Description

Technical Field

[0001] This utility model relates to the field of crushers, and more specifically, to a particle crusher. Background Technology

[0002] Calcium aluminate is an important inorganic chemical material widely used in water treatment, refractory materials, cement additives, and environmental protection. Due to its special chemical properties, calcium aluminate is a porous material with a large specific surface area. When exposed to a humid environment, it will quickly absorb moisture, causing liquid bridges to form between particles, which in turn promotes the agglomeration of fine particles into lumps. Calcium aluminate easily absorbs moisture during production and storage, forming lumpy materials with high moisture content. Calcium aluminate is a key raw material for preparing high-efficiency water purification agents such as polyaluminum chloride (PAC). Its reaction rate is closely related to its specific surface area. The finer the particles, the faster the dissolution and reaction rate, thereby improving the polymerization degree and flocculation effect of PAC.

[0003] For example, patent (CN222197080U) discloses a raw material crusher for calcium aluminate powder. The drive component of the raw material crusher for calcium aluminate powder will cause the fan blades to rotate. When the fan blades rotate, the air inside the square groove will flow, which will carry the scattered dust. When the dust follows the air flow to the fan blades, the filter plate will filter and adsorb the flowing dust, thereby achieving the purpose of filtering and adsorbing the dust, effectively preventing the dust from spreading and affecting the surrounding environment, and improving the practicality of the raw material crusher for calcium aluminate powder.

[0004] When using the above technology, the following technical problems were found in the existing technology: the equipment is mainly for dry or low moisture content calcium aluminate powder. For high moisture content lumpy calcium aluminate, it may still cause the filter plate and crushing chamber to be blocked due to adhesion. Direct crushing will lead to a decrease in efficiency. Therefore, we designed a particle crusher to provide another technical solution to the above technical problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a granulator that preheats and dries calcium aluminate through an S-shaped heating copper tube before pulverization, thereby reducing the moisture content of the material and reducing the energy consumption of subsequent pulverization. This makes the pre-treated material easier to pulverize, thus improving the reaction speed and efficiency of subsequent calcium aluminate processing.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A pellet crusher includes a crushing box, a feeding port at the top of the crushing box, a rectangular screening frame inside the crushing box, a stainless steel screen fixed inside the rectangular screening frame, an S-shaped heating copper tube at the bottom of the stainless steel screen, rotatable longitudinal baffles at both ends inside the rectangular screening frame, and a rotating mechanism for rotating the longitudinal baffles on the outside of the rectangular screening frame.

[0010] The outside of the crushing box is equipped with a moving mechanism for moving the rectangular screening rack.

[0011] Furthermore, the rotating mechanism includes a transverse dual-output shaft motor, which is fixed to the outside of the rectangular screening rack. The output end of the transverse dual-output shaft motor is rotatably connected to a first transverse transmission column via a pin. The end of the first transverse transmission column away from the transverse dual-output shaft motor is rotatably connected to a transverse rotating column via a pin. A longitudinal rotating rod is fixed inside the top of the transverse rotating column. The longitudinal rotating rod passes through the interior of the longitudinal baffle and is fixedly connected to the longitudinal baffle.

[0012] Furthermore, the longitudinal rotating rod passes through the interior of the rectangular screening frame and is rotatably connected to the rectangular screening frame via a bearing.

[0013] Furthermore, a second drive motor is bolted to the bottom of the outer side of the crushing box, and a longitudinal stirring rod is fixed to the output end of the second drive motor.

[0014] Furthermore, the rotating mechanism includes an L-shaped mounting plate located outside the crushing chamber and fixedly connected to it. A first drive motor is bolted to one end of the L-shaped mounting plate, and a second transverse transmission column is fixed to the output end of the first drive motor. One end of the second transverse transmission column is rotatably connected to an L-shaped transverse sliding plate via a pin.

