Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a municipal sewage temporary storage device for water conservancy projects. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. It is mainly water used in daily life. It contains a lot of organic matter and is relatively easy to treat. Among the water pollution caused by human production activities, industrial water pollution is the most serious. Agricultural pollution is mainly due to the loosening of the land surface caused by cultivation or land reclamation. When the soil and topography are not yet stable, rainfall causes a large amount of silt to flow into the water, increasing the suspended solids in the water.

[0003] Municipal sewage is a type of wastewater. In municipal sewage, food wastewater or certain industrial mixed wastewater can cause grease to solidify and clump at low temperatures, clogging the screens and pump inlets.

[0004] Therefore, this invention proposes a municipal sewage temporary storage device for water conservancy projects to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0005] In view of the above problems, the present invention provides a municipal sewage temporary storage device for water conservancy projects, which can effectively solve the problem that grease will solidify and clump in sewage at low temperatures in the prior art. To achieve the above objective, the embodiments of this application provide the following technical solutions:

[0006] This invention discloses a municipal sewage temporary storage device for water conservancy projects, including a mobile trolley. The top of the mobile trolley is equipped with a heating mechanism to facilitate sewage discharge. The heating mechanism is equipped with a swing mechanism to facilitate comprehensive heating of the sewage. The heating mechanism is also equipped with a stirring mechanism to ensure uniform heating of the sewage. The bottom of the heating mechanism is equipped with a ventilation mechanism to continuously heat the sewage.

[0007] The heating mechanism includes an inner barrel fixedly connected to the top of the mobile trolley, an outer barrel wrapped around the inner barrel, and the bottom of the outer barrel fixedly connected to the top of the mobile trolley. The top of the mobile trolley is also symmetrically provided with brackets, and each bracket has multiple flame nozzles on the side near the inner barrel.

[0008] Furthermore, the top of the mobile trolley is also horizontally rotatably connected to a support ring, which is located in the gap between the outer and inner barrels. The top of the support ring is fixedly connected to the bottom of the two brackets. Each bracket has an internal receiving cavity, which is connected to the flame nozzle.

[0009] Furthermore, a gear ring is coaxially fixedly connected to the inner side of the support ring, a servo motor is fixedly connected to the bottom of the moving trolley, and a gear is fixedly connected to the output end of the servo motor, the gear meshing with the gear ring.

[0010] Furthermore, the swing mechanism includes a connecting plate that is vertically slidably connected inside the receiving cavity. Multiple swing rods are rotatably connected to the side of the connecting plate. The middle part of each swing rod is rotatably connected to the side wall of the receiving cavity via a rotating shaft. A flame gun is fixedly connected to the end of the swing rod away from the connecting plate, and the flame gun is located at the flame nozzle. The bottom extension end of the connecting plate slides through the support ring and extends to the bottom of the support ring.

[0011] Furthermore, a roller is fixedly connected to the bottom extension end of the connecting plate, and a ring is fixedly connected to the top of the moving trolley. The top of the ring has grooves at equal angles, and the roller is tumblingly connected to the top of the ring and the grooves.

[0012] Furthermore, a return spring is fixedly connected to the top of the connecting plate, and the end of the return spring away from the connecting plate is fixedly connected to the inner top surface of the receiving cavity.

[0013] Furthermore, the agitation mechanism includes a horizontal bar fixedly connected to the top of two supports, a vertical bar fixedly connected to the bottom of the horizontal bar, and the vertical bar extending downward into the inner barrel.

[0014] Furthermore, multiple first blades are fixedly connected at equal intervals to the outside of the vertical rod, and the first blades are arranged horizontally and inclined. Multiple second blades are fixedly connected at equal intervals to the side of the vertical rod away from the first blades, and the second blades are arranged vertically and inclined.

[0015] Furthermore, the ventilation mechanism includes a housing fixedly connected to the bottom of the outer barrel, with one end of the housing extending to the outside of the outer barrel and the other end of the housing having an inclined air inlet. A fan for blowing air into the outer barrel is fixedly connected inside the housing.

