Description

Technical Field

[0001] The invention relates to the technical field of sewage purification, in particular to medical sewage treatment equipment based on potassium monopersulfate disinfection. Background Art

[0002] Wastewater treatment is the process of removing pollutants from urban wastewater, mainly domestic sewage and some industrial wastewater. Physical, chemical and biological processes are used to remove pollutants and produce treated wastewater that is safe for release into the environment. The by-product of sewage treatment is semi-solid waste or slurry, called sewage sludge. Potassium monopersulfate is a strong oxidant that can oxidize many organic and inorganic substances. It is often used in chemical analysis, organic synthesis, environmental governance and other fields. Potassium monopersulfate will produce certain gases and wastes during use. These wastes may contain harmful substances, posing potential risks to the environment and human health.

[0003] The traditional sewage treatment method is to put sewage and sewage treatment agent into corresponding reaction vessels at the same time, and mix and stir them so that the treatment agent can neutralize harmful substances in sewage and flocculate the harmful substances. When the sewage and treatment agent react completely, the flocculated waste is directly filtered through the filter device in the vessel, and the purified water is discharged. Finally, the waste in the reaction vessel is treated. This open waste treatment method will cause harmful substances in the waste to cause harm to the human body, and harmful gases generated by the waste will cause harm to the environment and the human body.

[0022] Compared with the prior art, the present invention provides a medical wastewater treatment device based on potassium monopersulfate disinfection, which has the following beneficial effects:

[0023] 1. The present invention allows the sewage and treatment agent in the inner cavity of the filter tank to react through the operation of the stirring component, and at the same time, waste containing harmful substances is generated. The purified water is discharged through the setting of the sealing component, and at the same time, the waste is concentrated on the stirring chamber and the inner wall of the filter tank. The waste on the inner wall of the filter tank is scraped off through the setting of the collecting component, and at the same time, the waste is concentrated and stored in the inner cavity of the stirring chamber.

[0024] 2. The present invention sets a conversion component so that when the conversion component runs in the forward direction, it only drives the stirring component to run, thereby stirring the sewage in the inner cavity of the filter tank. When the conversion component runs in the reverse direction, it drives the sealing component to run, thereby rotating the filter tank, accelerating the speed at which the treated water in the inner cavity of the filter tank flows outward. At the same time, the centrifugal force generated by the rotation of the filter tank makes the waste stick to the inner wall of the filter tank, thereby facilitating the collection of the waste when the collection component is in operation.

[0025] 3. The present invention performs secondary filtration on a small amount of waste contained in the purified water after filtration by the filter tank through the setting of the filter ring plate, and at the same time scrapes the waste on the inner wall of the purification tank through the setting of the inclined scraper. When the inclined scraper rotates and contacts the scraper plate, the inclined scraper rotates, so that the guide block moves in the inner cavity of the arc groove and squeezes the torsion spring. When the inclined scraper is separated from the scraper plate, the torsion spring resets and resets the inclined scraper, so that the inclined scraper vibrates, and then the waste on the inclined scraper is shaken off. At the same time, when the filter ring plate rotates with the filter tank, the scraper plate scrapes the top of the filter ring plate, so that the waste on the filter ring plate is accumulated on one side of the scraper plate, which is convenient for centralized treatment of the waste.

DETAILED DESCRIPTION

[0037] 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.

[0038] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a medical wastewater treatment equipment based on potassium monopersulfate disinfection.

[0039] See also Figures 1 to 3A medical wastewater treatment device based on potassium monopersulfate disinfection includes a purification tank 1, a filter tank 2 arranged in the inner cavity of the purification tank 1, a stirring component 3 is arranged in the inner cavity of the filter tank 2, a sealing component 4 is arranged on the periphery of the filter tank 2, a conversion component 5 is arranged at the bottom of the filter tank 2, and a collection component 6 is arranged at the top of the filter tank 2.

