Embodiment 1

[0078] Put different dry powder materials in different storage bins; transport various dry powder materials from the storage bin to mixer 1 according to the addition ratio; stir different dry powder materials first, and then carry out the second stirring after an interval of 25 minutes. First stirring, wherein the stirring time of the first stirring and the second stirring are 40 minutes and 1 hour respectively, to make dry powder mortar. The dust generated during production passes through the condenser to reduce the dust temperature to 20°C, and then is sent to the bag filter 5 for dust removal. And the working temperature is maintained at 20°C during production. After testing, the AQI index of the working environment in the production process is maintained at 71-115, and the final product is relatively uniform.

Embodiment 2

[0080] Put different dry powder materials in different storage bins; transport various dry powder materials from the storage bin to mixer 1 according to the addition ratio; stir different dry powder materials first, and then carry out the second stirring after an interval of 35 minutes. First stirring, wherein the stirring time of the first stirring and the second stirring are 40 minutes and 1 hour respectively, to make dry powder mortar. The dust generated during production passes through the condenser to reduce the dust temperature to 20°C, and then is sent to the bag filter 5 for dust removal. And the working temperature is maintained at 20°C during production. After testing, the AQI index of the working environment in the production process is maintained at 63-85, and the final product is relatively uniform.

Embodiment 3

[0082] Put different dry powder materials in different storage bins; transport various dry powder materials from the storage bin to mixer 1 according to the addition ratio; stir different dry powder materials first, and then carry out the second stirring after an interval of 45 minutes. First stirring, wherein the stirring time of the first stirring and the second stirring are 40 minutes and 1 hour respectively, to make dry powder mortar. The dust generated during production passes through the condenser to reduce the dust temperature to 20°C, and then is sent to the bag filter 5 for dust removal. And the working temperature is maintained at 20°C during production. After testing, the AQI index of the working environment in the production process is maintained at 72-102, and the final product is relatively uniform.

Abstract

The invention belongs to the technical field of dry-mixed mortar and provides dry-mixed mortar production equipment. The dry-mixed mortar production equipment comprises a blender. A plurality of stock bins are arranged above the blender. The blender and the stock bins are connected with a bag type dust collector through air pipes. The bag type dust collector comprises a tank body. An upper partition plate and a lower partition plate are arranged in the tank body. An inner cavity of the tank body is divided into an exhaust chamber, a filtering chamber and an air inlet chamber which sequentially communicate with one another from top to bottom through the upper partition plate and the lower partition plate. A rotary support is arranged in the filtering chamber. A dust collection bag is arranged on the rotary support. The invention further provides a dry-mixed mortar production process using the dry-mixed mortar production equipment. The dry-mixed mortar production process comprises the following steps of feeding, blending, mixing and dust collecting, and dust cooling is conducted in the feeding step or the blending step or between the mixing step and the dust collecting step. The dry-mixed mortar production equipment and method are ingenious in conception, and the technical problem that in the prior art, the phenomena of bag blockage or upper opening damage of pulsed jet cloth filters are prone to occurring is solved.

Description

technical field [0001] The invention belongs to the technical field of dry powder mortar, and relates to a dry powder mortar production equipment and process. Background technique [0002] Dry powder mortar refers to a granular or powdery mixture of aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) that have been dried and screened in a certain proportion. , transported to the construction site in bags or in bulk, and can be used directly after mixing with water. Also known as mortar dry powder, dry mix, dry mix powder, some construction adhesives also belong to this category. Dry powder mortar plays the role of bonding, padding, protection and decoration in thin layers in the construction industry, and is widely used in construction and decoration engineering. However, at present, there is a lot of dust in the production of dry powder mortar, and the production environment is poor. Contents of the invent...
