Description

Technical Field

[0001] This utility model relates to the field of hazardous waste treatment technology, specifically to a hazardous waste liquid collection and transfer box. Background Technology

[0002] Wastewater treatment industry laboratories, online monitoring rooms, and machinery maintenance facilities are important sites for scientific research and production activities, but they are also significant sources of hazardous waste. Hazardous waste treatment is an important and complex task. Hazardous waste typically contains toxic, harmful, or corrosive substances, heavy metals, and organic pollutants; improper treatment can have serious consequences for the environment and human health.

[0003] Currently, the treatment process for hazardous liquid waste mainly includes several stages: collection, transfer, transportation, and final disposal. Among these, collection and transfer are crucial foundations for hazardous liquid waste management, directly impacting the effectiveness and safety of subsequent treatment. However, existing methods for collecting and transferring hazardous liquid waste have numerous problems (such as inadequate sealing and isolation during temporary storage, corrosion of surrounding ironware, and inaccurate and non-standard metering), making it difficult to meet increasingly stringent environmental protection requirements and actual production needs.

[0004] Currently, staff cannot monitor key information such as the weight of waste liquid inside the containers in real time, making it impossible to avoid the risk of spillage during operation. Operators struggle to accurately assess the collection status of waste liquid, which can easily lead to situations such as over-collection of containers or spillage during transfer, causing potential hazards. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing hazardous waste bins cannot know the status of waste liquid collection, which easily leads to inaccurate measurement, chaotic management, and waste liquid spillage and overflow causing danger. The purpose is to provide a hazardous waste liquid collection and transfer bin.

[0006] This utility model is achieved through the following technical solution:

[0007] A hazardous waste liquid collection and transfer box, comprising:

[0008] The protective box has a leak-proof collection port on the top, and the protective box is rotatably connected to a cover that seals the leak-proof collection port;

[0009] The collection bucket is located below the leak-proof collection port and is slidably arranged inside the protective box;

[0010] The control unit, located inside the protective box, is used to monitor the weight of the wastewater in the collection tank.

[0011] As a preferred technical solution, a funnel is detachably installed between the collection tank and the leak-proof collection port, and a holding part is connected to one side of the funnel. By setting the funnel, the funnel can connect the leak-proof collection port and the collection tank, and the funnel can guide the waste liquid to enter the collection tank stably, improving the safety of equipment use.

[0012] As one of the preferred technical solutions, a support block is provided inside the leak-proof collection port, and a positioning ring that cooperates with the support block is provided at the top of the funnel, with a sealing strip connected to the outer surface of the positioning ring.

[0013] By setting up a support block, on the one hand, the support block is a ring structure that matches the positioning ring to form a stable support; on the other hand, a sealing strip is set on the outer periphery of the positioning ring to abut against the inner wall of the leak-proof collection port. The sealing strip fills the gap between the inner wall of the leak-proof collection port and the funnel, preventing waste liquid from leaking from the funnel and causing pollution and harm.

[0014] As one of the preferred technical solutions, a slide rail is provided at the bottom of the protective box, a load-bearing chassis is slidably fitted on the top of the slide rail, and a weighing platform is provided on the top of the load-bearing chassis.

[0015] As one of the preferred technical solutions, the control unit includes a microcontroller, a weighing sensor, and an intelligent human voice prompter. The weighing sensor is disposed between the weighing platform and the supporting chassis. The intelligent human voice prompter and the display screen are both mounted on a protective box. The microcontroller is located on one side of the protective box and is electrically connected to the weighing sensor, the intelligent human voice prompter, and the display screen.

[0016] As a preferred technical solution, the protective box has an exhaust vent on its back, and a filter screen is installed at the exhaust vent. The exhaust vent ensures airflow inside the protective box, preventing the accumulation of harmful gases. Furthermore, the filter screen at the exhaust vent prevents dust from entering the protective box and causing contamination.