[0040] A driving device 7 is installed at the bottom of the purification tank 1, and a driving source 61 is powered by the conversion assembly 5;

[0041] A tank cover 8 matching the filter tank 2 is installed on the top of the filter tank 2;

[0042] The stirring assembly 3 includes a stirring chamber 31 and a stirring member 32 disposed in the inner cavity of the stirring chamber 31. The conversion assembly 5 is powered by the stirring chamber 31, so that when the conversion assembly 5 rotates in the forward direction, only the stirring assembly 3 is driven to operate.

[0043] The sealing assembly 4 includes a sealing plate 41, and the conversion assembly 5 and the sealing plate 41 are rotated with power, so that when the conversion assembly 5 rotates in the opposite direction, the sealing plate 41 is driven to move and the filter tank 2 is driven to rotate;

[0044] The collecting assembly 6 includes a driving source 61 . After the filter tank 2 has finished working, the driving source 61 drives the stirring chamber 31 to move upward, and makes the top of the stirring chamber 31 fit with the bottom of the tank cover 8 .

[0045] Specifically, the driving device 7 drives the conversion assembly 5 to rotate in the forward direction, and drives the stirring assembly 3 to operate. At this time, the sealing assembly 4 does not move, thereby driving the stirring chamber 31 and the stirring member 32 in the inner cavity of the filter tank 2 to rotate, and stir the treatment agent and sewage in the inner cavity of the filter tank 2, so that the contact between the treatment agent and the sewage is more sufficient. After the stirring is completed, the driving device 7 drives the conversion assembly 5 to rotate in the reverse direction, and drives the sealing plate 41 to move around the periphery of the filter tank 2. When the sealing plate 41 moves a certain distance and makes the filter tank 2 open, the sealing plate 41 drives the filter tank 2 to rotate, so that The water after the initial purification in the inner cavity of the filter tank 2 is subjected to the centrifugal force and flows into the inner cavity of the purification tank 1, and the waste formed by the reaction between the sewage and the treatment agent is left on the inner wall of the filter tank 2 and the inner cavity of the stirring chamber 31. When most of the sewage in the filter tank 2 is discharged, the collecting component 6 is started, and the stirring chamber 31 is driven to move upward by the driving source 61, and the waste is scraped off the inner wall of the filter tank 2 and stored in the inner cavity of the stirring chamber 31. When the top of the stirring chamber 31 is fitted with the bottom of the tank cover 8, the tank cover 8 is removed, and the waste between the tank cover 8 and the stirring chamber 31 is taken out;

[0046] Through the operation of the stirring component 3, the sewage and the treatment agent in the inner cavity of the filter tank 2 react, and waste containing harmful substances is generated. The purified water is discharged through the setting of the sealing component 4, and the waste is concentrated on the stirring chamber 31 and the inner wall of the filter tank 2. The waste on the inner wall of the filter tank 2 is scraped off through the setting of the collecting component 6, and the waste is concentrated and stored in the inner cavity of the stirring chamber 31. When the stirring chamber 31 moves upward and its top contacts the bottom surface of the tank cover 8, the waste is stored in the inner cavity of the stirring chamber 31. When the tank cover 8 is removed, the stirring chamber 31 is taken out, so that the waste sealed in the inner cavity of the stirring chamber 31 is subjected to the next step of harmless treatment, which solves the problem that the waste generated after the combined treatment of sewage and the treatment agent is left in the corresponding container, the waste contains toxic substances and gases, and open treatment will cause harm to the human body and the environment.

[0047] Further, see Figures 4 to 7 For the above conversion assembly 5, the conversion assembly 5 includes a central tube 51, the inner cavity of the central tube 51 is rotatably connected to a rotating rod 52 through a bearing, the inner wall of the central tube 51 is provided with a plurality of evenly distributed inner grooves 53, the inner cavity of the inner groove 53 is slidably provided with a positive stopper 54, the positive stopper 54 is fixedly installed with a first spring 55 close to the inner cavity of the inner groove 53, one end of the positive stopper 54 away from the first spring 55 is set to an arc surface, the outer periphery of the rotating rod 52 is provided with a plurality of evenly distributed first clamping grooves 56, and the positive stopper 54 is sleeved in the inner cavity of the first clamping groove 56;

[0048] The conversion assembly 5 also includes an outer ring 57, which is sleeved on the outer periphery of the central tube 51. The outer periphery of the central tube 51 is provided with a plurality of evenly distributed grooves 58, and a reverse stopper 59 is slidably provided in the inner cavity of the groove 58. A second spring 510 is fixedly installed on the reverse stopper 59 close to the inner cavity of the groove 58. One end of the reverse stopper 59 away from the second spring 510 is set as an arc surface. A plurality of evenly distributed second grooves 511 are provided on the inner wall of the outer ring 57, and the reverse stopper 59 is sleeved in the inner cavity of the second groove 511.

