Description

Technical Field

[0001] The utility model belongs to the technical field of zinc ingot production equipment, in particular to a wastewater solid-liquid separation device in the production of zinc ingots. Background Art

[0002] Zinc ingot production is one of the most common production directions in metal smelting at this stage. Zinc ore is put into a smelting furnace to extract zinc solution, and then injected into the mold again after cooling and other processes to form zinc ingots for easy recovery. However, a lot of wastewater is also generated in the production of zinc ingots, and the wastewater also contains a lot of particulate matter. In addition, this part of the wastewater needs to be separated from the solid and liquid to meet the production emission requirements. Therefore, the solid-liquid separation device is particularly important in the production of zinc ingots.

[0003] A Chinese patent application (or patent) with publication number CN214634360U discloses a solid-liquid separation device for wastewater after evaporation in zinc ingot production, including a treatment separation box, a sealing cover corresponding to the treatment separation box is movably installed on the top of the treatment separation box, a sealing ring corresponding to the treatment separation box is fixedly installed on the bottom of the sealing cover, and an exhaust pipe is fixedly installed on the top of the sealing cover. The solid-liquid separation device for wastewater after evaporation in zinc ingot production is provided with a telescopic seat. When the telescopic seat is in operation, it can drive the sealing cover and the collection box at the bottom to rise slowly together. The crystals rising to the inside of the collection box can be easily collected and positioned by the user. By providing a reflux pump, the clear liquid at the top can be easily recovered and recycled for re-filtration. The positioning pin is fixedly installed at the bottom of the collection box to effectively avoid the phenomenon of displacement during resetting.

[0004] The above-mentioned zinc ingot production wastewater solid-liquid separation device after evaporation has a reflux pump fixedly installed on the right side of its mounting plate, and a liquid extraction pipe extending to the inside of the treatment separation box is fixedly installed on the input end of the reflux pump, that is, the supernatant liquid is extracted from the treatment separation box into the filter box through the reflux pump, but because the reflux pump is fixedly installed and the position of the pump pipe at its liquid inlet end is not adjustable, it can only reflux the clear liquid above its pump pipe, and it is not applicable when the liquid level of the clear liquid is below the pump pipe inlet end; and, a telescopic seat is fixedly installed on the back and front of the device, and the telescopic seat is connected to the sealing cover and the collection box inside the treatment separation box through a transmission rod, so that the sealing cover and the collection box can be synchronously raised or lowered through the telescopic effect of the telescopic seat, but the collection box itself is a flat box-shaped structure. Even if the collection box moves to the top of the treatment separation box under the traction of the telescopic seat, it is difficult to remove the solid particles from the treatment separation box because the solid particles are dispersed and retained inside the collection box. To this end, we provide a wastewater solid-liquid separation device in zinc ingot production to solve the above-mentioned problems. Utility Model Content

Specific embodiment 1

[0029] See also Figure 1-4 The utility model is a wastewater solid-liquid separation device in zinc ingot production, comprising a separation box 1 and a driving assembly 2 mounted on both sides thereof, wherein the end of a hydraulic rod 202 in the driving assembly 2 is connected to a screening box 301 in a separation assembly 3, and the screening box 301 can be driven to move up and down by the hydraulic rod 202.

[0030] Specifically, a mounting block 102 is welded at the corner of the upper side wall of the separation box 1, and the separation box 1 is connected to the hanging frame 201 through the mounting block 102, and a hydraulic rod 202 is also hoistedly installed on the hanging frame 201, and the bottom of the hydraulic rod 202 is connected to the screening box 301, and a sieve plate 301a is embedded on the bottom side wall of the screening box 301.

[0031] Furthermore, side grooves 101 are opened on the inner wall at the four corners of the screening box 1, and a pipe groove 103 is opened on the right side wall of the separation box 1, and the pipe groove 103 is clamped with the outer wall of the water inlet pipe 405, and angle plates 301e are welded on the outer walls at the four corners of the screening box 301, and the angle plates 301e are slidingly connected to the side grooves 101, and the upper side walls of the angle plates 301e are connected to the axial end of the hydraulic rod 202 through the pipe sleeve 204, and the bottom side walls of the angle plates 301e are in contact with the bottom side walls of the side grooves 101 through the spring 301f, and the spring 301f can have an anti-collision effect, and a fixing sleeve 301b is welded on the side wall of the screening box 301, and the fixing sleeve 301b is detachably fixedly connected to the suction pipe 406.

[0032] The operation process of this embodiment is as follows: when in use, the hydraulic rod 202 in the driving component 2 can drive the screening box 301 on its shaft end to move up and down. When it moves up, the wastewater in the zinc ingot production can be put into the screening box 301, and then the sieve plate 301a at the bottom can screen this part of the wastewater, so that the solid particles are retained in the screening box 301, and the solution passes through the sieve plate 301a and flows to the bottom of the screening box 301, and after the wastewater solution is put in once, the hydraulic rod 202 is extended again, and the screening box 301 is sunk to the liquid surface position for soaking, and then the hydraulic rod 202 retracts again, and the screening box 301 moves up until it moves to the top port position of the separation box 1 and stops. Specific embodiment 2

The discharge door 402 is slidably installed in the door slot 301c of the screening box 301, and the discharge door 302 is a folding door structure. When it is not in use, that is, in a closed state, the telescopic rod 302c thereon pushes the discharge door 302 to extend, thereby achieving the effect of closing the screening box 301. When it is necessary to take out the particulate matter in the zinc ingot wastewater therein, the discharge door 302 can be compressed by the traction rope 302d to make it folded.

[0034] Specifically, a center hole 302a is opened at the center of the discharge door 302, and side holes 302b are opened on the upper and lower sides of the center hole 302a and inside the discharge door 302, and a telescopic rod 302c is also installed in the side hole 302b.

[0038] Specifically, the extraction component 4 includes a pump body 401 and a water storage tank 403 connected thereto via a water outlet pipe 402. Meanwhile, a water inlet pipe 405 is sleeved on the water inlet of the pump body 401, and the other end of the water inlet pipe 405 is connected to a suction pipe 406 via a folding tube 405a.

[0039] Furthermore, a fixing frame 404 is clamped on the side wall of the bottom of the water storage tank 403, and the water storage tank 403 is connected to the side wall of the separation box 1 through the fixing frame 404, and a screen 406a is inlaid on the side wall of the suction pipe 406.

[0040] The operation process of this embodiment is as follows: the pump body 401 works, and the negative pressure is transmitted to the suction pipe 406 through the water inlet pipe 405, so that the suction pipe 406 sucks the wastewater solution in the internal chamber of the separation box 1, and during the suction process, the screen 406a on its side can filter and screen particulate matter. At the same time, when adjusting the suction position, the suction pipe 406 moves up and down with the screening box 301, and during the movement, the folding tube 405a can be compressed, folded or stretched and extended. Finally, the pump body 401 discharges the wastewater solution into the water storage tank 403 through the water outlet pipe 402.
