Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to an automatic cleaning device for inclined pipes of a high-density pool. Background Art

[0002] The inclined tube high-density tank is a highly efficient combined sedimentation tank based on the shallow tank theory. When water flows through the inclined tube, its suspended particles will settle on the inclined tube and slide down to the bottom of the tank under the action of gravity. Inclined tube sedimentation tanks are widely used in various sewage treatment fields. Through this method, suspended particles in the water can be effectively removed and the effluent quality can be improved.

[0003] However, during operation, sludge often accumulates on the inclined tube, which reduces the water discharge efficiency. In severe cases, the inclined tube may sink or collapse. In addition, algae will grow on the inclined tube in summer, affecting the water discharge effect, so the inclined tube needs to be cleaned regularly. Conventional cleaning methods require manual use of high-pressure water guns to clean the high-density pool inclined tube from top to bottom. The cleaning degree is difficult to control and may cause the instantaneous suspended solids in the effluent to be too high, affecting normal production.

[0004] Therefore, it is necessary to design an automatic cleaning device for the inclined tubes of high-density pools to reduce manpower consumption and ensure the cleaning effect. Summary of the invention

DETAILED DESCRIPTION

[0020] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] See Figure 1As shown, the automatic cleaning device of the high-density pool inclined tube comprises a high-density pool body 1, an inclined tube 2, a central rotating shaft 5, a scraper arm 9, an air inlet pipe 4, an air outlet pipe 6, a bearing 8, and a compressor 3; the inclined tube 2 is installed at the upper end of the high-density pool body 1; the central rotating shaft 5 is installed in the central position of the high-density pool body 1 along the depth direction, the top is movably installed at the end of the high-density pool body 1, and the bottom extends out of the high-density pool body 1 and is installed through a fixed seat, and can rotate; the air inlet pipe 4 is installed inside the central rotating shaft 5, one end extends out of the top of the central rotating shaft 5 and is connected to the compressor 3 outside the high-density pool body 1, and the other end extends out of the outer wall of the central rotating shaft 5 and is connected to the air outlet pipe 6 inside the high-density pool body 1; the scraper arm 9 is symmetrically installed along the outer wall of the central rotating shaft 5, and is installed below the inclined tube 2; the air outlet pipe 6 is installed on the upper end surface of the scraper arm 9; the air inlet pipe 4 and the air outlet pipe 6 are connected by a bearing 8.

[0022] It also includes a scraper 10, the upper end surface of the scraper 10 is installed at the lower end of the scraper arm 9; the lower end surface of the scraper 10 is installed at an angle with the horizontal plane. The sewage flows through the inclined pipe to complete the mud and water separation, the sludge settles to the bottom of the pool, and the supernatant is discharged for the next step of treatment.

[0023] As a specific implementation of the utility model, an air outlet pipe 6 is fixed on the scraper arm 9, and nozzles 7 are evenly arranged on the pipe. The nozzles are installed to keep a horizontal angle of 45-75° with the air outlet pipe, preferably 60°.

[0024] A horizontal angle of 45-75° is set between the nozzle and the air transmission pipe so that the angle of the compressed air spray is parallel to the inclined pipe, which can clean the inclined pipe while reducing the impact on the inclined pipe.

[0025] See Figure 2-4 As shown, the bearing 8 includes an inner ring 11, rolling elements 12, a retaining frame 13, an outer ring 14, an outer column 15, and an inner column 16; the retaining frame 13 is installed between the inner ring 11 and the outer ring 14, and the rolling elements 12 are rollingly installed on the retaining frame 13; one end of the outer column 15 is connected to the outer ring 14, and the other end is connected to the end of the intake pipe 4; one end of the inner column 16 is connected to the inner ring 11, and the other end is connected to the outlet pipe 6.

[0026] As a specific implementation of the utility model, the outer column 15 is connected to the end of the air inlet pipe 4 by welding, and the inner ring 11 is connected to the end of the air outlet pipe 6 by welding.

[0027] See Figure 5As shown, the specific procedure for cleaning the inclined tube is as follows: step one: start the air compressor 3, and blow the compressed gas out through the nozzle 7 to clean the inclined tube 2; step two: shut down the air compressor after running for 10-30 seconds; step three: after the air compressor is shut down for 2-8 minutes, determine whether the air compressor has been turned on 6-12 times after the cleaning program starts. If the set number of times has not been reached, return to step one to continue cleaning the inclined tube. If the set number of times has been reached, the cleaning program ends and the high-density pool resumes normal operation.

[0028] During cleaning, the water disturbance caused by the nozzle can cover the 30-60° fan-shaped area of ​​the inclined tube. Therefore, in a single cleaning process, the air compressor only needs to be turned on 6-12 times to complete the cleaning of the inclined tube. It takes about 8-40 minutes for the central drive shaft to rotate one circle. The time interval for each air compressor startup can be calculated based on the rotation cycle and the number of times the inclined tube needs to be flushed. After the inclined tube cleaning program is started, the air compressor will be turned off after a short work period of 10-30 seconds. After the air compressor is turned off for the set time, it will be turned on again. At this time, the central drive shaft has rotated a certain angle and the next area can be flushed. Intermittent inclined tube flushing can prevent excessive disturbance of the pool body caused by continuous flushing and excessive suspended matter in the instantaneous water outlet.

[0029] Example

[0030] The rotation cycle of the central drive shaft of the high-density pool of a sewage treatment plant is 30 minutes. The specific procedure for cleaning the inclined pipe is as follows: step 1: start the air compressor 3, and the compressed gas is blown out through the nozzle 7 to clean the inclined pipe 2; step 2: the air compressor is turned off after running for 20 seconds; step 3: after the air compressor is turned off for 4 minutes and 40 seconds, determine whether the air compressor has been turned on 6 times after the cleaning program starts. If the set number of times has not been reached, return to step 1 to continue cleaning the inclined pipe. If the set number of times has been reached, the cleaning program ends and the high-density pool resumes normal operation.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
