DETAILED DESCRIPTION

[0018] 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.

[0019] Example 1: Figure 1-Figure 4 As shown, a sterilization device for the production of biological drugs includes a box 100, an air suction mechanism 110, a purification mechanism 120, a driving mechanism 130 and a sterilization mechanism 150.

[0020] An exhaust groove 103 is provided on one side of the box body 100; an air suction mechanism 110 is installed in the box body 100, and the air suction mechanism 110 is used to suck external air into the box body 100; a purification mechanism 120 is installed in the box body 100, and the purification mechanism 120 is used to contain liquid for purifying air and to receive air exhausted by the air suction mechanism 110; a driving mechanism 130 is installed in the box body 100, and the driving mechanism 130 is used to stir the liquid in the purification mechanism 120; a sterilization mechanism 150 is installed above the purification mechanism 120, and the sterilization mechanism 150 is used to sterilize the air exhausted by the purification mechanism 120.

[0021] Specifically, by moving the device to a biopharmaceutical production workshop, and then starting the driving mechanism 130, the suction mechanism 110 starts to operate. When the suction mechanism 110 is in operation, it will suck the outside air into the box 100 and transport the air to the purification mechanism 120. The liquid in the purification mechanism 120 will purify the air. The purified air will enter the sterilization mechanism 150, which will sterilize the air. The sterilized air will eventually be discharged from the exhaust groove 103.

[0022] Through the operation of the driving mechanism 130, the air in the biological drug production workshop will enter the device, and the air will be sterilized by the purification mechanism 120 and the sterilization mechanism 150, thereby improving the quality of the air.

[0023] like Figure 3-Figure 6 As shown, the air suction mechanism 110 includes a fixing cylinder 111 , a filter plate 112 , a support frame 113 , a shaft 114 , a fan blade 115 , a second bevel gear 116 and an air delivery pipe 117 .

[0024] The fixed cylinder 111 is installed in the box body 100, and one end of the fixed cylinder 111 passes through one side of the box body 100; the filter plate 112 is installed in the fixed cylinder 111; the support frame 113 is installed in the fixed cylinder 111; the shaft 114 is rotatably connected to the support frame 113; the fan blade 115 is installed on the shaft 114; the second bevel gear 116 is fixedly sleeved on the shaft 114; the air pipe 117 is fixedly connected to the fixed cylinder 111, and a one-way valve is installed in the air pipe 117.

[0025] Specifically, when the shaft 114 rotates, the fan blades 115 are driven to rotate, and the rotating fan blades 115 will suck the outside air into the fixed cylinder 111, and the air in the fixed cylinder 111 will enter the air pipe 117. And because a one-way valve is installed in the air pipe 117, the air in the fixed cylinder 111 can only enter the air pipe 117 in one direction, and the outside air and liquid cannot enter the fixed cylinder 111 through the one-way valve. By providing the filter plate 112, large particles of debris in the air can be prevented from entering the fixed cylinder 111.

[0026] like Figure 3-Figure 5 As shown, the purification mechanism 120 includes a liquid box 121 , an air outlet groove 122 , two cross bars 123 , a plurality of first stirring bars 124 , two fourth bevel gears 125 , a fifth bevel gear 126 and a liquid adding pipe 127 .

[0027] The liquid box 121 is installed in the box body 100. The liquid box 121 is used to contain liquid for purifying air. The liquid for purifying air is disinfectant or alcohol. The air outlet groove 122 is provided on the top surface of the liquid box 121; two cross bars 123 are rotatably connected to the inner wall of the liquid box 121, and one of the cross bars 123 extends outside the liquid box 121; a plurality of first stirring rods 124 are respectively installed on the two cross bars 123; two fourth bevel gears 125 are respectively installed on the opposite ends of the two first stirring rods 124; the fifth bevel gear 126 is located outside the box body 100, and the fifth bevel gear 126 is fixedly connected to the cross bar 123; the liquid adding pipe 127 is installed on the liquid box 121, and the liquid adding pipe 127 extends outside the box body 100.

[0028] Specifically, the liquid for purifying air is added into the liquid tank 121 through the liquid adding pipe 127. When the air discharged from the air supply pipe 117 enters the liquid tank 121, the liquid in the liquid tank 121 will process the air, and the processed air will be discharged from the air outlet groove 122 to the outside of the liquid tank 121.

[0029] When air enters the liquid box 121, the two cross bars 123 are rotated to drive the first stirring bars 124 to rotate, thereby stirring the liquid in the liquid box 121, thereby increasing the contact area between the liquid and the air, thereby improving the treatment effect of the liquid on the air.

[0030] like Figure 3-Figure 6 As shown, the driving mechanism 130 includes a dual-axis motor 131 , a first bevel gear 132 , a reducer 133 , a vertical rod 134 , a second stirring rod 135 and a third bevel gear 136 .