[0016] Furthermore, a cover plate is rotatably connected to the outside of the outer casing, and the cover plate is arranged obliquely outside the air inlet.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This device is equipped with a heating mechanism. A support ring driven by a servo motor, gears and a gear ring is set between the inner and outer barrels. This ring drives the two side supports and their flame nozzles to rotate around the circumference of the inner barrel for heating. This avoids local overheating or dead zones caused by single-point fixed heating, and makes the outer wall of the inner barrel more fully heated. This prevents the grease in the sewage from solidifying and sticking to the inner wall in a low-temperature environment, and ensures that the sewage is discharged smoothly.

[0019] 2. This device is equipped with a swing mechanism. The rollers at the bottom of the support ring roll on a circular ring with equal-angled grooves. In conjunction with the return spring, the connecting plate is forced to slide up and down, thereby driving each swing rod to swing back and forth around the axis. This allows the flame gun to swing up and down at the flame nozzle, changing the circumferential single-line heating to vertical fan-shaped coverage, further expanding the heat exchange area and heating uniformity of the outer wall.

[0020] 3. This device is equipped with a stirring mechanism. The horizontal bar at the top of the support drives the vertical bar to extend into the inner tank and rotate. In conjunction with the first and second blades that are equidistantly and alternately arranged on the vertical bar, the internal liquid thermocline is broken and suspended solids and grease are prevented from settling, so that the sewage inside the inner tank is heated and flows evenly.

[0021] 4. This device is equipped with a ventilation mechanism. By setting a fan and an air inlet at the bottom of the outer barrel, air is continuously blown into the gap between the double-layer barrels to supplement sufficient oxygen, ensuring that the flame gun can burn and heat fully and continuously. The inclined cover plate hinged to the outside of the air inlet can not only open and close with the airflow, but also prevent external mud and sand impurities from flowing back in, thus improving the operational stability and safety during outdoor operations.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] The present invention will be further described below with reference to embodiments.

[0033] See Figures 1 to 7 This embodiment of a municipal sewage temporary storage device for a water conservancy project includes a mobile trolley 10. The top of the mobile trolley 10 is provided with a heating mechanism 20 to facilitate sewage discharge. The heating mechanism 20 is provided with a swing mechanism 30 to facilitate comprehensive heating of the sewage. The heating mechanism 20 is also provided with a stirring mechanism 40 to ensure uniform heating of the sewage. The bottom of the heating mechanism 20 is provided with a ventilation mechanism 50 to continuously heat the sewage.

[0034] See Figure 1 , Figure 2 , Figure 4 and Figure 7 The heating mechanism 20 includes an inner barrel 201 fixedly connected to the top of the mobile trolley 10. The inner barrel 201 is wrapped with an outer barrel 202, and the bottom of the outer barrel 202 is fixedly connected to the top of the mobile trolley 10. The top of the mobile trolley 10 is also symmetrically provided with brackets 205. Each bracket 205 has multiple flame nozzles 207 on the side near the inner barrel 201.

[0035] The top of the mobile trolley 10 is also horizontally rotatably connected to a support ring 208, which is located in the gap between the outer barrel 202 and the inner barrel 201. The top of the support ring 208 is fixedly connected to the bottom of two supports 205. Each support 205 has a receiving cavity 206 inside, and the receiving cavity 206 is connected to the flame nozzle 207. The inner ring of the rotating track of the support ring 208 is provided with a stationary annular air groove, which is connected to the external air source pipeline on the mobile trolley 10. The bottom surface of the support ring 208 has a dynamic pressure air inlet hole. The lower end of the dynamic pressure air inlet hole slides in close contact with the annular air groove, and the upper end is connected to the receiving cavity 206 that runs longitudinally through the support 205 through a pipeline. After the gas or heating medium enters the stationary annular air groove from the external pipeline, it is continuously introduced into the receiving cavity 206 through the dynamically connected dynamic pressure air inlet hole, thereby achieving a stable, entangle-free gas delivery when the support ring 208 continues to revolve.

