Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] The drawings will be described below in conjunction with the Figures 1-3 The present application will be further described in detail.

[0032] The embodiments of the present application disclose a material pneumatic mixing system, as shown in Figure 1 and 2 , which comprises a feeding assembly 1 and a mixing assembly 2. The feeding assembly 1 comprises a premixing pipe 12, which first performs preliminary mixing after multiple materials enter. The mixing assembly 2 comprises a mixing bin 21 and a negative pressure separation device 22, which is arranged on the mixing bin 21. The mixing bin 21 is provided with multiple sets of pneumatic devices 4, which are used for blowing air in the mixing bin 21, so that the materials in the mixing bin 21 are mixed under the action of the air.

[0033] As shown in Figure 1 and 2 , the feeding assembly 1 further comprises a feeding pipe 11, which is provided with no less than two, which is set according to the types of raw materials required by actual production and processing. The feeding pipe 11 is connected with the premixing pipe 12, and the end of the premixing pipe 12 away from the feeding pipe 11 is fixedly connected with the negative pressure separation device 22, so that the raw materials are moved to the negative pressure separation device 22 and the mixing bin 21 through the premixing pipe 12 under the guidance of the negative pressure air flow. After multiple raw material materials enter the premixing pipe 12, they are mixed while being conveyed under the guidance of the negative pressure air flow, and are premixed before entering the mixing bin 21.

[0034] As shown in Figure 2 and 3As shown, the pneumatic device 4 includes a connecting plate 41, a pneumatic pipe 42 and a pneumatic driving source, the connecting plate 41 is fixedly connected to the bottom of the mixing bin 21, the pneumatic driving source (not shown in the figure) is fixedly connected to the outer wall of the mixing bin 21, the connecting plate 41 is provided with a connecting hole 411 which is in communication with the pneumatic pipe 42, the pneumatic pipe 42 is connected with the pneumatic driving source, and the pneumatic driving source blows air into the connecting hole 411, i.e. the inside of the mixing bin 21, through the pneumatic pipe 42 when the pneumatic driving source is running, so as to pneumatically mix the various raw materials in the mixing bin 21.

[0035] As shown in Figure 2 and 3 , the pneumatic device 4 further includes a sealing member, the sealing member includes a sealing cylinder 43 and a sealing block 44, the sealing cylinder 43 is fixedly connected to the outer side of the pipe wall of the pneumatic pipe 42, the piston rod of the sealing cylinder 43 extends into the pneumatic pipe 42, and the sealing block 44 is fixed to the end of the piston rod of the sealing cylinder 43. When the pneumatic driving source is working, the sealing cylinder 43 drives the sealing block 44 to extend out, so as to make room for the connecting hole 411, so that the connecting hole 411 is in communication with the inside of the mixing bin 21, so that the airflow smoothly enters the inside of the mixing bin 21 through the pneumatic pipe 42 and the connecting hole 411; when the material needs to be discharged after being mixed, the sealing cylinder 43 drives the sealing block 44 to move and block the connecting hole 411, so as to prevent the connecting hole 411 from being blocked by the material when the material is moving out.

[0036] As shown in Figure 1 and 3 , the mixing assembly 2 further includes a discharging pipe 23, a discharging valve 24 and a backflow pipe 25, the discharging pipe 23 is connected below the mixing bin 21, the discharging valve 24 is arranged on the discharging pipe 23, one end of the backflow pipe 25 is fixedly connected with the discharging valve 24, and the other end is connected with the negative pressure separation device 22. The pneumatic device 3 is arranged on the discharging pipe 23, and the mixed material moves out through the discharging pipe 23, and in the process of moving out, the material is blown and mixed again through the pneumatic device 3, so as to further improve the uniformity of the material mixing. If the uniformity of the material mixing does not reach the standard, the material is backflowed to the mixing bin 21 again through the backflow pipe 25, at this time, the material originally at the bottom of the mixing bin 21 is at the upper part of the mixing bin 21 after being guided by the backflow of the backflow pipe 25, so that the material changes position and is further mixed.

[0037] As shown in Figure 1 , the mixing assembly 2 further includes a sampler 5, a discharging bin 28 and a discharging pipe 27, the sampler 5 is fixedly connected to the outer wall of the mixing bin 21, and the sampler 5 randomly samples the mixed material in the mixing bin 21, so as to facilitate the operator to observe the material mixing condition in the mixing bin 21. The backflow pipe 25 is provided with a three-way connecting valve 26, the three-way connecting valve 26 is connected with the discharging pipe 27, and the discharging bin 28 is connected to the end of the discharging pipe 27 away from the three-way connecting valve 26.

[0038] After the raw materials in the mixing bin 21 are pneumatically mixed for a period of time, the mixing bin 21 is randomly sampled by the sampler 5 to observe whether the material mixing meets the design standard. If the mixing standard is met, the material can enter the discharge bin 28. The discharge facilitates subsequent packaging and other operations. If the mixing standard is not met, the three-way connection valve 26 connects the return pipe 25 with the negative pressure separation device 22, and the material moves from the discharge bin 28 to the negative pressure separation device 22 through the downpipe 23 and the return pipe 25, and then enters the mixing bin 21 again for pneumatic mixing.

[0039] The implementation principle of the material pneumatic mixing system in the embodiment of the application is as follows:

[0040] The various raw materials enter the premixing pipe 12 through the feeding pipe 11 for preliminary mixing. The preliminarily mixed material moves to the mixing bin 21 under the action of negative pressure, and is further mixed and stirred under the blowing action of the pneumatic device 4. The various materials are mixed and stirred by the system, so that the mixing of the materials is more sufficient and uniform. In the running process, the sampler 5 can also be used to sample and spot check the mixed material in the mixing bin 21 to observe whether the mixing is in place, and then to determine whether the material needs to be mixed again by the return method. Compared with the mechanical stirring method, the pneumatic mixing method makes the mixing of the materials more uniform and efficient.

[0041] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the application should be covered within the protection scope of the application.
