In the past, people regarded aluminum slag as waste slag and dumped it, which not only caused a waste of aluminum resources but also brought environmental problems. Therefore, finding economical and effective methods to utilize and manage aluminum slag will not only improve the economic benefits of the aluminum industry, but also have an important impact on achieving sustainable economic and social development while achieving effective recycling of resources.
[0003] Homogenizing equipment is a necessary equipment in the process of dry cement manufacturing. It can stabilize the composition of raw materials entering the kiln. The significance of stabilizing the composition of raw materials is to burn the clinker stably, so homogenizing equipment is also the basic equipment of cement production plants. Homogenizing equipment generally uses air stirring when working. When the raw material powder is discharged downward, it is fully mixed. The use of air in different flow directions makes the material surface tilt, and finally achieves the purpose of radial mixing and homogenization.
[0004] In the process of realizing the present utility model, the inventors found that the prior art had the following problems: 1.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1 to 6The utility model provides a technical solution: a powder material homogenizing device that is convenient for reducing dust dispersion, including a top cover 1, the bottom of the top cover 1 is inserted into the inner wall of a box body 2, a main feed port 3 is welded on one side of the top of the box body 2, and an auxiliary feed port 4 is welded on the other side of the top of the box body 2, the bottom end of the main feed port 3 is threadedly connected with a feed pipe A5, and the bottom end of the auxiliary feed port 4 is threadedly connected with a feed pipe B6, the bottom ends of the feed pipes A5 and B6 are both inserted into the top of a homogenizing chamber 7, an inflation mechanism 8 is provided in the middle of the bottom of the homogenizing chamber 7, a discharge port 9 is provided on one side of the bottom of the homogenizing chamber 7, and a dust suction mechanism 10 is provided on the inner wall of one side of the box body 2 located directly above the homogenizing chamber 7.
[0023] In this embodiment, Figure 5 As shown, the feed pipe A5 and the feed pipe B6 are relatively inclined, and the bottom ends of the two are connected to each other to form a main feed pipe. It should be noted that the operator can first put different powdered materials into the main feed port 3 and the auxiliary feed port 4 respectively, so that the different powdered materials are transported along the feed pipe A5 and the feed pipe B6 to the main feed pipe where the bottom ends of the two are combined. During this period, the two different powdered materials are simultaneously transported to the inside of the same main feed pipe. Therefore, when the two powdered materials meet, they are preliminarily mixed, and then these powdered materials will be transported to the inside of the homogenization chamber 7 through the main feed pipe again, so as to perform more detailed mixing and homogenization operations.
[0024] In this embodiment, Figure 2 and Figure 4 As shown, the homogenizing chamber 7 is provided with a filter screen 701 just below the main feed pipe. It should be noted that after the powdered material is initially mixed and transported to the inside of the homogenizing chamber 7 through the main feed pipe, it will first fall onto the surface of the filter screen 701, rather than directly falling to the bottom of the homogenizing chamber 7 and being concentrated and stationary. During this period, the operator can start the vibration motor to drive the entire filter screen 701 to start shaking. At the same time, the powdered material falling on the surface of the filter screen 701 will also be excited to fly around in the homogenizing chamber 7. At the same time, the inflation mechanism 8 is started to transport compressed air to the inside of the homogenizing chamber 7, so that different types of powdered materials are blown and evenly mixed with each other, and the mixing quality is also higher, and the powdered materials are effectively prevented from sinking to the bottom due to gravity.
[0025] In this embodiment, Figure 4As shown, a vibration motor is fixedly installed on one side of the bottom of the filter screen 701; it should be noted that when different powdered materials are transported to the interior of the homogenizing chamber 7 through the main feed pipe, they will first fall onto the surface of the filter screen 701. At this time, the operator can start the vibration motor fixedly installed at the bottom of the filter screen 701 through an external controller, so that the vibration motor starts to vibrate, and drives the entire filter screen 701 in contact with it to start vibrating. At this time, the powdered materials falling on the surface of the filter screen 701 will also be excited to start shaking and fly around inside the homogenizing chamber 7. At the same time, the operator can start the inflation mechanism 8 to transport compressed air to the interior of the homogenizing chamber 7, blowing it into the interior of the homogenizing chamber 7, thereby mixing and homogenizing the powdered materials inside. During this process, the powdered materials that have completed mixing and homogenization will fall along the holes on the surface of the filter screen 701 to the discharge port 9 provided on one side of the bottom of the homogenizing chamber 7, and be discharged smoothly therefrom.