[0017] As a preferred technical solution, the bottom of the collection tank is also equipped with a leak-proof tray, which is located above the weighing sensor. If the collection tank is damaged due to handling or collision, the leak-proof tray can catch the leaked waste liquid, preventing contamination of the protective box; the edge of the tray can limit the flow range of the leaked liquid, reduce the risk of pollution spread, and reduce environmental remediation costs. Furthermore, the collection tank is made of acid- and alkali-resistant and corrosion-resistant material. Hazardous waste liquids have complex compositions and generally possess strong corrosive properties such as corrosivity, toxicity, flammability, and reactivity. Traditional containers are easily corroded and damaged after long-term contact with waste liquids, leading to leakage. Once a leak occurs, it will not only pollute the surrounding environment but may also cause safety accidents such as fires. Acid- and alkali-resistant and corrosion-resistant materials are chemically stable and do not easily react with other substances. As a preferred technical solution, both sides of the leak-proof tray are equipped with electric push rods. When it is necessary to remove the collection tank, activating the electric push rods will cause the collection tank and leak-proof tray to slide out of the protective box as a whole.

[0018] As one of the preferred technical solutions, the protective box has a door hinged to the front, and an electric lock that cooperates with the door is provided on one side of the protective box; a face recognition all-in-one machine is provided on the protective box, and the face recognition all-in-one machine has dual authentication function and is electrically connected to the electric lock.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0020] 1. The double-layer design of the protective box and collection bucket provides protection and sealing to the collection bucket, effectively preventing leakage of waste liquid and accumulation of harmful gases. Furthermore, the splash guard effectively prevents waste liquid from splashing and causing personal injury or environmental pollution when workers pour the liquid out, ensuring safety during the pouring process.

[0021] 2. By setting up a control component, the control component detects the weight of the waste liquid in the collection tank to determine whether the waste liquid is full, thereby facilitating timely processing of the collection tank and avoiding dangerous situations.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0031] Example 1: This utility model provides a hazardous waste liquid collection and transfer box, such as... Figure 1 and Figure 2 As shown, the device includes a protective box 1 and a collection bucket 2. The protective box 1 has a leak-proof collection port 5 on its top, which is cone-shaped with a larger top and a smaller bottom. The protective box 1 is rotatably connected to a top cover 6 that seals the leak-proof collection port 5. The collection bucket 2 is located below the leak-proof collection port 5 and is slidably arranged inside the protective box 1.

[0032] In this embodiment, the collection tank 2 is used to hold and store hazardous waste liquid, and has a capacity of 50L. The collection tank 2 is equipped with a protective box 1. That is, this embodiment uses a double-layer design to provide a certain degree of protection and sealing for the collection tank 2, effectively preventing the leakage of waste liquid and the accumulation of harmful gases.

[0033] In addition, the top of the protective box 1 is equipped with a cover 6. Under normal conditions, the cover 6 matches the top of the protective box 1, and the cover 6 closes the leak-proof collection port 5. It can be seen that the cover 6 is equipped with a handle on one side. The operator can pull the handle to flip the cover 6, thereby exposing the leak-proof collection port 5. When the staff collects the waste liquid, it is poured from the top of the protective box 1 into the collection bucket 2. At the same time, the leak-proof collection port 5 has a certain height on all four sides. During this process, the splashed waste liquid will be collected in the leak-proof collection port 5, thus effectively preventing the waste liquid from splashing and polluting the ground.

[0034] Furthermore, hazardous waste liquids have complex compositions and generally possess corrosive, toxic, flammable, and reactive properties. Traditional containers are easily corroded and damaged after prolonged contact with the waste liquid, leading to leakage. Once a leakage occurs, it will not only pollute the surrounding environment but may also cause safety accidents such as fires. Therefore, the collection bucket 2 in this embodiment is made of acid- and alkali-resistant and corrosion-resistant material. Specifically, the collection bucket 2 is made of polyethylene (PE) plastic, which achieves the following effects: First, PE material itself is chemically stable and does not easily react with other substances. The surface of the PE plastic bucket is smooth, making it difficult for dirt and impurities to adhere, and it is very easy to clean. Second, PE plastic buckets have a relatively low density and are lightweight. Third, PE material has a certain degree of flexibility and elasticity, and can withstand a certain degree of impact and collision without breaking.

