Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection in ferrosilicon processing and production, in particular to an environmental protection filtering device for ferrosilicon processing and production. Background Art

[0002] Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made by smelting in an electric furnace using coke, steel scraps, and quartz (or silica) as raw materials. Since silicon and oxygen can easily combine to form silicon dioxide, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since a large amount of heat is released when SiO2 is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and the chemical industry. However, in the existing ferrosilicon processing and production filtering device, after the filtration is completed, ferrosilicon is easy to remain inside the device and is not easy to be discharged cleanly. In the process of filtration, the device will shake due to the need for continuous stirring, which will cause dust and the like in the raw materials to float in the air, which is not conducive to the health of the staff and affects the surrounding working environment.

[0003] After searching the existing Chinese patents: an environmentally friendly filtering device for ferrosilicon processing and production (publication number: CN216497703U), including: a filter box assembly, the filter box assembly includes a water storage tank and a filter box; the filter box is arranged inside the water storage tank; a rotating assembly, the rotating assembly includes a motor, a rotating shaft, a connecting block, a cross bar and an S-shaped rod; the output shaft of the motor is fixedly connected to the rotating shaft, and the bottom outer wall of the rotating shaft is fixedly sleeved with two connecting blocks. The piston rod of the cylinder of the utility model drives the rotating assembly and the filter box to penetrate into the water storage tank through the upper buffer assembly. At this time, the lighter and smaller materials or dust in the raw materials will be initially separated from the large particles of raw materials when they meet water. The output shaft of the motor drives the rotating shaft and the connecting block to rotate, so that the lighter and smaller materials or dust are separated from the bulk of the raw materials, and the lower buffer assembly and the upper buffer assembly cooperate to buffer the upper and lower parts to produce shaking, and the dust will not be affected by the shaking and float in the surrounding air, which is beneficial to the surrounding working environment.

[0004] Compared with the traditional environmentally friendly filtering device for ferrosilicon processing and production, the above patent reduces the shaking effect of the device through the upper and lower cooperation of the lower buffer component and the upper buffer component, and the dust will not be affected by the shaking and float in the surrounding air. However, there is no shielding or covering around the filtering device, so dust will be generated in the process of pouring ferrosilicon into the device for filtering, thus affecting the surrounding area. In addition, if the ferrosilicon raw material accidentally touches too much water during the process, it will also affect the later use of the ferrosilicon raw material, and once the ferrosilicon contacts too much water, it will react and produce a large amount of colorless and odorless toxic gas, which will endanger the health of the staff and affect the surrounding working environment.

[0005] Therefore, it is necessary to invent an environmentally friendly filtering device for ferrosilicon processing and production to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an environmentally friendly filtering device for ferrosilicon processing production to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly filtering device for ferrosilicon processing production, comprising a base plate, support rods are connected to both ends of the base plate, a connecting block is provided on the support rod, a filter box is connected to the connecting block, a hollow connecting block is provided at the rear end of the filter box, a cross bar is inserted into the interior of the hollow connecting block, a flap is inserted at both ends of the cross bar, a drive motor is installed on the flap, a rotating shaft is provided at the front end of the drive motor, the rotating shaft is connected to a connecting shaft, four sets of shaft rings are installed on the connecting shaft, and a mounting plate is installed at the front end of the filter box.

[0008] Preferably, six groups of stirring blades are mounted on the collar.

[0009] Preferably, a feed pipe is provided on one side of the driving motor.

[0010] Preferably, a vibration motor is mounted on the mounting plate.

[0012] Preferably, the filter screen is provided with a plurality of groups of sieve holes.

[0013] Preferably, a material receiving box is placed at the bottom end of the filter screen, and box handles are provided at both ends of the material receiving box.

[0014] Technical effects and advantages of the utility model:

[0015] 1. Before using the environmentally friendly filtering device for ferrosilicon processing and production, the staff of the utility model first places the material receiving box under the filter screen at the bottom of the filter box of the device in advance, and then starts the driving motor installed on the flip cover installed by the hollow connecting block and the cross bar at the rear end of the filtering device. After the driving motor is started, its front end rotating shaft will start to rotate, thereby driving the connecting shaft connected to the front end to rotate. Four sets of shaft rings are installed on the connecting shaft, and six sets of stirring blades are installed on the shaft ring, so that the stirring blades will start to rotate. At this time, the staff will pass the flip cover installed on the cross bar through the cross bar set by the hollow connecting block. The cover is flipped over and buckled on the filter box, and then the vibration motor installed on the front end of the filter box through the mounting plate is started. After the vibration motor is started, it will vibrate. Then the staff pours the ferrosilicon to be filtered into the filter box through the feed pipe provided on the flip cover. At this time, the filter box is fully stirred by the stirring blades, so that the ferrosilicon will not stick to the inside of the filter box when it is poured into the filter box for filtration. In addition, the continuous vibration of the vibration motor at the front end of the filter box will prevent the ferrosilicon from getting stuck in the filter box and being unable to be discharged.

