Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a treatment device for medical sewage separation. Background Art
[0002] Medical sewage refers to the wastewater containing pathogenic microorganisms, chemical substances and other harmful components generated in medical institutions such as hospitals, clinics, laboratories, etc. In order to ensure that this sewage meets the discharge standards, effective treatment is required. Extrusion type solid-liquid separation sewage discharge is a commonly used technology, which effectively separates the solid suspended matter in the sewage from the liquid part through mechanical force, thereby reducing the pollution load and improving the effect of subsequent treatment.
[0003] In existing medical sewage treatment equipment, the extrusion type plate filter press, as a common sewage separation method, initially filters and dehydrates the sewage by squeezing between filter plates. Through the filter cloth installed on the filter plates, the liquid is allowed to pass through while blocking solid particles. When the liquid containing suspended solids passes through the filter cloth, the liquid flows out through the small holes of the filter cloth, while the solid particles are intercepted on the surface of the filter cloth, forming a filter cake. Finally, the separation process is completed, with a large filtration area and good dehydration effect. However, during the dehydration process, the filter cloth on the filter plates is easily blocked by impurities and cannot be cleaned in time, resulting in a decline in the filter press effect. Summary of the Invention
[0004] In order to overcome the drawback that during the dehydration process, the filter cloth on the filter plates is easily blocked by impurities and cannot be cleaned in time, resulting in a decline in the filter press effect, the present invention provides a treatment device for medical sewage separation.

Detailed implementation manners
[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0033] Embodiment 1: A treatment device for separating medical sewage, as Figures 1-5 shown, includes a frame 101. A fixed frame 102 is fixedly connected inside the frame 101. A working box 103 is fixedly connected to the upper left side of the fixed frame 102. A cover plate 1041 is rotatably connected to the top of the fixed frame 102. The fixed frame 102 is fixedly installed with first cylinders 104 symmetrically arranged along the front and back of the fixed frame 102. A connecting plate 105 is slidably connected in the upper right part of the fixed frame 102 in the left-right direction. The connecting plate 105 is fixedly connected to the telescopic end of the first cylinder 104. A filter press frame 106 is slidably connected in the right side of the fixed frame 102 in the left-right direction. The filter press frame 106 is slidably connected to the connecting plate 105. The filter press frame 106 is used for filtering medical sewage. A rigid filter screen is arranged on the left side of the filter press frame 106. At least 8 support legs are evenly fixedly installed inside the rigid filter screen for strengthening the support of the filter screen. A cavity is formed between the filter screen of the filter press frame 106 and the support legs for discharging the filtered liquid. A pressure sensor 107 is fixedly installed on the right side of the filter press frame 106. The connecting plate 105 moves leftward to contact the pressure sensor 107. The pressure sensor 107 is electrically connected to the first cylinder 104 through a control module for controlling the reset of the first cylinder 104. A filter frame 108 is slidably connected in the middle left part of the fixed frame 102 for filtering the separated liquid. First guide grooves 110 symmetrically arranged along the front and back of the fixed frame 102 are formed in the fixed frame 102. A cleaning frame 109 is slidably connected in the upper and lower directions on the left side of the filter press frame 106. The cleaning frame 109 penetrates the filter press frame 106 and is slidably connected to the first guide groove 110. A sewage pipe 111 is fixedly connected to the middle of the bottom of the fixed frame 102.
