Description

Technical Field

[0001] This utility model relates to the field of olivine porous tundish dry material production technology, specifically to an olivine porous tundish dry material raw material crushing device. Background Technology

[0002] Olivine porous tundish dry refractory is a high-quality refractory material specifically designed for steelmaking tundishes. It is made primarily from olivine, combined with various additives and binders, through a special process. This material not only possesses excellent refractoriness and erosion resistance but also effectively prevents molten steel penetration, ensuring the safe operation of the tundish. Simultaneously, its porous structure enhances thermal stability and service life. Construction is simple and quick, making it an indispensable material in steelmaking production. The production of olivine porous tundish dry refractory requires the use of a raw material crushing device, which ensures the uniformity and fineness of the raw materials, providing a high-quality raw material base for subsequent mixing, forming, and other processes.

[0003] Chinese Patent CN211514658U discloses an environmentally friendly refractory material raw material crushing device, including a shell with a feed hopper connected to the top of the shell. Two crushing rollers are provided at the top of the inner cavity of the shell, and a collecting cylinder is provided below the crushing rollers. A guide pipe is connected to the bottom of the collecting cylinder. A crushing cylinder is provided at the bottom of the inner cavity of the shell. The crushing cylinder has sieve holes and a rotating shaft is coaxially provided inside the crushing cylinder. A crushing rod is provided on the rotating shaft. Cover plates are rotatably connected to both ends of the crushing cylinder through external bearings. One end of the guide pipe is connected to the inner cavity of the crushing cylinder. A drive shaft is provided below the crushing cylinder. The middle part of the drive shaft is connected to the crushing cylinder and the end is connected to the rotating shaft.

[0004] While the above solutions have solved the problem of screen clogging and improved material crushing efficiency, the raw material for the porous tundish dry olivine material is mainly olivine. Large pieces of olivine material are difficult to crush effectively in a single operation. At the same time, dust is easily generated during crushing, which can escape from the feed inlet, thus polluting the working environment and endangering the health of operators. Therefore, it does not meet the current requirements. In response, we propose a raw material crushing device for the porous tundish dry olivine material. Utility Model Content

[0005] The purpose of this invention is to provide a raw material crushing device for porous tundish dry olivine material, in order to solve the problems of insufficient crushing effect of raw material crushing devices for porous olivine tundish dry olivine material and easy generation of dust pollution that harms the working environment and health of operators.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a porous intermediate dry material crushing device for olivine, comprising a main body, a crushing chamber inside the main body, a sieve plate inside the crushing chamber, a first rotating door installed on the lower side of the front end of the main body, and a second rotating door installed on one side of the front end of the main body;

[0007] It also includes a return chamber, which is opened on one side inside the main body and is connected to the crushing chamber. A spiral conveying rod is rotatably arranged inside the return chamber.

[0008] It also includes a dust collection chamber, which is located on one side inside the main body. The dust collection chamber has three equidistant dustproof nets. An annular seat is located at the middle of the upper end of the main body. The inner wall of the annular seat has several dust suction holes arranged in a rectangular array. The upper end of the annular seat has a feed inlet. The annular seat and the dust collection chamber are connected by a connecting pipe.

[0009] Preferably, a transmission cavity is provided on one side of the crushing chamber, and two crushing rollers are rotatably arranged on the upper side inside the crushing chamber. One end of each crushing roller extends into the interior of the transmission cavity, and a transmission gear is provided on the outer wall of the end of each crushing roller located inside the transmission cavity, and the transmission gears are meshed together.

[0010] Preferably, a second motor is provided on one side inside the transmission cavity, and the output end of the second motor is connected to one of the crushing rollers via a coupling.

[0011] Preferably, a first motor is provided below the return chamber, and the output end of the first motor is connected to the screw conveyor rod via a coupling.

[0012] Preferably, an air suction machine is provided below the dust collection chamber, and the air suction machine is connected to the dust collection chamber.

