Description

Technical Field

[0001] This utility model relates to the field of sodium metal pelletizing technology, and in particular to a fully automatic explosion-proof sodium block pelletizing machine. Background Technology

[0002] Sodium is a chemically highly reactive and soft alkali metal element that readily reacts violently with water and oxygen. Its reaction with water produces sodium hydroxide and hydrogen gas, releasing a large amount of heat and potentially causing combustion or even explosion. In air, sodium rapidly oxidizes, producing sodium oxide and other corrosive substances. Sodium has wide industrial applications, including the manufacture of various chemical products, as a reducing agent in certain metal smelting processes, and as a coolant in nuclear reactors. However, sodium is also harmful to humans. When sodium comes into contact with moisture on the skin, the resulting sodium hydroxide is highly corrosive and can cause burns, leading to redness, swelling, pain, blisters, and even ulcers.

[0003] When granulating metallic sodium, fully automated specialized granulation equipment must be used, and the process must be carried out by qualified personnel. Existing methods for granulating sodium blocks by users are varied and often involve homemade tooling, fixtures, and simple equipment, which are generally not explosion-proof. In particular, manual methods, such as first cutting the sodium into flakes with a guillotine or kitchen knife and then cutting it into granules with scissors, result in inconsistent granule sizes, insufficient fragmentation, and the easy retention of metallic sodium on the cutting blade. These methods not only affect processing efficiency but also pose potential safety hazards due to the inherent high risk of metallic sodium during granulation. Utility Model Content

[0004] The purpose of this section is to provide a fully automatic explosion-proof sodium block pelletizer that can safely and efficiently cut metallic sodium into fine particles.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fully automatic explosion-proof sodium block pelletizing machine, including a slicing mechanism and a pelletizing mechanism. Both the slicing mechanism and the pelletizing mechanism include a worktable. A conveyor belt is provided on the top of the worktable. A pressure roller assembly and a lower cutting assembly are provided above the worktable. The pressure roller assembly is used to flatten the raw material and convey it to the conveyor belt. The lower cutting assembly includes a cutter. The cutter located on the slicing mechanism is connected to a stripping plate. The cutter located on the pelletizing mechanism is connected to several blades perpendicular to the cutter. The blades are flush with the ends of the cutter. A fixing plate is provided on one side of the blade. Several scrapers are connected to the fixing plate. The scrapers are stripping plates made of polytetrafluoroethylene material with a shape opposite to that of the pelletizing blade. During operation, the stripping blocks and the pelletizing blades are interleaved.

[0006] As a preferred embodiment of the fully automatic explosion-proof sodium block pelletizer of this utility model, the cutter is detachably connected to a mounting plate, and piston rods are fixedly connected to both ends of the mounting plate. The worktable is provided with a sliding groove that cooperates with the piston rod, and the piston rod can move up and down within the sliding groove.

[0007] As a preferred embodiment of the fully automatic explosion-proof sodium block pelletizer of this utility model, the pressure roller assembly includes a conveyor belt and a circular roller, the circular roller is located above the conveyor belt, one end of the circular roller is connected to an adjusting rod, and the adjusting rod is threadedly connected to the worktable.

[0008] As a preferred embodiment of the fully automatic explosion-proof sodium block pelletizer of this utility model, side plates are provided on both sides of the conveyor belt, a support base is connected to the end of the side plate away from the lower cutting component, a pad is connected to the bottom of the support base, and the pad is fixedly connected to the worktable.

[0009] As a preferred embodiment of the fully automatic explosion-proof sodium block pelletizer of this utility model, an L-shaped block is provided at one end of the side plate near the lower cutting component, and a screw is threadedly connected to the L-shaped block.

[0010] As a preferred embodiment of the fully automatic explosion-proof sodium block pelletizer of this utility model, the side plate is provided with a groove, and the circular roller is located in the groove.

[0011] As a preferred embodiment of the fully automatic explosion-proof sodium block pelletizer of this utility model, wherein: the end of the pressure roller assembly is provided with an arc-shaped plate.

