Description

Technical Field

[0001] The present invention discloses a flotation machine sewage discharger and an air flotation machine, and relates to a sewage discharger used on the air flotation machine, and belongs to the technical field of sewage treatment, and particularly relates to a sewage discharger which discharges sewage through a spiral rising sewage discharge pipe, is convenient for pressure relief, and is convenient for discharging sewage and floccules by thickening the other end of the sewage discharge pipe, and is convenient for disassembly and maintenance by designing that the sewage discharge pipe is detachable. Background Art

[0002] Air flotation machine is a kind of equipment used for water treatment, mainly used in chemical plants, drinking water treatment, industrial wastewater treatment and other fields. Its working principle is to inject air or other gases into the water to generate a large number of tiny bubbles, and use these bubbles to adsorb impurities such as suspended matter, grease, etc. that are difficult to remove by natural sedimentation or floating in the water, so that they float on the water surface, thereby achieving solid-liquid separation. The traditional air flotation machine mainly includes components such as dosing device, dissolved air system, air flotation tank and scraping mechanism. The sewage first enters the reaction tank and mixes with the added flocculant to produce flocculation reaction, and then enters the contact tank and combines with the tiny bubbles in the dissolved air water to form floccules, enters the separation tank and floats to the water surface to form scum, and finally the scum is scraped into the scum collecting tank by the scraping mechanism for discharge. However, in traditional flotation machines, flocculants are added into the reaction tank through a dosing device. When the flocculants are added, they only exist in a certain position of the reaction tank, and the addition is uneven. Since the sewage continuously flows into the reaction tank at a certain flow rate, the sewage and the flocculant cannot fully contact each other before entering the next link, so that part of the sewage cannot be flocculated and floccules cannot be produced, resulting in low sewage treatment efficiency and poor treatment effect; and the tiny bubbles generated in the dissolved air system are also only concentrated in a certain position of the contact tank and cannot quickly diffuse to various areas of the contact tank, resulting in some floccules cannot be fully bonded with the tiny bubbles and cannot produce scum, resulting in low sewage treatment efficiency and poor treatment effect.

[0003] Announcement No. CN217895336U discloses a flotation machine with a sludge dewatering device, including an equipment body, the equipment body is divided into a dosing pretreatment unit, a flotation reaction treatment unit and a sludge dewatering treatment unit by a stainless steel partition, the dosing pretreatment unit includes a coagulant dosing reaction zone and a coagulant dosing reaction zone, the flotation reaction treatment unit is provided with a perforated water distribution pipeline, a dissolved air releaser, a mud discharge pipeline, an emptying pipeline, a slag scraping device, and a slag collection tank, and the sludge dewatering treatment unit includes a dehydration rotating motor and a dewatering tank. The above-mentioned flotation machine is provided with a coagulant dosing reaction zone agitator and a coagulant dosing reaction agitator, which can promote the full contact between sewage and flocculants and produce more floccules, but the tiny bubbles generated by the dissolved air tank in the above-mentioned flotation machine are only concentrated at a certain position of the equipment body through the dissolved air releaser, and cannot be quickly diffused to various areas of the equipment body, resulting in that some floccules cannot be fully bonded with the tiny bubbles and cannot produce slag, thereby resulting in low sewage treatment efficiency and poor treatment effect.

[0004] The applicant has designed an air flotation machine to solve the above problems. The flocculation component allows sewage and flocculants to fully contact to produce flocs. The contact component allows flocs with a density less than that of water to fully bond with tiny bubbles to form foam flocs. Finally, the separation component realizes solid-liquid separation. The air flotation machine discharges sewage and foam flocs from the contact box to the separation tank through a sewage discharge pipe. However, the sewage discharge pipe has a short body and a thin diameter, so the air pressure in the contact box cannot be released, and the foam flocs are easily blocked at the pipe mouth, affecting the sewage treatment efficiency. Moreover, it cannot be disassembled and is not convenient for maintenance. Summary of the invention

