Referring to fig. 1 to 7, the present invention provides a catalytic reaction system for a water purifying agent, comprising a tank body 1 for accommodating a water body to be treated, wherein the tank body 1 is provided with a tank cover 2 and a pressurizing mechanism 3 for injecting air into the tank;
the pressurizing mechanism 3 comprises a hollow pressurizing column 31 vertically arranged in the center of the barrel body 1, and an opening 32 is formed in the upper end of the hollow pressurizing column 31; the lower end of the hollow pressurizing column 31 is provided with an air outlet 33, the air outlet 33 is hinged with a first valve plate 34, the first valve plate 34 is used for controlling the opening and closing of the air outlet 33, and the opening of the first valve plate 34 is outward; a pressurizing plate 35 is vertically and slidably mounted inside the hollow pressurizing column 31, an air inlet 36 is formed in the pressurizing plate 35, a second valve plate 37 is hinged to the lower end of the pressurizing plate 35, and the second valve plate 37 is used for controlling the opening and closing of the air inlet 36; the opening of the second valve plate 37 is downward; a rotating disc 38 is arranged at the opening 32, the rotating disc 38 is rotatably mounted on the barrel wall through a first rotating shaft 39, a driving column 40 is eccentrically and fixedly arranged on the end surface of the rotating disc 38, the driving column 40 is hinged with the pressurizing plate 35 through a driving rod 41, and the driving rod 41 is used for driving the pressurizing plate 35 to vertically reciprocate in the hollow pressurizing column 31;
the barrel cover 2 is further provided with a speed regulating mechanism 5 connected with the pressurizing mechanism 3, and the speed regulating mechanism 5 regulates the rotating speed of the first rotating shaft 39 according to the air pressure in the barrel body 1.
As shown in figure 1, when in use, a water body to be treated with a specified volume is firstly led into a barrel body 1, and a specified biological purifying agent is put into the barrel, wherein the biological purifying agent needs oxygen to participate in reaction when purifying the water body, and in order to improve the catalytic efficiency, the oxygen concentration in the water body needs to be improved, and oxygen is supplied to the water body. As shown in fig. 2, the first rotating shaft 39 is driven to rotate, the first rotating shaft 39 rotates to drive the rotating disc 38 to rotate, the rotating disc 38 rotates to drive the driving column 40 eccentrically and fixedly mounted on the rotating disc 38 to rotate, and the driving column 40 drives the pressurizing plate 35 to vertically reciprocate in the hollow pressurizing column 31 through the driving rod 41. As shown in fig. 4, when the pressurizing plate 35 moves vertically upward under the driving of the driving rod 41, the space below the pressurizing plate 35 in the hollow pressurizing column 31 increases, the air pressure thereof decreases, the second valve plate 37 is driven by the external air under the extrusion of the atmospheric pressure to open the air inlet 36 downward, and the external air enters the hollow pressurizing column 31; as shown in fig. 5, when the pressurizing plate 35 moves vertically downward under the driving of the driving rod 41, the space below the pressurizing plate 35 in the hollow pressurizing column 31 decreases, the air pressure thereof increases, but because the opening of the second valve plate 37 is downward, the second valve plate 37 closes the air inlet 36, the air in the hollow pressurizing column 31 moves toward the air outlet 33 under the pressing of the pressurizing plate 35, the first valve plate 34 at the air outlet 33 opens against the water pressure under the action of the air pressure, and the air enters the water body in the tub 1 and diffuses in the water body in the form of bubbles; when the air is exhausted, the pressurizing plate 35 moves upward again, and the first valve plate 34 closes the exhaust port 33 under the action of the water pressure, and the air is sucked again through the air inlet 36, so that the circulation is repeated, and oxygen is continuously supplied to the water in the barrel body 1. Because of the low solubility of oxygen in water, oxygen needs to be continuously supplied to the water body. As shown in figure 2, the invention arranges a closed barrel cover 2 in the barrel body 1, thus the gas pressure in the barrel body 1 is continuously increased when oxygen is continuously supplied, under the condition of increased pressure, the oxygen solubility in water is also increased, the oxygen concentration in the water body is increased, and the reaction efficiency of the biological purifying agent is improved. At first, the oxygen content in the water body in the barrel body 1 is low, and oxygen needs to be supplied to the water body quickly, so that the rotating speed of the first rotating shaft 39 is high, and the purpose of supplying oxygen quickly is achieved. However, after a period of reaction, the biological purifying agent begins to generate flocculent precipitates continuously, and bubbles in the water body generated continuously due to continuous oxygen supply influence the generation of the flocculent precipitates and influence the purifying efficiency of the biological purifying agent. Therefore, the invention is also provided with a speed regulating mechanism 5, and the speed regulating mechanism 5 regulates the rotating speed of the first rotating shaft 39 according to the air pressure in the barrel body 1. When the air pressure is higher after a period of oxygen supply, the oxygen supply speed is reduced by reducing the rotating speed of the first rotating shaft 39 while the high oxygen solubility in the water body is maintained, the influence of bubbles on the flocculation precipitation in the water body during oxygen supply is reduced, the generation of flocculent precipitation is assisted, and the purification efficiency of the biological purifying agent is improved. The invention can continuously supply oxygen to the closed barrel body 1, and can enhance the air pressure in the barrel body 1 while directly supplying oxygen, improve the solubility of the oxygen in the water body, improve the oxygen concentration in the container and improve the purification efficiency; the invention can also adjust the oxygen supply speed according to the air pressure in the barrel body 1, and can quickly supply oxygen when the initial air pressure is lower, thereby improving the aerobic reaction efficiency of the biological purifying agent; when the air pressure is higher after a period of time, the oxygen supply speed is reduced while the high oxygen solubility in the water body is maintained, the influence of bubbles on the flocculation precipitation in the water body during oxygen supply is reduced, and the generation of flocculent precipitates is assisted.