[0049] The driving device 7 includes a servo motor 71. The central cylinder 51 is arranged at the axis center of the bottom of the inner cavity of the purification tank 1 and is rotatably connected to the purification tank 1 through a bearing. The output end of the servo motor 71 extends to the bottom of the central cylinder 51 and is fixedly connected to the central cylinder 51.

[0050] Specifically, the servo motor 71 drives the center cylinder 51 to rotate in the forward direction. During the rotation process, when the forward stopper 54 rotates to the position of the first slot 56, the first spring 55 recovers its elasticity and drives the forward stopper 54 to move toward the inner cavity of the first slot 56, and makes the forward stopper 54 enter the inner cavity of the first slot 56. At this time, the plane of the forward stopper 54 away from the arc surface contacts the side of the first slot 56, so that when the center cylinder 51 rotates in the forward direction, the rotating rod 52 is driven to rotate, and the stirring assembly 3 is driven to operate. At the same time, the center cylinder 51 During the forward rotation, when the reverse block 59 rotates to the position of the second slot 511, the second spring 510 recovers its elasticity and drives the reverse block 59 to move toward the inner cavity of the second slot 511. At this time, one side of the arc surface of the reverse block 59 contacts the side surface of the second slot 511, so that during the continuous rotation of the center tube 51, the reverse block 59 is squeezed into the inner cavity of the groove 58 again, and the second spring 510 is compressed, so that during the forward rotation of the center tube 51, only the stirring assembly 3 is driven to operate, and the sealing assembly 4 does not move;

[0051] Similarly, when the center tube 51 rotates in the opposite direction, the center tube 51 drives the outer ring 57 to rotate, thereby driving the sealing plate 41 to rotate, and then driving the filter tank 2 to rotate. The center tube 51 rotates in the opposite direction, and the arc surface of the positive stopper 54 contacts the side of the first slot 56. The elastic force generated by the first spring 55 increases the friction between the arc surface of the positive stopper 54 and the side of the first slot 56, which will produce two results. When there is too much waste in the inner cavity of the filter tank 2, the resistance generated by the stirring assembly 3 is greater than the friction between the arc surface of the positive stopper 54 and the side of the first slot 56, and the positive stopper 54 will shrink. It is inserted into the inner cavity of the inner groove 53 and the stirring component 3 is kept stationary. When there is not much waste in the inner cavity of the filter tank 2, the resistance generated by the stirring component 3 is smaller than the friction between the arc surface of the positive stopper 54 and the side of the first slot 56. The positive stopper 54 cannot be received in the inner cavity of the inner groove 53, so that when the central tube 51 rotates in the reverse direction, the stirring component 3 and the sealing component 4 are driven to operate synchronously. Since the function of the sealing component 4 is to rotate and dehydrate the purified water in the inner cavity of the filter tank 2, when the conversion component 5 runs in the reverse direction and drives the sealing component 4 to run, whether the stirring component 3 is running has no effect on the operation of the sealing component 4.

[0052] Further, see Figure 4 For the above stirring assembly 3, a through hole is provided at the axis center of the bottom of the filter tank 2, the outer periphery of the stirring chamber 31 is in contact with the inner wall of the filter tank 2, a circular block 33 is fixedly provided at the bottom of the stirring chamber 31, the circular block 33 is sleeved in the inner cavity of the through hole, a limiting groove 34 is provided at the bottom of the circular block 33, a limiting block 35 is fixedly provided at the top of the rotating rod 52, and the limiting block 35 is sleeved in the inner cavity of the limiting groove 34;

[0053] Specifically, when the conversion assembly 5 runs in the forward direction, the rotating rod 52 is rotated through the socket connection between the limit block 35 at the top of the rotating rod 52 and the limit groove 34 at the bottom of the circular block 33, driving the limit block 35 to rotate, thereby driving the circular block 33 and the stirring chamber 31 on the top of the circular block 33 to rotate, and driving the stirring element 32 in the inner cavity of the stirring chamber 31 to rotate, thereby stirring the sewage in the inner cavity of the filter tank 2.

