An inlet pipe is located on the upper side surface of the wastewater tank, and a drain pipe is located on the lower side surface. A vortex-shaped groove is formed on the upper surface of the wastewater tank, connecting the inside and outside of the tank. An I-shaped slider is slidably mounted within the groove. A geared motor is installed at the center of the lower surface of the wastewater tank. The output shaft of the geared motor extends through the upper surface of the wastewater tank and connects to a rotating column. The side surface of the rotating column is connected to the slider via multiple telescopic rods. At least one ultrasonic depth gauge is mounted on the lower surface of the slider.

This trajectory covers most of the area from the edge to the center of the tank, allowing a single sensor to complete a large-scale scanning measurement of the wastewater tank's cross-section.

Description

Technical Field

[0001] This utility model relates to the field of mineral processing wastewater treatment technology, specifically a wastewater collection and monitoring device. Background Technology

[0002] Mineral processing generates large quantities of wastewater with complex compositions and high suspended solids content. This wastewater typically contains significant amounts of heavy metal ions, mineral processing reagents, and fine mineral particles, requiring effective sedimentation treatment to achieve solid-liquid separation before reuse or discharge in compliance with standards. When the sediment reaches a certain volume, it needs to be cleaned and recycled. Currently, monitoring the sludge level in mineral processing wastewater sedimentation tanks primarily relies on manual monitoring, with operators visually observing through observation windows on the tank sidewalls or using portable measuring tools for periodic measurements. This method is not only inefficient and labor-intensive but also highly subjective and produces discontinuous data. Some methods involve installing one or more ultrasonic depth gauges or hydrostatic sensors at fixed locations within the tank for monitoring. While this achieves automated monitoring, its monitoring range is limited to a single point directly below the sensor. Due to the complex composition of mineral processing wastewater, the sedimentation process is easily affected by factors such as influent flow rate, concentration, and reagent addition, resulting in varying sludge levels in different areas of the tank. Therefore, fixed single-point measurement cannot accurately reflect the sedimentation situation of the entire tank, and there are monitoring blind spots, which can easily lead to misjudgment or miss the best time for sludge discharge due to inaccurate local data, affecting processing efficiency and causing waste of resources. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a monitoring device for wastewater collection. It overcomes the limitation of fixed sensors that can only provide single-point data, and can obtain the true shape and height distribution of the sediment surface in the entire tank. The monitoring data is more representative and accurate, and the sediment can be cleaned and recycled in a timely manner, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wastewater collection monitoring device, comprising a wastewater tank, an inlet pipe provided on the upper side surface of the wastewater tank, a drain pipe provided on the lower side surface of the wastewater tank, a vortex-shaped groove provided on the upper surface of the wastewater tank, the groove connecting the inside and outside of the wastewater tank, an "I"-shaped slider slidably disposed in the groove, a reduction motor installed at the center of the lower surface of the wastewater tank, the output shaft of the reduction motor passing through the upper surface of the wastewater tank and connected to a rotating column, the side surface of the rotating column being connected to the slider through multiple telescopic rods, and at least one ultrasonic depth gauge installed on the lower surface of the slider.

[0005] As a preferred technical solution of this utility model, a number of water outlet pipes are evenly arranged from top to bottom on the side surface of the wastewater tank. Valves are installed on the water outlet pipes, and the ends of the water outlet pipes are all connected to the vertical pipes. The bottom end of the vertical pipes is connected to the drain pipe.

[0006] As a preferred technical solution of this utility model, a drain outlet is provided on the lower part of the side surface of the wastewater tank, and a sealing door is hinged at the drain outlet. The free end side surface of the sealing door and the side surface of the wastewater tank are provided with screw holes, and fixing bolts are connected to the screw holes by internal threads.

[0007] As a preferred embodiment of this invention, a handle is installed on the free end surface of the sealing door.

[0008] As a preferred technical solution of this utility model, the side surface of the slider that contacts the top plate of the wastewater tank is provided with a ball groove, and a ball is rolled in the ball groove.