As a further scheme of the invention, the barrel cover 2 is vertically and slidably mounted in the barrel body 1, and a limiting plate 68 for limiting the upper and lower limit strokes of the barrel cover 2 is fixedly arranged on the inner wall of the barrel body 1; the speed regulating mechanism 5 comprises a driving motor 51 arranged on the barrel cover 2, and an arc driving disc 53 is fixedly arranged on a driving shaft 52 of the driving motor 51; a friction disc 54 is keyed on the first rotating shaft 39, and the arc driving disc 53 is in friction transmission connection with the friction disc 54; a first spring 55 is disposed between the friction disc 54 and the rotating disc 38.
As shown in fig. 2 and 3, the speed regulating mechanism 5 of the present invention has a specific speed regulating process, in which the driving shaft 52 of the driving motor 51 rotates, and the first rotating shaft 39 is driven to rotate through the transmission of the arc-shaped driving disc 53 and the friction disc 54, so that the pressurizing mechanism 3 continuously supplies oxygen to the water body in the tub 1. The oxygen supply rate at the beginning is high, and the rotation speed of the first rotating shaft 39 is high. The air pressure in the barrel body 1 is continuously increased along with the oxygen supply, at the moment, the barrel cover 2 vertically and slidably installed in the barrel body 1 vertically moves upwards under the action of the air pressure, and because the driving motor 51 of the invention is installed on the barrel cover 2, the driving motor 51 moves upwards along with the barrel cover 2, and the driving shaft 52 and the arc driving disk 53 on the driving motor 51 also move upwards along with the barrel cover 2, so that the friction transmission position of the arc driving disk 53 and the friction disk 54 is changed. The friction transmission position of the arc driving disk 53 and the friction disk 54 is originally located at the outer periphery of the arc driving disk 53, the transmission ratio is large, and when the arc driving disk 53 moves vertically upwards, the friction transmission position of the arc driving disk 53 and the friction disk 54 moves towards the inner periphery of the arc driving disk 53, and the transmission ratio is reduced. The specific principle is that the angular velocity is constant, and the linear velocity is inversely proportional to the radius. Along with the enhancement of the air pressure in the barrel body 1, the oxygen solubility in the water body is increased, the oxygen concentration is increased, and the purification efficiency of the biological purifying agent is improved; meanwhile, the barrel cover 2 gradually moves upwards, the friction transmission position of the arc driving disk 53 and the friction disk 54 moves upwards, the transmission ratio is reduced, the rotating speed of the first rotating shaft 39 is reduced, the reciprocating frequency of the pressurizing plate is reduced, the oxygen supply speed is reduced, bubbles generated due to oxygen supply are reduced, the influence of the bubbles on flocculation and precipitation in the water body during oxygen supply is reduced, the generation of flocculent precipitates is assisted, and the purification efficiency of the biological purifying agent is improved. The limiting plate 68 is arranged to limit the upper and lower limit strokes of the barrel cover 2 and prevent the barrel cover 2 from separating from the barrel body 1.
As a further scheme of the invention, the hollow pressurizing column 31 is rotatably installed on the bottom plate of the barrel body 1, and a threaded section 61 is formed in the hollow pressurizing column 31; a connecting rod 62 is fixedly installed on the pressurizing plate 35, and the connecting rod 62 is hinged with the ball head of the driving rod 41; a driving ring 63 is fixedly mounted on the connecting rod 62, and the driving ring 63 is in threaded connection with the threaded section 61.
