Description

Technical Field

[0001] This utility model relates to the technical field of air flotation equipment, specifically a flow stabilizing component to prevent fluctuations in the upper layer of scum in an air flotation machine. Background Technology

[0002] The air flotation machine utilizes gas to form tiny bubbles in water. These bubbles attach to suspended particles, reducing their density and causing them to float to the surface, forming a scum layer and achieving solid-liquid separation. The flow stabilization component in the air flotation machine ensures uniform water flow distribution, preventing disturbance to the scum layer due to water flow fluctuations, thus maintaining the continuous and stable rise of the scum and improving the air flotation effect.

[0003] In existing technologies, the water flow is distributed and collected evenly by arranging the positions of the water distributor and water collector, thereby reducing eddies and turbulence in the flotation tank and ensuring the stability of the water flow. Alternatively, guide plates or inclined tubes are installed inside the flotation machine to guide the water flow to rise evenly, reducing the disturbance of the scum layer by the water flow and helping the scum to rise steadily and be scraped off in a concentrated manner.

[0004] However, when using the above two solutions, an additional scum removal component is still required to periodically scrape the scum into the scum discharge trough for discharge. This will undoubtedly increase the number of components inside the air flotation equipment, making the mechanical structure of the entire equipment more complex and not conducive to the overall cleaning and maintenance of the air flotation machine. Therefore, this application provides a flow stabilization component to prevent the fluctuation of the upper layer of scum in the air flotation machine. Utility Model Content

[0005] To address the shortcomings of the existing technology, the present invention aims to provide a flow stabilizing component to prevent fluctuations in the upper layer of scum in an air flotation machine. This component can ensure a stable flow of scum, increase the efficiency of scum discharge, simplify the equipment structure, enhance the convenience of daily maintenance, make cleaning and maintenance work more efficient, and ensure the long-term stability and reliability of the entire system.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A flow stabilizing component is provided to prevent fluctuations in the upper layer of scum in an air flotation machine, including two sliding arms installed on the inner edge of the upper end of the air flotation machine, and multiple flow stabilizing arms movably installed between the two sliding arms.

[0008] The bottom of the sliding arm is fixedly installed with an L-shaped connecting seat. The L-shaped connecting seat is provided with multiple scum blowing air pipes and scum collection ports. The other end of the scum blowing air pipes is connected to an air pump through a pipe, and the other end of the scum collection port is connected to a scum collection cylinder. The end of the flow stabilizing arm is connected to a rotating shaft through a spring. The rotating shaft is rotatably mounted on a positioning block. The positioning block is detachably fixedly mounted inside the sliding arm. The bottom of the flow stabilizing arm is integrally formed with a raised edge, and the raised edges of adjacent flow stabilizing arms can abut against each other.

[0009] Furthermore, a ball-end handle is fixedly installed on the current stabilizing arm. The multiple current stabilizing arms are divided into two groups, and the two groups of current stabilizing arms are arranged alternately. The ball-end handles on the current stabilizing arms in the same group are inserted into the synchronous control arm. The rotation and swaying of the multiple current stabilizing arms in the same group are controlled by moving the synchronous control arm.

[0010] Furthermore, a linear electric cylinder for driving the synchronous control arm is installed on the top of the air flotation machine.

[0011] Furthermore, multiple electromagnets are fixedly installed on the synchronous control arm, and iron balls are provided inside the ball end handle. The electromagnets and iron balls are connected by magnetic attraction coupling.

[0012] Furthermore, a spiral conveying shaft is rotatably installed inside the slag collection cylinder, and a slag discharge pipe is connected to the lower end of the outer side of the slag collection cylinder, with the other end of the slag discharge pipe extending outward toward the air flotation machine.

[0013] Furthermore, multiple floats are fixedly installed on both sides of the flow stabilizing arm, and the floats are made of engineering plastic material with a density less than that of water.

[0014] Furthermore, the scum blowing pipe is located above the scum collection port; the air blown out from the scum blowing pipe blows the scum into the scum collection port of the sliding arm on the other side.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The flow stabilizing component for preventing fluctuations of scum on the upper layer of an air flotation machine, as exemplified by this utility model, utilizes the flexible connection of springs to allow the flow stabilizing arm to move between two sliding arms, thereby offsetting the fluctuations caused by the internal liquid flow of the air flotation machine and achieving a flow stabilizing effect. When there is too much scum on the liquid surface, the protruding edges at the bottom of the two sets of flow stabilizing arms are controlled to abut together, so that the scum is isolated and discharged separately. This replaces the use of the scum scraping component in the prior art, simplifies the structure of the equipment, makes the cleaning and maintenance of the equipment more efficient, and ensures the long-term stability and reliability of the entire system.

[0017] 2. The flow stabilizing component for preventing the fluctuation of scum on the upper layer of the air flotation machine according to the present invention has a ball-end handle that passes through the insertion hole on the synchronous control arm and is locked on the upper side of the insertion hole. It is connected by magnetic attraction between the electromagnet and the iron ball, so that the flow stabilizing arm can maintain a stable tilt state. This allows the protruding edges at the bottom of the two sets of flow stabilizing arms to be stably abutted together, so as to isolate the scum floating on the liquid surface and guide this part of the scum to be discharged without affecting the stability of the liquid surface. The effect is good.

