Abstract
Description
Technical Field

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] The impact-resistant, modular toy uniform mixing device disclosed in this utility model is mainly used in scenarios where the stability of current mixing devices is not high and the mixing efficiency is low.
[0021] Reference Figures 1-4 An impact-resistant, modular toy uniform mixing device includes: a base platform 1, with three circumferentially spaced uprights 2 fixedly connected to the upper side of the base platform 1, and the same top platform 3 fixedly connected to the upper ends of the three uprights 2; a mixing drum 4, which is rotatably connected between the base platform 1 and the top platform 3 via bearings, and has a discharge port and valve on its lower side, and is used to mix raw materials; a pre-crushing drum 5, with a circular hole in the middle of both the base platform 1 and the top platform 3, and the pre-crushing drum 5 is fixedly connected to the circular hole of the base platform 1 and the top platform 3, located inside the mixing drum 4, and the outer wall of the mixing drum 4 is rotatably connected to the pre-crushing drum 5 via bearings; and a pre-treatment component 6, which is disposed on the pre-crushing drum 5, and is used to crush and screen the raw materials.
[0022] The device adopts a combination of a pre-crushing drum 5 and a mixing drum 4, which can crush, screen and mix raw materials, effectively reducing the impact of large particles in the raw materials during the mixing process. It uses air blowing to screen and transport the raw materials, further improving the uniformity of the raw material mixing and shortening the mixing time. The integrated design combines preliminary crushing, screening and mixing functions. Compared with the current mixing equipment, the integrated function is more conducive to raw material processing. The integrated equipment also helps to save overall costs and reduce the space occupation caused by the use of multiple equipment.
[0023] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the pre-processing assembly 6 includes: a pre-shaft 601 located inside the pre-crushing cylinder 5, with a spiral blade 602 fixedly connected to the outside of the pre-shaft 601, the spiral blade 602 being located at the lower end of the pre-shaft 601; a plurality of crushing rods 603 fixedly connected to the spiral blade 602, the plurality of crushing rods 603 being spirally and equidistantly distributed on the spiral blade 602; a plurality of feed inlets 604 disposed on the pre-crushing cylinder 5 and equidistantly distributed around the circumference, the feed inlets 604 communicating with the inner cavity of the pre-crushing cylinder 5 and the inner cavity of the mixing cylinder 4; and a plurality of anti-backflow cover plates 605 fixedly connected to the outer wall of the pre-crushing cylinder 5, the plurality of anti-backflow cover plates 605 being respectively located outside the plurality of feed inlets 604.
[0024] In this scheme, the pre-processing component 6 is expected to include: an air distributor 606, which is fixedly connected to the lower end of the pre-crushing cylinder 5. The air outlet of the air distributor 606 is connected to the inner cavity of the pre-crushing cylinder 5, and a conical guide shroud 609 is provided above the air outlet. The conical guide shroud 609 has multiple airflow distribution holes. The airflow distribution holes on the conical guide shroud 609 can make the airflow evenly dispersed and prevent the raw materials from directly settling at the air outlet; a blower 607, which is fixedly connected to the upper side of the base platform 1. The output port of the blower 607 is fixedly connected to an air supply pipe 608, and the other end of the air supply pipe 608 is connected to the air inlet of the air distributor 606.
[0025] Specifically, the pre-processing component 6 is suitable for the crushing and screening of raw materials. The pre-processing component 6 uses a high-speed rotating crushing rod 603 to crush and initially mix the raw materials in the pre-crushing cylinder 5, and uses an upward blowing method to screen the crushed raw materials, so that the raw materials that meet the particle size requirements enter the mixing cylinder 4, avoiding the internal impact caused by the impact of excessively large raw material particles in the mixing cylinder 4 during stirring. The crushing process and the blowing feeding process of the raw materials in the pre-crushing cylinder 5 can both perform preliminary mixing of the raw materials, preventing the raw materials from being directly added into the mixing cylinder 4 and causing local accumulation of raw materials, effectively improving the uniform mixing effect of the raw materials and shortening the mixing time of the raw materials. The spiral blade 602 can guide the upward airflow in the pre-crushing cylinder 5, so as to form a spiral upward airflow inside, thereby improving the mixing and conveying effect of the crushed raw materials. The anti-backflow cover 605 can ensure that the airflow entering the mixing cylinder 4 is in a downward conveying state, thereby effectively preventing the raw materials from flowing back into the pre-crushing cylinder 5.
