Automatic mixing and spraying device and method applicable for perlite thermal insulation product

Abstract

The invention discloses an automatic mixing and spraying device and method applicable for a perlite thermal insulation product. The automatic mixing and spraying device comprises a box body of which the upper and lower sides are provided with an end cover and a base, and the interior of the box body is rotatably connected to a barrel body of which the side wall is connected to the inner wall of the box body through a limiting mechanism; the bottom of the barrel body is connected to the base through a rotating mechanism, and the bottom surface of the box body is provided with a communicating pipe; the top surface of the end cover is provided with a flow division box of which the bottom end is provided with a main liquid delivery pipe, and the outer side of the box body is uniformly providedwith spraying mechanisms connected to the flow division box through flow division pipes. The method comprises the steps of installation of the box body and the base, the rotating mechanism, the barrel body, the end cover and the spraying mechanisms, and mixing and spraying of the thermal insulation product. According to the automatic mixing and spraying device and method, the barrel body adopts arotation mode, and a stirring mechanism adopts a fixed mode; solutions are continuously delivered during stirring, and prevented from being solidified in the flow-forbidden state; and gas discharge is facilitated, and the internal pressure of the barrel body is reduced.

Description

technical field [0001] The invention relates to an automatic mixing and spraying device and method suitable for perlite thermal insulation products. Background technique [0002] Perlite thermal insulation products are light-weight thermal insulation products with a certain shape made of expanded perlite as raw materials, with small bulk density, good thermal insulation performance and stable chemical properties. Widely used in construction, chemical industry, petroleum, electric power, transportation and agricultural sectors, it is a good refractory material. [0003] The perlite thermal insulation products in the prior art are easy to cause the liquid to stick to the bottom of the barrel due to the use of a stirring mechanism to rotate and stir during the manufacturing process, and it is not conducive to continuous feeding, and the efficiency of automatic mixing and spraying is low, which is not conducive to Assembly line production, while increasing the labor intensity o...

Problems solved by technology

[0004] The purpose of the present invention is to provide a technical proposal for an automatic mixing and spraying device and method suitable for perlite thermal insulation products in view of the deficiencies in the prior art. The solution can be continuously transported while stirring, preventing the solution from solidifying in a state where the flow is prohibited, and it is convenient to discharge gas, reduce the pressure in the barrel, and prevent the liquid from clogging the feed pipe and liquid inlet pipe due to excessive pressure in the barrel. The spraying method of perlite thermal insulation products has simple steps and strong practicability, which can meet the needs of assembly line production technology, reduce the intensity and unevenness of manual operation, and improve the production quality of thermal insulation products
