Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to a construction wastewater mixer with rapid material feeding. Background Technology

[0002] Construction wastewater is characterized by high levels of suspended solids and high concentrations of impurities. These substances are dense and easily settle, and long-term stagnation can lead to the formation of a hard, compacted layer. This not only results in low efficiency for manual cleaning but also easily clogs subsequent equipment. Traditional treatment methods that rely solely on sedimentation tanks cannot address this issue. Furthermore, with increasingly stringent environmental regulations, construction wastewater must be treated to meet standards before it can be discharged or reused. Mixers can break the tendency of particle settling through mechanical agitation, providing a pre-treatment guarantee for subsequent wastewater treatment and ensuring both efficiency and compliance rates. Therefore, the emergence of construction wastewater mixers is an inevitable result of the combined effects of the upgrading demand for wastewater treatment in the construction industry and increasingly stringent environmental regulations.

[0003] The main structural components of a construction wastewater mixer include power drive components such as a motor and reducer, which provide stable power for mixing and meet the low-speed, high-torque requirements of wastewater mixing; mixing execution components such as a mixing shaft and mixing blades, with blades being mostly paddle-type or spiral-type wear-resistant types that directly contact the wastewater and disperse suspended solids to prevent caking; support and fixing components such as a frame, base, or suspension device to prevent wastewater from seeping into the power or transmission components and causing corrosion or damage, making it suitable for the high-impurity and corrosive environment of construction wastewater; and auxiliary control components such as start / stop switches and overload protection devices. Some high-end models include speed adjustment functions to ensure safe operation of the equipment and adapt to the mixing needs of different wastewater concentrations.

[0004] Existing construction wastewater mixers lack the ability to quickly feed chemicals. Impurities such as silt and cement residue in construction wastewater need to be rapidly mixed and reacted with chemicals to achieve efficient solid-liquid separation. If the chemical feeding is slow, the chemicals and wastewater cannot be mixed in a timely and uniform manner. Some wastewater enters the mixing stage before the chemicals have fully acted, which not only reduces the flocculation and sedimentation effect of impurities but also makes it difficult for the treated wastewater to meet discharge standards, increasing environmental compliance risks. Therefore, a construction wastewater mixer with rapid feeding is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 and Figure 4 This utility model provides an embodiment of a rapid-feeding construction wastewater mixer, comprising a mixing tank 1. The mixing tank 1 serves as the core mixing space for wastewater and treatment agents, providing a closed environment for subsequent mixing actions to prevent wastewater splashing or odor leakage during mixing. A cylinder 4 is rotatably connected to the top of the mixing tank 1, and a switching mechanism 5 is fixedly connected to the output end of the cylinder 4. The fixed connection between the output end of the cylinder 4 and the switching mechanism 5 allows the pneumatic power of the cylinder 4 to be directly transmitted to the switching mechanism 5, reducing power loss and ensuring that the switching mechanism 5 can quickly respond to the action of the cylinder 4, thereby realizing the rapid opening and closing of the feeding hole.

[0034] The switching mechanism 5 includes a bearing 51. As a transmission auxiliary component of the switching mechanism 5, the bearing 51 can reduce the frictional resistance between the output end of the cylinder 4 and the handle 52, making the handle 52 rotate more smoothly, reducing component wear, and ensuring the long-term stable operation of the switching mechanism 5. One end of the bearing 51 is rotatably connected to the output end of the cylinder 4. The rotatable connection between the output end of the bearing 51 and the output end of the cylinder 4 allows the output end of the cylinder 4 to adjust its posture with the change of the angle of the handle 52 when pushing the bearing 51, avoiding jamming caused by the conflict of the action angle between the cylinder 4 and the handle 52, and ensuring continuous power transmission. The end of the bearing 51 away from the cylinder 4 is fixedly connected to the handle 52. The fixed connection between the end of the bearing 51 away from the cylinder 4 and the handle 52 can stably transmit the power received by the bearing 51 to the handle 52, so that the handle 52 can rotate synchronously with the action of the bearing 51, providing reliable power for driving the movement of the base block 53.

