Specific embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Before distilling the waste liquid, the existing distillation equipment usually separates the solid particles and suspended substances in the waste liquid through a filter screen first. When a certain amount of solid particles accumulates on the filter screen, the staff still needs to manually remove the filter screen for cleaning. The frequent disassembly and assembly of the filter screen and the cleaning work will affect the processing progress of the waste liquid by the equipment, and also increase the workload of the staff, affecting the distillation efficiency of the equipment.

[0025] To solve the defects existing in the above distillation device during the process of filtering solid particles in the waste liquid, please refer to Figures 1-6, an etching waste liquid distillation device provided by the utility model can filter the waste liquid alternately with four mesh plates and can automatically clean the filtered solid particles, improving the subsequent distillation efficiency of the equipment. The distillation device is based on a bottom plate 1. A distillation barrel 2 and a separation box 3 are installed side by side on the top of the bottom plate 1. The separation box 3 is used to remove the solids in the waste liquid and allow the liquid to enter the distillation barrel 2 for distillation. A rotating shaft 4 is rotatably installed inside the separation box 3. A solid-liquid separation fan 5 is fixedly sleeved outside the rotating shaft 4. The solid-liquid separation fan 5 is composed of four mesh plates evenly distributed circumferentially along the center of the rotating shaft 4. The four mesh plates can alternately filter the waste liquid, avoiding too long downtime of the equipment and ensuring the filtering efficiency of the equipment. A partition plate 9 is fixedly installed on the inner bottom wall of the separation box 3. The partition plate 9 can divide the internal space of the separation box 3 into a liquid chamber and a solid chamber to store the solids filtered out by the solid-liquid separation fan 5 separately. And a driving mechanism 6 for driving the solid-liquid separation fan 5 to flip is arranged outside the separation box 3. Each time the driving mechanism 6 drives, it can drive the rotating shaft 4 to rotate 90 degrees clockwise. When the rotating shaft 4 rotates 90 degrees, it can drive the solid-liquid separation fan 5 to rotate 90 degrees, guiding the waste liquid into the liquid chamber. The mesh plate a in the liquid chamber will filter the solid particles in the waste liquid. When a certain amount of solid particles accumulates on the mesh plate a, the solid-liquid separation fan 5 rotates 90 degrees clockwise to flip the mesh plate b to the liquid chamber to continue the filtering work, while the mesh plate a flips upward to pour the solid particles onto the mesh plate c. With the next rotation of the solid-liquid separation fan 5, the solid particles on the mesh plate c can naturally fall into the solid chamber. In this way, the automatic cleaning of the solid particles filtered by the mesh plate can be realized, and the solid particles on the four mesh plates can be uniformly collected into the solid chamber, facilitating the subsequent unified treatment of the solid particles by the work, without the need for the staff to frequently disassemble and clean the solid-liquid separation fan 5, which is convenient for the staff to use and also improves the filtering efficiency of the equipment for the waste liquid.

[0026] As the solid-liquid separation fan 5 flips, although solid particles can automatically slide off the mesh plate by their own gravity, it is inevitable that a small amount of solid particles will adhere to the mesh plate, causing the mesh plate to become blocked. To solve this technical problem, a knocking mechanism 7 for knocking the solid-liquid separation fan 5 is provided on the top of the bottom plate 1. When the mesh plate flips to the solid cavity, the mesh plate can be knocked by the knocking mechanism 7, so that the solid particles adhering to the mesh plate fall off, avoiding blockage of the mesh plate. A bracket 71 slidably installed on the top of the bottom plate 1 is provided, and a strip-shaped groove 72 is opened inside the bracket 71. One side of the inner wall of the strip-shaped groove 72 is rotatably connected to a first connecting rod 73, and the other side of the inner wall of the strip-shaped groove 72 is slidably connected to a mounting seat 74. A second connecting rod 75 is rotatably connected inside the mounting seat 74. The lower ends of the first connecting rod 73 and the second connecting rod 75 are jointly installed with a knocking block 77. The lower ends of the first connecting rod 73 and the second connecting rod 75 are rotatably connected to the knocking block 77. The sliding of the mounting seat 74 can drive the second connecting rod 75 to rotate, and the rotation of the second connecting rod 75 can cooperate with the first connecting rod 73 to drive the knocking block 77 to press down. Similarly, when the mounting seat 74 slides in the reverse direction and resets, it can drive the knocking block 77 to move up. In this way, the knocking block 77 can repeatedly knock the mesh plate in the solid cavity, knocking off the solids adhering to the mesh plate.

