Description

Technical Field

[0001] This invention relates to the field of automated processing equipment technology, specifically to an automated device for efficiently treating sludge and wastewater. Background Technology

[0002] Wastewater and sludge treatment equipment is used to separate sludge from water for further treatment or discharge of treated water. Sludge is a solid waste generated during wastewater treatment; if not treated in a timely manner, it will cause incalculable harm to the environment and human health. Furthermore, sludge treatment can also adversely affect wastewater treatment facilities and the surrounding environment; therefore, timely separation and treatment are essential.

[0003] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Solid-liquid separation is generally used in wastewater treatment, prioritizing the separation of water and sludge. The separated sludge is then collected or transported, while the wastewater requires secondary purification before it can be used. When an automated process is activated, automated devices are needed to treat the wastewater.

[0004] Therefore, the existing technology, patent CN108585251B, discloses a method using a single motor as a power source, with multiple return channels installed at the sewage source. A pair of sewage treatment devices are mounted on the motor drive shaft, each containing multiple treatment screens. These screens rotate above the return channels, obstructing the water flow and causing solid-liquid separation within the channels. This method relies entirely on the motor's output frequency, which presents several problems: when the motor rotates slowly to ensure that dirt on the treatment screens flows into the collection box and avoids centrifugal force during rotation, the dirt remains stuck on the screens. However, this method is not very effective. It's possible that the inclined planes between adjacent treatment screens are not properly aligned, preventing water flow from being blocked and causing contamination of subsequent water sources. This necessitates increasing the rotation speed so that the dirt on the treatment screens flows into the collection box as they rotate. However, this requires perfect alignment between adjacent treatment screens, resulting in a short processing time for each screen. The centrifugal force generated also prevents the screen from completely removing the dirt, leaving some dirt stuck on it. Over time, this dirt can become trapped on the screen, leading to reduced filtration efficiency. To address this, we propose an automated device for efficiently treating sludge and wastewater. Summary of the Invention

[0005] The purpose of this invention is to provide an automated device for efficiently treating sludge and wastewater, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated device for efficiently treating sludge and wastewater, comprising a housing, a central plate installed in the middle of the housing, a separation plate installed above the central plate, a spiral line installed on the top of the separation plate, a drive device for rotating the separation plate installed below the central plate, and a cleaning assembly for cleaning dirt from the surface of the separation plate installed on one side of the housing; the cleaning assembly includes a fixing groove on the housing, a slider movable inside the fixing groove, a spring connected to the slider, a connecting plate at one end of the spring, a stop plate fixed to one side of the connecting plate, a contact piece threadedly connected to the bottom of the connecting plate, and a shovel head contacting the bottom of the stop plate and the top of the separation plate; a sliding cavity is opened at the top of the fixing groove, and a pair of limiting blocks are opened on both sides of the top of the fixing groove near the sliding cavity, and the slider is fixed together with the limiting blocks by a pin; a connecting sleeve is installed at the bottom of the fixing groove and fixed to the housing; a drawer is installed at the bottom of the fixing groove on one side of the housing.

[0007] Preferably, the drive device includes a large gear wheel located on one side of the bottom of the central plate, a small gear wheel concentric with the large gear wheel, a first gear located at the bottom of the housing and meshing with the large gear wheel, a second gear located at the top of the first gear and meshing with the small gear wheel, a third gear located at the top of the second gear, and a fourth gear located at the top of the third gear. The third gear meshes with the small gear wheel and rotates at the same speed and in the opposite direction to the second gear. The fourth gear meshes with the large gear wheel.

[0008] Preferably, a central plate is installed in the middle of the casing, a receiving plate is coaxially connected to the fourth gear, a processing plate is coaxially connected to the third gear, a limit line is installed on the casing near the top of the processing plate, and the second gear drive shaft is connected to the separation plate. A motor slot is installed on the casing near the large gear wheel, and the motor in the motor slot is connected to the large gear wheel. Multiple water outlet holes are equidistantly opened on the top of the filter tank of the casing, and water outlet pipes are installed on each water outlet hole.

[0009] Preferably, both sides of the housing are equipped with adsorption components for further treatment of wastewater after adsorption of solid-liquid separation. The adsorption components include filter tanks inclined on both sides of the housing, rotating rods fixed at both ends to the inner ring of the filter tanks by rotating shafts, spiral blades sleeved on the outer ring of the rotating rods, and multiple filter elements filled in the inner ring of the rotating rods.