[0012] As a preferred embodiment of the fully automatic explosion-proof sodium block pelletizer described in this utility model, a guide plate is inclinedly arranged on one side of the workbench.

[0013] The beneficial effects of this utility model are:

[0014] 1. The slicing mechanism uses a pressure roller assembly to fix a block of metallic sodium with a diameter of 70-90mm and a length of 250-300mm. The sodium is then fed into the cutting edge by a conveyor belt for slicing. The slicing thickness and speed are controlled by a special knob on the explosion-proof electrical control box. Generally, the sodium slice thickness is 3-6mm and the slicing speed is 5-10 rpm. The cutting blade presses down and then lifts up to remove the sodium slices. The sodium slices that fall off the conveyor belt of the slicing machine are then fed to the pelletizer. This process is continuous. After each cutting action, a scraper scrapes the sodium slices off the blade to prevent them from sticking to the blade and ensure they fall safely onto the conveyor belt.

[0015] 2. The pelletizing mechanism collects sodium flakes from the slicer via a conveyor belt and places them under the pelletizing blade. The pelletizing blade has multiple blades perpendicular to the cutting edge, forming multiple mutually perpendicular cutting edges to cut the metallic sodium on the conveyor belt. This process cuts the metallic sodium into square or rectangular particles with a width of 5-10 mm and a length of 5-10 mm. The particle width is determined by the cutting blade, and the particle length is controlled by a speed switch on the explosion-proof electrical control box. A scraper block is installed between every two adjacent blades. This scraper block is a custom-made stripping plate made of polytetrafluoroethylene (PTFE) with a shape opposite to that of the pelletizing blade. During operation, the stripping block and the pelletizing blade are interleaved. After each cutting action, the cutting blade passes through the scraper block to remove residual metallic sodium, preventing resource waste and safety hazards.

[0016] 3. First, a stripping plate is connected to the cutter on the slicing mechanism. Then, multiple blades perpendicular to the cutter are set at the end of the cutter on the pelletizing mechanism, forming multiple mutually perpendicular cutting edges. During operation, the metallic sodium on the conveyor belt is first sliced ​​and conveyed to the pelletizer. The metallic sodium is then cut into particles of the specified size and collected by the conveyor belt. After each cutting action, the cut sodium flakes or particles are scraped off by the scraper or stripping plate and fall onto the conveyor belt, thus scraping away residual metallic sodium and preventing metallic sodium from sticking to the blade surface. This improves pelletizing accuracy and speed and eliminates the safety hazards caused by manual sodium cutting. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more easily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. The term "embodiment" as used herein refers to a particular feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0028] Example

[0029] Reference Figures 1-7 This embodiment provides a fully automatic explosion-proof sodium block pelletizer, specifically including a slicing mechanism and a pelletizing mechanism. Both the slicing mechanism and the pelletizing mechanism include a worktable 1, with a conveyor belt 2 mounted on top of the worktable 1. A pressure roller assembly and a cutting assembly are mounted above the worktable 1. The pressure roller assembly is used to flatten the raw material and convey it to the conveyor belt 2. The cutting assembly includes a cutter 401. The cutter 401 on the slicing mechanism is connected to a stripping plate 405. The cutter 401 on the pelletizing mechanism is connected to several blades 402 perpendicular to the cutter 401. The blades 402 are flush with the ends of the cutter 401. A fixing plate 5 is provided on one side of the blade 402. Several scrapers 6 are connected to the fixing plate 5, and the scrapers 6 are interlaced with the blades 402. The cutter 401 is detachably connected to a mounting plate 403. Piston rods 404 are fixedly connected to both ends of the mounting plate 403. The worktable 1 has a sliding groove that cooperates with the piston rods 404, allowing the piston rods 404 to move up and down within the sliding groove.