[0035] To ensure that the protective box 1 can maintain good performance and appearance in harsh environments, the protective box 1 in this embodiment is made of corrosion-resistant and high-strength materials. Specifically, the frame of the protective box 1 is made of 304 stainless steel plate, and the top cover 6 is also made of 304 stainless steel plate to have corrosion resistance.

[0036] Furthermore, in this embodiment, the protective box 1 is equipped with support feet or casters on top. If support feet are provided at the bottom of the protective box 1, they bear the friction between the box and the ground, preventing wear caused by direct contact between the bottom of the box and the ground. If casters are provided at the bottom of the protective box 1, the transfer box can be easily pushed to the waste liquid generation location without the need for multiple people to carry it or with the aid of large lifting equipment, greatly reducing the labor intensity of the operators. It should be noted that operators can install casters or support feet according to actual needs.

[0037] Example 2, based on Example 1, differs from Example 1 in that: the protective box 1 has a hinged door 7 on its front, and an electric lock that cooperates with the door 7 is provided on one side of the protective box 1; a face recognition integrated machine 34 is provided on the protective box 1, which has dual authentication function and is electrically connected to the electric lock. That is, when the waste liquid in the collection bucket 2 is full, the staff uses the face recognition integrated machine 34 to perform dual authentication by swiping a card or password, or by face or fingerprint, and then pulls the embedded handle 8 to open the door 7, after which the collection bucket 2 is taken out for replacement and processing.

[0038] Specifically, the face recognition all-in-one machine 34 is an intelligent terminal device that integrates a face recognition algorithm, a camera, a second display screen, a second processor, and a communication module. It is mainly used for quickly and accurately verifying the identity of personnel. It achieves contactless identity verification by collecting the user's facial features and comparing them with pre-stored data.

[0039] The door 7 is equipped with an electric lock and uses facial recognition technology to open or close the door. The process is as follows: staff member A triggers the facial recognition device (such as a camera). When the camera is activated, it begins to scan the user's face in real time and determines whether the user is a specific staff member (whether they are in the database); at the same time, staff member A's permissions and timestamp are recorded.

[0040] Then, staff member B performs facial recognition, starting to scan the user's face in real time and determine whether the user is a specific staff member (whether they are in the database); staff member B's permissions and timestamp are recorded.

[0041] If one of the two individuals is an unauthorized person, or if both are unauthorized persons, the electronic lock remains closed. This design ensures that only authorized personnel who have both been verified can open the door 7 and retrieve the collection bin 2, increasing the overall security of the device. This process is existing and will not be described further. In this embodiment, the face recognition all-in-one machine is model DS-K1T, belonging to the Hikvision DS-K1T610 series.

[0042] Example 3, as Figure 1 As shown, the difference between this embodiment and Embodiment 1 is that a funnel 9 is detachably installed between the collection tank 2 and the leak-proof collection port 5. It is understood that since the collection tank 2 is located inside the protective box 1, there will be a certain gap between the leak-proof collection port 5 and the collection tank 2. During the pouring of waste liquid, the waste liquid may splash or leak out of the collection tank 2, causing adverse effects. In this embodiment, the funnel 9 connects the leak-proof collection port 5 and the collection tank 2, allowing the funnel 9 to guide the waste liquid stably into the collection tank 2, thus improving the safety of the equipment.

[0043] It is known that the diameter of funnel 9 is matched with the diameter of the leak-proof collection port 5 to ensure the normal pouring of liquid. Since funnel 9 also needs to come into contact with the waste liquid, the material of funnel 9 is also made of acid and alkali resistant material, such as PE plastic.

[0044] On the other hand, a holding part 10 is connected to the right side of the funnel 9. After pouring, the operator can use the holding part 10 to remove the funnel 9 and disassemble it, and then the funnel 9 can be cleaned.

[0045] Example 4, combined with Figure 1 and Figure 3 The difference between this embodiment and embodiment 2 is that: a support block 11 is provided inside the leak-proof collection port 5, a positioning ring 12 that cooperates with the support block 11 is fixedly installed on the top of the funnel 9, and a sealing strip 13 is connected to the outer surface of the positioning ring 12.

