Description

Technical Field

[0001] The utility model belongs to the technical field of sedimentation devices, and in particular relates to a sedimentation device for sewage treatment. Background Art

[0002] Sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment. Industrial sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is sewage generated in daily life. It refers to a complex mixture of various forms of inorganic and organic matter, including: 1. Floating and suspended solid particles of different sizes; 2. Colloidal and gel-like diffusions; 3. Pure solutions. According to the nature of sewage, water pollution can be divided into two categories: one is natural pollution; the other is man-made pollution. At present, man-made pollution is the most harmful to water bodies. Water pollution can be mainly divided into different types according to the different pollutants. There are three major categories of pollution: chemical pollution, physical pollution and biological pollution. The main pollutants are: 1. Untreated industrial wastewater; 2. Untreated domestic sewage; 3. Agricultural sewage from the use of large amounts of fertilizers, pesticides and herbicides; 4. Industrial waste and domestic garbage piled up by the river; 5. Soil erosion; 6. Mining sewage. There are many ways to treat sewage, which can generally be summarized as physical, chemical and biological methods. Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in Construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering and other fields are also increasingly entering the daily life of ordinary people.

DETAILED DESCRIPTION

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a sedimentation device for sewage treatment provided by an embodiment of the utility model includes a sedimentation tank 1 and a scraper 5. Moving mechanisms 2 are provided on both sides of the sedimentation tank 1. A mounting frame 3 is provided on the moving mechanism 2. An insertion hole is opened on the mounting frame 3. The mounting frame 3 is located above the sedimentation tank 1. Fixing components 4 are provided at both ends of the upper surface of the mounting frame 3. A connecting plate 6 is fixedly installed on the upper surface of the scraper 5. The lower end of the scraper 5 is inserted through the insertion hole into the sedimentation tank 1, and the lower surface of the scraper 5 is in contact with the bottom of the sedimentation tank 1, the two sides of the lower end of the scraper 5 are in contact with the inner wall of the sedimentation tank 1, the lower surface of the connecting plate 6 is in contact with the upper surface of the mounting frame 3, and the fixing component 4 is used to fix the connecting plate 6.

[0026] The movement of the moving mechanism 2 drives the installation frame 3 to move, and the movement of the installation frame 3 drives the scraper 5 to move in the sedimentation tank 1. The movement of the scraper 5 scrapes the sludge on the bottom and the inner wall of the sedimentation tank 1 together, so that it is convenient to clean the sludge later, saving the time and water resources of the staff. In addition, after the lower surface of the scraper 5 fits with the bottom of the sedimentation tank 1, the lower surface of the connecting plate 6 and the upper surface of the installation frame 3 will fit together. Then, the staff operates the fixing component 4 to fix the connecting block, so that the scraper 5 has moving stability when moving.

[0027] A handle 7 is fixedly mounted on the upper surface of the connecting plate 6 , and thread grooves are provided at both ends of the connecting plate 6 , and the two sets of thread grooves are symmetrically arranged.

[0028] Specifically, the moving mechanism 2 includes a tooth plate 201, a motor 202 and a mounting bar 203. One side of the tooth plate 201 is fixedly installed on one side of the sedimentation tank 1. A gear 204 is fixedly installed on the output shaft end of the motor 202. The gear 204 is meshed with the tooth plate 201. The lower surface of the mounting frame 3 is fixedly installed on the upper surface of the motor 202. One side of the mounting bar 203 is fixedly installed on one side of the sedimentation tank 1, and a slide groove is provided on the other side of the mounting bar 203.

[0029] The output shaft is driven to rotate by the operation of the motor 202, and the rotation of the output shaft drives the gear 204 to rotate on the tooth plate 201, and the tooth plate 201 rotates on the tooth plate 201, thereby forcing the motor 202 to move, and the movement of the motor 202 drives the installation frame 3 to move, thereby achieving the purpose of driving the installation frame 3 to move. In addition, a synchronizer can be used through the two groups of motors 202. The principle of the synchronizer is based on a synchronous rotor generator. It uses a synchronous rotor generator to output a synchronization signal to the motor 202 controller, and sends the AC power synchronized by the controller to the motor 202 rotor, so that the speed of the motor 202 is synchronized with the synchronization signal. The synchronization signal can be other motors 202, a reference signal or an independent reference clock, etc., so that the two groups of motors 202 can run simultaneously.

[0030] Furthermore, a slider 205 is fixedly mounted on one side of the motor 202, and one end of the slider 205 is slidably disposed in the slide groove.

[0031] When the motor 202 moves, the slider 205 is also driven to slide in the slide groove, so that the motor 202 has a guided effect when moving.

[0032] Specifically, the fixing component 4 includes a mounting plate 401, which is T-shaped. A mounting hole is opened at the upper end of the mounting plate 401, and a threaded sleeve 402 is fixedly installed in the mounting hole; a threaded rod 403 is threadedly connected to the threaded sleeve 402, and a rocker 404 is fixedly installed at one end of the threaded rod 403, and the other end of the threaded rod 403 is threadedly connected in the threaded groove.

[0033] After the lower surface of the connecting plate 6 and the upper surface of the mounting frame 3 are fitted together, the staff then rotates the shaking plate 404 to drive the threaded rod 403 to rotate in the threaded sleeve 402, and the other end moves into the threaded groove, thereby fixing the connecting plate 6. When the scraper 5 needs to be taken out of the sedimentation tank 1, the staff rotates the shaking plate 404 again, so that the other end of the threaded rod 403 can be moved out of the threaded groove, and then the scraper 5 can be taken out of the sedimentation tank 1.

[0034] Working principle of this utility model:

[0035] The output shaft is driven to rotate by the operation of the motor 202, and the rotation of the output shaft drives the gear 204 to rotate on the tooth plate 201, and the tooth plate 201 rotates on the tooth plate 201, thereby forcing the motor 202 to move, and the movement of the motor 202 drives the installation frame 3 to move, and the movement of the installation frame 3 drives the scraper 5 to move in the sedimentation tank 1, and the movement of the scraper 5 scrapes the sludge at the bottom of the sedimentation tank 1 and the sludge on the inner wall together, so that it is convenient to clean the sludge later, saving the time and water resources of the staff. In addition, after the lower surface of the scraper 5 is fitted with the bottom of the sedimentation tank 1, the lower surface of the connecting plate 6 and the upper surface of the mounting frame 3 are fitted, and then the staff rotates the shaking plate 404 to drive the threaded rod 403 to rotate in the threaded sleeve 402, and the other end moves into the threaded groove, so as to fix the connecting plate 6, so that the scraper 5 has the stability of movement when moving.
