Description

Technical Field

[0001] This utility model relates to the field of agricultural and grain machinery technology, and in particular to a dual-air duct Sacron air supply mechanism for cleaning screens. Background Technology

[0002] A vibrating screen works by using the reciprocating rotary vibration generated by the vibrator. The rotating weight on the upper part of the vibrator causes the screen surface to vibrate in a planar circular motion. The vibrating screen is equipped with screens of various mesh sizes to separate impurities of various sizes from the grain. Currently, in order to prevent the vibrating screen from clogging and to increase the screening effect, air is usually blown into the screen through an air supply mechanism to separate the grain from other impurities.

[0003] However, current air supply mechanisms can generally only blow air into the cleaning screen to separate the grain from the light impurities on its surface. They cannot effectively separate the grain from the light impurities on its surface, resulting in the screened grain being mixed with some light impurities, which reduces the cleanliness of the grain. Utility Model Content

[0004] The main purpose of this invention is to provide a dual-channel Sacron air supply mechanism for cleaning screens, which can effectively solve the problem that current air supply mechanisms cannot effectively separate dust from grains.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dual-duct Sacron air supply mechanism for cleaning screens includes a support frame, a feed box mounted on the support frame, several flow equalization plates mounted inside the feed box, a first air guide groove mounted on one side of the feed box, an air inlet on the lower side of one of the flow equalization plates, one end of the first air guide groove communicating with the air inlet, a third air guide groove mounted on the support frame, a second air guide groove mounted on the upper end of the third air guide groove, the other end of the first air guide groove connected to the second air guide groove, both ends of the second air guide groove connected to a cylindrical part of a Sacron dust collector, and a conical part of a Sacron dust collector mounted on the lower end of the cylindrical part of the Sacron dust collector.

[0007] The vibrating screen body is mounted on the support frame. A vibrating motor mounting base is mounted on one side of the vibrating screen body. A vibrating motor is mounted on the vibrating motor mounting base. A grain outlet is mounted on one side of the vibrating screen body. The grain outlet extends into the third air guide groove. A clean grain outlet is provided at the bottom of the third air guide groove. A grain outlet notch is provided on one side of the grain outlet.

[0008] Preferably, the upper end of the third air guide groove is provided with two openings, and the upper end of the cylindrical part of the Sacron dust collector is provided with a first fan, and a first drive motor is installed on the first fan.

[0009] Preferably, the lower end of the conical section of the Sacron dust collector is fitted with an ash discharge auger, one end of which is fitted with a second drive motor, and the other end of which is fitted with a one-way cover.

[0010] Preferably, a number of casters are installed on the lower side of the support, a buffer seat is installed on the support, and the vibrating screen body is installed on the buffer seat.

[0011] Preferably, a flow divider is installed in the first air guide groove, a first regulating valve is installed on the first air guide groove, and a second regulating valve is installed in the third air guide groove.

[0012] Preferably, a first observation window is installed on the first air guide groove, and a second observation window and a third observation window are installed on the third air guide groove.

[0013] Preferably, a second fan is mounted on the support frame, a third drive motor is mounted on one side of the second fan, and a guide plate is provided at one end of the second fan, with the guide plate facing the grain outlet.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The air supply mechanism of this utility model performs a first air separation and dust removal on the grain fed into the vibrating screen using a Sacron dust collector. It can also perform a second air separation and dust removal on the grain screened by the vibrating screen, effectively reducing the dust content in the grain and improving its cleanliness. Before the first air separation and dust removal, the grain falls onto the flow equalization plate. During this process, the grain separates from the dust on its surface. The air inlet below the flow equalization plate can absorb the light dust. The gas containing dust enters the second air guide groove through the first air guide groove and then enters the Sacron dust collector for the first dust removal operation. At the second air separation position and the grain outlet of the vibrating screen, the light impurities generated during the vibrating screening process can be recovered, effectively improving the cleanliness of the grain.

[0016] 2. The grain outlet of this utility model has an opening that can effectively increase the horizontal projection area of ​​the waterfall formed by the falling grain, making it easier to separate the grain from the dust. A second fan is installed below the grain outlet. The air blown by the second fan is blown towards the grain outlet through the air guide plate. On the one hand, the air can blow the light impurities mixed in with the grain to the bottom of the third air guide groove. On the other hand, it can increase the horizontal projection area of ​​the waterfall formed by the falling grain, making it easier to separate the grain from the dust, and further improving the cleanliness of the grain.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1-10 As shown, the device includes a support 201, on which a feed box 101 is mounted. Several flow equalization plates 116 are mounted inside the feed box 101. A first air guide groove 103 is mounted on one side of the feed box 101. An air inlet 120 is opened on the lower side of one of the flow equalization plates 116. One end of the first air guide groove 103 is connected to the air inlet 120. A third air guide groove 107 is mounted on the support 201. A second air guide groove 106 is mounted on the upper end of the third air guide groove 107. The other end of the first air guide groove 103 is connected to the second air guide groove 106. Both ends of the second air guide groove 106 are connected to a cylindrical part 109 of a Saclon dust collector. A conical part 110 of a Saclon dust collector is mounted on the lower end of the cylindrical part 109. In this embodiment, the conical part 110 of the Saclon dust collector is a cone inlaid with transparent glass.