[0018] 3. The flow stabilizing component of this utility model for preventing the fluctuation of the upper layer of scum in the flotation machine controls the rotation of the screw conveyor shaft in the scum collection cylinder to push the scum and guide it out, thereby increasing the efficiency of sewage treatment.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Furthermore, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0034] Example 1:

[0035] like Figure 1As shown, this embodiment provides a flow stabilizing component to prevent fluctuation of scum in the upper layer of an air flotation machine. It includes two sliding arms 21 installed on the inner edge of the upper end of the air flotation machine, and a plurality of flow stabilizing arms 11 are movably installed between the two sliding arms 21. The two ends of the flow stabilizing arms 11 respectively abut against the inner surfaces of the two sliding arms 21; thus preventing the sewage in the air flotation machine from flowing through the gap between the flow stabilizing arms 11 and the sliding arms 21, which would affect the subsequent discharge of scum.

[0036] like Figure 3 and Figure 5-6 As shown, an L-shaped connecting seat 23 is fixedly installed at the bottom of the sliding arm 21. The L-shaped connecting seat 23 is provided with multiple scum blowing air pipes 24 and scum collection port 26. The other end of the scum blowing air pipe 24 is connected to the air pump through a pipe, and the other end of the scum collection port 26 is connected to the scum collection cylinder 25.

[0037] The scum blowing air pipe 24 is located above the scum collection port 26; the air blown out from the scum blowing air pipe 24 blows the scum into the scum collection port 26 of the sliding arm 21 on the other side.

[0038] like Figure 4 As shown, the end of the flow stabilizing arm 11 is connected to a rotating shaft 14 via a spring 15. The rotating shaft 14 is rotatably mounted on a positioning block 22. The positioning block 22 is detachably and fixedly mounted inside the sliding arm 21. The bottom of the flow stabilizing arm 11 is integrally formed with a protruding edge 12, and the protruding edges 12 at the bottom of adjacent flow stabilizing arms 11 can abut against each other.

[0039] When using the flow stabilizing component of this application to prevent fluctuations in the upper layer of scum in an air flotation machine:

[0040] The flexible connection of the spring 15 allows the flow stabilizing arm 11 to move between the two sliding arms 21, counteracting the fluctuations caused by the liquid flow in the flotation machine and achieving a flow stabilizing effect. When there is too much scum on the liquid surface, the protruding edges 12 at the bottom of the two sets of flow stabilizing arms 11 are controlled to abut together to isolate the scum floating on the liquid surface. Then, the air pump is started so that the air blown out from the scum blowing pipe 24 blows the scum into the scum collection port 26 of the other sliding arm 21, increasing the efficiency of scum discharge.

[0041] The above solution replaces the slag scraping component in the existing technology, simplifies the equipment structure, makes the cleaning and maintenance of the equipment more efficient, and ensures the long-term stability and reliability of the entire system.

[0042] like Figure 1-2As shown, a ball-end handle 32 is fixedly installed on the flow stabilizing arm 11. The multiple flow stabilizing arms 11 are divided into two groups, and the two groups of flow stabilizing arms 11 are arranged alternately. The ball-end handles 32 on the same group of flow stabilizing arms 11 are inserted into the synchronous control arm 31. A linear electric cylinder 34 for driving the synchronous control arm 31 to move is installed on the top of the air flotation machine. When the linear electric cylinder 34 is activated, the synchronous control arm 31 is controlled to move, which drives the multiple flow stabilizing arms 11 in the same group to rotate and swing synchronously.

[0043] To enhance the current stabilization effect of the current stabilizing arm 11, such as Figure 3-4 As shown, multiple float plates 13 are fixedly installed on both sides of the flow stabilizing arm 11. The float plates 13 are made of engineering plastic material with a density less than that of water. By utilizing the characteristic that the float plates 13 can float on the water surface, the upper part of the flow stabilizing arm 11 can float on the water surface, thereby more smoothly counteracting the fluctuations caused by the liquid flow in the air flotation machine.

[0044] Example 2:

[0045] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 2 As shown in this embodiment, multiple electromagnets 33 are fixedly installed on the synchronous control arm 31, and an iron ball is provided inside the ball end handle 32. The electromagnets 33 and the iron ball are connected by magnetic attraction coupling.

[0046] The ball-end handle 32 passes through the insertion hole on the synchronous control arm 31 and is locked on the upper side of the insertion hole. The magnetic attraction coupling between the electromagnet 33 and the iron ball enables the flow stabilizing arm 11 to maintain a stable tilt state, so that the protruding edges 12 at the bottom of the two sets of flow stabilizing arms 11 are more stably abutted together, separating the scum floating on the liquid surface and guiding this part of the scum to be discharged, so that the stability of the liquid surface will not be affected by the blowing of the airflow.

[0047] Example 3:

[0048] The features that are the same as those in Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that: Figure 7 As shown, in this embodiment, a spiral conveying shaft 27 is rotatably installed inside the slag collection cylinder 25, and a slag discharge pipe is connected to the lower end of the outer side of the slag collection cylinder 25. The other end of the slag discharge pipe extends outward toward the air flotation machine.

[0049] By controlling the rotation of the screw conveyor shaft 27 inside the slag collection cylinder 25, the screw conveyor shaft 27 pushes the slag and guides it out, thereby increasing the efficiency of sewage treatment.

[0050] The rotation of the screw conveyor shaft 27 can be controlled manually, driven directly by a motor, or driven by a transmission mechanism consisting of a motor and a pulley system.

[0051] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.

[0052] Apart from the technical features described in the specification, the other technical features are known to those skilled in the art. To highlight the innovative features of this utility model, the other technical features will not be described in detail here.
