Description

Technical Field

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

[0002] In the field of hazardous waste treatment, the safety and stability of transfer equipment are paramount. However, some hazardous waste transfer equipment currently on the market has significant shortcomings, mainly in the following two aspects:

[0003] Lack of solid-liquid separation: Many hazardous waste transfer facilities are not equipped with solid-liquid separation devices, resulting in the mixing of solid and liquid waste inside the equipment. This mixing not only increases the complexity of waste treatment but may also trigger chemical reactions, generating new hazardous substances that pose a potential threat to the environment and the safety of operators.

[0004] Issues with Caster Wheel Movement and Fixing: Some transfer equipment uses caster wheels for movement, which facilitates handling. However, once at the processing location, the caster wheels cannot be effectively secured. This makes the equipment prone to movement during material unloading or processing, increasing operational instability and potentially leading to safety accidents.

[0005] A utility model patent entitled "A Transfer Device for Hazardous Waste Treatment," with authorization announcement number CN222512496 U, has the aforementioned problem. The patent's equipment design does not explicitly mention solid-liquid separation functionality and uses casters for movement, lacking an effective fixing device. This makes the equipment prone to movement during material discharge, failing to meet the requirements for safe transfer and treatment of hazardous waste.

[0006] Therefore, a hazardous waste transfer device is needed to improve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a hazardous waste transfer device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A hazardous waste transfer device includes a housing with an inlet at its upper end. Two sealing baffles are slidably mounted on both sides inside the inlet, driven by a cylinder. A solid discharge port is located on one side of the housing, with a first sealing baffle slidably mounted inside it, driven by a cylinder. A motor is fixedly mounted on the upper end of the housing, with a lead screw driven at its output end. A nut is threaded onto the surface of the lead screw, and a mesh plate is fixedly mounted on the surface of the nut.

[0010] As a preferred embodiment of this utility model, a plurality of feeding funnels are fixedly provided on the upper end of the device shell corresponding to the feed inlet.

[0011] As a preferred embodiment of this utility model, the device housing has a storage compartment inside, and the lower surface of the storage compartment has a drain outlet.

[0012] As a preferred embodiment of this utility model, the mesh plate is arranged in an inverted V shape and is adapted to the storage compartment.

[0013] As a preferred embodiment of this utility model, a second motor is fixedly installed at the lower end of the inner shell of the device, and a second lead screw is installed on both sides of the second motor for transmission.

[0014] As a preferred embodiment of this utility model, the lead screw is provided with an internal thread block on the two surfaces, and a hinge rod is provided on the surface of the internal thread block. The other end of the hinge rod is connected to the hinge arm.

[0015] As a preferred embodiment of this utility model, the inner surface of the device housing is provided with a rotating arm, and one end of the rotating arm is provided with a universal wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, through efficient separation and processing: the device receives waste material by injecting it into the feed inlet through a feeding funnel. Subsequently, cylinder two precisely drives sealing baffle two to move and close the feed inlet, effectively preventing leakage of waste material during the transfer process and ensuring the safety and environmental friendliness of the transfer. After motor one starts, it drives screw one to rotate, which in turn drives nut to move upward, enabling the mesh plate to efficiently separate solid and liquid objects. This separation method not only improves the efficiency of waste material processing but also facilitates the subsequent classification and processing of solid and liquid waste, reducing the complexity and cost of mixed waste material processing.

[0018] 2. The flexible waste discharge design of this utility model: The device is designed with a solid discharge port and a liquid discharge port. A cylinder drives a sealing baffle, which can flexibly open or close the solid discharge port to achieve precise discharge of solid waste. Simultaneously, liquid waste can be smoothly discharged through the liquid discharge port. This separate waste discharge design allows solid and liquid waste to be processed separately, avoiding secondary pollution that may result from mixed waste treatment, and improving the efficiency and environmental friendliness of waste treatment.

[0019] 3. Stable unloading and movement in this utility model: The device is equipped with casters at the bottom, making it more flexible and convenient to move, easily handling complex road conditions and confined spaces. When the device reaches the processing location, the second motor drives the second lead screw, which in turn drives the internal threaded block to move. This, in turn, pushes the rotating arm through the hinge rod, ultimately retracting the casters into the device's outer casing. This design not only maintains the stability of the device during unloading, preventing it from tipping over due to uneven ground or external forces, but also reduces the footprint of the device when stationary, improving space utilization.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] like Figures 1 to 5 As shown, the prior art in this embodiment has the following problems: The inventors found that the prior art lacks solid-liquid separation function: many hazardous waste transfer equipment are not equipped with solid-liquid separation devices, resulting in solid waste and liquid waste mixing inside the equipment. This mixed state not only increases the complexity of waste treatment, but may also trigger chemical reactions, producing new harmful substances, posing a potential threat to the environment and the safety of operators; problems with caster wheel movement and fixation: some transfer equipment uses casters for movement, which is convenient for handling, but the casters cannot be effectively fixed after arriving at the treatment location. This makes the equipment prone to movement during discharge or treatment, increasing operational instability and even potentially causing safety accidents;

