Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a stainless steel cleaning wastewater recycling device. Background Art

[0002] Stainless steel products often need to be cleaned during the manufacturing process to keep the surface of the stainless steel products clean, remove oxides on the surface of the stainless steel products to avoid affecting the appearance and quality, and remove potential rust to extend the service life of the stainless steel products. The surface of the cleaned stainless steel products is easier to carry out subsequent surface treatments such as polishing, spraying, and electroplating.

[0003] The waste water after stainless steel cleaning is recycled and treated for utilization, and then the recycled waste water can be reused after certain treatment. When treating the waste water, the impurities in the waste water often adhere to the filter, causing the filter to be blocked. In the long run, it is easy to cause the filter to rust, affecting the treatment effect of the filter. Utility Model Content

[0004] The utility model aims to provide a device for recycling waste water from cleaning stainless steel.

[0005] The technical problem solved by the utility model is that impurities blocked on the filter screen are likely to reduce the processing efficiency of the filter screen and also easily cause the filter screen to rust, thereby affecting the processing effect of the filter screen.

[0006] The utility model can be realized through the following technical scheme: a stainless steel cleaning wastewater recycling and reuse device comprises a wastewater tank, a treatment pipe is fixedly connected to the bottom of one side of the wastewater tank, a filter screen and a one-way liquid inlet valve are fixedly installed on the inner wall of the treatment pipe from left to right in sequence, a scraper brush assembly is installed on the filter screen, a push-pull rod is slidably provided through the top of the outer wall of the treatment pipe, the bottom end of the push-pull rod is rotatably connected to one end of the scraper brush assembly, a liquid outlet pipe is fixedly connected to the side of the treatment pipe away from the wastewater tank, a piston cylinder is fixedly connected to the top of the outer wall of the treatment pipe, a piston rod is slidably provided through the top of the piston cylinder, and a transmission mechanism is installed at the same time as the push-pull rod and the top of the piston rod.

[0007] A further technical improvement of the utility model is that an adsorption plate is slidably provided through the bottom of the wastewater tank on one side away from the treatment pipe. The adsorption plate is made of polymer resin and is used to adsorb impurities precipitated in the wastewater to avoid the impurities being driven by the flow of wastewater to dissolve again in the wastewater when the wastewater is treated, thereby improving the impurity removal effect on the wastewater.

[0008] Furthermore, the scraper brush assembly includes a rotating rod that is rotatably installed passing through the center position of the filter screen, and scraper brush plates are fixedly installed at both ends of the rotating rod. A brush is fixedly installed on the side of the scraper brush plate adjacent to the filter screen, and the side of the brush away from the scraper brush plate is in contact with the filter screen. One of the scraper brush plates is rotatably connected to the end away from the rotating rod with a traction rod, and the end of the traction rod away from the scraper brush plate is rotatably connected to the bottom end of the push-pull rod.

[0009] Furthermore, an outer circumferential wall of the liquid outlet pipe is provided with an external thread, a water pipe adapted to the liquid outlet pipe is provided on one side of the liquid outlet pipe, an inner circumferential wall of the water pipe adjacent to the liquid outlet pipe is provided with an internal thread adapted to the external thread, the water pipe is connected to the liquid outlet pipe through the external thread and the internal thread, and the treated wastewater discharged from the liquid outlet pipe is transported to other equipment for reuse through the water pipe.

[0010] Furthermore, the transmission mechanism includes a fixed plate fixedly connected to one side of the wastewater tank, a first connecting plate is rotatably connected to one side of the fixed plate, an end of the first connecting plate away from the fixed plate is rotatably connected to a second connecting plate, an end of the second connecting plate away from the first connecting plate is rotatably connected to a push-pull plate, and the bottom of the push-pull plate is fixedly connected to the piston rod and the top of the push-pull rod at the same time.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The rotating first connecting plate of the present application drives the push-pull plate to move up and down through the second connecting plate, so that the push-pull rod drives the scraper plate to scrape the surface of the filter screen through the traction rod, and the piston rod reciprocates up and down in the piston cylinder, thereby cleaning the impurities adsorbed on the surface of the filter screen while treating the wastewater to avoid clogging of the filter screen.

[0013] 2. The present application sets an adsorption plate at the bottom of the wastewater tank to adsorb impurities precipitated in the wastewater when the device is stationary, so that the impurities adsorbed on the adsorption plate will not dissolve in the wastewater again, preventing the impurities precipitated during the wastewater treatment from dissolving in the wastewater again, thereby facilitating the subsequent treatment of the wastewater.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-3 As shown, this embodiment provides a stainless steel cleaning wastewater recycling and reuse device, including a wastewater tank 1, an adsorption plate 2 is slidably installed through the bottom of one side of the wastewater tank 1, the adsorption plate 2 is made of polymer resin and has a certain adsorption capacity for sediments, the other side of the wastewater tank 1 is fixedly connected with a treatment pipe 3, the side of the treatment pipe 3 away from the wastewater tank 1 is fixedly connected with a liquid outlet pipe 4, the bottom of the treatment pipe 3 is provided with a support frame for supporting the treatment pipe 3, the outer peripheral wall of the liquid outlet pipe 4 is provided with an external thread 5, one side of the liquid outlet pipe 4 is provided with a water pipe 6 adapted to the liquid outlet pipe 4, and the inner peripheral wall of the water pipe 6 is provided with an internal thread 7 adapted to the external thread 5 at one end thereof near the liquid outlet pipe 4, and the water pipe 6 is connected to the liquid outlet pipe 4 through the cooperation of the internal thread 7 and the external thread 5;