[0015] Furthermore, a rectangular slider is fixed to the side of the L-shaped horizontal sliding plate near the crushing box, and a rectangular groove is provided inside the crushing box.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] This solution employs a series of design features, including preheating and drying calcium aluminate via an S-shaped heating copper tube before pulverization to reduce the material's moisture content and decrease subsequent pulverization energy consumption. The rectangular screening rack's lateral reciprocating motion, combined with the longitudinal baffle angle adjustment, causes the material to tumble on the stainless steel screen, preventing wet and sticky materials from clumping together. This makes the pre-treated material easier to pulverize, thereby improving the reaction speed and efficiency of subsequent calcium aluminate processing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Please see Figure 1-7 A pellet crusher includes a crushing box 1, a feeding port 2 at the top of the crushing box 1, a rectangular screening frame 5 inside the crushing box 1, a stainless steel screen 6 fixed inside the rectangular screening frame 5, an S-shaped heating copper tube 8 at the bottom of the stainless steel screen 6, rotatable longitudinal baffles 13 at both ends inside the rectangular screening frame 5, and a rotating mechanism for rotating the longitudinal baffles 13 on the outside of the rectangular screening frame 5.

[0032] A moving mechanism for moving the rectangular screening frame 5 is provided on the outside of the crushing box 1;

[0033] The rotating mechanism includes a transverse dual-output shaft motor 9, which is fixed to the outside of the rectangular screening rack 5. The output end of the transverse dual-output shaft motor 9 is rotatably connected to a first transverse transmission column 10 via a pin. The end of the first transverse transmission column 10 away from the transverse dual-output shaft motor 9 is rotatably connected to a transverse rotating column 11 via a pin. A longitudinal rotating rod 12 is fixed inside the top of the transverse rotating column 11. The longitudinal rotating rod 12 passes through the interior of the longitudinal baffle 13 and is fixedly connected to the longitudinal baffle 13.

[0034] The longitudinal rotating rod 12 passes through the interior of the rectangular screening frame 5 and is rotatably connected to the rectangular screening frame 5 through a bearing, so that the longitudinal rotating rod 12 can rotate inside the rectangular screening frame 5, thereby causing the longitudinal baffle 13 to rotate inside the rectangular screening frame 5.

[0035] A second drive motor 4 is bolted to the bottom of the outer side of the crushing box 1. A longitudinal stirring rod 7 is fixed to the output end of the second drive motor 4. Through the operation of the second drive motor 4, the longitudinal stirring rod 7 can rotate, thereby stirring and crushing the particles at the bottom of the crushing box 1.

[0036] Here, a large amount of calcium aluminate granules are poured into the interior of the rectangular screening frame 5 through the feed port 2, and are located on top of the stainless steel screen 6. Smaller granules will fall into the bottom of the crushing box 1 through the stainless steel screen 6. The operation of the second drive motor 4 enables the longitudinal stirring rod 7 to rotate. The rotation of the longitudinal stirring rod 7 enables the granules at the bottom of the crushing box 1 to be crushed. The operation of the transverse double-output shaft motor 9 enables the first transverse transmission column 10 to move. The movement of the first transverse transmission column 10 enables the longitudinal rotating rod 12 to rotate through the transverse rotating column 11. The rotation of the longitudinal rotating rod 12 enables the longitudinal baffle 13 to rotate inside the rectangular screening frame 5. The rotation of the longitudinal baffle 13 can restrict the granules at the top of the rectangular screening frame 5. The operation of the S-shaped heating copper pipe 8 enables the granules at the top of the stainless steel screen 6 to be heated, thereby reducing the moisture inside the blocky calcium aluminate.

[0037] The rotating mechanism includes an L-shaped mounting plate 14, which is located outside the crushing box 1 and is fixedly connected to the crushing box 1. A first drive motor 3 is bolted to one end of the L-shaped mounting plate 14. A second transverse transmission column 16 is fixed to the output end of the first drive motor 3. An L-shaped transverse sliding plate 17 is rotatably connected to one end of the second transverse transmission column 16 via a pin. A longitudinal rotating column 20 is rotatably connected inside the L-shaped transverse sliding plate 17. The longitudinal rotating column 20 is located near the side of the rectangular screening frame 5 and is fixedly connected to the rectangular screening frame 5. The longitudinal rotating column 20 is located inside the crushing box 1 and is movably connected to the crushing box 1.

[0038] A rectangular slider is fixed on the side of the L-shaped horizontal sliding plate 17 near the crushing box 1. A rectangular groove is provided inside the crushing box 1. The L-shaped horizontal sliding plate 17 and the crushing box 1 are slidably connected through the cooperation of the rectangular slider and the rectangular groove. Through the cooperation of the rectangular slider and the rectangular groove, the L-shaped horizontal sliding plate 17 can slide laterally back and forth on the outside of the crushing box 1.