[0035] A base block 53 is fixedly connected to the end of the throttle 52 away from the bearing 51. The fixed connection between the end of the throttle 52 away from the bearing 51 and the base block 53 ensures that the rotational force of the throttle 52 can directly act on the base block 53, causing the base block 53 to rotate synchronously with the throttle 52, thereby driving the top sliding block 54 to slide. This provides a key action for opening and closing the feeding hole. Multiple sliding blocks 54 are slidably connected to the top of the base block 53. The sliding connection between the top of the base block 53 and the multiple sliding blocks 54 allows the sliding blocks 54 to move in a specific direction under the action of the base block 53. By staggering or splicing the multiple sliding blocks 54, the feeding hole can be opened or closed, ensuring that the material can smoothly enter the mixing tank 1. A groove is opened on the top of the base block 53, and a locking block is slidably connected to the bottom of the sliding block 54 in the groove. The sliding cooperation between the groove on the top of the base block 53 and the locking block at the bottom of the sliding block 54 provides a clear guide for the sliding block 54, restricts its displacement direction, prevents the sliding block 54 from deviating or falling off, and ensures the precise opening and closing action of the feeding hole.

[0036] Multiple sliding blocks 54 are slidably connected to a top block 55. The slidable connection between the top of the multiple sliding blocks 54 and the top block 55 allows the top block 55 to limit the top of the sliding blocks 54. Together with the guide of the bottom block 53, this forms a two-way constraint on the sliding blocks 54, improving the stability of the sliding blocks 54 during sliding. The outer side of the bottom block 53 is slidably connected to a limit block 56. The slidable connection between the outer side of the bottom block 53 and the limit block 56 can limit the rotation range of the bottom block 53, preventing the bottom block 53 from over-rotating due to excessive driving force of the handle 52, and preventing the sliding block 54 from sliding beyond its travel, which could cause the feed hole switch to malfunction. The outer side of the limit block 56 has a groove, and the handle 52 is slidably connected in the groove. The groove on the outer side of the limit block 56 and the sliding cooperation of the handle 52 provide a fixed sliding trajectory for the handle 52, limiting its rotation range, thereby controlling the rotation angle of the bottom block 53 and ensuring that the sliding amplitude of the sliding block 54 matches the size of the feed hole.

[0037] The top of the switching mechanism 5 is fixedly connected to the storage tank 2. The fixed connection between the top of the switching mechanism 5 and the storage tank 2 allows the material in the storage tank 2 to directly correspond to the feeding hole. When the switching mechanism 5 opens the feeding hole, the material can quickly fall into the mixing tank 1 without the need for an additional conveying path, thus improving feeding efficiency. The outer side of the top block 55 is slidably connected to the inner side of the limiting block 56. The slidable connection between the outer side of the top block 55 and the inner side of the limiting block 56 allows the limiting block 56 to fix the position of the top block 55, preventing the top block 55 from shifting when the sliding block 54 slides. This ensures that the top block 55 stably provides top guidance for the sliding block 54, ensuring the overall stability of the switching mechanism 5. The top block 55 has a groove inside, and the top of the sliding block 54 has a locking block that slides in the groove. The sliding cooperation between the groove inside the top block 55 and the locking block on the top of the sliding block 54 further restricts the displacement direction of the sliding block 54, ensuring that multiple sliding blocks 54 slide synchronously and preventing the feeding hole from not sealing properly due to the shift of a single sliding block 54.

[0038] Reference Figures 1 to 3 A rotating assembly 3 is fixedly connected to the top of the mixing tank 1. The fixed connection between the top of the mixing tank 1 and the rotating assembly 3 allows the rotating assembly 3 to be stably installed above the mixing tank 1, ensuring that its power can be accurately transmitted to the rotating paddle 34 inside the mixing tank 1, and avoiding vibration displacement of the rotating assembly 3 from affecting the mixing effect. The rotating assembly 3 includes a motor 37, which serves as the power source for the rotating assembly 3 and provides initial power for the rotation of the inner shaft 31 and the outer shaft 36. Its fixed output speed can be converted into different speeds through transmission elements to meet the mixing needs of wastewater with different concentrations in the mixing tank 1, and is the core of efficient mixing.

