Description

Technical Field

[0001] This invention relates to the field of separation technology, and more specifically to a waste treatment defoaming device. Background Technology

[0002] During waste treatment (such as wastewater), the mixing and reaction processes generate a large amount of foam. This foam occupies space in the reaction vessel, reduces the concentration of effective reactants, and thus slows down the reaction rate. Currently, the common approach is to let the foam dissipate naturally, but this takes a long time.

[0003] Therefore, this invention proposes a waste treatment defoaming device that actively eliminates foam and accelerates the production process. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a waste treatment defoaming device that can reduce or eliminate air bubbles in a liquid after mixing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a waste treatment defoaming device, comprising: The tank body includes a barrel and a top cover; The main shaft is mounted on the top cover and its bottom is located inside the tank. A filter assembly includes multiple filter units circumferentially arranged at the bottom of a main shaft. Each filter unit includes a stirring blade and a filter blade. The filter blade is hinged to the stirring blade and has filter holes. When all the filter blades are perpendicular to the main shaft and connected in sequence, a filter plate is formed. The defoaming component includes a pressure plate disposed inside the top cover. When the filter plate moves toward the pressure plate, the filter plate cooperates with the pressure plate to squeeze the foam.

[0006] Preferably, a base is fixed to the bottom of the main shaft, and the stirring blades are fixed to the side wall of the base, with the stirring blades being inclined.

[0007] Preferably, a plurality of limiting rods are movably inserted on the base. The limiting rods are U-shaped, and the end of the limiting rod away from the base is hinged to a support plate through a ball joint. When the limiting rod rises, the support plate presses the filter blade against the stirring blade.

[0008] Preferably, a bushing is fitted onto the main shaft, the bottom of the bushing is fixedly connected to a limiting rod, and the top of the bushing extends out of the tank.

[0009] Preferably, a fixed plate is rotatably mounted on the main shaft, a guide post is fixed on the fixed plate, a movable plate is rotatably mounted on the bushing, the movable plate is slidably mounted on the guide post, an electric push rod is fixed on the fixed plate, and the movable end of the electric push rod is fixedly connected to the movable plate.

[0010] Preferably, the filter blades are provided with a protrusion and a concave portion on both sides, and when the filter blades are horizontal, the protrusion of the filter blades abuts against the concave portion of the adjacent filter blades.

[0011] Preferably, the pressure plate has a cavity, and the side of the pressure plate facing the filter assembly has multiple air outlets communicating with the cavity. An air inlet pipe is provided on the top of the pressure plate, the air inlet pipe is communicating with the cavity and extends to the outside of the tank, and the air inlet pipe is connected to an air supply device.

[0012] Preferably, a drive mechanism for driving the main shaft to lift and rotate is provided on one side of the tank body. The drive mechanism includes a lifting arm, a motor is fixed to the top of the lifting arm, and the main shaft is connected to the output shaft of the motor.

[0013] Preferably, the top cover is provided with an exhaust port.

[0014] The beneficial effects of this invention are as follows: This invention incorporates a filter assembly and a defoaming assembly within the tank. As the main shaft rises within the tank, the filter blades rotate to a horizontal position under the influence of water resistance and their own gravity. All filter blades connect sequentially to form a filter plate, pushing air bubbles and foam in the liquid upwards. A pressure plate located within the top cover works in conjunction with the filter plate to compress the foam, thereby eliminating it. Furthermore, the bushing, limiting rod, and support plate designed in this invention can hold the filter blades in place, allowing them to conform to the stirring blades. This reduces the resistance during main shaft rotation and protects the filter blades from excessive water resistance that could damage the filter pores. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: like Figures 1 to 9As shown, Embodiment 1 of the present invention provides a waste treatment defoaming device, including a tank 1, which consists of a barrel 2 and a top cover 3. The top cover 3 can be fastened to the barrel 2. A support leg is fixed to the bottom of the tank 1. A lifting arm 22 is provided on one side of the tank 1. The lifting arm 22 includes a housing fixed to the ground and a support arm movably mounted on the housing. A hydraulic rod is installed inside the housing and is used to push the support arm to move within the housing. A fixing plate 14 is fixed to the support arm, and a motor 23 is mounted on the fixing plate 14. A main shaft 4 is also rotatably mounted on the fixing plate 14. The main shaft 4 is collinear with the axis of the tank 1, and the output shaft of the motor 23 is connected to the main shaft 4. The main shaft 4 passes through the top cover 3 and extends into the barrel 2. In this way, the lifting arm 22 can drive the main shaft 4 to rise and fall, while the motor 23 can drive the main shaft 4 to rotate.

[0028] The present invention has a filter assembly at the bottom of the main shaft 4, such as... Figures 5 to 9 As shown, the filter assembly includes a base 9 fixed to the bottom of the main shaft 4 and sixteen filter units circumferentially arranged on the side of the base 9. Each filter unit includes a stirring blade 5 fixed obliquely on the base 9 and a filter blade 6 hinged to the stirring blade 5. The filter blade 6 is provided with filter holes 7.

[0029] like Figure 6 As shown, the filter blade 6 has a protrusion 18 and a recess 19 on both sides. Figure 7 and Figure 9 As shown, when the filter blade 6 rotates to a horizontal position around the hinge axis, the protrusion 18 of the filter blade 6 abuts against the concave portion 19 of the adjacent filter blade 6. These sixteen filter blades 6 are assembled into a circular filter plate. When the main shaft 4 rises, it drives the filter plate to rise inside the tank 1.