[0010] The treated wastewater is discharged through the water outlet holes on both sides of the casing, and the water flows into the filter tank through the outlet pipe. Because the filter tank is placed at an angle, the water falls at different positions. The water at the higher position will drive the spiral blades to rotate according to the spiral principle. When the spiral blades are in motion, the water at the lower level will pass through the opening on the rotating rod, so that the filter elements located in the inner ring of the rotating rod can all come into contact with the wastewater, further improving the purification effect of filtering impurities.

[0011] Preferably, the casing is equipped with a liquid flow rate acceleration component for increasing the sewage inflow at the top near the separation plate. The liquid flow rate acceleration component includes a first rotating impeller located at the top of the casing and coaxially connected to the first gear, a second rotating impeller coaxially connected to the first gear and located at the bottom of the first rotating impeller, a first fixed wheel located on the casing and between the two first rotating impellers, and a second fixed wheel located at the bottom of the second rotating impeller.

[0012] More preferably, the blades of the first rotating impeller and the second rotating impeller have the same tilt direction, the blades of the first fixed wheel and the second fixed wheel have the same tilt direction, and the blades of the first rotating impeller and the first fixed wheel have opposite tilt directions.

[0013] When the external pipe is connected to the top of the casing, in order to improve the absorption effect of sewage, both the first and second fixed impellers are fixed to the casing. When sewage is above the first rotating impeller, the motor starts and the first and second rotating impellers rotate synchronously. The first rotating impeller and the first fixed impeller are staggered between each pair of impellers. Therefore, when the water flows through, the first rotating impeller cuts the water flow and enters the top of the first fixed impeller. Because the water flow generates thrust at the first rotating impeller, it will accelerate downward after contacting the top of the first fixed impeller. This process is repeated to efficiently treat the sewage.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The present invention uses an arched design of the separation plate to facilitate the flow of sludge and sewage to the edge due to centrifugal force when cleaning sludge and sewage, which makes it easy to spread the sludge and sewage horizontally. After the separation plate rotates, the sludge is positioned between the spiral lines by the limiting effect of the spiral lines. After the contact piece contacts the spiral lines, the fixing groove automatically descends, which makes it easy for the shovel head to fall into the separation plate. When the separation plate rotates a few times, the contact piece and the spiral lines separate, and the spring rebound force shakes the dirt into the drawer, which helps to improve the cleaning of the separation plate and facilitates the increase of the amount of sewage and sludge that the separation plate can handle.

[0016] (2) The present invention, through the design of the blade tilt direction, allows water to flow down quickly, which can efficiently treat drainage. At the same time, the blades effectively separate sewage and sludge, so that the sewage entering the adsorption component has less sludge content, thus the adsorption component can effectively simplify sewage and have a longer service life.

[0017] (3) The present invention controls different gears to rotate in different directions by a single motor, and then further controls the separation plate, the treatment plate and the receiving plate by the gears, so that they are in different rotation directions and cross each other, so that the sewage and sludge are better dispersed and separated, and the sewage treatment effect of the device is further improved.

Detailed Implementation

[0027] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8This invention provides a technical solution: an automated device for efficiently treating sludge and wastewater, comprising a housing 1, a central plate installed in the middle of the housing 1, a separation plate 7 installed above the central plate, a spiral line 8 installed on the top of the separation plate 7, a drive device for rotating the separation plate 7 installed below the central plate, and a cleaning component 3 for cleaning the surface of the separation plate 7 installed on one side of the housing 1; the cleaning component 3 includes a fixing groove 19 on the housing 1, a slider 21 movable inside the fixing groove 19, and a spring 22 connected to the slider 21. A connecting plate 23 is located at one end of the spring 22, a stop plate 24 is fixed to one side of the connecting plate 23, a contact piece 25 is threadedly connected to the bottom of the connecting plate 23, and a shovel head 26 is located at the bottom of the stop plate 24 and in contact with the top of the separation plate 7. A sliding cavity is opened at the top of the fixing groove 19, and a pair of limiting blocks 20 are opened on both sides of the top of the fixing groove 19 near the sliding cavity. The slider 21 is fixed together with the limiting blocks 20 by a pin. A connecting sleeve is installed at the bottom of the fixing groove 19 and fixed to the housing 1. A drawer 5 is installed on one side of the housing 1 at the bottom of the fixing groove 19.

