Description

Technical Field

[0001] This application relates to the field of wastewater treatment, specifically to a wastewater treatment chemical mixing device. Background Technology

[0002] When treating industrial or domestic wastewater containing large amounts of organic matter and microorganisms, wastewater treatment ponds are commonly used to treat the wastewater through biological or chemical methods. Dosing tanks are frequently used to mix the wastewater treatment agents. Conical dosing tanks are easier to drain and clean, but they require a support frame for fixation. However, to facilitate separate transport of the dosing tank and support frame and unlock transport space, they are often designed as separate units, with the tank placed directly on the support frame via an inclined support plate. This connection method makes the tank prone to vibration and shaking relative to the support frame during the mixing process, resulting in instability and potential safety risks. In contrast, integrated mixing units are inconvenient for transport and storage. Furthermore, due to the different materials used in the tank and support frame, they age and deteriorate at different rates over time, making it difficult to replace any individual component in an integrated mixing unit.

[0003] Therefore, in order to solve the above problems, this application provides a split-type chemical mixing device for wastewater treatment that facilitates the installation and separation of the dosing tank and the support. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment chemical mixing device to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment liquid mixing device, comprising a mixing tank and a support, wherein a stirring motor is inserted into the upper end of the mixing tank, and a stirring paddle extending into the mixing tank is inserted into the output end of the stirring motor; the mixing tank is placed on the inner periphery of the support, and a locking mechanism for automatically locking the mixing tank is provided inside the support.

[0006] The snap-fit ​​mechanism includes an arc-shaped snap-fit ​​plate, a transmission component, and an annular pull handle. The front end of the arc-shaped snap-fit ​​plate is provided with snap teeth, and the periphery of the mixing tank is provided with snap grooves. The arc-shaped snap-fit ​​plate is slidably connected to the inner wall of the support. The mixing tank falls along the support, and the transmission component is driven to rotate by the mixing tank. The transmission component drives the arc-shaped snap-fit ​​plate to snap into the snap groove during the displacement.

[0007] The annular pull handle is driven to move downwards, which in turn drives the transmission component to move in the opposite direction. The reverse movement of the transmission component causes the mixing tank to be lifted and separated from the support.

[0008] The locking mechanism automatically pushes the arc-shaped locking plate forward and engages with the locking slot when the transmission component is driven downward by the mixing tank. This locks the mixing tank in multiple directions, preventing it from deflecting or vibrating relative to the support during the mixing of the medicine. At the same time, the ring-shaped pull handle drives the transmission component in the opposite direction, causing the mixing tank to disengage and rise. When the support or mixing tank needs to be replaced, the operator can remove the mixing tank from the support. This effectively reduces potential safety hazards during operation and also reduces the physical labor intensity of the operators.

[0009] Furthermore, the support includes legs, a bearing inclined plate, and a guide plate. The lower end of the guide plate is welded and fixed to the upper end of the legs. The guide plates are evenly distributed around the circumference. One end of the bearing inclined plate is welded and fixed to the legs. The ends of several bearing inclined plates away from the legs are welded together to form an annular receiving groove to accommodate the lower discharge port of the mixing tank. An opening extending through to the legs is provided inside the guide plate. The opening is continuous from front to back, and the upper end of the arc-shaped locking plate has a limited sliding connection with the upper wall of the opening.

[0010] Furthermore, the locking mechanism also includes a driven pin and a spring. One end of the spring is fixedly connected to the rear end of the arc-shaped locking plate, and the other end of the spring is fixedly connected to the inner wall of the opening. One end of the driven pin is locked to the rear end of the arc-shaped locking plate and is positioned below the spring. The transmission assembly includes a support plate, a first rack, a second rack, and a gear. One end of the support plate is welded and fixed to the upper side of the first rack. Both the first rack and the second rack are slidably connected to the inner wall of the opening with a limit. Both sides of the gear are hinged to the inner wall of the opening, and both ends of the gear mesh with the first rack and the second rack, respectively.

[0011] Furthermore, a trapezoidal pin is fixedly connected to the upper end of the second rack, and an annular pull handle extending beyond the opening is welded and fixed to the upper side of the second rack. The support plate is inclined, with its inclination angle being the same as that of the lower end of the mixing tank. The support plate extends beyond the opening. The lower end of the mixing tank has an inverted conical design and a discharge port is provided at the lower end of the mixing tank, which is connected to the discharge pipe flange. The upper end of the mixing tank is provided with a feed inlet and a water inlet.