[0046] Because the pouring of waste liquid will generate a certain impact force on the funnel 9, and the static friction between the inner wall of the leak-proof collection port 5 and the funnel 9 alone cannot ensure the stable setting of the funnel 9, the funnel 9 may fall. Based on this, this embodiment provides a support block 11. It can be seen that, on the one hand, the support block 11 is a ring structure and matches the positioning ring 12 to form a stable support; on the other hand, a sealing strip 13 is provided on the outer periphery of the positioning ring 12, which abuts against the inner wall of the leak-proof collection port 5. The sealing strip 13 fills the gap between the inner wall of the leak-proof collection port 5 and the funnel 9, preventing waste liquid from leaking from the outside of the funnel 9 and causing problems. In addition, the sealing strip 13 increases the friction between the funnel 9 and the leak-proof collection port 5, further increasing the stability of the funnel 9.

[0047] Example 5, as Figure 2 As shown, the difference between this embodiment and embodiment 1 is that: a slide rail 15 is provided at the bottom of the protective box 1, and a bearing chassis 16 is slidably fitted on the top of the slide rail 15, and a weighing platform 4 is provided on the top of the bearing chassis 16.

[0048] Specifically, the supporting chassis 16 is made of 304 stainless steel, and the slide rails 15 consist of two linear slide rails. It can be seen that sliders are connected to both sides of the bottom of the supporting chassis 16, and these sliders are slidably connected to the corresponding slide rails 15. The collecting bucket 2 is supported on the supporting chassis 16, thus ensuring the normal and stable sliding of the collecting bucket 2. In addition, the top of the supporting chassis 16 is provided with multiple anti-slip ridges to increase the friction between the supporting chassis 16 and the collecting bucket 2, preventing the collecting bucket 2 from slipping.

[0049] Example 6, as Figure 1-4 As shown, the difference between this embodiment and embodiment 4 is that this embodiment also includes a control unit, which is located inside the protective box 1 and is used to monitor the weight of the wastewater in the collection bucket 2.

[0050] Specifically, the control unit includes a microcontroller 31, a weighing sensor 32, a display screen, and an intelligent human voice prompter 33. The weighing sensor 32 is disposed between the weighing platform 4 and the supporting chassis 16. In this embodiment, four weighing sensors 32 are provided, distributed at the four corners of the supporting chassis 16. When transferring the waste liquid, the weighing platform 4 is placed on the supporting chassis 16, and the supporting chassis 16 slides out along with the slide rail 15, along with the weighing sensors 32.

[0051] The intelligent human voice prompt device 33 and the display screen are both mounted on the protective box 1; the microcontroller 31 is located on one side of the protective box 1, and the microcontroller 31 is electrically connected to the weighing sensor 32, the intelligent human voice prompt device 33 and the display screen respectively.

[0052] In this embodiment, the MCU microcontroller 31 functions as follows: on the one hand, it receives data from the weighing sensor 32, performs data processing, cumulative calculation, and logical judgment; on the other hand, it saves the weighing data for each weighing and the total cumulative weight, and supports power-off memory.

[0053] The weighing sensor 32 is a high-precision resistance strain gauge pressure sensor with a measurement accuracy of ±0.1%FS (full scale) and a value range of 0-60kg. The weighing sensor 32 is installed on the top of the supporting chassis 16 and can contact the collection bucket 2 to sense the specific weight of the collection bucket 2.

[0054] The display screen is located on the front of the protective box 1 and is integrated into the face recognition all-in-one machine 34. It is used to display the weight value of the waste liquid tank, the cumulative weight, and alarm information. It can be a high-resolution color LCD screen. The display screen is connected to the microcontroller 31 via wired RS485.

