Problems solved by technology

[0006] On the other hand, after being sprayed by the high tower, the fatty acid sodium component in the slurry volatilizes to a certain extent, and the volatilized part enters the exhaust gas dust removal system and adheres to the inner wall of the dust removal system, which reduces the efficiency of the dust removal system and increases the dust removal capacity of the dust removal system. The difficulty of cleaning; at the same time, due to the volatilization loss of the fatty acid sodium component, the active ingredients in the soap powder product are reduced, and the detergency of the product is reduced to a certain extent

Embodiment 1

[0047] Example 1 (base powder production process and system, the following percentages are weight percentages)

[0048] see figure 1 and 2 As shown, the solid raw materials Glauber's salt, soda ash, 4A zeolite, and small solid materials used in the base powder production system for producing base powder are sent to the solid raw material bin 20 through the solid raw material air conveying system. Liquid caustic soda, natron, sulfonic acid and process water are pumped into the liquid raw material header tank 30 respectively. After the liquid raw material is measured by the liquid raw material weighing scale 50, it is added into the batching pot 61, and the stirring device of the batching pot 61 is turned on. The solid raw material is added into the batching pot 61 after being measured by the solid material weighing scale 40 . The raw materials added in the batching pot 61 form slurry after being stirred, reacted and mixed. The slurry contains 18% soda ash, 20% 4A zeolite, 3...

Embodiment 2

[0051] (The after-mixing production process and system of washing powder base powder, powdery sodium fatty acid and other after-mixing raw materials, the following percentages are all weight percentages)

[0052] see figure 1 And and figure 2 As shown, the base powder from the powder spraying system is weighed 80% by the base powder loss-in-weight scale 81, and the discharge part of the soap powder loss-in-weight scale must be conveyed by a belt to prevent the material from being squeezed and agglomerated. Several solid raw materials from the rear batching bin are weighed 1% by enzyme preparation weight loss scale 82; Distribution of powdered raw materials. The powdery sodium fatty acid raw material is measured from a solid silo through a solid material loss-in-weight scale. The powdery sodium fatty acid weight loss scale 84 weighs 10%; the bottom of the feed bin of the rear batching bin should have a relatively large angle, so that under no external force, it is convenien...

Abstract

The invention discloses a process and equipment for producing laundry soap powder. The process comprises the following steps of: (1) delivering a solid raw material and a liquid raw material for production of base powder to a corresponding solid raw material bin and a corresponding liquid high-level storage tank, metering and then preparing the raw materials into slurry in an advanced preparation system, pressurizing the slurry by a high-pressure pump, feeding the slurry to a powder spray tower, atomizing and drying into the base powder; (2) feeding a powdered sodium aliphatate raw material to a powdered sodium aliphatate post-preparation raw material bin; and (3) adding the powdered sodium aliphatate raw material and base powder of the laundry soap powder as well as the post-preparation raw materials such as an enzymic preparation, an non-ionic essence and the like to a post-preparation rotary mixer, continuously and uniformly mixing into semi-finished laundry soap powder by the post-preparation rotary mixer, conveying the semi-finished laundry soap powder to a laundry soap powder bin through a laundry soap powder conveyor belt, and finally, packing the laundry soap powder into finished laundry soap powder. According to the process and the equipment for producing the laundry soap powder, the production efficiency of the laundry soap powder is improved, the energy consumption for the production of the laundry soap powder product is reduced, the insoluble substances in the laundry soap powder product is reduced, and the loss of the sodium aliphatate during production of the laundry soap power is reduced.

Description

technical field [0001] The invention relates to a production process of laundry soap powder, which belongs to the technical field of laundry powder production, and in particular to a method for measuring and adding fatty acid sodium raw materials in laundry soap powder raw materials. Background technique [0002] In order to adapt to the green and environmental protection development trend of daily chemical products, the production of washing powder products is developing towards energy saving and environmental protection in the production process, and the use of renewable resource raw materials for active substances in products. [0003] The raw materials of sodium fatty acid in laundry soap powder products are derived from animal and vegetable oils (or mixed animal and vegetable oils), which are renewable resource raw materials. Laundry soap powder products produced by partially replacing petroleum-based surfactants in laundry detergent products with fatty acid sodium raw ...
