Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam suction machine technology, specifically a pulse foam suction machine. Background Technology
[0002] In wastewater treatment processes, sludge-containing foam often floats on the surface of biological treatment tanks. If this foam is not removed in time, it will dry out under the sun and wind, accumulating more and more on the water surface, eventually covering the entire tank surface, becoming a breeding ground for flies, releasing foul odors, and causing environmental pollution.
[0003] Chinese patent disclosure of "a pulsating foam suction machine", announcement number CN102145933 A, includes a flow guide tube and an impeller at the bottom driven by a motor to drain water downwards. The upper part of the flow guide tube is above the water level. The foam suction port of the flow guide tube is submerged in the water and quickly filled by the surrounding foam and sludge. This allows the foam and sludge on the water surface to be collected into the tube and sent underwater, causing the sludge to settle.
[0004] However, the working radius of the aforementioned patented guide tube for adsorbing floating mud is small, and the foam is only driven into the guide tube by the spontaneous flow of water, resulting in a decrease in foam adsorption efficiency. In addition, the aforementioned patented impeller does not have a filter component, so impurities in the water can easily enter the guide tube and become entangled on the impeller, thus affecting the operation of the impeller. Utility Model Content
[0005] The purpose of this invention is to provide a pulsed foam suction machine to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pulsating foam suction machine, comprising a guide tube, the inner wall of which is fixedly connected to a fixed frame, the outer side of which is fixedly connected to a motor, the output end of which is fixedly connected to a drive shaft, the top of which is rotatably connected to a top plate, the top of which is fixedly connected to a connecting ring, a traction rope being provided on the connecting ring, the outer side of which is fixedly connected to a float plate, the inner wall of which is fixedly connected to a filter plate, a discharge port and a water outlet being provided on the outer side of which, the bottom of which extends to the bottom of which is fixedly connected to a cleaning plate, the outer side of which is fixedly connected to a limiting strip, a sleeve being fitted over the outer side of which has a limiting groove inside, and a scraper being fixedly connected to the outer side of which.
[0007] Preferably, the guide tube is connected and fixed to the motor via a fixing frame, and the water outlet holes are evenly distributed in a circumferential array on the outside of the guide tube.
[0008] Preferably, the outer side of the drive shaft is slidably connected to the limiting groove via a limiting strip, and the scraper is evenly distributed in a circumferential array on the outer side of the sleeve.
[0009] Preferably, the filter plate is inclined downward at the edge, the filter plate is rotatably connected to the outside of the drive shaft through a sealed bearing, a plurality of discharge ports are opened on the outside of the guide tube, and the surface of the filter plate is smooth and communicates with the discharge ports.
[0010] Preferably, the scraper is an arc-shaped plate, the scraper is hollow inside to provide buoyancy, and the bottom of the scraper has a relief groove to avoid collision with the floating plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention uses a motor to drive the impeller, which in turn rotates the scraper. The rotation of the arc-shaped scraper effectively expands the foam suction range of the guide tube. The rotation of the scraper accelerates the flow of foam into the guide tube, thereby improving the foam suction efficiency of the guide tube. The cooperation of the limiting groove and the limiting strip ensures the rotation effect of the scraper. At the same time, the hollow design inside the scraper provides buoyancy, ensuring that the scraper always stays on the water surface, thus ensuring the foam diversion effect.