[0039] The outer side of the motor 37 is fixedly connected to the top of the mixing tank 1. This fixed connection reduces vibration during operation and ensures stable power transmission from the motor 37 to the inner shaft 31 and outer shaft 36, preventing power transmission interruption or component damage due to vibration. The output end of the motor 37 is fixedly connected to the inner shaft 31. This connection allows the motor 37 to directly transmit power to the inner shaft 31, enabling the inner shaft 31 to rotate synchronously with the motor 37. This provides power for adjusting the angle of the rotating paddle 34 via bevel gear transmission. The bottom of the inner shaft 31 is fixedly connected to a bevel gear 32. This connection ensures that the rotation of the inner shaft 31 synchronously drives the bevel gear 32, allowing the bevel gear 32 to mesh and drive the bevel gear 33, thus providing power for adjusting the angle of the rotating paddle 34.

[0040] Multiple bevel gears 33 are meshed on the outer side of bevel gear 1 32. The meshing connection between bevel gear 1 32 and multiple bevel gears 33 allows the power of the inner shaft 31 to be transmitted to multiple bevel gears 33 simultaneously, driving multiple rotating paddles 34 to adjust their angles synchronously. This ensures that the angles of the rotating paddles 34 at different positions in the mixing tank 1 are consistent, avoiding uneven mixing. Rotating paddles 34 are fixedly connected to the outer side of multiple bevel gears 33. The fixed connection between the outer side of multiple bevel gears 33 and the rotating paddles 34 allows the rotation of bevel gears 33 to directly drive the rotating paddles 34 to rotate around their own paddle arm shaft, realizing the angle adjustment of the rotating paddles 34 to adapt to different liquid levels in the mixing tank 1, ensuring that the sediment particles at the bottom of the tank are fully agitated.

[0041] A fixed block 35 is rotatably connected to the outer side of the rotating paddle 34. The rotatable connection between the outer side of the rotating paddle 34 and the fixed block 35 allows the fixed block 35 to support the rotating paddle 34 and simultaneously allows the rotating paddle 34 to perform two actions: circular stirring motion with the outer shaft 36 and angle adjustment motion with the bevel gear 33. This ensures that the two actions do not interfere with each other. The outer shaft 36 is fixedly connected to the inner side of the fixed block 35. This fixed connection allows the rotational force of the outer shaft 36 to be transmitted to the rotating paddle 34, causing the rotating paddle 34 to perform circular motion around the central axis of the outer shaft 36. This achieves the mixing of wastewater and chemicals, ensuring rapid material fusion.

[0042] The top of the outer shaft 36 is fixedly connected to the output end of the motor 37. This fixed connection allows the motor 37 to directly power the outer shaft 36. The outer shaft 36 can obtain a different speed from the inner shaft 31 through the transmission element, flexibly adjusting the stirring intensity to adapt to different wastewater concentrations. The inner side of the outer shaft 36 is rotatably connected to the outer side of the rotating paddle 34. This rotatable connection allows the rotating paddle 34 to stir with the outer shaft 36 while ensuring efficient stirring and adaptability to different working conditions.

[0043] Working principle: When the mixer starts mixing, the fixed input speed of the motor 37 is converted into different output speeds at the load end by using a combination of transmission elements of different sizes and numbers at the output end of the motor 37. The inner shaft 31 and the outer shaft 36 rotate at different speeds. The rotation of the inner shaft 31 drives the first bevel gear 32, which in turn drives the second bevel gear 33. The second bevel gear 33 drives the rotating paddle 34 to achieve angle adjustment. Meanwhile, the outer shaft 36 drives the fixed block 35, which in turn drives the rotating paddle 34 to achieve the mixing effect.

[0044] When feeding is required, the operator starts cylinder 4. The end of cylinder 4 furthest from the output end is rotatably connected to the top of mixing tank 1. Cylinder 4 drives bearing 51 to move, and the movement of bearing 51 drives handle 52 to rotate. When handle 52 rotates, cylinder 4 also rotates. Handle 52 drives bottom block 53, and bottom block 53 drives sliding block 54. Sliding block 54 slides in the groove between bottom block 53 and top block 55, thereby rotating bottom block 53 and opening the hole to feed. When feeding is not required, cylinder 4 can be turned off.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