[0013] Preferably, a collection box is provided on the lower side of the inside of the crushing chamber, and rollers are installed at the four corners of the lower end of the collection box.

[0014] Preferably, a vibration motor is installed on one side of the lower end of the screening plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model has a return chamber on one side inside the main body. After the raw material is crushed, it will be screened by the screening plate. The unqualified raw material will enter the return chamber. By starting the first motor, the screw conveyor can be rotated, so that the unqualified raw material can be conveyed and fall from above the crushing roller again, and then crushed a second or even multiple times. This can achieve thorough crushing and ensure that the final raw material meets the production requirements.

[0017] 2. This utility model features an annular seat at the upper end of the main body. When crushing is performed, the suction machine is activated, drawing air out of the dust collection chamber. This suction force, generated by the connecting pipe, allows the dust produced during crushing to be drawn into the annular seat through the suction hole. The connecting pipe then allows the dust to enter the dust collection chamber, where it is intercepted by a dustproof net. The dust is then collected in the dust collection chamber. Operators can clean the dust by periodically opening the second rotating door, thus preventing dust from escaping from the feed inlet during crushing, avoiding environmental pollution, and ensuring the health of the operators.

[0018] 3. This utility model has a collection box at the lower end of the crushing chamber. The raw materials that pass the screening plate will fall directly into the collection box. The operator can easily remove the collection box by opening the first rotating door and rolling the rollers, thereby avoiding the blockage during material discharge, realizing rapid material discharge and facilitating the crushing operation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a olivine porous intermediate dry material crushing device, including a main body 1, a crushing chamber 6 is provided inside the main body 1, a sieve plate 7 is provided inside the crushing chamber 6, a first rotating door 19 is installed on the lower side of the front end of the main body 1, and a second rotating door 20 is installed on one side of the front end of the main body 1.

[0027] It also includes a return chamber 11, which is opened on one side inside the main body 1 and is connected to the crushing chamber 6. A spiral conveying rod 10 is rotatably arranged inside the return chamber 11.

[0028] It also includes a dust collection chamber 16, which is located on one side inside the main body 1. The dust collection chamber 16 has three equidistant dustproof nets 17. An annular seat 3 is located at the middle position of the upper end of the main body 1. The inner wall of the annular seat 3 has several dust suction holes 4 arranged in a rectangular array. The upper end of the annular seat 3 has a feed inlet 2. The annular seat 3 and the dust collection chamber 16 are connected by a connecting pipe 5.

[0029] In use, raw materials are added to the crushing chamber 6 through the feed inlet 2. The second motor 22 drives the crushing roller 21 to rotate synchronously for crushing. After screening by the screening plate 7, the vibrating motor 8 enhances the screening effect. Unqualified raw materials are sent back to the screw conveyor 10 through the return chamber 11 for further crushing. During crushing, the air suction machine 18 draws air from the annular seat 3 through the dust suction hole 4 and the connecting pipe 5 to form a negative pressure, collecting dust into the dust collection chamber 16. The dustproof net 17 intercepts the dust. Qualified raw materials fall into the collection box 12 and are easily removed and accurately reset through the cooperation of the roller 13 and the guide block 14 with the guide groove 15.

[0030] Please see Figure 2 and Figure 3 A transmission chamber 24 is provided on one side of the crushing chamber 6. Two crushing rollers 21 are rotatably arranged on the upper side inside the crushing chamber 6. One end of each crushing roller 21 extends into the interior of the transmission chamber 24. A transmission gear 23 is provided on the outer wall of the end of the crushing roller 21 inside the transmission chamber 24. The transmission gears 23 are meshed and connected to each other. The meshing connection of the transmission gears 23 ensures that the two crushing rollers 21 can rotate synchronously, which improves the uniformity and efficiency of crushing.

