Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a rotary grille cleaning machine. Background Art

[0002] As we all know, sewage treatment is mainly to purify sewage so that the sewage quality can meet the purification process required by environmental protection. Sewage treatment is mainly used in factories, agriculture, medicine, environmental protection and other fields. The harm of treated sewage to the environment and human body is reduced. There are many types of existing sewage treatment equipment, among which the use of screen machine is relatively large. The main function of the screen machine is to salvage the solid impurities floating in the sewage, so as to achieve the effect of solid-liquid separation of sewage. Due to the large number of impurities floating in the sewage, when the existing screen machine is in use, the salvage hook on the screen machine salvages the impurities in the sewage. A small amount of salvaged impurities are stuck in the gap between the salvage hooks, resulting in poor impurity discharge effect. After the adhered impurities are immersed in water again, the impurities are easy to break away from the salvage hook and cause secondary pollution to the sewage treated by the screen machine, resulting in reduced working effect of the screen machine. At the same time, the impurities are stuck on the salvage hook and gradually increase. The impurities push the front side of the screen machine, which is easy to cause river blockage. When there are many impurities adhering to the screen machine, it is easy to damage the transmission system of the screen machine, resulting in damage to the screen machine and reducing the service life of the screen machine.

[0003] After searching, it was found that in the document with the announcement number CN117802954B, a rotary screen garbage cleaning machine is disclosed, which relates to the technical field of rotary screen garbage cleaning machines. The present invention includes two outer side walls of the frame, each of which is provided with a mounting plate; when installed, the bottom of the frame extends below the liquid surface; it also includes a lifting support arranged in the water body and used to install the frame; the lifting support includes a concrete-cast base, a tube body with a top extending from the top of the base is arranged in the base, an opening is arranged on the peripheral side wall of the base at the bottom of the tube body, and a movable column that moves up and down along its length is arranged in the tube body; a plurality of groups of jacks are arranged at equal intervals on the peripheral side wall of the tube body along its length, and a plug-in structure for inserting into the jack is arranged at the bottom of the movable column. The present invention is provided with a tube body, a movable column and a lifting top column, and matching plug-in structures and jacks are arranged on the tube body and the movable column, so as to adjust the installation height of the garbage cleaning machine according to actual needs during use to adapt to changes in the liquid level. However, this device cannot be adapted to remove impurities that may be stuck between the gaps of the salvage device, which may affect the stability and service life of the device.

[0022] Reference Figure 1 , Figure 2 Two side panels 12 are respectively arranged below both sides of the top plate 11, and a transmission assembly 2 is arranged inside the frame 1. The transmission assembly 2 includes a pair of driving wheels 21, and the pair of driving wheels 21 are respectively fixedly connected to a driving wheel transmission shaft 211. Bearings are respectively arranged at both ends of the driving wheel transmission shaft 211, and the two ends of the driving wheel transmission shaft 211 are respectively arranged on the two side panels 12, so that the driving wheel 21 can rotate under the drive of the driving wheel transmission shaft 211.

[0023] Reference Figure 1 , Figure 2The driving wheel 21 is arranged below one side of the top plate 11, and a pair of first driven wheels 22 are arranged below the other side of the top plate 11, and the pair of first driven wheels 22 are respectively fixedly connected to a first driven wheel transmission shaft 221, and bearings are respectively arranged at both ends of the first driven wheel transmission shaft 221, and both ends of the first driven wheel transmission shaft 221 are respectively arranged on the two side plates 12. The first driven wheel 22 is arranged on one side of the driving wheel 21, and a pair of second driven wheels 23 are arranged below the other side of the horizontal position of the driving wheel 21, and a pair of second driven wheels 23 are respectively fixedly connected to a second driven wheel transmission shaft 231, and bearings are respectively arranged at both ends of the second driven wheel transmission shaft 231, and both ends of the second driven wheel transmission shaft 231 are respectively arranged on the two side plates 12, so that the first driven wheel 22 and the second driven wheel 23 can rotate on the transmission shafts where they are located.

[0024] Reference Figure 2 , Figure 3 The driving wheel 21, the first driven wheel 22 and the second driven wheel 23 are respectively provided with toothed discs meshing with the chain 24. The two sets of driving wheels 21, the first driven wheel 22 and the second driven wheel 23 arranged on the two side plates 12 are respectively meshed with a chain 24. A plurality of fixing rods 25 are arranged between the two chains 24. The two ends of the fixing rods 25 are respectively fixedly connected to the chains 24. The chain 24 connects the driving wheel 21, the first driven wheel 22 and the second driven wheel 23 arranged on the same side, so that after the driving wheel 21 rotates, it drives the chain 24, and then the chain 24 drives the first driven wheel 22 and the second driven wheel 23 to rotate, so that the fixing rods 25 arranged on the two chains 24 follow the chains 24 to rotate along the set route.

[0025] Reference Figure 4 , Figure 5 , Figure 6 The tooth rake assembly 3 is arranged on the fixed rod 25, and the tooth rake assembly 3 is fixed to the fixed rod 25 through a fixer 31. The fixer 31 is in a circular ring shape, and its inner ring is provided with a fixer inner bearing 311. The inner ring of the fixer inner bearing 311 is fixedly connected to the fixed rod 25, so that the tooth rake assembly 3 can follow the fixed rod 25 to rotate along the set route, thereby removing impurities in the water from the sewage cleaning machine.
