Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater internal circulation system for a belt conveyor. Background Technology

[0002] In the port's cargo loading, unloading and transportation system, belt conveyors play a crucial role and are widely used in the transportation of various bulk cargoes (such as coal, ore, grain, etc.).

[0003] Furthermore, because some bulk cargo often contains large amounts of dust, mud, and other impurities during mining, transportation, and storage, these impurities easily adhere to and accumulate on the belt surface when transported by conveyor belts. This can affect the normal operation of the conveyor belts, and in severe cases, directly cause conveyor belt malfunctions, leading to transport interruptions, reducing the efficiency of port cargo loading, unloading, and transportation, and impacting the overall operational efficiency and service quality of the port. Therefore, during the use of port conveyor belts, regular cleaning is necessary to ensure efficient, safe, and environmentally friendly port operations.

[0004] Currently, the operation and cleaning of belt conveyors and their drive units continuously generates large amounts of muddy water, which is typically introduced into surrounding sedimentation tanks. Because the muddy water is continuously generated and accumulated, dedicated personnel and machinery are required to regularly clean the sedimentation tanks. Therefore, the entire muddy water treatment process not only consumes a significant amount of manpower—workers need to spend time and energy operating various cleaning tools and transporting the removed sludge—but also consumes considerable resources, such as the purchase, maintenance, and operating costs of the cleaning equipment, and the resources needed for transporting the cleaned materials. Furthermore, since the materials in the sedimentation tanks are mostly muddy water mixtures, their high fluidity and instability during transportation to designated locations make spillage extremely likely. Once spilled, this leads to road sticking problems, causing roads to become muddy and triggering a series of environmental issues. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a belt conveyor wastewater internal circulation system that can treat and recycle the mud and water generated during belt conveyor cleaning to reduce frequent manual cleaning operations; it can also reduce the frequency of use of mechanical equipment for cleaning and transporting mud and water, and avoid road sticking problems caused by mud and water spillage, etc.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a belt conveyor wastewater internal circulation system, comprising a belt conveyor and a sedimentation tank. A suction pump is installed in the sedimentation tank, electrically connected to a control cabinet. The outlet of the suction pump is connected to a water supply pipeline, located above the conveyor belt in the belt conveyor. When the belt conveyor is used to transport materials (materials that can be watered) for peripheral process operations, it can control the suction pump to draw out the wastewater from the sedimentation tank and discharge it into the goods being transported by the belt conveyor, allowing it to be transported along with the goods to the stack location. Furthermore, throughout the process, on the one hand, the coordination between the belt conveyor and the goods ensures the wastewater is stably transported to the corresponding location, significantly reducing the frequency of sedimentation tank cleaning. The average cleaning frequency for each sedimentation tank is reduced from three times per week to once per week, avoiding spillage during wastewater transport. On the other hand, the wastewater can also help to add water and suppress dust and reduce cargo loss during transport, thereby reducing environmental pollution caused during material transport.

[0007] Furthermore, a liquid level detection device is installed inside the sedimentation tank, which can monitor the sewage level in the tank in real time. Based on the results from the liquid level detection device, staff can adjust the operation of the suction pump to prevent malfunctions due to no-load operation when the sedimentation tank is empty.

[0008] Furthermore, the liquid level detection device is an ultrasonic liquid level gauge, and its installation location is preferably set near the sewage pump.

[0009] Furthermore, the liquid level detection device is a float level gauge, and its installation location is preferably set near the sewage pump.

[0010] Furthermore, the belt conveyor is equipped with a material flow detection device, which can detect in real time whether there is any cargo on the belt conveyor. Based on the detection results, the operator can adjust the operation of the sewage suction pump, discharging sewage when there is cargo on the belt conveyor and not discharging sewage when there is no cargo, thus preventing sewage from spilling during belt operation due to the absence of cargo.

[0011] Furthermore, the material flow detection device includes a fixed frame fixedly installed above the belt conveyor. A proximity switch is fixedly installed in the middle of the fixed frame and is communicatively connected to the control cabinet. A trigger rod is vertically rotatably installed in the middle of the fixed frame. The rotation plane of the trigger rod is parallel to the material conveying direction of the belt conveyor. An arc-shaped contact plate is provided at the lower end of the trigger rod. When the arc-shaped contact plate comes into contact with the material being conveyed at the belt conveyor, the lower end of the trigger rod can rotate upward, and the upper end of the trigger rod can contact and trigger the proximity switch, thereby transmitting a signal to the control cabinet to indicate that there is material at the belt conveyor.

[0012] Furthermore, the sedimentation tank is equipped with a stirring device, which can be a common combination of a motor and a stirring frame, and installed in the sedimentation tank via a chain and a lifting frame.

