Description

Technical Field

[0001] The utility model belongs to the technical field of boilers, and specifically relates to a new boiler for producing silica sol. Background Art

[0002] Silica sol is a dispersion of nano-scale silicon dioxide particles in water or solvent. There are different ways to prepare silica sol. The most commonly used methods are ion exchange, one-step hydrolysis of silicon powder, silane hydrolysis, etc. Boiler is an energy conversion device. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's lives, and can also be converted into mechanical energy through steam power devices. In the production process of silica sol, a boiler is required to provide high-temperature steam.

[0003] Publication (Announcement) No.: CN210107350U. The utility model discloses a steam boiler for silica sol production. The inner cavity of the boiler shell is divided into a steam chamber and a boiling water chamber. The boiling water chamber is provided with a liquid inlet pipe, and a combustion chamber is provided in the boiling water chamber. An auger shell is fixedly connected to the bottom of the combustion chamber, and an auger is provided in the inner cavity of the auger shell. An ash drop hole is provided at the connection between the combustion chamber and the auger shell. A steam outlet is provided at the top of the steam chamber. A smoke pipe is provided in the steam chamber. One end of the smoke pipe passes through a partition and is connected to the combustion chamber.

[0029] From the above description, it can be known that a boiling water chamber is formed between the partition plate 3 and the arc-shaped heat conducting plate 6, and steam is discharged to the top of each class through the steam through hole 4, and synchronously with the threaded heating smoke pipe 5 for heating.

[0030] The high-efficiency cleaning component includes an arc-shaped chute 7 symmetrically arranged in the boiler shell 1 and corresponding to the arc-shaped heat-conducting plate 6, a slider 8 is slidably arranged in the arc-shaped chute 7, a cleaning roller 9 is arranged between the sliders 8, a fixing plate 10 is arranged outside the boiler shell 1, a motor 11 is arranged on the fixing plate 10, a rope-collecting roller 12 is arranged on the output end of the motor 11, a high-temperature resistant steel cable 13 is wound around the rope-collecting roller 12, and both ends of the high-temperature resistant steel cable 13 extending into the boiler shell 1 are fixedly connected to the slider 8 close to it, and an auxiliary dust-cleaning component is arranged below the arc-shaped heat-conducting plate 6 in the boiler shell 1;