[0021] A filter screen 8 is fixedly connected to the inner peripheral wall of the treatment tube 3 near the wastewater tank 1, a rotating rod 9 is rotatably connected to the center of the filter screen 8, and scraper plates 10 are fixedly installed at both ends of the rotating rod 9. The two scraper plates 10 are symmetrical with each other with the rotating rod 9 as the central axis. A brush 11 that fits the filter screen 8 is fixedly installed on one side of the scraper plate 10 near the filter screen 8, and a push-pull rod 12 is slidably installed at the top of the outer peripheral wall of the treatment tube 3 near the filter screen 8. A traction rod 13 is rotatably connected to the bottom end of the push-pull rod 12, and the end of the traction rod 13 away from the push-pull rod 12 is rotatably connected to the end of the scraper plate 10 away from the rotating rod 9;

[0022] Push the push-pull rod 12 downward, so that the push-pull rod 12 drives the traction rod 13 to pull the end of the scraper plate 10 at one end of the rotating rod 9 downward, so that the scraper plate 10 drives the rotating rod 9 to rotate clockwise at the center of the filter screen 8, and the rotating rod 9 drives the scraper plate 10 at the other end to rotate. Conversely, the push-pull rod 12 drives the two scraper plates 10 to rotate counterclockwise on the surface of the filter screen 8 through the traction rod 13. When the two scraper plates 10 rotate clockwise or counterclockwise, they will drive the brush 11 to scrape the surface of the filter screen 8;

[0023] A piston cylinder 14 is fixedly connected to the top of the outer peripheral wall of the processing tube 3 near the liquid outlet pipe 4, and a one-way liquid inlet valve 15 is fixedly installed at the position of the inner peripheral wall of the processing tube 3 between the piston cylinder 14 and the filter screen 8. The one-way liquid inlet valve 15 allows the liquid in the processing tube 3 to flow to the side of the piston cylinder 14 only through the side of the filter screen 8. A piston rod 16 is slidably connected to the top of the piston cylinder 14, and the piston arranged at the bottom end of the piston rod 16 is in contact with the inner peripheral wall of the piston cylinder 14. A push-pull plate 17 is fixedly installed on the top of the push-pull rod 12 and the piston rod 16 at the same time. A fixed plate 18 is fixedly installed on the side of the wastewater tank 1 near the processing tube 3, and a first connecting plate 19 is rotatably installed on the fixed plate 18. A driving motor for driving the first connecting plate 19 to rotate is installed on the fixed plate 18. The end of the first connecting plate 19 away from the fixed plate 18 is rotatably connected to the second connecting plate 20, and the end of the second connecting plate 20 away from the first connecting plate 19 is rotatably connected to one side of the push-pull plate 17.

[0024] The rotating first connecting rod drives the push-pull plate 17 to move reciprocatingly up and down through the second connecting rod. When the push-pull plate 17 moves upward, it will drive the piston rod 16 and the push-pull rod 12 to move upward at the same time. At this time, the piston at the bottom end of the piston rod 16 moves upward along the inner wall of the piston cylinder 14. At this time, the wastewater in the wastewater tank 1 will pass through the filter screen 8 and the one-way liquid inlet valve 15 in succession and finally flow into the treatment pipe 3. Conversely, the piston at the bottom end of the piston rod 16 will move downward along the inner wall of the piston cylinder 14, thereby squeezing the wastewater flowing into the treatment pipe 3 to the liquid outlet pipe 4, and flowing into the water pipe 6 through the liquid outlet pipe 4, and then flowing to other equipment through the water pipe 6 for reuse.

[0025] When the utility model is in use, when the device is in a stationary state, the wastewater in the wastewater tank 1 is precipitated due to the stationary state. At this time, the precipitate precipitated on the adsorption plate 2 at the bottom of the wastewater tank 1 is adsorbed by the adsorption plate 2. When the wastewater in the wastewater tank 1 is treated, the adsorption plate 2 can be pulled out of the wastewater tank 1, and the adsorption plate 2 can be cleaned.

[0026] The rotating first connecting rod drives the push-pull plate 17 to reciprocate up and down through the second connecting rod, so that the push-pull plate 17 drives the push-pull rod 12 and the piston rod 16 to reciprocate up and down. The push-pull rod 12 that reciprocates up and down will drive the two scraping and brushing plates 10 to rotate clockwise or counterclockwise on both sides of the filter screen 8, thereby removing impurities adsorbed on the filter screen 8. The piston rod 16 that moves up and down sucks the wastewater in the wastewater tank 1 into the treatment pipe 3, so that the wastewater is processed by the filter screen 8 and flows into the liquid outlet pipe 4, and flows into the water pipe 6 through the liquid outlet pipe 4, and is transported to the designated location by the water pipe 6 for utilization.
