clogging in the hollow pipe 7. In addition, by controlling the amount of air pressure applied to the transition bottle 8 by the air pump 12, the speed at which the microorganisms and agents are injected into the mixing chamber 2 through the injection port 14 can be controlled.

[0030] like Figure 1 and Figure 2 As shown, the thrust assembly 6 includes a motor 61, a first bevel gear 62, and a second bevel gear 63; the second bevel gear 63 is fixedly sleeved on the outer wall of the cavity tube 7, and the motor 61 is fixedly connected to the upper end of the top cover 5. The driving end of the motor 61 is fixedly connected to the first bevel gear 62, and the first bevel gear 62 meshes with the cavity tube 7.

[0031] Specifically, the motor 61 drives the first bevel gear 62 to rotate, and then the first bevel gear 62 drives the cavity tube 7 to rotate through the second bevel gear 63.

[0032] like Figure 2 and Figure 3 As shown, the stirring assembly 15 includes a collar 151, a first stirrer 152, a fixed shaft 153, a sleeve 154, a second stirring plate 155, a gear ring 156, and a mating gear 157. Two collars 151 are fixedly sleeved on the outer wall of the cavity tube 7. Multiple first stirrers 152 are fixedly connected to each collar 151 and are evenly distributed around the axis of the cavity tube 7. The first stirrers 152 on the two collars 151 correspond one-to-one. A fixed shaft 153 is rotatably connected between the corresponding first stirrers 152. A sleeve 154 is fixedly sleeved on the outer wall of the fixed shaft 153. Multiple second stirring plates 155 are fixedly connected to the outer wall of the sleeve 154 and are evenly distributed around the fixed shaft 153. A mating gear 157 is fixedly connected to the upper end of the fixed shaft 153. A mating gear 157 is fixedly connected to the inner wall of the mixing chamber 2, and the mating gear 157 meshes with the gear ring 156.

[0033] Specifically, the hollow tube 7 drives the collar 151 to rotate, and then the collar 151 drives the first stirrer 152 to rotate axially around the hollow tube 7. The first stirrer 152 synchronously drives the fixed shaft 153 to move. Then the fixed shaft 153 drives the sleeve 154 to rotate axially around the hollow tube 7. During this process, the toothed ring 156 drives the mating gear 157 to rotate in the opposite direction. Then the mating gear 157 drives the fixed shaft 153 to rotate. Then the fixed shaft 153 drives the second stirring plate 155 to rotate around the axis of the fixed shaft 153 through the sleeve 154, thereby making the microorganisms and agents quickly and evenly mixed with the sewage.

[0034] The working principle of this utility model is as follows: Wastewater flows from the previous process into the mixing chamber 2 through the inlet 4. Microorganisms and agents are added into the transition bottle 8 through the feeding pipe 9. Then, the air pump 12 and motor 61 are started. The air pump 12 pressurizes the transition bottle 8 through the air supply pipe 11, and then injects the wastewater into the mixing chamber 2 through the injection port 14 on the cavity pipe 7. The motor 61 synchronously drives the first bevel gear 62 to rotate. Then, the first bevel gear 62 drives the cavity pipe 7 to rotate through the second bevel gear 63. The cavity pipe 7 drives the collar 151 to rotate, and then the collar 151 drives... The first agitator 152 rotates axially around the cavity tube 7. Simultaneously, the first agitator 152 drives the fixed shaft 153 to rotate around the cavity tube 7. Then, the fixed shaft 153 drives the sleeve 154 to rotate axially around the cavity tube 7. During this process, the gear ring 156 drives the mating gear 157 to rotate in the opposite direction. Then, the mating gear 157 drives the fixed shaft 153 to rotate. Then, the fixed shaft 153 drives the second agitator 155 to rotate around the axis of the fixed shaft 153 through the sleeve 154. This allows the microorganisms and agents to be quickly and evenly mixed with the sewage, and then flow into the next process from the outlet 3.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
