Description

Technical Field

[0001] This utility model relates to the technical field of magnesium sulfate production, and in particular to a magnesium sulfate raw material crushing device. Background Technology

[0002] In the production of magnesium sulfate, raw materials (such as magnesite or calcined magnesite) need to be reacted with sulfuric acid to produce magnesium sulfate. To increase the contact area between the raw materials and sulfuric acid and accelerate the reaction rate, the raw materials need to be crushed before reacting with sulfuric acid to reduce their volume and increase their surface area. In the prior art, a utility model patent with patent application number 202322104241.8 discloses a crushing device for magnesium sulfate production, which mainly consists of crushing gears, a screen, and a receiving box. During use, the raw materials are crushed by the crushing gears, and the crushed materials fall onto the screen. Qualified materials are filtered through the screen holes and enter the receiving box, while unqualified materials remain on the screen. However, this device has the following drawback: it cannot re-feed the unqualified materials separated from the screen to the crushing gears for further crushing, making it inconvenient to use and impractical. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a magnesium sulfate raw material crushing device that can not only screen the crushed raw materials, but also transport the unqualified crushed raw materials back to the crushing mechanism for crushing. It is convenient to use, practical and reliable.

[0004] This utility model discloses a magnesium sulfate raw material crushing device, comprising a base plate, a support frame, and a collection box, with the support frame and collection box both mounted on the upper part of the base plate. It also includes a screening mechanism, a crushing mechanism, a conveying mechanism, and a feeding mechanism. The conveying mechanism is mounted on the base plate, with its output end located above the collection box. The screening mechanism is mounted on the support frame, above the conveying mechanism, and functions to screen the raw material. The crushing mechanism is mounted above the screening mechanism and functions to crush the material. The feeding mechanism is mounted on the base plate and functions to feed the material. This device is used to crush magnesium sulfate raw materials. During the crushing process, the raw materials are first added to the crushing mechanism, which then crushes them. The crushed raw materials fall into the screening mechanism, which screens them. Qualified raw materials fall onto the conveying mechanism, which transports them to a collection box for storage. Unqualified raw materials are transported to the feeding mechanism, which then transports them back to the crushing mechanism for further crushing. This system not only screens the crushed raw materials but also re-feeds unqualified materials to the crushing mechanism, making it convenient, practical, and highly reliable.

[0005] Preferably, the screening mechanism includes a screen cylinder, a motor, a rotating shaft, spiral blades, and a conveying pipe. The screen cylinder is fixedly mounted on a support frame and has a chamber inside. The right end of the screen cylinder is open, and the lower part of the screen cylinder has multiple sets of screen holes communicating with the chamber. The motor is fixedly mounted on the left end of the screen cylinder, and the rotating shaft is rotatably mounted on the screen cylinder. The left end of the rotating shaft is connected to the output end of the motor. The spiral blades are fixedly mounted on the rotating shaft and are located inside the chamber of the screen cylinder. The conveying pipe is installed on the left side of the screen cylinder, with its lower end communicating with the left side of the screen cylinder chamber and its upper end connected to the crushing mechanism. The raw materials are crushed by the crushing mechanism and then fall into the left part of the screen cylinder chamber through the conveying pipe. Then, the motor is turned on, and the motor drives the rotating shaft and the spiral blades to rotate. During the rotation of the spiral blades, the raw materials in the screen cylinder chamber are conveyed to the right. During the rightward conveying process, the crushed raw materials will gradually be discharged through multiple screen holes at the bottom of the screen cylinder and fall onto the conveying mechanism. The raw materials that do not meet the size requirements are pushed by the spiral blades to the opening at the right end of the screen cylinder chamber. Then, the unqualified raw materials fall into the conveying mechanism through the opening at the right end of the screen cylinder and are then conveyed. This facilitates the screening of raw materials.

[0006] Preferably, the crushing mechanism includes a support plate, a crushing cylinder, a feeding funnel, and a crushing mechanism. The crushing cylinder is fixedly installed on the upper end of the screen cylinder via the support plate. The crushing cylinder is installed at an incline on the support plate, with the left end lower and the right end higher. A cavity is provided inside the crushing cylinder. The feeding funnel is installed on the right side of the crushing cylinder and communicates with the cavity of the crushing cylinder. The upper end of the conveying pipe communicates with the left side of the cavity of the crushing cylinder. The crushing mechanism is installed on the crushing cylinder and has the function of crushing raw materials. When crushing raw materials, the raw materials are added into the cavity of the crushing cylinder through the feeding funnel, and the crushing mechanism is opened at the same time. The raw materials are crushed by the crushing mechanism as they slide to the left in the cavity of the crushing cylinder. The crushed raw materials slide into the screen cylinder through the conveying pipe for sieving. This facilitates the crushing of raw materials and increases the surface area of ​​the raw materials.

