Description

Technical Field

[0001] This invention relates to the field of ship sewage treatment technology, and in particular to a ship sewage treatment device. Background Technology

[0002] Currently, with the rapid advancement and innovation of global maritime technology, ship designs are increasingly trending towards larger and more specialized sizes. These behemoths frequently traverse the vast oceans, performing a wide variety of maritime missions. Against this backdrop, the problem of sewage generated by shipboard personnel has become increasingly prominent, and how to efficiently and environmentally treat this sewage has become a critical issue that urgently needs to be addressed. To this end, shipboard sewage treatment systems have emerged and play an indispensable role in practical applications.

[0003] Existing ship wastewater treatment facilities employ a relatively complete wastewater treatment process. First, untreated raw domestic sewage is guided through a separation screen into the primary treatment chamber. The separation screen effectively filters out large solid particles such as cigarette butts and plastics, ensuring the smooth progress of subsequent treatment steps. The pre-filtered sewage is then discharged into the aeration chamber, an active environment filled with oxygen and aerobic bacteria. Using oxygen as an energy source, the aerobic bacteria gradually decompose organic pollutants in the sewage into harmless carbon dioxide, water, and other inorganic substances, thus achieving preliminary wastewater purification.

[0004] Following this, the aerated wastewater continuously flows into the sedimentation chamber. During this stage, activated sludge and scum enter the sedimentation chamber along with the wastewater. After sedimentation, the activated sludge and scum return to the aeration chamber, while the clean wastewater at the top of the sedimentation chamber flows into the disinfection chamber for disinfection. However, the sedimentation process is not without its challenges. As new batches of domestic wastewater continuously flow in, the activated sludge and scum already deposited at the bottom of the sedimentation chamber may be stirred up by the newly flowing wastewater. This phenomenon, known as "disturbance," directly weakens the sedimentation chamber's intended settling and separation effect, leading to decreased treatment efficiency and incomplete water purification. Summary of the Invention

[0007] Furthermore, a lower support frame is fixedly installed at the lower end of the outer cylinder.

[0008] Furthermore, the upper wall of the outer cylinder is provided with a plurality of mounting through holes evenly distributed in a circular shape. The upper end of the sedimentation cylinder is rotatably connected to the mounting through holes. A liquid inlet hole is provided at the center of the upper end of the sedimentation cylinder. A branch liquid inlet pipe passes through the liquid inlet hole at the upper end of the sedimentation cylinder and is inserted into the lower part of the cavity of the sedimentation cylinder. The branch liquid inlet pipe is rotatably connected to the liquid inlet hole.

[0009] Furthermore, a piston is installed inside the cavity of the sedimentation cylinder. A guide hole is located at the center of the piston, and a branch inlet pipe passes through this guide hole, forming a sliding, sealed connection. A positioning ring is fixedly installed at the center of the piston, and a positioning groove is provided on the outer wall of the positioning ring. A retaining ring is located at the lower end of the branch inlet pipe, and the retaining ring is placed at the lower end of the piston. A guide sleeve is fixedly installed at the center of the upper end of the sedimentation cylinder, and a guide hole is provided on the guide sleeve. The guide hole is coaxially aligned with the inlet hole of the sedimentation cylinder. The branch inlet pipe... The piston is inserted into the lower part of the cavity of the sedimentation cylinder through the guide hole of the guide sleeve and the liquid inlet hole at the upper end of the sedimentation cylinder. The lower end of the guide sleeve is provided with an annular placement groove, which is connected to the cavity of the sedimentation cylinder. The upper end of the piston is connected to the top wall of the annular placement groove by a spring. The outer wall of the guide sleeve is provided with an insertion hole, which is connected to the guide hole of the guide sleeve. The insertion hole of the guide sleeve corresponds to the positioning groove of the positioning ring. An electromagnetic lock is installed at the upper end of the sedimentation cylinder, and the locking tongue of the electromagnetic lock corresponds to the insertion hole of the guide sleeve.

[0010] Furthermore, the bottom of the upper wall of the outer cylinder is provided with multiple fixed sleeves, which correspond to the adsorption cylinder and are rotatably connected to the upper end of the adsorption cylinder.