[0055] The intelligent human voice prompter 33 is used to issue an alarm when the weight reaches a threshold. The threshold of the weighing sensor 32 is set to 45kg. When the total weight exceeds 45kg, the microcontroller 31 receives the overweight signal, performs calculations, and controls the intelligent human voice prompter 33 to issue a human voice prompt according to preset logic, such as "The waste liquid tank has reached the warning value, please handle it in time." Additionally, an LED indicator can be added to flash. For applications requiring a quiet environment, a vibration motor can be added as an auxiliary alarm method. It should be noted that the MCU microcontroller used in this embodiment is model CX3U258M-485, the weighing sensor is model SQB Keli series, and the intelligent human voice prompter is model CX_485A_A1.3.

[0056] The specific work process is as follows:

[0057] 1) Initialization: After the system is powered on, the microcontroller 31 performs a self-test and initializes parameters, including calibrating the weighing sensor 32 and setting the display screen. 2) Weighing Operation: The user places the collection bucket 2 on top of the supporting chassis 16. The weighing sensor 32 senses the weight change and converts it into an electrical signal, which is then transmitted to the microcontroller 31. 3) Data Processing and Display: The microcontroller 31 calculates the current weight and adds it to the total accumulated weight, then transmits the data to the display screen via wireless or wired connection. 4) Alarm Judgment: The microcontroller 31 monitors the total accumulated weight in real time. Once the weight exceeds the 45kg threshold, the intelligent human voice prompt device 33 immediately triggers an alarm.

[0058] Each time waste liquid is collected, approximately 1000ml is collected using the funnel 9 and splash-proof design. The weighing sensor 32 measures the weight of the waste liquid in real time and records it cumulatively. When the cumulative weight reaches 45kg, the controller issues an alarm to remind the operator to handle the situation promptly.

[0059] Example 7, as Figure 1 and Figure 2 As shown, the difference between this embodiment and embodiment 5 is that, to further prevent leakage of waste liquid, this embodiment also includes a seepage-proof tray 14, which is located at the bottom of the collection tank 2. The seepage-proof tray 14 is a square frame made of corrosion-resistant PP material. If the collection tank 2 is damaged due to handling or collision, the seepage-proof tray 14 can catch the leaked waste liquid, preventing contamination of the protective tank 1. The perimeter barrier structure of the tray can limit the flow range of the leaked liquid, reducing the risk of pollution spread and lowering environmental remediation costs.

[0060] In addition, the seepage-proof tray 14 is located above the weighing sensor 32. That is, the seepage-proof tray 14 is located above the supporting chassis 16, and the top of the supporting chassis 16 is equipped with a barrier that matches the seepage-proof tray 14 to limit the seepage-proof tray 14. Finally, the weighing sensor 32 is used to measure the weight of the seepage-proof tray 14 and the collection tank 2.

[0061] Example 8, if Figure 5 As shown, the difference between this embodiment and embodiment 6 is that both sides of the seepage-proof tray 14 in this embodiment are equipped with electric push rods 18. Specifically, the electric push rod 18 is an electric telescopic rod, with its fixed end connected to the rear side wall inside the protective box 1, and its telescopic end connected to the seepage-proof tray 14. That is, when it is necessary to remove the collection bucket 2, the electric push rod 18 is activated, and the electric push rod 18 extends and applies force to the seepage-proof tray 14. At this time, the collection bucket 2, the seepage-proof tray 14, and the supporting chassis 16 at the bottom of the seepage-proof tray 14 slide out of the protective box 1 as a whole under the action of the slide rail 15.

[0062] Example 9, as Figure 4As shown, the difference between this embodiment and Embodiment 1 is that an exhaust port 17 is provided on the back of the protective box 1, and a filter screen is installed at the exhaust port 17. By providing the exhaust port 17, air circulation inside the protective box 1 is ensured, preventing the accumulation of harmful gases. The exhaust port 17 ensures air circulation inside the protective box 1, forming internal and external air convection, and preventing the accumulation of harmful gases. In addition, in this embodiment, the exhaust port 17 is provided with a filter screen and activated carbon, and is made of corrosion-resistant material.

[0063] Specifically, the design of the exhaust vents ensures airflow inside the protective box 1, preventing the accumulation of harmful gases. On the other hand, it also allows for air convection between the inside and outside.

[0064] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
