DETAILED DESCRIPTION
[0027] The following will be combined with 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 of 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] like Figure 1-Figure 5 As shown, a quartz sand filter device for wastewater treatment includes a filter box 1, and a box cover 102 is hinged at the box opening of the filter box 1 through a hinge 101;
[0029] A first filter plate 2 is arranged in the filter box 1, a through groove 3 is formed on one side of the inner wall of the filter box 1, a connecting plate 301 is slidably arranged in the through groove 3, and one side of the connecting plate 301 is fixedly connected to the first filter plate 2;
[0030] A second filter plate 4 is fixedly installed inside the filter box 1 and below the first filter plate 2, and the second filter plate 4 is tilted;
[0031] A material trough 5 is formed through the inner wall surface of the filter box 1 .
[0032] The staff opens the box cover 102, and then pours the waste water into the filter box 1 through the opening of the filter box 1. Then, under the filtering action of the quartz sand, the first filter plate 2 and the second filter plate 4, various impurities in the waste water are filtered, thereby purifying the waste water. After the quartz sand is used for a long time, the staff pulls the connecting plate 301 to drive the first filter plate 2 to move along the through groove 3, and finally the first filter plate 2 moves to the outside of the filter box 1, so that the quartz sand accumulated on the upper surface of the filter box 1 falls to the inclined surface of the second filter plate 4, and then the quartz sand moves along the inclined surface of the second filter plate 4 and finally moves to the outside of the filter box 1 through the material trough 5. There is no need for the staff to reach into the filter box 1 to take out the quartz sand. The process of taking out the quartz sand is simple and avoids the staff from inhaling harmful gases.
[0033] In another embodiment of the present invention, a movable groove 501 is formed through one side of the inner wall of the material trough 5 , and a baffle 502 is slidably disposed in the movable groove 501 .
[0034] A right angle bracket 503 is fixedly mounted on one side of the connecting plate 301 close to the baffle plate 502 , and the lower surface of the right angle bracket 503 is fixedly connected to the baffle plate 502 .
[0035] By setting the baffle 502, the material trough 5 can be covered to prevent wastewater from leaking to the outside of the filter box 1 through the material trough 5 during the filtering work. By setting the right-angle frame 503, when the staff moves the connecting plate 301 and moves the first filter plate 2 to the outside of the filter box 1, the baffle 502 moves to the outside of the material trough 5 to facilitate the discharge of quartz sand.
[0036] In another embodiment of the utility model, a support plate 6 is fixedly installed on one side of the filter box 1 close to the connecting plate 301, and a slide groove 601 is provided on the upper surface of the support plate 6. A slider 602 is slidably provided in the slide groove 601, and the upper surface of the slider 602 is fixedly connected to the connecting plate 301;
[0037] A screw rod 603 is rotatably installed between the two sides of the inner wall of the slide groove 601, and the slider 602 is threadedly arranged on one side of the rod body of the screw rod 603;
[0038] A motor 604 is fixedly mounted on one side of the support plate 6 , and one end of the screw rod 603 passes through the support plate 6 and is fixedly connected to the output shaft end of the motor 604 .
[0039] The staff starts the motor 604 so that its output shaft end drives the screw rod 603 to rotate, and the rotating screw rod 603 drives the slider 602, the connecting plate 301 and the first filter plate 2 to move by screwing in the thread.
[0040] In another embodiment of the utility model, two conducting rods 7 are fixedly installed on one side of the filter box 1, and one end of the two conducting rods 7 passes through the filter box 1 and is fixedly connected to the second filter plate 4;
[0041] A conducting plate 701 is fixedly mounted on the other ends of the two conducting rods 7 .
[0042] A vertical plate 8 is fixedly installed on one side of the filter box 1 close to the conduction plate 701. A connecting groove 801 is opened on one side of the vertical plate 8. A connecting block 802 is slidably arranged in the connecting groove 801. A lifting plate 803 is fixedly installed on one side of the connecting block 802. Beating balls 804 are fixedly installed on both sides of the lower surface of the lifting plate 803 through pillars.
[0043] The staff moves the lifting plate 803 back and forth, causing the hitting ball 804 to move back and forth, so that the hitting ball 804 hits the conductive plate 701, causing the conductive plate 701 to transmit the vibration to the second filter plate 4 through the conductive rod 7, thereby causing the quartz sand sticking to the surface of the second filter plate 4 to fall off, eliminating the need for manual cleaning by the staff, thereby reducing the workload of the staff.
[0044] In another embodiment of the utility model, connecting rods 805 are fixedly installed on both sides of the inner wall of the connecting groove 801, and the connecting block 802 is slidably arranged on one side of the connecting rod 805;
[0045] A spring 806 is sleeved on the other side of the connecting rod 805 .
[0046] By providing the spring 806, under the elastic force generated by the spring 806 being compressed and then restored, the force with which the striking ball 804 strikes the conductive plate 701 is greatly increased, so that the second filter plate 4 vibrates more strongly, causing the quartz sand on its surface to fall off more fully.
[0047] The working principle of the quartz sand filter device for wastewater treatment:
[0048] When in use, the staff opens the box cover 102, and then the staff pours the waste water into the filter box 1 through the opening of the filter box 1. Then, under the filtering action of the quartz sand, the first filter plate 2 and the second filter plate 4, various impurities in the waste water are filtered, thereby purifying the waste water. After the quartz sand is used for a long time, the staff pulls the connecting plate 301 to drive the first filter plate 2 to move along the through groove 3, and finally the first filter plate 2 moves to the outside of the filter box 1, so that the quartz sand accumulated on the upper surface of the filter box 1 falls to the inclined surface of the second filter plate 4, and then the quartz sand moves along the inclined surface of the second filter plate 4, and finally moves to the outside of the filter box 1 through the material trough 5. There is no need for the staff to reach into the filter box 1 to take out the quartz sand. The process of taking out the quartz sand is simple and avoids the staff from inhaling harmful gases.
[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
