Description

Technical Field

[0001] The present invention relates to the technical field of waste collection, and particularly to an automatic monitoring wastewater collection device. Background Art

[0002] With the rise of environmental protection industrial parks, there are fewer and fewer polluting enterprises retained in place. Enterprises have started to enter standardized industrial parks on a large scale, and the management of the wastewater quality in the parks has become one of the important management tasks upstream of the park water plants.

[0003] Existing wastewater collection devices face inconveniences in detection and sampling during actual application. Especially for discharge pipes with small flow rates and low water levels, since the device may not be able to reach below the liquid level for accurate sampling, this directly leads to significant errors in the detection results. In addition, the pollutant content in the wastewater varies at different flow rates, and the flow rate of the discharge pipe cannot be adjusted in real time during the sampling process, further exacerbating the error of the detection results. Summary of the Invention

[0004] The purpose of the present invention is to propose an automatic monitoring wastewater collection device to solve the problem that the pollutant content in the wastewater varies at different flow rates, and the flow rate of the discharge pipe cannot be adjusted in real time during the sampling process, further exacerbating the error of the detection results.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An automatic monitoring wastewater collection device includes a mounting frame and a drain pipe assembled on the mounting frame. One side of the drain pipe near the inlet end is connected with a water collection assembly through a shunt pipe;

[0007] The water collection assembly includes a water collection tank. The inner cavity of the water collection tank is divided into a water collection chamber and a monitoring chamber from top to bottom by a partition member. A plurality of sampling pipes communicating with the water collection chamber are threadedly connected to the top wall of the monitoring chamber. A water distribution assembly is assembled in the water collection chamber. After the wastewater enters the water collection chamber, it is driven by the water distribution assembly and sent into the sampling pipes at different positions for collection and sampling;

[0008] A spectrometer is assembled on the inner wall of the monitoring chamber to detect the wastewater in all the pipes after the sampling pipes are filled.

[0009] As a further description of the above technical solution:

[0010] The water collection assembly further includes a floating block slidably installed in the sampling pipe. A spring is fixed on the bottom wall of the sampling pipe, leaving a gap when the floating block is at the bottom of the sampling pipe.

[0011] As a further description of the above technical solution:

[0012] A one-way valve is assembled in the middle of the floating block, and a sealing member adapted to the inlet of the one-way valve is threadedly connected to the top inner wall of the sampling tube, so that the inlet of the one-way valve can be blocked when the floating block floats to the top of the sampling tube.

[0013] As a further description of the above technical solution:

[0014] The water collection assembly further includes a solenoid valve assembled on the shunt pipe to control the flow rate of the waste water entering the shunt pipe. One end of the solenoid valve is communicated with the water collection tank through a connecting pipe, and one end of the connecting pipe penetrates through the water collection tank and extends into the water collection cavity.

[0015] As a further description of the above technical solution:

[0016] The water distribution assembly includes a roller shaft rotatably connected in the water collection cavity. A conveyor belt is assembled on the two roller shafts, and a plurality of blocking strips for separating waste water are fixed on the conveyor belt.

[0017] As a further description of the above technical solution:

[0018] One end of the blocking strip is attached to the inner wall of the water collection cavity, so that the waste water entering the water collection cavity will not flow forward through the blocking strip.

[0019] As a further description of the above technical solution:

[0020] A maintenance door is detachably fixed to the front of the water collection tank. One end of each roller shaft is rotatably connected to the inside of the maintenance door. A motor is assembled on the maintenance door, and the output end of the motor penetrates into the water collection cavity and is splined to one of the roller shafts.

[0021] As a further description of the above technical solution:

[0022] A water discharge assembly is assembled on one side wall of the monitoring cavity. The water discharge assembly includes an electric push rod rotatably connected to the inner wall of the monitoring cavity, and a cross bar is assembled at one end of the electric push rod.

[0023] As a further description of the above technical solution:

[0024] A water discharge port is opened on the inner bottom wall of the sampling tube. The bottom end of the sampling tube is rotatably connected with a sealing cover. The bottom of the sealing cover is rotatably connected with a connecting seat. One end of the connecting seat is fixed to the cross bar, so that the electric push rod can control a plurality of sealing covers through the cross bar.

[0025] As a further description of the above technical solution:

[0026] A lower water trough is provided on the side of the bottom wall of the water collecting chamber away from the connecting pipe, so that the waste water in the water collecting chamber can flow into the monitoring chamber. The water collecting box is connected to the drain pipe through a lower water pipe installed at the bottom, so that the waste water in the monitoring chamber can flow into the drain pipe.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] By setting up the water collection component and the water distribution component, the flow rate entering the diversion pipe is controlled by the electromagnetic valve, so that the water collection chamber can collect wastewater at different flow rates, and then collect wastewater at different flow rates for detection, making the detection result more accurate;

[0029] At the same time, the conveyor belt moves with the baffle bar so that the sewage of the same batch can be separated and then enter the sampling tubes at different positions for collection, thereby further improving the accuracy of the detection. During the movement of the baffle bar, the particulate matter remaining on the inner wall of the water collection chamber after the wastewater flows away can be scraped away, so that this particulate matter will not mix with the wastewater flowing in next time, thereby avoiding affecting the next test results.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] As Figure 1 - Figure 8 shown, the present invention provides:

[0048] An automatic monitoring waste water collection device, including a mounting frame 10 and a drain pipe 20 assembled on the mounting frame 10. Preferably, a control valve is installed on the drain pipe 20, and the drainage flow rate of the drain pipe 20 can be controlled through the control valve. One side of the drain pipe 20 close to the inlet end is connected to a water collection assembly 40 through a diverting pipe 30;

[0049] The water collection assembly 40 includes a water collection tank 41. The inner cavity of the water collection tank 41 is divided into a water collection cavity 44 and a monitoring cavity 45 from top to bottom through a partition member 43. A plurality of sampling pipes 46 communicating with the water collection cavity 44 are threadedly connected to the inner top wall of the monitoring cavity 45. A water distribution assembly 50 is assembled in the water collection cavity 44. After the waste water enters the water collection cavity 44, it is driven by the water distribution assembly 50 to be respectively sent into the sampling pipes 46 at different positions for collection and sampling;

[0050] The water collection assembly 40 further includes a solenoid valve 49 assembled on the shunt pipe 30. Preferably, the solenoid valve 49 is a proportional solenoid valve, so that the flow rate of the wastewater entering the shunt pipe 30 can be controlled. One end of the solenoid valve 49 is connected to the water collection tank 41 through a connecting pipe 410. One end of the connecting pipe 410 penetrates through the water collection tank 41 and extends into the water collection cavity 44;

[0051] More specifically, after separating the inner cavity of the water collection tank 41 into a water collection cavity 44 and a monitoring cavity 45, the separation of wastewater collection and subsequent monitoring is realized. And the setting of multiple sampling pipes 46 enables the same batch of wastewater to be sampled multiple times;

[0052] Specifically, during the actual collection process, the solenoid valve 49 can be controlled to control the wastewater entering the shunt pipe 30, so that wastewater with different flow rates enters the water collection cavity 44 through the connecting pipe 410. When a certain amount of wastewater with the same flow rate flows in, the solenoid valve 49 is closed. Then, under the blockage of the water distribution assembly 50, the wastewater will stay at the front end. At this time, the wastewater will first enter the sampling pipe 46 at the front end position.

[0053] As Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown in, the water distribution assembly 50 includes a roller shaft 51 rotatably connected in the water collection cavity 44. A conveyor belt 52 is assembled on the two roller shafts 51 together. A plurality of blocking strips 53 for separating wastewater are fixed on the conveyor belt 52. One end of the blocking strip 53 is attached to the inner wall of the water collection cavity 44, so that the wastewater entering the water collection cavity 44 will not flow forward through the blocking strip 53;

[0054] A maintenance door is detachably fixed on the front of the water collection tank 41. One end of each roller shaft 51 is rotatably connected to the inside of the maintenance door. A motor 54 is assembled on the maintenance door. The output end of the motor 54 penetrates into the water collection cavity 44 and is splined to one of the roller shafts 51;

[0055] A water discharge groove is formed on the inner bottom wall of the water collection cavity 44 away from the connecting pipe 410, so that the wastewater in the water collection cavity 44 can flow into the monitoring cavity 45. The water collection tank 41 is connected to the drain pipe 20 through a drain pipe 42 installed at the bottom, so that the wastewater in the monitoring cavity 45 can flow into the drain pipe 20;

[0056] Specifically, after the sampling tube 46 at the front end position has finished collecting, the motor 54 is started to control the roller 51 to rotate, thereby causing the conveyor belt 52 to move with the baffle 53, so that the wastewater enters the middle position. At this time, this part of the wastewater will enter the sampling tube 46 at the middle position, and then the conveyor belt 52 is continued to drive the baffle 53 to move, so that the wastewater enters the rear position and enters the sampling tube 46 at the rear position. At this time, the wastewater is collected in the three sampling tubes 46 respectively, and the excess wastewater continues to run through the conveyor belt 52, is pushed backward by the baffle 53, and falls into the monitoring chamber 45 through the lower sink, and finally flows into the drain pipe 20 through the lower water pipe 42;

[0057] Preferably, during the process of water entering the water collecting chamber 44, the motor 54 is started at the same time to make the conveyor belt 52 drive the baffle 53 to move, and the baffle 53 separates the wastewater and guides it to different sampling tubes 46, so that the sampling tubes 46 at different positions can quickly collect the wastewater without the need for gradual collection, thereby avoiding the deposition of particulate matter in the wastewater during the waiting process of gradual collection.