[0054] Further, see Figure 3 For the above-mentioned collecting assembly 6, the collecting assembly 6 also includes a telescopic rod 62, and the driving source 61 includes a servo cylinder 611. The servo cylinder 611 is fixedly installed at the top axis of the tank cover 8. One end of the telescopic rod 62 is fixedly installed at the bottom axis of the tank cover 8. The output end of the servo cylinder 611 is fixedly connected to the telescopic rod 62. The other end of the telescopic rod 62 is installed at the top axis of the stirring member 32 and is rotatably connected to the stirring member 32 through a bearing. A sealing ring 63 is fixedly installed at the bottom edge of the tank cover 8. The outer side surface of the sealing ring 63 and the inner side surface of the stirring chamber 31 are provided with mutually matching inclined surfaces;

[0055] Specifically, the servo cylinder 611 drives the telescopic rod 62 to contract, thereby driving the stirring chamber 31 to move upward. By setting the outer wall of the stirring chamber 31 to fit the inner wall of the filter tank 2 and the inner side surface of the stirring chamber 31 to be an inclined surface, the top of the stirring chamber 31 scrapes off the waste on the inner wall of the filter tank 2. When the stirring chamber 31 rises to the top of the inner cavity of the filter tank 2 and contacts the bottom of the tank cover 8, the outer side surface of the sealing ring 63 and the inclined surface of the inner side surface of the stirring chamber 31 match each other, thereby sealing the stirring chamber 31.

[0056] Further, see Figure 3 For the above-mentioned sealing assembly 4, filter holes 44 are provided on the periphery of the filter tank 2, and the filter holes 44 are evenly distributed on the periphery of the filter tank 2 in a regional manner. Multiple sets of guide grooves 42 are provided on the upper and lower sides of the periphery of the filter tank 2. The sealing plate 41 slides with the filter tank 2 through the guide grooves 42, so that the filter holes 44 are sealed when the sealing plate 41 moves toward one end of the guide groove 42, and the filter holes 44 are in a released state when the sealing plate 41 moves toward the other end of the guide groove 42. A right-angle plate 43 is fixedly provided at the bottom of the sealing plate 41, and the right-angle plate 43 is fixedly connected to the outer side of the outer ring 57 at one end away from the sealing plate 41;

[0057] Specifically, the friction force between the sealing plate 41 and the filter tank 2 is greater than the friction force between the arc surface of the reverse stopper 59 and the second slot 511, so that when the conversion assembly 5 rotates forward, the central tube 51 drives the rotating rod 52 to rotate and drives the stirring assembly 3 to operate. At this time, the arc surface of the reverse stopper 59 contacts the side of the second slot 511, and the reverse stopper 59 is received in the inner cavity of the groove 58, so that the sealing assembly 4 is immobile. When the conversion assembly 5 operates in the reverse direction, the central tube 51 rotates and drives the outer ring 57 to rotate, so that the sealing plate 41 moves away from the filter hole 44, so that the filter hole 44 is exposed. When the sealing plate 41 moves to the other end of the guide groove 42, the sealing plate 41 rotates and drives the filter tank 2 to rotate, so that the purified water in the inner cavity of the filter tank 2 generates centrifugal force, and the water in the inner cavity of the filter tank 2 flows into the purification tank 1 through the filter hole 44, and the waste generated by the reaction adheres to the inner wall of the filter tank 2.