[0013] This invention also uses a motor to drive the drive shaft to rotate, causing the impeller to rotate and generate thrust to drive the water flow into the guide tube. The filter plate filters the impurities in the water, preventing them from entering the guide tube and getting entangled on the impeller or clogging the drain hole. The inclined filter plate discharges the filtered impurities from the discharge port to prevent the filter plate from clogging. The drive shaft causes the cleaning plate to rotate and clean the drain hole to prevent clogging. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-5 This utility model provides a technical solution: a pulsating foam suction machine, including a guide tube 1, the inner wall of the guide tube 1 is welded and fixed to a fixed frame 2, a through cylindrical groove is opened at the top of the guide tube 1, the outer side of the fixed frame 2 is connected and fixed to a motor 3, the output end of the motor 3 is welded and fixed to a drive shaft 4, the outer side of the drive shaft 4 is welded and fixed to an impeller, the bottom of the drive shaft 4 extends to the bottom of the guide tube 1 and is fixedly connected to a cleaning plate 12, the top of the motor 3 extends to the outer side of the guide tube 1 and is rotatably connected to the bottom surface of a top plate 5, and the top of the top plate 5 is connected to two... The connecting ring 6 is welded and fixed, and a traction rope 7 is installed on the connecting ring 6. The outer side of the guide cylinder 1 is welded and fixed to several floats 8. The inner wall of the guide cylinder 1 is welded and fixed to the filter plate 9. A discharge port 10 and a water outlet 11 are opened on the outer side of the guide cylinder 1. The bottom of the motor 3 extends to the bottom of the guide cylinder 1 and is welded and fixed to the cleaning plate 12. The outer side of the drive shaft 4 is welded and fixed to the limiting strip 13. A sleeve 14 is fitted on the outer side of the limiting strip 13. A limiting groove 15 is opened inside the sleeve 14. The outer side of the sleeve 14 is welded and fixed to the scraper 16.
[0022] The guide tube 1 is connected and fixed to the motor 3 via the fixing bracket 2. The water outlet holes 11 are evenly distributed in a circular array on the outside of the guide tube 1. The water outlet holes 11 allow the thrust generated by the rotation of the impeller on the outside of the drive shaft 4 to cause water to overflow. The water outlet holes 11 also prevent impurities and dirt in the water from entering the guide tube 1 and causing damage.
[0023] The filter plate 9 has its edges angled downwards. It is rotatably connected to the outer side of the drive shaft 4 via a sealed bearing. Several discharge ports 10 are opened on the outer side of the guide cylinder 1. The surface of the filter plate 9 is smooth and communicates with the discharge ports 10. The impeller generates thrust, causing water carrying foam into the guide cylinder 1 and then discharging it through the outlet holes 11 on the outer side of the guide cylinder 1. The incoming water passes through the filter plate 9, filtering out impurities or debris. The water then exits through the discharge ports 10 via the angled surface of the filter plate 9. An angled side plate (not shown in the diagram) is also provided on the outer side of the drive shaft 4. The side plate is in contact with the surface of the filter plate 9. The rotation of the drive shaft 4 synchronously drives the side plate to rotate, cleaning impurities adhering to the surface of the filter plate 9 and facilitating the discharge of filtered impurities from the discharge ports 10.
[0024] The drive shaft 4 is slidably connected to the limiting groove 15 via the limiting strip 13. The scrapers 16 are evenly distributed in a circumferential array on the outside of the sleeve 14. The scrapers 16 are arc-shaped plates, and the interior of the scrapers 16 is hollow to provide buoyancy. The bottom of the scrapers 16 has a relief groove 17 to avoid collision with the floating plate 8. The arc-shaped plate design of the scrapers 16 ensures that the scrapers 16 can drive the foam to flow towards the central guide tube 1 while rotating.
[0025] Working principle: During use, one end of the traction rope 7 is connected and fixed to the connecting ring 6, and the other end is connected to the fixed point. This facilitates the movement of the guide tube 1 and ensures that the guide tube 1 will not sink when it is raised or lowered. The float plate 8 provides buoyancy to the guide tube 1 as a whole. The motor 3 drives the drive shaft 4 to rotate, and the impeller generates thrust to discharge water from the outlet hole 11 on the outside of the guide tube 1. The water then flows in from the top of the guide tube 1. The drive shaft 4 drives the scraper 16 to rotate. The rotation of the arc-shaped scraper 16 guides a larger area of foam to the top of the guide tube 1 in the center. The scraper 16 is hollow inside and provides buoyancy. When the guide tube 1 and the motor 3 move up and down, the sleeve 14 slides up and down with the outside of the motor 3 through the limiting groove 15. The sleeve 14 drives the scraper 16 to rotate while ensuring that the scraper 16 is properly positioned above the water surface, further ensuring the guiding effect of the scraper 16 on the foam.