[0012] Compared with existing technologies, it has the following beneficial effects:

[0013] This utility model provides a chemical mixing device for wastewater treatment. A locking mechanism automatically pushes an arc-shaped locking plate forward and engages with a locking groove when the transmission component is driven downwards by the mixing tank. This locks the mixing tank in multiple directions, preventing it from deflecting or vibrating relative to the support during chemical mixing. Simultaneously, a ring-shaped pull handle reverses the transmission component, causing the mixing tank to disengage and rise. When the support or mixing tank needs replacement, the operator can easily remove the mixing tank from the support, effectively reducing potential safety hazards and physical labor intensity for workers.

Detailed Implementation

[0019] 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.

[0020] Please see Figures 1 to 4As shown, the present invention provides the following technical solution: a wastewater treatment liquid mixing device; including a mixing tank 1 and a support 2, a stirring motor 11 is inserted into the upper end of the mixing tank 1, a stirring paddle extending into the mixing tank 1 is inserted into the output end of the stirring motor 11, the mixing tank 1 is placed on the inner periphery of the support 2, and a locking mechanism 3 for automatically locking the mixing tank 1 is provided inside the support 2.

[0021] The snap-fit ​​mechanism 3 includes an arc-shaped snap-fit ​​plate 4, a transmission component 5, and an auxiliary lifting component. The front end of the arc-shaped snap-fit ​​plate 4 is provided with snap teeth 41, and the periphery of the mixing tank 1 is provided with a snap groove 12. The arc-shaped snap-fit ​​plate 4 is slidably connected to the inner wall of the support 2. The mixing tank 1 falls along the support 2, and the transmission component 5 is driven to rotate by the mixing tank 1. The transmission component 5 drives the arc-shaped snap-fit ​​plate 4 to snap into the snap groove 12 during displacement.

[0022] The auxiliary lifting component is driven to move downward, which drives the transmission component 5 to move in the opposite direction. The reverse movement of the transmission component 5 causes the mixing tank 1 to be lifted and separated from the support 2.

[0023] See Figure 2 The support 2 includes a support leg 21, a bearing inclined plate 22, and a guide plate 23. The lower end of the guide plate 23 is welded and fixed to the upper end of the support leg 21. The guide plate 23 is evenly arranged around the circumference. One end of the bearing inclined plate 22 is welded and fixed to the support leg 21. The ends of the bearing inclined plates 22 away from the support leg 21 are welded together to form an annular receiving groove for accommodating the lower discharge port of the mixing tank 1.

[0024] The lower end of the support leg 21 can be equipped with a universal wheel with a locking structure, so that the support 2 can drive the mixing tank 1 to move and lock it when the liquid is being mixed, making it more convenient for daily use of the mixing device.

[0025] During installation, the mixing tank is lifted above the guide plate 23, and the side wall of the mixing tank 1 is brought into contact with the upper inner wall of the guide plate 23. Then, the mixing tank 1 is released, causing it to fall along the guide plate 23 and drive the transmission component 5 to move downward. Finally, the lower end of the mixing tank 1 contacts the bearing inclined plate 22, which supports the mixing tank 1. The discharge position of the mixing tank 1 then enters the annular receiving groove.

[0026] As another embodiment, such as Figure 3 as well as Figure 4 As shown, the guide plate 23 has an opening 231 that extends through to the support leg 21. The opening 231 is open from front to back, and the upper end of the arc-shaped snap-fit ​​plate 4 has a limited sliding connection with the upper wall of the opening 231.

[0027] The sliding connection between the arc-shaped snap-fit ​​plate 4 and the upper wall of the opening 231 allows the arc-shaped snap-fit ​​plate 4 to slide along the upper wall of the opening 231, extending out of the opening 231 or retracting into the opening 231.

[0028] See Figure 4 The locking mechanism 3 also includes a follower pin 31 and a spring 32. One end of the spring 32 is fixedly connected to the rear end of the arc-shaped locking plate 4, and the other end of the spring 32 is fixedly connected to the inner wall of the opening 231. One end of the follower pin 31 is locked to the rear end of the arc-shaped locking plate 4, and the follower pin 31 is positioned below the spring 32. The spring 32 always provides a backward pulling force to the arc-shaped locking plate 4, so that the arc-shaped locking plate 4 has a tendency to move backward into the opening 231, so that the arc-shaped locking plate 4 maintains a retracted shape in the opening 231 under normal conditions. Since the spring 32 provides a pulling force, the spring 32 can be directly used in the design without limiting the spring 32 in other directions.

