Description

Technical Field

[0001] This utility model belongs to the field of saline wastewater treatment, and specifically relates to a simple wastewater collection device. Background Technology

[0002] With the continuous innovation and advancement of modern technology, the design and treatment scale of saline wastewater treatment systems in modern coal chemical industrial park wastewater reuse projects is becoming increasingly larger. These systems employ processes such as "membrane concentration + nanofiltration desalination + MVR evaporation and crystallization" to desalinate the effluent from the membrane concentration pretreatment unit of the industrial wastewater treatment system in the coal chemical industrial park wastewater reuse project. The reclaimed water is then reused, and crystallization produces byproducts such as sodium chloride and sodium sulfate. During this process, the equipment in the evaporation and crystallization workshop needs to be cleaned regularly. Traditional equipment feeding structures have limitations, lacking a separate design for equipment flushing water. During flushing, some of the wastewater generated enters the drying bed via the screw conveyor at the equipment's feeding port, causing the salt in the drying bed to become damp and clump together, affecting the stable operation of the drying bed and leading to a decrease in treatment capacity.

[0003] Traditional equipment only has one discharge trough. When the equipment is washed, it is necessary for people to stand next to the equipment with containers to collect the wastewater for a long time. When the number of equipment increases (often more than a dozen pieces of equipment on site need to be cleaned frequently) and wastewater needs to be collected, a large number of people are required to operate, which increases the maintenance workload. Utility Model Content

[0004] The purpose of this invention is to provide a simple wastewater collection device, thereby solving the problem of wasting human resources when manually collecting wastewater by standing next to the equipment with containers for a long time during equipment rinsing.

[0005] The technical solution adopted in this utility model is:

[0006] A simple wastewater collection device includes a first feeding trough, a second feeding trough located at the side end of the first feeding trough, the bottom of the first feeding trough being hollowed out for feeding materials during construction and production; a bottom plate is provided at the bottom of the second feeding trough, and a wastewater collection chamber is formed between the side wall of the second feeding trough and the bottom plate for collecting wastewater from cleaning equipment; multiple drainage holes are opened at one side end of the second feeding trough, and the multiple drainage holes are connected to a wastewater collection tank through drainage pipes.

[0007] Preferably, the top of both the first and second feeding troughs is equipped with centrifuge discharge port flanges.

[0008] Preferably, the centrifuge discharge port flange has multiple mounting holes on one side of the first discharge trough.

[0009] Preferably, each of the mounting holes is equipped with a cam lock for temporarily fixing the first feeding trough to the centrifuge feeding port.

[0010] Preferably, the outer ends of the multiple drain holes are provided with centrifuge flushing water drain pipes, which are connected to the drain pipes.

[0011] Preferably, the drain pipe is a rubber hose.

[0012] Preferably, the first feeding trough is provided with a push-pull handle on the side away from the second feeding trough.

[0013] The beneficial effects of this utility model are:

[0014] This utility model ensures normal material feeding during normal construction and production processes through the first feeding trough, without affecting the construction progress. The second feeding trough, located on the side of the first feeding trough, enables centralized collection of wastewater, ensuring stable operation of the equipment. Furthermore, the second feeding trough is well-sealed during the collection process, preventing corrosion of the equipment and thus avoiding impact on product quality.

[0015] Because the equipment only needs to be pulled out twice when switching between the first and second feeding troughs, it eliminates the need for personnel to be present at the equipment for extended periods, saving labor costs and reducing maintenance workload. It also enables rapid switching and separation between production and cleaning processes. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] In this utility model, the terms "longitudinal," "lateral," "vertical," "upper," "lower," "front," "rear," "left," "right," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The orientation or positional relationship shown is for the purpose of describing the present invention only, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0026] The simple wastewater collection device provided by this utility model is mainly used in the equipment cleaning scenario of the evaporation and crystallization workshop in the saline wastewater treatment system of a modern coal chemical industrial park's wastewater reuse project. It effectively collects wastewater generated during equipment rinsing, preventing wastewater from entering the next process stage, ensuring stable equipment operation, improving processing capacity, and saving labor costs. The specific implementation method of this device is described in detail below.

[0027] like Figure 1 As shown, the device consists of a first feeding trough 1 and a second feeding trough 2. Through a rational structural design, they work together to achieve the functions of material feeding during construction and wastewater collection. Both the first feeding trough 1 and the second feeding trough 2 are made of 304 stainless steel. 304 stainless steel has the advantages of a wide range of suitable working environments and is not easily corroded or rusted, ensuring the stability and reliability of the device during long-term use.