[0036] A gear ring 203 is coaxially fixedly connected to the inner side of the support ring 208. A servo motor 204 is fixedly connected to the bottom of the mobile trolley 10. A gear 209 is fixedly connected to the output end of the servo motor 204. The gear 209 meshes with the gear ring 203.

[0037] In practical operation, when the municipal sewage temporary storage device at the water conservancy project site begins operation, the control system activates the servo motor 204 fixedly installed at the bottom of the mobile trolley 10. After receiving the electrical signal, the servo motor 204 outputs a preset speed and torque, driving the gear 209, which is coaxially fixedly connected to its output end, to rotate. The gear 209 maintains a meshing state with the gear ring 203, which is coaxially fixed to the inner wall of the support ring 208. The rotational power of the servo motor 204 is converted into a low-speed rotational torque of the support ring 208 through the transmission ratio. Driven by the meshing force of the gear ring 203, the support ring 208, located inside the concentric annular sandwich cavity of the outer barrel 202 and the inner barrel 201, moves. The top of the trolley 10 achieves circumferential horizontal rotation. Two brackets 205, fixedly welded to the symmetrical sides of the top of the support ring 208, move in a ring around the outer circumference of the inner barrel 201 in sync with the support ring 208. Gas or heating medium is introduced into the longitudinally penetrating receiving cavity 206 inside the bracket 205 through the rotary joint pipeline. The receiving cavity 206 evenly distributes the gaseous fuel and guides it to multiple nozzles 207 that are equidistantly opened along the vertical direction of the bracket 205. The flame heat flow is sprayed from each nozzle 207 onto the outer wall surface of the inner barrel 201. Since the bracket 205 is in a continuous revolution state, the sprayed flame spreads an all-round ring envelope heating along the entire outer cylindrical surface of the inner barrel 201. The multi-point flame nozzle 207, combined with the orbital motion, overcomes the defects of traditional single-point fixed heating methods that are prone to localized overheating or the formation of heating dead zones. It improves the heat coverage and heat flux uniformity of the outer wall of the inner tank 201, prevents the grease carried in municipal sewage from condensing and caking at the edge of the inner wall in a low-temperature environment, ensures the unobstructed sewage discharge channel, and guarantees that sewage can be discharged smoothly.

[0038] See Figure 1 , Figure 3 and Figure 6 The swing mechanism 30 includes a connecting plate 301 vertically slidably connected inside the receiving cavity 206. A plurality of swing rods 306 are rotatably connected to the side of the connecting plate 301. The middle part of each swing rod 306 is rotatably connected to the side wall of the receiving cavity 206 through a rotating shaft. A flame gun 307 is fixedly connected to the end of the swing rod 306 away from the connecting plate 301, and the flame gun 307 is located at the flame nozzle 207. The bottom extension end of the connecting plate 301 slides through the support ring 208, and the extension end of the connecting plate 301 extends to the bottom of the support ring 208.

[0039] A roller 303 is fixedly connected to the bottom extension end of the connecting plate 301, and a ring 304 is fixedly connected to the top of the moving trolley 10. The top of the ring 304 has a groove 305 at an equal angle, and the roller 303 is tumblingly connected to the top of the ring 304 and the groove 305.

[0040] A reset spring 302 is fixedly connected to the top of the connecting plate 301, and the end of the reset spring 302 away from the connecting plate 301 is fixedly connected to the inner top surface of the receiving cavity 206.

