Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, and in particular to a device for treating residual wastewater from domestic garbage. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of urban domestic waste generated is increasing. These wastes contain a large amount of organic matter and water, especially in kitchen waste. When these wastes are collected, transported and treated, a certain amount of wastewater will be generated. This wastewater usually contains high concentrations of organic matter, suspended solids, grease and other harmful chemicals, posing a serious threat to the environment. If it is discharged directly without proper treatment, it will not only pollute surface water and groundwater, but may also affect soil quality and even endanger human health.

[0003] As an effective solid-liquid separation method, flotation technology has been widely used in the field of wastewater treatment in recent years. This technology uses the collision and adhesion of tiny bubbles with suspended particles in the wastewater to bring these particles to the water surface to form scum, which is then removed by a scraper or other means to achieve the purpose of purifying water quality.

[0004] In the traditional flotation machine structure, in order to improve the effect of flotation treatment of impurities in wastewater, a large number of aeration valves need to be arranged along the water flow direction at the bottom of the flotation tank, so as to generate a large number of bubbles in the wastewater to flotate the impurities.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 6As shown, a domestic waste residual wastewater treatment equipment of the present invention comprises a wastewater treatment tower 1, an inlet pipe 2, an overflow pipe 3, a slag discharge channel 4 and a bubble discharge structure 6, wherein the wastewater treatment tower 1 is vertical, the inlet pipe 2 is installed at the top of the wastewater treatment tower 1, the overflow pipe 3 is installed at the top of the wastewater treatment tower 1, wastewater enters the wastewater treatment tower 1 from the inlet pipe 2 and flows downward, and then is discharged through the overflow pipe 3, the slag discharge channel 4 is installed on the side wall of the wastewater treatment tower 1 and is connected with the inside of the wastewater treatment tower 1, multiple groups of guide structures 5 are arranged on the left and right sides of the wastewater treatment tower 1, and the multiple groups of guide structures 5 on the inner side of the wastewater treatment tower 1 are arranged vertically, the positions of the guide structures 5 on the left and right sides of the wastewater treatment tower 1 are staggered, and the bubble discharge structure 6 is installed at the bottom of the wastewater treatment tower 1 and is used to discharge bubbles into the wastewater treatment tower 1; Among them, the overflow pipe 3 is used to limit the water level height in the wastewater treatment tower 1, the slag discharge channel 4 is higher than the water surface in the wastewater treatment tower 1, and the diversion structure 5 sucks the water in the wastewater treatment tower 1 through the input end located on its upper side and transports it downward, and then the diversion structure 5 discharges the water back into the wastewater treatment tower 1 through the output end located on its lower side. The coordinated use of multiple groups of diversion structures 5 on the left and right sides of the wastewater treatment tower 1 can make the water in the wastewater treatment tower 1 flow downward in an S shape.

[0020] In detail, the arrangement of the overflow pipe 3 can help retain a sufficient amount of water in the wastewater treatment tower 1, that is, the wastewater level in the wastewater treatment tower 1 is fixed, the water inlet pipe 2 can continuously supply water to the wastewater treatment tower 1, and the wastewater in the wastewater treatment tower 1 is in a downward flow state as a whole. The connection position between the slag discharge channel 4 and the wastewater treatment tower 1 is higher than the water level in the wastewater treatment tower 1, thereby preventing the wastewater from being discharged through the slag discharge channel 4. The diversion structure 5 is used to suck the wastewater in the wastewater treatment tower 1 and transport it downward, and then discharge it horizontally into the wastewater treatment tower 1. Since the positions of the diversion structures 5 on the left and right sides of the wastewater treatment tower 1 are staggered, the water discharged from the diversion structure 5 on one side of the wastewater treatment tower 1 can enter the diversion structure 5 on the other side of the wastewater treatment tower 1, thereby realizing the wastewater in the wastewater treatment tower 1, through the coordinated use of multiple groups of guide structures 5 on the left and right sides of the wastewater treatment tower 1, the wastewater can pass through the multiple groups of guide structures 5 in sequence and be transported downward. At this time, the wastewater is in an S-shaped flow state in the wastewater treatment tower 1. The bubble exhaust structure 6 can supply bubbles into the wastewater in the wastewater treatment tower 1, and the bubbles will form a bubble curtain to float upward. When the wastewater flows horizontally and passes through the bubble curtain, the bubbles will complete a flotation treatment on the wastewater, that is, the impurities in the wastewater will be adsorbed by the bubbles and float up with the help of the bubbles. Since the wastewater is guided by the multiple groups of guide structures 5 to perform S-shaped flow, the wastewater will repeatedly pass through the bubble curtain located in the middle of the wastewater treatment tower 1 while flowing downward, thereby performing multiple and repeated flotation operations on the wastewater through the bubbles.

[0021] Based on the above embodiment, since the bubbles will repeatedly perform flotation treatment on the horizontally flowing wastewater when floating up, it is convenient to make the bubbles and the wastewater intersect multiple times, realize the continuous adsorption of impurities in the wastewater by the bubbles, and facilitate the full use of the bubbles. Moreover, since the water flow in the wastewater treatment tower 1 is in a vertical flow state as a whole, the contact time between the bubbles and the wastewater can be extended, thereby improving the flotation effect.

