Description

Technical Field

[0001] The present invention belongs to the technical field of urban sewage treatment, and in particular relates to an urban domestic sewage treatment device. Background Art

[0002] Activities in cities often rely on the use of water. Wastewater is collected through sewer pipes. Direct discharge of wastewater will harm the environment. It is necessary to centrally treat the wastewater and discharge it after ensuring that it meets the requirements. Protecting the environment is also protecting ourselves.

[0003] Flocculants can absorb suspended matter in sewage and form flocculent particles, which sink as a whole to achieve solid-liquid separation and purify sewage. Different flocculants can be used for treatment according to different types of sewage;

[0004] Existing sewage treatment equipment has the following problems: 1) The treatment volume of urban sewage is large and the concentrated impurities are complex, making it difficult to quickly achieve solid-liquid separation during the treatment process; 2) When the filter belt filters solids in the sewage, the solids contain water and will stick to the filter belt, resulting in the filter belt being unable to normally transport the solids to the designated location, and at the same time greatly reducing the filtration effect; 3) The flocculation process of the chemical treatment takes a long time, which is difficult to meet the needs of large-scale sewage treatment. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide an urban domestic sewage treatment device, which filters the solid matter in the sewage through a filtering mechanism and transports it for separation, and then uses a sedimentation mechanism to adsorb and settle the suspended matter in the sewage, with a large treatment capacity and high efficiency.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] An urban domestic sewage treatment device comprises a filtering mechanism and a sedimentation mechanism, wherein the sedimentation mechanism is provided on one side of the filtering mechanism;

[0008] The filter mechanism includes a filter box, a screening mechanism, a supporting ramp, a supporting slide bar, a vibration mechanism, a first conveyor belt, a second conveyor belt, a filter belt, a convex plate, and a brushing mechanism, wherein one side of the top of the filter box is provided with several supporting ramps, one side of the supporting ramp is provided with several supporting slide bars, the supporting slide bar and the supporting ramp are sleeved together, the supporting slide bar and the bottom of the screening mechanism are fixedly connected, one end of the screening mechanism is provided with a vibration mechanism, the top of the filter box is provided with a first conveyor belt, both sides of the first conveyor belt are provided with enclosures, both ends of the first conveyor belt are fixed on the filter box, one side of the first conveyor belt is provided with a filter belt, a number of convex plates are evenly provided on the filter belt, the filter belt is fixed on the filter box, one side of the filter belt is provided with a second conveyor belt, both ends of the second conveyor belt are fixed on the filter box, enclosures are provided on both sides of the second conveyor belt, and one side of the second conveyor belt is provided with a brushing mechanism;

[0009] The sewage is sent to the screening mechanism to perform preliminary filtration, crushing and squeezing of solids in the sewage. At the same time, the vibration mechanism drives the screening mechanism and the supporting slide bar to slide back and forth on the supporting inclined rail. The water passes through the screening mechanism and flows into the filter box. The solids on the screening mechanism are sent to the first conveyor belt, and the first conveyor belt transfers the solids out. The sewage passes through the filter belt in the filter box and flows to the sedimentation mechanism. The filter belt further filters the solids in the sewage. At the same time, the rotation of the filter belt drives the rotation of the convex plate, and the convex plate drives the solids obliquely upward to the top of the filter belt. Since the filter belt is above the second conveyor belt, the solids will fall onto the second conveyor belt under the action of gravity. At the same time, the brushing mechanism brushes the solids adhered to the filter belt and the convex plate onto the second conveyor belt, and then transfers them out from the second conveyor belt. The enclosure prevents the solids on the first conveyor belt and the second conveyor belt from falling back into the filter box.

