[0001] The utility model relates to the technical field of sterilization tanks, in particular to an EM stock solution sterilization tank. Background Art

[0002] EM stands for effective microbial community. The stock solution is the name relative to the expanded culture solution (also called active solution). In situations where large quantities are required (such as environmental treatment projects, etc.), in order to save costs, it is recommended to expand the probiotic stock solution and make it into active solution, which requires the use of a sterilization tank.

[0003] According to the Chinese patent with the authorized publication number CN212174949U, an EM stock solution sterilization tank is disclosed. The stock solution flows into the first shell from the third discharge hopper, and the UV lamp is started to sterilize the stock solution by irradiation, and then the stock solution is discharged from the second discharge hopper. In actual use of the above scheme, the stock solution is directly discharged from the second discharge hopper after passing through the transparent cover, so that the contact time between the stock solution and the ultraviolet light emitted by the UV lamp is short, and the contact area between the stock solution and the ultraviolet light emitted by the UV lamp during the circulation process is relatively limited, which results in the stock solution failing to achieve the expected sterilization effect, reducing the practicality of the existing EM stock solution sterilization tank.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: an EM stock solution sterilization tank, comprising a tank body 1, a tank cover 2 is hingedly connected to the top of the tank body 1 through a hinge, a feed pipe 3 is fixed to the top of the tank cover 2, a discharge pipe 5 is fixed to the bottom of the tank body 1, a filter assembly 200 for filtering the stock solution is installed inside the tank body 1, and a sterilization assembly 300 for sterilizing the stock solution is installed inside the tank body 1;

[0024] Through the coordinated use of the tank body 1, the filter component 200 and the sterilization component 300, the stock solution can be retained in the sterilization tank during actual use, thereby effectively ensuring that the stock solution is in contact with the ultraviolet rays emitted by the UV lamp for a longer time, and the stock solution in the tank can also be effectively stirred, thereby increasing the contact area between the stock solution and the ultraviolet rays emitted by the UV lamp, thereby ensuring that the expected sterilization effect of the stock solution can be achieved. At the same time, the filter plate can be conveniently and effectively removed from the sterilization tank for cleaning, ensuring the normal use of the filter plate and improving the practicality of the EM stock solution sterilization tank.

[0025] In this embodiment, the filter assembly 200 is a structure for filtering the raw liquid.

[0026] like Figure 1 and Figure 2As shown, the filter assembly 200 includes an annular plate 201 fixed to the inside of the tank body 1, a through hole 202 is opened at the bottom of the annular plate 201, a mounting groove 203 is opened at the top of the annular plate 201, a filter screen 204 is slidably connected inside the mounting groove 203, and two handles 205 are fixed on the top of the filter screen 204.

[0027] It should be noted that the top of the through hole 202 is connected to the mounting groove 203 , and the diameter of the mounting groove 203 is larger than the diameter of the through hole 202 , so as to ensure that the stock solution can flow into the bottom of the tank body 1 through the through hole 202 .

[0028] In addition, two fixing columns 4 are fixed to the bottom of the tank body 1, so that the tank body 1 is fixed more stably. The diameter of the filter screen 204 is equal to the diameter of the installation groove 203, ensuring that the filter screen 204 is installed more stably in the installation groove 203 and fully filters the raw liquid.

[0029] In this embodiment, the sterilization component 300 is a structure for effectively sterilizing the stock solution.

[0030] like Figure 1 and Figure 3 As shown, the sterilization component 300 includes a triangular prism 301 fixed to the inside of the tank body 1, a motor 302 is fixed to the bottom of the triangular prism 301, and fixing rods 303 are fixed to the left and right sides of the motor 302, a stirring rod 304 is fixed to the output shaft of the motor 302, and a plurality of stirring blades 305 are fixed to the outside of the stirring rod 304, and the bottom end of the stirring rod 304 is rotatably connected to a mounting plate 306 through a bearing, and limiting rods 307 are fixed to the left and right sides of the mounting plate 306, two guide plates 308 are fixed to the inner bottom wall of the tank body 1, transparent covers 309 are fixed to the inner left and right walls of the tank body 1, and UV lamp bodies 310 are fixed to the inner left and right walls of the tank body 1.

[0031] It should be noted that the opposite ends of the two fixing rods 303 are respectively fixed to the inner left wall and the inner right wall of the tank body 1, so as to effectively fix the fixing rods 303, and the opposite ends of the two limiting rods 307 are respectively fixed to the inner left wall and the inner right wall of the tank body 1, so as to effectively fix the limiting rods 307.

[0032] In addition, a discharge pipe 5 is fixed to the bottom of the tank body 1, and a solenoid valve 6 is fixed to the outside of the discharge pipe 5 to ensure that the discharge of the raw liquid can be controlled.

[0033] In addition, the UV lamp body 310 is located inside the transparent cover 309 to ensure that the UV lamp body 310 can work correctly and safely. By judging the original liquid, the appropriate time for irradiating the UV lamp body 310 is determined to ensure that the expected sterilization effect can be achieved. The front and back of the triangular prism 301 are respectively fixed to the front and back of the tank body 1 to fix the triangular prism 301.

[0034] The working principle of the above embodiment is:

[0035] During use, the stock liquid is added into the tank body 1 through the feed pipe 3, and then filtered through the filter screen 204, and then diverted through the triangular prism 301, and then the motor 302 is turned on to drive the stirring rod 304 and the stirring blade 305 to rotate in situ, and at the same time, the UV lamp body 310 is turned on to sterilize the stock liquid in the tank body 1. At this time, the battery valve 6 is in a closed state, and the stirring blade 305 stirs the stock liquid, thereby increasing the contact area between the stock liquid and the ultraviolet rays emitted by the UV lamp body 310, so as to achieve the expected sterilization effect and improve the sterilization efficiency. When the expected time is reached, the solenoid valve 6 is opened, and the sterilized stock liquid is discharged through the discharge pipe 5. After the tank body 1 has been used for a period of time, the tank cover 2 can be opened, and the filter screen 204 can be taken out upward from the annular plate 201 through the handle 205, so that the filter screen 204 can be effectively cleaned, ensuring the subsequent normal use, and the operation is relatively simple.

[0036] Compared with the prior art, the EM stock solution sterilization tank, through the coordinated use of the tank body 1, the filter component 200 and the sterilization component 300, can retain the stock solution in the sterilization tank during actual use, thereby effectively ensuring that the stock solution is in contact with the ultraviolet rays emitted by the UV lamp for a longer time, and can also effectively stir the stock solution in the tank, thereby increasing the contact area between the stock solution and the ultraviolet rays emitted by the UV lamp, thereby ensuring that the expected sterilization effect of the stock solution can be achieved. At the same time, the filter plate can be conveniently and effectively removed from the sterilization tank for cleaning, ensuring the normal use of the filter plate, improving the practicality of the EM stock solution sterilization tank, and solving the problem of low practicality of the existing EM stock solution sterilization tank.

[0037] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of an external power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
