Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an alum throwing device for sewage treatment. Background Art

[0002] The alum throwing device for sewage treatment is a device specially used to throw alum in the sewage treatment process. Alum, as a commonly used water treatment agent, can effectively remove suspended matter and impurities in water and improve water quality. This device automatically or manually throws an appropriate amount of alum evenly into the sewage to help purify and treat the sewage. Through this device, the amount of alum thrown can be controlled more efficiently and accurately, improving the efficiency and quality of sewage treatment.

[0003] A Chinese patent with publication number CN211813608U discloses an alum throwing device for a sewage treatment tank, including a bottom plate, universal wheels, a vertical plate, a torsion device, a buffer device and a receiving trough. Universal wheels are fixed by bolts at the four corners of the bottom surface of the bottom plate. The torsion spring is set so that the rubber layer is squeezed by the forward and reverse rotation of the motor, so that the buffer spring is in a compressed state, so that the throwing trough will not tilt too much to the left, ensuring that the alum discharged from the discharge pipe falls into the throwing trough, and when the rotating motor is reversed, the rebound force of the buffer spring makes the throwing trough have a greater throwing force.

[0004] The alum throwing device of the above patent relies entirely on steel ropes for pulling during the throwing process, and the steel ropes will block the throwing of alum, resulting in poor alum penetration effect and inability to throw alum to farther places, affecting the sewage treatment effect.

[0024] In this embodiment, a support block 7 is provided at one end of the housing 1, and the support block 7 is welded and fixed to one side of the housing 1. The support block 7 is made of rubber material. The support block 7 made of rubber material can limit and support the rotation angle of the storage frame 3, so that the first motor 5 can output and the first motor 5 can output and reset the storage frame 3. Figure 1 As shown, the support block 7 contacts the lower end of the storage frame 3, so as to avoid the storage frame 3 from generating a large noise when alum is put in;

[0025] In this embodiment, a transmission ring 14 is provided at the middle position inside the housing 1, a first transmission rod 15 is provided inside the transmission ring, a first limiting block 18 and a second limiting block 19 are provided at the upper end of the first transmission rod 15 in sequence, and the second limiting block 19, the first limiting block 18 and the first transmission rod 15 are welded and fixed in sequence, a second spring 24 is provided around the first limiting block 18 and the transmission ring 14, and the connection of the second spring 24 allows the first limiting block 18 and the second limiting block 19 to move longitudinally while the transmission ring 14 moves longitudinally, such as Figure 3 and Figure 4As shown, the first limiting block 18 and the second limiting block 19 are arranged in a mirror image, and the mirror image-arranged first limiting block 18 and the second limiting block 19 can make the second spring 24 expand and contract when contacting the connecting roller 22, and the subsequent instantaneous push can be achieved through the expansion and contraction;

[0033] Working principle: when the practical device is used and alum is put in, alum is quantitatively discharged from the storage barrel 2 and falls into the storage frame 3, the second motor 9 is started, and the output shaft of the second motor 9 drives the sector gear 30 to rotate. The rotation of the sector gear 30 can drive the transmission plate 10 to rotate through the transmission tooth groove 29. The rotation of the transmission plate 10 can drive the first telescopic rod 13 and the transmission ring 14 to rotate through the connecting rod 11. The transmission ring 14 is converted from rotational motion to longitudinal linear motion after being restricted by the first limiting rod 17. During the longitudinal movement of the transmission ring 14, the upper end structure is pushed by the second spring 24. After being pushed by the second spring 24, the second limiting block 19 first contacts the connecting roller 22 and pushes the connecting roller 22, pushing and causing the second telescopic rod 21 to contract. After being continuously pushed by the second limiting block 19 When the connecting roller 22 contacts the first limiting block 18, the resilience of the first spring 23 and the resilience of the second spring 24 will instantly push the second transmission rod 20 to move toward the storage frame 3, and the second transmission rod 20 will drive the second tray 26 to move toward the storage frame 3 through the third spring 28, and realize the throwing of alum inside the storage frame 3. After coming out, the storage frame 3 is supported by the support block 7, and the storage frame 3 is reset with the output of the first motor 5. During the resetting process of the storage frame 3, the transmission disk 10 continues to rotate and drives the second limiting block 19 and the first limiting block 18 to move toward the lower end to achieve resetting. During the resetting process, the connecting roller 22 will still be squeezed, and the second spring 24 will be reset after being restricted by the limiting plate 16 and will complete the upward push again with the rotation of the transmission disk 10, thereby realizing the cycle.