[0031] The dual-axis motor 131 is installed on the fixed cylinder 111, and the dual-axis motor 131 has a first power output shaft and a second power output shaft, and the first power output shaft extends into the fixed cylinder 111; the first bevel gear 132 is installed at the lower end of the first power output shaft, and the first bevel gear 132 is meshed with the second power output shaft; the reducer 133 is installed on the bottom surface of the liquid tank 121, and the input end of the reducer 133 is connected to the second power output shaft of the dual-axis motor 131; the vertical rod 134 is fixedly connected to the output end of the reducer 133, and the vertical rod 134 passes through the bottom surface of the liquid tank 121 and is rotatably connected to the liquid tank 121; the second stirring rod 135 is located in the liquid tank 121, and the second stirring rod 135 is installed on the vertical rod 134; the third bevel gear 136 is fixedly sleeved on the vertical rod 134, and the third bevel gear 136 is meshed with the two fourth bevel gears 125.

[0032] Specifically, when the dual-axis motor 131 is running, the first power output shaft of the dual-axis motor 131 will drive the first bevel gear 132 to rotate, and then mesh to drive the second bevel gear 116 to rotate, and then drive the shaft 114 and the fan blades 115 to rotate, thereby sucking outside air into the fixed cylinder 111.

[0033] When the dual-axis motor 131 is running, the second power output shaft of the dual-axis motor 131 will drive the vertical rod 134 to rotate through the reducer 133, and then drive the third bevel gear 136 to rotate, and then mesh and drive the two fourth bevel gears 125 to rotate; and when the vertical rod 134 rotates, it will also drive the second stirring rod 135 to rotate, and then the second stirring rod 135 will stir the liquid in the liquid tank 121, thereby increasing the contact area between the liquid and the air.

[0034] like Figure 3 and Figure 4 As shown, the sterilization mechanism 150 includes a plurality of first partitions 151 , a plurality of second partitions 152 , and a plurality of ultraviolet lamps 153 .

[0035] Multiple first partitions 151 are installed on the inner top surface of the box body 100; multiple second partitions 152 are installed on the top surface of the liquid box 121, and the multiple second partitions 152 are spaced apart from the multiple first partitions 151; multiple ultraviolet lamps 153 are installed on the inner top surface of the box body 100.

[0036] Specifically, an air flow channel is formed between the multiple first partitions 151 and the multiple second partitions 152. The air discharged through the liquid box 121 will enter the air flow channel and finally be discharged through the exhaust groove 103. When the air flows in the air flow channel, the ultraviolet light emitted by the ultraviolet lamp 153 will sterilize the air and improve the air quality.

[0037] like Figure 1 and Figure 6 As shown, the sterilization device for biopharmaceutical production further includes two slideways 101 , two fixing plates 102 and a cleaning mechanism 140 .

[0038] The two slide grooves 101 are both opened on the side of the box body 100 ; the two fixing plates 102 are both installed on the side of the box body 100 .

[0039] The cleaning mechanism 140 includes a reciprocating screw 141, a sixth bevel gear 142, a cleaning brush 143 and two sliders 144. The reciprocating screw 141 is rotatably connected to the two fixed plates 102, and a reciprocating screw nut is installed on the reciprocating screw 141; the sixth bevel gear 142 is installed on the upper end of the reciprocating screw 141, and the sixth bevel gear 142 is meshed and connected with the fifth bevel gear 126; the cleaning brush 143 is fixedly sleeved on the reciprocating screw nut, and the cleaning brush 143 is used to clean the filter plate 112; the two sliders 144 are both installed on the cleaning brush 143, and the two sliders 144 are slidably connected to the two slide grooves 101 respectively.

[0040] Specifically, when the fifth bevel gear 126 rotates, it will mesh and drive the sixth bevel gear 142 to rotate, thereby driving the reciprocating screw 141 to rotate, thereby causing the reciprocating screw nut to move up and down, thereby driving the cleaning brush 143 to move back and forth up and down, and the moving cleaning brush 143 will clean the filter plate 112, thereby removing debris attached to the filter plate 112, thereby preventing the debris from clogging the filter plate 112 and affecting the filtering efficiency.

[0041] The slider 144 and the slide groove 101 are provided to improve the stability of the cleaning brush 143 when it moves.

[0042] Working principle: When in use, the device is moved to a biological drug production workshop, and then the air-purifying liquid (alcohol or disinfectant) is added into the liquid tank 121 through the liquid adding pipe 127 .

[0043] By starting the dual-axis motor 131, when the dual-axis motor 131 is running, the first power output shaft of the dual-axis motor 131 will drive the first bevel gear 132 to rotate, and then engage and drive the second bevel gear 116 to rotate, and then drive the shaft 114 and the fan blades 115 to rotate, thereby sucking the outside air into the fixed cylinder 111, and the air in the fixed cylinder 111 will be transported to the liquid tank 121 through the air pipe 117, and the liquid in the liquid tank 121 will process the air, and the processed air will be discharged from the air outlet groove 122 to the outside of the liquid tank 121.

