[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Reference Figures 1-3The utility model provides a kind of solid-liquid separation device of high-salinity wastewater, including box 1, the solid-liquid separation device of high-salinity wastewater is equipped with inclined transmission belt 2 in the inside upper end of box 1, and the solid-liquid separation device of high-salinity wastewater is equipped with drive assembly outside box 1 and drives transmission belt 2 rotation.

[0022] The solid-liquid separation device of high-salinity wastewater is equipped with vertical baffle 5 in box 1, and the solid-liquid separation device of high-salinity wastewater is arranged as liquid cavity 6 to the inclined lower end of transmission belt 2 side of baffle 5, and the other side is solid cavity 7.The solid-liquid separation device of high-salinity wastewater is detachably connected with filter plate 8 in liquid cavity 6, and the solid-liquid separation device of high-salinity wastewater is slidably equipped with knocking block 9 below transmission belt 2 on both sides of the upper portion of solid cavity 7, and the side wall of the solid-liquid separation device of high-salinity wastewater is equipped with intermittent assembly for driving knocking block 9 to knock filter frame 3 intermittently.

[0023] The solid-liquid separation device of high-salinity wastewater should be equipped with water inlet pipe on the top of liquid cavity 6, and water outlet pipe should be equipped at the bottom of liquid cavity 6.Industrial wastewater enters box 1 from water inlet pipe, and flows to filter screen 4. Larger solid materials are intercepted by filter screen 4, and wastewater flows to the lower end of transmission belt 2, and wastewater is discharged from water outlet pipe after fine filtration by filter plate 8.

[0024] It should be noted that the two sides of transmission belt 2 should be attached to the side wall of box 1, and the two sides of filter frame 3 should be attached to the side wall of box 1, so as to avoid wastewater flowing directly from the side wall of box 1. Filter frame 3 can be n-shaped, so as to avoid blocking the flow of wastewater as much as possible.

[0025] Drive assembly drives transmission belt 2 to rotate, and filter frame 3 in liquid cavity 6 moves to solid cavity 7, and filter frame 3 is flipped when it moves to the end of rotating belt, and knocking block 9 is driven by intermittent assembly to knock filter frame 3 intermittently, and solid materials on filter screen 4 fall and are collected at the bottom of solid cavity 7.

[0026] The side wall of solid cavity 7 can be provided with a cleaning port, and when a large amount of solid impurities are collected in solid cavity 7, they can be directly cleaned out from the cleaning port without affecting normal work. When a large amount of solid impurities are collected on filter plate 8, the device needs to be stopped and the filter plate 8 needs to be replaced. Since the wastewater has been filtered by filter screen 4 for many times before reaching filter plate 8, the remaining solid materials are less, so the filter plate 8 is not cleaned frequently.

[0027] In order to avoid wastewater directly flowing from filter frame 3 to the lower end of transmission belt 2 as much as possible, the filter frame 3 of the solid-liquid separation device of high-salinity wastewater in the middle of transmission belt 2 is in vertical state. In addition, the bottom end of the water inlet pipe should be close to the top end of the filter frame 3 as much as possible, so as to avoid large splashing of wastewater.

[0028] Referring to Figure 2 , Figure 4 , the high-salinity wastewater solid-liquid separation device is characterized in that the upper portion of the solid cavity 7 is provided with a chute 10 on the two side walls, the high-salinity wastewater solid-liquid separation device intermittent assembly comprises a spring 11 arranged in the chute 10, and one end of the spring 11 is fixedly connected to the side surface of the knocking block 9, and the other end is fixedly connected to the side wall of the chute 10.

[0029] In order to enable the spring 11 to drive the knocking block 9 to move and knock the filter frame 3, the spring 11 of the high-salinity wastewater solid-liquid separation device is always in a stretched state during the movement of the knocking block 9. In order to achieve the above effect, the chute 10 of the high-salinity wastewater solid-liquid separation device is fixedly connected with a baffle 12 on the outer side of the end away from the partition plate 5. The baffle 12 is used to limit the movement of the knocking block 9, so that the spring 11 is always in a stretched state.

[0030] The high-salinity wastewater solid-liquid separation device is characterized in that the transmission belt 2 is provided with a belt pulley 13 at both ends, the high-salinity wastewater solid-liquid separation device driving assembly comprises a motor 14 fixedly installed on the outer side wall of the box body 1, one of the belt pulleys 13 is driven to rotate by the motor 14, and the two belt pulleys 13 are synchronously rotated by cooperation of the transmission belt 2.

[0031] Since the knocking of the knocking block 9 may have a certain influence on the motor 14, in order to avoid the above problem, the motor 14 of the high-salinity wastewater solid-liquid separation device drives the lower belt pulley 13 to rotate, so that the motor 14 is away from the knocking position, and the vibration caused by the knocking is buffered by the long transmission belt 2, so that the influence on the motor 14 is limited.

[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