[0026] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a top frame 7 is fixedly connected to the upper end of the pre-crushing cylinder 5. The top frame 7 is fixedly connected to the upper surface of the top platform 3, and a feeding bin 8 is provided on the top frame 7. The feeding bin 8 communicates with the inner cavity of the pre-crushing cylinder 5.
[0027] Specifically, the initial raw material is added to the pre-crushing cylinder 5 from the feeding hopper 8. The feeding hopper 8 is equipped with a cover, which can seal the pre-crushing cylinder 5 during the pre-processing.
[0028] Reference Figure 1 and Figure 3 In a preferred embodiment, a pre-crushing motor 9 is fixedly connected to the upper side of the top frame 7, and the output end of the pre-crushing motor 9 is connected to a rotating shaft via a coupling. The rotating shaft is fixedly connected to the pre-shaft 601.
[0029] Reference Figure 1 and Figure 2 In a preferred embodiment, a plurality of stirring rods 10 are fixedly connected to the inner wall of the stirring cylinder 4. Each set of stirring rods 10 includes a plurality of stirring rods 10 that are equidistant from top to bottom, and an exhaust strip 11 is provided on the upper side of the stirring cylinder 4.
[0030] Specifically, the mixing drum 4 rotates in the opposite direction to the pre-crushing shaft 601. There are clockwise and counterclockwise rotational traction forces inside the crushing and mixing device, which can cancel each other out, thereby reducing the instability of the device and effectively reducing the impact effect of the raw materials inside the drum. After the blown material enters the mixing drum 4, since the inner cavity of the mixing drum 4 is much larger than the inner cavity of the pre-crushing drum 5, the gas will be discharged through the exhaust strip 11. At this time, the raw materials inside cannot move upward and be discharged with the gas. At the same time, the gas entering the mixing drum 4 will form a turbulent airflow inside the mixing drum 4, disturbing the raw materials inside and further improving the mixing effect.
[0031] Reference Figure 1 and Figure 2 In a preferred embodiment, a ring gear 12 is fixedly connected to the outside of the stirring drum 4, and a stirring motor 13 is fixedly connected to a stand 2. The output end of the stirring motor 13 is connected to a shaft through a coupling, and a drive gear 14 is fixedly connected to the upper end of the shaft. The drive gear 14 meshes with the ring gear 12.
[0032] Working principle: During use, the initial raw material is added to the pre-crushing cylinder 5 from the feeding bin 8; in the pre-crushing cylinder 5: the pre-crushing motor 9 drives the pre-shaft 601 to rotate at high speed, the crushing rod 603 crushes and initially mixes the initial raw material in the pre-crushing cylinder 5, the blower 607 delivers gas to the air distributor 606 through the air pipe 608, and the air distributor 606 blows air upward from the lower end of the pre-crushing cylinder 5 (here the conical guide shroud 609 can guide the raw material to the cylinder wall area of the pre-crushing cylinder 5, forming a high-speed rotation with the spiral blade 602). With the negative pressure zone in place, continuous conveying is achieved under the influence of the spiral rising airflow, preventing particles from accumulating above the air distributor 606. The crushed initial raw material moves with the upward airflow and enters the mixing drum 4 through the feed inlet 604. In the mixing drum 4, the mixing motor 13 drives the drive gear 14 to rotate and mesh with the ring gear 12, causing the mixing drum 4 to rotate (the rotation direction of the mixing drum 4 is opposite to the rotation direction of the feed shaft 601). The mixing rod 10 mixes and stirs the raw material in the mixing drum 4.
[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
