Description

Technical Field

[0001] This utility model relates to the field of gypsum preparation equipment, and more particularly to a raw material preparation equipment. Background Technology

[0002] Gypsum specifically refers to a mineral belonging to the monoclinic crystal system. Its main component is calcium sulfate hydrate. It is favored as a widely used industrial and building material. Phosphogypsum is a solid waste produced in the wet phosphoric acid process, which contains unreacted phosphorus. Roadbed phosphogypsum is a new type of roadbed material with phosphogypsum as the main raw material. It is made by calcining phosphogypsum and mixing it evenly with materials such as gravel and special building adhesive powder. This process requires the use of professional material preparation equipment.

[0003] In current material preparation equipment, all raw materials are usually added into the device at once and mixed directly using a stirring rod. However, when all raw materials are poured in, the amount of raw materials in the device often becomes quite large. This may make it more difficult for the stirring rod to mix a large amount of raw materials at once, and may also prolong the mixing time, thereby reducing the preparation efficiency and quality of roadbed phosphogypsum. In addition, the calcined gypsum may still contain large particles, which are often difficult to crush during the mixing process. This may have an adverse effect on the mixing results, and thus may affect the overall quality of roadbed phosphogypsum.

[0004] Therefore, those skilled in the art have provided a raw material preparation apparatus to solve the problems mentioned in the background art. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A raw material preparation device includes a stirring mechanism, and a feeding mechanism is provided at the upper end of the stirring mechanism;

[0008] The mixing mechanism includes a mixing frame, a vibrating plate, and two scrapers. Mixing rollers are rotatably mounted on both sides of the mixing frame.

A turning roller is rotatably fitted on the inner surface of the storage frame. Multiple slots are opened near the front and rear ends of the upper end of the storage frame. Multiple partition plates are fitted on the body of the connecting rod. Two rolling rollers are rotatably fitted on the inner surface of the middle frame.

[0010] Furthermore, a No. 1 motor is fixedly connected to the front end of the stirring roller, and the No. 1 motor is fixedly installed at the front end of the stirring frame. Both scrapers are located above the screen, and the two ends of the two scrapers are slidably sleeved on the two horizontal sliding rods respectively.

[0011] Furthermore, the vibrating plate is slidably disposed in the stirring frame, the vibrating plate is located between two vertical plates, the vibrating plate is located at the lower end of two vibration motors, and the lower end of the vibrating plate is fixedly connected to the upper end of multiple springs.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model proposes a raw material preparation device, which includes a stirring mechanism. During use, the vibrating plate and the screen play important roles. A vibrating motor is installed above the vibrating plate, and a spring is installed below it. This ensures the up-and-down vibration of the vibrating plate and reduces the interference of vibration on the stirring frame. Under the action of vibration, the screen can evenly sieve the raw materials into the lower part. At the same time, the L-shaped rod can reciprocate along the V-shaped chute, thereby driving the scraper to reciprocate along the screen direction, evenly spreading the raw materials on the screen and ensuring the screening rate. This allows for the slow and even addition of various raw materials while simultaneously turning and stirring, reducing the difficulty of stirring and thus ensuring the preparation efficiency and quality of roadbed phosphogypsum.

During use, the partition plate can move horizontally along the connecting rod and its position can be adjusted according to the actual ratio of the raw materials. The slot can fix the position of the partition plate. This design allows for direct ratioing of raw materials, greatly simplifying the feeding process. At the same time, the storage box can guide the raw materials to the middle position of the two rolling rollers for effective rolling and crushing. This ensures the fineness of the raw material particles, which facilitates subsequent mixing operations and guarantees the quality of the roadbed phosphogypsum. Attached Figure Description

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.

[0028] Reference Figure 1 One embodiment of this utility model is a raw material preparation device, including a stirring mechanism 1, and a feeding mechanism 2 is provided at the upper end of the stirring mechanism 1.

[0029] Specifically, the mixing mechanism 1 can mix various raw materials and, in conjunction with the feeding mechanism 2, slowly pours the raw materials into the bottom of the mixing frame 101 through the screen 110. Adding materials while mixing can improve the efficiency and quality of mixing. The feeding mechanism 2 can crush and filter the raw materials to ensure the quality of the roadbed phosphogypsum and can also roughly control the proportion of raw materials, making it convenient to operate.

[0030] Reference Figure 4 , Figure 5 The mixing mechanism 1 includes a mixing frame 101, a vibrating plate 109, and two scrapers 112. Mixing rollers 102 are rotatably sleeved on both sides of the mixing frame 101. A discharge gate 103 is slidably arranged near the lower end of the mixing frame 101. Vibrating motors 104 are fixedly arranged at the front and rear ends near the upper end of the inner surface of the mixing frame 101. A support plate 105 is fixedly arranged at the middle position near the lower end of the inner surface of the mixing frame 101. Multiple springs 108 are fixedly arranged at the upper end of the support plate 105. Vertical plates 106 are fixedly arranged near both sides of the upper end of the support plate 105.

Horizontal sliding rods 111 are fixedly arranged near both sides of the upper end of the vibrating plate 109. L-shaped rods 113 are fixedly arranged near the lower ends of the two scrapers 112.

[0031] A first motor is fixedly connected to the front end of the stirring roller 102. The first motor is fixedly installed at the front end of the stirring frame 101. Two scrapers 112 are located above the screen 110. The two ends of the two scrapers 112 are slidably sleeved on the two horizontal slide rods 111 respectively.

