Technical Field

[0001] This invention relates to the field of solid crushing, specifically a hammer crusher for solid waste. Background Technology

[0002] Hammer crushers are commonly used equipment in the cement industry. Current hammer crushers consist of a housing and a rotor driven by a power unit. The rotor has several crushing hammers, and a crushing chamber is formed by liners and a bottom screen around the hammers. However, in current hammer crushers, solid waste rotates in the same direction as the hammers during crushing, significantly reducing crushing efficiency. Furthermore, the fixed screen is prone to clogging by incompletely crushed waste, and the impact of the hammers on the clogged waste can easily cause significant damage to the screen.

[0003] To address the above problems, this invention provides a hammer crusher for solid waste, thereby solving the aforementioned issues. Summary of the Invention

[0042] Reference Figures 1-5 This invention provides a technical solution: a hammer crusher for solid waste, comprising:

[0043] Base 1;

[0044] Crushing mechanism 2 is fixed on the base 1;

[0045] Motor 3 is fixed on the base 1, and its output shaft is connected to the crushing mechanism 2; and

[0046] The feed inlet 4 is fixed on the crushing mechanism 2.

[0047] In a preferred embodiment, the crushing mechanism 2 includes:

[0048] The housing 21 is fixed to the base 1;

[0049] The carrier 211 is symmetrically fixed on the housing 21, and a cleaning block is slidably disposed at one end of the carrier 21 near the housing 21. A spring is disposed between the cleaning block and the carrier 211, and the cleaning block can slide and deflect within the carrier 211.

[0050] Crushing auxiliary mechanism 1 22 and crushing auxiliary mechanism 23 are axially symmetrically fixed on the housing 21 and fixedly connected to the feed port 4;

[0051] The crushing rotor 24 is rotatably mounted on the housing 21 and fixed to the output shaft of the motor 3. A pulley is also coaxially fixed on the crushing rotor 24.

[0052] The deflection mechanism 25 is symmetrically and rotatably mounted on the housing 21 and connected to the crushing rotor 24;

[0053] Deflection guides 29 are symmetrically fixed to the housing 21;

[0054] The fixing bracket 26 is rotatably mounted on the housing 21, and its two ends are fixed on the deflection guide rail 29;

[0055] Screen 27 is fixed on the fixing frame 26; and

[0056] The protective plate 28 is fixed to the housing 21.

[0057] It should be noted that the starting motor 3 drives the crushing rotor 24 to rotate at high speed in a counterclockwise direction, and then the solid waste is put into the bin through the feed port 4. First, the solid waste is crushed under the action of the crushing rotor 24 and the crushing auxiliary mechanism 22. After crushing, the solid waste is then impacted by the crushing auxiliary mechanism 22, so as to form a secondary relative collision between the solid waste and the crushing rotor 24, thereby improving the crushing efficiency of solid waste.

[0058] It should be noted that when larger solid wastes rotate to the crushing auxiliary mechanism 23 under the action of the crushing rotor 24, the crushing auxiliary mechanism 23 causes the solid wastes to collide with the crushing rotor 24 again, so that the solid wastes and the crushing rotor 24 form a relative collision again, thereby improving the crushing efficiency of solid wastes.

[0059] It should be noted that, driven by the deflection mechanism 25 and the deflection guide rail 29, the screen 27 will move in a sieving manner, which improves the sieving efficiency of solid waste and prevents larger waste from clogging the screen 27; and when the fixed frame 26 deflects, the cleaning block is kept in contact with the screen 27 by the spring, thereby cleaning the screen 27 locally and further preventing the broken solids from clogging the screen 27.

[0060] In a preferred embodiment, the first crushing auxiliary mechanism 22 and the second crushing auxiliary mechanism 23 have the same structure, both including:

[0061] A fixing block 2205 is fixed on the housing 21, and side blocks 2201 are symmetrically fixed on both sides of the fixing block 2205;

[0062] Multiple mounting slots 2202 are configured, each formed on the side stop 2201, and one end of a compression spring 2204 is fixed within each mounting slot 2202; and

[0063] The elastic plate 2203 is hinged at one end to the side stop 2201 and fixed at the other end to the other end of the compression spring 2204.

