[0027] 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 technicians in this field without creative work are within the scope of protection of the utility model.
[0028] As the instruction manual Figure 1 , 2 As shown in Figure 4, a dust removal device for grain and oil production includes a housing 1, a filter element 2, an air jet device 3, and an ash collecting device. The filter element 2 is fixedly arranged inside the housing 1. The filter element 2 includes a fixed frame 2.1 fixedly arranged inside the housing 1, a plurality of cloth bags 2.2 movably arranged on the fixed frame 2.1, and a plurality of partition plates 2.3 fixedly arranged at the bottom of the fixed frame 2.1, and the plurality of partition plates 2.3 separate the plurality of cloth bags 2.2. The air jet device 3 is fixedly arranged above the filter element 2, and the air jet device 3 passes through the filter element 2. The ash collecting device is fixedly arranged at the bottom of the housing 1, and the dust is collected by the ash collecting device for unified treatment.
[0029] As the instruction manual Figure 1 , 2As shown in Figures 4 and 5, an air inlet 5 is fixedly provided on one side of the housing 1, a first baffle 6 is provided between the air inlet 5 and the filter element 2, and the first baffle 6 is fixedly connected to the inner side of the housing 1. A shaking assembly 4 is provided inside the housing 1, and the shaking assembly 4 shakes the filter element 2. The shaking assembly 4 includes a plurality of shaking shafts 4.1 located at the bottom of the filter element 2, a pair of brackets 4.2 fixedly provided at both ends of the plurality of shaking shafts 4.1, a rotating shaft 1 fixedly connected to one of the brackets 4.2, a driven wheel 4.3 fixedly provided at one end of the rotating shaft 1, a driving wheel 4.4 provided above the driven wheel 4.3, and a first motor 4.5 driving the driving wheel 4.4 to rotate. The driving wheel 4.4 is connected to the driven wheel 4.3 through a transmission assembly 8, and the transmission assembly 8 drives the driven wheel 4.3 to rotate back and forth.
[0030] As the instruction manual Figure 1 , 2 As shown in Figures 3 and 5, the bracket 4.2 away from the rotating shaft 1 is rotatably connected to the housing 1 through the rotating shaft 3, and the rotating shaft 3 is connected to the housing 1 through the bearing 2. One end of the output shaft of the first motor 4.5 is fixedly connected to the rotating shaft 2, and one end of the rotating shaft 2 is fixedly connected to the driving wheel 4.4, and the driven wheel 4.3 is connected to the bracket 4.2. The first motor 4.5 drives the driving wheel 4.4 to rotate, and the driving wheel 4.4 drives the driven wheel 4.3 to rotate through the transmission assembly 8, thereby realizing the movement of the bracket 4.2 driven by the first motor 4.5.
[0031] As the instruction manual Figure 1 , 5 As shown, the transmission assembly 8 includes a first rocker 8.1 rotationally connected to the driving wheel 4.4 through a connecting shaft 1, and a second rocker 8.2 rotationally connected to the first rocker 8.1. The first rocker 8.1 and the second rocker 8.2 are rotationally connected through a connecting shaft 2, a pair of sliders are fixedly provided at both ends of the connecting shaft 2, and the first baffle 6 and the second baffle 7 are both provided with limiting grooves for sliding of the sliders. The second rocker 8.2 is rotationally connected to the driven wheel 4.3 through a connecting shaft 3. Since the diameter of the driving wheel 4.4 is smaller than that of the driven wheel 4.3, the driving wheel 4.4 does not cause the driven wheel 4.3 to perform a complete circular motion through the transmission assembly 8, and only reciprocating rotation at a certain angle will be generated.
[0032] As the instruction manual Figure 1 , 2As shown, a second baffle 7 is fixedly arranged at the bottom of the first motor 4.5, one side of the second baffle 7 is fixedly connected to the inner side of the housing 1, and the other side is fixedly connected to the first baffle 6, and the driven wheel 4.3 is rotatably arranged between the first baffle 6 and the second baffle 7. The partial structure of the shaking assembly 4 is located between the first baffle 6 and the second baffle 7, which will not cause significant interference to the dust removal process, and the rotating shaft 1 rotates through the first baffle 6 and is connected to the first baffle 6 through the bearing 1. The length of the partition plate 2.3 is less than the length of the cloth bag 2.2, and the partition plate 2.3 will not hinder the movement of the shaking shaft 4.1.
[0033] The working principle of this utility model:
[0034] The impurity gas enters the dust collector from the air inlet 5, and the impurity gas will hit the second baffle 7. At this time, the larger dust will fall into the dust collecting device below with the second baffle 7. Then the impurity gas will pass through the filter element 2, and the dust in the impurity gas will be adsorbed on the bag 2.2. Then the gas with impurities removed will be discharged from the air outlet above the dust collector.
[0035] After a period of use, a large amount of dust is adsorbed on the cloth bag 2.2, and the jet device 3 is started to spray gas into the cloth bag 2.2 to blow off the dust adsorbed on the surface of the cloth bag 2.2. Since any cloth bag 2.2 is separated by a partition plate 2.3, part of the dust will be blown onto the partition plate 2.3 and then fall along the partition plate 2.3.
[0036] The first motor 4.5 is started, and the first motor 4.5 drives the rotating shaft 2 to rotate through the output shaft. Since the driving wheel 4.4 is fixedly connected to one end of the rotating shaft 2, the driving wheel 4.4 is driven to rotate. When the driving wheel 4.4 rotates, it will drive the first rocker 8.1 to move through the connecting shaft 1. Since the other end of the first rocker 8.1 is rotationally connected to the connecting shaft 2, and the connecting shaft 2 slides between the first baffle 6 and the second baffle 7 through the sliders at both ends, the first rocker 8.1 will drive the connecting shaft 2 to move up and down. Since the second rocker 8.2 is also rotationally connected to the connecting shaft 2, it will drive the second rocker 8.2 to move. At this time, the other side of the second rocker 8.2 is rotationally connected to the driven wheel 4.3 through the connecting shaft 3, which will cause the driven wheel 4.3 to rotate.
[0037] Since the diameter of the driving wheel 4.4 is smaller than that of the driven wheel 4.3, when the first rocker 8.1 makes the connecting shaft 2 reciprocate with the driving wheel 4.4, the distance moved by the connecting shaft 2 is not enough to drive the driven wheel 4.3 to make a complete circular motion through the second rocker 8.2, and the driven wheel 4.3 can only reciprocate at a certain angle. Since the driven wheel 4.3 is connected to the bracket 4.2 through the rotating shaft 1, and the bracket 4.2 is provided with a plurality of shaking shafts 4.1, the bracket 4.2 will drive the shaking shafts 4.1 to reciprocate, and since the shaking shafts 4.1 are provided at the bottom of the filter element 2, the shaking shafts 4.1 will hit the cloth bag 2.2, so that the dust adsorbed at the bottom of the cloth bag 2.2 will fall off.
[0038] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