[0007] Preferably, the crushing mechanism includes a drive motor, a rotating shaft, and multiple crushing blades. The drive motor is fixedly installed at the left end of the crushing cylinder, the rotating shaft is rotatably installed on the crushing cylinder, and the left end of the rotating shaft is connected to the output end of the drive motor. The multiple crushing blades are all fixedly installed on the rotating shaft and are located inside the cavity of the crushing cylinder. When the raw material is added into the cavity of the crushing cylinder, the drive motor is turned on, and the drive motor drives the rotating shaft and the multiple crushing blades to rotate. The rotating multiple crushing blades crush the raw material in the cavity of the crushing cylinder, which facilitates the crushing of the raw material.

[0008] Preferably, the conveying mechanism includes a belt conveyor mounted on a base plate, with a conveyor belt positioned below the screen cylinder. When the raw material is conveyed and screened in the screen cylinder, qualified raw material falls onto the conveyor belt through multiple screen holes at the bottom of the screen cylinder. Then, the belt conveyor is turned on to convey the raw material on the conveyor belt to the left, and the raw material falls into the collection box through the left end of the conveyor belt for collection. This facilitates the conveying of qualified raw material.

[0009] Preferably, the conveying mechanism includes a transfer cylinder and a moving mechanism. The transfer cylinder has a transfer chamber and an open upper end. The transfer cylinder is located below the right end of the screen cylinder. A discharge funnel communicating with the transfer chamber is located below the transfer cylinder. A valve is installed on the discharge funnel. The transfer cylinder is mounted on the moving mechanism, which is used to move the transfer cylinder. After the crushed raw material is screened in the screen cylinder, the unqualified raw material is pushed into the transfer cylinder by the rotating spiral blades through the opening at the right end of the screen cylinder. Then, the moving mechanism is opened to move the transfer cylinder above the feed funnel. Then, the valve on the discharge funnel is opened to allow the raw material in the transfer cylinder to fall into the feed funnel through the discharge funnel. The unqualified raw material then re-enters the crushing cylinder through the feed funnel for crushing. This facilitates the transfer of unqualified raw materials.

[0010] Preferably, the moving mechanism includes a sliding block, an electric slide rail A, an electric slide rail B, a lifting block, and a connecting plate. Electric slide rail A is mounted on a base plate, and the sliding block is mounted on electric slide rail A. Electric slide rail A is used to move the sliding block left and right. Electric slide rail B is fixedly mounted on the upper end of the sliding block, and the lifting block is mounted on electric slide rail B. Electric slide rail B is used to adjust the height of the lifting block. The transfer cylinder is fixedly mounted on the lifting block via the connecting plate. When moving the transfer cylinder, opening electric slide rail A allows electric slide rail A to move the lifting block, connecting plate, and transfer cylinder left and right via the sliding block. Opening electric slide rail B allows the lifting block to adjust its height, and the lifting block adjusts the height of the connecting plate and transfer cylinder. Therefore, the transfer cylinder can move left and right and its height can be adjusted, facilitating its movement.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only screen the crushed raw materials, but also transport the unqualified crushed raw materials back to the crushing mechanism for crushing. It is convenient to use and has high practicality and reliability. Attached Figure Description

The screening mechanism is installed on the support frame 2, located above the conveying mechanism, and functions to screen the raw material. The crushing mechanism is installed above the screening mechanism and functions to crush the material. The feeding mechanism is installed on the base plate 1 and functions to feed the material. This device is used for crushing magnesium sulfate raw materials. When the material is being crushed, it is first added to the crushing mechanism, which then crushes it. The crushed material falls into the screening mechanism, which screens it. Qualified material falls onto the conveying mechanism, which transports it to the collection box 3 for storage. Unqualified material is transported to the feeding mechanism, which then transports it back to the crushing mechanism for further crushing. This system not only screens the crushed material but also re-feeds unqualified material to the crushing mechanism, making it convenient, practical, and highly reliable.

[0016] like Figure 1 , Figure 2 and Figure 5The screening mechanism includes a screen cylinder 4, a motor 5, a rotating shaft 6, a spiral blade 7, and a conveying pipe 8. The screen cylinder 4 is fixedly mounted on a support frame 2. A chamber is provided inside the screen cylinder 4, with an opening at the right end.

The conveying pipe 8 is installed on the left side of the screen cylinder 4, with its lower end communicating with the left side of the chamber and its upper end communicating with the powder. The crushing mechanism is connected; after the raw material is crushed by the crushing mechanism, it falls into the left part of the chamber of the screen cylinder 4 through the conveying pipe 8. Then, the motor 5 is turned on, and the motor 5 drives the rotating shaft 6 and the spiral blade 7 to rotate. During the rotation, the spiral blade 7 conveys the raw material in the chamber of the screen cylinder 4 to the right. During the process of conveying the raw material to the right, the crushed and qualified raw material will gradually be discharged through multiple screen holes at the bottom of the screen cylinder 4 and fall onto the conveying mechanism. The unqualified raw material is pushed by the spiral blade 7 to the opening at the right end of the chamber of the screen cylinder 4. Then, the unqualified raw material falls into the conveying mechanism through the opening at the right end of the screen cylinder 4 and can be conveyed. This facilitates the screening of raw materials.