[0016] 2. In the utility model, after the ferrosilicon enters the filter box through the feed pipe, the sieve holes on the filter net are filtered by means of vibration of a vibration motor, so as to achieve a better filtering effect more effectively. When the ferrosilicon reaches the filter net, it is vibrated by the vibration motor, so that other impurities in the ferrosilicon can be screened out under the sieve holes of the filter net, so that the ferrosilicon discharged after the final filtration will pass through the sieve holes of the filter net and fall into the receiving box placed in advance below. This device prevents dust from escaping during the production and filtering process by covering it with a flip cover, thereby ensuring that dust and the like generated by vibration and stirring of the filter device will not be discharged, and through the stirring of the stirring blades and the continuous vibration of the vibration motor, the ferrosilicon will not be discharged or stuck during discharge during the internal filtering process of the filter device, and it is not easy for residues to remain due to sufficient stirring inside the stirring blades.

[0025] Six groups of stirring blades 14 are installed on the collar 13 , wherein the collar 13 is used to install the stirring blades 14 , and the stirring blades 14 are used to stir the ferrosilicon to be filtered to prevent the ferrosilicon from remaining in the filter box 6 and sticking to the inside of the filter box 6 .

[0026] A feed pipe 17 is provided on one side of the driving motor 10, wherein the driving motor 10 is used to drive the stirring blade 14 to rotate to achieve a stirring effect. The feed pipe 17 is used for the staff to pour the ferrosilicon to be filtered into the filter box 6 through the feed pipe 17.

[0027] A vibration motor 19 is installed on the mounting plate 18, wherein the mounting plate 18 is used to install the vibration motor 19, and the vibration motor 19 is used to prevent the ferrosilicon from getting stuck in the filter box 6 through its vibration, and when the ferrosilicon reaches the filter screen 4, it is vibrated by the vibration motor 19, so that other impurities in the ferrosilicon can be screened out under the sieve hole 5 of the filter screen 4.

[0028] A filter screen 4 is installed at the lower end of the filter box 6, and fixing screws 15 are provided at the four ends of the filter screen 4. The filter screen 4 is fixed to the lower end of the filter box 6 by the fixing screws 15, wherein the filter box 6 is filled with ferrosilicon to be filtered, and the filter screen 4 is used to filter some residues and other impurities in the ferrosilicon.

[0029] The filter screen 4 is provided with a plurality of groups of sieve holes 5, wherein the volume of the sieve holes 5 is larger than the volume of the iron sand, so that some residues and other impurities in the iron sand can be filtered out.

The receiving box 16 is used to store and receive the sand iron filtered from the upper filter screen 4, and the box handles 20 are used to facilitate the staff to carry and transport the receiving box 16 when it is full.

[0031] Working principle: Before using the environmentally friendly filtering device for ferrosilicon processing and production, the staff first places the material receiving box 16 under the filter screen 4 at the bottom of the filter box 6 of the device in advance, and then starts the drive motor 10 installed on the flip cover 9 installed by the hollow connecting block 7 and the cross bar 8 at the rear end of the filtering device. After the drive motor 10 is started, its front end rotating shaft 11 will start to rotate, thereby driving the connecting shaft 12 connected to the front end to rotate. Four sets of shaft rings 13 are installed on the connecting shaft 12, and six sets of stirring blades 14 are installed on the shaft ring 13, so that the stirring blades 14 will start to rotate. At this time, the staff will use the cross bar 8 set by the hollow connecting block 7 to install the flip cover 9 installed on the cross bar 8.

[0032] When the ferrosilicon enters the filter box 6 through the feed pipe 17, the filtering of the sieve holes 5 on the filter screen 4 can be more effectively achieved by vibrating the vibration motor 19. When the ferrosilicon reaches the filter screen 4, it is vibrated by the vibration motor 19, so that other impurities in the ferrosilicon can be screened out under the sieve holes 5 of the filter screen 4. Finally, the ferrosilicon discharged after filtering will pass through the sieve holes 5 of the filter screen 4 and fall into the receiving box 16 placed in advance below. This device prevents dust from escaping during the production and filtering process by blocking with the flip cover 9, thereby ensuring that the dust generated by the vibration and stirring of the filtering device will not be discharged, and through the stirring of the stirring blades 14 and the continuous vibration of the vibration motor 19, the ferrosilicon will not be discharged or stuck during the discharge process in the filtering process of the filtering device, and the internal stirring by the stirring blades 14 will not easily leave residues.