[0011] The sewage is sent to the screening mesh plate, and the vibration mechanism drives the vibration frame, screening mesh plate, and water squeezing mesh plate to shake back and forth, and the solids in the water are screened out through the screening mesh plate, and the remaining water passes through the screening mesh plate and flows into the filter box. The motor provides power for the rotation of the screw, and the screw drives the pusher frame and the connecting rail block to slide through the connecting block. The connecting rail block slides on the flat rail, and the pusher frame drives the pushing rotary plate and the pushing brush to move, and the pushing rotary plate and the pushing brush then push the solids on the screening mesh plate to the crushing roller. The front stopper provides reaction support for the pushing rotary plate to push the solids until the pushing rotary plate is pushed to the returning rubber block, and the returning rubber block pushes the pushing rotary plate, and the pushing rotary plate rotates on the pushing rack, causing the pushing brush to turn away from the screening mesh plate, and the screw reverses, and then the pushing rack, pushing rotary plate and pushing brush are returned to their original position until the pushing rotary plate is reset by the reset rubber block, and the above action is repeated to push the solids to the crushing roller, and the solids are pushed to the crushing roller through the guide blocks. The crushing roller is driven by the motor to provide power for the rotation of the crushing roller through the pulley and the belt.

The crushed solid falls onto the water squeezing screen and moves toward the water squeezing roller under the inertia of vibration. The motor provides power for the rotation of the water squeezing roller. The water squeezing roller squeezes the water on the crushed solid and falls into the filter box through the water squeezing screen. The solid then falls to the first conveyor belt.

The top of the support frame is fixedly connected to the fixed plate, one end of the fixed plate is fixedly connected to the top of the filter box, and the other end of the fixed plate is movably connected to the rotating wheel.

One group of adjusting rods is movably connected to the driving wheel, and the other group of adjusting rods is movably connected to the vibration frame, and the threads on the two groups of adjusting rods are in opposite directions.

[0013] The motor provides power for the rotating wheel to rotate on the fixed plate, and the rotating wheel in turn drives the driving wheel to rotate, and the driving wheel in turn drives the screening mechanism to swing back and forth through the adjusting rod and the threaded sleeve to achieve screening and filtration of solids in the sewage. Since the threads on the two sets of adjusting rods are in opposite directions, the threaded sleeve is rotated to adjust the relative position of the threaded sleeve and the adjusting rod, thereby adjusting the distance between the driving wheel and the screening mechanism, adjusting the shaking intensity, and adjusting the distance between the screening mechanism and the first conveyor belt.

[0015] The motor provides power for the rotation of the rotating rod, which in turn drives the ball head rod to rotate, and the ball head rod drives the swing sleeve to swing left and right on the fixed shaft through the control panel, thereby driving the swing brush to brush the solids on the filter belt and the convex plate down and fall to the second conveyor belt. The electric push rod provides power for the positioning plate to slide on the filter box, and the positioning plate drives the fixed frame to move, thereby driving the fixed shaft and the swing brush to move, adjusting the relative position between the swing brush and the filter belt to ensure the brushing effect of the swing brush.

[0016] The sedimentation mechanism includes a sedimentation box, a feeding hopper, an auger feeding pipe, a water feeding pipe, a stirring mechanism, a flow stabilizing plate, a sedimentation tank, a water outlet pipe, and a baffle.

Several flow stabilizing plates are provided on the inside of the sedimentation box. A stirring mechanism is provided on one side of the flow stabilizing plate. A sedimentation tank is provided on the other side of the flow stabilizing plate. A baffle is provided on one side of the sedimentation tank.

[0017] The sewage filtered by the filter box enters the sedimentation tank, and the flocculant is fed into the auger feed pipe through the feeding hopper. Then, water is fed into the auger feed pipe through the water adding pipe to mix with the flocculant to form a slurry. The slurry is then fed into the sedimentation tank through the auger feed pipe to mix with the sewage. The floating objects in the sewage are adsorbed and settled. At the same time, the stirring mechanism stirs and mixes the sewage and flocculant. The mixed sewage passes through the flow stabilizing plate, and the particles formed by the flocculant adsorption settle into the sedimentation tank.

