Description

Technical Field

[0001] The utility model belongs to the technical field of cyclone sand settling, in particular to an anti-clogging cyclone sand settling device. Background Art

[0002] The cyclone sand settling machine is a sewage treatment equipment that uses the cyclone principle and centrifugal force to separate the sand and water in the sewage during the sewage pretreatment process, so as to remove the sand and protect the subsequent treatment equipment.

[0003] When the existing cyclone sand settling machine is in use, sewage is usually introduced into the machine body, and then the cyclone centrifugal device in the machine body is driven to centrifugally treat the sewage. The density of sand particles is greater than that of water, so they will move to the inner wall of the machine body and then be discharged through the sand discharge port. During long-term use observation, it is found that when the existing cyclone sand settling machine is in use, the centrifuged sand particles are continuously discharged from the sand discharge port. When there are too many sand particles, they will agglomerate at the sand discharge port and cause blockage.

[0004] To this end, the utility model provides an anti-clogging cyclone sand settling device. Utility Model Content

[0023] 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 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.

[0024] Specific examples are given below.

[0025] like Figures 1 to 4As shown, an anti-clogging cyclone sand settling device described in an embodiment of the utility model comprises a tank body 1; a motor 11 is fixedly connected to the side wall of the tank body 1; a first turntable 12 is fixedly connected to the output end of the motor 11; a second turntable 13 is rotatably connected to the top of the tank body 1; a belt 14 is commonly connected to the side walls of the first turntable 12 and the second turntable 13; a rotating shaft 15 is fixedly connected to the side wall of the second turntable 13; the rotating shaft 15 is hollow; an air pipe 17 is rotatably connected to the inner side wall of the rotating shaft 15; an air pump 16 is connected to the top of the air pipe 17; the air pump 16 is fixedly connected to the top of the tank body 1; a plurality of air holes 18 are opened on the side wall of the air pipe 17; a lower bin 19 is connected to the bottom of the tank body 1; a plurality of legs 110 are fixedly connected to the bottom of the tank body 1; a centrifugal bucket 11 is fixedly connected to the side wall of the rotating shaft 15 1; when working, the sewage is introduced into the centrifugal bucket 111 in the tank body 1, and then the motor 11 is started to drive the first turntable 12 to rotate. At this time, the first turntable 12 is connected to the second turntable 13 through the belt 14, which can drive the second turntable 13, the rotating shaft 15 and the centrifugal bucket 111 to rotate. At this time, the sewage can be subjected to centrifugal cyclone sand settling treatment, and at the same time, the air pump 16 is started to allow the air flow to enter the air pipe 17 and then spray out from the air hole 18, so that the sand particles can be blown away when the sand particles enter the lower bin 19, and then the sand particles are discharged from the lower bin 19. In this step, the air pump 16 is set to connect the air pipe 17 and the air hole 18, so that the sand particles in the sewage can be blown away when they are discharged from the lower bin 19, so as to reduce the situation where agglomeration and blockage are generated in the lower bin 19 when there are more sand particles, so as to improve the stability of sand discharge.

[0026] like Figure 3 to Figure 4 As shown, a plurality of connecting rods 2 are fixedly connected to the bottom of the rotating shaft 15; an auger 21 is fixedly connected to the bottom of the connecting rod 2; during operation, when the rotating shaft 15 rotates, the connecting rod 2 and the auger 21 can be driven to rotate simultaneously. At this time, the auger 21 is a conical spiral structure, which can exert a downward conveying effect on the sand particles when the sand particles are discharged from the lower bin 19, so that the sand particles can be discharged from the lower bin 19 faster. In this step, the connecting rod 2 is arranged to connect the rotating shaft 15 and the auger 21, so that the sand particles can be conveyed when the sand particles are discharged from the lower bin 19, so as to increase the discharge speed of the sand particles, reduce the situation where the sand particles stay in the lower bin 19 and cause blockage, and improve the stability of the sand particle discharge.

[0027] like Figure 4 As shown, a plurality of stirring rods 3 are fixedly connected to the side wall of the connecting rod 2; the stirring rods 3 are arranged in the lower material bin 19; during operation, when the rotating shaft 15 drives the connecting rod 2 to rotate, it will drive the plurality of stirring rods 3 to rotate at the same time. At this time, the stirring rods 3 are located inside the lower material bin 19, and will break up the passing sand particles when rotating. In this step, the stirring rods 3 are connected to the connecting rod 2, and can rotate simultaneously with the connecting rod 2, so as to break up the sand particles when passing through the lower material bin 19, so as to reduce the agglomeration of the sand particles in the lower material bin 19 and cause blockage.