[0031] Please see Figure 2 A second motor 22 is installed on one side inside the transmission cavity 24. The output end of the second motor 22 is connected to one of the crushing rollers 21 through a coupling. The second motor 22 serves as a power source and directly drives one of the crushing rollers 21 to rotate through the coupling. Then, through the meshing action of the transmission gear 23, it drives the other crushing roller 21 to rotate synchronously, thus realizing efficient power transmission, simplifying the transmission structure, and improving the reliability and stability of the equipment.

[0032] Please see Figure 2 A first motor 9 is installed below the return chamber 11, and the output end of the first motor 9 is connected to the screw conveyor 10 through a coupling. The first motor 9 can accurately control the speed and direction of the screw conveyor 10, thereby achieving accurate conveying of unqualified raw materials. The design of the screw conveyor 10 ensures the stability and continuity of the raw materials during the conveying process, avoiding the accumulation and blockage of raw materials.

[0033] Please see Figure 2 A suction machine 18 is installed below the dust collection chamber 16 and is connected to the dust collection chamber 16. The suction machine 18 can generate a strong suction force to suck the dust generated during the crushing process into the dust collection chamber 16 through the dust suction hole 4, effectively preventing the spread and pollution of dust.

[0034] Please see Figure 2 and Figure 4 A collection box 12 is provided on the lower side inside the crushing chamber 6. Rollers 13 are installed at the four corners of the lower end of the collection box 12. Guide blocks 14 are glued and fixed on both sides of the collection box 12. Guide grooves 15 are opened on the lower side of both sides inside the crushing chamber 6, and the guide grooves 15 slide with the guide blocks 14. The design of the collection box 12 facilitates the collection and removal of qualified raw materials. The addition of rollers 13 makes the movement of the collection box 12 easier and more convenient, reducing the labor intensity of operators. The sliding cooperation between the guide blocks 14 and the guide grooves 15 ensures the stability and accuracy of the collection box 12 during the movement, avoiding the spillage of raw materials or equipment damage caused by positional deviation.

[0035] Please see Figure 2A vibration motor 8 is installed on one side of the lower end of the screening plate 7. The vibration motor 8 can generate continuous vibration force, which acts on the screening plate 7, causing the raw material on the screening plate 7 to be shaken and impacted, thereby improving the screening efficiency and effect. Vibration can also effectively prevent the raw material from clogging or agglomerating on the screening plate 7, ensuring the continuity and stability of screening.

[0036] Working principle: During use, the raw material of porous olivine intermediate bag dry material is added into the crushing chamber 6 through the feed inlet 2. The second motor 22 is started, and the second motor 22 causes one of the crushing rollers 21 to rotate through the coupling. The meshing connection between the transmission gears 23 allows the two crushing rollers 21 to rotate synchronously, thereby crushing the falling raw material. The crushed raw material falls onto the screening plate 7 and passes through the screening plate 7. The raw materials can be screened. Starting the vibrating motor 8 improves the screening effect and prevents material blockage in the screening plate 7. Unqualified materials slide into the return chamber 11 during vibration. Starting the first motor 9, which drives the screw conveyor 10 via a coupling, allows the unqualified materials to be conveyed upwards to the two crushing rollers 21 for further crushing, ensuring more thorough and effective crushing. During crushing, the suction machine 18 is activated, extracting air from the dust collection chamber 16. Through the connecting pipe 5, air can be extracted from the annular seat 3, creating negative pressure and suction to remove the powder produced during crushing. Dust is drawn into the interior through the suction hole 4, and then enters the dust collection chamber 16 through the connecting pipe 5. Finally, the dust is intercepted by the dustproof net 17 and collected inside the dust collection chamber 16. The operator can clean the dust by opening the second rotating door 20, thus avoiding pollution of the working environment and ensuring the health of the operator. The crushed raw materials will fall into the collection box 12. The operator can easily move the collection box 12 out of the crushing chamber by opening the first rotating door 19 and rolling the roller 13, making the discharge more convenient. At the same time, the guide blocks 14 and guide grooves 15 on both sides of the collection box 12 can prevent the collection box 12 from shifting its position when it is reset, making it convenient to use.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