[0044] When the dual-axis motor 131 is running, the second power output shaft of the dual-axis motor 131 will drive the vertical rod 134 to rotate through the reducer 133, and then drive the third bevel gear 136 to rotate, and then mesh and drive the two fourth bevel gears 125 to rotate, and then drive the two cross bars 123 to rotate, and then drive the multiple first stirring rods 124 to rotate, and then stir the liquid in the liquid tank 121, so as to increase the contact area between the liquid and the air, thereby improving the treatment effect of the liquid on the air. When the vertical rod 134 rotates, it will also drive the second stirring rod 135 to rotate, so that the second stirring rod 135 stirs the liquid in the liquid tank 121, thereby increasing the contact area between the liquid and the air.

[0045] The air discharged through the air outlet slot 122 will enter the sterilization mechanism 150, and the air will flow in the direction close to the exhaust slot 103. At this time, by starting the multiple ultraviolet lamps 153, the ultraviolet lamps 153 emit ultraviolet light, which sterilizes the air, thereby improving the quality of the air. By providing multiple first partitions 151 and multiple second partitions 152, the time that the air stays in the box 100 can be extended, thereby improving the sterilization effect.

[0046] Among them, when the cross bar 123 rotates, it will drive the fifth bevel gear 126 to rotate, and the fifth bevel gear 126 will engage and drive the sixth bevel gear 142 to rotate, thereby driving the reciprocating screw 141 to rotate, and then the reciprocating screw nut moves up and down, and then drives the cleaning brush 143 to move back and forth up and down, and the moving cleaning brush 143 will clean the filter plate 112, thereby clearing away debris attached to the filter plate 112, thereby preventing debris from clogging the filter plate 112 and affecting the filtration efficiency.

[0047] Example 2: Figure 1-Figure 6 As shown, a working method of a sterilization device for the production of biological drugs comprises the following steps: Step 1: Move the sterilization device into the biopharmaceutical production workshop, ensure that the device is stably placed, and the exhaust slot 103 faces the appropriate ventilation direction; Add air-purifying liquid (disinfectant or alcohol) into the liquid tank 121 through the liquid adding pipe 127. During the adding process, ensure that the amount of liquid is appropriate, neither too much to cause overflow nor too little to affect the purification effect; Step 2: Start the dual-axis motor 131. The first power output shaft of the dual-axis motor 131 drives the shaft 114 and the fan blades 115 to rotate, thereby sucking the outside air into the fixed cylinder 111, and then sending the air into the liquid tank 121 through the air delivery pipe 117; Step 3: The air entering the liquid tank 121 will come into contact with the liquid. At the same time, the second power output shaft of the dual-axis motor 131 drives the vertical rod 134 to rotate through the reducer 133, thereby driving the second stirring rod 135 to stir the liquid in the liquid tank 121, thereby increasing the contact area between the liquid and the air and improving the purification effect; and the third bevel gear 136 on the vertical rod 134 is meshed with the fourth bevel gear 125 in the liquid tank 121, driving the cross bar 123 and the first stirring rod 124 to rotate, thereby further stirring the liquid; Step 4: The air purified by the liquid box 121 is discharged from the air outlet slot 122 and enters the sterilization mechanism 150. By starting the ultraviolet lamp 153, the ultraviolet light irradiates and sterilizes the air to kill the remaining microorganisms; Step 5: The sterilized air passes through the air flow channel and is finally discharged from the exhaust slot 103.

A method for using the sterilization device for biopharmaceutical production according to claim 5, characterized in that: The following steps are involved: Step 1: adding air-purifying liquid into the liquid tank (121) through the liquid adding pipe (127); Step 2: starting the dual-axis motor (131); the first power output shaft of the dual-axis motor (131) drives the shaft (114) and the fan blades (115) to rotate, thereby sucking outside air into the fixed cylinder (111), and then sending the air into the liquid tank (121) through the air delivery pipe (117); Step 3: The air entering the liquid box (121) will come into contact with the liquid. At the same time, the second power output shaft of the dual-axis motor (131) drives the vertical rod (134) to rotate through the reducer (133), thereby driving the second stirring rod (135) to stir the liquid in the liquid box (121), thereby increasing the contact area between the liquid and the air, and allowing the liquid to purify the air. Step 4: the air purified by the liquid box (121) is discharged from the air outlet slot (122) and enters the sterilization mechanism (150). The ultraviolet light (153) is activated to sterilize the air with ultraviolet light, thereby killing the remaining microorganisms. Step 5: The sterilized air passes through the air flow channel and is finally discharged from the exhaust groove (103).