[0030] The height of the upper conveyor belt 2 of the slicing mechanism is higher than that of the upper conveyor belt 2 of the pelletizing mechanism. After being sliced ​​by the slicing mechanism, the raw material falls into the guide plate 7 and then onto the pelletizing mechanism for the subsequent pelletizing process.

[0031] The fixed plate 5 and scraper 6 serve as the pelletizing and unloading mechanism. The scraper 6 is made of non-stick polytetrafluoroethylene material, and a certain gap is formed between two adjacent scraper 6. It works in conjunction with the cutter 401 to lift the blade 402 while unloading the material. The conveyor belt 2 moves forward to transport the cut pellets. The unloading plate 405 on the slicing mechanism also uses a non-stick scraper, which can prevent sodium flakes or sodium pellets from sticking to the cutter 401 during slicing or pelletizing.

[0032] The pressure roller assembly is used to compress irregular or irregularly sized sodium blocks into sheet-like metallic sodium of a certain thickness. The distance between adjacent cutters 401 is the same, as is the distance between adjacent scrapers 6. The piston rod 404 is driven by an internal drive mechanism, causing it to move up and down at a uniform speed.

[0033] The pressure roller assembly includes a conveyor belt 301 and a circular roller 302. The circular roller 302 is located above the conveyor belt 301, and an adjusting rod 303 is connected to one end of the circular roller 302. The adjusting rod 303 is threadedly connected to the worktable 1. Side plates 304 are provided on both sides of the conveyor belt 301. A support base 305 is connected to the end of the side plate 304 away from the cutting assembly. A pad 306 is connected to the bottom of the support base 305 and is fixedly connected to the worktable 1. An L-shaped block 307 is provided at the end of the side plate 304 near the cutting assembly. A screw 308 is threadedly connected to the L-shaped block 307. The side plate 304 has a groove, and the circular roller 302 is located in the groove. An arc-shaped plate 309 is provided at the end of the pressure roller assembly. A guide plate 7 is inclinedly provided on one side of the worktable 1.

[0034] A brush roller 8 is installed below the conveyor belt 2 to clean the sodium residue on the conveyor belt 2 and prevent it from causing harm.

[0035] The adjusting rod 303 is used to adjust the height of the circular roller 302, thereby adjusting the distance between the circular roller 302 and the conveyor belt 301. The screw 308 is used to adjust the height of the end of the conveyor belt 301. The arc-shaped plate 309 is connected to the side plate 304 on both sides, serving as a protective barrier to prevent metallic sodium from falling or splashing under the action of the conveyor belt 301. One end of the conveyor belt 301 is raised through the pad 306, causing the conveyor belt 301 to tilt downwards to transport metallic sodium. A drive mechanism for driving the conveyor belt 301 is connected to one side of the conveyor belt 301.

[0036] During processing, the sodium block raw material has a diameter of 70-90mm and a length of 250-300mm. The first slice is 3-6mm thick, and the second granulation is 5-10mm wide. After the stepper motor feeds the material for 5-10mm, the cutter 401 presses down simultaneously, followed by lifting the cutter and feeding, continuing the process continuously. The slicing mechanism and the granulation mechanism can be designed with separate speeds and feeding distances, and used in conjunction with each other.

[0037] During use, operators must ensure that there is no sodium residue on the workbench 1 and the cutter 401, perform relevant inspections, and keep the equipment clean and tidy. Adjust the distance between the roller 302 and the conveyor belt 301, as well as the cutting speed of the cutter 401, according to the size and shape of the raw material. Use a plastic rod to push the sodium block into the appropriate position, completing the automatic conveying, cutting, and discharging processes.

[0038] Importantly, although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible without substantially departing from the subject matter described in this application, such as changes in the size, structure, shape, and proportion of various elements, as well as variations in temperature, pressure, installation arrangement, material use, color, orientation, etc.; for example, an element shown as integrally formed may be composed of multiple parts or elements, and the position of the elements may be inverted or otherwise altered; therefore, all such modifications should be included within the scope of this invention, and other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments without departing from the scope of this invention.