[0058] Further, see Figures 8 to 10 For the above-mentioned purification tank 1, a plurality of scraping components 9 are arranged on the periphery of the filter tank 2, and the scraping components 9 include an inclined scraper 91, one side of the inclined scraper 91 is in contact with the inner wall of the purification tank 1, and a connecting plate 92 is fixedly installed on the other side of the inclined scraper 91, and a fixed shaft 93 is fixedly installed on one end of the connecting plate 92. The connecting plate 92 is rotatably connected to the sealing plate 41 through the fixed shaft 93, and a torsion spring 94 is installed at the junction of the fixed shaft 93 and the sealing plate 41. Guide blocks 95 are fixedly installed at both ends of one side of the connecting plate 92, and arc grooves 96 are opened at both ends of one side of the sealing plate 41, and the sliding rod of the guide block 95 is arranged in the inner cavity of the arc groove 96;

[0059] A filter ring plate 97 is fixedly installed on the outer periphery of the sealing plate 41, and the outer periphery of the filter ring plate 97 is in contact with the inner wall of the purification tank 1. A scraper plate 98 is fixedly installed on the inner wall of the purification tank 1, and the bottom of the scraper plate 98 is in contact with the top of the filter ring plate 97. The top of the scraper plate 98 is formed into an arc surface, so that when the inclined scraper plate 91 contacts the scraper plate 98, the inclined scraper plate 91 is driven to vibrate;

[0060] Specifically, when the filter tank 2 rotates, the inclined scraper 91 is driven to rotate synchronously and scrape the inner wall of the purification tank 1. When the inclined scraper 91 rotates, the top of the inclined scraper 91 tends to the forward direction of the inclined scraper 91, so that when the inclined scraper 91 scrapes the inner wall of the purification tank 1, part of the waste on the inner wall of the purification tank 1 flows downward along with the inclined scraper 91, thereby cleaning the inner wall of the purification tank 1. When the inclined scraper 91 rotates and contacts the scraper plate 98, the inclined scraper 91 rotates, so that the guide block 95 moves in the inner cavity of the arc groove 96 and squeezes the torsion spring 94. When the inclined scraper 91 is separated from the scraper plate 98, the torsion spring 94 is reset and the inclined scraper 91 is reset, so that the inclined scraper 91 vibrates, and then the waste on the inclined scraper 91 is shaken off. At the same time, when the filter ring plate 97 rotates with the filter tank 2, the scraper plate 98 scrapes the top of the filter ring plate 97, so that the waste on the filter ring plate 97 is accumulated on one side of the scraper plate 98.

[0061] Further, see Figure 1 For the above-mentioned purification tank and filter tank, a feed pipe 10 is fixedly installed on the top of the tank cover 8, a discharge pipe 11 is fixedly installed on the bottom of the purification tank 1, a sealed door 12 is opened on the periphery of the purification tank 1, and a scraper plate 98 is installed on the side close to the sealed door 12;

[0062] Specifically, switch valves are installed on the outer periphery of the discharge pipe 11 and the feed pipe 10 to control the inflow and outflow of sewage and purified water. At the same time, the sealing chamber door 12 is installed on one side of the scraper plate 98. When the device is completed, the waste on the top of the filter ring plate 97 is accumulated on one side of the scraper plate 98, and the waste is processed by opening the sealing chamber door 12.

[0063] Working principle: When in use, the servo cylinder 611 drives the telescopic rod 62 to extend, and the stirring chamber 31 is placed into the inner cavity of the filter tank 2, and the limiting groove 34 at the bottom of the circular block 33 is overlapped with the limiting block 35 at the top of the rotating rod 52, and then the sewage treatment agent is poured into the filter tank 2, so that the sewage treatment agent is located in the inner cavity of the stirring chamber 31, and by controlling the length of the telescopic rod 62, the tank cover 8 is overlapped with the filter tank 2, and then the sewage is discharged into the inner cavity of the filter tank 2 through the feeding pipe 10;