[0029] See Figure 3 as well as Figure 4 The transmission assembly 5 includes a support plate 51, a first rack 52, a second rack 53, and a gear 54. One end of the support plate 51 is welded and fixed to the upper side of the first rack 52. The first rack 52 and the second rack 53 are both slidably connected to the inner wall of the opening 231 with a limit. The two sides of the gear 54 are hinged to the inner wall of the opening 231, and the two ends of the gear 54 are respectively engaged with the first rack 52 and the second rack 53.

[0030] Among them, the first rack 52 and the second rack 53 are only limited and can only move in the vertical direction. The limiting method is preferably the limiting method of sliding track. When the mixing tank 1 is not installed, the upper end of the first rack 52 is located above the opening 231, and the gear 54 is positioned at the connection between the guide plate 23 and the support leg 21.

[0031] The support plate 51 is positioned below the arc-shaped snap-fit ​​plate 4. When the mixing tank 1 moves down, it drives the support plate 51 to move downward, which in turn drives the first rack 52 to slide downward along the opening 231. The movement of the first rack 52 drives the gear 54 to rotate, which in turn drives the second rack 53 to slide upward.

[0032] See Figure 4 A trapezoidal pin 55 is fixedly connected to the upper end of the second rack 53, and an annular pull handle 6 extending out of the opening 231 is welded and fixed to the upper side of the second rack 53.

[0033] When the second rack 53 is driven upward by the gear 54, its upper trapezoidal pin 55 contacts the driven pin 31 at the rear end of the arc-shaped locking plate 4 and uses its inclined surface to drive the driven pin 31 to move horizontally, so that the driven pin 31 pushes the arc-shaped locking plate 4 to protrude from the opening 231 and engage with the locking groove 12 on the periphery of the mixing tank 1; thereby achieving multi-directional limiting of the mixing tank 1 and preventing it from deflecting during the mixing operation.

[0034] It should be noted that the reason why the upper end of the first rack 52 can remain above the opening 231 when the mixing tank 1 is not installed is that the annular pull handle 6 connected to the rear end of the second rack 53 has a higher overall weight. Under the action of gravity, the second rack 53 can overcome the gravity of the first rack 52 and be in a lower position.

[0035] Furthermore, when it is necessary to separate the support 2 and the mixing tank 1 for replacement, pressing down the annular pull handle 6 can synchronously drive the second rack 53 of the array to move downwards. The displacement of the second rack 53 drives the gear 54 to rotate in the opposite direction, thereby causing the first rack 52 to slide upwards, causing the support plate 51 to move vertically upwards in sync. The displacement of the second rack 53 causes the trapezoidal pin 55 to disengage from the driven pin 31, and the spring 32 releases the accumulated elastic potential energy to pull the arc-shaped snap-fit ​​plate 4 back into the opening 231. Subsequently, the support plate 51 drives the mixing tank 1 to move upwards, and the mixing tank 1 can be removed.

[0036] It should be noted that the support plate 51 is inclined, and its inclination angle is the same as that of the lower end of the mixing tank 1. The support plate 51 extends to the outside of the opening 231.

[0037] Furthermore, the lower end of the mixing tank 1 is designed with an inverted cone shape, and a discharge port 13 is provided at the lower end of the mixing tank 1. The discharge port 13 is connected to the discharge pipe flange. The mixed medicine solution can be discharged through the discharge port 13.

[0038] Meanwhile, the upper end of the mixing tank 1 is provided with a feed inlet and a water inlet for feeding the mixture into the mixing tank 1.

[0039] Working principle: During installation, the side wall of the mixing tank 1 is attached to the upper inner wall of all the guide plates 23. Then the mixing tank 1 is released, so that the mixing tank 1 falls along the guide plate 23 and drives the bearing plate 51 and the first rack 52 to slide downward along the opening 231. The rotation of the gear 54 drives the second rack 53 to slide upward, so that the trapezoidal pin 55 pushes the driven pin 31 and the arc-shaped snap-fit ​​plate 4 to protrude from the opening 231 and snap into the snap-fit ​​groove 12 on the periphery of the mixing tank 1.

[0040] When it is necessary to separate the support 2 and the mixing tank 1, the downward pressure of the ring handle 6 drives the second rack 53 of the gear array to move downward synchronously, causing the gear 54 to rotate in the opposite direction, which drives the first rack 52 and the support plate 51 to move vertically upward synchronously, and causes the trapezoidal pin 55 to disengage from the driven pin 31. The spring 32 releases the accumulated elastic potential energy and pulls the arc-shaped snap-fit ​​plate 4 back into the opening 231. Then the support plate 51 drives the mixing tank 1 to move upward, and the mixing tank 1 can be removed.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