[0013] As can be seen from the above technical solutions, this utility model has the following advantages: On the one hand, this utility model can stably transport sewage to the corresponding location through the cooperation of belt conveyor and goods, thereby greatly reducing the number of times the sedimentation tank is cleaned. The average number of times each sedimentation tank is cleaned is reduced from 3 times a week to 1 time a week, avoiding the problem of leakage during sewage transportation. On the other hand, this utility model can use sewage to add water to the transported materials to suppress dust and reduce the loss of goods, thereby reducing the environmental pollution caused during the material transportation process.

[0017] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] like Figure 1As shown, this utility model provides a wastewater internal circulation system for a belt conveyor, which includes a belt conveyor 6 and a sedimentation tank 1. A suction pump 4 and a stirring device 2 are installed at one corner of the sedimentation tank 1. Both the suction pump 4 and the stirring device 2 are installed inside the sedimentation tank 1 via a hoisting frame. The suction pump 4 is a submersible suction pump. The controller of the suction pump 4 is electrically connected to a control cabinet 5. The outlet of the suction pump 4 is connected to a water supply pipe 7, and the outlet of the water supply pipe 7 is positioned above the conveyor belt in the belt conveyor 6.

[0019] When belt conveyor 6 is used to transport materials (materials that can be watered) for peripheral process operations, it can control the suction pump 4 to suck out the sewage from the sedimentation tank 1 and discharge the sewage into the goods being transported by belt conveyor 6, so that it is transported together with the goods to the stack position, thereby realizing the discharge of sewage from the sedimentation tank 1. Moreover, in the entire sewage discharge process, the sewage can be absorbed by the goods being transported above belt conveyor 6 to prevent sewage spillage accidents during transportation; at the same time, the sewage can be used to suppress dust on the goods, thereby effectively curbing the generation and spread of dust during the transportation of goods and reducing environmental pollution caused by material transportation.

[0020] Furthermore, as a preferred embodiment, this invention can also install a liquid level detection device 3 inside the sedimentation tank 1, and use this device to monitor the liquid level of the wastewater in the sedimentation tank 1 in real time. This allows operators to adjust the operating status of the suction pump 4 based on the results detected by the liquid level detection device 3, preventing the suction pump 4 from malfunctioning due to no-load operation when there is no water in the sedimentation tank 1. Moreover, to improve the automation level of the entire system, the liquid level detection device 3 can be electrically connected to the controller of the suction pump 4, thereby utilizing a mature sensor feedback system to enable the suction pump 4 to automatically adjust its operating status based on the detection results of the liquid level detection device 3.

[0021] Meanwhile, this utility model can also be equipped with a material flow detection device at the belt conveyor 6 to detect whether there are goods on the belt conveyor 6 in real time, and the material flow detection device is located upstream of the water supply pipeline 7. In this way, the operator can adjust the working state of the sewage suction pump 4 according to the detection result of the material flow detection device, that is, discharge sewage when there are goods on the belt conveyor 6, and do not discharge sewage when there are no goods on the belt conveyor 6, thereby preventing sewage from spilling when the belt is running because there are no goods on the belt conveyor 6.

[0022] Specifically, the material flow detection device includes a fixed frame 11 fixedly installed above the belt conveyor. A proximity switch 10 is fixedly installed in the middle of the fixed frame 11 and is communicatively connected to the control cabinet. A trigger rod 9 is vertically rotatably installed in the middle of the fixed frame 11. The rotation plane of the trigger rod 9 is parallel to the material conveying direction of the belt conveyor 6. An arc-shaped contact plate 8 is provided at the lower end of the trigger rod 9, and the lower end of the arc-shaped contact plate 8 can contact the conveyor belt of the belt conveyor 6 when the trigger rod 9 is in a natural vertical state. When the lower end of the arc-shaped contact plate 8 contacts the material being conveyed at the belt conveyor, it can rotate vertically around the hinge point between the trigger rod 9 and the fixed frame 11. That is, when the lower end of the trigger rod 9 contacts the material being conveyed at the belt conveyor, it can rotate upward around the hinge point between the arc-shaped contact plate 8 and the fixed frame 11, and at the same time, the upper end of the trigger rod 9 contacts and triggers the proximity switch 10, thereby transmitting a signal to the control cabinet to indicate that there is material at the belt conveyor. In addition, as a preferred option, to improve the automation level of the entire system, the material flow detection device can be electrically connected to the controller of the sewage pump 4, thereby utilizing a mature sensor feedback system to enable the sewage pump 4 to automatically adjust its working state based on the detection results of the material flow detection device. At the same time, to solve the problem of frequent on / off switching of the sewage pump 4 caused by uneven material flow, this invention can also add a time-delay disconnection relay to the control circuit connecting the material flow detection device and the sewage pump 4, and set a 6-second delay. In this case, the sewage pump 4 will only stop running when the material flow is interrupted for 6 seconds, thereby effectively extending the service life of the equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