[0028] When setting up this device, its position at the centrifuge's discharge port must first be determined. A centrifuge discharge port flange 5 is welded to the top of the first discharge trough 1. The centrifuge discharge port flange 5 is used to temporarily fix one side of the first discharge trough 1 to the centrifuge's discharge port. Simultaneously, to ensure the sealing of the discharge process during the temporary fixing of the first discharge trough 1 to the centrifuge discharge port, a centrifuge discharge port flange 5 is also welded to the top of the second discharge trough 2. Multiple mounting holes 3 are opened on one side of the centrifuge discharge port flange 5 located on the first discharge trough 1. Each mounting hole 3 is equipped with a self-locking cam lock. The specifications of the cam locks are selected according to the weight of the device and the required installation stability. When temporary fixing is required, the device is placed at the predetermined position at the centrifuge discharge port, aligning the mounting holes 3 with the corresponding mounting holes on the centrifuge, and then the cam locks are tightened sequentially. The cam lock is existing technology, such as the snap lock of a toolbox—when the handle is rotated, the cam presses against the edge of the box, quickly locking the lid. This structure is widely used in industrial toolboxes (such as the Pelican safety box) and is a mature technology in the mechanical field.

[0029] Reference Figure 1-2The primary function of the first feeding trough 1 is for material feeding during construction and production. The bottom of the first feeding trough 1 features a perforated design, allowing materials to pass smoothly through during normal construction and production. The shape and size of the perforated portion are designed according to actual production needs and material characteristics, ensuring smooth material flow while preventing leakage or blockage due to excessively large openings. For example, if the material is a granular solid, the aperture of the perforated portion should be larger than the maximum particle size of the material, while ensuring a uniform distribution of aperture size to guarantee uniform material feeding.

[0030] The sidewalls of the first feeding trough 1 are made of sturdy 304 stainless steel plate, with the plate thickness selected based on the load-bearing capacity of the device and the operating environment. The sidewalls must be sufficiently high to prevent material from splashing out during the feeding process. The sidewalls are joined using welding, ensuring a strong and sealed weld to prevent material leakage during feeding. After welding, the welded areas are ground smooth to avoid scratching materials or operators.

[0031] Reference Figure 1 The bottom of the second discharge trough 2 is equipped with a base plate 21, which is made of the same 304 stainless steel as the sidewalls. The thickness of the base plate 21 is designed according to the load-bearing requirements of the device. The base plate 21 is tightly connected to the sidewalls to form a wastewater collection chamber for collecting wastewater from the cleaning equipment. Sealant is used at the joints to prevent wastewater leakage. The selection of the sealant takes into account its corrosion resistance, temperature resistance, and adhesion to the stainless steel material, ensuring that the sealing effect will not be lost due to wastewater corrosion or temperature changes during long-term use.

[0032] Reference Figure 1 , 3 Multiple drainage holes 22 are provided on one side of the second discharge trough 2. The number and diameter of the drainage holes 22 are designed according to the flow rate and drainage speed requirements of the wastewater. In this specific embodiment, four drainage holes 22 are provided, and the diameter of the drainage holes 22 is 10 mm. Each drainage hole 22 has a centrifuge flushing water drainage short pipe 23 at its outer end. The centrifuge flushing water drainage short pipe 23 is connected to the drainage hole 22 by welding or threaded connection. When using welding, the sealing and firmness of the connection must be ensured; when using threaded connection, a sealing ring needs to be added at the connection to prevent wastewater leakage. The centrifuge flushing water drainage short pipe 23 is connected to a drainage pipe, which is a rubber hose. The rubber hose has good flexibility and corrosion resistance, and can adapt to different installation environments and drainage requirements. One end of the rubber hose is connected to the centrifuge flushing water drainage short pipe 23 by a clamp, and the connection must be tight to prevent wastewater leakage; the other end is connected to the wastewater collection tank, and the collected wastewater is discharged to the wastewater collection tank for centralized treatment.

[0033] During normal construction and production, the first feeding trough 1 is positioned at the feeding port, and is temporarily fixed to the centrifuge feeding port using a cam lock on the centrifuge feeding port flange 5. At this time, material is fed normally through the hollowed-out portion at the bottom of the first feeding trough 1 for construction and production. Because the first feeding trough 1 is in tight contact with the equipment feeding port, material leakage is effectively prevented.