[0029] Example 1: In wastewater treatment, wastewater can be introduced from the source through a pipe to the top of the casing 1. During the wastewater transport process, the flow rate of the wastewater inside the pipe can be controlled so that the wastewater flows onto the separation plate 7. In practice, the operator can choose between a mesh or plate-shaped separation plate 7 based on the actual situation (also based on cost). Generally speaking, mesh separation has a better solid-liquid separation effect, but the mesh is filamentous and the sludge may contain ribbons that can easily clog the holes. Plate separation is slower and less prone to clogging. Then, the drive device is powered to make the separation plate 7 rotate. During the rotation of the separation plate 7, the wastewater and sludge can be separated. However, as a result, the sludge on the separation plate 7 will gradually clog the holes over time, which is not conducive to the treatment of sludge and wastewater. Therefore, in this solution, a spiral line 8 is installed on the separation plate 7. The length of the shovel head 26 is equal to the spiral pitch of the spiral line 8. The middle of the separation plate 7 is arched and its surface contacts the bottom of the shovel head 26. The contact piece 25 and the shovel head 26 are in contact with the spiral line 8. As the shovel head 26 slides on the separating plate 7, the contact piece 25 slides on the contact spiral line 8 to ensure that the shovel head 26 does not derail. In implementation, the shovel head 26 is fixed together with the stop plate 24, which is fixedly connected to the spring 22. The spring 22 is fixed to the slider 21, which ensures that the shovel head 26 can only remain stationary within the pitch of the spiral line 8 (because the bottom inclined surface of the shovel head 26 abuts against the spiral line 8, and the contact piece 25 abuts against the spiral line 8, so that the shovel head 26 will not move). Then, after the separating plate 7 rotates a few times (designed according to the actual situation), the shovel head 26, following the spiral line 8, enters the center of the separating plate 7 due to the continuous output of tension from the spring 22. During this process, the shovel head 26 removes the sludge along the trajectory of the spiral line 8 on the separating plate 7 and shovels the sludge above the shovel head 26. The cleaning process is temporarily completed. When the shovel head 26 is located at the center of the separation plate 7, that is, when the shovel head 26 has completed its journey along the spiral line 8, the spring 22 pulls the stop plate 24, contact piece 25, and shovel head 26 back to their original positions due to the constraint of the spiral line 8. Since the spring 22's reset is rapid and generates a rebound vibration, this provides a sufficient vibration source for the shovel head 26 during the reset process, causing the sludge at its top to be collected inside the drawer 5 through the rebound vibration. When the shovel head 26 needs to be used again, the spring 22 causes the contact piece 25 to contact the spiral line 8 during the rebound process. After contacting the spiral line 8, the entire assembly will descend, causing the shovel head 26 and the spiral line 8 to align, allowing for the next cleaning operation. The filtered water will continue to the next layer for further processing.

[0030] The arched design of the separation plate 7 facilitates the flow of sludge and sewage to the edge due to centrifugal force during cleaning, making it easier to spread the sludge and sewage horizontally. After the separation plate 7 rotates, the spiral line 8 limits the sludge, keeping it within the spiral pitch of the spiral line 8. After the contact piece 25 contacts the spiral line 8, the fixing groove 19 automatically descends, allowing the shovel head 26 to fall onto the separation plate 7. After the separation plate 7 rotates a few times, the contact piece 25 separates from the spiral line 8, and the rebound force of the spring 22 shakes the dirt and grime into the drawer 5, which helps to improve the cleanliness of the separation plate 7 and increases the amount of sewage and sludge that the separation plate 7 can handle.

[0031] The drive device includes a large-toothed wheel 12 located on one side of the bottom of the central plate, a small-toothed wheel 13 on the large-toothed wheel 12 with the same center, a first gear 14 located at the bottom of the housing 1 and meshing with the large-toothed wheel 12, a second gear 15 located on the top of the first gear 14 and meshing with the small-toothed wheel 13, a third gear 16 located on the top of the second gear 15, and a fourth gear 17 located on the top of the third gear 16. The third gear 16 meshes with the small-toothed wheel 13 and rotates in the opposite direction at the same speed as the second gear 15. The fourth gear 17 meshes with the large-toothed wheel 12.

