Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a medical wastewater filtering device. Background Art

[0002] Medical wastewater refers to sewage discharged from hospitals into the natural environment or urban pipelines. The main pollutants contained in hospital sewage are pathogens, organic matter, floating and suspended matter, radioactive pollutants, etc. In the pretreatment process of medical wastewater in the prior art, most of the pollutants are separated on the surface of the filter. Since the staff needs to disassemble the filter for regular cleaning, the filter and the device in the prior art are mostly connected by a snap-on structure. However, in order to ensure the separation efficiency of the device, the sewage inlet valve is mostly in a fully open state. In this state, the filter is subjected to a large impact force from the sewage. After working for a long time, the snap-on joint between the filter and the device is easily deformed and stuck, and is difficult to remove, which not only reduces the service life but also affects the separation effect of the device. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a medical waste water filtering device, which has the advantage of greatly reducing the impact force of the falling sewage while ensuring that the water intake volume remains unchanged. It solves the problem that most of the sewage inlet valves in the prior art are in a fully open state. In this state, the filter screen is subjected to a large impact force from the sewage. After working for a long time, the joint between the filter screen and the device is easily deformed and stuck, making it inconvenient to remove, which not only reduces the service life but also affects the separation effect of the device.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A medical waste water filtering device comprises a shell mechanism as a main body of the device, the shell mechanism comprises an outer shell, a discharge mechanism for treating separated sewage is arranged at the bottom of the shell mechanism, a buffer mechanism for buffering and releasing sewage is arranged inside the shell mechanism, a filtering mechanism for filtering sewage is arranged below the buffer mechanism, the buffer mechanism comprises an inlet pipe fixedly connected to the top of the outer shell, a transverse pipe a is fixedly connected to the bottom end of the inlet pipe, branch pipes a are fixedly connected to the bottoms of both ends of the transverse pipe a, the bottom ends of the two branch pipes a are fixedly connected to the transverse pipe b, the bottom of the transverse pipe b is fixedly connected to a plurality of branch pipes b, a plurality of fixed circular plates are fixedly connected to the two side walls of the outer shell, buffer blades are rotatably connected between the opposite fixed circular plates, and special-shaped partitions are fixedly connected between adjacent fixed circular plates.

[0006] Preferably, the filtering mechanism includes a connecting rod, a connecting frame and a filter screen, one side of the connecting rod is fixedly connected to the connecting frame, two side walls of the filter screen are fixedly connected to a plurality of blocks, connecting holes are provided on the top of the connecting frame and the plurality of blocks, a plurality of square grooves are provided on both sides of the bottom of the connecting frame, and connecting rods that fit into the connecting holes are fixedly connected to the plurality of square grooves.

[0007] Preferably, a square hole is opened on one side of the outer shell, and support slides are fixedly connected to both side walls of the outer shell.

[0008] Preferably, the discharge mechanism comprises an inclined block fixedly connected to the bottom wall of the outer shell, and one side of the outer shell is fixedly connected to a drain pipe.

[0009] Preferably, sealing strips are detachably installed at the multiple side walls where the connecting rod is connected to the square hole.

[0010] Preferably, the plurality of buffer blades are respectively located directly below the plurality of branch pipes b, and the two correspond one to one.

[0011] By means of the above technical solution, the utility model provides a medical wastewater filtering device, which has at least the following beneficial effects:

[0012] 1. The utility model provides a buffer mechanism so that the device can effectively weaken the impact force of falling sewage while keeping the water intake unchanged. The incoming sewage is diverted by the curved connected transverse pipe a, branch pipe a, transverse pipe b, and branch pipe b, thereby initially weakening the impact force of the sewage. The impact force of the diverted sewage before falling into the filter is secondarily weakened by the special-shaped partition plate and multiple buffer blades, which is not easy to cause deformation and jamming of the clamping part between the filter and the device, thereby improving the service life of the device and ensuring the sewage treatment effect of the device.