[0031] In this embodiment, the grain entering the feed box 101 can be evenly distributed by the flow equalization plate 116 to prevent the grain from piling up, so that the grain can enter the vibrating screen more evenly, thereby effectively preventing the grain from piling up in the vibrating screen and further improving the screening speed of the vibrating screen. When in use, the grain will hit the flow equalization plate 116 when it passes through it. During this process, the grain will separate from the dust on its surface. The air inlet 120 below the flow equalization plate 116 can suck up the light dust. The gas with dust will enter the second air guide channel 106 through the first air guide channel 103 and then enter the Sacron dust collector for the first dust removal operation.

[0032] A vibrating screen body 204 is mounted on the support frame 201. A vibrating motor mounting base 205 is mounted on one side of the vibrating screen body 204. A vibrating motor 206 is mounted on the vibrating motor mounting base 205. A grain outlet 118 is mounted on one side of the vibrating screen body 204. The grain outlet 118 extends into the third air guide channel 107. A clean grain outlet 119 is provided at the bottom of the third air guide channel 107. A grain outlet notch 122 is provided on one side of the grain outlet 118.

[0033] In this embodiment, when the grain is vibrated and screened by the vibrating screen, the grain will be further separated from the impurities on its surface. When the grain flows out from the grain outlet 118, the Sacron dust collector will use negative pressure to suck up the light impurities in the grain at the lower end of the third air guide groove 107, so that the gas with light impurities enters the Sacron dust collector for the second dust removal operation.

[0034] Specifically, the vibrating motor 206 can vibrate the grain inside the vibrating screen, as shown in the reference. Figure 9 and Figure 10 When there is no grain outlet opening 122 at grain outlet 118 (refer to...) Figure 9 The horizontal projection area of ​​the waterfall formed by the falling grain is small, and the grain cannot be well separated from the debris or other small particles separated by vibration. When a grain outlet opening 122 is provided at the grain outlet 118 (refer to...), Figure 10 The waterfall formed by the falling grain has a large horizontal projection area, which makes it difficult to separate the grain from the debris or other small particles separated by vibration. This can effectively facilitate the next step of the second dust removal operation, effectively reduce the impurities in the grain screened by vibration, and make the screened grain cleaner.

[0035] The upper end of the third air guide groove 107 has two openings. The upper end of the cylindrical part 109 of the Saclon dust collector is provided with a first fan 114. A first drive motor 115 is installed on the first fan 114. The lower end of the conical part 110 of the Saclon dust collector is provided with a dust discharge auger 111. A second drive motor 112 is installed at one end of the dust discharge auger 111, and a one-way cover 113 is installed at the other end of the dust discharge auger 111.

[0036] In this embodiment, the one-way cover 113 can effectively prevent debris from entering the ash discharge auger 111, making it easier for the ash discharge auger 111 to work, and can also further improve the suction power of the Sacron dust collector during operation.

[0037] Several casters 202 are installed on the lower side of the support 201. A buffer seat 203 is installed on the support 201. The vibrating screen body 204 is installed on the buffer seat 203. A flow divider 105 is installed in the first air guide channel 103. A first regulating valve 102 is installed in the first air guide channel 103. A second regulating valve 121 is installed in the third air guide channel 107. A first observation window 104 is installed in the first air guide channel 103. A second observation window 108 and a third observation window 117 are installed in the third air guide channel 107.

[0038] A second fan 207 is installed on the support frame 201. A third drive motor 209 is installed on one side of the second fan 207. A guide plate 208 is provided at one end of the second fan 207, and the guide plate 208 is set towards the grain outlet 118.

[0039] Specifically, a second fan 207 is installed on the lower side of the bracket 201. The second fan 207 is a blower, and the air blown by the second fan 207 is blown towards the grain outlet 118 through the air guide plate 208 (see reference). Figure 7 On the one hand, it can blow air to blow the light impurities mixed in the grain towards the bottom of the third air guide groove 107. On the other hand, it can increase the horizontal projection area of ​​the waterfall formed by the falling grain, making it easier to separate the grain from the dust.

[0040] Reference Figure 4 The black arrows in the diagram indicate the direction of gas flow. Gas containing light impurities is divided into two parts by the diverter plate 105, and each part is then introduced into its corresponding Sacron dust collector. (Refer to...) Figure 7 In the diagram, the black arrows represent the grain to be screened, the white arrows represent the gas containing light dust, the gray arrows represent the direction of airflow from the second fan 207, and the hollow arrows represent the direction of the clean grain falling.

[0041] It should be noted that this utility model provides a dual-channel Sacron air supply mechanism for cleaning screens, which can be installed on commonly used vibrating screens. The air supply mechanism performs a first air separation and dust removal on the grain fed into the vibrating screen through the Sacron dust collector, and can also perform a second air separation and dust removal on the grain screened by the vibrating screen, effectively reducing the dust content in the grain. Before the first air separation and dust removal, the grain will first fall on the flow equalization plate 116. During this process, the grain is separated from the dust on its surface. The air inlet 120 below the flow equalization plate 116 can absorb light dust. The gas containing dust enters the second air guide channel 106 through the first air guide channel 103, and then enters the Sacron dust collector for the first dust removal operation. At the second air separation position and the grain outlet 118 of the vibrating screen, light impurities generated during the vibrating screening process can be recovered, effectively improving the cleanliness of the grain. Moreover, this application is a dual-channel type, which can effectively improve the suction power and working efficiency of the Sacron dust collector.