[0032] Depend on Figures 1-6 It is known that in this scheme, multiple gears are arranged vertically, and each gear can rotate independently without interfering with the operation of other gears.

[0033] A central plate is installed in the middle of the housing 1. The fourth gear 17 is coaxially connected to the receiving plate 11, and the third gear 16 is coaxially connected to the processing plate 9. Limiting lines 10 are installed on the housing 1 near the top of the processing plate 9. The transmission shaft of the second gear 15 is connected to the separation plate 7. A motor slot 18 is installed on the housing 1 near the large gear wheel 12. The motor in the motor slot 18 is connected to the large gear wheel 12. Multiple water outlet holes are equidistantly opened on the top of the filter tank 401 of the housing 1, and each water outlet hole is equipped with a water outlet pipe 6. The central plate arches towards the bottom center of the receiving plate 11.

[0034] Among them, by Figure 6It is known that a motor is installed inside the motor slot 18. After powering it, the second gear 15 drives the separation plate 7 to rotate, the third gear 16 drives the processing plate 9 to rotate, and the fourth gear 17 drives the receiving plate 11 to rotate. The four gears are of the same type. The rotation direction of the separation plate 7 is opposite to that of the processing plate 9 and the receiving plate 11. Since the fourth gear 17 meshes with the large gear wheel 12, which is on the outer ring of the small gear wheel 13, the fourth gear 17 rotates at a relatively fast speed. Therefore, after the sewage is separated on the limit line 10, it flows along the processing plate 9 to the receiving plate 11. The rotation speed of the receiving plate 11 is faster than that of the processing plate 9, so that the sewage on the receiving plate 11 is centrifuged again by rotation and flows to the central plate in the middle of the casing 1. Then it is discharged through the water outlet holes on the side plates of the casing 1.

[0035] Both sides of the housing 1 are equipped with adsorption components 4 for further treatment of wastewater after adsorption of solid-liquid separation. The adsorption components 4 include filter tanks 401 inclined on both sides of the housing 1, rotating rods 403 fixed at both ends to the inner ring of the filter tanks 401 by rotating shafts, spiral blades 402 sleeved on the outer ring of the rotating rods 403, and multiple filter elements 404 filled in the inner ring of the rotating rods 403.

[0036] The treated wastewater is discharged through the water outlet holes on both sides of the casing 1, and the water outlet pipe 6 flows into the filter tank 401. Because the filter tank 401 is placed at an angle, the water flow is not uniform. The water flow at the higher position will drive the spiral blade 402 to rotate according to the spiral principle. When the water flow is on the spiral blade 402, the water flow at the lower liquid level will pass through the opening on the rotating rod 403, so that the filter element 404 located in the inner ring of the rotating rod 403 can all come into contact with the wastewater, further improving the purification effect of filtering impurities.

[0037] The housing 1 is equipped with a liquid flow rate acceleration component 2 for increasing the sewage inflow at the top near the separation plate 7. The liquid flow rate acceleration component 2 includes a first rotating impeller 201 located at the top of the housing 1 and coaxially connected with the first gear 14, a second rotating impeller 203 coaxially connected with the first gear 14 and located at the bottom of the first rotating impeller 201, a first fixed wheel 202 located on the housing 1 and between the two first rotating impellers 201, and a second fixed wheel 204 located at the bottom of the second rotating impeller 203.

[0038] Example 2: When connecting the external pipe to the top of the casing 1, in order to improve the absorption effect of sewage, both the first fixed wheel 202 and the second fixed wheel 204 are fixed to the casing 1. When sewage is above the first rotating impeller 201, the motor starts, and the first rotating impeller 201 and the second rotating impeller 203 rotate synchronously. Figure 4It can be seen that the first rotating impeller 201 and the first fixed impeller 202 are staggered between each pair of impellers. The blades of the first rotating impeller 201 and the second rotating impeller 203 have the same tilt direction, and the blades of the first fixed impeller 202 and the second fixed impeller 204 have the same tilt direction. The blades of the first rotating impeller 201 and the first fixed impeller 202 have opposite tilt directions. Therefore, when water flows through, the first rotating impeller 201 cuts the water flow and it enters the top of the first fixed impeller 202. Because the water flow generates thrust at the first rotating impeller 201, it accelerates and flows downward after contacting the top of the first fixed impeller 202. This reciprocating motion efficiently processes the drainage.