[0027] To realize the automatic knocking action of the knocking block 77, an electric push rod 76 is fixedly installed on the top of the bracket 71. The free end of the electric push rod 76 is fixedly connected to the side surface of the mounting seat 74. Driving the electric push rod 76 can drive the mounting seat 74 to slide back and forth, and thus the automatic repeated knocking action of the knocking block 77 can be realized.

[0028] Since the knocking block 77 needs to knock the mesh plate located in the solid cavity, the bracket 71 needs to be arranged above the mesh plate. In this way, when the solid-liquid separation fan 5 flips, when the mesh plate at the top flips into the solid cavity, it will conflict with the bracket 71. To avoid the bracket 71 from hindering the flipping of the solid-liquid separation fan 5, referring to Figures 2 to 3 As shown, transmission mechanisms 8 for pushing the knocking mechanism 7 to move as the solid-liquid separation fan 5 flips are provided on both sides of the bottom plate 1. A gear 81 fixedly sleeved on the end of the rotating shaft 4 is provided. A rack 82 is slidably connected to the side surface of the bottom plate 1. One end of the rack 82 is fixedly connected to the bottom of the bracket 71. The rack 82 meshes with the gear 81, and four evenly distributed teeth are provided on the gear 81. Every time the rotating shaft 4 rotates 90 degrees, it can drive the gear 81 to rotate 90 degrees. When the gear 81 rotates 90 degrees, it can drive the rack 82 to slide. The rack 82 pushes the bracket 71 to slide, and at the same time, the solid-liquid separation fan 5 performs a flipping action, and the bracket 71 can be avoided.

[0029] After the bracket 71 is retracted, the mesh plate needs to be tapped. Therefore, the bracket 71 needs to be reset after the solid-liquid separation fan 5 finishes flipping. A sliding groove 83 for the rack 82 to slide is provided on the bottom plate 1. A telescopic spring 84 is fixedly installed inside the sliding groove 83. One end of the telescopic spring 84 is fixedly connected to the inner wall of the sliding groove 83, and the other end of the telescopic spring 84 is fixedly connected to the end of the rack 82. When the rack 82 pushes the bracket 71 to slide, the telescopic spring 84 can be compressed to deform. When the solid-liquid separation fan 5 finishes flipping, the teeth on the gear 81 are separated from the rack 82, and the smooth part of the gear 81 rotates to the position of the rack 82. The rack 82 can be reset by the elastic force of the telescopic spring 84, and then the bracket 71 can be pulled back to its original position.

[0030] In order to drive the rotation of the rotating shaft 4, a servo motor 61 fixedly installed on one side of the bottom plate 1 is provided. One end of the rotating shaft 4 and the output end of the servo motor 61 are both fixedly connected with belt pulleys 62. A synchronous belt 63 is commonly installed outside the two belt pulleys 62. Driving the servo motor 61 can drive the rotation of the rotating shaft 4 through the belt pulleys 62 and the synchronous belt 63.

[0031] Refer to Figure 1 As shown in the figure, a pipeline is installed between the bottom plate 1 and the distillation barrel 2. A suction pump is provided on the pipeline. And a door panel is hinged on the side of the bottom plate 1 away from the distillation barrel 2. One end of the pipeline communicates with the distillation barrel 2, and the other end of the pipeline communicates with the liquid chamber. The filtered waste liquid can be pumped into the distillation barrel 2 for distillation. When a certain amount of solid particles are collected in the solid chamber, the door panel can be opened to uniformly process the solid particles.

[0032] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model mainly aims to protect mechanical devices. Therefore, the control mode and circuit connection of the present utility model will not be explained in detail.