[0064] After the preparation work is completed, the servo motor 71 drives the center tube 51 to rotate forward. During the rotation process, when the forward stopper 54 rotates to the position of the first slot 56, the first spring 55 restores its elasticity and drives the forward stopper 54 to move toward the inner cavity of the first slot 56, and makes the forward stopper 54 enter the inner cavity of the first slot 56. At this time, the plane of the forward stopper 54 away from the arc surface contacts the side of the first slot 56, so that when the center tube 51 rotates forward, the rotating rod 52 is driven to rotate, and the limiting block 35 at the top of the rotating rod 52 is connected with the limiting slot 34 at the bottom of the circular block 33, so that the rotating rod 52 is rotated, and the limiting block 35 is driven to rotate, thereby driving the circular block 33 and the stirring chamber 31 at the top of the circular block 33 to rotate, and driving the stirring member 32 in the inner cavity of the stirring chamber 31 to rotate, so as to stir the sewage in the inner cavity of the filter tank 2;

[0065] At the same time, during the forward rotation of the center cylinder 51, when the reverse stopper 59 rotates to the position of the second slot 511, the second spring 510 recovers its elasticity and drives the reverse stopper 59 to move toward the inner cavity of the second slot 511. At this time, one side of the arc surface of the reverse stopper 59 contacts the side surface of the second slot 511, so that during the continuous rotation of the center cylinder 51, since the friction between the sealing plate 41 and the filter tank 2 is greater than the friction between the arc surface of the reverse stopper 59 and the second slot 511, the reverse stopper 59 is squeezed into the inner cavity of the groove 58 again, and the second spring 510 is compressed, so that during the forward rotation of the center cylinder 51, only the stirring assembly 3 is driven to operate, and the sealing assembly 4 does not move;

[0066] When the stirring assembly 3 is finished working, the servo motor 71 rotates in the reverse direction, the central cylinder 51 rotates and drives the outer ring 57 to rotate, so that the sealing plate 41 moves away from the filter hole 44, so that the filter hole 44 is exposed. When the sealing plate 41 moves to the other end of the guide groove 42, the sealing plate 41 rotates and drives the filter tank 2 to rotate, so that the purified water in the inner cavity of the filter tank 2 generates centrifugal force, and the water in the inner cavity of the filter tank 2 flows into the purification tank 1 through the filter hole 44, and the waste generated by the reaction is attached to the inner wall of the filter tank 2;

[0067] When the filter tank 2 rotates, the inclined scraper 91 is driven to rotate synchronously and scrape the inner wall of the purification tank 1. When the inclined scraper 91 rotates, the top of the inclined scraper 91 tends to the forward direction of the inclined scraper 91, so that when the inclined scraper 91 scrapes the inner wall of the purification tank 1, part of the waste on the inner wall of the purification tank 1 flows downward along with the inclined scraper 91, thereby cleaning the inner wall of the purification tank 1. When the inclined scraper 91 rotates and contacts the scraper plate 98, the inclined scraper 91 rotates, so that the guide block 95 moves in the inner cavity of the arc groove 96 and squeezes the torsion spring 94. When the inclined scraper 91 is separated from the scraper plate 98, the torsion spring 94 is reset and the inclined scraper 91 is reset, so that the inclined scraper 91 vibrates, and then the waste on the inclined scraper 91 is shaken off. At the same time, when the filter ring plate 97 rotates with the filter tank 2, the scraper plate 98 scrapes the top of the filter ring plate 97, so that the waste on the filter ring plate 97 is accumulated on one side of the scraper plate 98;

[0068] After the water in the inner cavity of the filter tank 2 is drained, the servo cylinder 611 drives the telescopic rod 62 to contract, thereby driving the stirring chamber 31 to move upward. The outer wall of the stirring chamber 31 is arranged to fit the inner wall of the filter tank 2, and the inner side surface of the stirring chamber 31 is arranged to be an inclined surface, so that the top of the stirring chamber 31 scrapes the waste on the inner wall of the filter tank 2. When the stirring chamber 31 rises to the top of the inner cavity of the filter tank 2 and contacts the bottom of the tank cover 8, the outer side surface of the sealing ring 63 and the inclined surface of the inner side surface of the stirring chamber 31 are matched with each other, so that the stirring chamber 31 is sealed, and the waste generated in the sewage treatment process is sealed in the inner cavity of the stirring chamber 31.

[0069] Finally, the can cover 8 is taken out to take out the sealed waste, and the small amount of waste accumulated on one side of the scraper plate 98 is processed by opening the sealed bin door 12.