[0028] like Figure 3 As shown, a plurality of fixing rods 4 are fixedly connected to the side wall of the rotating shaft 15; a scraper 41 is fixedly connected to the end of the fixing rod 4; during operation, when the rotating shaft 15 rotates, the fixing rod 4 and the scraper 41 are driven to rotate simultaneously, and at this time, the scraper 41 contacts the funnel-shaped inner wall of the tank body 1, and can scrape its surface during rotation. In this step, the fixing rod 4 is arranged to connect the rotating shaft 15 and the scraper 41, and when the rotating shaft 15 rotates, the scraper 41 is driven to rotate simultaneously, and at this time, the funnel-shaped inner wall of the tank body 1 can be scraped to reduce the sand particles adhering to the inner wall of the tank body 1, resulting in the situation that the sand particles accumulate and remain on the inner wall of the tank body 1 and are difficult to be discharged.

[0029] like Figure 3 and Figure 5 As shown, a pair of fixing plates 5 are fixedly connected to the side walls of the rotating shaft 15; a plurality of damping spring rods 51 are fixedly connected to the top of the fixing plate 5; a fixing block 52 is fixedly connected to the end of the damping spring rod 51; during operation, when the centrifugal bucket 111 rotates, the top of the fixing block 52 is close to the bottom of the centrifugal bucket 111. When the centrifugal bucket 111 shakes during rotation, the bottom of the centrifugal bucket 111 will contact the fixing block 52. At this time, the damping spring rod 51 will continuously shrink and rebound to reduce the amplitude of the shaking of the centrifugal bucket 111. In this step, the fixing plate 5 is provided to connect the damping spring rod 51 and the fixing block 52. When the shaking caused by the rotation of the centrifugal bucket 111 occurs, a buffering and vibration reduction effect can be generated from the bottom of the centrifugal bucket 111, so as to reduce the large shaking amplitude of the centrifugal bucket 111 when the centrifugal bucket 111 rotates, so as to improve the stability of the centrifugal bucket 111 when it rotates.

[0030] like Figure 1 As shown, the side wall of the support leg 110 is fixedly connected to a collecting box 6; a draw box 61 is placed in the collecting box 6; during operation, when sand is discharged from the lower hopper 19, it will fall into the draw box 61 below and be collected. When the collection is completed, the draw box 61 is drawn out of the collecting box 6, the collected sand is poured out and then the draw box 61 is put back into the collecting box 6. In this step, the discharged sand can be collected by setting the collecting box 6 and the draw box 61. The extraction and return setting of the draw box 61 can improve the convenience of taking out the collected sand.

[0031] like Figure 5 As shown, a rubber pad 7 is fixedly connected to the top of the fixing block 52; during operation, when the bottom of the centrifugal bucket 111 is close to the fixing block 52, the rubber pad 7 is located on the top of the fixing block 52, which makes the bottom of the centrifugal bucket 111 contact with the rubber pad 7. In this step, by arranging the rubber pad 7 to connect the fixing block 52, when the centrifugal bucket 111 contacts with the fixing block 52, the damage caused by the friction between the centrifugal bucket 111 and the fixing block 52 can be reduced, thereby playing a protective role.

[0032] Working principle: The sewage is introduced into the centrifugal barrel 111 in the tank body 1, and then the motor 11 is started to drive the first turntable 12 to rotate. At this time, the first turntable 12 is connected to the second turntable 13 through the belt 14, which can drive the second turntable 13, the rotating shaft 15 and the centrifugal barrel 111 to rotate. At this time, the sewage can be subjected to centrifugal cyclone sand settling treatment, and at the same time, the air pump 16 is started to allow the air flow to enter the air pipe 17 and then spray out from the air hole 18, which can blow away the sand particles when they enter the lower bin 19, and then the sand particles are discharged from the lower bin 19. When the rotating shaft 15 rotates, it can drive the connecting rod 2 and the auger 21 to rotate at the same time. At this time, the auger 21 has a conical spiral structure, which can exert a downward conveying effect on the sand particles when the sand particles are discharged from the lower bin 19, so that the sand particles can be discharged from the lower bin 19 faster. When the rotating shaft 15 drives the connecting rod 2 to rotate, it will drive multiple stirring rods 3 to rotate at the same time. At this time, the stirring rod 3 is located in the lower bin 19 When the centrifugal bucket 111 rotates, the top of the fixed block 52 is close to the bottom of the centrifugal bucket 111. When the centrifugal bucket 111 shakes during rotation, the bottom of the centrifugal bucket 111 will be in contact with the fixed block 52. At this time, the damping spring rod 51 will continuously shrink and rebound to reduce the amplitude of the shaking of the centrifugal bucket 111. When the sand is discharged from the lower hopper 19, it will fall into the draw box 61 below and be collected. When the collection is completed, the draw box 61 is drawn out of the collection box 6, the collected sand is poured out and then the draw box 61 is put back into the collection box 6. When the bottom of the centrifugal bucket 111 is close to the fixed block 52, the rubber pad 7 is located at the top of the fixed block 52, which makes the bottom of the centrifugal bucket 111 contact with the rubber pad 7.