[0041] In actual operation, as the servo motor 204 drives the support ring 208 to rotate, the roller 303, which is slidably inserted through the bottom of the support ring 208 and fixedly connected, moves on the annular track on the top of the moving trolley 10. The track is composed of a circular ring 304 fixed to the top of the moving trolley 10, and the top of the circular ring 304 has multiple arc-shaped recessed grooves 305 evenly spaced at equal angles. When the roller 303 rolls along the horizontal upper surface of the circular ring 304, the connecting plate 301 remains in a high position. When the roller 303 rotates into the groove 305, the connecting plate 301... Driven by the continuous elastic downward pressure of the return spring 302 connected to the top, the connecting plate 301 slides rapidly downward along the vertical groove of the receiving cavity 206 inside the bracket 205. Then, the roller 303 rolls out of the inclined climbing section of the groove 305 as it rotates. Under the action of the mechanical lifting force of the slope, it overcomes the elastic resistance of the return spring 302 and drives the connecting plate 301 to slide upward and reset. Every time the support ring 208 rotates once, the roller 303 enters and exits the groove 305 multiple times, thereby causing the connecting plate 301 to generate high-frequency vertical up-and-down reciprocating mechanical motion in the receiving cavity 206. When the connecting plate 301 slides up and down inside the receiving cavity 206, the inner ends of the multiple swing rods 306 rotatably connected to its side wall simultaneously produce vertical displacement. Since the middle part of each swing rod 306 is rotatably connected to the fixed side wall of the receiving cavity 206 through a hinge shaft, a lever swing structure with the middle shaft as the fulcrum is formed. When the connecting plate 301 moves downward, the inner end of the swing rod 306 moves downward, forcing its outer end to generate an angular displacement and tilt upward around the middle shaft; conversely, when the connecting plate 301 is lifted upward by the ring 304, the inner end of the swing rod 306 moves upward, forcing its outer end to generate an angular displacement and tilt downward. The flame gun 307 fixedly connected to the outermost end of each swing rod 306 extends into each flame nozzle 207. As the swing arm 306 reciprocates in pitch and oscillation, the nozzle axis of the flame gun 307 continuously changes its elevation and depression angles in the vertical plane, causing the ejected flame column to sweep up and down at a wide angle within the trumpet-shaped guide groove of the flame nozzle 207. This adds a vertical, longitudinal fan-shaped dynamic oscillation to the existing horizontal circumferential rotation of the heat source, expanding the effective heat exchange area on the outer wall of the inner barrel 201, resulting in extremely rapid and uniform heating of the inner barrel 201 wall.

[0042] See Figure 1 , Figure 2 and Figure 4 The stirring mechanism 40 includes a horizontal bar 401 fixedly connected to the top of two supports 205, and a vertical bar 402 fixedly connected to the bottom of the horizontal bar 401, with the vertical bar 402 extending downward into the inner barrel 201.

[0043] Multiple first blades 403 are fixedly connected at equal intervals to the outside of the vertical rod 402, and the first blades 403 are arranged horizontally and inclined. Multiple second blades 404 are fixedly connected at equal intervals to the side of the vertical rod 402 away from the first blades 403, and the second blades 404 are arranged vertically and inclined.

[0044] In operation, when the heating mechanism 20 is running, the supports 205 on both sides revolve around the inner barrel 201, and the rigid crossbar 401 at the top of the two supports 205 rotates horizontally and coaxially accordingly. A vertical rod 402 is vertically fixed to the bottom center of the crossbar 401, and the vertical rod 402 extends downwards cantilevered into the deep interior of the inner barrel 201, rotating synchronously with the crossbar 401. By utilizing the outer heating supports 205 and the crossbar 401 to form a portal frame structure spanning the top of the inner barrel 201, the annular driving force outside the barrel is directly transferred to the rotational stirring power of the shaft core inside the barrel. This eliminates the need to open a dynamic sealing stirring shaft hole at the bottom of the inner barrel 201, reducing the risk of wear and leakage of the bottom sealing ring under the erosion of mud and sewage.

[0045] Multiple first blades 403, fixed to one side of the vertical rod 402 and arranged at equal intervals, rotate circumferentially with the vertical rod 402. Because the first blades 403 are arranged at a horizontally inclined angle, they generate a horizontal circumferential shear force and a radial centrifugal thrust on the sewage medium during rotation, forcing the sewage in each liquid layer inside the tank to diffuse and flush from the center towards the heated outer wall of the inner tank 201. On the other side of the vertical rod 402 away from the first blades 403, multiple second blades 404, arranged at a vertically inclined angle, are fixedly connected at equal intervals. During rotation, the vertical inclination angle of the second blades 404 generates an axial vertical lifting force and a longitudinal overturning force on the fluid, drawing up and pulling the heavy sewage and settled silt from the bottom of the inner tank 201, while simultaneously drawing the surface oil downwards.

