DETAILED DESCRIPTION

[0024] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0025] refer to Figures 1 to 6

[0026] A raw material pulverizing device for taurine production includes a pulverizing chamber 10, within which an annular screen 20 is disposed for controlling the fineness of the pulverized particles. A cutterhead 30 is located inside the annular screen, equipped with a tool assembly. The cutterhead is driven by a drive mechanism to achieve high-speed rotation of the tool assembly. A cover plate 40 is mounted at the front end of the pulverizing chamber, a dust removal mechanism is mounted at the top of the pulverizing chamber, and a discharge port 11 is located at the bottom of the pulverizing chamber. A fixed disk 50, which cooperates with the tool assembly, is mounted at the rear end of the cover plate. The cover plate has a feed port 41 extending through the middle of the fixed cutterhead. Raw materials for sulfuric acid production are fed into the pulverizing chamber through the feed port. The raw materials are pulverized by the rotation of the cutterhead and the tool assembly in conjunction with the fixed disk. Particles smaller than the mesh size of the annular screen fall down and are discharged through the discharge port. A container for receiving the raw materials may be installed below the discharge port. Dust generated during pulverization is extracted by the dust removal mechanism, reducing dust pollution.

[0027] In this embodiment, there is a gap 12 between the circumferential surface of the annular screen and the circumferential inner wall of the crushing chamber to allow the crushed raw materials to fall. The discharge port is located on the lower side of the annular screen and has a certain distance from the annular screen, allowing the raw materials that meet the particle fineness to fall into the discharge port by gravity.

[0028] In this embodiment, the dust removal mechanism includes a dust suction port 13 connected to the upper end of the pulverizing chamber. This port is connected to an exhaust fan 14, which is a small exhaust fan, such as the exhaust fan of a handheld vacuum cleaner. The exhaust fan's output is connected to a dust collection bag 16 via a pipe 15. A filter can be provided on the dust suction port to prevent the raw material particles from being sucked away. The exhaust fan draws the dust into the dust collection bag for collection and subsequent processing.

[0029] In this embodiment, the tool assembly includes a plurality of protruding rotating steel teeth 31 arranged at intervals along the circumferential direction on the front end face of the cutter disc, and the front end face of the cutter disc is provided with three circles of rotating steel teeth from the outside to the inside; the rear end face of the fixed knife is provided with two circles of fixed steel teeth 51 arranged at intervals along the circumferential direction, and the fixed steel teeth and the rotating steel teeth are radially staggered along the radial direction of the cutter disc, so that the raw materials can be better crushed.

[0030] In this embodiment, a radial paddle 32 is fixed to the middle of the blade disc, located inside the inner ring of rotating steel teeth. The radial paddle can be V-shaped. As the radial paddle rotates, the incoming material is moved between the rotating and fixed steel teeth for crushing, preventing the material from concentrating in the middle of the blade.

[0031] In this embodiment, the front end of the cutter disc is provided with a circumferentially corrugated cutter disc ridge 33, with the ends of the fixed steel teeth in close proximity to the cutter disc ridge. The rear end of the fixed disc is provided with a circumferentially corrugated fixed disc ridge 52, with the ends of the rotating steel teeth in close proximity to the fixed disc ridge. Thus, the coordination between the fixed steel teeth and the cutter disc ridge, and the rotating steel teeth and the fixed disc ridge, allows for grinding of the raw material, improving its particle fineness.

[0032] In this embodiment, in order to facilitate the input of raw materials, an inclined feed hopper 60 is installed on the feed port through a fixed frame. The width of the feed hopper gradually decreases from the upper end to the feed port. A baffle 61 is provided on the upper side of the section of the feed hopper close to the feed port, and a guide plate 64 is provided on the lower side of the baffle of the feed hopper so that the raw materials can be introduced into the crushing chamber more evenly.

[0033] In this embodiment, a feed gate 62 is vertically provided at the end where the feed hopper is connected to the feed port, and a hand-tightening bolt 63 for fixing the feed gate is screwed on the upper part of the fixing frame to control the opening and closing of the feed port.

[0034] In this embodiment, to facilitate opening and closing of the cover, one side of the cover is hingedly connected to the pulverizing chamber via a hinge 42. A locking plate 43 is fixed to the other side of the cover, along with a handle. The locking plate is provided with a transverse groove. A longitudinally arranged screw 17 is hingedly connected to the outer wall of the pulverizing chamber on the other side, and a rotating wheel 18 is screwed onto the screw. Once the screw engages the transverse groove, the rotating wheel rotates to seal the cover and the pulverizing chamber.

[0035] In this embodiment, a frame 1 is further included, and the crushing chamber is fixed on the table of the frame.

[0036] In this embodiment, the drive mechanism includes a rotating shaft 70 rotatably connected to the pulverizing chamber. One end of the rotating shaft is fixedly connected to the cutter disc, and the other end is connected to a motor 71 mounted on the frame surface. Alternatively, the other end of the rotating shaft is fixed to a pulley and is connected to the motor mounted on the frame surface via a transmission belt. This drives the cutter disc and the tool assembly to rotate.

[0037] In this embodiment, the annular screen is detachably installed in the crushing chamber.

[0038] During use, the raw materials are evenly introduced into the crushing chamber through the feed hopper and the feed port, and the feed port is closed; the motor is started to drive the cutter disc to rotate with the cutter assembly and cooperate with the fixed disc to crush the raw materials; the crushed raw materials are discharged from the discharge port through the annular screen; the dust removal system works at the same time to absorb and process the generated dust.

[0039] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).

[0040] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.

[0041] Any component provided by the present invention can be assembled from multiple separate components, or can be a separate component manufactured by an integral forming process.

[0042] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
