Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a multi-stage high-efficiency sewage treatment equipment. Background Art

[0002] A large amount of large particle impurities, insoluble suspended impurities, peculiar smell, metal ions and organic matters are contained in sewage. In order to make the sewage meet the water quality requirements for discharging into a certain water body or being reused, a multi-stage high-efficiency sewage treatment equipment is needed at this time.

[0003] In order to improve the sewage treatment efficiency, the sewage is generally stirred before solid-liquid separation to ensure that the suspended substances and solid substances in the sewage are evenly mixed into the water, making the subsequent physical filtration or solid-liquid separation more effective. However, the stirring speed of the existing equipment is fixed and cannot be adaptively adjusted according to the sewage discharge volume. When the water flow is small, the stirring component does not need the highest speed to achieve the treatment effect, which is likely to cause over-operation and energy waste. Summary of the Utility Model

[0004] Aiming at the above-mentioned shortcomings of the prior art, the utility model provides a multi-stage high-efficiency sewage treatment equipment, which can effectively solve the problem that the rotation speed of the stirring component cannot be adaptively adjusted according to the sewage discharge volume in the prior art.

[0005] To achieve the above object, the utility model is realized through the following technical solutions:

[0006] The utility model provides a multi-stage high-efficiency sewage treatment equipment, including a box body and a partition board. The interior of the box body is divided into a first treatment chamber, a second treatment chamber and a third treatment chamber by the partition board. A water inlet pipe is communicated with the inner top wall of the first treatment chamber, and a water outlet pipe is communicated with one side inner wall of the third treatment chamber. The other ends of the water inlet pipe and the water outlet pipe both penetrate through the box body. A stirring component and a speed change component are arranged inside the first treatment chamber;

[0007] The speed change component includes a fixed block, a sliding resistance rod and a connecting rod. Irregular cavities are provided inside the fixed block at the corresponding positions of the sliding resistance rod and the connecting rod. The sliding resistance rod is fixedly installed inside the cavity. The connecting rod is slidably connected with the cavity. A sliding piece is in sliding contact with the outer wall of the sliding resistance rod, and the other end of the sliding piece is fixedly installed on the outer side of the connecting rod. A baffle is fixedly installed at the top end of the connecting rod, and a spring is fixedly installed between the bottom of the connecting rod and the opposite side of the cavity.

[0008] According to the above-mentioned multi-stage high-efficiency sewage treatment equipment, the stirring assembly includes a motor fixedly installed at the top of the box body and directly above the first treatment chamber. The output end of the motor penetrates through the first treatment chamber and is fixedly installed with a stirring shaft. A plurality of stirring rods are fixedly installed on the outer side of the stirring shaft. The sliding resistance rod, the sliding piece and the motor are electrically connected to form an adjustment circuit. During the process that the sliding piece slides downward along the sliding resistance rod, the resistance in the adjustment circuit decreases.

[0009] According to the above-mentioned multi-stage high-efficiency sewage treatment equipment, a plurality of installation grooves are vertically and equidistantly opened on the outer side of the box body at the corresponding position of the second treatment chamber, and a filtering assembly is slidably connected inside the installation grooves.

[0010] According to the above-mentioned multi-stage high-efficiency sewage treatment equipment, the filtering assembly includes a collection box and a filter screen. A limiting plate is fixedly installed at one end of the filter screen close to the collection box, and a limiting groove for sliding connection therewith is opened at the corresponding position inside the collection box and at the position of the limiting plate.

[0011] According to the above-mentioned multi-stage high-efficiency sewage treatment equipment, two sewage discharge pipes are symmetrically communicated at the bottom of the box body, and control valves are arranged on the outer sides of the two sewage discharge pipes.

[0012] According to the above-mentioned multi-stage high-efficiency sewage treatment equipment, the opposite side of the baffle plate is slidably connected to the first treatment chamber, and an inclined surface is arranged at the top of the baffle plate.

[0013] The technical solution provided by the present utility model has the following beneficial effects compared with the known prior art:

[0014] By setting a speed change assembly in the present utility model, when the sewage discharge volume is large, the impact force on the baffle plate is stronger, causing the connecting rod to drive the sliding piece to move downward. At this time, the sliding piece is closer to the coil length inside the sliding resistance rod, resulting in a smaller resistance in the adjustment circuit and a larger voltage applied to the stirring assembly. Therefore, the rotation speed of the stirring assembly increases. On the contrary, when the sewage discharge volume is small, the rotation speed of the stirring assembly slows down. It can adjust the rotation speed of the stirring assembly to an appropriate level according to actual needs, avoiding over-operation and energy waste while meeting the requirements.

Specific embodiments

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model will be further described below with reference to the embodiments.