[0034] First, open the cover plate 1041 and pour the medical waste into the working box 103. The medical waste drops onto the filter rack 108. Then, drive the first cylinder 104. The telescopic rod of the first cylinder 104 shortens, driving the connecting plate 105 to move leftward, thereby driving the pressure sensor 107 and the filter press rack 106 to move leftward. The filter press rack 106 squeezes the medical waste. Part of the squeezed sewage directly flows downward through the filter rack 108 into the fixed frame 102, and the other part flows into the cavity of the filter press rack 106 through the rigid filter screen of the filter press rack 106, and then flows downward through the filter rack 108 into the fixed frame 102, and finally is discharged through the sewage pipe 111. In this way, the effect of separating and discharging the sewage in the medical waste is achieved. When the sewage in the medical waste is squeezed dry, the filter press rack 106 is blocked by the solid waste and cannot continue to move leftward. At this time, the telescopic rod of the first cylinder 104 continues to shorten, thereby pulling the connecting plate 105 to move leftward to apply pressure to the pressure sensor 107. The pressure sensor 107 emits an electrical signal, the control module receives the electrical signal, and controls the first cylinder 104 to extend. The telescopic rod of the first cylinder 104 drives the connecting plate 105 to move rightward to reset, thereby driving the filter press rack 106 to move rightward to reset;
[0035] During the above process, when the filter press rack 106 moves leftward, the filter press rack 106 drives the cleaning rack 109 to move leftward along the first guide groove 110. During the leftward movement, under the guiding action of the first guide groove 110, the cleaning rack 109 will move downward along the filter press rack 106 for a certain distance in the initial stage. When the filter press rack 106 moves rightward, the filter press rack 106 drives the cleaning rack 109 to move rightward along the first guide groove 110. During the rightward movement, under the guiding action of the first guide groove 110, the cleaning rack 109 will move upward along the filter press rack 106 for a certain distance to reset in the later stage. During the up and down movement, the cleaning rack 109 will automatically clean the impurities on the filter screen of the filter press rack 106, preventing the fine garbage of the medical waste from blocking the filter holes of the filter press rack 106. To sum up, through the cooperation of the cleaning rack 109 and the first guide groove 110, automatic cleaning of the filter screen is achieved after each filtration, ensuring continuous filtration of the sewage. Through the cavity of the filter press rack 106, when the filter screen is blocked during the sewage squeezing process, there is enough space for the liquid that has completed filtration to be discharged, ensuring the stability of liquid dredging. Through the rigid filter screen provided on the filter press rack 106, high-strength continuous filtration is achieved during the filtration process.
[0036] Such as Figure 2 、 Figure 6 and Figure 7As shown in the figure, it further includes a fixing frame 201. The fixing frame 201 is fixedly connected to the bottom of the fixing frame 102 inside the fixing frame and the filtering frame 108. A first spring 202 is sleeved between the fixing frame 201 and the filtering frame 108. The filtering frame 108 is fixedly connected with engaging teeth 203 symmetrically arranged before and after the filtering frame 108. On both sides of the middle part of the fixing frame 102 before and after, symmetrically arranged second guide grooves 204 are opened. An avoidance groove 207 is opened inside the second guide groove 204. A limiting frame 205 symmetrically distributed before and after the pressure filter frame 106 is slidably connected in the vertical direction at the lower left part of the pressure filter frame 106. The limiting frame 205 is slidably connected with the adjacent avoidance groove 207. The limiting frame 205 is in clamping fit with the adjacent engaging teeth 203. The limiting frame 205 and the engaging teeth 203 are inclined on one side, which is used to pull the filter plate 501 to open. A second spring 206 is fixedly connected between the limiting frame 205 and the pressure filter frame 106.
[0037] In order to ensure that the solid waste after pressure filtration can be discharged from the working box 103 in time, the specific operation is as follows: When the pressure filter frame 106 moves to the left, the pressure filter frame 106 drives the limiting frame 205 and the second spring 206 to move to the left together. The second spring 206 in the stretched state gradually returns to its original position, driving the limiting frame 205 to gradually move downward. When the pressure filter frame 106 disengages from the second guide groove 204 and begins to enter the avoidance groove 207, the second spring 206 just completely returns to its original position, and the limiting frame 205 just catches the engaging teeth 203. During the process of the limiting frame 205 continuing to move to the left along the avoidance groove 207, due to the extrusion between the engaging teeth 203 and the limiting frame 205, the limiting frame 205 intermittently jumps up and down, and the second spring 206 is intermittently compressed and reset.