[0058] like Figure 2 , Figure 3 and Figure 7 As shown, the water collection assembly 40 also includes a float 47 slidably mounted in the sampling tube 46, and a spring 48 is fixed on the inner bottom wall of the sampling tube 46, so that a gap is left when the float 47 is at the bottom of the sampling tube 46;

[0059] A one-way valve 412 is installed in the middle of the float 47, and a sealing member 411 matching the inlet of the one-way valve 412 is threadedly connected to the top of the inner wall of the sampling tube 46, so that the inlet of the one-way valve 412 can be blocked when the float 47 floats to the top of the sampling tube 46;

[0060] In further detail, during the process of water entering the sampling tube 46, the wastewater flows to the bottom of the sampling tube 46 through the one-way valve 412 in the middle of the float 47, and the float 47 gradually floats up as the water level continues to rise, until the float 47 abuts against the sealing member 411, at which time the inlet of the one-way valve 412 is blocked, and the wastewater can no longer enter the tube. When the baffle 53 drives the wastewater to move toward the middle and rear, the wastewater will not mix with the wastewater collected in the tube;

[0061] In particular, when water is introduced into the water collecting chamber 44, the motor 54 is started at the same time to make the conveyor belt 52 drive the baffle 53 to move, and the baffle 53 separates the waste water and guides it to different sampling tubes 46. At this time, the waste water will not affect each other when entering the sampling tubes 46, so the floating block 47 and the sealing member 411 can be taken out in advance.

[0062] like Figure 4As shown, a spectrometer 60 is assembled on the inner wall of the monitoring chamber 45 to detect the wastewater in all sampling tubes 46 after the sampling tube 46 is filled. Preferably, the spectrometer 60 is a multi-channel spectrometer capable of simultaneously detecting the wastewater in multiple sampling tubes 46. Through the spectrometer 60, it is possible to;

[0063] As Figure 5 , Figure 6 and Figure 7 As shown, a water discharge assembly 70 is assembled on one side wall of the monitoring chamber 45. The water discharge assembly 70 includes an electric push rod 71 rotatably connected to the inner wall of the monitoring chamber 45, and a cross bar is assembled at one end of the electric push rod 71;

[0064] A water discharge port is provided on the inner bottom wall of the sampling tube 46. The bottom end of the sampling tube 46 is rotatably connected to a sealing cover 72. The bottom of the sealing cover 72 is rotatably connected to a connecting seat, and one end of the connecting seat is fixed to the cross bar, so that the electric push rod 71 can control multiple sealing covers 72 through the cross bar;

[0065] More specifically, after a detection is completed, the electric push rod 71 is started to drive the cross bar to move backward, thereby pulling the sealing covers 72 at the bottom ends of all sampling tubes 46 to rotate backward, so that the water discharge ports are opened, and the detected wastewater is discharged. During the discharge process, the floating block 47 gradually descends, and the residues on the pipe wall can be scraped off to avoid affecting the next detection. After complete discharge, the sealing cover 72 is reset by the electric push rod 71, and the discharged water flows into the drain pipe 20 through the drain pipe 42.

[0066] Specifically, when this automatic wastewater monitoring and collection device is working / being used:

[0067] 1. Preparation stage: Ensure that the mounting frame 10 is stable, and the components such as the drain pipe 20, the shunt pipe 30, and the water collection assembly 40 are correctly connected. Check the functions of electronic devices such as the solenoid valve 49, the motor 54, the spectrometer 60, and the electric push rod 71. According to needs, decide whether to install the floating block 47 and the hole sealing member 411 (for continuous collection, it can be not installed to reduce steps).

[0068] 2. Wastewater collection stage: Start the solenoid valve 49 to control the wastewater flow rate entering the shunt pipe 30, and adjust the opening degree of the solenoid valve 49 according to needs to make the wastewater enter the water collection chamber 44 through the connecting pipe 410;

[0069] Start the motor 54 (if the simultaneous collection method is adopted): Make the conveyor belt 52 drive the blocking strips 53 to rotate, separate and guide the wastewater to different sampling tubes 46;

[0070] Or (if the gradual collection method is adopted): First, let the wastewater stay at the front end. After a certain amount of wastewater has accumulated, close the solenoid valve 49, and then start the motor 54 to gradually push the wastewater to each sampling pipe 46. During this process, the floating block 47 functions (as installed): The wastewater enters the sampling pipe 46 through the one-way valve 412, and the floating block 47 rises with the water level until it blocks the inlet of the one-way valve 412.

[0071] 3. Wastewater monitoring stage: Ensure that an appropriate amount of wastewater is collected in all sampling pipes 46, and then start the spectrometer 60 to simultaneously detect the wastewater in multiple sampling pipes 46 to obtain water quality data.

[0072] 4. Wastewater discharge stage: After the detection is completed, start the electric push rod 71: drive the cross bar to move, open the sealing covers 72 at the bottom ends of all sampling pipes 46, so that the wastewater is discharged through the water discharge port, and then flows into the drain pipe 20 through the down pipe 42. At the same time, the floating block 47 descends to scrape the residues on the pipe wall, and then the electric push rod 71 closes the sealing covers 72 at the bottom ends of the sampling pipes 46 again to prepare for the next collection.

[0073] 5. Maintenance and repair: Regularly check the working status of the solenoid valve 49, the motor 54, the spectrometer 60, and the electric push rod 71. Check the inside of the water collection tank 41 through the detachable inspection door, and maintain and repair components such as the water distribution component 50.
