Description

Technical Field

[0001] This utility model belongs to the technical field of diformamide waste liquid treatment equipment, and particularly relates to a feeding device for a diformamide waste liquid treatment tank. Background Technology

[0002] The diformamide waste liquid treatment tank is a special reaction vessel used to treat highly stable and difficult-to-degrade organic waste liquid containing diformamide (DMF). Its core function is to convert diformamide and other pollutants in the waste liquid into harmless or less harmful substances through physical, chemical or biological means (such as chemical neutralization, oxidative degradation, adsorption purification, etc.), while achieving solid-liquid separation to meet discharge standards or for recycling.

[0003] The quantitative feeding of solid materials is mainly achieved through an internal spiral mechanical structure. When the spiral rotor rotates, the material generates friction with the inner wall of the outer shell, and the material generates an outward pushing force during the spiral friction process. However, the inner spiral rotor is subjected to hard compression by the material. Even if the lower outer shell of the rotor does not contact the rotor, the compressed material and the inner wall of the rotor are subjected to great force, which results in the low practicality of conventional quantitative feeding structures for feeding diformamide waste liquid treatment tanks.

[0004] Therefore, we propose a feeding device for a diformamide wastewater treatment tank to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem that conventional quantitative pushing structures have low practicality for feeding diformamide wastewater treatment tanks, and to propose a feeding device for diformamide wastewater treatment tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for a diformamide wastewater treatment tank includes a servo geared motor. A frame is fixedly connected to the front of the servo geared motor's housing. A threaded cylinder and a gear are rotatably mounted on the upper part of the frame. The gear is fixedly connected to the output shaft of the servo geared motor. A toothed ring is fixedly connected to the outside of the threaded cylinder, meshing with the gear. A hopper is fixedly connected to the upper part of the frame, with its lower part extending into the interior of the threaded cylinder, but not in contact with it. Solid material is poured into the hopper, and an external power source drives the servo geared motor to rotate the gear. The gear then slowly rotates the toothed ring, and the threaded cylinder spirally guides the material forward for discharge. Precise quantity control is achieved by controlling the number of rotations. Compared to an internal spiral structure, this reduces wear and improves practicality.

[0007] Preferably, the frame includes a frame body, the housing of the servo geared motor is fixedly connected to the frame body, the gear ring does not contact the frame body, and a fixing frame is fixedly connected to the upper part of the frame body. The fixing frame is used to fix the feeding hopper, and the frame body is used to guide the rotation of the threaded cylinder.

[0008] Preferably, the frame further includes a fixing plate, which is fixedly connected to the lower part of the frame body. Screws are passed through the fixing plate to install the target pool body.

[0009] Preferably, the threaded cylinder includes a cylinder body, a spiral strip fixedly connected to the inner wall of the cylinder body, a toothed ring fixedly connected to the outside of the cylinder body, and the cylinder body rotatably connected to the upper part of the frame, with the cylinder body penetrating the frame body. When the toothed ring rotates, it drives the cylinder body to rotate, using gravity to keep the solid material on the lower side, causing the spiral strip to rotate and push out the solid material, thus facilitating the use of gravity and the spiral mechanical structure to push the solid material.

[0010] Preferably, the hopper includes a shell, the lower part of which is fixedly installed inside a fixed frame. A guide pipe is fixedly connected to the lower end of the shell. The internal spaces of the shell and the guide pipe are connected, and the lower part of the guide pipe is located inside the cylinder. Solid materials are introduced into the cylinder using the guide pipe.

[0011] Preferably, the gear includes a rotating shaft rotatably mounted within the frame. One end of the rotating shaft is fixedly connected to a gear holder, and the other end is fixedly connected to the output shaft of a servo geared motor. The gear holder meshes with a gear ring. The servo geared motor drives the rotating shaft to rotate, which in turn drives the gear holder to rotate, which in turn drives the gear ring to rotate, which in turn drives the threaded cylinder to rotate.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Solid materials are poured into the hopper, and an external power supply is used to drive a servo reduction motor to rotate the gears. The gears drive the gear ring to rotate slowly, and the spiral of the threaded cylinder guides the material forward to be discharged. The precise amount is controlled by controlling the number of rotations. Compared with the internal spiral structure, this reduces wear and improves practicality.

[0013] 2. When the toothed ring rotates, it drives the cylinder to rotate, using gravity to keep the solid material on the lower side, and the screw to rotate and push out the solid material, making it convenient to push the solid material using gravity and the screw mechanical structure.
