Problems solved by technology

Among them, "towerless mixing molding method" is also called "one-step molding method". "Towerless mixing molding method" is to put all materials (powder raw materials, liquid raw materials, flavors, auxiliary materials, etc.) into the mixer in a preset order. Mix to prepare concentrated powder. The disadvantages of this process are: it belongs to intermittent production, the output is small, the labor intensity is high, the production of the product is restricted by the formula, and the powder has poor fluidity under strong mechanical stirring and grinding. , it is difficult to realize automatic packaging
The production system of agglomeration molding method is relatively complicated, mainly composed of raw material conveying system, solid-liquid metering control system, pre-mixing system, granulation system, drying and aging system, post-batching system, electrical control system, etc., and the main equipment is expensive and the investment high cost

Embodiment 1-1

[0038] Example 1-1 (Premix preparation process and system)

[0039] See figure 1 As shown, the schematic diagram of the equipment structure of the premix preparation system of the concentrated washing powder of the present invention. The premix mixes various solid raw materials (such as Glauber's salt, anhydrous sodium metasilicate, zeolite, soda ash) and liquid raw materials (such as nonionic surfactant AEO) according to its formula. 9 ) Are respectively sent to the corresponding solid raw material bin 10 and liquid high-level storage tank 20 via a wind conveying device and a liquid conveying device. The top of the solid raw material warehouse 10 is provided with a dust removal pipe 11 and a dust removal fan 12, which meets the requirements of clean production. The solid material is sent to the corresponding solid weighing hopper 14 under the push of the screw feeder 15, and the liquid material is driven into the liquid measuring tank 21 for standby.

Embodiment 1-2

[0042] Embodiment 1-2 (base powder production process and system)

[0043] See figure 1 with 2 As shown, the base powder from the high-tower spray system and the premix in the premix configuration system are produced simultaneously. Solid raw materials (such as Glauber's salt, anhydrous sodium metasilicate, zeolite, soda ash, etc.) and liquid raw materials (surfactant AES / AOS / AEO) used in the production of base powder for high-tower spray system 9 ) After passing through the corresponding conveying system and metering system respectively, it is added to the batching kettle 71 for stirring reaction. After the reacted slurry is aged by the aging kettle 72, it is transported by the high pressure (transport) pump 73 to the powder spraying tower 74 to complete the atomization. grain. The base powder from the powder spraying tower 74 is further aged and formed by the gas stripping tower 75, and then sent to the base powder bin 76 after sedimentation, separation and screening to comple...

Embodiment 1-3

[0044] Example 1-3 (Post-material conveying process and system)

[0045] See figure 2 and 3 As shown, other post-mixing materials (such as enzyme preparations, coloring materials, etc.) added in the rotary mixer (rotating drum) 60 are weighed by weight loss, collected on the conveyor belt and sent to the post-mixing rotary mixer. Flavors and some liquid raw materials (such as AEO 9 ) After passing through a separate metering device, it is driven into the rotary mixer 60, and mixed with the base powder and the premix in proportion to complete the preparation process of the concentrated powder. The semi-finished product from the rotary mixer 60 is sent to the packaging line by its storage and conveying system to complete the packaging of the semi-finished powder and complete the entire production process of concentrated washing powder.

[0046] In summary, the production process and equipment of the concentrated washing powder of the present invention are not used to produce a spe...

Abstract

The invention discloses a production technology and production equipment of concentrated detergent powder. The technology comprises the following steps of: processing main solid raw material and liquid raw material in a premixer (a horizontal ribbon mixer) into premix compound, conveying the premix compound into a revolving mixer (a drum) by a conveyer belt, and secondly mixing with base powder produced by a spray drying tower and other sequentially-prepared ingredients in proportion, and so that the concentrated detergent powder can be produced. The improvement and the breakthrough can be carried out based on the high-tower spray drying technology adopted by the conventional production technology of the detergent powder, and a premix compound preparing system is additionally arranged, so that the linkage processing of the premix compound, the base powder produced by the spray drying tower and other sequentially-prepared ingredients can be realized. According to the invention, the continuous production of the concentrated detergent powder can be realized, so that the yield of the concentrated detergent powder can be extremely improved; and a whole set of the system (the premix compound preparing system, a high-tower base powder spray producing system and a sequentially-prepared ingredient adding system) is applicable to the requirements of various formulas, so that some materials for producing can be flexibly mixed in the three unit systems.

Description

Technical field [0001] The invention relates to a washing powder production technology, belonging to the technical field of industrialized large-scale production of synthetic detergents, in particular to a production process and equipment of concentrated washing powder. Background technique [0002] With the rapid economic development and the continuous improvement of people's living standards, the consumer market has become increasingly calling for green and energy saving. In terms of detergents, reducing the use of non-effective chemicals and improving the utilization of effective chemicals have become important issues. The detergent industry at home and abroad has made active explorations. One of the most important measures is the concentration of washing powder. 化. [0003] At present, the main processes for producing concentrated washing powder in the industry are: "Towerless Hybrid Molding Method" and "Agglomeration Molding Method". Among them, the "non-tower hybrid molding ...
