Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a treatment device for separating medical sewage. Background Art

[0002] Medical wastewater refers to wastewater containing pathogenic microorganisms, chemicals and other harmful components generated in medical institutions such as hospitals, clinics, and laboratories. In order to ensure that these wastewaters meet the discharge standards, effective treatment is required. Extrusion solid-liquid separation sewage discharge is a commonly used technology that effectively separates the solid suspended matter from the liquid part in the sewage through mechanical force, thereby reducing the pollution load and improving the effect of subsequent treatment.

[0003] Among the existing medical wastewater treatment equipment, the extrusion plate filter press is a common way to separate wastewater. The filter plates are squeezed against each other to perform preliminary filtration and dehydration of the wastewater. The filter cloth installed on the filter plate allows the liquid to pass through while blocking the 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 trapped on the surface of the filter cloth to form a filter cake. Finally, the separation process is completed, the filtration area is large, and the dehydration effect is good. However, during the dehydration process, the filter cloth on the filter plate is easily clogged by impurities and cannot be cleaned in time, resulting in a decrease in the filtration effect.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: A treatment device for separating medical wastewater, such as Figure 1-Figure 5 As shown, it 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, a first cylinder 104 symmetrically arranged along the front and rear of the fixed frame 102 is fixedly installed on the fixed frame 102, a connecting plate 105 is slidably connected to the right side of the upper part of the fixed frame 102 along the left and right directions, the connecting plate 105 is fixedly connected to the telescopic end of the first cylinder 104, a filter press frame 106 is slidably connected to the right side of the fixed frame 102 along the left and right directions, 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, and at least 8 supporting legs are evenly and fixedly installed on the inner side of the rigid filter screen for strengthening the process. The filter screen is supported, and a cavity is formed between the filter screen and the supporting legs of the filter press frame 106, which is used to discharge the filtered liquid. A pressure sensor 107 is fixedly installed on the right side of the filter press frame 106, and the connecting plate 105 moves to the left to contact the pressure sensor 107. The pressure sensor 107 is electrically connected to the first cylinder 104 through the control module, which is used to control the reset of the first cylinder 104. A filter frame 108 is slidably connected to the left side of the middle part of the fixed frame 102, which is used to filter the separated liquid. A first guide groove 110 symmetrically arranged along the front and back of the fixed frame 102 is opened in the fixed frame 102, and a cleaning frame 109 is slidably connected to the left side of the filter press frame 106 in the up and down directions. The cleaning frame 109 penetrates the filter press frame 106 and is slidably connected to the first guide groove 110, and a sewage pipe 111 is fixedly connected to the middle of the bottom of the fixed frame 102.

[0034] First, open the cover 1041, pour the medical waste into the working box 103, and the medical waste falls onto the filter frame 108. Then, drive the first cylinder 104, shorten the telescopic rod of the first cylinder 104, drive the connecting plate 105 to move leftward, thereby drive the pressure sensor 107 and the filter press frame 106 to move leftward, and the filter press frame 106 squeezes the medical waste. A part of the squeezed sewage flows directly downward into the fixed frame 102 through the filter frame 108, and the other part flows into the cavity of the filter press frame 106 through the rigid filter screen of the filter press frame 106, and then flows downward through the filter frame 108 into the fixed frame 102. The medical waste is finally discharged through the sewage pipe 111, so that the sewage in the medical waste is separated and discharged. When the sewage in the medical waste is squeezed out, the filter press frame 106 is blocked by the solid waste and cannot continue to move to the left. At this time, the telescopic rod of the first cylinder 104 continues to shorten, thereby pulling the connecting plate 105 to the left to press the pressure sensor 107. The pressure sensor 107 sends an electrical signal, and 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 and reset, thereby driving the filter press frame 106 to move rightward and reset; In the above process, when the filter press frame 106 moves to the left, the filter press frame 106 drives the cleaning frame 109 to move to the left along the first guide groove 110. In the process of moving to the left, the cleaning frame 109 will move downward along the filter press frame 106 for a distance at the initial stage under the guidance of the first guide groove 110. When the filter press frame 106 moves to the right, the filter press frame 106 drives the cleaning frame 109 to move to the right along the first guide groove 110. In the process of moving to the right, the cleaning frame 109 will move upward along the filter press frame 106 for a distance to reset at the later stage under the guidance of the first guide groove 110. In the process of moving up and down, the cleaning frame 109 9 will automatically clean the impurities on the filter screen of the filter press frame 106 to prevent the fine garbage of medical waste from clogging the filter holes of the filter press frame 106. In summary, through the cooperation of the cleaning frame 109 and the first guide groove 110, the filter screen can be automatically cleaned after each filtration is completed, thereby ensuring the continuous filtration of sewage. Through the cavity of the filter press frame 106, when the filter screen is blocked during the process of squeezing sewage, there is enough space to discharge the liquid after the filtration is completed, thereby ensuring the stability of liquid dredging. Through the rigid filter screen set on the filter press frame 106, high-intensity continuous filtration is achieved during the filtration process.