[0017] like Figure 1 and Figure 4 The crushing mechanism includes a support plate 9, a crushing cylinder 10, a feeding funnel 11, and a crushing mechanism. The crushing cylinder 10 is fixedly installed on the upper end of the screen cylinder 4 via the support plate 9.

The upper end of the conveying pipe 8 communicates with the left side of the cavity of the crushing cylinder 10. The crushing mechanism is installed on the crushing cylinder 10 and has the function of crushing raw materials. When crushing raw materials, the raw materials are added into the cavity of the crushing cylinder 10 through the feeding funnel 11, and the crushing mechanism is opened at the same time. The raw materials are crushed by the crushing mechanism as they slide to the left in the cavity of the crushing cylinder 10. The crushed raw materials slide into the screen cylinder 4 through the conveying pipe 8 for sieving. This facilitates the crushing of raw materials and increases the surface area of ​​the raw materials.

[0018] like Figure 4 The crushing mechanism includes a drive motor 12, a rotating shaft 13, and multiple crushing blades 14. The drive motor 12 is fixedly installed on the left end of the crushing cylinder 10, and the rotating shaft 13 is rotatably installed on the crushing cylinder 10. The left end of the rotating shaft 13 is connected to the output end of the drive motor 12. The multiple crushing blades 14 are all fixedly installed on the rotating shaft 13 and are located inside the cavity of the crushing cylinder 10. When the raw material is added into the cavity of the crushing cylinder 10, the drive motor 12 is turned on. The drive motor 12 drives the rotating shaft 13 and the multiple crushing blades 14 to rotate. The rotating multiple crushing blades 14 crush the raw material in the cavity of the crushing cylinder 10, which facilitates the crushing of the raw material.

[0019] like Figure 1 The conveying mechanism includes a belt conveyor 15, which is mounted on a base plate 1. A conveyor belt 16 is installed on the belt conveyor 15 and is located below the screen cylinder 4. When the raw material is conveyed and screened in the screen cylinder 4, qualified raw material falls onto the conveyor belt 16 through multiple screen holes at the bottom of the screen cylinder 4. Then, the belt conveyor 15 is turned on to convey the raw material on the conveyor belt 16 to the left. The raw material then falls into the collection box 3 through the left end of the conveyor belt 16 for collection. This facilitates the conveying of qualified raw materials.

[0020] like Figure 1 The conveying mechanism includes a transfer cylinder 17 and a moving mechanism. The transfer cylinder 17 has a transfer chamber inside and an open upper end. The transfer cylinder 17 is located below the right end of the screen cylinder 4. A discharge funnel 18 communicating with the transfer chamber is located below the transfer cylinder 17. A valve is installed on the discharge funnel 18. The transfer cylinder 17 is mounted on the moving mechanism, which is used to move the transfer cylinder 17. After the crushed raw material is screened in the screen cylinder 4, the unqualified raw material is pushed into the transfer cylinder 17 by the rotating spiral blades 7 through the opening at the right end of the screen cylinder 4. Then, the moving mechanism is opened to move the transfer cylinder 17 above the feed funnel 11. Then, the valve on the discharge funnel 18 is opened, allowing the raw material in the transfer cylinder 17 to fall into the feed funnel 11 through the discharge funnel 18. After that, the unqualified raw material re-enters the crushing cylinder 10 through the feed funnel 11 for crushing. This facilitates the transfer of unqualified raw materials.

The electric slide rail B21 is used to adjust the height of the lifting block 22. The transfer cylinder 17 is fixed via the connecting plate 23. The electric slide rail A20 is fixedly installed on the lifting block 22. When the transfer cylinder 17 is moved, the electric slide rail A20 is opened. The electric slide rail A20, through the sliding block 19, can cause the electric slide rail B21 to drive the lifting block 22, the connecting plate 23 and the transfer cylinder 17 to move left and right. The electric slide rail B21 is opened, and the electric slide rail B21 drives the lifting block 22 to adjust the height. The lifting block 22 drives the connecting plate 23 and the transfer cylinder 17 to adjust the height. Therefore, the transfer cylinder 17 can move left and right and adjust its height, which facilitates the movement of the transfer cylinder 17.

[0022] Example 2 Based on Example 1, rubber baffles are provided at both the front and rear ends of the conveyor belt 16; through the above-mentioned arrangement, the raw materials are prevented from falling through the front and rear ends of the conveyor belt 16, thereby improving the reliability during use.
