Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic feeding devices, specifically relating to a height-adjustable hazardous waste hydraulic feeding device. Background Technology

[0002] With increasingly stringent environmental protection requirements, the standardized treatment of hazardous waste (hazardous waste) has become a key link in industrial environmental protection due to its toxicity, corrosiveness, flammability and explosiveness. In the hazardous waste treatment process, the feeding stage is the foundation for ensuring the efficient and safe operation of subsequent incineration, landfill and other disposal processes. The hydraulic tipping bucket feeder for hazardous waste treatment has emerged as a core piece of equipment to solve the problem of hazardous waste feeding.

[0003] In the treatment of hazardous waste, a hydraulic tipper is used to precisely feed the hazardous waste into the incinerator. The tipping angle and speed are controlled by hydraulics to avoid material accumulation affecting combustion efficiency or damage to the furnace body due to impact.

[0004] When existing hydraulic tippers are used as feeding devices in the process of hazardous waste treatment, their height is fixed. However, there are many types of hazardous waste, including solid, semi-solid, block or granular forms, and their bulk density varies greatly. When the tipper is used to feed and dump materials, excessively high dumping height can easily lead to material splashing or dust. Utility Model Content

[0005] The purpose of this invention is to provide a height-adjustable hydraulic hazardous waste feeding device, which aims to solve the problem that existing hydraulic tippers used in the hazardous waste treatment process have a fixed height. However, hazardous wastes are diverse, including solid, semi-solid, blocky, or granular forms with varying bulk densities. When the tipper is used to feed and dump materials, excessively high dumping heights can easily lead to material splashing or dust generation, especially for powdery or highly fluid materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable hazardous waste hydraulic feeding device, comprising a tipping bucket frame, with limiting blocks connected to both sides of the tipping bucket frame surface, the limiting blocks being slidably connected to a groove opened in the inner wall of the base frame, a servo motor mounted on the top surface of the base frame, a trapezoidal lead screw connected to the output end surface of the servo motor, the other side of the trapezoidal lead screw being sleeved in a bearing mounted on the base frame surface, a movable block movably sleeved on the longitudinal end surface of the base frame, and a movable block being threadedly connected to the trapezoidal lead screw surface.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides the following technical solution: a height-adjustable hazardous waste hydraulic feeding device, including a tipping frame 1, with limiting blocks 2 connected to both sides of the surface of the tipping frame 1, the surface of the limiting blocks 2 slidably connected to a groove opened in the inner wall of the base frame 3, a servo motor 4 installed on the top surface of the base frame 3, a trapezoidal lead screw 5 connected to the output end surface of the servo motor 4, the other side surface of the trapezoidal lead screw 5 sleeved in a bearing installed on the surface of the base frame 3, a movable block 6 movably sleeved on the longitudinal end surface of the base frame 3, the movable block 6 threadedly connected to the surface of the trapezoidal lead screw 5, the other side surface of the movable block 6 connected to both sides of the tipping frame 1, the bottom surface of the tipping frame 1 abutting against a rubber pad 7, and the top surface of the rubber pad 7... A threaded rod 8 is connected, and its surface is inserted into a circular groove at the bottom of the tipper frame 1. The bottom transverse end surface of the tipper frame 1 abuts against a nut 9, which is threaded onto the surface of the threaded rod 8. A spring 10 is connected to the bottom surface of a rubber pad 7, and its bottom surface is connected to the transverse end surface of a base frame 3. A limiting rod 11 is movably inserted into the transverse end surface of the base frame 3, and its top surface is connected to the bottom of the rubber pad 7. In this design, the tipper frame 1 is the main body of a hydraulic tipper, and a large number of related components are installed in the main body of the hydraulic tipper. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0024] The main model of the hydraulic tipper in this solution is: hydraulic tipper lifting and unloading equipment.

[0025] In operation: A motor-driven hydraulic pump generates high-pressure oil, which is delivered to the hydraulic cylinder via an oil circuit to drive the piston, causing the tipping bucket to rotate and lift. Once the tipping bucket reaches the preset height, the hydraulic system continues to drive it to tilt to 120°–150°, allowing the hazardous waste to be poured into the processing equipment along the guide channel. After unloading, the hydraulic oil circuit reverses, and the tipping bucket falls back to its original position under the action of hydraulic thrust and gravity. The entire process is automated by a PLC control system in conjunction with weighing and limit sensors. Furthermore, the design incorporates explosion-proof hydraulic oil and multi-layer seals to ensure a safe and controllable hazardous waste loading process, avoiding risks such as leakage and overloading.

[0026] Preferably, the base frame 3 is a U-shaped integrated structure, with two sets of T-shaped limiting grooves symmetrically opened on the inner wall of its longitudinal end, and the shape and size of the limiting grooves are adapted to the limiting block 2.

[0027] In actual use, when the trapezoidal lead screw 5 moves on the base frame 3, it causes the limiting blocks 2 on both sides of the tipper frame 1 to slide together on the base frame 3, so that the tipper frame 1 can move stably to adjust the height.