[0011] Furthermore, the sedimentation cylinder and the adsorption cylinder are respectively connected to the driving mechanism. The driving mechanism includes a motor, a driving gear, a driven gear, and a first gear ring. A through hole is provided on the upper end wall of the outer cylinder. The motor is fixedly installed on the upper end wall of the outer cylinder. The motor shaft passes through the through hole on the upper end wall of the outer cylinder and is fixedly connected to the driving gear.

[0013] Compared with the prior art, the present invention has the following outstanding advantages: 1. The present invention has multiple sedimentation mechanisms. When one sedimentation tank is filled with sewage, the sedimentation tank is closed, and the sewage is then injected into other sedimentation tanks in sequence. Therefore, there will be no continuous flow of sewage into the sedimentation tank, which will disturb the sediment inside and affect the sedimentation effect. 2. When the motor of the drive mechanism of the present invention rotates forward, it can drive the sedimentation cylinder to rotate, generating centrifugal force on the sewage in the sedimentation cylinder and accelerating the sedimentation effect. When the motor rotates in reverse, it can drive the adsorption cylinder to rotate, so that the adsorption cylinder can fully contact the sewage and enhance the adsorption effect. 3. In this invention, multiple brush rollers are installed between the sedimentation cylinder and the adsorption cylinder. When the sedimentation cylinder or the adsorption cylinder rotates, it can drive the brush rollers to rotate, so that the brush rollers clean the inner wall of the adsorption cylinder and wash away the oil stains attached to the inner wall of the adsorption cylinder to prevent them from affecting the adsorption effect.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-3 As shown, the present invention includes an outer cylinder 1, a sedimentation mechanism 2, and an adsorption mechanism 3.

[0017] The outer cylinder 1 has multiple sedimentation mechanisms 2 evenly distributed in a circular shape installed inside its cavity. Each sedimentation mechanism 2 has a corresponding adsorption mechanism 3 installed on its outer side. A main inlet pipe 101 is installed on the upper wall of the outer cylinder 1. The main inlet pipe 101 is connected to the sedimentation mechanism 2 through a branch inlet pipe 201 and a first solenoid valve 206. A main drain pipe 102 is installed on the lower wall of the outer cylinder 1. The lower end of the sedimentation mechanism 2 is connected to the main drain pipe 102 through a branch drain pipe 204 and a second solenoid valve 205.

[0018] The outer wall of the outer cylinder 1 is provided with a drain pipe 103, which is connected to the fourth solenoid valve 104. The drain pipe 103 is connected to the cavity of the outer cylinder 1, and a lower support frame 105 is fixedly installed at the lower end of the outer cylinder 1.

[0019] The main inlet pipe 101 is connected to the aeration equipment, and wastewater flowing out of the aeration equipment enters the main inlet pipe 101. The main outlet pipe 102 is connected to the aeration equipment, and wastewater flowing out of the main outlet pipe 102 re-enters the aeration equipment. The outlet pipe 103 is connected to the disinfection equipment, and wastewater flowing out of the outlet pipe 103 enters the disinfection equipment. The aeration equipment and disinfection equipment are existing devices, and their specific structures will not be described in detail.

[0020] The sedimentation mechanism 2 includes a sedimentation cylinder 202. The upper part of the sedimentation cylinder 202 has multiple circumferentially distributed liquid outlet pipes on its outer wall. The lumens of the liquid outlet pipes are connected to the sedimentation cylinder 202 and connected to a third solenoid valve 209. The lower end of the sedimentation cylinder 202 has a sewage outlet. The sewage outlet is connected to the main sewage pipe 102 in sequence through a rotary joint 203, a branch sewage pipe 204, and a second solenoid valve 205. The lower part of the sedimentation cylinder 202 is conical, which facilitates the discharge of activated sludge and scum at the bottom of the sedimentation cylinder 202 with the sewage.

[0021] The upper wall of the outer cylinder 1 is provided with a plurality of mounting through holes evenly distributed in a circular shape. The upper end of the sedimentation cylinder 202 is rotatably connected to the mounting through holes. The center of the upper end of the sedimentation cylinder 202 is provided with a liquid inlet hole. The branch liquid inlet pipe 201 passes through the liquid inlet hole at the upper end of the sedimentation cylinder 202 and is inserted into the lower part of the cavity of the sedimentation cylinder 202. The branch liquid inlet pipe 201 is rotatably connected to the liquid inlet hole.