The vibrating plate 109 is located at the lower end of two vibrating motors 104. The lower end of the vibrating plate 109 is fixedly connected to the upper end of multiple springs 108. The four L-shaped rods 113 are slidably sleeved in two V-shaped grooves 107 at opposite ends. The four L-shaped rods 113 are slidably sleeved in the vibrating plate 109 near the sides.

[0032] Specifically, the mixing frame 101 is the main mixing area. The bottom of the mixing frame 101 is shaped like a lower center and higher sides, allowing the raw materials to gather in the middle under gravity, facilitating the rotation and mixing of the mixing rollers 102. During use, the mixing frame 101 can be placed on the collecting device. The discharge gate 103 is electrically controlled; its retraction allows the mixed roadbed phosphogypsum to enter the collecting device. The vibration motor 104 is located at the top of the vibrating plate 109 and can drive... The vibrating plate 109 vibrates up and down. Under the action of the spring 108, the vibrating plate 109 can vibrate up and down repeatedly, which facilitates the slow falling of the raw material from the screen 110. The scraper 112 can slide horizontally along the horizontal slide bar 111 to scrape the raw material powder from the middle to both sides. One end of the L-shaped rod 113 is sleeved in the V-shaped slide groove 107. When the L-shaped rod 113 moves up and down with the vibrating plate 109, it moves horizontally along the V-shaped slide groove 107, thereby driving the scraper 112 to slide.

[0033] Reference Figure 2 , Figure 3 The feeding mechanism 2 includes a storage frame 201, an intermediate frame 207 and a connecting rod 205. The storage frame 201 is slidably provided with a feeding gate 202 near the lower end. The inner surface of the storage frame 201 is rotatably fitted with a turning roller 203.

The inner surface of the intermediate frame 207 is rotatably fitted with two rolling rollers 208.

[0034] The middle frame 207 is fixedly installed at the upper end of the mixing frame 101, the storage frame 201 is fixedly installed at the upper end of the middle frame 207, a No. 3 motor is fixedly connected to one side of the turning roller 203, the No. 3 motor is fixedly installed on the outer surface of the storage frame 201, the turning roller 203 is located below the feed gate 202, the two ends of the connecting rod 205 are respectively slidably sleeved in the front and rear ends of the storage frame 201 near the upper end, the front and rear ends of multiple partition plates 204 are respectively slidably sleeved in the front and rear ends of the connecting rod 205, the front and rear ends of multiple partition plates 204 are respectively snapped into multiple slots 206, two rolling rollers 208 are meshed and connected, a No. 2 motor is fixedly connected to one side of each of the two rolling rollers 208, and both No. 2 motors are fixedly installed on the outer surface of the middle frame 207;

[0035] Specifically, the storage frame 201 can temporarily store raw materials according to the proportion. The storage frame 201 is funnel-shaped. The feed gate 202 is electrically controlled and located inside the storage frame 201 near the lower end, controlling the entry of raw materials into the device. The turning roller 203 is located at the lower end of the feed gate 202 to prevent the raw materials from clogging at the lower end of the storage frame 201. The connecting rod 205 is divided into front and rear parts, which are U-shaped and slide on the front and rear ends of the partition plate 204 respectively. The partition plate 204 can slide horizontally along the connecting rod 205. Multiple partition plates 204 can divide the storage frame 201 into multiple areas. The movement of the partition plate 204 can change the size of each area to ensure that the size ratio of each area is the same as the proportion of the raw materials, ensuring that multiple raw materials are distributed according to the proportion. The slot 206 can fix the position of the partition plate 204. The crushing roller 208 can crush and pulverize the raw materials, especially the calcined gypsum in the raw materials, to ensure that the gypsum blocks are turned into gypsum powder, thereby ensuring the quality of the roadbed phosphogypsum after mixing.

[0036] Working principle: When the user uses the device, first place the device on the top of the collection device, move the connecting rod 205 upward to move the partition plate 204 out of the slot 206, move the position of the partition plate 204 according to the ratio of various raw materials, the partition plate 204 can slide horizontally along the connecting rod 205, after moving to the appropriate position, move the connecting rod 205 downward to the lowest position, the partition plate 204 is engaged in the corresponding slot 206, dividing the storage frame 201 into a specific size area, and then place various raw materials in the corresponding area of ​​the storage frame 201, open the feed door 202 and start the turning roller 203 at the same time, the raw materials enter the middle frame 207 from the storage frame 201 through the feed door 202. When the raw materials fall between the two crushing rollers 208, the two crushing rollers 208 turn in opposite directions, which can crush the raw materials in the middle. The crushed raw materials then enter the mixing frame 101.

[0037] When the raw material enters the mixing frame 101, it first falls onto the screen 110. The vibration motor 104 is then activated. Under the combined action of the vibration motor 104 and the spring 108, the vibrating plate 109 vibrates continuously up and down. As the vibrating plate 109 moves downwards, the L-shaped rod 113 also moves downwards. Restricted by the V-shaped groove 107, the L-shaped rod 113 moves horizontally while moving downwards, thereby driving the horizontal sliding rod 111 to move horizontally. The two horizontal sliding rods 111 move from both sides towards the middle. Conversely, when the vibrating plate 109 moves upwards... During the process, the two horizontal sliding rods 111 move from the middle to both sides in a cycle, which can move the raw material in the middle to both sides. At the same time, the vibrating plate 109 vibrates up and down, and the raw material powder falls down through the screen 110 and then falls onto the inner bottom surface of the mixing frame 101. The powder on both sides slides along the inclined bottom surface to the middle. The mixing roller 102 is started, which can continuously turn and stir the raw material powder. After it is evenly stirred, the discharge door 103 is opened, and the roadbed phosphogypsum enters the collection device from the discharge port, completing the preparation of the roadbed phosphogypsum.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
