Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction in organic fertilizer production, in particular to a dust reduction device for organic fertilizer production. Background Art

[0002] In the production of organic fertilizers, raw materials such as animal and plant waste and agricultural waste need to be crushed and ground. During this process, the use of equipment such as crushers and grinders generates a large amount of dust, so dust suppression devices are required to absorb the dust generated by the crushers.

[0003] After searching, the Chinese patent "A straw crushing and dust reduction device based on organic fertilizer production" authorization announcement number "CN220556939U" uses a diversion pipe, fan, air duct, filter and knocking hammer to draw the dust inside the crusher into the dust removal box, and then filter it out through the filter. The filter can be knocked on the filter by picking up the knocking hammer to achieve simple cleaning of the filter and avoid serious blockage.

[0004] When cleaning the above-mentioned filter, it is necessary to manually pick up a hammer to knock it. If the knocking force is too strong, it is easy to cause damage to the filter, thereby affecting the dust reduction effect.

[0005] Therefore, a dust suppression device for organic fertilizer production is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4As shown, a dust reduction device for organic fertilizer production includes: a base frame 1, a stirring frame 2 is fixedly connected to the top of the base frame 1, a feeding hopper 3 is fixedly connected to one side of the stirring frame 2, a curtain 4 is provided on the inner side of the feeding hopper 3, a dust collection box 5 is fixedly connected to the top of the base frame 1, a vacuum pump 7 is connected to one side of the dust collection box 5, and a dust collection pipe 6 is connected to one side of the dust collection box 5; a cleaning mechanism 8 is provided on the surface of the dust collection box 5; wherein the cleaning mechanism 8 includes a filter frame 81 slidably connected to the inner wall of the dust collection box 5, and the filter frame 81 has a A filter screen 82 is fixedly connected to the inside, a material receiving frame 84 is provided on one side of the stirring frame 2, a rubber sleeve 85 is fixedly connected to one side of the material receiving frame 84, a driven block 86 is fixedly connected to one side of the filter frame 81, a movable frame 813 is slidably connected to the inner wall of the dust collection box 5, and a number of rubber pads 815 are fixedly connected to the inner wall of the dust collection box 5. The filter screen 82 is wavy as a whole, one side of the movable frame 813 is curved in an arc shape, the surface of the driven block 86 is half cylindrical, and the front and rear ends of the base frame 1 are fixedly connected with magnetic blocks 83.

[0025] Crushing rollers are rotatably connected to both sides of the inner wall of the mixing frame 2, one end of the crushing roller is fixedly connected to a gear, and the two gears are meshed. The front end of the mixing frame 2 is fixedly connected to a second servo motor, and the output shaft of the second servo motor is fixedly connected to one end of one of the gears. An exhaust hole is provided at one end of the vacuum pump 7, and the material receiving frame 84 is an iron component.

[0026] When the straw needs to be processed, the receiving frame 84 is pushed to be located between the two magnetic blocks 83, so that the rubber sleeve 85 is in contact with the discharge port of the mixing frame 2. Because the receiving frame 84 is an iron component, the magnetic block 83 is adsorbed and positioned to receive the frame 84. The power switches on the mixing frame 2 and the dust box 5 are manually turned on. The output shaft of the second servo motor rotates through the gear to drive the crushing roller to rotate. The straw enters the rotating crushing roller through the feed hopper 3 to crush the straw. The vacuum pump 7 extracts the air in the dust box 5 to form a negative pressure therein. The dust pipe 6 extracts the overflowed dust and the air output. The dust is sent to the dust collection box 5. Because the filter screen 82 is wavy, the filter screen 82 effectively disperses the force, so that the force on the entire filter screen 82 is uniform, thereby strengthening the overall strength of the filter screen 82. The filter screen 82 with an uneven surface intercepts more dust. The movable frame 813 moves and contacts the driven block 86, pushing the driven block 86 and the filter frame 81 to move horizontally and squeeze the spring 88. The movable frame 813 moves away from the driven block 86. The elastic force of the spring 88 pushes the filter frame 81 toward the direction close to the nozzle 811, causing the filter frame 81 to hit the rubber pad 815, so that the dust is separated from the filter screen 82.