[0035] like Figure 2 , Figure 6 and Figure 7As shown, it also includes a fixing frame 201, which is fixedly connected to the bottom of the fixing frame 102 and the filter frame 108, a first spring 202 is sleeved between the fixing frame 201 and the filter frame 108, the filter frame 108 is fixedly connected with a latching tooth 203 symmetrically arranged along the front and back of the filter frame 108, and a second guide groove 204 symmetrically arranged is opened on both sides of the front and back of the middle part of the fixing frame 102, and an avoidance groove 207 is opened inside the second guide groove 204. A limiting frame 205 symmetrically distributed along the front and back of the filter frame 106 is slidably connected to the lower left side of the filter press frame 106 along the up and down direction, and the limiting frame 205 is slidably connected to the adjacent avoidance groove 207, and the limiting frame 205 is engaged with the adjacent latching tooth 203. The limiting frame 205 and the latching tooth 203 are unilaterally inclined, which are used to pull the filter plate 501 to open, and a second spring 206 is fixedly connected between the limiting frame 205 and the filter press frame 106.

[0036] In order to ensure that the solid waste after the filtration is completed can be discharged from the working box 103 in time, the specific operation is as follows: when the filter press frame 106 moves to the left, the filter press frame 106 drives the limit frame 205 and the second spring 206 to move to the left together, and the second spring 206 in the stretched state gradually resets, driving the limit frame 205 to move gradually downward. When the filter press frame 106 breaks away from the second guide groove 204 and begins to enter the avoidance groove 207, the second spring 206 is just completely reset, and the limit frame 205 just catches the tooth 203. In the process of the limit frame 205 continuing to move to the left along the avoidance groove 207, the squeezing effect of the tooth 203 and the limit frame 205 causes the limit frame 205 to jump up and down intermittently, and the second spring 206 is intermittently compressed and reset.

[0037] When the filter press frame 106 moves to the right, the filter press frame 106 drives the limiting frame 205 and the second spring 206 to move to the right together, and the limiting frame 205 drives the stuck latch 203 to move to the right together, thereby driving the filter frame 108 to slide to the right along the fixed frame 201, and the first spring 202 is compressed. In this way, when the filter press frame 106 is reset after compressing the medical waste, the filter frame 108 is automatically pulled open, so that after the sewage is separated, the medical solid waste automatically falls into the frame 101 for collection, and in 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 latch 203 upwards, and the second spring 206 is gradually stretched. In summary, through the cooperation of the latch 203 and the first spring 202 and other components, the filter press frame 106 automatically opens the filter frame 108 after completing the separation of the sewage, and the solid waste is discharged in time, thereby ensuring the efficiency of the filter press.

[0038] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 8 and Fig. 9As shown, it also includes a brush 301, which is slidably connected to the lower left side of the filter press frame 106 along the up and down directions. The brush 301 is fixedly connected to a guide rod 302 symmetrically arranged along the front and back of the brush 301, and the guide rod 302 is slidably connected to the adjacent second guide groove 204.

[0039] In order to ensure the filtration efficiency of the filter frame 108, the specific operation is as follows: when the filter frame 106 moves left and right, it drives the brush 301 and the guide rod 302 to move left and right synchronously. Affected by the second guide groove 204, the guide rod 302 moves leftward along the second guide groove 204 in the initial stage of moving to the left, and moves downward along the filter 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 the guide rod 302 moves rightward along the second guide groove 204 in the later stage of moving upward along the filter frame 106, thereby driving the brush 301 to move downward. The brush 301 moves upward, so that the brush 301 is separated from the filter frame 108, thereby preventing the brush 301 from being bent and deformed by 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 to prevent the brush 301 from bending for a long time, causing the brush 301 to deform, thereby extending the service life of the brush 301.

[0040] Embodiment 3: Based on embodiment 2, Figure 2 and Fig.10 As shown, a second cylinder 401 is also included. The second 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 cylinder 401. The baffle 402 is slidably connected to the fixed frame 102.

[0041] In the process of filtering the medical waste, in order to prevent the medical waste from splashing and causing pollution, the baffle 402 can be used to block the top of the fixed frame 102. When feeding is required, the baffle 402 can be opened by controlling the second cylinder 401.

[0042] like Figure 2 As shown, a filter plate 501 is also included, and the filter plate 501 is fixedly connected to the lower part of the fixing frame 102.

[0043] In order to prevent the solid waste after filtration from accumulating in the sewage pipe 111 and clogging the sewage pipe 111, when the filter rack 108 is opened, the solid waste after filtration falls into the filter plate 501, and 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 solid waste is blocked and guided by the filter plate 501, which prevents the sewage pipe 111 from being blocked, thereby ensuring that the sewage can be discharged smoothly.

[0044] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
