Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to an environmentally friendly treatment device for chemical distillation sewage. Background Art

[0002] Chemical wastewater is wastewater discharged from chemical production, including process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site wash water. If discharged without treatment, these wastewaters can cause varying degrees of pollution, endangering human health and impacting industrial and agricultural production. Chemical wastewater requires activated carbon filtration prior to distillation.

[0003] The existing published patent CN117023665B discloses an environmentally friendly treatment device for chemical distillation wastewater. By triggering the cooperation of the ring sleeve and the arc-shaped extrusion strip in the assembly, the cylinder is driven to rotate by the cross-shaped mounting rod. When the ring sleeve and the arc-shaped extrusion strip are separated, the arc-shaped cover in the cylinder is in an open state, which is convenient for removing and filling the activated carbon filter cartridge. When the ring sleeve and the arc-shaped extrusion strip are in contact, the arc-shaped cover in the cylinder is in a closed state, which is convenient for wrapping the inserted activated carbon filter cartridge, thereby quickly completing the replacement of the activated carbon filter cartridge, reducing the normal work of sewage treatment during the replacement process, and speeding up the sewage treatment speed.

[0004] When the above-mentioned device replaces the activated carbon filter cartridge, the cross-shaped mounting rod drives the cylinder to rotate and separate from the input pipe and the connecting pipe, and the sewage inside the cylinder will flow out instantly. The flowing sewage will pollute the entire adsorption mechanism and the ground on which the adsorption mechanism is located. In addition, since the input pipe and the connecting pipe are movably connected to the connecting ring through the elastic rubber layer, during the process of replacing the activated carbon filter cartridge, the elastic rubber layer fixed on the annular groove wall of the connecting ring needs to resist the rotation of the input pipe and the connecting pipe, which will accelerate the wear of the elastic rubber layer and affect the sealing between the input pipe, the connecting pipe and the connecting ring.

[0024] See also Figure 5 The inflatable structure 5 includes two symmetrically distributed cams 501 fixedly sleeved on the outside of the rotating shaft 402. The two cams 501 are located on the outside of the U-shaped tube 2, and two symmetrically distributed sleeves 502 are installed on the outside of the cam 501. The end of the sleeve 502 close to the cam 501 is movably embedded with a spline rod 503 that can move left and right. The end of the spline rod 503 close to the cam 501 is movably embedded with a ball 504, and the connection between the ball 504 and the cam 501 is rolling contact. The ball 504 can reduce the friction between the spline rod 503 and the cam 501. The spline rod 503 is located inside the sleeve 502 and is fixedly connected to a gasket 505.

[0025] See also Figure 5The rubber sleeve 506 is movably in contact with a spring 507 on one side away from the spline rod 503, and the end of the spring 507 away from the rubber sleeve 506 is movably in contact with the sleeve 502.

[0026] See also Figure 4 The filtering structure 3 includes an activated carbon filter cartridge 301, and the outer side of the activated carbon filter cartridge 301 is movably connected to a mounting frame 302, and the connection between the activated carbon filter cartridge 301 and the mounting frame 302 is a plug-in connection, so as to facilitate the replacement of the activated carbon filter cartridge 301, and the connection between the mounting frame 302 and the U-shaped tube 2 is a plug-in connection, and the upper end of the mounting frame 302 is fixedly connected to a top plate 303, and the lower end of the top plate 303 is located on the outer side of the mounting frame 302 and is fixedly embedded with a sealing gasket 304, and the connection between the sealing gasket 304 and the U-shaped tube 2 is a movably abutted connection, and the outer side of the mounting frame 302 is movably connected to two symmetrically distributed positioning channel steels 10, and the connection between the mounting frame 302 and the positioning channel steel 10 is a plug-in connection.

[0027] Working principle: When any activated carbon filter cartridge 301 in the U-shaped tube 2 needs to be replaced, the personnel controls the driving motor 403 to operate, and the driving motor 403 drives the valve plate 401 to rotate toward the side of the activated carbon filter cartridge 301 that needs to be replaced. During the rotation of the valve plate 401, the cam 501 will rotate therewith. During the rotation, the cam 501 drives the spline rod 503 and the rubber sleeve 506 to move through the ball 504. During the movement of the rubber sleeve 506 inside the sleeve 502, the gas in the sleeve 502 is squeezed into the frame-shaped airbag 405 through the conduit 508. The airbag 405 is inflated to fill the gap between the valve plate 401 and the corresponding baffle 404, so that the valve plate 401 and the baffle 404 have good sealing performance. At this time, due to the rotation of the valve plate 401, the sewage in the pipeline on the side where the activated carbon filter cartridge 301 needs to be replaced cannot flow. At this time, when the filtering structure 3 is pulled out from the U-shaped tube 2, there will be no sewage leakage.

[0028] Example

[0029] See also Figure 6 and Figure 7, this embodiment further illustrates Example 1, the positioning channel steel 10 is fixedly connected to the U-shaped tube 2, the positioning structure 7 includes a semi-enclosed sleeve 701 fixedly connected to the positioning channel steel 10, a pin rod 702 that can move left and right is passed through the interior of the semi-enclosed sleeve 701, and the pin rod 702 is provided with a hemispherical portion at one end close to the mounting frame 302, a spherical slot 11 is provided on the outside of the mounting frame 302 for the pin rod 702, and the pin rod 702 is movably connected to the mounting frame 302 through the spherical slot 11, a washer 703 is fixedly sleeved on the outside of the pin rod 702, and a spring 2 704 is movably sleeved on the outside of the pin rod 702, and the two ends of the spring 2 704 are movably abutted against the semi-enclosed sleeve 701 and the washer 703 respectively; When installing the filter structure 3, the hemispherical part of the pin rod 702 will be driven by the spring 2 704 to be stuck in the spherical groove 11, which can position the filter structure 3 so that the sealing gasket 304 at the lower end of the top plate 303 fits tightly with the upper end of the U-shaped tube 2, thereby ensuring good sealing performance between the filter structure 3 and the U-shaped tube 2.

[0030] See also Figure 7 The locking assembly 8 includes a baffle rod 801 that can be movably abutted against one end of the pin rod 702 away from the mounting frame 302. A positioning shaft 802 is fixedly embedded in the center of the baffle rod 801. A coil spring 803 is fixedly sleeved on the outer side of the positioning shaft 802.

[0032] In this embodiment: during the rotation of the valve plate 401, the pull rope 805 on the side of the valve plate 401 close to the filter element that needs to be replaced is in a relaxed state, and the blocking rod 801 on this side rotates under the drive of the coil spring 803, so that the blocking rod 801 rotates away from the pin rod 702 it is against. At this time, when the personnel pulls out the filter structure 3 from the U-shaped tube 2, the hemispherical portion of the pin rod 702 can be easily removed from the spherical slot 11 on the mounting frame 302, thereby facilitating the disassembly and assembly of the filter structure 3, and the pull rope 805 on the side of the valve plate 401 close to the sewage flow is in a relaxed state. The rope 805 is in a taut and straightened state, and the baffle 801 on this side will rotate to a horizontal state under the tension of the rope 805. At this time, one end of the baffle 801 will press against one end of the pin rod 702 to prevent the pin rod 702 from moving. Since the pin rod 702 cannot move, the hemispherical part of the pin rod 702 cannot be removed from the spherical slot 11 on the mounting frame 302, so the filter structure 3 on this side cannot be separated from the U-shaped tube 2, which is conducive to locking the filter structure 3, and the filter structure 3 on the side where the sewage flows in the pipeline becomes loose.
