Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Embodiment 1

[0024] Please refer to the attached Figure 1-2 , a flash evaporation tank provided with a filtering assembly, including:

[0025] A tank body 1, a stirring assembly 2 and a filtering assembly 3. The tank body 1 includes an outer tank body 10 and an inner tank body 11 fixedly connected inside the outer tank body 10. An air outlet pipe 12 is provided on the top wall of the outer tank body 10, and an air inlet pipe 13 is provided on the side wall. A discharge pipe 14 and a water outlet pipe 15 are provided on the bottom wall of the inner tank body 11, and the other ends of the discharge pipe 14 and the water outlet pipe 15 pass through the bottom wall of the outer tank body 10 and are fixedly connected thereto. The stirring assembly 2 is movably connected to the top wall of the outer tank body 10, and the filtering assembly 3 is fixedly connected to the tank body 1 through a connecting frame 4.

[0026] Through the setting of the outer tank body 10 and the inner tank body 11, the fluid directly enters the inner tank body 11. The high-temperature steam enters the position between the outer tank body 10 and the inner tank body 11 through the air inlet pipe 13, so as to achieve the purpose that the fluid in the inner tank body 11 is at an appropriate temperature. At the same time, the condensed water formed by the high-temperature steam on the side wall of the inner tank body 11 can be discharged through the water outlet pipe 15, and the steam generated by the fluid in the inner tank body 11 is discharged through the air outlet pipe 12, and the remaining raw materials are discharged through the discharge pipe 14. During this process, the inner tank body 11 is stirred by the stirring assembly 2 to accelerate the fluid vaporization process, and at the same time, the fluid is filtered by the filtering assembly 3 to prevent a large amount of impurities from entering the inner tank body 11. It should be noted that in order to maintain the pressure of the inner tank body 11, a pressurizing device should be additionally provided. Considering the technical description of this device, it will not be elaborated in this invention.

[0027] Specifically, the stirring assembly 2 includes a stirring motor 20, a stirring shaft 21, and stirring blades 22. One end of the stirring shaft 21 is fixedly connected to the stirring blades 22 located in the inner tank 11, and the other end passes through the top wall of the outer tank 10 and is connected to the stirring motor 20. Moreover, the stirring shaft 21 is connected to the outer tank 10 through bearings. After the stirring motor 20 is powered on, it drives the stirring shaft 21 to rotate, and then drives the stirring blades 22 to stir the fluid located in the inner tank 11.

[0028] Specifically, the filtering assembly 3 includes a filter box 30, a filter screen 31, a water inlet pipe 32, and a connecting pipe 33. The filter screen 31 is horizontally and fixedly connected inside the filter box 30. The water inlet pipe 32 is fixedly connected to the top wall of the filter box 30. One end of the connecting pipe 33 is fixedly connected to the bottom wall of the filter box 30, and the other end passes through the top wall of the outer tank 10 and is fixedly connected thereto. Through the filter screen 31 provided inside the filter box 30, preliminary filtration of the fluid entering from the water inlet pipe 32 is achieved, and the filtered fluid enters the inner tank 11 through the connecting pipe 33.

[0029] Embodiment 2

[0030] Please refer to the appendix Figure 3

[0031] Specifically, the filtering assembly 3 includes a filter box 30, a filter screen 31, a water inlet pipe 32, a connecting pipe 33, an inclined block 34, and a vibration assembly 6. The water inlet pipe 32 is fixedly connected to the top wall of the filter box 30. One end of the connecting pipe 33 is fixedly connected to the bottom wall of the filter box 30, and the other end passes through the top wall of the outer tank 10 and is fixedly connected thereto. The inclined block 34 is fixedly connected to the bottom of the filter box 30 on the side away from the connecting pipe 33. The filter screen 31 is fixedly connected inside the filter box 30 in an inclined state, and the filter screen 31 is in contact with the inclined block 34. The vibration assembly 6 is fixedly connected to the inner wall of the filter box 30.

