Description

TECHNICAL FIELD

[0001] The application relates to the technical field of water treatment, in particular to a hospital sewage purification treatment device. BACKGROUND

[0002] Hospital sewage purification treatment is a crucial link aimed at removing harmful substances in sewage to protect the environment and public health. Currently, the water purification technology widely used in hospitals covers multiple aspects such as physical treatment, chemical treatment and biological treatment. Physical treatment mainly removes suspended solids in sewage through filtration, sedimentation and other means; chemical treatment uses chemical reactions to decompose or precipitate pollutants in sewage; biological treatment uses the metabolic action of microorganisms to degrade organic matter. The comprehensive application of these technologies ensures that hospital sewage can meet strict environmental protection standards before discharge. However, in the water purification process, sludge separation and treatment is still a key link that needs to be optimized.

[0003] Sludge separation plays a crucial role in hospital sewage purification treatment. Suspended solids, silt, organic matter and microorganisms contained in sewage will directly affect the quality of purified water if not effectively separated. Sludge separation technology can effectively remove these impurities, improve water transparency and cleanliness, and ensure that the treated water is clearer and more transparent, meeting the needs of domestic and industrial water. At the same time, sludge separation also helps to reduce the amount of chemical agents used in subsequent treatment steps, reduces treatment costs and improves overall treatment efficiency.

[0004] The existing sludge separation method has certain limitations in treatment efficiency. Due to the complex composition of sludge, it contains a large amount of colloidal substances, organic matter and microorganisms, etc. These substances have strong water absorption and water retention, making it difficult to remove water between sludge particles through conventional mechanical dewatering methods. This leads to difficult sludge dewatering, low treatment efficiency, and affects the smooth progress of the overall water purification process. The cleaning process of the separation equipment after sludge separation is also tedious and time-consuming. Fine particles, fibers and other substances in the sludge are easily accumulated on the separation equipment, forming filter cakes or clogging the filter screen, which not only affects the normal operation of the equipment, but also increases the difficulty of cleaning and maintenance. Traditional cleaning methods often require manual flushing and cleaning, which not only consumes time and effort, but also may cause damage to the equipment. Practical new type content

Obviously, the described embodiments only constitute some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of protection of the present application.

[0022] Figure 1 A whole structure diagram of a hospital sewage purification treatment device provided by the embodiment of the present application is shown. The embodiment of the present application provides a hospital sewage purification treatment device, which comprises:

[0023] The water purification tank 1 is a rectangular water tank with an open top, one short side of the water purification tank 1 is provided with a sludge tank 2, the bottom of the sludge tank 2 is paved with a conveying roller 21, a filter 31 is arranged on the partition between the water purification tank 1 and the sludge tank 2, the filter 31 is rotatably connected to the partition through a filter shaft 34, one end of the filter shaft 34 is connected with a filter motor 3, a torque sensor is arranged on the filter motor 3, the other end of the filter shaft 34 is provided with a shaft fixed terminal 35 and a shock meter 32, the shock meter 32 is fixedly provided with a shock motor 33, a water purification filter screen 13 is arranged in the water purification tank 1, the water purification filter screen 13 is fixed in the water purification tank 1 through a filter screen cross rod 12, the water purification filter screen 13 and the filter screen cross rod 12 are driven by a filter screen motor 11 to slide on the water purification tank 1 along the long axis, the size of the water purification filter screen 13 corresponds to the short cross-sectional area of the inside of the water purification tank 1, a sewage inlet 41 is arranged on the water purification tank 1 between the water purification filter screen 13 and the partition, a filtered water outlet 42 is arranged on the outer wall of the water purification tank 1 away from the partition, the filter motor 3, the torque sensor and the shock motor 33 are connected to a filter controller through wireless network signals.

[0024] The side of the water purification tank 1 provided with the filter screen motor 11 is provided with a slide rail, the filter screen motor 11 drives the water purification filter screen 13 and the filter screen cross rod 12 to move along the slide rail.

[0025] A water level sensor is arranged in the water purification tank 1, a water inlet electronic valve is arranged on the sewage inlet 41, and the water inlet electronic valve is signal connected to the water level sensor; a water outlet electronic valve is arranged on the filtered water outlet 42, and the water outlet electronic valve is signal connected to the water level sensor.

[0026] For example, Figure 1 , 2As shown, the clean water tank 1 and the sludge tank 2 are separated by a partition, and a filter 31 is installed on the partition. When sewage filtration is performed, the filter 31 is placed in the clean water tank, and the sludge, colloidal substances, organic matter, microorganisms and the like in the sewage are pushed onto the filter 31 by the clean water filter screen 13, and then the sludge is turned over to the sludge tank 2 by the filter 31 driven by the filter motor 3 through the filter shaft 34, and then is sent to the baking purification equipment through the conveying roller 21 for purification. A torque sensor is arranged on the filter motor 3, and when the torque sensor detects that the torque of the filter motor 3 driving the filter 31 increases to a set threshold value, it is proved that there is too much sludge and sundries remaining on the filter 31. At this time, the torque sensor triggers a switch signal through the threshold value, which is sent to the filter controller through a wireless network, and then the filter controller controls the vibration motor 33 to start vibration, and the filter 31 is vibrated and cleaned by the vibration ruler 32 driven by the vibration motor 33.

The clean water filter screen 13 is closed after a fixed working time. The clean water tank accumulates sewage, and the clean water filter screen 13 moves towards the partition to perform water purification. When the clean water filter screen 13 moves away from the partition, the purified water backwashes the clean water filter screen 13 to remove the sludge layer accumulated on the surface of the clean water filter screen 13, and then the water outlet electronic valve is opened to re-enter the water purification process.

[0027] A water level sensor is arranged in the clean water tank 1 to adjust the working frequency of the clean water filter screen 13 and the filter 31 through water level change.

[0029] In a possible embodiment, the clean water filter screen 13 is a double-layer mesh skeleton structure, and a filter membrane is movably arranged between the double-layer mesh skeleton structure.

[0030] For example, the filter membrane selects the pore size and pore density according to the demand of water purification rate, and when the filter membrane is seriously worn, the filter membrane is replaced by opening the double-layer mesh skeleton structure.
