Description
Technical Field
[0001] The utility model belongs to the technical field of salt production, and particularly relates to a collection, discharge and switching mechanism and a processing system for centrifuge post-flushing liquid. Background Art
[0002] In the well salt industry, the salt slurry formed by the evaporation and crystallization of the raw brine is centrifuged and dehydrated by the salt making centrifuge, and the resulting liquid after the liquid is mainly saturated brine containing a large number of small-particle salt crystals. At present, most salt-making companies return this type of liquid after the liquid is returned to the salt-making system through fixed pipelines for collection and reuse. In actual operation, this process of collecting and reusing through fixed pipelines, especially when the centrifuge is performing brush car maintenance, the wastewater with extremely low salt content generated by the brush car will inevitably be mixed into the salt-making system. These wastewaters do not increase the salt production capacity in the subsequent evaporation process but consume a large amount of steam, which invisibly pushes up the energy consumption of the entire salt-making system.

[0019] like Figure 1 As shown, the present application provides a collection and discharge switching mechanism for the after-spin liquid of a centrifuge, comprising a guide rail 1 and a liquid collecting container 2 arranged on the guide rail 1 and capable of linear reciprocating motion along the guide rail 1, the top of the liquid collecting container 2 is an opening structure for receiving the after-spin liquid discharged from the centrifuge 6, and the liquid collecting container 2 is provided with a discharge port 2-5 for discharging the after-spin liquid.
[0020] The two sides of the liquid collecting container 2 are respectively provided with rollers 3 which match the guide rail 1. The guide rail is directly made of 14b# stainless steel channel steel, and the dimensions of the two guide rails are 1600×140×58 mm. The base supporting the guide rail is made of 16# stainless steel channel steel vertically welded into a U-shaped structure with dimensions of 1100×700 mm.
[0021] Specifically, the liquid collecting container 2 is formed into a rectangular structure with an upper opening by a bottom plate 2-1, a front baffle plate 2-2, a rear baffle plate 2-3 and two side baffle plates 2-4, and the discharge port 2-5 is arranged on the bottom plate 2-1. The size of the bottom plate 2-1 is 1100×600 mm, the size of the side baffle plate 2-4 is 1100×500 mm, the size of the rear baffle plate 2-3 is 600×500 mm, and the size of the discharge port 2-5 is φ250×50 mm.
[0022] Preferably, the front baffle plate 2-2 is provided with a rectangular notch 2-6, and the size of the rectangular notch 2-6 is 600×200 mm. The rectangular notch 2-6 can prevent the upper large diameter end of the after-spinning liquid discharge pipe 6-1 from colliding with the front baffle plate 2-2 during the movement of the liquid collecting container 2, and facilitates the observation of the flow size and flow state of the after-spinning liquid during production.
[0023] Furthermore, a positioning block 4 is provided at the starting end of the guide rail 1; the positioning block 4 can facilitate the connection between the discharge port 2-5 of the liquid collecting container 2 and the liquid inlet of the mixed brine bucket 8 during the switching process, thereby avoiding liquid leakage, splashing or other problems, and improving efficiency and safety. A stop block 5 is provided at the end of the guide rail 1 to prevent the liquid collecting container 2 from derailing on the guide rail 1.
[0024] Furthermore, the liquid collecting container 2 is provided with a traction rope for driving the liquid collecting container 2 to move on the guide rail 1, and the liquid collecting container 2 located on the opposite side of the traction rope is provided with an elastic member for pulling the liquid collecting container 2 to reset. Specifically, the elastic member, one end of the spring is fixedly connected to the liquid collecting container 2, and the other end is installed on a fixed object arranged opposite to the liquid collecting container 2, such as the opposite side wall (wall), the mounting base and other structures, so that the tension of the spring and the traction of the traction rope form an interaction force. The elastic member can quickly pull the liquid collecting container 2 to reset after the traction rope is released, thereby improving the working efficiency of the structure, and at the same time has a certain buffering capacity during the movement process.
[0025] like Figure 2 The present application further provides a system for treating the liquid after the centrifuge 6, wherein the centrifuge 6 is provided with a liquid after the centrifuge discharge pipe 6-1 for discharging the liquid after the centrifuge, wherein the liquid after the centrifuge discharge pipe 6-1 is a reducer, wherein the large diameter end of the liquid after the centrifuge discharge pipe 6-1 is connected to the centrifuge 6, and the system comprises a wastewater collecting and distributing tank 7 arranged below the centrifuge 6, wherein the wastewater collecting and distributing tank 7 corresponding to the position of the liquid after the centrifuge discharge pipe 6-1 is provided with an independent guide channel and a mixed brine bucket 8;
[0026] It also includes a switching mechanism as mentioned above, which is used to switch the discharge position of the thrown-out liquid between the mixed brine barrel 8 and the wastewater collection and distribution tank 7. The fixed end of the guide rail 1 of the switching mechanism is fixedly arranged on the wall of the wastewater collection and distribution tank 7, and the free end of the guide rail 1 extends away from the mixed brine barrel 8; the small diameter end of the after-throwing liquid discharge pipe 6-1 extends into the liquid collecting container 2.
[0027] When the centrifuge 6 is working to make salt, the switching mechanism is located above the mixed brine barrel 8, the discharge port 2-5 of the liquid collecting container 2 is connected to the liquid inlet of the mixed brine barrel 8, and the liquid after the liquid is thrown flows into the mixed brine barrel 8 through the liquid collecting container 2. When the centrifuge 6 is maintained by brushing, the liquid collecting container 2 is driven to move along the guide rail 1, so that the discharge port 2-5 of the liquid collecting container 2 is placed above the wastewater collection and distribution tank 7, and the wastewater flows into the wastewater collection and distribution tank 7 through the liquid collecting container 2.
[0028] The above technical solution simplifies the process of collecting the liquid after the centrifuge 6 and discharging the water from the washing car, significantly improving the efficiency and safety of the entire work process. The collection and discharge process of the liquid after the centrifuge 6 and the washing car water are programmed and standardized, ensuring the accuracy and consistency of the work.