[0009] As a preferred technical solution of this utility model, the upper surface of the slider is equipped with a mounting bracket by mounting bolts, and a slot is provided between the lower surface of the mounting bracket and the upper surface of the slider. A connecting rod is inserted into the slot, and hoppers for holding wastewater treatment agents are symmetrically installed at both ends of the connecting rod. The outlet of the hopper passes through a chute into the interior of the wastewater tank.

[0010] Compared with existing technologies, the advantages of this invention are as follows: A geared motor drives a rotating column, which in turn drives a slider equipped with an ultrasonic depth gauge via multiple telescopic rods. This slider moves along a pre-designed vortex-shaped groove trajectory, covering most of the area from the tank edge to the center. This allows a single sensor to complete a large-scale scanning measurement of the wastewater tank's cross-section. This overcomes the limitation of fixed sensors that only provide single-point data, enabling the acquisition of the true morphology and height distribution of sediment surfaces throughout the tank. The monitoring data is more representative and accurate, allowing for timely cleaning and recycling of sediment. Furthermore, the monitoring process is automatically completed by the motor, requiring no manual intervention, significantly reducing the operator's workload and subjective errors.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 This utility model provides a technical solution: a monitoring device for wastewater collection, including a wastewater tank 1, an inlet pipe 2 provided on the upper side surface of the wastewater tank 1, and a drain pipe 5 provided on the lower side surface of the wastewater tank 1. The inlet pipe 2 and the drain pipe 5 are used to transport wastewater generated by mineral processing and discharge mineral processing wastewater after sedimentation treatment, respectively.

[0015] The upper surface of wastewater tank 1 is provided with a vortex-shaped groove 14, which is a through groove, allowing connection between the inside and outside of wastewater tank 1. An "I"-shaped slider 12 is slidably mounted within the groove 14, engaging between the top plates of wastewater tank 1 separated by the groove 14, and sliding along the vortex-shaped groove 14. A reduction motor 10 is installed at the center of the lower surface of wastewater tank 1. The output shaft of the reduction motor 10 extends through the upper surface of wastewater tank 1 and connects to a rotating column 9. The side surface of the rotating column 9 is connected to the slider 12 via multiple telescopic rods 11. At least one ultrasonic depth gauge 13 is mounted on the lower surface of the slider 12. The reduction motor 10 drives the rotating column 9 to rotate, and the rotating column 9, through the multiple telescopic rods 11, drives the slider 12 and the ultrasonic depth gauge 13 to slide along the vortex-shaped groove 14. This allows for wide-range monitoring of the sediment height in wastewater tank 1, assisting manual judgment of the sediment height for timely cleaning and recycling. The monitoring process is automatically completed by motor drive, requiring no manual intervention, which significantly reduces the labor intensity and subjective error of operators.

[0016] The ultrasonic depth gauge 13 is preferably a non-contact air-mediated ultrasonic depth gauge, such as the air-mediated ultrasonic depth gauge with model number CSS-2022H. When it is installed on the upper part of the wastewater tank 1, it does not need to come into contact with the wastewater or immerse itself in the water surface to detect the sedimentation height. It also does not need to regularly clean the surface of the transducer, thus reducing maintenance costs.

[0017] When the rotating column 9 drives the slider 12 and the ultrasonic depth gauge 13 to slide along the vortex-shaped groove 14 via the multi-section telescopic rod 11, the multi-section telescopic rod 11 can freely extend and retract according to the distance between the slider 12 and the rotating column 9 to adapt to the current position of the slider 12. The structure is ingenious and the operation is stable. The geared motor 10 can be started periodically or irregularly according to the amount of wastewater entering, etc., to drive the ultrasonic depth gauge 13 to monitor the sedimentation height.

[0018] In a preferred embodiment, the side surface of the wastewater tank 1 is uniformly provided with several outlet pipes 3 from top to bottom. Each outlet pipe 3 is equipped with a valve 4, which can be a commonly used solenoid valve, to control the water flow from each outlet pipe 3. The ends of all outlet pipes 3 are connected to a vertical pipe, and the bottom of the vertical pipe is connected to a drain pipe 5; that is, all outlet pipes 3 are connected to the drain pipe 5. After the wastewater in the wastewater tank 1 undergoes sedimentation treatment, when the upper layer of wastewater can be discharged for further treatment or discharge, the valve 4 at the corresponding height (1-2 pipe positions above the highest point of the sediment) can be opened according to the sediment height monitored by the ultrasonic depth gauge 13. This allows the upper layer of wastewater to be discharged through the corresponding outlet pipe 3, maximizing the discharge of the sediment-treated mineral processing wastewater. Furthermore, the appropriate outlet pipe 3 can be flexibly selected based on the sediment height for drainage, improving operational flexibility.