[0046] See Figure 1 and Figure 3 The ventilation mechanism 50 includes a housing 501 fixedly connected to the bottom of the outer barrel 202, with one end of the housing 501 extending to the outside of the outer barrel 202 and the other end of the housing 501 having an inclined air inlet 503. A fan 502 for blowing air into the outer barrel 202 is fixedly connected inside the housing 501.

[0047] A cover plate 504 is rotatably connected to the outside of the outer casing 501, and the cover plate 504 is inclinedly arranged outside the air inlet 503. Multiple exhaust holes are evenly distributed around the top side wall of the outer barrel 202, and downward-sloping rainproof louvers are welded to the outside of the exhaust holes. Driven by the positive pressure of the bottom fan 502, the exhaust gas generated by combustion flows upward along the space between the inner and outer barrels, thoroughly flushing the outer wall of the inner barrel 201 to complete heat exchange, and finally exits the device through the exhaust holes at the top, forming a complete positive pressure combustion airflow circulation.

[0048] In operation, the outer casing 501 of the ventilation mechanism 50 is fixedly installed on the bottom outer wall of the outer barrel 202. One end of the air intake channel of the outer casing 501 extends outward and is exposed to the outside atmosphere, while the other end connects to the annular combustion chamber between the outer barrel 202 and the inner barrel 201. When the flamethrower 307 is ignited, the fan 502 installed inside the outer casing 501 is started and rotated under control, generating a negative pressure difference in the air intake channel. This draws in outside air through the inclined air inlet 503 and pressurizes it, blowing it into the interlayer space inside the outer barrel 202. By actively injecting oxygen-rich air into the sealed gap of the double-layer barrel by the fan 502, the disadvantage of oxygen deficiency inside the double-layer sealed structure is overcome, providing sufficient combustion oxygen for multiple flamethrowers 307 and ensuring complete combustion of fuel. A cover plate 504 is rotatably hinged to the outside of the outer casing 501 at the inclined air inlet 503. In its free state, the cover plate 504 is inclined and attached to the edge of the air inlet 503 of the outer casing 501 under the action of gravity. When the fan 502 operates, generating intake suction and airflow, the cover plate 504 rotates upward around the hinge axis to open the air intake passage. When the fan 502 stops or encounters strong winds, sandstorms, rain, snow, or splashing mud and water, the cover plate 504 quickly falls back into position under gravity and obliquely closes the air inlet 503. During equipment shutdown or relocation operations, it can form a mechanical barrier to prevent rainwater, dust, and impurities from the external environment from flowing back into the fan 502 or combustion chamber.

[0049] Working principle:

[0050] First, the fan 502 of the ventilation mechanism 50 is activated to open the cover plate 504, and combustion air is continuously blown into the interlayer through the air inlet 503. Then, the heating mechanism 20 ignites the flame gun 307. At the same time, the servo motor 204 drives the gear ring 203 and the support ring 208 to rotate through the gear 209, which drives the bracket 205 to perform circumferential heating along the inner barrel 201. During the rotation of the support ring 208, the roller 303 of the swing mechanism 30 rolls on the groove 305 of the ring 304. With the help of the return spring 302, the connecting plate 301 slides up and down, which drives the swing rod 306 and the flame gun 307 to swing up and down, realizing vertical fan-shaped sweeping heating. At the same time, the bracket 205 drives the vertical rod 402 of the stirring mechanism 40 to rotate synchronously in the inner barrel 201 through the horizontal bar 401. The horizontally inclined first blade 403 and the vertically inclined second blade 404 form a three-dimensional turbulence, which makes the sewage heat evenly and prevents the grease from caking and settling.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