[0019] The motor provides power for the rotation of the cam, and the cam drives the rack to slide back and forth in the sleeve block through the driving rod, thereby driving the gear to rotate back and forth, and then driving the rotating plate, the triangular rod and the horizontal stirring rod to rotate back and forth. When the rotating plate rotates, the guide block slides on the guide round rod, and the spring on one side is squeezed by the guide block. At the same time, the spring provides elastic support for the guide block, which drives the round connecting rod, the spring stirring plate and the T-shaped stirring rod to rotate. The rotation speed of the spring stirring plate is lower than that of the rotating plate; when the rotating plate rotates in the opposite direction, the spring on one side stretches quickly, and the spring on the other side is squeezed by the guide block. Until the guide block gradually slides in the opposite direction on the guide round rod, and then the round connecting rod, the spring stirring plate and the T-shaped stirring rod are driven by the guide block, first gradually slow down and then rotate in the opposite direction, and then the rotation speeds of the triangular rod, the horizontal stirring rod and the T-shaped stirring rod are different, forming two different stirring speeds, making the stirring more uniform. At the same time, there is a time difference when reversing the rotation. When stirring the water body, gas is injected into the flotation disk through the ventilation pipe at the same time, and the flotation disk sprays bubbles into the sewage. The bubbles absorb and drive the floating objects in the water to float up, and at the same time, they are stirred and mixed with the flocculant and sewage.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1) The motor provides power for the rotation of the rotating plate, which in turn drives the ball rod to rotate. The ball rod then drives the swing sleeve to swing left and right on the fixed shaft through the control panel, thereby driving the swing brush to brush the solids on the filter belt and the convex plate down and drop them to the second conveyor belt, preventing solids from adhering to the filter belt, ensuring the filtering and transportation effect of the filter belt, and preventing the filter belt from being blocked and affecting the filtration volume. The electric push rod provides power for the positioning plate to slide on the filter box, which in turn drives the fixed frame to move, thereby driving the fixed shaft and the swing brush to move, adjusting the relative position between the swing brush and the filter belt, and adjusting the position according to the wear of the swing brush to ensure the brushing effect of the swing brush;

[0022] 2) When the rotating plate rotates, the guide block slides on the guide rod, and the spring on one side is squeezed by the guide block. At the same time, the spring provides elastic support for the guide block to drive the round connecting rod, the spring stirring plate and the T-shaped stirring rod to rotate. The rotation speed of the spring stirring plate is lower than that of the rotating plate; when the rotating plate rotates in the opposite direction, the spring on one side stretches quickly, and the spring on the other side is squeezed by the guide block until the guide block gradually slides in the opposite direction on the guide round rod, and then the round connecting rod, the spring stirring plate and the T-shaped stirring rod are driven by the guide block, first gradually slow down and then rotate in the opposite direction, and then the triangular rod and the horizontal stirring rod form a different rotation speed from the T-shaped stirring rod, and there is a time difference when reversing the rotation. When stirring the water body, two water flow speeds are formed, which improves the mixing effect of the sewage and flocculant, and prevents large vortices in the water, so as to avoid causing large-scale flow of water to impact the sedimentation tank. At the same time, gas is injected into the flotation disk through the vent pipe, and the flotation disk sprays bubbles into the sewage. The bubble adsorption drives the floating objects in the water to float up, and at the same time stirs and mixes with the flocculant and sewage, thereby increasing the adsorption effect of flocculation.

[0046] An urban domestic sewage treatment device, the working process is as follows:

[0047] The sewage is sent to the screening mesh plate, and at the same time, the vibration mechanism drives the vibration frame and the supporting slide bar to swing back and forth on the supporting inclined rail, thereby driving the screening mesh plate and the water squeezing mesh plate to swing back and forth, and the solids in the water are screened out through the screening mesh plate, and the remaining water passes through the screening mesh plate and flows into the filter box. The motor provides power for the rotation of the screw, and the screw drives the pusher frame and the rail block to slide through the connecting block. The rail block slides on the flat rail, and the pusher frame drives the pusher turn plate and the pusher brush to move. The pusher turn plate and the pusher brush then push the solids on the screening mesh plate to the crushing roller. The front block provides reaction support for the pusher turn plate to push the solids until the pusher turn plate is pushed to the return rubber block, and the return rubber block pushes the pusher turn plate, and the pusher turn plate rotates on the pusher frame. , causing the pushing brush to turn away from the screening mesh plate, the lead screw to reverse, and then the pushing frame, the pushing rotating plate and the pushing brush belt to return to their original positions until the pushing rotating plate is pushed back to its original position by the reset rubber block, and the above actions are repeated to push the solids to the crushing roller, and the solids are pushed to the crushing roller through the guide blocks, and then the motor provides power for the rotation of the crushing roller through the pulley and the belt. The crushing roller rotates synchronously driven by the synchronous gear, and the crushing roller rotates to squeeze and crush the fed solids. The crushed solids fall onto the water squeezing mesh plate and move toward the water squeezing roller under the action of vibration inertia. The motor provides power for the rotation of the water squeezing roller, and the water squeezing roller squeezes out the water on the crushed solids, and the solids fall into the filter box through the water squeezing mesh plate, and then fall to the first conveyor belt;

[0048] The first conveyor belt transfers the solids out, and the sewage passes through the filter belt in the filter box and flows to the sedimentation mechanism. The filter belt further filters the solids in the sewage. At the same time, the rotation of the filter belt drives the convex plate to rotate, and the convex plate drives the solids to be transported obliquely upward to the top of the filter belt. Since the filter belt is above the second conveyor belt, the solids will fall onto the second conveyor belt under the action of gravity. The motor provides power for the rotation of the rotating rod, and the rotating rod drives the ball head rod to rotate. The ball head rod drives the swing sleeve to swing left and right on the fixed shaft through the control panel, thereby driving the swing brush to brush off the solids on the filter belt and the convex plate and drop them to the second conveyor belt, and then be transferred out by the second conveyor belt;

[0049] The sewage after being filtered by the filter box enters the sedimentation tank, and the flocculant is fed into the auger feed pipe through the feeding hopper, and then the water is fed into the auger feed pipe through the water feeding pipe to mix with the flocculant to form a slurry, and then the auger feed pipe is fed into the sedimentation tank to mix with the sewage to adsorb and settle the floating objects in the sewage. The motor provides power for the rotation of the cam, and the cam drives the rack to slide back and forth in the sleeve block through the driving rod, thereby driving the gear to rotate back and forth, and then driving the rotating plate, triangular rod and horizontal stirring rod to rotate back and forth. When the rotating plate rotates, the guide block slides on the guide round rod, and one side of the spring is squeezed by the guide block. At the same time, the spring provides elastic support for the guide block, and the round connecting rod, the spring stirring plate and the T-shaped stirring rod are driven to rotate through the guide block. The rotation speed of the spring stirring plate is lower than that of the rotating plate; when the rotating plate rotates in the opposite direction, one side The spring on one side stretches quickly, and the spring on the other side is squeezed by the guide block until the guide block gradually slides in the opposite direction on the guide round rod, and then the round connecting rod, the spring stirring plate and the T-shaped stirring rod are driven by the guide block, first gradually slow down and then rotate in the opposite direction, so that the rotation speeds of the triangular rod, the horizontal stirring rod and the T-shaped stirring rod are different, and there is a time difference when reversing the rotation. When stirring the water body, gas is injected into the flotation disk through the vent pipe at the same time, and the flotation disk sprays bubbles into the sewage. The bubble absorption drives the floating objects in the water to float up, and at the same time, it is stirred and mixed with the flocculant and sewage. The mixed sewage passes through the flow stabilizing plate and the particles formed by the flocculant absorption settle into the sedimentation tank. The clarified water above passes over the baffle and is discharged from the outlet pipe. The flow stabilizing plate blocks the stirred and shaking water to prevent the impact on the sedimentation tank.
