DETAILED DESCRIPTION
[0023] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0024] like Figure 1 and Figure 2 As shown, the utility model is an auxiliary dust removal device for producing fine machine-made sand, comprising a vibrating screen 1 and a vibration drive assembly. A fixing frame is fixedly installed at the bottom end of the vibrating screen 1, and a vibration drive assembly is arranged on the inner side of the fixing frame. Two rotating grooves 18 are arranged on the two side surfaces of the vibrating screen 1, and a rotating rod 11 is fixedly installed inside the rotating groove 18. A rotating pressing plate 3 is rotatably installed on the outer surface of the rotating rod 11. The rotating pressing plate 3 is movably inserted into the rotating groove 18, and a baffle 8 is fixedly installed at the end of the rotating pressing plate 3. Three dust removal chambers 13 are arranged inside the vibrating screen 1, and the uppermost and middle dust removal chambers 13 are arranged inside the vibrating screen 1. Three support rods 15 are fixedly installed at the bottom ends of the inner cavities of the two dust removal chambers 13, a first filter screen 4 is slidably installed inside the dust removal chamber 13 located at the top, and a second filter screen 12 is slidably installed inside the dust removal chamber 13 located in the middle. By rotating the pressing plate 3 and the baffle 8, when the device is in use, the first filter screen 4 and the second filter screen 12 can be limited by rotating the pressing plate 3 and the baffle 8, so that the first filter screen 4 and the second filter screen 12 will not slide out of the slot 17 directly due to the vibration of the vibrating screen 1, thereby avoiding the first filter screen 4 and the second filter screen 12 from falling off due to vibration.
[0025] As the preferred technical solution of this embodiment, Figure 3 and Figure 4 As shown, the top surface of the rotating groove 18 is provided with a spring groove 9, the top of the movable plate 7 is slidably inserted into the spring groove 9, and a plurality of compression springs 10 are movably installed between the top of the movable plate 7 and the inside of the spring groove 9. A feed inclined plate 5 is fixedly installed on one side of the vibrating screen 1, and a conveyor belt 6 is arranged above the feed inclined plate 5. A collection box 2 is fixedly installed on the other side of the vibrating screen 1, and three collection cavities 14 are arranged inside the collection box 2. The collection cavities 14 correspond to the outlet positions of the three dust removal cavities 13 respectively. Through the cooperation of the movable plate 7 and the compression spring 10, the device can be used. By moving the rotating pressure plate 3 upward along the surface of the rotating rod 11, the space between the rotating pressure plate 3 and the support rod 15 is increased, and filter screens of different thicknesses can be installed under the rotating pressure plate 3, so that the device can install filter screens of different sizes, and when the rotating pressure plate 3 moves upward along the rotating rod 11, it will squeeze the movable plate 7, causing the movable plate 7 to retract into the spring groove 9. When the rotating pressure plate 3 presses the replaced filter screen, the movable plate 7 will rebound due to the elastic potential energy of the compression spring 10 to seal the rotating groove 18, thereby preventing the machine-made sand from leaking through the rotating groove 18.
[0026] In this embodiment, the baffle 8 is movably inserted into the interior of the material collection cavity 14 , a movable support frame is fixedly installed at the bottom end of the material collection box 2 , and the filter hole size on the surface of the second filter screen 12 is smaller than the filter hole size on the surface of the first filter screen 4 .
[0027] As the preferred technical solution of this embodiment, Figure 5 As shown, the bottom ends of the first filter 4 and the second filter 12 are both fitted with the top surface of the support rod 15, and the bottom surface of the rotating pressure plate 3 is fitted with the two side positions of the top surface of the first filter 4 and the second filter 12. The two side surfaces of the bottom ends of the first filter 4 and the second filter 12 are fixedly installed with fixed rods 16, and the inside of the dust removal chamber 13 is close to the fixed rod 16. The fixed rod 16 is slidably inserted into the inside of the slot 17. Through the cooperation of the fixed rod 16 and the slot 17, the first filter 4 and the second filter 12 can be disassembled by sliding the first filter 4 and the second filter 12 out of the slot 17 through the fixed rod 16 when the device is in use, so that the first filter 4 and the second filter 12 can be easily replaced and cleaned, and the filter screens with different sizes of filter holes can be replaced.
[0028] Working principle: first move out the collecting box 2, then rotate the rotating pressure plate 3 outward, so that the rotating pressure plate 3 rotates outward along the surface of the rotating rod 11 to open the position of the first filter 4 and the second filter 12, and at the same time, according to the size of the filter to be installed, the rotating pressure plate 3 can be lifted upward along the surface of the rotating rod 11, so that the space between the rotating pressure plate 3 and the support rod 15 is adapted to the thickness of the installed filter, and then the first filter 4 and the second filter 12 can be replaced. After the replacement is completed, the rotating pressure plate 3 is rotated back to the inside of the rotating groove 18. At this time, the movable plate 7 will be ejected by the elastic potential energy of the compression spring 10 and squeeze the rotating pressure plate 3, so that the rotating pressure plate 3 presses the first filter 4 and the second filter 12 to prevent the first filter 4 and the second filter 12 from slipping, and the first filter 4 and 2 are limited by the baffle 8 to further improve the first filter 4 and the second filter 12. The stability of the machine-made sand is then transported into the interior of the feed inclined plate 5 through the conveyor belt 6. The machine-made sand falls into the dust removal chamber 13 of the top layer through the feed inclined plate 5. At this time, the vibrating screen 1 is started to make the vibrating screen 1 start to vibrate through the vibration drive component. The machine-made sand will pass through the first filter screen 4 to filter the fine particles of machine-made sand and stone powder into the middle dust removal chamber 13. Then the stone powder will pass through the second filter screen 12 to filter into the dust removal chamber 13 of the bottom layer. Then the large particles of machine-made sand, small particles of machine-made sand, and stone powder will pass through the dust removal chamber 13 into the three aggregate chambers 14 in turn, thereby completing the separation of the machine-made sand. Then the fine particles of machine-made sand are sent to the dust collector for dust removal, thereby avoiding the situation in which all raw materials enter the dust collector in the conventional dust removal method, which will be affected by large particles, resulting in low dust removal efficiency, thereby improving the dust removal efficiency.
[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
