Description

Technical Field

[0001] The utility model relates to the technical field of stearic acid production, and particularly relates to a mixing mechanism for magnesium stearate powder. Background Art

[0002] In recent years, stearates have been widely used. Stearates are widely used in various industries such as petrochemical, daily chemical, plastic rubber, paint and coating, etc. They are mainly used as heat stabilizers for the processing of polymer materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc., and lubricants and dispersants in industries such as paints and coatings. Magnesium stearate mainly exists in the form of powder in the stearate market. A large amount of dust will be generated during the production, packaging and use of powder products, and dust pollution is extremely likely to occur during transportation and customer feeding. Therefore, with the development of the industry and the improvement of people's environmental protection awareness, the process of improving powdery magnesium stearate into granular form has received more and more attention. Replacing powdery products is the trend and direction of future development. When making magnesium stearate into granular form, an appropriate amount of binder needs to be added to the magnesium stearate powder and mixed evenly, and then the mixed material is made into granular form by wet granulation or dry granulation methods. However, in the prior art, magnesium stearate and the binder are added into the mixing mechanism together for mixing. Since the addition amount of the binder is small, in order for the mixing mechanism to completely mix the two evenly, a longer mixing time is required, which significantly reduces the production efficiency of magnesium stearate particles. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a mixing mechanism for magnesium stearate powder to solve the above deficiencies in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A mixing mechanism for magnesium stearate powder, comprising: a stirring barrel, a rotating shaft is rotatably arranged in the stirring barrel, a stirring paddle is fixedly connected to the bottom end of the rotating shaft, a feeding disk and a material distributing hopper are fixedly sleeved outside the rotating shaft, a material blocking partition is fixedly connected in the stirring barrel, the material blocking partition is located between the material distributing hopper and the feeding disk, and the bottom end of the feeding disk is attached to the top end of the material blocking partition. A material passing opening is formed on the material blocking partition. As the rotating shaft rotates, the materials are evenly spread in the feeding disk and gradually fall onto the material distributing hopper through the material passing opening.

[0005] Further, the feeding disk is composed of an inner ring, an outer ring and a plurality of partitions, and the area between the inner ring and the outer ring is divided into a plurality of equal parts by the plurality of partitions.

[0006] Further, a plurality of material passing holes are formed on the material distributing hopper, and a material blocking ring is connected to the periphery of the material distributing hopper through four fixing blocks.

[0007] Furthermore, a barrel cover is threadedly connected to the top of the mixing barrel, and a first feed pipe and a second feed pipe are provided on the barrel cover. The connection point between the first feed pipe and the second feed pipe and the mixing barrel is located directly above the feeding tray.

[0008] Furthermore, the size of the feed opening is slightly larger than the size of an equally divided area on the feed tray.

[0009] In the above technical solution, the magnesium stearate powder mixing mechanism provided by the present invention has the following beneficial effects:

[0010] The utility model drives the feeding disc to rotate by the rotating shaft, so that the magnesium stearate and the binder are respectively and evenly sprinkled into the feeding disc, thereby improving the mixing efficiency of the magnesium stearate and the binder. As the feeding disc rotates, the material in the feeding disc evenly falls onto the distribution hopper through the feeding port. As the distribution hopper rotates, the material slides down along the slope of the distribution hopper under the action of the centrifugal force generated by the distribution hopper and the gravity of the magnesium stearate and the binder themselves. The magnesium stearate and the binder gradually fall into the stirring area of the stirring barrel through the feeding hole, further improving the mixing efficiency of the magnesium stearate and the binder. Then, before the magnesium stearate and the binder are stirred and mixed, the magnesium stearate and the binder are mixed together in advance, thereby greatly accelerating the mixing efficiency of the magnesium stearate and the binder.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0021] Please refer to FIGS. 1-4. A magnesium stearate powder mixing mechanism includes: a stirring barrel 1, a rotating shaft 9 is rotatably arranged in the stirring barrel 1, a stirring paddle 4 is fixedly connected to the bottom end of the rotating shaft 9, a feeding tray 7 and a distributing hopper 5 are fixedly sleeved outside the rotating shaft 9, the distributing hopper 5 and the feeding tray 7 rotate with the rotation of the rotating shaft 9, a blocking baffle 6 is fixedly connected in the stirring barrel 1, a round hole 62 is formed in the middle area of the blocking baffle 6, the rotating shaft 9 passes through the material passing opening 61 and then is connected to the stirring paddle 4, the blocking baffle 6 is located between the distributing hopper 5 and the feeding tray 7, and the bottom end of the feeding tray 7 is attached to the top end of the blocking baffle 6. A material passing opening 61 is formed in the blocking baffle 6, so that the feeding tray 7 can push the magnesium stearate and the binder scattered on the top end of the blocking baffle 6 towards the material passing opening 61. With the rotation of the rotating shaft 9, the materials are evenly distributed in the feeding tray 7 and gradually fall onto the distributing hopper 5 through the material passing opening 61.

