Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent processing technology, specifically to a raw material crushing device for water-reducing agents. Background Technology

[0002] Water-reducing agents are commonly used additives in concrete production. Their raw materials are mostly solid granular substances (such as naphthalene-based and polycarboxylate-based raw materials). Before production, they need to be crushed to ensure that the raw material particles reach the preset fineness, so as to ensure the fullness of subsequent dissolution and reaction.

[0003] However, existing crushing devices for water-reducing agent raw materials have a dust extraction pipe installed at the top of one side of the crushing device to reduce the amount of dust inside. This design results in a small dust extraction area inside the crushing device, leading to poor dust extraction efficiency. To address these issues, there is an urgent need for innovative designs based on the existing crushing devices for water-reducing agent raw materials. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This utility model provides a technical solution: a raw material crushing device for water-reducing agents, including a shell 1. A crushing shaft 2 is rotatably mounted on the top center of the shell 1 via a bearing. A driving mechanism is provided on one side of the crushing shaft 2. A crushing rod 3 is fixed to the outer wall of the crushing shaft 2 inside the shell 1. A dust collection mechanism is provided on the crushing shaft 2 to increase the dust collection area inside the shell 1. The dust collection mechanism includes an exhaust pipe 4. The inner side of one end of the exhaust pipe 4 is rotatably mounted on the outer side of the upper end of the crushing shaft 2 above the shell 1 via a sealed bearing. The other end of the exhaust pipe 4 is connected to the input end of an external vacuum cleaner. A first air passage 5 is opened at the top of the crushing shaft 2. A fixing rod 6 is fixed to the top of one side of the crushing shaft 2 inside the shell 1. A second air passage 7 is opened inside the fixing rod 6. The bottom of the rod 6 is provided with a dust suction hole 8. The exhaust pipe 4, the first air passage 5, the second air passage 7 and the dust suction hole 8 are connected to each other in sequence. The dust suction holes 8 are evenly distributed at the bottom of the fixed rod 6. The distance from the end of the fixed rod 6 to the inner side of the outer shell 1 is 2-5cm. The driving mechanism includes a motor 9. The motor 9 is fixed to the top of the outer shell 1. The top output end of the motor 9 is fixed with a first gear 10. A second gear 11 meshes with one side of the first gear 10. The middle part of the second gear 11 is nested and fixedly connected to the outer side of the crushing shaft 2. By starting the motor 9, the fixed rod 6 and the dust suction holes 8 evenly distributed at the bottom of the fixed rod 6 can be rotated, thereby increasing the dust suction area inside the outer shell 1 and improving the dust removal effect inside the outer shell 1. The motor 9 can also drive the crushing rod 3 to rotate to crush the raw materials.

[0016] The crushing rods 3 are distributed at equal angles to the central axis of the crushing shaft 2. The crushing rods 3 are evenly spaced on one side of the crushing shaft 2. The distance from the end of the crushing rod 3 to the inner side of the outer shell 1 is 2-5cm. The distance between adjacent crushing rods 3 is zero, which increases the contact area between the crushing rods 3 and the raw material and improves the crushing effect of the raw material.

[0017] The top of the outer casing 1 is fixed with a protective cover 12 by bolts. One side of the protective cover 12 is fixedly connected to the exhaust pipe 4. The motor 9, the first gear 10 and the second gear 11 are all located inside the protective cover 12. A heat dissipation hole is also provided on one side of the protective cover 12 for heat dissipation of the motor 9. The protective cover 12 protects the motor 9, the first gear 10 and the second gear 11, and also fixes the exhaust pipe 4.

[0018] A feed hopper 13 is fixedly connected to the top side of the outer casing 1. A top cover 14 is threaded onto the top of the feed hopper 13. A discharge pipe 15 is provided at the bottom of the outer casing 1. A manual valve 16 is installed on the discharge pipe 15.

[0019] An air intake pipe is fixedly connected to one side of the top of the outer casing 1. A filter screen is fixed to the upper end of the air intake pipe by bolts to supplement the air volume inside the outer casing 1. The filter screen plays a role in filtering the outside air.

[0020] Working principle: When using the raw material crushing device for water-reducing agent, firstly rotate the top cover 14 off the top of the feed hopper 13, then pour the raw material for preparing the water-reducing agent into the interior of the outer shell 1 through the feed hopper 13, and then reinstall the top cover 14 back onto the top of the feed hopper 13. Next, the motor 9 is started via the handheld controller. The motor 9 drives the first gear 10, the second gear 11, the crushing shaft 2, the crushing rod 3, and the fixing rod 6 to rotate. The crushing rod 3 crushes the raw materials. When the fixing rod 6 rotates, it drives the dust suction holes 8, which are evenly distributed at its bottom, to rotate. Then, the external vacuum cleaner is started. The external vacuum cleaner generates suction at the dust suction holes 8, which causes the dust generated inside the outer shell 1 to enter the interior of the external vacuum cleaner through the dust suction holes 8, the second air passage 7, the first air passage 5, and the exhaust pipe 4, thus completing the recovery of the dust inside the outer shell 1.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
