Description

Technical Field

[0001] This utility model relates to the field of calcium chloride production technology, specifically to a pulverizer that facilitates automatic feeding. Background Technology

[0002] Calcium chloride is an important inorganic chemical product. Its production process usually uses limestone or brine resources as raw materials. It generates calcium chloride solution through neutralization reaction with hydrochloric acid. After purification to remove impurities, the solution is evaporated and concentrated, cooled and crystallized or spray-dried to finally obtain products in different forms such as anhydrous calcium chloride and dihydrate calcium chloride. In the production process of calcium chloride, it is necessary to use a pulverizer to crush the raw materials and obtain the target particle size product by classification through a vibrating screen.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Existing crushers mainly rely on manual feeding, and their feeding process is prone to accumulation and blockage. In addition, the feeding amount lacks precise adjustment, resulting in a low degree of matching with the crushing efficiency. Furthermore, they are not adaptable to different materials, which can limit the efficiency of raw material processing. Utility Model Content

[0009] More preferably, the shock absorption mechanism includes a support frame plate, the bottom of which is located at the top of a support frame sleeved at one end of the conveying mechanism, and four spring brackets are provided at the four corners of the top of the support frame plate, with the tops of the four spring brackets screwed to the four corners of the bottom of the tray.

[0010] More preferably, the conveying mechanism includes a feed pipe, the bottom end of which is vertically inserted through a conveying cylinder, and a spiral conveying rod rotatably connected to the inner walls of the left and right sides of the conveying cylinder. One end of the spiral conveying rod is connected to a stepper motor. A discharge pipe is provided on the bottom side of the conveying cylinder away from the feed pipe, the bottom end of which is vertically inserted through the top opening of the second feed hopper, and the top end of the feed pipe is attached to the bottom side of the tray.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The spiral guide pattern in the first feed hopper guides the material down a spiral, dispersing it evenly and preventing blockage. The pneumatic butterfly valve, linked to the weight sensor and the first vibration motor, adjusts the feeding amount in real time to ensure stable feeding. The tilting tray of the feeding mechanism, in conjunction with the first vibration motor, makes the material slide at a uniform speed. The weight feedback precisely controls the feeding amount to adapt to the working conditions. At the same time, the shock absorption mechanism absorbs vibration energy, which can reduce equipment resonance loss and improve operational stability. Meanwhile, the conveying mechanism can stably transport materials and precisely adjust the speed, which can be matched with the crushing efficiency to avoid overload or idling, ensuring continuous and coordinated process.

[0022] In this embodiment, as Figure 1 and Figure 3 As shown, the inner wall of the first feed hopper 1 is provided with spiral guide patterns, and a pneumatic butterfly valve 101 is installed on the bottom outer wall of the first feed hopper 1.

[0023] In this embodiment, as Figure 1 and Figure 3 As shown, the feeding mechanism 2 includes a tray 201. A first vibration motor 202 is screwed to the front and rear sides of the bottom of the tray 201. A weight sensor 203 is provided in the middle of the bottom of the tray 201. A shock-absorbing mechanism 3 is provided at the four corners of the bottom of the tray 201. The bottom wall of the tray 201 is inclined. The bottom of the tray 201 is the lowest point on the side of the bottom of the tray 201 closest to the conveying mechanism 4.

[0024] In this embodiment, as Figure 3 As shown, the shock absorption mechanism 3 includes a support frame plate 301. The bottom of the support frame plate 301 is located at the top of the support frame sleeved at one end of the conveying mechanism 4. Four spring brackets 302 are provided at the four corners of the top of the support frame plate 301. The tops of the four spring brackets 302 are screwed to the four corners of the bottom of the tray 201.

[0025] In this embodiment, as Figure 2 As shown, the conveying mechanism 4 includes a feed pipe 401, the bottom end of which is vertically connected to a conveying cylinder 402. The inner walls of the left and right sides of the conveying cylinder 402 are rotatably connected to a spiral conveying rod 403. One end of the spiral conveying rod 403 is connected to a stepper motor 404. The bottom of the conveying cylinder 402 is provided with a discharge pipe 405 on the side away from the feed pipe 401. The bottom end of the discharge pipe 405 is vertically connected to the top opening of the second feed hopper 5. The top end of the feed pipe 401 is attached to the bottom side of the tray 201.

[0026] In this embodiment, as Figure 4 As shown, the crushing mechanism 7 includes a servo motor 701. The output end of the servo motor 701 is connected to a main rotating rod 702. A drive gear 703 is sleeved on the outer wall of the end of the main rotating rod 702. A driven gear 704 meshes on one side of the drive gear 703. A driven rod 705 is sleeved on the inner wall of the driven gear 704. Several crushing blades 706 are sleeved on the outer walls of the main rotating rod 702 and the driven rod 705. The two ends of the main rotating rod 702 and the driven rod 705 are rotatably connected to the inner walls of the left and right sides of the crushing box 6, respectively.

[0027] In this embodiment, as Figure 4 As shown, the screening mechanism 8 includes a screen plate 801, and a second vibration motor 802 is screwed to the inner walls of the left and right sides of the screen plate 801. The screen plate 801 is slidably connected to the inner wall of the crushing box 6.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the operation process of this pulverizer, which facilitates automatic feeding, is as follows:

[0029] First, the operator can pour the block or granular calcium chloride raw material into the first feed hopper 1, allowing the material to slide downwards along the spiral guide pattern under gravity. At this time, the pneumatic butterfly valve 101 is opened, allowing the calcium chloride raw material to continue falling downwards onto the tray 201 of the feeding mechanism 2. Simultaneously, the operator can start the first vibration motor 202 to generate high-frequency vibration, causing the entire tray 201 to vibrate together, thereby causing the material on the tray 201 to slide evenly towards the lower end. During this process, the weight sensor 203 at the bottom of the tray 201 will monitor the weight of the material in real time and feed the data back to the control system, thereby adjusting the vibration frequency of the first vibration motor 202 to achieve precise control of the feed amount. At the same time, the spring bracket 302 will absorb the energy of the tray 201 vibration during the entire feeding process, ensuring stable operation of the equipment.

[0030] When the material slides to the lowest point of the tray 201, it falls into the feed pipe 401 attached to the bottom side of the tray 201, and then enters the conveyor cylinder 402. At the same time, the operator can start the stepper motor 404, which drives the inserted spiral conveyor rod 403 to start rotating, thereby pushing the material along the spiral trajectory towards the end of the conveyor cylinder 402 until the material is conveyed to the discharge pipe 405 and discharged from it, and then falls vertically into the second feed hopper 5 directly below. During this process, the material is guided by the second feed hopper 5. Then it enters the crushing chamber 6. At the same time, the servo motor 701 is started to drive the main rotating rod 702 and the drive gear 703 sleeved on the outer wall of its end to rotate together. During this period, the driven gear 704 meshing on one side of the drive gear 703 and the driven rotating rod 705 sleeved on the inner wall of the driven gear 704 will be rotated synchronously, so that the crushing blades 706 sleeved on the outer wall of the main rotating rod 702 and the driven rotating rod 705 will rotate in opposite directions, and shear and impact crush the calcium chloride material falling into the crushing chamber 6.

[0031] The crushed material falls onto the screen plate 801 located directly below the crushing mechanism 7. At this time, the operator can start the second vibration motor 802 screwed on both sides to drive the screen plate 801 to vibrate at high frequency, so that the crushed material is vibrated and screened on the screen plate 801. During this process, fine powder that meets the preset particle size falls through the screen holes into the discharge channel at the bottom of the crushing box 6 and is discharged from there, entering the subsequent collection process.