[0030] In order to limit the rotation angle of the filter blade 6 and allow the filter blade 6 to naturally rotate to a horizontal state under the action of water resistance and its own weight when it rises in the solution, a limiting part can be set at the hinge shaft between the filter blade 6 and the stirring blade 5 so that the filter blade 6 cannot rotate further after it has rotated to a horizontal state.

[0031] The present invention also includes an antifoaming component, such as... Figure 2 As shown, the defoaming component of the present invention includes a pressure plate 8 fixed inside the top cover 3, and there is a gap between the pressure plate 8 and the inner wall of the top cover 3.

[0032] In use, the top cover 3 can be opened, and the raw materials to be mixed can be injected into the barrel 2. Then, the top cover 3 can be placed on the barrel 2. The lifting arm 22 controls the raising and lowering of the main shaft 4. At the same time, the motor 23 can drive the main shaft 4 to rotate, thereby causing the stirring blades 5 to rotate and rise and fall inside the barrel 2, promoting the mixing of raw materials. After mixing is completed, the motor 23 is turned off, and the height of the main shaft 4 is lowered to the minimum. At this time, the filter assembly is located at the bottom of the inner cavity of the barrel 2. Since the main shaft 4 does not rotate, the filter blades 6 rotate to a horizontal state under their own gravity to form a filter plate. Then, the lifting arm 22 raises the main shaft 4, causing the filter plate to move slowly upward. When the bubbles and foam in the solution come into contact with the filter plate, they are difficult to pass through the filter holes 7, so they are gradually lifted by the filter plate. When the bubbles and foam reach the gas-liquid interface, some of the bubbles and foam break, while others continue to be lifted. The pressure plate 8 can prevent the bubbles and foam from moving upward. The pressure plate 8, together with the filter plate, further breaks the bubbles and foam. At this time, a small amount of foam may still remain on the filter blades 6. Restart motor 23 to rotate main shaft 4. Since filter blade 6 has been removed from the solution, centrifugal force will be generated when filter blade 6 rotates, throwing the remaining foam toward the inner wall of tank 1. The foam is broken by the impact, and the defoaming is basically completed.

[0033] If foam remains in the solution, the lifting arm 22 can drive the main shaft 4 to descend. During the descent, the filter blades 6 will experience water resistance, causing them to rotate upwards and adhere to the stirring blades 5. Figure 3 and Figure 5 As shown, at this point, the spacing between the filter blades 6 is relatively large, allowing the liquid to pass through the gaps between the filter blades 6, preventing the filter holes 7 from pushing air bubbles and foam downwards. Then, the main shaft 4 is raised again to perform the aforementioned defoaming process.

[0034] Example 2: Based on Embodiment 1, this invention further proposes Embodiment 2. In this embodiment, to ensure that the filter blades 6 remain in contact with the stirring blades 5 when the main shaft 4 rotates, thereby reducing the resistance during the rotation of the main shaft 4 and protecting the filter blades 6, this invention also includes a bushing 13 fitted onto the main shaft 4. The upper end of the bushing 13 extends out of the tank body 1, and sixteen limiting rods 10 are fixed to the lower end of the bushing 13. Figure 5 and Figure 6 As shown, the limiting rod 10 is U-shaped and passes through the base 9. A ball joint seat 11 is fixed to the end of the limiting rod 10 away from the bushing 13, and a support plate 12 is hinged to the ball joint seat 11. When the bushing 13 moves on the main shaft 4, the limiting rod 10 also moves, thereby causing the support plate 12 to move. Figure 5 As shown, when the support plate 12 moves upward, it can push the filter blade 6, allowing the filter blade 6 to fit against the stirring blade 5.

[0035] To facilitate control of the lifting and lowering of the bushing 13, two guide posts 15 are fixedly installed on the fixed plate 14. A movable plate 16 is slidably installed on the guide posts 15, and the bushing 13 is rotatably engaged with the movable plate 16. An electric push rod 17 is fixed on the fixed plate 14, and the movable end of the electric push rod 17 is fixedly connected to the movable plate 16. In this way, when the electric push rod 17 extends or retracts, it can move the movable plate 16, thereby moving the bushing 13 on the main shaft 4 to adjust the position of the support plate 12.

[0036] Example 3: Based on Embodiments 1 and 2, this invention proposes Embodiment 3. In this embodiment, the pressure plate 8 is hollow, meaning a cavity is formed inside the pressure plate 8. An air inlet pipe 21 is provided on the top of the pressure plate 8, extending to the outside of the tank 1 and connecting to the air supply equipment. This allows high-pressure air from the outside to enter the cavity through the air inlet pipe 21. Multiple air outlets 20, communicating with the cavity, are provided on the side of the pressure plate 8 facing the base 9, allowing high-pressure gas to be ejected from the air outlets 20. When the filter plate is close to the pressure plate 8, air can be supplied to the air inlet pipe 21, allowing the high-pressure gas ejected from the air outlets 20 to impact and break up the bubbles and foam on the filter plate, further improving the defoaming effect. Since the introduction of high-pressure gas will cause the air pressure inside the tank 1 to increase, an exhaust port 24 is provided on the top cover 3 to allow excess gas to escape naturally, preventing the air pressure inside the tank 1 from rising.

[0037] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