As shown in fig. 2 and 4, in the present invention, a connecting rod 62 is fixedly mounted on the pressure plate 35, and the pressure plate 35 is hinged to the driving rod 41 through the connecting rod 62. When the pressurizing plate 35 is vertically reciprocated by the driving rod 41, the connecting rod 62 is vertically reciprocated together with the pressurizing plate 35, and the driving ring 63 fixedly mounted on the connecting rod 62 is also vertically reciprocated inside the hollow pressurizing column 31. Since the driving ring 63 is threadedly coupled to the threaded section 61 on the inner wall of the hollow pressurizing column 31, the driving ring 63 drives the hollow pressurizing column 31 to rotate repeatedly in the barrel body 1 while vertically reciprocating. Therefore, when the exhaust port 33 exhausts, the bubbles are thrown out from the exhaust port 33 under the action of centrifugal force, the moving range of the bubbles is expanded, the contact path of the water body and the bubbles is increased, and the purification efficiency of the biological purifying agent is improved.
In a further aspect of the present invention, a rotating ring 64 is fixedly mounted on the outer circumference of the hollow pressurizing column 31, and stirring fans 65 are disposed at regular intervals in the circumferential direction of the rotating ring 64.
As shown in fig. 2, the purpose of this arrangement is to utilize the repeated rotation of the hollow pressurizing column 31 to drive the rotating ring 64 to rotate repeatedly, and further drive the stirring fan 65 to rotate back and forth to stir the water body, so that the biological purifying agent in the water body can be fully contacted with water and oxygen, and the purifying efficiency of the biological purifying agent is improved.
As a further scheme of the invention, a vent hole 66 is formed on the barrel cover 2, and a spring-type pressure relief valve 67 is installed at the vent hole 66.
As shown in FIG. 2, after the barrel cover 2 of the present invention is moved to the upper limit position, the first rotating shaft 39 rotates slowly, and the pressurizing mechanism 3 supplies oxygen slowly, so that the air pressure in the barrel body 1 still increases slowly, and at this time, the spring-type pressure relief valve 67 maintains the air pressure in the barrel body 1 in a high state, but does not increase infinitely. As the aerobic reaction of the biological purifying agent consumes oxygen to generate carbon dioxide, the air pressure in the barrel body 1 is kept unchanged along with the progress of time, and when the oxygen content in the barrel body 1 is reduced, the spring type pressure release valve 67 can also discharge the gas with low oxygen concentration in the barrel body 1 and replace the gas with high oxygen concentration newly entering the exhaust port 33, so that the purifying efficiency of the biological purifying agent is improved.
As a further scheme of the invention, the barrel body 1 is provided with a water inlet hole 71 and a water outlet hole 72, and a filter screen 73 is arranged at the position of the water outlet hole 72. As shown in fig. 2 and 6, the invention enters water from the water inlet 71 and discharges water from the water discharge hole 72, and the sediment is filtered out by the filter screen 73 during the water discharge, so as to obtain the purified water body.
As a further aspect of the present invention, a torsion spring 74 is disposed at the hinge joint of the first valve plate 34 and the exhaust port 33. As shown in fig. 5, the purpose of this arrangement is to further ensure that the first valve can close the air outlet 33 quickly during air suction, so as to prevent the water in the barrel 1 from entering the hollow pressurizing column 31 from the air outlet 33.
The invention also provides a catalytic reaction method of the water purifying agent, which comprises the reaction system and mainly comprises the following steps:
s1: introducing a water body to be treated with a specified volume into the barrel body 1, and adding a specified biological purifying agent into the barrel, wherein the biological purifying agent needs oxygen to participate in a reaction when purifying the water body, and the oxygen concentration in the water body needs to be increased in order to improve the catalytic efficiency;
s2: the driving motor 51 is started, the pressurizing plate 35 continuously and rapidly reciprocates to rapidly extrude outside air into the barrel through the hollow pressurizing column 31 at the beginning, the air enters from the bottom of the barrel body 1 and is diffused into the water body, the pressure in the barrel body 1 is continuously increased along with the continuous reciprocating motion of the pressurizing plate 35, the solubility of oxygen in the water body is improved, and the catalytic efficiency is improved;
s3: flocculent precipitates are generated in a water body after reacting for a period of time, external bubbles continuously entering water influence the flocculent precipitates, so that the reciprocating efficiency of the pressurizing plate 35 needs to be reduced, and along with the continuous increase of the pressure in the barrel body 1, gas in the barrel can extrude the barrel cover 2 to vertically move upwards, so that the rotating speed of the first rotating shaft 39 is reduced by the speed regulating mechanism 5, the reciprocating efficiency of the pressurizing plate 35 is further reduced, and the flocculent precipitates are generated in an auxiliary manner;
