[0001] The invention belongs to the technical field of filtering and discharging slag, and in particular is a slag discharging device for filtering equipment. Background Art

[0002] In order to improve the utilization of water resources, the tap water plant generally recycles the sewage in the city and performs impurity filtration, so as to further filter the sewage by chemical means in the future. In the existing technical scheme, filtering equipment is generally used for filtration. After the filter plate used in the equipment works for a long time, impurities attached to it, such as sand or sludge and other waste materials, will reduce the filtration quality and filtration speed.

The limiting plates 61 are provided with slots on both sides close to the flushing assembly 2. The two limiting plates 61 are fixedly connected to form a limiter. A plurality of tooth plates 63 are equidistantly installed on the opposite surfaces of the two limiting plates 61. The tooth plates 63 on two adjacent limiting plates 61 are staggered. The clamping components 3 are installed on both sides of the slag box 1, and the clamping components 3 are used to push the limiting components 6 to press and fix the filter plate 8; The slag discharge assembly 7 includes two threaded rods 71 ​​rotatably mounted on both sides of the slag discharge box 1, and a sleeve plate 72 is respectively threadedly sleeved on the two threaded rods 71, and a main shaft 73 is sleeved on the two sleeve plates 72. Two brushes 74 are symmetrically arranged on the outer periphery of the main shaft 73, and two gears 75 are symmetrically arranged on the outer periphery of the main shaft 73. A follower ring 78 is sleeved on the outer periphery of the threaded rod 71, and the follower ring 78 is connected to the guide wheel 70 through a chain 77. The top of the guide wheel 70 is eccentrically connected to a guide rod 701, and the guide rod 701 is movably engaged with the main shaft 73. A sealing plate 76 is rotatably mounted on the outer periphery of the follower ring 78, and the side of the sealing plate 76 is connected to a limiting cylinder 79 movably sleeved inside the main shaft 73, and the guide wheel 70 is rotatably mounted on the top of the limiting cylinder 79; A motor 4 is installed at the bottom of the slag box 1, and the output shaft of the motor 4 is transmission-connected with an internal gear 41; A power assembly 5 is respectively arranged at both ends of the bottom of the slag box 1, and the output shaft of the motor 4 drives each threaded rod 71 to rotate through the internal gear 41 and the power assembly 5.

[0020] The limiting assembly 6 includes two limiting plates 61 slidably installed inside the slag box 1. The limiting plates 61 are provided with slots on both sides close to the flushing assembly 2. The two limiting plates 61 are fixedly connected to form a limiter. A plurality of tooth plates 63 are equidistantly installed on the opposite surfaces of the two limiting plates 61. The tooth plates 63 on two adjacent limiting plates 61 are staggered, and the positions of every two tooth plates 63 are staggered. The limiting assembly 6 also includes limiting grooves 62 respectively opened on the side of the limiting plate 61 . The connection between the brush 74 and the main shaft 73 movably passes through the limiting groove 62 , and the outer periphery of the brush 74 is closely attached to the side of the filter plate 8 .

[0021] The slag discharge assembly 7 is located between the two limit plates 61 in each limit assembly 6. The two limit plates 61 limit the vertical movement of the sleeve plate 72. The rotation of the threaded rod 71 causes the sleeve plate 72 and the main shaft 73 to descend, and the gear 75 reciprocates according to the several staggered tooth plates 63.

[0022] The above scheme is adopted: the filter plate 8 is placed between every two adjacent limiting components 6, and then the limiting components 6 on both sides are squeezed by two clamping components 3. At this time, the filter plate 8 is squeezed by the two limiting components 6 and finally in a fixed state, and the flushing component 2 is turned on to spray water into the slag box 1; The output shaft of the motor 4 drives the second threaded rod 71 to rotate through the internal gear 41 and the power assembly 5. At this time, the sleeve plate 72 descends, and the second gear 75 meshes with each staggered tooth plate 63 in turn. It can be concluded that during the process of the second gear 75 descending, it will also drive the main shaft 73 to swing back and forth; The threaded rod 71 drives the follower ring 78 to rotate, and the follower ring 78 drives the guide wheel 70 to rotate through the chain 77. However, since the guide wheel 70 is eccentrically connected to the guide rod 701, and the guide wheel 70 is rotatably mounted on the limit cylinder 79, and the limit cylinder 79 is movably sleeved inside the main shaft 73, the rotation of the guide wheel 70 will push the main shaft 73 to move back and forth through the guide rod 701, and the width of the limit groove 62 is sufficient to support the left and right swing of the brush 74, and will not cause excessive contact between the connection between the main shaft 73 and the brush 74 and rub the edge of the limit groove 62, thereby further improving the smoothness of the device operation; At this time, the main shaft 73 and the brush 74 swing in a circular state and also swing left and right, thereby better cleaning the edge of the filter plate 8 and improving the efficiency and quality of slag discharge.

[0023] like Figure 1-Figure 8 As shown, a plurality of vertical grooves are formed at equal angles in the circumferential direction of the outer circumference of the second threaded rod 71 , and the follower ring 78 moves vertically on the outer circumference of the second threaded rod 71 through the vertical grooves.

[0024] The above solution is adopted: the follower ring 78 can only move vertically on the outer periphery of the threaded rod 2 71 through the vertical groove, so that when the threaded rod 2 71 rotates, it will also drive the follower ring 78 to rotate, so that the follower ring 78 drives the guide wheel 70 to rotate through the chain 2 77, and the guide rod 701 can reciprocate to push the main shaft 73 to swing.