[0027] like Figure 2-3As shown, the inner top wall and the inner bottom wall of the dust box 5 are fixedly connected with a protective tube 87, one end of the filter frame 81 is slidably connected to the inner wall of the protective tube 87, the protective tube 87 and the opposite end of the filter frame 81 are fixedly connected with a spring 88, the inner side of the movable frame 813 is fixedly connected with a nozzle 810, the surface of the nozzle 810 is connected with nozzles 811 distributed in an equal row, one end of the vacuum pump 7 is connected with a corrugated hose 812, the bottom end of the corrugated hose 812 is connected to the nozzle 810, and the nozzle 811 is connected to the inner side of the movable frame 813. The overall shape is half a sphere and a number of air outlets are provided on the surface of the nozzle 811. The top of the dust box 5 is fixedly connected to the first servo motor 814, and the top of the dust box 5 is rotatably connected to the reciprocating screw 89. The output shaft of the first servo motor 814 is fixedly connected to the bottom end of the reciprocating screw 89. The inner wall of the movable frame 813 is arranged on the surface of the reciprocating screw 89. The top of the dust box 5 is fixedly connected to the limit rod, and the inner wall of the movable frame 813 is slidably connected to the surface of the limit rod.

[0028] The reciprocating screw 89 is a screw that can make the movable frame 813 reciprocate without changing the direction of rotation of the main shaft. The reciprocating screw 89 is in the form of two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the screw, the side of the spiral groove pushes the movable frame 813 placed in the spiral groove to perform axial reciprocating motion.

[0029] After the first servo motor 814 is energized, its output shaft rotates to drive the reciprocating screw 89 to rotate, and the reciprocating screw 89 rotates to drive the movable frame 813 to rise and fall back and forth in the dust box 5. The reciprocating rise and fall of the movable frame 813 drives the nozzle 810 and the nozzle 811 to rise and fall back and forth, and the filtered air is transported to the nozzle 810 and the nozzle 811 through the corrugated hose 812. Because the nozzle 811 is in the shape of half a sphere and there are several air outlets on the surface of the nozzle 811, the nozzle 811 sprays a large range of wind to flush the surface of the filter 82, so that the dust is separated from the filter 82.

[0030] When the utility model is in use, the material receiving frame 84 is pushed to be located between the two magnetic blocks 83, so that the rubber sleeve 85 contacts the surface of the discharge port of the stirring frame 2. Because the material receiving frame 84 is an iron component, the magnetic block 83 adsorbs and positions the material receiving frame 84. The power switch on the stirring frame 2 and the dust box 5 is manually turned on. The output shaft of the second servo motor rotates through the gear to drive the crushing roller to rotate. The straw enters the rotating crushing roller through the feed hopper 3, so that the straw is crushed. The vacuum pump 7 extracts the air in the dust box 5 to form a negative pressure therein. The dust suction pipe 6 extracts the overflowed dust and air and transports it to the dust box 5. The filter screen 82 with an uneven surface intercepts more dust. The filtered air is transported to the nozzle 810 and the nozzle 811 through the corrugated hose 812. A portion of the air is discharged through the exhaust hole on the vacuum pump 7, and the movable frame 813 is driven to rise and fall back and forth by the first servo motor 814 and the reciprocating screw 89. The reciprocating rise and fall of the movable frame 813 drives the nozzle 810 and the nozzle 811 to rise and fall back and forth. The movable frame 813 moves and contacts the driven block 86, pushing the driven block 86 and the filter frame 81 to move laterally and squeeze the spring 88. The movable frame 813 moves away from the driven block 86. The elastic force of the spring 88 pushes the filter frame 81 toward the direction close to the nozzle 811, causing the filter frame 81 to hit the rubber pad 815. Because the nozzle 811 is in the shape of half a sphere and a plurality of air outlets are provided on the surface of the nozzle 811, the nozzle 811 sprays a large range of wind to flush the surface of the filter 82, so that the dust is separated from the filter 82.

[0031] It should be noted that the first servo motor 814, the second servo motor, the vacuum pump 7 and the magnetic block 83 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the first servo motor 814, the second servo motor and the vacuum pump 7 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
