Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a solid reagent quantitative dosing device for wastewater treatment equipment. Background Technology

[0002] Wastewater treatment refers to the physical, chemical, and biological treatment of wastewater containing various organic, inorganic, suspended solids, microorganisms, and other pollutants generated in various fields such as urban areas, industry, agriculture, and medicine. The aim is to remove or reduce pollutants in wastewater and treat it to meet environmental water quality standards for safe discharge or recycling.

[0003] Wastewater treatment involves adding granular / powdered agents (such as flocculants in wastewater treatment), which are solid agents with poor flowability. Solid agents need to be transported in conjunction with screw conveyors or vibrating feeders. However, traditional solid agent dosing devices are prone to clumping and clogging, especially the discharge port of the storage hopper, which is prone to forming an arched material layer that blocks the discharge port.

[0004] Therefore, it is necessary to propose further solutions. Utility Model Content

[0006] The purpose of this utility model is achieved through the following technical solution: a solid reagent quantitative dosing device for sewage treatment equipment, comprising a frame, a storage funnel at the top of the frame, a discharge port at the bottom of the storage funnel, the discharge port being connected to the inlet of a vibrating conveying mechanism, and the outlet of the vibrating conveying mechanism being connected to the inlet of a metering feeding funnel; characterized in that an electromagnetic vibrator is installed on the outer wall of the storage funnel; an arch-breaking device is provided on the inner wall of its bottom, the arch-breaking device comprising a plurality of flexible swing rods evenly distributed around the discharge port, two adjacent flexible swing rods being staggered, and one end of the flexible swing rod being a connecting end, the connecting end being movably connected to the inner wall of the storage funnel, and the other end being a free end; the free end extending towards the discharge port, and a weight-increasing structure being provided inside the free end.

[0007] Preferably, the weight-adding structure is a stainless steel counterweight.

[0008] Preferably, the flexible swing rod has a highly elastic steel wire skeleton embedded along its length inside.

[0009] Preferably, the connecting end is connected to the inner wall of the storage funnel via a universal joint.

[0010] Preferably, the outer surface of the flexible swing rod is formed with spiral ridges along its length.

[0011] Preferably, the vibration conveying mechanism includes a trough, a vibration support, a vibrator, and a fixed column. The bottom of the trough is fixedly connected to the top of the vibration support. The four corners of the bottom of the vibration support are provided with mounting holes. One end of the fixed column is fixedly connected to the frame, and a resonant spring is sleeved on the end fixedly connected to the frame. The other end passes through the mounting hole and is tightened onto the resonant spring by a nut. The vibrator is installed on the vibration support to drive the vibration support to vibrate.

[0012] The beneficial technical effects achieved by this utility model are as follows: This application adds an arch-breaking device to the discharge port. The arch-breaking device is composed of a flexible swing rod and is driven by an electromagnetic vibrator to make the free end of the rod form a high-frequency micro-amplitude vibration in the discharge port area. At the same time, the local disturbance generated by the elastic deformation of the rod can accurately act on the arched accumulation layer, disintegrate the arch, effectively destroy the arched accumulation layer formed by the solid agent, and restore the material flowability.