[0025] like Figure 1 and Figure 2 As shown, the flushing assembly 2 includes a water storage box 21 installed on both sides of the slag discharge box 1, and water tanks 23 for connecting to the inside of the water storage box 21 are equidistantly provided on both sides of the slag discharge box 1. A water pump 22 is provided on the periphery of the water storage box 21 on one side, and the drainage end of the water pump 22 is connected to the water storage box 21. The inside of the water storage box 21 on the other side is sealed with a plug 24.

[0026] A cover plate for sealing the interior of the water storage box 21 is mounted on the outside of each water storage box 21 through a nut.

[0027] The above scheme is adopted: the water inlet end of the water pump 22 is connected to an external water source, and then the water pump 22 is started, and its water outlet end enters the water storage box 21 on one side, and is sprayed into the slag discharge box 1 through the water tank 23, and finally the water is sprayed onto the filter plate 8 through the notch on the side of the limit plate 61, so as to better remove the slag on the filter plate 8, and the cover plate on the side of the water storage box 21 is connected by a nut, so that the subsequent staff can better clean the inside of the water storage box 21; When the device is not in use, it can be blocked by the plug 24, thereby avoiding the possibility of the water outlet being blocked by foreign matter.

[0028] like Figure 1-Figure 3 As shown, the clamping assembly 3 includes a threaded barrel 31 rotatably mounted on the side of the slag box 1, a handle 32 is fixedly installed on the outer periphery of the threaded barrel 31, a threaded rod 33 is installed on the side of the limiting plate 61 close to one side of the threaded barrel 31, and the threaded rod 33 is threadedly mounted inside the threaded barrel 31.

[0029] The above scheme is adopted: the threaded rod 33 is fixedly installed on the limit plate 61. When the staff rotates the threaded barrel 31 through the handle 32, the threaded groove inside it can force the threaded rod 33 to drive the limit plate 61 to move, thereby pushing each limit plate 61 to move and clamp the filter plate 8. After the position of the filter plate 8 is limited, the slag discharge quality can be further improved. At the same time, it should be noted that when the slag discharge work is performed on the filter plates 8 of different thicknesses, the handle 32 can be rotated to also adjust the moving distance of the threaded rod 33, so that the device can be suitable for filter plates 8 of different specifications.

[0030] like Figure 1-Figure 12As shown, the power assembly 5 includes a gear 54 rotatably installed at the bottom of the slag box 1, the internal gear 41 is meshed with the gear 54, the gear 54 is transmission-connected to the threaded rod 71 through the chain 51, a limiter 52 is slidably installed at the bottom of the slag box 1, the limiter 52 is elastically connected to the bottom of the slag box 1 through the spring telescopic rod 53, two bearings are symmetrically arranged on the limiter 52, and the inner wall of the threaded rod 71 is sleeved on the outer periphery of the bearing.

[0031] A transverse groove is formed on the slag box 1 , and the power assembly 5 further includes a rubber plate 55 arranged in the transverse groove, and the threaded rod 71 movably penetrates the transverse groove and the rubber plate 55 .

[0032] The above scheme is adopted: the output shaft of the motor 4 drives the gear 1 54 to rotate through the internal gear 41, and the gear 1 54 drives the threaded rod 2 71 to rotate through the chain 1 51. When the limit assembly 6 is moved by the clamping assembly 3, the slag discharge assembly 7 moves at the same time, and the threaded rod 2 71 moves in the transverse groove. However, no matter how the threaded rod 2 71 moves, the spring telescopic rod 53 will always support the limiter 52 and the bearing thereon to tighten the chain 1 51, so that the chain 1 51 can better transmit power. The rubber sheet 55 in the transverse groove can prevent water in the slag box 1 from leaking out during the movement of the threaded rod 71 .

[0033] The working principle and use process of the present invention: Place the filter plate 8 between every two adjacent limiting components 6. When the threaded cylinder 31 is rotated by the handle 32, the threaded groove inside it can force the threaded rod 1 33 to drive the limiting plate 61 to move, thereby pushing each limiting plate 61 to move and clamp the filter plate 8; The water inlet of the water pump 22 is connected to an external water source, and then the water pump 22 is started, and the water outlet enters the water storage box 21 on one side, and is sprayed into the slag box 1 through the water tank 23, and finally the water is sprayed onto the filter plate 8 through the notch on the side of the limit plate 61; The output shaft of the motor 4 drives the gear 1 54 to rotate through the internal gear 41, and the gear 1 54 drives the threaded rod 2 71 to rotate through the chain 1 51. When the limit assembly 6 is moved by the clamping assembly 3, the slag discharge assembly 7 moves at the same time, and the threaded rod 2 71 moves in the transverse groove. However, no matter how the threaded rod 2 71 moves, the spring telescopic rod 53 will always support the limiter 52 and the bearing thereon to tighten the chain 1 51 and continue power transmission; The threaded rod 2 71 rotates, and the sleeve plate 72 descends. The gear 2 75 meshes with the staggered tooth plates 63 in sequence. It can be concluded that the gear 2 75 drives the main shaft 73 to swing back and forth during the process of descending. The threaded rod 71 drives the follower ring 78 to rotate, and the follower ring 78 drives the guide wheel 70 to rotate through the chain 77. However, since the guide wheel 70 is eccentrically connected to the guide rod 701, and the guide wheel 70 is rotatably installed on the limit cylinder 79, and the limit cylinder 79 is movably sleeved inside the main shaft 73, the rotation of the guide wheel 70 will push the main shaft 73 to move back and forth through the guide rod 701, and the width of the limit groove 62 is sufficient to support the brush 74 to swing left and right, and will not cause excessive contact between the connection between the main shaft 73 and the brush 74 and rub the edge of the limit groove 62.
