[0034] The technical scheme of the utility model will be further illustrated below by combining the drawings and through specific embodiments.
[0035] As Figures 1 to 5 shown, the utility model embodiment provides a flour automatic screening device, including frame 1, feed tank 2, vibrating screen 3, cloth bag adsorption assembly 4, tee drop pipe 5 and material blocking mechanism 6;
[0036] The feed tank 2 is arranged on the frame 1, the feed tank 2 is provided with a box door 21, the box door 21 is connected with the feed tank 2 through the gas spring 22, and the feed tank 2 has a containing cavity 20; the box door 21 and the feed tank 2 are connected through the gas spring 22, which can facilitate the user to open the box door 21 to feed into the containing cavity 20, after feeding is completed, the box door 21 can be closed to prevent flour from flying, improve the working environment of the workshop, and reduce the harm of dust to the health of workers.
[0037] As Figure 1 and Figure 2As shown, the vibrating screen 3 comprises a vibrating motor 31, a first shell 32, a spring 33 and a screen mesh 34, the first shell 32 is connected with the rack 1 through the spring 33 at the bottom, the vibrating motor 31 is arranged on the side wall of the first shell 32, the vibrating motor 31 is used to drive the first shell 32 to vibrate, the screen mesh 34 is arranged on the top of the first shell 32, and the screen mesh 34 is located in the accommodating cavity 20; when the vibrating motor 31 drives the first shell 32 to vibrate, the screen mesh 34 is also shaken, so that the smaller particles in the flour are screened through the holes of the screen mesh 34, and the larger particles of the flour are left on the screen mesh 34 and continue to be separated by the vibrating screen 3 until they are separated from the screen mesh 34.
[0038] As shown in Figure 2 The cloth bag adsorption assembly 4 is arranged above the accommodating cavity 20, and is used to adsorb the floating powder in the accommodating cavity 20; during the flour feeding process, the fine powder is easy to float in the air to form dust, and the cloth bag adsorption assembly 4 is arranged above the accommodating cavity 20, so that the floating dust can be adsorbed to prevent it from spreading to the external environment, thereby reducing the dust concentration in the air.
[0039] As shown in Figure 4 and Figure 5 The three-way feeding pipe 5 has a feeding pipe 50, a first discharging pipe 51 and a second discharging pipe 52, the feeding pipe 50 is communicated with the bottom of the first shell 32, the first discharging pipe 51 and the second discharging pipe 52 are respectively communicated with the bottom of the feeding pipe 50 on both sides, the blocking mechanism 6 is arranged in the feeding pipe 50, and the blocking mechanism 6 is used to switch to block the first discharging pipe 51 or the second discharging pipe 52. Through the blocking mechanism 6, the discharging pipeline of the flour can be switched and adjusted to adapt to the processing of different types of flour.
[0040] As shown in Figures 1 to 3As shown, further, the cloth bag adsorption assembly 4 includes an adsorption cloth bag 41, a second housing 42, a negative pressure fan 43, and a pulse blower 44. The second housing 42 is arranged on the top of the feeding box 2. The adsorption cloth bag 41 is partially located in the accommodation chamber 20 and connected with the second housing 42. The negative pressure fan 43 is arranged on the second housing 42 and communicates with the adsorption cloth bag 41. The negative pressure fan 43 is used to generate a negative pressure suction force on the adsorption cloth bag 41. The pulse blower 44 is arranged at the side end of the second housing 42 and connected with the adsorption cloth bag 41 through a pipeline. The pulse blower 44 is used to generate a blowing gas on the adsorption cloth bag 41. When the flour is fed, the negative pressure fan 43 can generate a negative pressure suction force through communication with the adsorption cloth bag 41 to suck the dust in the accommodation chamber 20 onto the surface of the adsorption cloth bag 41, preventing the fine dust from being scattered to the outside and avoiding dust pollution. After the box door 21 is closed to complete the feeding, the pulse blower 44 is started to inject a high-pressure gas into the adsorption cloth bag 41, so as to blow the dust adsorbed on the adsorption cloth bag 41 to the filter screen for screening and filtering.
[0041] As shown in Figure 4 and Figure 5 As shown, further, the material blocking mechanism 6 includes a push air cylinder 61, a swing arm 62, a rotating shaft 63, and a blocking plate 64.

The push air cylinder 61 is used to push the rotating shaft 63 to rotate, so as to swing the blocking plate 64 along the area between the first discharging pipe 51 and the second discharging pipe 52. The material blocking mechanism 6 can adjust the discharging direction of the flour. Specifically, the push air cylinder 61 can drive the rotating shaft 63 to rotate through the swing arm 62, so as to change the relative position of the blocking plate 64. When the blocking plate 64 is rotated to the side of the pipe opening of the first discharging pipe 51, the blocking plate 64 blocks the first discharging pipe 51, so that the flour can be discharged through the second discharging pipe 52. Conversely, the same is true.
[0042] As shown in Figure 1 and Figure 2 As shown, further, the bottom of the feeding box 2 has an inclined slope structure 200. The height of the inclined slope structure 200 gradually decreases away from the box door 21. In this way, the flour can naturally slide downward under the action of gravity during the feeding process, so as to facilitate the flour material to smoothly enter the screen 34 for screening treatment, thereby improving the flour screening efficiency.
[0043] As shown in Figure 4As shown, further, the first discharge pipe 51 and the second discharge pipe 52 are respectively provided with electric butterfly valves 53, the electric butterfly valves 53 can adjust the opening angle of the valve, thereby controlling the discharging flow of the powder, avoiding the interference of the too fast or too slow material flow rate to the downstream process.
[0044] Further, the adsorption cloth bag 41 is made of polyester fiber material. The polyester fiber material has high filtering efficiency, which can effectively capture and adsorb the fine dust particles generated in the feeding process.
[0045] As shown, Figure 3 Further, the number of the adsorption cloth bag 41 is two, which can improve the adsorption capacity of the dust by increasing the filtering area, and effectively reduce the dust overflow.