[0032] Considering that in the above embodiment, the filter screen 31 needs to be cleaned regularly during use. Otherwise, there will be a situation where there is too much sediment on the filter screen 31, and then the problem of poor filtering effect of the filter screen 31 will occur. Therefore, in this embodiment, the filter screen 31 is installed in an inclined manner. During use, the filtered impurities fall downward along the filter screen 31 under the action of gravity and slide along the inclined block 34 to the side close to the filter box 30 during long-term sedimentation. At the same time, for easy cleaning, a detachable cleaning window can be provided near the top of the filter box 30. Also, considering that there are some impurities adhering to the filter screen 31 and unable to fall under their own gravity, the vibration assembly 6 is provided to assist in cleaning the impurities on the filter screen 31 through vibration.

[0033] Specifically, the vibration assembly 6 includes a knocking hammer head 60, a knocking hammer handle 61, and a spring 62. One end of the spring 62 is fixedly connected to the side wall of the filter box 30, and the other end is fixedly connected to the knocking hammer head 60. One end of the knocking hammer handle 61 passes through the filter box 30 and the spring 62 and is fixedly connected to the knocking hammer head 60. And in the normal state of the spring 62, the knocking hammer head 60 contacts the filter net 31. When auxiliary cleaning of the impurities on the filter net 31 is required, the knocking hammer handle 61 is pulled. During this process, the movement of the knocking hammer head 60 will be driven, and at the same time, the spring 62 will be compressed through the knocking hammer handle 61. After releasing the knocking hammer handle 61, the knocking hammer head 60 will be driven by the reverse acting force of the spring 62 to knock the filter net 31, and the filter net 31 is cleaned by this knocking. It should be noted that the position of the vibration assembly 6 is considered to be close to the top wall of the filter box 30. Otherwise, it is possible that the vibration assembly 6 is located in the fluid, and the vibration effect will be affected by the fluid. At the same time, when the use frequency of the vibration assembly 6 is relatively high in actual application, the method of connecting an external cylinder to the vibration assembly 6 can also be considered to replace the function of the spring 62. This method has a more stable knocking amplitude and does not require the staff to manually knock the filter net 31.

[0034] Embodiment III

[0035] Please refer to the appendix Figure 4

[0036] Specifically, the filtering assembly 3 includes a filter box 30, an S-shaped elbow 35, a filter net 31, and a stirring wheel 36. The S-shaped elbow 35 is fixedly connected inside the filter box 30. One end of it passes through and is fixedly connected to the bottom wall of the filter box 30, and the other end passes through the bottom wall of the filter box 30 and the top wall of the outer tank body 10 and is fixedly connected to them. A residue collection pipe 350 fixedly connected to it is provided at the elbow of the S-shaped elbow 35 near the bottom wall of the filter box 30. The filter net 31 is fixedly connected at the position between the two elbows of the S-shaped elbow 35. The stirring wheel 36 is connected by a bearing inside the S-shaped elbow 35. It is located between the filter net 31 and the residue collection pipe 350, and the stirring wheel 36 contacts the filter net 31.

[0037] By adopting the setting of the S-shaped elbow 35 to replace the function of the filter box 30, the filtration of impurities in the fluid is completed through the filter net 31 provided inside the S-shaped elbow 35. At the same time, the filtered impurities can precipitate under the action of gravity and enter the residue collection pipe 350. At the same time, the rotation of the stirring wheel 36 will be driven during the flow of the fluid. During the rotation of the stirring wheel 36, it continuously contacts the filter net 31 and scrapes off the impurities that may adhere to the filter net 31, avoiding the situation that the fluid passing rate is slow due to excessive adhesion of impurities on the filter net 31.

[0038] Specifically, a residue collection box 351 detachably connected to the residue collection pipe 350 is provided at one end of the residue collection pipe 350 far from the S-shaped elbow 35. In order to facilitate the collection and treatment of impurities, a detachable residue collection box 351 is provided, and the rapid collection of impurities can be completed by regular replacement.

[0039] Specifically, a control valve 352 movably connected to the residue collection pipe 350 is provided inside the residue collection pipe 350. Considering that there may be a situation where fluid flows out of the residue collection pipe 350 when replacing the residue collection box 351, a control valve 352 is provided inside the residue collection pipe 350, and the control valve 352 can be closed when the residue collection box 351 needs to be replaced.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
