Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, and in particular to a solid-liquid separator for water pollution prevention and control. Background Technology

[0002] Before wastewater treatment, solid impurities are separated to improve the quality of subsequent wastewater treatment. An existing solid-liquid separator for water pollution control, with publication number CN 222752704 U, involves injecting wastewater into a separation tank through an inlet. The wastewater then falls onto a conveyor belt, where solids are intercepted, while liquids pass through filter holes on the conveyor belt and fall to the bottom of the separation tank. This liquid then flows out of the separation tank through an outlet. However, this device, which uses a horizontally rotating conveyor belt to separate solids from wastewater, has a poor separation efficiency and urgently needs improvement. Utility Model Content

[0003] The purpose of this invention is to provide a solid-liquid separator for water pollution control in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions: A solid-liquid separator for water pollution control includes a separation tank with a water inlet at the top and a water outlet at the bottom. Slag outlets are located on both side walls of the separation tank. A solid-liquid separation mechanism is located inside the separation tank above the slag outlets. The solid-liquid separation mechanism includes a support shaft mounted on the separation tank, a filter screen fixedly mounted on the support shaft, and a swing mechanism that causes the filter screen to swing laterally through the separation tank at one end of the support shaft. The swing mechanism includes a gear fixed to the end of the support shaft. A fan-shaped rotating disk is rotatably mounted on the outer wall of the separation tank via a rotating shaft. A groove is formed on the arc-shaped surface of the fan-shaped rotating disk, and an arc-shaped gear ring is installed in the groove. Limit blocks are fixed at both ends of the arc-shaped surface of the fan-shaped rotating disk. The arc-shaped gear ring meshes with the gear. A vertical connecting groove is formed on the fan-shaped rotating disk, and a power component that causes the fan-shaped rotating disk to rotate intermittently is connected to the connecting groove.

[0005] Further configuration: The support shaft is rotatably connected to the separation box, and the filter screen is attached to the inner wall of the separation box.

[0006] Further configuration: The power assembly includes a connecting rod rotatably connected to the connecting groove, a geared motor mounted on the side wall of the separation box, a cam mounted on the output end of the geared motor, and the other end of the connecting rod rotatably connected to the cam via a pin.

[0007] Further configuration: The arc-shaped gear ring is slidably connected to the fan-shaped rotating disk.

[0008] Further features: The bottom of the inner side of the separator is inclined downward toward the outlet, and a guide plate is installed on the outer wall of the separator below the slag outlet.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By connecting the swing mechanism on the solid-liquid separation mechanism, the power component pulls the fan-shaped rotating disk to rotate intermittently. The limit blocks on both sides of the fan-shaped rotating disk alternately push the arc-shaped gear ring, causing the arc-shaped gear ring to mesh with the gear and rotate. This drives the filter screen on the support shaft to tilt to one side alternately, causing the impurities on the filter screen to flow and be discharged towards the slag outlet, thus improving the separation effect of solid impurities in sewage.

[0015] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-5 As shown, a solid-liquid separator for water pollution control includes a separation tank 1. A water inlet 11 is located at the upper end of the separation tank 1, and a water outlet 14 is located at the lower end of the separation tank 1. Sludge outlets 12 are provided on both side walls of the separation tank 1. The bottom inner side of the separation tank 1 slopes downwards towards the water outlet 14. A guide plate 13 is provided on the outer wall of the separation tank 1 below the sludge outlet 12 to guide the flow of filtered solid impurities. A solid-liquid separation mechanism is provided inside the separation tank 1 above the sludge outlet 12. The solid-liquid separation mechanism includes a support shaft 21 mounted on the separation tank 1, a filter screen 22 fixedly mounted on the support shaft 21, and the support shaft 21 rotatably connected to the separation tank 1. The filter screen 22 is in contact with the inner wall of the separation tank 1. One end of the support shaft 21 passes through the separation tank 1 and is connected to a swinging mechanism that causes the filter screen 22 to swing from side to side. In this embodiment: the rocking mechanism includes a gear 31 fixed to the end of the support shaft 21, a fan-shaped rotating disk 32 rotatably mounted on the outer wall of the separation box 1 via a rotating shaft, a groove is provided on the arc surface of the fan-shaped rotating disk 32, an arc-shaped gear ring 34 is installed in the groove, limit blocks 33 are fixed at both ends of the arc surface of the fan-shaped rotating disk 32, the arc-shaped gear ring 34 meshes with the gear 31, a vertical connecting groove 321 is provided on the fan-shaped rotating disk 32, a power component that causes the fan-shaped rotating disk 32 to rotate intermittently is connected to the connecting groove 321; the arc-shaped gear ring 34 is slidably connected to the fan-shaped rotating disk 32; The power assembly includes a connecting rod 35 rotatably connected to the connecting groove 321, a geared motor 36 mounted on the side wall of the separation box 1, a cam 37 mounted on the output end of the geared motor 36, and the other end of the connecting rod 35 rotatably connected to the cam 37 via a pin. The working of the geared motor 36 drives the cam 37 to rotate. When the cam 37 rotates, it pulls the fan-shaped rotating disk 32 to reciprocate intermittently. The limiting blocks 33 on both sides of the fan-shaped rotating disk 32 alternately push the arc-shaped gear ring 34, causing the arc-shaped gear ring 34 to mesh and rotate with the gear 31, which drives the filter screen 22 on the support shaft 21 to tilt to one side, so that the impurities on the filter screen 22 flow to one side and are discharged through the slag outlet 12.

[0016] The working principle and usage process of this utility model: Wastewater is added into the separation box 1 through the water inlet 11. During the falling process, the filter screen 22 filters the solid impurities in the wastewater. At the same time, the reduction motor 36 drives the cam 37 to rotate. When the cam 37 rotates, it pulls the fan-shaped rotating disk 32 to rotate intermittently through the connecting rod 35. During the rotation, the limit block 33 on one side pushes the arc-shaped gear ring 34 to rotate with the fan-shaped rotating disk 32, so that the arc-shaped gear ring 34 meshes with the gear 31 and rotates, causing the filter screen 22 on the support shaft 21 to tilt to one side, so that the impurities on the filter screen 22 flow to one side and are discharged through the slag outlet 12. The filtered water is discharged from the water outlet 14 on the lower side.
