At the same time, in order to ensure production safety, a large number of high-cost heat-resistant packaging woven bags are required, which only increases the product packaging cost by about 330,000 yuan per year.
The soda cooler could not reach the expected designed production capacity, and also severely restricted the production capacity of the entire soda ash unit, resulting in an annual loss of about 15,000 tons of soda ash products

Embodiment Construction
[0034] The equipment and process of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as Figure 1~3 The device for reducing the temperature of soda ash in the soda cooling machine and the packaging post shown is based on the soda cooling machine 1 and the packaging post as the main equipment and production process. The upstream of the soda cooler 1 is connected to a calciner to cool down the soda ash product it produces. The packaging post is the end equipment of the production line, which packs the soda ash product into bags for transportation or storage.
[0036] The upstream side of the alkali cooler 1 is provided with a feed auger 2, and the downstream side is provided with a discharge auger 3. The feed auger 2 and the discharge auger 3 are both tube-type screw elevators; they can have an economical and durable conveying equipment that can lift materials and have a stirri...

The invention discloses a device and a method for reducing the temperature of soda ash in a soda ash cooling machine and a packaging post. The structure of the soda ash cooling machine and the production process of the packaging post are mainly improved. A feeding auger is arranged on the upstream side of the soda ash cooling machine and a discharging auger is arranged on the downstream side of the soda ash cooling machine; a feeding auger housing jacket is arranged in a housing of the feeding auger; a cooling water pipeline is further arranged on the feeding auger housing jacket; the downstream side of the discharging auger is connected with the packaging post, and an air suction pipeline is arranged in a packaging cabin and / or an on-cabin scraper plate of the packaging post; the other end of the air suction pipeline is connected with a bag type deduster and an induced draft fan. At the same time, a soda ash product from a calcining furnace and a soda ash product from the packaging post are cooled, so that the temperature of the soda ash product is in a safe range anytime without burnt bags. The efficiency for producing the soda ash can be improved and the packaging cost can be lowered, so that the economical benefit is increased.
Description
technical field [0001] The invention relates to the technical field of soda ash production, in particular to a device and a method for reducing the temperature of soda ash in a soda cooler and at a packaging post in a soda cooler process. Background technique [0002] In the soda ash manufacturing industry, the initial temperature of the soda ash product obtained in the combined soda calcination furnace is generally between 150 and 200°C. Due to the high temperature of the soda ash product, it must be cooled before packaging. At present, among the cooling soda technologies used in the soda ash industry, there are mainly several processes such as boiling soda furnace cooling, rotary soda furnace cooling and soda cooling machine. [0003] Among them, the boiling soda furnace needs to be pressurized and dehumidified, and a large amount of cooled dry air is used as the boiling medium. The contact between the material in the furnace and the air is more likely to affect the produ...