[0022] Specifically, in the present utility model, the rotating shaft 9 drives the feeding tray 7 to rotate, so that the magnesium stearate and the binder are evenly distributed into the feeding tray 7 respectively, improving the mixing efficiency of the magnesium stearate and the binder. With the rotation of the feeding tray 7, the materials in the feeding tray 7 evenly fall onto the distributing hopper 5 through the material passing opening 61. With the rotation of the distributing hopper 5, under the centrifugal force generated by the distributing hopper 5 and the self-gravity of the magnesium stearate and the binder, they slide down along the slope of the distributing hopper 5, and the magnesium stearate and the binder gradually fall into the stirring area of the stirring barrel 1 through the material passing holes 51, further improving the mixing efficiency of the magnesium stearate and the binder. Then, before the magnesium stearate and the binder are stirred and mixed, the magnesium stearate and the binder are premixed together, greatly accelerating the mixing efficiency of the magnesium stearate and the binder.

[0023] Further, the feeding tray 7 is composed of an inner ring, an outer ring and a number of partition plates, and a number of partition plates divide the area between the inner ring and the outer ring into multiple equal parts.

[0024] Specifically, referring to Figure 3 , magnesium stearate and the binder are successively sprinkled into the feeding tray 7, and the spreading amount of magnesium stearate and the binder per unit time is determined by the ratio of magnesium stearate to the binder, so that there is a small amount of magnesium stearate and the corresponding ratio of the binder in the evenly divided areas on the feeding tray 7, which is convenient for the mixing of magnesium stearate and the binder.

[0025] Further, a number of material passing holes 51 are formed in the material distributing hopper 5, and a baffle ring 52 is connected to the periphery of the material distributing hopper 5 through four fixing blocks 53. The material distributing hopper 5 and the fixing blocks 53 are welded, and the fixing blocks 53 and the baffle ring 52 are welded.

[0026] Specifically, referring to Figure 4 , magnesium stearate and the binder are divided into portions and fall onto the material distributing hopper 5 through the material passing port 61. As the material distributing hopper 5 rotates, magnesium stearate and the binder slide down along the slope of the material distributing hopper 5 under the action of centrifugal force and their own gravity, and then gradually fall into the stirring area of the stirring barrel 1 through the material passing holes 51 to participate in stirring. The magnesium stearate and the binder that do not fall into the stirring barrel 1 through the material passing holes 51 fall into the stirring area of the stirring barrel 1 through the gap between the material distributing hopper 5 and the baffle ring 52 to participate in stirring.

[0027] Further, the top end of the stirring barrel 1 is threadedly connected with a barrel cover 2, and a first feed pipe 11 and a second feed pipe 12 are arranged on the barrel cover 2. The connection parts of the first feed pipe 11 and the second feed pipe 12 with the stirring barrel 1 are located directly above the feeding tray 7.

[0028] Specifically, magnesium stearate and the binder enter the stirring barrel 1 through the first feed pipe 11 and the second feed pipe 12 respectively, so that magnesium stearate and the binder are sprinkled in the feeding tray 7.

[0029] Further, the size of the material passing port 61 is slightly larger than the size of an equal division area on the feeding tray 7.

[0030] Specifically, referring to Figure 2 , the size of the material passing port 61 is larger than the size of an equal division area on the feeding tray 7, so that the magnesium stearate and the binder in the feeding tray 7 are completely pushed into the material passing port 61 portion by portion.

[0031] In the present utility model, referring to Figures 1 to 4, first, magnesium stearate and the binder are proportionally conveyed into the mixing barrel 1 through the first feed pipe 11 and the second feed pipe 12. As the motor 3 drives the rotating shaft 9 to rotate, the feeding disk 7 rotates relative to the first feed pipe 11 and the second feed pipe 12. The magnesium stearate and the binder entering from the first feed pipe 11 and the second feed pipe 12 are evenly spread in the feeding disk 7 and then pushed into the feeding port 61, so that the magnesium stearate and the binder are scattered portion by portion towards the distributing hopper 5. Then, with the rotation of the distributing hopper 5, under the action of the centrifugal force generated by the distributing hopper 5 and the self-gravity of the magnesium stearate and the binder, they slide down along the slope of the distributing hopper 5. The magnesium stearate and the binder gradually fall into the mixing area of the mixing barrel 1 through the feeding holes 51 to participate in the mixing. The magnesium stearate and the binder that are not spread into the mixing barrel 1 through the feeding holes 51 fall into the mixing area of the mixing barrel 1 through the gap between the distributing hopper 5 and the baffle ring 52 to participate in the mixing, greatly accelerating the mixing efficiency of the magnesium stearate and the binder.

[0032] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