[0064] It should be explained that when the solid waste is ejected and comes into contact with the elastic plate 2203, the huge ejection force will cause the elastic plate 2203 to deflect and compress the compression spring 2204. When the ejection force is completely converted into the elastic force of the compression spring 2204, the compression spring 2204 will rebound and cause the solid waste to collide with the crushing rotor 24 at a relative collision angle, thereby improving the crushing efficiency of solid waste.

[0065] In a preferred embodiment, the angles formed by the plurality of elastic plates 2203 and the fixing block 2205 decrease gradually from bottom to top, with the lowest angle being 60° and the highest angle being 0°.

[0066] It should be noted that when the elastic plate 2203 rebounds the solid waste, the special angle setting allows the rebounded solid waste to collide with the crushing rotor 24, and at the same time, the solid waste gains relative velocity and is propelled towards the crushing rotor 24, improving the crushing effect of the collision between the solid waste and the crushing rotor 24.

[0067] In a preferred embodiment, the angle formed by the multiple elastic plates 2203 and the fixed block 2205 in the second crushing auxiliary mechanism 23 gradually increases from bottom to top.

[0068] It should be noted that when the solid waste rotates with the crushing rotor 24 to the crushing auxiliary mechanism 23, the crushing auxiliary mechanism 23, which is fixed at a special angle on the housing 21, can increase the relative collision intensity between the solid waste and the crushing rotor 24 after contact with the solid waste, thereby further improving the crushing effect of the solid waste.

[0069] In a preferred embodiment, the deflection guide 29 includes:

[0070] A U-shaped frame 2901 is fixed to the housing 21, and an arc-shaped shaft 2902 is fixed inside the U-shaped frame 2901. Two compression springs 2903 are sleeved on the arc-shaped shaft 2902.

[0071] The sliding cone 2904 is slidably disposed on the arc-shaped shaft 2902 and located between the two compression springs 2903.

[0072] It should be noted that during the rotation of the deflection mechanism 25, the sliding cone 2904 slides up and down on the arc-shaped shaft 2902, which enables the fixed frame 26 and the screen 27 to achieve a sieving effect, improves the sieving efficiency of the crushed solid waste, and prevents larger solid waste from clogging the screen 27.

[0073] In a preferred embodiment, the deflection mechanism 25 includes:

[0074] Cam 2501 is rotatably mounted on housing 21. Pulley 2502 is fixed on cam 2501. One end of drive shaft 2505 is fixed on pulley 2502. Pulley 2501 and pulley 2502 are driven by belt.

[0075] Top rod 2503, fixed on the fixing bracket 26; and

[0076] Cam 2506 is rotatably mounted on the housing 21 and fixed to the other end of the transmission shaft 2505. The relative installation angle between Cam 2506 and Cam 1 is 180°.

[0077] It should be noted that when cam 1 2501 lifts the push rod 2503, the sliding cone 2904 on the side of the push rod 2503 that is lifted slides upward with the arc-shaped shaft 2902. At the same time, because the installation angle between cam 22506 and cam 1 2501 is 180°, that is, cam 22506 is not in contact with the push rod 2503, the sliding cone 2904 on this side will slide downward with the arc-shaped shaft 2902, so that the fixed frame 26 and the screen 27 will tilt and deflect. In this working state, cam 1 2501 and cam 22506 periodically lift the push rod 2503, so that the screen 27 will periodically deflect, thus forming a tumbling effect of the screen 27, improving the screening efficiency of solid waste and preventing larger solid waste from clogging the screen 27 during the tumbling process.

[0078] In practice, the motor 3 is started to make the crushing mechanism 2 start working. Solid waste enters the crushing mechanism 2 through the feed port 4. In the crushing mechanism 2, the crushing auxiliary mechanism 1 22 and the crushing auxiliary mechanism 23 make the solid waste collide with the crushing rotor 24, thereby improving the crushing effect of solid waste.

[0079] It should be noted that, under the action of the deflection mechanism 25 and the deflection guide rail 29, the screen 27 is made to screen the crushed solid waste in the form of sieving, while preventing the solid waste from clogging the screen 27.

[0080] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