[0026] In this embodiment, Figure 1 and Figure 3 As shown, the inflation mechanism 8 is composed of an air outlet 801, an air pump 802, a dustproof mesh cover 803 and a connecting pipe 804. One end of the connecting pipe 804 is connected to the inflation port of the external air pump 802, and the other end is connected to the air outlet 801 through the bottom of the homogenizing chamber 7. At the same time, a dustproof mesh cover 803 is also provided on the top of the air outlet 801. It should be noted that when the operator starts the vibration motor, the various powdered materials that fall onto the surface of the filter screen 701 are simultaneously aroused to shake and begin to fly around. At the same time, the air pump 802 can be started to The compressed air is delivered to the air outlet 801 at the other end through the connecting pipe 804 connected to the inflation port, and the compressed airflow is delivered to the interior of the homogenizing chamber 7 through the mesh holes on the surface of the dustproof mesh cover 803. At the same time, the powdered materials in the homogenizing chamber 7 will be blown up by the compressed airflow and mixed with each other. At the same time, with the joint action of the vibration motor, different powdered materials can be better homogenized. The dustproof mesh cover 803 provided at the air outlet 801 can effectively prevent the powdered materials from passing through the air outlet 801 and falling into the interior of the connecting pipe 804.
[0027] In this embodiment, Figure 6As shown, the dust suction mechanism 10 is composed of an air suction machine 1001, a return pipe 1002 and a protection box 1003. The protection box 1003 is threadedly connected to one side of the inner wall of the box body 2, and the air suction machine 1001 is placed inside the protection box 1003. At the same time, a return pipe 1002 is provided on one side of the protection box 1003 that is attached to the inner wall of the box body 2, and one end of the return pipe 1002 passes through the inner wall of the box body 2 horizontally, and the other end passes through the interior of the homogenization chamber 7; it should be noted that when the inflation mechanism 8 delivers compressed air to the interior of the homogenization chamber 7 and the powdery materials are mixed with each other through the joint action of the vibration motor, the powdery state of the material itself may cause dust to fly and it may be difficult to fall and stand still. Therefore, the utility model is provided with a dust suction mechanism 10 at the inner wall of one side of the box body 2 located directly above the homogenization chamber 7. While performing the homogenization operation, the operator can simultaneously start the vacuum fan 1001 inside the protection box 1003 through the external controller, so that the vacuum fan 1001 absorbs the powdered materials scattered inside the homogenization chamber 7 into the protection box 1003 through the holes opened in the protection box 1003, and then absorbs them into the return pipe 1002 provided on one side of the protection box 1003. Because one end of the return pipe 1002 is connected to the protection box 1003, and the other end thereof is interconnected with the interior of the homogenization chamber 7, the powdered materials absorbed into the return pipe 1002 will re-enter the homogenization chamber 7 under the drive of the vacuum fan 1001 for mixing and homogenization operations, and after multiple cycles of vacuuming, the powdered materials sucked into the return pipe 1002 will also become mixed evenly, so that the powdered materials can be mixed more fully.
[0028] The use method and advantages of the utility model: The powder material homogenizing equipment which is convenient for reducing dust dispersion, when in use, the working process is as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, first, the operator puts different powdered materials into the main feed port 3 and the auxiliary feed port 4 respectively, and they are transported to the main feed pipe along the feed pipe A5 and the feed pipe B6 connected to the bottom ends of the two feed ports respectively. The different powdered materials entering the main feed pipe together are preliminarily mixed inside the pipe, and then enter the interior of the homogenization chamber 7 through the main feed pipe, and directly fall on the surface of the filter screen 701 arranged directly below it. At the same time, the operator can start the vibration motor, so that the vibration motor drives the entire filter screen 701 to vibrate together. At this time, the powdered materials falling on the surface of the filter screen 701 will also shake and fly away. At this time, the operator starts the air pump 802 to pump air into the homogenization chamber 7 through the connecting pipe 804. The compressed air flow is transported inside the homogenizing chamber 7, and the compressed air flow is blown toward the powdered materials inside the homogenizing chamber 7, so that the powdered materials are blown and mixed with each other. During this process, in order to prevent the powdered materials from being dispersed in large quantities, the operator can simultaneously start the vacuum fan 1001 in the dust suction mechanism 10 to suck the floating powder flying around into the interior of the protection box 1003, and transport it to the bottom of the homogenizing chamber 7 again through the reflux pipe 1002 on one side of the protection box 1003, so as to perform a more sufficient homogenization operation. After completing the homogenization of various powdered materials, the vacuum fan 1001 can be started again to suck the powder still in a dispersed state into the protection box 1003, and transport it to the bottom of the homogenizing chamber 7 through the reflux pipe 1002, and then discharge it from the discharge port 9.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