[0023] Embodiment: Refer to Figures 1 to 4 , a multi-stage high-efficiency sewage treatment device, including a box body 1 and a partition board. The interior of the box body 1 is divided into a first treatment chamber 2, a second treatment chamber 3 and a third treatment chamber 4 by the partition board. The inner top wall of the first treatment chamber 2 is communicated with a water inlet pipe 21, and one side inner wall of the third treatment chamber 4 is communicated with a water outlet pipe 41. The other ends of the water inlet pipe 21 and the water outlet pipe 41 both penetrate the box body 1. A stirring component and a speed change component are arranged inside the first treatment chamber 2;

[0024] The speed-changing component includes a fixed block 5, a sliding resistance rod 52, and a connecting rod 53. Inside the fixed block 5, irregular cavities 51 are provided at the corresponding positions of the sliding resistance rod 52 and the connecting rod 53. The sliding resistance rod 52 is fixedly installed inside the cavity 51, and the connecting rod 53 is slidably connected to the cavity 51. A sliding contact piece 54 is in sliding contact with the outer wall of the sliding resistance rod 52, and the other end of the sliding contact piece 54 is fixedly installed on the outside of the connecting rod 53. A baffle 55 is fixedly installed at the top of the connecting rod 53, and a spring 56 is fixedly installed at the bottom of the connecting rod 53 on the opposite side of the cavity 51. Sewage enters the first treatment chamber 2 through the water inlet pipe 21, and the impact force of the water flow directly acts on the baffle 55. When the water flow rate is larger, the impact force is greater, causing the baffle 55 to drive the connecting rod 53 at the bottom to move downward. The connecting rod 53 drives the sliding contact piece 54 on one side to move simultaneously. At this time, the sliding contact piece 54 is closer to the length of the coil inside the sliding resistance rod 52, resulting in a smaller resistance in the adjustment circuit and a larger voltage applied to the stirring component. Therefore, the rotation speed of the stirring component increases. On the contrary, when the water flow rate is smaller, the impact force is smaller, and the elastic force of the spring 56 pushes the connecting rod 53 upward, causing the sliding contact piece 54 to be farther from the length of the coil inside the sliding resistance rod 52, resulting in a larger resistance in the adjustment circuit and a smaller voltage applied to the stirring component, making the rotation frequency of the stirring component slower. According to actual needs, the rotation speed of the stirring component can be adjusted to an appropriate level to meet the current treatment requirements, which can avoid over-operation and energy waste.

[0025] The stirring component includes a motor 6 fixedly installed on the top of the box body 1 and directly above the first treatment chamber 2. The output end of the motor 6 penetrates through the first treatment chamber 2 and is fixedly installed with a stirring shaft 61. A plurality of stirring rods 62 are fixedly installed on the outside of the stirring shaft 61. The sliding resistance rod 52, the sliding contact piece 54, and the motor 6 are electrically connected to form an adjustment circuit. During the process of the sliding contact piece 54 sliding downward along the sliding resistance rod 52, the resistance in the adjustment circuit decreases, starting the motor 6 to drive the stirring shaft 61 to rotate. Using the plurality of stirring rods 62 on the outside of the stirring shaft 61 to stir the sewage, mixing the suspended substances and solid substances in the sewage into the water, which helps to reduce the particle size of the particulate matter in the wastewater and disperse the sludge, making the subsequent treatment steps more effective.

[0026] A plurality of installation slots 31 are vertically and equidistantly provided on the outside of the box body 1 at the corresponding position of the second treatment chamber 3. A filtering component is slidably connected inside the installation slots 31, and the sewage is filtered through the plurality of filtering components to improve the treatment effect of the sewage.

[0027] The filtering component includes a collection box 7 and a filter screen 71. A limiting plate 72 is fixedly installed at one end of the filter screen 71 close to the collection box 7. Inside the collection box 7, a limiting groove 73 is provided at the corresponding position of the limiting plate 72 and is slidably connected thereto. By setting the detachable filter screen 71, it is convenient to replace the filter screen 71 and improve the use effect of the equipment.

[0028] Two sewage pipes 8 are symmetrically connected to the bottom of the box body 1. Control valves are arranged on the outer sides of the two sewage pipes 8. The two sewage pipes 8 are respectively used for discharging the residual water inside the first treatment chamber 2, the second treatment chamber 3 and the third treatment chamber 4, so as to improve the use effect of the equipment.

[0029] The baffle 55 is slidably connected to the opposite side of the first treatment chamber 2. An inclined surface is arranged at the top of the baffle 55, which further improves the stability of the movement of the baffle 55 and can prevent sewage from accumulating on the top of the baffle 55.

[0030] The working principle of the present utility model is as follows: When in use, sewage enters the first treatment chamber 2 through the water inlet pipe 21, and then the motor 6 is started. The output end drives the stirring shaft 61 to rotate, and the stirring shaft 61 drives a plurality of stirring rods 62 on the outside to move simultaneously, so as to stir the sewage inside the first treatment chamber 2, mix the suspended substances and solid substances in the sewage into the water, which helps to reduce the particle size of the particulate matter in the wastewater and disperse the sludge, making the subsequent treatment steps more effective. At the same time, the impact force of the water flow directly acts on the baffle 55. When the water flow rate is larger, the impact force is greater, causing the baffle 55 to drive the connecting rod 53 at the bottom to move downward, and the connecting rod 53 drives the sliding piece 54 on one side to move simultaneously. At this time, the sliding piece 54 is closer to the length of the coil in the sliding rheostat rod 52, resulting in a smaller resistance of the adjustment circuit and a larger voltage applied to the motor 6. Therefore, the rotation speed of the motor 6 increases. On the contrary, when the water flow rate is smaller, the impact force is smaller, and the elastic force of the spring 56 pushes the connecting rod 53 upward, making the sliding piece 54 farther away from the length of the coil in the sliding rheostat rod 52, resulting in a larger resistance of the adjustment circuit and a smaller voltage applied to the motor 6, making the rotation frequency of the motor 6 slower. The rotation speed of the motor 6 can be adjusted to an appropriate level according to actual needs to meet the current treatment requirements, which can avoid over-operation and energy waste.

[0031] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the present utility model in each embodiment.