[0038] When the pressure filter frame 106 moves to the right, the pressure filter frame 106 drives the limiting frame 205 and the second spring 206 to move to the right together. The limiting frame 205 drives the caught engaging teeth 203 to move to the right together, thereby driving the filtering frame 108 to slide to the right along the fixing frame 201 together. The first spring 202 is compressed. In this way, while the pressure filter frame 106 is reset after compressing the medical waste, the filtering frame 108 is automatically pulled open, so that after the sewage is separated, the medical solid waste automatically falls into the rack 101 for collection. And during this process, the limiting frame 205 disengages from the avoidance groove 207 and gradually enters the second guide groove 204. The limiting frame 205 gradually disengages from the engaging teeth 203 upward, and the second spring 206 is gradually stretched. To sum up, through the cooperation of components such as the engaging teeth 203 and the first spring 202, after the pressure filter frame 106 completes the separation of the sewage, the filtering frame 108 is automatically opened, and the solid waste is discharged in time, ensuring the efficiency of pressure filtration.
[0039] Embodiment 2: On the basis of Embodiment 1, as Figure 2 、 Figure 8 and Figure 9As shown in the figure, it further includes a brush 301. The brush 301 is slidably connected to the lower left side of the filter press frame 106 in the up and down direction. The brush 301 is fixedly connected with guide rods 302 symmetrically arranged before and after the brush 301. The guide rods 302 are slidably connected to the adjacent second guide grooves 204.
[0040] In order to ensure the filtering efficiency of the filter frame 108, the specific operation is as follows: When the filter press frame 106 moves left and right, it drives the brush 301 and the guide rods 302 to move left and right synchronously. Affected by the second guide groove 204, at the initial stage when the guide rod 302 moves left along the second guide groove 204, it will move downward along the filter press frame 106, thereby driving the brush 301 to move downward, so that the brush 301 is inserted into the filter frame 108 to clean the filter frame 108. And at the later stage when the guide rod 302 moves right along the second guide groove 204, it will move upward along the filter press frame 106, thereby driving the brush 301 to move upward, so that the brush 301 is separated from the filter frame 108, avoiding the brush 301 from being bent and deformed under the action of the filter frame 108 for a long time when not in use. In summary, through the cooperation of the brush 301 and the second guide groove 204 and other components, the filter frame 108 is automatically cleaned during the movement of the filter press frame 106, ensuring that the filter frame 108 is always in the best filtering state. When the filter press frame 106 returns to the initial position, the brush 301 is automatically lifted, avoiding the brush 301 from being bent for a long time and causing deformation of the brush 301, thus prolonging the service life of the brush 301.
[0041] Embodiment 3: On the basis of Embodiment 2, as Figure 2 and Figure 10 shown in the figure, it further includes a second air cylinder 401. The second air cylinder 401 is fixedly installed on the upper right side of the fixed frame 102. A baffle 402 is fixedly connected to the telescopic rod of the second air cylinder 401. The baffle 402 is slidably connected to the fixed frame 102.
[0042] During the process of filtering medical waste, in order to prevent medical waste from splashing everywhere and causing pollution, the baffle 402 can be used to block the upper part of the fixed frame 102. And when feeding is required, the baffle 402 can be opened by controlling the second air cylinder 401.
[0043] As Figure 2 shown in the figure, it further includes a filter plate 501. The filter plate 501 is fixedly connected to the lower part of the fixed frame 102.
[0044] To prevent the solid waste after pressure filtration from accumulating in the sewage pipe 111 and clogging the sewage pipe 111, when the filter rack 108 is opened and the solid waste after pressure filtration falls onto the filter plate 501, the liquid is discharged into the sewage pipe 111 through the filter plate 501, and the solid waste is guided to the right side of the filter plate 501 by the filter plate 501. In summary, the filter plate 501 blocks and guides the solid waste, preventing the sewage pipe 111 from being clogged and ensuring the smooth discharge of sewage.
[0045] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
