They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] A wastewater treatment device for use in printing presses, such as Figures 1-6 As shown, the device includes a main body, which includes a mounting frame 1 mounted on the outer wall of the printing machine, a connecting seat 2 rotatably connected to the mounting frame 1, a limiting component on the mounting frame 1 for limiting the rotation of the connecting seat 2, and several through slots 3 opened on the connecting seat 2. The several through slots 3 are arranged in a circular array and each of them is detachably connected to a mounting tube 4. A connecting tube 5 is sleeved on the top of the mounting tube 4, and the end of the connecting tube 5 away from the mounting tube 4 is threadedly connected to the drain pipe on the printing machine. Several boxes 6 that communicate with the through slots 3 are installed at the bottom of the connecting seat 2. A stirring component is installed inside the box 6, and a discharge component is installed at the bottom of the box 6. A guiding component for introducing the treatment agent into the box 6 is provided on the connecting seat 2.

[0028] The mounting bracket 1 is fixedly connected to a first motor 7 and a control panel 8 for controlling the operation of the first motor 7. A drive wheel 9 is fixedly connected to the output end of the first motor 7. A driven wheel 10 is fixedly connected to the bottom of the connecting seat 2 through a connecting shaft. The drive wheel 9 and the driven wheel 10 mesh with each other. The control panel 8 drives the first motor 7 to work. Since the drive wheel 9 is fixedly connected to the output end of the first motor 7, the drive wheel 9 starts to rotate. At the same time, the driven wheel 10 meshing with the drive wheel 9 also rotates. Since the driven wheel 10 is fixed to the bottom of the connecting seat 2 through a connecting shaft, the connecting seat 2 also starts to rotate when the driven wheel 10 rotates.

[0029] The limiting component includes several positioning blocks fixedly connected to the top of the connecting seat 2 and an infrared receiver 12 set on the outer wall of the printing machine. The positions of the positioning blocks correspond one-to-one with the through slots 3. An infrared transmitter 11 is set on the side wall of the positioning block. Both the infrared transmitter 11 and the infrared receiver 12 are connected to the control panel 8. When the infrared receiver 12 receives the signal transmitted by the infrared transmitter 11, the control panel 8 drives the first motor 7 to stop working. The control panel 8 starts the required infrared transmitter 11 and simultaneously starts the infrared receiver 12 on the outer wall of the printing machine. Then, the first motor 7 is started to drive the connecting seat 2 to rotate. When the connecting seat 2 rotates to the point where the signal transmitted by the infrared transmitter 11 is received by the infrared receiver 12, the control panel 8 automatically drives the first motor 7 to stop working, thereby stopping the rotation of the connecting seat 2 and improving the degree of automation.

[0030] The stirring assembly includes a second motor 13 fixedly connected to the outer wall of the tank 6 and a rotating shaft fixedly connected to the output end of the second motor 13. The second motor 13 is connected to the control panel 8. The rotating shaft extends into the interior of the tank 6 and has several stirring rods 14 fixedly connected to its outer wall. The control panel 8 drives the output end of the second motor 13 to rotate. Since the rotating shaft is fixedly connected to the output end of the second motor 13, the rotating shaft also starts to rotate. Since several stirring rods 14 are fixedly connected to the outer wall of the rotating shaft, the stirring rods 14 also start to rotate when the rotating shaft rotates, thereby achieving the stirring effect, accelerating the reaction between the sewage and the treatment agent in the tank 6, and increasing the degree of reaction.

[0031] An elastic scraper 15 is fixedly connected to the end of the stirring rod 14 away from the rotating shaft. The elastic scraper 15 is in contact with the inner wall of the box 6. The elastic scraper 15 can rotate together with the stirring rod 14 when it rotates, and scrape off the material adhering to the inner wall of the box 6 to prevent it from affecting the next use. In addition, the elastic scraper 15 has the property of elastic deformation, which can prevent the elastic scraper 15 from scratching the inner wall of the box 6, thereby improving the service life of the box 6.