[0029] Therefore, the inventor provides a hazardous waste transfer device, including a device housing 2. The upper end of the device housing 2 is provided with a feed inlet 9. The feed inlet 9 is slidably provided with two sealing baffles 8 on both sides. The sealing baffles 8 are driven by a cylinder 7. A solid discharge port 5 is provided on one side surface of the device housing 2. A sealing baffle 4 is slidably provided inside the solid discharge port 5. The sealing baffle 4 is driven by a cylinder 3. A motor 11 is fixedly provided at the upper end of the device housing 2. A lead screw 12 is driven at the output end of the motor 11. A nut 13 is threadedly connected to the surface of the lead screw 12. A mesh plate 14 is fixedly provided on the surface of the nut 13. Waste is injected into the feed inlet 9 through a feeding funnel 1. The cylinder 7 is started to move the sealing baffles 8 to close the feed inlet 9. The motor 11 is started to rotate the lead screw 12, thereby moving the nut 13 upward. The mesh plate 14 separates the solid and liquid objects. The solid discharge port 5 can be opened by the cylinder 3 to discharge the solid waste, and the liquid waste can be discharged through the liquid discharge port 6.

[0030] As an example of this utility model, a plurality of injection funnels 1 are fixedly provided on the upper end of the device housing 2 corresponding to the feed inlet 9. The design of multiple injection funnels 1 can improve the injection efficiency of waste materials and ensure that the device can quickly receive hazardous waste from different sources.

[0031] As an example of this utility model, the device housing 2 is provided with a storage chamber 10 inside, and a drain port 6 is provided on the lower surface of the storage chamber 10. The storage chamber 10 is used to temporarily store the separated liquid waste, and the drain port 6 is used to discharge the liquid waste from the device to ensure the classified treatment of the waste.

[0032] As an example of this utility model, the screen plate 14 is arranged in an inverted V shape and is adapted to the storage chamber 10. The inverted V-shaped screen plate 14 design can effectively increase the solid-liquid separation area and improve the separation efficiency. At the same time, the adaptation design with the storage chamber 10 ensures that the waste can smoothly enter the storage chamber 10.

[0033] As an example of this utility model, a second motor 19 is fixedly installed at the lower end of the inner shell 2 of the device. A second lead screw 18 is installed on both sides of the second motor 19 for transmission. The second motor 19 provides power for the movement and stability of the device, and the precise movement of the internal structure of the device is realized through the transmission of the second lead screw 18.

[0034] As an example of this utility model, the screw 18 is threadedly connected to an internal thread block 20, and the internal thread block 20 is hingedly connected to a hinge rod 15. The other end of the hinge rod 15 is hinged to the rotating arm 16. This structural design allows the device to drive the screw 18 and the internal thread block 20 through the motor 19 when needed, so as to realize the unfolding and retraction of the rotating arm 16.

[0035] As an example of this utility model, a rotating arm 16 is rotatably provided on the inner surface of the device housing 2. One end of the rotating arm 16 is rotatably provided with a universal wheel 17. The universal wheel 17 moves the device. When it reaches the processing location, the second motor 19 drives the second lead screw 18 to move the internal thread block 20. The hinge rod 15 pushes the rotating arm 16 to retract the universal wheel 17 into the device housing 2, keeping the device stable during unloading. The design of the universal wheel 17 allows the device to move flexibly, while the retraction mechanism of the rotating arm 16 and the universal wheel 17 ensures the stability of the device during unloading and prevents the leakage of hazardous waste due to the shaking of moving parts.

[0036] Working principle: During use, waste material is injected into the feed inlet 9 through the feeding funnel 1. The cylinder 2 7 is started to move the sealing baffle 2 8 to close the feed inlet 9. The motor 11 is started to drive the lead screw 12 to rotate, thereby driving the nut 13 to move upward. The mesh plate 14 separates the solid and liquid objects. The solid waste material can be discharged through the solid discharge port 5 by the cylinder 3 driving the sealing baffle 4, and the liquid waste material can be discharged through the liquid discharge port 6.
