Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automated control device for sludge discharge. Background Art

[0002] Sludge discharge is a critical operation in wastewater treatment. In activated sludge biological treatment systems, new activated sludge is generated daily as wastewater enters, leading to an increase in the total sludge volume within the system. Automated control of sludge discharge can maintain a near-balanced total sludge volume within the system, which has a greater impact than other operations. For example, it can alter the types and growth rates of microorganisms in the activated sludge, its oxygen demand, and improve its settling properties, thereby changing the overall function of the system.

[0003] However, when existing devices achieve automated control of sludge discharge, sludge accumulation in certain locations within the sedimentation tank can prevent timely discharge, leading to excessive wastewater discharge.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed an automated control device for sludge discharge. Utility Model Content

[0005] The purpose of this invention is to provide an automated control device for sludge discharge to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated sludge discharge control device, comprising a sedimentation tank and a moving component. A sludge tank is located on the right side of the sedimentation tank. The moving component is located on the top of the sedimentation tank and includes a support frame, a servo motor, a lead screw, a lead screw nut, and a mounting base. A servo motor is installed on the left side of the support frame, and the output end of the servo motor is connected to the lead screw. A lead screw nut is connected to the outside of the lead screw, and a mounting base is located at the bottom of the lead screw nut. An ultrasonic sludge level gauge is installed on the bottom left side of the mounting base. A valve body is installed on the upper right side of the sludge tank, and a cylinder is installed inside the valve body. A travel plate is installed at the output end of the cylinder, and a valve plate is connected to the lower left side of the travel plate. An air blowing pipe is connected to the output end of the valve body, and a folded corrugated pipe is connected to the other end of the air blowing pipe. A flared pipe is installed at the end of the folded corrugated pipe away from the air blowing pipe. A second air blowing pipe is connected to the input end of the valve body. A sludge discharge pump is installed on the lower left side of the sedimentation tank.

[0007] Furthermore, the moving component also includes a timing pulley and a timing belt, and the timing pulley is sleeved on the outer right side of the lead screw, with the timing belt connected to the outside of the timing pulley.

[0008] Furthermore, the moving component also includes a second synchronous pulley and a second lead screw, with the second synchronous pulley passing through the middle of the synchronous belt and the second lead screw passing through the middle of the second synchronous pulley.

[0009] Furthermore, both ends of the second lead screw are rotatably connected to the support frame, and a lead screw nut is also connected to the outside of the second lead screw.

[0010] Furthermore, lead screw one and lead screw two are parallel to each other, and lead screw one and lead screw two rotate in the same direction.

[0011] Furthermore, the flared pipe extends through the opening on the surface of the mounting base, and the air blowing pipe, the folded corrugated pipe, the flared pipe, and the sedimentation tank are interconnected.

[0012] Furthermore, the travel plate and the valve plate are perpendicular to each other, and the valve plate is disposed inside the valve body.

[0013] This utility model provides an automated control device for sludge discharge, which has the following beneficial effects:

[0014] 1. The servo motor of this utility model drives the lead screw and the synchronous pulley to rotate. The synchronous belt and the synchronous pulleys 1 and 2 transmit power to make the lead screw rotate synchronously. This allows the mounting base and the ultrasonic sludge level gauge to move horizontally along the lead screw and the lead screw nut, thereby detecting the sludge level at different positions in the sedimentation tank and ensuring the accuracy of the sludge discharge.

[0015] 2. The air blowing pipe of this utility model is connected to an external air source. Since the output end of the flared pipe is higher than the input end of the sludge pump, the gas has a strong disturbing effect on the sludge, which can loosen the sludge located in the lower part of the sedimentation tank, thereby improving the fluidity of the sludge, preventing the sludge from accumulating in dead corners, and facilitating discharge.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 As shown, an automated sludge discharge control device includes a sedimentation tank 1 and a moving component 3. A sludge tank 2 is located on the right side of the sedimentation tank 1. The moving component 3 is located on top of the sedimentation tank 1 and includes a support frame 301, a servo motor 302, a lead screw 303, a lead screw nut 304, and a mounting base 309. The servo motor 302 is mounted on the left side of the support frame 301, and the output end of the servo motor 302 is connected to the lead screw 303. The lead screw nut 304 is connected to the outside of the lead screw 303, and the mounting base 309 is located at the bottom of the lead screw nut 304. An ultrasonic sludge level gauge 4 is mounted on the bottom left side of the mounting base 309. 3 also includes a timing pulley 305 and a timing belt 306, and the timing pulley 305 is sleeved on the outer right side of the lead screw 303. The timing belt 306 is connected to the outside of the timing pulley 305. The moving component 3 also includes a timing pulley 307 and a lead screw 308, and the timing pulley 307 is inserted through the middle of the timing belt 306. The lead screw 308 is inserted through the middle of the timing pulley 307. The two ends of the lead screw 308 are rotatably connected to the support frame 301, and the lead screw nut 304 is also connected to the outside of the lead screw 308. The lead screw 303 and the lead screw 308 are parallel to each other, and the rotation directions of the lead screw 303 and the lead screw 308 are the same.