[0022] like Figures 6-8 As shown, in the optimized scheme, a piston 6 is installed in the cavity of the sedimentation cylinder 202. A guide hole is provided at the center of the piston 6. The branch inlet pipe 201 passes through the guide hole of the piston 6 and the two are slidably sealed together. A positioning ring 601 is fixedly installed at the center of the piston 6. A positioning groove is provided on the outer wall of the positioning ring 601. A retaining ring is provided at the lower end of the branch inlet pipe 201 and is placed at the lower end of the piston 6.

[0023] A guide sleeve 207 is fixedly installed at the center of the upper end of the sedimentation cylinder 202. The guide sleeve 207 is provided with a guide through hole, which is arranged coaxially with the liquid inlet hole of the sedimentation cylinder 202. The branch liquid inlet pipe 201 passes through the guide through hole of the guide sleeve 207 and the liquid inlet hole at the upper end of the sedimentation cylinder 202 in sequence and is inserted into the lower part of the cavity of the sedimentation cylinder 202. The lower end of the guide sleeve 207 is provided with an annular placement groove, which is connected to the cavity of the sedimentation cylinder 202. The upper end of the piston 6 is connected to the top wall of the annular placement groove through a spring. When the piston 6 moves upward, it compresses the spring and the compressed spring can be placed in the annular placement groove.

[0024] The guide sleeve 207 has an insertion hole on its outer wall, which communicates with the guide through hole of the guide sleeve 207. The insertion hole of the guide sleeve 207 corresponds to the positioning groove of the positioning ring 601. An electromagnetic lock 7 is installed at the upper end of the sedimentation cylinder 202. The locking tongue of the electromagnetic lock 7 corresponds to the insertion hole of the guide sleeve 207. When the positioning groove of the positioning ring 601 moves to the insertion hole position of the guide sleeve 207, the locking tongue of the electromagnetic lock 7 is inserted into the positioning groove of the positioning ring 601 to fix the piston 6.

[0025] In the optimized scheme, a first liquid level sensor and a second liquid level sensor are installed on the inner wall of the sedimentation tank 202. The first liquid level sensor is installed at the upper end of the inner wall of the sedimentation tank 202, and the second liquid level sensor is installed at the height of the outlet pipe on the inner wall of the sedimentation tank 202. The first liquid level sensor is connected to the first solenoid valve 206 and the solenoid lock 7 through a circuit. The second liquid level sensor is connected to the second solenoid valve 205, the third solenoid valve 209 and the solenoid lock 7 through a circuit. The circuit is existing technology, and its specific structure will not be described in detail.

[0026] When the sewage reaches the position of the first liquid level sensor, the sewage fills the sedimentation tank 202, the first solenoid valve 206 closes, and the locking tongue of the electromagnetic lock 7 is inserted into the positioning groove of the positioning ring 601.

[0027] When the clean sewage is discharged from the top of the sedimentation tank 202, and the sewage reaches the position of the second liquid level sensor, the third solenoid valve 209 closes, the second solenoid valve 205 opens, and the latch of the electromagnetic lock 7 retracts.

[0028] The adsorption mechanism 3 includes an adsorption cylinder 301, which is sleeved on the outside of the sedimentation cylinder 202. The lower end of the adsorption cylinder is rotatably connected to the outer wall of the sedimentation cylinder 202. The bottom of the upper wall of the outer cylinder 1 is provided with multiple fixed sleeves, which correspond to the adsorption cylinder 301 and are rotatably connected to the upper end of the adsorption cylinder 301.

[0029] In the optimized scheme, the sidewall of the adsorption cylinder 301 is composed of activated carbon.

[0030] like Figure 4 and 5 As shown, the sedimentation cylinder 202 and the adsorption cylinder 301 are respectively connected to the drive mechanism 4. The drive mechanism 4 includes a motor 404, a driving gear 402, a driven gear 401, and a first gear ring 403. The upper end wall of the outer cylinder 1 is provided with a through hole. The motor 404 is fixedly installed on the upper end wall of the outer cylinder 1. The motor shaft of the motor 404 passes through the through hole on the upper end wall of the outer cylinder 1 and is fixedly connected to the driving gear 402. The driven gear 401 is connected to the upper end of the sedimentation cylinder 202 through a one-way bearing. The first gear ring 403 is connected to the inner wall of the adsorption cylinder 301 through a one-way bearing. The driving gear 402 meshes with the driven gear 401 and the first gear ring 403 respectively. When the motor 404 drives the drive gear 402 to rotate forward, the drive gear 402 drives the sedimentation cylinder 202 to rotate through the driven gear 401. At this time, due to the action of the one-way bearing, the first gear ring 403 rotates idly and does not drive the adsorption cylinder 301 to rotate. When the motor 404 drives the drive gear 402 to rotate in reverse, the drive gear 402 drives the adsorption cylinder 301 to rotate through the first gear ring 403. At this time, due to the action of the one-way bearing, the driven gear 401 rotates idly and does not drive the sedimentation cylinder 202 to rotate.

