Description

Technical Field

[0001] The utility model belongs to the technical field of ferroalloy production, and particularly relates to a high-purity silicon ferrosilicon thermal strength crushing device. Background Technique

[0002] Ferrosilicon is an iron-silicon alloy smelted in an electric furnace with coke, steel scrap, quartz (or silica) as raw materials. It is often used as a deoxidizer in steelmaking and can also be used as an alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is commonly used as a reducing agent in ferroalloy production and chemical industry. According to the requirements of smelting process, the ferrosilicon alloy must ensure a certain particle size (lump size). Too large or too small lumps are not conducive to metallurgical production.

[0003] At present, in the process of ferrosilicon casting production, ferrosilicon molten iron first needs to be cast in an ingot mold to cool and form ferrosilicon ingots, and then the ferrosilicon ingots are broken according to actual needs. The main ways of breaking ferrosilicon ingots are two ways: crushing by jaw crusher and manual crushing. Although crushing by jaw crusher has higher efficiency, the qualified rate of the crushed lumps produced is lower and there are more wastes; although manual knocking and crushing can ensure the required crushing particle size (lump size) of users and has a high qualified rate, the crushing operation efficiency is low and the labor intensity is high. Content of the Utility Model

[0004] The utility model aims at the problems existing in the prior art in the above background technique, and provides a high-purity silicon ferrosilicon thermal strength crushing device. When using this device, ferrosilicon molten iron does not need to be cast in an ingot mold, cooled and then broken. Instead, it is directly forced to cool in this device and quickly solidify into a shape, and then vibrated and broken to obtain ferrosilicon fragments.

[0005] In order to achieve the above purposes, the content of the utility model adopts the following technical scheme:

[0006] A high-purity silicon ferrosilicon thermal strength crushing device, including a frame, a cooling and crushing tank, a main water inlet pipe, and a main water outlet pipe.

The main water inlet pipe and the main water outlet pipe are respectively fixed to the supports through U-shaped pipe clamps. A vibration mechanism is arranged at the bottom of the cooling and crushing tank, and a driving mechanism for driving the vibration mechanism to generate vibration is arranged on one side of the vibration mechanism.

[0007] Further, the vibration mechanism includes a housing, in which a driving shaft, a first driven shaft and a second driven shaft are rotatably installed. At the middle positions of the shafts of the driving shaft, the first driven shaft and the second driven shaft, a driving gear, a first driven gear and a second driven gear are respectively installed. The first driven gear and the second driven gear are both engaged with the driving gear. Two first eccentric blocks symmetrical about the first driven gear are further provided on the first driven shaft, and two second eccentric blocks symmetrical about the second driven gear are further provided on the second driven shaft.

[0008] Further, the cooling cavity is divided into a plurality of cooling chambers by a plurality of partitions arranged at equal intervals. Each cooling chamber is communicated with the water inlet main pipe through a water inlet branch pipe, and each cooling chamber is communicated with the water outlet main pipe through a water outlet branch pipe.

[0009] Further, the driving mechanism includes a driving motor, which is installed on an independently arranged bracket. The output shaft of the driving motor is coaxially connected with the driving shaft through a flexible coupling.

[0010] Further, the upper surface of the bottom plate of the cooling and crushing tank is inclined. The inclined upper end is the casting end of ferrosilicon molten iron, and the inclined lower end is the discharging end of ferrosilicon fragments.

[0011] Further, a baffle is provided at the casting end of ferrosilicon molten iron of the cooling and crushing tank.

Specific embodiments

[0022] In order to make the purpose, technical solution and advantages of the utility model content clearer, the following further details the utility model content in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model content and are not used to limit the utility model content.

[0023] A high-purity silicon ferrosilicon thermal strength crushing device includes a frame 1, a cooling crushing tank 3, a main water inlet pipe 9, and a main water outlet pipe 10. A plurality of supports 4 are symmetrically arranged on the left and right side plates of the cooling crushing tank 3. Springs 2 are arranged between the supports 4 and the frame 1. A cooling cavity is left inside the cooling crushing tank 3, and the cooling cavity is respectively communicated with the main water inlet pipe 9 and the main water outlet pipe 10. The main water inlet pipe 9 and the main water outlet pipe 10 are respectively fixed to the supports 4 through U-shaped pipe clamps. A vibration mechanism 8 is arranged at the bottom of the cooling crushing tank 3, and a driving mechanism for driving the vibration mechanism 8 to generate vibration is arranged on one side of the vibration mechanism 8.

[0024] Specifically, the vibration mechanism 8 includes a housing 801. Inside the housing 801, a driving shaft, a first driven shaft, and a second driven shaft are rotatably installed. At the middle positions of the shafts of the driving shaft, the first driven shaft, and the second driven shaft, a driving gear 802, a first driven gear 803, and a second driven gear 804 are respectively installed. Both the first driven gear 803 and the second driven gear 804 are engaged with the driving gear 802. There are also two first eccentric blocks 805 symmetrically arranged with respect to the first driven gear 803 on the first driven shaft, and two second eccentric blocks 806 symmetrically arranged with respect to the second driven gear 804 on the second driven shaft. The driving mechanism includes a driving motor 5. The driving motor 5 is installed on a separately provided bracket 7. The output shaft of the driving motor 5 is coaxially connected to the driving shaft through a flexible coupling 6. The first eccentric blocks 805 and the second eccentric blocks 806 rotate in the same direction as the rotation of the first driven shaft and the second driven shaft that rotate in the same direction, generating centrifugal force. Under the action of the centrifugal force, a vibration force is generated, thereby driving the cooling and crushing tank 3 fixedly connected to the housing to vibrate.

[0025] Specifically, in order to improve the cooling effect of the cooling and crushing tank 3, the cooling cavity is divided into a number of cooling chambers by a number of partition plates 14 arranged at equal intervals. Each cooling chamber is communicated with the water inlet main pipe 9 through a water inlet branch pipe 11, and each cooling chamber is communicated with the water outlet main pipe 10 through a water outlet branch pipe 12. The water inlet main pipe 9 is externally connected to a water source. Water from the water source is injected into the water inlet main pipe 9 through a water supply pump, and is split into the cooling chambers through a number of water inlet branch pipes 11, and then flows out through the corresponding water outlet branch pipes 12.

[0026] Specifically, in order to improve the fluidity of ferrosilicon molten iron for rapid cooling and the export of ferrosilicon fragments, the upper surface of the bottom plate of the cooling and crushing tank 3 is inclined. The inclined upper end is the pouring end of ferrosilicon molten iron, and the inclined lower end is the export end of ferrosilicon fragments.

[0027] Specifically, in order to reduce or avoid the splashing of molten iron out of the cooling and crushing tank 3 during the pouring of ferrosilicon molten iron, a baffle 13 is provided at the pouring end of ferrosilicon molten iron of the cooling and crushing tank 3.

[0028] The working principle of a high-purity silicon ferrosilicon thermal strength crushing device of the present utility model: The molten ferrosilicon molten iron in the pouring ladle is poured towards the pouring end of ferrosilicon molten iron of the cooling and crushing tank. The molten iron is quickly solidified and formed after water cooling in the cooling and crushing tank. The solidified ferrosilicon alloy is very brittle and is vibrationally crushed in the vibrating cooling and crushing tank, and is exported from the export end of ferrosilicon fragments to obtain ferrosilicon alloy fragments.