[0022] The specific operation is as follows: the servo motor 302 drives the lead screw 303 and the synchronous pulley 305 to rotate. The synchronous belt 306 transmits power through the meshing between the synchronous pulley 305 and the synchronous pulley 307, so that the lead screw 303 and the ultrasonic sludge level gauge 4 rotate synchronously. This allows the mounting base 309 and the ultrasonic sludge level gauge 4 to move horizontally along the lead screw nut 304 along the lead screw 303 and the ultrasonic sludge level gauge 308, thereby detecting the sludge level at different locations in the sedimentation tank 1 and ensuring the accuracy of the sludge discharge.

[0023] like Figure 1 and Figure 3As shown, a valve body 5 is installed on the upper right side of the sludge tank 2, and a cylinder 6 is installed inside the valve body 5. A travel plate 7 is installed at the output end of the cylinder 6. A valve plate 8 is connected to the lower left side of the travel plate 7. An air blowing pipe 9 is connected to the output end of the valve body 5. A folded corrugated pipe 10 is connected to the other end of the air blowing pipe 9. A flared pipe 12 is installed at the end of the folded corrugated pipe 10 away from the air blowing pipe 9. An air blowing pipe 11 is connected to the input end of the valve body 5. A sludge discharge pump 13 is installed on the lower left side of the sedimentation tank 1. The flared pipe 12 passes through the opening on the surface of the mounting base 309. The air blowing pipe 9, the folded corrugated pipe 10, the flared pipe 12 and the sedimentation tank 1 are interconnected. The travel plate 7 and the valve plate 8 are perpendicular to each other. The valve plate 8 is located inside the valve body 5.

[0024] The specific operation is as follows: the air blowing pipe 11 is connected to an external air source. Since the output end of the flared pipe 12 is higher than the input end of the sludge pump 13, the gas has a strong disturbance effect on the sludge, which can loosen the sludge located in the lower part of the sedimentation tank 1, thereby improving the fluidity of the sludge, preventing the sludge from accumulating in dead corners, and facilitating discharge.

[0025] In summary, when using this automated sludge discharge control device, the ultrasonic sludge level gauge 4 is first immersed in water for 5-10cm. The height of the sludge layer is determined by analyzing the ultrasonic emission and the echo of the solid suspended matter in the water. Since the ultrasonic sludge level gauge 4 is electrically connected to the microcontroller and transmits sludge level information to the microcontroller, when the detected sludge level is greater than the threshold, the microcontroller controls the servo motor 302, cylinder 6, and sludge discharge pump 13 to run.

[0026] When the cylinder 6 works, it drives the travel plate 7 and the valve plate 8 to extend to the right a certain distance, so that the second air blowing pipe 11, the valve body 5, the first air blowing pipe 9, the folded corrugated pipe 10, and the flared pipe 12 are connected. At this time, the gas is introduced through the second air blowing pipe 11. Since the output end of the flared pipe 12 is higher than the input end of the sludge pump 13, the gas can strongly disturb the sludge, making the sludge located in the lower part of the sedimentation tank 1 loose.

[0027] The servo motor 302 provides rotational force to the lead screw 303 and the synchronous pulley 305. The motion and power are transmitted through the meshing of the teeth on the synchronous belt 306, the synchronous pulley 305, and the synchronous pulley 307, causing the lead screw 303 and the lead screw 308 to rotate synchronously. In turn, the two lead screw nuts 304 drive the mounting base 309 and the ultrasonic sludge level gauge 4 to perform horizontal reciprocating motion around the outside of the lead screw 303 and the lead screw 308, so as to detect the sludge level at different positions in the sedimentation tank 1, ensure the accuracy of sludge discharge, and improve the fluidity of sludge at different positions in the sedimentation tank 1, avoid sludge accumulation in dead corners, and facilitate the effective transfer of sludge to the sludge tank 2 by the sludge pump 13.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