[0019] The geared motor 10, solenoid valve, and ultrasonic depth gauge 13 used in this application are all electrically connected to an external controller and powered by an external power supply. The controller can be a commonly used PLC controller, such as a Siemens S7-1200 series PLC or a Schneider Modicon M221 PLC, or an embedded controller, such as an STM32F103 series. The controller, geared motor 10, solenoid valve, and ultrasonic depth gauge 13 are all commonly used electronic components in the prior art, and their specific structures, working principles, control methods, and circuit connections are all well-known technologies and will not be described in detail here.

[0020] In a preferred embodiment, a drain outlet is provided on the lower part of the side surface of the wastewater tank 1. An arc-shaped sealing door 6 is hinged to the drain outlet, and a sealing gasket is provided between the sealing door 6 and the drain outlet. Screw holes are provided on the free end side surface of the sealing door 6 and the corresponding location on the side surface of the wastewater tank 1, with fixing bolts 7 threaded into the screw holes. The sealing door 6 is fixed with the fixing bolts 7 to seal the drain outlet. When it is necessary to clean or recycle sediment, the upper layer of wastewater is drained, and then the fixing bolts 7 are unscrewed to open the sealing door 6, allowing the sediment to be cleaned or recycled through the drain outlet.

[0021] In a further preferred embodiment, a handle 8 is installed on the free end surface of the sealing door 6, making the operation of opening the sealing door 6 simpler and more convenient by pulling open the handle 8.

[0022] In a preferred embodiment, a ball groove is provided on the side surface of the slider 12 that contacts the top plate of the wastewater tank 1, and a ball 15 is rolled in the ball groove. By setting the ball 15, the sliding friction between the slider 12 and the top plate of the wastewater tank 1 is transformed into rolling friction, which can significantly reduce frictional resistance and operating noise, ensure the smooth and stable operation of the scanning monitoring device, and thus guarantee the accuracy of data acquisition and the service life of the equipment.

[0023] Optionally, a mounting bracket 18 is mounted on the upper surface of the slider 12 via mounting bolts 19. A slot is provided between the lower surface of the mounting bracket 18 and the upper surface of the slider 12. A connecting rod 16 is inserted into the slot. A hopper 17 for holding wastewater treatment agents is symmetrically mounted at both ends of the connecting rod 16. The outlet of the hopper 17 passes through a chute 14 into the wastewater tank 1. With the above configuration, the function of automatically adding wastewater treatment agents is integrated on the basis of the original monitoring function. Its working principle is as follows: When the reduction motor 10 starts, it drives the rotating column 9 to rotate, which in turn pulls the slider 12 along the vortex-shaped chute 14 via a multi-section telescopic rod 11. A connecting rod 16 is connected above the slider 12 via the mounting bracket 18 and the slot. A hopper 17 for holding agents is symmetrically mounted at both ends of the connecting rod. The movement of the slider 12 will synchronously drive the two hoppers 17 to move along the same vortex trajectory at the top of the wastewater tank 1. During the movement, wastewater treatment agents (such as flocculants) in the hopper 17 are continuously and evenly distributed throughout the entire area of ​​the wastewater tank 1 below through the outlet at its bottom. This allows the monitoring of sedimentation and the dosing of chemicals to be completed by the same drive system, achieving synergy and automation of monitoring and treatment, significantly improving treatment efficiency and reducing operating costs. Simultaneously, the hopper moves along a vortex trajectory with the slider, overcoming the problems of uneven agent distribution and insufficient mixing caused by traditional fixed-point dosing, enabling the agents to quickly contact a large area of ​​wastewater, fully exerting their efficacy, and significantly improving flocculation and sedimentation efficiency.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
