Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a lead-zinc ore beneficiation wastewater back pumping device. Background Technology
[0002] During the lead-zinc ore beneficiation process, the wastewater produced contains a large amount of large particles such as sand and gravel. If these large particles are allowed to directly enter the pipeline system during the wastewater pumping process, it will not only cause rapid damage to the pump body, but also cause wear on the valves in the pipeline system, greatly reducing the service life of the valves.
[0003] Traditionally, in lead-zinc mine wastewater treatment, impurity collection and wastewater filtration are often two relatively independent steps that need to be performed separately. When wastewater passes through a filtration device for purification, impurities are trapped on the filter media. However, as impurities accumulate, the filtration efficiency of the filter media gradually decreases, and may even lead to blockage, requiring a shutdown for impurity cleaning. This process not only disrupts the continuity of wastewater treatment and reduces overall treatment efficiency, but may also increase the difficulty and cost of subsequent treatment due to wastewater accumulation caused by shutdown. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a lead-zinc ore beneficiation wastewater back-pumping device, which solves the problem that traditional wastewater treatment devices often need to clean impurities while the machine is shut down when treating lead-zinc ore beneficiation wastewater. This not only affects the treatment efficiency, but may also increase the difficulty of subsequent treatment due to the accumulation of wastewater caused by the shutdown.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lead-zinc ore beneficiation wastewater back-extraction device, comprising an outer shell, an inlet connected to one end of the outer shell, an outlet connected to the side of the outer shell, and a side shell connected to the other end of the outer shell. A cleaning assembly is installed on the side shell, the cleaning assembly comprising a rotating shaft, the rotating shaft being rotatably clamped onto the side shell, a spiral blade connected to the outer side of the rotating shaft via a connecting rod, the spiral blade being rotatably installed inside a filter cartridge, the filter cartridge being clamped between the outer shell and the side shell, a sludge discharge pipe connected to the lower side of the side shell, the sludge discharge pipe being connected to one end of a ball valve, and the other end of the ball valve being connected to a collection box.
[0006] The beneficial effects of this utility model are: when collecting impurities filtered by the filter cartridge and removing impurities temporarily stored in the collection box, wastewater collection can be carried out continuously throughout the process without affecting the normal filtration of wastewater, which greatly improves the efficiency of wastewater filtration and treatment.
[0007] For easy cleaning and replacement of the filter cartridge;
[0008] As a further improvement to the above technical solution: flanges are welded to the ends of both the side shell and the outer shell, and the side shell and the outer shell are connected by a flange and bolt structure.
[0009] The beneficial effects of this improvement are: the side housing can be quickly removed from the outer housing, allowing personnel to easily remove the filter cartridge for cleaning or replacement.
[0010] In order to ensure that the sand and gravel filtered inside the filter cartridge can effectively enter the side shell under the conveying of the filter cartridge;
[0011] As a further improvement to the above technical solution: one end of the spiral blade extends into the interior of the side shell, and the inner diameter of the side shell is the same as the inner diameter of the filter cartridge.
[0012] The beneficial effect of this improvement is that when the spiral blades rotate, the sand and gravel filtered in the filter cartridge can be transported to the side shell without obstruction.
[0013] For easy rotation of the helical blades;
[0014] As a further improvement to the above technical solution: a handwheel is connected to the end of the rotating shaft away from the spiral blade.
[0015] The beneficial effect of this improvement is that the operator can easily rotate the spiral blades by using the handwheel.
[0016] In order to quickly empty the sand and other impurities collected in the collection box;
[0017] As a further improvement to the above technical solution: the collection box is threadedly connected to a ball valve.
[0018] The beneficial effect of this improvement is that the collection box can be quickly unscrewed from the ball valve, making it convenient for personnel to empty the sand, gravel, and other impurities collected in the collection box.
[0019] In order to smoothly collect impurities inside the filter cartridge;
[0020] As a further improvement to the above technical solution: the mud discharge pipe has a variable diameter structure that is wider at the top and narrower at the bottom.
[0021] The beneficial effect of this improvement is that the variable diameter structure allows impurities transported by the filter cartridge to fall quickly into the interior of the sludge discharge pipe.
[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0028] like Figure 1 As shown in Figure 3, a lead-zinc ore beneficiation wastewater back-extraction device includes an outer shell 1. One end of the outer shell 1 is connected to an inlet 3, and the side of the outer shell 1 is connected to an outlet 2. The other end of the outer shell 1 is connected to a side shell 4. A cleaning assembly 5 is installed on the side shell 4. The cleaning assembly 5 includes a rotating shaft 51, which is rotatably clamped onto the side shell 4. The outer side of the rotating shaft 51 is connected to a spiral blade 54 via a connecting rod 53. The spiral blade 54 is rotatably installed inside a filter cartridge 6, which is clamped between the outer shell 1 and the side shell 4. A sludge discharge pipe 7 is connected to the lower side of the side shell 4. The sludge discharge pipe 7 is connected to one end of a ball valve 8, and the other end of the ball valve 8 is connected to a collection box 9. During the collection of impurities filtered by the filter cartridge 6 and the removal of impurities temporarily stored in the collection box 9, wastewater collection is continuous throughout the process without affecting normal wastewater filtration, greatly improving the efficiency of wastewater filtration and treatment. Flanges are welded to the ends of both the side housing 4 and the outer housing 1. The side housing 4 and the outer housing 1 are connected by flanges and bolts. The side housing 4 can be quickly detached from the outer housing 1, allowing personnel to easily remove the filter cartridge 6 for cleaning or replacement. One end of the spiral blade 54 extends into the interior of the side housing 4. The inner diameter of the side housing 4 is the same as the inner diameter of the filter cartridge 6. When the spiral blade 54 rotates, it can transport the sand and gravel filtered in the filter cartridge 6 into the side housing 4 without obstruction. The end of the rotating shaft 51 away from the spiral blade 54 is connected to a handwheel 52. The operator can easily drive the spiral blade 54 to rotate using the handwheel 52. The collection box 9 is threadedly connected to the ball valve 8. The collection box 9 can be quickly unscrewed from the ball valve 8, making it convenient for personnel to empty the sand and gravel and other impurities collected in the collection box 9. The mud discharge pipe 7 has a variable diameter structure that is wider at the top and narrower at the bottom. The variable diameter structure allows the impurities transported by the filter cartridge 6 to fall quickly into the interior of the mud discharge pipe 7.
[0029] The working principle of this technical solution is as follows: the inlet 3 and outlet 2 are machined on-site using existing threaded, flanged, or other connection methods, and then connected to the inlet pipe and the water pump inlet pipe, respectively; during the operation of the device, wastewater enters the interior of the filter cartridge 6, and large particles such as sand and gravel in the wastewater are filtered and retained inside the filter cartridge 6, while the water is pumped out through the sieve holes of the filter cartridge 6 and the outlet 2; after opening the ball valve 8, the operator can turn the handwheel 52, which drives the spiral blades through the rotating shaft 51 and the connecting rod 53. The rotating spiral blades 54 transport the sand and gravel in the filter cartridge 6 to the sludge discharge pipe 7, and then, under the action of gravity, they fall into the collection box 9, causing the collection box 9 to discharge the corresponding volume of water upwards. When it is necessary to remove the impurities collected in the collection box 9, the operator closes the ball valve 8 and removes the collection box 9 to pour out the impurities. During the collection of impurities filtered by the filter cartridge 6 and the removal of impurities temporarily stored in the collection box 9, the wastewater collection is carried out continuously throughout the process without affecting the normal filtration of wastewater, which greatly improves the efficiency of wastewater filtration and treatment.