[0022] It should be pointed out that when the scum floats to the water surface, as the scum gradually increases, the height of the scum rises. When it reaches the height position of the scum discharge channel 4, the scum can be naturally discharged through the scum discharge channel 4.

[0023] By designing that the wastewater flows vertically in an S-shape in the wastewater treatment tower 1, it is convenient for the wastewater to pass through the bubble curtain formed by the floating bubbles discharged by the bubble discharge structure 6 for multiple times in the horizontal direction, so that the wastewater and the bubbles form a multiple intersection flotation effect, which increases the contact time between the wastewater and the bubbles, improves the adsorption efficiency of the bubbles on the suspended impurities, and reduces the waste of bubbles; by arranging staggered guide structures 5 at different heights of the flotation machine, the lateral transportation of the wastewater is realized, so that the wastewater can pass through the bubble curtain for multiple times in the wastewater treatment tower 1, thereby enhancing the treatment capacity of the flotation machine; the design of the S-shaped flow path and the overall vertical flow trajectory of the wastewater in the wastewater treatment tower 1 make the whole system more compact, reduce the floor space, and adapt to the space limitation of the wastewater treatment plant, and its structure is simple and easy to operate; in summary, the technical solution improves the bubble utilization rate, prolongs the contact time between the bubbles and the wastewater, simplifies the equipment and reduces the operating cost by improving the internal structure and water flow path of the flotation machine, thereby effectively solving the problems existing in the traditional flotation machine.

[0024] Furthermore, the guide structure 5 includes a vertical cylinder 7 and two water guide channels 8 connected and installed on the upper and lower sides of the cylinder 7 . Both water guide channels 8 are connected to the wastewater treatment tower 1 . A spiral plate 9 is rotatably arranged in the cylinder 7 .

[0025] In detail, when the spiral plate 9 rotates, it can push the wastewater in the vertical cylinder 7 to flow downward. At this time, the wastewater in the wastewater treatment tower 1 will naturally flow into the vertical cylinder 7 through the water guide channel 8 on the upper side, and the wastewater on the lower side of the vertical cylinder 7 will flow back into the wastewater treatment tower 1 through the water guide channel 8 on the lower side of the vertical cylinder 7, thereby realizing the lateral drainage of the wastewater and facilitating the guidance of the flow direction of the wastewater.

[0026] Furthermore, the water inlet pipe 2 is fixed to the top of the wastewater treatment tower 1 through a fixing frame 25, and a secondary pipe 10 is sleeved on the outside of the water inlet pipe 2. A guide hopper 11 is provided at the bottom of the secondary pipe 10, and the guide hopper 11 is connected to the secondary pipe 10 through a connecting plate 12; The guide scoop 11 is conical in shape, and the opening of the guide scoop 11 faces upward.

[0027] In detail, the auxiliary pipe 10 is connected to the water inlet pipe 2, and the guide bucket 11 is fixed on the auxiliary pipe 10 through the connecting plate 12. The guide bucket 11 is immersed in the wastewater in the wastewater treatment tower 1. The wastewater in the water inlet pipe 2 can be introduced into the guide bucket 11 through the auxiliary pipe 10. The wastewater in the guide bucket 11 flows upward through the gap between the guide bucket 11 and the outer wall of the auxiliary pipe 10 and is discharged into the wastewater treatment tower 1, thereby realizing the wastewater supply work, and through the setting of the guide bucket 11, the scum in the wastewater can be prevented from floating up and entering the auxiliary pipe 10, thereby guiding and blocking the scum, and the conical setting of the guide bucket 11 can help the scum avoid the guide bucket 11 and float to the water surface.

[0028] Furthermore, the water inlet pipe 2 is located above the wastewater treatment tower 1, the auxiliary pipe 10 passes through the wastewater treatment tower 1, and the auxiliary pipe 10 and the water inlet pipe 2 are slidably connected to each other; A vibration structure is provided between the auxiliary pipe 10 and the water inlet pipe 2 , and the vibration structure is used to provide vibration power for the auxiliary pipe 10 and the guide bucket 11 .

[0029] In detail, by vibrating the auxiliary pipe 10 and the guide bucket 11, the scum in the wastewater and the scum on the water surface can be prevented from being adsorbed on the auxiliary pipe 10 and the guide bucket 11, and when the auxiliary pipe 10 vibrates, it will form ripples on the water surface. The ripples can be used to drag the scum away from the auxiliary pipe 10, thereby preventing the scum from being deposited on the auxiliary pipe 10.