[0032] The material guiding assembly includes several mounting slots 16 formed on the connecting seat 2 and a storage box 17 placed in the mounting slots 16. The top of the storage box 17 is hinged to a cover 18. The bottom of the storage box 17 is connected to the box 6 through a conduit 19. The conduit 19 is inclined and the lowest point is where it connects to the box 6. The storage box 17 is provided with a blocking member for sealing the connection between itself and the conduit 19. The storage box 17 is provided with a control member for controlling the operation of the blocking member. When the cover 18 is opened, the corresponding treatment agent is put into the storage box 17. After the cover 18 is closed, the control member is used to control the blocking member to open the connection between the storage box 17 and the conduit 19. At this time, the treatment agent will fall into the conduit 19 and then into the box 6 through the conduit 19, thereby achieving the effect of guiding the treatment agent into the box 6. When material guiding is not needed, the control member can be used to control the blocking member to seal the connection between the storage box 17 and the conduit 19.

[0033] The blocking component includes a connecting ring 20 fixedly connected to the connection between the storage box 17 and the conduit 19, and a baffle 21 disposed within the connecting ring 20. The outer wall of the baffle 21 and the inner wall of the connecting ring 20 are connected to each other by a connecting mesh 22. A control component is used to control the up and down movement of the baffle 21. When the baffle 21 and the connecting ring 20 are at the same horizontal plane, the connecting ring 20, the baffle 21, and the connecting mesh 22 together seal the connection between the storage box 17 and the conduit 19. The control component controls the movement of the baffle 21. When the baffle 21 moves to the same horizontal plane as the connecting ring 20, the connecting ring 21... 0. The baffle 21 and the connecting mesh 22 seal the connection between the storage box 17 and the conduit 19, thereby preventing the treatment agent in the storage box 17 from falling into the conduit 19. When the baffle 21 is moved above or below the connecting ring 20 by the control component, since the baffle 21 and the connecting ring 20 are connected by the connecting mesh 22, the connecting mesh 22 will be opened when there is a height difference between the baffle 21 and the connecting ring 20. The treatment agent can fall into the conduit 19 through the mesh holes on the connecting mesh 22, thereby controlling the sealing and opening of the connection between the storage box 17 and the conduit 19.

[0034] The control components include a sliding groove on the side wall of the storage box 17, a sliding rod 23 slidably connected in the sliding groove, a connecting rod 24 fixedly connected to the side wall of the sliding rod 23, the connecting rod 24 penetrating into the interior of the storage box 17, and a moving groove 25 for the connecting rod 24 to move on the inner wall of the storage box 17. A moving rod 26 is fixedly connected to the end of the connecting rod 24 away from the sliding rod 23. The moving rod 26 is fixedly connected to the center of the baffle 21. Pulling the sliding rod 23 causes the connecting rod 24 to move. Since the connecting rod 24 is fixedly connected to the moving rod 26, and the moving rod 26 is fixedly connected to the baffle 21, the baffle 21 will also move along with it, thereby achieving the effect of controlling the movement of the baffle 21. This is simple and convenient. Furthermore, the moving rod 26 is connected to the center of the baffle 21, which can prevent the baffle 21 from tilting during the process of the moving rod 26 moving the baffle 21.

[0035] The discharge assembly includes a discharge pipe 27 fixedly connected to the side wall of the housing 6 and communicating with the inside of the housing 6, and a valve body 28 connected to the control panel 8 on the discharge pipe 27. The opening and closing of the discharge pipe 27 can be controlled by controlling the operation of the valve body 28 through the control panel 8, which is simple and convenient.

[0036] The present invention is used normally as follows:

[0037] Select the appropriate treatment agent according to the ink used in the printing press and use the material guiding component to introduce the treatment agent into the housing 6. Then, rotate the connecting seat 2 to align the corresponding through groove 3 and mounting pipe 4 of the housing 6 with the sewage pipe of the printing press. Next, rotate the connecting pipe 5 sleeved on the top of the mounting pipe 4 to connect it with the sewage pipe, and use the limiting component to fix the position of the connecting seat 2. Then, the sewage generated after the printing press is working is discharged through the sewage pipe. Since the sewage pipe is connected to the connecting pipe 5 and the connecting pipe 5 is connected to the mounting pipe 4, the sewage will flow into the housing 6 along the connecting pipe 5 and the mounting pipe 4. Then, start the stirring component to fully mix and react the sewage and treatment agent in the housing 6. After the treatment is completed, use the material discharge component to discharge the treated mixture in the housing 6. This is how the sewage generated during the operation of the printing press is treated. When the type of ink is changed, simply replace the corresponding treatment agent and the housing 6. It is simple and convenient.

[0038] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