[0013] 2. The utility model provides a square hole and a supporting slide frame so that the filter mechanism can be easily disassembled and assembled. By pulling the connecting rod, the connecting frame drives the filter screen and the connecting frame to be separated from the outer shell. By separating the connecting frame from the connecting frame, the connecting rod is detached from the connecting hole, so that the filter screen can be easily cleaned and replaced, thereby improving the simplicity of the device.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A medical waste water filtering device provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a medical waste water filtering device includes a shell mechanism 1 as the main body of the device, a discharge mechanism 4 for collecting and treating separated sewage is arranged at the bottom of the shell mechanism 1, a buffer mechanism 2 for buffering the impact force of the sewage is arranged near the top inside the shell mechanism 1, and a filter mechanism 3 for filtering the sewage is arranged below the buffer mechanism 2, and the filter mechanism 3 can be easily separated from the shell mechanism 1, so that the staff can disassemble and replace the filter 303, thereby improving the service life of the device.

[0025] The buffer mechanism 2 includes an inlet pipe 201 fixedly connected to the top of the outer shell 101, a transverse pipe a202 is fixedly connected to the bottom of the inlet pipe 201, and the bottoms of both ends of the transverse pipe a202 are fixedly connected to branch pipes a203, the bottoms of the two branch pipes a203 are fixedly connected to transverse pipes b204, and the bottoms of the transverse pipes b204 are fixedly connected to multiple branch pipes b205. The inner diameters of the inlet pipe 201, the transverse pipe a202, the branch pipes a203, the transverse pipe b204 and the branch pipes b205 are all 300MM, and the amount of water flowing in one hour is between 200 liters and 260 liters. Through multiple curved paths, the impact force of the sewage before the water is discharged is continuously weakened. At the same time, the two side walls of the outer shell 101 are fixedly connected to multiple fixed circular plates 207, and the fixed circular plates 207 relative to each other are fixedly connected to each other. A buffer blade 206 is rotatably connected, and the sewage discharged from the multiple branch pipes b205 is buffered for the second time through the buffer blade 206. The buffer blade 206 rotates automatically when it receives the impact force of the sewage, thereby converting the gravitational potential energy of the sewage part into the kinetic energy of the buffer blade 206, thereby reducing the impact force of the sewage for the second time. A special-shaped partition 208 is fixedly connected between adjacent fixed circular plates 207. The shape of the special-shaped partition 208 is in the shape of a "human", so that the sewage falling from the multiple branch pipes b205 can evenly enter the surface of the filter 303, thereby making the utilization rate of the filter 303 more uniform, and the impact damage received by the filter 303 is greatly reduced by the secondary reduction of the impact force of the sewage, thereby ensuring the sewage treatment effect of the device while improving the service life of the device.

[0026] The filter mechanism 3 includes a connecting rod 301, a connecting frame 305 and a filter screen 303. The material selected for the filter screen 303 is a PVDF ultrafiltration membrane, which has excellent chemical resistance, high temperature resistance, and mechanical strength. The micropore size is usually between 0.1 and 0.02 microns, which can effectively remove suspended matter and colloidal particles in sewage. A connecting frame 302 is fixedly connected to one side of the connecting rod 301, and a plurality of blocks 304 are fixedly connected to the two side walls of the filter screen 303. By aligning the connecting hole at the top of the connecting frame 302 with the connecting holes on the plurality of blocks 304, the connecting rods in the plurality of square grooves 306 at the bottom of the connecting frame 305 are engaged with the connecting holes, thereby fixing the filter screen 303. When the staff needs to adjust the filter screen 3 03 is cleaned or replaced, by pulling the connecting rod 301, the connecting frame 302 drives the filter 303 and the connecting frame 305 to separate from the outer shell 101, and by separating the connecting frame 305 from the connecting frame 302, the connecting rod is disengaged from the connecting hole, thereby completing the removal of the filter 303, thereby improving the simplicity of the device. At the same time, the sealing strips installed on the multiple side walls connected to the square hole 102 by the connecting rod 301 are prevented from leaking the internal sewage when the device is working normally. Since medical waste water contains different chemical pollutants, the sealing strip material can be selected from butyl chloroprene rubber composite material, which has excellent elasticity, weather resistance and chemical corrosion resistance, and can be used for a long time in harsh environments, further improving the service life.

[0027] A square hole 102 is provided on one side of the outer shell 101, and support slides 103 are fixedly connected to the two side walls of the outer shell 101. The filter mechanism 3 is supported and fixed by the support slides 103. The discharge mechanism 4 includes an inclined block 401 fixedly connected to the bottom wall of the outer shell 101. The filtered sewage can be accumulated in the drain pipe 402 by itself through the inclined block 401. The inclination angle of the inclined block 401 is between 20° and 30°, thereby effectively reducing the drainage pressure and improving the drainage efficiency.

[0028] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