[0039] An inclined hydraulic cylinder 18 is rotatably connected to the outer side of the L-shaped transverse sliding plate 17 via a pin. The output end of the inclined hydraulic cylinder 18 is rotatably connected to a rectangular rotating column 19 via a pin. The top of the rectangular rotating column 19 is fixedly connected to the longitudinal rotating column 20. Through the operation of the inclined hydraulic cylinder 18, the rectangular rotating column 19 can drive the longitudinal rotating column 20 to rotate inside the L-shaped transverse sliding plate 17, thereby enabling the rectangular screening rack 5 to rotate, so that the particles on the top of the rectangular screening rack 5 can fall into the bottom of the crushing box 1.

[0040] Here, the operation of the first drive motor 3 enables the rectangular rotating column 15 to rotate. The rotation of the rectangular rotating column 15 causes the L-shaped transverse sliding plate 17 to move laterally reciprocally outside the crushing box 1 via the second transverse transmission column 16. The movement of the L-shaped transverse sliding plate 17 causes the rectangular screening frame 5 to move laterally reciprocally inside the crushing box 1 via the longitudinal rotating column 20, thereby enabling the blocky calcium aluminate inside the rectangular screening frame 5 to be screened, improving the crushing effect of the blocky calcium aluminate particles. The operation of the inclined hydraulic cylinder 18 causes the longitudinal rotating column 20 to rotate inside the L-shaped transverse sliding plate 17 via the rectangular rotating column 19. The rotation of the longitudinal rotating column 20 enables the angle of the rectangular screening frame 5 to be adjusted, and the rotation of the longitudinal baffle 13 enables the dried particles inside the rectangular screening frame 5 to fall into the bottom of the crushing box 1.

[0041] In use: A large amount of calcium aluminate granules are poured into the interior of the rectangular screening frame 5 through the feed port 2 and are located at the top of the stainless steel screen 6. Smaller granules will fall into the bottom of the crushing box 1 through the stainless steel screen 6. The operation of the horizontal dual-shaft motor 9 enables the first horizontal transmission column 10 to move. The movement of the first horizontal transmission column 10 enables the vertical rotating rod 12 to rotate through the horizontal rotating column 11. The rotation of the vertical rotating rod 12 enables the vertical baffle 13 to rotate inside the rectangular screening frame 5. The rotation of the vertical baffle 13 can restrict the granules at the top of the rectangular screening frame 5. Through the operation of the S-shaped heating copper pipe 8, the granules at the top of the stainless steel screen 6 can be heated, thereby reducing the moisture inside the blocky calcium aluminate.

[0042] The operation of the first drive motor 3 enables the rectangular rotating column 15 to rotate. This rotation, via the second transverse transmission column 16, causes the L-shaped transverse sliding plate 17 to reciprocate laterally outside the crushing chamber 1. The movement of the L-shaped transverse sliding plate 17, via the longitudinal rotating column 20, causes the rectangular screening frame 5 to reciprocate laterally inside the crushing chamber 1, thereby enabling the screening of lumpy calcium aluminate particles inside the rectangular screening frame 5 and improving the crushing effect. The operation of the inclined hydraulic cylinder 18, via the rectangular rotating column 19, causes the longitudinal rotating column 20 to rotate inside the L-shaped transverse sliding plate 17. The rotation of the longitudinal rotating column 20 allows the angle of the rectangular screening frame 5 to be adjusted. The adjustment and rotation of the longitudinal baffle 13 allow the dried particles inside the rectangular screening frame 5 to fall into the bottom of the crushing box 1. The operation of the second drive motor 4 causes the longitudinal stirring rod 7 to rotate, which crushes the particles at the bottom of the crushing box 1. Before crushing, the calcium aluminate is preheated and dried by the S-shaped heating copper pipe 8 to reduce the moisture content of the material and reduce the energy consumption of subsequent crushing. The horizontal reciprocating motion of the rectangular screening frame 5, combined with the angle adjustment of the longitudinal baffle 13, causes the material to tumble on the stainless steel screen 6, preventing the wet and sticky material from clumping together. This makes the dehydrated pre-treated material easier to crush, thereby improving the reaction speed and efficiency of subsequent calcium aluminate processing.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
