[0024] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0025] Figure 1 The diagram shows a front view of the mechanical crusher according to an embodiment of the present invention. Figure 2 A side view of the mechanical pulverizer according to an embodiment of the present invention is shown. (Combined with...) Figure 1 and Figure 2 As shown, a mechanical crusher includes a hinge 6, a frame 1, a crushing component 3, a filtering component 4, a receiving tank 5, and a feeding device 2 disposed on the upper end of the frame 1.

[0026] Hinge 6 is mounted on frame 1 and connects to crushing assembly 3. The inlet of crushing assembly 3 is connected to feeding device 2 and air source respectively. The outlet of crushing assembly 3 is tangentially connected to the outer periphery of inlet and outlet of filter assembly 4 at a preset angle. Collection tank 5 is connected to the lower end of inlet and outlet of filter assembly 4.

[0027] When disassembling the crushing component 3, the hinge 6 connects to the crushing component 3, which facilitates operation inside the crushing component 3, avoids frequent disassembly and assembly of the inlet of the crushing component 3, and improves the sealing performance of the crushing component 3.

[0028] Material is quantitatively fed in by the feeding device 2. Gas carries the material into the crushing component 3, where it is ground into powder. Gas then drives the powder out of the crushing component 3 and into the filtering component 4 to filter the powder. The gas then exits the filtering component 4, and the powder accumulates and falls into the collection tank 5 for collection, resulting in high material grinding efficiency and efficient powder collection.

[0029] The mechanical crusher includes a feeding device 2, a crushing component 3, a filtering component 4, and a receiving tank 5. The mechanical crusher has a simple structure and can complete the crushing of materials. The mechanical crusher eliminates the blower, reduces weight, and is easy to move.

[0030] The frame 1 houses the electrical cabinet 11 and the control panel 12. The control panel 12 is connected to the electrical cabinet 11, and the output of the electrical cabinet 11 is connected to the feeding device 2 and the crushing assembly 3. The control panel 12 outputs signals to the electrical cabinet 11, which supplies power and transmits signals to control the feeding device 2 and the crushing assembly 3, thus operating the mechanical crusher.

[0031] The feeding device 2 includes a first power unit 24, an outer cylinder 21, a screw 22 rotatably disposed inside the outer cylinder 21, and an inlet mask 23 communicating with the outer cylinder 21. Material enters the outer cylinder 21 through the inlet mask 23. The first power unit 24 drives the screw 22 to rotate, and the screw 22 pushes the material to move and discharge it from the outer cylinder 21. By controlling the power of the first power unit 24, the material discharge speed is controlled, achieving quantitative material conveying.

[0032] The inlet of the crushing component 3 is connected to the lower end of the inlet pipe 31. The upper end of the inlet pipe 31 is connected to the feeding device 2, and the middle of the pipe 31 is connected to the air source. The material falls into the inlet pipe 31 and mixes with the gas. The diameter of the inlet pipe 31 gradually decreases, the flow rate of the gas and material increases, and the material quickly impacts the crushing component 3, which facilitates the crushing component 3 to grind the material.

[0033] The mechanical crusher also includes locking mechanisms 7 located at the front and rear ends of the outer cylinder 21. One set of locking mechanisms 7 fastens the inlet pipe 31 and the outer cylinder 21, and the other set of locking mechanisms 7 fastens the outer cylinder 21 and the drive end of the first power device 24 to ensure the sealing of the connection between the front and rear ends of the outer cylinder 21.

[0034] The locking mechanism 7 includes clamps 71 hinged at one end, a locking rod 72 hinged to the other end of one set of clamps 71, and a locking handle 73 that presses against the other end of another set of clamps 71. The locking handle 73 is threaded onto the locking rod 72. Flanges are formed at the connection points of the front and rear ends of the outer cylinder 21, the inlet pipe 31, and the drive end of the first power unit 24. The clamps 71 are used to fasten the flanges.

[0035] When closing clamp 71, swing the locking rod 72 upwards and then tighten the locking handle 73 downwards to push the other end of clamp 71 closer together. The two sets of clamps 71 quickly seal and lock, ensuring the sealing of material conveying from feeding to grinding.

[0036] When opening clamp 71, rotate lock handle 73 upwards to loosen it. After lock handle 73 disengages from clamp 71, swing lock rod 72 downwards to disengage clamp 71 from flange, allowing for quick disassembly.

[0037] The grinding assembly 3 includes a second power unit 33 that drives the grinding disc 32 to rotate, a housing 34 mounted on the frame 1, and the grinding disc 32 rotatably mounted inside the housing 34. The housing 34 consists of a shell and a cover forming a sealed space, within which the grinding disc 32 rotates.

[0038] The hinge 6 includes a chain seat 61 and a chain 62. The chain seat 61 is respectively mounted on the frame 1 and the outer shell 34. The chain 62 is formed by several chain blocks hinged together in sequence, and the two ends of the chain 62 are hinged to the chain seat 61, connecting the frame 1 and the shell cover. The shell cover is removed, and the shell cover is connected to the chain 62, allowing the operator to directly operate the shell. After completion, the shell cover is pushed to close the shell, facilitating operation by one operator.

[0039] When removing the cover, it is not necessary to separate the inlet pipe 31 from the cover. Simply remove the cover and a locking mechanism 7 to ensure a seal between the inlet pipe 31 and the outer casing 34.

[0040] The outlet of the crushing component 3 forms a discharge pipe 35. The discharge pipe 35 bends downward and then bends upward to form a curved section 36. The curved section 36 slows down the flow rate of gas and powder, preventing the discharge pipe 35 from passing directly through the inlet and outlet of the filter component 4.

[0041] The filter assembly 4 includes several filter cartridges 41. The lower ends of the filter cartridges 41 are connected to the inlet and outlet of the filter assembly 4.

[0042] The discharge pipe 35 is tangentially connected to the outer periphery of the inlet and outlet of the filter assembly 4 at a preset angle. Gas and powder form an annular flow path at the inlet and outlet of the filter assembly 4. Gas and powder flow upward uniformly and act on the filter cartridge 41, avoiding overloading of a single filter cartridge 41 for filtration.

[0043] A butterfly valve 51 is installed between the inlet and outlet of the receiving tank 5 and the filter assembly 4. After the mechanical crusher stops working, the butterfly valve 51 opens the receiving tank 5, and the powder filtered in the filter cartridge 41 falls into the receiving tank 5 for collection. After completion, the butterfly valve 51 closes the receiving tank 5, and the mechanical crusher continues to work. Replacing the receiving tank 5 improves working efficiency.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
