Description

Technical Field

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

[0002] In the production of pyromellitic acetic acid (PPA), solid waste mainly originates from filtration, washing, and separation processes. This waste includes, but is not limited to, unreacted raw materials, byproducts, and impurities generated during refining. During production, solid waste often contains a certain amount of moisture, which not only increases its volume and weight but may also affect the effectiveness of subsequent treatment or disposal. For example, drying solid waste with high moisture content before incineration can significantly improve incineration efficiency, reduce energy consumption, and help meet the operational requirements of the incinerator. Furthermore, water-containing waste is prone to bacterial growth, producing odors and increasing the risk of environmental pollution during transportation and storage.

[0003] Traditional drying devices typically dry waste materials directly after crushing them, but the drying effect is often unsatisfactory when there is a large accumulation of waste. Therefore, designing a drying device for waste treatment to overcome these technical shortcomings and improve overall practicality is of paramount importance. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for waste treatment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

One end of the vibrating filter assembly has a collection box, and at the bottom of the vibrating filter assembly is a guide cavity connected to a drying box. At the top of the drying box is a first guide plate, and at the bottom of the first guide plate are several second guide plates. One side of the drying box has several vent holes connected to an air supply pipe. The side of the drying box away from the vent holes has an air outlet pipe, and at the bottom of the drying box is a discharge pipe connected to a heated screw conveyor assembly. One end of the heated screw conveyor assembly has a discharge pipe connected to a circulation assembly.

[0007] As a preferred embodiment of this utility model, the chopping assembly includes symmetrically arranged rotating shafts, with a roller fixedly connected to the outside of the rotating shafts. Several blades are evenly spaced on the rollers, and a motor is provided at one end of the rotating shafts.

[0009] As a preferred embodiment of this utility model, the heated screw conveyor assembly includes screw blades, a conveying pipe, a drive motor, and a temperature sensor. The drive motor is used to drive the screw blades to rotate and convey materials. The conveying pipe includes an inner ceramic wear-resistant liner and an outer aluminum silicate fiber insulation layer. Resistance wire is wound around the outer wall of the conveying pipe, and a temperature sensor is provided on the outside of the conveying pipe.

[0010] As a preferred embodiment of the present invention, the circulation component includes a pump body, a first connecting pipe, and a second connecting pipe. One end of the first connecting pipe is connected to the pump body, and the other end of the first connecting pipe is connected to the discharge pipe. One end of the second connecting pipe is connected to the pump body, and the other end of the second connecting pipe is connected to the guide cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model provides a drying device for waste treatment. Utilizing a structure comprising a feeding box, a chopping assembly, a vibrating filter assembly, a screw conveyor assembly, and a circulation assembly, the material enters the feeding box through the inlet. First, the chopping assembly chops the material, preventing clumping after centrifugation and increasing the contact area between the material and hot air, accelerating the drying process. The chopped waste falls into the vibrating filter assembly at the bottom of the feeding box, where vibration filters out large particles and loosens the material for subsequent drying. The smaller particles then enter the drying chamber through a guide cavity. A hot air blower delivers hot air through an air pipe, allowing air circulation through several vents. Hot and humid air is discharged from the outlet pipe. The pre-dried material passes through a heated screw conveyor assembly, ensuring temperature maintenance during transport and guaranteeing the drying effect. If the humidity sensor detects insufficient humidity, the solenoid valve on the first connecting pipe is opened, and the solenoid valve on the outlet pipe is closed. The material then re-enters the drying chamber through the pump, the first connecting pipe, and the second connecting pipe, achieving material circulation and ensuring drying quality. This solves the problem of direct discharge of waste materials and liquids, which pollutes the environment and wastes resources. Attached Figure Description