DETAILED DESCRIPTION Example 1

[0013] The present invention discloses a flotation machine sewage discharger, which is composed of a sewage discharge pipe (9), a clamping groove (33), a clamping block (34) and a protective cover (35). One end of a sewage pipe (9) is disposed on the side surface of the contact box (17) in correspondence with each other, and one end of the sewage pipe (9) is connected to the contact box (17). One end of the sewage discharge pipe (9) is close to the top surface of the contact box (17). The other end of the sewage discharge pipe (9) passes through a through hole opened on the other side of the separation tank (1) and is located inside the separation tank (1). The sewage discharge pipe (9) is a spiral ascending structure with multiple arc bends, and the inner wall of the sewage discharge pipe (9) is rough. The inner diameter of the sewage discharge pipe (9) gradually increases from one end connected to the contact box (17) to the other end. The bend of the sewage pipe (9) is a hose. The inner wall of the sewage pipe (9) is the thickest at the bend, followed by the inner wall between the multiple bends and between the bends and the two ends, and the two ends are the thinnest. Preferably, the inner diameter of the sewage pipe (9) at the bend is larger than the inner diameters at both ends of the bend. Preferably, the sewage pipe (9) is a spliced ​​structure, and the sewage pipe (9) is formed by splicing two branch sewage pipes (32) together. One end of one of the two branch sewage pipes (32) is connected to the contact box (17), and one end of the other branch sewage pipe (32) is connected to the separation tank (1). The other end of one of the two branch sewage pipes (32) is provided with a buckle, wherein the buckle is a circular ring structure with multiple arc-shaped bends and undulations. The other end of the other of the two branch sewage pipes (32) is provided with a clamping groove (33), and the shape of the clamping groove (33) corresponds to the buckle. The two branch sewage pipes (32) are connected to each other via a clamping groove (33) and a buckle, and the buckle and the clamping groove (33) are arranged on the sewage pipe (9) except for the bending part. A protective sleeve (35) is placed at the connection between the sewage pipes (9), and the protective sleeve (35) is a circular ring structure. Preferably, the number of the branch sewage pipes (32) can be greater than 2; When in use, the protective cover (35) is inserted into one end of the sewage pipe (9), and then the sewage pipes (9) are spliced ​​in pairs, and the protective cover (35) is pushed back to the connection of the sewage pipe (9). The sewage is discharged from the contact box (17) and enters the sewage pipe (9), where it is buffered in the spiral pipe to prevent the air pressure contained in the sewage from affecting the treatment effect in the separation tank (1). Then, it is discharged to the separation tank (1) along the sewage pipe (9). When cleaning, the two ends of the sewage pipe (9) are taken out of the air flotation machine, and then the protective cover (35) is taken out respectively. The branch sewage pipe (32) is disassembled along the mortise and tenon structure, and the branch sewage pipe (32) is cleaned respectively. This facilitates disassembly and maintenance, and can release air pressure. In addition, the thickened design of the other end of the sewage pipe (9) facilitates the discharge of sewage and floccules, thereby improving the sewage treatment efficiency. Example 2

[0014] The difference between this embodiment and embodiment 1 is that: the inner wall of the sewage pipe (9) is provided with a plurality of groups of trapezoidal protrusions (36), the plurality of groups of trapezoidal protrusions (36) are arranged equidistantly along the circumference of the sewage pipe (9), a group of the trapezoidal protrusions (36) has a plurality of the trapezoidal protrusions (36), the plurality of the trapezoidal protrusions (36) in the same group are arranged equidistantly along the axial direction of the sewage pipe (9), the two adjacent groups of trapezoidal protrusions (36) are arranged in a staggered manner, the large bottom surface of the trapezoidal protrusions (36) is connected to the inner wall of the sewage pipe (9), and the small bottom surface of the trapezoidal protrusions (36) extends toward the center of the sewage pipe (9); when in use, the trapezoidal protrusions (36) can increase the inner wall strength of the sewage pipe (9), making it more durable and able to withstand greater pressure and impact, increase the turbulence of the sewage with air pressure, facilitate pressure relief, increase the effective surface area of ​​the inner wall of the pipe, and improve the performance of the sewage pipe (9). Example 3