[0034] When cleaning the equipment is required, the operator first unlocks the cam lock on the centrifuge discharge port flange 5, and then holds the push-pull handle 4 located on the side of the first discharge trough 1 away from the second discharge trough 2. The second discharge trough 2 is then pulled out like a drawer to the discharge port, allowing for rapid discharge of cleaning wastewater. The push-pull handle 4 is made of stainless steel with a non-slip surface for easy operation. Once the second discharge trough 2 is pulled to the appropriate position, the wastewater generated during equipment rinsing will be collected in a groove with a base plate. The collected wastewater is then discharged to a wastewater collection tank for centralized treatment via the centrifuge rinse water drain pipe 23 and a rubber hose.

[0035] This device saves wastewater collection time and increases product output. Traditional wastewater collection methods require long hours of manual collection next to the equipment, which is inefficient. This device can collect wastewater quickly and effectively, allowing the equipment to resume production more quickly, thereby increasing product output.

[0036] Secondly, centralized wastewater collection ensures stable equipment operation. Traditional wastewater collection methods cannot effectively seal the wastewater, allowing small amounts to enter subsequent processes and affecting the equipment's dewatering efficiency and processing capacity. This device, through its rational structural design and sealing measures, ensures excellent sealing during wastewater collection, preventing wastewater from impacting the equipment and guaranteeing its stable operation.

[0037] Furthermore, the collection process is well-sealed, preventing corrosion of the equipment and ensuring product quality. The use of 304 stainless steel makes the device suitable for a wide range of working environments, resistant to corrosion and rust, and reducing subsequent maintenance. Simultaneously, the excellent sealing prevents wastewater leakage from damaging the equipment and products, guaranteeing product quality.

[0038] Furthermore, this device saves on labor costs and reduces maintenance workload. Traditional wastewater collection methods require a large number of personnel to operate, while this device only requires two pumping operations during switching, eliminating the need for personnel to be present at the equipment for extended periods, thus significantly reducing labor costs.

[0039] Finally, the device enables rapid switching between production and cleaning. During normal production, the first feeding chute is used for material feeding; during equipment cleaning, the second feeding chute is pulled to the discharge port to collect wastewater. The operation is simple and convenient, improving production efficiency.

[0040] With the continuous development of the modern coal chemical industry, the requirements for wastewater collection devices are becoming increasingly stringent. In the future, this simple wastewater collection device can be improved and optimized in the following aspects:

[0041] Intelligent Upgrade: The system incorporates sensors and an automated control system to enable real-time monitoring and automatic control of the wastewater collection process. For example, by installing a level sensor inside the second discharge tank 2, the liquid level in the wastewater collection chamber is monitored in real time. When the liquid level reaches a certain height, the drainage pump is automatically activated to discharge the wastewater into the wastewater collection tank, improving the efficiency and accuracy of wastewater collection.

[0042] Multifunctional integration: In addition to existing functions, more functional modules are integrated. For example, a water quality monitoring module can be added to the second feeding tank 2 to monitor various indicators of the collected wastewater in real time, providing data support for subsequent wastewater treatment; or a wastewater pretreatment function can be added to perform preliminary treatment on the collected wastewater, reducing the difficulty and cost of subsequent treatment.

[0043] Structural optimization: The structure of the device is further optimized to improve its stability and durability. For example, the connection between the first feeding trough 1 and the second feeding trough 2 is optimized to make it more robust and reliable; the design of the drain hole 22 and the centrifuge flushing water drain pipe 23 is improved to increase drainage efficiency and prevent clogging.

[0044] Expanding application scenarios: In addition to wastewater reuse projects in modern coal chemical industrial parks, this simple wastewater collection device can be applied to other scenarios requiring wastewater collection, such as food processing and pharmaceutical industries. By making appropriate improvements and optimizations to the device based on the characteristics and needs of different industries, its applicability and versatility can be enhanced.

[0045] This simple wastewater collection device, through its rational structural design and functional layout, effectively solves the problems existing in the traditional equipment flushing water collection process, offering numerous advantages such as saving wastewater collection time, ensuring stable equipment operation, and reducing labor costs. In practical applications, the device has demonstrated excellent performance and effectiveness, providing strong support for wastewater collection and treatment in modern coal chemical industrial zone wastewater reuse projects. Furthermore, the device is constructed of 304 stainless steel, making it suitable for a wide range of working environments, resistant to corrosion and rust, reducing subsequent maintenance work, and possessing high practicality and economic efficiency.