[0028] Preferably, two sets of servo motors 4, trapezoidal lead screws 5 and moving blocks 6 are symmetrically distributed on both sides of the longitudinal end of the base frame 3, and the thread directions of the two sets of trapezoidal lead screws 5 are opposite.

[0029] In practical use, the switch of the servo motor 4 is turned on at the same time, so that the trapezoidal lead screws 5 with opposite thread structures installed on both sides of the base frame 3 rotate under the drive of the output end of the synchronously driven servo motor 4, thereby causing the moving block 6 threaded on the trapezoidal lead screw 5 to move upward at the same time.

[0030] Preferably, a slot 12 is provided on the bottom surface of the base frame 3, a side block 13 is slidably connected to the surface of the slot 12, and the surface of the side block 13 is connected to the surface of the extension plate 14.

[0031] In practical use, the side blocks 13 connected to both sides of the extension plate 14 slide outward on the slot 12, thereby pulling out the extension plate 14.

[0032] Preferably, the surface of the extension plate 14 is threadedly connected to the transverse end of the fixing frame 16 using bolts 15, and the surface of the fixing frame 16 is connected to the lower end surface of the base frame 3.

[0033] In practical use, the side blocks 13 connected to both sides of the extension plate 14 slide outward on the slot 12, thereby pulling out the extension plate 14 to facilitate the adjustment of the position of the extension plate 14.

[0034] Preferably, two sets of slots 12 are symmetrically opened at the bottom of the base frame 3, and their shape and size are adapted to the side block 13 and the extension plate 14.

[0035] In practical use, the side blocks 13 connected to both sides of the extension plate 14 slide outward on the slot 12, thereby pulling out the extension plate 14. The bolt 15 passes through the threaded groove on the surface of the fixing frame 16 and is threaded to the threaded groove on the side of the extension plate 14 near the side block 13, thereby fixing the position of the pulled-out extension plate 14 on the fixing frame 16. The above operation is repeated to pull and fix the two sets of extension plates 14 on the fixing frame 16 respectively, thereby increasing the contact area between the base frame 3 and the ground.

[0036] Preferably, the fixing frame 16 has an inverted "U" shaped structure, and the shape and size of the rectangular cavity formed at its bottom are adapted to the extension plate 14.

[0037] In practical use, the rectangular cavity at the bottom of the fixing frame 16 facilitates the movement of the extension plate 14, and the threaded groove on the fixing frame 16 and the bolt 15 are used to thread the extension plate 14 and the fixing frame 16 together.

[0038] Working principle: When using the tipper frame 1 to process hazardous waste, depending on the hardness of the ground and the size of the site, unscrew the bolts 15 threaded between the extension plate 14 and the fixed frame 16. Then, pull the vertical plate at the top of the extension plate 14, and use the side blocks 13 connected to both sides of the extension plate 14 to slide outward on the slots 12, thereby pulling the extension plate 14 outward. The bolts 15 are then threaded through the threaded grooves on the surface of the fixed frame 16 and threaded onto the threaded grooves on the surface of the extension plate 14 near the side blocks 13, thus fixing the position of the pulled-out extension plate 14 on the fixed frame 16. Repeat the above operation to pull and fix the two sets of extension plates 14 onto the fixed frame 16, thereby increasing the contact area between the base frame 3 and the ground, allowing the tipper frame 1 to operate more stably and preventing it from tipping over. Then, depending on the properties of the hazardous waste to be fed and the height of the feed inlet of the connected processing equipment, simultaneously start the servo motor 4, causing the trapezoidal lead screws 5 with opposite thread structures installed on both sides of the base frame 3 to synchronously drive... Driven by the output of the servo motor 4, the moving block 6, threaded onto the trapezoidal lead screw 5, rotates, causing it to move upwards simultaneously. As the trapezoidal lead screw 5 moves on the base frame 3, it causes the limiting blocks 2 on both sides of the tipper frame 1 to slide along the base frame 3, allowing the tipper frame 1 to move stably and adjust its height for a better fit with the waste processing equipment. After reaching the preset height, the servo motor 4 stops running, and the electromagnetic controller mounted on it locks the trapezoidal lead screw 5. Simultaneously, the trapezoidal lead screw... The rod 5 has a self-locking property and its thread helix angle is less than the friction angle. The moving block 6 will not slide down by itself due to gravity or load. After the processing is completed, the above operation can be repeated to start the servo motor 4 to reverse it, thereby driving the tipping frame 1 to fall back to its original position. When the tipping frame 1 falls back to its original position, the spring 10 and rubber pad 7 connected to its bottom elastically buffer the impact force generated when the tipping frame 1 and the base frame 3 come into contact, avoiding the noise caused by the two directly rigidly contacting each other when falling, and at the same time providing buffer protection for the bottom of the tipping frame 1.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
