Environment-friendly dispersion device for solid-liquid mixing

Abstract

An environmentally friendly dispersion device for solid-liquid mixing includes a material tank (1), a motor (2), a support (4), and a stirrer. It also includes a lifting mechanism (3), an airflow distribution plate (6), a duct (7), and a negative pressure tail gas recovery device (8). The stirrer consists of a stirring shaft and stirring blades (5). The stirring blades 5 are installed at the lower end of the stirring shaft, and the upper end of the stirring shaft is connected to the motor shaft extension via a coupling. In this dispersion device, an airflow distribution plate is installed in the material tank. The airflow distribution plate is connected to the duct, which is then connected in parallel to the negative pressure tail gas recovery device. Under negative pressure, the airflow distribution plate can draw in air, absorbing the dust and gas generated during the feeding and stirring processes, which then enters the recovery device, preventing the diffusion of dust and gas. The chemical production tail gas recovery device collects various tail gases generated during the production process, preventing direct emission of waste gas into the air and purifying the production environment.

Description

Technical Field

[0001] This utility model relates to an environmentally friendly dispersion device for solid-liquid mixing, belonging to the technical field of chemical production stirring and dispersion equipment. Background Technology

[0002] In daily production, mixing different chemical raw materials is a common process. Chemical raw materials involve solid, liquid, and gas phases, including solid-solid, solid-liquid, and liquid-liquid mixtures. For example, the production of coatings, plastics, and adhesives involves solid-liquid mixing. The production of these products often involves the use of powdered raw materials. When powdered raw materials are added to the liquid phase, mechanical stirring prevents them from dispersing immediately, causing spillage and dispersion of the powdered material. This often results in dust pollution around the production equipment or throughout the production workshop. This can range from minor environmental pollution to serious safety hazards, requiring serious attention.

[0003] To avoid the aforementioned problems in the solid-liquid mixing process, it is necessary to upgrade and modify the existing commonly used equipment. Through innovative modifications, similar phenomena can be avoided, making the chemical raw material mixing production process safer and more efficient. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of material overflow and dust pollution that exist in the solid-liquid mixing process involving the mixing of different chemical raw materials, and to propose an environmentally friendly dispersion device for solid-liquid mixing.

[0005] The technical solution implemented by this utility model is as follows: an environmentally friendly dispersion device for solid-liquid mixing, including a material bucket, a motor, a support and a stirrer, and also including a lifting mechanism, an airflow distribution plate, an air guide pipe and a negative pressure exhaust gas recovery device.

[0006] The material hopper is a vertical cylindrical structure with an opening at the top. A stirring shaft is installed at the central axis of the hopper, and stirring blades are installed at the lower end of the stirring shaft. The upper part of the stirring shaft is connected to the shaft extension of the motor through a coupling. The motor is installed on the cantilever beam of the support above the lifting mechanism. Eight identical airflow distribution plates are evenly distributed in the circumferential direction on the upper wall of the hopper top. The entire airflow distribution plate is welded to the inner wall of the hopper in an arc shape. The airflow distribution plates are connected to air guide pipes, and the air guide pipes are connected in parallel to a negative pressure exhaust gas recovery device.

[0007] The air flow distribution plate is a long strip of perforated steel plate, with both ends of its length direction closed and hollow inside. The cross-section of the air flow distribution plate is a rectangular return-shaped structure. For the air flow distribution plate with a circular arc on the long side of the cross-section, a plurality of air holes are opened on one side of its inner arc surface, and a hole is opened on one side of its outer arc surface, which is connected to the air guide pipe through the outer wall of the barrel on one side. The outer arc surface is welded and fixed to the arc surface of the barrel wall. The gap between the air guide pipe and the barrel wall is sealed.

[0008] The stirring blade realizes the up-and-down adjustment by adjusting the position of the stirring shaft through the lifting mechanism.

[0009] The negative pressure type waste gas recovery device is connected to the air guide pipe and provides negative pressure to the air flow distribution plate through the air guide pipe.

[0010] The beneficial effect of the present utility model is that the air flow distribution plate is installed in the material barrel in the present utility model. The air flow distribution plate is connected to the air guide pipe, and the air guide pipes are connected in parallel and then connected to the negative pressure type waste gas recovery device. Under the action of negative pressure, the air flow distribution plate can inhale air inward, so that the dust and gas generated in the feeding and stirring processes are absorbed by the air flow distribution plate and enter the recovery device, avoiding the diffusion of dust and gas and achieving the purpose of clean production.

[0011] The waste gas recovery device for the stirring and dispersing device can centrally collect various waste gases generated in the production process, avoid the direct discharge of waste materials and waste gases into the air, and play a role in purifying the production environment.
