Description

Technical Field

[0001] The utility model relates to the technical field of sodium carbonate processing weighing equipment, in particular to an automatic weighing equipment for sodium carbonate raw materials. Background Art

[0002] Sodium silicate is also known as sodium silicate. Its aqueous solution is called water glass. It is a colorless, turquoise or brown solid or viscous liquid. Sodium silicate is made by melting silica (quartz sand) and soda ash (or earth soda) in a melting furnace, cooling and crushing. Its fuel can be coal, natural gas, or coal gas. The raw materials for producing sodium silicate are quartz sand and soda ash. The two are mixed in a certain proportion and sent to a reverberatory kiln. After high-temperature calcination and water quenching in a melting furnace, they are packaged to form solid sodium silicate. Solid sodium silicate is easy to transport and store. Liquid sodium silicate is obtained by dissolving solid sodium silicate into liquid at a certain temperature and pressure. It needs to be weighed during the production process of sodium silicate.

[0003] After searching, the patent with announcement number CN217818966U discloses a metering weighing device for sodium carbonate processing, which belongs to the technical field of sodium carbonate processing equipment, including a base, a fixed frame, a feeding port, a driving device, a collecting device and a weighing device. The base is horizontally arranged, the fixed frame is arranged on the base, the feeding port is arranged on the fixed frame, the driving device is arranged on the base, the collecting device is arranged above the driving device, and the weighing device is arranged on the driving device. The weighing device includes a weighing assembly and a telescopic hydraulic cylinder, the weighing assembly is arranged below the feeding port, and the telescopic hydraulic cylinder is arranged on the weighing assembly. This device can adjust the different weighing required for sodium carbonate, and can achieve the effect of quantitative unloading of the adjusted product weight.

[0004] The technical solution has the following problems:

[0005] Although the sodium silicate raw material can be weighed, when the silica (quartz sand) raw material needs to be weighed, the silica cannot be crushed. When adding silica to the feed port, due to the different sizes of silica, the silica is easy to get stuck in the feed port, which is easy to cause blockage and is inconvenient. Utility Model Content

[0006] The purpose of the utility model is to solve the problems in the prior art that although the raw material of sodium silicate can be weighed, when the silica (quartz sand) raw material needs to be weighed, the silica cannot be crushed, and when the silica is added to the feeding port, due to the different sizes of the silica, the silica is easy to get stuck in the feeding port, which is easy to cause blockage and is relatively inconvenient. An automatic weighing device for sodium silicate raw material is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] The crushing mechanism is arranged on the L plate and is used for crushing silica.

[0010] In a possible design, the crushing mechanism includes two rotating rods, two crushing rollers, two gears, a special-shaped frame, a crushing bucket and a motor. L frames are welded on both sides of the crushing bucket, and the bottom ends of the two L frames are welded to the top of the L plate. Two bearings are embedded in one side of the crushing bucket. The outer sides of the two rotating rods are fixedly connected to the inner walls of the inner rings of the two bearings, and one end of the two rotating rods is rotatably connected to the inner wall of one side of the crushing bucket. The two crushing rollers are fixedly mounted on the two rotating rods, and the two gears are fixedly mounted on the two rotating rods. One side of the special-shaped frame is welded to one side of the crushing bucket. The bottom of the motor is fixedly connected to the bottom inner wall of the special-shaped frame. The output end of the motor is fixedly connected to one end of one of the rotating rods, and the two gears are meshed. Guide plates are welded to the inner walls of both sides of the crushing bucket.

When the weighing bucket is subjected to gravity, the weighing bucket will slide up and down in the circular hole of the L plate, and the weighing bucket presses down the weighing sensor, so that the value of the weighing sensor changes. The silica raw material of sodium silicate is automatically weighed by the weighing sensor. When the specified weight is reached, the weighing bucket is opened by the electromagnetic valve, and then the outlet at the bottom of the weighing bucket is discharged. The protective cover can prevent the gears and motors from being exposed to the outside, protect the staff, and improve safety. The heat dissipation holes can facilitate ventilation in the protective cover, which is beneficial to the heat dissipation of the motor. The connection between the motor and the rotating rod can be connected by a coupling.
