Description

Technical Field

[0001] The utility model relates to the technical field of wet dust collectors, in particular to a parallel water-washing wet dust collector. Background Art

[0002] The parallel water-washing wet dust collector is an air treatment equipment, which is mainly used to remove particulate matter and dust in the gas. It consists of two main parts, a water-washing dust collector and a wet dust collector. These two parts exist in parallel, and each plays a role in removing particulate matter.

[0003] After searching, a parallel water-washing wet dust collector with a publication number of CN214635128U includes a bottom plate, a water tank, a support frame, a motor, a water pump, a dust removal cylinder, a recovery barrel, a filter screen and a water quality detector. A motor is provided on the back of the support frame, and a rotating shaft is provided at the output end of the motor. The rotating shaft is provided with fan blades. The scheme uses the motor and the rotating shaft to drive the fan blades to rotate, thereby driving the gas to rotate to generate centrifugal force to separate the dust and enhance the dust removal efficiency. However, the above technical scheme still has the following shortcomings when it is actually used:

[0004] In this scheme, the dust will be separated from the gas under the action of centrifugal force, and will fly to the inner wall of the dust removal device along the rotation direction of the fan blades. Since a spray system is provided inside the dust removal device, the inner wall of the device is relatively moist, so the dust will adhere to the inner wall of the device under the action of water. After a long period of dust removal work, mud and sand on the inner wall of the device will accumulate and affect the normal circulation of gas, which will reduce the amount of gas entering the device, thereby reducing the efficiency of dust removal and increasing the difficulty of cleaning and maintenance.

[0005] Therefore, it is necessary to design a parallel water-washing wet dust collector to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

The avoidance port has a rectangular structure, and the avoidance port plays a limiting role on the sliding cylinder 8, so that the rotation of the reciprocating screw rod 9 can drive the sliding cylinder 8 to move up and down, and the inner top of the bracket 4 is rotatably connected with the reciprocating screw rod 9, and the reciprocating screw rod 9 is axially connected to the output shaft of the motor 5. The sliding cylinder 8 is threadedly sleeved on the reciprocating screw rod 9, and a connecting pipe 11 is provided at the bottom of the sealing cylinder 7, and a telescopic air bag 12 is provided inside the dust removal tank 1, and the two ends of the telescopic air bag 12 are respectively fixed to the inner top of the dust removal tank 1 and the upper surface of the scraper 3, and the interior of the telescopic air bag 12 is connected to the connecting pipe 11.

[0025] Reference Figure 1 and Figure 2 The water spray assembly includes a water pumping device 6 and a water spraying disc 14. The water pumping device 6 is installed on the dust removal tank 1. The water spraying disc 14 is rotatably connected to the bottom of the scraper 3. The water spraying disc 14 is hollow. A plurality of nozzles 18 are connected to the water spraying disc 14. A rotating joint 15 is embedded on the upper surface of the water spraying disc 14. Under the action of the rotating joint 15, when the water spraying disc 14 rotates, the inside of the water spraying disc 14 can always be connected to the water inlet pipe 16 to ensure the normal operation of the device. The rotating joint 15 is connected to the inside of the water spraying disc 14. The rotating joint 15 is connected to the water inlet pipe 16. The water inlet pipe 16 is connected to the water outlet end of the water pumping device 6. The water spray assembly also includes a rotating part for driving the water spraying disc 14 to rotate.

[0026] Reference Figure 1 The rotating member includes a rotating shaft 13 and a transmission member 17. One end of the rotating shaft 13 is rotatably connected to the inner top of the bracket 4, and the other end of the rotating shaft 13 extends to the inside of the dust removal tank 1. The water spray plate 14 is sleeved on the rotating shaft 13. The rotating shaft 13 is connected to the reciprocating screw 9 through the transmission member 17. Specifically, the transmission member 17 may include two synchronous wheels and a synchronous belt. The synchronous belt is sleeved on the two synchronous wheels to realize the transmission between the two synchronous wheels. The two synchronous wheels are fixedly sleeved on the rotating shaft 13 and the reciprocating screw 9, respectively. In this way, when the motor 5 drives the reciprocating screw 9 to rotate, the rotating shaft 13 can also rotate.

[0027] Reference Figure 2 The cross section of the rotating shaft 13 is a rectangular structure, and an opening for the rotating shaft 13 to pass through is provided on the water spray disc 14. The opening is adapted to the rotating shaft 13, and the opening serves as a limit for the water spray disc 14, so that the rotation of the rotating shaft 13 can drive the water spray disc 14 to rotate.

[0028] Reference Figure 2 The cross sections of the scraper 3 and the telescopic airbag 12 are both annular structures, and the water inlet pipe 16 can pass through the scraper 3 and the telescopic airbag 12 to ensure the stability of the overall structure of the device.

[0029] The specific working principle of the utility model is as follows:

[0030] After the parallel water-washing wet dust collector performs dust removal operation on the gas, the motor 5 is started, and the rotation of the output shaft of the motor 5 drives the reciprocating screw 9 to rotate. Since the outer cross-section of the sliding cylinder 8 is a rectangular structure, and the sealing cylinder 7 is provided with a matching avoidance opening, under the guidance of the avoidance opening, the rotation of the reciprocating screw 9 will not drive the sliding cylinder 8 to rotate, but drive the sliding cylinder 8 to move downward, thereby causing the slide plate 10 to move downward, thereby squeezing the air in the sealing cylinder 7, and the air enters the interior of the telescopic airbag 12 through the connecting pipe 11, and the telescopic airbag 12 is inflated and expanded to become longer. , and then squeeze the scraper 3 downward. On the contrary, when the slide plate 10 moves upward with the rotation of the reciprocating screw rod 9, negative pressure is generated between the bottom of the slide plate 10 and the sealing tube 7, and then the air in the telescopic airbag 12 is sucked back into the sealing tube 7. The telescopic airbag 12 contracts to enable the scraper 3 to move upward, preventing the scraper 3 from affecting the dust removal operation. In this way, in the above operation, the scraper 3 can scrape off dirt such as mud and sand adhering to the inner wall of the dust removal tank 1, preventing it from affecting the normal operation of the dust removal tank 1, ensuring that the gas can normally enter the interior of the device, thereby ensuring the efficiency of dust removal and reducing the maintenance cost of the device;

[0031] While the output shaft of the motor 5 drives the reciprocating screw 9 to rotate, the rotating shaft 13 rotates under the transmission action of the transmission member 17. Under the limiting action of the opening on the rotating shaft 13 and the water spray disc 14, the rotation of the rotating shaft 13 will drive the water spray disc 14 to rotate, and at the same time, the water pumping device 6 is started, and water is pumped into the interior of the water spray disc 14 through the water inlet pipe 16 and sprayed out through the nozzle 18. In this way, during the above process, the water spray disc 14 can move downward under the action of the scraper 3 and rotate under the action of the rotating shaft 13, which greatly increases the water spraying area of ​​the water spray disc 14, and can timely flush the mud and sand scraped out by the scraper 3. The water carries the mud and sand and is discharged from the wastewater discharge pipe 2, thereby ensuring the cleaning effect and improving the cleaning efficiency.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