[0015] The difference between this embodiment and embodiment 1 is that: the inner wall of the sewage pipe (9) is provided with a plurality of groups of conical protrusions (37), the plurality of groups of conical protrusions (37) are arranged equidistantly along the circumference of the sewage pipe (9), a group of the conical protrusions (37) has a plurality of the conical protrusions (37), the plurality of the conical protrusions (37) in the same group are arranged equidistantly along the axial direction of the sewage pipe (9), the two adjacent groups of conical protrusions (37) are arranged in a staggered manner, the bottom surfaces of the conical protrusions (37) are connected to the inner wall of the sewage pipe (9), and the edges of the conical protrusions (37) extend toward the center of the sewage pipe (9); the design of the conical protrusions (37) can prevent solid particles or other impurities from accumulating and clogging in the pipeline, thereby keeping the pipeline unobstructed, and the conical design also facilitates sewage to pass through both sides of the protrusions, thereby facilitating diversion; The sewage pipe (9) is designed with a spiral ascending structure with multiple arc bends, so that the liquid can be discharged from the pipe more quickly, reducing the possibility of water accumulation and blockage, reducing the frequency of pipe cleaning and maintenance, saving maintenance costs and time, and being able to improve the slope of the sewage pipe (9), ensuring smooth sewage discharge and avoiding dead corners, thereby improving the sewage discharge effect; The design of the inner diameter of the sewage pipe (9) gradually increasing from one end connected to the contact box (17) to the other end can reduce the resistance of liquid flow, reduce the possibility of solid particles or impurities depositing and clogging in the pipe, reduce the frequency of cleaning and maintenance, reduce maintenance costs, and improve drainage efficiency; The bend of the sewage pipe (9) is designed to be a hose. When the sewage with air pressure flows through the bend of the hose, the hose will deform, increasing the inner diameter of the pipe, thereby avoiding blockage caused by the deposition of impurities in the sewage. The inner wall of the sewage pipe (9) is thickest at the bend, followed by the thickness between the multiple bends and between the bends and the two ends. The two ends are designed to be thinnest. The thick inner wall at the bend can strengthen the stress-bearing part and prevent the pipe wall from breaking or deforming under the action of water pressure and bending stress; the two ends are thinnest, which can optimize fluid flow and reduce sewage discharge resistance. The sewage pipe (9) is designed such that the inner diameter at the bend is larger than the inner diameters at both ends of the bend. The changing inner diameter can change the flow direction of the sewage and reduce the risk of impurities and sediments in the sewage clogging the pipe. At the same time, the difference in inner diameter facilitates cleaning and unblocking of the pipe. The sewage pipe (9) is designed as a spliced ​​structure, which is easy to install and disassemble, convenient for cleaning, maintenance or replacement of pipeline components, and reduces the difficulty and cost of maintenance. The mortise and tenon structure can provide a tighter connection, reduce the risk of leakage, and ensure the sealing of the pipeline system; The buckle is designed with a circular ring structure with multiple arc bends and undulations, which can increase the contact area and friction, prevent the buckle from sliding or falling off during use, improve the firmness and stability of the buckle, and ensure that the connection part is not easy to loosen or fall off; The design of the protective sleeve (35) being provided at the joint between the branch sewage pipes (32) can increase the sealing performance, reduce the risk of leakage at the connection of the sewage pipe (9), maintain the airtightness of the pipeline system, and reduce the possibility of the sewage pipe (9) being subjected to external impact, wear or damage during installation or use; The design of the sewage pipe (9) being formed by connecting two branch sewage pipes (32) together can realize modular combination, and is convenient for flexible matching and expansion according to the size of the distance, making the installation of the sewage pipe (9) simpler and more convenient, facilitating the maintenance and repair of the pipeline system, and reducing the risk of affecting the operation of the overall system.

[0016] The purpose is to discharge sewage through the spirally ascending sewage pipe (9) to facilitate pressure relief. By thickening the other end of the sewage pipe (9), it is convenient to discharge sewage and flocs. By designing the branch sewage pipe (32) to be detachable, it is convenient to disassemble and repair.