[0030] Furthermore, a plurality of fan blades 13 are arranged in the auxiliary pipe 10; The wastewater treatment tower 1 is provided with a transmission structure, which is used to make the auxiliary pipe 10 and the spiral plate 9 in each group of diversion structures 5 rotate synchronously, and the transmission structure includes a transmission ring 14 and two transmission wheels 15, the transmission ring 14 is sleeved on the outer wall of the auxiliary pipe 10, and the transmission ring 14 is rotatably installed on the top of the wastewater treatment tower 1, and the transmission ring 14 and the two transmission wheels 15 are connected by a transmission belt 16, and each transmission wheel 15 is provided with a transmission shaft 17, and the two transmission shafts 17 pass through the multiple groups of diversion structures 5 on the left and right sides of the wastewater treatment tower 1, respectively, and the transmission shaft 17 is fixedly connected to the spiral plate 9 in the diversion structure 5; Among them, a plurality of slide grooves are opened on the outer wall of the auxiliary pipe 10, and the slide grooves are distributed in a ring shape around the outer wall of the auxiliary pipe 10 along the vertical direction. A plurality of sliding edges are arranged on the inner wall of the transmission ring 14, and the sliding edges are slidably installed in the slide grooves. The transmission shaft 17 passes through the bubble exhaust structure 6 and is rotatably connected to each other.

[0031] In detail, when wastewater flows through the auxiliary pipe 10, the wastewater will use the multiple fan blades 13 in the auxiliary pipe 10 to push the auxiliary pipe 10 to rotate. At this time, the auxiliary pipe 10 will drive the transmission wheel 15 and the transmission belt 16 to rotate through the transmission ring 14, thereby driving the two transmission shafts 17 to rotate, and the transmission shaft 17 will then drive the spiral plate 9 in the vertical cylinder 7 to rotate, so as to provide power for each group of diversion structures 5.

[0032] Based on the above embodiment, since the auxiliary pipe 10 and the guide bucket 11 rotate, the wastewater discharged from the uppermost guide structure 5 among the multiple guide structures 5 can flow horizontally to the position of the guide bucket 11, so that the water flow can fully flush the outer wall of the guide bucket 11.

[0033] Since the auxiliary pipe 10 and the guide bucket 11 need to vibrate in the vertical direction, it is necessary to use the structure of the slide groove and the sliding edge to realize the connection between the transmission ring 14 and the auxiliary pipe 10. When the auxiliary pipe 10 moves up and down, it slides relative to the transmission ring 14. When the auxiliary pipe 10 rotates, it rotates synchronously with the transmission ring 14.

[0034] Furthermore, the vibration structure includes a wave groove 18 opened on the outer wall of the water inlet pipe 2, the wave groove 18 is annular around the outer wall of the drainage pipe 2, and a plurality of guide columns 19 are slidably arranged in the wave groove 18, and the guide columns 19 are fixedly connected to the auxiliary pipe 10.

[0035] In detail, since the water inlet pipe 2 is supported by the fixed frame 25, when the auxiliary pipe 10 rotates relative to the water inlet pipe 2, the auxiliary pipe 10 will drive the guide column 19 to slide in the wave groove 18. Due to the structural characteristics of the wave groove 18, the guide column 19 can reciprocate in the vertical direction, thereby driving the auxiliary pipe 10 and the guide bucket 11 to vibrate back and forth in the vertical direction.

[0036] Furthermore, a bow plate 20 is slidably provided on the inner wall of the wastewater treatment tower 1, and a connecting ring 21 is rotatably sleeved on the outer wall of the auxiliary pipe 10. The connecting ring 21 and the bow plate 20 are fixedly connected by a connecting rod 22, and the connecting rod 22 is immersed in the water in the wastewater treatment tower 1.

[0037] In detail, when the auxiliary pipe 10 vibrates, it can drive the connecting ring 21, the connecting rod 22 and the bow plate 20 to vibrate synchronously. The bow plate 20 slides on the inner wall of the wastewater treatment tower 1. The vibration of the bow plate 20 and the connecting ring 21 can form two-way ripples on the water surface, thereby utilizing the ripples to make the scum on the water surface gather between the bow plate 20 and the connecting ring 21, thereby preventing the scum from being adsorbed and deposited on the inner wall of the wastewater treatment tower 1.

[0038] Based on the above embodiment, since the shape of the arch plate 20 is arch-shaped and the opening of the arch plate 20 faces the slag discharge channel 4, when the arch plate 20 and the connecting ring 21 vibrate, water waves will be transmitted toward the slag discharge channel 4, so that the ripples can be used to push the slag to the vicinity of the slag discharge channel 4, which is convenient for the discharge of the slag. Since the connecting rod 22 is submerged in water, the vibration of the connecting rod 22 can be avoided from interfering with the water surface.

[0039] Furthermore, the bubble exhaust structure 6 includes a plurality of long tubes 23 installed at the bottom of the inner wall of the wastewater treatment tower 1 , each long tube 23 is provided with a plurality of nozzles, and the plurality of long tubes 23 are connected through a multi-way tube 24 .

[0040] In detail, air can be pumped into the long tube 23 through the multi-way pipe 24 and discharged into the water in the wastewater treatment tower 1 through the nozzle on the long tube 23, thereby forming a large number of bubbles in the water. Of course, the supply of bubbles can also be achieved by dissolving air or other methods.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
