Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to energy-saving and environmentally friendly medical wastewater liquid separation equipment. Background Art

[0002] Medical wastewater usually contains a large amount of harmful substances. If it is discharged into the environment at will, it will cause great harm to water resources and the ecological environment. Therefore, modern hospitals are generally equipped with medical sewage treatment facilities to treat medical wastewater to purify the wastewater and meet the discharge requirements;

[0003] Physical treatment is the first step in the treatment of medical wastewater. This step mainly uses physical phenomena to separate solid and suspended matter in wastewater, and passes wastewater through a filter screen to intercept large particles such as paper scraps, cloth, bandages, etc., to avoid clogging subsequent treatment facilities.

[0004] It has been found in actual use that the existing medical wastewater liquid separation equipment has the following shortcomings:

[0005] When the wastewater is intercepted by the filter, it flows directly, the filter intercepts the solid impurities and discharges the wastewater. The filter is in passive contact with the wastewater and solid impurities, resulting in a relatively low separation efficiency. The larger fixed impurities are physically intercepted by the filter. Since the fixed impurities are intercepted, they stick to the filter and accumulate on the filter to block the filter, resulting in a large local filtration pressure on the filter, causing the filtration capacity of the filter to continue to decline, affecting the treatment efficiency of medical wastewater;

[0006] In addition, the fixed impurities generated by solid-liquid separation accumulate and result in low utilization efficiency of the filter screen, requiring frequent replacement of the filter screen to ensure the filtering effect, which increases the cost of sewage treatment and interrupts the sewage treatment cycle. At the same time, it increases the workload of the staff, which is not conducive to energy conservation and environmental protection.

[0007] In addition, the fixed impurities generated by solid-liquid separation accumulate inside the sewage treatment equipment, which requires the sewage treatment work to be interrupted, the equipment to be opened and the fixed impurities to be cleaned out, making the removal of garbage generated by solid-liquid separation of medical wastewater inconvenient;

[0008] Therefore, the present application provides energy-saving and environmentally friendly medical waste liquid separation equipment to meet the needs. Utility Model Content

[0010] The technical problem to be solved by the utility model is to provide an energy-saving and environmentally friendly medical waste water liquid separation device to solve the problems of the existing energy-saving and environmentally friendly medical waste water liquid separation devices.

[0011] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0012] An energy-saving and environmentally friendly medical waste liquid separation device comprises: a sewage treatment box, a liquid inlet pipe, a guide bucket, a sealing box, a transmission motor, a rotating shaft, a separation disc, a filter screen, a discharge hopper, a collection box, a connecting rod, a connecting pipe, a material guide seat, a drain pipe, a waste box and a cover plate, wherein a liquid inlet pipe is installed on one side of the top of the sewage treatment box, a drain pipe is installed on one side of the bottom of the sewage treatment box, a guide bucket is installed at the upper end of the sewage treatment box, a sealing box is installed at the top of the sewage treatment box, a transmission motor is installed inside the sealing box, a separation disc is installed at the lower end of the transmission motor through a rotating shaft, a filter screen is installed at the lower end of the separation disc, a discharge port is opened on the side wall of the separation disc, and a discharge hopper is installed on the outer side of the separation disc;

[0014] Preferably, the rotating shaft vertically penetrates downward through the guide bucket and extends to the outer end of the guide bucket, and the separation plate is located at the lower end of the bottom opening of the guide bucket.

[0015] Preferably, the separation disc is disc-shaped, and the diameter of the separation disc is the same as the diameter of the lower end of the guide bucket.

[0016] Preferably, two groups of discharge ports are provided on the side wall of the separation disk, and the discharge hopper is installed at the outer ends of the two groups of discharge ports of the separation disk.

[0017] Preferably, the discharge hopper is trumpet-shaped and extends outward to the bottom outer end of the guide hopper.

[0018] Preferably, the material collection box is cylindrical, and the connecting pipe inside the material collection box is located directly below the separation disk, and the diameter of the connecting pipe is the same as the diameter of the separation disk.

[0019] Preferably, the material guiding seat is trumpet-shaped and extends downward to the lower end of the material collecting box, and the bottom diameter of the material guiding seat is the same as the diameter of the material collecting box.

[0020] Preferably, the waste box is in a circular shape and surrounds the outer end of the sewage treatment box, and the waste box is connected to the interior of the sewage treatment box, and the waste box is located at the outer end of the side of the material guide seat.

[0021] Preferably, the cover plates are provided in two groups, and the two groups of cover plates are provided in a semicircular arc shape. Compared with the prior art, the utility model has at least the following beneficial effects:

[0022] 1. When the medical waste water discharged from the liquid inlet pipe into the sewage treatment tank is diverted downward through the diversion bucket, it contacts the high-speed rotating separation disc. The filter net at the lower end of the separation disc intercepts the solid impurities in the medical waste water, and the liquid directly flows downward through the filter net. During the separation process, the intercepted solid impurities are large in mass and are thrown outward from the filter net by the centrifugal force when the separation disc rotates. They quickly accumulate on the inner wall of the separation disc, which not only speeds up the separation of medical waste water and solid impurities, but also prevents solid impurities from sticking to the filter net and clogging the filter net, thereby ensuring the filtering capacity of the filter net and improving the treatment efficiency of medical waste water.

[0023] 2. Under the action of centrifugal force when the separation disc rotates, the intercepted solid impurities are thrown outward from the filter net, quickly accumulate on the inner wall of the separation disc, and are thrown outward through two sets of discharge ports. The solid impurities thrown outward from the discharge port are thrown out through the trumpet-shaped discharge hopper and fall downward into the collection box, which can quickly discharge the separated solid impurities from the separation disc to the outside, ensuring the smoothness of solid-liquid separation, and effectively preventing the long-term solid-liquid separation in the separation disc from accumulating dirt and impurities and causing the filter net to be blocked, which is beneficial to prolonging the service life of the filter net, reducing the frequency of replacing the filter net, and making sewage treatment more energy-saving and environmentally friendly;

[0024] 3. The solid impurities entering the collecting box can be discharged into the waste box at the outer end of the sewage treatment box through the trumpet-shaped guide seat. The solid impurities generated during the solid-liquid separation of medical wastewater can be processed through the waste box at the outer end of the sewage treatment box, making the garbage removal generated by the solid-liquid separation of medical wastewater more convenient.