[0031] A brushing mechanism 5 is installed between the outer wall of the sedimentation cylinder 202 and the inner wall of the adsorption cylinder 301. The brushing mechanism 5 includes a planetary gear 502, a second gear ring 501, and a brush roller 503. A rotating ring 208 is installed on the outer wall of the sedimentation cylinder 202. A sealing ring is installed between the rotating ring 208 and the inner wall of the adsorption cylinder 301. A second gear ring 501 is installed on the inner wall of the adsorption cylinder 301. The rotating ring 208 has multiple through holes evenly distributed in a circumferential shape. The upper end of the brush roller 503 shaft passes through the through holes on the rotating ring 208 and is fixedly connected to the planetary gear 502. The planetary gear 502 meshes with the second gear ring 501. The brush roller 503 shaft is rotatably connected to the through holes of the rotating ring 208. The bristles of the brush roller 503 are in contact with the inner wall of the adsorption cylinder 301. When the sedimentation cylinder 202 rotates, it drives the brush roller 503 to rotate. The planetary gear 502 moves along the second gear ring 501, which enables the brush roller 503 to rotate around the inner wall of the adsorption cylinder 301 while rotating on its own axis. When the adsorption cylinder 301 rotates, the second gear ring 501 drives the planetary gear 502 to rotate on its own axis, and the planetary gear 502 drives the brush roller 503 to rotate, thereby brushing the inner wall of the adsorption cylinder 301 and preventing oil stains from adhering to the inner wall of the adsorption cylinder 301 and affecting the adsorption effect.

[0032] The operation process is as follows: When using this invention, open a first electromagnetic valve 206 to allow sewage to enter the corresponding sedimentation tank 202 through the main inlet pipe 101 and the branch inlet pipe 201. The sewage injected into the sedimentation tank 202 drives the piston 6 to rise, and the piston 6 drives the positioning ring 601 to move. When the positioning groove of the positioning ring 601 moves to the insertion position of the guide sleeve 207, the locking tongue of the electromagnetic lock 7 is inserted into the positioning groove of the positioning ring 601 to fix the piston 6. At this time, close the first electromagnetic valve 206 and open another first electromagnetic valve 206 to allow sewage to enter another sedimentation tank 202. Repeat the above steps to inject sewage into the sedimentation tank 202 in sequence.

[0033] When one of the sedimentation tanks 202 is filled with sewage, the drive mechanism 4 is started. When the motor 404 drives the drive gear 402 to rotate forward, the drive gear 402 drives the sedimentation tank 202 to rotate through the driven gear 401. During the rotation of the sedimentation tank 202, the sewage inside generates centrifugal force, thereby accelerating the sedimentation of impurities inside the sewage.

[0034] After the sewage in the sedimentation tank 202 has settled, the third solenoid valve 209 is opened, allowing the clean sewage at the upper part of the sedimentation tank 202 to flow into the adsorption tank 301. At this time, the drive mechanism 4 is started. When the motor 404 drives the drive gear 402 to reverse, the drive gear 402 drives the adsorption tank 301 to rotate through the first gear ring 403. The sewage in the adsorption tank 301 comes into full contact with the inner wall of the adsorption tank 301, so that the sewage after adsorption treatment by the adsorption tank 301 is discharged into the outer cylinder 1.

[0035] After the clean sewage in the upper part of the sedimentation tank 202 has completely flowed out, close the third solenoid valve 209 and open the second solenoid valve 205, causing the locking tongue of the solenoid lock 7 to retract. The spring drives the piston 6 to reset, and the piston 6 pushes the remaining sewage in the sedimentation tank 202 to pressurize the sewage, so that the sewage can carry the settled impurities into the main sewage pipe 102.

[0036] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes made to it without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
